The endothelium is a monolayer of cells, called endothelial cells, that lines the interior of blood vessels, including arteries, veins and cardiac chambers, 1 acting as a protective layer between circulating blood and other tissues. 2 The endothelium is crucial for the control of vascular homeostasis, and is involved in the regulation of intracellular signaling, 1 vascular tonus ?script=sci_arttext&pid=S

  For this reason, medicinal chemists have long sought agents that selectively generate cell-killing reactive intermediates under hypoxic conditions. The compound 3-amino-1,2,4-benzotriazine 1,4-dioxide (tirapazamine) is the most promising hypoxia-selective antitumor agent discovered to ://~gatesk.   A study into the kinetics of a chemical reaction is usually carried out with one or both of two main goals in mind: 1. Analysis of the sequence of elementary steps giving rise to the overall reaction. i.e. the reaction mechanism. 2. Determination of the absolute rate of the reaction and/or its individual elementary

Abstract. Temperature-programmed desorption and transient kinetics were found to be powerful complementary techniques for providing the important distinction between stable C-O complexes and reactive C(O) intermediates on the surface of coal- and polymer-derived chars.

Knowledge of the reactive surface area (RSA) of these materials is necessary for understanding the variations in their Abstract. The affinities of a series of azines for nitrosonium ion (A NO +) were calculated by quantum-chemical methods, AM1 and ab A NO + values were found to increase as the number of nitrogen atoms in the ring decreases and the donor power of substituents increases; ring fusion also increases A NO +.The best agreement between the calculated and experimental A NO + values was Scientists discover new clue behind age-related diseases and food spoilage - posted in BioscienceNews.
