Reduced serum non-enzymatic antioxidant defense and increased lipid peroxidation in schizophrenic patients on a hypocaloric diet
INTRODUCTION Growing evidence suggests that oxidative stress (OS) may be associated with the pathophysiology underlying schizophrenia (SZ). Some studies indicate that nutritional supplements offer protection from OS, but there is no data about the effect of a hypocaloric diet on OS in this population. Therefore, we aimed to study the effect of a hypocaloric dietary intervention on OS in subject...
متن کاملAntioxidant activity and lipid peroxidation in preeclampsia.
BACKGROUND Epidemiologic studies demonstrate a relation between preeclampsia and an increased risk of future maternal coronary heart disease. The pathophysiology of the underlying mechanism is unknown. Disorders of lipoprotein metabolism may contribute to endothelial dysfunction. Oxidative stress and decreased antioxidant defense enhances free radical-mediated membrane lipid peroxidation and po...
متن کاملtoxic effects of cadmium on antioxidant defense systems and lipid peroxidation in acipenser persicus (borodin, 1897)
cadmium is considered as a common residue in water and sediments which could readily enter aquatic organisms. the aim of this study was to evaluate the time- and concentration-dependent changes in antioxidant enzymes (sod and cat) activities as well as concentration of mda as a bi- product of lipid peroxidation in the liver of persian sturgeon, acipenser persicus , following cdcl 2 exposure at ...
متن کاملAntioxidant defense system and lipid peroxidation in patients with skeletal fluorosis and in fluoride-intoxicated rabbits.
Fluorosis is a serious public health problem in many parts of the world where drinking water contains more than 1 ppm of fluoride. The main manifestations of skeletal fluorosis are crippling bone deformities, spinal compressions, and restricted movements of joints. Although fluorosis is irreversible, it could be prevented by appropriate and timely intervention through understanding the process ...
متن کاملChanges in maternal lipid peroxidation levels and antioxidant enzymatic activities before and after delivery.
OBJECTIVE Our goal was to characterize the changes in maternal lipid peroxidation levels and antioxidant enzymatic activities before and after delivery. METHODS Predelivery and 1, 24, and 48 hours post-partum plasma concentrations of malondialdehyde, erythrocyte enzyme superoxide dismutase, glutathione peroxidase and catalase were measured in uncomplicated pregnancies. RESULTS Malondialdehy...
