This academic paper on Ethical issues of using umbilical cord blood stem cell therapy of John Stuart Mill perspective aim to investigate the new approaches in the treatment of diseases by using umbilical cord blood stem cells. And also to study ethical issues from the use of umbilical cord blood stem cells in the treatment of diseases considered by Mill’s utilitarianism. 21st century, the medical industry was interested in organ transplantation from (...) stem cells especially stem cells from the umbilical cord to treat chronic and degenerative organ diseases, blood cancer and organ transplantation which successful and widespread throughout the world. Thailand has about 900 new children with Leukemia every year. About 50 percent are leukemia which needs to be treated correctly and urgently. In general Standardized chemotherapy but if the cancer patient has a bad prognosis Or have recurrent cancer Patients need to be treated with bone marrow transplants or stem cells to have a chance to heal. According to Mill’s Utilitarianism, the ethical concepts that determine what is the basic criterion used to determine whether it should or should not concern with the popular benefit that the criterion used is the amount of happiness that results from actions. Treating the disease using stem cells will make the patient recover from the disease, healthier and happier in life. As Mill said "The correctness of an action depends on the tendency that the action will lead to happiness. (shrink)

BackgroundThe Act Regarding the Promotion of the Appropriate Supply of Hematopoietic Stem Cells for Transplant regulates only how public banks store and provide umbilical cord blood for research or transplantation. Japan had no laws to regulate how the private banks manage the procedures, harvesting, preparation, and storage of such blood. As a result, the status of UCB distribution remains unknown. We conducted a survey to investigate the current status of UCB storage and provision to private biobanks (...) by Japanese institutions that handle childbirth.MethodsQuestionnaire forms were mailed to 3,277 facilities handling childbirth that were registered in the Japan Council for Quality Health Care website.ResultsOf the 1,192 institutions handling childbirth that participated in the survey, 34.4% responded that they currently provide UCB to private biobanks, while 16.1% of facilities did so in the past. Moreover, some institutions currently provide or formerly provided UCB to medical treatment facilities, research institutions, companies, or overseas treatment facilities, research institutions, or companies. A certain number of institutions handling childbirth did not even provide explanations or obtain consent when the UCB was harvested from private bank users.ConclusionsThis is the first study to determine the status of UCB provision to private banks by Japanese institutions handling childbirth. Future studies will need to examine in detail how institutions handling childbirth provide explanations to private bank users and UCB providers as well as how these institutions obtain consent.

Critical examination of the concept of property in the body, with particular relevance to Stephen Munzer's work on umbilical cord blood.

How are we individually and as a society to handle new and emerging technologies? This challenging question underlies much of the bioethical debates of modern times. To address this question we need suitable conceptions of the new technology and ways of identifying its proper management and regulation. To establish conceptions and to find ways to handle emerging technologies we tend to use analogies extensively. The aim of this article is to investigate the role that analogies play or may play in (...) the processes of understanding and managing new technology. More precisely we aim to unveil the role of analogies as analytical devices in exploring the "being" of the new technology as well the normative function of analogies in conceptualizing the characteristics and applications of new technology. Umbilical cord blood biobanking will be used as a case to investigate these roles and functions. (shrink)

BackgroundPrivate umbilical cord blood banking is a for-profit industry in which parents pay to store blood for potential future use. Governments have noted the tendency for private banks to oversell the potential for cord blood use, especially in relation to speculative cell therapies not yet supported by clinical evidence. We assessed the regulatory landscape governing private cord bank marketing in Canada.Main bodyBecause the problematic marketing of private cord blood banking for future (...) use often relates to speculative future cell therapies that do not exist and are not being advertised for current clinical use, most private blood bank marketing seems to fall outside Health Canada’s regulatory scope. However, this problematic marketing is regulated by the Competition Bureau pursuant to the Competition Act. While representations relating to future hypothetical treatments may not always be subject to the legal requirement for claim substantiation, the law also prohibits individuals and companies from knowingly or recklessly making representations that are “false or misleading in a material respect.” A representation is materially false or misleading when it could “influence a consumer’s behavior or purchasing decisions,” and consumers are likely to be considered to be “credulous and inexperienced” for the purposes of assessing an advertisement’s general impression. Because all of the potential benefit of the banking is derived from the potential future use of the biological material for health interventions directed toward the customers and their relatives, and because we know the best available medical evidence indicates a very low probability of utility in this context, we can say with confidence that some private cord blood banking claims are materially misleading. Moreover, to the extent that medical professionals are involved in private bank interactions with customers or hold ownership stakes in private banks, they are subject to professional codes, standards of practice, and potentially fiduciary obligations that further prohibit misleading marketing.ConclusionsPrivate cord blood bank marketing that advertises hypothetical future treatments can be misleading and may influence consumer behaviour. This marketing may breach existing advertising law. Regulatory bodies should enforce the law in order to help prevent public health and personal financial harm. (shrink)

