Superoxide Anion Chemistry—Its Role at the Core of the Innate Immunity

International Journal of Molecular Sciences, 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 ...

Association Between Superoxide Dismutase Isoenzyme Gene Expression and Total Antioxidant Status in Patients with an End-Stage Renal Disease

Balkan Medical Journal, 2018
Background: Chronic renal failure, particularly end-stage renal disease, is a serious health problem associated with a high mortality rate. Uremic syndrome leads to increased oxidative stress, inflammation, and dyslipidemia.

Cu,Zn superoxide dismutase genes in Tribolium castaneum: evolution, molecular characterisation and gene expression during immune priming. [PDF]

, 2017
The production of reactive oxygen species (ROS) is a normal consequence of the aerobic cell metabolism. Despite their high and potentially detrimental reactivity with various biomolecules, the endogenous production of ROS is a vital part of physiological,

Manganese Superoxide Dismutase Dysfunction and the Pathogenesis of Kidney Disease

Frontiers in Physiology, 2020
The mitochondria are a major source of reactive oxygen species (ROS). Superoxide anion (O2•–) is produced by the process of oxidative phosphorylation associated with glucose, amino acid, and fatty acid metabolism, resulting in the production of adenosine

Evaluación de la toxicidad de cobre en suelos a través de biomarcadores de estrés oxidativo en eisenia foetida Assessment of copper toxicity in soils using biomarkers of oxidative stress in eisenia foetida

Química Nova, 2010
Copper toxicity in soil was evaluated using biomarkers of oxidative stress (catalase enzyme activity, superoxide dismutase and lipid peroxidation) in the earthworm Eisenia foetida. Agricultural topsoils from mining areas of the Aconcagua river basin were

Literature-based discovery of diabetes- and ROS-related targets [PDF]

, 2010
Background Reactive oxygen species (ROS) are known mediators of cellular damage in multiple diseases including diabetic complications. Despite its importance, no comprehensive database is currently available for the genes associated with ROS.

Manganese Superoxide Dismutase Overexpression Attenuates MPTP Toxicity

Neurobiology of Disease, 1998
There is substantial evidence implicating mitochondrial dysfunction and free radical generation in the neurotoxicity of MPTP. Manganese superoxide dismutase (MnSOD) is the primary antioxidant enzyme protecting against superoxide radicals produced within ...

Catalase, glutathione peroxidase, metabolic syndrome, superoxide dismutase

Majalah Kedokteran Bandung, 2012
Labor pain is part of a normal process, which often causes physiological and psychological stress to mother. These stress have impact to both mother and fetus. Largely (90%) labor comes with pain and in some cases severe pain.
