  1. Embriones supernumerarios en las técnicas de reproducció humana asisitida. ¿Qué hacer con ellos? Análisis jurídico y ético de las opciones legales en España.Oscar Vergara - 2015 - Revista Derecho Genética Humana 43:59 - 81.
    La FIV puede llevar aparejada la acumulación de embriones humanos excedentes. Aunque la ley prevé varios posibles destinos, las clínicas de reproducción asistida, que con frecuencia han de decidir qué hacer con ellos, buscan criterios para hacerlo de la forma más razonable posible. Este trabajo pretende aportar razones jurídicas y éticas que ayuden a esa decisión.

  2. Transhumanism, in vitro fertilization and woman dignity.Carlos Alberto Rosas Jimenez - 2020 - In Diana Stephania Muñoz-Gomez, La persona: on-off Desafíos de la familia en la cuarta revolución industrial. pp. 304-317.
    Transhumanism is a movement that seeks to transcend certain limitations inherent in the human condition as we know it. But does it justify overriding the dignity of current human beings in order to satisfy the desire to increase human potential and improve human beings as such, in order to obtain other human beings? Does it justify disregarding the dignity of women in order to obtain new human beings through fertilization? To answer these questions, we have made a sweep over the (...)

  3. In Vitro Analogies: Simulation Modeling in Bioengineering Sciences.Nancy Nersessian - forthcoming - In Tarja Knuuttila, Natalia Carrillo & Rami Koskinen, Routledge Handbook of Scientific Modeling. Routledge.
    This chapter focuses on a novel class of models used in frontier research in the bioengineering sciences – in vitro simulation models – that provide the basis for biological experimentation. These bioengineered models are hybrid constructions, composed of living tissues or cells and engineered materials. Specifically, it discusses the processes through which in vitro models were built, experimented with, and justified in a tissue engineering lab. It examines processes of design, construction, experimentation, evaluation, and redesign of in (...) simulation models, in general, as instances of building the source analogy (as distinguished from retrieving an analogy), which figures prominently in creative frontier scientific research. Building the analogical source is a bootstrapping process, which furthers the articulation, as well as the solution of the problem. -/- . (shrink)

  4. The Ethics of Producing In Vitro Meat.G. Owen Schaefer & Julian Savulescu - 2014 - Journal of Applied Philosophy 31 (2):188-202.
    The prospect of consumable meat produced in a laboratory setting without the need to raise and slaughter animals is both realistic and exciting. Not only could such in vitro meat become popular due to potential cost savings, but it also avoids many of the ethical and environmental problems with traditional meat productions. However, as with any new technology, in vitro meat is likely to face some detractors. We examine in detail three potential objections: 1) in vitro meat (...)

  6. Production of mutants of Tobacco Mosaic Virus by chemical alteration of its nucleic acid in vitro.Alfred Gierer & K. W. Mundry - 1958 - Nature 182:1457-1458.
    The generation of viral mutants in vitro was demonstrated by treatment of the isolated RNA of Tobacco Mosaic Virus by nitrous acid. This agent causes deaminations converting cytosine into uracil, and adenine into hypoxanthine. Our assay for mutagenesis was the production of local lesions on a tobacco variety on which the untreated strain produces systemic infections only. A variety of different mutants are generated in this way. Quantitative analysis of the kinetics of mutagenesis leads to the conclusion that alteration (...)

  9. Neuroendocrine study of the Korean native cattle: Pulsatile LHRH release from hypothalamic tissues superfused in vitro.Sun Kyeong Yu - 1989 - Korean Journal of Zoology 32 (3):275-280.
    The present study examined the endogenous release of luteinizing hormone-releasing hormone (LHRH) from superfused hypothalamic slices derived from Korean native cattie (KNC). In addition, the in vitro secretory pattern of LHRH release in '(NC was compared with that in imported cattle such as Holstein cow. The median eminences (ME) of hypothalamic tissues were dissected out, sliced, and quickly placed in an ice-cold superfusion chamber. Superfusion chambers containing ME slices were maintained in a constant temperature water-bath at 37∘C. Effluents were (...)

