gehrt ); indeed, we have not met many conservation biologists who are not firmly aboard the malthusian ship. we argue that population growth also burdens personal liberty by creating a need for greater regulation. parsons ( ) discussed the rela- tionship between population and liberty; we extend that argument to conservation. people unmoved on the pop- ulation issue with conservation arguments may be moved by our regulation argument. the problems faced by conservationists have changed. one hundred years ago, the predominant problem facing wildlife in north america was overexploitation. water- fowl, forest carnivores, and ungulates were exploited, largely for market, and were minimally regulated, to the point where most were near extinction. deer ( odocoileus virginianus ) populations were especially depleted and heading toward extirpation throughout the eastern united states. the american colonies began limiting hunting methods, seasons, and equipment in the mid- s to deal with overexploitation (trefethen ). passage of the lace act of , which made it a federal offense to trans- port illegally killed wildlife across state borders, further defined the public right to wildlife and helped curb over- exploitation. these regulations marked the beginning of the end of wildlife populations being considered unpro- tected public property. unregulated taking had exacted a lasting toll on some north american wildlife. for ex- ample, the passenger pigeon ( ectopistes migratorius ), which once flew in flocks of billions, was extinct by , largely because of unregulated taking of pigeons for mar- ket (blockstein & tordoff ). at about the same time, carnivores such as lynx ( lynx canadensis ) and moun- tain lions ( puma concolor ) were exploited to local ex- tinction in the northeastern united states (godin ). as the human population grew, wildlife conservation and management developed as an applied scientific disci- pline with a focus on reducing or controlling consump- tion by humans and increasing production of wildlife. specifically, the works of aldo leopold, particularly game management (leopold ) and “the upshot” (in a sand county almanac , leopold ), focused our attention on wildlife as a renewable but finite resource and halted our illusion of boundless wildlife populations. as conservationists we can be proud of our many suc- cesses. game species have rebounded, and predators— long maligned for their way of life—are making tremen- dous comebacks. mountain lions have returned to much of their former range in the western united states and are slowly returning in the east. the wolf ( canis lupus ) has gradually returned to the rocky mountains, and there is even an active campaign to reintroduce the grizzly bear ( ursus arctos horribilis ) to parts of its former range. the u.s. public has demonstrated through laws, regulation, and private actions that it values these species and their habitats, at least in certain places and times, more than competing human uses. our glaring failure, however, has been in treating the symptoms of wildlife conservation problems rather than their root causes. the world’s human population, currently approxi- mately billion, is growing ( births minus deaths) at a rate of people per second, or approximately , people each day (united nations ). natural resource managers must deal with this growth, and plant and ani- mal life must adapt or perish. what happens when we compromise in the conflict between wildlife habitat and the demands of more people? the trade-offs almost al- ways mean a net increase in the proportion of earth’s productivity allocated to human use and a net decrease in the proportion allocated to wild areas and wild life. the effect of humans on our environment is a func- tion of per capita consumption of resources times the number of people consuming those resources. in some cases we have done a fair job of convincing people to re- duce consumption and protect some habitat. if, how- ever, we reduce per capita consumption but the num- * email pletsch@forestry.umt.edu paper submitted january , ; revised manuscript accepted may , . conservation biology volume , no. , december pletscher & schwartz population growth ber of humans increases by similar or higher rates, what have we gained? in addition, if we protect some habitat but the human population increases by higher rates, what have we gained? we argue that we have lost: space per individual, wild species, and wild areas. in addition, by ignoring the population problem, we lose individual freedoms because of the need for increased regulation. for example, years ago, people in the western united states could harvest bison at any rate they wished. with an increased market and more harvesters, laws and regulations were enacted to stop overharvest (trefethen ). at the turn of the last century, people could dump their wastes into rivers with little noticeable effect. now, with an in- creased number of residents and more wastes per capita, laws and regulations are in place to maintain water quality. we examined the montana laws restricting fishing, hunting, and access to lands for these activities and found that in the general laws required only sections of code and pages of text (montana territorial legislature ; montana legislature ). today, montana has sections of code spanning pages of text (montana legislature ). population growth is not the only fac- tor causing increases in regulations, but we believe it to be the primary and most overlooked, factor. we continue to pass more laws and regulations to control both supply and demand in an over-taxed system; thus, our individual free- doms are inversely proportional to our population. one of our most basic freedoms is our reproductive freedom, but uncontrolled population growth leads to a reduction in all other freedoms, a tyranny of population growth. despite this tyranny, taking away reproductive freedom is not morally acceptable, socially feasible, or politically possible. what we can do, quite easily, is raise awareness that human population growth is the cause of most of our environmental ills and leads to increased regulation. few conservation issues are unaffected by human population pressures, and we must demonstrate these relationships. for instance, when talking about the effects of subdivided land on biodiversity, we can point out the root of the problem. when talking about problems of access on pri- vate lands or the institution of recreation fees, we can in- dicate why they are occurring. and when we discuss air- quality regulations that prevent open burning or require tougher industrial standards, we should discuss the ulti- mate root of the problem. the tradeoffs should be identi- fied explicitly. increased human population equals in- creased pressure for regulation. furthermore, we must not only preach to the converted. these messages should be delivered to groups outside the society for conserva- tion biology, especially to those people who traditionally are uninterested in the outdoors but who have an interest in seeing government reduced. in other words, if popula- tion growth is the primary culprit hindering the conserva- tion of biodiversity, we should not stop short of enlisting political groups who are interested for different reasons. let conservation make strange bedfellows. we must continue to encourage a reduction in con- sumption and work on increasing efficiency on those lands producing goods and services. we must also con- tinue to encourage shared uses of our wild lands and nat- ural resources. but if this is all we do, we will continue to tinker while our wildlife legacy is lost. we must point out to anyone who will listen—and to recognize ourselves— that human population growth is a grave threat to indi- vidual freedom and to all that we as conservationists hold dear. there are no easy answers, but education is a start. thomas jefferson, the third american president and framer of the u.s. constitution, argued that it is the re- sponsibility of the current generation to undertake ac- tions that will maintain the freedom of the next genera- tion. by ignoring the population issue, we not only lose our valuable wild areas and wild life, but we infringe on the freedoms of the next generation. the earth belongs to each of these generations during its course, fully and in its own right. the second generation receives it clear of the debts and encumbrances of the first, the third of the second, and so on. for if the first could charge it with a debt, then the earth would belong to the dead and not to the living generation. thomas jefferson ( ) ( foner : ) acknowledgments we thank j. w. thomas, g. schildwachter, j. belsky, j. burchfield, and two anonymous reviewers for comment- ing on an early draft of this essay. literature cited blockstein, d. e., and h. b. tordoff. . gone forever: a contempo- rary look at the extinction of the passenger pigeon. american birds : – . foner, p. s., editor. . letter from thomas jefferson to james madi- son. pages – in basic writings of thomas jefferson. willey book company, new york. gehrt, s. d. . the human population problem: educating and changing behavior. conservation biology : – . godin, a. j. . wild mammals of new england. johns hopkins uni- versity press, baltimore. leopold, a. . game management. scribner’s sons, new york. leopold, a. . a sand county almanac and sketches here and there. oxford university press, new york. meffe, g. k. . human population control: the missing awareness. conservation biology : – . montana legislature. . montana codes annotated. montana legis- lative services division, helena. montana legislature. . montana codes annotated. montana legis- lative services division, helena. montana territorial legislature. . revised statutes of montana. george e. boos, helena. parsons, j. . population versus liberty. pemberton books, london. trefethen, j. b. . an american crusade for wildlife: highlights in con- servation progress. the telegraph press, harrisburg, pennsylvania. united nations. . department of economic and social affairs, pop- ulation division. world population . publication st/esa/ser.a/ , no. e. . . . united nations, new york. sscience publisher: richard s. nicholson editor-in-chief: daniel e. koshland, jr. editor: ellis rubinstein managing editor: monica m. bradford deputy editors: philip h. abelson (engineering and ap- plied sciences);

anantharaman rt, shepherd md the university of texas at austin, austin, tx, usa there exists an ongoing debate regarding the effect of direct-to-consumer (dtc) advertising spending on drug prices. the two opposite views are: (a) increase in dtc advertising spending would be added to drug prices (b) dtc advertising would increase competition and thus reduce drug prices. objective: explore the relationship of dtc advertis- ing spending and drug pricing for the top twenty drugs from to . methods: top twenty drugs were selected on the basis of their dtc advertising spending (source: competitive media reporting, ny) for . for analysis, average wholesale price (awp) per unit was used from the blue book awp unit pricing. for each of the top twenty drugs, the following trend graphs were plotted for to : (a) the total dtc advertising spending and per unit price of the drug; (b) the percent changes in the dtc advertis- ing spending and drug price. the percent change in dtc advertising spending and drug price for a year was calculated as percent change from the previous year. results: only sildenafil (viagra) and sibutramine (meridia) showed an increase in the actual drug price with an increase in the dtc advertising spending. however, for these two drugs in year , the percent change in dtc advertising spending decreased and the percent change in drug price increased. no trend was evident from the graphs of the other eighteen drugs. on an average dtc advertising spending for most of the drugs decreased with time while drug prices continued to increase. conclusion: results indicate a very weak relation- ship between dtc advertising spending and drug prices. the increase in drug price in spite of the decrease in the dtc advertising spending contradicts both rationale i.e. dtc advertising spending reduces drug price through competition or increase in drug price is due to increase in dtc advertising spending. hp impact of direct to consumer advertising—the consumer search for information belazi dt , crawford a , pizzi l thomas jefferson university & abbott laboratories, philadelphia, pa, usa; thomas jefferson university, philadelphia, pa, usa objective: the purpose of this study is to identify factors associated with consumers’ seeking various infor- mation sources about medications sought in response to direct to consumer advertising. methods: in the spring and summer of , the fda, division of drug marketing, advertising, and commu- nication conducted a national telephone survey of adults regarding direct-to-consumer (dtc) promotion of prescription drugs and its effects on visits to the doctor. in addition to consumer attitudes, opinions and responses to direct to consumer advertising, the survey also elicited responses regarding consumer utilization of information sources such as reference books, -telelphone number, and health care providers. there were total respon- dents, of whom completed the required questions regarding information sources. chi square analysis was used to assess associations between consumer demographic information and the different types of informational resources that consumers used after exposure of direct to consumer advertising. results: the analysis showed significant associations (p £ . ) between gender, race, education, health status, self-perceived knowledge of health, prescription medication use, and internet use and many of the following information resources: reference books, asking friends/neighbors, -telephone number, primary doctor, pharmacist, specialist, and nurse. across all information sources, female gender, decreased health status, low education, and higher than average medica- tion use were the variables that had the strongest associ- ations. a model was developed depicting the associations between these findings. results pertaining to specific sources will be presented. conclusions: this study evaluated how different consumers seek information from different sources as a result of direct to consumer advertising. this study will assist those interested in identifying and further educat- ing consumers about their health and novel treatments or therapies. hp fda regulatory actions against misleading or unsubstantiated economic and quality-of-life claims: an analysis of warning letters and notices of

france; lewisham hospital, london, uk; boehringer ingelheim, ingelheim, germany introduction: measuring quality of life (qol) has become a vital part of assessing lower limb ischemia and peripheral vascular disease in international studies. the -item vascuqol was developed in uk english and investigates domains: symptoms, pain, activities, social life and emotional state. prior to use in an international trial the measure underwent linguistic validation in lan- guages. methods: a qol specialist coordinated the translation process in each target country using the fol- lowing methodology: ) two forward translations by pro- fessional, native speaking translators of the target lan- guage fluent in english; ) comparison and reconciliation of the translations by a qol specialist and translators; ) backward translation by a native english speaker; ) comparison of the source and backward versions; ) re- view of the translation by a clinician in each country; ) comprehension test in a sample target population; ) in- ternational harmonization. results: linguistic and conceptual issues emerged when translating idiomatic phrases and response scales. linguistic equivalents had to be found for expressions such as “being (or becoming) housebound” and “social activities”. the notions of “discomfort”/“distress” did not have direct equivalents in some languages where a single notion had to be used. in most languages the frequency scale expressed in amounts of time had to be simplified to establish equidis- tant responses. conclusions: a rigorous translation methodology was performed to ensure conceptual equiv- alence and acceptability of translations. international feedback obtained through the translation process re- vealed issues regarding the original instrument, indicating that future amendments to the original may be necessary. future psychometric testing will be conducted to ensure reliability and validity of each translation, appropriate- ness of the questionnaire in each country and compara- bility of data across countries. pmt assessing physician practice profitability using an activity based costing model stephens jm, bell cf, klingman d parexel international, outcomes research group, alexandria, va, usa physicians are increasingly challenged to maintain prac- tice profits in the face of tightening reimbursements from payers. while office visits generate a revenue stream for physicians, it is not clear whether frequent lower com- plexity visits (e.g., nurse visits to administer injections) are actually profitable for physician practices. objec- tive: to develop an adaptable model and methodology to evaluate profitability and financial incentives for vari- ous in-office services provided by physicians and their staff. methods: a literature and expert opinion based model was developed from the physician practice per- spective and was designed to be flexible for a variety of office-based services. the practice cost component of the model was developed using activity-based costing princi- ples and included direct (drug acquisition, supplies, clini- cal labor time, office visits) and indirect (malpractice in- surance, office rent) expenses. the practice revenue component of the model consisted of the reimbursement amount from payers, including: drug reimbursement; of- fice visits for physician evaluation, injections, end of treatment follow-up and adverse events; and laboratory tests. results: practice profitability is inversely pro- portional to the number of low complexity office visits per year. payer mix is also an important determinant of profitability for in-office services, with medicare reim- bursements generally resulting in a net loss for practices (� loss per office visit for the lowest complexity ser- vices) and typical managed care reimbursements provid- ing only small profits (approximately per low complex- ity visit). conclusions: frequent low-complexity office visits for administration of drug therapies do not appear profitable for physician practices under medicare reimbursement. alternative modes of drug delivery such as implantable drug delivery devices or patient self-ad- ministration may be more profitable for physician prac- tices by allowing substitution of more highly reimbursed office services. pmt valuing non-workplace productivity lost in migraineurs: human capital approach and replacement cost method kim ss, lofland jh office of health policy and clinical outcomes at thomas jefferson university hospital, philadelphia, pa, usa objective: to determine the non-workplace produc- tivity costs (nwpc) for migraineurs using the human capital approach (hca) and replacement cost method (rcm). method: this was a supplemental analysis to a prospective, observational migraine outcomes study conducted at a managed care organization. migraineurs self-reported their work status, occupational category, number of days missed from normal ‘activities’ outside of paid job(s) due to migraine symptoms, number of days performing normal ‘activities’ with migraine symptoms, and percent effectiveness while performing normal ‘activ- ities’ with migraine symptoms, at baseline, months, and months after the initiation of sumatriptan. daily occu- pational wages were obtained from the bureau of labor statistics. nwpc were calculated using

and a lab coat. if you ask a group of adolescents how many have looked through a microscope, few raise their hands. if you discuss the implications of genetic research with a group of high school students, they’re likely to cut your next class. the reason why these students have such profound stereotypes of scientists and are less than enthusiastic about science’s impact on society is simple—the lack of exposure they receive during their pre-college education. according to a preliminary study conducted at leicester university in england, students are often repeatedly confronted with stereotypes of science and scientists via television, cartoon, and comic book characters as well as uninformed adults or peers (mcduffi e ). a university set in a major city has the resources to change the mindset of urban students and engage them in the exciting fi eld of science. at thomas jefferson university (tju), located in philadelphia, pennsylvania, a team of scientists and educators has developed a program that breaks down the stereotypes of the science fi eld and allows students to engage in real, live experiments at their own schools. why are such programs necessary? around the world, educators face diffi cult choices in focusing educational goals with limited resources. in the united states, the no child left behind act, which guides school funding policy, currently places an emphasis on literacy and math in schools, with the result that best programs and practices in education are increasingly directed toward these two areas. unfortunately, science education has become a lesser priority. teachers are not given adequate resources to allow students to “get their hands dirty” during science lessons. if we want a society that is interested and knowledgeable about the need for scientifi c research, the basic principles of the life sciences need to be integrated early in the pre- college curriculum (sylwester ). we developed the thomas jefferson university science outreach program (tjusop) to address this key issue and provide inquiry-based educational strategies through collaborative efforts between the university’s faculty and partnering school districts. how are we making a difference? using the tju facilities and laboratories, this innovative program integrates life science into the education of students between the ages of eight and eighteen from pennsylvania, new jersey, and delaware. the mission of the october | volume | issue | e | e open access, freely available online community page breaking down the stereotypes of science by recruiting

doi: . /journal.pbio. plos biology | www.plosbiology.org october | volume | issue | e tjusop is to foster an enthusiasm for science education, promote interest in future participation in biology- related fi elds, and allow all students the opportunity to learn life science through a hands-on, student-centered approach to instruction. the program is a supplement to the established curriculum, developed to support the content knowledge that is taught at each grade level. teachers are invited to attend a professional development workshop held at the beginning of the school year where they receive training and resources for the units. then, tjusop educators assist the teachers and students in their own classroom in running a weeklong experiment. this allows a large amount of group work to be completed simultaneously, even when teachers are faced with time constraints and large class sizes. this program is at no cost to the districts participating and is funded through the jefferson medical college and the kimmel cancer center, as well as through the generosity of several local and national groups including glaxo smith kline, the christopher ludwick foundation, the joan and joseph fernandez family foundation, the brook j. lenfest foundation, the foerderer foundation, drinker biddle and reath, and the pennsylvania department of agriculture. since its inception in august of , this program has reached over , students and teachers through our one-week zebrafi sh classroom experiments, our hands- on zebrafi sh and drosophila facility tours in conjunction with dr. james jaynes (a drosophila scientist at the kimmel cancer center), and our high school mentorship program held each summer. one of the main goals of tjusop is to reach students from ethnic and economic groups that are underrepresented in the scientifi c community. we have successfully partnered with the school district of philadelphia, where . % of the students come from ethnic backgrounds other than northern european and % of the students are eligible for free or reduced-cost meals. this district, among many others, receives pre- and post-instruction for all teachers and students at no cost to the district, allowing it to improve the quality of its science education. although we target these school districts, it is important to note that the us is facing a problematic decrease in the number of americans, of any background, entering the science and engineering workforce. according to a national science foundation report, “if action is not taken now to change these trends, we could reach and fi nd that the ability of u.s. research and education institutions to regenerate has been damaged and that their preeminence has been lost to other areas of the world” (national science board committee ). in regard to this unsettling discovery, tjusop welcomes all districts to participate and hopes to secure funding to double the number of students reached per year. anyone can be a scientist our pedagogical approach to experiments allows students and teachers to become scientists, following the scientifi c process from beginning to end. our live, one- week classroom experiments for the fourth, seventh, and tenth grades use zebrafi sh, a popular model organism for genetic research. a curriculum sample is as follows: in the seventh-grade unit, the students mate albino (recessive trait) male and a wild-type (dominant trait) female zebrafi sh in order to observe what the offspring will look like. students form hypotheses, such as that the young offspring will look

important to learn about science using zebrafi sh and the microscope, the student wrote, “i think it is important because we can fi nd facts about oursefs [sic].” this sounds like a good start. for

writing grants to twenty-three scholars and writers from the u.s. and around the world. the grants, totaling al- most $ , , are intended to sup- port these individual scholars studying issues of peace and inter- national cooperation. the research and writing grants, which are part of the foundation's program on peace and international cooperation, are designed to en- courage analysts to explore interna- tional issues and to seek out inno- vative approaches to new policy dilemmas emerging in the rapidly changing world arena. the grants are open to individuals of any na- tionality who have a proven ability to do creative work; recipients have included scholars, journalists, and practitioners, among others. the grants range up to $ , for individuals or $ , for a two-person team, and extend up to eighteen months in duration. recip- ients may carry out research at the institution or location of their choice. there are no age, academic affiliation, or geographic restric- tions on recipients. the purpose of the grants is to serve the following goals: • to broaden and strengthen the community of scholars and writ- ers engaged in policy-oriented work on international peace and security. • to encourage the reconceptual- ization of security issues in light of changing international events, and to encourage attention to new developments that have not been adequately understood as peace and security issues. • to foster integrated consideration of emerging relationships among economic, social, political, tech- nological, and environmental as- pects of global change. the twenty-three grant winners are: nancy barnes, maputo, mozam- bique anne f. bayefsky, university of ottawa ms. pascale m. combelles, blag- nac, france beth osborne daponte and timo- thy cote,

alpha award stephen horn, united states representative from california's th district and a political scien- tist with over thirty-five years of experience as a participant in na- tional policy making and service as a scholar, teacher, and university administrator, has received the na- tional capital area political sci- ence association pi sigma alpha award. the award, recog- nizing the outstanding contributions of a political scientist to public ser- vice, was presented march , , at mount vernon college. prior to his election to congress in , representative horn served as trustee professor of po- litical science at california univer- sity, long beach, with a specialty in the legislative process. congress- man horn's career began as a polit- ical appointee in the eisenhower administration, where he was ad- ministrative assistant to secretary of labor james p. mitchell. he then served for five years as legis- lative assistant to senator thomas h. kuchel of california, who at the time was deputy republican leader (whip) of the u.s. senate. during that time, he worked on major legislation, including the civil rights act of , the voting rights act of , medicare, and water policy for the western states. congressman horn has also been a senior fellow at the brookings institution and dean of graduate studies and research at the amer- ican university. from - , he served as president of california state university, long beach. in addition, he served part-time for sixteen years as a founding member and past chair of the national in- stitute of corrections of the u.s. department of justice, and for thir- teen years as a member and vice chair of the u.s. commission on civil rights. carrie chapman catt prize for research cheryl logan sparks, university of north carolina at chapel

philadelphia, lippincott williams & wilkins, ($ ). the second edition of gastrointestinal pathology is now available on cd-rom. the electronic ver- sion contains an expanded text and more illus- trations. it runs under windows or macintosh operating systems and requires at least mb of ram. i have run it on windows , , and nt. installation notes recommend setting virtual memory at mb or greater for optimal pictorial quality. a good rule of thumb is to set virtual memory at twice the amount of ram, but keep in mind that windows prefers to self-manage vir- tual memory for most applications. the produc- tion disk contains mb of data, with approx- imately % of the space devoted to pictures and diagrams. a combination of software products are bundled together to run this reference work. the vendors include folio corporation for text retrieval and iterated systems for image display. navigation around the disk is easy at the top level but awkward when paging through individ- ual chapters. there are shortcuts to individual topics via the go to option, but one needs to enter a numerical address. hyperlinks to pictures and illustrations allow you to overlay windows for side-by-side comparisons with the written text, and there is a clever pop-up option to view immediately any cited reference. an effective search engine that uses boolean logic is available for names or key words, and there are shortcuts to jump to your results. instructions on printing text items and exporting images are available in the read me files. overall, this disk contains sufficient tools to keep most users occupied for a long time. the text and illustrations have been revised for the second edition, and references are up- dated through (some through ). a se- lective review of dysplasia in ulcerative colitis shows it to be clear, concise, and complete. the recommendations for dysplasia-associated le- sions or masses are practical. the section on gastritis generally follows the sydney system with the usual caveats. however, i was disap- pointed not to find the article by dixon et al. concerning the updated principles and grad- ing data. a discussion of gastroesophageal reflux disease, -h acid testing, and short-segment barrett esophagus is lacking. gross photographs, radiographs, and diagrams are of excellent qual- ity. unfortunately, photomicrographs appear pixelated and rapidly degraded when zoomed. the combination of content, search capabil- ities, and the ability to print text and export images makes this cd a powerful reference work. the one disadvantage of this format is the quality of the photomicrographs. keeping in mind that the capacity of an ordinary -cent disk is mb and the availability of file compression tech- nology, one would think that medical publishers could produce higher quality microscopic im- ages. peter a. mccue thomas jefferson university philadelphia, pennsylvania modern pathology book review keloid pathogenesis:

(± . ). an average of % of study population was not adherent to their pd medications (mpr < . implies non-adherence). sensitivity analysis with mpr scores less than . , . , and . indicated an average of %, % and % were not adherent to their pd medications respectively. subjects adherent to their pd medications (mpr >= . ) had % less odds of experiencing pd symptom progres- sion (or = . ; ci: . – . ) compared to people not adher- ent to pd medications. all subjects with mpr < . experienced pd symptom progression. conclusion: high prevalence of non-adherence to pd medication and its association with pd symptom progression, irrespective of mpr threshold chosen, indicates it is a significant problem. there is a need for mecha- nisms to improve medication adherence in pd, namely improved patient understanding, simplified treatment regimens and improved tolerability profiles. pnd determinants of emergency department utilization for migraine care kwong wj university of georgia, athens, ga, usa objectives: over-utilization of emergency department (ed) services for non-urgent medical conditions has been noted as a problem for decades. headache is the sixth most common reason for ed visits. this study examined factors of ed use in a migraine population. methods: medical and rx claims of georgia medicaid beneficiaries who had at least one migraine medical claim (icd- of .xx) or one triptan/ergot claim between jan and dec , and were continuously eligi- ble from months before to months after first migraine claim were analyzed. subjects who had a narcotic claim and a medical claim for cancer (icd- – ), fractures ( – ), muscu- loskeletal and connective tissues disease ( – ), or sickle cell anemia ( . x) months before index date were excluded. likelihood of a migraine ed visit during the months after index date was estimated using logistic regression while con- trolling for age, gender, race, metropolitan status of county of residence, physician supply in county, butalbital and narcotic medication use months before index date. results: data from , subjects were analyzed. mean age was years (sd = ), % were male and % were caucasians. six percent of subjects had used butalbitals and % had used narcotics months before index date, and % subjects had at least one migraine ed visit months after index date. females, non-cau- casians, residents of metro counties or counties that had lower than average physician per , population ratio were more likely to have an ed visit (adjusted odds ratio, aor = . , . , . , and . respectively, p < . ). prior narcotic use signif- icantly increased the risk of ed visit (aor = . , p < . ). age and butalbital use had no effect on ed use. conclusion: local physician shortage and easy ed access encouraged ed use for non-urgent medical problems. improving access to primary care facilities is crucial for reducing non-urgent ed use. pnd developing a migraine quality of care measurement set leas b , gagne jj , goldfarb ni , rupnow mf , lofland jh , hopkins mm , nash d , silberstein sd thomas jefferson university, philadelphia, pa, usa, ortho-mcneil janssen scientific affairs, llc, titusville, nj, usa, thomas jefferson university hospital, philadelphia, pa, usa objectives: to develop a migraine quality of care measure- ment set at the health plan level, in order to begin measuring and improving migraine care processes and outcomes. methods: the measurement set was developed through: ) review of migraine care guidelines; ) literature review of quality mea- surement for migraine care; ) telephone interviews with thought leaders in migraine care and quality improvement; and ) assem- bly of a national advisory board consisting of prominent leaders within migraine care, quality measurement and managed care. the advisory board reviewed collected information from tasks – , discussed candidate measures, and established a consensus on target measures to be included in the set. results: the advi- sory board selected potential measures that could be imple- mented at the health plan level using administrative (claims) data. these measures capture information on: migraine diagno- sis and prevalence; use of preventive and therapeutic medica- tions; and, primary care, specialist, emergency, diagnostic radiologic, and inpatient service utilization. the measurement specifications have been developed to mirror technical specifica- tions for administrative measures in the health plan employer data and information set (hedis). conclusion: develop- ment of an evidence-based set of quality measures for migraine care is an important advance in seeking to measure and improve care for migraineurs. despite its prevalence, and impact on direct and indirect costs, migraine is not currently being addressed in the national quality measurement movement. the measurement set is now being pilot tested in health plans to assess feasibility of data collection, properties of the measures, and correlation among the measures. pnd understanding limitations of patient reported clinical outcomes in lupus wilke ct , jolly m , khandelwal s , rodby r , block ja ,

university of illinois at chicago, chicago, il, usa objectives: patient knowledge is associated with their ability to manage their disease (self-efficacy). the objective of this study was to examine the extent to which patients with systemic lupus erythematosus (sle) reported specific organs/system involvement that was consistent with medical records. methods: in a cross- sectional study, patients with sle were asked to indicate whether the following organ systems were affected by their lupus: skin/hair/scalp, joints, kidneys, brain, heart/lungs, (abnormal) blood counts, blood clots (including stroke). a retrospective chart review was undertaken to examine organ involvement and tests as recorded by their physician. exact and kappa measures of agreement between physician and

likely to have congestive heart failure, diabetes with chronic complications and bacteremia/septicemia. relative to the comparison group, patients with s. aureus csssis had significantly (p < . ) longer mean length of stay ( . vs. . days) and higher average costs per stay ($ , vs. $ , ). after con- trolling for potentially confounding factors, the excess mean costs associated with s. aureus

church, va, usa objectives: evaluate the incremental impact of s. aureus infection stays on hospital charges and length-of-stay in u.s. hospitals in . methods: the nationwide inpatient sample data were analyzed. hospital discharges were classified as either a s. aureus–related infection stay or a non-s. aureus- related infection stay using a combination of several icd- codes. incremental effect of s. aureus infection on hospital charges and length-of-stay was estimated using multivariate regression models adjusting for hospital fixed effects and patient variables including age, gender, race, payer, diagnosis-related grouping and concomitant conditions including diabetes, dialy- sis and lung disease. results: s. aureus infection was reported as a discharge diagnosis for . % of all hospital inpatients, or , stays, in . s. aureus infection hospital stays were significantly more likely among male, older patients, stays that were paid by medicare, white or non-hispanics and hospital stays among individuals with diabetes, lung disease or dialysis. after adjusting for covariates, the mean incremental impact of s. aureus infection on hospital charges and length-of-stay was $ , ( % confidence interval (ci): $ , –$ , ) and . days ( % ci: . – . ) among all inpatient stays, $ , ( % ci: $ , –$ , ) and . days ( % ci: . – . ) among surgical stays, $ , ( % ci: $ , –$ , ) and . days ( %

neurosurgical stays. conclusion: s. aureus infections present a considerable economic burden to u.s hospitals. based on the prevalence of s. aureus infection and its incremental impact, the total economic impact of s. aureus among all hospital admissions was estimated at $ . billion in u.s. dollars. pin determinants of total hospital costs among inpatients with candidemia lee sp , bunz t , gagne jj , maio v , goldfarb ni , horn dl , swanson r thomas jefferson univeristy, philadelphia, pa, usa, thomas jefferson university, philadelphia, pa, usa, pfizer inc, new york, ny, usa objectives: to identify factors associated with total hospital costs among patients with candidemia in a large, urban, tertiary care, teaching hospital. methods: this retrospective cohort study examined hospitalizations during calendar years and at thomas jefferson university hospital in philadelphia, pa, using data from various hospital systems. candidemia cases were identified via the microbiological laboratory information system as those patients with at least one confirmed positive blood culture for any candida species at any point during the study period. demographic, economic, and clinical data, includ- ing length-of-stay (los), payer types, total costs, and diagnosis related group (drg) assignments were collected from the hos- pital cost accounting system. pharmacy data (i.e. medications administered and associated costs) were retrieved from the phar- macy electronic information system. a multivariate regression analysis, using the natural logarithm of total hospitalization costs as the dependent variable, was conducted. independent variables included demographic information, relative drg weights, and candida species. results: among , total hospitalizations during the study period, cases were con- firmed positive for candidemia. the mean age of cases was years, % were female, and % were caucasian. the mean los was . days and the average inpatient cost for candidemia cases was $ , (sd = $ , ; median, $ , ). the most common candida species was c. albicans (n = ; %). the most commonly used antifungal treatment was fluconazole (n = , %). age, and relative drg weights (p < . ) were significantly positively correlated with total hospital costs. older patients with higher relative drg weights were associated with the higher total costs. race, gender, and marital status were not associated with total costs. conclusion: relative drg weights, as well as age are associated with total hospital costs among patients with candidemia. candidemia is expensive to treat and results in lengthy hospital stay. early detection and treatment may significantly reduce resource use as well as improve outcomes. pin the economic impact of

south korea, korea institute for health and social affairs, seoul, south korea objectives: the objective of this study is to examine the eco- nomic outcome of methicillin resistance in staphylococcus aureus bacteremia in korea, where mrsa is endemic in major- ity of hospitals. methods: we conducted retrospective case- control study of patients admitted to three university-based teaching hospitals in seoul, korea in . cases were defined as patients with methicillin-resistant s. aureus (mrsa) bac- teremia and controls were methicillin- susceptible s. aureus (mssa) bacteremia selected according to a priori matching cri- teria. cases and controls were identified. hospital charges were collected from hospitals’ billing system. results: the median hospital charge after the development of bacteremia was higher for cases with mrsa bacteremia ($ ) than for con- trols with mssa bacteremia ($ ). the median hospital a abstracts charge for pharmaceuticals of mrsa bacteremia patients was $ and that of mssa bacteremia patients was $ . the median length of hospitalization after the development of mrsa patients who survived was . days and that of mssa bac- teremia control patients who survived was days. conclu- sion: antibiotic resistance in staphylococcus aureus bacteremia increased direct medical cost by %. the results of this study indicate that the mrsa infection is associated with increased medical cost and prolonged hospital stay. pin direct costs of anemia among patients treated with zidovudine curkendall s , doan qv , everhard f , richardson j , emons mf cerner, vienna, va, usa, cerner, beverly hills, ca, usa, gilead sciences, foster city, ca, usa objectives: zidovudine (zdv) use has been shown to be associated with anemia. our objective was to assess the impact of anemia on medical resource use and cost in patients treated with a zdv-containing haart regimens. methods: case- control study using hiv insight, which contains medical chart data from us hiv care centers. zdv-naïve patients who began a zdv-containing haart regimen on any date from january to june were assessed for baseline anemia (hb < g/dl). those without anemia (n = ) were followed through june, or until they had anemia or changed to a non-zdv-containing regimen. those with anemia (n = ) were followed until anemia worsened (drop ≥ . g/dl). patients with an incident anemia event (initiating or worsening) with ≥ months of follow-up were selected as cases. controls were matched on baseline anemia, cd < , gender and time period. medical resource use was tabulated during the -year post anemia period. costs were estimated for health care encoun- ters using external data for prices expressed in $us. results: cases included patients with anemia ( initiat- ing, worsening.) cases had greater use of medical resources than controls: . vs . (p < . ) office visits per year, % vs % hospitalized (p < . ), % vs % treated with epo (p = . ) and % vs % (p = . ) with a transfusion. cases had higher average annual costs than controls; $ , vs $ , (p = . ). cost components included epo $ , vs $ (p = . ), antiretrovirals $ , vs $ , (p = . ), other drugs $ , vs $ , (p = . ) and hospital stays, $ , vs $ (p < . ). conclusion: patients treated with zdv who experienced anemia required significantly more medical care and reported higher medical cost than patients without anemia. pin impact of hiv and hcv co-infection on hospitalization and resource use among hemophilia enrollees in commercial health plans tencer t , friedman h , li-mcleod j , johnson ka university of southern california, los angeles, ca, usa, analytic solutions, llc, new york, ny, usa, baxter bioscience, westlake village, ca, usa objectives: determine the economic impact and resource uti- lization of adult hiv and hcv co-infected hemophilia patients in a managed care population in the united states. methods: retrospective claims database analysis from / to / . patients continuously enrolled for at least months and > years of age were included. hemophilia patients were identified using icd- cm, hcpcs, and ndc codes. four cohorts for analysis were established: hemophilia only hemophilia + hiv, hemophilia + hcv, hemophilia + hiv + hcv. the main out- comes of study were costs associated with all pharmacy and medical claims, inpatient hospitalizations (frequency and length of stay) and office visit distribution by physician specialty. results: annual cost of care was $ , for the hemophilia only cohort, $ , for the hiv cohort, $ , for the hcv cohort and $ , for hiv/hcv co-infected cohort in dollars. clotting factor accounted for approximately – % of total costs. the hemophilia only, hcv, hiv, hiv/hcv infected hemophilia cohorts had prescription drug costs of $ , , $ , , $ , and $ , , respectively. approximately % of hemophilia only, % of hcv, and % of the hiv/hcv cohorts were hospitalized during the study period (p = . ). hospitalizations that were hemophilia related accounted for % of total hospitalizations for the hemophilia only cohort and % for the hiv/hcv cohort (p = . ). no significant differ- ence in inpatient length of stay was found. there was a differ- ence in the mean number of office visits among the cohorts (p = . ) with the hiv/hcv cohort having more visits than the hemophilia only group, . vs. . , respectively (p = . ). conclusion: although we were not able to control for sever- ity, the presence of hiv and hcv co-infection in hemophiliacs is associated with an increase in annual costs by up to %. increased clotting factor use and prescription drug costs in the virally infected groups account for most of the increase in costs. pin using decision simulation model to evaluate the cost effectiveness of entecavir compared to adefovir therapy in lamivudine refractory chronic hepatitis b

estimate the long-term health and economic impact of managing chb with entecavir instead of adefovir treatment in the us, based upon projected clinical benefits from hbv dna reduction observed in trials. methods: we took the perspective of a comprehensive payer responsible for all direct health care expenditures. a decision simulation model was developed to consider a hypothetical cohort of lamivudine refractory chb patients. multivariate-adjusted relative risks for five hbv dna categories were derived from the published r.e.v.e.a.l.-hbv study. these results were applied to the patients with simulation of their hbv dna data derived from summary statistics reported in separate entecavir and adefovir clinical trials. entecavir and adefovir daily costs were assumed $ . and $ . based on the wholesale acquisition prices. life expectancy estimates, direct medical cost of and utility scores for different phases of chb were estimated from pub- lished us specific data. viral resistance due to treatment was included. results: entecavir was superior to adefovir for the mean reduction in serum hbv dna by pcr assay (log copies/ml) adjusted for lamivudine effect, with reductions of . versus . , respectively. more patients reached unde- tectable viral load level with entecavir than adefovir treatment at week ( . % vs . %). in the reference case, for patients aged years, compared with adefovir, ten years of ente- cavir treatment avoided compensated cirrhosis, decompen- sated cirrhosis, and hcc, resulting in . quality-adjusted life year (qaly) gain at an incremental cost of $

approach invites the reader to consider what a productive relationship between literature and history might look like—an urgent ques- tion for the inevitably interdisciplinary field of caribbean studies. as a literary scholar, i admire and appreciate ocasio’s deft management of archival sources, though i am curious as to what he thinks about the relationship between the costumbrista articles he analyzes and the antislavery costumbrista fiction that scholars agree occupied a central place in the nineteenth-century cuban lettered sphere. for example, what light do little-known texts such as suárez y romero’s colección de artículos or villaverde’s costumbrista article shed on those authors’ canonical antislavery novels francisco ( ) and cecilia valdés ( )—both of which feature costumbrista types such as the black coachman and the tragic mulata that ocasio discusses in his book? this comment does not, however, detract from the value of ocasio’s multidisciplinary project, which elucidates a world in which reluctant creole and mixed-race writers struggle with both the shadow of their own prejudices and the iron fist of the colonial censor in order to set the bases of what would become cuba’s hybrid national culture. to his credit, ocasio refuses to judge the costumbristas, instead allowing their works to speak for them- selves. such a subtly nuanced study at times strains the reader’s ability to follow, but the book is well worth the effort. —thomas genova tillet, salamishah. sites of slavery: citizenship and racial democracy in the post-civil rights imagination. durham, nc: duke up, . in sites of slavery: citizenship and racial democracy in the post-civil rights imagination, salamishah tillet explores the way in which post-civil rights african americans return to “sites of slavery”—”the objects, texts, figures, places and narratives from the american past that provide tangible links between present-day americans and american chattel slavery”—in order to produce a “democratic aesthetic” which responds to the “civic es- trangement” of contemporary african american citizenship in the united states ( ). tillet defines “civic estrangement” as “the paradox post-civil rights african americans experience as simultaneous citizens and ‘non-citizens’” ( ). her notion of a “democratic aesthetic” both emerges and departs from michael bennett’s democratic discourses in drawing on the du boisian “twoness” of “the pessimism of civic estrangement and the privilege of american legal citizenship” ( ). ultimately, tillet’s argument is that “the recognition of slavery in the civic sphere [achieved by returning, as the figures in tillet’s book do, to sites of slavery,] will expand the parameters of african american citizenship” ( ). tillet weaves through a rich archive of cultural productions from literary fiction and legal cases to photography and film. as such, the book’s interdisciplinary approach draws on scholarship in literary and cultural studies, performance studies, history, and law, and will appeal to readers from a variety of disciplines. c a l l a l o o following a teachable introduction, chapter , “freedom in a bondsmaid’s arms,” combs the historical canon’s account of the sexual relationship between thomas jefferson and sally hemings. tillet begins with barbara chase-riboud’s novel sally hemings, which imagines a romantic relationship that “does not entertain the possibility that jefferson sexually exploited hemings” ( ). while it isn’t fully clear how the novel considers what saidiya hartman describes as slavery’s “condition of unredressed injury” ( )—despite tillet’s gloss of the “ambiguity” of the relationship—it is clear that it repositions black female subjectivity as central to american founding narratives. chapter then moves to historian and law professor annette gordon-reed’s books thomas jefferson and sally hemings: an american controversy ( ) and the hemingses of monticello: an american family ( ) as well as playwright robbie mccauley’s drama sally’s rape. tillet reads gordon-reed’s books both as illustrating african american civic estrangement’s roots in american slavery and as “democratizing the historical record” ( ). in contrast to chase-riboud and gordon-reed, who both imagine a romantic relationship between hemings and jefferson, mccauley’s play directly confronts the violence of interracial sexual relationships during slavery and posits them as “the historical foundation for racial inequalities, such as civic estrangement, in the present” ( ). also unlike the previous two authors, mccauley highlights a multiplicity of african american women’s voices as opposed to privileging one particular subject. such a multiplicity “reconstructs a lineage of critical patriotism that centers black women’s dissent” ( ). the author’s second chapter, “the milder and more amusing phases of slavery,” looks at how post-civil rights african american writers and artists return to uncle tom’s cabin not to reject its most problematic characters, uncle tom and topsy, but to reclaim them “as post-civil rights symbols of racial resistance or reconciliation” ( ). tillet pairs ishmael reed’s novel flight to canada ( ) and robert alexander’s play i ain’t your uncle: the new jack revisionist “uncle tom’s cabin” ( ) to examine the promise and limits of satire as they each displace harriet beecher stowe’s narrative authority and “recast tom as a figure who embodies the racial self-awareness and political pessimism of the post-civil rights era” ( ). her reading of flight to canada demonstrates the multi-directional reach of satire, as reed critiques not only stowe’s racism but also the black power movement, while her reading of i ain’t your uncle highlights the importance of returning to sites of slavery because this reveals an account that “originates modern-day police brutality in american racial slavery” ( ). the chapter then moves to the utopian vision of bill t. jones’s dance last supper at uncle tom’s cabin/the promised land ( ) before closing with an analysis of kara walker’s silhouette the end of uncle tom and the grand allegorical tableau of eva in heaven ( ). jones’s dance begins by satirizing stowe through gross exaggeration, but differs from reed and alexander in not satirizing tom. instead, he “stages a coup de theatre” in which the beating of tom is reversed ( ). jones’s dance, tillet argues, returns to a site of slavery to resurrect tom in order to reinstate the histories of dead enslaved african americans into national memory. this allows for the culmination of the play with scores of naked dancers performing a democratic aesthetic which “underscores the brutality of slavery while simultaneously positing democracy as beyond representation but nonetheless desir- able” ( ). the chapter closes by shifting focus from tom to topsy in walker’s silhouette, which opens up space for thinking about reparations in conjunction with revenge and c a l l a l o o re-foregrounds black female corporeality as central to african american counter-memory and critical patriotism. chapter , “a race of angels,” turns to african american “heritage tourism” to slave forts on the west coast of africa—most specifically the house of slaves at gorée island, senegal, and cape coast castle at cape coast, ghana. tillet pushes to consider the contra- dictions she sees in heritage tourism: the clash of desires of african americans to imagine a transnational diasporic identity and also to see these slave forts as sites of an american past which thus offer ways of entering into us national belonging. as a result, “heritage tourism to the slave forts often produces a visual rhetoric that results in a displacement of contemporary ghana and senegal” ( ). she reaches this conclusion through exam- ining the “visual rhetoric” of two photographers’ portrayals of the slave forts—chester higgins’s the door of no return in the house of the slaves ( ) and carrie mae weems’s elmina cape coast ile de goree ( )—and one filmmaker’s use of a slave fort as a narrative catalyst—haile gerima’s film sankofa ( ). the final chapter, “what have we done to weigh so little on their scale?” adds signifi- cantly to legal and historical scholarship of the “long history” of reparations in the united states by emphasizing “the pivotal role that aesthetics have always played within debates about reparations for slavery and racial equality” ( ). tillet offers generous readings of the lawsuits cato v. united states ( ) and re african-american slave descendants litigation ( ), randall robinson’s the debt: what america owes to blacks ( ), and mary frances berry’s my face is black is true ( ) in synthesizing her arguments that contemporary reparations movements are situated “within the broader post-civil rights movement to reclaim sites of slavery and reimagine democracy” and that “symbolic changes must be accompanied by a structural transformation of the american economy” ( , ). sites of slavery then brings the reader back to the connection between slavery and the presidency with an epilogue on the president’s house in philadelphia. while tillet’s book is already remarkably interdisciplinary, i was left wondering what might happen if the combination of history, literary studies, and performance theory had been pushed just a bit further. for example, in chapter she cites joseph roach’s concept of “surrogation,” but merely to describe the phenomena of present-day bodies standing in for past bodies. what might come from thinking not only about present bodies within sites of slavery, but also thinking about the sites themselves through the performance studies concepts of “ephemerality”—since in visiting a slave fort in one is not, in fact, visit- ing a “slave fort” as it was in the eighteenth century—and “remains”—since in visiting a slave fort in , one may indeed feel overwhelmed by the connection to a history one never personally lived? how might sites of slavery both accomplish and forestall the task of crossing temporal boundaries as the living speak with the dead? this is to take nothing away from the richness of tillet’s book. sites of slavery offers fresh vocabulary for thinking through the very old problem of african american civic estrangement, contributes to the growing bodies of scholarship resituating black women as central to long histories of art and activism, and adds aesthetic dimensions to arguments about what responsibilities remain in a modern economic world full of spaces still visibly haunted by the specters of the massive enslavement that made it possible. —jesse a. goldberg c a l l a l o o note . for example, see phelan on

fear of french negroes: transcolonial collaboration in the revolutionary americas. berkeley: u of california p, . the title of the book, the fear of french negroes, is an oft-mentioned expression in contem- porary accounts of the haitian revolution; the phrase draws attention both to the fears felt by blacks themselves and the implied anxiety of their oppressors (xx). with an emphasis of what the author has termed “transcolonial exchange,” the book uses various case studies to examine “the migration of people, ideas, and practices across colonial boundaries from s to the s” (xx). on one hand, sarah johnson stresses the importance of seeing the “french negroes” of revolutionary haiti “as subjects rather than objects and as the agents of radical change in hemispheric economic and social relations” (xxi). on the other hand, she argues that the transcolonial collaborations and relations between hemispheric blacks to contest the racialized violence endemic to european imperialism and creole-nation building projects were disparate and “not intrinsically emancipatory or progressive . . . their struggle to connect was where a hopeful politics existed, sometimes even thrived” ( ). the term “transcoloniality” (or “transcolonial”) denotes both “a set of strategic practices in the late eighteenth and early nineteenth centuries and a methodological approach in the present to reconstruct how people understood and experienced their worlds” ( ). chapter is an analysis of the proslavery dimensions of transcolonial encounters. it provides the context to understand the master/slave dividing binary, a vital phenomenon that explains conflicting inter-americanist visions. the author analyzes the colonial ex- perience between inter-island blacks by linking seminal events in colonial cuba, jamaica, and territorial florida with revolutionary events in saint-domingue. she observes that transcolonial and inter-american relations and alliances were used decisively for vicious and repressive objectives. the reader should remember that the slave system in the ameri- cas was a “veritable state of war,” as the author highlights, between opposing factions: masters, and men and women who were forced to work as slaves. it is from this perspec- tive that johnson demonstrates how colonial powers (uniting across frontiers)—french, british, spanish, and north-american slave-holding societies—collaborated and used warfare techniques such as canine torture (i.e. “bred dogs” trained by chasseurs) in the circum-caribbean to terrorize african slaves, feed upon black flesh, and subdue non-white researchers knock down gene to stop hiv in its tracks researchers knock down gene to stop hiv in its tracks last month, san francisco officials granted a city proclamation to gero hütter for his discovery that a bone marrow transplant could, it seems, cure a person of hiv. the german hematologist’s findings raised hopes for a new therapeutic treatment, but the shortage of tissue-matched donors has prompted some researchers to apply the lessons learned to new techniques. the hiv-resistant bone marrow donor in hütter’s study carried a rare mutation in the gene encoding c-c chemokine receptor type , or ccr , a surface protein essential for helping hiv attach and infect healthy cells (n. engl. j. med. , – , ). the absence of this molecular portal makes infection nearly impossible. however, individuals with the ccr mutation are rare, and their bone marrow is not always a good match for all recipients. to emulate the protection of this mutation, several research teams are devising ways to downregulate the expression of ccr so that hiv does not recognize and invade sensitive cells in susceptible individuals. one line of attack involves rna interference. last month, for example, irvin chen and his colleagues at the university of california–los angeles school of medicine reported that short hairpin rna could successfully knock down ccr expression in human induced pluripotent stem cells (hum. gene ther. doi: . /hum. . , ). chen, backed by a $ million grant from the california institute for regenerative medicine (cirm), has now partnered with the tuscon, arizona–based biotech startup calimmune to develop therapies based on the approach. another strategy takes advantage of a newly developed technology based on zinc finger nucleases. with this approach, pioneered by sangamo biosciences of richmond, california, engineered enzymes make precise cuts in the genome to disrupt gene function. in , carl june’s team at the university of pennsylvania in philadelphia used zinc finger nucleases to disrupt ccr expression in human t cells, which they injected into hiv-infected mice. the gene therapy lowered viral loads and increased t cell counts in the mice (nat. biotech. , – , ). sangamo, in collaboration with june, has since started extracting mature t cells from hiv-positive individuals, knocking down expression of the ccr gene with zinc fingers, and then re-infusing the cells back into the blood. preliminary results from their first patient indicate that the modified cells are tolerated and persist at stable levels. mighty marrow the t cell approach, however, offers only a treatment—not a cure. so other researchers are focusing instead on altering bone marrow stem cells to provide an everlasting resistance to hiv. last year, cirm funded a team led by john zaia at the city of hope in duarte, california, in collaboration with sangamo, to start pursuing preclinical research applying the same gene therapy tactic in bone marrow. jerome zack of the university of california- los angeles aids institute notes that bone marrow stem cell therapy has the advantage of potentially lasting a lifetime, unlike gene therapy aimed at t cells, which must be repeated over and over again after the mature immune cells die out. what’s more, says zack, who is not involved in these studies, bone marrow transplants should help achieve higher cell counts. “we do not lack ways to attack hiv,” says david strayer, a virologist at thomas jefferson university in philadelphia. “we lack ways to deliver genes adequately.” a potential obstacle to ccr -based gene therapy is that the protein is not the only receptor recognized by the virus—some viral strains bind the cxcr chemokine receptor instead. so june and his colleagues are also developing zinc finger nucleases that target cxcr . however, some scientists have increased concerns about this approach’s safety, because the receptor may have an important role in healthy cells to attract white blood cells to sites of inflammation or injury. “the problem is that [cxcr ] may be more important to the cell for its normal functions than ccr ,” says ramesh akkina, who studies hiv gene therapy at colorado state university in fort collins. what’s more, even strains that normally rely on ccr can evolve to use cxcr instead. instead of focusing solely on these receptors, zaia also recently completed a phase trial of an hiv gene therapy technique involving three genes—two that interfere with viral replication and one that blocks ccr . reporting last month, zaia’s team showed that patients with aids-related lymphoma expressed the modified genes in their blood and showed no signs of short-term toxicity (sci. trans. med. , ra ). gene therapy against hiv “is now within the realm of feasibility,” says zaia. “now we can design larger studies and figure out ways to improve it.” janelle weaver, san francisco n e w s nature

been important in the structural evolution and evolutionary suc- cess of both birds and mammals. greater endurance capabilities are conferred directly by greater maximal metabolic rates, which vary between species. these maximal rates are known for many mammals but have not been determined for birds. we have mea- sured oxygen consumption in a large flight- less bird, the rhea, rhea americana, while it was running on an inclined treadmill, and find an upper limit to aerobic metabolism that is times greater than the minimum resting rate, a factorial increase exceeding that reported for nearly all mammals. we trained two female rheas (average mass . kilograms) for two years to run on a treadmill while wearing clear plastic hoods. we then measured linear increases in rates of oxygen uptake while the birds ran up a ° incline. the maximum rate of oxygen uptake was . millilitres per kilo- gram of body mass per second, reached at a running speed of . metres per second. there were no further increases in oxygen uptake when running speeds were increased to . metres per second, and plasma lactate concentrations indicated an increasing reliance on anaerobic glycolysis to provide metabolic energy at these higher speeds. rates of lactate accumulation ( . to . mm min ) and peak concentrations ( . mm) matched values reported for mam- mals running at speeds above their aerobic maximum. remarkably, the aerobic scope (the maximum aerobic metabolic rate divided by the minimum resting rate ) of these relatively inactive birds is more than . times those of typical mammals , and equals those of some of the most capable mammalian endurance runners (fig. ). although the rheas’ factorial increase in anaerobic metabolism is . times greater than the highest previously reported avian values (fig. ), we believe that their aerobic scope is representative of birds in general. previous avian values do not provide evi- dence of being upper limits; they are proba- bly below species’ maxima, but to unknown extents. nonetheless, the minimum meta- bolic increase required for flight of times the resting value exceeds the aerobic power of a typical mammal by a factor of . , and most avian species can fly. even birds with more limited endurance, such as the pen- guin and domestic fowl, can increase their aerobic metabolism by as much as a typical mammal , . we suggest that, on average, the aerobic scope of birds exceeds those of mammals by a factor of two or more. the structural basis of the rheas’ aero- bic power indicates that respiratory structure–function relationships, previously undetermined for birds, are quantitatively similar to those of mammals throughout most of the respiratory system, and are consistent with the concept of reasonable animal design (table ). rheas, like aerobic mammals, achieve maximal high rates of oxygen uptake with existing cardiovascular and muscular structures, rather than by scientific correspondence nature | vol |

paternity case the dna analysis of y-chromosome haplo- types used by foster et al. to evaluate thomas jefferson’s alleged paternity of eston hemings jefferson, the last child of his slave sally hemings, is impressive. how- ever, the authors did not consider all the data at hand in interpreting their results. no mention was made of thomas jeffer- son’s brother randolph ( – ), or of his five sons , . sons of sally hemings con- ceived by randolph (or by one of his sons) would produce a y-chromosome analysis identical to that described by foster et al. further collaborative data (for example, the whereabouts of any of those who might have been involved at conception) are needed to confirm that jefferson did indeed father his slave’s last child, as claimed in the title. we know thomas jefferson was there, but how about randolph jefferson and his sons? david m. abbey health science center, university of colorado, teakwood court, fort collins, colorado , usa e-mail: dabbey @aol.com if the data of foster et al. are accurate, then any male ancestor in thomas jefferson’s line, white or black, could have fathered eston hemings. plantations were inbred communities, and the mixing of racial types was probably common. as slave families were passed as property to the owner’s off- spring along with land and other property, it is possible that thomas jefferson’s father, grandfather or paternal uncles fathered a male slave whose line later impregnated another slave, in this case sally hemings. sally herself was a light mulatto, known even at that time to be thomas jefferson’s wife’s half sister , . gary davis evanston hospital, ridge avenue, evanston, illinois , usa foster et al. reply — it is true that men of randolph jefferson’s family could have fathered sally hemings’ later children. space constraints prevented us from expanding on alternative interpretations of our dna analysis, including the interesting one proposed by davis. the title assigned to our study was misleading in that it repre- sented only the simplest explanation of our molecular findings: namely, that thomas jefferson, rather than one of the carr broth- ers, was likely to have been the father of eston hemings jefferson. it had been suggested to us earlier (by herbert barger, who also helped to recruit the descendants of field jefferson who par- ticipated in our study) that isham jefferson, son of thomas jefferson’s brother ran- dolph, might have been the father of one or more of sally hemings’ children. barger’s proposal was based on a statement that isham was reared by thomas jefferson; he suggested that isham could have been at monticello or at snowden (snowden was across the james river from scottsville, which is about miles from monticello) when eston hemings was conceived. but it is not known for certain that isham was at monticello at that time, whereas it is docu- mented that thomas jefferson was. from the historical knowledge we have, we can- not conclude that isham, or any other member of the jefferson family, was as likely as thomas jefferson to have fathered eston hemings. we know from the historical and the dna data that thomas jefferson can neither be definitely excluded nor solely implicated in the paternity of illegitimate children with his slave sally hemings. when we embarked on this study, we knew that the results could not be conclusive, but we hoped to obtain some objective data that would tilt the weight of evidence in one direction or another. we think we have provided such data and that the modest, probabilistic interpretations we have made are tenable at present. e. a. foster*, m. a. jobling†, p. g. taylor†, p. donnelly‡, p. de knijff§, r. mieremet§, t. zerjal¶, c. tyler-smith¶ * gildersleeve wood,

muscles are similar to those of mammals of the same size and aerobic capacity, whereas those in the relatively inactive flight muscles are only half as large and correspond to values reported for less aerobic mammals (table ). given that % of the rhea’s body mass consists of leg musculature, rates of oxygen uptake by mitochondria per millilitre dur- ing locomotion at the aerobic maximum appear to fall within the range reported for mammals. capillary densities in the rhea leg and flight muscles, like the mitochon- drial volume densities, also parallel values reported for the muscles of athletic and less mobile mammals. in contrast to the apparent conservation of structure–function relationships in most of the respiratory system, our results sug- gest that there are basic differences in the performance of the lungs of birds and mammals. we could not measure the lung volumes of the rheas directly, but in birds these are normally slightly more than half of those of mammals of the same mass , . the rheas therefore achieved maximum oxygen flux rates, equal to those of the most aerobic mammals of their size, using lungs that are probably only half as large. this supports the general belief that avian lungs provide relatively more function per unit volume than mammalian lungs , . although the aerobic limits of rheas and athletic mammals are similar, the metabolic power available in practice, and their func- tional needs, are not. unlike dogs, horses and other athletic mammals that sustain high metabolic rates for hours during pre- dation and migration, rheas do little or no sustained running and are poor at dissipat- ing metabolic heat loads . rheas have apparently not been under strong selective pressures like those that promoted the aero- bic power of extant running mammals. large flightless birds lead fairly inactive lives, and may have lost the ability to fly primarily because of a lack of predation. why rheas have an aerobic power that greatly exceeds their apparent functional needs remains a puzzle. matthew w. bundle*, hans hoppeler†, ruth vock†, june m. tester*, peter g. weyand* *museum of comparative zoology, harvard university, bedford, massachusetts

crosslinking offers potential to improve suture pullout in rotator cuff repair: an ex vivo sheep study joseph a. abboud md where are we now? r otator cuff disease in patients older than years of age remains both common and therapeutically challenging. various forms of treatment, both nonoperative and operative, have been extensively explored. no single solution has emerged as dominant, and none is curative. in the hope of changing that, biologics in rotator cuff surgery have become something of a hot topic, as surgical success may be more depen- dent upon biologic healing than on the technical aspects of tendon fixation. the current authors set out to use an exogenous collagen crosslinking agent, genipin, to augment tendon repairs. the use of this agent to augment tendon healing has not been explored before. the study, conducted in a cadaveric (ex vivo) sheep model, allows us to make two conclusions pertaining to suture pullout strength: ( ) pullout strength is enhanced after tendon incu- bation in genipin for hours when utilizing the simple suture configuration repair technique, and ( ) incubation of the tendon in genipin for or hours did not make a difference in the pullout strength of tendons repaired using a modified mason-allen suture configuration. this suggests that the suture configuration may be the most important aspect of this repair model as opposed to the exposure to the exoge- nous crosslinking agent genipin. where do we need to go? what we really need to know is whether genipin has any real clinical utility. in other words, can we use genipin in humans with rotator cuff tears? does its mode of activation lend itself to uti- lization in vivo at the time of surgery? will its method of delivery allow for safe and effective clinical treatment in a timely fashion? will this provide any clinically enhanced levels of healing after surgical repair? while this study does not allow us to answer any of these questions, as a proof-of-concept effort, it paves the way for future studies that should be able to do so. how do we get there? future in-vivo rotator cuff animal studies in rats or sheep utilizing this this corr insights is a commentary on

ga, usa objectives: over-utilization of emergency department (ed) services for non-urgent medical conditions has been noted as a problem for decades. headache is the sixth most common reason for ed visits. this study examined factors of ed use in a migraine population. methods: medical and rx claims of georgia medicaid beneficiaries who had at least one migraine medical claim (icd- of .xx) or one triptan/ergot claim between jan and dec , and were continuously eligi- ble from months before to months after first migraine claim were analyzed. subjects who had a narcotic claim and a medical claim for cancer (icd- – ), fractures ( – ), muscu- loskeletal and connective tissues disease ( – ), or sickle cell anemia ( . x) months before index date were excluded. likelihood of a migraine ed visit during the months after index date was estimated using logistic regression while con- trolling for age, gender, race, metropolitan status of county of residence, physician supply in county, butalbital and narcotic medication use months before index date. results: data from , subjects were analyzed. mean age was years (sd = ), % were male and % were caucasians. six percent of subjects had used butalbitals and % had used narcotics months before index date, and % subjects had at least one migraine ed visit months after index date. females, non-cau- casians, residents of metro counties or counties that had lower than average physician per , population ratio were more likely to have an ed visit (adjusted odds ratio, aor = . , . , . , and . respectively, p < . ). prior narcotic use signif- icantly increased the risk of ed visit (aor = . , p < . ). age and butalbital use had no effect on ed use. conclusion: local physician shortage and easy ed access encouraged ed use for non-urgent medical problems. improving access to primary care facilities is crucial for reducing non-urgent ed use. pnd developing a migraine quality of care measurement set leas b , gagne jj , goldfarb ni , rupnow mf , lofland jh , hopkins mm , nash d , silberstein sd thomas jefferson university, philadelphia, pa, usa, ortho-mcneil janssen scientific affairs, llc, titusville, nj, usa, thomas jefferson university hospital, philadelphia, pa, usa objectives: to develop a migraine quality of care measure- ment set at the health plan level, in order to begin measuring and improving migraine care processes and outcomes. methods: the measurement set was developed through: ) review of migraine care guidelines; ) literature review of quality mea- surement for migraine care; ) telephone interviews with thought leaders in migraine care and quality improvement; and ) assem- bly of a national advisory board consisting of prominent leaders within migraine care, quality measurement and managed care. the advisory board reviewed collected information from tasks – , discussed candidate measures, and established a consensus on target measures to be included in the set. results: the advi- sory board selected potential measures that could be imple- mented at the health plan level using administrative (claims) data. these measures capture information on: migraine diagno- sis and prevalence; use of preventive and therapeutic medica- tions; and, primary care, specialist, emergency, diagnostic radiologic, and inpatient service utilization. the measurement specifications have been developed to mirror technical specifica- tions for administrative measures in the health plan employer data and information set (hedis). conclusion: develop- ment of an evidence-based set of quality measures for migraine care is an important advance in seeking to measure and improve care for migraineurs. despite its prevalence, and impact on direct and indirect costs, migraine is not currently being addressed in the national quality measurement movement. the measurement set is now being pilot tested in health plans to assess feasibility of data collection, properties of the measures, and correlation among the measures. pnd understanding limitations of patient reported clinical outcomes in lupus wilke ct , jolly m , khandelwal s , rodby r , block ja ,

university of illinois at chicago, chicago, il, usa objectives: patient knowledge is associated with their ability to manage their disease (self-efficacy). the objective of this study was to examine the extent to which patients with systemic lupus erythematosus (sle) reported specific organs/system involvement that was consistent with medical records. methods: in a cross- sectional study, patients with sle were asked to indicate whether the following organ systems were affected by their lupus: skin/hair/scalp, joints, kidneys, brain, heart/lungs, (abnormal) blood counts, blood clots (including stroke). a retrospective chart review was undertaken to examine organ involvement and tests as recorded by their physician. exact and kappa measures of agreement between physician and patient report were calculated for each organ system. results: the patient sample (n = ) hp relationship of direct-to-consumer advertising spending and drug pricing for the top twenty drugs from to :

(p = . ) or a prescription (p < . ) for a medication. conclusion: clinicians are amenable to patients asking for drug information and medications, but their level of receptiveness is associated with the source from which the patient’s questions originate. hp relationship of direct-to-consumer advertising spending and drug pricing for the top twenty drugs from to : an exploratory study parthan ag, anantharaman rt, shepherd md the university of texas at austin, austin, tx, usa there exists an ongoing debate regarding the effect of direct-to-consumer (dtc) advertising spending on drug prices. the two opposite views are: (a) increase in dtc advertising spending would be added to drug prices (b) dtc advertising would increase competition and thus reduce drug prices. objective: explore the relationship of dtc advertis- ing spending and drug pricing for the top twenty drugs from to . methods: top twenty drugs were selected on the basis of their dtc advertising spending (source: competitive media reporting, ny) for . for analysis, average wholesale price (awp) per unit was used from the blue book awp unit pricing. for each of the top twenty drugs, the following trend graphs were plotted for to : (a) the total dtc advertising spending and per unit price of the drug; (b) the percent changes in the dtc advertis- ing spending and drug price. the percent change in dtc advertising spending and drug price for a year was calculated as percent change from the previous year. results: only sildenafil (viagra) and sibutramine (meridia) showed an increase in the actual drug price with an increase in the dtc advertising spending. however, for these two drugs in year , the percent change in dtc advertising spending decreased and the percent change in drug price increased. no trend was evident from the graphs of the other eighteen drugs. on an average dtc advertising spending for most of the drugs decreased with time while drug prices continued to increase. conclusion: results indicate a very weak relation- ship between dtc advertising spending and drug prices. the increase in drug price in spite of the decrease in the dtc advertising spending contradicts both rationale i.e. dtc advertising spending reduces drug price through competition or increase in drug price is due to increase in dtc advertising spending. hp impact of direct to consumer advertising—the consumer search for information belazi dt , crawford a , pizzi l thomas jefferson university & abbott laboratories, philadelphia, pa, usa; thomas jefferson university, philadelphia, pa, usa objective: the purpose of this study is to identify factors associated with consumers’ seeking various infor- mation sources about medications sought in response to direct to consumer advertising. methods: in the spring and summer of , the fda, division of drug marketing, advertising, and commu- nication conducted a national telephone survey of adults regarding direct-to-consumer (dtc) promotion of prescription drugs and its effects on visits to the doctor. in addition to consumer attitudes, opinions and responses to direct to consumer advertising, the survey also elicited responses regarding consumer utilization of information sources such as reference books, -telelphone number, and health care providers. there were total respon- dents, of whom completed the required questions regarding information sources. chi square analysis was used to assess associations between consumer demographic information and the different types of informational resources that consumers used after exposure of direct to consumer advertising. results: the analysis showed significant associations (p £ . ) between gender, race, education, health status, self-perceived knowledge of health, prescription medication use, and internet use and many of the following information resources: reference books, asking friends/neighbors, -telephone number, primary doctor, pharmacist, specialist, and nurse. across all information sources, female gender, decreased health status, low education, and higher than average medica- tion use were the variables that had the strongest associ- ations. a model was developed depicting the associations between these findings. results pertaining to specific sources will be presented. conclusions: this study evaluated how different consumers seek information from different sources as a result of direct to consumer advertising. this study will assist those interested in identifying and further educat- ing consumers about their health and novel treatments or therapies. hp fda regulatory actions against misleading or unsubstantiated economic and quality-of-life claims: an analysis of warning letters and notices of violation stewart ka, neumann pj harvard school of public health, boston, ma, usa doi: . /j.bpj. . . monday, february , a the c terminus of milton is an important regulator of the mitochondria

philadelphia, pa, usa, boston university, boston, ma, usa. emerging evidence shows the importance of genes controlling mitochondrial fusion in physiology and their deregulation in neurodegenerative and metabolic disorders. however, apart from djm, the biophysical properties of the fusion- competent mitochondria remain elusive. to evaluate the conditions of contact formation and fusion, we used organelle-targeted fluorescent proteins, includ- ing photoactivatable gfp, which allow tracking of individual mitochondria. in h c cells, almost every mitochondrion is aligned with microtubules that pro- vide the primary tracks for mitochondrial movement. our results show that ~ % of fusion events involve moving mitochondria. however, fusion occurs irrespective of mitochondrial speed. furthermore, ~ % of fusion events in- volve the tip portion of the mitochondrion, whereas only ~ % of these events involve organelle side. nocodazol, a microtubule disrupting agent that inhibits mitochondrial movements decreases the fusion frequency and changes mito- chondrial fusion sites. strikingly, - % of the physical contacts between ad- jacent mitochondria did not result in fusion events. to evaluate whether the fu- sion efficacy depends on the spacing between the outer and inner mitochondrial membranes we used drugs that alter the matrix volume. valinomycin, a k þ ion- ophore that induces matrix swelling evoked a decrease in mitochondrial motil- ity leading to fewer contacts among mitochondria but the number of fusion events was maintained, indicating an increase in fusion efficacy. this change occurred at a low valinomycin concentration ( . nm) that did not affect djm or opa cleavage. nigericin ( . mm), a k þ /h þ ionophore that induces shrinkage of the matrix elicited fusion inhibition and mitochondrial aggrega- tion. importantly, no motility inhibition or opa cleavage occurred at the same time and the djm was increased. these results suggest that mitochon- drial fusion is facilitated by mitochondrial motility, the key determinant of the inter-mitochondrial encounter numbers and preferentially involves the front-tip of the moving organelle. in addition, fusion efficacy depends on the mitochondrial matrix volume. -pos mitochondrial fusion dynamics in human skeletal muscle-derived cells veronica eisner, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. mitochondria have a fundamental role in both muscle physiology and pathol- ogy. mitochondrial fusion and fission are important for energy metabolism, calcium homeostasis and cell death. however, the mechanisms underlying mitochondrial dynamics are poorly understood, especially in physiological models such as skeletal muscle. here we evaluated mitochondrial fusion dy- namics in human skeletal muscle cells (husmc). skeletal muscle satellite cells were isolated from human muscle biopsies and were maintained and dif- ferentiated in cell culture. mitochondrial fusion events were evaluated by con- focal imaging of cells expressing mitochondria matrix targeted dsred and matrix targeted or outer mitochondrial membrane (omm) targeted photoacti- vatable-gfp. when we tagged the mitochondria in ~ % of total cellular area with photoactivated-gfp, we found those mitochondria undergoing matrix fusion with a frequency of . . events/min/cell (n= ). among the fusion events, % led to complete fusion and only % was followed by separation at the apparent fusion site within to seconds. both complete and transient fusion events resulted mostly from longitudinal mergers, involving end to end interaction or from mergers of adjacent mitochondria in side to side orien- tation. furthermore, we found that omm and matrix fusion are sequential and separable steps, displaying . seconds gap (n= ). finally, we evaluated the mitochondrial fusion dynamics in husmc derived from both normal and malignant hyperthermia susceptible individuals. at resting state, no significant differences were found in the number of events or in their characteristics. thus, mitochondrial fusion commonly occurs in husmc, and enables mixing of both soluble and integral membrane factors. this process would help to maintain the stability of mitochondrial metabolism. the relatively low frequency of the tran- sient fusion is probably due to the parallel organization of the cytoskeletal tracks for mitochondria and to the limited mitochondrial motility. -pos imaging interorganelle contacts and local calcium dynamics at the er-mitochondrial interface györgy csordás , péter várnai , tünde golenár , swati roy , george purkins , tamás balla , györgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary, national institutes of child health and human development, bethesda, md, usa. the local coupling between er and mitochondria is essential for proper cell function. a main role of the er-mitochondrial junctions is to provide a local calcium signaling domain that is important both for keeping energy production in line with demand and for the control of apoptotic mechanisms. so far it has not been possible to visualize the tiny er-mitochondrial contact points in living cells or to monitor the localized [ca þ] changes in the narrow space between er and mitochondria ([ca þ]er-mt). here, we exploited rapamycin-mediated heterodimerization of fkbp and frb domains of fluorescent protein constructs respectively targeted to the outer mitochondrial membrane and the er as drug-inducible inter-organelle linkers to identify er-mitochondrial contacts and to measure the [ca þ ]er-mt. high- resolution fluorescence imaging and d reconstruction revealed rapamycin-in- duced clustering of the er-targeted fluorescent linker-half to the contact areas with the mitochondria without major changes in the spatial arrangement of the er. essentially all mitochondria displayed contacts with the er in both rbl- h and h c cells. plasma membrane-mitochondrial contacts were less frequent with er stacks being inserted between the two organelles. single mitochondria display discrete patches of er contacts as well as continuous as- sociations. cytoplasmic and mitochondrial matrix [ca þ] showed robust er-mitochondrial ca þ transfer with considerable heterogeneity even among adjacent mitochondria. pericam-containing linkers revealed ip -induced [ca þ ]er-mt signals that were resistant to buffering bulk cytosolic [ca þ ]c in- creases and exceeded um. the largest [ca þ ]er-mt signals did not occur at the tightest associations, indicating space requirements for the ca þ transfer machinery and functional diversity among er-mitochondrial junctions. these studies provide direct evidence for the existence of high ca þ microdo- mains between the er and mitochondria in living cells, and open new possibil- ities to probe the functional importance of this specialized compartment. -pos dependence of er-mitochondria calcium transfer on different ip receptor isoforms tunde golenar , szava bansaghi , gyorgy csordas , david i. yule , suresh k. joseph , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, university of rochester medical center, rochester, ny, usa. ip receptors (ip rs) release ca þ from the er, which is locally relayed to the mitochondria to control several aspects of mitochondrial function. recent stud- ies have suggested that type ip rs (ip r ) are particularly important for me- diating the ca þ transfer at the er-mitochondrial interface. we set out to sys- tematically evaluate the respective role of each ip r isoform in chicken dt cell lines that express only one ip r isoform (double-knockout, dko , dko and dko ) or provide a null-background (triple-knockout, tko) for analysis of mammalian ip rs and their mutants. simultaneous imaging of cytoplasmic and mitochondrial matrix [ca þ] ([ca þ]c and [ca þ]m) was performed in either permeabilized cells chal- lenged with ip or in muscarinic receptor overexpressing intact cells stimulated with carbachol (cch), an ip -linked agonist. saturating ip evoked complete discharge of er calcium and resulted in comparable [ca þ]m increases in each dko. furthermore, the cch-induced [ca þ]c spike was closely followed by a [ca þ]m rise in each dko. when tko cells were rescued with rat ip r or ip r , the latter mediated a larger [ca þ]c transient but the [ca þ]m increases were very similar for both isoforms. the relationship between the [ca þ]c peak and the corresponding [ca þ]m response was also very similar for ip r and ip r . to assess the impact of the release kinetic through ip r in the mitochondrial ca þ transfer we used two point mutants of the ip r , which display either enhanced inhibition by ca þ (d n) or are relatively insensitive to ca þ inhibition (d n). d n showed dampened [ca þ]m signal and [ca þ]m vs. [ca þ]c relationship, whereas d n displayed a steeper [ca þ]m vs. [ca þ]c relationship than the wild type ip r . thus, each ip r isoform can support local er-mitochondrial ca þ transfer and their competence to activate mitochondrial ca þ uptake depends on their deactiva- tion kinetic. biophysical properties of mitochondria undergoing fusion mitochondrial fusion dynamics in human skeletal muscle-derived cells imaging interorganelle contacts and local calcium dynamics at the er-mitochondrial interface dependence of er-mitochondria calcium transfer on different ip receptor isoforms objective(s): diversity among health care providers is

bonheiden, belgium sponsored by rabih a. chaer, md objective(s): the belgian-italian trial investigating abbott vascular vascular iliac stents in the treatment of tasc a, b, c and d iliac lesions (bravissimo) study is a prospective, nonrandomized, multicenter trial, conducted at belgian hospitals and italian hospitals. the objective is to evaluate the long-term ( -month) outcome of the self-expanding nitinol absolute pro (abbott vascular) and the balloon-expandable omnilink elite (abbott vascular) stent in transatlantic intersociety concensus (tasc) a and b and tasc c and d iliac lesions. a separate analysis of both patient populations is performed. methods: primary study end point is primary patency at months, defined as a target lesion without a hemodynamically significant stenosis (� %, systolic velocity ratio � . ) on duplex ultrasound imaging and without target lesion revascularization (tlr) � months. the study included patients, of which presented with tasc a or b lesions and with tasc c or d lesions. analysis is performed comparing the results of the tasc a/b cohort with the results of the tasc c/d cohort. results: the study included patients with tasc a, with tasc b, with tasc c, and with tasc d aortoiliac lesions. demographic data were comparable for all tasc patient groups. of the tasc a patients, received omnilink elite stents, received absolute pro stents, and one received both stents. of the tasc b patients, received omnilink elite stents, received absolute pro stents, and mixed stent use was reported in two patients. in the tasc c group, patients were treated with onmilink elite, with absolute pro, and six with both stents. of the tasc d patients, received the omnilink elite, received the absolute pro, and received both. the -month primary patency rates were uniformly high, without statistically significant differences among tasc groups: a, %; b, %; c, %; and d, %. stratified by stent use, -month primary patency rates were % for self-expanding stents, % for balloon-expandable stents, and % for the patients treated with both types (p � . ). conclusion: primary endovascular treatment of symptomatic iliac artery occlusive disease produces -month patency � % irrespective of tasc classification. on the basis of these findings, endovascular therapy should be considered the treatment of choice for this condition; primary aortofemoral bypass is no longer indicated for isolated iliac artery occlusive disease. evolving treatment of popliteal artery aneurysm patrick a. stone, md, ali aburahma, md, priyanka jagannath, kim- ball knackstedt, do, stephanie thompson, phd, john campell, md, albeir mousa, md, james campbell, md . west virginia university and charleston area medical center, charleston, wva objective(s): during the past decade, the treatment of popliteal aneu- rysms has evolved at our institution from the sole operative intervention during the initial part of the study period, to combined surgical and endovascular treatment, and finally, to endovascular-centered management in more recent years. outcomes among treatment modalities for popliteal aneurysms were assessed. methods: this is a retrospective review of all patients with popliteal aneurysms treated at our institution from to . data collection included the indication for intervention, treatment details, interventional patency, limb salvage, perioperative outcome, and long-term survival. results: during this period, aneurysms were treated in patients. indications for intervention included ( %) with symptomatic presentations, and ( %) were asymptomatic. treatment included endovascular exclusion in , surgical repair in ( posterior approach and medial approach with bypass and exclusion), and primary amputation in one patient. nine aneurysms ( . %) received catheter-directed thrombolysis (fig). demographics were similar between the two treatment cohorts, except for age, with endovascular stenting patients significantly older ( . vs . years, p � . ). the mean length of stay was . vs . days (p � . ), favoring endovascular treatment. there were no perioperative ( -day) deaths in the endovascular group and one death in the surgical cohort. the mean patency follow-up was . vs . months. primary patency did not differ between endovascular and surgically treated patients at year ( . % vs . %, p � . ) and years ( . % vs . %, p � . ). no limbs were lost in the endovascular group during the follow-up period of . months. one late limb loss occurred in the surgical cohort (mean follow-up, . months). the long-term survival rate was % in the endovas- cular patients (mean follow up, . months) and . % in the surgical patients (mean follow up, . months, p � . ). conclusions: endovascular treatment of popliteal aneurysms provides similar short-term patency to that of the traditional gold standard approach fig. journal of vascular surgery september abstracts with surgical bypass, with shorter hospitalizations in symptomatic and asymptomatic patients. further long-term follow-up is required to compare these two treatment modalities for durability to determine the optimal popliteal aneurysm

objective(s): the goal was to create a multifactorial disease severity score (dss) for characterization of femoropopliteal arterial lesions. by having a greater understanding of the effect of patient comorbidities and an in-depth method to characterize an arterial lesion, we may be able to better compare lesions in different studies and predict which therapy is most appropriate for each lesion undergoing an endovascular intervention (evi). methods: we evaluated lesion and patient characteristics in our prospectively maintained lower extremity arterial lesion database from to to create a gradated dss. results: we identified femoropopliteal lesions in patients. statistical analysis by multivariable cox proportional hazards model identi- fied variables that impact patency: seven lesion characteristics (table i) and nine patient characteristics or comorbidities (table ii). factors with the most impact were a chronic total occlusion (dss ), lesion length � mm (dss ), and no runoff vessels and stenosis of % to % (dss ). the following factors were considered baseline, or score of : stenosis � %, lesion length � mm, and three-vessel runoff. by adding these variable scores, a dss was created and used to predict patency of the evi. conclusions: the presence of a chronic total occlusion, lesion length � mm, poor runoff, and the presence of congestive heart failure have the most dramatic effect on patency after evi. a compre- hensive dss allows for the in-depth classification of lesion characteristics and factors that predict success of evi and can allow for comparison of distinct lesions. future comparisons of effectiveness of treatment modal- ities can be possible. table i. significant femoropopliteal lesion characteristics that negatively impact patency after

usa, yeshiva university, new york, ny, usa, thomas jefferson university, philadelphia, pa, usa. the most likely targets for volatile anesthetics (va) are ion channels. the mechanism of volatile anesthetic action is not completely understood. identify- ing the molecular pathway for drug binding is crucial to understand the effect of va on voltage gated sodium channels. we use molecular dynamics simula- tions to identify the binding sites for a hydrophobic general anesthetic isoflur- ane, on voltage gated bacterial sodium channel nachbac. apart from the voltage sensing domain (s -s ), linker and the pore domain (s -s ), bacterial sodium channels also have fenestrations, which provide a hydrophobic tunnel through the lipid-embedded portion of the channel to the central cavity, where the known local anesthetic site is located. unbiased ‘‘flooding’’ simulations were performed on the activated open confirmation of nachbac. we per- formed a cluster analysis to identify all the possible binding sites of isoflurane. the three most important ones among them are: a region near the selectivity filter, called the extracellular site, a region near the s -s linker, called the linker site, and a region within the cavity, called the cavity site. the most important observation is that isoflurane enters the central cavity through the fenestrations. free energy perturbation method was employed to calculate the binding affinities of isoflurane for each of these sites. we also studied the interactions between isoflurane and the amino acids in these three binding sites. -pos board b a key gating charge interaction required for slow inactivation of the navab bacterial sodium channel tamer m. gamal el-din, todd scheuer, william a. catterall. university of washington, seattle, wa, usa. bacterial voltage-gated sodium (nav) channels are considered an ideal model for structure-function studies. the elucidation of the crystal structure of the bacterial channel navab (payandeh et al., nature , - , ) opened an avenue to understand electrical signaling in excitable cells at the structural level. navab expressed in hi insect cells as for structural studies has unusually negative voltage-dependent activation (va ~ mv). navab also has three phases of inactivation, a biphasic early inactivation process (t ~ ms, t ~ . s, at � mv) followed by an unusually strong and use-dependent slow-inactivation process. to search for the molecular basis for negative activation and slow inactivation of navab, we mutated the outer- most gating charge partner in the s segment, asn , to lys. this mutation shifted the activation curve ~ mv toward more positive potentials. surpris- ingly, it also completely abolished use-dependent slow inactivation. we showed previously that the equivalent residue in nachbac (asp ) interacts with the r gating charge in the s segment during activation using the disul- fide locking method (decaen et al, pnas ( ) - ). to test whether this interaction between r and n was critical for slow inactivation, we mutated navab r to cys. the resulting mutant navab_r c also had positively shifted channel activation (þ mv) and no use-dependent slow inactivation. the fact that these reciprocal mutations have the same functional effects suggests that interaction between r in the s segment and n in the s segment is an important link that stabilizes the activated state of the voltage sensor and triggers the slow inactivation process. -pos board b computational study of the prokaryotic sodium channel karen m. callahan, benoit roux. university of chicago, chicago, il, usa. ion-selective voltage-gated ion channels allow ions of a specific element or set of elements to pass, but exclude other ions. recently, the crystal structure of navab was published (payandeh et al ( ) nature , ), giving an un- ambiguous picture of the structure of the sodium channel selectivity filter (sf) of the prokaryote arcobacter butzleri. the filter is much wider than that of the narrow, carbonyl-lined potassium channels, allowing ions to penetrate with minimal dehydration, multiple pathways, and even to pass each other. previous computational studies have attempted to explain sodium selectivity, and claimed consensus (corry and thomas ( ) jacs , , furini and domene ( ) plos , e ). experimental ion selectivity determina- tion from pore-only constructs of a sodium channel with the same sf sequence shows stronger ion selectivity from reversal potential than from the ratio of the fluxes of sodium and potassium (shaya et al ( ) pnas , ), but selectivity, na þ/kþ, was still less than five. simulations based upon the closed-pore crystal structure could not determine selectivity directly from con- duction. to investigate this issue, we first calculated multi-ion potentials of mean force in the selectivity filter of pore-domain-only navab with an ex- tended equilibration period, and a replica-exchange molecular dynamics scheme, which allows for improved sampling. we then explored the non- equilibrium conduction of sodium and potassium in the presence of an applied electric field through a model navab pore truncated to mimic the conformation of the open pore. we also present multi-ion pmf calculations to illustrate similarities and differences between this model and the intact pore. when taken together, these two methods provide complementary views of ion selectivity and conduction based upon the conformation of the navab crystal structure of payandeh et al ( ). -pos board b volatile general anesthetic interactions with a bacterial sodium channel annika f. barber , srinivas g. raju , david lebard , vincenzo carnevale , michael l. klein , manuel covarrubias . thomas jefferson university, philadelphia, pa, usa, temple university, philadelphia, pa, usa. general anesthesia results from complex interactions involving ion channels in the brain. voltage-gated ion channels are modulated by halogenated inhaled general anesthetics, however the drug-channel interactions are generally believed to be non-specific making it difficult to investigate the molecular mechanisms of anesthetic action. we find, however, that the bacterial sodium channel nachbac exhibits differential regulation by different general anes- thetics, suggesting that there may be specific interactions. molecular dynamics (md) simulations have identified several possible binding sites for isoflurane in the nachbac channel structure. here, we have characterized the affinity, occu- pancy and hydrogen bonding for these sites and identified key interactions. in addition, experimental evidence suggests that both isoflurane and sevoflurane have dual actions on nachbac, possibly involving action at two different sites. consistent with pore block, sevoflurane accelerates the decay of the current ( % faster at . mm sevoflurane) but, at the same time, increases the peak current ( % increase with . mm sevoflurane), which argues against the blocking mechanism. we hypothesize that an additional mechanism involving a distinct site is necessary to explain the latter effect. we are currently employ- ing md simulation and structural modeling combined with mutagenesis and electrophysiology to test this two-site hypothesis and investigate the molecular mechanisms of these opposing effects. supported by

mcarthur , robert j. french . university of calgary, calgary, ab, canada, rmit, melbourne, australia. m-conotoxins (mctxs) are potent blockers of eukaryotic sodium channels, and individual members of the mctx family are highly specific for particular nav isoforms. we have begun to explore mctx interactions with nachbac, a pro- karyotic nav channel closely related to navab, whose crystal structure was re- cently determined (payandeh et al, , nature : ). our data reveal actions on both ion conduction and gating, consistent with polymodal actions on the pore domain. under voltage clamp, whole-cell currents from nachbac expressed in tsa- cells were reduced, up to nearly complete block, by concentrations in the pm to mm range, for wildtype toxins and derivatives of mctx piiia and kiiia. for wildtype piiia, dose-response data ( . - , nm) yielded the following: ic = . nm; maximal fraction of current blocked = . ; hill coefficient = . . chen & chung ( , biophys. j. : ) predicted an ic of . nm for piiia when the navab channel is occupied by sodium ions. even at very low [piiia] ( pm), the unblocked currents showed increasing rates of inactivation as the peptides were washed in, suggesting a gating mod- ulation, that was not tightly associated with pore block. for mctx piiia ( . nm), or kiiia ( nm), inactivation accelerated by ~ -fold. substitution of key basic residues (piiia-r a and kiiia-k a) reduced blocking potency and decreased the speeding of inactivation to less than -fold. given the remarkably high selectivity and affinity that mctxs show for certain eukaryotic nav channels with highly asymmetric pores, it may seem surprising that they bind to symmetric bacterial nav channels with such high affinity. binding of isoflurane to a bacterial

ability. this increase in permeability during necrosis is caused by the opening of a permeability transition pore - ptp in mitochondrial inner membrane. on the other hand apoptosis induces opening of a large non-selective channel (mito- chondrial apoptotic channel - mac) in the mitochondrial outer membrane. we used atomic force microscopy to study the structure and organization of native mitochondrial membranes isolated from necrotic and apoptotic cells. we com- plement our afm imaging with nanopatricle-based immnunoassays, where mi- tochondrial membranes are pretreated with nanoparticle-conjugated antibodies for recognition of specific proteins. we will present our data on morphological studies of these membranes and will discuss feasibility of this approach for visu- alization of mptp and mac channels in the native mitochondrial inner mem- branes (mim) and mitochondrial outer membranes (mom) using afm methods. -pos board b heterogeneity of cardiolipin regulation yi-fan lin, mei-jie jou. department of physiology and pharmacology, chang gung university, tao-yuan, taiwan. cardiolipin (cl), is a protective phospholipid located exclusively on the mito- chondrial inner membrane for stabilizing individual complex of mitochondrial respiratory chain for energy production, mitochondrial ca þ (mca þ) regula- tion and reactive oxygen spices formation. deficiency of cl has been associated with multiple mitochondrial dysfunctions upon pathological condition, diseases and aging. using fluorescence digital imaging microscopy this study investi- gated how cl is preciously regulated in rat brain astrocytes rba- . results demonstrate that at the resting stage, the distribution of cl is rather heteroge- neous within single cell. the perinulear mitochondria show lower cl than mi- tochondria from the peripheral area. heterogeneity of cl was observed even in single mitochondrion, which may affects mitochondrial fission and fusion mechanism. cl was found to be higher at the cross point area of mitochondrial network. thread-like mitochondria and granular-like mitochondria, however, contain similar level of cl. some of the thread-like mitochondria even contain lower cl than granular-like mitochondria. upon localized oxidative stress in- duced by nm laser irradiation, heterogeneous depletion of cl was observed among mitochondria populations within single cell. distribution of cl altered also mitochondrial dynamics that depletion of cl always occurred before fis- sion. intriguingly, although complete depletion of cl is irreversible upon high strength of laser irradiation, depleted cl recovered during lower strength of laser irradiation and occurred heterogeneously within mitochondria popula- tions. condensation of cl was observed upon various stresses including oxida- tive stress induced by nm laser irradiation, ionomycin-induced mca þ stress and arachidonic acid-induced lipid stress which crucially enhances pres- ervation of cl and its resistance to stress which may be of significance for mi- tochondrial protection and survival. unveiling pathophysiological regulation of cl thus may contribute significantly the prevention and treatment of cl asso- ciated pathological condition, diseases and aging. -pos board b mtdna t g mutation-induced mitochondrial complex v inhibition augments cardiolipin-dependent alterations of mitochondrial dynamics during oxidative, ca d and lipid insults in narp cybrids: a potential therapeutic target tsung-i peng , chia-wei hsiao , mei-jie jou . keelung chang gung memorial hospital, tao-yuan, taiwan, national tsing hua university, tao-yuan, taiwan, chang gung university, tao-yuan, taiwan. mitochondrial dynamics including morphological fission and mitochondrial movement are essential to normal mitochondrial and cellular physiology. this study investigated how mtdna t g (narp)-induced inhibition of mito- chondrial complex v altered mitochondrial dynamics in association with a pro- tective mitochondrial phospholipid, cardiolipin (cl), as a potential therapeutic target. narp cybrids harboring % of mtdna t g genes and its parental osteosarcoma b cells were studied for comparison, and protection provided by melatonin, a potent mitochondrial protector, was explored. we demonstrate for the first time that narp mutation significantly enhances apoptotic death as a result of three distinct lethal mitochondrial apoptotic insults including oxida- tive, ca þ and lipidstress. in addition, narpsignificantly augmented patholog- ical depletion of cl. narp-augmented depletion of cl results in enhanced retardation of mitochondrial movement and fission and later swelling of mito- chondria during all insults. these results suggest thatcl is a common and crucial pathological target formitochondrial apoptoticinsults. furthermore, cl possibly plays a central role in regulating mitochondrial dynamics that are associated with narp-augmented mitochondrial pathologies. intriguingly, melatonin, by differ- entially preserving cl during various stresses (oxidation > ca þ > lipid), res- cuesdifferentially cl-altered mitochondrial dynamics and cell death (oxidation > ca þ > lipid). thus, melatonin, in addition to being a mitochondrial antioxidant to antagonize mitochondrial oxidative stress, a mitochondrial permeability tran- sition modulator to antagonize mitochondrial ca þ stress, may stabilize directly cl to prevent its oxidization and/or depletion and, therefore, it exerts great po- tential in rescuing cl-dependent mitochondrial dynamics-associated mitochon- drial pathologies for treatment of narp-induced pathologies and diseases. -pos board b shuttling of membrane-bound cytochrome b between mitochondria and er david weaver , veronica eisner , peter varnai , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis medical university, budapest, hungary. cytochrome b type b has long been described as a tail-anchored protein of the outer mitochondrial membrane (cb -mito). using a fusion protein consisting of photoactivatable gfp fused to the c-terminus membrane-targeting segment of cb -mito, we have found that while this construct concentrates in the mitochon- drial membrane, it is continuously exchanged between the membranes of the mitochondrion and the endoplasmic reticulum. this effect does not depend on the presence of mitofusin or , as it occurs in mfn-null mefs as well as in wild type cells. interestingly, a point mutation in the hydrophobic, membrane-targeting sequence of cb -mito that was recently reported to prevent its association with autophagosome membranes, also eliminates its exchange with the er. while lipids and viral proteins have been shown to traffic from er to mitochondria, this is, to our knowledge, the first demonstration of such a back-and-forth shuttling, representing both a new aspect of the er- mitochondrial interface and an mfn-independent pathway for the exchange of an outer mitochondrial membrane protein. -pos board b dichotomy between mitochondrial ca d uptake and martix [ca d] in micu deficient cells tunde golenar , gyorgy csordas , fabiana perocchi , vamsi k. mootha , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, harvard medical school and massachusetts general hospital, boston, ma, usa. mitochondrial calcium uptake is central to cell physiology, but the underlying molecular mechanism remains elusive. recently, micu was identified as a mi- tochondrial protein required for ca þ uptake but dispensible for mitochondrial respiration or membrane potential generation. to study the specific role of micu in mitochondrial ca þ uptake, we used wild type hela cells (ctrl), micu knockdown by distinct shrnas (kd) and micu rescued cells (res- cue). first, we monitored the cytoplasmic and mitochondrial matrix [ca þ] ([ca þ]c and [ca þ]m, respectively) during store-operated ca þ entry. specif- ically, cells were preincubated in a ca þ-free buffer containing thapsigargin (tg), to deplete the er ca þ store, and then ca þ was added back and the en- suing [ca þ]c (fura ) and [ca þ]m (mitochondria-targeted pericams) changes were measured. in both ctrl and kd a [ca þ]c increase occurred that was asso- ciated with a [ca þ]m rise only in ctrl. the rescue behaved similarly to the ctrl. also, when ca þ was added to permeabilized cells, no [ca þ]m increase ap- peared in the kd. these results confirm that the shortage of micu causes sup- pression of the [ca þ]m signal. surprisingly, when the ca þ entry was followed byuncoupler additiontoreleasethemitochondrial ca þ content, ahuge[ca þ]c increase appeared in kd, however, when the uncoupler was added prior to ca þ entry, no [ca þ]c increase occurred. thus, mitochondria in the kd also accumu- lated ca þ during ca þ entry. mitochondrial ca þ uptake evoked by ca þ ad- dition was also documented in permeabilized kd by measurement of ruthenium red sensitive ca uptake and cytoplasmic ca þ clearance (fura ). thus, ca þ is accumulated by micu deficient mitochondria but it fails to result an increase in[ca þ]m.weare currentlyinvestigating, whether suppression ofthe [ca þ]m rise in the kd is due to enhanced matrix ca þ-buffering. -pos board b micu serves as a ca d-controlled gatekeeper for the mitochondrial ca d uniporter györgy csordás , tünde

and the distinguished careers of professors arenhövel, backe, drechsel, friedrich, kaiser, and walcher. we are all deeply aware of the extent to which the science we do builds on the achievements of those who have gone before us, and on the insights and hard work of our colleagues working in the field today. one of my very earliest memories as a scientist, dating from the days when i was a young graduate student, is that of attending “photonuclear physics boot camp” (otherwise known as the photonuclear gordon conference) and learning from (and with) many of those “retiring” today. thomas (walcher) was one of the very first scientists i ever knew beyond the boundaries of my own laboratory. he came to visit us (at yale), and i went and visited him and his colleagues at darmstadt. it has been a great plea- sure to follow his distinguished career in science, from low- q electron scattering to hadronic physics at cern and beyond, and finally to the leadership role he has played at mami for many years. hartmuth (arenhövel) has been the keeper of the flame of all knowledge about the deuteron, and a worthy succes- sor to gregory breit. you should know that i was a grad- uate student at yale, and it was one of professor breit’s missions in life to convince any and all who would listen that the deuteron was the essence of nuclear physics, and that until we understood the deuteron, we did not un- derstand anything. i think it is fair to call hartmuth the gregory breit of my generation; he has made so many contributions. a e-mail: cardman@jlab.org dieter (drechsel) has always been one of those peo- ple i have looked to as the source of the “big picture” in nuclear physics. he has provided us with deep insights, a sense of direction, and an understanding of what is really important. he has also been an inspiring example here at mainz of the tremendous benefits to everyone of having a close collaboration between theory and experiment. jörg (friedrich) has taught us all how to analyze and interpret electron scattering data with minimal prejudice (and, therefore, maximal honesty). it is a delight to see the same rigorous approach that was so successful in the study of nuclei and their excited states now being applied to nucleon structure. karl-heinz (kaiser) and his mentor, helmut herming- haus, taught the world how to build superb continuous- wave (cw) electron accelerators effectively and efficiently. karl-heinz, in particular, through the design and con- struction of the double-sided microtron, is leaving the in- stitute well positioned for another generation of superb experiments. in conclusion, on behalf of so many people i have worked with in nuclear physics, i want to thank each of you for your many contributions to our field, and to express the hope we all share that for each of you “retirement” is a formality, not a reality, and that you will continue to be active for years to come. research at jefferson laboratory the thomas jefferson national accelerator facility, also called jefferson lab (or jlab), operates the continu- ous electron beam accelerator facility (cebaf). ce- baf is a cw electron accelerator capable of delivering three electron beams for simultaneous experiments in the the european physical journal a three experimental areas. originally designed for gev, its present maximum energy is . gev. the cebaf user community consists of about physicists; more than half of them are actively involved in the experimental program. in addition to its main mis- sion, jlab contributes to the development and use of free electron lasers, to medical imaging, and to community outreach programs. the intellectual and technical foundations for the con- struction of cebaf were provided by the scientific suc- cesses of earlier electron accelerators (the generation that included saclay, mit-bates, nikhef, and, to some ex- tent, slac), and by the enhanced research opportunities provided by cw electron beams as demonstrated at fa- cilities such as mami. cebaf is a large, international laboratory with a broad research program; it has been in operation for some seven and a half year now. what are the goals of cebaf’s research program? ba- sically, we aim to understand strongly-interacting matter. how are the hadrons constructed from the quarks and glu- ons of qcd, and how does the nucleon-nucleon force arise from the strong interaction? we further aim to identify the limits of our understanding of nuclear structure by us- ing the high precision attainable with the electromagnetic probe and the possibiltiy of extending investigations to very small distance scales. a specific issue that motivated the construction of cebaf was our desire to gain insight into the question of where the description of nuclei based on nucleon and meson degrees-of-freedom fails and the un- derlying quark degrees-of-freedom must be taken into ac- count. one can ultimately characterize all of this as trying to understand qcd, not in the perturbative regime acces- sible at very high energies and very short distance scales, but in the strong interaction regime relevant to most of the visible matter in the universe. to make progress in these areas, there are other critical issues that must be addressed, such as the mechanism of confinement, the dy- namics of the quark interaction, and how chiral symmetry breaking occurs. to provides some shape and structure to the discussion of the experiments, the cebaf program can be organized into half a dozen broad thrusts. this presentation will concentrate on two of them: – how are the nucleons made from quarks and glue? – where are the limits of our understanding of nuclear structure how are the nucleons made from quarks and glue? among the most interesting puzzles in physics today are: why there is this effective degree-of-freedom in qcd, the nucleon; and how something as complicated as the resid- ual qcd interaction between quarks in nucleons can be characterized by a rather simple n-n potential? to pro- vide experimental insights that will help us solve the first of these puzzles, the jefferson lab research community has mounted

[ ]). due to two-photon exchange effects modifying the results. theoretical estimates suggest that the modifications are much smaller for the polarization transfer data than for the rosenbluth data, so the former are likely to be more directly interpretable in terms of the nucleon form factors. the electric form factor of the neutron has now been measured up to a q of . (gev/c) using polarization transfer techniques, and the data taken with different methods agree quite well. the theoretical interpretation of the data is summa- rized in fig. . the theories that describe the data reason- ably well reveal two key aspects of nucleon structure: the importance of the pion cloud, and the importance of in- corporating the relativistic motion of the quarks into the theoretical description of the nucleon. when one looks at these form factors in a phenomeno- logical way with minimum prejudice [ ], what emerges is some of the clearest evidence we have for the nucleon’s pion cloud (see fig. ). similar results have been obtained using a different approach to model-independent analy- sis [ ] of nucleon form factors. we plan to extend the proton form factor data to ∼ (gev/c) , where we may see evidence for a diffraction minimum. the neutron form factor will also be extended to ∼ (gev/c) . further extensions of a factor of two are planned with the gev upgrade. such extensions have . . . µ p g e . . . . bijker (vmd) holzwarth (soliton) hammer (vmd + disp. rel.) miller (rel. qcm + “bag”) . . . . . . f /f ∝ ln (q /Λ )/q p g m p g e n g m p µ p g d g m n µ n g d q (gev ) q (gev ) q (gev ) q (gev ) fig. . theoretical descriptions of the nucleon form factor data [ ]. historically proven to be important, and we expect these data will provide further insight and sensitivity for com- pleting our understanding of how to construct nucleons from quarks and gluons. the european physical journal a - . - . . . . . . . . . . . . . r · ρ ( r; g e p p o l ) / f m - r / fm π+ -b p p b p n total - . - . . . . . . . . . . . . . . r · ρ ( r; g e n ) / fm - r / fm π− b n p ( - b n )n total fig. . neutron radial charge distribution (top) and the polar- ization term contribution to the proton radial charge distribu- tion (bottom) as inferred from an analysis using phenomeno- logical models [ ] of the world nucleon form factor data. the green solid lines show the pion cloud contribution. note that r ρ(r) is plotted, emphasizing the distribution at large radii. the strange quark form factors have become an in- teresting area of study that is both analogous and com- plementary to the classical electromagnetic form factors. by using the weak component of the electro-weak interac- tion we access the weak neutral current form factor, which can be interpreted very elegantly in terms of the strange quark distribution. because there are no valence strange quarks, this measurement provides a unique window on the sea quark distribution. the strange form factors can also be expected to provide us with interesting experi- mental insights into nucleon structure: by combining the electromagnetic and the weak neutral current form factors we should be able to separate the spatial distribution of the u, d, and s quarks. figure shows the world’s data on the strange proton form factor taken at forward angles as a function of q . one sees data from the a experiment at mainz [ , , ], from happex i and ii (jlab hall a) [ , , ], and from g (jlab hall c) [ ]. these difficult experiments would be impossible without highly polarized electron beams from magnificently stable accelerators. the fact that the data from different laboratories lie roughly on a smooth curve gives one confidence that the experimenters are do- ing it right. the first thing that strikes you about the data is that the form factor is rather small. this is to be expected, as all of the strange quarks emerge as quark-antiquark pairs popping in and out of the vacuum, and to get a finite form factor there must be some kind of a polarizing effect a g happex fig. . nucleon strange form factor data from parity-violating electron scattering at forward angles as a function of q . - - . . e s g m s g sample with calculationag he (' ) happex- a g (extrapolated)happex-h (' ) % c.l. q = . gev leinweber et al.

(gev/c) we have data at both forward and backward scattering angles, so we can separate these effects (see fig. ). the data favor a positive value of gsm , which is at variance with most of the theoretical models. experiments are in progress that will reduce the size of the error ellipse at this q value by a about a factor of , and additional experiments planned at both mami and jlab will permit separations at other q values. a broad, world-wide effort will provide the results we want. another interesting experiment is the measurement of the pion form factor. the pion is the simplest qcd bound system, the “positronium” of qcd. one expects that the pion form factor will provide us with evidence for the l.s. cardman: physics at the thomas jefferson national accelerator facility . . . q (gev/c) q f π bse+dse qcd sum rule cqm perturbative qcd amendolia π+e elastics previous p(e,e’π + )n jlab f π - results jlab f π - results pre limin ary fig. . pion form factor data [ ]. transition of the strong interaction from the perturbative (qed-like) to the strong (confinement) regime at the low- est possible momentum transfer. these data also constrain phenomenological models of the pion. measuring the pion form factor is not simple. at low q , one can scatter pions off atomic electrons, but a bowl- ing ball does not transfer energy to a ping-pong ball effi- ciently, and even with very high energy pions this exper- iment cannot reach high momentum transfers. to reach higher momentum transfer in the absence of a free pion target, one must scatter electrons off virtual pions inside a proton and extrapolate the data to the pion pole. the world’s data (see fig. ) is beginning to distinguish be- tween different theoretical approaches. with the gev upgrade, we expect to extend the data out to a momen- tum transfer of (gev/c) and to be able to infer the distance scale for the onset of perturbative behavior. . what is the excited state spectrum of the hadrons? if one looks at several decades worth of data on nucleon resonances and tries to use a simple quark model to clas- sify the states in terms of the excitation in units of h̄ω and the angular momentum of the three quarks, the states that have been identified so far fit nicely into this scheme, but there are many states that have been predicted but have not been found. it is an interesting fact that one can explain all of the states that have been seen so far by assuming that the nucleon and its excited states are a diquark-quark system. since most of the data have been obtained from pion-induced reactions, and many of the missing states are predicted not to couple to pions, it is also possible that the missing states may have been over- looked for experimental reasons. in atomic spectroscopy the line spacing is large com- pared to the line width, and measuring the complete spectrum is relatively straightforward. in nucleon spec- troscopy, the strong interaction causes the width to be comparable to the spacing. identifying weak states and fig. . w-dependence of the scattered electron rate for the p(e, e′)x reaction. clas data taken at gev primary beam energy. the energies of the known excited states are shown in black, while those of the states “missing” in the simple quark model description are shown in red. extracting the internal quark structure from the measured cross sections is a difficult task. the problem can be seen easily in fig. , which shows the inclusive electron scatter- ing cross spectrum from the proton for a gev electron beam. with a modern electron accelerator and a large ac- ceptance detector one can obtain data on the transition form factors over a large q -range [ → (gev/c) ] in a single shot. there is plenty of cross section in the region where the missing states (shown in red) have been pre- dicted, but extracting their individual strengths from the data is a real challenge. the combination of cw electron beams and modern, large solid angle detectors provides important advantages for addressing this problem experimentally. if one looks at the same data set of fig. but uses the information on the energy and momentum of the final state proton mea- sured in coincidence with the inelastically scattered elec- tron, it is straightforward to infer the missing mass asso- ciated with the decay of the excited state (see fig. ). one can see clearly from the raw missing mass spectrum that the “missing” states do not couple to pions, but rather to the η and ω. with the further information on the an- gular correlations of those decay particles relative to the momentum transfer axis one finally has the information necessary to decompose the spectrum of fig. , and learn just what is there. this effort naturally begins with the ∆( ), which decays predominantly into pion and nucleon. figure shows a comparison of separated structure functions from clas data for the p(e,e′p)πo reaction with theoretical fits and results from previous experiments. the ∆ → γ∗n-transition is characterized by three mul- tipoles: the electric quadrupole e, the magnetic dipole m, and the scalar multipole s. as we examine this transi- tion as a function of momentum transfer we expect that different aspects of the excitation will become apparent. at large distance scales (corresponding to low momentum transfers) we should see the effect of the pion cloud, while at large momentum transfer (corresponding to short dis- tances) we will eventually reach the limit given by pqcd the european physical journal a n( ) n( ) ∆( ) w (g e v ) π η ω m x (gev) π thresh. m is s in g s ta te s fig. . w vs. missing-mass mx for the same clas data shown in fig.

oxide, and a peroxynitrite scavenger, uric acid. in particular, treatment with high doses of uric acid virtually prevented clinical symptoms of the disease. together with our demon- stration of the presence of activated macrophages expressing high levelsof inosandevidenceofperoxynitrite formation in brain tissue from patients with ms, these findings are of importance in the development of approaches to treat this disease. evidence for the activation of the enzyme (inos) responsible for the production of the free radical nitric oxide (no) in an immuneresponseand the releaseofnoin thecentralnervous systems (cns) of animals with experimental allergic enceph- alomyelitis (eae) or viral encephalomyelitis ( – ) has led to further study of the role of no and its products in cns pathology. convincing evidence for the involvement of no overproduction in the pathogenesis of eae comes from studies that have correlated spinal cord and brain no levels with clinical symptoms in animals with eae ( , ). the relevance of these animal studies to multiple sclerosis (ms) is emphasized by the fact that high levels of mrna specific for inoscanbeobserved inbrain lesions frommspatients ( , ). in this case, therehasasyetbeennoconsensusas to thenature of the inos-positive cells with either cells of the monocyte lineage or astrocytes being implicated by different studies ( , ).todeterminemore specifically thenatureandoriginof the activated cells expressing inos in the ms brain we have expanded our analysis of ms brain tissue specimens using a refined combination of immunohistochemistry and reverse transcriptase in situ pcr (rt-is-pcr). several possibilities exist regarding the nature of no in- volvement in the pathogenesis of cns lesions. a variety of destructive effects have been postulated, both through direct interaction with cell surface and internal molecules ( ) and through chemical interactions with oxygen species, such as superoxide (o ), to form other potentially more toxic inter- mediates ( , ). one of these, peroxynitrite (onoo ), the reaction product of no and superoxide, is a potent oxidant ( ), which can be formed in an inflammatory response and cancauseavarietyof toxiceffects, including lipidperoxidation ( ) and tyrosine nitration ( ). it has therefore been sug- gested that peroxynitrite may be responsible for a significant proportion of the damage attributed to no. thus, peroxyni- trite may be an important factor in the generation of cns lesions. indeed, in a previous study we found evidence of tyrosine nitration in the brain tissue of ms patients ( ). to further clarify the direct or indirect role of no and peroxyni- trite in thepathogenesisofcns lesions,weanalyzed theeffect of substances thought to inhibit inos activation or to selec- tively scavengenoorperoxynitriteon thedevelopmentof the clinical symptoms of eae in an acute model. materials and methods brain tissue specimens. brain tissue was obtained post mortem from patients who had suffered with ms for at least years.brain tissuewasremovedwithin hrofdeathduring autopsy at thomas jefferson university and areas with and withoutplaqueswere immediately frozenondry iceandstored at c until use. the diagnoses of ms, based on clinical presentation, were confirmed by the post mortem histopatho- logical examination of brain tissues. all ms brains were found to contain pathognomonic ms plaques. in most cases autopsy sampleswereof frontal lobes,whichprovidedmixedwhiteand gray matter. immunohistochemistry and rt-is-pcr. to define cell types positive for inos mrna expression in frozen brain sections, immunohistochemistry was performed in conjunc- tionwithrt-is-pcrasdescribed( , ).stainingwascarried out with a variety of antibodies and lectins: (i) cells of the macrophageymicroglia cell lineage were identified with rho- damine-conjugatedricinus communisagglutinin (rca- ) lec- tin (sigma), which specifically binds these cells ( ); (ii) the publication costs of this article were defrayed in part by page charge payment. this article must therefore be hereby marked ‘‘advertisement’’ in accordance with u.s.c. § solely to indicate this fact. copyright q by the national academy of sciences of the usa -

of cns resident or infiltrating cells demonstrated that cells expressing inos message also stained with rca- lectin, which selectively binds to cells of the monocyte lineage. stains for astrocytes, neurons, oligoden- drocytes, schwann cells, and endothelial cells were not found to react with the inos mrna-positive cells. cells positive for inos mrna were concentrated in regions immediately sur- rounding the ms plaque areas of extensive damage to white matter andadiminishing gradient of positives andevidenceof damage to astrocytes could be seen at increasing distances from the plaques. regions further removed ( mm) from plaques contained few if any inos mrna-positive cells and little evidence of the destruction of astrocytes. furthermore, nitration of tyrosine was evident in the vicinity of plaques implicating peroxynitrite in the pathogenesis of the lesions. while our reagents were unable to distinguish between monocyteymacrophages and glial cells, it is important to note that we observed cells positive for inos mrna either in the lumen of blood vessels or apparently adherent to the vascular endothelium in sections from ms brain. the apparent emer- gence of inos-positive cells from the blood vessel in the ms-plaque area indicates the likelihood that these are mono- cytes that have been activated in peripheral lymphoid tissues prior to infiltrating into the brain. in eae animal models, inhibition of the induction of inos hasbeen successfullyused for treatmentof clinical disease ( ). d indirectly suppresses severalbiologicalprocesses, includ- ing inos activation and tumor necrosis factor-a-induced apoptosis, by inhibiting the activation of phosphatidylcholine- specificphospholipasec,anenzyme involved in theregulation of the promoter nf-kb ( ). in our hands, plp-immunized swxj- did not develop eae while under treatment with mgofd (fig. ).clinical signsofeaeappeared hrafter discontinuing d . because the dosage of d was chosen more or less arbitrarily, it is possible that a higher dose or prolonged treatment may have a more lasting effect. alterna- tively, d -insensitive pathways leading to the formation of active inos may exist (e.g., ref. ). in the latter case, a scavenger of no, like c-ptio, would be expected to be more effective. indeed, c-ptio had significant effects on the development and severity of the clinical signs of eae in our experiments. the therapeutic action of c-ptio was improved by more frequent administration (fig. b) as expected based on the short biological half-life of c-ptio in the blood of experimen- tal animals. in fact, it has been reported that % of the c-ptio administered to mice is excreted within . hr ( ), raising the possibility that the therapeutic effects of c-ptio seen in this study might not entirely depend on its continued presence in vivo. the finding that no levels in the brains of plp-immunizedmice treatedwithc-ptioremainmuch lower than those in spinal cord evidently suggest that the clinical signsofeae, in thismodel,maybeassociatedwithhigh levels of no in brain rather than spinal cord (fig. ). even though c-ptiomayhaveaneffect on theotherbiological rolesofno in the nervous and circulatory systems ( , ), its strong therapeutic effect in eae was without notable side effects. we have found that treatment with uric acid, a known scavenger of peroxynitrite, can virtually block clinical disease in swxj- mice. the fact that mice remain healthy when treatedwithuricaciddespitehavingelevatednolevels intheir brains and spinal cords provides evidence for the assumption that no derivatives may be more toxic in eae than no itself. becauseuric acid is highly insoluble in aqueous solutions ( ), a significant proportion of the uric acid administered i.p. as a suspension in pbs accumulated in the peritoneum. it was therefore difficult for us to accurately determine the effective therapeutic dose. in the future, analysis of serum uric acid levels will be used to shed more light on this problem. since, in contrast to man, mice metabolize uric acid in an additional step to allantoin ( ), it is conceivable that this compound, although not known to be a free radical scavenger, may be the protective molecule rather than uric acid. however, based on its knownperoxynitrite binding activity,we speculate that uric acid is the active protective molecule in the mouse eae system. in this investigation we have shown that treatment with an inhibitor of inos activation and scavengers of no and per- fig. . effectof theadministrationof variousdosesofuric acidon the

eae. we are now investigating the mode of action of d , c-ptio, and uric acid in mice with chronic recurrent eae. if treatment is successful under these circumstances,onemayconsider theuseof these substances in the therapy of chronic degenerative cns diseases of humans such as ms. thefactors involvedintheformationofplaques inthebrains ofmspatientshavebeenhithertounknown.ourdata strongly suggest that activated macrophages are causing these lesions through the production of no and, subsequently, peroxyni- trite. inhibitors of these substancesprovide a strong therapeu- tic effect in eae and, because the inhibitors act at the postinductioneffector stageof thedisease, shouldbeuseful in blocking the development of cns lesions in ms regardless of its etiology. the properties of c-ptio are not as well known as those of the natural compound uric acid, initially isolated in the late th century ( ). in the case of c-ptio, toxicity studies must beperformedbefore further experimentation,whichmay lead to applications in humans. in the case of uric acid, further studies are necessary to clarify our hypothesis that there is a negative association between uric acid on the one hand and peroxynitriteand itspathogenic role inmsontheother.these studies may include a determination of whether abnormalities in the metabolism of uric acid may have some effect on the incidence or course of ms. for instance, a statistical survey of patients with gout for incidence of ms may indicate that hyperuricemia may preclude the development of ms and provide a basis for the extension of our experimental studies to the treatment of ms with uric acid. we thank inglis house (philadelphia) for assisting in the procure- ment of tissue samples, dr. mark curtis (department of neurology,

development of two instruments to capture ease-of-care outcomes in health-care providers who care for patients treated with pca delivery systems abstracts treatment among occupational injury cases. methods: an analysis of a state-based worker’s compensation claims data captured prescription reimbursement information of all injuries that occurred between january , and december , . payment information was followed over a -month period fol- lowing date of injury. a prescription sequence analysis was carried out to estimate treatment incidence rates of potential addiction due to narcotic analgesic use. results: of the , occupational injury cases, about % (n = ) received at least narcotic analgesic (therapeutic class h a). average length of therapy was days, with % of patients receiving nar- cotic analgesics for greater than days. the majority of nar- cotic prescriptions were for hydrocodone ( %). nine percent of patients received less than four different types of narcotic anal- gesics. from the prescription sequence analysis, we identified cases who received either methadone or clonidine, medications indicated for addiction treatment or detoxification. the inci- dence rate of receiving treatment for narcotic withdrawal or detoxification was per patients on narcotic analgesic therapy ( % ci: . , . ). among patients who received potential detoxification treatment, the median duration from ini- tiation of narcotic analgesic therapy to need for withdrawal or detoxification therapy was days. a cox proportional hazards model identified greater risk of suspected methadone use in oxycontin treated patients compared to other narcotic treated patients (p < . ). conclusions: to our knowledge, this is the first study that estimated the incidence rates of sus- pected addiction treatment due to narcotic analgesics used in the worker’s compensation population using sequential prescription analysis. the study has implications for developing strategies to manage narcotic analgesic prescribing practices and reduce the risk of addiction among injured workers who are narcotic anal- gesic users. pain pain—methods and concepts ppn development of an

department of anesthesiology patient controlled analgesia (pca) is a common method of post- surgical pain management. the extent to which this method is optimal in terms of overall convenience, ease of use, and effec- tiveness of managing pain from a patient’s perspective has not been determined. objectives: to develop a questionnaire to measure “ease-of-care” outcomes from the perspective of patients who use pca delivery systems for post-operative pain management. methods: we conducted qualitative interviews among a convenience sample of patients who had undergone hip or lower abdominal surgery and who received intravenous (iv) pca for their post-operative pain at thomas jefferson uni- versity medical center during june . a content analysis approach was used to identify domains of relevance and gener- ate an item pool. content validation of the draft “ease of care” questionnaire was performed by subjects who participated in the initial interviews. subjects were asked to rate the relevancy of each item on a scale of zero (not at all relevant) to four (highly relevant). each item was assessed for clarity and relevance, and revised as appropriate. cognitive debriefing interviews to evalu- ate patient experiences completing the instrument were conducted with a separate sample of patients from the same institution who completed the questionnaire approximately – hours post-surgery. results: the final patient ease-of-care ques- tionnaire consists of items and covers seven aspects associated with acute care pain management systems: control/self-efficacy, device function, mobility, quality of pain control, confidence, knowledge/understanding, and satisfaction. all items are scored on a -point likert scale. conclusion: we developed an instrument to capture “ease-of-care” outcomes among patients who use pca delivery systems for the management of their acute pain. the instrument is currently being used in clinical trials com- paring two pca delivery systems. psychometric properties of the instrument are currently being evaluated. ppn development of two instruments to capture ease-of-care outcomes in health-care providers who care for patients

capture “ease-of-care” outcomes among health-care providers to be used in upcoming studies of alternative pca delivery systems for the management of post-operative pain. the instruments are currently being used in clinical trials comparing two pca delivery systems. results will be used to examine the instruments’ psychometric properties. respiratory diseases/disorders respiratory

injuries of the lower limb, especially from penetrating gunshot wounds, and peripheral arterial diseases are on the increase and management of these and many other lower limb injuries involve increasing usage of vascular interventions like by-pass surgery, per-cutaneous transluminal angioplasty, arterial cannulation, arterial bypass graft or minimally invasive measures like percutaneous trans-arterial catheterization, among others. a thorough knowledge of infrapopliteal branching most especially their pathways and luminal diameters are important to surgeons in selecting appropriate surgical interventions or procedures. we report the case in which one of the terminal branches of the popliteal artery (ppa), the anterior tibial artery (ata) of good caliber size at origin became hypoplastic in the anterior leg region after giving off numerous muscular branches. continuing as an almost attenuated dorsalis pedis artery (adpa) in the dorsum of the foot, the latter was reinforced by an enlarged hypertrophied fibular artery. this case illustrates yet the importance of the fibular artery as the dominant of the infrapopliteal branching arteries, reinforcing or replacing the posterior tibial artery (pta) when it is weak or absent by a strong communicating branch or, reinforcing a weak ata and dorsalis pedis artery (dpa) by a strong perforating fibular artery as being reported. the pta however travelled a normal course yielding the medial and lateral plantar arteries posterior to the abductor hallucis muscle. this case demonstrates the importance of collateral communications and reinforcements from other infrapopliteal arteries, whenever one of its members or subsequent branches are absent or hypoplastic. a very sound knowledge of the various branching patterns of the ppa can be gained via pre-operatively vascular angiography, designed to guide the surgeon in the selection of appropriate surgical interventions, adding value to patients care in helping to reduce iatrogenic surgical vascular complications and reduction in total number of limb loss. key words: segmental hypoplastic anterior tibial artery; attenuated dorsalis pedis artery; hypertrophied fibular artery; infrapopliteal branching. introduction the popliteal artery is the continuation of the femoral artery beginning from the adductor hiatus. the artery des- cended laterally, crosses the popliteal fossa ending at the distal border of the popliteus where it divides to give the infrapopliteal terminal branches, the anterior tibial artery (ata), the posterior tibial/peroneal trunk (ptpt), the latter in turn gives rise to the peroneal artery about . cm distal to the ata. the latter runs in the fibrous canal between the tibialis posterior muscle and the flexor hallucis longus. embryologically, the sciatic artery is the embryonic vessels that supply the lower limbs. arising from the dorsal root of the umbilical artery, the sciatic runs through the thigh, knee and leg, lying between the tibia and popliteus. a perforating branch that communicates with the femoral artery arises from the distal border of popliteus. this branch called ramus communicans passes ventrally between fibular and the tibia to form the anterior tibial artery (ali & mohajir, ; brantley et al., ). persistent primitive arteria (ppa); segments, abnormal fusions, segmental hypoplasia or the absence of these arteries gave rise to anatomic variability. variations in the pattern of the ppa revolve around the “high division” of that trunk (keen, ) and the resulting differences in the arrangements of its terminal branches. the frequency of occurrence of “high division” of the popliteal artery are . % (poirier & charpy, ), about % (trotter, ), . % (adachi, ), while keen found times in * thomas jefferson medical college, thomas jefferson university, philadelphia, usa. limbs corresponding to %. trifurcation, is a popliteal arterial pattern where all the arteries may arise from the termination of the popliteal at exactly the same level or as long as the point of origin of the peroneal artery is mm or less from the main bifurcation (adachi). sometimes the ppa splits into trunks, an ata/peroneal (fibular) and posterior tibia trunk (ptt). infrapopliteal collaterals do exist between the branches of the major infrapopliteal arteries that do communicate to give vascular supply when one of these branches are weak or absent. such collaterals exist between the pa and the ata via the perforating fibular artery, between the peroneal and pta via a communicating branch. case report during routine academic anatomic dissection at thomas jefferson medical college of thomas jefferson university dissecting facilities, a very careful review of a pre-dissected lower limb by the undergraduate medical students, we observed that in the popliteal fossa, the infrapopliteal vessels were seen to be normal, yielding an initial trunks, a lateral one, which was the trunk to the ata, and a medial one, the posterior tibial and peroneal trunk (ptpt) which branched shortly to give the (pta) fig. . this image shows the anterior tibial artery travelling with the deep fibular nerve in the extensor compartment of the leg. the anterior tibial artery was of a good size proximally, but as it journeys inferiorly, it gives several muscular branches, becoming very hypoplastic. ata= anterior tibial artery, dfn= deep fibular nerve. hata= hypoplastic anterior tibial artery. fig. . this image shows the popliteal artery dividing to give it’s terminal branches, the anterior tibial, and common posterior tibial peroneal trunk which later divided to give fibular/peroneal artery and pos- terior tibia artery. at origin, all vessels including the

tibial artery. and the pa (fig. ). both the pta and pa travelled normally in the posterior leg, the pta travelled with the tibial nerve and distally bifurcated posterior to abductor halluces giving the lateral and medial plantar arteries. the ata however gave several robust muscular branches, became hypoplastic and on the dorsum of the foot. an hypertrophied perforating fibular artery was observed going through the intermuscular membrane to reach the dorsum of the foot (fig. ). we observed the popliteal artery (ppa) ending normally at about the distal border of the popliteus muscle, where it divided to give the ata and a ptpt, and at . cm distal to the ata, this trunk bifurcated yielding an pa laterally and the pta medially. none of the immediate branches of the popliteal artery, ata, pta and pa at origin was hypoplastic (fig. ). the ata was of a good caliber size at origin (about . mm in diameter), passes through the oval aperture in the proximal part of the interosseous membrane to reach the extensor compartment where we observed the ata supplying very prominent muscular branches to muscles in the anterior leg compartment (fig. ). ariyo, o. a segmental hypoplastic anterior tibial artery coexisting with an hypertrophied perforating fibular artery a case report and clinical implications. int. j. morphol., ( ): - , . following the giving off of the muscular branches, the ata became progressively smaller becoming more and more hypoplastic (fig. ), and by the time it crossed the ankle joint, it has become very attenuated and continued as an almost aplastic dorsalis pedis artery (adpa) (fig. ). on the dorsum of the foot, we observed an hypertrophied perforating fibular artery (hpfa) traversing the interosseous membrane to enter the extensor compartment. the hpfa divided into medial and lateral branches (fig. ). the medial branch was the replacement vessel for the dpa while the lateral branch was joined by a small twig from the adpa both skirting regions normally supplied by the arcuate arteries and its branches (fig. ). in the extensor compartment of the leg, we did not observe any muscular abnormalities, and no evidence of wasting or hypertrophy of muscles located on the dorsum of the foot and no evidence of hypertrophy, the deep fibular nerve (dfn) maintained the same relationship with the ata, travelling together anterior to the interosseus membrane, the pta branching pattern was observed normal, bifurcating posterior to the abductor hallucis to give the medial and lateral plantar arteries. neither of the plantar arteries was abnormal in size as observed visually even though the lateral plantar was observed bigger and was the main participant of the deep plantar arch, receiving a communicating branch from the hpfa. the ppa and its infra popliteal branching patterns in the r lower limb were normal. discussion reported variants of the popliteal artery are many. the artery may divide into its terminal branches proximal to popliteus in which case the (ata) sometimes descend anterior to the muscle. the size of the peroneal artery is said to be usually inversely related to the size of the ante- rior and posterior tibial arteries, either of which function the pa may assume (standring, ). variations in the pattern of the ppa revolve around the high division of that trunk. this high division was described as “at a level above the middle of the posterior surface of the popliteus muscle” (adachi). another variant of the popliteal artery pattern is “trifurcation”. in the latter all the terminal branches arise together at the inferior border of the popliteus muscle. keen reported observing a trifurcation of the ppa in of dissected yielding an incidence rate of . %, . % (poirier & charpy), . % (trotter), . % (adachi). kropman et al. ( ) reported that the most frequent variations in branching of the popliteal artery are a high origin of the ata, the trifurcation of the ppa and a hypoplastic or aplastic pta. some reported important characteristics of the ata are as follows: (a-f) (a). the greatest diameter of the ata was characteristics of the trifurcation pattern (dobbs et al., ). b) of the of the three calf arteries, the ata was the predominant vessel in a trifurcation and in subtypes with anterior tibioperoneal trunk (lippert & pabst, ; kim et al., ). c). an association has been found between ata and bony malformations of the lower limbs (hootnick et al., ). hootnick et al., also concluded that in limbs that contain the remnant of a missing structure, that injury occurred after the mesenchyme was instructed to form that structure such abnormalities are termed “post-specification” defects, these being in contrast to those described as “pre-specification” malformations, of which a duplicated artery is an example of the latter, where the injury affected the signal before the instruction of the mesenchyme to develop into a specific structure was completed. (d). the luminal diameter of the ata is the most important determination of the patency fig. . this image shows the hypoplastic anterior tibial artery crossing the ankle joint, and becoming an attenuated dorsalis pedis artery in the foot. an enlarged/hypertrophied perforating fibular artery is observed emanating from the interosseus membrane and serves as the replaced dorsalis pedis artery in the dorsum of the foot. hata= hypoplastic anterior tibial artery, adpa= attenuated dorsalis pedis artery, hpfa= perforating fibular artery, rdpa= reinforcing dorsalis pedis artery, edb= extensor digitorum brevis. ariyo, o. a segmental hypoplastic anterior tibial artery coexisting with an hypertrophied perforating fibular artery a case report and clinical implications. int. j. morphol., ( ): - , . rate in anterior femorotibial graft (karmody et al., ; kremen et al., ). e). the luminal diameters of the ata closely correlated with the percentage of the three- year patency rate for bypass (karmody et al.; kremen et al.) and the cumulative limsalvage (karmody et al.). f) popliteal arterial variants and the normative data for ata are important in vascular surgery below the knee following an angiographic study of the ata in patients with aortoiliac occlusive disease (szpinda, ). it has been reported that on variant patterns of the foot, the most common variant was that in which supply to the distal pta arose from the peroneal artery. atanasova et al. ( ) also reported the case of an hypoplastic ata, ending above the ankle joint and was replaced distally by a large branch from the pta the latter crossing the lowest portion of interosseous membrane. in the case being reported, an attenuated dpa, a distal vessel from an hypoplastic ata was reinforced by an hypertrophied perforating fibular artery the fibular artery represents a significant contributory vessel to the foot. a segmental hypoplastic. ata is a very rare infrapopliteal variant, and its occurrence no doubt supports the hypothesis by lohan et al. ( ), that trifurcation vessel imaging should be a prerequisite to fibular free flap harvesting. variation in dpa. palpation of the dpa is essential, particularly in suspected cases of arterial disorders. the dpa is also subjected to variations. tuncel et al. ( ) reported the case of a bilateral anomalous origin for dorsalis pedis arteries originating from the fibular arteries because of the hypoplastic nature of both anterior tibial arteries. the artery is recognized to play an important role in the microvascular surgery of the foot during replantation, reconstructions and repair due to its unique anatomical position and bountiful supply to the foot (vijayalakshmi et al., ). a good knowledge of the infrapopliteal variants and their branching patterns are critical in assisting vascular, orthopedic and plastic surgeons in making well informed decisions before embarking on any surgical interventions in the lower limb. pre-operative mr angiographic study of infrapopliteal vessels and its branches will assist in revealing the presence of any existing malformations that may have important bearing on the choice of appropriate surgical procedures. acknowledgements the author would like to thank the giver of this body for her generosity, even after death continues to give contributions to human knowledge. thanks to the medical students who made an initial partial dissection on the cadaver, the friendly and scholarly environment provided by the various authorities of the department of pathology, anatomy and cell biology. the tireless efforts of david and karen of the medical media unit in taking the photographs are appreciated. ariyo, o. coexistencia de una arteria tibial anterior hipoplásica segmentaria con una arteria fibular perforante hipertrofiada. reporte de caso e implicacias clínicas. int. j. morphol., ( ): - , . resumen: las lesiones vasculares de los miembros inferiores, especialmente las heridas penetrantes por arma de fuego y enfermedades arteriales periféricas, están en aumento. su manejo, así como el de otras lesiones en los miembros inferiores, implican un mayor uso de intervenciones vasculares como la cirugía de by-pass, angioplastía transluminal percutánea, canulación arterial, injerto de derivación arterial o medidas mínimamente invasivas como el cateterismo transarterial percutáneo, entre otros. el conoci- miento profundo de las ramificaciones infrapoplíteas, muy especialmente sus vías y diámetros luminales son importantes para los cirujanos en la selección de las intervenciones o procedimientos quirúrgicos apropiados. presentamos un caso en el cual, una de las ramas terminales de la arteria poplítea (app), la arteria tibial anterior (ata), de buen calibre en su origen se hizo hipoplásica en la región anterior de la pierna después de un desprendimiento de numerosas ramas musculares. continuó como una arteria dorsal del pie (adp) casi atenuada en el dorso del pie; esta última se vio reforzada por una amplia arteria fibular hipertrofiada. este caso ilustra la importancia de la arteria fibular como dominante de las ramificaciones de las arterias infrapoplíteas, un refuerzo o sustitución de la arteria tibial posterior (atp) cuando es débil o está ausente, por una fuerte rama comunicante, o bien refuerzo de una débil ata y adp por una fuerte arteria fibular perforante como en el caso reportado. la atp sin embargo tenía un trayecto con un curso normal generando las arterias plantares medial y lateral, posterior al músculo abductor del hállux. este caso demuestra la importancia de las comunicaciones colaterales y refuerzos de otras arterias infrapoplíteas, cada vez que uno de sus componentes o ramas posteriores están ausentes o hipoplásicas. un conocimiento detallado de los diferentes patrones de ramificación de la app puede ser adquirido a través de una angiografía vascular previo a la cirugía, diseñada para guiar al cirujano en la selección de las intervenciones quirúr gicas adecuadas, agrega valor a la atención de los pacientes, ayuda a disminuir las complicaciones vasculares quirúrgicas iatrogénicas y reduce el número total de pérdidas de miembros inferiores. palabras clave: arteria tibial anterior hipoplásica segmentaria;

"you may promise yourself everything-but health, without which there is no happiness. an attention to health then should take place of every other object." in times of illness the sick person should seek recourse to enlightened medicine. jefferson was inoculated against smallpox in by the philadelphia physician william shippen. when he dislocated the wrist of his right hand in september , he was visited twenty times by one of the surgical luminaries of paris, antoine louis, permanent secretary of the royal academy of surgery.

"an academic village instead of a large and common den of noise, filth and fetid air. it would afford the quiet retirement so friendly to study and lessen dangers of fire, infection and tumult." six years later, in april , he added, "this village form is preferable to a single great building for many reasons, particularly on account of fire, health, economy, peace and quiet." jefferson's plan compares strikingly with the pavilion hospitals of the paris academy in the s, not only by the same symmetrical placement of neo-classical buildings, but also because the french reformers had abandoned the huge hospital monolith for precisely the same motives enumerated by jefferson a generation later. the scientists had settled on pavilion architecture with its superior fenestration and h. bloch, 'thomas jefferson to . thoughts on medicine, child care and welfare', n. y. state j. med., (december , ), pp. - . for jefferson's activities as a vaccinator, cf. w. b. blanton, medicine in virginia in the eighteenth century, richmond, garrett & massie, , pp. - ; e. t. martin, thomas jefferson scientist, new york, h. schuman, , p. ; b. s. leavell, 'thomas jefferson and smallpox vaccination', trans. am. clin. and climatol. assoc., , : - . blanton, op. cit., note above, pp. ff.; h. gill, the apothecary in colonial virginia, williamsburg, colonial williamsburg foundation, , appendix i, 'revolutionary hospitals in williamsburg', pp. - . the portable thomas jefferson, ed. m. d. peterson, new york, viking, , pp. - ; jefferson to dr benjamin rush, ford, writings of tj, op. cit., note above, vol. , p. . r. a. halsey, how the president thomas jefferson and dr. benjamin waterhouse established vaccination as apublic health procedure, history of medicine series ... library of the new york academy of medicine, no. , new york, the author, . january , to littleton tazewell, quoted in d. guinness and j. t. sadler, mr. jefferson architect, new york, viking, , p. .

"it is in this part of medicine that i wish to see a reform, an abandonment of hypothesis for sober facts, the first degree of value set on clinical observation and the lowest of visionary theories," a medicine based on "observation and experiment". rigorously trained doctors would enhance the health of the citizenry and thereby increase the potential for the enjoyment of natural rights and the strength of the political system. one of the university's six professors would teach anatomy, surgery, history of the progress and theories of medicine, physiology, pathology, materia medica and pharmacy. the university of virginia provided the first full-time state-supported clinical faculty in a university medical school in the united states. the comprehensive medical and scientific curriculum planned by jefferson, the emphasis on preclinical training and clinical instruction under close supervision of the medical school faculty became the norm in on lavoisier's experiments on

practitioner and scholar robley dunglison to assume the clinical chair, a man responsible for training numerous doctors in the young republic. a second faculty member, john patton emmett, professor of natural history, gave medical instruction in chemistry, botany and comparative anatomy. dr thomas johnston became the first demonstrator in anatomy and surgery. jefferson believed fervently in clinical and anatomical studies as the basis of medical education. no expense was spared in this area of university instruction. before march , jefferson had designed an "anatomical theatre" to perform dissections. construction was underway before his death a year later and completed in . a letter to dunglison of november included the draft of a prosposal for a university dispensary. approved by the board of visitors on april , only three months before jefferson's death, the clinic would provide vital learning experience to physicians in training, including surgery (which, jefferson had written earlier, was the only branch of the medical art lacking in virginia ) "for the purpose of dispensing medical advice, vaccination, and aid in surgical cases of ordinary occurrence to applicants needing them". those who could afford it would pay a fifty-cents fee; the indigent would receive services free. not only would medical science be served through the educational function of the dispensary, but the sick poor would receive life-promoting attention. no doubt in jefferson's mind the dispensary represented an efficient form of assistance, satisfying the moral responsibility of society to provide health services to those in need. clinical medicine was joined to compassionate care. the poor patient would be treated through the latest advancements of medical science and with humane consideration. reason and the moral sense came to form a sympathetic alliance, a merging of "head and heart" which perhaps best characterizes the 'jeffersonian position on health-care. viewed in this light, his university of virginia was not merely the emblem of freedom and progress through enlightenment but also an instrument for the improvement of the human condition through better health, and with it greater happiness, independence and material prosperity. jefferson esteemed the paris architecture he studied in the s as the standard by which to measure great

a permeability transition pore - ptp in mitochondrial inner membrane. on the other hand apoptosis induces opening of a large non-selective channel (mito- chondrial apoptotic channel - mac) in the mitochondrial outer membrane. we used atomic force microscopy to study the structure and organization of native mitochondrial membranes isolated from necrotic and apoptotic cells. we com- plement our afm imaging with nanopatricle-based immnunoassays, where mi- tochondrial membranes are pretreated with nanoparticle-conjugated antibodies for recognition of specific proteins. we will present our data on morphological studies of these membranes and will discuss feasibility of this approach for visu- alization of mptp and mac channels in the native mitochondrial inner mem- branes (mim) and mitochondrial outer membranes (mom) using afm methods. -pos board b heterogeneity of cardiolipin regulation yi-fan lin, mei-jie jou. department of physiology and pharmacology, chang gung university, tao-yuan, taiwan. cardiolipin (cl), is a protective phospholipid located exclusively on the mito- chondrial inner membrane for stabilizing individual complex of mitochondrial respiratory chain for energy production, mitochondrial ca þ (mca þ) regula- tion and reactive oxygen spices formation. deficiency of cl has been associated with multiple mitochondrial dysfunctions upon pathological condition, diseases and aging. using fluorescence digital imaging microscopy this study investi- gated how cl is preciously regulated in rat brain astrocytes rba- . results demonstrate that at the resting stage, the distribution of cl is rather heteroge- neous within single cell. the perinulear mitochondria show lower cl than mi- tochondria from the peripheral area. heterogeneity of cl was observed even in single mitochondrion, which may affects mitochondrial fission and fusion mechanism. cl was found to be higher at the cross point area of mitochondrial network. thread-like mitochondria and granular-like mitochondria, however, contain similar level of cl. some of the thread-like mitochondria even contain lower cl than granular-like mitochondria. upon localized oxidative stress in- duced by nm laser irradiation, heterogeneous depletion of cl was observed among mitochondria populations within single cell. distribution of cl altered also mitochondrial dynamics that depletion of cl always occurred before fis- sion. intriguingly, although complete depletion of cl is irreversible upon high strength of laser irradiation, depleted cl recovered during lower strength of laser irradiation and occurred heterogeneously within mitochondria popula- tions. condensation of cl was observed upon various stresses including oxida- tive stress induced by nm laser irradiation, ionomycin-induced mca þ stress and arachidonic acid-induced lipid stress which crucially enhances pres- ervation of cl and its resistance to stress which may be of significance for mi- tochondrial protection and survival. unveiling pathophysiological regulation of cl thus may contribute significantly the prevention and treatment of cl asso- ciated pathological condition, diseases and aging.

gung university, tao-yuan, taiwan. mitochondrial dynamics including morphological fission and mitochondrial movement are essential to normal mitochondrial and cellular physiology. this study investigated how mtdna t g (narp)-induced inhibition of mito- chondrial complex v altered mitochondrial dynamics in association with a pro- tective mitochondrial phospholipid, cardiolipin (cl), as a potential therapeutic target. narp cybrids harboring % of mtdna t g genes and its parental osteosarcoma b cells were studied for comparison, and protection provided by melatonin, a potent mitochondrial protector, was explored. we demonstrate for the first time that narp mutation significantly enhances apoptotic death as a result of three distinct lethal mitochondrial apoptotic insults including oxida- tive, ca þ and lipidstress. in addition, narpsignificantly augmented patholog- ical depletion of cl. narp-augmented depletion of cl results in enhanced retardation of mitochondrial movement and fission and later swelling of mito- chondria during all insults. these results suggest thatcl is a common and crucial pathological target formitochondrial apoptoticinsults. furthermore, cl possibly plays a central role in regulating mitochondrial dynamics that are associated with narp-augmented mitochondrial pathologies. intriguingly, melatonin, by differ- entially preserving cl during various stresses (oxidation > ca þ > lipid), res- cuesdifferentially cl-altered mitochondrial dynamics and cell death (oxidation > ca þ > lipid). thus, melatonin, in addition to being a mitochondrial antioxidant to antagonize mitochondrial oxidative stress, a mitochondrial permeability tran- sition modulator to antagonize mitochondrial ca þ stress, may stabilize directly cl to prevent its oxidization and/or depletion and, therefore, it exerts great po- tential in rescuing cl-dependent mitochondrial dynamics-associated mitochon- drial pathologies for treatment of narp-induced pathologies and diseases. -pos board b shuttling of membrane-bound cytochrome b between mitochondria and er david weaver , veronica eisner , peter varnai , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis medical university, budapest, hungary. cytochrome b type b has long been described as a tail-anchored protein of the outer mitochondrial membrane (cb -mito). using a fusion protein consisting of photoactivatable gfp fused to the c-terminus membrane-targeting segment of cb -mito, we have found that while this construct concentrates in the mitochon- drial membrane, it is continuously exchanged between the membranes of the mitochondrion and the endoplasmic reticulum. this effect does not depend on the presence of mitofusin or , as it occurs in mfn-null mefs as well as in wild type cells. interestingly, a point mutation in the hydrophobic, membrane-targeting sequence of cb -mito that was recently reported to prevent its association with autophagosome membranes, also eliminates its exchange with the er. while lipids and viral proteins have been shown to traffic from er to mitochondria, this is, to our knowledge, the first demonstration of such a back-and-forth shuttling, representing both a new aspect of the er- mitochondrial interface and an mfn-independent pathway for the exchange of an outer mitochondrial membrane protein. -pos board b dichotomy between mitochondrial ca d uptake and martix [ca d] in micu deficient cells tunde golenar , gyorgy csordas , fabiana perocchi , vamsi k. mootha , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, harvard medical school and massachusetts general hospital, boston, ma, usa. mitochondrial calcium uptake is central to cell physiology, but the underlying molecular mechanism remains elusive. recently, micu was identified as a mi- tochondrial protein required for ca þ uptake but dispensible for mitochondrial respiration or membrane potential generation. to study the specific role of micu in mitochondrial ca þ uptake, we used wild type hela cells (ctrl), micu knockdown by distinct shrnas (kd) and micu rescued cells (res- cue). first, we monitored the cytoplasmic and mitochondrial matrix [ca þ] ([ca þ]c and [ca þ]m, respectively) during store-operated ca þ entry. specif- ically, cells were preincubated in a ca þ-free buffer containing thapsigargin (tg), to deplete the er ca þ store, and then ca þ was added back and the en- suing [ca þ]c (fura ) and [ca þ]m (mitochondria-targeted pericams) changes were measured. in both ctrl and kd a [ca þ]c increase occurred that was asso- ciated with a [ca þ]m rise only in ctrl. the rescue behaved similarly to the ctrl. also, when ca þ was added to permeabilized cells, no [ca þ]m increase ap- peared in the kd. these results confirm that the shortage of micu causes sup- pression of the [ca þ]m signal. surprisingly, when the ca þ entry was followed byuncoupler additiontoreleasethemitochondrial ca þ content, ahuge[ca þ]c increase appeared in kd, however, when the uncoupler was added prior to ca þ entry, no [ca þ]c increase occurred. thus, mitochondria in the kd also accumu- lated ca þ during ca þ entry. mitochondrial ca þ uptake evoked by ca þ ad- dition was also documented in permeabilized kd by measurement of ruthenium red sensitive ca uptake and cytoplasmic ca þ clearance (fura ). thus, ca þ is accumulated by micu deficient mitochondria but it fails to result an increase in[ca þ]m.weare currentlyinvestigating, whether suppression ofthe [ca þ]m rise in the kd is due to enhanced matrix ca þ-buffering. -pos board b micu serves as a ca d-controlled gatekeeper for the mitochondrial ca d uniporter györgy csordás , tünde golenár , erin l.

mitochondrial potential and, fur- thermore, reversed mitochondrial depolarization induced by colchicine. to fur- ther explore a role vdac-tubulin interaction in cell proliferation and survival, we studied the effect of erastin, the selective anti-tumour agent involved in the ras-raf-mek signalling pathway, on vdac blockage by tubulin. we found that erastin reverses tubulin blockage of vdac isolated from hepg cells, pro- moting the unblocked state of the channel. our findings suggest a novel func- tional link between serine/threonine kinase signalling pathways, mitochondrial respiration, and highly dynamic microtubule network which is characteristic of carcinogenesis and cell proliferation. -plat the isoform specific n terminus of vdac is dispensable for tbid induced cytochrome c release shamim naghdi , peter varnai , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, department of pathology anatomy and cell biology, philadelphia, pa, usa, semmelweis university, faculty of medicine, department of physiology, budapest, hungary. vdac proteins represent a main component of the outer mitochondrial mem- brane (omm). the vdac family is composed of isoforms with more than percent similarity. although their primary role was known to be in ion and me- tabolite transport between mitochnodria and cytosol, it has been discovered that vdacs are involved in apoptotic pathways. we have recently found that spe- cifically the vdac isoform is needed for tbid-induced cytochrome c release, due to its role in supporting bak insertion to the omm (roy et al. . embo rep. : - ). sequence analysis of the mammalian vdac isoforms shows a unique n terminal end in vdac , which is likely to be exposed to the cyto- plasm. to test the functional significance of this n terminus, the first amino acids were removed from vdac or were added to vdac . vdac -/- mef cells that are resistant to tbid, were rescued with these constructs and cyto- chrome c release was monitored in permeabilized cells by single cell imaging and immunoblotting. these studies revealed that cytochrome c release upon tbid application is effectively supported by both full length vdac and the vdac n-terminal deletion mutant. furthermore, vdac extended by the n terminus of vdac failed to restore cytochrome c release in vdac -/- mefs. thus the n terminus of vdac seems to be dispensible for tbid- induced omm permeabilization. currently, we are designing different muta- tions which target some addititional unique sequences in vdac to find the specific domain that is essential for tbid induced cytochrome c release. -plat patch-clamp analysis of mitochondrial ca d uniporter in different tissues francesca fieni, yuriy kirichok. ucsf, san francisco, ca, usa. the mitochondrial ca þ uptake has been recognized as a central player in cel- lular pathophysiology for decades. pathways of ca þ transport across the inner mitochondrial membrane (imm) were investigated indirectly with biochemical techniques and most recently by applying the patch clamp technique to mito- plasts isolated from mammalian systems. patch-clamp recording of the imm have proved to provide an unambiguous picture of mitochondrial ca þ uptake under strictly controlled conditions. in this study, we evaluated and compared the biophysical properties of mito- chondrial ca þ uptake in different mouse tissues. freshly isolated mitoplasts from mouse heart, skeletal muscle, liver, kidney, spleen and brown adipose tis- sue were patch clamped in the whole-mitoplast configuration. voltage step and ramp protocols covering the whole range of physiological potentials were ap- plied to elicit the inwardly rectifying ca þcurrent sensitive to rur known as mcu. the distribution of mcu current densities between tissues was as fol- lows: spleen > brown adipose tissue z skeletal muscle > kidney > liver >> heart. interestingly, mcu current density in heart was about times smaller than in skeletal muscle. our results support the view of a differential tissue activity of mcu, which can be explained by either a different distribution of mcu channel and/or by a different expression of its regulatory subunits confer- ing various modes of physiological regulation. further on, in order to investigate the putative direct contribution of uncou- pling protein isoform and (ucp / ) to the uniporter, we investigated mcu properties in wild type (wt) mouse tissues where these two proteins have been found to have a major role and compared its properties in the corre- spondent tissues of ucp and ucp ko mice. we found no significant differ- ences in calcium currents of any of the wt tissues studied compared to their ucp / ko counterparts. -plat sr-mitochondrial ultrastructure in the heart of normal and ethanol-fed rats gyorgy csordas , david mankus , tanvir shaikh , xing meng , jan hoek , carmen mannella , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, wadsworth center, albany, ny, usa. chronic alcoholism causes various forms of stress in the heart, and this is often accompanied by mitochondrial dysfunction. a putative source of mitochondrial dysfunction is sr-mitochondrial stress and the ensuing mitochondrial ca þ overload. to test this possibility, first we isolated mitochondria from chronic ethanol-fed ( months) and paired control rats, and documented ethanol- dependent sensitization to ca þ and ros-induced permeabilization. to evalu- ate the ultrastructural basis of the mitochondrial impairments, we performed transmission electron microscopy (tem) and electron tomography studies of left ventricular muscle. the overall ultrastructure of the myocytes became less organized in the ethanol-fed condition. also, a considerable fraction of the mitochondria lost the highly ordered structure of the cristae and showed an increase in the cross-sectional area. however, the size of the sr- mitochondrial associations and the gap-width at the interface was unchanged. evaluation of the sr-mitochondrial tethers by electron tomography indicates that they occur in clusters and display heterogeneity in length, as previously re- ported for er-mitochondrial tethers in normal rat liver (csordas et al, , j cell biol, : ). overall tether length distribution appears to be unaltered by alcohol ingestion. analyses of effects of alcohol ingestion on tether membrane-surface density and structural classes (linear, v, y and more com- plex shapes) is in progress, as is d analysis of ser and mitochondrial inner- and outer-membrane topologies.

efficacy of the educational, self-help book the easy way to stop smoking by allen carr in achieving smoking cessation in patients being screened or currently being treated for cancers of the head and neck. a prospective, randomized control trial was conducted involving patients being screened or undergoing treatment for head and neck cancer at the thomas jefferson university hospital department of otolaryngology. participants completed surveys assessing readiness to quit smoking, amount of tobacco usage, and amount of time actively smoking. the easy way to stop smoking was provided to half of the participants, while the other half received a recommendation to purchase the book. all patients received physician directed smoking cessation counseling. phone surveys were conducted at short and long-term follow-up intervals to determine if the patients had purchased and/or read the book and whether they were still smoking. of the patients recruited, were eligible for follow-up, and only completed the long-term follow-up survey. the remaining participants were lost to follow-up for various reasons. those who received the book for free were more likely to read at least some of the book, p = . , although reading the book did not appear to correlate with successful smoking cessation, p = . . only % of patients who received the book (n = ) quit, while % of patients (n = ) who were recommended the book quit smoking, although this difference was not significant, p = . . patients who indicated “readiness” or “actively trying” to quit (n = ) appeared more likely to be successful than those who would only “consider” quitting (n = ), but the differences were not significant, p = . . smoking cessation rates did not appear to be impacted by reading allen carr’s the easy way to stop smoking. cessation rates between groups who read and did not read the book were similar, and the small differences were not statistically significant. despite a majority of the cohort indicating at least a readiness to quit smoking, only a small portion of patients managed to achieve successful smoking cessation. this study seems to support the notion that there is no single method to promote cessation, and that patient motivation remains an important factor in achieving long-term smoking abstinence. introduction: smoking is the most common preventable risk factor in the development of head and neck cancers[ ]. patients who smoke can be up to times more likely to develop cancers of the head and neck than non-smokers[ ]. oral cancer patients who continue to smoke are also at increased risk for developing additional primary malignancies[ ]. smoking cessation can reduce the risk of oral cancer by % within the first five years. after ten years, the risk of developing oral cancer approaches the risk of non-smokers[ ]. as such, it is extremely important to promote smoking cessation counseling in all patients who smoke, particularly those who have already been diagnosed with a head and neck malignancy. even after diagnosis, successful smoking cessation can improve survival rates. there are a variety of programs and interventions aimed at smoking cessation, although maintaining smoking abstinence is always a challenge. printed education materials have been found to improve physician practices, but their efficacy is as of yet inconclusive for patient outcomes[ ]. in the thomas jefferson university hospital department of otolaryngology, we believe one method that may be effective in convincing patients to quit smoking is the best-selling self-help book the easy way to stop smoking, by allen carr. this book explores the reasons people smoke, aiming to change smoker’s feelings about their addictions and challenge misconceptions in order to promote cessation. this study aimed to evaluate the efficacy of the educational, self-help book the easy way to stop smoking by allen carr in achieving smoking cessation in patients being screened or currently being treated for cancers of the head and neck. additionally, this study aimed to determine if providing the book for free improved the likelihood patients would read the book over recommending the purchase of the book. methods: study participants over the age of were recruited during office visits to the thomas jefferson university hospital – department of otolaryngology. current smokers who either underwent screening or were actively being treated for cancers of the head and neck were eligible for recruitment in this study. consenting participants were randomized into two treatment groups: intervention group: received physician counseling on smoking cessation with a recommendation to purchase the book the easy way to stop smoking by allen carr. control group: received physician smoking cessation counseling in addition to a free copy of the book the easy way to stop smoking books were provided by research nurses to allow for adequate blinding of the study physicians. recruited patients completed an “intake questionnaire” to determine, among other things, amount of cigarettes smoked per day, obstacles to quitting, family support, and readiness to quit smoking (evaluated on the following likert scale): = “not planning to quit” = “would consider [quitting] if a reasonable solution was provided” = “ready to take action” = “actively trying to quit” after the initial intake survey, patients were followed-up via phone at short (two weeks to six months) and long term intervals (six months to one year). timing of follow-ups depended on ability to reach the patients via phone. discussion: the easy way to quit smoking does not appear to be an effective intervention to promote smoking cessation by itself. reading the book did not appear to be associated with an increased likelihood to quit smoking. interestingly, those patients who did not read the book at all had the highest percentage of smoking cessation ( . %), as well as the highest mean cigarette reduction ( . %), although neither of these values were statistically significant, p = . and p = . , respectively. additionally, those patients who read the entire book (compared to those who read some or none of the book) showed the lowest average cigarette reduction ( . %), p = . . a cancerous diagnosis correlated with a minor increase in the likelihood that patients would quit smoking, although it was not a significant difference, p = . . these findings are inconsistent with the literature, as cancer has been shown to be an effective motivator for smoking cessation[ , ]. anecdotally, several patients surveyed admitted their cancer diagnosis was the major reason for their smoking cessation, and not the easy way to stop smoking. providing the intervention (i.e. allen carr’s book) free-of-charge ensured patients were more likely to utilize the intervention. those who received the book free of charge from the tjuh department of otolaryngology were more likely to read the book ( . %) than those who were only recommended to purchase the book ( %), p = . . when suggesting other smoking cessation interventions, cost to the patient may be a factor affecting compliance. identifying patients who are ready or motivated to quit smoking may be useful in targeting smoking cessation interventions, as these patients may be more likely to successfully quit smoking. finding the motivation to quit seems to be a major obstacle in smoking cessation, and is supported in the literature[ ]; those who are motivated to quit smoking are more likely to be successful. many of the study participants enjoyed reading the book, although few managed to successfully quit smoking during the study. patients who initially reported readiness to quit or were actively trying to quit smoking were successful in higher percentages ( . % and . %, respectively) than those who would only consider quitting ( %), p = . . despite a lack of statistical significance, these trends are certainly interesting. a similar study illustrated that patients with low motivation or low readiness to quit were unlikely to benefit from self-help materials, such as a smoking cessation book[ ]. the small sample size and large participant attrition are limitations of this study. while some attrition was expected, we did not anticipate losing the number of patients we did ( %). conducting the follow-up surveys via phone also presented challenges, as many of the study participants were either undergoing or recovering from treatment for head and neck cancers. likely, the stress and hardships associated with a cancer diagnosis contributed to some of the participant loss. another limitation was the study’s reliance on self-reported data collected in surveys. patients have been known to underestimate their cigarette intake[ ], and it’s entirely possible some patients may have overestimated the amount of the book they read. conclusion: nearly every patient surveyed that read the book enjoyed the the easy way to stop smoking, finding it both helpful and informative, although only a small percentage of patients managed to translate the book’s message into practice and achieve smoking cessation. due to the small sample size, it is difficult to make any concrete conclusions about the efficacy of allen carr’s the easy way to stop smoking, although the small percentage of patients who did quit smoking suggests there is no single “magic-bullet” approach that can tackle the intense nature of nicotine addiction. identifying a patient’s motivation to quit may be a useful tool in tailoring future cessation strategies and treatment, but achieving long-term smoking cessation still remains a major challenge to both patients and otolaryngologists. any attempts at promoting smoking abstinence should likely involve a multi- faceted approach. f( , ) = . , p = . acknowledgements: tara difabio, amy wotlinksi, and kristin loeb for their help in recruiting study

l’un est né en amérique, l’autre en angleterre ; l’un est citadin, l’autre planteur ; l’un est joueur et extroverti, l’autre sérieux et introverti ; tous deux sont mariés, mais si l’épouse de franklin n’occupe pas une grande place dans sa vie, celle de jefferson, vouée à un destin tragique, fut passionnément aimée, etc. de façon plus pertinente au regard du propos général, l’ouvrage met finalement l’accent sur l’anglophilie de franklin, qui évolua de telle façon qu’il se rangea finalement, en , du côté des insurgés, à la francophilie de jefferson, qui, lorsqu’il fut président, le fit pencher en faveur d’une neutralité raisonnée. de même — aux deux chapitres suivants qui traitent tour à tour de franklin puis de jefferson — l’auteur remarque que les missions des deux ministres intervinrent dans des contextes bien différents, puisque franklin dut se rendre en france pour demander une aide militaire à la cour de versailles et négocier un traité d’amitié en temps de guerre, alors que jefferson eut à confirmer et développer l’alliance française en temps de paix. toutefois, franklin réussit dans sa mission d’une façon plus éclatante que jefferson, puisqu’il obtint, grâce à ses négociations mais aussi parce que la france voyait là un moyen de contrer sa rivale, la signature des deux traités franco-américains de février , à savoir d’une part le traité d’amitié et de commerce et, de l’autre, le traité d’alliance militaire qui en permit l’envoi de troupes françaises sur le territoire américain et assura ainsi la victoire aux colonies rebelles. jefferson, lui, dut œuvrer dans un contexte de crise financière, la france affrontant alors une angleterre en pleine croissance économique, et faire face à la mauvaise volonté des français qui en signèrent un traité commercial, dit traité d’eden, avec l’angleterre. si les succès diplomatiques de jefferson furent limités, ses efforts vinrent consolider les acquis de franklin, dans la mesure où ils favorisèrent les transferts culturels entre france et etats-unis. c’est ce qui ressort des trois chapitres suivants où sont décrits les réseaux de connaissances — officiels et privés — de franklin et de jefferson. n. fouché insiste sur la continuité entre les deux ministres sur le plan social et sur leur complémentarité, même si jefferson ne bénéficia pas du même accueil à la cour que son prédécesseur. jefferson, comme franklin, entretint des liens amicaux étroits avec les philosophes et plus généralement les membres de l’élite française, confirmant ainsi l’amitié franco-américaine amorcée d’une façon tout à fait remarquable par son prédécesseur. À l’initiative des deux hommes, de nombreux échanges culturels et intellectuels eurent lieu, qui permirent à la france et aux États-unis de mieux se connaître et comprendre. À l’instar de franklin, dont les expériences sur l’électricité lui valurent d’être félicité par louis xv et admis à l’académie des sciences de paris, jefferson s’intéressait à la science — il proposa lavoisier comme membre de l’american philosophical society de philadelphie. il se passionnait tout particulièrement pour l’horticulture, importa des plants américains et chercha à faire partager son goût pour le vin français. c’est par l’intermédiaire de franklin que le duc de la rochefoucauld d’enville traduisit en français les constitutions de colonies américaines. de son côté, jefferson fit paraître en france ses notes on the state of virginia et collabora à la nicole fouché. benjamin franklin et thomas jefferson : aux sources de l’amiti... transatlantica, | rédaction de la déclaration des droits de l’homme et du citoyen. curieux, alerte, plus jeune que franklin lors de son séjour en france, jefferson est défini par n. fouché comme un moderne, issu de l’encyclopédisme des lumières, qui non seulement transmit à ses compatriotes une certaine image de la france — à travers l’architecture par exemple qu’il chercha à reproduire en virginie — mais aussi proposa aux français une incarnation de la spécificité américaine. jefferson toutefois ne vit pas tout de la france ; et en particulier ne vit rien de la misère du peuple. il ne semble pas avoir été conscient des fractures de la société française qui furent à l’origine des événements de , date à laquelle il est rappelé aux États-unis. les relations franco-américaines furent ensuite ternies par la venue du ministre plénipotentiaire français, genêt, qui en déclencha une vague de francophobie chez les partisans de washington, par le traité de jay en , qui remit en cause les traités de , et surtout par l’affaire xyz et la quasi- guerre avec la france en . président à partir de , jefferson acheta la louisiane à bonaparte tout en adoptant une position de neutralité vis-à-vis de la france. en somme, voilà un petit livre clair, de lecture facile et agréable, plus descriptif qu’argumentatif, qui intéressera tous ceux qui souhaitent faire le point sur le rôle des deux ministres en france, ou qui cherchent à en savoir plus sur le contexte des lumières et sur la place de franklin et de jefferson dans les cercles français de sociabilité entre et . toutefois, outre la tendance à la schématisation notée plus haut, soulignons le flou de certains passages, qui contraste avec le parti pris pédagogique du chapitre d’introduction. ainsi un lecteur non averti regrettera probablement l’absence de détails sur le contenu du traité de paris de . de même, la présentation de la venue de genêt est incomplète puisque l’accent est mis sur la francophobie déclenchée par les actions du ministre, sans que soit souligné le fait que cette francophobie ne s’étendait pas aux membres des sociétés démocratiques- républicaines, qui continuèrent à soutenir genêt même après son renvoi. index thèmes : recensions auteur nathalie caron université paris — nanterre nicole fouché. benjamin franklin et thomas jefferson : aux sources de l’amiti... transatlantica, | nicole fouché. benjamin franklin et thomas jefferson : aux sources de l’amitié franco-américaine - . received / / review began / / review ended / / published / / © copyright zhang et al. this is an open access article distributed under the terms of the creative commons attribution license cc-by . ., which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. finding the ‘qr’ to patient safety: applying gamification to incorporate patient safety priorities through a simulated ‘escape room’ experience xiao chi zhang , gretchen diemer , hyunjoo lee , rebecca jaffe , dimitrios papanagnou . emergency medicine, thomas jefferson university, philadelphia, usa . medicine, sidney kimmel medical college at thomas jefferson university, philadelphia, usa . department of emergency medicine, stony brook university hospital, stony brook, usa . hospital medicine, thomas jefferson university, philadelphia, usa  corresponding author: xiao chi zhang, xzhang @gmail.com disclosures can be found in additional information at the end of the article abstract medical errors are the eighth leading cause of mortality in the united states and contribute to over one million preventable injuries. in an effort to prevent medical errors, reporting systems serve as invaluable tools to detect patient safety events and quality problems longitudinally. historically, trainees (i.e., students and residents) rarely submit incident reports for encountered patient safety threats. the authors propose an immersive learning experience utilizing gamification theory and leveraging the increasingly popular ‘escape room’ to help resident trainees identify reportable patient safety priorities. all incoming intern physicians at the thomas jefferson university (jefferson) were enrolled in the patient safety escape room study as part of their residency orientation (june ). the residents were randomly divided into teams. each team was immersed in a simulated escape room, tasked with identifying a predetermined set of serious patient safety hazards, and successfully manually entering them into the jefferson event reporting system within the time allotted to successfully ‘win the game’ by ‘escaping the room’. quick response (qr) codes were planted throughout the activity to provide in-game instructions; clues to solve the puzzle; and key information about patient safety priorities at jefferson. all participants underwent a formal debriefing using the feedback capture grid method and completed a voluntary post-study survey, adapted from brookfield’s critical incident questionnaire (ciq). the study was irb exempt. thematic analysis of the post-activity ciq survey ( n = ) revealed that interns were engaged during the immersive learning experience (n = ) and were specifically engaged by having to independently identify patient safety threats (n = ). participants identified team role assignment (n = ) and effective communication (n = ) as the two most helpful actions needed to successfully complete the activity. participants were overall surprised by the success of the education innovation (n = ) and reported that it changed how they viewed patient safety threats. areas for improvement include clearer game instructions and using a more streamlined event reporting process. the escape room patient-safety activity allowed interns to actively engage in an innovative orientation activity that highlighted the importance of patient safety hazards, as well as providing them with the opportunity to document event reports in real-time. next steps will include longitudinally tracking the quantity of error reports entered by this cohort to determine open access technical report doi: . /cureus. how to cite this article zhang x, diemer g, lee h, et al.

) provide incentives to avoid potential penalties and public exposure; and ) ultimately improve patient safety [ ]. voluntary reporting systems, in contrast, are based on a passive form of surveillance, requiring personnel directly involved in a near-miss event to provide essential information and details [ ]. the latter system has the benefit of capturing true events or near misses that would assist in investigating and learning more about the circumstances surrounding the event [ ]. despite the confidentiality that comes with voluntary reporting, there are numerous limitations and barriers to effective, voluntary event reporting. common physician barriers for submitting incident reports include: ) lack of incident follow-up; ) long forms; ) perceived ‘trivial’ nature of the incident; ) lack of time; and ) unclear responsibility for making the report [ ]. furthermore, increased public pressure on preventable errors, coupled with the threat of legal action and additional psychological sequelae (i.e. guilt, anger, inadequacy, and depression) associated with these errors, can perpetuate a culture of blame and avoidance, and deter helpful voluntary incidental reporting [ - ]. while both reporting systems are integral for detection and improvement of existing infrastructure weaknesses, efforts are required to encourage the use of voluntary reporting system. clinician educators are tasked with teaching physicians-in-training medical and patient safety practices. teaching patient safety and error reporting to the graduate medical education (gme) audiences, however, is challenging. only a minority of event reports are contributed by resident physicians and fellows at thomas jefferson university (jefferson). in the setting of the aforementioned barriers to reporting, the authors also recognize that a new, unfamiliar system would potentially further deter new interns from reporting events. in effort to augment active learning and engagement with teaching voluntary event reporting, the authors developed an interactive, immersive learning experience incorporating gamification and leveraging the increasingly popular ‘escape room’ design to incoming jefferson intern and resident physicians to better identify potential patient safety priorities and zhang et al. cureus ( ): e . doi . /cureus. of practice logging these events into the jefferson event reporting system. ‘escape rooms’ have risen in popularity in creating a high-fidelity, foreign environment that rewards players for working together, solving clues, and completing successions of mind-bending tasks in order to ‘escape the room’ in a limited amount of time. notably, the immersive and adaptive nature of the escape room has enabled this team-building activity to be incorporated as an innovative educational tool for a multitude of medical specialties [ - ]. we propose that exposing incoming interns and residents to various team-based activities on critical patient safety priorities, as well as providing them with the opportunity for guided reflection during a facilitated debriefing, will allow them to ) identify local patient safety priorities; ) physically enter an event report using the jefferson event reporting system; and ) practice using teamwork skills to address patient safety threats. technical report study setting four standard simulation rooms at the rector clinical skills and simulation center at thomas jefferson university in philadelphia, pennsylvania (pa) were secured to create four separate escape rooms that were operated concurrently: two of these rooms simulated a hospital inpatient room, and the other two rooms simulated a patient room in the emergency department (ed). the activity took place in june , during new intern and resident orientation. study participant selection all participants were interns (i.e., post-graduate year one, pgy- , residents) beginning their training at thomas jefferson university hospitals. there were no exclusion criteria. all participants consented to participate in the activity. all incoming pgy- residents were asked to attend this activity as part of their orientation curriculum prior to starting their respective residency programs. materials required participants were not asked to bring any additional tools or materials to the escape room. specific equipment required for the escape rooms has been listed in table . zhang et al. cureus ( ): e . doi . /cureus. of patient safety escape room materials hospital bed mannequin computer (with internet connection to enter error report) ventilator sequential compression devices isolation cart with gowns opened lumbar puncture kit (with sharps removed for safety) identification bracelet falls risk bracelet allergy bands adult diaper yellow falls socks urinal restraints incentive spirometer quick response (qr) codes door sign paper chart clipboard with blank list for recording hazards and clues (appendix: hazard list) table : equipment and materials required for the patient safety escape room simulation cases personnel requirements in order to coordinate, facilitate, and set-up the rooms for each session, faculty members were recruited to supervise the events. there were four simulation facilitators, four simulation observers, two traffic controllers, and two debriefing facilitators. simulation facilitators were present in each of the rooms to provide any necessary hints, suggestions, or technical support to effectively guide the learners through the cases. observers were able to remotely view all of the student activity in a control room via video streaming through an encrypted, institution wireless network. traffic controllers helped organize and coordinate learners moving from room to room. the debriefing facilitators were tasked with debriefing teamwork skills used during the activity, as well as discussing patient safety hazards noted in the rooms. zhang et al. cureus ( ): e . doi . /cureus. of group structure all incoming interns were randomly divided into teams, each comprising seven to eight residents. teams were tasked to work together to identify a predetermined series of patient safety threats that were planted in each simulated escape room, and successfully enter these events into the jefferson event reporting system within the allotted time of minutes in order to successfully ‘escape the room’ and win the game. simulation sessions ran throughout the afternoon. groups were staggered, and interns were assigned a specific time to arrive at the simulation center. prior to arrival, they received a - minute didactic session on the jefferson event reporting system, which was led by the principal investigators (rj). participants received a brief primer on the concept of the escape room activity. they were then led to their respective escape rooms. the day was broken down into four -minute blocks (blocks - ) and took place from pm to pm (figure ). figure : participant flow for the escape room challenge etr: escape the room detailed activity description four simulation rooms were set up for the escape room activity, allowing four teams (up to players) to be assessed concurrently. half of the simulation rooms were designated as case (internal medicine case), and the other half were designated as case (emergency medicine case). cases and represented two distinct simulated clinical environments with a unique set of respective challenges and patient safety hazards (figures - ). each case was developed and revised by a multi-disciplinary team composed of senior faculty clinicians of different medical specialties in order to ) mitigate cognitive load;

appreciate learning preferences; and identify potential ideas for improvement during future iterations of the activity. responses from the questionnaire were evaluated for thematic codes through open-axial qualitative data analysis (xcz, dp). results one-hundred thirty total interns participated in the activity. all teams were able to successfully escape the room within the -minute time limit. thematic analysis of the post- activity ciq survey (n = , with a . % survey response rate) revealed that the learners were highly engaged by the format of the learning experience (n = ) and the opportunity to identify safety threats (n = ). furthermore, participants found that role assignment (n = ) and zhang et al. cureus ( ): e . doi . /cureus. of https://assets.cureus.com/uploads/figure/file/ /lightbox_ f fe e a d d b -figure- _feedback-capture-grid.png communication (n = ) were the two most helpful actions needed to succeed in the activity. participants were surprised by the overall success of the educational innovation (n = ) and reported that it changed the way they perceived patient safety threats, especially identifying easily-missed errors and the large heterogeneity that exists with regards to safety threats (n = ). areas for improvement focused primarily on logistical details, where the learners identified the documentation process (n = ) and the task completion ( n = ) of the jefferson event reporting interface as the most cumbersome, distancing and confusing elements of the activity. table illustrates a detailed thematic analysis of the ciq questionnaire. ciq indices number of themes identified thematic codes generated (with frequencies, n) most engaged immersion in an active learning experience ( );

and co-evolution with mcu. micu has been demonstrated to be a ca þ -sensing protein, which both sets a threshold for low ca þ concentration while it assures cooperative activation during high ca þ rises. mitochondrial ca þ uptake shows tissue specific differences and interestingly, mrna level for micus and mcus also displays tissue specificity. we set out to investigate if the stoichiometry between micu and mcu could account for the previously described differences between heart and liver in mitochondrial ca þ uptake. immunoblotting showed higher expression for all micu , micu and mcu in mouse liver versus heart mitochondria, and a . fold higher micu to mcu ratio in liver. in fluorometric measurements of mitochondrial ca þ uptake, heart mitochondria displayed a decreased threshold and lesser cooperativity compared to liver mitochondria. additionally, nad(p)h elevation was detect- able after exposure to moderate [ca þ ] elevations only in heart mitochondria. overexpression of micu in the heart using aav -micu tail-vein injection significantly increased the micu protein level without any changes of micu or mcu. this increased the micu to mcu ratio in the heart and led to increased thresholding and cooperativity, reproducing the liver-like mito- chondrialca þ uptakephenotype.viceversamicu downregulationintheliver has been shown to lower the threshold and cooperativity of mitochondrial ca þ uptake in hepatocytes. thus, heart and liver mitochondria show different levels of ca þ threshold and cooperative activation of ca þ uptake, which seem to result from differential quantitative relationship between micu and mcu. -pos board b er calcium release is tuned by mitochondrial redox nanodomains david m. booth , balázs enyedi , miklós geiszt , péter várnai ,

controlled increases of h o emerge as an intracellular signal. we hypothesized that ros and ca þ interact locally, in the restricted vol- ume of the er-mitochondrial interface. these physically tethered structures host enrichments of ion transport proteins such as the ip receptor, which support elevated nanodomains of ca þ during signalling events and are sensitive to h o . we used the genetically encoded h o sensor hyper incorporated into an inducible linker system to probe the redox environment at the er- mitochondrial interface in hepg cells. we found a moderately elevated h o nanodomain which developes into a h o transient following ip receptor- mediated er ca þ release and mitochondrial ca þ uptake. pharmacological in- hibition showed that the transient was dependent upon er ca þ, mitochondrial membrane potential and functional electron transport chain. hyper measure- ments of the mitochondrial intermembrane space revealed significantly elevated h o within this volume. using electron microscopy we found that hepg mito- chondria possess a cohort of dilated cristae, which disappeared following ip - linked ca þ release. paxilline that inhibits mitochondrial bkca channels blocked the cristae reshaping and also abolished the h o transient at the inter- face. furthermore, paxilline caused suppression of the ip -linked calcium signal, whereas interface targeted killer red, a photoactivated h o source, induced sensitization to the ip -linked agonist. we conclude that the intermembrane/ cristae volume of mitochondria represents an oxidized pool fed by the electron transport chain. ca þ -uptake stimulates expansion of the mitochondrial matrix via kþ and concomitant water uptake, squeezing the oxidized volume of the cristae to the interface. here, a transient h o nanodomain sensitizes ip recep- tors to further stimulation. we demonstrate a physiological setting where ca þ release may autoregulate using mitochondrial h o released from the cristae. -pos board b reactive oxygen species (ros) suppress mitochondrial motility valentina debattisti, masao saotome, sudipto das, gyorgy hajnoczky. mitocare center, thomas jefferson university, philadelphia, pa, usa. mitochondrial distribution and transport play pivotal roles for many cellular functions, including cell differentiation, cell division to ensure proper inheri- tance, apoptosis, atp supply at the local sites of demand, ca þ buffering for intracellular ca þ homeostasis. we previously showed that mitochondrial motility (mito-motility) is regulated by the cytosolic ca þ concentration ([ca þ]c), providing the basis for a homeostatic circuit in which the organelles decrease their movements along microtubules to locally buffer high [ca þ ]c and contribute to atp supply. mito- chondria are also a major site for production and scavenging of ros that serve as both a messenger and regulator of calcium signaling and are particularly rele- vant for the control of mitochondrial function. here we tested the hypothesis that ros target mito-motility to control mitochondrial function. h c myoblast cells were transfected with a mitochondrial matrix targeted yfp and then loaded with fura , to monitor the mito-motility simultaneously with [ca þ ]c. h o ( mm) caused a decrease in mito-motility ( %) and an elevation in [ca þ ]c (from to nm) at the same time. when the cells were incu- bated in a ca þ -free medium and were pretreated with thapsigargin to prevent ca þ entry and intracellular ca þ mobilization, respectively, h o continued to inhibit the mito-motility dose-dependently without any changes in [ca þ]c. these results indicate that h o can cause suppression of mito-motility through a ca þ independent mechanism we are currently analyzing.

involved in mitochondrial motility and inheritance, and particularly its calcium regulation, but the roles of the two isoforms have not been established. genetic deletion of miro in mouse is lethal at birth (nguyen et al., ) and fibroblasts (mefs) derived from miro ko em- bryos show abnormal mitochondrial distribution, but the calcium-dependent in- hibition of motility is unaffected and the respiratory and calcium buffering capacities are normal. neuron-specific knockout of miro leads to progressive deficits of upper motor neuron function, however mitochondria in processes of cortical neurons from miro ko and wild-type embryos showed comparable calcium-sensitive motility inhibition. while no significant increase in miro pro- tein was observed in miro ko mefs, these data raise two possibilities: miro and are interchangeable with regard to calcium regulation of mitochondrial motility or miro is the key player in this regard. to finally resolve this question, we are in the process of generating miro ko and miro / ko cell lines. -pos board b mitochondrial fusion dynamics in the heart veronica eisner , ryan cupo , erhe gao , györgy csordás , lan cheng , jessica ibetti ,

and permanent reorganization of mitochondria by fusion and fission. to directly evaluate mitochondrial fusion dynamics in cardiomyocytes (cm), mitochondrial matrix-targeted photoactivatable gfp and dsred were intro- duced either in vitro or in vivo by adenovirus and were followed by confocal microscopy. four conditions were analyzed: to h cultured neonatal and in vitro transduced adult cm, and cm from in vivo infected rat hearts. in the latter case, cm were isolated - days after infection and were imaged promptly or - h post harvesting. neonatal cm mitochondria form a highly connected network, whereas both in vitro and in vivo transformed cultured cm displayed only some connectivity. impressively, in vivo transduced adult cm that were imaged promptly after harvesting, unveiled a significantly higher con- nectivity among mitochondria than the - h cultured adult cm. furthermore, fusion events (f.e./ square micrometers/min) were almost absent in cultured in vitro transduced cm, meanwhile in vivo transduced and cultured cm showed . . f.e./min, whereas isolated, freshly-imaged cm displayed . . f.e./min. imaging in perfused whole heart ex vivo, showed consider- able mitochondrial continuity and fusion activity in ventricular cm. to study more directly the role of cm’s contractile activity in mitochondrial fusion, cm were incubated with verapamil ( mm), that blocked spontaneous contrac- tion and partially suppressed the fusion activity of mitochondria. also, mito- chondrial fusion activity appeared to be higher after spontaneous contraction or short term field stimulation in isolated freshly-imaged cm. thus, mitochon- dria are dynamic in both neonatal and adult cm, but under culture conditions, adult cm lose mitochondrial fusion activity. this might be at least in part, because cardiomyocyte contractile activity is altered in culture and contractions likely provide some factors to support mitochondrial fusion activity. -pos board b mechanistic

american general elderly population has a pronounced hypothyroidism and relies on thyroid hormone supplements daily. the prevalence of hypothyroidism in our patients with pancreatic cancer was much higher, . %. a retrospective analysis was performed on patients who underwent pancreaticoduodenectomy (whipple procedure) or distal pancreatectomy and splenectomy (dps) at thomas jefferson university hospital, philadelphia, from to . the diagnosis of hypothyroidism was correlated with clinicopathologic parameters including tumor stage, grade, and survival. to further understand how thyroid hormone affects pancreatic cancer behavior, functional studies including wound-induced cell migration, proliferation, and invasion were performed on pancreatic cancer cell lines, miapaca- and aspc- . we found that hypothyroid patients taking exogenous thyroid hormone were more than three times likely to have perineural invasion, and about twice as likely to have higher t stage, nodal spread, and overall poorer prognostic stage (𝑃 < . ). pancreatic cancer cell line studies demonstrated that exogenous thyroid hormone treatment increased cell proliferation, migration, and invasion (𝑃 < . ). we conclude that exogenous thyroid hormone may contribute to the progression of pancreatic cancer. . introduction invasive pancreatic cancer is the fourth leading cause of can- cer death in the united states. most patients with pancreatic cancer have a dismal prognosis and a median survival rate of less than months [ , ]. at the time of diagnosis, the disease is often discovered to be in its late stages, as more than % of patients have tumors that have metastasized [ ]. currently, surgery remains one of the few options to decrease pancreatic cancer mortality. despite many advances in cancer biology over the past years, pancreatic cancer remains an elusive disease process that requires further studies to understand its molecular biology and investigate possible therapeutic targets. thyroid hormones (t and t ) are steroid hormones that regulate body growth, brain maturation, and metabolism. although the major product of the thyroid is t , most of it is converted to more biologically active t that binds to nuclear thyroid receptors and modulates the expression of proteins traditionally known to increase basal metabolic rate and enhance growth [ ]. disorders of the thyroid that result in either a deficiency or excess of thyroid hormones are extremely common and can have various effects on the human body. according to the nhanes national – survey, the prevalence of hypothyroidism in the general us population was . % [ ]. of note, the prevalence of thyroid disorders increases with age (up to . % for years and hindawi publishing corporation journal of yroid research volume , article id , pages http://dx.doi.org/ . / / http://dx.doi.org/ . / / journal of thyroid research older) and is consistent with females having higher rates of hypothyroidism than men [ – ]. due to the established effect of thyroid hormone on growth and development, many have hypothesized a con- nection between thyroid hormone and cancer. one of the first reports linking these two comes from a article that examines the relationship between supplemental thyroid hormone intake and breast cancer. in a study with , female patients, it was calculated that the rate of breast cancer in patients taking thyroid supplements for hypothyroidism was . % versus . % in a control group [ ]. since then, many studies have sparked a debate about a relationship between hypothyroidism and malignancy. a search of the literature reveals that hypothyroidism may be a risk factor for respiratory, colon, breast, and liver cancer [ – ]. cell line experiments in breast and prostate cancer corroborate these findings by demonstrating that treatment with t enhances cellular proliferation [ , ]. in this study, a retrospective analysis was performed on patients who underwent pancreaticoduodenectomy (whip- ple procedure) or distal pancreatectomy and splenectomy (dps) at thomas jefferson university hospital, philadel- phia, from to . the diagnosis of hypothyroidism was correlated with clinicopathologic parameters including tumor stage, grade, and survival. to further understand how thyroid hormone affects pancreatic cancer behavior, functional studies including

study, a database search was conducted for patients who underwent pancreati- coduodenectomy (whipple procedure) or distal pancreatec- tomy and splenectomy (dps) at thomas jefferson university hospital, philadelphia, pa, from to . the eligibility criteria consisted of patients with a diagnosis of invasive pancreatic cancer confirmed by biopsy. exclusion criteria consisted of patients with a history of noninvasive, benign pancreatic pathology or incomplete medical history. data collection included patient sex, age, body mass index (bmi), medical history, medications, surgical information, survival, tumor staging, and differentiation by hypothyroid status. the tnm staging system as outlined by the american joint committee on cancer (ajcc) was used to define pancreatic lesions. patients were defined to be hypothyroid if they had a positive medical hypothyroidism and were taking synthetic or desiccated thyroid hormone. the institutional review board of thomas jefferson university hospital, philadelphia, pa, approved this study. miapaca- (atcc crl- ) and aspc- (atcc crl- ) were purchased from atcc. mtt cell growth, migra- tion, and transwell invasion assays were performed as previ- ously described [ ]. . . statistical analyses. descriptive statistics were calculated on patient clinicopathological features. differences in gender, smoking status, venous-lymphatic invasion, perineural inva- sion, t stage, n stage, prognostic stage, and differentiation by hypothyroid status were determined by chi-square test. differences in age and bmi were determined by unpaired stu- dent’s 𝑡-test. survival analysis was performed using kaplan- meier curves and mantel-cox log rank test, where survival was defined as time between date of surgery and date of death or of last follow-up. all functional experiments were performed to times. functional studies were analyzed for statistical significance by student’s 𝑡-test analysis, or two- way anova. data are presented as mean

sets a threshold for low ca þ concentration while it assures cooperative activation during high ca þ rises. mitochondrial ca þ uptake shows tissue specific differences and interestingly, mrna level for micus and mcus also displays tissue specificity. we set out to investigate if the stoichiometry between micu and mcu could account for the previously described differences between heart and liver in mitochondrial ca þ uptake. immunoblotting showed higher expression for all micu , micu and mcu in mouse liver versus heart mitochondria, and a . fold higher micu to mcu ratio in liver. in fluorometric measurements of mitochondrial ca þ uptake, heart mitochondria displayed a decreased threshold and lesser cooperativity compared to liver mitochondria. additionally, nad(p)h elevation was detect- able after exposure to moderate [ca þ ] elevations only in heart mitochondria. overexpression of micu in the heart using aav -micu tail-vein injection significantly increased the micu protein level without any changes of micu or mcu. this increased the micu to mcu ratio in the heart and led to increased thresholding and cooperativity, reproducing the liver-like mito- chondrialca þ uptakephenotype.viceversamicu downregulationintheliver has been shown to lower the threshold and cooperativity of mitochondrial ca þ uptake in hepatocytes. thus, heart and liver mitochondria show different levels of ca þ threshold and cooperative activation of ca þ uptake, which seem to result from differential quantitative relationship between micu and mcu. -pos board b er calcium release is

usa, department of physiology, semmelweis university, budapest, hungary. spatially and temporally controlled increases of h o emerge as an intracellular signal. we hypothesized that ros and ca þ interact locally, in the restricted vol- ume of the er-mitochondrial interface. these physically tethered structures host enrichments of ion transport proteins such as the ip receptor, which support elevated nanodomains of ca þ during signalling events and are sensitive to h o . we used the genetically encoded h o sensor hyper incorporated into an inducible linker system to probe the redox environment at the er- mitochondrial interface in hepg cells. we found a moderately elevated h o nanodomain which developes into a h o transient following ip receptor- mediated er ca þ release and mitochondrial ca þ uptake. pharmacological in- hibition showed that the transient was dependent upon er ca þ, mitochondrial membrane potential and functional electron transport chain. hyper measure- ments of the mitochondrial intermembrane space revealed significantly elevated h o within this volume. using electron microscopy we found that hepg mito- chondria possess a cohort of dilated cristae, which disappeared following ip - linked ca þ release. paxilline that inhibits mitochondrial bkca channels blocked the cristae reshaping and also abolished the h o transient at the inter- face. furthermore, paxilline caused suppression of the ip -linked calcium signal, whereas interface targeted killer red, a photoactivated h o source, induced sensitization to the ip -linked agonist. we conclude that the intermembrane/ cristae volume of mitochondria represents an oxidized pool fed by the electron transport chain. ca þ -uptake stimulates expansion of the mitochondrial matrix via kþ and concomitant water uptake, squeezing the oxidized volume of the cristae to the interface. here, a transient h o nanodomain sensitizes ip recep- tors to further stimulation. we demonstrate a physiological setting where ca þ release may autoregulate using mitochondrial h o released from the cristae. -pos board b reactive oxygen species (ros) suppress mitochondrial motility valentina debattisti, masao saotome, sudipto das, gyorgy hajnoczky. mitocare center, thomas jefferson university, philadelphia, pa, usa. mitochondrial distribution and transport play pivotal roles for many cellular functions, including cell differentiation, cell division to ensure proper inheri- tance, apoptosis, atp supply at the local sites of demand, ca þ buffering for intracellular ca þ homeostasis. we previously showed that mitochondrial motility (mito-motility) is regulated by the cytosolic ca þ concentration ([ca þ]c), providing the basis for a homeostatic circuit in which the organelles decrease their movements along microtubules to locally buffer high [ca þ ]c and contribute to atp supply. mito- chondria are also a major site for production and scavenging of ros that serve as both a messenger and regulator of calcium signaling and are particularly rele- vant for the control of mitochondrial function. here we tested the hypothesis that ros target mito-motility to control mitochondrial function. h c myoblast cells were transfected with a mitochondrial matrix targeted yfp and then loaded with fura , to monitor the mito-motility simultaneously with [ca þ ]c. h o ( mm) caused a decrease in mito-motility ( %) and an elevation in [ca þ ]c (from to nm) at the same time. when the cells were incu- bated in a ca þ -free medium and were pretreated with thapsigargin to prevent ca þ entry and intracellular ca þ mobilization, respectively, h o continued to inhibit the mito-motility dose-dependently without any changes in [ca þ]c. these results indicate that h o can cause suppression of mito-motility through a ca þ independent mechanism we are currently analyzing. -pos board b miro is dispensable for calcium-mediated inhibition of mitochondrial movement david b.

mitochondria and possess ef-hand calcium binding motifs. several groups have reported that miro is involved in mitochondrial motility and inheritance, and particularly its calcium regulation, but the roles of the two isoforms have not been established. genetic deletion of miro in mouse is lethal at birth (nguyen et al., ) and fibroblasts (mefs) derived from miro ko em- bryos show abnormal mitochondrial distribution, but the calcium-dependent in- hibition of motility is unaffected and the respiratory and calcium buffering capacities are normal. neuron-specific knockout of miro leads to progressive deficits of upper motor neuron function, however mitochondria in processes of cortical neurons from miro ko and wild-type embryos showed comparable calcium-sensitive motility inhibition. while no significant increase in miro pro- tein was observed in miro ko mefs, these data raise two possibilities: miro and are interchangeable with regard to calcium regulation of mitochondrial motility or miro is the key player in this regard. to finally resolve this question, we are in the process of generating miro ko and miro / ko cell lines. -pos board b mitochondrial fusion dynamics in

mitochondrial fusion dynamics in cardiomyocytes (cm), mitochondrial matrix-targeted photoactivatable gfp and dsred were intro- duced either in vitro or in vivo by adenovirus and were followed by confocal microscopy. four conditions were analyzed: to h cultured neonatal and in vitro transduced adult cm, and cm from in vivo infected rat hearts. in the latter case, cm were isolated - days after infection and were imaged promptly or - h post harvesting. neonatal cm mitochondria form a highly connected network, whereas both in vitro and in vivo transformed cultured cm displayed only some connectivity. impressively, in vivo transduced adult cm that were imaged promptly after harvesting, unveiled a significantly higher con- nectivity among mitochondria than the - h cultured adult cm. furthermore, fusion events (f.e./ square micrometers/min) were almost absent in cultured in vitro transduced cm, meanwhile in vivo transduced and cultured cm showed . . f.e./min, whereas isolated, freshly-imaged cm displayed . . f.e./min. imaging in perfused whole heart ex vivo, showed consider- able mitochondrial continuity and fusion activity in ventricular cm. to study more directly the role of cm’s contractile activity in mitochondrial fusion, cm were incubated with verapamil ( mm), that blocked spontaneous contrac- tion and partially suppressed the fusion activity of mitochondria. also, mito- chondrial fusion activity appeared to be higher after spontaneous contraction or short term field stimulation in isolated freshly-imaged cm. thus, mitochon- dria are dynamic in both neonatal and

carcinoma: an enigmatic entity with complex pathogenesis ulrich rodeck and jouni uitto expression of either collagen vii or the noncollagenous (nc ) fragment derived from it has been suggested to be indispensable for the development of squamous- cell carcinomas (sccs) in patients affected by recessive dystrophic epidermoly- sis bullosa (rdeb). this view is challenged here by the observation that sccs do develop in rdeb patients lacking expression of collagen vii altogether. the aggres- sive behavior of rdeb-associated sccs remains unexplained. journal of investigative dermatology ( ) , – . doi: . /sj.jid. the term epidermolysis bullosa (eb) represents a heterogeneous group of mechanobullous disorders characterized by skin fragility and blister formation. in addition to the skin, a number of other specialized epithelia, including the oral mucous membranes as well as those of the respiratory, vesicourinary, and gas- trointestinal tract, can be affected (fine et al., ). in milder forms of eb, blis- ters may be confined to limited areas of the skin, primarily the hands and feet. in contrast, in the most severe forms of eb, minimal trauma can result in widespread blistering and cutaneous erosions that heal slowly, if at all. the clinical course of the recessive dystrophic form of eb (rdeb, the hallopeau–siemens type; omim# ) is unrelenting, and the affected patients develop severe mutilat- ing scarring and are at high risk of devel- oping squamous-cell carcinomas (sccs) of the skin. unlike sporadic sccs in the general population, the rdeb-associ- ated sccs readily metastasize and have emerged as a prevalent life-threatening complication in these patients (fine et al., ). the cutaneous fragility in rdeb is caused by mutations in the col a gene, which encodes type vii collagen, a structural component of anchoring fibrils at the cutaneous basement membrane zone (varki et al., ). wild-type colla- gen vii contributes to the structural integ- rity of the basement membrane zone by tethering the lamina densa of the dermo- epidermal basement membrane to the underlying papillary dermis (shimizu et al., ). a wide spectrum of col a mutations that affect either collagen vii protein production or fibrillar assem- bly have been linked to deb. in rdeb patients, premature stop codons are frequently observed, predicting expres- sion of truncated collagen vii, including the noncollagenous (nc ) domain, but lacking c-terminal sequences nec- essary for collagen vii assembly. the molecular genetic hallmark of the most severe rdeb is stop codon mutations in both alleles, spanning the entire length of the collagen vii polypeptide (varki et al., ). ortiz-urda and colleagues ( ) recently demonstrated that expression of the nc fragment was required for malignant transformation of a series of keratinocytes isolated from rdeb patients. in addition, they observed that expression of either full-length collagen vii or the nc fragment was necessary for tumorigenic conversion of normal keratinocytes from non-rdeb individu- als. pourreyron et al. ( , this issue) revisited the requirement of collagen vii expression for scc development in another series of scc cell lines isolated from rdeb patients. they demonstrate that of patients investigated devel- oped scc in the absence of collagen vii or nc expression and conclude that, in rdeb patients, expression of collagen vii fragments is not a necessary requirement for scc development. in support of this notion, we have identified in the debra molecular diagnostics laboratory muta- tion database seven rdeb patients who were compound heterozygotes with two col a stop codon mutations in trans upstream from the nc /c junc- tion (varki et al., ). these patients are predicted not to express nc , yet two of three, who were over years of age, have developed aggressive sccs (j. uitto, unpublished observations). can these seemingly contradictory results be reconciled? the answer may lie in the use of distinct experimental systems that were employed to assess malignant transformation. ortiz-urda et al. ( ) based their study on the use of an experimental model system to assess the tumorigenic potential of normal kera- tinocytes. to achieve tumorigenicity in immunodeficient mice, they retrovirally transduced normal keratinocytes with oncogenic ras (ha-ras-v ) and the nf-κb inhibitor iκbα. thus, expression of collagen vii appears to be an absolute requirement for tumor formation driven by ha-ras, leaving open the question of whether this observation can be general- ized to rdeb patients. pourreyron et al.

her left pupil was smaller than the right. she also began to have visual scintillations. imaging a cervical spine mri shows no significant degenerative changes or disc herniations to explain the patient’s pain. however, there is an eccentric, crescent-shaped hyperin- tense signal encasing the anterior aspect of the left internal carotid artery on t - and t -weighted mri images, which is much more conspicuous on t imaging with fat sup- pression (fig. ). this finding is characteristic of a sub- intimal hematoma related to left internal carotid artery dissection. the proximal carotid arteries demonstrate a normal mri appearance for comparison (fig. ). clinical course the patient was brought to the hospital where she was evaluated by neurology and neurosurgery. she remained stable throughout treatment without signs of infarction or other complication from her internal carotid artery dis- section. although the spontaneity of our patient’s carotid dissection suggests a familial arterial disease, none has been confirmed. discussion there are many causes for neck pain, most of which are musculoskeletal in nature, including muscular or soft tissue etiologies, fractures, degenerative disc disease, and disc herniations. although relatively rare with an inci- dence of approximately in , , dissection of the carotid or vertebral arteries is an important cause of neck pain [ ]. craniocervical arterial dissection occurs more often in patients with familial arterial disease such as fibromuscular dysplasia. often, there is an inciting event, which can range from significant trauma to chiropractic maneuvers, or even minor events such as bending over. however, arterial dissection can rarely occur spontaneously. carotid artery dissection most often involves the extracranial internal carotid artery. it can present with a & brian reed curtis brian.curtis@jefferson.edu department of radiology, thomas jefferson university hospital, south th street, philadelphia, pa , usa sidney kimmel medical college, thomas jefferson university, philadelphia, usa intern emerg med ( ) : – doi . /s - - - http://crossmark.crossref.org/dialog/?doi= . /s - - - &domain=pdf http://crossmark.crossref.org/dialog/?doi= . /s - - - &domain=pdf partial horner’s syndrome with miosis and ptosis. miosis and oculosympathetic paresis are results of altered sym- pathetic pathways in the neck that normally contribute to pupil dilatation and partial elevation of the eyelid. in fact, one study reports that % of patients with internal carotid artery dissection presented with a painful horner syn- drome. furthermore, % have transient monocular vision abnormalities with scintillations, which our patient also eventually experienced, and this is attributed to choroidal hypoperfusion [ ]. these are important signs and symptoms to evaluate for while performing a history and physical examination on patients with neck pain. an mri is commonly ordered to evaluate neck pain, especially when there are neurologic symptoms, since its contrast resolution allows outstanding soft tissue charac- terization of disc herniations, nerve impingement and other common musculoskeletal disorders. clinicians may not suspect arterial dissection and dedicated vascular imaging may not be ordered;

with fast flowing blood create ‘‘flow voids’’ on mri that appear a black signal along the vessel course [ ]. this artifact is related to protons in the blood moving out of the region imaged in between the radiofrequency excitation pulse and the time that the excited protons relax, and release the radiofrequency that is measured to produce an image. this is a helpful artifact; if it is present, then the vessel can be considered patent, especially on t -weighted images. loss of a flow void can represent vascular occlusion or slow blood flow. our patient maintains a flow void in her left internal carotid artery indicating luminal patency, but there is an abnormal signal surrounding its anterior aspect on t - and t - weighted images. hyperintense signal on t -weighted images is caused by few materials found in the human body including blood products, fat, melanin, proteinaceous material, calcification and other mineralization. in vascular dissection, a tear in the tunica intima allows blood to dis- sect into the sub-intimal space and into the tunica media. extravascular blood products evolve from hemoglobin to methemoglobin, a change that is observed by signal intensity change on mri. subacute hemorrhage with methemoglobin appears bright on t images; this is seen around days after the formation of the initial hematoma, and remains up to months [ ]. the crescent-shaped t hyperintensity surrounding the anterior aspect of the left internal carotid artery is diagnostic of a sub-intimal hematoma related to a tear in the tunica intima that remains contained by the tunica adventitia. this finding is con- firmed and more conspicuous on t fat-saturated images, since the abundant normal t hyperintense fat is darkened and t hyperintense blood products remain bright. this can easily be overlooked on mri, especially without fat- suppressed t images (which are not typically included on routine cervical spine mri images), if the vessels are not diligently evaluated.

understood disease. the literature is lacking with respect to the epidemiology of patient comorbidities and their effect on gastric emptying. we aimed to describe the most common comorbid conditions among patients with gastroparesis in an urban population and quantify the effect of these comorbidities on the severity of delayed gastric emptying (dge). methods we examined the medical records of all patients diagnosed with gastroparesis at a quaternary care center between and . the severity of dge was analyzed after patients were stratified for possible causative etiologies. likelihood ratio tests were used to assess the significance of demographic and scintigraphic variation in this population. results of the patients, . % were caucasian and . % were african american. among these patients, . % had evidence of medication-associated gastroparesis, . % had diabetes- associated gastroparesis, and . % had idiopathic disease. african american patients with gastroparesis were more likely to have diabetic gastroparesis than patients of other races (p= . ). there was a statistically significant relationship between the number of major risk factors and the severity of a patient’s dge (p= . ). conclusions among a diverse urban population, patients with dge often carry multiple comorbid conditions that serve as risk factors for the development of gastroparesis, including prescriptions for narcotic medications. greater numbers of these comorbid conditions are associated with more severe disease. demographics are significantly associated with the etiology and severity of gastroparesis; in particular, african american patients are more likely to have diabetic gastroparesis than patients of other races. keywords delayed gastric emptying, diabetes mellitus, narcotic

bloating, and upper abdominal pain, and in the absence of a mechanical obstruction [ , ]. the gold standard for diagnosis is gastric emptying scintigraphy (ges)  [ , ]. the epidemiology of gastroparesis in the community is not well described. two previous studies have described the epidemiology of the disease, but these were limited to relatively uniform suburban and rural locations [ , ]. while a multitude of etiologies of gastroparesis have been suggested, most studies group patients into categories: diabetic and idiopathic. diabetic gastroparesis has been extensively studied [ -

comorbidities among an urban patient population diagnosed with gastroparesis and to determine whether certain comorbidities correlate with disease severity. patients and methods this is a retrospective chart review including all patients who underwent ges at thomas jefferson university hospital in philadelphia, pa, between and . this study was evaluated and approved by the institutional review board at our institution (control # d. ). the electronic medical record was reviewed to collect information regarding patient demographics, medical history, medications prescribed

their ges showed > % retention of gastric contents h following ingestion of a solid meal consisting of an egg and bread sandwich labeled with . mci of technetium m-sulfur colloid. this is the standard for diagnosing dge at our institution; it is based on industry standards for the philips medical systems’ jetstream software as well as institution-specific analyses. patients were excluded from the presented analyses if they had a mechanical gastric outlet obstruction precluding the diagnosis of gastroparesis. the presence of comorbid conditions serving as risk factors for the development of gastroparesis was evaluated for each patient in the study population. major risk factors were defined as comorbid conditions that have been well established in the literature to be strongly associated with gastroparesis. minor risk factors were defined as those postulated to be related to gastroparesis in in vivo studies or smaller case reports, but not consistently proven to be associated. patients were assigned to categories as outlined in fig. ; patients with one or more major risk factors were assigned to the appropriate mutually inclusive groups - , while patients with minor risk

there was significant demographic variation among the etiologic categories. in a model comparing patients with and without diabetes- associated gastroparesis, patient race (p= . ), age (p= . ), sex (p= . ), and bmi (p< . ) were independent, statistically significant predictors of having diabetes-associated gastroparesis. while only . % of the study population was african american, . % of patients with diabetes-associated gastroparesis in this population were african american. men, patients with an elevated bmi, and patients diagnosed at an older age had a statistically significantly greater probability of having diabetes-associated gastroparesis than females, patients with a lower bmi, and younger patients (tables , ). in a model comparing patients with and without medication-associated gastroparesis, age (p= . ) and bmi (p= . ) were independent, statistically significant predictors of having medication-associated gastroparesis after controlling for patient sex and race. patients with a higher bmi or diagnosed at an older age had a higher likelihood of having medication-associated gastroparesis than patients with a lower bmi and those younger at diagnosis. among patients with idiopathic disease, there was also a statistically significant variation in age (p< . ) and bmi (p= . ) compared to patients in the study population without idiopathic disease after controlling for sex and race. patients with a lower bmi or those diagnosed at a younger age were more likely to have idiopathic disease than patients with a higher bmi or those older at

least one risk factor for gastroparesis, while % of patients had true idiopathic disease. a higher burden of major risk factors was significantly associated with a more severe delay in gastric emptying. to our knowledge, this is the first study to examine the comorbidities, or risk factors for dge among an urban population of gastroparesis patients, and the first to attempt to establish the impact of multiple comorbid conditions on the objective severity of dge. our patient demographics are similar to those in previous publications with regard to the average age of patients at the time of diagnosis and the k. duffeya et al annals of gastroenterology previous studies have attempted to correlate patient symptoms with the degree of dge, but few have examined the relationship between etiology of gastroparesis and the severity of dge [ - ]. we have shown that patients with diabetic or medication-associated gastroparesis and those with multiple major risk factors in combination had significantly more severe dge compared to those with idiopathic gastroparesis. a wide range of medications have been implicated in delaying gastric emptying. based on the available evidence, we considered narcotic analgesics and anticholinergic medications to be significantly related to dge [ - ]. in our study, % of patients had an active prescription for narcotics at the time of diagnosis – higher than the national opioid prescribing rate [ ]. calcium channel blockers and tricyclic antidepressants are thought to impact gastric motility, but data are lacking on a clear relationship with dge [ - ]. for this reason, we considered both of these medications to be minor risk factors for the disease. a majority of our patients had a prescription for at least one medication that has been implicated in delaying gastric emptying, a finding that has not previously been well described. according to the consensus recommendations for gastric emptying scintigraphy, most centers recommend that patients stop gastric motility-delaying agents - h prior to undergoing ges [ ]. perhaps it could be beneficial to perform ges while patients are still taking all medications; this would provide the most accurate representation of the patient’s dge as it occurs on a daily basis. table race and risk factors patient group total race (%) p-value* caucasian african american other overall . . . na

diabetes mellitus in the community are also greater among african americans ( . vs. . % for caucasians) [ ], our findings indicate a disproportionate impact on minority populations. medical conditions that have been clearly linked with gastroparesis include post-surgical nerve injury, parkinson’s disease, autoimmune diseases and connective tissue diseases, such as systemic sclerosis and sjögren’s syndrome [ , - , , - ]. interestingly, our population included a significant percentage of patients with hypothyroidism ( . %), significantly higher than the national prevalence of . % [ ]. while the hypothyroidism state is associated with delayed esophageal and gastric motility, we did not consider a diagnosis of hypothyroidism to be a major risk factor for gastroparesis, as evidence suggests that once patients are stabilized on appropriate medication, the impact on motility is typically resolved [ - ]. idiopathic gastroparesis is diagnosed when no other cause is identified, though it is often unclear in previous studies which potential causes were considered before patients were labeled with the diagnosis [ , , ]. as is standard in the literature  [ - ], we included patients with a post-viral syndrome as patients with idiopathic disease, assuming that they did not have a major risk factor. in our study, we relied on the available literature to describe exposures and comorbid conditions as risk factors for gastroparesis. our individual patient data were limited to the availability of details in the medical record. we were unable to gather information regarding indicators of the severity and control of patients’ underlying chronic diseases, or the doses of their prescribed medications, both of which can impact gastric emptying. in addition, the gold standard for evaluation of dge is -h nuclear emptying scintigraphy. however, at our institution patients classically undergo a -h scan unless there is doubt regarding the results. finally, it is difficult to determine which medications were held prior to scintigraphic testing and for how long. these patient instructions are physician- dependent and there is no clear documentation in our record system regarding the instructions provided to the patient or followed by the patient. in conclusion, the results of this retrospective study indicate that patients diagnosed with gastroparesis often have multiple comorbid conditions, and the number of risk factors that they carry significantly impacts the severity of their disease. if we continue to limit patients into broad categories of diabetic and idiopathic gastroparesis, we may be missing opportunities to better address the true underlying etiology of the disease and to treat patients optimally. in addition, we have demonstrated a racial disparity in the etiology of gastroparesis, with african american patients being more likely to have diabetic disease than patients of other races. further research should be done to better elucidate the impact of certain medications, comorbid conditions and socioeconomic status on gastric emptying. additionally, physicians should consider patients’ individual risk factors when ordering, protocoling, and interpreting ges studies in order to best evaluate the extent of the disease and to provide optimal medical management. summary box what is already known: • little is known about the causes of gastroparesis beyond severe diabetes • many patients are characterized as having idiopathic gastroparesis what the new findings are: • a large proportion of gastroparesis patients receive narcotic prescriptions • african american patients seem to be at higher risk for diabetic gastroparesis than patients of other races • patients with more conditions known to be associated with gastroparesis had more severe objective delays in gastric emptying references . camilleri m, parkman hp, shafi ma, abell tl, gerson l; american college of gastroenterology. clinical guideline:

work, we use density gradient centrifugation and liposome coflotation analysis to demonstrate that the anchoring energy of the dengue e protein in anionic membranes composed of popcþpopg is much greater than in membranes composed of popcþpope. -pos board b hiv fusion peptide perturbs membrane structure in a cholesterol dependent fashion alex liqi lai, jack h. freed. acert, cornell university, ithaca, ny, usa. the fusion between viral envelopes with host cell membranes is required for viral entry and infection, which is mediated by special glycoproteins anchored on the viral membrane. fusion peptide (fp) is the domain that initiates mem- brane fusion. however, the mechanism of membrane fusion is still unclear. we previously found that the influenza hemagglutinin fp increases the order of dmpc lipid bilayer. we hypothesize that inducing lipid ordering might be a critical step in fusion caused by a variety of fusion proteins. hiv gp fp plays a similar role as influenza ha fp. however, gp fp is polymorphic and changes from alpha helix to beta aggregation as cholesterol concentration in lipid increases. we used pc spin labels on the lipid head group and different positions on the acyl chain to detect the perturbation by gp fp to popc/ popg lipid bilayers with different cholesterol concentration ( % to %) by cw-esr. our data show that ) gp fp affects the lipid order in the same pat- tern as ha fp does, i.e., a cooperative effect vs. lipid/peptide ratio, thus sup- porting our hypothesis; ) gp fp induces membrane ordering in all tested lipid compositions, consistent with promoting membrane fusion in these com- positions; ) in the high cholesterol containing lipid bilayers, whereas gp fp is in the beta aggregation conformation, its effect on the lipid ordering reaches deeper into the bilayer, consistent with deeper membrane insertion for gp fp in this conformation. we are extending the esr studies to look for coexisting membrane microdomains induced by different conformations of fps and the fp partitioning between them and for precise separation of the effects of ordering and molecular motion. -pos board b cd binding induces an asymmetric transition of hiv- env from its native conformation into the prehairpin intermediate state mukta d. khasnis, konstantine halkidis, anshul bhardwaj, michael root. thomas jefferson university, philadelphia, pa, usa. hiv- membrane fusion is mediated by sequential binding of the viral homo- trimeric env (gp /gp ) to cellular cd and chemokine receptor (cxcr or ccr ). these binding events coordinate conformational transitions of the gp trimer from its native conformation into a prehairpin intermediate state (phi) and, subsequently, into its fusogenic trimer-of-hairpins structure (toh). in the phi, the gp trimer assumes an extended conformation that bridges the viral and cellular membranes, and exposes the n-hr and c-hr do- mains which are targeted by hiv- fusion inhibitors t and -helix, respec- tively. our previous work suggests that the phi-to-toh transition occurs in a concerted (symmetric) fashion. here, we investigate the transition from the native state to the phi using a functional complementation strategy that em- ployed heterotrimeric envs containing only one or two functional cd - and chemokine receptor-binding sites. additionally, by incorporating t - and -helix- resistance mutations into individual env protomers, we were able to interrogate exposure of discrete gp n-hr and c-hr domains. our data indicate that a single cd binding to an env trimer is sufficient to promote fusion. moreover, the first cd binding event appeared to expose only one of three possible binding sites for each fusion inhibitor, suggesting an asymmetric transition into the phi. this asymmetry was significantly more pronounced in the gp n-hr region compared to the gp c-hr region. these results can be used to explain the multiphasic titration of mutant env homotrimers that naturally form asymmetric n-hr domain structures. taken together, these data suggest that the native state-to-phi transition of env occurs in a multistep (asymmetric) fashion. -pos board b evolution of hiv- resistance to a cholesterol-linked d-peptide fusion inhibitor amanda e. siglin , nicholas francis , michael s. kay , micheal j. root . thomas jefferson university, philadelphia, pa, usa, university of utah, salt lake city, ut, usa. during hiv- entry, the n-hr and c-hr regions of the gp viral glycoprotein associate to form a trimer-of-hairpins critical for membrane fusion. the n-hr region contains a highly conserved hydrophobic pocket that is the target for a multivalent, d-peptide fusion inhibitor, pie -trimer. recently, a modified form of this inhibitor with a conjugated cholesterol (chol-pie -trimer) was shown to possess up to -fold increased potency, presumably due to mem- brane targeting. here, we determined the resistance profile of chol-pie - trimer starting from either inhibitor-naı̈ve or pie -trimer-resistant hiv- (nl - strain). viral propagation in increasing inhibitor concentrations pro- duced hiv- populations with - to -fold reduced sensitivity chol- pie -trimer. these viruses were also resistant to the parental, unconjugated inhibitor pie -trimer. using hiv- fusion inhibitors di-c and -helix, we were able to interrogate the effect of escape mutations on the exposure of the gp n-hr and c-hr regions, respectively. resistance to chol-pie - trimer resulted in a slight decrease in the temporal window of n-hr exposure, regardless of the starting viral population. exposure of the c-hr region was unchanged for resistant viruses generated from the inhibitor-naı̈ve viral pool. by contrast, the temporal window of c-hr exposure was significantly increased (> -fold) for resistant viruses that were generated from the pie -trimer-resistant viral pool. efforts to identify the mechanisms of chol- pie -trimer resistance and the decoupling of n-hr and c-hr exposure are underway. -pos board b fusogenic activity of the hiv- gp mper-tmd region: mechanism and targeting by immunogens and inhibitors jose l. nieva , beatriz apellaniz , carmen domene , nerea huarte , eneko largo . biophysics unit (csic-upv/ehu) and dept. of biochemistry, university of the basque country (upv/ehu), bilbao, spain, chemistry research laboratory, university of oxford, oxford, united kingdom. fusion of the viral envelope with the cell membrane marks the beginning of the hiv- replicative cycle. this event is targeted by inhibitors currently in clinical use and by preventive vaccines under development. antibodies e and e bind to the gp membrane proximal external region (mper)- transmembrane domain (tmd) junction and block fusion. these antibodies display the broadest viral neutralization known to date, which underscores the conservation and functionality of the mper-tmd region. in recent work, we have described that peptides representing this region have potent membrane-destabilizing effects. here, based on the outcome of vesicle assays, atomic force microscopy studies and molecular dynamics simulations, we propose a mechanism for the involvement of the mper-tmd region in hiv- fusion. in addition, we provide evidence that underpins the poten- tial use of its activity as a new target for inhibitor and immunogen development. -pos board b studies on the membrane-active behavior of outer membrane vesicles from a gram negative bacterium william bartos, rensa chen, donald y. kobayashi, paul r. meers. rutgers, the state university of new jersey, new brunswick, nj, usa. gram-negative bacteria are known to produce small ~ - nm vesicles by ‘‘blebbing’’ of their outer membranes. these outer membrane vesicles (omv) have been implicated in activities such as transmission of virulence fac- tors, horizontal gene transfer and development of biofilms. in this investigation, the interactions of omv from lysobacter enzymogenes (strain c ) with other membranes have been monitored using fluorescent assays for association and/or fusion. defined composition large unilamellar vesicles labeled with the fluorescence resonance energy transfer (fret) pair , -dipalmitoyl-sn- glycero- -phosphoethanolamine-n-( -nitro- - , -benzoxadiazol- -yl) (nbd- pe) and , -dipalmitoyl-sn-glycero- -phosphoethanolamine-n-(lissamine rho- damine b sulfonyl) (rh-pe) were incubated with isolated omv to observe the interaction via the fret ratio of donor/acceptor. omv substantially increased this ratio over the course of about an hour (t / ~ - min.) at �c, when added directly to vesicles comprising disordered or fluid lipids, such as -palmitoyl- -oleoyl-sn-glycero- -phospho-( ’-rac-glycerol) (popg), -pal- mitoyl- -oleoyl-sn-glycero- -phosphoethanolamine (pope) or -palmitoyl- - oleoyl-sn-glycero- -phosphocholine (popc). this apparent fusion was much more limited or absent with liquid ordered membranes of , -dipalmitoyl-sn- glycero- -phosphocholine/cholesterol (dppc/chol). in the case of popg/ pope / vesicles, apparent fusion was also confirmed by testing vesicles with exclusively inner monolayer fluorescent probes to diminish any fluores- cence changes from external interactions of outer monolayer fluorophores. when the omv were labeled with the fluorophore , -dioctadecyl- , , , - tetramethylindocarbocyanine, and incubated with a natural host, yeast cells (strain s ), association and/or fusion was observed by co-sedimentation of the omv label with yeast cells. these studies may help to elucidate the mech- anism of natural host-pathogen interactions and define the lipid specificity for hiv fusion peptide perturbs membrane structure in a cholesterol dependent fashion cd binding induces an asymmetric transition of hiv- env from its

gpcr kinases and �-arrestins may be useful in the treatment of asthma. in this paper of the week, a team led by jeffrey benovic at thomas jefferson university screened lipidated pep- tides from the intracellular loops of the � ar, known as pepducins, and discovered two types of biased activa- tors of � ar signaling. one type was a receptor-dependent pepducin that stabilized a conformation of the

invasion: consequences of potential needle-tract seeding from fine-needle aspiration richard zheng, ,* sami tannouri, and harish lavu , abstract background: pancreatic neuroendocrine tumors (pnets) are relatively rare, and data guiding management of metastatic lesions are scarce. hepatic metastases are most common; here we describe a case of metastatic pnet implanted into the posterior gastric cardia. case presentation: this case study describes the progression of a -year-old man with a history of pancreatic neuroendocrine tumor (pnet) resected through distal pancreatectomy and splenectomy who developed recurrent disease in his stomach with extension into the left adrenal fossa months after initial resection. he subsequently underwent a total gastrectomy and left adrenalectomy with en bloc resection of this recurrence without compli- cation. final pathology revealed a morphologically similar pnet with positivity for cam . , chromogranin a, and synaptophysin. conclusion: the unusual location of his recurrence could suggest that his preoperative endoscopic ultrasound and fine-needle aspiration may have had a role in seeding the posterior gastric wall, highlighting the risk of per- forming this diagnostic procedure in the setting of suspected pancreatic malignancy. keywords: metastatic pancreatic neuroendocrine tumor; pnet introduction pancreatic neuroendocrine tumors (pnets)

(fig. ). endoscopic ultrasound was performed with fna of the pancreatic mass. histopathological review of the fna sample revealed neoplastic cells, positive for anti-pan cytokeratin antibody, synapto- physin, and cd , suggesting pnet. an octreotide scan showed focally increased signal at the site of the pancreatic mass, without dissemination. the patient underwent resection of the tumor through distal pancreatectomy and splenectomy with en bloc por- tal vein resection and reconstruction as the tumor was di- rectly invading the splenic vein with thrombus extending into the portal vein. the patient tolerated this procedure well and his postoperative course was uncomplicated. pathology from this initial procedure revealed a grade ii pnet with / adjacent lymph nodes positive for metastatic carcinoma and negative margins with a ki- proliferative index of % (grade ii). seventeen months after resection, the patient began to have complaints of fatigue, exercise intolerance, and pal- pitation. he was again found to be anemic with a hemo- globin of . g/dl. before the aforementioned initial resection, serum pancreatic polypeptide and chromogra- nin a levels had been elevated to pg/ml and . ng/ ml, respectively; with the onset of these new symptoms, the pancreatic polypeptide level was found to be only pg/ml, but the chromogranin a level was elevated to ng/ml (fig. ). ca – levels remained normal throughout the patient’s full treatment course. diagnos- tic endoscopy to localize the source of bleeding revealed a cm malignant-appearing friable mass with central ulceration in the gastric cardia. ct scan findings con- firmed the presence of this gastric soft tissue mass and also revealed a posterior nodular extension toward the upper pole of the left kidney (fig. ). this lesion demon- strated uptake on octreotide scan, suggesting a pnet origin; a focus of uptake was also noted in the periportal region, suggesting the possibility of a metastatic lymph node. upon histopathological review of the material re- trieved at the endoscopy, the gastric lesion was identified to be morphologically similar to his previous pnet, with positivity for cam . , chromogranin a, and synaptophysin. after extensive discussion with the patient regarding his treatment options, he opted for reresection through an open total gastrectomy. after exploratory laparotomy and extensive lysis of adhesions, the tumor was noted to invade into the capsule of the left adrenal gland. both the stomach and the left adrenal gland were removed en bloc. no hepatic lesions were noted. alimentary tract recon- struction was performed through a roux-en-y esopha- gojejunostomy. the periportal region was skeletonized with removal of all nodal tissue. the patient’s postoperative course was uncomplicated. he was ultimately discharged to home on postoperative day on a low-volume clear liquid diet and total parenteral nutrition supplementation. surgical pathology revealed a pancreatic neuroendo- crine carcinoma in the gastric wall and adrenal gland with negative resection margins. the sampled peripor- tal lymph nodes were free of disease. the lesion was again confirmed to be morphologically similar to the patient’s previous pnet (fig. ). shortly thereafter, pancreatic polypeptide and chromogranin a normal- ized to pg/ml and ng/ml, respectively. fig. . hypervascular

documented in the literature. surgical resec- tion remains the gold standard of treatment for func- tioning and nonfunctioning tumors. management of these metastases has not yet been standardized. surgi- cal management of hepatic metastases through partial hepatectomy has been shown to control symptoms of hormonal hypersecretion in patients with functional tumors and improve overall survival. hepatic-directed therapy such as transarterial chemoembolization has also been utilized for control of liver metastases. fig. .

to ours was described in . in that re- port, a -year-old man was found to have a t n m moderate-to-well differentiated pancreatic adenocarci- noma sampled through eus/fna biopsy through the stomach wall. nine months after resection of the lesion, the patient was found to have a submucosal gastric re- currence upon follow-up endoscopy. this was man- aged through a subtotal gastrectomy, whereupon final pathology demonstrated a morphologically identical le- sion to his initial cancer. in comparison, our lesion had expanded aggressively into the retroperitoneum and appeared to involve the adrenal gland, so a total gas- trectomy and en bloc adrenalectomy were required for full resection. furthermore, as in the previously mentioned case report, fna played an important role in the preliminary diagnosis of pnet. given the atyp- ical foci of recurrence in the gastric cardia, this scenario brings to mind the rare phenomenon of needle-tract seeding that has been documented in sarcoma, prostate cancer, hepatocellular carcinoma, and other lesions. despite the theoretical fears of needle-tract seeding, however, data validating this phenomenon with regard to some forms of pancreatic cancer are generally limited to case reports. , furthermore, this is the first report of a pancreatic neuroendocrine neoplasm recurrence poten- tially from needle-tract seeding. a retrospective study of patients who underwent surgical resection of ma- lignant pancreatic neoplasms concluded that undergoing eus/fna of these lesions was not associated with a sta- tistically significant increase in the rate of either perito- neal or gastric metastases. similarly, use of eus/fna for diagnosis of pancreatic cancer was not associated with any difference in survival. multiple studies have also corroborated that the use of eus/fna for both pan- creatic cancer and intraductal papillary mucinous neo- plasm sampling was not associated with a statistically significant increase in peritoneal seeding when com- pared with patients who were not sampled. , alternative approaches for tissue sampling of pancreatic masses have not proven to be of benefit; one study demon- strated an increase in the rate of peritoneal carcinomato- sis in patients who had undergone a percutaneous fna when compared with those who had endoscopic tissue sampling. although large-scale data on pancreatic nee- dle biopsy seeding is yet unavailable, it is likely a rare occurrence as needle biopsy of pancreatic lesions is com- monplace and gastric metastases are seldom seen. in most cases, the benefits of direct tissue diagnosis out- weigh the theoretical risk of needle-tract seeding. however, no matter how remote the chance for seed- ing may be, it is up to clinicians to be selective in obtaining biopsies of lesions where a tissue diagnosis may change management and not subject a patient to undue risk. in this particular case, one could ques- tion the utility of two interventions before the initial operation—the distal pancreatectomy and splenecto- my: the fna done as part of the eus, and the octreo- scan. the patient had a classic appearance of a pnet on ct and mri, and he was symptomatic from anemia related to splenic vein occlusion. did the fna results alter management? did the octreoscan provide essen- tial information? in this era of cost consciousness in surgical care, we need to be asking these questions. author disclosure statement no competing financial interests exist. references . ikezawa k, uehara h, sakai a, et al. risk of peritoneal carcinomatosis by

online, a digital initiative of the national historical publications and records commission (nhprc) of the united states national archives, launched in june . designed and updated by david sewell and his staff at the university of virginia press, the site is an essential resource for scholars of early american history. since its debut, the site has attracted over a million visitors interested in learning more about the creation of the united states of america in the words of six of its “founding fathers”: george washington, john adams, thomas jefferson, james madison, benjamin franklin, and alexander hamilton. with over , letters or other writings of these men and their contemporaries who corresponded, lived, and worked with them, the site utilizes extensible markup language (xml) encoded documents hosted on a marklogic server to provide free, fast, and user- friendly access to the public. founders online has received praise from the larger scholarly community, including the society for history in the federal government, kurtz: founders online which awarded the site its prestigious thomas jefferson prize for its “outstanding contribution” to scholarship (ferriero b). this emphasis on reaching a much larger audience than documentary editors have traditionally served, the academic historian, should be considered a model for future digital editions regardless of their scale or subject. as stephen pinfield argued, “the major question associated with open access is no longer whether oa [open access] should be at the centre of the mainstream scholarly communication system, but how?” (pinfield ). as an assistant editor at documents compass, a program of the virginia foundation of the humanities that helps documentary editors publish their work digitally, i helped to manage the early access portion of the project from to . relying on a paid staff of over thirty people, most of whom had little experience in historical or digital work prior to joining our team, we transcribed or proofread over , early access documents. these temporary documents, meant to give the american public an early look at transcripts of historical documents not yet finished by the documentary editing projects, will eventually be replaced by permanent, professionally vetted and annotated versions. our project was led by documents compass director, susan h. perdue, with assistant editor laura k. baker and myself serving as project managers. the lessons i learned in managing our large staff and in working with a variety of editing projects with different editorial policies and methodological approaches suggest several best practices for other digital humanists considering crowd-sourcing projects utilizing volunteer labor or hoping to impose standardized metadata and workflow procedures when aggregating different projects under one digital roof. digital history meets documentary editing the appeal of publishing humanities work digitally cuts across disciplines and has increasingly become a priority for faculty hiring, cultural institutions hoping to celebrate and grant greater access to their holdings, and for scholars seeking to reach for more information on the technical infrastructure that hosts founders online, please see matt allen, “founder’s online: a lesson in performance” (allen ) and “founders online launches” (uva ). kurtz: founders online new audiences. in the field of history, the importance of writing and producing historical scholarship accessible beyond the walls of academia has become increasingly important even for those who do not consider themselves strictly public historians. in an era of decreasing faculty and research budgets for the humanities, proving that the study of history is valued by the american public is vital for history departments, universities, museums, and other historical entities that rely on public monies to cover their expenses. certainly projects such as the university of richmond’s atlas of the historical geography of the united states and american panorama have demonstrated that digital history can have a wide appeal beyond academia (stinson ). the value of publishing online is an important and ongoing debate within the historical subfield of documentary editing. founding-era documentary editing projects explore the lives of some of the most famous and important figures in united states history. the papers of thomas jefferson, begun in under the direction of renowned editor and historian julian p. boyd, is widely considered to be “the first modern historical documentary edition.” this project established standard guidelines and editorial practices that have strongly influenced other documentary editions (founders online a). by transcribing and annotating the complete works and correspondence of men such as jefferson, adams, and washington, these editorial projects are engaged in some of the most worthwhile publicly-funded historical work. a variety of private and government funders, most notably the nhprc and the national endowment for the humanities, have provided millions of dollars to make these projects possible and continue to be important funding sources today (founders online c). the tireless efforts of project editors and staff to provide accurate and scholarly editions of these men’s writing, however, are both time consuming and costly. in addition, the high cost of publishing their works in print ensures that only relatively few volumes are produced on a yearly basis. this means that the american public, which has demonstrated time and again its interest in the story of the creation of for a good discussion of the value of digital history, how it differs from traditional scholarship, and how it allows historians to reach wider audiences, see “a conversation with digital historians” (southern spaces ). kurtz: founders online its nation, has limited opportunities to benefit from this important work. while the most important editions did start to go online in the early st century, these projects, such as university of virginia press’s subscription-based service founding era collection, often existed behind a paywall that limited their use to universities able to pay for access (uvap founding era collection ). a digital edition success story: founders online founders online was a congressional initiative to fix this problem (senate hearing , – ). proposed in , funded in , and launched three years later in the summer of , founders online made freely available online some of the most important editions of the founding fathers. the site provides an intuitive search interface and the ability for anyone with an internet connection to access the letters and writings of george washington, john adams, thomas jefferson, james madison, alexander hamilton, and benjamin franklin. the site not only opened up these resources to universities who could not afford rotunda, but it also made access to the documents that explain the creation of the american republic easily available to k- educators and their students as well as the larger american public. the national archives underscored its goal of opening these documents to new audiences, particularly to educators, by having students participating in the national history day contest in washington, d.c., in attend the launch of the founders online website. these students demonstrated its use to an audience of editors, archivists, politicians, and journalists. since its launch, the site has attracted over one million visitors both inside and outside of the academic and scholarly history communities (national archives, , , and a). founders online’s simple site design, with a central search bar resembling google’s search engine page, is meant to make using the site and its historical documents as user friendly as possible. designed by the ivy group of charlottesville, virginia, the website was user tested on several occasions. in addition to ivy group’s user testing, students at bishop o’connell high school in arlington, virginia, also tested the site to assess its user friendliness for k- education. the site’s filters allow users to restrict searches by author, recipient, and date, and its recent addition of teaching resources highlighting important documents on specific subjects such kurtz: founders online as the louisiana purchase, native americans, and women, are all aimed at helping the non-specialist explore the site as easily as possible. this emphasis on the non- academic user sets founders online apart from other digital projects (ivy group ; national archives b; founders online b). founders online has proved useful to scholars and the general public in both expected and surprising ways. on accepting the thomas jefferson prize, archivist of the united states david ferriero lauded the many ways in which the site had been used since its launch. he noted that it was cited in articles in the prestigious historical journal, the american historical review, as well as a number of academic monographs such as joel kavorskey’s the true geography of our country: jefferson’s cartographic vision (uvap ). historian peter s. onuf’s popular massive open online course (mooc), “the age of jefferson,” made extensive use of documents on founders online as part of its required reading material (age of jefferson ). the archives’ own educational website, docsteach.org, links directly to founders online transcripts, and the national humanities center also helped to create lesson plans utilizing the site’s resources for k- teachers (docsteach ; ferriero a). users beyond historians have utilized letters on founders online in other exciting ways. anna berkes, a research librarian at monticello, has used the website to help expose fabricated quotations commonly attributed to thomas jefferson. the u.s. supreme court cited a document on founders online in its decision in the nlrb v. noel canning case. perhaps the most creative use of the site was by a composer and professor at the berklee college of music, gates thomas, who composed a cantata based on a letter by george washington. perhaps most gratifying has been the feedback from the many users of the site who have helped to identify a small number of errors, either in transcription or annotation, that have come to light and are easily fixed by uva press staff thanks to the site’s free and digital publication apparatus. founders online thus serves as a model for the digital history and humanities communities to reach larger audiences and shows the benefits of funding humanities research (walters ; supreme court ; with good reason ). https://www.docsteach.org kurtz: founders online early access: challenges in project management founders online’s emphasis on a user friendly experience is complimented by its creators’ decision to showcase early access documents that have not been fully vetted by professional editors. whereas most projects wait to publish letters only after they have been fully annotated, a decision was made early on that the american public should have access to over , documents that have yet to be completed by their relevant documentary editing project’s staff. thus the early access project was created to transcribe and proofread these documents, which will be temporary placeholders until professionally edited and annotated versions are completed. these early access letters provide insight into important parts of the founding fathers lives that the site’s users would have otherwise been without for many years. transcribing or proofreading these early access documents would not have been possible without the nhprc’s desire to give the american public access to as many documents as possible as quickly as possible (national archives ). in , documents compass received a contract from the u.s. national archives to complete a pilot project to show whether providing early access to unpublished letters was feasible. directors susan perdue and holly shulman, both veterans of the field of documentary editing and leaders in publishing digital editions, proved that the project was indeed possible, leading to a second contract awarded in . the early access project officially began on january and finished in december . the project employed a large staff of proofreaders, sometimes numbering over temporary or graduate student employees, working under the direction of myself and my colleague, laura baker. our proofreaders generally had degrees in the humanities and social sciences but were not experts in th century handwriting, history, politics, or culture. by the end of the project, however, they developed an ability to read even the most difficult penmanship and gained a much deeper understanding and appreciation for the founding fathers and their times. a number of them gained exceptional technical and editorials skills, which they used to help me reconcile data in our various databases, locate and digitize letters from kurtz: founders online microfilm, and conduct basic historical research to try to ensure our transcriptions’ accuracy. given that our staff was largely inexperienced in editing or historical work, we designed our processes to help ease employees through the various technical aspects of their work. for example, few of them had any experience with editing in xml. we realized that we needed a user-friendly xml software such as xmetal, a program whose interface closely resembles that of microsoft word. we found that the more popular and familiar program, oxygen, even in its out-of-the-box “author” view, was too technical and difficult for most of our staff. we also had to train our employees in the unique style guides employed by each project. we created instructions and processes that were simple and understandable in order to produce the best quality transcripts possible while adhering as closely as possible to project specific requirements. despite our limited time and ambitious goals, varying accessibility of manuscript sources necessary for transcription and proofreading, and the different requirements and methods of each project, we believe that by the end of our project our employees had improved their speed and accuracy considerably. our proofreaders benefited from regular in-person and online feedback about their work from our project managers, and, as they gained experience, they became more adept at deciphering late th and early th century handwriting. they mastered the basics of xml editing and utilized historical techniques such as using other letters to decipher difficult words or using online resources to look up basic information about people, historic places, and past events. ultimately, our staff produced here, i would like to recognize early access team members mark hawking, jeffrey diehm, dena radley, jeffrey zvengrowski, and james ambuske for their exceptional contributions to the project. several of our proofreaders were so moved by their experience that they took part in a special episode of with good reason, a public radio show featured locally on national public radio (npr), in order to tell the wider community of their newfound appreciation for early american history (with good reason ). for example, our first goal was to proofread and publish , letters from the papers of george washington and papers of james madison projects. both projects have unique style guides of differing complexity and specificity about how to handle superscripts, double punctuation, capitalization, etc. the need to train employees simultaneously in two different style guides greatly increased the difficulty of our work. kurtz: founders online preliminary transcripts that will be useful to founders online’s users as they wait for the documentary editing projects to complete their work. lessons from early access my experience in founders online: early access not only convinced me of the importance of taking into account a larger, non-academic audience in designing digital humanities projects, but i also believe it has provided several important lessons for digital humanists seeking to use crowd-sourcing, non-specialist volunteer labor as part of their workflow. it is unlikely that a similar project to early access with a large, paid staff will happen to be funded again anytime soon. still, despite its use of paid employees, my experience as an early access project manager speaks to the need for constant feedback to project participants and methods of quality control for crowd-sourced projects relying on voluntary and free labor. projects such as the library of virginia’s virginia memory do provide a method of limited peer review, but a more robust method of communication between the editorial staff and volunteers, in my experience, is necessary. it is not always helpful to create a one-size list of “do’s and don’ts” for participants, for different volunteers will need more instruction or correction on different points of transcription. we found that constant individual feedback in person, through email, or via our project management software called basecamp was the best way to ensure the best transcription and proofreading results possible. i also believe projects need a reward mechanism to acknowledge their best contributors to keep them engaged and motivated to continue working through to a project’s completion. transcribe bentham, a very successful crowd-sourced project based out of university college london, does a good job of explaining the benefits for participants and has a “hall of fame” where it lists the usernames of everyone who has participated in the project. however, the hall of fame does not distinguish the virginia memory project relies on transcribe, an omeka-based transcription plugin, to allow users to review transcriptions done by their peers. created in part by roy rosenzweig center for history and new media at george mason university and the university of iowa library, for more information on transcribe please see “about the project,” (diy history ). kurtz: founders online users by the number of images transcribed, or by the speed or accuracy of their work. needless to say when your labor force is working for free it is very important that top performers are encouraged and recognized for their exemplary contributions (see “about us” and “hall of fame,” transcribe bentham a and b). we achieved this in early access primarily by giving our employees raises, an option admittedly not applicable to crowd-sourced projects. however, we also found non-monetary ways to reward employees. for example, i rewarded my best employees by assigning them particularly interesting writers and batches of correspondence such as thomas jefferson’s letters with john and abigail adams. i also made a point of acknowledging our best employees’ contributions publicly through basecamp, or praising them during our training meetings. many similar opportunities for rewarding excellent work exist for crowd-sourced projects, whether that is using the principles of gamification as seen on popular language-learning programs like duolingo or the digital crowd sourcing project old weather in which the best users are rewarded for their good work with increasingly high nautical ranks for transcribing weather logs from old ship manifests. highlighting the names of individuals who made significant contributions to the project directly on its website in this way is very important. david rumsey’s listing of his top ten geo-coders on his maps collection site is a perfect example (rumsey ). finally, it is a very good idea to encourage specialization. particular writers’ handwriting or some data sets may be harder to transcribe or record than others. instead of letting anyone edit or transcribe a document as is done on some omeka- based sites, volunteer transcribers should have to demonstrate a proficiency in deciphering the difficult handwriting of such historical figures as abigail adams or james monroe before getting full access to these writers’ letters. not only does this ensure a higher quality of work in the finished product, but we also found that giving access to this important yet difficult subset of letter writers was a useful non-monetary reward that could be copied by others relying on non-expert, volunteer labor. founders online also demonstrates the difficulties inherent in bringing different projects together under one roof that follow different style guides, metadata conventions, and methodology. differences across projects are inevitable confusing kurtz: founders online to users not familiar with the methods of documentary editing. for example, instead of using a single standard convention to indicate that a word or phrase is difficult to read (e.g. surrounding the word with [brackets]), there were several different ways to represent this common editorial issue across different projects. for better or worse, founders online did not attempt to standardize these conventions. similarly, even though the same historical figures appear in different documentary editing projects, the projects have not agreed on a standardized way to spell their names. hence the marquis de lafayette’s long french name appears differently across projects, making a single search for his letters on founders online impossible. while adopting a standard methodology or style guide may prove impossible, the adoption of a names authority lists, perhaps by using the library of congress’s authority files and adding new names as necessary, would help users. another documents compass project titled people of the founding era, a collective biography of the th century u.s., has done considerable work to reconcile different naming conventions across projects, and thus might serve as another potential starting point for standardizing metadata across digital projects focused on early american history. conclusion founders online: early access was a complex, digital project with a large paid staff that was finished at the end of . early access’s successful completion provides a useful model for dealing with the technical issues of large-scale digital humanities work. it shows the need for rewarding hard-working, accurate volunteers while also imposing uniform standards across disparate sets of data. ultimately, founders online’s continued importance will be its emphasis on free access and user friendliness to professional historians as well as the general public. its emphasis on digital methods of access will prove useful to more traditional scholars studying larger topics of interest to the public, while its emphasis on being useful to the public and thinking about the non-scholarly world will help make digital history even more appealing to potential funders. such projects should be encouraged in the future, whether they are similar collections of freely available transcriptions related to a particular topic in american history such as the american civil war, the kurtz: founders online great depression, or the civil rights movement, or large collections of data or other records useful and accessible to researchers, educators, and the general public. competing interests wk was a paid project manager working on

humboldt’s visit to philadelphia and washington, d.c. james f. howell department of german studies, university of arizona, n. oak shadows pl., tucson, az , usa; jfhowell@email.arizona.edu academic editor: bernd fischer received: may ; accepted: june ; published: july abstract: alexander von humboldt was internationally known as a world traveler, having collected data and analyzed samples from five of the world’s seven continents. he spoke several languages fluently, and split most of his adult life between the cosmopolitan centers of berlin and paris. the great deal of time humboldt spent in latin america, along with his staunch belief in human equality, led to his reverence in those countries. indeed, humboldt was a world citizen in the truest sense of the word. but what of the united states? what claim can this nation make to the heritage and legacy of the world-exploring baron? a brief stop in philadelphia and washington, d.c. at the end of humboldt’s expedition to the equatorial regions of the americas seems to suffice. this short stay, along with the humboldt-jefferson correspondence, constitutes the great american link in humboldt studies, a link whose nature and importance has, over the years, received an exaggerated amount of attention from authors writing for an american audience. the following analysis, using the tools of transcultural memory studies, investigates why this relatively insignificant event in a long and storied life assumes an inflated role in current accounts of the life and work of alexander von humboldt. keywords: alexander von humboldt; cultural memory; transcultural memory; thomas jefferson; founding fathers . humboldt’s arrival in the united states on may , alexander von humboldt arrived in philadelphia, marking the beginning of his one and only visit to the united states. between his arrival and departure on june th of the same year, humboldt traveled between philadelphia and washington, d.c., meeting with scientists and dignitaries at every stop. humboldt was the talk of the new republic, indeed the world, after the completion of his five-year scientific and ethnographic survey of south and central america. during his almost six weeks in the united states, humboldt’s inquisitive hosts received him warmly, and he returned the warmth, remarking that the time spent in washington and philadelphia was “the most delightful of [my] life” ([ ], p. ), and that he considered himself from then on to be “half an american” ([ ], p. ix). although humboldt did enjoy his stay in the united states and appreciated the connections he made there, he wrote very little about this pleasant and short detour in his long and storied travels. when later summarizing the final phase of his voyage, humboldt merely remarked that he sailed from havana to bordeaux “by the way of philadelphia” ([ ], p. ). this succinct characterization seems almost unthinkable when compared to recent textual depictions of humboldt published in the united states. with the notable exception of mary louise pratt’s volume imperial eyes: travel writing and transculturation, humboldt and his work have experienced an overwhelmingly positive reception in the united states over the past years. in addition to this general positivity, another hallmark of humanities , , ; doi: . /h www.mdpi.com/journal/humanities http://www.mdpi.com/journal/humanities http://www.mdpi.com http://www.mdpi.com/journal/humanities humanities , , of american humboldt literature is the aforementioned visit to philadelphia and washington, d.c. in the late spring of . recently, writers in the united states have interpreted this short stay not merely as a cornerstone of humboldt’s influence on american culture during the nineteenth century, but also as a defining moment in the prussian baron’s life and intellectual career. although humboldt’s visit and his connection to the founding fathers certainly did not damage his notoriety in the united states during the course of the nineteenth century, it is problematic to overemphasize the relevance of these encounters. indeed, the connections and correspondence humboldt initiated with numerous american scientists and artists in paris and berlin after were more important in terms of his impact on american science and exploration. contrary to the representations in many current accounts, the most probable source of the respect and popularity humboldt enjoyed in the united states came from the translation and publication of the first several volumes of his magnum opus, kosmos. this work was an international sensation, and within the united states its impact was felt and celebrated by the likes of ralph waldo emerson, walt whitman, henry david thoreau, and edgar allan poe. why, then, does this brief and marginally relevant chapter in a life otherwise overflowing with acquaintances and accolades take such a central role in america’s modern understanding and representation of alexander von humboldt? this investigation will demonstrate the ways in which humboldt and his visit to the united states are currently presented to american audiences, as well as analyze the transcultural and mnemonic processes involved in the reintroduction of alexander von humboldt to american cultural memory. . framing humboldt’s visit one need not look far to find the narrative centrality of humboldt’s visit in contemporary american texts. humboldt’s presence on the eastern seaboard and his subsequent relationship with the founding fathers represent the starting point, the turning point, or the conclusion of american accounts of his life and works. aaron sachs, the author of the humboldt current: nineteenth-century exploration and the roots of american environmentalism, begins his work with the following harrowing and adventurous account: “it would have been easier to sail straight back to europe. politics and weather both favored the conservative course: to make the detour from havana to philadelphia, his ship would be forced to brave a british naval blockade and risk a dangerous stretch of water at the beginning of hurricane season” ([ ], p. ). here, humboldt’s visit to the united states serves as the introduction to humboldt and his biography. only later does the reader learn in full detail from sachs about humboldt’s background and accomplishments. the explorer’s scientific influence and contributions to american environmentalism—sach’s central themes—initially assume a secondary role to the establishment of humboldt’s true credentials: his connection to the founders, and thereby to the founding, of the new republic. this association bestows a level of authenticity and indigeneity to the influence humboldt exercised on the imagination and training of early american explorers and scientists. humboldt impacted the american intellectual tradition not only through books and articles as a distant european scholar; rather by highlighting and prioritizing the dangerous passage from havana to philadelphia and the subsequent stay in the united states, humboldt’s story becomes, in part, an american story. laura dassow walls, author of passage to cosmos: alexander von humboldt and the shaping of america, employs humboldt’s visit to philadelphia and washington, d.c. as a turning point in the narrative of humboldt’s biography, as well as in her own investigation. although walls’ account of humboldt’s life does not begin with his time in philadelphia and washington, d.c., these events are afforded special attention and are represented in a way reminiscent of sach’s narrative. as seen in the following selection, walls frames humboldt’s decision to brave the bahama strait in familiarly courageous and daring terms: “beyond the ‘moral obligation’ he felt to see the world’s lone functioning republic, there was every reason to avoid the detour. humboldt was desperate to get himself, his friends, and his collections safely home to paris. [...] heading north risked losing everything they had with them to the british blockades of u.s. ports—assuming his ship was spared by the humanities , , of notorious atlantic storms” ([ ], p. ). this dramatic account of humboldt’s fateful decision to visit the united states initiates the second half of walls' analysis, in which she begins to shift her focus away from humboldt’s biography and onto his influence on nineteenth-century american literary culture. although humboldt’s fame in english-speaking north america would truly blossom with the first translations of kosmos in , walls, among others, claims that the seeds had already been planted in the late spring of . gerard helferich, in his work humboldt’s cosmos: alexander von humboldt and the latin american journey that changed the way we see the world, utilizes humboldt’s brief stopover in the united states to frame the remainder of the explorer’s biographical narrative after having completed his american travels. the twelfth and final chapter of helferich’s book bears the title of “washington, paris, and berlin” [ ]. this condensation of the final two-thirds of humboldt’s life is indeed noteworthy, as it seemingly gives his time spent in washington equal weight to his years spent living and working in paris ( – ) and in berlin ( – ). it should, of course, be noted that the biographical narrative crafted by helferich focuses on humboldt’s experiences in south and central america, and therefore leaves little space for details regarding his life prior to and following the years – . considering, however, the fact that the vast majority of humboldt’s scientific engagement and literary activity took place following his return to europe, helferich’s choice is truly remarkable. it suggests that visiting the united states and encountering thomas jefferson profoundly affected humboldt and his legacy in a way equal to the composition of kosmos, the russian expedition of , or participation in the nineteenth-century scientific discourses centered in paris. these accounts make it clear that visiting the united states was no mere fancy for humboldt on his return journey; indeed, american authors go to great lengths to suggest that some kind of imperative was at work, compelling humboldt to look upon this new republic with his own eyes, and meet the men and women who brought it about. perhaps the most interesting use of humboldt’s visit to frame a biographical narrative is employed by david mccullough in his essay on humboldt entitled “journey to the top of the world.” mccullough, like sachs, begins his account with humboldt’s arrival in the united states in may of ; unlike sachs, however, mccullough does not reveal humboldt’s identity until the reader has been introduced to a well-known cast of american characters. all the reader knows of the “aristocratic young german” on the first page is that he had “come to pay his respects to the president of the new republic, thomas jefferson, a fellow ‘friend of science,’ and to tell him something of his recent journeys through south and central america. for the next several weeks he did little else but talk, while jefferson, on their walks about the white house grounds; or james madison, the secretary of state; or the clever mrs. madison; or albert gallatin, the secretary of the treasury; or those who came to dine in with the president or to do business with him, listened in awe” ([ ], p. ). only after the reader is securely ensconced in the thoroughly american context does mccullough reveal on the second page that “the young man’s name was humboldt, alexander von humboldt—friedrich wilhelm karl heinrich alexander von humboldt—or baron von humboldt, as he was commonly addressed” ([ ], p. ). although not even lasting six weeks, humboldt’s presence in the newly established united states and his subsequent relationship with the founding fathers constitute an axis around which current american historical narratives revolve. . humboldt and the founding fathers recent american accounts associate humboldt’s imperative to visit the united states with his desire to meet and consult with one particular founding father. as joyce appleby succinctly puts it in her volume shores of knowledge: new world discoveries and the scientific imagination: “the purpose of this final leg of their voyage was to meet the president, thomas jefferson [...]” ([ ], p. ). sachs echoes appleby’s assertion in more detail: “if any particular person in the young republic could have quieted humboldt’s wanderlust for a more prolonged period, it would probably have been thomas jefferson himself. president not only of the nation, but also of its foremost philosophical society, jefferson seems to have been the real object of humboldt’s visit to the united states” ([ ], p. ). humanities , , of humboldt had introduced himself to jefferson in a letter, expressing his interest in discussing some of his paleontological finds from the andes with the president. he soon found in jefferson a gracious and intellectually equal host. as david mccullough states: “but there they were in washington for several days, two of the most remarkable men of their time, fellow spirits if ever there were, talking, talking endlessly, intensely, their conversation having quickly ranged far from fossil teeth” ([ ], p. ). the representation of jefferson in many of these texts appears as a personification of the new nation itself, an embodiment of its growth, curiosity, and potential. and in accordance, humboldt’s correspondence with jefferson has come to symbolize in many cases humboldt’s continued interest in and preoccupation with the united states. as helferich explains: “the two men would correspond for many years, and jefferson’s high regard for humboldt is obvious in his letters. [...] the friendship, rooted in their shared political philosophy and common love of science, would endure for more than twenty years, until jefferson’s death in ” ([ ], p. ). as will later be argued, however, this epistolary connection proves to be tenuous at best. jefferson is not the only founding father with ties to humboldt, a fact that is continually underlined in the american investigations of the last years. the best example of this connection between humboldt and the revolutionary generation is provided by walls in passage to cosmos. like mccullough and sachs, walls mentions in detail humboldt’s relationship with james and dolley madison. unlike her counterparts, though, walls goes on to discuss humboldt’s consultations with other, lesser-known founding fathers, such as dr. benjamin rush: “over several visits with the famous physician benjamin rush—the obstinate and passionate reformer who had ridden to the first continental convention with john adams and signed the declaration of independence next to benjamin franklin—humboldt shared his speculations over the moral influence of new world gold and silver” ([ ], p. ). a textual connection emerges among adams, franklin, and the signing of the declaration of independence through rush and his interactions with humboldt. walls again emphasizes this connection to franklin when she notes humboldt’s activities in philadelphia: “the members of the american philosophical society, the premier learned society of the united states (founded by benjamin franklin in ), adopted humboldt as one of their own, voting him to full membership at their next meeting. [...] it was probably in the fine new building of the library company of philadelphia (founded by franklin in ) that humboldt shouted for joy when he read the announcement that his irreplaceable manuscripts had arrived safely home” ([ ], p. ). here the reader is presented with humboldt’s connection to franklin expressed either in his membership in an organization, or in a joyous, yet merely probable, event. some of these connections are tenuous at best, but perhaps the most interesting is the way in which walls creates a textual connection between humboldt and george washington: “one day the party set off for mount vernon, where the visitors drank in the view while [charles wilson] peale mourned for the good old days when he sat and drank with george washington. peale introduced humboldt to billy lee, the last of washington’s slaves, who had been granted freedom and an annuity in his will” ([ ], pp. – ). in this passage, walls not only connects humboldt to the central figure among the founding fathers, she also connects him to the most problematic and divisive element of their legacy. the establishment of such a link to the founding fathers and the complexities of american slavery is remarkable, to be sure, as humboldt was a lifelong abolitionist and an ardent opponent of the slave trade in the americas. . the constitution of convention perhaps the most intriguing elevation of humboldt’s visit to the united states and his relationship with thomas jefferson comes in the form of two recent books written by european authors for american audiences. the first volume, humboldt and jefferson: a transatlantic friendship of the enlightenment by sandra rebok, a european scholar working out of the spanish national research council in madrid, appeared in , and fits neatly into the mold of american humboldt literature. in rebok’s account, the reader again finds humboldt’s imperative to visit the united states: “from cuba they initially intended to return to europe and thus conclude their expedition, but instead they took the spanish humanities , , of ship concepción to philadelphia and added five weeks in the united states to their journey. as we will see, this unplanned visit would assume a special importance in humboldt’s life” ([ ], p. ). the special importance alluded to by rebok takes the form of humboldt’s subsequent friendship and correspondence with jefferson. rebok identifies this relationship as being of extreme importance to both men, as well as being an exemplar of enlightened, transatlantic discourse in a cosmopolitan age. according to rebok, humboldt’s experience in the united states and his connection to its founders was indeed formative: “he had met the founding fathers and architects of the first independent nation on the american continent, and he had seen for himself the functioning of the first republican institutions in the new world. this was the realization of ideals he passionately embraced” ([ ], p. ). although rebok’s text is irreplaceable as perhaps the most detailed and thoroughly researched account of humboldt’s visit to philadelphia and washington, d.c., it contains information that undermines the supposedly strong epistolary connection between humboldt and jefferson celebrated in the title, as well as the overall importance of humboldt’s detour to the united states. rebok notes that humboldt was perhaps one of the most prolific letter writers of his day, penning an estimated fifty thousand letters in his lifetime. jefferson, although not nearly reaching humboldt’s total, still drafted some nineteen thousand letters. the number of extant letters written by the two men to one another, however, totals a mere fourteen: eight letters from humboldt to jefferson, and six letters from jefferson to humboldt ([ ], pp. , ). this sum certainly bespeaks neither a close and enduring friendship nor a passionate connection to an idealized state; rather it seems much more to be a sign of general good will and respectful interest on the part of both men. it is telling, for instance, that many of the succinct letters were written when the two correspondents sent, received, or requested each other’s publications as a gift. even a brief correspondence and the polite exchange of written materials can, to be sure, have a profound impact on a person’s life or an intellectual environment, but there simply is no evidence in the extant textual record to suggest that such was the case between humboldt and jefferson. in the end, rebok’s focus seems to be at times misplaced and her study, although thoroughly researched, faces many of the same interpretational issues experienced by her american counterparts. the second work on humboldt by a european author for an american audience is andrea wulf’s the invention of nature: alexander von humboldt’s new world, published in . in this—the most recent and best-selling work on humboldt to appear in the united states over the last several decades—all of the previously mentioned american humboldt conventions can be found. echoing the suspenseful depictions of the stormy passage from havana to philadelphia crafted by walls and sachs, wulf provides the following riveting account: it was as if the sea were about to swallow them. huge waves rolled on to the deck and down the stairway into the belly of the ship. humboldt’s forty trunks were in constant danger of flooding. they had sailed through a hurricane and for six long days the winds would not stop, pounding the vessel with such force that they could not sleep or even think. the cook lost his pots and pans when the water came gushing in, and was swimming rather than standing in his galley. no food could be cooked and sharks circled the boat. the captain’s cabin, at the ship’s stern, was flooded so high that they had to swim through it, and even the most seasoned sailors were tossed across the deck like ninepins. fearing for their lives, the sailors insisted on more brandy rations, intending, they said, to drown drunk. each wave that rolled towards them seemed like a huge rock face. humboldt thought that he had never been closer to death ([ ], p. ). and all of this so that humboldt could see with his own eyes the new country that supposedly embodied his most heartfelt political and philosophical beliefs, as well as “meet thomas jefferson, the third president of the united states. for five long years, humboldt had seen nature at its best—lush, magnificent and awe-inspiring—and now he wanted to see civilization in all its glory, a society built as a republic on the principles of liberty” ([ ], p. ). wulf also reminds the reader that it is not only jefferson with whom humboldt made a connection while in philadelphia and washington, d.c. madison and gallatin are also featured prominently in the narrative, along with other luminaries of humanities , , of the early republic. most notably, wulf employs a familiar literary tactic, which allows humboldt to forge associations with founding fathers in absentia. in a scene reminiscent of walls’ account, wulf describes how “humboldt travelled to mount vernon, george washington’s estate, some fifteen miles south of the capital. though washington had died four and a half years previously, mount vernon was now a popular tourist destination and humboldt wanted to see the home of the revolutionary hero” ([ ], p. ). another way in which wulf recapitulates american humboldt literary convention is in her representation of the jefferson-humboldt correspondence. in the twelfth chapter of the invention of nature, “revolutions and nature: simón bolívar and humboldt,” wulf presents the correspondence between humboldt and jefferson as a constant back and forth, in which the finer points of the latin american independence movements were discussed in detail. with no further point of reference provided by wulf, the humboldt-jefferson correspondence appears to be the primary source material for the political debates of the age. this implicit characterization is unfortunate, as the latin american struggles for independence were only explicitly thematized in four letters, and often in passing. in wulf’s narrative, however, this was a passionate and important exchange, in which “the former american president, thomas jefferson, bombarded humboldt with questions [...]” ([ ], p. ). in truth, a handful of questions spread out over a small number of short letters hardly constitutes a bombardment. as previously noted, the exchange of each other’s written works was the primary purpose of the humboldt-jefferson correspondence. here again, an otherwise thoroughly researched and responsibly constructed narrative of humboldt’s life and work overemphasizes a relatively minor event and the significance of a handful of encounters. . the transcultural synthesis of memory why is it then that so much recent scholarship and popular writing published in the united states inflates the significance of humboldt’s visit to philadelphia and washington, d.c.? although one might easily make charges of americentrism or intellectual imperialism, processes of cultural memory and cultural integration are actually at work. for example, sachs writes somewhat wistfully that: “it is tempting to wonder what humboldt might have contributed to american politics had he moved to washington and become an advisor to presidents instead of kings” ([ ], p. ). this statement does not advocate the explicit appropriation or annexation of humboldt into american culture; rather it expresses much more a desire to share in humboldt’s cultural and scientific legacy. instead of appropriation, the talk should be of incorporation. this process of incorporation can be at times a bit cumbersome and problematic, as evidenced by the exaggerated accounts in the selections above; but it is also the process by which a culture’s memory adapts and reconfigures itself, so as to include a new element. in the field of cultural memory studies, an element such as alexander von humboldt is best identified as a memory site. this terminology should not be understood as referring to a specific site of historical action; rather memory sites can take any number of forms, including, but not limited to, places, people, events, periods, and ideas. this distinction is essential, as cultural memory studies do not investigate actual past events per se; rather the investigation focuses on how actors in the present create representations and knowledge of the past and to what purpose. although cultural memory “operiert [...] in beiden richtungen: zurück und nach vorne,” and “rekonstruiert nicht nur die vergangenheit, es organisiert auch die erfahrung der gegenwart und zukunft” ([ ], p. ), this is a concept that functions exclusively in the present. in other words, the remembering individual, and thereby the culture to which it belongs, is always present and active, while the event being remembered “is of the past and thus absent” ([ ], p. ). in considering cultural memory as a process of the present, it is important to keep in mind the distinction between history and the past. history is the product of the collection and analysis of textual records of every kind, with the aim of reconstructing a realistic and accurate representation of things that have taken place. the past is also “eine kulturelle schöpfung” ([ ], p. ), but it is not the locus of thoughtful scholarly reflection as history is thought to be; rather the past serves as a necessary, humanities , , of cognitive point of reference and satisfies “das kollektive bedürfnis nach sinnstiftung” ([ ], p. ). the past, unlike the material collections and institutions of history, “ensteht überhaupt erst dadurch, daß man sich auf sie bezieht” ([ ], p. ). in other words, the past, along with the memory sites into which the past is divided, serves as a means of orientation that guides cultural actors in the present. if cultural memory is differentiated thus from history, the age of discovery or charlemagne are as much points of reference as the alamo or auschwitz; and they therefore constitute memory sites “nicht dank ihrer materiellen gegenständlichkeit, sondern wegen ihrer symbolischen funktion. es handelt sich um langlebige, generationen überdauernde kristallisationspunkte kollektiver erinnerung und identität, die in gesellschaftliche, kulturelle und politische Üblichkeiten eingebunden sind und die sich in dem maße verändern, in dem sich die weise ihrer wahrnehmung, aneignung, anwendung und Übertragung verändert” ([ ], p. ). and these sites, much like the cultural memory they constitute, are contextually specific. alexander von humboldt memory sites exist in numerous cultures, but each humboldt memory site interacts with each culture in a specific manner. the german humboldt, for instance differs from the venezuelan humboldt, and each fulfills a different role in the respective cultures. what then are the ways in which cultural memory functions? how is it that some things are remembered and celebrated while others are not? these questions get to the very heart of the representation and use of alexander von humboldt in recent american texts, as they highlight the role of forgetting in the processes of cultural memory. in addition to the aforementioned themes and conventions that pervade contemporary american humboldt literature, humboldt’s absence from twentieth and twenty-first-century american culture forms a cornerstone of almost every humboldt narrative published in the united states. as sachs notes following his depiction of humboldt’s rough passage from the caribbean to the delaware river: “as far as the twenty-first century memory of alexander von humboldt is concerned, he may as well have gone down with his ship: many people have never even heard of him” ([ ], p. ). helferich concurs with sachs, in that “[a]lthough many north americans have a vague sense of humboldt’s name [...] most would be hard pressed to give particulars” ([ ], p. xx). the name might seem familiar to many americans, considering the number of places and natural phenomena that have been named after humboldt; but even this, as appleby concludes, does not protect against cultural amnesia: “what astounds today is how little humboldt is remembered. [...] few great men have had their reputations fade so quickly, just leaving his name on a bay, peak, lake, current, sinkhole, penguin, lily, orchid, and oak whose namesake few remember” ([ ], p. ). this is truly astounding to mccullough, who reflects on the fact that humboldt’s “was a journey that would capture the imagination of the age, but that has been strangely forgotten in our own time. it is doubtful that one educated american in ten today could say who exactly humboldt was or what he did, not even, possibly, in humboldt, iowa, or humboldt, kansas” ([ ], p. ). some authors, such as walls, do not merely lament the level of american ignorance regarding humboldt. indeed, she sees it as a deficiency in america’s understanding of its own history that is in desperate need of correction: “that u.s. american literary and cultural studies have remained oblivious to alexander von humboldt is a scandal exactly equivalent to analyzing romanticism without goethe, naturalism without darwin, modernism in ignorance of einstein, or postmodernism without heisenberg” ([ ], p. x). american authors not only bemoan this absence, it serves as the stated raison d’etre for their work. the reintroduction of humboldt to american culture and the recovery of humboldt’s “environmental thinking” will allow for a host of progressive cultural advances, including “a global debate over capitalism and imperial power” ([ ], p. ). wulf alone slightly breaks with convention and reminds the american reader that not the entire world has forgotten humboldt in the same way: “though today almost forgotten outside of academia—at least in the english-speaking world—alexander von humboldt’s ideas still shape our thinking. and while his books collect dust in libraries, his name lingers everywhere” ([ ], p. ). fittingly enough, these images of dusty libraries and tomes of neglected toponyms allude to aleida assmann’s groundbreaking work on the role of forgetting in the processes of cultural humanities , , of memory. assmann has identified two types of memory that shape a culture’s understanding and representation of itself, and that are constantly engaged in dynamic interaction with one another. there is the active, or functional, memory of a culture, which is comprised of the memory sites being synthesized and utilized by a culture on a constant basis; and the stored, or saved memory of a culture. the functional memory of a culture can be thought of as a kind of canon that is continually invoked by cultural actors as a means of orientation and reference. no memory site in the functional memory of a culture may be assured of continued thematization, however, “[d]enn kanonisierung bedeutet obendrein auch die transhistorische selbstverpflichtung zu wiederholter lektüre und deutung. so bleiben die bestände des funktionsgedächtnisses trotz der bewegung beschleunigter innovation auf den lehrplänen der bildungsinstitutionen, auf den spielplänen der theater, in den sälen der museen, den aufführungen der konzerthallen und programmen der verlage. was einen platz im funktionsgedächtnis einer gesellschaft hat, hat anspruch auf immer neue aufführung, ausstellung, lektüre, deutung, auseinandersetzung” ([ ], p. ). in contrast, the archived memory extant within a culture should be understood much more as “a storehouse for cultural relicts,” in which memories “are not unmediated; they have only lost their immediate addressees; they are de-contextualized and disconnected from their former frames which had authorized them or determined their meaning” ([ ], p. ). the contents of a culture’s stored memory have not lost any of their productive power; rather their creative energy has gone from kinetic to potential. to be sure, there is a constant back and forth between a culture’s stored and functional memory; and this continual deactivation and reactivation “entsteht dadurch, dass die grenze zwischen funktions—und speichergedächtnis nicht hermetisch ist, sondern in beiden richtungen überschritten werden kann. aus dem vom willen und bewusstsein ausgeleuchteten ‘aktiven’ funktionsgedächtnis fallen beständig elemente ins archiv zurück, die an interesse verlieren; aus dem ‘passiven’ speichergedächtnis können neue entdeckungen ins funktionsgedächtnis heraufgeholt werden.” ([ ], p. ). the dynamic relationship between the two forms of cultural memory provides cultural actors with an almost unlimited set of memory sites with which to work. in turn, cultural actors select, activate, and modify these memory sites based on their current needs and aspirations. taking all of this into consideration, the textual representations of humboldt in the united states can be understood as an appeal to the reading public to reincorporate the humboldt memory site into the functional memory of american culture. time and again, these american and european authors decry humboldt’s absence as a loss, and advocate for him and his place in science to be venerated much as they were in the nineteenth century. this advocacy lays bare many of the ways in which cultural memory functions, and provides a fascinating look into the constitution of memory sites in a contemporary context. beyond even this utility, however, the humboldt memory site provides unprecedented insight into the potential of transcultural memory and transcultural influences on cultural memory. this investigation contends that the confluence of humboldt representation in the literary works of american and european authors indicates the initiation of a transcultural memory site. the depictions of humboldt in north america and europe, and more importantly, the cultural motivations and aspirations behind those depictions, have aligned to such an extent that a transcultural space has been created in which multiple cultures can communicate about pressing needs and concerns while drawing on common points of reference. rebok’s humboldt and jefferson and wulf’s the invention of nature demonstrate this transcultural coordination most clearly, as both exemplify the ease with which textual representations of humboldt, and the memory sites they constitute, flow back and forth from european and north american cultural discourses. most certainly, the litmus test of any element within cultural memory is its importance and relevance to the current conditions and needs of a given culture. fittingly, the majority of recent humboldt texts published in the united states and europe present humboldt either as a climate change activist avant-la-lettre, or an embodiment of enlightenment ideals and their potential. by connecting humboldt as securely as possible to the pantheon of the founding fathers and the olympus of the early republic, these contemporary authors elevate his relevance in a way that might affect the humanities , , of reaction of current audiences on both sides of the atlantic to the issues often associated with him, be it global warming or enlightened discourse. the texts investigated here demonstrate an effort, whether conscious or subconscious, coordinated or uncoordinated, toward reincorporating humboldt back into america’s active cultural memory. as andrea wulf states in the epilogue of the invention of nature, “now is the time for us and for the environmental movement to reclaim alexander von humboldt as our hero” ([ ], p. ).

hajnoczky. thomas jefferson university, philadelphia, pa, usa. regulation of mitochondrial motility by milton-like proteins, oip and grif grif and oip are mammalian homologs of milton, a kinesin-binding protein that forms a complex with miro gtpase, an integral outer mitochon- drial membrane ef-hand protein. kinesin, milton and miro have been proposed to function together in the movement of mitochondria along the mi- crotubules. we report here the influence of overexpression of oip and grif on mitochondrial motility and its inhibition by agonist-induced cyto- plasmic [ca þ] ([ca þ]c) signals in h c cells. ha-tagged oip and grif were overexpressed at similar level and were localized to the mito- chondria as detected by immunocytochemistry. in oip and grif overex- pressing cells, elongated mitochondria with varied degree of aggregation were visualized both in live and in fixed, immunostained samples. mitochondrial motility at resting ca þ (< nm) was greatly enhanced by oip and to a lesser extent by grif ( . . and . motility units, respec- tively against a control value of . . motility units). furthermore, the ca þ-dependent inhibition of motility during stimulation by vasopressin ( nm) was suppressed by overexpressed oip ( . . %), whereas grif ( . . %) had no significant effect compared to control ( . . %). overexpression of oip or grif did not alter either basal [ca þ]c or agonist-induced [ca þ]c levels measured by fura . collectively, these data show that both oip and grif can modulate mitochondrial motility presumably, by promoting the association of mitochondria with the motor proteins. furthermore, oip seems to have greater efficacy in the control of mitochondrial movements. -pos board b mitochondrial localization and function relationship

nih, bethesda, md, usa. mitochondrial contribution to cell signaling and function relies on the associ- ation and local communication of mitochondria with the er and the plasma membrane (pm). we have recently shown that the local ca þ communication between er and mitochondria is supported by interorganellar tethers, and cre- ated synthetic linkers that connected the outer mitochondrial membrane (omm) to the er and sensitized mitochondria to er ca þ release. to study the kinetics and short-term effects of the linkage formation, we have now de- vised fluorescent protein pairs targeted to the omm and er or pm containing fkbp or frb domains. rapamycin causes heterodimerization of these pro- teins to form omm-er or omm-pm bridges. confocal imaging of the induc- ible fluorescent linker pairs revealed increased association of er or pm-patches with the mitochondria within minutes of rapamycin exposure. the linkage formation between the er and mitochondria was followed by a decrease in mi- tochondrial motility (> % in min) and by sensitization of mitochondria to ip receptor-mediated ca þ release. linkage formation between pm and mitochondria also suppressed mitochondrial motility. the initial kinetics and spatial distribution of linkage formation could be followed via recording fret between cfp-and yfp-containing linker partners. a longer version of the linker was found to show faster increase of the fret signal, supporting the idea that the rate of linkage formation positively correlates with the tight- ness of the er-mitochondrial contacts. currently, we are using the fret kinet- ics to visualize the areas of close er-mitochondrial interface and study its relevance in the ca þ signal propagation to the mitochondria. thus, inducible interorganellar linkers provide a tool to assess the distance between organelles in live cells, to establish rapid changes in the subcellular distribution and dynamics of the organelles and to evaluate the ensuing changes in organellar and cell function. -pos board b bak/bax-dependent apoptotic signaling in vdac -/- cells soumya sinha roy , william j. craigen , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, baylor college of medicine, houston, tx, usa. bid, a pro-apoptotic bcl- family protein, upon activation forms truncated bid (tbid) that binds to the outer mitochondrial membrane (omm) and engages bak/bax-dependent release of cytochrome c (cyto c) and other intermembrane space proteins from mitochondria to the cytosol to induce apoptosis. the volt- age-dependent anion channel (vdac) is the major permeability pathway for metabolites and ions in the omm but its role in the tbid-induced omm perme- abilization remains controversial. previously we reported that among the vdac isoform-specific knockout mouse embryonic fibroblasts (mefs), only vdac -/- mefs lack tbid induced complete cyto c release and loss of djm. here we show by single cell fluorescence imaging that permeabilized vdac -/- mefs expressing cyto c-gfp were resistant to tbid ( nm)-induced cyto c-gfp release. furthermore, by rescuing vdac -/- mefs with vdac the tbid-induced cyto c-gfp release was restored. in addition, tbid adenovirus infection caused less cell death in intact vdac -/- mefs than in wildtype (wt) mefs. it has been reported that vdac is required for proper targeting of bak in omm. indeed, bak did not appear in the membrane fraction of vdac -/- mefs. along this line we show that permeabilized bak -/- cells were more resistant to tbid induced cyto c release and loss of djm than wt and bax-/- mefs. strikingly, washout of the cytosol further desensitized the bak-/- mefs to tbid. unlike vdac -/- mefs, the bak-/- mefs constitutively overex- pressed bax that was primarily localized in the cytosol. however, recombinant bax ( nm) could induce cyto c release and depolarization in vdac -/- mefs and also supported the tbid-induced cyto c release. thus, in vdac -/- cells bak does not localize to the mitochondria and fails to interact with tbid and does not allow a compensatory increase in bax. the combination of these two mechanisms greatly attenuates tbid-induced omm permeabilization and apoptosis. -pos board b mitochondrial fusion-fission dynamics during hypoxia/reoxygenation xingguo liu, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. structural, biochemical, and functional abnormalities of mitochondria during hypoxia/reoxygenation (h/r) are widely believed to be important pathogenic factors that underlie cell injury. however, mitochondrial fusion-fission dynam- ics responses to h/r are unclear. we investigated the effect of h/r and chem- ical hypoxia evoked by kcn on cellular atp, djm, and on mitochondrial morphology and fusion. sixty min h caused cellular atp decrease to %. djm showed progressive decrease during h, gradually improved in the first minutes r and decreased again during longer r. mitochondrial fusion activity decreased to % during h and to % during r. in addition, anomalous fusion (autofusion and fusion at multiple sites among - mitochon- dria) produced donut-shaped mitochondria during r. cyclosporine a (csa), an inhibitor of the permeability transition pore (ptp) relieved the fusion inhibition ( %) and prevented donut formation during r. five mm and mm kcn could induce cellular atp decrease to % and %, and djm decrease to % and %, respectively. depolarized mitochondria were associated with donut-formation in mm kcn, and with massive swell- ing in mm kcn. fusion activity decreased to % in mm kcn and % in mm kcn, respectively. neither h nor kcn evoked cleavage of opa , the mitochondrial inner membrane fusion protein. thus, both physical and chem- ical h induced respiratory inhibition to gradually lower djm and cellular atp level, and caused fusion inhibition that was not dependent on opa cleav- age. this is sharp contrast of the uncoupler-induced fusion inhibition that has been attributed to the rapid djm dissipation-induced opa cleavage. a conse- quence of ptp opening, the matrix swelling seems to be a key to donut forma- tion since this could be evoked by both mastoparan, a potent ptp activator and by valinomycin, a potassium ionophore. -pos board b governing respiration: tubulin’s c-terminus interaction with vdac kely l. sheldon , dan l.

