Deciphering the catalytic mechanism of superoxide dismutase activity of carbon dot nanozyme
Nature Communications, 2023 Superoxide dismutase (SOD) nanozymes show mitigating effect on oxidative stress-related diseases, but are limited by their modest activity. Here, the authors report a carbon dot SOD nanozyme with catalytic activity matching natural enzymes and unveil its

Brazilian Journal of Biology, 2021 The cold storage of milt implies potentials alterations in its quality because the storage generates as main process, free radicals that produce spermatozoa membrane lipids damage with the consequent motility and fertilising capacity disruptions.

Anti-inflammatory effects of secondary metabolites of marine Pseudomonas sp. in human neutrophils are through inhibiting P38 MAPK, JNK, and calcium pathways. [PDF]
PLoS ONE, 2014 Activated neutrophils play a significant role in the pathogenesis of many inflammatory diseases. The metabolites of marine microorganisms are increasingly employed as sources for developing new drugs; however, very few marine drugs have been studied in ...

Microsomal superoxide anion production and NADPH-oxidation in a series of 22 aziridinylbenzoquinones [PDF]
, 1989 Several 2,5-bis(1-aziridinyl)-1,4-benzoquinones (BABQs) can be activated to alkylating species by reduction of the quinone moiety. On the other hand, cytotoxicity of these compounds can be induced by redox cycling.

Ursodeoxycholic acid and superoxide anion
World Journal of Gastroenterology, 2005 To investigate the ability of ursodeoxycholic acid (UDCA) to scavenge superoxide anion (O(2)(-)).We assessed the ability of UDCA to scavenge (O(2)(-)) generated by xanthine-xanthine oxidase (X-XO) in a cell-free system and its effect on the rate of O(2)(-)-induced ascorbic acid (AA) oxidation in hepatic post-mitochondrial supernatants.UDCA at a ...

Lipid peroxidation is a nonparenchymal cell event with reperfusion after prolonged liver ischemia [PDF]
, 1990 A proposed mechanism for irreversible ischemic liver damage has been peroxidation of membrane phospholipids by free radicals. However, the hepatocyte is laden with enzymes which are antioxidants and, therefore, ought to be relatively resistant to ...

Superoxide anions in paraventricular nucleus modulate adipose afferent reflex and sympathetic activity in rats. [PDF]
PLoS ONE, 2013 Adipose afferent reflex (AAR) is a sympatho-excitatory reflex induced by chemical stimulation of white adipose tissue (WAT). Ionotropic glutamate receptors including NMDA receptors (NMDAR) and non-NMDA receptors (non-NMDAR) in paraventricular nucleus ...