    Molecular developmental biology has expanded our conceptions of gene actions, underpinning that embryonic development is not only governed by a set of specific genes, but as much by space–time conditions of its developing modules. Typically, formation of cellular spheres, their transformation into planar epithelia, followed by tube formations and laminations are modular steps leading to the development of nervous tissues. Thereby, actions of organising centres, morphogenetic movements, inductive events between epithelia, tissue polarity reversal, widening of epithelia, and all these occurring (...)

    It is commonly assumed that persons who hold abortions to be generally impermissible must, for the same reasons, be opposed to embryonic stem cell research [ESR]. Yet a settled position against abortion does not necessarily direct one to reject that research. The difference in potentiality between the embryos used in ESR and embryos discussed in the abortion debate can make ESR acceptable even if one holds that abortion is impermissible. With regard to their potentiality, in vitro embryos are here (...)

  14. Other Fecundities: Proust and Irigaray on Sexual Difference.Lisa Guenther - 2010 - Differences 21 (2).
    Irigaray's early work seeks to multiply possibilities for women's self-expression by recovering a sexual difference in which male and female are neither the same nor opposites, but irreducibly different modes of embodiment. In her more recent work, however, Irigaray has emphasized the duality of the sexes at the expense of multiplicity, enshrining the heterosexual couple as the model of sexual ethics. Alison Stone's recent revision of Irigaray supplements her account of sexual duality with a theory of bodily multiplicity derived from (...)

    Artificial gametes, derived from stem cells, have the potential to enable in vitro fertilization of embryos. Currently, artificial gametes are only being generated in laboratory animals; however, considerable efforts are underway to develop artificial gametes using human cell sources. These artificial gametes are being proposed as a means to address infertility through assisted reproductive technologies. Nonetheless, the availability of artificial gametes obtained from adult organisms can potentially expand the possibilities of reproduction.

  16. Does Reproductive Justice Demand Insurance Coverage for IVF? Reflections on the Work of Anne Donchin.Carolyn McLeod - 2017 - International Journal of Feminist Approaches to Bioethics 10 (2):133-143.
    This paper comes out of a panel honoring the work of Anne Donchin (1940-2014), which took place at the 2016 Congress of the International Network on Feminist Approaches to Bioethics (FAB) in Edinburgh. My general aim is to highlight the contributions Anne made to feminist bioethics, and to feminist reproductive ethics in particular. My more specific aim, however, is to have a kind of conversation with Anne, through her work, about whether reproductive justice could demand insurance coverage for in (...) fertilization. I quote liberally from Anne’s work for this purpose, but also to shower the reader with her words, reminding those of us who knew her well what a wonderful colleague she was. (shrink)

    What role should legislation or policy play in avoiding the complications of in-vitro fertilization? In this article, we focus on single versus double embryo transfer, and assess three arguments in favour of mandatory single embryo transfer: risks to the mother, risks to resultant children, and costs to society. We highlight significant ethical concerns about each of these. Reproductive autonomy and non-paternalism are strong enough to outweigh the health concerns for the woman. Complications due to non-identity cast doubt on the (...)

  22. Duty and the Beast: Should We Eat Meat in the Name of Animal Rights?Andy Lamey - 2019 - Cambridge, UK: Cambridge University Press.
    The moral status of animals is a subject of controversy both within and beyond academic philosophy, especially regarding the question of whether and when it is ethical to eat meat. A commitment to animal rights and related notions of animal protection is often thought to entail a plant-based diet, but recent philosophical work challenges this view by arguing that, even if animals warrant a high degree of moral standing, we are permitted - or even obliged - to eat meat.

    It is well known that there is a shortage of human ova for in vitro fertilization (IVF) purposes, but little attention has been paid to the way in which the demand for ova in stem-cell technologies is likely to exacerbate that shortfall and create a trade in human eggs. Because the 'Dolly' technology relies on enucleated ova in large quantities, allowing for considerable wastage, there is a serious threat that commercial and research demands for human eggs will grow exponentially (...)

    Recent breakthroughs in stem cell differentiation and reprogramming suggest that functional human gametes could soon be created in vitro. While the ethical debate on the uses of in vitro generated gametes (IVG) was originally constrained by the fact that they could be derived only from embryonic stem cell lines, the advent of somatic cell reprogramming, with the possibility to easily derive human induced pluripotent stem cells from any individual, affords now a major leap in the feasibility of IVG (...)

