OBJECTIVE
The objective of this study is to explore the protective effect of an angiotensin receptor blocker (ARB) on local cardiovascular angiotensin II (AngII) and oxidative stress markers such as malondialdehyde (MDA), NADPH oxydase p47(phox), and 8-hydroxy-2'-deoxyguanosine/8-hydroxyguanosine
Our aim was to investigate the role played by endothelial nitric oxide (NO) during acute vascular response to hypoxia, as a modulator of both vascular tone (through guanylate cyclase (sGC) activation) and mitochondrial O2 consumption (through competitive inhibition of cytochrome-c-oxydase (CcO)).
Nocturnal periodic hypoxemia occurring in a 25-year-old Duchenne muscular dystrophy patient under NIPPV control was successfully treated with monoamine oxydase inhibitor (MAOI), safrazine hydrochloride. Five mg of safrazine hydrochloride was administered before sleep, and the periodic hypoxemia
Iron metabolism in mammals requires a complex and tightly regulated molecular network. The classical view of iron metabolism has been challenged over the past ten years by the discovery of several new proteins, mostly Fe (II) iron transporters, enzymes with ferro-oxydase (hephaestin or
Respiration and oxidative phosphorylation of the brain and hepatic mitochondria, as well as the activity of succinate dehydrogenase, succinate-cytochrome-c-reductase and cytochrome oxydase were studied in experimental hypoparathyrosis. Activated respiration and decreased effectiveness of the brain
The evolution of experimental myocardial infarction in the Rat with or without revascularization has been studied histochemically and histoenzymatically in 56 animals sacrified after 1, 6, 12, 24, 48 hrs and 7 days. Following permanent ischemis (14 animals), there appeared an extended transversal
Previous studies have shown that injection of D-galactose could result in senescent performances in animals, that injection of NaNO2 could cause ischaemia and hypoxia in many organs, and combined injection of D-galactose and NaNO2 make normal mice taking on senescent performances in a shorter
