The present study was undertaken to evaluate the effect of oxidative damage due to excessive protein diet on pancreas function in mice. For this purpose, thirty male (C57BL/6J) mice were randomly divided into three groups and fed on different diets as follows: group 1 was fed on a normal diet, group 2 was fed on an excessive protein diet and group 3 was fed on an excessive protein diet suppleme...

the aim of this investigation was to assess the effect of different antioxidants on the motility andmembrane integrity of the ram semen during storage at 5ºc for 0, 12, 24, 48 and 72 hrs after collection anddilution. a total of 57 ejaculates from 12 bakhtiary rams was collected by artificial vagina and were extended1 : 3 with egg yolk-citrate buffer, which was containing one of the following an...

The effect of the presence surfactant micelles and mode incorporation (pre-homogenization or post-homogenization) on antioxidant efficiency a homologous series n-alkyl gallates phenolipids (G0, G3, G8, G12 G16) was investigated in oil-in-water nanoemulsions. In both absence micelles, G16 were best antioxidants. modulated by micelles. G8 had higher when incorporated pre-homogenization, suggestin...

The gauge coupling constant unification at the low (O(TeV)) scale can be obtained just in four dimensions, without help of the power like renormalization group evolution in extra dimensions, due to the presence of some extra particle states at intermediate scales. We show explicit examples of such extra states in the range of 100 GeV – 1 TeV which can be easily observed on future colliders and ...

normal 0 false false false microsoftinternetexplorer4 the present study was carried out to determine the effect of hydroalcoholic extract of tylophora indica (heti) on experimentally-induced myocardial infarction (mi) in rats. albino rats were treated with heti at doses of 100 mg/kg, (heti-100) or 200 mg/kg (heti-200) and propranolol 10 mg/kg (pro-10) for 30 days orally. mi was induced by subcu...

spermatozoa generate reactive oxygen species (ros) in physiological amounts which play a role in sperm functions during sperm capacitation acrosome reaction (ar) and oocyte fusion. in addition damaged sperm are likely to be the source of ros. the most important ros produced by human sperm are hydrogen peroxide superoxide anion and hydroxyl radicals. besides human seminal plasma and sperm posses...

The balance between oxidation and antioxidation is believed to be critical in maintaining healthy biological systems. Under physiological conditions, the human antioxidative defense system including e.g., superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione (GSH) and others, allows the elimination of excess reactive oxygen species (ROS) including, among others s...

BACKGROUND Dietary questionnaire studies have suggested that patients with oesophageal adenocarcinoma are deficient in antioxidants. It is not known whether the same holds true for patients with the precursor lesion, Barrett's oesophagus. AIMS To evaluate the hypothesis that patients with Barrett's oesophagus are deficient in antioxidants compared with patients without evidence of Barrett's o...

In this study we investigated the effects of Caesalpinia decapetala (CD) extracts on lipid oxidation in ground beef patties. Plant extracts and butylated hydroxytoluene (BHT) were individually added to patties at both 0.1% and 0.5% (w/w) concentrations. We assessed the antioxidant efficacy of CD by the ferric reducing antioxidant power (FRAP) assay and evaluated their potential as natural antio...
