Activity of antioxidant enzymes in the skin during surgical wounds

Bulletin of Experimental Biology and Medicine, 2006
Full-thickness skin wounds (460 mm(2)) in rats were associated with increased blood chemiluminescence and neutrophil infiltration of the wound tissue and surrounding skin (recorded by myeloperoxidase activity). Activities of glutathione peroxidase and glutathione S-transferase in the skin and wound tissue increased on days 4 and 8.

Influences of chlorpyrifos on antioxidant enzyme activities of Nilaparvata lugens

Ecotoxicology and Environmental Safety, 2013
The brown planthoppers (Nilaparvata lugens, BPH) resistant to chlorpyrifos were selected in laboratory for eight generations. In the full course, the successive changes of activities of SOD, CAT and POD were analyzed. The analyses revealed that increasing of LD50 value was parallel to increasing of SOD, CAT, and POD, all of which increased gradually ...

GaSex Nanoparticles Modulate Neutrophil Function and Mitigate NET‐Driven Osteogenic Impairment in Osteomyelitis Therapy

Advanced Materials, EarlyView.
Neutrophil extracellular traps (NETs) emerge as a critical repair‐limiting factor in osteomyelitis, driving osteoblast mitochondrial dysfunction and excessive PINK1/Parkin‐mediated mitophagy. Gallium–selenium nanoparticles (GaSex) scavenge reactive oxygen species, redirect neutrophils from NETosis toward bactericidal phagocytosis, eliminate methicillin‐