bethesda, md, usa, joseph fourier university, grenoble cedex , france. mitochondria have long been known to localize within and move along the tu- bulin-microtubule network. it was shown that tubulin binds to isolated mito- chondria with high-affinity and specifically associates with the mitochondrial voltage-dependent anion channel (vdac). we found that nanomolar concen- trations of dimeric tubulin vastly increase vdac sensitivity to voltage allow- ing for vdac blockage at low transmembrane potentials. tubulin interaction with vdac requires the presence of anionic c-terminal tails (ctt) on the in- tact protein. tubulin with proteolytically cleaved ctts does not block the channel. actin, also an acidic protein but lacking ctts, does not induce vdac blockage. two synthetic peptides with the sequences of mammalian a and b brain tubulin ctt do not induce detectable channel closure up to mi- cromolar concentrations. these results suggest a completely new role for regulation of

markets for and beyond in early february, the annual strategies in light conference, covering the techno-busi- ness of solid state lighting, was presented in san mateo by strategies unlimited, (a pennwell publishing subsidiary). this popular meeting, supported by ongoing industry strength, attracted a record attendance of about and a growing array of exhibiting companies that support led application mar- kets. attendees were offered a pleasing sce- nario of interesting papers on industry tech- nology, operating factors and market growth. the growth of high brightness light emit- ter applications categories and their relat- ed markets (hb leds and some lasers) continues to lead the semiconductor arena, with a product strength not seen for quite some time. specifically, only hb leds and non-telecom laser diodes have shown significant growth since .the past average annual growth rates (albeit from small initial values) for almost a decade have approached %, even allow- ing for minimal growth in , and annu- al growth rates of about % are still anticipated for at least the next five years. thus, this industry segment can only be described as very healthy. its market health includes not only the largest direct led application area of cell phone and other hand held lcd back lighting units, followed by the other large growth mar- ket segments, such as out door and indoor signs and auto lighting, but the smaller market segments such as architectural, marine and aviation lighting, road and rail signals and flash units for digital cameras. it has also contributed to record atten- dances at peripheral activities, such as last fall’s led conference and the recent strategies in light meeting. small led, spectacular growth a range of large area, high current and high power led chips are now available from several manufacturers, but the vast majority of the market units is comprised of the original small leds (the and mm packs and the surface mount units). however, according to robert steele, from strategies unlimited, the total value of this small device hb led market showed spectacular growth last year, reaching $ . bn, almost a % growth from . this degree of market growth is quite significant, because there was consider- able price erosion in , with increas- ing unit sales of nitride based devices (more than double those of ). this also accounted for more than % of the market value. the largest market segment in , as noted earlier, was that of back lighting for mobile appli- ances, which now provides about % of the hb led market on a value basis, increasing from % in . in back lighting growth was also supported by a significant increase in cell phones sold and by an increasing conversion to full colour displays. expanding capacity limited for the future, led back lighting is also being considered for the larger ( to inch) lcd displays. blue led key pads (and other colours) are also becoming a large unit market, but most of the hb leds used here are low specification diodes and tend not to be included in the market val- ues. in further support of the strength of this market, all the major players are expanding their capacity, with even more rapid expansion occurring in taiwan, korea and china, thus making non-japan asia the world’s volume supplier. yet the world market is still thought to be capa- city limited. for the future steele forecast growth in most market segments, includ- ing autos, for which the first forward white lighting application (running lights) was announced late in .the main exception to this scenario will be the back lighting market segment, because signifi- cant price competition is expected to erode value growth in the future.the net result of all this hb led growth will be an estimated sales value of almost $ bn in , with the big carrot of general illumi- nation to arrive in or later! how bright can this market get? dr alan mills reporting from san francisco. the thomas

tized to tbid-induced omm permeabilization and cyto c release when com- pared to normal liver. expression levels of vdac and bak were also higher in hcc than in control liver. the role of the vdac -bak pathway in the differential tbid sensitivity was validated by overexpression of vdac in primary hepatocytes. in hcc cells, elevation of bak was also associated with an increased level of mcl- , an inhibitor of bak. furthermore, both constitutive and drug-induced genetic deletion of mcl- in mouse embryonic fibroblasts caused sensitization to tbid-induced omm permeabilization in the absence of a change in bcl-xl or bax . based on these results, we are evaluating the possibility of selective killing of hcc cells by the combination of a bak activator and an mcl- inhibitor. -pos board b which domain of vdac is necessary for bak insertion to the outer mitochondrial membrane and tbid - induced cytochrome c release? shamim naghdi , peter varnai , soumya sinha roy , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadlephia, pa, usa, semmelweis university, budapest, hungary. vdac proteins represent a main component of the outer mitochondrial membrane (omm). the vdac family is composed of isoforms with more than percent similarity. although their primary role was known to be in ion and metabolite transport between mitochondria and cytosol, it has been dis- covered that vdacs are also involved in apoptotic pathways. we have recently found that specifically the vdac isoform is needed for tbid-induced cyto- chrome c release, due to its role in supporting bak insertion to the omm (roy et al. . embo rep. : - ). to determine the domain(s) of vdac which supports bak insertion, vdac and vdac amino acid composition compared and the unique attributes of vdac sequencewereconsideredformutationalanalysis.totestfunctionalsig- nificance of the changes in vdac or vdac , vdac -/- mef cells that are resistant to tbid, were transfected with the mutants and insertion of bak to the omm and cytochrome c release were monitored in permeabilized cells by immunoblotting. previously, we showed that the vdac -specific n terminal tail and cysteins are dispensable for tbid-induced omm permeabilization. to approach the remaining differences four chimeras were prepared: vdac ( - )vdac ( - ), vdac ( - )vdac ( - )vdac ( - ), vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ). these studies revealed that tbid dependent omm permeabilization is only sup- ported by vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ), indicating that the first two third of vdac is required and sufficient for bak targeting to the omm and tbid induced cytochrome c release. -pos board b outer mitochondrial membrane protein distribution and function depend on mitochondrial fusion david weaver , xingguo liu , veronica eisner , peter varnai , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary. cells and tissues deficient in mitochondrial fusion have been shown to have defects linked to the exchange of inner membrane (imm) and matrix compo- nents, particularly mitochondrial dna. outer membrane (omm) constituents originate in the cytoplasm, thus the role of intermitochondrial transfer of omm components by fusion remained unexplored. here we show that fibro- blasts lacking the gtpases responsible for omm fusion, mfn / , have a more heterogeneous distribution of omm proteins than wild-type cells, and in partic- ular that heterogeneity of pro-apoptotic bak leads to dysregulation of bid- dependent apoptotic signaling. homogeneous distribution of bak is partially rescued by introduction of mfn into mfn / -/- cells. furthermore, fusions be- tween mitochondria lacking and containing bak result in hybrids sensitive to bid. proteins with different modes of omm association display varying degrees of heterogeneity in mfn / /- cells and different kinetics of transfer during fusion in fusion-competent cells. efficient coupling of omm to imm fusion depends on the presence of both mfn isoforms and is antagonized by the mitochondrial fission protein, drp . thus, omm function depends on mitochondrial fusion and is a locus of dysfunction in conditions of fusion deficiency. -pos board b mitochondrial fusion dynamics in skeletal muscle of healthy and diseased rat veronica eisner , guy lenaers , gyorgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, inserm u- , institut des neurosciences de montpellier, montpellier, france. mitochondria are highly mobile and dynamic organelles in many cell types. however, in the muscle, mitochondria are crammed into the narrow space among the myofilaments. until now, it remained unclear if mitochondrial fusion occurs in and supports the contractile activity of skeletal muscle (sm). here we applied mitochondria matrix-targeted dsred and photoactiv- able gfp to study mitochondrial fusion in rat fdb sm fibers. in vivo electro- porated fibers were imaged by confocal microscopy. when we tagged the mitochondria in ~ % of cell area with twophoton photoactivation of gfp, rapid spreading of fluorescence showed subsets of interconnected mitochondria, mostly in longitudinal direction. matrix fusion occurred with a rate of . and . events/min in adult fibers and skeletal myotubes, respectively. expres- sion of autosomal dominant optical atrophy-causing mutants of the fusion protein opa or ethanol exposure caused suppression of fusion, which is fol- lowed by mitochondrial dysfunction and late onset myopathies. when chal- lenged by repetitive tetanic stimulation, ethanol exposed cells displayed intracellular ca þ dysregulation, appearing as a fatigue pattern. ethanol also induced a decrease in mfn protein levels, without significantly altering mfn , opa or deltapsi. depletion of mfn alone was sufficient to suppress mi- tochondrial fusion in fdb fibers. fusion inhibition was apparent before any cell dysfunction, suggesting that suppression of fusion is not secondary to other problems in the cells. to directly test the role of mfn in ca þ regulation, ryr -transfected control and mfn ko mefs were stimulated with caffeine. mfn ko cells showed oscillatory ca þ transients that decayed faster than that in the control. thus, fusion dynamically connects skeletal muscle mito- chondria and serves as a target mechanism of both mutations and environmen- tal cues to cause impaired excitation-contraction coupling. -pos board b bcl- proapoptotic proteins distribution in u- mg glioma cells before and

process in the development and maintenance of tissue homeostasis. this process of controlled cell death is tightly regulated by a balance between cell survival and damage signals. we focused our attention towards the intrinsic mitochondrial apoptotic pathway, where bcl- family of proteins plays the major role. we were particularly interested in two pro- apoptotic players bak and bax. here we investigated their role in apoptosis triggered by photodynamic action. we show the localization of bax and bak in u- mg human glioma cells incubated with photosensitizer hypericin (hyp) before and after photodynamic action. apoptotic stimulus by hyp photodynamic action caused bax translocation into mitochondria. however our results suggest that under these condi- tions there are two populations of mito- chondria: one which contains bax and bak simultaneously, and is almost exclu- sively localized near the plasma mem- brane; the other which contains bax only and is distributed throughout the cell. the different protein content and spatial distri- bution of these two populations suggest that they can play different roles in re- sponse to apoptotic stimuli. -pos board b stimulation of bax

cytochrome c release, the commitment step of apoptosis, is regulated at the mitochondria through protein-protein interactions between the bcl- family proteins. an imbalance of this interaction network due to the up-regulation of the proto-oncogenes bcl- and/or bcl-xl lead to a resistance to apoptosis and is associated with tumor formation. bcl-xl overexpression act at the level of the mitochondrial outer membrane (mom) by inhibiting bax-mediated apoptosis; more particularly mac formation and cytochrome c release. how- ever, the molecular mechanisms through which bcl-xl affect earlier steps of bax-mediated apoptosis are not fully understood. surprisingly, we found that mitochondrial bax redistribution and change of conformation were not inhibited but rather spontaneously increased in response of bcl-xl overexpres- sion. in order to further investigate the molecular mechanisms involved in this which domain of vdac is necessary for bak insertion to the outer mitochondrial membrane

proposed the use of nose-cutting to punish women convicted of specific offences, and the use of retaliation (lex talionis) for anyone who deliberately disfigured another person. these punishments were intended to replace the death penalty for these crimes, and as such formed part of jefferson’s attempt to rationalise the virginian law code in line with eight- eenth-century reform principles. jefferson drew on british laws from the anglo- saxon period to the coventry act for his bill, but his proposals contrast strikingly with british movements away from corporal marking as punishment used against their own citizens. this article examines the origins and fates of equivalent crimes and punishments in the law codes jefferson examined, and compares the legal and wider connotations of facial appearance and disfigurement that made these proposals coherent in virginia when they had long ceased elsewhere. tracing examples and discussion of these intersecting cases will greatly increase our understanding of jefferson’s proposals, and the relationships between facial dif- ference, stigma and disability in eighteenth-century america. crynodeb. ym , cynigiodd thomas

the noses of women convicted of certain moral offences, and introducing an eye-for-an-eye system of retaliation (lex talionis) for anyone who disfigured any other person, tends to provoke a strong reaction. even among those who see paradox in the author of the declaration of independence promot- ing equality of humanity while owning slaves, the punishments put forward by jefferson in his proposed overhaul of capital offences in virginian crim- inal law seem strange and anachronistic for a man thought preoccupied with eighteenth-century tastes for civility and legal reform. jefferson’s proposals were the result of impressive research on common and statutory laws, preserved in his ample manuscript annota- tions in modern and old english, latin and french. they never became law: thus, while frequently acknowledged as anomalous to jefferson’s broader humanitarian principles, they have received less attention from jefferson scholars. markus dirk dubber judged the bill a ‘remark- able failure’ in comparison to jefferson’s other reforms, symptomatic of the early republic’s widespread inability to grapple with the philosophy and extent of legitimate punishment, and the relationships between legal persons and authority. maurizio valsania has recently offered fascinat- ing close scrutiny of jefferson’s corporeality and attitudes towards others’ bodies, but omits discussion about these proposals for punitive mutila- tion. yet kathryn preyer argued that the bill, along with jefferson’s pro- posals for religious freedom, property reform and free education, formed ‘part of a single broad and energetic program of reform’, and further scholars have traced the revolutionary effects of many of his proposals. see e.g. merrill d. peterson, thomas jefferson

and even the membrum pro membro of bracton or the punishment of the offending member, altho’ long authorised by our law, for the same offence in a slave, has you know been not long since repealed in conformity with public sentiment. this needs reconsideration. simon a. cole, suspect identities: a history of fingerprinting and criminal identification (cambridge, ma, ), . kathleen m. brown, foul bodies: cleanliness in early america (new haven, );

other jurisdictions like new jersey and pennsylvania extended this punishment to native american and white men, respectively, even if there is no evidence for the latter that the sentence was ever carried out. sodomy virginia, leading the five southern colonies, had adopted the tudor definition and capital punishment for sodomy without enacting its own terri l. snyder, ‘what historians talk about when they talk about suicide: the view from early modern british north america’, history compass,  (), –, at , . bill  online;

john m. murrin cites only one confirmed sodomy trial in colonial virginia. it seems unlikely that women would actually be considered legally capable of sodomy in prac- tice (or similarly, rape), but jefferson does include this possibility both through the specific punishment, and through including a supporting gloss from finch that sodomy denoted ‘carnal copulation against nature, to wit, of man or woman in the same sex’. vi disfigurement as a crime my search of the limited evidence we have for court decisions in virginia has failed to unearth any cases offering significant revision of, or prosecu- tion under, laws against inflicting disfiguring injuries. prior to the revolution, english statutory and common law was therefore the most relevant corpus available. the first reference for any lawyer of the period was of course blackstone’s commentaries. blackstone discusses common law mayhem’s stress on utility, specifically for battle: thus, ‘cutting off [a man’s] ear, or nose, or the like, are not held to be mayhems at common law; because they do not weaken but only disfigure him’. nevertheless, ‘striking out his eye or foretooth’ was classic- ally mayhem, showing the aesthetic component that carried into the common law. in his notes, jefferson quotes further from britton and fleta on the definition of mayhem as injury affecting capacity for battle. meanwhile, early modern statutes offered limited protection from crimes against the person not resulting in death. maliciously louis crompton, ‘homosexuals and the death penalty in colonial america’, journal of homosexuality,  (), –, at . jefferson cites  henry . c. . murrin, ‘“things fearful to name”’, . finch in jefferson, bill  online;

jefferson’s bill explicitly rescinded this equivalence, formalising the need to prove intention for either manslaughter or murder. in another widely cited case, william lee was indicted under the act in  for cutting his sleeping wife agnis’s neck with a razor. here, the prosecution failed because he did not disfigure her face. the act was invoked in the high-profile case of william, earl of devonshire, striking colonel culpeper in the palace of whitehall in , though with quick resolution that the lack of premeditation and significant injury precluded it. the  trial of barny carrol and william king included an exchange with the attending surgeon about whether cranley thomas kirby’s nose was ‘slit’ (as per the act), or ‘divided’, ‘incised’, ‘cut’, ‘wounded’, etc, which was a recurring course of defence (e.g by coke/ cooke). they were found guilty, as was thomas hand for wounding joseph holloway in the arm with a pistol in . in contrast, samuel dale failed to have thomas brooks’s assault on him upgraded to a felony after he lost the sight in his eye, because unable to prove that brooks had lain in wait with intent. the actions required to satisfy ‘lying in wait’ in britain were substan- tially expanded by a ruling from justice sir james eyre in the trial of thomas mills in april , which held it sufficient ‘for a man who has a purpose in his mind to do such kind of mischief, and deliberately watches an opportunity to do it’. it would have little effect, however, as the  revision of the legislation removed the requirement entirely: ralph heathcote, the irenarch: or, justice of the peace’s manual, , rd edn (), –. his remarks on the case were reprinted in sylva;

on the other hand, it removed these requirements for any who ‘shall voluntarily, mali- ciously and of purpose, pull or put out an eye while fighting or otherwise’, giving theoretically greater protection against the local eye-gouging brawls, rather than the traditionally symbolic nose. if guilty, the offender and his or her ‘aiders, abettors and counsellors’ would be jailed for two to ten years, and fined up to $,, ‘three fourths whereof shall be for the use of the party grieved’. such compensation rules also removed any need for a separate civil suit by the victim. this act was revised again in . in addition to returning hanging to high treason, it was the first to explicitly exclude slaves as defendants from its provisions. a notable case of  held that it could neverthe- less protect slaves themselves from malicious disfiguring violence. the revision again rescinded the ‘lying in wait’ requirement, and created a new two-part offence wherein the key difference was the weapon used: biting, or stabbing or shooting. in each case, the penalty remained the same as in the  act. the case of john somerville, charged with maiming john g. jackson in  (he was ultimately found guilty of mis- demeanour assault), still retains reference to ‘lying in wait’, suggesting it remained an informally aggravating factor even outside of the active statute. nevertheless, henry st george tucker focused on mayhem as permanent injury that ‘disabled’ the individual from fighting, and  ibid., ii, , . preyer, ‘crime’, . shepherd, statutes at large, ii, .  ibid., . preyer, ‘crime’, . shepherd, statutes at large, ii, –. commonwealth v dolly chapple. the defence argued that as a slave could not own property s/he could not receive the stipulated damages. the prosecution successfully coun- tered that such logic would exclude femes covert from protection, which would be ‘monstrous’: william brockenbrough and hugh holmes, a collection of cases decided by the general court of virginia [–] (philadelphia, ), –. shepherd, statutes at large, ii, . commonwealth v john somerville, in brockenbrough and holmes, collection of cases, –.        cambridge core terms of use, available at https://www.cambridge.org/core/terms. https://doi.org/ . /s downloaded from https://www.cambridge.org/core. carnegie mellon university, on apr at : : , subject to the https://www.cambridge.org/core/terms https://doi.org/ . /s https://www.cambridge.org/core the capacity for the court to increase damages if it thought the jury had been too lenient. while obviously a reduction from the death penalty, jefferson’s sug- gestion that an assailant should be disfigured ‘in like manner’ was extra- ordinary. in the bill he cites fleta, britton (which prescribed loss of the equivalent member for men, but loss of the offending hand for women) and the law of king alfred (ll. Ælfr. . ), rather than bracton on membrum pro membro as he referenced in his letter to wythe. he omits blackstone, who considered the action arcane and inadequate; however, he may have been influenced by blackstone’s opinion that one of its drawbacks was inability of repetition, in providing for retaliation against a part judged equivalent. there are precedents for this equivalency in english law. among the provisions for aggravated cases of affray, for example, anyone convicted for striking another with a weapon (or drawing with intent to do so) in a church or churchyard would be excommunicated, and ‘have one of his ears cut off; or, having no ears, be branded with the letter f in his cheek’. it seems unusual for jefferson to leave such an open field for the judging of this equivalency, given his professed intention to remove wiggle room in courts, but this too carries antecedents in the medieval wergeld that awarded damages for injury based on intricate valuations of body parts. vii disfigurement as a punishment the use of disfiguring punishments was by no means unknown in either europe or america, even if jefferson was a lone voice for the lex talionis. branding the hand for benefit of clergy remained a key form of both judi- cial discretion and physical marking employed by british and american courts, and arthur scott demonstrated its frequent use in pre-revolution- ary virginia. acts like coventry had to specifically preclude benefit of clergy for felonies. until  women could not claim benefit of clergy, and thereafter only for petty thefts;

punishments had precedent in the treatment of slaves. from testimonies, runaway advertisements and other sources, we see slaves marked in a wide variety of ways. ear-crop- ping is a recurring one, as is the branding of the master’s initials or the letter ‘r’ for ‘runaway’ on the face and/or body. a virginia law of  stipulated that a slave convicted of hog-stealing once would be whipped, and twice would have both ears torn at the pillory. the sen- tence was extended to any free person in . the threat was also thought a good equivalent to swearing on the bible in capital trials of slaves: ‘negros, mulattos, or indians, not being christians’ required to testify were to be informed that if they gave false evidence they would lose both ears at the pillory and be whipped. formal and informal disfigurements are found throughout british and american slaveholding regions, and were emphasised by anti-slavery writers keen to reveal how ‘american taskmasters … notch the ears of men and women, cut pleasant posies in the shrinking flesh, learn to write with pens of red-hot iron on the human face.’ lewis clark, an escaped slave from kentucky testifying to abolitionists in , also highlighted that disfigurement outside statute was hardly unexpected: ‘the law [of kentucky] don’t allow ’em to brand a slave, or cut off his ear; but if they happen to switch it off with a cow hide, nobody says anything about it.’ early laws based on english vagrancy punishments had marked runaway servants: in  a second- offender’s cheek was branded with ‘r’, before this moved to the shoulder in , and the hair close-cropped for all offenders. but restrictions on flogging as an increasingly racialised punishment in british colonies, see, e.g., amanda nettelbeck,

or dismembered (such as losing toes). into the nineteenth century, slaves faced capital charges for disfiguring white people in cases where white perpetrators would face only fines, pillory or imprisonment. as kirsten fisher notes, the continuation of such practices in the face of increased restraint against white bodies was one way in which racial difference was ingrained. but despite a significant imbalance in the acceptance, range and fre- quency of such punishments, corporal punishment including disfigure- ment was also used on free individuals well into the nineteenth century. alongside execution, which might be followed by dissection or hanging in chains, public whipping and other forms of judicial muti- lation ensured that the body was deeply integrated into ‘a public economy of punishment’. ear-cropping is the most frequent disfigure- ment meted out as a punishment in colonial america, including virginia, and carried british precedents. in , the ship captain robert cornish (alias williams) was executed in virginia for forcibly sodomising one of the ship’s boys, william couse. a number of men linked to the case criticised the execution (on unknown grounds), two of whom were punished by the loss of an ear and either one year of indentured servitude or whipping. north carolina included ear-cropping among its penal- ties for perjury: those guilty were fined, ineligible to give further testi- mony in any court, and pilloried for an hour before their ears were cut off and nailed to the pillory until sunset. new england was the most enthusiastic in its use of branding and other marks, but even pennsylvania – which virginia would shortly look to after the success of its new penitentiary – only removed remaining branding, ear crop- ping, etc., in . the army employed branding well into the nine- teenth century after it had left other (white) judicial punishments, see, for example, the case of abram in alabama , who successfully appealed a capital conviction for biting off a section of an overseer’s ear because () part of the ear was not mayhem, and () his life was in danger: in lawrence friedman,

surgeon in the union army, wrote a traumatised account of being tasked with branding an irish deserter in . marking the bodies of criminals was one way in which criminal identity could, in theory, be fixed, but this was never certain: cases of innocent disfigurement resembling the legal practices were recorded in kentucky courts, so that the individual could be defended against misreadings. in a rare gap, jefferson offers no citations for cutting women’s noses. his letter to pendleton shows an early intention to use castration to punish ‘rape, buggery, &c.’ but makes no mention of nose-cutting, or the use of retaliation for disfigurement. there is a long global tradition of inflicting nasal wounds upon sexual transgressors, with cases stretching from antiquity to the present, across egypt, europe and the middle east, through southeast asia and the pacific islands. punitive rhinotomy was practised by the blackfeet in the late nineteenth century, although it is not known how widely or for how long this might have existed in america. it was the status of injuries to the nose as inhonesta vulnera – dishonouring wounds – that was in part responsible for the emphatic punishment prescribed by coventry and related legislation. while male and female noses were protected by his disfigurement law, the dis- tinction between castration and nose-boring for the other offences shows his gendering of official judicial actions against this part of the body. as with the hebraic ‘eye for eye’, there was biblical precedent for rhi- notomy as a punishment for female sexual transgression (ezekiel :). slitting the nose of adulterous or otherwise sexually transgressive women was a widely known threat in early modern britain. while king edgar had used nose-cutting for some thefts, it was cnut (r. –) and archbishop wulfstan of york (fl. –) who introduced nasal mutila- tion – along with loss of the ears – for women convicted of adultery. jefferson does not refer to cnut here, but does elsewhere. his omission robert fantina, desertion and the american soldier, – (new york, ), ; simon winchester, the

been intended to suggest restraint, but it also more closely echoes established laws in neighbouring jurisdictions, especially boring the tongue in new england. a final clue appears in jefferson’s legal commonplace book. here, he closely paraphrases a comment from henry home, lord kames’s history of the criminal law that according to diodorus siculus, in ancient egypt, ‘he who committed a rape was castrated. a woman committing adultery, lost her nose, that she might not again allure men to wantonness.’ kames holds this an example of egypt’s ‘perfection’ of the criminal law, since ‘revenge is thereby kept within the strictest bounds, and confined to its proper objects’. diodorus may have overstated the neat equivalency in this case, since adultery was more commonly met with death, but castration and rhinotomy were certainly used elsewhere. while a different crime, the note shows the alignment of rhinotomy with female sexual transgres- sion, their ‘allure’ to men, and the equivalency with male castration, which evidently had some appeal to jefferson. viii conclusion in notes on the state of virginia, jefferson presented his revised criminal code in an elegant table, arranged according to punishment: life, limb, and labour. the provisions under question are set out as follows: ii. crimes whose punishment goes to limb. . rape, ) dismemberment. . sodomy,

there is an element of obfuscation in placing castration behind the broader category of ‘dismemberment’. moreover, these laws had not passed when jefferson published the book. the summary echoes jefferson’s two ostentatiously careful manuscripts of bill , the notes arranged in columns to mirror legal heroes like coke. these carefully elu- cidatetheprecedents upon which jefferson wasrelying toput forward acode he desired to be marked by ‘accuracy, brevity and simplicity’. where dumas malone had seen the extensive notes as evidence of jefferson’s inter- est in the topic, julian boyd saw the annotations as jefferson’s ‘pedantic ostentation’, and dubber an excuse to ‘practice his penmanship’. considering the annotations and research alongside the problematic history of the coventry act in practice, however, illuminates why the keen lawyer struggled to find an adequate means of revising the provi- sions against disfigurement – one that even he grew to dislike. when beccaria’s appeal against capital punishment gained traction among reformers, those still in favour of the punishment were compelled to defend it with unprecedented vigour: vic gatrell notes that ‘elaborate pleading’ was newly necessary, ‘because older certainties had become uneasy’. jefferson’s exhausting annotations of the corporal punish- ments hint at similar strain to justify punishments that might seem ‘revolting’. virginia’s simplifying of the coventry act’s requirements of intention and circumstance, for all they fluctuated in different revisions, represented attempts to combat the real problems that the act had faced in practice in britain, and criticisms of its application. replacing the death penalty for this and the other offences with proportional punish- ments was supposed to increase efficacy, justice and rationality in post- revolutionary virginian law. i am inclined to agree with peterson that jefferson was in a sense ‘trapped by a misplaced desire for simplicity’, in striving for a code so straightforward, proportional and logical that mercy could never be at ‘the eccentric impulses of whimsical capricious designing men’. neither an out-of-the blue aberration, nor an over- looked hangover from earlier law, jefferson’s lex talionis approach to facial disfigurement as both a crime and a punishment drew on prece- dents from medieval england and closer to home, and reflected the anxious balance of punishment of body and mind at work in eight- eenth-century legal reforms. julian boyd, lyman h. butterfield and mina r. bryan

vaccaro md, phd published online: february � the association of bone and joint surgeons spine surgery, like other methods of invasive intervention, has specific common, and not so common, complications that may occur in the normal course of treatment. any physician so treating a problem must be cognizant of the anticipated course subsequent to his or her management to understand when recovery fails to proceed normally. such an acute awareness of treatment adverse events or com- plications will allow institution of appropriate remedial measures necessary for the best patient care and ultimately outcomes. as surgeons, we believe it is important to acknowledge and study our failures. this symposium reports original research on the potential complications of spine surgery to inform the orthopaedic and neurosurgical communities about possible best practices. the articles in this symposium encompass the spectrum of complications from diagnosis to surgical technique to postoperative healing. complication rate and common complications are explored in basic science and clinical research settings. we believe study of complications is essential to improving the ultimate outcome of spine care. we hope readers enjoy this symposium. fig. dr. radcliff is shown. fig. dr. vaccaro is shown. all icmje conflict of interest forms for authors and clinical orthopaedics and

novel, calcium-independent, pkca-dependent signaling pathway, which results in mitochondrial depolarization. as a result, mitochondrial dys- function is likely to be a key contributor to the pathophysiology of gas embo- lism injury. further, this connection between the endothelial surface layer and endothelial mitochondria may also play an important role in vascular homeo- stasis and disease. -plat calcium-induced ros generation during ischemia triggers mptp- dependent cell death during reperfusion lea k. seidlmayer, vanessa v. juettner, lothar a. blatter, elena n. dedkova. rush university medical center, chicago, il, usa. impairment of mitochondrial function is a central event of ischemia- reperfusion (i/r) injury leading to tissue damage and cell death. we studied the relationship between mitochondrial ca þ overload, reactive oxygen species (ros) generation, opening of the mitochondrial permeability transition pore (mptp) and cell death in rabbit ventricular myocytes exposed to simulated i/r. changes in mitochondrial ca þ ([ca þ]m) were measured with x-rhod- , ros generation with mito-sox red, mptp opening as mitochondrial calcein red release, and cell death as lactate dehydrogenase release. i/r was induced by exposing cells to glucose-free tyrode solution containing mm -deoxyglu- cose and mm nacn, ph . , followed by superfusion with standard tyrode solution. no cell death was observed after min of ischemia despite a signif- icant increase in [ca þ]m, ros and mptp opening, however cell death in- creased significantly after min of reperfusion. the ca þ uniporter blocker ru partially prevented [ca þ ]m increase and completely abolished ros generation and cell death when applied during i/r, however application of ru only during reperfusion did not protect from cell death. scavenging ros with superoxide dismutase mimetic mntbap or antioxidant trolox pre- vented reperfusion-induced cell death. blocking mptp during ischemia by cyclosporine a or depletion of mitochondrial inorganic polyphosphate did not provide protection against cell death during reperfusion, but instead led to increased mitochondrial ros accumulation. however, inhibiting mptp opening during reperfusion with cyclosporine a attenuated cell death. we con- clude that mptp-dependent cell death during reperfusion is mediated by ca þ- dependent ros generation during ischemia. moreover, our data suggest that mptp opening during ischemia could serve as ros escape pathway from mitochondria and thereby attenuate mitochondrial ros accumulation and ros-mediated cell damage during subsequent reperfusion. -plat dynamic measurement of ca d -induced changes in organelle-specific redox microdomains david m. booth , balázs enyedi , miklós geiszt , péter várnai , györgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary. multiple interactions between ca þ -signalling and reactive oxygen species (ros) production are thought to exist and be of both physiological and patho- physiological relevance. however, until recently, the study of ros in the con- text of ca þ-signalling has been hampered by ros probes limited in both specificity and targeting. to measure ros in discrete subcellular domains, we compared the genetically-encoded ratiometric h o sensor hyper with the redox de-sensitized derivative sypher to control for non-specific changes. these probes, targeted to the er lumen, er membrane (cytosolic face), cyto- sol, mitochondrial matrix and outer membrane (omm) and the ip -receptor, are positioned to assess redox changes at a local level. in resting conditions, the er lumen showed > -fold increased hyper ratio compared to the outside of the er membrane, bulk cytosol and mitochondrial matrix and omm. in the er lumen, ip -linked ca þ -mobilization induced a prounounced, downward shift in hyper ratio, whereas little or no change was detected in other compart- ments. in permeabilized cells, mitochondrial ca þ-overload was accompanied by substantial increase in h o detected in the matrix and at the omm. these data demonstrate that redox environments within individual cellular compart- ments constitute a complex and dynamic interrelationship with the concentra- tion of free ca þ . the er lumen is highly oxidized and exhibits profound decreases in h o concommitant with ca þ -release. interestingly, these changes are not transmitted to the outer leaflet of the er membrane or to other compartments. mitochondria resist redox changes under moderate stimulation, however, during mitochondrial ca þ-overload and collapsed membrane poten- tial, strong h o generation is detectible in the matrix and at the mitochondrial surface. the ros generated and detected at locations immediately apposed to ca þ -transport proteins, such as the ip -receptor, may modify their function at a local level and contribute to the feed-forward cycle of ca þ -dysregulation and subsequent cell death. -plat er-mitochondrial ultrastructure in the liver of normal and ethnaol-fed rats gyorgy csordas , david mankus , antony anil noronha , jan hoek , carmen mannella , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, wadsworth center, albany, ny, usa. chronic alcohol consumption causes severe pathology in liver, associated with altered metabolism and reduced atp production. liver mitochondria isolated from alcohol-fed animals show decreased capacity for electron transport and atp synthesis, impaired calcium handling, and increased ros. in parallel, the endoplasmic reticulum (er) also shows increased ros and a stress re- sponse. the close correlation between defects in mitochondria and er is matched by recent evidence of the functional integration of cellular responses (including calcium signaling) involving these organelles. to evaluate the ultra- structural basis of alcohol-induced changes, we performed transmission elec- tron microscopy and electron tomography studies of rat liver. hepatocytes showed a large number of mostly round mitochondrial cross sections, which oc- cupied ~ % of the cytoplasmic area. the cell cytoplasm in chronic ethanol- fed ( months) condition exhibited reduced particle density, indicative of cell swelling, and contained large lipid vesicles. the mitochondria were generally intact but showed narrower intermembrane spacings within cristae and at the organelle periphery, consistent with low-scale matrix swelling. in both control and ethanol-fed conditions, mitochondria were typically surrounded by exten- sive er, with cisternae sometimes sandwiched between neighboring mitochon- dria. in one case, er was prominent at a site of mitochondrial fusion/fission. as previously reported, regions of close er-mitochondrial association ( - nm) contained numerous ‘‘tethers’’ between outer mitochondrial membranes (omm) and adjacent er. while individual tethers were discernible, dense granular material (including ribosomes) within omm-er interfaces interfered with accurate quantitation of tethers. however, membrane spacings could be readily measured. it was found that the mitochondrial surface in close associ- ation with er was significantly reduced in the chronic ethanol-fed condition as compared to control ( . % vs. %). this might be expected to cause reduced calcium signaling between er and mitochondria in liver after chronic alcohol ingestion. -plat mitochondrial nm -h /ndpk-d is multifunctional: intermembrane cardiolipin transfer linked to apoptosis uwe schlattner ,

in the mitochondrial intermembrane space. the well established function of the en- zyme is phosphotransfer activity as a nucleoside diphosphate kinase (ndpk), using mitochondrial atp to regenerate nucleoside triphosphates. nm -h is further known to strongly bind in vitro to anionic phospholipids, mainly cardi- olipin, and in vivo to inner mitochondrial membranes. we show here that such protein/lipid complexes inhibit ndpk activity but are necessary for nm -h to function in selective intermembrane lipid transfer. nm -h -deficient hela cells expressing either wild-type nm -h or a membrane-binding deficient mutant were analyzed by membrane fractionation and lc-esi-ms. data revealed that wild-type nm -h increased cardiolipin content in the outer mitochondrial membrane as compared to mutant enzyme. this correlated with higher susceptibility of wild-type enzyme expressing cells to rotenone-induced apoptosis as seen by increased annexin v binding, elevated caspase / activity and stimulated release of cytochrome c into the cytosol. molecular modeling of nm -h binding with cardiolipin reveals potential intermembrane transfer mechanisms. we propose that nm -h acts as a lipid-dependent mitochondrial switch with dual function, allowing either for phosphotransfer or for cardiolipin transfer, with a role in apoptotic signaling. calcium-induced ros generation during

bronchial isomerism krishna k mohan, neil kramer, mitchell l margolis, robert m steiner, herbert e cohn from the division ofpulmonary diseases and departments ofmedicine, radiology, and thoracic surgery, thomas jefferson university hospital, philadelphia, pennsylvania pulmonary sequestration is an uncommon congenital anomaly characterised by a mass of non-functional, dysplastic lung parenchyma that docs not communicate with the normal tracheobronchial tree. such an anomaly commonly receives its blood supply from the systemic circulation. the sequestered pulmonary segment is considered to be intralobar if it is enclosed within the common pleura enveloping the normal lung and extralobar if it has its own separate pleural investment. intralobar pulmonary sequestration is only rarely associated with other congenital anomalies, whereas a large proportion ofcases of extralobar sequestration are associated with diaphragmatic hernias and other congenital anomalies. ' this case report describes a patient with an intralobar sequestration on the right side who also had a left-sided bronchial anatomy on the right (bronchial isomerism). to our knowledge this association has not been previously reported. case report a -year-old white woman who worked as an insurance executive was admitted to thomas jefferson university hospital because of recurring haemoptysis. blood-streaked sputum had been noticed by the patient over several years. there were no other symptoms referable to the respiratory system or cardiovascular system. she did not smoke cigarettes. physical examination showed nothing abnormal. the initial chest radiograph showed a well-demarcated, round soft-tissue density in the region of the medial basal segment of the right lower lobe, and the pulmonary vessels to the right lower lobe appeared abnormal. flexible fibreoptic bronchoscopy showed no bleeding sites or endobronchial lesions up to the fourth-generation bronchi. the bronchial anatomy on the right side, however, was a mirror image of that on the left. a relatively long right main-stem bronchus led to upper-lobe and lower-lobe bronchi; the upper-lobe bronchus led to a middle-lobe and a true upper-lobe bronchus. each of the lobar bronchi had two segmental divisions-an isomerism of the left-sided anatomy with upper-lobe and lingular counterparts. inspection of the right lower lobe showed hypoplasia of the lobar bronchus with regional inflammation. one apical and two of the four basal segmental bronchi could be identified, address for reprint requests: dr kk mohan, division of pulmonary disease, thomas jefferson university hospital, philadelphia, pa , usa. but these appeared to be rotated and displaced. selective bronchography on the right side confirmed left-sided pulmonary isomerism (fig la and lb). an abdominal aortogram showed that an aberrant artery arising from the abdominal aorta, cephalad to the coeliac axis, supplied the sequestered lung mass. the aberrant artery had a large aneurysmal dilatation in its course (fig ). the venous return from the sequestered lung segment was through a cluster of veins into the hepatic vein via a defect in the diaphragm. a clinical diagnosis of pulmonary sequestration with pulmonary bronchial isomerism was made. exploratory thoracotomy showed a bilobed right lung, the upper lobe providing a lingula counterpart. an intralobar sequestra- tion was located in the medial portion of the right lower lobe with its aberrant systemic arterial supply arising from below the diaphragm. the sequestrated lung segment was removed with its aneurysmal feeding vessel. the patient tolerated the procedure well and made a satisfactory recovery. discussion intralobar pulmonary sequestrations constitute - - % of all congenital pulmonary malformations. in a review of cases of intralobar pulmonary sequestration savic et al noted a concomitant congenital anomaly in only - % of the cases. in no case was bronchial isomerism identified, nor do other reports of pulmonary sequestration" mention coexisting bronchial isomerism. four types of bronchial isomerism have been described. so far none of these has been reported to be associated with pulmonary sequestration. type i, which predominates in males, consists of bilateral trilobed lungs and is associated with asplenia, malrotation of the gut, and congenital cardiovascular anomalies that include transposition of the great vessels, atrial septal defects, ventricular septal defects, and right-sided aortic arches. type ii bronchial isomerism consists of anisosplenia associated with the other features of type i isomerism. type iii combines bilateral bilobed lungs with polysplenia, gut malrotation, and congenital heart disease, and appears to have no sex predilection. type iv bronchial isomerism syndrome occurs most often in females and includes bilobed lobes with gut malrotation, anisosplenia, and a double outlet from the right ventricle. our patient decinedi to thave\ a liver or spleen scan but the aortographic study did show a normal splenic artery and left gastric arteries arising from the coeliac axis. bronchial isomerism almost never causes symptoms. o n a p ril , b y g u e st. p ro te cte d b y co p yrig h t. h ttp ://th o ra x.b m j.co m / t h o ra x: first p u b lish e d a s . /th x. . . o n ja n u a ry .

infections in the sequestered lung segment. in either case early resection of the sequestration is the preferred treatment. the developmental origins of these uncommon congenital anomalies are of interest to embryologists, bronchoscopists, and surgeons. intralobar pulmonary sequestrations develop from accessory lung buds, which are enveloped by the normal lung and pleura during their caudal migration. on the other hand, bronchial isomerism as a phenomenon is more difficult to explain-presumably the bronchial pouch, budding off the laryngotracheal cleft before the th week of intrauterine life, fails to subdivide normally. clinicians must be aware of the multiple associated congenital anomalies of the lung, gut, abdominal viscera, heart, and blood vessels so that they can diagnose and treat any associated illnesses. references savic b, birtel fj, tholen w, funke hd, knoche r. lung sequestrations: report of seven cases and review of published cases. thorax ; : - . weekly

studies on the epstein–barr virus (ebv), an important human tumor virus. ebv causes lymphoma development in immunocompromised individuals and is also linked to several major human cancers including nasopharyngeal carcinoma and hodg- kin’s lymphoma. several of the cancers linked to ebv occur with endemic patterns of incidence, suggesting that environmental or genetic factors also contribute to the development of these tumors. her earlier work analysed variation in the viral genome in tumors from various regions and also characterized ebv expression in the various malignan- cies associated with ebv. these studies contributed to the identification of the viral proteins that have potent effects on cell growth and regulation. she has shown that the viral protein lmp activates nfkb in epithelial and lymphoid cells, and in epithelial cells specifically activates expression of the epidermal growth factor. recent studies of the viral protein lmp have shown that it activates the akt kinase and wnt signaling. she is presently developing model systems to identify synergy between the effects of expression of viral proteins in specific cell types and cellular genetic changes. she is

of neuronal ca + sensor- during stress wednesday, february , a like ursodeoxycholic acid (udca) and tauroursodeoxycholic acid (tudca), are cytoprotective and inhibit cell death. the mechanisms associated with these distinct effects are not entirely clear. however, the effect of hydrophilic bile acids seems to be related with the blockage of a series of processes that converge on mitochondrial damage. bax is a pro-apoptotic protein that belongs to the superfamily of the bcl- proteins and is involved in mitochondrial pore formation. submicellar concentrations of cytoprotective bile acids have been shown to modulate bax concentration in mitochondria, suggesting that these molecules may interact directly with the protein. in this study, our objective was to evaluate the affinity of bile acids to recombinant bax protein, making use of fluorescence spectroscopy (fret and fluorescence anisotropy), as well as fluorescence correlation spectroscopy (fcs). our results show that the cytoprotective bile acids udca and tudca associate with recombinant bax protein with high affinity, while the cytotoxic bile acid dca only seems to be able to adsorb to the protein with much lower affinity. notably, the bind- ing site for udca seems to be located in a hydrophobic pocket of the protein. this interaction could be responsible for the disruption of bax translocation to the mitochondrial outer membrane in the presence of udca and/or tudca. supported from fct/portugal (projects ptdc/qui-biq/ / and reci/ctm-pol/ / ). t.s. and f.f. acknowledges fct grants sfrh/bd/ / and

di-bromocarbazole derivatives with anti-apoptotic function have been developed and tested in several mouse models of brain injury and neurodegeneration [ - ]. owing to the increased therapeutic potential of anti-apoptotic di-bromocarbazole de- rivatives, we sought to expand our knowledge of the mechanism of action of these small molecule inhibitors. we investigated the kinetics of mac inhibi- tion in mitochondria from wild type, bak, and bax knockout cell lines using patch clamp electrophysiology, fluorescence microscopy, elisa, and quantita- tive western blot analyses. our results show that imacs work through at least two mechanisms: ) by blocking relocation of the cytoplasmic bax protein to mitochondria and ) by disassembling bax oligomers in the outer membrane. a comparison of the inhibitory effects over channel conductance and cyto- chrome c release suggests that the imacs interacted with both bax and bak with similar kinetics. interestingly, wild type mitochondria were more suscep- tible to inhibition than the bak or bax knockouts. a quantitative western blot analysis showed that wild type mitochondria had lower steady state levels of bak, which suggests an uneven stoichiometry of the mac components. -pos board b tyrosine phosphorylation of mitochondrial ca d uniporter regulates mitochondrial ca d uptake jin o-uchi, stephen hurst, jyotsna mishra, xiaole xu, bong sook jhun, shey-shing sheu. depariment of medicine, center for translational medicine, jefferson medical college, thomas jefferson university, philadelphia, pa, usa. mitochondrial ca þ has a critical role for balancing cell survival and death. ca þ influx into mitochondrial matrix is mediated primarily by the mitochondrial cal- cium uniporter (mcu). however, the signaling pathways that regulate mcu channel functions via post-translational modifications of mcu are completely unknown. here we show that adrenergic signaling induces mcu tyrosine phos- phorylation and accelerates mitochondrial ca þ uptake in cardiac cells. adren- ergic signaling induces activation of proline-rich tyrosine kinase (pyk ) and translocation into the mitochondrial matrix; enhancing the interaction between pyk and mcu, which subsequently accelerates mitochondrial ca þ uptake via pyk -dependent mcu tyrosine phosphorylation. mcu contains tyrosine res- idues ( in the n-terminus, in the pore-forming region, in transmembrane do- mains and in the c-terminus), which are conserved across all eukaryotic species. among them, only of these tyrosine residues (y at n-terminus, y , and y at c-terminus in mouse mcu) remained as potential phosphor- ylation candidate sites for protein tyrosine kinases using phosphorylation predic- tion programs. we mutated these tyrosine residues to phenylalanine and generated non-phosphorylation mimetic mcu mutants (mcu-yfs). we confirmed that only two tyrosine sites were phosphorylated in response to adren- ergic stimulation in situ using cell lines stably expressing mcu-yfs. in addi- tion, overexpression of these mcu-yfs failed to increase mitochondrial ca þ uptake in response to cytosolic ca þ elevation by thapsigargin, whereas wild- type mcu transfection dramatically accelerates mitochondrial ca þ uptake compared to non-transfected cells. in summary, mcu contains pyk -specific phosphorylation site(s) and pyk -dependent tyrosine phosphorylation of mcu can modulate its channel functions and regulate mitochondrial ca þ uptake. -pos board b cardioprotective roles of neuronal ca d sensor- during stress tomoe y. nakamura-nishitani

in cardiomyocytes often results in heart fail- ure. identifying molecular targets that regulate cardiomyocyte survival is of ther- apeutic importance. neuronal ca þ -sensor- (ncs- ) is an ef-hand ca þ - binding protein, which is important for excitable cell functions. we previously found that ncs- -deficient (ncs �/�) mice had excess neonatal mortality (circ. res. ).the aim ofthe present study isto examinewhether ncs- plays beneficial roles in cardiac survival during stress and the possible mechanisms un- derlying these effects. neonatal mouse ventricular myocytes orwhole hearts from wild-type (wt) and ncs �/� mice were subjected to stressors, and the resistance to stress was evaluated. ncs �/� mouse hearts were more susceptible to stress induced by oxidative impairment and ischemia-reperfusion injury. stress- inducedactivationofphosphatidylinositol -kinase (pi k)/akt signaling, a major survival pathway, was substantially reduced in the ncs �/�group, and overex- pressionofncs- ortheconstitutiveactive formofakt increased the survivalrate of ncs �/� myocytes. cellular atp levels, as well as mitochondrial respiration rates (both basal and maximal o consumption) were significantly depressed in ncs �/� myocytes; especially with oxidative stress. furthermore, intracellular ca þ handling was more easily dysregulated in stressed ncs �/� myocytes than wt myocytes. since ncs- levels were increased by stress, the data suggest that ncs- is a survival-promoting factor, which is upregulated by stress stimuli. interestingly, however,supra-physiological ncs-

development gisela beutner, george a. porter, jr. pediatrics, university of rochester medical center, rochester, ny, usa. mitochondria in early embryonic hearts are not thought to produce atp, yet they do produce reactive oxygen species (ros) that regulate myocyte differen- tiation. to assess changes in atp and ros generation in the developing heart, we measured mitochondrial oxygen consumption, the activity of the complexes (cx) and of the electron transport chain (etc), etc supercomplex assem- bly, and ros in embryonic mouse hearts. at embryonic day (e) . , mitochon- drial etc activity and oxidative phosphorylation (oxphos) are not coupled, even though the etc complexes are present. we show that cx- is able to accept electrons from the krebs cycle, but enzyme assays that specifically mea- sure electron flow to ubiquinone or cx- show no activity at this early embry- onic stage. at e . , mitochondria appear functionally more mature; etc activity and oxphos are coupled and respond to etc inhibitors. in addition, the assembly of highly efficient respiratory supercomplexes containing cx � , � , and � , ubiquinone, and cytochrome c begins at e . , the exact time when cx- becomes functional activated. at e . , etc activity and oxphos of embryonic heart mitochondria are indistinguishable from adult mitochon- dria. in contrast, generation of reactive oxygen species (ros), as measured with amplex red, is high at e . and drops significantly by e . , coinciding with activation of the etc. in summary, our data suggest that between e . and e . dramatic changes occur in the mitochondria of the embryonic heart, which result in a decrease of ros generation and an increase in oxphos due to the activation of cx- and the formation of supercomplexes. -pos board b the

mediated apoptosis are not fully understood. we found that bax insertion into the mom was the earliest apoptotic step inhibited by bcl overexpression. paradoxically, we also found that bax translocation to the mitochondria was not inhibited but rather spontaneously increased in this same genetic context. this increase in mitochondrial associated bax required a physical interaction be- tween bax and bcl . we therefore propose that, at least when upregulated, bcl behaves as a ‘decoy receptor’ which sequestrates bax at the mitochondria but inhibits its insertion into the mom, committing the cell to survive. supported by nyu research challenge funds to ld. -pos compartmentalization of bcl family proteins mediated by organelle lipid membranes rebecca j. boohaker, ge zhang, adina loosley, kathleen nemec, annette r. khaled. university of central florida, orlando, fl, usa. cancer is defined by a pronounced inhibition of cell death. the bcl family of proteins tightly regulates the delicate balance between life and death. one method of regulation is the compartmentalization of antagonistic members. for example, bax, a pro-apoptotic member of this family, acts as the penulti- mate factor in the apoptotic cascade by releasing apoptogenic factors such as cytochrome c from the mitochondrial lumen. the normally cytosolic protein translocates from one internal compartment to another through an elusive mechanism. individual organelles are defined not only by function (mediated by specific membrane bound proteins), but by the unique composition of their phospholipid membranes. in this work, we have evaluated the contribution of organelle lipids to the localization of of bcl proteins. -pos in search of the structure of mac in the mitochondrial outer membrane pablo m. peixoto , christian renken , shefali haldar , carmen mannella , kathleen w. kinnally . new york university college of dentistry, new york, ny, usa, wadsworth center, albany, ny, usa, academy of the holy names, albany, ny, usa. several groups have tried to determine the structure of the channel (mac) formed in mitochondrial outer membranes (om) of apoptotic cells or in syn- thetic membranes by bax and related proteins/peptides, using electron micros- copy (em), atomic force microscopy and x-ray diffraction. here, pore-like structures ~ - nm were handpicked from transmission em images of ura- nyl-acetate-stained oms isolated from control and apoptotic (il -deprived) fl . cells. these ‘‘candidate pores’’ were aligned by correlation procedures, and class averages defined by principal component and k-means analyses. main differences in the class averages were ( ) the presence of one or more dark (stain-filled) pores, and ( ) the nature of white (stain excluding) features around the pores. a class average consisting of a single -nm pore with pro- nounced white rim was rotationally averaged and used as a reference for cross-correlation searches of om images from control and apoptotic cells. searches using this -nm ‘‘donut’’ motif and the same motif doubled in size ( -nm ‘‘donut’’) yielded thousands of ‘‘hits’’ in both control and apoptotic membranes, which were subsequently aligned and classified as before. the pre- dominant stain-filled structures found with both motifs were not circular but elongated (up to ~ x nm), extending away from stain-excluding crescent- shaped features. the radial anisotropy ruled out reference bias and was in- consistent with pores formed by rings of evenly spaced protein subunits. we hypothesize that the different classes of structures detected represent stages in formation of mac as an increasingly large membrane bilayer defect (or ‘‘cleft’’) induced by successive aggregation or clustering of bax/bak molecules. a progressive assembly mechanism for mac has been recently suggested by real-time monitoring of mac conductances in isolated mitochondria by patch clamping (martinez-caballero et al. j biol chem : - ).

new york, ny, usa. accumulating literature associate mitochondrial dynamics with apoptosis, since regulation of either process has reciprocal effects. these processes seem to converge in formation of the mitochondrial apoptosis induced channel, mac, which releases cytochrome c and triggers the degradation phase of apo- ptosis. while bax and bak, core components of mac, were shown to interact with fusion and fission proteins, some studies also suggest proteins from the in- termembrane space could leak to the cytosol and further promote mitochondrial fission during apoptosis. the temporal relationship between apoptosis induc- tion, mac formation and mitochondrial fragmentation was investigated by time lapse microscopy. mac function was induced through staurosporine treat- ment and microinjection of tbid or cytochrome c. mac formation and mito- chondrial dynamics under these conditions were monitored in hela cells (clone ) that stably express low levels of gfp-bax and were transiently transfected with a pdsred- plasmid. gfp-bax relocation to mitochondria only during apoptosis signals mac formation, while pdsred- expression shows mito- chondrial structure as red fluorescence. treatment with staurosporine and microinjection with tbid or cytochrome c induced relocation of bax and col- lapse of the mitochondrial network. the temporal relationship between these two events was further analyzed. interestingly, pretreatment with imac , a spe- cific mac blocker, protected against cell death and prevented mitochondrial fragmentation after tbid injection. our results suggest a link exists between mac formation and collapse of the mitochondrial network during apoptosis. supported by nih grant gm . -pos mechanism of the mitochondrial cytochrome c release wave in bid-induced apoptosis soumya sinha roy, cecilia garcia-perez, erika davies, xuena lin, györgy hajnóczky. thomas jefferson university, philadelphia, pa, usa. bid, a bh -only bcl family protein, plays a central role in apoptosis. bid is cleaved by caspase- and other enzymes forming tbid that induce mitochon- drial outer membrane (omm) permeabilization and cytochrome c (cyto-c) re- lease. however a mystery remains how bid synchronizes the function of a large number of discrete organelles, particularly in mitochondria-rich liver or muscle cells. here we showed that tbid ( . - nm) elicited progressive omm perme- abilization and complete cyto-c release with a dose-dependent lag time and rate in h c cell populations. once started, the omm permeabilization was not pre- vented by tbid washout. in contrast, the dose-response for digitonin-induced omm permeabilization displayed quantal behavior. in single cell imaging studies, permeabilized h c and primary human cardiac cells transfected with cyto-c-gfp showed complete tbid-induced cyto-c-gfp release closely followed by mitochondrial depolarization. the cyto-c-gfp release started at discrete sites and propagated through the mitochondria with a constant velocity and a relatively stable kinetic of release in each organelle. similar tbid-induced cyto-c-gfp release wave was documented in intact h c cells transfected with tbid. the waves were not dependent on ca þ , caspase activation or permeabil- ity transition pore opening. however, treatment with mntmpyp, a ros scav- enger or overexpression of mitochondrial superoxide dismutase suppressed the coordinated cyto-c release and also inhibited tbid-induced cell death. on the other hand, both superoxide and hydrogen peroxide sensitized mitochondria to the tbid-induced permeabilization. thus, tbid engages a ros-dependent inter-mitochondrial signaling mechanism for spatial amplification of the apoptotic signal by mitochondrial waves. -pos role of milton domains in the calcium-dependent regulation of mito- chondrial motility sudipto das, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. the mammalian grif and oip , and the drosophila milton are kinesin- binding proteins that form a complex with the miro gtpase, an outer mitochon- drial membrane ef-hand protein, to support the movement of mitochondria along the microtubules. our study demonstrates that in h c cells overexpress- ing oip or grif , the basal motility of mitochondria is increased, whereas the sensitivity to calcium-induced movement inhibition is decreased. to dissect the interaction between milton, kinesin and miro, three different milton constructs were tested: milton ( - ), the soluble domain of milton; milton ( - ), lacking the kinesin heavy chain binding site and milton ( - ) that lacks additional ~ amino acid presumably containing part of the miro binding site. immunohistochemistry revealed that the overexpressed milton ( - ) was cytoplasmic, whereas the other two milton constructs showed mitochondrial localization. the basal mitochondrial motility was in- creased by milton ( - ) but was not altered by milton ( - ) or mil- ton ( - ). a plot of mitochondrial motility against slowly rising cytoplasmic [ca þ] induced by thapsigargin ( mm), shows that overexpression of milton ( - ) significantly reduced the calcium sensitivity of mitochondrial motil- ity reminiscent of oip and grif . by contrast, milton ( - ) or milton ( - ) did not have any effect. the thapsigargin-induced cytoplasmic calcium signal was not affected by any of the milton constructs. these data indicate that compartmentalization of bcl family proteins mediated by organelle lipid membranes in search of the structure of mac in the mitochondrial outer

% of women who had tumours that contained high levels of bag- had a longer survival time and were still alive years after diagnosis, compared with % of women whose tumours contained low levels of the

metastatic prostate cancer treatment is the suppression of hormones that fuel tumor cells. how- ever, almost all men with advanced prostate cancer develop resistance to these androgen-depleting therapies. recently, researchers showed that nearly % of patients with metastatic castration-resistant prostate cancer (mcrpc) have a genetic alteration that could be targeted by other clini- cal treatments. the fi ndings suggest individualized approaches for these patients (cell ; : – ). “this will have a major impact on how we move forward in [treating] this disease,” says johann de bono, md, a principal investigator in the study and head of the division of clinical stud- ies at the institute of cancer research in london, uk. “ninety-nine percent of our trials involve no patient prese- lection. with this information, we can now subdivide these patients, as we’ve done with breast and lung cancers.” in this fi rst multicenter, inter- national clinical trial, researchers conducted whole-exome and transcrip- tome sequencing of bone or soft-tissue biopsy samples from patients living with mcrpc. results showed that . % of the patients who had a genetic alteration had androgen recep- tor mutations, a fi nding in line with current understanding of the disease. more compelling, researchers found that of the nearly % of patients with genetic alterations, % had anoma- lies (other than androgen receptor mutations) that could be targeted by investigational or fda-approved drugs currently used for other cancers. among these alterations, almost % occurred in dna repair pathways. for instance, some tumors had brca or brca mutations, which, in ovarian and breast cancers, have shown sensi- tivity to parp inhibitors, drugs that interfere with dna repair and prevent tumor cells from dividing. in addition, researchers mapped more than a half dozen previously unknown genetic changes, such as mutations in the wnt signaling pathway, which leads to regulation of cell development and migration, and a pik cb mutation with cancer-activating effects similar to pik ca. they also found that % of patients with mcrpc had germline mutations. “this is a very important study on a number of fronts,” says karen knudsen, phd, director of the sidney kimmel cancer center at thomas jefferson university in philadelphia, pa, who was not involved in the study. “it’s the fi rst large study looking at the incurable stage of the disease, where the unmet clinical need is. the large cohort gives us confi dence and a much clearer picture of the drivers of disease, and they’ve uncovered new potential drivers that are targetable.” when the study is completed, research- ers will have mapped and sequenced the tumors of patients with mcrpc. amassing such data, says de bono, will lead to more targeted—and more afford- able—sequencing. “it will be critical to follow up with clinical trials that correlate clinical outcomes with molecular alterations,” says arul m. chinnaiyan, md, phd, a senior author on the study and direc- tor of the michigan center for trans- lational pathology at the university of michigan in ann arbor. “the longer- term goal is to have this information ahead of time and be able to direct patients in a more precise way to the best therapy.” ■ cellular backpackers deliver lymphoma drugs researchers have developed a new technique that enlists t cells to ferry chemotherapy drugs into tumors and that improves the effi ciency of drug delivery. cancer cells can elude chemo- therapy by hiding out in lymph nodes and other protected locations. even if a small amount of drug makes it to these refuges, it may not permeate the tissue to reach the tumor cells inside. researchers have tried to overcome these problems by having nanoparti- cles transport chemotherapy drugs, but not all tumors have the leaky blood vessels that enable the particles to leave the bloodstream and disperse into the tumor. people karen e. knudsen, phd, has been named director of the sidney kimmel cancer center at thomas jefferson university in philadelphia, pa, as well as chair of its department of cancer biology. she has been serving in these roles on an interim basis since january. an expert in the molecular basis of hormone-dependent prostate cancer, knudsen aims to prevent and treat the disease. her studies that identify tumor suppressor and hormone-receptor alter- ations have uncovered new targets for treating advanced disease and have led to innovative, biomarker-driven clinical trials. in addition, she is editor-in-chief of molecular cancer research. rolf apweiler, phd, and ewan birney, phd, have been appointed joint directors of the european molecular biology laboratory— european bioinfor- matics institute (embl-ebi), effective july . the european hub for big data in biol- ogy, embl-ebi is based on the wellcome trust genome campus in hinxton, uk. as part of embl, the institute collects, annotates, archives, and shares data from publicly funded life-science experiments with the global scientific community. apweiler and birney will continue to lead their respec- tive research groups. apweiler is involved in many internal col- laborations and initiatives, including the human proteome organization proteomics standards initiative. he has served on the editorial and advisory boards of several journals, and he has published more than papers and book chapters. birney played a vital role in annotating the genome sequences of the human, mouse, and other organisms. he led the analysis group for the encode project. his inter- ests include functional genomics and statisti- cal methods to analyze genomic information. e m b l -e b i e m b l -e b i rolf apweiler, phd ewan birney, phd on april , .

)은 후진국과 선진국, 사회주의와 자본주의 등 개 나라의 행복감을 측정 했다. 그 결과 경제 발전 단계와 사회체제와는 상관없이 소득이 높은 사람들이 높은 행복감을 나타냈지만, 일정 시점이 지나면 소득 수준이 더 높아져도 행복감은 더 이상 증가하지 않는다는 것을 발견해 경제규모나 소득수준이 반드시 국민 행복감과 일치하지 않는다는 ‘이스털린 역설 (easterlin paradox)’을 주장하고 gdp 한계를 지적한 바 있다. stiglitz 외( ) 역시 gdp와 같은 경제적 수치보다 삶의 질과 지속가능성에 대한 평가를 강조하고 gdp지표의 대안이 될 만한 적 절한 웰빙 지표를 개발해서 삶의 질을 실질적으로 개선할 것을 주장하고 있다(우성대, ). 차 용진( )은 이러한 gdp에 대한 비판에 대해 국내총생산이 한 국가의 경제력은 측정할 수 있 지만 국민의 행복감이나 사회발전 수준 등 보다 근본적인 부분에 대해서는 제대로 파악할 수 rachel fletcher division st. great barrington, ma usa rfletch@bcn.net keywords: thomas jefferson, descriptive geometry, geometric construction, octagon, root-two geometer’s angle thomas jefferson’s poplar forest abstract. a unique geometric construction known to thomas jefferson reveals a rich interplay of root-two geometric elements when applied to jefferson’s octagonal plan of poplar forest, his eighteenth-century villa retreat. thomas jefferson and classicism in colonial america, when buildings were typically “designed” by craftsmen and tradesmen, rather than architects, thomas jefferson was largely responsible for introducing the classical aesthetic to architecture. his designs reflect the neo-classical movement that emerged as humanism in renaissance europe, then flourished in the enlightenment from the s to the end of the eighteenth century. jefferson scholar fiske kimball considers that “directly or indirectly american classicism traces its ancestry to jefferson, who may truly be called the father of our national architecture” [kimball , ]. an “amateur” architect with no formal training, jefferson first became aware of classical architecture through books, then later gained first-hand experiences of ancient roman and eighteenth-century french buildings while serving as american minister to paris ( - ). he studied the written treatises of marcus pollio vitruvius, leon battista alberti, inigo jones, sebastiano serlio and others who relied on classical rules of architecture and mathematical techniques for achieving proportion [o’neal , ]. on architectural matters, jefferson is reported to have said that andrea palladio “was the bible,” even though he knew his buildings only through books. jefferson practiced the roman classical architecture of palladio and late eighteenth century france, and borrowed extensively from classical sources. he based the rotunda of the university of virginia in charlottesville on measured drawings of the pantheon published in giacomo leoni’s the architecture of a. palladio. models for the virginia state capitol in richmond, which he designed with the assistance of french architect and antiquarian charles-louis clerisseau, included the temple of balbec, the erechtheum in athens, and the ancient roman temple maison carrée at nîmes in france. this was the first government building designed for a modern republic, the first american work in the classical revival style, and the first modern public building in the world to adapt the classical temple form for its exterior [nichols , - ; kimball , ]. geometric proportion that jefferson followed classical rules for applying simple proportions involving whole numbers to the orders and other components of building design is well documented. but he also was familiar with techniques for achieving harmony through incommensurable ratios associated with elementary geometric figures. his designs often feature fundamental geometric shapes and volumes. the university rotunda, whose dome he describes as a “sphere within a cylinder,” presents an array of circles, squares and triangles. for the virginia capitol, he selected as sources “the most perfect examples of cubic architecture, as the pantheon of rome is of the spherical… .” the plans for his monticello residence present regular octagons, semi-octagons and elongated octagons. nexus network journal ( ) – nexus network journal – vol. , no. , doi . /s - - - ; published online june © kim williams books, turin rachel fletcher – thomas jefferson’s poplar forest there is some evidence that jefferson applied incommensurable proportions through geometric techniques. for the washington capitol he specified that neighboring properties “be sold out in breadths of fifty feet; their depths to extend to the diagonal of the square.” in other words, the lots conform to the incommensurable ratio : (“opinion on capitol,” november [ford - , vi: ]). his plan for the university rotunda expresses root-two, root-three, and perhaps even golden mean symmetries [fletcher ]. fig. . thomas jefferson, poplar forest, first floor plan. image (ca. ), inked, shaded and tinted by john neilson (atrributed). scale: about = . on heavy paper, not watermarked, with co-coordinate lines drawn by hand, x . .

]. jefferson first proposed the octagonal house for his pantops farm, north of monticello, as a future residence for his grandson francis eppes. but instead he realized the plan at poplar forest, one of his working plantations where eppes eventually settled. poplar forest is of brick construction and octagonal in plan, containing a central square space, flanked on three sides by elongated octagonal rooms. on the fourth side, a short entry hall divides a pair of smaller rooms. the central dining room is skylit and measures x x , a perfect cube. on the east and west, alcove beds divide the two main bedrooms into sections [chambers , -

resselmer from individualized treatment of sickle cell pain to precision medicine: a -year journey samir k. ballas abstract in the s, sickle cell pain was treated with trial and error approach by increasing or decreasing the dose of an opioid or switching from one analgesic to another. this approach was controversial with criti- cism and doubt about its usefulness. since then, advances in deter- mining the structure of opioid receptors and the role of the cyp enzymes in metabolizing opioids revealed that these anatomic and metabolic findings are not the same in all persons, thus explaining the variability in response to opioids among patients. thus, the “trial and error approach” has a scientific basis after all. keywords: sickle cell disease; pain; individualized treatment; per- sonalized medicine; precision medicine introduction an infliction in the life expectancy figure of patients with sick- le cell disease (scd) occurred around the middle of the s (fig. ). this minimal increase in life expectancy coincided with my appointment at thomas jefferson university as the associate director of the newly created adult sickle cell center. the number of adults at that time was small and the transition from pediatrics to adult programs was at the age of years. the trickle of patients increased gradually and we were faced with adolescent and young adult african american patients who were in a state of confusion. stripped from the protective sphere of the pediatric world and the empathy of their pediatric hematologists and the pediatric ancillary staff, they were in a state of fear, anxiety, depression and, worst of all, severe pain. the world of adults was abject, withdrawn, busy, and status oriented. the fact that most patients were barely educated, many without a high school degree, unemployed, mediocre health coverage, and dysfunctional family structure conferred a logarithmic dimension to the problem. their main hope was to have pain relief. the steady stream of admissions of patients with acute painful vaso-occlusive crises (vocs) to the emergency depart- ment (ed) and hospital were not welcome by most providers, hospital administration, the house and nursing staffs. there was subtle resentment of the patients that sometimes extended to the hematologists who showed compassion to the patients. soon labels such as drug addicts, drug-seeking behavior, and hospital hopping and frequent flyer emerged. listening to and believing the patients and keeping de- tailed records of ed and hospital admissions and the analge- sics prescribed, revealed that most patients genuinely do not respond to a certain analgesic or a certain dose. increasing the doses of an analgesic or switching to another drug solved the problem in most patients. soon it became obvious that man- agement of sickle cell pain should be individualized. accordingly and with the approval of the institutional re- view board (irb), i issued an identification wallet-sized, plas- ticized card that was carried by patients and presented to the provider treating their voc in the ed, hospital or any other medical facility. information printed on both sides of the card included: ) demographic data and a recent photograph; ) he- matological data including reticulocyte count; ) medical data including the type of scd, its complications and co-morbid- ities if present; ) all medications being taken by the patient and the recommended treatment of vocs including the name, dose, and the route of administration of the analgesics in ques- tion; and ) my name and contact information for answering questions if needed. it was not expensive to issue these cards. a polaroid camera available at that time and a laminator were the only equipments needed to issue these cards. information on the card was revised and updated annually. details of this endeavor were published in [ ]. with the advent of com- puterization later on, information on the card was computer- ized and a printed copy was given to the patient. reactions to the implementation of this card were mixed. patients and their families loved it. the patients were very compliant in carrying it as faithfully as they carry their medical cards. some providers liked it very much because it facilitated having a concise history about the patients. others denounced it as a gimmick that would allow patients to abuse the system. pharmacology of opioids while this controversy was brewing, interesting developments manuscript accepted for publication march , cardeza foundation for hematologic research, department of medicine, jefferson medical college, thomas jefferson university, philadelphia, pa , usa. email: samir.ballas@jefferson.edu doi: http://dx.doi.org/ . /jocmr w articles © the authors | journal compilation © j clin med res and elmer press inc™ | www.jocmr.org management evolution of sickle cell pain j clin med res. ; ( ): - in basic science were in progress to understand the pharmaco- dynamics and pharmacokinetics of opioids. foremost among these was the mechanism of action of opioids in relieving pain. in the s, it was hypothesized that opioids have receptors to bind to and activate in order to relieve pain [ ] by blocking or minimizing the transmission of painful stimuli and raising the pain threshold. it did not take long after that to identify opioids as ligands that bind to stereospecific and saturable re- ceptors in the central nervous system and other tissues [ , ]. these receptors are transmembranous g proteins with opioids as ligands [ ]. in addition, recent elegant studies [ - ] have revealed a helical structure of the opioid receptors, which forms pockets in which the corresponding opioid (ligand) fits snugly (fig. a, b). receptors mediate two major functions, chemical recog- nition and physiologic action. recognition is highly specific, such that only l-isomers of certain opioids exert analgesic activity [ ]. the binding affinity varies considerably among opioids [ ]. fentanyl, for example, has higher binding affinity than morphine [ ]. the binding affinities of opioids appear to correlate with their analgesic potencies [ ]. physiologically, by binding to receptors, opioids initiate a series of biochemi- cal events including activation of g proteins, inhibition of adenylate cyclase, and extrusion of potassium ions, resulting in hyperpolarization of cell membranes [ - ]; this delays or prevents transmission of painful stimuli. thus, the riddle why some patients respond to one opioid but not another had a pathophysiologic explanation [ ]. parallel to the progress in the pharmacodynamics of opi- oids mentioned above, a concomitant advance in the phar- macokinetics of opioids was bubbling to the surface. the metabolism of opioids includes two major phases [ , ]. figure . helical structure of opioid receptors.

( ): - phase i involves the cyp enzymes and phase ii metabolism conjugates the drug to hydrophilic substances, such as glucu- ronic acid, sulfate, glycine, or glutathione. glucuronidation is the most important phase ii reaction. it is catalyzed by the enzyme uridine diphosphate glucuronyltransferase (ugt). morphine, hydromorphone and oxymorphone are metabo- lized by glucuronidation, whereas the majority of the other opioids are metabolized by the cytochrome p isoenzyme system. the net effect of an opioid depends on the availability of enzyme(s) to convert it into metabolites that could be active or inactive. briefly, the cyp d genotypes are categorized into phenotypes based on the activity of the variant enzymes. ultrarapid metabolizers (ums) have greater than normal activ- ity due to duplication or triplication, of active alleles [ - ], extensive metabolizers (ems) have normal enzyme activity, intermediate metabolizers (ims) have decreased enzyme activ- ity, and poor metabolizers (pms) have absent or little enzyme activity. thus, fentanyl, for example, is normally metabolized into inactive metabolites. patients who are ums of fentanyl would rapidly convert it into inactive metabolites with mini- mal or absent analgesic effect requiring increasing the dose of fentanyl. on the other hand, patients who are pms of fentanyl would experience prompt relief with relatively small doses of fentanyl but higher doses could be toxic due to the accu- mulation of unmetabolized fentanyl [ ]. phase i metabolism of opioids involves primarily the cyp a and cyp d en- zymes. the cyp a enzyme metabolizes more than % of all drugs; consequently, opioids metabolized by this enzyme have a high risk of drug-drug interactions [ ]. conclusion together, current data on the pharmacodynamics and phar- macokinetics of opioids show great variability of genotypes among patients and extreme variability in individual responses to opioids. determining the pharmacogenetics profile of each patient facilitates the choice of drugs that would be efficacious for that patient and avoid those drugs associated with harmful drug-drug interaction. this approach in diagnostics and thera- peutics ushers in the dawn of a new field for the management of individual patients based on their unique pharmacogenet- ics, phenotypic and biomarker characteristics. this future ap- proach is referred to as personalized medicine or, more recent- ly, precision medicine [ ]. it has already been implemented for certain cancer patients receiving chemotherapy. we hope that this methodology would be approved and sponsored by the insurance companies for patients with scd. in the mean- time, listening, believing and respecting the patient with sickle cell pain should be maintained for now as the approach to in- dividualized therapy. acknowledgement supported in part by the adult sickle cell program of the com- monwealth of pennsylvania for the philadelphia region. conflict of interest the author declares no competing financial interests. references . ballas sk. treatment of pain in adults with sickle cell disease. am j hematol. ;

greatness survey brandon rottinghaus, university of houston justin s. vaughn, boise state university abstract  debates about presidential greatness have been with us for decades, facilitated in part by numerous systematic surveys of scholars with expertise in american history and politics. nevertheless, the voice of political scientists in this debate has been relatively muted when compared particularly with the role that historians have had in making these determinations. this article introduces and assesses results of a recent effort to capture the attitudes of political science presidency experts about presidential greatness. by surveying the membership of the apsa presidents and executive politics section, we could identify and then compare specifically the attitudes of political scientists against the growing body of ratings and rankings of a phenomenon with long-standing interest and importance. the debate about who our greatest presidents have been is an age-old parlor game that has been played since americans elected a president not named washington. over time, as the number of presi-dents eligible for entry into the greatness debate grew, various sub-debates also became possible. not only could disputants present arguments in favor of or against one pres- ident or another as the greatest in all history, they also could squabble about which was the greatest commander-in-chief; which had the highest integrity and greatest moral courage; and, of course, which most exhibited a serious lack of greatness. related to these new arguments, the very definition of presiden- tial greatness has been contestable and contested as american history—and american political values— evolves. the subject of presidential greatness, particularly from a modern political science perspective, is the focus of this article. the contested concept of presidential greatness and the various scholarly efforts to capture and analyze the phenomenon are discussed briefly. we then introduce results of a new study of presidential greatness based on a large sample of political scientists who are engaged in the ongoing study of the american presidency. results of this study underscore some of the findings we have come to expect based on decades of analysis primarily from historians. the study also yielded intriguing results poten- tially related to the distinct disciplinary perspectives of political scientists about the presidency that separates them from scholars in other fields. what is presidential greatness? arguably, there are as many—if not significantly more—perspectives on what it means to be a great president as there have been pres- idents. indeed, a cnn story that attempted to ultimately understand the concept instead further indicated the variety of opinions, even as it queried well-known historians with largely similar methodological approaches to the study of the office and the individuals who have held it (cnn ). for example, richard reeves stated, “presidential greatness is determined by being in the white house at the right time—or the wrong time. the presidency is a reactive job and we judge the presidents by their handling of one or two big crises, usually unforeseen.” similarly, joseph ellis noted that the nation’s three greatest presidents— george washington, abraham lincoln, and franklin roosevelt— came to office in times of great crisis. h. w. brands, however, took a broader approach than reeves and ellis’s focus on crisis man- agement, arguing that “great presidents are those who change the course of american history.” he pointed out andrew jackson’s brandon rottinghaus is a professor of political science at the university of houston. he can be reached at bjrottinghaus@uh.edu. justin s.

involvement of ordinary people in the political process, abraham lincoln’s reversal of secession and slave emancipation, franklin roosevelt’s founding of the welfare state and defeat of fascism, and ronald reagan’s dismantling of much of the regulatory state he confronted on election to the position in . joan hoff took a different approach to determining what the greatest presidents had in common, observing that nearly all of them regularly at the top of scholarly surveys led the nation in time of war (except thomas jefferson and theodore roosevelt); however, she notes that merely conducting a war alone is not sufficient. aida donald invoked various other criteria, ranging from accomplishments to sound decision making to personal character. that leading figures from the same discipline at the same moment in time could take such distinct approaches to presi- dential greatness reinforces the notion that whereas presidential greatness is frequently discussed, it has not been defined entirely. therefore, the fact that psychologists take an equally distinctive perspective should not be a surprise. in a paper presented to the american psychological association, rubenzer, faschingbauer, and ones ( ) focused on what the greatest presidents had in common. rather than identifying factors such as the presence of crisis or successful management of major wars, they focused on the presidents’ cognitive processes and behavioral attributes. they concluded that factors such as presidents being achievement- oriented and inclined to assert their interests are determinative. dean simonton, a psychologist who pioneered much of his dis- cipline’s presidency-focused research, instead identified factors more likely to resonate with political scientists: number of years in office, number of years as a wartime commander-in-chief, an administration scandal, an assassination, and entering office with a reputation as a war hero (simonton ). other recent political science research has shown that economic performance (curry and morris ), policy productivity (rottinghaus and vaughn ), and public demand for progressive leadership (nichols ) also explain assessments of presidential greatness, whereas the one commonly believed explanation—prior experience— does not (balz ). conversely, karl rove, who was george w. bush’s strategist and adviser, sounded more like a psychologist than a political operative when he opined on the subject during a speech at the university of utah. according to rove, presidential greatness is a function of a few essential factors: clarity of vision, clar- ity of direction, the presence of a crisis, emotional intelligence (a phrase that he acknowledged was borrowed from the work of fred greenstein), a respect for public opinion, the presence of a strong team of advisors, and a “readiness to act and a com- fort in deciding” (rove ). although many of these factors may sound as if they are from a george w. bush stump speech— one he would have participated in authoring—rove did a mas- terful job of linking explanations ranging from individual char- acteristics to institutional con- text (see also kenney and rice ) in a rather broadminded and transdisciplinary approach to the concept of presidential greatness. studying presidential greatness virtually all of the previously mentioned social science research designed to explain presidential greatness used the growing body of surveys conducted among both experts and the mass public. famed historian arthur m. schlesinger other recent political science research has shown that economic performance (curry and morris ), policy productivity (rottinghaus and vaughn ), and public demand for progressive leadership (nichols ) also explain assessments of presidential greatness, whereas the one commonly believed explanation—prior experience—does not (balz ). f i g u r e presidential greatness survey rank and knowledge   ps • july

t h e p r o f e s s i o n : p r e s i d e n t i a l g r e a t n e s s a n d p o l i t i c a l s c i e n c e pioneered the practice of surveying intellectual elites about their attitudes toward our greatest presidential leadership. n , life magazine published the results of his study of historians, which asked them to assign each president to one of five categories: great, near great, average, below average, and failure. abraham lincoln was the unanimous victor and, indeed, the only president to receive a “great” vote from every respondent (bose , ). fourteen years late, schlesinger conducted another survey, this time featuring historians, which was published in the new york times magazine. the results across these two studies were largely consistent, with the majority of presidential rank- ings remaining within a couple places of their counterparts. however, noteworthy exceptions included james monroe (- ranks, from to ), andrew johnson (- , from to ), chester arthur (- , from to ), and calvin coolidge (- , from to ). a few decades later, the new york times magazine recruited arthur m. schlesinger jr. to conduct another expert poll in . he also published an extended report in political science quarterly (schlesinger ). his method slightly departed from his father’s, however, because he decreased the number of respondents to and expanded the pool to include politicians governor mario cuomo and us senator paul simon. this makes a comparison imperfect but it provides insight into shifting perspectives on presidential greatness and how impressions of presidents have changed. the results of schlesinger jr.’s survey were consistent with the two conducted by his father; however, they provided evidence that several presidents experienced significant changes in reputation in the half-century since the first schlesinger poll was released. for example, presidents whose rankings dropped by more than five places between the surveys included john tyler (from to ), james buchanan (from to ), andrew johnson (from to ), ulysses s. grant (from to ), rutherford hayes (from to ), chester arthur (from to ), william howard taft (from to ), warren harding (from to ), and herbert hoover (from to ). dwight eisenhower’s rank increased, however, from in —when he had been out of office for less than two years—to in . by , the presidential rankings “cottage industry” had expanded to well beyond only the schlesinger family. between schlesinger sr.’s second study and schlesinger jr.’s first, there were several similar efforts, including a chicago tribune poll in and three polls produced by the siena research institute (sri) at siena college in , , and . since then, sri has conducted similar polls in and . in the years since the last schlesinger poll, there also have been two wall street journal-sponsored studies ( and ), two c-span studies ( and ), and various one-time studies conducted by news- week ( ), history news network ( ), the times of london ( ), and the united states presidency centre ( ) in london. some of these studies used more unorthodox methods or focused only on a segment of presidents, but all attempted to use the experts’ wisdom to put presidents in order of greatness. the net result has been not only a wide range of presidential- greatness surveys but also a change in the conversation about presidential leadership itself. indeed, mercieca and vaughn ( , ) suggested that the rising preponderance of these polls over time has affected the way that experts and ordinary citizens view presidential greatness as well as our greatest presidents (i.e., great presidents are heroes, not necessarily competent administrators). even with these decades of influential studies, however, assessments skew to the historical. to balance the exist- ing body of greatness studies, we developed and implemented a survey designed to capture politi- cal scientists’ attitudes toward our greatest presidents. presidential greatness, according to political scientists to develop the survey, we invited the entire membership of the apsa presidents and executive politics (pep) section (n = ) to participate in a qualtrics-based survey in early june . the survey was closed and data were collected on november , . during the survey time frame, we received complete responses, achieving a . % response rate. the resulting respondent pool varies meaningfully across several important indicators. for exam- ple, concerning ideology, . % of respondents identified as liberal, . % as somewhat liberal, . % as moderate, % as somewhat conservative, and . % as con- servative. similarly, . % con- sidered themselves a member of the democratic party, compared f i g u r e presidential skill ratings ps • july ......................................................................................................................................................................................................................................................................................................................... with . % for the republican party and . % for independents. of the respondents, % were affiliated with public institutions compared to % with private institutions; . % were affiliated with research institutions compared to % from teaching insti- tutions; and . % were affiliated with institutions that combined research and teaching emphases. the majority of respondents were full-time faculty members, with % of the pool consisting of full professors, . % associate professors, and . % assistant pro- fessors; . % were emeritus faculty; . % were adjunct or instruc- tional faculty; and . % were graduate students. respondents’ pedigrees included . % who received their highest degree from an ivy league institution compared to . % from a state flagship institution, . % from an elite private institution, and . % from a non-flagship public institution. finally, . % of respondents were male and . % were female. in addition to these demographic details, respondents were queried about their knowledge of and opinions about american presidents in various ways. they were asked on a scale of to how much information they knew about each president ( = nothing; = a lot). the resulting scores were averaged; over- all, respondents indicated the greatest familiarity with barack obama, george w. bush, and bill clinton, followed by ronald reagan, abraham lincoln, lyndon johnson, and richard nixon. they were least familiar with millard fillmore, franklin pierce, benjamin harrison, zachary taylor, and chester arthur. in general, the earlier a president had served, the less information political scientists knew about him. notable exceptions included popular and historically consequential presidents. each respondent also was given the opportunity to rate indi- vidual presidents on a -to- scale concerning their overall greatness. importantly, the survey did not stipulate a particular definition of greatness other than a brief indication that = failure, = average, and = great. the resulting scores were averaged across all respondents. abraham lincoln had the highest overall greatness ranking, followed by george washington and franklin delano roosevelt. the next tier of greatness included presidents theodore roosevelt, thomas jefferson, harry truman, and dwight eisenhower. the least great president was james buchanan, fol- lowed by warren harding, andrew johnson, franklin pierce, and william henry harrison. of the modern presidents, bill clinton earned the highest overall greatness rating and george w. bush earned the lowest. between these two were ronald reagan (no. with . %), lyndon baines johnson (no. with . %), john f. kennedy (no. with . %), george h. w. bush (no. with . %), barack obama (no. with . %), gerald ford (no. with . %), jimmy carter (no. with . %), and richard nixon (no. with . %). figure provides additional information about overall greatness ratings and rankings for each president, including both the rank in the pep membership study and an average rank across the six other major scholarly survey stud- ies conducted between and the pep study. this range of years was included because it balances several studies to aver- age across with a consistent grouping of presidents in each survey. all presidents through george w. bush were rated in each study, and barack obama is rated in one study. the six studies include the wall street journal’s and studies; siena college’s and studies; c-span’s study; and the united states presidency centre study, which surveyed united kingdom–based experts in american political history. by calculating the average rank of each president across the past six scholarly surveys, we could compare the political sci- ence perspective, as captured in the pep study, with an aggregated representation of largely (although not exclusively) historian-based studies. for most presidents, the pep ranking is consistent with the previous average ranking. indeed, for of the individual presidents (i.e., grover cleveland is counted only once), the pep ranking was within three slots (plus or minus) of the previous average ranking; for presidents, it was within . slots (plus or minus). the pres- idents for which there was a pep ranking of a three or more slots difference (plus or minus), however, yielded some interesting observations. bill clinton is easily the main outlier, with the pep study ranking him . slots higher than f i g u r e who should be the next president on mount rushmore? of the modern presidents, bill clinton earned the highest overall greatness rating and george w. bush earned the lowest. between these two were ronald reagan (no. with . %), lyndon baines johnson (no. with . %), john f. kennedy (no. with . %), george h. w. bush (no. with . %), barack obama (no. with . %), gerald ford (no. with . %), jimmy carter (no. with . %), and richard nixon (no. with . %).   ps • july

t h e p r o f e s s i o n : p r e s i d e n t i a l g r e a t n e s s a n d p o l i t i c a l s c i e n c e his previous average. his predecessor, george h. w. bush (+ ), was the only other president in this group to rank higher in the pep study than the previous average ranking. every other noteworthy disjuncture represents an instance in which f i g u r e “best” and “worst” president total votes f i g u r e most “underrated” and “overrated” president the pep study ranked pres- idents several points lower than their previous average ranking, including james polk (- . ), herbert hoover (- . ), richard nixon (- . ), george w. bush (- . ), grover cleveland (- . ), william mckinley (- . ), james monroe (- . ), chester arthur (- . ), and warren harding (- . ). moreover, of these nine presi- dents, only richard nixon and george w. bush can be considered modern presidents, and both were among the most controversial and derided of all presidents in american history. the remaining presidents who compared nega- tively are premodern presidents, with more than half from the nineteenth century. from these observations, we tentatively con- cluded that political science experts on the american presidency— focused as they largely are on the modern presidency—were more likely to penalize premodern pres- idents for their lack of centrality to the contemporary institution in the form of lower greatness rat- ings. conversely, four of the most recent eight presidents have the biggest discrepancies between the pep study and their previ- ous average, suggesting their his- torical reputations are still in flux. this is underscored by the fact that two of the four presidents (i.e., bill clinton and george w. bush) were still in office when one or more of the studies included in the comparison average were conducted. because most political science research regarding presidential politics focuses on the modern era, several questions were asked to gauge respondents’ opinions about specific dimensions of presidential leadership concerning presidents only from theodore roosevelt to barack obama. scholars debate the onset of the modern presi- dency, but roosevelt’s expansion of the influence and power of the office and roots of institutionaliza- tion of the office took place during his presidency. this allowed us to narrow the scope to shorten the survey. these questions focused on the following dimensions: the president’s legislative skill, diplomatic skill, military skill, and integrity and whether he was a champion ps • july ......................................................................................................................................................................................................................................................................................................................... of the people. higher scores mean that the presidents rank higher ( better) on these dimensions. figure displays these character- istics by president. lyndon johnson ( ) and franklin roosevelt ( ) score the highest on legislative skill, befitting their significant legislative accomplishments while in office. presidents eisenhower and theodore roosevelt scored highest on military skill, and both roosevelts, eisenhower, and nixon ranked in the top four for dip- lomatic skill. for integrity, eisenhower, truman, and carter topped the list, whereas nixon ( ) and harding ( ) were at the bottom. clinton, impeached by congress but not removed, scored . cousins franklin and theodore roosevelt were at the top of those presidents deemed “champions of the people”—fdr received the highest score of any president ( ) on any dimension. truman was third ( ) and immediately below him was lyndon johnson ( ). in addition to being asked about their knowledge and assessment of the overall greatness of each president, respondents replied to several other questions designed to approach the idea of presiden- tial greatness from multiple perspectives. for example, one ques- tion asked which president they would add to mount rushmore. as depicted in figure , the overwhelming choice was franklin delano roosevelt, who was selected by . % of respondents when asked which president (hypothetically) should be placed next on the monument. the next highest choices were ronald reagan and dwight eisenhower ( . % each), followed by andrew jackson and lyndon johnson ( % each), john f. kennedy ( . %), and barack obama and james madison ( % each). other presidents receiving votes included john adams, james k. polk, woodrow wilson, bill clinton, ulysses s. grant, william mckinley, calvin coolidge, harry truman, richard nixon, and george w. bush. respondents also were asked to identify which presidents were the best/worst, most over/underrated, and most/least polarizing. for each question, they were asked to drag and then rank multiple presidents into a box to identify their corresponding assessments. the results of how frequently each president was specified as “best” or “worst” for each question are reported in figure . we then exam- ined the “top ” for both the best and worst presidents. regarding which presidents were the best and which were the worst, abraham lincoln was included in a respondent’s top list times, fol- lowed by franklin delano roosevelt ( ), george washington ( ), theodore roosevelt ( ), and thomas jefferson ( ). con- versely, james buchanan made the worst list times, followed by warren harding ( ), andrew johnson ( ), richard nixon ( ), and george w. bush ( ). it is interesting that the aggregate results of the respondents’ attitudes toward a few presidents indi- cated a degree of ambivalence; for example, scholars included ronald reagan in their top , whereas others included him in their worst . similar patterns emerged for andrew jackson ( best, worst), woodrow wilson ( best, worst), lyndon johnson ( best, worst), and barack obama ( best, worst). respondents also were asked to identify the five most “over- rated” and five most “under- rated” presidents (figure ). john f. kennedy was included on the most overrated list ( ), followed by ronald reagan ( ), andrew jackson ( ), woodrow wilson ( ), and thomas jefferson ( ). conversely, the most underrated president was dwight eisenhower ( ), followed by george h. w. bush ( ), harry truman ( ), james polk ( ), and john adams and gerald ford (tied at ). although they tied with votes for most underrated, the respond- ents demonstrated significantly f i g u r e most and least polarizing presidents we then asked respondents to identify the five most and least polarizing presidents. as shown in figure , george w. bush was included in the list of most polarizing presidents times, followed by barack obama ( ), andrew jackson ( ), abraham lincoln ( ), and richard nixon ( ).   ps • july

gerald ford did not make any most overrated list. other presidents exhibiting similar patterns included barack obama ( most overrated, most underrated), james madison ( most overrated, most underrated), bill clinton ( most overrated, most underrated), ulysses s. grant ( most overrated, most underrated), and george w. bush ( most overrated, most underrated). we then asked respondents to identify the five most and least polarizing presidents. as shown in figure , george w. bush was included in the list of most polarizing presidents times, followed by barack obama ( ), andrew jackson ( ), abraham lincoln ( ), and richard nixon ( ). by far, george washington was the least polarizing president, making that list times, followed by dwight eisenhower ( ), james monroe ( ), john f. kennedy ( ), and abraham lincoln ( ). lincoln made the top list for both most and least polarizing presidents, but he was not the only president in which the aggregate results indicated scholarly uncertainty: franklin roosevelt was viewed as one of the five most polarizing presidents by respondents and also as one of the five least polarizing presidents by different respondents. similar patterns emerged for ronald reagan ( most polarizing, least polarizing), thomas jefferson ( most polarizing, least polarizing), john adams ( most polarizing, least polarizing), and harry truman ( most polarizing, least polarizing). conclusion our survey of political scientists regarding presidential greatness puts them back into the discussion about presidential greatness. in the judgment of our respondents, the destiny of some presi- dents has been altered as compared to similar previous surveys: presidents clinton and eisenhower rose to the top whereas president andrew johnson sank to the bottom. a new, expanded mount rushmore would have a slightly more republican flavor: most scholars would include presidents reagan and eisenhower but only after adding franklin roosevelt’s famous jutting chin. president kennedy was judged to be the most overrated whereas presidents eisenhower and george h. w. bush were the most underrated. for the two most recent presidents (i.e., bush and obama), neither fared well in general but partisanship emerged because liberals were more likely to rank obama higher and con- servatives were more likely to rank bush higher. reflecting on the benefaction of presidents past, these results reminded us that history is always shaping and reshaping the leg- acy of former presidents. as new problems and policies emerge, we are obliged to reassess presidential greatness in the context of those who are currently making history. rising historical great- ness in the opinion of our political science respondents appears to be a compounding of time and longevity in office, combined with economic prosperity and effectively handling an international conflict. presidential greatness in more recent surveys appears to be as much about successful management of complex national problems as the promotion of big ideas (although these may be related). this combination just might result in a president’s face being etched for eternity in a future stone monument. acknowledgments the authors thank steven schier for his support in conducting this survey during his term as president of the apsa presidents and executive politics section;

weakness and denervation atrophy of voluntary muscles. the disease often develops around middle life and inexorably progresses to paralysis [ , ]. although most als cases are sporadic, familiar als (fals) accounts for to % of cases with an autosomal dominant pattern of inheritance. transactive response dna-binding protein (tdp- ) is a heterogeneous nuclear rna binding protein encoded by tdp- gene. tdp- plays important roles in multipro- tein/rna complex and regulating gene expression [ ]. tdp- has been shown to promote neurodegeneration by impair- ing chromatin remodeling, accelerate

pathogenic mutation of tdp- causes an inherited form of als [ ]. mutation of tdp- gene has been identified re- sponsible for some familiar als. including m v muta- tion, no less than pathogenic tdp- mutants have been reported so far [ ]. using a tet-off system, inducible expression of human tdp- with a pathogenic mutation (m v substitution) successfully induced progressive paralysis in transgenic rats [ ]. the removal of mutant tdp- partly restored motor function in als rats expressing the causative gene in neu- rons and muscles, indicating that the motor neuron degenera- tion is partially reversible [ ]. however, it is unclear whether neurologic deficiency caused by mutant tdp- is correlated with the time of its expression. to address this question, we used tet-off system to produce inducible gene expression in transgenic rats, and the consequence events including the onset age and severity of illness were assessed in transgenic models. our findings support the hypothesis that earlier expression of mutant tdp- can cause a more aggressive phenotype of als in transgenic rats. - / $ . +. © bentham science publishers current neurovascular research, , vol. , no. chen et al. . materials and methods . . generation of transgenic rats the animal use protocol was approved by the ethical re- view board from thomas jefferson university, pa, usa. transgenic rats were established and maintained in a spra- gue dawley background. the tdp- gene was isolated from bac clone (rp - b ), and an m v substitu- tion was integrated into tdp gene by homologous recombi- nation in escherichia coli [ ]. tetracycline (tet)-inducible transgenic rats carried a mutant human tdp- (tdp- m v) transgene at the control of a tet-responsive element (tre) [ ]. selected cytomegalovirus enhancer fused to chicken beta actin promoter (cag) was used to drive tet- responsive transactivator (tta) gene. tre-tdp- m v transgenic rats were crossed with cag-tta positive rats. to selectively induce human tdp- gene expressed in rats, breeding rats and transgenic offspring were drunk with dox ( ug/ml) to inhibit transgene expression during embryonic and postnatal phase. then cag-tta/tre-tdp- m v double transgenic rats were deprived of dox to activate mu- tant tdp gene. the time of withdrawal of dox (dox-) was selected as -day-old and -day-old, to mimic the juvenile stage and adulthood of rats. . . behavioral tests and disease stages the onset and progression of the als phenotypes in transgenic rats were detected by mobility and grip strength. mobility was surveyed by open field test (med associates), which measured the total distance a rat travelled within min [ ]. grip strength was measured with a grip-strength meter (columbus instruments). we defined the disease onset as an irreversible reduction in travelled distance. paralysis was defined as dragging of legs or an inability to retract in- dividual legs. disease end stage was defined as the inability to retract two or more legs, or inability to right itself when the rat was placed on its side, or as a severe weight loss. re- lated data were compared using unpaired t-tests. p-value < . was regarded as statistically significant. . . immunofluorescence, immunohistochemistry and cresyl violet staining coronal forebrain sections and cross-sections of spine were used for immunohistochemistry and cresyl violet stain- ing. the colocalization of human tdp- with neun was detected by double-labelling immunofluorescence. primary antibodies used for immunofluorescence were; anti-human tdp- (abnova, clone e -d ), polyclonal antibody against neun from rabbits immunized with a peptide (maqpyppaqyppc) and affinity purified. immunostained tissues were visualized using a nikon microscope, and im- ages were acquired using a nikon digital camera as previ- ously reported [ ]. motor neurons in the spinal cord were observed by cresyl violet staining and quantified as previ- ously reported [ ]. the motor neurons in a long segment of lumbar cord (l -l ) were assessed to increase the accuracy of cell counting. the central segment of lumbar cord was cut into -um thick sections using a freezing microtome, and motor neurons were counted in every th section on both sides using a fractionator-based stereology software (stere- ologer). numbers of neurons were compared using unpaired t-tests. p-value < . was regarded as statistically signifi- cant. . . histology and histochemistry in skeletal muscles fresh gastrocnemius muscles were quick-frozen in isopentane/liquid nitrogen, then cut into cross sections ( �m) on a cryostat microtome. the structures of muscle were assessed by h&e staining, histochemistry for nonspecific esterase and atpase. nonspecific esterase activity was de- tected using a-napthyl acetate protocol. myosin atpase staining (ph . ) was used to discriminate three types of skeletal muscle fibers. . results . . tdp- transgenic rats had worse phenotype to examine whether mutant tdp- expressed in neu- rons could induce als-like phenotypes, we chose the regu- latory promoter of cag gene to control the activation of transgene and established cag-tta/tre-tdp- m v dou- ble transgenic rats, with their mutant human tdp- gene under the control of a tetracycline (tet)-responsive element (tre). then, we used the tet-off system to regulate the ex- pression of mutant tdp- in neurons. dox was used to in- hibit transgene expression during embryonic and postnatal phase. to mimic mutant tdp- expression in juvenile stage or adulthood, transgenic rats were deprived dox (dox-) at the age of days or days, respectively. both the groups of cag-tta/tre-tdp- m v double transgenic rats suf- fered from progressive weakness after dox (fig. a, b). in the group of dox- at the age of days (dox- days), transgenic rats began losing grip strength and mobility as early as days after dox- ( . ± . days after dox-), while the counterpart rats with dox- at the age of days (dox- days) developed early signs of paralysis (disease onset) not until days after dox- ( . ± . days after dox-) (fig. c-f). there were significant differences in the time of onset between the two groups (fig. a, b). . . severe loss of neurons in transgenic rats in the cortex and dentate gyrus, double-label fluores- cence staining demonstrated that mutant human tdp- was colocalized with the neurons (fig. a, b). cag-tta/tre- tdp- m v double transgenic rats showed apparent expres- sion of tdp- at the disease end stage, while tdp- was not detected in normal rats with matched age (fig. c). to accurately estimate motor neuron death in rats, we used un- biased stereological cell counting to count the number of motor neurons in a long segment of spinal cord (l -l ). compared with normal rats, stereological cell counting iden- tified more loss of neurons in transgenic rats with dox- at the age of days than in rats with dox- at the age of days (fig. ). . . neurogenic damages in transgenic rats as an outcome of motor neuron degeneration, we exam- ined skeletal muscle atrophy by h&e staining (fig. a , b ), and performed immunohistochemistry for nonspecific esterase (fig. a , b ) and

(accepted april ) short reports "scalded mouth" caused by angiotensin-converting-enzyme inhibitors captopril, an angiotensin-converting-enzyme inhibitor, is used to treat resistant hypertension.' side effects include rash, proteinuria, leukopenia, ageusia, angio-oedema, and aphthous and tongue ulcers; its sulphydryl moiety may be an aetiological factor.' enalapril, a new converting-enzyme inhibitor, does not contain a sulphydryl group. we describe three patients who reported a scalded sensation of the oral mucosa during treatment with captopril or enalapril. case reports case -a -year-old hypertensive woman receiving hydrochloro- thiazide mg daily was prescribed captopril - mg thrice daily in addition; she took no other medication. after two weeks the dosage of captopril was increased to mg thrice daily. six days later she complained of a burning sensation on the upper surface of her tongue, comparable to having been "scalded by a hot liquid," though she had no recollection of such an occur- rence. examination of her tongue and mouth was unremarkable. she re- ported no alteration in taste. with her consent the regimen was continued, the symptom persisted for five days and then dissipated despite two additional weeks of captopril treatment, without subsequent recurrence. case -during a research study a -year-old man with essential hyper- tension received enalapril mg twice daily. seven days later he said that his tongue and mouth felt as though they had been "scalded by coffee or pizza," though he could not recall such an occurrence. examination of the mouth showed only periodontal disease and questionable hyperaemia; neurological evaluation including taste perception was normal. he took no other medications. he continued treatment with enalapril for four additional days without resolution. the symptom abated, however, when enalapril was stopped, and he was treated with hydrochlorothiazide mg/day. two weeks later enalapril was restarted in a dose of mg daily, the diuretic being con- tinued. on the twelfth day of treatment he again complained of the "scalded- mouth" sensation, which was similar to but milder than the first episode. this continued for the next two days but abated when enalapril was stopped at the end of the trial. similar symptomatology did not recur. case -a -year-old hypertensive woman taking propranolol mg and hydrochlorothiazide mg daily was prescribed captopril mg thrice daily in addition. other medications included nitroglycerine and isosorbide dinitrate. after two weeks the captopril dosage was increased to mg thrice daily. nine weeks later she complained of a burning sensation in her throat, palate, and tongue. examination of the mouth was unremarkable. after two additional weeks of treatment with captopril the symptoms persisted and mild injection at the margins of the soft palate was noted; there was no alteration in taste. because of continued discomfort captopril was stopped with a distinct improvement during the next week; slight discomfort, however, localised to the tip of her tongue, persisted. comment although disorders of taste as well as aphthous and tongue ulcers have been reported during captopril treatment, the symptom de- scribed by our patients has not, to our knowledge, been previously associated with use of either captopril or enalapril. the mechanism of this side effect is unclear. neither fever nor eosinophilia accompanied the patients' complaints. no concomitant laboratory abnormalities were noted, and all the patients had normal renal function. since the side effect was noted with both captopril and enalapril the aetiology of this scalded-mouth reaction appears to be independent of the sulphydryl moiety of captopril. the hyperaesthesia of the oral mucosa abated during continued treatment with captopril in case , recurred o n a p ril b y g u e st. p ro te cte d b y co p yrig h t. h ttp ://w w w .b m j.co m / b r m e d j (c lin r e s e d ): first p u b lish e d a s . /b m j. . . o n ju n e . d o w n lo a d e d fro m http://www.bmj.com/ british medical journal volume june on rechallenge with enalapril in case , and was troublesome enough to require captopril treatment to be stopped in case . doctors treating patients with converting-enzyme inhibitors should be aware of the potential occurrence of this side effect. requests for reprints should be addressed to: dr peter h vlasses, clinical pharmacology (m- ), thomas jefferson university hospital, th and walnut streets, philadelphia, pa , usa.

infection cytomegalovirus commonly causes intrauterine infection. finding a primary or reactivated cytomegalovirus infection in the mother by isolating the virus from the throat, urine, cervix, or blood, or by maternal serology, does not necessarily indicate that the fetus will be infected. fetal infection appears to occur in no more than - % of even primary maternal infections. the presence of intrauterine infection has been established by culture of cytomegalovirus from amniotic fluid,' but such isolation may be time consuming. we report a case that shows that the availability of a sensitive radioimmunoassay for the detection of cytomegalovirus-specific jgm and the ability to obtain fetal cord serum mean that intrauterine serological diagnosis is possible. case report a -year-old rhesus-positive woman without atypical antibodies was referred at weeks' gestation after ultrasonography showed a hydropic fetus. she had felt well throughout the pregnancy, denied taking any medication, and reported no relevant personal or family history. at weeks' gestation an ultrasound scan had confirmed her dates and shown no major structural abnormalities. examination was unremarkable, with fundal height being consistent with dates. a further ultrasound scan confirmed a single fetus with gross ascites, but no other abnormalities were observed. fetoscopy was carried out and ml pure fetal blood and ml ascitic fluid collected. fetal serum showed appreciable hypoalbuminaemia of g/l (normal ± sd g/l (unpublished)). a fetal blood film showed severe erythroblastosis. a follow-up ultrasound scan showed re-collection of the ascites. intra- vascular fetal albumin infusion was planned but precluded by spontaneous premature rupture of the membranes at weeks' gestation. a conservative policy was adopted but labour ensued and a g severely depressed male infant delivered. resuscitative attempts were stopped after minutes. initial serology for cytomegalovirus on maternal sera showed an antibody titre of when a complement fixation test was performed on sera collected at weeks' and weeks' gestation. no cytomegalovirus-specific igm was detected in the fetal serum using indirect immunofluorescence (electro- nucleonics laboratories inc, maryland, usa). necropsy showed non-icteric hydrops fetalis (figure). macroscopically the only abnormal findings were a large liver with a finely nodular and mottled surface and massive ascites causing gross elevation of the diaphragm with consequent pulmonary hypoplasia. microscopy showed cytomegaly and intranuclear "owl's eye" inclusions in many organs, particularly the kidney (figure). the appearance was typical of cytomegalic inclusion disease. the liver showed extreme active erythropoiesis. cytomegalovirus was isolated from urine obtained at necropsy. ,,~~~~ .: ....i > .._ : i i! t . cm male fetus of g showing gross hydrops fetalis. inset: kidney showing cytomegalic cells with inclusion bodies. haematoxylin and

a fetus of this gestation as stated by alford et al. radio- immunoassay for cytomegalovirus igm showed that the fetal serum had a titre of . this is within the range seen in neonatal or cord serum from confirmed cases of symptomatic congenital cytomegalovirus. examination of the maternal serum for cytomegalovirus-specific igm by radioimmunoassay showed a titre of in the serum taken at weeks' gestation, but such igm was absent at weeks. these results were compatible with a primary infection occurring early in the pregnancy. comment cytomegalovirus is a recognised cause of hydrops fetalis, and intra- uterine cytomegalovirus infection was confirmed in this case by his- tology and isolation of the virus. initial serology for cytomegalovirus specific igm on fetal cord serum obtained at weeks' gestation was negative using an indirect fluorescence assay. when a sensitive radio- immunoassay was used, cytomegalovirus-specific igm was detected with ease, showing the increased sensitivity of this procedure for diagnosing congenital cytomegalovirus. we believe this to be the first case in which virus-specific igm has been shown in fetal serum ob- tained in utero. this work was supported

https://www.cambridge.org/core mac inhibitors neutralize the pro-apoptotic effects of tbid wednesday, february , a like ursodeoxycholic acid (udca) and tauroursodeoxycholic acid (tudca), are cytoprotective and inhibit cell death. the mechanisms associated with these distinct effects are not entirely clear. however, the effect of hydrophilic bile acids seems to be related with the blockage of a series of processes that converge on mitochondrial damage. bax is a pro-apoptotic protein that belongs to the superfamily of the bcl- proteins and is involved in mitochondrial pore formation. submicellar concentrations of cytoprotective bile acids have been shown to modulate bax concentration in mitochondria, suggesting that these molecules may interact directly with the protein. in this study, our objective was to evaluate the affinity of bile acids to recombinant bax protein, making use of fluorescence spectroscopy (fret and fluorescence anisotropy), as well as fluorescence correlation spectroscopy (fcs). our results show that the cytoprotective bile acids udca and tudca associate with recombinant bax protein with high affinity, while the cytotoxic bile acid dca only seems to be able to adsorb to the protein with much lower affinity. notably, the bind- ing site for udca seems to be located in a hydrophobic pocket of the protein. this interaction could be responsible for the disruption of bax translocation to the mitochondrial outer membrane in the presence of udca and/or tudca. supported from fct/portugal (projects ptdc/qui-biq/ / and reci/ctm-pol/ /

initial characterization of the imacs, different di-bromocarbazole derivatives with anti-apoptotic function have been developed and tested in several mouse models of brain injury and neurodegeneration [ - ]. owing to the increased therapeutic potential of anti-apoptotic di-bromocarbazole de- rivatives, we sought to expand our knowledge of the mechanism of action of these small molecule inhibitors. we investigated the kinetics of mac inhibi- tion in mitochondria from wild type, bak, and bax knockout cell lines using patch clamp electrophysiology, fluorescence microscopy, elisa, and quantita- tive western blot analyses. our results show that imacs work through at least two mechanisms: ) by blocking relocation of the cytoplasmic bax protein to mitochondria and ) by disassembling bax oligomers in the outer membrane. a comparison of the inhibitory effects over channel conductance and cyto- chrome c release suggests that the imacs interacted with both bax and bak with similar kinetics. interestingly, wild type mitochondria were more suscep- tible to inhibition than the bak or bax knockouts. a quantitative western blot analysis showed that wild type mitochondria had lower steady state levels of bak, which suggests an uneven stoichiometry of the mac components. -pos board b tyrosine phosphorylation of mitochondrial ca d uniporter regulates mitochondrial ca d uptake jin o-uchi, stephen hurst, jyotsna mishra, xiaole xu, bong sook jhun, shey-shing sheu. depariment of medicine, center for translational medicine, jefferson medical college, thomas jefferson university, philadelphia, pa, usa. mitochondrial ca þ has a critical role for balancing cell survival and death. ca þ influx into mitochondrial matrix is mediated primarily by the mitochondrial cal- cium uniporter (mcu). however, the signaling pathways that regulate mcu channel functions via post-translational modifications of mcu are completely unknown. here we show that adrenergic signaling induces mcu tyrosine phos- phorylation and accelerates mitochondrial ca þ uptake in cardiac cells. adren- ergic signaling induces activation of proline-rich tyrosine kinase (pyk ) and translocation into the mitochondrial matrix; enhancing the interaction between pyk and mcu, which subsequently accelerates mitochondrial ca þ uptake via pyk -dependent mcu tyrosine phosphorylation. mcu contains tyrosine res- idues ( in the n-terminus, in the pore-forming region, in transmembrane do- mains and in the c-terminus), which are conserved across all eukaryotic species. among them, only of these tyrosine residues (y at n-terminus, y , and y at c-terminus in mouse mcu) remained as potential phosphor- ylation candidate sites for protein tyrosine kinases using phosphorylation predic- tion programs. we mutated these tyrosine residues to phenylalanine and generated non-phosphorylation mimetic mcu mutants (mcu-yfs). we confirmed that only two tyrosine sites were phosphorylated in response to adren- ergic stimulation in situ using cell lines stably expressing mcu-yfs. in addi- tion, overexpression of these mcu-yfs failed to increase mitochondrial ca þ uptake in response to cytosolic ca þ elevation by thapsigargin, whereas wild- type mcu transfection dramatically accelerates mitochondrial ca þ uptake compared to non-transfected cells. in summary, mcu contains pyk -specific phosphorylation site(s) and pyk -dependent tyrosine phosphorylation of mcu can modulate its channel functions and regulate mitochondrial ca þ uptake. -pos board b cardioprotective roles of neuronal ca d sensor- during stress tomoe y. nakamura-nishitani , shu nakao , shigeo wakabayashi . molecular physiology, natl.cer.cardiovasc.ctr., suita, japan, cardiac physiology, natl.cer.cardiovasc.ctrwakabayshi, suita, japan. dysregulation of ca þ homeostasis in cardiomyocytes often results in heart fail- ure. identifying molecular targets that regulate cardiomyocyte survival is of ther- apeutic importance. neuronal ca þ -sensor- (ncs- ) is an ef-hand ca þ - binding protein, which is important for excitable cell functions. we previously found that ncs- -deficient (ncs �/�) mice had excess neonatal mortality (circ. res. ).the aim ofthe present study isto examinewhether ncs- plays beneficial roles in cardiac survival during stress and the possible mechanisms un- derlying these effects. neonatal mouse ventricular myocytes orwhole hearts from wild-type (wt) and ncs �/� mice were subjected to stressors, and the resistance to stress was evaluated. ncs �/� mouse hearts were more susceptible to stress induced by oxidative impairment and ischemia-reperfusion injury. stress- inducedactivationofphosphatidylinositol -kinase (pi k)/akt signaling, a major survival pathway, was substantially reduced in the ncs �/�group, and overex- pressionofncs- ortheconstitutiveactive formofakt increased the survivalrate of ncs �/� myocytes. cellular atp levels, as well as mitochondrial respiration rates (both basal and maximal o consumption) were significantly depressed in ncs �/� myocytes; especially with oxidative stress. furthermore, intracellular ca þ handling was more easily dysregulated in stressed ncs �/� myocytes than wt myocytes. since ncs- levels were increased by stress, the data suggest that ncs- is a survival-promoting factor, which is upregulated by stress stimuli. interestingly, however,supra-physiological ncs- expression was toxic to cells. taken together, our data suggest that moderate ncs- expression during stress promotes cardiomyocyte survival by maintaining proper ca þ handling, which is required for activation of akt survival pathways and mitochondrial function. -pos board b initiation of electron transport activity and a decrease of oxidative stress occur simultaneously during embryonic heart development gisela beutner, george a. porter, jr. pediatrics, university of rochester medical center, rochester, ny, usa. mitochondria in early embryonic hearts are not thought to produce atp, yet they do produce reactive oxygen species (ros) that regulate myocyte differen- tiation. to assess changes in atp and ros generation in the developing heart, we measured mitochondrial oxygen consumption, the activity of the complexes (cx) and of the electron transport chain (etc), etc supercomplex assem- bly, and ros in embryonic mouse hearts. at embryonic day (e) . , mitochon- drial etc activity and oxidative phosphorylation (oxphos) are not coupled, even though the etc complexes are present. we show that cx- is able to accept electrons from the krebs cycle, but enzyme assays that specifically mea- sure electron flow to ubiquinone or cx- show no activity at this early embry- onic stage. at e . , mitochondria appear functionally more mature; etc activity and oxphos are coupled and respond to etc inhibitors. in addition, the assembly of highly efficient respiratory supercomplexes containing cx � , � , and � , ubiquinone, and cytochrome c begins at e . , the exact time when cx- becomes functional activated. at e . , etc activity and oxphos of embryonic heart mitochondria are indistinguishable from adult mitochon- dria. in contrast, generation of reactive oxygen species (ros), as measured with amplex red, is high at e . and drops significantly by e . , coinciding with activation of the etc. in summary, our data suggest that between e . and e . dramatic changes occur in the mitochondria of the embryonic heart, which result in a decrease of ros generation and an increase in oxphos due to the activation of cx- and the formation of supercomplexes. -pos board b the stoichiometry between micu and mcu determines the different mitochondrial ca d uptake phenotypes in heart and liver melanie

channel (vdac) governs the exchange of ions and metabolites between the mitochondria and the rest of the cell. in its open state vdac exhibits high conductance and selectivity for anions that facilitates the passage of adp, atp, and other metabolites. at increased voltages (> mv) vdac switches to lower conducting states, termed as ‘‘closed’’ states. closed states are cation-selective and impermeable for atp. the voltage-induced transition from the open to closed states is referred to as voltage-gating. although it is well established that vdac voltage-gating in- volves large structural rearrangements, the precise molecular mechanism of this process is still under debate. we investigated vdac voltage-gating by sys- tematically titrating vdac charge residues and by using thermodynamic and kinetic approaches to study opening and closing of the channel. all the models proposed so far agree that n-terminal region plays a key role in vdac voltage- gating. according to the original idea, the n-terminal region is a part of a mo- bile voltage sensor domain, which slides in and out of the channel lumen in re- sponse to the applied voltage. the alternative models consider independent movement of the n-terminal region upon gating. in order to test the role of vdac n-terminal region in voltage-gating, we engineered a double cys mu- tant of murine vdac that cross-links the a-helix to the b-strand of the pore wall. the cross-linked vdac reconstituted into planar lipid membranes exhibited typical voltage gating, which suggests that the n-terminal a-helix is located inside the pore of vdac in the open state and remains associated with the pore wall during voltage gating. our findings support a model where b-bar- rel is not rigid but undergoes a conformational change that leads to a partial constriction upon transition to the closed states. -pos board b novel mechanism of mitochondrial respiration control through competition between hexokinase- and tubulin for vdac binding kely l. sheldon , coert j. zuurbier , sergey m. bezrukov , tatiana k. rostovtseva . the natl. institutes of health, bethesda, md, usa, university of amsterdam, amsterdam, netherlands. the voltage dependent anion channel (vdac) is involved in regulation of me- tabolite flux across the mitochondrial outer membrane (mom). hexokinse ii (hk ) is known to bind the mom where it phosphorylates glucose into glucose- -phosphate (g p). high expression of hxk is a common phenotype of many cancers, where its concentration can be times of that in noncan- cerous cells, and is implicated in the warburg effect. it is believed that vdac serves as a hxk binding site in the mom. the amino acid n-ter- minal sequence of hxk is responsible for mitochondrial binding and, when conjugated to tat (tat-hk ), binds to mitochondria with higher affinity than native hxk , causing hxk detachment. we have previously found that dimeric tubulin reversibly binds and partially blocks vdac inhibiting me- tabolite flux across the mom. now we show that this binding can be attenuated by tat-hxk peptide as well as by full length hxk . we have found that tat-hxk and recombinant full length hxk inhibit tubulin blockage of vdac reconstituted into planar lipid bilayers without altering characteristic channel properties such as single channel conductance and selectivity. binding of hxk to vdac is verified by the generation of high-frequency excess cur- rent noise without channel closure. hxk bound to vdac prevents subse- quent tubulin binding, but only when added before tubulin, and inhibits tubulin-induced vdac blockage in a dose dependent manner. moreover, g p, which is known to cause hxk detachment from the mom, fully re- verses the inhibition of tubulin-vdac binding. this suggests that hxk de- tachment from vdac (and hence the mom) is caused by a hxk conformational change upon g p binding. thus we propose a novel mecha- nism of mitochondrial respiration control in cancer cells through the competi- tion between hxk and tubulin for vdac binding. -pos board b reprogramming of mitochondrial ca d handling in micu -deficient hela cells tünde golenár , györgy csordás

and massachusetts general hospital, boston, ma, usa. recent studies have revealed mcu as the pore forming domain and micu as a critical ca þ-sensitive regulator of the mitochondrial ca þ uniporter. how- ever, the exact role of micu in ca þ transport remains to be addressed. our previous studies showed that prolonged down-regulation of micu in hela cells (shmicu ) promotes mitochondrial ca þ uptake at low [ca þ ], which unexpectedly, fails to effectively increase matrix [ca þ ]. to determine the source of discrepancy between the mitochondrial ca þ uptake and the ma- trix [ca þ] phenotypes, first we simultaneously monitored ruthenium red- sensitive clearance of added ca þ from the cytoplasm and the corresponding matrix [ca þ] response in permeabilized shmicu cells. under conditions of similar cytoplasmic ca þ clearance, shmicu cells showed a smaller matrix [ca þ ] increase than the control, indicating enhanced buffering of ca þ in the matrix. enhanced ca þ binding in the matrix likely reflects alkalinization and enhanced phosphate transport. to test if upregulation of ca þ buffering is di- rectly linked to micu depletion, we also assessed mitochondrial ca þ han- dling after hr silencing of micu (simicu ). in simicu cells both mitochondrial ca þ uptake and the matrix [ca þ ] rise were effectively stimu- lated at low ca þ levels. thus, upregulation of matrix ca þ buffering seems to be a component of an adaptive response to sensitization of mitochondrial ca þ uptake in shmicu . the adaptive response is likely to be important to attenuate some micu -depletion induced cellular impairments that we found to manifest as attenuated mitochondrial atp production and cell proliferation. -pos board b micu -dependent threshold and cooperativity of mitochondrial ca d

boston, ma, usa. recent studies have revealed mcu as the pore forming domain and micu as a critical ca þ-sensitive regulator of the mitochondrial ca þ uniporter. how- ever, the mechanism of the complex ca þ dependence of the uniporter activity remains elusive. our previous studies showed that prolonged down-regulation of micu in hela cells causes lower threshold and decreased cooperativity of mitochondrial ca þ uptake. to study the functional significance of the effects of micu we used hepatocytes harvested from the liver of mice exposed to in vivo silencing ( weeks). silencing of micu or mcu resulted in > % decrease in their respective mrna levels. silencing of micu caused a left- ward-shifted dose response and decreased cooperativity of mitochondrial ca þ uptake in both permeabilized and intact hepatocytes. by contrast, silenc- ing of mcu resulted in slower ca þ uptake in the entire range of ca þ concen- trations without change in threshold. mitochondrial respiration and cellular atp content were unaffected in media containing both glycolytic and mito- chondrial fuels in either micu or mcu-deficient hepatocytes. however, si- lencing of micu caused an augmented loss of atp when the cells were confined to oxidative metabolism and an enhanced sensitivity to mitochondrial ca þ overload and permeabilization. during stimulation with vasopressin, a ca þ mobilizing hormone, both micu and mcu-deficient cells displayed an attenuated mitochondrial matrix [ca þ ] increase and stimulation of respira- tion. collectively, these results show that keeping the gate of mcu closed by micu at low [ca þ] is required to maintain healthy mitochondria, and micu -mediated control of mcu (cooperativity?) is required to support the propagation of short-lasting calcium spikes and oscillations to the mitochondria and the ensuing physiological stimulation of oxidative metabolism. -pos board b targeting mcl- and bak as a therapeutic tool to selectively induce apoptosis in hepaptocellualr carcinoma nima niknejad, soumya sinha roy, eric knudsen, györgy hajnóczky. thomas jefferson university, philadelphia, pa, usa. in this study we seek to identify novel drug targets to induce apoptosis in he- patocellular carcinoma (hcc) cells thus providing opportunities to develop novel treatments to improve the prognosis of liver cancer patients. several ap- optotic pathways are mediated through cleavage of bid (a bh domain-only, pro-apoptotic protein) to produce truncated bid (tbid). tbid induces apoptosis through induction of outer mitochondrial membrane (omm) permeabilization by activation of pro-apoptotic bak that resides in the omm or cytoplasmic bax. due to its localization, bak can mediate the early phase of the response to tbid. we have recently demonstrated that omm targeting of bak and the sensitivity to tbid-induced omm permeabilization is dependent on the expression of a step forward in understanding the mechanism of vdac voltage-gating

necrotizing pulmonary aspergillosis bobbak vahid md and paul e marik md we report a case of chronic necrotizing aspergillosis in a -year-old man with chronic lung disease, who was on low-dose oral prednisone. the patient was treated with various antibiotics but had no improvement. samples obtained via bronchoscopy grew aspergillus, and the patient was started on lipid formulation amphotericin b. three days after admission the patient developed fatal massive hemoptysis, presumably secondary to acquired systemic-to-pulmonary vascular communication. this is an unusual presentation of a rare manifestation of pulmonary aspergillosis. a high index of suspicion is needed to diagnose this condition in susceptible patients. key words: chronic necrotizing aspergillosis, hemoptysis, pulmonary mycosis. [respir care ; ( ): – . © daedalus en- terprises] introduction chronic necrotizing pulmonary aspergillosis was first described in by gefter et al, who described pa- tients with locally invasive pulmonary aspergillosis. gefter et al used the term “semi-invasive pulmonary aspergillo- sis” to differentiate this clinical entity from colonization of the respiratory tract and frank pulmonary invasive aspergil- losis. in , binder et al cited cases in the literature that were consistent with the diagnosis of chronic necro- tizing pulmonary aspergillosis, and coined the term “chronic necrotizing aspergillosis.” terms that were used to de- scribe cases of chronic necrotizing pulmonary aspergillo- sis before were “primary pulmonary aspergillosis,” “pulmonary aspergillosis with cavitation,” and “symptom- atic pulmonary aspergilloma.” massive hemoptysis is a rare and potentially fatal com- plication of chronic necrotizing pulmonary aspergillosis. we describe a case of chronic necrotizing pulmonary as- pergillosis that was misdiagnosed as bacterial pneumonia for several months and led to massive hemoptysis, with a fatal consequence. case summary a -year-old african american man was admitted to the hospital for dyspnea, weight loss, and chronic cough. a chest radiograph and chest computed tomogram (fig. ) showed bilateral pulmonary consolidations. review of a chest radiograph from months before this presentation revealed progression of infiltrates in the left upper and left lower lobes. no cavitary lesions were seen. the patient had been treated with several courses of various antibiotics (azithromycin, levafloxicin, and doxycycline) during the several months before this presentation, but his fever, cough, and dyspnea progressed. his medical history was notable for chronic obstructive pulmonary disease (copd), hypertension, diabetes mellitus, and gastroesophageal re- flux disease. the copd was diagnosed years before this presentation. the patient reported frequent hospital admis- sions for copd exacerbations. his last spirometry showed severe airway obstruction (forced expiratory volume in the first second . l). the patient was a smoker for years. he also reported a tuberculosis exposure in the past, but his recent skin tuberculin test was nonreactive. he also had a substantial asbestos exposure when he worked at a navy shipyard. his medications on presentation to us in- cluded metformin, lisinopril, aspirin, oral prednisone ( mg/d for about years, for copd), and an as-needed bronchodilator. bobbak vahid md and paul e marik md are

was no peripheral edema or clubbing. laboratory findings were: white-blood-cell count . � /�l, hemoglobin . g/l, and creatinine of . mg/dl. bronchoalveolar lavage fluid collected during bron- choscopy grew aspergillus fumigatus. the bronchoalveo- lar lavage fluid bacterial, viral, and mycobacterial cultures were negative. chronic necrotizing pulmonary aspergillo- sis was suspected, and the patient was started on lipid formulation amphotericin b. three days after presentation, the patient developed massive hemoptysis and died sec- ondary to respiratory failure. the lungs at autopsy showed patchy pulmonary parenchymal invasion of fungal ele- ments, with involvement of the bronchial wall, consistent with chronic necrotizing pulmonary aspergillosis (fig. ). there was no vascular invasion. although there was pleu- ral thickening and chronic inflammation, we found no as- pergillus invasion of the pleura, nor disseminated aspergil- losis in other organs. the massive hemoptysis was thought to be secondary to acquired systemic-to-pulmonary vas- cular communications seen in chronic inflammatory and infectious diseases of the lung. discussion chronic necrotizing pulmonary aspergillosis is defined as an indolent but destructive inflammatory lung infection by invasive aspergillus species (usually a. fumigatus), and is characterized by local invasion of lung tissue by fungal elements, but absence of vascular invasion. although chronic necrotizing aspergillosis is progressive over sev- eral months, there is no dissemination to other organs. , chronic necrotizing pulmonary aspergillosis is usually seen in middle-age and elderly patients. symptoms are nonspecific and include fever, cough, hemoptysis, and weight loss of – months duration. most patients with chronic necrotizing pulmonary aspergillosis have either underlying chronic lung diseases or systemic diseases that predispose them to the disease. in one study, % of pa- tients had no reported risk factors and % of patients had multiple risk factors. the pulmonary risk factors include copd, interstitial lung disease, previous mycobacterial infections, asthma, cystic fibrosis, previous lung resection, sarcoidosis, and pneumoconiosis. – the systemic risk factors are diabetes mellitus, low-dose corticosteroids, rheu- matoid arthritis, ankylosing spondylitis, and malnutri- tion. , , other rare clinical manifestations are pneumotho- rax, immune reconstitution syndrome in patients infected with human immunodeficiency virus who are on antiret- roviral therapy, pulmonary infiltrates following crypto- coccal infection, and pancoast syndrome. radiographic findings include an infiltrative process in the upper lobes or superior segment of the lower lobes, and cavitary le- sions, with adjacent pleural thickening. a mycetoma (fun- gus ball) can be seen in about % of patients with cav- itary lesions. histologic examination of the lung parenchyma shows necrotizing granulomas, invasion and destruction of lung tissue by mycetoma, or primary bron- chiolar infection. , fig. . chest computed tomogram showing bilateral infiltrates. fig. . fungal elements, showing the ° branching that is con- sistent with aspergillus species (� silver stain). chronic necrotizing pulmonary aspergillosis respiratory care • january vol no diagnosing chronic necrotizing pulmonary aspergillosis can be challenging. diagnosis may be helped by histologic evidence of tissue invasion by fungus, clinical and radio- graphic features consistent with the diagnosis, and isola- tion of aspergillus from sputum or bronchoscopic samples after exclusion of other conditions. delayed diagnosis is common and can contribute to morbidity and mortality. in one study, the average delay in diagnosis ranged from months to months. treatment options include antifun- gal therapy with amphotericin b, itraconazole, or voricon- azole. although voriconazole is equal or superior to am- photericin b for invasive aspergillosis, there are few data on chronic necrotizing aspergillosis. surgical resection is limited to a small subset of patients with local infection, adequate pulmonary reserve, and acceptable surgical risk. , chronic necrotizing pulmonary aspergillosis should be included in the differential diagnosis of pulmonary infil- trates in a patient with pulmonary or systemic risk factors and fever, cough, dyspnea, and weight loss. massive he- moptysis is a potentially fatal complication of chronic ne- crotizing pulmonary aspergillosis. references . gefter wb, weingrad tr, epstein dm, ochs rh,

castle hill hospital, academic surgical unit, hull, united kingdom purpose/objective: despite significant research input aiming to improve therapy regimens, rectal cancer remains as one of the cancers with significant morbidity rates. radiotherapy has been shown to lower -year local recurrence by approximately %. a substantial number of rectal tumours fail to respond to radiotherapy which not only presents a barrier for effective cancer treatment bu also means that those patients with therapy resistant tumours endure the harmful side effects of radiotherapy for no therapeutic gain. therefore, it is important to identify biomarkers capable of predicting a tumour's response to radiotherapy prior to treatment which can improve therapy outcomes. the aim of this study is to identify putative protein biomarkers of radiotherapy resistance using rectal cancer tissue biopsy samples by employing comparative proteomic tools. ultimate aim is to translate these biomarkers into an assay panel for routine cancer screening aiding the personalisation of cancer treatment. materials and methods: following ethical approval (sheffield rec ref /h / ), two pairs of pre-treatment rectal cancer biopsy samples (radioresistant versus radiosensitive) were investigated using antibody microarray to identify differentially expressed proteins (deps) involved in mediating radiotherapy resistance. data obtained from the experiments were subjected to data mining using ingenuity pathway analysis (ipa) which mapped these deps onto their most relevant canonical signalling pathways. results: the antibody microarray analysis of the clinical samples revealed deps and deps from the first and the second experiment, respectively. the ipa analysis of these combined generated canonical pathways. amongst these, the most interesting pathways included p signalling ( deps mapped), death receptor signalling ( deps mapped), apoptosis signalling ( deps mapped) and egf signalling ( deps mapped). radiotherapy is known to initiate cellular apoptosis via the intrinsic (mitochondrial) apoptotic pathway. however, the identification of some regulatory proteins involved in the extrinsic pathway (death receptor) apoptotic pathway (figure ) has revealed a potential link between radiotherapy and this pathway. figure : death receptor signalling a total of deps were mapped onto the death receptor signalling pathway, namely cradd, tnfrsf , mapk , tnfsf , nfkb , tnfrsf a and tnf. conclusions: antibody microarray analysis of rectal cancer biopsy samples has enabled the identification of a number of deps which may be involved in mediating response to radiotherapy. however, further confirmation with western blotting and validation with immunohistochemistry are required before such biomarkers can be introduced into routine clinical management of cancer patients. ep- validation of a rectal cancer outcome prediction model in routine chinese patients l. shen , j. van soest , j. wang , j. yu , w. hu

disappoints in colorectal cancer the combination of genentech’s atezolizumab (tecentriq) and cobi- metinib (cotellic) is no more effective than standard of care for patients with previously treated metastatic colorectal cancer, according to results presented recently at the european society for medical oncology world congress on gastrointestinal can- cer in barcelona, spain (ann oncol ; [suppl_ ; abstr lba- ]). pd-l inhibitors such as atezoli- zumab have worked poorly as a monot herapy in patients with micro- satellite-stable colorectal cancer, which accounts for % of cases. however, a study of mice with colorectal tumors found that adding a mek inhibitor, such as cobimetinib, spurs t cells to enter the tumors and boosts the effectiveness of anti–pd-l immu- notherapy (immunity ; : – ). those results led to a phase ib trial of atezolizumab plus cobimetinib in patients with metastatic colorectal cancer. building on that study, the phase iii imblaze trial assessed the drugs in patients with inoperable, locally advanced or metastatic colorectal can- cer, . % of whom had cancers that were microsatellite-stable or showed a low degree of instability. patients received atezolizumab alone, atezoli- zumab with cobimetinib, or the multi- kinase inhibitor regorafenib (stivarga; bayer), the standard of care. at the congress, researchers pre- sented data for patients, and the results revealed no statistically signifi- cant difference in effectiveness between the combination and regorafenib. the median overall survival was . months for patients treated with the two drugs, . months for those who received regorafenib, and . months for those who received atezolizumab. the overall response rates were . % in the combi- nation therapy group and . % in the atezolizumab and regorafenib mono- therapy groups. progression-free survival was also similar across the three groups. the atezolizumab/cobimetinib combination was also comparable to regorafenib in severity and frequency of side effects. the rate of grade or higher adverse effects in patients who received the two drugs was %, versus % for the regorafenib group. among the patients who received the drug duo, % developed diarrhea, % developed a rash, and % suffered nausea. in the regorafenib group, the most common side effect was hand–foot syndrome, a condition that affected % of the patients. forty-three percent of the patients in this group reported fatigue, and % suffered diarrhea. “these results are very discourag- ing,” says patrick boland, md, of roswell park comprehensive cancer center in buffalo, ny, who wasn’t con- nected to the study. given that “there is virtually no response here,” he says, “it seems doubtful that we will identify a group of patients that’s going to benefit from this combination.” however, the two drugs may still prove useful, says adam snook, phd, of thomas jefferson university in phila- delphia, pa, who also wasn’t connected to the study. the work “seems to sug- gest that pd- /pd-l signaling is not the primary cause of immune suppres- sion in colorectal cancer,” snook says. therefore, treatments that target other checkpoint proteins, such as ox , might stimulate tumors to activate pd- /pd-l signaling and become vulnerable to atezolizumab/cobimetinib therapy. “i’m excited to see what these other checkpoint pathways are going to do,” he says. –mitch leslie n cdk changes telling in prostate cancer patients with prostate cancer and specific genetic alterations may be more likely to respond to immunotherapy: in a recent study, researchers determined that men with metastatic castration- resistant prostate cancer (mcrpc) who had mutations that inactivated both cdk alleles also exhibited other genetic changes that might make them more responsive to a pd- inhibitor (cell ; : – ). “checkpoint immunotherapy in general has not done well in patients with prostate cancer” compared with melanoma and lung cancer, possibly because prostate cancer has a compar- atively low tumor mutational burden, says arul chinnaiyan, md, phd, direc- tor of the michigan center for trans- lational pathology at the university of michigan in ann arbor, and one of the study’s senior authors. in a study, chinnaiyan and others established a landscape of molecular alterations in prostate cancer by sequencing tumor biopsies from men with mcrpc (cell ; : – ). in the process, they discovered a small percentage of patients with mutations that inacti- vated both cdk alleles. to further investigate, chinnaiyan and his team performed a comprehensive genomic analysis of tumor samples from men with mcrpc. they found that % of these men had mutations that inactivated both cdk alleles, and this inactivation was associated with genomic instability, tandem duplications throughout the genome, gene fusions, and higher levels of neoantigens. the researchers also found increased t-cell infiltration in the tumors.   a related retrospective study exam- ined four patients with mcrpc who harbored cdk mutations and who did not respond to conventional treat- ments. when treated with the pd- inhibitor pembrolizumab (keytruda; merck), two experienced a decrease in psa, one of whom also demonstrated a radiographic response.    the findings suggest that such patients might benefit from pd- inhibitors, which are already approved for melanoma, lung cancer, and other malignancies, chinnaiyan says. “i think it’s building upon the idea of identify- ing various subclasses of metastatic prostate cancer that would preferen- tially respond to specific treatments—so moving towards precision medicine.” researchers will soon launch a clini- cal trial to investigate how well patients with cdk mutations respond to checkpoint inhibitors. adam dicker, md, phd, of the sid- ney kimmel medical college & cancer center at thomas jefferson univer- sity in philadelphia, pa, who was not involved in the study, considers it a “major contribution” that provides new genomic insight into prostate cancer, and could help researchers determine who may benefit from immunotherapy and why. “i think there’s a lot more we need to figure out in the realm of prostate can- cer, “dicker says,” but it’s the beginning of a road map for precision oncology, research. on april , . © american association for cancercancerdiscovery.aacrjournals.org downloaded from published

had reduced intensity regimen. there were no relapses or deaths in the allogeneic hsct group. median progression free survival (pfs) as well as median overall survival (os) in this group was months. major complications in allogeneic hsct were acute skin gvhd ( / ), cmv reactivation( / ), hhv viremia( / ), and acute renal failure ( / ) requiring short term dialysis. in the autologous hsct group, the median number of prior thera- pies was . two of patients had refractory disease prior to autologous hsct. post autologous hsct / patients relapsed and / died. major complications in this group were dvt ( / ), enterocolitis ( / ), and chf ( / ). median pfs and os were and months respectively. our patients who un- derwent autologous hsct were transplanted earlier ( / - / ) than our patients who underwent allogeneic hsct ( / - / ), leading to the difference in sur- vival times. conclusions: haploidentical hsct offers a promising cura- tive treatment for patients with mcl with expected and manageable toxicities. although a small number of patients, this review of our data provides the background for further study of the use of haploidentical hsct in this group of patients. autologous hsct for patients with mcl can also provide long term disease survival. further follow up of both groups will provide better data regarding long term (> year) outcomes. therapy for mcl in the future is likely to include newer agents (e.g. ibrutinib) in the front line, but hsct will remain a viable option. outcome of patients with multiple myeloma with t( ;

( ). senses of democracy. perception, politics and culture in latin america. austin: university of texas press. pages with a focus in latin american cultural production over the last two centuries, francine masiello has composed an extraordinary book that tells the history of what she describes as “sense work”. conceiving the evolution of the sensorium as part of political transformations and, funda- mentally, as a way of perceiving and being part of political and social changes, the author explores senses (feeling, looking, smelling, hearing) how they have changed and how they have been affected by technological transforma- tions. the combined impact of these dimensions provides a unique understanding of the region’s collective political body and its hidden mechanisms. masiello’s goals are ambitious. she puts latin american cultural production in a larger global context in which melville and paul klee might be brought into the con- versation in order to stress how specifically regional processes connected latin america with the world. the author assumes at least three simultaneous tasks in order to understand the place of the sensorium in the history of collective action: its centrality in the creation of the polity, its ambivalent relation with technological trans- formations, and the cultural production reflecting (and producing) the changes in those two realms. the intro- duction and five chapters are a journey through the inner workings of modernization. the introduction presents the book’s broad goal of analyzing the contentious and vital place of the body in politics, from the support of the mission of nations of training citizens to perceive with a shared and uniform ear and mind to the perception of violent abjection exerted against the body and to the ways in which the sensorium puts spectral presences into an intelligible perspective. though masiello’s reflection is about latin america, the focus of her exploration is mostly argentine political and intellectual life. chapter i analyzes the cen- trality of the senses in defining virtues and vices of public life and power in latin american early republican period. the works of the argentine writer esteban echeverría, his obsessive overlapping of the slaughterhouse with the political body, express how elites in the region incorpo- rated the ideas of the french ideologues, different from the rather cold approach to them by thomas jefferson in the united states. chapter ii, probably the most fas- cinating one, explores the way in which the irruption of technology challenges the sense work, but focused mostly in the way women are represented under these changes and in the way female writers revealed this conundrum. people are slaves of their eyes and ears, yet women (above all juana manuela gorriti) point out how as people develop a relation with technological advances as their new master, under which they also miss the more immedi- ate opportunity of the now. chapter iii explores the force- ful engagement with technology in the early twentieth century. horacio quiroga’s vision of “bodies of abnormal speed”, masiello sees not only the perplexity and fascina- tion with accelerated technological changes but also the reserved attitude towards an embodied knowledge that is muddling a desired form of communal life. in chapter iv, “a politics of perception”, the author dissects the penetrat- ing and prescient ideas of león rozitchner about politics, violence and the individual. as technology perfects forms of power and state oppression in the second half of the twentieth century, it also leaves exposed the bare latin american truth of the body as the locus of a prolific rela- tion between politics and violence. the last chapter and conclusion start by reflecting on the work of brazilian artist nuno ramos and his search for a sound (or lack of it) that expresses not only the deprivations of life in the sertāo, but also how technology transports those social relations over time so to become the now and here. it ends with a brief study of chilean writer diamela eltit and with how her work during the last years offers us the landscape semán, e. . masiello, francine r.

( ). senses of democracy. perception, politics and culture in latin america an electronic environment that is increasingly self-sus- taining, and where that same alienation might be the source for new creativity. according to the book’s topic, and the sophisticated exploration of the place of senses in history, the book includes magnificent and excellently reproduced plates and illustrations covering hundred years of cultural production. as technology boosts state power over social life, the body produces forms of resistance. we can read the book as an attempt to reconstruct, through the senses, the history of the masses in latin america, a study about how their irruption and the bodies, environments and preferences that make up their own sense work have been describe, dissected and also violently repressed. in the analysis of historical politics from a literary perspective, senses of democracy moves one step further from masiello’s previ- ous work about the latin american polity. and as such, it is also a valuable addition from literary studies to the vibrantly growing field of the history of the senses. for example, in history books like adamovsky and buch’s la marchita, el escudo y el bombo. una historia cultural de los emblemas del peronismo, processes that have been widely analyzed in the past reemerge under a new and vivid light as authors see how political players felt (smelled, heard and saw) masses in different and opposite perspectives. fundamental for masiello’s ideas is to locate cultural production in latin america in connection with debates and taking place elsewhere: echeverría meeting antoine destutt de tracy, xul solar departing from paul klee in the connections between nature and geometry prompted by his spiritualist calling, or rozitchner’s elaboration on fear as a human engine emerging from his work with maurice merleau-ponty. they all describe an intellectual journey that has little to do with an absorbing of european ideas and more with mapping out a dynamic intellectual field. throughout the book, the author pays attention to oscar masotta and his work on perceptions and the senses as a field of critical studies. along with rozitchner and david viñas, masotta explored the perceptual space as part of the grupo contorno and then as part of the avant- garde of the instituto di tella. a psychoanalyst himself, he wore a hearing device that he would famously switch on and off whenever he deemed necessary or convenient, both publicly and private. technology and agency allowed him to disconnect himself from hearing without losing the capacity of being able to hear. regardless of his per- sonal reasons for this, few people could have understood more clearly than him the mighty power of managing one’s own senses, whether to enhance them or to cancel them. masiello’s book is a beautiful exploration of the long history of that power in latin america. competing interests the author has no competing interests to declare. how to cite this article: semán, e. . masiello, francine r.

inhibitor triples pfs in breast cancer women with estrogen receptor (er)– positive breast cancer who took an investigational drug targeting cyclin- dependent kinases and (cdk / ) in combination with the aromatase inhibitor letrozole experienced a “dra- matic and clinically meaningful effect,” researchers reported on december at the cancer therapy and research center (ctrc) and american associa- tion for cancer research (aacr) san antonio breast cancer symposium in texas. based on the positive results, these researchers expect to launch a phase iii trial of the agent in . in the current phase ii study, patients who took pfi zer’s cdk / inhibitor pd- with letrozole (femara; novartis) achieved a progression-free survival (pfs) period of . months compared with . months for patients who were treated with letrozole alone. “this was a welcome result,” commented norman sharpless, md, deputy director of the lineberger comprehensive cancer center at the university of north caro- lina (unc) at chapel hill, who was not associated with the study. “a tripling of pfs in this disease is a great fi nding.” cdks, which participate in cell prolif- eration, tend to be overactive in cancer. richard finn, md, associate professor of medicine at the jonsson comprehensive cancer center at the university of california, los angeles, and the study’s principal investigator, explained that the primary function of cdk / is to phosphorylate the retinoblastoma (rb) protein, which ordinarily blocks early events in the cell cycle. phosphorylation inactivates rb so that cells can continue to divide. in some cancers, however, cdk / hypherphosphorylates rb, which can lead to uncontrolled cell growth. by inhibiting cdk / , pfi zer’s experi- mental drug prevents rb hyperphos- phorylation. moreover, finn added, it has minimal side effects. according to finn, preclinical stud- ies indicate that only er-positive breast cancer cells had robust responses to pd- . “er positivity appears to be a marker for an intact rb pathway,” he said. that’s noteworthy, unc’s sharp- less added, given that rb loss occurs in roughly % of all cancers. “the drug won’t work in patients who lack the rb pathway,” he noted, “so that gives us a good negative biomarker for who won’t respond to treatment. what we need now is a better posi- tive biomarker to identify those who might respond best in breast cancer and other cancer types.” ■ surveillance network aids prostate research up to % of men diagnosed with prostate cancer have a form of the disease that grows so slowly that it’s unlikely to ever threaten their health if left untreated. unfortunately, physicians currently have no precise way to determine which patients can forego treatment. “we need to fi nd out whether a tumor is a wolf in sheep’s clothing or if it’s really a sheep,” says stuart holden, md, director of cedars-sinai’s louis warschaw prostate cancer center in los angeles, ca, and medical director for the prostate cancer foundation, a philanthropic organization that funds research on the disease. thanks to a $ -million grant from the foundation, researchers from johns hopkins medicine in baltimore, md, and colleagues at cedars-sinai have launched the national proactive surveil- lance network (npsn), a repository of patient information that will advance understanding of who needs treatment. patients at the institutions who are diagnosed with early-stage, low-volume prostate cancer will be invited to join the program; other institutions will be added to the network in mid- to late . patients pursuing proactive surveil- lance defer treatments such as surgery and radiation therapy. instead, they are closely monitored with physical exams and medical tests every months and a prostate biopsy every year. if cancer progresses, they may opt for treat- ment. this strategy is also called active surveillance, expectant management, or watchful waiting. participants regularly complete detailed lifestyle and nutrition ques- tionnaires, and their blood and urine samples and biopsy tissue are banked people glenn dranoff, md, a professor of medicine at dana- farber cancer institute and harvard medical school in boston, ma, has been named the founding editor-in-chief of cancer immunology research. published by the american association for cancer research, the journal will launch online at the organiza- tion’s annual meeting in april, followed by monthly print issues beginning in june. the leader of the dana-farber/ harvard cancer center program in cancer immunology, dranoff has devoted his research efforts to under- standing tumor immunity and to the development of cancer vaccines. karen e. knudsen, phd, began a -year term as editor-in-chief of molecular cancer research this month. she succeeds michael b. kastan, md, phd, executive director of the duke cancer institute in durham, nc. knudsen is a professor in the depart- ments of cancer biology, urology, and radiation oncology at philadelphia’s thomas jefferson university and deputy director for basic science at the affili- ated kimmel cancer center. in addition to authoring book chapters and dozens of peer-reviewed articles, she has held several leadership roles on scientific publications, including cancer research. richard nakamura, phd, has been chosen as the new director of the nih’s center for scientific review (csr). he will lead scientists and administrative staff, overseeing their efforts to manage , nih grant applications a year, the majority of which are reviewed by csr peer review groups. the csr holds , review meetings a year. prior to joining the csr in , nakamura spent years at the national institute of mental health, serving as both its scientific and deputy director. c e n te r fo r s

skeletal muscle of healthy and diseased rat a wednesday, february , voltage-dependent anion channel isoform (vdac ). here, we show that hcc induced by carcinogenic compounds, aflatoxin or den is highly sensi- tized to tbid-induced omm permeabilization and cyto c release when com- pared to normal liver. expression levels of vdac and bak were also higher in hcc than in control liver. the role of the vdac -bak pathway in the differential tbid sensitivity was validated by overexpression of vdac in primary hepatocytes. in hcc cells, elevation of bak was also associated with an increased level of mcl- , an inhibitor of bak. furthermore, both constitutive and drug-induced genetic deletion of mcl- in mouse embryonic fibroblasts caused sensitization to tbid-induced omm permeabilization in the absence of a change in bcl-xl or bax . based on these results, we are evaluating the possibility of selective killing of hcc cells by the combination of a bak activator and an mcl- inhibitor. -pos board b which domain of vdac is necessary for bak insertion to the outer mitochondrial membrane and tbid - induced cytochrome c release? shamim naghdi , peter varnai , soumya sinha roy , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadlephia, pa, usa, semmelweis university, budapest, hungary. vdac proteins represent a main component of the outer mitochondrial membrane (omm). the vdac family is composed of isoforms with more than percent similarity. although their primary role was known to be in ion and metabolite transport between mitochondria and cytosol, it has been dis- covered that vdacs are also involved in apoptotic pathways. we have recently found that specifically the vdac isoform is needed for tbid-induced cyto- chrome c release, due to its role in supporting bak insertion to the omm (roy et al. . embo rep. : - ). to determine the domain(s) of vdac which supports bak insertion, vdac and vdac amino acid composition compared and the unique attributes of vdac sequencewereconsideredformutationalanalysis.totestfunctionalsig- nificance of the changes in vdac or vdac , vdac -/- mef cells that are resistant to tbid, were transfected with the mutants and insertion of bak to the omm and cytochrome c release were monitored in permeabilized cells by immunoblotting. previously, we showed that the vdac -specific n terminal tail and cysteins are dispensable for tbid-induced omm permeabilization. to approach the remaining differences four chimeras were prepared: vdac ( - )vdac ( - ), vdac ( - )vdac ( - )vdac ( - ), vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ). these studies revealed that tbid dependent omm permeabilization is only sup- ported by vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ), indicating that the first two third of vdac is required and sufficient for bak targeting to the omm and tbid induced cytochrome c release. -pos board b outer mitochondrial membrane protein distribution and function depend on mitochondrial fusion david weaver , xingguo liu , veronica eisner , peter varnai , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary. cells and tissues deficient in mitochondrial fusion have been shown to have defects linked to the exchange of inner membrane (imm) and matrix compo- nents, particularly mitochondrial dna. outer membrane (omm) constituents originate in the cytoplasm, thus the role of intermitochondrial transfer of omm components by fusion remained unexplored. here we show that fibro- blasts lacking the gtpases responsible for omm fusion, mfn / , have a more heterogeneous distribution of omm proteins than wild-type cells, and in partic- ular that heterogeneity of pro-apoptotic bak leads to dysregulation of bid- dependent apoptotic signaling. homogeneous distribution of bak is partially rescued by introduction of mfn into mfn / -/- cells. furthermore, fusions be- tween mitochondria lacking and containing bak result in hybrids sensitive to bid. proteins with different modes of omm association display varying degrees of heterogeneity in mfn / /- cells and different kinetics of transfer during fusion in fusion-competent cells. efficient coupling of omm to imm fusion depends on the presence of both mfn isoforms and is antagonized by the mitochondrial fission protein, drp . thus, omm function depends on mitochondrial fusion and is a locus of dysfunction in conditions of fusion deficiency. -pos board b mitochondrial fusion dynamics in skeletal muscle of healthy and diseased rat veronica eisner , guy lenaers , gyorgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, inserm u- , institut des neurosciences de montpellier, montpellier, france. mitochondria are highly mobile and dynamic organelles in many cell types. however, in the muscle, mitochondria are crammed into the narrow space among the myofilaments. until now, it remained unclear if mitochondrial fusion occurs in and supports the contractile activity of skeletal muscle (sm). here we applied mitochondria matrix-targeted dsred and photoactiv- able gfp to study mitochondrial fusion in rat fdb sm fibers. in vivo electro- porated fibers were imaged by confocal microscopy. when we tagged the mitochondria in ~ % of cell area with twophoton photoactivation of gfp, rapid spreading of fluorescence showed subsets of interconnected mitochondria, mostly in longitudinal direction. matrix fusion occurred with a rate of . and . events/min in adult fibers and skeletal myotubes, respectively. expres- sion of autosomal dominant optical atrophy-causing mutants of the fusion protein opa or ethanol exposure caused suppression of fusion, which is fol- lowed by mitochondrial dysfunction and late onset myopathies. when chal- lenged by repetitive tetanic stimulation, ethanol exposed cells displayed intracellular ca þ dysregulation, appearing as a fatigue pattern. ethanol also induced a decrease in mfn protein levels, without significantly altering mfn , opa or deltapsi. depletion of mfn alone was sufficient to suppress mi- tochondrial fusion in fdb fibers. fusion inhibition was apparent before any cell dysfunction, suggesting that suppression of fusion is not secondary to other problems in the cells. to directly test the role of mfn in ca þ regulation, ryr -transfected control and mfn ko mefs were stimulated with caffeine. mfn ko cells showed oscillatory ca þ transients that decayed faster than that in the control. thus, fusion dynamically connects skeletal muscle mito- chondria and serves as a target mechanism of both mutations and environmen- tal cues to cause impaired excitation-contraction coupling. -pos board b bcl-

balance between cell survival and damage signals. we focused our attention towards the intrinsic mitochondrial apoptotic pathway, where bcl- family of proteins plays the major role. we were particularly interested in two pro- apoptotic players bak and bax. here we investigated their role in apoptosis triggered by photodynamic action. we show the localization of bax and bak in u- mg human glioma cells incubated with photosensitizer hypericin (hyp) before and after photodynamic action. apoptotic stimulus by hyp photodynamic action caused bax translocation into mitochondria. however our results suggest that under these condi- tions there are two populations of mito- chondria: one which contains bax and bak simultaneously, and is almost exclu- sively localized near the plasma mem- brane; the other which contains bax only and is distributed throughout the cell. the different protein content and spatial distri- bution of these two populations suggest that they can play different roles in re- sponse to apoptotic stimuli. -pos board b stimulation of bax mitochondrial localization by bcl-xl thibaud renault , oscar teijido , gisele velours , yogesh tengarai ganesan , florent

interactions between the bcl- family proteins. an imbalance of this interaction network due to the up-regulation of the proto-oncogenes bcl- and/or bcl-xl lead to a resistance to apoptosis and is associated with tumor formation. bcl-xl overexpression act at the level of the mitochondrial outer membrane (mom) by inhibiting bax-mediated apoptosis; more particularly mac formation and cytochrome c

opening of a large non-selective channel (mito- chondrial apoptotic channel - mac) in the mitochondrial outer membrane. we used atomic force microscopy to study the structure and organization of native mitochondrial membranes isolated from necrotic and apoptotic cells. we com- plement our afm imaging with nanopatricle-based immnunoassays, where mi- tochondrial membranes are pretreated with

yi-fan lin, mei-jie jou. department of physiology and pharmacology, chang gung university, tao-yuan, taiwan. cardiolipin (cl), is a protective phospholipid located exclusively on the mito- chondrial inner membrane for stabilizing individual complex of mitochondrial respiratory chain for energy production, mitochondrial ca þ (mca þ) regula- tion and reactive oxygen spices formation. deficiency of cl has been associated with multiple mitochondrial dysfunctions upon pathological condition, diseases and aging. using fluorescence digital imaging microscopy this study investi- gated how cl is preciously regulated in rat brain astrocytes rba- . results demonstrate that at the resting stage, the distribution of cl is rather heteroge- neous within single cell. the perinulear mitochondria show lower cl than mi- tochondria from the peripheral area. heterogeneity of cl was observed even in single mitochondrion, which may affects mitochondrial fission and fusion mechanism. cl was found to be higher at the cross point area of mitochondrial network. thread-like mitochondria and granular-like mitochondria, however, contain similar level of cl. some of the thread-like mitochondria even contain lower cl than granular-like mitochondria. upon localized oxidative stress in- duced by nm laser irradiation, heterogeneous depletion of cl was observed among mitochondria populations within single cell. distribution of cl altered also mitochondrial dynamics that depletion of cl always occurred before fis- sion. intriguingly, although complete depletion of cl is irreversible upon high strength of laser irradiation, depleted cl recovered during lower strength of laser irradiation and occurred heterogeneously within mitochondria popula- tions. condensation of cl was observed upon various stresses including oxida- tive stress induced by nm laser irradiation, ionomycin-induced mca þ stress and arachidonic acid-induced lipid stress which crucially enhances pres- ervation of cl and its resistance to stress which may be of significance for mi- tochondrial protection and survival. unveiling pathophysiological regulation of cl thus may contribute significantly the prevention and treatment of cl asso- ciated pathological condition, diseases and aging. -pos board b mtdna t g mutation-induced mitochondrial complex v inhibition augments cardiolipin-dependent alterations of

tao-yuan, taiwan, national tsing hua university, tao-yuan, taiwan, chang gung university, tao-yuan, taiwan. mitochondrial dynamics including morphological fission and mitochondrial movement are essential to normal mitochondrial and cellular physiology. this study investigated how mtdna t g (narp)-induced inhibition of mito- chondrial complex v altered mitochondrial dynamics in association with a pro- tective mitochondrial phospholipid, cardiolipin (cl), as a potential therapeutic target. narp cybrids harboring % of mtdna t g genes and its parental osteosarcoma b cells were studied for comparison, and protection provided by melatonin, a potent mitochondrial protector, was explored. we demonstrate for the first time that narp mutation significantly enhances apoptotic death as a result of three distinct lethal mitochondrial apoptotic insults including oxida- tive, ca þ and lipidstress. in addition, narpsignificantly augmented patholog- ical depletion of cl. narp-augmented depletion of cl results in enhanced retardation of mitochondrial movement and fission and later swelling of mito- chondria during all insults. these results suggest thatcl is a common and crucial pathological target formitochondrial apoptoticinsults. furthermore, cl possibly plays a central role in regulating mitochondrial dynamics that are associated with narp-augmented mitochondrial pathologies. intriguingly, melatonin, by differ- entially preserving cl during various stresses (oxidation > ca þ > lipid), res- cuesdifferentially cl-altered mitochondrial dynamics and cell death (oxidation > ca þ > lipid). thus, melatonin, in addition to being a mitochondrial antioxidant to antagonize mitochondrial oxidative stress, a mitochondrial permeability tran- sition modulator to antagonize mitochondrial ca þ stress, may stabilize directly cl to prevent its oxidization and/or depletion and, therefore, it exerts great po- tential in rescuing cl-dependent mitochondrial dynamics-associated mitochon- drial pathologies for treatment of narp-induced pathologies and diseases. -pos board b shuttling of membrane-bound cytochrome b between mitochondria and er david weaver , veronica eisner , peter varnai , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis medical university, budapest, hungary. cytochrome b type b has long been described as a tail-anchored protein of the outer mitochondrial membrane (cb -mito). using a fusion protein consisting of photoactivatable gfp fused to the c-terminus membrane-targeting segment of cb -mito, we have found that while this construct concentrates in the mitochon- drial membrane, it is continuously exchanged between the membranes of the mitochondrion and the endoplasmic reticulum. this effect does not depend on the presence of mitofusin or , as it occurs in mfn-null mefs as well as in wild type cells. interestingly, a point mutation in the hydrophobic, membrane-targeting sequence of cb -mito that was recently reported to prevent its association with autophagosome membranes, also eliminates its exchange with the er. while lipids and viral proteins have been shown to traffic from er to mitochondria, this is, to our knowledge, the first demonstration of such a back-and-forth shuttling, representing both a new aspect of the er- mitochondrial interface and an mfn-independent pathway for the exchange of an outer mitochondrial membrane protein. -pos board b dichotomy between mitochondrial ca d uptake and martix [ca d] in micu deficient cells tunde golenar , gyorgy csordas , fabiana

uptake is central to cell physiology, but the underlying molecular mechanism remains elusive. recently, micu was identified as a mi- tochondrial protein required for ca þ uptake but dispensible for mitochondrial respiration or membrane potential generation. to study the specific role of micu in mitochondrial ca þ uptake, we used wild type hela cells (ctrl), micu knockdown by distinct shrnas (kd) and micu rescued cells (res- cue). first, we monitored the cytoplasmic and mitochondrial matrix [ca þ] ([ca þ]c and [ca þ]m, respectively) during store-operated ca þ entry. specif- ically, cells were preincubated in a ca þ-free buffer containing thapsigargin (tg), to deplete the er ca þ store, and then ca þ was added back and the en- suing [ca þ]c (fura ) and [ca þ]m (mitochondria-targeted pericams) changes were measured. in both ctrl and kd a [ca þ]c increase occurred that was asso- ciated with a [ca þ]m rise only in ctrl. the rescue behaved similarly to the ctrl. also, when ca þ was added to permeabilized cells, no [ca þ]m increase ap- peared in the kd. these results confirm that the shortage of micu causes sup- pression of the [ca þ]m signal. surprisingly, when the ca þ entry was followed byuncoupler additiontoreleasethemitochondrial ca þ content, ahuge[ca þ]c increase appeared in kd, however, when the uncoupler was added prior to ca þ entry, no [ca þ]c increase occurred. thus, mitochondria in the kd also accumu- lated ca þ during ca þ entry. mitochondrial ca þ uptake evoked by ca þ ad- dition was also documented in permeabilized kd by measurement of ruthenium red sensitive ca uptake and cytoplasmic ca þ clearance (fura ). thus, ca þ is accumulated by micu deficient mitochondria but it fails to result an increase in[ca þ]m.weare currentlyinvestigating, whether

earlier steps of bax- mediated apoptosis are not fully understood. we found that bax insertion into the mom was the earliest apoptotic step inhibited by bcl overexpression. paradoxically, we also found that bax translocation to the mitochondria was not inhibited but rather spontaneously increased in this same genetic context. this increase in mitochondrial associated bax required a physical interaction be- tween bax and bcl . we therefore propose that, at least when upregulated, bcl behaves as a ‘decoy receptor’ which sequestrates bax at the mitochondria but inhibits its insertion into the mom, committing the cell to survive. supported by nyu research challenge funds to ld. -pos compartmentalization of bcl family proteins mediated by organelle lipid membranes rebecca j. boohaker, ge zhang, adina loosley, kathleen nemec, annette r. khaled. university of central florida, orlando, fl, usa. cancer is defined by a pronounced inhibition of cell death. the bcl family of proteins tightly regulates the delicate balance between life and death. one method of regulation is the compartmentalization of antagonistic members. for example, bax, a pro-apoptotic member of this family, acts as the penulti- mate factor in the apoptotic cascade by releasing apoptogenic factors such as cytochrome c from the mitochondrial lumen. the normally cytosolic protein translocates from one internal compartment to another through an elusive mechanism. individual organelles are defined not only by function (mediated by specific membrane bound proteins), but by the unique composition of their phospholipid membranes. in this work, we have evaluated the contribution of organelle lipids to the localization of of bcl proteins. -pos in search of the structure of mac in the mitochondrial outer

academy of the holy names, albany, ny, usa. several groups have tried to determine the structure of the channel (mac) formed in mitochondrial outer membranes (om) of apoptotic cells or in syn- thetic membranes by bax and related proteins/peptides, using electron micros- copy (em), atomic force microscopy and x-ray diffraction. here, pore-like structures ~ - nm were handpicked from transmission em images of ura- nyl-acetate-stained oms isolated from control and apoptotic (il -deprived) fl . cells. these ‘‘candidate pores’’ were aligned by correlation procedures, and class averages defined by principal component and k-means analyses. main differences in the class averages were ( ) the presence of one or more dark (stain-filled) pores, and ( ) the nature of white (stain excluding) features around the pores. a class average consisting of a single -nm pore with pro- nounced white rim was rotationally averaged and used as a reference for cross-correlation searches of om images from control and apoptotic cells. searches using this -nm ‘‘donut’’ motif and the same motif doubled in size ( -nm ‘‘donut’’) yielded thousands of ‘‘hits’’ in both control and apoptotic membranes, which were subsequently aligned and classified as before. the pre- dominant stain-filled structures found with both motifs were not circular but elongated (up to ~ x nm), extending away from stain-excluding crescent- shaped features. the radial anisotropy ruled out reference bias and was in- consistent with pores formed by rings of evenly spaced protein subunits. we hypothesize that the different classes of structures detected represent stages in formation of mac as an increasingly large membrane bilayer defect (or ‘‘cleft’’) induced by successive aggregation or clustering of bax/bak molecules. a progressive assembly mechanism for mac has been recently suggested by real-time monitoring of mac conductances in isolated mitochondria by patch clamping (martinez-caballero et al. j biol chem : - ).

new york, ny, usa. accumulating literature associate mitochondrial dynamics with apoptosis, since regulation of either process has reciprocal effects. these processes seem to converge in formation of the mitochondrial apoptosis induced channel, mac, which releases cytochrome c and triggers the degradation phase of apo- ptosis. while bax and bak, core components of mac, were shown to interact with fusion and fission proteins, some studies also suggest proteins from the in- termembrane space could leak to the cytosol and further promote mitochondrial fission during apoptosis. the temporal relationship between apoptosis induc- tion, mac formation and mitochondrial fragmentation was investigated by time lapse microscopy. mac function was induced through staurosporine treat- ment and microinjection of tbid or cytochrome c. mac formation and mito- chondrial dynamics under these conditions were monitored in hela cells (clone ) that stably express low levels of gfp-bax and were transiently transfected with a pdsred- plasmid. gfp-bax relocation to mitochondria only during apoptosis signals mac formation, while pdsred- expression shows mito- chondrial structure as red fluorescence. treatment with staurosporine and microinjection with tbid or cytochrome c induced relocation of bax and col- lapse of the mitochondrial network. the temporal relationship between these two events was further analyzed. interestingly, pretreatment with imac , a spe- cific mac blocker, protected against cell death and prevented mitochondrial fragmentation after tbid injection. our results suggest a link exists between mac formation and collapse of the mitochondrial network during apoptosis. supported by nih grant gm . -pos mechanism of the mitochondrial cytochrome c release wave in bid-induced apoptosis soumya sinha roy, cecilia garcia-perez, erika davies, xuena lin, györgy hajnóczky. thomas jefferson university, philadelphia, pa, usa. bid, a bh -only bcl family protein, plays a central role in apoptosis. bid is cleaved by caspase- and other enzymes forming tbid that induce mitochon- drial outer membrane (omm) permeabilization and cytochrome c (cyto-c) re- lease. however a mystery remains how bid synchronizes the function of a large number of discrete organelles, particularly in mitochondria-rich liver or muscle cells. here we showed that tbid ( . - nm) elicited progressive omm perme- abilization and complete cyto-c release with a dose-dependent lag time and rate in h c cell populations. once started, the omm permeabilization was not pre- vented by tbid washout. in contrast, the dose-response for digitonin-induced omm permeabilization displayed quantal behavior. in single cell imaging studies, permeabilized h c and primary human cardiac cells transfected with cyto-c-gfp showed complete tbid-induced cyto-c-gfp release closely followed by mitochondrial depolarization. the cyto-c-gfp release started at discrete sites and propagated through the mitochondria with a constant velocity and a relatively stable kinetic of release in each organelle. similar tbid-induced cyto-c-gfp release wave was documented in intact h c cells transfected with tbid. the waves were not dependent on ca þ , caspase activation or permeabil- ity transition pore opening. however, treatment with mntmpyp, a ros scav- enger or overexpression of mitochondrial superoxide dismutase suppressed the coordinated cyto-c release and also inhibited tbid-induced cell death. on the other hand, both superoxide and hydrogen peroxide sensitized mitochondria to the tbid-induced permeabilization. thus, tbid engages a ros-dependent inter-mitochondrial signaling mechanism for spatial amplification of the apoptotic signal by mitochondrial waves. -pos role of milton domains in the calcium-dependent regulation of mito- chondrial motility sudipto das, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. the mammalian grif and oip , and the drosophila milton are kinesin- binding proteins that form a complex with the miro gtpase, an outer mitochon- drial membrane ef-hand protein, to support the movement of mitochondria along the microtubules. our study demonstrates that in h c cells overexpress- ing oip or grif , the basal motility of mitochondria is increased, whereas the sensitivity to calcium-induced movement inhibition is decreased. to dissect the interaction between milton, kinesin and miro, three different milton constructs were tested: milton ( - ), the soluble domain of milton; milton ( - ), lacking the kinesin heavy chain binding site and milton ( - ) that lacks additional ~ amino acid presumably containing part of the miro binding site. immunohistochemistry revealed that the overexpressed milton ( - ) was cytoplasmic, whereas the other two milton constructs showed mitochondrial localization. the basal mitochondrial motility was in- creased by milton ( - ) but was not altered by milton ( - ) or mil- ton ( - ). a plot of mitochondrial motility against slowly rising cytoplasmic [ca þ] induced by thapsigargin ( mm), shows that overexpression of milton ( - ) significantly reduced the calcium sensitivity of mitochondrial motil- ity reminiscent of oip and grif . by contrast, milton ( - ) or milton ( - ) did not have any effect. the thapsigargin-induced cytoplasmic calcium signal was not affected by any of the milton constructs. these data indicate that compartmentalization of bcl family proteins mediated by organelle lipid membranes in search of the structure of mac in the mitochondrial outer

university, philadelphia, pa, usa. regulation of mitochondrial motility by milton-like proteins, oip and grif grif and oip are mammalian homologs of milton, a kinesin-binding protein that forms a complex with miro gtpase, an integral outer mitochon- drial membrane ef-hand protein. kinesin, milton and miro have been proposed to function together in the movement of mitochondria along the mi- crotubules. we report here the influence of overexpression of oip and grif on mitochondrial motility and its inhibition by agonist-induced cyto- plasmic [ca þ] ([ca þ]c) signals in h c cells. ha-tagged oip and grif were overexpressed at similar level and were localized to the mito- chondria as detected by immunocytochemistry. in oip and grif overex- pressing cells, elongated mitochondria with varied degree of aggregation were visualized both in live and in fixed, immunostained samples. mitochondrial motility at resting ca þ (< nm) was greatly enhanced by oip and to a lesser extent by grif ( . . and . motility units, respec- tively against a control value of . . motility units). furthermore, the ca þ-dependent inhibition of motility during stimulation by vasopressin ( nm) was suppressed by overexpressed oip ( . . %), whereas grif ( . . %) had no significant effect compared to control ( . . %). overexpression of oip or grif did not alter either basal [ca þ]c or agonist-induced [ca þ]c levels measured by fura . collectively, these data show that both oip and grif can modulate mitochondrial motility presumably, by promoting the association of mitochondria with the motor proteins. furthermore, oip seems to have greater efficacy in the control of mitochondrial movements. -pos board b mitochondrial localization and function relationship gyorgy csordas ,

md, usa. mitochondrial contribution to cell signaling and function relies on the associ- ation and local communication of mitochondria with the er and the plasma membrane (pm). we have recently shown that the local ca þ communication between er and mitochondria is supported by interorganellar tethers, and cre- ated synthetic linkers that connected the outer mitochondrial membrane (omm) to the er and sensitized mitochondria to er ca þ release. to study the kinetics and short-term effects of the linkage formation, we have now de- vised fluorescent protein pairs targeted to the omm and er or pm containing fkbp or frb domains. rapamycin causes heterodimerization of these pro- teins to form omm-er or omm-pm bridges. confocal imaging of the induc- ible fluorescent linker pairs revealed increased association of er or pm-patches with the mitochondria within minutes of rapamycin exposure. the linkage formation between the er and mitochondria was followed by a decrease in mi- tochondrial motility (> % in min) and by sensitization of mitochondria to ip receptor-mediated ca þ release. linkage formation between pm and mitochondria also suppressed mitochondrial motility. the initial kinetics and spatial distribution of linkage formation could be followed via recording fret between cfp-and yfp-containing linker partners. a longer version of the linker was found to show faster increase of the fret signal, supporting the idea that the rate of linkage formation positively correlates with the tight- ness of the er-mitochondrial contacts. currently, we are using the fret kinet- ics to visualize the areas of close er-mitochondrial interface and study its relevance in the ca þ signal propagation to the mitochondria. thus, inducible interorganellar linkers provide a tool to assess the distance between organelles in live cells, to establish rapid changes in the subcellular distribution and dynamics of the organelles and to evaluate the ensuing changes in organellar and cell function. -pos board b bak/bax-dependent apoptotic signaling in vdac -/- cells soumya sinha roy , william j. craigen , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, baylor college of medicine, houston, tx, usa. bid, a pro-apoptotic bcl- family protein, upon activation forms truncated bid (tbid) that binds to the outer mitochondrial membrane (omm) and engages bak/bax-dependent release of cytochrome c (cyto c) and other intermembrane space proteins from mitochondria to the cytosol to induce apoptosis. the volt- age-dependent anion channel (vdac) is the major permeability pathway for metabolites and ions in the omm but its role in the tbid-induced omm perme- abilization remains controversial. previously we reported that among the vdac isoform-specific knockout mouse embryonic fibroblasts (mefs), only vdac -/- mefs lack tbid induced complete cyto c release and loss of djm. here we show by single cell fluorescence imaging that permeabilized vdac -/- mefs expressing cyto c-gfp were resistant to tbid ( nm)-induced cyto c-gfp release. furthermore, by rescuing vdac -/- mefs with vdac the tbid-induced cyto c-gfp release was restored. in addition, tbid adenovirus infection caused less cell death in intact vdac -/- mefs than in wildtype (wt) mefs. it has been reported that vdac is required for proper targeting of bak in omm. indeed, bak did not appear in the membrane fraction of vdac -/- mefs. along this line we show that permeabilized bak -/- cells were more resistant to tbid induced cyto c release and loss of djm than wt and bax-/- mefs. strikingly, washout of the cytosol further desensitized the bak-/- mefs to tbid. unlike vdac -/- mefs, the bak-/- mefs constitutively overex- pressed bax that was primarily localized in the cytosol. however, recombinant bax ( nm) could induce cyto c release and depolarization in vdac -/- mefs and also supported the tbid-induced cyto c release. thus, in vdac -/- cells bak does not localize to the mitochondria and fails to interact with tbid and does not allow a compensatory increase in bax. the combination of these two mechanisms greatly attenuates tbid-induced omm permeabilization and apoptosis. -pos board b mitochondrial fusion-fission dynamics during hypoxia/reoxygenation xingguo liu, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. structural, biochemical, and functional abnormalities of mitochondria during hypoxia/reoxygenation (h/r) are widely believed to be important pathogenic factors that underlie cell injury. however, mitochondrial fusion-fission dynam- ics responses to h/r are unclear. we investigated the effect of h/r and chem- ical hypoxia evoked by kcn on cellular atp, djm, and on mitochondrial morphology and fusion. sixty min h caused cellular atp decrease to %. djm showed progressive decrease during h, gradually improved in the first minutes r and decreased again during longer r. mitochondrial fusion activity decreased to % during h and to % during r. in addition, anomalous fusion (autofusion and fusion at multiple sites among - mitochon- dria) produced donut-shaped mitochondria during r. cyclosporine a (csa), an inhibitor of the permeability transition pore (ptp) relieved the fusion inhibition ( %) and prevented donut formation during r. five mm and mm kcn could induce cellular atp decrease to % and %, and djm decrease to % and %, respectively. depolarized mitochondria were associated with donut-formation in mm kcn, and with massive swell- ing in mm kcn. fusion activity decreased to % in mm kcn and % in mm kcn, respectively. neither h nor kcn evoked cleavage of opa , the mitochondrial inner membrane fusion protein. thus, both physical and chem- ical h induced respiratory inhibition to gradually lower djm and cellular atp level, and caused fusion inhibition that was not dependent on opa cleav- age. this is sharp contrast of the uncoupler-induced fusion inhibition that has been attributed to the rapid djm dissipation-induced opa cleavage. a conse- quence of ptp opening, the matrix swelling seems to be a key to donut forma- tion since this could be evoked by both mastoparan, a potent ptp activator and by valinomycin, a potassium ionophore. -pos board b governing respiration: tubulin’s c-terminus interaction with vdac kely l. sheldon , dan l.

bethesda, md, usa, joseph fourier university, grenoble cedex , france. mitochondria have long been known to localize within and move along the tu- bulin-microtubule network. it was shown that tubulin binds to isolated mito- chondria with high-affinity and specifically associates with the mitochondrial voltage-dependent anion channel (vdac). we found that nanomolar concen- trations of dimeric tubulin vastly increase vdac sensitivity to voltage allow- ing for vdac blockage at low transmembrane potentials. tubulin interaction with vdac requires the presence of anionic c-terminal tails (ctt) on the in- tact protein. tubulin with proteolytically cleaved ctts does not block the channel. actin, also an acidic protein but lacking ctts, does not induce vdac blockage. two synthetic peptides with the sequences of mammalian a and b brain tubulin ctt do not induce detectable channel closure up to mi- cromolar concentrations. these results suggest a completely new role for regulation of

earlier steps of bax- mediated apoptosis are not fully understood. we found that bax insertion into the mom was the earliest apoptotic step inhibited by bcl overexpression. paradoxically, we also found that bax translocation to the mitochondria was not inhibited but rather spontaneously increased in this same genetic context. this increase in mitochondrial associated bax required a physical interaction be- tween bax and bcl . we therefore propose that, at least when upregulated, bcl behaves as a ‘decoy receptor’ which sequestrates bax at the mitochondria but inhibits its insertion into the mom, committing the cell to survive. supported by nyu research challenge funds to ld. -pos compartmentalization of bcl family proteins mediated by organelle lipid membranes rebecca j. boohaker, ge zhang, adina loosley, kathleen nemec, annette r. khaled. university of central florida, orlando, fl, usa. cancer is defined by a pronounced inhibition of cell death. the bcl family of proteins tightly regulates the delicate balance between life and death. one method of regulation is the compartmentalization of antagonistic members. for example, bax, a pro-apoptotic member of this family, acts as the penulti- mate factor in the apoptotic cascade by releasing apoptogenic factors such as cytochrome c from the mitochondrial lumen. the normally cytosolic protein translocates from one internal compartment to another through an elusive mechanism. individual organelles are defined not only by function (mediated by specific membrane bound proteins), but by the unique composition of their phospholipid membranes. in this work, we have evaluated the contribution of organelle lipids to the localization of of bcl proteins. -pos in search of the structure of mac in the mitochondrial outer membrane pablo m. peixoto , christian renken , shefali haldar , carmen mannella , kathleen w. kinnally . new york university college of dentistry, new york, ny, usa, wadsworth center, albany, ny, usa, academy of the holy names, albany, ny, usa. several groups have tried to determine the structure of the channel (mac) formed in mitochondrial outer membranes (om) of apoptotic cells or in syn- thetic membranes by bax and related proteins/peptides, using electron micros- copy (em), atomic force microscopy and x-ray diffraction. here, pore-like structures ~ - nm were handpicked from transmission em images of ura- nyl-acetate-stained oms isolated from control and apoptotic (il -deprived) fl . cells. these ‘‘candidate pores’’ were aligned by correlation procedures, and class averages defined by principal component and k-means analyses. main differences in the class averages were ( ) the presence of one or more dark (stain-filled) pores, and ( ) the nature of white (stain excluding) features around the pores. a class average consisting of a single -nm pore with pro- nounced white rim was rotationally averaged and used as a reference for cross-correlation searches of om images from control and apoptotic cells. searches using this -nm ‘‘donut’’ motif and the same motif doubled in size ( -nm ‘‘donut’’) yielded thousands of ‘‘hits’’ in both control and apoptotic membranes, which were subsequently aligned and classified as before. the pre- dominant stain-filled structures found with both motifs were not circular but elongated (up to ~ x nm), extending away from stain-excluding crescent- shaped features. the radial anisotropy ruled out reference bias and was in- consistent with pores formed by rings of evenly spaced protein subunits. we hypothesize that the different classes of structures detected represent stages in formation of mac as an increasingly large membrane bilayer defect (or ‘‘cleft’’) induced by successive aggregation or clustering of bax/bak molecules. a progressive assembly mechanism for mac has been recently suggested by real-time monitoring of mac conductances in isolated mitochondria by patch clamping (martinez-caballero et al. j biol chem : - ).

new york, ny, usa. accumulating literature associate mitochondrial dynamics with apoptosis, since regulation of either process has reciprocal effects. these processes seem to converge in formation of the mitochondrial apoptosis induced channel, mac, which releases cytochrome c and triggers the degradation phase of apo- ptosis. while bax and bak, core components of mac, were shown to interact with fusion and fission proteins, some studies also suggest proteins from the in- termembrane space could leak to the cytosol and further promote mitochondrial fission during apoptosis. the temporal relationship between apoptosis induc- tion, mac formation and mitochondrial fragmentation was investigated by time lapse microscopy. mac function was induced through staurosporine treat- ment and microinjection of tbid or cytochrome c. mac formation and mito- chondrial dynamics under these conditions were monitored in hela cells (clone ) that stably express low levels of gfp-bax and were transiently transfected with a pdsred- plasmid. gfp-bax relocation to mitochondria only during apoptosis signals mac formation, while pdsred- expression shows mito- chondrial structure as red fluorescence. treatment with staurosporine and microinjection with tbid or cytochrome c induced relocation of bax and col- lapse of the mitochondrial network. the temporal relationship between these two events was further analyzed. interestingly, pretreatment with imac , a spe- cific mac blocker, protected against cell death and prevented mitochondrial fragmentation after tbid injection. our results suggest a link exists between mac formation and collapse of the mitochondrial network during apoptosis. supported by nih grant gm . -pos mechanism of the mitochondrial cytochrome c release wave in bid-induced apoptosis soumya sinha roy, cecilia garcia-perez, erika davies, xuena lin, györgy hajnóczky. thomas jefferson university, philadelphia, pa, usa. bid, a bh -only bcl family protein, plays a central role in apoptosis. bid is cleaved by caspase- and other enzymes forming tbid that induce mitochon- drial outer membrane (omm) permeabilization and cytochrome c (cyto-c) re- lease. however a mystery remains how bid synchronizes the function of a large number of discrete organelles, particularly in mitochondria-rich liver or muscle cells. here we showed that tbid ( . - nm) elicited progressive omm perme- abilization and complete cyto-c release with a dose-dependent lag time and rate in h c cell populations. once started, the omm permeabilization was not pre- vented by tbid washout. in contrast, the dose-response for digitonin-induced omm permeabilization displayed quantal behavior. in single cell imaging studies, permeabilized h c and primary human cardiac cells transfected with cyto-c-gfp showed complete tbid-induced cyto-c-gfp release closely followed by mitochondrial depolarization. the cyto-c-gfp release started at discrete sites and propagated through the mitochondria with a constant velocity and a relatively stable kinetic of release in each organelle. similar tbid-induced cyto-c-gfp release wave was documented in intact h c cells transfected with tbid. the waves were not dependent on ca þ , caspase activation or permeabil- ity transition pore opening. however, treatment with mntmpyp, a ros scav- enger or overexpression of mitochondrial superoxide dismutase suppressed the coordinated cyto-c release and also inhibited tbid-induced cell death. on the other hand, both superoxide and hydrogen peroxide sensitized mitochondria to the tbid-induced permeabilization. thus, tbid engages a ros-dependent inter-mitochondrial signaling mechanism for spatial amplification of the apoptotic signal by mitochondrial waves. -pos role of milton domains in the calcium-dependent regulation of mito- chondrial motility sudipto das, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. the mammalian grif and oip , and the drosophila milton are kinesin- binding proteins that form a complex with the miro gtpase, an outer mitochon- drial membrane ef-hand protein, to support the movement of mitochondria along the microtubules. our study demonstrates that in h c cells overexpress- ing oip or grif , the basal motility of mitochondria is increased, whereas the sensitivity to calcium-induced movement inhibition is decreased. to dissect the interaction between milton, kinesin and miro, three different milton constructs were tested: milton ( - ), the soluble domain of milton; milton ( - ), lacking the kinesin heavy chain binding site and milton ( - ) that lacks additional ~ amino acid presumably containing part of the miro binding site. immunohistochemistry revealed that the overexpressed milton ( - ) was cytoplasmic, whereas the other two milton constructs showed mitochondrial localization. the basal mitochondrial motility was in- creased by milton ( - ) but was not altered by milton ( - ) or mil- ton ( - ). a plot of mitochondrial motility against slowly rising cytoplasmic [ca þ] induced by thapsigargin ( mm), shows that overexpression of milton ( - ) significantly reduced the calcium sensitivity of mitochondrial motil- ity reminiscent of oip and grif . by contrast, milton ( - ) or milton ( - ) did not have any effect. the thapsigargin-induced cytoplasmic calcium signal was not affected by any of the milton constructs. these data indicate that compartmentalization of bcl family proteins mediated by organelle lipid membranes in search of the structure of mac in the mitochondrial outer

integrative medicine at jefferson university hos- pitals, thomas jefferson university, philadelphia, pennsylvania, has com- bined its expertise, expe- rience, and advanced diagnostics to serve as a leader in the field of inte- grative medicine and provide state-of-the-art care for people desiring an integrative medicine approach to their health. now, the recent award- ing of a $ million grant by the marcus founda- tion, inc., has allowed for the establishment of a new center, the brind-marcus center of integrative medicine, in villanova, pennsylvania, which opened its doors in december . the new center has enabled expansion of both clinical and research endeavors as well as cutting-edge technology, including the addition of a unique positron emis- sion tomography–magnetic resonance imaging (pet-mri) scanner. daniel a. monti, md, mba, senior vice president and the director of both centers, commented on the evolution of success of integrative medicine at thomas jefferson university: there has been a real transformation over the past decade at jefferson, where integrative medicine is now definitely part of the fabric of the enterprise and a highly featured and well-positioned department in the institution. each integrative medicine center throughout the country may be very different in terms of clinical and research offer- ings. our approach is to look through the lens of modern medicine within a holistic framework and serve as a consultation service for all. now, through the generosity of the marcus foundation, we have expanded our current capabilities with a broader geographic reach to provide expertise in therapeutic options beyond conventional medicine, such as targeted nutrition, lifestyle change, and advanced diagnostic technology. we could not be more excited about this. kathleen gallagher, executive vice president, chief oper- ating officer, and chief corporate officer of thomas jefferson university commented: “our integrative medicine initiative has been a very successful program, with excellent patient feedback, and now the demographics of having a center in a suburban setting provides more access to individuals who are looking for this type of care.” she added: “our institution fully supports the presence and expansion of integrative medicine within our centers, and we are pleased to be able to provide board-certified physicians and expert clinicians to approach our programs and expansion from an evidence-based and sci- entifically sound foundation.” expansion of services and cutting-edge technology the new , -square-feet brind-marcus center of in- tegrative medicine in villanova, pa, represents a major ex- pansion of integrative health services at jefferson, which builds upon the successful model created by their philadelphia facility, the myrna brind center of integrative medicine. the brind-marcus center of integrative medicine will provide new as well as similar services as the main campus including: one- on-one consultations with integrative medicine experts; ex- tensive integrative medicine programming; advanced diag- nostics capabilities with the new pet-mri scanner; and an infusion center. dr. monti commented: “we provide a very careful and thoughtful assessment with the patients we see, which is comprehensive and offers a lot of one-on-one physi- cian time. however, in addition to a thorough head-to-toe assessment, we also spend considerable time on stress daniel a. monti, md, mba, senior vice president and director of jef- ferson’s myrna brind center of in- tegrative medicine and brind-marcus center of integrative medicine. alternative and complementary therapies doi: . /act. . .mbr � mary ann liebert, inc. � vol. no. april management, daily intake of nutrients, and other important lifestyle variables.” featuring holistic medical and wellness services, the depth and breadth of program offerings at both the center city philadelphia and villanova centers is significant and includes: an integrative executive health program; integrative chronic illness management; integrative cardiology; a neurocognitive (executive brain health) program; micronutrient infusion therapies; natural hormone therapies; acupuncture; a smoking cessation program; a wide range of mindfulness-based stress reduction (mbsr) programs; and others. sabrina bazzan, jd, mba, administrative and operations director at the myrna brind center and at the brind-marcus center of integrative medicine stated: “our executive health program—executive great life—is a key service that is of- fered at both locations and is one of the only executive health programs in the nation that is rooted in integrative medicine.” dr. monti added: “we have an increasing number of compa- nies signing on to have their executive team[s] receive yearly physicals through this program. this has been a stand-alone service that has done very well and has raised awareness about our center and generated many referrals as well.” the mbsr program, another flagship program, is one of the largest in the country, according to dr. monti, with the ability to certify trainers in mbsr. he states: “we have a great breadth of curriculum in mindfulness that has been a core part of the center, from offering the -week standardized program, to certifying teachers, to specialized programs for mental health professionals, as well as workshops that we offer to medical students and other professionals.” advanced diagnostic technology one of the main features of the brind-marcus center of integrative medicine is the new pet-mri scanner which was also funded through the marcus foundation grant. dr. monti stated that the pet-mri scanner at the villanova center is the first in the region, making it a distinguishing feature not only for integrative medicine at thomas jefferson university, but also for the entire institution. dr. monti explained: the pet-mri scanner allows us to do pet imaging with mri instead of a [computed tomography] scan, and there are a lot of advantages to this. if we are looking at the brain, for example, we can obtain a picture of anatomy with the mri and also get a sense of functional activity with the functional mri. in addition, we can view yet another layer of functional activity with the pet scan, all in one hybrid, integrated machine without ever leaving the room. vijay m. rao, md, facr, david c. levin professor and chair, department of radiology, sidney kimmel medical college at thomas jefferson university, commented: “our new offering of the pet-mri, the latest advancement in imaging technology, furthers our commitment to innovation and an integrative approach to patient care. the pet-mri the brind-marcus center of integrative medicine, in villanova, pennsylvania. mary ann liebert, inc. � vol. no. alternative and complementary therapies � april allows a unique view of both anatomy and metabolic activity, providing a more complete investigation into our patients’ conditions. this capability increases patient access to cutting- edge technology, and the information that a pet-mri provides can also help close the gap between diagnosis and treatment.” andrew b. newberg, md, professor of emergency medi- cine and radiology and director of research at both centers commented on the new technology: “clinically, the pet- mri scanner will help us to better evaluate patients in order to determine more effective therapeutic approaches for many of the conditions we treat.” he added: “by using the pet-mri scanner, we can obtain detailed diagnostic information to help guide therapy for conditions such as chronic fatigue, chronic pain, irritable bowel syndrome, cognitive impairment or cardiovascular risk. from a research perspective, the pet- mri will truly be a game changer in terms of helping to better understand the physiological effects of integrative therapies.” dr. newberg and his colleagues are planning an aggressive research program, which will use the pet-mri scanner to help determine, for example, how proper diet and nutrition reduce inflammation; how specific supplements might im- prove cognitive function or help patients who have neuro- degenerative disorders such as parkinson’s disease; and how practices, such as meditation, acupuncture, or other mind– body approaches, work to improve patients’ health and well being. he said: “the ability to demonstrate the specific mechanisms by which these integrative approaches work will provide the necessary data to potentially shift medical atti- tudes about integrative medicine.” the brind-marcus center of integrative health will also offer a neurocognitive assessment service (executive brain health), where the technology of the pet-mri is combined with neu- rocognitive testing, autonomic nervous system testing, and a neurological examination. bazzan said, “i am very excited about our new executive brain health program, which will utilize this technology and provide the most comprehensive assessment of cognitive function and brain health available.” in terms of how these services will specifically benefit patients, dr. monti commented: “one of our goals, for example, is that if a personisrelativelyhealthy,buttheywanttomaximizecognitive reserve, then we will take an integrative approach for the path forward, utilizing a range of options from diet and targeted nutrition to stress-reduction and brain-fitness programs.” for patients with postconcussive symptoms, the pet-mri can help document areas of the brain that are abnormal in their function and then help tailor a treatment program—including diet, supplements, meditation, or other integrative approaches designed to help support brain function—according to dr. newberg. he commented: “the opportunities with the pet- andrew b. newberg, md, reviews a pet-mri scan. positron emission tomography–magnetic resonance imaging scan- ner at

every disorder we treat can be evaluated using the pet-mri scanner. it will help us to better understand the underlying path- ophysiology of diseases and show how integrative medicine ap- proaches can help reduce or eliminate the effects of these diseases and improve the physical and mental health of our patients.” collaboration key to success collaboration has been critical for the success of the myrna brind center of integrative medicine and the establishment of the new brind-marcus center of integrative medicine. dr. monti stated: “it has been so important to collaborate whenever there is an opportunity to partner with other de- partments and institutions and to grow and learn as we go. this spirit of collaboration, i believe, is one of the factors that the marcus foundation found appealing about our approach. we have built a relationship with the marcus foundation over the past several years, and our current endeavor builds upon previous successes we have had with them, as well as other external funders.” he added, “bernie marcus is a great visionary who has served the local, national and even inter- national community.” initially, the myrna brind center of integrative medicine partnered with the marcus foundation on a phase trial ex- ploring the use of high-dose intravenous vitamin c with pa- tients who had pancreatic cancer. collaboration then continued around a discussion about advancing the integrative medicine model and the potential value of a second integrative medicine site. “we are starting to see the fruits of our labor across several initiatives, and having the marcus foundation as a partner is tremendous,” dr. monti said. other important elements for success in building and ex- panding the integrative medicine model have included: a pio- neering spirit; testing therapies to prove efficacy; and initiating novel endeavors, such as exploring the use of micronutrients as supportive therapies for patients. “novel endeavors such as these have raised awareness of the kind of work that we are doing here and sends a message to both patients and clinical partners that we are willing to explore whatever is necessary to help patients who are in difficult positions,” dr. monti said. conclusion in the spirit of collaboration, dr. monti stated that the structure of integrative medicine provided at the two centers is serving as a national model to help other clinicians and insti- tutions foster their own integrative medicine programming. dr. monti commented: i, along with other clinical leaders here at jefferson, am constantly involved with national meetings and symposia where we encounter people from both academic health and private centers who are trying to figure out what steps to take next and how to expand their integrative medicine models. we also publish in both the academic and lay press so that we can share what we are learning with other people in the field. people are eager to come and see what we are doing here and want to understand how to take their centers to the next level. we like being able to share that with people and will continue to serve as a model. dr. monti concluded: “our goal is to extend the bounds of good medicine, and i think that we are continually achieving that here at our centers. our biggest job now is to avoid be- coming complacent with these successes and to keep pushing the envelope for the next series of advances.” jane hart, md, is a clinical instructor in internal medicine at case western reserve university school of medicine, in cleveland, ohio. about the centers the myrna brind

). only about % of people with phds in the biologic sciences hold tenure- track jobs within to years of earning their doctoral degrees, whereas fewer than % of them work in industry, she says. no national data track the careers of individuals with mds, but the “general thought is that a paucity of physician–scien- tists inhibits the advancement of research into clinical applica- tions,” says carrie wolinetz, phd, associate vice president for federal relations at the association of american universities. in spring , nih director francis collins formed a work- ing group to examine the future of the biomedical research workforce to address the positions and support needed for suc- cessful careers that will advance science and promote health. “openly talking about this is new,” comments cynthia fuhrmann, phd, program director for academic career development and assistant professor in biochemistry and biophysics at ucsf. “national policy makers at nih might be able to create a more open dialogue about career choices and place a stronger emphasis on career development in the training of phd-level scientists.” staying flexible for research young scientists “need to be thinking about career tracks, not just research directions,” advises jonathan wiest, phd, director of the national cancer institute’s center for cancer training. given the hundreds of charitable organizations and in- stitutions devoted to cancer research, scientists may have more opportunities in cancer than other fields, observes bert vogelstein, md, ludwig professor of oncology at johns hopkins university and a howard hughes medical institute (hhmi) investigator. even so, postdocs these days may spend an extra year or trying to find the right job. jobs wanted: cancer research vogelstein advises graduate students aiming for a research career to choose a postdoctoral fellowship in a different field, such as switching from biochemistry to genetics or from proteomics to microfabrication. scientific success depends in part upon creativity, “making connections between things that haven’t been connected before,” remarks vogelstein. “in order to connect ideas or experimental approaches, one has to know things.” marja nevalainen, md, phd, extends that advice to mul- tidisciplinary experience. “typically, postdoctoral training is overseen by one mentor,” says nevalainen, an associate professor of cancer biology, medical oncology, and urology, who also oversees junior faculty and graduate education at thomas jefferson university’s kimmel cancer center in philadelphia. nevalainen suggests an advisory committee of or members for each postdoctoral trainee. “if you have a strong basic scientist as one mentor, input from a physician– scientist may facilitate thinking about research designs in the lab that have translational applications,” she adds. experts emphasize that phds and mds also must keep an eye out for growing areas of research. for instance, james broach, phd, professor of molecular biology at princeton and president of the cancer biology training consortium, recommends pro- ficiency in genomic tools and potential clinical applications, such as understanding the genetic dynamics of a particular tu- mor at the same time it is being treated. craig thompson, md, president and ceo of memorial sloan-kettering cancer center in new york, suggests delving into the strong computational approach of systems biology to understand networks within and between tumor cells. “the system is changing,” sums up howard garrison, phd, public affairs director for the federation of american societies for experimental biology. “no one is sure where the funding will come from to do it all or how to prioritize the way it gets done, but there will be opportunities for very talented people who are excited about the science.” — carol cruzan morton ■ the population of college students interested in careers in health and biologic sciences continues to climb, although those who want to do research face an increasingly tight job market. so ur ce : c ou nc il of g ra du at e sc ho ol s research. on april , . © american association for cancercancerdiscovery.aacrjournals.org downloaded from published onlinefirst december , ;

http://cancerdiscovery.aacrjournals.org/ © macmillan magazines ltd the thomas jefferson paternity case the dna analysis of y-chromosome haplo- types used by foster et al. to evaluate thomas jefferson’s alleged paternity of eston hemings jefferson, the last child of his slave sally hemings, is impressive. how- ever, the authors did not consider all the data at hand in interpreting their results. no mention was made of thomas jeffer- son’s brother randolph ( – ), or of his five sons , . sons of sally hemings con- ceived by randolph (or by one of his sons) would produce a y-chromosome analysis identical to that described by foster et al. further collaborative data (for example, the whereabouts of any of those who might have been involved at conception) are needed to confirm that jefferson did indeed father his slave’s last child, as claimed in the title. we know thomas jefferson was there, but how about randolph jefferson and his sons? david m. abbey health science center, university of colorado, teakwood court, fort collins, colorado , usa e-mail: dabbey @aol.com if the data of foster et al. are accurate, then any male ancestor in thomas jefferson’s line, white or black, could have fathered eston hemings. plantations were inbred communities, and the mixing of racial types was probably common. as slave families were passed as property to the owner’s off- spring along with land and other property, it is possible that thomas jefferson’s father, grandfather or paternal uncles fathered a male slave whose line later impregnated another slave, in this case sally hemings. sally herself was a light mulatto, known even at that time to be thomas jefferson’s wife’s half sister , . gary davis evanston hospital, ridge avenue, evanston, illinois , usa foster et al. reply — it is true that men of randolph jefferson’s family could have fathered sally hemings’ later children. space constraints prevented us from expanding on alternative interpretations of our dna analysis, including the interesting one proposed by davis. the title assigned to our study was misleading in that it repre- sented only the simplest explanation of our molecular findings: namely, that thomas jefferson, rather than one of the carr broth- ers, was likely to have been the father of eston hemings jefferson. it had been suggested to us earlier (by herbert barger, who also helped to recruit the descendants of field jefferson who par- ticipated in our study) that isham jefferson, son of thomas jefferson’s brother ran- dolph, might have been the father of one or more of sally hemings’ children. barger’s proposal was based on a statement that isham was reared by thomas jefferson; he suggested that isham could have been at monticello or at snowden (snowden was across the james river from scottsville, which is about miles from monticello) when eston hemings was conceived. but it is not known for certain that isham was at monticello at that time, whereas it is docu- mented that thomas jefferson was. from the historical knowledge we have, we can- not conclude that isham, or any other member of the jefferson family, was as likely as thomas jefferson to have fathered eston hemings. we know from the historical and the dna data that thomas jefferson can neither be definitely excluded nor solely implicated in the paternity of illegitimate children with his slave sally hemings. when we embarked on this study, we knew that the results could not be conclusive, but we hoped to obtain some objective data that would tilt the weight of evidence in one direction or another. we think we have provided such data and that the modest, probabilistic interpretations we have made are tenable at present. e. a. foster*, m. a. jobling†, p. g. taylor†, p.

the same body size and aero- bic power. volume densities of mitochon- dria in leg muscles are similar to those of mammals of the same size and aerobic capacity, whereas those in the relatively inactive flight muscles are only half as large and correspond to values reported for less aerobic mammals (table ). given that % of the rhea’s body mass consists of leg musculature, rates of oxygen uptake by mitochondria per millilitre dur- ing locomotion at the aerobic maximum appear to fall within the range reported for mammals. capillary densities in the rhea leg and flight muscles, like the mitochon- drial volume densities, also parallel values reported for the muscles of athletic and less mobile mammals. in contrast to the apparent conservation of structure–function relationships in most of the respiratory system, our results sug- gest that there are basic differences in the performance of the lungs of birds and mammals. we could not measure the lung volumes of the rheas directly, but in birds these are normally slightly more than half of those of mammals of the same mass , . the rheas therefore achieved maximum oxygen flux rates, equal to those of the most aerobic mammals of their size, using lungs that are probably only half as large. this supports the general belief that avian lungs provide relatively more function per unit volume than mammalian lungs , . although the aerobic limits of rheas and athletic mammals are similar, the metabolic power available in practice, and their func- tional needs, are not. unlike dogs, horses and other athletic mammals that sustain high metabolic rates for hours during pre- dation and migration, rheas do little or no sustained running and are poor at dissipat- ing metabolic heat loads . rheas have apparently not been under strong selective pressures like those that promoted the aero- bic power of extant running mammals. large flightless birds lead fairly inactive lives, and may have lost the ability to fly primarily because of a lack of predation. why rheas have an aerobic power that greatly exceeds their apparent functional needs remains a puzzle. matthew w. bundle*, hans hoppeler†, ruth vock†, june m.

" to this jefferson sent a very characteristic reply. he named over the several works he supposed campbell had in mind. the notes on virginia, jefferson said, he planned to revise and enlarge, but the work of revision could not be undertaken now. the summary view "was not writ- ten for publication" in the first place: i do not mention the parliamentary manual published for the use of the senate of the u. s. because it was a mere compilation, into which nothing entered of my own, but the arrangement, and a few observations necessary to explain that and some of the cases. i do not know whether your view extends to official papers of mine which have been published. many of these would be like old newspapers, materials for future historians, but no longer interesting to the readers of the day. they would consist of reports, correspondencies, messages, answers to addresses; a few of my reports while secretary of state might perhaps be read by some as essays on abstract subjects. such as the report on measures weights &c coins, on the mint, on the fisheries, on commerce, on the use of distilled sea-water &c. the correspondencies with the british & french ministers, hammond and genet, were published by congress. the messages to congress, which might have been interesting at the moment, would scarcely be read a second time, and answers to addresses are hardly read a first time. so that on a review of these various materials, i see nothing encouraging a apaper read at chapel hill, n. c, october , , at the joint annual meeting of the society of american archivists and the american association for state and local history. d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u niversity user on a pril t h e a m e r i c a n a r c h i v i s t printer to a republication of them. they would probably be bought by those only who are in the habit of preserving state-papers, & who are not many. i say nothing of numerous draughts of reports, resolutions, declarations &c. drawn as a member of congress or of the legislature of virginia, such as the declaration of independance, report on the money unit of the u. s., the act for religious freedom &c. &c. these having become the acts of public bodies, there can be no personal claim to them, and they would no more find readers now than the journals & statute books in which they are deposited. i have presented this general view of the subjects which might have been within the scope of your contemplation, that they might be correctly estimated before any final decision. they belong mostly to a class of papers not calculated for popular reading, & not likely therefore to offer profit, or even indem- nification to the republisher. submitting it to your consideration i tender you my salutations & respects. negotiations went a little further but were then dropped. evi- dently jefferson, though perfectly cooperative, brought campbell round to his own view of the matter. he would willingly have seen a collection of historical records published, for he presumed there were some others besides himself interested in acquiring such rec- ords ; but he could not recommend the proposal as a money-maker, and he said so frankly. campbell's plan for an octavo volume of jefferson's writings was the first attempt at what we are hoping to do in fifty rather larger volumes. it is pleasant, if not particularly rewarding, to speculate on what jefferson would have thought of our undertaking to gather and print all of his papers. he would, i know, have been surprised. he would not, i think, have been irritated or distressed. there is abundant evidence to show that he expected to have his papers studied and used by scholars. no other president except the sec- ond roosevelt has possessed so strong an archival instinct; and however badly his papers have been manhandled since, jefferson himself left them in beautiful order. if he had had anything to keep secret, he could and presumably would have destroyed it; yet there is no evidence that he ever destroyed a scrap of paper except his correspondence with his wife. that belonged to him, but every- thing else was preserved for the public to scrutinize in the future with all the curiosity that it wished. in the princeton file there are literally hundreds of scraps of paper saved by jefferson, and among them are some of the most entertaining and occasionally significant pieces in the whole body of his archives. there are mathematical calculations; designs for machines and furniture and landscape details; recipes for macaroni and other dishes; itineraries; agricul- d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u niversity user on a pril t h e papers of thomas jefferson tural and meteorological d a t a ; tables of useful information; book lists; and notes and memoranda on an incredible variety of subjects, from the use of archimedes' screw at kew to snuff, sophocles, and specific gravity. these may be trivia; nevertheless, we owe the re- cent recovery of a fragment of the earliest text of the declaration of independence to jefferson's habit of not throwing away any- thing he had written. or, to take a less spectacular yet important and characteristic instance of his archival habits, i may mention a dossier recently found, just as jefferson left it, of material relating to his tour in the low countries and up the rhine in the spring of . t h e r e are over fifty separate pieces in the group, includ- ing a record of daily expenditures, itineraries and advice on travel conditions, a colorful group of printed and engraved tradecards from inns and shops in the towns where he stopped, and receipted bills (in four languages) for lodging, meals, coach-hire, and pur- chases along the way. dipping into the collection is as effective a means as i know of reconstructing the life of the roads and hostel- ries of x century and a half ago. t h e jefferson archives contain masses of material of this kind — social documentation, if it is to be given a colorless name. jeffer- son would have been happy to see it put to use, however surprised he would have been to learn that his papers constitute an encyclo- pedia of his times. though i am among those who find jefferson's words unfail- ingly interesting and frequently inspiring, this is a technical rather than an inspirational paper. i shall therefore pass over the early history of the enterprise: how it grew out of m r . julian p. boyd's work as historian of the jefferson bicentennial commission in ; how t h e n e w york times co., seeking an appropriate me- morial for the late adolph s. ochs, agreed to finance the editorial operations; and how the princeton university press undertook to publish the work in an estimated fifty volumes. i propose here to present a report of progress thus far, and to treat in some detail of the three major phases of the w o r k : gathering the materials, processing them, and getting them into print. ii the plan mr. boyd set forth in his report to the bicentennial commission called for the assembling of the entire jefferson docu- mentation in photofacsimile form; and the agreement with the new york times co. called for the publication of all of the papers assembled (some, to be sure, in only summary form). these two d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u niversity user on a pril the american archivist decisions placed the work on a different footing from any previous undertaking. it was to be a new and in some respects a unique com- bination of archival and editorial aims and functions. the work could not have been undertaken at all, of course, with- out the aid of the microfilm camera — an instrument which makes us all equal, in a way, with peter force or lyman draper. of al- most equal importance to us has been the continuous-process en- largement printer, familiar to everyone as the v-mail machine, which enabled us to obtain paper prints of the documents in the larger collections at a very low cost per page. in addition to econo- my, the use of photofacsimiles has certain other solid advantages. in the several editorial processes, one cannot handle an autograph document years old with the freedom one can handle a print of it. the reproduction can be cut up and distributed by date if nec- essary, as in the case of letterbooks or in the many cases we have encountered of jefferson's using a single piece of writing paper for several purposes. a reproduction can be stamped for control pur- poses; marginal notes or readings can be placed on it. and so on. at the same time dependence on photoreproductions has some grave disadvantages. in any given , microframes made from mounted or loose mss., one can always count on a few accidental omissions. when blank pages are not filmed, endorsements and docketing memoranda of consequence are sometimes overlooked, and perplexities and doubtless errors sometimes result in attempting to reconstruct the original document. reading from poor prints, or prints made from defective originals, can be among the most ex- asperating experiences of editorial life. one is forever straining to discover what was in the inner margin into which the camera did not reach, or in the outer margin obscured by the mounting sheet. for these and other reasons we are obliged, as we transcribe and edit, to bombard the custodians of the originals with queries that must tax even their notorious patience. the second decision mentioned above — that the edition was to comprehend the entire body of jefferson's papers — differenti- ated the undertaking from others of its kind in one very obvious respect: it was to be much larger than any similar publication. i t is not possible, even if it were worthwhile, to compare statistically the total bulk of the jefferson archives with the archives of other highly productive public men; but it is doubtful whether, before the advent of the typewriter, any other public figure left as many papers. franklin lived as long and had almost as wide-ranging in- d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u niversity user on a pril t h e papers of thomas jefferson terests, but he was never president. washington was president and, what is more, commander-in-chief for eight years, but his interests were narrower and his life considerably shorter. in any event, there has been no attempt at either a comprehensive franklin or a com- prehensive washington: we have only one side of their respective correspondences in print. t h e bicentennial washington, it may be pointed out, though running to thirty-seven volumes of text, con- tains only about one third the number of words ( , , ) and about one third the number of documents ( , ) that the jeffer- son is planned to embrace in fifty volumes of text. o r if we com- p a r e the jefferson with the enterprise most nearly like it in editorial form, the yale edition of h o r a c e walpole's correspondence, we find that, though the walpole is to be completed in fifty noble vol- umes, only about one quarter as many documents are being included in each of its volumes as are planned for each volume of the jeffer- son. in his introduction to young washington, mr. freeman ob- serves that "nearly as much of the life of a man is set down in the letters addressed to him as in those written by him." with jefferson this is not only true in general, but in some correspondences the in- letters are of greater value than jefferson's own. examples are his exchange of letters wih eli whitney on the cotton gin in , his exchange with d. b. lee on transportation by air in , and, still more strikingly, in his correspondence with gen. william clark in on fossil excavations at the big bone lick. jefferson had a really boyish enthusiasm for fossils. in the fall of , at his own expense, he engaged clark to conduct a thorough search of the fossil area at big bone lick in kentucky. the bones clark dug up and shipped — some — were divided between the american philosophical society and the museum d'histoire na- turelle in paris, the latter group forming the basis of baron cu- vier's fundamental studies in paleontology. the big bone lick excavations and jefferson's part in the founding of paleontological science have been exhaustively written about, but none of the learned historians of the science have, apparently, looked through the letters jefferson received. if they had, they would have come upon a twelve-page letter clark wrote to jefferson from louis- ville on nov. . this, in the opinion of experts, is one of the best reports on early paleontological research that survives, and it is at the same time, in the opinion of anyone who can read, a wonderfully entertaining document. when one begins to quote d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u niversity user on a pril t h e american archivist from it, one cannot stop, and so i must forbear altogether. i t goes without saying that letters of this caliber we plan to publish entire. but a great many of the in-letters, particularly those of a routine nature, will be summarized. t h e availability of a letter elsewhere in print will influence our decisions on this point. t h e location of the m s . and of printed texts, if any are available, will of course always be given for the documents summarized. t h e operation of gathering the materials to reconstruct the jef- ferson archives began with certain obvious steps. t h e main mass of jefferson's "official papers" (the term is a very loose one) be- came the property of the united states in and, since the be- ginning of this century, has been in the custody of the library of congress. in the library was in the process of recataloguing and microfilming its jefferson collection and was gathering in, as well, microcopies of other major jefferson collections. w e became the library's collaborators in the latter operation, and by the be- ginning of had received and processed prints of some , jefferson documents in the l.c., the massachusetts historical so- ciety, and the historical society of pennsylvania; during about , further documents were added from several large virginia repositories, the new-york historical society, the amer- ican philosophical society, the huntington library, the new york public, and the pierpont morgan libraries. in and the large holdings of the missouri state historical society, the vir- ginia state library (a second crop), and several large private re- positories were rounded up. a systematic search at t h e national archives was begun before the end of but was interrupted and has not yet been completed. soon after our operations started, the inflow of material from smaller repositories and private col- lections began. though at times it has shrunk to a trickle, it has never dried up. nearly eighty documents a month were accessioned during . w e have done everything we could within reason — and some- times perhaps without much reason, though with definite advan- tages — to stimulate and maintain the flow. in a sense we have been concerned more, as in the scriptural story, with the fugitive one than with the dutiful ninety-nine. a case in point is the mission to the otoe indian reservation in to obtain a photostat of one of jefferson's addresses to a delegation of indian chiefs. this was the only such paper known to survive in the custody of any tribe that had received messages from jefferson, and so was of some d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u niversity user on a pril •*. < • * * *•>.-"". •• ~ ..-:, ? a'mt^n ' '^"'^ - ., * , . - -̂ j " - y ' - " .

the tribe. like conrad weiser or sir william johnson in another age, we found it worthwhile to subscribe to the indians' deep sense of protocol. and i may add that, upon our return to our desks, we found that a dozen or so other jefferson documents had emerged from their hiding places as a result of the publicity attendant on our otoe mission. besides publicity, both grave and gay, we have sent out many hundreds of direct-mail appeals to likely quarters — to librarians, patriotic societies, dealers, collectors, descendants of jefferson and of his correspondents. leads have come from all directions, and we have chased many a will-o-the-wisp with as much vigor as if it were a bundle of love letters exchanged by thomas jefferson and martha wayles skelton. friends of jefferson and friends of ours, some of whom never become known to us by name, prod others who own jefferson autographs to send us photostats. they also write us about jeffersonian utterances and allusions in out-of-the-way printed sources: in the minneapolis journal for february ; in a german broadside found in the hessian archives in marburg; in abolitionist periodicals and pamphlets; in travel books; and so on. we welcome information of this kind with the warmest feelings of gratitude. a fifty-first volume may have to be devoted to ac- knowledgments to our many collaborators, but the preceding fifty will be immeasurably richer for their efforts. printed bibliographies, guides (such as the carnegie series on foreign archives), catalogues of manuscript collections, bookseller's catalogues, and auction records have likewise furnished grist to our mill. the jefferson checklist at the university of virginia, an annotated card catalogue of both published and unpublished writ- ings, has proved inestimably helpful. everyone who has worked with jefferson knows of the unique aid he himself left in the form of a register of all his correspondence. this "epistolary record" becomes reliable at the time jefferson succeeded franklin as our minister in france and continues in an unbroken series of entries until ten days before he died. the period covered is over forty years; the entries for twenty-four of these years are indexed al- phabetically by correspondent; and the whole document extends to pages. the epistolary record is useful to us in important ways besides telling us what we must hunt for; it is, for example, an almost magical means of establishing the dates of undated or muti- lated letters. d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u niversity user on a pril t h e american archivist finally, we go out and sniff the air and hunt for jefferson docu- ments. in jeremy belknap wrote his friend ebenezer h a z a r d about his recent trip to connecticut to gather in the great collec- tion of trumbull papers now reposing in the massachusetts his- torical society. h e expected, he said, to get some other papers from governor hancock's estate, "and when our old patriot s[am] a [ d a m s ] ' s head is laid, we hope to get more. there is nothing like having a good repository, and keeping a good look-out, not wait- ing at home for things to fall into the lap, but prowling about like a wolf for the prey." this is as sound a working principle now as it was then. t h e search so far has netted just over , separate docu- ments. this seemed a good point at which to make an analysis of our record of sources, the results of which i am pleased to present. these , pieces have been drawn from different sources, namely private owners (including dealers) and institu- tional owners (including clubs, banks, commercial firms, and schools, besides institutions primarily devoted to the preservation of historical materials). the private owners have contributed about documents as compared with about , from insti- tutional sources. a breakdown according to size of contribution shows that private and institutional sources have contributed only a single document apiece; have contributed from to documents; have contributed from to ; have contributed from to ; have contributed from to . at this point the private contributors drop out. five institutions have contrib- uted between and documents; have contributed from to ; and have contributed more than documents. t h e geographical distribution of our sources in the continental united states is shown in the following table. i. from to documents have been located in alabama louisiana oregon colorado minnesota vermont florida mississippi

jeffersonian material has been located, six have contributed a single document each, while the district of columbia alone has contrib- uted over half of our total holdings, specifically , documents. we are not wholly satisfied with the situation that this table re- flects. the concentration of sources in the east was predictable from historical causes, but it is unquestionably exaggerated by the fact that the eastern territory has been more thoroughly scoured. it is hardly credible, for example, that there are no jefferson pa- pers at all in several states through which lewis and clark trav- eled, or that in the great state of texas there is only one owner of jefferson autograph material. an additional word should be said about sources outside the continental united states. two territories (hawaii and puerto rico) have contributed to our file; also canada, australia, and seven countries in europe. the european countries have contrib- uted about in proportion as they have been scoured; thus france, holland, and switzerland, where mr. howard c. rice has per- sonally searched, have made substantial contributions, but our ef- forts to work by remote control, as in the british isles, have been relatively unfruitful. this brings me to a consideration of the searching that remains to be done. the figures given in my analysis above are bound to be altered substantially very soon by the accession of a very large body of material from the national archives which has been located and filmed but which, on account of our lack of shelf-space before moving into the firestone memorial library, has not been acces- sioned. an estimated , jefferson documents have been located there, the great bulk of them in the general records of the de- partment of state, and especially in the miscellaneous letters and diplomatic and consular correspondence. important groups and d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m

, or so documents, principally from the appointment and pardon papers in the state department records and from the senate and house of representatives files in the legislative records. there is besides, as we are acutely but at the moment helplessly aware, a good deal of searching yet to be done among the holdings of the division of manuscripts in the library of congress. be- tween thirty and forty of the l. c. collections, some of them run- ning to many thousand pieces, have been listed for examination as known or likely sources of jefferson material. we have had, mean- while, the inestimable benefit of mrs. vincent eaton's help in fur- nishing us with lists of the jefferson items in several of the major l. c. collections, most notably in the washington and madison papers. only a beginning has been made on the great l. c. collec- tion of manuscripts reproduced from foreign archives relating to american history. the coordination of this search with direct searches of the foreign depositories is a large problem so far only partially worked out. it will appear from this that the staff of three editors has its hands full and its work laid out. it will also perhaps help explain why copy has not reached the press and the volumes have not reached the public any faster. i turn now to a brief account of our handling of the material when it reaches us in the form of photofacsimiles. i l l our processing is extremely simple. a yellow control slip, per- forated in triplicate, is typed for each document and carries on it the date, the name of the writer (and recipient, if the document is a letter), the number of pages (exposures), the source, and the accession number. the accession number is stamped on the back of each page of the document facsimile. the document — and from this point i drop the term facsimile — is placed in a manila envelope marked with the same data. the perforated control slips are then separated and distributed in three files: a chronological file, an alphabetical file (letters being filed under the name of the writer or recipient other than jefferson), and an accession file. into the envelopes, which are filed on open shelves in chrono- logical order, go the transcripts and other editorial matter perti- nent to a given document, and also variant or duplicate copies of d ow nloaded from http://m

find two facsimiles in our file — one being the copy he retained, and the other the copy he sent. the recipient's copy is usually the more desirable on two counts: first, because press copies are often only semi-legible (though the poly- graph, which replaced the letterpress in , made perfect cop- ies), and, second, because the recipient's copy bears a direction, postal markings, endorsement, etc. the copies sent are of course more difficult to obtain, because they must be picked up individually or in small groups all over the map. in some instances we cannot transcribe a letter until we locate the copy sent. a spectacular ex- ample is jefferson's letter to robert r. livingston of april , instructing him, as minister to france, to acquire new or- leans for the united states. the text of this momentous document has often been printed but never in full, because the press copy in the library of congress is not completely legible. recently the museum of the city of new york acquired from a descendant of livingston the original copy sent. readers who compare the initial pages of the two texts, as reproduced in the accompanying illus- tration, will understand why our search continues. to record missing documents we have used blue slips perforated in triplicate like the yellow ones. (a "missing" document is any jefferson paper whose existence is verified but which has not yet been found in manuscript form.) the blue slips bear as much data as we can obtain on the fugitive item. our principal sources of in- formation about missing items are the epistolary record, auction records, and printed works, such as the great documentary collec- tions like force, contemporary newspapers, and the memoirs and writings of jefferson's contemporaries. a continuous search through the whole body of printed source materials, from jefferson's time to ours, goes on in our office. it has produced some surprises — including the ferreting out of one group of autograph letters in private hands — and it is an absorbing if interminable task. the printings of documents discovered in the course of the search are recorded on the control cards in the chronological file. this infor- mation is often useful in annotating a given document; sometimes it provides a printed text that is more satisfactory than the original manuscript itself, because prepared before the original had deterio- rated. an important subsidiary file in the jefferson office is the bibli- ography of publications by and about jefferson and his contempo- d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u niversity user on a pril t h e american archivist raries. this is kept on cards, of which there are now over , , and the entries under jefferson as subject are classified under such appropriate heads and sub-heads as "agriculture — plows," "cam- paign literature," "jews, relations with," "medicine — vaccina- tion," "portraits," "visitors," and so on. we are always eager to enlarge our file of allusions to jefferson in both published and unpublished writings of his day, and have supplemented our main document file with a considerable body of typescripts and photo- duplicates of material under the rubric of "contemporary com- ment." iv a brief account of the plan of the edition will conclude this paper. about four-fifths of the material to be printed will be arranged in a single chronological sequence, making up volumes to and embracing all the correspondence, all messages, reports, bills, and dated and datable memoranda. the remaining fifth of the material is being gradually segregated for printing in a classified series, as- sumed to be volumes to , which will embrace, first, jeffer- son's larger published and unpublished writings and papers (the notes on virginia, parliamentary manual, autobiography, anas, "life and morals of jesus," the anglo-saxon grammar, account books, farm and garden books, etc.), and, second, such other papers as can be most satisfactorily used and edited in classified groups, e.g., the legal papers, the architectural drawings, and the maps and surveys. for the three groups of papers last men- tioned, arrangements have been made for more or less independent editing by specialists. a separate supplementary volume is planned as a biographical register or dictionary for the entire work. it will contain concise sketches of all of jefferson's correspondents and of other persons mentioned in the work who had significant or continuing relations with jefferson. in treating well-known figures (say madison or vergennes), emphasis will be placed upon their connection with jefferson; for obscurer figures (jefferson's french cook, or the brazilian adventurer jose da maia), an effort will be made to be more exhaustive. the advantages to readers in having a separate volume, in which they can readily find the master footnote on any given person, are obvious. the advantage to the editors is likewise obvious, for the editorial notes will by this device be relieved of a great deal of matter, much of it repetitive. plans for indexing call tentatively for a throw-away index for d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u niversity user on a pril t h e papers of thomas jefferson every five volumes of text, with a cumulative index in the required number of volumes at the end. as for annotation, we have arrived after a good deal of thought and experimenting at the conclusion that exhaustive annotation of such a large mass of documents is not feasible, even if it were de- sirable. w e have stated that our purpose in annotating is to pro- vide information essential to understanding each document pre- sented. ideally considered, such a purpose would frequently entail a prodigious amount of research in order to set forth the archival and bibliographical history of each document and assess its his- torical significance; to identify or explain all persons, events, and places, and to point out jefferson's relationship therewith; to sep- arate fact from rumor; to explain obsolete, technical, and regional t e r m s ; to trace literary quotations to their sources; to furnish ref- erences to the pertinent literature; and so on. all this and more is "essential to understanding the document" in the fullest sense of the term. yet to place no restriction on such a purpose would con- fuse the functions, on the one hand, of biographers and historians and, on the other, of editors. i t would not infrequently produce explanatory material well in excess of the documents explained, and it would add to the considerable task of the editor a burden greater than that even assumed by the biographer or historian, since they can and must select, whereas the editor cannot do so. t h e providing of "information essential to understanding the document" does not, according to our interpretation, oblige us to explain those common allusions to person, events, places, and terms which the specialist may be presumed to know or which he may find in sources or reference works as readily accessible to him as to the editors. notes on these topics will, however, be furnished when the editors find themselves in possession of new facts gath- ered in the ordinary editorial process or when they have necessarily explored sources not readily accessible. furthermore, routine stand- ards will not be applied in annotating documents that are of special importance or that present unusual features or problems. in other words, we shall try, in our capacity as editors, to solve such prob- lems as we can and to show the way toward the solution of as many others as we can. in so doing we hope to improve upon our prede- cessors, most of whom have been conspicuously irresponsible in these matters, and to approach the stature of the late and very great editor edmund c. burnett. but we do not propose to arro- d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u niversity user on a pril t h e american archivist gate to ourselves the whole vast scholarly province of jefferson and his times. the form of annotation we have settled upon may sound at first as if it were more ingenious than practical; but we have found it admirably flexible, and we believe it will best suit the widely vary- ing purposes of readers. there will be a single inclusive footnote for all except very long or very special kinds of documents. i t will be printed, in double-column and in a smaller point of type, im- mediately following the document to which it pertains, not at the foot of the page. the note will always be divided into at least two, and sometimes into three, sections or paragraphs. the first section is descriptive and will furnish physical data, such as the nature of the document (whether a draft, a recipient's copy, etc), the loca- tion of the original and of other copies if known, the address and endorsement, notation of enclosures, comment (when called for) on the handwriting or the condition of the manuscript, and the like. the second section (or paragraph) of the inclusive note is ex- planatory. within the limitations stated above, it will be a com- bined commentary and series of explanations of particular topics in the document. the key words of the topics annotated will be printed in small capitals in the note, so that the eye may readily travel from an allusion in the text to the point where it is treated in the note. the source of each item of information will follow that item parenthetically in the explanatory note. for this purpose short titles will be employed for all works commonly cited. a list of these, with their expanded forms, will be printed periodically, probably with each installment of the index, and the cumulative bibliography at the end of the work will constitute a union list of all short titles used. a third section (or paragraph) will appear in the inclusive note only when a document presents special problems, such as variations between a draft and a fair copy, matter lined out that deserves to be recorded, and the like. these textual notes will be keyed to the text by means of superscript numerals. except in the case of docu- ments of special literary or historical significance (such as the notes on virginia and the great state papers), we have not committed ourselves to recording every textual variation between extant copies. our decisions on presenting the texts themselves are the product of much thought and conscience-searching on our part, together with an abundance of advice and admonition from without. w e have recognized from the outset what some editors have never d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .h g by c arnegie m ellon u

domain of vdac is necessary for bak insertion to the outer mitochondrial membrane and tbid - induced cytochrome c release? a wednesday, february , voltage-dependent anion channel isoform (vdac ). here, we show that hcc induced by carcinogenic compounds, aflatoxin or den is highly sensi- tized to tbid-induced omm permeabilization and cyto c release when com- pared to normal liver. expression levels of vdac and bak were also higher in hcc than in control liver. the role of the vdac -bak pathway in the differential tbid sensitivity was validated by overexpression of vdac in primary hepatocytes. in hcc cells, elevation of bak was also associated with an increased level of mcl- , an inhibitor of bak. furthermore, both constitutive and drug-induced genetic deletion of mcl- in mouse embryonic fibroblasts caused sensitization to tbid-induced omm permeabilization in the absence of a change in bcl-xl or bax . based on these results, we are evaluating the possibility of selective killing of hcc cells by the combination of a bak activator and an mcl- inhibitor. -pos board b which domain of vdac is necessary for bak insertion to the outer mitochondrial membrane and tbid - induced cytochrome c release? shamim naghdi , peter varnai , soumya sinha roy , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadlephia, pa, usa, semmelweis university, budapest, hungary. vdac proteins represent a main component of the outer mitochondrial membrane (omm). the vdac family is composed of isoforms with more than percent similarity. although their primary role was known to be in ion and metabolite transport between mitochondria and cytosol, it has been dis- covered that vdacs are also involved in apoptotic pathways. we have recently found that specifically the vdac isoform is needed for tbid-induced cyto- chrome c release, due to its role in supporting bak insertion to the omm (roy et al. . embo rep. : - ). to determine the domain(s) of vdac which supports bak insertion, vdac and vdac amino acid composition compared and the unique attributes of vdac sequencewereconsideredformutationalanalysis.totestfunctionalsig- nificance of the changes in vdac or vdac , vdac -/- mef cells that are resistant to tbid, were transfected with the mutants and insertion of bak to the omm and cytochrome c release were monitored in permeabilized cells by immunoblotting. previously, we showed that the vdac -specific n terminal tail and cysteins are dispensable for tbid-induced omm permeabilization. to approach the remaining differences four chimeras were prepared: vdac ( - )vdac ( - ), vdac ( - )vdac ( - )vdac ( - ), vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ). these studies revealed that tbid dependent omm permeabilization is only sup- ported by vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ), indicating that the first two third of vdac is required and sufficient for bak targeting to the omm and tbid induced cytochrome c release. -pos board b outer mitochondrial membrane protein distribution and function depend on mitochondrial fusion david weaver , xingguo liu , veronica eisner , peter varnai , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary. cells and tissues deficient in mitochondrial fusion have been shown to have defects linked to the exchange of inner membrane (imm) and matrix compo- nents, particularly mitochondrial dna. outer membrane (omm) constituents originate in the cytoplasm, thus the role of intermitochondrial transfer of omm components by fusion remained unexplored. here we show that fibro- blasts lacking the gtpases responsible for omm fusion, mfn / , have a more heterogeneous distribution of omm proteins than wild-type cells, and in partic- ular that heterogeneity of pro-apoptotic bak leads to dysregulation of bid- dependent apoptotic signaling. homogeneous distribution of bak is partially rescued by introduction of mfn into mfn / -/- cells. furthermore, fusions be- tween mitochondria lacking and containing bak result in hybrids sensitive to bid. proteins with different modes of omm association display varying degrees of heterogeneity in mfn / /- cells and different kinetics of transfer during fusion in fusion-competent cells. efficient coupling of omm to imm fusion depends on the presence of both mfn isoforms and is antagonized by the mitochondrial fission protein, drp . thus, omm function depends on mitochondrial fusion and is a locus of dysfunction in conditions of fusion deficiency. -pos board b mitochondrial fusion dynamics in skeletal muscle of healthy and diseased rat veronica eisner , guy lenaers , gyorgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, inserm u- , institut des neurosciences de montpellier, montpellier, france. mitochondria are highly mobile and dynamic organelles in many cell types. however, in the muscle, mitochondria are crammed into the narrow space among the myofilaments. until now, it remained unclear if mitochondrial fusion occurs in and supports the contractile activity of skeletal muscle (sm). here we applied mitochondria matrix-targeted dsred and photoactiv- able gfp to study mitochondrial fusion in rat fdb sm fibers. in vivo electro- porated fibers were imaged by confocal microscopy. when we tagged the mitochondria in ~ % of cell area with twophoton photoactivation of gfp, rapid spreading of fluorescence showed subsets of interconnected mitochondria, mostly in longitudinal direction. matrix fusion occurred with a rate of . and . events/min in adult fibers and skeletal myotubes, respectively. expres- sion of autosomal dominant optical atrophy-causing mutants of the fusion protein opa or ethanol exposure caused suppression of fusion, which is fol- lowed by mitochondrial dysfunction and late onset myopathies. when chal- lenged by repetitive tetanic stimulation, ethanol exposed cells displayed intracellular ca þ dysregulation, appearing as a fatigue pattern. ethanol also induced a decrease in mfn protein levels, without significantly altering mfn , opa or deltapsi. depletion of mfn alone was sufficient to suppress mi- tochondrial fusion in fdb fibers. fusion inhibition was apparent before any cell dysfunction, suggesting that suppression of fusion is not secondary to other problems in the cells. to directly test the role of mfn in ca þ regulation, ryr -transfected control and mfn ko mefs were stimulated with caffeine. mfn ko cells showed oscillatory ca þ transients that decayed faster than that in the control. thus, fusion dynamically connects skeletal muscle mito- chondria and serves as a target mechanism of both mutations and environmen- tal cues to cause impaired excitation-contraction coupling. -pos board b bcl- proapoptotic proteins distribution in u- mg glioma cells before and after hypericin photodynamic action katarina stroffekova, lucia balogová, mária maslaňáková, lenka dzurová, pavol mi�skovský mi�skovský. safarik university, kosice, slovakia. apoptosis is a key process in the development and maintenance of tissue homeostasis. this process of controlled cell death is tightly regulated by a balance between cell survival and damage signals. we focused our attention towards the intrinsic mitochondrial apoptotic pathway, where bcl- family of proteins plays the major role. we were particularly interested in two pro- apoptotic players bak and bax. here we investigated their role in apoptosis triggered by photodynamic action. we show the localization of bax and bak in u- mg human glioma cells incubated with photosensitizer hypericin (hyp) before and after photodynamic action. apoptotic stimulus by hyp photodynamic action caused bax translocation into mitochondria. however our results suggest that under these condi- tions there are two populations of mito- chondria: one which contains bax and bak simultaneously, and is almost exclu- sively localized near the plasma mem- brane; the other which contains bax only and is distributed throughout the cell. the different protein content and spatial distri- bution of these two populations suggest that they can play different roles in re- sponse to apoptotic stimuli. -pos board b stimulation of bax mitochondrial localization by bcl-xl thibaud renault , oscar teijido , gisele

mitochondria through protein-protein interactions between the bcl- family proteins. an imbalance of this interaction network due to the up-regulation of the proto-oncogenes bcl- and/or bcl-xl lead to a resistance to apoptosis and is associated with tumor formation. bcl-xl overexpression act at the level of the mitochondrial outer membrane (mom) by inhibiting bax-mediated apoptosis; more particularly mac formation and cytochrome c release. how- ever, the molecular mechanisms through which bcl-xl affect earlier steps of bax-mediated apoptosis are not fully understood. surprisingly, we found that mitochondrial bax redistribution and change of conformation were not inhibited but rather spontaneously increased in response of bcl-xl overexpres- sion. in order to further investigate the molecular mechanisms involved in this which domain of vdac is necessary for bak insertion to the outer mitochondrial membrane and tbid - induced cytochrome c re ... outer mitochondrial membrane

american memory project from the library of congress bahri ata* Öz dijitalleşen bir dünyada, dünyayı ve problemlerini sınıfın dört duvarı arasında bir temel ders kitabına dayalı olarak öğrenmek genç nesiller için hoşnut edici midir? İnternet ve web siteleri yaşamımızı bütün boyutlarıyla derinliğine etkilemektedir. bu yenilikler modern sınıflarda öğretmenlerin davranışlarını ve öğretim tekniklerini de etkilemektedir. 'lardan sonra kongre kütüphanesi'nin amerikan hafıza projesinin sunduğu birincil ve ikincil kaynaklar, hem abd'de hem de diğer ülkelerde sosyal bilgiler eğitimini oldukça etkilemeye başlamıştır. bu makalenin amacı kongre kütüphanesi tarafından yürütülen amerikan hafıza projesi ve sosyal bilgiler eğitimine etkisini tanıtmaktır. bunun için, doküman analiz yöntemini kullandım. Özet olarak, bu proje, . yüzyılda sosyal bilgiler ve tarih'i öğretmede türk kütüphane ve okullarına ortaklık yolunda iyi bir örnek olabilir. anahtar sözcükler: sosyal bilgiler eğitimi, tarih eğitimi, kongre kütüphanesi, amerikan hafıza projesi abstract in the digitalized world, is it satisfactory for younger generations to learn world and its problems on the basis of a basal textbook among four walls of their classrooms? the internet and web sites are affecting all dimensions of our life very deeply. these innovations has changed the teacher's professional behaviors and instructional doç. dr., gazi Üniversitesi gazi eğitim fakültesi Öğretim Üyesi. e-posta: bahriata@gazi.edu.tr mailto:bahriata@gazi.edu.tr | konuk yazar / guest author bahri ata techniques in the modern classroom. after 's, the american memory project by the library of congress with its huge sources of primary and secondary materials began to affect the social studies education on both usa and other countries. the aim of this article is to introduce the american memory project conducted by the library of congress and its influence on social studies education. for this, i used document analysis method. in sum, this project can be a good example for turkish libraries and schools on the way of partnership to teach social studies and history in the st century. keywords: social studies education, history education, the library of congress, american memory project giriş dünyanın, dijital bir ortama dönüşmeye başladığı günümüzde teknoloji, pek çok geleneksel kurumu etkilemekte okul ve kütüphaneler de bunlardan payını almaktadır. günümüzde okullardaki genç nesillerin, sınıfın dört duvarı arasında tek bir ders kitabına bağlı kalarak dünya ve sorunları konusunda eğitim almaktan memnuniyet duymayacakları aşikârdır. buna bağlı olarak, teknolojinin kullanıldığı modern sınıflarda öğretmenin meslek davranışları ve öğretim yöntemleri de derinden etkilenmeye başlamıştır. bilindiği gibi kütüphaneler bir kurum olarak, sosyal bilgiler eğitiminin çok önemli bir bilgi kapısı görevini üstlenmektedir. sosyal bilgiler eğitimi çerçevesinde gerek öğretmen adaylarına gerekse öğrencilere kütüphanede araştırma yapma becerisi kazandırmanın önemi ortadadır. türkiye'de yılında hazırlanan ilköğretim programları, kütüphane kullanma becerisinin gelişimine ve araştırmacı öğrenci yetiştirmeye özellikle önem vermiştir. teknolojideki değişim rüzgârları kütüphaneleri de etkilemektedir. böylece “dijital kütüphane” ya da “karma (hybrid) kütüphane” denilen bir tür ortaya çıkmıştır (afzali, ). abd'deki kongre kütüphanesinin, bu tür kütüphanecilik anlayışında öncü bir rol oynadığı dikkati çekmektedir. diğer yandan küreselleşmenin etkisinin en şiddetli biçimde yaşandığı günümüzde pek çok ülke, hafıza mekânlarını dijital kütüphanelere aktararak koruma ve eğitim amaçlı olarak kullanma yarışı içine girmiştir. hiçbir ülke de bu yarışta geride kalmak istememektedir. bu tür dijital kütüphaneler, oluşturmacı sosyal bilgiler eğitimini sınıf ortamında daha mümkün kılmakta ve kolaylaştırmaktadır. sosyal bilgiler eğitimini, oluşturmacı sosyal bilgiler eğitiminde İyi bir Örnek: abd kongre kütüphanesinin amerikan hafıza projesi a good example of social studies education: the american memory project from the library of congress | (konstrüktivist) anlayışa uygun olarak gerçekleştirebilmek, öğrencilerin birinci elden kaynaklarla haşır neşir olmasını gerekli kılmaktadır. aslında tarih eğitiminde birinci kaynaklarla ders yapmak fikri çok eski olup kökenleri alman pedagoglar tarafından 'lere dayandırılan “kaynak yöntemi” (source method) düşüncesine kadar gitmektedir. İngiltere'de ise kaynaklarla tarih öğretimi konusunda ile arasında ilk coşku dalgası yaşanmış ve oxford Üniversitesinde çalışan eğitimci m. w. keatinge'in önemli katkıları olmuştur (osborne, , s. ). esasen on yıl önceki yazılarımda amerikan hafıza projesi'nden (bk. http://memory.loc.gov/ammem/index.html) kısaca söz etmiştim. daha sonra meslektaşlarım doğan ile dinç ( ) ve doğan ( ) da çalışmalarında amerikan kongre kütüphanesinin “amerikan hafıza” sitesinde yer alan, derslerde birincil kaynakları kullanma yaklaşımına ve gerekçeleri konusuna yer verdiler. aslında abd'de çevrim içi birinci elden kaynak hizmeti veren pek çok kurum bulunmaktadır. Örneğin ulusal arşiv ve kayıtlar yönetimi (nara), yale, northwestern, cornell, mississippi state, virginia Üniversiteleri, vassar koleji, franklin ve eleanor roosevelt enstitüsü gibi pek çok kurum birinci elden kaynak veri tabanına sahiptir. 'da abd'de bulunduğum sırada yaptığım okul gezilerindeki gözlemlerim ve kongre kütüphanesindeki incelemelerim sırasında bu projenin ve sosyal bilgiler eğitimine etkisinin çok daha detaylı bir çalışmayı gerektirdiğini fark ettim. bu proje, gerçekten eğitimde çok çağdaş ve iyi bir örnektir. genelde her eğitimcinin özelde de sosyal bilgiler eğitimcilerinin yurt dışındaki bu türden projelerden haberdar olması gerektiğini düşünmekteyim. Öğretmenlerden gelecek bir talep üzerine, ülkemizdeki ilgili kurumların benzer ve daha iyi projeler yapmasını sağlayacağına gönülden inanıyorum. bu makalenin kaleme alınma amacı, söz konusu projenin nasıl başladığını, nasıl geliştiğini, sosyal bilgiler eğitimine etkisini ortaya koymak ve türkiye'deki sosyal bilgiler eğitimcilerine tanıtmaktır. böylece yakın gelecekte türkiye'de de buna benzer ulusal projeler için felsefi ve pedagojik bir çerçeve oluşturmak amaçlanmaktadır. projeye ve etkilerine geçmeden önce abd kongre kütüphanesinin tarihçesinden kısaca söz etmek yerinde olacaktır. abd kongre kütüphanesinin Önemi bu kütüphane, 'de washington, dc.'de amerikan ulusal yasama organı mensuplarının ihtiyaçlarını karşılamak üzere küçük bir araştırma kütüphanesi olarak http://memory.loc.gov/ammem/index.html | konuk yazar / guest author bahri ata kurulmuştur. kütüphane, zaman içinde eğitim ve akademik amaçlarla tarihsel ve kültürel materyalleri korumayı amaç edinmiştir (hubbell, ). 'te britanya askerleri kongrenin küçük hukuk kitapları koleksiyonunu yakmışlardır. 'te thomas jefferson, kitaptan oluşan kendi özel kitap koleksiyonunu kongre kütüphanesine vererek buranın yeniden kurulmasını sağladı. yangınında bu kitapların üçte ikisi yanmıştır. 'ten sonra kütüphane, aynı zamanda birleşik devletler telif hakları ofisinin mekânı oldu. 'de kütüphane bugün thomas jefferson binası olarak adlandırılan İtalyan rönesans stilindeki binasına geçti. 'da hemen arka tarafına adams binası inşa edildi. 'de madison binası yapıldı. bu binaları yeraltından geniş tünel geçitler de birbirine bağlamıştır. thomas jefferson binası, 'de büyük bir restorasyona tabi tutularak 'de tekrar açıldı. abd kongre kütüphanesi, milyon ürünü ile günümüzde dünyanın en zengin kütüphanelerinden biridir. turistler tarafından en çok ziyaret edilen yapılardan biridir. Örneğin 'de milyon bin kişi burayı ziyaret etmiştir (anonim, ). kongre kütüphanesi, farklı hizmet vermekte olup “dünya dijital kütüphanesi, myloc.gov, veterans (gaziler) tarih projesi, Öğretmenler, ziyaretçiler, araştırmacılar, kütüphaneciler-arşivciler, Çocuklar ve aileleri” sayfaları hemen dikkati çekmektedir (bk. http://www.loc.gov/index.html). verilen hizmetlerin içinde üç hizmetin, doğrudan öğretmenlere ve öğrencilere yönelik olarak eğitim amaçlı kurulduğu görülmektedir. bunlar; “amerikan hafızası, myloc.gov, Öğretmenler sayfası”dır. makalemi daha çok dijital tarih ve kültür materyallerini içeren amerikan hafızası projesi ile sınırlamaya çalıştım. aslında bir başka çalışmada da diğer projeleri ele almak mümkündür. amerikan hafızası projesi nedir? amerikan hafıza projesi ile doküman, gazete makalesi, yazma, nadir eser, kitap, görüntü, harita, karikatür, film, fotoğraf ve ses ve müzik kayıtlarından oluşan . milyon birinci elden tarihsel kaynak dijital ortama aktarılarak arşivlenmiş ve bir arama motoru oluşturulmuştur. bunlara ilişkin olarak öğretmenlerin sınıf içinde kullanabileceği ders materyalleri de geliştirilmiştir. amerikan hafızası projesi esas olarak . yüzyıla kadar dokümanlar içermekle birlikte, ve . yüzyıla ait amerikan yaşamının değişik boyutlarına ilişkin binlerce kanıt sunmaktadır. afzali'ye myloc.gov http://www.loc.gov/index.html myloc.gov sosyal bilgiler eğitiminde İyi bir Örnek: abd kongre kütüphanesinin amerikan hafıza projesi a good example of social studies education: the american memory project from the library of congress | göre ( , s. ) bu proje, dijital kütüphaneciliğin ilk örneği olarak da kabul edilmektedir. bu proje, pilot program olarak 'da başlamış olup 'e kadar sürdü. okul ve kütüphane pilot projenin bir parçası olarak bu materyalleri içeren cd-rom'ları aldılar. ortaokul ve lise öğrencileri, bu pilot uygulama sırasında daha fazla dijital kaynak istediklerini belirtmişlerdir. 'te kütüphane, “ulusal dijital kütüphane programı”nı kurmak için milyon dolarlık bir bağış bulduğunda, amerikan hafızası projesi bu programın bir tür amiral gemisi oldu. bu projenin toplam masrafı yaklaşık milyon dolar olup kısmen birleşik devletler kongresi tarafından, büyük oranda da özel sektör tarafından karşılanmıştır. Örneğin kongre, bu proje için milyon dolarlık federal yardım yapmıştır. w.k. kellogg vakfı, 'te milyon dolar bağış yapmıştır . bu vakıf, kurulmuş olup amacı cinsiyet, ırk, inanç, milliyet farkları gözetmeksizin çocukların ve gençlerin doğrudan ya da dolaylı olarak sağlık, konfor, eğitim, beslenme, giyinme, barınma ve korunması için gerekli fonların yönetimi için kurulmuştur (w.k. kellogg foundation, ). 'de . yüzyıldan . yüzyıla doküman, arkasından “amerikan tarihinde sözler ve eylemler koleksiyonu, panoramik fotoğraflar ( - ), kadın oy hakkı mücadelesi fotoğrafları ( - )” ilk olarak çevrim içi (online) aktarılan koleksiyonlardandır. 'de harvard Üniversitesi tasarım okulundaki frances loeb kütüphanesi de amerikan hafıza web sitesine dâhil edildi. böylece ortaya “amerikan manzara ve mimari tasarım ( - )” web sunumu ortaya çıktı. bu sunum, fotoğraflarla birlikte, planlar, haritalar ve modeller içermektedir. 'de İspanya-amerika savaşı'nı gösteren hareketli resimler koleksiyonu çevrim içine eklendi. eğitimde müziğin kullanılmasının yaygınlaşmasına odaklanmış olan texaco kuruluşu da bu programa katkıda bulundu. amerikan halk yaşam merkezinin tarihli koleksiyonları da bunlara eklendi. bunların arasında - yılları arasında “yorganlar ve yorgancılık” ile ilgili bir koleksiyon da bulunmaktadır. 'da kongre kütüphanesi, amerikan hafızası web sitesine “aleksander graham bell'in aile belgeleri, efemera, güney teksas sınırını gösteren görsel kaynaklar ( - ), kuzey rio grande'nin hispanik müziği ve kültürü” gibi | konuk yazar / guest author bahri ata koleksiyonları dijital ortama aktarmıştır. bu tarihe kadar 'den fazla koleksiyon çevrim içi ortama aktarılmış oldu (balas, , s. ). 'da social studies (sosyal bilgiler) dergisinde sosyal bilimler eğitimi konsorsiyumunun yöneticilerinden ve bu sitedeki pek çok ders planını geliştirenlerden laurel r. singleton ve james r. giese tarafından öğrencilerle birinci elden doküman kullanmanın çerçevesinin anlatıldığı bir makale kaleme alındı. söz konusu makalede, sınıfta birinci elden kaynak kullanmanın mantığı ve nasıl yapılacağı konusu özetlenmiştir (singleton ve giese, ). 'te “thomas jefferson doküman koleksiyonu” da amerikan hafıza web sitesine aktarıldı. böylece washington, lincoln ve jefferson gibi amerikan başkanları ile ilgili materyaller çevrim içi ortama aktarılmış oluyordu. 'da son yapılan değişikliklerle birlikte amerikan hafızası projesi sayfasında şu linkler vardır: “başlıklarına göre koleksiyonlar, koleksiyonlarla İlgili İlginç noktalar, tarihte bugün, Öğretmenler, kütüphaneciye sorun”. aynı yıl koleksiyon sayısı 'u bulmuştur. koleksiyonlar; başlıklarına, dönemlerine, içerdikleri materyalin türüne (harita, yazma, müzik, fotoğraf, hareketli film gibi) ve ait oldukları bölgelere göre sınıflandırılmıştır. başlıklar; “reklamcılık, afrikalı-amerikalıların tarihi, mimarlık-manzara, Şehirler-kasabalar, kültür-halk yaşamı, Çevre-koruma, hükümet-kanun, göç-amerikan genişlemesi, edebiyat, haritalar, yerli amerikalılar tarihi, performans sanatları, müzik, başkanlar, din, spor ve rekreasyon, teknoloji ve endüstri, savaş askerlik, kadın tarihi” isimlerini taşımaktadır. yıllara göre baktığımızda temmuz verilerine göre, - arası için koleksiyon, - dönemiyle ilgili koleksiyon bulunmaktadır. ile günümüze ait koleksiyon bulunmaktadır. bu projenin ve . yüzyıl amerikan tarihi ve kültürü açısından oldukça zengin malzemeye sahip olduğu anlaşılmaktadır. “koleksiyonlarla İlgili İlginç noktalar” ise “uygulamalı diller merkezinin amerikan İngilizcesi diyalektleri ile alfred whital stern'in lincoln koleksiyonu”nu içermektedir. “tarihte bugün” sayfasında da “kaynaklar, arşiv ve bugün” linkleri bulunmaktadır. “Öğretmenler” sayfası; “sınıf materyalleri, mesleki gelişim, tps partnerleri, birincil kaynakları kullanma, haberler ve olaylar, ek kaynaklar ve faks” gibi kısımları içermektedir. sosyal bilgiler eğitiminde İyi bir Örnek: abd kongre kütüphanesinin amerikan hafıza projesi a good example of social studies education: the american memory project from the library of congress | “sınıf materyalleri” de “ders planları, tematik kaynaklar, birincil kaynaklar seti, sunu ve etkinlikler, koleksiyon bağlantılarını içermektedir. kısaca bu web sayfalarında öğretmenin sınıf içinde birinci elden her türlü kaynağı nasıl kullanması gerektiği ile ilgili örneklerle zenginleştirilmiş bilgiler bulunmaktadır. amerikan hafızası projesi'nin sosyal bilgiler eğitimine yansımaları nelerdir? 'den sonra amerikan hafıza projesi'nin sosyal bilgilere etkileri üç alanda kendini hissettirmeye başladı. bunlar öğretim materyallerinin hazırlanması, öğretmene hizmet içi eğitim ve uzaktan eğitimdir. Öğretmenler açısından karşılaşılan en büyük problem ders işleniş sürecini, bu çok sayıdaki kaynağı kullanarak tasarlamak ve bunları derste uygulamak olmuştur. bu problemle başa çıkmak için kongre kütüphanesi, deneyimli öğretmenlerle birlikte ulusal öğretim programı standartlarını da göz önüne alarak “öğretmen kaynakları modülü” nü hazırladı. bu modül; ayrıntılı ders planlarını, uygulamaya yönelik iyi hazırlanmış yönergeleri, performans değerlendirme ölçeklerini (rubrik) içermektedir. modül aynı zamanda birinci elden kaynakların sınıfta nasıl kullanılacağı, doküman, harita ve fotoğrafların bilgi ve tarihsel kanıt için nasıl değerlendirileceği konusunda eğitimcilere bilgi sağlamaktadır. İşte bu materyallerle öğretmenler sınıflarında kolayca oluşturmacı öğrenme ortamı oluşturabilmektedir. böylece öğrenci, bir sosyal bilimci ve tarihçi gibi kaynakların üzerinde kendi çalışabilir. bu malzemeleri kullanarak kendi sunusunu hazırlayabilir ve kendi sonucuna ulaşabilir. Örneğin, birinci dünya savaşı ile ilgili her türlü kaynağı inceleyen ve bu kaynakların nasıl ve niçin üretildiği üzerine kafa yoran öğrenciler, bir sonraki derste amerikan liderlerinin kendi dönemlerinde yaptıkları konuşmalarını dinlemişler, tarihsel olgu ile tarihsel yorumu birbirinden ayırmanın mümkün olup olamayacağını tartışmışlardır. Üçüncü derste öğrenciler amerika'nın savaşa katılımı ile ilgili “microsoft publisher” programını kullanarak farklı görüşleri yansıtan ve gazete personeli olarak kendi aralarında iş bölümü yaptıkları iki farklı gazete hazırlamışlardır (lincoln, ). kongre kütüphanesi, - arasında amerikan hafıza bursiyer (fellows) programı adı altında öğretmenler için hizmet içi eğitim programları da uyguladı. 'da kongre kütüphanesi, öğretmenlerin “amerikan hafızası tarihsel | konuk yazar / guest author bahri ata koleksiyonu”nun sınıf içinde kullanılmasında öğretmenleri eğitmek için madison binası'nda ulusal dijital kütüphane merkezini kurdu. microsoft da yardımları ile merkezin yenileşmesine önemli katkı sağladı. Çalıştaylarda öğretmenler, kütüphane personeli ile birlikte çalıştılar. Öğretim programı boyunca on-line tartışma programlarına da katıldılar. - yılları arasında bu programlara öğretmen katıldı. 'den sonra program, “eğitim sosyal yardım programı” adını aldı (veccia, ). bu tarihten sonra amerikan hafıza bursiyer (fellow) enstitüsü washington'da kütüphanecilerin, medya uzmanlarının ve öğretmenlerin katıldığı burs programları için altı günlük iki oturumdan oluşan çalıştaylar düzenlemeye devam etti. pek çok eyalette sosyal bilgiler ve tarih öğretmenlerine yönelik birinci ve ikinci elden kaynakların nasıl kullanılacağı ile ilgili hizmet içi eğitim kapsamında kurslar da düzenlenmiştir. hazırlanan materyaller, kongre kütüphanesinin “Öğrenme sayfası'na” konuldu. bu materyaller . sınıftan . sınıfa kadar ders planlarını, kaynakları, sunuları, amerikan tarihi ile ilgili etkinlikleri kapsamaktadır. oluşturmacı sosyal bilgiler ya da tarih dersleri için lise düzeyinin beklenmediği, ilköğretim için de benzer materyallerin hazırlandığı dikkati çekmektedir. bu materyaller kolayca ulaşılabilir olmasının yanı sıra, sürekli güncellenmektedir ve parasızdır. kütüphane ayrıca kitaplar ve cdrom'lar da yayınladı. 'de sosyal bilgiler programının kimlik, güç, çevre ve kültür gibi temalarının etrafında sosyal bilgiler üniteleri hazırlayarak bunları bir cd'de topladı. yine aynı yıl birinci dünya savaşı gibi pek çok konuya ilişkin üniteler tasarlanarak özellikle eğitimciler için kütüphanenin öğrenme sayfasına konuldu. sınıf içinde kullanılan etkileşimli (interaktif) akıllı tahtalar da dijital kaynaklardan yararlanmayı daha fazla kolaylaştırıyordu. bununla beraber elektronik ortamda birinci elden kaynakları kullanmanın öğrencilerin tarihsel anlayışlarının gelişimine ilişkin pek çok kaynak olmakla beraber, doğrudan amerikan hafıza projesi'nin öğrencilerin tarihsel anlayışlarının gelişimine etkisi ile ilgili amprik bir çalışmaların yapılmış olabileceğini düşünüyorum. ancak henüz bu tür çalışmalara ulaşamadım. sonuç ve tartışma kongre kütüphanesi, her türlü tarihsel dokümanın koruma ve eğitim amacıyla sanal ortama aktarılması olarak özetlenebilecek olan amerikan hafıza projesi ile önemli bir sosyal bilgiler eğitiminde İyi bir Örnek: abd kongre kütüphanesinin amerikan hafıza projesi a good example of social studies education: the american memory project from the library of congress | rol oynamıştır. 'den beri kongre kütüphanesi hizmet içi eğitimlerle ve uzaktan eğitim materyalleri ile bu projenin çıktılarının ülke çapında yaygınlaştırılması için çaba sarf etmektedir. amerikan hafızası projesi, abd kongre kütüphanesinin, unesco ve diğer kütüphanelerle birlikte 'da başladığı “dünya dijital kütüphanesi” adındaki bir başka proje için de bir model olmuştur. Özel sektör, İnternet arama şirketleri ile kütüphaneler arasındaki bu girişim örnekleri, türkiye için de iyi birer örnek oluşturmaktadır. hafıza mekânlarını aktarma projesi, ülkemiz gibi pek çok ülkeye tarihsel dokümanları gelecek nesillere aktarmak ve eğitim amaçlı kullanmak için sanal ortama transfer etmede ilham vermektedir. Ülkemizde de kongre kütüphanesine benzer bir şekilde, millî kütüphane, meclis kütüphanesi, türk tarih kurumu kütüphanesi, devlet arşivleri genel müdürlüğü ve talim ve terbiye kurulu başkanlığı gibi kurumlar ayrı ayrı koleksiyonlarını sanal ortama aktarmalıdır. Örneğin devlet arşivleri genel müdürlüğü gibi kurumlar bu işte oldukça yol kat etmişlerdir. Özellikle bu kurumlar hafıza mekânlarımızı oluşturan kaynakların toplanması, sınıflanması ve sanal ortama aktarılması konusunda iş birliği yapabilmelidirler. elbette tarihle ilgili çevrim içi veri tabanlarının artması durumu tarihçilerin de bilgi arama davranışlarını etkileyecektir. bununla beraber, birinci'nin ( , s. ) de belirttiği gibi teknoloji ne kadar gelişirse gelişsin, tarihçilerin arşiv kaynaklarının daima orijinalini tercih edecekleri söylenebilir. bu işlemlerle eş zamanlı olarak bu materyallerin eğitim amaçlı kullanılması üzerinde de çalışmalar yapılmalıdır. millî eğitim bakanlığı tarafından deneyimli sosyal bilgiler ve tarih öğretmenlerine dersin öğretim programları göz önünde bulundurularak örnek etkinlikler içeren cdrom'lar, kitaplar ya da internet sayfaları hazırlatılabilir. daha sonra bunları türkiye çapında öğretmenler arasında yaygınlaştırmak aşaması gelmektedir. bunun için de millî eğitim bakanlığı ile iş birliği içinde hizmet içi eğitim seminerleri düzenlenmesi gereklidir. bu çerçevede talim ve terbiye kurulu eski başkanı prof. dr. ziya selçuk döneminde talim ve terbiye kurulu başkanlığı'nın öğretmenler için hazırlamaya başladığı “etkinlikler havuzuna” (portal) işlevsellik kazandırılabilir. | konuk yazar / guest author bahri ata bütün bunlar yapılırken çözülmesi gereken en önemli sorunlardan biri de telif hakları sorunudur. tabii bu arada çocuklarımız ve öğrencilerimiz, internet kullanımı ile de daha da yaygınlaşan kes-yapıştıra dayalı tarih ödevleri hazırlama anlayışından uzak tutulmalıdır. onlara başkalarının emeklerine saygı göstermeyi öğrenme konusunda yardımcı olmalıyız. onları, intihal (plagiarism) konusunda da aydınlatmayı bir görev bilmeliyiz. teşekkür notu: georgia state Üniversitesi kütüphane uzmanı sayın tricia clayton'a teşekkürü bir borç bilirim. pek çok yayına onun yardımlarıyla ulaşabildim. kaynakça afzali, m.

was issued more than eighty years ago: public library of toronto. the rebellion of - : a bibliography of sources of in- formation in the public reference library of the city of toronto, canada (toronto: public library of toronto, ). broad though it was, that bibliogra- phy was restricted to works held by the library. it covered the rebellions of both lower and upper canada and included manuscripts and published material. it also dealt with the clerg y reserves and other political controversies that prompt- ed the rebellions as well as the aftermath, including the durham report of , the union of the canadas of , and the rebellion losses controversy of . the only published substantial survey of the historiography of the up- per canadian rebellion is also now very dated: j. e. rae, “rebellion in upper canada. ,” transactions of the his- torical scientific society of manitoba, se- ries , ( - ). rae evaluated major works, from the narratives of mackenzie ( ) and francis bond head ( ) to kilbourn’s biography ( ) and craig’s provincial history ( ). this bibliography, compiled from a great variety of sources, focuses on works specifically on upper canada. it lists, but does not attempt to evaluate, more than published writings and commentar- ies. undoubtedly there are many more, its last section ( ) lists a number of un- published graduate theses on rebellion related topics—again, there are surely others. thus additions and corrections are eagerly solicited and gratefully re- ceived (chrisraible@georgian.net). no attempt was made to list in- ternet websites—valuable as they are, they are both vast and ephemeral—and the search engines make them readily available. for example, a google search ( january ) for “’upper canada’ rebellion ” produced , pages, while “’patriot war’ ” produced , pages and ‘patriots’ war’ ” some , more. the bibliography is compiled in nine sections: bibliography of published works relating to the upper canada rebellion, -

difco laboratories, detroit, mi). in addition, mice were intraperitoneally injected with ng of pertussis toxin at and hours after immunization. clinical eae was assessed daily in a blind fashion using the clinical scoring system from : normal to : death as described previously. df treatment df (sigma-aldrich, st. louis, mo) was used in an emulsion of . % methylcellulose. for in vivo treatment, df solution was ad- ministered by oral gavage twice daily ( μg for g mice in μl volume), starting the day of eae induction until termination (day post immunization). the solution was prepared early everyday and stored at °c. mice receiving vehicle were used as controls. isolation of cns-infiltrating mononuclear cells and splenocytes to collect mononuclear cells (mncs), mice were extensively perfused at day post immunization with ice-cold phosphate buffered saline. for spleen cells, spleens were collected and dis- rupted in μm cell strainer before rbc lysis. to collect cns- infiltrating cells, brains and spinal cords were removed, thinly minced in liberase tl (roche, indianapolis, in), and incubated at °c for minutes. then, the cns was strained through a μm cell strainer, and mncs were enriched by centrifugation on a / percoll gradient for minutes at , rpm. splenocyte and lymphocyte culture and elisa experiments spleen cells were cultured in iscove modified dulbecco medium (gibco, gaithersburg, md) supplemented with % fetal bovine glossary df = dimethyl fumarate;

the number of infiltrating mncs in the cns of both df-treated and control groups. in addition to counting the total number of in- filtrating cells, we evaluated the immunophenotype of those cells by flow cytometry. the total number of cd + t cells and gm- csf+cd + t cells was dramatically decreased in the cns of the df-treated group (figure b).wealso looked at ifn-γ and il- incns-infiltratingcd +

observation that df suppresses gm-csf pre- dominantly in th cells, and to further evaluate the underlying mechanism of the suppressive effect of df on gm-csf, we investigated whether ifn-γ plays a role in this phenomenon. wt and ifn-γ–deficient splenocytes were cultured and stim- ulated with anti-cd / in the presence or absence of df. although df suppressed gm-csf–producing cd + t cells and gm-csf cytokines in the supernatant of wt splenocytes, the lack of ifn-γ abrogated the effect of df on gm-csf in cd + t cells. this finding implies that ifn-γ plays a crucial role in the suppressive effect of df on gm-csf (figure , a and b). df decreases th and gm-csf–producing th cells in human pbmcs to determine the best dosage of df in human in vitro experi- ments, we performed a proliferation assay and treated cells with , , and . μg/ml of df as described previously. based on our result, . μg/ml df had the least toxic effects on human pbmcs (data not shown). to evaluate the effect of df on human pbmcs, we cultured and stimulated pbmcs from healthy donors with human anti-cd / with or without df ( . μg/ml) for hours. cells were analyzed with flow cytometry after days, and multiple cytokines were measured by elisa in cell supernatants. for statistical analysis, we used the paired t test to compare pretreatment and posttreatment results. df treatment significantly reduced ifn-γ+cd + (th ) t cells, and elisa analysis of pbmc culture supernatants demon- strated that df significantly decreased ifn-γ production (figure c). in terms of gm-csf–producing cd + t cells, df sig- nificantly decreased gm-csf+ th cells with no effect on total gm-csf–producing cd + t cells, implying that the suppres- sive effect of df on gm-csf is mostly on th cells (figure d). discussion df was approved by the food and drug administration for the treatment of ms in , and its efficacy has been well demon- strated. during years of treatment, df reduced clinical relapse and lesion frequency while improving health-related quality of life in adults with rrms. , however, the underlying therapeutic mechanism of df is still under investigation. df has neuro- protective effects, , , including reducing spinal cord in- flammation and protecting myelin and neurons. , also, researchers who have studied the nrf transcriptional pathway and oxidative stress that df modulates , , found that both df and its active metabolite, monomethyl fumarate, induce the re- active oxygen species scavenger glutathione in oligodendrocytes, astrocytes, and hippocampal cells. , , other pathways have also been reported, including the hydroxycarboxylic acid receptor pathway and nuclear factor kappa-light-chain-enhancer of acti- vated b cells. , , df has been shown to promote th cytokine profiles, , , and transferring df-induced il‐ alowifn‐γlowil‐ +cd + t cells has demonstrated its therapeutic effect in eae. in patients with rrms after months of df treatment, the proportion of th cells was increased among memory t cells but with a decrease in the proportion of th and with no change in th cell proportion among memory t cells. another study, however, showed a decrease in cd + t cells producing ifn-γ, il- , and gm-csf, with no significant change in il- and il- after months. we also found that directadministration ofdf decreased proinflammatory cytokine production in the super- natant of human pbmcs obtained from healthy subjects. when we took a closer look at cd + t-cell subsets, df suppressed only gm-csf+th cells, but not gm-csf+th or gm-csfonly cd + t cells. one limitation of our study is that the human data are based on very small number of samples from healthy donors. further studies are necessary to confirm the effect of df on gm- csf–producing cells from patients with ms. although il- and ifn-γ are implicated in ms, mice still develop eae even in the absence of these cytokines. , pre- vious studies have shown that gm-csf secreted by cns- infiltrating t helper cells is essential for eae, even more so than il- or ifn-γ. lack of gm-csf or gm-csf receptor abrogates eae development, and adoptively transferred gm- csf–deficient th or th cells do not induce eae. we showed that df caused a decrease in gm-csf+ th cells in both the periphery and cns-infiltrating cells during eae, and given the fact that gm-csf–expressing cells are the crucial determinant of eae susceptibility and progression, one of the underlying therapeutic mechanisms of df appears to be through suppression of gm-csf+ th cells. in a variety of t helper cell populations, different transcription factors, including bhlhe , rorγt, t-bet, gata- , and stat , – are active at multiple time points. it has been reported that il- –activated stat promotes gm-csf gen- eration of cd + t cells, which differ from rorγt-, t-bet–, and gata- –promoted gm-csf–producing cd + t cells (sheng neurology.org/nn neurology: neuroimmunology & neuroinflammation | volume , number | july

however, a larger study in patients before and after df treatment is needed to validate current findings in ms. we also demon- strated that the suppressive effect of gm-csf is through the ifn- γ pathway. the molecular basis of the effects of df on gm- csf–producing t cells is unknown and merits further study. acknowledgment the authors thank katherine regan for substantive editing of the manuscript. study funding this work was supported by grants r ai and r ns from the nih. disclosure f. safavi, r. thome, z. li, g.-x. zhang, and a. rostami report no disclosures relevant to the manuscript. go to neurology. org/nn for full disclosures. publication history received by neurology: neuroimmunology & neuroinflammation november , . accepted in final form march , . references . herrero-herranz e, pardo la, gold r, linker ra. pattern of axonal injury in murine myelin oligodendrocyte glycoprotein induced experimental autoimmune encepha- lomyelitis: implications for multiple sclerosis. neurobiol dis ;

assessing patients with ankylosing spondylitis? abstracts a symptom). the health assessment questionnaire (haq) was used to measure func- tional status (scores – ). qol was measured by the mental (mcs) and physical (pcs) component summary scores of the short form- (sf- ). work/productivity loss was measured by the work productivity and activity impairment (wpai) instrument. comparisons were made between patients who currently use sc biologics versus those who discontinued treatment. results: of the , survey respondents ( % female; average age . years), ( . %) used sc biologics. the average dura- tion of ra was . years, with % reporting severe disease. the patient-reported mean scores were: morning stiffness . , fatigue . , pain . , haq . , mcs . and pcs . . patients reported . % work impairment and . % impairments in daily activity. patients who had discontinued sc biologic therapy (n , . %) reported signifi cantly worse scores in morning stiffness, fatigue, pain, and pcs (all p . ) versus patients currently treated with sc biologics (n , . %). patients who discontinued therapy had more work/activity loss; only activity impair- ment was statistically signifi cant (p . ). there was no signifi cant difference in haq scores between groups. conclusions: ra patients using current sc biolog- ics still suffer from serious impairments in symptoms, functional status, qol, and work/productivity. however, patients who discontinued sc biologic therapy have sig- nifi cantly worse symptom scores, physical functioning, and activity impairment com- pared with those currently being treated. both fi ndings indicate there is still an unmet medical need in ra patients. pms utility and quality of life of patients with osteoarthritis treated with the cyclooxygenase inhibiting nitric oxide donator (cinod) naproxcinod jonsson b , pfi ster p , holmstrom s , kobelt g uppsala university, uppsala, sweden, nicox, sophia antipolis cedex, france, nicox, sophia antipolis, france, european health economics, speracedes, france objectives: to estimate changes in quality of life (sf ) and utility (sf ) in patients treated with naproxcinod, naproxen or placebo for weeks, and to explore the effect of different disease measures on utility. methods: sf was available from international ph clinical trials in patients with knee or hip osteoarthritis comparing doses of naproxcinod ( and mg bid) to naproxen ( mg bid) and placebo. effi cacy was based on the pain, function and composite scales of the womac™ osteoarthritis index. co-morbidity measures included hypertension (ht) which increases with nsaid therapy, body mass index (bmi) and diabetes. changes in sf and individual sf domains were compared between the groups using anova and dunett’s -sided test. the effect of the womac™ indices, bp, bmi and diabetes on utility scores was explored using multiple regression analysis. results: all sf subscales except mental health as well as utility changed signifi cantly from baseline for all groups, and were correlated with changes in the womac™ indices (p . ). the change in the active groups was signifi cantly better than placebo for pain and physical function ( . ), but not signifi cantly different between treatments. however, absolute changes in utility, pain, physical function and general health were generally larger for naproxcinod mg than naproxen mg by around %. utility scores correlated signifi cantly with womac™, and patients with high bmi and bp or diabetes had lower utility scores and worse womac™ indices. increase in utilities were larger for patients with mg naproxcinod than for the other groups. conclusions: the slightly larger utility and quality of life changes with naprox- cinod mg despite a similar effect as naproxen on womac™ may be explained by a different side-effect profi le and a neutral blood pressure effect. pms an assessment of self reported outcomes in a nationally representative sample of elderly person diagnosed with rheumatoid arthritis rajpura jrjp j st. john’s university, fresh meadows, ny, usa objectives: to utilize webtv technology as a tool to measure hrqol in elderly persons having rheumatoid arthritis (ra) in a nationally representative sample and to describe their socio-demographic characteristics, medication use and other treat- ment choices. methods: a cross- sectional online survey research design. random digit dialing (rdd) survey procedures were used to draw a sample of elderly arthritic individuals from us households across states. a subsample of individu- als previously diagnosed with ra completed sf- v survey, as part of a larger study. eight sf- domain scores and physical and mental component summary (pcs and mcs) scores were computed and compared with cross-sectional norms for general us population. results: compared to the general population, our study sample per- formed poorly with respect to all the sf- domains except mental health (mh) and social functioning (sf) domains. ra is more prevalent in whites ( %) and males reported higher scores for all the eight sf- domains than females. about % of the sample reported the use of at least one available otc arthritic medication; % of the sample was taking prescription drugs, while about % reported having used natural/herbal remedies for arthritis. a signifi cant difference (p . ) was found between males and females with respect to only pcs scores. age was found to correlate negatively (p . ) with pcs and mcs summary measures, particularly for indi- viduals years and older. conclusions: webtv is an effective survey administra- tion tool for measuring hrqol. as expected, elderly perform poorly on three of the sf- domains (pf, rp, bp) having the most physical factor content. prescription drug use is fairly prevalent and use of otc medications and other forms of treatment is popular in the population under study. pms the effect of lifestyle choices on the risk of impairment in rheumatoid arthritis patients: an analysis of aerobic exercise and cigarette smoking shah a , plumb j , brawer r , tang b thomas jefferson university, philadelphia, pa, usa, centocor ortho biotech, inc, horsham, pa, usa objectives: through data analysis we will examine and identify the lifestyle factors that impact clinical outcomes of rheumatoid arthritis (ra) patients. methods: patients’ self-reported data was collected from the ra patient survey, an internet survey of ra patients. we studied the effects of aerobic exercise ( minutes a day per month), and cigarette smoking on ra patients. sign and symptom scores for morning stiffness, fatigue, and pain are defi ned from (no symptom) to (severe symptom) within the survey. the health assessment questionnaire (haq) was used to measure functional status scores ( – ). quality of life was measured by the mental component score (mcs) and physical component score (pcs) of the short-form (sf- ). productivity was measured by the work productivity and activity impairment (wpai) scale. there were no non-ra controls included in the study. results: a total of respondents were included in the analysis patients exercised and patients smoked cigarettes. the average age was . years and average ra duration was . years. patients’ mean mcs and pcs scores in the exercise ( . , . ) and non-smoking groups ( . , . ) were signifi cantly higher, than in the non- exercise ( . , . ) and smoking groups ( . , . ). overall work and productivity impairment was . % (exercise) versus . % (non-exercise), and . % (smoking) versus . % (non-smoking). signs, symptoms, and haq scores were signifi cantly better in the exercise and non-smoking groups (all p . ). conclusions: ra patients who exercise regularly have higher quality of life scores and clinical outcomes. those that smoke cigarettes have lower quality of life scores and higher symptom/ haq scores suggesting that this habit may be detrimental to their clinical outcomes. these results suggest that these lifestyle choices infl uence the overall risk of impairment in ra patients. pms is the health utilities index valid and responsive in assessing patients with ankylosing spondylitis? gooch k , feeny dh , wong r , pangan a , revicki d , van der heijde d abbott laboratories, abbott park, il, usa, kaiser permanente center for health research, portland, or, usa, abbott laboratories, parsippany, nj, usa, united biosource corporation, bethesda, md, usa, leiden university medical center, leiden, netherlands objectives: qalys are an important outcome used in cost-effectiveness analysis. the health utilities index mark (hui- ) is a self-reported measure covering attri- butes of health status. our objective was to assess construct validity and responsiveness of hui- in ankylosing spondylitis (as). methods: data were derived from the adalimumab trial evaluating long-term effi cacy and safety in as (atlas). we speci- fi ed a priori hypotheses regarding the direction and magnitude of associations expected between overall and single-attribute hui- scores and other health status and quality of life measures—sf- , asqol, bath as functional index (basfi), bath as disease activity index (basdai), and patient’s global assessment (pga). using baseline data, we calculated correlation coeffi cients and interpreted them via guidelines suggested by guyatt for negligible, weak, moderate, and strong associations. responsiveness was assessed by calculating standardized response means (srms) of hui- scores from baseline to week for patients meeting the minimum clinically important differences (mcid) for the asqol ( . ). responsiveness analysis was limited to patients with -week hui- scores. results: a total of of the patients enrolled in atlas were included in the analysis. mean age was years, . % were male, and mean duration of as was years. correlation coeffi cients between hui- scores and other instruments confi rmed . % of the a priori hypothesis, with an additional . % being under- or over-estimated by only one category. results of responsiveness analysis demonstrated that there were signifi cant differences in overall hui- (srm . ) and most single-attribute change scores for patients whose changes were greater than the asqol mcid vs. those whose changes were mcid. conclusions: these results suggest that hui- constructs are related to similar constructs in other measures, as expected. this study provides evidence of cross-sectional and longitudinal construct validity of the hui- for deriving utility scores for as patients. pms

objects, daily activities, pain/discomfort, and feelings) in people with self-reported osteoarthritis (oa), and to compare it with womac_hui , the utility derived from the standard disease-specifi c measure in oa. methods: data were collected from participants (age ) who completed questionnaires cat- d- qol in two waves and womac in one wave of a canada-wide online survey. to assess construct

growth daniel h. pletscher* and michael k. schwartz wildlife biology program, school of forestry, the university of montana, missoula, mt – , u.s.a. the proximate cause behind the decline of biodiversity is most often reduction or change of habitat and isola- tion of wildlife populations. in the western united states, as in much of the world, these problems can ultimately be attributed to increases in human population and per- capita consumption. this journal has published several articles concerning the burdens of human population growth (e.g., meffe ; gehrt ); indeed, we have not met many conservation biologists who are not firmly aboard the malthusian ship. we argue that population growth also burdens personal liberty by creating a need for greater regulation. parsons ( ) discussed the rela- tionship between population and liberty; we extend that argument to conservation. people unmoved on the pop- ulation issue with conservation arguments may be moved by our regulation argument. the problems faced by conservationists have changed. one hundred years ago, the predominant problem facing wildlife in north america was overexploitation. water- fowl, forest carnivores, and ungulates were exploited, largely for market, and were minimally regulated, to the point where most were near extinction. deer ( odocoileus virginianus ) populations were especially depleted and heading toward extirpation throughout the eastern united states. the american colonies began limiting hunting methods, seasons, and equipment in the mid- s to deal with overexploitation (trefethen ). passage of the lace act of , which made it a federal offense to trans- port illegally killed wildlife across state borders, further defined the public right to wildlife and helped curb over- exploitation. these regulations marked the beginning of the end of wildlife populations being considered unpro- tected public property. unregulated taking had exacted a lasting toll on some north american wildlife. for ex- ample, the passenger pigeon ( ectopistes migratorius ), which once flew in flocks of billions, was extinct by , largely because of unregulated taking of pigeons for mar- ket (blockstein & tordoff ). at about the same time, carnivores such as lynx ( lynx canadensis ) and moun- tain lions ( puma concolor ) were exploited to local ex- tinction in the northeastern united states (godin ). as the human population grew, wildlife conservation and management developed as an applied scientific disci- pline with a focus on reducing or controlling consump- tion by humans and increasing production of wildlife. specifically, the works of aldo leopold, particularly game management (leopold ) and “the upshot” (in a sand county almanac , leopold ), focused our attention on wildlife as a renewable but finite resource and halted our illusion of boundless wildlife populations. as conservationists we can be proud of our many suc- cesses. game species have rebounded, and predators— long maligned for their way of life—are making tremen- dous comebacks. mountain lions have returned to much of their former range in the western united states and are slowly returning in the east. the wolf ( canis lupus ) has gradually returned to the rocky mountains, and there is even an active campaign to reintroduce the grizzly bear ( ursus arctos horribilis ) to parts of its former range. the u.s. public has demonstrated through laws, regulation, and private actions that it values these species and their habitats, at least in certain places and times, more than competing human uses. our glaring failure, however, has been in treating the symptoms of wildlife conservation problems rather than their root causes. the world’s human population, currently approxi- mately billion, is growing ( births minus deaths) at a rate of people per second, or approximately , people each day (united nations ). natural resource managers must deal with this growth, and plant and ani- mal life must adapt or perish. what happens when we compromise in the conflict between wildlife habitat and the demands of more people? the trade-offs almost al- ways mean a net increase in the proportion of earth’s productivity allocated to human use and a net decrease in the proportion allocated to wild areas and wild life. the effect of humans on our environment is a func- tion of per capita consumption of resources times the number of people consuming those resources. in some cases we have done a fair job of convincing people to re- duce consumption and protect some habitat. if, how- ever, we reduce per capita consumption but the num- * email pletsch@forestry.umt.edu paper submitted january , ; revised manuscript accepted may , . conservation biology volume , no. , december pletscher & schwartz population growth ber of humans increases by similar or higher rates, what have we gained? in addition, if we protect some habitat but the human population increases by higher rates, what have we gained? we argue that we have lost: space per individual, wild species, and wild areas. in addition, by ignoring the population problem, we lose individual freedoms because of the need for increased regulation. for example, years ago, people in the western united states could harvest bison at any rate they wished. with an increased market and more harvesters, laws and regulations were enacted to stop overharvest (trefethen ). at the turn of the last century, people could dump their wastes into rivers with little noticeable effect. now, with an in- creased number of residents and more wastes per capita, laws and regulations are in place to maintain water quality. we examined the montana laws restricting fishing, hunting, and access to lands for these activities and found that in the general laws required only sections of code and pages of text (montana territorial legislature ; montana legislature ). today, montana has sections of code spanning pages of text (montana legislature ). population growth is not the only fac- tor causing increases in regulations, but we believe it to be the primary and most overlooked, factor. we continue to pass more laws and regulations to control both supply and demand in an over-taxed system; thus, our individual free- doms are inversely proportional to our population. one of our most basic freedoms is our reproductive freedom, but uncontrolled population growth leads to a reduction in all other freedoms, a tyranny of population growth. despite this tyranny, taking away reproductive freedom is not morally acceptable, socially feasible, or politically possible. what we can do, quite easily, is raise awareness that human population growth is the cause of most of our environmental ills and leads to increased regulation. few conservation issues are unaffected by human population pressures, and we must demonstrate these relationships. for instance, when talking about the effects of subdivided land on biodiversity, we can point out the root of the problem. when talking about problems of access on pri- vate lands or the institution of recreation fees, we can in- dicate why they are occurring. and when we discuss air- quality regulations that prevent open burning or require tougher industrial standards, we should discuss the ulti- mate root of the problem. the tradeoffs should be identi- fied explicitly. increased human population equals in- creased pressure for regulation. furthermore, we must not only preach to the converted. these messages should be delivered to groups outside the society for conserva- tion biology, especially to those people who traditionally are uninterested in the outdoors but who have an interest in seeing government reduced. in other words, if popula- tion growth is the primary culprit hindering the conserva- tion of biodiversity, we should not stop short of enlisting political groups who are interested for different reasons. let conservation make strange bedfellows. we must continue to encourage a reduction in con- sumption and work on increasing efficiency on those lands producing goods and services. we must also con- tinue to encourage shared uses of our wild lands and nat- ural resources. but if this is all we do, we will continue to tinker while our wildlife legacy is lost. we must point out to anyone who will listen—and to recognize ourselves— that human population growth is a grave threat to indi- vidual freedom and to all that we as conservationists hold dear. there are no easy answers, but education is a start. thomas jefferson, the third american president and framer of the u.s. constitution, argued that it is the re- sponsibility of the current generation to undertake ac- tions that will maintain the freedom of the next genera- tion. by ignoring the population issue, we not only lose our valuable wild areas and wild life, but we infringe on the freedoms of the next generation. the earth belongs to each of these generations during its course, fully and in its own right. the second generation receives it clear of the debts and encumbrances of the first, the third of the second, and so on. for if the first could charge it with a debt, then the earth would belong to the dead and not to the living generation. thomas jefferson ( ) ( foner : ) acknowledgments we thank j. w. thomas, g.

