  1. Argument z niepewności normatywnej a etyczna ocena badań naukowych wykorzystujących ludzkie embriony.Tomasz Żuradzki - 2012 - Diametros 32:131-159.
    Konserwatywni przeciwnicy prowadzenia badań naukowych na ludzkich embrionach argumentują, że od momentu poczęcia mają one status moralny równy statusowi ludzi dorosłych: zarodki mają takie samo prawo do życia jak dorośli. W artykule przedstawiam oryginalną argumentację za tym stanowiskiem, której źródła można znaleźć w XVII-wiecznej teologii moralnej i współczesnej teorii decyzji. Argumentacja ta nie odwołuje się do statusu ontologicznego embrionów, ale do pewnego typu rozumowania praktycznego na temat tego, co należy robić w rozmaitych sytuacjach niepewności. Na pierwszy rzut oka wydaje się (...)

  2. 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 (...)

    In Vitro Analogies: Simulation Modeling in Bioengineering Sciences.Nancy Nersessian - forthcoming - In Tarja Knuuttila, Natalia Carrillo & Rami Koskinen (eds.), 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)

    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 (...)

  5. 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 (...)

    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.

Superfusion chambers containing ME slices were maintained in a constant temperature water-bath at 37∘C. Effluents were (...)

    “More on respect for embryos and potentiality: Does respect for embryos entail respect for in vitro embryos?”.Stephen S. Hanson - 2006 - Theoretical Medicine and Bioethics 27 (3):215-226.
    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 (...)

    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 (...)

    Artificial Gametes and Human Reproduction in the 21st Century: An Ethical Analysis.A. Villalba - 2024 - Reproductive Sciences.
    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. Various groups, such as same-sex couples, post-menopausal women, (...)

    Computer simulations constitute a significant scientific tool for promoting scientific understanding of natural phenomena and dynamic processes. Substantial leaps in computational force and software engineering methodologies now allow the design and development of large-scale biological models, which – when combined with advanced graphics tools – may produce realistic biological scenarios, that reveal new scientific explanations and knowledge about real life phenomena. A state-of-the-art simulation system termed Reactive Animation (RA) will serve as a study case to examine the contemporary philosophical debate (...)

    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 feed- ing 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 (...)

  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 (...)

    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 (...)

  19. 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.

    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 (...)

    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. (...)

  22. Algae communication, conspecific and interspecific: the concepts of phycosphere and algal-bacteria consortia in a photobioreactor (PBR).Sergio Mugnai, Natalia Derossi & Yogi Hale Hendlin - 2023 - Plant Signaling and Behavior 18.
    Microalgae in the wild often form consortia with other species promoting their own health and resource foraging opportunities. The recent application of microalgae cultivation and deployment in commercial photobioreactors (PBR) so far has focussed on single species of algae, resulting in multi-species consortia being largely unexplored. Reviewing the current status of PBR ecological habitat, this article argues in favor of further investigation into algal communication with conspecifics and interspecifics, including other strains of microalgae and bacteria. These mutualistic species form the (...)

    In this paper I present an argument in favour of a parental duty to use preimplantation genetic diagnosis (PGD). 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 (...)

    In this paper some classical representational ideas of Hertz and Duhem are used to show how the dichotomy between representation and intervention can be overcome. More precisely, scientific theories are reconstructed as complex networks of intervening representations (or representational interventions). The formal apparatus developed is applied to elucidate various theoretical and practical aspects of the in vivo/in vitro problem of biochemistry. Moreover, adjoint situations (Galois connections) are used to explain the relation berween empirical facts and theoretical laws in a (...)

    Because many involuntarily childless people have equal interests in benefitting from assisted reproductive technologies like in vitro fertilization as a mode of treatment, we have normative reasons to ensure inclusive access to such interventions for as many of these people as is reasonable and possible. However, the prevailing eligibility criterion for access to assisted reproductive technologies—'infertility'—is inadequate to serve the goal of inclusive access. This is because the prevailing frameworks of infertility, which include medical and social infertility, fail to (...)

