Reactive oxygen species in spermatozoa: methods for monitoring and significance for the origins of genetic disease and infertility [PDF]
Reproductive Biology and Endocrinology, 2005 Human spermatozoa generate low levels of reactive oxygen species in order to stimulate key events, such as tyrosine phosphorylation, associated with sperm capacitation. However, if the generation of these potentially pernicious oxygen metabolites becomes

Regulation of inducible peroxide stress responses [PDF]
Molecular Microbiology, 2002 SummaryBacteria adapt to the presence of reactive oxygen species (ROS) by increasing the expression of detoxification enzymes and protein and DNA repair functions. These responses are co‐ordinated by transcription factors that regulate target genes in response to ROS. We compare three classes of peroxide‐sensing regulators: OxyR, PerR and OhrR.

Cold stress-induced lipid peroxidation and non-enzymatic antioxidant defense in tissues of the common Indian toad, Bufo melanostictus [PDF]
Archives of Biological Sciences, 2014 The aim of this study was to investigate the effect of exposure to short-term cold stress (30 min at 0-4°C) on lipid peroxidation and the non-enzymatic antioxidant defense system in liver, kidney and brain tissues of an ectothermic animal, the ...

Oxidant Stress and Lipid Peroxidation in Acetaminophen Hepatotoxicity [PDF]
Reactive Oxygen Species, 2018 Acetaminophen (APAP) overdose is the most frequent cause of liver injury and acute liver failure in many western countries. The mechanism of APAP-induced hepatocyte necrosis has been investigated extensively. The formation of a reactive metabolite and its binding to cellular proteins was initially thought to be responsible for cell death.