BackgroundUmbilical cord banks are a central component, as umbilical cord tissue providers, in both medical treatment and scientific research with stem cells. But, whereas the creation of umbilical cord banks is seen as successful practice, it is perceived as a risky style of play by others. This article examines and discusses the ethical, medical and legal considerations that arise from the operation of umbilical cord banks in Mexico.DiscussionA number of experts have stated that (...) the use of umbilical cord goes beyond the mere utilization of human tissues for the purpose of treatment. This tissue is also used in research studies: genetic studies, studies to evaluate the effectiveness of new antibiotics, studies to identify new proteins, etc. Meanwhile, others claim that the law and other norms for the functioning of cord banks are not consistent and are poorly defined. Some of these critics point out that the confidentiality of donor information is handled differently in different places. The fact that private cord banks offer their services as "biological insurance" in order to obtain informed consent by promising the parents that the tissue that will be stored insures the health of their child in the future raises the issue of whether the consent is freely given or given under coercion. Another consideration that must be made in relation to privately owned cord banks has to do with the ownership of the stored umbilical cord.SummaryConflicts between moral principles and economic interests (non-moral principles) cause dilemmas in the clinical practice of umbilical cord blood storage and use especially in privately owned banks. This article presents a reflection and some of the guidelines that must be followed by umbilical cord banks in order to deal with these conflicts. This reflection is based on the fundamental notions of ethics and public health and seeks to be a contribution towards the improvement of umbilical cord banks' performance. (shrink)

Private cord blood banking is the practice of paying to save cord blood for potential future use. Informed by the literature on corporeal commodification and feminist theories, this article analyses women’s work in banking cord blood. This article is based on in-depth interviews with 13 women who banked in a private bank in Canada. From learning about cord blood banking to collecting cord blood and transporting it to the private bank’s (...) laboratory, women labour to ensure that cord blood is successfully banked. Private cord blood banking involves the overlap or insertion of commercial practices, and relations with clinical practices and relations that may cause tensions and confusion for women and clinical practitioners. Moreover, private banking reinforces and is reinforced by an ‘intensive mothering’ ideology. This article shows that corporeal commodification is not confined to a laboratory and the work of experts but extends into women’s everyday lives. (shrink)

Over the past decade, umbilical cord blood (UCB) has routinely been used as a source of haematopoietic stem cells for allogeneic stem cell transplants in the treatment of a range of malignant and non-malignant conditions affecting children and adults. UCB banks are a necessary part of the UCB transplant program, but their establishment has raised a number of important scientific, ethical and political issues. This paper examines the scientific and clinical evidence that has provided the basis for (...) the establishment of UCB banks. We also discuss the major ethical issues that UCB banks raise, including ownership of cord blood, processes for obtaining consent for its collection and storage, and confidentiality. Finally, we review other concerns about commercial non-altruistic banking, including concerns about social justice, equity of access and equity of care. (shrink)

Umbilical cord blood has become the focus of intense efforts to collect, screen and bank haematopoietic stem cells in hundreds of repositories around the world. UCB banking has developed through a broad spectrum of overlapping banking practices, sectors and institutional forms. Superficially at least, these sectors have been widely distinguished in bioethical and policy literature between notions of the ‘public’ and the ‘private’, the commons and the market respectively. Our purpose in this paper is to reflect more (...) critically on these distinctions and to articulate the complex practical and hybrid nature of cord blood as a ‘bio-object’ that straddles binary conceptions of the blood economies. The paper draws upon Roberto Esposito’s reflections on biopolitics and his attempt to transcend the dualistic polarisations of immunity and community, or the private and the public. We suggest that his thoughts on immunitary hospitality resonate with many of the actual features and realpolitik of a necessarily internationalised and globally distributed UCB ‘immunitary regime’.

