As index of oxidative damage, we evaluated lipid peroxidation in kidney, liver, and skeletal muscle, detecting a significant rise...

... in adipose tissue, and (iii) hepatic lipid peroxidation and protein oxidation indexes. It is concluded that a marked enhancement in LCPUFA n -6/ n -3 ratio occurs in the liver of NAFLD patients, a condition that may favour lipid synthesis over oxidation and secretion, thereby leading to steatosis. Depletion...

...Annika SMEDMAN; Bengt VESSBY; Samar BASU We have found previously that supplementation with conjugated linoleic acid (CLA) induces lipid peroxidation and inflammation in humans as indicated by an increase of 8-iso-prostaglandin F 2α (PGF 2α ) and 15-keto-dihydro-PGF 2α respectively. The present...

...) there was no competition for uptake between phytanic acid and α-tocopherol, and (d) the incorporation of phytanic acid did not increase the susceptibility of membranes to lipid peroxidation in vitro . These results obtained with cultured retinal cells suggest that the molecular distortion hypothesis, but not the anti...

... was related to enhanced exercise-induced mobilization/oxidation of blood lipids due to a selective increase in o 2max ( P < 0.05 compared with normoxic group). We conclude that lipid peroxidation induced by acute exercise (1) increases during hypoxia; (2) is not regulated exclusively by a mass action...

... 1 month of daily CLA intake (4.2 g/day) as compared with the control group. The lipid peroxidation parameters had returned to their basal levels at 2 weeks after the cessation of CLA intake, and remained at the same levels for a further 2 weeks until the end of the study. CLA had no effect on serum...

Plasma total antioxidant status and malondialdehyde concentration were measured during the first 11 days of life in 25 infants to determine whether increased lipid peroxidation is associated with low extracellular antioxidant status. In a second group of infants, total...

The ability of albumin to bind iron and to prevent iron-dependent lipid peroxidation in vitro was investigated using liposomes and a rat brain homogenate system. 4. The iron-binding capacity of albumin was found...