be found in additional information at the end of the article abstract introduction previous studies have shown that risk attitudes and tolerance for uncertainty are significant factors in clinical decision-making, particularly in the practice of defensive medicine. these attributes have also been linked with rates of physician burnout. to date, the risk profile of emergency medicine (em) physicians has not yet been described. our goal was to examine the risk profile of em residents using a widely available risk tolerance and attitude assessment tool. methods first-, second-, and third-year residents of thomas jefferson university hospital’s em residency program completed the commercially available, unmodified risk type compass, a validated instrument offered by multi-health systems (mhs inc, new york, usa). scored reports included information on residents’ risk type (one of eight personality types that reflect their temperament and disposition); risk attitudes (domains where residents are more likely to engage in risky behaviors); and an overall risk tolerance indicator (rti) (a numerical estimate of risk tolerance). rti scores are reported as means with % confidence intervals (cis). results there was no significant change in rti scores in residents across different years of their post- graduate year (pgy) training. pgy-one residents trended towards risk aversion; pgy-two residents were more risk-taking; and pgy-three residents scored in the middle. conclusion our pilot assessment of risk types in em residents highlighted shifts across the years of training. variations between members of each pgy cohort outweighed any outright differences between classes with regards to absolute risk tolerance. there was an increase in the frequency of health and safety risk-taking attitude with higher pgy class, and this was also the risk attitude that was the prominent domain for resident risk tolerance. the study was limited by sample size and single cross-sectional evaluation. categories: emergency medicine, medical education, other open access original article doi: . /cureus. how to cite this article rodriguez c, rahman n a, london k, et al.

risk, risk tolerance, wellness, risk attitude, risk type, emergency medicine, graduate medical education introduction despite significant advances, healthcare remains a field steeped in uncertainty and ambiguity. there are intrinsic risks whenever any management plan is executed. these risks pose even graver challenges in emergency medicine (em), where uncertainty intersects with patient acuity and patient volume. while high-risk decisions and management are replete in the practice of em, the risk profiles of em providers, particularly those in training, have not been assessed by prior studies. knowledge of risk-taking tendencies may be critical in advising and developing physicians in training. em providers with substantial risk aversion may subject their patients to unnecessary testing, such as advanced diagnostic imaging [ ]. these providers may also be more likely to admit their patients or highly utilize observation units [ ]. in addition, cognitive biases and personality traits (i.e., omission bias, tolerance to risk, and/or overconfidence) may lead to diagnostic inaccuracies and medical errors resulting in mismanagement or inadequate resource utilization [ ]. it is imperative that providers reflect on their individual risk tolerances. given there is no clear understanding of what ideal risk aversion or risk tolerance should be in em residents, it is prudent to first identify a baseline risk profile for this group. while several studies have identified methodologies for assessing risk-taking behaviors and attitudes, they are not specific to em physicians. to date, previous studies in this area have not utilized standardized assessments; consequently, cross-study comparisons still remain a difficult challenge. the solution may be found by seeking guidance from other disciplines. studies have demonstrated improved attitudes toward team building, communication, and adverse event recognition after having clinical teams from various disciplines (i.e., em, surgery, nursing) complete coursework in crew resource management (crm) [ - ]. crm can easily be applied to em providers, as they naturally work in teams immersed in high-stakes situations while managing fatigue, communication, and decision-making. risk tolerance has been heavily studied in business, where risk attitudes are essential to employee recruitment, coaching, and strategic planning. risk attitudes and their subsequent effects on entrepreneurship [ - ], small businesses [ ], investments [ ], and role conflict [ ] have also been studied. using a validated risk assessment tool can be of potential benefit when assessing professionals across various fields and specializations. the risk type compass (rtc), created in by the psychological consultancy ltd (tunbridge wells, united kingdom), provides multiple modes of risk assessment [ ]. our pilot study aimed to describe the risk type and risk tolerance of em residents in our three post-graduate year (pgy) cohorts. we hypothesized that em residents would tend to have a higher risk tolerance when compared to the general population, in line with existing ‘cowgirl’ and ‘cowboy’ stereotypes. additionally, we hypothesized that risk tolerance would increase with the increasing pgy. materials and methods study instrument the rtc is a commercially available psychometrically validated assessment tool (multi-health systems, new york, usa, ). the standard rtc questionnaire, which consists of two parts, is a -item assessment: items that determine risk type, items that determine risk attitude, and items for validity. it includes a self-report with a six-point likert scale for part rodriguez et al. cureus ( ): e . doi . /cureus. of one, and a three-point rank ordering for part two. for this pilot, the complete version of the questionnaire was used with official individualized scoring from rtc through multi-health systems (mhs) in the form of a personal report. the rtc uses a normative sample of , adults ( sample). this particular evaluation has proven to have notable internal consistency, with α values greater than . . total rtc scores were computed by mhs software. for this pilot study, we used the rtc-generated personal report, which is not professional- or industry-specific. the rtc offers several measures. ‘risk type’, analogous to the eight personality types, is one such measure. risk types include: wary (i.e., self-disciplined and cautious), prudent (i.e., self- controlled and detailed), deliberate (i.e., systematic and compliant), composed (i.e., cool- headed and optimistic), adventurous (i.e., impulsive and fearless), carefree (i.e., spontaneous and unconventional), excitable (i.e., uninhibited and excitable), and intense (i.e., pessimistic and self-critical). risk type correlates to a spectrum for one’s relationship with risk, from risk- averse (i.e., wary) to risk-tolerant (i.e., adventurous). the second measure is the ‘risk attitude’, which includes five sub-scales of risk tolerance across the different domains of one’s life. risk attitudes include: financial (i.e., willingness to take financial risk), social (i.e., risk of embarrassing oneself or others and risking disapproval), health and safety (i.e., being alert to dangers that may impact one’s current or future health state), recreational (i.e., possibility of physical danger and its influence on decisions regarding recreational activities one engages in), and reputational (i.e., morality and a readiness to live life according to accepted principles). finally, the risk tolerance index (rti), an overall numerical estimate of tolerance for risk based on risk type and risk attitude, is calculated by combining the two measures. rti ranges from zero (low risk tolerance) to (high risk tolerance). study design and participants this cross-sectional investigation was conducted at an urban em residency training program. study recruitment included em residents ( pgy-one, pgy-two, and pgy-three residents) at a single academic medical institution, thomas jefferson university hospital in philadelphia, pennsylvania. there were no exclusion criteria for participation. the rtc was deployed electronically in august . residents completed an electronic consent form followed by a demographics questionnaire including age, gender, and level of residency training. rti scores are reported as means with % cis. differences in risk tolerance based on pgy- training level were assessed. an analysis of variance (anova) was used to evaluate differences across means. study investigator dp has had exposure to mhs products through graduate-level doctoral studies, and primarily assisted with rtc score interpretation. this study was previously presented as a poster at a local symposium (poster: rahman n, papanagnou d. an evaluation of risk attitudes and risk tolerance in emergency medicine. college within the college (cwic) posters; november , ). the study was reviewed and received approval from the institutional review board of thomas jefferson university (# e. ). results pgy-one em residents gravitated towards the risk averse part of the spectrum. pgy-two and pgy-three residents were noted to cluster at both (i.e., risk-averse and risk-tolerant) ends of the risk-type spectrum (figure ). rodriguez et al. cureus ( ): e . doi . /cureus.

article was to describe the risk type and risk tolerance of em residents by using the risk type compass, a commercially available risk tolerance assessment tool. the rtc tool specifically focused on differences in how individuals perceive, react to, and manage risk, as well as how they make decisions when risk is involved [ ]. a significant difference in rti scores across years in training was not observed. while there were noted preferences for risk type by pgy class in our cohort, however, rti, as a measure for risk tolerance, cannot be used to fully appreciate the nuances in changes in risk type across residents. examination of resident risk attitudes is useful for identifying in which domains residents were more comfortable with risk-taking behaviors. this was most distinctive amongst pgy-three residents, who were most risk tolerant when it came to their own health and safety. furthermore, ‘health and safety’ was one of the most commonly delineated risk attitudes for the highest risk tolerance, with increasing frequency from pgy-one to pgy-three residents. while definitive conclusions are limited in our study, the evaluation of one's relationship with risk and tolerance for uncertainty in the clinical setting has the potential to offer valuable insight into trainee performance. previous studies have linked tolerance for uncertainty with burnout in both emergency medicine physicians and residents. kuhn et al. reported that poor tolerance for uncertainty, secondary to concerns for bad outcomes, is strongly correlated with emotional exhaustion and/or burnout in em physicians [ ]. another study by takeyesu et al. found that residents with higher levels of burnout were significantly less tolerant of uncertainty when it came to clinical decision-making. the authors also reported that uncertainty may serve as a source of anxiety and psychological stress, which may ultimately negatively affect clinical performance and delay informational recall, which collectively can inhibit optimal learning [ ]. in light of these findings, directly addressing areas of uncertainty during residency training may be helpful in supporting em residents as they build their clinical skills and develop their rodriguez et al. cureus ( ): e . doi . /cureus. of resilience to protect them from burnout. additional studies applying the rtc risk assessment may be of use, especially when applied to cohorts longitudinally to assess potential shifts in risk tolerance over the course of their residency training. such findings would offer insight into interventions that can impact education and training; wellness and burnout; and clinical decision-making. a potential opportunity for further investigation would be to include an objective measure for burnout, such as the physicians’ reaction to uncertainty (pru) scale [ ], to draw conclusions about the relationship between risk tolerance and burnout in specific cohorts of trainees. while our study suggests several trends, it was hindered by the small sample size of only em residents from a single institution. subsequent follow-up studies to this pilot should be adequately powered to note any differences in risk patterns. the study also represents a single snapshot of residents over the course of their training. it is possible that randomness in recruitment may impact trends between classes, where findings may actually represent differences in individual personalities, rather than effects based on training level. moving forward, our study should be replicated with more em residents across multiple institutions and repeated over the course of their training, in order to build a more robust and actionable risk profile. conclusions risk type and tolerance inevitably affect patient care in the em setting. further research is needed to determine the ideal risk profile that allows for reduction in wasteful expenditures and defensive medicine without negatively impacting patient care. this data could also help inform curricular training and identify residents who may benefit from targeted wellness interventions. our pilot study supports the notion that risk type and risk tolerance are aspects of provider personality worthy of additional scholarship. additional information disclosures human subjects: consent was obtained by all participants in

lb pharmecon as, asker, norway objectives: to elicit similarities and differences in the poli- cies and practices for financing, pricing and reimbursing pre- scription drugs in the often perceived similar nordic countries of denmark (d), finland (f), norway (n) and sweden (s). methods: a review of the four countries’ authorities’ stated policies and practices on the matter were performed through a search of the literature and of the respective authorities’ home- pages. the information was validated through interviews with key personnel of the reimbursement agencies in each country, and the final study reports for the respective countries were reviewed by the same persons. results: all countries have a national health care system financed by taxation. there are dif- ferences in the reliance upon patient co-payment (n %, others – %) and whether financing is a county (s) or national (others) responsibility. all have regulated prices for reimbursed drugs; based either upon international comparisons (n, d) or country-specific decisions (s, f). the criteria used for deciding to reimburse a drug vary between the countries, and reimbursement is practiced differently in several other dimensions: mandatory requirement for pharmacoeconomic analysis (f, n, s), the existence of patient-specific reimbursement systems (d, f, n), product- (s) or indication-based (others) reimbursement, use of graded (f), conditional (n, s) or temporary (s) reimbursement, use of reimbursement contracts (n), and different processes for handling disagreement about decisions. conclusion: the nordic countries all have a national health care system financed by taxation and encompassing prescription drugs, but differ in a number of other dimensions with respect to financing, pricing and reimbursing such drugs. php a systematic review of the european pharmaceutical market and the impact of european union regulation and jurisdiction van ginneken ej, schreyögg j, gericke ca, busse r berlin university of technology, berlin, germany objectives: to examine the impact of the increasing role of the european union (eu) on the european pharmaceutical market, focusing on industry and national policies. to give a sys- tematic overview of the current state of the european pharma- ceutical market as a whole. methods: systematic literature review for the years – , including “grey” sources of information, online databases, european commission docu- ments and european court of justice rulings, relevant journals and systematically tracing back relevant references. results: the eu attempts to liberalise the pharmaceutical market and the realisation of a single european market (sem) came to a stand- still, after some considerable achievements (e.g. marketing authorisation). instead, the eu seems to concentrate on coor- dination of results through the adoption of the so-called g recommendations. eu member states successfully—and inten- tionally—kept control on the issues of pricing, reimbursement, pharmacies and prescribing. over the last years they adapted increasingly convergent measures to cope with rising pharma- ceutical expenditures, without long-lasting cost containment effects. however, recent european case law might prove to have far reaching consequences on the provision of medicines. the european pharmaceutical industry—although profitable—is underperforming compared to the usa, which is blamed on restrictive regulatory frameworks in the member states. con- clusions: the future of the actors in the european pharma- ceutical market is not clear. will it bring more european influence or a strengthening of national influence? in the short term, major change towards a sem seems unlikely, but in the longer term european history showed that major change is pos- sible. it seems clear that much depends on the attitude of member states towards the new approach and the interpretation and influence of european case law. for the european industry, adoption and implementation of g recommendations is of great importance for future competition with us-based companies. php using an italian population database to profile prevalence and costs of chronic conditions yuen ej, maio v, louis dz, rabinowitz c, robeson m, smith kd jefferson medical college, thomas jefferson university, philadelphia, pa, usa objective: individuals with chronic medical illness may have multiple health problems, and are often costly and difficult to manage. this study identifies those with highly prevalent chronic conditions and assesses related health service use and costs in the population of emilia romagna (rer), a large northern italian region. methods: pharmaceutical, hospital, and demographic data from and have been assembled for the entire population of rer ( million). pharmaceutical and hospital tariffs were a proxy for costs. pharmacy and hospital records were used to identify individual morbidity. data included demo- graphic and geographic information, encounter dates, diagno- sis/procedure codes, pharmaceutical information, and health care costs. individuals were classified as having a chronic condi- tion in , and we examined pharmacy and hospital use/costs in . descriptive analyses compared mean and total costs, as well as proportions within the population. results: we iden- tified five highly prevalent chronic conditions: cardiovascular dis- eases (n = , , . % of the population); rheumatologic conditions (n = , , . %); gastric acid disorders (n = , , . %); chronic respiratory illnesses (n = , , . %); and psychiatric disorders ( , , . %). . % of the population had one or more of these five chronic conditions, and these individuals accounted for . % of the pharmacy costs and . % of the hospital costs in the following year. for persons with these five conditions, we also described use and costs by age and gender, residence, and income. conclusions: interest- ingly, one-fourth of the population with selected chronic condi- tions accounted for large proportions of cost and use of health services. the ability to identify those with chronic conditions would help planners and governmental agencies to address health care needs, increase quality of care, avoid unnecessary hospitalizations, and save costs. these types of data can be used to estimate health care financing and risk adjustment models, and profile specific clinical, demographic or geographic sub-groups. php adherence index of performance—a new method and tool for ongoing evaluation of medication adherence improvement initiatives day

land use may discourage active investment in timber production, thereby reducing future timber supply. in this study, we examine the potential effects of population growth on timber production using a two- step approach. first, we compare expert opinions on where forests will not be managed as commercial timberland with population density in these areas, and test for a relationship between the two. then, we use the relationship between population density and likely timber management to adjust timber inven- tories for population effects. the study provides i n s i g h t s i n t o t h e s e i m p

classification of potential commercial timberland (pct) and several factors describing the accessibility and operability of the site and the population density of the area. that is, we posited that the probability of land (l) being labeled as pct is given as: pr(l = pct) =f(xi) = - f(g[x]) ( ) where f is a cumulative distribution function which depends on a function (g) of a vector of explanatory variables (x). we assumed that f had a logistic form which is a close approximation to the normal distribu- tion. the resulting ‘logit’ model has the following form: pr(l = pctix) = - f(g[x]) = eitcxj ( ) the vector x includes the following variables: the p o p u l a t i o n d e n s i t y o f t h e a r e a ( p o p , p e o p l e p e r s q u a r e mile), site index (si, height. at

recognition of the need for relevant research in the primary care setting to improve patient and population outcomes, and family physicians are uniquely poised to conduct such research because they provide the largest volume of health care of any single specialty (nearly million patient visits annually). despite this acute awareness and need, research remains a particular challenge to the

initiatives. research advocates and governmental organizations, particularly the national institutes of health, should increase the funds available to support a primary care research agenda to enable

children’s hospital, boston, massachusetts, usa dr. eileen l. randall was an accomplished clinical microbiol-ogist when the field was still developing its identity. as her colleague and friend dr. josephine morello recently said, “eileen randall was a distinguished clinical microbiologist even before most microbiologists knew what clinical microbiology was. she was in the forefront of this nascent field, widely imparting her vast knowledge of infectious microorganisms.” her contributions in- cluded research in bacteriology, the clinical care that her labora- tories performed, and, perhaps foremost, her educational work and mentorship of clinical microbiologists. dr. randall received her b.s. in medical technology from ohio state university in . she attended graduate school in micro- biology at the jefferson medical college in philadelphia, pa. her master’s dissertation was titled “studies on the morphology, phys- iology, and immunology of endamoeba histolytica, endamoeba coli, and endamoeba invadens.” her ph.d. work was done with the guidance of dr. henry stempen. dr. randall turned from parasi- tology to bacteriology, which remained her primary area of re- search throughout her life. she completed her ph.d. in , on “studies on mima-like and herellea-like organisms.” after her studies, dr. randall became director of the microbi- ology laboratory at thomas jefferson university hospital and was appointed in the departments of microbiology and pathology. in , she became director of the microbiology laboratory at evanston hospital. she rose to become professor of pathology at the northwestern university feinberg school of medicine and senior attending in medicine at evanston hospital. mr. richard gottschall, who was manager of microbiology at evanston hospi- tal, said “because she started as a bench-level technologist, she always had a profound understanding of the issues facing the techs published ahead of print august copyright © ,

board of education and training, and the foun- dation for microbiology lecturer series ( ). dr. randall was the secretary of the eastern pennsylvania branch of the asm from to , and she was on the steering committee in when the clinical microbiology section was formed in the eastern penn- sylvania branch ( ). she directed and participated in many work- shops and symposia in the clinical microbiology branch. dr. ran- dall was also the president of the illinois society for microbiology. chief among dr. randall’s contributions were those in educa- tion. she started a master’s degree program in clinical microbiol- ogy in philadelphia, pa. dr. james poupard recalls, “she applied all her talents of persuasion to convince faculty and administra- tion of the thomas jefferson university graduate school to estab- lish a program. it was a big struggle on her part, but she finally got approval in august of , just month before classes were to start. the program was a complete success and had a significant effect on the quality of clinical microbiology in philadelphia.” dr. randall and dr. morello taught a traveling workshop on staphy- lococci and streptococci sponsored by the asm, and dr. morello recalls, “many times. . . the days would be prolonged, because she invariably got caught up in answering questions about any topic of diagnostic microbiology raised by the attendees.” dr. randall was a mentor to those interested in clinical micro- biology. dr. gary doern recalls that when he knew her, early in his career, “she was not only an extraordinarily gifted clinical micro- biologist; she was generous in spirit, full of enthusiasm and a truly wonderful teacher. indeed, i cannot remember a single instance when we were together that she didn’t teach me something.” dr. paul schreckenberger says, “dr. randall befriended me when i first arrived to work at the university of illinois chicago in . she encouraged me (actually pushed me) to go back to graduate school and get my ph.d. degree because she always felt that i had the calling to be a laboratory director. eileen was proud as a parent when i fulfilled my dream of becoming a laboratory director.” dr. randall published over articles, mainly in clinical bac- teriology. her early work included extensive analyses of the bio- chemical characteristics of clinical isolates of members of the mi- mae tribe (now reclassified), which included bacteria that mimic the morphology of neisseria in clinical specimens. biochemical identification of organisms was a lasting interest, and one of her later publications is an evaluation of a system for identifying en- terococcus. dr. randall published a series of studies on improving and validating methods of blood culture and articles on detection of pharyngeal streptococcus pyogenes. these papers emphasize the clinical utility of the methods, but they are also striking for their careful analysis of laboratory concerns, including ease of use, workflow, and instrument requirements. her achievements and contributions were recognized with sev- eral awards ( ). she received the distinguished alumni award from thomas jefferson university, graduate school of biomedi- cal sciences, in . this award “focuses on the professional ac- complishments of alumni and helps to foster communication be- tween current and former graduate students.” her professional accomplishments were recognized with the significant contribu- tors to clinical microbiology award from the south central as- sociation for clinical microbiology in and the pasteur award from the illinois society of microbiology in . dr. randall was an important voice in shaping the field of clinical microbiology. dr. randall passed away on december , , after a long illness that she met with courage. her early death was a great loss to her colleagues, friends, and family. she left an important legacy through her impact on our field. dr. tom thompson, who was a student and friend of dr. randall, said, “the commitment and passion that we in clinical microbiology have today has flowed, in large part, from dr. randall’s career and life. she was smart, compassionate, unselfish, fair, loyal and fiercely dedicated. when i look at our profession today, that is what i see.” acknowledgments dr. tom thompson generously provided biographical information

acknowledgments references © macmillan magazines ltd the thomas jefferson paternity case the dna analysis of y-chromosome haplo- types used by foster et al. to evaluate thomas jefferson’s alleged paternity of eston hemings jefferson, the last child of his slave sally hemings, is impressive. how- ever, the authors did not consider all the data at hand in interpreting their results. no mention was made of thomas jeffer- son’s brother randolph ( – ), or of his five sons , . sons of sally hemings con- ceived by randolph (or by one of his sons) would produce a y-chromosome analysis identical to that described by foster et al. further collaborative data (for example, the whereabouts of any of those who might have been involved at conception) are needed to confirm that jefferson did indeed father his slave’s last child, as claimed in the title. we know thomas jefferson was there, but how about randolph jefferson and his sons? david m. abbey health science center, university of colorado, teakwood court, fort collins, colorado , usa e-mail: dabbey @aol.com if the data of foster et al. are accurate, then any male ancestor in thomas jefferson’s line, white or black, could have fathered eston hemings. plantations were inbred communities, and the mixing of racial types was probably common. as slave families were passed as property to the owner’s off- spring along with land and other property, it is possible that thomas jefferson’s father, grandfather or paternal uncles fathered a male slave whose line later impregnated another slave, in this case sally hemings. sally herself was a light mulatto, known even at that time to be thomas jefferson’s wife’s half sister , . gary davis evanston hospital, ridge avenue, evanston, illinois , usa foster et al. reply — it is true that men of randolph jefferson’s family could have fathered sally hemings’ later children. space constraints prevented us from expanding on alternative interpretations of our dna analysis, including the interesting one proposed by davis. the title assigned to our study was misleading in that it repre- sented only the simplest explanation of our molecular findings: namely, that thomas jefferson, rather than one of the carr broth- ers, was likely to have been the father of eston hemings jefferson. it had been suggested to us earlier (by herbert barger, who also helped to recruit the descendants of field jefferson who par- ticipated in our study) that isham jefferson, son of thomas jefferson’s brother ran- dolph, might have been the father of one or more of sally hemings’ children. barger’s proposal was based on a statement that isham was reared by thomas jefferson; he suggested that isham could have been at monticello or at snowden (snowden was across the james river from scottsville, which is about miles from monticello) when eston hemings was conceived. but it is not known for certain that isham was at monticello at that time, whereas it is docu- mented that thomas jefferson was. from the historical knowledge we have, we can- not conclude that isham, or any other member of the jefferson family, was as likely as thomas jefferson to have fathered eston hemings. we know from the historical and the dna data that thomas jefferson can neither be definitely excluded nor solely implicated in the paternity of illegitimate children with his slave sally hemings. when we embarked on this study, we knew that the results could not be conclusive, but we hoped to obtain some objective data that would tilt the weight of evidence in one direction or another. we think we have provided such data and that the modest, probabilistic interpretations we have made are tenable at present. e. a. foster*, m. a. jobling†, p. g. taylor†, p. donnelly‡, p. de

same body size and aero- bic power. volume densities of mitochon- dria in leg muscles are similar to those of mammals of the same size and aerobic capacity, whereas those in the relatively inactive flight muscles are only half as large and correspond to values reported for less aerobic mammals (table ). given that % of the rhea’s body mass consists of leg musculature, rates of oxygen uptake by mitochondria per millilitre dur- ing locomotion at the aerobic maximum appear to fall within the range reported for mammals. capillary densities in the rhea leg and flight muscles, like the mitochon- drial volume densities, also parallel values reported for the muscles of athletic and less mobile mammals. in contrast to the apparent conservation of structure–function relationships in most of the respiratory system, our results sug- gest that there are basic differences in the performance of the lungs of birds and mammals. we could not measure the lung volumes of the rheas directly, but in birds these are normally slightly more than half of those of mammals of the same mass , . the rheas therefore achieved maximum oxygen flux rates, equal to those of the most aerobic mammals of their size, using lungs that are probably only half as large. this supports the general belief that avian lungs provide relatively more function per unit volume than mammalian lungs , . although the aerobic limits of rheas and athletic mammals are similar, the metabolic power available in practice, and their func- tional needs, are not. unlike dogs, horses and other athletic mammals that sustain high metabolic rates for hours during pre- dation and migration, rheas do little or no sustained running and are poor at dissipat- ing metabolic heat loads . rheas have apparently not been under strong selective pressures like those that promoted the aero- bic power of extant running mammals. large flightless birds lead fairly inactive lives, and may have lost the ability to fly primarily because of a lack of predation. why rheas have an aerobic power that greatly exceeds their apparent functional needs remains a puzzle. matthew w. bundle*, hans hoppeler†, ruth vock†, june m. tester*, peter g.

lebard , annika f. barber , michael l. klein . temple university, philadelphia, pa, usa, yeshiva university, new york, ny, usa, thomas jefferson university, philadelphia, pa, usa. the most likely targets for volatile anesthetics (va) are ion channels. the mechanism of volatile anesthetic action is not completely understood. identify- ing the molecular pathway for drug binding is crucial to understand the effect of va on voltage gated sodium channels. we use molecular dynamics simula- tions to identify the binding sites for a hydrophobic general anesthetic isoflur- ane, on voltage gated bacterial sodium channel nachbac. apart from the voltage sensing domain (s -s ), linker and the pore domain (s -s ), bacterial sodium channels also have fenestrations, which provide a hydrophobic tunnel through the lipid-embedded portion of the channel to the central cavity, where the known local anesthetic site is located. unbiased ‘‘flooding’’ simulations were performed on the activated open confirmation of nachbac. we per- formed a cluster analysis to identify all the possible binding sites of isoflurane. the three most important ones among them are: a region near the selectivity filter, called the extracellular site, a region near the s -s linker, called the linker site, and a region within the cavity, called the cavity site. the most important observation is that isoflurane enters the central cavity through the fenestrations. free energy perturbation method was employed to calculate the binding affinities of isoflurane for each of these sites. we also studied the interactions between isoflurane and the amino acids in these three binding sites. -pos board b a key gating charge interaction required for slow inactivation of the navab bacterial sodium channel tamer m. gamal el-din, todd scheuer, william a. catterall. university of washington, seattle, wa, usa. bacterial voltage-gated sodium (nav) channels are considered an ideal model for structure-function studies. the elucidation of the crystal structure of the bacterial channel navab (payandeh et al., nature , - , ) opened an avenue to understand electrical signaling in excitable cells at the structural level. navab expressed in hi insect cells as for structural studies has unusually negative voltage-dependent activation (va ~ mv). navab also has three phases of inactivation, a biphasic early inactivation process (t ~ ms, t ~ . s, at � mv) followed by an unusually strong and use-dependent slow-inactivation process. to search for the molecular basis for negative activation and slow inactivation of navab, we mutated the outer- most gating charge partner in the s segment, asn , to lys. this mutation shifted the activation curve ~ mv toward more positive potentials. surpris- ingly, it also completely abolished use-dependent slow inactivation. we showed previously that the equivalent residue in nachbac (asp ) interacts with the r gating charge in the s segment during activation using the disul- fide locking method (decaen et al, pnas ( ) - ). to test whether this interaction between r and n was critical for slow inactivation, we mutated navab r to cys. the resulting mutant navab_r c also had positively shifted channel activation (þ mv) and no use-dependent slow inactivation. the fact that these reciprocal mutations have the same functional effects suggests that interaction between r in the s segment and n in the s segment is an important link that stabilizes the activated state of the voltage sensor and triggers the slow inactivation process. -pos board b computational study of the prokaryotic sodium channel karen m. callahan, benoit roux. university of chicago, chicago, il, usa. ion-selective voltage-gated ion channels allow ions of a specific element or set of elements to pass, but exclude other ions. recently, the crystal structure of navab was published (payandeh et al ( ) nature , ), giving an un- ambiguous picture of the structure of the sodium channel selectivity filter (sf) of the prokaryote arcobacter butzleri. the filter is much wider than that of the narrow, carbonyl-lined potassium channels, allowing ions to penetrate with minimal dehydration, multiple pathways, and even to pass each other. previous computational studies have attempted to explain sodium selectivity, and claimed consensus (corry and thomas ( ) jacs , , furini and domene ( ) plos , e ). experimental ion selectivity determina- tion from pore-only constructs of a sodium channel with the same sf sequence shows stronger ion selectivity from reversal potential than from the ratio of the fluxes of sodium and potassium (shaya et al ( ) pnas , ), but selectivity, na þ/kþ, was still less than five. simulations based upon the closed-pore crystal structure could not determine selectivity directly from con- duction. to investigate this issue, we first calculated multi-ion potentials of mean force in the selectivity filter of pore-domain-only navab with an ex- tended equilibration period, and a replica-exchange molecular dynamics scheme, which allows for improved sampling. we then explored the non- equilibrium conduction of sodium and potassium in the presence of an applied electric field through a model navab pore truncated to mimic the conformation of the open pore. we also present multi-ion pmf calculations to illustrate similarities and differences between this model and the intact pore. when taken together, these two methods provide complementary views of ion selectivity and conduction based upon the conformation of the navab crystal structure of payandeh et al ( ). -pos board b volatile general anesthetic interactions with a bacterial sodium channel annika f. barber , srinivas g. raju , david lebard , vincenzo carnevale , michael l. klein , manuel covarrubias . thomas jefferson university, philadelphia, pa, usa, temple university, philadelphia, pa, usa. general anesthesia results from complex interactions involving ion channels in the brain. voltage-gated ion channels are modulated by halogenated inhaled general anesthetics, however the drug-channel interactions are generally believed to be non-specific making it difficult to investigate the molecular mechanisms of anesthetic action. we find, however, that the bacterial sodium channel nachbac exhibits differential regulation by different general anes- thetics, suggesting that there may be specific interactions. molecular dynamics (md) simulations have identified several possible binding sites for isoflurane in the nachbac channel structure. here, we have characterized the affinity, occu- pancy and hydrogen bonding for these sites and identified key interactions. in addition, experimental evidence suggests that both isoflurane and sevoflurane have dual actions on nachbac, possibly involving action at two different sites. consistent with pore block, sevoflurane accelerates the decay of the current ( % faster at . mm sevoflurane) but, at the same time, increases the peak current ( % increase with . mm sevoflurane), which argues against the blocking mechanism. we hypothesize that an additional mechanism involving a distinct site is necessary to explain the latter effect. we are currently employ- ing md simulation and structural modeling combined with mutagenesis and electrophysiology to test this two-site hypothesis and investigate the molecular mechanisms of these opposing effects. supported by ninds f ns (afb) and nigms p gm (mlk). -pos board b polymodal, high affinity actions of m-conotoxins on a bacterial voltage- gated sodium channel rocio k. finol-urdaneta , robert glavica , jeff r. mcarthur , robert j. french . university of calgary, calgary, ab, canada, rmit, melbourne, australia. m-conotoxins (mctxs) are potent blockers of eukaryotic sodium channels, and individual members of the mctx family are highly specific for particular nav isoforms. we have begun to explore mctx interactions with nachbac, a pro- karyotic nav channel closely related to navab, whose crystal structure was re- cently determined (payandeh et al, , nature : ). our data reveal actions on both ion conduction and gating, consistent with polymodal actions on the pore domain. under voltage clamp, whole-cell currents from nachbac expressed in tsa- cells were reduced, up to nearly complete block, by concentrations in the pm to mm range, for wildtype toxins and derivatives of mctx piiia and kiiia. for wildtype piiia, dose-response data ( . - , nm) yielded the following: ic = . nm; maximal fraction of current blocked = . ; hill coefficient = . . chen & chung ( , biophys. j. : ) predicted an ic of . nm for piiia when the navab channel is occupied by sodium ions. even at very low [piiia] ( pm), the unblocked currents showed increasing rates of inactivation as the peptides were washed in, suggesting a gating mod- ulation, that was not tightly associated with pore block. for mctx piiia ( . nm), or kiiia ( nm), inactivation accelerated by ~ -fold. substitution of key basic residues (piiia-r a and kiiia-k a) reduced blocking potency and decreased the speeding of inactivation to less than -fold. given the remarkably high selectivity and affinity that mctxs show for certain eukaryotic nav channels with highly asymmetric pores, it may seem surprising that they bind to symmetric bacterial nav channels with such high affinity. https://core.ac.uk/display/ ?utm_source=pdf&utm_medium=banner&utm_campaign=pdf-decoration-v binding of isoflurane to a bacterial voltage-gated sodium channel: structure and accessibility of

an area of ongoing research. here we present a series of consecutive patients with locally advanced, recurrent, or metastatic cscc treated with pd- inhibitors and analyze tumor and blood genomics as well as pd-l expression with the aim of correlating with treatment response. methods we analyzed cases of cscc treated with single agent pd- inhibitors in the last years at wake forest. demo- graphic and outcome data were collected. tumor tissue, when- ever available, was tested for pd-l , tmb, msi, and genetic mutations. blood was tested for circulating tumor at the beginning of treatment and at the time of maximum response. results fourteen patients with cscc treated with pd- ici were included in this study. six had locally advanced disease, seven had recurrent locally advanced disease, and one had metastatic disease. four patients received treatment for > months and all had complete response (cr). five patients had – months of treatment and all had near cr (pending imaging studies and ctdna to confirm). three patients had < months of treatment and had partial response (pr). two of the patients had progressive disease, although one with pos- sible pseudoprogression based on review of post-treatment sur- gical pathology specimen. treatment was well tolerated with no immune related side-effects except one case of grade i hypothyroidism. eleven patients had sufficient tumor tissue for genomic and pd-l testing. initial blood genomic testing was performed in of patients and in follow up in patients who achieved maximum response. patients with cr had pd- l of at least %. the

studies in the humanities, university of edinburgh abstract this paper examines the background and content of thomas jefferson’s botanical garden plan for the university of virginia. when jefferson promoted the establishment of a botanical garden, european botanical gardens were evolving from physic gardens, and american botanical gardens were in their infancy. accordingly, this paper compares the botanical garden plan for the university of virginia with contemporary botanical gardens. this is examined by outlining the trends of botanical gardens in europe and the united states around the nineteenth century, analyzing their function and spatial structure. also, jefferson’s perspective on botany, his plan, and botanical gardens are reviewed. this study found that jefferson’s project had its background in the social recognition of the importance of botany as a practical science, advancing the national economy, which was a prominent goal in late eighteenth-century europe, and in developing networks of exchanging plants and information concerning botany and botanical gardens. based on the botanist correia’s opinion on the role of a public botanical garden, the botanical garden plan for the university of virginia was developed by jefferson as an action plan, including its site creation, space organization, and supplying of plants. compared to the other contemporary botanical gardens, the university of virginia’s botanical garden plan has the following characteristics. first, like european gardens in the late eighteenth century, it evolved from being a physic garden to a botanical one. as such, it emphasized botanical research and education over medicine, creating a tree garden and a plant garden. second, it differed from many european and american botanical gardens in that it rejected decorative elements, refused to install a greenhouse, and attempted to spread practical overseas plants suitable to the local climate. this study contributes to broadening the history of botanical gardens at the turn of the nineteenth century. key words: botany, harvard botanical garden, united states botanic garden, physic garden journal of the korean institute of

버지니아대학교 식물원 구상의 특징을 짚어내고자 하였다. 이를 위해 세기 전후 구미 주요 식물원의 역할과 공간 구조를 분석하여 경향을 파악하였다. 이와 함께 식물학과 식물원에 대한 제퍼슨의 관점과 식물원 구상안을 검토하며 버지니아대학교 식물원을 당대 사례와 비교 검토하였다. 연구 결과 그 배경은 세기 후반 유럽에서 두드러지게 나타난 국가 경제를 견인하는 실용 과학으로서 식물 교육과 연구의 중요성에 대한 사회 인식, 그리고 식물학과 식물원에 대한 정보와 식물을 교환하는 네트워크에서 찾을 수 있다. 버지니아대학교 식물원 구상은 공공 식물원의 역할에 대한 식물학자 코레아의 의견이 바탕이 되어 제퍼슨에 의해 부지 조성과 개략적인 공간 구성, 식물 수급 방안을 포함한 실행 전략으로 발전되었다. 동시대 식물원 사이에서 버지니아대학교 식물원 구상이 지니는 특징은 다음과 같다. 첫째, 초본 이외에 교목 정원을 별도로 구성하고 의학이 아닌 식물학 연구와 교육을 강조했던 측면에 서 세기 후반 유럽 식물원의 약용 식물원에서 식물원으로의 진화와 같은 경향을 보인다. 둘째, 장식적 요소를 배제하고 온실 설치를 거부하며 지역 기후에 적합한 해외 실용 식물을 확산시키려 했다는 점에서 유럽과 미국의 많은 식물원과 다르다. 본 연구는 버지니아대학교 식물원 구상을 사례로 세기 전후 식물원의 역사와 문화에 대한 이해의 폭을 넓히는 데 기여한다는 점에서 의의를 지닌다. 주제어: 식물학, 하버드대학교 식물원, 미국립식물원, 약용 식물원 figure . portrait of thomas jefferson by rembrandt peale, source: wikimedia commons Ⅰ. 서론 . 연구 배경과 목적 최근 몇 년 새 국내에서 식물원 조성 소식이 이어지고 있다. 국립백두대간수목원과 서울식물원이 문을 열었으며, 이 외에도 여러 식물원이 계획 혹은 조성 단계에 있다. 바야흐로 식물원 의 르네상스를 맞이하고 있다. 식물원의 존재 의의를 재고하고 미래 방향을 모색하기 위해 식물원의 역사를 되짚어보는 일이 더욱 필요한 시점이다. 본 연구는 미국의 제 대 대통령이었던 thomas jefferson ( ~ , figure 참조)이 년에 착수했던 버지니아대 학교 식물원 조성 계획을 살핀다. 비록 완성되지 못했으나, 다음 과 같은 사실을 고려할 때 이 식물원 계획은 주목을 요한다. 첫 째, 세기 후반부터 세기 초에 이르는 시기는 유럽의 식물 원들이 약용 식물원에서 식물원으로 진화한 때인데(o'malley, ; johnson, ; hickman, ), 당시 제퍼슨은 변화가 지속되고 있었던 파리 왕립식물원과 밀접한 관계를 맺고 있었 다(spary, ). 둘째, 세기 초는 미국에서 공공식물원 조성 이 본격화된 여명기였으며, 제퍼슨은 이러한 움직임을 이끈 주 요 인물이었다(o'malley, ). 미국립식물원(united states botanic garden) 설립을 추진한 사람 중 한 명이었고(o'malley, ), 뉴욕식물원의 전신인 엘긴식물원(elgin botanic garden) 과 하버드대학교 식물원 등에 씨앗과 식물을 제공하며 그 탄 생에 기여하였다(fox-bruguiere, ). 이러한 점을 고려할 때 제퍼슨의 버지니아대학교 식물원 계획은 세기 전후 미국 과 유럽 식물원의 동향에 대한 이해의 폭을 넓히는 적절한 사 례이다. 본 연구는 다음과 같은 질문에 대한 답을 구하고자 한다. 제 토머스� 제퍼슨의� 버지니아대학교� 식물원� 구상� 배경과� 내용 journal of the korean institute of landscape architecture 한국조경학회지� 제� 권� 호( 년� 월)� � 퍼슨이 버지니아대학교에 식물원을 조성하려 했던 배경은 무 엇인가? 제퍼슨이 구상했던 버지니아대학교 식물원의 모습은 어떠했나? 버지니아대학교 식물원 구상과 세기 전후 유럽과 미국의 식물원의 유사점과 차이점은 무엇인가? . 연구사 검토 토머스 제퍼슨이 버지니아대학교에 식물원을 설립하려 했다 는 사실은 그간 큰 조명을 받지 못했다. 단적인 예로 토머스 제 퍼슨의 조경가로서의 면모를 밝힌nichols and griswold( ) 의 thomas jefferson, landscape architect와 버지니아대학교 캠퍼스 계획을 소개한 thomas jefferson's academical village 은 식물원 계획을 다루지 않고 있다. 그러나 버지니아대학교의 식물원 계획이 전혀 언급되지 않 았던 것은 아니다. 세기 말에서 세기 초 유럽과 미국 내 식 물원을 과학 탐구와 픽처레스크 미학의 융합으로 논한 o'malley ( )의 연구에서 간략히 소개된 바 있다. o'malley( : - )는 제퍼슨의 식물원 계획을 과학과 자연식 정원에 대한 미 적 관점이 동시에 반영된 세기 초 미국의 여러 식물원과 같 은 경향을 지닌 사례로 규정했다 ). 그러나 제퍼슨의 글을 짧게 인용하는데 그치고 있어 동시대 식물원과 버지니아대학교 식 물원 계획의 유사성을 주장하기에 한계를 보였다. 버지니아대학교 식물원 계획은 fox-bruguiere( ; ) 의 연구를 통해 자세히 밝혀졌다. 그는 제퍼슨의 식물학과 식 물원에 대한 관심과 관련활동을 검토하며 식물원의 계획 배경 을 고찰하고, 년대에 작성된 버지니아대학교 식물원 구상 안 문서와 제퍼슨의 편지를 살펴 식물원 계획 내용을 드러냈다. 또한 년 제퍼슨의 서신을 조사하여 식물원 조성 과정을 정리하였다. 그는 식물원 설립 배경이 식물학 교육과 연구가 과학 수준을 앞당기고 국가의 진보를 견인하는 열쇠라는 제퍼 슨의 생각에 뿌리를 두고 있다고 주장했다. 이와 함께 제퍼슨이 저명한 식물학자 josé correia da serra( ~ )에게 요 청하여 식물원 구상안을 마련하였고, 박물학 교수 john patton emmet( ~ )를 통해 구상을 실현하려 했다는 등의 사 실을 밝히며 미완의 유산을 이해할 수 있는 토대를 구축했다. 그러나 그는 제퍼슨의 식물원 계획을 제퍼슨의 식물학에 대 한 관심과 활동 속에서 살폈을 뿐, 동시대 유럽과 미국의 식물 원의 경향과 비교하지 않았다. 또한 계획 수립 과정에서 조경 가로서 제퍼슨의 역할을 다루지 않았다. 버지니아대학교 식물원 계획을 “독창적이지도 특별하지도 않다(fox-bruguiere, : )”라고 평하며, 버지니아대학교 설립과 국가 진보에 대한 제퍼슨의 교육적․경제적․국가적 관점을 이해할 수 있는 수 단에 한정했다. 본 연구는 세기 전후 유럽과 미국의 식물원 동향을 고찰하 여 버지니아대학교 식물원이 동시대 식물원사에서 지니는 특 징을 드러내고, 코레아와 제퍼슨의 식물원 구상안을 비교하여 버지니아대학교 식물원 계획에 담긴 제퍼슨의 역할을 조명한 다는 점에서 앞선 연구와 차별성을 갖는다. . 연구 과정과 방법 연구 과정과 방법은 다음과 같다. 첫째, 제퍼슨의 버지니아 대학교 식물원이 동시대 식물원사에서 지니는 의미를 찾을 수 있는 토대를 마련하였다. 이를 위해 세기 후반에서 세기 초반 유럽과 미국의 식물원 동향을 개괄하였다. 특히 주요 식 물원을 중심으로 역할과 공간 구성 방식의 변화와 특징을 파악 하였다. 유럽 사례 중 제퍼슨이 크게 영향을 받았던 파리식물 원과 세기 후반 유럽 식물원의 진화를 잘 보여주는 사례인 에든버러식물원을 검토하였고, 미국 사례 중 초기 계획안과 식 물 목록이 전해지며 제퍼슨이 식물을 제공하기도 했던 하버드 대학교 식물원을 검토하였다. 둘째, 버지니아대학교 식물원의 특징을 이해하기 위하여 식물학 및 식물원에 대한 제퍼슨의 생 각과 입장을 파악하였다. 토머스 제퍼슨의 도서 목록(catalogue of the library of thomas jefferson) )에 기록된 식물학 관련 서적과 그의 버지니아 주에 대한 비망록(notes on the state of virginia) ) 중 식물에 대한 서술과 제퍼슨이 지인과 주고받 은 서신 중 식물원이 언급된 자료를 검토하였다. 이와 함께 본 연구는 fox-bruguiere( )가 다루지 않은 제퍼슨과 임용 담 당자 francis walker gilmer( ~ ) )가 주고받은 서신을 분석하며 차후 식물원 조성책임을 맡는 박물학 교수 임용 과정 을 조사하였다. 셋째, 버지니아대학교 식물원 구상 내용에서 공 간적 특징을 파악하였다. 이를 위해 버지니아대학교 도서관에 소장된 코레아의 식물원 구상안 )과 미국회도서관에 소장된 년 월 일 제퍼슨이 작성한 식물원 설립 제안 서신 )을 살펴, 같은 시기 유럽과 미국의 식물원과 유사점 및 차이점을 찾고자 하였다. Ⅱ. ~ 세기 식물원의 동향 . 유럽의 식물원 년에 설립된 피사대학교의 식물원을 시작으로 ~ 세 기 유럽의 여러 의과대학은 약물학(materia medica) 연구와 교육을 위해 약용 식물원을 조성하였다(johnson, ; hunt, ). 그러나 세기에 이르러 다음과 같이 식물원에 변화를 일으킬저변이 형성되었다. 사탕수수, 담배, 커피등 실용 식물 의 발견과 유입으로 식물 수집 대상이 약용 식물에서 실용 작 물로 확장되었으며, 년 린네의 식물철학(philosophia bo- tanica) 발표 이후 식물 탐구는 의약학에서 박물학 혹은 식물 journal of the korean institute of landscape architecture 김정화 한국조경학회지� 제� 권� 호( 년� 월) a: plan of jardin du roi, b: plan of jardin du roi, c: plan of jardin du roi by gabriel thouin, figure . changes in plans of the botanic garden edinburgh source: a, b: http://www.ctgpublishing.com, c: wikimedia commons 학으로 분리 발전되었다(findlen, ). 이러한 변화는 영국의 여러 식물원에서도 발견된다. 예컨대 에든버러 식물원은 년 에든버러대학교의 의학교수이자 왕 의 식물학자로 부임한 john hope( ~ )의 주도 아래 새 식물원을 계획하고 조성했다. 의과대학 옆 기하학적 구조로 이 루어진 개의 직사각형 토지에 종과 속 그리고 알파벳 순서에 따라 식물을 배열했던 이전의 약용 식물원(doyle, )과 달 리, 호프는 약용 식물 교육 공간(schola botanica)은 작게 구성 함과 동시에 교목 연구와 교육 공간(sylva botanica)을 크게 마 련하고 온실을 건축했다. 특히 당대 픽처레스크 미학에 영향을 받은 그는 교목 정원을 곡선형길과 비정형적인 소정원들로 이 루어진 공간으로 계획하였다(lausen-higgins, ). 케임브리 지대학교 식물원도 년에 부임한 john stevens henslow ( ~ ) 교수를 중심으로 약용 식물원에서 식물원으로 거듭나기 위한 계획을 수립했다. 교목을 적극적으로 도입했던 헨슬로우 역시 정원을 곡선형의 유기적 형태로 계획하며 당대 정원 미학을 반영했다(parker, ). 파리의 약용 식물원(jardin du roi) 역시 세기를 지나는 동안 변화를 도모했다. 먼저 년 박물학자 georges louis leclerc de buffon( ~ )이 원장으로 임명되면서 식물원 의 주 관심사가 약용 식물에서 교목, 특히 프랑스 기후에 적용 할 수 있는 북미 교목으로 이동하였다. 그 결과, 년에 이르 러 식물원에서 가장 큰 부분을 차지하는 공간은 교목 재배지가 되었다(spary, : - ; figure -a, -b 참조). 이러한 변화는 프랑스 혁명 후에도 지속되어 andré thouin( ~ ) 이 원장으로 임명된 시기에는 투인과 그의 형제이자 조경가였 던 gabriel thouin( ~ )에 의해 확장 계획이 수립되었 고(figure -c 참조), 식물학, 광물학, 동물학을 아우르는 대표 적인 자연과학 기관으로 거듭났다(petersen, ). . 미국의 식물원 세기 초 미국의 식물학 연구는 시작 단계에 있었다. 년 미국에 첫 발을 들인 코레아는 미국의 식물학 연구 수준을 다음과 같이 묘사했다. 미국의 식물학은 아직까지 초기 단계로, 일부 아마추어들이 대륙 전체에 흩어져 있고 일부 유럽인들은 식물학자라기보다 여행하는 정원가로서 돈 많은 유럽 사람의 정원이나 식물 재배지를 위해 식 물, 관목, 나무를 수집하고 있다 ). 년 이전까지 미국의 식물 수집과 탐구를 주도한 집단은 학자가 아닌 식물 애호가들이었다(hedrick, ). 식물원을 조 성한 사람들 역시 개인적인 관심 혹은 원예 사업차‘신세계’ 미 국을 탐험하며 식물을 채집하던 이들이었다. 예를 들어 년 필라델피아에 조성된 미국의 첫 식물원은 평생 미국을 여 행하며 식물을 수집하고 여 년간 첼시 약용 식물원의 peter collinson( ~ )과 서신과 씨앗을 주고받았던 식물 애호가 john bartram( ~ )의 정원이었다(hill, ; bailey, ). 미국의 식물 수집과 탐구는 년대에 이르러 활발해지기 토머스� 제퍼슨의� 버지니아대학교� 식물원� 구상� 배경과� 내용 journal of the korean institute of landscape architecture 한국조경학회지� 제� 권� 호( 년� 월)� � figure . undated plan of the botanic garden at cambridge, harvard college source: courtesy of the botany libraries, harvard university 시작했다. 이때부터 년대까지 상당량의 이국 식물이 미국 으로 유입되면서 많은 식물원이 설립되었다(hedrick, ). 특 히 식물학이 미 대륙 내 실용 작물을 발견하여 국가 경제와 과 학 발전에 이바지하고 동시에 유럽에 대한 미 대륙 자연의 풍 부함을 드러낼 수 있다는 미 건국기 사회 리더들의 생각은 공 립 식물원 탄생의 원동력이 되었다(o'malley, ). 신호탄은 미국의 초대 대통령 george washington( ~ )이 년 에 작성한 청원서로, 그는 워싱턴dc 도시계획에 식물원을 포함 할 것을 요청하며 미국립식물원 설립의 기초를 닦았다(solit, ; fallen, ). 세기 초에는 여러 대학기관도 식물원 설립에 관심을 두기 시작해 첫 여 년 동안 하버드, 예일, 프린스턴, 사우스 캐롤리 나, 펜실베이니아대학교 등이 부설 식물원을 설치했다(o'malley, ). 이 중 년에 식물원을 조성한 하버드대학교의 사례 를 살펴보면 식물원 둘레로 곡선형의 동선을 따라 교목과 관목 전시 공간이 배치되었고, 중심에 온실과 교육 공간(garden of arrangement on botanic school)이 기하학적 구조로 배치되었 다(figure 참조). 년에 발간된 식물목록에 따르면 하버 드대학교 식물원은 국내외에서 수집한 실용 식물과 약용 식물 을 비롯해 장식용 식물까지 수집하여 총 , 종에 이르는 식 물을 보유하고 있었다 ). 정리하면, 제퍼슨이 버지니아대학교 식물원 설립에 착수하던 시기 전후로 유럽과 미국의 식물원들은 각각 전환기와 여명기 에 놓여 있었다. 세기 말 유럽의 식물원들은 의학 탐구 정원 에서 식물학 연구 기관으로 진화하면서 실용 식물, 특히 교목 을 적극 수집하고 배열하였고, 세기 초 미국의 식물원들은 의 학과 박물학의 경계에서 식물학 연구와 교육을 시작하며 대학 의 부설 기관으로 출발했다. Ⅲ. 제퍼슨의 식물학과 식물원에 대한 관점 . 식물학에 대한 관심 제퍼슨은 식물학에 깊은 관심을 두었다. 그의 정원과 philip miller( ~ )의 정원사의 사전(gardener's dictionary), 그리고린네의책등은 그의 식물학 지식의 원천이 되었다(ewan, ). 토머스 제퍼슨의 도서 목록 중 식물학 관련 서적은 pedanius dioskorides, jean jacques rousseau, erasmus darwin, mark catesby, carl von linnaeus 등이 저술한 총 권으로, 제퍼슨은 고대 그리스의 약학서부터 동시대 저명한 학자의 박 물학서까지 소장하고 있었다 ). 그의 식물학 지식은 호기심을 넘어 상당한 수준에 이르렀던 것으로 알려져 있다. 버지니아 주에 대한 비망록에서 학명을 사용해 버지니아의 식물을 나열하는 것에서 그의 박물학, 식물 학 지식수준을엿볼수 있다 ). 이외에도bernard jussieu( ~ )의 분류 체계보다 린네의 식물 분류법이 보다 합리적인 이유를 설명한 그의 편지(ewan, ), 미국의 첫 식물학 교과 서 저자 benjamin smith barton( ~ )이 제퍼슨의 박물 학 지식을 높이 평가하며, 새로 발견한 식물에 그의 이름을 붙 인 이야기(betts, : - ) 등 제퍼슨의 식물학 수준의 깊 이를 보여주는 여러 가지 일화가 전해진다. 년부터 년까지 외교관으로서 프랑스에 거주하며 쌓 은 유럽 식물학자들과의 친교 관계는 제퍼슨이 세기 전후 세 계 식물 네트워크의 주요 인물로 자리매김하는 토대가 되었다 (rice, ). 년 저명한 과학자 alexander von humboldt ( ~ )는 버지니아 산 담배 씨앗과 메릴랜드 산 담배를 요청하기 위해 제퍼슨에게 서신을 보냈으며(andress, ), 파리 왕립식물원 원장 투인과 제퍼슨의 관계는 곧 미국과 프랑 스 간 식물 교환 통로로 작용했다(spary, ). 제퍼슨에게 식물학은 개인의 지적 호기심이나 취미 활동 이 상의 의미를 지녔다. 미 건국기의 사회 리더로서 그는 식물학 을 “가장 귀중한 과학” ) 혹은 국가에 대한 “가장 위대한 일” ) 로 규정했다. 이러한 태도는 제퍼슨이 조지 워싱턴과 같이 실 용성에 주목하여 식물학이 국가 발전을 견인할 수 있는 중요한 과학 분야라고 생각하고 있었음을 보여주는 것이자 공공의 자 원으로서 식물원 설립의 필요성을 인식하고 있었음을 내포하 는 것이다. . 식물원에 대한 관점 식물학 네트워크의 주요 인물 중 한 사람이었던 만큼 제퍼슨 은 국외 주요 식물원을 방문하거나 소식을 접했다. 특히 년부터 년까지 프랑스 공사로서 파리에 거주하던 때에는 뷔퐁의 감독 아래 교목 수집과 공간 확장 등의 변화를 추구하 journal of the korean institute of landscape architecture 김정화 한국조경학회지� 제� 권� 호( 년� 월) 고 있던 파리식물원과 긴밀한 네트워크를 쌓았으며, 미국으로 돌아간 후에도 꾸준히 파리식물원으로부터 씨앗을 전해 받았 다(spary, ). 년에는 당시 갓 개원한 리버풀식물원의 연설문(address at the opening of the botanic garden of liverpool)과 식물 목록(a catalogue of plants in the botanic garden, at liverpool)을 전해 받기도 했다(ewan, ). 이외 에도 제퍼슨은 파리에 거주하던 시기 옥스퍼드와 큐를 비롯한 영국의 여러 도시와 정원을 여행했는데, 그가 남긴 글에서 식 물원에 대한 의견은 보이지 않는다. 큐 정원을 방문하기는 했 으나 그는 식물원이 아닌 물을 적극활용한 정원으로 인식했다 (wilson and stanton, : - ). 이러한 일련의 예들은 그 가 식물원을 해외 식물을 확보할 수 있는 장소로 여기고 있었 으며, 여러 식물원들 중에서도 영국의 식물원들보다 파리식물 원으로부터 강한 영향을 받았음을 가리킨다. 식물원의 방향성에 대한 제퍼슨의 생각은 앞서 살핀 세 기 말영국과 프랑스 등지에서 일어난 식물원의 변신, 약용 식 물원에서 자연과학 기관으로의 발전과 접점을 이루고 있었다. 버지니아 주에 대한 비망록에서 나타난 식물 구분법을 보아 도 기본적으로 그는 식물을 약용에 한정하지 않고, 약용, 식용, 장식용, 실용 식물로 구분했다 ). 차후 식물원 조성책임을 맡는 박물학 교수를 임용하는 과정에서도 이러한 태도가 엿보인다. 제퍼슨이 자신을 대신하여 버지니아대학교 교수 채용을 담당 했던 길머와 주고받은 서신에서 의학과 박물학(natural history) 각각 교수를 채용하려 했던 사실은 그가 이 둘을 별개의 학문 으로 규정하고 있었고 ), 박물학을 화학을 비롯해 지질학, 동물 학, 식물학을 아우르는 자연과학으로 인식하고 있었음을 알려 준다 ). Ⅳ. 버지니아대학교 식물원의 계획과 추진 과정 . 식물원 조성 계획 제퍼슨은 년 박물학자 john bradbury( ~ )의 워싱턴시 식물원 설립 소식에 대한 편지에 “과학에 흥미를 지 닌 자라면 누구나 바라는 일” )이라고 답하며, 식물원 설립에 뜻이 있음을 간접적으로 내비쳤다. 그러나 그가 버지니아대학 교 식물원 설립에 착수한 때는 년대에 들어서였다. ) 년 손턴의 식물원 설립 제안 년 제퍼슨의 버지니아대학교 식물원 구상을 논하기에 앞서 세 건의 문서를 살펴볼 필요가 있다. 이미 년과 년 그리고 년경, 각자 다른 세 사람이 제퍼슨에게 버지니 아대학교 내에 식물원을 조성할 것을 권했기 때문이다. 모두 계획도면이 없는 서신에 불과하지만, 그들의 제안은 시기적으 로 제퍼슨의 식물원 계획에 앞서기에 차후 그의 계획안에 일정 한 영향을 미쳤을 가능성을 배제할 수 없다. 년 제퍼슨의벗이자 미국회의사당건축가로알려진 william thornton( ~ )이 대학교 내 식물원 조성을 제안하였다. 손턴은 그 이전에도 제퍼슨과 워싱턴의 국립식물원 설립에 관 해 몇 차례 서신을 주고받으며 공공 식물원에 대한 남다른 관 심을 표했던 인물이다(fox-bruguiere, ). 년 당시 손 턴은 제퍼슨과 아카데미컬 빌리지와 파빌리온 구상에 대한 의 견을 주고받고 있었는데, 당해 월 일의 편지에서 파빌리온 설계에 대한 의견을 서술한 뒤, 분수, 숲, 운동 공간 등 학교에 필요한 몇 가지 시설을 추가로 제시하며, “식물원이 있어야 한 다” )고 말했다. 그러나 손턴의 식물원 조성 제안에 대한 제퍼 슨의 답장은 확인되지 않는다. ) 년 쿠퍼의 식물원 설립 제안 년 월, 버지니아대학교의 아카데미컬빌리지 건설이 착 수되고 마당(lawn)과 정원 계획이 본격화되던 때(wilson et al., ), 제퍼슨은 또 다른 이로부터 식물원 조성 제안을 받 았다. 버지니아대학교의 화학 및광물학 담당 교수로 예정되었 던 thomas cooper( ~ )였다. 월 일 쿠퍼는 제퍼슨 에게 보낸 편지에서 학과 운영에 대한 몇 가지 생각을 밝히며, 파리식물원에서 매년 보내는 씨앗을 직접 탐구할 수 있도록 식 물원을 설립하자고 제안하고 식물학자를 추천하기까지 했다 ). 이에 대한 제퍼슨의 답장에서 쿠퍼가 추천한 식물학자에 대한 관심은 보이나, 식물원에 대한 의견은 보이지 않는다 ). 이후 쿠퍼가 버지니아대학교에 임용되지 못하였고, 이와 함께 그의 제안도 구체화되지 못했다. ) 년경 코레아의 식물원 구상안 버지니아대학교 도서관에 소장된 문서 가장 실용적이며 저 렴한, 공립학교를 위한 식물원 계획(plan for a botanic garden for a public school, on the most useful, and least expensive plan) 은 작성일 미상이다. 그러나 fox-bruguiere( )는 년 코레아가 미국을 떠나기 전 제퍼슨의 몬티첼로를 방문했을 때 제퍼슨의 요청으로 이 문서를 작성한 것으로 추정한다. 이러한 경위로 미루어 보아 제퍼슨은 쿠퍼가 식물원 설립을 제안한 때 부터 코레아가 몬티첼로에 방문했던 시기 사이에 버지니아대 학교 내 식물원 설립을 고려하기 시작한 것으로 판단된다. 내용은 다음과 같은 세 가지로 구성되어 있다. 첫째, 식물원 의 역할이다. 식물 목록 증대와 수집 자체에 혈안이 된 동시대 식물원을 비판하며, 코레아는 식물원의 초점은 식물 교육이어 야 한다고 강조하였다. 둘째, 이어서 그는 식물원의 교육과 연구 방향을 제시하였다. 구체적으로는 과학으로서 식물 해부학 및 생리학, 린네의 분류 체계를 따른 식물 분류학(distinguishing 토머스� 제퍼슨의� 버지니아대학교� 식물원� 구상� 배경과� 내용 journal of the korean institute of landscape architecture 한국조경학회지� 제� 권� 호( 년� 월)� � a: serpentine wall at the campus b: jefferson's sketch of serpentine walls for the academical village, about - figure . serpentine wall source: a: photo by author in march , b: nichols, , p. plants), 프랑스 혁명 정신과 상통하는 진정한 과학으로서 식물 체계화(grouping), 가장 유용한 학문으로서 식물 활용 연구 그 리고 식물 문헌학 등 다섯 가지였다. 셋째, 식물 유형으로 그는 교육과 연구 취지에 적합한 식물을 도입할 것을 권하였다. , 종의 식물로 이루어진 에이커 규모의 정원과 교목으로 이루어진 에이커규모의 부지를 설정하고, 미국 내 식물 확산 을 위해 식물원의 식물과 교목은 모두 버지니아 비자생종이어 야 한다고 주장하였다 ). 정리하면, 식물원의 부지 규모를 언급한 것 이외 공간 계획 에 관한 생각이 엿보이지 않기에 그의 구상안은 식물원의 비전 과 미션 제시에 초점을 둔 제안서라 할 수 있다. 제안 방향은 자연과학 교육에 충실한 식물학 수업의 실습장이자 미국에 유 용한 식물을 확산시키기 위한 일종의 시험장을 설립하는 것이 었다. ) 년 제퍼슨의 식물원 구상안 제퍼슨이 버지니아대학교 식물원 설립에 본격적으로 착수한 때는 년이다. 제퍼슨은 사망하기 몇 달 전인 월 일 버지 니아대학교의 박물학장 에머트에게 식물원 설립 계획을 전하 는 편지를 보냈다. 버지니아대학교가 개원한 지 년이 되어 가 는 때이자, 에머트가 교수로 부임한 지 년이 되는 때였다 ). 편지는 크게 네 가지 내용으로 이루어져 있다. 첫 번째는 식 물원 설립에 착수하길 요청하는 내용으로, 바로 “이제 우리 대 학에 식물학과의 도입을 생각할 때” )라는 문장으로 시작한다. 두 번째는 코레아의 식물원 구상안 소개로, 구상안 요청 배경 과 요청 내용도 함께 설명하였다. 세 번째는 식물원 설립을 위 한 네 가지 과제로, 그는 번호를 붙여가며 부지 선정, 담장 조 성, 지형 그리고 식물 목록에 대한 의견을 제시하였다. 네 번째 로 식물 종류와 수급 방안을 서술하였다. 제퍼슨은 코레아의 교육과 연구 기능에 충실한 온실 도입을 배제하고, 탐닉적이지 않은 ‘절제적인 관점'에 만족감을 표하며 ), 코레아의 제안 대부분을 수용했다. 코레아의 제안대로 식물 로 이루어진 에이커의 정원과 교목으로 구성된 에이커 규모 의 식물원을 구상했고, 식물 종류에 있어서도 코레아의 의견대 로 식물학 탐구에 충실한 식물을 수급하고, 국가에 이익이 되 는 비자생 교목을 도입할 것을 강조하였다 ). 물론 제퍼슨이 코레아의 제안을 절대적으로 따르기는 했으 나, 에머트에게 제시한 네 가지 과제를 살펴보면 건축과 조경 에 대한 자신의 지식과 경험을 바탕으로 코레아의 제안을 실행 하기 위한 보다 구체적인 구상안을 마련하였음을 알 수 있다. 코레아가 제시한 규모 이외에 토양, 급수, 거리 등을 종합적으 로 고려하여 캠퍼스 상단 도로변 토지를 식물원 부지로 선정하 였다. 아카데미컬빌리지에 구현한 바 있는 구불구불한 벽돌담 (serpentine wall;

Ⅴ. 결론 제퍼슨의 버지니아대학교를 위한 식물원 계획 배경은 연구 결과 다음과 같은 두 가지로 요약된다. 첫째, 세기 후반부터 유럽에서 대두된 자연과학으로서 식물학의 중요성에 대한 인 식과 국가에 경제적 이익을 가져오는 식물학의 효용성에 대한 동시대 미국에서의 믿음이다. 둘째, 제퍼슨의 식물학 및 식물 네트워크이다. 여러 식물학자와 탐험대로부터 수집한 식물과 씨앗은 버지니아대학교 식물원 설립의 당위성과 실현 가능성 으로 작용하였다. 특히 제퍼슨이 주변 인물들의 제안 후에 학 교 내 식물원 설립을 구상하기 시작한 사실과 식물원의 방향에 대한 코레아의 생각을 수용한 것으로 보아, 그의 식물학 네트 워크가 버지니아대학교 식물원 조성 착수에 결정적인 역할을 한 것으로 판단된다. 동시대 구미에서 식물학의 사회적 위상과 제퍼슨의 네트워 크와 같은 조건이 버지니아대학교 식물원 설립의 배경이었다 하더라도, 계획 실행은 제퍼슨이 있었기에 가능했다. 에머트에 게 보낸 서신에서 드러나듯, 현장답사와 측량, 재료 계산, 공간 구상, 식물 수급 계획 등을 수립하고 실시한 자는 제퍼슨이었 다. 제퍼슨이 년 월 한 달 동안 추진력을 보일 수 있었던 이유는 세기 초 유럽과 미국 사회에서 식물학의 가치를 읽어 내는 통찰력, 식물학에 대한 개인적인 관심과 열정, 네트워크 그리고 정원에 대한 그의 경험과 지식이 밑바탕에 있었기 때문 이다. 담장으로 식물원을 위요한다거나, 비탈진 언덕을 계단형 으로 조성하려는 생각, 부지 선정 시 거리와 물 공급을 고려하 는 부분이 이를 뒷받침한다. 세기 전후 유럽과 미국의 주요 식물원들과 비교해볼 때 버 지니아대학교 식물원 구상이 보이는 특징은 다음과 같다. 첫째, 초본 이외에 교목 정원을 별도로 구성하고 의학이 아닌 박물학 토머스� 제퍼슨의� 버지니아대학교� 식물원� 구상� 배경과� 내용 journal of the korean institute of landscape architecture 한국조경학회지� 제� 권� 호( 년� 월)� � 의 일부분으로서 식물학 연구와 교육을 강조했던 측면에서 세기 후반 유럽 식물원들이 약용 식물원에서 식물원으로 발전 한 흐름과 같은 경향을 보인다. 둘째, 코레아와 제퍼슨은 호기 심이나 장식적 요소를 배제하며 온실 설치를 거부하였고, 버지 니아대학교 식물원을 지역 기후에 적합한 해외 수종을 도입하 고 확산시키기 위한 실용 식물 연구 장소로 계획했다. 이러한 방향성은 온실을 설치했던 유럽과 미국의 많은 식물원과 다른 부분으로, 특히 온실을 건축하고 실용 식물 이외에 약용 식물 과 장식용 식물까지 두루 수집했으며 국내외 수종을 가리지 않 았던 하버드대학교 식물원과 대조를 이룬다. 본 연구는 코레아와 제퍼슨의 버지니아대학교 식물원 조성 배경과 구상 내용을 당시 유럽과 미국의 식물원과 비교함으로 써 그 특징을 드러냈다는 데 의의를 지닌다. 버지니아대학교 식 물원 구상은 세기 전후 유럽 식물원의 진화 방향을 반영하면 서도, 동시에 다른 식물원과 달리 장식적 요소를 배제하고 실 용 식물 연구와 확산을 추구한, 공공성을 강력하게 띄었던 사 례이다. 따라서 제퍼슨의 버지니아대학교 식물원 조성 계획은 미국 초창기 식물원의 파리를 중심으로 한 유럽 식물학계 및 식물원과의 관계, 그리고 식물원의 사회적 역할과 공공성에 대 한 국가 리더의 생각이 반영된 독특한 사례이다. 현재까지 드러난 자료만으로는 미완에 그친 버지니아대학교 식물원의 공간 구조와 식물 전시 방식을 구체적으로 파악하기 어렵다. 이에 따라 본 연구는 버지니아대학교 식물원 구상에서 세기 전후 구미의 식물원에서 나타나는 비정형적인 공간 구 조와 같은 정원 양식의 변화를 논하지 못한 한계를 지닌다. ------------------------------------- 주 . o'malley( : - )는 제퍼슨과 그의 동료들이 원 서식지를 모사한 자연 풍경 속에서 식물을 관찰하는 것이 식물 과학과 교육 기능에 적합하다고 생각했다고 주장하였으나, 이를 뒷받침하는 인 용 부분은 식물 생리학 교육과 연구 장소로서 식물원의 기능을 강 조하는 글로, 자연식 풍경이나 미적 측면에 대한 생각이 보이지 않 는다. o'malley의 버지니아대학교 식물원에 대한 해석은 재고될 필 요가 있다. 주 . 미국의회도서관의 서지학자 emily millicent sowerby( ~ ) 가 년에 시작해 년에 완성한 토머스 제퍼슨의 도서 목록이 다. 토머스 제퍼슨의 년 도서 목록과 년 미국의회도서관에 판매된 도서 목록을 바탕으로 작성되었는데, 총 권 중 권의 쪽 부터 쪽에서 식물학 관련 도서 목록을 확인할 수 있다(http:// hdl.loc.gov/loc.rbc/jeffcat. ). 주 . 프랑스 외교관의 미국에 대한 질문에 대한 제퍼슨의 답으로 구성된 책으로, 버지니아 주의 지형, 자원, 동물과 식물, 역사 등이 기술되 어 있다. 주 . 길머는 버지니아 출신의 법률가로, 버지니아대학교 초대 법학 교수 로 임용될 예정이었으나 사망으로 인해 자리에 오르지 못했다. 어 린 시절 제퍼슨을 통해 소개 받은 코레아와 식물 조사 여행을 다녔 고, 장 자크 루소의 글 중 식물학의 즐거움에 관한 부분을 영문으로 번역할 만큼 식물학에 깊은 관심과 지식을 보였다(davis, ). 주 . 가장 실용적이며 저렴한, 공립학교를 위한 식물원 계획(plan for a botanic garden for a public school, on the most useful, and least expensive plan) . papers concerning the establishment and construction of the university of virginia, - . accession # -b, at the special collections, university of virginia library. 주 . letter form thomas jefferson to john patton emmet, april , , in the thomas jefferson papers, - at the library of congress. 주 . “botany is still in her infancy in america; some amateurs are scattered throughout this continent, and some european rather traveling gardeners than real botanist, are collecting plants and shrubs and trees for the gardens of european rich men, or for the nurseries.

shirihai , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, boston university, boston, ma, usa. emerging evidence shows the importance of genes controlling mitochondrial fusion in physiology and their deregulation in neurodegenerative and metabolic disorders. however, apart from djm, the biophysical properties of the fusion- competent mitochondria remain elusive. to evaluate the conditions of contact formation and fusion, we used organelle-targeted fluorescent proteins, includ- ing photoactivatable gfp, which allow tracking of individual mitochondria. in h c cells, almost every mitochondrion is aligned with microtubules that pro- vide the primary tracks for mitochondrial movement. our results show that ~ % of fusion events involve moving mitochondria. however, fusion occurs irrespective of mitochondrial speed. furthermore, ~ % of fusion events in- volve the tip portion of the mitochondrion, whereas only ~ % of these events involve organelle side. nocodazol, a microtubule disrupting agent that inhibits mitochondrial movements decreases the fusion frequency and changes mito- chondrial fusion sites. strikingly, - % of the physical contacts between ad- jacent mitochondria did not result in fusion events. to evaluate whether the fu- sion efficacy depends on the spacing between the outer and inner mitochondrial membranes we used drugs that alter the matrix volume. valinomycin, a k þ ion- ophore that induces matrix swelling evoked a decrease in mitochondrial motil- ity leading to fewer contacts among mitochondria but the number of fusion events was maintained, indicating an increase in fusion efficacy. this change occurred at a low valinomycin concentration ( . nm) that did not affect djm or opa cleavage. nigericin ( . mm), a k þ /h þ ionophore that induces shrinkage of the matrix elicited fusion inhibition and mitochondrial aggrega- tion. importantly, no motility inhibition or opa cleavage occurred at the same time and the djm was increased. these results suggest that mitochon- drial fusion is facilitated by mitochondrial motility, the key determinant of the inter-mitochondrial encounter numbers and preferentially involves the front-tip of the moving organelle. in addition, fusion efficacy depends on the mitochondrial matrix volume. -pos mitochondrial fusion dynamics in human skeletal muscle-derived cells veronica eisner, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. mitochondria have a fundamental role in both muscle physiology and pathol- ogy. mitochondrial fusion and fission are important for energy metabolism, calcium homeostasis and cell death. however, the mechanisms underlying mitochondrial dynamics are poorly understood, especially in physiological models such as skeletal muscle. here we evaluated mitochondrial fusion dy- namics in human skeletal muscle cells (husmc). skeletal muscle satellite cells were isolated from human muscle biopsies and were maintained and dif- ferentiated in cell culture. mitochondrial fusion events were evaluated by con- focal imaging of cells expressing mitochondria matrix targeted dsred and matrix targeted or outer mitochondrial membrane (omm) targeted photoacti- vatable-gfp. when we tagged the mitochondria in ~ % of total cellular area with photoactivated-gfp, we found those mitochondria undergoing matrix fusion with a frequency of . . events/min/cell (n= ). among the fusion events, % led to complete fusion and only % was followed by separation at the apparent fusion site within to seconds. both complete and transient fusion events resulted mostly from longitudinal mergers, involving end to end interaction or from mergers of adjacent mitochondria in side to side orien- tation. furthermore, we found that omm and matrix fusion are sequential and separable steps, displaying . seconds gap (n= ). finally, we evaluated the mitochondrial fusion dynamics in husmc derived from both normal and malignant hyperthermia susceptible individuals. at resting state, no significant differences were found in the number of events or in their characteristics. thus, mitochondrial fusion commonly occurs in husmc, and enables mixing of both soluble and integral membrane factors. this process would help to maintain the stability of mitochondrial metabolism. the relatively low frequency of the tran- sient fusion is probably due to the parallel organization of the cytoskeletal tracks for mitochondria and to the limited mitochondrial motility. -pos imaging interorganelle contacts and local calcium dynamics at the er-mitochondrial interface györgy csordás , péter várnai , tünde golenár , swati roy , george purkins , tamás balla , györgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary, national institutes of child health and human development, bethesda, md, usa. the local coupling between er and mitochondria is essential for proper cell function. a main role of the er-mitochondrial junctions is to provide a local calcium signaling domain that is important both for keeping energy production in line with demand and for the control of apoptotic mechanisms. so far it has not been possible to visualize the tiny er-mitochondrial contact points in living cells or to monitor the localized [ca þ] changes in the narrow space between er and mitochondria ([ca þ]er-mt). here, we exploited rapamycin-mediated heterodimerization of fkbp and frb domains of fluorescent protein constructs respectively targeted to the outer mitochondrial membrane and the er as drug-inducible inter-organelle linkers to identify er-mitochondrial contacts and to measure the [ca þ ]er-mt. high- resolution fluorescence imaging and d reconstruction revealed rapamycin-in- duced clustering of the er-targeted fluorescent linker-half to the contact areas with the mitochondria without major changes in the spatial arrangement of the er. essentially all mitochondria displayed contacts with the er in both rbl- h and h c cells. plasma membrane-mitochondrial contacts were less frequent with er stacks being inserted between the two organelles. single mitochondria display discrete patches of er contacts as well as continuous as- sociations. cytoplasmic and mitochondrial matrix [ca þ] showed robust er-mitochondrial ca þ transfer with considerable heterogeneity even among adjacent mitochondria. pericam-containing linkers revealed ip -induced [ca þ ]er-mt signals that were resistant to buffering bulk cytosolic [ca þ ]c in- creases and exceeded um. the largest [ca þ ]er-mt signals did not occur at the tightest associations, indicating space requirements for the ca þ transfer machinery and functional diversity among er-mitochondrial junctions. these studies provide direct evidence for the existence of high ca þ microdo- mains between the er and mitochondria in living cells, and open new possibil- ities to probe the functional importance of this specialized compartment. -pos dependence of er-mitochondria calcium transfer on different ip receptor isoforms tunde golenar , szava bansaghi , gyorgy csordas , david i. yule , suresh k. joseph , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, university of rochester medical center, rochester, ny, usa. ip receptors (ip rs) release ca þ from the er, which is locally relayed to the mitochondria to control several aspects of mitochondrial function. recent stud- ies have suggested that type ip rs (ip r ) are particularly important for me- diating the ca þ transfer at the er-mitochondrial interface. we set out to sys- tematically evaluate the respective role of each ip r isoform in chicken dt cell lines that express only one ip r isoform (double-knockout, dko , dko and dko ) or provide a null-background (triple-knockout, tko) for analysis of mammalian ip rs and their mutants. simultaneous imaging of cytoplasmic and mitochondrial matrix [ca þ] ([ca þ]c and [ca þ]m) was performed in either permeabilized cells chal- lenged with ip or in muscarinic receptor overexpressing intact cells stimulated with carbachol (cch), an ip -linked agonist. saturating ip evoked complete discharge of er calcium and resulted in comparable [ca þ]m increases in each dko. furthermore, the cch-induced [ca þ]c spike was closely followed by a [ca þ]m rise in each dko. when tko cells were rescued with rat ip r or ip r , the latter mediated a larger [ca þ]c transient but the [ca þ]m increases were very similar for both isoforms. the relationship between the [ca þ]c peak and the corresponding [ca þ]m response was also very similar for ip r and ip r . to assess the impact of the release kinetic through ip r in the mitochondrial ca þ transfer we used two point mutants of the ip r , which display either enhanced inhibition by ca þ (d n) or are relatively insensitive to ca þ inhibition (d n). d n showed dampened [ca þ]m signal and [ca þ]m vs. [ca þ]c relationship, whereas d n displayed a steeper [ca þ]m vs. [ca þ]c relationship than the wild type ip r . thus, each ip r isoform can support local er-mitochondrial ca þ transfer and their competence to activate mitochondrial ca þ uptake depends on their deactiva- tion kinetic. biophysical properties of mitochondria undergoing fusion mitochondrial fusion dynamics in human skeletal muscle-derived cells imaging

nantes hospital, nantes, france; hopital st louis, paris, france treatment options for adults with primary refractory aml (pref aml) are extremely limited. whilst sibling allogeneic stem cell transplantation can result in long term survival most pa- tients lack a matched family donor and are destined to die of refrac- tory disease. greater availability of unrelated donors and improvements in supportive care have increased the proportion of patients with pref aml in whom allografting is technically fea- sible but the outcome of unrelated donor transplantation in this population has not been extensively studied. we therefore analysed overall survival in patients with pref aml who underwent unrelated donor transplantation between and with a me- dian follow-up of months ( - ). patients received three or more courses of induction chemotherapy. the median percentage of bone marrow (bm) blasts at transplant was %. the -year overall survival for the whole group was %. in multivariate anal- ysis, fewer than three courses of induction chemotherapy, a lower percentage of bm blasts at transplant and patient cmv seropositiv- ity were associated with improved survival. we used the prognostic factors identified in multivariate analysis to develop a scoring sys- tem. this allowed the delineation of four prognostic groups with survival rates ranging between % and %. this study dem- onstrates an important role for unrelated donor transplantation in the management of selected patients with pref aml and confirms the importance of initiating an urgent unrelated donor search in pa- tients with no matched sibling donor who fail to respond to induc- tion chemotherapy. pre-transplant factors allow the identification of patients with pref aml who are likely to benefit from unre- lated donor transplantation. hla disparity and rapid immune reconstitution do not over- come propensity to relapse in patients undergoing haploi- dentical hematopoietic stem cell transplant (hsct)

thomas jefferson university hospital, philadelphia, pa while increasing hla disparity is known to be associated with increased risk of significant graft versus host disease (gvhd), there is less data as to whether increasing hla disparity is corre- lated with stronger, clinically significant graft versus leukemia ef- fects. we examined a group of patients with acute leukemia undergoing haploidentical hsct to assess whether ) there was a marked difference in relapse rates based on the degree of hla mismatch and ) if early recovery of donor lymphoid subpopula- tions was associated with less relapse after hla mismatched hsct. thirty-four adult patients with aml ( ) and all ( ) underwent haploidentical hsct between and using a step process which separates the infusion of the lymphoid and myeloid portions of the graft while attempting to render the lymphocytes tolerant utilizing cyclophosphamide. the patients re- ceived x e /kg donor cd cells (dli) after conditioning with either tbi gy (n ) or fludarabine mg/m � , thiotepa mg/m � , and tbi gy (n ). two days after the dli, all patients received cyclophosphamide (cy) mg/kg � followed by a cd selected donor product. the tbi based regimen was given to % of patients with all and % with aml. we exam- ined relapse rates based on the number of antigen mismatches at a, b, cw, and drb in the gvh direction. there were no discern- able differences based on degree of hla disparity with even the most haplodisparate group exhibiting high rates of relapse when disease was present at hsct. in contrast, the presence of active leukemia at the time of hsct had far more impact on subsequent relapse rates (see table). table . outcomes based on degree of hla disparity antigen antigen antigen antigen mismatch mismatch

total chimerism was greater than % donor-derived at the time of the assessment. for patients who did or did not relapse post hsct the median numbers of lymphoid subsets (cells/ul) were: nk ( - ) vs (

than with any discern- able trend in degree of hla disparity or early immunologic recov- ery. other approaches to treat resistant leukemia are required to substantially improve disease free survival

reimbursement systems for prescription drugs in the nordic countries kristensen fko, sverre jm, holm lb pharmecon as, asker, norway objectives: to elicit similarities and differences in the poli- cies and practices for financing, pricing and reimbursing pre- scription drugs in the often perceived similar nordic countries of denmark (d), finland (f), norway (n) and sweden (s). methods: a review of the four countries’ authorities’ stated policies and practices on the matter were performed through a search of the literature and of the respective authorities’ home- pages. the information was validated through interviews with key personnel of the reimbursement agencies in each country, and the final study reports for the respective countries were reviewed by the same persons. results: all countries have a national health care system financed by taxation. there are dif- ferences in the reliance upon patient co-payment (n %, others – %) and whether financing is a county (s) or national (others) responsibility. all have regulated prices for reimbursed drugs; based either upon international comparisons (n, d) or country-specific decisions (s, f). the criteria used for deciding to reimburse a drug vary between the countries, and reimbursement is practiced differently in several other dimensions: mandatory requirement for pharmacoeconomic analysis (f, n, s), the existence of patient-specific reimbursement systems (d, f, n), product- (s) or indication-based (others) reimbursement, use of graded (f), conditional (n, s) or temporary (s) reimbursement, use of reimbursement contracts (n), and different processes for handling disagreement about decisions. conclusion: the nordic countries all have a national health care system financed by taxation and encompassing prescription drugs, but differ in a number of other dimensions with respect to financing, pricing and reimbursing such drugs. php a systematic review of the european pharmaceutical market and the impact of european union regulation and jurisdiction van ginneken ej, schreyögg j, gericke ca, busse r berlin university of technology, berlin, germany objectives: to examine the impact of the increasing role of the european union (eu) on the european pharmaceutical market, focusing on industry and national policies. to give a sys- tematic overview of the current state of the european pharma- ceutical market as a whole. methods: systematic literature review for the years – , including “grey” sources of information, online databases, european commission docu- ments and european court of justice rulings, relevant journals and systematically tracing back relevant references. results: the eu attempts to liberalise the pharmaceutical market and the realisation of a single european market (sem) came to a stand- still, after some considerable achievements (e.g. marketing authorisation). instead, the eu seems to concentrate on coor- dination of results through the adoption of the so-called g recommendations. eu member states successfully—and inten- tionally—kept control on the issues of pricing, reimbursement, pharmacies and prescribing. over the last years they adapted increasingly convergent measures to cope with rising pharma- ceutical expenditures, without long-lasting cost containment effects. however, recent european case law might prove to have far reaching consequences on the provision of medicines. the european pharmaceutical industry—although profitable—is underperforming compared to the usa, which is blamed on restrictive regulatory frameworks in the member states. con- clusions: the future of the actors in the european pharma- ceutical market is not clear. will it bring more european influence or a strengthening of national influence? in the short term, major change towards a sem seems unlikely, but in the longer term european history showed that major change is pos- sible. it seems clear that much depends on the attitude of member states towards the new approach and the interpretation and influence of european case law. for the european industry, adoption and implementation of g recommendations is of great importance for future competition with us-based companies. php using an italian population database to profile prevalence and costs of chronic conditions yuen ej, maio v, louis dz, rabinowitz c, robeson m, smith kd jefferson medical college, thomas jefferson university, philadelphia, pa, usa objective: individuals with chronic medical illness may have multiple health problems, and are often costly and difficult to manage. this study identifies those with highly prevalent chronic conditions and assesses related health service use and costs in the population of emilia romagna (rer), a large northern italian region. methods: pharmaceutical, hospital, and demographic data from and have been assembled for the entire population of rer ( million). pharmaceutical and hospital tariffs were a proxy for costs. pharmacy and hospital records were used to identify individual morbidity. data included demo- graphic and geographic information, encounter dates, diagno- sis/procedure codes, pharmaceutical information, and health care costs. individuals were classified as having a chronic condi- tion in , and we examined pharmacy and hospital use/costs in . descriptive analyses compared mean and total costs, as well as proportions within the population. results: we iden- tified five highly prevalent chronic conditions: cardiovascular dis- eases (n = , , . % of the population); rheumatologic conditions (n = , , . %); gastric acid disorders (n = , , . %); chronic respiratory illnesses (n = , , . %); and psychiatric disorders ( , , . %). . % of the population had one or more of these five chronic conditions, and these individuals accounted for . % of the pharmacy costs and . % of the hospital costs in the following year. for persons with these five conditions, we also described use and costs by age and gender, residence, and income. conclusions: interest- ingly, one-fourth of the population with selected chronic condi- tions accounted for large proportions of cost and use of health services. the ability to identify those with chronic conditions would help planners and governmental agencies to address health care needs, increase quality of care, avoid unnecessary hospitalizations, and save costs. these types of data can be used to estimate health care financing and risk adjustment models, and profile specific clinical, demographic or geographic sub-groups. php adherence index of performance—a new method and tool for ongoing evaluation of medication adherence improvement initiatives day d pfizer, new york, ny, usa objectives: to develop a

environmental, and marine sciences, rider university, lawrenceville road, lawrenceville, nj, , usa abstract two tulip poplars (liriodendron tulipifera l.) growing at monticello, the home of thomas jefferson, were recently removed because of potential damage to the house; however, their ages were uncertain. jefferson’s writings express his interest in tulip poplars and suggest that he may have planted at least one, but his documents are not conclusive. after the thomas jefferson foundation purchased the property in a.d. , expert opinions on the ages of these trees were divided. this study investigated the ages of both trees (referred to as northwest and southwest). even though the southwest tree’s bole was hollow and decay was present in the northwest tree, usable cross-sections were obtained. the southwest tree’s cross-section was from an upper branch, whereas upper and lower cross-sections were extracted from the bole of the northwest tree. ring widths were crossdated and statistically verified using an oak chronology from monticello. the innermost rings of the southwest tree dated to a.d. and those of the upper and lower sections of the northwest tree dated to and , respectively. these dendrochronological analyses in combination with historical photographs support the conclusion that the northwest tree and likely the southwest tree were jefferson era, but the evidence for the southwest tree is less certain. keywords: monticello, thomas jefferson, liriodendron tulipifera, garden history, southeastern us, agricultural plantation. introduction monticello, located in the virginia piedmont, was the plantation home of thomas jefferson, who in his own words sought to be remembered as the ‘‘author of the declaration of american independence, of the statute of virginia for religious freedom, and father of the university of virginia’’ (jefferson : ). monticello is now classified as a national historic landmark as well as a unesco world heritage site. in , jefferson cleared and leveled the site for mon- ticello and began construction in . jefferson moved into the house in , but continued to build and remodel other parts of the house through (nichols and bear ). he lived there until his death in . while jefferson lived at monticello, he took an active interest in planning the grounds surrounding monticello, notably with the plantings of gardens in as he neared the end of his second term as president (betts and perkins ). using tree-ring dating, the objective of this study is to determine whether two large tulip poplar trees recently removed from the west lawn of monticello date to the jefferson era. these tulip poplars are referred to as southwest and northwest (figure ) following jefferson’s designations for the four shrub circles placed around the main house (jefferson ). jefferson’s own writings attest to his interest in native trees – tulip poplars particularly. in an letter to madame de tessé, jefferson exclaims that only the white oak (quercus alba l.) ‘‘disputes for pre-eminence with the lirioden- dron,’’ calling the white oak the jupiter and the tulip poplar ‘‘the juno of our groves’’ (jefferson : – ). as he planned

[shrub circle] from the nursery’’ (jefferson : ). this entry has led to a historical interpretation that the southwest tree is likely a jefferson-era tree, but no direct link has shown that either tree dates to that time. other contem- porary references to the natural establishment of tulip poplars in the soil at monticello exist in a letter from thomas mann randolph, jr., lamenting the rapid ability of tulip poplars to establish in monticello’s plantation fields and an letter from cornelia j. randolph who mentions the weeding of young poplars from the yard at monticello; however, her letter may refer instead to populus (l.) species that were planted at monticello (jefferson ). tulip poplar seed- lings are still common today in fields adjacent to monticello at montalto where an annual mowing is used to prevent the re-establishment of forests in historically open areas. across their wide range in eastern north america from new york to florida, tulip poplars grow best in deep, moist loam soils within coves or lower slopes and are common on the ultisol soils of the virginia piedmont (burns and honkala ). although originally considered an early successional species, tulip poplars can attain ages of more than years and may be a component of late successional forests as well (skeen et al. ; pederson ). materials and methods the growth of trees in the virginia piedmont can be explained largely as a function of precipi- tation and available solar radiation passing through a forest canopy to a tree (kozlowski ; druckenbrod et al. ). thus, a component of the annual growth of these trees is a common climate signal, typically spring or summer precip- itation (e.g. druckenbrod et al. ). the samples from these two trees are compared to a well- replicated oak chronology extending back to a.d. at monticello with many of the trees growing nearby on the western slopes of monticello. the southwest tree was felled in and the northwest tree in . five radii of tree-ring widths from three cross-sections were analyzed in this study. two radii from an upper cross-section of the southwest tree, one radius from an upper cross- section on the northwest tree, and two radii from a lower cross-section of the northwest tree at ca. m (stump height). the diameter of the northwest tree at stump height was ca. . m (inside bark), noticeably smaller than the diameter of the southwest tree. crossdating using skeleton plots (stokes and smiley ) and ring-width measure- ments was conducted using a dissecting stereo microscope. ring widths were measured using a velmex ta system to a -micron precision (as described in speer ) and the j x measurement program. cofecha was used to verify the visual crossdating of the ring-width data by generating correlations for each sample in -year moving windows (holmes ). samples with poor statis- tical correlation in cofecha were compared with figure . southwest tulip poplar (with cables) in foreground and northwest tulip poplar in background. photograph was taken the day before the removal of the southwest tree (june , ). northwest tree was removed in june . [credit: thomas jefferson foundation, inc. at monticello]. druckenbrod and chakowski skeleton plots to confirm the most accurate possible dating. ring-width measurements from each tulip poplar were converted into separate standard chronologies using the program arstan (cook and krusic ). cores were detrended using either a negative exponential or linear regression fit (with a positive or negative slope) and a -year cubic spline. these chronologies enabled a final correlation of each tree’s average tree-ring indices with a master oak (quercus l.) chronology (n trees) from forests surrounding monticello dating back to a.d. using the spearman rank correlation, a nonparametric measure of similarity between the two chronologies through time. results for each of the five ring-width series (figure ), cofecha generated positive correlations across all -year sample windows; however, the southwest tree had lower correlations than the northwest tree (table ). the earliest ring of the upper section of the northwest tree crossdated to , but the lower radii crossdated to . the upper branch of the southwest tree crossdated to ; however, some of the moving window correlations for these series were low, below a commonly accepted threshold of . for individual series. similarly, an averaged growth chronology of ring-width series from the northwest tree correlated significantly with the local oak chronology (figure a) with a correlation of . (p , . ). the averaged growth chronology from the southwest tree again exhibited a lower, but still highly significant, correlation (figure b) of . (p , . ). as an additional verification, the northwest tree chronology was compared with an independently dated chronology of tulip poplars from an old stand near buena vista, virginia, collected by dr. neil pederson (unpublished data). the correlation between these two chronologies was . (p , . ), even with a large distance between these sites extending into the blue ridge mountains physiographic province. discussion these results clearly evidence that the north- west tree and likely the southwest tree began growing well before jefferson’s death in . although the southwest tree did not crossdate as strongly as the northwest tree, the dendrochrono- logical dating of both trees is extremely unlikely to have resulted from chance. several factors could explain the variation in magnitude of these correlations with the local oak chronology across series and through time. first, the oak species present at monticello are generally more drought tolerant during the growing season and may not respond to interannual climate variation in the same manner as tulip poplars. second, these oaks grew in a closed-canopy forest environment, whereas the two tulip poplars were likely in open canopy conditions and maintained as part of the formal gardens for at least their latter years. finally, perhaps most importantly the southwest poplar’s correlations are particularly low during the early to mid s. this tree was topped around and heavily pruned during the s (thomas jefferson foundation, inc. ). these actions may have induced other interannual growth trends in this tree obscuring the climate forcing on its growth through the mid-twentieth century. independent verification of the age of these two trees was also considered through a compar- ison of photographs, paintings, maps, and letters depicting the conditions of the west lawn of monticello from to the present. to assist in approximating the size of these two trees through time, beck ( ) provides a site index curve for tulip poplars by age in different soil fertilities. the curve shows the range in tree heights for forest- grown, dominant or co-dominant tulip poplars through time based on sites in the virginia and north carolina piedmont. extrapolating from the range of soils on this site index curve, a typical tulip poplar would have grown taller than the top of monticello (ca. . m) by years of age, even on the lowest quality site. most tulip poplars would be taller than m by twenty years of age. the tulip poplars at monticello were growing in largely open conditions, which could reduce the rate of height growth relative to trees in a forest. these two tulip poplars may also be growing on a site that wouldn’t naturally feature this species in a forest. even though tulip poplars readily establish tulip poplars at thomas jefferson’s monticello in the soils as seedlings at monticello, their distribu- tion is limited to largely the north and east slopes of the site. oaks and other species dominate the forests on the south and west slopes of the site. the soils on the top of the site would not have as much soil moisture as those on the north and east slopes and could result in a slower rate of growth for these poplars. two documentary records from the early to mid- th century provide conflicting interpretations of the ages of these two trees. a map of the garden restoration undertaken by the garden club of virginia between – (betts and perkins ; p. – ) labels both of these tulip poplars as original to jefferson’s time (figure ), but earlier in the s an arborist and architect both concluded that these trees post-dated jefferson (thomas jefferson foundation, inc. ). an analysis of photographs of the west lawn of monticello during the th and late th centuries consistently shows these two tulip poplars in their present locations. notably in the early th century, an oblique aerial of the west lawn in the winter of – shows both trees at that time (figure ). at the turn of the th century, these trees remain visible in a holsinger studio collection photograph of the east front of the house taken between and (figure ). the two trees are clearly taller than the house in this image, and the diameter of the northwest tree remains noticeable smaller than the southwest tree even at this early date. this east front perspective is similar to one of the oldest images of the house taken by william roads in (held by the albert and shirley small special collections library, university of virginia). the southwest figure . crossdated ring-width measurements from northwest and southwest tulip poplars sampled in this study. a and b are lower radii and c is an upper radius from the northwest tree, and d and e are upper radii from the southwest tree. druckenbrod and chakowski tree and the faint outline of the northwest tree are also apparent in this image. again, both trees are taller than the house in this image. using the lower cross-section of the north- west tree, one can estimate the size of this tree through time. by the end of , the year of jefferson’s death, the diameter of the tree (as averaged from the two measured radii) inside the bark would have been ca. . cm. by the end of , the year of the roads photograph, the diameter inside the bark would have been . cm. an estimation of the tree’s height in is also possible with an allometric equation. a parabolic equation (h + b d + b d ) from ker and smith ( ) for forest grown trees (see druckenbrod et al. ) requires the tree’s figure . comparison of the northwest tree (a) and southwest tree (b) chronologies (dashed lines) with a local monticello oak chronology (bold line). table . -year moving window correlations for each ring-width series compared against the other four ring-width series from the northwest and southwest tulip poplars growing on the west lawn at monticello. tree series time span – – – – – – – – northwest a – . . . . . . . . northwest b – . . . . . . . . northwest c – . . . . . . . . southwest a – . . . . . . southwest b – . . . . . . tulip poplars at thomas jefferson’s monticello figure . plan of monticello garden restored by the garden club of virginia between and labeling both the northwest and southwest trees as original to jefferson. flower beds and shrub circles are shown in gray, trees with black dots, and original trees are labeled ‘‘ ’’.

additional cm) as well as estimates of maximum height and diameter for tulip poplars. because these param- eters are imperfectly known, this height determi- nation is approximate at best, but this equation suggests that the tree would have been ca. m at the end of . this result agrees with the interpretation of these early photographs in that even the northwest tree would have been notice- ably taller than the house by the time of the roads and holsinger photographs. thus, these photo- graphs provide a consistent documentary record of what appears to be the northwest and southwest trees back to the late s when both trees were still taller than the house. because the southwest tree was hollow at the base, we were limited to sampling a cross-section from an upper branch (with a cable wire attached). comparing its size to the northwest tree and knowing that the branch position was at least as high as the house, it seems likely that the southwest tree is substantially older than the date determined from the upper cross- section. potentially, the greater size of the southwest tree could have also resulted from a more productive soil beneath its position on the west lawn. archaeological analyses of the west lawn suggest that prior to the construction of the house the site was leveled by transferring the a and a portion of the b soil horizons from the northern part of the west lawn (where the northwest tree was growing) to the southern portion (where the southwest tree was growing) (f. neiman, director of archaeology, monticello, personal communication), potentially improving the soil fertility for the southwest tulip poplar at the expense of the northwest tree. the preponderance of the evidence suggests that the northwest tree and the southwest tree likely established during the time that jefferson planned his formal gardens on the west lawn of monticello. no documentary record exists to support the interpretation that jefferson intention- ally planted the northwest tree, as tulip poplars readily establish on mineral soil and documentary evidence suggests that their establishment was pervasive at monticello. regardless of the tree’s origins, jefferson was clearly fond of tulip poplars and appears to have incorporated this tree into his west lawn plan. although dendrochronological dating cannot confirm that the southwest tree is the same as the one mentioned by jefferson in his april , , garden book entry, its size and presence in early photographs also suggest that it was also jefferson era. acknowledgments we thank the thomas jefferson

anion channel isoform (vdac ). here, we show that hcc induced by carcinogenic compounds, aflatoxin or den is highly sensi- tized to tbid-induced omm permeabilization and cyto c release when com- pared to normal liver. expression levels of vdac and bak were also higher in hcc than in control liver. the role of the vdac -bak pathway in the differential tbid sensitivity was validated by overexpression of vdac in primary hepatocytes. in hcc cells, elevation of bak was also associated with an increased level of mcl- , an inhibitor of bak. furthermore, both constitutive and drug-induced genetic deletion of mcl- in mouse embryonic fibroblasts caused sensitization to tbid-induced omm permeabilization in the absence of a change in bcl-xl or bax . based on these results, we are evaluating the possibility of selective killing of hcc cells by the combination of a bak activator and an mcl- inhibitor. -pos board b which domain of vdac is necessary for bak insertion to the outer mitochondrial membrane and tbid - induced cytochrome c release? shamim naghdi , peter varnai , soumya sinha roy , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadlephia, pa, usa, semmelweis university, budapest, hungary. vdac proteins represent a main component of the outer mitochondrial membrane (omm). the vdac family is composed of isoforms with more than percent similarity. although their primary role was known to be in ion and metabolite transport between mitochondria and cytosol, it has been dis- covered that vdacs are also involved in apoptotic pathways. we have recently found that specifically the vdac isoform is needed for tbid-induced cyto- chrome c release, due to its role in supporting bak insertion to the omm (roy et al. . embo rep. : - ). to determine the domain(s) of vdac which supports bak insertion, vdac and vdac amino acid composition compared and the unique attributes of vdac sequencewereconsideredformutationalanalysis.totestfunctionalsig- nificance of the changes in vdac or vdac , vdac -/- mef cells that are resistant to tbid, were transfected with the mutants and insertion of bak to the omm and cytochrome c release were monitored in permeabilized cells by immunoblotting. previously, we showed that the vdac -specific n terminal tail and cysteins are dispensable for tbid-induced omm permeabilization. to approach the remaining differences four chimeras were prepared: vdac ( - )vdac ( - ), vdac ( - )vdac ( - )vdac ( - ), vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ). these studies revealed that tbid dependent omm permeabilization is only sup- ported by vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ), indicating that the first two third of vdac is required and sufficient for bak targeting to the omm and tbid induced cytochrome c release. -pos board b outer mitochondrial membrane protein distribution and function depend on mitochondrial fusion david weaver , xingguo liu , veronica eisner , peter varnai , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary. cells and tissues deficient in mitochondrial fusion have been shown to have defects linked to the exchange of inner membrane (imm) and matrix compo- nents, particularly mitochondrial dna. outer membrane (omm) constituents originate in the cytoplasm, thus the role of intermitochondrial transfer of omm components by fusion remained unexplored. here we show that fibro- blasts lacking the gtpases responsible for omm fusion, mfn / , have a more heterogeneous distribution of omm proteins than wild-type cells, and in partic- ular that heterogeneity of pro-apoptotic bak leads to dysregulation of bid- dependent apoptotic signaling. homogeneous distribution of bak is partially rescued by introduction of mfn into mfn / -/- cells. furthermore, fusions be- tween mitochondria lacking and containing bak result in hybrids sensitive to bid. proteins with different modes of omm association display varying degrees of heterogeneity in mfn / /- cells and different kinetics of transfer during fusion in fusion-competent cells. efficient coupling of omm to imm fusion depends on the presence of both mfn isoforms and is antagonized by the mitochondrial fission protein, drp . thus, omm function depends on mitochondrial fusion and is a locus of dysfunction in conditions of fusion deficiency. -pos board b mitochondrial fusion dynamics in skeletal muscle of healthy and diseased rat veronica eisner , guy lenaers , gyorgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, inserm u- , institut des neurosciences de montpellier, montpellier, france. mitochondria are highly mobile and dynamic organelles in many cell types. however, in the muscle, mitochondria are crammed into the narrow space among the myofilaments. until now, it remained unclear if mitochondrial fusion occurs in and supports the contractile activity of skeletal muscle (sm). here we applied mitochondria matrix-targeted dsred and photoactiv- able gfp to study mitochondrial fusion in rat fdb sm fibers. in vivo electro- porated fibers were imaged by confocal microscopy. when we tagged the mitochondria in ~ % of cell area with twophoton photoactivation of gfp, rapid spreading of fluorescence showed subsets of interconnected mitochondria, mostly in longitudinal direction. matrix fusion occurred with a rate of . and . events/min in adult fibers and skeletal myotubes, respectively. expres- sion of autosomal dominant optical atrophy-causing mutants of the fusion protein opa or ethanol exposure caused suppression of fusion, which is fol- lowed by mitochondrial dysfunction and late onset myopathies. when chal- lenged by repetitive tetanic stimulation, ethanol exposed cells displayed intracellular ca þ dysregulation, appearing as a fatigue pattern. ethanol also induced a decrease in mfn protein levels, without significantly altering mfn , opa or deltapsi. depletion of mfn alone was sufficient to suppress mi- tochondrial fusion in fdb fibers. fusion inhibition was apparent before any cell dysfunction, suggesting that suppression of fusion is not secondary to other problems in the cells. to directly test the role of mfn in ca þ regulation, ryr -transfected control and mfn ko mefs were stimulated with caffeine. mfn ko cells showed oscillatory ca þ transients that decayed faster than that in the control. thus, fusion dynamically connects skeletal muscle mito- chondria and serves as a target mechanism of both mutations and environmen- tal cues to cause impaired excitation-contraction coupling. -pos board b bcl- proapoptotic proteins distribution in u- mg glioma cells before and after hypericin photodynamic action katarina stroffekova, lucia balogová, mária maslaňáková, lenka dzurová, pavol mi�skovský mi�skovský. safarik university, kosice, slovakia. apoptosis is a key process in the development and maintenance of tissue homeostasis. this process of controlled cell death is tightly regulated by a balance between cell survival and damage signals. we focused our attention towards the intrinsic mitochondrial apoptotic pathway, where bcl- family of proteins plays the major role. we were particularly interested in two pro- apoptotic players bak and bax. here we investigated their role in apoptosis triggered by photodynamic action. we show the localization of bax and bak in u- mg human glioma cells incubated with photosensitizer hypericin (hyp) before and after photodynamic action. apoptotic stimulus by hyp photodynamic action caused bax translocation into mitochondria. however our results suggest that under these condi- tions there are two populations of mito- chondria: one which contains bax and bak simultaneously, and is almost exclu- sively localized near the plasma mem- brane; the other which contains bax only and is distributed throughout the cell. the different protein content and spatial distri- bution of these two populations suggest that they can play different roles in re- sponse to apoptotic stimuli. -pos board b stimulation of bax mitochondrial localization by bcl-xl thibaud renault , oscar teijido , gisele

mitochondria through protein-protein interactions between the bcl- family proteins. an imbalance of this interaction network due to the up-regulation of the proto-oncogenes bcl- and/or bcl-xl lead to a resistance to apoptosis and is associated with tumor formation. bcl-xl overexpression act at the level of the mitochondrial outer membrane (mom) by inhibiting bax-mediated apoptosis; more particularly mac formation and cytochrome c release. how- ever, the molecular mechanisms through which bcl-xl affect earlier steps of bax-mediated apoptosis are not fully understood. surprisingly, we found that mitochondrial bax redistribution and change of conformation were not inhibited but rather spontaneously increased in response of bcl-xl overexpres- sion. in order to further investigate the molecular mechanisms involved in this wednesday, february , a effect, different bax and bcl-xl mutants were co-expressed in yeast. we found that wild-type bcl-xl increased the mitochondrial localization of bax; but that this effect was lost when bcl-xl mutants unable to physically interact with bax were expressed instead of wild-type bcl-xl. also, bax retrotranslocation from mitochondria to cytosol was also increased; suggesting that both translocation and retrotranslocation events were differentially stimulated by the expression of wild-type bcl-xl. further, a c-terminally truncated mutant of bcl-xl, that lost its capacity to relocate to mitochondria, still increased the mitochondrial localization of and cytochrome c release activity of wild-type bax. finally, wild-type bcl-xl protected activated bax against proteolytic degradation. these data suggest that bcl-xl, by acting as a modulator of mitochondrial bax localization, may play an active role along the pathway leading to bax activation. -pos board b mitochondrial dna nucleoid redistribution after mitochondrial network fragmentation as visualized by d super-resolution biplane fpalm microscopy andrea dlaskova , tomas

department of cell biology, yale university, new haven, ct, usa. mitochondrial (mt) network undergoes locally frequent fragmentation and fusion events. when integrated over time, its basic morphology encompasses highly interconnected mt reticulum, a single mitochondrion within the cell ( ). upon certain insults and/or pathological states fragmented network persists. mtdna is organized in nucleoids containing assessor proteins and recruited proteins of mt replication/ transcription machinery. it is debated on their uniform size and whether a single nucleoid contains a single mtdna mol- ecule or up to average mtdna molecules. to image nucleoid distribution within mt network, we employed d super-resolution fluorescent photactivable localization microscopy of biplane schema ( ). mt network of hepatocellular carcinoma hepg cells was imaged first by its matrix space using mteos or as outer mitochondrial membrane contour using eos -conjugates of truncated fis protein (not inducing massive fission, eos -fis tr). resulting d images confirm the existence of highly-connected mt network and unlike conventional confocal microscopy, d biplanefpalm distinguished a hollow character of mt reticulum tubules when visualized by eos -fis tr. upon network fragmen- tation, hollow max ~ micrometer spheres occurred. imaging of mt nucleoids confirmed the existence of ~ nucleoids per cell with size distribution from nm to nm. optimized dual transfection strategy had to be em- ployed for simultaneous imaging of network (mteos or eos -fis tr) and nucle- oids (mtssb-pscfp ). images revealed an equidistant nucleoid distribution of an average distance of ~ micrometer between nucleoids. fragmentation by different agents led to observations of clusters of mt nucleoids within the spher- ical fragmented objects thus formed. supported by grants p / / , p / /p and p / / of gacr and me (czech ministry of education); and r gm - (nih).

metabolic networks: a two-compartment model jackelyn m. kembro, miguel a. aon, raimond l. winslow, brian o’rourke, sonia cortassa. johns hopkins university, baltimore, md, usa. to understand the mechanisms involved in the control and regulation of mito- chondrial reactive oxygen species (ros) levels, a two-compartment computa- tional mitochondrial energetic-redox (me-r) model accounting for energetic, redox and ros metabolisms is presented. the me-r model incorporates four main redox couples (nadh/nad þ, nadph/nadpþ, gsh/gssg, trx(sh) / trxss). main scavenging systems - glutathione, thioredoxin, superoxide dis- mutase, catalase - are distributed in mitochondrial matrix and extra-matrix compartments, and transport between compartments of ros species (superox- ide: o .- , hydrogen peroxide: h o ), and gsh is also taken into account. model simulations are compared with experimental data obtained from isolated heart mitochondria. the me-r model is able to simulate: i) the shape and order of magnitude of h o emission and dose-response kinetics observed after treatment with inhibitors of the gsh or trx scavenging systems; and ii) steady and transient behavior of djm and nadh after single or repetitive pulses of substrate- or uncoupler-elicited energetic-redox transitions. the dynamics of the redox environment in both compartments is analyzed with the model fol- lowing substrate addition. the me-r model represents a useful computational tool for exploring ros dynamics, the role of compartmentation in the redox environment modulation, and the role of redox regulation in the control of mi- tochondrial function. -pos board b dj regulates neuronal mitochondrial bioenergetic efficiency elizabeth a. jonas, emma lazrove, panah nabili, kambiz n. alavian. yale university, new haven, ct, usa. the progressive loss of midbrain dopaminergic neurons is the hallmark of parkinson’s disease (pd). defects in mitochondrial electron transport and mitochondrial dna replication predispose to the onset of pd. the protein products of several pd genes, including parkin, pink and dj are known to localize to mitochondria; pathological mutations in these genes may disrupt mitochondrial function. in a previous study we found that the anti-apoptotic pro- tein bcl-xl enhances the efficiency of neuronal energy metabolism by increasing total cellular atp levels while decreasing cellular oxygen use. bcl-xl produces this effect in part through a direct interaction with the beta sub- unit of the f fo atp synthase. the interaction causes a decrease in leak of hþ ions across the mitochondrial inner membrane, correlated with an increase in coupling of oxidative phosphorylation. we now show that the parkinson’s dis- ease gene-encoded protein, dj (park ), is also associated with the atp syn- thase complex and has a similar regulatory effect on enzymatic activity of the synthase and on the coupling of oxidation to phosphorylation. pathological mutations of dj may disrupt mitochondrial efficiency leading to neurodegen- eration of mesencephalic dopaminergic neurons. the exact site of the leak inhibited by bcl-xl and dj is now being determined, but likely resides in or adjacent to the c-subunit ring of the atp synthase fo. improved mitochondrial metabolic efficiency that accompanies decreases in h þ leak may result in long lasting changes in synaptic efficacy and survival in both healthy and at-risk neu- rons, suggesting a role for leak regulation in future therapeutic interventions. -pos board b identification of mitochondrial proteins regulated during activation of gper -leading to cardioprotection jean chrisostome bopassa , rong lu , harpreet singh , bjorn olde , l.m. fredrik leeb-lundberg , ligia toro , enrico stefani . university of california los angeles, la, ca, usa, lund university, lund, sweden. several studies have demonstrated that g-protein coupled estrogen receptor (gper ) can directly bind to estrogen and mediate its action. we previously demonstrated that gper activation with g , a specific agonist is cardioprotec- tive in wild-type (wt) mice subjected to ischemia/reperfusion injury. here, we identified regulatedmitochondrial proteinsassociated with gper activationby estrogen treatment in wt and gper -/- mouse hearts after ischemia/reperfu- sion. isolated hearts from male wt (c bl/ ncrl) or gper -/- mice were perfused using the langendorff technique with krebs henseleit buffer, with and without (control) the addition of estrogen ( nm). hearts were subjected to min global ischemia followed by min reperfusion. mitochondria were isolated, and d-dige followed by mass spectrometry was performed. proteins of interest were the ones (up-or down- regulated)in wtþe vs. wt-controlthat remained unchanged in gper-/-þestrogen vs. gper-/–control and wt-control vs. gper-/–control.robustchangesofproteinswereobservedin spots,outof which were down regulated and up regulated. in these spots, unique proteins were identified. among the proteins identified, estrogen treatment in- duced the regulation of enzymes mostly involved in electron transfer chain and atp production. estrogen action involved the down-regulation of filament proteins(filamina,b,c),the up-regulationofproteinsthatactivatetranscription, and proteins involved in the contractile system (tropomyosin and myosin). further, estrogen treatment is associated with regulation of proteins acting in stress (stress- protein, and kda heat shock protein), in cell communication (glial fibrillary acidic protein), and in signaling pathways (membrane-associated phosphatidylinositol transfer protein). finally, estrogen down-regulated the mitochondrial inner membrane protein, this protein controls mitochondrial cris- tae morphology. in conclusion, rapid estrogen effects through gper activation are associated with the down- or up-regulation of mitochondrial and non- mitochondrial proteins likely in close contact to mitochondria. -pos

. ; p < . ) (figure ) (table ). although all complica- tions of diverticulitis appear to preferentially affect white individuals more than black individuals, this trend is least pronounced with hem- orrhage in the setting of diverticulitis (figure ) (table ). in other words, hemorrhage had the highest proportion of black individuals of all diverticulitis complications at . % which is significantly higher than the general population of philadelphia (or = . ; % ci = . - . ; p < . ). age and gender patients admitted for diverticular bleeding tend to be older ( . ± . ) than patients admitted for diverticulitis ( . ± . ; p < . ). among those with complicated diverticulitis, patients with hemorrhage are the oldest ( . ± . ) by at least years (average age of . ± . years for obstruction) and at most years (average cause of hospitalization for diverticular disease[ ], it accounts for up to % of lower gastrointestinal bleeds requiring hospital admission[ ]. unlike diverticulitis, diverticular bleeding is typically not associated with inflammation. instead, diverticular bleeding is likely due to a combination of thinning of the colonic wall increasing the proximity of vessels to the colonic lumen as well as inherent segmental weak- ness in arteries supplying diverticula secondary to structural changes associated with the development of diverticulosis[ ]. this can lead to spontaneous rupture of arteries supplying a diverticulum producing a painless, often self-limiting hematochezia[ ]. though bleeding re- solves in - % of patients without intervention[ , ], bleeding which does not resolve may require endoscopic, endovascular, or surgical correction to prevent complications[ , ]. even for those for which bleeding resolves spontaneously, there is still up to a % chance of rebleeding[ ]. other than recurrent bleeds and potential need for intervention during episodes, diverticular bleeding is typically not as- sociated with long-term complications which often manifest in other forms of diverticular disease, such as diverticulitis. diverticulitis itself has many complications which make it the most severe and life-threatening form of diverticular disease[ , ]. acute diverticulitis is thought to be caused by microperforations in diverticula producing diverticular inflammation which presents as se- vere abdominal pain most commonly localized in the left lower quad- rant[ , ]. the most common complication of acute diverticulitis is ab- scess formation caused by the walling off of material which egressed from diverticular microperforations into adjacent pericolonic fat and mesentery[ , ]. the inflammation of diverticula and pericolonic tis- sue can additionally produce partial obstruction through ileus and colonic narrowing as well as fistulas between the colon and adjacent organs[ ]. lastly, while diverticular bleeding is a separate disease process from diverticulitis, complicated diverticulitis can present with hemorrhage due to irritation of surrounding microvasculature in the area of inflammation[ ]. lower gastrointestinal hemorrhage in a patient presenting with diverticulitis is a defining symptom that shifts the diagnosis from un- complicated diverticulitis to complicated diverticulitis[ ]. because of higher mortality risks associated with complicated diverticulitis and the need for closer monitoring, this shift could mean the difference between conservative outpatient management with little to no antibi- otics and inpatient admission with more aggressive treatment involv- ing intravenous antibiotics and expensive imaging[ ]. the pathophys- iological basis of diverticulitis and diverticular bleeding is not well understood and controversy remains regarding their etiology. this study sought to determine the demographic characteristics of patient populations hospitalized with diverticular bleeding and complicated diverticulitis with a focus on a distinction between hemorrhage in the setting of diverticulitis and diverticular bleeding. methods design a retrospective cross-sectional study was used to determine patterns of hospital admissions for diverticular disease, diverticulitis, and di- verticulitis complications in philadelphia between january and december . data was obtained from the pennsylvania health care cost containment council which collects more than . million inpatient discharge records each year from pennsylvania hospitals. the dataset includes admission characteristics with one primary and up to eighteen secondary diagnosis codes as well as patient charac- teristics including age, gender, zip code, race, and ethnicity. approval was obtained from the institutional review board prior to data french b et al . redefining hemorrhage in diverticulitis abscess perforation hemorrhage obstruction fistula us census philadelphia diverticular bleeding diverticulitis uncomplicated diverticulitis complicated diverticulitis us census philadelphia age of . ± . years for abscess). there was no significant dif- ference in gender distribution between diverticular bleeding and di- verticulitis or any of its complications, all of which showed a female predominance (table ). discussion it is well documented that of the manifestations of diverticular dis- ease, those presenting with diverticular bleeding tend to be older than those with diverticulitis[ , ]. while the peak age for diverticulitis in our data is around years of age, there are almost no cases of diver- french b et al . redefining hemorrhage in diverticulitis table total number, average age (+/- s.d.), and number/percentage f e m a l e g e n d e r o f h o s p i t a l i z a t i o n s w i t h d i v e r t i c u l a r b l e e d i n g , diverticulitis, and diverticulitis complications in philadelphia from -

]. especially in philadelphia where profound racial healthcare inequality exists, black individu- als are more likely to be on long-term anticoagulation or aspirin due to the increased disease burden including hypertension, dvts/pes, and diabetes disproportionately affecting this segment of the popula- tion[ - ]. similarly, patients > years old are more likely to be using antithrombotic medication as older age is a risk factor for almost all vascular disease manifestations[ , ]. this consideration is important for a physician to bear in mind when treating patients with concurrent coagulopathies and diverticular disease so as to minimize the risk of hemorrhage while maximizing the anticoagulation effects. with shifts towards conservative outpatient management of un- complicated diverticulitis, there is a widening gap between the level of treatment administered for uncomplicated and complicated di- verticulitis cases[ ]. many uncomplicated diverticulitis episodes are treated outpatient with physicians forgoing antibiotics and imaging in favor of reducing the cost burden associated with this disease[ - ]. by classifying hemorrhage as a complication of diverticulitis, patients are exposed to potentially unnecessary antibiotics and imaging that they otherwise might not receive. the results of our study suggest hemorrhage in the setting of diverticulitis is more likely to be closer in etiology to diverticular bleeding than diverticulitis based on patient demographics and therefore should prompt changes in treatment para- digms surrounding this clinical presentation. by prioritizing treatment protocols for diverticular bleeding rather than complicated diverticu- litis, patients may receive more appropriate treatment while avoiding extraneous tests and medications for what would otherwise be consid- ered uncomplicated diverticulitis. in this way, a reclassification of di- verticulitis complicated by hemorrhage as uncomplicated diverticulitis with superimposed diverticular bleeding may reduce the cost burden associated with this disease as well as prevent potentially harmful ef- fects of unnecessary broad-spectrum antibiotics and imaging. overall, patients admitted with diverticulitis complicated by hemorrhage are more similar demographically to patients admitted with diverticular bleeding than those admitted with other forms of diverticulitis. because prior studies have suggested that demographic differences between diverticular bleeding and diverticulitis suggest distinct etiologies, we conclude that hemorrhage in the setting of di- verticulitis should be treated as a diverticular bleed and not as a com- plication of diverticulitis itself. if these patients were diagnosed with uncomplicated diverticulitis with diverticular bleeding instead, this could lead to a reduction in length of stay and prompt more appropri- ate treatment with greater focus on hemodynamic stability, a higher threshold for administering antibiotics, and avoidance of unnecessary imaging. references . milenkovic m, russo ca, elixhauser a. hospital stays for gas- trointestinal diseases, : statistical brief # . sep. in: healthcare cost and utilization project (hcup) statistical briefs [internet]. rockville (md): agency for healthcare research and quality (us); feb.

and valerie s. ganetsky, pharmd, bcps and for their re- sponse to our article evaluating a diabetes group medical visit (gmv) and for sharing their experience implement- ing a diabetes shared medical appointment (sma). we applaud their implementation of an ongoing diabetes sma. as the authors illustrate, the terminology for these types of group visits (gmv vs sma) varies. however, the terms are ultimately interchangeable; both refer to group visits that incorporate medical care and group self-man- agement education. , while our program has a different structure than that of drs. kaufman and ganetsky, we do want to clarify that our participants have opportunities to interact and support another during the diabetes self- management education component of our gmv. in fact, an earlier study of our diabetes gmv, consisting of interviews with former participants, showed that a sub- stantial proportion of participants found that the pro- gram offered peer support and important opportunities to learn about diabetes self-management from their peers. in addition, we agree with the authors’ call for na- tional best practices for group visits, a national working group, and national conferences focused on group visits and other care delivery innovations. while diabetes group visits hold promise as a patient-centered approach to chronic disease management, more research is needed to identify the optimal group visit size, frequency, struc- ture, and payment mechanisms that will make these visits effective and sustainable in primary care practices. amy t. cunningham, phd, mph department of family and community medicine, thomas jefferson university, philadelphia, pa to see this article online, please go to: http://jabfm.org/content/ / / .full. references . cunningham at, delgado dj, jackson jd, et al. evaluation of an ongoing diabetes group medical visit in a family medicine practice. the journal of the american board of family medicine. ;

when a test is done, there’s often a prior reason to suspect some irregularity, and published frequencies from these sources range from % to over % [ ]. dna-based kinship analysis is also used in the contro- versial practice of familial searching, where a crime- scene dna profile is used to search a database for pro- files sufficiently similar to derive from close relatives; siblings, for example, are expected to share on average half of their dna by descent. familial searching has been most used in the uk, and has had some famous successes. craig harman was convicted of manslaughter after his profile on a brick led police to his brother, and thence to him. serial rapist david lloyd’s dna profile picked out that of his sister, who entered the national dna database following a driving offence. ethical objections have been raised, because familial searching increases police interest in individuals based purely on their relatives’ previous contact with the criminal justice system, but nonetheless the method seems to be catch- ing on [ ]. we proposed another controversial way of discovering suspects from crime-scene dna, by predicting their sur- names from a large database of y-str profiles and asso- ciated names [ ]. forensic databases of this kind do not yet exist, but genetic genealogy companies maintain publicly accessible databases with many tens of thou- sands of entries (e.g. http://www.ysearch.org). how well it would work would depend on the simplicity of the link between ancestral founders of heritable surnames and their modern descendants. for some rare surnames, among them attenborough, it is simple - over % of apparently unrelated attenborough men share a y hap- logroup, and a set of closely related y-str haplotypes [ ]. if we assume that the common y type descends from the original mr attenborough when the name was founded about years ago, and that the other y lineages are due to non-paternity events, then this allows us to calculate an average non-paternity fre- quency of - % per generation. jeffersons, however, are not like this. among unre- lated men with this surname there are many different y chromosome types, reflecting as many as different possible founders. but much to their surprise, two unre- lated english jeffersons share the rare hg t a* haplotype with the president [ ]. luckily, these distant relatives link thomas jefferson to britain within the last few cen- turies, rather than to the heartland of haplogroup t, the middle east, thus defusing yet another possible mystery story about the celebrated figure on the $ bill. received: october accepted: october published: october references . gordon-reed a: thomas jefferson and sally hemings: an american controversy. charlottesville, va: university press of virginia;

and some things that may not in equal amplitude be found elsewhere. the case is doubtless the same with other individuals whose public lives have extended thro' the same long & pregnant period. it has been the misfortune of history, that a personal knowledge and an impartial judgment of things rarely meet in the historian. the best history of our country therefore must be the fruit of contributions bequeathed by contem- porary actors & witnesses, to succes- sors who will make an unbiassed use of them. and if the abundance & au- thenticity of the materials which still exist in the private as well as public re- positories among us shd. descend to hands capable of doing justice to them, the[n] american history may be ex- pected to contain more truth, and les- sons, certainly not less valuable, than that of any country or age. significantly, the last sentence from this madison quotation appeared on the title page of the national historical publications commission's re- port. implied was that the commission considered itself the beneficiary and executor of madison's trust and that it shared madison's faith in the para- mount value and instructive power of american history. the same sense of historical self-importance and special mission of spreading the "truth" has descended from madison's time to our own. as jesse lemisch pointed out eight years ago, the inception of the current program of modern, scholarly historical editing projects in the early gaillard hunt, ed., the writings of james madison, vols.

[which required] no manipulated or authoritarian pattern of interpreta- tion." t h e preservation and publi- < cation of presidential papers as a sym- bol of the openness of american society was made explicit by one of the editors of these projects at about the same time as the commission report. lyman h. butter field wrote that these activities will guarantee historians the means of re-creating whole men and essential keys to the whole truth about their periods of activity on the american scene. i know comparatively little about librar- ies and archives in soviet russia, but i have not heard of a library built to house the papers of joseph stalin and to make them available in orderly stages to scholarly investigators. nor would i be inclined to trust any com- pilation of his papers or biographical or monographic work on stalin until these things are done. such expressions reflect madison's assumption that later generations of historians, because of their detach- ment, would write "impartial" and "unbiassed" history based on the manuscripts of public men such as himself. t h e conviction that "the whole truth" could be derived from such sources paralleled madison's belief that the american history written from these materials would contain great truths and lessons. t h e self-conscious preservation and transferral to poster- ity of their papers by the public "actors & witnesses" of madison's genera- tion were indicative of a keen appreci- ation of their own historical impor- tance. this emphasis on individuals jesse lemisch, "the american revolution bicentennial and the papers of great white men," aha newsletter (nov. ): - , passim. national historical publications commission, a national program for the publication of historical doc- uments: a report to the president by the national historical publications commission (nhpc: washington, d.c., ), p. . see also lester j. cappon's review of volume ofthe papers ofthomas jefferson, in the journal of southern history (hereafter cited asjsh). cappon says: "national and world-wide issues of the mid-twentieth century have reawakened an appreciation of his [jefferson's] kinship with free men in their struggle against bigotry and tyranny in many forms."

and its belief that "these editions will endure because they are above suspicion of partisanship and because in their in- clusiveness they anticipate the chang- ing interests of future historians" is highly questionable. not the commis- sion itself so much, but its expression of a widely held assumption that these projects are value-free and exist out- side of the continuum of american historiography deserves scrutiny. of course the commission's activities and the editing of these volumes promote the study of history, and a particular kind of history, usually centered around a single figure of public prom- inence. as one reviewer has said, "the enormous investment of professional financial resources in such projects is a continuing reaffirmation of belief, even faith, in the towering importance of bi- ographical study in the pursuit of un- derstanding of the past." involved also is the writing of his- tory; hardly any of these editions claim to be publishing volumes devoid of his- torical interpretation. and the history written in them has at times revealed limited perspective, outdated histo- riography, or careless scholarship of the editors. the papers of james iredell, particularly, has come under heavy at- tack for poor editing, inaccurate texts, and outmoded and superficial, or else silent, treatment of issues of current historiographical interest. such criticism points to one of the distinguishing characteristics of these modern editions: the historical notes written around the documents. these emendations have come to be expected in the editions, but have also become a focal point of controversy about them. almost thirty years ago, with his review of the first volume of the papers of thomas jefferson, lester cap- pon heralded the beginning of the era of comprehensive, scholarly editions. he singled out as particularly notewor- thy julian boyd's editorial notes for being "gems of historical criticism, as interesting and provocative as the n h p c , a report to the president, p . . ibid., p . . t h o m a s b. alexander, review of the papers of andrew johnson, vol. , in jsh ( ): . reviews of the papers of james iredell, vols. - , by philander d. chase, in american historical review (hereafter cited as ahr) ( ): ;

the notes should ex- plicate the documents, not improve upon them. brooke hindle, review of the papers of benjamin franklin, vols. - , injah ( - ): - . william b. willcox, the editor, has been roundly criticized on all of the points mentioned in the preceding paragraph. j. a. leo lemay, in his review of vol. , said that "at its worst, it is a deliberately selected edition, rather than a complete one, of unsound texts, full of officious editorializing" (ahr [ ]: ). see also david ammerman, review of vol. of the same, in ahr ( ): - . brooke hindle, review of the papers of benjamin franklin, vols. - , injah ( - ): . /sh ( ): . most notably, the papers of daniel webster. see reviews by maurice g. baxter, of vol. , in jah ( - ): ;

the current madison project has to publish almost thirty-five years of his life before it reaches this letter. to varying degrees many of the projects are in a similar state of arrears. as put by leonard levy, "these volumes are being edited for posterity, and their publication will probably continue un- til their audience arrives." this wave of condemnation against the elaborateness and costliness of the projects had reached its peak by . the protest markedly subsided there- after. extensive editorial apparatus be- gan to be praised again and little com- for the papers of john c. calhoun, see john a. munroe's comment that calhoun "remains a non- person, an office," in his review of vol. , in jah ( - ): . see also his reviews of vols. and - , in mvhr ( - ): , and jah ( - ): ;

"a marked renaissance of interest in history, and especially in historical sources" has been announced. the papers projects could be promoted as popular reading. they were hailed "as monuments to the two hundredth an- niversary of independence"; they would remain "long after the lesser and grosser aspects of the bicentennial are deservedly forgotten." the view of the modern historical editions as monuments which would last for generations has recurred with the birthday of the revolution which projected the authors of these docu- ments into fame and history. but the current complacency with the course pursued by most editing projects ig- nores the "crisis" which hindle and others perceived in the early s. the problems, however, remain unre- solved. as peter shaw said, "the guard- ians of our tradition have succeeded in keeping it out of print." that this is so can be traced back to madison's be- quest. modern "scholar-editors" seem to continue to feel that madison's trust has descended directly on them, that they are executing the charge of un- biased use of the documents and of purveying the truth. in the process of doing justice to our documentary in- heritance, ever more money, more time, and more detailed historical exe- gesis of the texts has been rationalized. it is time to stop, as hindle urged, and, further, to recognize that these proj- ects are not like the great cathedrals. not only should they not take centu- ries to be completed, but also they may not and perhaps should not endure that long. george m. curtis iii, in his review oithe diaries of george washington, vols. - , praised them "as a monument to creative editing." he acknowledged that "the new washington project is vulnerable to criticism from those seeking greater economies in publication or heavier emphasis upon lesser known figures." however, curtis appeared to think it inconsequential that thousands of dollars and a decade of effort were spent to publish two volumes of washington's diaries which had been pro- duced in a complete and unbowdlerized edition fifty years before (ahr [ ]: ). for a critical review of the same on these issues, see mary beth norton in jah ( ): - . her review, which would have been unexceptionable a few years ago, stands out among current reviews for its hostile stance toward the new edition. the recent increase in laudatory reviews may be partly attributable to the numbers of reviewers who are themselves editors. with a few exceptions, rather than being more exacting of colleagues in their own field, they are less so than historians generally. perhaps this is because historical editors are still on the defensive within the historical profession and prefer not to bring adverse attention to historical editing. among the reviewers cited here, philander d. chase, charles cullen, george m. curtis iii, e.james ferguson, don higginbotham, james h. hutson, merrill jensen, ralph l. ket- cham, and robert a. rutland all have been or are historical editors. the author of this article also must be counted among them. several reviewers have welcomed the publication of first volumes of the newer projects as auspi- cious events of the bicentennial. see for instance, j. edwin hendricks, review of the letters of delegates to congress, - , vols. - , injsh ( ): - ;

to con- sider them, like any other work of his- tory, as a project of a particular generation out of whose values they evolved. a number of alternatives have been suggested or are being tried. sev- eral approaches seem viable. one would be to follow the suggestion of hindle and the practice of the papers of joseph henry and the papers of daniel webster: publish an exhaustive micro- film edition of the papers accom- panied by selective, extensively anno- tated, topical, letterpress volumes. another would be, as proposed by charles sellers and joseph ernst, to collect copies of all the manuscripts in one place and produce a well-indexed and complete microfilm publication of the documents. another idea, ap- butterfield and boyd, eds., historical editing in the united states, pp. - , - , and ;

the stand- ard, once set, has become increasingly difficult to depart from. the distorted perception of priorities has inhibited the trial of divergent methods and di- verse types of projects. attention and money ought to be diverted to the preservation of records which are in danger of perishing altogether. the aim should be to make available in one form or another, to a wider audience, authentic and inexpensive reproduc- tions of as great a variety of manu- script collections as possible. more imagination and effort should be devoted to new kinds of projects. for instance, many state archives con- tain large bodies of petitions which could be grouped chronologically and topically. they would provide a mar- velous source of social and political his- tory and a means of getting at the "in- articulate" of our past. another see robert a. rutland, et al., eds., the papers of james madison, vols. to date (chicago: univer- sity of chicago press, -), : n., n., and : - nn., , - , ;

and by linda k. kerber (see n. , above). in recent years, nhprc has broadened its scope. the commission responded to criticism by new left historians, of the elitism of the original editing projects and to the increased interest in pluralism in the american past. the redefinition of nhprc's mandate, from the publication of the papers of america's great statesmen to the preservation and publication of records and papers of a wider range of subjects, reflected the change in political climate and the shift of interests in the scholarly world. by the expansion in the types of projects, the records and publications programs have come to include women, blacks, other ethnic minorities, reform and labor movements, as well as men notable in polit- ical, scientific, or cultural realms. but when the lists of projects are scrutinized, the numbers and appropriations are still heavily weighted in favor of exceptional individuals or groups, and prominent institutions. the commission's support for the preservation and cataloging of local and state records is com- mendable; let us hope that more money and imagination will be expended in developing other and less accessible records concerning common people and less well-known institutions. the other impor- tant shift in nhprc's emphasis has been to projects more modest in scale and expense. the most impressive fact still remains that the bulk of nhprc's support has gone to the "great, comprehensive historical enterprises" which continue to consume disproportionate time and money in ratio to their productivity and utility (see national historical records and publications commission, report to the president [nhprc: washington, d.c., ], pp. i, v-vi, - , and - , passim). d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .j u hh by c arnegie m ellon u niversity user on a pril the american archivist/ winter source, fast disappearing, are the retir- ing railwaymen who have worked on this country's railroads for the last forty or fifty years. a wealth of docu- mentation could be provided through the collection and preservation of oral histories of the men and of the institu- tional records of the companies and unions. the ongoing projects ought to devote more energy to publishing the documents and less to the writing of history in the form of annotation. as expressed by e. james ferguson and robert mccolley, there seems to be in operation "some undiscovered law about historical editing that would re- late the duration of the project to the growth of editorial apparatus," which in turn takes over the project and all but submerges the actual pa- pers from view. if the effect of this law is not reversed, these projects will be consigned to the fate described by tristram shandy: when a man sits down to write a his- tory, . . . if he is a man of the least spirit, he will have fifty deviations from a straight line to make with this or that party as he goes along, which he can no ways avoid. he will have views and prospects to himself perpetually solic- iting his eye, which he can no more help standing still to look at than he can fly;

just a dream”). immortal memory the mournful lyrics of clanton’s ballad tell of attempts to drown-out thoughts regarding an impossible relationship, along with counter-thoughts suggesting impractical romanticism. orwell’s sub-plot involving the creation of a dictionary is about redacting words so that they cannot be used to establish a true account of the past. the word ‘interregnum’, when applied to actual events that took place in the british isles between the years to , creates a spurious alternative romantic account of monarchical lives lived, and it was invented to support a manipulative political agenda which resonates into political lives lived, today. when used in this context, the word ‘interregnum’ might be better suited to the title of a novel, or even to the lyrics of a pop song in which “any resemblance to real persons, living or dead is purely coincidental ”. if lives lived are rooted in the oxymoron of ‘corrupted factuality’, then it is no wonder that life on this planet seems to be a game of chance where nothing is certain, because nothing can ever be certain concerning all of the events of today which are in turn based upon events that took place yesterday. as individuals, we are limited in our first-hand observations, and what we perceive may not be a true interpretation of an actual event. distortions abound when we as individuals have to rely upon the recall of others, if their observations are preserved in the written word (nef ) . in a legal setting, even first-hand observations are not necessarily reliable guides to what a person may think they have just observed . however, the laws which govern society today are all rooted in past precedents which have all been “written down” (nef ) . therefore, it is well to recall emerson’s observations about the past: "all history becomes subjective; in other words, there is properly no history; only biography" (“history”). but if history is biography, then history is really the corrupted collective record of faux lives lived. standard legal disclaimer as used in novels. nineteen eighty-four: p. : “does the past exist concretely, in space? is there somewhere or other a place, a world of solid objects, where the past is still happening?'” (italics added.) see: res gestae -

); yet a hysterical wave of human memory recall is now being fostered in the united kingdom to send individuals to prison on the basis of memory recall . even when eye- witnesses to an event have reduced their observed experience to writing, they have subjected that redaction to orwell’s mantra that: “who controls the past controls the future: who controls the present controls the past” (nef ). while “a camera may not lie ”, its human operator can selectively record some images while not capturing others, and thus distort the representation of a past event perceived by viewers at a later time. almost as soon as it became possible to make copies of documents, enforced licensing by governing bodies formed the foundation for institutionalized censorship , and by content expurgation, overseers controlled all potential influence those documents might have on the public at large. sometimes complete works were removed from general circulation, but quite often redacted versions containing intentionally corrupted information were also put into wide circulation (see gilder and hagger - ). in many instances, with the passage of time, the propaganda value emitted by such corrupted texts has become the accepted version of particular events, because they have drowned out all pointers to the existence of alternative renditions. to make matters worse, the chief proponents of mass learning - mass-redaction and mass-propaganda - have often been religious organizations masquerading as the official voice of the source of all that exists, or will ever exist. they thereby impose nonsense by means of fear, in a similar manner to the scenario described in orwell’s ‘room ’ (nef ). primarily due to the efforts of mark williams-thomas, a student-lecturer at (uk) birmingham university, the name of deceased uk radio and tv personality jimmy saville has become a rallying call for ‘sex-crime’ investigations which have resulted in lurid headlines and prison sentences for a number of well-known individuals. these alleged offences stretch back into the s and they are all based upon memory-recall by alleged victims who appeared in court decades after the claimed events occurred. see: mark williams-thomas webpage http://www.bcu.ac.uk/social-sciences/criminology/employability/mark-williams-thomas and: jane mathews, “operation yewtree investigating new suspects including police officers and politicians” express online, october , – http://www.express.co.uk/news/uk/ /operation-yewtree- -new-suspects-police-officers-politicians (accessed november ). an interesting essay on this subject is available at: photographic fictions, “the camera does not lie”. the american museum of photography http://www.photographymuseum.com/phofictionsreading.html (accessed november ). historical overview of book censorship. http://viking.coe.uh.edu/~wmasterson/cuin /history.htm (accessed november ). mervyn hagger and eric gilder, “the british interregnum: a yesterday that never happened”. cultural and institutional memory as (a) means of progress (part i) hypercultura, vol , no / page the vanishing act three hundred years before orwell wrote his seminal work, an interlocking series of civil wars took place on the british isles archipelago. on the main island of great britain between the years and , a republican form of government was introduced, but its official memory was later expunged by employing the highly subjective and suggestive label of ‘interregnum’. this closed cultural laboratory by ‘time-branding’ has resulted in the implantation of an alternative, but bogus chronology, wherein the reign of one monarch has immediately followed another. both of them were named charles, and the second was the son of the first. however, the execution of the first king charles was followed by a unitary republic, and not by his son reigning as charles ii over his father’s two kingdoms . in , that intervening republic was terminated, and king charles ii began two new monarchies , since the original monarchies reigned over by his father had terminated with his execution in . during the creation period of those two new monarchies of king charles ii, his henchmen manufactured a faux timeline by making it illegal to refer to past events . when samuel pepys was a - year - old schoolboy, he was present at the execution of charles i. eleven years later pepys was desperate that his youthful desire to obliterate the king’s memory should itself be forgotten. fortunately, he had not only chance, but the law, on his side. forgetting was officially sanctioned: the act of indemnity and oblivion banned “any name or names, or other words of reproach tending to revive the memory of late differences or the occasions thereof” (norbrook ). while the official website of the british monarchy of today acknowledges that there was no seamless continuation connecting the reigns of charles i and charles ii, it does misleadingly call the intervening years an ‘interregnum’ . clearly, there is no scientific evidence to show that human beings have the ability to roll back time. in this instance, however, it is as if chapter one is followed by chapter three, while pretending that chapter two had never been written. therefore, according to this alternative scenario, chapter three is really chapter two. it is a truly proto-orwellian concept. it is also a current concept, because in it could be imagined that executives at google were performing as a presley tribute act , when they told european officials that “forgetting isn't easy” . separate kingdoms of england and scotland having a shared king. same as note although the implication is that the king is also the institution of the crown, this is obviously not the case. here the word ‘crown’ has two meanings: . a type of hat; . institutions managed by a variety of people sheltering under the name of a collective umbrella. while there is a little more transparency in their actions today, the record of individual administrators has been one of political infighting gaining enough power to unseat one king and install another to their liking. it is generally conceded that without the military masterminding of major-general george monck, the creation of the new monarchies established in the name of king charles ii could not have been accomplished, although: "centuries later, historians cannot agree on whether or not the restoration of the stuarts was monck's intention..." (don jordan and michael walsh, the king's revenge. london: abacus, . . - italics added) “forgetting was officially sanctioned: the act of indemnity and oblivion banned ‘any name or names, or other

removing information from public scrutiny is not a new one (gilder and hagger - ), but in this instance it served the purpose of obliterating legal precedent. this aspect of tampering with collective cultural memory is actually the result of a legal fiction derived from the ability to exercise nunc pro tunc in a most dishonest manner. by removing one document and substituting another, and then by pretending that the document substituted contains the same information as the document removed, sans inconsequential typographical-style errors, the past can be made to vanish within the twinkling of

another example is in the revival of a business corporation wherein the name of the original founding owner is substituted for a new owner who has bought the shell corporation as a result of a

into his father’s shoes at the very moment his father died. that product of nunc pro tunc laid the foundation for yet another work of legal fiction with the proclaimed union of , which merged the kingdom of england and the kingdom of scotland, into a joint kingdom of great britain. it was from that kingdom which many in scotland wanted to secede in as a result of a referendum. however, back in , just before scotland joined england in the creation of a united republic, the same king charles ii, who in became the separate king of england and king of scotland, had already been crowned in scotland as ‘king of great britain’ . the problem with that ceremony was and is that the kingdom of great britain did not come into existence until the year . that was when the bogus kingdom of england and the equally bogus kingdom of scotland, both of which were created in with charles ii as their shared but individual monarchs, formed the kingdom of great britain after the separate parliament at edinburgh was folded into a single parliament at westminster . in order to deal with this glitch in the thread of the historical timeline, many records falsely claim that the son of king charles i was actually crowned “king of scots", which of course, he was not . he was falsely crowned ‘king of great britain’. independence: from what? on july , , which was a mere years after the creation of the kingdom of great britain in , colonies united in a north american confederacy and it became known as the ‘united states of america’ (“primary documents in american history”). this confederacy of colonies issued their own unilateral divorce decree from the kingdom of great britain, and they called their act of disconnection a ‘declaration of independence’. those former british colonies replaced the institution of the british crown with an undefined ‘supreme creator’, although this source of their ultimate authority was further specified as being ‘nature’s god’, author of ‘nature’s laws’. as we shall see, it was by referring to this higher power that these confederated former colonies overcame the legal fiction that jefferson later drew attention to in his letter to major cartwright . while a supreme creator was immediately declared to be the ultimate source of all authority in the confederated united states of america, when the usa became a federal nation in , its founding laws were set forth in a written constitution which named ‘the people’ as its authors. however, ‘the people’ retained in their laws this same unspecified deity as their ultimate source for of all that exists. the institution known as the british crown is in law defined as a corporation sole (maitland - ) which, because it is an artificial creation, outlives its monarchical representatives who wave to citizen-subjects in much the same way that mickey and minnie mouse wave to disneyland tourists. it gives rise to the sloganeering chant that “the king is dead. long live the king! ”. it is this institution which holds the real power in today’s united kingdom of england, scotland and northern great britain is the largest island among thousands of islands which form the archipelago of the british isles, including the island of ireland. at that time, ‘great britain’ was limited to a geographical description of an island comprising most of the territory of two independent political sovereign nations called england and scotland. queen anne became the last monarch in line from charles ii, to rule separately over england and scotland, and the first queen of the kingdom of great britain. ireland would not be added to this mix for almost another hundred years in . several preceding monarchs beginning with james vi of scotland, who subsequently also became james i of england, tried to imply that their ‘union of crowns’ was their authority to claim title as ‘king of great britain’, but the validity of those claims was not accepted by either the ruling elite in england or scotland. the usa did not become a federal nation under its present constitution until june , with george washington as its first president who held that office from april , to march , . see note a cliché with both secular and religious claimed origins; in this instance it indicates continuity of office (crown), not current office holder (or current monarch representing the

ireland. it is to the british crown that the military swears its allegiance, and it is in its name that british courts administer their version of justice, and hold prisoners, and most importantly, it is by means of this institution that the wealth of the nation is controlled. during the recently failed referendum regarding the question of whether scotland should be an independent country , the hope of the ‘yes’ vote was to merely untangle the union of . voters on both sides remained silent about the bogus coronation of when some in scotland had crowned charles ii as “king of great britain”. they also remained silent on the subject of the republic which had united scotland with england. therefore, it was not surprising that both sides in the referendum debate remained silent about the true status of the currency presently in use by the united kingdom; yet both sides danced around this currency maypole while chanting questions about ownership of the currency. however, neither side really wanted to answer that question because it was a conundrum from which neither side had an escape plan. neither side wanted to tell the truth regarding the fraudulent way in which the governance of great britain has been conducted since ; nor the manner in which its bogus history has been promulgated to the masses. the reason for their silence is easy to explain: the crown is a subject that remains ‘off limits’ because it is founded upon a fraudulent series of events, and it is controlled by operatives who remain hidden within the shadows of privy council secrecy . the identity of the crown cannot be partially unraveled without taking events back to , and that is why the term ‘interregnum’ has always been used to prevent that from happening. jefferson’s personal links when jefferson wrote to cartwright on june , , his letter of was penned a mere years after jefferson had helped to write the ‘declaration of independence’ on behalf of the usa confederacy, and it was only years since the usa had been transformed into a federal nation. but in-between those two events, connecticut’s danbury baptist association had written to jefferson on october , and they were complaining that their state legislature did not believe that the first amendment to the u.s. constitution applied to their state. in reply to this baptist organization on january , , jefferson who was president at that time, wrote in part: “believing with you that religion is a matter which lies solely between man and his god the whole american people declared that their legislature would ‘make

the civil war battle sites of england with his friend and traveling companion, john adams. in , both men had been instrumental in creating the ‘declaration of independence’; but instead of visiting a nation where all previous ill-feeling about that document was forgotten and forgiven, a few years after their visit, british warships fired upon the usa during the war of , giving rise to events described in its national anthem ‘the star spangled banner’. it was also during that time that british troops invaded washington, dc and set fire to both the white house and the library of congress. the british waited to invade new orleans after that phase of hostilities had nominally come to an end . even before the creation of the confederated united states of america in , political and religious refugees had struggled to reach america’s shores. on board the mayflower, which had sailed years earlier in , there were passengers with neo-anabaptist beliefs .their tormentors included officials in control of the state church of england, which specifically named anabaptists as enemies . all of this was more than mere national history to jefferson, because it was specifically a part of his family history. in , which was years after the mayflower sailed for north america, king charles i was executed and the era of republic began in england. unfortunately, the departed king’s son decided to fight on until he was finally defeated at worcester. jefferson had reason to know the intimate details of the royalist defeat, because royalist reinforcements were cut-off before they reached worcester by an army led by colonel robert lilburne. he was a baptist fighting for issues with which jefferson identified . unfortunately there is no historical collection of baptist archives, as such. see: american baptist historical society. http://abcconn.org/history/index.php?title=american_baptist_historical_society (accessed november ). “the american baptist historical society (abhs)

this was a doctrine that jefferson agreed with, it also provided another reason why there was more than a genealogical bond between the lilburne and jefferson families. when thomas jefferson arrived as a tourist accompanied by his on-again, off-again, on-again friend john adams, both men were well aware of the lilburne name. it was no coincidence that the virginia house thomas jefferson was born in was called ‘shadwell’, because it had been named after a parish east of the city of london where his grandfather isham randolph on his maternal line, had married jane lilburne. but when the shadwell family home burned down, thomas’ father moved his family into a house name edge hill , and that is where thomas grew up. thomas jefferson’s mother was the daughter of jane lilburne, who came from a line stretching back to an uncle of robert and john. jane married twice, and as jane rogers, she married isham randolph. this couple produced jefferson’s mother, who gave birth to his sister named lucy. she married charles lilburne lewis, who gave one of her sons the first name of lilburne. thomas’ brother randolph also gave one of his children the first name of lilburne. john adams’ speech at worcester, england colonel robert lilburne was only one of several in the lilburne family who played important parts during the civil wars. after his army caused the final collapse of the royalist military cause at worcester, robert lilburne was sent to scotland to maintain martial law from a headquarters at dalkeith , and that is where he became acting commander of all military forces on land. it was because robert was in command, that he was able to throw open the doors to the founding of both baptist and quaker congregations in scotland. however, post-‘interregnum’ accounts of baptist congregations in scotland are a prime example of orwellian expurgation at work. in this instance its victims are ‘unable to remember real events’, because the history of the baptist church in scotland just vanishes from the scene once the republic is overthrown. the baptist union of scotland reports that many of robert lilburne’s men were “baptist soldiers who used their influence to establish small churches in leith, perth, cupar, ayr and aberdeen ”. when general george monck took over from lilburne about a year later, he turned back the hands of time by re-imposing religious

september , , with the essential assistance of robert lilburne’s troops. the former battlefield was not far from edgehill where the first battle in a series of civil wars had begun at, during . but it was in worcester that adams delivered a speech which he noted in his diary: at worcester that i was provoked and asked, “and do englishmen so soon forget the ground where liberty was fought for? tell your neighbors and your children that this is holy ground, much holier than that on which your churches stand. all england should come in pilgrimage to this hill, once a year". this animated them, and they seemed much edgehill and worcester were curious and interesting to us, as scaenes where freemen had fought for their rights. the people in the neighborhood, appeared so ignorant and careless pleased with it. perhaps their aukwardness [sic] before might arise from their uncertainty of our sentiments concerning the civil wars . adams asked in amazement: ‘and do englishmen so soon forget the ground where liberty was fought for?’ his answer would have to wait until it arrived in the form of a novel explanation hundreds of years later, during april . that is when it was penned by george orwell in that lonely farmhouse on the bleak scottish island of jura. orwell might well have re-written his answer as “they are unable to remember real events and they persuade themselves that they remember other events which never happened”. however, by it was not only a case of englishmen at worcester forgetting about “the ground where liberty was fought for”, or scots who forgot to ask the real question about their union with england during their failed referendum of . americans have seemingly joined the ranks of the forgetful and adopted the attitude that jefferson and adams must have dreamed-up, a concept of individual rights when they wrote the ‘declaration of independence’. although jefferson did not acknowledge his real sources of inspiration, a united states supreme court justice undertook that task for him, albeit about years after jefferson’s death (gilder and hagger “the pedigree” - ). the supreme court remembers while robert was a baptist, his brother john had drifted from puritan to quaker (feuer ) by the time he died. ‘freeborn john’ was more-or-less led by the circumstances in which he found himself, and this is how he developed his skills as both a writer and orator. his fiery legal career began with a landmark trial , in , when he established his right to remain silent, and he made it clear that he would be a slave to none. that star chamber

the answer is nothing, nothing at all, because john was not the king of scotland . but this will not deter the many engaged in obfuscation as a means of selling a fantasy version of history to tourists as ‘british’ history. while critics may laugh at the idea of an australian reenacting the life of william wallace and events that never happened, while at the same time ignoring many events that did happen during the actual life of this man, the movie braveheart has been taken to heart by the promoters of scottish tourism as a useful tool to rid visitors of their ‘spare change’. therefore, we should also remember that orwell wrote his tale about a dictionary while huddling from the cold on that bleak scottish isle. unlike the title of his novel, the publication date of that dictionary is still in the future, because the work of ridding our collective lives-lived of reality by means of obfuscation through redaction is still a work in progress. best of all for the scriptwriters, it is also a process that seems to be both entertaining and one that makes money. perhaps one day we will all come to love ‘big brother’. there is still time, because is still well into the future, our future, the future of us all . “his conflict with the church led to his excommunication. the annulment of magna carta by pope innocent iii in august , at john’s request, led to a renewal of the baronial revolt which was still raging when john died in october ”. magna carta: people and society. magna carta. british library. http://www.bl.uk/magna-carta/articles/magna-carta-people-and-society (accessed november ). after king james vi of scotland who was king james i of england, references were made to the king ruling over territory, and not people. “critics consensus: distractingly violent and historically dodgy”. braveheart ( ). http://www.rottentomatoes.com/m/ -braveheart (accessed november ). “…the struggle was finished. ….he loved big brother”. the concluding words in orwell’s novel nineteen eighty-four: p. . mervyn hagger and eric gilder, “the british interregnum: a yesterday that never happened”. cultural and institutional memory as (a) means of progress (part i) hypercultura, vol , no / page works cited “adams family papers”. massachusetts historical society. web. nov. . “adamson v. california, u.s.

found that bax insertion into the mom was the earliest apoptotic step inhibited by bcl overexpression. paradoxically, we also found that bax translocation to the mitochondria was not inhibited but rather spontaneously increased in this same genetic context. this increase in mitochondrial associated bax required a physical interaction be- tween bax and bcl . we therefore propose that, at least when upregulated, bcl behaves as a ‘decoy receptor’ which sequestrates bax at the mitochondria but inhibits its insertion into the mom, committing the cell to survive. supported by nyu research

university of central florida, orlando, fl, usa. cancer is defined by a pronounced inhibition of cell death. the bcl family of proteins tightly regulates the delicate balance between life and death. one method of regulation is the compartmentalization of antagonistic members. for example, bax, a pro-apoptotic member of this family, acts as the penulti- mate factor in the apoptotic cascade by releasing apoptogenic factors such as cytochrome c from the mitochondrial lumen. the normally cytosolic protein translocates from one internal compartment to another through an elusive mechanism. individual organelles are defined not only by function (mediated by specific membrane bound proteins), but by the unique composition of their phospholipid membranes. in this work, we have evaluated the contribution of organelle lipids to the localization of of bcl proteins. -pos in search of the structure of mac in the mitochondrial outer membrane pablo m. peixoto , christian renken , shefali

groups have tried to determine the structure of the channel (mac) formed in mitochondrial outer membranes (om) of apoptotic cells or in syn- thetic membranes by bax and related proteins/peptides, using electron micros- copy (em), atomic force microscopy and x-ray diffraction. here, pore-like structures ~ - nm were handpicked from transmission em images of ura- nyl-acetate-stained oms isolated from control and apoptotic (il -deprived) fl . cells. these ‘‘candidate pores’’ were aligned by correlation procedures, and class averages defined by principal component and k-means analyses. main differences in the class averages were ( ) the presence of one or more dark (stain-filled) pores, and ( ) the nature of white (stain excluding) features around the pores. a class average consisting of a single -nm pore with pro- nounced white rim was rotationally averaged and used as a reference for cross-correlation searches of om images from control and apoptotic cells. searches using this -nm ‘‘donut’’ motif and the same motif doubled in size ( -nm ‘‘donut’’) yielded thousands of ‘‘hits’’ in both control and apoptotic membranes, which were subsequently aligned and classified as before. the pre- dominant stain-filled structures found with both motifs were not circular but elongated (up to ~ x nm), extending away from stain-excluding crescent- shaped features. the radial anisotropy ruled out reference bias and was in- consistent with pores formed by rings of evenly spaced protein subunits. we hypothesize that the different classes of structures detected represent stages in formation of mac as an increasingly large membrane bilayer defect (or ‘‘cleft’’) induced by successive aggregation or clustering of bax/bak molecules. a progressive assembly mechanism for mac has been recently suggested by real-time monitoring of mac conductances in isolated mitochondria by patch clamping (martinez-caballero et al. j biol chem : - ). supported by nih grant gm . -pos effects of mac formation on mitochondrial morphology pablo m. peixoto, shin-young ryu, robert range, kathleen w. kinnally. new york university college of dentistry, new york, ny, usa. accumulating literature associate mitochondrial dynamics with apoptosis, since regulation of either process has reciprocal effects. these processes seem to converge in formation of the mitochondrial apoptosis induced channel, mac, which releases cytochrome c and triggers the degradation phase of apo- ptosis. while bax and bak, core components of mac, were shown to interact with fusion and fission proteins, some studies also suggest proteins from the in- termembrane space could leak to the cytosol and further promote mitochondrial fission during apoptosis. the temporal relationship between apoptosis induc- tion, mac formation and mitochondrial fragmentation was investigated by time lapse microscopy. mac function was induced through staurosporine treat- ment and microinjection of tbid or cytochrome c. mac formation and mito- chondrial dynamics under these conditions were monitored in hela cells (clone ) that stably express low levels of gfp-bax and were transiently transfected with a pdsred- plasmid. gfp-bax relocation to mitochondria only during apoptosis signals mac formation, while pdsred- expression shows mito- chondrial structure as red fluorescence. treatment with staurosporine and microinjection with tbid or cytochrome c induced relocation of bax and col- lapse of the mitochondrial network. the temporal relationship between these two events was further analyzed. interestingly, pretreatment with imac , a spe- cific mac blocker, protected against cell death and prevented mitochondrial fragmentation after tbid injection. our results suggest a link exists between mac formation and collapse of the mitochondrial network during apoptosis. supported by nih grant gm . -pos mechanism of the mitochondrial cytochrome c release wave in bid-induced apoptosis soumya sinha roy, cecilia garcia-perez, erika davies, xuena lin, györgy hajnóczky. thomas jefferson university, philadelphia, pa, usa. bid, a bh -only bcl family protein, plays a central role in apoptosis. bid is cleaved by caspase- and other enzymes forming tbid that induce mitochon- drial outer membrane (omm) permeabilization and cytochrome c (cyto-c) re- lease. however a mystery remains how bid synchronizes the function of a large number of discrete organelles, particularly in mitochondria-rich liver or muscle cells. here we showed that tbid ( . - nm) elicited progressive omm perme- abilization and complete cyto-c release with a dose-dependent lag time and rate in h c cell populations. once started, the omm permeabilization was not pre- vented by tbid washout. in contrast, the dose-response for digitonin-induced omm permeabilization displayed quantal behavior. in single cell imaging studies, permeabilized h c and primary human cardiac cells transfected with cyto-c-gfp showed complete tbid-induced cyto-c-gfp release closely followed by mitochondrial depolarization. the cyto-c-gfp release started at discrete sites and propagated through the mitochondria with a constant velocity and a relatively stable kinetic of release in each organelle. similar tbid-induced cyto-c-gfp release wave was documented in intact h c cells transfected with tbid. the waves were not dependent on ca þ , caspase activation or permeabil- ity transition pore opening. however, treatment with mntmpyp, a ros scav- enger or overexpression of mitochondrial superoxide dismutase suppressed the coordinated cyto-c release and also inhibited tbid-induced cell death. on the other hand, both superoxide and hydrogen peroxide sensitized mitochondria to the tbid-induced permeabilization. thus, tbid engages a ros-dependent inter-mitochondrial signaling mechanism for spatial amplification of the apoptotic signal by mitochondrial waves. -pos role of milton domains in the calcium-dependent regulation of mito- chondrial motility sudipto das, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. the mammalian grif and oip , and the drosophila milton are kinesin- binding proteins that form a complex with the miro gtpase, an outer mitochon- drial membrane ef-hand protein, to support the movement of mitochondria along the microtubules. our study demonstrates that in h c cells overexpress- ing oip or grif , the basal motility of mitochondria is increased, whereas the sensitivity to calcium-induced movement inhibition is decreased. to dissect the interaction between milton, kinesin and miro, three different milton constructs were tested: milton ( - ), the soluble domain of milton; milton ( - ), lacking the kinesin heavy chain binding site and milton ( - ) that lacks additional ~ amino acid presumably containing part of the miro binding site. immunohistochemistry revealed that the overexpressed milton ( - ) was cytoplasmic, whereas the other two milton constructs showed mitochondrial localization. the basal mitochondrial motility was in- creased by milton ( - ) but was not altered by milton ( - ) or mil- ton ( - ). a plot of mitochondrial motility against slowly rising cytoplasmic [ca þ] induced by thapsigargin ( mm), shows that overexpression of milton ( - ) significantly reduced the calcium sensitivity of mitochondrial motil- ity reminiscent of oip and grif . by contrast, milton ( - ) or milton ( - ) did not have any effect. the thapsigargin-induced cytoplasmic calcium signal was not affected by any of the milton constructs. these data indicate that monday, february , a the c terminus of milton is an important regulator of the mitochondria associated motors and is involved in conferring the calcium sensitivity from miro to the motors. milton - is sufficient for the mitochondrial binding, whereas the - amino acids are critical for the control of calcium sensitivity of mi- tochondrial motility. -pos biophysical properties of mitochondria undergoing fusion xingguo liu , orian shirihai , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, boston university, boston, ma, usa. emerging evidence shows the importance of genes controlling mitochondrial fusion in physiology and their deregulation in neurodegenerative and metabolic disorders. however, apart from djm, the biophysical properties of the fusion- competent mitochondria remain elusive. to evaluate the conditions of contact formation and fusion, we used organelle-targeted fluorescent proteins, includ- ing photoactivatable gfp, which allow tracking of individual mitochondria. in h c cells, almost every mitochondrion is aligned with microtubules that pro- vide the primary tracks for mitochondrial movement. our results show that ~ % of fusion events involve moving mitochondria. however, fusion occurs irrespective of mitochondrial speed. furthermore, ~ % of fusion events in- volve the tip portion of the mitochondrion, whereas only ~ % of these events involve organelle side. nocodazol, a microtubule disrupting agent that inhibits mitochondrial movements decreases the fusion frequency and changes mito- chondrial fusion sites. strikingly, - % of the physical contacts between ad- jacent mitochondria did not result in fusion events. to evaluate whether the fu- sion efficacy depends on the spacing between the outer and inner mitochondrial membranes we used drugs that alter the matrix volume. valinomycin, a k þ ion- ophore that induces matrix swelling evoked a decrease in mitochondrial motil- ity leading to fewer contacts among mitochondria but the number of fusion events was maintained, indicating an increase in fusion efficacy. this change occurred at a low valinomycin concentration ( . nm) that did not affect djm or opa cleavage. nigericin ( . mm), a k þ /h þ ionophore that induces shrinkage of the matrix elicited fusion inhibition and mitochondrial aggrega- tion. importantly, no motility inhibition or opa cleavage occurred at the same time and the djm was increased. these results suggest that mitochon- drial fusion is facilitated by mitochondrial motility, the key determinant of the inter-mitochondrial encounter numbers and preferentially involves the front-tip of the moving organelle. in addition, fusion efficacy depends on the mitochondrial matrix volume. -pos mitochondrial fusion dynamics in human skeletal muscle-derived cells veronica eisner, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. mitochondria have a fundamental role in both muscle physiology and pathol- ogy. mitochondrial fusion and fission are important for energy metabolism, calcium homeostasis and cell death. however, the mechanisms underlying mitochondrial dynamics are poorly understood, especially in physiological models such as skeletal muscle. here we evaluated mitochondrial fusion dy- namics in human skeletal muscle cells (husmc). skeletal muscle satellite cells were isolated from human muscle biopsies and were maintained and dif- ferentiated in cell culture. mitochondrial fusion events were evaluated by con- focal imaging of cells expressing mitochondria matrix targeted dsred and matrix targeted or outer mitochondrial membrane (omm) targeted photoacti- vatable-gfp. when we tagged the mitochondria in ~ % of total cellular area with photoactivated-gfp, we found those mitochondria undergoing matrix fusion with a frequency of . . events/min/cell (n= ). among the fusion events, % led to complete fusion and only % was followed by separation at the apparent fusion site within to seconds. both complete and transient fusion events resulted mostly from longitudinal mergers, involving end to end interaction or from mergers of adjacent mitochondria in side to side orien- tation. furthermore, we found that omm and matrix fusion are sequential and separable steps, displaying . seconds gap (n= ). finally, we evaluated the mitochondrial fusion dynamics in husmc derived from both normal and malignant hyperthermia susceptible individuals. at resting state, no significant differences were found in the number of events or in their characteristics. thus, mitochondrial fusion commonly occurs in husmc, and enables mixing of both soluble and integral membrane factors. this process would help to maintain the stability of mitochondrial metabolism. the relatively low frequency of the tran- sient fusion is probably due to the parallel organization of the cytoskeletal tracks for mitochondria and to the limited mitochondrial motility. -pos imaging interorganelle contacts and local calcium dynamics at the er-mitochondrial interface györgy csordás , péter várnai , tünde golenár , swati roy , george purkins , tamás balla , györgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary, national institutes of child health and human development, bethesda, md, usa. the local coupling between er and mitochondria is essential for proper cell function. a main role of the er-mitochondrial junctions is to provide a local calcium signaling domain that is important both for keeping energy production in line with demand and for the control of apoptotic mechanisms. so far it has not been possible to visualize the tiny er-mitochondrial contact points in living cells or to monitor the localized [ca þ] changes in the narrow space between er and mitochondria ([ca þ]er-mt). here, we exploited rapamycin-mediated heterodimerization of fkbp and frb domains of fluorescent protein constructs respectively targeted to the outer mitochondrial membrane and the er as drug-inducible inter-organelle linkers to identify er-mitochondrial contacts and to measure the [ca þ ]er-mt. high- resolution fluorescence imaging and d reconstruction revealed rapamycin-in- duced clustering of the er-targeted fluorescent linker-half to the contact areas with the mitochondria without major changes in the spatial arrangement of the er. essentially all mitochondria displayed contacts with the er in both rbl- h and h c cells. plasma membrane-mitochondrial contacts were less frequent with er stacks being inserted between the two organelles. single mitochondria display discrete patches of er contacts as well as continuous as- sociations. cytoplasmic and mitochondrial matrix [ca þ] showed robust er-mitochondrial ca þ transfer with considerable heterogeneity even among adjacent mitochondria. pericam-containing linkers revealed ip -induced [ca þ ]er-mt signals that were resistant to buffering bulk cytosolic [ca þ ]c in- creases and exceeded um. the largest [ca þ ]er-mt signals did not occur at the tightest associations, indicating space requirements for the ca þ transfer machinery and functional diversity among er-mitochondrial junctions. these studies provide direct evidence for the existence of high ca þ microdo- mains between the er and mitochondria in living cells, and open new possibil- ities to probe the functional importance of this specialized compartment. -pos dependence of er-mitochondria calcium transfer on different ip receptor isoforms tunde golenar , szava bansaghi , gyorgy csordas , david i. yule , suresh k. joseph , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, university of rochester medical center, rochester, ny, usa. ip receptors (ip rs) release ca þ from the er, which is locally relayed to the mitochondria to control several aspects of mitochondrial function. recent stud- ies have suggested that type ip rs (ip r ) are particularly important for me- diating the ca þ transfer at the er-mitochondrial interface. we set out to sys- tematically evaluate the respective role of each ip r isoform in chicken dt cell lines that express only one ip r isoform (double-knockout, dko , dko and dko ) or provide a null-background (triple-knockout, tko) for analysis of mammalian ip rs and their mutants. simultaneous imaging of cytoplasmic and mitochondrial matrix [ca þ] ([ca þ]c and [ca þ]m) was performed in either permeabilized cells chal- lenged with ip or in muscarinic receptor overexpressing intact cells stimulated with carbachol (cch), an ip -linked agonist. saturating ip evoked complete discharge of er calcium and resulted in comparable [ca þ]m increases in each dko. furthermore, the cch-induced [ca þ]c spike was closely followed by a [ca þ]m rise in each dko. when tko cells were rescued with rat ip r or ip r , the latter mediated a larger [ca þ]c transient but the [ca þ]m increases were very similar for both isoforms. the relationship between the [ca þ]c peak and the corresponding [ca þ]m response was also very similar for ip r and ip r . to assess the impact of the release kinetic through ip r in the mitochondrial ca þ transfer we used two point mutants of the ip r , which display either enhanced inhibition by ca þ (d n) or are relatively insensitive to ca þ inhibition (d n). d n showed dampened [ca þ]m signal and [ca þ]m vs. [ca þ]c relationship, whereas d n displayed a steeper [ca þ]m vs. [ca þ]c relationship than the wild type ip r . thus, each ip r isoform can support local er-mitochondrial ca þ transfer and their competence to activate mitochondrial ca þ uptake depends on their deactiva- tion kinetic. compartmentalization of bcl family proteins mediated by organelle

ourselves within a place: monticello by thomas jefferson and taliesin by frank lloyd wright this article consists of a comparative description of two buildings: monticello, thomas jefferson’s residence which he built for himself in virginia, and taliesin, the studio and home of frank lloyd wright in wisconsin. first, the text studies the architectural references and evolution of the project for monticello, in order to later focus on the taliesin´s explanation. there is a certain similarity in the way that monticello and wright’s houses (especially the ward willits house) extend horizontally across the land. the thesis of this article is that both jefferson’s and wright’s residences rest upon a hill, but monticello crowns the top while taliesin borders it, like an eyebrow. in conclusion, we can say that taliesin is a “natural house”, which manages to fully integrate its architecture with nature. palabras clave palabras clave: casa, proyecto, evolución, corona, natural

stern narra, entre otras muchas historias de la arquitectura norteamericana, la de dos edificios, monticello —la casa que thomas je- fferson construyó para sí mismo en virginia— y ta- liesin —la casa y estudio de frank lloyd wright en wisconsin—. jefferson eligió como emplazamiento la cima de una colina próxima a la plantación de su padre y lugar de su nacimiento, al otro lado del río rivanna, y dirigió su edificio hacia el oeste, mi- rando hacia el territorio indio que se extendía más allá de los pies de la colina. la decisión de cons- truir encima de una colina, a pesar de los numero- sos problemas prácticos que esto suponía, incluida la escasez de agua, reflejaba las altas miras de je- fferson al planear su casa, su fe en las casi ilimita- das posibilidades inherentes a la vasta expansión continental. la posición dominante de la casa per- mitía una vista sobre el paisaje lejano, un paisaje que para jefferson “era un jardín continental sin paralelo en su belleza y como tierra de promisión”. n desde el punto de vista práctico, su interven- ción en la colina consistía en su aterrazamiento y la subsiguiente plantación de jardines y huertas, que contrastaban con el bosque circundante y que su- pusieron la creación de un verdadero asentamien- to para él, su familia y todo el personal a su servi- cio. monticello era el centro de una plantación de hectáreas, en gran medida autosuficiente y que incluía cuatro granjas. la casa estaba rodeada por huertas y distintos tipos de jardines, en con- creto jardines de flores, de verduras y de frutales, de modo que los terrenos alrededor del edificio se convirtieron en una especie de laboratorio vivo dos modos de situarse en el lugar j.a.cortés f monticello. vista aérea desde el oeste (william howard adams.

la creación de monti- cello fueron la elección del lugar exacto de implanta- ción de la casa y la orientación de la misma. un plano de jefferson de toda la propiedad dibujado en muestra la localización de los terrenos en relación con el río rivanna y la carretera larga y serpenteante que conduce a la casa desde el este. es especialmen- te significativo que, dada la escala del plano, no se dibuja la planta de la casa, pero sí se marcan los dos ejes de la misma. en otro plano, de y a escala mayor, se dibuja esa planta y el nivel horizontal de forma oval y plantado de césped en el que la casa se asienta. se dibuja también el paseo recto al sur de la casa —en el que se localizaban los distintos talleres con que contaba la propiedad— y los cuatro caminos de circunvalación que rodean la colina de monticello a distintos niveles, estableciendo un orden concéntri- co alrededor de la casa. en otro plano dibujado por jefferson a partir de , éste señala las distintas es- pecies vegetales que proyecta plantar alrededor de la casa, lo cual muestra la importancia que para él tenía esta cuestión.n pocas casas en los estados unidos de américa refle- jan más claramente la personalidad de su dueño que el monticello de jefferson. su proyecto, construcción y remodelación se extendieron a lo largo de más de cuarenta años. jefferson empezó a edificar monti- cello en —cuando tenía veinticuatro años de edad— y, como la construcción avanzó lentamente, la primera casa estaba aún sin terminar cuando en partió para francia en misión diplomática. des- pués de su regreso de europa en y de sus cuatro años como ministro de estado, jefferson comenzó a rediseñar monticello agrandando la casa por el pro- cedimiento de duplicar casi simétricamente las anti- guas habitaciones respecto a un nuevo eje formado por pasillo, escaleras y recintos de servicio. cuando, al final de su segundo mandato como presidente, je- fferson se retiró de la vida pública en , la casa estaba prácticamente acabada y amueblada. como sigue señalando stern, el nombre italiano que jefferson eligió para su casa y plantación —monti- cello— y también en cierta medida su localización constituían un homenaje a palladio, el cual señalaba como segundo emplazamiento recomendable para una casa un lugar “elevado y alegre”.n jefferson, que había estudiado atentamente los cuatro libros de ar- quitectura, había constatado con consternación la divergencia entre los modelos originales y no sólo las copias coloniales, sino también los más importantes ejemplos ingleses. este deseo de vuelta a una arqui- tectura más fielmente palladiana mostraba el desa- grado de jefferson con la arquitectura colonial típica de las plantaciones de virginia, una arquitectura que seguía los modelos georgianos. durante su estancia en francia, jefferson pudo co- nocer de primera mano algunos ejemplos de arqui- tectura romana, inspiradora en gran medida de la del propio palladio. a su vuelta, decidió reconstruir monticello como un símbolo de la nación americana. surgió así un edificio en forma de templo clásico, con un pórtico con frontón en cada fachada y una cúpula algo incongruente rematando el conjunto. dos largas alas en l, casi enterradas en la ladera, se proyectan desde la casa y abrazan un espacio en u. con sus cu- biertas planas, forman pasarelas que conducen a los cuerpos extremos, los cuales se perciben como pa- bellones aislados en medio de una gran extensión de césped.n en varias de sus obras, vincent scully señala, con su poética manera de expresarse, la singularidad y el significado de algún modo heroico de la relación entre monticello y su emplazamiento: “su colina, monticello, es un montículo perfecto, como un to- los regio, hinchado en su perfil y lo suficientemente pequeño para que la compacta casa pueda ahuecar debidamente su cima y completar la forma de la co- lina mediante su cúpula. colinas más altas se elevan como olas a su alrededor, y la cadena de montañas blue ridge se levanta hacia el oeste con el vasto de- safío de la frontera”.n sin embargo, el mismo scully dos modos de situarse en el lugar j.a.cortés n el emplazamiento recomen- dado en primer lugar era la orilla de un río. n véase stern, op. cit., p. . n vincent scully. american architecture and urbanism, cit., p. . f planta de robert morris y primeras plantas de

villa rotonda de palladio, majestuosa en su asentamiento sobre la colina. pero en monticello puede también detectarse una tensión entre la retó- rica clásica y las tradiciones vernáculas, de modo que el edificio expresa el intento de expandir las fronte- ras existentes, extendiéndose lateralmente, lo que se convertiría posteriormente en algo característica- mente americano.n a pesar de la clara influencia de palladio en este edificio de jefferson, hay que tener en cuenta que las formas palladianas se habían fil- trado a inglaterra y a américa a través de la visión pintoresca del paisajismo inglés, por lo que sus deri- vados tenían menos consistencia arquitectónica que los originales del maestro del véneto. además de la influencia general de palladio, scully se- ñala como fuente específica para los proyectos origi- narios de monticello una planta tomada del libro del inglés robert morris selected architecture, en la que el bloque central de la planta se proyecta ligeramente hacia delante y hacia atrás respecto a los dos laterales. en sus primeras plantas, jefferson hace más gruesa la masa de las chimeneas y adelgaza en cambio las pa- redes, de acuerdo con lo que eran las casas coloniales típicas. al mismo tiempo, cambia las proporciones de los bloques laterales, de modo que tanto ellos como el central se proyectan según los dos ejes. de hecho, el prisma que aún constituía el proyecto de morris des- aparece; en su lugar, empieza a definirse un esquema cruciforme. a continuación, jefferson clarifica este esquema de dos ejes que se cruzan al dar continui- dad transversalmente al espacio interior y al extender el eje de acceso hacia afuera mediante la adición de lo que parece que hubiera sido una loggia con arcos. pero no se detiene ahí; extiende más los dos ejes, si- tuando habitaciones poligonales en tres de los lados y prolongando los dos extremos del eje de entrada mediante porches con columnas. además, de acuerdo con las villas palladianas, el eje de entrada ha quedado libre como eje visual y de recorrido que atraviesa la casa, para lo que las chimeneas se sitúan sólo en las paredes laterales del bloque central. cpa .indd / / : el lugar (ii) cpa_ p lograda la extensión según los dos ejes horizontales, jefferson desea también darle a la casa un eje vertical —al menos exteriormente— que lo fije a su empla- zamiento. para ello recurre al tambor y la cúpula así como al frontón del pórtico —que engloba dos plantas en la apariencia de una—, tomados todos ellos de la tradición que procede de la villa rotonda de palladio y pasa por la villa chiswick de lord burlington. pero, a diferencia de la rotonda, e incluso de chiswick, la cúpula de monticello no funciona interiormente como culminación de la sala que está debajo; en su interior sólo hay una habitación de ático. no existe un espa- cio vertical que se contraponga a los ejes horizontales, que son los que caracterizan la organización de la villa; un potente eje conduce al interior de la casa desde la pendiente de la colina y de nuevo al exterior de la cima allanada.n las alas típicas de la tradición de las villas palladianas —no de la rotonda— “son apartadas del uso que esa tradición hace de ellas como un elemento humanista que abraza al que va a entrar y son empu- jadas bajo tierra para abrazar, en cambio, a la propia colina bajo su cima”.n según scully, la planta de monticello prefigura la de la casa ward willitts de frank lloyd wright. la liber- tad respecto a las restricciones antiguas es el tema común de ambos arquitectos, los dos se fijaron el mismo problema: cómo hacer estallar la caja. si en aquélla los ejes tratan de romper la caja compacta y extenderse libremente, en ésta lo llevan a cabo final- mente. si en el edificio de jefferson el volumen del edificio está encerrado en un tenso combate entre la vertical autocontenida y la horizontal expansiva, con la cúpula y las alas pugnando fieramente, en el de wright todo cede ante la extensión horizontal de los planos de cubierta. además, la casa retoma un com- ponente abandonado por jefferson en el desarrollo del proyecto de monticello: la chimenea colonial situada en el centro de la planta y desde la que se proyectan los ejes en cruz.n dos modos de situarse en el lugar j.a.cortés n véase ibídem, pp. - . n neil levine. the architec- ture of frank lloyd wright. nueva york, .

pasado y, en concreto, respecto a la caja cerrada del edificio tradicional —y de ahí la expan- sión horizontal—, el otro tema que ya se plantea en monticello es el del control de la naturaleza, el de la posesión de la tierra por el hombre: “la casa coro- na la colina cónica, la controla, como la tumba de un héroe”.n esta casa para una sola familia encarna el instinto de posesión de una extensión de terre- no, de dominio sobre el mismo. y es precisamente esta relación de la casa con la naturaleza en general y, en concreto, con el terreno en el que se asienta la que diferencia monticello de otra casa, el taliesin de wright. “a diferencia de la de jefferson, la casa de wright trata de abrazarse a la colina en vez de coro- narla; éste construyó para sí mismo no un panteón sino una cueva y una tienda en su seno”.n robert stern desarrolla esta idea sobre taliesin en su libro antes mencionado y lo pone también en para- lelo con monticello: “la obra de frank lloyd wright en la casa-estudio a la que llamó taliesin, en spring green, wisconsin, trató de rivalizar con el monticello de jefferson como autobiografía y como modelo para el destino arquitectónico y cultural de américa.”n después de haber abandonado en oak park — un suburbio de chicago en el que había vivido duran- te más de veinte años n — y de pasar un año en europa—, wright volvió en el otoño de para establecerse a finales del año siguiente en el campo de wisconsin donde había crecido y empezar allí una nueva vida. pero la valoración que wright hacía de la situación era menos optimista que la de jefferson: “desanimado por mucho de lo que vio en el mundo industrializado, se retiró a la naturaleza. anidó su casa en la colina y le dio el nombre —topográficamente explícito— de taliesin, que significa ‘borde resplan- deciente’ en galés. taliesin era también el nombre de un legendario poeta galés del siglo quinto, una identificación que expresaba la tendencia anticlási- ca de wright.” n a pesar de las coincidencias con monticello, en el sentido de una vuelta a la tierra, la relación con ésta es distinta en ambos casos. para je- fferson, el diálogo entre el hombre y la naturaleza era mutuamente edificante, mientras que para wright la naturaleza ocupaba el primer lugar. n por ello, taliesin fue construida con fachadas de pie- dra local cortada toscamente, cubiertas bajas y una horizontalidad insistente que hace que el edificio parezca parte del paisaje. “taliesin era una obra de integración ambiental, que deliberadamente borra- ba la separación entre lo hecho por el hombre y lo natural”.n como señala stern, cada elemento del diseño de wright corresponde al paisaje circundan- te. la piedra amarilla a las colinas locales; el acabado de la madera a los troncos grises de los árboles; las paredes revocadas a los bancos de arena del río. así, taliesin fue el primer edificio americano que estaba completamente en paz con el continente. sin em- bargo, las fuentes en las que se inspiró no eran sola- mente americanas. mantuvo la gran chimenea como corazón sólido de la casa y con su sentido primario de protección según la tradición doméstica colonial. pero el sentido de vinculación con la tierra, los teja- dos bajos que se proyectan hacia el suelo y el patio suavemente perfilado y puntuado por estatuas sugie- ren las villas campesinas italianas que wright conocía dos modos de

(divisando) las copas de los árboles.” n como dice levine, antes incluso de ser una casa, taliesin era una colina. una vez decidido a construir en esa colina, wright tomó otra decisión fundamental, referente a su modo de asentarse, una decisión que da la clave para entender el significado de taliesin y subraya otros de sus aspectos. para aprovechar la vista panorámica sin comprometer la integridad de la colina, wright no construyó sobre su cima, sino que rodeó con las alas de la casa sus dos flancos prominentes, pero clara- dos modos de situarse en el lugar j.a.cortés f spring green

ésta no le da la espalda, sino que establece una estrecha conexión con ella por medio del patio. aunque desde puntos algo distintos, tanto en el proyecto de abril como en el definitivo de junio la entrada a la casa se realiza desde atrás, a tra- vés del patio, dándole así una condición de espacio delantero: “no hay patio trasero. taliesin es todo él patio delantero”. n en efecto, como observa levi- ne, wright volvió del revés el modelo de la ‘casa de la pradera’. en vez de rodear a un elemento interior, como el núcleo de la chimenea típico de ésta, talie- sin se organiza alrededor de un elemento exterior del paisaje natural. el patio se convirtió en el núcleo de un diseño global en el que wright comenzó a liberar- se de la dependencia respecto a los patrones clásicos de simetría y axialidad que aún habían sido tan bási- cos en su obra anterior y que conferían a la casa de la pradera una cierta formalidad. tanto la planta como el uso de los materiales enfatizan la informalidad del edificio, su irregularidad y su íntima relación con el entorno natural, ya que “debía ser de la colina, per- tenecer a ella... como los árboles y las rocas”, a la vez que “era impensable, intolerable, que cualquier casa fuera puesta encima de aquella amada colina”. n se podría decir que el patio extiende su dominio a través de la casa y se asoma al paisaje desde la loggia y las terrazas. n desde la entrada al patio por la por- te-cochère, la vista está ya canalizada hacia la aper- tura al río, enmarcada por la loggia. pero el patio es también un espacio encerrado en sí mismo y con un tratamiento paisajístico propio, aunque relacionado con otras plantaciones que se extienden más allá de la casa. el jardín incluido en el patio es un jardín for- mal, al que wright denominaba un “jardín de flores” y que estaba diseñado según el modelo de giardino segreto propio de las villas italianas del renacimien- to. en la ladera sur de la colina, a lo largo del camino de acceso, creó a un lado un “jardín aterrazado” que prolongaba el “jardín de flores” más allá de la porte- cochère, y al otro lado un jardín de verduras. delante f taliesin. plano de la propiedad, finales de la

viñedos y huertas. muy importante paisajísticamente y desde el punto de vista práctico del riego era la manipula- ción que hizo wright del elemento del agua. represó un arroyo que corría a los pies de la colina para crear un “jardín de agua”, “un estanque al pie de la colina que elevaba el nivel del agua en el valle hasta que pudiera verse desde taliesin”.n como sigue señalando levine, la implantación en la colina, el aterrazamiento, el jardín de flores ence- rrado, la torre-belvedere en el otro extremo de la u (respecto a la porte-cochère), el asiento de piedra y la exedra en la cima de la colina, la estatua y, espe- cialmente, las fuentes, estanques y el uso controla- do del agua son todos reminiscentes de ejemplos de villas italianas que wright conocía por publica- ciones o directamente durante su reciente estancia en fiesole. n entre villa y casa de labranza, parece en cualquier caso innegable la influencia de la cam- piña de la toscana o del lacio en taliesin. wright describió taliesin como la primera “casa na- tural”, n ya que consideraba que en su arquitectu- ra había alcanzado un equivalente de la naturaleza. en este sentido, deseaba que la casa pareciese lite- ralmente parte de la colina: “la relación con la na- turaleza no era ya una de analogía, mediada por las convenciones históricamente determinadas del tipo, sino una de homología”. n frente a la idea de una casa que se añade a un paisaje, taliesin era una par- te integral de ese paisaje, de modo que la naturaleza —la colina— venía primero y la casa después, no al revés. la casa no era algo con identidad propia aun- que cualificado por la naturaleza, sino que ésta era modificada para convertirse en una casa. n en efec- to, a diferencia de la típica ‘casa de la pradera’ —que afirmaba sus propios límites y bordes para condensar la imagen del paisaje en sí misma—, en taliesin se bo- rró deliberadamente la línea divisoria entre edificio y paisaje de modo que “no fuese fácil decir dónde aca- baban los pavimentos y paredes y dónde comenzaba la tierra”.n aunque esto es así y, además, las vistas desde le patio y desde la casa se extienden más allá de los confines de la misma y relacionan el interior y el exterior como si se tratase de un único espacio continuo, n lo cierto es que, junto a esta condi- ción extrovertida, taliesin tenía que cumplir tam- bién una condición introvertida. tenía que ser un refugio, tanto en los sentidos habituales de refu- gio frente al clima y frente a las intrusiones a la privacidad como en los sentidos derivados de la situación particular de wright en ese momento, que se sentía tratado hostilmente por la sociedad y personalmente desorientado. n por eso no es de extrañar que los símbolos y los requisitos del refugio dominen en taliesin. la casa se construyó rodeando la ladera de la colina, con su parte de atrás contra el muro; su imagen dominante siem- pre ha sido la de sus tejados protectores, tejados que emergen al azar de la vegetación y que tie- nen la pendiente de la propia colina; la línea de los aleros es continua y está muy próxima al suelo en el lado hacia donde sube la pendiente. los únicos rasgos que competían con la horizontalidad de los tejados eran las masas verticales de las chimeneas de piedra, que, al señalar los lugares de reunión del interior, reforzaban el simbolismo de refugio. n en relación con esto, thomas beeby enumera una serie de elementos de taliesin que sugieren un dolmen, desde los tejados de la secuencia de en- trada, apoyados en pilares de piedra, hasta las pro- pias chimeneas, con su dintel también de piedra. en definitiva, considera que toda la casa es análo- ga a un dolmen, “la primera construcción espacial del hombre, una cueva fabricada”. n f taliesin. patio

valladolid en , a la edad de sesenta y cinco años y en ple- na depresión económica, en un momento en que su actividad profesional y sus finanzas atravesaban un punto muy bajo, wright concibió la idea de transfor- mar taliesin en una escuela para arquitectos, crean- do la denominada ‘taliesin fellowship’. como señala stern oportunamente, aunque forzando un tanto la comparación: “al sustituir a los esclavos de la plan- tación de jefferson por los aspirantes a arquitectos y al ponerles a trabajar en las tareas domésticas y en la granja, wright extendió al siglo xx la arcádica visión de jefferson. su comunidad fue, en cierto sen- tido, una expresión de la idealización por wright de la experiencia de los pioneros americanos”. n en cualquier caso, podemos afirmar para concluir que si el político profesional y arquitecto aficionado tho- mas jefferson había orientado al oeste su vivienda en virginia —aunque volviendo la vista al clasicismo europeo para las referencias arquitectónicas—, el arquitecto frank lloyd wright, por su parte, avanzó físicamente hacia el oeste y creó una verdadera inte- gración paisajística, genuinamente americana, entre arquitectura y naturaleza al construir en

increasing numbers of inquiries about women while others believe the survey provides an opportunity to reinterpret their holdings and examine their acquisitions policies. still others are cooperating

among occupational injury cases. methods: an analysis of a state-based worker’s compensation claims data captured prescription reimbursement information of all injuries that occurred between january , and december , . payment information was followed over a -month period fol- lowing date of injury. a prescription sequence analysis was carried out to estimate treatment incidence rates of potential addiction due to narcotic analgesic use. results: of the , occupational injury cases, about % (n = ) received at least narcotic analgesic (therapeutic class h a). average length of therapy was days, with % of patients receiving nar- cotic analgesics for greater than days. the majority of nar- cotic prescriptions were for hydrocodone ( %). nine percent of patients received less than four different types of narcotic anal- gesics. from the prescription sequence analysis, we identified cases who received either methadone or clonidine, medications indicated for addiction treatment or detoxification. the inci- dence rate of receiving treatment for narcotic withdrawal or detoxification was per patients on narcotic analgesic therapy ( % ci: . , . ). among patients who received potential detoxification treatment, the median duration from ini- tiation of narcotic analgesic therapy to need for withdrawal or detoxification therapy was days. a cox proportional hazards model identified greater risk of suspected methadone use in oxycontin treated patients compared to other narcotic treated patients (p < . ). conclusions: to our knowledge, this is the first study that estimated the incidence rates of sus- pected addiction treatment due to narcotic analgesics used in the worker’s compensation population using sequential prescription analysis. the study has implications for developing strategies to manage narcotic analgesic prescribing practices and reduce the risk of addiction among injured workers who are narcotic anal- gesic users. pain pain—methods

overall convenience, ease of use, and effec- tiveness of managing pain from a patient’s perspective has not been determined. objectives: to develop a questionnaire to measure “ease-of-care” outcomes from the perspective of patients who use pca delivery systems for post-operative pain management. methods: we conducted qualitative interviews among a convenience sample of patients who had undergone hip or lower abdominal surgery and who received intravenous (iv) pca for their post-operative pain at thomas jefferson uni- versity medical center during june . a content analysis approach was used to identify domains of relevance and gener- ate an item pool. content validation of the draft “ease of care” questionnaire was performed by subjects who participated in the initial interviews. subjects were asked to rate the relevancy of each item on a scale of zero (not at all relevant) to four (highly relevant). each item was assessed for clarity and relevance, and revised as appropriate. cognitive debriefing interviews to evalu- ate patient experiences completing the instrument were conducted with a separate sample of patients from the same institution who completed the questionnaire approximately – hours post-surgery. results: the final patient ease-of-care ques- tionnaire consists of items and covers seven aspects associated with acute care pain management systems: control/self-efficacy, device function, mobility, quality of pain control, confidence, knowledge/understanding, and satisfaction. all items are scored on a -point likert scale. conclusion: we developed an instrument to capture “ease-of-care” outcomes among patients who use pca delivery systems for the management of their acute pain. the instrument is currently being used in clinical trials

and physical therapists’ experiences with patients using intravenous (iv) pca during july . a content analysis approach was used to identify general themes and specific issues and concerns associated with “ease of care” using the iv-pca. two item pools were generated for the development of two draft questionnaires, one from the perspective of nurses’ and the other from physical therapists, to address clinical and practical problems encoun- tered in routine care. items were selected based on relevance to the underlying concepts, clarity of item, and the overall flow and comprehensiveness of the instruments. subjects who participated in the focus group sessions also participated in a cognitive debriefing of the draft questionnaires. results: the final nurse and physical therapist ease-of-care questionnaires each consist of items that capture aspects of care delivery associated with acute care pain management systems. all items are scored on a -point likert scale. conclusion: we developed two instru- ments to capture “ease-of-care” outcomes among health-care providers to be used in upcoming studies of alternative pca delivery systems for the management of post-operative pain. the instruments are currently being used in clinical trials comparing two pca delivery systems. results will be used to examine the instruments’ psychometric properties. respiratory

donors, as cord blood, can be alternative donor sources in stem cell transplantation (sct). severe gvhd, however, has interfered the progress of haploidentical sct (haplosct). to deal with this strong gvhd, t cell depletion has usually been used in us and european countries. in order to pursue the controllable gvl effect by t cells, we have performed unmanip- ulated haplosct using myeloablative or reduced intensity precondi- tioning regimen accompanied with intensified gvhd prophylaxis. in this meeting, we will summarize our experience of haplosct for more than ten years. patients: from august to september , we have performed cases of haplosct (all cases were hla - antigen mismatched in gvh direction). patients’ characteristics are sex: male , female , age: - years old (median ), disease: aml/mds , all , ml , others . % of cases underwent sct in non-complete remission (non-cr) state. patients under years old underwent mye- loablative preconditioning regimen consisting of flu/ca/cy/ tbi gy (haplo-full, n ), and patients over years old or with comorbidities or repetitive sct (including second to fifth sct) underwent reduced intensity preconditioning regimen consist- ing of flu/(ca)/bu/atg or flu/(ca)/mel/atg (haplo-mini, n ). high dose ara-c (ca) was optional to reduce tumor burden. as atg, atg (fresenius) mg/kg, or thymoglubulin (genzyme) - mg/kg were used. gvhd prophylaxis consisted of taclolimus (tac), methylprednisolone (mpsl) mg/kg/day, short term mtx, and mycophenolate mofetil (mmf) mg/kg/day in haplo-full, and tac, mpsl mg/kg/day in haplo-mini, respectively. for elderly pa- tients over years old in haplo-mini, mmf was added. results: hematopoietic engraftment in haplosct was as rapid as that in hla-identical sct, except ten cases of graft rejection. acute gvhd (grade ii-iv) was observed in %. overall survival in five years is % in haplo-full and % in haplo-mini, respectively. if limited to cr cases, overall survival reached over % in haplo- mini. there is no difference in survival rate among patients’ diseases. discussion: unmanipulated haplosct is feasible and effective for refractory diseases. atg dose used in haplo-mini is critical, and rather low compared with that of european cases reported so far. a step approach to myeloablative haploidentical hematopoietic stem cell transplanation (hsct): report of a phase ii trial

patients for your patients by dan hurley may , the science explainedarticle in brief stroke neurologists at major medical centers reported an increased incidence of serious large vessel strokes in young covid- patients. not all the experts agree on the reasons why. dr. laura k. stein, in personal protective gear, worked straight -hour days in the emergency department at mount sinai hospital. a sharp increase in the incidence of serious large-vessel stroke among covid- patients under age has been reported by the largest medical system in new york city. the report, in a letter to the editor of the new england journal of medicine published on april , described a two-week period in which five patients between the ages of and presented to the mount sinai health system with new-onset symptoms of large vessel ischemic stroke. (none had serious symptoms of covid- , which was diagnosed only upon testing.) their mean score at presentation on the nih stroke scale was , which is consistent with a severe stroke. by comparison, the two-week average for such cases at mount sinai during the previous year was just . patients, according to the letter. thus, the five cases between march and april represented a seven-fold increase over the usual rate. outcomes have been serious, with two discharged to a rehabilitation facility, one still in the stroke unit, and only one having returned home. the remaining patient, described in the paper as experiencing multi-organ failure, has since died. the poorer-than-average outcomes were attributed in part to the patients' delay in seeking medical care. the youngest, a female, presented at the hospital hours after symptoms began, due to fear of covid- . another presented hours after symptom onset. two presented at eight hours. the remaining patient presented after just two hours. some stroke neurologists at other hospitals around the country told neurology today they are seeing a similar trend, consistent with an increased risk of clots forming in other organ systems; they are now recommending that all patients with covid- be treated with heparin or other therapy as a preventive measure. not all stroke neurologists, however, are convinced that the trend is real. rather than an increase, some say they are seeing a sharp decline in strokes generally, especially mild strokes or transient ischemic attacks, in keeping with a broad decline in emergency department visits of all kinds other than those involving covid- . even coauthors of the new report agreed that it's too early to be sure what the true link is between covid- and stroke. “we think there's a connection—we can't be certain, but it does seem to be real,” said stanley tuhrim, md, professor of neurology and director of the division of vascular neurology at mount sinai hospital. “and from speaking with colleagues around the country, i don't think it's an experience unique to mount sinai or even to new york city.” another report, now under review, involves a dozen stroke patients who were covid- positive and treated at thomas jefferson university hospitals in philadelphia between march and april . “these are all preliminary results,” said pascal jabbour, md, professor and chief of the division of neurovascular and endovascular neurosurgery in the department of neurological surgery at the sidney kimmel medical college at thomas jefferson university. “in general, you cannot draw conclusions from a small case series. but in pandemics like this, everything moves quickly. if we see something unusual, we need to investigate it and report it.” dr. jabbour is now in the process of collaborating with other centers in the united states and europe on a larger analysis of strokes in covid- patients, he said. nejm case the case described in greatest detail in the new england journal of medicine series from mount sinai involved a previously healthy -year-old woman who presented to the hospital with an nihss score of . she had previously developed cough, headache, and chills lasting one week, and then had dysarthria with both numbness and weakness in the left arm and left leg, which progressed for hours before she finally went to the hospital. ct and ct angiography revealed “a partial infarction of the right middle cerebral artery, with a partially occlusive thrombus in the right carotid artery at the cervical bifurcation,” the letter stated. “patchy ground-glass opacities in bilateral lung apices were seen on ct angiography, and testing to detect sars-cov- was positive. antiplatelet therapy was initiated; it was subsequently switched to anticoagulation therapy. stroke workup with echocardiography and magnetic resonance imaging of the head and neck did not reveal the source of the thrombus. repeat ct angiography on hospital day showed complete resolution of the thrombus, and the patient was discharged to a rehabilitation facility.” the letter noted that a report from wuhan, china, pre-printed in the lancet, described the incidence of stroke among hospitalized covid- patients at about percent. large-vessel stroke was also reported in association with the sars-cov- outbreak in singapore. in just the two weeks since the mount sinai letter was submitted to the new england journal of medicine, three additional cases of large-vessel stroke in young patients with covid- have presented to the hospital there, according to the letter's first author and neurologist thomas j. oxley, md, phd, an instructor and director of innovation strategy for the department of neurosurgery at mount sinai. “when young patients present with a large-vessel stroke, we would normally expect to see substantial risk factors,” he told neurology today. “most of these patients did not have any.” two of the patients had no risk factors for stroke: a -year-old man had undiagnosed diabetes and a -year-old man had a mild prior stroke and diabetes. the person who died, a -year-old man, had hyperlipidemia and hypertension. in addition to the five patients under age described in the letter, close to other patients, of all ages, both patients positive and negative for covid- , presented at mount sinai with large-vessel strokes during a recent three-week period, according to neurologists there. “it's probably close to patients in three weeks,” said laura k. stein, md, an assistant professor of neurology who serves as an attending stroke neurologist at mount sinai hospital. “a little over half were covid positive. many were young and likely don't have the same risk factor we typically see.” dr. stein expressed concern that outcomes for covid- patients appear to be worse than she would normally expect. “we give them tpa and thrombectomy but then they sometimes develop really bad swelling of the brain and a catastrophic outcome,” she said. “it's too early to tell if that's real or just an impression, but it's a concern right now that we're not seeing the same outcomes.” on the other hand, she has also seen healthy young people with covid- present with a clot in large vessel, but one that does not fully occlude. “they are treated with full-dose anticoagulation, and when we repeat the ct angiogram, we see that the clot is gone. it's quite remarkable.” to better understand what is going on, she said, “we're embarking on an ambitious effort to study what we're seeing more closely. we want to compare people with stroke and covid- to stroke without covid- . we also want to understand the difference between people who have mild or incidental covid- with stroke, and those who have really severe covid and then suffer a stroke or other thrombotic event.” dr. stein spoke on saturday, april , after completing days as the attending stroke neurologist at mount sinai hospital. “twelve straight days,” she said. “it was exhausting, but exciting. this is why i went into medicine. we were getting in at every morning; some days i didn't leave my office till : at night.” mechanisms and treatments a potential explanation for why strokes should be occurring in seemingly healthy young people was offered in a paper published ahead of print in the lancet on april . researchers based at university hospital zurich noted that the sars-cov- virus infects hosts via the angiotensin-converting enzyme (ace ) receptor, expressed not only in the lungs but also in the heart, kidney, intestine and endothelial cells. the swiss researchers described three cases in which they observed direct viral infection of the endothelial cells and diffuse endothelial inflammation. “covid- -endothelitis could explain the systemic impaired microcirculatory function in different vascular beds and their clinical sequelae in patients with covid- ,” the paper stated. “this hypothesis provides a rationale for therapies to stabilize the endothelium while tackling viral replication, particularly with anti-inflammatory anti-cytokine drugs, ace inhibitors, and statins.” another possible mechanism behind the apparent increased risk of stroke was described by dutch researchers in a paper published online on april in the journal thrombosis research. in icu patients with proven covid- pneumonia, a composite outcome of either symptomatic acute pulmonary embolism (pe), deep-vein thrombosis, ischemic stroke, myocardial infarction or systemic arterial embolism was seen in percent, a figure they called “remarkably high.” at the main campus weve seen about , patients with covid- . were still collecting and analyzing our data, but it seems to be around the order of percent of them having a stroke. if you consider these are very sick people with lots of inflammation, thats not actually very high.”—dr. babak navi “our findings reinforce the recommendation to strictly apply pharmacological thrombosis prophylaxis in all covid- patients admitted to the icu,” the paper concluded, “and are strongly suggestive of increasing the prophylaxis towards high-prophylactic doses, even in the absence of randomized evidence.” as a result of such findings, mount sinai instituted a new protocol earlier this month to raise prophylactic doses of heparin in some covid- patients to that usually given to dissolved clots, even before any such clots occur. “we expect there's a problem either with the coagulation system or the endothelial lining of their vessels,” dr. tuhrim said. “if there's a large-vessel occlusion amendable to thrombectomy, we certainly do that. in addition, we are anticoagulating these people. the hospital has developed a protocol, a very complicated algorithm, but it boils down to using anticoagulant with lovinox or one of the newer oral anticoagulants in patients we might not otherwise have treated.” while many other hospitals around the world are following a similar strategy, dr. tuhrim cautioned: “it's too soon to tell whether the strategy being deployed worldwide will turn out to be beneficial. it's a question of balancing the potential benefit against the risk of increasing hemorrhage.” steven r. levine, md, faan, distinguished professor of neurology and emergency medicine at suny downstate health sciences university and chief of neurology at university hospital of brooklyn has proposed a clinical trial to compare the approaches. “you've got every recipe in the book for preventing clotting right now,” dr. levine said. “some are giving aspirin, some are giving low-dose tpa, some are giving subcutaneous heparin. i've proposed a clinical trial with a standardized protocol of two or three treatments and an interim analysis so we can eliminate the ones that aren't working and find the optimal antithrombotic or anticoagulant.” collateral damage? whatever the cause of the increased risk of stroke associated with covid- , dr. jabbour at thomas jefferson said that both the presentation and outcome are often worse than in other strokes. “usually these covid- patients present with more than one vessel that is blocked,” he said. “we also notice that the outcome of these patients isn't so good. in our series, the mortality was around percent. despite the fact that we are opening the vessels, they end up having another major stroke. their blood keeps clotting so quickly.” aside from mechanisms directly mediated by sars-cov- virus, another factor at play is the delay in presentation seen at mount sinai and elsewhere. “we see patients presenting late,” dr. jabour said. “if they come too late, we can't help them.” babak navi, md, associate professor of neurology and neuroscience at weill cornell medicine, division chief of stroke and hospital neurology, and medical director of the weill cornell stroke center, said that he, too, has seen many strokes in people with covid- , but that most are older and already critically ill from the viral infection. “there are some younger people who have had vascular events and also tested positive for covid- ,” he said, “but that's pretty rare despite the recent interest in this area. we're in the middle of the epicenter. at the main campus we've seen about , patients with covid- . we're still collecting and analyzing our data, but it seems to be around the order of percent of them having a stroke. if you consider these are very sick people with lots of inflammation, that's not actually very high.” he agreed, however, that covid- patients who do have a stroke tend to fare poorly. “a lot of that has to do with respiratory failure and other end-organ problems,” he said. “in some cases, the strokes are the fatal event, but these are very sick people.” dr. navi called for better-designed studies to determine the true risk and best strategies for preventing and treating strokes in covid- . “i think we need high quality, rigorous studies that are well controlled,” he said. “making strong statements based on small, single center case series without comparison groups is problematic. case series are useful in raising the suspicion for a novel or unique association or risk factor, but they need to be validated in methodologically strong studies. we're not there yet.” ashutosh p. jadhav, md, phd, associate professor of neurology at the university of pittsburgh medical center, said that he is not seeing a rash of covid- patients with stroke. in fact, the number of stroke admissions across a -hospital network in the area fell by about percent in march compared to previous years, although the number of large-vessel occlusions was more or less flat. “the way i interpret that is that we are not seeing the milder strokes, but the severe strokes are still coming in,” dr. jadhav said. the likely result, he said, is that people who could benefit from treatment to prevent a second stroke are not getting it. “people are not coming in to get the medical attention they need, because they're afraid to interact with the health system,” dr. jadhav said. “i call it collateral damage. in our part of the country, that's more impactful than covid- itself. it's probably hurting more people than covid- will.” even in new york city, dr. navi agreed that patients' fear of going to the hospital is cause for concern. “i actually think that's a more concerning phenomenon,” he said. “the people with tia and minor stroke are in my experience more likely to not call and seek medical attention. those are people we could potentially intervene on with evidence-based proven strategies who now we often cannot because they present to the hospital too late.” link up for more information • oxley tj, mocco j, majidi s, et al. large vessel stroke as a presenting feature of

jefferson university, philadelphia, pa, usa. regulation of mitochondrial motility by milton-like proteins, oip and grif grif and oip are mammalian homologs of milton, a kinesin-binding protein that forms a complex with miro gtpase, an integral outer mitochon- drial membrane ef-hand protein. kinesin, milton and miro have been proposed to function together in the movement of mitochondria along the mi- crotubules. we report here the influence of overexpression of oip and grif on mitochondrial motility and its inhibition by agonist-induced cyto- plasmic [ca þ] ([ca þ]c) signals in h c cells. ha-tagged oip and grif were overexpressed at similar level and were localized to the mito- chondria as detected by immunocytochemistry. in oip and grif overex- pressing cells, elongated mitochondria with varied degree of aggregation were visualized both in live and in fixed, immunostained samples. mitochondrial motility at resting ca þ (< nm) was greatly enhanced by oip and to a lesser extent by grif ( . . and . motility units, respec- tively against a control value of . . motility units). furthermore, the ca þ-dependent inhibition of motility during stimulation by vasopressin ( nm) was suppressed by overexpressed oip ( . . %), whereas grif ( . . %) had no significant effect compared to control ( . . %). overexpression of oip or grif did not alter either basal [ca þ]c or agonist-induced [ca þ]c levels measured by fura . collectively, these data show that both oip and grif can modulate mitochondrial motility presumably, by promoting the association of mitochondria with the motor proteins. furthermore, oip seems to have greater efficacy in the control of mitochondrial movements. -pos board b mitochondrial localization and function relationship gyorgy csordas , sudipto das , peter varnai , tamas balla , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, school of medicine, budapest, hungary, nichd, nih, bethesda, md, usa. mitochondrial contribution to cell signaling and function relies on the associ- ation and local communication of mitochondria with the er and the plasma membrane (pm). we have recently shown that the local ca þ communication between er and mitochondria is supported by interorganellar tethers, and cre- ated synthetic linkers that connected the outer mitochondrial membrane (omm) to the er and sensitized mitochondria to er ca þ release. to study the kinetics and short-term effects of the linkage formation, we have now de- vised fluorescent protein pairs targeted to the omm and er or pm containing fkbp or frb domains. rapamycin causes heterodimerization of these pro- teins to form omm-er or omm-pm bridges. confocal imaging of the induc- ible fluorescent linker pairs revealed increased association of er or pm-patches with the mitochondria within minutes of rapamycin exposure. the linkage formation between the er and mitochondria was followed by a decrease in mi- tochondrial motility (> % in min) and by sensitization of mitochondria to ip receptor-mediated ca þ release. linkage formation between pm and mitochondria also suppressed mitochondrial motility. the initial kinetics and spatial distribution of linkage formation could be followed via recording fret between cfp-and yfp-containing linker partners. a longer version of the linker was found to show faster increase of the fret signal, supporting the idea that the rate of linkage formation positively correlates with the tight- ness of the er-mitochondrial contacts. currently, we are using the fret kinet- ics to visualize the areas of close er-mitochondrial interface and study its relevance in the ca þ signal propagation to the mitochondria. thus, inducible interorganellar linkers provide a tool to assess the distance between organelles in live cells, to establish rapid changes in the subcellular distribution and dynamics of the organelles and to evaluate the ensuing changes in organellar and cell function. -pos board b bak/bax-dependent apoptotic signaling in vdac -/- cells soumya sinha roy , william j. craigen , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, baylor college of medicine, houston, tx, usa. bid, a pro-apoptotic bcl- family protein, upon activation forms truncated bid (tbid) that binds to the outer mitochondrial membrane (omm) and engages bak/bax-dependent release of cytochrome c (cyto c) and other intermembrane space proteins from mitochondria to the cytosol to induce apoptosis. the volt- age-dependent anion channel (vdac) is the major permeability pathway for metabolites and ions in the omm but its role in the tbid-induced omm perme- abilization remains controversial. previously we reported that among the vdac isoform-specific knockout mouse embryonic fibroblasts (mefs), only vdac -/- mefs lack tbid induced complete cyto c release and loss of djm. here we show by single cell fluorescence imaging that permeabilized vdac -/- mefs expressing cyto c-gfp were resistant to tbid ( nm)-induced cyto c-gfp release. furthermore, by rescuing vdac -/- mefs with vdac the tbid-induced cyto c-gfp release was restored. in addition, tbid adenovirus infection caused less cell death in intact vdac -/- mefs than in wildtype (wt) mefs. it has been reported that vdac is required for proper targeting of bak in omm. indeed, bak did not appear in the membrane fraction of vdac -/- mefs. along this line we show that permeabilized bak -/- cells were more resistant to tbid induced cyto c release and loss of djm than wt and bax-/- mefs. strikingly, washout of the cytosol further desensitized the bak-/- mefs to tbid. unlike vdac -/- mefs, the bak-/- mefs constitutively overex- pressed bax that was primarily localized in the cytosol. however, recombinant bax ( nm) could induce cyto c release and depolarization in vdac -/- mefs and also supported the tbid-induced cyto c release. thus, in vdac -/- cells bak does not localize to the mitochondria and fails to interact with tbid and does not allow a compensatory increase in bax. the combination of these two mechanisms greatly attenuates tbid-induced omm permeabilization and apoptosis. -pos board b mitochondrial fusion-fission dynamics during hypoxia/reoxygenation xingguo liu, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. structural, biochemical, and functional abnormalities of mitochondria during hypoxia/reoxygenation (h/r) are widely believed to be important pathogenic factors that underlie cell injury. however, mitochondrial fusion-fission dynam- ics responses to h/r are unclear. we investigated the effect of h/r and chem- ical hypoxia evoked by kcn on cellular atp, djm, and on mitochondrial morphology and fusion. sixty min h caused cellular atp decrease to %. djm showed progressive decrease during h, gradually improved in the first minutes r and decreased again during longer r. mitochondrial fusion activity decreased to % during h and to % during r. in addition, anomalous fusion (autofusion and fusion at multiple sites among - mitochon- dria) produced donut-shaped mitochondria during r. cyclosporine a (csa), an inhibitor of the permeability transition pore (ptp) relieved the fusion inhibition ( %) and prevented donut formation during r. five mm and mm kcn could induce cellular atp decrease to % and %, and djm decrease to % and %, respectively. depolarized mitochondria were associated with donut-formation in mm kcn, and with massive swell- ing in mm kcn. fusion activity decreased to % in mm kcn and % in mm kcn, respectively. neither h nor kcn evoked cleavage of opa , the mitochondrial inner membrane fusion protein. thus, both physical and chem- ical h induced respiratory inhibition to gradually lower djm and cellular atp level, and caused fusion inhibition that was not dependent on opa cleav- age. this is sharp contrast of the uncoupler-induced fusion inhibition that has been attributed to the rapid djm dissipation-induced opa cleavage. a conse- quence of ptp opening, the matrix swelling seems to be a key to donut forma- tion since this could be evoked by both mastoparan, a potent ptp activator and by valinomycin, a potassium ionophore. -pos board b governing respiration: tubulin’s c-terminus interaction with vdac kely l. sheldon , dan l. sackett , claire monge , valdur saks , sergey m. bezrukov , tatiana k. rostovtseva . lpsb, nichd, the national institutes of health, bethesda, md, usa, limb, nichd, the national institutes of health, bethesda, md, usa, joseph fourier university, grenoble cedex , france. mitochondria have long been known to localize within and move along the tu- bulin-microtubule network. it was shown that tubulin binds to isolated mito- chondria with high-affinity and specifically associates with the mitochondrial voltage-dependent anion channel (vdac). we found that nanomolar concen- trations of dimeric tubulin vastly increase vdac sensitivity to voltage allow- ing for vdac blockage at low transmembrane potentials. tubulin interaction with vdac requires the presence of anionic c-terminal tails (ctt) on the in- tact protein. tubulin with proteolytically cleaved ctts does not block the channel. actin, also an acidic protein but lacking ctts, does not induce vdac blockage. two synthetic peptides with the sequences of mammalian a and b brain tubulin ctt do not induce detectable channel closure up to mi- cromolar concentrations. these results suggest a completely new role for regulation of

disseminated lyme disease: perplexing symptoms in a gardener brooke e. salzman, md, amber stonehouse, md, and james studdiford, md the timely diagnosis of early disseminated lyme disease presenting as multiple secondary erythema migrans lesions is sometimes delayed because this stage is infrequently encountered in a general prac- tice. we report a case of a -year-old woman whose initial complaints of an erythematous, “burning” rash and flu-like symptoms led to several laboratory tests with no specific diagnosis. the correct diag- nosis was only made after sorting through other possibilities in the differential diagnosis. by reproduc- ing the medical images and reviewing the medical literature, we underscore the importance of including lyme disease in the list of diagnoses pertaining to diffuse skin rashes in the febrile patient. ( j am board fam med ; : – .) case report a -year-old woman presented to her primary care doctor in june with a -day history of numerous, oval, diffusely erythematous patches scattered across her chest, abdomen, back, and extremities sparing her palms and soles (see figures and ). the rash, which became more prominent after a hot shower or expo- sure to a warm, ambient environment, was also de- scribed as “burning” and “hot.” further, she reported a -week history of flu-like symptoms consisting of headache, neck pain, generalized body aches, fever, chills, and malaise. she also complained that her cheeks felt unusually hot and were bright red. she denied having any associated respiratory or gastroin- testinal symptoms. the patient denied a history of a recent tick or insect bite. however, on further questioning, she de- scribed herself as an avid gardener. she lives in a rural area of new jersey where deer sightings are frequent. the patient’s bilateral facial erythema, which was reminiscent of the classic “slapped cheeks” ap- pearance of parvovirus b- prompted serologic testing for this viral agent. a complete blood count and a comprehensive metabolic panel were also performed. the results were all normal except the liver function tests, which were mildly elevated with an alanine aminotransferase of u/l, aspar- tate aminotransferase of u/l, and alkaline phos- phatase of u/l. at a follow-up visit days later, because of the persistence of numerous ery- thematous plaques accompanied by fever, myalgias, and arthralgias, lyme disease (ld) was suspected and the patient was screened for borrelia burgdorferi antibody with the standard enzyme-linked immu- nosorbent assay. this was positive with a reported value of � (� . is considered positive). west- ern blot analysis for igm was positive and negative for igg, thus confirming acute, early disseminated ld. the patient was treated with mg of doxy- cycline twice daily for a period of days with resolution of her symptoms. on further monitor- ing, her liver function tests returned to normal. discussion this case describes a patient with secondary ery- thema migrans (em) associated with early dissem- inated ld. the vast majority ( % to %) of patients in the united states who present with early ld have only a single, primary em lesion which occurs at the site of a tick bite. primary em lesions typically

often appearing in or crops of similarly sized and shaped lesions. – secondary em lesions are generally lighter, smaller, less edematous, and have less central clear- ing compared with primary ems. , typically they first become apparent or intensify with elevations of body temperature. patients with secondary em without an obvious primary lesion may lack a host immune response to the bacterial antigen. , sec- ondary em lesions can appear on the head, face, trunk, and extremities, usually sparing the palms, soles, and mucus membranes. both early localized and early disseminated ld are usually accompanied by nonspecific, flu-like symptoms including myalgias, arthralgias, fatigue, headache, neck stiffness, and sometimes fever. , patients with secondary em may have more con- stitutional symptoms than those with primary em lesions alone. upper respiratory tract and gastro- intestinal symptoms are typically absent. the dif- ferential diagnosis for a diffuse, patchy, erythema- tous rash associated with flu-like symptoms can include urticaria, secondary syphilis, parvovirus b- , lichen planus, erythema multiforme, pityria- sis rosea, lyme disease, and fixed drug eruption. urticaria would probably not be associated with myalgias and arthralgias, as seen in our patient. our patient’s rash spared the palms and soles, unlike syphilis. the rash associated with parvovirus b- generally is limited to the cheeks. erythema mul- tiforme usually is described as iris or target-like vesicular lesions and typically involves the palms and soles. our patient did not have the fine scaling papules and plaques with collarettes typically seen with pityriasis rosea. health care practitioners located in areas of en- demicity for ld should especially become familiar with these early clinical manifestations. these geo- graphic regions in the united states include areas of the northeast (massachusetts to maryland), up- per midwest (wisconsin, minnesota), northern california, and oregon. most cases of ld occur during the late spring and summer, peaking in june and july. this time frame correlates with the nymphal stage of the life cycle of the ixodes tick, which accounts for the large majority of ld trans- mission. figure . numerous oval, erythematous patches scattered across this patient’s chest, abdomen, back, and extremities sparing her palms and

clinical findings, including the presence of a characteristic solitary em and a history of tick exposure in an endemic area. because of the high rate of false- negative results in the acute phase of ld ( %), routine use of serologic tests in patients with em is not recommended. such patients should be diag- nosed and treated for ld without further testing. , cases in which serologic testing may provide valu- able information include patients, such as ours, with clinical findings suggestive of early dissemi- nated ld or patients with prolonged constitutional symptoms (� weeks) suggestive of early ld with- out em. , when testing is indicated, both acute- phase and convalescent-phase ( weeks after the acute phase) serum samples should be tested using a -tiered assay recommended by the centers for disease control. with the -tiered assay, a positive or indeterminate screening test (ie, enzyme-linked immunosorbent assay) is followed by a more spe- cific confirmation test (ie, western blot). additional testing that may be ordered on pa- tients such as ours may include hepatic function panels. in the case of ld these tests (specifically transaminase determinations) are nonspecific mea- sures of liver inflammation and not indicative of specific liver pathology. such liver function test abnormalities have been reported to occur in % of patients with early disseminated ld. these are most often asymptomatic and resolve after weeks of appropriate antibiotic therapy. the recommended treatment for adult pa- tients with early localized or early disseminated ld (in the absence of specific neurologic mani- festations including radiculopathy, cranial neu- ropathy, mononeuropathy multiplex, meningitis, or encephalomyelitis, or advanced atrioventricu- lar heart block) is doxycycline ( mg twice per day), amoxicillin ( mg times per day), or cefuroxime axetil ( mg twice per day) for approximately days. conclusion it is important to consider lyme disease (ld) in patients who present with unexplained flu-like symptoms during summer months, particularly in areas endemic for ld. inquire about outdoor ac- tivities and routes of exposure when ld may be suspected. clinicians should be aware that early ld may present with a diffuse rash indicating dissem- inated infection. references . steere ac, sikand vk. the presenting manifesta- tions of lyme disease and the

of political liberalism. in this regard, his writings of the pre-revolutionary period allude to the ancient saxon constitution and to the natural rights of john locke. second, we expose hannah arendt’s assessment of the american revolution as a replica of classical republicanism, to the detriment of the thesis prevailing until , which places it within the context of classical liberalism. we assert that she interprets t. jefferson as representative of republicanism, highlighting in particular his thesis on the council system. revista internacional de pensamiento político - i Época - vol.

( ) y en the human condition ( ), defiende un modo de entender la política diverso del inaugurado con platón, el iniciador de la filosofía política . su posición es que desde platón la política se entendió como un medio para fines más elevados (en su caso, la paz y el orden para la actividad filosófica), todos ellos, con independen- cia de su contenido, se ubican fuera de la política . en otras palabras, a partir de la filosofía política, que platón inaugura, encontramos una versión precoz de la in- vasión de la razón instrumental, en per- juicio de la razonabilidad o la sensatez fronética. de allí el título del parágrafo de the human condition: “la tradicional substitución de actuar [acting] por hacer [making]” . fundando su interpreta- ción en poetas e historiadores previos a la escuela socrática, arendt entiende la política como un fin en sí mismo, como espacio de despliegue de la praxis con- junta (como algo distinto de la destreza técnica) y de la libertad como un hecho . arendt, �annah, �philosophy and politics”, . arendt, �annah, �philosophy and politics”, social research, vol. , no.

cf. pp. - , - . perfecta combinación de poderes hu- manos en sociedad, que la sabiduría fi- nita ha ideado [contrieved] y puesto en práctica para la preservación de la liber- tad y la producción [production] de la felicidad” . para b. bailyn, en los años previos a la revolución, los colonos ame- ricanos no entendían la palabra constitu- ción como lo podríamos hacer nosotros, como un documento escrito, o inclusive como un diseño de gobierno no escrito, pero deliberadamente elaborado, suma- do a una especificación de los derechos, que la legislación no puede tocar. por el contrario, concebían la constitución como el “orden [arrangement] constituido –es decir, pre-existente- de instituciones gu- bernamentales, leyes y costumbres, jun- to con los principios y los fines que las animan” . ese sentido de constitución era el invocado por lo colonos, cuando reclamaban a la madre patria por sus derechos usurpados. como dice pocock, citando precisamente on revolution, de arendt: “en defensa de su virtud contra la corrupción de la tiranía de la monarquía parlamentaria, los americanos empezaron a reconstituirse a sí mismos en una con- federación de repúblicas; hasta este pun- to su revolución fue una rinnovazione” , es decir, una restauración de libertades antiguas (constitution). en suma, mien- tras que los parlamentarios, abogados y jurisconsultos ingleses habían situado su reclamo históricamente sobre bases que antecedían a la monarquía, jefferson he- . adams, john, . adams, john, the political writings of john adams (edited with an introduction by george �. carey), regnery publishing, inc., �ashing- ton, ;

[…] sus argumentaciones presentan el delicado equilibrio entre ex- periencia histórica y verdad auto-evidente. y el verdadero riesgo es que las urgencias y necesidades racionales del momento podrían dominar [overpower] la veracidad del pasado” . es decir, ante la urgencia política, jefferson que era más hombre de estado que historiador, interpretó y editó los hechos efectuando un particular “uso de la historia”. vinculó directamente la suerte de las colonias con la recuperación de las libertades sajonas, en desmedro de la herencia normanda, que introducía . �ood, gordon, . �ood, gordon, the creation of the american republic, - , the university of north carolina press, chapel �ill and �ondon, (first edition ); cf. p. . . idem, cf. pp. - .. idem, cf. pp. - . premisas inconvenientes. creemos que esta estrategia introdujo inconsistencias en el argumento de thomas jefferson. en lo que sigue, mostraremos la ambigüedad del discurso del autor en sus escritos. . perplejidades del discurso de jefferson para thomas jefferson, la metrópoli usur- pó los derechos de los colonos, expoliando riqueza de las tierras coloniales para hacer frente a la descomunal deuda pública con- traída para financiar la guerra de los siete años contra francia ( - ). dice jefferson: “ellos [el parlamento] hablan de hacer cumplir las leyes, cuando están violando la constitución […]. ¿acaso sus ministros -¡señor!- descubrieron minas de inextinguible riqueza en américa, para ex- poliar, para cancelar nuestra enorme deu- da nacional?” . la metrópoli pretendía cancelar sus deudas mediante la entrega de tierras, y la alta burguesía terratenien- te virginiana, a la que jefferson pertene- cía, quería defender su propiedad ante la amenaza de expropiación. de allí que je- fferson avale una aristocracia propietaria y terrateniente intocable. pero esta idea -admítase- responde al paradigma de la monarquía feudal, que claramente entra en colisión con su permanente invocación de los derechos sajones, como previos a (y posteriormente contaminados por) la legislación normanda. quizá jefferson era consciente de esta inconsistencia en su argumentación y, por eso, usó como prin- cipal argumento la voracidad y la extra . cf. thomas jefferson. cf. thomas jefferson the works of thomas jefferson, federal edition (new york and lon- don, g. p. putnam’s sons, - ). vol. .

en el centro: new jersey, new york, delaware, pen- silvania; en el sur: virginia, maryland, carolina del norte, carolina del sur y georgia. en una palabra, la noción de revolución no remite a la exención de los abusos o al control de los órganos de poder, circuns- tancia que alude a las libertades negativas (incluso el derecho a la representación para decidir sobre las cargas impositivas), sino a la libertad política y a la participación en los asuntos públicos. entre las cualidades que la pensadora resalta en el suceso americano es que la guerra de la independencia, el proceso de liberación o rebelión -consustancial a una revolución, pero no su condición suficiente- no arrojó a los colonos a un estado de naturaleza, para decirlo en pa- labras de hobbes, sino que los encontró ya organizados en “sociedades políticas” o “cuerpos políticos civiles” . tales aso- ciaciones preliminares regulaban sus asuntos con relativa autonomía y -lo que resalta arendt- recibieron la sanción de las cartas reales con posterioridad a su institución espontánea (no tutelado ni guiado por una autoridad superior); fue- ron súbditos ingleses por casi años hasta su independencia, por lo que no estaban investidos de soberanía. combi- naban, entonces, libertad y no soberanía. en on revolution, arendt interpreta la experiencia colonial y pre-colonial de los eeuu con sus propias categorías de pensamiento político, fraguadas sobre el carácter ejemplar de la polis griega y de la civitas romana. pertrechada de los ins- trumentos teóricos antedichos, la autora halla en los orígenes de su patria adoptiva una riqueza política y una experiencia re- volucionaria, que no ha sido debidamente enaltecida. animada con este espíritu, re- gistra en estas “sociedades políticas” co- loniales, en las “repúblicas elementales” . cf. idem, pp. , - , - .. cf. idem, pp. , - , - . . cf. idem, pp. , , .. cf. idem, pp. , , . revista internacional de pensamiento político - i Época - vol. - - [ - ] - issn - x de thomas jefferson y en el “civil body politik” de la fórmula del mayflower una réplica moderna de esas primeras institu- ciones políticas libres del mundo clásico de las que somos herederos . la guerra por la independencia, la desvin- culación de la corona inglesa, a diferencia de lo que sucedería en francia, no barrió los privilegios de los antiguos estamentos y ordenes, que -pertenecientes al antiguo régimen- constituían los patrones de una organización obsoleta;

es decir, en la salvaguarda de las libertades civiles, mediante garantías constitucionales. o sea, la posición de arendt es que el aspecto crucial del pro- ceso revolucionario en los eeuu no yace en la raíz liberal clásica, sino en la discu- sión por la mejor forma de gobierno o por la distribución más sabia de los poderes. veremos que su posición sobre la revolu- ción es compatible con su interpretación �herencia del pueblo inglés�”. véase, molían, tomás �burke y las concepciones conservadoras de la democracia”, crítica & utopía, latinoame- ricana de ciencias sociales, número , buenos aires, septiembre, . se consultó la versión on line publicada por la red de bibliotecas vir- tuales de ciencias sociales de américa �atina y el caribe de la red clacso: www.biblioteca- virtual.clacso.org.ar/ar/libros/criticayutopia.htm véanse especialmente pp. - . edmund burke argumenta sobre los derechos de los ingleses, es decir, los derechos y libertades que se heredan por tradición en reflections on the french revo- lution. véase, http://oll.libertyfund.org/title/ especialmente, pp. - , . en esta última leemos: “in the famous law of the rd of charles i. called the petition of right, the parliament says to the king, �your subjects have inherited this freedom», claiming their franchises, not on abstract principles as the «rights of men», but as the rights of englishmen, and as patrimony de- rived from their forefathers”. . cf. sheldon, garret, �., . cf. sheldon, garret, �., the political phi- losophy of thomas jefferson, op. cit.;

se trata, entonces, de una estabilidad relativa. arendt, al igual que jefferson, destaca particularmente la in- tensidad con que las nuevas generacio- nes (“los recién llegados” ) “toman por asalto” el mundo, que los adultos les en- tregamos en custodia , y cuya solidez ha de ser lo suficientemente vigorosa para encauzar su praxis -la estabilidad relativa- al tiempo que ha de dejar espacio para cambiar los aspectos, otrora operativos y significativos, pero hoy obsoletos. la categoría clave del ámbito público y político es la acción; designada con los vocablos griegos praxis y lexis (literalmen- te: actuar y hablar), la acción responde a la condición humana de la pluralidad . hablar y actuar siempre acaece entre los hombres. por su carácter impredeci- ble e ilimitado, no podemos dominar por completo los resultados o de las conse- cuencias de la praxis, precisamente por- que es praxis mancomunada (“action in concert”) . es decir, no controlamos sus implicancias porque hablar y conversar . cf. arendt, �annah. cf. arendt, �annah, the human condition, op.cit.;

sin embargo, las instituciones legítimas son “manifestaciones y materializaciones de poder; se petrifican y decaen tan pronto como el poder vivo del pueblo deja de sostenerlos” . en consecuencia, el poder no sólo se manifiesta originariamente en el momento fundacional, cuando muchos se reúnen para hablar o actuar (praxis y lexis), sino que debe perdurar activo como savia que vivifica las instituciones. dicho con arendt, el poder también es “aquello que mantiene en existencia el espacio público [public space], el espacio potencial de aparición que acaece entre los hombres, en calidad de agentes y de oradores”. el ámbito público es un es- . cf. arendt, �, . cf. arendt, �, the human condition, op. cit.;

como tales eran las instituciones cruciales de la nueva re- pública. la vida del hombre libre -apunta arendt- necesita de espacios acondicio- nados para congregarse en calidad de . cf. �annah arendt, . cf. �annah arendt, on revolution, op. cit.;

en esto radica -para hannah arendt- la relevancia de la praxis manco- munada como expresión más excelsa de nuestra humanidad. para hannah arendt esta actividad -esencialmente política- es un fin en sí mismo. no necesita remitirse a los propósitos y objetivos, para ser sig- nificativa. su especial interés en el jeffer- son republicano, con sus ideas sobre los municipios, la participación activa garan- tizada, y con la división de la república en consejos, no se debe a una actitud nostál- gica de las decisiones directas de las an- tiguas polis griegas, pese a su reluctancia hacia la representación política. arendt desea rescatar otra cosa. las sociedades o clubes revolucionarios en francia, y los wards virginianos no se establecieron ne- . cf. idem, p. .. cf. idem, p. . . cf. idem, p. .. cf. idem, p. . . cf. idem, p. .. cf. idem, p. . revista internacional de pensamiento político - i Época - vol. - - [ - ] - issn - x cesariamente para la toma de decisiones, o para las funciones ejecutivas; su obje- tivo no era solo el gobierno o la adminis- tración de un municipio, sino asegurar un ámbito para la discusión, el debate y la conversación. en on revolution, por ejemplo, arendt valora particularmente un club francés que se había impuesto a sí mismo la prohibición de tener algún tipo de influencia en la asamblea gene- ral. el club existía solamente “para con- versar sobre [los asuntos públicos] y para intercambiar opiniones, sin la necesidad de plantear propuestas, hacer peticiones, nombramientos, y cosas por el estilo” . de la misma manera, los consejos eran un espacio de libertad, un lugar donde la gente se podía reunir y discutir sobre cuestiones del día, comunes a todos. su importancia no recae -como vemos- en sus logros, o en los fines que consiguen, sino en lo que fomentan y promueven. como espacios institucionales de expe- riencia política organizada, los consejos ideados por jefferson, recreaban y fo- mentaban la emulación de las pasiones y acciones pasadas; ofrecían la experiencia de la acción libre y de la felicidad pública, que son posibles solamente en el proceso de la acción conjunta y de la conversación con otros. veamos la cuestión en los es- critos de t. jefferson. en notes on the state of virginia ( ), jefferson escribió que deseaba “dividir cada condado en pequeños distritos de cinco o seis millas cuadradas, llamados cientos [hundreds]” . un año más tar- . cf. idem, p. .. cf. idem, p. . . �hundreds” se refiere a cien varones cabe- zas de familia. en origen, la propuesta tenía fines educativos. �this bill proposes to lay off every country into small districts of five or six miles square, called hundreds and in each of them to establish a school for teaching, reading, writing, de, con la aprobación de la land act de (que establecía que una sección por municipio debería reservarse para propó- sitos educativos), la idea se convirtió en ley. treinta años más tarde, cuando las tres ramas del gobierno federal -ejecuti- vo, legislativo y judicial- habían crecido desmesuradamente en poder en relación a los gobiernos locales, jefferson insistió en la relevancia política de su idea de los wards, que combinaba todos los requisi- tos de una república en miniatura: parti- cipación y auto-gobierno en un territorio pequeño. en la carta del de enero de dirigida a joseph cabell, jefferson alude al estado de virginia y le confía su antiguo anhelo: “hace tiempo que creo que la subdivisión del condado [county] en consejos [wards] es la medida funda- mental para asegurar la continuidad del gobierno republicano” . dos años des- pués, el de febrero de , se dirigió al mismo destinatario precisando su pro- puesta en relación a la naturaleza de las funciones del consejo: “que al gobierno nacional le sea confiada la defensa de la nación y sus relaciones extranjeras y fe- derales. a los gobiernos estatales [se les confíen] los derechos civiles, las leyes, la policía y la administración de lo que le concierne generalmente al estado. a los condados les compete los asuntos [con- cerns] locales;

toronto guy renfro donnell guy r. donnell, oklahoma state university emeritus professor of political science, , died on novem- ber . for years he taught politics to students enthralled by his quick wit and carefree cynicism. students flocked to enroll in his classes, and when the time finally came for him to retire in , he was honored with a scholarship fund from which awards are granted annually in his memory. with guy donnelps passing, another gallant witness to pioneer times in the southwest is gone. his mother, iva may, came to texas with her parents after a nine-week trip by covered wagon from illinois. she married john donnell, whose father had fought with the missis- sippi regiment in the civil war. she strongly encouraged their three chil- dren to excel in school, and between them they went on to earn seven uni- versity degrees. when guy donnell graduated from saint jo high school, montague county, he was the valedictorian of his class. he studied for one year at what was then called north texas state teach- ers college in denton, after which, at the ripe age of , he secured the first of several teaching jobs in small county schools. living frugally, he managed to squeeze in semesters at college between teaching jobs. it took him nine years to get his bachelors degree, which was awarded by the university of oklahoma, and several more years to get master's and doctoral degrees from the uni- versity of texas in austin. when world war ii broke out, donnell joined the u.s. army air corps. he served as a flight com- mander at the aviation cadet center in san antonio, which was then regarded as the elite school for army aviators. donnell abhorred pomp and pretentiousness. he had a repu- tation for being kind and considerate to cadets, who were often the butt of harsh discipline administered by younger officers with heads freshly swelled at west point. thanks to friendships formed in those days, donnell received shortly after the war a welcome invitation to join the political science faculty at oklahoma a&m in stillwater. donnell became a mainstay of the political science department, which he managed almost single-handedly while the nominal head of the de- partment busied himself with more lucrative ventures. donnell planned the class schedules, attended count- less committee meetings, advised hundreds of students, and taught three or four courses a semester, all the time delighting students with wicked anecdotes and sarcasms he found it inadvisable to repeat outside of the classroom. his familiarity with state and local politics affected both his view of human nature and his view of academic political science. he would often merrily dismiss a piece of scholarly writing by compar- ing its author's intelligence unfavor- ably to that of his cat, cochise. donnell was a great favorite of faculty members of all departments. his election to serve on the univer- sity's faculty council testified to their respect for him. he himself took special pride, however, in his service on the university's athletic cabinet, appointment to which, as the only university committee from which faculty members drew any tangible benefits, was incontroverti- ble proof he was not a chump. after his retirement from the osu faculty donnell continued to fre- quent the campus and to regale friends and colleagues with amusing stories and outrageous insights. even as he coped valiantly with the loss of his wife, sue, and three serious ill- nesses, his intelligence and sense of humor never faltered. vigorous and charming into his ninth decade, he found a new and valued friend, mary elizabeth jones, who joined him in marriage and brought him new happiness. bertil hanson oklahoma state university cecelia kenyon cecelia marie kenyon (cele as she was more generally known) died in her home in northampton on janu- ary , . she was born in gainesville, georgia, in , and received her ph.d. from radcliffe in . she had come to smith the year before as an instructor and remained a member of the smith fac- ulty until she retired in . she was named the charles n. clark profes- sor of government in . her field was european and american political theory, and most of her scholarly writing dealt with the political theoretical arguments surrounding the birth of the ameri- can republic. for a variety of reasons she did not publish much, but the articles and books she did publisli have become classics in her field to be cited, discussed, and argued about by others. this is especially true of her seminal essay, "men of little faith: the anti- federalists on the nature of repre- sentative government," which was originally published in and then, expanded to over pages, served as an introductory essay to her edited volume the anti-federal- ists, published in . in recognition of her contribution to our understanding of the founda- tions of the american political order, cele was awarded an honorary degree by rutgers university in . in the same year, she spoke before the u.s. congress at a program marking the birthday of thomas jef- ferson, one of her heroes. two years earlier, in , she had been chosen to address the united states house of representatives at a program marking the th anniversary of the first continental congress. she also served as a member of the board of trustees of oberlin college, where she had received her b.a. degree. if cele was a creative scholar, she was also a respected and revered ps: political science & politics in memoriam teacher. she worked closely with her students, going over their examina- tions or papers with a fine-tooth comb, writing pages and pages of comments and spending hours and hours of her time with them. at the peak of her career she was an impor- tant model for many government majors, partly because they knew that, while demanding, she was also supportive and fair. and while she could be very serious, she also had a rich, wry sense of humor. as one of her former students wrote recently: my most favorite memory of cecelia kenyon is the lecture she gave on thomas jefferson in which she admit- ted to stealing two bricks from monti- cello on one of her pilgrimages there. this admission she made with a con- spiratorial grin and defiant toss of her head in front of over fifty saturday morning smith students. before that moment i felt mostly awe in her pres- ence. after that moment my awe was tempered by the warmth of her admis- sion. the steel trap mind was wedded to a very human heart. cecelia ken- yon has been, and remains, my most important memory of four years at smith. her influence on my life has reached far beyond the information she imparted. cele was also a wonderful col- league. she gave freely of her time to the college, fostering that faculty self- governance which has become its hall- mark, and she was elected to many key committees by the faculty. she loved smith and, therefore, insisted that the college live up to her very high standards of fairness and jus- tice. thus, although not confronta- tional by nature, and, indeed, rather shy, she said what she believed and stuck by it. for this reason cele was sometimes regarded with trepidation and annoyance, if also respect, by her colleagues and those college pres- idents who served while cele was here. she was the sometimes lovable and sometimes not so lovable bane of their existences. cele was, to use an old-fashioned word which she liked, a lady. she was invariably courteous to her opponents and soft spoken, inter- lacing her arguments with wryly humorous remarks, which during the height of her powers, often produced peals of laughter even from those with whom she disagreed. of course, we all knew that the velvet glove covered an iron fist. cele was also an old-fashioned lib- eral democrat. she hated both richard nixon and ronald reagan with a passion, not only because of their conservative social policies, but also because both of them, she believed, had violated the rule of law and its constitutional underpinnings. on the other hand, she was not par- ticularly sympathetic to radical critics of the american system and she was not a feminist. although very sensi- tive to discrimination against women of the kind she had experienced at harvard, she was quite angered by attempts to write off political theories because they had been con- structed by men. thomas hobbes was another one of her heroes and, insofar as she had made his thought hers, his gender was, she believed, unimportant, and he could be suit- ably revised to provide support for equality of opportunity for men and women. it was equality of oppor- tunity that cele sought. she was strongly opposed to quotas or even "goals." finally, she was passionately com- mitted to freedom of expression and academic freedom. she would, indeed, have echoed the words of jefferson: "here we are not afraid to follow truth wherever it may lead, nor to tolerate any error so long as reason is left free to combat i t . " many ascribe to that view when asked, but relatively few people in this world, a saving remnant, are willing to put themselves on the line defending unpopular speech when push comes to shove. cele was a member of that saving remnant. may her spirit long be with us. stanley rothman smith college horace b. jacobini h. b. (jack) jacobini died at the age of on august , , after waging a valiant battle against cancer. he came to southern illinois university at carbondale in after teaching at the citadel, the university of alabama (huntsville center), east central state college (oklahoma), and at the university of michigan on assignment at the uni- versity of the philippines. his pri- mary teaching interests and special- ties included international law, administrative law, jurisprudence, and the government and politics of southeast asia. he served on over eighty master and ph.d. committees, directing more than his share of theses and dissertations. he traveled widely, giving lectures and conduct- ing research throughout the world. jack was the author of numerous professional articles published in the united states and abroad. he penned eight books. completed just before his death, his tome, inter- national administrative law, is scheduled for publication by oceana in . his best known works are two editions of the widely adopted book, international law: a text ( / ). his father was an italian immi- grant who taught romance languages at fort hayes kansas state college, an institution where jack received his a.b. and m.s. degrees. it is perhaps this background that helps to explain jack's interest in and intense study of modern languages. his bedtime reading often included studying one exotic language or another so that he might better understand an obscure manuscript or converse with experts in their native tongue. jack was a modest man who dis- dained those who made too much of their academic pedigree. he was the first recipient of the ph.d. degree in political science at the university of kansas ( ) and a man who marched to his own intellectual drummer. he believed that scholars should pursue their own research agendas, without respect to existing paradigms or discipline orthodoxy. a thoroughly humane individual, jack always had time for his stu- dents, colleagues, and friends. his kindness to students was well-known but it was not until his death that many of us learned that he aided political refugees from foreign lands, providing food and shelter to the less fortunate. living the life of a gentleman- scholar, jack and his wife billie occupied a fine home and ranch/ farm not too many miles from the carbondale campus. in this idyllic setting, they nurtured four successful march michaela kleppinger independent scholar orcid: - - - doi . / . . denial of consent: the modern heir of sexual violence within slavery introduction on one night in , a pregnant nineteen-year-old girl named celia was, understandably, not feeling very well. on this same night, a man entered her room, and attempted to rape her, despite her efforts to convince him to spare her. acting out of fear and desperation, celia struck the man twice, accidently causing his death. celia’s actions were a clear case of self-defense–a justifiable homicide. however, celia was a slave and the man was her owner. the sixty-year-old widower, robert newsom, had specifically purchased celia to fulfill his sexual desires and had, there- fore, been raping her regularly. celia had pleaded and warned him that she might “hurt [newsom], if he did not quit forcing [raping] her while she was sick” but he did not listen; celia was his property, to do with as he wished. ultimately, celia was executed for murder–executed for fighting back against her own rapist. the institution of slavery is a stain upon the history and the psy- che of the united states and its people. at its core, it was inherently reliant upon an imbalance of power between the enslaved subject and the slave owner. the enslaved individual’s capacity to assert their own will was virtually nonexistent, allowing white male slave owners the op- portunity to exploit this discrepancy in order to take advantage of the enslaved women and girls under their dominion. the history of slav- ery in the united states is burgeoning with stories like celia’s of sexu- al exploitation and victimization at the hands of predatory white men without a thought or care for the well-being of the women and girls they violated and abused. it is from these roots of coercion and violence that myths and stereotypes proclaiming the sexual immorality of black wilma king, “prematurely knowing of evil things: the sexual abuse of african american girls and young women in slavery and freedom,” the journal of african amer- ican history , no. (july ): . michaela kleppinger women emerged, resulting in the discrediting and discounting of their word. for centuries, white men and society at large have ignored and repressed this history in an effort to avoid blame and deny culpability, leaving black women and girls vulnerable and targets of further victim- ization—an injustice that has veritably stripped them of their right to refuse consent. sexual violence and exploitation within the institution of slavery as william wells brown establishes at the beginning of his literary work, clotel or the president’s daughter, a narrative of the life of a fictional- ized enslaved daughter of president thomas jefferson: a slave is one who is in the power of a master to whom he belongs. the mas- ter may sell him, dispose of his person, his industry, and his labour. he can do nothing, possess nothing, nor acquire anything, but what must belong to his master. the slave is entirely subject to the will of his master, who may correct and chastise him, though not with unusual rigor, or so as to maim and mutilate him, or expose him to the danger of loss of life, or to cause his death. this reality of complete subjection was even more poignant for par- ticularly vulnerable enslaved women and girls. in the united states, white male slave owners took advantage of the power discrepancy be- tween themselves and their enslaved property in order to sexually har- ass, exploit, and assault the women and girls under their charge. as mary church terrell wrote in her article “lynching from a ne- gro’s point of view”: “throughout their entire period of bondage […] colored women were debauched by their masters”. slave owners did not consider their behavior as a form of violation or a breach of christian morality. based on their southern slaveholding principles, there was no question that they were well within their rights to use these women and girls as they so desired. as james hammond, a mid-nineteenth centu- ry writer and slave owner, who engaged in a sexual relationship with both his slave sally johnson and her daughter louisa, claimed: “i do not remember that i ever intentionally did wrong, i do not think that i

americans redefine sexual violence,” in redefining rape (harvard university press, ), . denial of consent: the modern heir of sexual violence within slavery ever deliberately or otherwise, wronged any human being”. in her anal- ysis of hammond’s behavior and professed beliefs, wilma king, in her work “‘prematurely knowing of evil things’: the sexual abuse of afri- cans american girls and young women in slavery and freedom,” sug- gests: “hammond’s introspection gives readers pause and may explain why some enslaved people endured suffering peculiarly their own when slaveholders seemed oblivious to it all, or did not see them as equally hu- man, or had no sense of religious morality or moral center” . in essence, within the institution of slavery, the sexual exploitation and victimiza- tion of black women and girls was not only accepted but the cultural norm. beyond expectations of providing physical labor, enslaved women and girls were considered perpetually sexually available and treated as brood mares. as harriet martineau details in her work “morals of slav- ery,” following her visit to the united states in the s, on plantations, “it was understood that the female slaves were to become mothers at fifteen” –at fifteen-years-old, scarcely out of puberty and certainly not fully into womanhood. slave owners could simply rape enslaved women and then profit from the results of this assault: with the growing population of slaves in the southern states of america, there is a fearful increase of half whites, most of whose fathers are slaveo- wners, and their mothers’ slaves. society does not frown upon the man who sits with his mulatto child upon his knee, whist its mother stands a slave behind his chair. in many respects, as robert s. levine writes in his historical back- ground to brown’s text, “mastery afforded southern slave owners an ex- ploitative sexual power, and their practice of treating some of their slaves as concubines became an unspoken part of southern white culture” . by exploiting the vulnerability of enslaved women and girls, white male slave owners were able to both satisfy their “boundless licentiousness” and increase their own wealth by encouraging and personally participat- ing in the production of enslaved offspring. king, “prematurely knowing of evil things,” . ibid. harriet martineau, “morals of slavery” in

than protecting women, there were no laws in place to prevent white men from abusing their slaves. en- slaved women were considered overtly sexual by nature; regardless of age, they “were assumed to be experienced without concern about whether or not they were sexually active” . even the most horrific cas- es of sexual violence committed against innocent young girls were ig- nored solely on the basis of race. for example, in , james keyton was indicted by a grand jury in tennessee for “violently feloniously and unlawfully” raping an enslaved girl named beck who was under ten- years-old at the time. witnesses testified “that keyton did “forcefully” and “wickedly” come to “carnally know and abuse” beck “against her will”. unfortunately for beck, she was not to receive justice. while the grand jury had believed her case was worthy of an indictment, jurors ul- timately rendered a verdict of “not guilty in manner and form as charged in the indictment”. the grand jury felt that they had no other choice as a result of an statute which set down that: “if any slave or free person of color, shall be guilty of the crime of rape, upon the person of any white female child, under the age of ten years, he shall suffer death for such offense, upon conviction,” meaning that because beck was not white and her assailant was not black, she was not entitled to either pro- tections or recompense under the law. keeping these ideas in mind, the sexual exploitation and victimization of enslaved women and girls is a topic that found its way into many an- ti-slavery works of the eighteenth and nineteenth century, both fictional and non-fictional in nature. william wells brown founded the basis of his literary work, clotel or the president’s daughter, on this culture of exploitation and assault. first and foremost, the title of his work refers specifically to the rumored sexual relationship between president thom- as jefferson and sally hemings, one of his female slaves. historically, “there is considerable evidence that they had seven children together, and that jefferson gave special privileges to both hemings and their chil- dren”. brown choose to root his narrative in the sexual exploitation of the fictional enslaved woman currer, an obvious stand in for hemings, by president thomas jefferson in order to represent that this attitude and corresponding belief system could be traced to the highest echelons of american society – the president of the united states. if such a man, a king, “prematurely knowing of evil things,” . ibid., . ibid., . ibid. ibid. levine, “thomas jefferson and sally hemings,” . denial of consent: the modern heir of sexual violence within slavery man who preached of liberty and equality, was susceptible to such base desires than it is not surprising his example was followed by other slave owners throughout the country. the heroines at the center of brown’s text each face sexual exploita- tion and victimization within slavery at the hands of white men. the experiences of the matriarch, currer, as has already been elaborated, allude to the sexual relationship between thomas jefferson and sally hemings. that being said, the experiences of her eldest daughter and tit- ular character, clotel, represent the southern practice, especially found in new orleans, of pairing mulatto, mixed race, girls with wealthy white gentlemen. these young girls were specifically “brought up by their mothers to be what they [had] been; the mistresses of white gentle- men” . as harriet martineau further elaborates: every young man early selects one, and establishes her in one of those pretty and peculiar houses, whole rows of which may be seen in the remparts. the connection now and then lasts for life: usually for several years. in the latter case, when the time comes for the gentleman to take a white wife, the dread- ful news reaches his quadroon partner, either by a letter entitling her to call the house and furniture her own, or by the newspaper which announces his marriage. in clotel’s case, she believes her relationship with horatio green to be one founded upon love and mutual affection. green, in essence, seduces clotel with notions of love and fidelity. however, after green purchases clotel, she has no legal protections within their self-labeled marriage. while he promises that, after purchasing her, he will “make her mis- tress of her own dwelling” , as his property, she is completely under his power. when green eventually does abandon his vows to clotel for the advantages of a politically and socially motivated marriage, she refuses to continue their sexual relationship. this choice, she admits: “would no doubt expose her to his wrath, and probably cause her to be sold”. her fears are eventually realized when she is sold first, as a maid and, second, for other, more unseemly, purposes. as brown explains: “most quadroon women who are taken to the lower countries to be sold are either pur- chased by gentlemen for their own use, or sold for waiting-maids”. in martineau, “morals of slavery,” . ibid. brown, clotel, . ibid., . ibid., . michaela kleppinger the end, after first escaping her master and then being recaptured trying to reclaim her daughter mary, clotel chooses death over a lifetime of enslavement and further abuse at the hands of white men. while her sister, althesa, is arguably the most fortunate of brown’s cast of enslaved women, her two daughters are not as lucky. after the death of althesa and her husband, it is discovered that she was once a slave, invalidat- ing their marriage. as a result, their two daughters are sold. her eldest daughter ellen makes the same choice as clotel upon realizing “for what purpose she had been bought”. ellen’s younger sister jane is similarly purchased by a wealthy young man to be sexually exploited. she, ulti- mately, dies of a broken heart. in the end, after living lives characterized by exploitation, manipulation, and assault, each of brown’s heroines dies a tragic death. turning from fictional examples of the sexual exploitation and victimization of enslaved women and girls, while frederick douglass, in his narrative of the life of frederick douglass, avoids overtly discuss- ing the practice, there is one scene which stands out as a particularly gut-wrenching example – the whipping of aunt hester. douglass’ aunt hester was a uniquely beautiful woman. as he describes: “she was a woman of noble form, and of graceful proportions, having few equals, and few superiors, in personal appearance, among the colored or white women of our neighborhood”. as a result, she unfortunately catches the attentions of their master. douglass is rather demure in elaborating upon these attentions, simply leaving his readers to intuit the facts for themselves: “why my master was so careful of her, may be safely left to conjecture”. however, it may be safely assumed that their master was sexually assaulting or harassing hester is some form, especially consid- ering how closely he policed her independent sexuality: he had ordered her not to go out evenings, and warned her that she must never let him catch her in company with a young man, who was paying at- tention to her belonging to colonel lloyd. the young man’s name was ned roberts, generally called lloyd’s ned. hester does not heed these commands and continues to visit lloyd’s ned. as a result, as douglass details, one night she “happened to be ab- sent when [their] master desired her presence” and was found with ibid., . frederick douglass, narrative of the life of frederick douglass: an american slave, written by himself (new york: simon & schuster paperbacks, ): . ibid. ibid. ibid. denial of consent: the modern heir of sexual violence within slavery ned. douglass and hester’s master is enraged, both that he was not able to satisfy his sexual desires when he wished, and because hester had the nerve to seek her own satisfaction elsewhere. what follows is a brutal scourging that is both difficult to read and difficult to imagine a woman enduring: before he commenced whipping aunt hester, he took her into the kitch- en, and stripped her from neck to waist, leaving her neck, shoulders, and back, entirely naked. he then told her to cross her hands, calling her at the same time a d–d b–h. after crossing her hands, he tied them with a strong rope, and led her to a stood under a large hook in the joist, put in for the purpose. he made her get upon the stool, and tied her hands to the hook. she now stood fair for his infernal purpose. her arms were stretched up at their full length, so that she stood upon the ends of her toes. he then said to her, “now, you d–d b–h. i’ll learn you how to disobey my orders!” and after rolling up his sleeves, he commended to lay on the heavy cowskin, and soon the warm, red blood (amid heart-rending shrieks from her, and horrid oaths from him) came dripping to the floor. this is hester’s punishment for failing to bend to her master’s every whim; for failing to allow herself to be unconditionally sexually available to him. what this scene contradicts, more than any other concept, is the absolutely ludicrous notion that enslaved women and girls were capable of consenting to sexual relationships with their masters within the in- stitution of slavery. they had no options. they had no rights or liberties. a man could rape them or brutalize them. as long as the man was their master, it was his choice – not theirs. in her fictionalized retelling of her own experiences within the institution of slavery, incidents in the life of a slave girl, through the pseudonym linda, harriet jacobs details the sexual harassment she faced at the hands of her owner, dr. flint. upon turning fifteen her life dramatically shifts as she is thrust from the meager protections of girl- hood into the almost complete vulnerability of enslaved womanhood. the slave girl is abandoned by society – abandoned by mankind – to “be- come prematurely knowing of evil things”. the slave girl quickly learns “to tremble when she hears her master’s footfall”; she quickly learns “she is no longer a child”. in jacobs’ case, flint begins to “whisper foul words in [her] ear” and fill her “young mind with unclean images” in ibid., – . harriet jacobs, “incidents in the life of a slave girl,” in the classic slave narra- tives, ed. henry louis gates, jr (new york: signet classics, ): . ibid. michaela kleppinger order to “corrupt the pure principles [her] grandmother had instilled” . jacobs does her best to combat flint’s advances; however, as she reminds her readers, as his slave she is particularly vulnerable: but he was my master. i was compelled to live under the same roof with him – where i saw a man forty years my senior daily violate the most sacred commandments of nature. he told me i was his property; that i must be subject to his will in all things. my soul revolted against the mean tyranny. but where could i turn for protection? no matter whether the slave girl be as black as ebony or as fair as her mistress. in either case, there is no shadow of law to protect her from insult, from violence, or even from death; all these inflicted by fiends who bear the shape of men. in an effort to break jacobs’ resolve, using diction reminiscent of brown’s horatio green, flint makes promises to “cherish” jacobs’ and treat her as a “lady”. he even begins building jacobs’ her own house “in a secluded place” outside of town for their sole use and privacy – effectively prom- ising to make her his mistress. jacobs escapes the clutches of dr. flint, but not before being forced by circumstance into a less detestable form of sexual exploitation at the hand of mr. sands, which produces two children. emancipation and the sedimentation of stereotypes of black female sexuality following the course of history, emancipation would, unfortunately, not save black women and girls from sexual exploitation and victimization at the hands of white men. as estelle b. freedman writes in her chap- ter “african americans redefine sexual violence” from redefining rape: “from the day they were liberated to the present time, prepossessing young colored girls have been considered the rightful prey of white gen- tlemen in the south, and they have been protected neither by public sen- timent nor by law”. as one southern african american woman wrote to a white magazine in the s, “few colored girls reach the age of sixteen without receiving advances” . while no longer subject to the same power dynamics present within the institution of slavery, with the emergence of jim crow era segregation and discrimination, black wom- jacobs, “incidents in the life of a slave girl,” . ibid. ibid., . ibid., . freedman, “african americans redefine sexual violence,” . ibid., . denial of consent: the modern heir of sexual violence within slavery en and girls continued to be left unprotected by the law and society. one educator, anna julia cooper, expressed her concerns in , by describ- ing “the promising “colored girls of the south” who lived “in the midst of pitfalls and snares, waylaid by the lower classes of white men”. espe- cially in the reconstruction years immediately following the civil war, “white men raped black women with impunity” as a means of revenge for their perceived losses. furthermore, young black girls continued to be sexually exploited within the homes of wealthy white men. activist fannie barrier williams reported receiving frantic letters from mothers desperately asking for help for their daughters “to save them from going into the homes of the south as servants, as there is nothing to save them from dishonor and degradation” . as in slavery, black women and girls continued to be targets of sexual predators. potentially the most dangerous concept that has emerged out of this history and culture of sexual exploitation and victimization is confused notions of consent. there have been considerable efforts in the post-slav- ery years to label enslaved women who had sexual relationships with their owners as mistresses. this is dangerous, simply put, because words have meaning – labels have meaning. the fifth edition of webster’s colle- giate dictionary defines a “mistress” as “a woman paramour” . the more contemporary dictionary.com similarly defines a “mistress” as “a wom- an who has a continuing, extramarital sexual relationship with one man, especially a man who, in return for an exclusive and continuing liaison, provides her with financial support” . the problem with applying this label to enslaved women is that it implies mutual consent, despite the reality that any form of sexual contact within the institution of slavery was, if not assault, at least extremely exploitative. even brown, who ef- fectively and emotionally described the sexual exploitation and victimi- zation of enslaved women and girls in clotel, voiced similar sentiments within the novel: reader, when you take into consideration the fact, that amongst the slave population no safeguard is thrown around virtue, and no inducement held out to slave women to be chaste, you will not be surprised when we tell you that immorality and vice pervade the cities of the southern states in a man- ner unknown in the cities and towns of the northern states. indeed most of ibid. ibid. freedman, “african americans redefine sexual violence,” . “mistress,” webster’s collegiate dictionary, th edition ( ): . “mistress,” dictionary.com. michaela kleppinger the slave women have no higher aspirations than that of becoming the finely dressed mistress of some white man. disproportionate power dynamics between an enslaved woman and her master rendered her incapable of consenting to a sexual relationship – any other perspective undermines the horrific reality of the trauma and abuse these women and girls experienced. looking back, specially at the case of thomas jefferson and sally hemings, many scholars and historians have desired to label hemings as jefferson’s mistress – to impose some sort of consensual and affectionate relationship upon them. however, as mentioned previously, what these romantic notions fail to consider is that, within bondage, a woman was incapable of consenting to any sort of sexual contact with the man who owned her. furthermore, regardless of the idealistic image of thomas jefferson that has been propagated throughout the united states with- in classrooms and the media at large, he unquestionably took advan- tage and exploited the young woman under his power. thomas jefferson first met sally hemings, the enslaved daughter of his father-in-law and half-sister of his deceased wife, in , when “she was fourteen and he was forty-four” . hemings was, at the time, undoubtably, still a child. calling enslaved women mistresses completely erases the reality of their victimization at the hands of white men. this victim blaming, while a rather contemporary term, is not a con- temporary idea. within the institution of slavery as well as the years following their emancipation, african american women and girls were blamed for their own violation, both by their communities and society at large. looking to mrs. flint as an example, she tells a young enslaved girl, on the brink of death following the birth of a child fathered by dr. flint: “you suffer, do you?” […] i’m glad of it. you deserve it all, and more too”. when the girl’s mother expresses a wish for her daughter and grandchild to “soon be in heaven,” mrs. flint cruelly asserts that “there is no such place for the like of her and her bastard”. mrs. flint blames this young girl for her own violation at the hands of dr. flint— as if the child courted and encouraged the predator’s attentions. there were some individuals who even believed, like mrs. flint, most notably frances kellor, that “enslavement made all black women less capable of leading moral, respectable lives”. kellor further blamed african amer- brown, clotel, – . levine, “thomas jefferson and sally hemings,” . jacobs,

justice, and denial of consent: the modern heir of sexual violence within slavery ican women and girls, “without considering that women might resist harassment and rape” by stating that “negro women yield to white men quite as readily as in slavery” . it is from these roots of coercion and sexual assault that the myth of the inherently sexually immoral black female was born. instead of making an attempt to counteract these vicious stereotypes, following emancipation and into the twentieth century, many individu- als among the african american community demonized and condemned lower class black women whom they judged to be immoral. many mid- dle-class black women “who claimed their rights to sexual respectabil- ity often contrasted their own morality with that of lower class black women”. these women suggested that the “sexual behavior” of low- er-class black women “discredited the race” . in harriet jacob’s nar- rative, while her children ultimately serve as her motivation to escape from bondage, in freedom their existence labels her as sexually immoral and promiscuous – as was considered the case for many single moth- ers. when she is honest regarding the choices she was forced to make as a slave, including the conception of her children, the minister mr. durham cautions her: “your straightforward answers do you credit; but don’t answer everybody so openly. it might give some heartless people a pretext for treating you with contempt”. even prominent leaders and intellectuals, like w.e.b. du bois, “emphasized that single black women in the city jeopardized the stability of black families”. using rhetoric and ideals very similar to those espoused by actors of rape culture today, many individuals, both from within and outside of the black community, “sought to assist and instruct young black women” in how to avoid becoming victims instead of condemning their victimizers. women like jacobs, women who has escaped slavery but not without certain scars, were judged and blamed for the paths their lives had taken – for the con- sequences of their own exploitation and victimization. as a result, in contrast to the mainstream african american commu- nity, there were some outspoken activists, mainly black women, who desired to expose the hypocrisy of white male views of female virtue and chastity and combat the stereotypes that demonized black women and girls. for example, ida b. wells pointedly criticized the “southern reform in new york, – (chapel hill: university of north carolina press, ), . hicks, “i want to save these girls,” . freedman, “african americans redefine sexual violence,” . ibid., . jacobs, “incidents in the life of a slave girl,” . hicks, “i want to save these girls,” . ibid. michaela kleppinger sensitivity to women’s honor” , that led to the lynching of scores of black men as a result of accusations of raping white women, while they par- ticipated and continued to participate in the violation of black women and girls without consequences. wells acutely wrote: “virtue knows no color line, and the chivalry which depends upon complexion of skin and texture of hair can command no honest respect”. wells, and her fellow african american female activists, understood the danger that notions of black female sexual immorality could have as “reformers dedicated to protecting young women from moral dangers often found themselves characterized by black men and white society as immoral, or at least morally questionable” . wells, and other women like her, understood that all black women felt the consequences of “blanket accusations of immorality” that denied the accomplishments of, in her words: “moth- ers, wives and maidens who have attained a true, noble, and refining womanhood” . harriet jacobs was one of these mothers who had over- come adversity and societal prejudice in order to provide for her chil- dren. as she ends her narrative: “reader, my story ends with freedom; not in the usual way, with marriage. i and my children are now free!” . jacobs is acutely aware that she will always be condemned and excluded by large segments of her own community. regardless of her accomplish- ments, she will always be judged for her particular path to motherhood and the circumstances that surrounded this path. these stereotypes of black female immorality, like the jezebel, sought to undermine the credibility of black women and girls. the jezebel being “one of the most overtly sexual images of african american women to have emerged […] is often depicted as a “mulatto” woman with light skin and long hair” and “perceived as seductive, manipulative, and una- ble to control her sexual drives” . in order to combat these stereotypes, wells and other activists “employed a range of arguments to defend the respectability of black women, including an insistence that white men should be held accountable for interracial assaults” as they “agreed that white men deserved most of the blame for the sexual degradation of women of their race”. however, despite their best efforts, there con- tinued to be “cases of white men who got away with the rape of black freedman, “african americans redefine sexual violence,” . ibid. hicks, “i want to save these girls,” . freedman, “african americans redefine sexual violence,” – . jacobs, “incidents in the life of a slave girl,” . tiffany g. townsend,

“african americans redefine sexual violence,” . ibid., . denial of consent: the modern heir of sexual violence within slavery women and girls”. at best these men received “light sentences” . in most cases, the perpetrator never made it to trial as grand juries refused “to indict white men for rape”. the complete lack of consequences faced by white men for raping black women and girls, and the labeling of them as inherently sexually experienced, effectively made them the perfect victims. denial of consent as manifest today looking at the treatment faced by black women and girls today, espe- cially those enmeshed in disadvantaged communities who have been virtually abandoned by the police, it is careless to ignore the reality of their risk for sexual victimization. in the lives of these women and girls “the threat of sexual violence [is] a common theme”. as one adolescent black girl named britney explained in jody miller’s sociological study getting played: african american girls urban inequality and gendered violence: we face…a lot of stuff. males, if you don’t want to give it up they’ll probably try to take it. if you walking by yourself and in the dark they’ll probably ap- proach you and want to, you know what i’m saying, do something with you. that’s why you don’t never walk by yourself after dark. approximately “ % of girls […] reported having been forced to have sexual intercourse at some time in their lives” – “african americans girls report[ing] higher rates of involuntary first intercourse than their european and latina counterparts” . as previously alluded, the great- est threat these stereotypes continue to pose is that they have “made black women more vulnerable to sexual assault”. by discounting and discrediting their word. rape culture is a concept typically roughly de- fined as “a set of values and beliefs that promote an environment condu- cive to rape”. these labels and stereotypes of black female immorality, that originated within the institution of slavery, are interwoven with rape culture; they have created “an environment conducive to rape” by ibid. ibid. ibid. jody miller, getting played: african american girls urban

away with raping a woman who society already considers sexually deviant and desiring of such ill-treatment. furthermore, in a society that does not place value in the va- lidity of their word, these women and girls have been forced to remain silent. they have been forbidden to voice their traumas – forbidden to name their abusers – “lest any discussion of sexuality contribute to neg- ative depictions of their morality”. in more contemporary examples, the words of desiree washington and anita hill were both disregarded when they dared to name their assailants. instead of coming to the aid of these women, the african american community and greater society defended mike tyson and clarence thomas. tyson’s supporters claimed, “that he was being “railroaded” by a vengeful woman and a biased judi- cial system” and that her charges “were detrimental to african ameri- cans in general, and black men in particular”. the religious leaders of the national baptists convention usa even asked their congregations “to ignore washington’s allegations” . these actions and the reactions of african americans to the assault of a woman from their own commu- nity, highlight specifically how “the marginalization of african american women” has eliminated “their right to protection from sexual assault” and effectively “erased their ability to refuse consent”. as in the institu- tion of slavery, african american women and girls continue to be left to fend for themselves against a world populated by predators. conclusion in his introduction discussing thomas jefferson and sally hemings, rob- ert levine posed the question: “what sort of culture celebrated human equality and then countenanced slavery and the practice of rape?” . while levine is specially referring to the united states of the revolu- tionary era, his question still has resonance for the current state of the country. segments of white society have, since emancipation, unceasing- ly called for an end to the discussion of the institution of slavery. they believe, or would like to convince others to believe, that the institution hicks, “i want to save these girls,” . townsend, neilands, thomas, and

continue to live with the consequences of slavery – to live with the consequences of the exploita- tion and victimization of their ancestors at the hands of white men. while simply acknowledging and recognizing the weight of these evils will not erase the dangers these women and girls face, it is a place to start. bibliography brown, william wells. clotel; or, the president’s daughter: a

and chemokine receptor-binding sites. additionally, by incorporating t - and -helix- resistance mutations into individual env protomers, we were able to interrogate exposure of discrete gp n-hr and c-hr domains. our data indicate that a single cd binding to an env trimer is sufficient to promote fusion. moreover, the first cd binding event appeared to expose only one of three possible binding sites for each fusion inhibitor, suggesting an asymmetric transition into the phi. this asymmetry was significantly more pronounced in the gp n-hr region compared to the gp c-hr region. these results can be used to explain the multiphasic titration of mutant env homotrimers that naturally form asymmetric n-hr domain structures. taken together, these data suggest that the native state-to-phi transition of env occurs in a multistep (asymmetric) fashion. -pos board b evolution of hiv- resistance to a cholesterol-linked d-peptide fusion inhibitor amanda e. siglin , nicholas francis , michael s. kay , micheal j. root . thomas jefferson university, philadelphia, pa, usa, university of utah, salt lake city, ut, usa. during hiv- entry, the n-hr and c-hr regions of the gp viral glycoprotein associate to form a trimer-of-hairpins critical for membrane fusion. the n-hr region contains a highly conserved hydrophobic pocket that is the target for a multivalent, d-peptide fusion inhibitor, pie -trimer. recently, a modified form of this inhibitor with a conjugated cholesterol (chol-pie -trimer) was shown to possess up to -fold increased potency, presumably due to mem- brane targeting. here, we determined the resistance profile of chol-pie - trimer starting from either inhibitor-naı̈ve or pie -trimer-resistant hiv- (nl - strain). viral propagation in increasing inhibitor concentrations pro- duced hiv- populations with - to -fold reduced sensitivity chol- pie -trimer. these viruses were also resistant to the parental, unconjugated inhibitor pie -trimer. using hiv- fusion inhibitors di-c and -helix, we were able to interrogate the effect of escape mutations on the exposure of the gp n-hr and c-hr regions, respectively. resistance to chol-pie - trimer resulted in a slight decrease in the temporal window of n-hr exposure, regardless of the starting viral population. exposure of the c-hr region was unchanged for resistant viruses generated from the inhibitor-naı̈ve viral pool. by contrast, the temporal window of c-hr exposure was significantly increased (> -fold) for resistant viruses that were generated from the pie -trimer-resistant viral pool. efforts to identify the mechanisms of chol- pie -trimer resistance and the decoupling of n-hr and c-hr exposure are underway. -pos board b fusogenic activity of the hiv- gp mper-tmd region: mechanism and targeting by immunogens and inhibitors jose l. nieva , beatriz apellaniz , carmen domene , nerea huarte , eneko largo . biophysics unit (csic-upv/ehu) and dept. of biochemistry, university of the basque country (upv/ehu), bilbao, spain, chemistry research laboratory, university of oxford, oxford, united kingdom. fusion of the viral envelope with the cell membrane marks the beginning of the hiv- replicative cycle. this event is targeted by inhibitors currently in clinical use and by preventive vaccines under development. antibodies e and e bind to the gp membrane proximal external region (mper)- transmembrane domain (tmd) junction and block fusion. these antibodies display the broadest viral neutralization known to date, which underscores the conservation and functionality of the mper-tmd region. in recent work, we have described that peptides representing this region have potent membrane-destabilizing effects. here, based on the outcome of vesicle assays, atomic force microscopy studies and molecular dynamics simulations, we propose a mechanism for the involvement of the mper-tmd region in hiv- fusion. in addition, we provide evidence that underpins the poten- tial use of its activity as a new target for inhibitor and immunogen development. -pos board b studies on the membrane-active behavior of outer membrane vesicles from a gram negative bacterium william bartos, rensa chen, donald y. kobayashi, paul r. meers. rutgers, the state university of new jersey, new brunswick, nj, usa. gram-negative bacteria are known to produce small ~ - nm vesicles by ‘‘blebbing’’ of their outer membranes. these outer membrane vesicles (omv) have been implicated in activities such as transmission of virulence fac- tors, horizontal gene transfer and development of biofilms. in this investigation, the interactions of omv from lysobacter enzymogenes (strain c ) with other membranes have been monitored using fluorescent assays for association and/or fusion. defined composition large unilamellar vesicles labeled with the fluorescence resonance energy transfer (fret) pair , -dipalmitoyl-sn- glycero- -phosphoethanolamine-n-( -nitro- - , -benzoxadiazol- -yl) (nbd- pe) and , -dipalmitoyl-sn-glycero- -phosphoethanolamine-n-(lissamine rho- damine b sulfonyl) (rh-pe) were incubated with isolated omv to observe the interaction via the fret ratio of donor/acceptor. omv substantially increased this ratio over the course of about an hour (t / ~ - min.) at �c, when added directly to vesicles comprising disordered or fluid lipids, such as -palmitoyl- -oleoyl-sn-glycero- -phospho-( ’-rac-glycerol) (popg), -pal- mitoyl- -oleoyl-sn-glycero- -phosphoethanolamine (pope) or -palmitoyl- - oleoyl-sn-glycero- -phosphocholine (popc). this apparent fusion was much more limited or absent with liquid ordered membranes of , -dipalmitoyl-sn- glycero- -phosphocholine/cholesterol (dppc/chol). in the case of popg/ pope / vesicles, apparent fusion was also confirmed by testing vesicles with exclusively inner monolayer fluorescent probes to diminish any fluores- cence changes from external interactions of outer monolayer fluorophores. when the omv were labeled with the fluorophore , -dioctadecyl- , , , - tetramethylindocarbocyanine, and incubated with a natural host, yeast cells (strain s ), association and/or fusion was observed by co-sedimentation of the omv label with yeast cells. these studies may help to elucidate the mech- anism of natural host-pathogen interactions and define the lipid specificity for hiv fusion peptide perturbs membrane structure in a cholesterol dependent fashion cd binding induces an asymmetric transition of hiv- env from its native conformation into the prehairpin intermediate state evolution of hiv- resistance to a cholesterol-linked d-peptide fusion inhibitor fusogenic activity of the hiv- gp mper-tmd region: mechanism and targeting by immunogens and inhibitors studies on the membrane-active behavior of outer membrane vesicles from a gram negative bacterium corr insights®: custom acetabular cages offer stable fixation and improved hip scores for revision tha with severe bone defects corr insights : custom acetabular cages offer stable fixation and improved hip scores for revision tha with severe bone defects thomas jefferson blumenfeld md where are we now? t he ideal reconstructive method for the severely deficient acetabulum in revision tha remains unsolved. severe acetabular deficiencies may be evaluated by the paprosky et al. [ ] grading system from which both the anticipated bony defects and the reconstruction needs may be identified. fortunately, the incidence of severe acetabular deficiency is low, with a report from the mayo clinic finding that paprosky iiib defects occurred in only . % of hips ( / ) undergoing revision acetabular surgery at that ter- tiarycarecenterbetween – [ ]. most acetabular reconstructions are performed with a large hemispherical shell with a survivorship range of % to % at mid- to long-term followup [ ]. for acetabuli with greater bony loss, porous metal augments may be added, allowing the creation of a bony and metal concavity supportive of a hemispherical shell. as the defect worsens, more-elaborate options come into the picture, perhaps including custom acetabular cages (or triflange cups), reconstruction cages, cup-cage constructs, or cup-cup constructs. surgeons must recognize the high surgical complexity when contemplat- ing using one of these approaches, as complications can be severe, and unrecognized or untreated pelvic dis- continuities can result in a high risk of failure. during more than a -year period, the authors of the current study reported the surgical treatment of patients (all with type iiib defects, four with a pelvic discontinuity) who underwent acetabular reconstruction using a grit- blasted titanium custom cage. at a mean followup of months (range, months to months) in patients only one cage was felt to be possibly loose, and the authors reported the appearance of particulate allograft incorporation in of patients. one important caveat of this study is that this was the first revision surgery for all but one patient. we can compare the results in this series to other reports about severe acetabular defects, which used other approaches, namely reconstruction cages, or custom triflange cups. in a single-surgeon series, reconstruction cages failed in % of reconstructions at mean . -year followup, with the highest failure rates occurring in hips with american academy of orthopaedic surgeons (aaos) type this corr insights is a commentary on the article ‘‘custom acetabular cages offer stable fixation and improved hip scores for revision tha with severe bone defects’’ by li and colleagues available at: doi: . /s - - - . the author certifies that he, or any member of his immediate family, has no funding or commercial associations (eg, consultancies, stock ownership, equity interest, patent/ licensing arrangements, etc.) that might pose a conflict of interest in connection with the submitted article. all icmje conflict of interest forms for authors and clinical orthopaedics and related research editors and board members are on file with the publication and can be viewed on request. the opinions expressed are those of the writers, and do not reflect the opinion or policy of corr or the association of bone and joint surgeons . this corr insights comment refers to the article available at doi: . /s - - - . t. j. blumenfeld md (&) sutter medical center, k street, suite , sacramento, ca , usa e-mail: tblumenfeld @gmail.com corr insights published online: december � the association of bone and joint surgeons clin orthop relat res ( ) : – / doi . /s - - - clinical orthopaedics and related research® a publication of the association of bone and joint surgeons® http://dx.doi.org/ . /s - - - http://dx.doi.org/ . /s - - - http://dx.doi.org/ . /s - - - http://crossmark.crossref.org/dialog/?doi= . /s - - - &domain=pdf http://crossmark.crossref.org/dialog/?doi= . /s - - - &domain=pdf iv (pelvic discontinuity) defects [ ]. in these reconstructions, even with the use of structural allograft, three cages loosened, two flange fractured, and a pelvic dissociation remained in two reconstructions. similar results were shown by perka et al. [ ] who reported that three of revisions for grade iiib defects failed at a mean of . years. where do we need to go? these failures, in my opinion, are not secondary to the concept of spanning a deficient acetabulum with a large metal frame, but due to the loss of either ischial fixation, or malleable flange fracture, both possibly related to the use of materials of inadequate strength. material issues and fixation can be addressed by the use of a cus- tom triflange. christie et al. [ ] reported on acetabular reconstruc- tions performed with a custom triflange component of which involved an aaos type iv defect. at mid-term followup % ( / ) of the reconstructions showed healing of the pelvic discontinuity. similar results have been reported [ ] with those authors suggesting posterior column plating of the discontinuity. therefore, both the current report, and prior data, would suggest three key elements for success: material rigidity, fixation stability, and creation of a custom implant that attempts to reproduce the joint center. whether filling the acetabular defect with metal or as in the current report, allografting of the defects, will lead to improved long- evity, remains unanswered. these unique reconstruction situa- tionspointtothreeresearchneeds:( )to confirm that we are comparing apples to apples in terms of the defects being studied, ( ) to identify the implant most likely to result in a durable long-term reconstruction for type iiia and iiib defects, and ( ) to try to lower the cost when a custom implant is needed. how do we get there? regarding the first unmet need, while the paprosky classification system has concrete radiographically identifiable guidelines which allow discrimination between a type iia/b and iiia/b defect, decisions are subjective. the preoperatively identified paprosky clasification has been shown to corelate to the intraoperativley identified acetabular defect volume [ ]. a prospective study that included the preoperative paprosky defect classifi- cation, the intraoperative bony defects identified, and the implant(s) used, might allow further refinement of the classification system. although the data on the use of one or more augments and a porous metal acetabular component appear extremely promising [ ], in order to satisfy the second unmet need, we need long-term data (a minimum of years) before concluding that the majority of type iiia defects can and should be man- aged in this fashion. finally, what to do for the most-sev- ere defects remains unsolved and it remains up to the discretion of the sur- geon whether to use a reconstruction cage, the custom implant as described by li et al., or a custom triflange cup. the apparent reconstructive answer at this time is that the implant needs to be structurally rigid, and obtain bony fixa- tion. one may consider these custom implants to be analogous to ‘‘orphan drugs,’’ in that these devices are rela- tively rarely used and so there is little incentive for implant vendors to keep the prices down. the general cost from the time of ct scanning to custom implant creation is more than usd . therefore, it seems rational to try to create an off-the-shelf reconstruction cagethatincorporatesthe benefitsshown with the use of custom implants, without the need for component fabrication for individual patients. references . berry dj, lewallen dg, hanssen ad, cabanela me. pelvic discontinuity in revision total hip arthroplasty. j bone joint surg am. ; : – . blumenfeld clinical orthopaedics and related research corr insights . blumenfeld, tj. implant choices, technique, and results in revision acetabular surgery: a review. hip int. ; : – . . christie mj, barrington sa, brinson mf, ruhling me, deboer dk. bridg- ing massive acetabular defects with the triflange cup: - to - year results. clin orthop relat res. ; : – . . fernandez-fairen m, murcia a, blanco a, merono a, murcia jr a, ballester j. revision of failed total hip arthroplasty acetabular cups to porous tantalum components: a -year fol- low-up study. j arthroplasty. ; : – . . goodman s, saastamoinen h, nadav s, gross a. complications of iliois- chial reconstruction rings in revision total hip arthroplasty. j arthroplasty. ; : – . . holt ge, dennis da. use of custom triflanged acetabular components in revision total hip arthroplasty. clin orthop relat res. ; : – . . paprosky wg, perona pg, lawrence jm. acetabular defect classification and surgical reconstruction in revision arthroplasty. a -year follow-up eval- uation. j arthroplasty. ; : – . . perka c, ludwig r. reconstruction of segmental defects during revision procedures of the acetabulum with the burch-schneider anti-protrusio cage. j arthroplasty. ; : – . . yu r, hofstaetter jg, sullivan t, costi k, howie dw, solomon lb. validity and reliability of the paprosky acetabular defect classification. clin orthop relat res. ; : – . volume , number , march corr insights corr insights corr insightsreg: custom acetabular cages offer stable fixation and improved hip scores for revision tha with severe bone defects where are we now?

non-permissive in gvhd; or non-permissive in hvg direction. objective: to determine whether tce classification is associated with hsct outcomes. the outcomes considered in this analysis are failure to engraft, acute gvhd, chronic gvhd, and overall survival. methods: we analyzed unrelated donor ($ / allele matches at a, b, c, drb ) allogeneic transplants performed in our center be- tween - . hla-dpb mismatches were assessed using both tce and tce versions of the algorithm. recursive parti- tioning analysis with a log-rank splitting method was used to catego- rize tce variables into groups that best predict each outcome. cox proportional hazards analysis was used to identify prognostic factors for each outcome. results: graft failure was significantly highest among recipient with permissive dpb mismatches (ahr . , % ci . - . , p . ) compared to recipients of zero mismatched, gvhd non-per- missive, and hvg nonpermissive dpb mismatched donors. acute gvhd was significantly higher in all dpb mismatches regardless of tce classification (ahr . , % ci . - . , p . ) com- pared zero dpb mismatch. there was no significant association be- tween tce classification and chronic gvhd, or overall survival. poster session i s conclusion: our results indicate an increased risk of acute gvhd in association with dpb mismatch regardless of the tce classifica- tion. tce classification did not correlate with any transplant out- come considered in our cohort. this analysis does not support the clinical relevance of ranking dpb mismatches based on the tce algorithm. a scoring system predicting outcome after unrelated donor stem cell transplantation in primary refractory acute mye- loid leukemia craddock, c.f. , labopin, m. , schmid, c. , mohty, m. , rocha, v. queen elizabeth hospital, birmingham, united kingdom;

( ) integrate a realistic simulation model for hands-on, rapid cycle de- liberate practice (rcdp) with em residents; and ( ) compare the efficacy of our task trainer with similar hys- terotomy models for resident learners. rcdp represents a conceptual model for skill acquisition that provides for timely and focused education [ ]. simulation training of high-stakes, low-frequency procedures, combined with rcdp, offers a ripe opportunity for the development of “muscle memory” and enhanced confidence during highly stressful conditions [ ]. through the use of a sur- vey previously cited in the simulation literature [ ], the authors aimed to specifically measure the following: preference of instructional delivery with regard to hys- terotomy training, appreciation for human anatomic representation, applicability to clinical practice, comfort with performing resuscitative hysterotomy, and familiar- ity with the procedure. these were each captured through items on the survey. method for this training program innovation, two identical high-fidelity, tissue-based task-trainer models were con- structed and tested on a convenience sample of em residents at the thomas jefferson university, a -year em residency program in philadelphia, pa, usa. partici- pant breakdown included five post-graduate-year (pgy)- residents, six pgy- residents, and three pgy- residents. the training for simulation delivery for em residents took place at a monthly journal club literature review session, which was held in a classroom on the medical school campus. two identical task trainers were implemented to allow for simultaneous procedural learning among the learners for the training program. simulated human placentas, bladders, and uteri were constructed through the use of porcine skin, porcine stomach, and a squid mantle, re- spectively, which were secured in place with nylon su- tures. the amniotic sac was created through the use of a transparent plastic bag that contained a gaumard s articulating newborn and was filled with warm water (i.e., the amniotic fluid) through a foley catheter. each task trainer model was placed into a gaumard s childbirth simulator with an overlying porcine belly to simulate the gravid abdomen. once the aforementioned models were created, they were mounted on a plastic dolly cart that allowed for ease of transport across pre-clinical environments. each model required less than h for assembly (fig. ) and cost $ . to construct (excluding expired hospital supplies and existing gaumard s task trainers, provided in kind by the in- stitutional simulation center) (table ). a detailed step-by-step construction guide for the biosimulated re- suscitative hysterotomy can be found in additional file : appendix . emergent hysterotomy was first demonstrated by the content expert (i.e., em faculty facilitator) and followed by immediate hands-on deliberate practice. errors in technique were immediately corrected at each step, and the preceding steps were reviewed prior to continuing the procedure. learners were cycled twice through both simulators with rapid cycle feedback, utilizing the micro-debriefing format (i.e., feedback was delivered im- mediately as each step in the procedure was performed) [ ]. residents who were not performing the hysterotomy watched their peers, and questions were encouraged. residents were divided into pairs, and each pair had the opportunity to perform the procedure. the biosimula- tion models were reset between procedures via reim- plantation of the fetus model with placenta inside new plastic bags with all previous lacerations repaired with nylon suture. formal feedback on the learners’ self-reported confidence and satisfaction levels was soli- cited at the end of the workshop through the use of sur- vey that was previously used specifically for low-fidelity resuscitative hysterotomy [ ]. quantitative evaluation of the simulated training session was extracted through a -item questionnaire using a -point likert-type scale (i.e., from , strongly disagree, to , strongly agree). item scores were added for a cumulative total score, with a possible maximum total score of and a minimum total score of . this study was exempt from review by the thomas jefferson university institutional review board (irb), as the resident workshop was part of the em residency cur- riculum. participants provided verbal consent for their anonymous responses to be collected. results the response rate from resident participants was %. responses were overwhelmingly positive [ .

