Omega-3 polyunsatuarted fatty acids (PUFA) are associated with hypolipidemic and anti-inflammatory effects. However, omega-3 PUFA, usually administered as triacylglycerols or ethyl esters, could also compromise glucose metabolism, especially in obese type 2 diabetics. Phospholipids represent an
The comparative effects of high-fat diets (20%, w/w) on eicosanoid synthesis during mammary tumor promotion in 7,12-dimethylbenz(a)anthracene (DMBA)-induced rats were studied using diets containing 20% primrose oil (PO), 20% menhaden oil (MO) or 20% corn oil (CO). Sprague-Dawley rats fed the PO or
In order to measure the changes in antioxidant levels and the composition of plasma-free fatty acids resulting from oxidative stress, male Fisher rats were given a twice weekly subcutaneous injection of a 50% solution of carbon tetrachloride (CCl4) in corn oil for a period of 2 to 13 weeks. The
The effects of dietary olive oil, corn oil and medium-chain triglycerides (MCT) on factors that characterized erythrocyte membrane lipid fluidity were studied. Weanling rats were fed for 3 or 5 wk high fat diets (10%) containing olive oil, corn oil or a mixture of MCT with olive oil or corn oil.
Epidemiological and laboratory animal model studies have provided evidence that the effect of dietary fat on colon tumorigenesis depends on the amount of fat and its composition. Because of the importance of the composition of dietary fat and of tissue membrane fatty acid composition in tumor
Previously, we described a priming effect of α-linolenic acid (LnA) on anti-herbivore defense response in maize seedlings. 1 We showed that exogenous application of LnA stimulated higher jasmonic acid (JA) accumulation and herbivore-induced plant volatile (HIPV) emission after treatment with insect
The in vivo fatty acid synthesis rate, selected enzyme activities and fatty acid composition of rat white adipose tissue from animals fed semisynthetic diets of differing fat type and content were studied. All animals were starved for 48 hr and then refed a fat-free (FF) diet for 48 hr. They were
To examine the effect of dietary fat on lung lipids, male weanling mice (CD-1 strain) were fed purified diets containing 5% stripped lard or corn oil and kept in chambers supplied with air filtered free of airborne bacteria. Vitamin E was fed at 0, 10.5 or 105 mg dl-alpha-tocopheryl acetate/kg diet.
A method of on-line pyrolytic methylation-gas chromatography was developed for the analysis of fatty acid composition in cottonseed. Fatty acids in cottonseeds were converted to their corresponding fatty acid methyl esters in the presence of trimethylsulfonium hydroxide at 300℃. The major fatty
To improve hybrid tilapia (Oreochromis niloticusxO. aureus) survival under cold shock, the influence of diets containing various dietary lipids was investigated. Four different diets were used which consisted of 12% fish oil, 12% palmitoleic oil 12% coconut oil, and a mixture of fish oil (7%) and
Twenty-one crossbred gilts and 75 crossbred sows were randomly assigned to six treatments for examination of the effect of lipid feeding and choline level on baby pig survival. Dietary variables were supplemental fat and choline in a 3 X 2 factorial arrangement. Fat treatments were no supplemental
Phospholipase A2 (PLA2) functions as the rate-limiting step in arachidonic acid metabolism and in the removal of damaged or peroxidized membrane lipids. It is elevated in some human tumors and may be involved with mechanisms of tumor promotion. In vitro systems have shown PLA2 activity to be altered
The purpose of this work was to analyze the effect of diets that contain several oils whose composition in fatty acids were different, on the kinetic parameters of the gamma-glutamyltranspeptidase (GGTP) and the lipoperoxidation of the epididymis because GGTP controls the level of the glutathione
Linoleic acid (18:2 omega 6) and linolenic acid (18:3 omega 3) are precursors of two series of essential fatty acids (EFA) formed by alternate desaturations and elongations. In EFA deficiency (EFAD), oleic acid (18:1 omega 9) and palmitoleic acid (16:1 omega 7) undergo the same reactions to form
Dietary oils such as corn oil, olive oil, and canola oil, which primarily contain triacylglycerol and small quantities of fatty acids, are highly palatable to animals. In a previous study, we examined the short-term (60 s) licking behavior of mice and observed that they exhibited a high licking
