Genetics: Medical, Theological and Ethical Aspects Tibbi, Dini ve Etik Boyutlariyla Genetik -/- Genetik bilimi biyolojinin botanik ve zooloji alanındaki uygulamalarını aşarak, sınırlarını önce antropolojiye sonra tıbba doğru hızla genişletmiştir. Öyle ki artık biyokimyadan onkolojiye kadar neredeyse tüm biyomedikal disiplinler, genetiğin kavramları, ilkeleri ve metodolojisi ile aşılanmıştır. Modern tıbbın uygulama alanında geniş bir yer tutan genetik bilimi, bir hastalığa dair risk analizi, teşhis ve tedavi seçeneklerinin belirlenmesi, prognozun değerlendirilmesi gibi klinik uygulamanın farklı evrelerinde söz sahibi olmaktadır. İçinde bulunduğumuz 21. yüzyılda (...) ise bu etkileşim eskisinden daha da güçlü hale gelerek devam etmektedir. Genetik biliminin klinikteki etkilerinin kapsamlı bir şekilde değerlendirildiği bu kitap, tüm dünyada tıbbın seyrini değiştirecek gelişmelere zemin teşkil eden genetik disiplininin olumlu ve olumsuz etkileri hakkında okuyucuya yetkili ağızlardan bilgiler taşımayı ve daha net bir fikir oluşturmayı hedeflemektedir. Kitapta dört ana bölüm bulunmaktadır. İlk bölümde doğum öncesi genetik uygulamalara, ikinci bölümde doğum sonrası (çocuk ve erişkinde) genetik testlere, üçüncü bölümde tıbbi genetiğin sıcak tartışma konusu olan Spinal Müsküler Atrofi’ye (SMA) ve dördüncü bölümde ise genetik bilgiyi felsefi bakışla ele alan makalelere yer verilmiştir. Genetiğin tıp pratiğini değiştirici ve dönüştürücü etkisine multidisipliner bir yaklaşımla ışık tutmayı amaçlayan bu eserin genetik hakkındaki Türkçe literatüre katkıda bulunmasını ümit ediyoruz.

Two genetic technologies capable of making heritable changes to the human genome have revived interest in, and in some quarters a very familiar panic concerning, so-called germline interventions. These technologies are: most recently the use of CRISPR/Cas9 to edit genes in non-viable IVF zygotes and Mitochondrial Replacement Therapy the use of which was approved in principle in a landmark vote earlier this year by the United Kingdom Parliament. The possibility of using either of these techniques in humans has encountered the (...) most violent hostility and suspicion. However it is important to be aware that much of this hostility dates back to the fears associated with In Vitro Fertilization and other reproductive technologies and by cloning; fears which were baseless at the time concerning both IVF and cloning the use of both of which have proved to be highly beneficial to humanity and which have been effectively regulated and controlled. This paper argues that CRISPR should by pursued through res.. (shrink)

Organ shortage is a major survival issue for millions of people worldwide. Globally 1.2 million people die each year from kidney failure. In this paper, we critically examine and find lacking extant proposals for increasing organ supply, such as opting in and opt out for deceased donor organs, and parochial altruism and paired kidney exchange for live organs. We defend two ethical solutions to the problem of organ shortage. One is to make deceased donor organs automatically available for transplant without (...) requiring consent from the donor or their relatives. The other is for society to buy nonvital organs in a strictly regulated market and provide them to people in need for free. (shrink)

This article approaches the problem of multifetal pregnancy reduction from a moral perspective. It is one of many complex moral issues arising from reproductive technology and is one with which midwives and nurses are faced more frequently with advancing technology. The work is intended to be used as an educational tool for those who prepare tomorrow’s nurses and midwives. The subject is discussed from three perspectives, the pregnant woman and her partner (clients), a midwife, and from a philosophical ethical perspective. (...) In an attempt to introduce a degree of reality, the perspective of the clients is presented as a dialogue. The midwife’s moral position and her professional difficulties are also discussed. The dialogue and discussion are supplemented with notes in which the issues raised by the characters are critically analysed and discussed. This article is designed to encourage reflection and critical thinking in tomorrow’s health care professionals, and in those who have the responsibility of educating them for a future where reproductive technology is posed to generate more major moral quandaries.

A number of philosophers maintain that the destruction of an embryo in the first 2 weeks after fertilization is not morally problematic as it is metaphysically impossible for any human organism to then have existed. We contend that the typical adult human organism was once a zygote so there is no metaphysical shortcut to justify early abortion. We show that five arguments against human organisms ever having been zygotes fail. All of the arguments have to do with one variant or (...) another of the zygote or early embryo dividing. They do not provide any reason to believe that since some adult organisms are not identical to zygotes due to earlier divisions, none could have been. (shrink)

In this paper a plea is made for an unprincipled approach to biomedical ethics, unprincipled of course just in the sense that the four principles are neither the start nor the end of the process of ethical reflection. While the four principles constitute a useful “checklist” approach to bioethics for those new to the field, and possibly for ethics committees without substantial ethical expertise approaching new problems, it is an approach which if followed by the bioethics community as a whole (...) would, the author believes, lead to sterility and uniformity of approach of a quite mindbogglingly boring kind. Moreover, much of bioethics is not concerned with identifying the principles or values appropriate to a particular issue, but rather involves analysing the arguments that are so often already in play and which present themselves as offering solutions in one direction or another. Here, as I try to show in discussion of these four scenarios, the principles allow massive scope in interpretation and are, frankly, not wonderful as a means of detecting errors and inconsistencies in argument.

We argue in this essay that (1) the embryo is an irredeemably ambiguous entity and its ambiguity casts serious doubt on the arguments claiming its full protection or, at least, its protection against its use as a means fo research, (2) those who claim the embryo should be protected as "one of us" are committed to a position even they do not uphold in their practices, (3) views that defend the protection of the embryo in virtue of its potentiality to (...) become a person fail, and (4) the embryo does not have any rights or interests to be protected. Given that many are willing to treat the embryo as a means in other practices, and that human embryonic stem cell (hESC) research holds the potential to benefit many people, one cannot but conclude that hESC research is permissible and, because of its immense promise for alleviating human even obligatory.

Genetics holds the key to understanding normal human biology and possibly many of the major causes of human disease and impairment. Research into human developmental genetics seems, therefore, to be both necessary and justified. However, such research requires the use of embryonic and fetal tissue obtained from spontaneous abortions and elective termination of pregnancy. This paper examines the arguments in favour of using tissue from elective terminations and the evolution of regulatory frameworks for this research. The paper argues that the (...) recent statutory and regulatory reforms in the UK have not properly addressed the issue of ethically obtaining postimplantation human embryos for research. It is argued that the recent reforms have left the Polkinghorne guidelines untouched but that these are now unequal to the task. A practical suggestion for reform of the approach to the informing and consent of potential donors is offered. (shrink)