( . )]. at the conclusion of the course, all participants rated their inter- est in the course as high [ . ( . )]. ratings for enthusi- asm post-course were not significantly higher than pre-course (t = . × − , p = . ). all participants ( %) recommended the training session be available for future emergency medicine residents. qualitative feedback from self-written responses highlighted the learners’ appreciation for hands-on prac- tice ( % of resident responses), practice-changing man- agement towards resuscitative hysterotomy ( % of resident responses), and the realistic nature of the tissue-based simulation task trainer ( % of resident re- sponses). areas for improvement included ( ) additional models to allow for repeated practice (i.e., more than two times), ( ) ongoing cardiopulmonary resuscitation (cpr) during the procedure to further increase realism, and ( ) visual printout of the procedural steps with the model. discussion creating an inexpensive, lifelike, simulation training model with tactile realism was a primary goal of this innovative workshop. previously attempted models have relied on ex- pensive simulation equipment as the basis for their models. one model in the literature [ ] is based on the gaumard noelle unit, which costs $ at the time of this paper alone (http://www.gaumard.com/s ). by con- trast, the simulation pelvis used in this study was much cheaper ($ ), including the simulation baby (http:// www.gaumard.com/s ), and could be used several times for multiple learners. though the equipment could theor- etically be borrowed from a university simulation center, not all residency programs have access to expensive high-realism simulation models or access to a simulation center for this purpose. even without the simulated pelvis, this model could easily have been placed in a simple plas- tic wash basin commonly found in the ed, and the pro- cedure could still have been performed in its entirety. this in turn supports the portability of the model to many dif- ferent clinical and pre-clinical environments for training. in addition, the entire cost of the disposable materials in this model was $ . for two high-fidelity tissue models. though this at a glance is more expensive than the materials used in prior attempts ($ for seven models [ ] or $ – for one model [ ]), the subtle benefit of incorporating animal tissue models is the abil- ity to suture the tissue together post procedure and re-arranging the tissue for the next participant, allowing for the creation of multiple fresh models to allow partic- ipants experience the procedure in an rcdp style repeti- tion several times. in a technological age where anatomy labs are becoming more expensive to upkeep and digital applications are taking over standard pedagogy, tactile learning and experience are somewhat lost. as a further attribute, a tissue-based model allows the learner to feel the different layers of anatomy during incision, a sensa- tion that cannot be reproduced with commercial and/or gelatin products. as a final benefit of the present model, the creation of two models took the study investigators less than h each to construct from start to finish. one model de- scribed in the literature [ ] requires latex to dry over- night as a single step, in addition to having gelatin set for h at a time. other published studies [ , ] do not specify a construction time. the study investigators propose that the quick production and rapid portability across different learning spaces make this an efficacious model for learning resuscitative hysterotomy. when considering other cesarean simulators currently available on the market or those that allow for such modifications (table ), some important key issues arise. though the other models listed are serviceable for edu- cating general procedure and anatomy, the disadvantage lies in their higher cost and expenditure. in our opinion, only one model is debatably comparable in realism, but is extreme in cost (operative experience’s c-celia - ob- stetric simulator for fetal extractions at cesarean deliv- eries, ranging from $ , to $ , ). combining bio tissue or moulage materials with these simulators can re- sult in damage to electronic components, some which may be difficult to sterilize. the current chosen model was easy to outfit with the aforementioned tissue and decontaminate after the session, making it more effica- cious in cost, durability, and realism. the model’s structural advantages were mirrored by the overwhelmingly positive feedback by the em learner-participants in familiarizing and preparing them for future performance. this study employed the same assessment scale as previously described by sampson et al.’s [ ] low-fidelity resuscitative hysterotomy model, with resounding success. the cumulative satisfaction scores between our model and sampson’s model were . and . , respectively. the data from both studies show a preference of hands-on simulation above trad- itional lectures and reading alone, the improvement in procedural competency, and usefulness for future emer- gency department shifts. the use of animal tissue also offers both cost-effective and high-fidelity advantage in lau et al. advances in simulation ( ) : page of http://www.gaumard.com/s http://www.gaumard.com/s http://www.gaumard.com/s fig. evaluation of simulation model. all survey questions ( – ) were adapted from sampson et al.’s [ ] survey analysis of a low-fidelity resuscitative hysterotomy model, using a -point likert-type scale lau et al. advances in simulation ( ) : page of preparing participants for the techniques necessary in dissecting through actual tissue layers. furthermore, the rcdp style training was well-received by all participants by allowing them to improve upon their previous mis- takes in real time, be offered feedback on their technical skills, and review critical actions before progression. this simulation can be combined with cpr as described by nadir et al. to further increase the fidelity [ ]. with respect to the accreditation council for gradu- ate medical education (acgme) milestones for resident competency, this high-realism task trainer, if fully imple- mented with the use of high-fidelity simulation tech- niques (i.e., incorporating confederate actors or environmental props), has the potential to enhance fu- ture patient care with respect to the following: emer- gency stabilization (patient care ), diagnosis (patient care ), general approach to procedures (patient care ), medical knowledge, and team management (inter- personal and communication skills ) [ ]. residents are challenged to recognize the critical situation of a pregnant mother in extremis; understand the indications to perform the resuscitative hysterotomy; communicate with staff and preceptors about their intent, equipment, and personnel required; and physically perform the pro- cedure in a safe clinical environment. the challenges of this simulation reflect sufficiently the skills needed, stress level, and mental capacity required to manage crit- ical illness under duress. limitations the study was limited in power due to being at a single center and including a small sample size of em learners. despite using an assessment from a previous study, we were unable to determine a statistical significance due to the small sample sizes. though the results promisingly suggest that a tactile, tissue-based, rcdp simulation can stimulate learner knowledge and enhance practice pat- terns, more study is needed to adequately demonstrate that this particular format is superior to traditional simulation-based learning and journal club experiences. conclusion resuscitative hysterotomy is a high-stakes, low-frequency procedure that demands provider practice and confidence. review of procedural steps, indications, and materials needed is imperative to the success of this procedure in pregnant patients in extremis. our hybrid, tissue-based hysterotomy model shows promise in adding the next level of realism for deliberate procedural practice while of- fering additional utility in cost, reproducibility, and port- ability to learners of various abilities. future studies can explore learning benefit differences between using cheaper table currently commercially available obstetrical simulation models/task trainers/simulators gaumard advanced childbirth simulator cs “ob susie” $ https://www.gaumard.com/s simulaids obstetrical manikin $ https://www.simulaids.com/product/ -

]. hfov provides a small tidal volume ( - ml/kg) in high-frequency ( - hz) to optimize alveolar gas exchange while eliminating peak pressure and full pulmonary expansion in the setting of restricted compliance. our current venovenous extracorporeal membrane oxygenation (vv ecmo) practice includes the use of a single, dual-lumen avalon® cannula (maquet, rastatt, germany) placed to the right internal jugular vein, although with this positioning, the applied intrathoracic pressure created by hfov may compete with the ecmo flow. herein, we report a case of blood shunting observed in an avalon cannula and treated with an increase of ecmo flow. case presentation a -year-old female (weight: . kg; height: cm) with ards secondary to aspiration pneumonia was placed on vv ecmo using a single fr avalon cannula to the right internal jugular vein. her peak airway pressure was cm h o, even with low tidal volume ( ml) ventilation, and eventually, she was unable to ventilate safely due to decompensated compliance. hfov with a frequency of bpm and hz was introduced on ecmo day # to decrease the risk of volutrauma while also preventing atelectasis from hypoventilation. her mean airway pressure (mpaw) became . cm h o with hfov, which comparatively had been cm h o on the conventional ventilator. at the time of transition to hfov, her settings were: ecmo flow . l/min, sweep l/min, fio %, with ventilator fio %. approximately two hours later, the patient desaturated requiring fio % on both the ecmo and hfov to maintain an o saturation (sao ) of %, although the ecmo flow was maintained at . l/min. these same settings were continued before a flash of bright red, oxygenated blood was noted flowing into the venous return lumen of the avalon cannula which synchronized with each beat of the oscillator (video ). video : avalon cannula flash of bright red, oxygenated blood is noted flowing into the outflow lumen in the patient from the avalon extracorporeal membrane oxygenation (ecmo) cannula (yellow arrow), suggesting recirculation of oxygenated and unoxygenated blood. view video here: https://youtu.be/ziueeo fhnc mcdermott et al. cureus ( ): e . doi . /cureus. of the correct placement of the avalon catheter and endotracheal tube were confirmed by chest x- ray, and an echocardiogram further confirmed the cannula position (the tip in the inferior vena cava and the access lumen facing the tricuspid valve), as well as ruled out a patent foramen ovale or an atrial septal defect. inter-atrial shunting within the avalon cannula was diagnosed, and the ecmo flow was increased above . l/min to overcome the additional resistance. this provided a resolution of the retrograde shunt. despite all efforts, this patient, unfortunately, expired due to multi-organ failure. her family elected to withdraw care after a total of days on ecmo and four days on hfov. discussion it was hypothesized that the pulses of applied intrathoracic pressure created by the hfov contrasted with the systemic low pressures of the venous system where the avalon cannula lies, causing the intra-atrial shunt. as described by sklar et al., elevation of the right atrial (ra) and pulmonary artery pressures (pap) were observed during hfov [ ]. in an ecmo circuit, negative pressure (approximately - mmhg assuming an ecmo flow of . l/min with an avalon cannula size fr) was maintained through the return lumen while positive pressure (approximately mmhg assuming an ecmo flow of . l/min with an avalon cannula size fr) is applied by the centrifugal pump into the access lumen. using the avalon cannula allows the circuit to suction de-oxygenated blood from the superior vena cava (svc) and inferior vena cava (ivc) and instill oxygenated blood toward the tricuspid valve simultaneously creating a vv ecmo system through only one insertion site. with augmented external pressure from hfov, the pap suddenly elevates and causes the avalon catheter’s oxygenated out-flows to face an increased resistance which can dilate the ra when sustained. thus, turbulent flow within the ra may cause shunting that can exacerbate hypoxia as oxygenated blood recirculates towards the venous return lumen of the avalon cannula. in our patient, we believe the intra-atrial recirculation became noticeable due to a deepened contrast between the venous and arterial blood as the fio from ecmo was raised to %. to decrease pap, deep sedation and paralysis may be necessary, though these were already being applied in this case. furthermore, inhaled vasodilators, such as nitric oxide or epoprostenol, are an additional adjunct; however, we have found this therapy to be impractical during hfov use. instead, we increased the vv ecmo flow above . l/min, which was able to unload the ra by overcoming the raised pap (access lumen approximately mmhg) and optimizing suction from the svc and ivc (return lumen approximately - mmhg), resolving the intra-atrial shunt. while maintaining a high ecmo flow is possible, this requires additional patient monitoring and care due to a concomitant heightened risk of mechanical hemolysis. for this reason, we determined that, while interesting to note, intra-atrial shunt presence is clinically relevant to the patient primarily when contributing to decompensated hypoxia refractory to typical management strategies (namely, increasing fio ). therefore, we elected to continue this patient’s ecmo management per usual protocols by setting the ecmo flow based on the body surface area (bsa) and symptom severity (with the goal to maintain the sao above % and a normal ph) rather than on the mere presence or visibility of a shunt. upon review of this case, we are reminded that the mpaw on hfov is higher than that of lung protective ventilation via a conventional ventilator. while this comparative increase is expected due to the need for accommodation of the loss of dynamic peep, perhaps the mpaw could have been decreased in a setting of resolved hypoxia. as suggested in sklar et al., elevated mpaw itself may contribute to volutrauma, potentially explaining the failure of hfov to be proven beneficial thus far [ ]. it should be considered that while lung protective ventilation has been shown to improve ards outcomes during conventional ventilation, standard practice settings are applied during hfov to maintain an adequate gas exchange. facilitation of lung protective ventilation while on hfov could be possible with the concurrent mcdermott et al. cureus ( ): e . doi . /cureus. of use of hfov and high-flow ecmo, however. while we were unable to attempt this method for our patient due to sustained hypoxia, it may simply be that stricter parameters and a decreased mpaw are required to create a mortality benefit, as well as limit intra-atrial shunting, as we described. further research is required to evaluate the outcomes of severe ards patients on minimized, lung protective hfov settings. it is known that hfov may promote hemodynamic instability and other sequelae, though once identified, mitigation of these problems may be possible. regardless, present information suggests that hfov worsens ards mortality for mild-moderate cases and remains unproven as a benefit for severe cases. its use continues to be up for debate; therefore, it is not recommended as an initial therapy. however, hfov can be a useful adjunct in patients who continue to fail after conventional ventilator management is maximized with concurrent use of ecmo, paralysis, prone therapy, and nebulized epoprostenol. the expansion of care modalities is critical to continue advancing the ability for high-risk patients to recover from severe episodes of ards. conclusions by maintaining safer pulmonary pressures with hfov, while improving the exchange of gasses via ecmo, lungs impaired by ards that have failed conventional ventilation may be further allowed to heal. in the event that a clinically relevant intra-atrial shunt occurs during the concurrent use of hfov with vv ecmo via an avalon cannula, it is likely that an increase in the ecmo flow rate will decrease the shunting effect. additional information disclosures human subjects: consent was obtained by all participants in this study. thomas jefferson university institutional review board issued approval d. . we are submitting a case report which is waived from consent form. all ecmo patient registry at thomas jefferson university was approved by thomas jefferson university irb file number # d.

ma, usa. emerging evidence shows the importance of genes controlling mitochondrial fusion in physiology and their deregulation in neurodegenerative and metabolic disorders. however, apart from djm, the biophysical properties of the fusion- competent mitochondria remain elusive. to evaluate the conditions of contact formation and fusion, we used organelle-targeted fluorescent proteins, includ- ing photoactivatable gfp, which allow tracking of individual mitochondria. in h c cells, almost every mitochondrion is aligned with microtubules that pro- vide the primary tracks for mitochondrial movement. our results show that ~ % of fusion events involve moving mitochondria. however, fusion occurs irrespective of mitochondrial speed. furthermore, ~ % of fusion events in- volve the tip portion of the mitochondrion, whereas only ~ % of these events involve organelle side. nocodazol, a microtubule disrupting agent that inhibits mitochondrial movements decreases the fusion frequency and changes mito- chondrial fusion sites. strikingly, - % of the physical contacts between ad- jacent mitochondria did not result in fusion events. to evaluate whether the fu- sion efficacy depends on the spacing between the outer and inner mitochondrial membranes we used drugs that alter the matrix volume. valinomycin, a k þ ion- ophore that induces matrix swelling evoked a decrease in mitochondrial motil- ity leading to fewer contacts among mitochondria but the number of fusion events was maintained, indicating an increase in fusion efficacy. this change occurred at a low valinomycin concentration ( . nm) that did not affect djm or opa cleavage. nigericin ( . mm), a k þ /h þ ionophore that induces shrinkage of the matrix elicited fusion inhibition and mitochondrial aggrega- tion. importantly, no motility inhibition or opa cleavage occurred at the same time and the djm was increased. these results suggest that mitochon- drial fusion is facilitated by mitochondrial motility, the key determinant of the inter-mitochondrial encounter numbers and preferentially involves the front-tip of the moving organelle. in addition, fusion efficacy depends on the mitochondrial matrix volume. -pos mitochondrial fusion dynamics in human skeletal muscle-derived cells veronica eisner, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. mitochondria have a fundamental role in both muscle physiology and pathol- ogy. mitochondrial fusion and fission are important for energy metabolism, calcium homeostasis and cell death. however, the mechanisms underlying mitochondrial dynamics are poorly understood, especially in physiological models such as skeletal muscle. here we evaluated mitochondrial fusion dy- namics in human skeletal muscle cells (husmc). skeletal muscle satellite cells were isolated from human muscle biopsies and were maintained and dif- ferentiated in cell culture. mitochondrial fusion events were evaluated by con- focal imaging of cells expressing mitochondria matrix targeted dsred and matrix targeted or outer mitochondrial membrane (omm) targeted photoacti- vatable-gfp. when we tagged the mitochondria in ~ % of total cellular area with photoactivated-gfp, we found those mitochondria undergoing matrix fusion with a frequency of . . events/min/cell (n= ). among the fusion events, % led to complete fusion and only % was followed by separation at the apparent fusion site within to seconds. both complete and transient fusion events resulted mostly from longitudinal mergers, involving end to end interaction or from mergers of adjacent mitochondria in side to side orien- tation. furthermore, we found that omm and matrix fusion are sequential and separable steps, displaying . seconds gap (n= ). finally, we evaluated the mitochondrial fusion dynamics in husmc derived from both normal and malignant hyperthermia susceptible individuals. at resting state, no significant differences were found in the number of events or in their characteristics. thus, mitochondrial fusion commonly occurs in husmc, and enables mixing of both soluble and integral membrane factors. this process would help to maintain the stability of mitochondrial metabolism. the relatively low frequency of the tran- sient fusion is probably due to the parallel organization of the cytoskeletal tracks for mitochondria and to the limited mitochondrial motility. -pos imaging interorganelle contacts and local calcium dynamics at the er-mitochondrial interface györgy csordás , péter várnai , tünde golenár , swati roy ,

development, bethesda, md, usa. the local coupling between er and mitochondria is essential for proper cell function. a main role of the er-mitochondrial junctions is to provide a local calcium signaling domain that is important both for keeping energy production in line with demand and for the control of apoptotic mechanisms. so far it has not been possible to visualize the tiny er-mitochondrial contact points in living cells or to monitor the localized [ca þ] changes in the narrow space between er and mitochondria ([ca þ]er-mt). here, we exploited rapamycin-mediated heterodimerization of fkbp and frb domains of fluorescent protein constructs respectively targeted to the outer mitochondrial membrane and the er as drug-inducible inter-organelle linkers to identify er-mitochondrial contacts and to measure the [ca þ ]er-mt. high- resolution fluorescence imaging and d reconstruction revealed rapamycin-in- duced clustering of the er-targeted fluorescent linker-half to the contact areas with the mitochondria without major changes in the spatial arrangement of the er. essentially all mitochondria displayed contacts with the er in both rbl- h and h c cells. plasma membrane-mitochondrial contacts were less frequent with er stacks being inserted between the two organelles. single mitochondria display discrete patches of er contacts as well as continuous as- sociations. cytoplasmic and mitochondrial matrix [ca þ] showed robust er-mitochondrial ca þ transfer with considerable heterogeneity even among adjacent mitochondria. pericam-containing linkers revealed ip -induced [ca þ ]er-mt signals that were resistant to buffering bulk cytosolic [ca þ ]c in- creases and exceeded um. the largest [ca þ ]er-mt signals did not occur at the tightest associations, indicating space requirements for the ca þ transfer machinery and functional diversity among er-mitochondrial junctions. these studies provide direct evidence for the existence of high ca þ microdo- mains between the er and mitochondria in living cells, and open new possibil- ities to probe the functional importance of this specialized compartment. -pos dependence of er-mitochondria

pa, usa, university of rochester medical center, rochester, ny, usa. ip receptors (ip rs) release ca þ from the er, which is locally relayed to the mitochondria to control several aspects of mitochondrial function. recent stud- ies have suggested that type ip rs (ip r ) are particularly important for me- diating the ca þ transfer at the er-mitochondrial interface. we set out to sys- tematically evaluate the respective role of each ip r isoform in chicken dt cell lines that express only one ip r isoform (double-knockout, dko , dko and dko ) or provide a null-background (triple-knockout, tko) for analysis of mammalian ip rs and their mutants. simultaneous imaging of cytoplasmic and mitochondrial matrix [ca þ] ([ca þ]c and [ca þ]m) was performed in either permeabilized cells chal- lenged with ip or in muscarinic receptor overexpressing intact cells stimulated with carbachol (cch), an ip -linked agonist. saturating ip evoked complete discharge of er calcium and resulted in comparable [ca þ]m increases in each dko. furthermore, the cch-induced [ca þ]c spike was closely followed by a [ca þ]m rise in each dko. when tko cells were rescued with rat ip r or ip r , the latter mediated a larger [ca þ]c transient but the [ca þ]m increases were very similar for both isoforms. the relationship between the [ca þ]c peak and the corresponding [ca þ]m response was also very similar for ip r and ip r . to assess the impact of the release kinetic through ip r in the mitochondrial ca þ transfer we used two point mutants of the ip r , which display either enhanced inhibition by ca þ (d n) or are relatively insensitive to ca þ inhibition (d n). d n showed dampened [ca þ]m signal and [ca þ]m vs. [ca þ]c relationship, whereas d n displayed a steeper [ca þ]m vs. [ca þ]c relationship than the wild type ip r . thus, each ip r isoform can support local er-mitochondrial ca þ transfer and their competence to activate mitochondrial ca þ uptake depends on their deactiva- tion kinetic. biophysical properties of mitochondria undergoing fusion mitochondrial fusion dynamics in human skeletal muscle-derived cells imaging interorganelle contacts

wc a ae, uk this presentation analyzes specialised mental health courts (mhcs), as one solution to the long-standing, growing challenge of dealing fairly and justly with persons with mental illness (pmis) coming before the criminal justice system, from a human rights (hr) perspective. mhcs have garnered professional and political support in north america. redefining their primary purpose from the determination of fault and the imposition of punish- ment to the provision of treatment and the enhancement of well-being, to date little consideration has been given to whether the costs of mhcs in terms of de-individual- ised justice are worth their benefits. as harris points out, 'sometimes wise policies and practices can have unin- tended side effects'. and as thomas jefferson reminds us, 'the price of liberty is eternal vigilance'. thus, addressing the hr implications of mhcs should rank highly on its advocates' agendas. potential hr concerns, arising from mhcs and relating to pmis essential dignity rights as well as their rights to non-degrading treatment, autonomy, pri- vacy, due process and non-discrimination, will be assessed. like other writers, the presenter urges that only through respecting pmis' rights to services and fulfilling society's duty to provide same, and not through mhcs, will pmis be afforded the full rights that democratic states ought to provide their citizens. the manner in which mdos are managed (or not) by the multiple services and systems they typically encounter creates a broad measure of dissatisfaction that goes beyond any single jurisdiction or country. moreover, the sufficient issue overlaps and fundamental commonalities in approaches to the prob- lems faced by mdos provide a general societal and judi- cial context for an analysis of mhcs and a related hr discussion, notwithstanding the presenter references the provisions of the european convention on human rights (echr) ( ) for her hr analysis. from wpa thematic

[jefferson to thomas mann randolph, jr., august ; boyd , jefferson entered the college of william and mary in . there as a student of william small, professor of natural philosophy and mathematics, jefferson was exposed to newton’s fluents and fluxions. he would later use that knowledge to solve the problem of finding the best form of a body to raise a sod and reverse it after the share has cut under it. in recognition of his achievements in designing a mouldboard of least resistance, he was elected an honorary member of the english board of agriculture in and awarded a gold medal by the agricultural society of paris in . with reference to small’s influence, jefferson wrote: it was my great good fortune, and what probably fixed the destinies of my life. that dr. william small of scotland, was then professor of mathematics, a man profound in most of the useful branches of science, with a happy talent of communication, correct and gentlemanly manners, and an enlarged and liberal mind. he, most happily for me, became soon attached to me, and made me his daily companion when not engaged in school; and from his conversa- tion got my first view of the expansion of science, and from the system of things in which we are placed. [autobiography; lipscomb & bergh , jefferson was only , and had not entered maury’s school yet, when his father died. after more than years had passed, jefferson reflected on his education and referred to small as being . . to me as a father. to his enlightened mind and affectionate guidance, i am indebted for everything. [jefferson to louis hue girardin, january ; lipscomb & bergh , jefferson’s breadth as well as depth in mathematics and astronomy can be estimated by noting the scientific books that he either owned or suggested to others. he assembled three libraries during his lifetime. the first consisted of about volumes, including inherited from his father, which were destroyed by fire a.t shadwell in . the second library consisted of approximately works, and was sold to congress in to replace the original library of con- gress, lost in the burning of the capitol by the british during the war of . the third library consisted of about works originally willed to the university of virginia, but eventually sold at auction by the executors of his estate in to meet outstanding debts. approximately of the books sold to congress dealt with either mathematics or astronomy, and from the many references to these works found in his correspondence, we can infer that he had more than just a cursory knowledge of their contents [ ]. jefferson’s avid interest and fondness for mathematics and astronomy pervaded his program of study for his grandson, thomas jefferson randolph. the program included instruction in surveying and celestial navigation. “trigonometry prob- lems” may relate to the part of this program carried out at poplar forest, the estate in bedford county, virginia, inherited by jefferson upon the death of his father-in-law, john wayles. jefferson approached the task zealously and wrote: hm note i have been for some time rubbing up my mathematics from the rust contracted by f i f t y years’ pursuits of a different kind. and thanks to the good foundation laid at college by my old master and friend small, i am doing it with a delight and success beyond my expectation. [jefferson to the reverend james madison, december : lipscomb & bergh , using letters that jefferson wrote from poplar forest to his daughter, martha jefferson randolph [ and february ; betts & bear , - , we can establish that he spent the month of february at that location. in , he referred to the latitude determinations at least twice in his correspondence. in the summer, he wrote: while here, and much confined to this house by my rheumatism, i have amused myself with calculating the hour lines of a horizontal dial for the latitude of this place which i find to be ” ’ ”. the calculations are for every five minutes of time, and are always exact to within less than half a second of a degree. [jefferson to the reverend charles clay, august : lipscomb & bergh , later that winter, he wrote: i had observed the eclipse of september th with a view to calculate from it myself, the longitude of monticello; but other occupations had prevented it before my journey. the elaborate paper of mr. lambert shows me it would have been a more difficult undertaking than i had foreseen, and that probably i should have foundered in it. i have no telescope equal to the observations of the eclipses of jupiter’s satellites, but as soon as i can fit up a room to fix up my instruments in, i propose to amuse myself with further essays of multiplied repeti- tions and less laborious calculations. i have a fine theodolite and equatorial both by ramsden, a hadley’s circle of borda, fine meridian and horizon as you know. once ascertaining the dip of my horizon, i can use the circle as at sea, without an artificial horizon. do you think of ever giving us a second edition of your map? i f you do i may be able to furnish you with some latitudes. i have a pocket sextant of miraculous accuracy, considering its microscopic graduation. with this i have ascertained the latitude of poplar forest, (say new london) by multiplied observations, and lately that of willis mountains by observations of my own, repeated by my grandson, whom i am carrying on in his different studies. [jefferson to the reverend james madison, december ; lipscomb & bergh , - the calculations in “trigonometry problems” correspond to those of douwes’ method of calculating latitude using double solar altitudes. the method was very popular among british navigators in the late th century because cornelius douwes ( - ), an examiner of sea officers and pilots for the college of admiralty at amsterdam, included tables containing logarithms for the sine, cose- cant, and versed sine of an angle in temporal measure of hours and minutes rather than in angular measure of degrees and minutes, reducing immensely the calcula- tions involved. by the time jefferson used the method, it had been further simpli- fied by nevil maskelyne ( - l), fifth astronomer royal at greenwich, in his requisite tables, where the logarithms of the appropriate functions significant for io-set intervals of time were included, thus avoiding some interpolation necessi- tated by douwes’ original tables. jefferson owned two copies of the edition of maskelyne’s tables requisite and was able to benefit from the modifications. note hm besides the simplicity of the mathematical computations involved, perhaps the overriding reason that jefferson used douwes’ method was that the interval of time between the two observations need only be measured with a common watch. “trigonometry problems” is two pages long and is horizontally partitioned into zones (fig. ). the first zone contains data relating to five solar altitude obser- vations taken on february , . the next zones contain the calculations for seven separate latitude determinations using a distinct pair of the solar altitudes in each zone. the th zone contains data on the solar altitude reading taken on february and six observations taken on february . data on solar altitude readings taken on february appear in the th zone. the latitude of poplar forest is ” ’ ” north of the equator and the deviations in the true latitude and the latitudes calculated by jefferson in the th and th zones are most likely the result of his relaxing the conditions which are necessary fig. . thomas jefferson, “trigonometry problems.” reprinted with permission from edgehill- randolph collection, thomas jefferson papers (fc- ). university of virginia library. hm note for the method to be at all accurate. for not only must a reasonably close estimate be given as a fu-st approximation to the true latitude (jefferson used ” ’), but the two solar altitude observations must be taken less than one hour apart, with one of the readings being an hour or less from noon. in addition, the actual method is a recursive one. hence, after a second approximation to the latitude has been calculated, the process should be repeated using the second approximation as the assumed latitude together with the original two solar altitude observations. thus, the process must be repeated several times if there is to be any consistent accu- racy in the determination of the latitude using douwes’ method. to those who are unfamiliar with douwes’ method and the mathematics in- volved, the following illustration is offered as a key to understanding the computa- tions that jefferson dealt with in calculating the latitude of poplar forest. the first four columns of data in the first zone contain, respectively, the time of the obser- vations, the observed altitude of the sun, the true altitude of the sun (the observed altitude corrected for dip or the height of the observer above sea level, the refrac- tion of the atmosphere, and the time of day), and finally the sine of the true altitude of the sun. for example, the data for the first observation of february was taken at h ” ”, the observed altitude of the sun at that time was ” ’ ”, the true altitude of the sun was ” ’ ”, and the sine of the true altitude was given by . . in the fifth column, we find the declination of the sun on february , ( ” ’ ”), the logarithm of the secant of the declination ( . ), the first approximation to the latitude ( ” ’), the logarithm of the secant of the assumed latitude ( . ), and the log ratio, or sum of the mantis- sas of the two preceding logarithms ( . ). then in the second zone, with reference to the first solar altitude reading taken on february , jefferson sub- tracted the sine of the lesser altitude ( . ) from the sine of the greater altitude ( . ) obtaining . , and in the last column recorded . (which should read . ), the common logarithm of . the figure . , appear- ing just below . in the last column, refers to the logarithm of the cosecant of half the elapsed time between the two observations ( m s), after the time has been converted into angular measurement, using the standard convention of ”/ hr. here jefferson made a minor error in interpolating, for the figure should actually be . . after adding these two logarithms to the log ratio to obtain . , and looking up its antilogarithm ( h m s), which is referred to as the middle time, jefferson subtracted the half time from the middle time to obtain h m s, which is the time from true noon when the greater solar altitude observa- tion was taken. the next figure ( . ), in the last column of the second zone, is the logarithm of lh ” ”, and is referred to as log rising or logarithm of the versed sine less half. subtracting the log ratio from the log rising, jefferson then obtained . , the antilogarithm of which divided by , is . . the addition of . to the sine of the greater altitude yields . . finally, by taking the arcsine of . we obtain the second approximation to the latitude of poplar forest, namely ” ’. a recursive algebraic formulation of douwes’ method is given by note hm sin(a) = sin(az) - sin(ar) cos(xjcos( )sill(t/ ) sin( + - hi+,) = sin(c) + cos(ai)cos(i )sit (b/ ), where aj is the true altitude of the sun at time tj, j = , , tr < tz? t = t - t, b = ia - (t/ )/ c = max(ar, ai) is the declination of the sun a; is the ith approximation to the latitude, i = , , . . . [cotter . in “trigonometry problems,” we are afforded a rare glimpse of thomas jeffer- son doing practical mathematics. not only are we able to follow his arithmetic manipulations, but we can also sense a feeling of accomplishment with the results, as jefferson himself must have done on those chilly winter days in . acknowledgment the author thanks the university of virginia library for permission to reproduce jefferson’s “trig- onometry problems.” notes . an informative account of jefferson’s utilitarian view of mathematics as well as some of his contributions to mathematics education can be found in [smith . an extensive list of bibliographic material relating to jefferson’s scientific contributions can be found in [arret & putney . . see [sowerby - for an annotated list of books that jefferson sold to congress, [tanner for a list of books willed to the university of virginia, and [poor for a list of books sold at auction. the books listed in peter jefferson’s will can be found in the virginia magazine of history and biography ( - ), . . in , as part of the governor’s summer program in science and mathematics for the state of rhode island, i had the opportunity to supervise a group of talented high school juniors and use douwes’ method to determine the latitude of providence. besides being a good exercise in practical mathematics the lesson opened up avenues of discussion regarding jefferson as an amateur mathemati- cian and scientist, the popularity of douwes’ method, and the mathematics and history of the period. the students found the assignment to be both mathematically and historically rewarding. it not only emphasized a branch of mathematics which has been sorely neglected in the high school curriculum, but also brought to light yet another

criminality first emerged when american visited italy during the period of the early american republic ( - ). the paper shows how italian criminality was first developed and transmitted through the travel writings of american grand tourists, such as thomas jefferson’s secretary william short, the novelist washington irving, and the historian theodore dwight. this study shows how these notions of italian criminality, originating before the civil war ( - ), shaped the way italian immigrants were received upon arrival in the u.s. during the period of their mass migration, between the s and . in that year, the united states introduced a system of quotas based on national origin that “closed the door” to italians and other immigrants. tracing the genealogy of deep-rooted american stereotypes about italian criminality back to their th century origin, this paper shows the trans-national features upon which italians were categorized within the ethno-racial hierarchies that structured late th and early th century american society. keywords: transnationalism; grand tourism; immigration; criminality; ethno-racial formation. ost americans are proud of their country’s identity as a “nation of immigrants.” many would also like to believe that the united states has always been an “asylum of liberty,” offering refuge to the world’s “tired, poor huddled masses, yearning to breathe free.” yet, for most of its history, the united states has not been a particularly welcoming place for the foreign-born. according to the standards established by the naturalization expressed in many ways, by many speakers and authors over the years, the idea of the united states is a “nation of nations” was, perhaps most famously, expressed by poet walt whitman in the preface to his volume, leaves of grass. the publication of u.s. senator john f. kennedy’s book a nation of immigrants in ushered in an era in which the moniker has become a common reference. the idea of the united states as an “asylum of liberty” can be traced to thomas paine’s popular tract common sense ( ), written during the american war for independence ( - ). these lines are taken from emma lazarus, sonnet “the new colossus” ( ). in , lazarus’s iconic poem was inscribed on the inside of the pedestal of the statue of liberty. m | darkest italy revisited jam it! no. may | nationalism: hyper and post act of , the first law passed by congress under the constitution regulating the status of foreign-born people inside the u.s., only “free, white, male aliens of good character” who had resided in the u.s. for at least two years were eligible to become american citizens. persons who did not meet these criteria – for example, native americans, people of african descent, foreign-born women and all other “non-whites” – were classified either as property, dependents, or permanent aliens. reflecting this tacit cultural consensus, as early as benjamin franklin defended north americans’ application of the racial category of “whiteness” exclusively to persons of anglo-saxon descent in his treatise observations concerning the increase of mankind. in this tract, franklin advised his fellow englishmen to make every effort to exclude “all blacks and tawneys” from settling in north america. his list of undesirables also included “swarthy,” “non-white” european groups like “the spaniards, italians, french, russians and swedes,” and even most german populations as well. in his view, the only purely white populations were “the saxons, who with the english, make the principal body of white people on the face of the earth” (franklin , - ). the naturalization act of , reflecting the social and cultural hierarchies developed during the british colonial era, adopted the notions of “whiteness” and “good character” to identify qualities understood to be the unique provenance of people of protestant “anglo- saxon” (e.g. british/northern european) heritage. with only a few minor alterations, these criteria structured the relationship between race, character, immigration, and citizenship until the american civil war ( - ). until the eve of the american civil war, franklin’s ethno-centric sense of “true whiteness” as a quality exclusive to people of anglo- saxon heritage set the pace for the interpretive paradigms of race, national origin and character through which u.s. immigration and naturalization policy took shape. so long as the critical mass of “free, white” people seeking to naturalize as u.s. citizens hailed from the british isles, saxony and other parts of “pure white” northern europe, the formulation contained in the law helped maintain the cultural homogeneity of the predominantly protestant, anglo-american population. however, during the middle decades of the th century, the united states’ color-coded immigration system faced a crisis when a rising tide of immigration from the catholic and jewish parts of europe began to arrive en masse in anthony antonucci | the united states. the arrival of these new immigrant groups meant that the legal definition of what it meant to be “free and white” could no longer stand as easy proxy for people of protestant, anglo-saxon descent. the first waves of non-anglo-saxon newcomers of european descent arrived in the s and s and consisted of catholics from ireland and the french speaking parts of eastern canada seeking opportunity in the rapidly industrializing sectors of the u.s. economy. by the s, the largest immigrant groups to the u.s. included italians, greeks, lithuanians, poles, czechs, and russian jews, among others. to many native-born citizens, the mass arrival of “swarthy” catholic and jewish foreigners from southern and eastern europe threatened the stability and homogeneity of the anglo-american way of life. fearing that mass immigration would carry old world poverty, crime, and social divisions to american shores, anglo-saxon nativists mobilized a national movement for immigration restriction. by , the advocates for immigration restriction succeeded in redefining the criteria that determined naturalization. overturning the naturalization act, the national origins act of (also known as the johnson-reed act) restricted immigration visas to two percent of the total number of people of each nationality already in the united states as of . in effect, the reed- johnson act closed immigration for non-anglo-saxon european nationalities, as well as for all asians. consequently, from until the overhaul of reed-johnson with the hart- celler immigration act in , immigration and naturalization in the united states were regulated by national origin quotas, rather than by qualifications based explicitly on race and moral character. nevertheless, in the views of many u.s. citizens and government officials these categories and qualifications remained intimately intertwined. at the root of the divisive debates that have shaped u.s. immigration policy are fundamental nativism is an umbrella term encompassing the waves of social and political movements aimed at protecting the interests of native-born anglo-saxons above those of immigrants who did not hail from northern europe or the british isles. as the harvard-trained lawyer prescott hall, co-founder of the immigration restriction league, quipped in , “do we want this country to be peopled by british, german and scandinavian stock—historically free, energetic, progressive, or by slav, latin, and asiatic races—historically downtrodden, atavistic and stagnant?” (hall , ). see also higham, . specifically, the johnson-reed act granted people immigrating from countries of northern and western europe more than , visas each year; by contrast, southern and eastern european countries received just , visas and all the countries of asia and africa combined were given , . the law did not apply to persons emigrating from other nations in the western hemisphere, such as mexico and other parts of latin america and the caribbean. | darkest italy revisited jam it! no. may | nationalism: hyper and post questions about citizenship and national belonging: who and what is an american? who is qualified to become an american? to date, much of the scholarly literature examining this topic has focused on how variable constructions of race and ethnicity have been applied to successive waves of foreign groups, and how these various ethno-racial formations have shaped immigrants’ prospects for full participation in american life. inspired by critical perspectives developed by scholars such as david roediger and other contributors to the interdisciplinary field of “whiteness studies,” in the s and early s a new generation of immigration historians took up the task of uncovering what matthew frye jacobson describes in whiteness of a different color ( ) as the relationship between “european immigrants and the alchemy of race.” demonstrating the fluidity of late th and th century racial categories, jacobson’s influential study demonstrates that many of the people americans now widely regard as belonging to white ethnic groups were previously perceived as racial “others” understood to be “less than fully white.” as evidence, jacobson reported that, during the late th and th centuries, self- identified american anglo-saxons classified immigrants from the catholic and jewish parts of europe, such as irish and italians, as belonging to inferior “celtic,” “latin” or “mediterranean” races. jacobson convincingly argues that these inter-european racial differences reached their political apex with the immigration act and the u.s. decision to close the door to overseas immigration. he contends that during the inter-war years, europe’s racial others began the slow movement toward “becoming fully white” (and thus “fully american”) through a process of civic assimilation finally completed by the end of world war ii. thus, jacobson concludes, in the post-war period, europe’s “racial” others were transformed into members of a new, broad-based “caucasian” racial group able to enjoy the full privileges of american whiteness ( ). in conversation with jacobson’s thesis, other scholars have attempted to decode the racial construction of various european immigrant groups at the time of their enter upon american soil. beginning with noel ignatiev’s how the irish became white ( ) and karen brodkin’s how jews became white folks & what that says about race in america ( ), more recent contributions to this topic include: thomas a. guglielmo’s white on arrival: italians, race, color and power in anthony antonucci | chicago, - ( ), jennifer guglielmo and salvatore salerno’s edited volume are italians white? how race is made in america ( ), and david roediger’s working toward whiteness: how america’s immigrants became white: the strange journey from ellis island to the suburbs ( ). together, this body of work introduced the next generation of american studies scholars to the power and complexity of the contingent racial formations that structured the ruling hierarchies of american social and political life and shaped national debate on immigration through the national origins act and beyond. while these studies are extremely valuable, the patterns identified by jacobson and others overlook the extent to which, by the s, anglo-americans had already developed a distinctive corpus of ideas connecting the national origin, racial identity, and moral character of various southern and eastern european groups. in fact, as this paper demonstrates, the stereotypes american nativists applied to european immigrant “others” in the late gilded age and progressive era ( - ) were prefigured in american travel writings and works of fiction produced during the early national and antebellum periods ( - ). accordingly, i argue that anglo-american reactions to immigration at the turn of the th century cannot be properly understood without reference to american ideas about race, character, and national origin established during the earlier periods of trans- atlantic political and cultural history. most notable is the fact that until the s, prevailing american notions about the racial and moral character of various european populations were formed by u.s. travelers, journalists, businessmen and diplomats operating overseas. to illustrate how ideas about race and national character formed abroad before the civil war affected national discourse and policy decisions on immigration and citizenship after , this paper focuses on a specific group of immigrants to the united states between th and th century: italians. anglo-american ideas about italian “national character” originated prior to the great waves of migration that began after italian unification in and contributed to the classification of italians among southern and european immigrants. demonstrating how stereotypes about italians first emerged at the time of thomas jefferson’s office ( - ), this paper shows how opinions about the “italian character” preceding the civil war established a legacy behind the reception of | darkest italy revisited jam it! no. may | nationalism: hyper and post italians during the peak years of their migration to the united states ( - ). more specifically, i will show the genealogy of the longest american stereotype about the italian character: their alleged criminality. the story begins in naples. vedi napoli e poi muori despite the remarkable achievement of a victory over the greatest military force on the planet during their war of independence (thanks to french support), and an equally astounding record of economic growth and territorial expansion throughout the decades prior to the civil war, americans remained deeply insecure about their intellectual and cultural achievements as a nation. above all, late th and early th century americans feared the judgement of european aristocrats about their artistic and scientific achievements. compensating for their abiding sense of post-colonial inferiority, citizens in the early republic attempted to live up to european (in particular english) standards of taste and sensibility by adopting a range of imitative cultural practices. one of the principal rituals of refinement that american citizens appropriated from their former mother country was the british tradition of taking a grand tour of italy (baker , prezzolini ). the template that inspired americans to travel to the peninsula in the years prior to italian unification had its origins in the late th century, when fashionable young aristocrats from england concluded their classical educations by setting off in a private carriage accompanied by a tutor and perhaps by a few servants on an extended sojourn to learn about the politics, culture, art, and architecture of neighboring lands. the itinerary of what became known as the grand tour varied according to fashion but typically included destinations in france, germany, the netherlands, switzerland, and above all the italian peninsula and its islands. with roman ruins, ancient monuments, lavish palaces, rich collections of renaissance paintings, and picturesque natural beauty, italy was regarded as literally: “see naples and then die,” it means that one must see the beauty of naples before dying but it also offers warning about the dangers associated with visiting naples. the origins of this famous and repeatedly cited expression remain a topic of debate. appearing perhaps most notably in johann wolfgang von goethe’s italian journey: - ( ), the phrase is a nearly ubiquitous utterance in connection with travel writing about southern italy. for an overview of the origins, practices, and itinerary of the grand tour see black . anthony antonucci | the non plus ultra of an enlightened gentleman’s education. by , the year the united states declared their independence, italian travel had grown so fashionable among well- heeled britons that samuel johnson sardonically gibed: “a man who has not been in italy is always conscious of an inferiority, from his not having seen what it is expected a man should see. the grand object of travelling is to see the shores of the mediterranean” (boswell , ). the culmination of the italian grand tour was a visit to the southern italian kingdom of the two sicilies. comprising the vast domains of mainland italy south of rome as well as the island of sicily, the bourbon kingdom and its capital city naples captured the imagination of foreign visitors from throughout late th and early th century europe. this sentiment was epitomized by johann wolfgang von goethe’s admonishment that to live fully one must first go “see naples and then die” (boswell ). across the atlantic ocean, many citizens of the rising american republic, from thomas jefferson to herman melville, shared goethe’s interest in naples and southern italy (reinhold ). the exchange that developed between the u.s. and naples prior to the invasion of garibaldi’s mille is remarkable given the contrasts between the two countries. the united states was a republic, born in revolution, out of a british colonial past. the two sicilies was instead a catholic monarchy, with roots in antiquity, formed from the union of sicily and naples in the th century and ruled by a bourbon dynasty since . at a time when italians were governed by a half-dozen rival states, american tourists travelling abroad saw the southern kingdom as a critical symbol of italian otherness. some american travelers pictured naples as a benighted land defined by indolence, criminality and backwards superstitions; others saw it as a romantic refuge; a third contingent regarded southern italy as an emerging market inhabited by people with interests in increasing trade and national standing, but who remained mired in poverty as a result of a tyrannical government. in place of the theories of difference based on genetics that emerged by the early th century, late th and early th century grand tourists attributed the poverty and from through , the two constitutionally separate kingdoms of naples and sicily were ruled as a “personal union” under the control of the bourbon monarchy. during the two periods of french invasion in southern italy ( and - ), the bourbons maintained control of sicily but lost power in naples. after the restoration of the monarchy at the end of the napoleonic wars in , the two hitherto separate (yet united) crowns were merged as a united realm called the kingdom of the two sicilies which lasted until the unification of italy in . | darkest italy revisited jam it! no. may | nationalism: hyper and post underdevelopment they perceived in southern italy to a combination of geographical and climatic determinism, atavistic social practices, and the influence of the roman catholic faith. following the lead of protestant tourists from england, americans ascribed southern italy’s social conditions to the impact of the catholic church, an institution they derided as an engine of tyranny and ignorance (franchot ). when combined, these geographic and cultural factors crystallized into a distinctive set of american ideas about southern italian national character, a short-hand term for perceived cultural differences that chauvinistically celebrated american industry and pragmatism as compared to the stereotypical southern italians’ stereotypical preference for il dolce far niente (sweet doing nothing) and indulging their passions (brand ). in keeping with the conventions of british grand tourism, american travelers kept journals of their trips; if travel was a mode of cosmopolitan education, the travel journal was the school in which the lessons were preserved. the range and tenor of american ideas about southern italians that developed on the grand tour can be observed through a brief, comparative survey of writings by three representative anglo-americans: william short ( - ), who was thomas jefferson’s personal secretary; the novelist washington irving ( - ); and the historian theodore dwight ( - ). drawing upon first hand encounters with italians in all parts of the peninsula, each of these writers contributed to american interpretations of national character, morality and politics in the kingdom of the two sicilies. un paradiso abitato da diavoli? william short was the man whom jefferson would one day refer to as his adoptive son and who would later serve as the future president’s eyes and ears in the kingdom of naples. he was born to william short (the fifth) and elizabeth skipwith at spring garden in surry county, virginia, in (cullen , - ). short came of age closely connected to jefferson and his family. the mentor-mentee dynamic that would define their life-long bond began during short’s tenure as a law student under jefferson’s former tutor, george literally, “a paradise inhabited by devils.” delivered as a description of naples and southern italy, this phrase is attributed to the neapolitan philosopher benedetto croce. anthony antonucci | wyeth, at the college of william and mary (cullen - ). sufficiently impressed by short’s “peculiar talent for prying into facts,” jefferson hired the young man in the wake of his diplomatic appointment as u.s. minister to france (jefferson ). once abroad, jefferson encouraged his protégé to visit italy, which he did in the fall of . through short’s letters – the first extensive travel letters written by an american in southern italy – jefferson enjoyed a vicarious encounter with the conditions of life on the peninsula, all the way into the heart of bourbon naples. after passing through northern italy, short set forth from rome for the kingdom of naples on january , . like dozens of subsequent other american tourists, short’s tour of naples was modeled on the british travel plan and included stops at pompeii, herculaneum, campi flegrei, virgil’s tomb, the sibyl’s cave, and an ascent of mt. vesuvius (short ). in naples, social conditions captured short’s attention first. along the way from terracina to naples, short observed that despite the region’s natural marvels, everywhere there were “numberless objects of poverty and distress.” “there must be a cruel defect somewhere,” short concluded; “most certainly it is not either in the soil or climate” (short ). the fault, he implied, layd in the kingdom’s social institutions. arriving in the capital on january, short spent seventeen days exploring the sites around the bay of naples (short ). on february short wrote a second letter to jefferson detailing his journey: he began with a description of his entrance into naples. he was astonished by the size and poverty of “the immense crowds of people which are constantly in the streets:” the human spectacle of the lazzaroni had an unsettling effect on him. “many people are pleased with this circumstance and extol the vast population of naples,” he noted, but “i confess it produced a different effect on me. these crowds are composed only of people of the lowest and poorest order. they remain there because they have no other place to go to. they are ill clad dirty and have the marks of evident and pressing poverty upon them” (short ). naples, in his eyes, was a city of the homeless. for short, the misery of the urban poor was all the more striking in contrast with the wealth and finery of the upper classes: “the middle of these streets . . . are filled with the lazzaroni were a class of people often described as street people living under a chief and were frequently depicted as beggars despite the fact that many subsisted as day laborers. in contrast to the parisian sans-culottes, the neapolitan lazzaroni were conservative monarchists fiercely loyal to the bourbon government, especially to king ferdinand iv. | darkest italy revisited jam it! no. may | nationalism: hyper and post as much brilliancy and show as are the sides with wretchedness and poverty. the most superb carriages, and fine horses with elegant trappings, are in a kind of constant procession here” (short , - ).. by may william short was back at his post in paris (jefferson ). the observations he gathered on his tour of campania conveyed to jefferson an image of the bourbon capital and its famous bay as a region marked by venerable ruins, fertile soil, and an economy in need of the liberating force of free trade. in naples, short discerned the weight of feudal oppression and monarchical despotism. sixteen years later, a twenty-two-year-old writer from new york named washington irving followed in short’s footsteps and made his own pilgrimage to the italian mezzogiorno. like short, irving found that few aspects of southern italian society stood in greater contrast to life in the united states then the gap between the luxury of its upper classes and the deprivation of the poor. in addition to praising the scenery and lamenting the kingdom’s divisions of wealth, irving characterized naples as a land of banditi (criminals). when the young writer set out northward on the overland journey from syracuse to catania, he carried his fears of southern italian brigands with him at every turn in the road. as a precaution, irving travelled with a company of eleven mounted american marines, stationed in sicily as a part of the u.s. war against tripoli, then underway. at first, the presence of a military guard gave irving some comfort but travelling through the sicilian countryside aroused his dread: “the first day we passed through several solitary places where the mountains abounded in vast gloomy caverns that seemed the very haunts of robbery and assassination” (irving , ). by the end of march , irving was ready to leave the southern italian kingdom: he admired naples’s romantic scenery and artistic treasures, but he found the contrast between the opulent few and the impoverished many dispiriting and his fears of criminal attack exhausting. travelling north through the rural parts of campania on route to the papal states, he remained anxious about banditi. passing the night at an inn in terracina, he was awakened by a mysterious sound at the door; convinced that bandits were about to assault him, he cried out for help and rushed at the door armed with a pistol, discovering that it was only a dog begging for food (irving , ). in may irving arrived at the lateran gate unscathed. to his relief, the kingdom anthony antonucci | of naples proved to be a country of peaceful, if oppressed and impoverished, people. the ubiquitous lazzaroni were irksome, but unthreatening; and despite his fears he had avoided the unwanted encounters with brigands. the real scourge of the south, the new yorker concluded, was its tyrannical elites and corrupt government officials. this was a thesis he later developed in fiction (wright ). two decades after his visit to sicily and naples, irving indeed wrote “the italian banditti,” a series of southern italy-based short stories included in his popular tales of a traveller by geoffrey crayon, gent. ( ). surprisingly, rather than the marauding fiends who haunted irving’s travels in , the southern italian banditi he depicts in his fiction are hardworking peasants driven to brigandage by poverty and corrupt bourbon officials. in the cycle’s opening tale, “the inn at terracina,” irving’s narrator explains the bandit’s heroic place in southern italian society: [the banditti] secure . . . the good-will of the inhabitants of those wild regions, a poor and semi-barbarous race, whom they never disturb and often enrich. indeed, they are considered a sort of illegitimate heroes among the mountain villages, and in certain frontier towns where they dispose their plunder . . . it is true that they are now and then hunted and shot down like beast of prey by the gens- d’armes their heads put in iron cages and stuck upon posts by the road-side . . . but these ghastly spectacles only serve to make some dreary pass of the road still more dreary, and to dismay the traveler, without deterring the bandit. (wright , - ) the italian counterparts to robin hood, irving’s brigands are what the th century historian eric hobsbawm would dub “primitive rebels or social bandits, a peasant rebelling against landlords, usurpers and other representatives of . . . the conspiracy of the rich” (hobsbawm ). irving would have agreed. for all their fearsome reputations and occasional violence, his briganti are courageous, freedom-loving rebels aspiring to a better life. they are depicted as an organized militia at war against the bourbon authorities: donning “a kind of uniform, or rather costume that designates their profession . . . to give themselves a kind of military air in the eyes of the common people,” they attack symbols of bourbon power and avenge the abuses of the king’s police (irving , - - ). in this telling, the italian banditi were nascent republicans looking to the united states for their ideals and the promise of a better life. for example, at the end of “the story of the | darkest italy revisited jam it! no. may | nationalism: hyper and post young robber,” the final tale in irving’s cycle, a french painter temporarily held captive by a troop of sympathetic banditi recounts their captain’s desire for re-birth in the land of liberty: “he told me he was weary of his hazardous profession; that he had acquired sufficient property, and was anxious to return to the world and lead a peaceful life in the bosom of his family. he wished to know whether it was not in my power to procure him a passport for the united states of america.” confident that the young bandit would find a propitious future in the rising republic across the sea, irving’s narrator declares: “i applauded his good intentions, and promised to do everything in my power to promote its success” (irving , ). washington irving was not the only writer to suggest that discontented southern italians looked to the united states as the model for their political future. the trend gained momentum in the s in response to the early stirrings of the risorgimento in the mezzogiorno and elsewhere across the italian peninsula. four years before the publication of tales of a traveller ( ), tens of thousands of ordinary sicilians and neapolitans mobilized to demand that the bourbon government adopt a program of liberal reform. led by the carbonari (charcoal burners), the secret revolutionary societies founded in naples and other parts of italy in the early th century for the purpose of defining the rights of common people against absolutism, the revolutionary coalition cultivated widespread popular support throughout the kingdom’s provinces as well as in the capital city. under the command of the celebrated generals guglielmo pepe, pietro colletta, and luigi minichini, the revolutionary movement succeeded in forcing the bourbon government to agree to a constitution on july . the changes were bold: the government’s adoption of the radical spanish constitution of provided for democratic governments at all levels, with voting rights granted to all males over twenty-one regardless of literacy (davis , ). sadly, the neapolitan attempts to establish liberal, constitutional rule did not last: in may , backed by austrian support, king ferdinand reentered naples, revoked the constitution and immediately launched a policy of repression and retribution (davis , ). after the failure of the carbonari revolution, american tourists wondered whether or not the poor, huddled masses of the mezzogiorno were cut out for self-rule. on this topic, american opinion was divided. even anthony antonucci | washington irving seemed torn, as his fiction showed. the ennobling vision of poor, southern italians turning to crime and brigandage as a means of rebellion against bourbon misrule that irving represents in his “tales of the banditti” reflects the author’s nascent support for the early stirrings of the italian risorgimento. but his faith in southern italian capacity for american-style democracy was only partial. despite the optimism he expressed about the southern italian character in the “tales of the banditti,” irving harbored suspicions that the people of the mezzogiorno were ruled by violent passions and volcanic tempers that disqualified them from republican life. for instance, in other of his italian- based short stories, southerners are depicted as people with in-born violent tempers that drown out reason and the love of liberty. irving’s “story of the young italian,” also published in tales of a traveller by geoffrey crayon, gent. ( ), recounts the tale of ottavio, a young neapolitan painter driven to commit murder after a lifetime of victimization by corrupt laws and dishonest authorities. tragically, ottavio’s unwitting act of retributive violence turns him into a fugitive, exiling him from his true love, bianca, and destroying his future as an artist. mid-way through irving’s story ottavio warns his readers: “you who are born in a more temperate climate and under a cooler key, have little idea of the violence of passion in our southern bosoms” (irving , ). the fact that a crime of passion transforms irving’s protagonist from the would-be hero of a new social order into a criminal brigand offered irving’s readers a cautionary tale that later th century american nativists recycled in the name of restricting immigration from southern europe: if southern italians were to succeed as a self-governing people they must first overcome the irrationality of their inborn tempers and control their violent passions. unlike the ambivalence expressed by washington irving in his fiction, other american travel writers pondered the nature of southern italian national character and reached damning conclusions. in the eyes of historian theodore dwight, it was clear that sicilians and neapolitans did not possess the rational temperament that was a prerequisite for citizenship in a democratic republic. rather, in dwight’s prejudicial view, southern italians were inveterate criminals whose poverty and ignorance stemmed from laziness and inability to control their passions. arriving in naples in december , dwight ( - | darkest italy revisited jam it! no. may | nationalism: hyper and post ), a twenty-five-year-old yale graduate and scion of a prominent new england family, visited the two sicilies just six months after the carbonari led revolution in july and spent five weeks in naples during the kingdom’s nine-month experiment in constitutional government ( / ). in , the same year as irving’s tales of a traveller, the future american biographer of giuseppe garibaldi and author of a popular history of the roman republic of published his first book on an italian subject, a journal of a tour in italy in the year with a description of gibraltar ( ). compared to the ambiguous depiction of southern italians presented by irving, dwight’s journal depicts neapolitans as a servile and ignorant people, congenitally incapable of bringing about their own liberation from the twin manacles of the bourbon monarchy and the catholic church. though sympathetic to the cause of liberty, dwight could find in the southern italian character no seeds of independence and no hints of a successful revolution to come (dwight , ). throughout his journal, dwight’s pessimistic claims about southern italians are supported by the testimony of his principal native informant signore mattia, a neapolitan man he befriended on the voyage from gibraltar to naples. on route mattia warns the american that all neapolitans are “great thieves,” and he volunteers to escort dwight around the city, lest he “should be cheated, robbed and perhaps murdered” (dwight , ). it is not clear whether mattia was a real person or a literary device to reinforce national stereotypes. at times he comes across as a hustler exaggerating the dangers of naples for the sake of free dinners and a tip: “many of those extravagances which seemed to stamp him as a madman, are now converted into national peculiarities. he is not, as i can see, a whit more irascible than his countrymen. they all fly into fits of passion as hastily.” in the journal mattia plays a puckish virgil to dwight’s american dante as the two men tour naples infernal streets. heeding mattia’s warning to “take care of your pockets,” and “keep your mouth shut – or they will steal your teeth,” dwight declares: “i never would condemn a nation in the gross; but i think a traveller can hardly visit naples without being struck with the disposition to cheat him manifested by almost every person with whom he has any concern” (dwight , ). if conditions were miserable inside the capital city, the rural provinces were even worse. reporting on news of the kidnapping of two english gentlemen on the main carriage anthony antonucci | road north of rome, dwight emphasized the omnipresent danger of the kingdom’s banditi: “there is very little pleasure in travelling that road, i assure you. you hardly see a man in all that tract of country who does not look as if he were half an assassin” (dwight , ). in contrast to the bleak scenes he encountered in naples, northern italy – and turin in particular – presented an encouraging prospect. there he could confidently look for the spread of liberal institutions in the hands of rational men. writing from florence several weeks after he left the south, dwight drew a sharp line between northern and southern italy: “it is going back to past centuries to land at naples: and travelling north is to move along with time and the gradual progress of society.” in contrast to naples, where lazzaroni lived in the streets and bandits infested the countryside, the people in turin appeared ready for self-rule: “the houses are good and built with much regularity, and the principal streets are as straight and broad as those of philadelphia . . . these things argued at once a superior taste for what we consider many of the necessaries and comforts of life, and the dress and comportment of the citizens proved that they had advanced an important grade in civilization” (dwight , ). in the decades ahead, dwight’s opinion, that italy’s future as a modern constitutional state depended upon the rule of the purportedly more rational, orderly northern italians, led by the savoy monarchy, over the indolent, quick-tempered criminals who lived in the south, predicted u.s. policies. indeed, throughout the peak years of the italian risorgimento and into the period of mass migration of southern italians into the united states, dwight’s bi-furcated assessment of italy’s “two halves” and the perceived differences between their respective populations came to define prevailing american notions about italy and italians. back home, dwight played a central role in translating these ideas into political action. after his tour of naples and italy in , he returned to the united states and became a leading architect of what historian howard r. marraro would later call the american view of the risorgimento “as a religious problem” (marraro ). by dwight was publicly promoting the idea that italy’s future would be best developed under the piedmontese monarchy through the american philo-italian society, an organization based in new york. along with painter and inventor samuel f.b. morse ( - ), educator henry philip tappan ( - ), and others, dwight framed the | darkest italy revisited jam it! no. may | nationalism: hyper and post movement for italian unification as a struggle between protestant enlightenment and catholic darkness. his organization’s mission was “to unite protestant christendom in this holy war” (“the christian examiner and religious miscellany” , ). where could such “protestant” leadership be found? dwight looked to the italian provinces north of rome. after dwight was a vocal supporter of the movement led by the northern italian born giuseppe garibaldi, whom he called “the george washington of his people.” throughout the decade before the civil war, dwight promoted these views alongside other prominent american supporters of the risorgimento, most of whom were fellow alumni of the italian grand tour (d’agostino , ). darkest italy comes to the united states the negative stereotypes about southern italians generated by american travelers like william short, washington irving, and theodore dwight prior to took on a special resonance in the aftermath of italian unification when, between and , more than four million italians crossed the atlantic ocean to seek opportunities and build new lives in the united states (bodnar , handlin ). while some americans greeted italian immigrants as a welcome addition to the growing foreign-born industrial work force, many others did not. in fact, to large numbers of native-born anglo-saxon americans, italians appeared as unwanted aliens – a people at once exotic and strange, possessed of in-born traits and cultural habits that rendered them less than “fit” to become self-governing citizens of the american republic. the negative qualities that late th and early th century anglo-americans perceived in southern italians were composed of a litany of slurs and “one-size-fits-all” generalizations consistent with an earlier generation of stereotypes about people from the former domains of the kingdom of the two sicilies. inflected through the lens of “scientific racism” and the burgeoning field of eugenics, by the early th century southern italians were profiled as possessing a distinctive set of physical, moral, and cultural traits that were at odds with anglo-american values. echoing tropes for overviews of this history see: deconde ; gabaccia ; carnevale ; orsi . anthony antonucci | expressed in the writings of short, irving, and dwight decades earlier, the undesirable traits americans attached to southern italians included their roman catholic faith, peasant roots, inability to speak english, swarthy skin tones, and reputations for violent mediterranean tempers. above all, between and nativists charged that italians were predisposed to criminality and criminal behaviors, including a predisposition to commit crimes of passion and participate in organized criminal conspiracies. as a result of these widely circulating prejudices and stereotypes, italian immigrants to the united states faced frequent harassment, discrimination, and persecution by american citizens and u.s. officials alike (connell and gardaphé ). the prejudices that early th century anglo- americans held about italian racial and moral character are epitomized in the language and findings of the official reports prepared by the u.s. immigration commission (the so- called dillingham commission), a congressional body composed of u.s. senators, representatives, and social scientists appointed by president roosevelt in to investigate the effects of foreigners on american life. in the dillingham commission published a volumes report on all aspects of american immigration. drawing upon the corpus of preexisting ideas about the racial and moral character attributed to italians by earlier american writers, government officials recycled antebellum stereotypes that perpetuated the long-standing notion that people from southern italy constituted an inferior race predisposed to criminality. for example, the authors of commission report volume , investigating connections between immigration and crime, declared that “italian criminals are largest in numbers and create the most alarm by the violent character of their offenses in this country” (immigration commission vol. , ). expounding upon this claim, a report published in volume (the emigration of the criminal classes) announced: an alarming feature of the italian immigration movement to the united states is the fact that it admittedly includes many individuals belonging to the criminal classes, particularly named in honor of republican senator william p. dillingham (vt), the commission reports offered a range of perspectives identifying both the positive and negative impact of immigration on american life. proponents of immigration restriction mobilized those findings that supported the nativist agenda culminating in new restrictions on immigration in (instituting a literacy test) and (instituting quotas), on route to the landmark national origins act of . | darkest italy revisited jam it! no. may | nationalism: hyper and post of southern italy and sicily . . . (and by) the not unfounded belief that certain kinds of criminality are inherent in the italian race. in the popular mind, crimes of personal violence, robbery, blackmail and extortion are peculiar to the people of italy, and it cannot be denied that the number of such offenses committed among italians in this country warrants the prevalence of such a belief. (immigration commission vol. , ) consistent with antebellum theories of italian identity, the dillingham reports divided the italian race into two separate and unequal groups. in volume , u.s. officials declared: “ethnologically there are two distinct branches of the italian race – the north and the south italian . . . it may be briefly said, however, that the north italians have a large admixture of celtic and teutonic blood, while the south italians are largely a mixed type in which greek, spanish, saracen and other blood is more or less prominent” (immigration commission vol. , - ). the fact that american immigration officials classified italian nationals into two different racial groups was unique. specifically, southern italians (or south italians as they were also labeled) were believed to belong to the latin or mediterranean ethno-racial group, whereas northern italians were a branch of the allegedly superior alpine, nordic, or teutonic racial group also claimed by the predominantly protestant, anglo-saxon people. regarding phenotypic differences between northern and southern italians, u.s. officials explained: physically, the italians are anything but a homogeneous race . . . the apennine chain of mountains forms a geographical line which corresponds to the boundary between two distinct ethnic groups. the region north of this line . . . is inhabited by a very broad headed (alpine) and tallish race, the north italian . . . all italy south of the apennines and all of the adjacent islands are occupied by a long-headed, dark “mediterranean” race of short stature . . . the bureau of immigration places the north italian in the “keltic” division and the south italian in the “iberic.” (immigration commission vol. , ) elaborating on these distinctions, the commissioners observed that sicilians in particular were “vivid in imagination, affable, benevolent but excitable, superstitious and revengeful” (immigration commission vol. , ). to support these findings, u.s. officials drew upon a vast literature on the racial identities of italians and other europeans authored by european scientists. remarkably, works by leading italian scientists and government officials, including pasquale villari, giustino fortunato, sidney sonnino, anthony antonucci | leopoldo franchetti, and francesco saverio nitti, played a fundamental role in establishing the ethno-racial taxonomies used by u.s. officials to classify italians immigrants: this literature reflected political and sociological divisions taking place within italy after its unification, in (moe ). since at least , ethnographers employed by the victorious piedmontese army reinforced the long-standing notion that the newly unified italian nation was made up of two separate and unequal parts: an affluent, modern, industrial north and an impoverished, backward, agricultural south. in line with this formulation, the vexed relationship between italy’s “two halves” defined the central dilemma of the country’s political, social, and cultural history as a unified nation-state according to a debate as old as giuseppe garibaldi (petrusewicz ). in the wake of the risorgimento and the creation of the modern italian state, the first generation of meridionalisti (southern experts), sent into the former bourbon domains by the reigning authorities based in turin, blamed the questione meridionale (problem of the south) on the people of the mezzogiorno. in the racialist thinking of the day, the southerners were considered an inferior stock to the superior inhabitants of the northern italian provinces (lumley , moe , and dickie ). across the atlantic, american nativists picked up on these pseudo-scientific distinctions and applied them to their own preexisting prejudices when italian immigrants – the great majority of whom originated in the south – began to arrive massively on american shores in the s. in one striking example, the authors of the dillingham commission’s dictionary of races or peoples ( ) drew upon the typologies developed by the influential italian sociologist alfredo niceforo to organize the racial classifications used by u.s. immigration officials to identify the psychic character of northern versus southern italians. an italian sociologist, niceforo, has pointed out that these two ethnic groups differ as radically in psychic characters as they do in physical. he describes the south italian as excitable, impulsive, highly imaginative, impracticable; as an individualist having little adaptability to highly organized society. the north italian, on the other hand, is pictured as cool, deliberate, patient, practical and as capable of great progress in the political and social organization of modern civilization . . . niceforo shows from italian statistics that all crimes, especially violent crimes are more numerous among the south than the north italians. (immigration commission vol. , - ) | darkest italy revisited jam it! no. may | nationalism: hyper and post in addition to relying on this scientific evidence of congenital criminality amongst southern italian immigrants, the dillingham commission observed that southern italians were also prone to poverty and illiteracy. these qualities were especially alarming to u.s. immigration officials because, as the commission cautioned: to the student of italian immigration to the united states the south italian movement numerically and otherwise is of by far the greatest importance . . . the numerical preponderance of the former race adds vastly to its relative importance, but in popular opinion at least, it is the character rather than the number of south italians which constitutes the real problem. it is generally accepted that the north italians . . . are more easily assimilated than their southern countrymen, who, because of their ignorance, low standards of living and the supposedly great criminal tendencies among them are regarded by many as racially undesirable. (immigration commission vol. , - ) the racialized notions of southern italian criminality expressed in the dillingham commission reports are fundamental to understanding the history of italian immigration to the united states. among them is the fact that the commission reports resonated with perceptions and conceptions about italianità that had been a pervasive component of anglo-american culture since the days of thomas jefferson and washington irving. since the period of the early republic, southern italians had been depicted by american writers as stiletto-wielding “dagoes” prone to criminal violence and “vesuvian” fits of rage, or as banditi affiliated with organized criminal conspiracies such as the mafia, camorra, and the dreaded society of the black hand (mano nera). as this paper details, during the period of mass italian immigration to the united states that took place between and , these negative stereotypes had a determinative impact on how italians were treated on american soil. from the lynching of eleven sicilians in new orleans on suspicion of criminal conspiracy in to the execution of sacco and vanzetti for murder charges connected to their involvement with anarchist politics in , the notion that italians, especially southerners, constituted an inferior race with an in-born propensity for an alteration of diego, a common spanish name, “dago” was a derogatory term applied by anglo-americans to “latins” of italian, spanish, or portuguese descents during the th and early th centuries. anthony antonucci | violence and criminality was commonly accepted, and encouraged discrimination against italian immigrants and their descendants in myriad ways (botein ). while these extreme episodes of anti-italianism are well-known, what is less known is when and how the stereotypes of italian criminality first took root in american culture. equally opaque are the mechanisms through which these notions influenced national debate about u.s. immigration policy in the late th and early th centuries. this paper demonstrates that these historical developments are intimately linked. prior to , americans who travelled, did business, and practiced diplomacy overseas gathered ethnographic information about the character of particular foreign groups, including italians, and transmitted their observations to americans back home through a stream of published and unpublished travel writing, journalism, and fiction. through this process of trans-national cultural reportage, american merchants, diplomats, and travelers compiled and spread a catalogue of prejudices and stereotypes about various ethnic and racialized national groups in europe, which defined and influenced the perception of these same groups upon their arrivals to the united states during the period of mass immigration ( s- ). the specter of southern italian criminality originated out of this particular trans-national context of encounter. the biological-based constructions of race and racial difference that emerged during the late th century can be traced back to the period before the civil war: the stereotypes about southern italy and southern italians transmitted by the first american travelers turned into a corpus of prejudices that anglo-american nativists later applied to southern italians and italians in general upon their arrival. by explaining when, how, and why americans constructed and transmitted their negative ideas about the italian character from the th century onward, this paper marks an essential step toward the comprehension of how these deep-rooted stereotypes about race, character, and criminality have shaped the experiences of italians in the u.s. moreover, analyzing the historical relationships that developed between americans and italians prior to the era of mass migration through ellis island helps us to better understand the debates surrounding u.s. immigration policy that led up to , the year the united states introduced a system of national-origin-based quotas that effectively “closed the door” | darkest italy revisited jam it!

haplo- types used by foster et al. to evaluate thomas jefferson’s alleged paternity of eston hemings jefferson, the last child of his slave sally hemings, is impressive. how- ever, the authors did not consider all the data at hand in interpreting their results. no mention was made of thomas jeffer- son’s brother randolph ( – ), or of his five sons , . sons of sally hemings con- ceived by randolph (or by one of his sons) would produce a y-chromosome analysis identical to that described by foster et al. further collaborative data (for example, the whereabouts of any of those who might have been involved at conception) are needed to confirm that jefferson did indeed father his slave’s last child, as claimed in the title. we know thomas jefferson was there, but how about randolph jefferson and his sons? david m. abbey health science center, university of colorado, teakwood court, fort collins, colorado , usa e-mail: dabbey @aol.com if the data of foster et al. are accurate, then any male ancestor in thomas jefferson’s line, white or black, could have fathered eston hemings. plantations were inbred communities, and the mixing of racial types was probably common. as slave families were passed as property to the owner’s off- spring along with land and other property, it is possible that thomas jefferson’s father, grandfather or paternal uncles fathered a male slave whose line later impregnated another slave, in this case sally hemings. sally herself was a light mulatto, known even at that time to be thomas jefferson’s wife’s half sister , . gary davis evanston hospital, ridge avenue, evanston, illinois , usa foster et al. reply — it is true that men of randolph jefferson’s family could have fathered sally hemings’ later children. space constraints prevented us from expanding on alternative interpretations of our dna analysis, including the interesting one proposed by davis. the title assigned to our study was misleading in that it repre- sented only the simplest explanation of our molecular findings: namely, that thomas jefferson, rather than one of the carr broth- ers, was likely to have been the father of eston hemings jefferson. it had been suggested to us earlier (by herbert barger, who also helped to recruit the descendants of field jefferson who par- ticipated in our study) that isham jefferson, son of thomas jefferson’s brother ran- dolph, might have been the father of one or more of sally hemings’ children. barger’s proposal was based on a statement that isham was reared by thomas jefferson; he suggested that isham could have been at monticello or at snowden (snowden was across the james river from scottsville, which is about miles from monticello) when eston hemings was conceived. but it is not known for certain that isham was at monticello at that time, whereas it is docu- mented that thomas jefferson was. from the historical knowledge we have, we can- not conclude that isham, or any other member of the jefferson family, was as likely as thomas jefferson to have fathered eston hemings. we know from the historical and the dna data that thomas jefferson can neither be definitely excluded nor solely implicated in the paternity of illegitimate children with his slave sally hemings. when we embarked on this study, we knew that the results could not be conclusive, but we hoped to obtain some objective data that would tilt the weight of evidence in one direction or another. we think we have provided such data and that the modest, probabilistic interpretations we have made are tenable at present. e. a. foster*, m.

conforms to that predicted for a mammal of the same body size and aero- bic power. volume densities of mitochon- dria in leg muscles are similar to those of mammals of the same size and aerobic capacity, whereas those in the relatively inactive flight muscles are only half as large and correspond to values reported for less aerobic mammals (table ). given that % of the rhea’s body mass consists of leg musculature, rates of oxygen uptake by mitochondria per millilitre dur- ing locomotion at the aerobic maximum appear to fall within the range reported for mammals. capillary densities in the rhea leg and flight muscles, like the mitochon- drial volume densities, also parallel values reported for the muscles of athletic and less mobile mammals. in contrast to the apparent conservation of structure–function relationships in most of the respiratory system, our results sug- gest that there are basic differences in the performance of the lungs of birds and mammals. we could not measure the lung volumes of the rheas directly, but in birds these are normally slightly more than half of those of mammals of the same mass , . the rheas therefore achieved maximum oxygen flux rates, equal to those of the most aerobic mammals of their size, using lungs that are probably only half as large. this supports the general belief that avian lungs provide relatively more function per unit volume than mammalian lungs , . although the aerobic limits of rheas and athletic mammals are similar, the metabolic power available in practice, and their func- tional needs, are not. unlike dogs, horses and other athletic mammals that sustain high metabolic rates for hours during pre- dation and migration, rheas do little or no sustained running and are poor at dissipat- ing metabolic heat loads . rheas have apparently not been under strong selective pressures like those that promoted the aero- bic power of extant running mammals. large flightless birds lead fairly inactive lives, and may have lost the ability to fly primarily because of a lack of predation. why rheas have an aerobic power that greatly exceeds their apparent functional needs remains a puzzle.

processing and molecular hpv testing in the residual ma- terial. since the bethesda system for reporting cervical/ vaginal cytology introduced the atypical squamous cells of undetermined significance (ascus) category under epithelial squamous cell abnormality [ ] . it was noted, however, by the editors of the monograph [ ] that cervical/vaginal cytopathology includes an element of subjective interpretation and consequently the applica- tion of criteria should be viewed within this context. nu- key words thinprep test · papanicolaou test · human papillomavirus · reflex test · cotesting ·

molecular laboratory has no record of cobas ® hr hpv testing alone. discussion in the last decade it has become clear that infection with hr hpv is required for the development of most cervical cancers and high-grade precursor lesions. recent emphasis on molecular testing seeks to identify infection with hpv strains considered a high risk for carcinogen- esis. the clinical use of hpv testing started as additional screening for patients with ascus cervical cytology re- sults in order to determine the need for colposcopy [ ] . in our hospital practice, hr hpv reflex tests, automati- cally ordered by the cytology laboratory for ascus re- sults, were performed from (when covered by insur- ance) and continue through the present. in women years and older, the hr hpv assay can be used in combination with cervical cytology to adjunc- tively screen for the presence or absence of hr hpv types. this information, together with the physician’s as- sessment of the cytology history, other risk factors, and professional guidelines [ ] , may be used to guide patient management. table  shows that hpv cotesting at thom- as jefferson university hospital started in and pro- gressively increased from to % by . at the same time, the decrease in pap testing is striking from , in when the percentage of hpv testing was %, to , in with % utilizing hpv testing. it is known that a negative hr hpv test represents a low risk of de- veloping disease over years and safely allows lengthen- ing of the test interval. this rationale is reasonable to ex- plain our observed decrease in pap testing. also notice- able is the percentage decrease in hpv reflex testing and increase in hpv cotesting. most likely this was the result of increased adherence by practitioners to cotesting guidelines [ ] . of interest is the similar hr hpv detection rate in both reflex ( , , %) and cotests ( , , %) for the hpv assays, as shown in table  . the follow-up biopsies for ascus cases, when avail- able, revealed cin or in % of cases detected by hc ® and cobas ® and % by cervista ® . several biopsies showed absence of cin, and quite a few cases were fol- lowed only by negative pap tests. for cotesting, – % of negative pap tests showed cin in the follow-up bi- opsy. the majority of cases had only negative pap tests for follow-up. most low-grade squamous intraepithelial lesion cases were confirmed by cervical biopsy and all high-grade squamous intraepithelial lesion cases were confirmed by histology as shown in table  . it is not sur- prising that no cases of cervical carcinoma were found, since our female population is at low risk for cervical cancer. table  illustrates the number of hpv reflex tests with the cobas ® platform in , separating the hr hpv / ( = %) from other hr hpv types ( = %). follow-up shows % of the hpv / cases had subse- quent biopsies, in comparison to % for other hr hpv cases. a trend towards higher cin / for hpv / was noted. the lack of demand for hr hpv stand-alone testing in our institution is of interest. major changes to screen- ing guidelines in the last decade include initiation of screening at the age of years, conservative manage- ment of young women with abnormal cytology, ex- tended screening intervals for women aged ≥ years and cessation of screening in low-risk women over the age of years [ ] . hr hpv is a prerequisite for the development of almost all types of cervical cancer, therefore hr hpv has become an integral part of new screening strategies. with the fda approval of the first hpv test for primary cervical cancer screening of wom- en ≥ years [ ] , clinicians in the usa now have dif- ferent first-line screening options that they may offer to patients: the pap test, cotesting with pap and hpv, and hpv testing as a stand-alone test [ ] . the choice of the cervical screening method may vary for a variety of reasons including patient and provider preference along with geographic, socioeconomic, and practice settings. http://dx.doi.org/ . % f cytology practice before and after hr hpv testing acta cytologica ; : – doi: . / conclusions it is evident in our practice that thinprep pap testing decreased from , to , ( %) over years, while the percentage of hpv molecular testing (reflex plus co- testing) increased from to %. the decrease in pap testing is most likely due to an increased interval between tests when cotesting results were negative. the hpv de- tection rates assessed during a -month interval showed that the hr hpv assays used, namely hc ® , cervis- ta ® , and cobas ® , detected similar rates of hr hpv. a trend was noted towards higher-grade cin in the follow- up of hpv / detected cases. so far, the choices of the cervical screening method in our practice include the pap test, hr hpv reflex test and cotesting with no demand for the hpv stand-alone test. disclosure statement none of the authors have any relevant financial disclosures to report. references the bethesda system for

cutaneous melanoma. vi- sual acuity was / od and / os. the melanoma measured mm in basal dimension and mm in thick- ness (figure, a). iodine plaque radiotherapy was performed. two months after therapy, the patient reported development of a noninflammatory, painless, circumscribed halo around numerous previously pigmented cutaneous nevi, and ne- vus lost nearly all pigmentation (figure, b-e). at months, the uveal melanoma regressed to . mm in thickness. meta- static evaluation findings were negative. comment. cutaneous melanoma can stimulate vitiligo or halo nevi through immune mechanisms. the pro- posed pathophysiology involves cytotoxic t-cell– mediated immune reaction targeted against antigens shared between normal melanocytes and melanoma cells such as mart- , tyrosinase, gp , tyrp , and tyrp . histopathologically, a lymphohistiocytic infiltrate pre- dominated by cd and cd t cells has been observed at the margin of such depigmented lesions. immuno- therapeutic strategies for cutaneous melanoma have been attempted based on this observation. in , nirankari et al described a -year-old man who underwent evisceration for panophthalmitis from undetected uveal melanoma. he developed vitiligo at years and orbital recurrence of uveal melanoma at years, for which orbital exenteration was performed. in , albert et al described patients with skin depigmenta- tion following enucleation for melanoma. case was a -year-old man who developed vitiligo years after enucleation, and case was a -year-old man who de- veloped cutaneous halo nevi year after enucleation. al- bert and colleagues speculated that this represented a heightened host response and more favorable progno- sis. in , duh et al described a -year-old woman with a . -mm-thick uveal melanoma who developed vitiligo years after enucleation. these reports suggest a possible role of the immune system following therapy of uveal melanoma, similar to cutaneous melanoma. we are not aware of other cases of cutaneous halo nevi de- veloping after plaque radiotherapy for uveal melanoma. the association of cutaneous halo nevus or vitiligo with treated uveal melanoma could be more frequent be- cause these dermal findings can be subtle, as in our case. author affiliations: department of ocular oncology, wills eye institute, thomas jefferson university, philadelphia, pennsylvania

mellon university user on / / targets & mechanisms scibx: science–business exchange copyright © nature publishing group � grk : big-hearted target? by michael j. haas, senior writer a team of u.s. and u.k. researchers has uncovered a new role for g protein–coupled receptor kinase in pathological cardiac hyper- trophy, providing a first mechanistic target for this indication. it behaves more like an histone deacetylase kinase than a g pro- tein–coupled receptor kinase, activating histone deacetylase and triggering a signaling cascade that results in cardiac hypertrophy. the finding, reported in the proceedings of the national academy of sciences, may make it possible to treat hypertrophy with kinase inhibitors. in contrast to current therapeutic strategies that address more general conditions such as hypertension or ischemia, which can lead to cardiac hypertrophy, this research provides the potential to treat the condition directly at its mechanistic root. however, the effectiveness of such a therapeutic strategy will depend on whether the function of g protein–coupled receptor kinase (grk ) is unique in hypertrophy or is redundant with other histone deacetylase kinases (hdac kinases). the team of scientists from thomas jefferson university and university college london was led by walter koch, vp of research in medicine, professor of medicine and director of the center for translational medicine at thomas jefferson. “grk has been shown to be increased in heart failure,” koch told scibx. “consequently, it made sense to study it in hypertrophy. our work shows that myocytes with high grk levels are primed for hypertrophy.” failure of mighty-hearted mice left ventricular hypertrophy (lvh)—also known as pathological or maladaptive cardiac hypertrophy—is a condition in which the heart grows and accumulates scar tissue in response to stress, such as hypertension and injury. this enlargement compromises heart function over time and leads to heart failure. there are no approved therapeutics to treat hypertrophy. grk , a membrane-bound protein expressed in most tissue types, regulates signaling and function in myocytes. it is also known to be upregulated in pathological cardiac conditions such as heart failure, but how it contributed to those conditions was unknown. , “there are two grks in the heart—grk and grk ,” koch said. “previously we have focused on grk , which has a pathological role in heart failure, but we were also interested in hypertrophy.” last year, koch and colleagues at thomas jefferson university described how grk signaling accelerates heart failure in a heart whose function is already compromised. in an unpublished study conducted in by koch while at duke university medical center, mice that overexpressed grk were subjected to aortic banding, a surgical procedure that creates resistance to blood flow out of the heart, thus putting stress on the organ. koch’s group found that about % of these mice died of heart failure, compared with about % of mice having normal grk expression. ex vivo analysis revealed excessive hypertrophy in the grk - overexpressing mice, he said. koch said that prior to aortic banding “the hearts of the grk - overexpressing mice are slightly larger than normal but have no loss of function. the mice are healthy and normal until they are stressed.” in a team at university college london led by julie pitcher, senior lecturer of pharmacology and coauthor on the pnas paper, showed that grk contains a nuclear localization sequence that allows it to translocate from the membrane to the nucleus of myo- cytes in response to g protein–coupled receptor (gpcr) signaling. previous work by others had also shown increased nuclear localiza- tion of grk in a rat model of cardiac hypertrophy. together these results led pitcher to suggest that grk may have a role in modulating gene expression linked directly to hypertrophy. based on these two studies, koch’s team hypothesized that nuclear grk played a direct role in pathological hypertrophy via transcrip- tional regulation of genes responsible for this condition. to investigate their hypothesis, the team first repeated koch’s aor- tic banding experiment in grk -overexpressing mice and obtained similarly high rates of heart failure and mortality. ex vivo analysis showed both a significant increase in heart size and a greater accu- mulation of grk in the nucleus of myocytes relative to what was seen in mice with normal grk expression. by contrast, mice that overexpressed a mutant form of grk that lacked the ability to cross the myocyte nuclear membrane showed no increase in heart size or heart failure in response to aortic band- ing—suggesting that grk ’s nuclear function was indeed critical to hypertrophy. next, in vitro experiments demonstrated that stress-induced gpcr signaling in myocytes activated guanine nucleotide binding protein, q polypeptide (gq; gnaq), thereby triggering upregulation of grk , which then translocated to the myocyte nucleus. in the nucleus, grk activated histone deacetylase (hdac )—a class ii hdac—which then translocated to the cytosol, where it activated myocyte enhancing factor (mef ; d-mef ), a transcription factor known to upregulate expression of hypertrophic genes. the team said its results collectively demonstrate that grk is a class ii hdac kinase that plays a critical role in the development of cardiac hypertrophy in response to cardiac stress. koch acknowledged that the effects of grk ’s role in hypertrophy are probably exaggerated in his team’s mouse model because the mice http://www.scibx.com scibx: science–business exchange copyright © nature publishing group � targets & mechanisms overexpress grk . nonetheless, the findings should be relevant in animals with normal grk expression because hypertrophic stimuli result in the nuclear localization of grk in such animals as well, he said. best heart target researchers contacted by scibx agreed that koch’s team had identi- fied an important mechanism in the development of cardiac hyper- trophy, but they disagreed over whether the findings would easily translate into a therapeutic to treat the condition directly. suraj shetty, lab head and project team leader of cardiovascular and metabolism research at novartis ag’s novartis institute for bio- medical research, said that “hypertrophy is a harbinger of adverse cardiac events like heart failure. hence there has been a move to identify key targets involved in hypertrophy.” he added that nuclear factors involved in hypertrophy—such as the nuclear form of grk —are of particular interest because they could represent nodal points strategically located at the convergence of several different hypertrophic signaling pathways. “you want to be as downstream as possible to have the most impact,” he said. however, he noted that at least three other class ii hdac kinases are known: calcium/calmodulin-dependent protein kinase ii (camkii), protein kinase d (pkd) and microtubule affinity-regulating kinase (mark). “there might be some redundancies among these kinases,” shetty said. “so the question is whether grk is the key hdac kinase responsible for mediating pathological hyper- trophy” or whether the other kinases could compensate if grk is inhibited, he said. “we would need to ascertain the relationship and redundancy among these kinases” before determining that grk is a valid target, he said. “certainly there are redundancies,” koch agreed. “but these kinases act differently depending on the type of stress and which receptor system is activated.” he added that it isn’t yet known if grk is part of other receptor pathways, a question that is the focus of an ongoing study. junichi sadoshima, vice chair and professor of cell biology and molecular medicine and associate director of the cardiovascular research institute at the university of medicine and dentistry of new jersey, was more sanguine about grk ’s potential as a target. “this paper is very interesting because i believe the signaling mechanism regulating hdac translocations is really critical to pathological cardiac hypertrophy,” he said. “if this pathway is relevant for stimulus such as high blood pressure and ischemia, then grk could be a druggable target,” sadoshima said. sadoshima also wanted to know how grk is transported from the membrane to the nucleus. “if the molecule that associates with grk to move it to the nucleus could be identified, that could be a good target,” he said, and possibly preferable to grk because of the known difficulties in targeting kinases. novartis’s shetty said whether this unknown transporter would be a good target would depend on how specific or general its function is. “if the chaperone molecule is a general factor involved in nuclear shuttling, then targeting it could have severe side effects,” he said. in novartis began a phase iv trial comparing diovan valsartan plus the generic amlodipine to cozaar losartan plus the generic hydrochlorothiazide for the treatment of pathological hypertrophy. novartis markets diovan, an angiotensin ii receptor antagonist, to treat hypertension. merck & co. inc. markets cozaar, also an angiotensin ii receptor antagonist, for the same indication. direct benefit shetty said that treating pathological hypertrophy indirectly—by treating underlying conditions like hypertension—minimizes hypertrophy and protects against adverse cardiovascular events such as heart failure and arrhythmia. but he noted that growing evidence suggests that treating hypertrophy per se might confer similar protection. according to shetty, researchers had hypothesized that cardiac hypertrophy was a beneficial compensatory response to stress, and therefore inhibiting it directly would be detrimental. but that hypoth- esis has been challenged by short-term in vivo studies showing inhi- bition of pathological hypertrophy—induced in animals with otherwise normal blood pres- sure—is in fact beneficial. “this raises the possibility that inhibition of pathological cardiac hypertrophy per se could have salutary effects,” shetty said. “thus a concerted effort is underway to ascertain the long-term benefits of inhibition of hypertro- phy per se in the context of heart failure.” sadoshima believes direct treatment of hypertrophy might have several benefits. “regardless of the nature of the initial triggers—hypertension, ischemia, angiotensin and so on—many stimuli that induce patho- logical forms of hypertrophy utilize the hdac-mef pathway,” he said. “thus inhibitors of hdac kinases would be effective in many forms of pathological hypertrophy and have broad application against many forms of heart failure.” by contrast, sadoshima said blocking hypertrophic mechanisms upstream from grk and hdac—for instance, at the level of recep- tors or cytosolic kinases that have many cellular functions—could have undesirable side effects. “if you inhibit hypertrophy at final steps of signaling in cells, you can expect more targeted effects,” he said. sadoshima also speculated that specific inhibitors of hdac kinases might have fewer systemic side effects than inhibiting upstream targets, because class ii hdacs are mostly expressed in terminally differentiated cell types. besides investigating whether grk ’s action on hdac is redundant with other class ii hdac kinases, koch said the team is attempting to elucidate the specific mechanism of binding between grk and hdac . “this would give insight into how hdac is regulated by grk ,” he said. “if we know this, we could put small peptides into the nucleus to block that interaction.” “if this pathway is relevant for stimulus such as high blood pressure and ischemia, then grk could be a druggable target.” —junichi sadoshima, university of medicine and dentistry of new jersey scibx: science–business exchange copyright ©

up their own minds this week when a unique combination of science and reality tv gets its first screening. billed as both entertainment and serious research, the bbc programme the experi- ment attempts to recreate aspects of a psychology study by stanford university researcher philip zimbardo. in the original study, volunteers were asked to assume the role of either prisoner or prison guard, and were placed together in a simulated jail. those acting as guards were so brutal to the prisoners that a shocked zimbardo abandoned the experiment and said that it should never be repeated. it is now seen as an important demonstration of how social circumstances can make people conform to particular roles. but whereas the stanford guards bullied the prisoners and forced them to clean toilets with their bare hands, their british counter- parts tried to befriend the prisoners and even agreed to reorganize the prison as a com- mune. an edited version of the -day trial, held last december at a london television studio, will be shown in four one-hour programmes beginning this week. “this has been a ground-breaking collab- oration between academia and the media,” says alex haslam, a psychologist at exeter university who planned the experiment with steve reicher, a researcher at the university of st andrews and joint editor of the british journal of social psychology. “it is not a media creation on which psychologists were invited to comment. the guiding principle for us and the bbc was always the science.” others warn, however, that it is difficult to compare the two studies directly, as behav- ioural trials are hard to replicate. the tele- vision cameras will also have had “an immedi- ate constraint on what people do”, says donald laming, a psychologist at the univer- sity of cambridge. zimbardo, still at stanford university, could not be reached for comment. for the experiment, male volunteers were recruited through newspaper adverts, and divided into guards and prisoners. the prisoners shared cramped cells and carried out chores, whereas the guards enjoyed better food and separate rooms and were given lim- ited powers over their charges. as well as observing and recording the behaviour of the volunteers, haslam and reicher asked them to complete psychometric tests and analysed their saliva for the stress hormone cortisol. it soon became clear that the guards were news nature | vol | may | www.nature.com unable to organize themselves. “there was a lack of a common social identity, no leader- ship and they didn’t even develop a simple shift pattern,” says reicher. the guards showed more psychological stress than the prisoners. haslam says that he welcomed the chance to challenge the stanford results, and claims that the guards who behaved as tyrants in the original experiment did so only because they were encouraged to. n reality tv show recreates famed social study broadcasting behind bars: the experiment aims to explore how

their family club, despite dna evidence published in nature suggesting that he fathered at least one of her children. the monticello association, a group of nearly descendants of jefferson’s daughters, voted on may to keep sally hemings’s descendants out of their group. this means that hemings’s relatives cannot be buried in the graveyard at monticello, jefferson’s home in charlottesville, virginia. their vote is the latest twist in a racially charged controversy that has raged since jefferson’s own day, when it was noted that sally hemings’s children bore a likeness to the third president. that and other evidence fuelled speculation that the author of the declaration of independence fathered six children by hemings, who was a slave at monticello. she only became pregnant during times when jefferson stayed there. jefferson’s descendants have always disputed this speculation. jefferson’s grand- children claimed that one of his maternal nephews, samuel or peter carr, fathered hemings’s children. but genetic tests pub- lished in november (see nature , – ; ) eliminated that possibility. the tests compared the y chromosomes of men descended from sally hemings’s son eston with those from the jefferson and carr family lines. eston’s y chromosome was found to be virtually identical to jefferson’s and dissimilar to the carr chromosome. the study caused an outcry because it was published in the midst of then-president bill clinton’s impeachment process. clinton’s supporters seized on it as proof that previous presidents — even the most celebrated ones — had also engaged in sexual indiscretion. the findings prompted the thomas jefferson foundation, which owns and operates monticello, to investigate the hemings connection. in january , it concluded that the dna study, combined with other evidence, indicated a “high prob- ability that thomas jefferson fathered eston hemings, and that he most likely was the father of all six of sally hemings’s children”. but jefferson’s descendants remain unswayed, and now say that thomas’s brother randolph was probably eston’s father. “they have not provided conclusive evidence that thomas jefferson had a relationship with sally hemings,” says nathaniel abeles, the monticello association’s president. the association’s position cuts no ice with the academic community. “this decision is scientifically unsound, historically unsound and morally bankrupt,” says annette gordon-reed of the new york law school. “the issue is pretty much settled and the fact that the family association chooses to tell a story about itself doesn’t affect what scientists or historians think.” n b b c monticello, home of thomas jefferson, where his slave’s descendants have been denied burial. j. s o h m /c h r o m o so

pacing (teap) is used for temporary treatment of hypotension and/or low cardiac output caused by sinus bradycardia or atrioven- tricular junctional rhythm. it can also be used for temporary overdrive pacing of reentrant tachycardias. a pacing esophageal stethoscope (pes) is easy to place in supine intubated patients. however, no guidelines exist for pes placement in the prone or laterally positioned intubated patient. methods: after irb approval and written informed consent, an fr pes with cm depth markings (model cardiocommand, inc) was inserted to a depth of insertion (doi) of cm from the edge of the maxillary alveolar ridge into the esophagus of adult intubated patients in the supine position. with the pacing rate set – beats per min faster than the patient’s intrinsic heart rate and the current output on the pulse generator (model a) set at its lowest current setting ( . ma), the current was gradually increased until atrial capture was achieved. the minimum current producing continuous atrial capture throughout the respiratory cycle was recorded as the pacing threshold. the pes was then with- drawn cm at a time and pacing thresholds were re- determined for each

j. schwarz the american revolutionaries so re vered the rule of law that they relied on the law to help rule their slaves. an apostle of republicanism in the united states, thomas jefferson is no exception to this generalization. he faced the same dilemma as did other slave-holding ameri can revolutionaries. how could the de fenders of liberty simultaneously deny liberty to the african ameri- . cans whom they held to slavery? how could they be slave holders without denying liberty itself? some revolutionaries answered these ques tions by freeing their slaves. jefferson chose not to ( ). thomas jefferson's legal transactions con cerning his bondspeople reveal that part of his answer to the problem of slavery in a revolutionary, republi can society was to make certain of the legality of his behavior as a - master. he believed that confor mity to the law of slavery constituted a civic duty, protected him from some of the dangers inherent in slavery, preserved his liberty to hold humans in bondage, and even secondarily gave some personal se curity to the enslaved. jefferson's legal oversight of african americans at monticello and elsewhere is revealed in his legal transactions concern ing his human property, which spanned more than half a century. these transac tions created a unique, rich, and nearly unrivalled record of the relationship be tween written laws and human behavior in a representative, developed slave society ( ). this essay focuses on the manner in which jefferson translated statutory law into practice or made practice into cus tomary, unwritten law, that is, his planta tion rules. thanks to jefferson's careful how could the defenders of liberty simultaneously deny liberty to the african americans whom they held to slavery? retention of his papers, we can reconstruct a better picture of his legal relationship to the bondspeople under his dominion than in almost any other case ( ). for example, among jefferson's pa pers are agreements, wills, and other docu ments by which slaves were transferred from one generation of the jefferson fam ily to another. to be sure, these transfers normally benefitted jefferson, but these and jefferson's other legal transactions concerning slaves show how the law of slavery also placed him and other slave owners within the confines of a prescribed system that was supposed to command their obedience just as it was meant to help them command their slaves. the day-to day transactions of slave holders, such as those by which jefferson family members inherited human property, are notable for their routine, prosaic quality. one , can find similar transactions con cerning bondspeople in the records of slave societies throughout the western hemisphere. these ar rangements provided some predict ability and security, two essential aspects of law. but the system of property laws, other civil laws, and criminal laws reflected in these docu ments also constrained slave own ers?whether they held two or two hundred people. control was the sine qua non of slave ownership. the law of slavery helped people like jefferson control the wills of their human chattel to some ex tent. uncontrolled, the wills of chattel could become the wills of human beings, threatening slavery and endangering prop erty or people. however, neither statutory nor customary laws concerning slave gov ernance were as effective in controlling bondspeople as were straightforward prop erty laws in safeguarding ownership of human property. treating people as prop erty to be bought and sold was one thing. oah magazine of history summer it was quite another thing to act as if those human commodities lacked wills. none did, so enslaved people always had the potential of contradicting the neat catego ries by which slave holders attempted to rule, even when those categories were incorporated into laws. consider the con stant worry of slave holders about fugi tives, as reflected in jefferson's often-quoted virginia gazette advertise ment of for a runaway slave ( ). old dominion law gave owners of "slaves who stole themselves" some help in find ing them, and it assured that once they did, there were legal means of establishing ownership. it is questionable, however, how much good the law did jefferson: while almost every man who ran away from him was initially captured and re turned, nearly every one of these run aways ultimately proved uncontrollable and often ran away again, sometimes per manently. still, noblesse oblige was within the reach of the slave master. the law of slavery allowed for acts that could reas sure slave holders of their legitimacy. the rationale for the customary laws of slavery by which jefferson was supposed to con trol his slaves was that bondspeople must be extensions of the will of their owner. this paradoxically allowed jefferson to delegate to african americans powers ordinarily reserved to whites. he could even base important decisions about his slaves on their preferences or behavior; he also sometimes paid them for unusual tasks. but jefferson was unquestionably capable of angrily asserting his rights when slaves claimed at least by their actions that they had customary rights that clashed with his. private and public accusations of criminal behavior against jefferson's slaves involved both customary law and statutes. "misbehavior"?violations of jefferson's mostly spoken plantation or customary law?occurred fairly regularly, bringing into play his conception of him self as lawgiver and law enforcer. jefferson could order whippings or even far more severe punishment when he thought it necessary. he also had fairly clear ideas concerning the differentiation between his enforcement of plantation law and gov ernmental enforcement of statutes. when a bedford county slave court gave three of his poplar forest slaves a light sentence after convicting them of attacking their overseer, jefferson promptly sold the three. it was part of the customary law of his plantations for jefferson to provide at least minimal protection of his slaves against various dangers, such as neglectful or bru tal hirers, as a corollary to his shielding of himself and his agents from certain slaves. jefferson paradoxically assumed, however, that the ultimate method of protecting his bondspeople was to keep them in bond age. hence there are few manumissions recorded in jefferson's papers, most of them in his will. but when jefferson chose to free any of his human property, he had to contend with statutes that both empow ered and limited him in more complex ways than did any laws concerning run mount vernon ladies' association archaeology department artifacts recovered from the excavation of a slave quarter cellar at mount vernon. oah magazine of history summer aways or alleged criminals. jefferson's attitude toward both bondspeople and the laws of virginia influenced his decision to free several members of the hemings fam ily. his testamentary petition for an ex ception to the old dominion law that required most emancipated people to leave the state reflects his assumptions that the state lawgivers would grant his wish and that only these enslaved men would be capable of living in freedom. still another way jefferson encoun tered the strictures of the slave code un derlines the reciprocal nature of his link to that body of laws. that was when other people entrusted him with the disposition or protection of their slave property as a trustee, agent, legal advisor, or lawyer. in these and other instances, thomas jefferson accepted the laws of virginia, thomas jefferson memorial foundation, inc. overhead view of the largest of the slave dwellings on mulberry row at monticello. the ethics of his one-time profession of lawyer, and the canons of his class. living in a world of shared obligations, preserv ing their reputation among slave-holding peers, and choosing to keep their slaves, jefferson and other slave owners had no choice but to acknowledge the force of slave law. yet is it not fair to expect more legal creativity from thomas jefferson than from other slave owners of his time? relatively vigorous in his public pronouncements on abolition in the s and s, he main tained silence thereafter. his greatest creativity concerning his bondspeople was limited to the de facto manumissions of beverley and harriet, children of sally hemings, and his unusually clear articula tion of his slaves' peculium, or right to the fruits of some of their labor. the problem was that the law of slavery virtually stifled any more creativity than this. the root of jefferson's subjection to the law of slavery was his decision to remain a slave holder. as long as he held human property, jefferson never could escape from slave law. while in public office, he was called upon to make legal decisions about slaves and slavery. dur ing the early years of his public service he made some antislavery pronouncements ( ). his governmental actions, which carried greater practical weight than did his pronouncements, were rarely antisla very. every time he took the side of progress and enlightenment, he encoun tered self-interest and the hard realities of economic and political life in the new nation ( ). sought after regularly for his opinion concerning slavery during his years of retirement, jefferson insisted upon pub lic silence. under the heavy pressure of events such as the missouri controversy, he privately pronounced with insight on the nation's problem of slavery without being able to offer a solution. his tortured formulation of the dilemma he thought lawmakers and enforcers like him faced? to his mind the impossible choice between giving up the benefits of the law of slavery and eliminating that law's self-evidently unjust consequences?reflects his pain and ambivalence: "but as it is, we have the wolf by the ear, and we can neither hold him, nor safely let him go. justice is in one scale and self-preservation in the other" ( ). this is not to say that jefferson was a mere product of his times who failed to solve a problem that very few people solved. in other respects, jefferson helped to "produce" his times. yet he refused to go as far as his neighbor edward coles, who emancipated his slaves; jefferson also failed to emancipate more than a handful of slaves in his will?in contrast to such contemporaries as george washington and john randolph of roanoke. "was tho mas jefferson an authentic enemy of sla very?" david b. davis asked in ( ). was thomas jefferson willing and able to act against his own interest in slave prop erty? the latter is a question that hits close to home because it touches on how jefferson lived, on what the laws of his slave society allowed, and on his concep tion of himself as an enlightened ruler. slave owners did enjoy a certain amount of independence from govern mental oversight of their "management" of slaves. in return for the protection provided by the laws and judiciary of any slave society, however, slave holders had to pay the price of abiding by the regula tions that laws and the judiciary applied to owners. jefferson and other holders were unwilling to take the risk of rejecting governmental regulation of them and their human chattel because of the very nature of their legal relationship with bondspeople. they regarded slaves as oah magazine of history summer _thomas jefferson memorial foundation, inc. archaeological excavations on mulberry row unearthed an assortment of objects used by the slaves after work and on sundays or holidays. shown here are a fragment of a writing slate (with inscribed words), pencils, a penknife, dominoes, marbles, a jews harp, and part of a fiddle bow. their property. had they rejected the governmental regulation of that "species of property," they would have jeopardized much of the law of property and the soci ety and economy in which they lived. the only way out of these difficulties was to free all of one's slaves. this thomas jefferson was unwilling to do. jefferson's legal transactions con cerning human chattel reveal that he had the wolf by just one ear, a particularly precarious circumstance. it was as if slavery were the wolf, and the law of slavery could not always protect slave owners from trouble that could ultimately be blamed on that wolf. "in a word," declared an anonymous letter writer in , "if we will keep a ferocious monster in our country, we must keep him in chains .... slavery is a monster?the most horrible of all monsters" ( ). the law of slavery only supported, and did not guarantee, the security of slave owners. that was to be expected: no law has ever been able to guarantee security. but the wolf (slavery) was especially dangerous. jefferson also could not es cape the contradiction between his role of master and the ideals of the american revolution. subjecting himself to the rule of law?required behavior for any repub lican leader?did not work. "the slave holder can never be a democrat," declared a "gentleman" in a newspaper letter in ( ). what then was a leader of a republican revolution and of the demo cratic-republican party to do if he also chose to keep his slaves? the best he could do was to act like an enlightened monarch whom laws limited and empow ered, and who reserved the right to make some laws of his own. it is this "bargain" between the osten sibly independent slave owner and the government that helps considerably to explain the sharp conflict between jefferson's pronouncements about slavery and his actual ownership of bondspeople. jefferson could not have it both ways: as a slave owner, he either had to obey the laws of slavery while he kept african ameri cans in bondage or else free all slaves and not have to abide by the slave code. any one who acted like an enlightened mon arch could not be a republican leader of human beings when they were in bondage. no matter how beneficent a master he may have been, he still was an owner of per sonal chattel. that committed him to support the law of slavery and to preserve the peculiar institution. unique and ex traordinary in some ways, and often the beneficiary of the laws, he was just as thomas jefferson memorial foundation, inc. _____________________________________f _i?f^? ;''t-_i___^_l__^_____-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_p^"' ^^^^i_________________________h ________________ri' ip __________________ ' ^_____ ______h ________________________________________%? : ' '^mm^^^^^^^^^^^m ,*'^^rr^l*,l^^^^^^^m some objects found during excavations of mulberry row show that african traditions were very much alive within the monticello slave community. pictured here are a cowrie shell, a carved horn ring, and two pierced eighteenth-century spanish coins. oah magazine of history summer subject to the law of slavery as any other slave owner. the approximately per cent of his enslaved laborers who remained in bondage as the property of at least twenty-one new owners after jefferson's death were living proof that the law of slavery was written on their skins immea surably more than on jefferson's, that they lived under the govern ment of men as well as of laws; yet his unwillingness or inability to free those people is partly attribut able to the way in which the law of slavery was also written on jefferson's skin ( ). endnotes . for conflicting viewpoints con cerning jefferson's choice, see paul finkelman, "jefferson and slavery: treason against the hopes of the world,'" in jeffersonian legacies, ed. pe ter s. onuf (charlottesville: the university press of vir ginia, ), - , and or lando patterson, "the unholy trinity: freedom, slavery, and the american constitution," social research (autumn ): - . . for a discussion of the law of slavery, see philip j. schwarz, twice condemned: slaves and the criminal laws of virginia, - (baton rouge: louisiana state university press, ), - , and the many articles in paul finkelman, ed., slavery, race and the american legal sys tem, - (new york: garland, ). . the major collections of jefferson manuscripts are at the huntington library, the library of congress, the massachusetts his torical society, and the alderman library, university of virginia. all these collections are available on mi crofilm. the most recently published edition of jefferson's writings covers only through the beginning of the s. julian p. boyd etal., eds., the papers of thomas jefferson (princeton, n.j.: princeton univer sity press, - ). the best recent survey of african-american monticello is lucia c. stanton, "those who labor for my happi tracy w. mcgregor library, university of virginia ^^^tjmjr-'p wax-'xx ' ! born a slave at monticello, isaac jefferson worked there for many years as a blacksmith, tinsmith, and nailmaker. at the time of this photograph, he was a free man practicing his ironworking trade in petersburg, virginia. ness': thomas jefferson and his slaves," in jeffersonian legacies, ed. peter s. onuf, - . . virginia gazette (purdie & dixon), september , reprinted in boyd et ah, eds., the papers of thomas jefferson, i, , or transcribed in lathan windley, ed., runaway slave advertisements: a documentary his tory from the s to (westport, conn.: greenwood press, ), v. . virginia and north carolina, . . the most famous pronouncements are in his notes on the state of virginia (new york: harper & row, ), - . . see, e.g., douglas r. egerton, gabriel's rebellion: the virginia slave conspiracies of and (chapel hill, n.c.: the university of north carolina press, ). . jefferson to john holmes, april , , jefferson papers, library of congress, microfilm reel ?a polygraph copy of the original. all published transcriptions of this letter erroneously misquote "ear" as "ears," a crucial difference for the person holding the wolf. . oxford, . much of this lecture is incorporated into davis's the problem of slavery in the age of revolution, - (ithaca, n.y.: cornell university press, ). .

each corresponded to a decrease in binding energy of about . rt. in fact, the binding energy de- creased linearly as a function of the number of i v mutated subunits. these results suggest that despite being tethered to a particular subunit, the single in- activation particle has sufficient freedom to interact with position of each subunit with roughly equal probability. where does this freedom come from? it is expected that the inactivation gates enter the cavity through lateral ‘windows’, similarly to k þ . can our single tethered inactivation gate enter through each of the four windows of the protein? we will address this question by making individual cysteine mutations at each window and testing the inac- tivation gate’s binding kinetics after chemical modification. -pos board b gating interactions between the cytoplasmic t domain and pore of a kv channel brian urbani, manuel covarrubias. jefferson medical college of thomas jefferson university, philadelphia, pa, usa. whereas the gating roles of the voltage-sensing and pore domains of kv channels have been extensively investigated, much less is known about the mechanisms governing the regulation of gating by the cytoplasmic t domain. previous work from this lab strongly suggests that the kv . t domain un- dergoes conformational changes directly linked to gating (j. gen. physiol., : - , ); however, the structural basis of the communication between the activation gate and the t domain has remained elusive. to tackle this problem, we applied cysteine scanning mutagenesis, voltage- clamp electrophysiology, double mutant cycle analysis (dmca) and oxidizing reagents to probe specific interactions between the cytoplasmic t domain l helix, the s -s linker and s tail. the energetic impact of the mutations on activation gating is apparently small. by comparison, the energetic impact of the mutations on inactivation gating was significantly greater. dmca of k c(l )þa c(s ) revealed a significant interaction energy ( kcal/ mol), which suggests an interaction between k in the l helix and a in s . supporting this possibility, the currents induced by k c(l )þ a c(s ) are inhibited (~ % of control) by an oxidizing agent (tbuho ), whereas the single mutants are not; and the effect is reversed by the reducing agent dtt. these results indicate the formation of a disulfide bond between the interacting side chains, which is consistent with physical interaction between k (l ) and a (s ). overall, we conclude that regulation of inactivation gating by the t domain involves a physical interaction between the t l helix and the distal segment of s . supported by nih grant r ns (mc). -pos board b is the activation gate closed in kv channel closed-state inactivation? jeffrey d. fineberg, manuel covarrubias. thomas jefferson university, philadelphia, pa, usa. kv .x channel complexes including auxiliary subunits such as dpp -s and kchip undergo preferential closed-state inactivation (csi; baehring and covarrubias, , j physiol, . : - ; fineberg et al., , j gen physiol, in press). however, the molecular basis of csi in kv .x channels remains poorly understood. a key unanswered question of this problem is whether the channel’s activation is actually closed, as csi implies. we have previously proposed that csi results when the activated channel fails to open or simply prefers to close. this hypothesis specifically suggests that the intra- cellular activation gate may adopt a stable closed conformation, even under depolarized conditions that would initially favor the activated ‘‘up’’ state of the voltage sensors. to test this hypothesis, we are exploiting the trapping paradigm previously investigated by holmgren et al. to test the state of the intracellular activation gate ( , j gen physiol, : - ). essentially, if the activation gate closes behind a quaternary ammonium (qa) blocker inside the pore, the blocker cannot exit the pore; effectively, it is trapped. we are expressing the ternary kv . /i c channels (this mutation favors trap- ping) including dpp -s and kchip in xenopus oocytes. then, in the inside- out patch-clamp configuration, we are using a computer-controlled perfusion system to deliver the qa derivative decyltrimethylammonium bromide (c ) to the bath and probe the ability of the channel’s activation gate to trap c in the closed, open and inactivated states. preliminary results show that the trapping paradigm may yield an answer to the central question of this study. if the activation gate is indeed closed during csi, c trapping will only occur when the drug is applied to the conducting channel, but no trapping of c will be observed in the closed and inactivated states. supported by nih grant r ns (mc). -pos board b water at the potassium channel gate: quantum calculations show an oscillation in water structure alisher m. kariev, michael e. green. city college of the city university of ny, new york, ny, usa. quantum calculations on the open gate and the immediately surrounding re- gion of the kv . voltage gated potassium channel show that water adopts two conformations there, one when the ion is present, and another with no ion present. an energy minimum at the gate with no ion allows an ion to enter from the solution; from the gate it repels an ion in the channel pore cavity into the selectivity filter (essentially the ‘‘knock-on’’ mechanism). the pore cavity minimum can then be occupied by the ion moving from the gate minimum, leaving it available for anion from bulk, so the cycle continues. the arrange- ment of water, and the ion hydration, defines the gate energy minimum, and this in turn depends on the highly conserved prolines, especially p ( a pdb numbering), in the pvpv sequence in the gate. absent an energy minimum at the gate an ion entering from solution would be repelled back into solution by the ion in the cavity. furthermore, the ion remains hydrated by water molecules, at least more than in bulk, as it passes through the gate, based on optimizations with the ion at three different positions: ) at the gate position nearest p ) å above ) å below, this position. the open gate maintains very nearly the same protein atom positions throughout. additional calculations will be required to determine the exact interaction en- ergy with an ion in the cavity, and the amount of water that is present in the cavity. optimizations of the system configuration were done at hf/ - gsp level, with atoms ( with the ion). energy was determined using both b lyp/ - g* and bvp / - g*, but the system was too large for free en- ergy determination. -pos board b water structure at the potassium channel gate: the importance of the prolines in the pvpv sequence, as shown by computational mutations, and the role of a histidine in gating alisher m. kariev, michael e. green. city college of the city university of ny, new york, ny, usa. conservation of the pvpv sequence at the potassium channel gate has not been well understood. quantum computations (optimization at hf/ - gsp level) of the gate of the kv . channel that are presented here show that the proline-proline distances (ring atoms) are preserved as the ion moves through the gate. this calculation is supplemented by mutating one of the prolines to valine (p v, a pdb numbering for all residues in this abstract) in the computation, producing a pvvv sequence. water structure changed dramati- cally, as the protein backbone moved inward nearly å, effectively closing the channel; the proline ring n-n distance between diagonally opposite pro- lines dropped from . å (distance from optimization: x-ray distance = . å) to . å, too small to allow passage of a hydrated k þ . this suggests that the prolines play a key structural role, modulating both protein and water structure. furthermore, protonation of h may close the channel. protonation of this histidine shows it moving toward the gate by about å, which should close the gate electrostatically, while deprotonation opens the gate. protonation was calculated with two added protons, the other being accepted by e of the t intracellular moiety. when deprotonated, the histidine does not move as much as å from the x-ray position in the optimization, and is linked to e ; this accounts for the known importance of the t segment in gating. e , also of t , could accept a third proton. there is a salt bridge structure including these residues similar to the one occupying a key position in the pro- ton pathway in the hv channel. access constraints and binding energetics of a potassium channel inactivation gate gating interactions between the cytoplasmic t domain and pore of a kv channel is the activation gate closed in kv channel closed-state inactivation? water at the potassium channel gate: quantum calculations show an oscillation in water structure water structure at the potassium channel gate: the importance of the prolines in the pvpv sequence, as shown by computation ... t h e american journal of international law volume published by t h e american society of international l a w publication o f f i c e : editorial and executive o f f i c e : t h e r u m f o r d p r e s s jackson place concord, n . h. washington, d . c. copyright, , by the american society of international law board of e d i t o r s of t h e a m e r i c a n journal of i n t e r n a t i o n a l law chandler p . anderson, new york, n . y. e d w i n m . borchard, yale law school. p h i l i p marshall brown, princeton university. e d w i n d. dickinson, university of california school of jurisprudence. charles g. f e n w i c k , bryn mawr college. james w. garner, university of illinois. m a n l e y o. hudson, harvard law school. charles c h e n e y h y d e , columbia university law school. p h i l i p c. j e s s u p , columbia university law school. arthur k. k u h n , new york, n . y. j e s s e s. r e e v e s , university of michigan. e l l e r y c. stowell, american university. l e s t e r h . woolsey, washington, d . c. quincy w r i g h t , university of chicago. honorary editor-in-chief james brown scott, washington, d . c. editor-in-chief george grafton w i l s o n , harvard university managing editor george a. f i n c h , jackson place, n . w., washington, d. c. the object of the american society or international law is to foster the study of international law and promote the establishment of international relations on the basis of law and justice. for this purpose it will cooperate with other societies in this and other countries having the same object. t h e american journal of international law is supplied to all members of the society without extra charge, as the membership fee of five dollars per annum includes the right to all issues of the journal published during the year for which the dues are paid.

pres- sure and peer review? television viewers in britain can make up their own minds this week when a unique combination of science and reality tv gets its first screening. billed as both entertainment and serious research, the bbc programme the experi- ment attempts to recreate aspects of a psychology study by stanford university researcher philip zimbardo. in the original study, volunteers were asked to assume the role of either prisoner or prison guard, and were placed together in a simulated jail. those acting as guards were so brutal to the prisoners that a shocked zimbardo abandoned the experiment and said that it should never be repeated. it is now seen as an important demonstration of how social circumstances can make people conform to particular roles. but whereas the stanford guards bullied the prisoners and forced them to clean toilets with their bare hands, their british counter- parts tried to befriend the prisoners and even agreed to reorganize the prison as a com- mune. an edited version of the -day trial, held last december at a london television studio, will be shown in four one-hour programmes beginning this week. “this has been a ground-breaking collab- oration between academia and the media,” says alex haslam, a psychologist at exeter university who planned the experiment with steve reicher, a researcher at the university of st andrews and joint editor of the british journal of social psychology. “it is not a media creation on which psychologists were invited to comment. the guiding principle for us and the bbc was always the science.” others warn, however, that it is difficult to compare the two studies directly, as behav- ioural trials are hard to replicate. the tele- vision cameras will also have had “an immedi- ate constraint on what people do”, says donald laming, a psychologist at the univer- sity of cambridge. zimbardo, still at stanford university, could not be reached for comment. for the experiment, male volunteers were recruited through newspaper adverts, and divided into guards and prisoners. the prisoners shared cramped cells and carried out chores, whereas the guards enjoyed better food and separate rooms and were given lim- ited powers over their charges. as well as observing and recording the behaviour of the volunteers, haslam and reicher asked them to complete psychometric tests and analysed their saliva for the stress hormone cortisol. it soon became clear that the guards were news nature | vol | may | www.nature.com unable to organize themselves. “there was a lack of a common social identity, no leader- ship and they didn’t even develop a simple shift pattern,” says reicher. the guards showed more psychological stress than the prisoners. haslam says that he welcomed the chance to challenge the stanford results, and claims that the guards who behaved as tyrants in the original experiment did so only because they were encouraged to. n reality tv show recreates famed social study broadcasting behind bars: the experiment aims to explore how people conform to set roles. jefferson’s descendants continue to deny slave link erika check, washington thomas jefferson’s descendants have decided that the ancestors of one of his slaves cannot join their family club, despite dna evidence published in nature suggesting that he fathered at least one of her children. the monticello association, a group of nearly descendants of jefferson’s daughters, voted on may to keep sally hemings’s descendants out of their group. this means that hemings’s relatives cannot be buried in the graveyard at monticello, jefferson’s home in charlottesville, virginia. their vote is the latest twist in a racially charged controversy that has raged since jefferson’s own day, when it was noted that sally hemings’s children bore a likeness to the third president. that and other evidence fuelled speculation that the author of the declaration of independence fathered six children by hemings, who was a slave at monticello. she only became pregnant during times when jefferson stayed there. jefferson’s descendants have always disputed this speculation. jefferson’s grand- children claimed that one of his maternal nephews, samuel or peter carr, fathered hemings’s children. but genetic tests pub- lished in november (see nature , – ; ) eliminated that possibility. the tests compared the y chromosomes of men descended from sally hemings’s son eston with those from the jefferson and carr family lines. eston’s y chromosome was found to be virtually identical to jefferson’s and dissimilar to the carr chromosome. the study caused an outcry because it was published in the midst of then-president bill clinton’s impeachment process. clinton’s supporters seized on it as proof that previous presidents — even the most celebrated ones — had also engaged in sexual indiscretion. the findings prompted the thomas jefferson foundation, which owns and operates monticello, to investigate the hemings connection. in january , it concluded that the dna study, combined with other evidence, indicated a “high prob- ability that thomas jefferson fathered eston hemings, and that he most likely was the father of all six of sally hemings’s children”. but jefferson’s descendants remain unswayed, and now say that thomas’s brother randolph was probably eston’s father. “they have not provided conclusive evidence that thomas jefferson had a relationship with sally hemings,” says nathaniel abeles, the monticello association’s president. the association’s position cuts no ice with the academic community. “this decision is scientifically unsound, historically unsound and morally bankrupt,” says annette gordon-reed of the new york law school. “the issue is pretty much settled and the fact that the family association chooses to tell a story about itself doesn’t affect what scientists or historians think.” n b b c monticello, home of thomas jefferson, where his

probably the current agent of choice for bone imaging, and satisfactory renal imaging can be obtained during whole.body bone scanning because the kidneys excrete s mtc.polypho ph@ge. in our ex perience, renal images noted during bone scan ning with somtc@polyphosphate are of diagnostic quality. technetium- m-polyphosphate has recently been introduced as a bone scanning agent ( — ), and it is probably the current agent of choice for bone imag ing. the localization of damtc@polyphosphate in the skeletal system is similar to other bone-seeking radio nuclides, and — % of the administered dose was localized in the skeleton of normal rabbits ( ). the mode of excretion is through the urinary tract, thus affording excellent images of the kidneys at the time of bone scanning. recently patients undergoing ddmtc@polyphosphate bone scanning at our institution were noted to have abnormal renal images. these abnormalities were confirmed, thus suggesting that renal lesions may be accurately imaged during bone scanning with this agent. methods technetium- m-polyphosphate is prepared from a sterile, pyrogen-free kit manufactured by diagnos tic isotopes inc. and new england

% ( ) . usually, renal radioactivity would not interfere with the skeletal imaging of the lumbar spine. however, it is very difficult to interpret the pelvic areas when the urinary bladder is filled

radiation dose to the kidneys is mrads per mci @'tc-polyphosphate assuming % of an injected dose in the kidneys and renal disappearance by physical decay alone ( ). to decrease radiation dose to the kidneys and bladder, hydration, and fre quent voiding are recommended to the patient. acknowledgments we thank joan franco for technical assistance, and mary ellen martin and jane russel for

scientific affairs, llc, titusville, nj, usa objective: to compare the impact of topiramate mg/day versus placebo on workplace productivity among individuals with migraine, using data from two six-month randomized, double-blind trials. methods: a five-item survey for each migraine attack captured the participants’ number of hours absent from work (“absenteeism”, a), number of hours worked with migraine (wm), and degree of effectiveness (e) while working with migraine. presenteeism (p) was calculated as the product of wm and e. total lost productivity was the sum of a and p. the mean monthly ( -day) rate of lost productivity per person at baseline and double-blind periods was compared between the study arms using wilcoxon rank sum tests. results: a total of subjects were enrolled in the trials ( topiramate, placebo). of these, subjects reported any lost productivity at baseline ( topiramate, placebo). mean ± sd age was ± years, . % were female, and . % were caucasian. demographic characteristics were similar between groups. the most common adverse events for topiramate in the clinical trials included paresthesia, nausea, anorexia, and fatigue. at baseline, the mean rates of total lost productivity were . hours/ days for topiramate mg/d and . hours/ days for placebo (not significant). total lost productivity hours/ days for topiramate mg/d versus placebo were .

placebo were sta- tistically significant (p < . ) in months , , , , and . con- clusions: this is one of the first studies examining the impact of topiramate on workplace productivity, based on post-hoc analysis of randomized trials. our findings suggest that topira- mate mg/day may be associated with improvements in pro- ductivity among individuals with migraine. in memoriam: jim cathey

every so often how we spent it. did we do enough good for the family and for the wider community to which we belong? in answering this question, we should adjust our trajectory in this world, for as long and as much as we can, based on virtue and talent, as thomas jefferson would say if he were still here with us. if aristotle was right in defining happiness as “when you can develop freely your predominant talent,” then jim cathey was happy. jim joined the faculty at university of kentucky decades ago, when i was there as a visiting scholar. coming from industry, jim had remarkable practical electrical engineering abilities, and all students who had electric machinery labs or design courses with him would testify to this. he was a devoted and passionate teacher. although he had many published papers, jim did not follow the crowd, and his published work was thorough and practical. his textbook on electric machinery is an excellent demonstra- tion of teaching talent: depth, balance, clarity, practicality, and impeccably worked-out numerical examples. more than a decade ago, jim took over this journal from its founding editor, professor syed a. nasar. since then, the review process has been streamlined and an on-line process implemented, with the number of papers published per year more than doubling. this all took time and effort, but jim was patient and hardworking, and he did it with diligence as a service to the worldwide electrical engineering community. for all of this and much else, the community is most grateful to jim. occasionally, during my many visits to university of kentucky, jim invited me to lunch and we discussed matters of education and life. jim was a religious man. miguel de unamuno, the great spanish writer and philosopher, asked himself in his “personal in memoriam: jim cathey journal” whether, in order to be religious, one had to be good first or if it was the other way around. well, jim was both. his ph.d. students, who are now well accomplished in life, will tell you about his goodness and dedication to them. jim enjoyed working afternoons and had a special sense of texan humor; his office door read “nothing makes sense before noon.” jim was a quiet and practical engineer, teacher, and researcher who combined hard work and modesty to serve our community in kentucky and around the globe through electric power components and systems. he did his share with dignity and honor, and we should always remember and praise his memory. professor ion g. boldea, ph.d., ieee life fellow founding member of the

cardiovascular disease left ventricular hypertrophy (lvh) g protein–coupled receptor kinase (grk ); guanine nucleotide binding protein, q polypeptide (gnaq; gq); histone deacetylase (hdac ); myocyte enhancing factor (mef ; d-mef ) studies in mice and in cell culture suggest that targeting grk could help treat lvh associated with heart failure. in mouse models of pressure- overload cardiac stress, grk overexpression led to cardiac hypertrophy and increased the incidence of heart failure compared with what was seen in wild-type mice or mice that overexpressed a grk variant that did not enter the nucleus. in vitro, cardiac stress–induced g protein–coupled receptor signaling led to upregulation of grk and its subsequent translocation to the nucleus, where it induced hdac -mediated expression of hypertrophy genes. ongoing studies will assess the specificity of grk ’s activation of hdac and the effects of targeting grk with a grk -specific microrna. many companies market or are developing compounds to treat or prevent hypertrophy via treatment of hypertension and/or ischemia, two conditions that can lead to lvh and subsequent heart failure. not patented; licensing status undisclosed

modification april /accepted august we evaluated the strep b optical immunoassay (oia; thermobiostar, inc.) for detecting light and heavy group b streptococcus colonization in , pregnant women. the women were examined at to weeks gestation and were from six countries. compared to culture, the sensitivity and specificity of oia were . and . %, respectively, for light colonization and . and . %, respectively, for heavy colonization. heavy colonization with group b streptococcus (gbs) may place women at high risk of delivering preterm, low-birth- weight infants ( , , ). earlier recognition of such high-risk women would be useful for intervention strategies. detection of heavy colonization has traditionally relied on culture meth- ods, which may not be feasible in some health care settings and require to days before results are available. unfortunately, most rapid gbs tests have poor sensitivity ( , ). the strep b optical immunoassay (oia; thermobiostar, inc., louisville, colo.) is a rapid method which may have higher sensitivity for dense gbs colonization ( ). we evaluated the performance of this test in an international, multicenter study. we conducted the study at institutions participating in the global network for perinatal and reproductive health (http: //www.tju.edu/obgyn/rih/global.cfm). centers were located in khon kaen and bangkok, thailand; manila, the philippines; harare, zimbabwe; yangon, myanmar; dublin, ireland; and philadelphia, pennsylvania. participants were enrolled in the study between june and may . women attending prenatal care clinics and at to weeks gestation were eligible. exclusion criteria included vaginitis symptoms, fever, vaginal bleeding, multiple pregnancy, use of antibiotics in the past weeks, and active labor. informed consent was obtained. the study was approved by institutional review boards at all study centers and supporting institutions. at enrollment, study personnel conducted an interview and collected specimens. a sample for gbs rapid testing was col- lected from the cervix and lower vagina using a thermobiostar swab. oias were read by study site laboratory personnel and by the manufacturer’s laboratory personnel. oia kits and swabs were supplied by thermobiostar. methods for gbs culture and quantitation replicated those used in the vaginal infections and prematurity study ( ). after collection of the oia specimen, a dacron swab (copan swab) was used to collect a specimen from the cervix and lower vagina. samples were streaked onto blood agar plates using the four-quadrant method and then placed into lim broth (todd- hewitt broth containing selective antimicrobial agents). a clean catch urine specimen was collected for gbs culture on blood agar. suspect colonies showing �-hemolysis were iden- tified as gbs using latex agglutination. heavy colonization was defined as isolation of gbs from either urine or direct plating on blood agar. light colonization was defined as isolation of gbs from lim broth alone. dense gbs colonization was de- fined as growth in the third or fourth quadrant streaked on the blood agar plate ( ). data were entered by using epi-info version ( ) and trans- mitted to the centers for disease control and prevention monthly. we calculated the sensitivity, specificity, positive pre- dictive value, and negative predictive value of the oia using culture results as the “gold standard.” the chi-square test was used to compare the results of oia readings done by the manufacturer’s staff versus the readings done by study center personnel. we enrolled , women; their mean age was . years, and the mean gestational age was . weeks. gbs coloniza- tion was the highest in philadelphia, pa., ( . %) and lowest in yangon, myanmar ( . %). the rate of gbs isolation was higher from lim broth culture than from other methods (table ). compared to culture, the sensitivity of oia for detecting * corresponding author. mailing address: department of

to . % ( % ci, . to . %) in philadelphia, pa. oia sensitivity was . % for lightly colonized women, . % for heavily colonized women, and . % for densely colonized women (table ). oia sen- sitivity and specificity were . and . %, respectively, com- pared with culture on blood agar and . and . % com- pared with lim broth. the oia was positive in . % of women who were negative by all culture methods. oia test readings performed by the manufacturer and by study site personnel were similar (kappa of . ); the sensitivities from study site personnel and manufacturer readings was . % ( % ci, . to . %) and . % ( % ci, . to . %), respectively. our study demonstrated that the sensitivity of oia to detect gbs colonization compared with that of culture was low, al- though the sensitivity of oia in detecting heavy or dense colonization was higher than its sensitivity for detecting light colonization. our findings confirm earlier work that found reliance on blood agar alone was insensitive for detecting light colonization and that comparing rapid detection methods with blood agar alone falsely elevated the sensitivity of these tests. enrichment broth media, such as lim broth, enhance gbs growth while suppressing growth of other bacteria, thus im- proving identification in specimens with low bacterial inoculum ( , ). in previous studies, the performance of the oia has been compared with selective broth media. the specificity was uni- formly high, to %, similar to the . % in our study. conversely, previously reported test sensitivities varied widely but were generally higher ( to %) ( , , , – , – ) than the value we found ( . %). the most important reason for this variability may be the extent to which the subjects were colonized. the sensitivity of the oia has been higher ( to %) when compared with third- and fourth-quadrant posi- tive blood agar cultures ( , , , – ). our finding was within this range ( . %). our study had limitations, as it did not evaluate the perfor- mance of the oia to weeks before delivery or at delivery, when it would have the most clinical value ( ). however, the average gestational age for our participants was . weeks, a time when the fetus is considered viable in many centers, making our data potentially useful for evaluating the role of gbs in preterm birth. we did not collect specimens from the rectum; collecting both rectal and vaginal cultures increases the detection of gbs carriage in pregnant women ( ). if we had collected rectal specimens, we would have identified more gbs carriers, and the oia performance would have been worse. in conclusion, the low sensitivity of the strep b oia may limit its usefulness for detecting gbs in pregnant women, although the best performance of the test is in women who are heavily colonized and who therefore may be at highest risk for complications due to gbs infection. new tests, such as the newly licensed pcr test, may provide other options ( ). for now, culture of specimens from the rectum and lower vagina remain the gold standard for detecting gbs colonization in pregnant women ( ). this project was performed with the financial support of the rock- efeller foundation;

novartis) achieved a progression-free survival (pfs) period of . months compared with . months for patients who were treated with letrozole alone. “this was a welcome result,” commented norman sharpless, md, deputy director of the lineberger comprehensive cancer center at the university of north caro- lina (unc) at chapel hill, who was not associated with the study. “a tripling of pfs in this disease is a great fi nding.” cdks, which participate in cell prolif- eration, tend to be overactive in cancer. richard finn, md, associate professor of medicine at the jonsson comprehensive cancer center at the university of california, los angeles, and the study’s principal investigator, explained that the primary function of cdk / is to phosphorylate the retinoblastoma (rb) protein, which ordinarily blocks early events in the cell cycle. phosphorylation inactivates rb so that cells can continue to divide. in some cancers, however, cdk / hypherphosphorylates rb, which can lead to uncontrolled cell growth. by inhibiting cdk / , pfi zer’s experi- mental drug prevents rb hyperphos- phorylation. moreover, finn added, it has minimal side effects. according to finn, preclinical stud- ies indicate that only er-positive breast cancer cells had robust responses to pd- . “er positivity appears to be a marker for an intact rb pathway,” he said. that’s noteworthy, unc’s sharp- less added, given that rb loss occurs in roughly % of all cancers. “the drug won’t work in patients who lack the rb pathway,” he noted, “so that gives us a good negative biomarker for who won’t respond to treatment. what we need now is a better posi- tive biomarker to identify those who might respond best in breast cancer and other cancer types.” ■ surveillance network aids prostate research up to % of men diagnosed with prostate cancer have a form of the disease that grows so slowly that it’s unlikely to ever threaten their health if left untreated. unfortunately, physicians currently have no precise way to determine which patients can forego treatment. “we need to fi nd out whether a tumor is a wolf in sheep’s clothing or if it’s really a sheep,” says stuart holden, md, director of cedars-sinai’s louis warschaw prostate cancer center in los angeles, ca, and medical director for the prostate cancer foundation, a philanthropic organization that funds research on the disease. thanks to a $ -million grant from the foundation, researchers from johns hopkins medicine in baltimore, md, and colleagues at cedars-sinai have launched the national proactive surveil- lance network (npsn), a repository of patient information that will advance understanding of who needs treatment. patients at the institutions who are diagnosed with early-stage, low-volume prostate cancer will be invited to join the program; other institutions will be added to the network in mid- to late . patients pursuing proactive surveil- lance defer treatments such as surgery and radiation therapy. instead, they are closely monitored with physical exams and medical tests every months and a prostate biopsy every year. if cancer progresses, they may opt for treat- ment. this strategy is also called active surveillance, expectant management, or watchful waiting. participants regularly complete detailed lifestyle and nutrition ques- tionnaires, and their blood and urine samples and biopsy tissue are banked people glenn dranoff, md, a professor of medicine at dana- farber cancer institute and harvard medical school in boston, ma, has been named the founding editor-in-chief of cancer immunology research. published by the american association for cancer research, the journal will launch online at the organiza- tion’s annual meeting in april, followed by monthly print issues beginning in june. the leader of the dana-farber/ harvard cancer center program in cancer immunology, dranoff has devoted his research efforts to under- standing tumor immunity and to the development of cancer vaccines. karen e. knudsen, phd, began a -year term as editor-in-chief of molecular cancer research this month. she succeeds michael b. kastan, md, phd, executive director of the duke cancer institute in durham, nc. knudsen is a professor in the depart- ments of cancer biology, urology, and radiation oncology at philadelphia’s thomas jefferson university and deputy director for basic science at the affili- ated kimmel cancer center. in addition to authoring book chapters and dozens of peer-reviewed articles, she has held several leadership roles on scientific publications, including cancer research. richard nakamura, phd, has been chosen as the new director of the nih’s center for scientific review (csr). he will lead scientists and administrative staff, overseeing their efforts to manage , nih grant applications a year, the majority of which are reviewed by csr peer review groups. the csr holds , review meetings a year. prior to joining the csr in , nakamura spent years at the national institute of mental health, serving as both its scientific and deputy director. c e n te r fo r s c ie n ti fi c r e v ie w on april , . © american association for cancer research. cancerdiscovery.aacrjournals.org downloaded from published onlinefirst december , ;

border scouts and spies, simon kenton, samuel brady, and lewis wetzel; the conqueror of the old northwest, george rogers clark; the "gamecock of south carolina," thomas sumter; the courageous mohawk chief, joseph brant; the distinguished shawnee warrior and statesman, tecumseh; and their many associates, friends and foes. from this plan draper never departed. in accordance with his aim he gathered the thousands of papers that constitute the draper collection of manuscripts, bequeathed by him to the state historical society of wisconsin at his death. before he became in the first director of the society, a posi- tion to which he devoted most of his time and energy until his re- tirement years later, he had acquired the most significant por- tions of his collection, including nearly all of the original records that it contains. in he estimated that his collection comprised "some , foolscap pages of notes of the recollections of warri- or-pioneers, either written by themselves, or taken down from their own lips; and well nigh , pages more of original manuscript journals, memorandum books, and old letters written by nearly all the leading border heroes of the west." many of these papers he had acquired by extensive travels in the 's through many of the states in the eastern and southern sec- tions of the country. journeying sometimes by wagon, by stage, by boat, or by train, but frequently on foot, he eagerly interviewed pioneers and their descendants, unearthed long forgotten records, and copied the manuscripts, newspapers, and printed documents of which he could not obtain the originals. although not so pro- ductive of original manuscripts as were his earlier ventures, his several other excursions into the south after yielded addi- tional papers. after his days of research trips were over, he could claim that his collection was "the systematic result of over years labors & , miles of journeyings — ." whatever discomforts he endured in his travel were more than compensated for by his lyman c. draper, circular letter, may i, . draper to charles mcknight, february , . d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . . n q g by c arnegie m ellon u niversity user on a pril lyman c. draper and early archives elation at the discovery or acquisition of a valuable group of manu- scripts or notes. during one southern tour he particularly rejoiced at the finding of the papers of william fleming, commander of the botetourt regiment at the battle of point pleasant, which had lain untouched but well preserved for nearly years after flem- ing's death.* a few days later he examined " or bushels" of papers of william cocke, revolutionary militia captain near the present boundary of virginia and tennessee, but these had so de- teriorated that draper had difficulty in deciphering the parts he wished to copy. when traveling, he worked assiduously at collect- ing, arranging, and transcribing, "seldom going to bed before or at night, & up early & at it before breakfast — ." "it hasn't been a play-spell," he exclaimed after spending each day from o'clock in the morning until sundown copying documents in the new york state library for nearly weeks during november . on his research trips he utilized not only papers in private owner- ship but also those in existing federal and state archives in the united states and in canada. from the canadian archives he ac- quired copies of papers of daniel claus, sir william johnson, george clinton, and philippe de rocheblave. additional papers of johnson and clinton, as well as transcripts of documents in lon- don and paris, he copied at the new york state library at albany. at harrisburg he searched the pennsylvania archives for material on the revolution in the upper ohio river valley; at richmond he found material pertaining to virginia and neighboring regions. in washington he spent a total of many weeks transcribing excerpts from the records of the continental congress, from the correspond- ence of washington and jefferson in the state department, and from the military papers of william henry harrison in the war department. at the pension office he copied hundreds of state- ments of military service filed by aged revolutionary war veterans. he also visited courthouses in north carolina, virginia, kentucky, and tennessee to obtain copies of selected county records. moreover, in the period and area that draper had chosen to study, the trans-allegheny west from approximately to , the dividing line between government archives and private manu- scripts may sometimes seem almost indistinguishable. because few archival depositories were then organized in north america and draper to peter a. remsen, august , . b draper to remsen, august , . draper to remsen, august , . draper to remsen, november , . d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . . n q g by c arnegie m ellon u niversity user on a pril ao the american archivist because many of the western militia units in the revolutionary war and in indian border warfare were largely composed of citizen vol- unteers, the officers frequently retained their correspondence and military records among their personal papers. because draper him- self conceived the history of western expansion to be primarily in terms of military events and of the actions of heroic pioneers, many of whom were soldiers, he attempted to gather the surviving papers of as many of these men as possible. in the draper collection, there- fore, are manuscripts, usually military in nature, that might per- haps have been found in state and national archives if more such agencies had been organized in the eighteenth and nineteenth cen- turies. for the colonial period draper found but few original papers. these include, among the papers of william preston, the corre- spondence, muster rolls, receipts for pay and provisions, and court- martial records for the militia of augusta county, virginia, in the period from to . a few military records for other coun- ties of virginia and pennsylvania during the french and indian war may also be found in the papers of evan shelby and of james potter. scattered elsewhere in the collection are petitions to wil- liam tryon, royal governor of north carolina, and a few letters and land warrants written by lord dunmore, royal governor of virginia. most of the original manuscripts in the draper collection relate to the quarter-century from to , marked by the revolu- tionary war and by hostile disturbances with the indians on the frontiers of american settlement. draper gathered the extant pa- pers of many of the western military leaders for this period. the largest in number as well as perhaps the most notable are the pa- pers of george rogers clark. later bound together with draper's notes and correspondence about clark into large folio volumes, these include much of clark's official incoming correspondence from his officers and military associates, drafts of many of his own let- ters, records of his famous illinois regiment, and some captured british correspondence and documents of henry hamilton. draper acquired also the papers of several other leaders: william preston, organizer of the expedition under andrew lewis which repelled the indians at point pleasant in and participant in the negotia- tions with the cherokee indians in - ;

included are militia orders, muster rolls, pay rolls, and accounts for food, lodging, clothing, and horses, as well as a wealth of correspondence from many of the officers who served along the frontiers from pennsyl- vania to the carolinas and westward to the illinois country. much less numerous in the draper collection are records of the war of . they include a book of general orders kept by an- drew jackson's command from october to december and several small groups of papers of other participants: james win- chester, commander of the troops defeated at the river raisin in ; benjamin whiteman, a general of the ohio militia; nathan heald, commanding officer at fort dearborn until captured there in ; and martin d. hardin, major in the kentucky militia serving under william henry harrison. the papers of thomas forsyth, indian subagent for the sauk and fox indians near peoria, illinois, contain a number of official letters from william clark, governor of missouri territory and superintendent of indian af- fairs at st. louis, and from ninian edwards, territorial governor of illinois. in the draper collection records of officials of civil government may be found; but frequently, as in the case of the letters of gov- ernors edwards and clark, the papers pertain mainly to warfare, so closely were frontier military and civil affairs interwoven by troubles with the british and with the indians. besides clark and edwards, the executives of several other states and territories are represented by correspondence in the collection: george clinton of new york; patrick henry, thomas jefferson, edmund randolph, and henry lee of virginia; william blount, john sevier, and wil- lie blount of tennessee; isaac shelby of kentucky; and edward tiffin and thomas kirker of ohio. of these the papers of thomas jefferson are among the most numerous and most interesting, total- ing original letters and signed documents, in addition to con- temporary copies of several other letters. most of these are among the george rogers clark papers, although jefferson's correspond- ents included a number of other border leaders besides clark — d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . . n q g by c arnegie m ellon u niversity user on a pril io the american archivist evan shelby, joseph martin, john todd, thomas walker, wil- liam preston, david shepherd, daniel smith, and joseph crockett. a dozen letters, dated from to , from henry knox, sec- retary of war, were addressed to david shepherd and are pre- served among his papers, as is also one letter from president wash- ington concerning a land claim. original records of county officers number only a very few pieces: an account of sheriff's fees kept for botetourt county, virginia, in ; several official papers, - , of john potter, sheriff of cumberland county, virginia; and a small group of documents kept by robert patterson as sheriff of fayette county, kentucky, in - , and as justice of the peace during - . aside from a few periodical articles and one large volume, king's mountain and its heroes, published in , draper's dream of writing a series of books on the history of the early west never materialized. his work as the successful organizer and promoter of the state historical society of wisconsin left him little time for personal research and writing. he was further hampered by an ex- aggerated fear that he would produce books which might contain errors in detail or prove incomplete in some small respect. "i w[oul]d sooner starve, or very nearly so, than suffer anything to go out in a shiftless and imperfect manner," he once declared after many years of study. draper urged the construction of a fireproof building for the library of the wisconsin historical society. he recognized that manuscripts are perishable, and that "important historical facts, narratives and documents are lost every year for want of proper foresight and care for their preservation." yet, in handling his own collection, draper did not share the insistence of the modern archivist or manuscript specialist upon orderly arrangement and special treatment for aged and fragile papers. the vast number of manuscripts he had acquired seemed to make their organization too overwhelming a task for his meager spare time after he came to wisconsin. nevertheless, he could not refrain from continuing to augment his collection by additional correspondence on minute de- tails. even the fleming papers, which he had gathered in , were unarranged more than years later. by that time ( ) he had had about volumes of manuscripts bound in accordance with draper to mcknight, february , . draper to george grimmer, september , . sixteenth annual report of the executive committee, , wisconsin historical collections, vi, p. . d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . . n q g by c arnegie m ellon u niversity user on a pril lyman c. draper and early archives the library practice of that time. he estimated that papers to fill another or volumes were nearly ready for the bindery, and the remaining material he believed would probably comprise be- tween and more volumes. when the state historical so- ciety received the collection years later, very few additional man- uscripts had been arranged or bound. draper kept his personal li- brary in a brick building to the rear of his madison residence. there the papers were somewhat safeguarded against the danger of fire. after the great collector's death in , however, it was discovered that the building was damp and infested with rodents, and that the unbound manuscripts were in a discouraging state of chaotic disorder. the collection was soon moved to the state historical society, where the loose papers were studied, sorted, and bound to conform as closely as possible to draper's intended scheme of arrangement whenever this could be discerned. as finally com- pleted, the draper collection numbers volumes divided among series or subcollections, most of which are grouped around an . individual, a subject, or a geographical area about which draper had planned to write. the manuscripts, both originals and copies, have proved to be a mine of valuable information for hundreds of authors and re- searchers since the draper collection was opened to public use nearly years ago. the importance of the records in transcript should not be underestimated, for in many cases the originals that draper copied have since been lost, dispersed, or destroyed by fire or war. even small excerpts from county archives have been grate- fully perused by later historians. in some instances, of course, the publications of state archives, such as those of virginia, pennsyl- vania, and other states, have superseded draper's copies. the pa- pers of josiah harmar, from which harmar's descendants per- mitted draper to make selected copies, have been fortunately ac- quired in the twentieth century by the william l. clements library. yet numerous articles, histories, and biographies of such figures as george rogers clark, william clark and meriwether lewis, daniel boone, james harrod, and william croghan, have been based in large measure upon the draper manuscripts. countless military records and pieces of correspondence have been printed, some as individual items, some in collections of documents, some in historical and genealogical periodicals. to cite only two rather draper to mcknight, february i , . wisconsin historical society, proceedings ( th annual meeting), , pp. - ;

family history; pancreatic cancer; risk factors; quality of life introduction population-based cancer registries were first estab- lished in europe and north america in the s and s to generate statistics on the incidence of can- cer in a defined population. the essential variables to be recorded by cancer registries include personal iden- tification, gender, date of birth, address, ethnic group, incidence date, site of cancer, histology, tumor behav- ior (benign or malignant), and the source of informa- tion. recommended or desirable additional variables are date of last contact, survival status, stage at diagno- sis, and treatment. there are numerous types of can- cer registries including those that are nationally, state, and regionally mandated;

( ) to provide a link between gene mutations, family history, and precision medicine therapy (in conjunction with the ongoing jefferson tissue banking study); and ( ) to identify high-risk nonaffected family members (nafms) for potential surveillance screening. information on sociodemographic background, lifestyle factors, fam- ily history of any cancers, known inherited genetic syndromes, longest-held occupation, and known environmental risk factors, including tobacco exposure and industrial carcinogens, is collected through a self- administered questionnaire and entered into a password- protected access database maintained by the jptr co-director and the coordinator. the questionnaire may be accessed either directly from a co-investigator at our institution or through the dos website. data for analysis are collected through hard copies of jptr ques- tionnaires, electronic medical record, operative notes, molecular analysis, and pathology reports. family geno- grams are created using progeny � software. all persons with known or presumed pc and related cancers and premalignant lesions, who are years of age or older, are eligible to participate. nafms of the index case are encouraged to enroll as well and serve as a control group. both groups must provide written informed consent before completing the questionnaire. recruitment for the registry may occur at an initial out- patient consultation, after surgery, through the dos website, or at specialized patient symposiums at our institution. registrants are provided with printed in- formation on the registry and given the questionnaire, which can be returned through mail in a self-addressed stamped envelope. several jefferson-affiliated irb hos- pital sites in pa and new jersey also enroll a limited number of patients with pc at their facilities. these patients have typically received either chemotherapy or radiation therapy (rt) at that institution but have not had surgery there. jptr registrants are classified as either (a) familial pancreatic cancer (fpc) (defined as one or more first degree relative with pc in addi- tion to the index case), (b) sporadic pancreatic cancer (spc) (index case only has pc), which is consistent with other established cancer registries, or (c) control group, (defined as nafms). it should be noted that the control group is dynamic in that members may later be diagnosed with either fpc or spc and reclassified as necessary. annual follow-up of jptr registrants is conducted by three methods: ( ) an annual update is mailed di- rectly to all registrants or to a designated relative or next-of-kin. the update inquires about current health conditions, the recurrence of pc, or the development of other cancers or medical conditions in the index case, registrant, and in other family members, and ( ) a unique specialized survivor survey is mailed to those registrants presumed to be living. this survey includes probing questions on quality-of-life issues, ongoing disease, or postsurgery complications, and individual reflections on treatment decision-making, and ( ) the survivorship status of the cohort is documented through the use of internet searches for published obituaries, re- ports on the annual surveys, and by families notifying us directly by letter, e-mail, or phone call of a death. our newsletter, the jefferson pancreas tumor regis- try update, is published each year and is mailed to all registrants and to all listed contact persons. the news- letter is a benefit to those enrolled and features an uplifting survivor story and provides an update on the current status and results of ongoing pc research stud- ies at jefferson. in addition, the newsletter serves as a venue to report on the annual sidney kimmel cancer center jefferson pancreas cancer and related diseases yeo, et al.; journal of pancreatic cancer , . http://online.liebertpub.com/doi/ . /pancan. . symposium and to display the annual pc survivor group photo. the symposium, held every november (pancreas cancer awareness month), was initiated by the dos in as a community outreach effort for pc and related cancer survivors, their families, and interested community members. over the past years, it has grown in magnitude, focus, and influ- ence. it is a highly anticipated event with well > at- tendees. the complimentary program features a gastrointestinal-friendly breakfast followed by short re- ports on the current state-of-the-science in pancreas cancer research at jefferson and interesting clinical topics. the symposium is unique and likely the largest of its kind in the united states. these activities contrib- ute to an enhanced feeling of community for pc survi- vors and their loved ones. attendees receive a mailing from the thomas jefferson university office of institu- tional advancement and many make a contribution to support pancreas cancer research. results demographics since , * % of eligible patients at tjuh have been recruited to participate in the jptr. seven hun- dred eighty-four individuals have enrolled in the jptr, of which have mostly complete and useable information. the majority of registrants ( %) have spc, % are fpc cases, nafms (controls) constitute %, and the remaining % have other biliary condi- tions or nonpancreas cancers. (selected clinical charac- teristics of the cohort are shown in table ). ninety-two fpc cases were identified by defining fpc as the index case plus one first-degree family member with pc. using a more stringent definition of family history as the index case plus two first-degree family members and at least one second-degree relative with pc, ( %) cases were identified. thirty-six ( %) of the fpc cases also reported between three and seven other types of cancers in their first- or second-degree relatives. there was one fpc case who had a family history of hereditary pancreatitis, other- wise no high-risk familial syndromes were identified. genetic testing for specific gene mutations was not conducted. the characteristics of fpc cases and con- tributory risk factors for pc are shown in table . cig- arette smoking was reported by % of the fpc cases, attesting to the synergistic effect of smoking and a familial history of pc. as reported by schenk, a family history of pc or ever-smoking cigarettes doubles one’s risk of developing pc (relative risk . ), and for current smokers who were also related to someone with pc, the relative risk of pc jumped to . . the demographic background of the jptr is consis- tent with other published pc registry data, , although they differ somewhat from nationally published statis- tics in that the median age of those enrolled is years, the sample is % white, % african american, % asian or hispanic, and % of unknown race or eth- nicity. men ( %) and women ( %) have near equal representation. almost half of the cohort ( %) were either current or former cigarette smokers. twenty- eight percent of the registrants had diabetes at the time of enrollment. studies have shown that new onset of diabetes in persons years of age or older, coupled with weight loss and long-term smoking, should raise the index of suspicion by primary care clinicians about an underlying cancer and warrant screening by magnetic table . – jefferson pancreas tumor registry registrant characteristics (n = ), n (%) sporadic pc ( %) familial pc ( %) controls (nafms) ( %) related conditions ( %) high-risk nafms ( %) gender: women % median age: (range – years) race: white % african american % asian, hispanic % unknown % ashkenazi heritage: mother ( %) father ( %) both parents ( %) smoking (current or former) / ( %) diabetes / ( %) top exposures: asbestos / ( %) pesticides/herbicides / ( %) residential radon / ( %) heavy wood dust / ( %) related conditions: duodenal cancer, bile duct cancer, ipmns, pancreati- tis, cysts. denominators vary based on number that answered the question. pc, pancreatic cancer;

(this requires that patients under- going surgery at tjuh have given consent for both studies.) a recent article by our laboratory described a correlation between a functional snp in an immune regulator gene encoding the enzyme indoleamine- , - dioxygenase- (known as ido ) and the risk of fpc. pcr amplification of dna extracted from resected spec- imens stored and annotated in our biobank was used to identify a wild-type, heterozygous, and a homozygous ido genotype, which has been previously shown to correlate with decreased enzymatic functionality. , in this preliminary, single-institution study, the homo- zygous genotype (ido ) was associated with an in- creased risk of fpc as compared with a control group. we also identified snps (insertions and deletions [indels]) embedded within the ¢utr of the mitotic kinase checkpoint inhibitor gene, wee .* this site is a previously published hur binding site. tumor samples from resected patients with pancreatic ductal adenocarci- noma in the fpc group from the jptr were analyzed using standard gene amplification techniques to identify wild-type, heterozygous, and homozygous wee allelic alterations. index pc cases with the t allele were sig- nificantly more likely to have first-degree relatives with lynch-type cancers (colorectal, endometrial, gastric, and ovarian) as compared with cases without a family history of these cancers.* both the ido and the wee snps may have significant implications for screen- ing high-risk individuals and may also have value as a predictive marker for therapy using novel immune checkpoint inhibitors or dna damaging therapies. decision counseling recruitment to cancer registries can be challenging in the era of internet access due to fears of confidentiality. thus in , the jptr served as the setting for a study designed to assess the impact of the decision counsel- ing program� (dcp), a shared decision-making soft- ware program, on recruitment to the jptr. the study was the first to evaluate the impact of a dcp specifi- cally on the registry enrollment of patients with pan- creas cancer. meyers et al. found that % of pc patients who received in-person decision counseling enrolled in the jptr as compared with only % of pc patients who had telephone counseling. altruism was the most frequently cited motivating factor for par- ticipating by both those who enrolled and those who did not enroll. this study added to the literature on cancer registries by identifying obstacles that led to the decision to decline enrollment in the jptr: that is, the complexity of the registration process, feeling overwhelmed by the process of recovering from surgery, and worry about the confidentiality of their information. *brown et al., ‘‘identifying a sequence alteration in the regulatory domain of cell cycle inhibitor, wee , could define a novel familial, lynch-like syndrome and have implications for the treatment of pancreatic cancer,’’ (unpublished data). yeo, et al.; journal of pancreatic cancer , . http://online.liebertpub.com/doi/ . /pancan. . based on these results, we have implemented a more per- sonalized enrollment procedure and highlight data secu- rity and the confidential nature of the jptr information. identification of high-risk nafms a cohort of high-risk nafms (n = ) have been iden- tified using the following criteria: first and second- degree relatives with confirmed pc, known high-risk familial syndromes (hereditary pancreatitis, hereditary nonpolyposis colorectal cancer [lynch syndrome], he- reditary breast and ovarian cancer, familial atypical multiple mole melanoma [fammm], peutz–jeghers [pj] syndrome), known brca or brca mutations, family or personal history of ovarian cancer, cigarette smoking, pack-years smoked, second-hand smoke ex- posure, and exposure to asbestos, pesticides, herbicides, or residential radon, wood dust, and other known carcinogens. canto et al. have shown some benefit in screening high-risk individuals through endoscopic ultrasound (eus) and computed tomography screen- ing. , the diagnostic yield for finding actionable pancreatic neoplasms was only . % ( / ) in a study of high-risk individuals with two or three family members with pc and one patient with pj syndrome. a prospective study of high-risk individuals and controls had a % diagnostic yield using eus at baseline and at months. thus, we encour- age high-risk nafms to seek consultation with a ge- netic counselor and a gastroenterology pancreas specialist (skilled in eus) to undergo assessment and a screening workup consistent with the interna- tional cancer of the pancreas screening (caps) con- sortium recommendations. annual tracking we have been conducting annual follow-up on the jptr cohort since . in , the response rate was a remarkable %. the most recent data from to are presented in table . the annual update was sent to persons: responses were received ( %), with persons ( %) either not responding or the letter was returned to sender. no new cases of pc were reported. concurrently, the annual survivor survey was mailed to registrants, presumed to be liv- ing. we received responses for a % return rate. of those persons responding, % had a cancer, ( % of which was pc, % periampullary, % bile duct, and % duodenal). twenty-nine percent had a benign condi- tion including ipmns, pancreas cysts, pancreatitis, and pnets. the majority of respondents had undergone surgery ( %) for either a malignant or benign neo- plasm. a subset received chemotherapy and/or rt after surgery, whereas four persons did not undergo sur- gery, but did undergo chemotherapy. ninety-six percent of the respondents were alive, with five spouses complet- ing the survey as a proxy for their deceased spouse. more women ( %) than men returned the survivor survey. quality of life as part of the survivor survey, patients were queried about their perceived quality of life and persistent symptoms (table ). on a scale of – , where repre- sents poor quality and represents excellent, quality of life was rated . / . the ability to perform activities of daily living on a scale of – was rated . / . seventy- six percent of respondents were walking regularly and % reported that they exercised regularly. the most common activities performed were in rank order: walk- ing, lifting weights, ‘‘going to the gym,’’ golfing, ellipti- cal use, biking, use of a treadmill, and going to physical therapy. eighty patients reported being involved in additional types of physical activity. persistent bothersome symptoms were reported by respondents as follows: fatigue ( %), diarrhea ( %), bloating ( %), weight loss ( %), and pain and poor appetite ( % each). these particular symptoms

most persistent and bothersome adverse ef- fect. half of the respondents still required exogenous pancreatic enzymes on a daily basis. only % reported using medical marijuana to deal with pain issues. this year, we added a question on one’s ability to return to work. fifty respondents were retired at the time of diagnosis, were able to return to their preill- ness occupation, people reported inability to perform their previous job, and people reported that they were unable to get a position in their field because of per- ceived discrimination by employers regarding their cancer diagnosis. this perception merits further inves- tigation in future surveys. satisfaction with decision-making choices survivor survey respondents (n = ) were also asked a series of questions designed to determine their satis- faction with the decisions that they had made regard- ing their treatment options (table ). to clarify, of the respondents had either pancreatic, ampullary, bile duct, or duodenal cancers and had nonmalig- nant conditions at the time they entered the jptr. ninety-seven of these respondents underwent surgery, the pppd being the most common operation. the ma- jority of these patients also opted for adjuvant chemo- therapy and/or rt. four patients in the sample had cancer but did not undergo surgery; they received only chemotherapy. the stage of disease at the time of the survivor survey was not known. surgery was clearly felt to be the most valuable treat- ment choice with % responding ‘‘yes’’ they would have surgery again, % responding that they would have chemotherapy again, and only % felt that they would have rt again. cancer survivors were also asked a hypothetical question about treatment if their cancer returned. seventy-six respondents replied that they would have surgery again, two said ‘‘no,’’ and two replied ‘‘maybe,’’ indicating that they would have to con- sider ‘‘other factors.’’ more than respondents were aware of palliative care therapies and persons reported receiving palliative care at the time of the survey. table . – jefferson pancreas tumor registry quality-of-life findings rate your quality of life . / ( – , = poor, =

report on our institu- tional experience and a paradigm for establishing a spe- cialized registry. the annual longitudinal follow-up on a cohort of pc and other survivors offers us the oppor- tunity to chart the natural history of the disease. the ability to correlate the tumor biology with family history is a window into actionable molecular targets and rec- ommendations for family member genetic testing. limitations of the study registry data are subject to inherent limitations that restrict its generalizability. quality control problems exist, such as incomplete and inaccurate data. most of the demographic information is self-reported and unverified, and measures of occupational and environ- mental exposures are not quantifiable. owing to the various methods by which one can join the jptr, we do not collect information on the stage of disease at the time of enrollment. issues that are more difficult are potential noncon- cordance between pathologists about the diagnosis of pancreas cancer, and the fact that persons can have more than one cancer and other comorbidities that in- fluence survival and quality of life. enrollment in a private disease-specific registry such as the jptr is voluntary and, therefore, does not represent the over- all u.s. epidemiology of pc, particularly with regard to race and ethnic demographics. in the case of the jptr, this is a geographic limitation and solely a func- tion of patients who chose to come to our center and not any intentional selection bias. all patients meeting the eligibility criteria are encouraged to participate. in addition, as is found across multiple institutions, biobanking and the integrity of the tissue preserved could be a limitation for specific molecular profiling studies performed in a retrospective manner, particularly with analytes susceptible to degradation, such as rna. discussion we report an above-average response rate (exceptional at % in ) to our two annual jptr follow-up sur- veys, which indicates a committed patient population and speaks to the quality and maintenance of the reg- istry database. jptr enrollees report a high degree of satisfaction with their decision-making choices despite some having conditions with a poor prognosis. this in- dicates the importance to patients of having input and a degree of control about their treatment options. more patients this year were aware of palliative care and a small number were receiving it. a high quality of life was reported by both patients with cancer and those treated for premalignant and benign disease. survivors remained physically active despite lingering adverse effects—fatigue and gastrointestinal problems being the most prevalent. overall this subset of jptr registrants is a high-functioning group. the availability and use of registry data such as the jptr enhance the ability to investigate potentially im- portant heritable gene mutations and snps that may be actionable. evaluating this type of data is impor- tant when advising patients on treatment options and when providing advice to individuals regarding screen- ing benefits and costs. in addition, the jptr offers a rare opportunity to glimpse into the lived experience of those who have pancreas, biliary, and other related cancers and condi- tions in a prospective longitudinal manner. as such, this is precious data. cancer registries have not rou- tinely tracked quality of life (such as long-term side effects of treatment and work disability) between diag- nosis and death because it requires complex data col- lection by direct patient contact. the jptr is unique in that through our annual update and survivor sur- vey, we have documented the lived experience of per- sons with pc. our future plans for the registry are to continue to evolve and query survivors about matters that are pertinent and relevant to their lives. scientifically, serial follow-up and linking individuals with pancreas and related cancers to genetic back- grounds (familial and ancestry) along with environ- mental landscapes will continue to allow us to gain insights into this disease. for example, the jptr may allow us to address the following: how can we better identify high-risk individuals? what life style changes may help curtail the development of this disease? which patients are best served by surgery and which pa- tients should receive other therapeutic interventions? conclusions this interim report of the jptr describes the utility of a specialized cancer registry for scientific discovery, monitoring disease status, determining survivorship, and identifying high-risk nafms for surveillance and screening. the jptr is an invaluable resource at our in- stitution for its ability to provide a link for families and their nonaffected relatives to monitor research progress related to their conditions. as researchers, it enables us to contact patients to determine comorbidities and survival status. as a community resource, it provides yeo, et al.; journal of pancreatic cancer , . http://online.liebertpub.com/doi/ . /pancan. . continuity between patients and their family members and the surgeons, nurses, oncologists, and scientists who are making unique discoveries about the biology of the diseases and innovative therapies. acknowledgments funding to support the ongoing activities of the jptr

tionships,” conducted in , found that % of online teens use im, and % of these individuals use it regularly. a more recent pew study, “how americans use instant mes- saging,” posited that % of internet users ages to have used im. according to the pew study more than million americans use im, with % stating they use it more frequently than e-mail. the radicati group projects the number of ims sent daily will grow from . billion in to . billion in . another pew internet and american life project, “teens and tech- nology,” found that im is one of many new technologies preferred for talking to friends and that e-mail is used to communicate with “old peo- ple,” although other studies have refuted this claim. for example, the medical reference services quarterly ecar study of undergraduate students and information technology surveyed , students in and found they overwhelmingly pre- ferred e-mail to im. the henry j. kaiser family foundation’s study, “media multitasking among american youth: prevalence, predictors and pairings,” reports the total weekly hours (based on diary data) de- voted to im is one hour and four minutes, while the three most common multitasking activities paired with im include music, web surfing, and e-mail. im is popular, but still trails e-mail in popularity of use. fifty-three percent of adult internet users sent or read e-mail on a typ- ical day in december , which is an increase of just % since . as noted by the authors of “riding the waves of ‘web . ,’” the % of adult internet users who sent or read e-mail on a typical day is more than im, blogging, and online shopping combined. instant messaging–use in medical schools e-mail is still being used on college campuses, but with so many new forms of communication, the information services (reference) depart- ment decided to investigate them for opportunities to extend services. in august , the incoming medical school class of the jefferson medi- cal college ( students) answered a short survey. one question asked if the students im; % reported using im, with % not using any im program. the number of academic and research libraries using im or real-time digital reference services in various forms continues to grow and reflect its popularity among matriculating students. in the fall of , cleveland and philbrick conducted a study to de- termine current trends in virtual reference services in academic health sciences libraries. they examined the web sites of the academic health sciences libraries represented in the membership directory of the association of academic health sciences libraries (aahsl). the majority ( , or %) offered virtual reference services with only ( %) not offering virtual reference services. however, only ( %) offered chat reference services and ( %) offered im reference ser- vices. a similar study conducted several years earlier in found similar levels ( %) of virtual reference services. future studies could examine why more libraries have decided not to offer im or chat. jefferson librarians were aware that im had become a popular mode of communication. many businesses, including database vendors, had started offering im and chat functionality to their web sites. in an effort to offer these same services to patrons, jefferson librarians decided to add im to existing e-mail, phone, and in-person reference services. im daniel g. kipnis and gary e. kaplan would not replace these services but would be offered as a supplemen- tary communication method to reach and educate patrons, , in short, an extension of existing reference services. project set-up jefferson librarians considered commercial virtual reference soft- ware. however, evidence that these platforms had technical barriers to use, such as pop-up blockers and required forms, and that some librar- ies had discontinued their services for lack of added value led to the decision to begin with a low-cost im pilot. jefferson librarians selected the trillian software because it supported multiple im networks in one interface and the basic version was free. in the winter of , information services initiated the pilot im proj- ect. the reference service supported the aim, yahoo!, and msn net- works. screen names were added to the ask a librarian web page, which provides all of the methods for contacting the reference service: im, e-mail, chat, telephone, in-person, and a knowledge base of fre- quently asked questions. to better promote the service, a link was added to the library banner in the upper right-hand corner that appears on every library web page (see figure ). during the pilot, librarians practiced im within the department, test- ing the various networks on campus, testing the video and document transfer features, and trying to standardize a cohesive narrative includ- ing greetings and responses for frequently asked questions. software costs and staffing issues thomas jefferson paid $ to upgrade to trillianpro for its google talk and meebo support. despite the minimal software costs, the library staff did invest significant staff time to plan, design, and promote the service and continued to spend time evaluating and improving it. one librarian led the project, with eight librarians and two reference tech- nicians eventually trained, staffing the service and participating in its development. reference librarians were initially assigned im shifts from their of- fices in the afternoon. after a few weeks, im requests were few, so it was decided to expand the service to full reference hours, while still mon- itoring from librarian offices. because the scheduling was cumbersome medical reference services quarterly and traffic remained low, the service was consolidated with the librar- ian at the reference desk. this led to consistent scheduling and provi- sion of reference service. transcript analysis by february , im questions had been answered. coinciding with the first-year anniversary of the service, the transcripts were ana- lyzed. of the messages analyzed, september had the highest num- ber of im questions, with a total of . may had the lowest, with only one question. the numbers correlate with the start and end of the academic year. on average, the reference desk answered . questions per month (see figure ). most popular time of day for questions the most popular time of day for receiving im questions was between : p.m. and : p.m. (see figure ). the least popular time was during daniel g. kipnis and gary e. kaplan figure . ask a librarian link to chat, e-mail, im, and phone information the morning, from : a.m. to : a.m. the service was staffed from : a.m. to p.m., monday to thursday; : a.m. to : p.m. on friday; and : a.m. to : p.m. on saturday. there is no reference service on sunday. most popular day for questions the most popular day of the week to ask an im question was thurs- day ( questions) (see figure ). the least popular day was friday (

interactions was . minutes. a total of , minutes ( . hours) was spent answering im questions. the longest interactions lasted minutes, and two interactions lasted only one minute. medical reference services quarterly figure . session frequency per month types of questions asked via im to help examine the types of questions received via im, librarians created the following categories: • technology (login, access to database, wireless, course manage- ment systems, for example, “i’m having trouble logging into ovid. is it down?”) • document delivery (ill, catalog, requesting journal, book or ci- tation, license exceeded, for example, “the catalog says you don’t have the journal i need. how can i get an article from it?”) • reference question (statistics, phone numbers, database instruc- tion, for example, “i am trying to get a recent article on the follow- ing topic: retail health clinics such as take care systems [run by nurse practitioners] and quality of care delivered by them compared to primary care physicians.”) • library policy (hours, borrowing policies, etc., for example, “hi, when does the library close today?”) • curriculum/class assistance (help with specific class assignments, for example, questions from first-year medical students about their self-directed learning cases) • bibliographic management software question (refworks and how to cite resources, for example, “i’m off campus. how can i login to refworks?”) daniel g. kipnis and gary e. kaplan figure . most popular time of day to send im questions many jefferson librarians have noticed that the majority of questions asked at the reference desk are known item requests, which have been included in “document delivery,” and this is true of the im data as well (see figure ). a close second is the category of reference questions. navigating the library’s electronic collection continues to produce many questions from patrons. surprisingly more technology questions were not asked via im. this could be attributed to the learning resources center (computer lab) answering many of the technology questions on campus. bibliographic management continues to be a popular ques- tion type, for example, how to cite specific resources using apa, how to login to refworks from off-campus, and how to format a bibliography. policy and technology questions were almost all handled in min- utes or less. among the longer transactions taking over minutes were six questions ( %) concerning bibliographic management software. based on the time spent answering these, the library created, recorded, and printed tutorials to help address these questions. did the reference librarians introduce themselves? similar to the traditional face-to-face reference interview, an initial greeting is important and can establish approachability and credibility. medical reference services quarterly figure . day of the week im questions were asked according to research, patrons are more satisfied and have more positive reactions to their library interactions when employees use their names. some suggest that patrons feel more comfortable asking their questions anonymously without feeling embarrassed or frightened. , im tech- nology is ideal for this type of interaction. in “the generic librarian,” joan durrance reported that “citizen leaders” who knew a librarian by name were far more likely to think highly of the library as an important information source for their “real world” public policy activities than those who did not. for these reasons, reference librarians who answered im questions were instructed to introduce themselves by name and title. the analysis at jefferson looked at how many times the reference li- brarians introduced themselves by first name and how many times the pa- trons volunteered to share their names with the librarians. of the total interactions, librarians introduced themselves times ( %). patrons introduced themselves times ( %). user affiliations one hundred two questions were asked by unique users, of which asked more than one question. of the questions, self-re- ported their affiliation. more than three-fourths of these ( %) were daniel g. kipnis and gary e. kaplan figure . types of questions asked via im jeffersonians (students, staff, faculty, and alumni). other users included high school students, paralegals, and students from other universities. although the location of users was not solicited, the transcripts some- times made it apparent. of those, were off-campus and five were on campus. did patrons use im lingo that confused librarians? the chronicle of higher education and other media outlets have re- ported that college students have started to incorporate im acronyms in their essays and other class assignments. , the popularity of im acro- nyms posed a concern for librarians. during staff training a list of popu- lar acronyms was shared to familiarize librarians with lingo. however, very few chat sessions included any im lingo. of the sessions that did, were simply u for you and other variations (“r u there?”). only seven sessions used acronyms and only four unique terms were used (brb; lol; ic; afk). only once was a librarian uncertain of the meaning (afk, away from keyboard). while librarians who are new to chat may need to become accustomed to less formal language, im acronyms were not a barrier to use. survey results with each im interaction, librarians sent a short online survey to users to gather feedback on the new service. below are a few comments received from im patrons: great idea, thanks! i enjoyed it very much. a very valuable service. this was great. this is a wonderful service. my mother is a medical reference librarian and i told her how great and useful this is, especially for someone living off campus without easy access to the library and staff. medical reference services quarterly overall, the positive reactions echo those from other institutions who have published similar survey results. one patron did express technological frustrations: instant messaging–another technological bane of our existence. an- other interruption. another fixation on the “instant.” i don’t think it’s the right direction for us to be moving forward in our technologi- cal–or overly technological—society. we need to foster the personal, the long-range view, and depth. “instant messaging” fails on these counts. of the surveys received ( % response rate) from january , to february , , the majority of the users were very satisfied and would use the service in the future. the breakdown of respondents who answered the online survey included: students, staff members, one faculty member, and one alumnus. when asked if patrons would use the service in the future, responded “yes” and six indicated “no.” user satisfaction was high; patrons were very satisfied, four some- what satisfied, six neutral, and six had no response. perceptions from librarians who staff the im service by the end of the first year, all librarians who worked a shift at the reference desk were participating in the chat service. a survey of these staffers was distributed to determine if they valued the service and whether it should be continued. because the service is a project of cer- tain individuals on the staff, it was important for the chat operators to have a chance to express their opinions anonymously. a short question- naire with six questions was prepared, and the administrative assistant for the library’s parent organization administered it. all nine operators completed the survey. of those, ( %) said they would like to continue staffing the service over the coming year and that the library should continue the service. of the five non-exclusive options representing the value of the jefferson im reference service, its ability to improve relationships with users was the most frequently selected ( , %). broadening the reach of the library’s reference service to underserved populations and increas- ing users’ productivity were the next most commonly chosen ( , %). daniel g. kipnis and gary e. kaplan increasing speed ( , %) and accuracy ( , %) of the reference ser- vice were the least chosen benefits. three respondents added free-form comments. two qualified the values, and one requested improvements to procedures. • while use has been low, i think it is well appreciated by those who use it. • i don’t believe it improves accuracy–speed perhaps–but not accu- racy. • [reach] no evidence that the users were otherwise underserved. rather the opposite, because they found out about it as a result of either already using our online services or reading our promotional literature. • [accuracy] no reason an im answer should be any more or less ac- curate than any other medium. • [speed] maybe. it’s no faster than a phone call, but definitely faster than in-person visit or -hour email. it may actually be slower than a phone call. • [relationships] maybe. offers a different kind of relationship which seems to be welcome to some users. • we simply need to continue to offer reference service through all plausible means of communication. • the alert requiring folks to add a patron as a buddy before the chat box opens is frequently inadvertently ignored and the opportunity to chat w/a user is thwarted. is there a solution? • current stats for im are tedious! is this not something that can be compiled all at once and scored by person? lessons learned during the pilot, lessons learned included: • the university firewall prevented the use of trillian’s file transfer and video capabilities. e-mail continued to be the preferred method of sending files. • librarians needed practice to get in the habit of greeting patrons with an appropriate introduction. • a naming standard was important for saving transcripts to a reposi- tory. the information services staff devised the following standard: year, month, day, start time, im network, question (e.g., _ _aim_catalog.txt) medical reference services quarterly • determining who and how the librarians would answer ims changed during the pilot. initially librarians were assigned a shift in their office in addition to their traditional reference desk shift, but it worked more smoothly having reference librarians monitor im, answering questions directly from the reference desk when- ever it was open. • speakers with sound were installed at the reference desk to help li- brarians hear incoming messages. • until habits were formed, one librarian was assigned to monitor that all the reference librarians on duty be online and that all tran- scripts and statistics be recorded. • it should not be assumed that all reference staff have experience and are comfortable with im. all staff were encouraged to open their own accounts and practice with colleagues before answering questions from patrons. • the following techniques were stressed to all librarians who an- swered questions: introduce yourself by name, conduct a reference interview, make sure that the patron received what was needed, and send a link to the survey. • im offers reference departments an additional means of communi- cation for users to ask questions. some questions are straightfor- ward and resolved during the im transaction (see appendix a), while others are resolved with a follow-up phone call, e-mail, or in-person consultation (see appendix b). • several canned messages were drafted, but ultimately it was easier to respond to each message rather than to search for a canned mes- sage. moreover, canned messages seemed negative and impersonal, detracting from the goal of conveying that a librarian is answering their question and not just another automated answering service. • a disadvantage is the difficulty in conducting instruction via this platform. typing out directions is time consuming and this mode of communication makes it easy to just share a url or answer, rather than teaching users to become more information literate and self-sufficient. • an online survey was sent to im users who asked questions. after a question was answered the librarians would send the url to patrons to help gather their thoughts on the program and receive feedback to improve the service. • in an effort to promote the service, im information was added to multiple pages on the library web site, posters around campus, daniel g. kipnis and gary e. kaplan flyers at library service points, and included in all library orienta- tions to new students, staff, and faculty. • in december , trillian pro ($ ) was purchased for its sup- port of the jabber network used by google talk and meebo. it was installed on one reference desk computer. • a free meebo widget was added to the ask a librarian and im pages. this made it easy for patrons visiting the pages to submit questions without needing an im account. conclusion the trend towards communicating with students in new ways now includes cell phone text messages, ims, myspace, and facebook social- networking services. chat has evolved to include the next generation of features: location based chat, flexible identities, and contextual chat. qualitative studies confirm that im will continue to expand into the fu- ture. as noted in observations by students at the university of wisconsin- milwaukee, “i’m hopeful that the use of im will expand into the future, as the use of e-mail has. communication is an essential element of in- struction.” also, “as email is a step up from snail mail, im is a step up from e-mail and telephones in the educational and business setting. instant communication is essential in the fast-paced world of technology.” at thomas jefferson university the first step into these communica- tion channels was a pilot im reference service. analysis of the first year’s session transcripts demostrated that: • im acronyms are not as commonly used in academic chat as antici- pated. extensive staff training to learn im acronyms is not needed. • the most frequent im question type asked fell under the category of document delivery. • traditional reference statistics gathering does not offer the level of detail of an im transcript. • archived transcripts helped reference staff identify usage patterns. reference staff learned that afternoon and evening hours were pop- ular times to use im. • analyzing archived transcripts helped reference staff understand patrons’ needs. this helped library staff identify areas where more help documentation was needed. these findings highlight and confirm two assumptions. first, the ma- jority of questions asked via im continue to be document delivery, medical reference services quarterly demonstrating a need to improve how electronic resources are pre- sented to patrons. second, free im services are a viable means of offer- ing reference for a small-to-medium sized medical library. with the growth of online communication methods, such as im and chat, and the incorporation of these technologies in academic health sciences librar- ies, additional studies analyzing these services and their effects on tra- ditional reference models are needed. based on user survey results and transcript analysis, the im service at tju has proved to be sufficiently effective to offer it for a second year. staff will continue to improve it by monitoring the current service and investigating new developments in virtual reference software. received: may , revised: july , , august , accepted: august , references .

access under cc by-nc-nd license. charged particle radiotherapy (cpt) has been under the spot- light for many years. investigators are looking for an answer to the question: how does it influence the outcome of cancer patients [ – ]? based on the dose distributions, it has been concluded that the use of protons may lead to improved coverage of the planning target volume (ptv) and reduced doses to many organs at risk (oar) [ – ]. several systematic reviews performed during the last decade [ , – ] investigating the clinical efficacy of cpt show that, for most indications, no firm conclusions can be drawn. in part this is due to a lack of high quality data, making adequate comparisons impossible. in addition, cost-effectiveness analysis of this technol- ogy also could not clearly demonstrate that cpt was more cost- effective than the most advanced photon technology, such as stereotactic body radiotherapy (sbrt or stereotactic ablative radio- therapy, sabr) or intensity modulated radiotherapy (imrt) [ , , – ]. the published results generated a world-wide debate between proponents and sceptics [ ]. because so many patients have been treated with protons and c-ions world-wide, we performed a new systematic review of the literature, years after our previous publication [ ]. the full report is available on line as a supplementary file. our main goal was to explore to which

sobering to observe that no phase iii trials have been per- formed and from the many retrospective and the few prospective series, we still cannot conclude that protons or c-ions are truly superior to x-rays. moreover, many of the available clinical studies were performed at a time when the current proton techniques and the newest x-ray treatment, including imaging and adaptation, were not available. our former conclusion thus still stands: except for rare indications such as childhood cancer, the gain from intro- ducing proton therapies into clinical practice remains controver- sial. the contention that protons are more suitable when oar dose constraints limit the delivery of the most appropriate tumour x-ray radiotherapy doses is compelling, but remains unproven. nor do we know if cpt allows radiation dose escalation without increasing side effects – leading to improved local tumour control and survival. where dose escalation is achievable by the most recent x-ray based techniques, the gain from proton therapy is con- fined to a reduction in dose to organs away from the target region. these arguments depend on the accuracy of the predicted dose distribution and sound estimates of the relative biological effec- tiveness (rbe) values for the cancer and for each normal tissue [ ]. the debate between the advocates in favour of randomised studies for all circumstances, and those who consider this to be unethical when reduced radiation dose can be delivered to oar, continues [ – ]. x-ray (photon) treatment and imaging techniques have significantly improved over recent decades with increased implementation of imrt, arc and helical treatment and sabr in routine clinical practice [ – ]. together with imaging developments such as ct-, mri- and pet-based

algorithms, x-ray therapy allows the delivery of radiotherapy to high doses. modern x-ray techniques in common malignancies such as non-small cell lung cancer are comparable to, or even supe- rior to, that of protons therapy delivered with passive scattering techniques [ ]. however x-ray techniques will always deliver a higher integral dose than protons and there is concern about low dose effects to a wider volume because of enhanced cancer induc- tion and circulatory system risks [ – ]. at the same time proton therapy has also significantly improved, allowing the delivery of intensity modulated proton therapy (impt) with commercial sys- tems [ ]. at present, many planning studies show that for the high dose regions, the best available x-ray and proton treatments result in similar dose distributions within and around the tumour. however the medium and low dose volumes are smaller and receive less radiation dose with impt than with any x-ray technique [ – ]. proponents of protons view the data as a proof that ultimately pro- ton therapy will supersede x-rays because it is generally agreed that the alara (as low as reasonably achievable) principle should be followed [ ]. arguments against this viewpoint are that a reduction of the medium and low dose volumes are not beneficial for the patient when only a shallow dose–response relationship be- tween an intermediate dose and side-effects exists or when the side effects are of no clinical relevance or occur in only a small pro- portion of patients. balanced arguments, considering many of the technical aspects have been published recently (e.g. [ , ]). when some oars can be spared more effectively with protons than x-rays, even for the medium or low dose levels, more effective dose-escalation may be possible, either for radiotherapy or for combined radiation and systemic treatment. because the absorption and range of protons is more dependent on electron density inhomogeneity than x-rays, small shifts of the tumour or of the oars in areas with high density gradients, e.g. in the lungs (where not only lung density but also tumour position varies with breathing), may directly result in large changes and er- rors in dose distribution. adaptive radiotherapy techniques thus become even more important for protons than for x-rays, and these are in development for each modality [ , ]. probability based treatment planning strategies taking into account volume changes and shifts of the tumour and the oars have been described allow- ing more robust dose distributions for scanned proton beams, although there is a longer history of using respiratory gating tech- niques in proton therapy than in the case of x-ray therapy [ ]. if proton therapy can fulfil its initial promise it may well turn out to be a cost-effective intervention [ ]. it is necessary to break the current vicious circle where the lack of robust clinical data leads to a lack of evidence to support funding and further develop- ment of proton beam therapy in state-of-the-art treatment centres with responsibilities to produce robust clinical data [ , ]. the root cause of the problem facing proton therapy is the historic fail- ure to leverage the collection and sharing of anonymised data in return for capital investment in what is, to all intents and purposes, still a developing and experimental technology. unless the present culture is radically changed this collaborative failure will continue to be proton therapy’s achilles heel. we believe that randomised phase iii trials will be needed for some, but not necessarily all, situations to investigate the role of protons and their cost-effectiveness. prospective phase ii studies using the best available techniques and reporting agreed endpoints of clinical relevance are the minimum requirement. as recom- mended previously, all studies should be fully integrated in large international networks and databases to make reliable and rapid progress: this needs urgent implementation. new particle beam centres should be funded with a provision for shared basic research, technical improvements and properly conducted trials. an enhanced level of global, or at least continen- tal or national, governance of particle therapy is of paramount importance. only then, will we be in a position to clarify the real gain of cpt and to bring an otherwise endless debate to an unequivocal conclusion. research support and disclaimer this article is based on the results of our update of ref.

and chemokine receptor-binding sites. additionally, by incorporating t - and -helix- resistance mutations into individual env protomers, we were able to interrogate exposure of discrete gp n-hr and c-hr domains. our data indicate that a single cd binding to an env trimer is sufficient to promote fusion. moreover, the first cd binding event appeared to expose only one of three possible binding sites for each fusion inhibitor, suggesting an asymmetric transition into the phi. this asymmetry was significantly more pronounced in the gp n-hr region compared to the gp c-hr region. these results can be used to explain the multiphasic titration of mutant env homotrimers that naturally form asymmetric n-hr domain structures. taken together, these data suggest that the native state-to-phi transition of env occurs in a multistep (asymmetric) fashion. -pos board b evolution of hiv- resistance to a cholesterol-linked d-peptide fusion inhibitor amanda e. siglin , nicholas francis , michael s. kay , micheal j. root . thomas jefferson university, philadelphia, pa, usa, university of utah, salt lake city, ut, usa. during hiv- entry, the n-hr and c-hr regions of the gp viral glycoprotein associate to form a trimer-of-hairpins critical for membrane fusion. the n-hr region contains a highly conserved hydrophobic pocket that is the target for a multivalent, d-peptide fusion inhibitor, pie -trimer. recently, a modified form of this inhibitor with a conjugated cholesterol (chol-pie -trimer) was shown to possess up to -fold increased potency, presumably due to mem- brane targeting. here, we determined the resistance profile of chol-pie - trimer starting from either inhibitor-naı̈ve or pie -trimer-resistant hiv- (nl - strain). viral propagation in increasing inhibitor concentrations pro- duced hiv- populations with - to -fold reduced sensitivity chol- pie -trimer. these viruses were also resistant to the parental, unconjugated inhibitor pie -trimer. using hiv- fusion inhibitors di-c and -helix, we were able to interrogate the effect of escape mutations on the exposure of the gp n-hr and c-hr regions, respectively. resistance to chol-pie - trimer resulted in a slight decrease in the temporal window of n-hr exposure, regardless of the starting viral population. exposure of the c-hr region was unchanged for resistant viruses generated from the inhibitor-naı̈ve viral pool. by contrast, the temporal window of c-hr exposure was significantly increased (> -fold) for resistant viruses that were generated from the pie -trimer-resistant viral pool. efforts to identify the mechanisms of chol- pie -trimer resistance and the decoupling of n-hr and c-hr exposure are underway. -pos board b fusogenic activity of the hiv- gp mper-tmd region: mechanism and targeting by immunogens and inhibitors jose l. nieva , beatriz apellaniz , carmen domene , nerea huarte , eneko largo . biophysics unit (csic-upv/ehu) and dept. of biochemistry, university of the basque country (upv/ehu), bilbao, spain, chemistry research laboratory, university of oxford, oxford, united kingdom. fusion of the viral envelope with the cell membrane marks the beginning of the hiv- replicative cycle. this event is targeted by inhibitors currently in clinical use and by preventive vaccines under development. antibodies e and e bind to the gp membrane proximal external region (mper)- transmembrane domain (tmd) junction and block fusion. these antibodies display the broadest viral neutralization known to date, which underscores the conservation and functionality of the mper-tmd region. in recent work, we have described that peptides representing this region have potent membrane-destabilizing effects. here, based on the outcome of vesicle assays, atomic force microscopy studies and molecular dynamics simulations, we propose a mechanism for the involvement of the mper-tmd region in hiv- fusion. in addition, we provide evidence that underpins the poten- tial use of its activity as a new target for inhibitor and immunogen development. -pos board b studies on the membrane-active behavior of outer membrane vesicles from a gram negative bacterium william bartos, rensa chen, donald y. kobayashi, paul r. meers. rutgers, the state university of new jersey, new brunswick, nj, usa. gram-negative bacteria are known to produce small ~ - nm vesicles by ‘‘blebbing’’ of their outer membranes. these outer membrane vesicles (omv) have been implicated in activities such as transmission of virulence fac- tors, horizontal gene transfer and development of biofilms. in this investigation, the interactions of omv from lysobacter enzymogenes (strain c ) with other membranes have been monitored using fluorescent assays for association and/or fusion. defined composition large unilamellar vesicles labeled with the fluorescence resonance energy transfer (fret) pair , -dipalmitoyl-sn- glycero- -phosphoethanolamine-n-( -nitro- - , -benzoxadiazol- -yl) (nbd- pe) and , -dipalmitoyl-sn-glycero- -phosphoethanolamine-n-(lissamine rho- damine b sulfonyl) (rh-pe) were incubated with isolated omv to observe the interaction via the fret ratio of donor/acceptor. omv substantially increased this ratio over the course of about an hour (t / ~ - min.) at �c, when added directly to vesicles comprising disordered or fluid lipids, such as -palmitoyl- -oleoyl-sn-glycero- -phospho-( ’-rac-glycerol) (popg), -pal- mitoyl- -oleoyl-sn-glycero- -phosphoethanolamine (pope) or -palmitoyl- - oleoyl-sn-glycero- -phosphocholine (popc). this apparent fusion was much more limited or absent with liquid ordered membranes of , -dipalmitoyl-sn- glycero- -phosphocholine/cholesterol (dppc/chol). in the case of popg/ pope / vesicles, apparent fusion was also confirmed by testing vesicles with exclusively inner monolayer fluorescent probes to diminish any fluores- cence changes from external interactions of outer monolayer fluorophores. when the omv were labeled with the fluorophore , -dioctadecyl- , , , - tetramethylindocarbocyanine, and incubated with a natural host, yeast cells (strain s ), association and/or fusion was observed by co-sedimentation of the omv label with yeast cells. these studies may help to elucidate the mech- anism of natural host-pathogen interactions and define the lipid specificity for hiv fusion peptide perturbs membrane structure in a cholesterol dependent fashion cd binding induces an asymmetric transition of hiv- env from its native conformation into the prehairpin intermediate state evolution of hiv- resistance to a cholesterol-linked d-peptide fusion inhibitor fusogenic activity of the hiv- gp mper-tmd region: mechanism and targeting by immunogens and inhibitors studies on the membrane-active behavior of outer membrane vesicles from a gram negative bacterium judicial foreign policy: lessons from the s judicial foreign policy: lessons from the s david sloss i. introduction in his dissenting opinion in hamdi v. rumsfeld, justice thomas cited justice jackson approvingly for the following proposition: “[t]he very nature of executive decisions as to foreign policy is political, not judicial. such decisions are wholly confided by our constitution to the political departments of the government . . . they are decisions of a kind . . . which has long been held to belong in the domain of political power not subject to judicial intrusion or inquiry.” under this view, which i will call the “exclusive political control” thesis, the judiciary is barred from participating in foreign affairs decision-making because the constitution grants the political branches exclusive control over foreign policy. several scholars have defended variants of the exclusive political control thesis. this article demonstrates that the exclusive political control thesis is incompatible with the original understanding of the founders. the article does not defend originalism as a method of constitutional interpretation; it merely shows that the exclusive political control thesis is inconsistent with an originalist approach. the article examines the implementation of u.s. neutrality policy in the period from to . other scholars have analyzed the initial formulation of u.s. neutrality policy in . scholars who focus narrowly on the year , when the u.s. first articulated its neutrality policy, have concluded that “the federal courts played a relatively minor role in resolving the nation’s foreign affairs problems.” however, if one expands the time frame of the analysis to include the years to , when the hamdi v. rumsfeld, us , ( ) (thomas, j., dissenting). id. at -

( dall.) ( ); del col v. arnold, u.s. ( dall.) ( ); hills v. ross, u.s. ( dall.) ( ); moodie v. ship phoebe anne, u.s. ( dall.) ( ); moodie v. ship alfred, u.s. ( dall.)

( ); and glass v. sloop betsey, u.s. ( dall.) ( ). technically, u.s. v. peters and macdonough v. dannery are not “privateer” cases because they involved french naval vessels, not privateers. even so, they are included for the sake of completeness. the ten unpublished decisions are: wallace v. brig caesar, supreme court case no. ; moodie v. the ship mermaid, supreme court case no. ; moodie v. the brig eliza, supreme court case no. ; moodie v. the ship phyn, supreme court case no. ; moodie v. the brig tivoly, supreme court case no. ; moodie v. the brig favorite, supreme court case no. ; moodie v. the ship britannia, supreme court case no. ; moodie v. the snow potowmack, supreme court case no. ; moodie v. the brig eliza, supreme court case no. ; and don diego pintado v. ship san joseph, supreme court case no. . during this period, one other french privateering case was also entered onto the supreme court docket: morphy v. ship sacra familia. however, there was no supreme court decision because the french and spanish consuls agreed to discontinue the case. see vii documentary history of the supreme court of the united states, - (marcus, ed. ), pg. [hereinafter, dhsc]. during the s, the supreme court convened for two terms each year, in february and august. over the course of seven terms from february to february , the court decided approximately cases; this figure depends upon what, precisely, is counted. for present purposes, the main point is that the french privateering cases occupied a very substantial portion of the supreme court docket during this period. for detailed information about the supreme court docket, see i dhsc, supra note , at - , - (reproducing the supreme court minutes and docket for the period - ). traditional accounts of the neutrality crisis have emphasized the supreme court’s refusal to issue an advisory opinion to the executive branch. see thomas, supra note , at - ; casto, supra note , at judicial foreign policy: lessons from the s four features of the french privateering cases, viewed together, demonstrate conclusively that the exclusive political control thesis is contrary to the original understanding of the founders. first, the french privateering cases were directly related to the implementation of u.s. neutrality policy, which was the most important national security issue of the era. second, these cases accounted for a very substantial percentage of the supreme court docket in the initial decade after adoption of the constitution. third, executive and judicial officers reached a consensus that the cases should be resolved judicially, not diplomatically. fourth, the cabinet officers and supreme court justices who formed that consensus included many of the leading figures involved in drafting and ratifying the constitution. given their agreement that the federal judiciary should play a leading role in implementing u.s. neutrality policy, claims by contemporary jurists and scholars that the founders granted the political branches exclusive responsibility for foreign policy decision-making are simply untenable. it bears emphasis that all the french privateering cases involved disputes about the property rights of private parties, and that international law provided many of the key substantive rules for resolving those disputes. thus, the government’s choice to handle these cases through litigation in federal courts illustrates two points. first, the founders were very comfortable with the idea that federal courts would invoke international law to provide rules of decision in litigation. second, the founders recognized that - . in the summer of , the executive branch submitted a set of questions to the supreme court related to french privateering. see vi dhsc, supra note , at - . the court refused to provide an answer, stating that “[t]he lines of separation drawn by the constitution between the three departments of government . . . afford strong arguments against the propriety of our extrajudicially deciding the questions alluded to.” id. at . notwithstanding this incident, though, the supreme court and the lower federal courts decided dozens of french privateering cases in the period from to , and the executive branch consistently refused to intervene in judicial decision-making. see infra part iv. three men served as secretary of state during this period: thomas jefferson ( to dec. ), edmund randolph (jan. to aug. ) and timothy pickering (aug. to may ). jefferson’s credentials as one of the key constitutional founders are well known. randolph played a key role at both the constitutional convention and the virginia state ratifying convention. see julius goebel, jr., antecedents and beginnings to (vol. i of the history of the supreme court of the united states) ( ) pgs. - , - , - . pickering was not a representative to the constitutional convention, but he did participate in the pennsylvania ratifying convention. two men served as attorney general during this period: edmund randolph ( to jan. ) and william bradford (jan. to dec. ). before becoming attorney general, bradford was a justice on the pennsylvania supreme court ( - ) and attorney general of pennsylvania ( - ). alexander hamilton served as secretary of the treasury from to feb. . although he had no formal responsibility for u.s. foreign policy, he was a key presidential advisor on a wide range of issues. hamilton’s credentials as one of the key constitutional founders are well known. three men served as chief justice during this period: john jay ( to june ), john rutledge (aug. to dec. ), and oliver ellsworth (march to dec. ). john jay, as is well known, was one of three co-authors of the federalist papers. he played a central role during the new york ratifying convention. see goebel, supra, at - . rutledge and ellsworth both served on the committee of detail during the constitutional convention. see id. at - . they also played central roles in their state ratifying conventions. see id., at - (ellsworth and connecticut); - (rutledge and south carolina). in contrast to some modern litigation, the courts were not utilizing international law as a guide to constitutional interpretation. they were applying international law directly as a rule of decision. saint louis university law journal international law, or the “law of nations” as it was known at that time, did not merely regulate relations between nations: it also conferred rights on private parties. leading originalist accounts of the constitutional separation of powers in foreign affairs have tended to overlook, or give little weight, to the french privateering cases. this is understandable because the cases themselves say very little about the constitutional distribution of power in foreign affairs. ten of the cases did not yield published decisions; in most of those cases, the court did not produce any written rationale. in many of the published decisions, the court’s written rationale says nothing about the separation of powers issues that are the central focus of this article. to shed light on these issues, the author analyzed a wide variety of ancillary materials related to the french privateering cases, including the supreme court papers in the national archives, other sources that present arguments advanced by the parties in the privateering cases, the decisions of lower courts, executive branch documents and diplomatic correspondence with france and england. the analysis of these ancillary materials suggests that the founders did not envision the lines separating the three branches of the federal government as impenetrable, immovable walls. to the contrary, the key government decision-makers in the s believed that they were engaged in a cooperative effort in which all three branches of the federal government worked together to promote u.s. foreign policy objectives. responsibility for foreign policy decision-making was not divided into neat, see generally mark w. janis, the american tradition of international law, great expectations: - ( ). see, e.g., michael d. ramsey, the constitution’s text in foreign affairs ( ) (providing a very comprehensive account of the constitutional law of foreign affairs, as it was understood by the founding generation, but devoting very little attention to the french privateering cases). the author spent two days in the national archives conducting research for this paper. he reviewed the supreme court case files for of the cases referenced above, including two published cases, and eight unpublished cases. the two published cases are: moodie v. ship phoebe anne, u.s. ( ); and moodie v. ship alfred, u.s.

( dall.) ( ). the discussion of privateering in this paragraph is drawn primarily from william r. casto, foreign affairs crises and the constitution’s case or controversy limitation: notes from the founding era, am. j. legal hist. , - ( ). with respect to letters of marque, see ingrid brunk wuerth, international law and constitutional interpretation: the commander in chief clause reconsidered, mich. l. rev. , ( ). saint louis university law journal thus, the privateering system utilized the profit motive as a force multiplier to enhance the naval power of a nation at war. as of march , france was at war not only with england, but also with austria, prussia, spain, and the netherlands. france’s naval power was no match for the combined naval forces of its enemies. accordingly, france decided to make extensive use of privateers to supplement its naval forces. the chief mission of the privateers, from france’s perspective, was to disrupt the trade of its enemies. to perform this mission effectively, the privateers had to operate near the ports that were used to conduct the enemies’ trade. hence, france deployed some privateers in the european theater and others in the western hemisphere. deployment of privateers in the western hemisphere posed tactical problems for france. it made no sense for privateers operating in the western hemisphere to carry their prizes back to france to be condemned by prize courts in france. the trans-atlantic journey was time consuming and hazardous: too many prizes would be lost en route. france established some prize courts in french colonies in the caribbean, but the british effectively blockaded key french ports in the caribbean for at least some of the period under study, making it difficult for privateers to take their prizes to caribbean ports. accordingly, france instructed many of its privateers in the western hemisphere to take their prizes to u.s. ports. france’s attempt to utilize u.s. ports as a base of operations for french privateers posed a significant policy dilemma for the united states. on the one hand, the united states was eager to honor its treaty commitments to france. on the other hand, president washington declared in april that the united states would remain neutral in the war between france and its various enemies. the dilemma arose because the treaty with france seemingly obligated the u.s. to adopt a pro-french tilt in the war. specifically, article granted french privateers broad rights of access to u.s. ports, whereas article imposed severe restrictions on access to u.s. ports by “foreign privateers . . . who have commissions from any other prince or state in enmity with” france. see proclamation of neutrality, april , , i aspfr, at (noting that “a state of war exists between austria, prussia, sardinia, great britain, and the united netherlands, of the one part, and france on the other . . .”). see also edict of his majesty, king of spain, march , , i aspfr at - (noting that france declared war against spain on march ). see, e.g., united states v. peters, u.s.

( ) (french naval vessel captured merchant ship and took it to french port in caribbean, where it was condemned as prize by a french prize court). see melvin h. jackson, privateers in charleston, - , at - ( ). see id. at - . see proclamation of neutrality, april , , i aspfr, at . see treaty of amity and commerce, u.s.-fr., art. , feb. , , reprinted in treaties and other international acts of the united states of america , - (hunter miller ed., gov’t printing office ) [hereinafter treaty with france]. see id., art , pg. - . judicial foreign policy: lessons from the s as thomas jefferson stated, “it is an essential character of neutrality, to furnish no aids (not stipulated by treaty) to one party, which we are not equally ready to furnish to the other.” thus, to implement its neutrality policy and honor its treaty commitments to france, the united states had to decide what the treaties with france required. if the u.s. adopted an expansive view of its treaty obligations to france, the british (and others) would object that the u.s. was violating its duties as a neutral state; this course potentially risked war with great britain. if the u.s. adopted a narrow view of the scope of its treaty obligations, france would object that the u.s. was breaching its treaty commitments; this course potentially risked war with france. hence, the united states attempted to steer a middle course between the scylla of war with england and the charybdis of war with france. federal courts played a critical role in attempting to chart this middle course, in part because key officers in the executive and judicial branches agreed that the judiciary should assume primary responsibility for making some of the crucial decisions. iii. u.s. neutrality policy: from february to june part three analyzes developments from february , when france declared war against great britain and holland, until june , when congress enacted legislation to address french privateering activities. there were two main sets of foreign policy issues related to the conduct of french privateers during this period. the first set of foreign policy issues related to the substantive rules governing the conduct of french privateers. the political branches generally took the lead in framing substantive rules, and the judicial branch played a secondary role. the second set of foreign policy issues related to jurisdictional questions: when french privateers captured privately owned vessels, and the owners sought restitution of the captured property on the grounds that their property had been seized illegally, the question arose as to which branch of government should resolve these disputes. initially, there was some uncertainty as to whether the executive or the judicial branch should handle these questions. france urged resolution of these disputes through diplomatic means because france viewed the privateering cases as contests between nations about sovereign rights. however, a consensus soon emerged among u.s. government officials that the judicial branch should decide these issues, because the privateering cases also involved private disputes about individual property rights. ultimately, cabinet officials and supreme court justices agreed that the judiciary had the primary constitutional responsibility for deciding individual disputes over ownership of property, even though the law of nations provided most of the governing legal rules and the disputes were intimately linked to the wartime strategy of sovereign powers. part three is divided into three sections. the first section addresses the historical context. the second section analyzes the substantive rules governing the conduct of french privateers. the third section analyzes the interplay between the legislative, letter from thomas jefferson, secretary of state, to mr. pinckney, minister plenipotentiary from the united states with great britain, sept. , , i aspfr, at . saint louis university law journal executive and judicial branches in framing the jurisdictional rules that ultimately gave the judiciary primary responsibility for resolving disputes arising from french privateering activities. a. historical context in january , french revolutionaries executed louis xvi. shortly thereafter, on february , in the midst of revolutionary fervor at home, france declared war on great britain and holland. at that point, france was already at war with austria and prussia. in march , france also declared war on spain. although france declared war against britain on february , news of the war did not reach the united states until late march or early april. president washington was in mount vernon at the time, but he traveled to philadelphia as quickly as possible to convene a meeting of his cabinet. the cabinet officers at the time included thomas jefferson as secretary of state, alexander hamilton as secretary of the treasury, henry knox as secretary of war, and edmund randolph as attorney general. the president circulated a list of questions to the cabinet officers on april , and the group convened the next day to formulate u.s. policy. on april , the president publicly issued a formal proclamation of neutrality, declaring the u.s. policy to “pursue a conduct friendly and impartial toward the belligerent powers.” on april , , edmond genet arrived in charleston, south carolina to assume his position as the new french ambassador to the united states. beginning immediately after his arrival, genet undertook a series of actions that posed substantial challenges for u.s. foreign policy. first, genet began commissioning u.s. citizens to act as privateers in the service of the french government. second, genet provided financial assistance to u.s. and french citizens who accepted commissions to serve as privateers for france. with genet’s financial aid, the privateers purchased ships and utilized u.s. ports to arm their ships for naval warfare. additionally, genet instructed french consuls in major u.s. ports to establish prize courts. consequently, french privateers commissioned by genet and outfitted in the united states began bringing their prizes into u.s. ports so that french consuls operating prize courts on u.s. territory could adjudicate the lawfulness of their prizes. in part due to the policies he pursued, and in part due to his confrontational style, genet quickly made many enemies in the u.s. government. hence, in august , the thomas, supra note , at . see edict of his majesty, king of spain, march , , i

judicial foreign policy: lessons from the s u.s. decided to request the recall of ambassador genet. the french government granted that request in october , and genet’s replacement, joseph fauchet, arrived in the u.s. in february . in the next months after president washington issued his neutrality proclamation, there were three key milestones in the development of the u.s. response to french privateering activities. first, on august , , the treasury secretary (alexander hamilton) promulgated regulations for the guidance of u.s. customs collectors. second, on february , , the supreme court issued its decision in glass v. sloop betsey. third, on june , , congress enacted legislation that was designed to regulate the activities of french privateers in u.s. ports. the treasury regulations and the subsequent legislation defined the key substantive rules governing the conduct of french privateers. in contrast, the supreme court decision in sloop betsey addressed important jurisdictional questions, and resolved key constitutional separation of powers issues that had been percolating in the executive branch and in the lower federal courts for the previous year. b. substantive rules governing privateers this section discusses the main substantive issues related to french privateering: ) whether french privateers could sell their prizes in u.s. ports; ) whether france could recruit u.s. citizens to serve as privateers on behalf of france; and ) whether french privateers could utilize u.s. ports to outfit civilian vessels for naval warfare, or to augment the military capabilities of vessels that were already equipped for naval warfare. . sale of prizes: in traditional european wars, a privateer who captured a prize would bring it to a prize court in his home country to obtain a judgment confirming that it was a lawful prize. then, when he sold the prize and its cargo, he could invoke the judgment of the prize court to prove that he had a legally valid title to the property he was selling. france attempted to export this model to the western hemisphere by establishing french prize courts on u.s. territory. the key strategic goal was to provide financial incentives for prospective privateers to operate in the american theater by establishing a juridical system that would ensure their ability to sell captured property for financial gain. without the economic inducement of a solid return on investment, france would be unable to enlist sufficient numbers of privateers, and its military strategy would fail. accordingly, genet instructed french consuls in the united states to establish prize courts on u.s. territory. genet believed that france had a right to do so under see the papers of thomas jefferson, supra note , at - . see ammon, supra note , at - . instructions to the collectors of the customs, aug. , , reprinted in i aspfr, at - . u.s.

(bypassing genet), warning them that they would be subject to prosecution and punishment if they “within the united states . . . assume to try the validity of prizes, and to give sentence thereon, as judges of admiralty.” importantly, although the executive branch determined that any judgment issued by a french prize court operating on u.s. territory was “a mere nullity,” the government did not attempt to block the sale of prizes in u.s. ports by french privateers. the decision not to interfere with the sale of captured prizes and their cargo was significant because it preserved a financial incentive for french privateers to bring their captured prizes to u.s. ports. if a privateer sold his prize without first obtaining a valid judgment from a prize court, the ship itself would sell at a discounted price because the buyer had to assume the risk that the original owner might file a legal action to claim title to the vessel. however, privateers could sell captured cargo at full value because the buyers did not face a significant risk of subsequent legal action by the original owners. overall, the financial incentives were sufficient to induce french privateers to bring captured prizes to u.s. ports and sell them for financial gain. convention defining and establishing the functions and privileges of consuls and vice consuls, nov. , , art. , u.s.-france, reprinted in treaties and other international acts of the united states of america , (hunter miller ed., ). article authorized french consuls, for example, to adjudicate disputes between a french captain and his crew while they were docked at u.s. ports. see id. it was quite a stretch, though, for genet to suggest that article authorized france to establish prize courts on u.s. territory. see, e.g., letter from thomas jefferson to george hammond, may , , papers of thomas jefferson, supra note , at -

(explaining and defending u.s. position on sale of prizes in u.s. ports). assume, for example, that a french privateer captured a british merchant vessel and sold the british vessel to an american merchant who wanted to use the vessel to conduct trans-atlantic trade. if the french privateer obtained a valid judgment from a prize court before selling the captured ship to the american buyer, then the buyer would obtain a secure title protected by that judgment. but if the american buyer purchased a ship that had not been condemned by a prize court as a valid prize, and the buyer then sailed the ship to a french port, the original british owner could initiate a legal action in a french prize court to challenge the legality of the initial capture. if the british owner prevailed, the american buyer would lose possession of the vessel and would have little recourse against the french privateer who sold him the vessel. see jackson, supra note , at - (providing detailed information about the sale of british, spanish and dutch prizes captured by french privateers and brought to the ports of charleston, sc and savannah, ga between april and april ). judicial foreign policy: lessons from the s in sum, the washington administration “split the baby” by prohibiting the establishment of french prize courts on u.s. territory, but permitting the sale of french prizes. this solomonic solution was generally consistent with france’s strategic interests. as long as french privateers could sell captured prizes and cargo in u.s. ports, there would be strong economic inducements for privateering, and france would be able to recruit a sufficient number of privateers to achieve its military objectives. . recruiting us citizens: as noted above, the success of france’s naval warfare strategy hinged on its ability to recruit a sufficient number of individuals to serve as privateers on behalf of france. article of the treaty with france prohibited u.s. citizens from taking “any commission or letters of marque for arming any ship or ships to act as privateers against” france. from france’s perspective, though, it was entirely permissible for u.s. citizens to accept commissions from france to act as privateers against france’s enemies. hence, immediately after genet arrived in the united states he began recruiting u.s. citizens to aid france’s war effort by serving as captains and/or crew on french privateers. the u.s. told france that it viewed genet’s recruitment of u.s. citizens as a contravention of u.s. neutrality policy and urged france to halt these activities. the august treasury regulations instructed u.s. customs collectors “to observe, and to notify . . . the case of any citizen of the united states who shall be found in the service of either of the parties at war.” in accordance with the president’s neutrality proclamation, federal prosecutors brought criminal charges against u.s. citizens who enlisted to serve on french privateers. some critics expressed doubts about the president’s constitutional authority to impose criminal penalties for violations of rules promulgated by the executive branch. in june , congress removed lingering doubts about the constitutionality of federal criminal prosecutions by enacting legislation that authorized criminal punishment. the legislation expressly authorized criminal penalties for u.s. citizens who “accept[ed] and exercise[d] a commission to serve a foreign prince or state in war,” and for those who treaty with france, supra note , art. , pg. . see casto, supra note , at -

( dall.) , ( ). by holding that french consuls lacked jurisdiction to operate prize courts on u.s. territory, the supreme court effectively denied res judicata effect to the prior judgments of french prize courts, thereby creating an opportunity for the owners of captured vessels to challenge the validity of (french) judgments condemning the vessels as prizes. see william r. casto, the supreme court in the early republic, at ( ). u.s. ( dall.) ( ). saint louis university law journal executive officers trusted the courts to resolve disputed cases in accordance with settled rules of international law, and assumed that the judicial application of international legal rules would help promote the u.s. goal of avoiding war with britain and france. this section examines the evolution of jurisdictional rules related to the french privateering cases in the period from april to june . the first sub-section discusses the role of the executive branch. the next sub-section examines decisions by lower federal courts before the supreme court decision in sloop betsey. the third sub- section reviews the supreme court decision in sloop betsey. the final sub-section briefly considers the role of congress. . the role of the executive branch: in late april, , the french naval vessel l’embuscade captured a british vessel, the grange, within the bay of delaware. under accepted principles of the law of nations, there was no question “that to attack an enemy in a neutral territory is absolutely unlawful.” hence, the capture of the grange raised two questions. as a factual matter, where did the capture occur? and as a legal matter, what were the boundaries of u.s. territorial waters? after investigating and analyzing these issues, attorney general randolph concluded that the capture occurred in u.s. territorial waters (i.e., neutral territory), and that “the duty arising from the illegal act, is restitution.” in deference to that judgment, genet agreed that the grange would be returned to its british owners. the grange was one of the few cases, though, where the executive branch performed the adjudicative function of deciding that the capture of a specific vessel was unlawful. after the u.s. resolved the case of the grange, it soon became apparent that there would be many such cases to resolve, and the executive grew uncomfortable with repeated demands from the french and british ambassadors, asking the executive to perform what it believed was an adjudicative function. within a period of a few days in june , secretary of state jefferson received formal protests from the british concerning the catharine and from the french concerning the william. these protests forced the cabinet to reconsider the respective roles of the executive and judicial branches in handling these disputes. first, on june , , george hammond, britain’s ambassador to the united states,” wrote to thomas jefferson to protest the seizure by french captors of the british brigantine catharine within the territorial waters of the united states. hammond requested “immediate restitution of this vessel” on the grounds that the seizure was “an aggression on the territory and jurisdiction of the united states.” the cabinet met the next day to formulate a u.s. response. they reached a unanimous agreement that the see opinion of edmund randolph (attorney general), may , , reprinted in papers of thomas jefferson, supra note , at - . id. at . id. at . see letter from citizen genet, minister plenipotentiary of the republic of france, to mr. jefferson, secretary of state of the united states, may , , i aspfr, at - . papers of thomas jefferson, supra note , at - . id. judicial foreign policy: lessons from the s matter should be resolved by judicial means. jefferson wrote to hammond to convey the u.s. views. jefferson asked hammond “to have the parties interested apprised without delay that they are to take measures as in ordinary civil cases for the support of their rights judicially.” the letter continued: should the decision be in favor of the jurisdiction of the court, it will follow that all future similar cases will devolve at once on the individuals interested to be taken care of by themselves, as in other questions of private property provided for by the laws. . . . this train of things is much more desireable for the executive, whose functions are not analogous to the questions of law and fact produced by these cases. two points are noteworthy. first, the executive branch preferred for the courts to resolve these cases because the cases involved private property rights and the application of law to fact. second, it was the judiciary’s responsibility to decide whether these were matters within the jurisdiction of federal admiralty courts. jefferson sent this letter to hammond on june . then, on june , ambassador genet wrote to jefferson to protest the seizure of the william by u.s. judicial officers: “you will see by the papers annexed hereto, that, in contempt of the treaties which unite the french and americans; that in contempt of the law of nations; civil and judiciary officers of the united states have permitted themselves” to seize prizes captured by french privateers. genet added: “i hope to obtain immediately . . . restitution, with damages and interest, of the french prizes arrested and seized at philadelphia, by an incompetent judge . . . .” genet also made clear that france believed these types of disputes should be resolved through diplomatic means, not through private adjudication. he wrote: “it is through the intervention of the public ministers, that affairs of the nature cabinet opinions on the republican and the catharine, june , , reprinted in papers of thomas jefferson, supra note , at - . letter from thomas jefferson to george hammond, june , , papers of thomas jefferson, supra note , at - . id. see letter from thomas jefferson to gouverneur morris, aug. , , papers of thomas jefferson, supra note , at , . letter from citizen genet, minister of the republic of france, to mr. jefferson, secretary of state, june , , i aspfr, at . id. the events preceding genet’s letter to jefferson merit brief comment. in the spring of , the french privateer citizen genet captured a british ship, the william, and brought it to philadelphia. the british owners filed an in rem action in federal court, alleging that the capture was illegal because the ship was seized in u.s. territorial waters. findlay v. the william, f.cas. (d. penn. ). meanwhile, on june , , an agent for the french captors proceeded to sell the cargo at a wharf in philadelphia. statement of francis dupont, french consul in philadelphia, june , , reprinted in i aspfr, at . in an effort to establish the court’s jurisdiction over the ship and its cargo, “a deputy marshal of the court of admiralty” attempted to halt the sale of the cargo. id. the agent for the french captors believed “that the admiralty could not . . . meddle in this business, agreeably to the th article of the treaty of commerce between france and the united states.” id. the agent proceeded to sell the cargo, but it allegedly sold below market value because the deputy marshal “discouraged the bidders, and even suspended their bidding.” id. saint louis university law journal which produce my present complaints and reclamations, ought to be treated.” this was consistent with france’s litigating position in these cases, which emphasized that disputes related to french privateers were, first and foremost, disputes involving sovereign rights. jefferson drafted a letter in response to genet’s protest, which included the following passage: the functions of the executive are not competent to the decision of questions of property between individuals. these are ascribed to the judiciary alone . . . you will therefore be sensible, sir, that though the president is not the organ for doing what is just in the present case, it will be effectually done by those to whom the constitution has ascribed that duty; and be assured that the interests, the rights and the dignity of the french nation will receive within the bosom of the united states all the support which a friendly nation could desire, and a neutral one yield. jefferson did not send the letter in this form, but his draft identifies an important element of the consensus position that later emerged. even though the french privateering cases implicated “the interests, the rights and the dignity of the french nation,” the judiciary had the constitutional responsibility for vindicating france’s interests, because the cases also involved “questions of property between individuals.” on june , one week after genet wrote to jefferson, judge richard peters, the federal district judge in philadelphia, ruled that the district court lacked jurisdiction in the case of the william. jefferson sent his reply to genet after the district court issued its ruling. in that letter, jefferson told genet: “the persons who reclaimed the ship william as taken within the limits of the protection of the united states, having thought proper to carry their claim first into the courts of admiralty, there was no power in this country which could take the vessel out of the custody of that court, till it should decide, itself, whether it had jurisdiction or not of the cause.” jefferson’s reply is noteworthy for two reasons. first, if an individual files an in rem action in an admiralty court, and the court seizes a vessel on that basis, the executive has no power to order the court to release the vessel, notwithstanding french protests that the seizure violates u.s. treaty obligations owed to france. second, questions about the jurisdiction of u.s. courts were matters to be decided by the judicial branch, without interference from the executive branch. letter from citizen genet, minister of the republic of france, to mr. jefferson, secretary of state, june , , i aspfr, at . see infra notes - and accompanying text. draft letter from thomas jefferson to edmond charles genet, june , , papers of thomas jefferson, supra note , at - . see papers of thomas jefferson, supra note , at . findlay v. the william, f.cas.

(d. penn. ). f.cas. (d. penn. ). decree on the admiralty side of the district court of new york, in which the rights of sovereignty and neutrality concerning captures within neutral bounds; and the treaty of amity and commerce between france and the united states, and the jurisdiction of the neutral courts, as far as they are respectively connected with that subject are considered ( ) (available in microfilm) (copy on file with author) [hereinafter, the catharine]. all page references for the catharine refer to the author’s copy. see vi dhsc, supra note , at - . the french captors alleged that the betsey was british property, and hence subject to seizure as enemy property. see plea to the jurisdiction, reprinted in vi dhsc, supra note , at - . the french refused to participate in judicial proceedings in the catharine. hence, the summary of arguments adduced by french captors is based on the other three cases. findlay v. the william, f.cas. , (d. penn. ). saint louis university law journal jurisdiction to decide whether a captured vessel is a lawful prize. the district courts in the william, the fanny, and the betsey all accepted this argument, and agreed that the law of nations precluded the exercise of jurisdiction by u.s. courts. second, the french captors invoked article of the treaty between the u.s. and france as a bar to jurisdiction. the treaty stipulates: it shall be lawful for the ships of war of either party & privateers freely to carry whithersoever they please the ships and goods taken from their enemies . . . nor shall such prizes be arrested or seized, when they come to and enter the ports of either party; nor shall the . . . officers of those places . . . make examination concerning the lawfulness of such prizes . . . .” the treaty appears to bar in rem jurisdiction over the prizes (“nor shall such prizes be arrested or seized”), as well as subject matter jurisdiction over the dispute (precluding officers from making “examination concerning the lawfulness of such prizes”). hence, the french captors relied heavily on article to support their arguments against the jurisdiction of u.s. courts. however, of the four district court decisions under review here, the fanny was the only case in which the court gave much weight to the treaty argument to support its conclusion that it lacked jurisdiction. in contrast, the district court in the catharine expressly rejected the french interpretation of the treaty, concluding that the word “prizes” in article refers only “to captures on the high seas, according to the rights of war,” and not to captures in neutral territory. in addition to arguments based on the law of nations and the treaty with france, the french captors also argued, in effect, that the ship owners were not the proper plaintiffs to bring these claims. in their view, the allegation that a seizure occurred in neutral territory, if true, “did not give rights to [private] parties at war, but merely affected the neutral nation.” therefore, “the parties libellants . . . had no power to sue and recover on the point of violation of territory.” the district courts in the fanny and the catharine agreed with this argument: “i can find no sufficient reason for reducing the violation of a territory to the level of a private injury against an individual id. see the william, f.cas. at (“affairs of prizes are only cognizable in the courts of the power making the capture”); the fanny, f.cas. at (“neutral courts . . . are not clothed with authority to vindicate or carry on national contests”); the betsey, vi dhsc, supra note , at (“questions relative to such captures, as prize, can only be determined by the admiralty-courts belonging to that power, whose subjects make the capture.”). treaty with france, supra note , art. . see the william, f.cas. at ;

) “[t]hat by the law of nations, the courts of the captor can alone determine the question of prize, or no prize”; and ) that “the the catharine, supra note at . see also the fanny, f.cas. at . the william, f.cas. at . see also the fanny, f.cas. at (acknowledging “that a capture in a neutral territory was an offense to the neutral . . . [b]ut this is a matter of state policy, not of judicial proceeding.”). the betsey, vi dhsc, supra note , at . see also the catharine, supra note , at - ; the fanny, f.cas. at - ; the william, f.cas. at (“when two powers have any difference between them, the affair must be treated by negotiation, and not through the instrumentality of their courts of justice”). see sloop betsey, u.s., at - . an act to establish the judicial courts of the united states, sec. , stat. , - (sept. , ). u.s., at - . see id. at - . id. at . id. at - . id., at . saint louis university law journal interference of the american courts will be a manifest violation of the seventeenth article of the treaty with france.” the supreme court did not rule expressly on any of these arguments. even so, the court did hold expressly “that the district court of maryland . . . has jurisdiction competent to enquire, and to decide, whether, in the present case, restitution ought to be made to the claimants.” in so holding, the court implicitly rejected all three of the aforementioned arguments against jurisdiction. thus, to understand the reasoning behind the court’s decision, it is helpful to consider the appellants’ reply to each of these three points. first, the appellants noted that article of the treaty, by its terms applies only to “the ships and goods taken from their enemies.” therefore, they argued, “being in the affirmative, as to enemies, it affords a strong implication of a negative as to neutrals.” in other words, assuming that article limits the jurisdiction of u.s. courts, the limitation does not apply to cases, like sloop betsey, where the libellants claim that the captured vessel is neutral property. in such cases, the district court can exercise jurisdiction at least for the limited purpose of determining whether the captured vessel belongs to a neutral country, or a nation at war with france. by holding that the district court had jurisdiction in sloop betsey, the supreme court implicitly accepted this argument. strictly speaking, though, the court’s decision in sloop betsey did not address the treaty-based objection to jurisdiction in cases like the william, the fanny, and the catharine, where the libellants alleged that that the privateers seized enemy property in u.s. territorial waters. second, the appellants effectively conceded that, under the law of nations, the prize courts of the captor’s nation have exclusive jurisdiction to condemn a captured vessel as a lawful prize. nevertheless, the libellants had argued in the district court that although “the power to condemn belongs properly to the nation of the captor . . . the case before the court is not of a libel to condemn, but of a libel for acquittal and restitution; and . . . the courts of a neutral nation may sustain such a libel.” in other words, under the law of nations, the courts of a neutral nation cannot exercise jurisdiction over a prize case filed by a privateer who seeks a judgment that the captured vessel is a lawful prize, but they can exercise jurisdiction over a marine trespass case filed by the owner of a id., at . the french appellees added: “to decide in opposition to a compact, so unequivocal and unambiguous, would endanger the national tranquility, by giving a just and honorable cause of war to the french republic.” id., at - . this statement proved to be prophetic, because french allegations that the u.s. repeatedly violated article ultimately became a key factor that led to the so-called “quasi-war” between the u.s. and france. see infra note and accompanying text. id. at . treaty with france, supra note , art. . u.s. at . in a letter to gouverneur morris, then the u.s. ambassador to france, jefferson contended that article applied only to

waters, like neutral vessels, would be outside the scope of article . vi dhsc, supra note , at . judicial foreign policy: lessons from the s captured vessel who seeks restitution of the captured property. by holding that the district court had jurisdiction in sloop betsey, the supreme court implicitly accepted this argument. in contrast to the treaty argument discussed above, this argument applies equally to cases in which a libellant alleges that a privateer captured enemy property in neutral territory. finally, the appellants devoted most of their argument to showing that, under the u.s. constitution, the judicial branch, not the executive branch, is responsible for adjudicating cases like sloop betsey. the appellees argued that the alleged injury “is an attack upon the sovereignty of sweden,” and that therefore the individual libellants must seek redress from the sovereign. the appellants replied as follows: [t]he legislative, judicial, and executive powers . . . in the contemplation of our constitution, are each a branch of the sovereignty. . . . the constitution designates the portion of sovereignty to be exercised by the judicial department; and . . . renders it sovereign, as to determinations upon property, whenever the property is within its reach . . . to the judicial, and not to the executive, department, the citizen, or subject, naturally looks for determinations upon his property.” by holding that the district court had jurisdiction in sloop betsey, the supreme court endorsed the view that the wartime capture of private property implicated not only sovereign rights, but also private rights, and that disputes about private rights were properly directed to the judiciary, not the executive branch. the presentation of appellants’ argument on this point by the supreme court reporter, alexander dallas, is not as lucid as it might have been, but dallas’ report of the case does show that they made this argument. see dall. at . the court’s opinion states “that every district court in the united states, possesses all the powers of a court of admiralty, whether considered as an instance, or as a prize court.” id. at . in adjudicating a marine trespass case, like sloop betsey, the district court was sitting as an instance court to decide, as the appellants stated, the question of “[r]estitution or no restitution.” id. at . however, the implication of the supreme court’s statement is that, once convened as an instance court, the district court also has the jurisdiction “to try every incidental question,” id. at , including the question whether the seizure of the vessel was legal under the law of nations (which would ordinarily be tried in a prize court). professor casto contends that the supreme court’s resolution of this issue was inconsistent with “settled legal doctrine.” see casto, supra note , at . granted, there was an established rule under the law of nations that the question of “prize or no prize” was to be decided by the courts of the captor’s nation. however, as jefferson noted six months before the court decided sloop betsey, the law of nations also obligated the united states to extend its protection to foreign vessels in u.s. waters. see letter to gouverneur morris, aug. , , papers of thomas jefferson, supra note , at , - . in effect, the court decided in sloop betsey that the u.s. obligation under the law of nations to protect neutral shipping took precedence over the rule that would otherwise have barred the exercise of u.s. jurisdiction. this decision was consistent with the position adopted by the u.s. executive branch. in this author’s view, the court’s decision was a reasonable way to reconcile two conflicting rules of international law, although it would have been preferable if the court had explained its rationale. u.s. at - . id. at . in several of the french privateer cases, the privateers detained the captain and crew of the captured vessels as prisoners. the appellants in sloop betsey argued that the necessity to decide on the detention of prisoners was another reason why the case should be resolved by the judiciary, not the saint louis university law journal the court’s decision in sloop betsey could be interpreted narrowly to mean only that federal district courts have jurisdiction to adjudicate cases in which libellants allege the capture of a neutral vessel. however, as discussed in part iv below, the courts subsequently interpreted sloop betsey to mean that federal district courts had jurisdiction to entertain all claims of illegal seizures by french privateers. hence, sloop betsey was significant because it enabled france’s enemies to utilize the u.s. judicial system to file in rem actions alleging unlawful captures by french privateers. when ship owners filed in rem actions, the courts would seize the captured vessels and force the privateers to defend their property claims in court, thereby disrupting the privateers’ naval warfare activities. in sum, when the french attempted to gain a tactical military advantage by extending the battlefield to u.s. ports, their enemies responded by forcing france to fight the war in u.s. courts. by holding that the judicial branch, not the executive branch, was the proper forum for the resolution of these disputes, the supreme court facilitated the implementation of this strategy by france’s enemies. . the role of congress: the court held explicitly in sloop betsey that federal district courts had jurisdiction over claims involving captures of neutral vessels. the decision also implied that courts had jurisdiction over claims involving captures in u.s. territorial waters. to remove any possible ambiguity on that point, congress enacted legislation in june stipulating “[t]hat the district courts shall take cognizance of complaints by whomsoever instituted, in cases of captures made within the waters of the united states, or within a marine league of the coasts or shores thereof.” with this legislation, congress endorsed the view, already adopted by the supreme court and the executive branch, that the federal courts were a proper forum for resolving claims by individual ship owners that their ships had been captured unlawfully by french privateers. iv eighteenth century lawfare: from june to feb. after congress enacted the june legislation, there was a distinct change in the nature of the claims raised by ship owners who challenged the legality of captures made by french privateers. before june , the ship owners generally alleged that the privateers had violated the law of nations by capturing a neutral vessel, or by making a capture in u.s. territorial waters. after june , the ship owners generally alleged that the privateers had violated federal statutes by outfitting their vessels in u.s. ports, and/or by recruiting u.s. citizens as crew members. although the june ’ legislation prohibited outfitting of privateers in u.s. ports and recruitment of u.s. citizens, it did not authorize private lawsuits to enforce those rules, nor did it explicitly authorize federal courts to exercise jurisdiction over such claims. moreover, it is debatable whether the executive branch. see id. at (“and shall even american citizens be detained as prisoners in our own harbours, depending for their liberty upon the will of a secretary of state?”). it is unclear whether, and to what extent, the supreme court may have been swayed by this argument. an act in addition to the act for the punishment of certain crimes against the united states, june , , section , stat. , . judicial foreign policy: lessons from the s french privateers were violating the law of nations by recruiting u.s. citizens or by outfitting their ships in u.s. ports. . part iv examines the u.s. response to this second wave of french privateering cases in the period from june to february , when the supreme court decided the last french privateering case. during this period, the supreme court decided cases related to french privateering activities in the u.s. to appreciate fully the significance of those cases, it is necessary to view them simultaneously from three different angles. first, the privateering cases involved disputes between private parties over ownership of private property. second, the cases involved an ongoing diplomatic dispute between the u.s. and france over the proper interpretation and application of article of the treaty with france. third, the cases involved a tactical ploy by britain and other enemies of france to utilize the u.s. judicial system to harass french privateers and to undermine france’s naval warfare strategy (which relied heavily on the use of privateers). the distribution of decision-making responsibility during this period can be summarized briefly as follows. the federal judiciary was the primary decision-maker with respect to the major issues raised by the french privateering cases. the executive branch performed two main functions during this period: it listened to french grievances when french diplomats complained that u.s. courts were violating article ; and it explained u.s. judicial decisions to french diplomats in an attempt to justify those decisions. meanwhile, congress did not enact any significant legislation related to french privateering between june ’ and feb. ’ . this division of decision-making responsibility stemmed, in part, from a failure to view the cases from all three angles mentioned above. the u.s. government viewed the cases primarily as disputes about private property; that is why the judiciary took the lead role in resolving the cases. the executive branch was well aware of french grievances about violations of article , but the executive trusted the judiciary to address those grievances in the ordinary course of litigation. the analysis suggests that judicial decision-making in the privateering cases was a key factor that contributed to the deterioration of u.s. diplomatic relations with france. france became increasingly agitated by judicial decisions that, in its view, not only violated article , but also interfered with france’s naval strategy by disrupting the activities of french privateers. moreover, france was exasperated by the executive’s refusal to intervene in ongoing judicial proceedings. by the end of , france had initiated a series of measures – intended partly to retaliate against the united states for alleged violations of article – that ultimately led to the outbreak of the so-called “quasi-war” between the u.s. and france. see infra notes __ and accompanying text. jennings v. brig perseverance, u.s. ( dall.) (feb. ). see infra part iv.b (presenting an overview of the cases). it is clear from the diplomatic correspondence of the era that france’s allegation that the u.s. repeatedly violated article was one of the key french grievances that led to the quasi-war. see, e.g., letter from mr. adet, minister plenipotentiary of the french republic, to mr. pickering, secretary of state of the united states, nov. , , reprinted in i aspfr, at - ; letter from ch. de la croix to the saint louis university law journal the analysis in part iv is divided into four sections. the first section explains how france’s enemies utilized the u.s. judicial system to thwart france’s naval warfare strategy. the second section provides an overview of the privateering cases decided by the supreme court during this period. the third section provides case studies of two cases to show how judicial decisions in the privateering cases became a primary focus of u.s. diplomacy with france. the final section contends that judicial decision-making by u.s. courts was one of three key factors that ultimately persuaded french privateers to stop bringing their prizes to u.s. ports. a. litigation as a means of warfare in march , the council on foreign relations defined “lawfare” as “a strategy of using or misusing law as a substitute for traditional military means to achieve military objectives.” the report described lawfare as a “new phenomenon” and warned of associated dangers. in fact, lawfare is not a new phenomenon. in the period from to , great britain (and to a lesser extent france’s other enemies) successfully utilized a lawfare strategy to counter the military maneuvers of french privateers who were using american ports as a base of operations for naval warfare. between june and february , the supreme court decided cases in which british consuls filed in rem suits seeking restitution of british merchant vessels captured by french privateers. the british consuls lost of those cases. even so, benjamin moodie, the british consul in south carolina who filed of the cases, was quite satisfied with the results. since these were in rem actions, the courts typically retained custody of the captured property (or the funds from sale of the property) for - months while judicial proceedings were pending. thus, by filing in rem actions in u.s. district courts, and then filing appeals in the circuit courts and the supreme court, the libellants successfully detained the privateers’ property for extended periods of time, and made it difficult for the privateers to initiate additional attacks on enemy merchant vessels. hence, in april , when most of these cases were pending before the minister plenipotentiary of the united states of america, dec. , , reprinted in i aspfr, at - . however, the leading history of the quasi-war, in providing a summary of french grievances, curiously omits any reference to the alleged u.s. treaty violations. see alexander deconde, the quasi-war: the politics and diplomacy of the undeclared war with france, - ( ), pgs. - . council on foreign relations, lawfare: the latest in asymmetries (march , ), available at http://www.cfr.org/publication.html?id= . these thirteen cases include four published decisions and ten unpublished decisions. the published decisions are: moodie v. ship phoebe anne, u.s.

(d.s.c. ). when the captors brought the magdalena into charleston, joost jansen, the dutch master of the magdalena, filed a libel on behalf of the dutch ship owners seeking restitution of the captured vessel and its cargo. jansen alleged that the two ships claiming to be french privateers were owned by u.s. citizens, and that ballard and talbot were both u.s. citizens. see id. at - . talbot invoked the law of nations and article of the treaty with france as a bar to the jurisdiction of u.s. courts. the district court ruled in favor of the dutch owners in august . the circuit court affirmed that decree in november , and the supreme court affirmed in august . four supreme court justices wrote separate opinions in talbot: justice iredell’s opinion provides the clearest statement of the court’s rationale for rejecting talbot’s objection to the jurisdiction of u.s. courts. in his view, although article precludes u.s. courts from making “examination concerning the lawfulness of such prizes,” the courts must still examine the facts to ascertain whether a case fits within the scope of the exemption granted by the treaty. moreover, the treaty term “privateers” refers only to lawfully commissioned privateers. therefore, the district courts must first decide whether a privateer is lawfully commissioned before concluding that article precludes them from exercising jurisdiction. for a detailed account of the case, see vi dhsc, supra note , at - . see supreme court minutes, feb. , , reprinted in i dhsc, supra note , at . this was an in rem action against a british vessel, the favorite, captured by the french privateer la parisienne in march . the libellant, benjamin moodie, was the british consul in south carolina. he filed the action in the u.s. district court in south carolina in march on behalf of the british ship owners. the district court ruled in favor of the french captors in april . that decree was affirmed by the circuit court in november , and by the supreme court in february . information about the favorite is derived from bee’s admiralty reports, supra note , at ; jackson, supra note , at - ; and from the author’s research in the supreme court archives. see supreme court minutes, feb. , , reprinted in i dhsc, supra note , at . this was an in rem action against a british vessel, the caesar, captured by the french privateer la parisienne in december . the libellant, john wallace, was the british consul in georgia. he filed the action in the u.s. district court in georgia in january on behalf of the british ship owners. the district court ruled in favor of the french captors in february . that decree was affirmed by the circuit court in may , and by the supreme court in february . information about the caesar is derived from vii dhsc, supra note , at - . see supreme court minutes, march , , reprinted in i dhsc, supra note , at - . this was an in rem action against a british vessel, the mermaid, captured by the french privateer general laveaux in january . the libellant, benjamin moodie, was the british consul in south carolina. he filed the action in the u.s. district court in south carolina in february on behalf of the british ship saint louis university law journal britannia, moodie v. brig eliza( ), moodie v. brig tivoly, moodie v. brig eliza( ), moodie v. snow potowmack, and don diego pintado v. ship san joseph. in all ten cases, the french privateers scored consistent victories in the district court, the circuit court and the supreme court. owners. the district court ruled in favor of the french captors in april . that decree was affirmed by the circuit court in october , and by the supreme court in march . information about the mermaid is derived from vii dhsc, supra note , at - ; jackson, supra note , at - ; and from the author’s research in the supreme court archives. see also british consul v. the mermaid, f.cas.

vengeance judicial foreign policy: lessons from the s overall, the french privateers prevailed in of the cases where ship owners and/or their agents filed in rem suits seeking restitution of enemy merchant vessels captured by french privateers. in of those cases, the courts at all three levels – district courts, circuit courts and supreme court – ruled in favor of the french privateers. this point is significant because it lends credence to the french allegation that these were frivolous lawsuits filed for the purpose of harassing the privateers and thwarting the accomplishment of their military objectives. british consuls were the named plaintiffs in of the cases, and a spanish vice-consul was the named plaintiff in one other case. as a formal matter, the consuls were merely representing the private interests of merchant ship owners. however, as a practical matter, the active participation of the british consuls also lends credence to the french allegation that the british government was pursuing a conscious “lawfare” strategy to disrupt the military activities of french privateers. it is also noteworthy that of the cases involved british merchant vessels, and the french privateers won of those cases. assuming that the british strategy was to deny the privateers any financial gain from their lawful prizes while the litigation was pending, that strategy was quite effective. the courts retained control of the captured property, or the money obtained from the sale of that property, until there was a final disposition of the cases by the supreme court. in descending order, the time lag between the initial libel and final disposition by the supreme court in the british cases where the privateers prevailed was as follows: perseverance ( months), eliza( ) ( months), tivoly ( months), alfred ( months), phoebe anne ( months), betty cathcart ( months), britannia ( months), potowmack ( months), phyn ( months), mermaid ( months), caesar ( months), eliza( )

( ). the dates of the libels and the supreme court decisions are included in notes - , supra. saint louis university law journal finally, the attentive reader may have noted that of the cases were filed in the u.s. district court in south carolina. in the s, the exclusive venue for an in rem admiralty action was the place where the ship was located. french privateers routinely brought their prizes to charleston, south carolina, in part because charleston “in the s was a bastion of francophilia.” once a privateer brought his prize to charleston, a ship owner who wanted to file an in rem action to obtain restitution of the captured prize had no choice but to file his claim in the south carolina district court. in those days, there was a single judge assigned to each federal district court. thomas bee was the federal district judge for the district of south carolina. as discussed more fully in the next section, judge bee’s decisions were very influential in shaping the law related to french privateers because he decided most of the french privateering cases at the district court level, and the supreme court affirmed most of those decisions without any written opinion. c. two case studies recall that the supreme court held in sloop betsey that federal district courts have jurisdiction over claims for restitution by ship owners who allege that a privateer captured a neutral ship. additionally, congress enacted legislation granting district courts jurisdiction over claims for restitution in cases where privateers captured enemy ships in u.s. territorial waters. however, the cases where ship owners and/or their agents filed in rem suits seeking restitution of enemy merchant vessels did not fit within either of these jurisdictional principles because all cases involved captures of enemy ships on the high seas. in these cases, the libellants generally raised two types of allegations. first, they alleged that the privateers had been illegally outfitted in u.s. ports, or had augmented their forces in u.s. ports. second, they alleged that the privateers were owned by americans, commanded by u.s. citizens, or manned by u.s. citizens. the legislation enacted by congress in june created criminal penalties for individuals who accepted a commission from a foreign state, enlisted to serve on a foreign privateer, outfitted a foreign privateer in a u.s. port, or augmented the force of a privateer in a u.s. port. however, congress did not explicitly authorize private claims for restitution to enforce these laws, nor did congress explicitly authorize federal courts to exercise jurisdiction over these types of claims. see supra notes -

(the british libellants alleged that the sale to moreau was fraudulent; hence, the ship was still american.) by the end of the year, the cygnet had been re-named the general laveaux. the general laveaux sailed as a privateer from saint-domingue in late with a french commission. it captured the mermaid in january . justice iredell’s analysis is divided into three parts. first, he considered the allegation that the privateer had been “fitted out & equipped in america.” justice iredell wrote: “admitting this fact, this only a local offence against the neutral nation . . . does not in itself divest the property. . . . if therefore truly & bona fide alienated, she became french property, & as such the owners under a real french commission had a right to cruise, & bringing her prizes into american ports entitled to the protection of the art.” the implication of this statement is clear. if a british libellant seeks restitution of a captured prize on the grounds that the french privateer was illegally outfitted in u.s. ports, the court should dismiss the claim without addressing the merits, because illegal outfitting, even if proven, would not invalidate the legality of a subsequent capture made by a french privateer with a valid commission. moreover, article precludes u.s. courts from inquiring into the lawfulness of the capture. if this analysis is correct, judge bee violated article by examining the merits of the illegal outfitting claim, even though he eventually relied on article as a basis for dismissing the libel. second, justice iredell considered the argument that the june legislation provided for forfeiture of a vessel that was illegally outfitted in u.s. ports. consistent with the preceding analysis, he wrote: “admitting a forfeiture had incurred by a special law of the u.s., this would not invalidate a prize taken by her after a bona fide alienation to a real french citizen in another country.” iredell agreed that the u.s. could institute a forfeiture action against the privateer, but forfeiture of the privateer “does not necessarily infer a forfeiture of all the prizes which such vessel might take.” moreover, “a fair capture under a real french commission by real french citizens would article of the treaty with france expressly grants french ships a right to carry out repairs in u.s. ports. see treaty with france, supra note , art. . see james iredell’s notes for a supreme court opinion, march , , reprinted in vii dhsc, supra note , at -

[t]his prize has been seized, and under the pretext that the privateer sans pareil had been armed in the ports of the united states. if this pretext had been really alleged, a more glaring injustice and more palpable falsehood could not have been disguised . . . but, perhaps, as has frequently happened, they have only wished to discourage and fatigue the captors, by injuring the prize, from the length of time required for obtaining the decision, which they will retard by a thousand unfair expedients. in this case, sir, it is at length time to take a determination which will secure the interests of the captors, who, without this precaution, will be always injured, whatever may be the determination of the courts; they will be affected, first by the loss of time; secondly, by the expenses in prosecuting this business; and, lastly, by waste in the merchandises and vessels which they shall have taken.” thus, from france’s perspective, even when french privateers ultimately prevailed in legal proceedings, they were still the losers, because the legal proceedings cost them valuable time and money. moreover, the loss of time and money adversely affected france’s strategic interests by providing economic disincentives to privateering, thereby making it harder to recruit additional privateers. on september , , secretary randolph wrote to fauchet to inform him that he had “urged the governor of rhode island to report, without delay, the case of the prize letter from mr. fauchet, minister plenipotentiary of the french republic, to mr. randolph, secretary of state, aug. , , i aspfr, at . id. id. it bears emphasis that the economic disincentive to privateering was not an ordinary incident of naval warfare during this era. in the “typical” naval conflict, a privateer could obtain a speedy judgment by bringing a captured vessel to a prize court in his home country; this process rarely led to protracted litigation. however, in the american theater of the war between france and britain, the british were able to exploit the geographic distance between the u.s. and the nearest french prize courts by subjecting french privateers to protracted litigation when they brought their captured prizes to u.s. ports. saint louis university law journal taken by the privateer sans pareil.” randolph added: “be assured, sir . . . that the government of the united states will not suffer the acquisitions of the french privateers to be wrested from them, without adequate cause; nor yet, that they should be wantonly vexed by unjust detentions.” two days later, on september , governor fenner ruled in favor of the french privateers and “ordered the perseverance delivered to” the french captors. on september , randolph wrote to fauchet to report the good news. however, the communication from governor fenner to secretary randolph to ambassador fauchet lagged far behind the pace of actual events. the french captors sold the perseverance and its cargo on september , . however, before they could escape with the funds, the british owner, thomas jennings, “secured a monition requiring the united states marshal to retain the funds” and filed a libel in the federal district court. in the libel, jennings alleged two violations of the june ’ legislation enacted by congress. he claimed “that the sans pareil had been augmented in force” in charleston, south carolina, in violation of section of the statute, and that the sans pareil was “to an extent manned with americans,” in violation of section . he also alleged that none of the frenchman on board the sans pareil had a valid commission. for all these reasons, he claimed that the capture of the perseverance was illegal, and he sought damages to compensate him for the loss of the ship and its cargo. when fauchet learned that the british owner initiated judicial proceedings, after the governor of rhode island had already ruled in favor of the french captors, he was furious. on october , , fauchet wrote to randolph as follows: you announce to me that la perseverance, prize to the sans pareil, had been delivered to the captors by order of the governor of rhode island; in contempt of that decision the english agents have just created new difficulties . . . it is impossible, sir, for this state of things to continue much longer. you are sensible how necessary it will be to retrench from our treaty the article letter from mr. randolph, secretary of state, to mr. fauchet, minister plenipotentiary of the french republic, sep. , , i aspfr, at . see also letter from mr. randolph, secretary of state, to the governor of rhode island, sep. , , i aspfr, at (discussing the sans pareil, and noting that the french ambassador is concerned that “the ardor of french privateers [may] be dampened by the vexations which a seizure of their prizes may produce”). letter from mr. randolph, secretary of state, to mr. fauchet, minister plenipotentiary of the french republic, sep. , , i aspfr, at . vii dhsc, supra note , at - . in august – after several district courts had dismissed french privateering cases for lack of jurisdiction, and before the supreme court issued its decision in glass v. sloop betsey – the secretary of war had written to state governors to encourage them to adjudicate these cases. see id., at . that is why the british sought relief from governor fenner and why he agreed to perform a judicial function in this case. letter from mr. randolph, secretary of state, to mr. fauchet, minister plenipotentiary of the french republic, sep. , , i aspfr, at . vii dhsc, supra note , at . id. id. id. judicial foreign policy: lessons from the s which reciprocally permits the ships of war of the two nations to conduct to, and sell their prizes in, their respective ports, should this right become illusory and void by the difficulty thrown in the way of its execution. i proposed a method as simple as it is just, for putting an end to this tyrannical chicanery: this method was, to require security from those who prosecuted prizes as illegal. were this measure adopted, it would render our enemies less ingenious in their proceedings, and prevent them from bringing so many actions . . . i expect, sir, that the federal government will put an end to these persecutions by the mode i have proposed, or by any other which its wisdom may suggest.” randolph was evidently sympathetic to fauchet’s plea. nevertheless, he told fauchet pointedly that the executive branch could not intervene in ongoing judicial proceedings, and that the judiciary was the proper branch of government to resolve disputes between french privateers and british ship owners: if, however, individuals conceive that they have a legal claim upon her, and draw her before a court of law, the executive of the united states cannot forbid them. the plea, under [article of] the treaty, that the court has no cognizance of french prizes, will be admitted if it applies, and the person by whom the process is instituted will be liable to a judgment for costs and damages, if he fails in his proof. the bond, which you propose as a security against vexation, we have no power to demand, because the executive do not mean to interfere, without presumptive proof of title; and this presumption, when established, would seem to be a sufficient protection against being harassed. the courts have their forms . . . i am not authorized to make the arrangement proposed.” thus, randolph tacitly acknowledged that article barred the exercise of jurisdiction by u.s. courts in certain cases. however, the courts had to exercise jurisdiction for the limited purpose of deciding whether article applied. moreover, in randolph’s view, if fauchet wanted to offer suggestions about procedural innovations to minimize vexatious lawsuits, he should direct those suggestions to the judiciary, because there was no basis for the executive to intervene in the affairs of an independent branch of government. despite ambassador fauchet’s best efforts to assist the privateers who had a legitimate claim to the funds from the sale of the perseverance, the judicial process consumed almost two-and-a-half years. the french captors could not obtain access to letter from mr. fauchet, minister plenipotentiary of the french republic, to mr. randolph, secretary of state, oct. , , i aspfr, at . see letter from mr. randolph, secretary of state, to mr. fauchet, minister plenipotentiary of the french republic, oct. , , i aspfr, at (expressing his wish “that we were always able to administer immediate relief”). id. saint louis university law journal the funds until february , when the supreme court issued its final decision in jennings v. brig perseverance. d. the end of french privateering in the u.s. “by early november ,” french privateering activities in u.s. ports “had all but ceased.” there were three key factors that contributed to the decline of french privateering in the united states: the jay treaty, lawfare in u.s. courts, and geo- political developments in the caribbean. in the spring of , “the british had a stranglehold on french possessions in the caribbean.” since the british denied french privateers access to french ports in the caribbean, and the privateers did not want to carry their prizes across the atlantic to sell them in france, the best economic choice was to sell their prizes in u.s. ports. however, the strategic situation in the caribbean changed dramatically between june and late . france launched a successful attack against the british in guadeloupe in june . having re-established a foothold in the caribbean, france bided its time over the next several months. then, between march and june of , france launched a major offensive that led to a string of french victories in the caribbean. in july , the treaty of basel terminated hostilities between france and spain. by the end of , france and spain had become allies in a war against great britain. as a result of these developments, french privateers were able to take their prizes to french prize courts in the caribbean. these “new privateering opportunities” in the caribbean operated as a “magnet that drew the french privateers away from” the united states. the economic magnet of privateering opportunities in the caribbean combined with the financial drain imposed by british lawfare in u.s. courts to lure french privateers away from u.s. ports toward french ports in the caribbean. the privateers did not need to be financial wizards to calculate the costs and benefits of the two options. since the french could not operate prize courts in the united states, prizes sold in the united states without prior condemnation by a prize court invariably sold at a reduced price. moreover, if a commander brought his captured prize to a u.s. port, he could expect the gains from his business venture to be tied up in u.s. courts for - months. unless he had a cushion of cash reserves on hand, he would be unable to pay his crew, making it difficult, if not impossible, to hire crew for the next voyage. in u.s.

