Effects of culture pH and corn oil (CO) concentration on biohydrogenation (BH) of unsaturated fatty acids and disappearance of neutral detergent fiber (NDF) in batch culture were evaluated in a 2 × 3 factorial design experiment. Culture vessels (100 mL; 4 replicates/treatment per time point)
The viability pattern of the unsaturated fatty acid sensitive mutant (cos/cos) of Tribolium castaneum was examined with reference to the normal genotype from egg hatching through adult emergence. The beetles were cultured on diets with 0, 3, or 5% corn oil in growth chambers maintained at 33 +/- 1
Three experiments evaluated the lipids in distillers grains plus solubles compared with corn or other sources of lipid in finishing diets. Experiment 1 utilized 60 individually fed yearling heifers (349 +/- 34 kg of BW) fed treatments consisting of 0, 20, or 40% (DM basis) wet distillers grains plus
The relative concentration of long-chain unsaturated fatty acids (chain length C(20) and greater) of the (n - 6), (n - 7), and (n - 9) families in the cholesteryl esters and phospholipids of rat adrenals, liver, heart, and plasma lipoproteins was measured after the feeding of hydrogenated fat, milk
OBJECTIVE
The objective of this study was to determine the effects of saturated fatty acid (SFA) and unsaturated fatty acid (UFA) diets on ethanol pharmacokinetics. Hepatic ADH and plasma carnitines were also evaluated as possible indicators of the mechanism involved.
METHODS
Sprague-Dawley male
The study investigated the changes in individual molecular species in PE and the effects of a variety of dietary fats with varying proportions of saturated and unsaturated fatty acids on membrane composition, eicosanoid production and cytokine production in thioglycollate-elicited rat macrophages.
The quantity of leukotrienes produced in an inflammation model, the stimulated mouse peritoneum, was affected by dietary manipulation of tissue arachidonic acid, the immediate leukotriene (LT) precursor. Fifty ng of LTE4 was synthesized (after injection of zymosan) by the peritoneal cavity of mice
OBJECTIVE
This study was launched to determine comparative effects of corn oil (CO), safflower oil (SO), fish oil (FO) and palm oil (PO) on carnitine status and ethanol metabolism in rats.
METHODS
Twenty-four male Sprague-Dawley rats (300 g bw) were randomly divided into four groups (n = 6) and fed
Corn oil has been recommended as a replacement for saturated fats because of its high levels of poly- and mono-unsaturated fatty acids. In the present study, we tested whether very high levels of corn oil (58.6% fat-derived calories, FDC) intake improve health and longevity of aging mice. Twelve
BACKGROUND
Although supplementing the diet with large quantities of phytosterols reduces cholesterol absorption and LDL-cholesterol concentrations, very little is known about the smaller amounts of phytosterols present naturally in food. Vegetable oils are the richest dietary source of phytosterols;
There is a trend to use more alternative lipids in poultry diets, either through animal-vegetable blends, distillers corn oil, or yellow grease. This has resulted in the use of lipids in poultry diets with a higher concentration of unsaturated fatty acids, which have a greater potential for
We previously made a RNAi-based cytochrome P450 2b (Cyp2b)-knockdown (Cyp2b-KD) mouse to determine the in vivo role of the Cyp2b subfamily in xenobiotic detoxification. Further studies reported here indicate a role for Cyp2b in unsaturated fatty-acid (UFA) metabolism and in turn obesity. Mice were
Autooxidation of polyunsaturated fatty acids (PUFAs) of edible oils results in the formation of fatty acid hydroperoxides that can undergo further chemical transformations to yield a variety of re-arranged and chain-cleavage products. Since the oxidation products of PUFAs have been reported to have
The addition of a fish oil supplement rich in n - 3 unsaturated fatty acids to a high cholesterol, high saturated fat (BT) diet for swine has been shown previously to result in modest lowering of plasma cholesterol levels and in marked retardation of atherogenesis. It has been suggested that the
The objective of this study was to examine the effect of a dietary synthetic antioxidant on feed intake, yields of milk and milk components and milk fatty acids (FA), in combination with increasing concentrations of dietary corn oil to provide increasing rumen unsaturated fatty acid load (RUFAL)