More impetus needs to be placed on cord blood donationIn July, the Royal College of Obstetricians and Gynaecologists released a report on the uses and the potential perils of umbilical cord blood collection.1 This report has had the positive effect of drawing attention to what has hitherto been an under addressed topic of medical research and ethics. However, the focus and recommendations of the report say little about one important aspect of cord blood (...) usage—research. Such an omission, although understandable from an organisation primarily concerned with maternal and neonatal health, may nevertheless have implications for the broader applicability of the report’s recommendations, outside the immediate arena of patient care.The RCOG report deals with various aspects of cord blood collection and use—the harvesting procedure itself; cord blood transplantation treatment, either as an autologous cell transplant or as a donation for community use; and whether cord blood banking for personal use should be permitted or encouraged as a privately funded commercial enterprise. It also makes note of some of the legal and ethical issues surrounding cord blood and tissue banking more generally, concerns that will be of increasing importance as more biobanks are established worldwide. A large part of the report deals with concerns on neonatal and maternal safety and whether cord blood collection may pose a risk. These concerns may be valid and certainly, the health of mothers and children should not be compromised. The guidance provided by this report in relation to the collection procedure will undoubtedly assist maternity health professionals in this area.The main relevance of the RCOG …. (shrink)

One of the most intriguing bio-objects in the emerging field of regenerative medicine is umbilical cord blood. Employed in existing haematological therapies, but also loaded with potentialities for future uses, cord blood has been lately the focus of a regulatory debate which confronts public and private forms of biobanking. This article explores the political and anthropological side of this debate, describing the ways in which different health practices related to the umbilical cord (and (...) to its symbolic sibling, the placenta) have been involved in processes of societal production and reproduction. Through the use of ethnological and historical data, and their comparison with current practices, I contend that the technical manipulation of cords and placentas goes much longer into the past than what a first glance suggests, and that these two objects can be understood as biological spaces in which forms of social belonging and versions of the societal bond are at play. The current conflict between public and private cord blood banks is therefore interpreted as part of a longer history of bodily practices, and as reflecting recent mutations in the biopolitical constitution of advanced liberal societies.

This paper explores the perspectives of women who have agreed that their umbilical cord blood may be collected for a public ‘cord blood bank’, for use in transplant medicine or research. Drawing on interview data from 27 mothers who agreed to the collection and use of their umbilical cord blood, these choices and the informed consent process are explored. It is shown that the needs of sick children requiring transplants are prominent in (...) narrative accounts of cord blood banking, together with high expectations for future applications of stem cells. Given this dynamic, a concern arises that the complex and multiple uses of tissues and related data might be oversimplified in the consent process. In conclusion, the positive finding of a commitment to mutuality in cord blood banking among these women is underlined, and its implications for the wider debate on cord blood banking are discussed.

Robust ex vivo expansion of umbilical cord blood (UCB) derived hematopoietic stem and progenitor cells (HSPCs) should enable the widespread use of UCB as a source of cells to treat hematologic and immune diseases. Novel approaches for HSPC expansion have recently been developed, setting the stage for the production of blood stem cell derived products that fulfill our current best known criteria of clinical relevance. Translating these technologies into clinical use requires bioengineering strategies to overcome challenges (...) of scale‐up, reproducibility, and product quality assurance. Clinical‐scale implementation should also define criteria and targets for cost‐effective cell manufacturing. As production strategies become more effective, new opportunities in the therapeutic use of ex vivo expanded hematopoietic cell products will emerge. Herein we examine key technological milestones that need to be met in order to move ex vivo expanded HSPC therapies from the bench‐top to the bedside in a robust and reliable manner. (shrink)