( ); united states v. peters, u.s. ( ). http://www.cfr.org/publication.html?id= judicial foreign policy: lessons from the s government is a party to most of the modern war on terror cases. moreover, both the legislative and executive branches encouraged active judicial involvement in the privateering cases in the s. in contrast, the legislative and executive branches have worked together in the past few years to minimize judicial involvement in cases arising from the war on terror. despite these differences, the privateering cases do offer an important pragmatic lesson that is still relevant today. according to the new york times, “people in britain and france told pollsters last spring that they had even less confidence in [president bush] to do the right thing in world affairs than they had in president vladimir putin of russia.” u.s. foreign policy cannot succeed if our key allies do not trust us to comply with our international legal obligations. the founders understood this: they wanted to convey a message to the world that the u.s. was committed to the rule of law in international affairs. in the s, the executive branch reinforced this message by deferring to the judiciary and allowing federal courts to decide key issues related to french privateering activities. in the current geopolitical situation, if the government wants to persuade u.s. allies that the united states is committed to complying with its international legal obligations, it can promote that objective by inviting judicial scrutiny of u.s. policies in the war on terror, at least in cases where those policies are intimately bound up with questions of international law and individual rights. in contrast, continued resistance to judicial oversight reinforces the belief, which is widely shared among the citizens of some of our closest allies, that the united states views international law with a mixture of contempt and indifference. political realists might explain the differences between the s and today as a function of political power. weak states are receptive to international law because it has the potential to constrain their stronger adversaries. strong states are less receptive because international law tends to equalize power imbalances among states, thereby reducing the comparative advantage of stronger states. the united states embraced international law in the s because it was a weak state; the u.s. is suspicious of international law today because it is a strong state. this explanation is fairly persuasive, as far as it goes. but it does not answer the key normative question: is it generally in the national interest of the united states to comply with its international legal obligations, and to be perceived as complying with those obligations? there is ample room for disagreement on this question, but a president who wants to persuade the world that the u.s. takes its international legal obligations seriously could advance that goal by encouraging a more active role for the federal judiciary in the implementation of u.s. foreign policy. see, e.g., hamdan v. rumsfeld, u.s.

assistant professor, ; associate professor, ; and professor . of the professors, at least ( %) were female. of the pd, at least ( %) were working at the institution from which they had received their training, and at least ( %) had the additional roles of vice chair, associate chair, or medical director. a total of individuals held endowed chairs as identified by departmental websites. only pd had active nih funding in (table ). the median h-index was (range, - ) but dropped to (range, - ) when those who served as both pd and chair were removed from the group. regarding the institution where pd received their training, and using a minimum of pd from a given institution, the following training programs represented the institutions that trained % of the pd at the time of the study: harvard (massachusetts general hospital in combination with the former joint center program, now the combined harvard radiation oncology training program), ;

and mayo college of medicine, / (table ). discussion these data provide basic information regarding some of the characteristics of current pd and department chairs. the data serve only as a simple “snapshot” for those currently in leadership positions and by no means take into consideration other objective factors or more intangible attributes. programs grow, may change in quality, and have changes in leadership and philosophy. lead- ership is often a dynamic process, with departments taking different directions based on the perceived needs of the depart- ment and institution at a given time. the data provide several interesting findings. a total of individuals serve the dual role of pd and chair, and % of the pd versus % of the chairs were md/phd. women constituted a higher proportion of the pd, at %, compared with % for chairs. rank was relatively evenly distributed among the pd. age was lower for pd than for chairs, and this would likely be ex- pected, given the experience usually required of those considered for chair positions. the h-index is used by many in an effort to more objectively document the productivity of a faculty member. it is often considered in the promotions process or in the endeavor to make a direct comparison between faculty members’ productivity. table institutions that trained at least chairs and program directors institution chairs program directors harvard university of chicago university of california, san francisco thomas jefferson university cleveland clinic university of pennsylvania washington university yale school of medicine mayo college of medicine there are several issues with the h-index, though, that should be considered. the index does not take into account the subject matter at hand and the contribution of any particular author, and authorship position is not accounted for. despite these issues, it remains an objective benchmark for academic productivity within and across specialties. in a study published in by choi et al ( ), the h-index was evaluated for faculty at radiation oncology training programs in the united states. the th percentile h-index for all faculty was , the median for female chairs was , and the median for male chairs was . the authors also found that there was a “breakpoint” between senior and junior faculty, with the breakpoint being an h-index of . in our analysis, the median chair h-index seems significantly higher at . this is likely a function of the period of time under study. scopus analyzes h- index based on publications from onward, so additional years in total are captured in the current report, compared with the report by choi et al ( ) that reviewed the h-index with a sample through . a study more recently published by svider et al ( ) reveals interesting comparisons. the authors analyzed the h-index for otolaryngology, and the sample was inclusive of , which provides a similar time reference to our study. a random sample of residency programs was used, and the h-index calculated for otolaryngology faculty from these programs. the authors found the following h-index by rank: assistant professor, . ; associate professor, . ; professor, . ; and chairperson, . . the authors then selected chairpersons from the same “set” of institutions used in their otolaryngology analysis. the h-index was then determined for chairpersons from neurosurgery, otolar- yngology, orthopedic surgery, general surgery, internal medicine, anesthesiology, and radiology at institutions, which were selected randomly. the h-index for the chairpersons was as follows: general surgery, . ; internal medicine, . ; neuro- surgery, . ; orthopedic surgery, . ; otolaryngology, . ; radiology, . ; and anesthesia, . . our data, from a larger sample, and not randomly selected, reveal a median h-index of for radiation oncology chairs. the mean from our data for comparison purposes was . hence, the mean h-index for chairs of radiation oncology likely tracks very closely with those chairs from general surgery and slightly higher than chairs of internal medicine. gender inequality remains an important issue, and the gap in gender equity for the leadership positions in our study is substantial. this may change in the future because there is somewhat more gender equity among current trainees and recent graduates ( ). conclusions the information may be of interest both to individuals considering leadership positions and to programs interested in establishing benchmarks for leadership positions. these findings also facilitate the evaluation of leadership trends over time and between specialties. references . aneja s, wilson ld, haffty bg, et al. national residency matching program (nrmp) results for radiation oncology: update. int j radiat oncol biol phys ;

pathology and labo- ratory medicine. under many circumstances, one can obtain a ph.d. in the biological sciences or finish a post- doctoral experience. on the other hand, it can seem like no time at all. the last five years reveal that america’s pop-culture idols carry on, american foreign policy is little altered, and nih funding remains depressingly flat. yet for us, five years marks the end of our stewardship of the american journal of pathology. as our terms at the ajp conclude, we are struck by how rewarding the past five years have been. the ac- complishments in this time are notable, from creating a scientific editor position to increasing reviews and other editorial content, arranging articles into subcategories, publishing the “power of ten”—the monthly report of the most-read ajp articles, and adopting a formal scientific integrity policy to disseminating ajp content through press releases, pubmed central, and publish-ahead-of- print. with these changes we believe that we have im- proved the value of the journal as well as enhanced the author experience. but beyond these efforts, we continue to believe that the greatest strength of the ajp is its commitment to unbiased peer review of the pathophysi- ologic mechanisms of disease. and just like the coca- cola company, we alter this time-tested formula at our own peril. the success of the journal’s initiatives manifests itself, in part, via the impact factor. although the ajp experienced a drop in impact factor, together with many other pathology journals, the ajp received a impact fac- tor of . , placing it again in the first position for gen- eral pathology journals. we believe this rebound is sus- tainable, as the ajp continues to be the most-frequently cited journal in the field, receiving over , citations in . of note, since the impact factor lags from date of publication to calculation, the prolonged effects of our changes in the last five years (good and bad) will extend into the next few years. however, the impact factor (largely unchanged since its inception half a century ago) faces strong competition from several emerging metrics that reflect modern journal usage, for example, revised pagerank score (red jasper) and eigenfactor (univer- sity of washington; http://www.eigenfactor.org/). interest- ingly, when using these new methodologies, ajp fares extremely well among pathology journals. while impact factor is important to the perceived suc- cess of the journal, our real success lies in publishing the strongest and most relevant science for our readers and the investigative pathology community as a whole. as a consequence of these lofty goals, we apologize to our colleagues who, perhaps more often than we would have wished, received rejection letters from us. as authors ourselves, we are not immune to the emotions such re- jection brings. with this as a guide, we rendered our decisions with utmost care and respect, without bias, and with only the scientific rigor of the journal in mind. it has only been with the assistance of our colleagues that we have maintained our high publication standards. we are grateful to all of the associate editors who have served with us during our tenure, drs. jeffrey cossman, patricia d’amore, lora ellenson, philip furmanski, mary hendrix, setsuo hirohashi, david hockenbery, dontscho kerjaschki, andrew lackner, kevin moore, brian nick- oloff, yasunori okada, charles parkos, sem phan, kevin roth, and jeffery saffitz. we extend a special thanks to dr. peter ward for taking the lead as special associate editor with responsibility for originating and implementing our high-profile review series biological perspectives. to- gether with our editors, the editorial board represents the breadth of expertise and experience in pathobiology, and we appreciate their hard work and dedication to the journal. we also reflect, with happiness, on the positive attributes the three managing editors have brought to the consistent quality of ajp over these five years as well as the editorial team in bethesda, md, and at the university of alabama at birmingham. we are aware that we may be the last of a certain kind of editor. the american society for investigative pathol- ogy, our publisher, has for decades selected its editors from the leadership of american academic departments of pathology. in a bold stroke, the asip selection com- mittee has chosen a new editor-in-chief who is outside that mold. dr. michael p. lisanti, who begins his term with the next issue, is professor of cancer biology at jefferson medical college of thomas jefferson university and jef- ferson’s kimmel cancer center in philadelphia, pa, and is among the top most-cited scientists in biology and biochemistry (thomson’s essential science indicators). he brings a depth of investigative experience and a breadth of research interests and knowledge in a variety of subject areas. given that greater than % of our the american journal of pathology, vol. , no. , june copyright © american society for investigative pathology doi: . /ajpath. . submissions are from corresponding authors who are not from pathology departments, dr. lisanti represents the diversity of our readers and authors. we wish him the very best of success as he steers this publication forward. as for our time at the helm, it has been a pleasure and an honor to serve the american journal of pathology. we thank our authors, reviewers, and readers for having allowed us to serve you over this last half decade, and we trust you will continue to support the journal by submit- ting your best scholarship for consideration, by agreeing to thoughtfully review submissions, and by continuing to read the ajp. finally, we remain grateful to the efforts of the editors, editorial board, and editorial office, as well as the support of asip leadership. the last five years have been, for us, quite a ride! reference . journal

isoform specific n terminus of vdac is dispensable for tbid induced cytochrome c release tuesday, february , a agent colchicine that is known to increase free tubulin, mitochondrial potential, as measured by tetramethylrhodamine methyester (tmrm) uptake, decreased. inhibition of pka activity with h increased mitochondrial potential and, fur- thermore, reversed mitochondrial depolarization induced by colchicine. to fur- ther explore a role vdac-tubulin interaction in cell proliferation and survival, we studied the effect of erastin, the selective anti-tumour agent involved in the ras-raf-mek signalling pathway, on vdac blockage by tubulin. we found that erastin reverses tubulin blockage of vdac isolated from hepg cells, pro- moting the unblocked state of the channel. our findings suggest a novel func- tional link between serine/threonine kinase signalling pathways, mitochondrial respiration, and highly dynamic microtubule network which is characteristic of carcinogenesis and cell proliferation. -plat the isoform specific n terminus of vdac is dispensable for tbid induced cytochrome c release shamim naghdi , peter varnai , laszlo hunyady , gyorgy

hungary. vdac proteins represent a main component of the outer mitochondrial mem- brane (omm). the vdac family is composed of isoforms with more than percent similarity. although their primary role was known to be in ion and me- tabolite transport between mitochnodria and cytosol, it has been discovered that vdacs are involved in apoptotic pathways. we have recently found that spe- cifically the vdac isoform is needed for tbid-induced cytochrome c release, due to its role in supporting bak insertion to the omm (roy et al. . embo rep. : - ). sequence analysis of the mammalian vdac isoforms shows a unique n terminal end in vdac , which is likely to be exposed to the cyto- plasm. to test the functional significance of this n terminus, the first amino acids were removed from vdac or were added to vdac . vdac -/- mef cells that are resistant to tbid, were rescued with these constructs and cyto- chrome c release was monitored in permeabilized cells by single cell imaging and immunoblotting. these studies revealed that cytochrome c release upon tbid application is effectively supported by both full length vdac and the vdac n-terminal deletion mutant. furthermore, vdac extended by the n terminus of vdac failed to restore cytochrome c release in vdac -/- mefs. thus the n terminus of vdac seems to be dispensible for tbid- induced omm permeabilization. currently, we are designing different muta- tions which target some addititional unique sequences in vdac to find the specific domain that is essential for tbid induced cytochrome c release. -plat patch-clamp analysis of mitochondrial ca d uniporter in different tissues francesca fieni, yuriy kirichok. ucsf, san francisco, ca, usa. the mitochondrial ca þ uptake has been recognized as a central player in cel- lular pathophysiology for decades. pathways of ca þ transport across the inner mitochondrial membrane (imm) were investigated indirectly with biochemical techniques and most recently by applying the patch clamp technique to mito- plasts isolated from mammalian systems. patch-clamp recording of the imm have proved to provide an unambiguous picture of mitochondrial ca þ uptake under strictly controlled conditions. in this study, we evaluated and compared the biophysical properties of mito- chondrial ca þ uptake in different mouse tissues. freshly isolated mitoplasts from mouse heart, skeletal muscle, liver, kidney, spleen and brown adipose tis- sue were patch clamped in the whole-mitoplast configuration. voltage step and ramp protocols covering the whole range of physiological potentials were ap- plied to elicit the inwardly rectifying ca þcurrent sensitive to rur known as mcu. the distribution of mcu current densities between tissues was as fol- lows: spleen > brown adipose tissue z skeletal muscle > kidney > liver >> heart. interestingly, mcu current density in heart was about times smaller than in skeletal muscle. our results support the view of a differential tissue activity of mcu, which can be explained by either a different distribution of mcu channel and/or by a different expression of its regulatory subunits confer- ing various modes of physiological regulation. further on, in order to investigate the putative direct contribution of uncou- pling protein isoform and (ucp / ) to the uniporter, we investigated mcu properties in wild type (wt) mouse tissues where these two proteins have been found to have a major role and compared its properties in the corre- spondent tissues of ucp and ucp ko mice. we found no significant differ- ences in

various forms of stress in the heart, and this is often accompanied by mitochondrial dysfunction. a putative source of mitochondrial dysfunction is sr-mitochondrial stress and the ensuing mitochondrial ca þ overload. to test this possibility, first we isolated mitochondria from chronic ethanol-fed ( months) and paired control rats, and documented ethanol- dependent sensitization to ca þ and ros-induced permeabilization. to evalu- ate the ultrastructural basis of the mitochondrial impairments, we performed transmission electron microscopy (tem) and electron tomography studies of left ventricular muscle. the overall ultrastructure of the myocytes became less organized in the ethanol-fed condition. also, a considerable fraction of the mitochondria lost the highly ordered structure of the cristae and showed an increase in the cross-sectional area. however, the size of the sr- mitochondrial associations and the gap-width at the interface was unchanged. evaluation of the sr-mitochondrial tethers by electron tomography indicates that they occur in clusters and display heterogeneity in length, as previously re- ported for er-mitochondrial tethers in normal rat liver (csordas et al, , j cell biol, : ). overall tether length distribution appears to be unaltered by alcohol ingestion. analyses of effects of alcohol ingestion on tether membrane-surface density and structural classes (linear, v, y and more com- plex shapes) is in progress, as is d analysis of ser and mitochondrial inner- and outer-membrane topologies.

vascular quality of life questionnaire (vascuqol) in languages conway k , uzun v , girod i , morgan m , koch p mapi research institute, lyon, france; mapi values, lyon, france; lewisham hospital, london, uk; boehringer ingelheim, ingelheim, germany introduction: measuring quality of life (qol) has become a vital part of assessing lower limb ischemia and peripheral vascular disease in international studies. the -item vascuqol was developed in uk english and investigates domains: symptoms, pain, activities, social life and emotional state. prior to use in an international trial the measure underwent linguistic validation in lan- guages. methods: a qol specialist coordinated the translation process in each target country using the fol- lowing methodology: ) two forward translations by pro- fessional, native speaking translators of the target lan- guage fluent in english; ) comparison and reconciliation of the translations by a qol specialist and translators; ) backward translation by a native english speaker; ) comparison of the source and backward versions; ) re- view of the translation by a clinician in each country; ) comprehension test in a sample target population; ) in- ternational harmonization. results: linguistic and conceptual issues emerged when translating idiomatic phrases and response scales. linguistic equivalents had to be found for expressions such as “being (or becoming) housebound” and “social activities”. the notions of “discomfort”/“distress” did not have direct equivalents in some languages where a single notion had to be used. in most languages the frequency scale expressed in amounts of time had to be simplified to establish equidis- tant responses. conclusions: a rigorous translation methodology was performed to ensure conceptual equiv- alence and acceptability of translations. international feedback obtained through the translation process re- vealed issues regarding the original instrument, indicating that future amendments to the original may be necessary. future psychometric testing will be conducted to ensure reliability and validity of each translation, appropriate- ness of the questionnaire in each country and compara- bility of data across countries. pmt assessing physician practice profitability using an activity based costing model stephens jm, bell cf, klingman d parexel international, outcomes research group, alexandria, va, usa physicians are increasingly challenged to maintain prac- tice profits in the face of tightening reimbursements from payers. while office visits generate a revenue stream for physicians, it is not clear whether frequent lower com- plexity visits (e.g., nurse visits to administer injections) are actually profitable for physician practices. objec- tive: to develop an adaptable model and methodology to evaluate profitability and financial incentives for vari- ous in-office services provided by physicians and their staff. methods: a literature and expert opinion based model was developed from the physician practice per- spective and was designed to be flexible for a variety of office-based services. the practice cost component of the model was developed using activity-based costing princi- ples and included direct (drug acquisition, supplies, clini- cal labor time, office visits) and indirect (malpractice in- surance, office rent) expenses. the practice revenue component of the model consisted of the reimbursement amount from payers, including: drug reimbursement; of- fice visits for physician evaluation, injections, end of treatment follow-up and adverse events; and laboratory tests. results: practice profitability is inversely pro- portional to the number of low complexity office visits per year. payer mix is also an important determinant of profitability for in-office services, with medicare reim- bursements generally resulting in a net loss for practices (� loss per office visit for the lowest complexity ser- vices) and typical managed care reimbursements provid- ing only small profits (approximately per low complex- ity visit). conclusions: frequent low-complexity office visits for administration of drug therapies do not appear profitable for physician practices under medicare reimbursement. alternative modes of drug delivery such as implantable drug delivery devices or patient self-ad- ministration may be more profitable for physician prac- tices by allowing substitution of more highly reimbursed office services. pmt valuing non-workplace productivity lost in migraineurs: human capital approach and replacement cost method kim ss, lofland jh office of health policy and clinical outcomes at thomas jefferson university hospital, philadelphia, pa, usa objective: to determine the non-workplace produc- tivity costs (nwpc) for migraineurs using the human capital approach (hca) and replacement cost method (rcm). method: this was a supplemental analysis to a prospective, observational migraine outcomes study conducted at a managed care organization. migraineurs self-reported their work status, occupational category, number of days missed from normal ‘activities’ outside of paid job(s) due to migraine symptoms, number of days performing normal ‘activities’ with migraine symptoms, and percent effectiveness while performing normal ‘activ- ities’ with migraine symptoms, at baseline, months, and months after the initiation of sumatriptan. daily occu- pational wages were obtained from the bureau of labor statistics. nwpc were calculated using the hca and php a systematic review of the european pharmaceutical market and the impact of european union regulation and jurisdiction a abstracts php a comparative analysis of the financing, pricing and reimbursement systems for prescription drugs in the nordic countries kristensen fko, sverre jm, holm lb pharmecon as, asker, norway objectives: to elicit similarities and differences in the poli- cies and practices for financing, pricing and reimbursing pre- scription drugs in the often perceived similar nordic countries of denmark (d), finland (f), norway (n) and sweden (s). methods: a review of the four countries’ authorities’ stated policies and practices on the matter were performed through a search of the literature and of the respective authorities’ home- pages. the information was validated through interviews with key personnel of the reimbursement agencies in each country, and the final study reports for the respective countries were reviewed by the same persons. results: all countries have a national health care system financed by taxation. there are dif- ferences in the reliance upon patient co-payment (n %, others – %) and whether financing is a county (s) or national (others) responsibility. all have regulated prices for reimbursed drugs; based either upon international comparisons (n, d) or country-specific decisions (s, f). the criteria used for deciding to reimburse a drug vary between the countries, and reimbursement is practiced differently in several other dimensions: mandatory requirement for pharmacoeconomic analysis (f, n, s), the existence of patient-specific reimbursement systems (d, f, n), product- (s) or indication-based (others) reimbursement, use of graded (f), conditional (n, s) or temporary (s) reimbursement, use of reimbursement contracts (n), and different processes for handling disagreement about decisions. conclusion: the nordic countries all have a national health care system financed by taxation and encompassing prescription drugs, but differ in a number of other dimensions with respect to financing, pricing and reimbursing such drugs. php a systematic review of the european pharmaceutical market and the impact of european union regulation and jurisdiction van ginneken ej, schreyögg j, gericke ca, busse r berlin university of technology, berlin, germany objectives: to examine the impact of the increasing role of the european union (eu) on the european pharmaceutical market, focusing on industry and national policies. to give a sys- tematic overview of the current state of the european pharma- ceutical market as a whole. methods: systematic literature review for the years – , including “grey” sources of information, online databases, european commission docu- ments and european court of justice rulings, relevant journals and systematically tracing back relevant references. results: the eu attempts to liberalise the pharmaceutical market and the realisation of a single european market (sem) came to a stand- still, after some considerable achievements (e.g. marketing authorisation). instead, the eu seems to concentrate on coor- dination of results through the adoption of the so-called g recommendations. eu member states successfully—and inten- tionally—kept control on the issues of pricing, reimbursement, pharmacies and prescribing. over the last years they adapted increasingly convergent measures to cope with rising pharma- ceutical expenditures, without long-lasting cost containment effects. however, recent european case law might prove to have far reaching consequences on the provision of medicines. the european pharmaceutical industry—although profitable—is underperforming compared to the usa, which is blamed on restrictive regulatory frameworks in the member states. con- clusions: the future of the actors in the european pharma- ceutical market is not clear. will it bring more european influence or a strengthening of national influence? in the short term, major change towards a sem seems unlikely, but in the longer term european history showed that major change is pos- sible. it seems clear that much depends on the attitude of member states towards the new approach and the interpretation and influence of european case law. for the european industry, adoption and implementation of g recommendations is of great importance for future competition with us-based companies. php using an italian population database to profile prevalence and costs of chronic conditions yuen ej, maio v, louis dz, rabinowitz c, robeson m, smith kd jefferson medical college, thomas jefferson university, philadelphia, pa, usa objective: individuals with chronic medical illness may have multiple health problems, and are often costly and difficult to manage. this study identifies those with highly prevalent chronic conditions and assesses related health service use and costs in the population of emilia romagna (rer), a large northern italian region. methods: pharmaceutical, hospital, and demographic data from and have been assembled for the entire population of rer ( million). pharmaceutical and hospital tariffs were a proxy for costs. pharmacy and hospital records were used to identify individual morbidity. data included demo- graphic and geographic information, encounter dates, diagno- sis/procedure codes, pharmaceutical information, and health care costs. individuals were classified as having a chronic condi- tion in , and we examined pharmacy and hospital use/costs in . descriptive analyses compared mean and total costs, as well as proportions within the population. results: we iden- tified five highly prevalent chronic conditions: cardiovascular dis- eases (n = , , . % of the population); rheumatologic conditions (n = , , . %); gastric acid disorders (n = , , . %); chronic respiratory illnesses (n = , , . %); and psychiatric disorders ( , , . %). . % of the population had one or more of these five chronic conditions, and these individuals accounted for . % of the pharmacy costs and . % of the hospital costs in the following year. for persons with these five conditions, we also described use and costs by age and gender, residence, and income. conclusions: interest- ingly, one-fourth of the population with selected chronic condi- tions accounted for large proportions of cost and use of health services. the ability to identify those with chronic conditions would help planners and governmental agencies to address health care needs, increase quality of care, avoid unnecessary hospitalizations, and save costs. these types of data can be used to estimate health care financing and risk adjustment models, and profile specific clinical, demographic or geographic sub-groups. php adherence index of performance—a new method and tool for ongoing evaluation of medication adherence improvement initiatives day d pfizer, new york, ny, usa objectives: to develop a

editorial comment mark w. pagnano md published online: november � the association of bone and joint surgeons the papers presented at the annual meetings of the knee society symposium includes selected manuscripts read at the members meeting of the knee society held in boston in october and the open scientific meeting of the knee society held in new orleans in march . the knee society education committee and program chair, richard iorio, md, assembled a broad array of scientific work for presentation at the meetings and this symposium issue includes the best of those presented. each paper has gone through a rigorous peer review and revision process for the authors but has resulted in a group of manuscripts that are of substantial value for readers. my sincere thanks go to the staff at corr for their timely and valuable hard work in assisting authors through the publication process. the insall award paper was authored by dr. douglas dennis and colleagues from denver who have delineated several risk factors for the development of symptomatic patellar crepitus after total knee arthroplasty. contemporary posterior-stabilized knee designs have lar- gely eliminated the problem of patellar clunk in which a fibrous nodule forms proximal to the patella and catches palpably and often audibly in the intercondylar box as the knee extends from a flexed position. however, patellar crepitus remains a clinical issue in a subset of patients and essentially represents a milder form of the same basic phenomena. after reviewing patients with patellar crepitus and matching them to patients without crepitus, the authors suggest several simple surgical strategies, including using larger patellar components whenever possible, maintaining patellar composite height after patellar replacement, and avoiding increases in posterior condylar offset. the ranawat award paper was authored by dr. thomas fehring and gathered data from colleagues around the united states regarding the fate of patients who fail an initial attempt at irrigation, débridement, and com- ponent retention for deep prosthetic infection around a total knee arthroplasty. much prior work has focused on the relative risks and on the rates of success/failure after irri- gation, débridement, and component retention. most contemporary authors would suggest that management strategy offers a % chance of success in controlling infection. little attention has been given to the subsequent efforts to control infection in those patients who fail an attempt at débridement and component retention. fehring and colleagues note that subgroup of patients is at much higher risk of treatment failure after two-stage fig. mark w. pagnano, md, is shown. m. w. pagnano (&) department of orthopedic surgery, mayo

the two-stage reimplantation as the first intervention for deep prosthetic infection. before abandoning débridement and component retention for at least a subgroup of patients, however, many surgeons will want to see further work to determine the effect of selection bias on the reported high reinfection rates for those for whom débridement has failed. the coventry award paper was authored by dr. hany bedair and colleagues and included collaboration between rush university and thomas jefferson university investigators. the authors introduce useful guidelines for the analysis of synovial fluid in ruling out infection in the early postoperative period (within weeks). prior work by numerous investigators provided data regarding synovial fluid analysis of late deep prosthetic infection and sug- gested synovial white blood cell counts of cells/ll or more indicated infection particularly when accompanied by a predominance of polymorphonuclear cells. in the early postoperative period, however, the present data show the cutoff value climbs substantially to , cells/ll. at that level the synovial fluid white blood cell count was % sensitive and % specific in detecting deep prosthetic infection. the remaining papers in this symposium cover a range of topics regarding the management of the arthritic knee, including unicompartmental knee arthroplasty, techniques in primary total knee arthroplasty, results of primary total knee arthroplasty, complications, and topics in revision tka. the high quality of these papers reaffirms the com- mitment of the knee society to advancing the international orthopaedic community’s collective understanding of sur- gery for the arthritic knee. we hope in this issue the typical reader finds useful information that can be incorporated into daily practice as well as some intellectual puzzles that spur further inquiry. pagnano clinical orthopaedics and related research papers presented at the annual meetings of the knee society: editorial

since its recent technical advances, mobile ultrasonography has become an extremely practical tool, allowing both diag- nosis and treatment of various musculoskeletal disorders. according to the authors, this book aims at being a “cookbook” for busy clinicians, including hand surgeons, orthopaedic surgeons, radiologists, and sports medicine spe- cialists. it is divided into five sections, subsequently entitled: introduction (dealing with basic ultrasound principles), fin- gers and wrist, forearm and elbow, shoulder, and masses. designed to allow clinicians to find information quickly and apply it to the intended clinical situation, the content includes bullet-point text, informative figures, and detailed clinical examples. each chapter is presented as follows: appropriate setup, anatomic landmarks, probe and patient positioning, normal anatomy, and relevant pathologic anat- omy. available injection techniques for anatomic areas and conditions are illustrated by pictures showing how to hold the probe and where to place the needle. in addition, selected chapters have video to demonstrate the techniques. the editors are: john r fowler jr, assistant professor, department of orthopaedic surgery, university of pittsburg medical center, pittsburg, pennsylvania, usa, and nandku- mar m rawool, associate professor, department of radio- logic sciences, thomas jefferson university, philadelphia, pennsylvania, usa. eleven american contributors have col- laborated in writing this work. richly illustrated and nicely written, this guidebook is also pleasantly and clearly presented. all the figures (pho- tographs, anatomical drawings, and ultrasound images) are demonstrative and of high quality. the bullet-points text makes it really easy to use. however, it must be kept in mind that it was the choice of the authors to deliver a “high-yield” format rather than dense paragraphs of information. as a result, the book may be of lesser interest for experienced clinicians. to sum up, this practical step-by-step guide may be greatly helpful for all physicians, seniors and residents, aim- ing to integrate musculoskeletal ultrasound in their clinical practice.

a sticky situation: the effect of the vitreomacular interface on neovascular amd treatment n eovascular age-related macular degeneration (amd) is the leading cause of vision loss and blindness in patients older than years in the united states. before the advent of anti-vegf agents, the natural history of neovascular amd was a rapid decline in vision with a resultant disciform scar and poor central vision. the phase marina and anchor trials showed not only that intravitreal administration of ranibizumab (lucentis, genentech) could maintain visual acuity in patients with wet amd, but also that treatment often led to improve- ment in vision, with a mean increase of to letters. , subsequently, the view and studies established the noninferiority of intravitreal aflibercept (eylea, regeneron) to ranibizumab in the treatment of neovascular amd. finally, the catt and ivan studies , established that bevacizumab (avastin, genentech) and ranibizumab had similar levels of efficacy when used as monthly intravitreal injections. protocols for neovascular amd treatment include monthly, as-needed (prn), and treat-and-extend (tae) reg- imens. tae is now the most commonly utilized treatment protocol for wet amd, with more than three-quarters of responders to the preferences and trends survey of the american society of retina specialists using this regi- men. several retrospective studies have demonstrated the efficacy of a tae protocol, and the prospective lucas trial has shown similar data at year. despite the excellent efficacy of anti-vegf agents in many patients with neovascular amd, some patients do not respond completely or continue to progress and lose vision over time despite maximal anti-vegf therapy. there is an ongoing effort to identify personal characteristics that may elucidate, influence, or predict one’s response to anti-vegf therapy. role of vma in an attempt to better understand these differences in response to anti-vegf therapy, the focus of current study has turned to an evaluation of the vitreomacular interface. higher rates of vitreomacular adhesion (vma) and lower rates of posterior vitreous detachment (pvd) are found in eyes with neovascular amd compared with either healthy eyes or those with dry amd. - what is not known is whether vma influences the development of wet amd or whether wet amd promotes vma. the excite trial included a subgroup analysis of patients in which the influence of the vitreomacular interface on wet amd treatment was investigated. based on findings from time-domain optical coherence tomog- raphy (td-oct), patients were divided into three groups: those with pvd, those with release of vitreomacular con- tact, and those with vma. the study found that in patients with a pvd, there was no significant difference in visual acuity in patients treated monthly or quarterly. conversely, in patients with release of vitreomacular contact or with vma, quarterly treatment resulted in significantly inferior visual acuity gains compared with monthly treatment. the study concluded that patients with vma might need more intensive treatment to achieve similar visual acuity results. we performed a study to determine the influence of /issue . new retina md young investigators the vitreomacular interface on treatment outcomes in patients with neovascular amd treated with anti-vegf agents using a tae protocol. this was a retrospective, consecutive case series of eyes of patients with new-onset neovascular amd. patients were divided into two groups based on spectral-domain optical coherence tomography findings: those with no vma (non-vma) and those with vma. mean age in the non-vma group was . and in the vma group . . in the non-vma group, mean pre-treatment visual acuity was / and mean central retinal thickness (crt) was . µm; in the vma group, the numbers were / and . µm, respectively. use of bevacizumab, ranibizumab, and aflibercept was similar between the groups. visual acuity in both groups improved significantly from baseline at years and . the non-vma group improved to / at year and / at year , while the vma group improved to / at year and stabilized at / at year . in each group, approximately % of patients gained or more lines of vision at years and . additionally, more than % of patients in each group avoided loss of or more lines of vision. crt decreased in conjunction with improving visual acuity. in the non-vma group, crt decreased to µm at year and µm at year . in the vma group, crt decreased to µm at year and µm at year . the vma group showed an increased percentage of persis- tent choroidal neovascular activity in comparison with figure . a -year-old man with neovascular amd in the left eye was treated with

interval extension was also significantly longer for the non-vma group ( . weeks at year and . weeks at years) compared with the vma group ( . and . , respectively). clinical utility the clinic utility of treating vma associated with neovas- cular amd was recently explored by novack and cowork- ers as they investigated the use of intravitreal ocriplasmin (jetrea, thrombogenics) in combination with anti-vegf agents. their randomized, prospective phase trial enrolled patients with vma and wet amd to compare combi- nation therapy (ocriplasmin plus anti-vegf) versus sham (anti-vegf alone). at year, safety profiles were similar to those of previous ocriplasmin trials, and the group treated with ocriplasmin had higher rates of vma release ( . % versus %) and total pvd ( % versus %) compared with the sham-treated group. of note, the combination group required % fewer injections ( . versus . ) com- pared with the sham group. with improved imaging technology, we are learning more about the vitreoretinal interface and its effect on numerous retinal diseases. there is much debate regarding whether vma is pathologic in nature or whether it repre- sents only a stage in the development of a pvd. additionally, there is the question whether vma is caus- ative or a bystander in the process. does vma with associ- ated tractional forces contribute to the development and pathophysiology of neovascular amd, or does the choroidal neovascularization result in a focal inflammation leading to abnormal adhesion of the posterior vitreous cortex to the internal limiting membrane and retina? there is evidence that traction from the vitreous may be proinflammatory and may even cause mechanical stress on retinal pigment epithelial cells and result in elevated vegf expression. the vitreous and vitreomacular interface may also act as a diffusion barrier. vitrectomy and pvd result in a more liquefied vitreous with decreased viscosity, leading to increased diffusion of oxygen, cytokines, growth factors, and medications. the vitreomacular interface, notably vma or vitreomacular traction, may act as a barrier to the diffusion of small anti-vegf molecules across the densely arranged collagen matrix of the posterior hyaloid and cortical vitreous into the retina. vma may also confine proangiogenic molecules in the retina by preventing their diffusion into the vitreous cavity. our current study suggests that anatomic factors may contribute to individual treatment responses and should be considered in treatment decisions for neovascular amd. although eyes with neovascular amd had similar visual acuity outcomes regardless of the configuration of the vitreomacular interface, eyes with vma may require more frequent and intensive anti-vegf treatment and have a decreased ability to extend the interval between injections (figures and ). n allen c. ho, md, is the director of retina research at wills eye hospital and a professor of

was statistically signifi cant (p . ). there was no signifi cant difference in haq scores between groups. conclusions: ra patients using current sc biolog- ics still suffer from serious impairments in symptoms, functional status, qol, and work/productivity. however, patients who discontinued sc biologic therapy have sig- nifi cantly worse symptom scores, physical functioning, and activity

france, nicox, sophia antipolis, france, european health economics, speracedes, france objectives: to estimate changes in quality of life (sf ) and utility (sf ) in patients treated with naproxcinod, naproxen or placebo for weeks, and to explore the effect of different disease measures on utility. methods: sf was available from international ph clinical trials in patients with knee or hip osteoarthritis comparing doses of naproxcinod ( and mg bid) to naproxen ( mg bid) and placebo. effi cacy was based on the pain, function and composite scales of the womac™ osteoarthritis index. co-morbidity measures included hypertension (ht) which increases with nsaid therapy, body mass index (bmi) and diabetes. changes in sf and individual sf domains were compared between the groups using anova and dunett’s -sided test. the effect of the womac™ indices, bp, bmi and diabetes on utility scores was explored using multiple regression analysis. results: all sf subscales except mental health as well as utility changed signifi cantly from baseline for all groups, and were correlated with changes in the womac™ indices (p . ). the change in the active groups was signifi cantly better than placebo for pain and physical function ( . ), but not signifi cantly different between treatments. however, absolute changes in utility, pain, physical function and general health were generally larger for naproxcinod mg than naproxen mg by around %. utility scores correlated signifi cantly with womac™, and patients with high bmi and bp or diabetes had lower utility scores and worse womac™ indices. increase in utilities were larger for patients with mg naproxcinod than for the other groups. conclusions: the slightly larger utility and quality of life changes with naprox- cinod mg despite a similar effect as naproxen on womac™ may be explained by a different side-effect profi le and a neutral blood pressure effect. pms an assessment of self reported outcomes in a nationally representative sample of elderly person diagnosed with rheumatoid arthritis rajpura jrjp j st. john’s university, fresh meadows, ny, usa objectives: to utilize webtv technology as a tool to measure hrqol in elderly persons having rheumatoid arthritis (ra) in a nationally representative sample and to describe their socio-demographic characteristics, medication use and other treat- ment choices. methods: a cross- sectional online survey research design. random digit dialing (rdd) survey procedures were used to draw a sample of elderly arthritic individuals from us households across states. a subsample of individu- als previously diagnosed with ra completed sf- v survey, as part of a larger study. eight sf- domain scores and physical and mental component summary (pcs and mcs) scores were computed and compared with cross-sectional norms for general us population. results: compared to the general population, our study sample per- formed poorly with respect to all the sf- domains except mental health (mh) and social functioning (sf) domains. ra is more prevalent in whites ( %) and males reported higher scores for all the eight sf- domains than females. about % of the sample reported the use of at least one available otc arthritic medication; % of the sample was taking prescription drugs, while about % reported having used natural/herbal remedies for arthritis. a signifi cant difference (p . ) was found between males and females with respect to only pcs scores. age was found to correlate negatively (p . ) with pcs and mcs summary measures, particularly for indi- viduals years and older. conclusions: webtv is an effective survey administra- tion tool for measuring hrqol. as expected, elderly perform poorly on three of the sf- domains (pf, rp, bp) having the most physical factor content. prescription drug use is fairly prevalent and use of otc medications and other forms of treatment is popular in the population under study. pms the effect of lifestyle choices on the risk of impairment in rheumatoid arthritis patients: an analysis of aerobic exercise and cigarette smoking shah a , plumb j , brawer r , tang b thomas jefferson university, philadelphia, pa, usa, centocor ortho biotech, inc, horsham, pa, usa objectives: through data analysis we will examine and identify the lifestyle factors that impact clinical outcomes of rheumatoid arthritis (ra) patients. methods: patients’ self-reported data was collected from the ra patient survey, an internet survey of ra patients. we studied the effects of aerobic exercise ( minutes a day per month), and cigarette smoking on ra patients. sign and symptom scores for morning stiffness, fatigue, and pain are defi ned from (no symptom) to (severe symptom) within the survey. the health assessment questionnaire (haq) was used to measure functional status scores ( – ). quality of life was measured by the mental component score (mcs) and physical component score (pcs) of the short-form (sf- ). productivity was measured by the work productivity and activity impairment (wpai) scale. there were no non-ra controls included in the study. results: a total of respondents were included in the analysis patients exercised and patients smoked cigarettes. the average age was . years and average ra duration was . years. patients’ mean mcs and pcs scores in the exercise ( . , . ) and non-smoking groups ( . , . ) were signifi cantly higher, than in the non- exercise ( . , . ) and smoking groups ( . , . ). overall work and productivity impairment was . % (exercise) versus . % (non-exercise), and . % (smoking) versus . % (non-smoking). signs, symptoms, and haq scores were signifi cantly better in the exercise and non-smoking groups (all p . ). conclusions: ra patients who exercise regularly have higher quality of life scores and clinical outcomes. those that smoke cigarettes have lower quality of life scores and higher symptom/ haq scores suggesting that this habit may be detrimental to their clinical outcomes. these results suggest that these lifestyle choices infl uence the overall risk of impairment in ra patients. pms is the health utilities index valid and

for health research, portland, or, usa, abbott laboratories, parsippany, nj, usa, united biosource corporation, bethesda, md, usa, leiden university medical center, leiden, netherlands objectives: qalys are an important outcome used in cost-effectiveness analysis. the health utilities index mark (hui- ) is a self-reported measure covering attri- butes of health status. our objective was to assess construct validity and responsiveness of hui- in ankylosing spondylitis (as). methods: data were derived from the adalimumab trial evaluating long-term effi cacy and safety in as (atlas). we speci- fi ed a priori hypotheses regarding the direction and magnitude of associations expected between overall and single-attribute hui- scores and other health status and quality of life measures—sf- , asqol, bath as functional index (basfi), bath as disease activity index (basdai), and patient’s global assessment (pga). using baseline data, we calculated correlation coeffi cients and interpreted them via guidelines suggested by guyatt for negligible, weak, moderate, and strong associations. responsiveness was assessed by calculating standardized response means (srms) of hui- scores from baseline to week for patients meeting the minimum clinically important differences (mcid) for the asqol ( . ). responsiveness analysis was limited to patients with -week hui- scores. results: a total of of the patients enrolled in atlas were included in the analysis. mean age was years, . % were male, and mean duration of as was years. correlation coeffi cients between hui- scores and other instruments confi rmed . % of the a priori hypothesis, with an additional . % being under- or over-estimated by only one category. results of responsiveness analysis demonstrated that there were signifi cant differences in overall hui- (srm . ) and most single-attribute change scores for patients whose changes were greater than the asqol mcid vs. those whose changes were mcid. conclusions: these results suggest that hui- constructs are related to similar constructs in other measures, as expected. this study provides evidence of cross-sectional and longitudinal construct validity of the hui- for deriving utility scores for as patients. pms validation of the multi-attribute health utility (mahu) derived from a computer adaptive instrument, cat- d-qol, in osteoarthritis

undergoing treatment for head and neck cancer at the thomas jefferson university hospital department of otolaryngology. participants completed surveys assessing readiness to quit smoking, amount of tobacco usage, and amount of time actively smoking. the easy way to stop smoking was provided to half of the participants, while the other half received a recommendation to purchase the book. all patients received physician directed smoking cessation counseling. phone surveys were conducted at short and long-term follow-up intervals to determine if the patients had purchased and/or read the book and whether they were still smoking. of the patients recruited, were eligible for follow-up, and only completed the long-term follow-up survey. the remaining participants were lost to follow-up for various reasons. those who received the book for free were more likely to read at least some of the book, p = . , although reading the book did not appear to correlate with successful smoking cessation, p = . . only % of patients who received the book (n = ) quit, while % of patients (n = ) who were recommended the book quit smoking, although this difference was not significant, p = . . patients who indicated “readiness” or “actively trying” to quit (n = ) appeared more likely to be successful than those who would only “consider” quitting (n = ), but the differences were not significant, p = . . smoking cessation rates did not appear to be impacted by reading allen carr’s the easy way to stop smoking. cessation rates between groups who read and did not read the book were similar, and the small differences were not statistically significant. despite a majority of the cohort indicating at least a readiness to quit smoking, only a small portion of patients managed to achieve successful smoking cessation. this study seems to support the notion that there is no single method to promote cessation, and that patient motivation remains an important factor in achieving long-term smoking abstinence. introduction: smoking is the most common preventable risk factor in the development of head and neck cancers[ ]. patients who smoke can be up to times more likely to develop cancers of the head and neck than non-smokers[ ]. oral cancer patients who continue to smoke are also at increased risk for developing additional primary malignancies[ ]. smoking cessation can reduce the risk of oral cancer by % within the first five years. after ten years, the risk of developing oral cancer approaches the risk of non-smokers[ ]. as such, it is extremely important to promote smoking cessation counseling in all patients who smoke, particularly those who have already been diagnosed with a head and neck malignancy. even after diagnosis, successful smoking cessation can improve survival rates. there are a variety of programs and interventions aimed at smoking cessation, although maintaining smoking abstinence is always a challenge. printed education materials have been found to improve physician practices, but their efficacy is as of yet inconclusive for patient outcomes[ ]. in the thomas jefferson university hospital department of otolaryngology, we believe one method that may be effective in convincing patients to quit smoking is the best-selling self-help book the easy way to stop smoking, by allen carr. this book explores the reasons people smoke, aiming to change smoker’s feelings about their addictions and challenge misconceptions in order to promote cessation. this study aimed to evaluate the efficacy of the educational, self-help book the easy way to stop smoking by allen carr in achieving smoking cessation in patients being screened or currently being treated for cancers of the head and neck. additionally, this study aimed to determine if providing the book for free improved the likelihood patients would read the book over recommending the purchase of the book. methods: study participants over the age of were recruited during office visits to the thomas jefferson university hospital – department of otolaryngology. current smokers who either underwent screening or were actively being treated for cancers of the head and neck were eligible for recruitment in this study. consenting participants were randomized into two treatment groups: intervention group: received physician counseling on smoking cessation with a recommendation to purchase the book the easy way to stop smoking by allen carr. control group: received physician smoking cessation counseling in addition to a free copy of the book the easy way to stop smoking books were provided by research nurses to allow for adequate blinding of the study physicians. recruited patients completed an “intake questionnaire” to determine, among other things, amount of cigarettes smoked per day, obstacles to quitting, family support, and readiness to quit smoking (evaluated on the following likert scale): = “not planning to quit” = “would consider [quitting] if a reasonable solution was provided” = “ready to take action” = “actively trying to quit” after the initial intake survey, patients were followed-up via phone at short (two weeks to six months) and long term intervals (six months to one year). timing of follow-ups depended on ability to reach the patients via phone. discussion: the easy way to quit smoking does not appear to be an effective intervention to promote smoking cessation by itself. reading the book did not appear to be associated with an increased likelihood to quit smoking. interestingly, those patients who did not read the book at all had the highest percentage of smoking cessation ( . %), as well as the highest mean cigarette reduction ( . %), although neither of these values were statistically significant, p = . and p = . , respectively. additionally, those patients who read the entire book (compared to those who read some or none of the book) showed the lowest average cigarette reduction ( . %), p = . . a cancerous diagnosis correlated with a minor increase in the likelihood that patients would quit smoking, although it was not a significant difference, p = . . these findings are inconsistent with the literature, as cancer has been shown to be an effective motivator for smoking cessation[ , ]. anecdotally, several patients surveyed admitted their cancer diagnosis was the major reason for their smoking cessation, and not the easy way to stop smoking. providing the intervention (i.e. allen carr’s book) free-of-charge ensured patients were more likely to utilize the intervention. those who received the book free of charge from the tjuh department of otolaryngology were more likely to read the book ( . %) than those who were only recommended to purchase the book ( %), p = . . when suggesting other smoking cessation interventions, cost to the patient may be a factor affecting compliance. identifying patients who are ready or motivated to quit smoking may be useful in targeting smoking cessation interventions, as these patients may be more likely to successfully quit smoking. finding the motivation to quit seems to be a major obstacle in smoking cessation, and is supported in the literature[ ]; those who are motivated to quit smoking are more likely to be successful. many of the study participants enjoyed reading the book, although few managed to successfully quit smoking during the study. patients who initially reported readiness to quit or were actively trying to quit smoking were successful in higher percentages ( . % and . %, respectively) than those who would only consider quitting ( %), p = . . despite a lack of statistical significance, these trends are certainly interesting. a similar study illustrated that patients with low motivation or low readiness to quit were unlikely to benefit from self-help materials, such as a smoking cessation book[ ]. the small sample size and large participant attrition are limitations of this study. while some attrition was expected, we did not anticipate losing the number of patients we did ( %). conducting the follow-up surveys via phone also presented challenges, as many of the study participants were either undergoing or recovering from treatment for head and neck cancers. likely, the stress and hardships associated with a cancer diagnosis contributed to some of the participant loss. another limitation was the study’s reliance on self-reported data collected in surveys. patients have been known to underestimate their cigarette intake[ ], and it’s entirely possible some patients may have overestimated the amount of the book they read. conclusion: nearly every patient surveyed that read the book enjoyed the the easy way to stop smoking, finding it both helpful and informative, although only a small percentage of patients managed to translate the book’s message into practice and achieve smoking cessation. due to the small sample size, it is difficult to make any concrete conclusions about the efficacy of allen carr’s the easy way to stop smoking, although the small percentage of patients who did quit smoking suggests there is no single “magic-bullet” approach that can tackle the intense nature of nicotine addiction. identifying a patient’s motivation to quit may be a useful tool in tailoring future cessation strategies and treatment, but achieving long-term smoking cessation still remains a major challenge to both patients and otolaryngologists. any attempts at promoting smoking abstinence should likely involve a multi- faceted approach. f( , ) = . , p = .

mcu. micu has been demonstrated to be a ca þ -sensing protein, which both sets a threshold for low ca þ concentration while it assures cooperative activation during high ca þ rises. mitochondrial ca þ uptake shows tissue specific differences and interestingly, mrna level for micus and mcus also displays tissue specificity. we set out to investigate if the stoichiometry between micu and mcu could account for the previously described differences between heart and liver in mitochondrial ca þ uptake. immunoblotting showed higher expression for all micu , micu and mcu in mouse liver versus heart mitochondria, and a . fold higher micu to mcu ratio in liver. in fluorometric measurements of mitochondrial ca þ uptake, heart mitochondria displayed a decreased threshold and lesser cooperativity compared to liver mitochondria. additionally, nad(p)h elevation was detect- able after exposure to moderate [ca þ ] elevations only in heart mitochondria. overexpression of micu in the heart using aav -micu tail-vein injection significantly increased the micu protein level without any changes of micu or mcu. this increased the micu to mcu ratio in the heart and led to increased thresholding and cooperativity, reproducing the liver-like mito- chondrialca þ uptakephenotype.viceversamicu downregulationintheliver has been shown to lower the threshold and cooperativity of mitochondrial ca þ uptake in hepatocytes. thus, heart and liver mitochondria show different levels of ca þ threshold and cooperative activation of ca þ uptake, which seem to result from differential quantitative relationship between micu and mcu. -pos board b er calcium release is tuned by mitochondrial redox nanodomains david m. booth , balázs enyedi , miklós geiszt , péter várnai , györgy hajnóczky . mitocare center, pathology, thomas jefferson university, philadelphia, pa, usa, department of physiology, semmelweis university, budapest, hungary. spatially and temporally controlled increases of h o emerge as an intracellular signal. we hypothesized that ros and ca þ interact locally, in the restricted vol- ume of the er-mitochondrial interface. these physically tethered structures host enrichments of ion transport proteins such as the ip receptor, which support elevated nanodomains of ca þ during signalling events and are sensitive to h o . we used the genetically encoded h o sensor hyper incorporated into an inducible linker system to probe the redox environment at the er- mitochondrial interface in hepg cells. we found a moderately elevated h o nanodomain which developes into a h o transient following ip receptor- mediated er ca þ release and mitochondrial ca þ uptake. pharmacological in- hibition showed that the transient was dependent upon er ca þ, mitochondrial membrane potential and functional electron transport chain. hyper measure- ments of the mitochondrial intermembrane space revealed significantly elevated h o within this volume. using electron microscopy we found that hepg mito- chondria possess a cohort of dilated cristae, which disappeared following ip - linked ca þ release. paxilline that inhibits mitochondrial bkca channels blocked the cristae reshaping and also abolished the h o transient at the inter- face. furthermore, paxilline caused suppression of the ip -linked calcium signal, whereas interface targeted killer red, a photoactivated h o source, induced sensitization to the ip -linked agonist. we conclude that the intermembrane/ cristae volume of mitochondria represents an oxidized pool fed by the electron transport chain. ca þ -uptake stimulates expansion of the mitochondrial matrix via kþ and concomitant water uptake, squeezing the oxidized volume of the cristae to the interface. here, a transient h o nanodomain sensitizes ip recep- tors to further stimulation. we demonstrate a physiological setting where ca þ release may autoregulate using mitochondrial h o released from the cristae. -pos board b reactive oxygen species (ros) suppress mitochondrial motility valentina debattisti, masao saotome, sudipto das, gyorgy hajnoczky. mitocare center, thomas jefferson university, philadelphia, pa, usa. mitochondrial distribution and transport play pivotal roles for many cellular functions, including cell differentiation, cell division to ensure proper inheri- tance, apoptosis, atp supply at the local sites of demand, ca þ buffering for intracellular ca þ homeostasis. we previously showed that mitochondrial motility (mito-motility) is regulated by the cytosolic ca þ concentration ([ca þ]c), providing the basis for a homeostatic circuit in which the organelles decrease their movements along microtubules to locally buffer high [ca þ ]c and contribute to atp supply. mito- chondria are also a major site for production and scavenging of ros that serve as both a messenger and regulator of calcium signaling and are particularly rele- vant for the control of mitochondrial function. here we tested the hypothesis that ros target mito-motility to control mitochondrial function. h c myoblast cells were transfected with a mitochondrial matrix targeted yfp and then loaded with fura , to monitor the mito-motility simultaneously with [ca þ ]c. h o ( mm) caused a decrease in mito-motility ( %) and an elevation in [ca þ ]c (from to nm) at the same time. when the cells were incu- bated in a ca þ -free medium and were pretreated with thapsigargin to prevent ca þ entry and intracellular ca þ mobilization, respectively, h o continued to inhibit the mito-motility dose-dependently without any changes in [ca þ]c. these results indicate that h o can cause suppression of mito-motility through a ca þ independent mechanism we are currently analyzing. -pos board b miro is dispensable for calcium-mediated inhibition of mitochondrial movement david b. weaver , agnieszka lewandowska , tammy t. nguyen , valentina debattisti , janet m. shaw , gyorgy hajnoczky . mitocare center, dept of pathology, anatomy and cell biology, thomas jefferson university, philadelphia, pa, usa, biochemistry, university of utah school of medicine, salt lake city, ut, usa. miro and are (rhot and ) are two highly similar gtpases that are bound to the surface of mitochondria and possess ef-hand calcium binding motifs. several groups have reported that miro is involved in mitochondrial motility and inheritance, and particularly its calcium regulation, but the roles of the two isoforms have not been established. genetic deletion of miro in mouse is lethal at birth (nguyen et al., ) and fibroblasts (mefs) derived from miro ko em- bryos show abnormal mitochondrial distribution, but the calcium-dependent in- hibition of motility is unaffected and the respiratory and calcium buffering capacities are normal. neuron-specific knockout of miro leads to progressive deficits of upper motor neuron function, however mitochondria in processes of cortical neurons from miro ko and wild-type embryos showed comparable calcium-sensitive motility inhibition. while no significant increase in miro pro- tein was observed in miro ko mefs, these data raise two possibilities: miro and are interchangeable with regard to calcium regulation of mitochondrial motility or miro is the key player in this regard. to finally resolve this question, we are in the process of generating miro ko and miro / ko cell lines. -pos board b mitochondrial fusion dynamics in the heart veronica eisner , ryan cupo , erhe gao , györgy csordás , lan cheng , jessica ibetti , j. kurt chuprun , walter j. koch ,

center for translational medicine, thomas jefferson university, philadelphia, pa, usa. heart physiology depends on oxidative metabolism that likely requires dy- namic and permanent reorganization of mitochondria by fusion and fission. to directly evaluate mitochondrial fusion dynamics in cardiomyocytes (cm), mitochondrial matrix-targeted photoactivatable gfp and dsred were intro- duced either in vitro or in vivo by adenovirus and were followed by confocal microscopy. four conditions were analyzed: to h cultured neonatal and in vitro transduced adult cm, and cm from in vivo infected rat hearts. in the latter case, cm were isolated - days after infection and were imaged promptly or - h post harvesting. neonatal cm mitochondria form a highly connected network, whereas both in vitro and in vivo transformed cultured cm displayed only some connectivity. impressively, in vivo transduced adult cm that were imaged promptly after harvesting, unveiled a significantly higher con- nectivity among mitochondria than the - h cultured adult cm. furthermore, fusion events (f.e./ square micrometers/min) were almost absent in cultured in vitro transduced cm, meanwhile in vivo transduced and cultured cm showed . . f.e./min, whereas isolated, freshly-imaged cm displayed . . f.e./min. imaging in perfused whole heart ex vivo, showed consider- able mitochondrial continuity and fusion activity in ventricular cm. to study more directly the role of cm’s contractile activity in mitochondrial fusion, cm were incubated with verapamil ( mm), that blocked spontaneous contrac- tion and partially suppressed the fusion activity of mitochondria. also, mito- chondrial fusion activity appeared to be higher after spontaneous contraction or short term field stimulation in isolated freshly-imaged cm. thus, mitochon- dria are dynamic in both neonatal and adult cm, but under culture conditions, adult cm lose mitochondrial fusion activity. this might be at least in part, because cardiomyocyte contractile activity is altered in culture and contractions likely provide some factors to support mitochondrial fusion activity. -pos board b mechanistic characterization of the thioredoxin system in the removal of hydrogen peroxide venkat r. pannala, ranjan k. dash. bioengineering and biotechnology, department of physiology, medical college of wisconsin, wauwatosa, wi, usa. the thioredoxin system plays a critical role in the defense against oxidative stress by removing harmful hydrogen peroxide (h o ). specifically, wednesday, february , a thioredoxin (trx) donates electrons to peroxiredoxin (prx) to remove h o and then thioredoxin reductase (trxr) maintains the reduced trx concentration with nadph as the cofactor. despite a great deal of kinetic information gath- ered on the removal of h o by the trx system from various sources/species, a mechanistic understanding of the associated enzymes is still not available. we address this issue by developing a thermodynamically-consistent mathematical model of the trx system which entails mechanistic details and provides quan- titative insights into the kinetics of the trxr and prx enzymes. consistent with experimental studies, the model analyses of the available data show that both enzymes operate by a ping-pong mechanism. the proposed mechanism for trxr, which incorporates substrate inhibition by nadph and intermediate protonation states, well describes the available data and accurately predicts the bell-shaped behavior of the effect of ph on the trxr activity. most impor- tantly, the model also predicts the inhibitory effects of the reaction products (nadpþ and trx(sh) ) on the trxr activity for which suitable experimental data are not available. the model analyses of the available data on the kinetics of prx from mammalian sources reveal that prx operates at very low h o con- centrations compared to their human parasite counterparts. furthermore, the model is able to predict the dynamic overoxidation of prx at high h o con- centrations, consistent with the available data. the integrated prx-trxr model simulations show that the coupling of trxr- and prx-dependent reduction of h o allowed ultrasensitive changes in the trx concentration in response to changes in the trxr concentration at high prx concentrations. -pos board b higher mitochondrial membrane potential induces ros production in the familiar form of frontotemporal dementia with mapt mutations noemi esteras gallego, selina wray, elisavet preza, andrey y. abramov. molecular neuroscience, institute of neurology, university college london, london, united kingdom. frontotemporal dementia and parkinsonism linked to chromosome (ftdp- ) is a neurodegenerative disorder caused by mutations in the mapt gene en- coding tau protein. mitochondrial alterations have been associated with neuronal death in several diseases. the objective of our study was to analyse the mitochondrial function in human ips cells from a patient of ftdp- car- rying the þ mapt mutation. in addition, we have selected three different time points of the differentiation from pluripotent stem cells to cortical neurons to study how mitochondrial alterations develop. we have used fluorescence imaging techniques to examine the mitochondrial function: tmrm to measure the mitochondrial membrane potential (dcm) and dyhidroethidium (dhe) to measure the rate of reactive oxygen species (ros) production. dcm was higher in ips-derived neurons from the patient bearing the mapt mu- tation ( . . % of control). higher dcm was also found in non- differentiated pluripotent stem cells ( . . %) and in the neural rosettes, which represent an earlier stage of the differentiation ( . . %). in contrast, mitochondrial mass was lower in mutant ips-derived neurons ( . . %), although it was similar in non-differentiated cells. we have also found that the rate of ros production, measured using dhe, was also higher in ips-derived neurons from the patient ( . % of control). the increased rate of ros production in these cells may be the consequence of the enhanced membrane potential. consistently, the rate of ros production in non-differentiated cells and in neural rosettes was also significantly higher ( . % and . %, respectively). our study indicates that this mapt mutation leads to a higher mitochondrial membrane potential, which induces a higher ros production that may be a trigger for neurodegeneration. -pos board b the overexpression of superoxide dismutase restores growth defect in a porin -less yeast

cytosol and mitochondria are made possible by the presence of the pore-forming protein vdac on the outer mitochondrial membrane [ - ]. vdac is directly involved in atp/adp, glucose and ions transportation, calcium homeostasis and apoptosis regulation. moreover, it shows high level of sequence conservation in all eukaryotes: the homologous por in yeast s. cerevisiae shows % of identity and similar functional prop- erties [ ]. recent studies have highlighted the existence of a link between vdac and sod enzyme, the most important cytosolic defense against superoxide anion. in yeast, sod is required to protect vdac from oxidation but also from carbonylation induced by ros [ ]; in addition, yeast strains devoid of endogenous sod show down-regulated vdac and tom levels, and vdac shows a significantly less pronounced voltage dependence and conductance [ ]. to unravel sod metabolic role in relation to vdac -mediated metabolism, we expressed human sod in yeast devoid of endogenous vdac (dpor ). while dpor strain cannot grow in the presence of a not-fermentable carbon source, possibly due to altered mitochondria, our results indicates that the overexpression of hsod in dpor strain relieves the growth defect, suggesting that sod participates in the mitochondrial metabolic intersection with the cytosol. acknowledgments: prin csjx f (vdp) and arisla (am).

creighton univeristy, omaha, ne, usa, biomedical sciences, creighton univeristy, omaha, ne, usa. aminoglycosides (ags) are the most widely used class of antibiotics in the world despite causing permanent hearing loss by damaging inner ear sensory cells. although the mechanisms of cochlear sensory cell damage are not fully known, reactive oxygen species (ros) are clearly involved. during normal mitochondrial metabolism low levels of ros, primarily superoxide, are pro- duced at complexes i and iii in the electron transport chain. these levels can increase when mitochondrial dysfunction occurs. complex i-specific ros for- mation was evaluated in acutely-cultured murine cochlear explants exposed to gentamicin (gm, mg/ml), a representative ototoxic ag antibiotic. mito- chondrial membrane potential and pro-apoptotic signaling were measured using tetramethylrhodamine and apoptosis-inducing factor (aif) labeling, respec- tively. fluorescence intensity-based measurements of nicotinamide adenine dinucleotide (nadh) were used to detect changes mitochondrial metabolism. relative amounts of superoxide and hydrogen peroxide produced during acute gm exposure were measured using mitosox red and dihydrorhodamine , respectively. gm increased nadh fluorescence intensity in low- and high-frequency sensory cells. the complex i inhibitor rotenone ( nm) significantly increased superoxide, not hydrogen peroxide, in low- and high- frequency sensory cells (p < . ). gm significantly increased superoxide and hydrogen peroxide formation in low- and high-frequency sensory cells (p < . ). rotenone increased gm-induced superoxide formation but decreased gm-induced hydrogen peroxide formation. this effect was greatest in high- frequency cells indicating fundamental differences in ros formation in high- and low-frequency sensory cells exposed to ototoxic antibiotics. this project provides a base for understanding the underlying mechanisms of mitochondrial ros production in cochlear cells during exposures to ototoxic antibiotics. supported by the national institute on deafness and other communication disorders (nidcd,ro dc ), and cobre ( p gm - ) to hjs and a ferlic

pennsylvania - ; department of general surgery, university of göttingen, göttingen, germany [a. m., h. b.]; and department of pathology, klinikum kassel, kassel, germany [j. r.] abstract hereditary nonpolyposis colorectal cancer (hnpcc) is an autosomal dominant genetic predisposition syndrome that accounts for – % of all colorectal cancers. diagnosis of hnpcc is based on family history (de- fined by amsterdam or bethesda criteria), which often includes a history of multiple synchronous or metachronous cancers. the majority of hnpcc results from germ-line mutations in the dna mismatch repair (mmr) genes hmsh and hmlh with rare alterations in hmsh and hpms in atypical families. both hnpcc and sporadic mmr-deficient tumors invariably display high microsatellite instability (msi-h). two types of hnpcc families can be distinguished: type i (lynch i) with tumors exclusively located in the colon; and type ii (lynch ii) with tumors found in the endometrium, stomach, ovary, and upper urinary tract in addition to the colon. a proposed association of breast cancer with type ii hnpcc is controversial. to address this important clinical question, we examined msi in a series of female patients who presented with synchronous or metachronous breast plus colorectal cancer. although msi-h was found in of ( . %) of the colon cancers, in all cases the matched breast cancer was microsatellite stable. we also examined the breast tumors from three women who were carriers of mmr gene mu- tations from hnpcc families. none of these three breast tumors dis- played msi nor was the expression of mmr proteins altered in these tumors. we conclude that breast cancer largely arises sporadically in hnpcc patients and is rarely associated with the hnpcc syndrome. introduction hnpcc is the most common human cancer predisposition syn- drome, accounting for approximately – % of the total colorectal cancer burden ( – ). hnpcc is clinically characterized by colorectal cancers, a proclivity to the proximal colon, and high frequency of metachronous and synchronous cancers ( ). the inclusion of extra- colonic cancers (endometrial, gastric, ovarian, and upper urinary tract) in addition to colorectal cancer, as well as a less stringent family history, distinguishes amsterdam criteria families from bethesda criteria families ( – ). the addition of breast cancer in bethesda criteria and/or type ii (lynch ii) hnpcc is controversial ( – ). alterations of the human mmr genes hmsh and hmlh account for the vast majority of hnpccs ( – ). mutations of other mmr genes are either absent (hmsh , hpms , and hmlh ) or rare and largely associated with atypical families (hmsh and hpms ; refs. and ). the detailed mechanism of tumorigenesis in hnpcc remains enigmatic ( , ), although it clearly begins with a “second hit” on the remaining mmr allele ( ). loss of mmr function results in elevated spontaneous mutation rates (mutator phenotype) that ac- celerate the adenoma-carcinoma transition associated with hnpcc tumors ( , ). the mutator phenotype associated with mmr defects is an example of induced genomic instability that leads to tumorigen- esis ( , , ). malignant transformation ensues when genes rele- vant for growth control and differentiation are affected as secondary mutation events. simple repeat sequences (microsatellites) are particularly prone to replication errors associated with the type of genomic instability that results from the loss of mmr function ( – ). tumor dna con- taining such replication errors can be distinguished by msi-h (when � % of the microsatellite markers are altered) or msi-l (when � % of the microsatellite markers are altered; ref. ). tumor tissues from � % of patients with an hnpcc syndrome (amster- dam or bethesda criteria) and % of patients with verified germ- line alterations of the hmsh or hmlh gene display msi-h ( , , ). mononucleotide repeat sequences appear to be the most unstable in bona fide hnpcc tumors ( ). these observations have led to the widespread use of microsatellite analysis as a diagnostic screening test for hnpccs ( ). in addition to hnpcc, msi-h is also found in – % of sporadic colorectal carcinomas ( , ). breast cancer affects one in nine women in the united states population ( , ). such a high incidence makes it is difficult to determine whether breast cancer is coincidental in hnpcc families or caused by the germ-line mutation in one of the mmr genes linked to hnpcc. the inclusion of breast cancer as an integral tumor in the hnpcc (lynch ii) spectrum rests largely on an analysis of breast and colon cancer tissues from a single female from a large hnpcc kindred ( ). the breast tumor from this individual displayed msi-h ( of or % of microsatellites analyzed) and a distinct pattern of msi-h in the colon tumor. moreover, loss of the wild-type mmr allele, in this case hmlh , was observed in the breast tumor tissue. supporting evidence for the inclusion of breast cancer in the type ii (lynch ii) syndrome comes from msi analysis of single breast tumors from five additional hnpcc kindreds. using the nci and the icg- hnpcc criteria ( , ), three of these breast tumors displayed msi-h. only one of these three breast tumors displayed instability at mono- nucleotide repeats. although these studies were performed prior to a clear definition of diagnostic msi ( , ), it appeared to provide compelling evidence for a correlation between breast cancer, hnpcc, and the litmus of mmr defects, msi-h. the frequency of msi in sporadic breast tumors is also controversial, with some reports sug- gesting the occurrence of msi in breast tumors ( , – ) and others suggesting a lack of msi in breast tumors ( , , ). recent interest in the relationship

spectrum has been intensified by the observations of scott et al. ( ). a survey of hnpcc families suggested a significant elevation in breast cancer susceptibility when hmsh - carrier families are compared with hmlh -carrier families. these observations would appear to have important implications for patient management and cancer surveillance, just as the exclusion of endo- metrial carcinoma as an integral hnpcc tumor resulted in a signif- icant delay in the diagnosis of hnpcc ( ). in a response to these studies, vasen et al. ( ) reported that a similar analysis of a hnpcc family cohort found that only of hmsh or hmlh mutation carriers had developed breast cancer. there was no differ- ence in the breast cancer risk for hmsh or hmlh carriers. both the scott et al. ( ) and vasen et al. ( ) studies cited the need for an analysis of colon and breast tumors from hnpcc individuals for clear signatures of mmr defects ( , ). synchronous or metachronous cancers are frequently associated with hnpcc and are among the criteria for identifying hnpcc patients and families ( ). here we have examined msi in patients identified with synchronous or metachronous breast plus colon cancer. we found that of ( %) of the colon tumors displayed msi-h. none of the corresponding breast tumors showed msi. in addition, independent breast cancer tissues from female members of three mmr mutation-positive hnpcc families were analyzed. although all of the colon tumors of those families displayed msi-h, all of the breast tumors were mss. taken together, these results suggest that breast cancer caused by mutation of the mmr genes is rare and should not be included in the hnpcc type ii (lynch ii) spectrum. materials and methods patients. this retrospective study is based on women with breast plus colon cancer who were treated at thomas jefferson university in philadelphia between and . a total of , female patients with colorectal cancer were seen as well as , with breast cancer. a total of women had both breast and colon cancer. paraffin blocks of both breast and colon tumors were acquired for of these patients. three additional women with breast cancer from confirmed mutation-positive hnpcc families where recruited from the german hnpcc registry. tumor blocks and blood were studied after obtain- ing informed consent. data on msi status of synchronous or metachronous extracolonic cancers (e.g., endometrial, stomach, ovarian, and upper urinary tract) were obtained from the thomas jefferson university familial cancer registry. of the patients analyzed with breast plus colon tumors, only was a member of the thomas jefferson university familial cancer registry. dna extraction. paraffin-embedded tumor and corresponding normal tis- sue sections were mounted on glass slides and stained with h&e. microdis- section was performed on paraffin sections stained briefly with methylene blue. areas of interest were selected by a surgical pathologist (t. b. e. and j. p. p.), scraped off the slide, and subjected to proteinase k digestion at a final concentration of mg/ml (qiagen, valencia, ca). dna was extracted with the qiaamp dna mini kit (qiagen), according to the manufacturer’s recommendations. for sequence analysis, dna from blood was extracted with qiaamp dna maxi blood kit (qiagen) following the manufacturer’s recommendations. microsatellite analysis. in accordance with the recommendations by the nci and the icg-hnpcc ( , ), six microsatellite loci were used to detect msi-h. three loci with mononucleotide runs (bat , bat , and bat ) and three loci with dinucleotide repeats (d s , d s , and d s ). these microsatellite loci had been recommended by dietmaier et al. ( ) as having the highest diagnostic sensitivity and specificity. primers were �-end labeled with hex, tam, or tet (perkin-elmer, foster city, ca). dna was ampli- fied in a standard reaction mix using amplitaq gold (perkin-elmer). the pcr products were run on an abi automated sequencer using fragment analysis software (genescan; perkin-elmer). additional peaks in tumor tissue dna, when compared with normal tissue dna, indicated msi. instability in � % of the markers was reported as msi-h, � % was classified as msi-l, and no instability was reported as mss. losses of heterozygosity were excluded as msi. immunostaining for hmsh and hmlh . to determine the presence or absence of mmr proteins, the breast tumors of the three members of the hnpcc families were subjected to immunohistochemical analysis. briefly, slides were deparaffinized and hydrated through graded alcohols. antigen retrieval was achieved by microwave treatment ( w for min) and incubation with % h o . nonspecific binding was blocked by incubation with goat serum for min. the slides were incubated with primary antibody against hmsh ( . �g/ml; oncogene sciences, cambridge, ma) or against hmlh ( �g/ml, clon g - ; pharmingen, san diego, ca) overnight at °c. the sections were then washed with pbs and incubated with the secondary biotinylated antibody. after rinsing with pbs, the sections were incubated with streptavidin-conjugated horseradish peroxidase (vector laboratories, burlingame, ca). for detection, the chromogen -amino- - ethylcarbazole (sigma chemical co., st. louis, mo) was used according to the manufacturer’s recommendations, and counterstaining was done with hematoxylin. mutation analysis. germ-line mutation analysis in the three hnpcc families was done by automated dna sequencing using big dye terminator chemistry (perkin-elmer) for sequence analysis on the applied biosystems model dna sequencing systems (pe applied biosystems, foster city, ca). pcr was performed on ng of genomic dna for each exon. the pcr products were purified using the qiaquick pcr purification kit (qiagen) and submitted for sequence analysis. the sequence was analyzed with the dnas- tar sequencher (gene codes cooperation, ann arbor, mi). results synchronous and metachronous cancers have been established by the icg-hnpcc as one of the criteria (bethesda criteria) for identi- fying hnpcc individuals and families ( ). for hnpcc type ii (lynch ii), synchronous and metachronous cancers include both colon as well as well-defined extracolonic tumors such as endometrial, ovarian, stomach, and upper urinary tract cancer ( ). to examine the role of breast cancer in type ii (lynch ii) hnpcc, we identified patients that presented with synchronous or meta- chronous colon plus breast tumors at thomas jefferson hospital. the tumor blocks for both the colon and breast tumor were acquired for of these patients, and microsatellite analysis of six different nci/icg- hnpcc recommended markers was performed on dna isolated from microdissected normal and tumor tissue regions (fig. ). the pathol- ogy and msi status of the breast and colon tumors from these patients are shown in table . msi-h was observed in colon tumors ( %; table ). none of the breast tumors examined displayed msi-h, which includes the corresponding breast tumors associated with the msi-h colon tumors (table ). consistent with previous observations, % of the msi-h colon tumors displayed instability in at least one of the mononucleotide microsatellites (bat , bat , or bat ). immunohistochemical analysis of a subset of the tumor tissue pairs confirmed the loss of expression of mmr proteins in the colon tumor tissue but not the breast tumor tissue (fig. ). we have previously characterized low microsatellite instability (msi-l; defined as instability in � % of examined microsatellite sequences). the genetic causes of the msi-l phenotype are unknown, although rare alterations of the hmsh mmr gene have been found within this cohort (data not shown; ref. ). approximately two- thirds of msi-l tumors display methylation inactivation of the mgmt promoter ( ). loss of mgmt exacerbates mutation rates by leaving unrepaired methylguanine damage in dna ( ). the majority of msi in mgmt-deficient tumors appears to be confined to dinu- cleotide repeats. these data suggest that the msi-l phenotype is unlikely to be significantly associated with mmr defects ( ). we found that of colon tumors ( %) and of breast tumors ( %) displayed msi-l (table and table ). in % of the msi-l tumors, instability was confined to the dinucleotide microsatellite markers. msi-l was found in two pairs of the synchronous and/or exclusion of breast cancer as tumor of hnpcc on april , . © american association for cancer research. cancerres.aacrjournals.org downloaded from http://cancerres.aacrjournals.org/ metachronous breast plus colon tumors. these data appear similar to sporadic colorectal tumors, which appear unrelated to hnpcc ( ). to further investigate the role of breast cancer in hnpcc, we identified three kindreds fulfilling the amsterdam criteria in which at least one female family member was diagnosed with breast cancer. molecular diagnostics of a proband in two families revealed deletion mutations within the hmsh gene (del c at codon ; del tc at codon ; fig. , a and b). a proband in the third family was found to contain an insertion in the hmlh gene (ins c at codon ; fig. c). all three of these mutations cosegregate with hnpcc and are pathogenic as a result of a premature truncation of the protein. moreover, the colon tumor tissues from affected family members of each of these kindreds display msi-h (data not shown). immunohis- tochemical analysis of the respective colon cancers suggested the loss of expression of hmsh in tumor tissues from family members that carried the hmsh deletion mutations and loss of expression of hmlh in the colon cancer from family members that carried the hmlh insertion mutation (see fig. for illustrative example; data not shown). a single female family member from each of these kindreds was confirmed to be a mutation carrier (data not shown), as well as presenting with breast cancer. we determined that all of the micro- satellite sequences analyzed using the dna isolated from breast tumors of these female family members were stable (mss). immu- nohistochemical staining revealed no loss of protein expression of either hmsh or hmlh in any of the breast cancers (see fig. for illustrative example; data not shown). in contrast, analysis of multiple colorectal or endometrial tumors from affected family members of all three families invariably displayed msi-h (data not shown). these data strongly suggest that the breast tumors of the mmr mutation- positive female family members arose independently of the hnpcc predisposition syndrome. discussion the lifetime risk of developing breast cancer in united states women is approximately % (one of nine). the lifetime risk of developing colon cancer in the general population is � % ( of ). the risk of colon cancer increases – -fold in persons who have a first-degree relative with colon cancer ( ). in the case of the devel- opment of two different cancer types, synchronous or metachronous, a hereditary predisposition must be suspected ( ). the recognition of hnpcc-associated cancers led to the bethesda criteria or the type ii (lynch ii) cancer predisposition syndrome. in , aarnio et al. ( ) performed a detailed pedigree analysis of hnpcc families to evaluate the cumulative risk of cancers other than colon cancer. at that time, endometrial cancer generated a cumulative risk high enough to suggest a specific surveillance program. these results underline the importance of identifying the correct hnpcc- associated tumors toward the recognition of affected families as well as appropriate clinical surveillance. endometrial, gastric, ovarian, and upper urinary tract tumors are generally accepted as integral tumors of the type ii (lynch ii) hnpcc syndrome. the inclusion of breast cancer in type ii (lynch ii) hnpcc is controversial ( , , – ). the use of well-defined microsatellite markers has established diagnostic msi as a valuable tool in the diagnosis of hnpcc ( , ). tumors from hnpcc patients that have been identified as carriers of pathogenic mmr mutations invariably display msi-h ( , , ). moreover, msi-h has been observed in % of the early adenomas from hnpcc mmr mutation carriers ( ). these studies have con- firmed the importance of msi-h as a fundamental indicator of mmr defects. table pathology and msi status of breast and colon tumors case no. breast cancer pathology msi status (breast) colon cancer pathology msi status (colon) inv. duct. caa mss muc adeno mss lcis msi-l carcinoid mss inv. duct. ca mss adenoca msi-l inv. duct. ca msi-l adenoca msi-l dcis msi-l muc adeno msi-l inv. duct. ca mss adenoca mss inv. duct. ca mss adenoca msi-l inv. lob. ca mss adenoca mss inv. duct. ca mss adenoca msi-h inv. duct. ca mss adenoca mss inv. duct. ca mss adenoca msi-h inv. duct. ca mss adenoca mss dcis mss adenoca msi-l inv. duct. ca mss adenoca mss dcis mss adenoca msi-h ln-metb msi-l adenoca mss inv. duct. ca mss adenoca mss inv. duct. ca mss adenoca mss inv. duct. ca mss adenoca mss inv. duct. ca mss adenoca mss lcis mss adenoca msi-h inv. duct. ca mss adenoca msi-l inv. duct. ca mss adenoca mss dcis mss adenoca mss inv. duct. ca mss adenoca mss inv. duct. ca mss muc adeno msi-h inv. duct. ca mss adenoca msi-l a inv. duct. ca, invasive ductal carcinoma;

ref. ). although of ( %) of the breast tumors could be classified as msi-l ( ), msi-h was not observed in any of the cases, and no differences were identified between patients with sporadic and hereditary breast cancer ( ). we remain perplexed by the original report of a molecular associ- ation between breast cancer and hnpcc ( ). it is important to note that the apparently confirmatory study by scott et al. ( ) contains no individual tumor molecular diagnostics and could therefore be easily attributed to chance association between familial susceptibility and sporadic tumors. although we were unable to identify any association between breast cancer, msi, and hnpcc, the results of risinger et al. ( ) would appear to suggest at least the rare occurrence of breast tumors associated with mmr defects. however, based on our studies, we propose that breast cancers should not be considered as an asso- ciated cancer when assessing hnpcc families. acknowledgments we gratefully acknowledge speculative discussions with henry lynch as well as comments and criticism by jeremy jass and kristine

anesthetics (va) are ion channels. the mechanism of volatile anesthetic action is not completely understood. identify- ing the molecular pathway for drug binding is crucial to understand the effect of va on voltage gated sodium channels. we use molecular dynamics simula- tions to identify the binding sites for a hydrophobic general anesthetic isoflur- ane, on voltage gated bacterial sodium channel nachbac. apart from the voltage sensing domain (s -s ), linker and the pore domain (s -s ), bacterial sodium channels also have fenestrations, which provide a hydrophobic tunnel through the lipid-embedded portion of the channel to the central cavity, where the known local anesthetic site is located. unbiased ‘‘flooding’’ simulations were performed on the activated open confirmation of nachbac. we per- formed a cluster analysis to identify all the possible binding sites of isoflurane. the three most important ones among them are: a region near the selectivity filter, called the extracellular site, a region near the s -s linker, called the linker site, and a region within the cavity, called the cavity site. the most important observation is that isoflurane enters the central cavity through the fenestrations. free energy perturbation method was employed to calculate the binding affinities of isoflurane for each of these sites. we also studied the interactions between isoflurane and the amino acids in these three binding sites. -pos board b a key gating charge interaction required for slow inactivation of the navab bacterial sodium channel tamer m. gamal el-din, todd scheuer, william a. catterall. university of washington, seattle, wa, usa. bacterial voltage-gated sodium (nav) channels are considered an ideal model for structure-function studies. the elucidation of the crystal structure of the bacterial channel navab (payandeh et al., nature , - , ) opened an avenue to understand electrical signaling in excitable cells at the structural level. navab expressed in hi insect cells as for structural studies has unusually negative voltage-dependent activation (va ~ mv). navab also has three phases of inactivation, a biphasic early inactivation process (t ~ ms, t ~ . s, at � mv) followed by an unusually strong and use-dependent slow-inactivation process. to search for the molecular basis for negative activation and slow inactivation of navab, we mutated the outer- most gating charge partner in the s segment, asn , to lys. this mutation shifted the activation curve ~ mv toward more positive potentials. surpris- ingly, it also completely abolished use-dependent slow inactivation. we showed previously that the equivalent residue in nachbac (asp ) interacts with the r gating charge in the s segment during activation using the disul- fide locking method (decaen et al, pnas ( ) - ). to test whether this interaction between r and n was critical for slow inactivation, we mutated navab r to cys. the resulting mutant navab_r c also had positively shifted channel activation (þ mv) and no use-dependent slow inactivation. the fact that these reciprocal mutations have the same functional effects suggests that interaction between r in the s segment and n in the s segment is an important link that stabilizes the activated state of the voltage sensor and triggers the slow inactivation process. -pos board b computational study of the prokaryotic sodium channel karen m. callahan, benoit roux. university of chicago, chicago, il, usa. ion-selective voltage-gated ion channels allow ions of a specific element or set of elements to pass, but exclude other ions. recently, the crystal structure of navab was published (payandeh et al ( ) nature , ), giving an un- ambiguous picture of the structure of the sodium channel selectivity filter (sf) of the prokaryote arcobacter butzleri. the filter is much wider than that of the narrow, carbonyl-lined potassium channels, allowing ions to penetrate with minimal dehydration, multiple pathways, and even to pass each other. previous computational studies have attempted to explain sodium selectivity, and claimed consensus (corry and thomas ( ) jacs , , furini and domene ( ) plos , e ). experimental ion selectivity determina- tion from pore-only constructs of a sodium channel with the same sf sequence shows stronger ion selectivity from reversal potential than from the ratio of the fluxes of sodium and potassium (shaya et al ( ) pnas , ), but selectivity, na þ/kþ, was still less than five. simulations based upon the closed-pore crystal structure could not determine selectivity directly from con- duction. to investigate this issue, we first calculated multi-ion potentials of mean force in the selectivity filter of pore-domain-only navab with an ex- tended equilibration period, and a replica-exchange molecular dynamics scheme, which allows for improved sampling. we then explored the non- equilibrium conduction of sodium and potassium in the presence of an applied electric field through a model navab pore truncated to mimic the conformation of the open pore. we also present multi-ion pmf calculations to illustrate similarities and differences between this model and the intact pore. when taken together, these two methods provide complementary views of ion selectivity and conduction based upon the conformation of the navab crystal structure of payandeh et al ( ). -pos board b volatile general anesthetic interactions with a bacterial sodium channel annika f. barber , srinivas g. raju , david lebard , vincenzo carnevale , michael l. klein , manuel covarrubias . thomas jefferson university, philadelphia, pa, usa, temple university, philadelphia, pa, usa. general anesthesia results from complex interactions involving ion channels in the brain. voltage-gated ion channels are modulated by halogenated inhaled general anesthetics, however the drug-channel interactions are generally believed to be non-specific making it difficult to investigate the molecular mechanisms of anesthetic action. we find, however, that the bacterial sodium channel nachbac exhibits differential regulation by different general anes- thetics, suggesting that there may be specific interactions. molecular dynamics (md) simulations have identified several possible binding sites for isoflurane in the nachbac channel structure. here, we have characterized the affinity, occu- pancy and hydrogen bonding for these sites and identified key interactions. in addition, experimental evidence suggests that both isoflurane and sevoflurane have dual actions on nachbac, possibly involving action at two different sites. consistent with pore block, sevoflurane accelerates the decay of the current ( % faster at . mm sevoflurane) but, at the same time, increases the peak current ( % increase with . mm sevoflurane), which argues against the blocking mechanism. we hypothesize that an additional mechanism involving a distinct site is necessary to explain the latter effect. we are currently employ- ing md simulation and structural modeling combined with mutagenesis and electrophysiology to test this two-site hypothesis and investigate the molecular mechanisms of these opposing effects. supported by ninds f ns (afb) and nigms p gm (mlk). -pos board b polymodal, high affinity actions of m-conotoxins on a bacterial voltage- gated sodium channel rocio k. finol-urdaneta , robert glavica , jeff r. mcarthur , robert j. french . university of calgary, calgary, ab, canada, rmit, melbourne, australia. m-conotoxins (mctxs) are potent blockers of eukaryotic sodium channels, and individual members of the mctx family are highly specific for particular nav isoforms. we have begun to explore mctx interactions with nachbac, a pro- karyotic nav channel closely related to navab, whose crystal structure was re- cently determined (payandeh et al, , nature : ). our data reveal actions on both ion conduction and gating, consistent with polymodal actions on the pore domain. under voltage clamp, whole-cell currents from nachbac expressed in tsa- cells were reduced, up to nearly complete block, by concentrations in the pm to mm range, for wildtype toxins and derivatives of mctx piiia and kiiia. for wildtype piiia, dose-response data ( . - , nm) yielded the following: ic = . nm; maximal fraction of current blocked = . ; hill coefficient = . . chen & chung ( , biophys. j. : ) predicted an ic of . nm for piiia when the navab channel is occupied by sodium ions. even at very low [piiia] ( pm), the unblocked currents showed increasing rates of inactivation as the peptides were washed in, suggesting a gating mod- ulation, that was not tightly associated with pore block. for mctx piiia ( . nm), or kiiia ( nm), inactivation accelerated by ~ -fold. substitution of key basic residues (piiia-r a and kiiia-k a) reduced blocking potency and decreased the speeding of inactivation to less than -fold. given the remarkably high selectivity and affinity that mctxs show for certain eukaryotic nav channels with highly asymmetric pores, it may seem surprising that they bind to symmetric bacterial nav channels with such high affinity. binding of isoflurane to a bacterial voltage-gated sodium channel: structure and accessibility of distinct interaction sites a key gating charge interaction required for slow inactivation of

of mitomycin c in the treatment of preexisting anterior glottic webs in patients undergoing microdirect laryngeal surgery over a six year period. methods: from through following treatment for recurrent respiratory papillomatosis or a persistent anterior glottic by either laser excision or microdebridement, twenty-five patients underwent topical application of mg/ml mitomycin – c to the anterior commisure. we retrospectively evaluated the efficacy of topical mitomycin – c in preventing web formation at the anterior glottis. results: nineteen manifested anterior webs during treatment, whereas six were successfully treated with mitomycin c without developing a web. % demonstrated resolution of the agw. conversely three patients developed new web formation following application of mitomycin c, all of which were subsequently cleared. only one patient was recalcitrant to therapy and required surgical lysis with keel placement. no patients developed laryngeal cancer during our study period. conclusion: topical application of mitomycin appears to effectively limit the recurrence or progression of anterior glottic webs in a significant portion of patients. topical mitomycin-c use in surgery of the anterior commisure ryan c murray, md; jeanine speilberger, md; maurits boon, md; joseph r spiegel, md thomas jefferson university hospital, philadelphia, pa a total of twenty five patients were identified including eighteen male and nine female patients. six patients were successfully treated with mitomycin following instrumentation at the anterior commisure and never manifested anterior webbing. the remaining nineteen patients were observed to have an anterior glottic web at some point during therapy (table ). of these patients were initially taken to the or for surgical treatment of an agw. mmc resulted in resolution of agw scarring in of those patients, of which after only a single administration. patients were subjectively evaluated for the extent of web involvement over the course of treatment. the majority of patients experienced resolution of the agw following mmc application (fig ). an anterior web in one patient increased in size despite therapy with mitomycin and required subsequent open surgery with endolaryngeal keel placement. three patients developed new webs during treatment all of which resolved with subsequent therapy. only two patients had evidence of agw at the time of last clinical evaluation, whereas twenty three patients did not demonstrate webbing at their last evaluation. one patient had juvenile rrp but was an adult at the time of agw formation. one patient who had previously undergone a renal transplant and was on well controlled long term immunosuppression was included in the study. two patients had previously been treated for t laryngeal squamous cell carcinoma by primary radiation therapy. one patient with congenital glottic webbing treated with mmc was excluded from analysis, however did experience resolution of disease following a single treatment. no patients developed significant dysplasia or laryngeal cancer during the study period. following initial enthusiasm for the use of mmc in the anterior glottis has had limited but encouraging results (roh, ; spector, ). animal models appear to indicate mmc is a useful tool to prevent scarring when operating at this area. however traditional surgical lysis of anterior glottic lesions persist. previous studies using surgical lysis followed by keel insertion report recurrence of agw between and % (edwards, ; lichtenberger, ) in our cohort more than % of the patients treated with mmc demonstrated objective and sustained resolution of the agw. six patients underwent surgery at the anterior commisure without subsequent development of agw, whereas three developed new webbing after mmc application. all of these patients were able to be treated more aggressively than if mmc was not used. mmc primarily acts to inhibit dna translation thus exerting an effect to decrease proliferation of fibroblasts. additionally it has been shown to induce fibroblast apoptosis and limit angiogenesis. topical application appears to be safe for use in the head and neck with little or no systemic side effects (veen, ). in our cohort there were no incidences of malignant degeneration, or worsening dysplasia. previous reports examining mmc in patients developing webs following scca confirms our results (knott, ). we recognize inherent limitations to this study. firstly the retrospective nature of the review limited more sensitive assessment of web size. many of the patients also received concurrent or metachronous cidofovir injections, the impact of which is unclear. this study was approved by the thomas jefferson university hospital irb study number d. . a retrospective chart review was conducted to evaluate all patients over the age of undergoing endoscopic surgery at the anterior commisure between january , and december , . all procedures were performed at the lead investigators institution. all patients subjected to instrumentation at the anterior commisure with subsequent application of mitomycin c were included in the study. instrumentation was most frequently cold steel, but could include microdebridement or laser excision. patients with a history of adult or juvenile onset recurrent respiratory papillomatosis as well as those with previously known anterior glottic webs were included. patients previously or concurrently undergoing treatment with cidofovir were also included. all patients with a known history of connective tissue disease, wegner’s disease and sarcoidosis were excluded. application of mitomycin c was performed subsequent to all other endoscopic instrumentation and immediately preceding the end of surgery (fig ). from until late patients were treated with a topical preparation of mg mitomycin/ml. this was applied to the anterior commisure for minutes then removed for minute and reapplied for an additional minutes. from late until the conclusion of the study period mitomycin at a concentration of mg/ml was applied topically for a continuous minute period. charts were reviewed for presence of and size of anterior glottic webbing and mmc application to the anterior commisure. patients were noted to have resolved, improved, stable, worsened or new web formation, based on clinical or operative exam. - mmc is effective in treating anterior glottic webs in more than % of patients - more than half of patients that demonstrated a resolution of agw following mmc did so after a single treatment - mmc allows for more aggressive surgery at the anterior commisure - mmc results in less morbidity and faster recovery than traditional keel prostheses endolaryngeal surgery for benign lesions at the anterior commisure is performed cautiously due to the risk of acquired glottic webs (agw). agw presents a difficult management dilemma due to the risks of airway compromise and impacts on voice (mcguirt, ). conventional therapies of agw have included intralesional kenalog injection, keel insertion, division followed by repeated dilation and mucosal grafting (hsiao ty, ). in recent years a shift in management toward endoscopic laser lysis of laryngeal stenosis has resulted in significant improvements in voice outcomes (knott, ), but has relied on the use of keel or sialastic stent placement to prevent the risk of glottic webbing (monnier, ). while these adjuvant therapies have demonstrated acceptable outcomes they typically require tracheotomy placement and carry a risk of granulation formation requiring additional surgery (edwards, ). mitomycin c (mmc) is now routinely employed for prevention of scar formation in tracheal stenosis as well as subglottic and posterior laryngeal stenosis (perepelitsyn, ). limited animal models as well as in vivo human studies addressing its use for anterior glottic stenosis indicate it may prove to be a useful adjunct in the treatment of agw. introduction methods and materials . edwards, j., tanna, n., bielamowicz, s.a. endoscopic lysis of anterior glottic webs and silicone keel placement. annals of otology,

switched from clopidogrel to a gen apt, there was not an increased risk of stent thrombosis. this data suggests that gen apt may be employed in higher risk patients but do not increase the risk of stent thrombosis, implying adequate compli- ance in these high-risk patients. atherectomy devices crt- comparing the procedural and -day outcomes in patients with or without a history of coronary artery bypass graft when treating de novo, severely calcified coronary lesions with orbital atherectomy: results from orbit ii jeffrey w. chambers, michael s. lee, arthur c. lee metropolitan heart and vascular institute, coon rapids, mn; ucla medical center, los angeles, ca; the cardiac and vascular institute, gainesville, fl background: in prior studies, patients with previous coronary artery bypass grafting (cabg) experienced significantly greater incidence of adverse clinical events upon subsequent repeat cabg, percutaneous coronary intervention, or medical treatment, compared to patients with no prior cabg. in this analysis, we evaluate the procedural and -day outcomes in patients with and without a history of previous cabg in the orbit ii trial. methods: the orbit ii trial, a prospective, multicenter, non-blinded clinical trial that enrolled consecutive patients, was designed to evaluate the safety and efficacy of the coronary orbital atherectomy system to prepare de novo, severely calcified coronary lesions for stent placement. procedural and -day outcomes in patients with history of previous cabg (n¼ ) and no history of cabg (n¼ ) were evaluated in this analysis. results: compared to patients without history of previous cabg, patients with history of cabg were more likely to be male (p¼ . ) and have a higher prevalence of diabetes mellitus (p¼ . ), history of dyslipidemia (p¼ . ), hypertension (p¼ . ), and myocardial infarction (mi) (p< . ). the rate of procedural success (stent delivery with residual stenosis < % without the occurrence of an in-hospital major adverse cardiac event (mace)) was similar . % (previous cabg) and . % (without previous cabg) (p¼ . ). statistically similar low rates of severe dissection ( . % vs. . %: p¼ . ), perforation ( % vs. . %: p¼ . ), persistent slow flow ( % vs. . %: p¼ . ), and abrupt closure ( . % vs. . %: p¼ . ) were observed in the history of cabg and no history of cabg groups, respectively. as estimated by kaplan meier at -days, patients had similar low rates of mace (previous cabg: . % vs. without previous cabg: . %, p¼ . ). conclusion: preparation of severely calcified coronary lesions with the coronary orbital atherectomy system facilitated stent delivery in patients with a history of previous cabg, resulting in low rates of -day mace. crt- outcomes in chronic kidney disease patients treated for coronary arterial disease utilizing the orbital atherectomy system: an orbit ii sub-analysis arthur c. lee, stevan i. himmelstein, jeffrey w. chambers the cardiac and vascular institute, gainesville, fl; the stern cardiovascular center, memphis, tn; metropolitan heart and vascular institute, mercy hospital, coon rapids, mn background: cardiovascular disease is common in patients with chronic kidney disease (ckd) and often results in severely calcified lesions that are difficult to cross and treat. as a result, this population may have worse clinical outcomes following percutaneous coronary intervention compared to patients without ckd. clinical trials typically exclude this patient population. methods: orbit ii patients with severely calcified coronary lesions treated with the coronary orbital atherectomy system (oas) were divided into three groups based on the estimated glomerular filtration rate (egfr, ml/min/ . m ) at baseline: i (ckd stages - ), egfr< (n¼ ); ii (ckd stages - ), egfr to < (n¼ ); and iii (normal), egfr� (n¼ ). results: patients in groups i and ii were older (p< . ), and there were more females in these two groups than in group iii (p¼ . ). history of previous stroke (p¼ . ) was more prevalent in groups i and ii. in addition, the total length of calcium was significantly longer in group ii (p¼ . ). similar successful stent de- livery occurred in . %, . % and . % (p¼ . ) of cases with < % residual stenosis in . %, . % and . % (p¼ . ) of subjects in groups i, ii and iii, respectively. statistically similar low rates of severe dissection ( . %, . %, . %: p¼ . ), perforation ( . %, . %, . %: p¼ . ), persistent slow flow ( . %, . %, . %: p¼ . ), and abrupt closure ( . %, . %, . %: p¼ . ) were observed in groups i, ii, and iii, respectively. the day freedom from mace rates in groups i ( . %), ii ( . %), and iii ( . %) were similar (p¼ . ). conclusion: severely calcified coronary lesion pre-treatment with the coronary oas resulted in similar day freedom from mace rates and low rates of procedural complications in ckd patients compared with the non-ckd patients despite the older demographic and longer length of calcium in the ckd patients. crt- gender difference on procedural and -day outcomes in patients treated with orbital atherectomy for de-novo, severely calcified coronary lesions: results from the orbit ii trial christopher kim, jeffrey w. chambers utah cardiology, pc, layton, ut; metropolitan heart and vascular institute, mercy hospital, coon rapids, mn background: previous studies have shown a negative correlation between female gender and adverse events after percutaneous coronary intervention (pci). in this analysis, we evaluate the procedural and -day outcomes of male and female patients in the orbit ii trial. methods: the orbit ii trial, a prospective, multicenter, non-blinded clinical trial that enrolled consecutive patients, was designed to evaluate the safety and efficacy of the coronary orbital atherectomy system to prepare de novo, severely calcified coronary lesions for stent placement. procedural and -day outcomes in male patients (n¼ ) were compared to female patients (n¼ ). the primary safety endpoint was freedom from major adverse cardiac events (mace) at days post-procedure. the primary efficacy endpoint was procedural success defined as stent

the use of the tryton™ dedicated bifurcation stent via the transradial route - a single centre experience ashish shah, muezz uddin, shantu bundhoo, richard anderson, tim kinnaird university hospital of wales, cardiff, cardiff, united kingdom background: the use of the transradial access (tr) for the treatment of coronary bifurcation lesions (cbl) with percutaneous coronary intervention (pci) can be limited where a two stent strategy is required as larger sheath and guide catheters are required to facilitate stent delivery. with the development of newer dedicated bifur- cation stents, there is an increasing trend of these stents to be adopted in pci centres to treat cbl’s. we report our experience of the use of the tryton� dedicated side branch bifurcation stent at our default tr centre where % of all pci are carried out via the tr. methods: this was a prospective study of all patients who were found suitable to undergo pci to cbl’s using the tryton stent between september and june . data on patient demographics and procedure characteristics was collected from the local hospital database. results: patients (male . %, age . years) underwent pci using the mm long tryton� bifurcation stent. most of the cbl’s treated were located in the lad/branch ( . %), followed by the circumflex/branch ( . %), left main stem/branch ( . %), rca/branch ( . %) and lima graft ( . %). tryton� stents dimensions (side branch/main branch diameters) deployed were ( . / . mm - . %; . / . mm - %; . / . mm - . %; . / . mm - . % and . / . mm - . %). . % of cases were carried out via f guide catheters with the remaining cases carried out via the f. mean contrast volume, radiation dose and fluoroscopy times were mls, . gy/cm and . minutes respectively. . % of all cases were successfully carried out via the tr route with remaining cases switching to the transfemoral route to successfully complete the procedure. conclusions: when treating cbl’s, a wide range of tryton� dedicated side branch stents can be safely and effectively deployed via the tr route using f/ f guide catheter systems. this can avoid the use of the transfemoral route and its associated potential vascular complications. cabg crt- under-utilization of statins and aspirin following coronary artery bypass graft surgery kevin curl, bryan lebude, nicholas ruggiero, david fischman, andrew rose, sulay patel, david ogilby, paul walinsky, babu jasti, michael savage thomas jefferson university hospital, philadelphia, pa background: coronary artery bypass graft (cabg) surgery is commonly performed to treat ischemic heart disease, but long term benefits are limited by patency of saphenous vein grafts. both statin medications and aspirin hold class i indications for all post-cabg patients and should be continued indefinitely unless contraindication exists. unfortunately, there is limited data regarding long-term usage of these medi- cations. we assessed utilization rates among post-cabg patients without docu- mented contraindication. methods: a retrospective analysis of post-cabg patients presenting to the thomas jefferson university cardiac catheterization laboratory for a catheterization procedure at least years after surgery was performed. inpatient and outpatient records were reviewed to assess prescribing patterns of these medications, as well as other pertinent clinical and laboratory data. results: the study population consisted of consecutive patients who presented on average � years from the time of cabg. mean age of our study population was � years with % male. the most common indications for catheterization were unstable angina ( %), non-stemi ( %), and an abnormal stress test ( %). only % of patients were being prescribed a statin, while % were prescribed aspirin. only % were prescribed both at the time of catheterization. three percent had a documented intolerance to statin therapy. patients prescribed a statin had a significantly lower mean ldl ( vs. [p< . ]) and total cholesterol values ( vs. [p< . ]). thirty five percent of patients had ldl � . only % of saphenous vein grafts among the patients not on statin medications remained patent an average of years post-cabg surgery. conclusions: long-term statin and aspirin use following cabg surgery remains suboptimal despite clear guideline recommendations and clinical trial evidence of their effectiveness. coordinated efforts are needed to improve long-term medication usage in this subset of high risk patients. cardiovascular pharmacology crt- omeprazole use is associated with increased cardiovascular

multivalent adnectin binding to receptor clusters. as controls for the functional activity of the adnectin-a and the affinity of the monovalent interaction, the same kinexa assay was used, substituting the soluble receptor x extracellular domain for the transfected cho cells. the binding avidity measured by kinexa for cho expressed receptor is pm for both species of receptor x. however, the affinity of adnectin-a for monovalent soluble receptor x was quite different between the species suggesting that avidity due to receptor clustering equilizes the functional avidity at the cell

kchip a yi-quan tang , fan yang , jingheng zhou , jie zheng , kewei wang . peking university, beijing, china, university of california at davis, davis, ca, usa. a-type kv potassium channels undergo a conformational change towards a non-conductive state at negative membrane potentials, a dynamic process known as closed-state inactivation (csi). csi causes inhibition of channel ac- tivity without prerequisite of channel opening, thus providing a dynamic regu- lation of neuronal excitability, dendritic signal integration and synaptic plasticity. however, the structural determinants underlying kv csi remain largely unknown. we have recently demonstrated that auxiliary kchip a sub- unit contains an n-terminal kv inhibitory domain (kid) that directly interacts with kv . channels to enhance csi. in this study, we utilized the fret two- hybrid mapping and bifc-based screening combined with electrophysiology, and identified the intracellular tetramerization (t ) domain that functions to suppress csi and serves as a receptor for the binding of kid. disrupting kv . t -t interaction by mutating c a within the c h motif of t domain facilitated csi, and ablated the kid-mediated enhancement of csi. furthermore, replacing the characteristic c h motif of kv . t domain with the t domain from kv . without the c h motif or kv . with the c h motif resulted in channels functioning with enhanced or suppressed csi, respectively. taken together, our findings reveal a novel role of the t domain in suppressing kv csi with the c h motif functioning to stabilize the channel activation gate; and kchip a kid directly interacts with the t domain to relieve the stabilization, leading to facilitation of csi and inhibition of channel function. -plat two-in-one: activation and inactivation at the intracellular gate of a kv channel manuel covarrubias , jeffrey d. fineberg . neuroscience, jefferson medical college of thomas jefferson university, philadelphia, pa, usa, physiology and molecular biophysics, jefferson medical college of thomas jefferson university, philadelphia, pa, usa. n-type and p/c-type inactivation are firmly established mechanisms of inac- tivation in voltage-gated kþ (kv channels). however, kv .x channel com- plexes, which undergo fast preferential closed-state inactivation (csi; fineberg et al., , jgp . : - ), appear to use a distinct but un- known inactivation mechanism. previously, we hypothesized that a weak interaction between the voltage sensing domain and the intracellular activa- tion gate underlies csi (bähring & covarrubias, , j physiol : - ). thus, csi is essentially governed by the intracellular activation gate, which fails to open and adopts an inactivated conformation. to directly test this hypothesis, we investigated the heterologously expressed kv . ternary channel complex including accessory subunits kchip and dpp , and ex- ploited the ‘‘trap-door’’ paradigm of the activation gate. the results show that kv . inactivation traps intracellularly applied quaternary ammonium blockers (btbua and tbua) inside the channel’s pore. the trapped blockers can only escape if the channels are opened again by subsequent depolariza- tions. by contrast, inactivation cannot trap tea, whose binding kinetics is faster than that of channel gating. moreover, under identical conditions, a shaker kv channel (shb-t k) known to exhibit fast p/c-type inactivation cannot trap btbua. these findings conclusively suggest that the intracellular activation gate of the kv . ternary channel complex plays a novel dual role, controlling both activation and inactivation. supported in part by nih grant r ns (mc). -plat development and validation studies of universal pharmacophore models for herg channel openers serdar

informatics, university of calgary, calgary, ab, canada. the intra-cavitary drug blockade of herg channel, a common off-target for many drugs, have been extensively studied both experimentally and theoreti- cally. structurally diverse ligands inadvertent blockade of rapid component of delayed rectifying kþ currents are potentially pro-arrhythmic and may lead to drug-induced long qt syndrome-lqts. there are a number of natural strategies for rational drug design; one dubbed the ‘‘passive’’ approach avoids block of herg whereas the ‘‘proactive’’ strategy designs treatments to acti- vate the channel. while ‘‘passive’’ approach has been developed for decades, studies of structural mechanisms of herg channel activation by small mole- cules are truly novel. accordingly, design of the herg openers or current ac- tivators may offer a momentum for modern anti-arrhythmia drug development. significant number of small molecules with capacity for herg activation was identified in mandatory herg screens. to establish possible correlation be- tween activators structure and reactivity, we attempted to construct a universal pharmacophore model for herg channel openers using phase protocol. the biochemical data on kþ channel activators are used in training and test sets. these compounds span a wide range of structurally different chemotypes with ~ ^ -fold variances in binding affinity, which is sufficient for statistically sound model. a developed five sites aahhr (a, hydrogen-bond accepting, h, hydrophobic, r, aromatic) pharmacophore model has showed reasonable high statistical results compared to other constructed models and was selected for steric and electrostatic contour maps analysis. the predictive power of the model was also tested with external test-set (as true unknowns) compounds. pharmacophore model is also combined with previously developed receptor- based homology model of herg k channel and novel activators are generated and screened. the developed ligand-based models may serve as a basis for the synthesis of novel potential therapeutic herg activators. -plat n-terminal regulation of herg kd channel deactivation steven j. thomson,

channels maintains ikr dur- ing final repolarization of the cardiac action potential and opposes asynchro- nous early depolarization. inherited point mutations in herg that accelerate deactivation of ikr cause long qt syndrome (lqts), a disorder of ventricular repolarization that increases the risk of lethal cardiac arrhythmia. the intracellular n-terminal domain of herg is known to be essential for slow deactivation. deletion of the entire (~ residues) or just the initial residues of the n-terminus accelerates deactivation -fold. the same effect is achieved by neutralization of the charged residues, arg or arg . how many of the n-termini are required to slow channel deactivation is unknown. herg , like other kv channels, is a homotetramer. by repeatedly linking the c-terminal of one subunit to the n-terminal of the next subunit we constructed concatenated herg tetramers. a variety of homomeric and heteromeric concatenated tetramers were characterized (i.e., wtn/r a:r a( -n); where n = to ). the concatenated channel containing a single r a/r a subunit and wild-type subunits deactivated as fast as the concatenated channel con- taining only r a/r a subunits. the lqts-associated mutation r q, located in the n-terminal of herg was also studied. again, a concatenated tetramer containing a single mutant subunit deactivated as fast as channels with r q mutations in all four subunits. our results show that all n-termini are required to mediate slow deactivation in wild-type herg channels. -plat lipid affinity to the voltage-gated potassium channel kvap elise

was given intravenous recombinant tissue plasminogen ac- tivator, despite the normal ct pulmonary angiogram. later, upper and lower extremity venous doppler ultra- sound were negative for femoropopliteal thrombosis. the pelvic veins were not imaged by a venogram, and could well have been the source of pulmonary embolism. he was started on intravenous heparin, and contrast echocardio-

established that rv dysfunction in pulmonary embolism is central to the patient’s outcome acutely. pressure overload from pulmonary embolism, re- sultant myocardial ischemia, poor left-ventricular filling and diminished cardiac output ultimately lead to cardio- genic shock, which, if not reversed promptly, results in death. making a decision to aggressively treat acute pul- monary embolism becomes simpler if there is radiologic evidence of pulmonary embolism. the prospective investigation of pulmonary embolism diagnosis (pioped ii) study, completed in , reported that multidetector ct pulmonary angiogram had % sen- sitivity and % specificity in detecting pulmonary embo- lism. notably, % of patients with a high clinical prob- ability of pulmonary embolism had a negative ct pulmonary angiogram. pioped ii and our case exem- plify the bayesian theorem of conditional probability, which states that the probability of disease depends on its pre-test probability and the sensitivity and specificity of the test. our patient had a high clinical likelihood of massive pulmonary embolism, an echocardiogram highly sugges- tive of pulmonary embolism (the mcconnell sign), but a negative ct pulmonary angiogram. in that life-threatening scenario, recent ophthalmic surgery became a relative (not an absolute) contraindication to thrombolysis. the mcconnell sign (regional variations of rv systolic wall motion abnormalities, with sparing of the apex), when prospectively tested in patients, had a sensitivity of % and a specificity of % for the diagnosis of acute pulmonary embolism. more recently, lodato et al reported the right- and left-ventricular end-diastolic dimension as the most accurate echocardiographic predictor of pulmo- nary embolism in patients referred for helical ct, but found the mcconnell sign to be most specific ( %). this finding resolved in our patient after thrombolytic therapy. unfortunately, our patient developed an unexpected com- plication of his initial diagnosis. autopsy confirmed pul- monary embolism with paradoxical embolism to the brain via a patent foramen ovale. we postulate that the initial acute pulmonary embolism resulted in high right-side pressure, leading to paradoxical embolism and subsequent cerebral infarctions. this case emphasizes the importance of understanding the specificity and sensitivity of a test and applying it appropriately to a clinical scenario. references . konstantinides sv. massive pulmonary embolism: what level of aggression? semin respir crit care med ; ( ): - . . kearon c, kahn sr, agnelli g,

invited a large group of distinguished scientists to the white house for dinner and there remarked, "i think this is the most extraordinary collection of talent, ofhuman knowledge, that has ever been gathered together at the white house, with the possible exception of when thomas jefferson dined alone." adapting this observation to the new biotechnology industry, we might say that we are today mobilizing the most amazing collection of brains for a new technology since louis pasteur worked alone. the biotechnology industry has been around for a long time, starting with the herb doctors and wine-makers ofancient civilizations. for deliberate application of the problems of science to the needs of health and the economy, however, louis pasteur is unique. he represents in one person the combination of pure research and practical application that is the hallmark of the current biotechnology industry. in pasteur's early studies he pursued the academic problem of optical antipodes, performing his classic work on the separation of dextro and levo tartaric acids. he also performed his seminal studies on the spontaneous generation of life, demonstrating that fermentation was the product ofliving cells and that life was necessary to create new life. his understanding of microbes and their behavior was the handle in his generation that recombinant dna is in ours. pasteur's genius and the smaller size of his scientific world produced a different relationship, however. pasteur personally was involved in one major industrial application after another. he discovered the cause ofthe souring ofwine and beer, thereby providing enormous economic savings for his own country as well as england and germany. he corrected the devastation of the silk industry by identifying the parasite preying on the silkworm. he developed the technique for attenuating viruses and protected chickens from cholera. he then studied the disease of anthrax and demonstrated the protection of sheep in one of the great experiments illustrating the scientific method. in the culminating act ofhis incredible career, pasteur saved the life ofa young boy who had rabies by giving him ground-up tissues from organs of infected animals. the modem technology industry parallels in uncanny ways the approach of louis pasteur. its hallmark is the continuously changing line between basic academic research and practical industrial applications. basic research in academia leads to applications in industry. questions posed by industrial problems generate new academic initiatives. to the credit of many modem biotechnology companies, they have become more permissive in allowing their scientists to publish and less secretive in regard to their procedures than the pharma- ceutical industries in the past. it is a farsighted approach, since secrets are difficult to secure and the industry itself thrives on the constant interaction with academia. this issue ofscience deals with new advances from which new medicines and industrial products may be produced. even those who do not like broccoli will have to concede that a member of the broccoli family that goes through its life cyde in weeks can provide a powerfuil research tool for plants (williams and hill). vietmeyer describes some "poor people's plants" that may provide more new bases for industrial crops than the species on which most modem agriculture now focuses. parkman discusses those diseases for which bone marrow transplantation is most appropriate, a technology whose importance is accentuated vividly by the chemobyl disaster. arathoon and his colleagues describe the improving expertise in growing large amounts of mammalian cells, a critical requirement for such products as vaccines, interferons, and monoclonal antibodies. blumenthal provides insight into the opportunities and hazards of university-industry relations, and dibner discusses the growth of biotechnology in europe. weetall and pitcher describe factors involved in scaling up an immobilized enzyme system. it is worth noting that pasteur operated with an incredible freedom not given to modem researchers. his treatment of the boy bitten by a rabid dog was done without extensive field trials, which would have delayed its application for years. his studies on soured wines and diseased silkworms were not greeted with cries that he was introducing organisms into the environment. allowing one genius unparalleled freedom is easier than attempting to control a boisterous and explosively growing technology. pasteur's willing- ness to take risks for good cause and to tackle academic and practical problems with equal enthusiasm are standards of conduct that have aged as well as the wines he preserved. -daniel e. koshland, jr. june i

faculty, thomas jefferson university; faculty, philadelphia college of osteopathic medicine; faculty, university of delaware; attending physician, family medicine, christianacare background the delaware institute for medical education and research (dimer) was founded in , with its first class entering medical school in ( years ago). at the time, as now, it was an alternative to an in-state medical school, addressing the concern of access to high-quality medical education for delaware residents in the absence of such a school. dimer initially formalized a relationship with thomas jefferson university for twenty admission slots for delawareans at jefferson medical college (now sidney kimmel medical college (skmc)). in , dimer expanded its education relationships to also include the philadelphia college of osteopathic medicine (pcom), further increasing access to medical education for delawareans. upon creation, pcom held five admission slots for qualified delaware applicants. in , that number was increased to ten. in the last years, dimer and the delaware health sciences alliance (dhsa) have worked closely together to gather data; enhance outreach to students; conduct evaluations; and bring the entire delaware healthcare together to focus on medical education and provider workforce. the dhsa was founded by core members: christianacare, nemours, thomas jefferson university and university of delaware. recently, membership has expanded to include bayhealth, pcom, and the delaware academy of medicine/delaware public health association. the dimer advantage there are five us states without an in-state allopathic medical school: alaska, delaware, idaho, montana, and wyoming. one of those, idaho, has an osteopathic school of medicine. excepting delaware, the other four are part of the wwami consortium by which the university of washington serves as their medical school. the dimer program predates wwami by two years, as the latter was started in . there are important differences between the two programs, notably, that wwami provides for the states of medical student origin to also house them for the basic sciences part of their medical education (e.g., a student from wyoming would complete a foundations phase at the university of wyoming before proceeding to the university of washington for their clinical training, and then return back to their home states in many cases for clinical experiences). as a state with no in-state medical school, this potentially presents a barrier to medical education for delaware residents. however, through its relationships with skmc and pcom, delaware has secured a minimum number of slots for qualified delaware applicants. on annual average, skmc and pcom each receive an estimated , applications for approximately slots per respective institution. as dimer applicants, delaware applications are pulled from the overall , applications received and evaluated against other delaware applicants. this significantly improves the odds of being in the applicant pool, and being offered one of or more medical school slots reserved for delaware students. dimer provides one of the best medical education admission advantages in the country for qualified applicants from the first state. delaware branch campus and residency while dimer’s charge is to ensure access to quality medical education for delaware residents, dimer’s mission and values extend beyond access. dimer and its partners are committed to providing a network of support for its students and engage students throughout the academic year in a variety of ways. ensuring delaware students understand the opportunities that are available to them through dimer’s partnerships will help to increase the qualified delaware applicant pool and ensure delaware is well-represented from all three counties. the dimer-dhsa partnership has resulted in providing personal letters to each student at the beginning of each academic year; co- hosting receptions with pcom and skmc for dimer students to network with both dimer and institutional leadership; and conducting participatory panels in every county with prospective students and families to discuss the many benefits of dimer. outreach events provide an opportunity for students to hear from a panel of experts including dimer leadership, current dimer medical students, dimer alumni, dhsa leadership, and practicing physicians as well as representatives from all our medical education partners and admissions offices. we are optimistic that through continued partnership, outreach and engagement, more delawareans will seek high quality medical education opportunities from our exceptional partner institutions. dimer is not only focused on providing medical education opportunities for delawareans but also in the retention of delaware physicians to serve our communities. dimer medical students at skmc and pcom have an opportunity to conduct their third- and fourth-year rotations at the delaware branch campus. the delaware branch campus provides medical students clinical training at christianacare, nemours / a.i. dupont hospital for children, and the wilmington va medical center, and dimer-dhsa has co-hosted graduation receptions for graduating branch campus students. in addition, pcom clinical rotations have grown to now also include bayhealth’s kent and sussex campuses. it is clear that many physicians stay to practice where they trained for residency; dimer’s relationships thus extend beyond its education partners and into delaware’s health systems. delaware residency match opportunities are not limited to delaware branch campus partners, as st. francis also has a family medicine residency program, and bayhealth is in the process of launching its own family medicine residency. this range of options will provide increased opportunity for delawareans to complete their medical training and serve their community in their home state. dimer results since , dimer has matriculated , delaware students ( students to skmc and students to pcom). of these, are male and are females. by county, originated from new castle county, while kent and sussex counties were represented by a combined total of students. dimer graduates from skmc and pcom went into primary care (n= ) and specialty care (n= ). as of , dimer students have returned to practice in delaware. twenty percent have stayed in delaware, while . % have ever practiced in delaware (i.e. . % ultimately practiced elsewhere). the full dimer anniversary report details data on the significant impact that dimer and partners are making in the first state. next steps dimer has been a successful model of delaware’s medical education program, focusing on access for delaware students. we increasingly recognize the importance of financial and debt burden, and several measures are underway this legislative session to provide greater incentives to return to the state for practice. through partnership with dhsa, dimer will continue to play an active role in the arc of education through workforce: • educating entering college students about their career choices, • assisting pre-medical students in applying to partner schools, • maintaining close touch with learners through medical school and residency, and • linking graduates to employment opportunities throughout the state upon completion of their graduate medical education. conclusion the dimer program at is revitalized and strong through its partnerships. it continues to represent high value for delawareans’ medical education. we refer readers to the full dimer anniversary report which provides more in-depth information on demographics and data on dimer graduates, as well as personal stories from state and institution leadership and dimer alumni. dimer’s partnering with the dhsa has resulted in a robust array of services intended to facilitate delawareans’ pathway to medical school and improved chances of returning to delaware to practice needed specialties in their home communities. there remain important areas of needed investment, such as more robust student financial support. we are confident that with the support of the state and our many partners, we can improve healthcare access for our communities with the best-trained medical workforce anywhere. in this way we hope to address any foreseeable barriers to a high-quality education for qualified delawareans, and to supporting a healthier delaware. references . university of washington medicine.

[from] ravages of fire and ferocious enemies." in his advice to hening on the publication he advocated another sound principal of preservation, " i shall have no doubt of the exact- ness of your part of the work, but hope you will take measures to have the typography and paper worthy of the work"—advice which hening was unfortunately not able to follow. nor did his efforts to recover the state's official archives end there. on may , , he wrote the president of the united states that thomas jefferson, monticello, jan. , , to judge george wythe, in lipscomb and bergh, ix, - .

jefferson's correspondence with his brother randolph of snowden over family finances, agriculture, spinning jennies, and the latter's domestic difficulties (now ready for publication by the mcgregor library under the editorship of pro- fessor bernard mayo);

dr. earl g. swem of the college of william and mary has sent a list of his library's jef- ferson collection to be recorded in the check list; the maryland historical society has permitted photostating of its collection; and dr. william smith mason has contributed photostats of the jefferson material in the franklin papers at yale university library. this co-operative work of institutions and individuals is bringing order back to the confusion resulting from the wide scattering of the rich treasure house that was once a single collection. in anticipation of the jefferson bi-centennial celebration in , the university of vir- ginia hopes to contribute as an aid to jefferson scholarship a printed calendar of its holdings, and an extensive checklist locating all pos- sible jefferson papers, and will welcome any lists which can be con- tributed. one is reminded, in this task of jefferson's own tireless labors on behalf of the preservation of the records of the state of virginia and of the united states; and of his labor in amassing and organizing a vast correspondence, only to have it scattered by various mischances. the man who made use of copying presses and polygraph to preserve his correspondence, and who urged printing as another means of multiplying copies, would have welcomed microfilming. that he anticipated some of the soundest principles of modern archival prac- tice is evidenced in his letter to ebenezer hazard, which is dated philadelphia, feb. , : sir i return you the two volumes of records, with thanks for the oppor- tunity of looking into them. they are curious monuments of the infancy of our country. i learn with great satisfaction that you are about com- mitting to the press the valuable historical and state papers you have been so long collecting. time & accident are committing daily havoc on the originals deposited in our public offices. the late war has done the work of centuries in this business. the lost cannot be recovered;

" by scientists and scholars were interested enough in the library so that a special committee was formed "to collect infor- mation respecting the past and present state of this country," for "the american philosophical society have always considered the antiquity, changes, and present state of their own country as pri- mary objects of their research." membership of this committee was of extremely high caliber: thomas jefferson, gen. james wilkinson, caspar wistar, charles willson peale, and jonathan williams, jr. appended to jefferson's name on the list of com- mittee members is: "president of the american philosophical society, at monticello in virginia." had jefferson lived nearer philadelphia, better results might have been obtained. as it was, the committee seems to have done little more than to circularize its intention of collecting information for the society and to reprint this circular in the transactions, volume . basically, the collection of manuscripts began in , when the historical and literary committee was formed. that remark- william e. lingelbach, "the american philosophical society library from to , with a survey of its historical background," in american philosophical society, proceedings, : - (philadelphia, ). d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .j u by c arnegie m ellon u niversity user on a pril m si / • : . • . - • & / y • £—- # . f gift of the franklin papers —courtesy of the american philosophical society d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .j u by c arnegie m ellon u niversity user on a pril jmt&tx-tfj d&jo. */ atm»t* jitter cw*wt***>/' f/tt tt&t <* *ant*/i *>f//n ja/ti* '/jrtwfta <****//*./*' fjjttertff** aj*tj at till : vafutittt', ji>/,,ofim.>t, , f laj/& t/.,tt,/,,,,u/, , fti < - - cat,:,*,» ou»r f>u s/limtjsyr'i , utl& ffu. •utt<£utif,i /actf/iiai ssmt &„<*<,<* / y u*- sitaijtoujtj t tefft# t£ j£«*fi£>*t& {t.*r- o >< n ' . / i / ^ f f fj ( ar c(u{~z?i€ ft&tumi eaifittct cotia cmj%o£sfu •ji/^m'tmtji^anj j &c if a/ of . du ponceau's questions to heckewelder —courtesy of the american philosophical society d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .j u by c arnegie m ellon u niversity user on a pril manuscripts guide able franco-american, peter stephen du ponceau, was made cor- responding secretary, and in many ways he became the committee. on august , , the committee adopted the following reso- lution : that the chairman & secretaries be authorized to solicit thro' the channel of the newspapers or other periodical publications or otherwise in such man- ner & form as they shall think most expedient the aid of those citizens & others who may be possessed of public or private documents, or be otherwise acquainted with interesting facts sufficiently authenticated & coming within the range of the objects of this committee. du ponceau personally wrote such men as thomas jefferson, elias boudinot, isaiah thomas, and david hosack, informing them of the committee's aim and asking their assistance. and the news- paper aurora, on september , , published an open letter asking the donation to the society of "the historical memoirs of individuals, public documents, scarce pamphlets, manuscript notes, public and private letters from eminent men, and from men of knowledge and observation: in short, every thing which may be considered as interesting to this country in an historical, statistical, geographical or topographical point of view." a note at the end of this "literary notice" read: "the editors of newspapers and other periodical publications, friendly to the literature of their country, are invited to give publicity to the above." although our records show that the committee was really active for only three years, the response to this appeal was little short of astounding. people in the united states were beginning to be concerned over the lack of repositories for precious manuscripts; massachusetts and new york had already organized historical societies to collect and preserve such records. that remarkable past president of the united states (and of the american philosophical society), thomas jefferson, presented such items, among others, as his collection of american indian language manuscripts; a copy of benjamin hawkins' "sketch of the creek country in the years - ," written in hawkins' hand; and memoire sur la possibilite, les avantages, et le moyens d'ouvrir un canal dans vamerique septentrionale, pour communi- quer de la mer atlantique . . . a la mer pacifique. jefferson en- dorsed the last item: "this memoire was procured for me by the chevalier bourgoyne [chevalier jean frangois bourgoing], au- historical and literary committee of the american philosophical society, min- utes, aug. , . d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .j u by c arnegie m ellon u niversity user on a pril t h e american archivist thor of the travels into spain." jefferson also urged others to leave manuscripts to the society, and such treasures as the lewis and clark journals and the william byrd journals for the history, and the secret history, of the running of the virginia—north caro- lina boundary line were acquired. m r . du ponceau, interested in the study of linguistics, solicited and received much information pertaining to the american indian from the moravian missionary johann gottlieb ernest hecke- welder and from others. the committee accepted copies of manuscripts with the same enthusiasm as it accepted originals. copies of many early laws and records of the commonwealth of pennsylvania were pre- sented by redmond conyngham. m r s . deborah norris logan and her husband, dr. george logan, presented copies of corre- spondence of their ancestor james logan, secretary to william penn. with such gifts, the manuscript collection of the library began to develop. subsequently, however, little active collecting was done. items were presented to the society, and some of these gifts were of great value and of major import. joel poinsett, for example, gave the society many valuable papers, books, and latin american items; among this group was an aztec item, the montezuma trib- ute roll, since returned to mexico. mrs. dolly payne madison presented her husband's "meteorological journal" for — , in two volumes. the primary gift of manuscripts to the library was made by charles and m a r y fox—the benjamin franklin papers. this vast mass of papers, bequeathed by benjamin franklin to his grandson, william temple franklin, was left in america with george fox, the friend of temple franklin; and after temple's death it found its home in the library. n o other gift to the soci- ety has ever matched this one; with this gift the american philo- sophical society library became a primary repository for ameri- can history. meanwhile other institutions grew and interest in the society waned. major changes in attitudes toward societies are noticeable in the emergence of state and local historical societies and the development of a great national scientific organization, the smithsonian institution. the library did not undergo major change for almost a century; it merely continued to grow. shortly after receiving the munificent bequest of richard alexander fullerton penrose and thus acquir- ing financial freedom, the society appointed a special committee on the library. its report, made in , stated that "since this d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .j u by c arnegie m ellon u niversity user on a pril manuscripts guide special committee was established, not a few members of the society have spoken of the fine reputation the library bears in their communities. upon investigation, this high repute proved almost invariably to be based upon the use of manuscripts, chiefly in the franklin collection, but also of journals of travel and of rare printed material also on similar lines." the special committee stressed that the members of the society should not think of the library contents as simply valuable and unused material relating to the history of science, but should realize that the library possesses "in the society's archives and collections an extraordinary record of intellectual interests and activities in this country." in conclu- sion, the committee's report "reiterates that an obligation rests upon the society to make known the contents of its library, for the benefit of students, in other ways than by forcing them to come to the building and consult the card catalogue." the library began in to publish a serial, the library bul- letin, also published as part of the proceedings ( — ). this publication has guided many scholars to the library. further pub- licity for the library has come from the erection of a handsome new building, across the street from philosophical hall, the home of the society, on independence square. although such publicity was good, it was judged insufficient and plans were formulated for compiling published guides to the manuscript collections. one of the major fields of the library, stemming from the inter- est of such men as thomas jefferson and peter stephen du pon- ceau, is its collection of manuscripts relating to the american indian. in addition to its indian collections built up for more than years, the library acquired in the huge franz boas col- lection of american indian linguistics. at present, these american indian manuscripts occupy roughly percent of the shelving for manuscripts. the late clyde kluckhohn, anthropologist, recom- mended that a guide to these collections be prepared, to provide eventually a complete listing of the data at hand on each language and tribe together with a brief evaluation of the reliability and significance of such data. the listing will encompass linguistic, ethnological and historical sources whether published or unpublished. the "guide" will of course indi- cate the relevant dates of the information and what topics (such as vocabu- lary, grammar, material culture, social organization, etc.) are covered . . . the "report of the special committee on the future policy of the library," in amer- ican philosophical society, year book, , p. - (philadelphia, ). the american philosophical society library bulletin was published for years, beginning in and ceasing with the issue of . d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .j u by c arnegie m ellon u niversity user on a pril t h e a m e r i c a n a r c h i v i s t availability of this "guide" will make much more economical the work of scholars and should greatly increase the utilization of the society's holdings. this guide is being prepared by john finley freeman. his report on it appears in ethnohistory (vol. , no. ; spring ). dr. freeman's guide will be a separate finding aid, complementary to but not incorporated into ours. the holdings of the library, as the special committee reported, contain "an extraordinary record of intellectual interests and activ- ities in this country." it is hoped that our projected guide will make the contents of the collections—and the collections them- selves—more widely known. for example, an outstanding collec- tion, especially in the field of american science, is the vast mass of the society's own archives. many major scientists were society members, and active members, and many of their communications and letters are available. the archives are individually cataloged through the year and are arranged chronologically for easy use. also in the library are the peale-sellers papers, a very large group of papers of such outstanding men as charles willson peale, rembrandt peale, nathan sellers, coleman sellers, and george escol sellers. these papers afford a marvelous study of a large family and its artistic, social, intellectual, scientific, and technolog- ical interests over years. charles willson peale, the famous painter, was also an outstanding naturalist and inventor. his mu- seum in philadelphia and the museums he aided his sons to set up in baltimore and new york city spread interest in natural history and natural philosophy. he invented and manufactured the poly- graph, which made copies of letters without carbon paper or let- ter-press methods; and he worked on such projects as perfecting the making of false teeth and developing the velocipede. rem- brandt peale was, of course, a famous painter and naturalist of his day. nathan sellers was a paper maker and, with his brother david, a maker of machinery. coleman sellers, a professor at the university of pennsylvania, is well represented in his correspond- ence, ca. — , with his architect son, horace wells sellers, concerning the harnessing of niagara falls to manufacture elec- tricity. george escol sellers promoted railroads in the united states and actively worked for the building of a rail line across the isthmus of panama. clyde kluckhohn, "the library's new program in american indian linguistics and ethnohistory," in american philosophical society, proceedings, : - (philadelphia, ). d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .j u by c arnegie m ellon u niversity user on a pril manuscripts guide many people still do not know that there is in the library a major collection of the papers of charles darwin and papers about the spread of his theory of evolution. this collection is supple- mented with microfilm from the darwin papers at down house, kent, england. social history is well illustrated by the extensive papers of john frederick lewis, an outstanding philadelphia lawyer and philan- thropist. his papers were acquired, chiefly, to keep them from being scrapped. and what a rich treasure for the social and intel- lectual historian this collection turned out to be! it contains rec- ords about the building of mr. lewis' great collections of medieval manuscripts and cuneiform inscriptions, now in the free library of philadelphia. activity in the intellectual life of the city, espe- cially the artistic and musical life, is well documented. there is also material on the furnishing of his great city house, his car- riages and automobiles, country estate management, and his legal activity. other manuscripts of note acquired over the years are meteoro- logical observations kept at spring mill, pa., - , by peter legaux; chief justice john marshall's opinions; the correspond- ence of general nathanael greene, of richard henry lee and arthur lee, and of general weedon; and miscellaneous volumes of notes and records kept by gotthilf heinrich ernst miihlenberg. these are a fair but very spotty sample of the holdings in the library. on such disparate groups, accumulated over so many years, whitfield j. bell and i are working. we feel that the only sen- sible approach is strictly historical. we are using the guide to the manuscript collections of the historical society of pennsyl- vania as our exemplar. our entries will be alphabetical, under author, collector, or primary person represented in the collection and will contain the same material, greatly augmented, that was furnished the library of congress for the national union cata- log of manuscript collections. where possible, we give the name of the major figure of the collection, his life span, a brief identifi- cation of him, a note on his membership in the american philo- sophical society (if he was a member), and reference to biograph- ical information about him in a standard reference work. the name of the collection or item follows, with dates and physical description, including the language, if other than english. a brief description, including major figures in the collection, is then given, d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .j u by c arnegie m ellon u niversity user on a pril the american archivist unless the entire collection has been published or there is a pub- lished guide for it. a sample entry is the following: lewis, meriwether, - . explorer, governor. aps [american philo- sophical society] . dab [dictionary of american biography]. journal of the river trip from pittsburgh to winter camp;

however, correlation between this and a replaced right subclavian artery suggests that aneurysm formation might be ob- served. as such, follow-up imaging may be important for early detection of potential aneurysmal disease. although this variant is unique, the literature describes known variations of iliac anatomy, with a reported inci- dence of in patients. tamisier et al classified these variants into three major categories: group are anomalies of origin or course, group are hypoplasia or atresia with a persistent sciatic artery, and group are isolated hypoplasia or atresia. group variants are usually asymptomatic and coincidentally found. group have a high incidence of aneurysm formation, typically presenting with acute occlu- sion or embolism. most published case reports involve this classification. - group often presents with claudication, typically in the second through fifth decades of life, and may necessitate surgical intervention. , humans may exhibit other abdominal aortic branch anomalies, with most aberrancy involving the celiac axis and mesenteric arteries. a study by koops et al examined patients who underwent celiac and superior mesenteric angiography and found aberrancy in % of patients. the most common variant cited was a replaced right hepatic artery arising from the superior mesenteric artery in % rather than the celiac axis, followed by a replaced left hepatic artery emanating from the left gastric artery in %. celiac axis anatomy variants existed in % of patients, along with a combination of these variants in %. these anoma- lies, however, are exceedingly rare in conjunction with iliac trast demonstrate various anomalies: (a) high bifurcation of artery bifurcation at l ;

faculte de medecine st-antoine, paris, france; klinikum augsburg, germany; nantes hospital, nantes, france; hopital st louis, paris, france treatment options for adults with primary refractory aml (pref aml) are extremely limited. whilst sibling allogeneic stem cell transplantation can result in long term survival most pa- tients lack a matched family donor and are destined to die of refrac- tory disease. greater availability of unrelated donors and improvements in supportive care have increased the proportion of patients with pref aml in whom allografting is technically fea- sible but the outcome of unrelated donor transplantation in this population has not been extensively studied. we therefore analysed overall survival in patients with pref aml who underwent unrelated donor transplantation between and with a me- dian follow-up of months ( - ). patients received three or more courses of induction chemotherapy. the median percentage of bone marrow (bm) blasts at transplant was %. the -year overall survival for the whole group was %. in multivariate anal- ysis, fewer than three courses of induction chemotherapy, a lower percentage of bm blasts at transplant and patient cmv seropositiv- ity were associated with improved survival. we used the prognostic factors identified in multivariate analysis to develop a scoring sys- tem. this allowed the delineation of four prognostic groups with survival rates ranging between % and %. this study dem- onstrates an important role for unrelated donor transplantation in the management of selected patients with pref aml and confirms the importance of initiating an urgent unrelated donor search in pa- tients with no matched sibling donor who fail to respond to induc- tion chemotherapy. pre-transplant factors allow the identification of patients with pref aml who are likely to benefit from unre- lated donor transplantation. hla disparity and rapid immune reconstitution do not over- come propensity to relapse in patients undergoing haploi- dentical hematopoietic stem cell transplant (hsct) with persistent disease at the time of transplant grosso, d. , alpdogan, o. , carabasi, m. , colombe, b. , cornett farley, p. , filicko-o’hara, j. , flomenberg, p. , gitelson, e. , kasner, m. , martinez-outschoorn, u. , o’hara, w. , wagner, j.l. , weiss, m. , werner-wasik, m. , flomenberg, n. thomas jefferson university kimmel cancer center, philadelphia, pa;

thomas jefferson university hospital, philadelphia, pa while increasing hla disparity is known to be associated with increased risk of significant graft versus host disease (gvhd), there is less data as to whether increasing hla disparity is corre- lated with stronger, clinically significant graft versus leukemia ef- fects. we examined a group of patients with acute leukemia undergoing haploidentical hsct to assess whether ) there was a marked difference in relapse rates based on the degree of hla mismatch and ) if early recovery of donor lymphoid subpopula- tions was associated with less relapse after hla mismatched hsct. thirty-four adult patients with aml ( ) and all ( ) underwent haploidentical hsct between and using a step process which separates the infusion of the lymphoid and myeloid portions of the graft while attempting to render the lymphocytes tolerant utilizing cyclophosphamide. the patients re- ceived x e /kg donor cd cells (dli) after conditioning with either tbi gy (n ) or fludarabine mg/m � , thiotepa mg/m � , and tbi gy (n ). two days after the dli, all patients received cyclophosphamide (cy) mg/kg � followed by a cd selected donor product. the tbi based regimen was given to % of patients with all and % with aml. we exam- ined relapse rates based on the number of antigen mismatches at a, b, cw, and drb in the gvh direction. there were no discern- able differences based on degree of hla disparity with even the most haplodisparate group exhibiting high rates of relapse when disease was present at hsct. in contrast, the presence of active leukemia at the time of hsct had far more impact on subsequent relapse rates (see table). table . outcomes based on degree of hla disparity antigen antigen antigen antigen mismatch mismatch mismatch mismatch number of patients relapsed/ total relapsed/ total relapsed/ total relapsed/ total active disease at hsct ( %) / ( %) / ( %) / ( %) n/a cr at hsct ( %) / ( %) / ( %) n/a / ( %) total / ( %) / ( %) / ( %) / ( %) we also examined the impact of immune recovery on relapse. ab- solute numbers of nk, and cd and cd t cells were examined in the first months post hsct. t cell, mnc, and total chimerism was greater than % donor-derived at the time of the assessment. for patients who did or did not relapse post hsct the median numbers of lymphoid subsets (cells/ul) were: nk ( - ) vs ( - ), cd ( - ) vs ( - ), and cd ( - ) vs ( - ) respectively. in this small series of patients treated with the step transplant method, relapse was associated more with the presence of disease at hsct than with any discern- able trend in degree of hla disparity or early immunologic recov- ery. other approaches to treat resistant leukemia are required to substantially improve disease free survival in these high risk patients. anti-hla antibodies predict graft failure, time to engraft- ment and umbilical cord unit dominance in double umbilical cord blood transplantation cutler, c. , kim, h.t. , sun, l. , sese, d. , kao, g. , vasquez, m. , armand, p. , koreth, j. , ho, v.t. , alyea, e. , soiffer, r.j. , ballen, k. , ritz, j. , milford, e. , antin, j.h. dana-farber cancer institute, boston, ma;

(p<. ; figure ). the tvt estimate was highly predictive of the final product cd + count (r¼ . , p<. ; figure ). a minimum of x cd + cells/kg was collected in . % of collections. discussion: using the correlation between the pre-collec- tion peripheral blood cd + count and the final product hpc content, the tvt formula can accurately determine the blood volume to process during apheresis collection. this has resulted in reduced apheresis time, fewer apheresis days, and less nursing time. ultimately, the tvt formula has allowed our program to improve our resource utilization by accu- rately predicating the required apheresis volume. autologous stem cell mobilization with pegfilgrastim and planned plerixafor is equally effective and safer as compared with cyclophosphamide, pegfilgrastim and plerixafor sherilyn tuazon , manish sharma , tingting zhan , margaret kasner , onder alpdogan , ubaldo martinez , dolores grosso , joanne filicko , barbara pro , john l. wagner , matthew carabasi , neal flomenberg , mark weiss . medical oncology, thomas jefferson university, philadelphia, pa;

thomas jefferson university hospital, philadelphia, pa background: autologous stem cell mobilization can be achieved using chemo-mobilization (chm) or growth factors alone (cytokine-mobilization, ctm). mobilization with peg- filgrastim and “just-in-time” plerixafor has been shown to be a successful strategy. experience with pegfilgrastim and planned plerixafor is limited. we here describe our experi- ence using two mobilization strategies with pegfilgrastim plus plerixafor (ctm) or cyclophosphamide, pegfilgrastim plus plerixafor (chm). methods: we retrospectively identified patients who received an auto-sct for a diagnosis of myeloma at tju be- tween july and june . these patients who had stem cell mobilization using either chm ( patients) with cyclophosphamide ( grams/m ), pegfilgrastim ( mg) and plerixafor ( . mg/kg once daily until target dose collected or maximum of days of apheresis), or ctm with pegfil- grastim plus plerixafor ( patients). plerixafor was only administered as an outpatient. we hypothesized that more patients in the chm group reached the prescribed total cd -positive stem cell collection as compared to the ctm group. to test this hypothesis we used the two-sample test on proportions. for the comparison of the median total cd cells/kg dose collection and the median number of apheresis days we used the wilcoxon rank sum test and the t-test, respectively. results: there was no difference in patient age at transplant, sex, and myeloma subtype. the median number of prior in- duction therapies was similar; there was no significant dif- ference in the prior exposure to lenalidomide, however as expected, bone marrow plasmacytosis was higher in the chm group ( % vs. %). in the chm group, % were hospi- talized due to complication (typically neutropenic fevers) and thus only patients ( %) received the planned dose of plerixafor as compared to % in the ctm group. there were no hospitalizations in the ctm group due to toxicity. chm was associated with a significantly higher median total cd + cell collection ( . x /kg vs. . x /kg, p¼ . ) (table ). ctm is associated with fewer collection days (median day vs. days, p¼. ) and more patients achieving the target cd + cell dose of . x /kg ( . % vs. . %, p¼. ). conclusion: the preferred method to mobilize autologous stem cells should be with pegfilgrastim and planned plerix- afor since it is able to achieve the prescribed cell dose, is associated with less toxicity and risk of hospitalization. this analysis suggests that per patients collected a total of days of plasmaphresis could be avoided if all patients were mobilized with growth factors alone. twenty years of autologous stem cell transplantation in diffuse large b-cell lymphoma e a single center experience margarida dantas brito , fernando manuel de castro campilho , rosa branca ferreira , carlos pinho vaz , susana roncon , antonio campos . serviço de hemato-oncologia, instituto português de oncologia do porto, porto, portugal;

( % ci: . , . ), decreased albumin (aor: . ( % ci: . , . ), and delay in initiation of antiviral therapy (aor: . ( % ci: . , . ) as significant risk factors for devel- opment of pneumonia (p ¼ . ), after adjusting for the virus strain. interestingly, h n infections were more prevalent in hispanic population ( , %) and required more mechanical ventilation ( , %) compared to sflu, but no significant dif- ferences were observed with respect to pneumonia or mor- tality between these two viruses. conclusions: influenza remains a significant cause of morbidity and mortality in hm patients and hsct recipients. compared to hct recipients, hm patients were more likely to progress to pneumonia, probably owing to active cancer stage and pancytopenia. h n patients did not have higher mortality rate compared to sflu in either of the groups. early antiviral therapy remains crucial in preventing morbidity in this population. favorable outcomes from allogeneic hematopoietic cell transplantation in thailand for thalassemias and hemoglobinopathies preeda vanichsetakul. blood and marrow stem cell transplant, bangkok hospital medical center, bangkok hospital group, bangkok, thailand background: thalassemia syndromes are very prevalent in many parts of the world including asia. allogeneic hemato- poietic cell transplantation (hct) is the only curative therapy accepted worldwide. objectives: to assess outcomes of hct for thalassemias and hemoglobinopathies in single medical center in thailand. methods: case series study for thalassemia and hemoglo- binopathy patients undergoing hct at bangkok hospital medical center from february thru october . results: there were totally patients. cases were thais, was french-thai, was bangladeshi, was lao, and was omani who had sickle cell disease (scd). cases were diagnosed as beta-thalassemia/hemoglobin e diseases, as transfusion-dependent alpha-thalassemia, and as scd. among hcts, patients underwent bone marrow trans- plant (bmt), patients underwent umbilical cord blood transplant (cbt), and patient underwent combined cord blood and marrow transplantation. all related donors were fully-hla-matched, had normal typing, had thal- assemia trait, and had sickle cell trait. male to female pa- tients ratio were : . patients’ ages at transplant varied from years to years months with median of years months. patient’s body weight varied from . to kilo- gram (median . kilogram). according to pesaro classifi- cation, among thalassemia patients there were class i, and class ii patients. busulfan, fludarabine, and rabbit atg were mainly used as myeloablative conditioning regimen. cyclosporine and short-course methotrexate were mainly used as graft-versus-host disease (gvhd) prophylaxis in bmt group, while cyclosporine alone was used in cbt group. cd + cell doses per kilogram body weight recipients were ranged from . to . x (median . x ) in bmt group (n¼ ), and from . to x (median . x ) in cbt group (n¼ ). complete donor engraftments were achieved in patients. mixed-chimerism states with donor predominance were present in patients from bmt and patient from cbt group. no patients experienced graft failure. neutrophil re- coveries were evident on days + to + (median day + ), and platelet recoveries were observed on days + to + (median day + ). patients had mild veno-occlusive dis- eases and were later completely reversible. no patients developed acute or chronic gvhd. there were no mortalities. patient had treatable pneumocystis pneumonia at months post cbt. median follow-up time for all patients was years ( month to years months). overall (os) and disease-free survival (dfs) were % and % for all pa- tients (n¼ ). based on risk class, the os and dfs for class i thalassemia patients (n¼ ) were % and %, and class ii patients (n¼ ) were % and %, respectively. conclusions: our experiences in hct for thalassemias and hemoglobinopathies were very favorable. regular follow-up visits are encouraged to determine long term outcomes. engraftment and immune recovery (ir) in good risk patients undergoing hematopoietic stem cell transplantation (hsct): comparison of two different approaches using cyclophosphamide (cy) for t-cell tolerization john l. wagner , dolores grosso , onder alpdogan , matthew carabasi , joanne filicko , margaret kasner , ubaldo martinez , mark weiss , neal flomenberg . department of medical oncology, kimmel cancer center, thomas jefferson university, philadelphia, pa;

pediatric stem cell transplantation, stanford university, palo alto, ca; stanford university, palo alto, ca introduction: hhv (human herpes virus ) reactivation occurs in approximately one-half of patients following allo- geneic hematopoietic stem cell transplant (hsct). the target tissues of hhv and the extent to which hhv causes dis- ease in those with viremia is not resolved. methods: biopsies or body fluid sampling are routinely performed at our center to determine the cause of otherwise unexplained end-organ disease. we describe pediatric hsct patients who were found with hhv pcr end-organ tissue positivity on these studies. of these patients, had received myeloablative conditioning, had received an unrelated donor graft, had underlying malignant disease, patients had acute gvhd, and were diagnosed with chronic gvhd. results: robust statistical partitioning identified two distinct subgroups within this population based on the highest hhv viral load in blood. in of the patients, a peak blood viral load (> , copies/ml) occurred developed while the other patients had peak blood viral loads < copies/ml. all patients received antiviral treatment to treat their viremia. at the time of biopsy and/or fluid sampling, only patient out of had a blood viral load > , copies/ml and the remainder had very low (< copies/ml) or un- detectable hhv virus in the blood despite having detectable virus in their tissues. in total, / patients biopsied patients who had tissue/body fluid viral positivity did not have con- current detectable virus in blood, in / , the blood viral load was < copies/ml, while only in one patient who had encephalitis there was a high copy number of , copies/ml detected in blood at the time of detection of the virus in the cerebrospinal fluid (csf). hhv was found in csf ( patients), bal fluid ( patients), gi tract ( patients), bone marrow ( patients), pericardial fluid ( patients), liver ( patient), and gallbladder ( pa- tients). statistical analysis showed no difference between the two subgroups with respect to age, gender, stem cell graft, stem cell donor, hla compatibility between the donor and the recipient, acute/chronic graft-versus-host disease, or survival. of note, out of patients had co-existent cmv viremia. there was a decreasing linear trend (cochran- armitage p¼ . ) in the association (fisher’s exact p¼ . ) between cmv viremia and hhv viral load group: patients with cmv viremia were in the low hhv viral load group versus patient in the high group. five of the fourteen patients died (one of whom relapsed), suggesting a high non-relapse mortality rate ( %) in this population. conclusion: end-organ disease/dysfunction with hhv positivity can persist despite a decrease in peripheral viral load after antiviral treatment. further studies will elucidate whether prolonged or intensive antiviral treatment is war- ranted in such cases. impact of adenovirus viremia in bone marrow transplant patients, - steven wu , nicole theodoropoulos , stanley i. martin , leslie a. andritsos , steven m. devine . the ohio state university college of medicine, columbus, oh;

database systems have been established within institutions for the efficient accumulation and translation of patient data into meaningful statistics that impact the process of patient care and clinical decision-making [ ]. the world wide web increasingly provides patients with affordable access to medical knowledge, though often of variable quality and navigability. with a myriad of healthcare data readily available for both patients and physicians, physicians remain responsible for the meaningful synthesis and interpretation of patient data. recent interest in patient centered outcomes and a patient-centric approach to outcomes assessment suggests that the flow of data compilation and interpretation may be reversed. rather than attempting to derive meaning from broadly collected outcomes data and wide-range outcome metrics, physicians may begin an approach to outcomes assessment by determining what outcomes are most important to their individual patients. data can then be centralized according to the outcomes that patients deem most important for their quality of life and overall health. while numerous outcome measures have been reported in the literature, minimal effort has been directed at determining whether or not these measures actually capture the specific outcome metrics most valuable to patients. to begin assessing patient expectations with regard to seeking spine care, we conducted a prospective study of what outcome metrics were deemed most valuable to patients seeking evaluation at a tertiary spine surgery center. abbreviations aaos =

provided appropriate sanction for performing the study. informed consent was waived. the investigators complied with ethical guidelines for research involving human subjects. measures the researchers developed a list of separate elements from outcome metrics widely used in spine surgery. these elements comprise the foundation measures used in compiling the visual analogue scale of spinal pain (vas), oswestry disability index (odi), short form health survey (sf- ), and euroqol five dimension questionnaire (eq- d). these common measures are widely reported in the literature for the evaluation of spine patients and have been validated in a variety of spine surgery conditions. the two-question survey explored the issues most important for consulting a neurosurgeon (table ). the first question prompted respondents to “circle the top five concerns and/or complaints that you would like addressed through your visit to our clinic.” the second question asked patients to “pick the single most important issue you would like addressed and underline it.” ) please circle the top concerns and/or complaints that you would like addressed through your visit to our clinic ) from these,

initial survey of a patient’s motivations for consulting a neurosurgeon elicits a distribution of concerns with moderate consensus (figure ). pain was the primary impetus for seeking evaluation: . % of the total surveyed group reported that pain in the back or neck was one of the major concerns for their visit (table ). similarly, this was the primary concern affecting the majority of patients. frequency of responses dropped significantly for the next responses, including weakness/numbness in the leg ( . %), problems walking ( . %), pain shooting down the leg ( . %), and problems sleeping ( . %). for the remaining options, about a quarter or less of patients indicated that one was among his or her major concerns. sexual and social issues and return to work were of very low frequency, with such activities selected by less than % of patients. figure : top concerns and/or complaints patients wanted addressed during visit outcome responses (n= ) frequency (%) pain in back/neck .

http://assets.cureus.com/uploads/figure/file/ /lightbox_ - fig .png when considering which issue was the primary concern for a patient, the highest cited responses were similar (figure ). as before, pain in the back or neck was a dominating issue as indicated by % of responders (table ). weakness/numbness in the leg ( . %), pain shooting down the leg ( . %), and problems with walking ( . %) contributed to the top four issues. these last three lower limb concerns compose approximately one-quarter ( . %) of the available responses. none of the remaining individual options assumed more than

responses selected by patients when asked to indicate single most important issues for consulting neurosurgeon. pain was consistently the most common complaint voiced by patients. axial neck or back pain was the most common complaint offered for both the top five issue and single issue questions. ludwig et al. cureus ( ): e . doi . /cureus. of http://assets.cureus.com/uploads/figure/file/ /lightbox_ - fig .png radicular pain was the third most common single complaint and fourth most common complaint from the multiple issue question. job problems were not a common complaint for this cohort of patients. only . % of patients noted that problems doing their job due to pain were among the top five issues prompting evaluation at a spine center. only . % noted this was the most important issue for which they sought evaluation. notably, only . % of the total patient sample ultimately provided a submission for the survey’s second question. the implications of this partial response rate are uncertain and varied, as this could reflect a patient’s unwillingness or inability to provide a single answer, or could represent a deficiency in survey design or execution. while the number of responses tallied for the single most important issues are deflated, the true percentage distribution cannot be determined. discussion patient-centered outcomes the results of this study indicate that pain in the back or neck is the single most important issue that prompts a patient to consult a spine surgeon. this may suggest higher utility for pain- centered validated outcomes measures, such as the vas. pain is included in the sf- , eq- d and odi as well, though it is only one of eight dimensions that contribute to the total score for the sf- , only one of five for the eq- d, and distributed throughout the sections of the odi. in the results of both survey questions, the three concerns that followed pain in the back or neck in importance to patients involved both pain and the functional consequences of their pathology: weakness/numbness in the leg, pain shooting down the leg, and problems with walking. only walking is addressed in the sf- and eq- d, while all these specific measurements are incorporated within the odi. it is possible that other outcomes measured by spine surgeons (ex: self-care, daily activities, and anxiety/depression) are not patient-centered as the majority of patients did not indicate that these issues were of primary concern. therefore, this survey raises the question of whether neurosurgical outcomes assessments should be moved closer to assessments of the issues identified as most important to patients. this may enable physicians to quantify patient expectations without relying on previously validated outcomes measurements that over- or underemphasize concerns. the patient protection and affordable care act the patient protection and affordable care act (aca) was signed into law march , and will be fully implemented on january , [ ]. since the creation of the aca, the emphasis of health care reform has shifted considerably from quantity to quality [ - ]. present efforts seek to link physician reimbursement to “value measures” which take into account both quality and cost variation [ ]. aca legislation will invest nearly $ . trillion between and in an attempt to make coverage affordable—an investment hoped to be offset in part by a reduction in medicare and medicaid spending through an emphasis on high quality and low cost care [ ]. therefore, data on effectiveness of care in everyday practice will be imperative to ensure that patients receive the highest quality rather than simply the lowest-cost care in the future. the aca introduces several changes pertinent to the present shift in focus on quality of care, three of which include the creation of accountable care organizations (acos), a national quality strategy, and the institute for comparative clinical effectiveness research. the first, acos, include a group of physicians and hospitals that will take responsibility for an expressed population of patients [ ]. acos will provide physicians and hospitals with incentive to improve integration and increase quality measurement and reporting, ultimately leading to improved outcomes and a reduction in healthcare cost. a central measurement of performance in acos is ludwig et al. cureus ( ): e . doi . /cureus. of the patient-reported outcome, which further incentivizes physicians to focus patient care and quality measures on patient-specific concerns. the second, the development of a multi-payer national quality strategy, aims to generate multi- payer quality and efficiency measures to promote value purchasing, improve safety, and provide increased health information to private and public insurers [ ]. in addition to the drive for increased comparative effectiveness research, the national quality strategy encourages increased performance reporting to increase patient’s access to information about their care and about the quality of their care. lastly, the institute for comparative clinical effectiveness research (iccer) was established by the aca “to assist consumers, clinicians, purchasers, and policy makers to make informed decisions that improve health care at both the individual and population levels” [ , ]. this builds on the american recovery and reinvestment act of that allocated . billion dollars for new comparative effectiveness research in the u.s [ ]. patient-centered outcomes research institute the patient-centered research outcomes institute (pcori) was created as part of the aca effort to foster research on informed decision-making, patient care, and re-directing research efforts to be patient-centered. the pcori has led to an increased focus on patient-centered outcome measures and on framing research in a fashion immediately applicable to patients. the foundation of the pcori approach may ultimately move outcomes assessment away from previously validated outcome measures. while many outcomes projects have been completed in spine surgery, limited research has been directed at understanding patient expectations and ensuring that outcome metrics appropriately capture the goals of patients in seeking care. outcome metrics in spine surgery spine surgery serves as an appropriate model for patient centered outcomes in neurosurgery as it is an elective procedure performed for a degenerative process. patient outcomes are therefore of utmost importance in a patient’s decision to proceed with surgery. current validated measures for patient outcomes in spine surgery include the vas [ ], odi [ - ], sf- [ ], and eq- d [ - ] (table ). the vas is a self-reported, one-dimensional pain rating scale. in contrast to the vas, the odi is a self-reported questionnaire with seven (aaos version . ) sections. the odi measures condition-specific disability and focuses on pain and can be used for both assessment and outcomes data collection. a more general measure of quality of life, the sf- , is a multipurpose, short-form health survey with items that yields an eight- scale profile of scores as well as overall physical and mental health summary measures [ ]. similarly, the eq- d is a two-part self-reported multi-dimensional questionnaire that generates possible health states based on three possible answers for five dimensions [ ]. the eq- d also measures general quality of life and yields a single utility score of - : representing death and one representing full health. vas odi sf- eq- d pain pain * bodily pain pain/discomfort functionality walking, sitting, standing, sleeping,lifting, traveling, personal care physical functioning, role-physical, general health, social

al. cureus ( ): e . doi . /cureus. of * incorporated throughout the measure these measures are frequently used in conjunction to report patient outcomes pre- and post- surgery. however, they may not all represent the outcomes most important to patients themselves. study limitations the external validity of the study is limited by the fact that it is a single-institution study with a small cohort. limiting the study to a single institution yields optimal data for the institution itself. however, to obtain more generalizable data, future multi-institutional studies should be performed. additionally, the generalizability of this study is limited by the high prevalence of psychiatric disorders amongst spine patients. dersh et al. have reported that a majority ( %) of patients with chronic disabling occupational spinal disorders (cdosd) were diagnosed with at least one current disorder (not including pain disorder), compared with only % of the general population [ ]. while the patient population in this study is composed of all patients at an academic spine surgery practice with no inclusion criteria based on diagnosis, the potential increase in psychiatric disorders amongst this population must be considered as a variable affecting patient centered outcomes. furthermore, lack of an overall calculated response-rate yields high response bias and a lower response-rate for question two [ / ( . %)] limits the internal validity of this study. a more rigorous approach to survey administration and collection should be applied in future studies to maximize internal and external validity and minimize response bias. collecting both admission and follow-up data may yield more information as to the benefits/constraints of patient-centered outcomes in the future. to obtain this data, the stringent methodology utilized by berkowitz et al. in developing a gamma knife radiosurgery registry could be applied [ ]. berkowitz et al. ensure % patient inclusion in studies by monitoring their , member patient registry through the use of clerical staff checks, server data back up, and quality assessment in six-month intervals via built-in software. similarly, the vanderbilt spine center (vsc) includes all patients undergoing spine surgery in a prospective longitudinal spine registry, regardless of diagnosis or surgical treatment through the use of registry associates, web-based research electronic data capture, and emr [ ]. the vsc employs validated outcomes measures to capture baseline, three month and month outcomes data. such strict forms of data-collection will be critical in developing accurate data to provide true patient-centered outcomes on an institution basis in the future. cost and infrastructure development remain the largest drawbacks to this methodology. results of this study knowing the issues of greatest concern to patients seeking evaluation for spinal disease will provide clinicians with the opportunity to reassess measurements of surgery outcomes. assessment of patient expectations in seeking spine care may offer a valuable means to ensure that patients have appropriate expectations in seeking surgical treatment. in this survey, the majority of patients seeking evaluation at a spine surgery center did so for complaints of pain. some concerns that are focused upon by outcome metrics used in spine surgery were not listed as primary concerns by patients. functional deficits, as outlined by the sf- measure, were not commonly noted to be primary issues for which individual patients sought treatment. similarly, return to work is often reported as a proxy for recovery after spine surgery procedures. however, this patient cohort did not note that workplace concerns were significant to their seeking evaluation. this may, in part, explain the results of a study by hodges et al. that found no correlation between osw, vas and sf- and return-to-work rates in workers’ compensation patients who underwent lumbar spine surgery [ ]. ludwig et al. cureus ( ): e . doi . /cureus. of present approaches to outcome measures in spine surgery may not be entirely representative of patient expectations. reviewing the commonly used outcome measures and comparing them to patient choices for most important issues for consulting a spine surgeon, the vas is the single most valuable outcome metric. the odi, similarly through relating pain to functional level, captures many issues deemed important by patients. conclusions it is possible that measures used today are insufficient and should be adjusted to reflect patient concerns. some present, widely-used outcomes measures report elements that patients may not find valuable. changing these measures, enforcing conformance with patient-centered choices of which outcome measures are most valuable, would be one approach to producing patient- specific outcomes measures in spine surgery. alternatively, present measures may be more comprehensive, and by reducing measures to what patients care about, the quality of data captured may be limited. routinely used and validated outcome measures may be providing a broader measure of patient outcomes. by focusing solely on what patients are interested in, physicians may be limiting their opportunity to improve patient health across multiple measures. both possibilities have implications for the future of patient-centered care in neurosurgery. as healthcare transforms under reform efforts, it is important for physicians and patients alike to recognize that what makes patients happier does not necessarily make them healthier. the goals of health care need to be defined on a national, institutional and individual basis. to determine future directions for patient-centered care, similar surveys should be rigorously conducted, reviewed, and compared to validated outcomes. a survey of both patients and surgeons should be performed to determine whether patients and health professionals differ in their perspectives with respect to quality in spine surgery. additional information disclosures human subjects: the institutional review boards of thomas

and a hut or struc- ture of some sort was chosen as an archival deposit. however, it is not generally known that the cherokee actually preserved docu- ments in their national archives before the american revolution. the cherokee were less barbarous than their indian neighbors in the eighteenth century. their achives, located at chote, the "mother town" and council place of the nation, on the little tennessee river a short distance from the site of old fort loudoun, were established before , perhaps much earlier. by the cherokee realized the wisdom of safekeeping the letters and other documents sent or given to them by the british, for they had lost more than one dispute to the british because the whites were able to produce writ- ings to support their contentions. ouconnostotah, otherwise known as the great warrior, their most powerful chief during the period on the use of wampum see frederick webb hodge, ed., handbook of american indians north of mexico, smithsonian institute, bureau of american ethnology, bulletin , pt. ii (washington, ), - . the famous james adair relates that the cherokee also preserved records of events by carving and painting "hieroglyphics" upon the stems of their pipes. samuel c. williams, ed., adair's history of* the southern indians (johnson city, tenn., ), . adair also noted (p. - ) that atta- kullakulla, the little carpenter, preserved letters from the south carolina government in a bundle, often showing them to traders to demonstrate the perfidy of that govern- ment and commenting that they ought to have been burned in the old year's fire—giving an interesting turn to an archival principle now widely discussed. northern tribes put records in the shape of red and black "hieroglyphics" on trees in the forests. plowden c. j. weston, ed., documents connected with the history of south carolina (london, ), . see e. b. o'callaghan, ed., documents relative to the colonial history of the state of new york. . . .

and a map of the proposed colony of vandalia sent to ouconnostotah by stuart. one curious item was a formal certificate attesting the election of oucon- nostotah to membership in the st. andrews club of charleston on november , . the most extraordinary document was a letter from stuart to the great warrior of june, , in which the super- intendent suggested that the chief persuade a british trader to read the letter to him. no description of the depository has been found, but it was probably ouconnostotah's own hut or the council chamber of the nation. in any case, arrangements to protect the records were not completely inadequate, since part of them are still in existence and in good condition. alas, oucconostotah and his followers, though able to defend their archives from the weather, were unable to ward off seizure by the palefaces. when the revolution broke out, the cherokee there is a brief sketch of this remarkable indian, correct except for one or two details, in the dictionary of american biografhy. his name is given therein as ocono- stota, but the form used above was most commonly used by his english contemporaries. medals were widely used by the british, french, and spanish as tokens of authority among- tribal leaders. small medals were sometimes distributed to all the tribe's warriors as decorative symbols of loyalty. in addition, the southern english colonies gave parch- ment commissions comparable to letters patent which were recognition of the rank of tribal leaders. the indians preserved these well and when going to war included them among the objects carried in the war chest. at the time ouconnostotah was stuart's guest at charleston. stuart was president of the club, and arranged for the election. no cherokee at that time could read english. communication between british of- ficials and the southern indians was commonly carried on by writing. traders and officers in the wilderness translated messages to the indians and also served as scribes for them. chiefs and warriors affixed their signatures when necessary by making their marks. d ow nloaded from http://m eridian.allenpress.com /doi/pdf/ . /aarc. . .j thw by c arnegie m ellon u niversity user on a pril the american archivist espoused the cause of "king george," and they were a serious menace on the frontiers of the southern states as late as . toward the close of that year, however, colonel arthur campbell and lieu- tenant colonel john sevier invaded the cherokee country at the head of seven hundred militiamen from the backwoods of virginia and north carolina. in a preliminary skirmish with the cherokee on the broad river of north carolina on december , a detachment led by sevier defeated seventy cherokee, and captured "all their baggage &c; in which were some of clinton's proclamations and other documents expressive of their hostile designs against us." but these papers, which apparently have disappeared, were not included in the national archives. on december the whole american force advanced into the very heart of the cherokee country, sweeping aside the feeble opposition of the indians. on december , they captured and burnt chote itself. ouconnostotah managed to elude the american riflemen, but abandoned the records of his nation in the hurry of his flight. wrote campbell to thomas jefferson, then governor of virginia, on january , , "we found in okanas- toters baggage, which he left behind in his fright, various manu- scripts, copies of treaties, commissions, letters and other archives of the nation. . . ."t fortunately for the historian, a considerable part of these records ultimately found their way into the division of manuscripts of the library of congress. jefferson forwarded a copy of campbell's letter to john hanson, president of the continental congress. in the hope that the papers seized by the militiamen would contain useful infor- mation, hanson requested that they be sent on to philadelphia. jefferson relayed this request to campbell on may . campbell was unable immediately to forward all the papers, for part of them had passed into the possession of the north carolina officers. after taking copies of certain documents which aroused his interest, camp- bell sent the originals in his possession to jefferson on june . h e also promised to try to obtain the remainder from the north caro- linians for hanson, but evidence that he was successful is lacking.

have a long-standing commitment to protecting fetal life. and yet, over the last several decades, state governments and local law enforcement are increasingly taking steps that actively undermine fetal health. through the passage of state fetal endangerment laws and the prosecution of pregnant women under stretched interpretations of existing criminal laws, states are actively creating conditions that result in poorer fetal health outcomes—including an increase in fetal and infant death. read more in vol . creating space for community representation in police reform litigation ayesha bell hardaway input from affected communities is an essential component of the reform process aimed at remedying unconstitutional police practices. yet, no court has ever granted a community organization’s motion to intervene as a matter of right in police reform, consent decree cases initiated by the department of justice. judicial opinions in those cases have truncated the federal civil rule analysis when evaluating the interests of impacted communities. thus, the most success achieved by a few community organizations has been permissive intervention or amici status. the models used by the department of justice to elicit the community perspective have been frustrating and have failed to incorporate community voice with equal weight and authority in the process. read more in vol .

exclusion criteria: antibiotic prescription, pneumo- nia diagnosis, or hospitalization in prior -days; initial therapy with multiple antibiotics; in prior -months residence in a long-term care facility or diagnosis of lung cancer, secondary malignancy, hiv/aids, cystic fibrosis, immunodeficiency. we considered the following comorbid illnesses: chronic liver, renal or lung disease; cerebrovascular disease; cardiac disease; diabetes mellitus; malignancy. follow-up claims were considered cap-related if the primary diagnosis, using the clinical classifications software, was pneumonia; septicemia; pleurisy, pneumothorax or pulmonary collapse; respiratory failure, insuf- ficiency or arrest; other lower respiratory infection. results: in total, cases met criteria; . % had

thomas jefferson university hospital, an urban academic tertiary care hospital. methods: all patients admitted between january , and december , were identified using the hospital billing system. patients with a potential cssi were identified using the specific icd- diagnosis codes. costs of care and lengths of stay, based on the hospital’s true cost accounting system, were compared by diagnosis related group (drg) between the cssi population and the non-cssi population. results: of the , patient discharges in , , ( . %) included one of the cssi diag- nosis codes; these encompassed drgs. the mean cost for cssi cases was $ , higher than for non-cssi cases, and mean los was ten days higher for cssi cases. for surgical and medical drgs, mean cost of cssi added $ , onto the cost for cases in surgical drgs compared to an average increase of $ , added to cost of medical drgs. differences in costs and los were observed in analyses by major disease categories (mdcs) and individual drgs as well. for mdcs, myeloproliferative dis- orders, multiple trauma, and diseases of the nervous system, costs were $ , , $ , , and $ , , higher for the cssi cases, respectively. this difference was also reflected in additional days of stay of , , and days, respectively. for patients with cssi, the three specific drgs responsible for the maximum total health care dollars expended were bone marrow trans- plants, rehabilitation, and small and large bowel procedures. conclusions: cssis significantly increase hospital resource consumption and costs. the difference in costs is especially pro- nounced for patients undergoing surgical procedures. results suggest that measures taken to avoid or more effectively treat cssis could yield significant savings to hospitals. pin cost-utility of chronic hepatitis “c” treatment with thymosin alpha in mexico nevárez-sida a, garcía-contreras f, constantino-casas p, castro-rios a, mould j, garduño-espinosa j mexican institute of social security,

peginterferon plus ribavirin, peginterferon plus ribavirin plus thymosin alpha- and finally, not using any drug. methods: in mexico, more that one million persons are infected with chc virus and % of them develop chronic infection that might lead to hepatic cirrhosis and other complications that affect quality of life and costs of health care institutions. cost-utility analysis was carried out using institutional perspective and time horizon of years, discount rate of % for both, costs and effective- ness. the base case was a -year-old man with chc without hepatic cirrhosis or cancer and cost and effectiveness data were taken from literature, a mexican expert panel and an on-going clinical trial, not yet reported. effectiveness data are reported in qalys and costs in usd. a decision tree using a bayesian approach and a markov model were developed. sensitivity analysis was univariate, bivariate, threshold and probabilistic. acceptability curves and health net benefits were estimated. results: triple therapy (peginterferon plus ribavirin plus thy- mosin alpha- ) was dominant over the rest of alternatives costing $ per qaly, while peginterferon plus ribavirin $ per qaly and peginterferon only $ per qaly. not using any drug was the most costly alternative with $ per qaly. sen- sitivity analysis confirmed the strength of the base study. triple therapy was not dominated in any comparative case. con- clusions: triple therapy had the best cost-utility ratio and not using any drug was the opposite, most expensive and with less utility than all the compared alternatives. although triple therapy is initially very expensive, it provides the highest gains in the long run, both in the improvement of quality of life and in saving costs. pin a comparison of methods to

Ключові слова: фермерська республіка, аграрний шлях розвитку, американська демократія, Томас Джефферсон, рання історія Сполучених Штатів Америки. Постановка проблеми. Для українського сьо- годення приклад установлення та розвитку амери- канської демократії є повчальним, особливо цікаві основи демократії, що базувалися на просвітниць- ких ідеях Томаса Джефферсона. У своїй історії су- часна Україна не мала тривалого досвіду держав- ного будівництва. Після розпаду Радянського Со- юзу для нашої країни актуальною є проблема пере- ходу від тоталітарного до демократичного устрою державотворення, тому становлення американської державної системи становить практичний інтерес. Дослідження ідеї аграрного розвитку країни, чин- ників, котрі вплинули на становлення демократич- ної теорії Томаса Джефферсона, а також історична практика формування держави в Сполучених Шта- тах Америки має велике теоретичне та практичне значення. Аналіз досліджень та публікацій. Історіогра- фія дослідження історичної постаті Томаса Джеффер- сона представлена роботами вітчизняних та закор- донних (в основному американських та російських) істориків. Потрібно зауважити, що майже всі вони присвячені аналізу політичної діяльності лідера Аме- риканської революції і Війни за незалежність та тре- тього президента Сполучених Штатів Америки. Українська історіографія - це дослідження В. М. Ка- лашнікова [ ], В. П. Газіна [ ], котрі узагальнили погляди на діяльність Томаса Джефферсона в кон- тексті ранньої історії Сполучених Штатів Америки. Серед американських дослідників Дж. Морзе, Т. Таккер, Г. Рендол, Р. Хілдрет [ ] переважають дві тенденції трактування діяльності Т. Джефферсона - більш позитивна і більш критична: роботи характе- ризуються відсутністю єдиної думки щодо ролі аг- рарної політики Томаса Джефферсона в амери- канській історії. Російські вчені-американісти, а саме: Н. Н Бол- ховітінов [ ], В. В. Согрін [ ], Г. М. Севостьянов [ ], А. І. Уткін [ ] у своїх дослідженнях позитивно оціню- вали діяльність Джефферсона, щодо втілення де- мократичних норм у життя держави. Слід зазначити, що в наукових працях мало ува- ги присвячено вивченню та аналізу демократичної теорії Томаса Джефферсона, його ідеї фермерсько- го розвитку республіки. Метою статті є дослідження та аналіз ідеї фер- мерського шляху розвитку США в контексті демок- ратичної теорії Томаса Джефферсона. Виклад основного матеріалу. Для американсь- кої історії ХvІІІ століття є переломним: колонії здобу- ли незалежність у боротьбі проти Англійської метро- полії. Лідери, які очолили Американську революцію та Війну за незалежність, були представниками аме- риканського Просвітництва. Наприкінці ХvІІІ століття в економіці Сполучених Штатів Америки основною галуззю було сільське господарство. Серед факторів, що визначали його розвиток, були такі: використання праці рабів, спе- ціалізація районів: - у колоніях Нью-Гемпшир, Массачусетс, Коннек- тикут, Вермонт, Род-Айленд займались обробкою лісу, заліза, суднобудуванням; - у колоніях Нью-Йорк, Нью-Джерсі, Пенсильва- нія на плантаціях вирощували пшеницю, льон та займались розведенням худоби, а саме: овець, сви- ней та коней; - у Джорджії, Віргінії, Меріленді, Північній та Пів- денній Кароліні вирощували тютюн, бавовну, рис, індиго (рослину, що після переробки давала стійкий синій колір). Розвиток демократичних традицій нерозривно пов'язаний з ім'ям Томаса Джефферсона, просвітни- ка, демократа, політичного та громадського діяча. Він був носієм передових ідей часів Американської революції, які втілив у свою демократичну теорію. Демократизація країни, на думку Т. Джефферсо- на, характеризувалася такими аспектами: поєднан- ням прав окремих штатів та місцевого самовряду- pdf создан испытательной версией pdffactory pro www.pdffactory.com http://www.pdffactory.com № ( ) січень-лютий р. ЕКОНОМІКА вання, суворим дотриманням Конституції, заохочен- ням сільського господарства на противагу торгівлі й промисловості і, насамперед, вірою в розумові здібності простих людей, які обирають владу. Підсумком революції ХvІІІ століття та Війни за незалежність стало завоювання незалежності аме- риканськими колоніями. Перед політичними лідера- ми Т. Джефферсоном, Б. Франкліном, Дж. Адамсом, К. Колденом, Т. Пейном постає питання становлен- ня та розвитку держави. Організацію законодавчої бази Томас Джефферсон уважав своєю головною роботою в цей час. Він розробив основоположні законодавчі документи Сполучених Штатів Амери- ки, серед яких Декларація незалежності, Білль про права, Статут про релігійну свободу у Віргінії. В ос- нові цих документів закладені його просвітницькі ідеї щодо демократичного розвитку країни. Він був при- бічником рівності людей, критикував економічну нерівність народу, англіканську церкву, політичну неправоспрожність деяких прошарків населення. У роботі простежено формування ідеї Томаса Джефферсона, що стосувалася аграрного розвит- ку. Вона базувалася на ідеях англійських філософів Дж. Локка та Монтеск'є. Т. Джефферсону імпонува- ли принципи представницького поділу влади, їх взає- мообмеження, збалансованість і рівновага. Американський демократ стверджував, що саме аграрний розвиток найбільше відповідає амери- канській дійсності. Головною фігурою американсь- кого суспільства повинен стати не промисловець, плантатор чи купець, а дрібний незалежний фермер, який користується всіма політичними правами. Демократичним ідеалом розвитку держави він вважав фермерство як єдину міцну основу респуб- ліканської форми правління. Томас Джефферсон різко критикував суспільний лад, заснований на при- ватному володінні. Уважав, що тільки на американсь- ких землях можливе встановлення "природної спра- ведливості", що означало рівне право кожної люди- ни на володіння землею. У році в проекті Конституції Віргінії Т. Джеф- ферсон запропонував програму повернення до сус- пільних надбань усіх незайнятих земель, які потрібно поділити між небагатими американськими громадя- нами. Передбачалось безкоштовне надання ділян- ки розміром акрів. Це був один із перших доку- ментів революційної пори, де вирішувалось питан- ня політичного устрою тринадцяти незалежних шта- тів. Т. Джефферсоном була висунута концепція, згід- но з якою рівний розподіл земельної власності се- ред працездатного населення держави повинен складати фундамент демократичного устрою. Т. Джефферсон наголошував, що нерівномірне розділення власності й демократія є несумісними поняттями. У листі до Дж. Медісона, професора ко- леджу Уїльяма та Мері, він закликав зробити все можливе для того, щоб обмежити економічну та по- літичну владу плантаторів та магнатів. "Земля на- дається людині як загальний набуток, щоб вона обробляла її та жила на ній" [ ]. Жодна людина не має права на жодний акр землі, самочинне присвоєн- ня землі, що має місце в суспільстві. Надання землі - це міра для заохочення старанності людей, які її обробляють. Зрозуміло, що в демократичній фермерській рес- публіці не має бути ганебного інституту рабства. Американський філософ протягом свого життя та діяльності засуджував використання рабів, перед- бачав, що в майбутньому це може призвести до конфлікту. Ним було розроблено програму поступо- вого відходу від рабства та ліквідації його. Перед- бачала вона таке: - для запобігання розповсюдженню рабства на нових територіях передбачалося заборонити ввезен- ня нових рабів до Сполучених Штатів Америки; - на території держави вже проживала досить ве- лика кількість темношкірих людей, потрібно було ви- рішити їх долю. Томас Джефферсон рішення цієї про- блеми бачив у забезпеченні дітей рабів обов'язковою безкоштовною освітою для того, щоб у дорослому віці вони могли працювати, отримувати гроші та вес- ти життя не гірше, ніж представники білої раси. Американське середовище, умови, в яких виріс Т. Джефферсон (до вісімнадцяти років він не бачив поселення більше, ніж у двадцять будинків), а та- кож спостереження над життям дрібних фермерів із нехитрим самоврядуванням зробили його аграрним демократом. Він уважав, що фермерський шлях розвитку виключає можливість масової убогості; аграрні країни, на відміну від промислових, застра- ховані від виникнення й розвитку політичної корупції, що перетворилася на велику проблему для торго- вельно-промислової Англії. Ним були визначені мо- ральні переваги фермерства: невибагливість, неви- гадливість і простота вдачі. Ідея аграрного розвитку фермерським шляхом при співвіднесенні з американською реальністю мала ряд слабких місць. Панівне становище в сільсько- му господарстві США посідали аж ніяк не фермери, а плантатори-рабовласники. У рамках "джефферсо- нівського аграрного шляху" неминуче мав виникну- ти суперечливий, приречений на розпад альянс плантаторів і фермерів, тому плантаторам відводи- лася керівна роль у створеній під керівництвом Т. Джефферсона республіканській партії. Найпростіше було б назвати аграрну теорію уто- пічною та історично обмеженою частиною філософії Томаса Джефферсона. Один із найбільш видатних теоретиків та практиків демократії небезпідставно пов'язував реалізацію демократичного ідеалу із сільською цивілізацією. Аграрна програма Т. Джеф- ферсона в кінцевому варіанті включала в себе не тільки ідею уведення мінімуму земельного володін- ня та безкоштовного надання землі для всіх грома- дян. Передбачалось обмеження власності латифун- дистів та знищення залишків феодальної системи - прав майорату та першонаслідування. Фермерська програма розвитку країни не була втілена в життя в період американської революції. У - роках фракція великих плантаторів у Вірджинській асамблеї на чолі з Е. Пендлтоном от- римала перемогу, вони домоглися прийняття рішен- ня про розпродаж західного земельного фонду. Уво- дились розміри ділянки, яку можна придбати за низь- кою ціною. Розміри були великими - акрів, що робило неможливим розвиток дрібного фермерства. Менші за розміром ділянки можна було отримати на Заході, де фермери селилися в порядку скватер- ства або за посередництва земельних спекулянтів, на правах орендаторів. У - роках Томас Джефферсон обіймав посаду президента Сполучених Штатів Америки. Він упроваджує необхідні для фермерського шляху розвитку закони щодо надання ділянки землі за зни- женими цінами (з до , доларів) та розмірами (розміри ділянок зменшувались у два етапи - у році з до , потім у році з до акрів). Були ліквідовані деякі сільськогосподарські ІСТОРІЯ pdf создан испытательной версией pdffactory pro www.pdffactory.com http://www.pdffactory.com № ( ) січень-лютий р. ЕКОНОМІКАІСТОРІЯ податки, а саме акцизні збори та прямий податок. Президент пропонував продаж ще менших ділянок, але ця ідея була відкинута членами Конгресу, се- ред яких були представники плантаторів та купців на чолі з Д. Каролліном та Діксоном. Ці реформи були проведені в період першого терміну президен- тства Т. Джефферсона. У період другого терміну його президентства в Сполучених Штатах Америки розвивається промис- ловість, скорочуються господарства дрібних фер- мерів. Президент визнає, що для розвитку держави необхідні і фермери, і підприємці. Вони будуть оп- лотом незалежності держави. Основна його діяль- ність цього періоду була зорієнтована на ліквідацію зовнішнього боргу США перед Англією, скорочення чисельності армії. Томас Джефферсон у році купує землі Луї- зіани у Франції, чим суттєво збільшує територію тодішніх Сполучених Штатів Америки. Великі роз- міри цих земель, за його задумом, дозволяли роз- селитися афро-американцям, європейцям, що пе- реїжджали до Америки, та індіанцям. Нові землі мали врятувати націю від расового конфлікту. Томас Джефферсон виступав проти тиранії та олігархії. Радикальною є його ідея про народну ре- волюцію, що визначається природним правом на- роду зняти озброєним шляхом уряд, який не вико- нує своїх обов'язків, або тирана, котрий знаходить- ся при владі. На початку ХІХ століття фермерська республіка фактично поступилася в позиціях Америці промис- ловців та фінансистів. Фермерам не судилося стати панівним прошарком Сполучених Штатів Америки. Їх чисельність стрімко зменшувалась. Усупереч своїм філософським, демократичним та політичним ідеалам Томас Джефферсон змушений був визнати необ- хідність промислового розвитку для майбутнього існу- вання держави, хоча до року застерігав Амери- ку від згубного, на його погляд, впливу промисло- вості, яка сприяла розвитку корупції та олігархії. Ідеї Т. Джефферсона щодо переваг розвитку США аграрним шляхом та ліквідації рабства були здійснені після завершення громадянської війни - рр. вже президентом Авраамом Лінкольном. Заслуга американського просвітника Томаса Джефферсона в тому, що, починаючи від року, його думки накреслили майже на сто років уперед стратегію прогресивного розвитку американського капіталізму в сільському господарстві, що втілила- ся в році з прийняттям гомстедакту. Висновки . Томас Джефферсон - американський про- світник, філософ, основоположник американської демократії. Його філософія базувалася на ідеях представників англійського та французького Про- світництва. Ним було окреслено демократичний шлях розвитку Сполучених Штатів Америки, за яким визначалася свобода людини та держави, відокрем- лення церкви від держави, усебічне розповсюджен- ня знань, розділення влади на судову, виконавчу, законодавчу та двопартійна система. . В основі демократичної теорії Т. Джефферсо- на знаходились дрібні фермерські господарства. Американський демократ уважав, що фермерів тре- ба наділити всіма політичними правами. На прак- тиці ця ідея виявилася суперечливою, вела до кон- флікту між аграріями та промисловцями. Щоб запо- бігти цьому, Т. Джефферсон відмовляється від неї в період другого терміну президентства. . Головне, чим був відзначений фермерський шлях розвитку держави, це демократизація, котра полягала в позбавленні від феодальних пережитків у вигляді законів першонаслідування, майорату та обмеження земельного володіння. . Для політичної філософії Томаса Джефферсо- на були характерними риси класичного республіка- нізму. Він підкреслював важливе значення грома- дян, які беруть активну участь у політичному житті. Вони є економічно незалежні та освічені. . Заслуга Томаса Джефферсона в історії Сполу- чених Штатів Америки полягає в утіленні демокра- тичних основ у життя американського суспільства законодавчим шляхом. Насамперед, це концепція "життя, свободи та прагнення до щастя" кожної лю- дини, не залежно від соціального стану, віку, статі та кольору шкіри. Вона викладена в Декларації не- залежності. Концепцію "освіти та духовного зростан- ня" викладено Томасом Джефферсоном у Біллі про всебічне розповсюдження знань у штаті Віргінія. Американський просвітник був противником релігій- ного фанатизму й прихильником віротерпимості, сво- боди віросповідання. Статут США р. про релі- гійну свободу містить заклик до свободи віроспові- дання, відокремлення церкви від держави. Демок- ратизація передбачала також усебічну безкоштов- ну освіту громадян. Цю ідею викладено в Біллі про загальну освіту. Ці закони становлять базу амери- канського законодавства до сьогодні. ЛІТЕРАТУРА: . Калашніков В. М.

the role of a histidine in gating sunday, february , a -pos board b access constraints and binding energetics of a potassium channel inactivation gate gaurav venkataraman, deepa srikumar, miguel holmgren. nih, bethesda, md, usa. voltage-activated potassium (kv) channels open an intracellular gate in re- sponse to changes in transmembrane voltage, allowing k þ to permeate at rates near diffusion. in some kv channels, permeation can be interrupted by the n-terminus of the protein acting as a blocking particle, binding at the intracel- lular cavity of the channel and physically obstructing the permeation pathway. despite being tetramers, kv channels require only one bound n-terminus to inactivate. in nature, inactivation is targeted by rna editing, which converts an isoleucine of the intracellular cavity into a valine. the functional conse- quence is a large increase in unbinding kinetics. how does each ‘‘wall’’ of the cavity contribute to the increase in unbinding kinetics of a single bound n-terminus? to address this question we made con- catenated shaker heterotetramers consisting of only one free n-terminus and a single isoleucine to valine mutation at position (i v), mimicking the rna editing site in humans and rodents. surprisingly, the rate of unbinding was the same for individual i v mutations in each wall; each corresponded to a decrease in binding energy of about . rt. in fact, the binding energy de- creased linearly as a function of the number of i v mutated subunits. these results suggest that despite being tethered to a particular subunit, the single in- activation particle has sufficient freedom to interact with position of each subunit with roughly equal probability. where does this freedom come from? it is expected that the inactivation gates enter the cavity through lateral ‘windows’, similarly to k þ . can our single tethered inactivation gate enter through each of the four windows of the protein? we will address this question by making individual cysteine mutations at each window and testing the inac- tivation gate’s binding kinetics after chemical modification. -pos board b gating interactions between the cytoplasmic t domain and pore of a kv channel brian urbani, manuel covarrubias. jefferson medical college of thomas jefferson university, philadelphia, pa, usa. whereas the gating roles of the voltage-sensing and pore domains of kv channels have been extensively investigated, much less is known about the mechanisms governing the regulation of gating by the cytoplasmic t domain. previous work from this lab strongly suggests that the kv . t domain un- dergoes conformational changes directly linked to gating (j. gen. physiol., : - , ); however, the structural basis of the communication between the activation gate and the t domain has remained elusive. to tackle this problem, we applied cysteine scanning mutagenesis, voltage- clamp electrophysiology, double mutant cycle analysis (dmca) and oxidizing reagents to probe specific interactions between the cytoplasmic t domain l helix, the s -s linker and s tail. the energetic impact of the mutations on activation gating is apparently small. by comparison, the energetic impact of the mutations on inactivation gating was significantly greater. dmca of k c(l )þa c(s ) revealed a significant interaction energy ( kcal/ mol), which suggests an interaction between k in the l helix and a in s . supporting this possibility, the currents induced by k c(l )þ a c(s ) are inhibited (~ % of control) by an oxidizing agent (tbuho ), whereas the single mutants are not; and the effect is reversed by the reducing agent dtt. these results indicate the formation of a disulfide bond between the interacting side chains, which is consistent with physical interaction between k (l ) and a (s ). overall, we conclude that regulation of inactivation gating by the t domain involves a physical interaction between the t l helix and the distal segment of s . supported by nih grant r ns (mc). -pos board b is the activation gate closed in kv channel closed-state inactivation? jeffrey d. fineberg, manuel covarrubias. thomas jefferson university, philadelphia, pa, usa. kv .x channel complexes including auxiliary subunits such as dpp -s and kchip undergo preferential closed-state inactivation (csi; baehring and covarrubias, , j physiol, . : - ; fineberg et al., , j gen physiol, in press). however, the molecular basis of csi in kv .x channels remains poorly understood. a key unanswered question of this problem is whether the channel’s activation is actually closed, as csi implies. we have previously proposed that csi results when the activated channel fails to open or simply prefers to close. this hypothesis specifically suggests that the intra- cellular activation gate may adopt a stable closed conformation, even under depolarized conditions that would initially favor the activated ‘‘up’’ state of the voltage sensors. to test this hypothesis, we are exploiting the trapping paradigm previously investigated by holmgren et al. to test the state of the intracellular activation gate ( , j gen physiol, : - ). essentially, if the activation gate closes behind a quaternary ammonium (qa) blocker inside the pore, the blocker cannot exit the pore; effectively, it is trapped. we are expressing the ternary kv . /i c channels (this mutation favors trap- ping) including dpp -s and kchip in xenopus oocytes. then, in the inside- out patch-clamp configuration, we are using a computer-controlled perfusion system to deliver the qa derivative decyltrimethylammonium bromide (c ) to the bath and probe the ability of the channel’s activation gate to trap c in the closed, open and inactivated states. preliminary results show that the trapping paradigm may yield an answer to the central question of this study. if the activation gate is indeed closed during csi, c trapping will only occur when the drug is applied to the conducting channel, but no trapping of c will be observed in the closed and inactivated states. supported by nih grant r ns (mc). -pos board b water at the potassium channel gate: quantum calculations show an oscillation in water structure alisher m. kariev, michael e. green. city college of the city university of ny, new york, ny, usa. quantum calculations on the open gate and the immediately surrounding re- gion of the kv . voltage gated potassium channel show that water adopts two conformations there, one when the ion is present, and another with no ion present. an energy minimum at the gate with no ion allows an ion to enter from the solution; from the gate it repels an ion in the channel pore cavity into the selectivity filter (essentially the ‘‘knock-on’’ mechanism). the pore cavity minimum can then be occupied by the ion moving from the gate minimum, leaving it available for anion from bulk, so the cycle continues. the arrange- ment of water, and the ion hydration, defines the gate energy minimum, and this in turn depends on the highly conserved prolines, especially p ( a pdb numbering), in the pvpv sequence in the gate. absent an energy minimum at the gate an ion entering from solution would be repelled back into solution by the ion in the cavity. furthermore, the ion remains hydrated by water molecules, at least more than in bulk, as it passes through the gate, based on optimizations with the ion at three different positions: ) at the gate position nearest p ) å above ) å below, this position. the open gate maintains very nearly the same protein atom positions throughout. additional calculations will be required to determine the exact interaction en- ergy with an ion in the cavity, and the amount of water that is present in the cavity. optimizations of the system configuration were done at hf/ - gsp level, with atoms ( with the ion). energy was determined using both b lyp/ - g* and bvp / - g*, but the system was too large for free en- ergy determination. -pos board b water structure at the potassium channel gate: the importance of the prolines in the pvpv sequence, as shown by computational mutations, and the role of a histidine in gating alisher m. kariev, michael e. green. city college of the city university of ny, new york, ny, usa. conservation of the pvpv sequence at the potassium channel gate has not been well understood. quantum computations (optimization at hf/ - gsp level) of the gate of the kv . channel that are presented here show that the proline-proline distances (ring atoms) are preserved as the ion moves through the gate. this calculation is supplemented by mutating one of the prolines to valine (p v, a pdb numbering for all residues in this abstract) in the computation, producing a pvvv sequence. water structure changed dramati- cally, as the protein backbone moved inward nearly å, effectively closing the channel; the proline ring n-n distance between diagonally opposite pro- lines dropped from . å (distance from optimization: x-ray distance = . å) to . å, too small to allow passage of a hydrated k þ . this suggests that the prolines play a key structural role, modulating both protein and water structure. furthermore, protonation of h may close the channel. protonation of this histidine shows it moving toward the gate by about å, which should close the gate electrostatically, while deprotonation opens the gate. protonation was calculated with two added protons, the other being accepted by e of the t intracellular moiety. when deprotonated, the histidine does not move as much as å from the x-ray position in the optimization, and is linked to e ; this accounts for the known importance of the t segment in gating. e , also of t , could accept a third proton. there is a salt bridge structure including these residues similar to the one occupying a key position in the pro- ton pathway in the hv channel. access constraints and

press, . xii + pp. illustrations and index. $ . . on october and , , a renowned group of scholars representing the academic disciplines of art, art history, classics, history, and political science convened at the american academy in rome in order to discuss the influence of the classical world—especially greek and roman texts and artistic forms—on early american leaders. taken together, the authors of this resulting collection seem to agree to disagree on the extent to which individuals like thomas jef- ferson drew lessons from the classics, ranging from “prescriptive” to “merely illustrative” (p. ix) or—as with many of them—a complex mixture of both. three of the essays focus specifically on jefferson: peter onuf’s “ancients, moderns, and the progress of mankind: thomas jefferson’s classical world”; caroline winterer’s “classical taste at monticello: the case of thomas jef- ferson’s daughter and granddaughters”; and richard guy wilson’s “thomas jefferson’s classical architecture: an american agenda.” two prominently feature him in relation to others: maurie d. mcinnis’ “george washington: cincinnatus or marcus aurelius?” and eran shalev’s “thomas jefferson’s classical silence, – : historical consciousness and roman history in the revolutionary south.” onuf and shalev share the perspective that jef- ferson loved the classics—especially in their original languages—but did not draw practical applications from what he read. in onuf’s words, “jefferson’s deepest satisfaction came from the ancients’ languages, not the wisdom of the philosophers” (p. ). in shalev’s, jefferson “saw the classics as a comforting luxury, a source of cerebral pleasure, and a symbol of social and intellectual status” (p. ). when it came to politics, especially, the authors concur that jefferson saw little to be gained from reading the classics because americans were grounding their new country’s government on people’s ability to break from the past and chart new pathways to the future. key to this transformation would be devising how to create a republican form of government based on federalism and progressivism. according to shalev, “classical antiquity was reviews in american history ( ) – © by the johns hopkins university press reviews in american history / march irrelevant to what jefferson considered the american—exceptional—situa- tion” (p. ). perhaps because their essays are more specific in their treatments of jeffer- son’s use of the classics, winterer and wilson find evidence that he borrowed directly from them as he fashioned an educational model for his daughters and granddaughters and when he designed buildings. winterer emphasizes that jefferson relied on the classics as a way of cultivating the development of “women of taste and learning” (p. ). from his travels in europe, jeffer- son saw a world “that was palpably physical and enhanced by the delights of polite society” (p. ), and the objects that he shipped back to monticello formed the nucleus of the world he envisioned for the females in his family. in winterer’s view, ellen randolph coolidge and her sisters were eventually able to break the bands of tradition and leverage their classical upbringings to achieve parity—in at least this one area—with the schooling that men of the time received. for his part, wilson emphasizes that jefferson employed mathematical proportions and hierarchies that he learned from the classics in his architec- tural styles: “jefferson looked very closely at classical precedent and usually followed the rules” (p. ). not only did jefferson rarely deviate from the geometry, composition, and proportion of classical models, but also he wanted his creations to inspire and instruct, as with his design of ten different facades for the professors’ pavilions adjacent to the lawn at the university of virginia. indeed, he helped produce “a cadre of trained architects and workers who could design and build” in the style of classical architectural forms as resur- rected by the treatises of giacomo leoni and charles errand and roland freart de chambray (p. ). two additional essays address the influence of the classics on jefferson less directly. michael p. zuckert’s essay mentions jefferson in the title, but it is less about jefferson and the classics than an argument that he followed lockean natural rights philosophy more than the views of scottish philosopher francis hutcheson (“thomas jefferson and natural morality: classical moral theory, moral sense, and rights”). that said, zuckert argues that, aside from garry wills’ thesis in inventing america, on balance there are few differences between john locke’s emphasis on natural rights and hutcheson’s moral sensitivities. in fact, zuckert concludes that, in hutcheson’s writings, “any notion that the moral sense points to a politics drastically different from that associated with lockean rights theory disappears” and that, by jefferson’s time, locke’s and hutcheson’s views had become compatible due to the writings of david hume, henry home kames, and others (p. ). “george washington: cincinnatus or marcus aurelius” by maurie d. mcin- nis focuses, in the first portion of the essay, on jefferson’s probable influences on jean-antoine houdon’s marble sculpture of washington that stands in the hatzenbuehler / influences of the classics virginia state capitol. according to mcinnis, jefferson in all likelihood met with the famous french sculptor in his paris studio and helped barter the effective combination of “the antique model with washington’s contemporary dress” that makes the sculpture so distinctive (p. ). enhancing support for this in- terpretation is mcinnis’ sensitive handling of the complex and vitally important diplomatic relations between france and the united states during washington’s first administration and jefferson’s willingness to compromise his antipathy for the society of the cincinnati with the need to placate french sensitivities. according to mcinnis, jefferson did this by commissioning a marble bust of the marquis de lafayette wearing the symbol of the society of cincinnati for the city of paris (presented in ) but requested that emblem be removed from houdon’s presentation of washington. the effect, according to mcinnis, is striking because washington appears “as cincinnatus, not washington as a member of the society of cincinnati,” since houdon’s statue presents him as a man relinquishing power (p. ). (in the second part of the essay, mcinnis shows how virginians in the s found the need to recast washington’s image as a military leader and commissioned a sculpture presenting him in the image of roman emperor marcus aurelius to accomplish that purpose.) the other essays in this volume touch indirectly on jefferson but are more expansive in their coverage, including focusing on founders such as john adams, alexander hamilton, and george mason, who embraced classical influences, or thomas paine and benjamin rush, who did not. nicholas p. cole acknowledges that the problem of pinning down the precise influence of the classics on the other founders proves to be as problematic for them as it is for jefferson (“america and ancient and modern europe”). cole finds what he terms “classical motifs” (p. ) to be prevalent in the writings of adams, hamilton, and others, but he expresses doubt that one can automatically as- sume that their readings of the classics or histories of greece and rome carried over directly to their political ideas. according to cole, the classics primarily provided an important backdrop for the founders’ criticisms of the british constitution in the period leading to the american revolution and provided inspiration for their commitment to republicanism. for his part, peter thompson (“aristotle and king alfred in america”) shifts attention from the founders’ attachment to the classics to their interest in “the ancients” more generally, especially “anglo-saxon precedent imagery [that] addressed american population growth and the corruption of government more neatly than greek or roman writing on government” (p. ). especially for jefferson, anglo-saxon precedents more than those of the classics provided “core values . . . that should be transmitted across generations,” including attachment to “the federative principle” (p. ). paul a. rahe (“cicero and the classical republican legacy in america”) and jennifer t. roberts (“pericles in america: the founding era and beyond”) reviews in american history / march concur. in rahe’s telling, patriots like paine and rush had no place for the classics because these stories idealized war, royalty, and titles. this antipathy for ancient stories was especially strong for adams, rahe argues, because rome meant empire and luxury as well as corruption, vice, and venality—callings that eventually brought the romans down: “pride drove the romans to at- tempt the conquest of an empire, and strength and courage enabled them to succeed” (p. ). just because the founders did not read the classics for precedents, how- ever, does not indicate that they did not owe them a debt. rahe emphasizes that the writings of aristotle, cicero, and others “kep[t] alive the memory of self-government through a long epoch in which despotism was the norm . . . . what made the american revolution truly revolutionary was the americans’ commitment to an understanding of man’s inalienable rights that not only distinguished them from the slave-holding, empire-building republicans of the past but also set them in opposition to the ancient example” (pp. – ). as for roberts, pericles and other greek authors played less of a role in revolutionary america than in later generations because they were too demo- cratic for the founders. regarding pericles specifically, roberts argues that he “served as an emblem of the danger of too much power in the hands of one man” during the revolutionary period (p. ); but by the nineteenth and twentieth centuries, orators (especially edward everett) invoked his name as representative “of the newly popular democratic ethos” (p. ). then, in the twentieth century, orators portrayed the athenian statesman as “the champion of an ominous militarism,” which convinces roberts that, both for the found- ers and american leaders in later periods, “modern history impress[es] itself on ancient more often than the other way around” (p. ). in the foreword to the book, andrew jackson o’shaughnessy (saunders di- rector, robert h. smith international center for jefferson studies at monticello) reveals that the authors of these essays circulated their efforts in advance in order to stimulate a discussion of their views. it would have been wonderful to hear these discussions, given the various—and often conflicting—views of the contributors and to have heard whether the give-and-take addressed important topics outside those the authors chose to address. consider, for example, the fact that only a handful of the authors touched on the topic of slavery (thompson, rahe, and mcinnis) and that none addressed the fact that, in notes on the state of virginia, jefferson compared virginian slavery directly to roman slavery. in notes, jefferson concluded, on the one hand, that roman slaves (especially in the augustan age) were much more severely treated than slaves in america; on the other, he conceded that some roman slaves became artists and scientists and were frequently tutors for roman children. “but they were of the race of whites,” jefferson concluded. “it is not their condi- tion then, but nature, which has produced the distinction.” he then observed hatzenbuehler / influences of the classics that it was the color of africans that most differentiated them from roman slaves. consequently, “among the romans emancipation required but one ef- fort. the slave, when made free, might mix with, without staining the blood of his master. but with us a second is necessary, unknown to history. when freed, he is to be removed beyond the reach of mixture” (notes, query xiv). similarly, shalev in his essay calculates that, in the run-up to the revolu- tion, jefferson was “silent” regarding classical references. especially notable for shalev is the fact that in his most important writing during the period to , a summary view of the rights of british america, jefferson “referred to and elaborated an idealized version of anglo-saxon history, and had no reference whatsoever to classical history” (p. ). shalev may be technically correct in this assertion, but it is difficult to believe that when jefferson wrote some passages he was confining his views to the saxons exclusively, as for example: “single acts of tyranny may be ascribed to the accidental opinion of a day; but a series of oppressions, begun at a distinguished period . . . too plainly prove a deliberate, systematical plan of reducing us to slavery.” in short, one wonders if slavery—whether classical or modern—surfaced as a topic for discussion among the conference attendees. finally, a quote from john adams that cole used in his essay from “dis- sertation on the canon and feudal law” ( ), reveals just how difficult it is to try to parse classical references from the texts of the founders. according to adams, american settlers were determined to break from european cor- ruptions that linked church and state: they knew that government was a plain, simple, intelligible thing, founded in nature and reason, and quite comprehensible by common sense. they detested all base services and servile dependencies on the feudal system. they knew that no such unworthy dependencies took place in the ancient seats of liberty, the republics of greece and rome; and they thought all such slavish subordinations were equally inconsistent with the constitution of human nature and that religious liberty with which jesus had made them free. [p. ] except for the religious reference at the end of the quotation, no one in early america would have agreed with adams’ statement more than thomas jeffer- son, which suggests that—perhaps not unlike the authors of these essays—the classics offered lessons for early american leaders that were complex and even, perhaps, contradictory. ronald l. hatzenbuehler is professor of history in idaho state university. he is the author of “i tremble for my country”: thomas jefferson and the virginia gentry ( ). initiation of electron transport activity and a decrease of oxidative stress occur simultaneously during embryonic heart development wednesday, february , a like ursodeoxycholic acid (udca) and tauroursodeoxycholic acid (tudca), are cytoprotective and inhibit cell death. the mechanisms associated with these distinct effects are not entirely clear. however, the effect of hydrophilic bile acids seems to be related with the blockage of a series of processes that converge on mitochondrial damage. bax is a pro-apoptotic protein that belongs to the superfamily of the bcl- proteins and is involved in mitochondrial pore formation. submicellar concentrations of cytoprotective bile acids have been shown to modulate bax concentration in mitochondria, suggesting that these molecules may interact directly with the protein. in this study, our objective was to evaluate the affinity of bile acids to recombinant bax protein, making use of fluorescence spectroscopy (fret and fluorescence anisotropy), as well as fluorescence correlation spectroscopy (fcs). our results show that the cytoprotective bile acids udca and tudca associate with recombinant bax protein with high affinity, while the cytotoxic bile acid dca only seems to be able to adsorb to the protein with much lower affinity. notably, the bind- ing site for udca seems to be located in a hydrophobic pocket of the protein. this interaction could be responsible for the disruption of bax translocation to the mitochondrial outer membrane in the presence of udca and/or tudca. supported from fct/portugal (projects ptdc/qui-biq/ / and reci/ctm-pol/ / ). t.s. and f.f. acknowledges fct grants sfrh/bd/ / and sfrh/ bpd/ / -pos board b mac inhibitors neutralize the pro-apoptotic effects of tbid pablo m. peixoto , oscar h. teijido , laurent m. dejean , evgeny pavlov , bruno antonsson , kathleen w. kinnally . natural sciences, baruch college - cuny, new york, ny, usa, national institute of child health and human development, baltimore, md, usa, chemistry, california state university of fresno, fresno, ca, usa, new york university college of dentistry, new york, ny, usa, merck serono, geneva research center, geneva, switzerland. since our initial characterization of the imacs, different di-bromocarbazole derivatives with anti-apoptotic function have been developed and tested in several mouse models of brain injury and neurodegeneration [ - ]. owing to the increased therapeutic potential of anti-apoptotic di-bromocarbazole de- rivatives, we sought to expand our knowledge of the mechanism of action of these small molecule inhibitors. we investigated the kinetics of mac inhibi- tion in mitochondria from wild type, bak, and bax knockout cell lines using patch clamp electrophysiology, fluorescence microscopy, elisa, and quantita- tive western blot analyses. our results show that imacs work through at least two mechanisms: ) by blocking relocation of the cytoplasmic bax protein to mitochondria and ) by disassembling bax oligomers in the outer membrane. a comparison of the inhibitory effects over channel conductance and cyto- chrome c release suggests that the imacs interacted with both bax and bak with similar kinetics. interestingly, wild type mitochondria were more suscep- tible to inhibition than the bak or bax knockouts. a quantitative western blot analysis showed that wild type mitochondria had lower steady state levels of bak, which suggests an uneven stoichiometry of the mac components. -pos board b tyrosine phosphorylation of mitochondrial ca d uniporter regulates mitochondrial ca d uptake jin o-uchi, stephen hurst, jyotsna mishra, xiaole xu, bong sook jhun, shey-shing sheu. depariment of medicine, center for translational medicine, jefferson medical college, thomas jefferson university, philadelphia, pa, usa. mitochondrial ca þ has a critical role for balancing cell survival and death. ca þ influx into mitochondrial matrix is mediated primarily by the mitochondrial cal- cium uniporter (mcu). however, the signaling pathways that regulate mcu channel functions via post-translational modifications of mcu are completely unknown. here we show that adrenergic signaling induces mcu tyrosine phos- phorylation and accelerates mitochondrial ca þ uptake in cardiac cells. adren- ergic signaling induces activation of proline-rich tyrosine kinase (pyk ) and translocation into the mitochondrial matrix; enhancing the interaction between pyk and mcu, which subsequently accelerates mitochondrial ca þ uptake via pyk -dependent mcu tyrosine phosphorylation. mcu contains tyrosine res- idues ( in the n-terminus, in the pore-forming region, in transmembrane do- mains and in the c-terminus), which are conserved across all eukaryotic species. among them, only of these tyrosine residues (y at n-terminus, y , and y at c-terminus in mouse mcu) remained as potential phosphor- ylation candidate sites for protein tyrosine kinases using phosphorylation predic- tion programs. we mutated these tyrosine residues to phenylalanine and generated non-phosphorylation mimetic mcu mutants (mcu-yfs). we confirmed that only two tyrosine sites were phosphorylated in response to adren- ergic stimulation in situ using cell lines stably expressing mcu-yfs. in addi- tion, overexpression of these mcu-yfs failed to increase mitochondrial ca þ uptake in response to cytosolic ca þ elevation by thapsigargin, whereas wild- type mcu transfection dramatically accelerates mitochondrial ca þ uptake compared to non-transfected cells. in summary, mcu contains pyk -specific phosphorylation site(s) and pyk -dependent tyrosine phosphorylation of mcu can modulate its channel functions and regulate mitochondrial ca þ uptake. -pos board b cardioprotective roles of neuronal ca d sensor- during stress tomoe y. nakamura-nishitani , shu nakao , shigeo wakabayashi . molecular physiology, natl.cer.cardiovasc.ctr., suita, japan, cardiac physiology, natl.cer.cardiovasc.ctrwakabayshi, suita, japan. dysregulation of ca þ homeostasis in cardiomyocytes often results in heart fail- ure. identifying molecular targets that regulate cardiomyocyte survival is of ther- apeutic importance. neuronal ca þ -sensor- (ncs- ) is an ef-hand ca þ - binding protein, which is important for excitable cell functions. we previously found that ncs- -deficient (ncs �/�) mice had excess neonatal mortality (circ. res. ).the aim ofthe present study isto examinewhether ncs- plays beneficial roles in cardiac survival during stress and the possible mechanisms un- derlying these effects. neonatal mouse ventricular myocytes orwhole hearts from wild-type (wt) and ncs �/� mice were subjected to stressors, and the resistance to stress was evaluated. ncs �/� mouse hearts were more susceptible to stress induced by oxidative impairment and ischemia-reperfusion injury. stress- inducedactivationofphosphatidylinositol -kinase (pi k)/akt signaling, a major survival pathway, was substantially reduced in the ncs �/�group, and overex- pressionofncs- ortheconstitutiveactive formofakt increased the survivalrate of ncs �/� myocytes. cellular atp levels, as well as mitochondrial respiration rates (both basal and maximal o consumption) were significantly depressed in ncs �/� myocytes; especially with oxidative stress. furthermore, intracellular ca þ handling was more easily dysregulated in stressed ncs �/� myocytes than wt myocytes. since ncs- levels were increased by stress, the data suggest that ncs- is a survival-promoting factor, which is upregulated by stress stimuli. interestingly, however,supra-physiological ncs- expression was toxic to cells. taken together, our data suggest that moderate ncs- expression during stress promotes cardiomyocyte survival by maintaining proper ca þ handling, which is required for activation of akt survival pathways and mitochondrial function. -pos board b initiation of electron transport activity and a decrease of oxidative stress occur simultaneously during embryonic heart development gisela beutner, george a. porter, jr. pediatrics, university of rochester medical center, rochester, ny, usa. mitochondria in early embryonic hearts are not thought to produce atp, yet they do produce reactive oxygen species (ros) that regulate myocyte differen- tiation. to assess changes in atp and ros generation in the developing heart, we measured mitochondrial oxygen consumption, the activity of the complexes (cx) and of the electron transport chain (etc), etc supercomplex assem- bly, and ros in embryonic mouse hearts. at embryonic day (e) . , mitochon- drial etc activity and oxidative phosphorylation (oxphos) are not coupled, even though the etc complexes are present. we show that cx- is able to accept electrons from the krebs cycle, but enzyme assays that specifically mea- sure electron flow to ubiquinone or cx- show no activity at this early embry- onic stage. at e . , mitochondria appear functionally more mature; etc activity and oxphos are coupled and respond to etc inhibitors. in addition, the assembly of highly efficient respiratory supercomplexes containing cx � , � , and � , ubiquinone, and cytochrome c begins at e . , the exact time when cx- becomes functional activated. at e . , etc activity and oxphos of embryonic heart mitochondria are indistinguishable from adult mitochon- dria. in contrast, generation of reactive oxygen species (ros), as measured with amplex red, is high at e . and drops significantly by e . , coinciding with activation of the etc. in summary, our data suggest that between e . and e . dramatic changes occur in the mitochondria of the embryonic heart, which result in a decrease of ros generation and an increase in oxphos due to the activation of cx- and the formation of supercomplexes. -pos board b the stoichiometry between micu and mcu determines the different mitochondrial ca d uptake phenotypes in heart and liver melanie paillard, györgy csordás, tünde golenár, cynthia moffat, erin seifert, györgy hajnóczky. mitocare center, pathology, thomas jefferson university, philadelphia, pa, usa. mitochondrial ca þ uptake is central to oxidative metabolism and cell death signaling. the first clues to its molecular mechanism have emerged from the recent identification of the mitochondrial ca þ uniporter’s pore forming protein (mcu) as well as its regulators. among the regulators, micu shows striking mac inhibitors neutralize the pro-apoptotic effects of tbid tyrosine phosphorylation of mitochondrial ca + uniporter regulates mitochondrial ca + uptake cardioprotective roles of neuronal ca + sensor- during stress initiation of electron transport activity and a decrease of oxidative stress occur simultaneously during embryonic heart de ... the stoichiometry between micu and mcu determines the different mitochondrial ca + uptake phenotypes in heart and liver pancan- - -ver -nagle_ p .. case report open access central pancreatectomy with pancreaticojejunostomy for an insulinoma: a case report with literature review ramzy t. nagle,* valerie e. takyi, and charles j. yeo abstract background: insulinomas are a rare entity commonly treated by resection. central pancreatectomy represents an uncommon type of resection for pancreatic lesions. case presentation: a -year-old female underwent a central pancreatectomy with roux-en-y pancreaticoje- junostomy and pancreatic stump oversew after presenting with symptoms of hypoglycemia concerning for an insulinoma. her hospital course was uncomplicated and her symptoms resolved after resection. conclusion: resection of insulinomas is the preferred approach of treatment, and resection by central pancre- atectomy is a safe option for benign lesions in the neck of the pancreas. keywords: central pancreatectomy; ct scan; insulinoma; intraoperative ultrasound; pancreatic neuroendocrine tumor; symptomatic hypoglycemia introduction pancreatic neuroendocrine tumors (pnets) are rare en- tities of the endocrine pancreas with poorly understood progression. pnets represent % of pancreatic neo- plasms and insulinomas account for % of all pnets. insulinomas are commonly sporadic but sometimes arise within the setting of multiple endocrine neoplasia- type . symptoms that accompany insulinomas are re- lated to hypoglycemia and include confusion, dizziness, behavioral changes, seizures, visual disturbances, weight gain, and, in severe cases, coma. resection of pancreatic tumors is determined by lo- cation of the lesion within the pancreatic gland. enu- cleation is the preferred approach to excising pnets; however, tumors that arise in the head of the pancreas are often resected by pancreaticoduodenectomy and lesions arising in the body or tail of the pancreas are typically resected by distal pancreatectomy. central pancreatectomy for lesions in the neck and proximal body of the pancreas is performed much less fre- quently, but has been shown to be a safe operation that preserves maximal pancreatic endocrine and exo- crine function while avoiding the morbidity and mor- tality associated with pancreaticoduodenectomy. in this study, we present a case of an insulinoma resected through central pancreatectomy with pancrea- ticojejunostomy. presentation of case the patient is a -year-old female who presented with symptomatic hypoglycemia in september . she had a - to -year history of syncopal and near- syncopal events. three years prior, she had a neurolog- ical work-up for an episode of seizures, was diagnosed with a seizure disorder, and was started on lamictal. during a recent trip to the emergency department month before presentation, her blood glucose was found to be mg/dl and a computed tomography (ct) scan of the abdomen and pelvis was obtained. although the ct was initially read as normal, there was a hypervascular mass evident in the neck of the pancreas. she underwent a follow-up octreoscan, which was negative. she subsequently had a set of syn- chronous laboratories that were significant for a serum department of surgery, thomas jefferson university, philadelphia, pennsylvania. *address correspondence to: ramzy t. nagle, bs, department of surgery, thomas jefferson university, walnut street, curtis building, suite , philadelphia, pa , e-mail: rtb @jefferson.edu ª ramzy t. nagle et al. ;

however, it appeared to traverse the entirety of the gland from the anterior to posterior pancreas, taking up most of the neck of the pancreas and dilating the pancreatic duct. given the potential risk of damaging the pancreatic duct in the process, enucleation was abandoned. distal pancreatectomy and an extended whipple procedure were also considered, but the patient would lose a large amount of normal functioning gland with both op- tions. therefore, central pancreatectomy was ultimately chosen as it allowed for the most amount of normal pan- creatic parenchyma to be preserved. the lesion proved to be a well-differentiated low- grade neuroendocrine tumor that stained positive for insulin expression on immunohistochemistry, with negative margins. her postoperative hospital course was uncomplicated and she was discharged on postop- erative day . she remained euglycemic throughout her postoperative course and her seizure medication was discontinued, under the presumption that her seizures were likely because of the insulinoma. during her follow-up visit in the office, she revealed that she was fig. . computed tomography scan at the initial presentation. fig. . intraoperative ultrasonography identified a mm hypoechoic hypervascular mass in the neck of the pancreas. no additional lesions were present. nagle, et al.;

however, these fistulas were able to be managed conservatively with drains. postoperatively, patients were found to be without evidence of pancreatic insufficiency, leading to the conclusion that central pancreatectomy is a safe procedure for benign lesions in the central pancreas. as exemplified in this case report, insulinomas may present with nonspecific symptoms for a long duration of time. localization is best achieved by ct scan and intraoperative ultrasonography. central pancreatec- tomy with pancreaticojejunostomy is a safe option for patients with insulinomas located in the neck of the pancreas. author disclosure statement no competing financial interests exist. references . bilimoria ky, talamonti ms, tomlinson js, et al. prognostic score predicting survival after resection of pancreatic neuroendocrine tumors: analysis of patients. ann surg. ;

an invaluable experimental tool for the investigation of several degenerative human conditions. studies of a number of genetically modified mice have contributed immensely to our understanding of spinal development and homeostasis (table - ). indeed, manipulations of the mouse genome through mis-expression, knocking- out, knocking-in, or the introduction of mutations into genes, as well as inbred mouse models, have transformed our understanding of spinal development and the complex functional properties of the ivd. in many cases, such mutants are also genetic models of relevant human degenerative disorders characterised by, for example, reduced bone mass (osteopenia, osteoporosis) or abnormalities in endochondral bone formation affecting development www.ecmjournal.org j melrose et al. murine spine models and growth of the skeleton (chondrodysplasias). the value of the murine model is further underscored by the high conservation of skeletal development between mice and humans, despite differences in skeletal size and time required for reaching skeletal maturity. from a regenerative perspective, understanding the regulatory molecules that are operative during such developmental processes provides information applicable to therapeutic tissue repair strategies (tessier and risbud, ). moreover, the development of quantitative histopathological scoring schemes for murine ivds have further increased the utility of the murine model for pathobiological evaluations. it is within this context that we have summarised numerous studies, whose insightful conclusions relied heavily upon the use of the mouse as an experimental model. intervertebral disc structure and comparative anatomy the spinal column was evolutionarily preceded by the notochord, a rod-like structure that provided protection to the underlying neural tube and mechanical support to the chordate organism. in higher vertebrates, which possess the advantage of distinct spinal joints (syndesmosis/symphysis) consisting of mineralised vertebral bodies joined by ivds, the notochord exits as merely a transient embryonic structure. while transient, it is crucial for mechanical support and morphogenic signalling during development. its fate is to give rise to the np, a tissue found at the centre of the ivd, distinguished for its gel-like appearance on gross examination, high proteoglycan content, and load-bearing properties. the uniqueness of the np is further exemplified by its microenvironmental conditions (i.e. hyperosmolarity, hypoxia and loading), which have guided the focus of research efforts in the quest of delineating the molecular mechanisms that underly np cell survival. such salient discoveries, facilitated by the mouse model, will be discussed in this review. the circumferential disc tissue that surrounds the np is called the af. under the microscope, the collagenous lamellae so characteristic of the af are conspicuously prominent and show a graded transition between the inner-most and outer-most regions. af cells, or annulocytes, also differ morphologically by regional location along the af (bruehlmann et al., ). together, the np and af make up the bulk of disc tissue. also important to disc anatomy are the thin layers of hyaline cartilage that form the superior and inferior boundaries, called the ceps. it is their presence that prevents the disc from applying its biomechanical forces directly against the vertebral bone. the ceps, due to their porous nature, permit diffusion and exchange of nutrients and metabolites between the vascular beds in subchondral vertebral bone and avascular compartments of the disc. this is a process facilitated by the diurnal loading and unloading of the spinal motion segments. the disc, along with the adjoining vertebrae, forms a complex polyaxial, diarthrodial joint that allows for wide ranges of -dimensional movement (shapiro et al., ). the murine ivd shares the structural characteristics described above with that of humans. an important difference to highlight, nonetheless, is that notochord- like np cells persist longer in the murine model than in humans. the murine and human ivd are embryonically derived from the aggregation of the notochord and perinotochordal mesenchyme during vertebral column development. notochordal cells produce a matrix rich in proteoglycan, important for generating central swelling pressure in the developing ivd and essential for normal np formation (adams et al., ). in humans, within to years of age after birth, the notochordal cells of the disc disappear or undergo significant morphological changes, whereas they persist throughout adulthood in the healthy murine system (trout et al., ). human np cells acquire a round, chondrocytic appearance as they age, becoming increasingly dispersed throughout the matrix. by contrast, the adult vacuolated np cells of the healthy mouse disc assemble into a central band. for reference to the histomorphology of human disc tissue, please consult the studies cited here (boos et al., ; rutges et al., ). notochordal np cells are large and vacuolated, often forming groups and clusters and described as a physaliforous cell type (pandiar and thammaiah, ). they are relatively quiescent with regards to proteoglycan metabolism, but have a marked influence on the metabolism of proteoglycans within the np (aguiar et al., ). a series of mouse mutants with defective notochordal development such as the brachyury curtailed (stott et al., ), truncate (tc) (theiler, ), pintail (pt) (hollander and strong, ), and sickle tail (skt) (semba et al., ) allow for testing of the relationship between disc health and notochordal cell defects. these mutants show acceleration in age onset-ivd degeneration correlated with the loss of notochordal cells from the np. in severe cases, the np actually does not develop (table ). accordingly, vacuolated notochord-like np cells are typically associated with a healthy ivd. there are other differences between humans and the murine system that should be taken into account. unlike humans, for one, the quadrupedal mouse does not ambulate vertically. quadrupedalism subjects the horizontally oriented spine to greater amounts of axial compression stress, which results in higher trabecular bone density when compared to humans. nevertheless, both murine and human spines are primarily loaded along the cephalic-caudal axis, and the lumbar discs of both species are loaded by ground-reactionary and endogenous forces (smit, ). the lumbar vertebrae and discs, too, are the largest in both species. when geometry is normalised, the average compressive and torsional stiffness of the murine disc is quite similar to that measured in humans (elliott and sarver, ). another obvious difference is that the mouse has an additional j melrose et al. murine spine models www.ecmjournal.org table . mouse spinal models assessing the

weight- bearing loads (elliott and sarver, ). in addition, there are important species-dependent differences in the structure of disc proteoglycans, which will be addressed in the following section. consideration of differences between murine and human proteoglycans high proteoglycan content, most notably aggrecan, is a hallmark feature of the healthy ivd, as it provides the tissue with robust load-bearing properties. structurally, the aggrecan core protein comprises globular domains: g and g , positioned at the n-terminal end, and g , positioned at the c-terminal end. the g and g domains are separated by an www.ecmjournal.org j melrose et al. murine spine models fig. . schematic depictions of the structural organisation of aggrecan, perlecan, and their ks-ii and cs chains. these schematics should be viewed as generic depictions based on reported structural data. the depictions shown are for human (a) aggrecan and (b) perlecan; murine aggrecan has a truncated ks rich region and domain iv of murine perlecan also has a kda truncation (farach-carson et al., ). (b) n- and o-sulphation positions of an hs disaccharide of perlecan in a highly modified region of the hs chain are also shown. note: while perlecan is referred to as an hs-proteoglycan, intervertebral disc cells synthesise a hybrid form where at least one of the hs chains is replaced by a cs chain. (c) typical regions of mono-, di- and non-sulphated regions of ks-ii are shown along with possible fucosylation and neuraminic acid regions (caterson and melrose, ). (d) the cs disaccharides of aggrecan are heterogenous with regard to their sulphate distributions. j melrose et al. murine spine models www.ecmjournal.org igd and the g and g domains are separated by an extended region. the extended region contains a ks attachment domain and cs attachment domains (cs- , cs- ). during its synthesis, several o-linked oligosaccharides on the aggrecan core protein are extended to form ks chains, while cs is attached by a tetrasaccharide linkage region of glca-gal-gal- xyl. several aggrecan molecules attach to ha by their g domains and lp, forming a supramolecule that holds a huge density of electro-negative charges (fig. a,c,d). these charges attract water and ions into the disc compartment through the gibbs-donnan effect, creating a hyperosmotic niche within which the resident cells must survive (silagi et al., b). unlike human aggrecan, the murine aggrecan core protein is truncated and largely devoid of a ks-rich region. complete sequencing of the murine core protein (walcz et al., ; watanabe et al., ) shows that it does not contain the consensus sequences for attachment of ks as found in human aggrecan core protein (e-(e,k)-p-f-p-s or e-e-p-(s,f)- p-s) (antonsson et al., ; doege et al., ). core protein sequencing data thus explains the reduced ks content of rodent aggrecan compared to other species (stevens et al., ; venn and mason, ). while the ks-attachment region is shorter in murine aggrecan, some ks in the igd of mouse aggrecan is thought to be present (fosang et al., ). it should be noted that species-specific differences have been demonstrated in the amino acid sequences of the aggrecan igd (flannery et al., ). these differences can have consequences on the susceptibility of this region to proteolysis by adamts- / and mmps (lark et al., ; little et al., ). yet still, the mouse aggrecan core protein ( - kda) shares . % homology with human aggrecan, and the g , g , and g domains are homologous (walcz et al., ; watanabe et al., ). in addition, the spatio-temporal distribution of aggrecan in murine disc and cartilages is similar to that observed in humans, suggesting that murine aggrecan has similar weight-bearing roles in joint tissues despite the aforementioned subtle differences in structural organisation. some differences are also evident in the gag substitution pattern of human and murine perlecan, the hs proteoglycan found in disc and cartilage (knox et al., ; melrose et al., ; melrose et al., ). perlecan has domains, labelled i-v, where domains i and v may be substituted with hs or cs (fig. b). domain i, a domain unique to perlecan, is the main region of gag substitution and contains a cluster of potential attachment sites, while domain v has additional gag attachment sites (costell et al., ; tapanadechopone et al., ). furthermore, domain iv of mouse perlecan contains less igg repeats than human perlecan. consequently, its core protein is ~ kda smaller than the human counterpart (kallunki and tryggvason, ; noonan et al., ). mouse perlecan also contains an rgd cell attachment sequence in domain iii, which is absent in human perlecan (chakravarti et al., ), although a cell adhesion site in domain iv has been identified in human perlecan (farach-carson et al., ) indicating that the overall functionality of the molecule is preserved between the species. while results obtained from murine ivds should be interpreted with these points in mind and with regard to genetic background, the ease with which the mouse can be genetically manipulated and the abundance of knowledge the murine model has offered strongly outweighs the differences described above. murine model systems transcription factors the formation of the notochord during embryonic development requires the coordinated action of many transcription factors (tessier and risbud, ). among these, foxa (ang and rossant, ), t (stott et al., ), and noto (ben abdelkhalek et al., ) are instrumental as their absence results in failure of notochord formation and np development. the loss of a notochord in foxa null mice is lethal, precluding the study of foxa and foxa and their roles in ivd formation. nevertheless, by using a conditional foxa allele in conjunction with a tamoxifen inducible cre allele (shhcreert ), foxa was removed from the notochord of e . mice, which were also null for foxa . these double mutant animals had defects in the notochord sheath, severely deformed np, increased cell death in the tail, decreased shh signalling, and resultant disruption of dorsal-ventral patterning of the neural tube. notably, embryos that were foxa null or that had foxa conditional deletion alone did not show abnormalities in the ivds, demonstrating functional redundancy (maier et al., ). once the embryonic spine has successfully developed, the maturing notochordal-np cells produce a proteoglycan-rich matrix that creates a hyperosmotic niche for resident cells. seminal studies conducted by tsai et al. revealed that the osmoadaptive transcription factor, tonicity enhancer binding protein (tonebp aka nfat or orebp), is required for survival of np cells under these hyperosmotic conditions (tsai et al., ). tonebp modulates intracellular concentrations of organic osmolytes and the hyperosmotic environment by controlling the transcription of osmosensitive and matrix-related genes such as slc a , akr b , aqp , acan, b gat , and col a (gajghate et al., ; johnson et al., ). tonebp has also been shown to regulate pro-inflammatory genes including cox- (choi et al., a), il- , and ccl (johnson et al., ). the understanding of tonebp in disc homeostasis has been elaborated upon by recent studies of tonebp- deficient mice. while complete ablation of tonebp is perinatally lethal with most embryos dying around e . , embryonic investigations have revealed that tonebp loss causes developmental delay of the spinal column and aberrant levels of the notochord markers shh, t, ca , and vimentin. interestingly, this study www.ecmjournal.org j melrose et al. murine spine models raised an interesting possibility that shh receptor ptch is a transcriptional target of tonebp (tessier et al., ). subsequent studies of adult tonebp haploinsufficient mice showed accelerated age-related disc degeneration and matrix fibrosis, with greater propensity for annular and endplate herniations. moreover, tonebp haploinsufficient mice displayed disc compartment-specific effects evidenced by increased expression of actin cytoskeleton-related genes in af cells and reduced expression of immune and pro-inflammatory genes in np cells (tessier et al., b). an important determinant of the np niche is its avascular and hypoxic nature. this notion of limited oxygen availability has led to the general belief that np cells primarily produce energy via glycolysis with little dependence on mitochondrial metabolism. remarkably, however, recent investigations of mitoqc reporter mice have conclusively shown that np cells possess mitochondrial networks consisting of numerous tubular mitochondria which undergo increased mitophagy with aging, emphasising the importance of the mouse model as a key investigational tool. furthermore, mitochondrial fragmentation, morphology, and mitophagic flux was shown to be mediated by hif- α and mitochondrial receptor bnip (madhu et al., ). among its numerous functions, hif- α regulates np cell metabolism under hypoxic conditions by coordinating interactions between glycolysis and the tca cycle (madhu et al., ). hif- α also contributes to the transmembrane balance of high intracellular h+ and lactate concentrations by mediating expression of mct (silagi et al., ) and the bicarbonate recycling enzymes carbonic anhydrase and (silagi et al., a). mct null mice show classical signs of disc degeneration with increased aggrecan degradation, elevated mmp , and collagen x levels (silagi et al., ). as one would thus expect, analyses of the ivds of hif- α conditional knockout mice in either shh or foxa expressing cells has demonstrated early-onset postnatal degenerative features with notochordal cell loss and severely prominent fibrosis (merceron et al., ; wu et al., ). hif- α also regulates galectin- , a highly expressed lectin in the ivd. while its in vivo role in this tissue is poorly understood, in vitro studies suggest that galectin- promotes np cell survival under conditions of oxygen deprivation. in np cells, suppression of galectin- activity promotes the expression of fasl, an inducer of apoptosis, suggesting that this hif- α-regulated lectin plays a role in np cell survival (zeng et al., ). hif- α and hif- α have also been shown to negatively regulate the expression of ank and thereby control local levels of pyrophosphate, an important inhibitor of tissue mineralisation (skubutyte et al., ). therefore, the hypoxic environment and the consequent role of hif transcription factors is critical to the np cell identify and function. the importance of low oxygen tension is further accentuated by recent investigations of tnmd-null mice. tnmd is an anti-angiogenic factor with robust af expression, especially by the outer annulocytes. its loss (tnmd−/−), as well as a double knockout with its homologue, chondromodulin i (tnmd−/−;chm −/−), results in vascular invasion of the af tissue, macrophage infiltration, and accelerated disc degeneration with hypertrophic cells. the double knockouts show greater progressive changes including ectopic bone formation (lin et al., ). central regulators of spinal development and skeletogenesis include a number of sox transcription factors. sox and sox / have been shown to cooperate via super-enhancers to drive chondrogenesis (liu and eronique lefebvre, ); hence, these three sox proteins are often referred to as the sox trio. the importance of the sox family members is made apparent by the various human skeletal diseases caused by their heterozygous mutations. mutation of a copy of sox or disturbance to its regulation causes campomelic dysplasia (wunderle et al., ); haploinsufficiency of sox causes lamshf, a neurodevelopmental disorder associated with variable skeletal abnormalities (lamb et al., ). while sox / are functionally redundant, their dual ablation prevents formation of the notochord sheath, evidenced by notochordal and peri-notochordal downregulation of collagen ii, versican, and aggrecan. these aberrations are also met by subsequent apoptosis of notochord cells and culminate in formation of a severely defective spine lacking np (smits and lefebvre, ). similarly, mouse embryos null for sox show notochord disintegration as early as e . (barrionuevo et al., ) and deletion of sox in the disc (acancreert sox fl/fl) results in degeneration (henry et al., ). early degeneration of the cep is the first conspicuous change seen in acancreert sox fl/fl mice, followed by degeneration of all disc compartments and severe disc collapse involving apoptosis and progressive loss of disc cells. importantly, transcriptomic profiling indicated that sox has distinct compartment- specific functions (tsingas et al., ). the sox trio also works with paired box transcription factors pax and pax , which are essential for af development (peters et al., ; sivakamasundari et al., ). despite the key importance of the sox genes in disc homeostasis and skeletogenesis, the precise roles that many of these transcription factors play in the adult disc remain elusive, representing a necessary avenue for future investigations. in addition to pax / and the sox trio, among others, the mkx and scx transcription factors are key to af development. lineage tracing studies have shown that an af multipotent progenitor population co-expressing sox and scx contribute to the formation of the inner and outer af (sugimoto et al., ). furthermore, lineage studies have revealed that scx-expressing cells drive af regeneration after annular puncture of neonatal discs. this finding offers an interesting direction for future disc regeneration therapies, highlighting the importance of genetic j melrose et al. murine spine models www.ecmjournal.org lineage tracing studies in mice (torre et al., ; torre et al., ). by a similar token, complete knockout of mkx results in smaller collagen fibril diameter in the outer af and early onset disc degeneration. transplantation of mkx-overexpressing mscs into the injured af of a tail-loop mouse model was shown to promote af regeneration with abundant collagen fibril formation (nakamichi et al., ). it is worth noting here that mice deficient in the transcription factor bach- are less impacted by annular puncture. bach- deficiency results in increased levels of ho- , which protects disc cells from oxidative stress (ohta et al., ). recent investigations by alvarez-garcia et al. revealed that all compartments of the ivd express foxo , foxo , and foxo . downregulation of foxo levels, notably foxo and foxo , was observed during aging, preceding major degenerative changes seen on histology (alvarez- garcia et al., ). simultaneous knocking out of these three foxo isoforms using col a cre resulted in a progressive increase in np cellularity, due to increased proliferation, and an associated increase in disc height. by and months, these discs began to show marked features of degeneration and a severe kyphosis. interestingly, analysis of acancreert driven triple knockout at skeletal maturity showed degenerative changes more conspicuous in the np than the af, while analysis of single gene knockouts showed that foxo and foxo are the dominant members, playing a role in mediating autophagy and antioxidant defences in np tissues (alvarez-garcia et al., ). development of the axial skeleton relies on the tight spatio-temporal control of hox transcription factors. the hox genes that encode these factors differentially control the proliferation rates of the mesenchymal condensations that give rise to the vertebral cartilages. for instance, mutations in the homeobox containing gene hoxb- (hox . ) causes overt changes in the axial skeleton that are characterised by a transformation of the second cervical vertebra from axis to atlas (ramfrez-solis et al., ). similarly, hoxd- gene (hox- . ) disruption causes anterior transformations of the atlas and axis and a drastically remodelled craniocervical joint (condie and capecchi, ). the hox and hox genes are also involved in the global patterning of the axial and appendicular skeleton. lumbar vertebrae fail to develop with loss of hox , while loss of hox results in formation of lumbar vertebrae in the place of sacral vertebrae (wellik and capecchi, ). cell signalling pathways an intricate balance of morphogenic signals is required for proper embryonic development of the ivd. a centrally important morphogen in this process is notochord-secreted shh, which not only patterns surrounding embryonic structures such as the neural tube and af anlagen, but is also required for maintenance of the notochord itself and subsequent formation of the np. hedgehog proteins interact with the , -disulphated non-reducing terminal glycans of cs chains in aggrecan and the hs chains of perlecan and this may localise shh in tissues, aid in the formation of shh gradients, and regulate shh cell signalling (bandari et al., ; cortes et al., ; ortmann et al., ). the necessity of shh for disc development was demonstrated by choi and harfe who removed shh signalling from shh-expressing cells, including the notochord and floorplate, using a floxed mouse allele of the shh receptor smo and shhgfpcre (choi and harfe, ). conditional ablation of smo during early embryogenesis resulted in defects in ivds and vertebrae formation; however, removal of smo once the notochord sheath had formed did not alter disc development, highlighting the importance of the notochord sheath during spinal patterning. the role of shh in ivd development and postnatal homeostasis has been investigated and reviewed by dahia and colleagues (rajesh and dahia, ). the function of wnt/β-catenin signalling in the regulation of ivd development and degeneration has been examined in wnt/β-catenin reporter (topgal) mice (dahia et al., ; kondo et al., ). it was noted that during embryonic stages, wnt signalling was active in the ceps and af but very low in the np. postnatally, however, wnt signalling by np cells was found to increase. overexpression of β-catenin in both col a and col a -expressing disc cells resulted in af disorganisation, hyperplasia, and osteophyte formation in adult mice (kondo et al., ; wang et al., ). deletion of β-catenin in col a -expressing cells in -day-old mice resulted in accelerated maturation of subchondral bony endplate by weeks of age. a later study using topgal mice showed that wnt signalling in the np declines with aging in both lumbar and caudal discs (holguin et al., ). of note, wnt signalling positively regulates shh, which activates the expression of differentiation factors and cell proliferation in np cells, but undergoes a decline with ivd maturation (winkler et al., ). wnt and shh are poorly soluble proteins and in order to establish gradients of these morphogenetic components in tissues, perlecan may have a transporter role. indeed, wnt binds to the ldl receptor-like domains of perlecan domain ii (matsuo and kimura-yoshida, ). growth factors stimulate matrix production and np cell proliferation. ctgf, aka ccn , serves key functions in this regard. ccn binds to ldl receptor lrp , which is homologous to domain ii of perlecan (segarini et al., ), as well as integrins α β and αvβ (tran et al., ). ccn modulates bmp, tgf-β, and wnt signalling to coordinate chondrogenesis and angiogenesis during skeletal development (abreu et al., ; mercurio et al., ), and more recently in the prevention of degenerative disc disease (matta et al., ). deletion of the ccn gene in notochord-derived cells results in age- associated degeneration of ivds, decreased levels www.ecmjournal.org j melrose et al. murine spine models of aggrecan and collagen ii, and increased levels of collagen i within the np (bedore et al., ; tran et al., ). the ability of ccn to regulate the composition of the ivd suggests that it may be a clinical target for the treatment of ivd degeneration. the tgf-β superfamily are secreted proteins that play crucial roles in the determination of the notochord lineage and in skeletal development, growth, and cell differentiation. the importance of these signalling proteins in ivd development was well-demonstrated by the constitutive conditional knockout of the tgf-β type ii receptor (col acre;tgfbr fl/fl). these mutant embryos showed vertebrae deformities and ivds that were either completely lost or reduced due to af defects (baffi et al., ; baffi et al., ). subsequent microarray analyses of the embryonic tgfbr -null discs revealed that the expression profiles were similar to that of vertebrae profiles (sohn et al., ), and identified the transcription factor, avian erythroblastosis virus e- oncogene homologue (erg), as a player in af differentiation. accordingly, the function of tgf-β in disc development is thought to involve the induction of af differentiation from the sclerotome while inhibiting chondrocyte differentiation of the presumptive ivd. more recently, acancreert ;tgfbr fl/fl mice were generated to study the role of tgfbr in adult tissue. deletion of tgfbr at weeks-of-age resulted in progressive degeneration underscored by disorganisation of af lamellae with thinning of af collagen bundles, delayed bony endplate formation, and dystrophic calcification of the disc by months of age (alkhatib et al., ). these studies highlight that tgf-β also plays a clear role in ivd homeostasis postnatally. tgf-β signals through smad and ap- , positively regulating ccn expression in the np and may represent a limited reparative response in ivd degeneration (tran et al., ). smad null mice are smaller in size, show spinal malformations and kyphosis, exhibit alterations in cep structure, and show decreased ivd proteoglycan and collagen content (li et al., ). tgf-β/smad signalling in np cells regulates the expression of β- , - glucuronosyltransferase- (glcat- ), an important regulator of gag synthesis, which may partly explain the reduced gag levels in smad knockout mice (wu et al., ). it may be concluded that ccn and tgf-β are actively secreted by notochordal cells and that these direct resident disc cell populations in the maintenance of ivd homeostasis. additional growth factors that have a key role to play in disc homeostasis include igf- , fgf, and gdf . igf- and its receptor (insulin-like growth factor- receptor, igf r) have regulatory roles over extracellular matrix (ecm) synthesis and crucial roles in the maintenance of ivd homeostasis. igf- and tgf-β both regulate mmp- production by np cells (pattison et al., ). the ivds of igf r+/− mice display greater histopathological scores of degeneration, reduced collagen ii and proteoglycan levels, and elevated mmp (li et al., ). aberrations to fgf-fgfr signalling are responsible for a diverse group of skeletal disorders including those that afflict the axial skeleton (table ). polymorphism in gdf has been associated with disc degeneration in humans (huang et al., ); accordingly, ivds in gdf knockout mice show decreased proteoglycan content and loss of water binding, evident from reduced t -weighted signal intensity of lumbar levels (li et al., ). mutations in genes that cause over-stimulation of signalling pathways involved in cell growth and differentiation often yield predispositions to oncogenesis and other clinical pathologies, including skeletal abnormalities. mutations in nf , which encodes neurofibromin, a gtpase-activating protein that downregulates the ras pathway, causes nf . nf is a disorder characterised by generalised focal bony lesions, dystrophic scoliosis, and tibial pseudoarthrosis. to investigate the aetiology of the skeletal abnormalities associated with nf , researchers used col a cre;nf fl/fl mice to silence nf in axial and appendicular osteochondroprogenitor cells. these mice displayed progressive scoliosis, kyphosis, short stature, and ivd defects, closely recapitulating the clinical features of nf in human patients. interestingly, inhibition of ras/erk by lovastatin mitigated the phenotype of these mice, suggesting that activation of the ras/erk pathway by nf loss-of-function is in part responsible for these spinal defects (wang et al., ). similarly, tuberous sclerosis complex (tsc) is an autosomal dominant disorder characterised by mutations in tsc or tsc that leads to hyperactivation of mtor. patients with tsc suffer from benign tumours known as tubers that affect several organ systems including sclerotic bone lesions. tsc null mice show congenital spinal defects marked by kyphosis and a degenerative disc phenotype (yang et al., ). recent studies of phlpp , a phosphatase that negatively regulates akt signalling, suggested that this axis may play a role in disc degeneration. disc injury in phlpp null mice lead to akt activation and cell proliferation and showed long-term positive effects on preserving cellularity and matrix homeostasis, implying that it can be explored as a therapeutic target (zhang et al., ). ulici et al. have also recently reported the skeletal phenotype of jnk and jnk double- knockout mice (col a cre; jnk fl/fl/jnk −/−). these mice showed a severe and early onset scoliotic phenotype and vertebral and disc fusions (ulici et al., ). a murine model of human progeroid syndrome was developed by genetic ablation of ercc , a gene that encodes a functional protein of the xpf-ercc nuclease, ercc (niedernhofer et al., ) and contributes to the repair of double stand breaks. haploinsufficient ercc show advanced degenerative changes in the vertebral bodies and ivds, including reduced proteoglycan content, increased apoptosis, and p positive cells, consistent with accelerated j melrose et al. murine spine models www.ecmjournal.org senescence and aging (vo et al., ). further studies linked nf-κb-mediated signalling to the ercc +/− phenotype (nasto et al., ). extracellular matrix and its turnover in a polyaxial diarthrodial joint, the disc allows the spine to flex, extend, and rotate, with the np functioning as a central fulcrum (shapiro et al., ). this system is made possible by the relationship between the swelling forces of the np due to its proteoglycan-rich matrix and opposing counter- forces provided by the concentric collagenous lamellae of the af. therefore, matrix changes and degradation often define degenerative disc pathology (table ). high concentrations of aggrecan and ha are characteristic features of the ivd. mice lacking has show prominent vertebral body defects underscored by a lack of endochondral ossification, decreased matrix deposition, and increased cartilage cellularity. perhaps counter to what one might expect, np cellularity was increased with copious vacuolated cells. since ha can interact with chondrocytes through cd , rhamm, and other cell surface receptors, it is possible that lack of ha induced a state of proliferation and differentiation in the targeted cells of these mice (roughley et al., ). chloe b mice have a knock-in mutation in the acan gene that changes the sequence in the igd from dipen↓ffg to dipen↓gtr for the purpose of blocking mmp-dependent cleavage of aggrecan (little et al., ). these mice do not show major alterations in skeletal development, and their ivds have no obvious developmental abnormalities. adamts- is the major aggrecan degrading metalloprotease in murine articular cartilage and disc (stanton et al., ), while adamts- is the major aggrecanase in murine growth plates (glasson et al., ). adamts- knockout mice, surprisingly, do not show any defects in skeletal development, growth, or remodelling, and no alterations in the growth of their long bones (glasson et al., ). likewise adamts- knockout mice have no skeletal developmental abnormalities, although deletion of adamts- effectively prevents cartilage destruction in a murine osteoarthritis model and is shown to protect from chronic tobacco smoke-induced disc degeneration (ngo et al., ). these findings are consistent with the view that adamts- is largely responsible for the turnover of murine aggrecan model phenotype references has knockout vertebral body defects, decreased matrix

-dependent aggrecanolysis predominates over adamts- in mouse cartilaginous tissues due to an absence of highly sulphated ks chains in the murine igd (stanton et al., ; stewart et al., ). these mutants suggest that preventing aggrecan turnover do not lead to major effects on skeletogenesis and disc health. naturally occurring and engineered mutations in the gene encoding perlecan (hspg ) show unequivocally that perlecan is essential for cell growth, differentiation, and the function of cartilaginous tissues (arikawa-hirasawa et al., ; arikawa-hirasawa et al., ). both the core protein and the gag chains confer perlecan’s ability to modulate these processes. when substituted with hs, perlecan domain i promotes binding to laminin- and collagen iv. perlecan can also interact with a number of fibrillar or cell attachment molecules in the ecm and thus plays important roles in its organisation (melrose et al., ). the hs side chains of domain i of perlecan act as low affinity co-receptors for growth factors, such as fgf- , - , - and - , and a core protein receptor for fgf- has also been reported (ghiselli et al., ; mongiat et al., ). this complex formation is important for the correct presentation of the fgfs to fgfrs, their subsequent oligomerisation, activation to initiate cell signalling through the cytoplasmic tail of the fgfrs, and subsequent downstream effects on cell proliferation and differentiation (chang et al., ; chuang et al., ; knox et al., ; knox and whitelock, ). perlecan contains multiple modules that are homologous to the ldl receptor (murdoch et al., ; noonan et al., ). when expressed on cells, domain ii of perlecan binds and internalises ldl in a similar manner to lrp (fuki et al., ). the development of perlecan gene knock-out mice has demonstrated the essential role played by perlecan in cartilage development and skeletogenesis. homozygous knockout mice, which survive to birth, display severe skeletal defects with short axial and limb bones, defects of vertebral ossification centres, cleft palate, and striking abnormalities in the growth- plates of their long-bones (arikawa-hirasawa et al., ). null mice for the proteoglycans prg and bgn have also been generated. biomechanical studies of prg knockout spines have revealed an increased torsional modulus, and disc dimension measurements suggest that null discs have a reduced transverse major diameter and height, with an np that takes up a relatively larger area of the disc (teeple et al., ). bgn is a slrp that contributes to collagen fibrillogenesis, control of the bioavailability of tgf-β activity, and cellular regulation. consequently, bgn knockout mice display premature osteoarthritis and early-onset disc degeneration involving both the af and np (furukawa et al., ). in addition to proteoglycans, collagens are major matrix constituents of the disc matrix. inactivation of col a leads to premature ossification and ivd degeneration. one-month-old col a (+/−) mice have shorter spines, thicker and irregular vertebral endplates that calcify prematurely, and lower gag levels in the af. by months, some compensation in these spinal changes occur (sahlman et al., ). homozygous transgenic mice lacking col a die at birth and show severe skeletal defects characterised by impaired endochondral ossification and an inability to pattern the notochord during disc development (aszódi et al., ). collagen ix is a nonfibrillar collagen composed of three gene products: alpha- (ix), alpha- (ix), and alpha- (ix). collagen ix molecules are localised on the surface of type ii-containing fibrils and consist of two arms. these include a long arm that is crosslinked to collagen ii and a short arm that projects into the perifibrillar space (diab et al., ). it has been proposed that collagen ix molecules are involved in the interaction of fibrils with each other or with other components of the ecm. a mouse lacking both isoforms of the alpha- (ix) chain has been developed (col a null). col a null mice do not show evident abnormalities at birth, but progressively develop marked joint degeneration as is seen in osteoarthritis. col a null mice also develop premature degeneration associated with physical impairment and degenerative changes in the disc, including the ceps. behavioural studies measuring reflexes, beam walking, pole climbing, wire-hanging, grip strength, sensorimotor skills, and mechanical and thermal pain sensitivity were all compromised in these knockout mice (allen et al., ; boyd et al., ; goldring, ). interestingly, while preventing aggrecan turnover in murine tissues does not result in major phenotypes, blocking collagen turnover in some mouse models can have severe effects on skeletogenesis (glasson et al., ; holmbeck et al., ; little et al., ). mouse strains deficient in mmp- , - , - , - , - , - , and - have been developed (bian et al., ; foley and kuliopulos, ; van hove et al., ; kato et al., ; robinson et al., ; wells et al., ; wilson et al., ). while some changes in haematopoiesis and angiogenesis associated with the maturation of long bone growth plates have been reported in some of these models, little or no impairment in skeletal development has been observed. the contributions of individual enzymes and functional overlap with other mmps is therefore important to take into consideration. in contrast, membrane type- mt -mmp (aka mmp- ) knockout mice display cervical kyphosis, disc degeneration, and accelerated age-dependent osteoarthritic changes in the axial skeleton. this is apparently due to inadequate collagen turnover, which emphasises the critical role mt -mmp plays in the conversion of mmps from their inactive precursors into their active forms to promote collagenolysis in-situ (holmbeck et al., ). likewise, mmp efficiently cleaves collagen ii. mmp knockout mice display significant accumulation of interstitial collagen in their growth j melrose et al. murine spine models www.ecmjournal.org plate cartilages and delayed endochondral ossification due to inefficient collagen turnover (inada et al., ; stickens et al., ). its abundant presence in severely degenerated discs also highlights the deleterious role mmp can play in pathological states. matricellular proteins have emerged as important regulators of cell-ecm interactions and a growing body of evidence has established roles for these proteins in disc homeostasis. sparc is a matricellular protein important in the maintenance of ivd integrity. radiological examination of spines from -month-old sparc knockout mice revealed wedging, endplate calcification, and sclerosis. at months onwards, sparc knockout mice showed elevated cell numbers in the af and a greater incidence of af herniations. aged sparc knockout mice mirrored aspects of low back pain as they displayed changes in cutaneous sensitivity to cold, heat, mechanical stimuli, and ambulation, indicating pain may be emanating from the disc (gruber et al., ; millecamps et al., ). similarly, mice with disruption of the gene encoding thrombospondin- , a multifunctional, anti-angiogenic matricellular protein, showed impaired collagen fibrillogenesis, reduced levels of the intermolecular cross-linking enzyme transglutaminase, fragile skin, and disorganisation of annular lamellae (gruber et al., ). ectopic calcification is a notable feature that is known to occur in several spinal disorders. mice lacking ent , a model of diffuse idiopathic skeletal hyperostosis, show reduced expression of ank, enpp , and alpl in discs, increased af cell proliferation, and progressive ectopic calcification of fibrous connective tissues along the spine (warraich et al., ). analyses of af tissue isolated from ent knockout mice has further revealed that the observed increased cell proliferation is associated with an upregulation of e f transcription factors, the cell cycle regulators rb and cdk , and stimulation of the jnk/mapk pathway (veras et al., ). notably, the importance of genetic background in the ectopic calcification process has been recently demonstrated by the study of lg/j inbred mice, which show an age- dependent increase in dystrophic mineralisation of discs (this mouse strain will be discussed later in the review) (novais et al., ). an evolving view of inflammation in disc degeneration an association between increased inflammation and ivd degeneration is well-described and most commonly attributed to the cytokines tnfα and il- β. nevertheless, investigations of human tnfα overexpressing mice (tg and htnfαtg) and il- α/β double knockout (il- ko) mice have led to questioning the understanding of the role inflammation plays in disc homeostasis. while polyarthritic tg-htnf mice show compromised vertebral bone parameters, af defects, and a greater propensity for herniations at the cep/ af junction, the presence of increased tnf-α in these mice did not show adverse effects on the np compartment. surprisingly, tg-tnf mice showed healthy-appearing np cells that assembled into an expanded cell band and the overall transcriptomic profile remained unaltered (gorth et al., ; gorth et al., ). this phenotype contradicts the existing view that chronic tnfα overexpression would cause pronounced disc degeneration, as the articular joints of these mice are severely degenerated by rheumatoid arthritis. plausible reasons for this phenotype could be that previous studies have exclusively used herniated human disc material with infiltrated immune cells as starting material for the analysis, shaping the understanding of the function of tnfα in the disc compartment. this phenomenon, in which differential effects of inflammation are observed in discs as opposed to articular cartilage, has also been noted in tonebp haploinsufficient mice. tonebp- deficient np cells downregulate pro-inflammatory molecules yet experience notable degeneration, while, on the other hand, tonebp-deficiency is protective against immune-driven arthritis (tessier et al., b). the differential effects of inflammation on these joints may be credited to the fact that the inner disc is largely avascular and immune privileged, unless penetrated by herniation. similarly, while conditional loss of p ink a (acancreert ; p ink af/f) shows lower np levels of il- β, il- , and mcp- , these mice are not protected from age-dependent degenerative changes (novais et al., ). global il- α/β double knockout mice also show higher degenerative grades with aging than wild-type counterparts, suggesting that loss of il- does not serve a protective role (gorth et al., ). seemingly contrary to the phenotype of these il- knockout mice, mice null for the il- rn gene were reported to develop spinal abnormalities (phillips et al., ). however, the discrepancies in these findings may be reflective of mouse strain-dependent effects (c bl/ , il- ko; balb/c, il- rnko), highlighting the complexity of inflammation on disc health. the cytoskeleton the cytoskeleton is fundamental to cell biology as it maintains intracellular organisation and cell shape, offers mechanical support, and links the cell to extracellular components by transmembrane proteins to enable functions such as cell adhesion and migration. although this critical component of the cell is largely understudied in ivd tissues, a few mouse models targeting the cytoskeleton have been developed. these include mice lacking arp / , the branched actin nucleator, and flnb, an actin-binding protein which forms a linking scaffold to coordinate signal transduction (table ). constitutive deletion of the arpc gene encoding a critical subunit of the arp / complex in collagen ii-expressing cells (col a -cre; arpc fl/fl) results in severe chondrodysplasia and spinal defects. these mice are dwarfed due to disorganised growth plates, present with kyphosis, and show dramatic changes to the ivds, some of which are fused. on histology, www.ecmjournal.org j melrose et al. murine spine models the growth plates are grossly expanded, the np is reduced in size, and the af is deformed and disorganised, containing rounded chondrocyte-like cells. embryonic and postnatal lethality in these mice led to the crossing of arpc f/fl with the inducible acan- creert allele to generate acan-creert ; arpc f/fl mice. resultant loss of arp / at skeletal maturity was shown to induce notable af degeneration marked by altered matrix composition. in vitro analyses further revealed that arp / controls tonebp-dependent osmoadaptation and cell-ecm interactions in np cells (tessier et al., a). similarly, the discs of flnb−/− mice show rapid and progressive degeneration during postnatal development. the af cells of these mice undergo differentiation into the chondrogenic lineage, acquiring the signature of hypertrophic chondrocytes and upregulating tgfβ and bmp signalling. consequently, af tissues show endochondral- like ossification, express collagen x, and evidence increased apoptosis, leading to vertebral fusions (zieba et al., ). loss-of-function of other factors known to influence the cytoskeleton such as n-cadherin and αvβ integrin have also been investigated in mice and are associated with altered disc cell morphology and degenerative phenotypes (bian et al., ; hwang et al., ). nuclear hs-proteoglycans such as perlecan have recently been identified in np cells. these may interact with cytoskeletal components and re- organise the nucleosome and chromatin organisation which may regulate the access of transcription factors to dna (hayes and melrose, ; kovalszky et al., ). nuclear hs-proteoglycans inhibit histone deacetylases resulting in chromatin compaction affecting dna accessibility to transcription factors. hs also inhibits dna topoisomerase i activity, which has important roles to play in ( ) the removal of dna supercoils during transcription and dna replication; ( ) the re-annealing of dna strands following strand breakage during re-combination and chromosomal condensation; and ( ) the disentanglement of intertwined dna strands during mitosis (champoux, ; wang, ). nuclear heparanase may have roles in the regulation of nuclear hs-proteoglycans (chen and sanderson, ). insights from inbred mice while genetically modified mice have offered important insights into the function of individual genes, recent investigations of inbred mouse strains (sm/j, lg/j, and c bl/ ) have provided invaluable lessons on the pathogenesis of disc degeneration. sm/j (small) and lg/j (large) mice, generated by crossing multiple inbred strains and selecting for body size, are models of choice for qtl analysis. these strains show differential cartilage healing capacities: sm/j is considered a poor healer strain whereas lg/j is considered a super healer. the sm/j is the first mouse model to show early onset and spontaneous disc degeneration without the need of overt, inflammation-causing injury such as annular puncture, tail looping, or mechanical overloading (choi et al., b; zhang et al., ). thus, the sm/j is proposed to more closely resemble the chronic disc degeneration seen in most humans. the disc phenotype of these mice has been characterised by matrix fibrosis, elevated markers of hypertrophic chondrocytes, increased np cell death, decreased wnt and vegf signalling, and dysregulated ion transport systems (choi et al., b; zhang et al., ). an extensive characterisation and comparison of these inbred mice, as well as the commonly used c bl/ j strain, during the aging process has been recently conducted by novais et al. ( ). an important insight derived from these studies is the observation that each mouse strain possesses a unique disc degeneration phenotype, with dissimilar morphological features, transcriptomic signatures, and onset of disease. strain-dependent differences at the gene expression and histological level following traumatic injury have also been recently demonstrated (brent et al., ). ultimately, these differences underscore the notion that disc degeneration is largely influenced by genetic background and therefore, when combined with environmental and mechanical factors, presents heterogeneously across individuals as sub-phenotypes. conclusions with the advances in knowledge provided by the completion of the human genome project and elucidation of the complete murine genome, the mouse represents the vehicle of choice for further examining the role of specific human gene abnormalities on spinal development and homeostasis in health and disease. while the mouse musculoskeletal system displays notable differences, including the persistence of notochordal-np cells, quadrupedalism, additional vertebrae, and some variations in the structure of proteoglycans, the mouse model nevertheless is an attractive experimental system to answer important questions in spinal pathobiology. due to these intrinsic differences, careful interpretation of experimental findings is indicated when attempting to make comparisons with the human musculoskeletal system. the described studies on the mouse ivd have identified many potential therapeutic targets worthy of further model phenotype references col a -cre; arpc fl/fl severe chondrodysplasia, spinal defects, dwarfism, growth plate expansion, deformation of af and np compartments, fused discs. tessier et al., a acan-creert ; arpc f/fl np cell-band expansion and af degeneration marked by altered matrix composition. tessier et al., a flnb knockout postnatal progressive disc degeneration, endochondral-like ossification of af, vertebral fusions. zieba et al., ta b l e . m o u s e m o d e l s w i t h m u t a t i o n s i n cytoskeleton genes. j melrose et al. murine spine models www.ecmjournal.org examination, not only in the mouse, but also in other animal models, to ultimately identify their roles in human disc degeneration. acknowledgements this study is supported by the grants from the national institute of arthritis and musculoskeletal and skin diseases (niams) r ar , r ar , and r ar . references abreu jg, ketpura ni, reversade b, de robertis em ( ) connective-tissue growth factor (ctgf) modulates cell signalling by bmp and tgf-β. nat cell biol : -

( ) - ; fax ( ) - . book reviews there is a statistically-based portrait, but the author's findings are largely negative. the group was older (a natural consequence of their training and careers before politics) and initially they were more likely to identify with political parties of the left, until the whole character of the legislature itself shifted in that direction by the end of the century. but for the most part, the physician-legislators were more the representatives of their local constituencies than of their profession. this was especially the case with questions of food and drink regulation, health insurance, or industrial hygiene and housing which doctors usually viewed more from the perspective of local economic interests than that of health professionals. to emphasize the exceptions to this rule, the author concludes with an examination of medical and health related legislation that the doctors generally supported. utilizing the work of jacques leonard and margaret hildreth to establish the setting, he makes his case that the physicians in parliament not only supported but also played an important role in shaping such legislation as the law on the practice of medicine and the public health law. the faults of the book are few. methodologically, the author could have been more rigorous in his collective description of the physician-legislators to show which characteristics were typical of all legislators as opposed to just those who were doctors. also, the descriptions of the legislative campaigns sometimes read like a chronological list of bills presented, which only touch the surface of complex movements (tuberculosis, mental illness, etc.) whose main thrust lay outside parliament. finally, to those who might ask whether the main question posed by the author warrants a whole book to answer it, it must be admitted that the topic may be a relatively small niche in the history of modern medicine and politics, but the author fills it well. william h. schneider, indiana university carol trowbridge, andrew taylor still, - , kirksville, missouri, the thomas jefferson university press, , pp. xiv, , illus., $ . ( - - -x). biographies of the "founding fathers" of "the fringe" are typically more hagiographic than historical, more celebratory than critical. although the publication of this biography of the inventor of osteopathy has been timed to coincide with the th anniversary of the founding of the first school of osteopathy, in kirksville, missouri, the author manages to avoid the deification of her subject. instead, she provides an understanding of the world that shaped his thinking. drawing effectively on recent work in the history of popular science and medicine, as well as on the local history of society, politics and religion in the "bled" frontier states of kansas and missouri, carol trowbridge illuminates how still's peculiar therapeutic achievement was fully a product of its phrenological, mesmeric, thomsonian, eclectic, spiritualist and, above all, spencerian evolutionary times. on the whole, trowbridge is far more successful at elaborating the mind of still, than at accomplishing her book's other main mission, to fill in the narrative gaps left in still's autobiography of . particularly in relation to the practical realization of osteopathy, trowbridge fails to deliver the "new and important facts" promised on her dust-jacket. on the seemingly central question of how still came by his practice of bone-setting, for example, trowbridge has regrettably little to say-less in fact than norman gevitz in his much broader history of osteopathy. it seems a pity that in a study of this kind the opportunity was not seized to inquire into either the local or the national practice of bone-setting during the s and s when still was advertising himself as the "lightning bone setter". nor is it made clear why still's popularity should have "surged" at this point through this conceit. some attempt at a systematic study of the "hundreds of patients [who] now awaited still's arrival in various towns" (p. ) would not have come amiss. one is left still wondering how the cognitive and therapeutic worlds actually folded together in the invention of osteopathy. roger cooter, wellcome unit for the history of medicine, manchester available at https://www.cambridge.org/core/terms. https://doi.org/ . /s downloaded from https://www.cambridge.org/core. carnegie mellon university, on apr at : : , subject to the cambridge core terms of use, https://www.cambridge.org/core/terms https://doi.org/ . /s https://www.cambridge.org/core review began / / review ended / / published / / © copyright zavodnick et al. this is an open access article distributed under the terms of the creative commons attribution license cc-by . ., which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. effect of a female external urinary catheter on incidence of catheter-associated urinary tract infection jillian zavodnick , caitlin harley , kelly zabriskie , yasmin brahmbhatt . department of internal medicine, thomas jefferson university, philadelphia, usa . department of nursing, thomas jefferson university, philadelphia, usa . department of infection control, thomas jefferson university, philadelphia, usa corresponding author: jillian zavodnick, jillian.zavodnick@jefferson.edu abstract background catheter-associated urinary tract infections (cautis) can be fatal, and are a source of avoidable expense for patients and hospitals. prolonged catheterization increases infection risk, and avoiding catheters is crucial for infection prevention. male external urinary catheters are recommended as a tool to prevent the need for indwelling catheterization. female external urinary catheters (feucs) have intermittently been marketed without wide adoption; one has recently become available but published data is limited. objective this retrospective observational study was conducted to investigate the effect of feucs on indwelling catheter use and female cautis. methods feucs were introduced to intensive care units. cauti rates and indwelling catheter days were obtained before and after the introduction of the devices. results cauti rates decreased from . per catheter days to . per catheter days (p= . ). female indwelling catheter days decreased, while overall intensive care patient days increased. conclusions introduction of a feuc was associated with a statistically significant decrease in cauti rate among female intensive care patients. the feuc may prevent the need for indwelling catheters in some situations. categories: internal medicine, infectious disease, quality improvement keywords: hospital acquired infection, cauti, external urinary catheter, female external urinary catheter, cauti prevention, infection control, nosocomial infection introduction indwelling urinary catheters (iuc) are commonly used in hospitals, and have a number of potential complications including catheter-associated urinary tract infections (cautis) [ ]. cautis increase mortality, length of stay, and costs, with the cost of a single cauti recently estimated to be over $ , for a patient in intensive care; prevention is therefore a major focus for hospitals [ - ]. longer duration of indwelling catheterization increases cauti risk, and avoidance of iucs when feasible is an important part of cauti prevention [ ]. educating hospital staff on the benefits of iuc avoidance and removal [ ], as well as restricting iuc use and increasing access to alternatives to catheterization, have been well-studied methods for decreasing cautis [ , ]. male external urinary catheters have long been available, and are recommended by multiple society guidelines and as part of a published preventive bundle to decrease cautis [ , - ]. female external urinary catheters (feucs) have intermittently been marketed but never widely adopted [ , - ]. the purewick feuc (bard and purewick, becton, dickinson and company, franklin lakes, new jersey) has recently become available, but published data is so far limited to a single case series without systematic outcomes, a limited local investigation showing a decrease in iuc utilization after implementation without a decrease in cauti, and one inpatient study demonstrating an initial decrease in cauti which was not sustained after one year [ , - ]. cauti rates at our institution decreased over the past ten years with the introduction of new prevention measures (e.g. nurse-driven catheter removal protocol), but then reached a plateau once these measures had open access original article doi: . /cureus. how to cite this article zavodnick j, harley c, zabriskie k, et al.

https://www.cureus.com/users/ -caitlin-harley https://www.cureus.com/users/ -kelly-zabriskie https://www.cureus.com/users/ -yasmin-brahmbhatt been consistently adopted. we began performing root cause analysis on all cautis to determine factors leading to the infection, with a goal of targeting future interventions to further decrease cautis. among other findings, we recently learned that the majority of iucs were placed for the purpose of close monitoring of urine output. we hypothesized that the introduction of an feuc would decrease utilization of iucs, and that this would prevent cautis. as our outcome measure, we compared cauti rates in female icu patients before and after the product became available. we measured catheter days in female icu patients as a process measure, hypothesizing that feuc availability would decrease iuc use as the mechanism of decreasing cauti. materials and methods setting thomas jefferson university hospital (tjuh) is a large urban academic medical center closely associated with jefferson hospital for neuroscience (jhn); these hospitals report jointly for some measures. together these hospitals contain nine intensive care units. the hospitals have long had a nurse-driven iuc protocol enabling removal without a physician order when patients no longer meet criteria for iuc use, a practice shown to decrease cauti [ ]. jefferson’s standardized infection ratio, a measure of cauti prevalence, was . in the year prior to this study. study design we performed a retrospective observational study. participants included all adult icu patients from january , to december , , a total of , patient days. as our main outcome, we compared cauti rates in female icu patients in the year before (jan , to december , ) and the two years after (jan , to december , ) the feuc became available at our hospital using the national healthcare safety network (nshn) measure of cauti per , catheter days [ ]. when calculating cauti rates, iuc days, and hospital-acquired pressure injury (hapi) rates, male patients were excluded. the hypothesized mechanism for decreased cauti after feuc introduction was decreased iuc use. to confirm this, we examined iuc days in female patients, calculated as a count of the number of female patients with iuc presence charted by the nurse each day of the study period. a decrease in iuc days with the introduction of the feuc would suggest the avoidance of iuc use, while no decrease would suggest that the feuc was being adopted primarily in patients who would not have had an iuc. hapi was analyzed in the same population over the same time frame as a secondary outcome and balancing measure. the measure was defined as a pressure-induced mucosal injury, non-mucosal ulcer of stage one through four, unstageable ulcer, or deep tissue injury [ ]. if the pressure injury was related to a medical device, this was recorded as well. the adoption of the feuc for patients with moisture dermatitis or at risk of skin breakdown was not anticipated to decrease cauti rates as these patients would not otherwise have had iucs, but might be expected to decrease hapis, making hapi a useful secondary outcome. however, since our hapi data includes device-related pressure injuries, an increase in device-related hapi with the introduction of an feuc could be evidence of unintended consequences of device adoption. we did not measure moisture dermatitis rates directly. we were not able to directly measure feuc days or how many patients had an feuc placed. information on icu patient days was collected to control for the impact of patient volume on iuc days; information on female-only icu days was not available, so male and female patients are included in this measure. cauti data was obtained by infection control personnel from an epic data report of positive urine cultures, which infection control staff used to determine whether cauti criteria were met. it was then analyzed using the nhsn data reporting tool and microsoft excel. hapi data was obtained by staff nurses trained as “skin champions” during a monthly assessment of all icu patients, and was analyzed using microsoft excel and spss. the two-sided fisher’s exact test was used to determine statistical significance. intervention the purewick feuc was introduced to all icus in january of . the product consists of a urine

feuc is in place. the decision to use the feuc in a given patient was nursing-driven, with guidelines given for appropriate indications. the first indication was patients requiring strict monitoring of intake and output without other means of obtaining these measurements; using the feuc for this indication was anticipated to avoid the need for an indwelling catheter. the second indication was moisture dermatitis or potential for skin breakdown due to incontinence; this is not an indication for an indwelling catheter at our institution, although inappropriate use of catheters for this indication has been described [ ]. using an feuc for this indication was intended to decrease pressure injuries, and was not expected to decrease iuc use or cauti. the introduction was overseen by the cauti working group, an interprofessional hospital committee with joint nursing and physician leadership, and representation from infection control professionals. representatives from the manufacturer trained all icu nurses in the use of the product. a few nurse members for each unit underwent more in-depth training so that they could serve as “superusers” to continuously educate other staff. product representatives remained available for questions as nurses began using the feuc. the thomas jefferson university institutional review board categorized this intervention as work not zavodnick

became available, iuc days decreased among female icu patients, even though the number of icu patient days increased overall. the decrease in iuc days alongside the increase in icu days suggests that there may be some adoption of the feuc in place of iucs for strict intake and output monitoring, a trend which would be expected to decrease cauti rates, and has been demonstrated in recently presented data [ ]. zavodnick et al. cureus ( ): e . doi . /cureus. of data on skin outcomes does not suggest that pressure injuries are being avoided through use of the feuc. we propose the measurement of skin outcomes during the introduction of this device for two purposes. first, this can serve as a secondary outcome measure for the use of a feuc in cases of incontinence alone without an indication for an iuc. second, device-related pressure injuries could be a useful balancing measure, demonstrating unintended consequences of feuc adoption. however, hapi is a heterogeneous and multifactorial measure and there are multiple variables besides feuc adoption which may have led to our increased rates. many patients at risk for hapi have no indication for an external or internal urinary catheter, and we expected that any effect of this product on hapi would be modest at best. hapi data collection does include device-associated pressure injuries, which are a useful balancing measure for feuc use; these did not significantly change during the intervention period. ongoing careful surveillance will be needed to ensure that the feuc is not associated with increased device-associated pressure injuries. informal feedback from patients and nursing has been positive, and prior to the availability of outcomes data, the product had been introduced to all units of the hospital. this was done at the request of non-icu nurses who were aware of the product, and after feedback from patients who had used the feuc while in the icu and were frustrated at the need to discontinue it when transferred to the floors. even before a statistically significant decrease in cauti rates was demonstrated, staff and patient feedback led the hospital to continue making the feuc available. there are some limitations to our analysis. we were not able to obtain specific data on feuc utilization. for the primary outcome of cauti, we used the process measure of iuc utilization as a proxy for feuc use. however, there could be other factors leading to the decrease in iuc use during this time frame. we also noted an increase in icu days for all patients alongside a trend toward fewer cautis in female icu patients, the only population expected to be affected by the availability of an feuc. from this we inferred that the decrease in iuc use was not driven purely by lower patient volumes. this inference depends on two assumptions: first, that female icu days did not decrease relative to male icu days over this time period; and second, that there was no difference in the number of patients with a potential iuc indication between the before and after periods. these assumptions are reasonable but cannot be demonstrated by our data. there are also significant limitations pertaining to skin outcomes. moisture-associated dermatitis would have been a useful outcome to directly track the effectiveness of the feuc when used for the indication of skin protection, but was not available. the use of hapi as a proxy measure ignores patients who might have moisture-associated dermatitis that does not progress to a pressure injury. data collection for hapi comes from monthly prevalence surveys and may underestimate device-associated pressure injury, which is an infrequent occurrence. this data is unable to distinguish between types of devices leading to pressure injury; pressure injuries resulting from tracheostomy devices, for example, would be unaffected by our intervention. hapi assessment was not performed in december of , which is expected to artificially lower the total number of hapi in the post-intervention period (monthly average and prevalence should remain unaffected). although we recommend that institutions adopting the feuc make an effort to measure skin outcomes, our hapi measurement procedures significantly limit this measure’s use for the purpose of evaluating this device. an feuc is a feasible, well-tolerated intervention that is associated with decreased iuc utilization and cauti rates. further study is needed with direct tracking of feuc utilization by indication, and with measurement of moisture dermatitis. a cost-benefit analysis would be useful in determining the total utility of this product. further investigation could consider the incorporation of the population cauti rate, cauti per , patient days, a measure proposed as an alternative to the nhsn definition in a low-prevalence environment [ ]. conclusions the number of iuc days decreased with the availability of the feuc despite a slight increase in patient days, suggesting that this product may prevent the need for iuc in some situations. there was a statistically significant decrease in cauti rate, a meaningful outcome which also further supports the conclusion that iuc use decreased. no change was noted in hapi, but this analysis was subject to significant limitations. further quality improvement initiatives that focus on female iuc, hapi and cauti rates with the feuc product are warranted. additional information disclosures human subjects: consent was obtained by all participants in this study. thomas jefferson

demand for th and prepare them for diverse job opportunities. categories: medical education, emergency medicine, healthcare technology keywords: telehealth, telemedicine, graduate medical education, training, professional development introduction telehealth (th) has been shown to broaden access to healthcare [ ], increase efficiency while reducing costs [ - ], and enhance patient satisfaction and health outcomes. given its rapid expansion, there is an emerging need for trained professionals who will effectively deliver th services. more recently, th has been used as a direct connection to the patient, rather than a physician to physician consult. the direct-to-consumer th industry is growing rapidly with over million visits in [ ]. international healthcare organizations, practitioners, patients, families, policy makers, and legislators are increasingly recognizing the value added by the integrated use of telehealth. given the high impact potential of telehealth, it is predicted that there will be an . % annual growth of th services through , inevitably resulting in spiking demand for th training and coordination [ ]. the health report states that the introduction of new th and telemonitoring programs in healthcare will require a new subset of skills that will change the roles and responsibilities of health providers [ ]. to date, there are few academic programs that offer th training especially for post-graduate resident trainees [ ]. the university of alaska southeast (in partnership with alaska federal health care access network) is one of the few institutions in the country that offers a th certificate program (for continuing education, ce, contact hours). the university of arizona, university of california-davis health system, and waldo county general hospital (maine) also run similar programs. other non-accredited, short-term training and educational resources exist, most notably through the cal telehealth resource center (also for ce credit) and the american telehealth association (ata). there are no sizeable general th programs in the northeast united states [ ]. given telehealth’s growing market and trending demands in the united states and abroad, it is expected there will be significant implications and expectations for the emergency medicine (em) residency graduate. it was in response to this accumulating evidence that the department of emergency medicine (dem) at thomas jefferson university (tju) created and successfully integrated a th training program into its residency program in an effort of preparing its graduates for telehealth’s rapidly-growing demand. a major focus was placed on developing senior residents’ clinical and non-clinical skills that are essential to th delivery, such as the th physical exam, virtual doctor-patient communication, and troubleshooting technological challenges. the goal of this paper is to describe the first months of the program, including the resident and patient experience of a novel th follow-up encounter subsequent to the traditional ed visit. specifically, the authors aimed to determine if such a training program could be integrated into an em graduate medical education program to describe what patient complaints em residents would typically encounter through a th medium, and to survey residents on the educational value of th training. papanagnou et al. cureus ( ): e . doi . /cureus. of materials and methods our curriculum and quality improvement project was completed at tju, an academic medical center located in philadelphia, pennsylvania that has an enterprise-wide telehealth program (jeffconnect) including / / on-demand access to an emergency physician, a -hospital neurostroke network providing partner affiliate hospitals’ emergency physicians with telehealth access to neurovascular experts, and scheduled visit programs in clinical specialties. over , telehealth calls are completed annually. targeted learners the tju sponsors a -year (post-graduate year, pgy, through ), em residency training program, with total residents ( residents per year). the residency program is accredited by the accreditation council for graduate medical education (acgme). during the one-month emergency medicine administration and teaching (emat) block of the last year of training, pgy- residents were immersed in a multifaceted th experience which exposed, educated, and trained senior residents on the delivery and utility of telehealth in patient care. with regards to the goals of the rotation, residents were expected to develop both the clinical and non-clinical skills that are essential to telehealth care delivery, such as the th physical exam, virtual doctor-patient communication, and troubleshooting technological challenges. at the beginning of the rotation, residents were given an introductory orientation providing them with an overview of the th program. residents were provided with resources on telehealth principles. these resources included internally-developed modules that introduced telehealth, its applications, the telehealth physical exam, troubleshooting, and regulatory considerations; institution-specific clinical pathways; and video examples of successful th encounters. residents spent four hours per week performing follow-up visits on patients seen in the ed within the past five to seven days. ed patients appropriately identified for a follow-up visit were given a specific day and time for their virtual telehealth encounter, which was facilitated by the pgy- resident, and supervised by a faculty member credentialed in telehealth delivery. patient recruitment ed patients suitable for a telehealth follow-up visit were identified by a faculty member, resident, and/or research coordinator. patients were enlisted for a th follow-up visit only if the treating physician agreed that a timely follow-up visit would be helpful for the patient and would assist in the management of his/her chief complaint. chief complaints were low-acuity, and included upper respiratory infections, wound care concerns, lacerations, cellulitis, headaches, or minor trauma, as examples. if an ed patient was amenable to participate in a virtual visit, a research coordinator then scheduled the patient for the virtual appointment prior to his/her discharge. all patients were also contacted days after their th visit to assess whether their respective issues were resolved or further care was necessary, and to gauge their experience with the th encounter. assessment and supervision each resident was expected to complete hours of directly supervised th delivery over the four-week period ( hours per week x four weeks). evaluations of residents were performed by the supervising faculty member. all supervising faculty members hold a faculty appointment in the dem are trained in th and provide ongoing th coverage within the enterprise-wide jeffconnect program. formative feedback was provided to each resident during and at the completion of each th encounter. papanagnou et al. cureus ( ): e . doi . /cureus. of the telehealth visit prior to the th encounter, residents reviewed the patient’s ed note from their original visit to the hospital. all scheduled visits were conducted via video using a hipaa-compliant, secure, jeffconnect platform (www.jeffconnect.org), which can be conducted via the web, smart phone, or tablet device. at the time of scheduling, a coupon code was created, which made the follow- up visit free to the patient. when logging-on to the platform, patients entered structured clinical information, including any medications and allergies. once this information was successfully entered, patients clicked a button that immediately connected them to the physician. the average wait time for this process is one to three minutes. physicians and patients were then able to view one other, similar to a video call on skype or facetime. documentation was captured in the electronic medical record, identifying the encounter as a th visit, and linking it to the original ed visit as an addendum to the patient's medical record. data collection during the telehealth encounter, residents followed a standardized approach to collecting patient data, which included medication reconciliation, assessment of whether ed discharge follow-up instructions were followed, and an assessment of how the patient was doing since his/her discharge from the ed. any issues or questions that patients had were also addressed. data collected from each encounter included the number of patient visits to the ed, chief complaint, days between initial visit and telehealth visit, and an assessment of medication and discharge instruction compliance. patients who received a telehealth visit were sent a brief follow-up survey at days, which asked them ) how helpful the th visit was, ) if they would recommend a th follow-up to someone else, and ) if they required additional care since their ed visit (i.e., an additional ed or urgent care visit and/or hospitalization). at the end of the rotation, all pgy- residents completed a short survey, administered through survey monkey, which solicited feedback on the educational value of the th experience. open-ended questions were included in the survey to capture resident comments on the benefits of th training, ways in which the experience could be enriched, and residents' opinions on whether th training should be included in the formal em residency curriculum. data are presented as descriptive statistics. because of its focus on quality improvement, the study was exempt from review by the institutional review board (irb) of the sidney kimmel medical college of tju. educational and theoretical considerations the educational framework that informed the telehealth training program is rooted in experiential learning; furthermore, resident supervision by telehealth-trained faculty preceptors promoted reflection after telehealth clinical encounters. david kolb’s widely quoted ‘experiential learning cycle’ informed training program design. kolb originally represented four elements (i.e., concrete experience, observation and reflection, the formation of abstract concepts, and active experimentation) in an experiential learning circle that provides a flexible framework for instructional design [ ]. the model is derived from a model of social learning that connects variability of individual learning style to flexibility in learning context [ ]. in the context of the telehealth encounter, the senior resident is immersed in a concrete experience (i.e., the jeffconnect telehealth patient encounter), he/she then observes and reflects on himself/herself or others (i.e., debriefing with the faculty preceptor and/or observation of ‘modeled’ encounters by the faculty preceptor), the learner is then able to make inductive systematic conclusions or abstractions (i.e., refining frames for his/her clinical practice via the telehealth medium), which then allows the learner to empirically test the action plans that arise from the abstract concepts (i.e., applying this

