Objective(s):Sub-health has been described as a chronic condition of unexplained deteriorated physiological function, which falls between health and illness. In the present study, we evaluated the effects of Lycium barbarum polysaccharide (LBP), a polysaccharide fraction purified from Lycium barbarum (L. barbarum) on the sub-health mice. Materials and Methods:The sub-health model mice were buil...

Free radicals induced by traumatic brain injury have deleterious effects on the function and antioxidant vitamin levels of several organ systems including the brain. Melatonin possesses antioxidant effect on the brain by maintaining antioxidant enzyme and vitamin levels. We investigated the effects of melatonin on antioxidant ability in the cerebral cortex and blood of traumatic brain injury ra...

      In the present study, an oxidative conversion of non-fluorescent dichlorofluoroscein (LDCF) to fluorescent dichlorofluoroscein (DCF) was used for detection of antioxidant properties of plant extracts. The rate of the reaction was followed by monitoring the formation of DCF as a function of time. The antioxidant assay was carried out for different concentrations of gallic acid, Salvia ...

Background Any factor like diabetes that changes the oxidant/antioxidant balance in favor of oxidants could possibly disrupt the physiologic function of ovaries. So, we have investigated the effect of vitamin E and Se supplements on antioxidant defense in ovaries of diabetic rats with focus on Xanthine dehydrogenase/oxidase (XDH/XO) and Aldehyde oxidase (AO) activities. MaterialsAndMethods This...

objective(s) nonenzymatic glycosylation (glycation) occurs in many macromolecules in aging and diabetes due to exposure of biomolecules to high level of glucose. glycation can changes function, activities and structure of many biomolecules. considering this important role of transferrin (trf) in iron transport and antioxidant activity in plasma this study was carried out to investigate the effe...

neurotoxicity following cerebral ischemia-reperfusion. Accumulation of ROS, particularly superoxide anion (O ) and hydrogen peroxide (H2O2) causes damage to membrane phospholipids, proteins and DNA. Under normal circumstances, these oxidant species can be effectively scavenged by antioxidant enzymes, namely superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPX). In mammalian SOD...

Novel mixed antioxidants composed of antioxidant IPPD and lanthanum (La) complex were added as a filler to form natural rubber (NR) composites. By mechanical testing, Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR) and thermogravimetric analysis (TGA), a string of data, including the mechanical properties, the variation of internal groups and the thermal and...

Objective(s): The effect of propolis collected in Morocco on blood glucose, lipid profile, liver enzymes, and kidney function was investigated in control and diabetic rats.  Materials and Methods: Antioxidant activity of propolis was evaluated with the use of DPPH, 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS•+), ferric ...
