This study was aimed to investigate effects of aqueous citric acid (CA) and ascorbic acid (AA) on lipid oxidation in comparison with effect of vacuum packaging in order to find better treatment to delay improper changes in the Persian sturgeon (Acipenser persicus) fillets during frozen storage due to lipid oxidation. In this study traditional packaging, vacuum packaging, ascorbic acid solutio...

the aim of the present study was to compare three reducing sugars (d-glucose, d-arabinose, d-mannose) with respect to the antioxidative activity characteristics of their caramelisation products (cps) prepared by monitoring uv-absorbance, browning intensity, ferric ion reducing capacity, fe2+ ion chelating activity as well as dpph radical scavenging activity. moreover, the effect of cps from d-g...

dpph radical-scavenging activity of the bene hull oil (bho), sesame oil (seo), rice bran oil (rbo), the oils' methanolic (ch3oh/h2o, 80:20 v/v) or hexane extracts, and their unsaponifiable matters fraction were measured and compared with each other. as a radical-scavenger, seo was significantly stronger than rbo and bho, respectively. unlike bho and rbo, the unsaponifiable (usm) fraction of the...

conclusions contrast-agent-induced nephropathic changes are more closely related to the magnitude of lipid peroxidation than protein oxidation. results compared with the control group, groups cin and n + cin had significantly higher urea and lhp levels (p < 0.05 and p < 0.001, respectively) and significantly lower cu, zn-sod activity and creatinine clearance (p < 0.05). there was no statistical...

OBJECTIVE: Oxidative stress is a serious complication in diabetic patients. Black tea and also sour tea contained some flavonoids with antioxidant properties and may be helpful in prevention of lipid oxidation. The aim of this study was to compare the effects of sour tea and black tea on in-vitro copper induced serum lipids oxidizability in diabetic patients. MATERIALS AND METHODS: In this se...

Objective: Diabetes is the most common metabolic disease. One of the most common problems in diabetic patients is atherosclerotic cardiovascular disease which induced by hyperlipidemia. Also there has been currently great interest in the potential contribution of oxidative stress in development of diabetes complications. The present study was performed to associate between lipid oxidizability a...

Dietary polyunsaturated fats and vitamin E are associated with reduced risk for atherosclerosis, but in smokers, they could promote lipid oxidation. Therefore, we examined the effects of a high polyunsaturated fat diet and vitamin E supplementation on measures of lipid oxidation in cigarette smokers. Ten subjects who smoked >1 pack of cigarettes per day were sequentially fed the following: a ba...

Human seminal plasma is a natural reservoir of antioxidants that protect spermatozoa from oxidative damages. There is evidence in literature supports the fact that impairments in seminal antioxidant and lipid per-oxidation status play important roles in the physiopathology of male infertility. Our present study forms the first one which was carried out in Tunisia. We evaluated the antioxidant s...