], providers will need to have standardized training to teach how to appropriately and effectively provide these services. papanagnou et al. cureus ( ): e . doi . /cureus. of this is the first report of an integrated th curriculum within an em residency program. specific objectives of our program included the following: . introduce resident physicians to a professional ‘tele-presence,’ including appropriate attire, technological preparation, and environmental preparation. . develop the skills needed to effectively conduct th visits (i.e., camera positioning, eye contact, and documentation). . conduct appropriate histories and physical exams within the scope of th, under the supervision and guidance of a trained faculty member. . apply and critique peer-reviewed clinical pathways for th delivery for common patient complaints. . systematically troubleshoot computer and connectivity issues, and . educate patients on the utility and limitations of th. in this novel educational program, our first class of graduating pgy- residents successfully met these objectives through ‘on-the-job’ training and direct supervision from em faculty who were trained in th delivery. most residents agreed that th should be incorporated into the em curriculum, to some capacity. comments made by residents were also insightful, and highlighted areas where improvements could be easily made to maximize the educational value of the th experience, including better utilization of downtime. the healthcare sector has acknowledged the increasing value added by the integrated use of th [ - ]. its benefits are threefold: this new means of healthcare delivery has the potential to significantly broaden access to healthcare, increase efficiencies and reduce costs, and enhance patient safety, quality of care, and ultimately, patient outcomes. there are several limitations worth noting in our study. the sample size included in our training intervention was only limited to the pgy- cohort at our training site. future plans will aim to aggregate this data with yearly data of graduating senior residents working with th. if possible, there may be utility to compare and contrast the experience of em resident trainees with residents from other specialties and across other institutions. the authors also wish to acknowledge that the study was possible given the successful th program that currently exists at the host institution, to some extent, this may impact its reproducibility at other institutions. with regards to the overarching research question initially posed, our data supports that integrating th training into a graduate medical education program for senior em residents is quite feasible. in terms of program effectiveness, the kirkpatrick four-level training evaluation model was helpful to objectively analyze the impact of integrating th emergency department visits into residency training. trainees reacted well to training (level : reaction), the majority of residents enjoyed the program and agreed that it was of sound educational value. through successive th patient encounters, senior em residents were able to learn how to independently facilitate a supervised th encounter for a wide array of common patient presentations (level : learning) using specific skills to conduct the th visit and troubleshoot connectivity issues. senior residents were also able to apply their traditional patient care skills (i.e., extracting histories and conducting physical examinations) to the supervised th encounter (level : behavior). papanagnou et al. cureus ( ): e . doi . /cureus. of next steps for this program will include evaluating kirkpatrick’s level (results) on programmatic impact. specifically, the investigators plan to examine long-term outcomes on patients evaluated via th (i.e., hospitalization rates, patient satisfaction ratings). preliminary patient-specific data is encouraging: the majority of patients highly rated the th encounter, and the majority of patients would recommend a th visit to someone else. the investigators also plan to incorporate resident feedback into the th experience to further improve the training program’s impact. based on feedback provided, consideration will be made to expand the program to include first-time encounters of the undifferentiated patient via the th platform, and appropriately link learning outcomes to acgme milestones relevant to em. conclusions in response to the accumulating evidence in support of new th roles and education, we have created a feasible th training opportunity integrated within an em residency training that aligns with patient-centered care. in this first-year pilot program, both patients and resident providers were satisfied with this new service and new educational opportunity, respectively. successfully optimizing this rotation has the opportunity to create a unique training opportunity for em residents, which will help them become part of a skilled th workforce to meet a rapidly-growing demand, and, in the process, prepare them for diverse and future- oriented job opportunities. additional information disclosures human subjects: consent was obtained by all participants in this study. thomas jefferson university issued approval n/a. the study was exempt from review by the institutional review board (irb) of the sidney kimmel medical college of thomas jefferson university in philadelphia, pennsylvania, as it was part of a university-wide training program intervention for post-graduate trainees at our institution. no patient identifying information was collected. please note that the study did not involve animal or human tissue. . animal subjects: all authors have confirmed that this study did not involve animal subjects or tissue. conf licts of interest: in compliance with the icmje uniform disclosure form, all authors declare the following: payment/services info: all authors have declared that no financial support was received from any organization for the submitted work. financial relationships: all authors have declared that they have no financial relationships at present or within the previous three years with any organizations that might have an interest in the submitted work. other relationships: all authors have declared that there are no other relationships or activities that could appear to have influenced the submitted work. references . singh r, mathiassen l, stachura me, astapova ev: sustainable rural health innovation: a public health case study. health serv res. , : -

- , fax: - - . introduction the thz region, ( thz = cm- or mev), lies in the far infrared spectral range where conventional thermal sources are very weak. for example, a k blackbody source typically provides less than microwatt/cm- . while narrow band sources have been available using fel technology[ ], a significant advancement in broadband thz sources has occurred over the past decade with the advent of coherent thz radiation emission from photocarriers in a biased semiconductor or from optical rectification in an electro-optic crystal[ ]. an energy per pulse of about µj has been achieved, implying mw peak powers, but at repetition rates of khz such that average power levels are only mw[ ]. the jlab fel was used to produce such radiation from a semiconductor while operating in the third harmonic at micron[ ]. this work describes a different process for producing coherent thz radiation from accelerated electrons. this process also begins with pulsed laser excitation in gaas, but uses photoemission to produce bunches of electrons. using the energy recovery linac (erl) at the jefferson lab free electron laser[ ], electron bunches are brought to ~ mev in a linac and then transversely accelerated by a magnetic field to produce the thz emission as synchrotron radiation. this accelerator produces high average current (up to ma) by operating at a very high repetition rate (up to mhz) using superconducting rf cavities and recovering the energy of the spent electrons. electron bunches as short as ~ fs are produced by the technique of energy modulation followed by compression in the dispersive region of a magnetic chicane. like the thz emitter described above, the electrons experience a common acceleration. if the electron bunch dimensions are small (in particular, the bunch length is less than the wavelength of observation), one obtains a multiparticle coherent enhancement[ , ] of the form n[ - f(ω)]+n , where n is the number of particles in a bunch and f(ω)is the fourier transform of the normalized longitudinal particle distribution within the bunch. the power produced is given by larmor’s formula[ ] which in cgs units takes the form: e a power c γ= ( ) where e is the charge, a is the acceleration, c the speed of light and γ is the ratio of the mass of the electron to its rest mass. for a conventional auston switch thz emitter based on a laser pulse striking gaas, the voltage across the gap might produce an acceleration of the freed charges on the order of cm/sec . a similar acceleration results from a m radius magnetic bend but in our case γ is , yielding a considerable enhancement in radiated power. such coherent synchrotron radiation has been observed from electrons accelerated in linacs[ - ], and more recently it has been discussed and observed from electron bunches in storage rings[ - ], but not at thz frequencies or in a form stable enough for use as a light source although there are several development efforts in place in this area[ , ]. . calculations and results details of the theory have been presented elsewhere[ ]; in fig. we present calculations and measurements of the power emitted by a fsec fwhm electron bunch. we assumed the electron bunches had an energy of mev, a charge of pc, and that they passed through a m radius bend at a . mhz repetition rate. figure . calculated and measured spectral power. the measured spectrum suffers from diffraction losses at the long wavelength end. . . . . frequency (thz) measured calculated ( fs bunch length) w a tt s/ cm -

) the spectral content of the emitted thz light was analyzed using a nicolet rapid-scan michelson interferometer and detected using a . k infrared laboratories bolometer. our collection angle was × milliradians and the extraction window was quartz. we were able to determine the absolute power in two ways, one using a calibrated pyro- electric detector, and one by comparing our spectra with that from a k thermal source. the data has been scaled on the basis of these absolute power measurements. the spectral onset of the super- radiant enhancement of the thz light is clearly seen on the high frequency side. the onset shape is also seen to match closely the theoretical predictions. note that there is a severe discrepancy on the lower frequency side due to diffraction effects from the small aperture at long wavelengths. we note that we were able to observe considerable changes in spectral weight depending on operating conditions, and were able to enhance certain spectral regions via the machine parameters. thus the electron bunch distributions were not purely gaussian but contained higher order components. since we measured the intensity, not field, of the emitted light, we were unable to determine uniquely the electron density distributions, but this might be possible in future experiments using coherent detection. this can in principle be a powerful technique for the analysis of linac performance. for example noise spectral measurements (figure ) can be utilized to uncover sources of beam fluctuations. figure . a measurement of noise on the thz signal was used to identify fluctuations in the drive laser power on the cathode. finally we measured the polarization of the emitted thz light. the intensity ratio for the horizontal to vertical polarization components is for synchrotron radiation in the long-wavelength limit. this assumes full collection of the emitted radiation. we note that the dominant intensity is near cm- , which has a natural opening angle of millirad. since the emission pattern is “clipped” by the mrad collection optics, the calculated ratio is expected to be higher, approaching a value of . using a wire-grid polarizer placed between the michelson interferometer and the detector, we measured a ratio of (see figure ). figure . spectral characteristics illustrating the structure that can result from electron density modulation at higher orders than the bunch length. the measured polarization ratio is in agreement with calculations. the intensity of the radiation can be gauged from figure , which is a real time image taken in thz radiation on a pyroelectric camera. although detailed thz images have previously been obtained by a number of research groups, it typically took minutes to hours to obtain an image. the present source should permit real time imaging over large areas and/or determination of spectral absorption in a broad wavelength band simultaneously. -

). the importance of empathy as the foundation for positive relationships between patients and physicians has been discussed in medical edu- cation and health care research ( - ). physi- cian empathy and effective communication skills increase patients’ satisfaction, improve patients’ compliance, and enhance physicians ability to diagnose and treat their patients ( , ). improved outcomes may be a result of better compliance or the activation of psycho- logical factors that are formed in trusting rela- tionships ( , ). viewed from the contrasting perspective, a lack of empathy can have negative effects on clinical outcomes. resident’s humanistic qual- ities, communication skills, and professional- ism are considered important components of the trainee’s evaluation by both the american board of internal medicine, which certifies in- ternists, as well as the accreditation counsel for graduate medical education, which accredits programs in american medical schools(http:// www.acgme.org/outcome/comp/comphome.asp). while the new outcomes project of the ac- creditation counsel for graduate medical edu- cation does not specifically call for an evaluation of physician empathic concern; interpersonal communication with patients, cultural sensitiv- ity, and professionalism are key components of the new evaluation process. specifically, residents are expected to form effective therapeutic rela- tionships with patients and families, to build re- lationships through listening, narrative or non- verbal skills, and to develop skill in education and counseling of patients and their families (http:// www.acgme.org/outcome/comp/comphome.asp), all of which are relevant to physician-patient em- pathic engagement. patients are considered as an important source for the assessment of these skills. therefore, it is important to develop an in- strument to assess patient’s perceptions of phy- sician empathic engagement. this study was de- signed to examine the psychometric properties of such an instrument. methods participants data for this study were collected in and for internal medicine residents at dif- ferent levels of training at thomas jefferson uni- versity hospital and from patient encounters in the resident ambulatory clinic, jefferson hospi- tal ambulatory clinic. complete data (with no missing responses) were available for patient encounters with residents. instruments based on a review of literature, we developed the jefferson scale of patient’s perceptions of physician empathy. this is a brief instrument ( - item) intended to measure patient’s perceptions of his/her physician’s empathic concern and un- derstanding (table ). patients were asked to re- spond to each item on their physicians by using a -point likert-type scale (from = strongly dis- agree to = strongly agree). it takes a few min- utes to answer the scale. to examine the validity of the jefferson scale of patient’s perceptions of physician empathy we used the american board of internal medi- cine patient rating form intended to measure as- pects of physician communication skills, human- istic qualities, and professionalism in medicine ( ). this form was developed by the american board of internal medicine to be used as part of a comprehensive evaluation for physician recertifi- cation and presents an opportunity to assess phy- sician-patient relationships at all levels of medi- cal education and practice. the american board of internal medicine patient rating form used in this study included items, each answered on a -point likert scale (from = strongly disagree to = strongly agree). a “not applicable” option was also available. http://www.acgme.org/outcome/comp/comphome.asp http://www.acgme.org/outcome/comp/comphome.asp http://www.acgme.org/outcome/comp/comphome.asp http://www.acgme.org/outcome/comp/comphome.asp kane et al: patient’s perception of physician empathy also, five items that were conceptually rele- vant to empathic physician-patient engagement were selected to be used as additional criterion measures for the validity study (table ). four of these items were adapted from the physicians’ humanistic behavior questionnaire developed by weaver et al ( ), and one item was adapted from a questionnaire intended to measure pa- tients’ appraisal of physicians’ performance de- veloped by matthews and feinstein ( ). finally, we used scores of the jefferson scale of physician empathy that was administered to a sub-sample of residents to examine the concor- dance between patient’s perceptions of physician empathy and physician’s self-reported empathy. the jefferson scale of physician empathy is a - item scale with sound psychometric support that measures physician empathic orientation and be- havior ( - ). procedures the approval of our institutional review board was obtained for this project. patients were ap- proached in the waiting room upon checkout after completing their visit with their resident physician at the jefferson hospital ambulatory clinic. patients were asked by a trained research assistant to voluntarily and confidentially com- plete the survey containing demographic ques- tions, plus survey items ( for the jefferson scale of patient’s perceptions of physician empa- thy, criterion measures, and for the american board of internal medicine patient rating form) as a part of a quality improvement project with- in the residency program at thomas jefferson university hospital (web-extra material). the resident’s name was printed on the survey that was anonymously completed by the patient. to maintain complete confidentiality, the patients were guided to a private location, away from the physician treatment areas to complete the survey. the research assistant would offer to read and re- cord the patient’s responses if this was requested by patients. additionally, patients were told that their participation or refusal would in no way in- fluence the care they received. statistical analyses principal component factor analysis was used to examine the dimensionality of the jefferson scale of patient’s perceptions of physician empathy. we calculated the pearson product-moment cor- relation coefficients for the validity study. results a total of patient rating forms were received. of these, ( %) were complete with no missing data that were used as the units of anal- yses in this study. in factor analysis of data, only one factor emerged with an eigenvalue greater than one (eigenvalue = . ), indicating that the jefferson scale of patient’s perceptions of phy- sician empathy is a uni-dimensional scale mea- suring only one underlying factor interpreted as “empathic engagement.” the factor coefficients are reported in table . the item-total score correlations were all pos- itive and statistically significant (p< . ), and ranged from a low of . to a high of . with table . factor coefficients, item-total score correlations, and correlations with american board of internal medicine patient rating form for the items of jefferson scale of patient’s perception of physician empathy* items factor coefficients item-total score correlations correlations with abim patient rating form understands my emotions, feelings and concerns. . . . seems concerned about me and my family. . . . can view things from my perspective (see things as i see them). . . . asks about what is happening in my daily life. . . . is an understanding doctor. . . . *the jefferson scale of patient’s perceptions of physician empathy items were answered on a -point likert-type scale ( = strongly disagree, = strongly agree). all correlations were statistically significant (p< . ). croat med j ; : -

(p< . ). the reliability coefficient (the cronbach α coefficient of internal consistency) for the jef- ferson scale of patient’s perceptions of physician empathy was . which is relatively low, but with only five items in the scale it can be consid- ered satisfactory. the score distribution of the jefferson scale of patient’s perceptions of physician empathy was skewed toward the upper tail of the distribu- tion reflected in the mean score of . on a scale with a maximum score of , indicating that pa- tients expressed an extremely positive view of the residents’ empathic engagement (table ). correlations between each item of the jef- ferson scale of patient’s perceptions of physi- cian empathy and the total scores of the amer- ican board of internal medicine patient rating form ranged from a low of . to a high of . (table ). all these correlations were statistically significant (p< . ) with a median of . , in- dicating that the items of the jefferson scale of patient’s perceptions of physician empathy were significantly related to the evaluation of physi- cians’ communication skills, humanistic qual- ities, and professionalism as measured by the american board of internal medicine patient rating form, thus providing support for the valid- ity of the items. also, correlations between the total scores of the jefferson scale of patient’s perceptions of physician empathy and scores for each item of the american board of internal medicine pa- tient rating form were examined. the highest correlation (r = . ) was obtained for the fol- lowing item of the american board of internal medicine patient form: “(this physician) is in- terested in me as a person; does not act bored or ignore what i have to say.” the lowest correla- tion (r = . ) was found for the following item: “(this physician) explains what you need to know about your problems and what to expect in plain language.” the median correlation was . , and all correlations were statistically significant (p< . ). the correlation between the total score of the jefferson scale of patient’s perceptions of phy- sician empathy and the average scores of the american board of internal medicine patient ratings was .

fur- ther support the criterion-related validity of the jefferson scale of patient’s perceptions of physi- cian empathy. data for both the jefferson scale of patient’s perceptions of physician empathy and the jef- ferson scale of physician empathy were available for a small number of residents (n = ). correla- tion coefficient of the two scales for this group of residents was . , which did not reach the level of statistical significance (p = . ). discussion several conclusions can be drawn from the find- ings of the present study. first, the results of fac- tor analysis suggest that the jefferson scale of patient’s perceptions of physician empathy mea- sures a single factor that can be entitled physi- cian’s empathic engagement as perceived by the patient. second, findings that each item of the jefferson scale of patient’s perceptions of phy- sician empathy and its total scale score were sig- nificantly correlated with the responses on the selected criterion measures, including the total scores of the american board of internal medi- cine patient rating form provide evidence for the criterion-related validity of the jefferson scale of patient’s perceptions of physician empathy. third, a lack of significant correlation between patient’s perceptions of physician’s empathic en- gagement and the resident’s self-reported empa- thy deserve further clarification. a lack of rela- tionship on empathic understanding between therapists and patients has been reported ( ) and explained by factors such as residents’ inabil- ity to communicate their empathic understand- ing to their patients, or patients’ viewing em- pathic engagement differently from physicians. in another study with residents in a family med- icine program, a significant correlation (r = . , p< . ) was observed between the jefferson scale of physician empathy and the jefferson scale of patient’s perceptions of physician em- pathy scores (data not shown). we expected to find a significant overlap between scores of the jefferson scale of patient’s perceptions of phy- sician empathy and the jefferson scale of physi- cian empathy in the present study. the non-sig- nificant correlation we observed between these two measures could be due to the skewed score distribution of the jefferson scale of patient’s perceptions of physician empathy, restriction of range, and the ceiling effect. we examined the distribution of scores of the jefferson scale of pa- tient’s perceptions of physician empathy for the residents who completed the jefferson scale of physician empathy and found that a great ma- jority ( %) of them obtained the maximum score on the jefferson scale of patient’s percep- tions of physician empathy, leading to a severe skewed distribution and an extreme ceiling ef- fect. the true relationship between variables can- not be fully captured with such an extreme ceil- ing effect. more empirical research is needed to examine factors that contribute to the relation- ships between physicians’ self-reported empathy and patients’ perceptions of their physicians’ em- pathy in clinical encounters. it is generally believed that patient’s percep- tions of a caregiver’s empathy is associated with a positive treatment outcome ( , ), but empirical evidence in support of this proposition is rarely available. one reason for the scarcity of empiri- cal evidence is the absence of a psychometrically sound instrument for measuring patients’ per- ceptions of their physicians’ empathic engage- ment when rendering care. although additional studies are needed to further examine different aspects of psychometrics of the jefferson scale of patient’s perceptions of physician empathy in groups of physicians in different specialties and patients in different settings (outpatient, hospi- croat med j ; : - talized), our preliminary findings suggest that it is feasible to use this scale to study predictors and outcomes of patients’ perceptions of physician empathy. the external validity (generalization of the findings) of this study is limited because of the convenient sampling that included only residents in one residency training program who were not necessarily the primary caregivers of the patients. in this study, we used patients rather than the residents, as the unit of observation. some of the residents were evaluated by more than one pa- tient. our analyses showed that the pattern of findings remained generally unchanged when residents were used as the unit of observation. despite the study limitations, the findings generally suggest that it is feasible to use patients’ ratings of residents’ humanistic attributes in a residency clinic setting. this is important for the accreditation counsel for graduate medical education outcome project that emphasizes the centrality of the patient in the evaluation of resi- dents. we believe that greater use of the patients’ assessments of their care provider’s empathy as part of the evaluation of residents could have a significant impact upon the enhancement of pro- fessionalism in medicine. acknowledgments we would like to acknowledge the following individu- als for their contributions to

transfected into cho cells. the cho transfectants were char- acterized by facs and then scaled up for kinexa binding studies. kinexa has been used to measure binding affinity of adnectin-a to the cell surface ex- pressed receptor x to measure the effect of avidity of the multivalent adnectin binding to receptor clusters. as controls for the functional activity of the adnectin-a and the affinity of the monovalent interaction, the same kinexa assay was used, substituting the soluble receptor x extracellular domain for the transfected cho cells. the binding avidity measured by kinexa for cho expressed receptor is pm for both species of receptor x. however, the affinity of adnectin-a for monovalent soluble receptor x was quite different between the species suggesting that avidity due to receptor clustering equilizes the functional avidity at the cell surface. platform: voltage-gated k channels: activation/ inactivation mechanisms -plat a-type kv channel closed-state inactivation is modulated by the tetramerization domain interacting with auxilary kchip a yi-quan tang , fan yang , jingheng zhou , jie zheng , kewei wang . peking university, beijing, china, university of california at davis, davis, ca, usa. a-type kv potassium channels undergo a conformational change towards a non-conductive state at negative membrane potentials, a dynamic process known as closed-state inactivation (csi). csi causes inhibition of channel ac- tivity without prerequisite of channel opening, thus providing a dynamic regu- lation of neuronal excitability, dendritic signal integration and synaptic plasticity. however, the structural determinants underlying kv csi remain largely unknown. we have recently demonstrated that auxiliary kchip a sub- unit contains an n-terminal kv inhibitory domain (kid) that directly interacts with kv . channels to enhance csi. in this study, we utilized the fret two- hybrid mapping and bifc-based screening combined with electrophysiology, and identified the intracellular tetramerization (t ) domain that functions to suppress csi and serves as a receptor for the binding of kid. disrupting kv . t -t interaction by mutating c a within the c h motif of t domain facilitated csi, and ablated the kid-mediated enhancement of csi. furthermore, replacing the characteristic c h motif of kv . t domain with the t domain from kv . without the c h motif or kv . with the c h motif resulted in channels functioning with enhanced or suppressed csi, respectively. taken together, our findings reveal a novel role of the t domain in suppressing kv csi with the c h motif functioning to stabilize the channel activation gate; and kchip a kid directly interacts with the t domain to relieve the stabilization, leading to facilitation of csi and inhibition of channel function. -plat two-in-one: activation and inactivation at the intracellular gate of a kv channel manuel covarrubias , jeffrey d. fineberg . neuroscience, jefferson medical college of thomas jefferson university, philadelphia, pa, usa, physiology and molecular biophysics, jefferson medical college of thomas jefferson university, philadelphia, pa, usa. n-type and p/c-type inactivation are firmly established mechanisms of inac- tivation in voltage-gated kþ (kv channels). however, kv .x channel com- plexes, which undergo fast preferential closed-state inactivation (csi; fineberg et al., , jgp . : - ), appear to use a distinct but un- known inactivation mechanism. previously, we hypothesized that a weak interaction between the voltage sensing domain and the intracellular activa- tion gate underlies csi (bähring & covarrubias, , j physiol : - ). thus, csi is essentially governed by the intracellular activation gate, which fails to open and adopts an inactivated conformation. to directly test this hypothesis, we investigated the heterologously expressed kv . ternary channel complex including accessory subunits kchip and dpp , and ex- ploited the ‘‘trap-door’’ paradigm of the activation gate. the results show that kv . inactivation traps intracellularly applied quaternary ammonium blockers (btbua and tbua) inside the channel’s pore. the trapped blockers can only escape if the channels are opened again by subsequent depolariza- tions. by contrast, inactivation cannot trap tea, whose binding kinetics is faster than that of channel gating. moreover, under identical conditions, a shaker kv channel (shb-t k) known to exhibit fast p/c-type inactivation cannot trap btbua. these findings conclusively suggest that the intracellular activation gate of the kv . ternary channel complex plays a novel dual role, controlling both activation and inactivation. supported in part by nih grant r ns (mc). -plat development and validation

istanbul, turkey, biological sciences, institute for biocomplexity and informatics, university of calgary, calgary, ab, canada. the intra-cavitary drug blockade of herg channel, a common off-target for many drugs, have been extensively studied both experimentally and theoreti- cally. structurally diverse ligands inadvertent blockade of rapid component of delayed rectifying kþ currents are potentially pro-arrhythmic and may lead to drug-induced long qt syndrome-lqts. there are a number of natural strategies for rational drug design; one dubbed the ‘‘passive’’ approach avoids block of herg whereas the ‘‘proactive’’ strategy designs treatments to acti- vate the channel. while ‘‘passive’’ approach has been developed for decades, studies of structural mechanisms of herg channel activation by small mole- cules are truly novel. accordingly, design of the herg openers or current ac- tivators may offer a momentum for modern anti-arrhythmia drug development. significant number of small molecules with capacity for herg activation was identified in mandatory herg screens. to establish possible correlation be- tween activators structure and reactivity, we attempted to construct a universal pharmacophore model for herg channel openers using phase protocol. the biochemical data on kþ channel activators are used in training and test sets. these compounds span a wide range of structurally different chemotypes with ~ ^ -fold variances in binding affinity, which is sufficient for statistically sound model. a developed five sites aahhr (a, hydrogen-bond accepting, h, hydrophobic, r, aromatic) pharmacophore model has showed reasonable high statistical results compared to other constructed models and was selected for steric and electrostatic contour maps analysis. the predictive power of the model was also tested with external test-set (as true unknowns) compounds. pharmacophore model is also combined with previously developed receptor- based homology model of herg k channel and novel activators are generated and screened. the developed ligand-based models may serve as a basis for the synthesis of novel potential therapeutic herg activators. -plat n-terminal regulation of herg kd channel deactivation steven j. thomson, angela hansen, michael c. sanguinetti. nora eccles harrison cardiovascular research and training institute, university of utah, salt lake city, ut, usa. slow deactivation of herg (kv . ) potassium channels maintains ikr dur- ing final repolarization of the cardiac action potential and opposes asynchro- nous early depolarization. inherited point mutations in herg that accelerate deactivation of ikr cause long qt syndrome (lqts), a disorder of ventricular repolarization that increases the risk of lethal cardiac arrhythmia. the intracellular n-terminal domain of herg is known to be essential for slow deactivation. deletion of the entire (~ residues) or just the initial residues of the n-terminus accelerates deactivation -fold. the same effect is achieved by neutralization of the charged residues, arg or arg . how many of the n-termini are required to slow channel deactivation is unknown. herg , like other kv channels, is a homotetramer. by repeatedly linking the c-terminal of one subunit to the n-terminal of the next subunit we constructed concatenated herg tetramers. a variety of homomeric and heteromeric concatenated tetramers were characterized (i.e., wtn/r a:r a( -n); where n = to ). the concatenated channel containing a single r a/r a subunit and wild-type subunits deactivated as fast as the concatenated channel con- taining only r a/r a subunits. the lqts-associated mutation r q, located in the n-terminal of herg was also studied. again, a concatenated tetramer containing a single mutant subunit deactivated as fast as channels with r q mutations in all four subunits. our results show that all n-termini are required to mediate slow deactivation in wild-type herg channels. -plat

congress, thomas jefferson wrote, “with our indian neighbors the public peace has been steadily maintained. some instances of individual wrong have, as at other times, taken place, but in nowise implicating the will of the nation…. and, generally, from a conviction that we con- sider them as part of ourselves, and cherish with sincerity their rights and interests, the attachment of the indian tribes is gaining strength daily—is extending from the nearer to the more remote, and will amply requite us for the justice and friendship practised towards them” (http://memory.loc .gov/ammem/mtjhtml/mtjhome.html). now, years later, it can hardly be said that native americans have been the beneficiaries of overabundant “justice and friendship.” one need not recount their bar- baric treatment in the th century and the vestiges that remain on today’s reservations, but the social injustice that modern society affords the first americans does weigh on the conscience. large numbers suffer from poverty, poor housing, loss of culture, and sickness. the high disease rates and poor health care experi- enced by native americans are not unique but appear to be part of a global phenomenon among indigenous peo- ples, as the new zealander mason durie writes in this issue (p ). the public health histories of new zealand’s maori, australia’s aborigines, norway’s saami, native ha- waiians, and the first nations of canada bear striking re- semblances to historical and modern patterns among na- tive americans. a companion editorial by charles grim, director of the us indian health service, paints a more positive picture, noting recent advances in the health care of native americans (p ). for example, their life ex- pectancy has increased by years since . tribes are more engaged in self-management of health affairs. this is certainly good news, but there is still too much bad news. rates of cigarette smoking, binge drinking, and illicit drug use remain higher among native americans than among whites. fully % of native americans lack health insurance (the same is true for only % of whites). one out of every native american youths has not been to a doctor within the year. infant, neonatal, and post- neonatal mortality rates are % higher than those of whites. among adults, % of whites—but % of native americans—rate their health as fair or poor. having a chronic disease limits activity for % of whites but for % of native americans. among women age and older, more than % of whites but only % of native americans have had a recent mammogram. society faces an ethical imperative to address the socio- economic deprivation of native americans that lies at the heart of these disparities if, as jefferson wrote, we “con- sider them as part of ourselves, and cherish with sincerity their rights and interests.” otherwise, it can be said that inaction is, indeed, “implicating the will of the nation.” ✦ —steven h woolf, md, mph o n a p ril b y g u e st. p

science+business media new york one of the missions of the neurocritical care society (ncs) is to foster clinical, experimental, and outcomes research focused on developing innovative and cost-ef- fective medical and surgical interventions for acute neurological disorders. to achieve this mission, ncs cre- ated a research committee. this committee organized the neurocritical care research conference. the most im- portant outcome of the first neurocritical care research conference (september ) was the creation of the neurocritical care research network (ncrn) [ ]. fol- lowing the success of that first endeavor, the second neurocritical care research conference took place in houston, tx may – , . this symposium was funded by ninds ( r ns - , p.i. jose i. suarez), baylor st. luke’s medical center (neuroscience center) in houston, and the integra foundation and endorsed by the baylor college of medicine (bcm) and the ncs. the overall goal of this interdisciplinary scientific gathering was to bring together a diverse group of aca- demic scientists and physicians with a common interest in understanding and advancing research in multimodality monitoring in neurocritical care diseases, in large part be- cause monitoring patient disease and care is a fundamental aspect of neurocritical care. the need for the design of adequate clinical studies to test these monitoring techniques was addressed in the context of the recently created ncrn to facilitate collaboration and patient en- rollment. in addition, this conference provided a unique opportunity for trainees, junior faculty, and other scientists to interact with investigators in the field of neurocritical care. the conference opened with a discussion on new approaches to multifaceted therapeutic bundles in neuro- critical care followed by five scientific sessions: ( ) global brain monitoring in the neurocritical care unit; ( ) re- gional brain monitoring in the neurocritical care unit; ( ) data collection and interpretation; ( ) conventional clinical trial design of multimodality monitoring; and ( ) alternative clinical trial design. the meeting had registrants and attendees. this represents a % increase in attendance compared to our first research conference. attendees came from all parts of the world including the united states, canada, latin america, europe, japan, india, and the middle east. we had lively and interesting discussions throughout the meeting. the conference was successful and well received with % stating that it was fair and balanced. at the end of the meeting, there was consensus on two major points: ( ) we need a common language to describe the technology available and the information it provides to pursue further research to advance the field and ( ) technology alone will not impact upon clinical outcome without specific inter- ventions and pathways that can modify and ameliorate the biochemical cascade unleashed by brain insults. two pro- jects have since evolved from the second neurocritical care research conference: ( ) the international multidis- ciplinary consensus conference on multimodality monitoring in neurocritical care, a collaboration between the ncs, the european society of intensive care medicine, the society of critical care medicine, and the latin & jose i. suarez jisuarez@bcm.edu division of vascular

in brain p h o t o : a v e s u n / is t o c k p h o t o october • vol issue s c i e n c e sciencemag.org meditation and yoga associated with changes in brain brain researchers have detected improvements in cognition and emotional well-being associated with meditation and yoga, as well as differences in how meditation and prayer affect the brains of those who believe in god and those who do not. at a september neuroscience & society event cosponsored by aaas and the dana foundation, neuroscientist sara lazar said that not only were the brain images in a study of people who meditated different from those who did not, other research showed that certain changes in performance such as improved scores on the graduate record exam (gre) occurred in controlled experiments involving mindfulness training. “this suggests neuroplasticity to me,” said lazar, associate researcher in the psychiatry department at massachusetts general hospital and an assistant professor in psychology at harvard medi- cal school, “the ability of your brain to change, to grow and adapt” in correlation with meditation. aaas and the dana foundation have collaborated on the neuro- science & society lecture series since , with events so far reaching attendees. the purpose of the series is to provide a public forum for experts to share the latest advances in brain research and what they might mean for individuals and society. in another presentation at the event, chris streeter, associate professor of psychology and neurology at boston university school of medicine, reported that the brain chemical gaba, a neurotrans- mitter associated with control of anxiety, peaked in experienced yoga practitioners after they executed minutes of postures. “that was the first time people could say there was a change in brain chemistry associated with yoga,” streeter said. in order to test whether yoga improved mood and lessened anxiety more than other physical exercise, study subjects were tested before and after a -week intervention in which they did yoga or walked. the activities were metabolically matched to involve the same amount of physical exercise. the yoga group consistently felt better, according to various mark- ers of mood and anxiety, streeter said. an hour after the yoga, acute changes—revitalization, tranquillity, positivity, and increases in gaba levels—were reported. in depressed patients, even those already on antidepressants, yoga was associated with improved sleep, increased positivity, and decreased suicidal ideation (although none of the participants had shown intent to commit suicide). all the measurements indicating mood began “moving in the right direction,” streeter said. in contexts involving meditation and prayer, brain scans show differences in how the brain reacts depending on whether a subject believes in god, said andrew newberg, director of research at the marcus institute of integrative health and a physician at thomas jefferson university hospital. according to one of newberg’s studies, when nuns contemplated god, activation was detected in images of the prefrontal cortex, the center of cognitive control, but there was no such activation in the brains of atheists. newberg also discussed brain chemistry changes associated with retreat experiences involving prayer, meditation, and silence. tests from before and after the retreat experience showed decreases in dopamine and serotonin transporter levels, which w ould allow the neurotransmitter chemicals to be stored in the brain for later use. finishing his presentation, newberg said the work of all three researchers could be seen as interconnected. “all of this work is coalescing and helping us to understand the overall nature of these experiences,” he said. neuroscientists describe improvements in cognition and mood at aaas event by michaela jarvis a a a s n e ws & n o t e s studies of meditation and yoga report changes in brain

(ii) the constraints in the primal problem are absorbed into the dual ob- jective function. in this way, while the primal program may have non- linear constraints, the dual may be simply an optimization over a poly- hedral set. joint utilization of the primal and dual objectives yields a powerful algo- rithmic stopping criteria; i.e. the sum of both objectives is less than some specified tolerance. finally, the dual often gives a different perspective to the problem which has useful interpretational insights. many examples are given in peterson [ ] and focused applications on location theory may be found in scott, jefferson and jorjani [ ]. as stated earlier, we will be concerned with the so called “unconstrained” version of generalized geometric programming which in conventional terms means a finite dimensional convex programming problem with the con- straint set being a cone. reason (ii) above refers to the constrained theory [ ]. in this paper, we present the theory pertaining to this particular prob- lem type and then we look at the application to two problems of inventory control, clark and scarf [ ], modigliani and hohn [ ]. these seemingly unrelated models are in fact, related in the sense of duality. duals for classical inventory models . generalized geometric programming we consider an optimization problem of the form: minimize f (x) over x ∈ c ∩ χ ( ) where χ is a cone in en and f is a closed convex function with domain c. this problem is termed the primal problem. we associate with the primal problem, another problem, called the dual problem, which is of the form: minimize g(y) over y ∈ d ∩ χ∗ ( ) where χ∗denotes the polar cone of χ in en and [g: d] is the conjugate transform of [f : c] with value g(y) = sup x∈ c (xt y − f (x)), ( ) d = {y ∈ en|xt y − f (x) < ∞} ( ) and χ∗ = {y |xt y ≥ ∀x ∈ χ} ( ) we note that the primal and dual problems are essentially of the same form and hence are termed symmetric. at optimality, the following relationships hold between the primal the primal and dual optimal points, x and y respectively. f (x ) + g(y ) = ( ) y ∈ ∂ f (x ) , x ∈ ∂ g (y ) ( ) xt y = ( ) these optimality conditions allow an optimal point for one program to be calculated from an optimal point of the other. here ∂ f (x ) denotes the subgradient set of f at x . that is, ∂ f (x ) = {y |f (x )+ < y, x − x >≤ f (x), ∀x ∈ c} ( ) for full details of the theory given in this section the reader is referred to peterson [ ]. c. h. scott, t. r. jefferson, and s. jorjani . a multi-echelon inventory model for a storage network, with n facilities in series, uncertain demand d, occurs at facility n only. shortages are passed up the line to n − , then n − if n − is out of stock, etc. facility n may be a retail store, whereas facility may be a distant warehouse where storage costs are much lower. let ui be the sum of stock on hand at facilities i, i = , . . ., n. hence u ≥ u ≥ ... ≥ un ( ) at the beginning of a planning period, each facility places an order with immediate delivery. let ci denote the amount by which the unit capital charge on ordering at facility i exceeds that at i− and c = . similarly let hi denote that amount by which the unit storage cost at facility i exceeds that at facility i − and h = . we note that ci ≥ , hi ≥ is reasonable since distant warehouses may have smaller holding and ordering costs than retail stores within a city. let pi denote the unit shortage cost at facility i. hence the total costs incurred are∑ i ciui + n∑ i= (pi e [d − ui]+ + hi e [ui − d]+) ( ) which represent the ordering cost, expected shortage cost and expected holding cost respectively and ζ+ = max[ζ, ]. hence we obtain the following optimization problem: minimize the convex function∑ i (ci − pi)ui + ∑ i (pi + hi)e[ui − d]+ + ∑ i pie[d] ( ) subject to equation ( ), ui ≥ ui+ i = , , ...., n- ( ) in the generalized geometric programming form, we have to minimize ∑ i aiui + bi d=ui∫ d= (ui − d)f (d)dd ( ) subject to the cone condition p u ≥ ( ) duals for classical inventory models where ai = (ci −pi), bi = (pi +hi), u = (u , ...., un)t and p is an (n− )×n matrix with elements pij = + for i = j and pij = − for j = i + . f denotes the probability density function of demand. for the dual problem, we require the conjugate transform of the objective function, equation ( ), and polar of equation ( ). taking the conjugate transform defined by equations ( ), of ( ) results in the supremum being attained when vi − ai − bif (ui) = ( ) where vi is the dual variable corresponding to ui and f is the cumulative distribution function of demand. hence, solving equation ( ) for ui we have that ui = f − ((vi − ai)/bi) hence the dual objective function is ∑ i (vi − ai)f − ((vi − ai)/bi) − bi d̂∫ d= (f − ((vi − ai)/bi) − d)f (d)dd − ∑ i pie[d] ( ) where d̂ = f − ((vi − ai)/bi). the polar cone is given by {v |v t u ≥ ∀ u s.t. p u ≥ } ( ) equation ( ) readily implies that v = p t z, z ≥ ( ) where z is an n − dimensional vector. expanding equation ( ), we have that v = z vi = zi − zi− i = , ..., n − vn = −zn− ( ) we note that the dual problem, i.e. the minimum of equation ( ) subject to equations ( ) and z≥ is a discrete time optimal control problem, c. h. scott, t. r. jefferson, and s. jorjani where zi, i = , ..., n − are the state variables and vi, i = , ..., n are the control variables. several other models which fit into this framework may be found in muck- stadt and roundy [ ] and a specialized algorithm has been given by scott and tang [ ]. a numerical example follows: suppose the demand d follows an exponential distribution with mean λ. hence f (d) = /λ exp(−d/λ), f (u) = − e−d/λ and f − (α) = −λ ln( − α) it follows that the primal objective given by equation ( ) is∑ i ((ai + bi)ui + biλe −ui/λ − hiλ) the corresponding dual objective is from equation ( ) ∑ i (λ(ai + bi − νi) ln( ai + bi + νi bi ) − ciλ + νiλ) where the primal and dual variables are related by ui = −λ ln( ai + bi − νi bi ) i = ,..,n we now particularize to the following data set. n = , λ = , c = ( , , ), h = ( , , , ), p = ( , , ). in this case, the minimal cost is . with optimal dual variables ν = ( , . , − . ) and corresponding primal variables u = ( . , . , . ).this implies that it is optimal to hold . units of inventory at facility and the remaining . at facility . . an inventory-production control model a well-known problem in inventory control is to select a set {xt ≥ t = , ..., t} of production levels to minimize, over a planning horizon of length duals for classical inventory models t, the sum of production and holding costs, while meeting demand. for- mally the problem may be posed as: minimize t∑ t= (c(xt) + htyt) ( ) subject to the inventory balance dynamics y = x − d yt − yt− = xt − dt t = , ..., t − −yt− = xt − dt ( ) and the non-negativity constraints yt ≥ t = ,..., t xt ≥ t = , ..., t ( ) here yt denotes the inventory level in period t, dt is the demand in period t, c(xt) is the production cost (assumed convex and strictly monotonically increasing) and ht is the holding cost per unit in period t. to invoke the theory of generalized geometric programming, we need to put the constraint equations ( ) and ( ) into a cone. hence we intro- duce a new variable αt, t = , ..., t and restrict it to a one point domain {dt}, t = , ..., t . this variable is then associated with an additive com- ponent of the objective function which is identically zero. hence we obtain a cone condition y - x + α = yt − yt− − xt + αt = t = , ..., t − −yt− − xt + αt = yt ≥ t = , ..., t ( ) it is convenient to treat the other non-negativity constraint xt ≥ , t = , ..., t as an implicit one. our problem is now in a form which is directly suitable for application of the theory. the dual objective is given by sup xt, yt, αt xt ≥ ∑ t (xtut + ytvt + αtβt − c(xt) − htyt) = sup xt≥ ∑ t (xtut − c(xt)) + sup αt ∑ t αtβt + sup yt ∑ t (ytvt − htyt) = ∑ t c∗(ut) + dtβt ( ) c. h. scott, t. r. jefferson, and s. jorjani where c∗(ut) = sup xt≥ (xtut − c(xt)) ut ∈ ∂ c(xt) and vt = ht ( ) usually c(xt) is a quadratic function and c∗(ut) is readily calculated. fur- ther we require the polar to the cone defined by equations ( ) i.e. {(ut , vt, βt)| ∑ t (utxt+vtyt+βtαt) ≥ ∀ xt, yt, αt satisfying equations ( )} a straightforward calculation shows that vt = pt − pt+ + qt t = , ..., t − ut = −pt t = , ..., t βt = pt t = , ..., t qt ≥ t = , ..., t hence the dual problem is to minimize t∑ t= (c∗(−pt) + dtpt) subject to pt − pt+ + ht ≤ t = ,...,t- for constant ht, we have a minimization over a monotonically increasing set of decision variables. a numerical example follows: suppose c(xt) = x t for t = and h = ( , ), d = ( , , ). in this case, c∗(pt) = p t / with pt = xt. the primal program is minimize ∑ t= x t + y + y subject to: y = x − y − y = x − − y = x − and x ≥ , y ≥ duals for classical inventory models the corresponding dual program is: minimize ∑ t= p t + p + p + p subject to : p − p − ≤ p − p − ≤ solving the dual program yields the optimal value of – , . with opti- mal solutions p = (− . , − . , − . ). the corresponding pri- mal program has minimal cost , . with optimal solution (rounded) x = ( , , ) and y=( , ). . conclusions the two inventory problems considered suggest an interesting duality be- tween certain problems of discrete time optimal control and static opti- mization over monotonic sequences. the multi-echelon inventory model considered in section is a static optimization over monotonic sequences and the geometric dual is a discrete time optimal control problem. the reverse is the case for the production planning problem treated in section . problems of both type arise naturally in inventory control. further, with a dual problem we are in a far better position to develop efficient computational algorithms that if only the primal is considered. references . balachandran, v. and gensch, h.

(b) the percent changes in the dtc advertis- ing spending and drug price. the percent change in dtc advertising spending and drug price for a year was calculated as percent change from the previous year. results: only sildenafil (viagra) and sibutramine (meridia) showed an increase in the actual drug price with an increase in the dtc advertising spending. however, for these two drugs in year , the percent change in dtc advertising spending decreased and the percent change in drug price increased. no trend was evident from the graphs of the other eighteen drugs. on an average dtc advertising spending for most of the drugs decreased with time while drug prices continued to increase. conclusion: results indicate a very weak relation- ship between dtc advertising spending and drug prices. the increase in drug price in spite of the decrease in the dtc advertising spending contradicts both rationale i.e. dtc advertising spending reduces drug price through competition or increase in drug price is due to increase in dtc advertising spending. hp impact of direct to consumer advertising—the consumer search for information belazi dt , crawford a , pizzi l thomas jefferson university & abbott laboratories, philadelphia, pa, usa; thomas jefferson university, philadelphia, pa, usa objective: the purpose of this study is to identify factors associated with consumers’ seeking various infor- mation sources about medications sought in response to direct to consumer advertising. methods: in the spring and summer of , the fda, division of drug marketing, advertising, and commu- nication conducted a national telephone survey of adults regarding direct-to-consumer (dtc) promotion of prescription drugs and its effects on visits to the doctor. in addition to consumer attitudes, opinions and responses to direct to consumer advertising, the survey also elicited responses regarding consumer utilization of information sources such as reference books, -telelphone number, and health care providers. there were total respon- dents, of whom completed the required questions regarding information sources. chi square analysis was used to assess associations between consumer demographic information and the different types of informational resources that consumers used after exposure of direct to consumer advertising. results: the analysis showed significant associations (p £ . ) between gender, race, education, health status, self-perceived knowledge of health, prescription medication use, and internet use and many of the following information resources: reference books, asking friends/neighbors, -telephone number, primary doctor, pharmacist, specialist, and nurse. across all information sources, female gender, decreased health status, low education, and higher than average medica- tion use were the variables that had the strongest associ- ations. a model was developed depicting the associations between these findings. results pertaining to specific sources will be presented. conclusions: this study evaluated how different consumers seek information from different sources as a result of direct to consumer advertising. this study will assist those interested in identifying and further educat- ing consumers about their health and novel treatments or therapies. hp fda regulatory actions against misleading or unsubstantiated economic and quality-of-life claims: an analysis of warning letters and notices of violation stewart ka, neumann pj harvard school of public health, boston, ma, usa abstracts objectives: to examine the frequency and nature of fda regulatory actions against pharmaceutical compa- nies for unsubstantiated or misleading economic and quality-of-life (qol) claims. methods: review of publicly-available fda warning letters and notices of violation (n = ) sent to pharma- ceutical companies between january and november for inappropriate promotional claims. a standard data collection form was developed to capture the frequency and type of violation and the medium in which violations were found. we classified economic violations into several categories (e.g., “unsupported comparative claim of effectiveness, safety or interchangeability,” “claims of cost-savings when there are obvious additional costs that may affect cost savings,” “implied claims of cost-savings to a broader audience than applicable”). qol violations for false or misleading claims using the words improved ‘quality of life’ or ‘patient well-being’ were classified into the following categories: “lack of substantial evidence for qol claims,” “promoting qol claims in investigational or unapproved drug,” and “selective presentation of qol information”. results: ( . %) letters cited false and/or mislead- ing economic claims. the most common economic viola- tion was an economic claim containing an “unsupported comparative claim of effectiveness, safety or interchange- ability” (n = ). ( . %) letters cited qol violations ( letters contained both economic and qol violations). the most common qol violation was “lack of substan- tial evidence for qol claims” (n = ). violations were found most frequently in brochures and on websites. conclusions: a body of evidence is emerging that illustrates how the fda is regulating promotional mate- rial containing misleading or unsubstantiated economic and qol claims. knowing what constitutes an economic or qol violation remains unclear, because there are no formal guidelines about what constitutes a violation, nor what level of substantiating evidence is required. more guidance may be needed to ensure appropriate use in drug promotions. asthma & respiratory disorders/infections ar relationship between different measures of asthma severity: patient- perceived, symptom derived, and fev determined severity measures erickson sr, kirking dm, bria wf university of michigan, ann arbor, mi, usa objective: in health services research, obtaining objective measures of pulmonary function to classify asthma severity is often not possible. researchers must rely on methods such as frequency of self-reported symp- toms and patient perceived severity. this study examined the relationship between fev determined severity and severity determined by patient-reported information. methods: data from adult patients with asthma were obtained from a pulmonary clinic via chart review and patient self-report during a scheduled physician visit. patients in acute exacerbation were excluded. patient- perceived severity (pps) was determined by asking “how severe do you think your asthma is?” with a five-point likert scale from very mild to very severe. overall symptom-derived severity (oss) and nocturnal symptom-derived severity (nss) were determined from two separate questions regarding symptom frequency during the preceding four weeks. responses were based on the nhlbi asthma guidelines. pulmonary func- tion tests were obtained the same day as part of standard care. fev -determined severity (fev -ds) was derived by comparing the fev with the guideline classification of severity based on spirometry. three severity categories were derived for each severity method. percent agreement between fev -ds and each patient-reported severity was determined by constructing ¥ tables. correlations (spearman’s rho) were conducted between fev -ds and the patient-reported severity measures. results: patients with a mean fev percent predicted of . % ( . ) were studied. the percent agreement between fev -ds and pps was . % ( . % over-estimate, . % under-estimate); . % between fev -ds and oss ( . % over-estimate, . % under-estimate); and . % between fev -ds and nss ( . % over-estimate, . % under-estimate). the correlations between fev -ds and pps were . (p < . ); . with oss (p < . ); and . with nss (p = . ). conclusions: pps and oss demonstrated reasonable agreement and correlation to fev -ds, albeit opposite trends in over- and under-estimates. these two measures of asthma severity appear useful for population based studies when fev is unavailable. ar directly elicited preferences compared to preferences derived from the sf- in adult

algorithms have been developed to derive preference estimates from the sf- . the objective of this study was to compare the validity and responsiveness of sf- derived preference estimates to directly elicited preferences in persons with persistent asthma. methods: we used data from a one-year clinical trial of adult asthmatics to derive preferences from the sf- . preferences were estimated using five published algo- rithms for converting sf- scores to non-choice based preference estimates. derived preferences were compared to directly elicited visual analog scale (vas) values. dichotomy between mitochondrial ca + uptake and martix [ca +] in micu deficient cells sunday, february , a mitochondrial membranes which result in the dramatic increase of their perme- ability. this increase in permeability during necrosis is caused by the opening of a permeability transition pore - ptp in mitochondrial inner membrane. on the other hand apoptosis induces opening of a large non-selective channel (mito- chondrial apoptotic channel - mac) in the mitochondrial outer membrane. we used atomic force microscopy to study the structure and organization of native mitochondrial membranes isolated from necrotic and apoptotic cells. we com- plement our afm imaging with nanopatricle-based immnunoassays, where mi- tochondrial membranes are pretreated with nanoparticle-conjugated antibodies for recognition of specific proteins. we will present our data on morphological studies of these membranes and will discuss feasibility of this approach for visu- alization of mptp and mac channels in the native mitochondrial inner mem- branes (mim) and mitochondrial outer membranes (mom) using afm methods. -pos board b heterogeneity of cardiolipin regulation yi-fan lin, mei-jie jou. department of physiology and pharmacology, chang gung university, tao-yuan, taiwan. cardiolipin (cl), is a protective phospholipid located exclusively on the mito- chondrial inner membrane for stabilizing individual complex of mitochondrial respiratory chain for energy production, mitochondrial ca þ (mca þ) regula- tion and reactive oxygen spices formation. deficiency of cl has been associated with multiple mitochondrial dysfunctions upon pathological condition, diseases and aging. using fluorescence digital imaging microscopy this study investi- gated how cl is preciously regulated in rat brain astrocytes rba- . results demonstrate that at the resting stage, the distribution of cl is rather heteroge- neous within single cell. the perinulear mitochondria show lower cl than mi- tochondria from the peripheral area. heterogeneity of cl was observed even in single mitochondrion, which may affects mitochondrial fission and fusion mechanism. cl was found to be higher at the cross point area of mitochondrial network. thread-like mitochondria and granular-like mitochondria, however, contain similar level of cl. some of the thread-like mitochondria even contain lower cl than granular-like mitochondria. upon localized oxidative stress in- duced by nm laser irradiation, heterogeneous depletion of cl was observed among mitochondria populations within single cell. distribution of cl altered also mitochondrial dynamics that depletion of cl always occurred before fis- sion. intriguingly, although complete depletion of cl is irreversible upon high strength of laser irradiation, depleted cl recovered during lower strength of laser irradiation and occurred heterogeneously within mitochondria popula- tions. condensation of cl was observed upon various stresses including oxida- tive stress induced by nm laser irradiation, ionomycin-induced mca þ stress and arachidonic acid-induced lipid stress which crucially enhances pres- ervation of cl and its resistance to stress which may be of significance for mi- tochondrial protection and survival. unveiling pathophysiological regulation of cl thus may contribute significantly the prevention and treatment of cl asso- ciated pathological condition, diseases and aging. -pos board b mtdna t g mutation-induced mitochondrial complex v inhibition augments cardiolipin-dependent alterations of mitochondrial dynamics during oxidative, ca d and lipid insults in narp cybrids: a potential therapeutic target tsung-i peng , chia-wei hsiao , mei-jie jou . keelung chang gung memorial hospital, tao-yuan, taiwan, national tsing hua university, tao-yuan, taiwan, chang gung university, tao-yuan, taiwan. mitochondrial dynamics including morphological fission and mitochondrial movement are essential to normal mitochondrial and cellular physiology. this study investigated how mtdna t g (narp)-induced inhibition of mito- chondrial complex v altered mitochondrial dynamics in association with a pro- tective mitochondrial phospholipid, cardiolipin (cl), as a potential therapeutic target. narp cybrids harboring % of mtdna t g genes and its parental osteosarcoma b cells were studied for comparison, and protection provided by melatonin, a potent mitochondrial protector, was explored. we demonstrate for the first time that narp mutation significantly enhances apoptotic death as a result of three distinct lethal mitochondrial apoptotic insults including oxida- tive, ca þ and lipidstress. in addition, narpsignificantly augmented patholog- ical depletion of cl. narp-augmented depletion of cl results in enhanced retardation of mitochondrial movement and fission and later swelling of mito- chondria during all insults. these results suggest thatcl is a common and crucial pathological target formitochondrial apoptoticinsults. furthermore, cl possibly plays a central role in regulating mitochondrial dynamics that are associated with narp-augmented mitochondrial pathologies. intriguingly, melatonin, by differ- entially preserving cl during various stresses (oxidation > ca þ > lipid), res- cuesdifferentially cl-altered mitochondrial dynamics and cell death (oxidation > ca þ > lipid). thus, melatonin, in addition to being a mitochondrial antioxidant to antagonize mitochondrial oxidative stress, a mitochondrial permeability tran- sition modulator to antagonize mitochondrial ca þ stress, may stabilize directly cl to prevent its oxidization and/or depletion and, therefore, it exerts great po- tential in rescuing cl-dependent mitochondrial dynamics-associated mitochon- drial pathologies for treatment of narp-induced pathologies and diseases. -pos board b shuttling of membrane-bound cytochrome b between mitochondria and er david weaver , veronica eisner , peter varnai , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis medical university, budapest, hungary. cytochrome b type b has long been described as a tail-anchored protein of the outer mitochondrial membrane (cb -mito). using a fusion protein consisting of photoactivatable gfp fused to the c-terminus membrane-targeting segment of cb -mito, we have found that while this construct concentrates in the mitochon- drial membrane, it is continuously exchanged between the membranes of the mitochondrion and the endoplasmic reticulum. this effect does not depend on the presence of mitofusin or , as it occurs in mfn-null mefs as well as in wild type cells. interestingly, a point mutation in the hydrophobic, membrane-targeting sequence of cb -mito that was recently reported to prevent its association with autophagosome membranes, also eliminates its exchange with the er. while lipids and viral proteins have been shown to traffic from er to mitochondria, this is, to our knowledge, the first demonstration of such a back-and-forth shuttling, representing both a new aspect of the er- mitochondrial interface and an mfn-independent pathway for the exchange of an outer mitochondrial membrane protein. -pos board b dichotomy between mitochondrial ca d uptake and martix [ca d] in micu deficient cells tunde golenar , gyorgy csordas , fabiana perocchi , vamsi k. mootha , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, harvard medical school and massachusetts general hospital, boston, ma, usa. mitochondrial calcium uptake is central to cell physiology, but the underlying molecular mechanism remains elusive. recently, micu was identified as a mi- tochondrial protein required for ca þ uptake but dispensible for mitochondrial respiration or membrane potential generation. to study the specific role of micu in mitochondrial ca þ uptake, we used wild type hela cells (ctrl), micu knockdown by distinct shrnas (kd) and micu rescued cells (res- cue). first, we monitored the cytoplasmic and mitochondrial matrix [ca þ] ([ca þ]c and [ca þ]m, respectively) during store-operated ca þ entry. specif- ically, cells were preincubated in a ca þ-free buffer containing thapsigargin (tg), to deplete the er ca þ store, and then ca þ was added back and the en- suing [ca þ]c (fura ) and [ca þ]m (mitochondria-targeted pericams) changes were measured. in both ctrl and kd a [ca þ]c increase occurred that was asso- ciated with a [ca þ]m rise only in ctrl. the rescue behaved similarly to the ctrl. also, when ca þ was added to permeabilized cells, no [ca þ]m increase ap- peared in the kd. these results confirm that the shortage of micu causes sup- pression of the [ca þ]m signal. surprisingly, when the ca þ entry was followed byuncoupler additiontoreleasethemitochondrial ca þ content, ahuge[ca þ]c increase appeared in kd, however, when the uncoupler was added prior to ca þ entry, no [ca þ]c increase occurred. thus, mitochondria in the kd also accumu- lated ca þ during ca þ entry. mitochondrial ca þ uptake evoked by ca þ ad- dition was also documented in permeabilized kd by measurement of ruthenium red sensitive ca uptake and cytoplasmic ca þ clearance (fura ). thus, ca þ is accumulated by micu deficient mitochondria but it fails to result an increase in[ca þ]m.weare currentlyinvestigating, whether suppression ofthe [ca þ]m rise in the kd is due to enhanced matrix ca þ-buffering. -pos board b micu serves as a ca d-controlled gatekeeper for the mitochondrial ca d uniporter györgy csordás , tünde

later the patient complained of horizontal diplopia. on examination visual acuities were unchanged, but the conjunctiva was diffusely inflamed and chemosed bilater- ally. colour vision was reduced on both sides on testing with ishihara plates ( / right and / left). there was no proptosis but the eyes felt hard to retropulsion on both sides. the intraocular pressures were now mm hg and mm hg, increasing to mm hg and mm hg on upgaze. a diagnosis of dys- thyroid eye disease was made and the patient treated with acetazolamide mg three times daily and prednisolone mg daily. thyroid function tests, full blood count, erythrocyte sedimentation rate, urea and elec- trolytes were all normal. a computed tomo- graphy scan showed marked increase in size of all the extraocular muscles but particularly the medial rectus on both sides (fig ) with crowding of the orbital apex suggestive of dys- thyroid eye disease. over the next week there was gradual improvement in both symptoms and clinical signs. steroids were gradually reduced and at his last visit weeks after the episode the visual acuities had returned to / right and / left with all ishihara plates seen on both sides. the chemosis had resolved and there was a full range of extraocular move- ments. comment dysthyroid eye disease is described by duane' as an organ specific autoimmune disease with a tenuous link to thyroid disease. it is charac- terised histologically by inflammation, oedema, and secondary fibrosis and clinically by proptosis, eyelid oedema and retraction, conjunctival chemosis, extraocular muscle abnormalities, and optic neuropathy. the aetiology is thought to be an autoimmune process possibly due to an altered antigen on a follicular cell that stimulates antibody produc- tion which cross reacts with extraocular tissue. alternatively, the primary problem may be a deficiency in suppressor t cell function and a breakdown of the immune system's ability to recognise self tissue. extraocular tissue is thus recognised as foreign and an immune re- sponse mounted against it. amiodarone is a class iii antiarrhythmic and chemically a benzofuran derivative. it is extensively plasma protein bound and is structurally similar to thyroxine. amiodarone has been reported in the medical literature to cause both hypothyroidism and hyperthy- roidism' which ophthalmologists should be aware of. treament with amiodarone has also been shown to result in in the production of both antithyroid antibodies and anti- amiodarone antibodies. previous studies have shown a positive correlation between the pres- ence of anti-amiodarone antibodies and the development of amiodarone induced side effects suggesting an immunological basis of these side effects. these ocular side effects may occur in the presence of normal or increased thyroid function. we suggest that amiodarone induced an exacerbation of thyroid eye disease in our patient already suffering from hypothyroidism either by acting as a stimulus for the production of antibodies that cross reacted with extraocular tissue or by the direct stimu- lation of t cells and a breakdown of the self recognition process. s banerjee c b

fre- quently originate from bronchus in contrast with orbital carcinoid metastases which may originate from the gastrointestinal tract. they may have a characteristic orange appear- ance,' in contrast with most other choroidal metastases which have a creamy yellow colour.' the interval between diagnosis of the primary carcinoid tumour and uveal metas- tases may be as long as years (mean years) and in over % ofpatients the primary lesion is undiscovered at the time of ocular diagnosis. unlike breast and lung uveal metastases,' the mean survival after diagnosis of uveal carcinoid metastases approaches years. the occurrence of orange choroidal lesions should raise the possibility of carcinoid metastases and prompt an intense search for a primary lesion, directed principally at the lung, or if the primary is known, for systemic recurrence elsewhere. at least % of cases are likely to have other metastases at the time ocular involvement is diagnosed.' in this case, however, systemic evaluation was unre- markable. a urinary hiaa was not per- formed as this had not been helpful in previous cases.' close follow up is required to detect tumour activity, either growth or the development of subretinal fluid or haemor- rhage. external beam radiotherapy ( - cgy) caused effective tumour regression in six of eight treated cases,' and is advocated if activity occurs. support

/s - - -z © society of general internal medicine w e appreciate the response from hojat and colleaguesregarding our study. in our manuscript, we extensively outlined reasons why we might not have been able to replicate the original study’s findings. those that the authors proposed in their letter, however, are unlikely causes. they propose our findings may have differed due to the mandatory communication trainings at cleveland clinic. yet our methods stated the jefferson scale of empathy (jse) scores used in our study were collected prior to training exposure. it’s true we had a larger proportion of internal versus family medicine physicians and a moderately different case mix of patients, but our finding of no association between empathy and diabetes outcomes was consistent in all multi- variable and sensitivity analyses. whether using their empathy cut points, analyzing scores continuously to maximize statis- tical power, or looking at subsets of patients with poorly controlled diabetes, we found no relationship between jse and outcomes. as described in detail in our paper, our inability to repro- duce the original study’s conclusions is not unusual—research findings are often reversed. this is why it’s important to replicate studies. it may be true that empathy was associated with diabetic control among patients of family medicine physicians at thomas jefferson > years ago, but their conclusion that “physician empathy is an important factor associated with clinical competence and patient outcomes” is not true now, at least not at the cleveland clinic. finally, the authors cite our “error in judgment” for acknowl- edging that the two studies that found correlations between empathy and diabetes outcomes were conducted by the same group. we fear they felt we were impugning their integrity, which is not the case. research shows even when studying the same data, different researchers often come to different conclusions, highlighting the benefit of having multiple groups independently study similar topics. additionally, financial in- terests have been shown to lead to unconscious biases, and investigators that are professionally invested in a specific field may be more likely to see associations in data than impartial methodologists. these implicit phenomena are reasons that authors are required to disclose financial conflicts of interest, and less commonly, professional ones. we have no specific stake in the outcome of this study. we hope that others will also attempt to replicate this work and add to our knowledge about the impact of empathy on patient outcomes. corresponding author: kathryn a. martinez, phd, mph; center for value-based care research cleveland clinic, cleveland, oh, usa (e-mail:

binding energetics of a potassium channel inactivation gate gaurav venkataraman, deepa srikumar, miguel holmgren. nih, bethesda, md, usa. voltage-activated potassium (kv) channels open an intracellular gate in re- sponse to changes in transmembrane voltage, allowing k þ to permeate at rates near diffusion. in some kv channels, permeation can be interrupted by the n-terminus of the protein acting as a blocking particle, binding at the intracel- lular cavity of the channel and physically obstructing the permeation pathway. despite being tetramers, kv channels require only one bound n-terminus to inactivate. in nature, inactivation is targeted by rna editing, which converts an isoleucine of the intracellular cavity into a valine. the functional conse- quence is a large increase in unbinding kinetics. how does each ‘‘wall’’ of the cavity contribute to the increase in unbinding kinetics of a single bound n-terminus? to address this question we made con- catenated shaker heterotetramers consisting of only one free n-terminus and a single isoleucine to valine mutation at position (i v), mimicking the rna editing site in humans and rodents. surprisingly, the rate of unbinding was the same for individual i v mutations in each wall; each corresponded to a decrease in binding energy of about . rt. in fact, the binding energy de- creased linearly as a function of the number of i v mutated subunits. these results suggest that despite being tethered to a particular subunit, the single in- activation particle has sufficient freedom to interact with position of each subunit with roughly equal probability. where does this freedom come from? it is expected that the inactivation gates enter the cavity through lateral ‘windows’, similarly to k þ . can our single tethered inactivation gate enter through each of the four windows of the protein? we will address this question by making individual cysteine mutations at each window and testing the inac- tivation gate’s binding kinetics after chemical modification. -pos board b gating interactions between the cytoplasmic t domain and pore of a kv channel brian urbani, manuel covarrubias. jefferson medical college of thomas jefferson university, philadelphia, pa, usa. whereas the gating roles of the voltage-sensing and pore domains of kv channels have been extensively investigated, much less is known about the mechanisms governing the regulation of gating by the cytoplasmic t domain. previous work from this lab strongly suggests that the kv . t domain un- dergoes conformational changes directly linked to gating (j. gen. physiol., : - , ); however, the structural basis of the communication between the activation gate and the t domain has remained elusive. to tackle this problem, we applied cysteine scanning mutagenesis, voltage- clamp electrophysiology, double mutant cycle analysis (dmca) and oxidizing reagents to probe specific interactions between the cytoplasmic t domain l helix, the s -s linker and s tail. the energetic impact of the mutations on activation gating is apparently small. by comparison, the energetic impact of the mutations on inactivation gating was significantly greater. dmca of k c(l )þa c(s ) revealed a significant interaction energy ( kcal/ mol), which suggests an interaction between k in the l helix and a in s . supporting this possibility, the currents induced by k c(l )þ a c(s ) are inhibited (~ % of control) by an oxidizing agent (tbuho ), whereas the single mutants are not; and the effect is reversed by the reducing agent dtt. these results indicate the formation of a disulfide bond between the interacting side chains, which is consistent with physical interaction between k (l ) and a (s ). overall, we conclude that regulation of inactivation gating by the t domain involves a physical interaction between the t l helix and the distal segment of s . supported by nih grant r ns (mc). -pos board b is the activation gate closed in kv channel closed-state inactivation? jeffrey d. fineberg, manuel covarrubias. thomas jefferson university, philadelphia, pa, usa. kv .x channel complexes including auxiliary subunits such as dpp -s and kchip undergo preferential closed-state inactivation (csi; baehring and covarrubias, , j physiol, . : - ; fineberg et al., , j gen physiol, in press). however, the molecular basis of csi in kv .x channels remains poorly understood. a key unanswered question of this problem is whether the channel’s activation is actually closed, as csi implies. we have previously proposed that csi results when the activated channel fails to open or simply prefers to close. this hypothesis specifically suggests that the intra- cellular activation gate may adopt a stable closed conformation, even under depolarized conditions that would initially favor the activated ‘‘up’’ state of the voltage sensors. to test this hypothesis, we are exploiting the trapping paradigm previously investigated by holmgren et al. to test the state of the intracellular activation gate ( , j gen physiol, : - ). essentially, if the activation gate closes behind a quaternary ammonium (qa) blocker inside the pore, the blocker cannot exit the pore; effectively, it is trapped. we are expressing the ternary kv . /i c channels (this mutation favors trap- ping) including dpp -s and kchip in xenopus oocytes. then, in the inside- out patch-clamp configuration, we are using a computer-controlled perfusion system to deliver the qa derivative decyltrimethylammonium bromide (c ) to the bath and probe the ability of the channel’s activation gate to trap c in the closed, open and inactivated states. preliminary results show that the trapping paradigm may yield an answer to the central question of this study. if the activation gate is indeed closed during csi, c trapping will only occur when the drug is applied to the conducting channel, but no trapping of c will be observed in the closed and inactivated states.

city university of ny, new york, ny, usa. quantum calculations on the open gate and the immediately surrounding re- gion of the kv . voltage gated potassium channel show that water adopts two conformations there, one when the ion is present, and another with no ion present. an energy minimum at the gate with no ion allows an ion to enter from the solution; from the gate it repels an ion in the channel pore cavity into the selectivity filter (essentially the ‘‘knock-on’’ mechanism). the pore cavity minimum can then be occupied by the ion moving from the gate minimum, leaving it available for anion from bulk, so the cycle continues. the arrange- ment of water, and the ion hydration, defines the gate energy minimum, and this in turn depends on the highly conserved prolines, especially p ( a pdb numbering), in the pvpv sequence in the gate. absent an energy minimum at the gate an ion entering from solution would be repelled back into solution by the ion in the cavity. furthermore, the ion remains hydrated by water molecules, at least more than in bulk, as it passes through the gate, based on optimizations with the ion at three different positions: ) at the gate position nearest p ) å above ) å below, this position. the open gate maintains very nearly the same protein atom positions throughout. additional calculations will be required to determine the exact interaction en- ergy with an ion in the cavity, and the amount of water that is present in the cavity. optimizations of the system configuration were done at hf/ - gsp level, with atoms ( with the ion). energy was determined using both b lyp/ - g* and bvp / - g*, but the system was too large for free en- ergy determination. -pos board b water structure at the potassium channel gate: the importance of the prolines in the pvpv sequence, as shown by computational mutations, and the role of a histidine in gating alisher m. kariev, michael e. green. city college of the city university of ny, new york, ny, usa. conservation of the pvpv sequence at the potassium channel gate has not been well understood. quantum computations (optimization at hf/ - gsp level) of the gate of the kv . channel that are presented here show that the proline-proline distances (ring atoms) are preserved as the ion moves through the gate. this calculation is supplemented by mutating one of the prolines to valine (p v, a pdb numbering for all residues in this abstract) in the computation, producing a pvvv sequence. water structure changed dramati- cally, as the protein backbone moved inward nearly å, effectively closing the channel; the proline ring n-n distance between diagonally opposite pro- lines dropped from . å (distance from optimization: x-ray distance = . å) to . å, too small to allow passage of a hydrated k þ . this suggests that the prolines play a key structural role, modulating both protein and water structure. furthermore, protonation of h may close the channel. protonation of this histidine shows it moving toward the gate by about å, which should close the gate electrostatically, while deprotonation opens the gate. protonation was calculated with two added protons, the other being accepted by e of the t intracellular moiety. when deprotonated, the histidine does not move as much as å from the x-ray position in the optimization, and is linked to e ; this accounts for the known importance of the t segment in gating. e , also of t , could accept a third proton. there is a salt bridge structure including these residues similar to the one occupying a key position in the pro- ton pathway in the hv channel. access constraints and binding energetics of a potassium channel inactivation gate gating interactions between the cytoplasmic t domain and pore of a kv channel is

dinner president john f. kennedy hosted for american nobel prize winners in . “i think,” kennedy told his guests, “this is the most extraordinary collection of talent, of human knowledge, that has ever been gathered together at the white house—with the possible exception of when thomas jefferson dined alone.” unlike some of the tales we heard at our parents’ knee, this one seems to square with the historical record. the anecdote came to mind after watching an exchange be- tween host tom brokaw and president-elect barack obama on the dec. edition of nbc news’ “meet the press.” it was just a fleeting comment near the close of the hour-long interview, and passed so quickly i almost missed it, sandwiched as it was between two higher-profile items: the nomination of gen. eric shinseki to head the veterans administration and mr. obama’s pledge that, despite his own difficulty quitting smoking, he will see that no-smoking rules are obeyed in his white house. here is an edited transcript: brokaw: ...let me ask you as we conclude this program this morning about whether you and michelle have had any discussions about the impact that you’re going to have on this country in other ways besides international and domestic policies… who are the kinds of artists that you would like to bring to the white house? obama: …[ w ] e have thought about this because part of what we want to do is to open up the white house and… remind people…this is the people’s house. there is an incredible bully pulpit to be used when it comes to, for example, education. yes, we’re going to have an education policy. yes, we’re going to be putting more money into school construction. but, ultimately, we want to talk about parents reading to their kids. we want to invite kids from local schools into the white house. when it comes to sci- ence, elevating science once again, and having lectures in the white house where people are talking about traveling to the stars or breaking down atoms, inspiring our youth to get a sense of what discovery is all about. thinking about the diversity of our culture and, and inviting jazz musicians and classical musicians and poetry readings in the white house so that, once again, we appreciate this incredible tapestry that’s america… [o] ur art and our culture, our science…that’s the essence of what makes america special…and we want to project that as much as possible in the white house. scientific lectures at the white house. if i used exclama- tion points, i’d use one here. how long has it been since we thought of a president actually embracing and enjoying the challenge of science? are we really facing a time when american leadership once again accepts scientific inquiry as an integral part of our culture, and not an enemy of it? with regard to whom, exactly, mr. obama should invite to the white house, we have some obvious choices. the new president should hear rita colwell’s ( university of maryland and johns hopkins university) “climate, oceans, infectious disease, and human health: the saga of cholera.” [ we heard her in october at columbia university’s annual presidential lecture, and wrote about it for the online component of our december issue ( ). he and his administration would also benefit from visits by any of the participants in the extraordinary james l. waters symposium, including leroy hood ( institute for systems biology, seattle, wa) talk- ing about p medicine ( p stands for “predictive, preventive, personalized, and participatory” ), george church ( harvard university) discussing the means and applications of high- speed, low-cost individual sequencing, or richard wilson ( washington university in st. louis) explaining crop plant genomics or the history of the human genome. better yet, we would like to hear our readers’ suggestions for the white house lectures. so please post your suggestions on the “to the editor” section at the bottom of the biotechniques molecular biology forums page ( ). if you’re shy, write directly to douglas.mccormick@ informausa.com. tell us whom the people of the united states should invite to lecture at the people’s house, what we should ask them to talk about, and why the president should listen. references . mccormick, d. . washed in a microbial sea. biotechniques vol. , no. : ( dec. ), www. biotechniques.com . “to the editor,”

m., georesearch department, earth museum, toledo ave. n., robbinsdale, mn , u.s.a. perhaps unlike any other field of science, paleontology is dependent upon the contributions of common everyday people. indeed, in many cases formal academic training is completely immaterial to making great scientific discoveries in paleontology. historically, earth science is replete with giants who had little or no academic background at all. in addition, the vast number of fossils in the world's institutions were discovered by amateurs and commercial collectors, not degreed professionals. the history of commercial fossil collecting is long and honorable. it began long before the advent of geologic sciences or such things as museums. europeans have commercially traded fossils for centuries. before the u.s. was a nation fossils were collected and bartered by indigenous peoples that lived here. even our founding fathers supported the fossil trade. thomas jefferson was a naturalist who bought and sold fossils on a regular basis. the contributions of commercial fossil collecting have not been small. every specimen of archaeopteryx, arguably one of the most important fossil species known, is the result of collection by commercial groups. the largest, most complete tyrannosaurus rex was found by a commercial party which, incidentally has discovered more t. rex specimens than any other group, public or private. even jack horner has a commercial shop to thank for his discovery of baby dinosaurs that launched him to the front of dinosaur science. and what paleontologist today hasn't held in their hand a fossil specimen from wards or carolina biological supply during their early education? or entered a limestone quarry, gravel pit, or coal mine to search for fossils under the auspices of the commercial owner? who will provide those specimens or access to them if commerce in fossils is restricted? paleontology is best served in a spirit of working together. cooperation between land owners and fos.sil collectors, government and industry, academics and amateurs, public institutions and private enterprise is all needed to the continued vitality of this science. there is no reason au concerned parties cannot work together and promote paleontology like never before. july-august • vol. , no. family medicine brief reports r acial and ethnic disparities in health persist in the unit- ed states. - these dispari- ties also exist in self-perception of health. african americans (aa) were less likely to describe themselves as overweight versus whites, were par- ticularly less likely to adopt healthy weight-related attitudes and behav- iors, and have worse obesity out- comes. health-specific self-efficacy is a strong predictor of health behav- iors. , recent research has shown efficacy for targeted, community- based interventions resulting in re- duced weight and cardiovascular risk factors for aa women in urban communities. , tailoring a weight- loss intervention to specific popula- tions may be a reasonable approach to reducing chronic disease in these groups. the stephen klein wellness cen- ter is a family medicine residency- affiliated federally qualified health center (fqhc) in north philadel- phia serving a predominantly aa community. the fqhc’s target population was determined to have significantly poorer health than phil- adelphia residents overall. sociocultural factors play an im- portant, positive role in exercise ad- herence ; therefore, a community needs survey was performed and identified nutrition, exercise, and physical activity (pa) as very impor- tant aspects of health and wellness to community members. respon- dents desired aerobic activities, spe- cifically indicating “urban” or “soul” (synchronized, choreographed, so- cial dance with cultural roots in af- rica and the caribbean) line dancing classes, , confirmed by additional community meetings. this study evaluated how partici- pation in a community-tailored, soul line dancing class with nutrition ed- ucation correlates with changes in background and objectives: the population surrounding an urban federally qualified health center (fqhc) in philadelphia has poorer health than philadelphia overall. community residents identified aerobics and dance classes as very important services or programs that an fqhc might provide. we sought to measure the impact of participation in a resident physician-led, patient-centered fitness and nutrition class on participants’ attitudes, knowl- edge, and self-efficacy regarding their health. methods: an urban line dancing class and brief healthy eating intervention for adults was held at a ymca adjacent to a residency-affiliated fqhc weekly for weeks. pre/postsurveys were administered to assess attitudes and con- fidence toward physical activity and healthy lifestyles. results: participants’ self-assessment of health and levels of physical activ- ity improved. confidence in performing everyday activities, doing regular exer- cise and exercising without making symptoms worse increased. a significant decrease in participants’ physical activity gratification was observed. partici- pants’ confidence improved in reading food labels for health, but confidence in eating a balanced diet did not improve. conclusions: a resident-led fitness and nutrition class, tailored to per- ceived community needs, generated significant interest and sustained par- ticipation. this pilot study furthered development of community infrastructure addressing health, nutrition, and overall fitness, and the results reflect oppor- tunities and challenges of engaging communities in physical fitness.

this approach could also uncover barriers to partic- ipation in the class. finally, relation- ship development with participants and the impact of the study on resi- dent attitudes and behaviors with table : health-related domains: pre- and postsurvey mean responses health-related domain survey item pre post significance ( -tailed) grouped significance self-assessment of health overall healtha . . . p=. physical fitnessa . . . ability to perform adlb . . physical activity enjoymentc pleasurable . . . p=.   fun . . . gratifying . . . stimulating . . . refreshing . . physical activity confidence levelsd muscle strength and flexibility . . . p=. aerobic exercise . . . exercise without increased symptoms . . . abilities to consume a healthy dietd find healthy food p=. eat a balanced diet . . . understand fiber content in food . . . read food labels . . . consume recommended water intake . . . abbreviation: adl, activities of daily living. a self-assessment of health questions (rate overall health) and (rate physical fitness): excellent= , very good= , good= , fair= , poor= . b self-assessment of health question (ability to carry out adl): completely= , mostly= , moderately= , a little= , not at all= . c physical activity enjoyment: extremely “x”= , very “x”= , moderately “x”= , slightly “x”= , not at all “x”= . d physical activity confidence and abilities to consume health diet: completely confident= , fairly confident= , somewhat confident= , slightly confident= , not at all confident= . july-august • vol. , no. family medicine brief reports underserved populations are also two important factors that could be addressed in future studies. this project identified a commu- nity partnership with potential to improve the community’s ability to address health, nutrition, and overall fitness. the class increased ymca memberships and the number of pa- tients receiving primary care at the fqhc. we encourage this fqhc and ymca partnership to be mod- eled by others to foster active en- gagement in health and well-being. acknowledgments: the authors thank the women’s board of thomas jefferson uni- versity for financial support of this pilot in- tervention, as well as the faculty and staff at the ymca, tjuh and skwc for support of the project, assistance with recruitment, and guidance with analysis. this study was presented as “development of a community-tailored, resident-led, fitness and healthy eating intervention at an urban federally qualified health center,” at the society of teachers of family medicine annual spring conference, may - , , san diego, ca. corresponding author: address corre- spondence to dr krys foster, walnut st, suite , philadelphia, pa . - - . fax: - - . references . mensah ga, mokdad ah, ford es, greenlund kj, croft jb. state of disparities in cardiovas- cular health in the united states. circulation. ;

and kchip a kid directly interacts with the t domain to relieve the stabilization, leading to facilitation of csi and inhibition of channel function. -plat two-in-one: activation and inactivation at the intracellular gate of a kv channel manuel covarrubias , jeffrey d. fineberg . neuroscience, jefferson medical college of thomas jefferson university, philadelphia, pa, usa, physiology and molecular biophysics, jefferson medical college of thomas jefferson university, philadelphia, pa, usa. n-type and p/c-type inactivation are firmly established mechanisms of inac- tivation in voltage-gated kþ (kv channels). however, kv .x channel com- plexes, which undergo fast preferential closed-state inactivation (csi; fineberg et al., , jgp . : - ), appear to use a distinct but un- known inactivation mechanism. previously, we hypothesized that a weak interaction between the voltage sensing domain and the intracellular activa- tion gate underlies csi (bähring & covarrubias, , j physiol : - ). thus, csi is essentially governed by the intracellular activation gate, which fails to open and adopts an inactivated conformation. to directly test this hypothesis, we investigated the heterologously expressed kv . ternary channel complex including accessory subunits kchip and dpp , and ex- ploited the ‘‘trap-door’’ paradigm of the activation gate. the results show that kv . inactivation traps intracellularly applied quaternary ammonium blockers (btbua and tbua) inside the channel’s pore. the trapped blockers can only escape if the channels are opened again by subsequent depolariza- tions. by contrast, inactivation cannot trap tea, whose binding kinetics is faster than that of channel gating. moreover, under identical conditions, a shaker kv channel (shb-t k) known to exhibit fast p/c-type inactivation cannot trap btbua. these findings conclusively suggest that the intracellular activation gate of the kv . ternary channel complex plays a novel dual role, controlling both activation and inactivation. supported in part by nih grant r ns (mc). -plat development and validation studies of universal pharmacophore models for herg channel openers serdar durdagi , , matthew patterson , sergei y. noskov . department of biophysics, bahcesehir university, faculty of medicine, istanbul, turkey, biological sciences, institute for biocomplexity and informatics, university of calgary, calgary, ab, canada. the intra-cavitary drug blockade of herg channel, a common off-target for many drugs, have been extensively studied both experimentally and theoreti- cally. structurally diverse ligands inadvertent blockade of rapid component of delayed rectifying kþ currents are potentially pro-arrhythmic and may lead to drug-induced long qt syndrome-lqts. there are a number of natural strategies for rational drug design; one dubbed the ‘‘passive’’ approach avoids block of herg whereas the ‘‘proactive’’ strategy designs treatments to acti- vate the channel. while ‘‘passive’’ approach has been developed for decades, studies of structural mechanisms of herg channel activation by small mole- cules are truly novel. accordingly, design of the herg openers or current ac- tivators may offer a momentum for modern anti-arrhythmia drug development. significant number of small molecules with capacity for herg activation was identified in mandatory herg screens. to establish possible correlation be- tween activators structure and reactivity, we attempted to construct a universal pharmacophore model for herg channel openers using phase protocol. the biochemical data on kþ channel activators are used in training and test sets. these compounds span a wide range of structurally different chemotypes with ~ ^ -fold variances in binding affinity, which is sufficient for statistically sound model. a developed five sites aahhr (a, hydrogen-bond accepting, h, hydrophobic, r, aromatic) pharmacophore model has showed reasonable high statistical results compared to other constructed models and was selected for steric and electrostatic contour maps analysis. the predictive power of the model was also tested with external test-set (as true unknowns) compounds. pharmacophore model is also combined with previously developed receptor- based homology model of herg k channel and novel activators are generated and screened. the developed ligand-based models may serve as a basis for the synthesis of novel potential therapeutic herg activators. -plat n-terminal regulation of herg kd channel deactivation steven j. thomson, angela hansen, michael c. sanguinetti. nora eccles harrison cardiovascular research and training institute, university of utah, salt lake city, ut, usa. slow deactivation of herg (kv . ) potassium channels maintains ikr dur- ing final repolarization of the cardiac action potential and opposes asynchro- nous early depolarization. inherited point mutations in herg that accelerate deactivation of ikr cause long qt syndrome (lqts), a disorder of ventricular repolarization that increases the risk of lethal cardiac arrhythmia. the intracellular n-terminal domain of herg is known to be essential for slow deactivation. deletion of the entire (~ residues) or just the initial residues of the n-terminus accelerates deactivation -fold. the same effect is achieved by neutralization of the charged residues, arg or arg . how many of the n-termini are required to slow channel deactivation is unknown. herg , like other kv channels, is a homotetramer. by repeatedly linking the c-terminal of one subunit to the n-terminal of the next subunit we constructed concatenated herg tetramers. a variety of homomeric and heteromeric concatenated tetramers were characterized (i.e., wtn/r a:r a( -n); where n = to ). the concatenated channel containing a single r a/r a subunit and wild-type subunits deactivated as fast as the concatenated channel con- taining only r a/r a subunits. the lqts-associated mutation r q, located in the n-terminal of herg was also studied. again, a concatenated tetramer containing a single mutant subunit deactivated as fast as channels with r q mutations in all four subunits. our results show that all n-termini are required to mediate slow deactivation in wild-type herg channels. -plat lipid affinity to the voltage-gated potassium channel kvap elise faure , christine thompson , rikard blunck , . physiology, université de montréal, géprom, montréal, qc, canada, physique, université de montréal, géprom, montréal, qc, canada. voltage-gated potassium channels (kv) are formed by a central conducting pore surrounded by four voltage sensor domains. functional studies have re- vealed that biophysical properties of lipid molecules in the channels environ- ment can have strong effects on the activity of kv channels. here, we investigated the influence of different lipids as well as their affinity to kvap channels. we carried out electrophysiology measurements by fusing vesicles containing purified channels into planar lipid bilayers with varied lipid compo- sitions. we found that kvap properties are mainly determined by the lipid a-type kv channel closed-state inactivation is modulated by the tetramerization domain interacting with auxilary kchip a two-in-one: activation and inactivation at the intracellular gate of a kv channel development and validation studies of universal pharmacophore models for herg channel openers n-terminal regulation of herg k+ channel deactivation lipid affinity to the voltage-gated potassium channel kvap i n t e r - a m e r i c a n n o t e s chairman of the conference on latin american history of the american historical association. j. preston moore of louisiana state university, author of the cabildo in peru under the hapsburgs (durham, n . c , ), is at present in peru studying municipal documentation of the eighteenth century. e m i l i o rodriguez demorizi has been named rector of the university of santo domingo. robert c. mead of the university of connecticut is the new director of the review hispania, the official journal of the association of professors of spanish and portuguese of the united states. philip c. brooks of the national archives, san francisco branch, has been appointed director of the new truman library in independence, missouri. r e c e n t d e a t h s v i t o alessio robles died in mexico city in june, , at the age of years. h e was born in saltillo, coahuila, and concentrated his historical studies in the northern provinces of mexico, in particular, coahuila and texas. his coahuila y texas en la epoca colonial (mexico, ) is one of the most outstanding works to come from his pen. alessio robles edited editions of many works of fundamental importance for the history of northern mexico, such works as the viaje de indios and the diario de nuevo mexico of fray agustin de morfi (mexico, );

however, julian p. boyd disagrees, stating that "there is not a shred of evidence to support such a charge." fortunately, these are the only serious gaps in the extensive accumulation of man- uscript materials which jefferson left when he died on july , , exactly fifty years after the declaration of independence was adopted. three months before his death, jefferson executed a will which bore the follow- ing codicil: "my papers of business going of course to him [his grandson, thomas jefferson randolph] as my executor, all others of a literary or other character i give to him as of his own property." sarah nicholas randolph, in her charming and informative work the domestic life of thomas jefferson, has noted jefferson's relationship with his grandson: mr. jefferson had found the cares of his large estates too great a burden for him to carry in his advancing years, and gladly handed them over into the hands of the young grandson, in whose skill and energy he expresses such perfect confidence. . . . until the day of jefferson's jefferson to page, february , ;

and, in , lee told washington that jefferson was involved in intrigue against his administration. jefferson's correspondence clearly indicates that he knew of and resented lee's machinations. in light-horse harry's son, henry lee, proceeded to publish the avowedly partisan observations on the writings of thomas jefferson, which did little to remove the stain from his father's escutcheon. the vivid partisanship which thus enveloped the first publication of jefferson's correspondence led thomas jefferson randolph to permit the political economist and author george tucker ( - ) to see "all the letters written" by jefferson so that he could prepare an impartial rebuttal to lee's work. as a youth, tucker had been sent from his native bermuda to the care of his distant relative, st. george tucker ( - ), who had succeeded jefferson's mentor, george wythe, as pro- fessor of law at the college of william and mary. the young man had, therefore, come to maturity among the leading antifederalists in the jefferson circle. in spite of this pro-jeffersonian background, tucker performed extensive independent research, held many conferences with james madison, and used a "selection of such letters and papers, never before published, as were thought to throw light on mr. jefferson's character." the result of tucker's research was the life of thomas sarah n. randolph, the domestic life of thomas jefferson ( ;

to comply would greatly impair their value and i have felt myself reluctantly compelled to decline a compliance. my contemplation is to dispose of the whole in mass where the[y] would be accessible to every one. randolph kept the jefferson collection intact because he was aware of contemporaneous sales of the george washington papers ( ) and the james madison papers ( ) to the government. later criticism of the incompleteness of the papers mrs. madison had sold to the government led secretary of state james buchanan to admonish randolph to include both public and private papers in the sale. in due course, the appropriation act of august , , providing for the civil and diplomatic expenses of the government for the fiscal year , contained the following item: for paying to thomas jefferson randolph, executor of thomas jefferson, deceased, the sum of twenty thousand dollars, for all the papers and manuscripts of the said thomas jefferson: provided, that said t.j. randolph shall deposit all the said papers and manuscripts of a public nature in the state department, and execute a conveyance thereof to the united states. t h e papers were deposited by randolph at the department of state for exam- ination, in order that the private papers might be separated from the public and returned to the family. shortly thereafter, in , randolph wrote a particularly informative description of the state of his grandfather's papers at the time of their sale to die federal government in : the letters written by mr. jefferson are all arranged together in chronological order. the pa- pers, documents, official correspondence, notes of transactions while secretary of state to gen washington, are bound in three volumes of marbled paper, marked a. b. c : the letters received are in three series alphabetically arranged—the first, received during his residence in paris;

that he would arbi- trarily divide the jeffersonian manuscripts into five series; that the personal papers would remain unexamined until ; that the federal government would fail to purchase thousands of manuscripts offered to it by other descendants at bargain pri- ces; that there would be a reappearance in of enough jeffersonian manuscripts to fill nineteen additional volumes; that major segments of jefferson's papers would be added to the library of congress's collections as late as ; or that defin- itive publication of the third president's outgoing and incoming correspondence would not commence until . randolph's letter, therefore, takes on retrospective importance in confirmation of the archival integrity jefferson main- tained throughout his lifetime in the control of his priceless collection of manu- scripts. it was this integrity which was to desert the collection, for a variety of rea- sons, for over a century after its receipt in the department of state by secretary james buchanan. on march , , virginia congressman james murray mason, of the joint committee on the library, asked henry augustine washington, of the college of william and mary, to edit the papers of thomas jefferson for publication by the government. as a grandson of george mason, congressman mason believed that it is of great importance to virginia that this duty should be performed by one of her own citizens whose integrity c capacity may be relied on, that no injustice shall be done to the fame of mr jefferson. the mason letter clearly indicates that only material deemed of a "public" nature was to be selected. further, "it is not expected or desired that any editorial matter should be incorporated." on july , , professor washington had the jefferson papers delivered to him in a room set aside for him in the department of state, where he worked on them for fifty-nine days at $ . per day. however, the most singular point of agreement, which was arrived at after some uneasiness on the part of the joint committee on the library, was the removal of the jefferson manu- scripts from the district of columbia to williamsburg. washington was deter- mined to maintain his full schedule of academic duties at the college of william and mary, and by late autumn of he had persuaded the committee members to agree to the mass removal. once the papers were in williamsburg, washington speedily set to work copying and collating the material. between october and august , he worked t. j. randolph to h. a. washington, august , ;

the nine volumes of the writings of thomas jefferson were published in - . in addi- tion to editing jefferson's papers for publication, however, washington had also agreed "to select all papers worthy of preservation among the national archives [at the state department], & arrange & index the same." on december , , assis- tant librarian of congress edward stelle wrote to inquire in behalf of the joint committee as to the length, duration, and cost of the publishing project. wash- ington temporized on the exact length, number of volumes, and possible costs of the publication of the letters and then summed u p his work on selecting and binding the papers for preservation: and, in discharge of . . . my duty, some one hundred & twenty five volumes of manuscripts have been selected, arranged, indexed, c are now ready for the hands of the binder—leaving in my possession a mass of refuse matter nearly twice as large as that which has been selected j o i n t committee account book with library, p p . a n d ;

this would be suspected only in , when william k. bixby purchased , items of jefferson correspondence from a descendant of the two editors, george tucker and henry a. washington, a purchase to be discussed later. t h e selection of the private papers from the u n b o u n d manuscripts was apparently overlooked at the state department until , when thomas jefferson randolph wrote to complain to secretary of state hamilton fish: prior to the late rebellion i sold to the government, the letters and papers of president jefferson. . . . on the delivery of those papers, mr. buchanan, then secretary of state, required me to deliver his whole papers public and private: those which came under the purview of the act [august , ] and those which did not; submitting to a committee (i think the library committee) to determine. mr. buchanan after the delivery gave himself no further concern about it. it became impos- sible to get the committee to act, thus i lost private family papers of no use to any save mr jeffersons family, and obviously not included in the terms of the act. these if my memory does not deceive were contained in three square pine boxes marked private papers. these papers i desire to reclaim and you sir would lay me under great obligation could you facilitate this object. secretary fish replied to randolph on november , , that the act of august , , appeared to him "ambiguous" and also that an examination of the department's records disclosed nothing "to show mr. buchanan ever contemplated the return of any portion of the papers." fish closed by saying he had no legal au- thority to act, and that only congress could effect such a restitution. h. a. washington to edward stelle, january , ;

and, finally, his valiant attempt in to convince professor washington to honor jef- ferson's original intentions in the preservation of his priceless collection. on february , , congressman daniel w. voorhees called the attention of the joint committee to the application of sarah n. randolph of baltimore to reedit the works of jefferson, which she said were improperly edited and, in their pub- lished form, "very inaccurate." t h e committee thereupon invited miss randolph to appear on march , . t h e witness cited numerous errors in professor wash- ington's nine volumes, including omissions, inaccuracies, neglect, and ignorance, not to mention "tampering" with the manuscripts. in addition to preparing a new, correct, and thorough edition, miss randolph proposed to include documents in her family's possession which would "throw much light upon the private and pub- lic life of the great statesman, and present him in many phases of life, heretofore unknown and therefore all the more interesting to the world." after the interested committee heard miss randolph's presentation, it directed librarian spofford to report to the committee at their next meeting. for his report at the march , , meeting, spofford prepared a four-page mem- orandum which largely supported miss randolph's contentions of the shortcom- ings of professor washington's work. additionally, spofford pointed out that the original letterpress copies "are gradually fading, and may hereafter become inde- cipherable." spofford's most devastating criticism was reserved for his summa- tion: the deficiencies of this edition are so great as to impair, and in some cases to destroy its value as an index to true opinions of mr. jefferson, and to his relation to the men and events of his time. . . . the fact remains that the writings of one of the foremost statesmen in american history have been given to the world in a most incomplete form, omitting far more than they contain. after hearing spofford's sobering report, the joint committee appeared to be con- vinced of the necessity of a new edition of jefferson's writings to be prepared by miss randolph under spofford's general direction. on april , , and again on january , , the joint committee came out in favor of sponsoring a new and comprehensive edition of jefferson's "correspondence sent and received," for prep- aration of which miss randolph was to receive $ , a year. however, by the committee was also considering the purchase of the papers in miss randolph's possession, none of which were duplicated in the state department collection. t h e debate in congress over the purchase continued for several years and in the mean- time the editorial project was shunted aside. sarah randolph died on april , , leaving the papers to her sister, caroline ramsey randolph. t h e joint committee had recognized the value of reuniting the public and private collections of jeffer- extracts, minutes of the joint committee, p. ;

(lexington: university press of kentucky, . xviii, pp. cloth $ . , isbn - - - - .) kentucky’s first tourist attraction, big bone lick has long deserved a mod- ern account such as stanley hedeen provides. professor emeritus of biology at xavier university, hedeen does a fine job of interpreting the history and significance of the prehistoric and historic salt lick aptly termed “the cradle of american paleontology.” well-grounded in history, geology, and vertebrate paleontology, the au- thor for the most part ably deals with a historical problem compounded by a plethora of obscure and widely scattered references; but in some respects his study supplements rather than supplants the work of the same title by the indefatigable willard rouse jillson (published by the original big bone lick association). hedeen does clarify jillson’s mistaken date for charles de longueuil’s expedition and provides previously unknown nineteenth-century newspaper references. his account is more readable and benefits from more recent advances in our understanding of local geomorphology, paleoecology, and vertebrate taxonomy. he incorporates much unpublished or “underpublished” recent research. hedeen’s account is comprehensive but not quite complete, for both he and jillson omit two significant references to early visitors. in capt. william harrod, hastening to join col. john bowman’s expedition against the shawnee indians of ohio, encountered a group of men transporting a canoe-load of specimens from big bone lick to redstone old fort. some . “bowman’s expedition against chillicothe, may‒june, ,” ohio archaeological and historical publications ( ): ‒ . bo ok reviews of these men joined harrod and bowman on the unsuccessful ohio foray, and subsequently “capt. wm. harrod, with others, went up the ohio to red stone in the two keel boats &c. and took along several bones & tusks got at the big bone lick.” what became of these specimens remains unknown, but this was an important early effort at “mining” the deposits at big bone. similarly, neither jillson nor hedeen mentions thomas rodney’s well-doc- umented stop there on october , , less than a week after meriwether lewis’s collecting visit for thomas jefferson. rodney not only took measure- ments of several of the remaining fossil bones but speculated (incorrectly) that no animals larger than bison ever existed there, larger bones being “only fossil concretions.” rodney himself collected a mastodon tooth and a tusk fragment, but these were lost when his boat sank at natchez. curiously, hedeen merely reproduces without explanation a photograph of three paleo-indian points “collected” at big bone lick. elsewhere, he has written that these were discovered in the lowest level of the big bone de- posits during william clark’s excavations for thomas jefferson and are “now likely” housed at the cincinnati museum center. the significance of associated paleo-indian artifacts and megafauna at big bone lick should certainly be acknowledged but so too should the considerable debate exist- ing about the precise provenance and pedigree of these artifacts. such strictures aside, this book provides ample context for the present big bone lick state park museum and should remain a standard resource for many years. ja m e s l . m u r p h y the ohio state university mennonites, amish, and the american civil war. by james o. lehman and steven m. nolt.

napoleon’s atlantic: the impact of napoleonic empire in the atlantic world. christophe belaubre, jordana dym & john savage (eds.). leiden, the neth- erlands: brill, . xvi + pp. (cloth € . ) napoleon’s atlantic is the english translation of the proceedings of a sym- posium entitled “l’atlantique napoléonien” organized at the university of toulouse-le mirail in , which were first published in french in . as the french title—napoléon et les amériques: histoire atlantique et empire napoléonien—more accurately conveys, the book’s scope is not fully atlantic: apart from a mention of the egyptian campaign in the introduc- tion, africa is nowhere, and europe does not occupy center stage. instead, the collected essays focus on the impact of the napoleonic empire on the americas, already a fully legitimate and very ambitious project. napoleonic studies in france have been largely limited to the impact of the napoleonic empire in europe. in the same way, historians of latin american independence movements who are increasingly exploring the connections between the various revolutions in the atlantic world have paid little attention in recent times to the specific influence exercised by the napoleonic regime. thus, the book aims at changing both the spatial and the chronological framework of napoleonic studies and of atlantic history in the era of revolutions. it is also an attempt at connecting the two fields. the book’s title is also misleading in another way, since the collection of fourteen essays does not cover the whole napoleonic period, but focuses on the decades following , after napoleon’s imperial coronation and the quasi-disappearance of the french atlantic empire with the failure of the leclerc expedition, the louisiana purchase, and haitian indepen- dence. the extension of the chronological framework beyond , intended to demonstrate that the impact of the napoleonic regime endured after his fall, has been made to the detriment of the consulate. the book’s napole- onic empire thus has no colonial or postcolonial dimension: no chapter is devoted to saint-domingue/haiti, and the french lesser antilles are only briefly taken into account in john savage’s contribution. rather than “the direct and indirect consequences of france’s substan- tial retreat from an atlantic presence after / ” (p. ), the book is con- cerned above all with the direct and indirect consequences outside europe of the french invasion of the iberian peninsula, and with the influence of the napoleonic regime on latin american independence movements ©

not included the two chapters which have nothing to do with these questions: luca codignila’s contribution on the reactions of the “north atlantic catholic community” to napoleon’s policy toward the church and the pope, and jean-marc olivier’s essay on jean-baptiste ber- nadotte, who refused his appointment as governor of louisiana before the colony was sold to thomas jefferson. most of the other essays deal with brazil and spanish america or its (for- mer) borderlands. there is a strong emphasis on the greater caribbean, with half the contributions focusing on central america, gran colombia, cuba, louisiana, and texas. topics addressed by this collection of essays include the motivations of sugar planters in cuba or of indiano bureaucrats in spain to join or not to join napoleon’s side (dominique goncalvès and víctor peralta ruiz); the reporting of latin american events in the french press (felipe angulo jaramillo); the fear of french emissaries in central america (timothy hawkins); the political activism and cultural influence of french expatriates after napoleon’s fall (christophe beleaubre, rafe blaufarb, lilia moritz schwartz, and roderick barman); the intrusion of the militaries, following napoleon’s model, in the political field (mónica ricketts); and the impact of the napoleonic code (john savage). their insistence on the circulation of people, information, and ideas complies with atlantic his- tory’s methodology. apart from contributions by matt childs and nathalie dessens on the saint-domingue refugees’ expulsion from cuba and their relocation on louisiana, however, they all focus on white elites. in fact, childs’s essay on the little-known riots of free people of color against french émigrés in cuba in is one of the two best chapters of the book. it deconstructs the narratives by the state and the church to explain why the rioters who returned stolen goods were not prosecuted. the two institutions interpreted the event differently, but “both accounts deemphasized the role played by people of color in the riots and attempted to criminalize what might have developed into broader political activity” (p. ). if the rioters’ motivations are impossible to recover with certainty, the fact that one of their leaders later participated in the aponte rebellion in could be a sign of a real political and revolutionary agenda. another fascinating chapter is the one by john savage on the impact of napoleonic laws in the nineteenth-century atlantic world. drawing mostly on the two cases of gran colombia and louisiana, but alluding to chile, downloaded from brill.com / / : : am via free access book reviews argentina, haiti, and canada, savage explores the various domestic and international motivations in the recourse to the napoleonic legal model, emphasizing rupture with the colonial past and state consolidation. he also demonstrates that the adoption of napoleon’s civil code implied a process of accommodation initially and over time to fit the local political agendas and social and economic situations, especially regarding property, including property in humans. thus, far from being only the vehicle of lib- eral ideas, the napoleonic code in its atlantic expansion was also an instru- ment of imperial designs. globally, the book is an interesting attempt to draw attention to some neglected transatlantic dynamics in the late eighteenth and early nine- teenth centuries. it should be recommended to graduate students and scholars interested in napoleonic empire, atlantic revolutions, latin american independence movements, and caribbean studies. cécile vidal École des hautes Études en sciences sociales, centre d’Études nord-américaines paris, france cecile.vidal@ehess.fr downloaded from brill.com / / : : am via free access the teacher reordering american constitutional law teaching* scott d. gerber, college of william and mary constitutional law is the corner- stone of an undergraduate public law curriculum. political scientists will therefore want to teach consti- tutional law in the most effective manner possible. to that end, there is a welcome trend to offer consti- tutional law as a two-semester se- quence, a trend reflected by text authors and publishers who are in- creasingly dividing their constitu- tional law texts into two parts (mezey , ). i say welcome trend because, as anyone who has taught constitutional law knows, there is too much material to cover adequately in one semester. traditional constitutional law teaching: powers first invariably, constitutional law courses begin with constitutional powers issues: the origins and scope of judicial review, congress and the development of national power, the powers of the presi- dency, the modern administrative state, the states and american fed- eralism, and representation, voting, and electoral politics. in two-se- mester courses, these issues are addressed in the fall. in one-semes- ter courses, they are covered in the first part of the semester. after the powers issues have been addressed, attention is then turned to constitutional rights is- sues: property rights and economic liberty, freedom of expression, as- sembly, and association, freedom of the press, religious liberty and church-state relations, criminal jus- tice, personal autonomy and pri- vacy, and equal protection. in two- semester courses, rights issues are addressed in the spring. in one- semester courses, they are covered in the second part of the semester. the rationale for teaching consti- tutional powers before constitu- tional rights seems to be, first, that the bill of rights and the four- teenth amendment, the bases for the vast majority of rights ques- tions, were not part of the original constitution and, second, that stu- dents need a foundation in constitu- tional powers before they can un- derstand constitutional rights. in the spirit of more effective teach- ing, i would like to suggest that undergraduate teachers reverse the order in which constitutional law is taught. although this suggestion may strike many traditionalists as heresy, it has proved to be an ef- fective pedogogical technique in my courses. in fact, i have gone so far as to require the constitutional rights course as a prerequisite for the constitutional powers course. reordering constitutional law teaching: rights first the justification for reordering constitutional law teaching is sim- ple: students learn the material bet- ter if rights issues are taught first. this is because constitutional rights questions are more intuitive to stu- dents than constitutional powers questions. the american people— undergraduate students included— are imbued with the idea that indi- viduals have rights, an idea that is at the heart of the american politi- cal tradition. "we hold these truths to be self-evident," thomas jefferson wrote in the declaration of independence, "that all men are created equal, that they are en- dowed by their creator with certain unalienable rights; that among these are life, liberty and the pur- suit of happiness." with respect to constitutional law specifically, although for much of american history the supreme court's docket was dominated by powers questions—marbury v. madison ( ), m'culloch v. maryland ( ), gibbons v. ogden ( ), cooley v. board of wardens ( ), united states v. e.c. knight company ( ), and a.l.a. schechter poultry corpora- tion v. united states ( ), to name but a few of the classic cas- es—that changed in when the court, under the threat of president franklin d. roosevelt's infamous "court-packing" plan, stopped striking down the new deal and redirected its attention to protect- ing civil rights and liberties. in- deed, ever since the "switch-in- time-that-saved-nine," rights questions have far outnumbered powers questions on the court's docket (pacelle ). the late herbert j. storing made the point well a decade and a half ago. "[i]t seems quite plausible today," stor- ing remarked, "when so much of constitutional law is connected with the bill of rights, to conclude that the antifederalists, the apparent losers in the debate over the con- stitution, were ultimately the win- ners" (storing , ). as a con- sequence of the rights-oriented character of both american politi- cal culture and modern american constitutional law, i have found it easier to introduce students to the sometimes confusing subject of constitutional law, as well as to the daunting task of reading supreme court opinions, through issues with which they are more familiar and more comfortable: rights issues. december the teacher lessons from contracts law as strange as it may sound, my recommendation to reorder consti- tutional law teaching owes much to my former law school contracts teacher, stanley d. henderson. in his contracts course and accompa- nying casebook, henderson takes the bold step of teaching the rules governing remedies for breach of contract (e.g., damages, reliance, and restitution) before the rules governing contract formation (e.g., offer, acceptance, and consider- ation) (dawson, harvey, and henderson ). critics of hend- erson's approach argue that a con- tracts course must begin with the rules governing contract formation. after all, the argument goes, reme- dies questions cannot arise unless a contract is formed. according to henderson, however, it is easier for students to learn the complex world of contracts law through a remedy-centered approach. this is because students are more familiar from their everyday experience with what happens if they breach a contract than they are with the technical rules required for them to form a contract (ibid., xxii). as anyone who has had the good for- tune of taking henderson's con- tracts course or of using his top- selling contracts casebook can attest, henderson's unconventional approach, in which he teaches con- tracts law "backwards," works splendidly. although contracts law and con- stitutional law have little in com- mon substantively, they have much in common pedogogically. like the rules of contract formation, ques- tions of constitutional powers are frequently obscure and confusing to students. by contrast, like the rules governing remedies for breach of contract, constitutional rights ques- tions are quite familiar and under- standable to students, exposed as students are to discussions about abortion and the rights of those ac- cused of crime, for instance, in the everyday discourse of american life. indeed, i venture to say that, before students step into a constitu- tional law classroom, few, if any, have been exposed to questions like whether the legislative veto is constitutional, while many have heard about—and possibly even discussed—"hate speech," to name but two typical examples of the constitutional powers/rights dichot- omy. some suggestions for teaching the rights course my reordered constitutional law sequence does not simply entail teaching the material traditionally offered in a constitutional rights course before the material tradi- tionally offered in a constitutional powers course. although the vast my classroom discussion of the rights-oriented character of american political culture is not limited to the american founding. . . i also turn the class's attention to the contemporary debate over whether we are too rights-oriented in the united states. majority of what i teach in the con- stitutional rights course is tradi- tional constitutional rights materi- al—most notably, landmark cases like lochner v. new york ( ), schenck v. united states ( ), new york times v. sullivan ( ), wisconsin v. yoder ( ), everson v. board of education ( ), mapp v. ohio ( ), gideon v. wainwright ( ), furman v. georgia ( ), griswold v. con- necticut ( ), roe v. wade ( ), bowers v. hardwick ( ), brown v. board of education ( ), frontiero v. richardson ( ), and regents of the univer- sity of california v. bakke ( )— i spend the first several class ses- sions discussing the central place of rights in american political culture in the hopes of setting the appropri- ate mood for the course. i begin by examining the decla- ration of independence, the found- ing document of the american re- gime. indeed, in correspondence with james madison about the uni- versity of virginia's curriculum, thomas jefferson put the declara- tion at the top of his required read- ing list for government and law stu- dents (hellenbrand , ). while it is certainly not my objec- tive to turn the constitutional rights course into a political philosophy course, i try to give my students a general understanding of the politi- cal ideas of the declaration—and as the students quickly come to appreciate, rights are at the heart of those political ideas. i follow the discussion of the declaration of independence with a discussion of the debate over the ratification of the constitution. here, i remind the students that the absence of a bill of rights from the proposed constitution framed in philadelphia in nearly led to the constitution's defeat, a point i illustrate with some revealing quotes from leading antifederalists like mercy otis warren, luther martin, george mason, and patrick henry. i also invoke the name and forceful language of thomas jeffer- son, author of the declaration of independence. jefferson was ini- tially a reluctant supporter of the constitution, i explain, and one of his most famous letters to madison tersely said why. "[a] bill of rights," jefferson wrote, "is what the people are entitled to against government on earth, general or particular, and what no just govern- ment should refuse, or rest on in- ference" (peterson , ). i close my discussion of the rati- fication debate by explaining to the students that, in the end, the an- tifederalists prevailed in the debate over the bill of rights, and the constitution was ratified only be- cause the federalists promised to add a bill of rights at the first op- portunity. that promise soon was fulfilled by madison in the first congress, with madison's change of heart largely being attributable to his recognizing the importance to the american people of securing ps: political science & politics reordering american constitutional law teaching their rights. i quote madison's clos- ing remarks in his june , , speech to the u. s. house of rep- resentatives advocating the adop- tion of the bill of rights to demon- strate the point. " i think we should obtain the confidence of our fellow- citizens," madison argued, "in proportion as we fortify the rights of the people against the encroach- ments of the government" (meyers , ). my classroom discussion of the rights-oriented character of ameri- can political culture is not limited to the american founding, impor- tant as that period in our history is for defining who we are as a nation. i also turn the class's attention to the contemporary debate over whether we are too rights-oriented in the united states. i discuss both the provocative scholarship of con- temporary communitarians like amitai etzioni ( ) and mary ann glendon ( ) and the com- munitarianism of our current presi- dent, bill clinton. most significantly, i alert the class to the majoritarian and com- munitarian inclinations of today's conservative republican court. in stark contrast to the post- roosevelt and warren courts, i suggest, the republican court ap- pears to reject the idea that the constitution commissions the court as the institutional protector of in- dividual rights. i use the "peyote case," employment division v. smith ( ), as an example. there, justice antonin scalia, writ- ing for a sharply divided court, made the startling pronouncement that the values enshrined in the bill of rights—individual religious lib- erty, in particular—are not immune from definition by the political pro- cess. my objective at this point in the course is not to engage the stu- dents in an extended exegesis on religious liberty, but rather to use the case as a vehicle through which they can begin to acclimate them- selves to constitutional law, as well as to reading supreme court opin- ions. that foundation laid, the stu- dents are ready to enter the fasci- nating world of american constitutional law. conclusion in suggesting that constitutional law teaching needs to be reordered, i do not mean to imply that consti- tutional powers questions are less important than constitutional rights questions. my goal is simply to help students learn constitutional law better. in my experience, the order in which constitutional law is taught does not affect students' ability to learn the constitutional rights material. for the reasons dis- cussed above, students have little trouble with the rights material, regardless of whether that material is presented first or second. with respect to constitutional powers, however, students learn that material much better if they have had an opportunity to accli- mate themselves to thinking about constitutional law and to reading supreme court opinions through the more accessible constitutional rights material. hence, my ration- ale for teaching constitutional rights first. after all, our objective as teachers should be to help students learn—even if that means reorder- ing a subject as dear to political scientists as constitutional law. references dawson, john p., william burnett harvey, and stanley d. henderson. . cases and comment on contracts. th ed. min- eola: foundation press. etzioni, amitai. . the spirit of commu- nity: rights, responsibilities, and the communitarian agenda. new york: crown. glendon, mary ann. . rights talk: the impoverishment of political discourse. new york: free press. hellenbrand, harold. . the unfinished revolution: education and politics in the thought of thomas jefferson. newark: university of delaware press. meyers, marvin, ed. . the mind of the founder: sources of the political thought of james madison. revised ed. hanover: university press of new eng- land. mezey, susan gluck. .

). sequence analysis of the mammalian vdac isoforms shows a unique n terminal end in vdac , which is likely to be exposed to the cyto- plasm. to test the functional significance of this n terminus, the first amino acids were removed from vdac or were added to vdac . vdac -/- mef cells that are resistant to tbid, were rescued with these constructs and cyto- chrome c release was monitored in permeabilized cells by single cell imaging and immunoblotting. these studies revealed that cytochrome c release upon tbid application is effectively supported by both full length vdac and the vdac n-terminal deletion mutant. furthermore, vdac extended by the n terminus of vdac failed to restore cytochrome c release in vdac -/- mefs. thus the n terminus of vdac seems to be dispensible for tbid- induced omm permeabilization. currently, we are designing different muta- tions which target some addititional unique sequences in vdac to find the specific domain that is essential for tbid induced cytochrome c release. -plat patch-clamp analysis of mitochondrial ca d uniporter in different tissues francesca fieni, yuriy kirichok. ucsf, san francisco, ca, usa. the mitochondrial ca þ uptake has been recognized as a central player in cel- lular pathophysiology for decades. pathways of ca þ transport across the inner mitochondrial membrane (imm) were investigated indirectly with biochemical techniques and most recently by applying the patch clamp technique to mito- plasts isolated from mammalian systems. patch-clamp recording of the imm have proved to provide an unambiguous picture of mitochondrial ca þ uptake under strictly controlled conditions. in this study, we evaluated and compared the biophysical properties of mito- chondrial ca þ uptake in different mouse tissues. freshly isolated mitoplasts from mouse heart, skeletal muscle, liver, kidney, spleen and brown adipose tis- sue were patch clamped in the whole-mitoplast configuration. voltage step and ramp protocols covering the whole range of physiological potentials were ap- plied to elicit the inwardly rectifying ca þcurrent sensitive to rur known as mcu. the distribution of mcu current densities between tissues was as fol- lows: spleen > brown adipose tissue z skeletal muscle > kidney > liver >> heart. interestingly, mcu current density in heart was about times smaller than in skeletal muscle. our results support the view of a differential tissue activity of mcu, which can be explained by either a different distribution of mcu channel and/or by a different expression of its regulatory subunits confer- ing various modes of physiological regulation. further on, in order to investigate the putative direct contribution of uncou- pling protein isoform and (ucp / ) to the uniporter, we investigated mcu properties in wild type (wt) mouse tissues where these two proteins have been found to have a major role and compared its properties in the corre- spondent tissues of ucp and ucp ko mice. we found no significant differ- ences in calcium currents of any of the wt tissues studied compared to their ucp / ko counterparts. -plat sr-mitochondrial ultrastructure in the heart of normal and ethanol-fed rats gyorgy csordas , david mankus , tanvir shaikh , xing meng , jan hoek , carmen mannella , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, wadsworth center, albany, ny, usa. chronic alcoholism causes various forms of stress in the heart, and this is often accompanied by mitochondrial dysfunction. a putative source of mitochondrial dysfunction is sr-mitochondrial stress and the ensuing mitochondrial ca þ overload. to test this possibility, first we isolated mitochondria from chronic ethanol-fed ( months) and paired control rats, and documented ethanol- dependent sensitization to ca þ and ros-induced permeabilization. to evalu- ate the ultrastructural basis of the mitochondrial impairments, we performed transmission electron microscopy (tem) and electron tomography studies of left ventricular muscle. the overall ultrastructure of the myocytes became less organized in the ethanol-fed condition. also, a considerable fraction of the mitochondria lost the highly ordered structure of the cristae and showed an increase in the cross-sectional area. however, the size of the sr- mitochondrial associations and the gap-width at the interface was unchanged. evaluation of the sr-mitochondrial tethers by electron tomography indicates that they occur in clusters and display heterogeneity in length, as previously re- ported for er-mitochondrial tethers in normal rat liver (csordas et al, , j cell biol, : ). overall tether length distribution appears to be unaltered by alcohol ingestion. analyses of effects of alcohol ingestion on tether membrane-surface density and structural classes (linear, v, y and more com- plex shapes) is in progress, as is d analysis of ser and mitochondrial inner- and outer-membrane topologies.

after world war ii (black, ). until recently, however, i mistakenly believed that retrospective diagnosis was now an historical artifact. i recognized how wrong i was when i happened on a book that proposed that a founding father belongs on the autism spectrum as well as on mount rushmore. autism at monticello in his book diagnosing jefferson: evidence of a condition that guided his beliefs, behavior, and personal associations, ledgin ( ) wrote with certainty that thomas jefferson was a person with autism (more specifically asperger's syndrome). three attributes are presented to support his argument that jefferson had this developmental disability. the first is the founding of the university of virginia. ledgin described jefferson's depth and intensity of involvement in designing the architecture, creating the curriculum, hand-picking the faculty, prescribing student housing, and personally cataloguing the more than , books in the original library of the university. according to ledgin ( ), jefferson actually referred to the university as “a tribute to his genius and, i have no doubt a monument to obsessive behavior linked strongly to traits of asperger's syndrome” (p. ). he described jefferson's library cataloging as a savant- like trait reminiscent of those often attributed to people with autism. the second characteristic of jefferson described by ledgin ( ) as being indicative of autism is his lack of money management skills. he reported that jefferson's inability to keep his income ahead of his debts is typical of individual's with asperger's syndrome and argued that this was “self-deluding … [with jefferson] believing somehow everything relating to money management would end well, [this] together with his keeping irreconcilable financial records—had evidently induced the situation” (p. ). the third attribute that ledgin ( ) discussed was perseveration. the evidence he presented for jefferson's “belaboring a topic endlessly” is his letter writing. ledgin pointed particularly to jefferson's letters to abigail adams after a very intense political dispute with her husband, john adams. his extensive correspondence with abigail began when jefferson's daughter polly died, and it continued for years. after jefferson and john adams reconciled, they resumed direct correspondence. these later letters are described by ledgin as “a treasure and a rich record of the outpourings of contrasting geniuses” (p. ). this is quite a different point of view from the “perseveration” he found in jefferson's earlier letters to abigail. ledgin ( ) also ascribed several of jefferson's personal relationship difficulties to autism. he argued that a lack of warmth toward his mother and jefferson's reported inability to show affection to his own children are clearly indicative of asperger's syndrome. ledgin even made a connection between jefferson's affair with sally hemings and his claim that the third president had asperger's. he wrote that when jefferson returned from france with sally and had established a romantic relationship with her, “he faced the dilemma of balancing at home a private benefit that was taboo against his public image of propriety as a respecter of law and custom” (p. ). explaining the connection, ledgin went on to describe people with asperger's: they live mentally and perhaps emotionally on two planes. they live in our world of nonautistics, but they carry with them a separate and otherworldly ‘reality’—their reality … autistics seem to convert it [their reality] into something palpable. (p. ) disabilities and “the sage of monticello” i am unconvinced by ledgin's ( ) arguments. i think that his thesis that jefferson had asperger's syndrome is fraught with the same weakness and dangers that characterized the family pedigree studies of the eugenics movement. i appreciate the fact, however, that ledgin's book led me to take another look at this remarkable individual and national icon. jefferson's actual experience with disability is documented in several sources. it was not the kind of personal experience portrayed by ledgin ( ); rather, it was a familial experience. thomas jefferson was the sibling of a sister and a brother with disabilities. his relationships with them reveal much about his character as a brother and, perhaps, the attitudes of his time and social class regarding disability. jefferson's younger sister elizabeth has been characterized by a number of scholars as having a serious and persisting disability (brodie, ; mapp, ). she was described by one researcher with the words “rather deficient in intellect” (randolph, , p. ). jefferson cared for his sister after the death of their father. he administered his father's estate and saw to it that elizabeth was attired and treated in a manner befitting a woman of her family's social status (brodie, ). jefferson's account book records that on february , , an intense nighttime earthquake forced all of the family to run outside their home at monticello. apparently, frightened by the darkness and confusion, elizabeth became separated from the rest of the family. she was found dead days later, and on march , he recorded his sister's funeral in his account book (brodie, ). in her biography of jefferson, brodie suggested that his feelings for elizabeth might best be symbolized by a clipping in one of his scrapbooks. it is entitled “elegy on the death of an idiot girl” and it includes the line: “poor guileless thing! … heaven took thee spotless to his own” (p. ). jefferson's only brother, randolph, has been described in jefferson biographies as “retarded” (richards & singer, ). it is clear, however, that he lived a life that was characteristic of southern planters in the th century. he married twice, had seven children and lived on a large plantation (p. smith, ; risjord, ). on the other hand, he had limited verbal skills. his letters, many to his brother, are filled with grammatical errors, poor spelling, and scrawled handwriting. he was clearly no match for the famed intellect of his brother thomas. still, there is no clear and convincing evidence of an intellectual disability. the evidence that does exist has lead two researchers to state that “we might best say that jefferson's brother would today be considered to have learning disabilities rather than mental retardation” (richards & singer, , p. ). although the nature of randolph's disabilities can only be the subject of speculation at this point, it is clear that he experienced difficulties in several areas of his personal and vocational life, that he frequently called on his brother for assistance and that he received the help he needed. thomas advised randolph on the running of his plantation and shared everything from dogs to vegetable seeds with him. he loaned him farming equipment and money, and took his brother's beloved watch to richmond for repair. he also wrote his brother's will for him (malone, ). in a deposition given in , thomas described his brother as “not possessing skill for the judicious management of his affairs” (cited in malone, , p. ). a man who lived as a slave at monticello later dictated his memoirs of those years in . among the recollections of the man who was identified only as isaac was a memory in which the former slave compared the intellect of randolph jefferson to his own in a self-deprecating manner. isaac said: “old master's brother, mass randall, was a mighty simple man: used to come out among black people, play the fiddle and dance half the night; hadn't much more sense than isaac” (cited in bear, , p. ). it may not be surprising that isaac's comment has been used to claim that it was not thomas but randolph jefferson who fathered sally hemings' children and that thomas was not involved sexually with her. in a book published by the thomas jefferson heritage society, coates ( ) wrote that it should be noted that randolph would be more likely to have a sexual encounter with sally than would thomas. randolph was known to socialize with the black slaves at monticello when he visited there. … and since randolph was a widower at the time, it is easy to understand how he could become involved with one of the beautiful house servants. … in addition, randolph was age when eston [a child claimed to be the son of thomas jefferson and sally hemings] was conceived while thomas was . randolph remarried a year after eston was born, and fathered an additional son in that marriage, so he was evidently still sexually active throughout that time period. (p. ) when the issue of randolph's possible paternity of the jefferson–hemings children was raised and questioned, a descendent of thomas jefferson remarked that it had not been discussed publicly before because good taste and respect for the privacy of others was the reason for this rarely mentioned topic. it was bad enough to be illegitimate, much less the illegitimate offspring of a half-witted no account, namely president jefferson's brother, randolph jefferson. (mcmurry, , p. ) the diagnosis: a good brother in a review of the treatment of people with intellectual disabilities in virginia from through , wickham ( ) offered an important perspective on the interaction of social class and “idiocy.” wickham found that a two-tiered system existed. poor and dependant people with intellectual disabilities often met with public scorn and rejection from even a place in virginia's public mental institutions. on the other hand, prominent families responded with “silent avoidance” and hiding of what was perceived to be a family weakness (wickham, ). thomas jefferson was a man of means and elevated public stature. he was also a good brother. in one instance he protected the dignity and well-being of a sister with a severe disability. in the second, he promoted the independence and social inclusion of a brother with a disability who needed his help. these are, indeed, additional reasons why his likeness rightfully belongs on mount rushmore.

specific quality of life questionnaire (msq): a psychometric comparison between the english, finnish, dutch, hungarian, and spanish translations grossman pr, black lk, kwong j glaxo wellcome inc., research triangle park, nc, usa objectives: the msq (migraine specific quality of life questionnaire) measures migraine-related quality of life in three dimensions [role restrictive (rr), role pre- ventive (rp), and emotional function (ef)]. the objec- tive of this analysis was to compare the psychometric properties of the finnish (fn), dutch (hd), hungarian (hg), spanish (sp), and uk english translations with the original us english version of the msq. methods: one hundred and ninety-eight finns, dutch, hungarians, new zealanders, and spaniards, participated in a multinational migraine clinical trial in which the msq was completed at baseline and after a - month treatment period with customary therapy or naratriptan . mg. the distribution of item responses, item-discriminant validity and scale-level reliability for the msq translations were examined and compared to the previously published us english version results. re- sults: the distribution of responses for each item was negatively skewed for all translations. the full range of the response categories was used by migraineurs from all countries except for the fn version in the clinical trial. every translation of the msq possessed item-scale corre- lations that were higher for the hypothesized scale com- pared to competing scales. similar to the us english ver- sion results, baseline cronbach’s alpha coefficients for the three msq dimensions were greater than . for all translations. the msq translations were sensitive to de- tect intervention differences after months of naratrip- tan treatment for migraines. conclusions: the msq translations have demonstrated item-level discriminant validity, reliability, and sensitivity to detect treatment changes in quality of life and has cross-cultural empirical validity. the msq is an effective tool in assessing mi- graine-related quality of life across different cultures. pmh the impact of schizophrenia on health- related quality of life (hrql) for patients admitted to psychiatric units of general acute care hospitals durkin mb , edell ws , mody sh , adams be , repp ea janssen pharmaceutica, titusville, nj, usa; mental health outcomes, lewisville, tx, usa objective: to evaluate the impact of schizophrenia versus other chronic conditions on health-related quality of life (hrql). methods: patients who were admitted to a psychiatric inpatient unit at one of the � acute care hospitals using the cqi�sm outcomes measurement system were administered the sf- health status survey. all patients with a discharge diagnosis of schizophrenia who completed the sf- and were admitted to adult (n � ) or geropsychiatric (n � ) inpatient units were selected. randomly generated observations were drawn from general us population sf- data to con- struct two general population cohorts matching the adult and geriatric schizophrenia samples, respectively, in dis- tribution of age and gender. adult and geriatric schizo- phrenic cohorts were compared to their corresponding matched general population cohort on each of the eight sf- domains. comparisons were also made to three disease cohorts: hypertension, congestive heart failure (chf), and diabetes. independent sample t-tests were used to evaluate differences between the groups. re- sults: schizophrenic patients from both adult and geri- atric groups had significantly lower scores (p � . ) on virtually all mental and physical hrql domains when compared to the general us population and to patients with hypertension or diabetes. both groups of schizo- phrenics scored lower (p � . ) on mental health do- mains when compared to chf patients. adult schizo- phrenics scored higher in the physical health domains than chf patients (p � . ), while geriatric schizophren- ics were similar to chf patients in those domains. con- clusions: schizophrenia’s association with lower hrql extends beyond mental health to physical health status. the physical health status of schizophrenics is more impaired than those observed in patients with dia- betes and hypertension, and is comparable to patients with chf. pmh change in health-related quality of life in patients with schizophrenia taking antipsychotic agents edell ws , durkin mb , mody sh , adams be , white re , qiu az mental health outcomes, lewisville, tx, usa; janssen pharmaceutica, titusville, nj, usa abstracts the perceived health status of individuals with severe psychiatric illness, such as schizophrenia, is an important element of disease burden and quality of life. the effect of antipsychotic therapies on psychiatric symptoms is well-understood. however, more information about the effects of antipsychotics on health status is needed. ob- jective: to examine changes in health-related quality of life (hrql) from inpatient admission to follow-up of adult and geriatric patients with schizophrenia treated with conventional or atypical antipsychotic agents. methods: data were obtained from the cqi�sm out- comes measurement system, an oryx (jcaho) ac- cepted performance improvement system, which tracks patients admitted to adult or geropsychiatric inpatient programs in over general hospitals across states. health status was measured by the sf- at time of ad- mission and at three (geriatric) or six months (adult) post-discharge. patients with a primary discharge diagno- sis of schizophrenia (icd- -cm codes . – . ) who completed the sf- and were treated with antipsy- chotic agents were included. one sample t-tests were used to test the null hypothesis that the mean change is equal to zero. results: mean scores were higher (i.e., healthier) at follow-up, as compared to admission, on all eight domains of the sf- for the adult schizophrenic group (n � ) and seven of eight domains for the geriat- ric schizophrenic group (n � ). statistically significant improvements were noted on five of the eight scales. largest improvements were found on role physical (p � . ), role emotional (p � . ), and social func- tioning (p � . ). conclusions: marked improve- ment in diverse aspects of hrql among schizophrenic patients treated with conventional or atypical antipsy- chotic agents supports the humanistic value of antipsy- chotic medications beyond simple symptom ameliora- tion. pmh the impact of depression on health- related quality of life (hrql) mody sh , edell ws , durkin mb , adams be , repp ea janssen pharmaceutica, titusville, nj, usa; mental health outcomes, lewisville, tx, usa objective: to describe the effect of depression on health-related quality of life (hrql) utilizing the sf- health status survey. the scores of patients with depres- sion were compared to age and gender matched us popu- lation norms and contrasted to results of similar research on patients with other psychiatric disorders. methods: sf- scores were collected from patients admitted to adult (n � ) or geriatric (n � ) psychiatric pro- grams within acute care hospitals who had an icd- -cm discharge diagnosis of depressive disorder. adult and ge- riatric us population norms were simulated using data from the medical outcomes study manual and interpre- tation guide to match the age and gender distributions of the adult and geriatric depression groups. admission sf- scores for the adult and geriatric depression groups were compared to these age and gender matched us popula- tion norms using independent sample t-tests. the find- ings were then placed in context of sf- scores for other psychiatric conditions including schizophrenia, bipolar disorder, and cognitive disorder. results: hrql for both the adult and geriatric groups of depressed patients was significantly lower than the simulated us population norms for all eight domains of the sf- , for physical health as well as mental health (p � . ). the greatest differences were observed in the role physical, social functioning, and role emotional domains. adult inpa- tients with depression had similar scores on all domains to adult patients with the other psychiatric diagnoses studied. however, geriatric patients with depression had lower scores on hrql across all domains versus geriat- ric patients with other psychiatric illnesses. conclu- sions: depression has a strong negative association with both adult and geriatric patients’ perceived hrql. depressed patients not only had the expected decreases on mental health domains, but also scored significantly lower on physical health domains. finally, depression in geriatric patients is associated with greater decrements in hrql than other psychiatric illnesses examined. pmh quality of life differences between patients with episodic and transformed migraine meletiche dm , lofland jh , young wb , hopkins mm office of health policy and clinical outcomes, thomas jefferson university, philadelphia, pa, usa; jefferson headache clinic, thomas jefferson university hospital, philadelphia, pa, usa currently there are no published studies comparing the health-related quality of life (hrqol) of transformed and episodic migraneurs. objectives: the study objec- tive was to detect differences in hrqol between patients

first visit to the center. data collected included the short form (sf- ) and the migraine disability assessment (midas) questionnaires as well as demographic information. a t-test with bonferroni correction was used to test for sig- nificant differences in the sf- domains between the groups. results: to date, data has been collected on patients, from each group. there were no signifi- cant differences with respect to gender, race, age or the number of comorbid conditions between groups. over the last days prior to their first visit, patients with tm reported having a headache on an

in brief precision medicine path for prostate cancer a mainstay of metastatic prostate cancer treatment is the suppression of hormones that fuel tumor cells. how- ever, almost all men with advanced prostate cancer develop resistance to these androgen-depleting therapies. recently, researchers showed that nearly % of patients with metastatic castration-resistant prostate cancer (mcrpc) have a genetic alteration that could be targeted by other clini- cal treatments. the fi ndings suggest individualized approaches for these patients (cell ; : – ). “this will have a major impact on how we move forward in [treating] this disease,” says johann de bono, md, a principal investigator in the study and head of the division of clinical stud- ies at the institute of cancer research in london, uk. “ninety-nine percent of our trials involve no patient prese- lection. with this information, we can now subdivide these patients, as we’ve done with breast and lung cancers.” in this fi rst multicenter, inter- national clinical trial, researchers conducted whole-exome and transcrip- tome sequencing of bone or soft-tissue biopsy samples from patients living with mcrpc. results showed that . % of the patients who had a genetic alteration had androgen recep- tor mutations, a fi nding in line with current understanding of the disease. more compelling, researchers found that of the nearly % of patients with genetic alterations, % had anoma- lies (other than androgen receptor mutations) that could be targeted by investigational or fda-approved drugs currently used for other cancers. among these alterations, almost % occurred in dna repair pathways. for instance, some tumors had brca or brca mutations, which, in ovarian and breast cancers, have shown sensi- tivity to parp inhibitors, drugs that interfere with dna repair and prevent tumor cells from dividing. in addition, researchers mapped more than a half dozen previously unknown genetic changes, such as mutations in the wnt signaling pathway, which leads to regulation of cell development and migration, and a pik cb mutation with cancer-activating effects similar to pik ca. they also found that % of patients with mcrpc had germline mutations. “this is a very important study on a number of fronts,” says karen knudsen, phd, director of the sidney kimmel cancer center at thomas jefferson university in philadelphia, pa, who was not involved in the study. “it’s the fi rst large study looking at the incurable stage of the disease, where the unmet clinical need is. the large cohort gives us confi dence and a much clearer picture of the drivers of disease, and they’ve uncovered new potential drivers that are targetable.” when the study is completed, research- ers will have mapped and sequenced the tumors of patients with mcrpc. amassing such data, says de bono, will lead to more targeted—and more afford- able—sequencing. “it will be critical to follow up with clinical trials that correlate clinical outcomes with molecular alterations,” says arul m. chinnaiyan, md, phd, a senior author on the study and direc- tor of the michigan center for trans- lational pathology at the university of michigan in ann arbor. “the longer- term goal is to have this information ahead of time and be able to direct patients in a more precise way to the best therapy.” ■ cellular backpackers deliver lymphoma drugs researchers have developed a new technique that enlists t cells to ferry chemotherapy drugs into tumors and that improves the effi ciency of drug delivery. cancer cells can elude chemo- therapy by hiding out in lymph nodes and other protected locations. even if a small amount of drug makes it to these refuges, it may not permeate the tissue to reach the tumor cells inside. researchers have tried to overcome these problems by having nanoparti- cles transport chemotherapy drugs, but not all tumors have the leaky blood vessels that enable the particles to leave the bloodstream and disperse into the tumor. people karen e. knudsen, phd, has been named director of the sidney kimmel cancer center at thomas jefferson university in philadelphia, pa, as well as chair of its department of cancer biology. she has been serving in these roles on an interim basis since january. an expert in the molecular basis of hormone-dependent prostate cancer, knudsen aims to prevent and treat the disease. her studies that identify tumor suppressor and hormone-receptor alter- ations have uncovered new targets for treating advanced disease and have led to innovative, biomarker-driven clinical trials. in addition, she is editor-in-chief of molecular cancer research. rolf apweiler, phd, and ewan birney, phd, have been appointed joint directors of the european molecular biology laboratory— european bioinfor- matics institute (embl-ebi), effective july . the european hub for big data in biol- ogy, embl-ebi is based on the wellcome trust genome campus in hinxton, uk. as part of embl, the institute collects, annotates, archives, and shares data from publicly funded life-science experiments with the global scientific community. apweiler and birney will continue to lead their respec- tive research groups. apweiler is involved in many internal col- laborations and initiatives, including the human proteome organization proteomics standards initiative. he has served on the editorial and advisory boards of several journals, and he has published more than papers and book chapters. birney played a vital role in annotating the genome sequences of the human, mouse, and other organisms. he led the analysis group for the encode project. his inter- ests include functional genomics and statisti- cal methods to analyze genomic information. e m b l -e b

protein distribution and function depend on mitochondrial fusion a wednesday, february , voltage-dependent anion channel isoform (vdac ). here, we show that hcc induced by carcinogenic compounds, aflatoxin or den is highly sensi- tized to tbid-induced omm permeabilization and cyto c release when com- pared to normal liver. expression levels of vdac and bak were also higher in hcc than in control liver. the role of the vdac -bak pathway in the differential tbid sensitivity was validated by overexpression of vdac in primary hepatocytes. in hcc cells, elevation of bak was also associated with an increased level of mcl- , an inhibitor of bak. furthermore, both constitutive and drug-induced genetic deletion of mcl- in mouse embryonic fibroblasts caused sensitization to tbid-induced omm permeabilization in the absence of a change in bcl-xl or bax . based on these results, we are evaluating the possibility of selective killing of hcc cells by the combination of a bak activator and an mcl- inhibitor. -pos board b which domain of vdac is necessary for bak insertion to the outer mitochondrial membrane and tbid - induced cytochrome c release? shamim naghdi , peter varnai , soumya sinha roy , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadlephia, pa, usa, semmelweis university, budapest, hungary. vdac proteins represent a main component of the outer mitochondrial membrane (omm). the vdac family is composed of isoforms with more than percent similarity. although their primary role was known to be in ion and metabolite transport between mitochondria and cytosol, it has been dis- covered that vdacs are also involved in apoptotic pathways. we have recently found that specifically the vdac isoform is needed for tbid-induced cyto- chrome c release, due to its role in supporting bak insertion to the omm (roy et al. . embo rep. : - ). to determine the domain(s) of vdac which supports bak insertion, vdac and vdac amino acid composition compared and the unique attributes of vdac sequencewereconsideredformutationalanalysis.totestfunctionalsig- nificance of the changes in vdac or vdac , vdac -/- mef cells that are resistant to tbid, were transfected with the mutants and insertion of bak to the omm and cytochrome c release were monitored in permeabilized cells by immunoblotting. previously, we showed that the vdac -specific n terminal tail and cysteins are dispensable for tbid-induced omm permeabilization. to approach the remaining differences four chimeras were prepared: vdac ( - )vdac ( - ), vdac ( - )vdac ( - )vdac ( - ), vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ). these studies revealed that tbid dependent omm permeabilization is only sup- ported by vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ), indicating that the first two third of vdac is required and sufficient for bak targeting to the omm and tbid induced cytochrome c release. -pos board b outer mitochondrial membrane protein distribution and function depend on mitochondrial fusion david weaver , xingguo liu , veronica eisner , peter varnai , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary. cells and tissues deficient in mitochondrial fusion have been shown to have defects linked to the exchange of inner membrane (imm) and matrix compo- nents, particularly mitochondrial dna. outer membrane (omm) constituents originate in the cytoplasm, thus the role of intermitochondrial transfer of omm components by fusion remained unexplored. here we show that fibro- blasts lacking the gtpases responsible for omm fusion, mfn / , have a more heterogeneous distribution of omm proteins than wild-type cells, and in partic- ular that heterogeneity of pro-apoptotic bak leads to dysregulation of bid- dependent apoptotic signaling. homogeneous distribution of bak is partially rescued by introduction of mfn into mfn / -/- cells. furthermore, fusions be- tween mitochondria lacking and containing bak result in hybrids sensitive to bid. proteins with different modes of omm association display varying degrees of heterogeneity in mfn / /- cells and different kinetics of transfer during fusion in fusion-competent cells. efficient coupling of omm to imm fusion depends on the presence of both mfn isoforms and is antagonized by the mitochondrial fission protein, drp . thus, omm function depends on mitochondrial fusion and is a locus of dysfunction in conditions of fusion deficiency. -pos board b mitochondrial fusion dynamics in skeletal muscle of healthy and diseased rat veronica eisner , guy lenaers , gyorgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, inserm u- , institut des neurosciences de montpellier, montpellier, france. mitochondria are highly mobile and dynamic organelles in many cell types. however, in the muscle, mitochondria are crammed into the narrow space among the myofilaments. until now, it remained unclear if mitochondrial fusion occurs in and supports the contractile activity of skeletal muscle (sm). here we applied mitochondria matrix-targeted dsred and photoactiv- able gfp to study mitochondrial fusion in rat fdb sm fibers. in vivo electro- porated fibers were imaged by confocal microscopy. when we tagged the mitochondria in ~ % of cell area with twophoton photoactivation of gfp, rapid spreading of fluorescence showed subsets of interconnected mitochondria, mostly in longitudinal direction. matrix fusion occurred with a rate of . and . events/min in adult fibers and skeletal myotubes, respectively. expres- sion of autosomal dominant optical atrophy-causing mutants of the fusion protein opa or ethanol exposure caused suppression of fusion, which is fol- lowed by mitochondrial dysfunction and late onset myopathies. when chal- lenged by repetitive tetanic stimulation, ethanol exposed cells displayed intracellular ca þ dysregulation, appearing as a fatigue pattern. ethanol also induced a decrease in mfn protein levels, without significantly altering mfn , opa or deltapsi. depletion of mfn alone was sufficient to suppress mi- tochondrial fusion in fdb fibers. fusion inhibition was apparent before any cell dysfunction, suggesting that suppression of fusion is not secondary to other problems in the cells. to directly test the role of mfn in ca þ regulation, ryr -transfected control and mfn ko mefs were stimulated with caffeine. mfn ko cells showed oscillatory ca þ transients that decayed faster than that in the control. thus, fusion dynamically connects skeletal muscle mito- chondria and serves as a target mechanism of both mutations and environmen- tal cues to cause impaired excitation-contraction coupling. -pos board b bcl- proapoptotic proteins distribution in u- mg glioma cells before and after hypericin photodynamic action katarina stroffekova, lucia balogová, mária maslaňáková, lenka dzurová, pavol mi�skovský mi�skovský. safarik university, kosice, slovakia. apoptosis is a key process in the development and maintenance of tissue homeostasis. this process of controlled cell death is tightly regulated by a balance between cell survival and damage signals. we focused our attention towards the intrinsic mitochondrial apoptotic pathway, where bcl- family of proteins plays the major role. we were particularly interested in two pro- apoptotic players bak and bax. here we investigated their role in apoptosis triggered by photodynamic action. we show the localization of bax and bak in u- mg human glioma cells incubated with photosensitizer hypericin (hyp) before and after photodynamic action. apoptotic stimulus by hyp photodynamic action caused bax translocation into mitochondria. however our results suggest that under these condi- tions there are two populations of mito- chondria: one which contains bax and bak simultaneously, and is almost exclu- sively localized near the plasma mem- brane; the other which contains bax only and is distributed throughout the cell. the different protein content and spatial distri- bution of these two populations suggest that they can play different roles in re- sponse to apoptotic stimuli. -pos board b stimulation of bax mitochondrial localization by bcl-xl thibaud renault , oscar teijido , gisele velours , yogesh tengarai ganesan , florent

interactions between the bcl- family proteins. an imbalance of this interaction network due to the up-regulation of the proto-oncogenes bcl- and/or bcl-xl lead to a resistance to apoptosis and is associated with tumor formation. bcl-xl overexpression act at the level of the mitochondrial outer membrane (mom) by inhibiting bax-mediated apoptosis; more particularly mac formation and cytochrome c release. how- ever, the molecular mechanisms through which bcl-xl affect earlier steps of bax-mediated apoptosis are not fully understood. surprisingly, we found that mitochondrial bax redistribution and change of conformation were not inhibited but rather spontaneously increased in response of bcl-xl overexpres- sion. in order to further investigate the molecular mechanisms involved in this which

abstract—objective: to compare the efficacy of step training with body weight support on a treadmill (bwstt) with over-ground practice to the efficacy of a defined over-ground mobility therapy (cont) in patients with incomplete spinal cord injury (sci) admitted for inpatient rehabilitation. methods: a total of subjects from six regional centers within weeks of sci were entered in a single-blinded, multicenter, randomized clinical trial (mrct). subjects were graded on the american spinal injury association impairment scale (asia) as b, c, or d with levels from c to l and had a functional independence measure for locomotion (fim-l) score � . they received weeks of equal time of bwstt or cont. primary outcomes were fim-l for asia b and c subjects and walking speed for asia c and d subjects months after sci. results: no significant differences were found at entry between treatment groups or at months for fim-l (n � ) or walking speed and distance (n � ). in the upper motor neuron (umn) subjects, % of asia b, % of asia c, and all asia d subjects walked independently. velocities for umn asia c and d subjects were not significantly different for bwstt ( . � . m/s, n � ) and cont ( . � . , n � ) groups. conclusions: the physical therapy strategies of body weight support on a treadmill and defined overground mobility therapy did not produce different outcomes. this finding was partly due to the unexpectedly high percentage of american spinal injury association c subjects who achieved functional walking speeds, irrespective of treatment. the results provide new insight into disability after incomplete spinal cord injury and affirm the importance of the multicenter, randomized clinical trial to test rehabilitation strategies. neurology ; : – annually, approximately , americans have a traumatic spinal cord injury (sci). for many pa- tients, the most visible lingering disability is the in- ability to walk or a slow spastic-paretic gait with high energy cost. a gait training strategy, using body weight support on a treadmill (bwstt), , has evolved from physiologic studies of the effects of the level and timing of limb loading during stepping and of stance and swing phase kinematics in spinal transected quadrupeds - and in patients with com- plete sci. - the experimental intervention received clinical support from nonrandomized studies of pa- tients with incomplete sci early and late after injury. , , - no randomized trials with blinded out- comes, however, had compared different physical therapy strategies aimed at the recovery of walking during initial inpatient and outpatient rehabilita- tion. further, no prospective trials in sci had col- lected measures related to functional walking, such as walking speed, distance, and the need for assis- tive devices. , the spinal cord injury locomotor trial (scilt) was a single-blinded, parallel-group, multicenter, randomized clinical trial (mrct) that compared two interventions for walking: bwstt vs a similar in- tensity of a defined control (cont) program of over- ground mobility training. subjects had an incomplete sci on admission to each site graded on the american spinal injury association impairment scale (asia) as b, c, or d. the functional indepen- dence measure locomotor (fim-l) walking scores, obtained at inpatient admission and discharge from the participating

recruited potential subjects by screening all admissions to six cus, each a regional sci center, from june to january . coordination and central data management were carried out at the university of california los angeles. institutional review board approval was obtained from each site. written informed consent was obtained from each subject prior to inclusion. the design and methods for this trial, including efforts for training and standardizing thera- pies and data collection, have been reported in detail. a sum- mary of important features follows. subject selection and randomization. patients were entered within weeks of onset of incomplete sci and within week of admission for rehabilitation. subjects with a cervical to t /t lesion were designated as the upper motor neuron (umn) group. subjects with a t to l lesion were designated as the lower motor neuron (lmn) group if they had no umn neurologic signs. if subjects with a low thoracic lesion had umn signs on one side and lmn signs on the other, they were designated umn. inclu- sion and exclusion criteria are listed in table . subjects were excluded at time of randomization if they needed antispasticity medication other than overnight. after entry, use of medication was determined by the treating physician. subjects were assigned to their treatment group using a random, permuted block design with the factors umn-lmn and asia b-c-d across all cu sites and generated by the ucla statistical coordinating unit. treatment. all subjects received the cu’s standard inpatient and outpatient rehabilitation therapies for mobility and self-care skills. within this routine, the main component of their mobility training was weeks of either bwstt or cont therapy for walking. they did not receive any formal training for walking other than during these sessions. the bwstt group had its mo- bility training for up to hour each day of therapy. the specific amount of time spent standing or stepping depended on each subject’s level of exercise-induced fatigue. the physical therapists proceeded with stretching exercises for up to minutes, then step training on the treadmill using bws for to minutes in - to -minute increments. walking over ground was practiced, once feasible, for an additional to minutes each session. for bwstt, subjects wore a climbing harness (robertson harness, henderson, nv) attached to an overhead lift that used a gas cylinder to enable vertical displacement during the step cycle (vigor co., stevensville, mi). weight support and treadmill speed were adjusted to enable training at speeds greater than . m/s with a goal of over . m/s. stepping with partial weight sup- port as needed was expected to allow therapists to initiate therapy for walking before patients were able to fully bear weight, prior to developing adequate motor control for balance and stepping, as well as allow practice of reciprocal stepping at faster speeds with greater safety and less fear of falling than early over-ground reha- bilitation training would ordinarily permit. the trainers in the bwstt group concentrated, both on and off the treadmill, on assisting trunk and lower extremity kinematics, limb loading, and the cutaneous and proprioceptive feedback that would approach those used by healthy subjects during reciprocal stepping. the scilt trainer’s group intermittently monitored the technique of bwstt at each cu by videotape and provided help in solving training problems. the cont group also had its mobility training for up to hour each day of therapy. the specific amount of time spent standing or stepping depended on each subject’s level of exercise-induced fatigue. the physical therapists proceeded with stretching exercises for up to minutes, followed by a minimum of minutes of standing for those subjects who could not take steps. subjects who could take steps practiced in parallel bars or over ground with assistive devices, braces, and physical assistance from one or two therapists within their exercise tolerance for to minutes. the cont subjects were not allowed to use a treadmill or bws. the goals of bwstt were not discussed with the therapists assigned to treat the cont group. the two approaches were carried out at different locations within each cu. for both mobility interventions, practice aimed to progressively increase task difficulty, be repetitive, maintain the attention of subjects, and reinforce successful skill acquisition. subjects were permit- ted to stand and walk, if feasible, during other portions of their inpatient and outpatient care, such as during routine occupa- tional therapy and at home for daily activities. both groups were permitted to perform leg and trunk strengthening exercises. the maximum number of bwstt or cont sessions would have been if subjects had received five sessions weekly for weeks, or the equivalent of about hours of formal mobility training. the number of training sessions was expected to vary among subjects from a minimum of to the maximum of sessions of their respective intervention. treatment sessions could be stopped when individuals reached the highly func- table

therapy if recommended by the treating physician. adverse training events were moni- tored and reviewed by the external safety and data monitoring committee. outcome measures. the primary outcome measures in- cluded the fim-l and over-ground walking speed. these tests were performed by trained, blinded observers at a site where they would not encounter subjects during treatment times. the internationally accepted standard for the fim-l uses a -foot walk for levels to but requires a -foot walk for levels and . a fim-l score of means the patient requires total physical assistance; , maximum assistance of person; , mod- erate assistance; , minimal assistance (hands on contact); , supervision (not safe alone, but no physical help); , indepen- dent with equipment; and , no need for assistive devices. walking speed was calculated for the faster of two -foot ( . - meter) walks in patients who were able to walk that distance with moderate or less assistance. patients were asked to walk as fast as safely possible. these outcomes were obtained at entry (baseline), every weeks for weeks, at the end of the training intervention ( months), and at and months after entry into the study. secondary outcomes were collected at baseline and at , , and months. they included the distance walked in minutes to assess endurance and fitness, the berg balance scale to assess trunk and leg motor control (range to ), the walking index for spinal cord injury (wisci) (range to ) to assess functional limitations that require braces and assistive devices, the lower extremity motor score (lems) (range to ) to assess strength, the ashworth scale for hypertonicity, and the sf- for self- perceived quality of life. changes and interrelationships among these measures will be reported in other publications. of the , forms with subject data expected from the coordinators and blinded observers at the cus, % were complete when received by the statistical coordinating unit. sample size.

statistical analysis. a four-way design was employed with three stratification factors (umn, lmn, cu site), one treatment factor, a repeated-measure time factor (onset of sci to randomiza- tion), and the primary endpoint (fim-l or walking speed) for asia b, c, and d entries. the analyses at baseline were con- ducted on those patients who had performance data such as walk- ing speed available. for the intention-to-treat paradigm, the cus asked subjects at the time they voluntarily withdrew from the trial to return for - and -month visits, but the institutional review boards would not permit an investigator to contact a sub- ject who had withdrawn. the method of imputation was the last observation carried forward and included subjects who completed at least weeks of mobility intervention. permutation tests and modified fisher tests were used for the analyses of baseline data between the bwstt and cont groups. the -month analyses used a robust regression approach with a two-way design. where the distributions were bimodal, a logistic regression analysis was performed using the standard asymptotic (wald) or quasi-exact method. ordinal or quantitative scales were split at a predetermined value (fim-l score � or � , for exam- ple) and after examining histograms of the data distribution to derive a binary endpoint to carry out standard binary scale anal- yses. when data included outliers and influential points, we ap- plied the huber regression analysis to lessen the effects, for example, of the few very fast and very slow velocities in �outlier� subjects. results.

(bwstt, n � ; cont, n � ) stopped before weeks of mobility training was com- pleted. reasons for refusal to continue at any time after entry included disappointment at assignment, rapid re- covery no longer requiring therapy, and rehabilitation therapy “too difficult.” no differences in rate or cause for withdrawal were observed between the bwstt and cont groups. the -month analyses for walking speed included subjects with an umn lesion initially graded asia c or d who completed their training and all outcome measures. the study fell short in recruiting asia d umn and lmn subjects. several cus reported that asia d subjects no longer were being referred to their regional centers by , instead going to commu- nity facilities. randomization. the baseline characteristics and out- come

asia c and d subjects who were able to complete the -foot walk (n � , table ). the baseline characteristics of the bw- stt and cont groups revealed no differences in age, gen- der, race, days since

two of patients able to walk feet at entry, both who were in the cont group. futility analysis and change in primary analysis. the fim-l was originally planned for use in the primary outcome analysis of asia b and c subjects, whereas walking speed was planned for only asia d subjects, who were expected to become independent walkers re- gardless of assigned intervention. we did not enter a sufficient number of asia d subjects for this primary analysis. a comparison of bwstt and cont for walk- ing speed in asia c and d subjects who were able to perform the task was originally planned as a secondary analysis, however. the majority of asia c subjects in the bwstt and cont groups reached functional walk- table baseline measurements for umn and lmn subjects in intention-to-treat analyses

gathered from the cus. thus, a change in the primary analyses was required. we combined the asia c and d subjects who could walk for the primary analysis of walking speed. prior to stopping the trial, a conditional power analy- sis was undertaken at the direction of the safety and data monitoring committee. futility analyses based on available data revealed that to detect a conditional power of % for the primary outcome measure of fim-l, an additional , subjects would have been needed. for a conditional power of % to detect a % difference in walking speed, an additional , asia c and d subjects would have been needed. thus, we report the primary outcomes for those subjects enrolled by the time of the interim analyses for fim-l in the asia b and c subjects and for walking speed for asia c and d subjects who were able to walk. we did not recruit a sufficient number of lmn subjects to complete indepen- dent analyses for those with conus/cauda equina sci. we separately report the combined umn and lmn sub- jects within each experimental group in the primary planned analysis as well as each umn group as planned for a secondary analysis because mechanistic differences of the response to bwstt may exist between individu- als with umn and lmn lesions. primary outcome analysis: asia b and c for fim- l. the primary outcome measures were obtained at months after entry, which was months after bwstt or cont was completed. statistical analyses were per- formed for intention to treat on data from asia b and c subjects who completed at least weeks of intervention for umn and lmn groups combined (n � ) and for umn subjects only (n � ) (table ). no statistical difference was found between the two groups for fim-l score. thirty-three percent ( / ) of asia b subjects in the bwstt group were ambulatory at months and % ( / ) in the cont group. of the asia b subjects who reached an fim-l score � , of who achieved this score would have been randomized as asia c if entered at the maximum eligibility time of weeks after sci. the majority of asia c subjects recovered indepen- dent walking; % of bwstt and cont subjects ( / in each group) had a fim-l score � at months. asia c subjects were significantly more likely than asia b subjects to walk independently and both asia b and c subjects who were randomized earlier (� weeks after sci) had a greater probability of recovery to a fim-l score � (table ). primary outcome analyses: asia c and d for walking speed. intent-to-treat analyses were performed on data from umn and lmn subjects graded asia c and d who could walk over ground and completed at least weeks of intervention as well as on of the umn subjects (table ). no statistical differences between treatment groups were observed in walking velocity at months for the combined umn/lmn subjects or the umn subjects alone. the median measures for velocity in the asia c and d subjects demonstrated a remarkably high level of walk- ing ability and fell within the range of functional commu- nity ambulation. secondary outcome analyses: umn asia c and d at months. the median quartile walking velocities at months for umn asia c and d subjects were unexpect- edly high in both arms ( . m/s [table ]). these analyses were performed on the of bwstt and of cont subjects at months who could complete the walk- ing test. regardless of the method of statistical analysis carried out on the asia c and d groups, including the effect by cu and time since onset of sci, no significant differences were found between the two interventions for fim-l, walking speed, endurance, lems, berg balance scale score, or wisci score. figure shows the change in walking speed at months compared to months for asia b, c, and d subjects who were walking and illustrates the overlap in walking speeds for the two arms of the trial. this figure also illustrates the change from entry, when walking speed was zero for these subjects, to the velocities at- tained at or months. walking speed at the end of treatment was highly correlated (r � . ) with the speed at months, but speeds continued to increase between and months. earlier time of entry (� weeks) into the mrct after onset of sci was associated with faster walking speeds (p � . ) and longer walk- ing distances (p � . ) in both arms at months for each asia group compared to velocities attained in sub- jects in that group who were randomized � weeks after sci. this finding was primarily related to subjects who were entered at a lower asia level at � weeks after sci (e.g., asia b or c) and attained the next higher asia level (e.g., asia c or d) within the next to weeks. the number of treatment sessions was higher (p � . ) in the bwstt group ( . � . ) than the cont ( � ) for the intention-to-treat analysis of all umn and lmn subjects. this difference was found, however, only for the asia c subjects. the difference in the number of sessions was attributable in part to a higher number of individuals in the cont group who reached the maximum walking speed of . m/s prior to completion of the minimum sessions. either the subjects or their therapists deter- mined that they had no need to continue cont rehabilita- tion for gait training. an analysis of only the umn subjects, however, revealed no significant difference in number of treatment sessions for the combination of b, c, and d subjects or for the asia c subjects in each arm of the trial. adverse responses. no differences in adverse reactions were found between the two arms during treatment. most complications during rehabilitation were not related to the interventions. no excess muscle strain, joint pain, or other potential complications of mobility training were docu- mented from a list on one of the report forms. based on questions and about pain from the sf- , no differ- ences were found. based on the ashworth score, no differ- ences in tone of the lower extremities or frequency of spasms at or months were found for umn subjects randomized to each intervention. discussion. no significant differences were ob- served at months for the fim-l for asia b and c subjects or in walking velocity for asia c and d subjects between the bwstt and cont groups. these individuals represented incomplete sci pa- tients referred to the regional rehabilitation centers neurology february ( of ) at scott memorial library @ thomas jefferson university on january , www.neurology.orgdownloaded from http://www.neurology.org who fulfilled the inclusion/exclusion criteria and could not ambulate without human assistance. subjects were similar in demographics and out- come measures at baseline, suggesting successful randomization. the “median” umn subject who was initially graded asia c or d on admission to a scilt cu became able to walk independently by months after sci at velocities that usually allow unlimited community activity. for umn c and d subjects, the outcomes were internally consistent at the primary endpoint of months in terms of walking speed, distance, and level of indepen- dence, which occurred in parallel to gains in leg strength (lems) and berg balance scale score (ta- ble ). thus, both internal and external validity of the results is likely. for umn asia b subjects, neither treatment led to gains in over-ground walking. most of the subjects who did improve to have a measurable walking speed were entered as asia b soon after sci and converted to asia c within the -week entry period (but continued to be considered as asia b for data analysis). thus, patients who are still graded asia b at weeks after sci have a low probability of achieving functional walking with a fim-l score � when treated with either bwstt or cont. the asia c and d subjects in both treatment groups achieved walking abilities beyond what had been expected (figure ) based on the available literature at the start of scilt and the experience of the investigators. , based on data collected in from the scilt sites, no more than % of asia c patients were expected to walk at dis- charge from the inpatient service with a fim-l score � . at the interim analysis, % of asia c and d subjects in the cont group were able to walk and % performed at walking velocities greater than . m/s. the asia c and d subjects in the bwstt group also reached these levels of walking ability. the trial was stopped before the planned number of asia d subjects was recruited based on the outcome of the futility analyses; re- sults were reported on those subjects entered by the time of completion of the interim analyses. we did not enter enough subjects with conus/cauda equina sci, which represents about % of trau- matic sci, to be able to make an independent analysis of lmn subjects. for patients graded as asia c on admission for rehabilitation, the scilt revealed less disability related to walking by months after sci than had been assumed from studies performed at single sites. in scilt, most individuals graded asia c ( / bwstt; / cont) at entry became able to walk independently. attained velocities for umn asia c and d individuals also did not differ between bwstt and cont groups (median . and . m/s; table ). walking speeds were so much faster than expected that the hypothesized % increase using bwstt that was used for the statistical power analysis would not have been clinically meaningful even if present. no prior studies had reported the walking speeds achieved during rehabilitation. indeed, few data were avail- able in the literature about walking-related out- comes after sci. the sites that

take steps for at least short distances. of the umn asia c and d subjects in scilt who were unable to walk at entry, % (bwstt / and cont / ) walked at least feet without assistance. thus, the wernig et al. study cannot be interpreted as showing that bwstt is more efficacious than training without bws on a treadmill. rehabilitation trials may fail to reveal a differ- ence between an experimental and control therapy because they do not provide the necessary dose of the experimental treatment or do not maintain sufficient differences between the experimental and control interventions. we standardized the cont mobility therapy to include similar intensi- ties of weight bearing for standing or, when feasi- ble, time spent training to walk. the number of mobility training sessions for the cont and bw- stt group aimed to be equal. this was achieved for the asia b and d subjects and the umn asia c subjects. although a trend was present for the bwstt groups to have received more therapy ses- sions than the cont, the two arms had equal outcomes. the ability of the cont and bwstt subjects to take steps over ground determined how much they would practice walking on level surfaces in each session. if patients developed the ability to take steps, usual rehabilitation care proceeded to try to improve over-ground walking skills. possibly, the intensity of therapy for walking in both treatment groups may have been greater than what some rehabilitation providers offer to their physically assisted walkers who are graded asia c. the scilt cannot directly address this possibility since other intensities of mobility-related activity were not studied. one of the rationales for bwstt was to allow earlier step training and a higher intensity of initial practice. the contrast in the amount of standing and stepping between the two groups, however, was probably less than antici- pated. subjects in the cont and bwstt groups were required to weight bear or practice walking, when feasible, for similar amounts of time. the mrct’s primary aim was to compare the potential advantages of bwstt to cont within similar practice durations, not to compare different amounts of therapy time. the early gains by asia c and d subjects in both arms by weeks after entry (data not shown) and by the end of weeks of training compared to the more modest addi- tional gains in walking speed by months (figure ), suggest that bwstt may, in effect, have be- come only a marginally different training strategy than cont during the intervention, at least in terms of intensity of early practice of walking. the trial, however, was designed to test two treatment strategies and found that they were equivalent for the outcomes measured. the better than expected walking velocity outcomes in asia c subjects in scilt may also be attributed in part to the em- phasis on task-oriented therapy for all subjects, the entry of subjects without serious comorbidities, and a preponderance of patients with cervical cen- tral cord injuries who have a fair prognosis for recovery of walking. given that bwstt and cont provided equivalent outcomes for subjects in scilt, clinicians and patients can base their use of each strategy on personal preferences, skill, availability of equipment, and costs. bwstt for asia b subjects with umn lesions did not improve outcomes over cont therapy. bwstt was expected to induce mechanisms of activity-dependent plasticity within the spinal cord, which would be reflected in locomotor gains. if mechanisms of spinal plasticity in humans are to be used for functional walking, greater su- praspinal input or other interventions that modu- late posture and spinal stepping oscillators will be necessary. the highly functional outcomes in most of the asia c and d subjects regardless of the intervention suggest that when some threshold of supraspinal input and segmental sensory feedback are available, task-specific training can lead to im- proved walking. interventions that meet criteria for success, such as training hind limb stepping in spinal transected cats and rats or employing a physical therapy strategy for walking in single-subject de- signs, are critical for the development of new reha- bilitation therapies to improve motor control. the results of these types of experiments may support further scientific study of a new intervention, but the experiments cannot stand alone as evidence of the efficacy of the approach. the results of scilt reemphasize the value of mrcts with blinded out- comes in rehabilitation research, especially to evaluate new and complex physical therapies. sta- tistically sound mrcts in neurorehabilitation with adequate numbers of subjects, distinctively defined interventions, blinded outcomes, and rele- vant outcome measures had only been attempted several times prior to scilt. , this study dem- onstrated that complicated physical therapy ap- proaches can be taught to therapists and implemented across sites. the scilt confirmed the feasibility of carrying out an ethical, scientifi- cally rigorous trial within the time and physical constraints of customary inpatient and outpatient services. the results also provided quantitative data about functional outcomes after sci that dif- fer from reports of volunteer subjects from a single site, which will improve power analysis calcula- tions for future trials that assess recovery of walking. future trials of bwstt may aim to improve outcomes in asia b subjects who have no motor control beyond weeks after sci and in asia c subjects who still cannot walk more than to months after sci. pilot studies of chronic asia c february ( of ) neurology at scott memorial library @ thomas jefferson university on january , www.neurology.orgdownloaded from http://www.neurology.org patients who cannot walk suggest that the combi- nation of bwstt with functional electrical stimu- lation or robotic assistive devices may improve stepping. , bwstt may be a valuable training adjunct in future trials of biologic interventions that promote axonal regeneration toward the lum- bar cord to physiologically incorporate this input because the technique may be less physically bur- densome on therapists and safer for assisting asia a and b subjects to stand and step than conventional physical therapy. testing these ap- proaches will require well-designed mrcts. acknowledgment the authors thank the staff of each rehabilitation center and the individuals who participated in this study. they also

h e a l t h ( ) a – a a according to psoriasis area and severity index (pasi) and dermatology life quality index (dlqi) scores. methods: all patients who stayed on the same active treat- ment for weeks were included. active treatments were subcutaneous secuki- numab mg (n= ) or mg (n= ) at weeks , , , , and , followed by dosing every weeks, and subcutaneous etanercept mg twice weekly for weeks and then once weekly (n= ). total aucs over the -week period by percentage of pasi- / / and dlqi- / (no impact on patient quality of life) responders—measuring overall controlled disease time—were determined using all responder numbers at all scheduled visits. results: total aucs for patients who received secukinumab and mg, and etanercept, respectively, were: . , . , and .

(sd . ), and % were taking at least one depression and/or psychotropic medication. for those reporting these medications, ( %) reported medication, ( %) reported medications, and one ( . %) reported medications. participants with higher phq- scores were more likely to report ≥ depression and/or psychotropic medication (p = . ). no significant associations were found between use of these medications and demographic or medical variables with the exception of cardiovascular dis- ease (p = . ). conclusions: individuals with amd are at risk for depressive disorders due to the substantial impact vision loss has on quality of life. in this study, about one third of patients reported depression and/or psychotropic medi- cation treatment. while this rate is higher than prior studies, findings suggest an opportunity to increase the number treated with medications and/or behavioral approaches. pss study of psychological stress and acne vulgaris among pharmacy students ab hadi h., awadh a. international islamic university malaysia, kuantan, malaysia objectives: acne vulgaris is described as a common skin disease involving block- age and inflammation of pilosebaceous unit such as hair follicles and sebaceous gland. as many factors may contribute to the formation of acne, this study attempt ( . %). approximately , ( . %) had a coded ae. of the ae patients, . % were persistent with treatment despite the ae, . % switched to another treatment within . days, and . % discontinued therapy within . days. ae patients incurred $ (medical: $ , pharmacy: $ ) in rosacea-related costs, while patients without aes incurred $ (medical: $ , pharmacy: $ ). conclusions: the majority of aes associated with current rosacea drugs/formulations resulted in treatment switch/ discontinuation. new drug/formulation may provide additional treatment options for patients with aes and lead to improved persistence and better symptom control. pss indirect treatment comparison of interventions for neovascular (wet) age-related macular degeneration (wet amd) malcolm w.a. , hodgson r. , glanville j. , barata t. , fleetwood k. novartis uk, frimley, uk, york health economics consortium, york, uk, quantics consulting ltd, edinburgh, uk objectives: to undertake a network meta-analysis (nma) to assess the effective- ness of licensed interventions (aflibercept q , ranibizumab prn, pegaptanib and photodynamic therapy (pdt)) in the treatment of neovascular (wet) age-related macular degeneration (wet amd). methods: a systematic review was undertaken to identify trials comparing any of the interventions to treat neovascular amd reporting change in best corrected visual acuity (bcva). a nma of the studies was carried out using winbugs. identified studies often reported results at multiple time points. hence, a number of models were applied accounting for the time structure in the data. the deviance information criterion (dic) was used to select the most appropriate model. multiple separate networks were applied to the data to account for the fact that posologies were equivalent at some time points. results: tri- als were included in the network. aflibercept and ranibizumab were found to be statistically superior to pdt and pegaptanib at and months. the mean change from baseline bvca estimated between ranibizumab and pdt at months was . [ . to . ] and at months was . [ . to . ]. the mean change from baseline bvca estimated between ranibizumab and pegaptanib at months was . [ . , . ] and at months was . [ . , . ]. results for afliber- cept were quantitatively similar. there was minimal difference in the effectiveness of ranibizumab and aflibercept at any time point: mean difference at months numerically favoured ranibizumab by . [- . to . ] and at months by . [- . to . ]. conclusions: aflibercept and ranibizumab are effective treatments for neovascular amd demonstrating a clinically and statistically significant differ- ence in bvca compared with pdt and pegaptanib. there were only minimal (non- statistically significant) differences in the relative effectiveness of aflibercept and ranibizumab at any time point. pss comparative effectiveness of

preservative-free (pf) fixed combination (pf btfc) solution in single-dose vials for the treatment of glaucoma/ocular hyper- tension (oht) compared to alternative therapies has been updated (harvey et al ). the outcome of interest was change from baseline (cfb) in intraocular pressure (iop). methods: systematic searches originally conducted in october were updated to identify additional randomized controlled trials investigat- ing the efficacy of glaucoma/oht therapies, where efficacy is defined as iop cfb. a bayesian model with random effects for trial, week and time of day was fitted to synthesize the resulting evidence base. results: in total, studies met the pre-determined mixed treatment comparison inclusion criteria, represent- ing unique treatment arms. pf btfc was numerically superior to all treat- ments (monotherapies and combination therapies; preserved and pf therapies) in lowering iop and statistically significant (p< . ) for all but seven of the comparisons. furthermore, despite some trials being adequately sized and the treatment effect showing similar levels of uncertainty to others in the network, the credible intervals (ci) for these treatments were among the widest in the network. conclusions: pf btfc was numerically but not statistically superior to all treatments in lowering iop. the sample size required to show statistically significant results in nmas is larger than for head-to-head randomized trials because the precision of comparisons made across a network is proportional not only to the size and uncertainty of individual trials but also to the number of nodes separating treatments (thorlund ). this is thought to be a key driver of the width of cis for some treatments within this network. results from the updated nma will be presented along with a discussion of the interpretation of results for large and complex networks. pss efficacy of secukinumab in patients with plaque psoriasis: area under the curve of treatment

stem cell transplantation in primary refractory acute mye- loid leukemia craddock, c.f. , labopin, m. , schmid, c. , mohty, m. , rocha, v. queen elizabeth hospital, birmingham, united kingdom; faculte de medecine st-antoine, paris, france; klinikum augsburg, germany; nantes hospital, nantes, france; hopital st louis, paris, france treatment options for adults with primary refractory aml (pref aml) are extremely limited. whilst sibling allogeneic stem cell transplantation can result in long term survival most pa- tients lack a matched family donor and are destined to die of refrac- tory disease. greater availability of unrelated donors and improvements in supportive care have increased the proportion of patients with pref aml in whom allografting is technically fea- sible but the outcome of unrelated donor transplantation in this population has not been extensively studied. we therefore analysed overall survival in patients with pref aml who underwent unrelated donor transplantation between and with a me- dian follow-up of months ( - ). patients received three or more courses of induction chemotherapy. the median percentage of bone marrow (bm) blasts at transplant was %. the -year overall survival for the whole group was %. in multivariate anal- ysis, fewer than three courses of induction chemotherapy, a lower percentage of bm blasts at transplant and patient cmv seropositiv- ity were associated with improved survival. we used the prognostic factors identified in multivariate analysis to develop a scoring sys- tem. this allowed the delineation of four prognostic groups with survival rates ranging between % and %. this study dem- onstrates an important role for unrelated donor transplantation in the management of selected patients with pref aml and confirms the importance of initiating an urgent unrelated donor search in pa- tients with no matched sibling donor who fail to respond to induc- tion chemotherapy. pre-transplant factors allow the identification of patients with pref aml who are likely to benefit from unre- lated donor transplantation. hla disparity and rapid immune reconstitution do not over- come propensity to relapse in

philadelphia, pa; thomas jefferson university hospital, philadelphia, pa; thomas jefferson university hospital, philadelphia, pa while increasing hla disparity is known to be associated with increased risk of significant graft versus host disease (gvhd), there is less data as to whether increasing hla disparity is corre- lated with stronger, clinically significant graft versus leukemia ef- fects. we examined a group of patients with acute leukemia undergoing haploidentical hsct to assess whether ) there was a marked difference in relapse rates based on the degree of hla mismatch and ) if early recovery of donor lymphoid subpopula- tions was associated with less relapse after hla mismatched hsct. thirty-four adult patients with aml ( ) and all ( ) underwent haploidentical hsct between and using a step process which separates the infusion of the lymphoid and myeloid portions of the graft while attempting to render the lymphocytes tolerant utilizing cyclophosphamide. the patients re- ceived x e /kg donor cd cells (dli) after conditioning with either tbi gy (n ) or fludarabine mg/m � , thiotepa mg/m � , and tbi gy (n ). two days after the dli, all patients received cyclophosphamide (cy) mg/kg � followed by a cd selected donor product. the tbi based regimen was given to % of patients with all and % with aml. we exam- ined relapse rates based on the number of antigen mismatches at a, b, cw, and drb in the gvh direction. there were no discern- able differences based on degree of hla disparity with even the most haplodisparate group exhibiting high rates of relapse when disease was present at hsct. in contrast, the presence of active leukemia at the time of hsct had far more impact on subsequent relapse rates (see table). table . outcomes based on degree of hla disparity

n/a cr at hsct ( %) / ( %) / ( %) n/a / ( %) total / ( %) / ( %) / ( %) / ( %) we also examined the impact of immune recovery on relapse. ab- solute numbers of nk, and cd and cd t cells were examined in the first months post hsct. t cell, mnc, and total chimerism was greater than % donor-derived at the time of the assessment. for patients who did or did not relapse post hsct the median numbers of lymphoid subsets (cells/ul) were: nk ( - ) vs ( - ), cd ( - ) vs ( - ), and cd ( - ) vs ( - ) respectively. in this small series of patients treated with the step transplant method, relapse was associated more with the presence of disease at hsct than with any discern- able trend in degree of hla disparity or early immunologic recov- ery. other approaches to treat resistant leukemia are required to substantially improve disease free survival in these high risk patients. anti-hla antibodies predict graft failure, time to engraft- ment and umbilical cord unit dominance in double

failure in unrelated donor and single umbilical cord blood (ucb) transplantation. we measured hla-ab in double ucb transplantation (ducbt) with the hypothesis that hla-ab would predict time to engraftment, graft failure and ucb unit dominance. methods: patients with banked pre-transplant sera who under- went ducbt using / or better allelic hla-matched ucb units ( - ) were studied. labscreen (one lambda inc.) was used to capture class i/ii hla-ab and the luminex is system was used to detect fluorescent tagged binding of human igg. visual software was used to normalize results and to deter- mine the presence of mixed class i/ii hla-ab. positive samples were tested using single antigen-coated microbeads. beads with a mean fluorescent intensity above baseline were considered positive. chimerism was measured using str typing of informa- tive alleles. graft failure was defined as the absence of neutrophil engraftment days from ducbt or loss of ucb chimerism by day without malignant relapse. ucb dominance was defined as . % contribution to hematopoiesis by a single ucb unit at day . s poster session i results: patients with hla-ab against ucb unit ( ), ucb unit ( ) or both ucb units ( ) were identified. no differences in cell doses, viability or baseline characteristics were noted between patients with/without hla-ab. the presence of hla-ab was asso- ciated with an increased risk of graft failure (hla-ab against either ucb unit: or . , %ci . – . , p . ; hla-ab against both ucb units: or . , . – . , p . ). neu- trophil engraftment was delayed in the presence of hla-ab (median vs. days, p . ) and fewer patients engrafted platelets in the presence of hla-ab ( . % vs. %, p . ). hla-ab against ucb unit was associated with ucb unit dominance (or . , %ci . – . , p . ), while hla-ab against ucb unit was associated with a non-significant trend toward ucb unit dominance (or . , %ci . – . , p . ). overall survival was inferior in the presence of hla-ab against ucb unit (p . ) or both ucb units (p . ), but not with hla-ab against ucb unit only. conclusions: in dubct, the presence of hla-ab increases the risk of graft rejection, prolongs time to engraftment, predicts ucb dominance and is associated with inferior outcome. hla-ab screen- ing should be incorporated into ucb unit selection strategies in ducbt. ex vivo treatment of hematopoietic stem cells

identified (north, ). ft was shown to enhance the engraftment potential of hscs from mu- rine bone marrow (mbm) or human umbilical cord blood (hcb) in murine engraftment models through an increase in proliferation, survival, migration and homing after a brief ( to hr) ex vivo treat- ment (north, ; north, ; hoggatt, ; north, goessling, zon, unpublished data). we further optimized the ex vivo hcb incu- bation protocol using whole genome expression arrays and deter- mined that hsc-containing cell products should be incubated with mm ft for hrs at �c to obtain the optimal response. in addition, we observed that ft induces similar gene expres- sion changes in hbm- and mobilized peripheral blood-derived cd cells. subsequent functional studies demonstrated that in keeping with increases of up

calcium-induced ros generation during ischemia triggers mptp- dependent cell death during reperfusion lea k. seidlmayer, vanessa v. juettner, lothar a. blatter, elena n. dedkova. rush university medical center, chicago, il, usa. impairment of mitochondrial function is a central event of ischemia- reperfusion (i/r) injury leading to tissue damage and cell death. we studied the relationship between mitochondrial ca þ overload, reactive oxygen species (ros) generation, opening of the mitochondrial permeability transition pore (mptp) and cell death in rabbit ventricular myocytes exposed to simulated i/r. changes in mitochondrial ca þ ([ca þ]m) were measured with x-rhod- , ros generation with mito-sox red, mptp opening as mitochondrial calcein red release, and cell death as lactate dehydrogenase release. i/r was induced by exposing cells to glucose-free tyrode solution containing mm -deoxyglu- cose and mm nacn, ph . , followed by superfusion with standard tyrode solution. no cell death was observed after min of ischemia despite a signif- icant increase in [ca þ]m, ros and mptp opening, however cell death in- creased significantly after min of reperfusion. the ca þ uniporter blocker ru partially prevented [ca þ ]m increase and completely abolished ros generation and cell death when applied during i/r, however application of ru only during reperfusion did not protect from cell death. scavenging ros with superoxide dismutase mimetic mntbap or antioxidant trolox pre- vented reperfusion-induced cell death. blocking mptp during ischemia by cyclosporine a or depletion of mitochondrial inorganic polyphosphate did not provide protection against cell death during reperfusion, but instead led to increased mitochondrial ros accumulation. however, inhibiting mptp opening during reperfusion with cyclosporine a attenuated cell death. we con- clude that mptp-dependent cell death during reperfusion is mediated by ca þ- dependent ros generation during ischemia. moreover, our data suggest that mptp opening during ischemia could serve as ros escape pathway from mitochondria and thereby attenuate mitochondrial ros accumulation and ros-mediated cell damage during subsequent reperfusion. -plat dynamic measurement of ca d -induced changes in organelle-specific redox microdomains david m. booth , balázs enyedi , miklós geiszt , péter várnai , györgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary. multiple interactions between ca þ -signalling and reactive oxygen species (ros) production are thought to exist and be of both physiological and patho- physiological relevance. however, until recently, the study of ros in the con- text of ca þ-signalling has been hampered by ros probes limited in both specificity and targeting. to measure ros in discrete subcellular domains, we compared the genetically-encoded ratiometric h o sensor hyper with the redox de-sensitized derivative sypher to control for non-specific changes. these probes, targeted to the er lumen, er membrane (cytosolic face), cyto- sol, mitochondrial matrix and outer membrane (omm) and the ip -receptor, are positioned to assess redox changes at a local level. in resting conditions, the er lumen showed > -fold increased hyper ratio compared to the outside of the er membrane, bulk cytosol and mitochondrial matrix and omm. in the er lumen, ip -linked ca þ -mobilization induced a prounounced, downward shift in hyper ratio, whereas little or no change was detected in other compart- ments. in permeabilized cells, mitochondrial ca þ-overload was accompanied by substantial increase in h o detected in the matrix and at the omm. these data demonstrate that redox environments within individual cellular compart- ments constitute a complex and dynamic interrelationship with the concentra- tion of free ca þ . the er lumen is highly oxidized and exhibits profound decreases in h o concommitant with ca þ -release. interestingly, these changes are not transmitted to the outer leaflet of the er membrane or to other compartments. mitochondria resist redox changes under moderate stimulation, however, during mitochondrial ca þ-overload and collapsed membrane poten- tial, strong h o generation is detectible in the matrix and at the mitochondrial surface. the ros generated and detected at locations immediately apposed to ca þ -transport proteins, such as the ip -receptor, may modify their function at a local level and contribute to the feed-forward cycle of ca þ -dysregulation and subsequent cell death. -plat er-mitochondrial ultrastructure in the liver of normal and ethnaol-fed rats gyorgy csordas , david mankus , antony anil noronha , jan hoek , carmen mannella , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, wadsworth center, albany, ny, usa. chronic alcohol consumption causes severe pathology in liver, associated with altered metabolism and reduced atp production. liver mitochondria isolated from alcohol-fed animals show decreased capacity for electron transport and atp synthesis, impaired calcium handling, and increased ros. in parallel, the endoplasmic reticulum (er) also shows increased ros and a stress re- sponse. the close correlation between defects in mitochondria and er is matched by recent evidence of the functional integration of cellular responses (including calcium signaling) involving these organelles. to evaluate the ultra- structural basis of alcohol-induced changes, we performed transmission elec- tron microscopy and electron tomography studies of rat liver. hepatocytes showed a large number of mostly round mitochondrial cross sections, which oc- cupied ~ % of the cytoplasmic area. the cell cytoplasm in chronic ethanol- fed ( months) condition exhibited reduced particle density, indicative of cell swelling, and contained large lipid vesicles. the mitochondria were generally intact but showed narrower intermembrane spacings within cristae and at the organelle periphery, consistent with low-scale matrix swelling. in both control and ethanol-fed conditions, mitochondria were typically surrounded by exten- sive er, with cisternae sometimes sandwiched between neighboring mitochon- dria. in one case, er was prominent at a site of mitochondrial fusion/fission. as previously reported, regions of close er-mitochondrial association ( - nm) contained numerous ‘‘tethers’’ between outer mitochondrial membranes (omm) and adjacent er. while individual tethers were discernible, dense granular material (including ribosomes) within omm-er interfaces interfered with accurate quantitation of tethers. however, membrane spacings could be readily measured. it was found that the mitochondrial surface in close associ- ation with er was significantly reduced in the chronic ethanol-fed condition as compared to control ( . % vs. %). this might be expected to cause reduced calcium signaling between er and mitochondria in liver after chronic alcohol ingestion. -plat mitochondrial nm -h /ndpk-d is multifunctional: intermembrane cardiolipin transfer linked to apoptosis uwe schlattner ,

in the mitochondrial intermembrane space. the well established function of the en- zyme is phosphotransfer activity as a nucleoside diphosphate kinase (ndpk), using mitochondrial atp to regenerate nucleoside triphosphates. nm -h is further known to strongly bind in vitro to anionic phospholipids, mainly cardi- olipin, and in vivo to inner mitochondrial membranes. we show here that such protein/lipid complexes inhibit ndpk activity but are necessary for nm -h to function in selective intermembrane lipid transfer. nm -h -deficient hela cells expressing either wild-type nm -h or a membrane-binding deficient mutant were analyzed by membrane fractionation and lc-esi-ms. data revealed that wild-type nm -h increased cardiolipin content in the outer mitochondrial membrane as compared to mutant enzyme. this correlated with higher susceptibility of wild-type enzyme expressing cells to rotenone-induced apoptosis as seen by increased annexin v binding, elevated caspase / activity and stimulated release of cytochrome c into the cytosol. molecular modeling of nm -h binding with cardiolipin reveals potential intermembrane transfer mechanisms. we propose that nm -h acts as a lipid-dependent mitochondrial switch with dual function, allowing either for phosphotransfer or for cardiolipin transfer, with a role in apoptotic signaling. https://core.ac.uk/display/

occupation resulting from urbanization and mainly agricultural activities (lepsch, ). the change in land use from native vegetation to areas occupied by agriculture, pasture, and urban areas (moraes et al., ) has promoted changes in the pattern of biophysical variables, causing silting of reservoirs and water courses, loss of fertile soils (assis et  al., ), and finally contributing to soil erosion processes. soil erosion is a serious global environmental problem that can cause great damage to society idesia (chile) volumen , nº  , junio, and the environment. the erosion process is a phenomenon that may occur through millions of years, causing impacts and transformations in the topography of the surface soil and alteration in sedimentary rocks (ismael et al, ). preventive measures are necessary to ensure that there are no increases in the areas affected by erosion, which could possibly increase the risk of food shortages for the population depending on agricultural production (zanata, ). g e omo r p holog y c a n m a ke i m p o r t a nt contributions to the study and planning of urban and rural areas, because development has occurred at an accelerated pace and often does not obey the natural characteristics and limitations of the environment (christofoletti, ). considering the importance of knowing and seeking measures for erosion control, geomorphological analysis and geoprocessing techniques have become relevant in these studies. with the use of thematic mapping, it is possible to identify erosive features and areas prone to erosion and also to facilitate analysis of the natural or anthropogenic environmental variables that incur erosion. in conjunction with this type of analysis, it is important to verify or elaborate measures of control (nascimento, ; silva and machado, ). geographic information systems (gis), together with geoprocessing techniques, are an important technique for environmental studies with constant integration and updating of spatial and alphanumeric data. they also allow analysis of phenomena at different scales and simulation of situations and environmental planning for decision making (pina, ; zanata, ). in view of the above, this study aimed to evaluate soil erosion vulnerability in the southern region of the meia ponte watershed, goias, brazil, considering two situations: natural and anthropic cover conditions. material and methods this study was carried out in the southern part of the meia ponte river watershed, partially covering municipalities in the state of goias (figure  ). the climate of the region is classified as type aw (tropical subhumid) according to koppen-geiger classification. it has a rainy season in the winter figure  . geographic location of the municipalities and the southern part of the meia ponte, goias hydrographic watershed. soil erosion vulnerability in the southern part of the meia ponte watershed, goias, brazil and occasional drought. the average rainfall is mm (alvares et al., ). between october and april, the rainy season, there is an increase in the possibility of new erosion and the expansion of existing erosion because water erosivity tends to be more intense. for the analysis, we used remote sensing data providing several parameters: lithology, soil class, slope, rain intensity, vegetation index, vicinity of roads and land use, and occupation. the cartographic bases of the lithology and the classes of soils were made available by the state system of geoinformation (sieg, ). soil altimetry data were obtained through topodata (inpe, ), available in letters ( th to th, letter to the millionth), accessed through the national institute of space research. slope information was generated using the terrain altimetry data. precipitation data were obtained from the meteorological station registered under number of the national meteorological institute, which is under the responsibility of the state university of goias (campus morrinhos), located at latitude . ° s, longitude . ° w, and with an altitude of m. the rainfall intensity mapping was performed using annual precipitation data. the land cover and normalized difference vegetation index (ndvi) maps were obtained through images from the landsat- satellite (orbit /point ) with passage on january , , obtained from the inpe image catalog ( ). google earth images served as an aid for identifying land use and occupation. from the maps generated in the physiographic characterization of the study area, the final map was developed by integrating the lithology, soil class, slope, rain intensity, vegetation index, proximity of roads, and land use data. all of the information was analyzed in qgis software (qgis development team, boston, usa). for the determination of the variables that represent risks from erosion, multicriteria analysis was used through the relationship between the use and occupation of the soil in the southern portion of the meia ponte watershed. for each variable, we established a scale of weights according to erosive susceptibility for natural and anthropogenic environments. for the generation of areas susceptible to erosion, weights and variables proposed by silva and machado ( ) were adopted. to generate the final map of susceptibility, the variables were organized in matrix files and weights were assigned to the variables according to the following equations: a) natural erosive susceptibility (l × ) + (s × ) + (d × ) + (r × ) + (vi × ) , (equation ) where l is lithology, s is soil class, d is declivity, c is rainfall intensity, and v is vegetation index. b) anthropic erosive susceptibility (l × ) + (s × ) + (d × ) + (r × ) + (v × ) + (pp × ) + (su × ), (equation ) where l is lithology, s is soil class, d is declivity, c is rainfall intensity, v is vegetation index, pv is proximity of pathways, and su is soil use. for the components of each map, grades to were assigned according to characteristics that tend to favor the formation of erosive processes. for the elaboration of the maps with weights, it was necessary to convert the data into vector files and reclassify the images. the variables were adopted using the methodology proposed by assis et al. ( ) and adapted from silva and machado ( ). the final maps were converted into vector files for quantification of area and calculation of the percentage of each class of erosive vulnerability. results and discussion the mapping allowed the characterization of the southern part of the meia ponte river watershed in relation to geomorphological factors. the analyzed variables allow understanding of the aspects of the region in terms of agricultural fitness and areas susceptible to erosive processes with anthropic or natural action. the lithological formation of the southern part of the meia ponte river watershed presents aspects of having low influence on degradation, considering the areas classified as high and very high (figure  a). because the soil in this area is classified as latosol, the analyses allowed us to determine that the erosive susceptibility is to a greater extent classified as very low but classified as high or very high in other small portions of the area (figure  b). latosols are more resistant to the idesia (chile) volumen , nº  , junio, action of surface runoff due to their good permeability and drainage (valle junior et al., ). the declivity of the terrain presents classes of very low, low, medium, and high erosive susceptibility, considering that the slope is classified as low in most of this area (figure  c). this can be attributed to the predominance of relief being smoothly curled toward the banks of the streams. another factor that influences erosion susceptibility as a function of slope is areas located in hills top, with slopes ranging from to % (saraiva et al., ). the shape of the terrain constitutes a qualitative variable, and from its geometry, effects are attributed that can be ordered according to their intensity, while being passive about considering the values of vulnerability to soil loss (valeriano, ; silva neto, ). because the average precipitation in the region varies from to mm per year (oliveira and sousa, ) with good spatial distribution, low susceptibility to erosive processes was observed, avoiding new erosive processes (figure  d). the ndvi revealed that the vigor of the vegetation was low in most of the area but very low, medium, and high in some regions (figure  e). the areas that had high values of ndvi were areas in which the impact caused by the force of drops of precipitation was reduced beneath the soil surface, thus reducing the velocity of water flow and minimizing the removal and transport of aggregates. high values of ndvi also indicate high vigor of vegetation, which minimizes direct contact of precipitation particles with soil and thereby reduces the effects of laminar surface runoff (guerra, ). the absence of vegetation cover makes the soil more vulnerable to inclement weather processes, causing the processes to act more intensely on these areas and thereby weaken them (guerra, ). in the areas near highways, the influence for susceptibility was classified as high. as the distance from highway increased, erosive susceptibility decreased (figure  f). intense vehicle traffic tends to contribute to intensification of erosion processes. thus, the opening of highways is a contributing factor of erosive susceptibility (amaral et al., ). soil use was the factor that contributed most to erosive susceptibility, especially when there figure  . reclassification of variables for susceptibility to litology (a), soil class (b), declivity (c), rainfall intensity (d), vegetation strength (e), proximity of pathways soil (g), and landsat image , composition r g b (h). soil erosion vulnerability in the southern part of the meia ponte watershed, goias, brazil was exploitation through agricultural activities. this land use was identified as very low, low, and average (figure  g). variables such as declivity, soil type, and land use should be considered more important variables than terrain forms, because the latter is a qualitative variable in the dynamics of erosive processes (silva neto, ). the natural erosive susceptibility was classified as medium or low in the largest portion of the watershed (figure  a). however, in the north- central area of the watershed, the natural erosive susceptibility was classified as high or very high. the map of anthropic erosive susceptibility revealed changes in the natural landscape of the southern part of the meia ponte river watershed due to the processes and higher frequency of land use change and occupation by agricultural areas and pastures (figure  b). the main economic activities in these areas were dairy farming and soybean, corn, and sugarcane cropping. all of these activities require intense use of soil, which increases erosive susceptibility. among these agricultural activities, land use with pasture is considered to be the activity that most contributes to increased risk of erosive susceptibility (valle junior et al., ). the areas of natural susceptibility (figure  ) were concentrated in areas with medium and high susceptibility classes. anthropogenic susceptibility was mostly concentrated in medium and low classes. by means of these indicators, it can be affirmed that the anthropic action has greater influence on the erosive susceptibility of the hydrographic watershed of this study. conclusions the use of multicriteria analysis with gis tools allowed the combination of qualitative and quantitative variables for erosive susceptibility. in the southern part of the meia ponte river watershed, the anthropic factor had greater influence. the factors that increased the susceptibility class in certain areas were soil use and occupation, low vegetation index, and high slope. the southern part of the meia ponte river watershed has medium natural erosive susceptibility in most of the study area. this study and the mapping of the southern part of the meia ponte river watershed will serve as a basis for actions aimed at watershed planning, promote discussion of the erosive vulnerability of the region, and assist in management of the region through actions aimed at sustainable development and recovery and the prevention of the emergence of new erosion. figure  . map of the natural erosive susceptibility (a) and anthropic (b) for the southern part of the meia ponte watershed, goias, . figure . percentages of areas in the classes of natural and anthropic erosive susceptibility of the southern part of the meia ponte watershed, goias, . idesia (chile) volumen , nº  , junio, alvares, c.a.;

intestinal malrotation; congenital anomaly background small bowel neoplasms are a rare form of cancer in the united states, with * , estimated new cases and estimated deaths per year. although the small bowel comprises % of the total surface area of the al- imentary tract, small bowel cancer comprises only . % of estimated new cases of alimentary tract cancers per year. another rare finding in adults is intestinal mal- rotation (im). a review of cases at the massachusetts general hospital found only confirmed diagnoses of im in adults for a -year period. in adults, im is often asymptomatic and found incidentally. we pres- ent a unique case of a -year-old male who presented with both duodenal cancer and incidental small bowel malrotation with associated radiological studies, pa- thology report, and a review of literature. presentation of case the patient is a -year-old caucasian male who initially presented with melanotic stools and anemia requiring mul- tiple blood transfusions. he had a medical history of hyper- tension, hyperlipidemia, chronic kidney disease, and a myocardial infarction that resulted in a cardiac stent place- ment. during his workup for anemia, he underwent an esophagogastroduodenoscopy (egd) and colonoscopy. his colonoscopy revealed no worrisome lesions in the colon. egd revealed a large malignant appearing mass – cm in size just adjacent to the ampulla, which was biop- sied. pathology analysis returned as invasive moderately differentiated adenocarcinoma. he had a computed to- mography to further delineate the mass and to assist with operative planning, which showed thickening of the duode- num as well as a partial malrotation at the third and fourth portions of the duodenum such that the ligament of treitz failed to cross the midline (fig. ). laboratories including serum tumor markers, carcinoembryonic antigen (cea) and carbohydrate antigen - (ca - ), were within normal limits. owing to his biopsy proven duodenal ade- nocarcinoma, its proximity to the pancreatic head, and the apparent structural anomalies, the patient was recommen- ded to undergo surgical resection through a pancreatico- duodenectomy. his imaging was carefully reviewed preoperatively, and the partial malrotation was noted. the patient was prepared for his whipple resection. surgical findings the patient was taken to the operating room for an open pancreaticoduodenectomy. upon exploration, the department of surgery, jefferson pancreas, biliary, and related cancer center, thomas jefferson university, philadelphia, pennsylvania. *address correspondence to: deepika koganti, md, department of surgery, jefferson pancreas, biliary, and related cancer center, thomas jefferson university, walnut street, suite , philadelphia, pa , e-mail: koganti.deepi@gmail.com ª william t. li et al. ;

it was found on the right side and inferior to its typical location. in addition, the presence of malrota- tion in the setting of significant mesenteric adipose tissue warranted that a longer portion of his jejunum be resected to yield sufficient mobility of the retained proximal jeju- num to allow for a tension-free anastomosis of the jejunum to the pancreas remnant and biliary tree. the pa- tient had normal positioning of the mesenteric arteries, which facilitated normal dissection of the pancreas around the superior mesenteric vein (smv) and superior mesen- teric artery (sma). however, the presence of considerable mesenteric fat and bowel malrotation provided signifi- cant, although overcomable, challenges to our operation. the pancreaticojejunostomy, hepaticojejunostomy, and gastrojejunostomy anastomoses were completed without incident. the specimen was sent off to pathol- ogy analysis and the frozen section analysis revealed a duodenal adenocarcinoma, with all resection margins being negative for malignancy. postoperative care postoperatively, the patient experienced transient delir- ium and developed an international study group for pancreatic fistula (isgpf) grade b pancreatic leak that was drained percutaneously. he was discharged to a rehabilitation facility on postoperative day . pathological findings the pancreaticoduodenectomy specimen contained a . · . · cm exophytic tan pink to red firm granular mass within the duodenum, * cm from the proxi- mal gastric resection margin. the mass was adjacent to a normal ampulla of vater. upon sectioning, the mass grossly appeared to extend into the muscularis propria but did not involve the underlying pancreatic parenchyma. there was no dilation of the pancreatic duct. the mass was a moderately differentiated adeno- carcinoma of the duodenum with focal invasion of the subserosal fatty tissues. a microscopic neuroendocrine tumor was also identified within the duodenal wall. it was well differentiated, low grade, and mm in greatest dimension. all regional lymph nodes recovered were negative for metastatic disease. all resection mar- gins were also negative for neoplasm. the final staging of the duodenal adenocarcinoma was t n m . molecular testing a pan-cancer -gene mutation panel of the specimen was performed. analysis showed a g v mutation of the kras gene, as well as a t>g nucleotide change in fig. . a ct scan without iv contrast showed generalized esophageal wall thickening and mild duodenal (marked by ‘‘d’’) wall thickening (b). the duodenal sweep does not cross the midline (a–c), consistent with a malrotation. there is no obstruction identified. the transverse colon evaluation was limited due to motion blur. the smv (marked by ‘‘v’’) is anterior and to the right of the sma (marked by ‘‘a’’), as would be found normally. eus performed showed a duodenal mass in the second portion of the duodenum that measured – cm. ct, computed tomography;

are cytoprotective and inhibit cell death. the mechanisms associated with these distinct effects are not entirely clear. however, the effect of hydrophilic bile acids seems to be related with the blockage of a series of processes that converge on mitochondrial damage. bax is a pro-apoptotic protein that belongs to the superfamily of the bcl- proteins and is involved in mitochondrial pore formation. submicellar concentrations of cytoprotective bile acids have been shown to modulate bax concentration in mitochondria, suggesting that these molecules may interact directly with the protein. in this study, our objective was to evaluate the affinity of bile acids to recombinant bax protein, making use of fluorescence spectroscopy (fret and fluorescence anisotropy), as well as fluorescence correlation spectroscopy (fcs). our results show that the cytoprotective bile acids udca and tudca associate with recombinant bax protein with high affinity, while the cytotoxic bile acid dca only seems to be able to adsorb to the protein with much lower affinity. notably, the bind- ing site for udca seems to be located in a hydrophobic pocket of the protein. this interaction could be responsible for the disruption of bax translocation to the mitochondrial outer membrane in the presence of udca and/or tudca. supported from fct/portugal (projects ptdc/qui-biq/ / and reci/ctm-pol/ /

initial characterization of the imacs, different di-bromocarbazole derivatives with anti-apoptotic function have been developed and tested in several mouse models of brain injury and neurodegeneration [ - ]. owing to the increased therapeutic potential of anti-apoptotic di-bromocarbazole de- rivatives, we sought to expand our knowledge of the mechanism of action of these small molecule inhibitors. we investigated the kinetics of mac inhibi- tion in mitochondria from wild type, bak, and bax knockout cell lines using patch clamp electrophysiology, fluorescence microscopy, elisa, and quantita- tive western blot analyses. our results show that imacs work through at least two mechanisms: ) by blocking relocation of the cytoplasmic bax protein to mitochondria and ) by disassembling bax oligomers in the outer membrane. a comparison of the inhibitory effects over channel conductance and cyto- chrome c release suggests that the imacs interacted with both bax and bak with similar kinetics. interestingly, wild type mitochondria were more suscep- tible to inhibition than the bak or bax knockouts. a quantitative western blot analysis showed that wild type mitochondria had lower steady state levels of bak, which suggests an uneven stoichiometry of the mac components. -pos board b tyrosine phosphorylation of mitochondrial ca d uniporter regulates mitochondrial ca d uptake jin

philadelphia, pa, usa. mitochondrial ca þ has a critical role for balancing cell survival and death. ca þ influx into mitochondrial matrix is mediated primarily by the mitochondrial cal- cium uniporter (mcu). however, the signaling pathways that regulate mcu channel functions via post-translational modifications of mcu are completely unknown. here we show that adrenergic signaling induces mcu tyrosine phos- phorylation and accelerates mitochondrial ca þ uptake in cardiac cells. adren- ergic signaling induces activation of proline-rich tyrosine kinase (pyk ) and translocation into the mitochondrial matrix; enhancing the interaction between pyk and mcu, which subsequently accelerates mitochondrial ca þ uptake via pyk -dependent mcu tyrosine phosphorylation. mcu contains tyrosine res- idues ( in the n-terminus, in the pore-forming region, in transmembrane do- mains and in the c-terminus), which are conserved across all eukaryotic species. among them, only of these tyrosine residues (y at n-terminus, y , and y at c-terminus in mouse mcu) remained as potential phosphor- ylation candidate sites for protein tyrosine kinases using phosphorylation predic- tion programs. we mutated these tyrosine residues to phenylalanine and generated non-phosphorylation mimetic mcu mutants (mcu-yfs). we confirmed that only two tyrosine sites were phosphorylated in response to adren- ergic stimulation in situ using cell lines stably expressing mcu-yfs. in addi- tion, overexpression of these mcu-yfs failed to increase mitochondrial ca þ uptake in response to cytosolic ca þ elevation by thapsigargin, whereas wild- type mcu transfection dramatically accelerates mitochondrial ca þ uptake compared to non-transfected cells. in summary, mcu contains pyk -specific

natl.cer.cardiovasc.ctrwakabayshi, suita, japan. dysregulation of ca þ homeostasis in cardiomyocytes often results in heart fail- ure. identifying molecular targets that regulate cardiomyocyte survival is of ther- apeutic importance. neuronal ca þ -sensor- (ncs- ) is an ef-hand ca þ - binding protein, which is important for excitable cell functions. we previously found that ncs- -deficient (ncs �/�) mice had excess neonatal mortality (circ. res. ).the aim ofthe present study isto examinewhether ncs- plays beneficial roles in cardiac survival during stress and the possible mechanisms un- derlying these effects. neonatal mouse ventricular myocytes orwhole hearts from wild-type (wt) and ncs �/� mice were subjected to stressors, and the resistance to stress was evaluated. ncs �/� mouse hearts were more susceptible to stress induced by oxidative impairment and ischemia-reperfusion injury. stress- inducedactivationofphosphatidylinositol -kinase (pi k)/akt signaling, a major survival pathway, was substantially reduced in the ncs �/�group, and overex- pressionofncs- ortheconstitutiveactive formofakt increased the survivalrate of ncs �/� myocytes. cellular atp levels, as well as mitochondrial respiration rates (both basal and maximal o consumption) were significantly depressed in ncs �/� myocytes; especially with oxidative stress. furthermore, intracellular ca þ handling was more easily dysregulated in stressed ncs �/� myocytes than wt myocytes. since ncs- levels were increased by stress, the data suggest that ncs- is a survival-promoting factor, which is upregulated by stress stimuli. interestingly, however,supra-physiological ncs- expression was toxic to cells. taken together, our data suggest that moderate ncs- expression during stress promotes cardiomyocyte survival by maintaining proper ca þ handling, which is required for activation of akt survival pathways and mitochondrial function. -pos board b initiation of electron transport activity and a decrease of oxidative stress occur simultaneously during embryonic heart development gisela beutner, george a. porter, jr. pediatrics, university of rochester medical center, rochester, ny, usa. mitochondria in early embryonic hearts are not thought to produce atp, yet they do produce reactive oxygen species (ros) that regulate myocyte differen- tiation. to assess changes in atp and ros generation in the developing heart, we measured mitochondrial oxygen consumption, the activity of the complexes (cx) and of the electron transport chain (etc), etc supercomplex assem- bly, and ros in embryonic mouse hearts. at embryonic day (e) . , mitochon- drial etc activity and oxidative phosphorylation (oxphos) are not coupled, even though the etc complexes are present. we show that cx- is able to accept electrons from the krebs cycle, but enzyme assays that specifically mea- sure electron flow to ubiquinone or cx- show no activity at this early embry- onic stage. at e . , mitochondria appear functionally more mature; etc activity and oxphos are coupled and respond to etc inhibitors. in addition, the assembly of highly efficient respiratory supercomplexes containing cx � , � , and � , ubiquinone, and cytochrome c begins at e . , the exact time when cx- becomes functional activated. at e . , etc activity and oxphos of embryonic heart mitochondria are indistinguishable from adult mitochon- dria. in contrast, generation of reactive oxygen species (ros), as measured with amplex red, is high at e . and drops significantly by e . , coinciding with activation of the etc. in summary, our data suggest that between e . and e . dramatic changes occur in the mitochondria of the embryonic heart, which result in a decrease of ros generation and an increase in oxphos due to the activation of cx- and the formation of supercomplexes. -pos board b the stoichiometry between micu and mcu determines the different mitochondrial ca d uptake phenotypes in heart and liver melanie

r d tobias frederico · giovanni salmè · michele viviani foreword received: december / accepted: december / published online: february © springer-verlag this special issue of few-body systems collects original efforts of the community in the field of “relativistic description of two- and three-body systems in nuclear physics” (october – , , ect∗). while we were completing the editorial and reviewing processes, we were shocked by the sad news that our outstand- ing colleague prof. john alexander tjon, suddenly passed away on september in bilthoven, the netherlands. for his great achievements and leading role, tjon has to be considered one of the “fathers” of modern few-body physics. he was a skilled and innovative scientist, with an outgoing and cheerful personality. he was extremely interested not only in various physics matters, but also in the lives, expectations, and fortunes of his colleagues and collaborators working in the same field. we have met him several times, especially at the conferences on few-body physics. just spending a few minutes with john was sufficient to appreciate his acuteness and sensitiveness. the research activity for extending the realm of investigation of the accurate non relativistic approaches, by including, possibly in a non perturbative way, the fulfillment of general properties, as the poincaré invari- ance, or even full covariance by dealing with antiparticle degrees of freedom, has been greatly influenced by his creative ideas. his interests covered a wide range of topics, from the calculations of the three-body faddeev equations, to the bethe–salpeter equation investigated both through three-dimensional reductions and the advanced and original application of the feynman–schwinger approach, always taking into great account the phenomenology. his scientific journey could be ideally started from the solution of the faddeev equations for the three-nucleon bound state, by using local two-body interactions (different from the stan- dard and simplified choice of separable interactions, mainly used at that time). this work quickly became a benchmark in the few-body community. the next steps, driven by the advent of accurate experiments on the electromagnetic interactions of very light nuclei at high momentum transfers, were the investigation of possible relativistic generalizations of the faddeev equations and the quasi-potential equations for generating solutions of the bethe–salpeter equation for the two-nucleon system. noticeably, he was the first to apply the feynman–schwinger representation for comparing ladder and generalized ladder sums in scalar field the- ories, providing a numerical demonstration of the relevance of crossed ladder diagrams in nonperturbative calculations. in the s and s, he investigated the relativistic treatment of the proton scattering by nuclei, and by exploiting his previous researches on the nucleon–nucleon interaction, he was able to shed light on t. frederico ita, são josé dos campos, brazil g. salmè (b) infn, sezione di roma, rome, italy e-mail: giovanni.salmeg@roma .infn.it m. viviani infn, sezione di pisa, pisa, italy t. frederico et al. the theoretical basis of the potential adopted in the relativistic calculations of that process. among his latest interests, of particular relevance was the very intriguing experimental result obtained at the thomas jefferson national accelerator facility, on the ratio between the electric and magnetic form factors of the proton, in sharp contrast with the values extracted from the slac data. he brightly noticed that the standard description in terms of one-photon exchange could be inadequate, and moving beyond the born approximation, he per- formed, with several co-workers, calculations of the two-photon exchange amplitude, obtaining a remarkable reduction of the discrepancy between new and old data. in his latest paper, he dealt with the same issue, but for the electric form factor of the pion. from this short description of the scientific life of tjon, one can immediately realize that the few-body community has been strongly influenced by his activity, and many of the topics discussed in the present ect∗ conference are just the continuation of the original ideas laid out by john in his seminal works. as a matter of fact, on the one hand, there already exists a number of challenging experimental puzzles (e.g., the neutron-deuteron analyzing power at low-energy or the detailed behavior at high momentum transfer of the electromagnetic deuteron form factors); on the other hand, new experimental facilities are forthcoming (as the approved gev upgrade of the electron accelerator at the thomas jefferson national accelerator facility) and this makes desirable the relativistic treatment of the nuclear systems involved in the proposed experiments. in view of this, the compelling motivation for organizing the ect∗ conference has been to set up an appropri- ate place for both discussions and cross-fertilizations between the non relativistic few-body community and the relativistic one. indeed, this motivation, fully in line with the john’s scientific legacy, is reflected in the editorial choice of putting mini reviews close to research papers, pointing to the fruitful interaction between experts in the different topics and younger colleagues, in order to widen their expertise, and to acquaint them with the most accurate and/or recent approaches. finally we would thank the people, who made it possible to organize the conference and to disseminate what has been achieved. first of all, we are pleased to express our gratitude, for both the financial support and the warm and generous hospitality, to the “european centre of theoretical studies in nuclear physics and related areas”, in trento. in particular, we acknowledge prof. achim richter, director of ect∗, the scien- tific board, and the staff. secondly we are very indebted to few-body systems, that offered the possibility of publishing this special issue, with a particular mention of the passion, the continuous help and advice of dr. bernard bakker, editor in chief. last but not least, we would like to warmly acknowledge all the partic- ipants, since, thanks to them, the discussions and the presentations were alive and fruitful, and this issue has come into the world. foreword << /ascii encodepages false /allowtransparency false /autopositionepsfiles true /autorotatepages /none /binding /left /calgrayprofile (gray gamma . ) /calrgbprofile

serious impairments in symptoms, functional status, qol, and work/productivity. however, patients who discontinued sc biologic therapy have sig- nifi cantly worse symptom scores, physical functioning, and activity impairment com- pared with those currently being treated. both fi ndings indicate there is still an unmet medical need in ra patients. pms utility and quality of life of patients with

antipolis cedex, france, nicox, sophia antipolis, france, european health economics, speracedes, france objectives: to estimate changes in quality of life (sf ) and utility (sf ) in patients treated with naproxcinod, naproxen or placebo for weeks, and to explore the effect of different disease measures on utility. methods: sf was available from international ph clinical trials in patients with knee or hip osteoarthritis comparing doses of naproxcinod ( and mg bid) to naproxen ( mg bid) and placebo. effi cacy was based on the pain, function and composite scales of the womac™ osteoarthritis index. co-morbidity measures included hypertension (ht) which increases with nsaid therapy, body mass index (bmi) and diabetes. changes in sf and individual sf domains were compared between the groups using anova and dunett’s -sided test. the effect of the womac™ indices, bp, bmi and diabetes on utility scores was explored using multiple regression analysis. results: all sf subscales except mental health as well as utility changed signifi cantly from baseline for all groups, and were correlated with changes in the womac™ indices (p . ). the change in the active groups was signifi cantly better than placebo for pain and physical function ( . ), but not signifi cantly different between treatments. however, absolute changes in utility, pain, physical function and general health were generally larger for naproxcinod mg than naproxen mg by around %. utility scores correlated signifi cantly with womac™, and patients with high bmi and bp or diabetes had lower utility scores and worse womac™ indices. increase in utilities were larger for patients with mg naproxcinod than for the other groups. conclusions: the slightly larger utility and quality of life changes with naprox- cinod mg despite a similar effect as naproxen on womac™ may be explained by a different side-effect profi le and a neutral blood pressure effect. pms an assessment of self reported outcomes in a nationally representative sample of elderly person diagnosed with rheumatoid arthritis rajpura jrjp j st. john’s university, fresh meadows, ny, usa objectives: to utilize webtv technology as a tool to measure hrqol in elderly persons having rheumatoid arthritis (ra) in a nationally representative sample and to describe their socio-demographic characteristics, medication use and other treat- ment choices. methods: a cross- sectional online survey research design. random digit dialing (rdd) survey procedures were used to draw a sample of elderly arthritic individuals from us households across states. a subsample of individu- als previously diagnosed with ra completed sf- v survey, as part of a larger study. eight sf- domain scores and physical and mental component summary (pcs and mcs) scores were computed and compared with cross-sectional norms for general us population. results: compared to the general population, our study sample per- formed poorly with respect to all the sf- domains except mental health (mh) and social functioning (sf) domains. ra is more prevalent in whites ( %) and males reported higher scores for all the eight sf- domains than females. about % of the sample reported the use of at least one available otc arthritic medication; % of the sample was taking prescription drugs, while about % reported having used natural/herbal remedies for arthritis. a signifi cant difference (p . ) was found between males and females with respect to only pcs scores. age was found to correlate negatively (p . ) with pcs and mcs summary measures, particularly for indi- viduals years and older. conclusions: webtv is an effective survey administra- tion tool for measuring hrqol. as expected, elderly perform poorly on three of the sf- domains (pf, rp, bp) having the most physical factor content. prescription drug use is fairly prevalent and use of otc medications and other forms of treatment is popular in the population under study. pms the effect of lifestyle choices on the risk of impairment in rheumatoid arthritis patients: an analysis of aerobic exercise and cigarette smoking shah a , plumb j , brawer r , tang b thomas jefferson university, philadelphia, pa, usa, centocor ortho biotech, inc, horsham, pa, usa objectives: through data analysis we will examine and identify the lifestyle factors that impact clinical outcomes of rheumatoid arthritis (ra) patients. methods: patients’ self-reported data was collected from the ra patient survey, an internet survey of ra patients. we studied the effects of aerobic exercise ( minutes a day per month), and cigarette smoking on ra patients. sign and symptom scores for morning stiffness, fatigue, and pain are defi ned from (no symptom) to (severe symptom) within the survey. the health assessment questionnaire (haq) was used to measure functional status scores ( – ). quality of life was measured by the mental component score (mcs) and physical component score (pcs) of the short-form (sf- ). productivity was measured by the work productivity and activity impairment (wpai) scale. there were no non-ra controls included in the study. results: a total of respondents were included in the analysis patients exercised and patients smoked cigarettes. the average age was . years and average ra duration was . years. patients’ mean mcs and pcs scores in the exercise ( . , . ) and non-smoking groups ( . , . ) were signifi cantly higher, than in the non- exercise ( . , . ) and smoking groups ( . , . ). overall work and productivity impairment was . % (exercise) versus . % (non-exercise), and . % (smoking) versus . % (non-smoking). signs, symptoms, and haq scores were signifi cantly better in the exercise and non-smoking groups (all p . ). conclusions: ra patients who exercise regularly have higher quality of life scores and clinical outcomes. those that smoke cigarettes have lower quality of life scores and higher symptom/ haq scores suggesting that this habit may be detrimental to their clinical outcomes. these results suggest that these lifestyle choices infl uence the overall risk of impairment in ra patients. pms is the health utilities index valid and

for health research, portland, or, usa, abbott laboratories, parsippany, nj, usa, united biosource corporation, bethesda, md, usa, leiden university medical center, leiden, netherlands objectives: qalys are an important outcome used in cost-effectiveness analysis. the health utilities index mark (hui- ) is a self-reported measure covering attri- butes of health status. our objective was to assess construct validity and responsiveness of hui- in ankylosing spondylitis (as). methods: data were derived from the adalimumab trial evaluating long-term effi cacy and safety in as (atlas). we speci- fi ed a priori hypotheses regarding the direction and magnitude of associations expected between overall and single-attribute hui- scores and other health status and quality of life measures—sf- , asqol, bath as functional index (basfi), bath as disease activity index (basdai), and patient’s global assessment (pga). using baseline data, we calculated correlation coeffi cients and interpreted them via guidelines suggested by guyatt for negligible, weak, moderate, and strong associations. responsiveness was assessed by calculating standardized response means (srms) of hui- scores from baseline to week for patients meeting the minimum clinically important differences (mcid) for the asqol ( . ). responsiveness analysis was limited to patients with -week hui- scores. results: a total of of the patients enrolled in atlas were included in the analysis. mean age was years, . % were male, and mean duration of as was years. correlation coeffi cients between hui- scores and other instruments confi rmed . % of the a priori hypothesis, with an additional . % being under- or over-estimated by only one category. results of responsiveness analysis demonstrated that there were signifi cant differences in overall hui- (srm . ) and most single-attribute change scores for patients whose changes were greater than the asqol mcid vs. those whose changes were mcid. conclusions: these results suggest that hui- constructs are related to similar constructs in other measures, as expected. this study provides evidence of cross-sectional and longitudinal construct validity of the hui- for deriving utility scores for as patients. pms validation of the multi-attribute health utility (mahu) derived from a computer adaptive instrument, cat- d-qol, in osteoarthritis

the lattice hadron physics collaboration to allow lattice qcd theorists to treat the computational facilities located at the two sites as a single meta-facility. the prototype lattice portal provides researchers the ability to submit jobs to the cluster, browse data caches, and transfer files between cache and off-line storage. the user can view the configuration of the pbs servers and to monitor both the status of all batch queues as well as the jobs in each queue. work is starting on expanding the present system to include job submissions at the meta-facility level (shared queue), as well as multi-site file transfers and enhanced policy-based data management capabilities. . the meta-facility concept the next generation of computers for lattice calculations and other grand challenge type nu- merical simulation problems will be constructed with multi-teraflops computing capabilities. such machines dedicated to a particular grand chal- lenge problem may not be geographically located at a single site. the thomas jefferson national accelerator facility and the mit laboratory for nuclear science have undertaken a joint project to develop a meta-facility for lattice physics cal- culations at a geographically dispersed facility. a “meta-facility” for lattice physics will consist of a set of tools and utilities that allow for the effi- cient distribution of of data and computing tasks among multiple lattice gauge facilities. the goals ∗support provided through the u.s. department of en- ergy cooperative agreement de-fc - er †member, lattice hadron physics collaboration ‡poster presenter §this work was supported by the u.s. department of energy contract de-ac - er , under which the southeastern universites research association (sura) operates the thomas jefferson national accelerator fa- cility of the meta-facility will provide a central location for users to submit and monitor these jobs, collect and distribute data generated from these comput- ing activities, and status of the overall status of the hardware interconnected to the meta-facility. the full implementation of the meta-facility will have the capability of providing a primary routing mechanism to provide users with the abil- ity to run jobs at one of several sites according to the resources currently available at any given time. at each site, there will be a batch system that accepts jobs from the central routing queue. a distributed batch system at each site will queue the job(s) sent to each site and control the exe- cution of the jobs on the machines at that site. the distributed batch system at each site will also communicate with the central routing queue pro- viding job status and control information to the routing queue. . the present jlab-mit facil- ity at the present time, jlab and mit have devel- oped an initial set of web-based tools and utilities that have been installed at both sites. this ini- tial software deployment will become part of the design toward an eventual full implementation of a meta-facility at both sites. these web based tools have installed to monitor the clusters of machines at both jlab and mit. these machines currently have a mix of different capabilities and configurations. jefferson lab presently has two clusters oper- ational. the first cluster consists of xp nodes from compaq. the xp is a bit alphaa processor ( mhz)with a mb l cache and kb on chip cache, a mhz sdram subsystem and integrated gb wide- ultra scsi ( rpm) disk subsystem with dual independent / bit pci buses. eight of the xp nodes are have myrinet cards installed, the nodes are connected to a myrinet switch. the second cluster consists of dual processor up from api labs. the up- systems have dual mhz processors with mb caches, mb memory, and an gbide disk ( rpm) at mit, the are twelve compaq es ma- chines. each es machine has four ev- mhz alpha processors and gbyte of memory in an smp configuration within each box. the twelve es s are connected by both myrinet hardware and fast ethernet. there are also ad- ditional intel based pcs that serve as backup, file and batch servers at this site. this entire set of machines is positioned behind an intel based front-end machine. this front end machine serves the functionality of a firewall and as a repository for the web-based tools and utilities the current capabilities of the present sys- tem allow users at either the jlab or mit sites to launch and monitor batch jobs and examine batch queue parameters and machine status. the jlab site also has the capability to allow users to browse the tape file catalog and initiate file trans- fers from to and from the jlab tape storage fa- cilities. at the present time there is a certificate server operational at jlab with the capability of issuing a personal web certificate for enhanced se- curity for users submitting jobs to that site. . future plans and enhance- ments the present configuration that is operational at jlab and mit has demonstrated a proof of concept. the batch system execution queues at both the jlab and mit sites operate properly and a web based link has been established be- tween both sites that provides information on the status and batch jobs running on all clusters. the project will be moving forward with two ma- jor upgrade tasks scheduled over the next several months. - at the present time, batch job submission via the web is limited to the jlab site. web services for batch submission of jobs at the mit site will be installed in the fall of . - tape transfers at both jlab and mit involve a two-stage process because of the front-end ma- chines acting as firewalls at both sites. work is ongoing to develop full tape file transfer capabil- ity at both sites after these immediate tasks have been com- pleted and are operational, there are several longer term activities planned for development and implementation of a fully functional meta- facility. at both the mit and jlab sites, only the exe- cution queues have been configured in the batch queuing system at each site. the ultimate goal is to develop and install a separate node in the meta-facility that will be dedicated to the func- tionality of a routing queue. the routing queue would not be attached to any of the individual clusters in the meta-facility but would rather view all of the execution queues on every cluster at all sites throughout the meta-facility. the routing node will act as a separate communications and traffic manager. users would only submit jobs to the node that was running the

revolution was a historical event that immediately provoked numerous and very different reactions in the new as well as the old world. it can be regarded as an ideological laboratory for enlightenment actors, in which they tested how far their principles of liberty, equality, fraternity, and the right to revolt against oppression extended. their reactions were tightly linked to their personal interests and convictions and their relationship to the political system they inhabited. this study analyzes the different points of view of two personalities with a significant influence on the events and the spirit of their time: the famous traveler and prussian scientist alexander von humboldt ( – ) and the sandra rebok virginian statesman thomas jefferson ( – ). emphasis will be on their perception of the incidents in saint-domingue and their impact on the outer world, the way they referred to these events in their writings and their personal correspondence, and finally the position they took regarding the new situation of this caribbean island. i. introduction la révolution de saint-domingue, la première révolution menée par une société noire et esclave, constitua un événement dont l’impact fut immédiat dans la région. la population esclave y trouva un exemple de ce qu’elle était capable d’obtenir. les habitants blancs s’aperçurent, quant à eux, du résultat auquel pouvait aboutir le colonialisme établi par eux et, en particulier, l’inhumain sys- tème d’esclavage tellement répandu à cette époque. la conséquence principale fut un grand sentiment de peur parmi les blancs, mais elle fut aussi à l’origine de réflexions sur la manière de prévenir de semblables développements dans la région, c’est-à-dire, sur la création de mesures ou des réformes pour obtenir un système d’esclavage moins inhumain, plus efficace et surtout plus stable. ces événements provoquèrent ainsi de nombreuses réactions et des réponses différentes, non seulement au nouveau monde, affecté d’une façon plus im- médiate, mais aussi sur l’ancien continent. la révolte de saint-domingue (ou de haïti, nom pris par le pays lors de sa déclaration d’indépendance à partir de ) attira ainsi beaucoup l’attention, car elle réunissait des thèmes divers très discutés à cette époque et sujets à polémique: le colonialisme comme institution européenne étendu au reste du monde, les mouvements indépendantistes qui se développèrent en réaction, le système de l’esclavage, les buts et les résultats de la révolution française ainsi que la réalisation ou la mise en pratique des idéaux humanistes du siècle des lumières. on peut dire que la révolution haïtienne se présentait comme une provocation idéologique pour les hommes éclairés, un test pour voir jusqu’où vont leurs principes de liberté et d’égalité ainsi que le droit de se révolter contre une situation d’abus de pouvoir. les différentes réactions étaient donc étroitement liées à des intérêts et à des convictions personnelles comme aux relations entretenues avec le système politique dans lequel ils vivaient. la présente étude analyse les regards différents de deux personnages qui ont eu une influence remarquable sur les événements et sur l’esprit de l’époque: le la révolution de haïti vue par deux personnages contemporains fameux voyageur et scientifique prussien alexander von humboldt ( – ) et l’homme d’état virginien thomas jefferson ( – ). nous nous intéressons à la manière dont ils perçurent la révolution de saint-domingue et son impact sur le reste du monde, à la manière dont ils y firent référence dans leurs écrits ou dans leurs lettres et à la position ou l’action qu’ils développèrent concernant la nouvelle situation de cette île des caraïbes. après son expédition à travers l’amérique espagnole durant les années à , alexander von humboldt, accompagné de son collègue français aimé goujand bonpland, visitait les États-unis du mai au juin , ou il ren- contra plusieurs fois le président américain thomas jefferson et les membres de son cabinet. les motivations et les intérêts de humboldt pour sa visite aux États-unis reposaient sur deux intentions. tout d’abord, il voulait connaître personnellement jefferson, connu pour être un scientifique et un philosophe. ensuite, après avoir voyagé durant des années à travers les colonies espagnoles du nouveau monde et observé les différentes sociétés coloniales, dont cer- taines possèdent des caractéristiques critiquables, humboldt était intrigué par l’opportunité de se familiariser avec un pays libre en amérique. durant son séjour aux États-unis, humboldt resta principalement au con- tact d’hommes politiques et de l’élite scientifique du pays. il passa tout d’abord une semaine à philadelphie, où il s’entoura principalement de membres de la american philosophical society. ensuite, il voyagea à washington, où il resta du er au juin. il visita également alexandria et mount vernon durant cette période. humboldt rencontra jefferson la première fois probablement le juin, et durant ce séjour, il fit la connaissance de james madison, gilbert stuart, william thornton et albert gallatin. lorsque humboldt retourna à philadelphie, il y resta encore dix jours avant de repartir pour l’europe. antérieurement à cette première rencontre, humboldt écrivit une lettre à jefferson et exprima son admiration et respect pour son intellect développé, son travail, et ses idées libérales. influencé par son identification à des idéaux du mouvement indépendant américain, ainsi qu’aux buts de la révolution française, humboldt fut très impressionné par la forme démocratique de la société américaine, qu’il percevait comme une possibilité pour d’autres régions américaines ainsi que pour des nations européennes. jefferson, pour sa part, pensa également que humboldt pouvait lui apporter quelque chose de particulièrement intéressant. la documentation et les cartes des archives coloniales espagnoles contenant des données jusqu’alors inconnues sandra rebok sur les frontières entre les États-unis et le nouvel espagne pourraient en effet avoir beaucoup de valeur. cette information pourrait être très importante à cause du fait de l’acquisition récente du territoire de louisiane. humboldt se conforma au désir de thomas jefferson de voir cette documentation, lui permet- tant de connaître les dernières informations géographiques et statistiques de la nouvelle espagne. a partir de cette brève entrevue, une amitié de longue date se développa entre les deux hommes, marquée par des échanges d’idées dans leur correspondance, ainsi que dans leurs ouvrages. l’attitude de alexander von humboldt sur le colonialisme est connue grâce à cette unique expédition dans les colonies espagnoles. dans ces régions il put appréhender le système colonial avec tous ses inconvénients et ses problèmes pour la population opprimée ou rendue esclave, juste avant que les mouvements indépendantistes n’apparaissent dans ces territoires. dans ses nombreux ouvrages, et plus encore dans ses journaux de voyage, il offre des élaborations scientifiques détaillées sur cette exploration, mais aussi des réflexions plutôt critiques sur les diverses facettes du système colonial. en raison de ses propres convictions humanistes, humboldt n’était pas du tout d’accord avec cette institution, comme il l’exprime dans ses journaux: d’où vient ce manque de moralité, d’où viennent ces souffrances, ce malaise dans lequel tout homme sensible se trouve dans les colonies européennes? c’est que l’idée de la colonie même est une idée immorale, c’est l’idée d’un pays qu’on rend tributaire à un autre, d’un pays dans lequel on ne doit parvenir qu’à un certain degré de prospérité, dans lequel l’industrie, les lumières ne doivent se répandre que jusqu’à un certain point [ . . . ] tout gouvernement colonial est un gouvernement de méfiance. on y distribue l’autorité non selon que la félicité publique des habitants l’exige, mais selon le soupçon que cette autorité peut s’unir, s’attacher trop au bien de la colonie, devenir dangereux aux intérêts de la mère patrie. ces lignes témoignent des convictions de humboldt, connu comme un farouche adversaire du système d’esclavage, sa réaction aux événements qui se produisirent à haïti nous intéresse donc tout particulièrement. la révolution de haïti vue par deux personnages contemporains le regard de thomas jefferson sur ces événements nous fournit un point de vue issu du nouveau monde. avec lui on voit la réaction du prési- dent des États-unis—c’est-à-dire de la première république indépendante de cet hémisphère—au moment crucial de la révolution haïtienne, et dans les premières années après la déclaration d’indépendance de haïti en . dans sa fonction d’un des founding fathers et auteur de la déclaration d’indépendance des États-unis, jefferson était convaincu de la nécessité des futures révolutions non seulement dans les régions coloniales d’amériques, mais aussi dans les monarchies absolutistes en europe. il était, d’une certaine façon, considéré comme un promoteur ou inspirateur de ces mouvements. ses préoccupations se manifestent dans ses écrits, notamment dans sa vaste correspondance. en parlant de la situation tumultueuse en hollande et france, dans une lettre à tench coxe, le juin , il constate: this ball of liberty, i believe most piously, is now so well in motion that it will roll round the globe, at least the enlightened part of it, for light & liberty go together. it is our glory that we first put it into motion & our happiness that being foremost we had no bad examples to follow. pourtant, jefferson était aussi un grand propriétaire d’esclaves; il profitait donc lui aussi de cette institution inhumaine. l’esclavage aux États-unis fut cependant pour lui et durant sa vie une telle préoccupation, qu’il présenta plusieurs propositions pour le supprimer. la révolution menée par les noirs à saint-domingue était un test crucial pour le droit à la révolution de chaque peuple, droit qu’il défendait lui-même. il est finalement intéressant de voir jusqu’à quel point ces deux personnages représentent le regard du nouveau continent sur ces événements comparé à celui de l’ancien continent. c’est de notoriété publique que humboldt et jefferson étaient des supporteurs des idéaux éclairés existants au début de la révolution française, même s’ils n’étaient pas du tout d’accord avec ses réper- cussions sanglantes. ils partageaient donc un point de départ idéologique com- mun; pourtant, comme on le verra par la suite, les deux hommes appartenaient à des contextes sociopolitiques différents, qui déterminaient sans doute leur argumentation et leur action. sandra rebok ii. deux regards différents sur la révolution haïtienne alexander von humboldt en général, on peut dire que alexander von humboldt représentait la tradition du siècle des lumières et à plusieurs occasions lui-même reconnaît qu’il portait « les idées de dans son cœur », c’est-à-dire, qu’il conserva toute sa vie une conscience spéciale des principes fondamentaux de liberté, d’égalité et de fraternité, sur lesquels il construisit sa propre philosophie. pourtant, il faut souligner claire- ment qu’il n’a jamais approuvé l’intransigeance révolutionnaire des jacobins. la terreur de la révolution française comme les événements en haïti et d’autres révoltes d’esclaves l’inquiétaient beaucoup, si bien qu’en plusieurs occasions il avertit du danger de réactions violentes en amérique. selon les convictions de humboldt, ces réactions ne pouvaient jamais mener à la construction d’une société progressive. bien que critiquant sévèrement le colonialisme, en faisant mention des possibles conséquences qui pouvaient résulter de la situation sociale et politique de cette époque, il ne se montre en aucune façon en faveur d’une solution militaire. il rejette toute forme de révolution violente comme moyen politique. cependant il fait des propositions détaillées sur des gouvernements et des institutions établies par de possibles réformes, car il était convaincu que l’origine de beaucoup de ces problèmes se trouvaient dans l’administration: les gouvernements européens ont si bien réussi à répandre la haine et la désunion dans les colonies qu’on n’y connaît presque pas les plaisirs de la société; du moins tout divertissement durable dans lequel beaucoup de familles doivent se réunir est impossible. de cette position naît une confusion d’idées et de sentiments inconcevables, une tendance révolutionnaire générale. mais ce désir se borne à chasser les européens et à se faire après la guerre entre eux. il faut dire que humboldt était plutôt prudent dans ses commentaires en ce qui concernait la situation politique des régions qu’il visitait en amérique. comme scientifique il ne voulait pas trop se mêler de ce terrain compliqué et éviter de possibles conflits avec les autorités locales. mais c’est aussi sans doute en remerciement de l’autorisation généreuse qui lui était concédée par le roi espagnol carlos iv. dans ses journaux de voyage, on trouve également peu de commentaires explicites qui montrent son opinion sur les premiers signes de la demande de liberté dans les régions visitées. sa conviction que les colonies espagnoles pourraient être dans une situation économique beaucoup plus la révolution de haïti vue par deux personnages contemporains favorable si elles obtenaient leur indépendance vis-à-vis des intérêts financiers de la métropole, peut seulement être dérivée d’une analyse économique détaillée des statistiques du commerce. aussi à l’égard des événements en haïti, on ne trouve aucun commentaire dans la partie de ses journaux déjà publiée—un fait qui peut paraître étonnant, car l’expédition de humboldt était justement réalisée dans les années qui cor- respondent à la proclamation de liberté et d’indépendance de l’état de haïti en . un espoir subsiste néanmoins de découvrir des documents. ulrike leitner a récemment découvert pages avec des annotations inconnues faites par humboldt sur cuba, document trouvé à la biblioteka jagiellonska de cracovie. ce matériel portant le titre « isle de cuba. antilles en général » n’a pas encore été publié—et n’a donc malheureusement pu être consulté pour cette recherche. selon michael zeuske, il contient aussi des informations en relation avec saint-domingue. dans les oeuvres publiées par humboldt, on ne trouve pas de traité ou de longues réflexions sur les événements en haïti qui puissent révéler son attitude à l’égard de ce sujet, seules quelques références à saint-domingue avec de brefs commentaires sur l’influence possible ou le danger que cela pouvait avoir pour le reste de l’amérique coloniale. les deux ouvrages qui contiennent ces remarques sont les deux essais régionaux sur la nouvelle espagne et celui sur cuba; en revanche on n’en trouve aucune trace dans son récit de voyage voyage aux régions équinoxiales du nouveau continent. dans le premier essai, celui sur la nouvelle espagne, il mentionne les «  événements tragiques  » de la révolution de saint-domingue et regrette qu’apparemment la peur de ces événements prenne le pas dans la société sur les considérations morales, les principes philanthropes et ceux de justice qu’ils auraient pu susciter: [ . . . ] tant il est vrai que la crainte des maux physiques agit plus puissamment que les considérations morales sur les vrais intérêts de la société, ou les principes de la philanthropie et de justice, si souvent énoncés au parlement, à l’assemblée constituante et dans les ouvrages des philosophes! vers la fin de cette oeuvre il prévoit les futurs changements en amérique et se montre en cette occasion plutôt optimiste, car il voyait dans ces incidents haïtiens une influence positive sur la réduction du trafic de la population noire. sandra rebok a part ces commentaires, c’est surtout dans son traité sur cuba qu’il intègre les résultats de la révolution haïtienne dans sa propre argumentation. il faut d’abord rappeler que humboldt avait consacré beaucoup d’effort à la lutte contre l’esclavage, spécialement à cuba mais aussi aux États-unis. il proposa de nom- breuses réformes pour réduire et finalement supprimer cette institution atroce, qui contredisait pour lui tous les idéaux du siècle des lumières. parfaitement conscient que ses arguments humanistes n’emportaient pas la conviction de tous, il fait porter son argumentation sur le terrain économique. son étude sur cuba, et en particulier le chapitre sur l’esclavage, contient de nombreux avertissements sur ce qui pourrait se passer à cuba, au cas où on ne saurait pas interpréter les signes de haïti: si la législation des antilles et l’état des gens de couleur n’éprouvent pas bientôt des changements salutaires, si l’on continue à discuter sans agir, la prépondérance politique passera entre les mains de ceux qui ont la force du travail, la volonté de s’affranchir et le courage d’endurer de longues privations. cette catastrophe sanglante aura lieu comme une suite nécessaire des circonstances, et sans que les noirs libres de haïti s’en mêlent aucunement, sans qu’ils abandonnent le système d’isolement qu’ils ont suivi jusqu’ici. il continue son argumentation en critiquant la position de la population blanche, qui selon lui, n’était pas consciente de l’urgence de résoudre ce problème: toute similarité d’action de la part des noirs leur paraît impossible; tout change- ment, toute concession accordée à la population servile, un signe de lâcheté. rien ne presse: l’horrible catastrophe de saint-domingue n’a été que l’effet de l’inhabileté des gouvernants. on voit dans ces deux citations que humboldt considérait les incidents en haïti comme « l’horrible catastrophe » ou comme une « catastrophe sanglante ». avec ce jugement il ne se réfère pas aux résultats de ce mouvement, car il le considère comme « une suite nécessaire des circonstances », mais au processus violent qui leur a donné lieu et qui devait être évité à tout prix. comme on l’a déjà vu, il s’exprime toujours contre une solution violente, et croit en revanche profondément à la force des idées éclairées et humanistes. par conséquent, il valorise fortement la reconnaissance de l’état de haïti par le gouvernement français: la révolution de haïti vue par deux personnages contemporains espérons que la force de l’opinion publique, le progrès des lumières, l’adou- cissement des mœurs, la législation des nouvelles républiques continentales, et le grand et heureux événement de la reconnaissance d’haïti par le gouvernement français, exerceront, soit par des motifs de prévoyance et de crainte, soit par des sentiments plus nobles et plus désintéressés, une influence heureuse sur l’amélioration de l’état des noirs dans le reste des antilles, dans les carolines, les guyanes et le brésil. humboldt expose très clairement l’influence de cette révolution sur la situation des esclaves dans d’autres régions. pour lui ce thème est tellement important qu’il le reprend à la fin de son essai sur cuba et finit cet ouvrage avec des réflexions au sujet de haïti. il rappelle la situation de haïti comme « centre de grandes agitations politiques », qui menaçait de susciter dans les autres îles des luttes sanglantes que humboldt réprouvait: ces menaces et ces craintes n’ont heureusement pas été accomplies; l’orage s’est apaisé dans les lieux mêmes qui l’ont vu naître, et une population noire libre, loin de troubler la paix des antilles voisines, a fait quelques progrès vers l’adoucissement des mœurs et l’établissement de bonnes institutions civiles. finalement, humboldt se montre content du développement de ce proces- sus pendant les ans qui ont suivi la première révolution de haïti, pour les habitants de cette île, mais aussi pour les hommes blancs des îles espagnoles et anglaises. il prévenait cependant d’une « funeste sécurité qui s’oppose avec dédain à toute amélioration dans l’état de la classe servile », car comme le rappelle la conclusion de son livre, « la crainte du danger arrachera des concessions que réclament les principes éternels de la justice et de l’humanité. » il ne s’agit pas d’une étude approfondie sur cette question, ni de considérations sur les causes et les conséquences de ces événements, mais plutôt d’une application des résultats de la révolution haïtienne sur la situation de cuba. de cette manière, il inclut ces incidents, et la peur qu’ils ont provoquée parmi la population blanche, dans sa lutte contre l’esclavage, c’est-à-dire, qu’il les intègre à sa démonstration. selon zeuske, la clé de l’intérêt de humboldt pour l’esclavage ne se trouve ainsi pas directement à cuba, mais dans la révolution sandra rebok de saint-domingue. pour cela, les réflexions de son essai cubain peuvent être entendues comme un appel aux personnes éclairées et instruites parmi l’élite cubaine qu’il avait connue personnellement dans cette île, comme par exemple francisco de arango y parreño ( – ). thomas jefferson dans le cas de thomas jefferson, son attitude au sujet des événements de haïti est beaucoup plus complexe et davantage conditionnée par son statut de prési- dent des États-unis. son opinion personnelle, sur ce point, fait se rejoindre différents thèmes très importants à ses yeux: l’institution de l’esclavage, sa rela- tion à la population noire, la révolution comme moyen politique, ses idées pour l’avenir du nouveau monde, etc. ce sont ces différents aspects qui font du sujet haïtien un sujet assez compliqué pour lui. de plus, étant donné qu’il occupait dans les années – la tête du gouvernement, son opinion ne pouvait pas seulement être guidée par ses convictions personnelles, mais était en fonction d’un réseau d’intérêts divers. ces années virent de grands changements dans la politique intérieure et extérieure de son pays, changements qui eurent également une influence sur la position de jefferson. par conséquent, pour comprendre l’évolution de la politique de jefferson à l’égard de haïti, il est nécessaire de la replacer dans son contexte historique. a partir de , avec les premiers signes de cette révolte, jefferson commença à s’inquiéter du possible danger haïtien. sa réaction fut d’abord d’émettre des propositions pour une émancipation graduelle, comme on peut le voir dans une lettre de destinée à james madison où il parle du danger d’une insurrection inspirée par saint-domingue et où il conclut: « against this there is no remedy but timely measures on our part to clear ourselves by degrees of the matter on which that lever can work. » comme président, jefferson proposa un accord des puissances contre le régime de toussaint louverture, mais quand il devint conscient des vastes ambitions de bonaparte en amérique, il changea d’avis et refusa de tenir sa promesse d’aider les français. pendant les années de guerre de – , il suivit officiellement une politique de neutralité, mais en réalité cette posture cau- sait des problèmes aux français, car ils ne disposaient pas sur place des moyens suffisants pour cette expédition militaire et dépendaient de l’aide des américains. cette « neutralité » constituait, de fait, une aide considérable au régime haïtien. la révolution de haïti vue par deux personnages contemporains de cette manière, jefferson encourageait l’indépendance de saint-domingue à l’égard de la france, mais il refusa néanmoins en de reconnaître le nouveau régime, craignant l’influence de la révolution des esclaves haïtiens sur ceux qui se trouvaient aux États-unis. il proclama même un embargo sur le commerce avec l’île caraïbe, qui n’avait donc pas de légalité, jusqu’en . quand, avant la proclamation d’indépendance haïtienne en juin de , le général en chef de l’armée de saint-domingue, jean-jacques dessalines, lui envoya une lettre pour essayer de renouer les relations commerciales avec les États-unis et continuer les relations cordiales établies par john adams, il préféra ne pas répondre et de cette manière refusa l’opportunité d’établir des liens entre les deux pays. cette posture contredit son attitude comme secrétaire d’état en , quand il défendait la reconnaissance du gouvernement révolutionnaire français. elle est, de plus, en opposition avec les principes de la déclaration d’indépendance américaine en qui fixait le droit des peuples à changer un gouvernement oppresseur: that whenever any form of government becomes destructive of these ends, it is the right of the people to alter or to abolish it, and to institute new government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. [ . . . ] but when a long train of abuses and usurpations, pursuing invariably the same object evinces a design to reduce them under absolute despotism, it is their right, it is their duty, to throw off such government, and to provide new guards for their future security. un point très important pour comprendre l’attitude de jefferson en ce qui concerne haïti concerne donc les rapports entre les États-unis et la france, et plus particulièrement, les intérêts de la république nord-américaine dans cette relation. au sujet de l’embargo, l’opinion publique était divisée sur l’opportunité et le bien-fondé d’entretenir des relations commerciales avec cette île. les sympa- thies de jefferson pour napoléon et le peuple français l’inclinaient à renoncer aux principes de neutralité qu’il avait énoncés comme un des axiomes de la politique nord-américaine. mais cette neutralité était par ailleurs très avantageuse pour les États-unis, car entre et ils étaient le plus important fournisseur de l’île, surtout en produits alimentaires. un autre aspect qui influe sur les relations avec la france, et par conséquent sur le sujet haïtien, concerne les intérêts du sandra rebok gouvernement nord-américain pour la louisiane et après l’achat de cette région en , ses ambitions pour obtenir la floride. l’embargo a été renouvelé d’une façon systématique jusqu’en , c’est-à-dire, le moment où les perspectives d’acquisition de la floride devenaient plus certaines. après cette date, le soutien de france ne lui paraissait plus indispensable, donc les commerçants pouvaient reprendre leur fructueux trafic avec haïti. les réactions des propriétaires d’esclaves du sud des États-unis sont un autre facteur dans la politique de jefferson face à haïti, surtout après les conspirations d’esclaves dans la région de richmond en et (gabriel plot et easter plot). la découverte de préparatifs pour une insurrection pro- voqua une grande peur parmi la population blanche de virginie, et déclencha en réaction une campagne de terreur contre les rebelles ou ceux soupçonnés tels. la loyauté de jefferson envers les planteurs de virginie était très forte; il pouvait comprendre leur peur et leurs phobies raciales—surtout qu’il était lui aussi un planteur des États du sud—et il se sentait donc obligé de défendre leurs droits. cela se manifeste dans une lettre à rufus king, où jefferson soulignait la vulnérabilité du sud de son pays, en disant: the course of things in the neighboring islands of the west indies appears to have given a considerable impulse to the minds of the slaves in different parts of the us. a great disposition to insurgency has manifested itself among them, which, in one instance, in the state of virginia broke out into actual insurrec- tion. this was easily suppressed, but many of those concerned, (between . & . i believe) fell victims to the laws. le président était obligé de prendre en considération les intérêts des expan- sionnistes, surtout après l’achat de la louisiane. sa politique face à l’esclavage dans les nouveaux territoires, et le fait qu’en il ne s’opposa finalement plus à l’extension de cette institution dans cette région, est un autre facteur lié à son attitude à l’égard de l’île caraïbe. jefferson était conscient que son attitude envers haïti n’était pas très cohérente et même plutôt ambivalente, mais souvent ses options étaient limitées et, dans autre cas, les changements dans sa politique étaient dictés par des considérations domestiques. la question de haïti montre clairement comment jefferson était la révolution de haïti vue par deux personnages contemporains tiraillé entre ses propres convictions et les conditions politiques de son époque, essayant de réconcilier les intérêts antagonistes existants aux États-unis—celui de maintenir l’esclavage dans le sud et les ambitions mercantiles du nord—pour ne pas risquer l’unité de son pays, tout en défendant les intérêts nord-américains au niveau géopolitique international. en conséquence, les convictions éclairées et les principes humanistes de jefferson se trouvaient subordonnés à des intérêts nationaux. ses convictions devaient s’effacer devant les ambitions économiques ou l’expansion de son pays. iii. analyse: le regard du vieux monde vers le regard du nouveau monde il serait très intéressant pour nous de savoir si alexander von humboldt et thomas jefferson discutèrent des événements de haïti quand ils se rencontrèrent à washington au printemps de ; malheureusement nous ne disposons pas de documents sur les thèmes qu’ils discutèrent pendant leurs réunions. il n’y a pas de référence non plus à ce sujet dans les lettres qu’ils échangèrent pendant les années suivantes, jusqu’à la mort de jefferson en , où ils commentent certains développements politiques. cela peut paraître étonnant, mais il faut savoir qu’il y a pas mal de thèmes « polémiques » comme par exemple l’esclavage, sur lesquels nous ne trouvons pas de commentaires dans leur correspondance. on peut supposer que tenant des positions très différentes en cette matière, ils préféraient éviter de se trouver dans un débat conflictuel. par contre, dans sa correspondance avec l’architecte william thornton ( – ), humboldt fait des références à l’esclavage échangeant informations et opinions. dans une lettre de juin il lui dit qu’il avait lu son mémoire sur les esclaves et dans ce contexte il se réfère à haïti où il constate que: « plus que les événements récents de s[an] domingue ont offusqué la vérité et plus il paraît du devoir de tout homme moral de replacer le problème dans son vrai jour ». afin de pouvoir comparer les positions de humboldt et jefferson, il faut d’abord être conscient des contextes différents dans lesquels ces deux personnages se trouvaient. humboldt comme scientifique pouvait approuver les buts et les résultats politiques de la révolution haïtienne—en refusant tous ses sandra rebok aspects violents—et faire état librement et publiquement de son opinion, puisque ces buts et ces résultats concordaient avec ses propres convictions humanistes. jefferson, par contre, dans sa fonction politique était obligé de réfléchir et de peser tous les conséquences de ses mesures en fonction de l’intérêt de son pays, des possibles réactions de ses adversaires, et finalement de l’influence de ses ac- tions sur les élections suivantes. humboldt regardait ainsi la révolution de haïti dans le contexte et en relation avec ses intérêts à cuba; jefferson, pour sa part, les reliait avec ses projets pour les États-unis, son intérêt lié avec la france, et particulièrement avec la situation des propriétaires d’esclaves. ces différences dans leur situation personnelle sont également évidentes dans leurs regards très distincts sur l’institution de l’esclavage. pour humboldt c’est l’antithèse de ses convictions personnelles, et à de nombreuses occasions il exprime son aversion pour cette institution inhumaine, particulièrement dans le septième chapitre de son oeuvre sur cuba qui est entièrement consacré à ce sujet. en ce qui concerne thomas jefferson ses commentaires sont assez ambivalents et souvent contradictoires, ce qui fait que le sujet a été beaucoup débattu parmi les historiens et a été source d’interprétations divergentes. son attitude évoluait avec le temps, comme on peut voir dans un grand nombre de ses lettres, dans son oeuvre notes on the state of virginia, et dans son autobiographie écrite en . a part ses premières initiatives pour l’affranchissement des esclaves et sa conviction ultérieure que cela pouvait résoudre les problèmes pour les générations futures, on peut également trouver dans ses ouvrages certaines affirmations qui peuvent être interprétées comme racistes ou supportant l’esclavage. finalement, il était lui-même un des plus grands propriétaires d’esclaves en virginie, et au lieu de l’interdire, il approuva plus tard l’expansion de cette institution dans le missouri et dans d’autres états. la complexité et la difficulté de ce sujet sont exprimées par lui dans la fameuse citation de son autobiographie: nothing is more certainly written in the book of fate, than that these people are to be free; nor is it less certain that the two races, equally free, cannot live in the same government. nature, habit, opinion have drawn indelible lines of distinction between them. humboldt pouvait voir et évaluer le système de l’esclavage d’un point de vue extérieur, puisque ni sa vie privée ni sa vie professionnelle n’étaient connectées avec cette institution. jefferson était né dans ce système et il était étroitement la révolution de haïti vue par deux personnages contemporains lié avec l’esclavage de plusieurs manières. pour lui il s’agissait d’une institution établie depuis longtemps sur laquelle était basée la vie des planteurs en virginie. les esclaves constituaient de plus une partie significative de sa richesse person- nelle et de cette façon lui assuraient ses revenus et sa liberté économique, ce qui lui permettait de se dédier à ce qui était important pour lui. la décision de supprimer l’esclavage aurait donc eu des conséquences majeures non seulement dans son futur d’homme politique, mais aussi dans sa vie personnelle. quant aux idéaux humanistes du siècle des lumières et à l’égalité des hom- mes, ils témoignent de différences remarquables entre les représentants des deux continents. de nouveau jefferson semble montrer une compréhension plus pragmatique et limitée de ses propres valeurs. il est connu—bien que beaucoup débattu—que la fameuse phrase de la déclaration de l’indépendance, « all men are created equal » n’incluait pas d’autres personnes que les hommes blancs ayant propriété de la terre. il ne s’agissait pas d’une égalité politique, sociale ou économique, mais plutôt d’un droit divin à la vie, à la liberté et par suite à la félicité. donc, c’est dans les commentaires, à caractère privé, de jefferson sur la situation de la population noire, sur le système d’esclavage en particulier, mais aussi sur sa position à l’égard des indiens d’amérique et finalement dans ses réflexions sur la révolution haïtienne, qu’il manifeste ses convictions. humboldt appliquait en revanche ses revendications éclairées à tous, comme cette citation sur l’égalité des hommes, tirée de son oeuvre kosmos, l’illustre clairement: indem wir die einheit des menschengeschlechtes behaupten, widerstreben wir auch jener unerfreulichen annahme von höheren und niederen menschenracen. es giebt bildsamere, höhere gebildete, durch geistige cultur veredelte, aber keine edleren volksstämme. alle sind gleichmäßig zur freiheit bestimmt; zur freiheit, welche in roheren zuständen dem einzelnen, in dem staatenleben bei dem genuß politischer institutionen der gesamtheit als berechtigung zukommt. en conclusion, la révolution en haïti et les différentes réactions que cet événement a provoquées dans le vieux comme dans le nouveau monde ne peuvent pas être regardées indépendamment des autres thèmes mentionnés. les réactions peuvent manifester des convictions personnelles, mais elles sont également liées à des conditions historiques et politiques ou à des intérêts privés, comme on a pu le montrer avec l’exemple de ces deux personnalités. finalement sandra rebok on pourrait dire que dans le cas présent humboldt représente une perspective plus européenne et une position plus idéaliste, tandis que jefferson était plus pragmatique; pour lui, c’était la réalité qu’il se présentait, puisqu’il s agissait de créer une société nouvelle aux États-unis et pour cela, beaucoup des aspects étaient à prendre en compte. dans la comparaison de ces deux regards il faut être conscient de la fonction différente qu’ils occupaient dans leurs sociétés respectives: humboldt comme scientifique, philosophe et autorité morale, et jefferson, comme scientifique, mais surtout comme homme politique, respons- able de l’avenir de sa jeune république. notes ce travail a été réalisé dans le cadre d’un contrat post-doctoral i p du csic. mes remerciements aux robert h. smith international center for jefferson studies à charlottesville, virginia, États-unis pour une bourse de quatre mois afin d’effectuer mes recherches à monticello. je remercie également jean-françois guennoc du centre de recherche sur la littérature de voyages (crlv, paris iv) et marie ange minh trang do cao pour leur aide linguistique. . sur ce sujet voir par exemple léon-françois hoffmann, frauke gewecke, ulrich fleisch - mann (éds.), haïti —lumières et ténèbres: impact et résonances d’une révolution (madrid: iberoamericana;

transitions in care dear sir improved coordination of care after hospitalizations is essential to decrease readmissions and costs, and most importantly, to prevent undesirable patient outcomes. changes in care plans may be lost through ineffective communication to the patient or providers, making this transition particularly critical (kripalani et al. ). third- year medical students are frequently involved in discharges though rarely have opportunities to follow patients after the hospitalization and receive little formal training in transitional care. students’ self-assessed competency in transitional care has been shown to increase after introducing curriculum designed to focus on discharge planning (bray-hall ). this study aims to assess third-year medical student perceptions of transitional care following an educational exercise. students identified a patient and completed a semi- structured telephone interview within – days after discharge to assess patients’ adherence with discharge instructions. the survey involved questions about the discharge process guiding the students to: assess the patient’s understanding of perceived need, benefit and disadvantages of the hospitaliza- tion, reconcile medications, determine adherence to home services and follow-up appointments, and ascertain if the patient returned to the ed. students were then asked to comment on their experiences in order to provide an opportunity for reflection. three independent reviewers analyzed the qualitative data from the students’ reflections for emerging themes. themes included coordination of care, empathy and patient relationships, in addition to recognition of logistical challenges in patient continuity. students articulated many components of the discharge process in which difficulties arise and noted that they were more thoughtful in preparing discharge-related documentation when they knew they would be contacting the patient. several students also high- lighted continuity of care and patient relationships as the aspects of this exercise that they found to be most valuable. this exercise serves as an innovative model for incorporating discharge planning into the curriculum of inpatient clerkships and was found to increase insight into the complexities of transitional care. transitional care is pivotal in decreasing adverse events and readmission, and we recommend that this education be incorporated into undergraduate medical training. beth careyva, lehigh valley health network, bethlehem, pennsylvania, usa.

services attract a government (medicare) rebate, but often require a patient co-payment. this public–private divide has created an ethos that private (i.e. paying) patients would not accept the

corresponding author: xiao chi zhang, xzhang @gmail.com abstract effective team building and leadership are crucial in running an effective and safe healthcare system with improved patient care and clinical outcomes. currently, there is a great demand for formal leadership training throughout the extensive medical education curriculum. we constructed an interactive team-building activity utilizing gamification-theory with the zoom game. the zoom activity requires a team of learners to organize a set of sequential images, each of which contains a “zoomed out” section from the previous image, into the correct order within a set time frame. given the unique and approachable nature of this team-based activity, we propose the following: ) to introduce the zoom game as a team-building and communication fostering exercise in undergraduate medical education and ) to assess baseline teamwork skills of first-year medical students through an immersive gaming experience. with this in mind, first-year medical students (class of ) at an urban-city medical school were enrolled in the zoom team building activity as part of their orientation. the students were randomly assigned to teams, comprising - students and two faculty facilitators per team and completed the activity in the allotted time frame. the average time to complete the zoom game was minutes, and all the teams successfully placed the pictures in the correct order. facilitators noted that the zoom game strongly encouraged friendly interactions, intercollegiate high values, mutual respect, confidence, and trust among each other. students observed take-home points such as selecting a leader, designating specific roles, and encouraging closed-loop communication. overall, the zoom activity game is an interactive, fun, and easily accessible team-building and communication fostering exercise in undergraduate medical education. further studies on the zoom game exercise would be essential to determine whether it has a continuous and enduring effect on developing team building among medical students. categories: medical education, other keywords: team building, gamification, undergraduate medical education introduction team building and leadership are two critical features in running an effective and safe healthcare system. studies have indicated that effective leadership correlates with improved patient care and clinical outcomes [ - ]. as medical students graduate to become resident physicians, they are tasked with newfound responsibilities of simultaneously managing their patient care, communicating treatment plans, and coordinating care from the nurses, techs, consultants, and supervising physicians. despite robust scientific literature supporting the importance of effective teamwork and leadership in promoting student learning, healthcare performances, and improved patient outcomes, there is still a great demand for formal open access technical report doi: . /cureus. how

