Background and Objectives: Since Yellow Horned Poppy (Glaucium flavum) has antioxidative effects, this study was conducted to determine its effect on some antioxidative enzymes of liver and kidney in Alloxan induced diabetic rats. Materials and Methods: In this experimental study, 40 adult male Wistar rats were randomly divided into 5 groups of 8 including: control, Diabetic, Diabetic treated...
The present study aimed to evaluate the effectiveness of three complex dietary candidate probiotics (LDJ, LAC, and LJD) composing different probiotic combinations on growth performance, digestive enzyme activities, antioxidant parameters, intestinal microbiota in koi carp (Cyprinus carpio var. koi). After a 60-days feeding trial, samples from control groups were obtained analyzed. results sugge...
Abiotic stresses such as drought, heat or salinity are major causes of yield loss worldwide. Recent studies have revealed that the acclimation of plants to a combination of different environmental stresses is unique and therefore cannot be directly deduced from studying the response of plants to each of the different stresses applied individually. The efficient detoxification of reactive oxygen...
Objectives: We hypothesize that enzymatic antioxidants are significant contributors to antioxidant status in gestational diabetes (GDM) through scavenging of free radicals. Methods: We evaluated total antioxidant activity and the activities of two major physiological antioxidant enzymes: glutathione peroxidase (GPX) and superoxide dismutase (SOD) in peripheral blood of 22 pregnant Kuwaiti women...
Mercury (II) is a highly toxic metal which induced oxidative stress in the living organism. In the present study we examined the effect of S-Allyl cysteine (SAC) against the mercuric chloride (Hgcl2) intoxicated in albino rat model. The animals were treated with sub-leathal dose of mercuric chloride (1.23 mg/kg body wt) for 7 days. After scheduled treatetment the animals were decapitated and wh...
the geopolitics of afghanistan after september 11, 2001, and its impact on iranian national security
abstract u.s. attack to afghanistan after 9/11 provided opportunities for us who tried to become the dominant power after collapse of ussr and bipolar world. thinkers like fukuyama believed american liberal democrats thought would be universally accepted without resistances. liberal democracy is the best and final model of governance; in this regard, united state has moral responsibilities for...
Background: Parkinson's disease (PD) is a neuropathologic disorder caused by dopaminergic neurons degeneration in the dense part of the substantia nigra. Objective: The present study, designed to evaluate the effect of hydroalcoholic extract of thyme on malondialdehyde (MDA), thiol, and glutathione peroxidase (GPX) concentration in the PD induced by 6-hydroxydopamine in an animal model. Methods...
Reactive oxygen species (ROS) are harmful to living organisms due to the potential oxidation of membranes, DNA, proteins, and carbohydrates. Freezing injury has been shown to involve the attack of ROS. Antioxidant enzymes can protect plant cells from oxidative stress imposed by freezing injury, therefore, cold acclimation may involve an increase in the expression of antioxidant enzymes. In this...
Cutaneous squamous cell carcinomas (CSCC) are a common malignancy of keratinocytes that arise in sites of the skin exposed to excessive UV radiation. In the present study, we show that human SCC cell lines, preneoplastic solar keratoses (SK), and CSCC are associated with perturbations in glutathione peroxidase (GPX) activity and peroxide levels. Specifically, we found that two of three SKs and ...
background: there are studies that indicated dyshomeostasis of oxidant/antioxidant and trace elements in breast cancer patients, but the data regarding the status of these parameters in various stages of breast cancer are limited. the aim of this study was to highlight the status of these biochemical factors in various stages of breast cancer. methods: fifty-eight breast cancers patients partic...
