Pathophysiological Reactivities of Nitric Oxide

The nitric oxide pathway in pre-eclampsia: pathophysiological implications.

Pre-eclampsia, one of the most significant health problems in human pregnancy, complicates approximately 6-8% of all gestations and is the leading cause of fetal growth retardation, infant morbidity and mortality, premature birth and maternal death. Recent research implicates free radicals in the pathophysiology of pre-eclampsia. This review covers the biochemistry of nitric oxide (NO) and poss...

[Role of nitric oxide in the control of the pulmonary circulation: physiological, pathophysiological, and therapeutic implications].

Nitric oxide (NO) is an endogenous vasoactive compound that contributes to pulmonary vascular homeostasis and is produced by three nitric oxide synthase (NOS) isoforms-neuronal NOS (nNOS); inducible NOS (iNOS); and endothelial NOS (eNOS)-all three of which are present in the lung. Studies using pharmacological inhibitors or knockout mice have shown that eNOS-derived NO plays an important role i...

Nitric Oxide Production and Nitric Oxide

Nitric oxide and the bioactivities

Nitric oxide (NO), previously known as Endothelium-Derived Relaxing Factor (EDRF) is involved in a wide range of physiological and pathophysiological mechanisms. It is synthesized endogenously by the enzymes Nitric Oxide Synthase (NOS) in specialized tissues from its precursor L-arginine, yielding L-citrulline as a byproduct. It is released by a family of isoenzymes, viz., the endothelial (eNOS...

Is Nitric Oxide a Hormone?

Nitric oxide (NO) is a simple ubiquitous signaling molecule and plays important roles in almost every biological system. Recent evidences suggest that NO may act as an endocrine molecule. The aim of this review is considering available literature on endocrine roles of NO and/or its metabolites, i.e. nitrite and nitrate. Existing data suggest the idea that NO is a hormone that after production i...