Umbilical cord blood banking is one of many biomedical innovations that confront pregnant women with new choices about what they should do to secure their own and their child’s best interests. Many mothers can now choose to donate their baby’s umbilical cord blood (UCB) to a public cord blood bank or pay to store it in a private cord blood bank. Donation to a public bank is widely regarded as an (...) altruistic act of civic responsibility. Paying to store UCB may be regarded as a “unique opportunity” to provide “insurance” for the child’s future. This paper reports findings from a survey of Australian women that investigated the decision to either donate or store UCB. We conclude that mothers are faced with competing discourses that force them to choose between being a “good mother” and fulfilling their role as a “good citizen.” We discuss this finding with reference to the concept of value pluralism.

'An alarming and illuminating book. The story of how we have allowed private corporations to patent genes, to stockpile human tissue, and in short to make profits out of what many people feel ought to be common goods is a shocking one. No one with any interest at all in medicine and society and how they interact should miss this book, and it should be required reading for every medical student,'--Philip Pullman.

Definition of the problem: Stem cell transplantations from umbilical cord blood, especially if from autologous origin, are often treated with distrust. Not only are the therapeutic effects controversial, but the question of ownership is also hard to answer from an ethical point of view. Furthermore, the extraction of umbilical cord blood is already related to information about the factual and potential health condition of the child and its parents. Arguments and conclusion: The three problems (...) will be discussed separately. Despite certain uncertainties, there are no weighty ethical arguments against the extraction of umbilical cord blood for autologous purposes. The owner of the umbilical cord blood should be the mother. The question of information is not at all typical for this problem area and does not carry more weight here than in other relevant medical situations. (shrink)

Experiments have suggested that umbilical cord blood stem cells can be used to prevent diseases such as atherosclerosis. This paper discusses ethical issues surrounding such usage such as the uncertainty that individuals at risk of a disease will actually get the disease; issues related to research with children; safety issues; from where these stem cells would be obtained; and whether these usages should be considered as therapies or as physical enhancements.

One might think that parental obligation to children ends with the end of childhood. I argue that if we consider why parents are obligated to their children, we will see that this view is false. Creating children exposes them to life’s risks. When we expose others to risks, we are often obligated to minimize damages and compensate for harms. Life’s risks last a lifetime, therefore parental obligation to one’s children does too. Grown children’s autonomy, and grown children’s independent responsibility for (...) some of their own problems, can sometimes limit what parental responsibility demands of parents but it doesn’t do away with the responsibility. I argue that my conclusions are not as counterintuitive as they might initially seem. I also consider the implications that parental obligation to grown children might have on the oft assumed obligation that grown children have to care for their parents. (shrink)

Researchers are developing a fertility preservation technique?testicular tissue cryopreservation (TTCP)?for prepubescent boys who may become infertile as a result of their cancer treatment. Although this technique is still in development, some researchers are calling for its widespread use. They argue that if boys do not bank their tissue now, they will be unable to benefit from any therapies that might be developed in the future. There are, however, risks involved with increasing access to an investigational procedure. This article examines four (...) methods of expanding access to TTCP: (1) expansion of institutional review board (IRB)-approved research trials; (2) offering TTCP as an innovative procedure in hospitals; (3) offering TTCP as a standard practice in hospitals; and (4) commercialization of TTCP. The ethical and practical implications of each are evaluated through a comparison with umbilical cord blood banking (UCBB), a technology that has achieved widespread use based on similar claims of future benefit.

