Starting at 21 days of age, groups of six rats each were fed a basal Torula yeast diet supplemented with 0.4% L-methionine and varying amounts of vitamin E as dl-alpha tocopherol acetate, selenium as sodium selenite, and with either 10% stripped corn oil, stripped lard, or coconut oil. By 7 wk,
Pentane is one decomposition product of omega 6-unsaturated lipid hydroperoxides. The measurement of respiratory pentane is one of the most sensitive in vivo tests of lipid peroxidation. This measurement was applied to test the ability of a low level, short-term exposure of rats of nitrogen dioxide
One useful method to monitor in vivo lipid peroxidation is the measurement of volatile hydrocarbons, mainly pentane and ethane, that derive from unsaturated fatty acid hydroperoxides. Vitamin E, the biological antioxidant, inhibits lipid peroxidation and the production of pentane and ethane. The
Measurements were made of pentane, a produce of lipid peroxidation, and chloroform (CHCl3), a product of the reproductive metabolism of carbon tetrachloride (CCl4), expired by rats administered CCl4 plus either phenobarbital (PB), 2-diethylaminoethyl-2,2-diphenyl valerate hydrochloride (SKF-525A),
The role of chemical stimuli in host selection and oviposition of Sesamia nonagrioides (Lef) was studied in the laboratory using eight corn hybrids. Female oviposition preference was evaluated on plants of the eight hybrids, their extracts in pentane and methanol, and volatiles collected by steam
The influence of dietary vitamin E and Santoquin on lipid peroxidation and liver regeneration in partially-hepatectomized rats was studied. Rats were fed either a basal 10% tocopherol-stripped corn oil diet, the basal diet plus 40 mg dl-alpha-tocopheryl acetate/kg, or the basal diet plus 2 g
The effect of in vivo lipid peroxidation on the excretion of immunoreactive prostaglandin E2 (PGE2) in the urine of rats was studied. Weanling, male Sprague-Dawley rats were fed a vitamin E-deficient diet containing 10% tocopherol-stripped corn oil (CO) or 5% cod liver oil (CLO) with or without 40
Volatile formation is an inevitable result of lipid oxidation, which impact the quality of lipid rich foods. In this study, moisture role on the formation of volatiles were evaluated using deuterium oxide (D2O) and possible steps of moisture involvement were suggested. Moisture content in corn oil
The increased expiration of ethane and pentane by mice treated with hepatotoxic doses of acetaminophen suggests the possibility of oxidant mechanisms associated with the necrosis. However, studies in rats are not consistent with oxidant stress mechanisms causing the damage, because acetaminophen
Biosurfactant production using Candida bombicola ATCC 22214, its characterization and potential applications in enhancing oil recovery were studied at laboratory scale. The seed media and the production media were standardized for optimal growth and biosurfactant production. The production media
