We demonstrate here that CD59, an inhibitor of the membrane attack complex (MAC) of the complement system, is present in cell-free seminal plasma (SP) at a concentration of at least 20 micrograms/ml. Analyses by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, Western blotting, and Edman degradation indicated that this protein, SP CD59, was(More)
The purpose of this study was to evaluate the effect of medium-chain triglycerides (MCT) with and without exercise on postprandial lipemia (PPL). Subjects were 25 young men and women. Each subject performed three trials: 1) control (fat meal only, 1.5 g fat/kg) 2) MCT (substitution of MCT oil, 30% of fat calories), and 3) MCT + Ex (exercise 12 h before the(More)
Dietary cholesterol and dietary saturated fatty acids affected the plasma concentrations of various HDL components and the hepatic and intestinal expression of the apolipoprotein (apo) A-I gene and the hepatic expression of the A-II gene differently in three inbred strains of female mice. Thus, the HC diet (0.5% cholesterol, no added fatty acids) decreased(More)
BACKGROUND The benefits of omega-3 (n-3) long-chain polyunsaturated fatty acids to heart health are well established. Stearidonic acid (SDA, 18:4n-3) may contribute to these benefits. OBJECTIVE The objective was to evaluate the ability of SDA-containing soybean oil to increase the omega-3 index [erythrocyte eicosapentaenoic acid (EPA) + docosahexaenoic(More)
The conformations of apolipoproteins on the surfaces of lipoprotein particles affect their physiologic functions. The conformations of apoE on plasma lipoproteins were examined using a panel of eight anti-apoE monoclonal antibodies (MAbs). The antibodies, which reacted with the major isoforms of apoE (E2, E3, and E4), defined at least five epitopes on apoE.(More)
To elucidate further the conformation of human apolipoprotein A-I (apoA-I) in lipid-bound states and its effect on the reaction with lecithin cholesterol acyltransferase (LCAT), we prepared reconstituted HDL (rHDL) particles from a reaction mixture containing dipalmitoylphosphatidylcholine/cholesterol/apoA-I in the molar ratios of 150:7.5:1. The particles(More)
Estrogen protects against developing premature coronary artery disease.However, the mechanism of protective effects of estrogen still remainspoorly understood. One mechanism by which estrogen can have protectiveeffects apppears to be through modulation of plasma lipoproteins. We showedthat the mouse can be used as animal model to study(More)
OBJECTIVE The purpose of this randomized, controlled, parallel group study was to characterize the relationships between dosages of stearidonic acid (SDA) and eicosapentaenoic acid (EPA), and incorporation of EPA into red blood cell (RBC) membranes over time. METHODS Healthy subjects (n=131) received capsules with placebo (safflower oil), SDA (0.43, 1.3,(More)
The usefulness of monoclonal antibodies as probes of protein structure is directly related to knowledge of the structures and locations of the epitopes with which they interact. In this report we provide a detailed map of 13 epitopes on apoB-100 defined by our anti-apoB monoclonal antibodies based on current information on the amino acid sequence of(More)
BACKGROUND Consumption of soybean oil enriched with stearidonic acid was previously shown to increase eicosapentaenoic acid (EPA) in red blood cells (RBC). OBJECTIVE This study was designed to evaluate the effect of stearidonic acid oil used as a food ingredient in baked products and beverages on the RBC fatty acid profile. DESIGN This was a randomized,(More)
