To evaluate meat quality of beef with different α-tocopherol tissue levels, 55 feedlot steers were fed a barley-based finisher diet with four vitamin E supplementation levels (0, 350, 700 and 1400 IU DL-α-tocopheryl acetate/animal per day) for 120 days. Although the increase in oxidation levels overtime was much smaller (P < 0.001) in the high-medium and high groups, α-tocopherol tissue levels ...

BACKGROUND Research indicates that oxidative stress induced by smoking plays a role in breast cancer. In view of these reports, we aimed to study th relationship between smoking and oxidative stress in breast cancer patients from the western region of Nepal. MATERIALS AND METHODS The study included a control group of 42 females (non-smoking healthy women) and a test group sudivided into Group...

It is aimed to achieve the optimized for vitamin E (dl-α-tocopherol acetate) micro-encapsulation through complex coacervation at high efficiency with this study. The response surface methodology (RSM) was used optimize microencapsulation state of E. microencapsulated tocopherol investigated in terms two variables including amount core material (vitamin E) and concentration surfactant (SDS). Acc...

Abstract Background Direct measurement of the bioavailable α-tocopherol content presents a significant analytical challenge and requires chiral separation stereoisomers. Objective The objective study was to validate an method for analysis stereoisomers in infant formulas dairy products. Method Samples were saponified at elevated temperature lipophilic components extracted into organic solvent, ...

A dose-response meta-analysis was conducted to assess the association of vitamin C, D, E with risk of bladder cancer. Pertinent studies were identified in PubMed and Embase. The random-effect model was used. The relative risk (95% confidence interval) of bladder cancer was 0.99 (0.95-1.03) for every 100 IU/day increment in vitamin D from diet plus supplement and 0.95 (0.90-1.00) for every 10 nm...

Reference interval of all haematological and biological analytes should be measured for every population because of the huge diversity in genetic make-up, dietary habits. The coverage interval of antioxidant vitamins (vitamin C and α -tocopherol) in the plasma and serum of reference Bengali population was determined and compared with the reference intervals of antioxidant vitamins in the establ...

BACKGROUND The role of non-enzymatic antioxidants, such as uric acid, albumin, bilirubin, and α-tocopherol, in lead poisoning remains unclear. Therefore, the aim of the study was to explore the association between occupational exposure to lead and non-enzymatic antioxidant concentrations in serum and plasma. MATERIAL AND METHODS The study population consisted of 278 healthy male employees of ...

one of the simplest methods for short-term handling and storage of fish is the refrigeration in combination with dip treatments. this study was conducted to determine the effect of pre-storage α-tocopherol acetate dipping treatments on lipid stability of refrigerated rainbow trout fillets. trout fillets were dipped in α-tocopherol acetate solutions (200 and 500 mg kg-1 flesh) and subsequently s...