The identification and valorization of unacknowledged, feminized forms of economic productivity has been an important task for feminist theory. In this article, we expand and rethink existing definitions of labour, in order to recognize the essential economic role women play in the stem cell and regenerative medicine industries, new fields of biomedical research that are rapidly expanding throughout the world. Women constitute the primary tissue donors in the new stem cell industries, which require high volumes of human embryos, oöcytes, foetal (...) tissue and umbilical cord blood. Such material is generally given for free in the advanced industrial democracies, constituted as a surplus (‘spare’ embryos) or waste (umbilical cord ‘afterbirth’, cadaveric foetuses, poor quality oöcytes) whose generative powers should not be withheld from others. At the same time, among impoverished female populations in developing nations, such biological material is now often procured through frankly transactional relations, where women undertake risky procedures for small fees. In each case, female bodily productivity is mobilized to support bioeconomic research, yet the economic value involved in these relations is largely unacknowledged. In this article, we consider both the gift economy and the transactional economy for reproductive tissues as a form of labour. In order to fully conceptualize the specificities of feminized productivity in the bioeconomy, we distinguish between earlier feminist theories of reproductive labour and the emerging practices generated by stem cell research, which we term regenerative labour. We consider how historical transformations in the regulation of feminized labour and the technical repertoires of stem cell research renegotiate the productivity limits of female reproductive biology, opening it out to novel and profitable forms of surplus value and enrolling women in complex negotiations over their role in bioeconomic activity.

Criticisms of the traditional clinical research pathway and its extensive oversight often focus on proposals for deregulation or assert that as in clinical treatment, clinical research should always offer benefit to patient-subjects. Proponents of medical innovation take a different, middle path, arguing that innovation is distinguishable from both research and treatment. This article considers this third pathway by examining stem cell-based innovation.Stem cell-based medical innovation is one pathway toward clinical translation. In fact, such an approach was taken in developing (...) class='Hi'>umbilical cord blood transplantation, which is now widely viewed as a safe and effective means for treating a range of malignant and non-malignant conditions. While the Guidelines for the Clinical Translation of Stem Cells created by the International Society for Clinical Research provide an approach to clinical translation that involves “responsible innovation” as an alternative to clinical research, there are at least four sets of unanswered questions regarding the use of an innovation pathway in this context that warrant careful attention.

A central part of Frege's logicism is his reconstruction of the natural numbers as equivalence classes of equinumerous concepts or classes. In this paper, I examine the relationship of this reconstruction both to earlier views, from Mill all the way back to Plato, and to later formalist and structuralist views; I thus situate Frege within what may be called the “rise of pure mathematics” in the nineteenth century. Doing so allows us to acknowledge continuities between Frege's and other approaches, but (...) also to understand better the motivation and the significance of his innovations, as well as their limits.

In common law, the traditional rule has been that there is no property in excised human tissue. In an era of widespread commodification of tissue, however, the practical reasons behind this position are increasingly outdated, while the philosophical grounds are paradoxical. This no-property rule has been construed so as to deprive tissue providers of ongoing rights, whereas researchers, universities, and biotechnology companies are prone to assume that once they acquire proprietary rights, those rights are complete and undifferentiated. That position can (...) and should be remedied, drawing on a modified Lockean concept of property in what we have laboured to create, and a more sophisticated jurisprudential understanding of property in the body as a bundle of rights. Particularly in the case of women’s tissues, such as ova and umbilical cord blood, this model can offer more effective protection against the global ‘enclosures’ of bodily tissue. (shrink)

Although the term commodification is sometimes criticised as imprecise or overused, in fact it has a complex philosophical ancestry and can never be used too much, because the phenomena that it describes are still gaining ground. The issues that commodification raises in relation to reproductive technologies include whether it is wrong to commodify human tissues generally and gametes particularly, and whether the person as subject and the person as object can be distinguished in modern biomedicine. This chapter examines three areas (...) in which commodification is a serious concern for important reproductive technologies: the sale of eggs for IVF and research, the banking of umbilical cord blood, and the use of gestational surrogates both domestically and internationally. Sales of human eggs for IVF or research are frequently disguised as “gifts”, which conceals the very real bodily risks and harms associated with ovarian hyperstimulation and egg harvesting undergone by egg “donors.” Umbilical cord banking is a fast-growing industry, with donated cord blood trading globally at very high prices; women who consent to banking of cord blood ostensibly for the potential future benefit of their child may not be informed of the likelihood that it will be traded in commercial markets or that the method used for harvesting may increase risks of jaundice in their babies. Commercial surrogacy also exploits altruism but in addition involves wrongful sale of babies, particularly in the international context. In each example, the commodification of women’s reproductive labour is masked by the manner in which ‘the lady vanishes’ under a gift model, ignoring the true economic value of their labour.

