[Oxidation of sulfur-containing substrates by aboriginal and experimentally designed microbial communities].

Prikl. Biokhim. Mikrobiol. 48(6) , 640-5, (2012)

Aboriginal and experimental (constructed of pure microbial cultures) communities of acidophilic chemolithotrophs have been studied. The oxidation of elemental sulfur, sodium thiosulfate, and potassium...

Role of renin-angiotensin system in activation of macrophages by modified lipoproteins.

Am. J. Physiol. Heart Circ. Physiol. 305(9) , H1309-20, (2013)

Angiotensin II favors the development of atherosclerosis. Our goal was to determine if foam cell formation increases angiotensin II generation by the endogenous renin-angiotensin system (RAS) and if e...
