In an era of evidence-based medicine and an increasing use of technology the question is raised again as to what extent emotions should play in medical and ethical decision-making. While clearly the correct facts in each case are a sine qua non for ethical decision-making, and one should evaluate each situation rationally in accord with accepted ethical principles, the appropriate role of the emotions in decision-making is gaining increased attention in part as a result of newer research in neuroethics. In end-of-life care there often exists a disconnect between the “rational” analysis by many philosophers and ethicists and the emotional reactions of many physicians and nurses with respect to the comparison between withholding and withdrawal of life-sustaining therapy. It is suggested that these attitudes of many health care workers should not be ignored because they represent a critical, almost universal, and laudable value of reluctance to take human life, a value so strongly ingrained in the ethos of the medical profession. 相似文献

A major challenge in integrative biology is understanding the mechanisms by which organisms regulate trade-offs among various functions competing for limiting resources. Key among these competing processes is the maintenance of health and the production of offspring. Optimizing both, given limited resources, can prove challenging. The physiological and behavioral changes that occur during reproduction have been shown to greatly influence an organism's immune system, which can have consequences for susceptibility to disease. Likewise, investing in costly immunological defenses can impair reproductive function. However, the precise nature of these physiological and behavioral interactions appears to be greatly dependent upon the environmental context in which they occur. Here we take a comparative look at interactions between the reproductive and immune systems, including current immunological approaches, and discuss how similar studies can reveal vastly disparate results. Specifically, we highlight results from the ornate tree lizard (Urosuarus ornatus) and the Siberian hamster (Phodopus sungorus) model systems, which provide an example of current research in the field. Collectively, these results emphasize the importance of resource availability and an individual's energy stores for the existence of life-history trade-offs and the efficiency of physiological processes in general. Akin to Dobzhansky's famous line, like other aspects of biology, nothing in ecoimmunology seems to make sense except in the context of an organism's environment. 相似文献
