Calendula officinalis (Family Compositae) flowers are recognized as safe substance for food use by Food and Drug Administration. Present study was aimed to determine the modulatory effect of floral extracts of C. officinalis administrations on mean blood glucose (MBG), per cent glycosylated hemoglobin (HbA1c), lipid profile [(total cholesterol (TC), triglycerides (TG), low and high density lipo...
OBJECTIVE To investigate electrocardiogram changes due to scorpion stings and association between oxidative stress index, body oxidant/antioxidant system and the electrocardiogram changes. METHODS The study was conducted at the Faculty of Medicine, Gaziantep University, Turkey, between May 2009 and October 2010. It comprised 44 patients admitted to the emergency department for scorpion sting,...
Creatine (Cr) is naturally produced in the body and stored in muscles where it is involved in energy generation. It is widely used, especially by athletes, as a staple supplement for improving physical performance. Recent reports have shown that Cr displays antioxidant activity which could explain its beneficial cellular effects. We have evaluated the ability of Cr to protect human erythrocytes...
Selenium participates in the antioxidant defense mainly through a class of selenoproteins, including thioredoxin reductase. Epigallocatechin-3-gallate (EGCG) is the most abundant and biologically active catechin in green tea. Depending upon the dose and biological systems, EGCG may function either as an antioxidant or as an inducer of antioxidant defense via its pro-oxidant action or other unid...
the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...
24 BACKGROUND. There are few studies dealing with the relationship between 25 oxidative stress and ochratoxin A (OTA). In this work we have analyzed the effect 26 of the oxidant stressor menadione and the antioxidpmants 3,5-di-tert-butyl-427 hydroxytoluene (BHT), catechin, resveratrol and a polyphenolic extract on growth, 28 generation of reactive oxygen species (ROS), OTA production and gene 2...
Oxidative stress has been implicated as a causal factor in the aging process of the heart and other tissues. To determine the extent of age-related myocardial oxidative stress, oxidant production, antioxidant status, and oxidative DNA damage were measured in hearts of young (2 months) and old (28 months) male Fischer 344 rats. Cardiac myocytes isolated from old rats showed a nearly threefold in...
the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
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...