    In a century from agitated cells to human organoids.Paul Gottlob Layer - 2024 - J Neurosci Methods 405.
    Reaching back more than a century, suspension cultures have provided major insights into processes of histogenesis; e.g., cell communication, distinction of self/nonself, cell sorting and cell adhesion. Besides studies on lower animals, the vertebrate retina served as excellent reaggregate model to analyze 3D reconstruction of a complex neural laminar tissue. Methodologically, keeping cells under suspension is essential to achieve tissue organisation in vitro; thereby, the environmental conditions direct the emergent histotypic particulars.

    Previous studies have shown that zinc deficiency leads to apoptosis of neuronal precursor cells in vivo and in vitro. In addition to the role of p53 as a nuclear transcription factor in zinc deficient cultured human neuronal precursors (NT-2), we have now identified the translocation of phosphorylated p53 to the mitochondria and p53-dependent increases in the pro-apoptotic mitochondrial protein BAX leading to a loss of mitochondrial membrane potential as demonstrated by a 25% decrease in JC-1 red:green fluorescence ratio.

    The essay questions the role of neurons in the concept of mind. The mind is considered as an emerging but physical property of the brain: a mental brain configuration does exist. This configuration is relatively resistant to brain damage, coma, hypoxia and normal (electro)physiological brain states and is envisioned as a relatively stable (nearly anatomical) structure. Consistent with this idea is that, despite the lifetime turnover of their constituents (e.g. proteins and nucleotides) and morphological changes, brain neurons do not divide. (...)

I argue that if embryos created in vitro were able to decide for themselves in a rational manner, they would sometimes choose PGD as a method of selection. Couples, therefore, should respect their hypothetical choices on a principle similar to that of patient autonomy. My thesis shows that no matter which moral doctrine couples subscribe to, they ought to conduct the (...)

    Mitochondrial replacement therapy requires oocytes of women whose mitochondrial DNA will be transmitted to resultant children. These techniques are scientifically, ethically and socially controversial; it is likely that some women who donate their oocytes for general in vitro fertilisation usage would nevertheless oppose their genetic material being used in MRT. The possibility of oocytes being used in MRT is therefore relevant to oocyte donation and should be included in the consent process when applicable. In present circumstances, specific consent should (...)

This is because the prevailing frameworks of infertility, which include medical and social infertility, fail to (...)

  38. Receptacle/ Chōra: Figuring the Errant Feminine in Plato's Timaeus.Emanuela Bianchi - 2001 - Hypatia 21 (4):124-146.
    This essay undertakes a reexamination of the notion of the receptacle/chōra in Plato's Timaeus, asking what its value may be to feminists seeking to understand the topology of the feminine in Western philosophy. As the source of cosmic motion as well as a restless figurality, labile and polyvocal, the receptacle/chōra offers a fecund zone of destabilization that allows for an immanent critique of ancient metaphysics. Engaging with Derridean, Irigarayan, and Kristevan analyses, Bianchi explores whether receptacle/chōra can exceed its reduction to (...)

At the same time it wants to demonstrate that this notion of justice is directly related to the ideas of expression and nudity. Due to which the “Other” imposes (...)

    Fetal reduction is the practice of reducing the number of fetuses in a multiple pregnancy, such as quadruplets, to a twin or singleton pregnancy. Use of assisted reproductive technologies increases the likelihood of multiple pregnancies, and many fetal reductions are done after in vitro fertilisation and embryo transfer, either because of social or health-related reasons. In this paper, I apply Joe Horton’s all or nothing problem to the ethics of fetal reduction in the case of a twin pregnancy. I (...)

    Imagine a world where everyone is healthy, intelligent, long living and happy. Intuitively this seems wonderful albeit unrealistic. However, recent scienti c breakthroughs in genetic engineering, namely CRISPR/Cas bring the question into public discourse, how the genetic enhancement of humans should be evaluated morally. In 2001, when preimplantation genetic diagnosis (PGD) and in vitro fertilisation (IVF), enabled parents to select between multiple embryos, Julian Savulescu introduced the principle of procreative bene cence (PPB), stating that parents have the obligations to (...)

  42. Victor Turner's The Ritual Process Afterword in English for German Translation. [REVIEW]Eugene Halton - manuscript
    English manuscript version of Afterword to German translation of Victor Turner's The Ritual Process. The Ritual Process is a pivotal book in the body of Victor Turner's works. The first three chapters, drawn from Turner's Henry Morgan lectures at the University of Rochester, reveal the richness and subtlety of his analysis of tribal ritual and social life. In the third chapter, he concentrates on the aspects of liminality and communitas found in Ndembu ritual and expands these in the remainder of (...)

