HE MECHANISM WHEREBY water-insoluble fat can pass through the intestinal epithelium and into the blood has been a very intriguing as well as a most refractory problem. Obviously, the fat must either pass as particles or it must be solubilized, and various theories have been devised based on both possibilities. Most studies on the degree of hydrolysis of fat during digestion have been undertaken...

• After a fatty meal, plasma lipemia, as measured by increase in optical density in a colorimeter, is significantly greater throughout the period of absorption in patients with ischemic heart disease than in control subjects.' " The extent of the lipemia depends on contemporary processes of absorption and fat clearance. The rate of absorption depends on such factors as gastric emptying and the ...

purpose: military personnel are expected to maintain the highest possible level of physical   fitness to do their duties. several factors including body composition and body mass index   affect the level of their physical preparedness. the current study was designed to investigate   the effect of body composition and body mass index in the level of physical preparedness of   iranian military pe...

Percent cholesterol absorption was measured in 94 normal subjects aged 17- 80 years while consuming diets generally low in cholesterol (mean intake = 226 +/- 126 mg/day). A new dual stable isotope method was used where a cholesterol tracer containing 6 extra mass units was given intravenously and another tracer with 5 extra mass units was given orally during a standard test meal. The ratio of t...

Apolipoprotein A-IV (apoA-IV) is synthesized by intestinal enterocytes during lipid absorption and secreted into lymph on the surface of nascent chylomicrons. A compelling body of evidence supports a central role of apoA-IV in facilitating intestinal lipid absorption and in regulating satiety, yet a longstanding conundrum is that no abnormalities in fat absorption, feeding behavior, or weight g...

This pollution accumulation model shows that the environmental absorption capacity is impacted by economic activity. The resulting optimal control problem has two inter-related state variables: the stock of pollution and the absorption capacity of the environment. The stock of pollution decreases with environmental absorption capacity and increases with the rate of current emissions, which is c...

Barley, oats and wheat flour was used to formulate composite (CF). Composite (CF) made by substituting with barley in different proportions of blending, that is20%, 40%, 60% 80%. The physical functional attributes blends were studied. qualitative analysis the prepared multigrain cookies examined on basis proximate analysis. In flour, content fat, protein carbohydrate increased as mixing proport...

Fat digestion in the breastfed newborn infant is a process catalyzed by three Upases. The process is initiated in stomach contents by gastric lipase and continues in the upper part of the small intestine by pancreatic colipase-dependent lipase and human milk bile-salt-stimulated lipase (BSSL). Development of powerful techniques in molecular biology has made it possible to gain better insight in...

Cholesterol absorption, fecal elimination, and synthesis and low density lipoprotein (LDL) metabolism were measured in 29 middle-aged men while on their normal diet and a diet low in fat and cholesterol, and the obtained values were related to apoprotein (apo) E phenotypes. Basal cholesterol absorption efficiency was positively related to production rate (PR) for LDL apo B and negatively to cho...
