Background: Recent studies have shown that non-alcoholic fatty liver disease (NAFLD) is associated with increased carotid intima-media thickness as a reliable marker of early atherosclerosis, but possible direct relationships between NAFLD and carotid artery atherosclerosis is unknown. Therefore, the aim of this study was to investigate serum paraoxonase and arylesterase activities (PON1) along...
Methyl linoleate hydroperoxides (MLHPO), a model for lipid hydroperoxides, decreased fungicidal activity of human polymorphonuclear leukocytes (PMN) for fungi of Candida albicans. When PMN was cultured with MLHPO, phagocytosis to fungi was depressed. Degree of the depression was dependent on the concentration of MLHPO and the treatment time with MLHPO. These findings indicate that phagocytic ac...

Ionizing radiation (IR) triggers mitochondrial overproduction of H2O2 and accumulation of lipid hydroperoxides leading to the induction of apoptotic and necroptotic cell death pathways. Given the high catalytic efficiency of the seleno-enzyme glutathione peroxidase (Gpx) toward reduction of lipid hydroperoxides and H2O2, we tested the potential of mitochondria-targeted derivatives of ebselen to...
Lipid oxidation has been implicated in the pathogenesis of many diseases. Lipids are oxidized in vivo by several different oxidants to give diverse products, in general lipid hydroperoxides as the major primary product. In the present study, the production of lipid hydroperoxides in the oxidation of mouse plasma induced by multiple oxidants was measured using diphenyl-1-pyrenylphosphine (DPPP) ...
The antioxidant activity of capsaicin, as compared to BHT and melatonin, was determined by the direct measurement of lipid hydroperoxides formed upon linoleic acid autoxidation initiated by AIBN. The formation of four isomeric lipid hydroperoxides was detected after reverse-phase HPLC separation. Data from three detectors, UV absorption, glassy carbon electrode electrochemical detection, and po...
BACKGROUND Our objective is to determine the activity of the antioxidant defense system at admission in patients with early onset first psychotic episodes compared with a control group. METHODS Total antioxidant status (TAS) and lipid peroxidation (LOOH) were determined in plasma. Enzyme activities and total glutathione levels were determined in erythrocytes in 102 children and adolescents wi...
High-density lipoprotein (HDL) has been proposed as the principal carrier of hydroperoxides in plasma, based upon data gathered with an HPLC-chemiluminescence technique. To test this hypothesis we have measured total lipid hydroperoxides in native plasma using the ferrous oxidation in Xylenol Orange (FOX) assay and then fractionated plasma into very-low-density lipoprotein (LDL) and HDL fractio...
