The molecular cloning of new neuroactive growth factors and their receptors has greatly enhanced our understanding of important interactions among receptors and singnaling molecules. These studies have begun to illuminate some of the mechanisms that allow for specificity in neuronal signaling. Model cell systems, such as the PC‐12 pheochromocytoma cell line, express receptors for these different neurotirophic factors, leading to comparisons of signaling pathways for these factors. Upon binding their ligands, these receptors undergo phosphorylation on tyrosine residues, which directs their (...) interaction with signaling proteins containing src homology (SH2) domains, sequences that mediate associations with tyrosine‐phosphorylated proteins. These SH2 proteins translate the tyrosine kinase activity of receptors into downstream events that result in the specific cellular response. Investigations such as these have revealed that molecular specificity in signaling pathways may arise from combinatorial diversity in interactions between receptors and key regulatory proteins.

Since the Harvard Committees bold and highly successful attempt to redefine death in 1968 (Harvard Ad Hoc committee, 1968), multiple controversies have arisen. Stimulated by several factors, including the inherent conceptual weakness of the Harvard Committees proposal, accumulated clinical experience, and the incessant push to expand the pool of potential organ donors, the lively debate about the definition of death has, for the most part, been confined to a relatively small group of academics who have created a large body of (...) literature of which this issue of the Journal of Medicine and Philosophy is an example. Law and public policy, however, have remained essentially unaffected. This paper will briefly review the multiple controversies about defining death in an attempt to explain why they have and will remain unresolved in the academic community and have even less chance of being understood and resolved by politicians, legislators, and the general public. Considering this, we will end by suggesting the probable course of public policy and clinical practice in the decades ahead. (shrink)

This book is the first comprehensive report and analysis of the Dutch euthanasia experience over the last three decades. In contrast to most books about euthanasia, which are written by authors from countries where the practice is illegal and therefore practised only secretly, this book analyzes empirical data and real-life clinical behavior. Its essays were written by the leading Dutch scholars and clinicians who shaped euthanasia policy and who have studied, evaluated and helped regulate it. Some of them have themselves (...) practised euthanasia. The book will contribute to the world literature on physician-assisted death by providing a comprehensive examination of how euthanasia has been practised and how it has evolved in one specific national and cultural context. It will greatly advance the understanding of euthanasia among both advocates and opponents of the practice. (shrink)

One way of increasing the supply of vital organs without violating the dead donor rule is to declare death on cardiopulmonary criteria after withdrawing life support. The question then is how quickly death may be declared.

ABSTRACT Written in late March 2020 in the early days of the U.S. coronavirus outbreak, this essay represents a contingent reflection on the American pandemic response, mourning in anticipation of what would soon surely unfold. I argue that the State's long-standing sacrificial economies have in this moment culminated in a suicidal State. The term is Foucault's, appearing in a controversial lecture on biopolitics, Nazism, and “biological racism.” Despite Foucault's problematic treatment of racism, I suggest that some aspects of this discourse (...) might nevertheless be apropos in our context. The U.S. pandemic response is racism's suicidal State legacy writ large: an extension and retooling of historically racist infrastructures deployed in racialized domains, but in this moment also across biosocial inequities and vulnerabilities marked by differential fungibilities other than race.

Invertebrate genetic models with their tractable neuromuscular systems are effective vehicles for the study of human nerve and muscle disorders. This is exemplified by insights made into spinal muscular atrophy (SMA) using the fruit fly Drosophila melanogaster and the nematode worm Caenorhabditis elegans. For speed and economy, these invertebrates offer convenient, whole‐organism platforms for genetic screening as well as RNA interference (RNAi) and chemical library screens, permitting the rapid testing of hypotheses related to disease mechanisms and the exploration of new (...) therapeutic routes and drug candidates. Here, we discuss recent developments encompassing synaptic physiology, RNA processing, and screening of compound and genome‐scale RNAi libraries, showcasing the importance of invertebrate SMA models.Editor's suggested further reading in BioEssays: SMN and Gemins: ‘We are family’... or are we?

Working within the tradition of continental philosophy, this article argues in favour of a phenomenological understanding of language as a crucial component of bioethical inquiry. The authors challenge the ‘commonsense’ view of language, in which thinking appears as prior to speaking, and speech the straightforward vehicle of pre-existing thoughts. Drawing on Maurice Merleau-Ponty's (1908–1961) phenomenology of language, the authors claim that thinking takes place in and through the spoken word, in and through embodied language. This view resituates bioethics as a (...) matter of bodies that speak. It also refigures the meaning of ethical self-reflexion, and in so doing offers an alternative view on reflexivity and critique. Referring to the Kantian critical tradition and its reception by Hannah Arendt and Michel Foucault, we advance a position we call ‘critical ethical reflexivity’. We contend that Merleau-Ponty's phenomenology of language offers valuable insight into ethical reflexivity and subject formation. Moreover, his understanding of language may foster new qualitative empirical research in bioethics, lead to more nuanced methods for interpreting personal narratives, and promote critical self-reflexion as necessary for bioethical inquiry.

This article recounts the evolution of a global debate on the development of a common international code of journalistic ethics that would apply to East and West, Developed and Developing Countries. It sees as unlikely universal principles and prescriptions for professionals can be adopted across the divergent sociopolitical philosophies involved. Even common ground for constructive discussion on the topic is limited. Scholars, journalists, and educators are encouraged to instill an appreciation for the differences and to help create an understanding of (...) the special problems involved in media relationships among countries.

