INTRODUCTION: Strenuous exercise in sedentary individuals increases the acute risk of atherothrombotic events and depletes endogenous antioxidants. Supplementation with the antioxidant tocopherol ameliorates the risk; however it is unclear whether α-tocopherol, γ-tocopherol or a combination of both is more efficacious. We therefore measured the effects of γ-,αand mixed tocopherol supplementatio...

Male young growing rats of Wistar strain (n=54) were fed a vitamin E deficient diet for 3 days of adaptation period and then 10 days of experimental period. After adaptation half of the rats ran, once per a day, on a treadmill with a rate of 2.0 m/s for 15 minutes for the following 10 days. Animals were given orally 0, 0.5, 1.0 or 4.0 mg/d/rat of α-tocopherol. The aim of the study was to evalua...

Designing enriched probiotic supplements may have some advantages including protection of probiotic microorganism from oxidative destruction, improving enzyme activity of the gastrointestinal tract and probably increasing half-life of micronutrient. In this study Saccharomyces cerevisiae enriched with α-tocopherol produced as an accumulator and transporter of a lipid soluble vitamin for the fir...

The impacts of α-tocopherol, glycine betaine (GB) and salicylic acid (SA) applications on higher plants have been the subject of many studies, with special emphasis on oxidative stress tolerance under adverse conditions. However, little work has been carried out on rice responses to α-tocopherol, GB or SA under non-stress conditions, in which yield could potentially increased. This study determ...

Aristolochic acid (AA) is a component identified in traditional Chinese remedies for the treatment of arthritic pain, coughs and gastrointestinal symptoms. However, previous studies have indicated that AA can induce oxidative stress in renal cells leading to nephropathy. α‑tocopherol exists in numerous types of food, such as nuts, and belongs to the vitamin E isoform family. It possesses antiox...

Neurodegeneration is the progressive loss of structure or function neurons. Amyloid beta oligomers and aggregates have been linked to neurodegeneration. While previous studies suggested that dietary α-tocopherol intake can prevent amyloid aggregation protect brain against neurotoxicity, other research, however, indicated tocotrienol forms might be used as an alternate agent this kind degenerati...

The aim of this study was to evaluate the preventive effectiveness of dry cow therapy based on antibiotic, internal teat sealant, and α-tocopherol administered separately or in various combinations at drying-off. The study was performed on 322 uninfected quarters of 95 cows originating from three dairy herds. The new intramammary infection rates after calving were measured to evaluate the effec...

The present study was conducted to compare the supplementation of natural (D-α-tocopherol) and synthetic (DL-α-tocopherol acetate) vitamin E on the growth performance, meat quality, muscular antioxidant capacity and genes expression related to oxidative status of broilers. A total of 144 1 day-old Arbor Acres broiler chicks were randomly allocated into 3 groups with 6 replicates of 8 birds each...
