abstract background and objective: diabetes mellitus is associated with cardiomyopathic changes, can be mediated by an oxidative stress. we aimed to study the effects of regular aerobic training and arbutin supplementation on total oxidant status (tos) and total antioxidant (tas) status in the cardiac tissue of diabetic rats. material and methods: fourty-two male wistar rats with an average wei...

the aim of this study was to investigate the effective concentration of ethanolic extract  of bee pollen on liver, spleen and heart tissues of fish. bee pollen extract in various concentrations (0.5, 2.5, 5, 10, 20 and 30 ppm) was administered to fish for 96 h under aquarium conditions. the malondialdehyde (mda) levels, total antioxidant status (tas), total oxidant status (tos), oxidative stres...

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...

several lichen species have been used for medicinal purposes throughout the ages, and they were reported to be effective in the treatment of different disorders including tuberculosis, hemorrhoids, ulcer, dysentery and cancer. it is revealed that they may be easily accessible sources of natural drugs that could be used as a possible food supplement or in pharmaceutical industry after their safe...

Potentially damaging species (reactive oxygen, nitrogen and chlorine species) arise as by-products of metabolism and as physiological mediators and signalling molecules. Levels of these species are controlled by the antioxidant defence system. Several components of this system are micronutrients (e.g. vitamins C and E) or are dependent upon dietary micronutrients (e.g. CuZn and Mn superoxide di...

BACKGROUND Severe mammary tissue damage during acute coliform mastitis in cattle is partially caused by oxidative stress. Although considered a gold standard biomarker in some human conditions, the utility of 15-F2t-Isoprostanes (15-F2t-Isop) in detecting oxidative stress in dairy cattle has not been validated. HYPOTHESIS Concentrations of 15-F2t-Isop in plasma, urine, and milk correlate with...