    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 (...)

    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.

    Recent advances in stem cell research suggest that in the future it may be possible to create eggs and sperm from human stem cells through a process that we term in vitro gametogenesis (IVG). IVG would allow treatment of some currently untreatable forms of infertility. It may also allow same-sex couples to have genetically-related children. For example, cells taken from one man could potentially be used to create an egg, which could then be fertilised using naturally produced sperm from (...)

Intuitively many people believe it is wrong, but this belief is difficult to justify.

    Ontologies of living things are increasingly grounded on the concepts and practices of current life science. Biological development is a process, undergone by living things, which begins with a single cell and (in an important class of cases) ends with formation of a multicellular organism. The process of development is thus prima facie central for ideas about biological individuality and organismality. However, recent accounts of these concepts do not engage developmental biology.

  41. Genetically Modifying Livestock for Improved Welfare: A Path Forward.Adam Shriver & Emilie McConnachie - 2018 - Journal of Agricultural and Environmental Ethics 31 (2):161-180.
    In recent years, humans’ ability to selectively modify genes has increased dramatically as a result of the development of new, more efficient, and easier genetic modification technology. In this paper, we argue in favor of using this technology to improve the welfare of agricultural animals. We first argue that using animals genetically modified for improved welfare is preferable to the current status quo. Nevertheless, the strongest argument against pursuing gene editing for welfare is that there are alternative approaches to addressing (...)

  42. 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 (...)

  43. Embryo loss and double effect.Ezio Di Nucci - 2013 - Journal of Medical Ethics 39 (8):537-540.
    I defend the argument that if embryo loss in stem cell research is morally problematic, then embryo loss in in vivo conception is similarly morally problematic. According to a recent challenge to this argument, we can distinguish between in vivo embryo loss and the in vitro embryo loss of stem cell research by appealing to the doctrine of double effect. I argue that this challenge fails to show that in vivo embryo loss is a mere unintended side effect while (...)

  45. Emergence of Ciprofloxacin Resistance among Pseudomonas Aeruginosa Isolated from Burn Patients [hplimg].M. R. Shakibaie, S. Adeli & Y. Nikian - 2001 - Emergence: Complexity and Organization 26 (3&4).
    Background: Increasing resistance of Pseudomonas aeruginosa to ciprofloxacin in ICU/burn units has created a problem in the treatment of infections caused by this microorganism. -/- Methods: Fifty P. aeruginosa strains were isolated from burn patients hospitalized in the Kerman Hospital during May 1999-April 2000 and were tested for in-vitro sensitivity to different antibiotics by disc diffusion breakpoint assay. The isolates were subjected to minimum inhibitory concentration (MIC) test by agar dilution method. Existence of the plasmids was also investigated in (...)

  47. A situation of ethical limbo and preimplantation genetic diagnosis.Tomasz Żuradzki - 2014 - Journal of Medical Ethics 40 (11):780-781.
    In my previous paper I argued that if in vitro fertilization (IVF) is legal and practiced there is no moral ground to object to legalization of preimplantation genetic diagnosis (PGD). My opponent raises an objection that my paper “fails to address the ethical argumentation of one key opponent of IVF – the Catholic Church”. In this reply I show that her/his thesis that embryos created during IVF are in ‘ethical limbo’ and “fall outside the moral universe of Christian ethics” (...)

    OBJETIVO A gestação nos mamíferos domésticos é um processo fisiológico que implica mudanças físicas, metabólicas e hormonais na fêmea, que culminam com o nascimento de um novo indivíduo. Desta forma, a compreensão de tais mudanças e como estas favorecem um ambiente ideal de desenvolvimento embrionário inicial, até a placentação e a fisiologia envolvidas durante esses processos é fundamental na tomada de decisões quanto à saúde reprodutiva da fêmea, na seleção de futuras matrizes e até mesmo para a saúde fetal e (...)
