Role of the soluble epoxide hydrolase and cytochrome P450-derived epoxyeicosatrienoic acids in hypoxic pulmonary vasoconstriction and hypoxia-induced pulmonary vascular remodelling [PDF]

, 2009
Hypoxic pulmonary vasoconstriction (HPV) redistributes pulmonary blood flow from areas of low oxygen partial pressure to areas of normal or relativity high oxygen availability, thus optimising the matching of perfusion to ventilation and preventing ...
