Free radicals especially reactive oxygen metabolites can damage DNA, protein, enzymes, and membrane lipids. Lipid peroxidation in hepatocyte membrane may be involved in hepatic diseases. Antioxidants may inhibit this reaction. Due to oxidant-antioxidant imbalance, free radicals may cause destructive effects. For several years, scientists tried to find antioxidant compounds. In this study, the e...

The first aim of this study was to test whether there are changes in erythrocyte lipid peroxidation products and membrane fluidity during cardiac surgery involving cardiopulmonary bypass. Secondly, in vitro tests were performed to examine whether melatonin alters induced lipid peroxidation and reduced membrane fluidity in erythrocytes from these patients. Fifteen patients undergoing cardiac sur...

background: the association between lipid peroxidation biomarkers and adipocytokines is hypothesized in preeclampsia but little is known about it. objective: the present study was undertaken to determine the association of lipid peroxidation biomarkers measured by the levels of 8-isoprostane and malondialdehyde with adipocytokines leptin and adiponectin in maternal serum of preeclamptic women. ...

effects of n-3 or n-6 polyunsaturated fatty acids alone or in combination with vitamin e on male breeders’ fatty acid composition of spermatozoa, fertility and lipid peroxidation were studied. fish oil increased c22:6 n-3 and decreased c22:4 n-6 in the spermatozoa (p

objective(s) recent studies revealed the neuroprotective effects of epigallocatechin gallate (egcg) on a variety of neural injury .the purpose of this study was to determine the effects of egcg on the tissue lipid peroxidation after spinal cord injury (sci). materials and methods rats were randomly divided into four groups of 7 rats each as follows: sham-operated group, trauma group, and egcg-t...

Background: The lipid peroxides and their degradation products are highly toxic to spermatozoa and may play a major role in sperm dysfunction. The purpose of this study was to determine the level of lipid peroxidation as indicated by malondialdehyde (MDA) in the spermatozoa and seminal plasma of asthenozoospermic and normozoospermic males. In addition, correlation of lipid peroxidation with mot...

conclusions troxerutin may reduce the vascular complications and tissue injuries induced by chronic diabetes in rat aorta through increasing the activity of tissue antioxidant system and reducing the level of lipid peroxidation. materials and methods male wistar rats were randomly divided into four groups (n = 8/each): control, control plus troxerutin, diabetic and diabetic plus troxerutin. dia...

In the present study we have examined the influence of single spraying with simulated acid rain (pH 1.8) on the content of main lipid classes and their fatty acid composition in the thylakoid membranes of bean plants. Acid stress caused considerable changes in the investigated parameters. A decline in the content of linolenic acid, a highly unsatureted fatty acid which is an indicator of lipid ...