) they should be first-year medical students attending thomas jefferson university. individuals who were unable to consent (e.g., due to altered mental status, dementia, or developmental delay) were excluded. we did not anticipate community attendants to be intoxicated, incarcerated, or in clinical distress during this study. all incoming first-year medical students were required to attend this activity as part of their mandatory orientation training. this study was deemed exempt from institutional review board (irb) approval by the jefferson irb. materials/personnel requirements in order to play the game, each group, consisting of - students, is required to cut out and separate a set of pictures from the zoom game (with one picture on every individual sheet). two facilitators are responsible for organizing the activity, handing out the pictures, and evaluating the team performance. detailed activity description preparation (five minutes) the facilitators first select the number of sequential pictures in play for the activity. the zhang et al. cureus ( ): e . doi . /cureus. of number of active pictures must be equal to the number of total players (a maximum of pictures). if there are fewer than players, all pictures must be in the correct sequence to avoid lapsing photographs. the picture order is then shuffled before distribution. introduction (five minutes) the facilitators explain the zoom activity to the group and then hand out the sequential pictures facedown to each participant. each participant is given a few moments to thoroughly examine his or her pictures. activity ( minutes) the group communicates with each other about the order they believe the pictures to be in without showing each other the pictures. the group is then instructed to put the pictures in order as efficiently as possible (with no information given about what the “order” is). once they believe they have put the images in order, the images are revealed sequentially to see if the order is correct. if one image is not correct, the game continues until everything is in the correct order. participants are not allowed to show each other their images but can demonstrate/describe their image through actions and words. the entire game is expected to last minutes in total. debrief ing (five minutes) after the completion of the zoom game, all players participate in a brief facilitator-led debriefing to discuss the overall observed teamwork during the activity. players are encouraged to disclose take-home points of the activity. activity evaluation following the end of the activity, the facilitators are expected to complete two separate, blinded evaluations of the participants’ leadership, preparation, participation, communication, and listening skills through the institutional jefferson teamwork observation guide (jtog) [ ]. the jtog is a validated, user-friendly, -item likert-scaled ( = strongly agree, = strongly disagree) evaluation instrument based on learner and clinician feedback for interprofessional education, primarily designed to assess teamwork [ ]. results in our activity, first-year medical students in the graduating class of at sidney kimmel medical school of thomas jefferson university, philadelphia, pa participated as part of their orientation. the students were randomly assigned to teams, comprising - students and two faculty facilitators per team. the average time to complete the zoom game was minutes and all the teams successfully placed the pictures in the correct order. the mean jtog scores were calculated based on the blinded assessment of each team’s two facilitators. facilitators noted that the zoom game strongly encouraged friendly interactions (likert score: . ), intercollegiate high values (likert score: . ), and mutual respect, confidence, and trust (likert score: . ) among each other (table ). in contrast, areas of improvement were noted in the identification of a team leader (likert score: . ), understanding the roles and responsibilities of each member (likert score: . ), and the overall activity preparation (likert score: . ). comments captured from the jtog for first-year medical students were evaluated through open-axial qualitative analysis performed by the authors, who have extensive experience with qualitative research (table ). according to the students, the primary take-home points from the zoom activity centered on the following: ) selecting a leader ) designating specific roles ) zhang et al. cureus ( ): e . doi . /cureus. of eliciting specific directions;

ics : communicate zhang et al. cureus ( ): e . doi . /cureus. of effectively with colleagues within the same profession), professionalism (p : demonstrate compassion, integrity, and respect), and interprofessional collaboration (ipc : work with other health professional to maintain mutual respect, dignity, and trust). we recognize that there were several limitations to our study. this was a feasibility study at a single medical school, assessing the baseline teamwork skills for the first-year medical students during orientation. while there are numerous published studies on teaching teamwork in undergraduate medical education, most involve case scenarios or role-playing within a non- acute healthcare setting or simulation centers with high-fidelity mannequins [ - ]. our study focused primarily on assessing and reflecting on unique aspects of teamwork and leadership of first-year medical students before they began their medical training, making it unique compared to previous studies. while the jtog was a useful assessment tool, an additional test is warranted to see how the early implementation of the zoom activity can affect the realization of epa guidelines during the students' training period. furthermore, due to a large number of students, we required a large number of facilitators to evaluate and supervise the students. additionally, more iterations and advanced statistical software will be required to calculate inter-rater reliability between the facilitators' scores in the future. conclusions the zoom activity game is an interactive and easily accessible team-building exercise that can be used to assess baseline teamwork skills of first-year medical students through an immersive gaming experience. by engaging first-year medical students in the zoom game, we were able to highlight the aspects of teamwork necessary among the students to succeed as collaborative and supportive future physicians. further studies on the zoom game exercise would be essential to determine whether it can have a continuous and lasting effect on instilling team-building qualities among medical students. additional information disclosures human subjects: consent was obtained by all participants in this study. thomas jefferson university irb issued approval not applicable. this study meets the jefferson irb exemption criteria. animal subjects: all authors have confirmed that this study did not involve animal subjects or tissue. conf licts of interest: in compliance with the icmje uniform disclosure form, all authors declare the following: payment/services info: all authors have declared that no financial support was received from any organization for the submitted work. financial relationships: all authors have declared that they have no financial relationships at present or within the previous three years with any organizations that might have an interest in the submitted work. other relationships: all authors have declared that there are no other relationships or activities that could appear to have influenced the submitted work. references . bohmer r: designing care: aligning the nature and management of health care . harvard business review press, boston, ma;

single-chain variable fragment (sfv) has been reanalyzed and demonstrated to be an aberrant heavy chain sequence. this heavy chain sequence is very close to the aberrant heavy chain sequence published by p. thammana (molecular immunology : – , ), who derived it via rt-pcr directly from the rna of the ns cell line which is commonly used as a fusion partner to construct mouse hybridomas. therefore, it is likely that the aberrant d sfv heavy chain was derived from a gene originating from the fusion partner cell line used to make the original d hybridoma and not from the heavy chain gene expressed by the b-cell precursor to this hybridoma. this aberrant heavy chain has a deletion in the framework region (fr ) leading to a frameshift in cdr and downstream regions of the heavy chain gene. in addition, there were some individual nucleotide changes, on reanalysis, that brought the heavy chain sequence even closer to that described by thammana. it should also be noted that the function of the aberrant heavy chain in the d sfv is not known. as well, the initial amino acids in the d sfv represent a portion of the vk leader sequence. the possible effects, if any, of this segment on subcellular localization and/or secretion have not been investigated. there was noted to be rather minimal binding data for the d sfv available to be reevaluated at this time, including only a single elisa for the d sfv to recombinant rev and a single binding study of the activation domain peptide of rev. comparisons to the original d monoclonal antibody are not obtainable since the characteristics of the original monoclonal antibody are not fully demonstrated at the present time. as well, complete original data dealing with anti-rev d sfv binding to peptides of rev are not available at the present time. on reanalysis, inaccuracies in the d sfv sequence were noted. d sfv on resequencing showed the following differences compared to the published sequence: t to a (aca to gca), t to s (acg to tcg), and g to a (ggt to gct). nucleotide changes which did not alter the amino acid sequence were: c to t, g to c, t to a, and t to a (numbering started at initial atg codon). a nucleotide was demonstrated to be missing at position (g) (l ), compared to the original sequence, altering the remaining amino acids (dywgqgtsvtvssakttpppvyplapgs). on reevaluation, the originally reported d sequence would connote a frameshift in the cdr of vh, but now, as resequencing revealed the missing nucleotide, the frameshift is shown not to be present. thus, d sfv is, in fact, an appropriate antibody sequence. although further studies are planned, these additional findings do not alter the previous conclusions that intracellular d and d sfvs inhibit hiv- . we regret any difficulties these inaccuracies in the original publications may have caused. authors’ correction j. virol. o n a p ril , a t c a r n e g ie m e l l o n u n iv l ib r h ttp ://jvi.a sm .o rg / d o w n

ursodeoxycholic acid (udca) and tauroursodeoxycholic acid (tudca), are cytoprotective and inhibit cell death. the mechanisms associated with these distinct effects are not entirely clear. however, the effect of hydrophilic bile acids seems to be related with the blockage of a series of processes that converge on mitochondrial damage. bax is a pro-apoptotic protein that belongs to the superfamily of the bcl- proteins and is involved in mitochondrial pore formation. submicellar concentrations of cytoprotective bile acids have been shown to modulate bax concentration in mitochondria, suggesting that these molecules may interact directly with the protein. in this study, our objective was to evaluate the affinity of bile acids to recombinant bax protein, making use of fluorescence spectroscopy (fret and fluorescence anisotropy), as well as fluorescence correlation spectroscopy (fcs). our results show that the cytoprotective bile acids udca and tudca associate with recombinant bax protein with high affinity, while the cytotoxic bile acid dca only seems to be able to adsorb to the protein with much lower affinity. notably, the bind- ing site for udca seems to be located in a hydrophobic pocket of the protein. this interaction could be responsible for the disruption of bax translocation to the mitochondrial outer membrane in the presence of udca and/or tudca. supported from

several mouse models of brain injury and neurodegeneration [ - ]. owing to the increased therapeutic potential of anti-apoptotic di-bromocarbazole de- rivatives, we sought to expand our knowledge of the mechanism of action of these small molecule inhibitors. we investigated the kinetics of mac inhibi- tion in mitochondria from wild type, bak, and bax knockout cell lines using patch clamp electrophysiology, fluorescence microscopy, elisa, and quantita- tive western blot analyses. our results show that imacs work through at least two mechanisms: ) by blocking relocation of the cytoplasmic bax protein to mitochondria and ) by disassembling bax oligomers in the outer membrane. a comparison of the inhibitory effects over channel conductance and cyto- chrome c release suggests that the imacs interacted with both bax and bak with similar kinetics. interestingly, wild type mitochondria were more suscep- tible to inhibition than the bak or bax knockouts. a quantitative western blot analysis showed that wild type mitochondria had lower steady state levels of bak, which suggests an uneven stoichiometry of the mac components. -pos board b tyrosine phosphorylation of

medicine, jefferson medical college, thomas jefferson university, philadelphia, pa, usa. mitochondrial ca þ has a critical role for balancing cell survival and death. ca þ influx into mitochondrial matrix is mediated primarily by the mitochondrial cal- cium uniporter (mcu). however, the signaling pathways that regulate mcu channel functions via post-translational modifications of mcu are completely unknown. here we show that adrenergic signaling induces mcu tyrosine phos- phorylation and accelerates mitochondrial ca þ uptake in cardiac cells. adren- ergic signaling induces activation of proline-rich tyrosine kinase (pyk ) and translocation into the mitochondrial matrix; enhancing the interaction between pyk and mcu, which subsequently accelerates mitochondrial ca þ uptake via pyk -dependent mcu tyrosine phosphorylation. mcu contains tyrosine res- idues ( in the n-terminus, in the pore-forming region, in transmembrane do- mains and in the c-terminus), which are conserved across all eukaryotic species. among them, only of these tyrosine residues (y at n-terminus, y , and y at c-terminus in mouse mcu) remained as potential phosphor- ylation candidate sites for protein tyrosine kinases using phosphorylation predic- tion programs. we mutated these tyrosine residues to phenylalanine and generated non-phosphorylation mimetic mcu mutants (mcu-yfs). we confirmed that only two tyrosine sites were phosphorylated in response to adren- ergic stimulation in situ using cell lines stably expressing mcu-yfs. in addi- tion, overexpression of these mcu-yfs failed to increase mitochondrial ca þ uptake in response to cytosolic ca þ elevation by thapsigargin, whereas wild- type mcu transfection dramatically accelerates mitochondrial ca þ uptake compared to non-transfected cells. in summary, mcu contains pyk -specific phosphorylation site(s) and pyk -dependent tyrosine phosphorylation of mcu can modulate its channel functions and regulate mitochondrial ca þ uptake. -pos board b cardioprotective roles of neuronal ca d sensor- during stress tomoe y. nakamura-nishitani , shu nakao , shigeo wakabayashi . molecular physiology, natl.cer.cardiovasc.ctr., suita, japan, cardiac physiology, natl.cer.cardiovasc.ctrwakabayshi, suita, japan. dysregulation of ca þ homeostasis in cardiomyocytes often results in heart fail- ure. identifying molecular targets that regulate cardiomyocyte survival is of ther- apeutic importance. neuronal ca þ -sensor- (ncs- ) is an ef-hand ca þ - binding protein, which is important for excitable cell functions. we previously found that ncs- -deficient (ncs �/�) mice had excess neonatal mortality (circ. res. ).the aim ofthe present study isto examinewhether ncs- plays beneficial roles in cardiac survival during stress and the possible mechanisms un- derlying these effects. neonatal mouse ventricular myocytes orwhole hearts from wild-type (wt) and ncs �/� mice were subjected to stressors, and the resistance to stress was evaluated. ncs �/� mouse hearts were more susceptible to stress induced by oxidative impairment and ischemia-reperfusion injury. stress- inducedactivationofphosphatidylinositol -kinase (pi k)/akt signaling, a major survival pathway, was substantially reduced in the ncs �/�group, and overex- pressionofncs- ortheconstitutiveactive formofakt increased the survivalrate of ncs �/� myocytes. cellular atp levels, as well as mitochondrial respiration rates (both basal and maximal o consumption) were significantly depressed in ncs �/� myocytes; especially with oxidative stress. furthermore, intracellular ca þ handling was more easily dysregulated in stressed ncs �/� myocytes than wt myocytes. since ncs- levels were increased by stress, the data suggest that ncs- is a survival-promoting factor, which is upregulated by stress stimuli. interestingly, however,supra-physiological ncs- expression was toxic to cells. taken together, our data suggest that moderate ncs- expression during stress promotes cardiomyocyte survival by maintaining proper ca þ handling, which is required for activation of akt survival pathways and mitochondrial function. -pos board b initiation of electron transport activity and a decrease of oxidative stress occur simultaneously during embryonic heart development gisela beutner, george a. porter, jr. pediatrics, university of rochester medical center, rochester, ny, usa. mitochondria in early embryonic hearts are not thought to produce atp, yet they do produce reactive oxygen species (ros) that regulate myocyte differen- tiation. to assess changes in atp and ros generation in the developing heart, we measured mitochondrial oxygen consumption, the activity of the complexes (cx) and of the electron transport chain (etc), etc supercomplex assem- bly, and ros in embryonic mouse hearts. at embryonic day (e) . , mitochon- drial etc activity and oxidative phosphorylation (oxphos) are not coupled, even though the etc complexes are present. we show that cx- is able to accept electrons from the krebs cycle, but enzyme assays that specifically mea- sure electron flow to ubiquinone or cx- show no activity at this early embry- onic stage. at e . , mitochondria appear functionally more mature; etc activity and oxphos are coupled and respond to etc inhibitors. in addition, the assembly of highly efficient respiratory supercomplexes containing cx � , � , and � , ubiquinone, and cytochrome c begins at e . , the exact time when cx- becomes functional activated. at e . , etc activity and oxphos of embryonic heart mitochondria are indistinguishable from adult mitochon- dria. in contrast, generation of reactive oxygen species (ros), as measured with amplex red, is high at e . and drops significantly by e . , coinciding with activation of the etc. in summary, our data suggest that between e . and e . dramatic changes occur in the mitochondria of the embryonic heart, which result in a decrease of ros generation and an increase in oxphos due to the activation of cx- and the formation of supercomplexes. -pos board b the stoichiometry between micu and mcu determines the different mitochondrial ca d uptake phenotypes in heart and liver melanie paillard, györgy csordás, tünde golenár, cynthia moffat, erin seifert, györgy hajnóczky. mitocare center, pathology, thomas jefferson university, philadelphia, pa, usa. mitochondrial ca þ uptake is central to oxidative metabolism and cell death signaling. the first clues to its molecular mechanism have emerged from the recent identification of the mitochondrial ca þ uniporter’s pore forming protein (mcu) as well as its regulators. among the regulators, micu shows striking a wednesday, february , co-expression and co-evolution with mcu. micu has been demonstrated to be a ca þ -sensing protein, which both sets a threshold for low ca þ concentration while it assures cooperative activation during high ca þ rises. mitochondrial ca þ uptake shows tissue specific differences and interestingly, mrna level for micus and mcus also displays tissue specificity. we set out to investigate if the stoichiometry between micu and mcu could account for the previously described differences between heart and liver in mitochondrial ca þ uptake. immunoblotting showed higher expression for all micu , micu and mcu in mouse liver versus heart mitochondria, and a . fold higher micu to mcu ratio in liver. in fluorometric measurements of mitochondrial ca þ uptake, heart mitochondria displayed a decreased threshold and lesser cooperativity compared to liver mitochondria. additionally, nad(p)h elevation was detect- able after exposure to moderate [ca þ ] elevations only in heart mitochondria. overexpression of micu in the heart using aav -micu tail-vein injection significantly increased the micu protein level without any changes of micu or mcu. this increased the micu to mcu ratio in the heart and led to increased thresholding and cooperativity, reproducing the liver-like mito- chondrialca þ uptakephenotype.viceversamicu downregulationintheliver has been shown to lower the threshold and cooperativity of mitochondrial ca þ uptake in hepatocytes. thus, heart and liver mitochondria show different levels of ca þ threshold and cooperative activation of ca þ uptake, which seem to result from differential quantitative relationship between micu and mcu. -pos board b er calcium release is tuned by mitochondrial redox nanodomains david m. booth , balázs enyedi , miklós geiszt , péter várnai , györgy hajnóczky . mitocare center, pathology, thomas jefferson university, philadelphia, pa, usa, department of physiology, semmelweis university, budapest, hungary. spatially and temporally controlled increases of h o emerge as an intracellular signal. we hypothesized that ros and ca þ interact locally, in the restricted vol- ume of the er-mitochondrial interface. these physically tethered structures host enrichments of ion transport proteins such as the ip receptor, which support elevated nanodomains of ca þ during signalling events and are sensitive to h o . we used the genetically encoded h o sensor hyper incorporated into an inducible linker system to probe the redox environment at the er- mitochondrial interface in hepg cells. we found a moderately elevated h o nanodomain which developes into a h o transient following ip receptor- mediated er ca þ release and mitochondrial ca þ uptake. pharmacological in- hibition showed that the transient was dependent upon er ca þ, mitochondrial membrane potential and functional electron transport chain. hyper measure- ments of the mitochondrial intermembrane space revealed significantly elevated h o within this volume. using electron microscopy we found that hepg mito- chondria possess a cohort of dilated cristae, which disappeared following ip - linked ca þ release. paxilline that inhibits mitochondrial bkca channels blocked the cristae reshaping and also abolished the h o transient at the inter- face. furthermore, paxilline caused suppression of the ip -linked calcium signal, whereas interface targeted killer red, a photoactivated h o source, induced sensitization to the ip -linked agonist. we conclude that the intermembrane/ cristae volume of mitochondria represents an oxidized pool fed by the electron transport chain. ca þ -uptake stimulates expansion of the mitochondrial matrix via kþ and concomitant water uptake, squeezing the oxidized volume of the cristae to the interface. here, a transient h o nanodomain sensitizes ip recep- tors to further stimulation. we demonstrate a physiological setting where ca þ release may autoregulate using mitochondrial h o released from the cristae. -pos board b reactive oxygen species (ros) suppress mitochondrial motility valentina debattisti, masao saotome, sudipto das, gyorgy hajnoczky. mitocare center, thomas jefferson university, philadelphia, pa, usa. mitochondrial distribution and transport play pivotal roles for many cellular functions, including cell differentiation, cell division to ensure proper inheri- tance, apoptosis, atp supply at the local sites of demand, ca þ buffering for intracellular ca þ homeostasis. we previously showed that mitochondrial motility (mito-motility) is regulated by the cytosolic ca þ concentration ([ca þ]c), providing the basis for a homeostatic circuit in which the organelles decrease their movements along microtubules to locally buffer high [ca þ ]c and contribute to atp supply. mito- chondria are also a major site for production and scavenging of ros that serve as both a messenger and regulator of calcium signaling and are particularly rele- vant for the control of mitochondrial function. here we tested the hypothesis that ros target mito-motility to control mitochondrial function. h c myoblast cells were transfected with a mitochondrial matrix targeted yfp and then loaded with fura , to monitor the mito-motility simultaneously with [ca þ ]c. h o ( mm) caused a decrease in mito-motility ( %) and an elevation in [ca þ ]c (from to nm) at the same time. when the cells were incu- bated in a ca þ -free medium and were pretreated with thapsigargin to prevent ca þ entry and intracellular ca þ mobilization, respectively, h o continued to inhibit the mito-motility dose-dependently without any changes in [ca þ]c. these results indicate that h o can cause suppression of mito-motility through a ca þ independent mechanism we are currently analyzing. -pos board b miro is dispensable for calcium-mediated inhibition of mitochondrial movement david b. weaver , agnieszka lewandowska , tammy t. nguyen , valentina debattisti , janet m. shaw , gyorgy hajnoczky . mitocare center, dept of pathology, anatomy and cell biology, thomas jefferson university, philadelphia, pa, usa, biochemistry, university of utah school of medicine, salt lake city, ut, usa. miro and are (rhot and ) are two highly similar gtpases that are bound to the surface of mitochondria and possess ef-hand calcium binding motifs. several groups have reported that miro is involved in mitochondrial motility and inheritance, and particularly its calcium regulation, but the roles of the two isoforms have not been established. genetic deletion of miro in mouse is lethal at birth (nguyen et al., ) and fibroblasts (mefs) derived from miro ko em- bryos show abnormal mitochondrial distribution, but the calcium-dependent in- hibition of motility is unaffected and the respiratory and calcium buffering capacities are normal. neuron-specific knockout of miro leads to progressive deficits of upper motor neuron function, however mitochondria in processes of cortical neurons from miro ko and wild-type embryos showed comparable calcium-sensitive motility inhibition. while no significant increase in miro pro- tein was observed in miro ko mefs, these data raise two possibilities: miro and are interchangeable with regard to calcium regulation of mitochondrial motility or miro is the key player in this regard. to finally resolve this question, we are in the process of generating miro ko and miro / ko cell lines. -pos board b mitochondrial fusion dynamics in the heart veronica eisner , ryan cupo , erhe gao , györgy csordás , lan cheng , jessica ibetti , j. kurt chuprun , walter j. koch , györgy hajnóczky . mitocare center, pathology, thomas jefferson university, philadelphia, pa, usa, center for translational medicine, temple university school of medicine, philadelphia, pa, usa, center for translational medicine, thomas jefferson university, philadelphia, pa, usa. heart physiology depends on oxidative metabolism that likely requires dy- namic and permanent reorganization of mitochondria by fusion and fission. to directly evaluate mitochondrial fusion dynamics in cardiomyocytes (cm), mitochondrial matrix-targeted photoactivatable gfp and dsred were intro- duced either in vitro or in vivo by adenovirus and were followed by confocal microscopy. four conditions were analyzed: to h cultured neonatal and in vitro transduced adult cm, and cm from in vivo infected rat hearts. in the latter case, cm were isolated - days after infection and were imaged promptly or - h post harvesting. neonatal cm mitochondria form a highly connected network, whereas both in vitro and in vivo transformed cultured cm displayed only some connectivity. impressively, in vivo transduced adult cm that were imaged promptly after harvesting, unveiled a significantly higher con- nectivity among mitochondria than the - h cultured adult cm. furthermore, fusion events (f.e./ square micrometers/min) were almost absent in cultured in vitro transduced cm, meanwhile in vivo transduced and cultured cm showed . . f.e./min, whereas isolated, freshly-imaged cm displayed . . f.e./min. imaging in perfused whole heart ex vivo, showed consider- able mitochondrial continuity and fusion activity in ventricular cm. to study more directly the role of cm’s contractile activity in mitochondrial fusion, cm were incubated with verapamil ( mm), that blocked spontaneous contrac- tion and partially suppressed the fusion activity of mitochondria. also, mito- chondrial fusion activity appeared to be higher after spontaneous contraction or short term field stimulation in isolated freshly-imaged cm. thus, mitochon- dria are dynamic in both neonatal and adult cm, but under culture conditions, adult cm lose mitochondrial fusion activity. this might be at least in part, because cardiomyocyte contractile activity is altered in culture and contractions likely provide some factors to support mitochondrial fusion activity. -pos board b mechanistic characterization of the thioredoxin system in the removal of hydrogen

water structure sunday, february , a -pos board b access constraints and binding energetics of a potassium channel inactivation gate gaurav venkataraman, deepa srikumar, miguel holmgren. nih, bethesda, md, usa. voltage-activated potassium (kv) channels open an intracellular gate in re- sponse to changes in transmembrane voltage, allowing k þ to permeate at rates near diffusion. in some kv channels, permeation can be interrupted by the n-terminus of the protein acting as a blocking particle, binding at the intracel- lular cavity of the channel and physically obstructing the permeation pathway. despite being tetramers, kv channels require only one bound n-terminus to inactivate. in nature, inactivation is targeted by rna editing, which converts an isoleucine of the intracellular cavity into a valine. the functional conse- quence is a large increase in unbinding kinetics. how does each ‘‘wall’’ of the cavity contribute to the increase in unbinding kinetics of a single bound n-terminus? to address this question we made con- catenated shaker heterotetramers consisting of only one free n-terminus and a single isoleucine to valine mutation at position (i v), mimicking the rna editing site in humans and rodents. surprisingly, the rate of unbinding was the same for individual i v mutations in each wall; each corresponded to a decrease in binding energy of about . rt. in fact, the binding energy de- creased linearly as a function of the number of i v mutated subunits. these results suggest that despite being tethered to a particular subunit, the single in- activation particle has sufficient freedom to interact with position of each subunit with roughly equal probability. where does this freedom come from? it is expected that the inactivation gates enter the cavity through lateral ‘windows’, similarly to k þ . can our single tethered inactivation gate enter through each of the four windows of the protein? we will address this question by making individual cysteine mutations at each window and testing the inac- tivation gate’s binding kinetics after chemical modification. -pos board b gating interactions between the cytoplasmic t domain and pore of a kv channel brian urbani, manuel covarrubias. jefferson medical college of thomas jefferson university, philadelphia, pa, usa. whereas the gating roles of the voltage-sensing and pore domains of kv channels have been extensively investigated, much less is known about the mechanisms governing the regulation of gating by the cytoplasmic t domain. previous work from this lab strongly suggests that the kv . t domain un- dergoes conformational changes directly linked to gating (j. gen. physiol., : - , ); however, the structural basis of the communication between the activation gate and the t domain has remained elusive. to tackle this problem, we applied cysteine scanning mutagenesis, voltage- clamp electrophysiology, double mutant cycle analysis (dmca) and oxidizing reagents to probe specific interactions between the cytoplasmic t domain l helix, the s -s linker and s tail. the energetic impact of the mutations on activation gating is apparently small. by comparison, the energetic impact of the mutations on inactivation gating was significantly greater. dmca of k c(l )þa c(s ) revealed a significant interaction energy ( kcal/ mol), which suggests an interaction between k in the l helix and a in s . supporting this possibility, the currents induced by k c(l )þ a c(s ) are inhibited (~ % of control) by an oxidizing agent (tbuho ), whereas the single mutants are not; and the effect is reversed by the reducing agent dtt. these results indicate the formation of a disulfide bond between the interacting side chains, which is consistent with physical interaction between k (l ) and a (s ). overall, we conclude that regulation of inactivation gating by the t domain involves a physical interaction between the t l helix and the distal segment of s . supported by nih grant r ns (mc). -pos board b is the activation gate closed in kv channel closed-state inactivation? jeffrey d. fineberg, manuel covarrubias. thomas jefferson university, philadelphia, pa, usa. kv .x channel complexes including auxiliary subunits such as dpp -s and kchip undergo preferential closed-state inactivation (csi; baehring and covarrubias, , j physiol, . : - ; fineberg et al., , j gen physiol, in press). however, the molecular basis of csi in kv .x channels remains poorly understood. a key unanswered question of this problem is whether the channel’s activation is actually closed, as csi implies. we have previously proposed that csi results when the activated channel fails to open or simply prefers to close. this hypothesis specifically suggests that the intra- cellular activation gate may adopt a stable closed conformation, even under depolarized conditions that would initially favor the activated ‘‘up’’ state of the voltage sensors. to test this hypothesis, we are exploiting the trapping paradigm previously investigated by holmgren et al. to test the state of the intracellular activation gate ( , j gen physiol, : - ). essentially, if the activation gate closes behind a quaternary ammonium (qa) blocker inside the pore, the blocker cannot exit the pore; effectively, it is trapped. we are expressing the ternary kv . /i c channels (this mutation favors trap- ping) including dpp -s and kchip in xenopus oocytes. then, in the inside- out patch-clamp configuration, we are using a computer-controlled perfusion system to deliver the qa derivative decyltrimethylammonium bromide (c ) to the bath and probe the ability of the channel’s activation gate to trap c in the closed, open and inactivated states. preliminary results show that the trapping paradigm may yield an answer to the central question of this study. if the activation gate is indeed closed during csi, c trapping will only occur when the drug is applied to the conducting channel, but no trapping of c will be observed in the closed and inactivated states. supported by nih grant r ns (mc). -pos board b water at the potassium channel gate: quantum calculations show an oscillation in water structure alisher m. kariev, michael e. green. city college of the city university of ny, new york, ny, usa. quantum calculations on the open gate and the immediately surrounding re- gion of the kv . voltage gated potassium channel show that water adopts two conformations there, one when the ion is present, and another with no ion present. an energy minimum at the gate with no ion allows an ion to enter from the solution; from the gate it repels an ion in the channel pore cavity into the selectivity filter (essentially the ‘‘knock-on’’ mechanism). the pore cavity minimum can then be occupied by the ion moving from the gate minimum, leaving it available for anion from bulk, so the cycle continues. the arrange- ment of water, and the ion hydration, defines the gate energy minimum, and this in turn depends on the highly conserved prolines, especially p ( a pdb numbering), in the pvpv sequence in the gate. absent an energy minimum at the gate an ion entering from solution would be repelled back into solution by the ion in the cavity. furthermore, the ion remains hydrated by water molecules, at least more than in bulk, as it passes through the gate, based on optimizations with the ion at three different positions: ) at the gate position nearest p ) å above ) å below, this position. the open gate maintains very nearly the same protein atom positions throughout. additional calculations will be required to determine the exact interaction en- ergy with an ion in the cavity, and the amount of water that is present in the cavity. optimizations of the system configuration were done at hf/ - gsp level, with atoms ( with the ion). energy was determined using both b lyp/ - g* and bvp / - g*, but the system was too large for free en- ergy determination. -pos board b water structure at the potassium channel gate: the importance of the prolines in the pvpv sequence, as shown by computational mutations, and the role of a histidine in gating alisher m. kariev, michael e. green. city college of the city university of ny, new york, ny, usa. conservation of the pvpv sequence at the potassium channel gate has not been well understood. quantum computations (optimization at hf/ - gsp level) of the gate of the kv . channel that are presented here show that the proline-proline distances (ring atoms) are preserved as the ion moves through the gate. this calculation is supplemented by mutating one of the prolines to valine (p v, a pdb numbering for all residues in this abstract) in the computation, producing a pvvv sequence. water structure changed dramati- cally, as the protein backbone moved inward nearly å, effectively closing the channel; the proline ring n-n distance between diagonally opposite pro- lines dropped from . å (distance from optimization: x-ray distance = . å) to . å, too small to allow passage of a hydrated k þ . this suggests that the prolines play a key structural role, modulating both protein and water structure. furthermore, protonation of h may close the channel. protonation of this histidine shows it moving toward the gate by about å, which should close the gate electrostatically, while deprotonation opens the gate. protonation was calculated with two added protons, the other being accepted by e of the t intracellular moiety. when deprotonated, the histidine does not move as much as å from the x-ray position in the optimization, and is linked to e ; this accounts for the known importance of the t segment in gating. e , also of t , could accept a third proton. there is a salt bridge structure including these residues similar to the one occupying a key position in the pro- ton pathway in the hv channel. access constraints and binding energetics of a potassium channel inactivation gate

and chemokine receptor-binding sites. additionally, by incorporating t - and -helix- resistance mutations into individual env protomers, we were able to interrogate exposure of discrete gp n-hr and c-hr domains. our data indicate that a single cd binding to an env trimer is sufficient to promote fusion. moreover, the first cd binding event appeared to expose only one of three possible binding sites for each fusion inhibitor, suggesting an asymmetric transition into the phi. this asymmetry was significantly more pronounced in the gp n-hr region compared to the gp c-hr region. these results can be used to explain the multiphasic titration of mutant env homotrimers that naturally form asymmetric n-hr domain structures. taken together, these data suggest that the native state-to-phi transition of env occurs in a multistep (asymmetric) fashion. -pos board b evolution of hiv- resistance to a cholesterol-linked d-peptide fusion inhibitor amanda e. siglin , nicholas francis , michael s. kay , micheal j. root . thomas jefferson university, philadelphia, pa, usa, university of utah, salt lake city, ut, usa. during hiv- entry, the n-hr and c-hr regions of the gp viral glycoprotein associate to form a trimer-of-hairpins critical for membrane fusion. the n-hr region contains a highly conserved hydrophobic pocket that is the target for a multivalent, d-peptide fusion inhibitor, pie -trimer. recently, a modified form of this inhibitor with a conjugated cholesterol (chol-pie -trimer) was shown to possess up to -fold increased potency, presumably due to mem- brane targeting. here, we determined the resistance profile of chol-pie - trimer starting from either inhibitor-naı̈ve or pie -trimer-resistant hiv- (nl - strain). viral propagation in increasing inhibitor concentrations pro- duced hiv- populations with - to -fold reduced sensitivity chol- pie -trimer. these viruses were also resistant to the parental, unconjugated inhibitor pie -trimer. using hiv- fusion inhibitors di-c and -helix, we were able to interrogate the effect of escape mutations on the exposure of the gp n-hr and c-hr regions, respectively. resistance to chol-pie - trimer resulted in a slight decrease in the temporal window of n-hr exposure, regardless of the starting viral population. exposure of the c-hr region was unchanged for resistant viruses generated from the inhibitor-naı̈ve viral pool. by contrast, the temporal window of c-hr exposure was significantly increased (> -fold) for resistant viruses that were generated from the pie -trimer-resistant viral pool. efforts to identify the mechanisms of chol- pie -trimer resistance and the decoupling of n-hr and c-hr exposure are underway. -pos board b fusogenic activity of the hiv- gp mper-tmd region: mechanism and targeting by immunogens and inhibitors jose l. nieva , beatriz apellaniz , carmen domene , nerea huarte , eneko largo . biophysics unit (csic-upv/ehu) and dept. of biochemistry, university of the basque country (upv/ehu), bilbao, spain, chemistry research laboratory, university of oxford, oxford, united kingdom. fusion of the viral envelope with the cell membrane marks the beginning of the hiv- replicative cycle. this event is targeted by inhibitors currently in clinical use and by preventive vaccines under development. antibodies e and e bind to the gp membrane proximal external region (mper)- transmembrane domain (tmd) junction and block fusion. these antibodies display the broadest viral neutralization known to date, which underscores the conservation and functionality of the mper-tmd region. in recent work, we have described that peptides representing this region have potent membrane-destabilizing effects. here, based on the outcome of vesicle assays, atomic force microscopy studies and molecular dynamics simulations, we propose a mechanism for the involvement of the mper-tmd region in hiv- fusion. in addition, we provide evidence that underpins the poten- tial use of its activity as a new target for inhibitor and immunogen development. -pos board b studies on the membrane-active behavior of outer membrane vesicles from a gram negative bacterium william bartos, rensa chen, donald y. kobayashi, paul r. meers. rutgers, the state university of new jersey, new brunswick, nj, usa. gram-negative bacteria are known to produce small ~ - nm vesicles by ‘‘blebbing’’ of their outer membranes. these outer membrane vesicles (omv) have been implicated in activities such as transmission of virulence fac- tors, horizontal gene transfer and development of biofilms. in this investigation, the interactions of omv from lysobacter enzymogenes (strain c ) with other membranes have been monitored using fluorescent assays for association and/or fusion. defined composition large unilamellar vesicles labeled with the fluorescence resonance energy transfer (fret) pair , -dipalmitoyl-sn- glycero- -phosphoethanolamine-n-( -nitro- - , -benzoxadiazol- -yl) (nbd- pe) and , -dipalmitoyl-sn-glycero- -phosphoethanolamine-n-(lissamine rho- damine b sulfonyl) (rh-pe) were incubated with isolated omv to observe the interaction via the fret ratio of donor/acceptor. omv substantially increased this ratio over the course of about an hour (t / ~ - min.) at �c, when added directly to vesicles comprising disordered or fluid lipids, such as -palmitoyl- -oleoyl-sn-glycero- -phospho-( ’-rac-glycerol) (popg), -pal- mitoyl- -oleoyl-sn-glycero- -phosphoethanolamine (pope) or -palmitoyl- - oleoyl-sn-glycero- -phosphocholine (popc). this apparent fusion was much more limited or absent with liquid ordered membranes of , -dipalmitoyl-sn- glycero- -phosphocholine/cholesterol (dppc/chol). in the case of popg/ pope / vesicles, apparent fusion was also confirmed by testing vesicles with exclusively inner monolayer fluorescent probes to diminish any fluores- cence changes from external interactions of outer monolayer fluorophores. when the omv were labeled with the fluorophore , -dioctadecyl- , , , - tetramethylindocarbocyanine, and incubated with a natural host, yeast cells (strain s ), association and/or fusion was observed by co-sedimentation of the omv label with yeast cells. these studies may help to elucidate the mech- anism of natural host-pathogen interactions and define the lipid specificity for hiv fusion peptide perturbs membrane structure in a cholesterol dependent fashion cd binding induces an asymmetric transition of hiv- env from its native conformation into the prehairpin intermediate state evolution of hiv- resistance to a cholesterol-linked d-peptide fusion inhibitor fusogenic activity of the hiv- gp mper-tmd region: mechanism and targeting by immunogens and inhibitors studies on the membrane-active behavior of outer membrane vesicles from a gram negative bacterium case report a -year-old male with fever and persistent lung infiltrate tajender s vasu md, rodrigo cavallazzi md, amyn hirani md, and paul e marik md acute fibrinous and organizing pneumonia is a newly recognized pattern of lung injury. it may be idiopathic or secondary to a variety of lung injuries. in this case report we describe a -year-old male with acute fibrinous and organizing pneumonia caused by decitabine. he had substantial clinical and radiological improvement after the discontinuation of decitabine and a course of corticosteroids. key words: acute respiratory distress syndrome, ards, acute lung injury, ali, decit- abine, myelodysplastic syndrome, drug induced pneumonitis, acute fibrinous and organizing pneumonia. [respir care ; ( ): – . © daedalus enterprises] introduction a wide variety of drugs can cause pulmonary injury and should be considered during the evaluation of lung infil- trate. early diagnosis is important because unrecognized toxicity can be progressive and even fatal. drug-induced lung injury may manifest in a variety of histological pat- terns. acute fibrinous and organizing pneumonia is a dis- tinct pattern of reaction of the lung to injury. it is char- acterized by intra-alveolar fibrin balls and organizing pneumonia. the absence of hyaline membranes, granulo- matous inflammation, and eosinophilic deposition are im- portant distinguishing features. case report a -year-old male came to our hospital with dry cough, fever, and chills, of weeks duration. he had a history of myelodysplastic syndrome, developing after the successful treatment of acute myelogenous leukemia. four weeks earlier he had received mg of intravenous decitabine daily for days. at the time of hospitalization he had just completed a second course of decitabine. on examination his temperature was °f, blood pressure was / mm hg, heart rate was beats/min, oxygen saturation was % on room air, and respiratory rate was breaths/ min. his lung examination had inspiratory crackles in the left lung base. the rest of his physical examination was unremarkable. he had pancytopenia, with white-blood-cell count of . � cells/l (normal range of – � cells/ l), hemoglobin of . g/dl (normal range of – g/dl), and platelets of , cells/l (normal range of , – , cells/l). his differential count showed % neu- trophils, % lymphocytes, and % monocytes. his se- rum sodium, potassium, creatinine, magnesium, calcium, and liver function test were all within normal limits. blood and urine cultures were negative. the chest radiograph showed an ill-defined left-lower-lobe infiltrate. he was started on broad-spectrum antibiotics, including an anti-fungal agent. the computed tomography scan of his chest (fig. ) revealed a left-lower-lobe consolidation. computed-tomography-guided needle aspiration of the left lower lobe was non-diagnostic. he underwent bronchos- copy with bronchoalveolar lavage, which was non-diag- nostic. his bronchoalveolar lavage fluid showed % mac- rophages, % neutrophils, and % lymphocytes. he remained febrile despite treatment with antibiotics. a re- peat computed tomography of the chest (fig. ) days later showed worsening of the left-lower-lobe consolida- tion. the patient underwent video-assisted thoracoscopic wedge biopsy of the left lower lobe. the open-lung biopsy from the left-lower lobe (fig. ) showed patchy areas of organizing pneumonia with fibrin balls within the alveoli and air spaces. there was no hyaline membrane. the di- agnosis of

started on methylprednisone mg intravenously, every hours, fol- lowed by mg of oral prednisone daily. he had substan- tial clinical and radiological improvement after discontin- uation of decitabine and a course of corticosteroids. discussion acute fibrinous and organizing pneumonia was first de- scribed by beasley et al in . in their paper they noted several conditions associated with acute fibrinous and or- ganizing pneumonia, including collagen-vascular disease, lymphoma, amiodarone, and infections caused by hae- mophilus influenzae and acinetobacter baumannii. re- cently, acute fibrinous and organizing pneumonia has also been reported in patients with dermatomyositis, acute lym- phocytic leukemia, severe acute respiratory syndrome, and secondary to drugs, including abacavir and busulfan. patients with acute fibrinous and organizing pneumonia may have an acute or subacute clinical course. the pattern of the acute form resembles the clinical picture of acute lung injury. decitabine is a hypomethylating agent that was recently approved by the food and drug administra- tion for the treatment of myelodysplastic syndrome. the major adverse effect of decitabine is myelosuppression. other adverse effects, including fever, nausea, vomiting, diarrhea, bone aches, hyperbilirubinemia, and skin rash, have also been described. to the best of our knowledge this is the first case describing acute fibrinous and orga- nizing pneumonia pattern of lung injury secondary to de- citabine. the classic histological findings of acute fibrinous and organizing pneumonia include intra-alveolar fibrin balls with organizing pneumonia. this pattern must be distin- guished from diffuse alveolar damage, bronchiolitis oblit- erans organizing pneumonia, and eosinophilic pneumo- nia. fibrin deposits are found in diffuse alveolar damage and bronchiolitis obliterans organizing pneumonia, but, fig. . computed tomogram shows a left-lower-lobe consolida- tion. fig. . repeat computed tomography days later shows wors- ening of the left-lower-lobe consolidation. fig. . micrograph from the open-lung biopsy of the left-lower lobe shows patchy areas of organizing pneumonia with fibrin balls in the alveoli and air spaces. a -year-old male with fever and persistent lung infiltrate respiratory care • september vol no unlike acute fibrinous and organizing pneumonia, these deposits do not represent the major findings. the air-space involvement in acute fibrinous and organizing pneumonia is patchy in distribution, as opposed to diffuse involve- ment in diffuse alveolar damage. hyaline membranes, gran- ulomatous inflammation, and eosinophilic infiltrates are absent in acute fibrinous and organizing pneumonia. the retrospective review by beasley et al demonstrated that approximately % of patients with acute fibrinous and organizing pneumonia required mechanical ventila- tion. notably, all those patients who needed mechanical ventilation died. the acute fibrinous and organizing pneu- monia pattern portends a poor prognosis, with a mortality rate of more than %. the clinical course of these pa- tients is similar to those with diffuse alveolar damage, and, indeed, acute fibrinous and organizing pneumonia may be a fibrinous variant of diffuse alveolar damage. treatment with corticosteroids and discontinuation of the underlying drug may be attempted. references .

uppsala, sweden, nicox, sophia antipolis cedex, france, nicox, sophia antipolis, france, european health economics, speracedes, france objectives: to estimate changes in quality of life (sf ) and utility (sf ) in patients treated with naproxcinod, naproxen or placebo for weeks, and to explore the effect of different disease measures on utility. methods: sf was available from international ph clinical trials in patients with knee or hip osteoarthritis comparing doses of naproxcinod ( and mg bid) to naproxen ( mg bid) and placebo. effi cacy was based on the pain, function and composite scales of the womac™ osteoarthritis index. co-morbidity measures included hypertension (ht) which increases with nsaid therapy, body mass index (bmi) and diabetes. changes in sf and individual sf domains were compared between the groups using anova and dunett’s -sided test. the effect of the womac™ indices, bp, bmi and diabetes on utility scores was explored using multiple regression analysis. results: all sf subscales except mental health as well as utility changed signifi cantly from baseline for all groups, and were correlated with changes in the womac™ indices (p . ). the change in the active groups was signifi cantly better than placebo for pain and physical function ( . ), but not signifi cantly different between treatments. however, absolute changes in utility, pain, physical function and general health were generally larger for naproxcinod mg than naproxen mg by around %. utility scores correlated signifi cantly with womac™, and patients with high bmi and bp or diabetes had lower utility scores and worse womac™ indices. increase in utilities were larger for patients with mg naproxcinod than for the other groups. conclusions: the slightly larger utility and quality of life changes with naprox- cinod mg despite a similar effect as naproxen on womac™ may be explained by a different side-effect profi le and a neutral blood pressure effect. pms an assessment of self reported outcomes in a nationally representative sample of elderly person diagnosed with rheumatoid arthritis rajpura jrjp j st. john’s university, fresh meadows, ny, usa objectives: to utilize webtv technology as a tool to measure hrqol in elderly persons having rheumatoid arthritis (ra) in a nationally representative sample and to describe their socio-demographic characteristics, medication use and other treat- ment choices. methods: a cross- sectional online survey research design. random digit dialing (rdd) survey procedures were used to draw a sample of elderly arthritic individuals from us households across states. a subsample of individu- als previously diagnosed with ra completed sf- v survey, as part of a larger study. eight sf- domain scores and physical and mental component summary (pcs and mcs) scores were computed and compared with cross-sectional norms for general us population. results: compared to the general population, our study sample per- formed poorly with respect to all the sf- domains except mental health (mh) and social functioning (sf) domains. ra is more prevalent in whites ( %) and males reported higher scores for all the eight sf- domains than females. about % of the sample reported the use of at least one available otc arthritic medication; % of the sample was taking prescription drugs, while about % reported having used natural/herbal remedies for arthritis. a signifi cant difference (p . ) was found between males and females with respect to only pcs scores. age was found to correlate negatively (p . ) with pcs and mcs summary measures, particularly for indi- viduals years and older. conclusions: webtv is an effective survey administra- tion tool for measuring hrqol. as expected, elderly perform poorly on three of the sf- domains (pf, rp, bp) having the most physical factor content. prescription drug use is fairly prevalent and use of otc medications and other forms of treatment is popular in the population under study. pms the effect of lifestyle choices on the risk of impairment in rheumatoid arthritis patients: an analysis of aerobic exercise and cigarette smoking shah a , plumb j , brawer r , tang b thomas jefferson university, philadelphia, pa, usa, centocor ortho biotech, inc, horsham, pa, usa objectives: through data analysis we will examine and identify the lifestyle factors that impact clinical outcomes of rheumatoid arthritis (ra) patients. methods: patients’ self-reported data was collected from the ra patient survey, an internet survey of ra patients. we studied the effects of aerobic exercise ( minutes a day per month), and cigarette smoking on ra patients. sign and symptom scores for morning stiffness, fatigue, and pain are defi ned from (no symptom) to (severe symptom) within the survey. the health assessment questionnaire (haq) was used to measure functional status scores ( – ). quality of life was measured by the mental component score (mcs) and physical component score (pcs) of the short-form (sf- ). productivity was measured by the work productivity and activity impairment (wpai) scale. there were no non-ra controls included in the study. results: a total of respondents were included in the analysis patients exercised and patients smoked cigarettes. the average age was . years and average ra duration was . years. patients’ mean mcs and pcs scores in the exercise ( . , . ) and non-smoking groups ( . , . ) were signifi cantly higher, than in the non- exercise ( . , . ) and smoking groups ( . , . ). overall work and productivity impairment was . % (exercise) versus . % (non-exercise), and . % (smoking) versus . % (non-smoking). signs, symptoms, and haq scores were signifi cantly better in the exercise and non-smoking groups (all p . ). conclusions: ra patients who exercise regularly have higher quality of life scores and clinical outcomes. those that smoke cigarettes have lower quality of life scores and higher symptom/ haq scores suggesting that this habit may be detrimental to their clinical outcomes. these results suggest that these lifestyle choices infl uence the overall risk of impairment in ra patients. pms is the health

netherlands objectives: qalys are an important outcome used in cost-effectiveness analysis. the health utilities index mark (hui- ) is a self-reported measure covering attri- butes of health status. our objective was to assess construct validity and responsiveness of hui- in ankylosing spondylitis (as). methods: data were derived from the adalimumab trial evaluating long-term effi cacy and safety in as (atlas). we speci- fi ed a priori hypotheses regarding the direction and magnitude of associations expected between overall and single-attribute hui- scores and other health status and quality of life measures—sf- , asqol, bath as functional index (basfi), bath as disease activity index (basdai), and patient’s global assessment (pga). using baseline data, we calculated correlation coeffi cients and interpreted them via guidelines suggested by guyatt for negligible, weak, moderate, and strong associations. responsiveness was assessed by calculating standardized response means (srms) of hui- scores from baseline to week for patients meeting the minimum clinically important differences (mcid) for the asqol ( . ). responsiveness analysis was limited to patients with -week hui- scores. results: a total of of the patients enrolled in atlas were included in the analysis. mean age was years, . % were male, and mean duration of as was years. correlation coeffi cients between hui- scores and other instruments confi rmed . % of the a priori hypothesis, with an additional . % being under- or over-estimated by only one category. results of responsiveness analysis demonstrated that there were signifi cant differences in overall hui- (srm . ) and most single-attribute change scores for patients whose changes were greater than the asqol mcid vs. those whose changes were mcid. conclusions: these results suggest that hui- constructs are related to similar constructs in other measures, as expected. this study provides evidence of cross-sectional and longitudinal construct validity of the hui- for deriving utility scores for as patients. pms validation of the multi-attribute health utility (mahu) derived from a computer adaptive instrument, cat- d-qol, in osteoarthritis

structure infections due to staphylococcus aureus: findings from a national database a abstracts analyses were conducted from both the societal and health care system perspective. sensitivity analyses were performed. results: reduction in disease outcomes, disease sequelae and cost-of-illness by health state was observed in the time period post-prevnar®, across all age groups. the total cost of the vac- cination program to the canadian health care system (including herd immunity effects), from a payer perspective amounted to $ , , ; this decreased to $ , , from a societal per- spective. the total number of illnesses avoided was , . the incremental cost-effectiveness ratio (icer) was $ , and $ , per additional qaly from the health system and soci- etal perspectives, respectively. when herd immunity effects were excluded from the analysis, the icer increased to $ , and $ , per qaly, respectively. sensitivity analysis indicated that total cost and icer results were most sensitive to changes in the epidemiology and cost of otitis media. however, these changes did not considerably impact the results, indicating a robust model. conclusion: consistent with previous find- ings, vaccination with prevnar® is cost-effective. administration of prevnar® results in a substantial reduction in pneumococcal disease in vaccinated children and unvaccinated adults. pin

shinjyuku-ku, tokyo, japan, kyoto university, kyoto, kyoto, japan, osaka saiseikai senri hospital, suita, osaka, japan objectives: to investigate the cost effectiveness of gargling to prevent upper respiratory tract infections (uri) from a societal perspective. methods: the effectiveness of gargling for pre- venting uri has been demonstrated in a randomized controlled trial in which the participants recorded the frequency of gargling, incidence and severity of uri and duration of daily medicine. costs of gargling, visiting physicians, medicine, and lost pro- ductivity were considered. the cost of gargling was estimated as the opportunity cost of the time required. the utility of severe and moderate uri was also considered. average costs and utility during days of observation in the trial were estimated as the sum of the average daily cost and utility of the participants remaining staying in the trial. the incremental cost effectiveness ratio (icer) of gargling when compared with the absence of gar- gling was calculated, and bootstrap sampling generated an acceptability curve. results: the estimated unit cost of gar- gling was . yen. assigned participants gargled . times per day on average. the gargling group had higher costs and utility than the group that did not gargle. the incremental cost and effectiveness for days were yen and . quality- adjusted

acceptability curve showed . % was less than million yen/qalys, and . % less than million yen/qalys. conclusion: although it can prevent uri, gargling is more costly than not gargling because the cost

community- acquired pneumonia treatment kulikov a, krysanov i moscow medical academy, moscow, russia objectives: selection of the most cost-effective treatment regimen of severe community-acquired pneumonia. methods: direct medical expenditure on courses of treatment with lev- ofloxacin and ceftriaxone were evaluated during this trial. “cost minimization” analysis was chosen as a pharmacoeconomic method, and a “lost opportunities” index was calculated when using less cost-effective drugs. results: direct medical costs in the group of patients who received levofloxacin amounted to , . rubles, and in the group of patients who were treated with ceftriaxone they totaled , . rubles per patient. they were made up of levofloxacin and ceftriaxone antibacterial drug treatment costs and the costs of patients’ hospital stay. the cost of the drug treatment course amounted to , . rubles for the first group (levofloxacin) and to , . rubles for the second group (ceftriaxone); the cost of hospital stay amounted to , rubles and , rubles respectively. in the break- down of expenditure on treatment of community-acquired pneu- monia with levofloxacin, patients’ hospital stay accounted for % of expenses, whereas drug treatment accounted for only % thereof; when treating with ceftriaxone, the expenditure on patients’ hospital stay amounted to % and that on drug treat- ment—to %. the “lost opportunities” index equaled one and thus indicated that when using a more cost-effective drug (lev- ofloxacin) for the treatment of one patient compared to a less cost-effective drug (ceftriaxone) it is possible to theoretically treat an additional patient, taking into account the difference in the costs of treatment with the drugs compared, provided the profile of antibiotic resistance is congruent with that under the conditions of the clinical study used herein. conclusion: antibacterial treatment of severe community-acquired pneumo- nia with levofloxacin is more cost-effective, enabling the reduc- tion of costs by , rubles per patient compared to treatment with ceftriaxone owing to lower expenditure on drugs. pin the clinical and economic burden of complicated skin and skin structure infections due to staphylococcus aureus: findings from a national database marton jp , menzin j , sussman m , friedman m , philburn rt , rothermel cd pfizer global pharmaceuticals, pfizer inc, new york, ny, usa, boston health economics, inc, waltham, ma, usa objectives: complicated skin and skin structure infections (csssis) are a common complication among hospitalized patients. there are limited national data on the costs of csssis due to staphylococcus aureus, a common hospital-acquired pathogen. methods: this retrospective cohort study used data from the health care cost and utilization project nationwide inpa- tient sample (hcup-nis). patients with s. aureus csssis were identified based on icd- -cm diagnosis codes and compared to patients without skin infections. excess mortality, length of stay (los), and costs were estimated for both groups. multivariate models (with log transformation) were used to adjust costs for potential confounding factors, including age, gender, mortality, hospital region, and comorbidity. results: we identified , hospitalized patients with csssis due to s. aureus. the compari- son cohort consisted of , , patients without skin infec- tions. the mortality rates were similar for the s. aureus csssi and comparison cohorts ( . % and . %, respectively). for com- a abstracts parison purposes, the mortality rate of all inpatients with s. aureus infections was . %. patients with s. aureus csssis were older (mean age years vs. years for the comparison group) and were more likely to have congestive heart failure, diabetes with chronic complications and bacteremia/septicemia. relative to the comparison group, patients with s. aureus csssis had significantly (p < . ) longer mean length of stay ( . vs. . days) and higher average costs per stay ($ , vs. $ , ). after con- trolling for potentially confounding factors, the excess mean costs associated with s. aureus csssis were estimated to be $ , . conclusion: our findings suggest that the clinical and eco- nomic burden of complicated skin and skin structure infections (csssis) due to staphylococcus aureus among hospitalized patients is substantial. pin impact of s. aureus infections on expenditures and length-of-stay in u.s. hospitals noskin g , rubin r , schentag j , kluytmans j , hedblom e , jacobson c , smulders m , gemmen ek ,

evaluate the incremental impact of s. aureus infection stays on hospital charges and length-of-stay in u.s. hospitals in . methods: the nationwide inpatient sample data were analyzed. hospital discharges were classified as either a s. aureus–related infection stay or a non-s. aureus- related infection stay using a combination of several icd- codes. incremental effect of s. aureus infection on hospital charges and length-of-stay was estimated using multivariate regression models adjusting for hospital fixed effects and patient variables including age, gender, race, payer, diagnosis-related grouping and concomitant conditions including diabetes, dialy- sis and lung disease. results: s. aureus infection was reported as a discharge diagnosis for . % of all hospital inpatients, or , stays, in . s. aureus infection hospital stays were significantly more likely among male, older patients, stays that were paid by medicare, white or non-hispanics and hospital stays among individuals with diabetes, lung disease or dialysis. after adjusting for covariates, the mean incremental impact of s. aureus infection on hospital charges and length-of-stay was $ , ( %

economic impact of s. aureus among all hospital admissions was estimated at $ . billion in u.s. dollars. pin determinants of total hospital costs among inpatients with candidemia lee sp , bunz t , gagne jj , maio v , goldfarb ni , horn dl , swanson r thomas jefferson univeristy, philadelphia, pa, usa, thomas jefferson university, philadelphia, pa, usa, pfizer inc, new york, ny, usa objectives: to identify factors associated with total hospital costs among patients with candidemia in a large, urban, tertiary care, teaching hospital. methods: this retrospective cohort study examined hospitalizations during calendar years and at thomas jefferson university hospital in philadelphia, pa, using data from various hospital systems. candidemia cases were identified via the microbiological laboratory information system as those patients with at least one confirmed positive blood culture for any candida species at any point during the study period. demographic, economic, and clinical data, includ- ing length-of-stay (los), payer types, total costs, and diagnosis related group (drg) assignments were collected from the hos- pital cost accounting system. pharmacy data (i.e. medications administered and associated costs) were retrieved from the phar- macy electronic information system. a multivariate regression analysis, using the natural logarithm of total hospitalization costs as the dependent variable, was conducted. independent variables included demographic information, relative drg weights, and candida species. results: among , total hospitalizations during the study period, cases were con- firmed positive for candidemia. the mean age of cases was years, % were female, and % were caucasian. the mean los was . days and the average inpatient cost for candidemia cases was $ , (sd = $ , ; median, $ , ). the most common candida species was c. albicans (n = ; %). the most commonly used antifungal treatment was fluconazole (n = , %). age, and relative drg weights (p < . ) were significantly positively correlated with total hospital costs. older patients with higher relative drg weights were associated with the higher total costs. race, gender, and marital status were not associated with total costs. conclusion: relative drg weights, as well as age are associated with total hospital costs among patients with candidemia. candidemia is expensive to treat and results in lengthy hospital stay. early detection and treatment may significantly reduce resource use as well as improve outcomes. pin the economic impact of

mitochondrial motility by milton-like proteins, oip and grif sudipto das, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. regulation of mitochondrial motility by milton-like proteins, oip and grif grif and oip are mammalian homologs of milton, a kinesin-binding protein that forms a complex with miro gtpase, an integral outer mitochon- drial membrane ef-hand protein. kinesin, milton and miro have been proposed to function together in the movement of mitochondria along the mi- crotubules. we report here the influence of overexpression of oip and grif on mitochondrial motility and its inhibition by agonist-induced cyto- plasmic [ca þ] ([ca þ]c) signals in h c cells. ha-tagged oip and grif were overexpressed at similar level and were localized to the mito- chondria as detected by immunocytochemistry. in oip and grif overex- pressing cells, elongated mitochondria with varied degree of aggregation were visualized both in live and in fixed, immunostained samples. mitochondrial motility at resting ca þ (< nm) was greatly enhanced by oip and to a lesser extent by grif ( . . and . motility units, respec- tively against a control value of . . motility units). furthermore, the ca þ-dependent inhibition of motility during stimulation by vasopressin ( nm) was suppressed by overexpressed oip ( . . %), whereas grif ( . . %) had no significant effect compared to control ( . . %). overexpression of oip or grif did not alter either basal [ca þ]c or agonist-induced [ca þ]c levels measured by fura . collectively, these data show that both oip and grif can modulate mitochondrial motility presumably, by promoting the association of mitochondria with the motor proteins. furthermore, oip seems to have greater efficacy in the control of mitochondrial movements. -pos board b mitochondrial localization and function relationship gyorgy csordas , sudipto das , peter varnai , tamas balla , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, school of medicine, budapest, hungary, nichd, nih, bethesda, md, usa. mitochondrial contribution to cell signaling and function relies on the associ- ation and local communication of mitochondria with the er and the plasma membrane (pm). we have recently shown that the local ca þ communication between er and mitochondria is supported by interorganellar tethers, and cre- ated synthetic linkers that connected the outer mitochondrial membrane (omm) to the er and sensitized mitochondria to er ca þ release. to study the kinetics and short-term effects of the linkage formation, we have now de- vised fluorescent protein pairs targeted to the omm and er or pm containing fkbp or frb domains. rapamycin causes heterodimerization of these pro- teins to form omm-er or omm-pm bridges. confocal imaging of the induc- ible fluorescent linker pairs revealed increased association of er or pm-patches with the mitochondria within minutes of rapamycin exposure. the linkage formation between the er and mitochondria was followed by a decrease in mi- tochondrial motility (> % in min) and by sensitization of mitochondria to ip receptor-mediated ca þ release. linkage formation between pm and mitochondria also suppressed mitochondrial motility. the initial kinetics and spatial distribution of linkage formation could be followed via recording fret between cfp-and yfp-containing linker partners. a longer version of the linker was found to show faster increase of the fret signal, supporting the idea that the rate of linkage formation positively correlates with the tight- ness of the er-mitochondrial contacts. currently, we are using the fret kinet- ics to visualize the areas of close er-mitochondrial interface and study its relevance in the ca þ signal propagation to the mitochondria. thus, inducible interorganellar linkers provide a tool to assess the distance between organelles in live cells, to establish rapid changes in the subcellular distribution and dynamics of the organelles and to evaluate the ensuing changes in organellar and cell function. -pos board b bak/bax-dependent apoptotic signaling in vdac -/- cells soumya sinha roy , william j. craigen , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, baylor college of medicine, houston, tx, usa. bid, a pro-apoptotic bcl- family protein, upon activation forms truncated bid (tbid) that binds to the outer mitochondrial membrane (omm) and engages bak/bax-dependent release of cytochrome c (cyto c) and other intermembrane space proteins from mitochondria to the cytosol to induce apoptosis. the volt- age-dependent anion channel (vdac) is the major permeability pathway for metabolites and ions in the omm but its role in the tbid-induced omm perme- abilization remains controversial. previously we reported that among the vdac isoform-specific knockout mouse embryonic fibroblasts (mefs), only vdac -/- mefs lack tbid induced complete cyto c release and loss of djm. here we show by single cell fluorescence imaging that permeabilized vdac -/- mefs expressing cyto c-gfp were resistant to tbid ( nm)-induced cyto c-gfp release. furthermore, by rescuing vdac -/- mefs with vdac the tbid-induced cyto c-gfp release was restored. in addition, tbid adenovirus infection caused less cell death in intact vdac -/- mefs than in wildtype (wt) mefs. it has been reported that vdac is required for proper targeting of bak in omm. indeed, bak did not appear in the membrane fraction of vdac -/- mefs. along this line we show that permeabilized bak -/- cells were more resistant to tbid induced cyto c release and loss of djm than wt and bax-/- mefs. strikingly, washout of the cytosol further desensitized the bak-/- mefs to tbid. unlike vdac -/- mefs, the bak-/- mefs constitutively overex- pressed bax that was primarily localized in the cytosol. however, recombinant bax ( nm) could induce cyto c release and depolarization in vdac -/- mefs and also supported the tbid-induced cyto c release. thus, in vdac -/- cells bak does not localize to the mitochondria and fails to interact with tbid and does not allow a compensatory increase in bax. the combination of these two mechanisms greatly attenuates tbid-induced omm permeabilization and apoptosis. -pos board b mitochondrial fusion-fission dynamics during hypoxia/reoxygenation xingguo liu, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. structural, biochemical, and functional abnormalities of mitochondria during hypoxia/reoxygenation (h/r) are widely believed to be important pathogenic factors that underlie cell injury. however, mitochondrial fusion-fission dynam- ics responses to h/r are unclear. we investigated the effect of h/r and chem- ical hypoxia evoked by kcn on cellular atp, djm, and on mitochondrial morphology and fusion. sixty min h caused cellular atp decrease to %. djm showed progressive decrease during h, gradually improved in the first minutes r and decreased again during longer r. mitochondrial fusion activity decreased to % during h and to % during r. in addition, anomalous fusion (autofusion and fusion at multiple sites among - mitochon- dria) produced donut-shaped mitochondria during r. cyclosporine a (csa), an inhibitor of the permeability transition pore (ptp) relieved the fusion inhibition ( %) and prevented donut formation during r. five mm and mm kcn could induce cellular atp decrease to % and %, and djm decrease to % and %, respectively. depolarized mitochondria were associated with donut-formation in mm kcn, and with massive swell- ing in mm kcn. fusion activity decreased to % in mm kcn and % in mm kcn, respectively. neither h nor kcn evoked cleavage of opa , the mitochondrial inner membrane fusion protein. thus, both physical and chem- ical h induced respiratory inhibition to gradually lower djm and cellular atp level, and caused fusion inhibition that was not dependent on opa cleav- age. this is sharp contrast of the uncoupler-induced fusion inhibition that has been attributed to the rapid djm dissipation-induced opa cleavage. a conse- quence of ptp opening, the matrix swelling seems to be a key to donut forma- tion since this could be evoked by both mastoparan, a potent ptp activator and by valinomycin, a potassium ionophore. -pos board b governing respiration: tubulin’s c-terminus interaction with vdac kely l. sheldon , dan l. sackett , claire monge , valdur saks , sergey m. bezrukov , tatiana k.

mitochondria have long been known to localize within and move along the tu- bulin-microtubule network. it was shown that tubulin binds to isolated mito- chondria with high-affinity and specifically associates with the mitochondrial voltage-dependent anion channel (vdac). we found that nanomolar concen- trations of dimeric tubulin vastly increase vdac sensitivity to voltage allow- ing for vdac blockage at low transmembrane potentials. tubulin interaction with vdac requires the presence of anionic c-terminal tails (ctt) on the in- tact protein. tubulin with proteolytically cleaved ctts does not block the channel. actin, also an acidic protein but lacking ctts, does not induce vdac blockage. two synthetic peptides with the sequences of mammalian a and b brain tubulin ctt do not induce detectable channel closure up to mi- cromolar concentrations. these results suggest a completely new role for regulation of mitochondrial motility by milton-like proteins, oip and grif mitochondrial

new exotic baryon with strangeness quantum number s �� and valence quark structure udud�s. the renewed interest in pentaquarks was motivated by a prediction within the chiral soliton model [ ] for a s �� baryon at a mass of mev and width of less than mev. if it exists, this would be the first observation of a baryon state that is not made up of a simple -quark (qqq) valence configuration. the observation of a second pentaquark, the ��� with dsds �u structure, was reported by the na collaboration [ ] and the first evidence for an anticharmed pentaquark, �c, was found by the h collaboration [ ]. on the other hand, in the past year reanalyses of data collected in high-energy experiments [ – ] show no evidence for pentaquarks, casting doubt on their existence. the experimental evidence, both positive and negative, was obtained from data previously collected for other purposes in many reaction channels and under very differ- ent kinematic conditions, which likely involved dissimilar production mechanisms. thus, direct comparisons of the results of the different experiments are very difficult, pre- venting a definitive conclusion about the pentaquark’s ex- istence. a second generation of dedicated experiments, optimized for pentaquark searches, was undertaken at the thomas jefferson national accelerator facility. these photo-production experiments cover the few gev beam energy region where most of the positive results have been reported, and collect at least an order of magnitude more statistics than any of the previous measurements. the mass resolution is of the order few mev and the accuracy of the mass determination is approximately – mev, allowing precise determination of any possible narrow peaks in the decay distributions. this letter presents the first result from this program. we searched for the �� in the �p ! �k k�n reaction, where the k�n decay mode identifies a baryon with strangeness � . this channel was previously investigated at elsa by the saphir collaboration [ ] in a similar photon energy range, finding positive evidence for a narrow �� state with m � mev and full width at half maximum (fwhm) � < mev. a total production cross section on the order of nb (reduced later to nb as reported in ref. [ ]) was reported. for the first time, our new results put previous positive findings to a direct test. this measurement was performed using the clas [ ] detector at jefferson lab in the experimental hall-b with a bremsstrahlung photon beam produced by a primary continuous electron beam of energy e � : gev. a bremsstrahlung tagging system [ ], which measures the energy of each interacting photon with resolution of . % e , was used to tag photons in the energy range . – . gev. the target consisted of a cm long cylindrical cell containing liquid hydrogen. outgoing hadrons were detected and identified in clas. momentum information for charged particles was obtained via tracking through three regions of multiwire drift chambers [ ] inside a prl , ( ) p h y s i c a l r e v i e w l e t t e r s week ending february - http://dx.doi.org/ . /physrevlett. . toroidal magnetic field (� : t), which was generated by six superconducting coils. the clas momentum resolu- tion is on the order of . – % (�) depending on the kinematics. the detector geometrical acceptance for each positive particle in the relevant kinematic region is about %. it is somewhat less for low-energy negative hadrons, which can be lost at forward angles because they are bent out of the acceptance by the toroidal field. the field was set to bend the positive particles away from the beam into the acceptance region of the detector. time-of-flight scintilla- tors were used for hadron identification [ ]. the interac- tion time between the incoming photon and the target was measured by the start counter [ ], consisting of a set of . mm thick plastic scintillators surrounding the hydrogen cell. coincidences between the photon tagger and two charged particles in the clas detector triggered the re- cording of the events. an integrated luminosity of about pb� was accumulated in days of running. in total, about tb of data were collected. the reaction �p ! �k k�n was isolated as follows. the k� was detected directly, and the ks component of the �k was reconstructed from its ���� decay. the momentum of the neutron was reconstructed from the known incident photon energy and measurements of all other particles in the event. calibrations of all detector components, and especially the tagger system, were performed achieving a precision of – mev in the nk� invariant mass determi- nation. the quality of the channel identification is shown in fig. where the �k and the missing neutron peaks are seen above a small background. reactions involving hyperon decays also contribute to the same final state. the most significant are �p ! k���� �! k� �k n, �p ! ��k���, and �p ! ��k���. these backgrounds are easily removed in our analysis with cuts around the known masses. they also serve as checks of our analysis procedure, e.g., by compar- ing their production cross sections with the world data. figure shows the background peaks: ��� � in the k� missing mass spectrum and the �� and �� peaks in the n�� and n�� invariant mass spectra, respectively. the mass region of each of these peaks was excluded from the final data set. after all cuts, the data sample contained approximately : � events out of the � in the original data set. the resulting nk� invariant mass distri- bution is shown in fig. . the spectrum is smooth and structureless. in particular, no evidence for a peak or an enhancement is observed at masses near mev, where signals associated with the �� were previously reported. to enhance our sensitivity to a possible resonance signal not visible in the integrated distribution, we considered the two-body reaction �p ! �k ��� � and selected differ- ent ks ( �k ) center-of-mass angle intervals. monte carlo studies of the clas acceptance for this reaction showed that we could detect events over the entire angular range ( – ), with some reduction of efficiency at forward angles (�c:m:�k < ). no structures were found in the dis- tribution when specific angular ranges were selected. since no signal was found, an upper limit for the �� production cross section in this reaction channel was ex- tracted. the unbinned nk� mass spectrum was fit in the range . – . gev using a maximum likelihood proce- dure, with the sum of a narrow gaussian function and a th-order polynomial that parameterizes, respectively, the �� contribution and a smooth background. to derive the corresponding event yields, the fitted functions were inte- grated over � around a fixed mass position. the fit procedure was repeated varying the resonance position from to mev in mev steps while the width � was fixed at . mev. this value was derived by monte carlo simulation assuming a negligible intrinsic width as suggested from recent analyses of kn scattering data [ ] and therefore dominated by the clas experi- mental resolution. the validity of the monte carlo simu- lations in reproducing the experimental data was checked by comparing the predicted with measured widths of nar- row states such as the �� and ��. the data set was independently analyzed by three groups, each one deriving an estimate of the �� and background yields. the three analyses differ in the reaction selection cuts, in the back- ground rejection criteria, and in the fit to the mass spectra. the three results were found to be consistent. they were combined by taking the average of both the signal and background yield, assuming totally correlated measure- ments. these values were then used to evaluate an upper . . . . . m = . gev σ = . gev mπ+π- (gev) c ou n ts /m ev m = . gev σ = . gev mx(γp → k k+ x) (gev) c ou n ts /m ev _ . . . fig. . top: ���� invariant mass and the �k peak. bottom: missing mass for the reaction �p !

�k �� ! ����k�n distributions were generated assuming five different �� production mechanisms: t-exchange dominance (the �k is mainly produced at forward angles in the center-of-mass system), u-exchange dominance (at backward angles), uni- formly distributed, and using the predictions of the model in ref. [ ] (with and without k� exchange process). for the t-exchange hypothesis we used the same angular dis- tribution as for �p ! k���� � production, which ex- hibits a typical t-channel forward peaking behavior [ ]. the u-exchange distribution was generated the same way but interchanging the center-of-mass angles of the �k and ��. the clas overall detection efficiencies obtained with different production mechanisms varied between . % for the t-exchange hypothesis and . % for the angular distribution of ref. [ ] when no k� exchange process is included. all the upper limits reported in this article were derived in the most conservative scenario, i.e., in the t-exchange hypothesis. the upper panel in fig. shows the upper limit on the total cross section as a function of the �� mass. an upper . . . . . . . . . . . . mΘ (gev) σ ( n b ) + % cl upper limit cosθcm d σ (n b )/ d co sθ c m % cl upper limit - - . - . - . - . . . . . fig. . the % c.l. upper limit on the total cross section as a function of the �� mass (top) and on the differential cross section d�=d cos� �k c:m: (bottom) for the reaction �p ! �k �� for an assumed �� mass of mev. the dotted line in the top plot is to guide the eye.

[ ] which reported a �� signal of events at a mass of mev corresponding to the published total cross section of nb. in order to better compare with that experiment, we repeated the analysis applying the same cuts reported in that paper: the photon energy was limited to . gev, only events with a forward-emitted �k (� �k c:m: > ) were used and no cuts were made to exclude hyperons. the resulting mass distribution is shown in the inset of fig. : it remains smooth and structureless. another way to show the incon- sistency of the two experiments is to compare the ratio of the upper limit of the number of �� with the number of the observed ��� �. applying again the same specific cuts to reproduce the saphir analysis, we evaluated a % c.l. limit on the �� yield of less than events. in the same photon energy range ( . – . gev) we observed � ��� �’s, compared with a �� yield of and ��� �’s, respectively, reported in ref. [ ]. the ratios obtained in the two experiments differ by more than a factor . in conclusion, this is the first result of a dedicated set of high-statistics and high-resolution experiments undertaken at jefferson lab to elucidate the debate on the existence of the pentaquark. the reaction �p ! �k k�n was studied in search for evidence of the �� pentaquark in the nk� decay channel. the final state was isolated detecting the k�, the �k by its ���� decay, and identifying the neutron by means of the missing mass technique. the direct mea- surement of the k� allows one to define the strangeness of any baryon resonance observed in this final state. the nk� mass distribution was found to be smooth and structureless. no evidence for a narrow resonance was found in the mass range – mev. an upper limit of . nb ( % confidence level) on the total production cross section for a �� mass of mev was set. this is in disagreement with previously reported evidence for a resonance in the same reaction channel, and sets stringent upper limits on the models which predict these long-lived pentaquark states. we would like to acknowledge the outstanding efforts of the staff of the accelerator and the physics divisions at jefferson lab that made this experiment possible. this work was supported in part by the italian istituto nazionale di fisica nucleare, the french centre national de la recherche scientifique and commissariat à l’energie atomique, the u.s. department of energy and national science foundation, and the korea science and engineering foundation. the southeastern universities research association (sura) operates the thomas jefferson national accelerator facility for the united states department of energy under contract no. de- ac - er . *current address: university of new hampshire, durham, nh - , usa †current address: old dominion university, norfolk, va , usa ‡current address: massachusetts institute of technology, cambridge, ma - , usa xcurrent address: university of south carolina, columbia, sc , usa kcurrent address: physikalisches institut der universität gießen, giessen, germany {current address: university of massachusetts, amherst, ma , usa [ ] t. nakano et al., phys. rev. lett. , ( ).

thomas jefferson memorial (tjm), in washington d.c. reveals an astonishing rhetorical secret, hidden in plain sight in the form of one of america’s most visited, and high-profile, national monuments. upon the marbled interior of this washingtonian pantheon, brass lettered quotations from jefferson’s works, epistles, and legislation, purport to communicate an accurate and accessible facsimile version of the third president’s intellect, philosophy, and politics. comparison of the quinquepartite panels to the original documents authored by jefferson, however, exposes a systematic and purposeful series of textual and semantic alterations, giving rise to a highly manipulated form of us national history, presidential memorialization, and public understanding. this thesis moves in three parts: ) to establish the existence and extent of these manipulations; ) to interrogate the means and agents of jefferson’s mediation; and ) to assess the material and symbolic consequence of the tjm’s continued presence in extant form. in so doing, this thesis finds that the inscriptions of the jefferson memorial were knowingly edited to function not only as a subjective commemoration of a national political hero, but also as an item of contemporary progressive propaganda, communicating messages consistently sympathetic to roosevelt’s new deal and wartime agendas. accordingly, the monument becomes an important locus for investigating the specific rhetorical formation and consequence of a single (and highly motivated) public memory space, whilst also providing a replicable case study methodology for a broader derivation of the workings of “technologies of memory” (as defined by sturken, ), as they function at political mnemonic sites in the u.s. and beyond. informed by rhetorical theory, studies in public memory, and intensive archival research, this investigation forms a rhetorical criticism of the tjm, with particular emphasis on the unearthed the thomas jefferson memorial commission: general records, - . record group : records of the national park service, - . ( files) arc: (national archives, md) fallacies of the inscriptions as one element of that material and symbolic rhetoric. the archive provides hitherto unreported documentary evidence of the role, motivations and consequence of the thomas jefferson memorial commission (tjmc) and its most senior and energetic patron, president franklin delano roosevelt, acting together as the rhetorical agents of jefferson’s reconceptualization, and codifiers of his public voice and history. an assessment of the tjmc’s method of textual selection indicates the extent to which the monument formed a potentially partisan and activist presidential memorialization, to the detriment of public understanding. evidence suggests that the memorial, and its constituent inscriptions, was appropriated to form a contemporary rhetorical object that ventriloquized jefferson to suit the political philosophy of roosevelt’s administration and an interpreted narrative of s- s america. the tjm is rhetorical attestation of jefferson’s continuous re-situatedness and of the forced malleability of his contested historical persona over time by those claiming (parts of) his legacy at tendentious moments (adams, ; ellis ). given the celebrity status of jefferson as a founder of american political thought, it is not surprising that he has been variably borrowed by academics, biographers, and politicians over the centuries as the historical prime mover of particular causes or movements. at the time of the memorial’s creation, roosevelt and the progressive movement adopted jefferson as the standard bearer of civic humanism and government-led social reform. according to paul zummo ( ), for example, “[t]he great depression, franklin roosevelt’s ascendancy, and the new deal reawakened the progressive impulse, and the spirit of the progressive movement – itself a manifestation of the jeffersonian political philosophy” ( ). the memorial commission, populated almost exclusively by democratic representatives – and acting as rhetorical sub-agents with political allegiance to roosevelt – were presented with an opportunity to write jefferson-the-progressive into the material and cultural fabric of the united states commemorative narrative. the discovery of the memorial’s de facto inaccuracy will be, for many, a matter of prima facie scholarly and public significance, under the unspoken, but persistent, motto of academic discourse: omne ignotum pro magnifico. yet that conversation gets only to the physical act of the memorial’s creation and its partiality, not to the more interesting (and rhetorical) question of the motives involved in the particular ways the memorial was rendered so. this study might loosely align itself with the dramatistic methodology of kenneth burke, in understanding the creation of the memorial (and its inscriptions) as a high-profile communicative action – or text – with complex and powerful motivational provenance and consequence (burke, ).the interpretative philosophy of the dramatistic pentad – burke’s principal construct for the investigation of human motivation – moves us beyond the monadic declaration of misquotation and into the interrogation of act, as well as scene, agent, agency, and purpose (burke, xv). the memorial can be understood as (evidence of) the rhetorical act itself, whilst the remaining elements of the dramatistic pentad can be derived from a thorough analysis of the archival material of the tjmc. here, exhaustive correspondence among members of the commission, agencies, the white house and others, alongside commission minutes, memoranda, designs, and submissions, reveals multivariate motivational forces and their interaction with the scene of mid-twentieth century socio-political attitudes. the memorialisation, therefore, is recognised as a product of a tangled cultural remembering; its (un)reliability forms the keystone for fathoming the interactive “desires, needs, and self-definitions” (sturken, ) of an american culture that created, and continues to validate, it. this study employs the lens of marita sturken, who (invoking foucault’s technologies of the self) defines memorialising objects, from monuments to yellow ribbons, as “technologies of memory” ( ), shifting the emphasis from the nature of the technology itself, to the process and source of that technology’s instrumented deployment by agents within a material (and invariably political) context. memorials are unavoidably – and axiomatically – rhetorical. studies in public memory, visual art and rhetorical theory (in response to the “discursive turn” ) have, following burke, established ‘everything unknown appears magnificent.” the “discursive turn” (also “rhetorical turn”) is widely understood as a challenge to the objective or scientific interpretation of the rhetorical form. in short, the core proposition of the discursive turn is that rhetoric is always meaning-making, effecting and memorials, museums and collective memory spaces as rhetorical acts (or texts), upon scenes, by recognised agents with discernible motivations. ehrenhaus ( ) recognises memorials as legitimate rhetorical texts because they are used for persuasion and propaganda, sponsored, endorsed or constructed by governments or their proxies, so that they might be read as inventions of institutional authority, or the expressions of political bodies in (re)conceptualising historical events. ( - ). gallagher ( ) writes, “[s]uch artifacts are intended by their creators and/or perceived audiences to perpetuate values, admonish us to future conduct, and affirm or challenge existing power relations” ( ). conversely, carruthers ( ), whilst recognising that “memorials are rhetorical…powerfully so,” notes that they are so “whether or not their designers and patrons intended them to have such rhetorical power.” according to her, “it is unlikely that the designers of the lincoln or vietnam [and we can assume other major] memorials thought in terms of rhetoric at all; probably they would be offended at the very idea” ( ). this thesis, with evidentiary support from the archive, aligns itself with the theories of agential purpose espoused by ehrenhaus and gallagher, whilst severely departing from carruthers’ claims of mediators’ rhetorical naiveté or innocuous political agency. part of the power wielded by the rhetors, or creators, of a public memorial is the manipulation not only of what a society remembers, but also of what it forgets, as referenced by sturken ( ), dacres, ( ) and ehrenhaus ( ). this is achieved, according to biesecker ( ), perelman and olbrechts-tyteca ( ), young ( ) and griswold ( ), as memorials function in epideictic or didactic rhetorical modes. by invoking the blame and praise dichotomy recognised by aristotle in his very definition of epideictic rhetoric, commemorations can “function rhetorically as civic lessons for a generation beset by fractious disagreements about the viability of u.s. culture and identity” (biesecker, affecting the realities and culture(s) of its participants. jack selzer ( ) and other have challenged the “discursive turn” and its concentration on the ephemeral, to underscore that an object’s material aspect is a dynamic component of rhetoric, meaning and culture. ). memorials such as the tjm are explicitly epideictic vehicles for employing national patriotic stories of “ennobling events” (young, ) for modern repossession. this thesis also follows the recent re-consideration of a material rhetoric (by sturken et al), whereby recognising rhetoric as substantial in itself – and not simply attending to the materiality of the rhetorical context – moves us to consider the memorial as a legitimate text outside of the narrow definitions of written and oral discourse. much of the intellectual space for a material rhetoric as applied to public memory in physical space was chartered by carole blair in the wake of the fifteenth penn state conference on rhetoric and composition ( ). having identified the postmodern, post- structuralist era as the kairotic moment for a material rhetoric, blair applies five modes of inquiry to her (admittedly curtailed) case studies from a post- memorialising culture. first, what is the significance of the text’s materiality? second, what are the apparatuses and degrees of durability displayed in the text? third, what are the text’s modes or possibilities of reproduction or preservation? fourth, what does the text do to (or with, or against) other texts? fifth, and most importantly for the heuristic of materiality, blair asks how does the text act on person(s) ( ). such questions, sufficiently adapted, will be deployed in the final chapter to assess the consequence of the misleading jefferson epigraphs upon the material and cultural context. in places of public memory ( ), dickinson, ott, and blair situate modern memory studies in a post-halbwachs, post-foucault context, in which memory is broadly understood as an operation of collectivity, “rather than individuated cognitive work” ( ). following hattenhauer ( ), dickinson, blair and ott argue that interaction with a site’s materiality “predisposes its visitors to respond in certain ways, enthymematically prefiguring the rhetoric of the place as worthy of attention, investment, and effort (at the very least)” ( ). arguably, the tjm engages in a fallacious rhetorical relationship griswold has similarly identified the lincoln memorial as a site of epideictic rhetoric, rendered in the traditional “pattern of a hero,” conveying the lincoln-as-saviour motif for replication among the american public. throughout her chapter in rhetorical bodies and other scholarship, blair has avoided the substantial washington memorials (lincoln, jefferson and washington) of the late-nineteenth and early-twentieth centuries. with its audience, enacting a betrayal by subverting the expectation of an accurate and authentic presidential memorialisation. finally, this thesis recognises the important observation of james loewen in underlining the tripartite historic dimension of objects of public memory, such as the thomas jefferson memorial. the first phase is the “manifest narrative” of the original event or person, that is to say the historical genesis to which the object refers ( - ). the second phase is the story of the site’s own creation, the historical circumstance of the object’s mediation which “reflect[s] the attitudes and ideas of the time when americans put them up, often many years after the event” ( ). the final historical moment is that of a visitor’s own contemporary experience, by which the manifest narrative is activated within the confines of a particular context. in summary, this thesis understands memorials such as the tjm to be legitimate texts subject to rhetorical motivational forces, used for political propaganda, and constructed for discrete remembrances and amnesias. they employ national stories for modern repossession. they are materially consequential objects which act upon audiences and influence other texts and interpretative discourses over time. memorials are also acts of collective cognitive work that predispose their audiences to receive accurate and authentic information. these characteristics of memorial objects provided the rhetorical mechanics for the thomas jefferson memorial commission to engineer a version of jefferson’s legacy to agree with the agenda of his democratic inheritor and primary commemorative sponsor: franklin delano roosevelt. in chapter , close analysis of the five inscriptions and the archival record reveals that the thomas jefferson memorial commission embarked upon a series of purposeful and recontextualizing revisions. in each case, the editing process achieves some level of alignment between the memorial’s subject and its patron. examples include the generalisation of jefferson’s political philosophy to serve as an apposite war cry against tyrannical injustice and religious oppression, the use of selective quotation to suggest jefferson’s support for the scope of governmental overhaul represented by roosevelt’s new deal, and the extrapolation of a comment jefferson made on educational provision to an unequivocal endorsement of universal public education. during the consideration of one panel, the commission simplifies and ameliorates jefferson’s complicated relationship to the abolition of slavery, while also wrestling with the question of whether any reference to jefferson and civil rights might be problematic for roosevelt’s administration (which, whilst contributing significantly to the advancement of african americans, also compromised parts of its civil rights agenda to maintain the political support of southern white democrats). chapter examines the competing motivational forces behind the mediation of jefferson via the manipulation of the memorial’s epigraphical content. specifically, archival research exposes the motivations of the commission and the sub-committee on inscriptions in (re)creating the historical voice of jefferson for public commemoration. this historicizing project competes with the direct intervention of president roosevelt to ensure a parallelism between his contemporary agenda and the legacy of jefferson as a progressive icon. chapter examines the memorial from a material-rhetoric perspective in order to understand how it achieves the goals of its rhetors, as well as a variety of unintended (or unforeseen) consequences in shaping public memory. the memorial engages its users in an enthymematic deceit, which presents an inauthentic version of jefferson as a supposedly elite, accurate and authentic object of public memory, worthy of attention, investment, and effort. chapter : the rhetoric – from parchment to marble, jefferson reclaimed thomas jefferson, who had designed his own modest tombstone during his lifetime, could hardly have imagined the scope of his eventual posthumous memorialisation. rising feet higher than the obelisk of coarse stone he had envisaged, the thomas jefferson memorial upon the south bank of the tidal basin is today an extravagant, brobdingnagian shrine to the third president of the united states and his interpreted ideals (appendix a). the design, informed by the roman pantheon and jefferson’s own architectural tastes, is unashamedly neo-classical, modelled by leading antiquarian architect john russell pope. facing the washington monument and the white house beyond, the main entrance of the memorial consists of sweeping marble steps leading to a portico with a circular colonnade of ionic order columns rising feet high to support a pediment containing a sculptured representation of the signing of the declaration of independence, crowned by a shallow dome. the interior of the monument is demarcated by four great stone panels on the northeast, northwest, southeast, and southwest walls, as well as a carved panel that encircles the base of the dome’s interior. each quadrant features a prominent brass-lettered epigraph, apparently taken from jefferson’s own writings, communicating a concentrated and accessible version of jefferson’s intellect, philosophy and politics. the content of these panels is illustrated in appendix b. this chapter recognises these inscriptions as part of the grammar of the memorial’s rhetorical whole, functioning as examples of the classical concept of “relative inscription” – i.e., epigraphical content bearing relationship to other rhetorical features of memorialisation to communicate a particular narrative or theme. those responsible for the creation of the tjm relied upon the manipulation of these inscriptions to fashion a reality of jefferson’s thinking which corresponded with – if not historically validated – a number of the policy decisions and rhetorical frameworks of the roosevelt administration itself. by number alone, analysis reveals that a total of (at least) ten separate textual sources were marshalled by the commission to compile only five panels, demonstrating the extent of creative license at work. the nature of this rhetorical manipulation is distinct for each panel, but the overall intent is largely consistent and well-evidenced: that is, to extract from jefferson’s often context-dependent, nuanced and problematic source texts, quotations that are generalised and aphoristic; applicable to world war ii dichotomies; and supportive of the new deal philosophy. the commission edited the inscriptions to simplify jefferson’s enigmatic qualities as an historical actor, by, for example, christianizing his voice (where greater theological complexity exists) and – most significantly – transforming the ideological minefield of jefferson’s record on slavery into declarations of unwavering and prophetic abolitionism. the story of each inscription’s formation is detailed in turn below, demonstrating the cumulative mechanistic and ideological manipulation of the source text material to effect an opportunistic interpretation of jefferson for the benefit of his rhetorical agents and their context. whilst it is clear that any truncation of jefferson’s language is a fraught experiment of semiotics, the commission’s accommodation of roosevelt’s presidential license leads to a codification of jefferson’s character that, at times, is both opportunistic and counter-historical. thomas jefferson memorial panel a (tjmpa) the quotation on the panel of the base of the interior dome (hereafter tjmpa) is, in fact, the only engraving of the five major quotations found within the memorial room, with the other four consisting of individually laid brass letters. comprising only twenty words, “i have sworn upon the altar of god eternal hostility against every form of tyranny over the mind of man,” the quotation runs around the entire circumference of the circular chamber, emerging from the right side of jefferson’s statue; its end and beginning points are demarcated only by three engraved saltire crosses – exaggerated terminal punctuation for greater legibility. as archival analysis reveals, the quotation against tyranny was selected, on the one hand, as an interpretative keystone for the entire memorial. the sentence functions as the generalising and encompassing parent-thought of american freedom to encircle and unify the quadrants’ endorsement of a variety of human freedoms. on the other hand, the commission significantly and knowingly recontextualized what was originally a private remark on personal electoral and theological rivalries, making it a cosmically proportioned proclamation of liberty. the commission therefore concentrated jefferson’s original subtlety and specific concern into an aggrandising aphorism that a) distilled jefferson’s historical persona as the prime mover of america freedoms, b) supported the current western response to the existential threat of nazism’s rise, and c) roused and comforted an american public by re-emphasising the existential semantic of is founding democratic philosophy. the quotation is taken entirely from a private letter written by jefferson (in monticello) to dr benjamin rush, dated september , , in which he defends his philosophical rebuttal to the enshrinement of state religion (boyd : ). the missive was written at a crucial point in american political history, on the eve of the antagonistic presidential election in which jefferson and his running mate, aaron burr, (on a democratic-republican ticket) campaigned against the incumbent federalist, john adams. the election was bitterly fought, with divisions on foreign policy – particularly attitudes towards the virtue or villainy of the french revolution – looming large in public debate. jefferson’s ultimately successful campaign was also dogged by accusations surrounding his religious (deistic) beliefs. his numerable critics voiced concern that his abstraction from mainstream christian orthodoxy made jefferson unfit to hold the highest office, and a threat to their congregations. this letter, from which the prominent quotation is taken, is, in fact, a response to a warning from rush – written august – about the strength of anti-jeffersonian feeling among the philadelphian clergy (and others) who continued to cast the candidate as a dangerous atheist. the wall of separation between rush was no doubt reading the same arguments captured in an article from the new england palladium: “should the infidel jefferson be elected to the presidency, the seal of death is that moment set on our holy religion, our churches will be prostrated and some infamous prostitute,…will preside in the sanctuaries now devoted to the worship of the most high.” church and state – a philosophy articulated by jefferson, and acted upon through his work in virginia to disestablish religion – had garnered extreme opposition and was becoming a partisan and theological issue. in the third paragraph of this letter, jefferson counters the logic of his pennsylvanian foes by interpreting their opposition to him as a misunderstanding of the “clause of the constitution, which, while it secured the freedom of the press, covered also the freedom of religion” and “had given to the clergy a very favourite hope of obtaining an establishment of a particular form of christianity thro’ the u.s.” jefferson’s potential election to the presidency threatened to thwart such an enshrinement, as his enemies believed that “any portion of power confided in me, will be exerted in opposition to their schemes.” it is here, at the crest of a political riposte, that the tjmpa quotation is found: and they believe rightly; for i have sworn upon the altar of god, eternal hostility against every form of tyranny over the mind of man. but this is all they have to fear from me: & enough too in their opinion & this is the cause of their printing lying pamphlets against me (boyd, : ). the quotation, as it appears upon the memorial frieze, is arguably the most faithful textual replication of jefferson’s words within the epigraphical whole. while it omits the sentence’s beginning, the quotation does not otherwise deviate significantly from the primary source, nor is it combined with any other source material. grammatically, the comma from the initial clause has been removed, and the lowercase “god” is rendered imperceptible by the total capitalisation of the sentence, as is customary for the majority of memorial inscriptions to maintain aesthetic balance (and also potentially convenient for avoiding theological controversy). instead the commission’s formation of tjmpa exemplifies a number of rhetorical fallacies under the broad terminology of recontextualization, a process defined by per linell as “the dynamic transfer and transformation of something from one discourse/text in context . . . to another” ( ). the commission abstracts jefferson and his language (the historical manifest narrative) – with intent – from an original context and, via the rhetor-agency of an early-twentieth century commission supported by the president, into a discrete alternative milieu. the inscription of tjmpa is a significant event of fallacious contextomy, or quoting out of context, in order to wrench the words away from their realpolitik, epistolary and theological context towards a new kairotic moment of generalising twentieth-century american resistance to oppressive regimes and tyrannical ideologies. the original letter, with its climactic rebuttal to jefferson’s political enemies, is a deeply context-dependent document, rich in reference to late eighteenth- and early nineteenth-century presidential politics, international affairs and constitutional philosophy. the letter forms part of a dialogic correspondence between two of the nation’s founding fathers on the subject of christianity and political strategy. recontextualized by the commission as it is – and dislocated from the realm of private discourse to public and international consumption – the statement is denuded of complexity and emphasis, so that the words are rendered as a stand-alone affidavit of the unerring philosophy of divinely witnessed american freedom. while there is no doubt that this sentiment exists in jefferson’s original, the quotation erases the constitutional backdrop that provokes it. rather the quotation drapes jefferson in a cloak of heroic christianity as some miles christi – potentially the antithesis of his original intent. under the agential influence of the tjmc, the oath sworn upon the altar is no longer the rhetorical retort to the oppressive potential federalist pamphleteers, but the sober religious staging for jefferson’s rejection of (now ill-defined, and thus potentially reclaimable) general tyranny. the inscription, installed upon the memorial as an isolated maxim, demonstrates the potential for the logical fallacy of contextomy to effect an entirely false attribution of values, to provide the phrase with a philosophical pregnancy not present within the source text. these words have significant bearing upon the interpretative framework of the memorial, and its constituent inscriptions, arguably serving as a keystone of misremembering. the commission archives illuminate the complex of motivational forces working upon the rhetor-agents who moved to adopt the frieze quotation. dr fiske kimball first suggested the use of the rush letter quotation at the meeting of the commission on march , , bolstering his selection of the frieze statement with an intriguing appeal to informal presidential authority and approval, suggesting that roosevelt had in some way already commended the quotation for the outlined application: i found one which you have seen before that i know the president would like very much. “i have sworn upon the altar of god eternal hostility to every form of tyranny over the mind of man.” i would like to see it run along the frieze (tjmc- ). on october , , the tjmc met to debate the wording for the frieze quotation, eventually moving to adopt the rush-letter phrase as the memorial’s banner epigraph. it was propelled to debate at this moment by contractual impetus, prior to the establishment of the formal sub-committee responsible for later inscription selection. from the beginning, the quotation was conceived by the commission as a purposefully undefined axiom, extracted from the particulars of jefferson’s electoral context to serve as a grandiloquent universal proclamation on liberty, under which each of the other quadrant panels could find a unifying theme. dr kimball made the generalizing stratagem clear, understanding the phrase as having the “advantage over all other excerpts, in that while he has elsewhere expressed his hostility to political tyranny, or religious tyranny or other forms of tyranny, in those words he covered all forms of tyranny” (tjmc- october , ). the leaflet prepared to attend the public opening of the memorial affirmed the quotation’s generalising properties in summarising the “creed of [jefferson’s] political and social philosophy” (tjmc- ). senator thomas, an appointed member of the tjmc, heaped praise upon the inscription in october for its potential to be an all-encompassing headline: “i do not know what better quotation you could get to show what an american democracy stands for” (tjmc- ). the commission transforms the electoral and constitutional threat of christian federalist activists, which jefferson describes as a form of tyranny within the complex of his own political battle, into the altruistic, statesmanlike remonstration of individual oppression. the recontextualization causes the twenty-word phrase to serve metonymically for the jefferson corpus and a rooseveltian brand of american foreign policy. tjmpa might be understood less as a signification of the historical object (and his unorthodox religious views), and more a means of deploying that historical object within the circumstantial zeitgeist of cultural memory. in the words of sturken (writing on other sites of commemoration), the memorial’s “authenticity is derived not from its revelation of any original experience but from its role in providing continuity to a culture” ( ). at the moment of the memorial’s creation, the continuity of american culture and democracy faced its greatest existential threat from the rise of european fascism. correspondingly, the archives reveal that the intent of the quotation was less to remember who jefferson was for posterity, and more to ensure that a public did not forget what america meant for interbellum modernity. the quotation was brought to the commission’s attention by dr fiske kimball, with the potency of implied presidential authorization. almost one year later roosevelt contacted chairman gibboney by memorandum, proposing the very same quotation from the benjamin rush letter for the dome inscription, forwarding a supporting letter from secretary harold ickes – a key implementer of the new deal agenda. “what do you think of this idea?” the president asked, before underscoring, “it seems pretty good to me. fdr” (tjmc- december , ). gibboney reassured roosevelt that “this has already been done, as mr ickes can see if he visits the memorial,” before inviting further involvement from the sitting president, “to select the most suitable quotations for these panels, and we should be most happy to receive from you any suggestions you might care to make in this connection (tjmc- december , ). whether roosevelt was merely measuring the potency of his earlier implicit endorsement of the sentence, or his general sway with the commission, (or indeed even if the entire matter had been coincidence) his preference for the tjmpa was secured, along with his power as an interceding rhetor with demonstrative agency in a project of jeffersonian recontextualization. the motivation behind roosevelt’s intervention was to memorialise a contemporary brand of american liberty, against the current context of hitlerism’s rise, via the abstraction of jefferson’s words. throughout his world war ii rhetorical output, roosevelt relied upon the re-interpretation of jefferson as an historical antecedent to his own administration and its challenges. when speaking about the protection of the american maritime borders from german invasion in , for example, roosevelt called upon the exemplar of jefferson’s order to the navy to end the attacks on american ships by the corsairs of the north african nation ( ). the alignment of jeffersonian liberty with roosevelt’s contemporary protection of it was repeated throughout the s, and in the president went so far as to adopt and redefine the interpretative framework of jefferson’s “four freedoms” within his state of the union address (pederson, ). in the words of katherine scarborough, the frieze quotation was “selected for perpetuation before the eyes of the world at an hour when the right of human beings to think for themselves has been denied to millions, and, where it survives, is challenged more seriously than ever before in history” (december , ). the sentence is recontextualized (with discernible intent) from jefferson’s political battle against religious intolerance, to an international struggle against fascism and dictatorships, and from an audience of one in , to a global audience of millions during the uncertainty of international warfare. in , senator thomas – referring to the frieze quotation – exclaimed: “i only hope that they will charge this sentence up to each member of the commission, and we can all take credit for writing it.” beneath the jocularity of this statement is a self-revelatory truth. the commission members, as well as roosevelt, rewrote jefferson’s political statement through the formation of their own rhetorical object, forgetting, and forcing others to never properly understand, the intent, context and scope of the manifest object. thomas jefferson memorial panel b (tjmpb) the engraving on the quadrant panel of the southwest interior wall (hereafter tjmpb) is similarly derived entirely from a single source, namely the american declaration of independence ( ). widely recognised as the most influential document in the history of the united states, and ubiquitous in every classroom as the originary rhetoric of the republic’s freedom, the declaration is the metonym for the american consciousness – an “expression of the american mind” (jefferson ) as its author described it – and understood as the centrepiece of jeffersonia. it is perhaps evermore striking, then, as central as these words are to the foundation of american democracy and the formation of public memory surrounding jefferson, that in their quotation there is evidence of significant truncation and deviation, leading to false attribution, contextomy, and the fallacy of incomplete evidence, when compared against the source text. archival evidence suggests that the manipulations of the declaration of independence involved the selective redaction of those clauses least transferrable to contemporary foreign policy challenges. roosevelt directly intervened to emphasise a (wartime-friendly) statement on the sacrifice of life required to protect american freedoms. this is achieved to the detriment of the document’s context and innate artistry. the changes made to the declaration for the purposes of inscription are perhaps not the most egregious textual manipulations of the five panels, but they are certainly the most audacious when one considers the eminence of the original. when compared with the signed parchment version housed in despite their ease with their own misquotations of jefferson, the commission attempts to tightly control the interpretation of the jefferson memorial and to limit the multiplicity of individual readings. when deciding upon the frieze quotation, for example, senator thomas forensically examined the collocation of the inscription’s letters to assess what alternative readings might be made from various starting points. “let us see,” he said without irony, “what they [the public] could twist it into” (tjmc- – october , ). the national archives, the memorial text (tjmpb) includes quotations from only two of the five main sections of the declaration. incorporating the language from the preamble and the conclusion, the quotation omits any reference to the introduction, the indictment of george iii, and the denunciation of the british people. it is a quotation of the declaration’s ceremonial and more generic bookends, avoiding the more specific and enumerative contents of the text’s middle section, so as to maximize the applicability of its theoretical principles. comparative analysis reveals a number of (signalled and hidden) alterations made by the commission in their attempts to adapt the source text for maximal relevance. at the end of the first phrase in line , for example, “self-evident” is followed by a colon (rather than the comma used in the source text) providing a more revelatory pause to the subsequent enumeration of natural rights. in line , the subordinating conjunctive “that” preceding the enumeration of life, liberty, and the pursuit of happiness, is eradicated, disrupting the anaphoric flow of the opening sentence. at line , the tjmpb version denudes “these colonies” of the modifying “united.” in the antepenultimate line, the conclusive declaration (“we mutually pledge our lives”) omits the specification that this pledge was made “to each other,” arguably molding it for roosevelt’s era of international conflict and military sacrifice. similarly, line marks the transition between the preamble and conclusion of the declaration, yet despite the significance of this textual discontinuity, there is no explicit ellipsis in the southwest panel. the transition between the two sections is problematized further by the terminalisation of the preamble, which excludes the right of revolution argument at the very heart of the declaration’s rejection of tyrannical rule. these changes, invisible on the memorial inscription, are a means to an end in drawing out applicable messages, and expunging others. for the current administration, reliant upon internal cohesion of the democratic party, the erasure of the revolution principle is a potentially calculated act of self-preservation. as the quotation moves to incorporate language from the declaration’s concluding paragraph, the textual alterations continue, including the omission indicated by the line ellipses. in the commission’s recontextualization of the source text for modern repossession, the plural pronoun “we” loses its original reference to congressional representatives: we, the representatives of the united states of america, in general congress, assemble…do, in the name, and by authority of the good people of these colonies, solemnly publish and declare. consequently, and rhetorically, the specific contextual strings to which the declaration was anchored – and which were complemented by the current debate and congressional vote – are cut from the memorial version. the inscription is subject to a process of broad generalisation, through which moral principles (freedom, equality, just government and personal and states’ rights) are extracted and decontextualized, in order that they can be successfully resituated in any future american period as embodying the strength of the imperative, yet redacted of george iii and his specific tyrannies. in the quotation, the identity of the american enemy is anonymized and the potential for historical resonance expanded, such that the tyranny of an english king is made relatable to the oppositional frameworks not only of world war ii, but, for example, the cold war, vietnam, and the modern war on terror. as a new re-interpretative object of public memory, the quotation is made available for generational reclamation, so that portions of jefferson’s political philosophy are (or can be) effectively ventriloquized for the posthumous events which extend beyond the scope of his biography. from the earliest inception of the memorial, the commission considered the declaration as having a prima facie right of inclusion. it had the virtue of being the primary document that jefferson included in his modest self-memorialisation at monticello, and it was identified in foley’s jeffersonian cyclopedia as one of his most substantial legacies. as the commission archives reveal in startling – and hitherto unreported – detail, the gross manipulation of the source document and the consequent distortion of jefferson’s voice was the sole result of the interruptive force of roosevelt and the commission’s subsequent attempt to accommodate that high-profile agent’s power. if roosevelt’s influence upon the selection of the quotation for tjmpa had to be inferred, his involvement in the composition of tjmpb is overt and well-evidenced. in mid-december , roosevelt was invited to initiate the construction project at the site of the prospective memorial. prior to the official ground-breaking, the president spoke of (and accordingly framed) jefferson’s meaning to his contemporary american public with direct reference to the declaration: jefferson… has been recognized by our citizens not only for the outstanding part which he took in the drafting of the declaration… not only for his authorship of the virginia statute for religious freedom, but also for the services he rendered in establishing the practical operation as a democracy and not an autocracy (washington herald, december , ). this statement pre-empts the ultimate inclusion of both the declaration and the virginian statute as permanent memory prompts within the textual corpus of the memorial room. posing the democratic ideals of jefferson against that final antonymic word – “autocracy” – would have undoubtedly resonated with a listening public upon the precipice of autocratic incursions in europe. less than a year later and speaking at the cornerstone-laying ceremony, roosevelt made the elision of jefferson’s political environment and his own era of power explicit: “he lived as we lived in the midst of struggle between rule by the self-chosen individual or the self-appointed few, and rule by the franchise and approval of the many” (tjmc- november , ). roosevelt’s attempts to publicly parallel jefferson with his own presidency were matched by private machinations that sought to influence the commission to do the same via the rhetoric of tjmpb. in may , gibboney wrote to roosevelt, making good on a promise that “i would send you a copy of the proposed inscriptions for your suggestions... we should be very glad to have your criticism at your convenience” (tjmc- ). though roosevelt received the letter only two weeks before he was to declare an unlimited national emergency, he responded immediately, giving his approbation to the work achieved so far whilst indicating a preference for amending tjmpb: i do miss the last paragraph of the declaration of independence. it seems to me that that is so familiar and so important that it should appear somewhere. it could be condensed somewhat as follows: “we . . . solemnly publish and declare, that these united colonies are, and of right ought to be, free and independent states . . . and for the support of this declaration, with a firm reliance on the protection of divine providence, we mutually pledge to each other our lives, our fortunes, and our sacred honor” (tjmc- may , ). here, roosevelt goes so far as to model the quotation, with ellipses and editing, to ventriloquize jefferson in an era of echoic competition between the values of american democracy and those of european autocracy. a number of days later, general kean responded to the intercession with mixed feelings, agreeing that the addition would “round it out very nicely” whilst being surprised at the “continued interest which the president takes in the memorial in spite of the tremendous responsibilities which he is facing on matters in which the whole world awaits decisions” (tjmc- may , ). indeed, the physical act of war and the rhetorical act of the memorial’s might be interpreted as thematically contemporaneous in roosevelt’s thinking, each functioning as defensive statements of the american ideal. practically, however, roosevelt’s suggested alteration to the panel’s length, emphasis and continuity, delivered under the seal of the president, sparked fractious debate among the tjmc members and the architectural firm, eggers and higgins. in particular, the changes to the content already agreed upon by the sub-committee on inscriptions, threatened to distort the visual balance of the four quadrants. the commission faced a genuine quandary of priorities, between effectively memorialising jefferson in accordance with their collective reasoning, and acquiescing to the power- laden intercession of his th century successor. in august , the architect’s design team revised tjmpb “to show the arrangement under these circumstances,” but eggers explicitly disapproved: “i have a feeling that the memorial might in part fail in its purpose if the inspiring words of jefferson were not read and absorbed by the majority of visitors… this would mean that substantial additions would have to be made to the other three panels if the president’s suggestion is carried out (tjmc- september , ). over the next few weeks, gibboney manoeuvred the commission out of a potentially embarrassing impasse. invisible to commission minutes and the papers of tjmc archives, the panel was significantly revised to accommodate the president’s suggestion. general kean praised the “very clever and satisfactory” compromised arrangement, which “met the president’s wishes, got rid of those troublesome words “or abolish it” and gives a satisfactory length for mr eggers” (tjmc- , october , ). the president subsequently approved of the resolution, adding “i like the way you have worked out the inscription” (tjmc- , october , ). demonstrably, almost all of the major textual deviations were incurred and documented as a cost of obliging presidential intercession. senator thomas viewed the concession as a consequence of short-sighted politicking via the back door of jefferson’s memorialisation, codifying the moral rightness of the incumbent rather than his predecessor: i… am loth to disagree with the president’s wishes, but the last words of the declaration which we have added on panel one are merely an appeal to support a cause – a great cause, of course, but there is not a bit of political theory in it. men fighting on hitler’s side today have mutually pledged their lives, their fortunes, and their sacred honour, and are giving them! that was america as a war cry, not jefferson as a political philosopher (tjmc- october , ). the consequence of roosevelt’s attempted historical parallelism is significant also for what it effects upon the public remembering of jefferson as a meticulous political author. roosevelt’s panel, adopted by the commission, is injurious to the modern interpretation of the declaration as an exemplum of eighteenth-century constitutional prose, wrought with rhetorical precision and enlightenment style. the declaration is a paragon of concentration and restraint, with individual propositions, phrases, and words irreducibly essential to the document’s force and meaning. it is a treatise brought to the scale of paragraph. on the artistry of the declaration, stephen lucas writes the following: each word is chosen and placed to achieve maximum impact. each clause is indispensable to the progression of thought. each sentence is carefully constructed internally and in relation to what precedes and follows…one word follows another with complete inevitability of sound and meaning. not one word can be moved or replaced without disrupting the balance and harmony of the entire preamble ( ). illustrative of this point is the way in which the preamble was conceived as an extended deployment of an elaborate rhetorical device – an ascending pentacolon– through which the compounding of five sequentially dependent propositions (cola) ascend towards a powerful and inevitable conclusion. jefferson was au fait with the eighteenth-century periodic style of rhetorical construction – including an informal sorites, or polysyllogistic construction – whereby “sentences are composed of several members linked together, and hanging upon one another, so that the sense of the whole is not brought out till the close” (blair , ). embedded within the preamble are five interconnected and progressively dependent propositions that move to justify the emphatic climax of revolution. throughout these propositions, the structure is dependently chronological – perhaps even biblically so, moving from an act of creation, to the implementation of order, to chaos (rebellion), and to the institution of a new redeeming governmental order. the pentacolon then, writes the fates of american readers in a fabled five-part chronology of american history. to this considered filigree, the commission take a metaphorical butcher’s cleaver, whereby incorporating the president’s wishes forestalls the ascent of the pentacolon, strips away the climactic conclusion, and eradicates any trace of polysyllogistic phrasing which speaks not only to the intended rhythm and progress of jefferson’s authorship, but also to the stylistic age to which he is intrinsically wed. the removal of the anaphorically related “that” at line – which would demarcate the third proposition, for example, – effectively neuters the polysyllogistic sense of purposeful expectation in the original, and in place of the fifth proposition (“whenever any form of government becomes destructive of these ends, it is the right of the people to alter or abolish it”), the commission instead appends the final lines of the declaration, rendering the ascent towards george iii’s tyranny as a nondescript affirmation of general freedom. not only is the jump to the document’s conclusion injurious to the rhetorical intricacy of the preamble, but the alterations made to this new conclusion further detract from another celebrated section of the declaration as a paradigm of jefferson’s writing. assessing the lexical incorruptibility of the declaration’s final sentence, carl becker suggests the words almost have an innate grammatical sanctity: how much weaker if he had written “our fortunes, our lives, and our sacred honour”! or suppose him to have used the word “property” instead of “fortunes”! or suppose him to have omitted “sacred”! consider the effect of omitting any of the words, such as the last two “ours” – “our lives, fortunes, and our sacred honour.” no the sentence can hardly be improved ( ). the commission evidently thought otherwise, consistently privileging the accommodation of roosevelt’s tendentious reclamation of the declaration for his contemporary rhetorical framework of american democracy versus fascist autocracy. by stripping away any specific context-dependent enumerations from the declaration, and showing a disregard for jefferson’s lexical artistry, the commission ensured that jefferson’s voice was spoliated for the modern audience. together, roosevelt and the commission use the founding document to restate the authoritative position of the american superpower at a moment of existential crisis, inhabiting the plural pronoun of the quotation affirming protected liberty, and relying upon the modal and infinitive verb sense of the inscription (“ought to be free and independent states”) to bring jefferson – and his defining document – to an object of perpetuating cultural memory and, potentially, rooseveltian activism. thomas jefferson memorial panel c (tjmpc) if tjmpb is controversial as a result of the commission’s decision to deviate from a source text of national celebrity for contemporary rhetorical application, tjmpc is doubly so because of the sheer number of sources – some famous and some less so - harnessed to furnish a panel of only ninety-seven words. the full scope of the panel’s misleading rhetorical composition is illustrated in appendix c. as a consequence, the inscription upon the northeast interior quadrant wall is potentially the most contentious example of the manipulation of jefferson’s words for the evocation of his public memory. the patch-work panel recontextualizes five separate sources and knits them into a singular expression of jeffersonian liberty, with an emphasis upon god-given freedom, anti-slavery, and general education. though presented as a pure and uninterrupted quotation, without ellipsis, the content is drawn from disparate sources spanning forty-seven years of the author’s life. the panel includes words taken from a political tract, a summary view of the rights of british america ( ); his only full length book, notes on the state of virginia, ( ); his personal narrative, jefferson’s autobiography, ( ); correspondence with his mentor, letter to george wythe (august , ); and an epistle to the first american president, letter to george washington (january , ). through chaining together variously extracted elements of jefferson’s writing and presenting them as the direct product of the memorialised, the commission perpetrates the fallacy of contextomy leading to a false attribution of a complete statement which jefferson never intended to be written in particular, the archival record relating to the selection process of this quotation reveals the tense negotiation of jefferson’s variable reputation relating to the institution of slavery and the abolitionist movement. while it is clear that a number of the commissioners were uncomfortable with a simplified caricature of jefferson’s record, others were more concerned about the comparative effect of such a quotation being memorialised in the age of roosevelt. like jefferson’s, roosevelt’s performance in the arena of civil rights was mixed, especially at the time of the memorial’s conceptualisation. though african americans certainly benefited through the institution of the new deal economic framework and improved labor laws, they were often deliberately excluded from specific programmes and their advantages. roosevelt’s reliance upon the southern white democratic caucus meant that he resisted a comprehensive civil rights agenda and, prior to world war ii, failed to institute anti-lynching legislation. to remember jefferson in the context of slavery was to invite a comparison with the extant racial inequalities under the roosevelt administration. the decision to reduce and embed the reference to abolition in this panel was arguably informed by the perceived imperfection of both men as proponents of african american progress, proving the rhetorical symbiosis of past and present at work. tjmpc- . a summary view of the rights of british america, . “still less let it be proposed that our properties within our own territories shall be taxed or regulated by any power on earth but our own. the god who gave us life gave us liberty at the same time; the hand of force may destroy, but cannot disjoin them” (boyd, : ). the first eight lines of tjmpc are taken from the penultimate sentence of jefferson’s summary view, a political tract “intended for the inspection of the present delegates of the people of virginia now in convention” (i.e. the inaugural continental congress). it is a document expressing both contemporary concerns and jefferson’s political philosophy, forming an embryonic argument for the dislocation of the underlined section indicates the text used in the thomas jefferson memorial panel american colonies from the control of great britain. throughout the summary view, jefferson decries george iii’s authoritarian grip over his native state’s ability to make fundamental fiduciary and political decisions, hampered as it was by the monarch’s “inattention to the necessities of his people.” jefferson levels a series of grievances at the british crown ranging from king george’s response to the boston tea party, to the restrictions placed upon the colonies in effectively dismantling the institution of american slavery. “the abolition of domestic slavery is the great object of desire in those colonies,” jefferson writes, “where it was unhappily introduced in their infant state.” extracted from a complex , -word long treatise on the numerous rights of british virginia, these eight words do not capture the essence of jefferson’s catalogue of political opposition, but are rather deployed in the sense of the beginning of a prayer or supplication to god. it is clear, from examination of the source text, that the quotation creates a new complete and simple sentence out of an elaborate construction, eliminating the initial determiner and impacting the statement’s parallel arrangement. extrication of the preceding sentences, which level attacks on taxation and exclusion from commodity markets, as well as removal of the complementary parallel section of the quoted sentence “the hand of force may destroy, but cannot disjoin them,” essentially neutralises the pointed and contextually-anchored criticism of british policy. jefferson’s concluding and embedded political argument is fundamentally transformed into the simple religious framing for tjmpc. . . . tjmpc- a. notes on the state of virginia, c. - "for in a warm climate, no man will labour for himself who can make another labour for him. this is so true, that of the proprietors of slaves a very small proportion indeed are ever seen to labor. and can the liberties of a nation be thought secure when we have removed their only firm basis, a conviction in the minds of the people that these liberties are the gift of god? that they are not to be violated but with his wrath? indeed i tremble for my country when i reflect that god is just: that his justice cannot sleep for ever" (ford, : ). the proceeding words are derived entirely from jefferson’s influential book-length work, notes on the state of virginia. the text originated in in response to the secretary of the french delegation – francois barbe marbois – who, during his posting in the temporary capital philadelphia, circulated a questionnaire requesting information on each of the thirteen colonies. jefferson was responsible for responding to the questionnaire on behalf of virginia, and it was this transcript which ultimately provided the basis for notes and gave it its overall sense of a directory or chronicle. jefferson’s work is not narrative, but rather a compilation of key state data points regarding rivers, seaports, mountains, population, religion, public revenues, laws, customs, and history. the document remains noteworthy for exposing jefferson’s views on the separation of church and state (fuelling federalist calls of “atheist”) and controversial for what it reveals about his policy on slavery and miscegenation (complicating jefferson’s already entangled relationship with the cause of abolition). this portion of the panel is derived exclusively from the second paragraph of section xviii of notes, on the topic of “manners.” extracted as they are, however, these words form less an objective summary of the attitudes of the virginian people, and more a glimpse into the religious and patriotic psychology of the author. the statement – selected, in part, no doubt, for its lexical continuity with the god-given freedoms of the summary view quotation (demonstrating the deliberate guise of a singular text) – serves as an expression of jefferson’s perceived crisis of national faith, but makes no reference to the main point of jefferson’s original: the injustice of american slavery. though jefferson uses the entire section on “manners” exclusively to address the issue of slavery and its pejorative effect upon virginian behaviour, the excerpted quotation instead presents a self-contained religious responsorial through careful redaction. the removal of the conjunction “and” at the beginning of the statement cuts all grammatical ties to the previous discussion of slave-owner immorality, and thus erases the primary object of jefferson’s religiously stated despair. this particular example of deliberate recontextualization is one of the clearest examples of calculated misrepresentation, but it is also peculiar for suppressing the theme of slavery to which the panel subsequently returns. his proximate criticism of black subjugation is circumvented in this quotation only to be revivified in concentrated form in the subsequent seven words of the panel, taken from the very same section of notes. tjmpc- b. notes on the state of virginia, c. - “the whole commerce between master and slave is a perpetual exercise of the most boisterous passions, the most unremitting despotism on the one part, and degrading submissions on the other. our children see this, and learn to imitate it...” (ford, : ). where the first quotation from notes’ section on manners evades reference to jefferson’s argument for abolition, these seven words state it with the force of a paternal and moral categorical imperative. distorting the order of the original, this quotation reverts to the first paragraph of the section and, without any formal ellipses, pretends to be a statement of climactic subsequence. the words are recontextualized from a complex grammatical composition, stripping back the ornate jeffersonian vocabulary and undoing the rhetorical balance of the final phrases. the “unremitting despotism” of the masters, for example, is associated syntactically, visually, semantically and rhythmically with “degrading submissions” of the slave community. the erasure of the latter part of that parallel construction removes the equalizing emphasis upon the condition of the subjugated. the quotation as extracted presents jefferson’s attitude toward slavery as one of unremitting, indignant opposition to an institutional despotism. however, the recontextualization oversimplifies and attempts to ameliorate jefferson’s historical position in the cause of abolition. whilst jefferson briefly decries the institution of slavery in the section on “manners” in notes, he does so less as a moral necessity and more in racist reaction to its observed “unhappy influence” upon virginian behaviour. “the man must be a prodigy,” jefferson remarks, “who can retain his manners and morals undepraved by such circumstances” (ford, : ). jefferson’s stated outrage is couched within an a posteriori argument informed by a moral relativist observation, re-worked by the commission to feature as a bellowing a priori objective morality. the act of contextomy enforces an unequivocal certainty that denies the less forward-thinking elements of jefferson’s ruminations on slavery in the same source text. in section xiv of notes on “laws,” for example, jefferson devotes a significant portion of his survey to the potential consequences of post-emancipation america. with the detachment of a prejudice-laden anthropologist, jefferson sees “deep rooted prejudices entertained by the whites; ten thousand recollections, by the blacks, of the injuries they have sustained; new provocations; the real distinctions which nature has made; and many other circumstances,” which threaten to “divide us into parties, and produce convulsions which will probably never end but in the extermination of the one or the other race.” racial integration is made problematic because of the irreconcilability of the “physical and moral” differences represented by colour, which is “the foundation of a greater or less share of beauty in the two races.” whites have “flowing hair, a more elegant symmetry of form” – so fair that even the black man shows “judgment in favour of the whites…as uniformly as is the preference of the oranootan for the black women over those of his own species.” blacks have, according to jefferson, “less hair on the face and body” and “secrete less by the kidnies, and more by the glands of the skin which gives them a very strong and disagreeable odour.” jefferson proposes that black people have the potential to love, but that “love seems with them to be more an eager desire than a tender delicate mixture of sentiment and sensation.” he promulgates that blacks feel less pain and discomfort (“those numberless afflictions…are less felt, and sooner forgotten with them”); they are musically gifted but whether they are “equal to the composition of a more extensive run of melody, or of complicated harmony, is yet to be proved”); “their disposition is to sleep;” and “in memory they are equal to the whites; in reason much inferior…in imagination they are dull tasteless and anomalous.” jefferson concludes, with the caveat that his ideation is more “a suspicion only,” that the black people “whether originally a distinct race, or made distinct by time and circumstances, are inferior to the whites in the endowments both of body and mind” (ford v. ). reconciling this self-revealed character of jefferson with the author of the very same work that argues passionately for the future emancipation of slaves, remains a point of academic disputation, befuddlement and evasion. whilst it is clear that one can find a race inferior and still advocate for the fair treatment of its members, the sphinx-like (ellis ) historical persona of jefferson – on this issue in particular – oscillates between a visionary of freedom (e.g. peterson , ferling , malone ) and a man anchored to the racisms and practices of his age (e.g. wiencek , finkleman ). through this quotation the commission attempts to clarify this interpretative confusion by capturing a single snapshot of jefferson’s oscillation, but in doing so they memorialise a caricatured and ameliorated political position, resolving the difficult and debated subject of jefferson’s reputation on slavery, and excising the quite significant prejudicial overtones of jefferson’s work tjmpc- . jefferson’s autobiography, "nothing is more certainly written in the book of fate than that these people are to be free. nor is it less certain that the two races, equally free, cannot live in the same government. nature, habit, opinion has drawn indelible lines of distinction between them" (boyd, : ). the commission’s attempts to navigate jefferson’s contradictions on the issue of slavery are also evident in the extraction of the above eighteen words from jefferson’s autobiography, which elaborate and sustain the memorial’s interpretation of the third president as a prophetic trailblazer in the march towards emancipation. jefferson’s work is not a traditional autobiography, but rather a concise summary of notable life works – a form of self-memorialisation. this quotation is taken from the middle section of the text, as jefferson surveys the major legislation of the late s, and specifically a “bill on the subject of slaves,” which he describes as “a mere digest of the existing laws respecting them, without any intimation of a plan for a future of general emancipation.” the law avoids explicit reference to the manumission of slaves, jefferson explains, “as the public mind would not bear the proposition…yet the day is not distant when it must bear and adopt it.” the quoted words, however, do not convey any of jefferson’s equivocation or contextualisation surrounding the proposed policy of emancipation. the unconditional tone (“nothing is more certainly written”), absolute concepts (“to be free”), as well as the semantic of inevitability (“book of fate”) renders jefferson’s phrase – in isolation – as a trumpet call for social action, and it is this clarion voice that the commission extracts and adopts to speak from the walls of their eventual memorial. these quoted lines eradicate the dissoi logoi of the statement’s original context. like notes on the state of virginia, jefferson’s autobiography is a receptacle for jefferson’s expressed contradictions on the matter of manumission – principled in argument, but cautious in practicality. the antithetical sentiments in the autobiography, moreover, are so proximate to the quoted statement (as exemplified above) that their extraction is at best misguided and, at worst, purposefully misleading. the quotation deliberately mutes jefferson’s indulgence in the racist terminology of his age, and distils his legacy on emancipation into one of seeming chapter-closing – and positive – singularity. tjmpc- . letter to george wythe, august , "preach, my dear sir, a crusade against ignorance; establish & improve the law for educating the common people." tjmpc- . letter to george washington, january , "it is an axiom in my mind that our liberty can never be safe but in the hands of the people themselves, and that too of the people with a certain degree of instruction. this it is the business of the state to effect, and on a general plan." the final twenty-three words of tjmpc are taken from two letters authored by jefferson in , whilst he was the us minister to france: one written to george wythe (his former law professor at the college of william and mary), and the other written to george washington (before he assumed the presidency), each representing distinct epistolary contexts. without formal ellipsis, the produced quotation is a pretended continuous, contemporaneous statement on universal educational provision as the addendum to a panel that refers to a diverse range of political positions. the imperative phrase extracted from the wythe letter for the institution of public education is found at the conclusion of the correspondence in which jefferson identifies the establishment of a new political republic as an opportunity for implementing improved education, redirecting public monies that had traditionally supported nobles, priests and kings. jefferson advocates an american (and specifically anti-european) educational brand, explaining to wythe that “i think by far the most important bill in our whole code is that for the diffusion of knowledge among the people.” grammatically, the quotation excises the sentence’s opening and, without ellipsis, also removes the second verb (“improve”) and with it jefferson’s belief in the continuous evolution required at the heart of a first class system of education. the quotation taken from the letter to washington re-emphasizes the preceding words of the inscription by underlining public education as explicit state business. there is no internal damage done to the syntax or balance of the sentence, though the detail of the contemporary debate around jefferson’s proposals is suppressed in the recontextualization. if the quotation suggests legislative certainty, jefferson’s letter acknowledges the multiplicity of educational proposals under consideration, including the use of charity schools as proposed by his addressee. the quotation also strips away jefferson’s belief in public education as a means to effect social change by passing the baton of democratic leadership to the common populace: “[l]iberty can never be safe,” he writes, “but in the hands of the people themselves, and that too of the people with a certain degree of instruction.” what is retained, if not exaggerated, is the sense of jefferson’s pro-governmental position, that the state has a the letter to wythe (written in august) postdates the letter to washington (written in january) further demonstrating the commission’s acceptance of distorted textual chronology. positive and transformational role and interest in promoting social mobility – particularly among the political elite. through the amalgamation of two private letters, the commission created an aphoristic proclamation on educational reform that jefferson would not recognise as his own. the commission expanded jefferson’s musings into a statement that endorses universal public education – a policy that jefferson never strictly recommended, but that comported with the pedagogical focus of roosevelt’s new deal, and, for example, his federal appropriations for national school relief following the impact of the great depression. as richard hamowy pointed out in his review of jeffersonian reclamation, “jefferson’s admonition that an educated electorate was essential if liberty were to be preserved is transmuted into a call for universal public education.” in totality, tjmpc represents a memorial panel designed by committee, culminating in false quotation born of the contestation of commission egos, historical (re)interpretations, theories of epigraphical memorialisation, and a variety of motivational forces at play over its years-long formation. the breadth of this compromise is demonstrated by the range of topics covered in the tapestried quotation, spasmodically transitioning from the nature of human creation, to theological justice, to slavery, and to universal education, giving the sense of aphoristic compilation. the leaflet produced by the commission to attend the official opening of the memorial in , described the formation of tjmpc as a deliberative process whereby quotations were carefully researched and selected to resound with established interpretations of the cornerstones of jeffersonian philosophy, “to his concepts of freedom of the body and to his beliefs in the necessity of educating the masses of the people” (tjmc- ). this presentation of a clean and undisputed exercise of quotation-as-value-memorialization, however, belies the ideological conflict and compromise at the heart of this tangled rhetorical construction of memory – over the meaning of the four freedoms, over the appropriateness (and rooseveltian relevance) of slavery as a memorialised subject, and over jefferson’s role in the history of emancipation. kean first introduced his argument for a panel exclusively devoted to slavery in a letter to senator thomas on october , . kean identified “freedom of the slaves” as one of jefferson’s core philosophical freedoms, and justified its commemoration in the memorial as a means to revive the issue in the public’s imagination. in his attempts to write the pro-abolitionist jefferson into the book of national consciousness, kean called upon british liberal historian francis hirst and his life of jefferson, in which jefferson is described as “the only powerful statesman of his day in america who was willing to risk political future and social favour in an active effort to remove this dark blot from the institutions of this native land” (tjmc- october , ). employing a somewhat positive interpretation of jefferson’s anti-slavery legacy, kean defended the memorialised, writing that whilst “he was unable to get the law which he and chancellor george wythe had prepared for the gradual abolition of slavery to be passed by the virginia legislature, he did succeed in getting acts forbidding the slave trade passed both by the virginia legislature in and by congress in .” kean not only presented an academic case to thomas at this early juncture, but also appended three separate proofs setting out the alternatives for a panel on slavery. these suggestions, included as appendix d, positioned jefferson as a pioneering abolitionist in three different forms to maximise the agreeability of the proposal for the onward approval of the diverse commission membership. at the subsequent meeting of the commission on january , , two of the most significant members – chairman gibboney and senator thomas – initially favoured kean’s recommendation of a panel devoted to the subject of emancipation whilst kimball sought a less overt reference. kean was emphatic that the subject of slavery deserved a panel to itself: “it does not seem to have been brought out by american historians and seems to be little known or appreciated by the general public today,” kean implored, “yet it had a large influence on our national life” (january , ). as dawned, however, a panel on slavery faced renewed challenge from a large constituency of the commission – including the once-supportive chairman, stuart gibboney. this mood change intersected with, and was perhaps precipitated by, a sharp increase in roosevelt’s direct interest in the progress of the memorial’s inscriptions. on th december , roosevelt asked the librarian of congress, archibald macleish, to compile a series of quotations for potential inclusion in the memorial’s quadrants. macleish provided a series of textual testimonies to jefferson’s achievements, covering a diverse range of topics including the constitution, education, free speech, liberty, political economy, agriculture and democracy. roosevelt forwarded his dossier to the commission with the explicit endorsement of the presidential seal. crucially, macleish’s suggestions made no reference to the issue of slavery, implicitly rejecting the nearing consensus of the inscription committee’s panel on jefferson’s role in american emancipation. the president’s interjection drove an ideological schism in the process. simultaneously, the chairman made his telling u-turn, rejecting the entire notion of the four freedoms as a vehicle for the memorial’s rhetoricity. in place of the slavery- themed drafts under consideration, gibboney suggested an entirely new source and thematic focus based upon a letter from jefferson to samuel kercheval on constitutional adaptability. a number of arguments emerged from the commission in resistance to a panel that raised the controversy of jefferson’s position on slavery. gibboney and ryan were concerned about complicating the legacies of jefferson and lincoln. tumulty was wary that the panel might be interpreted as an attempt “to rouse resentment” in the post-emancipation era, asking, “are we not opening up the old sores?” (tjmc- february , ). dr kimball said that whilst he could not hear kean’s suggestion “without feeling a tingling up my spine,” the sentiment seemed to be captured in the equality clause of the declaration: “i would not want to see slavery neglected but i feel it is there as part of civil liberty.” mr culkin believed the “slavery proposition would be a mistake.” the chairman agreed, stating that “i think some members of the commission thought it would be somewhat like waving a bloody shirt.” the archive is littered with such statements of resistance to a panel addressing slavery on the basis that such a topic was politically inauspicious and electorally inert in the age of roosevelt. the compromises of this particular panel exemplify the discrete indulgence of two competing forces of contemporary parallelism and historical (re)interpretation. the compromised draft for tjmpc was brought to the final full commission meeting on september , , at which the inscriptions were debated. despite the dilution of the slavery issue within a panel that now expressed a more general sentiment on human liberty, even this weaker concentration on the subject was under threat. senator andrews objected to many of the quotations selected, including one relating to the commerce between master and slave. “i think it should be left out. it means nothing to anybody. it is not impressive and i would rather not hear about it.” exposing the anti-historical ethos of some commission members, andrews lamented any reference to slavery in tjmpc as contrary to modernity (and the rhetorical agenda of the commission) because it did not speak to government “as it exists now.” kean replied: this makes it all the more obligatory for the commissioners charged with the duty of bringing to the knowledge of future generations his great words and deeds to point the finger of history at this particular panel…i for one would feel that i had failed in the duty placed upon me by the president if i should be a party to any conspiracy of silence with regard to it (tjmc- ). the revised panel with reference to slavery (appendix e) was eventually put to a vote, leading to a dramatic tie. chairman gibboney – who had consistently objected to an inscription on the subject – was the unexpected redeemer of kean’s compromised panel, endorsing it for architectural submission on october , . the fractious deliberations surrounding tjmpc, and the unsatisfactorily constructed nature of the panel itself, supplies evidence for the rhetorical argument of this thesis. unlike expressions of generalized liberty, democracy-over-autocracy, progressive government or religious tolerance, the specific issue of slavery was not only complicated by jefferson’s biography, but also contested by the commission because of its lack of relevance to the america of roosevelt’s inheritance. slavery, as an institution, had been abolished and was no longer a cause for political reclamation. furthermore, a recontextualized quotation of racial freedom from the eighteenth century risked inviting comparison with roosevelt’s own record as an advocate of african american rights. while roosevelt’s numerous relief efforts benefitted many black americans – and eleanor roosevelt gained a reputation as an outspoken defender of racial equality – jim crow policies of de jure segregation persisted throughout the s. furthermore, a number of the new deal initiatives, such as the fair labor standards act ( ), which protected wages and hours, and the national labor relations act, which protected employee rights and unionization, specifically excluded the majority black professions of domestic service and farm labor, as appeasement to roosevelt’s southern democratic allies. the archives reveal that the rhetorical agents of jefferson’s memorial were sensitive to the inclusion of an inscription referencing slavery during roosevelt’s administration, with commission members describing the panel as a “bloody shirt” that would “arouse resentment” and open “old sores.” a statement on slavery provided no opportune tendentious parallel between the founding father and the ethic of roosevelt’s programme, and lacked the broader international resonance offered by other panels. as a consequence, tjmpc is a panel of tangled motivations which ultimately suppresses the complexity and sometimes ugliness of jefferson’s (and by rhetorical extension, roosevelt’s) racial politics, and edits jefferson’s own writings to perform as a mouthpiece for federal educational intervention. thomas jefferson memorial panel d (tjmpd) the engraving on the panel of the southeast interior wall (hereafter tjmpd) is derived entirely from jefferson’s letter to samuel kercheval on june , . the selected quotation advocates intellectual advancement and implores institutional and legal adaptability – a proposition that might be read as the foundational statement of progressivism itself. this is achieved through the compilation of various proximate phrases and sentences from the letter’s penultimate paragraph (without ellipses). the original tone of self-reflection is excised and much of the first person pronoun is suppressed in order to extend jefferson’s individual musings to the level of a national, and reclaimable, pronouncement or recommendation. according to richard hamowy, the result is a very un-jeffersonian “justification for a new theory of government in keeping with the social-democratic principles that animated the new deal.” the leaflet prepared for the memorial’s dedication corroborated that intent, claiming, “jefferson’s vision in matters of government is demonstrated by the fourth panel. by this statement which appeared in a letter to a friend, we know that he recognised the necessity for change in the laws and institutions of a democracy as opinions altered, new discoveries were made, and circumstances changed” (tjmc- ) the memorial aligns this philosophy with the sentiment and practice of roosevelt’s paradigmatic shift in legal, societal and economic affairs, under the broad umbrella of the new deal. following the exhaustive debates and compromise over tjmpc, the kercheval letter (which had not yet been considered seriously for any of the memorial’s quadrants) gained the admiration of lanham, culkin and other commission members who successfully moved to substitute all other source texts for tjmpd with the chairman’s proposal (may , ). jefferson was responding to kercheval’s request for his perspective on the nature of equal representation within the united states. having extensively outlined the inequalities of representation in the congress, senate, executive and judiciary, jefferson promoted a number of advisory steps to improve the administration of government, including general suffrage, equal representation in the legislature, ward divisions and – importantly – periodical amendments of the constitution. the lexicon marshalled by the tjmpd inscription (change, progress, new discoveries, new truths, enlightened, advance, pace) is a relatively faithful concentration of the original’s call for generational governmental pragmatism, albeit extracted from a private epistolary context that jefferson insisted upon remaining so. jefferson could have little imagined that such a source might be recontextualized to form an entire quadrant of his public memorialisation, nor that it might one day be understood as a partially activist justification for the institutional transformations associated with the post- second new deal, which systemized the structural reforms of the era. once more, jefferson’s historical remembrance through this inscription seems intertwined with a parallel process of ventriloquization in a discrete political context of modernity that relies upon the historical object’s temporal translucence. thomas jefferson memorial panel e (tjmpe) the engraving on the panel of the northwest interior wall (hereafter tjmpe) is compiled from an excerpt from “the virginia statute for religious freedom” (drafted , enacted ) and a statement taken from a letter to james madison, dated august , . the highly selective quotation includes a pronouncement on the freedom of religious thought with an addendum on universal morality. freedom of religion was one of the so-called four freedoms of jefferson’s political thought, which came to be embraced and reinvigorated by roosevelt’s own rhetorical repertoire. in his state of the union address, roosevelt modernized jefferson’s four freedoms as a framework for his speech on the threat posed to american national security and democracy everywhere by world war ii. in roosevelt’s version, freedom of religion becomes the freedom of worship, with a particularly international emphasis: “the second [of the four freedoms] is freedom of every person to worship god in his own way – everywhere in the world.” passed by the virginia general assembly in january , jefferson’s statute disestablished the church of england as the preferred state religion, paving the way for the constitutionally enshrined right to religious liberty and intellectual freedom of the first amendment. the recontextualization of the statute involves the selective quotation from the preamble and the conclusion, eradicating any evidence that the source text was – in tone and structure – a legislative document. the panel utilises only one of the statute’s many premises, delimiting the compound sense and rhetorical dependency of the original. jefferson’s embedded clauses, and more florid language from the preface, are recontextualized to create a significantly more dogmatic text than the original. the inscription also eradicates the centre of jefferson’s ascending tricolon, forestalling its full effect whilst, unlike the earlier quotation, presenting no ellipses to indicate the manipulation by the commission. the final sentence of tjmpe is appended from a substantial letter from jefferson to james madison (august , ) in which the author gives credence to the notion of objective morality. the statement, however, is derived from a personal epistolary context, resulting in the panel’s inelegant transition from the identity-neutral language of the virginian statute to personal revelation. the compound quotation also suffers from a very un-jeffersonian thematic leap from a paragraph on religious freedom to a dogmatic affidavit on universal singular and collective morality. two primary suggestions for a panel expressing the freedom of religion (one of jefferson’s four freedoms) were considered throughout the memorial’s construction. kean’s initial proposal (appendix f) was a quotation taken entirely from the concluding section of the statute (the preamble would be added later), whilst senator thomas’ proposal (appendix g) was yet another composite quotation, referencing constitutional change, the populace’s responsibility for liberty, freedom of religion and morality. thomas relied upon the statute for the central component of this inscription, before concluding with a sentence on morality extracted from jefferson’s letter to james madison. over the next year, kean’s panel was broadly favoured, and at the meeting of the commission in february , his proposal included a section from the statute’s preface on the recommendation of dr kimball. the chairman described the source text as “one of the finest bits of language in the world” prior to the panel’s unchallenged endorsement. thomas highlighted that this decision resulted in the loss of his final quotation from the madison letter on morality, leading to members smith and lanham proposing that they be retained and incorporated within kean’s scheme. this motion to amalgamate the wording was seconded and carried, yet kean questioned the resultant integrity of the overall quotation, stating “that will introduce a thing that is not in the preamble or the law.” kimball responded that “we are satisfied in doing that” because “i do not think the statute on religious freedom is so well memorized by the public as a whole that they will know whether or not it is extraneous.” this stunning admission revealed by the tjmc archives, provides an important insight into the commission’s optioneering process, demonstrating not only an irreverent attitude toward the state of the public intellect, but also an explicit awareness of the rhetorical manipulation of memory, exacted without the fear of public consequence or challenge. the eventual panel met the intent to memorialise one of jefferson’s central four freedoms, and to remember that “[h]e had already, in virginia, separated the church from the state, guaranteeing freedom of religion” (tjmc- april , ). the quotation not only refers to the legacy of jefferson’s ideal of free religious thought (a luxury not afforded to jefferson during the contentious theological debates surrounding his own candidacy) but also reflects his reticence to discuss personal faith within public discourse. the inscription also functions rhetorically, however, to echo the rooseveltian connection between religious freedom and american democracy: the lessons of religious toleration - a toleration which recognizes complete liberty of human thought, liberty of conscience - is one which, by precept and example, must be inculcated in the hearts and minds of all americans if the institutions of our democracy are to be maintained and perpetuated. there can be no true national life in our democracy unless we give unqualified recognition to freedom of religious worship and freedom of education (march , ). the tjmpe inscription was undoubtedly selected because of its resonance with an era that feared the twinned rise of fascist ideology and religious intolerance, symbolized by the nazi-led genocide of europe’s jewish population. jefferson’s statute had disestablished the church of england in order that all protestant congregations, catholics and jews could enjoy the practice of faith without incrimination. a century and a half later, jefferson’s principle of the wall of separation between church and state was re-inscribed to strengthen a culture that was witnessing the nightmare consequence of abandoning that principle. chapter : the rhetors – the tjmc and fdr as inventors of public memory deriving the motive forces that compel the creation of a single memorial is, at first glance, as idiosyncratic and qualitative a process as defining the impulses driving the pen of a particular novel, the provocation of a brushstroke, the intent of a chisel. as adam gopnik ( ) has recently complained, for example, the interpretation of a memorial’s motive(s) is so often complicated by a “broadly unsatisfactory language of commemoration,” which – in isolation – can be “confusingly laconic in its architectural grammar.” unlike the private consolation of imagination or the internalised motives of the individual artist, however, the creation of a national memorial is an act of rhetorical communality, leaving behind a partial record of the interaction and competition of motives among the various agents, agencies, scenes and purposes working upon those entrusted with its execution. the memorial therefore, understood as a legitimate rhetorical product, text or act, has the advantage of some form of motivational testimony, against which the a posteriori interrogation of the historical object’s mediation (understood through kenneth burke’s pentad and sturken’s technologies of memory, for example) can be conducted with a rare measure of evidentiary support. consequently, the scope of this thesis’ analysis is indebted to a decision taken in by the executors of the commission chairman stuart gibboney’s estate “to see that all the papers relating to the conduct of the affairs of the commission should be put away safely and kept for a reasonable length of time” (tjmc- july , ). almost seventy years later, this archive reveals the significant multivariate motive forces upon the selection and manipulation of the memorial’s inner chamber inscriptions, as well as jefferson’s overall re- situatedness at the hands of the commission. this chapter focuses upon two essential motivational currents at work, as a brief (and by no means comprehensive) illustration of the evidence available to examine the praxis of jefferson’s individuated commemoration in s america. first, the commission archives uncover the competing intentions at work to remember (and forget) aspects of the historical person of jefferson (section . ), to establish in stone and brass his pre- eminence as an american and democratic hero, and to assert his place amongst the capital’s main geographical memory complex, alongside lincoln and washington. the archive reveals the entanglement of the commission members’ various mythologies and personal interpretations of jefferson’s historical character, as well as competing theories of public commemoration. second, the archives demonstrate the extent to which the commemoration of jefferson was summoned as a witness of the progressive agenda of roosevelt and his new deal (see section . ). as the primary agent of the memorial’s creation, roosevelt exerted and maintained a level of interpretative influence throughout the commission’s existence, in order to force or emphasise the compatibility of the monument’s rhetoric with his own. by appropriating the words of jefferson – and using the (overwhelmingly democratic) commission as his agency – roosevelt ventriloquized the memorial for maximum personal effect in his th century political context, historicizing his own legacy, whilst also distilling jefferson’s for modernity. the thomas jefferson memorial commission: jefferson (un) remembered the thomas jefferson memorial commission comprised multiple and often competing agents of rhetorical formation, shaping the commemorative object and its inscription content, through a complex and years-long negotiation of ego, differing historical interpretations, various reclamations of jefferson for tendentious applications, and alternate theories of acceptable levels of quotation fidelity. at the time of its appointment, the commission consisted of the following membership: rhoads ( ) has identified roosevelt’s “deep and direct” involvement with governmental commissions. appointed by the speaker of the house hon. john j. boylan hon. howard w. smith hon. francis d. culkin appointed by jefferson memorial foundation mr stuart gibboney dr fiske kimball dr george ryan appointed by president hon. thomas jefferson coolidge hon. joseph p. tumulty mr hollins s. randolph appointed by vice president hon. elbert d. thomas, utah. hon. augustine lonergan, conn. hon. charles l. mcnary, ore. despite the multiplicity of agents and attendant motives, all members were broadly aligned to the memorial’s overall purpose to commemorate jefferson as a representative of american liberty and constitutional democracy. “the worthy concept represented in this memorial,” explained louis ludlow in the house of representatives, is to embody “in visual form a nation’s love for the man who, above all others, created the ideals of popular government in the western hemisphere” (tjmc- june ). more specifically, the commission considered the four internal memorial panels upon which the inscriptions would be laid as potential sites for immortalising the specific concept of the so-called “four freedoms” of jefferson’s making and legacy. this concept – written into the very quadrant design of the memorial’s interior – was embedded within the initial programme of competition for the construction of the pantheon-style monument to jefferson: his fundamental achievement was in the apostleship of the “four freedoms” of america: abolition of feudal tenure of land – freeing the earth; abolition of human slavery – freeing the body; establishment of universal education and freedom of speech – freeing the mind; establishment of religious liberty – freeing the soul. all are summed up in his words: “i have sworn on the altar of god eternal hostility to every form of tyranny over the mind of man” (tjmc- ). this interpretative framework, which influenced the textual selection process (until its abandonment midway through), is doubly problematic because of its post-jeffersonian formulation. the concept of the four freedoms is an act of secondary historical interpretation, made tertiary by the commission’s later subjective application of it as the interpretative framework for commemorative inscription selection. while recommending the four freedoms as a thematic structure, kimball noted: jefferson himself did not formulate the four freedoms…although they are all mentioned in the course of his first inaugural and in many other places. the formulation which i followed was made by dr alderman, president of the university of virginia….he based it on a series of bills offered by jefferson in the virginia legislature, proposing reforms which were afterwards incorporated also in the work of the revisors of the virginia laws. (tjmc- oct , ). alderman’s interpretation of jefferson’s legacy, bound the members of the sub-committee on inscriptions to manipulate jefferson’s words into this contemporary quarto. kean recorded that “i have written out proposed inscriptions for four freedoms which comply with these very narrow limitations” (oct , ), and thomas “worked rather hard trying to make four suitable quotations limiting the panels to something equivalent to what we might call jefferson’s four freedoms” (tjmc- dec , ). so firmly were the four freedoms revived as an american conceptual framework that president roosevelt made it the rhetorical theme and structure of his annual message to congress on the state of the union in . senator thomas, who during his commission tenure was writing a full-length book on jefferson, thomas jefferson: world citizen ( ), approached the task of quotation selection with an unparalleled expansionist attitude. restricted as he was by the thematic quartet and the legibility of the brass letters, thomas struggled with the task of condensing the character of jefferson from his full- length volume into the short paragraphs of his remembrance. whereas kean and gibboney developed panels in thematic isolation, using one panel for one thought or “freedom,” thomas prepared a single prosaic statement that was subsequently divided into four length-appropriate sections. as a result, thomas’ panel drafts, parts of which were adopted, were less about remembering jefferson through textual fidelity, and more about amassing and re-contextualising dozens of jeffersonian quotations in an acrobatic display of topical erudition. thomas explained: jefferson did not write an inscriptive language . . . i wondered if we could not take jefferson’s words and adhere entirely to jefferson’s words and get a small, complete statement of jefferson . . . by starting the process of arrangement, leaving out the elements of time, and then just by eliminating all of the unnecessary words. i began to count the various american political concepts that were represented in this simple little statement and i counted something like forty-eight (tjmc- february , ). thomas’ approach is one of simultaneous rhetorical creation and destruction – dependent on a cavalier approach to the textual integrity of jefferson’s original, the collocation of his statements, and the chronology of ideas – in order to provide a densely concentrated version of almost individual political concepts. thomas’ concentration (and “elimination”) of the source texts in fact dilutes an accurate memorialisation of jefferson’s words, sacrificing quality for quantity. that thomas was the chair of the sub-committee on inscriptions speaks to the mechanism of the textual misremembering and tonal misrepresentation of jefferson through his own language. in commemorating jefferson conceptually (and anti-textually) this way, thomas also enacts a form of modern reparation, inducing the reader to (invisibly) forget the distinct source, style and context of jefferson’s original, in favour of a streamlined version. justifying his approach, thomas cited the grammatical weaknesses of the third president’s corpus: if jefferson had been writing the panels he would not have had great difficulty…his most choice sayings and most significant sentences sometimes are found in long paragraphs with dangling, incomplete and almost colloquial wording…i have taken sentences and eliminated unnecessary words and i have put sentences out of their original order in respect to time, place and circumstance. no violence is done to jefferson’s thought and no violence is done to jefferson’s expression and i am sure no violence can be done in the interpretation of jefferson (tjmc- dec , ). thomas’ modern reclamation of jefferson as a philosopher of succinctness and concision, necessitated the rhetorical annihilation of jefferson’s voice for the memorial’s recipient culture(s). the opinion that no injury had been done to jefferson as a result of thomas’ method was challenged even by his contemporaries. judge smith worried that “it is entirely possible that by taking three or four sentences from four or five different things and putting them all in one place that you may get a document that jefferson never thought about” (tjmc- may ). kimball also feared that thomas’ approach “may make jefferson sound more dogmatic, because when you shorten the sentence by eliminating words it is more acrostic,” with the potential consequence that “the sentences are not recognised,” or that his historical character is not rhetorically legible. arguably, thomas set the precedent for the commission’s well-evidenced lack of textual fidelity throughout the memorial’s inscription selection process. if thomas influenced the method or philosophy of quotation, kean’s singular attempt to reclaim jefferson as a hero of the african american community demonstrated the subjectivity of the third president’s remembrance within the scene of s america – as well as the individual motives of commissioners at work to objectively define jefferson’s mercurial historical character for a discrete purpose. whilst “freedom of the body” had been accepted by the commission as a facet of the memory-framework of the memorial, the explicit commemoration of jefferson’s work associated with the abolition of slavery was not well agreed upon. kean was, however, a direct descendent of jefferson and consistently urgent in the need to parallel him with the great emancipator, abraham lincoln: when jefferson wrote his sentiments and prophecy with regard to slavery in his contemporaries, far from sharing them, were not concerning themselves at all about the matter...they expunged from the declaration the paragraphs referring to the slave trade which jefferson had written in his draft. likewise the framers of the constitution inserted into it a proviso forbidding congress to interfere with the slave trade for years. jefferson was president when this period expired and sent a message to congress asking for its abolition. in he signed with joy the law which drive this infamous traffic from the seas. (tjmc- september , ). the scene upon which kean wished to exact this rhetorical memory, however, was still the america and washington of jim crow, of segregation, of racial inequality and political exclusion. in essence, the freedom of the (american) body was not an enacted concept at the time of the memorial’s conceptualisation or unveiling, and to include jefferson’s (disputed) work to improve the future of african americans was a troubling prospect for other rhetor-agents of the commission. mr culkin thought “the slavery proposition would be a mistake” (may , ), whilst fellow northerner, mr tumulty objected to a large-scale record of anti-slavery work within the inscription content: i think it will look as if we were attempting to arouse resentment, and why go back to and dig out these ghosts of the past except for a noble reason? my people were on the northern side, but i just think it is going back to a past that we ought to try to forget, and people are so sensitive when they look at those things. it just arouses that old feeling again. (feb , ). senator andrews’ speech against the use of the phrase “created equal,” from the declaration, also laid bare the commission’s unease with referring to anti-slavery in the racial milieu of roosevelt’s era (tjmc- september , ). the objections to kean’s slavery panel – as discussed in chapter – resulted in the suppression of emancipation as a secondary theme within a broader series of quotations regarding human liberty. the result is an entanglement of remembrance and amnesia relating to jefferson’s contribution to civil liberties. as petrina dacres has written on the subject of representing slavery and emancipation within heterogeneous societies, “[i]n the public-historical sphere visual arts and monuments are important to the evocation and denial of memory, a nexus of reclamation and invention significant to the making of history and identity” ( ). the complicated racial scene of roosevelt’s era, the all-white status of the memorial commission, the mixed evocations and denials of the various rhetors, the non-existence of true bodily freedom, and the contemporary memory of jim crow evils, together led to the obscuration and revelation of existing social fissures that we find in the compromised panel on slavery, and within the pages of the commission archives. in the following section, i further assess the extent to which the archives reveal that roosevelt himself effected the advantageous parallelisation of jefferson with the contemporary political scene of s america. franklin delano roosevelt: a th century jefferson roosevelt established his primary agency in the memorial’s creation at an early stage, with the commission of fine arts receiving a memorandum from him in seeking legislative support to erect a memorial to jefferson in washington d.c. (tjmc- may ). soon after the president’s intervention, the thomas jefferson memorial commission was established by an act of congress to direct the erection of a memorial to the third president of the united states. reflecting the roosevelt landslide of , the commission was populated with a majority of democratic representatives – rhetorical sub-agents of political allegiance. the commission consisted of members, three of whom were appointed each by the president, the speaker of the house of representatives, the vice president, and the president of the thomas jefferson memorial foundation. at the time of the commission’s appointment, only two of the commission members – charles l. mcnary and francis d. culkin – were identified republicans. the sub-committee on inscriptions, established on october , , consisted entirely of democratic representatives (gibboney, thomas, and kean). indeed, there were as many republicans on the commission as there were direct descendants of thomas jefferson himself. if almost omnipotent, roosevelt was also an omnipresent agent in forming the rhetorical object of memory and its inscription content. as early as the first recorded meeting of the commission in june , then-chairman john boylan underscored the commission’s fiduciary dependency upon presidential endorsement, stating, “i had in mind that we would not want to do anything positively without consulting the president because he has to help us out with the appropriation and we would not want to run counter to him.” the financial necessity of securing the funds to complete the memorial additionally, the director of the national park service acted as executive agent for the commission. arguably laid the precedent for the commission’s close consultation with the white house and their accommodation of the administration’s preferences. yet roosevelt’s influence went far beyond the issue of economic dependency. throughout the often controversial conceptualization and construction of the memorial, roosevelt’s interventions punctuated key decision points, provided advice, instruction, media cover, self-promotion, and, at times, pointed aesthetic judgement. as the prime mover of the jefferson memorial project, roosevelt received all plans and sketches of the memorial’s progress at the white house in march (tjmc- , february , ), commissioned the re- competition of the monument’s architectural design, privately studied the presented alternatives, endorsed the pantheon scheme (despite disagreements within the commission), and requested the appropriation of $ , from the bureau of the budget to initiate the project. roosevelt interrupted the open competition for jefferson’s statue by reporting to gibboney, “i do not like any of them!” (tjmc- january , ) and urging the committee to “reject them all.” while appealing to gibboney to run a new statue competition, roosevelt was reticent to publicise the evident capacity of his agency upon the rhetorical formation of the jefferson memorial: “under no circumstances,” he wrote, “should it leak out that i have had anything to do with the choice or non-choice of a statue.” roosevelt did, however, publicly rebut criticisms of the memorial’s design and location, and demonstrated singular disregard for the “embattled clubwomen of washington d.c.” whom threatened to chain themselves to site’s japanese cherry blossom trees in order to thwart the construction work. “if they chained themselves,” roosevelt warned, “they would be removed along with the trees” (tjmc- , november , ). roosevelt’s interventions can be understood as attempts to fuse the memorialised with the memorialiser, and to maximise opportunities to parallel of the era of jefferson’s existence and the scene of his th century commemoration. in this sense, the archives provide evidence of the deployment of political commemoration to bolster the legacy of both the manifest object and the sponsoring agent of the cherry tree controversy, and its rhetorical implications for the tjm, is explored on pages - below. its invention. primarily, roosevelt and the committee understood the memorial as having the broad capacity to translate jefferson’s symbolic properties of liberty, independence, democracy, progressivism, and american-ness, into a metonymic rejoinder from the current roosevelt administration towards the growing threat of nazism and fascism in europe. consequently, the memorial becomes an object of rhetorical and temporal duality, performing both as a long-term memory space for the national consideration of jefferson and his life’s achievement (as interpreted by the commission), and as a temporary war-time banner within the international rhetorical space of world war ii, providing that generation and its president with a rallying touchstone for the foundational principles of freedom which, in that moment, the united states was forced to defend. senator thomas recognised his own participation in a commemoration which was both historical and contemporary in : when democracy is being questioned in some parts of the world, it seems to me this will be a good influence to bring up at this time with the world on fire as it is, and the one great question in the world today is whether you are going to have government by force or coercion or government by common consent and liberty. this is a monument to those last two ideas (tjmc- march , ). making remarks in the house of representatives, louis ludlow concurred with thomas’ interpretation, elevating the memorial as an object involved in a project of remembering jefferson promotionally: at a time when tyrannical dictatorships are rising to the zenith all over the world and popular government is sinking to the nadir everywhere . . . i wish devoutly that the erection of this jefferson memorial might bring to every human being in the world a mental picture of the difference between dictatorships and rule by the people – between tyrants like napoleon and patriots like jefferson (tjmc- june , ). at key moments throughout the memorial’s creation, the president used his own rhetorical agency to cement the historical parallelism between jefferson’s age and his own. in , in preparation for the ground-breaking ceremony at the memorial construction site, roosevelt “requested this commission to arrange for a nation-wide hook up so that his remarks may be broadcast throughout the nation” (tjmc- december , ). roosevelt spoke as he was seated in his car, surrounded by members of the commission and beside his wife, eleanor. in the background, the secretary of war, harry woodring, “paced up and down, hands in pockets, in the cold,” energizing the scene with an acute atmospheric parallelism between the current and historical travails to establish american democratic principles. “jefferson,” roosevelt began, “has been recognized by our citizens not only for the outstanding part which he took in the drafting of the declaration of independence itself, not only for his authorship of the virginia statute for religious freedom, but also for the services he rendered in establishing the practical operation as a democracy and not an autocracy” (tjmc- december , ). at the memorial’s cornerstone-laying ceremony, roosevelt appropriated the symbolic parallels with jefferson with even greater zeal, stating: “he lived as we lived in the midst of struggle between rule by the self-chosen individual or the self-appointed few, and rule by the franchise and approval of the many. he believed as we do that the average opinion of mankind is in the long run superior to the dictates of the self-chosen” (tjmc- november , ). the surrounding press coverage confirmed the success of roosevelt’s strategy of aligning himself with the talismanic power of jefferson and the progressive ideal. under the heading “apostle of democracy,” the washington post underscored the memorial’s binary function to twin executive personalities and presidential eras: president roosevelt will be…participating in an act of rededication and consecration of profound significance to our troubled times. democracy was a frail and feeble plant when jefferson was alive. and outside the united states, governments almost everywhere were in the hands of despots. over a large part of the world that is now, unhappily, true again… long before hitler was born he saw the tragic fallacy of the fuehrer principle. long before the rise of the fascists, nazis and communists he exposed the tragic consequences of dictatorship… (tjmc- november , ). the rhetorical coordination of the memorial with roosevelt’s agenda was so overt that the washington daily news editorial, “jefferson on war,” remarked, “the president and his literary amanuenses might have done worse than commandeer old thomas jefferson himself as ghost-writer for the occasion.” so orchestrated was the echoic atmosphere that roosevelt tapped the cornerstone with “a gavel made from an elm which jefferson planted at monticello” (tjmc- november , ). if roosevelt’s partisan and contemporary arrogation of the jefferson myth was so visible to contemporary audiences, it has since faded from public memory. at the time of the memorial’s creation however, roosevelt was willing to risk short term reputational damage in order to secure a political legacy through the associative value of the memorial. “most monuments,” petrina dacres explains, “participate in establishing the legitimacy and authority of the state,” but, in the case of political monuments, it is clear that they can also promote the stability of contested partisan agendas under the veil of national accord. as demonstrated throughout chapter , the memorial’s quotations were perhaps the most subversive rhetorical technology available to roosevelt and his commission in order to legitimate and stabilize the contested progressive proposals underpinning the new deal. whether it is the transformation of jefferson’s specific statements on natural rights into aphorisms consistent with roosevelt’s wartime oratory; or the conversion of jefferson’s musings on educational roosevelt also orchestrated the eventual unveiling of the memorial for maximal rhetorical resonance, recommending that the date be postponed for one year so that it has “the advantage of the two hundredth anniversary of jefferson’s birth, thereby giving a sort of springboard on which to focus attention” (tjmc- january , ). gibboney endorsed the re-schedule, claiming that the memorial should become a pantheon of celebration, precisely because of the context of war: “we are fighting for democracy, so let us magnify and celebrate the founder of american democracy, not less, but more” (tjmc- january , ). the washington herald, for example, reminded readers that, whilst jefferson had designed his own modest tombstone during his lifetime, any elaboration of it is an act of third party aggrandisement: “one of the oldest examples of political flim-flam we ever saw is being circulated around town, belatedly, as the reason for this marble mass on the tidal basin. it runs about like this: ‘well, look here. lincoln was a republican. he has a memorial. and it cost plenty, too. what about jefferson? he founded the democratic party and what has he got?’ that’s the rather crass level on which to set even the monstrosity which is scheduled to go up as a ‘thomas jefferson memorial’” (tjmc- ). freedom into a trumpet-call for universal public education; or the transmutation of jefferson’s endorsement of constitutional evolution into a supporting affidavit of the radical overhaul of the new deal portfolio, roosevelt found in jefferson a nationally-cohesive icon for the celebration of his own partisan legacy, during the very era of its continuing implementation. chapter : the consequence – material rhetoric, public mis-memory, and the broken enthymeme building upon the demonstration of the nature and extent of the manipulations involved in the selection of the memorial’s quotations in chapter , and the analysis of the motivational forces working upon the rhetorical agents of the commission in chapter , this chapter grapples with the rhetorical consequences of the memorial’s continued existence. as such, this chapter calls upon a consideration of loewen’s final temporal stage of public memory: the visitor’s individual and collective experience of accessing the historical jefferson in the present. more specifically, the following analysis examines the memorial from a material rhetoric perspective, in order to understand how the memory object achieves the goals of its rhetors, as well as a variety of unintended (or unforeseen) consequences, in shaping public memory. accordingly, the memorial is subjected to the analytical framework for commemorative rhetorical objects proposed by carole blair, with a necessary limitation of focus upon the implications of the inscription controversy, namely: ( ) what is the significance of the text’s materiality? ( ) what are the apparatuses and degrees of durability displayed in the text? ( ) what are the text’s modes or possibilities of reproduction or preservation? ( ) what does the text do to (or with, or against) other ‘texts’? and, ( ) how does the text act on persons? finally this chapter proposes that the memorial engages its users within an enthymematic prefiguration, in which the major assumed premise (the tjm is an elite, accurate and authentic object, worthy of attention, investment and effort) encourages significant touristic visitation and the internalisation, acceptance and reproduction of the inscriptions as a material structure of public memory. arguably, the commission relied upon the subversive quality of the authenticity premise, creating a memorial which serves the aims of a s political philosophy, to the ongoing detriment of modern visitation and public knowledge. what is the significance of the text’s materiality? by this question, blair ( ) means to discuss how the appearance of a rhetorical text within a specific context moves upon or changes that context. that is, “what is different as a result of the text’s existence, as opposed to what might be the case if the text had not appeared at all?” ( ) memorials can mark changes in cultural contexts, they can establish issues, persons and events worthy of remembrance, and they can provide places to form communities missing, or lacking, in the public sphere. furthermore, the material installation of new monuments within particular landscapes has the potential to distract from, or enhance, the established interdiscursive qualities of a given community of memorial spaces. in washington d.c. in particular (where more than memorials exist), the act of memorialisation has been open to questions of commemorative saturation (e.g. savage ), whereby the introduction of new rhetorical sites has the potential to compete with, and weaken the impression of, existing material objects. the erection of a significant commemorative memory structure in washington d.c., devoted entirely to the works of thomas jefferson, (re)legitimized the third president as worthy of national prominence, cultural persistence and international visitation. in the words of the commission, “in a sense, we are erecting a $ , , billboard to advertise jefferson and everything connected with him” (tjmc- april , ). as an entirely created physical space, in the form of a classical pantheon, the memorial provides a destination of american pilgrimage for the singular remembrance of jefferson and his significance within the landscape of the nation’s founding and psyche . the memorial now functions as an unavoidable structure of the washingtonian skyline, “rising, as it appears to do, right out of the water which becomes its reflecting pool, exercis[ing] its glistening white tyranny over the eyes of all who stroll ‘round the tidal basin” (scarborough ). through its physical inscriptions, “in connection with this monument there should be something in an imperishable form in a separate memorial to preserve those writings that everyone likes to read… i do not refer to the preservation of the originals. i want to see the outstanding works preserved in bronze or marble. the monument that commands the attention of the thoughtful people above all other monuments in the world that i have ever seen is the monument to confucius, “the hall of the classics,” in peiping, where men come and remain not by the hour but by the day to study and be captivated by the writings. in your whole range of american history jefferson is the only man that can lend himself to that kind of commanding position.” (tjmc- june , ). the memorial purports to vocalize jefferson within a new public memory space and new physical rhetorical context. visitors experience jefferson’s words not in a public library or singular source document, but via the unique collocation, arrangement and form of the brass lettered quadrants of the memorial commission’s selection. the memorial’s materialization, two centuries after the historical object’s birth, communicates jefferson’s posthumous national celebrity and a presumed consensus of meritorious contribution. the memorial’s material existence interacts with the physical and symbolic characteristics of washington d.c.’s architectural complex in a number of meaningful ways. firstly, the memorial is purposefully located upon spatial coordinates which were marked out for exceptional utilisation from the moment that washington was selected as the seat of government. pierre charles l’enfant was appointed to design the new capital in by george washington, and was subsequently instructed by jefferson to provide a modest blueprint for planning sites for federal and public buildings (see appendix h). the city would be based on a series of grids, with streets running east to west and north to south. diagonal avenues created points of intersection for key buildings or plazas, including the “president’s house” and congress, connected by what would later become the national mall. l’enfant’s conception was extended and modernised by the mcmillan plan ( ) which re- emphasized the national mall complex as a monumental core of cruciform structure. the jefferson memorial occupies the same axis as the white house and the washington monument with the lincoln memorial to the north-east, and capitol hill to the north-west. the archives reveal that the memorial’s location was recognised by the commission as a crucial vehicle for the creation of automatic meaning and rhetorical significance, placing jefferson “on the last of the five cardinal points of the l’enfant plan conceived during the time of washington and jefferson who visualised and selected the shore of the potomac as the site of our great capitol city” (tjmc- november , ). as four of the cardinal points were already occupied, the materialisation of a memorial to jefferson completed washington’s core memory space. mr h.p. caemmerer of the fine arts commission called the location “the greatest site for a memorial in washington today,” concluding that “jefferson is worthy of that site” (tjmc- january , ). the commission concluded that “the american visiting his nation’s capital cannot help but sense the meaning of this arrangement” (tjmc- ). the siting of the memory structure places jefferson within a specific constellation of american presidential heroes: the orion belt of thomas jefferson, abraham lincoln and george washington. the creation of the memorial completed a conceptual triumvirate of celebrated early presidential characters, consistently recognised as the pre-eminent leaders of the united states. jefferson, lincoln and washington are each remembered through gargantuan classical stone formations – a roman pantheon, a doric temple and obelisk, respectively – historicizing their eras of power far beyond the actual geo-history of their own civilizations, and raising them (architecturally) to demi-god status within their republic. the commission consistently echoed this theological semantic when discussing the memorial’s proximity to the extant monuments. “[w]e are building something very much bigger than a memorial to thomas jefferson,” thomas wrote, “we are actually about to add another cornerstone in the formation of a structure which we may call the american national cult” (tjmc- , june ). hollins randolph envisaged the memorial as completing a mystical triptych of three presidential protagonists: “jefferson and washington and lincoln, all of them, should sit as near together as the law allows and the topography allows and the original plan of the city allows. they are together. they are the trinity. those are the three” (june , ). the faux classical temple design of the memorial, suggestive of national infallibility, comports with such an ethic of material beatification, but also architecturally denies the internal fallacies of the brass lettered inscriptions which are given the sense of jeffersonian scripture. the memorial’s material design also replicates and remembers jefferson’s personal architectural achievements and proclivities for the greco-roman form. despite his reputation for receiving “foreign diplomats in homespun boots” (tjmc- april , ), jefferson was undeniably a classicist, describing the roman pantheon as “the most perfect example of spherical architecture” in the world (scarborough ). jefferson used the design during his own architectural forays, including the design of his home at monticello and the significant rotunda at the head of the university of virginia, which he built as a hobby in his old age (also inspired by the villa rotunda near vienna). at william and mary college, jefferson, along with his associates chancellor wythe, dr william small and governor fauquior, “became absorbed no less with the perfection of classic architectural forms than with the government that gave rise to those forms” (april , ). whilst in france, he visited nimes and “gazed worshipfully for hours” at the maison carree “like a lover at his mistress” (tjmc- may , ). for jefferson, such architecture corresponded with the very fabric of the democracy he sought to establish, “realizing (as he pointed out himself) that our government was founded upon a greek concept of statesmanship – he found classic architecture to be the most suitable expression of his ideals for the republic’s buildings” (tjmc- , april , ) the memorial’s material rhetoric is also informed by the original conflict evoked by its proposed creation. objections cited the design’s lack of originality, the future usability of the tidal basin space, effects upon traffic flow, the lack of a utilitarian function and (most contentiously) the destruction of an established living memorial of cherry trees donated by the japanese government as a symbol of bilateral cooperation (tjmc april , ). some complained that the design was a mere replication of the national art gallery, whilst others suggested that the memorial was a cheap corollary to the republican iconophilia of the lincoln memorial. the commission was lampooned in the press, set back by initial congressional disapproval, and, at one point, subjected to a highly coordinated professional negative publicity campaign orchestrated by an alumnus of the university of virginia (tjmc september , ). in august , the commission was on the brink of resignation and plans were discussed to reserve the location for a future memorial to theodore roosevelt. the single- mindedness of the commission, and the personal agency of the incumbent president, ensured that jefferson alone secured the right to this privileged nexus of washington’s architectural and symbolic core – the automatic kudos of which contributes somewhat to its protection from serious critical deconstruction and distrust. what are the apparatuses and degrees of durability displayed by the text? blair’s second question seeks to differentiate material commemorative objects through the analysis of their respective durability and vulnerability. the fabric of rhetorical texts varies from site to site, and it is possible that such compositional qualities can communicate something of the text’s endurance and perceived importance. the memorial is materially, deliberately and durably, american. alabaster white danby marble from vermont was sourced to construct the monument’s exterior as well as the twenty-five marble columns (each made from six separate drum sections) with molded bases and carved ionic style capitals at a height of feet. “each column, before it was shipped to washington,” katherine scarborough writes, “was matched under supervision of the architect at the marble producer’s plant in vermont for color, tone and veining characteristics in order to secure a perfect harmony of material. over carloads were required, incidentally, to haul the stone to washington,” (december , ). tennessee pink marble was laid for the interior flooring space; white georgia marble was selected for the interior panels of the memorial room; grey missouri marble was selected for the statue pedestal; and bronze was chosen as the material for both the nineteen-foot statue of jefferson by rudolph evans and the quadrant lettering. due to metallic rationing during world war ii, a mock plaster statue, painted to look like bronze was initially installed prior to installation of the bronze version in . spanning the such conclusions are not altogether simple, however, as blair makes clear that whilst stone or metallic structures are ostensibly more stable and permanent than written or spoken discourse, they are often more vulnerable to attack, erosion, vandalism etc. the sourcing of the memorial’s composite materials is equally rhetorical. specifically, the debates over the suppliers of the memorial’s white marble, and the wartime priority acquisition of bronze for the inscription’s lettering and the central statue, communicates the importance of geography as well as the perceived importance of jefferson’s memorialisation despite the overt wartime preoccupation of the nation. a text’s durability and permanence is particularly important for our discussion in which composite materials ‘conspire’ with the perpetuation of error. to make alterations to a memorial, or to correct it, is to shade the quality of that permanence, and make vulnerable a text’s materiality – however durable. natural resources, and electoral map, of both the north and south of the nation, all of the construction materials harnessed for the memorial were deliberately “as native to american soil as jefferson himself” (scarborough ). the quotations of the memorial’s interior walls were cast in bronze, which had to be appropriated during a national war crisis and a scarcity of metallic materials. eggers warned chairman gibboney that “on account of the national defense program there is a demand for all kinds of metal and it is becoming harder and harder to get these bronze castings” (tjmc- february , ); accordingly, in january the priority on the bronze for the letters was withdrawn due to the declaration of war” (tjmc- january , ). the white house was eventually lobbied for assistance and a new priority gained, so that the installation of the bronze lettering was completed in april . that the visage of jefferson himself and his words share material durability is a meaningful and poetic parallelism between the memory of the man and the recollection of his language. the context of the metal’s procurement gives its use here particular cachet and material consequence, suggesting that the memorialization of jefferson was significant enough to draw upon the rationed resources of an america at war. bronze, since horace’s ode, has been recognized as a material of renowned strength, durability and artistic potential, and was pursued here, despite restrictions, to raise jefferson’s words and memory to a level of material endurance. to memorialise the selected quotations of jefferson in bronze was to suggest that this use of the restricted metallic compound was as important as (and connected to) the protection of american sovereignty by the deployment of the same material in weaponised form. as blair points out, however, durable materials such as stone and metal can be ironically “more vulnerable to destruction by hostile forces” ( ). indeed, jefferson had himself asked for his modest memorial obelisk at monticello to be “of the course stone…that no one might be tempted hereafter to destroy it for the value of the materials” (tjmc- ). today, the memorial, which is open to the public the substantial quantity of bronze required for the statue of jefferson ( tonnes) was not made available until the end of the war. hours a day, has fallen victim to material vulnerabilities. in , the memorial was vandalised with oil that was sprayed in crosses by religious groups upon the white marble interior panels, which left permanent staining (kilian ). in - , the tidal basin seawall was repaired to save it sinking amongst “primordial porridge” (ruane ). in october , a five-foot long portion of the limestone ceiling collapsed within the memorial room due to water damage caused by a leaking gutter (wtopstaff ). according to megan nortrup ( ), science communicator for the national capital region of the national park service, acid precipitation is causing significant degradation of the marble within the memorial, specifically “the loss of silicate mineral inclusions in the marble columns as the calcite matrix holding them together is dissolved.” due to the weakening effects upon the stone, ties were installed to prevent sections falling from the volutes, and restoration work in removed accumulated “black crusts.” most significant is the inevitable degradation of the bronze lettering which has succumbed to the green pigmentation of verdigris, caused by the exposure of the brass to half a century of weathering. today, the patina staining can be seen running down the white marble quadrants beneath the raised letters leaking into the fabric of the building as the words themselves have the capacity to corrupt the public remembrance of jefferson. the paradox of the memorial’s durability and vulnerability, therefore, offers opportunities to remedy the misrepresentation or slanted re- contextualization of jefferson via the bronze inscriptions. the detrimental effects of acidic precipitation, vandalism of the panels and the bronze verdigris might offer an opportune moment for the replacement of bronze lettering to correct some of the most egregious fallacies of the extant inscriptions, as a mode of the memorial’s material preservation. what are the text’s modes or possibilities of reproduction or preservation? “reproduction,” blair insists, “is an intervention in the materiality of the text, and it is important to grapple with the degrees and kinds of change wrought by it” ( ) reproduction can increase the public access and experience of texts, but in the case of material rhetorical objects – such as monuments – reproduction (via guidebooks, photographs, three-dimensional postcards etc.) can provide an inauthentic, incomplete or re-interpreted version of that text. the jefferson memorial is an object of diverse and numerous replications. the commission, which had already preserved its own brand of reproducing jefferson’s texts through the memorial, also authorized the publication of a four-page leaflet replicating some of the included quotations, whilst providing a commentary that supported the interpretative bent of the commission’s specific re- contextualization(s) (tjmc- january , ). a more substantial -page booklet was also drafted, providing an entire section that reprinted the inscriptions as they appear in the rotunda, prefaced with the paralleling statement that “however true they were at the time of writing, they are more significant at this critical moment in world history” (tjmc- ). the quotations are reproduced, and repackaged to purposefully underline their contemporary reclamation. the modern visitor is similarly exposed to facsimile reproductions of the memorial and its textual content. “the words of thomas jefferson” (appendix i) is a one-page replication of the inscriptions available from the memorial bookstore, and countless leaflets, such as those produced by the national park service reiterate select quotations as accurate and direct jeffersonian statements. the memorial’s prominence as a symbol of americana has led to its replicative omnipresence in popular culture. the memorial features in the opening credits to news programming, such as msnbc’s morning joe, to immediately establish a national political context. it is deployed during scene transitions and sweeping cutaways to establish geographical context in political dramas such as house of cards, scandal, and the west wing. the frieze quotation performs a narrative function in the satirical films bob roberts, and billy jack goes to washington, and the inscriptions spur discussions of what democracy means in born yesterday. so ubiquitous is the memorial that it featured in an episode of the simpsons (season , episode ), in which jefferson’s statue complains that lisa simpson has only visited his monument because the lincoln memorial is overcrowded. the memorial has appeared on postage stamps, such as that designed by dean ellis in ; pillowcases, mugs, tote bags, mouse pads, and all of the usual souvenir ephemera have featured the monument and its textual content. a cursory search on google.com provides over , , individual results for “thomas jefferson memorial.” in the process of reproduction, blair writes, “[s]ometimes what appears to be the rhetorical text is not the rhetorical text, but an altogether different one” ( ). that point is even more acute when the original rhetorical text is demonstrably inaccurate prior to its reproduction or preservation. indeed, where memorials include inscriptions of previously spoken or written discourses, the quality of reproduction is multiplied. at the moment of inscription a text has often traversed a series of significant publication reproductions. when dealing with the issue of error perpetuation, the modes and possibilities of a text’s reproduction or preservation are issues of some importance. fallacious quotations reproduced or preserved have consequence for those who receive them, and signify the intention of the rhetors involved in their materialisation. the reproduction of these texts through repeated visitation, gift shop reproductions and the national appropriation of the memorial as a symbol of justice, equality and democracy in various media, advances the dangers of a material commemorative rhetoric when its constituent texts are made to be simultaneously durable and misleading. what does the text do to (or with, or against) other texts? blair admits that this “is one of the more difficult questions to address because the linkages among texts can be so varied and numerous” ( ). in light of this unquantifiability, blair is sensible to limit these linkages or conversations to those among memorial sites and between memorial sites and their “immediate contexts.” according to blair, memorial texts can be “enabling, appropriating, contextualizing, supplementing, correcting, challenging, competing and silencing” towards others, though they can surely engage in other relationships too. washington d.c., as a physical centre of enlightened western democracy, american independence and the seat of government, also poses some of the most tangled and incestuous relationships among sites of memorialisation. the jefferson memorial supplements and appropriates the established vernacular of washington’s greco-roman architectural examples, connecting itself to their imposing statues, words upon walls, ascending stairways, domes, pediments and reflective pools. the memorial relies upon the audience’s familiarity with washington’s commemorative syntax and encourages an intertextual reading among the cardinal points. the assumption of this material vocabulary performs a number of functions: it connects utilitarian buildings with the purely commemorative, aligns contemporary government with historical presidencies, and importantly provides the memorial – and its inscriptions – with a sort of automatic authenticity amongst its architectural neighbours. the jefferson memorial’s inscriptions, however, have the potential to challenge the authenticity of the washington constellation, or to blemish the very symbolism of transparent democratic government that it purports. its perpetuation exacts reputational damage to an already maligned washington, famous as a topography of mistruth, partisan manipulation, and low standards of accuracy. the memorial’s creation not only involved the appropriation of the authenticity of surrounding sites, but also necessitated the partial and controversial silencing of a highly motivated memory space. prior to the monument’s construction, the tidal basin was already home to almost , japanese cherry trees that had been donated to the united states from mayor yukio ozaki of tokyo (encouraged by jokichi takamine, a japanese chemist). these cherry trees became a living symbol of the friendship between the two nations and, accordingly, the united states responded with a donation of blossoming dogwoods to the japanese nation, placing the memorials within a transactional diplomatic context. this “outstanding monument of international good will around the tidal basin” is the focal point of the national cherry blossom festival, which has taken place since . the proposal to construct the memorial was met with its strongest opposition from those who objected to the potential destruction or interruption of the tree-lined shore of the tidal basin. newspapers magnified the issue to a level of national controversy, with editorials petitioning the white house to reconsider the plans: “substantial damage will be done to this community if the simple beauty of the cherry trees is impaired... they are literally assets of great worth to the business of washington, and material, substantive damage will be inflicted…if those trees are touched” (tjmc- ). according to critics, the president was complicit in a macbeth-like drama, orchestrating “the scandalous workings of a gang” in a “distinctly skulking” process: “as things stand now…a world-famous spectacle of natural beauty will be shattered…by an invasion of men with picks, steam shoves, trucks and axes, unless the people force one public official to exercise his absolute power to restrain their vandalism” (tjmc- , april , ). as the embattled clubwomen of washington d.c. chained themselves to cherry trees in protest, the commission and the president dismissed the hype. the commission reported that only trees were potentially affected (tjmc- , november , ) and installed a billboard illustrating that the increased land would provide space for the planting of a large number of new trees (tjmc- december , ). thomas remarked that “if cutting those cherry trees was a declaration of war on japan, i should not do it, but there are plenty of them along the western boundaries and at haines point where they can be placed with the others” (tjmc- june , ). the memorial and its highly motivated inscriptions, therefore, materially disrupted a national symbol of us-japanese friendship. if jefferson’s memorial was shaped by an activist ethic to showcase american freedoms against the rise of international tyrannies, then its impact upon the cherry tree memorial might be read as a highly motivated parallel rhetorical act. prior to pearl harbor, the possibility of war with japan had existed since the s. the invasion of manchuria in and japan’s subsequent encroachments into china, as well as the axis alliance with nazi germany and italy, strained the very signification of the cherry tree memorial. due to emerging sensitivities, the cherry blossom festival was suspended during world war ii; the trees were temporarily labelled as “oriental” rather than explicitly japanese, and in response to pearl harbor a small number of trees were cut down by protesters. the material interjection of the tjm and its brass lettered quotations, within an already complicated and motivated memory space, provided an immediate world war ii conversational context for jefferson’s voice to oppose international aggression, restricted liberties and anti-american values. if the inscriptions were manipulated to form contemporary vocalizations of roosevelt’s foreign policy, the tidal basin provided an unparalleled material and metaphorical diplomatic arboreal space for that ventriloquization. how does the text act on person(s)? fifth, and most importantly for the heuristic of materiality, blair asks how the text acts on person(s). a material approach recognises that a rhetorical text, as a destination, can make particular demands upon the visitor’s body, intruding into our material existence. “memorials do perhaps even more obvious work on the body,” blair writes, as “they direct the vision to particular features, and they direct – sometimes even control – the vector, speed, or possibilities of physical movement” ( ). surrounded by a mass of cherry blossoms against the shore of the tidal basin, the startling white superstructure of the pantheon-style jefferson memorial immediately summons visitation as an aesthetic destination. upon arrival, the visitor traverses a series of steps leading to the interior memorial room which, with its central idol and panels of “scripture,” has the sense of a spiritual space, or temple. accordingly, as i observed on each of my several visits, the interior of the memorial induces the majority of visitors to a state of noticeable – and respectful – hush. the physical reflection of the memorial within the tidal basin gives rise to a contemplative atmosphere, with internal benches and the surrounding steps offering on-site locales for rumination upon its contents. the visitor experiences each of the memorial’s panel inscriptions in relative isolation, spaced as they are between the four compass-point entrances to the memorial room. the inscription-entrance- inscription-entrance architectural pattern demarcates the quotations as discrete textual wholes, connected by the continuous overhead frieze quotation. the archives reveal supporting evidence that the commission attempted to prescribe the order for experiencing the recontextualized inscriptions, calling upon psycho-spatial studies. kimball “assumed that no. (from the declaration of independence) would be the first one on the right as you enter…in accordance with the psychological studies that at least % of [test subjects] turn to the right, following our habit of walking and driving” (tjmc- , oct , ). eggers agreed that the “majority of the people do turn right on entering a place to view what may be exhibited on the walls,” proposing the arrangement of tjmpb on the southwest quadrant, tjmpe on the northwest quadrant, tjmpc on the northeast quadrant, and tjmpd on the southeast quadrant. this arrangement ensured that the declaration of independence panel retained primacy in the visitor’s reading (tjmc- november , ). the order of the memorial’s inscriptions invokes the declaration’s celebrity to initiate a sense of textual familiarity and also encourages the visitor to presume the fidelity of subsequent panels, despite their lesser renown and fallacious content. a consideration of the memorial from the perspective of blair’s rhetorical inquiry, demonstrates the various ways in which the monument’s materiality provides significance, endurance, and replication to the fallacious and inauthentic apparatus of the memorial’s inscriptions, which, in turn, have intended (and unintended) effects on their audiences. sites of public memory are also bordered within material and symbolic contexts. a memory place such as the jefferson memorial is constructed within the larger memory field of the monumental core of washington d.c., a city that exists as a real and imagined place and that metonymically expresses ideas far beyond its mere geography. such memorials are not just any interventions in public memory. memory places are self-consciously constructed by and for persons with individual and group interpretations of particular events. they are, in their sheer manifestation, partisan, and as a result of this partisanship they are rendered, by virtue of their rarity, as supposedly accurate, authentic and worthy objects of public consumption. that a memorial exists in the nation’s capital defines it as a hyper-rhetorical object of settled public memory, with the most elite forms of partisanship and authenticity. a memorial in washington d.c. demands a touristic commitment in exchange for the transmission of approved, nationally consequential and trustworthy information. in a sweeping survey of american attitudes towards methods of history learning, for example, rosenzweig and thelan found that museums and physical sites of public memory were the most trusted sources of historical information ( ). such sites score more highly for authenticity than direct conversations with family members, eye witnesses, history professors, teachers, books and visual media: americans put more trust in history museums and historic sites than in any other sources for exploring the past...approaching artifacts and sites on their own terms, visitors could cut through all the intervening stories, step around all the agendas that had been advanced in the meantime, and feel that they were experiencing a moment from the past almost as it had originally been experienced – and with none of the overwhelming distortions that they associated with moves and television, the other purveyors or immediacy...many respondents felt there was nothing between them and the reality of the past...museum visitors could form their own questions by imagining that they were re-experiencing for themselves – without mediation – moments from the past ( ). the public’s qualitative assessment of memorials as devoid of agenda, distortion and mediation runs entirely counter to the archival evidence of motivated historical manipulation. through the lens of material rhetoric, interaction with a site’s materiality “predisposes its visitors to respond in certain ways, enthymematically prefiguring the rhetoric of the place as worthy of attention, investment, and effort (at the very least)” (dickinson, blair and ott, ). this prefiguration is part of the mode of often invisible mediation, appropriated by the authors of particular memory places as a foil for historical immediacy. the complete structure might be presented as follows: sites of public memory are elite, accurate and authentic objects, worthy of attention, investment and effort. major premise – assumed the thomas jefferson memorial is a site of public memory. minor premise – assumed the thomas jefferson memorial is an elite, accurate and authentic object worthy of attention, investment and effort. conclusion - stated the thomas jefferson memorial engages its users in a fallacious rhetorical relationship, enacting a betrayal by subverting the expectation of an accurate and authentic memorialisation of the third president of the united states. the major assumed premise of this first order enthymeme has been found to be false in its assumption and, if the panels are left unchanged, the memorial appropriates the kudos of public memory objects in order to advance an inauthentic (yet trusted) version of american history. “epistemologically, memory places are frequently understood as offering a unique access to the past,” dickinson, blair and ott find, “but authenticity isn’t something that places just have. a sense of authenticity is a rhetorical effect, an impression lodged with visitors by the rhetorical work the place does” ( - ). the jefferson memorial is a single, high profile public commemorative object, invented in part as propaganda, wrapped in a pantheon, gifted to the world as a signification of fact, and received by its visitors as a heretofore largely un-interrogated and pure revivification of the thomas jefferson. the memorial commission relied upon the material nature of the memorial itself to acculturate its public with the highly motivated characterisation of the founding father as a leading light of rooseveltian progressivism. the “rhetorical work” of the commission was to smuggle statements supportive of world war ii intervention, new deal programmes, federal enlargement, and educational reform, into a memory space orchestrated to frame such words in a material cocoon of historical authenticity and consensus. as part of their material rhetoricity, these quotations can be demonstrated to be culturally significant, permanent, durable, replicable, corruptive to surrounding material memory sites, and disruptive to the relationship between america’s past and her public. with each day of the memorial’s persistence, the opportunistic reclamation of jefferson (by a sitting u.s. president no less) is given a greater cachet of commemorative authenticity. as a case study, this thesis has attempted to lay the groundwork for the identification of commemorative rhetorical fallacy, the utilisation of archival records to ascertain the footsteps of memorialising motive, and the deployment of a material rhetoric framework to qualify a (misleading) memorial’s consequence within a physical culture and zeitgeist. a comparative analysis of the rhetorical formation of other political memorials within the monumental core of washington d.c. is recommended to examine the extent to which the thomas jefferson memorial is either emblematic or anomalous in so explicitly serving the agenda of partisan proselytization. epilogue despite the inscriptions’ exponential detrimental impact upon jefferson’s public memory, awareness surrounding the concoction of the memorial’s inscription content is negligible. ronald hamowy, a professor emeritus in intellectual history, is a rare proponent of the theory of the memorial’s partisan appropriation, claiming that it is “perhaps the most egregious example of invoking jefferson for purely transient political purposes” ( ). hamowy +has criticized the cumulative effect of the quotations which suggests that “jefferson advocated positions consistent with the aims of the new deal – with which he would, in fact, have had little sympathy.” despite the force and clarity of hamowy’s claims, however, they exist only as a tangential point in an obscure book review, on the periphery of academic discourse. historian garry wills has bemoaned the slavery panel, in particular, as “misleadingly truncated” for its eradication of jefferson’s clear vocalisation of the slaveholder interest. the only serious journalistic intervention on the subject was that of nicholas kristoff (new york times) who, in , focussed his opposition on tjmpb and the misquotation from the declaration of independence: “[t]hat sentence is one of the greatest in american history, and it’s a disgrace that it’s improperly written on the wall of the jefferson memorial.” the intent of the preceding pages has been to provide comprehensive archival and rhetorical substantiation to the whispered accusations of deliberate misquotation which have yet to gain traction in the public sphere. at the risk of tinging a thesis with advocacy, one might ask whether any action should be performed to mitigate or revise such an elite object of misleading national memorialisation. the exigence for such an intervention is supported by a recent appetite for correcting the so-called errors of extant memorials. in , for example, one of the two engraved quotations of the martin luther king memorial in washington d.c. (“i was a drum major for justice, peace and righteousness”) drew heavy criticism for its misrepresentation of king as a rhetorician and historical character. this selective quotation from king’s drum major instinct sermon neutered the anaphoric ascension of king’s peroration, and removed the initial conditional phrase which in turn expunged the essential self- effacement of the original. the truncation led to an overall tonal change that maya angelou said made king sound like “an arrogant twit” (weingarten and ruane ). when dedicating the monument in october , president obama felt it necessary to gloss the engraving: “what he really said was that all of us should be a drum major for service, all of us could be a drum major for justice, and there’s nobody who can’t serve” (siddiqui and brower ). following considerable objection to the engraved quotation, ken salazar, secretary of state for the interior agreed that the inscription should be altered, tasking the king memorial foundation to find a substitution. “this is important,” salazar said in early , “because dr king and his presence on the mall is a forever presence for the united states of america, and we have to make sure we get it right” (manteuffel ). the episode was speared by television satirist stephen colbert, who described the monument as “to the point. not dr king’s point, but still. brevity is the soul of saving money on chiselling fees.” in august , the sculptor erased the disputed inscription from the statue but did not replace it, and instead reworked the side of the memorial with a new, inscription-less finish (in what might be understood as a richly rhetorical act in itself, proffering silence in place of controversy). importantly, the martin luther king example suggests that a culture exists which is prepared to upend “carved in stone” permanence and to interrogate the material consequences of fallacious mnemonic content in washington’s monumental district. this responsiveness, however, sits in contra- distinction to the veritable obliviousness surrounding the errors of the jefferson memorial, which are demonstrably more deleterious and far-sweeping than a single truncation and alteration of tone. in attending to the material consequence of an inauthentic historical narrative, however, and cognisant of the enthymematic prefiguration of a memorial’s role in public understanding, a number of practical options for the partial remediation of the thomas jefferson memorial might be considered, as follows:  the replacement of the current inscriptions with quotations from identifiable single sources, selected via committee or public/academic consultation.  the re-presentation of the current quotations, recording the extent of textual manipulation through standard typography.  the inclusion, within the memorial room, of clear source attribution for each panel via additional plaques, engravings or moveable signage.  the training of national park service steward staff in order to provide contextual information, relating to the composition, motivation and consequence of the selected quotations, to the memorial’s visitors.  the addition of a section in the jefferson memorial museum space relating specifically to the work of the thomas jefferson memorial commission, the process of inscription selection and the reclamation of jefferson for contemporary rhetorical deployment.  the provision of enhanced educational materials that underline the nature of the textual content and its role in creating a highly motivated and tendentious jeffersonian memorial. each of these options for modification, however, is subject to the same complications of agency and motive as those faced by the memorial’s original rhetorical creators, such that our corrective actions might be read by future generations as merely additive to the commemorative object’s already contested rhetorical formation. bibliography the thomas jefferson memorial commission: general records, - . record group : records of the national park service, - .

john locke; private property; declaration of independence; re- publicanism. in chapter , section , of his second treatise, john locke famously wrote that “the state of nature has a law of nature to govern it, which obliges everyone: and reason, which is that law, teaches all mankind, who will but consult it, that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.” albeit in the declaration of inde- pendence thomas jefferson ( - ) omitted locke’s mention of property and replaced it with the phrase “pursuit of happiness,” property has never been for him an obstacle to republicanism, a hindrance to egalitarianism, and a moral embarrassment. on the contrary, property was an es- sential facet of jeffersonian political thought. according to jefferson, property neither fostered a society of self-seekers, nor promoted a purely instrumental and adversarial relationship between individuals and the political community. those who think that in principle property must be incompatible with jefferson’s egalitarianism and the very spirit of the declaration are prey to a prejudice of precisely definable lineage. nineteenth-century european social thought, notably the so-called hegelian left (which in- cluded karl marx and friedrich engels), keenly insisted on the intrinsic injustice of “private prop- erty.” furthermore, the hegelian left was so successful in its line of reasoning that a great deal of locke, two treatises on government, . word count does not allow a thorough analysis of the topic of the “pursuit of happiness.” but see conklin, pursuit of happiness in the founding era. i thank the two anonymous reviewers for their constructive comments. ricognizioni. rivista di lingue, letterature e culture moderne, • (vii) maurizio valsania twentieth-century social theory considered it obvious that property must, one way or another, be treated as scandalous and a perversion of the natural order. perhaps hegelians were too successful in their argument inculcating in the historical profession itself the anti-historical dogma that all intelligent, responsible, and morally upright persons, no matter where and when they could have lived, must have acknowledged the plain fact of the undesirability of acquisitiveness. that a worship of private property was dangerous was ingrained in the idea that georg wil- helm friedrich hegel had of the american society. the “fundamental character of the [american] community,” as he put it in his lectures on the philosophy of history, is “the endeavor of the in- dividual after acquisition, commercial profit, and gain.” scandalous, for hegel, was “the prepon- derance of private interest, devoting itself to that of the community only for its own advantage.” property has corrupted morality and undermined the ethical state. american society is a political community in which “the state [is] merely something external for the protection of property.” the property, that is, of its “atomic constituents.” hegel’s vision inspired his disciples, especially karl marx and friedrich engels. for their part, they certainly have been correct in their denunciations of the shortcomings of a society built on private property and deliberately ignoring the moral imperative that property must always be under the regulation of the civil society. hegel’s complaint has a noble pedigree. it resonates with jefferson’s rebukes of luxury and adam ferguson’s famous jeremiad about the “refinements” of the civilized age: “the boasted refinements, then, of the polished age, are not divested of danger. they open a door, perhaps, to disaster, as wide and accessible as any of those they have shut. if they build walls and ramparts, they enervate the minds of those who are placed to defend them; if they form disciplined armies, they reduce the military spirit of entire nations; and by placing the sword where they have given a distaste to civil establishments, they prepare for mankind the gov- ernment of force.” hegel reenacted an old republican song, almost a foreboding of impending doom, dating back at least to cicero. according to all republicans of all times, attachment to one’s country would be undermined by unbridled acquisitiveness, the calculus of profit and loss, and private property. that america could lose its soul and become that kind of aggregate of private properties de- nounced by hegel represented, in fact, jefferson’s worst nightmare. but this does not authorize any “marxian” reading of jefferson. jefferson did not consider property as scandalous. some his- torians and political scientists, of course, take a different view. richard matthews, for example, correctly argues that for jefferson “positive law, not natural right, creates property rights.” he insists on “jefferson’s explicitly rejecting property as a natural right.” for matthews, jefferson was a downright positivist in the matter of property: “property is merely an institution created by society to help men gain ‘life, liberty, and the pursuit of happi- ness’.” however, using the positivist argument to conjure up jefferson as a radical egalitarian—the same figure upon which early nineteenth-century american socialists built their theories—is in many ways problematic. matthews abides by staughton lynd’s hypothesis that in jefferson’s prin- hegel, philosophy of history, , . ferguson, an essay on the history of civil society, - . “ferguson’s closest reader would be wilhelm friedrich hegel, who incorporated many of ferguson’s ideas and even phrases into his own philosophy of history, which karl marx would take up and develop.” herman, scottish enlightenment, . matthews, radical politics of jefferson, , . itinerari thomas jefferson on private property ciple that “the earth belongs in usufruct to the living” the american revolution “approached most nearly the socialist conception that living labor has claims superior to any property rights.” jeffer- son, lynd’s argument continued, “seemed to imply that, in the absence of remedial state action, the unemployed might rightly take the land they needed.” jefferson, matthews is convinced, wanted “to institutionalize revolution in order to keep the spirit of perpetually alive.” he did not hurry, as matthews allows, but “perpetual transition is precisely what jefferson wants.” matthews arrives at his conclusion that jefferson wanted to institutionalize revolution via a close reading of the “usufruct” letter to madison of september , . one passage in particular strikes matthews in a special way: “but the child, the legatee, or creditor takes it [the parcel of land], not by any natural right, but by a law of the society of which they are members, and to which they are subject.” discussing the question of inheritance laws, as matthews recognizes, jefferson wanted to clarify that the church, hospitals, colleges, orders of chivalry, and so on, have no natural right to the appropriation of land. assessing the traditional mechanisms of appropriation of land and hence of power, jefferson wryly denounced this ancient habit of appropriation that allotted power “to hereditary offices, authorities and jurisdictions; to hereditary orders, distinctions and appellations; to perpetual monopolies in commerce, the arts and sciences; with a long train of et ceteras.” we can easily agree with matthews in every point and admit that, for jefferson, every living society should reaffirm all its statutes, institutions, and laws approximately every twenty years, including the inheritance laws. were this reenactment omitted, some types of property might result in an usurpation based on “an act of force, and not of right.” true as this is, however, the letter cannot be construed in a way that proves that jefferson considered property per se to be a usurpa- tion to be counteracted by a perpetual transition of assets. any socialist reading of jefferson is biased. the focus of the letter is whether or not “one generation of men has a right to bind another.” when a society “has formed no rules for the ap- propriation of it’s lands in severalty, it will be taken by the first occupants.” this is a natural right. if rules and laws exist, they can either sanction an act of force, or of right. in the first case, a gen- eration is binding another, as happens especially in europe and everywhere unnatural aristocracy, ibid., , . lynd quoted at - , . see lynd, intellectual origins, , , . for instance, we can easily remove from the context of the shays’ rebellion what jefferson said in a famous letter to james madi- son, jan. , papers of thomas jefferson (henceforward ptj), : , to give a further boost to matthews’s radical jefferson: “i hold it that a little rebellion now and then is a good thing, and as necessary in the political world as storms in the physical.” tj to james madison, sept. , ptj, : - , passim. see also matthews, radical politics of jef- ferson, . for a very convincing interpretation of this remarkable letter, see sloan, principle and interest, - . like all complex documents, sloan argues, the letter can be read in a number of ways. over time, jefferson would find new applications for the ideas he expressed at the end of . nonetheless, “debt is the key, and whatever else this insistence ‘that the earth belongs in usufruct to the living’ means, it is first and foremost a confession of what debt meant to thomas jefferson.” ( ) burstein and isenberg admit the centrality of debt. in addition, they also stress the character of a mental experiment: jefferson “hazarded a new and experimental view”; he “was not prescribing policy so much as opening a conversation about an issue he and madison both cared about: possible ways to fix limits on public debt.” burstein and isenberg, madison and jefferson, - . upon his return from france, jefferson was especially excited by the possi- bility of a fresh start, not corrupted by history: “he imagined being able to reshape society.” ( ) by no means did such a philosophical discourse on possibilities imply that he was “preparing to unleash social and political chaos.” ( ) itinerari maurizio valsania including orders, distinctions, and appellations, thrives. (this means that orders, appellations, and so on, take advantage of outdated laws, not reaffirmed by the living generation.) in the second case, the living generation reenact laws and institutions “as they please”: the living generation can transform the laws that were about to become a mere act of usurpation into something rightful and legitimate. the living generation can rewrite these laws, or adjust them, or even, willingly, take them as they are. unsympathetic though he was to the atomization of society, what jefferson was arguing is more limited and more circumstantial: “from the nature and purpose of civil institutions, all the lands within the limits which any particular society has circumscribed around itself, are assumed by that society, and subject to their allotment only. this may be done by themselves assembled collectively, or by their legislature to whom they may have delegated sovereign authority: and, if they are allotted in neither of these ways, each individual of the society may appropriate to himself such lands as he finds vacant, and occupancy will give him title.” the thesis, as stated, is that dis- assembled individuals and single laborers have the right to appropriate individually and according to their personal interests only such land as society has chosen not to allot. no mention is made of the nature of property in general as subordinate to the rights of labor. society, not laborers as such, has the superior right. finally, matthews’s biggest mistake is drawing on the declaration to demonstrate that jef- ferson’s failure to mention property among the inalienable rights translates automatically into a judgment of value. “the omission is significant. while locke views property as a natural right … jefferson does not.” why should it be so “significant”? as garry wills demonstrated, “pursuit of happiness” was a better and more precise phrase than property. “pursuit of happiness,” in the period, signified the right of american citizens to cul- tivate themselves, to pursue the realization of a proper end, in this way rising above the level of brute existence. as wills made clear, few used it vaguely, and certainly not jefferson. his most likely “sources” were in turn very precisely identifiable: hutcheson, ferguson, lord kames, burla- maqui, james wilson, george mason in “virginia declaration of rights” ( ), and locke in chapter , “of power,” of essay concerning human understanding ( ). the phrase did not evoke a vague aspiration (happiness was the realization of a proper end), and jefferson would have been quite an eccentric to list a fanciful wish among the rights that governments should pro- tect. as wills writes, “jefferson meant to state scientific law in the human area—natural law as human right. … man pursues happiness as the stone falls. … the stone must fall, but it does not— the illustration is diderot’s … . only when one recognizes the law of man’s nature as his right does one remove the obstacles and let him move free, knowing this is consonant with the order of nature.” in the declaration, jefferson omitted to list property among inalienable rights because he had good reasons to do so. by their nature, in a necessary way, humans pursue life, freedom, and happiness, while property is obviously alienable. property helps to make me the individual i am. but i can easily bequeath all my properties, or part of them, to somebody. i can run into debts. i matthews, radical politics of jefferson, , . on jefferson’s “bold innovation,” see . tj, summary view, ptj, : . according to matthews, jefferson was “inform[ing] the king of the rela- tionship between property and labor.” matthews, radical politics of jefferson, . ibid., . see wills, inventing america, - , quotation at . on mason’s declaration, see also maier, american scripture, - . itinerari thomas jefferson on private property can gamble and lose. war can rob me of my estate. after all, humans are very vulnerable beings. similarly, the living generation might rightfully reform all the extant laws concerning property. that jefferson did not list property among those rights does not make property something despicable; and it does not make perennial revolution a desirable condition. the mistake is that matthews associates the term “inalienable” with predicates such as “significant,” “important,” and “morally correct.” each society, as matthews allows, certainly has “a right to govern itself in terms of property usage.” the declaration’s omission may well signify that “property is merely an in- stitution created by society to help men gain ‘life, liberty, and the pursuit of happiness.” but this does not imply any reproof. admitting that jefferson was a positivist in the matter of property rights, that he believed property laws should be altered and refined every twenty years or so, that property was “merely” a convention, does not mean that, for jefferson, property in the long run becomes a hindrance to the realization of social happiness. matthews approves of charles wiltse’s argument that jefferson’s political theory conveys “an organic conception of society.” but jefferson’s “organic conception” must not be confused with socialism, that property is either a theft or a phase to be dialectically outstripped in the his- torical process that would restore the natural rights of laborers. when matthews stresses that jef- ferson’s view of property was “similar to that held by rousseau,” he closes his circle. he was sure from the outset that rousseau was the neglected source of jefferson’s social thinking. as far as the origin of property is concerned, rousseau was the main advocate for the moral reprobation of private property: “the first man who, having enclosed a piece of ground, bethought himself of saying ‘this is mine’, and found people simple enough to believe him, was the real founder of civil society.” according to rousseau, private property was the upshot of an act of usurpation of the propertied against the rights of the un-propertied. schooled in the eighteenth- century idea of a natural sociability and natural sympathy among individuals, jefferson could not have consented in rousseau’s hypothesis. for him, the history of civil institutions, at least in amer- ica, was not a perversion of the natural pre-historical order. let us consider jefferson’s most seemingly rousseauian explanation of the origin of property. unquestionably, he admitted of property as not founded in nature but in human laws. how earth- shaking this opinion was, however, is still to be determined. in discourse on political economy ( ) rousseau himself called property a “sacred right” without ever regarding it as a natural right. to isaac mcpherson, jefferson wrote: “it is a moot question whether the origin of any kind of property is derived from nature at all … it is agreed by those who have seriously considered the subject, that no individual has, of natural right, a separate property in an acre of land, for instance. by an universal law indeed, whatever, whether fixed or moveable, belongs to all men equally and in common, is the property, for the moment, of him who occupies it; but when he relinquishes the occupation the property goes with it. stable ownership is the gift of social law, and is given late in the progress of society.” it is a “moot” question, first of all, and, in addition, it is hard to discern any trace of moral reprobation in what jefferson said. provided that society is a second-order nat- ural occurrence, a gift of social law sanctioned by the living generation can be as sacred as a law matthews, radical politics of jefferson, , . for a more convincing discussion of jefferson and property as alienable, see yarbrough, “jefferson and property rights,” especially - . wiltse, jeffersonian tradition, . quoted in matthews, radical politics of jefferson, . on jefferson and rousseau, see . rousseau, discourse on inequality ( ), part , incipit. itinerari maurizio valsania that comes directly from nature herself. the social order to which the living agree, at least the american order, is not in principle an unnatural perversion, even when it admits “separate prop- erty.” another jeffersonian document makes the point still clearer: a right of property in moveable things is admitted before the establishment of government. a separate property in lands not till after that establishment. the right to moveables is acknowledged by all the hordes of indians surrounding us. yet by no one of them has a separate property in lands been yielded to individuals. he who plants a field keeps possession till he has gathered the produce, after which one has as good a right as another to occupy it. government must be established and laws provided, before lands can be separately appropriated, and their owner protected in his possession. till then, the property is in the body of the nation, and they, or their chief as trustee, must grant them to individuals, and determine the conditions of the grant. once again, there is no trace of moral reprobation. the myth of redistribution the key point of the whole discussion of property is not whether jefferson deemed property of land and other immovable things as directly or indirectly founded in nature. more important is how he considered the social consequences of what we would call private property. did he frown upon inequality? did he consider stable property a theft perpetrated against the rights of laborers? did he see in private property an obstacle to the full expression of human subjectivity? we have to keep in mind that the living generation, not laborers per se, were for jefferson sovereign. like every other “class,” laborers relinquish their power as they enter society. classes, that typical european staple, should not exist in america. furthermore, the “self-evident truth” tells that the earth belongs in usufruct to the living. when an individual dies, his property “reverts to the society” which means “a whole generation of men,” not a specific class. the earth belongs to them, jefferson says, “fully, and in their own right.” individuals, groups, and classes, we have to remember, are “parts only of a society, subject to the laws of the whole.” each time we contem- plate this whole, we must also acknowledge that “there is no superior.” this is the plainest meaning of the phrase “self-government.” we are dealing with a “whole nation itself assembled” or with its representatives. the laws that have been emanated flow, jefferson said, from the “will of the society.” every generation is “independant.” they, the living generation, are the sole legal subject that can manage the earth and property “as they please.” no other subject is allowed to do that. not classes; not even laborers. the living are the sole “masters,” as jefferson made clear, “of their own persons, and consequently may govern them as they please.” tj to isaac mcpherson, aug. , ptj, retirement series, : - . tj, the batture at new orleans (published as the proceedings of the government of the united states, in maintaining the public right to the beach of the missisipi, etc., ), writings of thomas jefferson, : - . on jefferson considering property of land sanctioned by the “laws of civil society” for the en- couragement of industry (also shorn of any moral reprobation), see tj to thomas earle, sept. , writ- ings of thomas jefferson, : - . tj to james madison, sept. , ptj, : - , passim. on the class conflict afflicting english, not american society, see tj to thomas cooper, sept. , ptj, retirement series, : - . i will return to this letter shortly. itinerari thomas jefferson on private property obviously, the “will of the majority” can rarely be obtained “fairly and without impediment.” the people cannot easily “assemble themselves.” the representation may be “unequal and vi- cious.” factions may “get possession of the public councils.” “personal interests” lead represen- tatives “astray from the general interests of their constituents.” but these hindrances only prove that laws should be of limited duration, not that the living whole has no real and absolute authority. against the true and living community, no part, no class, no group should consider itself “inde- pendant.” the issue of property and its relationship to labor must be assessed within this communitarian framework. it would be an open betrayal of the living generation if a part decided on its own to pursue its interests, however noble and just they might appear. similarly, redistributing and so- cializing property would not necessarily be an act of justice made in the interest of the whole com- munity. jefferson, in effect, was against redistribution. “to take from one, because it is thought that his own industry and that of his fathers has acquired too much, in order to spare to others, who, or whose fathers have not exercised equal industry and skill, is to violate arbitrarily the first principle of association, ‘the guarantee to every one of a free exercise of his industry, and the fruits acquired by it.’“ in a similar spirit, he also wrote: “the first foundations of the social compact would be broken up were we definitely to refuse to it’s members the protection of their persons and property, while in their lawful pursuits.” tj, prospectus introducing tracy’s treatise on political economy, appended to tj to joseph milligan, april , writings of thomas jefferson, : ;

… most of the laboring class possess property, cultivate their own lands, have families, and from the demand for their labor are enabled to exact from the rich and the competent such prices as enable them to be fed abundantly, clothed above meer decency, to labor moderately and raise their families.” jefferson’s utopianism rested in the conviction that america was in excellent shape, and that only details had to be readjusted. while fancying “a cordial fraternization among all the american nations” old jefferson openly yielded to a biblical dream: “the lion and the lamb, within our re- gions, shall lie down together in peace.” after achieving the presidency and accomplishing the “revolution of ,” jefferson had already confessed his conviction that “the storm we have passed through proves our vessel indestructible.” this kind of utopianism, insisting on uncritical optimism and emphasizing “our” greatness, made jefferson in some way blind to the ordeal of american under-classes, natives, enslaved individuals, women, or laboring children. he did not have the same perception we have about the fact that in america rights were actually violated. locke, second treatise, chapter , section . on jefferson’s theory of property as essentially locke’s, see griswold, “agrarian democracy of jefferson.” i consider the following passage a stunning criticism of every rousseauian perspective: “he who is permitted by law to have no property of his own [like slaves, for example], can with difficulty conceive that property is founded in any thing but force.” tj to edward bancroft, jan. , ptj, : . on the rich being “few, and of moderate wealth,” see tj to thomas cooper, sept. , ptj, retirement series, : . on “our people,” not needing “to labor sixteen hours in the twenty-four,” see tj to samuel kercheval, july , works of thomas jefferson, : . tj to thomas cooper, sept. , ptj, retirement series, : . tj to william short, aug. , writings of thomas jefferson, : - ;

and which leaves to everyone else the like advantage. … if there be a government then which prides itself on maintaining the inviolability of property; which provides that none shall be taken di- rectly even for public use without indemnification to the owner, and yet directly violates the property which individuals have in their opinions, their religion, their persons, and their faculties; nay more, which indirectly violates their property, in their actual possessions, in the labor that acquires their daily subsistence, and the hollowed remnant of time which ought to relieve their fatigues and soothe their cares, the inference will have been anticipated, that such a government is not a pattern for the united states. for lord kames and for his followers as well, including hume and adams smith, property was more than just material objects. it was a part of one’s sense of self. without property, persons were missing an important dimension of their personality together with their grasp on the society around them. they had little or no chance to be publicly acknowledged. as arthur herman has noticed, in eighteenth-century english “property meant the same as propriety: those things that are proper to me, and to me alone. … to own things is in fact to own myself. property makes me a whole and complete human being.” besides its material connotation, property was also a condition of the mind, the best intel- lectual device to counteract “dependence.” to some extent, it was an anthropological category, dependent men being those who have lost propriety, namely, honor, agency, control, position, and affiliation. jefferson may have felt sorry for all those who, for historical or biological reasons, fell into the category of the un-propertied. he also honestly sought to enlarge the opposite group. but, realistically, he expressed no moral embarrassment, let alone indignation or desperation, that an increasing number of american individuals without propriety, the “private,” would never be in- cluded in the american community. instead of showing desperation or indignation, jefferson found refuge in his conservative utopia. this was most likely his way to compensate for the reality that virginia also was dramat- ically changing. before the revolution, almost every white male had property (in both senses of the word) and was qualified. every male was the center of a little universe. in the colony, land kammen, “rights of property,” . madison, “property,” the national gazette, march . herman, scottish enlightenment, . itinerari maurizio valsania ownership had been widespread. perhaps as many as eighty or ninety percent of white males either had sufficient property of their own or could claim protection from a propertied friend or relation. the trend in post-revolution virginia was toward an increase in the white un-propertied popula- tion, landless and dependent. the sheer number of virginians was advancing at a steady and dis- quieting pace. although it was not immediately a natural right, jefferson regarded property as a fundamental tool. it was an instrument, a social invention, to “augment” the self, notably, to increase individual efficacy. it was an effective means for getting a foothold in reality while winning acknowledgement from other fellows as a man of position. bibliography banning, lance ( ), jefferson and madison: three conversations from the founding, rowman & lit- tlefield publishers, lanham, md. burstein, andrew, and nancy isenberg ( ), madison and jefferson, random house, new york. conklin, carli n.

journalism history : (fall ) roger p. mellen for years, historians have written that thomas jefferson and his fellow patriots brought a second printer into the colony of virginia so that their radical messages could be heard. by examining newspapers and other evidence from the critical period around the stamp act of - , this article uncovers flaws in that interpretation and attempts a better under- standing of what happened and how that influenced the development of a free press. jefferson was not directly involved in procuring a printer, but new print competition did bring substantial changes to the relationship among the printer, the government, and readers. broader civic discourse spurred by commercial competition helped to develop new revolution- ary ideals, including the concept of a constitutional protection for a free press, which ultimately was expressed in the first amendment. roger p. mellen is an assistant professor in the department of journalism and mass communications at new mexico state uni- versity. this article will be appearing in an ed- ited form as a chapter in the origins of a free press in prerevolutionary virginia: creating a culture of political dissent, which will be published soon by the edwin mellen press. thomas jefferson has long been credited with bringing a printer to virginia in , introducing print competition to a colony that until then had only one printing press, which was controlled by the royal government. “until the begin- ning of our revolutionary dispute, we had but one press,” he said, “and that having the whole business of the government, and no competitor for public favor, nothing disagreeable to the governor could be got into it. we procured [william] rind to come from maryland to publish a free paper.” thus, just as parliament’s hated stamp act threatened the printers’ very livelihood, a new printer was encouraged to open a second shop in williamsburg, bringing competition to that field and a second newspaper to virginia for the first time. this was an important watershed for the culture and the government of the colony because it signified a shift in the power structure: control of public messages began to relocate from the royal government to the consumer marketplace. this was a transformation that had a major impact on civic discourse in the colony. despite such significance, the reasons behind such a change and the relevance of it have often been misunderstood. it has widely been accepted that jefferson was responsible for bringing such print competition to virginia and direct “patriot” influence was behind a freer and more open press. this jefferson connection has been repeated continually by histori- ans as has early print historian isaiah thomas’ contention that jef- ferson confirmed this in a letter written to him. this article shows that both these assertions are apparently erroneous and attempts to reach a better understanding of why these claims were originally made, how they were constantly repeated, and the larger signifi- cance of the motivations behind and relevance of such a change. print competition came later to virginia than it did to the northern and mid-atlantic colonies. in virginia, this altered the relationships among printers, the government, and the readers. this study finds that as the role of print expanded and evolved, it had substantial long-term influence on civic discourse, culture, and the radicalization of politics. each of the two printers responded to market pressure and the realities of new competition, both be- coming less an official mouthpiece and more a voice of dissent, which enabled the transition from a deferential society to one that openly questioned the government. as the importance of an open- thomas jefferson and the origins of newspaper competition in pre-revolutionary virginia journalism history : (fall ) and critical press became more evident to residents, the practice of civic discourse became visible in the public prints. this research will discuss these changes and how they influenced the press in the important colony of virginia on the verge of the revolution. thomas was intimately involved in the world of print and printers in the early revolutionary period in america and has left later historians with important details as well as misconceptions. he was the first writer to seriously look at the history of printing in the united states, and he also was an early printer and the founder of the american antiquarian society. in , he published the history of printing in america, which contained considerable re- search plus his intimate knowledge of the early days of printing in the colonies and the republic. as susan macall allen not- ed in her dissertation on the stamp act and colonial printers, thomas’ eye- witness account provided invaluable de- tails regarding american printing, and, “its accuracy has been trusted by schol- ars, and it is often cited as the authorita- tive source.” she also wrote his work “has occasional errors of fact that subsequent scholars have pointed out.” his chapters on virginia and maryland were much shorter than his entry on massachusetts, which was not only where he lived and worked but was where printing in brit- ish america originated. he observed, “as there was but one newspaper published in virginia in ; and but one press in the province, which was judged to have an undue bias from the officers of gov- ernment, a number of gentlemen who were desirous of having a free and unin- fluenced gazette” encouraged a second printer, william rind, to come to wil- liamsburg. he added that a letter to him from jefferson confirmed this because he said he was involved in procuring rind. other historians have repeated these claims endlessly. arthur schlesinger, the elder, noted in that the stamp act was a burden largely for those who were most capable of stir- ring up resistance because they were the most vocal and influential members of society—clergy, lawyers, merchants, and printers. ev- ery newspaper had to carry a minimum of a halfpenny duty with a two-shilling tax for each advertisement. worse still, the stamp act required importing expensive paper instead of using locally pro- duced material. thus, newspapers were changed by this new tax, he suggested, from merely transmitters of information to opinion makers. he quoted from david ramsay’s book, the history of the american revolution, which said printers, who generally favored liberty but were more interested in profits, universally opposed the tax: “a stamp duty, which openly invaded the first, and threatened a great diminution of the last, provoked their united zealous op- position.” while schlesinger repeated thomas’ claims, he also sug- gested the new, second printer in virginia was not influenced by the governor, and in the years ahead, both newspapers supported the patriot cause. in , historian stephen botein concluded printers were more businessmen, or “‘meer’ mechanics,” than revolutionaries, and he wrote the stamp act profoundly changed their business. printers’ normal, cautious tendencies to stay out of controversies were overridden by their financial interest. the standard viewpoint had been that a free press meant presenting both sides while staying out of extreme disputes that might have alienated any customer. this new tax not only threatened their livelihood but political writing be- came a hot seller. most printers, he suggested, abandoned neutrality and chose sides, the majority opting for the patriots’ position. with printing limited to one government-sanctioned press, there could be no real press freedom. as book historian hugh amory noted in , printing was reflective of the power struc- ture of the colony within which it existed. in puritan new eng- land, about which he was writing, printing was initially licensed and sanctioned, serving rather than chal- lenging the power structure. it was the same when the press first came to virgin- ia. by the s, the pressures of trade and merchandising altered the function of a press from merely a duplicator of of- ficial governmental and religious works to one of commercial output. with a second press and consumer pressure, the character of printing and the idea of a “free press” was transformed because a wider range of content freed print to function as a medium for the “diffusion of useful knowledge.” t.h. breen theo- rized in that a rising marketplace and a consumer revolution was an im- portant preface to political change, and newspapers, as part of this increased consumption, helped expand civic dis- course. as historian jack greene wrote in his exploration of the shifting of power in the southern colonies, govern- ment support for a printer was crucial in such colonies as virginia before a strong, commercial economy developed. he sug- gested the royal governor had a great deal of control over what was printed prior to , and he repeated the claim that jefferson was involved in changing that situation. more focused on virginia and its printers, laurie godfrey wrote in that the two virginia newspapers had an “authori- tarian” stance throughout this period, not shifting to a more “liber- tarian” revolutionary ideology until three to six months before the revolution. she concluded this ideological shift in the press hap- pened later in virginia than in the middle and northern colonies, suggesting this was because of the colony’s extremely close trade and ideological ties to england and a social structure in which the plantation gentry were considered the natural rulers. her analysis utilized fred s. siebert, theodore peterson, and wilbur schramm’s four theories of the press and downplayed some obvious shifts in the presses’ viewpoints in the s. however, she did get correct many of the important details that had eluded more prominent historians, and she observed that the character of the press in vir- ginia changed after the mid-eighteenth century. from the beginning, the government in colonial virginia tightly controlled the press, and there was no real freedom of expression. from governor william berkeley’s warning to his superiors, the commissioners of trade and plantations in london, about a troublesome press in , to governor thomas culpeper’s expulsion of a printing press for being unlicensed in “in , historian stephen botein concluded printers were more businessmen, or “‘meer’ mechanics,” than revolutionaries, and he wrote the stamp act profoundly changed their business. printers’ normal, cautious tendencies to stay out of controversies were overridden by their financial interest.” journalism history : (fall ) , to the eventual welcoming by the royal government of a press in , government income and control were the key in- fluences. thus, the press in colonial virginia began as a royally sanctioned and controlled institution, which was paid for and li- censed by the government in power. as both amory and richard d. brown noted, knowledge was power, and in the early colonial period, information was in the hands of governmental and ecclesi- astic authorities. not until a second printer existed, and commer- cial competition began, could there be a free press. the first printer, william parks, began his newspaper publish- ing with an overt recognition of the limits of press freedom and announced a need to defer to those in power. the first issue of the virginia gazette in had an explanation of this in the “printer’s introduction;” by the liberty of the press, we are not to understand any licentious freedom, to revile our governors and magistrates; to traduce the establish’d laws and religion of our country; or any attempts to weaken and subvert by opprobrious writings that sacred respect and veneration which ought always to be maintain’d for authority, and persons in authority such deference was necessary for a printer in early virginia. without any large urban community or a strong commercial econ- omy, all of the southern colonial printers before counted on a government salary as part of their support, but it was not always clear who in the government controlled the printer. the house of burgesses in virginia voted on the printer’s salary, but it also had to be approved by the royal governor and his council. greene suggested that despite the lower house’s control of money, the gov- ernor was generally able to exert the most censorship, at least until the s. however, former governor alexander spotswood wrote printer parks in , complaining that it was the burgesses who maintained a tight control over the content of printed matter. he prefaced what eventually made it into print: “if his worship will permit you to publish in your news paper, this answer.” this was a reference to john randolph, speaker of the house of burgesses and treasurer for the colony, with whom spotswood was having an open dispute over the spending of public money dating back to his administration. as greene observed, the assembly struggled against the royal governor’s authority, and control of the press was an important part of that power structure. this control over the content of the newspaper by the gov- ernor again became apparent in , when a virginia resident turned to the newspaper in the neighboring colony of maryland to complain, “the press in this colony [virginia], either through particular inclination, or some other cogent bias, in the proprietor of it [william hunter, parks’ successor], is, in many instances, shut against us.” the virginia governor had accused the burgesses of neglecting the safety of the colony by not taking any action against french aggression. to counter that accusation publicly, the bur- gesses had to turn to the maryland gazette in annapolis. in con- trast, the few issues of the virginia gazette of that period still ex- tant show only mutual respect and deference between the burgesses and the governor. the williamsburg press appears to have been largely under the control of the governor at this point. as botein suggested, the colonial printer could little afford to offend power- ful individuals or groups with what he printed and often avoided controversy altogether. few issues of the newspaper published by hunter’s successor, joseph royle, still exist, but those that do were mostly filled with literary essays, news from europe, and debates over social practices. for example, a recently recovered rare issue from began with a letter declaring that oaths were sworn all too often without con- sidering the responsibility of making such a promise. two essays took a large portion of column space; one describing a conversa- tion between a master and his dog while the other was a farmer’s dream that led him to gold. both appear to have been an attempt to instill strong moral values in readers. several short items talked about new crops being raised in south carolina, clashes with the indians and the french in other colonies, and scientific advances to measure longitude. finally, future president george washington ran an advertisement in an attempt to find the owner of two run- away horses discovered on his plantation. little in this or other extant issues demonstrated a willingness by the printer to tackle controversial issues. accusations of control by the burgesses, rather than the gov- ernor, again surfaced in one dispute. the controversy over pay for the official church of england ministers in the mid- s brought accusations of censorship by the virginia printer. reverend john camm was forced to turn to the maryland press to print a pam- phlet in answer to comments by two burgesses that had been print- ed in virginia. apparently, printer royle was afraid of offending burgesses who were satirized in camm’s response: [i]f it should displease, would be taken as ill by this assembly, as if pointed directly at them; i am far from saying it would give them offence, nay, i think otherwise; however as there is a possibility in the case, it will be most prudent in me not to risk forfeiting their good-will upon such an issue, as i cannot but own myself a dependent upon the house of burgesses, and the public in general. i therefore return you your pamphlet. royle appeared to be more timid than overtly controlled. while camm argued that he should be able to use the press to tell his side of a story that had already been printed, he recognized thomas jefferson journalism history : (fall ) the printer’s editorial right: “i acknowledge as much prudence as you please, in the rule by which your press is conducted.” this view of the press demonstrated a theory of the press that it was not so overtly controlled by the government but instead the pri- vate printer had some discretion, which he needed to exercise with care. offending either the governor or the burgesses could threaten his government-printing contract, an important part of a printer’s income, which had to be approved by all branches of the colonial government. in , david rawson suggested that for a brief time, the virginia gazette opened its pages to increased local controversy, eventually leading to a reassertion of control by the governor just prior to the stamp act. printer hunter was ill and spent consider- able time out of the colony between and , apparently leaving his assistant, john stretch, in charge of his print shop, the newspaper, and the post office. according to a local resident who wrote hunter upon his return, the newspaper had a slightly more lively, local debate in that interim period, only to become more boring after hunter’s return. “tim pastime” sent a thirty-six page letter to the printer, addressing him as “demipostmaster, printer and linnen draper” (the latter appears to be a bit of cockney rhyming slang, perhaps insulting the newspaper business, as in “linen draper/newspaper”). the pseudonymous author suggested that because stretch, “that flower of beauty, and cream of all proportion, has left this colony . . . your publications are but sometimes little entertaining and, at every other time extremely dull” (from the context, the seemingly positive description of stretch was sarcasm). while presumably not printed in its entirety in the gazette, the letter recommended hanging it on a peg in the printing office where visitors could read it, suggesting that had been done before with other letters. this offers an interesting image of the printing office as a busy center of discourse and information beyond what printed material and post office business would offer. local residents stopped by, read letters not yet printed, and discussed the latest news. according to rawson, stretch was in charge of the newspaper for more than three years, and it offered more lively political debate under his stewardship. he suggested this resulted in governmental pressure on hunter and forced the reassertion of gubernatorial control over the newspaper. this is largely conjectural because there are few ex- tant copies of the virginia gazette from this time period to confirm the content biases suggested by this single letter. it was such control by the royal governors, however, that con-stantly frustrated more radical virginians and eventually led to action. in october , the maryland gazette printed a letter written anonymously to the virginia printer but never published in his paper. it accused williamsburg printer royle of deceiving read- ers and yielding to royal pressures. the annapolis newspaper pub- lished the letter with an added note by the author saying virginia did not have a free press “as the only one we have here, is totally engrossed for the vile purpose of ministerial craft: i must . . . apply to you . . . [b]old and honest assertor of the cause of liberty.” this insinuated not just gubernatorial control of the williamsburg newspaper but implicit bias in favor of corrupt ministers in eng- land. the more radical political element in virginia turned increas- ingly to the maryland press for distribution of its ideas, and this partly fulfilled its goals since the maryland paper had a substantial number of readers in northern virginia. in a virginia ga- zette, a “man of principle” wrote that while royle was the only vir- ginia printer, between and the press “was not renowned for its freedom,” and he alleged the governor was allowed to read the newspaper before it was circulated and actually censored it: if a counselor or a burgess was only squinted at in any thing sent to the press before this period, it was wither too low or too-------but if a governour was------ o horrible!—has it not been said that mr. royle owned a private license, and that a paper was constantly carried to a certain house in palace street [the governor’s palace] to be inspected before it could be seen by the publick? the author of this piece claimed royle acted as though he was dependent upon a license to print, and the governor was checking everything before it could be published. this view was of a press tightly controlled by the royal governor and described a press that was not suited to the needs of political allies (later referred to as the “patriots”) attempting to oppose official british colonial taxation policies. such a tightly controlled government press was a chal- lenge to the evolving concept of civic discourse and a free press. writers were constantly forced to turn to presses elsewhere to print anything critical of the british government or the local governor, and readers also had to look elsewhere for broader discourse. such censorship of the local press also, of course, could have been the result of several other reasons: the printer might have been more timid than others, his personal loyalties may have been closer to the british ministry, and it was always easier to print matter critical of one government in another jurisdiction, where the local gov- ernment was not the focus. whatever the reasons, local patriots found the printer too conservative to allow them to express their dissenting opinions. while it was often inferred that royal governor francis fau- quier kept tight control over the output of the press, he was popu- lar. a young jefferson, often a guest at the governor’s dinner table, later referred to him as “the ablest man who ever filled the chair of government in williamsburg.” fauquier followed an unpopular governor, robert dinwiddie, and was quick to form partnerships with leaders in the house of burgesses. in contrast to his prede- cessor, he had strong alliances with local leaders, including power- ful house speaker and colony treasurer john robinson. the colo- nists appreciated that fauquier sometimes did not obey instructions from his superiors in london and considered him amiable, just, and “moderate in power.” it is clear from the correspondence of fauquier to his supervisors at the board of trade that he closely monitored what was printed in the newspapers, often including copies of the virginia gazette and occasionally the maryland ga- zette in his letters to london. in a letter, fauquier noted the stamp act forced the shutting down of the virginia newspaper, and new print competition was on the way: from the first of november we have been without any newspaper till very lately. the late printer to the colony is dead, and as the press was then thought to be too complaisant to me, some of the hot bur- gesses invited a printer from maryland, upon which the foreman to the late printer, who is also a candidate for the place, has taken up the news paper again in order to make interest with the burgesses. the governor also noted that a second, competitive newspa- per was about to begin and would be in addition to the original virginia gazette, which was being published by alexander purdie, the foreman for the late royle. he suggested that it was the work of some of the more radical burgesses, who were unhappy with the old press because it was too willing to please the royal authority in the colony. as colonial opposition to british taxation policies journalism history : (fall ) gained ground, virginia readers who were not content with the local printer hoped that a new, competitive newspaper would allow for a more critical civic discourse. historians have generally agreed who was involved in this somewhat rebellious move to bring in an opposition printer. thomas claimed that jefferson wrote him: “until the beginning of our revolutionary dispute, we had but one press, and that having the whole business of the government, and no competitor for public favor, nothing disagreeable to the governor could be got into it. we procured rind to come from maryland to publish a free paper.” this claim of jefferson’s involvement has been repeated in many books, including those by schle- singer, philip davidson, sidney kobre, greene, and an anthology edited by ber- nard bailyn. numerous other works also have included the assertion that the former president wrote about this spe- cifically in a letter to thomas. in her dissertation, godfrey said it was extremely unlikely that jefferson was that deeply involved. she noted that at the age of twenty-two, he was likely to be merely a bystander in procuring a printer, and the widely repeated claim actually came from a letter that he wrote to someone else. she did not speculate about why he included himself by using the term “we” and why thomas might have claimed jefferson wrote that in a letter to him, nor did she recognize the significance of print competition on the ideological bent of the newspapers. because it was a minor point not central to her larger work, the argument was not completely researched and developed, and few have noticed her point. a deeper examination of the evidence confirms her doubts of the claim that jefferson was directly involved and that he wrote directly to thomas about it. this raises questions about memory and historical research, and it also helps explain the origins of print competition in the colony. when the provenance of the jefferson claim was cited, it was either directly from thomas’ influential history of printing in america or a secondary or tertiary source that took it from there. thomas wrote “a number of gentlemen who were desirous of having a free and uninfluenced gazette, gave an invitation to rind,” and he foot- noted it: “this fact is corroborated by the following extract of a letter to the author from thomas jefferson, late president of the united states, dated july, .” what godfrey and other researchers failed to note is that only in the second edition of his book did thomas claim jefferson wrote directly to him. the first edition merely noted jefferson wrote this in a letter, and the recipient was unidentified: “this fact is corrobo- rated by the following extract of a letter from thomas jefferson, esq. late president of the united states, dated july .” later editions of history of printing in america claim jefferson wrote the letter specifically to thomas, but the letter does not exist in either thomas’ extensive papers nor in jefferson’s papers, despite the fact that the former president kept copies of virtually all of his corre- spondence in this period. jefferson did write those words about the press being overly influenced by the governor and the procure- ment of rind, with only minor discrepancies of capitalization and abbreviation, to william w. hening the year before thomas’ book was first published. it is also known that hening wrote to thomas about another matter within a year of jefferson’s letter. in a copy of the first edition of history of printing in america that thomas notated for a revised second edition, he wrote “to the author,” in- dicating the former president’s letter was to him, and that is how it ended up in the subsequent edition of the book. it seems prob- able that either thomas stretched the truth to make the point that a former president of the united states corresponded with him, or that time and old age had distorted his memory (he was at least sixty-one years old and possibly as old as eighty-three, when he made that notation). what is remarkable is that this claim, rea- sonably easy to double-check, has been passed on by other historians for more than years. furthermore, the suggestion that jefferson was a key player in the recruit- ment of the new printer does not stand up. as godfrey noted, jefferson was only twenty-two years old and not yet a mem- ber of the house of burgesses. before rind would have left his lucrative part- nership in annapolis, it would have been necessary to offer him either cash or a promise of becoming the official printer of the colony, which would guarantee him an income. according to jefferson’s autobiographical draft, he was a mere law student and not yet a practicing lawyer in . however, he apparently later had some type of relationship with rind’s competitor, printer purdie. while he was writing the declaration of independence at the continental congress in philadelphia in , a friend wrote to him that purdie promised to pack up jef- ferson’s books to be shipped to him. thus, it appears that when jefferson wrote “we procured rind,” he simply meant to include himself among his political associates in williamsburg, who were later identified as patriots, including some who were senior to him and in a better position to do the actual procuring. it is reasonable to conclude that some of the “hot burgesses” to whom the governor referred, and very possibly the lee family specifically, had a greater involvement than jefferson in recruiting a new printer. when rind moved to williamsburg, he lived in and worked out of a brick house on duke of gloucester street that be- longed to philip ludwell iii, the uncle of the lee brothers: thomas ludwell, richard henry, francis lightfoot, william, and arthur. richard henry lee and arthur lee contributed many essays to rind’s newspapers, and in , william lee inherited “the man- sion” in which rind lived. edmund randolph, who was a young contemporary in , described a new group of burgesses at the time of the stamp act, who likely were the governor’s “hot burgess- es.” he suggested that the new “upper counties,” farther from the old power base of the james river, were supplying burgesses who no longer displayed the traditional “fortune, rank, and perhaps fashion,” and he mentioned specifically patrick henry, john flem- ing, and george johnston. later randolph lauded the oratory and patriotism of richard henry lee, whom godfrey included in the group. these men supported henry’s resolves against the stamp act and later became leading virginia supporters of the american revolution. the eventual selection of rind as the official “public printer” of the virginia colony was a disputed one. in november , “the suggestion that jefferson was a key player in the recruitment of the new printer does not stand up. as laurie godfrey noted, jefferson was only twenty-two years old and not yet a member of the house of burgesses.” journalism history : (fall ) four printers, or groups of printers, petitioned the burgesses for the appointment. purdie and john dixon were the successors to the former public printer, the deceased royle, and were a likely lead- ing candidate. however, their combined petition received only ten votes in the house of burgesses, while robert miller had seventeen votes, william stark got nineteen votes, and rind had a majority with fifty-three votes. the governor and his council later agreed, despite the fact that the royle/purdie and dixon press had a his- tory of subservience, and rind was paid £ a year for his official printing. it is clear that someone with a great deal of influence in the government—which jefferson did not yet have—lobbied hard to get rind this appointment. rind’s arrival and election as official printer meant there was now competition for local printing in virginia, and that had an immense impact on the printed material available in the colony. two printing houses now operated in williamsburg. rind imme- diately undercut his rivals’ newspaper sales price, from shillings for a yearly subscription to shillings, pence. the new paper was originally called, rind’s virginia gazette, but soon the printer removed his name from the title, leaving the colony with two news- papers with the exact same name. the first issue of rind’s paper boldly stated his intent to run “a well conducted news-paper,” which he noted was essential just then, “especially at a crisis, which makes a quick circulation of intelligence peculiarly interesting to all the american colonies.” the only extant copy of this issue has an interesting editorial insertion penned in, apparently by the original owner, noting this was the first well conducted news- paper to be printed in the colony: “and the first that has ever been established in this province.” while the writer is unknown, the comment demonstrates the hope of virginia residents of to have a better-run newspaper that would be freer to publish criti- cism of the government. rind claimed his newspaper would be, “open to all parties, but influenced by none.” the original virginia gazette was quick to join the competitive fray, matching the new competitor’s moves and gaining for itself a reputation as a “free press.” now published by purdie, who was soon joined by dixon, they quickly matched the lower price and announced a new, open press policy before rind’s newspaper even came out: “[m]y press shall be as free as any gentleman can wish or desire; that is, as free as any publick press upon the continent.” a few months later, two writers arguing opposing sides of an issue agreed on one thing: the press run by purdie and dixon was now well run. such freedom of the press “is [a] matter of rejoicing,” and “you, sir, have behaved yourself as the director of a press ought to do.” however, these writers’ praise was for both presses. a notice in purdie’s paper acknowledged that only with real competition, only with at least two newspapers, could a free flow of information be sustained. with the loss of the government subsidy, purdie was in danger of being forced out of business, and he pleaded with the “friends of liberty” to help keep his newspaper and print shop in business: “[w]e have reason to believe it the almost universal desire that there should be two presses maintained, for the security of freedom to one or both.” they requested their readers to con- tinue their subscriptions with the original virginia gazette. it was believed that only with two presses, only with competition, could the press be free. for a short period of time, rind included a claim that his was the official newspaper, demonstrating that this was a confus- ing transition period for the press. the masthead of his version of the virginia gazette, beginning early in , included the claim, “published by authority,” which was just months after his appoint- ment as the “public printer.” this phrase had often been used in english papers since the days of licensing to indicate an offi- cial government imprint, and it was on the masthead of the first regularly published british-american newspaper, john campbell’s boston news-letter in , but it had never before been used in virginia. in a letter published in the other virginia gazette, “a man of principle” wrote questioning the “authority” claim: “several of your readers are very solicitous to know what authority you have for publishing a paper now, more than formerly. some, i suppose of the most intelligent, allege that because you have had the good fortune (for certainly you cannot ascribe it to anything else) to be chosen publick printer, that gives you an exclusive privilege.” the author pointed out that anyone who wished could publish a newspaper and call it the virginia gazette. this demonstrated the confusion of the period as printers shifted from functioning as official government printers to public businesses. while rind still had a lucrative government contract, the profit center had shifted to where satisfying the public was one key to financial success, and by july, he had dropped from his masthead the claim that he pub- lished by authority. thus, the newspaper in virginia had moved from a quasi-governmental source to one where public opinion and marketplace competition was paramount. the stamp act controversy offered a contrast between the earlier restricted press with the competitive press exercis-ing greater freedom. when the british tax enraged the colonists, royle failed to print the stamp act resolves, which was passed just down the street by the virginia house of burgesses al- though other newspapers across the colonies published this heated reaction to parliament. instead, his paper called on the assembly to help enforce the tax and warned of “the consequences if you should suffer a confirmed disobedience of this act of parliament to take place.” this was quite different from reports published in the neighboring colony of maryland and also in sharp contrast to what was printed in both versions of the virginia gazette in the next year. the original virginia gazette, now published by purdie, contained an item that referred to the stamp act as a flagrant viola- tion of the british constitution and called the idea of virtual rep- resentation in parliament a “despicable subterfuge.” competitor rind’s newspaper ran two letters from the radical boston gazette, “letters from a farmer” and “the monitor’s letters,” which was a virginia-based attack on the stamp act. the latter admonished britain for attempting to enslave the american colonists, suggest- ing “that though we are a weak people, yet the principles of liberty fully infused into us, will render it impossible to enslave us.” the content in the pages of the two gazettes reflected a sub- stantial change. with considerable coverage of the stamp act crisis and later taxation issues, neither newspaper displayed the former tendency to buckle under royal pressure. the two gazettes ran more articles critical of the colonial government, parliament, and the british ministry, including stories that would not have been printed a few years earlier. each paper also covered the scandal fol- lowing the may death of the powerful virginia treasurer and speaker of the house of burgesses, john robinson, who it was dis- covered had illegally loaned , pounds of public money. one planter complained that “very large sums of the public money have been misapplied” and recommended that in the future, the offices of treasurer and house speaker be held by separate individuals. he noted that his participation in this civic debate “would not have been in my power without the benefit of a free press.” journalism history : (fall ) a related incident displayed the new power to criticize the elites in the public prints. both newspapers published letters ques- tioning the actions of several of the colony’s chief justices following the public killing of robert routlidge by colonel john chiswell in june . according to a detailed newspaper description, an angered but sober chiswell stabbed his unarmed and drunk friend through the heart with his sword. both gazettes eventually ran articles not just about the slaying but about the subsequent actions of the accused killer, including the fact that three of the highest judges in virginia had released him from jail. an anonymous letter noted the original court refused to release the accused murderer on bail and remarked that chiswell was a well-connected member of the colony’s elite (in fact, probably one of those to whom robinson had lent public money). this article questioned the legality of the judges’ release of the accused: “[b]efore he was delivered to the keeper of the publick prison, the judges of the general court, out of sessions, took him [chiswell] from the sheriff who conveyed him from cum- berland, and admitted him to bail, with- out seeing the record of his examination in the county or examining any of the witnesses against him.” another letter writer, who called himself “dikelphilos,” suggested that because of his social stand- ing, “the murderer was treated with in- dulgence and partiality inconsistent with our constitution, and destructive of our security and privileges.” the fact that both newspapers made public the details of this controversy, and included critical comments regarding the actions of the colony’s elite, was something that would not have happened a few decades earlier. thus, by , new commercial competition had led to less gov-ernment control and a freer fo- rum for civic discourse in both virginia newspapers. no longer was there only one press in virginia, and no longer could the governor control the press. power was shift- ing from the governor to the burgesses, and newer, more radical burgesses were gaining in influence. politics in virginia was frac- tionalizing, and soon that was reflected in the media of the time. after a second press began printing in the colony, leading politi- cal elites, the parliament, and the british ministry were subject to criticism on the pages of the virginia newspapers. as carl briden- baugh wrote in his essay about violence in virginia, purdie “completely revised the former policy of the newspaper” and from then on, the residents of virginia were “served up . . . what they had never before experienced, the sensations and sensationalism of a free press.” he suggested that the new freedom of the press brought excesses and sensationalism, but the newspapers also now put the feet of the wealthy to the fire. an anonymous writer wrote of the changed newspapers in mock-biblical fashion: “party shall menace party, and dunce shall enflame dunce, and the gazettes of purdie and of rind shall contain wonders . . . and much paper [will] be wasted, and words shall lose their meaning.” obviously, not everyone was happy with the political controversies now being openly publicized in the newspapers nor with the less sophisticated tone of the letter writers. both newspapers appeared to be directing their content to the same, somewhat middling-to-elite audience with the same political bias. one contributor noted that what was now being printed in the two papers no longer had the high standards of the past. “dikel- phios” requested that potential authors should examine carefully their abilities, and “they would not usher into the world sentiments which are neither useful nor entertaining.” this apparently was an expression of dissatisfaction with the contributions to both papers from those further down the social scale. there was no longer an obvious elite bias to the papers’ content; there were no more latin verses, fewer classical references, and more common pseudonyms, such as “a farmer,” or “tit for tat.” sales and satisfied custom- ers had become more important to the printer than pleasing the governor. as botein wrote, the business phi- losophy of the printers had to change with the times, and it was now political material with a patriot slant that was the best seller. newspaper circulation in the colonies also had increased, and political writings became popular. both print- ers featured a patriot viewpoint in their papers with no noticeable difference in the bias or content, including the adver- tisements. as godfrey concluded, “rind and purdie . . . provided the same voice for the community.” one might add that the readers of the two newspapers also appeared to be the same, geographically and economically. what she did not rec- ognize was that this was not only because of royle’s death or the direct influence of a new political force. it was also because of the new commercial pressures, requir- ing both printers to respond to the needs of the customers. thus, the myth of jefferson corre- sponding with thomas, confirming that he invited rind to bring his printing press to virginia, offers a patent example of question- able memory, misinterpretation, and a weak historical method. human recall is not as precise as is sometimes presumed, and lan- guage is often ambiguous. thomas falsely claimed the former presi- dent wrote to him regarding the virginia printer. however, this did not crop up until later in thomas’ life and only then in his note for the second edition of his book. old age may well have begun to cloud his memory, or it may have been a case of false bragga- docio that a former president had corresponded with him. jeffer- son’s actual statement, written in a letter to hening rather than to thomas, was misinterpreted by thomas and following generations of historians. “we procured rind” did not mean that jefferson was a leading actor as countless historians have inferred from the line. as a twenty-two-year-old student, he did not have the means to arrange rind’s election to the public printer post. he noted in his own autobiographical draft that at an incident during that same time (the passing of the stamp act resolves in williamsburg) he was merely a young observer: “i was yet a student of law in wmsbg. i attended the debate however at the door of the lobby of “by , new commercial competition had led to less government control and a freer forum for civic discourse in both virginia newspapers. no longer was there only one press in virginia, and no longer could the governor control the press. power was shifting from the governor to the burgesses, and newer, more radical burgesses were gaining in influence.” journalism history : (fall ) the h. of burgesses.” it is more likely “we” either meant “we, the people of virginia,” or was a reference to the group of more radical politicians in the colony who later supported the patriot cause. it was a group with whom jefferson was to eventually take a leader- ship role. for nearly years, authors have repeated thomas’ story— even elaborated on it—apparently without confirming its verac- ity. davidson, in his important work, propaganda and the american revolution: - , cited no source for his statement that “thomas jefferson, dissatisfied with the old gazette, now ed- ited by alexander purdie and john dixon, brought william rind from maryland, and the second virginia gazette was begun.” kobre, a venerable journalism historian, also was certain of jefferson’s involvement: william rind’s third [sic] virginia ga- zette indicated the change in the social forces, for thomas jefferson backed rind because he believed the virginia gazette, which was then being published by alexander purdie and john dixon, was too closely tied to england. he considered that it was not representing the colonial cause with any strong determination and belief. he secured william rind from annapolis and rind’s virginia gazette began in williamsburg in may, . since kobre cited no source, it is un- clear how he determined jefferson’s rea- soning in such unlikely detail. influential historian schlesinger cited thomas in a article—“thomas jefferson and his friends persuaded william rind . . . to settle in williamsburg”—but the jeffer- son connection was not repeated in his book on the subject of colonial newspa- pers and the revolution in . more recently, other prominent historians con- tinued the error. greene cited briden- baugh when he wrote of the jefferson connection, and an article by robert weir in bailyn’s and john hench’s book on the press and the american revolution noted that the new printer “had come to williamsburg at the invi- tation of thomas jefferson and some other leading men.” while such prominent historians apparently did not see the weakness in thomas’ attribution, godfrey’s dissertation raised serious questions about jefferson’s involvement. however, it was not a major focus of her work, she apparently did not publish her findings, and she never developed the reason for the errors. this story of how one person’s flawed personal memory be-came part of the historical record holds warnings for histo-rians. too often they take the work of others at face value, without verification, because it is nearly impossible to double-check everything. they constantly build their work on the foundations of prior historians without often enough digging to verify facts, and thus errors large and small often multiply. as alfred young ob- served in , personal memory shifts over time, and historical memory can be far from perfect. going beyond questions of memory and accuracy, the situa- tion in virginia reveals much more about the evolution of print— and of press freedom. the character of the newspapers in the col- ony changed as competition came to williamsburg. from being a single newspaper that several times was accused of censorship in favor of the british ministry, depriving the virginia citizens “of that great support of freedom, the liberty of the press,” the com- peting gazettes now openly published controversy. a year later, in , another reader proclaimed “the press, one of the princi- pal handmaids of liberty, is become a free channel of conveyance whereby men may communicate their sentiments on every subject that may contribute to the good of their country.” another letter directly questioned the official actions of the colony’s supreme judges in their han- dling of the routlidge murder: “i ask, whether this act of the three judges of the general court be legal.” the causes of this radical transfor- mation of the press were more complex than simply jefferson or other patriots importing a new printer to publish a newspaper with more radical sentiments. new competitive pressures that accom- panied an emerging consumer economy brought a change in power and domina- tion. government control dramatically lessened, and marketplace pressures be- came paramount, which were necessary precursors to both a second printer and a more open press. as amory wrote, a single sanctioned printer could not run a truly free press: “the first step toward that distant nineteenth-century goal [of a free press] was often the advent of a second press.” as breen theorized, such marketplace choices began to erode co- lonial power structures, and a new “con- sumer public sphere” developed. news- papers were an essential driver, supplying substance and expanding this new dis- course: “everywhere americans reached out to each other through the channel of print.” as botein noted, colonial print- ers were forced to abandon their cautious approach, attempting to please all sides, as the stamp act threat- ened their livelihood. just as in the other colonies, virginia printers began to take a stand against british policies. thus, the virginia press became freer, more open to a wider range of opinions, including those critical of powerful members of government. quotations from john wilke’s radical newspaper, the north briton, appeared in rind’s gazette. dissent was printed openly, even harsh words written by those farther down the social scale aimed at the once-untouchable elites. for example, “an en- emy to hypocrisy” began his letter to the newspaper with a disclaimer of his abilities, yet he went on with a thinly disguised attack on colonel richard henry lee, calling him a rogue. the new competition in the newspaper and overall printing business in williamsburg assured a broader public of more outlets for wider viewpoints. the new printer did not provide the only open press, however. the older press, now run by royle’s successors, proved just as open to the faction that eventually became the patriots, run- ning stories about the sons of liberty and attacking the stamp “this story of how one person’s flawed personal memory became part of the historical record holds warnings for historians. too often they take the work of others at face value, without verification, because it is nearly impossible to double-check everything. they constantly build their work on the foundations of prior historians without often enough digging to verify facts, and thus errors large and small often multiply.” journalism history : (fall ) act as illegal. governmental pressure no longer reigned supreme. civic discourse in the colony of virginia had broadened and be- come more radical. such new discourse and the economic competition that spurred it have implications worthy of further development by to- day’s historians. the new press freedom and the public recognition of the importance of such broader civic discourse led to the flow- ering of an important new concept in pre-revolutionary virginia; the newly declared independent state’s declaration of rights in contained the first constitutional protection for a free press. article twelve declared, “that the freedom of the press is one of the greatest bulwarks of liberty and can never be restrained but by despotic governments.” this idea emerged directly from the public recognition that such open discussion was essential to a republican government, and such discourse was impossible when a powerful and potentially corrupt government could control the press. just days before this first free press clause was written, “civis” was lob- bying in the virginia gazette for recognition of the importance of a free press, stating, “liberty of the press is the palladium of our liberties,” and while free “speech is a natural right . . . printing is a more extensive and improved kind of speech.” the new civic discourse spurred the recognition of the im- portance of a free press, leading directly to the free press clause in virginia’s declaration of rights, and that—both directly and indirectly—inspired the free press clause in the first amendment to the united states constitution. other states followed virginia’s example and guaranteed a free press in their own constitutions, and when james madison wrote his draft of the bill of rights in , he worked from virginia’s example. the founders of this nation realized that only through a competitive, unfettered, and potentially annoying free press could a powerful government be balanced in the public interest, and they attempted to guarantee a free press by stating unequivocally, “congress shall make no law . . . abridging the freedom of speech, or of the press.” notes quoted by isaiah thomas, the history of printing in america, with a biog- raphy of printers, nd ed.

cosgrove, joan dipalma, douglas katz, and thomas kowalski ,* abstract background: acinar cell cystadenoma is a rare pancreatic cyst that has been described in several case reports. this lesion may be incidental or asymptomatic, occurs predominately in females, and has a mean age of onset in the fourth decade. case presentation: a previously healthy -year-old male presented with abdominal pain. he was found to have a pancreatic cystic lesion on ultrasound and cross-sectional imaging. his diagnosis remained uncertain de- spite additional analysis, including endoscopic ultrasound with fine-needle aspiration. the patient underwent successful laparoscopic excision for definitive diagnosis and management with an unremarkable postoperative course. he was diagnosed with a multilocular acinar cell cystadenoma. conclusion: acinar cell cystadenoma is a rare pancreatic cyst whose true malignant potential is unknown. although there are no formal recommendations for post-operative monitoring and the true risk of recurrence is unknown, we recommended every other year magnetic resonance imaging/magnetic resonance cholangiopancreatography for postresection surveillance for this patient due to the theoretical risk of recurrence with malignant transformation. key words: acinar cell cystadenoma; pancreas; pancreatic cyst background incidental pancreatic cystic lesions are becoming increasingly common with more widespread use of cross- sectional imaging. pancreatic acinar cell cystadenocarci- noma and acinar cell cystadenoma (aca) account for < % of these lesions. acinar cell cystadenoma is a rare pancreatic cyst that has been described in several case re- ports. – aca typically arise from a background of normal pancreatic parenchyma and may be focal or diffuse in dis- tribution. aca may be unilocular or multilocular, with larger locules harboring internal septations. unilocular aca are predominately lined by well-differentiated acinar epithelium without atypia and scattered ductal cells, whereas patches of ductal epithelium within a background of acinar epithelium are more typical of multilocular aca. acinar cell cystadenoma occurs predominantly in fe- males ( – % female), with

cancer volume . , doi: . /crpc. . .nco case reports in pancreatic cancer remaining hepatic function panel, complete blood count, lipase, and amylase were normal. an abdominal ultra- sound suggested a cystic structure medial to the left kid- ney with thickened internal septations. despite repeating the abdominal ultrasound in multiple planes, it remained unclear whether the structure represented a distended fluid-filled loop of colon or a unique cystic lesion. subse- quent computerized axial tomography (fig. ) revealed a multiseptated cystic structure in the pancreatic tail mea- suring . · · cm with peripheral hyperdensities com- patible with extrapancreatic calcifications. several of the cystic components demonstrated thickened walls with mild enhancement. the pancreatic parenchyma and pancreatic duct appeared normal. no other pancreatic le- sions were identified. multiple mildly dilated fluid-filled loops of large and small bowel with air-fluid levels com- patible with gastroenteritis were also noted, which were felt to be the likely etiology of his symptoms. the patient’s symptoms resolved shortly following his emergency room visit, with normalization of his stools and resolution of his abdominal pain. after care- ful review of his images, his pancreatic lesion was felt to represent a cystic pancreatic mass and less likely a pseudocyst or a solid pseudopapillary tumor with cystic components. he was referred for an endoscopic ultra- sound (eus) to further characterize his lesion. an eus (fig. ) performed in december noted a . · . cm thick-walled pancreatic tail lesion with a hypoechoic center and several adjacent anechoic lesions, the largest of which was . · . cm. the pan- creas otherwise appeared normal. fine needle aspira- tion of the largest anechoic lesion was performed using a g expect� bsci needle. one milliliter of pink tinged nonviscous fluid was aspirated. cyst fluid analysis revealed carcinoembryonic antigen . ng/ml and amylase u/l. aspirate cytology was nondiag- nostic with rare small groups of mildly atypical epithe- lial cells, benign acinar cells, ductal cells, and fragments of fibrous tissue and debris. redpath pathfindertg� integrated diagnosis was also indeterminate, due to lack of polymerase chain reaction amplifiability from low dna quantity and poor dna quality. the patient felt generally well and

tomography in july demonstrated a persis- tent pancreatic cystic lesion measuring . · . · . cm, with prior imaging not available for comparison at that time. although a definitive diagnosis had not been estab- lished, due to his recurrent pain and persistent lesion, the patient underwent laparoscopic excision in july . the patient tolerated the procedure well. the lesion was easily dissected from the pancreas. macroscopically, it was noted to have four cystic components, ranging in size from . · . · . to . · . · cm. each cyst con- tained a white smooth wall filled with white cloudy watery fluid. microscopically, the cysts were lined by a single layer of cuboidal to columnar epithelium with focal acini, with one cyst demonstrating internal concretions (fig. ). no cytological atypia or mitoses were present. these features were consistent with a multilocular acinar cell cystadenoma. discussion we have described a case of a young adolescent male with a multilocular acinar cell cystadenoma who underwent suc- cessful cyst excision. to our knowledge, he is the second youngest patient to have been reported with this lesion. in addition, although nearly all previously reported cases of aca resulted in extensive pancreatic resections, including pancreaticoduodenectomy, lateral pancreatec- tomy, and total pancreatectomy, we have described a case with successful cyst excision without pancreas resec- tion. postoperatively, we have recommended every other year magnetic resonance imaging/magnetic resonance cholangiopancreatography surveillance for this patient. whether or not this is warranted or beneficial, especially given this patient’s young age at diagnosis, is unclear. it has been proposed that aca originate from nonneo- plastic acinar dilatation that expand into and incorporate ducts and ductules, eventually forming large cystic lesions as secretions accumulate. ductal-to-acinar metaplasia has also been a theoretical explanation. more recently, however, pancreatic acinar cell cystadenoma has been described as an adenoma. although it has been sug- gested that this lesion is a precursor to acinar cell cysta- denocarcinoma, the true malignant potential of this lesion remains unclear. to our knowledge, no case re- port or case series has reported evidence of malignant transformation of aca with up to . -year follow-up, regardless of whether or not the lesion was completely resected. , although aca lack atypia and mitotic activity that seems to favor a nonneoplastic lesion, the discovery of multiple chromosomal gains on compara- tive genomic hybridization that contain a few cancer- associated genes and genomic instability suggests the le- sion is preneoplastic. in addition, a case of aca with low-grade dysplasia was recently reported. we know from previous studies that aca are likely to grow over time. in a case series of patients, of whom underwent sequential imaging, all four cysts showed in- terval enlargement over time with a mean increase of . cm for more than . years. no postoperative recur- rences have been reported. until the course of aca is better established, however, we believe these lesions should be aggressively monitored, with strong consider- ation for surgical resection to reduce the theoretical risk of malignant transformation. given the rarity of these cysts, future studies to support this will likely be limited. author disclosure statement no competing financial interests exist. references . zamboni g, terris b, scarpa a, et al. acinar cell cystadenoma of the pan- creas: a new entity? am j surg

i, castello de la plana, spain. the voltage-dependent anion channel (vdac) governs the exchange of ions and metabolites between the mitochondria and the rest of the cell. in its open state vdac exhibits high conductance and selectivity for anions that facilitates the passage of adp, atp, and other metabolites. at increased voltages (> mv) vdac switches to lower conducting states, termed as ‘‘closed’’ states. closed states are cation-selective and impermeable for atp. the voltage-induced transition from the open to closed states is referred to as voltage-gating. although it is well established that vdac voltage-gating in- volves large structural rearrangements, the precise molecular mechanism of this process is still under debate. we investigated vdac voltage-gating by sys- tematically titrating vdac charge residues and by using thermodynamic and kinetic approaches to study opening and closing of the channel. all the models proposed so far agree that n-terminal region plays a key role in vdac voltage- gating. according to the original idea, the n-terminal region is a part of a mo- bile voltage sensor domain, which slides in and out of the channel lumen in re- sponse to the applied voltage. the alternative models consider independent movement of the n-terminal region upon gating. in order to test the role of vdac n-terminal region in voltage-gating, we engineered a double cys mu- tant of murine vdac that cross-links the a-helix to the b-strand of the pore wall. the cross-linked vdac reconstituted into planar lipid membranes exhibited typical voltage gating, which suggests that the n-terminal a-helix is located inside the pore of vdac in the open state and remains associated with the pore wall during voltage gating. our findings support a model where b-bar- rel is not rigid but undergoes a conformational change that leads to a partial constriction upon transition to the closed states. -pos board b novel mechanism of mitochondrial respiration control through competition between hexokinase- and tubulin for vdac binding kely l. sheldon , coert j. zuurbier , sergey m. bezrukov , tatiana k. rostovtseva . the natl. institutes of health, bethesda, md, usa, university of amsterdam, amsterdam, netherlands. the voltage dependent anion channel (vdac) is involved in regulation of me- tabolite flux across the mitochondrial outer membrane (mom). hexokinse ii (hk ) is known to bind the mom where it phosphorylates glucose into glucose- -phosphate (g p). high expression of hxk is a common phenotype of many cancers, where its concentration can be times of that in noncan- cerous cells, and is implicated in the warburg effect. it is believed that vdac serves as a hxk binding site in the mom. the amino acid n-ter- minal sequence of hxk is responsible for mitochondrial binding and, when conjugated to tat (tat-hk ), binds to mitochondria with higher affinity than native hxk , causing hxk detachment. we have previously found that dimeric tubulin reversibly binds and partially blocks vdac inhibiting me- tabolite flux across the mom. now we show that this binding can be attenuated by tat-hxk peptide as well as by full length hxk . we have found that tat-hxk and recombinant full length hxk inhibit tubulin blockage of vdac reconstituted into planar lipid bilayers without altering characteristic channel properties such as single channel conductance and selectivity. binding of hxk to vdac is verified by the generation of high-frequency excess cur- rent noise without channel closure. hxk bound to vdac prevents subse- quent tubulin binding, but only when added before tubulin, and inhibits tubulin-induced vdac blockage in a dose dependent manner. moreover, g p, which is known to cause hxk detachment from the mom, fully re- verses the inhibition of tubulin-vdac binding. this suggests that hxk de- tachment from vdac (and hence the mom) is caused by a hxk conformational change upon g p binding. thus we propose a novel mecha- nism of mitochondrial respiration control in cancer cells through the competi- tion between hxk and tubulin for vdac binding. -pos board b reprogramming of mitochondrial ca d handling in micu -deficient hela cells tünde golenár , györgy csordás , erin l. seifert , cynthia moffat , fabiana perocchi , yasemin sancak , david weaver , vamsi k. mootha , györgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, harvard medical school and massachusetts general hospital, boston, ma, usa. recent studies have revealed mcu as the pore forming domain and micu as a critical ca þ-sensitive regulator of the mitochondrial ca þ uniporter. how- ever, the exact role of micu in ca þ transport remains to be addressed. our previous studies showed that prolonged down-regulation of micu in hela cells (shmicu ) promotes mitochondrial ca þ uptake at low [ca þ ], which unexpectedly, fails to effectively increase matrix [ca þ ]. to determine the source of discrepancy between the mitochondrial ca þ uptake and the ma- trix [ca þ] phenotypes, first we simultaneously monitored ruthenium red- sensitive clearance of added ca þ from the cytoplasm and the corresponding matrix [ca þ] response in permeabilized shmicu cells. under conditions of similar cytoplasmic ca þ clearance, shmicu cells showed a smaller matrix [ca þ ] increase than the control, indicating enhanced buffering of ca þ in the matrix. enhanced ca þ binding in the matrix likely reflects alkalinization and enhanced phosphate transport. to test if upregulation of ca þ buffering is di- rectly linked to micu depletion, we also assessed mitochondrial ca þ han- dling after hr silencing of micu (simicu ). in simicu cells both mitochondrial ca þ uptake and the matrix [ca þ ] rise were effectively stimu- lated at low ca þ levels. thus, upregulation of matrix ca þ buffering seems to be a component of an adaptive response to sensitization of mitochondrial ca þ uptake in shmicu . the adaptive response is likely to be important to attenuate some micu -depletion induced cellular impairments that we found to manifest as attenuated mitochondrial atp production and cell proliferation. -pos board b micu -dependent threshold and cooperativity of mitochondrial ca d uptake in the liver györgy csordás , erin l. seifert , tünde golenár , cynthia moffat , sergio de la fuente perez , david weaver , roman bogorad , victor koteliansky , vamsi k. mootha , györgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, koch institute for integrative cancer research, mit, cambridge, ma, usa, harvard medical school and massachusetts general hospital, boston, ma, usa. recent studies have revealed mcu as the pore forming domain and micu as a critical ca þ-sensitive regulator of the mitochondrial ca þ uniporter. how- ever, the mechanism of the complex ca þ dependence of the uniporter activity remains elusive. our previous studies showed that prolonged down-regulation of micu in hela cells causes lower threshold and decreased cooperativity of mitochondrial ca þ uptake. to study the functional significance of the effects of micu we used hepatocytes harvested from the liver of mice exposed to in vivo silencing ( weeks). silencing of micu or mcu resulted in > % decrease in their respective mrna levels. silencing of micu caused a left- ward-shifted dose response and decreased cooperativity of mitochondrial ca þ uptake in both permeabilized and intact hepatocytes. by contrast, silenc- ing of mcu resulted in slower ca þ uptake in the entire range of ca þ concen- trations without change in threshold. mitochondrial respiration and cellular atp content were unaffected in media containing both glycolytic and mito- chondrial fuels in either micu or mcu-deficient hepatocytes. however, si- lencing of micu caused an augmented loss of atp when the cells were confined to oxidative metabolism and an enhanced sensitivity to mitochondrial ca þ overload and permeabilization. during stimulation with vasopressin, a ca þ mobilizing hormone, both micu and mcu-deficient cells displayed an attenuated mitochondrial matrix [ca þ ] increase and stimulation of respira- tion. collectively, these results show that keeping the gate of mcu closed by micu at low [ca þ] is required to maintain healthy mitochondria, and micu -mediated control of mcu (cooperativity?) is required to support the propagation of short-lasting calcium spikes and oscillations to the mitochondria and the ensuing physiological stimulation of oxidative metabolism. -pos board b targeting mcl- and bak as a therapeutic tool to selectively induce apoptosis in hepaptocellualr carcinoma nima niknejad, soumya sinha roy, eric knudsen, györgy hajnóczky. thomas jefferson university, philadelphia, pa, usa. in this study we seek to identify novel drug targets to induce apoptosis in he- patocellular carcinoma (hcc) cells thus providing opportunities to develop novel treatments to improve the prognosis of liver cancer patients. several ap- optotic pathways are mediated through cleavage of bid (a bh domain-only, pro-apoptotic protein) to produce truncated bid (tbid). tbid induces apoptosis through induction of outer mitochondrial membrane (omm) permeabilization by activation of pro-apoptotic bak that resides in the omm or cytoplasmic bax. due to its localization, bak can mediate the early phase of the response to tbid. we have recently demonstrated that omm targeting of bak and the sensitivity to tbid-induced omm permeabilization is dependent on the expression of a wednesday, february , voltage-dependent anion channel isoform (vdac ). here, we show that hcc induced by carcinogenic compounds, aflatoxin or den is highly sensi- tized to tbid-induced omm permeabilization and cyto c release when com- pared to normal liver. expression levels of vdac and bak were also higher in hcc than in control liver. the role of the vdac -bak pathway in the differential tbid sensitivity was validated by overexpression of vdac in primary hepatocytes. in hcc cells, elevation of bak was also associated with an increased level of mcl- , an inhibitor of bak. furthermore, both constitutive and drug-induced genetic deletion of mcl- in mouse embryonic fibroblasts caused sensitization to tbid-induced omm permeabilization in the absence of a change in bcl-xl or bax . based on these results, we are evaluating the possibility of selective killing of hcc cells by the combination of a bak activator and an mcl- inhibitor. -pos board b which domain of vdac is necessary for bak insertion to the outer mitochondrial membrane and tbid - induced cytochrome c release? shamim naghdi , peter varnai , soumya sinha roy , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadlephia, pa, usa, semmelweis university, budapest, hungary. vdac proteins represent a main component of the outer mitochondrial membrane (omm). the vdac family is composed of isoforms with more than percent similarity. although their primary role was known to be in ion and metabolite transport between mitochondria and cytosol, it has been dis- covered that vdacs are also involved in apoptotic pathways. we have recently found that specifically the vdac isoform is needed for tbid-induced cyto- chrome c release, due to its role in supporting bak insertion to the omm (roy et al. . embo rep. : - ). to determine the domain(s) of vdac which supports bak insertion, vdac and vdac amino acid composition compared and the unique attributes of vdac sequencewereconsideredformutationalanalysis.totestfunctionalsig- nificance of the changes in vdac or vdac , vdac -/- mef cells that are resistant to tbid, were transfected with the mutants and insertion of bak to the omm and cytochrome c release were monitored in permeabilized cells by immunoblotting. previously, we showed that the vdac -specific n terminal tail and cysteins are dispensable for tbid-induced omm permeabilization. to approach the remaining differences four chimeras were prepared: vdac ( - )vdac ( - ), vdac ( - )vdac ( - )vdac ( - ), vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ). these studies revealed that tbid dependent omm permeabilization is only sup- ported by vdac ( - )vdac ( - ) and vdac ( - )vdac ( - ), indicating that the first two third of vdac is required and sufficient for bak targeting to the omm and tbid induced cytochrome c release. -pos board b outer mitochondrial membrane protein distribution and function depend on mitochondrial fusion david weaver , xingguo liu , veronica eisner , peter varnai , laszlo hunyady , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary. cells and tissues deficient in mitochondrial fusion have been shown to have defects linked to the exchange of inner membrane (imm) and matrix compo- nents, particularly mitochondrial dna. outer membrane (omm) constituents originate in the cytoplasm, thus the role of intermitochondrial transfer of omm components by fusion remained unexplored. here we show that fibro- blasts lacking the gtpases responsible for omm fusion, mfn / , have a more heterogeneous distribution of omm proteins than wild-type cells, and in partic- ular that heterogeneity of pro-apoptotic bak leads to dysregulation of bid- dependent apoptotic signaling. homogeneous distribution of bak is partially rescued by introduction of mfn into mfn / -/- cells. furthermore, fusions be- tween mitochondria lacking and containing bak result in hybrids sensitive to bid. proteins with different modes of omm association display varying degrees of heterogeneity in mfn / /- cells and different kinetics of transfer during fusion in fusion-competent cells. efficient coupling of omm to imm fusion depends on the presence of both mfn isoforms and is antagonized by the mitochondrial fission protein, drp . thus, omm function depends on mitochondrial fusion and is a locus of dysfunction in conditions of fusion deficiency. -pos board b mitochondrial fusion dynamics in skeletal muscle of healthy and diseased rat veronica eisner , guy lenaers , gyorgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, inserm u- , institut des neurosciences de montpellier, montpellier, france. mitochondria are highly mobile and dynamic organelles in many cell types. however, in the muscle, mitochondria are crammed into the narrow space among the myofilaments. until now, it remained unclear if mitochondrial fusion occurs in and supports the contractile activity of skeletal muscle (sm). here we applied mitochondria matrix-targeted dsred and photoactiv- able gfp to study mitochondrial fusion in rat fdb sm fibers. in vivo electro- porated fibers were imaged by confocal microscopy. when we tagged the mitochondria in ~ % of cell area with twophoton photoactivation of gfp, rapid spreading of fluorescence showed subsets of interconnected mitochondria, mostly in longitudinal direction. matrix fusion occurred with a rate of . and . events/min in adult fibers and skeletal myotubes, respectively. expres- sion of autosomal dominant optical atrophy-causing mutants of the fusion protein opa or ethanol exposure caused suppression of fusion, which is fol- lowed by mitochondrial dysfunction and late onset myopathies. when chal- lenged by repetitive tetanic stimulation, ethanol exposed cells displayed intracellular ca þ dysregulation, appearing as a fatigue pattern. ethanol also induced a decrease in mfn protein levels, without significantly altering mfn , opa or deltapsi. depletion of mfn alone was sufficient to suppress mi- tochondrial fusion in fdb fibers. fusion inhibition was apparent before any cell dysfunction, suggesting that suppression of fusion is not secondary to other problems in the cells. to directly test the role of mfn in ca þ regulation, ryr -transfected control and mfn ko mefs were stimulated with caffeine. mfn ko cells showed oscillatory ca þ transients that decayed faster than that in the control. thus, fusion dynamically connects skeletal muscle mito- chondria and serves as a target mechanism of both mutations and environmen- tal cues to cause impaired excitation-contraction coupling. -pos board b bcl- proapoptotic proteins distribution in u- mg glioma cells before and after hypericin photodynamic action katarina stroffekova, lucia balogová, mária maslaňáková, lenka dzurová, pavol mi�skovský mi�skovský. safarik university, kosice, slovakia. apoptosis is a key process in the development and maintenance of tissue homeostasis. this process of controlled cell death is tightly regulated by a balance between cell survival and damage signals. we focused our attention towards the intrinsic mitochondrial apoptotic pathway, where bcl- family of proteins plays the major role. we were particularly interested in two pro- apoptotic players bak and bax. here we investigated their role in apoptosis triggered by photodynamic action. we show the localization of bax and bak in u- mg human glioma cells incubated with photosensitizer hypericin (hyp) before and after photodynamic action. apoptotic stimulus by hyp photodynamic action caused bax translocation into mitochondria. however our results suggest that under these condi- tions there are two populations of mito- chondria: one which contains bax and bak simultaneously, and is almost exclu- sively localized near the plasma mem- brane; the other which contains bax only and is distributed throughout the cell. the different protein content and spatial distri- bution of these two populations suggest that they can play different roles in re- sponse to apoptotic stimuli. -pos board b stimulation of bax mitochondrial localization by bcl-xl thibaud renault , oscar teijido , gisele

mitochondria through protein-protein interactions between the bcl- family proteins. an imbalance of this interaction network due to the up-regulation of the proto-oncogenes bcl- and/or bcl-xl lead to a resistance to apoptosis and is associated with tumor formation. bcl-xl overexpression act at the level of the mitochondrial outer membrane (mom) by inhibiting bax-mediated apoptosis; more particularly mac formation and cytochrome c release. how- ever, the molecular mechanisms through which bcl-xl affect earlier steps of bax-mediated apoptosis are not fully understood. surprisingly, we found that mitochondrial bax redistribution and change of conformation were not inhibited but rather spontaneously increased in response of bcl-xl overexpres- sion. in order to further investigate the

during reperfusion lea k. seidlmayer, vanessa v. juettner, lothar a. blatter, elena n. dedkova. rush university medical center, chicago, il, usa. impairment of mitochondrial function is a central event of ischemia- reperfusion (i/r) injury leading to tissue damage and cell death. we studied the relationship between mitochondrial ca þ overload, reactive oxygen species (ros) generation, opening of the mitochondrial permeability transition pore (mptp) and cell death in rabbit ventricular myocytes exposed to simulated i/r. changes in mitochondrial ca þ ([ca þ]m) were measured with x-rhod- , ros generation with mito-sox red, mptp opening as mitochondrial calcein red release, and cell death as lactate dehydrogenase release. i/r was induced by exposing cells to glucose-free tyrode solution containing mm -deoxyglu- cose and mm nacn, ph . , followed by superfusion with standard tyrode solution. no cell death was observed after min of ischemia despite a signif- icant increase in [ca þ]m, ros and mptp opening, however cell death in- creased significantly after min of reperfusion. the ca þ uniporter blocker ru partially prevented [ca þ ]m increase and completely abolished ros generation and cell death when applied during i/r, however application of ru only during reperfusion did not protect from cell death. scavenging ros with superoxide dismutase mimetic mntbap or antioxidant trolox pre- vented reperfusion-induced cell death. blocking mptp during ischemia by cyclosporine a or depletion of mitochondrial inorganic polyphosphate did not provide protection against cell death during reperfusion, but instead led to increased mitochondrial ros accumulation. however, inhibiting mptp opening during reperfusion with cyclosporine a attenuated cell death. we con- clude that mptp-dependent cell death during reperfusion is mediated by ca þ- dependent ros generation during ischemia. moreover, our data suggest that mptp opening during ischemia could serve as ros escape pathway from mitochondria and thereby attenuate mitochondrial ros accumulation and ros-mediated cell damage during subsequent reperfusion. -plat dynamic measurement of ca d -induced changes in organelle-specific redox microdomains david m. booth , balázs enyedi , miklós geiszt , péter várnai , györgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary. multiple interactions between ca þ -signalling and reactive oxygen species (ros) production are thought to exist and be of both physiological and patho- physiological relevance. however, until recently, the study of ros in the con- text of ca þ-signalling has been hampered by ros probes limited in both specificity and targeting. to measure ros in discrete subcellular domains, we compared the genetically-encoded ratiometric h o sensor hyper with the redox de-sensitized derivative sypher to control for non-specific changes. these probes, targeted to the er lumen, er membrane (cytosolic face), cyto- sol, mitochondrial matrix and outer membrane (omm) and the ip -receptor, are positioned to assess redox changes at a local level. in resting conditions, the er lumen showed > -fold increased hyper ratio compared to the outside of the er membrane, bulk cytosol and mitochondrial matrix and omm. in the er lumen, ip -linked ca þ -mobilization induced a prounounced, downward shift in hyper ratio, whereas little or no change was detected in other compart- ments. in permeabilized cells, mitochondrial ca þ-overload was accompanied by substantial increase in h o detected in the matrix and at the omm. these data demonstrate that redox environments within individual cellular compart- ments constitute a complex and dynamic interrelationship with the concentra- tion of free ca þ . the er lumen is highly oxidized and exhibits profound decreases in h o concommitant with ca þ -release. interestingly, these changes are not transmitted to the outer leaflet of the er membrane or to other compartments. mitochondria resist redox changes under moderate stimulation, however, during mitochondrial ca þ-overload and collapsed membrane poten- tial, strong h o generation is detectible in the matrix and at the mitochondrial surface. the ros generated and detected at locations immediately apposed to ca þ -transport proteins, such as the ip -receptor, may modify their function at a local level and contribute to the feed-forward cycle of ca þ -dysregulation and subsequent cell death. -plat er-mitochondrial ultrastructure in the liver of normal and ethnaol-fed rats

alcohol consumption causes severe pathology in liver, associated with altered metabolism and reduced atp production. liver mitochondria isolated from alcohol-fed animals show decreased capacity for electron transport and atp synthesis, impaired calcium handling, and increased ros. in parallel, the endoplasmic reticulum (er) also shows increased ros and a stress re- sponse. the close correlation between defects in mitochondria and er is matched by recent evidence of the functional integration of cellular responses (including calcium signaling) involving these organelles. to evaluate the ultra- structural basis of alcohol-induced changes, we performed transmission elec- tron microscopy and electron tomography studies of rat liver. hepatocytes showed a large number of mostly round mitochondrial cross sections, which oc- cupied ~ % of the cytoplasmic area. the cell cytoplasm in chronic ethanol- fed ( months) condition exhibited reduced particle density, indicative of cell swelling, and contained large lipid vesicles. the mitochondria were generally intact but showed narrower intermembrane spacings within cristae and at the organelle periphery, consistent with low-scale matrix swelling. in both control and ethanol-fed conditions, mitochondria were typically surrounded by exten- sive er, with cisternae sometimes sandwiched between neighboring mitochon- dria. in one case, er was prominent at a site of mitochondrial fusion/fission. as previously reported, regions of close er-mitochondrial association ( - nm) contained numerous ‘‘tethers’’ between outer mitochondrial membranes (omm) and adjacent er. while individual tethers were discernible, dense granular material (including ribosomes) within omm-er interfaces interfered with accurate quantitation of tethers. however, membrane spacings could be readily measured. it was found that the mitochondrial surface in close associ- ation with er was significantly reduced in the chronic ethanol-fed condition as compared to control ( . % vs. %). this might be expected to cause reduced calcium signaling between er and mitochondria in liver after chronic alcohol ingestion. -plat mitochondrial nm -h

activity as a nucleoside diphosphate kinase (ndpk), using mitochondrial atp to regenerate nucleoside triphosphates. nm -h is further known to strongly bind in vitro to anionic phospholipids, mainly cardi- olipin, and in vivo to inner mitochondrial membranes. we show here that such protein/lipid complexes inhibit ndpk activity but are necessary for nm -h to function in selective intermembrane lipid transfer. nm -h -deficient hela cells expressing either wild-type nm -h or a membrane-binding deficient mutant were analyzed by membrane fractionation and lc-esi-ms. data revealed that wild-type nm -h increased cardiolipin content in the outer mitochondrial membrane as compared to mutant enzyme. this correlated with higher susceptibility of wild-type enzyme expressing cells to rotenone-induced apoptosis as seen by increased annexin v binding, elevated caspase / activity and stimulated release of cytochrome c into the cytosol. molecular modeling of nm -h binding with cardiolipin reveals potential intermembrane transfer mechanisms. we propose that nm -h acts as a lipid-dependent mitochondrial switch with dual function, allowing either for phosphotransfer or for cardiolipin transfer, with a role in apoptotic signaling. calcium-induced ros generation during ischemia triggers mptp-dependent cell death during reperfusion dynamic measurement of ca +-induced

the editorletter to the editorletter to the editor letter to the editor to the editor—as part of the ispor education steering committee, the ispor fellowship task force was formed in the spring of . the task force’s mission is to define the fundamentals of a core curriculum for pharmacoeconomic and out- comes research (pe/or) fellowships, as well as to foster knowledge of these programs among students of various scientific and professional backgrounds. as a result, in the task force began a research study to provide insight into the characteristics and components of the pe/or fellowship programs. the results of this study have recently been described in two articles published in the american journal of pharmaceutical education [ , ]. a brief description of the main research findings is presented. pe/or fellowship programs have been in exist- ence in the united states for more than a decade. with the increasing number of programs, however, it has become difficult to quantify the exact number of programs offered, and little is known about how these programs are structured [ ]. the objectives of the study conducted by the ispor fellowship task force were: ) to describe the organizational structures and educational compo- nents of pe/or fellowship programs within the united states and ) to determine the extent to which these programs adhere to the ameri- can college of clinical pharmacy (accp) pe fel- lowships guidelines. from november through december , the task force conducted a cross-sectional, web- based survey via the ispor web site. the survey population consisted of fellows as well as precep- tors involved in a pe/or fellowship, who were identified by collecting information through differ- ent sources including the accp and ispor direc- tories for these programs. the task force developed a set of three questionnaires, which were adminis- tered, respectively, to current fellows enrolled in a fellowship, to fellows who had finished a fellow- ship, and to preceptors currently involved in a fel- lowship. of the individuals completing the survey, current fellows, former fellows, and preceptors met the inclusion criteria. according to fellows and preceptors’ responses, the results of the study revealed that pe/or fellow- ships have numerous similarities in terms of their general characteristics, as well as their organiza- tional and educational aspects [ , ]. therefore, a common profile for these programs can be described as shown in table . with a program years in length, sponsored by the pharmaceutical industry, and conducted predominantly in academic and pharmaceutical industry sites, pe/or fellow- ships reportedly provide trainees with adequate resources to carry out scientific research [ ]. in addition, programs offer applicants exposure to a variety of types of research design and analysis to enhance their knowledge about pe/or. according to preceptors’ opinions, current pe/ or fellowships appear to adhere to the accp guidelines [ ]. in particular, preceptors reported that programs show significant compli- ance with the main aspects of the guidelines, which define both the structure and the process of fellowships. few preceptors, however, indi- cated that their programs currently offer trainees hands-on research activities at the level suggested by these guidelines. in conclusion, as an initiative of the ipsor fellowship task force, this is the first study to describe the current state of pe/or fellowship programs in the united states. the results of these investigations provide substantial insight to institutions and organizations wishing to develop new or refine existing pe/or fellowship pro- grams.—vittorio maio, pharmd, ms, office of health policy, clinical outcomes, thomas jeffer-

). sequence analysis of the mammalian vdac isoforms shows a unique n terminal end in vdac , which is likely to be exposed to the cyto- plasm. to test the functional significance of this n terminus, the first amino acids were removed from vdac or were added to vdac . vdac -/- mef cells that are resistant to tbid, were rescued with these constructs and cyto- chrome c release was monitored in permeabilized cells by single cell imaging and immunoblotting. these studies revealed that cytochrome c release upon tbid application is effectively supported by both full length vdac and the vdac n-terminal deletion mutant. furthermore, vdac extended by the n terminus of vdac failed to restore cytochrome c release in vdac -/- mefs. thus the n terminus of vdac seems to be dispensible for tbid- induced omm permeabilization. currently, we are designing different muta- tions which target some addititional unique sequences in vdac to find the specific domain that is essential for tbid induced cytochrome c release. -plat patch-clamp analysis of mitochondrial ca d uniporter in different tissues francesca fieni, yuriy kirichok. ucsf, san francisco, ca, usa. the mitochondrial ca þ uptake has been recognized as a central player in cel- lular pathophysiology for decades. pathways of ca þ transport across the inner mitochondrial membrane (imm) were investigated indirectly with biochemical techniques and most recently by applying the patch clamp technique to mito- plasts isolated from mammalian systems. patch-clamp recording of the imm have proved to provide an unambiguous picture of mitochondrial ca þ uptake under strictly controlled conditions. in this study, we evaluated and compared the biophysical properties of mito- chondrial ca þ uptake in different mouse tissues. freshly isolated mitoplasts from mouse heart, skeletal muscle, liver, kidney, spleen and brown adipose tis- sue were patch clamped in the whole-mitoplast configuration. voltage step and ramp protocols covering the whole range of physiological potentials were ap- plied to elicit the inwardly rectifying ca þcurrent sensitive to rur known as mcu. the distribution of mcu current densities between tissues was as fol- lows: spleen > brown adipose tissue z skeletal muscle > kidney > liver >> heart. interestingly, mcu current density in heart was about times smaller than in skeletal muscle. our results support the view of a differential tissue activity of mcu, which can be explained by either a different distribution of mcu channel and/or by a different expression of its regulatory subunits confer- ing various modes of physiological regulation. further on, in order to investigate the putative direct contribution of uncou- pling protein isoform and (ucp / ) to the uniporter, we investigated mcu properties in wild type (wt) mouse tissues where these two proteins have been found to have a major role and compared its properties in the corre- spondent tissues of ucp and ucp ko mice. we found no significant differ- ences in calcium currents of any of the wt tissues studied compared to their ucp / ko counterparts. -plat sr-mitochondrial ultrastructure in the heart of normal and ethanol-fed rats gyorgy csordas , david mankus , tanvir shaikh , xing meng , jan hoek , carmen mannella , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, wadsworth center, albany, ny, usa. chronic alcoholism causes various forms of stress in the heart, and this is often accompanied by mitochondrial dysfunction. a putative source of mitochondrial dysfunction is sr-mitochondrial stress and the ensuing mitochondrial ca þ overload. to test this possibility, first we isolated mitochondria from chronic ethanol-fed ( months) and paired control rats, and documented ethanol- dependent sensitization to ca þ and ros-induced permeabilization. to evalu- ate the ultrastructural basis of the mitochondrial impairments, we performed transmission electron microscopy (tem) and electron tomography studies of left ventricular muscle. the overall ultrastructure of the myocytes became less organized in the ethanol-fed condition. also, a considerable fraction of the mitochondria lost the highly ordered structure of the cristae and showed an increase in the cross-sectional area. however, the size of the sr- mitochondrial associations and the gap-width at the interface was unchanged. evaluation of the sr-mitochondrial tethers by electron tomography indicates that they occur in clusters and display heterogeneity in length, as previously re- ported for er-mitochondrial tethers in normal rat liver (csordas et al, , j cell biol, : ). overall tether length distribution appears to be unaltered by alcohol ingestion. analyses of effects of alcohol ingestion on tether membrane-surface density and structural classes (linear, v, y and more com- plex shapes) is in progress, as is d analysis of ser and mitochondrial inner- and outer-membrane topologies.

importance of honesty (scanes, ). this editorial discusses the is- sues of transparency. in my opinion, transparency is one of the requirements for engendering trust, and trust is critical to so much of what we do. a culture of transparency is essential for research. the results section of a paper is arguably the most im- portant section. we expect that the results presented fairly summarize the data obtained. it is clearly wrong to selectively present data to be included. this is fal- sification of results and this is scientific misconduct. the corollary is that we should not bury data that does not fit with our well-established position or working hypothesis. alter the results or there is statistical sig- nificance. again, this is falsification of results and sci- entific misconduct. i encourage authors to place their raw data into the journal’s data repository (as a data supplement) linked electronically to the paper. a culture of transparency is also important for a journal. there needs to be clarity of expectations. for instance, what statistics are appropriate to report? an area where transparency is not used is with review of manuscripts. i firmly believe in the peer-review process: reviewers need keep confidential the manuscripts they review, and papers are frequently reviewed “blind”; that is, not identifying the authors or the institution where the research was conducted. i say “frequently” because an experienced reviewer can often discern the labora- tory where the work was done. a culture of transparency is critically important for teaching. students need to understand the expectations of the instructor. what metrics will be used? what materials will be covered and at what level? how will the textbook be used? most importantly, when will ex- aminations and tests occur? i would argue for a culture of transparency in a uni- versity, a company, a government laboratory, and in so- ciety as a whole. thomas jefferson stated that, “when- ever the people are well-informed, they can be trusted with their own government.” i would suggest that this be paraphrased to “when people are well-informed, they trust their own government.” references scanes , c.

professions studies; director, college of arts & sciences medical/dental scholars program; faculty, university of delaware historical foundation origin the office of the provost created a taskforce in the spring of to examine the status of “premedical education at the university of delaware” existing at that time. membership on the taskforce was highly diverse with representatives from thomas jefferson university, christiana care hospital services, the college of arts & sciences, the college of health sciences, the office of admissions, and premedical/health profession students. dr. david barlow from the college of health sciences was designated chair. the taskforce was charged to review and evaluate current premedical studies practices, with the goal of making recommendations for changes perceived essential for enhancing the success of all students in gaining admission into medical schools and other health profession programs. the first major recommendation endorsed unanimously by the taskforce was to create a “center for premedical and health profession studies.” the focus of this center would be to help students across all colleges who wanted to pursue careers in the health professions. the provost’s taskforce viewed the center as the best approach for advising pre-health profession students in a comprehensive manner. locations a three-year agreement was created in the summer of to locate and host the new center for premedical and health profession studies (cphps) within the facilities of the career services center. reporting to the office of the provost, the center was formally announced with a university-wide opening ceremony in january of . the center’s goal was to benefit students in all colleges, and the success of the center would depend on university-wide support. the cross-college initiative is reflective of a new emerging approach to healthcare which is inter- professional and across disciplines. initial funding for the center came in part from a unidel grant received in . the name of the center was shortened to the center for health profession studies (chps) in . following an almost two-year temporary location in hullihen hall, the center was formally relocated and re-dedicated at its permanent location in e pearson hall in october of (see figure ). figure . pearson hall initial staffing initial staffing included the assignment of a center director (david barlow) and an administrative assistant (laura pawlowski). the demand for staffing increased dramatically and, starting in , expanded to include a program manager, two partial workload faculty health professions advisors (hpa), a miscellaneous wage hpa/hpec assistant, a graduate assistant hpa, and a number of undergraduate assistants/peer mentors. the additional staffing served to address a rapid increase in the demand for advisement services, the growing popularity of numerous co-curricular programs, and the increased sponsored activities that the center provides students. mission statement and goals the center for health profession studies supports and encourages students from all majors who are pursuing careers in the health professions. the center remains focused on student outcomes – helping students achieve success in careers that they have chosen: medicine, dentistry, optometry, podiatry, physician assistant, advanced practice registered nurse, pharmacy, physical/occupational therapy and other health profession programs. the center provides advisement and referral services to a growing community of pre-health profession students in all colleges in their academic and extracurricular preparation to improve success of acceptance into healthcare profession programs. over students utilized the resources and services of the center in alone. three main goals of the center are to: • help students make informed decisions about their choice of a future healthcare profession. • promote academic excellence by providing accurate and up-to-date guidelines for completing pre-health profession curricular requirements, for thoroughly understanding all admission requirements, and for using all available resources of the center. • support active student engagement within the healthcare community, primarily through clinical work, voluntary service, and translational research. services/program activities of the center in addition to group meetings, special programs, field trips, and sponsored monthly guest lecturers, students may seek individual assistance from the center. students can schedule an appointment via email, online, or phone to meet with one of the health professions advisors. additionally, center administrative staff members are available for walk-in students to meet briefly, one-on-one, to discuss their academic goals or concerns. no appointments are necessary and students are seen on a first-come, first-served basis. walk-in hours are provided during the fall and spring semesters. a few phone appointments are set aside each week. standardized test preparation resources kaplan/nextstep/uworld/examkrackers and other standardized test preparation programs are frequently supported often with financial incentives/discounts to aid pre-health profession students in their preparation for mcat/dat/gre examinations. pre-health profession’s living learning community since the center has created and sponsored a highly successful first-year pre-health professions living learning community for freshmen students interested in pre-health professions. students accepted into the program have the opportunity to live in close proximity with over other freshmen, mentored by two upperclassman peer mentors and one graduate assistant, all who have similar career interests and are taking similar courses. the students have access to extra support from faculty and staff of the center to pursue career and graduate school interests. in addition, they have access to professionals knowledgeable about standardized tests (e.g., mcat), graduate school applications, academic, and co-curricular requirements. programs and events in the residence hall include exciting speakers from the healthcare industry, extracurricular enrichment, health-related volunteer experiences, and social events. since the initiation of this living learning community, the program has produced a remarkable % retention rate over the past five years. medical internships abroad programs students have the opportunity to participate in exciting health profession medical internship opportunities abroad sponsored by the center during special sessions. since , over students have performed medical internships traveling to seven different countries including spain, portugal, italy, greece, hungary, china, and turkey in partnership with the university institute of global studies and a program called atlantis. in all the programs, students shadow doctors, interact with health profession students from other cultures, and gain an understanding of international healthcare systems. in june of , students participated in st. george’s university “summer leadership academy” in the west indies experiencing introductions to their medical, veterinary, and public health professional programs of study on the island of granada in the west indies. all of these study abroad experiences hosted and guided by ud faculty help students distinguish themselves as outstanding applicants for medical school and other health-related professional schools. premedical post-baccalaureate certificate program this unique program, limited to post-baccalaureate students, is designed for those qualified individuals who have previously completed a bachelor's degree in a non-science related field but who now want to fulfill the requirements for admission to medical, dental, or other health profession schools. accepted students work closely with the center to develop a structured individualized program of study that addresses the academic and co-curricular requirements to be considered for admission to medical, dental, or other health profession schools. since , over % of these post baccalaureate students completing this program achieving a certificate of academic excellence have successfully matriculated into medical/physician assistant programs of study. designed to support “career changers”, this program is affiliated with the philadelphia college of osteopathic medicine which is a part of a cohort agreement with the ud post baccalaureate program. collaborations the center has established affiliations/agreements with area hospitals and healthcare organizations to provide ud students with unique learning experiences. some of these include the delaware institute for medical education and research (dimer) and the delaware health science alliance (dhsa). in addition, the center has agreements with christiana care health system and st. francis hospital of wilmington. these latter affiliations support approximately premedical studies students each year performing over hours each of shadowing medical preceptors in a variety of different healthcare settings. in the past this also included shadowing opportunities for students in the delaware division of forensic science. through the medical scholars program, the center has formal affiliations with the sidney kimmel medical college at thomas jefferson university, the philadelphia college of osteopathic medicine, and the rowan university school of osteopathic medicine. the center sponsors frequent field trips to these institutions as well as to other institutions such as the pennsylvania state university hershey college of medicine, cooper medical school of rowan university, and the geisinger commonwealth school of medicine. in addition, students in the past have visited the virtual education simulation training center at christiana care health system. medical scholars program (msp) established in , the medical scholars program is a unique early admissions premedical + academic program in the center sponsored by the college of arts and sciences at the university of delaware and by the sidney kimmel medical college of thomas jefferson university. as a dual major, eight-year academic program, in / the ud msp expanded to affiliate with the philadelphia college of osteopathic medicine and the rowan school of osteopathic medicine. it is designed for students who are certain that they want to become physicians and who desire a program that blends the scientific and cultural aspects of the medical humanities. the msp is accomplished by providing highly qualified students with a balanced education in liberal arts, science, and professional studies. the program includes the traditional courses in the life/physical sciences as well as a specialization in areas related to medicine dealing with bioethics, administration and public policy, translational research, or nutrition and health. small group discussions, problem-based instruction, and discipline specific practicum experiences in clinical/ institutional settings, all experienced with strong mentoring, are special aspects of this program. to become a part of this early conditional acceptance programs, students in the second semester of their freshman year attend an orientation meeting to declare an interest in the program. students are required to attend monthly medical scholar program (msp) meetings, accumulate volunteer/shadowing hours, obtain letters of recommendation, and achieve academic excellence. during the spring semester of the sophomore year, students from this group complete an application to the program, and as qualified rising juniors, are recommended by the university of delaware for interviews at one of the prestigious medical school cohorts. following a successful interview, students are granted provisional acceptance to medical school. students then declare a second major, bachelor of arts in liberal studies, completing the core science medical school requirements, combined with studies in the arts, humanities, and social sciences. seniors in the msp must continue to demonstrate a high level of academic performance and achieve a minimum score on the mcat prior to medical school matriculation. since , a total of students have obtained baccalaureate degrees in the medical scholars program resulting in a medical school matriculation rate of % in post-graduate year one (pgy ) (see figure ). in pgy the success rate rises to a remarkable % over this same period. dimer eligible in-state students accounted for slightly more than % of these former ud msp graduates. in the past years a total of medical practica/internships were performed by these same students involving at minimum , hours of shadowing healthcare professionals regionally and internationally. note that the major percentage of these shadowing hours were supported by christianacare and other local area medical facilities such as st. francis hospital in wilmington. the msp is operated through the center for health profession studies under the direction of david a. barlow, phd, since . figure . recent ud msp graduates now in medical schools center future goals the center for health profession studies strives to expand services to students and alumni not only to the university, but also to our neighboring state institutions who are considering careers in the various health professions. available to students across all majors and colleges, the center will continue to enable a growing population of students who are interested in the highly competitive health profession careers to make conscious and thoughtful decisions about their future paths. increased guidance and resources are provided along the “pre-health profession” pathways, from curricular planning, to securing clinical and research opportunities, to preparation for required standardized tests, to participation in health-related internships/in- service activities, and finally to the successful completion of the application process for medical, dental, veterinary and other health profession graduate schools. for more information about the center, please visit: center for health profession studies, university of delaware e pearson hall academy street newark, delaware

constraints and binding energetics of a potassium channel inactivation gate gaurav venkataraman, deepa srikumar, miguel holmgren. nih, bethesda, md, usa. voltage-activated potassium (kv) channels open an intracellular gate in re- sponse to changes in transmembrane voltage, allowing k þ to permeate at rates near diffusion. in some kv channels, permeation can be interrupted by the n-terminus of the protein acting as a blocking particle, binding at the intracel- lular cavity of the channel and physically obstructing the permeation pathway. despite being tetramers, kv channels require only one bound n-terminus to inactivate. in nature, inactivation is targeted by rna editing, which converts an isoleucine of the intracellular cavity into a valine. the functional conse- quence is a large increase in unbinding kinetics. how does each ‘‘wall’’ of the cavity contribute to the increase in unbinding kinetics of a single bound n-terminus? to address this question we made con- catenated shaker heterotetramers consisting of only one free n-terminus and a single isoleucine to valine mutation at position (i v), mimicking the rna editing site in humans and rodents. surprisingly, the rate of unbinding was the same for individual i v mutations in each wall; each corresponded to a decrease in binding energy of about . rt. in fact, the binding energy de- creased linearly as a function of the number of i v mutated subunits. these results suggest that despite being tethered to a particular subunit, the single in- activation particle has sufficient freedom to interact with position of each subunit with roughly equal probability. where does this freedom come from? it is expected that the inactivation gates enter the cavity through lateral ‘windows’, similarly to k þ . can our single tethered inactivation gate enter through each of the four windows of the protein? we will address this question by making individual cysteine mutations at each window and testing the inac- tivation gate’s binding kinetics after chemical modification. -pos board b gating interactions between the cytoplasmic t domain and pore of a kv channel brian urbani, manuel covarrubias. jefferson medical college of thomas jefferson university, philadelphia, pa, usa. whereas the gating roles of the voltage-sensing and pore domains of kv channels have been extensively investigated, much less is known about the mechanisms governing the regulation of gating by the cytoplasmic t domain. previous work from this lab strongly suggests that the kv . t domain un- dergoes conformational changes directly linked to gating (j. gen. physiol., : - , ); however, the structural basis of the communication between the activation gate and the t domain has remained elusive. to tackle this problem, we applied cysteine scanning mutagenesis, voltage- clamp electrophysiology, double mutant cycle analysis (dmca) and oxidizing reagents to probe specific interactions between the cytoplasmic t domain l helix, the s -s linker and s tail. the energetic impact of the mutations on activation gating is apparently small. by comparison, the energetic impact of the mutations on inactivation gating was significantly greater. dmca of k c(l )þa c(s ) revealed a significant interaction energy ( kcal/ mol), which suggests an interaction between k in the l helix and a in s . supporting this possibility, the currents induced by k c(l )þ a c(s ) are inhibited (~ % of control) by an oxidizing agent (tbuho ), whereas the single mutants are not; and the effect is reversed by the reducing agent dtt. these results indicate the formation of a disulfide bond between the interacting side chains, which is consistent with physical interaction between k (l ) and a (s ). overall, we conclude that regulation of inactivation gating by the t domain involves a physical interaction between the t l helix and the distal segment of s . supported by nih grant r ns (mc). -pos board b is the activation gate closed in kv channel closed-state inactivation? jeffrey d. fineberg, manuel covarrubias. thomas jefferson university, philadelphia, pa, usa. kv .x channel complexes including auxiliary subunits such as dpp -s and kchip undergo preferential closed-state inactivation (csi; baehring and covarrubias, , j physiol, . : - ; fineberg et al., , j gen physiol, in press). however, the molecular basis of csi in kv .x channels remains poorly understood. a key unanswered question of this problem is whether the channel’s activation is actually closed, as csi implies. we have previously proposed that csi results when the activated channel fails to open or simply prefers to close. this hypothesis specifically suggests that the intra- cellular activation gate may adopt a stable closed conformation, even under depolarized conditions that would initially favor the activated ‘‘up’’ state of the voltage sensors. to test this hypothesis, we are exploiting the trapping paradigm previously investigated by holmgren et al. to test the state of the intracellular activation gate ( , j gen physiol, : - ). essentially, if the activation gate closes behind a quaternary ammonium (qa) blocker inside the pore, the blocker cannot exit the pore; effectively, it is trapped. we are expressing the ternary kv . /i c channels (this mutation favors trap- ping) including dpp -s and kchip in xenopus oocytes. then, in the inside- out patch-clamp configuration, we are using a computer-controlled perfusion system to deliver the qa derivative decyltrimethylammonium bromide (c ) to the bath and probe the ability of the channel’s activation gate to trap c in the closed, open and inactivated states. preliminary results show that the trapping paradigm may yield an answer to the central question of this study. if the activation gate is indeed closed during csi, c trapping will only occur when the drug is applied to the conducting channel, but no trapping of c will be observed in the closed and inactivated states.

city university of ny, new york, ny, usa. quantum calculations on the open gate and the immediately surrounding re- gion of the kv . voltage gated potassium channel show that water adopts two conformations there, one when the ion is present, and another with no ion present. an energy minimum at the gate with no ion allows an ion to enter from the solution; from the gate it repels an ion in the channel pore cavity into the selectivity filter (essentially the ‘‘knock-on’’ mechanism). the pore cavity minimum can then be occupied by the ion moving from the gate minimum, leaving it available for anion from bulk, so the cycle continues. the arrange- ment of water, and the ion hydration, defines the gate energy minimum, and this in turn depends on the highly conserved prolines, especially p ( a pdb numbering), in the pvpv sequence in the gate. absent an energy minimum at the gate an ion entering from solution would be repelled back into solution by the ion in the cavity. furthermore, the ion remains hydrated by water molecules, at least more than in bulk, as it passes through the gate, based on optimizations with the ion at three different positions: ) at the gate position nearest p ) å above ) å below, this position. the open gate maintains very nearly the same protein atom positions throughout. additional calculations will be required to determine the exact interaction en- ergy with an ion in the cavity, and the amount of water that is present in the cavity. optimizations of the system configuration were done at hf/ - gsp level, with atoms ( with the ion). energy was determined using both b lyp/ - g* and bvp / - g*, but the system was too large for free en- ergy determination. -pos board b water structure at the potassium channel gate: the importance of the prolines in the pvpv sequence, as shown by computational mutations, and the role of a histidine in gating alisher m. kariev, michael e. green. city college of the city university of ny, new york, ny, usa. conservation of the pvpv sequence at the potassium channel gate has not been well understood. quantum computations (optimization at hf/ - gsp level) of the gate of the kv . channel that are presented here show that the proline-proline distances (ring atoms) are preserved as the ion moves through the gate. this calculation is supplemented by mutating one of the prolines to valine (p v, a pdb numbering for all residues in this abstract) in the computation, producing a pvvv sequence. water structure changed dramati- cally, as the protein backbone moved inward nearly å, effectively closing the channel; the proline ring n-n distance between diagonally opposite pro- lines dropped from . å (distance from optimization: x-ray distance = . å) to . å, too small to allow passage of a hydrated k þ . this suggests that the prolines play a key structural role, modulating both protein and water structure. furthermore, protonation of h may close the channel. protonation of this histidine shows it moving toward the gate by about å, which should close the gate electrostatically, while deprotonation opens the gate. protonation was calculated with two added protons, the other being accepted by e of the t intracellular moiety. when deprotonated, the histidine does not move as much as å from the x-ray position in the optimization, and is linked to e ; this accounts for the known importance of the t segment in gating. e , also of t , could accept a third proton. there is a salt bridge structure including these residues similar to the one occupying a key position in the pro- ton pathway in the hv channel. access constraints and binding energetics of a potassium channel inactivation gate gating interactions between the cytoplasmic t domain and pore of a kv channel is

chlorophyte algal ancestor to an apicomplexan ancestor ( ). waller et al. ( ) oppose this interpretation based on a phylogeny implying close affilia- tion of apicomplexan cox a and cox b genes with ciliate cox homologues; a -bp in- sertion that separates the corresponding do- mains in ciliate mitochondrial cox genes; and low hydrophobicity values for ciliate mitochondrial coxii and apicomplexan coxiia and coxiib subunits. they suggest that mitochondrial cox genes were split and transferred to the nuclei of the apicomplexan and chlorophyte ancestors during indepen- dent events. we find their phylogenetic argument uncon- vincing because, as they admit, statistical sup- port for the position of the ciliate sequences is lacking. affiliation of ciliates and apicomplex- ans previously noted in mitochondrial sequence phylogenies should also be interpreted with caution because both lineages are rapidly evolv- ing and may be artifactually grouped due to long-branch attraction ( ). furthermore, the ad- dition of ciliate cox sequences to our previous phylogenetic analysis ( ), does not show a re- lationship between ciliates and apicomplexans (fig. , a and b). nevertheless, we are pleased that in agreement with our findings in ( ), waller et al. ( ) confirm the common branch for apicomplexan and chlorophyte coxiia and coxiib sequences—an otherwise unex- pected affiliation. the presence of an insertion in the mito- chondrial cox genes of ciliates does not nec- essarily imply kinship with apicomplexan frag- mented cox a and cox b genes. the cox gene is susceptible to insertions between regions that encode the hydrophobic and hydrophilic do- mains of coxii. insertions of variable lengths have been described in cox genes of unrelated organisms ( ), including brown marine algae (nc_ , nc_ ), microflagellates (nc_ ), and bacteria (nc_ ). localization of insertions in cox is most likely constrained by the difficulty of inserting in the gene without disrupting the structure of the coxii protein ( ). ciliates also exhibit an in- sertion in cox and a fragmented mitochondrial nad ( ). these rearrangements most likely occurred after the divergence of ciliates from apicomplexans and dinoflagellates ( ), since no sequence remnants of insertions are present in cox in apicomplexans ( ) or dinoflagellates ( ). the cox and cox insertions were most likely absent in the alveolate ancestor and were acquired by ciliates independently. therefore, the proposed vertical inheritance of cox a and cox b genes in apicomplexans is not directly supported by the presence of insertions in ciliate cox . the hydrophobicity analysis presented by waller et al. ( ) provides no evidence for a common origin of ciliate coxii and apicom- plexan coxiia and coxiib sequences. we agree that hydrophobicity is one of the rate- limiting steps in functional gene transfer from the mitochondrion to the nucleus ( , – ). it is therefore not surprising that apicomplexan coxiia and coxiib subunits exhibit di- minished hydrophobicity. nevertheless, the low mean hydrophobicity values of ciliate mitochondrial coxii sequences merely indi- cate that, from the hydrophobicity point of view, the corresponding genes are ready to migrate—not that they migrated in the distant past. ciliate mitochondrial dna (mtdna) contains more than the standard set of genes encoded by mtdna in other eukaryotes ( ) and therefore does not seem to show an in- creased rate of gene migration. the hydro- fig. . phylogenetic analysis of coxii.

