Uncoupling proteins (UCPs) regulate mitochondrial function, and thus cellular metabolism. Angiotensin‐converting enzyme (ACE) is the central component of endocrine and local tissue renin–angiotensin systems (RAS), which also regulate diverse aspects of whole‐body metabolism and mitochondrial function (partly through altering mitochondrial UCP expression). We show that ACE expression also appears to be regulated by mitochondrial UCPs. In genetic analysis of two unrelated populations (healthy young UK men and Scandinavian diabetic patients) serum ACE (sACE) activity was significantly higher amongst UCP3‐55C (rather than (...) T) and UCP2 I (rather than D) allele carriers. RNA interference against UCP2 in human umbilical vein endothelial cells reduced UCP2 mRNA sixfold (P < 0·01) whilst increasing ACE expression within a physiological range (<1·8‐fold at 48 h; P < 0·01). Our findings suggest novel hypotheses. Firstly, cellular feedback regulation may occur between UCPs and ACE. Secondly, cellular UCP regulation of sACE suggests a novel means of crosstalk between (and mutual regulation of) cellular and endocrine metabolism. This might partly explain the reduced risk of developing diabetes and metabolic syndrome with RAS antagonists and offer insight into the origins of cardiovascular disease in which UCPs and ACE both play a role.

Students of the history of ethics sometimes find themselves tempted by moderate or extreme versions of an approach that might roughly be called ‘historicist’. This temptation may result from the difficulties of approaching historical texts from a ‘narrowly philosophical’ point of view. We may begin, for instance, by wanting to know what Aristotle has to say about ‘the problems of ethics’, so that we can compare his views with those of Aquinas, Hume, Kant, Sidgwick, and Rawls, and then decide what (...) is true or false in each theorist's position. But this narrowly philosophical attitude soon runs into difficulties, and writers on the history of ethics often warn us against it. (shrink)

Etymology might encourage us to begin a discussion of Aristotle on philanthropy with a discussion of philanthropia ; and it is instructive to see why this is not quite the right place to look. The Greek term initially refers to a generalized attitude of kindness and consideration for a human being. The gods accuse Prometheus of being a ‘human-lover’, intending the term in an unfavorable sense, when he confers on human beings the benefits that should have been confined to the (...) gods. Aristotle uses the abstract noun only once, to refer to sympathetic fellow-feeling ; and he mentions our feeling of kinship with other human beings to explain our approval of the philanthropos person. Philanthropia is the attitude of a kind and considerate person, even if she lacks material resources, and it can be displayed without the transfer of material resources. (shrink)

IT HAS OFTEN BEEN SUPPOSED that Aristotle's account of thought and action imposes severe limits on the functions and scope of practical reason; and insofar as Thomas Aquinas accepts Aristotle's account, he seems to be forced into the same restrictive view of practical reason. Practical reason expresses itself primarily in deliberation ; and the virtue that uses practical reason correctly is the deliberative virtue of prudence. Aristotle believes that deliberation is confined to means to ends, while will is focused on (...) ends. Some ends that are assumed on some occasions may on other occasions also count as means to more ultimate ends; but it seems that the most ultimate ends must be taken for granted in any deliberation. Since every deliberation must take for granted some end to which the deliberation finds means, the conclusions of rational deliberation must ultimately be about means to ultimate ends that are not themselves subject to practical reason.
