BACKGROUND Nonalcoholic steatohepatitis (NASH) is a progressive form of nonalcoholic fatty liver disease and a risk factor for cirrhosis, hepatocellular carcinoma and liver failure. Previously, we reported that dietary docosahexaenoic acid (DHA, 22:6,n-3) was more effective than eicosapentaenoic acid (EPA, 20:5,n-3) at reversing western diet (WD) induced NASH in LDLR(-/-) mice. METHODS Using ...

Macrophage cholesterol accumulation and foam cell formation, the hallmark of early atherosclerosis, is the result of enhanced cellular uptake of plasma low density lipoprotein (LDL). Native LDL, has to undergo oxidative modifications in order to be taken up at an enhanced rate by macrophages, leading to foam cell formation. Macrophage uptake of oxidized LDL involves its binding to scavanger rec...

Clinicians commonly measure the (13)CO(2) in exhaled breath samples following administration of a metabolic tracer (breath testing) to diagnose certain infections and metabolic disorders. We believe that breath testing can become a powerful tool to investigate novel questions about the influence of ecological and physiological factors on the oxidative fates of exogenous nutrients. Here we exami...

Pequi is the fruit of Caryocar brasiliense and its oil has a high concentration of monounsaturated and saturated fatty acids, which are anti- and pro-atherogenic agents, respectively, and of carotenoids, which give it antioxidant properties. Our objective was to study the effect of the intake of a cholesterol-rich diet supplemented with pequi oil, compared to the same diet containing soybean oi...

A culture enriched by growth on 1-methylnaphthalene was used to study the aerobic biotransformations of benzothiophene and 3-methylbenzothiophene. Neither of the sulfur heterocyclic compounds would support growth, but they were transformed by the culture growing on 1-methylnaphthalene or glucose or peptone. Cometabolism of benzothiophene yielded benzothiophene-2,3-dione, whereas that of 3-methy...

The objective of this work was carried out to study the evaluate air frying process as a new technique for frying process. The Potato strips were fried in both air-frying machines (Tefal Actifry) at 180oC±5oC for 40 min and traditional frying process at 180oC for 40 min, 6 min/batch. After frying, the moisture and oil uptake were determined. Changes in some physico-chemical properties of oil ex...

Nitrate in water from tile drained corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] fields in the U.S. Midwest contributes to nitrate contamination of surface waters. Denitrification-based biofilters are a promising strategy for reducing nitrate concentrations, but these systems require an external carbon supply to sustain denitrification. The ability of four organic materials to serve a...
