Can Bioethics be Lutheran?

Abstract :  A Lutheran bioethics must rest on a reconstructed version of Martin Luther's ethics. In the article it is shown that this ethics is Christian in that it has faith in Jesus Christ as its source. But the ethics of neighbor love is practiced in the secular world where it to some extent corresponds with natural law ethics. A Christian believer acts ethically both as an individual and as a citizen. Against the background of this understanding of Lutheran ethics, the position of Ted Peters and Gilbert Meilaender on genetics and stem cells is presented and criticized. One conclusion is that there is no Lutheran doctrine on the status of the human embryo.     

死亡的判定

死亡是生命的终结.死亡判定的标准在历史上经历了一个逐步深化的过程.1959年2位法国医学家首先提出了脑死亡的概念.但是什么是脑死亡,以及如何判定脑死亡是一个有争议的问题.1981年美国总统委员会提出了一个脑死亡的判定指标体系,并被一些国家立法接受.回顾了对死亡判定认识的历史过程.     

模型方法在神经干细胞研究中的应用

神经干细胞(neural stem cell NSC)是一种终身具有自我更新能力的细胞,其子细胞能分化产生神经系统的各类细胞,这一特性为神经系统各类疾病的治疗带来了新的希望.模型方法是医学研究的基本方法.就模型方法在神经干细胞研究中的应用作一综述有重要意义.     

骨髓间充质干细胞移植治疗感音神经性聋的进展及评价

目前感音神经性聋缺乏直接有效的药物治疗措施,基因治疗及干细胞移植治疗为临床治疗提供新的思路。骨髓间充质干细胞具有异于其他干细胞的优点,耳蜗内移植后能起到基因治疗的目的,并有潜在的分化为内耳功能细胞的功能,但仍面临诸多尚待解决的问题。     

鉴定干细胞源胰岛素分泌细胞的方法及其利弊

在诱导各种干细胞向胰岛素分泌细胞(insulin producing cells,IPCs)分化的研究中,或多或少地存在着分化效率低、分化细胞不够成熟以及分泌产物的性质难以确定等问题,而IPCs的功能决定了其治疗糖尿病的效果,也是衡量各种诱导方案的重要指标。如何合理、科学地对IPCs进行形态与功能鉴定本文对此加以探讨。     

感染后与非感染后肠易激综合征的多维特点

探讨感染后(PI)与非感染后肠易激综合征(NPI-IBS)的临床,精神心理,组织学特点。取IBS患者和正常人进行问卷调查,了解其多维特点。分别检测肥大细胞的数目。结果显示:(1)PI-IBS与NPI-IBS患者临床、心理特征不同;(2)IBS两组患者肥大细胞的数目无差异,与对照组比较差异明显。因此认为PI-IBS和NPI-IBS有特征差异,对临床治疗有一定指导意义。     

Editorial Introduction to the Special Issue: Using Story Completion Methods in Qualitative Research

ABSTRACT

What is story completion? How come I’ve never heard of it? Can it be useful for me as a qualitative researcher? A relatively unknown method for qualitative data collection, story completion has a long history of use in psychotherapy practice and (quantitative) developmental psychology research. We believe it has untapped, exciting potential as a qualitative technique in and beyond psychology, offering something quite different to many of the popular methods (e.g., interviews, focus groups). In this article, an introduction to an exciting Special Issue that discusses and demonstrates the potential of story completion, we provide a brief history of the development of story completion as a qualitative technique and an overview of design, sampling, and data analysis in story completion research. We finish by highlighting potential pitfalls of story completion, alongside a discussion of the possibilities it offers, and briefly introduce the empirical papers in the Special Issue.     

AN INCLUSIVE ETHICS FOR THE TWENTY-FIRST CENTURY: IMPLICATIONS FOR STEM CELL RESEARCH

An important contribution of Christian ethics in the pluralistic world of the twenty‐first century is to emphasize inclusivity. Rather than promoting the interests of certain groups at the expense of the most vulnerable, society does well to prioritize ways forward that benefit all. For stem cell research, inclusivity entails benefiting or at least protecting the beneficiaries of treatment, the sources of materials, and the subjects of research. Adult stem cells are already benefiting many ill patients without causing harm, and select adult cells may prove even more beneficial in the future. Other types of stem cells require other bodily materials such as eggs and somatic cells that should be obtained without unduly harming those who provide them. Research subjects, especially the most vulnerable, require protection as well. Should human embryos be included among them? Considerations of location, formation, individuation, and intention are here examined. Ultimately, for safety reasons as well as workability, pluripotency, and compatibility, relatively new types of pluripotent stem cells, especially induced pluripotent stem cells, warrant special priority according to an inclusive ethics.     

Increased accessibility of semantic concepts after (more or less) subtle activation of related concepts: support for the basic tenet of priming research

Abstract

Increasingly remote concepts and behaviors have been primed, which have come under increasing criticism. In this present experiment, we take a step back and try to strengthen the roots of priming research. In this experiment, we systematically varied the activation or priming of a concept in six experiments (N?=?1285). We then measured accessibility for semantic concepts using a word stem completion task. Across the six experiments, our investigations showed that the activation of semantic concepts is possible through greater accessibility of semantically congruent words (with only one experiment failing to reach a conventional level of significance). These results provide a prerequisite for further investigation into behavioral priming. The present experiment showed that the basal priming mechanisms are robust effects. The meta-analytic integration showed that women reliably had access to more baby-related words. A possible explanation is that social role stereotypes associate women more with the reproductive sphere than men and that women, to a certain extent, internalize these societal views. Other explanations and potential future applications are discussed.