According to biomedical discourse, cord blood has been transformed from ‘waste’ to ‘clinical gold’ because of its potential for use in treatments. Private cord blood banks deploy clinical discourse to market their services to prospective parents, encouraging them to pay to bank cord blood as a form of ‘biological insurance’ to ensure their child’s future health. Social scientists have examined new forms of (bio)value produced in biological materials emergent with contemporary biotechnologies. This paper contributes (...) to this literature by examining the social and technical production of value in cord blood units collected for private banking. Value, in this paper is defined as a socio-cultural concept in which an object is made meaningful, or valuable, through its relations with social actors and within specific regimes of value. I draw on in-depth interviews with women who banked cord blood and key informants in private banks in Canada, to analyze how social actors produced cord blood as a valuable biological object. I show that a cord blood unit holds promissory value for women who bank and profit value for private banks and that these values are folded into each other and the biological material itself. Analyzing how specific cord blood units are made valuable provides insight into the multiple and possibly competing values of biological materials and the tensions that may arise between social actors and forms of knowledge during the valuing process.

What is its relationship to the tradition from which it emerges? The questions are difficult ones to answer in part because contemporary politics seems so schizophrenic. In affluent Western countries politics is increasingly a matter of spectacle on the one hand and managed economies on the other. Hannah Arendt seems quite confirmed in her claim that the once-glorious public realm of appearance is fundamentally degraded when it is overrun by concerns more appropriate to the private realm, such as household management and gossip. If this "unnatural growth of the natural" [47] inclines us to nostalgia for a time when the two realms were more decisively separated, such nostalgia is likely intensified by the "ethnic cleansing," rape camps, and genocide that we now associate with names such as "Yugoslavia" and "Rwanda." But as improbable as any flight to the past may be, it is even less likely that the politics of that past could help us navigate the treacherous waters of our current technological society. I have in mind not only the familiar claim that the attempted genocides of our time are only made possible by quite modern forms of technology, organization, and experience, 1 but also recent scientific and "medical" advances. Consider just two: first, the corporate driven and controlled development of biotechnologies, in which huge multinationals are acquiring patents to genetic "information" such as "all human blood cells that have come from the umbilical cord of [any] newborn child." If there is any doubt that such developments will lead us to redefine the human being, these may be laid to rest by the case of John Moore, an Alaskan businessman who found his own body parts had been patented, without his knowledge, by the University of California at Los Angeles and licensed to the Sandoz Pharmaceutical Corporation [Rifkin 60-61]. So much for Locke's attempt to ground the institution of private property in the fact that "every Man has a Property in his own Person"! 2 In its place we seem to be moving [End Page 38] toward something more like the "logical synthesis of biology and economy" called for by the National Socialist Institut allemand in Paris in 1942 [Agamben, Homo Sacer 145]. A similar process of redefinition is already underway in the field of death, a phenomenon that scientists and lawyers are having a harder and harder time pinning down. Where once death was defined by the cessation of the movement of the heart and lungs, recent life support technologies have forced scientists to define death in terms of such technologies. Witness Doctor Norman Shumway's defense of the definition of death as brain death: "I'm saying that anyone whose brain is dead is dead. It is the one determinant that would be universally applicable, because the brain is the one organ that can't be transplanted" [163]. By implication, if and when technology is developed that allows for brain transplants, even those whose brains are "dead" will be brought back to some kind of life, perhaps as organ farms for others who are less ambiguously alive.Giorgio Agamben, from whose book Homo Sacer: Sovereign Power and Bare Life I take both this last grisly example and its analysis, argues that, contrary to appearances, such developments do not represent a radical break with the tradition. His analysis both builds upon and corrects Michel Foucault's claim that politics in our time is constituted by disciplines of normalization and subjectification that Foucault labels "bio-power." For Foucault, biopower is fundamentally modern. "What might be called a society's 'threshold of modernity,'" he writes, "has been reached when the life of the species is wagered... (shrink)

