Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

In financial disputes involving research, the parties are traditionally individual researchers and their institutions, biotech and pharmaceutical companies, and other entities engaged in the commercial development of biomedical research. Occasionally, research subjects claim that researchers have misled them or misappropriated their biological materials to derive financial gain. The best known example is the case of Moore v. Regents of the University of California, decided in 1990.With new developments in genomics, large-scale repositories of tissue and other biological specimens are increasingly important. (...) Biobanks have been established by various researchers, commercial entities, health-care institutions, and even entire countries. Individuals who contribute specimens almost always retain no commercial interest in any resulting research and language to that effect is now customarily included in informed consent documents signed at the time the specimen is given. Suppose, however, that the research subjects actually collect the specimens themselves, recruit the researcher, and provide financial support for the research. (shrink)

The old proverb can still more accurately be applied to their biographers.‘ Even the more plausible and psycho logically tempting details in the lives of literary figures derive from these authors’ fictional works, poems, and dramas, and not from the kind of source material biographers use today, letters, documents, eyewitness testimony. Critics and readers eager to establish some historical correlation between any ancient poet's life and his work should expect to be disappointed. But even if the ancient lives are useless (...) to the historian or critic trying to explain what in Euripides’ experience compelled him to write about Medea, these stories are of interest to mythologists. If we stop being angry at the Lives for failing to be historical, and look at them rather as myths or fairy tales, some informative patterns begin to emerge. (shrink)

In the surviving plays of Aeschylus and Sophocles the gods appear to men only rarely. In the Eumenides Apollo and Athena intervene to bring acquittal to Orestes. In Sophocles' Philoctetes Heracles appears ex machina to ensure that the hero returns to Troy, and we learn from a messenger how the gods have summoned the aged Oedipus to a hero's tomb. In Sophocles' Ajax Athena drives Ajax mad and taunts him cruelly. Prometheus Bound might seem to be an exception, since all (...) but one of its characters are gods. But nonetheless the intervention of the gods in the life of the one human character, Io, brings pain and trouble as well as promise of benefit. Io has been driven mad because she has refused to obey the dreams that tell her to go to the meadow where Zeus wants to have intercourse with her. The god does not make his request in person, and it is only in the course of her wanderings that Io learns how Zeus will bring a gentle end to her sufferings. Her informant is another god, Zeus' adversary Prometheus, who answers her questions, at times grudgingly , and in ways that are not immediately clear to her. (shrink)

This article focuses on two possible missions for a national bioethics commission. The first is handling differences of worldview, political orientation, and discipline. Recent work in political philosophy emphasizes regard for the dignity of difference manifested in "conversation" that seeks understanding rather than agreement. The President's Council on Bioethics gets a mixed review in this area. The second is experimenting with prophetic bioethics. "Prophetic bioethics" is a term coined by Daniel Callahan to describe an alternative to compromise-seeking "regulatory bioethics." It (...) involves a critique of modern medicine. In the contemporary context, the areas of biotechnology and access to health care cry out for prophetic attention. The Council has addressed biotechnology; unfortunately, that experience suggests that the kind of prophecy that it practices poses risks to conversation. With regard to access issues, the article proposes an effort that unites themes of human dignity, solidarity, and limits in support of reform, while highlighting, rather than papering over, differences.

Clinical experience suggests that adult survivors of childhood trauma arrive at their memories in a number of ways, with varying degrees of associated distress and uncertainty and, in some cases, after memory lapses of varying duration and extent. Among those patients who enter psychotherapy as a result of early abuse, three general patterns of traumatic recall are identified: relatively continuous and complete recall of childhood abuse experiences coupled with changing interpretations of these experiences, partial amnesia for abuse events, accompanied by (...) a mixture of delayed recall and delayed understanding, and delayed recall following a period of profound and pervasive amnesia. These patterns are represented by three composite clinical vignettes. Variations among them suggest that the phenomena underlying traumatic recall are continuous not dichotomous. Future research into the nature of traumatic memory should be informed by clinical observation. (shrink)

Pressure is mounting to hold researchers and research institutions accountable for the protection of human subjects. When subjects or their family members believe they have been injured, they are increasingly willing to file lawsuits. Recent cases indicate that institutional review boards and their members may be pulled more and more into the legal fray.On September 17, 1999, 18-year-old Jesse Gelsinger died while participating in research conducted by the University of Pennsylvania's Institute for Gene Therapy. Gelsinger was involved in a Phase (...) I clinical trial testing a new approach to treatment of ornithine transcarbamylase deficiency, a rare metabolic disorder. Although infants affected by the severe form of OTC die shortly after birth, Gelsinger suffered from a relatively mild form. It appears undisputed that the cause of Gelsinger's death was not the disorder itself, but multiple organ system failure triggered by the virus used to carry new genetic material into his system.

Although authorship policies exist, researchers understand little about their impact on perceptions of authorship scenarios. Graduate students (N = 277) at a large university read 1 of 3 vignettes about a graduate student-faculty collaboration. One half of the surveys included the American Psychological Association's statement on authorship. Participants rated (a) the ethics of the professor as first author and (b) the likelihood of a dissatisfied student reporting the authorship result, as well as the effectiveness and negative consequences of reporting. Work (...) arrangements on the project had a consistent main effect. Also, an authorship policy impacted women's ratings of first authorship when the student contributed the idea for a project. For men, a policy impacted only ratings of the likelihood of reporting when a professor was first author on a student's dissertation. Apart from sex, no other demographic variables on participants were predictive. Discussion focuses on the policy's potential for making only some specific issues salient. (shrink)

Prior studies have shown a general preference among citizens for juries over judges. Researchers, however, have not considered whether race and ethnicity modify this preference. We hypothesized that minorities (African-Americans, Hispanics), who generally express less trust in the legal system, may also express less trust in juries than non-Hispanic whites. We asked a representative sample of 1,465 residents of Texas to state whether they would prefer a jury or a judge to be the decision maker in four hypothetical circumstances. Consistent (...) with expectations, non-Hispanic whites favored juries over judges, particularly if they imagined themselves as a defendant in a criminal trial. By comparison, although African-Americans and some Hispanics generally favored juries, they showed a much weaker set of jury preferences. African Americans had markedly lower support for the civil jury, but support was higher among minorities with prior jury service. Among Hispanics, respondents who took the survey in Spanish typically preferred a judge to make legal decisions. We consider the implications of our findings for trust in the jury system and trust in community members as decision makers. (shrink)

Water famine. -- The only possibility. -- The three gift, author.

From certain sorts of premise, individuals reliably infer invalid conclusions. Two Experiments investigated a possible cause for these illusory inference: Reasoners fail to think about what is false. In Experiment 1, 24 undergraduates drew illusory and control inferences from premises based on exclusive disjunctions (“or else”). In one block, participants were instructed to falsify the premises of each illusory and control inference before making the inference. In the other block, participants did not receive these instructions. There were more correct answers (...) for illusory disjunctions whose premises had been falsified than there were for illusory disjunctions that had not been falsified. A second Experiment introduced illusory inferences in a real world context that accentuated falsification of premises. Accuracy also improved. Knowledge of how to falsify premises and to consider their implications for true premises transferred to a new problem introduced at the end of the Experiment without the falsification instruction. The participants' ratings of the difficulty of the inferences showed that they did not err simply because illusory inferences are perceived to be more difficult than control problems. The model theory predicts these results because it postulates that the limitations of working memory preclude the representation of false information. (shrink)
