Trace elements and vitamins in membrane function.
The title of this article might well have sprung directly from an examination question, for example ‘Discuss the role of trace elements and vitamins in membrane function’. One could imagine perplexed students, faced with this enigmatic problem, racking their memories for some clue to the thoughts of a perverse examiner. For of course, the question is meaningless. There is no systematic reason w...
متن کاملNitric Oxide and Cardiac Function
Nitric oxide (NO) is produced from virtually all cell types composing the myocardium and regulates cardiac function through both vascular-dependent and -independent effects. The former include regulation of coronary vessel tone, thrombogenicity, and proliferative and inflammatory properties as well as cellular cross-talk supporting angiogenesis. The latter comprise the direct effects of NO on s...
متن کاملNitric oxide and synaptic function.
The free radical gas nitric oxide (NO) is a recently identified neuronal messenger that carries out diverse signaling tasks in both the central and peripheral nervous systems. Whereas most neurotransmitters are packaged in synaptic vesicles and secreted in a Ca2+-dependent manner from specialized nerve endings, NO is an unconventional transmitter which is not packaged in vesicles, but rather di...
متن کاملNitric oxide and cardiac function.
Nitric oxide (NO) participates in the control of contractility and heart rate, limits cardiac remodeling after an infarction and contributes to the protective effect of ischemic pre- and postconditioning. Low concentrations of NO, with production of small amounts of cGMP, inhibit phosphodiesterase III, thus preventing the hydrolysis of cAMP. The subsequent activation of a protein-kinase A cause...
متن کاملNitric oxide function in atherosclerosis
Atherosclerosis is a chronic inflammatory process in the intima of conduit arteries, which disturbs the endothelium-dependent regulation of the vascular tone by the labile liposoluble radical nitric oxide (NO) formed by the constitutive endothelial nitric oxide synthase (eNOS). This defect predisposes to coronary vasospasm and cardiac ischaemia, with anginal pain as the typical clinical manifes...
