This paper begins by developing a causal theory of mechanisms in medicine, and illustrates the theory with the example of the mechanism of the disease anthrax as elucidated by Koch. The causal approach to mechanisms is then compared to the Machamer, Darden, Craver (MDC) approach. At first sight the two approaches appear to be very different, but it is argued that the divergence is less than it ...

The synthesis and photodecomposition behaviour of a family of CO releasing molecules (CORMs) based on [Mn(CO)3bpy] derivatives connected to a semiconductor Quantum Dot (QD) sensitizer is described here. Compared to the non-sensitized complexes, such systems show a 2 to 6-fold increase of the photodecomposition rate upon irradiation with visible light.

The application of gaseous signaling molecules like NO, H2S or CO to overcome the multidrug resistance in cancer treatment has proven be a viable therapeutic strategy. development CO-releasing (CORMs) controlled manner and targeted tissues remains challenge medicinal chemistry. In this paper, we describe design, synthesis chemical enzymatic stability novel non-metal CORM (1) able release intrac...

More than 30 mineral elements have been found with different key functions in helping plants and animals to survive and live healthy. As a direct result, they have always attracted the attention of scientists. The quest is to find some efficient analytical and quantitative procedures in this study to determine some mineral and trace elements of Iranian Crocus sativus L. corms. Several studies h...

this experiment was carried out to investigate the effect of bulb harvesting time and indole butyric acid as well as changes of endogenous growth regulators, indole acetic acid and abscisic acid during scale propagation of lilium ledebourii (baker) boiss. treatments consisted of bulb harvesting time (0, 50, 100 and 150 days after flowering) in the natural habitat of damash, and iba concentratio...
