the antioxidant activities of tbhq, bht and tocopherol mixtures at different concentrations (0, 100, 200, 400 mg/kg) have been evaluated by the application of differential scanning calorimetry (dsc) and rancimat apparatus. rancimat apparatus that measures the secondary oxidation products was set at 110 ⁰c with an air flow of 18-20 l/h to measure the induction period (ip) of the samples. the dsc...

background: the aim of this study was to investigate the effects of leishmania major infection on the induction of oxidative stress in skin and lung of female mice. methods: balb/c mice were randomly divided into the control and experi-mental groups. the experimental groups were subcutaneously infected with in-oculums promastigotes of l. major . the animals were sacrificed at 20, 40, 60, 90 and...

abstract: the commercial development of food products originated from the plants as sources of antioxidants to increase the health benefit and stabilize the food is of current interest. this study was aimed at obtaining dill extract using cold solvent method by three solvents, (methanol, acetone, and hexane) and examining the antioxidant potency and determining the oxidative stability of sunflo...

inducible nitric oxide synthase (inos) gene expresses a calcium calmudolin-independent enzyme which can catalyse no production from l-arginine. the induction of inos activity has been demonstrated in a wide variety of cell types under stimulation with cytokines and lipopoly saccharide (lps). previous studies indicated that all nitric oxide synthases (nos) activated in human umbilical vein endot...

background: it has been proposed that oxidative stress may contribute to the development of testicular abnormalities in diabetes. morus alba leaf extract (mae) has hypoglycemic and antioxidant properties. we, therefore, explored the impact of the administration of mae on steroidogenesis in diabetic rats. methods: to address this hypothesis, we measured the serum level of glucose, insulin, and f...

the present work is aimed to find a new and efficient type of antioxidants for polypropylene. hence, effects of 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one, generally known as thymolphthalein, on thermo-oxidative stability of polypropylene in solid and melt states were evaluated and compared with those of songnox 1010, an efficient commercially used antioxidant for the po...

objective: oxidative stress that damages proteins result in aging and age related diseases. the aim of this study is to determine the effect of tocotrienol rich fraction (trf) on the expression of proteins in oxidative stress-induced caenohabditis elegans (c.elegans) which has homologous genes to humans. methods: the worms were treated with trf prior to, after and continuously in separate group...
