The objective of the present study was to determine the effect of Se inclusion in high-DHA and vitamin E microdiets (5 g DHA/100 g dry weight and 300 mg vitamin E/100 g dry weight; 5 g DHA/100 g dry weight and 300 mg vitamin E/100 g dry weight supplemented with Se) in comparison with a control diet (1 g DHA/100 g dry weight and 150 mg vitamin E/100 g dry weight) on sea bass larval growth, survi...

Fast-growing broiler chicks are susceptible to Se deficiency diseases including exudative diathesis (ED). Our objective was to determine if ED could be induced by feeding a current, practical diet and if the incidence was related to selenogenome expression in liver and muscle of chicks. Four groups of day-old broiler chicks (n = 60/group) were fed a corn-soy basal diet (BD; 14 μg Se/kg; produce...

Feeding diets depleted of vitamin E and Se to cattle can induce a disease known as nutritional degenerative myopathy. It is believed that an increased peroxidative challenge in muscle is involved in the pathogenesis of this disease. A number of species can up-regulate the activity of some antioxidant enzymes, including glutathione reductase (EC 1.6.4.2), glutathione transferase (EC 2.5.1.18), g...

Three antioxidant food supplements were analysed for selenium (Se) and its species. Sample A main constituents were coenzyme Q10, selenium (as medical yeast), vitamin C and natural vitamin E. The product is used for maintaining health and strengthening physical and mental abilities, stimulating the immune system, inhibiting the development of atherosclerosis, strengthening a weakened heart. Sam...

1. The natural abundance carbon-13 nmr of vitamins D (D2 and D3) and several isomers (5, 6-trans-vitamin D2, isotachysterol2 and isovitamin D2) have been completely assigned by employing off-resonance noise-decoupling, acetylation shifts, and lanthanide-induced shifts experiments. The last two techniques were especially useful for the present study. 2. Carbon-13 nmr spectral characteristics of...

A number of antioxidants and trace minerals have important roles in immune function and may affect health in transition dairy cows. Vitamin E and beta-carotene are important cellular antioxidants. Selenium (Se) is involved in the antioxidant system via its role in the enzyme glutathione peroxidase. Inadequate dietary vitamin E or Se decreases neutrophil function during the perpariturient period...

vitamin e (alpha-tocopherol) is a potent and natural antioxidant. vitamin e is concentrated from soybean oil. the committee on fetus and newborn of the academy of the american of pediatrics endorsed 1 to 2 mg/dl as the normal range of serum tocopherol level. human infants are born with low stores of vitamin e, thus they require an adequate intake of vitamin e soon after birth. the optimum intra...

Present study was designed to assess the effect of vitamin E+Se supplementation on growth performance as well as antioxidant status in arsenic toxicity in experimental goats. Eighteen cross breed goats of either sex, aged between 12 to 24 months of age were randomly selected and divided into three groups. Group I was considered as healthy control. Goats of group II and III received Sodium arsen...

The mode of action of vitamin E is still not fully understood. One hypothesis, however, is that it is a physiological antioxidant, preventing the accumulation of undesirable metabolic oxidation products in animal tissues. These products are usually supposed to be lipid peroxides, which, in the absence of vitamin E or other antioxidant, can break down to give free radicals that can react at rand...

objective vitamin e is a major lipid-soluble antioxidant. it has been demonstrated that vitamin e supplementation has a beneficial effect against coronary heart disease (chd). this study to investigate the effects of coronary risk factors on serum vitamin e status in patients with dyslipidaemia. materials and methods this tertiary care hospital; case - control study was comprised 237 dyslipidae...
