Consumption of n-3 polyunsaturated fatty acids (n-3 PUFAs) is associated with a reduced incidence of coronary arterial diseases. Dietary n-3 PUFAs act via several mechanisms. They depress plasma lipids, especially triglycerides (TGs), by inhibiting hepatic TGs and possibly apoprotein synthesis. They replace arachidonic acid (AA) in phospholipid pools with(More)
The "French paradox" (apparent compatibility of a high fat diet with a low incidence of coronary atherosclerosis) has been attributed to the regular drinking of red wine. However, the alcohol content of wine may not be the sole explanation for this protection. Red wine also contains phenolic compounds, and the antioxidant properties of these may have an(More)

Dietary polyunsaturated fatty acids can significantly affect many biochemical and physiologic functions that are related to inflammatory, immune, and protective reactions. The different types of fatty acids can impact on energy metabolism, determine the lipid composition of membranes, and influence eicosanoid synthesis, all of which are relevant to(More)
Tumor necrosis factor (TNF) is a macrophage derived peptide that has an antitumor action and modulates immune and inflammatory reactions. Dietary fatty acids may modulate TNF production as dietary n-3 polyunsaturated fatty acids suppress human monocyte TNF production, but enhance its secretion by murine peritoneal macrophages. Mice were maintained for 5(More)
The comparative effects of dietary alpha-linolenic acid and fish oil on eicosanoid metabolism was studied in vivo. Resident murine peritoneal cells were stimulated in vivo with opsonized zymosan in animals maintained on diets containing increasing amounts of alpha-linolenic acid or fish oil concentrate with projected n-3/n-6 ratios of 0.2, 0.4 and 1.0.(More)
Modification of cultured lymphoma cells (L5178Y) with individual unsaturated fatty acids [oleic acid (OA), linoleic acid (LA), alpha-linolenic acid (alpha-LNA), arachidonic acid (AA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA)] influenced cell growth and the responses of the cells to the chemotherapeutic agents doxorubicin (DRN),(More)
The ripening of blue and Roquefort cheeses is accomplished by the concerted and controlled actions of enzymes of the mold Penicillium roqueforti. The properties and effects of the enzymes involved in flavor development (i.e., proteases, lipase and beta-ketoacid decarboxylase) are reviewed. The metabolic activities of both spores and mycelia of P. roqueforti(More)
The effects of 5, 10 and 20% dietary menhaden oil (MO) on the composition of heart lipid classes and fatty acids were studied. Male Sprague-Dawley rats were fed ad libitum 0, 5, 10 and 20% MO for 3 wk. The heart phosphoglyceride content and composition and cholesterol were unchanged by dietary MO. A nonlinear dose-response relationship was observed between(More)
The uricase (urate: oxygen oxidoreducase EC.1.7.3.3) activities in livers from rainbow trout, mackerel, lake trout, catfish, shark and tilapia were 1000, 1180, 920, 630, 490 and 420 units (n moles uric acid oxidized mg-1 protein min-1) per gram liver, respectively. The enzyme from lake trout was purified twenty fold by ammonium sulfate precipitation,(More)
