the antioxidant properties and total phenols’ content of 80% methanol, acetone and water extracts of olive leaves procured through microwave assisted extraction (mae) were examined. two varieties of olive namely: cronaiky and roghani were the ones studied. various experimental models were employed for antioxidant activity evaluation of the extracts. the results revealed the highest phenolic con...

The present study investigated the antilipoperoixdative and antioxidant effect of morin in normal and streptozotocin-induced diabetic Wistar rats. Diabetes as induced in rats by an intraperitoneal injection of streptozotocin. Morin was orally administered to normal and diabetic rats for a period of 45 days. In diabetic rats, thiobarbituric acid reactive substances and lipid hydroperoxides were ...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an enzymopathy in which reduced NADPH concentrations are not maintained, resulting in oxidative damage. We evaluated G6PD activity, oxidative stress levels and Trolox equivalent antioxidant capacity in individuals with the A-(202G>A) mutation for G6PD deficiency. Five hundred and forty-four peripheral blood samples were screened for G6PD de...

The molecular mechanisms of laser-induced changes in the cell structure and function are not well known. The authors examined the effects of low-power laser irradiation on unnucleated pig blood platelets. The obtained results showed that laser irradiation (1-5 J) caused in blood platelets lipid peroxidation (measured as thiobarbituric acid reactive substances) and superoxide anion generation, c...

The aim of this work was to compare the methods of malondialdehyde detection, as the main secondary product of the lipid peroxidation process, in meat and meat products. Malondialdehyde measurements were performed by two modified methods, the 2-thiobarbituric acid spectrophotometric method and the reverse-phase high-performance liquid chromatography in raw, mechanically-deboned chicken meat and...

The results of this study indicate that when human VLDL or LDL is prepared under conditions allowing oxidation, such oxidation renders the molecular complexes highly toxic to human skin fibroblasts growing in culture. The cytotoxicity can be predicted by assaying for the presence of thiobarbituric acid-reacting substances on the lipoprotein. However, malondialdehyde, which reacts with thiobarbi...

The thiobarbiturates differ from other barbiturates in having a sulfur atom to replace the carbonyl oxygen at the C-2 position. The drug 2-thiobarbituric acid was soluble in 95% ethanol and 5% water for sensitive detection and measurement. All samples were examined at 340 nanometer wavelength. An ultraviolet-visible instrument with one centimeter glass cuvettes was suitable for this assay. The ...

BACKGROUND The product quality of curry is determined by the food animal source, raw materials and the method of processing. Moreover the scientific information on processing and quality of traditional buffalo meat curry from different groups of buffaloes is not available. This study was undertaken to develop processed curry from different buffalo groups and to compare its quality during storag...
