Neonatal and maternal concentrations of hydroxil radical and total antioxidant system: protective role of placenta against fetal oxidative stress.
BACKGROUND: Reactive oxygen species (ROS) may cause peroxydation of lipids, proteins and deoxyribonucleic acids with subsequent cell damage. The hydroxyl radical (OH*) represents a measure of global oxidative stress. Hydroxyl radicals are short-lived; they form an important part of radical chemistry nonetheless. The measure of total ant.....
