Superoxide Anion Chemistry-Its Role at the Core of the Innate Immunity. [PDF]

open access: yesInt J Mol Sci, 2023
Classically, superoxide anion O2•− and reactive oxygen species ROS play a dual role. At the physiological balance level, they are a by-product of O2 reduction, necessary for cell signalling, and at the pathological level they are considered harmful, as ...

The superoxide anion donor, potassium superoxide, induces pain and inflammation in mice through production of reactive oxygen species and cyclooxygenase-2 [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2015
It is currently accepted that superoxide anion (O2•−) is an important mediator in pain and inflammation. The role of superoxide anion in pain and inflammation has been mainly determined indirectly by modulating its production and inactivation.

Effects of superoxide anion attack on the lipoprotein HDL. [PDF]

open access: yesMol Cell Biochem, 2023
AbstractHigh-density lipoprotein (HDL) is an anti-atherosclerotic lipoprotein. Thanks to the activity of apolipoprotein ApoA1, the principal protein component of HDL, this last is responsible for converting cholesterol into ester form and transporting excessive cholesterol to the liver (“reverse cholesterol transport” RCT). When HDL undergoes oxidation,

Enhancement of platelet function by superoxide anion. [PDF]

open access: bronzeJournal of Clinical Investigation, 1977
During the aerobic conversion of xanthine to uric acid by xanthine oxidase, superoxide anion and hydrogen peroxide are produced along with the hydroxyl radical. Our studies demonstrate that washed human platelets incubated with xanthine and xanthine oxidase aggregated and released [14C]serotonin.

Superoxide Anion Production by the Spermatozoa of Men with Varicocele: Relationship with Varicocele Grade and Semen Parameters [PDF]

open access: yesThe World Journal of Men's Health, 2018
Purpose: To investigate the pathophysiological role of superoxide anion and total reactive oxygen species (ROS) production by the spermatozoa of men with varicocele and its relationship with varicocele grade and semen parameters.

Effects of a high-fat diet on superoxide anion generation and membrane fluidity in liver mitochondria in rats [PDF]

open access: yesJournal of the International Society of Sports Nutrition, 2018
Background Obesity is a primary factor of lifestyle-related diseases, and the age of its onset has decreased. The reactive oxygen species (ROS), the superoxide anion, is generated in the mitochondrial electron transport chain and the damage it induces in

Superoxide anion production and superoxide dismutase and catalase activities in Coxiella burnetii [PDF]

open access: bronzeJournal of Bacteriology, 1983
Coxiella burnetii was examined for superoxide anion (O2-) production and superoxide dismutase and catalase activities. The organism generated O2- at pH 4.5 but not at pH 7.4. The rickettsia displayed superoxide dismutase activity distinguishable from that of the host cell (L-929 mouse fibroblast).
