The reactive species of oxygen not neutralized by antioxidant defenses react with proteins, DNA, RNA, and lipids of cellular membranes giving rise to blocking various steps of cellular metabolism and to mitochondrial dysfunction, all of which lead to cellular energy failure. An increment of nitric oxide NO production occurs at the same time that inflammatory process.

Translation of «nitrato» into 25 languages

NO produced in excess reacts with superoxide anion giving rise to the formation of peroxynitrite ONOO- , a highly reactive species with capacity for nitridation of tyrosine residues, for oxidation of lipids and critical enzymes of the intermediary metabolism, and for breaking DNA chains. ONOO- also oxidizes and give rise to a depletion of endogenous antioxidants, as ascorbate, glutation, and superoxide dismutase.

The presence of ONOO- and other reactive species from nitrogen as nitrogen dioxide in conjunction with the increase of oxidative stress, perpetuates the inflammatory process through various mechanisms e. The progress described contributes a new importance to oxidative stress and to nitridative stress in the knowledge of the pathogenesis of sepsis, and makes it possible to understand the physiopathological bases of cellular dysfunction in sepsis..

Aspects of the seminar which are highlighted include the preservation of traditional materials such as daguerreotypes, glass plate negatives, and movies on cellulose nitrate stock. First milk beestings of cows fed on a nitrate nitrogen diet had lower concentration of carotenes, retinol and gamma-globulin. Saltpeter is potassium nitrate , which was indeed used for curing meat.
