A phosphodiesterase that inhibits this process is blocked by sildenafil.
Hair growth is a side effect of a class of drugs that facilitates this process by opening tetrameric ion channels such as inward rectifiers. It's not sleep-related, but cortical astrocytes release potassium and adenosine in order to accomplish this process as an autoregulatory response to increases in a cerebral "perfusion" gradient. Pharmaceutical induction of this process by drugs like doxazosin, papaverine and amyl (*) nitrites may impair the ability of the baroreceptor reflex to respond to septic shock. This process occurs when certain cells are hyperpolarized by EDHF and prostacyclin, which are activated by bradykinin. A phosphodiesterase that inhibits this process is blocked by sildenafil. This process occurs when protein kinase G causes smooth muscle relaxation after guanylyl cyclase is activated by endothelial nitric oxide. For 10 points, name this process of widening blood vessels.
