The objectives of the current study were to 1) determine whether a fish-meal-supplemented diet fed to ewes during late gestation and early lactation would increase the proportion of docosahexaenoic acid (22:6n-3) in colostrum and milk and 2) examine the subsequent effect on the plasma fatty acid profile of nursing lambs. Eight gestating ewes (Rideau-Arcott; 97 +/- 5 kg of initial BW; 100 d of g...

There has been much interest in the health effects of dietary fat, but few studies have comprehensively compared the acute metabolic fate of specific fatty acids in vivo. We hypothesized that different classes of fatty acids would be variably partitioned in metabolic pathways and that this would become evident over 24 h. We traced the fate of fatty acids using equal amounts of [U-(13)C]linoleat...

The common housefly, Musca domestica, is a considerable component of nutrient recycling in the environment. Use of housefly larvae to biodegrade manure presents an opportunity to reduce waste disposal while the rapidly assimilated insect biomass can also be used as a protein rich animal feed. In this study, we examine the biodegradation of dairy cattle manure using housefly larvae, and the nutr...

Previous studies in this laboratory have elicited a monophasic response in postprandial plasma triacylglycerol (TAG) level with fat intakes of 0.5 g fat/kg body weight accompanied by about 17 g carbohydrate as lactose. Recent studies involving the same level of fat with a higher level of carbohydrate, 136 g of which 60 g was sucrose, appeared to elicit a biphasic response. The present study com...

introduction: despite presence of a body of evidence in support of high accuracy of cholecystokinin cholescintigraphy (cck-cs) , for diagnosis of chronic cholecystitis(cc) , some authors have claimed that  gallbladder ejection fraction (gbef)  has poor predictive diagnostic values. the purpose of this study was to determine if there is any difference in gbef between normal individuals and patie...

Apparent digestibility coefficients (ADCs) of dry matter, crude protein, crude lipid, energy, essential amino acids, and fatty acids in extruded pellets containing various fish meals were determined for olive flounder (Paralichthys olivaceus). Eight extruded pellet diets were prepared to contain different fish meals (herring fish meal, anchovy fish meal, mackerel fish meal, sardine fish meal-A,...

Because n-3 fatty acid ingestion and aerobic exercise each has been associated with diminished postprandial lipemia (PPL), the purpose of this study was to evaluate the effect of a combination of these two factors on PPL. Sedentary men underwent a standard dietary preparation, including a 12-h fast before each trial. Six subjects performed a control trial (fat meal, 100 g fat) and an n-3 fatty ...

Extraction of oil from poor quality pistachios results in increased add-value. In this study, the performance of different solvents in recovery of valuable oil and meal from the pistachio sample contaminated with aflatoxin was investigated and some chemical properties of the extracted oil were determined. The pistachio nut oil was extracted by three solvent systems including n-hexane (non- pola...

The influence of meals on the coagulability of blood was studied in experiments on 20 men with parallel nonfed controls. The whole blood clotting time in siliconized tubes was not altered by a low-fat meal or by continued absence of a meal, but it was significantly shortened after a meal containing 100 Gm. of butterfat. The degree of lipemia did not determine the degree of shortening. There was...

Individuals with insulin resistance and type 2 diabetes have an impaired ability to switch appropriately between carbohydrate and fatty acid oxidation. However, whether this is a cause or consequence of insulin resistance is unclear, and the mechanism(s) involved in this response is not completely elucidated. Whole-body fat oxidation and transcriptional regulation of genes involved in lipid met...