Over the past decade, public discussion has focused on the ethics of issuing Do‐Not‐Resuscitate Orders, and the failure of many hospitals to acknowledge their actions openly. Recent efforts on the part of some hospitals to establish formal DNR guidelines that are prudent, fair, and humane, are a helpful beginning, though they cannot account for all the vagaries of illness and human communication. But concerns about DNR should not divert us from looking closely and rigorously at other, more common treatment/nontreatment decisions (...) in the critical care setting. (shrink)

This essay reads J.M. Coetzee’s novel, Diary of a Bad Year, as an occasion to problematize contemporary bioethical paradigms. Coetzee’s rhetorical strategies are analyzed to better understand the “scene of address” within which ethical claims can be voiced. Drawing on Foucault’s Socratic understanding of ethics as the self’s relation to itself, self-relation is explored through the rhetorical figure of catachresis. The essay ultimately argues that the ethical voice emerges when the terms—terms by which I relate to myself, to others, to (...) my own body, and to the bodies of others—are themselves subject to catachrestic refiguration.

This paper explores a novel philosophy of ethical care in the face of burgeoning biomedical technologies. I respond to a serious challenge facing traditional bioethics with its roots in analytic philosophy. The hallmarks of these traditional approaches are reason and autonomy, founded on a belief in the liberal humanist subject. In recent years, however, there have been mounting challenges to this view of human subjectivity, emerging from poststructuralist critiques, such as Michel Foucault's, but increasingly also as a result of advances (...) in biotechnology itself. In the face of these developments, I argue that the theoretical relevance and practical application of mainstream bioethics is increasingly under strain. Traditionalists will undoubtedly resist. Together, professional philosopher-bioethicists, public health policymakers, and the global commercial healthcare industry tend to respond conservatively by shoring up the liberal humanist subject as the foundation for medical ethics and consumer decision-making, appealing to the familiar tropes of reason, autonomy, and freedom.

Each is for the other the middle term, through which each mediates itself with itself and unites with itself; and each is for itself, and for the other, an immediate being on its own account, which at the same time is such only through this mediation. They recognize themselves as mutually recognizing one another. Scholars seeking an account of recognition will be familiar with the seminal section on lordship and bondage in Hegel’s Phenomenology of Spirit. In these passages we learn (...) that the dialectic of mutual recognition is the key to actualized self-consciousness, that moment in which the “I” transcends its immanence in the life process to become a self-reflective subject, actively superseding the..

In lieu of an abstract, here is a brief excerpt of the content:IntroductionStuart J. Youngner (bio), Laura A. Siminoff (bio), and Renie Schapiro (bio)This issue of the Kennedy Institute of Ethics Journal (KIEJ) centers on a piece of empirical research. The motivation behind the study of Laura Siminoff, Christopher Burant, and Stuart Youngner (2004) was to find out more about what the general public understands and believes about when a person is dead. More specifically, the study tried to determine (...) how members of the public define death, especially their acceptance and interpretation of the medical concept of "brain death," and their attitudes toward the so-called "dead donor rule," an informal but powerful social and legal norm insisting that the taking of organs for transplantation not cause the death of the source of those organs.As the demand for organs increases and the waiting list grows, the United States has explored multiple ways to expand the pool of potential donors. One approach has been to gerrymander (coherently or not) the line between life and death to shift patients who are extremely compromised but traditionally considered to be in the living category into the dead category. In this way, the dead donor rule remains technically intact. This reasoning is explicit in the report of the Harvard Medical School Ad Hoc Committee (1968) that "introduced" "brain death" to the American culture. Since then, other efforts to redraw the line have been proposed and rejected.One alternative to gerrymandering is to consider under what conditions, if any, it is morally acceptable to violate the dead donor rule. Some would argue that this alternative is the more "honest" approach. Rather than sidestepping moral problems by calling people dead, it brings the moral problems to the surface where the necessity of sticking to the rule can be considered on its own merits. However, when the Journal of the American Medical Association printed a position paper that proposed making anencepahlic newborns an exception to the dead donor rule, along with arguments about why this was acceptable, the outcry was so great that the proposal was retracted (AMA 1995).Clearly, our society has identified organ transplantation as a priority, although two papers in this volume (those by Courtney Campbell and by Megan Crowley-Matoka and Robert Arnold) take issue with that prioritization. The fact that the donor pool has remained relatively stable (and inadequate) despite massive efforts [End Page 211] to increase it speaks, at least in part, to the cultural and legal resistance to "new" ways to procure more organs. Voluntarism seems to have peaked. Financial incentives clash with the heavily endorsed notion of the "gift of life" and seem to many to violate the dignity of the human body. Presumed consent or eminent domain, in which the community has a greater claim to a person's organs than that person or his/her family, go against the grain of American individual freedom and the ethos of patient autonomy.Abandoning the dead donor rule generally is regarded as an even tougher sell to the American public and its legislators. The study by Siminoff and colleagues attempts, among other things, to gauge just how tough this sell would be. What the data actually demonstrate is a matter of interpretation, and this issue of the KIEJ is devoted to some of those interpretations. The authors, with the exception of Daniel Hausman, came together for a meeting in Cleveland, Ohio, during which the study's methods and data were presented with time for questions, clarifications, and general discussion. The authors then worked with the editors to generate the papers printed in this volume.The issue begins with a presentation of the study conducted by Siminoff and colleagues. The same paper also appears in the journal Social Science and Medicine, where it includes the conclusions of the authors (Siminoff, Burant, and Youngner 2004). In the current volume, we present only the methodology of and data from the study, allowing a number of distinguished commentators to offer their own conclusions and reflections.The first response comes from Tracy Schmidt, Executive Director of Intermountain Donor Services, one of our nation's organ procurement organizations (OPOs). For years, organ procurement professionals have reported anecdotal stories about families who wished to donate organs of... (shrink)
