Hyperhomocysteinemia decreases GSH peroxidase activity leading to the prevalence of GSSG on GSH with the GSH/GSSG impaired ratio causing some common cardiovascular and neurodegenerative disorders (159)
The World Anti-Doping Agency has banned these compounds, noting they lack approval from any health regulatory authority and are intended only as research tools
discovered that insomnia is associated with significant changes in the structure and function of gut microbiota, showing reduced diversity (both -diversity and -diversity) and altered microbial interactions in individuals with insomnia compared to healthy controls [213]
In the following section, we summarize (i) the sources of oxidants in healthy RBCs, (ii) the antioxidant systems, including (ii.a) antioxidant molecules and their redox couples, such as reduced and oxidized glutathione (GSH/GSSG), ascorbate/dehydroascorbate (vitamin C), and -tocopherol (vitamin E), (ii.b) the sources of reducing equivalents such as nicotinamide adenine dinucleotide (NADH) and nicotinamide adenine dinucleotide phosphate (NADPH), and (ii.c) the antioxidant enzymes such as superoxide dismutase (SOD), catalase (Cat), glutathione peroxidase (GPx), and peroxiredoxin 2 (Prx2)
