摘要： 据国际农业生物技术组织（ISAAA）最近发布的一份报告显示,2015年全球转基因作物种植首次出现下降.该年度全球28个国家包括玉米、棉花、大豆、油菜和其他作物在内的转基因作物总种植面积为4.44亿英亩,而2014年种植面积则为4.49亿英亩.据报告指出,下降的主要原因是由于全球农作物价格下降,作物整体种植面积减少所致.

关键词： anticipatory corpse   biopolitics   Foucault   germ-line modification   hermeneutics   human rights   practical reason   vulnerability  

摘要： This essay explores the two main objectives of Bishop's book, which he analyzes in the context of the care for the dying: (1) the medical metaphysics underlying medical science and (2) biopolitics as governance of the human body. This essay discusses Bishop's claims in view of newer developments in medicine, especially the turn to the construction of life, and confronts the concept of the patient's sovereignty with an alternative model of vulnerable agency. In order to overcome the impasses of contemporary bioethics, the essay argues that practical reason requires a two-fold ethics: first, it must develop a new hermeneutics of illness and disease, and second, in order to protect the individuals in the process of dying, moral claims concerning death must be based on the concept of human rights.

摘要： This article aims to develop a Lacanian approach to bioethics. Point of departure is the fact that both psychoanalysis and bioethics are practices of language, combining diagnostics with therapy. Subsequently, I will point out how Lacanian linguistics may help us to elucidate the dynamics of both psychoanalytical and bioethical discourse, using the movie One flew over the Cuckoo's Nest and Sophocles' tragedy Antigone as key examples. Next, I will explain the 'topology' of the bioethical landscape with the help of Lacan's three dimensions: the imaginary, the symbolical and the real. This will culminate in an assessment of the dynamics of bioethical discourse with the help of Lacan's theorem of the four discourses. Bioethics, I will argue, is not a homogeneous discourse. Rather, four modalities of bioethical discourse can be distinguished, all of them displaying specific weaknesses and strengths, opportunities and threats. This will be elucidated with the help of two case studies, namely the debates on human reproductive technologies and on the use of animals as biomedical research models.

关键词： Best interests   children's rights   pediatric bioethics   Republic of Georgia  

摘要： The United Nations Convention on the Rights of the Child has inspired numerous initiatives to recognize children's health-related rights. Whereas children's rights have served as the dominant moral framework for child health concerns in Europe, pediatric bioethics has emerged as the principal framework used in North America. Despite their similarities, these two frameworks differ significantly. Children's rights initiatives tend to be universalist, highlighting substantive standards for all children, while pediatric bioethics has developed norms, models, and procedures for the ethical analysis and management of individual cases. The aim of this article is to critically examine the respective contributions and intersections of children's rights and pediatric bioethics moral frameworks in child health. We describe our collaboration bridging our work with these two frameworks to address pediatric health-care concerns in the Republic of Georgia. We conclude with recommendations for how the complementarity of these two frameworks can be further bridged and promoted internationally.

摘要： 探究胚胎干细胞在Lewis肺癌中体内外抗肿瘤作用。方法:将30只实验小鼠分为两组,每组各15只,对实验组小鼠皮下接种Lewis肺癌细胞PBS悬液,隔日观察并记录小鼠皮下肿瘤生长状况。结果:实验组小鼠皮下肿瘤体积增大受到抑制,而对照组抑制作用不明显,差异具有统计学意义(P<0.05);实验组小鼠皮下存在实体肿瘤生长,且增加了内部肿瘤细胞凋亡,与对照组相比差异具有统计学意义(P<0.05)。结论:胚胎干细胞体外共培养可显著抑制Lewis肺癌细胞成瘤,增加了肿瘤组织中肿瘤细胞凋亡程度,表现了胚胎细胞在Lewis肺癌细胞中体内外抗瘤作用显著。