( ) would imply that this domain conservation is due to convergent evolution, which we consider unlikely. the correspond- ing borders of the ciliate coxii insertions and the apicomplexan coxiib extensions reveal no similarities (fig. c). we originally described rare characteris- tics that are shared solely between apicom- plexans and certain chlorophyte algae ( ), namely, the presence of nucleus-encoded split cox a and cox b genes and a conserved domain present in a region of coxiib that is not derived from orthodox coxii. functional fragmentation of a mitochondrial gene followed by functional integration in the nucleus is an extremely rare event, unlikely to happen several times. the current evidence suggests that this phenomenon was confined to the ancestor of chlorophyte algae. our analyses support a close relationship between apicomplexan and chlorophyte cox a and cox b sequenc- es specific to the mitochondrion, whereas analysis of apicoplast genome organization has suggested a red algal origin of the organelle ( ). clearly, there is still con- flicting evidence for green versus red algal ancestry in the apicomplexans ( ). what- ever the outcome of this debate, the pres- ence of nucleus-encoded, fragmented cox a and cox b genes of green origin in apicom- plexans must be considered whenever the evolutionary story of these parasites is re- constructed. soledad funes instituto de fisiologı́a celular universidad nacional autónoma de méxico (unam) d.f., mexico edgar davidson department of biochemistry and molecular pharmacology thomas jefferson university philadelphia, pa , usa adrián reyes-prieto instituto de fisiologı́a celular, unam susana magallón instituto de biologı́a, unam pascal herion instituto de investigaciones biomédicas, unam michael p. king department of biochemistry and molecular pharmacology thomas jefferson university diego gonzález-halphen instituto de fisiologı́a celular, unam e-mail: dhalphen@ifc.unam.mx references and notes . s. funes et al., science , ( ). . r. f. waller, p. j. keeling, g. g. van dooren, g. i. mcfadden, science , ( ); www.sciencemag. org/cgi/content/full/ / / a. . g. burger et al., j. mol. biol. , ( ). . m. p. oudot-le secq et al., j. mol. evol. , ( ). . x. pérez-martı́nez et al., j. biol. chem. , ( ). . n. m. fast et al., j. eukaryot microbiol. , ( ). . j. e. feagin, int. j. parasitol. , ( ). . s. lin et al., j. mol. biol. , ( ). . x. pérez-martı́nez et al., j. biol. chem. , ( ). . s. funes et al., j. biol. chem. , ( ). . d. o. daley et al., proc. natl. acad. sci. u.s.a. , ( ). . b. stoebe, k. v. kowallik, trends genet. , ( ). . j. d. palmer, j. phycol. , ( ). . sequences were aligned using clustalx ( ), with subsequent manual refinements. the corresponding aligned nucleotide sequences were used in the anal- ysis. agrobacterium was specified as outgroup. the model that best fits the data (gtr�i� �) and its parameters (base frequency: . , . , . , . ; rate matrix: . , . , . , . , . , . ; proportion of invariable sites: . ; shape of gamma distribution: . ) were identified with modeltest ( ) and implemented in heuristic searches with tbr branch swapping, to obtain a ml tree (score of –ln l � . ). branch support was obtained from ml bootstrap replicates con- ducted under the same model and parameters as the ml search. analyses were performed using paup* . b for macintosh and unix ( ). . j. d. thompson et al., nucleic acids res. , ( ). . d. posada, k. a. crandall, bioinformatics , ( ). . d. l. swofford, paup* . : phylogenetic analysis us- ing parsimony (*and other methods) (sinauer asso- ciates, sunderland, ma, ). march ; accepted may t e c h n i c a l c o m m e n t july vol science www.sciencemag.org b o n a p ril , h ttp ://scie n ce .scie n ce m a g .o rg / d o w n lo a d e d fro m http://science.sciencemag.org/ response to comment on "a green algal apicoplast ancestor" gonzález-halphen soledad funes, edgar davidson, adrián reyes-prieto, susana magallón, pascal herion, michael p. king and diego doi: . /science.

in from wiltshire, england. john h. gibbon, jr, came from a long line of physicians, starting back in england, where his great-great-great grand- father had been a london physician. furthermore, previ- ous generations of gibbons were graduates of jefferson medical college. his father was a respected surgeon and co-chairman of the department of surgery at jefferson and had held many honorable positions, including the pres- idency of the american surgical association. although his father was his counselor in later years, his mother was more influential during his childhood. marjorie gibbon

lung cancer. he had an active laboratory and later became chief of general surgical services at massachu- setts general hospital. gibbon pursued a research fellow- ship position in dr churchill’s

hopkinson, dr churchill’s research assistant, and later dr gibbon’s wife, they published very efficiently in highly ranked journals such as the journal of clinical investigation and annals of surgery. - surgical career after an internship and clinical fellowships at the penn- sylvania hospital, dr gibbon became a faculty member as a surgeon in and later an assistant professor of sur- gery at the university of pennsylvania in . during world war ii, john gibbon, jr, volunteered for duty and was in the united states army from to . he served as major and lieutenant colonel on the surgical ser- vice for the nd evacuation hospital in the south pacific and later at mayo general hospital. in , he returned to his alma mater at the jefferson medical college, where he quickly ascended to the rank of full professor and in became the samuel d. gross professor of surgery and chairman of the department of surgery (figure ). he remained the head of the department and also a consultant surgeon at the pennsylvania hospital and veterans affairs hospital in philadelphia until his retirement in . curriculum vitae highlights although dr gibbon will always be known as the inven- tor of the cardiopulmonary bypass machine, he also made several other clinical contributions. he served on the edito- rial board of annals of surgery from to and was its chairman from to . he authored the textbook surgery of the chest, which is in its th edition and has set the standard as a reference in the field of cardiothoracic surgery. he was a member of the examination committee of the american board of surgery from to and served as its chairman from to . he was president of the american surgical association in , the aats for to , the society of vascular surgery for to , and the society of clinical surgery for to and was elected to the national academy of sciences in . among his numerous awards was the albert lasker clinical research award, which he received in , often referred to as the american nobel prize. , , accomplishments and contributions to the field of cardiothoracic surgery dr gibbon’s pursuit of advancing medicine was fueled by the well-described event in boston in october of , when a young woman, after an uneventful cholecystectomy, developed severe onset of chest discomfort and difficulties breathing, consistent with acute pulmonary embolism. she was moved to the operating room for constant close the journal of thoracic and cardiovascular surg observation. it was dr gibbon who was given the responsi- bility to assess her clinically and to document her pulse, res- piratory rate, and blood pressure every minutes starting at pm that day. he was ordered to inform dr churchill immediately when her vital signs would deteriorate so that an emergent embolectomy could be performed. dr gibbon reported that at am the next day, she had become apneic and was without a measurable blood pressure. dr churchill opened her chest, incised the pulmonary artery, removed the blood clot, and placed a side-biting clamp on the pulmonary artery, all within less than minutes. this patient, however, died, just as had most of the patients for whom dr friedrich trendelenburg had described this tech- nique in leipzig, germany, years earlier. for dr gibbon, it was this event that sparked the idea of a cardiopulmonary bypass machine, which would, years later, advance and revolutionize the entire field of cardiothoracic surgery. he described his thoughts as follows: during that long night, watching helplessly the pa- tient struggle for life as her blood became darker and her veins more distended, the idea naturally occurred to me that if it were possible to remove some of the blue blood from the patient’s swollen veins, put oxygen into that blood and allow carbon di- oxide to escape from it, and then inject continuously the now-red blood back into the patient’s arteries, we might have saved her life. we would have bypassed the obstructing embolus and performed part of the work of the patient’s heart and lungs outside the body. during the next decades, he continued his search for a heart–lung substitute, tireless and with utmost persever- ance. a fruitful collaboration with ibm corporation al- lowed him to develop and assemble a first model of a bypass machine, which was successfully used in canine ex- periments (figure ). an upgrade of his cardiopulmonary bypass machine allowed increased blood flow, allowing its use in humans (figure ). on may , , at the ery c march figure . dr gibbon and his wife mary

retirement at his family homestead in . theruvath and ikonomidis presidential perspectives pennsylvania hospital, the first successful use of dr gibbon’s heart–lung bypass machine was used on an -year-old woman, named cecilia bavolek. she had been diagnosed with an atrial septal defect, which had been undiagnosed until then, given the insufficient diag- nostic modalities of the previous era. although her parents had been told of some congenital heart disease, she had re- mained asymptomatic until she necessitated admission for severe fatigue and hemoptysis. dr gibbon operated with dr frank allbritten (who had invented the left ventricular apex vent) and of his residents using his heart–lung ma- chine. , by way of a clamshell incision, the defect was repaired primarily. the heart and lung functions were bridged with cannulation of the left subclavian artery and bicaval venous cannulation for minutes (figure ). ceci- lia bavolek had an uneventful recovery and was discharged home on postoperative day . , dr gibbon’s creative imagination, which was sparked in from the inability to help a dying patient, and his dedi- cation and perseverance in designing an efficient heart and lung substitute, led to the landmark operation in . although other national and international centers were ex- perimenting in an effort to assemble a heart–lung machine for clinical use in the late s and s, it was john the journal of thoracic and ca gibbon’s work as a physician and scientist in its ultimate definition that led to the first successful and safe conduct of open cardiac surgery. however, both of his subsequent patients whom he operated on a few months later using his heart–lung bypass machine died during the procedure. deeply disappointed by these failures to rescue these pa- tients, he chose to let additional clinical use of his machine be performed by others in the field. it is hardly surprising that he has been called the ‘‘father of extracorporeal circu- lation.’’ to honor dr gibbon at thomas jefferson univer- sity in philadelphia, his alma mater, one of the university hospital buildings has been renamed the ‘‘gibbon building.’’ summary of aats presidential address the presidential address of dr john h. gibbon, jr, ‘‘the road ahead for thoracic surgery,’’ presented at the st rdiovascular surgery c volume , number presidential perspectives theruvath and ikonomidis annual meeting of the aats, in philadelphia, april to , , was influenced by his extremely successful physi- cian and scientist career in an era when significant contribu- tions to cardiothoracic surgery had climaxed and revolutionized the field. he started by explaining how the field of thoracic surgery had slowly matured from an embryonic state in , when the aats was founded, to a youthful state in , and that it still had not attained maturity. he gave examples of the advancements in thoracic, cardiac, and pediatric cardiac surgery, including his own contribution of using his cardio- pulmonary bypass machine to perform safe open heart sur- gery. he delineated how these early advancements were only possible because of concomitant advancements and developments in other fields of medicine, such as the devel- opment of heparin, antibiotics, and a better understanding of cardiopulmonary physiology. dr gibbon stated that ‘‘much remains to be done,’’ specifically, increasing the safety of thoracic operations and understanding the physi- ology of cardiac ischemia and hypothermia-induced slow- ing of metabolic demand. the proposed transition of thoracic surgery from its youth in the s to manhood is what dr gibbon presented in the second part of his pres- idential address. he documented that in an era of funding abundance in which the department of health, education, and welfare had increased their spending fourfold from to and with well-equipped laboratories, the essential require- ment was well-trained physician-investigators. he then asked the question of whether enough young medical stu- dents and physicians have been properly educated in the methods of scientific education and have engaged in research. dr gibbon emphasized that a good researcher needs qualities such as honesty, integrity, passion, patience, persistence, and attention to detail and must be incorrupt- ible. he noted that many with these qualities might have no interest in research, but instead in teaching, and should not be institutionally forced into conducting experimental investigations. as such, he proposed that every academic institution should have positions designed solely for teach- ing and others solely to conduct research. he then stated that, during surgical education, at least year should be spent in a laboratory, where the young sur- geon in training will, at a minimum, become a critical reader of surgical published studies. after the formal surgical edu- cation, ‘‘the embryo surgeon’’ should pursue a second period of research, preferably at a different institution, to give young clinicians and investigators greater experience and the basics of conducting bench research. he empha- sized the significance of a good mentor, teacher, and inves- tigator. he finished his presidential address by providing the journal of thoracic and cardiovascular surg common errors in conducting research and the notion that fewer, but more concentrated, endeavors of the society toward properly motivated and qualified investigators will result in more significant contributions. personal life dr john h. gibbon, jr, met his wife mary hopkinson, or maly as she was known to most, at the age of . mary was the daughter of charles hopkinson, one of america’s great- est portraitists. they met as he started his research fellow- ship in february , in boston, where maly was working as dr edward d. churchill’s laboratory assistant at the massachusetts general hospital. they married on march , , and had children, mary, john, alice, and marjorie. gibbon retired from his chairmanship in and from then on indulged in poetry, painting, and sports, spending most of his time at the farm (figure ). a devastating heart attack took his life

plana, spain. the voltage-dependent anion channel (vdac) governs the exchange of ions and metabolites between the mitochondria and the rest of the cell. in its open state vdac exhibits high conductance and selectivity for anions that facilitates the passage of adp, atp, and other metabolites. at increased voltages (> mv) vdac switches to lower conducting states, termed as ‘‘closed’’ states. closed states are cation-selective and impermeable for atp. the voltage-induced transition from the open to closed states is referred to as voltage-gating. although it is well established that vdac voltage-gating in- volves large structural rearrangements, the precise molecular mechanism of this process is still under debate. we investigated vdac voltage-gating by sys- tematically titrating vdac charge residues and by using thermodynamic and kinetic approaches to study opening and closing of the channel. all the models proposed so far agree that n-terminal region plays a key role in vdac voltage- gating. according to the original idea, the n-terminal region is a part of a mo- bile voltage sensor domain, which slides in and out of the channel lumen in re- sponse to the applied voltage. the alternative models consider independent movement of the n-terminal region upon gating. in order to test the role of vdac n-terminal region in voltage-gating, we engineered a double cys mu- tant of murine vdac that cross-links the a-helix to the b-strand of the pore wall. the cross-linked vdac reconstituted into planar lipid membranes exhibited typical voltage gating, which suggests that the n-terminal a-helix is located inside the pore of vdac in the open state and remains associated with the pore wall during voltage gating. our findings support a model where b-bar- rel is not rigid but undergoes a conformational change that leads to a partial constriction upon transition to the closed states. -pos board b novel mechanism of mitochondrial respiration control through competition between hexokinase- and tubulin for vdac binding kely l. sheldon , coert j. zuurbier , sergey m. bezrukov , tatiana k. rostovtseva . the natl. institutes of health, bethesda, md, usa, university of amsterdam, amsterdam, netherlands. the voltage dependent anion channel (vdac) is involved in regulation of me- tabolite flux across the mitochondrial outer membrane (mom). hexokinse ii (hk ) is known to bind the mom where it phosphorylates glucose into glucose- -phosphate (g p). high expression of hxk is a common phenotype of many cancers, where its concentration can be times of that in noncan- cerous cells, and is implicated in the warburg effect. it is believed that vdac serves as a hxk binding site in the mom. the amino acid n-ter- minal sequence of hxk is responsible for mitochondrial binding and, when conjugated to tat (tat-hk ), binds to mitochondria with higher affinity than native hxk , causing hxk detachment. we have previously found that dimeric tubulin reversibly binds and partially blocks vdac inhibiting me- tabolite flux across the mom. now we show that this binding can be attenuated by tat-hxk peptide as well as by full length hxk . we have found that tat-hxk and recombinant full length hxk inhibit tubulin blockage of vdac reconstituted into planar lipid bilayers without altering characteristic channel properties such as single channel conductance and selectivity. binding of hxk to vdac is verified by the generation of high-frequency excess cur- rent noise without channel closure. hxk bound to vdac prevents subse- quent tubulin binding, but only when added before tubulin, and inhibits tubulin-induced vdac blockage in a dose dependent manner. moreover, g p, which is known to cause hxk detachment from the mom, fully re- verses the inhibition of tubulin-vdac binding. this suggests that hxk de- tachment from vdac (and hence the mom) is caused by a hxk conformational change upon g p binding. thus we propose a novel mecha- nism of mitochondrial respiration control in cancer cells through the competi- tion between hxk and tubulin for vdac binding. -pos board b reprogramming of mitochondrial ca d handling in micu -deficient hela cells tünde

usa, harvard medical school and massachusetts general hospital, boston, ma, usa. recent studies have revealed mcu as the pore forming domain and micu as a critical ca þ-sensitive regulator of the mitochondrial ca þ uniporter. how- ever, the exact role of micu in ca þ transport remains to be addressed. our previous studies showed that prolonged down-regulation of micu in hela cells (shmicu ) promotes mitochondrial ca þ uptake at low [ca þ ], which unexpectedly, fails to effectively increase matrix [ca þ ]. to determine the source of discrepancy between the mitochondrial ca þ uptake and the ma- trix [ca þ] phenotypes, first we simultaneously monitored ruthenium red- sensitive clearance of added ca þ from the cytoplasm and the corresponding matrix [ca þ] response in permeabilized shmicu cells. under conditions of similar cytoplasmic ca þ clearance, shmicu cells showed a smaller matrix [ca þ ] increase than the control, indicating enhanced buffering of ca þ in the matrix. enhanced ca þ binding in the matrix likely reflects alkalinization and enhanced phosphate transport. to test if upregulation of ca þ buffering is di- rectly linked to micu depletion, we also assessed mitochondrial ca þ han- dling after hr silencing of micu (simicu ). in simicu cells both mitochondrial ca þ uptake and the matrix [ca þ ] rise were effectively stimu- lated at low ca þ levels. thus, upregulation of matrix ca þ buffering seems to be a component of an adaptive response to sensitization of mitochondrial ca þ uptake in shmicu . the adaptive response is likely to be important to attenuate some micu -depletion induced cellular impairments that we found to manifest as attenuated mitochondrial atp production and cell proliferation. -pos board b micu -dependent threshold and cooperativity of mitochondrial ca d uptake in the liver györgy csordás , erin l. seifert , tünde golenár , cynthia moffat , sergio de la fuente perez , david weaver , roman bogorad , victor

and massachusetts general hospital, boston, ma, usa. recent studies have revealed mcu as the pore forming domain and micu as a critical ca þ-sensitive regulator of the mitochondrial ca þ uniporter. how- ever, the mechanism of the complex ca þ dependence of the uniporter activity remains elusive. our previous studies showed that prolonged down-regulation of micu in hela cells causes lower threshold and decreased cooperativity of mitochondrial ca þ uptake. to study the functional significance of the effects of micu we used hepatocytes harvested from the liver of mice exposed to in vivo silencing ( weeks). silencing of micu or mcu resulted in > % decrease in their respective mrna levels. silencing of micu caused a left- ward-shifted dose response and decreased cooperativity of mitochondrial ca þ uptake in both permeabilized and intact hepatocytes. by contrast, silenc- ing of mcu resulted in slower ca þ uptake in the entire range of ca þ concen- trations without change in threshold. mitochondrial respiration and cellular atp content were unaffected in media containing both glycolytic and mito- chondrial fuels in either micu or mcu-deficient hepatocytes. however, si- lencing of micu caused an augmented loss of atp when the cells were confined to oxidative metabolism and an enhanced sensitivity to mitochondrial ca þ overload and permeabilization. during stimulation with vasopressin, a ca þ mobilizing hormone, both micu and mcu-deficient cells displayed an attenuated mitochondrial matrix [ca þ ] increase and stimulation of respira- tion. collectively, these results show that keeping the gate of mcu closed by micu at low [ca þ] is required to maintain healthy mitochondria, and micu -mediated control of mcu (cooperativity?) is required to support the propagation of short-lasting calcium spikes and oscillations to the mitochondria and the ensuing physiological stimulation of oxidative metabolism. -pos board b targeting mcl- and bak as a therapeutic tool to selectively induce apoptosis in hepaptocellualr carcinoma nima niknejad, soumya sinha roy, eric knudsen, györgy hajnóczky. thomas jefferson university, philadelphia, pa, usa. in this study we seek to identify novel drug targets to induce apoptosis in he- patocellular carcinoma (hcc) cells thus providing opportunities to develop novel treatments to improve the prognosis of liver cancer patients. several ap- optotic pathways are mediated through cleavage of bid (a bh domain-only, pro-apoptotic protein) to produce truncated bid (tbid). tbid induces apoptosis through induction of outer mitochondrial membrane (omm) permeabilization by activation of pro-apoptotic bak that resides in the omm or cytoplasmic bax. due to its localization, bak can mediate the early phase of the response to tbid. we have recently demonstrated that omm targeting of bak and the sensitivity to tbid-induced omm permeabilization is dependent on the expression of a step forward in understanding the mechanism

patients with cancer face fear and anxiety related to their immunocompromised status, and early data suggest patients with cancer may be more susceptible to infection with sars-cov- . during this pandemic, a new vu- lnerability has arisen: how can patients receive life-sustaining treatment for cancer if they cannot get to the clinic or if the system is overwhelmed by patients with covid- ? how can patients stay in what may be the safest place for them—the home—while still receiving high-quality care? covid- provides an opportunity to recognize and improve on shortcomings in our cancer care delivery system: interacting with the health system puts already tenuous patients at risk for nosocomial infection, high-quality cancer care requires a high level of coordination that is challenging to achieve, and accessing care can be difficult or impossible for some individuals. moving components of cancer care into the home can facilitate high-touch care, minimize risk by reducing unnecessary exposures to the health system, and improve access to treatment. cancer care at home can augment or replace current models for clinic visits, chemotherapy, and acute care, deleveraging healthcare facilities as primary sites of care while ensuring safety for patients and providers, and improving patient-centeredness of care. al- though important during a pandemic, cancer care at home can also have a lasting impact when healthcare returns to “normal operations.” this commentary de- scribes home-based approaches for clinic visits, chemotherapy, and acute care; examines concerns stakeholders have raised about implementation of these approaches; and evaluates needs for the sustainability of cancer care at home after resolution of the pandemic. clinic visits the transition from in-person clinic visits to telemedicine-based virtual visits has been rapid and dramatic since the pandemic began. at jefferson health, jeffconnect, a telemedicine platform for virtual visits, has seen a -fold increase in use. this modality is appropriate for patients presenting for routine follow-up care or receiving oral chemotherapy, and can be readily adapted for patients receiving infusional treatments. similarly, we have found that supportive care services—including peer support groups, patient-facing educational courses, and palliative care appointments—readily lend themselves to the virtual format. hollander and sites recently outlined concerns regarding telemedicine: it’s too difficult, it’s too transactional, the physical examination is inadequate, it’s ineffective, and it’s not financially viable. as the uptake of telehealth during the pandemic has soared, clinicians and patients are now recognizing the many positive attributes of telehealth and its clinical effectiveness. although some of the mo- mentum telemedicine has experienced during covid- is due to temporary waivers that facilitate reimbursement, telemedicine has now been thrust into the mainstream, and the gains will inevitably pave the way for broader uptake in the future. chemotherapy patients are encouraged to shelter in place to minimize exposures to sars-cov- . for patients who

infusion suite, dozens of potentially immuno- compromised patients are collocated with a variety of healthcare providers who may be vectors for sars-cov- . for these patients, home-based chemotherapy, administered by a trained team, can be considered. chemotherapy at home remains uncommon in the united states, although models for its use exist globally. in these models, home-based chemotherapy has been safe, was preferred by patients, and could be administered at lower cost. the christie nhs foundation trust, the largest single-site cancer center in europe, recently described “christie at home,” a model of home-based anticancer therapy designed to reduce pressure on clinics and improve the patient experience. in this model, a trained nurse can deliver sub- cutaneous or intramuscular treatments or or intravenous treatments per day, with real-time documentation completed via g-enabled laptops. christie at home delivered , in-home treatments between and ; in , % of surveyed patients receiving care at home rated their care as excellent and indicated a preference for home-based care over other sites. in some cases, a physical care team may not be required for administration of therapy, which may further streamline treatment. for instance, at jefferson health, our specialty pharmacy can deliver certain injectable agents, such as leuprolide, to the patient’s home for self- administration. concerns surround home-based chemotherapy as well. these concerns include fear that it is not safe, that logistics are insurmountable, that it cannot be reimbursed, and that patients do not want it. successful models, both domestically and abroad, address these concerns. for example, penn medicine is now scaling a home-infusion demonstration program called “cancer care at home” (cc@h). this program provides different cancer drugs, which are typically provided in outpatient cancer settings, to patients with lymphoma or breast, prostate, lung, or head and neck cancer for home administration. patients discuss cc@h with their provider, who then prescribes home treatment in the electronic medical record. after insurance au- thorization and discussion of out-of-pocket costs by penn home infusion therapy, a courier delivers the treatment to the patient’s home (up to days in advance); the treatment is then administered in the home by a nurse. acute care in the era of covid- , minimizing unplanned and potentially preventable acute care use for patients with cancer is particularly important. these encounters, in- cluding emergency department (ed) visits, acute hospitalizations, and -day rehospitalizations, use limited resources and put patients, staff, and providers at increased risk for infection. however, the desire to prevent unnecessary acute care use by patients with cancer is not unique to the pandemic. many of these patients can be managed in the home setting via hospital-at- home models. although these programs are currently uncommon in the united states, they do exist and are increasing in number. for example, huntsman cancer institute currently operates huntsman at home (h@h), which provides acute care services for oncology patients who live within miles of the institute. this program was born out of a need to address full bed occupancy and after-hours ed visits. both of these problems are highly pertinent during a pandemic. h@h reports reduced hospitalizations, ed visits, and total costs among patients who participate in the program. concerns about safety, feasibility, patient-centeredness, and reimbursement exist for cancer hospital-at-home programs as well. despite these concerns, how- ever, hospital-at-home models exist and are expanding. reimbursement may be the biggest barrier, but payment models are developing. for example, in , the physician-focused payment model technical advisory committee recommended a bundled payment for home-based acute care (consisting of acute hospital-level care © jnccn—journal of the

alternative payment model. similar payment models exist in collaborations between health systems and private payers. cancer care at home is not a replacement for all care. much of cancer care should not transition to the home, and identifying which treatments, and for which patients, can be safely and effectively delivered at home is crucial. cancer care at home may not be appropriate for every eligible patient and will not be appropriate for every treatment. shared decision-making between clinicians, patients, and family members can help tailor care to the needs of the individual patient. ultimately, however, reserving facilities for those who truly need facility-level care will best serve all stakeholders. conclusions covid- has illuminated the need for reform of the cancer care delivery system. by moving components of care to the home, the current system could effectively engage patients and improve access to care while reducing unnecessary and risky exposure to the healthcare system. furthermore, increased time at home would align with a new proposed patient-determined quality indicator for cancer care: days at home in the last months of life. challenges remain if cancer care at home, which has the potential to be of critical importance during the pandemic, is to become a standard option for cancer care delivery after the pandemic. to be sustainable, virtual visits, chemotherapy, and acute care at home require reallocation of resources, development of infrastructure, and durable payment reform. covid- can be a catalyst for such change. we should leverage this momentum to transform care for our patients. disclosures: dr. bekelman has disclosed that he has received honoraria from optum and cvs health. dr. bekelman and dr. binder have disclosed that they

novel, calcium-independent, pkca-dependent signaling pathway, which results in mitochondrial depolarization. as a result, mitochondrial dys- function is likely to be a key contributor to the

university medical center, chicago, il, usa. impairment of mitochondrial function is a central event of ischemia- reperfusion (i/r) injury leading to tissue damage and cell death. we studied the relationship between mitochondrial ca þ overload, reactive oxygen species (ros) generation, opening of the mitochondrial permeability transition pore (mptp) and cell death in rabbit ventricular myocytes exposed to simulated i/r. changes in mitochondrial ca þ ([ca þ]m) were measured with x-rhod- , ros generation with mito-sox red, mptp opening as mitochondrial calcein red release, and cell death as lactate dehydrogenase release. i/r was induced by exposing cells to glucose-free tyrode solution containing mm -deoxyglu- cose and mm nacn, ph . , followed by superfusion with standard tyrode solution. no cell death was observed after min of ischemia despite a signif- icant increase in [ca þ]m, ros and mptp opening, however cell death in- creased significantly after min of reperfusion. the ca þ uniporter blocker ru partially prevented [ca þ ]m increase and completely abolished ros generation and cell death when applied during i/r, however application of ru only during reperfusion did not protect from cell death. scavenging ros with superoxide dismutase mimetic mntbap or antioxidant trolox pre- vented reperfusion-induced cell death. blocking mptp during ischemia by cyclosporine a or depletion of mitochondrial inorganic polyphosphate did not provide protection against cell death during reperfusion, but instead led to increased mitochondrial ros accumulation. however, inhibiting mptp opening during reperfusion with cyclosporine a attenuated cell death. we con- clude that mptp-dependent cell death during reperfusion is mediated by ca þ- dependent ros generation during ischemia. moreover, our data suggest that mptp opening during ischemia could serve as ros escape pathway from mitochondria and thereby attenuate mitochondrial ros accumulation and ros-mediated cell damage during subsequent reperfusion. -plat dynamic measurement of ca d -induced changes in organelle-specific redox microdomains david m. booth , balázs enyedi , miklós geiszt , péter várnai , györgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, semmelweis university, budapest, hungary. multiple interactions between ca þ -signalling and reactive oxygen species (ros) production are thought to exist and be of both physiological and patho- physiological relevance. however, until recently, the study of ros in the con- text of ca þ-signalling has been hampered by ros probes limited in both specificity and targeting. to measure ros in discrete subcellular domains, we compared the genetically-encoded ratiometric h o sensor hyper with the redox de-sensitized derivative sypher to control for non-specific changes. these probes, targeted to the er lumen, er membrane (cytosolic face), cyto- sol, mitochondrial matrix and outer membrane (omm) and the ip -receptor, are positioned to assess redox changes at a local level. in resting conditions, the er lumen showed > -fold increased hyper ratio compared to the outside of the er membrane, bulk cytosol and mitochondrial matrix and omm. in the er lumen, ip -linked ca þ -mobilization induced a prounounced, downward shift in hyper ratio, whereas little or no change was detected in other compart- ments. in permeabilized cells, mitochondrial ca þ-overload was accompanied by substantial increase in h o detected in the matrix and at the omm. these data demonstrate that redox environments within individual cellular compart- ments constitute a complex and dynamic interrelationship with the concentra- tion of free ca þ . the er lumen is highly oxidized and exhibits profound decreases in h o concommitant with ca þ -release. interestingly, these changes are not transmitted to the outer leaflet of the er membrane or to other compartments. mitochondria resist redox changes under moderate stimulation, however, during mitochondrial ca þ-overload and collapsed membrane poten- tial, strong h o generation is detectible in the matrix and at the mitochondrial surface. the ros generated and detected at locations immediately apposed to ca þ -transport proteins, such as the ip -receptor, may modify their function at a local level and contribute to the feed-forward cycle of ca þ -dysregulation and subsequent cell death. -plat er-mitochondrial ultrastructure in the liver of normal and ethnaol-fed rats gyorgy csordas , david mankus , antony anil noronha , jan hoek , carmen mannella , gyorgy hajnoczky . thomas jefferson university, philadelphia, pa, usa, wadsworth center, albany, ny, usa. chronic alcohol consumption causes severe pathology in liver, associated with altered metabolism and reduced atp production. liver mitochondria isolated from alcohol-fed animals show decreased capacity for electron transport and atp synthesis, impaired calcium handling, and increased ros. in parallel, the endoplasmic reticulum (er) also shows increased ros and a stress re- sponse. the close correlation between defects in mitochondria and er is matched by recent evidence of the functional integration of cellular responses (including calcium signaling) involving these organelles. to evaluate the ultra- structural basis of alcohol-induced changes, we performed transmission elec- tron microscopy and electron tomography studies of rat liver. hepatocytes showed a large number of mostly round mitochondrial cross sections, which oc- cupied ~ % of the cytoplasmic area. the cell cytoplasm in chronic ethanol- fed ( months) condition exhibited reduced particle density, indicative of cell swelling, and contained large lipid vesicles. the mitochondria were generally intact but showed narrower intermembrane spacings within cristae and at the organelle periphery, consistent with low-scale matrix swelling. in both control and ethanol-fed conditions, mitochondria were typically surrounded by exten- sive er, with cisternae sometimes sandwiched between neighboring mitochon- dria. in one case, er was prominent at a site of mitochondrial fusion/fission. as previously reported, regions of close er-mitochondrial association ( - nm) contained numerous ‘‘tethers’’ between outer mitochondrial membranes (omm) and adjacent er. while individual tethers were discernible, dense granular material (including ribosomes) within omm-er interfaces interfered with accurate quantitation of tethers. however, membrane spacings could be readily measured. it was found that the mitochondrial surface in close associ- ation with er was significantly reduced in the chronic ethanol-fed condition as compared to control ( . % vs. %). this might be expected to cause reduced calcium signaling between er and mitochondria in liver after chronic alcohol ingestion. -plat mitochondrial nm -h /ndpk-d is multifunctional: intermembrane cardiolipin transfer linked to apoptosis uwe schlattner ,

in the mitochondrial intermembrane space. the well established function of the en- zyme is phosphotransfer activity as a nucleoside diphosphate kinase (ndpk), using mitochondrial atp to regenerate nucleoside triphosphates. nm -h is further known to strongly bind in vitro to anionic phospholipids, mainly cardi- olipin, and in vivo to inner mitochondrial membranes. we show here that such protein/lipid complexes inhibit ndpk activity but are necessary for nm -h to function in selective intermembrane lipid transfer. nm -h -deficient hela cells expressing either wild-type nm -h or a membrane-binding deficient mutant were analyzed by membrane fractionation and lc-esi-ms. data revealed that wild-type nm -h increased cardiolipin content in the outer mitochondrial membrane as compared to mutant enzyme. this correlated with higher susceptibility of wild-type enzyme expressing cells to rotenone-induced apoptosis as seen by increased annexin v binding, elevated caspase / activity and stimulated release of cytochrome c into the cytosol. molecular modeling of nm -h binding with cardiolipin reveals potential intermembrane transfer mechanisms. we propose that nm -h acts as a lipid-dependent mitochondrial switch with dual function, allowing either for phosphotransfer or for cardiolipin transfer, with a role in apoptotic signaling. calcium-induced ros generation during

intelligence (ai) is now integrated into a variety of fields, including medicine. ai applications raise numerous ethical questions, particularly about quality of care and patient- clinician relationships. this article accompanies digital photo- paintings that address these ideas narratively and visually, with special emphasis on communication, compassion, and competence. three c’s excellence is widely regarded as an attribute of good health care quality, often defined in terms of communication, compassion, and competence. restricted time is an obstacle to acquiring and mastering these c’s if health care delivery systems focus too narrowly on volume and ignore patients’ and clinicians’ needs for compassion. ai power artificial intelligence (ai) is currently being adopted in many sectors, including health care. the power of ai technologies is evident in innovations in processing huge amounts of data, deep-learning algorithms, and expansion of machine learning capacity to learn in less time than it takes a human being. ai applications in health care include faster and often more accurate diagnosis through image recognition, pathology detection, and diagnostic assessment. quality care and patient-clinician relationships ethical questions have been raised about ai’s capacity to undermine or extinguish compassion and human connection in health care. if properly implemented in caregiving, however, ai could nurture excellence and motivate organizational cultures in which the c’s could be practiced and cultivated with rigor, diligence, and care. for example, while an ai application is executing tasks, clinicians might be able to spend time communicating with patients, expressing compassion, and delivering care with competence and satisfaction. , incorporating ai-based decision aids could also boost clinicians’ confidence in care management decisions. www.amajournalofethics.org representing the c’s visually the first image

clinical trials. similarly, trials with oncolytic viral therapies alone or in combination with immunological checkpoint inhibitors are categorized as oncolytic virus therapy trials. details of the targeted therapy and onco- lytic virus therapy trials are presented in table . targeted therapy clinical trials the current landscape of systemic therapy for cutane- ous melanoma is largely driven by immunotherapy. al- though effective in treating patients with cutaneous mel- anoma, response rates have been disappointing in uveal melanoma. different approaches, including targeted should also be explored in this field. four clinical trials are currently available utilizing targeted therapy. a phase trial of intermittent dosing of the mitogen-activated pro- tein kinase kinase (mek) enzyme inhibitor, selumetinib, in metastatic uveal melanoma patients who have not re- ceived prior mek inhibitor therapy (nct ), tar- gets the mitogen-activated protein kinase (mapk) path- way, regardless of tumor mutational status. oncogenic mutations in gnaq or gna are observed in more than % of primary uveal melanomas and activate signaling pathways primarily including the mapk pathway, which leads to cell proliferation and survival [ , ]. a prior randomized phase trial compared selumetinib to che- motherapy in metastatic uveal melanoma patients and found a modest benefit in pfs ( . vs. weeks) and in objective response rate ( vs. %) for those treated with selumetinib [ ]. however, treatment-related ad- verse events were observed in % of patients treated with selumetinib. with this trial, an intermittent dosing sched- ule may achieve a better toxicity profile and response rate if higher doses of selumetinib can be achieved. mutations in gnaq or gna also activate the pro- tein kinase c pathway, which also leads to cell prolifera- tion and survival and thus serves as another target for cancer-directed therapy. a current phase / basket trial is available to metastatic uveal melanoma patients and other solid tumors, which uses the drug ide in pa- tients harboring gnaq/ mutations or protein kinase c fusions (nct ). a recent phase study of ide in patients with metastatic uveal melanoma dem- onstrated encouraging clinical activity with / patients achieving a partial response and / with stable disease [ ]. the toxicity profile was tolerable, with % of pa- tients developing grade – adverse events, namely hypo- tension. while two dosing strategies were employed in this trial (once daily dosing and twice daily dosing), twice daily dosing was better tolerated and potentially exhibited longer duration of response. all patients (n = ) in the daily dosing regimen discontinued treatment due to pro- gressive disease, whereas patients in the twice-daily dos- ing regimen (n = ) remained on treatment for greater than months. of these patients, maintained a par- tial response and had stable disease [ ]. for this reason, the study design for ide includes a dose escalation phase for twice daily dosing to determine the recom- mended phase dose in patients with metastatic uveal melanoma, cutaneous melanoma, colorectal cancer, and other solid tumors. another target for clinical trials is double stranded dna damage repair genes. germline and somatic muta- tions in the double-stranded dna damage repair gene bap have been found in patients with uveal melanoma. parp / enzymes are responsible for repairing single- stranded dna breaks. inhibition by a parp inhibitor, along with a deficient dna damage repair gene, ultimate- ly leads to truncation of dna replication, transcription, and cell death, also known as synthetic lethality [ ]. sev- eral trials in other tumor types, specifically breast, ovari- an, and prostate cancers that target the brca / genes have successfully shown improved response rates and pfs with parp inhibitor therapy [ – ]. a current clin- ical trial is evaluating niraparib in bap and other dna damage response deficient neoplasms in metastatic uveal melanoma, mesothelioma, and renal cell carcinoma (nct ). similarly, another phase trial that is active, but not yet recruiting patients, is using the combi- nation of talazoparib (parp inhibitor) and nivolumab (anti-pd- immunotherapy) in metastatic uveal or cuta- neous melanoma patients that harbor a mutation in a dna damage repair gene (nct ). the dna damage repair genes included in this study are brca / and brcaness genes, which are specifically responsible for homologous recombination repair of dna. in cuta- neous melanoma, the combination of parp and pd- inhibition has shown to increase the immunogenicity of tumor cells by promoting t cell and natural killer cell in- filtration, and increasing tumor expression of pd-l in vitro and in vivo [ – ]. lastly, a phase / trial evaluates plx in advanced malignancies (nct ). plx is an inhibitor of bromodomain-containing protein (brd ), a bet family member, an epigenetic regulator that is known to exert key roles involved in chromatin remodeling and transcriptional regulation. brd is significantly upregu- lated in melanoma tissue; treatment with brd or bet inhibitors have shown to impair melanoma cell prolifera- clinical trials in metastatic uveal melanoma ocul oncol pathol ; : – doi: . / tion and tumor growth in vitro and in vivo [ ]. simi- larly, brd inhibition demonstrated cytotoxic activity in uveal melanoma cell lines and mouse xenograft models carrying gnaq/ mutations [ ]. oncolytic virus therapy clinical trials oncolytic viruses are also an alternate approach in treating metastatic uveal melanoma patients. oncolytic virus therapy has been utilized in cutaneous melanoma with the development of talimogene laher- parepvec (tvec), approved by the fda in october . tvec is currently being studied in combination to ex- pand its use and synergize with other interventions, in- cluding immune checkpoint inhibitor therapy. however, oncolytic virus therapy has not yet been introduced in the field of uveal melanoma. currently, two clinical trials are available for intratumoral injection of oncolytic virus therapy. one is a phase trial for anti-pd- naïve patients to receive gene therapy with intralesional injection of ad- enovirus-mediated expression of herpes simplex virus thymidine kinase (adv/hsv-tk) with valacyclovir and stereotactic body radiation therapy followed by nivolum- ab administration on day (nct ). this thera- peutic combination builds on the concept of “suicide gene therapy,” where a therapeutic gene-encoding en- zyme (adv/hsv-tk) is capable of transforming a non- toxic prodrug (valacyclovir) into a cell toxin that enhanc- es the cytotoxic effect within cancer cells and protects the healthy cells [ ]. another clinical trial using a modified virus is a phase study of vsv-ifnbetatyrp in pa- tients with metastatic uveal or cutaneous melanoma (nct ). the vesicular stomatitis virus (vsv) is altered to include two extra genes: human interferon beta (hifn-β), which may protect normal healthy cells from becoming infected with the virus, and tyrp , which is expressed mainly in melanocytes and melanoma tumor cells. tyrp can trigger a strong immune response to kill the melanoma tumor cells. vsv has been shown to have a rapid replication rate within the tumor and to be cyto- toxic in melanoma xenograft models. targeting tyrp antigen has been shown to increase cd t cells and il- in vitro and in vivo, resulting in increased immune cell infiltration into the tumor microenvironment [ – ]. liver-directed therapy clinical trials as up to % of patients with metastatic uveal mela- noma develop metastatic disease to the liver, recent stud- ies have suggested statistically significant improved pro- gression-free survival (pfs) and os with liver-directed therapy when compared to systemic therapy (median pfs . vs. . months; mos . vs. . months) [ ]. how- ever, when controlling for key patient characteristics, the os benefit for liver-directed therapies is no longer seen. five studies are currently available for metastatic uveal melanoma patients with significant liver disease burden and limited extrahepatic disease, which include: a phase / study of combination immunotherapy with ipilim- umab/nivolumab with sirspheres yttrium- internal hepatic radiation (nct ); combination ipilim- umab/nivolumab with immunoembolization (phase ) to liver metastases (nct ); phase isolated hepat- ic perfusion study where high concentration chemother- apy is perfused through the liver with minimal systemic exposure (nct ); a phase study of intralesion- al injection of pv- ( % rose bengal disodium), which has an expansion cohort of patients that can receive im- mune checkpoint inhibitor therapy (nct ); and a phase study of percutaneous hepatic perfusion with melphalan (nct ). this study (also known as the focus trial) delivers melphalan mg/kg using the delcath hepatic delivery system via percutaneous cath- eterization of the femoral artery to access the hepatic ar- tery to infuse the chemotherapeutic agent, and in the in- ferior caval vein to aspirate the chemosaturated blood re- turning through the hepatic veins, which is perfused through an extracorporeal filtration system, and then re- turned to systemic circulation. patients can receive up to six treatments at -week intervals. in another phase tri- al, percutaneous hepatic perfusion of melphalan was compared with best alternative care in patients with melanoma liver metastases. eighty-three patients in this study had uveal melanoma. hepatic pfs was significant- ly prolonged with melphalan infusion (median . vs. . months); however, no difference was observed in os (median . vs. . months) [ ]. cns-directed therapy clinical trial while uveal melanoma does not typically metastasize to the central nervous system, several case reports and case series have demonstrated leptomeningeal involve- ment [ , ]. data from metastatic cutaneous melanoma patients with leptomeningeal disease has shown a median os of only . months [ ]. limited treatment options are available for cutaneous and uveal melanoma patients with leptomeningeal disease with limited evidence of long-term clinical benefit from them [ ]. a current phase clinical trial available for uveal melanoma pa- tients with leptomeningeal disease involves the adminis- tration of intrathecal nivolumab with intravenous nivolumab beginning in cycle (nct ). sussman/funchain/singhocul oncol pathol ; : – doi: . / conclusions the current landscape of clinical trials available for treatment of metastatic uveal melanoma is comprised of active trials that encompass a range of modalities, in- cluding immunotherapy, targeted therapy, oncolytic vi- rus therapy, as well as liver-directed therapy, and cns- directed therapy. while informative, our review of avail- able clinical trials has limitations. while our search criteria were broad in order to encompass all clinical trials available for metastatic uveal melanoma, trials were large- ly limited to “recruiting” status. therefore, trials that opened or started recruiting after the search date of no- vember , , were not included in this review. as uve- al melanoma is a rare disease, we would expect a few trials may have opened after the search was performed. as no current standard of care therapy exists for metastatic uve- al melanoma, clinical trials are essential for developing new therapies and offering patients hope for improved outcomes. various novel therapeutic targets and immu- nomodulatory approaches are on the horizon and may yield incremental therapeutic benefit. selecting an appro- priate clinical trial can be overwhelming and should be made with a patient’s oncologist. oncologists and their clinical trial team can discuss with patients the details of a trial, eligibility criteria, and expected toxicity. addition- ally, oncologists can compare available clinical trials to standard of care therapy in the context of a patient’s co- morbidities, location, and burden of metastatic disease. conflict of interest statement tamara sussman has no conflicts of interest to

it refers to twins with fused head and thorax but separate pelves and limbs. if the single fused head has two faces each looking in opposite directions, the twins are referred to as cephalothoracopagus janiceps twins ( , ). the term janiceps has its origin in janus, the two‐faced roman god. when the two faces are asymmetrical and only one normal face can be seen alongside with a second incomplete face (single naris, cyclopic eyes, synotic ears, a proboscis, or two small eyes in a single palpebral fissure), it is called cephalothoracopagus article info abstract . /jogcr. . . background & objective: conjoined twins (cts) are rare complications of monozygotic twinning. cephalothoracopagus is the rarest subtype of cts and occurs once in every sets of conjoined twins or once in every three million births. here we present such a case and analyze the possible reasons for ultrasonographic misdiagnosis and recommend solutions to avoid it. case report: in this article, we have reported a case of cephalothoracopagus janiceps twining. the ultrasonographic diagnosis was missed at and weeks scans. increased thickness of nuchal translucency and absent nasal bone was observed alongside with suspected gastroschisis. the patient was referred for further evaluation at - weeks of pregnancy. unexpectedly, two alive fetuses were reported fused in the head, thorax, and abdomen. because of the poor prognosis, counseling was provided for parents and elective medical pregnancy termination was carried out. we have analyzed the possible reasons for ultrasonographic misdiagnosis. conclusion: without applying a standardized scanning of the entire uterus both in a longitudinal and transverse approach in early pregnancy, cephalothoracopagus twining may be misdiagnosed with a singleton pregnancy. a high level of concerns may raise for conjoined cephalothoracopagus twinning in case of finding a single fetal pole with an irregular body outline and a disproportionally large head in the presence of two separate fetal hearts in early pregnancy. two fused heads with two brains and two sets of lower and upper extremities do confirm the diagnosis. keywords: cephalothoracopagus janiceps, conjoined twins, ultrasonographic misdiagnosis received: / / ;

( ). the diagnosis was made by vaginal ultrasound examination at weeks' gestation from the findings of a single fetal pole with an irregular body outline, a disproportionally large head, and two separate cardiac pulsations and was confirmed after rescanning at weeks ( ). while early diagnosis of conjoined twins is feasible, it is not always easy in cephalothoracopagus twinning due to extensive conjoining; a single fused head and thorax, and limited fetal movement as was seen in our case. due to the monoamniocity of the conjoined twins, a single yolk sac alongside a single crl and normal fetal heart were observed at - weeks of gestation in our case; mimicking a singleton pregnancy and substantial missing of the second fetal heart (figure a). when the second ultrasound scan was performed at weeks days of lmp in our case for nt measurement, the operator reported a fetus with normal fetal heart, increased nt, non-visualized nb, and herniated mass at the ventral abdominal wall, but yet to notice the second fetal heart and fused brains. following the detection of the aforementioned anomalies, a thorough evaluation of the fetal thorax and cranium via scanning the entire uterus both in a longitudinal and transverse approach could be helpful in revealing two separate hearts, fused brains, and duplicated extremities, leading to the accurate diagnosis of cts. increased nt, cystic hygroma, and abdominal wall defects are the most common findings in conjoined twins ( ). currently, certain congenital fetal anomalies are diagnosed even before the twentieth week of gestation with the use of high-resolution ultrasound equipment, but without following a standardized approach to fetal ultrasound and in case of lack of suspicion to any abnormal condition, misdiagnosis may happen ( , ). the final ultrasound scan was performed at - weeks of ga in our reported case. the diagnosis of cephalothoracopagus cts was made by finding one shared placenta and umbilical cord, two fused brains without separating bony skull, two deformed spinal columns, one common thoracic cage with two separate beating hearts and one stomach, two separate sets of lower and upper extremities, and two separate pelvises. one of the twins had cystic hygroma in the posterior neck. the estimated ga based on both twines’ approximate crl was weeks days (figures b, c and d). the next step after diagnosis of conjoined twinning is a prognostic assessment to propose timely medical termination of pregnancy in case of non-viability and prevent complicated surgical delivery. in cephalothoracopagus cts, due to the fusion of the heads and abnormal arrangement of the superior central nervous system, no attempt at surgical separation should be considered and the prognosis is very poor ( ) . we arranged a medical pregnancy termination accordingly. the recurrence risk for conjoined twins appears to be negligible ( ). conclusion in cephalothoracopagus twining a single yolk sac alongside a single crl and normal fetal heart at - weeks of gestation may mimic a singleton pregnancy and lead to missing the second fetal heart and fused brains without applying a standardized scanning of the entire uterus both in a longitudinal and transverse approach. a high level of concerns may raise for conjoined cephalothoracopagus twinning in case of finding a single fetal pole with an irregular body outline and a disproportionally large head in the presence of two separate fetal hearts in early pregnancy. two fused heads with two brains and two sets of lower and upper extremities do confirm the diagnosis. acknowledgments the authors would like to thank all those who helped them writing this paper. conflict of interest authors declared no conflict of interests. references . pajkrt e, jauniaux e. first‐trimester diagnosis of conjoined twins. prenatal diagnosis: published in affiliation with the international society for prenatal diagnosis. sep; ( ): - .

), joseph buschman notes that thomas jefferson in and james madison in stressed the importance of newspapers and popular information for a liberal democratic government (p. ). he regrets that in library information science (lis) “democratic theory is an unfinished, truncated idea remaining at its jeffersonian/madisonian beginnings” (p. ), cites a wide range of authors as evidence of a chronic collective failure to develop “democratic theory” in lis, and concludes with a forceful demand that “lis must ask itself the question where it stands in this configuration and in relation to democracy” (p. ). buschman appears to assume (if i have understood the complex language of the article correctly) that there is an essential (meaning inherent) mutual relationship between democratic theory and lis. i suggest that there is an different and simpler explanation. when library systems and resources (or any other technologies) are deployed a socio- technical system is created. the “socio” component is shaped by the cultural context in which the technology is deployed, so library service would be democratic only accidentally through the happenstance of deployment within a democratic situation. it is widely accepted that accessible public libraries with liberal collection development practices are important for the health of democratic political systems. but so is oil. more to the point, effective library services are also important for non-democratic political regimes. lenin and his wife, n. k. krupskaya, herself a librarian, thought so. mussolini’s minister of education was enthusiastic about the role of public libraries in evolving a new fascist culture, and the nazis had a vigorous and well-known interest in collection development. part of the problem in philosophical writings about libraries has been a failure (reflected in danton’s famous article of ) to distinguish between philosophical analysis (rigorous critical thought) and a philosophy (a set of motivating beliefs, concepts and values). the latter always pervades library service and it is not necessarily democratic. different political regimes have different social agendas, so lis will be differently deployed. lenin wrote: “but we must build our own library–a library of a different kind, more in keeping with our socialist way of life.” (quoted in simsova ( , ). there are, i submit, two reasons for the lack of democratic theories of lis. first, the assumption that lis is essentially democratic has been explicitly refuted in at least one introductory lis textbook (e.g. buckland , - ). second, the general lack of developed buckland. democratic theory in library information science. jasist : . democratic theories of lis (as distinct from the democratic uses of lis) in the lis literature, as documented by buschman, implies that personified lis has indeed revealed where it stands: the evidence indicates that writers have found it to be an unproductive line of inquiry. abandoning the notion of a democratic theory of lis would not end the possibilities for fruitful inquiry. there is ample scope for more work on the democratic uses of lis--and if this is what buschman meant, i agree with him. there is also, as i have suggested elsewhere (buckland, , - ), scope for examining whether library and other information and communication services are inherently subversive because they tend to lead to new ideas, but subversion is not always democratic in tendency. references buckland. m. k.

it did not address the status of those who had received them but nonetheless had their supposed appointments nullified. jefferson’s nullification strategy, and the reaction to it, warrants further scrutiny, primarily because both have long been obscure and misunderstood. one might suppose that jefferson treated the vast bulk of midnight appoint- ments as nullities because he thought they had never been consummated. perhaps he thought something had arrested their completion, like non-deliv- ery of commissions. yet there is no theory of appointment that could have sanctioned his course in . recall that he recess-appointed justices of the peace, including those who had received a commission, meaning that he treated delivery as irrelevant. we are drawn to the question of whether he differentiated those who received commissions and those who did not because jefferson, in and mcconnell, supra note , at . see letter from thomas jefferson to george hay (june , ), in the works of thomas jefferson, supra note , at n.i;

( ) after the senate consents, but prior to commissioning; ( ) when a commission is signed or sealed; ( ) when a commission is delivered to the appointee; and ( ) when an individual accepts an offer of appointment. this part focuses on the appointment of senate-confirmed individuals, with little discussion of recess appointments and unilateral appointments to inferior offices. a. by the advice and consent of the senate some might suppose that the constitution creates a default rule of auto- matic appointment. under this theory, while nomination rests solely with the president, an appointment results automatically from the joint action of the president and the senate. in particular, the president’s “action” of keep- ing the nomination before the senate (i.e., not withdrawing the nomina- tion), combined with the senate’s consent, results in an appointment to office. just as the house and senate, acting together, pass bills, perhaps the president and the senate, acting together, appoint officers. this rule is sub- ject to the exceptions found in the constitution, namely the president’s abil- ity to appoint during a senate’s recess, and congress’s ability to vest unilateral appointment authority over inferior officers. to make this automatic appointment theory concrete, consider a scena- rio: the president nominates a person to serve as an article iii judge. the senate considers the nominee and advises and consents to her appointment. as soon as the senate supplies its advice and consent, the appointment is complete because under the automatic appointment theory the constitution provides that the appointment vests when the senate consents. while the president must still commission the new judge (because the constitution requires as much), the appointment is already made. had john marshall endorsed the automatic appointment theory, his argument that william marbury had been appointed would have been short and sweet. he might have said that president john adams nominated and the senate consented, thereby appointing marbury and the others. yet mar- shall never made the assertion, much less discussed this possibility. had he u.s. const. art. ii, § , cl. . id. u.s. const. art. ii, § , cl. . id. id. u.s. const. art. ii, § , cl. . \\jciprod \productn\n\ndl\ - \ndl .txt unknown seq: -nov- : n o t r e d a m e l a w r e v i e w [vol. : wished to do so, he might have cited portions of the federalist. when “pub- lius” spoke of the appointment power as confided “jointly” in the senate and president, perhaps he endorsed the automatic appointment theory. some of jefferson’s critics pressed the theory, insisting that the justices of the peace were appointed on march , when the senate consented. as one put it, “the concurrence of the president and the senate in naming to office, complete the act of appointment.” the detractor added that the president had to commission those whom “he finds on the records of the senate to have been appointed.” while jefferson’s critics spoke in the context of a partisan row, others made similar claims at a time when they had no stake in the justice of the peace controversy. in , a court martial sentenced richard hunt to death. hunt complained that the proceedings were invalid because, among other things, members of the court had never received their commis- sions and hence were unable to conduct a court martial. president john adams sought the advice of members of his cabinet. the treasury secretary, oliver wolcott, claimed that the concurrent act of the senate and the presi- dent constituted an appointment. timothy pickering, who as secretary of state was charged with affixing the seal to civil commissions, agreed that appointments automatically vested when the senate consented. so at least two members of the adams cabinet believed that the senate’s consent com- pleted the appointment, with no further act necessary on the president’s part. and while there was no consensus as to the precise moment of appoint- ment, there was agreement in the cabinet that the court martial judges had been appointed even though they lacked commissions and even though none were prepared. though the episode occurred less than two years before jefferson’s actions in the spring of , no member of the adams the federalist no. , at (alexander hamilton) (garry wills ed., ). no. xvi, addressed to the president of the united states, courier of n.h., dec. , , at ;

[the presi- dent] may withhold or cancel it at pleasure . . . .” the point would stick with jefferson, for in he continued to insist “if there is any principle of law never yet contradicted, it is that delivery is one of the essentials to the validity of a deed.” even if signed and sealed, “as long as it remains in the hands of the party himself, it is in fieri [pending] only, it is not a deed, and can be made so only by its delivery.” though marbury and his fellow applicants rejected jefferson’s version of the delivery theory, the fact that they sought commissions and had never tried to assume office without them one might characterize the delivery theory as a subset of the commission theory if one believed that the president does not actually commission anyone until and unless the potential officer receives the commission. under this theory, signing and sealing a com- mission does not actually satisfy the commission duty of the constitution. there is much to be said for this understanding of the duty to commission because it is hard to see how anyone benefits from a constitutional obligation to sign and seal a document that is never actually given to the officer. see infra text accompanying notes – . for our purposes, it does not matter whether one characterizes the delivery theory as a separate appointment theory or merely as a subset of the commission theory discussed in supra section ii.c. marbury v. madison, u.s.

(french); treaty of amity and commerce, u.s.- neth., oct. , , stat. (dutch); a treaty of amity and commerce, u.s.-prussia, july, aug. & sept. , stat.

the constitution says nothing suggesting that a pardon must be reduced to writing, much less that it must be delivered. indeed, attorneys general have long endorsed the idea of an implied or constructive pardon. in , the question of when a pardon vests resurfaced. two days before christmas, george w. bush signed and sealed a “master warrant” that purported to pardon isaac robert toussie, a convicted felon. within a day, the president learnt that toussie’s father had contributed to the repub- lican party. on christmas eve, bush “revoked” the pardon. the department of justice apparently concluded that the pardon had not vested because no pardon had been delivered to toussie. some com- mentators, citing wilson, agreed. despite the sense that president bush had “revoked” the pardon, there was no revocation as much as there was a decision not to complete the process of granting a pardon. after all, under wilson, no pardon was final until delivery and acceptance. one commenta- tor suggested that there had been a long practice of presidents revoking com- pleted pardons. others disagreed, noting that president bush had a signed a document that declared that the president “hereby grant[s] full and unconditional par- marshall seemed moved by the fact that a court could not take judicial notice of a private pardon unless it was brought to its attention. see id. while that may be true, it hardly matters for when the pardon vests. it surely does not show that delivery is necessary for the pardon to vest. opinions of the attorneys general endorsed the concept of implicit or constructive pardons, relying upon english jurists. see effect of a promotion on a suspended, passed midshipman, op. att’y gen. , ( ); court martial—pardon, op. att’y gen. , ( ). the general idea is that if an offender is ordered to do something inconsistent with his or her potential prosecution or conviction, etc., the official so ordering has pardoned the offender, albeit implicitly or constructively. hence if the president ordered a federal warden to release an inmate who still had time left on his sentence, the order should be understood, at the very least, as a remission of that inmate’s remaining sentence. more generally, one might suppose that if the president publicly declares in a speech that he “hereby pardons” various offenders for their offenses, that would be a pardon. again, nothing in the constitution specifies that pardons must be reduced to writing. see jeffrey crouch, the toussie pardon, “unpardon,” and the abdication of responsibility in clemency cases, congress & presidency , ( ). see david stout & eric lichtblau, pardon lasts just one day for man in fraud case, n.y. times, dec. , , at a . see id. at a . see, e.g., george lardner jr., a test of the power to unpardon, wash. post, jan. , , at a . see p.s. ruckman, jr., can a president revoke a pardon he has granted?, pardon power (dec. , ), http://www.pardonpower.com/ / /can-president-revoke- pardon-he-has.html. \\jciprod \productn\n\ndl\ - \ndl .txt unknown seq: -nov- : ] t h e a p p o i n t m e n t a n d r e m o v a l o f w i l l i a m m a r b u r y dons to the following named persons,” including toussie. furthermore, the administration had called to convey news of the pardon. these com- mentators argued that the pardon had been delivered orally and had been accepted (by either toussie or his attorney). for all these reasons, some believed that the pardon had vested and could not be revoked. others noted that neither delivery nor acceptance was necessary, pointing out that presi- dents previously had issued pardons benefitting the dead, a context where delivery and acceptance is generally impossible. under the discretionary theory, toussie’s case was somewhat easy. the constitution does not specify when a pardon vests, leaving it to the president to decide. president bush could have made a pardon vest prior to delivery, with delivery, upon acceptance, or after certain conditions were satisfied (say a public apology and restitution). the language of the master warrant sig- naled that bush unconditionally pardoned toussie via the warrant itself because it stated that it constituted a pardon. that the department of justice never prepared or delivered an individualized pardon to toussie was irrele- vant. while toussie might have preferred a pardon in this form, the master warrant was a wholly adequate pardon. does a constitutional actor have complete discretion as to the exercise of her constitutional powers? no. an agent given power to do x must comply with the constraints, express and implied, the principal has imposed on the agent. because some limits are implied, a mere reading of the grant of power may convey an inaccurate sense of the agent’s authority. for instance, though the federal courts have judicial power to decide cases, they cannot decide cases by reference to which party is wealthier or has a more congenial political ideology. those bases cannot be relevant in a system where justice is supposed to be blind to party attributes. nor could a federal judge decree that a trial by combat would decide a case. by the late eighteenth century that method of resolving judicial disputes generally was forbidden to anglo-american jurists. accordingly, any claim about the proper means of exercising some power must be based not only the constitution’s text but also on a contextu- ally-sensitive understanding of the extant practices. had the constitution been enacted in the fourteenth century, perhaps article iii judges could decide cases by reference to who survived a trial by combat. the text and history of the appointment power leads me to conclude that the president enjoys tremendous discretion in the manner and timing of appointment because there are very few express constraints and seemingly few implied constraints. with respect to the type of opinions that courts issue (majority vs. seriatim) and with respect to when pardons vest, i am similarly confident that the relevant actors had discretion. brian c. kalt, once pardoned, always pardoned, wash. post, jan. , , at a ; see also harlan j. protass, signed, sealed, delivered, but not yours, chi. trib., jan. , , at c . kalt, supra note , at a ; protass, supra note , at c . see protass, supra note , at c . \\jciprod \productn\n\ndl\ - \ndl .txt unknown seq: -nov- : n o t r e d a m e l a w r e v i e w [vol. : in sum, when the constitution grants powers without specifying the mechanisms for their exercise, the institution empowered generally may decide the means of implementing the power. this discretion extends to the form the exercise of power will take and when the power will be exercised. at the same time such discretion is subject to express and implied con- straints, meaning that the institution does not necessarily have absolute dis- cretion as to the means of that power’s exercise. c. restrictions on the rule of appointer discretion as noted, sometimes the constitution constrains the manner in which a power may be exercised. to present a bill to the president, the house and senate must first pass a bill with the same text. to make a treaty, the president must first receive the senate’s consent. courts must have a justi- ciable case or controversy prior to exercising the judicial power. the general rule of appointer discretion is subject to its own set of con- straints. first, while the senate is in session, the president cannot appoint individuals to non-inferior offices unless he first secures senate consent. for such offices, there is a required sequence because under the appoint- ments clause, the senate’s consent is clearly an ex ante constraint on appointments and not an ex post means of ousting people from office. second, the president generally cannot appoint unless there is a preex- isting office created by congress. the appointments clause refers to offices “established by law,” a phrase that suggests that though the president appoints, only congress may create the offices via laws. indeed, that has been our practice from the constitution’s inception. the only exception to this rule is a curious one: the president has long created foreign diplomatic postings, such as the ambassador to france, without the assistance of con- gress. even for such offices, the senate must provide its advice and con- sent prior to appointment, at least while it is in session. a third constraint on appointment discretion is implied. as suggested earlier, certain people cannot be appointed without their acceptance of the office. in particular, it seems clear that no member of congress can be appointed to an executive or judicial office without her consent. the incom- patibility clause signals that no attempted unilateral appointment of a sitting u.s. const. art. i, § , cl. . u.s. const. art. ii, § . id. recently professor matthew stephenson has argued that senate consent can be implied and need not be express. see generally matthew c. stephenson, can the president appoint principal executive officers without a senate confirmation vote?, yale l.j.

(“[n]o person holding any office under the united states, shall be a member of either house during his continuance in office.”). typically the case for an implied prohibition on office holding across the judicial and executive departments rests on the supposedly longstanding practices of the branches. for discussions of this view, see calabresi & larsen, supra note , at – . my esteemed colleague, john harrison, brought this possibility to my attention. \\jciprod \productn\n\ndl\ - \ndl .txt unknown seq: -nov- : n o t r e d a m e l a w r e v i e w [vol. : year. likewise, maybe the president cannot appoint conditional upon the occurrence of an event, such as the senate’s consent. under this reading of the appointments clause, the power to “appoint” is the power to grant an office in the present; it does not encompass authority to dictate that an appointment will or may vest at some point in the future. to flesh out the contours of these supposed restrictions, consider the organic act. it allowed the president to appoint as many justices of the peace as he thought necessary. rather than acting only at the points in time when he deemed it necessary to appoint new justices of the peace, the presi- dent might want to decree that new appointments automatically vest if cer- tain population thresholds are met. for instance, the president might provide, via executive order, that when a particular threshold had been exceeded, a named person would be a new justice of the peace. yet if the appointing power is a power to vest an office only in the present, the president could not appoint someone to office over time. he would have to take action to appoint as and when he wished to fill an office. perhaps it makes sense to read the power to appoint as something that only may be exercised in the here and now and not over time. reading the appointment power in this way has a salutary effect, because it prevents the current president from deciding personnel matters beyond his term. if the president could use his appointment power to appoint conditionally upon some event far into the future, a sitting president could extend his sway beyond his term in office. for instance, the president would be able to decide, with the senate’s consent, the next occupant of a supreme court seat currently occupied. indeed, a president might even be able to decide the successor to the successor, in much the same way the act of settlement deter- mined succession for the english crown. despite some reasons to read the appointment power narrowly, the bet- ter view is that the president can use that power to decide that appointments will vest in the future. to begin with, there are other powers of government that clearly have effect in the future, suggesting that there would be nothing untoward with understanding the appointment power as permitting condi- tional appointments. when congress exercises its lawmaking powers, it cre- ates laws, some of which only take effect in the future, typically upon a certain date. hence the legislative power encompasses the ability to make rules that do not take effect immediately. the president has similar powers. using the pardon power, the presi- dent can issue conditional pardons that only take effect if individuals take particular actions, such as admitting guilt, laying down arms, paying a fine, etc. this means that the pardon power includes authority to extend for- giveness in the future, upon the satisfaction of conditions. act of feb. , , ch. , stat.

( how.) , ( ). but le baron also declared that the appointment was complete after the commis- sion was signed and sealed. id. the two statements can be squared if one supposes that one can be appointed to office without necessarily being able to function in it. in other words, the court might have supposed that while the president appoints, congress can prevent appointees from functioning in office. an early twentieth-century case, glavey v. united states, suggested that the appointment might not be complete until a required oath was taken, thereby hinting that the president could not unilaterally appoint at least as to such offices. u.s. , ( ) (declar- ing that an appointment was “complete, at least, when [an individual] took the required oath and transmitted evidence of that fact to the secretary”). \\jciprod \productn\n\ndl\ -

gero hütter for his discovery that a bone marrow transplant could, it seems, cure a person of hiv. the german hematologist’s findings raised hopes for a new therapeutic treatment, but the shortage of tissue-matched donors has prompted some researchers to apply the lessons learned to new techniques. the hiv-resistant bone marrow donor in hütter’s study carried a rare mutation in the gene encoding c-c chemokine receptor type , or ccr , a surface protein essential for helping hiv attach and infect healthy cells (n. engl. j. med. , – , ). the absence of this molecular portal makes infection nearly impossible. however, individuals with the ccr mutation are rare, and their bone marrow is not always a good match for all recipients. to emulate the protection of this mutation, several research teams are devising ways to downregulate the expression of ccr so that hiv does not recognize and invade sensitive cells in susceptible individuals. one line of attack involves rna interference. last month, for example, irvin chen and his colleagues at the university of california–los angeles school of medicine reported that short hairpin rna could successfully knock down ccr expression in human induced pluripotent stem cells (hum. gene ther. doi: . /hum. . , ). chen, backed by a $ million grant from the california institute for regenerative medicine (cirm), has now partnered with the tuscon, arizona–based biotech startup calimmune to develop therapies based on the approach. another strategy takes advantage of a newly developed technology based on zinc finger nucleases. with this approach, pioneered by sangamo biosciences of richmond, california, engineered enzymes make precise cuts in the genome to disrupt gene function. in , carl june’s team at the university of pennsylvania in philadelphia used zinc finger nucleases to disrupt ccr expression in human t cells, which they injected into hiv-infected mice. the gene therapy lowered viral loads and increased t cell counts in the mice (nat. biotech. , – , ). sangamo, in collaboration with june, has since started extracting mature t cells from hiv-positive individuals, knocking down expression of the ccr gene with zinc fingers, and then re-infusing the cells back into the blood. preliminary results from their first patient indicate that the modified cells are tolerated and persist at stable levels. mighty marrow the t cell approach, however, offers only a treatment—not a cure. so other researchers are focusing instead on altering bone marrow stem cells to provide an everlasting resistance to hiv. last year, cirm funded a team led by john zaia at the city of hope in duarte, california, in collaboration with sangamo, to start pursuing preclinical research applying the same gene therapy tactic in bone marrow. jerome zack of the university of california- los angeles aids institute notes that bone marrow stem cell therapy has the advantage of potentially lasting a lifetime, unlike gene therapy aimed at t cells, which must be repeated over and over again after the mature immune cells die out. what’s more, says zack, who is not involved in these studies, bone marrow transplants should help achieve higher cell counts. “we do not lack ways to attack hiv,” says david strayer, a virologist at thomas jefferson university in philadelphia. “we lack ways to deliver genes adequately.” a potential obstacle to ccr -based gene therapy is that the protein is not the only receptor recognized by the virus—some viral strains bind the cxcr chemokine receptor instead. so june and his colleagues are also developing zinc finger nucleases that target cxcr . however, some scientists have increased concerns about this approach’s safety, because the receptor may have an important role in healthy cells to attract white blood cells to sites of inflammation or injury. “the problem is that [cxcr ] may be more important to the cell for its normal functions than ccr ,” says ramesh akkina, who studies hiv gene therapy at colorado state university in fort collins. what’s more, even strains that normally rely on ccr can evolve to use cxcr instead. instead of focusing solely on these receptors, zaia also recently completed a phase trial of an hiv gene therapy technique involving three genes—two that interfere with viral replication and one that blocks ccr . reporting last month, zaia’s team showed that patients with aids-related lymphoma expressed the modified genes in their blood and showed no signs of short-term toxicity (sci. trans. med. , ra ).

between the mitochondria and the rest of the cell. in its open state vdac exhibits high conductance and selectivity for anions that facilitates the passage of adp, atp, and other metabolites. at increased voltages (> mv) vdac switches to lower conducting states, termed as ‘‘closed’’ states. closed states are cation-selective and impermeable for atp. the voltage-induced transition from the open to closed states is referred to as voltage-gating. although it is well established that vdac voltage-gating in- volves large structural rearrangements, the precise molecular mechanism of this process is still under debate. we investigated vdac voltage-gating by sys- tematically titrating vdac charge residues and by using thermodynamic and kinetic approaches to study opening and closing of the channel. all the models proposed so far agree that n-terminal region plays a key role in vdac voltage- gating. according to the original idea, the n-terminal region is a part of a mo- bile voltage sensor domain, which slides in and out of the channel lumen in re- sponse to the applied voltage. the alternative models consider independent movement of the n-terminal region upon gating. in order to test the role of vdac n-terminal region in voltage-gating, we engineered a double cys mu- tant of murine vdac that cross-links the a-helix to the b-strand of the pore wall. the cross-linked vdac reconstituted into planar lipid membranes exhibited typical voltage gating, which suggests that the n-terminal a-helix is located inside the pore of vdac in the open state and remains associated with the pore wall during voltage gating. our findings support a model where b-bar- rel is not rigid but undergoes a conformational change that leads to a partial constriction upon transition to the closed states. -pos board b novel mechanism of mitochondrial respiration control through competition between hexokinase- and tubulin for vdac binding kely l. sheldon , coert j. zuurbier , sergey m. bezrukov , tatiana k. rostovtseva . the natl. institutes of health, bethesda, md, usa, university of amsterdam, amsterdam, netherlands. the voltage dependent anion channel (vdac) is involved in regulation of me- tabolite flux across the mitochondrial outer membrane (mom). hexokinse ii (hk ) is known to bind the mom where it phosphorylates glucose into glucose- -phosphate (g p). high expression of hxk is a common phenotype of many cancers, where its concentration can be times of that in noncan- cerous cells, and is implicated in the warburg effect. it is believed that vdac serves as a hxk binding site in the mom. the amino acid n-ter- minal sequence of hxk is responsible for mitochondrial binding and, when conjugated to tat (tat-hk ), binds to mitochondria with higher affinity than native hxk , causing hxk detachment. we have previously found that dimeric tubulin reversibly binds and partially blocks vdac inhibiting me- tabolite flux across the mom. now we show that this binding can be attenuated by tat-hxk peptide as well as by full length hxk . we have found that tat-hxk and recombinant full length hxk inhibit tubulin blockage of vdac reconstituted into planar lipid bilayers without altering characteristic channel properties such as single channel conductance and selectivity. binding of hxk to vdac is verified by the generation of high-frequency excess cur- rent noise without channel closure. hxk bound to vdac prevents subse- quent tubulin binding, but only when added before tubulin, and inhibits tubulin-induced vdac blockage in a dose dependent manner. moreover, g p, which is known to cause hxk detachment from the mom, fully re- verses the inhibition of tubulin-vdac binding. this suggests that hxk de- tachment from vdac (and hence the mom) is caused by a hxk conformational change upon g p binding. thus we propose a novel mecha- nism of mitochondrial respiration control in cancer cells through the competi- tion between hxk and tubulin for vdac binding.

revealed mcu as the pore forming domain and micu as a critical ca þ-sensitive regulator of the mitochondrial ca þ uniporter. how- ever, the exact role of micu in ca þ transport remains to be addressed. our previous studies showed that prolonged down-regulation of micu in hela cells (shmicu ) promotes mitochondrial ca þ uptake at low [ca þ ], which unexpectedly, fails to effectively increase matrix [ca þ ]. to determine the source of discrepancy between the mitochondrial ca þ uptake and the ma- trix [ca þ] phenotypes, first we simultaneously monitored ruthenium red- sensitive clearance of added ca þ from the cytoplasm and the corresponding matrix [ca þ] response in permeabilized shmicu cells. under conditions of similar cytoplasmic ca þ clearance, shmicu cells showed a smaller matrix [ca þ ] increase than the control, indicating enhanced buffering of ca þ in the matrix. enhanced ca þ binding in the matrix likely reflects alkalinization and enhanced phosphate transport. to test if upregulation of ca þ buffering is di- rectly linked to micu depletion, we also assessed mitochondrial ca þ han- dling after hr silencing of micu (simicu ). in simicu cells both mitochondrial ca þ uptake and the matrix [ca þ ] rise were effectively stimu- lated at low ca þ levels. thus, upregulation of matrix ca þ buffering seems to be a component of an adaptive response to sensitization of mitochondrial ca þ uptake in shmicu . the adaptive response is likely to be important to attenuate some micu -depletion induced cellular impairments that we found to manifest as attenuated mitochondrial atp production and cell proliferation. -pos board b micu -dependent threshold and cooperativity of mitochondrial ca d uptake in the liver györgy csordás , erin l. seifert ,

our previous studies showed that prolonged down-regulation of micu in hela cells causes lower threshold and decreased cooperativity of mitochondrial ca þ uptake. to study the functional significance of the effects of micu we used hepatocytes harvested from the liver of mice exposed to in vivo silencing ( weeks). silencing of micu or mcu resulted in > % decrease in their respective mrna levels. silencing of micu caused a left- ward-shifted dose response and decreased cooperativity of mitochondrial ca þ uptake in both permeabilized and intact hepatocytes. by contrast, silenc- ing of mcu resulted in slower ca þ uptake in the entire range of ca þ concen- trations without change in threshold. mitochondrial respiration and cellular atp content were unaffected in media containing both glycolytic and mito- chondrial fuels in either micu or mcu-deficient hepatocytes. however, si- lencing of micu caused an augmented loss of atp when the cells were confined to oxidative metabolism and an enhanced sensitivity to mitochondrial ca þ overload and permeabilization. during stimulation with vasopressin, a ca þ mobilizing hormone, both micu and mcu-deficient cells displayed an attenuated mitochondrial matrix [ca þ ] increase and stimulation of respira- tion. collectively, these results show that keeping the gate of mcu closed by micu at low [ca þ] is required to maintain healthy mitochondria, and micu -mediated control of mcu (cooperativity?) is required to support the propagation of short-lasting calcium spikes and oscillations to the mitochondria and the ensuing physiological stimulation of oxidative metabolism. -pos board b targeting mcl- and bak as a therapeutic tool to selectively induce apoptosis in hepaptocellualr carcinoma nima niknejad, soumya sinha

anesthetics (va) are ion channels. the mechanism of volatile anesthetic action is not completely understood. identify- ing the molecular pathway for drug binding is crucial to understand the effect of va on voltage gated sodium channels. we use molecular dynamics simula- tions to identify the binding sites for a hydrophobic general anesthetic isoflur- ane, on voltage gated bacterial sodium channel nachbac. apart from the voltage sensing domain (s -s ), linker and the pore domain (s -s ), bacterial sodium channels also have fenestrations, which provide a hydrophobic tunnel through the lipid-embedded portion of the channel to the central cavity, where the known local anesthetic site is located. unbiased ‘‘flooding’’ simulations were performed on the activated open confirmation of nachbac. we per- formed a cluster analysis to identify all the possible binding sites of isoflurane. the three most important ones among them are: a region near the selectivity filter, called the extracellular site, a region near the s -s linker, called the linker site, and a region within the cavity, called the cavity site. the most important observation is that isoflurane enters the central cavity through the fenestrations. free energy perturbation method was employed to calculate the binding affinities of isoflurane for each of these sites. we also studied the interactions between isoflurane and the amino acids in these three binding sites. -pos board b a key gating charge interaction required for slow inactivation of the navab bacterial sodium channel tamer m. gamal el-din, todd scheuer, william a. catterall. university of washington, seattle, wa, usa. bacterial voltage-gated sodium (nav) channels are considered an ideal model for structure-function studies. the elucidation of the crystal structure of the bacterial channel navab (payandeh et al., nature , - , ) opened an avenue to understand electrical signaling in excitable cells at the structural level. navab expressed in hi insect cells as for structural studies has unusually negative voltage-dependent activation (va ~ mv). navab also has three phases of inactivation, a biphasic early inactivation process (t ~ ms, t ~ . s, at � mv) followed by an unusually strong and use-dependent slow-inactivation process. to search for the molecular basis for negative activation and slow inactivation of navab, we mutated the outer- most gating charge partner in the s segment, asn , to lys. this mutation shifted the activation curve ~ mv toward more positive potentials. surpris- ingly, it also completely abolished use-dependent slow inactivation. we showed previously that the equivalent residue in nachbac (asp ) interacts with the r gating charge in the s segment during activation using the disul- fide locking method (decaen et al, pnas ( ) - ). to test whether this interaction between r and n was critical for slow inactivation, we mutated navab r to cys. the resulting mutant navab_r c also had positively shifted channel activation (þ mv) and no use-dependent slow inactivation. the fact that these reciprocal mutations have the same functional effects suggests that interaction between r in the s segment and n in the s segment is an important link that stabilizes the activated state of the voltage sensor and triggers the slow inactivation process. -pos board b computational study of the prokaryotic sodium channel karen m. callahan, benoit roux. university of chicago, chicago, il, usa. ion-selective voltage-gated ion channels allow ions of a specific element or set of elements to pass, but exclude other ions. recently, the crystal structure of navab was published (payandeh et al ( ) nature , ), giving an un- ambiguous picture of the structure of the sodium channel selectivity filter (sf) of the prokaryote arcobacter butzleri. the filter is much wider than that of the narrow, carbonyl-lined potassium channels, allowing ions to penetrate with minimal dehydration, multiple pathways, and even to pass each other. previous computational studies have attempted to explain sodium selectivity, and claimed consensus (corry and thomas ( ) jacs , , furini and domene ( ) plos , e ). experimental ion selectivity determina- tion from pore-only constructs of a sodium channel with the same sf sequence shows stronger ion selectivity from reversal potential than from the ratio of the fluxes of sodium and potassium (shaya et al ( ) pnas , ), but selectivity, na þ/kþ, was still less than five. simulations based upon the closed-pore crystal structure could not determine selectivity directly from con- duction. to investigate this issue, we first calculated multi-ion potentials of mean force in the selectivity filter of pore-domain-only navab with an ex- tended equilibration period, and a replica-exchange molecular dynamics scheme, which allows for improved sampling. we then explored the non- equilibrium conduction of sodium and potassium in the presence of an applied electric field through a model navab pore truncated to mimic the conformation of the open pore. we also present multi-ion pmf calculations to illustrate similarities and differences between this model and the intact pore. when taken together, these two methods provide complementary views of ion selectivity and conduction based upon the conformation of the navab crystal structure of payandeh et al ( ). -pos board b volatile general anesthetic interactions with a bacterial sodium channel annika f. barber , srinivas g. raju , david lebard , vincenzo carnevale , michael l. klein , manuel covarrubias . thomas jefferson university, philadelphia, pa, usa, temple university, philadelphia, pa, usa. general anesthesia results from complex interactions involving ion channels in the brain. voltage-gated ion channels are modulated by halogenated inhaled general anesthetics, however the drug-channel interactions are generally believed to be non-specific making it difficult to investigate the molecular mechanisms of anesthetic action. we find, however, that the bacterial sodium channel nachbac exhibits differential regulation by different general anes- thetics, suggesting that there may be specific interactions. molecular dynamics (md) simulations have identified several possible binding sites for isoflurane in the nachbac channel structure. here, we have characterized the affinity, occu- pancy and hydrogen bonding for these sites and identified key interactions. in addition, experimental evidence suggests that both isoflurane and sevoflurane have dual actions on nachbac, possibly involving action at two different sites. consistent with pore block, sevoflurane accelerates the decay of the current ( % faster at . mm sevoflurane) but, at the same time, increases the peak current ( % increase with . mm sevoflurane), which argues against the blocking mechanism. we hypothesize that an additional mechanism involving a distinct site is necessary to explain the latter effect. we are currently employ- ing md simulation and structural modeling combined with mutagenesis and electrophysiology to test this two-site hypothesis and investigate the molecular mechanisms of these opposing effects. supported by ninds f ns (afb) and nigms p gm (mlk). -pos board b polymodal, high affinity actions of m-conotoxins on a bacterial voltage- gated sodium channel rocio k. finol-urdaneta , robert glavica , jeff r. mcarthur , robert j. french . university of calgary, calgary, ab, canada, rmit, melbourne, australia. m-conotoxins (mctxs) are potent blockers of eukaryotic sodium channels, and individual members of the mctx family are highly specific for particular nav isoforms. we have begun to explore mctx interactions with nachbac, a pro- karyotic nav channel closely related to navab, whose crystal structure was re- cently determined (payandeh et al, , nature : ). our data reveal actions on both ion conduction and gating, consistent with polymodal actions on the pore domain. under voltage clamp, whole-cell currents from nachbac expressed in tsa- cells were reduced, up to nearly complete block, by concentrations in the pm to mm range, for wildtype toxins and derivatives of mctx piiia and kiiia. for wildtype piiia, dose-response data ( . - , nm) yielded the following: ic = . nm; maximal fraction of current blocked = . ; hill coefficient = . . chen & chung ( , biophys. j. : ) predicted an ic of . nm for piiia when the navab channel is occupied by sodium ions. even at very low [piiia] ( pm), the unblocked currents showed increasing rates of inactivation as the peptides were washed in, suggesting a gating mod- ulation, that was not tightly associated with pore block. for mctx piiia ( . nm), or kiiia ( nm), inactivation accelerated by ~ -fold. substitution of key basic residues (piiia-r a and kiiia-k a) reduced blocking potency and decreased the speeding of inactivation to less than -fold. given the remarkably high selectivity and affinity that mctxs show for certain eukaryotic nav channels with highly asymmetric pores, it may seem surprising that they bind to symmetric bacterial nav channels with such high affinity. binding of isoflurane to a bacterial voltage-gated sodium channel: structure and accessibility of distinct interaction sites a key gating charge interaction required for slow inactivation of

open state vdac exhibits high conductance and selectivity for anions that facilitates the passage of adp, atp, and other metabolites. at increased voltages (> mv) vdac switches to lower conducting states, termed as ‘‘closed’’ states. closed states are cation-selective and impermeable for atp. the voltage-induced transition from the open to closed states is referred to as voltage-gating. although it is well established that vdac voltage-gating in- volves large structural rearrangements, the precise molecular mechanism of this process is still under debate. we investigated vdac voltage-gating by sys- tematically titrating vdac charge residues and by using thermodynamic and kinetic approaches to study opening and closing of the channel. all the models proposed so far agree that n-terminal region plays a key role in vdac voltage- gating. according to the original idea, the n-terminal region is a part of a mo- bile voltage sensor domain, which slides in and out of the channel lumen in re- sponse to the applied voltage. the alternative models consider independent movement of the n-terminal region upon gating. in order to test the role of vdac n-terminal region in voltage-gating, we engineered a double cys mu- tant of murine vdac that cross-links the a-helix to the b-strand of the pore wall. the cross-linked vdac reconstituted into planar lipid membranes exhibited typical voltage gating, which suggests that the n-terminal a-helix is located inside the pore of vdac in the open state and remains associated with the pore wall during voltage gating. our findings support a model where b-bar- rel is not rigid but undergoes a conformational change that leads to a partial constriction upon transition to the closed states. -pos board b novel mechanism of mitochondrial respiration control through competition between hexokinase- and tubulin for vdac binding kely l. sheldon , coert j. zuurbier , sergey m. bezrukov , tatiana k. rostovtseva . the natl. institutes of health, bethesda, md, usa, university of amsterdam, amsterdam, netherlands. the voltage dependent anion channel (vdac) is involved in regulation of me- tabolite flux across the mitochondrial outer membrane (mom). hexokinse ii (hk ) is known to bind the mom where it phosphorylates glucose into glucose- -phosphate (g p). high expression of hxk is a common phenotype of many cancers, where its concentration can be times of that in noncan- cerous cells, and is implicated in the warburg effect. it is believed that vdac serves as a hxk binding site in the mom. the amino acid n-ter- minal sequence of hxk is responsible for mitochondrial binding and, when conjugated to tat (tat-hk ), binds to mitochondria with higher affinity than native hxk , causing hxk detachment. we have previously found that dimeric tubulin reversibly binds and partially blocks vdac inhibiting me- tabolite flux across the mom. now we show that this binding can be attenuated by tat-hxk peptide as well as by full length hxk . we have found that tat-hxk and recombinant full length hxk inhibit tubulin blockage of vdac reconstituted into planar lipid bilayers without altering characteristic channel properties such as single channel conductance and selectivity. binding of hxk to vdac is verified by the generation of high-frequency excess cur- rent noise without channel closure. hxk bound to vdac prevents subse- quent tubulin binding, but only when added before tubulin, and inhibits tubulin-induced vdac blockage in a dose dependent manner. moreover, g p, which is known to cause hxk detachment from the mom, fully re- verses the inhibition of tubulin-vdac binding. this suggests that hxk de- tachment from vdac (and hence the mom) is caused by a hxk conformational change upon g p binding. thus we propose a novel mecha- nism of mitochondrial respiration control in cancer cells through the competi- tion between hxk and tubulin for vdac binding. -pos board b reprogramming of mitochondrial ca d handling in micu -deficient hela cells tünde golenár , györgy csordás , erin l. seifert , cynthia moffat , fabiana perocchi , yasemin sancak , david weaver , vamsi k. mootha , györgy hajnóczky . thomas jefferson university, philadelphia, pa, usa, harvard medical school and massachusetts general hospital, boston, ma, usa. recent studies have revealed mcu as the pore forming domain and micu as a critical ca þ-sensitive regulator of the mitochondrial ca þ uniporter. how- ever, the exact role of micu in ca þ transport remains to be addressed. our previous studies showed that prolonged down-regulation of micu in hela cells (shmicu ) promotes mitochondrial ca þ uptake at low [ca þ ], which unexpectedly, fails to effectively increase matrix [ca þ ]. to determine the source of discrepancy between the mitochondrial ca þ uptake and the ma- trix [ca þ] phenotypes, first we simultaneously monitored ruthenium red- sensitive clearance of added ca þ from the cytoplasm and the corresponding matrix [ca þ] response in permeabilized shmicu cells. under conditions of similar cytoplasmic ca þ clearance, shmicu cells showed a smaller matrix [ca þ ] increase than the control, indicating enhanced buffering of ca þ in the matrix. enhanced ca þ binding in the matrix likely reflects alkalinization and enhanced phosphate transport. to test if upregulation of ca þ buffering is di- rectly linked to micu depletion, we also assessed mitochondrial ca þ han- dling after hr silencing of micu (simicu ). in simicu cells both mitochondrial ca þ uptake and the matrix [ca þ ] rise were effectively stimu- lated at low ca þ levels. thus, upregulation of matrix ca þ buffering seems to be a component of an adaptive response to sensitization of mitochondrial ca þ uptake in shmicu . the adaptive response is likely to be important to attenuate some micu -depletion induced cellular impairments that we found to manifest as attenuated mitochondrial atp production and cell proliferation. -pos board b micu -dependent threshold and cooperativity of mitochondrial ca d uptake in the liver györgy csordás , erin l. seifert , tünde golenár , cynthia moffat , sergio de la

research, mit, cambridge, ma, usa, harvard medical school and massachusetts general hospital, boston, ma, usa. recent studies have revealed mcu as the pore forming domain and micu as a critical ca þ-sensitive regulator of the mitochondrial ca þ uniporter. how- ever, the mechanism of the complex ca þ dependence of the uniporter activity remains elusive. our previous studies showed that prolonged down-regulation of micu in hela cells causes lower threshold and decreased cooperativity of mitochondrial ca þ uptake. to study the functional significance of the effects of micu we used hepatocytes harvested from the liver of mice exposed to in vivo silencing ( weeks). silencing of micu or mcu resulted in > % decrease in their respective mrna levels. silencing of micu caused a left- ward-shifted dose response and decreased cooperativity of mitochondrial ca þ uptake in both permeabilized and intact hepatocytes. by contrast, silenc- ing of mcu resulted in slower ca þ uptake in the entire range of ca þ concen- trations without change in threshold. mitochondrial respiration and cellular atp content were unaffected in media containing both glycolytic and mito- chondrial fuels in either micu or mcu-deficient hepatocytes. however, si- lencing of micu caused an augmented loss of atp when the cells were confined to oxidative metabolism and an enhanced sensitivity to mitochondrial ca þ overload and permeabilization. during stimulation with vasopressin, a ca þ mobilizing hormone, both micu and mcu-deficient cells displayed an attenuated mitochondrial matrix [ca þ ] increase and stimulation of respira- tion. collectively, these results show that keeping the gate of mcu closed by micu at low [ca þ] is required to maintain healthy mitochondria, and micu -mediated control of mcu (cooperativity?) is required to support the propagation of short-lasting calcium spikes and oscillations to the mitochondria and the ensuing physiological stimulation of oxidative metabolism. -pos board b targeting mcl- and bak as a therapeutic tool to selectively induce apoptosis in hepaptocellualr carcinoma nima niknejad, soumya sinha roy, eric knudsen, györgy hajnóczky. thomas jefferson university, philadelphia, pa, usa. in this study we seek to identify novel drug targets to induce apoptosis in he- patocellular carcinoma (hcc) cells thus providing opportunities to develop novel treatments to improve the prognosis of liver cancer patients. several ap- optotic pathways are mediated through cleavage of bid (a bh domain-only, pro-apoptotic protein) to produce truncated bid (tbid). tbid induces apoptosis through induction of outer mitochondrial membrane (omm) permeabilization by activation of pro-apoptotic bak that resides in the omm or cytoplasmic bax. due to its localization, bak can mediate the early phase of the response to tbid. we have recently demonstrated that omm targeting of bak and the sensitivity to tbid-induced omm permeabilization is dependent on

duodeno-duodenal intussusception; gastrointestinal bleed introduction etiologies for gastrointestinal (gi) bleeding commonly include bleeding ulcers, arterial venous malformations, diverticular disease, hemorrhoids, and anal fissures, whereas uncommon causes include meckel’s diverticu- lum and intussusception. typically, conventional diag- nostic modalities such as physical examination, endoscopy, and radiological imaging yield a cause, although occa- sionally surgical intervention is required to obtain a di- agnosis. here, we report the first case of a patient with gi bleeding secondary to duodeno-duodenal intussus- ception caused by a leiomyoma. case a -year-old male presented to the thomas jefferson university hospital in august with a syncopal epi- sode, fatigue, abdominal pain, and dyspnea on exertion. a review of the patient’s records revealed two previous hospitalizations to an outside institution over the prior months for melena and near syncope. a computed tomography (ct) with enterography performed at the outside hospital in november revealed a cm intraluminal mass-like density. an esophagogastroduo- denoscopy (egd) with endoscopic ultrasound was per- formed at that time, which revealed an extrinsic thickened fold of the second portion of the duodenum (d ), con- cerning for a duodenal duplication cyst. fine-needle aspi- ration of the suspected mass revealed normal villous morphology. at the patient’s second presentation to the outside hospital in july , a second egd evalua- tion revealed a bleeding ulcer in the stomach and a repeat ct showed that the duodenal mass had increased to cm. rutgers-robert wood johnson medical school, piscataway, new jersey. department of surgery, jefferson pancreas, biliary, and related cancer center, thomas jefferson university hospital, philadelphia, pennsylvania. *address correspondence to: harish lavu, md, department of surgery, jefferson pancreas, biliary, and related cancer center, thomas jefferson university hospital, walnut street, philadelphia, pa , e-mail: harish.lavu@jefferson.edu ª louis f. chai et al. ;

( ) this definition sounds circular: the reader affirms that characters and situations are authentic if the reader finds them plausible, and in a work of historical fiction, the reader will find plausible those characters and situations that adhere to the reader’s knowledge of the history of the same or similar people and situations as presented in the fictional work. such circular logic may be unavoidable. catherine butler and hallie o’donovan acknowledge the difficulty in determining whether a fictional work achieves authenticity: historical fiction is haunted by the demand for, and the impos- sibility of, authenticity in its representations of the past. the concept of authenticity covers a lot of semantic territory, en- compassing not only the criterion of factual accuracy—that is, of telling it like it is (or was)—but also the questions of who is doing the telling, and how and why. any modern representation of the experiences of those who lived in the past must necessarily be a ventriloquistic performance, given in terms designed to be understood by a modern audience. ( ) determining authenticity requires a more subjective interpretive re- sponse than the effort to determine accuracy. this essay examines the novel’s authenticity: the difficulty in judging the authenticity of wolf by the ears is compounded by the presentation of historic individuals. harriet, narrating between the ages of eighteen and twenty-one, is circumspect, reflective, intent on processing the abundance of advice thrust on her. for the novel to seem authentic, from the very first scene the reader must accept as plausible that har- riet has been tutored sufficiently to compose such a narrative and that jefferson would encourage such private reflections. the histori- cal record remains silent about such crucial possibilities. butler and o’donovan stress “the questions of who is doing the telling, and how and why.” rinaldi chose to depict jefferson and the monticello com- munity through the eyes of a house slave who enjoys privileges alien filling in gaps in the historical record to the slaves who work in the fields, for example, under the sway of a brutal overseer. harriet admits she has never been away from monti- cello except for brief visits “to a neighboring plantation” ( ). the lengthy entries in her private journal highlight the comparative luxury of a slave who seems unaware that other slaves are victims of rapes and beatings and forcibly separated from their own families, while she is granted many months to contemplate the choice—over which she has much control—to leave her family. rinaldi remains true to the testi- mony provided decades later by madison hemings: “my brothers, sister harriet and myself, were used alike. we were permitted to stay about the ‘great house,’ and only required to do such light work as going on errands. harriet learned to spin and to weave in a little factory on the home plantation. we were free from the dread of having to be slaves all our lives long, and were measurably happy. we were always permit- ted to be with our mother, who was well used” (qtd. in gordon-reed, thomas jefferson and sally hemings ). presumably, rinaldi considered the soft focus on slavery that harriet provides a legitimate trade-off for the insights harriet has access to about jefferson and other historically prominent members of jefferson’s extended white family. ideally, when examined in a classroom setting, rinaldi’s novel would be considered in the context of other documents, including madison’s concise recol- lections in his memoir. evaluating authenticity relies upon gap-filling strategies that a reader must devise. because no written testimony by harriet is extant, because jefferson chose silence rather than any acknowledgement of his hemings children, rinaldi’s reader must explain why his speech and her response to him seem plausible, why her personal and moral con- fusion strikes an authentic note. wolf by the ears achieves a convincing degree of cultural authenticity: harriet’s life at monticello falls within the boundaries of the historical record. furthermore, her internal life, her identity formation, achieves a convincing degree of psychological authenticity. this point is especially crucial as the novel engages with this personal dimension of authenticity: whether harriet can remain authentic to herself if she leaves monticello and passes as white. this essay also examines the accuracy of rinaldi’s novel based upon historical documents available to her, as well as evidence from the past two decades since wolf by the ears was published. four historical inaccuracies are identified that bolster harriet’s view of jefferson as a morally centered man whose current political powerlessness provokes her pity: references to her older brother tom, to jefferson’s mentor brian dillon george wythe, to the composition of the declaration of independence, and to the missouri compromise. it would be unrealistic to expect that most readers, especially ya readers, would be capable of identifying the inaccuracies or why they matter. consequently, the novel needs to be approached with guarded skepticism. a reader informed with more historical evidence than the novel provides may question whether jef- ferson deserves harriet’s pity-provoking depiction of him: this essay provides such evidence and expands the ability of rinaldi’s readers to evaluate jefferson’s conduct and its consequences. it is insufficient, though, to assess accuracy simply by noting paral- lels or deviations from the historical record in the novel. the issue of accuracy must be linked to “who is doing the telling, and how and why.” harriet perceives jefferson with a mixture of awe, the godlike former president whose knowledge of the world exceeds that of anyone she knows; pity, over his inability to change cultural norms regarding the treatment of slaves; and exasperation, in regard to his silence on the issue most crucial to her personally—her own paternity. of these three, the affective response that most risks distorting what is known about jefferson is pity. the closure to the novel confirms a sense of jefferson as pitiful and pushes the injustice of slavery out of sight. this essay will consider an alternative ending that rinaldi chose not to construct, one that challenges the implicit emphasis on pity and sentimentality and that is historically based. rinaldi succeeds in avoiding historical anachronism: she does not impose contemporary cultural norms on a society roughly years in the past. she leaves much interpretive room for the reader to determine whether jefferson deserves to be judged harshly. jefferson effectively succeeded in controlling the narrative of his pri- vate life until the end of the twentieth century. wolf by the ears disrupts the narrative jefferson wanted told. “historical novels,” kim wilson states, “holding the peculiar position of being both fiction and fact simultaneously, are effective vehicles to promote values and attitudes pertinent to the formation and perpetuation of a national identity” ( ). despite the four historical inaccuracies that this essay will ex- amine later, and despite harriet’s relatively privileged slave status, the novel’s authenticity implicitly challenges the white supremacist political power structure of the early nineteenth century. despite harriet’s pity- ing perspective, the novel subverts efforts to engage in hero worship of the complex former president and slave owner. filling in gaps in the historical record rinaldi’s reliance upon a young adult narrator and some initial historical points before discussing these four historical inaccuracies and why they mat- ter, this section examines rinaldi’s choice of harriet rather than sally as narrator and indicates that harriet operates as a pawn or by-product within the larger plot of the jefferson-sally hemings relationship. also, certain episodes in the novel that prove to be partially accurate must be analyzed to provide a context for understanding the four inaccuracies. without using the terminology of this essay—accuracy and authen- ticity—rinaldi’s preliminary note to her novel positions herself on the defensive, offers disclaimers: she did not intend to “put down” jefferson, but to depict him as accurately as she could based upon his own writ- ing (x–xi). yet the novel’s display of jefferson’s passivity and duplicity challenges the heroic-ideal conception of him. rinaldi’s preliminary note to her novel also self-consciously explains why she composed her narrative by relying upon harriet’s point of view. of course, as a twentieth-century white woman she does not claim to “know what it felt like to be a slave,” but she understands the concept of alienation based upon her lack of knowledge of her own mother who died when she was born (xi). the author’s response to the historical fact of harriet’s departure from monticello on her own, leaving her family behind, perhaps forever, is “how terrible!” (x), and her novel then justifies why harriet’s decision to leave monticello does not fit the stereotypical flight from slavery to freedom that would be celebrated. but the preliminary note does not explain why rinaldi chose an unusually privileged slave to tell her story, a choice which may upset readers expecting a narra- tive of the dehumanizing realities of slavery. nor does it reflect on her depiction of sally hemings, whose decision to stay with jefferson and whose motivations for urging harriet to leave monticello perplex har- riet. while some readers may consider this relationship romanticized by rinaldi, historical evidence published after wolf by the ears implicitly supports rinaldi’s view. with all the available written documents by—and about—jefferson and absolutely none by sally hemings, not even one letter from her hand, it was inevitable that following the dna studies new evaluations of jefferson’s character would circulate, while sally hemings would remain a mystery to be speculated about. her son madison in his memoirs explains the situation sally dealt with while in france as the servant to jefferson’s daughter maria: brian dillon [d]uring that time my mother became mr. jefferson’s concubine, and when he was called back home she was enceinte [pregnant] by him. he desired to bring my mother back to virginia with him but she demurred. she was just beginning to understand the french language well, and in france she was free, while if she returned to virginia she would be re-enslaved. so she refused to return with him. to induce her to do so he promised her extraor- dinary privileges, and made a solemn pledge that her children should be freed at the age of twenty-one years. in consequence of his promise, on which she implicitly relied, she returned with him to virginia. (qtd. in gordon-reed, thomas jefferson and sally hemings ) annette gordon-reed, who of all historians has been most successful in reconstructing the lives of sally, her siblings, and her children, evaluates sally’s decision, which she made while in her mid-teens and presumably with the guidance of her older brother james who was living in paris at the same time, in training as a chef. (the father of sally and her five siblings, john wayles, was also the father of jefferson’s wife martha, who died prior to jefferson’s sojourn in paris.) having spent her previous years at monticello, sally would have noted the favoritism accorded to hemings females: she “watched every female go to the fields at harvest time, except her sisters, mother, and whatever white females were at the plantation. she learned from all this that, in jefferson’s eyes, she was a female to be protected from certain things, when most women of her same legal status received no protection at all” (the hemingses of monticello ). gordon-reed also speculates on what james and another older brother robert may have thought of her arrangement with jefferson. as the adult children of the same white father, they may have “simply viewed their sister’s connection to jefferson as a predicat- able [sic] event in life as they knew it. . . . and if they had any degree of trust in his [jefferson’s] word—that he was going to stick by his bargain with their sister—she was already better off than their mother who had not obtained freedom for any of her children” (the hemingses of monticello ). gordon-reed speculates further that the jefferson- hemings relationship was monogamous, lasted nearly four decades, and was mutually satisfying. salamishah tillet notes the uniqueness of this interpretation: “ironically, gordon-reed’s historical romance not only challenges those jefferson scholars who have vigorously denied the possibility that jefferson might have coerced hemings, but it is also a radical departure from canonical black feminist scholarship on filling in gaps in the historical record enslaved women, consent, and rape” ( ). such scholarship “suggests that enslaved african american women could not willingly engage in sexual encounters with white men without coercion” ( ). in one extended discussion of rinaldi’s novel, emily honey acknowl- edges the constraints placed upon a young adult author in treating this historic topic: [b]ecause she was writing for a younger audience, [rinaldi] could not be nearly as explicit about sexual matters, or about the power dynamic that would have been involved in any relationship they might have had, topics that might have been too weighty for adolescent readers. it might have seemed better to create a narrative from harriet’s perspective, one that would still deal with the conflicts of her race, parentage, and position as a slave, but would be removed enough from sally and jefferson to avoid confronting the issues head on. therefore, harriet becomes the narrator and the focus, and her relationship with jefferson of primary importance—once again leaving sally rather in the background, overshadowed by the white man who controlled her world. (honey ) in rinaldi’s novel, sally does tell harriet that she negotiated with jefferson while she was a teen in france: she acquired her children’s freedom before they were born, presumably a pre-intimacy promise extracted from jefferson ( , ). in a passage that dovetails with the romantic speculations gordon-reed promotes, rinaldi’s version of sally even asserts, on the day before harriet is to leave monticello forever, that she loved jefferson: “‘that’s why i came back from paris too. no sense lying. didn’t say it was right. just saying i loved him.’ it was the first time she had ever spoken of herself and the master to me” ( ). this is all harriet learns from her mother about the degree and duration of her mother’s intimacy with jefferson. as honey claims, for harriet—and many ya readers—to be more specific would be too “weighty.” yet harriet inquires in her own way on the topic of intimacy between sally hemings and jefferson: harriet’s dialogues with jefferson frame the novel—the first in december and the last in august when she departs from monticello—and thus have prominence of place. rinaldi lowers jefferson’s pedestal by highlighting his indirect manner when speaking to harriet, which veers into dishonesty by his omissions. in the first dialogue, in which harriet carries in a tray of tea while brian dillon jefferson sits writing his autobiography in his “sanctum sanctorum,” the private rooms where he works and sleeps, previously a forbidden zone to harriet, sally is present when harriet asks: “will you put my mama in” your autobiography ( , )? jefferson deflects her questions; he concentrates instead on praising her accomplishments, gifting her with a leather journal (in which she writes the narrative that is this nov- el), and offering advice about writing. this brief exchange highlights one of harriet’s primary concerns: will her mother acknowledge the relationship directly, and will jefferson acknowledge it even indirectly? what harriet does not learn is that the -year-old jefferson ceased composing his autobiography after “sixty-odd pages”: he only included his experiences up until , when he was about to leave paris. brodie proposes one reason why he abandoned his autobiography at this early point in his complex political and personal life: to shield “the most pressing secret of his life” ( ), the beginning of his relationship with sally hemings. jefferson gently instructs harriet: “write down what you see, what is important to you, whether it be the sound of a bird, the snow on the blue ridge, or the taste of your mama’s salmagundi. . . . write down what you feel, harriet. it eases the heart. you will discover that in your own good time” ( ). he could not anticipate either the depth of insight evident in her narratives or her interrogation of his personal choices. jefferson apparently presumed that harriet inherited his own aversion to private revelations. but rinaldi demonstrates a range of influences upon this -year-old woman that trumps the “master’s” habitual denial of self-disclosure. members of both her immediate and extended family instruct her regarding her present identity and whether she should alter that identity by departing from monticello and pass- ing for white. other slaves and a white architect who visits jefferson’s estate to use his library also contribute direct advice to harriet. the interest others take in harriet’s future suggests she is a most fortunate young adult. she’s no holden caulfield, crudely dismissing the guid- ance well-intentioned adults offer; instead, harriet weighs the merits of what she is told, however emotionally unsettling the advice may be. writing in this journal allows harriet her first sustained attempt at self- reflection, a task both assisted and thwarted by the variety of advice from others she must process. the novel’s central plot, in general terms, is one of self-realization, but it unfolds in a hyper-specific, extraordinary historical circumstance. with rare exceptions, the individuals in this novel who move through the main house and over the grounds of monticello are known to filling in gaps in the historical record history, though what we know (or think we know) remains in dispute nearly years later. rinaldi shapes her story with a crowded cast, by necessity: harriet and her three brothers—beverly, madison, and eston; martha randolph, jefferson’s only living child from his marriage, her husband thomas mann randolph, and their sprawling family (eleven children who lived to adulthood, three born after harriet’s birth); other house slaves (such as jefferson’s “body man,” burwell colbert); as well as, of course, harriet’s mother and jefferson; and a variety of visitors, including dignitaries and extended family members. rinaldi does err in claiming that harriet lives on the third floor of the main building ( , – , ). jefferson’s daughter martha and her chil- dren, as well as guests, resided under the same roof as jefferson. for the hemings children to do so would have been an announcement to visitors of sally’s children’s privileged status. in the year that harriet was born, , construction began on the “dependencies connecting the south pavilion with the mansion, . . . joined rooms, which included the kitchen, smokehouse, dairy, and slave quarters” for house slaves (mclaughlin ), and this would be where harriet and her brothers resided. rinaldi’s error does not detract from the overall quality of her novel, as harriet’s movements through the more public rooms of the house tend to be precisely circumscribed. the opening scene does emphasize, appropriately enough, harriet’s trepidation in entering jefferson’s private quarters, at his invitation and accompanied by her mother. further selective attention to rinaldi’s treatment of the historical record must be noted here, if only to test the novel’s accuracy. for example, harriet presents her ancestry, tracing her roots back to her maternal great-grandmother, and she notes that jefferson’s father-in- law (and sally’s father) bequeathed him slaves, including sally and her mother elizabeth ( – ). she recounts the anecdote from of jefferson watching through a telescope as british troops approached monticello, and then escaping on horseback, calm when others may have panicked ( – ). with the first example, which sweeps over many decades, and the second, which provides a close-up of one man’s con- duct at one particular moment, rinaldi moves her narrative forward on firm ground. also, in regard to accuracy, mention of the scornful press reports of the jefferson-sally hemings relationship, which emerged even after harriet’s birth, occurs three times. the novel’s authenticity, rinaldi’s craftsmanship in filling in gaps plausibly, requires more interpretive labor. the reporter responsible brian dillon (or the irresponsible reporter, depending upon one’s view of presiden- tial privacy), james callender, is not named by harriet. she focuses on jefferson’s silence in response to the published reports. when harriet enters his “sanctum sanctorum” without his permission in order to examine her “passing” wardrobe, she is discovered by jefferson, who urges her to ignore the evidence: he was asking me not to leave. he was asking me to forget that my mama was sewing a wardrobe for my departure. . . . and he was asking me to bide by his rule, which dismissed, by silence, anything unpleasant in the household. he wanted me to pretend my mother’s efforts never took place. the way he responded over the years, with silence and pretense, to the savage rumors in the press about himself and sally hemings. ( ) one month following this unplanned meeting, harriet approaches jefferson as he gazes out from the portico of the entrance hall of the main house. since they last spoke, harriet was assaulted by charles bankhead, husband of jefferson’s granddaughter, anne randolph, and took to her sickbed for a number of days. in this encounter, jef- ferson shows some concern for harriet but feigns ignorance of the drunken attack that occurred under his roof: “he cannot bring himself to speak of it, i thought, so he is acting like he acted years ago when they accused him, in the press, of taking my mother for a mistress. he never spoke of it. and his accusers went away” ( ). again, rinaldi is appropriately accurate: jefferson made no public comment in response to callender; evidence exists of bankhead’s brutality. furthermore, harriet’s awareness of the pretense that jefferson maintains and that her mother colludes with creates additional internal tension in an au- thentic way as she moves towards her decision to start a new life away from the only home she has ever known. bankhead’s assault on harriet should be labeled partially accurate: no historical evidence corroborates the specific episode in rinaldi’s novel. but historical evidence supports the possibility that such an event may have occurred. rinaldi adapts the historical evidence pro- vided by brodie: one night burwell prevented the drunken bankhead from obtaining more brandy, shouting erupted, and thomas mann randolph arrived and knocked bankhead to the floor (brodie ). no historian identifies harriet as the object of an attack. the novel situates harriet alone initially when confronting bankhead, and his violent actions against her thwarted first by thruston (a gardener, a filling in gaps in the historical record character not in the historical record), followed by the arrival of burwell and randolph. perhaps rinaldi also relied upon the scholar dumas malone who claimed that jefferson freed harriet to protect her virtue at monticello. gordon-reed, who never comments on rinaldi’s work, dismisses malone’s claim: “there is no record of a precipitating event— a rape or attempted rape of harriet hemings, for example—that might have increased the sense of urgency to have her leave monticello. there is no indication that there was a persistent but unwanted suitor with whom harriet had to contend” (thomas jefferson and sally hemings ). rinaldi authentically depicts harriet awakening to a profound comprehension of her vulnerability. the belatedness of her compre- hension—harriet is nineteen at this point—reminds readers of her sheltered status. this scene certainly increases “the sense of urgency” that compels harriet to accept the advice to leave, and thus propels the plot. rinaldi also strikes a culturally authentic note, however unintentional this may be: if harriet risks a sexual assault within the main house, how much more vulnerable must be the slave women at monticello—or on other plantations—who are never privileged enough to enter the master’s house? harriet does not ponder whether other female slaves at monticello or neighboring plantations would consider her assault an exceptional occurrence or a regular threat they are forced to live with, and it would be inauthentic for her to inquire about such acts typically conducted in secret, considering how sheltered she has been. rinaldi deserves some credit for providing at least a partial view of this serious issue. conflicting influences: thomas mann randolph and martha randolph again, before examining the four historical inaccuracies, the accuracy and authenticity in the characterizations of jefferson’s daughter martha randolph and her husband thomas mann randolph must be consid- ered, especially in regard to what their characterizations reveal about harriet and jefferson. the depiction of this married couple, who never appear together in the novel, adheres to the historical records known about them. while thomas mann randolph’s generosity and martha randolph’s bitterness may both be exaggerated to serve rinaldi’s plot strategy, their depictions do not violate the criteria for accuracy. rinaldi sets up harriet to transform over the two and a half year period her narrative covers, to develop a complex, thoughtful recognition of her immediate life choices. both randolphs provoke her transformation. brian dillon in particular, thomas mann randolph is presented as a countervoice to jefferson in his empathetic encouragement of harriet. jefferson’s son-in-law makes a number of crucial appearances in harriet’s final years at monticello. rinaldi depicts martha and their children residing at monticello (having moved there years before the narrative begins), while he visits occasionally, and in the years during which harriet keeps her journal he serves as governor of virginia. rinaldi’s favorable depic- tion of him is the most radical departure from the conventional views of any particular historical individual featured in this novel. the first time harriet mentions him, she attributes his alleged loneli- ness to being married to martha, and she asserts that “everybody” knows “he’s crazier than a loon” ( ). gossip about randolph referred, to some degree, to his mental instability. (rinaldi even depicts randolph declaring, “i feel like the proverbial silly bird who cannot feel at ease among the swans,” a self-conscious assessment randolph did utter, in a different context, of course [ ; ellis ].) sally hemings springs to his defense: folks may label him “crazy,” but at the time of this mother- daughter dialogue in , jefferson’s son-in-law is “about to propose to the legislature that all virginia’s slaves be freed and deported,” a much bolder effort on behalf of slaves than anything jefferson attempted, sally says ( ). “thomas mann randolph, the person they all say is crazy. well, if he’s crazy, that man, then i’m the queen of france” ( ). in their first dialogue, randolph dismisses harriet’s restatement of her mother’s claim about the state’s emancipation legislation. it will not pass, he accurately affirms ( ). though blocked in his efforts to reduce the number of slaves in the state, to distinguish his politi- cal record from jefferson’s passive acquiescence to the status quo, he focuses on harriet’s potential freedom. the issue of determining authenticity necessarily becomes more elaborate when the reader must disentangle various historically based characters’ motives. sally seems intent on counteracting what she per- ceives to be her daughter’s inflated view of jefferson. sally had prepped randolph to speak to harriet about her choice to leave monticello. this implies not only sally’s elevated view of randolph, but also a concern that her own persuasive powers may be inadequate. furthermore, sally does not request that jefferson or martha randolph propose to harriet that she make plans to leave, and perhaps she has not even discussed harriet’s leaving with martha randolph. randolph speaks to harriet of jefferson creating a “velvet trap” for himself at monticello, a metaphor suggesting current comforts are a filling in gaps in the historical record temporary illusion and will be paid for eventually with painful conse- quences. he questions whether harriet would be willing to escape the trap by leaving monticello. he tells harriet that if she stays, marries, and bears children they will be slaves: “‘worse than you. by then your master will be dead. and who’s to care about whether your children are slaves or not. or if they’re sold or not.’ well, the man had me there, just like a fox caught in a leg trap” ( ). harriet reveals that previously she never considered the potential status of her children. that’s a remarkable admission for a -year-old who has lived her entire life on a slave plantation. it suggests that her mother and older brother neglected to alert her to, arguably, her most pressing personal responsibility. her lack of foresight emphasizes how contentedly she has dwelt in the present, as well as how unwilling her mother has been to discuss the choices she made when she was younger than harriet. is it authentic, “within the realm of likelihood or possibility,” to use hintz and tribunella’s criteria, that sally would not have discussed with har- riet the consequences of her sexual choices or that harriet would not have imagined them on her own? that seems doubtful. but in terms of narrative strategy, a degree of authenticity may be sacrificed in order for harriet to achieve meaningful insights that readers may presume a -year-old living as a (relatively privileged) slave would have acquired at a younger age. the next time harriet and the governor talk, one month later, a sense of urgency compels randolph to insist that harriet prepare to leave. he knows that harriet has been assaulted by his son-in-law and, unlike jefferson, openly acknowledges and even condemns bankhead’s conduct. randolph’s attitude strikes an authentic note, even if no docu- mentation exists about his direct influence on harriet. he regrets not killing bankhead after he stabbed his son, thomas jefferson randolph, and then delivers the fiercest, most graphic condemnation of slavery in the entire narrative: bankhead represents everything that is so despicable about this system we live under. and i see you as a victim, along with my anne. for the same system that nurtures slavery, nurtures and tolerates all the evil impulses in men. it tolerates their laziness. and violence. it looks the other way when they turn from their wives to the women in the quarters and produce children like you and your brothers, who are left to find their way in such confu- sion, belonging neither to the nigra nor the white community, yet being part of both. ( – ) brian dillon this is a cry of helplessness, by both a governor and a father, when confronting a cultural norm, and his empathy for harriet is evident as he creates a parallel between his own daughter and harriet. the reader must presume that harriet does not personally know any slave who could articulate such antagonism, a circumstance that contributes to the soft focus in which her narrative views slavery. randolph’s speech counteracts jefferson’s silence: it would be hypocritical, certainly not authentic to what is known of jefferson, for him to state such a condem- nation. randolph acts upon his moral concern: he will advise jefferson about harriet’s decision, negotiate for his wife, martha, to tutor harriet, and reveal in private to a white bachelor who has visited monticello and voiced his admiration to him of harriet that a betrothal to harriet would provide cover for her, and perhaps the good deed could lead to marriage, which would require that harriet pass. effectively, randolph becomes harriet’s plot director and the behind-the-scenes hero of the novel, while jefferson remains an observer. thomas mann randolph addresses harriet like a young adult who will be capable of adapting to her move away from monticello. martha randolph attempts to belittle harriet. rinaldi’s unflattering depiction of martha may prompt readers to wonder whether martha was so sour on the hemingses and so duplicitous in her treatment of harriet. she senses that her husband plotted to allow harriet to leave, and she describes his legislative proposal: all this nonsense about introducing legislation to give virginia’s slaves their freedom. freedom to do what, i ask? and how? why, all the nigra servants on this place, with the exception of your mother, have to be led by the hand to eat, or they’d starve. that’s how much sense they have. you think it’s easy out in the world? you think all you have to do is smile and curtsy and you’ll have your supper? ( ) her racist-coated assessment is challenged by the evidence of the network of slave laborers who maintained the property and produced revenue from the nailery and elsewhere (stanton – ). her intensely pessimistic outlook plays off against the realistic, even existential, out- look her husband expresses to harriet. when thomas mann randolph develops his “velvet trap” metaphor, harriet notes that jefferson is kind to her. he responds, “kind, eh? well, kindness is not freedom. and security is not freedom. freedom is often lonely. nobody takes care of you. you take care of yourself. you think for yourself. you do filling in gaps in the historical record dim-witted things, and you are sorry for them. you pay for them. but there is no feeling in the world like freedom” ( ). madison does not indicate in his memoirs how martha interacted with him or sally and harriet. cynthia kierner’s recent biography of martha implicitly challenges the harsh depiction that rinaldi offers. while kierner’s conclusions deserve to be weighed against rinaldi’s depiction, her biographical study will not lead a reader to conclude that martha’s role in wolf by the ears is historically inaccurate. at the time in which harriet writes her narrative, martha’s mother and all her siblings from her parents’ marriage have been deceased for over years. (her mother died when she was just ten.) such a circumstance allows us to understand why the father-daughter bond would be so tight. her life story, kierner asserts, “counters the rhetoric of southern patriarchy to the extent that she herself had significant authority and influence— along with myriad responsibilities and obligations—throughout her adult life,” and it can be interpreted “as a case study of what could hap- pen when patriarchy malfunctioned because men [both her father and husband] were unable or unwilling to fulfill their prescribed domestic roles,” especially in fending off debt ( ). in rinaldi’s novel, martha complains to harriet, “there are alto- gether too many hemings on this place to suit me.” she refers to herself as jefferson’s “only surviving child” ( ). nearly two years later and just a few months prior to harriet’s departure, martha tells harriet that her father is peter carr, jefferson’s nephew, a man, she claims, her father indulged: “it was no way to repay my father for his kindnesses, mixing with the servant women and producing children in so irresponsible a fashion. but then, peter carr never was responsible. i suppose that’s why my father feels obligated to help sally hemings’ children” ( ). the oral tradition supports not the claim itself, of course, but the ac- curacy of martha promoting such a claim: her eldest son, thomas jef- ferson randolph, told a nineteenth-century biographer of carr’s role and attributed his information to his own mother. martha defended her father’s reputation with the ugly tactic of smearing sally (as well as her cousin carr). even prior to the scientific findings of the dna research, martha’s claim was demolished as a convenient fiction. it seems preposterous that martha would not know of her father’s long- term intimacy with sally hemings: that would require an excessive amount of willful ignorance. she also presumes that her allegations will not be challenged: “i know your mama hasn’t told you. and she never will” ( – ). brian dillon when thomas mann randolph talks to harriet, he presumes she has been coddled at monticello, allowed to live in a safe, cocooned world where few demands are made upon her. martha randolph adopts a similar stance. but note the differences: he wants her to perceive herself as an agent of her adult years, to make choices that assert her own independence. he pushes her out for her own good. he wants harriet to recognize how confined she is at monticello; martha, in her complaining mode, wants her to see that she is privileged. martha scorns her half-sister and essentially demands she express thanks for all she has been given. and she lies to her about her parentage: can we be sure she does not believe her own lie? thomas mann randolph presumes harriet is capable of imminent maturation; martha does not. he presses harriet to change her status; she urges harriet to accept her status as a powerless individual who should be grateful for her comfortable existence. he wants harriet to adopt a new identity who wields as much freedom of choice as her gender allows in the s; she seeks to impress upon harriet her sense of alienation from both the white randolphs and the mulberry row slaves. harriet responds to the contradictory concerns this couple raises with an authentic intent to figure out who deserves her trust. based upon her own instinctual feelings and later by the corroboration her brother beverly provides from the farm book regarding the absence from monticello of peter carr at the time of the hemings children’s conception, harriet clings to her belief that jefferson is her father. she also will not relinquish her view of jefferson as a man deserving pity. why she does not will be examined in conjunction with rinaldi’s four historical inaccuracies. harriet’s in-between status and her absent brother tom harriet’s reflections on the frequent references to her absent oldest brother, tom, the first of the four historical inaccuracies, highlight the unique in-between status she occupies at monticello. this first inaccuracy deserves to be considered in light of this context. harriet moves between the mulberry row values expressed by thruston (the gardener) and mammy ursula (who tells folktales and dispenses advice regarding potions and superstitions), and the white culture’s values, expressed by jefferson, martha and thomas mann randolph, and thad sandridge. this in-between status complicates in interesting ways both harriet’s efforts to assert her own identity and a reader’s efforts to prove filling in gaps in the historical record her character achieves authenticity. weimin mo and wenju shen begin with the distinction between facts and values when discussing accuracy and authenticity yet acknowledge the conceptual vagueness with these terms. more specifically, they note that cultures “affect each other. they constantly absorb each other’s values, attitudes, and beliefs; sometimes they actively clash. therefore, cultural values are not stagnant. when an author’s version of a culture can be accommodated inside the range of values acceptable within that social group, a measure of authentic- ity has been achieved” ( ). harriet receives conflicting advice from members of both monticello communities and must determine which values to accept and which to reject. in one dialogue, jefferson, a master of indirection, suggests to har- riet that she may be romantically interested in thruston. rinaldi con- structs this dialogue that accurately depicts jefferson’s attitude towards slaves intermarrying but within the conflicted context of obligations made to sally to free her children. operating with much cunning, jefferson attempts to plant a seed that would serve his current and long-term purposes: marriage with thruston would keep harriet on his premises until he dies. their offspring would add to jefferson’s capital and help offset his debt. he would be appalled if harriet had thought he wanted her to stay due to her monetary value as a breeder of slaves (overseen, perhaps, by his daughter martha). in fact, harriet does not indicate that such a thought enters her mind, though she should be labeled realistic rather than cynical if it did. lucia stanton notes, “like other slave owners, jefferson recognized the value of family stability in the slave quarters and tried to discourage abroad [off-plantation] mar- riages” ( ). as he wrote in to one of his property’s overseers, “there is nothing i desire so much as that all the young people in the estate should intermarry with one another and stay at home. they are worth a great deal more in that case than when they have husbands and wives abroad” (qtd. in stanton ). also, potential offspring from a harriet-thruston marriage would divert attention, jefferson may be thinking, from his genetic responsibility. when harriet introduced thruston in her narrative she noted, “he is light skinned, but darker than i am. i’m practically white. and i’m tall. and i have reddish hair. and some freckles. which ought to give a body an idea of the trouble i’m in right off” ( ). thruston’s role highlights harriet’s in-between status. she scolds him for speaking “like a field darkie who didn’t know any better” ( ), a remark that acknowledges her awareness of most slaves’ illiteracy brian dillon and limitations and thruston’s choice to align himself with those at monticello incapable of advancement as long as slavery persists. at this early point in her narrative, harriet still seems content with her current status. thruston, angry because of his recognition of the limitations on his potential choices, pushes back against “miss high and mighty,” as he labels harriet in this scene: “why should i talk like white peoples? . . . ain’t never gonna get me anything. doan wanna talk like white folk, anyway. ain’t nuthin’ ‘bout them i admire” ( ). she offers no response. this exchange segues into her encounter with thomas mann randolph as she serves him breakfast. he scolds her in a manner that echoes harriet’s confrontation with thruston: “talk to me. . . . don’t give me that stupid darkie routine” ( ). randolph’s effort to draw harriet out provokes her identity confusion, disrupts her contentment. and who is to blame for her extraordinary reticence with monticello’s white residents? who has sheltered her? though tutored academically ( ), harriet moves in a twilight world, immersed neither in the slave community nor the white world of jefferson’s extended family. later, thruston concedes that he wants to marry harriet but that she should seek her freedom. harriet fears the unpredictability of her life if she leaves monticello and enters a white community yet knows that she does not want to marry thruston. the perspective that harriet takes of the mulberry row slaves is dis- torted by her lack of regular contact with those who live there as well as her love for jefferson and pitying attitude towards him. while this perspective fails to conform to the historical record, to achieve accuracy, it does achieve authenticity considering the limitations that stem from harriet’s in-between status and defines her identity. in a later episode, harriet silently criticizes the limited goals of two girls from mulberry row who are nearly her age—her peers and yet not her peers—who flirt with the well-muscled field hand jupiter: “how stupid! where would it all lead? where would it get them? one of them will marry jupiter and have baby after baby down in the slave cabins” ( ). one of harriet’s internal conflicts centers on her recognition that her opportunities far exceed the mulberry row residents’: neither these two young women nor jupiter would be keeping a journal or tutored in french. harriet is tutored by mr. oglesby, and once her plans for leaving begin to form, by martha, with a curriculum that jefferson oversees (which includes limits on reading fiction [ ]). again, though, as sally’s child, har- riet proves to be an exception: “unlike many slaveholders, jefferson did not try to prevent his slaves from learning to read (although there filling in gaps in the historical record is evidence he frowned on the second stage of the learning process, writing), but he apparently took no active part in providing them with an education” (stanton ). yet the white community’s values have up until recently been considered out of her reach. in their dialogue that takes place days after harriet has been as- saulted by bankhead, after jefferson succeeds in proving to himself that harriet is discreet (she does not burst out crying or accuse jefferson of failing to control his own in-law and guest), he raises the issue of her leaving monticello. as evident in all five of his dialogues with harriet, as well as the one heated exchange she overhears between jefferson and beverly regarding her older brother’s desire to attend the newly formed university of virginia, jefferson exhibits contrary sensibilities: self-absorbed and emotionally guarded, yet intent on establishing a meaningful personal link. he admits that the influence of sally and thomas mann randolph prompted his willingness to allow harriet to leave: so, then, it is best that you go. i realize i was unfair to you at our last meeting, harriet. i tried to impose my will upon you for my own selfish reasons. yes, of course, i want you to stay, as i want beverly to stay and as i wanted tom to stay. but i must be a realist. there is nothing for you here. you are young and of a fine countenance and well bred. you must take your place in the world. ( ) presumably, jefferson trusts that she will understand that his “own selfish reasons” refers to a degree of emotional neediness, however incapable he may be of overtly expressing such needs to her. the reference to tom challenges the historical record. rinaldi tries to have it both ways: in the family tree listed at the front of the book under the name thomas hemings it says, “(possibly).” rinaldi seems to fashion “tom hemings” out of speculations in brodie’s biography, which acknowledged that references in jefferson’s farm book to vari- ous individuals named tom proved confusing rather than conclusive ( – n ). yet as the absent oldest sibling of harriet who left monti- cello when harriet was ten and passed as white, he is referred to in wolf by the ears as a real individual, not only by jefferson and harriet, but also mammy ursula and other slaves quartered on mulberry row, sally, and thomas mann randolph. madison’s memoir names only beverly, harriet, and eston as his siblings. callender reports gossip about a son named tom, but no credible historian confirms his existence. the brian dillon novel’s references to absent tom do not undermine in any genuine way the authenticity of harriet’s internal conflict. they are gratuitous. the manner of his leaving serves as a counterexample to jefferson’s wishes for harriet’s departure: “when you go, harriet, i would like it to be done right. no running off into the night like tom. promise me you will not run off” ( ). harriet will dutifully accept this advice. alert readers should recognize that such an example is unnecessary for rinaldi’s narrative purpose: harriet’s efforts to please jefferson are on display in every one of their scenes together. jefferson’s wistful recol- lections about tom do conjure a sentimental view of the slave-holding ex-president, though, that the historical record fails to support, and thus this first of the novel’s four inaccuracies deserves our attention. negative stereotypes of slaves are promoted by characters whom the reader is discouraged from agreeing with (such as martha randolph), and harriet confronts in a meaningful way her in-between status as neither wholly slave nor wholly free. yet at times the sidelong view of slavery that harriet provides from her comparatively privileged position as a house slave veils the documented evidence of the daily working conditions and inferior accommodations for the slaves of monticello, thereby sentimentalizing their existence. in an early entry in her journal, she gushes: “i love him, i know i do. and to show how much, i write down here and now another truth. the nigra servants on this place are well treated. and well clothed and fed. mama says the master, like his father, peter jefferson, has never used a whip on one of his servants. and no one goes cold or hungry” ( – ). though harriet does work occasionally in the weaver’s cottage on mulberry row, she avoids the nailery or the fields where many of the monticello slaves were employed and subject to punishments. stanton asserts that whipping of slaves at monticello occurred at “levels well below those of many of his neighbors. the whip was, however, by no means eliminated. from the s jefferson employed on the monticello plantation over twenty overseers with diverse temperaments and management styles. some were cruel, even by the standards of the day” ( ). such cruelties are removed from harriet’s line of vision. rinaldi’s choice of narrator— a domestic servant granted privileges unavailable to the other slaves jefferson owns—significantly softens what may very well be the high school reader’s first literary introduction to slavery in the south in the early s. the division in jefferson’s mind between the hemings children and the mulberry row slaves lurks behind his admission that “there filling in gaps in the historical record is nothing for you here.” no one disputes that sally’s children were relatively privileged, never sent to work in the fields or in the nailery, for example. his praise of her “fine countenance” and breeding, weirdly ironic because he does not acknowledge his role in her breeding, con- flicts with his previously published arguments of african americans’ racial inferiority. query xiv from notes on the state of virginia is often cited as an early expression (written in – ). in a question and answer format, jefferson ponders why emancipation of the slaves within the state will not occur: why not retain and incorporate the blacks into the state, and thus save the expence of supplying, by importation of white settlers, the vacancies they will leave? deep rooted prejudices entertained by the whites; ten thousand recollections, by the blacks, of the injuries they have sustained; new provocations; the real distinc- tions which nature has made; and many other circumstances, will divide us into parties, and produce convulsions which will probably never end but in the exterminations of the one or the other race. ( – ) jefferson then labels skin color in the category of “physical and moral” objections: “is it not the foundation of a greater or less share of beauty in the two races? . . . they are more ardent after their female: but love seems with them to be more an eager desire, than a tender delicate mixture of sentiment and sensation. their griefs are transient” ( ). he compares african americans unfavorably with native americans: “never yet could i find that a black had uttered a thought above the level of plain narration” ( ). such remarks, though written decades before harriet’s birth, provide some context for understanding his praise of her. rinaldi’s novel implies, at least, he was capable of making an exception to his theory in regard to both his sentimental worries about absent tom and his view of harriet: this may be pure fantasy on the novelist’s part. rinaldi’s depiction defies what we do know of jefferson’s attitude toward slavery in his post-presidential years. to note one example, in a letter from , jefferson tried to discourage a wealthy neighbor, edward coles, from carrying out his plan to move his slaves to illinois, where coles intended to free them and give them land: while jefferson recognizes that “the hour of emancipation is advancing,” he advocates that slave owners like coles “reconcile yourself to your country and its unfortunate condition,” and that while such proposals are worthy of brian dillon discussion, the time is not right to enact them. in this same letter he also asserts a point that directly echoes his sentiments regarding the inferiority of african americans from his notes: “their amalgamation with the other color produces a degradation to which no lover of his country, no lover of excellence in the human character can innocently consent” (letter to edward coles ). andrew burstein comments, “jefferson’s pseudoscience rightly diminishes him in the eyes of history for one inescapable reason: he did not grow over time” ( ). rin- aldi’s depiction of jefferson in this scene with harriet conflicts with the language of this letter. she also ignored brodie’s analysis of this letter, in particular the quoted sentence regarding “amalgamation” (misce- genation). brodie states that jefferson’s “octoroon children had been subjected by virginia society to the same degradation as the blackest african, and he had been pilloried for siring them. amalgamation for jefferson truly did not raise the black; it only degraded the white” ( ). of course, it is highly unlikely that ya readers would find any in- consistency here: harriet indicates no awareness of jefferson’s notes. presumably, she would not intend to please him if she was aware of his pseudoscientific racial theory, and knowledge of his theory would undermine her sentimental response to slavery. therefore, while it is plausible that harriet knows nothing of this publication from nearly years earlier or his current thoughts as expressed in his correspon- dence, this literary criteria of authenticity is earned at the sacrifice of exposing jefferson’s hypocrisy. his command that harriet must take her “place in the world” sounds sententious, even paternalistic, and the irony, of course, is that taking her place requires disguising her identity. he wields language with impressive authority, yet so many of his statements open up rabbit holes down which he refuses to go. harriet’s intense admiration for jefferson blocks her from challenging as suspect any of his stated intentions for her. this contributes to her portrait of jefferson as a figure deserving pity. jefferson’s confusing claims about george wythe and his self-promoting recollections about the declaration harriet’s inability at crucial points in her narrative to decipher when jefferson speaks in deceptive ways to manipulate her and others may very well be authentic: she does admit how sheltered her life has been. this inability is most evident in the extended scene that highlights beverly’s creative intellect and his frustration with jefferson, a scene filling in gaps in the historical record in which the novel’s second and third historical inaccuracies emerge. working from written accounts of the previous generation’s fascination with the pioneering work of hot air balloons, beverly has constructed one of his own, fueled not by straw or sticks but a burning claret-soaked sponge. he intends to impress jefferson in an effort to convince him that he should be allowed to enroll at the newly established university of virginia. beverly and jefferson confer about this on a hilltop near mulberry row. hiding behind a washhouse, harriet listens in to their exchange. though this narrative strategy of overhearing crucial infor- mation may be somewhat clumsy, the scene effectively pits a defensive jefferson against a frustrated beverly. jefferson acknowledges that beverly’s intellect warrants his admis- sion to a university program, but he lacks the power to institute such race mixing even on a campus he founded. jefferson argues by anal- ogy: he summarizes the case of the white man who murdered george wythe and a young man living with wythe, michael brown. in addition to being jefferson’s most influential teacher at the college of william and mary, wythe also served in the continental congress, and remained a lifelong friend. jefferson explains to beverly that wythe, twice widowed, developed a relationship with his mulatto housekeeper, lydia broadnax, and that she bore him a son (michael brown), whom wythe educated. in his will, wythe left the housekeeper his home and other property, and for brown half of his bank account. the other half was left to his white grandnephew who poisoned wythe, broadnax, and brown in an effort to inherit it all. the will (written while jefferson was president) entrusted jefferson to be in charge of brown. rinaldi apparently relies upon brodie to create this scene. the his- torical evidence does not support the claim that wythe and broadnax produced a son, nor that wythe was intimate with broadnax, whom wythe had freed and who continued to care for him as a paid servant. brodie states, “jefferson must have surmised, with many others in vir- ginia once the details of the will were circulated, that lydia broadnax was almost certainly wythe’s concubine and michael brown his son. that the president believed that wythe had waited in writing his will till he was certain he could count on jefferson’s support for his son seems likely” ( ). in rinaldi’s scene, jefferson speaks in a lawyerly manner to beverly regarding the exact nature of the relationship: “it was common knowledge that the boy was wythe’s illegitimate son” by his mulatto housekeeper, lydia broadnax ( ). bruce chadwick challenges this claim: the “copious population records . . . kept at the brian dillon time” never listed broadnax as a mother; “wythe had a long history of tutoring both black and white teenagers, and michael was just one more” ( n ). philip morgan notes: “of the fourteen witnesses who testified to wythe’s poisoning, not one mentioned that lydia broad- nax was his mistress or that michael brown was his son. no newspaper reported any such gossip” ( ). rinaldi blends some historically accurate claims with brodie’s specu- lations in this scene. broadnax, jefferson explains to beverly, survived: but because, under virginia law, no nigra can testify against a white, [this grandnephew] was acquitted. leading men in richmond rushed to defend him. the indictment against him was quashed without a trial. and a murderer was allowed to go free because my dear friend and mentor, a signer of the declara- tion of independence, did not try to hide the fact that he had a mulatto mistress and could not disown his son. now do you understand? ( ) the implication is that fourteen years later, the political culture in vir- ginia has not progressed, and jefferson is powerless to provoke change. jefferson’s support for beverly will not extend beyond monticello: he will neither help nor hinder him in the outside world. jefferson may fear that beverly’s presence at the university will expose beverly’s ances- try and provoke newspaper writers to resurrect stories of his intimacy with sally hemings. he will not allow any attention to be drawn to his role as the father of a mixed-race child, as he may have felt such atten- tion affected wythe’s posthumous reputation. while rinaldi is correct in depicting jefferson as asserting that state laws prohibited testimony from a black person against a white person, it bears noting that wythe and jefferson had formally approved this law when they reviewed the state statutes decades earlier (chadwick – ). jefferson’s pleading insistence that he cannot push against the weight of virginia’s white supremacist conventions contributes to the novel’s pattern of viewing him with pity, as a man with a steady moral compass whose willingness to guide others in the right direction is ignored. when rinaldi’s dra- matic dialogue—which embeds both this second inaccuracy regarding wythe and the third, to be considered below—is set against the histori- cal record, the reader’s pity may dissolve. jefferson’s effort to convince beverly of his powerlessness leads him to refer to his early draft of the declaration, the novel’s third historical inaccuracy, which he claimed called for the abolition of slavery: “but filling in gaps in the historical record there were those who would have seceded from the yet unformed union if my phrases about doing away with slavery were not struck from the document” ( ). jefferson’s claim accurately reflects his excised por- tions of his draft of the historic document, in which he blamed “the christian king of great britain” for the “horrors of the slave trade.” but jefferson only favored banning the importation of more slaves from africa, not the ownership of slaves, and in , he owned about slaves (mccullough ). he did write the astonishing phrase “all men are created equal,” but his own life proved he did not accept this either literally or legally. seeking from beverly understanding and forgiveness for his passivity, jefferson disingenuously simplifies the argument he crafted years earlier, and thus his remarks constitute a historical inaccuracy. yet his posture as a morally astute statesman powerless to affect change is authentic regarding the consistency in jefferson’s thinking about slavery from his early years in politics to his retirement at monticello. it is impossible to determine whether rinaldi knows that jefferson veers sideways from honesty here or that she presumes her reader will view jefferson with suspicion. ellis peels away jefferson’s layers of obfuscation to uncover his support of the south’s status quo: jefferson knew . . . that many established slaveowners in the tidewater region favored an end of imports because their own plantations were already well stocked and new arrivals only re- duced the value of their own slave populations. ending the trade in virginia, in short, was not at all synonymous with ending slavery. with regard to slavery itself, jefferson’s formulation made great polemic sense but historical and intellectual nonsense. it absolved slaveowners like himself from any responsibility of complicity in the establishment of an institution that was clearly at odds with the values on which the newly independent america was based. ( ) in rinaldi’s account, jefferson trusts that beverly lacks the knowledge to challenge him. in reporting this dialogue, harriet lacks the knowledge to treat jefferson’s claim with any skepticism. but a reader informed about the composition of the declaration and alert to jefferson’s in- tentions should challenge his self-serving and dishonest appeals in this exchange with beverly. near the end of his second term as president (in ), a ban was issued against the further importation of africans to serve as slaves. as historian alan taylor writes, “but the new law manifested no brian dillon commitment to antislavery within the nation and no bar to the booming interstate trade in slaves. indeed, by eliminating foreign competition, virginians could sell more slaves to the lower south. the sellers also expected to sleep more securely as the domestic slave trade diffused their surplus slaves at higher prices to the south and west. by banning the import slave trade while expanding the interstate slave trade, the virginians hoped to render slavery safer and more profitable” ( ). from his composition of the notes to the end of his second presidential term and all the way to his retirement at monticello, jefferson remained consistent in regard to slavery. open-ended closure in the novel and the historical record rinaldi’s choice of closure must be set against the historical record before proceeding to the novel’s fourth historical inaccuracy regard- ing the missouri compromise. beverly is not won over by jefferson; he refuses to commiserate with jefferson’s excuse-making. in his final dialogue with harriet, late at night, with beverly on horseback set to run away from monticello, he claims he does not know where he will go. (gordon-reed notes, “there is no record of an event that led to [beverly’s] departure” [thomas jefferson and sally hemings ].) he shares his breakthrough insight gleaned from the pages of jefferson’s farm book: “i check it every chance i get. . . . to see. how he marks us down. . . . on bread lists. on blanket lists. we’re on those lists, you and me. and mad and eston. with all his other slaves” ( – ). while harriet will soon leave in a state of sentimental ambivalence, beverly leaves full of righteous anger. “when he dies, people will see those lists. they’ll see we were slaves. a hundred years from now that’s all people will see of us, all they’ll know” ( ). rinaldi’s novel responds to beverly’s despair by animating the lives of what could have remained only names in the farm book. the novel comes full circle, from har- riet’s concern regarding whether jefferson will discuss her mother in his autobiography to beverly’s evidence that their mother and her children exist on paper only as budget items. the farm book establishes that beverly left monticello either in or and harriet in (brodie – ). rinaldi closes her story after harriet details her first night away from monticello. gordon-reed speculates that beverly may have eased harriet’s transition to wash- ington’s white culture (thomas jefferson and sally hemings ). rinaldi presents harriet’s departure as the ultimate leave-taking of her family: filling in gaps in the historical record both she and beverly presumed their parting was final, and there is no suggestion of a reunion at some unspecified time. the reader travels with harriet only miles from monticello to the first stop on her way to washington. this is the only break in the narrative from the spatial limitations of monticello. a white chambermaid and her daughter tend to her in her room above a tavern. though on this first night there is no challenge to her passing, her inadequate preparation for entering the world outside monticello, her lifetime of being sheltered, is evident in her response to the chambermaid: “it came to me, watching the woman, that she was of a poorer class than i had known any white woman to be. . . . i never considered that there were white folk in the world worse off than i” ( – ). working from madison’s memoir and the profun- dity of silence required by beverly and harriet who chose to abandon their black past and their bond with the third president, gordon-reed asserts that beverly and harriet “left monticello as white people, with no learning curve for how to present themselves as caucasians. they married white people who may not have known they were of african origin or had ever been enslaved” (the hemingses of monticello ). of course, if gordon-reed’s speculation were true, then harriet did not marry someone like thad sandridge, and her life did not follow the direction in which her narrative seemed to be headed. yet rinaldi’s open-ended conclusion certainly sounds authentic. lacking historical evidence that harriet’s older brother facilitated her move, rinaldi creates this scenario: thomas mann randolph plots a meeting between harriet and thad sandridge, a harvard-educated northerner, an architect appalled by slavery and physically attracted to harriet. somewhat late in her narrative, harriet reminds her reader that though she fended off thruston’s appeals and suffered from a thwarted violent attack by a sexual predator, her romantic experiences are limited and make her vulnerable. upon first meeting thad she decides she’s in love with him ( ). he demonstrates restraint and indicates his awareness of their power differential: “i’ll force you into no decision concerning me. i have the advantage of having known you for some time now. you do not know me. i would have you taste free- dom first. with no conditions attached to it. i do not wish to be a new master. i wish to be your friend” ( ). the romance plot is implied yet deferred. thad, calmer in his ardors, indicates he favors a leisurely pace to whatever mutual feelings may develop. harriet’s admission that she thinks she has fallen in love at first sight indicates she could benefit by restraining her emotions. he asks harriet to call him by his first name brian dillon and just once to call her master “mister jefferson.” harriet acts upon this advice. the novel closes with harriet’s description of jefferson’s response to the only time she referred to him this way: “his gaze held mine for a moment and there, in those blue depths, i saw the shock and confusion, yes, even the hurt. his head went back a little, with my words, as if i had struck him” ( ), and then he shed tears. success for harriet is achieved by evoking from jefferson a genuine emotional response to her departure, though readers should question how long she will feel satisfaction over such a slight victory. rinaldi gives this scene prominence of place. but alert readers may presume that while such an ending makes sense structurally, harriet’s overbearing emphasis on a tear (“tears! for me!” [ ]) may indicate only that her movement into adulthood has barely begun. harriet’s parting words to jefferson indicate her eagerness to take directions from thad. drop- ping the title “master” in favor of “mister jefferson” seems to serve as a transgression that only thad, harriet, and jefferson will know. it marks a shift away from subservience, but harriet’s intentions are not thought through. does she imply that if he must persist in remaining silent about her paternity she will address him as no more than her landlord? if so, his tear signifies his emotional pain. or is it her way of indicating she will play along with his desire for history to be uninformed of his double life, that she implies she will maintain their secret? if so, then his tear signifies his satisfaction that harriet has acquired, in his misted eyes, an adult-like acceptance of southern social conventions. werner sollors’ neither black nor white yet both identifies concerns specific to the issue of closure in fiction like wolf by the ears: “it is not surprising that interracial literature has displayed a good amount of self-consciousness and some ambivalence about where and how the plot lines could be brought to a conclusion” ( ). sollors distinguishes “two recurring patterns of closure”: the one that rinaldi’s novel follows is “the wish for ‘a world elsewhere,’ whether or not it is realized,” with harriet changing her name, securing a place to live and employment, with thad’s help, and the likelihood of “a happy interracial marriage” (sollors ). (sollors does not discuss wolf by the ears.) rinaldi deserves credit for undermining the potential for readers to view the ending as absolutely optimistic. both thomas mann randolph and martha randolph attempt to check her glowing assumption of what “freedom” might consist of. she is reminded (accurately, by sally) of the cautionary tale of her mother’s brother james: trained as a chef in france while living there with jefferson, he was given his freedom by jefferson, and filling in gaps in the historical record within a few years took his own life (rinaldi ; gordon-reed, the hemingses of monticello – ). harriet moves from a protected estate where she was familiar with everyone she encountered to an urban area where she knows only one man (and with a knowledge colored by unfamiliar intense emotions). she moves from a site where her identity both protected her and provoked uncertainty for her to a site where she will assume a false identity. in her introduction to paradoxes of au- thenticity, julia straub defines the term in a way that applies especially to rinaldi’s chosen closure, as well as the alternative closure this essay proposes: “authenticity is not a key to happiness, a state of mind pow- erful enough to iron out the ruptures in identity and life experience that afflict modern individuals. it can also denote conflict and needs to be seen as a term of crisis” ( ). the anxiety harriet expresses over leaving her family and the only home she has ever known for good certainly constitutes a “rupture” and a “crisis.” beverly rebukes her for choosing to pass: “what’s festering inside me is that my only sister is passing into the white world and turning her back on her people” ( ). harriet’s response reveals how genuinely guilt ridden her decision makes her: “there’s days i know i’m nigra, and what’s mine is in those cabins down there. days when i know it so much that i hate myself for wanting to leave, let alone pass!” ( ) families divided between those who did and did not pass: harriet’s anxieties anticipate this new reality. whites who abide by the legal and ethical code that stipulates that harriet’s one-eighth bloodline defines her and denies her the freedom entitled to whites would perceive har- riet’s action as a form of deception. beverly’s argument is that she is being dishonest towards the one-eighth blackness that should define her identity. implicitly, beverly argues that the martha randolphs of the culture should determine how and where harriet should live. he presumes that harriet will enter a privileged status and that by doing so she somehow harms those (such as the mulberry row residents) whose status is oppressed. but as this essay has demonstrated, harriet has never been totally absorbed by either the black or white culture at monticello. she is uncomfortable in the presence of whites, as her early remarks about serving thomas mann randolph indicate. she is perturbed that thruston insists on “talking like a field darkie who didn’t know any better” ( ), and she both respects and remains skeptical about the folk stories and spells that mammy ursula taught her. she moves uneasily between two worlds, belonging in neither. if we under- stand the ambivalence involved in harriet’s choice, her decision to pass brian dillon highlights a dimension that kathleen pfeiffer finds in other works of interracial literature: it “offers a problematic but potentially legitimate expression of american individualism, one that resists segregation’s one-drop logic and thereby undermines american’s consciously con- structed ideology of racial difference” ( ). in her final conversation with her mother, harriet is told that bev- erly passed. this complicates the reader’s efforts to understand har- riet’s often angry older brother. the historical record about beverly is as insubstantial as it is about harriet. consequently, the reader is on unstable ground when judging the accuracy of rinaldi’s closure. rinaldi’s decision to depict beverly as critical of harriet’s decision to pass serves a meaningful purpose in her psychological development: she reaches her decision through intense internal struggle, without her older brother’s full support. readers who move from rinaldi’s conclusion to madison’s memoir learn that beverly and harriet did pass, though madison provides no indication that his two older siblings ever contacted one another again or if he ever saw them again after they left monticello when he was a teenager. madison’s statements about harriet create a lacuna that rinaldi fleshes out in an authentic way with thad sandridge’s role: “harriet married a white man in good standing in washington city, whose name i could give, but will not, for prudential reasons” (qtd. in gordon-reed, thomas jefferson and sally hemings ). madison’s reminiscences indicate his knowledge of harriet’s life post-monticello is limited, that the color barrier he chose not to cross separated him from harriet (and beverly) for over half a century. she raised a family of children, and so far as i know they were never suspected of being tainted with african blood in the com- munity where she lived or lives. i have not heard from her for ten years, and do not know whether she is dead or alive. she thought it to her interest, on going to washington, to assume the role of a white woman, and by her dress and conduct as such i am not aware that her identity as harriet hemings of monticello has ever been discovered. (qtd. in gordon-reed, thomas jefferson and sally hemings ) gordon-reed parses the tone of this account, detecting madison’s anger towards harriet, his assumption that she was selfish, either in passing or in failing to maintain communication with her siblings, or both. the reference to harriet’s children not being “tainted with african filling in gaps in the historical record blood” may be madison’s sarcasm and resentment toward her decision to pass (thomas jefferson and sally hemings ). rinaldi again remains true to the testimony madison provides in the one scene harriet shares with her younger brothers as they discuss her leaving. harriet’s state- ments express a sweetness that she knows to be superficial: “‘because of who we are, no matter where we go, we’ll always be together in our hearts.’ . . . they agreed with me, but i knew in my bones they were saying it just to make me happy. and i became more desolate than ever” ( – ). madison then forecasts—accurately, according to the historical madison’s memoir—that he will stay with their mother after they leave monticello. the “world elsewhere” that harriet chooses to enter provokes nightmares for her as she anticipates her new life ( ); readers may admire her bold spirit in making her move and passing despite her legitimate fears. thruston’s role typifies rinaldi’s ability to dramatize crucial features the historical record substantiates. he refers accurately to jefferson’s debts that may be relieved to some degree by selling his slaves. in a dialogue with harriet, thruston accurately forecasts that jefferson’s slaves risk being sold off and separated upon his death: he is alert to jefferson’s significant financial debts and his old age, which compounds the urgency of his cautionary advice. jefferson already sold sally’s sister thenia to james monroe decades earlier and, thruston asserts, all of the rest of his slaves are at risk: “mister bacon [edmund bacon, jef- ferson’s overseer] says the place’d be sold to pay the master’s debts. a bidder will come. . . . put us on the block. for sale. ‘what’ll i get for this fine nigra gal? she has quality.’ they’ll sell us all. and a white man would pay a good price for a piece of property like you” ( , ). while thruston intended his speculative scene to terrify harriet into fleeing monticello, to step into her freedom as soon as possible, he exagger- ated the threat to her personally. harriet and her older brother beverly were allowed to leave when they were twenty-one. five of jefferson’s slaves, including harriet’s two younger brothers, were not sold: his will stipulated they be granted their freedom (stanton n). jon kukla’s mr. jefferson’s women contrasts the treatment following upon jefferson’s death accorded to some members of the hemings family with the more than other slaves who called monticello home: “with his daughter’s help, jefferson finally rescued sally hemings and all their surviving children from slavery. against some formidable obstacles—through thoughtful actions that implied respect, gratitude, and some measure of affection—their story ended in a way that suggests that promises had been made and were kept” ( ). brian dillon the residents of mulberry row, like thruston, that is, the field hands, the nailmakers, the “superannuated” women (to use jeffer- son’s term from his farm book, which he applied to those slaves who could mind the children; harriet puzzles over this term that implies jefferson’s view of the material value of certain slaves [ ]), and oth- ers whom we may presume never entered the main house where the hemings children were welcomed, were sold in january . families were divided. thomas jefferson randolph, the president’s grandson, served as executor: he “compared the wretched scene of the dispersal sale at monticello to ‘a captured village in ancient times when all were sold as slaves’” (kukla ). though harriet’s narrative—rinaldi’s novel—ends with her departure from monticello in , the reader may imagine the sale four and a half years later of thruston, jupiter, both girls whom harriet observed flirting with jupiter, and any of their offspring. but a reader must be aware of the historical record, must have knowledge that exceeds what harriet comprehends, in order to claim her sentimental view of slavery is counteracted by the grim reality of monticello slaves on the auction block that the novel merely anticipates but does not depict. sollors acknowledges “the structural ambivalence in plot lines that are brought to forced closure at a price: each resolution rests on the denial of another possibility that is being eliminated by the choice made” ( ). rinaldi chose not to close with a more definitive tragic ending: for example, she could have added an epilogue in which har- riet returns, perhaps under some form of disguise, on the january day in when the slaves at monticello were put on the auction block. she could observe the “superannuated” mammy ursula, thruston, and others purchased by new owners: their lack of choice over their futures combined with harriet’s impotence at the sale would close the story on a deeply tragic—and authentic—note. harriet’s qualified achievement of independence would be viewed in its rightful context against the lack of any choice for her former fellow slaves. such an ending would be accurate to the historical circumstances and reinforce the rupture in harriet’s choice to leave. rinaldi’s allusion to the missouri compromise and the personal consequences of jefferson’s grim foresight in one exchange between harriet and her mother, sally discusses jefferson’s despair following upon the debates in congress over the filling in gaps in the historical record missouri compromise in : this sets up the novel’s fourth historical inaccuracy. jefferson senses that the national union achieved by allow- ing slavery to be maintained (as discussed above on his writing of the declaration) will eventually collapse. sally explains: “he fears for the union. . . . he talks about an imaginary line they are drawing across the country, with certain states slave and others free. he says a hideous evil is dividing america. he says the line will never be erased. some southern states threatened to leave the union if missouri wasn’t admit- ted as a slave state. he says it fills him with terror” ( ). rinaldi allows sally to speak lines that echo jefferson’s letter to senator-elect (of the new state of maine) john holmes: “this momentous question, like a fire bell in the night, awakened and filled me with terror. i consid- ered it at once as the knell of the union” (letter ). terror is the appropriate anticipatory emotion for the civil war, “which destroyed slavery, the political primacy of the south and the doctrine that the states were sovereign agents in the federal compact” (ellis ). but what sally does not explain, and what harriet does not know, is that jefferson feared restrictions imposed by northerners on southerners’ expansion of slavery. he favored the interstate sale of slaves, without any restrictions from the north, and he feared the potential for a slave revolt in virginia (taylor ). “the diffusion over a greater surface would make [slaves] individually happier, and proportionally facilitate the accomplishment of their emancipation, by dividing the burthen on a greater number of coadjutors,” his letter to holmes stated ( ). sally’s account, as in the three previous examples of historic inaccura- cies in this novel (in regard to tom hemings, george wythe, and the composition of the declaration), allows the reader to pity jefferson for his moral stand while powerless to affect change. on a more personal level, the civil war prompted jefferson’s grandsons to fight against one another. martha’s son george wythe randolph, who plays a silent, cameo role as a three-year-old sitting on his mother’s lap while she interrogates harriet ( ), served in the military for the confederacy, including a stint as jefferson davis’ secre- tary of war (crawford ). two of eston hemings’ sons served in the union army, beverly jefferson and john wayles jefferson, who rose to the rank of colonel in the wisconsin infantry (stanton – ). two of madison hemings’ sons crossed the color line and served in white units in ohio regiments. “they would have known that had they joined one of the available ohio black regiments, they would have been denied equal pay and equal access to advancement. . . . the hemings brothers brian dillon had identified themselves as ‘colored’ in their prewar lives. thus every day spent with a thousand white soldiers must have been full of tension as well as the dread of discovery and its disagreeable consequences” (stanton ). in his memoirs, madison reports that his son thomas eston hemings died in the notorious andersonville prison. we do not know what any of the hemings grandchildren thought of jefferson. however arrogant it may seem to assess moral responsi- bility from a position of roughly two hundred years, an examination of jefferson’s role in the maintenance of slavery and the personal and national consequences of his actions—and inactions—undermines any naive sense of patriotic pride in the decisions of the declaration author and third president. while harriet’s view of jefferson as deserving pity is authentic, considering her lack of knowledge of his various writings and his proximity to her, it is not a response that jefferson deserves. by exploring the hemings family’s life while at monticello, with rinaldi’s novel as a springboard, as well as the years after jefferson’s death, a more richly informed response to the consequences of slavery, histori- cally and for one young woman, will result. notes i thank amanda cockrell and the children’s literature anonymous readers for their patience and meaningful insights on drafts of this essay. newell bringhurst’s “a popular but controversial biography” provides a useful overview of the response to brodie’s book. see . six years before brodie’s biography, winthrop jordan noted that jefferson’s farm book indicated he was present at monticello nine months prior to the birth of each of sally hemings’s children, though overall he was absent from monticello for nearly two-thirds of the period when sally hemings conceived. jordan acknowledges that the evidence available to him prevents any claims of certainty regarding the extent of jefferson’s relationship with sally hemings. “the question of jefferson’s miscegenation,” jordan asserts, “is of limited interest and useful- ness even if it could be satisfactorily answered” ( ). though brodie refers respectfully to jordan in the opening paragraph of her acknowledgements, she strongly disagrees with his view of “jefferson’s miscegenation.” jon meacham provides thorough documentation on this matter ( – ). joseph ellis, a skeptic as late as regarding the relationship (see american sphinx – ), asserted in , “if history is an argument without end, skeptics and agnostics will still have a role to play in the debate. but the new scholarly consensus is that jefferson and hemings were sexual partners” ( ). the publication of paula byrne’s belle and the release in the same year of the same-titled movie emphasizes the current interest in a true story of a light-skinned daughter of an african slave woman raised in the household of her politically powerful guardian. dido belle, whose father is a british naval captain, is raised by her great-uncle, the earl of mansfield, and comes of age at the same time that the earl, who serves as england’s lord chief justice, must render a verdict in the zong appeal, the case in which a british slave-trading firm sought insurance company compensation for the human filling in gaps in the historical record “cargo” who had been tossed overboard on the middle passage in . granted, notable differences between the circumstances of belle and harriet hemings exist: to note one crucial fact, belle’s guardian wielded substantial political power, whereas jefferson’s authority to continue or correct america’s treatment of slaves effectively ended a full decade prior to the events rinaldi—through harriet—narrates. byrne frequently does remind her readers, though, that reasonable speculations must be relied upon when historical evidence is thin or nonexistent, as in this admission: “we simply don’t know whether dido belle was conceived by force, by mutual consensual passion, or as a ‘duty’ that might bring material benefits to her powerless mother” ( ). rinaldi might admit the same regarding sally’s children. byrne acknowledges that the “only way of glimps- ing [dido belle’s] life is through the lives of others” ( ). this parallels rinaldi’s task in creating an authentic version of harriet hemings, who engages in many dialogues with others who attempt to influence her. the movie belle takes considerable liberties with the available historical evidence and may be played off against byrne’s book: time sequences are compressed, and belle’s romantic life unfolds along with the debate about the zong decision. this essay examines harriet’s in-between status. curiously, the movie indicates that belle fluctuated in an uncomfortable in-between status in the mansfield household, allowed neither to dine with the family nor eat in the kitchen with the ser- vants, for example. yet as a further reminder of the instability of all “texts,” whether a novel, a movie, or a historical document, byrne asserts that proof is lacking that belle “was normally excluded from family meals” ( ). madison’s memoirs, which were first published in an ohio newspaper in , run for just four pages and are included as an appendix in brodie’s biography, the selected writings of thomas jefferson, and gordon-reed’s thomas jefferson and sally hemings. some caution should be used, though, if his brief text were brought into a classroom: madison refers to harriet’s life post-monticello, and many readers would prefer not to know what he says until after finishing the novel. in , jefferson returned to monticello from washington in order to be with his fatally ill daughter maria, the daughter sally hemings had escorted to france to visit jefferson in . “it is quite telling that he turned to hemings during one of the most heartbreaking periods of his life, when he was a veritable portrait of emotional devasta- tion. madison hemings’s conception in the harrowing six weeks jefferson was at home to attend to his daughter shows that this extremely sensitive man sought the comfort of the familiar with the person who understood better than anyone besides his daughter martha what maria had meant to him” (gordon-reed, the hemingses of monticello ). for example, in an early scene harriet intends to exit the house by walking past the underground kitchen, which would seem to place her as emerging from the servants’ rooms under the south terrace, in contradiction to the later references to her third floor room ( ). sally, in the kitchen, sees harriet and tells her to serve a tray of food to thomas mann randolph in the dining room. together, mother and daughter move “through the underground corridor” and then harriet alone ascends “the stairway to the hall outside the dining room” ( , ). (the website www.monticello.org provides a virtual tour of the house and enables viewers to track many of harriet’s movements.) harriet conducts five dialogues with jefferson, and for four of these the location is specified: two in his sanctum sanctorum, one overlooking the east balcony, and one by the carriage as she leaves monticello. (another exchange is brief, with the location of their meeting not specified.) rinaldi’s depiction of people’s circulation in and around the great house may seem contrived at times. typically, though, the author stipulates why harriet enters a specific location, such as when sally directs her to move from the kitchen up to the entrance hall overlooking the east balcony to speak with jefferson ( ) or to serve food to thomas mann randolph, or when randolph directs her to serve tea to thad sandridge ( – ): these set-up meetings are presented as highly unusual, as are harriet’s exchanges with jefferson in his sanctum sanctorum. brian dillon on harriet’s ancestry, see gordon-reed, the hemingses of monticello and stanton, “those who labor for my happiness.” on slaves bequeathed to jefferson upon his marriage, see gordon-reed, the hemingses of monticello and ellis . the telescope incident is recalled in meacham – . rinaldi relied, of course, on brodie and earlier authors. on callender, see ellis – , gordon-reed, thomas jefferson and sally hemings, and meacham – . on bankhead, see stanton , gordon-reed, the hemingses of monticello – , and kierner – . though pursuing this topic may be too “weighty” (to again use honey’s term) for ya readers, the following information certainly is useful. according to lucia stanton, “the extreme imbalance of power in a slave society made the whole idea of consent, when it concerned a female slave and a free white man, especially if he owned her, an absurdity. nevertheless, it is apparent that interracial sex in virginia and elsewhere in the south took every form from the most cruel exploitation to the most enduring affection” ( ). alan taylor notes, “no law punished masters who raped slave women or kept them as concubines. neighbors did little more than gossip so long as a master kept a low profile and did not marry a slave partner: a model of discretion set by jefferson” ( ). see brodie and ellis – . though acknowledging the “anxiety and rage that afflicted him in middle age,” cynthia kierner adopts a more empathetic view: she notes his debts, both inherited and created during his marriage to martha; his lack of a dowry for some of his younger daughters, which inhibited their marriage prospects; the viciousness of his son-in-law bankhead; and the difficult position he maintained as the son-in-law of jefferson while residing at monticello ( ). barbara chase-riboud’s best-selling novel sally hemings piles up the references to thomas mann randolph as a drunken fool accruing severe financial debts. curiously, rinaldi does not refer to this novel in her bibliography. as randolph should have been aware before he began the first of his three one-year terms of office, the authority of virginia’s governor “had been clearly and deliberately limited by the framers of the constitution of ” (gaines ). thus his proposal may have been evident even to randolph as more provocative than practical. by modern standards, it certainly could not be labeled progressive: fearing violent slave rebellions, “he suggested that ‘a fair proportion’ of slave youths in the different parts of virginia be manumitted every year. to accelerate the process, he recommended further that ‘a double proportion of females’ over males be released annually.” he wanted “those manumitted under his program [to] be sent to the island of santo domingo, which was ‘sufficiently near to admit of emigration at little cost,’ and where a self-governing com- munity of liberated negroes was already in existence” (gaines ). see brodie, – and gordon-reed, thomas jefferson and sally hemings . see gordon-reed, thomas jefferson and sally hemings – . gordon-reed offers these valuable insights that apply not only to harriet but to her mother, her aunts, her grandmother, and her great-grandmother: “throughout their time at monticello, none of the hemings women married men from ‘down the moun- tain’ who worked in the fields. they were either in long-term liaisons with high-status white males or white workers at the plantation, or they married household servants from other plantations who were also mixed race or, in the case of critta hemings [sally’s older sister], a free black man. one could say that these women had no choice regard- ing the white men, even the men who did not own them. it is also possible, of course, that given a choice they would have preferred white mates. that might be a disturbing thought from a modern perspective, with our knowledge of slavery and views about the value of solidarity in the face of oppression. this possibility, however, must not be discounted outright, especially in light of the behavior of some of the hemings children and grandchildren” (gordon-reed, the hemingses of monticello ). madison’s memoirs assert that sally was impregnated by jefferson while in france, that she delivered the child after they returned to virginia, and that the child died soon filling in gaps in the historical record thereafter. also, gordon-reed asserts that her analysis “tended to support madison hemings’s version of his family story: sh had a child in , but that child did not live. there are no records of a child named thomas linked to sh in tj’s farm book, even in the years before sh and tj’s relationship was exposed to the public.” she also exam- ined the records of vaccinations against small pox that jefferson maintained: “jefferson vaccinated his children beverley and harriet in , and madison and eston in . all four are listed as children of sally hemings. there is no hemings child named tom on the list, as he certainly would have been had he existed. again, these vaccinations began well before callender ever wrote about a child named tom at monticello.” see gordon-reed, the hemingses of monticello – n. tom is referred to on pp. – , , , – , , , , and . an instructor intent on challenging rinaldi’s depiction of jefferson in this exchange that refers to tom, or other scenes, could turn to any of the jefferson documents already noted (from his letters and notes) in order to position jefferson’s own writing against this fictional version. this would allow young readers, especially, to assess rinaldi’s accuracy and to begin to recognize the slipperiness of historical “truth.” see meacham – , n. gordon-reed refers to a balloon flight in petersburg, virginia, in perhaps that might be attributed to beverly. jefferson’s own interest in balloon flights extends over decades and is well documented. “by today’s standards ballooning may seem a trivial activity, a thing of sport. during jefferson’s era it was considered a scientific venture with travel and even military implications. it would be intriguing if he passed his interest in aerial transportation on to beverly and madison hemings, all the more so if beverly undertook to become a balloonist” (thomas jefferson and sally hemings ). the circumstances of the trial of wythe’s grandnephew are more complicated than jefferson’s “lesson” to beverly indicates. the forensic reports by three of richmond’s leading doctors who performed an autopsy of wythe proved to be incompetent: they did not establish that he had been poisoned (chadwick – ). “they did not perform any of the standard tests to discover arsenic and even ignored the simple -year-old taste test that would have at least alerted them to a poison of some kind. the autopsies that should have conclusively proved that arsenic was responsible for the deaths of michael brown and george wythe were, in short, colossal forensics failures” (chadwick ). also, virginia’s governor at the time shared privileged information with the defense counsel, which also weakened the prosecution’s case (chadwick ). when beverly left in , there is no evidence “that jefferson tried to bring him back” (gordon-reed, thomas jefferson and sally hemings ). had wythe died and michael brown lived, jefferson would have faced a circumstance that may have contrasted with how he treated his four hemings’s children: “how would jefferson have carried out wythe’s final request about his involvement with michael brown? would he really have brought the african american boy to monticello or to the president’s house to continue his studies, or would he have used the money from wythe’s estate to hire tutors for him? brown at monticello would indeed have been an interesting and problematic sight” (gordon-reed, the hemingses at monticello ). delegates to the continental congress “eliminated entirely jefferson’s long pas- sage on the slave trade. in the notes he kept of congress’s proceedings, jefferson said that change was made ‘in complaisance to south carolina & georgia,’ which had never tried to restrain the slave trade and, indeed, wanted it to continue, with the consent of ‘northern brethren’ who had few slaves but were sensitive on the issue because they had been ‘pretty considerable carriers of them to others.’ maybe so, but the very acknowledg- ment that colonists had been in the past or were at present willing participants in the slave trade undermined the assertion that ‘the christian king of great britain’ was alone responsible for that outrage on humanity” (maier ). brian dillon the farm book has been examined in ways that jefferson could not possibly have anticipated: “it is, in fact, highly unlikely that it ever occurred to jefferson that his record of the lives of his slaves would become the subject of scholarly interest, even a passion among some—that his slaves’ lives would be chronicled and followed in minute detail, the interest in them often unmoored from any interest in him. . . . in jefferson’s monumentally patriarchal and self-absorbed view, one shared by his fellow slave-owning planters, this was oh, the responsibilities i have! here is what i have done and have yet to do for all ‘my family’” (gordon-reed, the hemingses of monticello ). among a variety of outcomes that resulted when some member(s) of a family chose to pass, stanton identifies the following: “important life passages like births, marriages, and deaths became painful reminders of family division, and only those remaining in the black community came to family reunions” ( ). though she appears in only three brief episodes when harriet seeks her at her mulberry row cabin, mammy ursula’s role deserves attention. this “superannuated” woman avoids the race-segregated sunday baptist services where the white minister tells the slaves to obey their masters: this hints at her positive mentoring role ( ). she lived at monticello even before jefferson and his wife first moved there ( ). she not only validates harriet’s decision to leave but seems to support her decision to pass, as though she may live vicariously through harriet: “i’se part of this place. but you ain’t. you, chile, is part of somethin’ else. somethin’ new. out there. go. however you wants. for all of us” (emphasis added, ). eston lived as a black man near madison in ohio until he moved his family to wisconsin, passed for white, and changed his name to e.h. jefferson. in his memoirs, madison said, “eston married a colored woman in virginia, and moved from there to ohio, and lived in chillicothe [ohio] several years. in the fall of he removed to wisconsin, where he died a year or two afterwards. he left three children” (qtd. in gordon-reed, thomas jefferson and sally hemings ). note all the information that is missing, including the vagueness—and inaccuracy—of the death date: eston died in . there is no follow-up regarding what eston and his family did after they left ohio, no awareness that eston’s sons ran madison, wisconsin’s oldest hotel or that they served in the military during the civil war (stanton – ). the implication seems to be that communication between madison and his brother and his brother’s children ceased after eston left ohio and passed. many biographers address the linked issue of jefferson’s expensive tastes and sub- stantial debts. jack mclaughlin comments, “in spite of his exacting eye for the details of income and expenditure, he seldom stepped back to observe his economic landscape. because he notched each financial tree, he thought he knew the forest; until it was too late, he had little idea of his net worth.” though he received an annual salary of $ , while serving as president, it apparently was not evident to him “that he was living well beyond his income during his eight years in the presidency, and that a day of reckoning must come” ( ). gordon-reed offers this practical opinion that applies to the conse- quences experienced by both martha randolph and her children and sally’s children: “parents are expected to attend to the well-being of their children; it is, in fact, seen as their highest duty. jefferson’s handling, or, more accurately, not handling, of his finances in the final two decades of his life conflicted with that duty. why wouldn’t jefferson’s actions on this score count as examples of insufficient regard for his family?” (thomas jefferson and sally hemings ). curiously, the title of john chester miller’s book, which rinaldi “borrows,” is a metaphor derived from this same letter jefferson wrote in in regard to the mis- souri controversy (and both miller and rinaldi include a brief passage from the letter in their epigraphs). he believed slavery would only end if the slaves were expatriated. “but as it is, we have the wolf by the ears, and we can neither hold him, nor safely let him go. justice is in one scale, and self-preservation in the other.” he closes his letter with a filling in gaps in the historical record remarkable emotional mixture of self-congratulation, sorrow, and blame: “i regret that i am now to die in the belief, that the useless sacrifice of themselves by the generation of , to acquire self-government and happiness to their country, is to be thrown away by the unwise and unworthy passions of their sons, and that my only consolation is to be, that i live not to weep over it. if they would but dispassionately weigh the blessings they will throw away, against an abstract principle more likely to be effected by union than by scission, they would pause before they would perpetuate this act of suicide on them- selves, and of treason against the hopes of the world” (letter to john holmes ). is it too extravagant a point to claim he foresees the violent division within his own country and among his own descendants? works cited brodie, fawn. thomas jefferson: an

(kent, ohio: kent state university press, . xiv, pp. cloth $ . , isbn - - - - .) with his biography of martin davey, frank vazzano sets out to tell the “good story” of a “very, very interesting man” (x). he accomplishes this goal admi- rably as an “unabashed story teller” and as an historian. certainly, no one knows davey better than the author who has written three articles about davey’s terms as governor, all of which appeared in ohio history. an effective biography not only examines the subject’s life but also the nature of place and time and the meaning of change. as the title indicates, vazzano understands this well. vazzano is especially successful in describing davey’s life and times during his formative years and early career during the late nineteenth and the early twentieth centuries. born of an immigrant father obsessed with the apparently quixotic quest for scientific tree care and raised in poverty in small town kent, ohio, davey grew to manhood as a gifted salesman and businessman, community booster, and brilliant politician. vaz- zano captures the transformation of davey during changing times as he turns his father’s vision into a successful business with customers across much of the nation and helps “boost” kent from a nineteenth-century village with dirt streets to a modern community with all the amenities of public services. vazzano successfully captures the emergence of modern america and the nature of local politics. barely out of his teens, davey is traveling to cleveland to sell his father’s book, the tree doctor, and then new york to promote the davey tree expert company. he boldly cultivates captains of industry, wins the tree care of the capitol grounds, and uses advertising to creatively expand the reach of the business. at the same time, vazzano aptly shows davey mastering local politics: the network of friendships and personal alliances, the use of patronage to reward friends and define politi- cal power, the necessity of strong organization, and the efficacy of public speaking. he was elected mayor of kent, served well, and, as countless poli- ticians before and after him, used that base to win higher office. although one of ohio’s most successful politicians in the twentieth cen- tury who served multiple terms as mayor, in congress, and as governor of ohio, davey remains elusive as a political leader. vazzano documents davey’s brilliance and limitations as a politician; his organizational skills, his tireless wp-p m- .ebi.ac.uk params is empty sys_ exception wp-p m- .ebi.ac.uk no params is empty exception params is empty / / -

editörden ______________ editorial geleceğin kütüphaneleri türk kütüphaneciler demeği tarafından üç ayda bir yayımlanan türk kütüphaneciliği dergisinin editörü olarak, - ağustos tarihleri arasında yapılacak olan . ifla konsey ve genel konferansına katılmak üzere dünyanın dört bir yanından güzel kentimiz İstanbul’a gelen seçkin meslek­ taşlarımıza hoş geldiniz demekten büyük onur duyuyorum. ifla genel merkezi ve onun profes­ yonel kurulu, ifla’ ulusal düzenleme komitesi ile birlikte, bu yıl da olağanüstü bir program hazırladılar. İstanbul’da bulun­ dukları süre içinde herkesin (ister mesleki ve sosyal etkinlikler, ister gezi turları olsun) izlemeye değer birşeyler bulacağını umut ediyoruz. ifla konferansının teması, “geleceğin kütüphaneleri,” çok uygun seçilmiş. Çünkü kütüphane ve bilgi hizmetlerinin sağ­ lanmasında daha önce örneği görülmemiş gelişmeler ve değişiklikler yaşıyoruz. bugünlerde “bilgi çağı,” “bilgi toplumu,” “sanayi ötesi toplum” gibi terimleri sık sık duyuyor ve kullanıyoruz. Çoğu kimse bilginin karar vermedeki rolünü teslim etmektedir. “bilgi” giderek artan biçimde bir ürün olarak değerlendirilmektedir. bir toplumun ne kadar bilgi “tüketirse” ekono­ mik yönden o denli gelişeceğine inanıldı­ ğından, herkesin istekli birer “bilgi tüketicisi” olması beklenmektedir. dahası, bilgi gsmh’nin geliştirilmesi için enerji kadar önemli ve değerli görülmektedir. Örneğin, yüzyılımızda tarımsal üretimde libraries of the future as the editor of the türk kütüphaneciliği, a quarterly journal published by the turkish librarians association, i am honored to welcome our distinguished colleagues from all over the world to the beautiful city of istanbul to take part in the st ifla council and general conference from - august . once again, the ifla hq and its professional board, along with the ifla’ national organizing committee, put together an outstanding program this year. we hope that everyone would find something worthwhile to pursue (be it professional and social activities or sightseeing tours, to name but a few) while staying in istanbul. the theme of the st ifla conference, “libraries of the future,’’ was chosen aptly as we have been experiencing unpre­ cedented developments and changes in the provision of library and information services. nowadays we often hear and use such terms as “information age,” “information society," and “post-industrial society” in our daily life. most people recognize the role of information in decision-making as “information” is increasingly treated as a commodity. everybody is expected to become an avid “information consumer” as it is believed that the more information a society “consumes,” the more developed it becomes economically. furthermore, information is seen as valuable and important a resource yaşar tonta meydana gelen artışın fiziksel kaynakların ar tışına değil, büyük oranda yeni bilgi kullanımına bağlı olduğu bilinmektedir. ekonomik kalkınma ile bilgi erişim olanaklarının varlığı arasındaki ilişkiyi fark eden ülkeler kütüphane ve bilgi merkezlerini gelişmiş teknoloji ürünleriyle donatmak için bilgi teknolojisi alanında önemli yatırımlar yaptılar. bu ülkeler çok değişik format- lardaki bilgi kaynaklarının seçimi, düzen­ lenmesi ve bu bilgilere erişim için kütüphaneci ve bilgi profesyonellerinin uzmanlığına gereksinimi olduklarının da farkına vardılar. diyelim ki on yıl önce “gopher” ve “web” gibi internet hizmetleri aracılığıyla saat kullanıma açık tutulan dijital kütüphanelerimizin olacağını kim tahmin ederdi? türk kütüphanecilerinin evlerindeki koltuklarından bile kalkmadan louvre müzesinin koridorlarında dolaşıp oradaki sanat yapıtlarını inceleyeceklerini kim tahmin ederdi? bir gün “bilgi otoyolu”na çıkıldığında, birkaç örnek vermek gerekirse, kütüphane ve bilgi mer­ kezlerindeki, sinema ve tv arşivlerindeki, coğrafık bilgi sistemlerindeki, eğit'm, sağlık ve adalet konusundaki veri taban karındaki her tür bilgiye (metin, grafik, ses ve hareketli görüntüler içeren çoklu ortam) erişebileceğimizi kim tahmin ederdi? sanırım çok az kişi.. ekonomik kalkınma ile bir ülkedeki bilgi teknolojisi araçlarının varlığı arasında nasıl bir ilişki varsa, bilgiye özgürce erişim ile demokrasi arasında da bir ilişki olduğu gözlenmektedir. bu ilişkiyi çok önceleri fark eden thomas jefferson, bilgiyi “demok­ rasinin değer birimi” olarak nitelendirmiştir. bu yaklaşımı benimseyen ve demokrasilerin ancak bilgili vatandaşlar tarafından geliştirilip güçlendirilebileceğini fark eden ülkeler bilgi edinme özgürlüğünün önündeki tüm engelleri kaldırmakta ve kütüpha­ nelerini ve bilgi merkezlerini büyük ölçüde desteklemektedirler. as energy for the development of the gnp. for instance, it is known that the increase in the agricultural productivity within the last century is primarily due to the use of new information, not because of increase in the physical resources. countries that have noticed the relation­ ship between the economic development and the availability of information access and retrieval capabilities have invested heavily in information technology to equip their library and information centers with fairly developed technological products. they also realized that they needed the expertise of library and information professionals to cope with the selection, organization and retrieval of information sources available in a multitude of format. who would have thought, say, ten years ago that we would have digital libraries that are open to public hours a day through the internet services such as gopher and the world-wide web? who would have thought that turkish librarians would stroll through the corridors of the. louvre museum virtually and explore some of the artwork there without even leaving their seats at home? who would have thought that one day, once on the “information superhighway,” one could get access to all sorts of information (textual, graphical, multimedia including sound and live pictures) that are available through libraries and information centers, cinema and tv archives, geographic information systems, education, health and justice databases, to name just a few? very few> people would, i reckon. just as there is a relationship between the level of the economic development and the availability of information technology tools in a given country, there appears to be a strong relationship between democrat­ ization and the freedom of access to information. thomas jefferson, who noticed this relationship long ago described in- editörden / editorial ancak, bilgiye erişimle demokrasi ve ekonomik kalkınma ile bilgi teknolojisi kolaylıklarının varlığı arasındaki bu olumlu ilişkilere karşın, insan, yine de, kendi aramızda barışı sağlama ve koruma konusunda katedeceğimiz uzun bir yol olduğunu düşünmekten kendini alamıyor. bir yandan, başka ülkelerdeki çevrimiçi ve dijital kütüphanelere ve bilgi kaynaklarına hemen hemen hiçbir engelle karşılaşmadan anında erişim sağlamak ve bu erişimi sürekli kılmak bizim için çok önem taşıyabiliyor. Öte yandan, bu çevrimiçi bilgilerin ana kaynağı ve bilgi ile kültürün fiziksel yapıtları olan kütüphane, arşiv ve müzelerin tahrip edilmesine karşı daha az duyarlı olabili­ yoruz. kütüphaneler, arşivler ve müzeler geçmişte her zaman demokrasinin kaleleri olmuş ve bundan bütün uluslar eşit biçimde yararlanmışlardır. ancak demok­ rasinin kaleleri bosna-hersek’te uygar dünyanın gözleri önünde yerle bir edil­ meye ve yakılmaya devam edilmektedir. buna izin vermemeliyiz. İstanbul’da ileriye bakıp geleceğin kütüphaneleri hak­ kında düşünürken, şimdiki ve geçmişteki kütüphanelere de bakalım. profesör riedlmayer’in dediği gibi: “kütüphane ve arşivlerin yakılması, doğrunun ortada bir yerlerde olduğunun farzedildiği iki taraflı bir siyasi anlaşmazlıkta taraflardan birinin görüşlerini ifade etmesi şeklinde değerlendirilemez.” bu hain eylemleri kınıyor ve tüm meslektaşlarımızı çok geç olmadan bu tür eylemlere karşı çıkmaya çağırıyoruz. değilse, uzun vadede bundan hepimiz zarar göreceğiz. andrâs riedlmayer, “erasing the past: the destruction of libraries and archives in bosnia- herzegovina,” middle east studies association bulletin ( ): - , july . riedlmayer’in maka­ lesinin türkçe çevirisini bu sayıda bulabilirsiniz. türk kütüphaneciliği*nin ifla’ formation as the “monetary value of democracy." countries which have adopted this approach and noticed that democracies can only be developed and strengthened through informed citizens, abolish all barriers before the freedom of information and support their libraries and information centers to a great extent. one cannot help but think, however, that, despite the positive inter­ relationships between the freedom of access to information and democracy, and between the economic development and the availabiliy of information retrieval facilities, it appears that we have a long way to go in protecting and preserving the peace among ourselves. on the one hand, it may be tremendously important for us to get access to the online and digital libraries and information sources of other countries within a fraction of a second with virtually no boundaries, and keep it that way. yet, on the other hand, we may be less sensitive against the destruction of physical artefacts of information and culture such as libraries, museums, and archives which are the main sources of most online and digital information in the first place. library and information centers, archives, and museums have always been the bastions of democracy in the past and all the nations have benefitted equally from that. yet the bastions of democracy continue to be burned and leveled to the ground in bosnia-herzegovina before the very eyes of the civil world. we must not allow this to happen. while looking ahead and contemplating about the libraries of the future here in istanbul, let’s look also at the libraries of the present and the past. as professor riedlmayer puts it: “the burning of libraries and archives cannot be construed as a mere expression yaşar tonta Özel sayısıyla ilgili olarak da birkaç söz söylemek istiyorum: türk kütüphaneleri ve arşivleri hakkında çeşitli makalelerin yanı sıra her zamanki yazıları da içeren bir özel sayı hazırladık (üniversite, halk ve okul kütüphaneleri, kütüphanecilik eğitimi, yazma ve nadir eser kütüphaneleri, türk arşiv araştırmaları, vd.). Özel sayı yayımlama düşüncemizi destekledikleri ve maddi kaynak sağladıkları için ifla‘ ulusal düzenleme komitesi başkanı ve üyelerine teşekkür etmek isterim. yardımcı editör olarak aramıza katılan meslektaşımız müjgân Şan’a da hoş geldin diyorum.

which upregulation of bcl affects earlier steps of bax- mediated apoptosis are not fully understood. we found that bax insertion into the mom was the earliest apoptotic step inhibited by bcl overexpression. paradoxically, we also found that bax translocation to the mitochondria was not inhibited but rather spontaneously increased in this same genetic context. this increase in mitochondrial associated bax required a physical interaction be- tween bax and bcl . we therefore propose that, at least when upregulated, bcl behaves as a ‘decoy receptor’ which sequestrates bax at the mitochondria but inhibits its insertion into the mom, committing the cell to survive. supported by nyu research challenge funds to ld. -pos compartmentalization of bcl family proteins mediated by organelle lipid membranes rebecca j. boohaker, ge zhang, adina loosley, kathleen nemec, annette r. khaled. university of central florida, orlando, fl, usa. cancer is defined by a pronounced inhibition of cell death. the bcl family of proteins tightly regulates the delicate balance between life and death. one method of regulation is the compartmentalization of antagonistic members. for example, bax, a pro-apoptotic member of this family, acts as the penulti- mate factor in the apoptotic cascade by releasing apoptogenic factors such as cytochrome c from the mitochondrial lumen. the normally cytosolic protein translocates from one internal compartment to another through an elusive mechanism. individual organelles are defined not only by function (mediated by specific membrane bound proteins), but by the unique composition of their phospholipid membranes. in this work, we have evaluated the contribution of organelle lipids to the localization of of bcl proteins. -pos in search of the structure of mac in the mitochondrial outer membrane pablo m. peixoto , christian renken , shefali haldar , carmen mannella , kathleen w. kinnally . new york university college of dentistry, new york, ny, usa, wadsworth center, albany, ny, usa, academy of the holy names, albany, ny, usa. several groups have tried to determine the structure of the channel (mac) formed in mitochondrial outer membranes (om) of apoptotic cells or in syn- thetic membranes by bax and related proteins/peptides, using electron micros- copy (em), atomic force microscopy and x-ray diffraction. here, pore-like structures ~ - nm were handpicked from transmission em images of ura- nyl-acetate-stained oms isolated from control and apoptotic (il -deprived) fl . cells. these ‘‘candidate pores’’ were aligned by correlation procedures, and class averages defined by principal component and k-means analyses. main differences in the class averages were ( ) the presence of one or more dark (stain-filled) pores, and ( ) the nature of white (stain excluding) features around the pores. a class average consisting of a single -nm pore with pro- nounced white rim was rotationally averaged and used as a reference for cross-correlation searches of om images from control and apoptotic cells. searches using this -nm ‘‘donut’’ motif and the same motif doubled in size ( -nm ‘‘donut’’) yielded thousands of ‘‘hits’’ in both control and apoptotic membranes, which were subsequently aligned and classified as before. the pre- dominant stain-filled structures found with both motifs were not circular but elongated (up to ~ x nm), extending away from stain-excluding crescent- shaped features. the radial anisotropy ruled out reference bias and was in- consistent with pores formed by rings of evenly spaced protein subunits. we hypothesize that the different classes of structures detected represent stages in formation of mac as an increasingly large membrane bilayer defect (or ‘‘cleft’’) induced by successive aggregation or clustering of bax/bak molecules. a progressive assembly mechanism for mac has been recently suggested by real-time monitoring of mac conductances in isolated mitochondria by patch clamping (martinez-caballero et al. j biol chem : - ). supported by nih grant gm . -pos effects of mac formation on mitochondrial morphology pablo m. peixoto, shin-young ryu, robert range, kathleen w. kinnally. new york university college of dentistry, new york, ny, usa. accumulating literature associate mitochondrial dynamics with apoptosis, since regulation of either process has reciprocal effects. these processes seem to converge in formation of the mitochondrial apoptosis induced channel, mac, which releases cytochrome c and triggers the degradation phase of apo- ptosis. while bax and bak, core components of mac, were shown to interact with fusion and fission proteins, some studies also suggest proteins from the in- termembrane space could leak to the cytosol and further promote mitochondrial fission during apoptosis. the temporal relationship between apoptosis induc- tion, mac formation and mitochondrial fragmentation was investigated by time lapse microscopy. mac function was induced through staurosporine treat- ment and microinjection of tbid or cytochrome c. mac formation and mito- chondrial dynamics under these conditions were monitored in hela cells (clone ) that stably express low levels of gfp-bax and were transiently transfected with a pdsred- plasmid. gfp-bax relocation to mitochondria only during apoptosis signals mac formation, while pdsred- expression shows mito- chondrial structure as red fluorescence. treatment with staurosporine and microinjection with tbid or cytochrome c induced relocation of bax and col- lapse of the mitochondrial network. the temporal relationship between these two events was further analyzed. interestingly, pretreatment with imac , a spe- cific mac blocker, protected against cell death and prevented mitochondrial fragmentation after tbid injection. our results suggest a link exists between mac formation and collapse of the mitochondrial network during apoptosis. supported by nih grant gm . -pos mechanism of the mitochondrial cytochrome c release wave in bid-induced apoptosis soumya sinha roy, cecilia garcia-perez, erika davies, xuena lin, györgy hajnóczky. thomas jefferson university, philadelphia, pa, usa. bid, a bh -only bcl family protein, plays a central role in apoptosis. bid is cleaved by caspase- and other enzymes forming tbid that induce mitochon- drial outer membrane (omm) permeabilization and cytochrome c (cyto-c) re- lease. however a mystery remains how bid synchronizes the function of a large number of discrete organelles, particularly in mitochondria-rich liver or muscle cells. here we showed that tbid ( . - nm) elicited progressive omm perme- abilization and complete cyto-c release with a dose-dependent lag time and rate in h c cell populations. once started, the omm permeabilization was not pre- vented by tbid washout. in contrast, the dose-response for digitonin-induced omm permeabilization displayed quantal behavior. in single cell imaging studies, permeabilized h c and primary human cardiac cells transfected with cyto-c-gfp showed complete tbid-induced cyto-c-gfp release closely followed by mitochondrial depolarization. the cyto-c-gfp release started at discrete sites and propagated through the mitochondria with a constant velocity and a relatively stable kinetic of release in each organelle. similar tbid-induced cyto-c-gfp release wave was documented in intact h c cells transfected with tbid. the waves were not dependent on ca þ , caspase activation or permeabil- ity transition pore opening. however, treatment with mntmpyp, a ros scav- enger or overexpression of mitochondrial superoxide dismutase suppressed the coordinated cyto-c release and also inhibited tbid-induced cell death. on the other hand, both superoxide and hydrogen peroxide sensitized mitochondria to the tbid-induced permeabilization. thus, tbid engages a ros-dependent inter-mitochondrial signaling mechanism for spatial amplification of the apoptotic signal by mitochondrial waves. -pos role of milton domains in the calcium-dependent regulation of mito- chondrial motility sudipto das, gyorgy hajnoczky. thomas jefferson university, philadelphia, pa, usa. the mammalian grif and oip , and the drosophila milton are kinesin- binding proteins that form a complex with the miro gtpase, an outer mitochon- drial membrane ef-hand protein, to support the movement of mitochondria along the microtubules. our study demonstrates that in h c cells overexpress- ing oip or grif , the basal motility of mitochondria is increased, whereas the sensitivity to calcium-induced movement inhibition is decreased. to dissect the interaction between milton, kinesin and miro, three different milton constructs were tested: milton ( - ), the soluble domain of milton; milton ( - ), lacking the kinesin heavy chain binding site and milton ( - ) that lacks additional ~ amino acid presumably containing part of the miro binding site. immunohistochemistry revealed that the overexpressed milton ( - ) was cytoplasmic, whereas the other two milton constructs showed mitochondrial localization. the basal mitochondrial motility was in- creased by milton ( - ) but was not altered by milton ( - ) or mil- ton ( - ). a plot of mitochondrial motility against slowly rising cytoplasmic [ca þ] induced by thapsigargin ( mm), shows that overexpression of milton ( - ) significantly reduced the calcium sensitivity of mitochondrial motil- ity reminiscent of oip and grif . by contrast, milton ( - ) or milton ( - ) did not have any effect. the thapsigargin-induced cytoplasmic calcium signal was not affected by any of the milton constructs. these data indicate that compartmentalization of bcl family proteins mediated by organelle lipid membranes in search of the

is an emerg- ing clinical and research measure of retinal nerve fiber layer (rnfl) loss in multiple sclerosis (ms) and may reflect neuro- degeneration. few studies capture the effect of disease duration on the rnfl in subjects without exposure to disease-modulating therapies. we assessed the relationship of rnfl loss with dis- ease duration in subjects with untreated ms and determined if such loss paralleled corticospinal tract dysfunction in ms. sub- jects underwent oct (n = ) and visual testing (n = ). either they were either examined or they participated in a vali- dated telephone interview so we could determine their expanded disability status scale (edss) scores. both rnfl thickness (spearman rs = – . , p < . ) and edss scores (rs = . , p < . ) correlated with disease duration. rnfl thick- ness correlated with edss scores (rs = – . , p < . ). in conclusion, rnfl loss correlates with disease duration and edss scores in subjects with untreated ms, indicating that oct may capture neurodegeneration. key words: disease duration, disease-modifying therapy, expanded disability status scale, multiple sclerosis, neurode- generation, optic nerve diseases, optical

magnetic resonance imaging (mri) lesion load neither correlate well with functional decline nor reflect cns neurodegeneration [ – ]. optical coher- ence tomography (oct) is under evaluation as an out- come measure of axonal degeneration for use in clinical trials and practice [ ]. oct is a noninvasive technique that uses infrared laser light to create cross-sectional images of the retina; this technique provides quantitative analysis of the retinal nerve fiber layer (rnfl) thickness (rnflt), macular thickness, and macular volume. the mechanism and reli- ability of oct are well described [ ]. oct detects changes in the rnfl, which contains unmyelinated axons subject to damage in glaucomatous and ischemic optic neuropathies [ ]; more recently, oct has been applied to optic neuritis (on) [ ]. short-term follow-up studies after acute on demonstrate an acute decrement of the peripapillary rnflt that plateaus by to months [ ]. oct also detects changes in the macula after on [ ]. the calculated macular volume includes the inner macular thickness, which contains the retinal ganglion cells presumably affected after on by a dying-back axonopathy, as seen in animal models [ ]. alternatively or additionally, primary neuronal degeneration may affect the retinal ganglion cells. oct has been shown to correlate with functional optic nerve measures such as multifocal visual-evoked potentials [ ] and low-contrast visual acuity (lcva) [ ]. as one of the longer white matter tracts in the cns, the optic nerve is likely to show the effects of both acute inflammation and neurodegeneration early in ms. on is the presenting symptom of ms in to percent of cases and eventually affects up to percent of patients during the illness, causing significant morbidity [ ]. rnflt in subjects with ms without a history of on is lower than in control subjects, indicating subclinical axonal loss [ , ]. thus, oct is an attractive candidate measure for capturing early changes in ms. the corticospinal tract is another long cns white matter tract frequently affected in ms. like the optic nerve, it is subject both to acute inflammation in the form of transverse myelitis and to neurodegeneration as seen by increasing gait dysfunction, mri atrophy [ ], and recently, gray matter demyelination on high-field mri [ ]. the expanded disability status scale (edss) is a standard measure of gait dysfunction and may correlate with other long tract signs, including rnfl loss and cog- nitive dysfunction [ ], although it poorly predicts long- term disability [ ] and its validity in relapsing-remitting ms (rrms) has been recently challenged [ ]. oct may provide a more sensitive research and clinically applicable measure to capture neurodegeneration in ms. most studies using oct have not accounted for the effects of disease-modifying therapies (dmts) on the rnfl, which may be significant if similar to dmt effects in early ms [ ]. we studied oct in subjects with ms of varying disease durations and with no expo- sure to dmts to test the hypothesis that in untreated ms, rnflt loss occurs both over the course of disease and in parallel with corticospinal tract dysfunction reflecting cns neurodegeneration. methods subjects the institutional review board approved all study procedures, and subjects gave their written informed con- sent. we recruited subjects over years of age from the thomas jefferson university comprehensive ms center (philadelphia, pennsylvania) and the neuro-ophthalmology service at wills eye institute (philadelphia, pennsylva- nia) with no exposure to dmt. subjects met revised mcdonald criteria for ms [ ]. we included subjects with clinically isolated syndrome if they fulfilled two or more modified barkhof mri criteria [ ]. we deter- mined disease-duration subject history. we considered neurological symptoms occurring before the diagnosis date to be caused by ms if they were of a typical nature (brainstem, spinal cord, visual, or multisystem), lasted for at least hours, and were unexplained by other neu- rological or systemic conditions. exclusion criteria included any dmt use, including interferon beta preparations, glatiramer acetate, natali- zumab, mitoxantrone, chemotherapeutics, or immuno- suppressants. we did not consider corticosteroid treatment a dmt for the purpose of this study, although the effects of corticosteroids on rnflt after on are largely unknown. of the subjects, had been treated with corti- costeroids before enrollment; only had received corti- costeroid treatment for acute on in the year before enrollment. we delayed enrollment in subjects with acute on for to months to allow the rnfl to stabilize [ ] and for at least month after intravenous corticosteroid treatment. we excluded subjects with comorbid systemic spain et al. retinal nerve thickness in untreated ms diseases that could mimic ms, ocular disease that might affect the oct results, or other abnormal fundoscopic findings unrelated to ms. we also excluded subjects with octs performed at nonparticipating facilities or who were unable to cooperate with testing. the primary end point was to establish a correlation between rnflt and disease duration. secondary end points included establishing correlations between edss scores and disease duration, rnflt and edss scores, and rnflt and both high-contrast visual acuity (hcva) and lcva and determining the effects of on history on these relationships. the study was powered on the pri- mary end point only. we calculated a sample size of subjects to achieve percent power to detect a moderate spearman rank correlation of . with a percent two-sided test. after study initiation, data regarding the normal age-related rnfl decrement of µm/decade over the age of years became available [ ]. we increased rnflt by a factor of µm for every decade over age for each subject, and we recruited additional subjects to allow for a lower correlation coefficient. we did not age adjust macular data because limited data on normative age-related decrements exists [ ]. of the subjects, we screened , enrolled , and then excluded an additional after enrollment, leaving subjects. screen failures were from lack of interest (n = ), dmt use (n = ), uncertainty of ms diagnosis (n = ), on within months of oct (n = ), comorbid sys- temic or ocular disease (n = ), clinically isolated syn- drome failing mri criteria (n = ), and oct from a nonparticipating facility (n = ). reasons for exclusion after enrollment were dmt use (n = ), clinically iso- lated syndrome failing mri criteria (n = ), on within months of oct (n = ), lack of informed consent (n = ), uncertainty of ms diagnosis (n = ), and comorbid ocular disease (n = ). history of optic neuritis prior studies have shown an absolute difference in rnflt based on individual eye on history [ , ]. we obtained on history in our study by subject report. because on history is subject to recall and other biases, we performed multivariate analyses considering the effect of individual eye on history and thinner side rnflt in the manner proposed by sepulcre et al., presuming the thinner side is most affected by inflammation [ ]. retinal imaging oct images were acquired with a stratus oct with (software version . , carl zeiss meditec, inc; dublin, cali- fornia) by trained technicians at the wills eye institute and thomas jefferson university, and dr. sergott reviewed them for quality. we dilated the subjects’ pupils with . percent phenylephrine hydrochloride and . percent tropicamide if a small pupil sized impaired image quality [ ]. we captured three . -mm diameter fast rnfl pro- tocol scans (scan length = . mm) centered on the optic disk for each eye. the stratus oct software calcu- lated mean rnflt values from each ° scan, and we averaged the three means for each eye using microsoft excel (version , microsoft corp; redmond, wash- ington) to reduce the influence of technical error during scan acquisition. the fast macular protocol (scan length = . mm, reliability within ± µm) used the average of six radial lines to compose a macular thickness/volume map. we reviewed additional fast optic disk and fast crosshair images to exclude other ocular pathologies. all images met the signal strength requirements of at least (maximum ) as per manufacturer recommendation. visual testing we measured the hcva of each eye with appropriate refraction using a retro-illuminated early treatment dia- betic retinopathy study chart (precision vision; la salle, illinois) at m, and we recorded m as the loga- rithm of minimum angle of resolution (logmar) acuity. we tested lcva at m and evaluated given data sug- gesting improved sensitivity for optic nerve dysfunction [ ] using a . percent low contrast sloan letter chart (precision vision). we determined the eye with greater visual impairment by logmar value; we considered eyes with equal logmar values equally impaired. corticospinal tract dysfunction dr. spain examined thomas jefferson university subjects (n = ) for their edss scores [ ]. because they were unavailable to be evaluated in the clinic, wills eye institute subjects (n = ) participated in a stan- dardized and validated telephone interview conducted by dr. spain that established their edss scores [ ]. statistical analysis we used spearman rank correlation to assess correla- tions between oct parameters, edss scores, visual jrrd, volume , number , acuity (va), and disease duration. oct parameters from each eye included the average rnflt; the thickness of the temporal, inferior, nasal, and superior quadrants of the rnfl; the total macular volume; and the minimum and average thicknesses of the fovea. we age-adjusted rnflt as described previously. we performed multivari- ate analyses to determine the effects of on history as described previously. we used the tukey test method to limit type error from performing more than one statistical test; individual p-values of . and . limited the overall type rate at . as indicated. we used analysis of variance to compare the mean rnflt for both eyes (ocu- lus uterque [ou]) between cohorts with and without on history. we performed statistical analyses using jmp, ver- sion . (sas institute, inc; cary, north carolina). results table shows subject demographics. wills eye institute subjects (n = ) were more likely to have rrms ( % vs %), on ( % vs %), a higher mean edss score ( . vs . ), and a lower mean rnflt ( . µm vs . µm) than thomas jefferson university subjects (n = ). we found no other systematic differences between recruitment sites. the distribution of subjects by disease duration demonstrated a wide spread, with subjects in the - to -year duration group, in the - to -year group, in the - to -year group, and in the > -year group. the rnflt ou correlated significantly with ms dis- ease duration (spearman rs = – . , p < . ) (figure (a) and table ). other oct parameters, including macular volumes and foveal thicknesses, did not demon- strate superior correlations with disease duration com- pared with the rnflt (table ). the inferior quadrant rnflt had the strongest correlation with disease dura- tion than any other sector, although all were significant (data not shown). while some studies suggest a greater absolute rnflt loss in the temporal sector [ ], others do not [ ]; as yet, little data exist to suggest differing regional rates of rnfl decline. corticospinal tract dysfunction as captured by edss also correlated with disease duration (rs = . , p < . ) (figure (b) and table ). finally, rnflt ou correlated with edss scores (rs = – . , p < . ) (fig- ure (c) and table ). we performed multivariate analyses to determine the effects of individual eye on history and the thinner rnflt on the correlations between rnflt and edss scores with disease duration. while rnflt differed sig- nificantly between eyes with a history of on ( . µm, % confidence interval [ci] . – . µm) compared with no history ( . µm, % ci . – . µm; p < . ) and between thinner ( . µm, % ci . – . µm) and thicker side ( . µm, % ci . – . µm; p < . ), neither had a significant affect on the relationship between rnflt or edss scores and dis- ease duration (table ). of note, of the subjects with known on had been affected bilaterally, thereby decreas- ing a possible on effect. interestingly, the on eye did not always demonstrate a more impaired oct; of sub- jects with monocular on, had a thinner rnflt and had a lesser macular volume in the opposite eye. as a proof of concept, va worsened at a lower rnflt. hcva was shown to correlate with rnflt (rs = – . , p < . , n = ) (table ), as did lcva (rs = – . , p = . ), although we tested fewer subjects using lcva (n = ). both on history and thinner-side rnflt influenced the va results, as shown by multivariate analyses (table ), although none reached significance after we applied the tukey test for multiple analyses. a categorical difference existed between subject cohort-based on history. the mean rnflt ou was sig- nificantly lower in subjects with a history of on ( . µm, % ci . – . µm) compared with in those without ( . µm, % ci . – . µm; p < . ) (figure ). the distinction in baseline rnflt based on subject on table . subject demographics. variable number (%) total ( ) thomas jefferson university ( ) wills eye institute ( ) female ( ) age (yr, mean ± sd) . ± .

(a) retinal nerve fiber layer thickness (rnflt) of both eyes correlates with disease duration. (b) expanded disability status scale (edss) scores correlates with disease duration. (c) rnflt of both eyes correlates with edss scores. “+” = subject history of optic neuritis (on), “×” = no subject history of on. jrrd, volume , number , short term cannot be evaluated in this cross-sectional design. furthermore, oct is a continuous physiological measure, while edss is an ordinal functional measure and thus not directly comparable. this study does, how- ever, provide baseline data for a prospective study of rnfl loss in subjects with untreated ms to assess the true rates of loss regarding on history and sensitivity to short-term changes. rates of rnfl loss need to be assessed in conjunction with whole brain or gray matter atrophy measures [ ] and more sensitive measures of cor- ticospinal tract dysfunction than the edss [ – ] so we can gain a comprehensive measure of the neurodegenera- tive component of ms. only then can neuroprotective strategies for preserving vision, gait, cognition, and the other debilitating effects of ms be more confidently tested. we found that peripapillary rnfl measures pro- duced stronger correlations with disease duration than did macular measures of thickness [ ] or volume [ ], which have been found in other studies to be more sensi- tive to the effects of on. further elucidation is required. correlations between rnflt ou and disease dura- tion were relatively modest. exclusion of subjects with clinically isolated syndrome based on mri criteria may have biased the subjects with shorter disease duration toward those with more advanced disease and potentially more rnfl involvement than a true early ms cohort. additionally, some of the subjects with longer disease duration, having chosen not to initiate dmt, may have been biased toward less severe disease and potentially less rnfl loss. the cross-sectional design of the study and heterogeneous subject population regarding ms type and stage of disease may also have influenced the strength of correlations. multivariate analysis using individual eye on his- tory and thinner rnflt side did not affect the relation- ships of rnflt and edss scores to disease duration, although this study was not powered to address these sec- ondary outcomes. this finding may indicate that subclin- ical on and/or ongoing neurodegeneration affect both optic nerves sufficiently to negate the influence of symp- tomatic on. interestingly, oct data contradicted the recalled history of on in one-quarter of subjects with lesser rnflt in the reportedly unaffected eye. a larger prospective study of rnfl loss is necessary to determine the character and tempo of neurodegeneration given on history. at a given time point, using the averaged rnflt ou may prove a more useful global measure of disease burden. the smaller baseline rnflt among subjects with a history of on as found in other trials may require sub- ject stratification by subject history of on rather than individual eye history of on in clinical trials [ ]. table . spearman

stronger correlations for hcva than lcva likely influenced by the unequal numbers tested (table ). overall, correlations between rnflt and va measures were sensitive to the effects of on and thinner rnflt side, although the study was underpowered to these sec- ondary outcomes. the poorer visual outcomes at lower rnflt underscore the need to measure and preserve reti- nal axons. larger prospective studies that include more sensi- tive measures of corticospinal tract dysfunction than the edss, coupled with advanced neuroimaging techniques and, ideally, histopathological investigations, will help detect differences in the pattern and rate of rnfl loss by disease subtype and on history, pointing to underlying pathological mechanisms of neurodegeneration [ , ]. studies comparing dmt-exposed (including corticoster- oids) and non-dmt-exposed subjects may help detect treatment effect on the rnfl. finally, improvements to the current to µm resolution of the stratus oct will have greater power to differentiate neurodegeneration from normal age-related losses to the rnfl, as well as any potential dmt effects on preserving crucial visual function in ms. conclusions in summary, we found rnflt to correlate with dis- ease duration in parallel with corticospinal tract dysfunc- tion, as measured by the edss in a population with ms untreated by dmts. subjects with on history had a lower baseline rnflt. this study suggests that oct may prove to be a useful instrument for capturing the cns effects of inflammation and neurodegeneration for use in both clinical trials and practice. table

church, va, usa objectives: evaluate the incremental impact of s. aureus infection stays on hospital charges and length-of-stay in u.s. hospitals in . methods: the nationwide inpatient sample data were analyzed. hospital discharges were classified as either a s. aureus–related infection stay or a non-s. aureus- related infection stay using a combination of several icd- codes. incremental effect of s. aureus infection on hospital charges and length-of-stay was estimated using multivariate regression models adjusting for hospital fixed effects and patient variables including age, gender, race,

gagne jj , maio v , goldfarb ni , horn dl , swanson r thomas jefferson univeristy, philadelphia, pa, usa, thomas jefferson university, philadelphia, pa, usa, pfizer inc, new york, ny, usa objectives: to identify factors associated with total hospital costs among patients with candidemia in a large, urban, tertiary care, teaching hospital. methods: this retrospective cohort study examined hospitalizations during calendar years and at thomas jefferson university hospital in philadelphia, pa, using data from various hospital systems. candidemia cases were identified via the microbiological laboratory information system as those patients with at least one confirmed positive blood culture for any candida species at any point during the study period. demographic, economic, and clinical data, includ- ing length-of-stay (los), payer types, total costs, and diagnosis related group (drg) assignments were collected from the hos- pital cost accounting system. pharmacy data (i.e. medications administered and associated costs) were retrieved from the phar- macy electronic information system. a multivariate regression analysis, using the natural logarithm of total hospitalization costs as the dependent variable, was conducted. independent variables included demographic information, relative drg weights, and candida species. results: among , total hospitalizations during the study period, cases were con- firmed positive for candidemia. the mean age of cases was years, % were female, and % were caucasian. the mean los was . days and the average inpatient cost for candidemia cases was $ , (sd = $ , ; median, $ , ). the most common candida species was c. albicans (n = ; %). the most commonly used antifungal treatment was fluconazole (n = , %). age, and relative drg weights (p < . ) were significantly positively correlated with total hospital costs. older patients with higher relative drg weights were associated with the higher total costs. race, gender, and marital status were not associated with total costs. conclusion: relative drg weights, as well as age are associated with total hospital costs among patients with candidemia. candidemia is expensive to treat and results in lengthy hospital stay. early detection and treatment may significantly reduce resource use as well as improve outcomes. pin the economic impact of

south korea, korea institute for health and social affairs, seoul, south korea objectives: the objective of this study is to examine the eco- nomic outcome of methicillin resistance in staphylococcus aureus bacteremia in korea, where mrsa is endemic in major- ity of hospitals. methods: we conducted retrospective case- control study of patients admitted to three university-based teaching hospitals in seoul, korea in . cases were defined as patients with methicillin-resistant s. aureus (mrsa) bac- teremia and controls were methicillin- susceptible s. aureus (mssa) bacteremia selected according to a priori matching cri- teria. cases and controls were identified. hospital charges were collected from hospitals’ billing system. results: the median hospital charge after the development of

standard deviation was . . conclusions: these results provide empirical evidence from a very large sample of hospitals that the intensity of pharmaceutical interventions in acute care hospitals in the u.s. exhibits considerable variability. a four-fold difference was detected in intensity score between the lowest intensity hospitals and the highest. this drg-adjusted difference was not due to differences in case-mix across hospitals. further research should be done to determine whether patient outcomes are associated with low versus high pharmaceutical service intensity. mi developing a quality appraisal instrument to evaluate the pediatric health economics literature ungar wj , menon d , lee a , stafinski t the hospital for sick children research institute, toronto, on, canada; institute of health economics, edmonton, ab, canada objectives: the pediatric economic database evaluation (pede) project features a database of pediatric economic evaluations published between and . a goal of the pede project is to appraise the quality of pediatric economic evaluations published over this period. the objective of this research was to develop a valid and reliable quality appraisal instrument applica- ble to economic evaluations in the pediatric population. methods: a draft instrument was constructed from published checklists and questionnaires. new questions pertaining to the pediatric population were incorporated. an expert panel reviewed the draft instrument and the proposed scoring scheme for face and content validity. a revised version was pilot-tested by three independent appraisers. after addressing discrepancies in scores, a final version was created and subjected to inter-rater and test-retest reliability assessment. results: the items in the final questionnaire were mapped onto fourteen domains: economic evaluation, comparators, target population, time horizon, perspec- tive, costs and resource use, outcomes, quality of life, analysis, discounting, incremental analysis, sensitivity analysis, conflict of interest, and conclusions. among the items, have response options that are scored from to . inter-rater reliability was . ( % ci . – . ) and test-retest reliability was . ( % ci . – . ). conclusions: the pediatric quality appraisal ques- tionnaire is a comprehensive instrument demonstrating face and content validity and very good reliability for application in the appraisal of pediatric economic evalu- ations. the instrument is currently being used in a quality appraisal of a random sample of publications from the pede database. health policy—consumer advertising issues hp the relationship of direct-to-consumer advertising and clinician behavioral intentions zachry iii wm, jackson tr the university of arizona, tucson, az, usa objective: to examine the relationship between the exposure of a patient to direct-to-consumer advertising (dtca), and the likelihood of clinician behavioral inten- tions to provide information and medications. methods: a randomized mail survey of arizona primary care physicians (n = ) and physician assistants (n = ) was conducted. questionnaires were created with a hypothetical patient scenario varying according to the informational exposure of the patient ( levels: dtca or drug reference book). all other wording in the hypothetical scenarios was controlled. clinicians were randomly assigned one form of the questionnaire. each form solicited responses to questions related to the likelihood of respondent behavioral intentions ( -point scale, = very likely to = very unlikely) when faced with the hypothetical patient scenario. results: the response rate for useable questionnaires was % ( . % physicians and . % physician assis- tants). no overall statistically significant differences were found between the early responders and late responders. also, no statistically significant differences were found between responders and non-responders based on the metropolitan designations of their practice settings. relative to clinicians who received the “drug reference book” patient scenario, clinicians who received the dtca patient scenario were: more likely to become annoyed with a patient for asking for more information about medications (p = . ); less likely to answer the patient’s questions (p = . ) or provide additional written information (p = . ); more likely to attempt to change the subject rather than discuss an advertised abstracts medication (p = . ); more likely to become frustrated (p = . ) and annoyed (p < . ) with the patient for asking to try a medication; and less likely to provide samples (p = . ) or a prescription (p < . ) for a medication. conclusion: clinicians are amenable to patients asking for drug information and medications, but their level of receptiveness is associated with the source from which the patient’s questions originate. hp relationship of direct-to-consumer advertising spending and drug pricing for the top twenty drugs from to : an exploratory study parthan ag, anantharaman rt, shepherd md the university of texas at austin, austin, tx, usa there exists an ongoing debate regarding the effect of direct-to-consumer (dtc) advertising spending on drug prices. the two opposite views are: (a) increase in dtc advertising spending would be added to drug prices (b) dtc advertising would increase competition and thus reduce drug prices. objective: explore the relationship of dtc advertis- ing spending and drug pricing for the top twenty drugs from to . methods: top twenty drugs were selected on the basis of their dtc advertising spending (source: competitive media reporting, ny) for . for analysis, average wholesale price (awp) per unit was used from the blue book awp unit pricing. for each of the top twenty drugs, the following trend graphs were plotted for to : (a) the total dtc advertising spending and per unit price of the drug; (b) the percent changes in the dtc advertis- ing spending and drug price. the percent change in dtc advertising spending and drug price for a year was calculated as percent change from the previous year. results: only sildenafil (viagra) and sibutramine (meridia) showed an increase in the actual drug price with an increase in the dtc advertising spending. however, for these two drugs in year , the percent change in dtc advertising spending decreased and the percent change in drug price increased. no trend was evident from the graphs of the other eighteen drugs. on an average dtc advertising spending for most of the drugs decreased with time while drug prices continued to increase. conclusion: results indicate a very weak relation- ship between dtc advertising spending and drug prices. the increase in drug price in spite of the decrease in the dtc advertising spending contradicts both rationale i.e. dtc advertising spending reduces drug price through competition or increase in drug price is due to increase in dtc advertising spending. hp impact of direct to consumer advertising—the consumer search for information belazi dt , crawford a , pizzi l thomas jefferson university & abbott laboratories, philadelphia, pa, usa; thomas jefferson university, philadelphia, pa, usa objective: the purpose of this study is to identify factors associated with consumers’ seeking various infor- mation sources about medications sought in response to direct to consumer advertising. methods: in the spring and summer of , the fda, division of drug marketing, advertising, and commu- nication conducted a national telephone survey of adults regarding direct-to-consumer (dtc) promotion of prescription drugs and its effects on visits to the doctor. in addition to consumer attitudes, opinions and responses to direct to consumer advertising, the survey also elicited responses regarding consumer utilization of information sources such as reference books, -telelphone number, and health care providers. there were total respon- dents, of whom completed the required questions regarding information sources. chi square analysis was used to assess associations between consumer demographic information and the different types of informational resources that consumers used after exposure of direct to consumer advertising. results: the analysis showed significant associations (p £ . ) between gender, race, education, health status, self-perceived knowledge of health, prescription medication use, and internet use and many of the following information resources: reference books, asking friends/neighbors, -telephone number, primary doctor, pharmacist, specialist, and nurse. across all information sources, female gender, decreased health status, low education, and higher than average medica- tion use were the variables that had the strongest associ- ations. a model was developed depicting the associations between these findings. results pertaining to specific sources will be presented. conclusions: this study evaluated how different consumers seek information from different sources as a result of direct to consumer advertising. this study will assist those interested in identifying and further educat- ing consumers about their health and novel treatments or therapies. hp fda regulatory actions against misleading or unsubstantiated economic and quality-of-life claims: an analysis of warning letters and notices of

a sunday, february , a receptor x were transfected into cho cells. the cho transfectants were char- acterized by facs and then scaled up for kinexa binding studies. kinexa has been used to measure binding affinity of adnectin-a to the cell surface ex- pressed receptor x to measure the effect of avidity of the multivalent adnectin binding to receptor clusters. as controls for the functional activity of the adnectin-a and the affinity of the monovalent interaction, the same kinexa assay was used, substituting the soluble receptor x extracellular domain for the transfected cho cells. the binding avidity measured by kinexa for cho expressed receptor is pm for both species of receptor x. however, the affinity of adnectin-a for monovalent soluble receptor x was quite different between the species suggesting that avidity due to receptor clustering equilizes the functional avidity at the cell surface. platform: voltage-gated k channels: activation/ inactivation mechanisms -plat a-type kv channel closed-state inactivation is modulated by the tetramerization domain interacting with auxilary kchip a yi-quan tang , fan yang , jingheng zhou , jie zheng , kewei wang . peking university, beijing, china, university of california at davis, davis, ca, usa. a-type kv potassium channels undergo a conformational change towards a non-conductive state at negative membrane potentials, a dynamic process known as closed-state inactivation (csi). csi causes inhibition of channel ac- tivity without prerequisite of channel opening, thus providing a dynamic regu- lation of neuronal excitability, dendritic signal integration and synaptic plasticity. however, the structural determinants underlying kv csi remain largely unknown. we have recently demonstrated that auxiliary kchip a sub- unit contains an n-terminal kv inhibitory domain (kid) that directly interacts with kv . channels to enhance csi. in this study, we utilized the fret two- hybrid mapping and bifc-based screening combined with electrophysiology, and identified the intracellular tetramerization (t ) domain that functions to suppress csi and serves as a receptor for the binding of kid. disrupting kv . t -t interaction by mutating c a within the c h motif of t domain facilitated csi, and ablated the kid-mediated enhancement of csi. furthermore, replacing the characteristic c h motif of kv . t domain with the t domain from kv . without the c h motif or kv . with the c h motif resulted in channels functioning with enhanced or suppressed csi, respectively. taken together, our findings reveal a novel role of the t domain in suppressing kv csi with the c h motif functioning to stabilize the channel activation gate; and kchip a kid directly interacts with the t domain to relieve the stabilization, leading to facilitation of csi and inhibition of channel function. -plat two-in-one: activation and inactivation at the intracellular gate of a kv channel manuel covarrubias , jeffrey d. fineberg . neuroscience, jefferson medical college of thomas jefferson university, philadelphia, pa, usa, physiology and molecular biophysics, jefferson medical college of thomas jefferson university, philadelphia, pa, usa. n-type and p/c-type inactivation are firmly established mechanisms of inac- tivation in voltage-gated kþ (kv channels). however, kv .x channel com- plexes, which undergo fast preferential closed-state inactivation (csi; fineberg et al., , jgp . : - ), appear to use a distinct but un- known inactivation mechanism. previously, we hypothesized that a weak interaction between the voltage sensing domain and the intracellular activa- tion gate underlies csi (bähring & covarrubias, , j physiol : - ). thus, csi is essentially governed by the intracellular activation gate, which fails to open and adopts an inactivated conformation. to directly test this hypothesis, we investigated the heterologously expressed kv . ternary channel complex including accessory subunits kchip and dpp , and ex- ploited the ‘‘trap-door’’ paradigm of the activation gate. the results show that kv . inactivation traps intracellularly applied quaternary ammonium blockers (btbua and tbua) inside the channel’s pore. the trapped blockers can only escape if the channels are opened again by subsequent depolariza- tions. by contrast, inactivation cannot trap tea, whose binding kinetics is faster than that of channel gating. moreover, under identical conditions, a shaker kv channel (shb-t k) known to exhibit fast p/c-type inactivation cannot trap btbua. these findings conclusively suggest that the intracellular activation gate of the kv . ternary channel complex plays a novel dual role, controlling both activation and inactivation. supported in part by nih grant r ns (mc). -plat development and validation studies of universal pharmacophore models for herg channel openers serdar durdagi , , matthew patterson , sergei y. noskov . department of biophysics, bahcesehir university, faculty of medicine, istanbul, turkey, biological sciences, institute for biocomplexity and informatics, university of calgary, calgary, ab, canada. the intra-cavitary drug blockade of herg channel, a common off-target for many drugs, have been extensively studied both experimentally and theoreti- cally. structurally diverse ligands inadvertent blockade of rapid component of delayed rectifying kþ currents are potentially pro-arrhythmic and may lead to drug-induced long qt syndrome-lqts. there are a number of natural strategies for rational drug design; one dubbed the ‘‘passive’’ approach avoids block of herg whereas the ‘‘proactive’’ strategy designs treatments to acti- vate the channel. while ‘‘passive’’ approach has been developed for decades, studies of structural mechanisms of herg channel activation by small mole- cules are truly novel. accordingly, design of the herg openers or current ac- tivators may offer a momentum for modern anti-arrhythmia drug development. significant number of small molecules with capacity for herg activation was identified in mandatory herg screens. to establish possible correlation be- tween activators structure and reactivity, we attempted to construct a universal pharmacophore model for herg channel openers using phase protocol. the biochemical data on kþ channel activators are used in training and test sets. these compounds span a wide range of structurally different chemotypes with ~ ^ -fold variances in binding affinity, which is sufficient for statistically sound model. a developed five sites aahhr (a, hydrogen-bond accepting, h, hydrophobic, r, aromatic) pharmacophore model has showed reasonable high statistical results compared to other constructed models and was selected for steric and electrostatic contour maps analysis. the predictive power of the model was also tested with external test-set (as true unknowns) compounds. pharmacophore model is also combined with previously developed receptor- based homology model of herg k channel and novel activators are generated and screened. the developed ligand-based models may serve as a basis for the synthesis of novel potential therapeutic herg activators. -plat n-terminal regulation of herg kd channel deactivation steven j. thomson, angela hansen, michael c. sanguinetti. nora eccles harrison cardiovascular research and

opposes asynchro- nous early depolarization. inherited point mutations in herg that accelerate deactivation of ikr cause long qt syndrome (lqts), a disorder of ventricular repolarization that increases the risk of lethal cardiac arrhythmia. the intracellular n-terminal domain of herg is known to be essential for slow deactivation. deletion of the entire (~ residues) or just the initial residues of the n-terminus accelerates deactivation -fold. the same effect is achieved by neutralization of the charged residues, arg or arg . how many of the n-termini are required to slow channel deactivation is unknown. herg , like other kv channels, is a homotetramer. by repeatedly linking the c-terminal of one subunit to the n-terminal of the next subunit we constructed concatenated herg tetramers. a variety of homomeric and heteromeric concatenated tetramers were characterized (i.e., wtn/r a:r a( -n); where n = to ). the concatenated channel containing a single r a/r a subunit and wild-type subunits deactivated as fast as the concatenated channel con- taining only r a/r a subunits. the lqts-associated mutation r q, located in the n-terminal of herg was also studied. again, a concatenated tetramer containing a single mutant subunit deactivated as fast as channels with r q mutations in all four subunits. our results show that all n-termini are required to mediate slow deactivation in wild-type herg channels. -plat lipid affinity to the voltage-gated potassium channel kvap elise faure , christine thompson , rikard blunck , . physiology, université de montréal,

"we need more dia- logue with industry;' says who director general, hiroshi nakajima. the who-unicef report, "state of the world's vaccines and immunization;' lauds recent successful campaigns to deliver vac- cines against diseases-including polio, measles, neonatal tetanus, diphtheria, per- tussis, tuberculosis, hepatitis b, and yellow fever-to the world's children, particularly in developing countries. but the report also warns that, "unless the international com- munity continues to back scientific research and global immunization with adequate resources for new vaccines. . .the great promise of molecular biology and genetic engineering may be squandered:' high on the list of global vaccination campaigns are efforts to eradicate polio-a goal that officials expect to meet by the year . in , for instance, nearly half of all children under five, some million, received supplementary doses of polio vac- cines during special national immunization days. but even here, officials are concerned over budget "shortfalls;' mainly from decreased donor funding, that now have the managers of this campaign scrambling for the $ - million needed for vaccine purchases, personnel, training, research, logistics, establishment of a cold chain to preserve vaccine activity, and development of a global laboratory network. the current full allotment of six childhood vaccines (against polio, diphtheria, pertussis, tetanus, measles, and tuberculosis) now costs less than $ for the vaccines-plus $ for program costs. the hepatitis b vaccine has been a touch- stone for the vaccine cost discussion. nakaji- ma points out that the cost of the recombinant hepatitis b vaccine has been dropping, in part because several countries in the developing world, including china, korea, and cuba, now are manufacturing the prod- uct and making it widely available. however, he adds, unless its price falls below $ per dose, this vaccine remains out of reach for much of the world. "we're not saying all vac- cines should be free;' says carol bellamy, executive director of unicef. "we're hoping for a healthy, competitive market and to cre- ate a varied pricing structure." but thomas bombelles, who specializes in international issues for the pharmaceutical research and manufacturers of america association (phrma, washington, dc), argues that innovation can be expensive. "the development costs for vaccines are not all that much lower than for drugs;' he says. "r&d for vaccines is often on the lower end of the range for pharmaceutical products, but it can child receiving an oral polio vaccine in a hospital in phnom penh, cambodia. be from $ - million, which is still an awful lot of money, and there has to be a rea- sonable return on such development costs:' in any case, he says, "the cost is actually very small:' even though its price is higher than that of older vaccine products, its effectiveness makes it a "fantastic bargain" when health outcomes are considered, he says. other improved recombinant vaccine products are nearing regulatory review. for instance, chiron corporation (emeryville, ca) announced in october that it is seeking regulatory clearance for the marketing of pertugen, a diphtheria, tetanus, and geneti- cally engineered acellular pertussis (dtap) vaccine for infants and children. pertugen is the first recombinant dtap vaccine to detox- ify the pertussis toxin. pricing is not the only impediment to wider vaccine development and usage. bombelles notes that adequate safeguards for intellectual property rights are crucial. strengthening of intellectual property laws in china, he says, made it easier for merck (whitehouse station, nj) to share some of its hepatitis b vaccine know-how with chinese collaborators, enabling them to build up domestic vaccine manufacturing capacity. another issue pivots on health-care pri- orities in developing countries. with more than candidate vaccines "in the pipeline," developing countries "need to make resources available at the national level;' points out ciro de quadros, nakaji- ma's special advisor for the who global program for vaccines and immunization. institutions in such countries need to form "consortia to bring vaccine prices down and make sure these products are widely used." jeffrey l. fox edible plant vaccines the first human clinical trial for an edible, plant-based vaccine could start at the beginning of . a team headed by charles arntzen at the boyce thompson institute for plant research (bti, ithaca, ny) is currently undertaking advanced preclinical research on a vaccine for diar- rhea that consists of raw transgenic pota- toes expressing an escherichia coli enterotoxin lt-b subunit gene. if the work goes as planned, the vaccine could enter clinical trials on volunteers at the balti- more vaccine testing center (baltimore, md) in the new year. the potato vaccine, may, however, be beaten to the market by more palatable or technically accessible alternatives. arntzen's research and the similar work of hilary koprowski's group at thomas jef- ferson university (philadelphia, pa) on plants that produce rabies and human immunodeficiency virus antigens are directed at producing edible vaccines for developing countries. "how would you expect [people in] africa or asia to be vacci- nated except by the oral route?" asks koprowski. plants are "the cheapest and the most accessible production method," he says, and they eliminate both the need for refrig- eration, needles, and trained medical staff, and the risks of pathogen-derived vaccines. the bt! potato vaccine has been shown to stimulate the production of specific an tien- terotoxin igg and lga in mice. the next pre- clinical hurdle for the vaccine is to show that it can protect mice against challenge with the e.coli toxin, or with e.coli itself. even though the potato vaccine will be the first plant-based vaccine in human tri - als, it is still rea lly just a model system. few people enjoy raw potatoes (altho ugh charles arntzen did as a ch ild , he told nature biotechnology). according to arntzen's colleague, hugh mason, the first commercial edible plant vaccine will be in bananas. they are much more palatable, nature biotechnology volume november who and unicef find vaccines too costly with surgical bypass, with shorter hospitalizations in symptomatic and asymptomatic patients. further long-term follow-up is required to compare these two treatment modalities for durability to determine the optimal popliteal aneurysm management. multifactorial disease severity score (dss) predicting the success of endovascular intervention of femoropopliteal peripheral arterial disease in-kyong kim, md, natalia egorova, phd, andrew j. meltzer, md, james f. mckinsey, md . columbia university, new york presbyterian hospital system, new york; mount sinai university, new york; and new york presbyterian hospital, new york, ny objective(s): the goal was to create a multifactorial disease severity score (dss) for characterization of femoropopliteal arterial lesions. by having a greater understanding of the effect of patient comorbidities and an in-depth method to characterize an arterial lesion, we may be able to better compare lesions in different studies and predict which therapy is most appropriate for each lesion undergoing an endovascular intervention (evi). methods: we evaluated lesion and patient characteristics in our prospectively maintained lower extremity arterial lesion database from to to create a gradated dss. results: we identified femoropopliteal lesions in patients. statistical analysis by multivariable cox proportional hazards model identi- fied variables that impact patency: seven lesion characteristics (table i) and nine patient characteristics or comorbidities (table ii). factors with the most impact were a chronic total occlusion (dss ), lesion length � mm (dss ), and no runoff vessels and stenosis of % to % (dss ). the following factors were considered baseline, or score of : stenosis � %, lesion length � mm, and three-vessel runoff. by adding these variable scores, a dss was created and used to predict patency of the evi. conclusions: the presence of a chronic total occlusion, lesion length � mm, poor runoff, and the presence of congestive heart failure have the most dramatic effect on patency after evi. a compre- hensive dss allows for the in-depth classification of lesion characteristics and factors that predict success of evi and can allow for comparison of distinct lesions. future comparisons of effectiveness of treatment modal- ities can be possible. table i. significant femoropopliteal lesion characteristics that negatively impact patency after endovascular intervention factor score hr ( % ci) chronic total occlusion .

demonstrated to be a ca þ -sensing protein, which both sets a threshold for low ca þ concentration while it assures cooperative activation during high ca þ rises. mitochondrial ca þ uptake shows tissue specific differences and interestingly, mrna level for micus and mcus also displays tissue specificity. we set out to investigate if the stoichiometry between micu and mcu could account for the previously described differences between heart and liver in mitochondrial ca þ uptake. immunoblotting showed higher expression for all micu , micu and mcu in mouse liver versus heart mitochondria, and a . fold higher micu to mcu ratio in liver. in fluorometric measurements of mitochondrial ca þ uptake, heart mitochondria displayed a decreased threshold and lesser cooperativity compared to liver mitochondria. additionally, nad(p)h elevation was detect- able after exposure to moderate [ca þ ] elevations only in heart mitochondria. overexpression of micu in the heart using aav -micu tail-vein injection significantly increased the micu protein level without any changes of micu or mcu. this increased the micu to mcu ratio in the heart and led to increased thresholding and cooperativity, reproducing the liver-like mito- chondrialca þ uptakephenotype.viceversamicu downregulationintheliver has been shown to lower the threshold and cooperativity of mitochondrial ca þ uptake in hepatocytes. thus, heart and liver mitochondria show different levels of ca þ threshold and cooperative activation of ca þ uptake, which seem to result from differential quantitative relationship between micu and mcu. -pos board b er calcium release is tuned by mitochondrial redox nanodomains david m. booth , balázs enyedi , miklós geiszt , péter várnai , györgy hajnóczky . mitocare center, pathology, thomas jefferson university, philadelphia, pa, usa, department of physiology, semmelweis university, budapest, hungary. spatially and temporally controlled increases of h o emerge as an intracellular signal. we hypothesized that ros and ca þ interact locally, in the restricted vol- ume of the er-mitochondrial interface. these physically tethered structures host enrichments of ion transport proteins such as the ip receptor, which support elevated nanodomains of ca þ during signalling events and are sensitive to h o . we used the genetically encoded h o sensor hyper incorporated into an inducible linker system to probe the redox environment at the er- mitochondrial interface in hepg cells. we found a moderately elevated h o nanodomain which developes into a h o transient following ip receptor- mediated er ca þ release and mitochondrial ca þ uptake. pharmacological in- hibition showed that the transient was dependent upon er ca þ, mitochondrial membrane potential and functional electron transport chain. hyper measure- ments of the mitochondrial intermembrane space revealed significantly elevated h o within this volume. using electron microscopy we found that hepg mito- chondria possess a cohort of dilated cristae, which disappeared following ip - linked ca þ release. paxilline that inhibits mitochondrial bkca channels blocked the cristae reshaping and also abolished the h o transient at the inter- face. furthermore, paxilline caused suppression of the ip -linked calcium signal, whereas interface targeted killer red, a photoactivated h o source, induced sensitization to the ip -linked agonist. we conclude that the intermembrane/ cristae volume of mitochondria represents an oxidized pool fed by the electron transport chain. ca þ -uptake stimulates expansion of the mitochondrial matrix via kþ and concomitant water uptake, squeezing the oxidized volume of the cristae to the interface. here, a transient h o nanodomain sensitizes ip recep- tors to further stimulation. we demonstrate a physiological setting where ca þ release may autoregulate using mitochondrial h o released from the cristae. -pos board b reactive oxygen species (ros) suppress mitochondrial motility valentina debattisti, masao saotome, sudipto das, gyorgy hajnoczky. mitocare center, thomas jefferson university, philadelphia, pa, usa. mitochondrial distribution and transport play pivotal roles for many cellular functions, including cell differentiation, cell division to ensure proper inheri- tance, apoptosis, atp supply at the local sites of demand, ca þ buffering for intracellular ca þ homeostasis. we previously showed that mitochondrial motility (mito-motility) is regulated by the cytosolic ca þ concentration ([ca þ]c), providing the basis for a homeostatic circuit in which the organelles decrease their movements along microtubules to locally buffer high [ca þ ]c and contribute to atp supply. mito- chondria are also a major site for production and scavenging of ros that serve as both a messenger and regulator of calcium signaling and are particularly rele- vant for the control of mitochondrial function. here we tested the hypothesis that ros target mito-motility to control mitochondrial function. h c myoblast cells were transfected with a mitochondrial matrix targeted yfp and then loaded with fura , to monitor the mito-motility simultaneously with [ca þ ]c. h o ( mm) caused a decrease in mito-motility ( %) and an elevation in [ca þ ]c (from to nm) at the same time. when the cells were incu- bated in a ca þ -free medium and were pretreated with thapsigargin to prevent ca þ entry and intracellular ca þ mobilization, respectively, h o continued to inhibit the mito-motility dose-dependently without any changes in [ca þ]c. these results indicate that h o can cause suppression of mito-motility through a ca þ independent mechanism we are currently analyzing. -pos board b miro is dispensable for calcium-mediated inhibition

are bound to the surface of mitochondria and possess ef-hand calcium binding motifs. several groups have reported that miro is involved in mitochondrial motility and inheritance, and particularly its calcium regulation, but the roles of the two isoforms have not been established. genetic deletion of miro in mouse is lethal at birth (nguyen et al., ) and fibroblasts (mefs) derived from miro ko em- bryos show abnormal mitochondrial distribution, but the calcium-dependent in- hibition of motility is unaffected and the respiratory and calcium buffering capacities are normal. neuron-specific knockout of miro leads to progressive deficits of upper motor neuron function, however mitochondria in processes of cortical neurons from miro ko and wild-type embryos showed comparable calcium-sensitive motility inhibition. while no significant increase in miro pro- tein was observed in miro ko mefs, these data raise two possibilities: miro and are interchangeable with regard to calcium regulation of mitochondrial motility or miro is the key player in this regard. to finally resolve this question, we are in the process of generating miro ko and miro / ko cell lines. -pos

fission. to directly evaluate mitochondrial fusion dynamics in cardiomyocytes (cm), mitochondrial matrix-targeted photoactivatable gfp and dsred were intro- duced either in vitro or in vivo by adenovirus and were followed by confocal microscopy. four conditions were analyzed: to h cultured neonatal and in vitro transduced adult cm, and cm from in vivo infected rat hearts. in the latter case, cm were isolated - days after infection and were imaged promptly or - h post harvesting. neonatal cm mitochondria form a highly connected network, whereas both in vitro and in vivo transformed cultured cm displayed only some connectivity. impressively, in vivo transduced adult cm that were imaged promptly after harvesting, unveiled a significantly higher con- nectivity among mitochondria than the - h cultured adult cm. furthermore, fusion events (f.e./ square micrometers/min) were almost absent in cultured in vitro transduced cm, meanwhile in vivo transduced and cultured cm showed . . f.e./min, whereas isolated, freshly-imaged cm displayed . . f.e./min. imaging in perfused whole heart ex vivo, showed consider- able mitochondrial continuity and fusion activity in ventricular cm. to study more directly the role of cm’s contractile activity in mitochondrial fusion, cm were incubated with verapamil ( mm), that blocked spontaneous contrac- tion and partially suppressed the fusion activity of mitochondria. also, mito- chondrial fusion activity appeared to be higher after spontaneous contraction or short term field stimulation in isolated freshly-imaged cm. thus, mitochon- dria are dynamic in both neonatal and adult cm, but under culture conditions, adult cm lose mitochondrial fusion activity. this might be at least in part, because cardiomyocyte contractile activity is altered in culture and contractions likely provide some factors to support mitochondrial fusion activity. -pos board b mechanistic characterization of the thioredoxin system in the removal of hydrogen

bb co-stimulatory domain produced at our institution. expanded bcma-cars were analysed by flow cytometry for markers of t cell dysfunction, or challenged with mm cell line arp- and then tested for cytokine production, cytotoxic ability and activation signals. results bcma-cars cultured in il- or il- /il- expanded similarly to those grown in il- , with comparable car trans- duction efficiencies, cd :cd ratios and proliferation rates. bcma-cars grown in il- had low expression of exhaus- tion marker lag- and high expression of the costimulatory molecule cd , which is important for t cell survival and persistence, when compared to bcma-cars cultured in il- . moreover, bcma-cars grown solely in il- were less dif- ferentiated than those supplemented with il- , and had higher expression of stem cell memory marker cxcr within the naïve population than those expanded with il- . when challenged with mm cell line arp- , il- -grown bcma- cars upregulated activation marker cd , exhibited strong cytotoxicity and robust production of ifng and il- . how- ever, in comparison to bcma-cars expanded in il- or il- /il- , those grown with il- had lower mtorc activity and p mapk phosphorylation when activated by arp- cells, suggesting differential regulation of key pathways for t cell metabolism and senescence, respectively. conclusions to summarise, bcma-cars expanded with il- alone exhibited the most favourable phenotype for therapeutic use compared those grown with il- or il- /il- . future experiments using murine mm models will be critical in understanding the in vivo benefits or drawbacks of culturing bcma-cars in il- compared to il- or il- /il- . ethics approval research involving human material was approved by the ethical committee of clinical research (hos- pital clinic, barcelona). peripheral blood t cells were obtained from healthy donors after informed consent in accordance with the declaration of helsinki. references . roex g, feys t, beguin y, kerre t, poiré x, lewalle p, et al. chimeric antigen receptor-t-cell therapy for b-cell hematological malignancies: an update of the pivotal clinical trial data. pharmaceutics [internet]. ; : – . available from: http://www.ncbi.nlm.nih.gov/pubmed/ . alizadeh d, wong ra, yang x, wang d, pecoraro jr, kuo cf, et al. il enhan- ces car-t cell antitumor activity by reducing mtorc activity and preserving their stem cell memory phenotype. cancer immunol res ; : – . . perez-amill l, suñe g, antoñana-vildosola a, castella m, najjar a, bonet j, et al. preclinical development of a humanized chimeric antigen receptor against b cell maturation antigen for multiple myeloma. haematologica [internet]. ; avail- able from: http://www.ncbi.nlm.nih.gov/pubmed/ http://dx.doi.org/ . /jitc- -sitc . a third-generation human gucy c-targeted car-t cell for colorectal cancer immunotherapy trevor baybutt*, adam snook, scott waldman, jonathan stem, ellen caparosa, alicja zalewski. thomas jefferson university, philadelphia, pa, usa background colorectal cancer (crc) presents a significant public health burden, responsible for the second most cancer- related deaths in the united states, with an increasing inci- dence in young adults observed globally. , while the blockade of immune checkpoints received fda approval as a crc ther- apeutic, only patients with microsatellite instability, accounting for % of sporadic cases, demonstrate partial or complete responses. we present a third-generation chimeric antigen receptor (car)-t cell directed towards the extracellular domain of the mucosal antigen guanylyl cyclase c (gucy c), which is over-expressed in % of crc cases, as a therapeu- tic alternative for late stage disease. here, we demonstrate that human gucy c car-t cells can selectively kill gucy c-expressing colorectal cancer cells in vitro and pro- duce inflammatory cytokines in response to antigenic stimulation. methods peripheral blood mononuclear (pbmcs) cells were isolated from leukoreduction filters obtained from the thomas jefferson university hospital blood donor center (irb # d. ). magnetic activated cell sorting (macs) technol- ogy was used to negatively select pan-t cells (miltenyi biotec), followed by activation and expansion using anti-cd , anti- cd , and anti-cd coated microbeads (miltenyi biotec) and supplemented with il- and il- (biological resources abstracts j immunother cancer ; (suppl ):a –a a o n a p ril , b y g u e st. p ro te cte d b y co p yrig h t. h ttp ://jitc.b m j.co m / j im m u n o th e r c a n ce r: first p u b lish e d a s . /jitc- -s it c . o n d e ce m b e r . d o w n lo a d e d fro m http://jitc.bmj.com/ branch preclinical biologics repository – nci). t-cells were transduced with a lentiviral vector encoding the anti-gucy c car. our car utilizes a single chain variable fragment of human origin directed towards the extracellular domain of gucy c, the cd hinge, transmembrane, and intracellular signaling domain (icd), - bb (cd ) icd, and cd z icd. car-t cells were used for experiments between to days after activation in vitro using the xcelligence real time cytotoxicity assay and intracellular cytokine staining. results gucy c-directed car-t cells specifically lysed the gucy c-expressing metastatic crc cell line t , while the control car did not. gucy c-negative crc cells were not killed by either. in addition to cell killing, gucy c-directed car-t cells of both the cd + and cd + co-receptor lineage produced the inflammatory cytokines ifn-g and tnfa in response to gucy c antigen. conclusions we demonstrate that human gucy c-directed car-t cells can selectively target gucy c-expressing cancer cells. we hypothesize that gucy c-directed car-t cells present a viable therapeutic option for metastatic crc. in vivo animal models to examine this potential are currently on- going. acknowledgements this work was supported by the depart- ment of defense congressionally directed medical research programs (w xwh- -
