to evaluate the concentrations of serum lipids and lipoproteins and their correlations together and withthyroid hormones in gray necked ostrich (struthio camelus), the serum levels of cholesterol, triglyceride,total lipids, very low density lipoproteins (vldl-cholesterol), low density lipoproteins (ldl-cholesterol)and high density lipoproteins (hdl-cholesterol) and their correlations with tri-i...

Lipid composition of serum lipoproteins was studied in Holstein cows throughout gestation and lactation. Blood serum lipids varied with stage of gestation or lactation; however, the percent lipid distributed in the cholesteryl esters, phospholipids, and unestcrtfied cholesterol did not vary. Cholesteryl esters and phospholipids accounted for approximately 90~ of the lipid content of whole serum...

introduction: hyperlipidemia is a risk factor for atherosclerosis and cardiovascular diseases. nuts such as almonds are high in unsaturated lipids and antioxidants. some studies indicate that nuts have beneficial effects on cardiovascular system. therefore, the aim of this study was evaluation of the effectiveness of shelled almonds on reduction of blood lipid and lipoprotein levels in hyperlip...

The uptake, distribution, and exchange of chlorinated hydrocarbon insecticides (dieldrin and chlordecone) and biphenyls (2,4,5-2',4',5'-hexachlorobiphenyl and 3-chlorobiphenyl) among human lipoproteins was examined by fluorescence quenching, gel filtration, and ultrafiltration. The chlorinated hydrocarbons were rapidly taken up from solution or silica particles by lipoproteins. The distribution...

We have isolated and partially characterized five populations of lipoproteins from the pool of immunoisolated apoA-I-containing lipoproteins obtained from normal human plasma. The first three populations, each containing apoA-I and apoE, were isolated completely by sequential, selected affinity immunosorption against apoA-I and apoE. The lipoproteins isolated by this strategy fall into three mo...

In previous studies, we have shown that a relatively large amount of low density lipoproteins is released into the perfusate during isolated pig liver perfusion. The present studies were done to determine the source of these lipoproteins. Breakdown of the very low density lipoproteins to low density lipoproteins by the perfusion apparatus or by hepatic catabolism was excluded by adding 125I ver...

The direct vasoactive effects of native and oxidatively modified low density lipoproteins as well as their effects on endothelium-dependent relaxations to 5-hydroxytryptamine were studied in isolated rings of pig right coronary artery. Slowly developing contractions were caused by native low density lipoproteins (100 gg protein/ml). The contractions were more pronounced in the absence than in t...

The intestine has long been recognized as n organ active in lipoprotein formation. This is hardly surprising when one considers the large quantities of dietary and endogenous lipids that traverse the intestinal mucosa daily and are absorbed into the mesenteric lymph as lipoproteins. Until recently, the major focus of research on intestinal ipoprotein metabolism was concerned with the intesti...

Abstract Histochemical staining of histological sections Varroa destructor (Anderson and Trueman, 2000) mites reveal the internal body plan are used to contrast organs associated with feeding reproduction starved versus recently fed female mites. The gnathosoma is comprised a powerful sucking pharynx, which employs 11 alternating dilator constrictor muscles, chelicerae, salivary ducts, salivari...

Understanding the chemical nature of biomarkers and their interaction with host environment is critical to both development implementation diagnostic tools therapeutics. Human lipoproteins, such as high-density lipoprotein (HDL) low-density (LDL), are important carrier molecules for transporting cholesterol other lipid organs where they can be processed. These lipoproteins have more recently be...