It is increasingly suggested that shortages in the supply chain for human blood could be met by the development of techniques to manufacture human blood ex vivo. These techniques fall broadly under the umbrella of synthetic biology. We examine the biopolitical context surrounding the ex vivo culture of red blood cells through the linked concepts of alienation, immunity, bio-value and biosecuritization. We engage with diverse meanings of synthetic blood, and questions about how the discourses of biosecurity (...) and privatization of risk are linked to claims that the technology will address unmet needs and promote social justice. Through our discussion we contrast communitarian ideas that culturing red blood cells ‘extends the gift’ of adult blood donation with understandings of the immunitary logics that underpin the cord-blood economy.

Adenosine transport in cultured human umbilical vein endothelial cells (HUVEC) was characterized and shown to be mediated by a single facilitated diffusion mechanism. Initial rates of adenosine influx at 22 degrees C were saturable [apparent Michaelis constant, 69 +/- 10 mu M; maximum velocity (V-max), 600 +/- 70 pmol.10(6) cells(-1).s(-1)] and inhibited by nitrobenzylthioinosine (NBMPR). Formycin B had an unusually high affinity [inhibitory constant K-i), 18 +/- 4.3 mu M], whereas inosine had a low affinity (K-i, 440 +/- 68 (...) mu M) and nucleobases were without effect on adenosine influx. The number of transporters (1.2 x 10(6) sites/cell) was estimated by NBMPR equilibrium binding (apparent dissociation constant, 0.11 +/- 0.01 nM; maximum binding, 2.0 +/- 0.15 pmol/10(6) cells). In addition, we compared these endothelial cells with those obtained from cords from pregnancies complicated by diabetes (HUVEC-D), since embriopathy may occur in these conditions. HUVEC-D exhibited a 2.3-fold reduction in both the V-max for adenosine influx and the maximum number of NBMPR binding sites (260 +/- 40 pmol.10(6) cells(-1).s(-1) and 0.86 +/- 0.08 pmol/10(6) cells, respectively). However, the turnover number for each nucleoside transporter in normal and diabetic HUVEC was similar (approximate to 300 adenosine molecules/s). Adenosine metabolism at 10 mu M in HUVEC-D was modified compared with normal cells. Intracellular phosphorylation (> 90%) was the predominant pathway in normal HUVEC, whereas in HUVEC-D, substantial levels of adenine and adenosine were detected. The present results demonstrate therefore the downregulation of the NBMPR-sensitive nucleoside transporter and changes in adenosine metabolism in HUVEC from diabetic pregnancies. (shrink)

The establishment of a functional vascular system requires multiple complex steps throughout embryogenesis, from endothelial cell (EC) specification to vascular patterning into venous and arterial hierarchies. Following the initial assembly of ECs into a network of cord‐like structures, vascular expansion and remodeling occur rapidly through morphogenetic events including vessel sprouting, fusion, and pruning. In addition, vascular morphogenesis encompasses the process of lumen formation, critical for the transformation of cords into perfusable vascular tubes. Studies in mouse, zebrafish, frog, and human (...) endothelial cells have begun to outline the cellular and molecular requirements underlying lumen formation. Although the lumen can be generated through diverse mechanisms, the coordinated participation of multiple conserved molecules including transcription factors, small GTPases, and adhesion and polarity proteins remains a fundamental principle, leading us closer to a more thorough understanding of this complex event.

The method of explication has been somewhat of a hot topic in the last 10 years. Despite the multifaceted research that has been directed at the issue, one may perceive a lack of step-by-step procedural or structural accounts of explication. This paper aims at providing a structural account of the method of explication in continuation of the works of Geo Siegwart. It is enhanced with a detailed terminology for the assessment and comparison of explications. The aim is to provide means (...) to talk about explications including their criticisms and their interrelations. There is hope that this treatment will be able to serve as a foundation to a step-by-step guide to be established for explicators. At least it should help to frame and mediate explicative disputes. In closing the enterprise will be considered an explication of ‘explication’, though consecutive explications improving on this one are undoubtedly conceivable. (shrink)

This encyclopedia article provides a procedural account of explication outlining each step that is part of the overall explicative effort (2). It is prefaced by a summary of the historical development of the method (1). The latter part of the article includes a rough structural theory of explication (3) and a detailed presentation of an examplary explication taken from the history of philosophy and the foundations of mathematics (4).

