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...

background: spermatozoa preservation is an approach to improve the fertility rate to pass on the valuable genetic material from sire to their offspring. during the last 20 years, reproductive biotechnologists have focused on the approaches that improve spermatozoa cryosurvival. one of the possible mechanisms is supplementation in semen extender. objectives: the aim of this study was to evaluate...

noise induced hearing loss (nihl) is one of the most important occupational disease worldwide. nihl has been found potentiate by simultaneous carbon monoxide (co) exposure. free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the co hypoxia. this study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

Twenty-four crossbred beef cows were used to investigate the concentration of alpha-tocopherol in plasma and tissues following oral administration of four tocopherol sources. Animals were allotted to the following treatments: DL-alpha-tocopherol, D-alpha-tocopherol, DL-tocopheryl acetate and D-alpha-tocopheryl acetate. Animals received a daily oral dose of 1,000 IU of the respective tocopherol ...

BACKGROUND/OBJECTIVES Vitamin E is a fat-soluble vitamin and functions primarily as a lipid antioxidant. Inadequate vitamin E status may increase risk of several chronic diseases. Thus, the objectives of this study were to estimate intake and plasma concentration of each tocopherol and to evaluate vitamin E status of Korean adults. SUBJECTS/METHODS Three consecutive 24-h food recalls and fast...

BACKGROUND Little is known about α-tocopherol's bioavailability as a constituent of food or its dependence on a subject's age. OBJECTIVE To evaluate the α-tocopherol bioavailability from food, we used collard greens grown in deuterated water ((2)H collard greens) as a source of deuterium-labeled ((2)H) α-tocopherol consumed by younger and older adults in a post hoc analysis of a vitamin K stu...

OBJECTIVE To evaluate alpha-tocopherol concentrations in maternal serum and colostrum under fasting and postprandial conditions. METHODS Thirty healthy childbearing women were recruited in a public maternity hospital, and samples of blood, fasting colostrum, and postprandial colostrum were collected from them up to 12 hours after delivery. RESULTS The serum alpha-tocopherol concentration wa...