  43. Affecting future individuals: Why and when germline genome editing entails a greater moral obligation towards progeny.Davide Battisti - 2021 - Bioethics 35 (5):1-9.
    Assisted reproductive technologies have greatly increased our control over reproductive choices, leading some bioethicists to argue that we face unprecedented moral obligations towards progeny. Several models attempting to balance the principle of procreative autonomy with these obligations have been proposed. The least demanding is the minimal threshold model (MTM), according to which every reproductive choice is permissible, except creating children whose lives will not be worth living. Hence, as long as the future child is likely to have a life worth (...)

  44. Is There a Right to the Death of the Foetus?Eric Mathison & Jeremy Davis - 2017 - Bioethics 31 (4):313-320.
    At some point in the future – perhaps within the next few decades – it will be possible for foetuses to develop completely outside the womb. Ectogenesis, as this technology is called, raises substantial issues for the abortion debate. One such issue is that it will become possible for a woman to have an abortion, in the sense of having the foetus removed from her body, but for the foetus to be kept alive. We argue that while there is a (...)

  45. Emerging profiles for cultured meat; ethics through and as design.C. Weele, van der & C. P. G. Driessen - 2013 - Animals 3 (3):647-662.
    The development of cultured meat has gained urgency through the increasing problems associated with meat, but what it might become is still open in many respects. In existing debates, two main moral profiles can be distinguished. Vegetarians and vegans who embrace cultured meat emphasize how it could contribute to the diminishment of animal suffering and exploitation, while in a more mainstream profile cultured meat helps to keep meat eating sustainable and affordable. In this paper we argue that these profiles do (...)

  46. Sewall Wright’s adaptive landscapes: 1932 vs. 1988.Massimo Pigliucci - 2008 - Biology and Philosophy 23 (5):591-603.
    Sewall Wright introduced the metaphor of evolution on “adaptive landscapes” in a pair of papers published in 1931 and 1932. The metaphor has been one of the most influential in modern evolutionary biology, although recent theoretical advancements show that it is deeply flawed and may have actually created research questions that are not, in fact, fecund. In this paper I examine in detail what Wright actually said in the 1932 paper, as well as what he thought of the matter at (...)

  47. Why we should not extend the 14-day rule.Bruce Philip Blackshaw & Daniel Rodger - 2021 - Journal of Medical Ethics (10):712-714.
    The 14-day rule restricts the culturing of human embryos in vitro for the purposes of scientific research for no longer than 14 days. Since researchers recently developed the capability to exceed the 14-day limit, pressure to modify the rule has started to build. Sophia McCully argues that the limit should be extended to 28 days, listing numerous potential benefits of doing so. We contend that McCully has not engaged with the main reasons why the Warnock Committee set such a (...)

  48. Fertilidade em Vacas Leiteiras: Fisiologia e Manejo.Emanuel Isaque Cordeiro da Silva - manuscript
    FERTILIDADE EM VACAS LEITEIRAS: FISIOLOGIA E MANEJO -/- INTRODUÇÃO -/- A fertilidade das vacas com aptidão leiteira tem apresentado queda de quase 1% ao ano nos últimos 30 anos como apresentam os estudos acerca da reprodução de bovinos leiteiros; essa diminuição tem coincidido com um aumento sustentado na produção de leite. Estudos realizados a partir da década de 1960 pelo NRC, demonstraram que nos rebanhos leiteiros da América do Norte, nessa década, era conseguido emprenhar até 65% das vacas inseminadas, enquanto, (...)

  49. Lab-Grown Meat and Veganism: A Virtue-Oriented Perspective.Carlo Alvaro - 2019 - Journal of Agricultural and Environmental Ethics 32 (1):127-141.
    The project of growing meat artificially represents for some the next best thing to humanity. If successful, it could be the solution to several problems, such as feeding a growing global population while reducing the environmental impact of raising animals for food and, of course, reducing the amount and degree of animal cruelty and suffering that is involved in animal farming. In this paper, I argue that the issue of the morality of such a project has been framed only in (...)