This paper contributes to the calculization of evocation and erotetic implication as defined by Inferential Erotetic Logic (IEL). There is a straightforward approach to calculizing (propositional) erotetic implication which cannot be applied to evocation. First-order evocation is proven to be uncalculizable, i.e. there is no proof system, say FOE, such that for all X, Q: X evokes Q iff there is an FOE-proof for the evocation of Q by X. These results suggest a critique of the represented approaches to calculizing (...) IEL. This critique is expanded into a programmatic reconsideration of the IEL-definitions of evocation and erotetic implication. From a different point of view these definitions should be seen as desiderata that may or may not play the role of a point of orientation when setting up "rules of asking". (shrink)

The traditional use of the expression 'pseudoproblem' is analysed in order to clarify the talk of pseudoproblems and related phenomena. The goal is to produce a philosophically serviceable terminology that stays true to its historical roots. This explicative study is inspired by and makes use of the method of logical reconstruction. Since pseudoproblems are usually expressed by pseudoquestions a formal language of questions is presented as a possible reconstruction language for alleged pseudoproblems. The study yields an informal theory of pseudoproblems (...) whose presuppositions are critically investigated right away. At least one result remains: Claims of pseudoproblemship and their refutations must not be voiced casually - they are to be relativized and need substantial interpretive effort. (shrink)

We argue that the need for commentary in commonly used linear calculi of natural deduction is connected to the “deletion” of illocutionary expressions that express the role of propositions as reasons, assumptions, or inferred propositions. We first analyze the formalization of an informal proof in some common calculi which do not formalize natural language illocutionary expressions, and show that in these calculi the formalizations of the example proof rely on commentary devices that have no counterpart in the original proof. We (...) then present a linear natural deduction calculus that makes use of formal illocutionary expressions in such a way that unique readability for derivations is guaranteed – thus showing that formalizing illocutionary expressions can eliminate the need for commentary.

Questions are everywhere and the ubiquitous activities of asking and answering, as most human activities, are susceptible to failure – at least from time to time. This volume offers several current approaches to the systematic study of questions and the surrounding activities and works toward supporting and improving these activities. The contributors formulate general problems for a formal treatment of questions, investigate specific kinds of questions, compare different frameworks with regard to how they regulate the activities of asking and answering (...) of questions, and situate these activities in a wider framework of cognitive/epistemic discourse. From the perspectives of logic, linguistics, epistemology, and philosophy of language emerges a report on the state of the art of the theory of questions. (shrink)

Pseudoproblems, pseudoquestions, pseudosentences (etc.) constitute an iridescent group of concepts which were prominently used by the Vienna Circle (including Wittgenstein). In the course of an explication this paper presents a compilation of the many different meanings that were given to these expressions. This includes the more prominent Viennese approaches as well as a more recent one by Roy Sorensen. A novel proposal concerning the use ofthe term is made, suggesting that nothing is just a pseudoproblem, but only relative to a (...) certain state of discourse. While the paper follows an explicative methodology, several uses of 'pseudoproblem', including the explicated one, relate pseudoproblemhood to other kinds of analysis. (shrink)

Frege's philosophy of language includes detailed views on judgments. His formal logic - the Begriffsschrift - documents some of these views in the introduction and treatment of the judgment stroke. In current logic such an expression is either entirely ignored or, appearing as turnstile, plays an fundamentally different role. In this paper I put forward four claims: (i) Considering Frege's Begriffsschrift, it is methodologically palpable why the judgment stroke was omitted in nearly all logical systems developed after Frege. (ii) The (...) Frege-style inclusion of the judgment stroke in a formal language represents a partial implementation of results from speech act theory. (iii) A more comprehensive implementation, not limited to the judgment stroke, helps to satisfy justified expectations about formal languages and logical calculi. (iv) Such an implementation has not yet been achieved in the current logical mainstream. (shrink)
