the present study was carried out to examine the effects of a vitamin premix (vp) reduction or withdrawal from finisher diet (29-43 days) on performance, immuno-competence, and characteristics of leg bones and meat lipid oxidation of chickens fed on corn-soybean meal based diet. a total of 900 male broiler chickens (ross 308) were allocated to five treatment groups (0, 33%, 66%, 100% and 133% v...
conclusions the results of the present investigation suggest that sac could be used as a food supplement in the treatment of diabetes characterized by provoked antioxidant status, altered blood glucose, and hormones level. results the levels of glucose, cyp2e1 activity, thiobarbituric acid reactive substances (tbars), hydroperoxide, and ceruloplasmin were increased significantly; whereas, the l...
this research was carried out to assess the effect of drought stress on head branch dry weight, photosynthesis, essential oil yield and radical scavenging of rosemary (rosmarinus officinalis l.) in islamic azad university, shoushtar branch, iran during 2010-2011.the experiments were carried out using complete randomized block design with four replications and drought stress levels included cont...
Tumor cells generally display low lipid peroxidation. A low content of polyunsaturated fatty acids in membrane phospholipids is a possible cause of their decreased susceptibility to lipid peroxidation. To investigate the importance of substrate availability in eliciting lipid peroxidation and to study cell viability in conditions of stimulated lipid peroxidation, AH-130 hepatoma cells were enri...
The present work was carried out to study the involvement of lipid peroxidation in immobilization-induced damage of the rat lung Thirty-hour immobilization stress was found to result in a marked morphological alteration of the lung ultrastructure and in significant increases of both acid and alkaline phosphatase for immobilization times exceeding 12 and 24 hours respectively Also, increased con...
The ability of erythrocytes to resist lipid peroxidation may be a useful marker of antioxidant status in alcoholic patients, in whom depletion of dietary antioxidants may combine with increased production of free radicals to produce liver damage. There are conflicting reports, however, on the resistance of erythrocytes from alcoholic patients to lipid peroxidation. This study examined the relat...
BACKGROUND/AIM Sonodynamic cancer therapy is based on the preferential uptake and/or retention of a sonosensitizing drug (sonosensitizer) in tumor tissues and subsequent activation of the drug by ultrasound irradiation. In the present study, we investigated the participation of lipid peroxidation in the mechanism of the sonodynamically-induced antitumor effect with functionalized fullerenes, su...
Synthesis and Photoirradiation of Isomeric Ethylchrysenes by UVA Light Leading to Lipid Peroxidation
Polycyclic aromatic hydrocarbons (PAHs) are widespread genotoxic environmental pollutants. We have recently demonstrated that photoirradiation of PAHs leads to cytotoxicity, DNA damage, and induction of lipid peroxidation. In this paper we report the synthesis of all the six isomeric ethylchrysenes and the study of light-induced lipid peroxidation by these ethylchrysenes. 5-Ethylchrysene was sy...

We initially compared lipid peroxidation profiles in tobacco (Nicotiana tabacum) leaves during different cell death events. An upstream oxylipin assay was used to discriminate reactive oxygen species (ROS)-mediated lipid peroxidation from 9- and 13-lipoxygenase (LOX)-dependent lipid peroxidation. Free radical-mediated membrane peroxidation was measured during H(2)O(2)-dependent cell death in le...
