Aluminum phosphates (APO-5s) were synthesized and evaluated as heterogeneous catalysts for the valorization of furfural to furfuryl acetals (FAs) alcohol ethers (FAEs). Weakly acidic APO-5 (Al/P = 1) exhibited excellent catalytic performance with 96 % FA yield in ethylene glycol, analysis acetalization reaction supported that adsorption catalyst sites co-catalyzed reaction. In addition, was sta...

BACKGROUND A reliable method for plasma would be useful to investigate the role of apolipoprotein (apo) AIV when associated with apo B-containing or triglyceride-rich lipoproteins. METHOD We used a sandwich ELISA to quantify lipoprotein B:AIV particles (Lp B:AIVf; lipoproteins containing at least apo B and apo AIV) in plasma. The method used microtiter plates coated with purified anti-apo B i...

The postprandial responses of apo B48, B100, E and lipids in triglyceride-rich lipoproteins (TRL) to a meal containing one-third of daily energy (39% fat calories) were compared in normolipidemic young men with apo E3/3 and apo E4/3 phenotypes. After the two groups consumed a diet rich in polyunsaturated fat for 15–29 d, their postabsorptive concentrations of TRL triglycerides, apo B48, and apo...

Serum concentrations of total cholesterol, triglycerides, and apolipoproteins (apo) A-I, B, CII, CIII, and E in 36 hemodialysis patients and nine anephric patients were compared with the concentrations in 34 normolipidemic subjects. The dialysis patients displayed a moderate hypertriglyceridemia (1.94 +/- 0.12 vs 1.09 +/- 0.11 mmol/L in controls, mean +/- SEM; P less than 0.001), apo CIII conce...

After in vitro incubation with radiolabeled amino acids, extracts of various chicken tissues were reacted with antiserum against apolipoprotein AI (apo-AI) of plasma high density lipoprotein. Radiolabeled apo-AI was found in liver and intestine as well as in the kidney and a variety of peripheral tissues including aorta, peripheral arteries, veins, and skeletal muscle. The immunoreactive apo-AI...

The results of this study indicate that very low density lipoprotein (VLDL) from the plasma of fasting normolipidemic or slightly hypertriglyceridemic subjects contains two apo B species. In SDS gel electrophoresis, the VLDL shows the presence of a major band corresponding to low density lipoprotein (LDL) apo B (apo B-100) and a minor band with the appropriate mobility of the lymph chylomicron ...

A glutamine/histidine polymorphism at residue 360 in apolipoprotein (apo) A-IV that generates two electrophoretically detectable isoforms, apo A-IV-1 and apo A-IV-2, affects the plasma concentration of lipoprotein(a) (Lp[a]) in a healthy population. To verify this unexpected association we analyzed the effect of the apo A-IV polymorphism on Lp(a) serum concentrations in 275 male coronary heart ...

OBJECTIVE Mechanisms underlying the cardiovascular risk of lipoprotein(a) are poorly understood. We investigated the relationship of apolipoprotein(a) (apo(a)) size, lipoprotein(a), and allele-specific apo(a) levels with HIV disease activity parameters in a biethnic population. METHODS AND RESULTS Lipoprotein(a) and allele-specific apo(a) levels were determined in 139 white and 168 black HIV-...

To investigate the prostaglandin 12 (PGI2) half-life regulated by high density lipoprotein (HDL) in patients with coronary artery disease (CAD), we determined the stability of PGI2 and serum apolipoprotein A-I (Apo A-I) and apolipoprotein A-II (Apo A-1I) levels in four age-matched groups of patients: controls (n=17), angina pectoris (n=18), unstable angina pectoris (n=17), myocardial infarction...

To study changes in the contents of plasma lipoproteins in human arteries with age and the relationship of lipoproteins with other arterial constituents, we analyzed the contents of apolipoproteins B (apo B) and A-I (apo A-I), free and esterified cholesterol, and glycosaminoglycans (GAG) in lesion-free aortic intimas of 30 children and adults. The content of apo B increased significantly with a...
