Obesity causes lipid accumulation in the heart and may lead to lipotoxic heart disease. Traditionally, the size of the cardiac triglyceride pool is thought to reflect the balance between uptake and beta-oxidation of fatty acids. However, triglycerides can also be exported from cardiomyocytes via secretion of apolipoproteinB-containing (apoB) lipoproteins. Lipoprotein formation depends on expres...

BACKGROUND/AIMS To analyze the effects of pomegranate juice (PJ) and punicalagin on macrophage triglyceride metabolism. METHODS Triglyceride metabolism was analyzed in PJ- or punicalagin-treated J774A.1 macrophages or in mouse peritoneal macrophages (MPM) harvested from C57BL/6 mice or from paraoxonase 2 (PON2)-deficient mice. RESULTS PJ (0-50 μM) significantly and dose-dependently decrease...

OBJECTIVE Hepatic triglyceride is closely associated with hepatic insulin resistance and is known to be decreased by thiazolididinediones. We studied the effect of pioglitazone on hepatic triglyceride content and the consequent effect on postprandial endogenous glucose production (EGP) in type 2 diabetes. RESEARCH DESIGN AND METHODS Ten subjects with type 2 diabetes on sulfonylurea therapy we...

Omega 3 fatty acids have healthcare benefits, but their absorption characteristics are not well defined, particularly for strategies to improve their bioavailability. We performed a double blind study comparing the bioavailability of 20% eicosapentaenoic acid in 4.5 grams of: natural triglyceride, reconstituted triglyceride, enzymatically synthesized triglyceride, monoglyceride and diglyceride....

OBJECTIVE Increased postprandial lipemia is part of diabetic dyslipidemia and is associated with accelerated atherosclerosis. We investigated the effects of the peroxisome proliferator-activated receptor-gamma agonist rosiglitazone on postprandial lipemia in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS A randomized, 8-week, crossover, placebo-controlled, double-blind trial was p...

The very low density lipoprotein receptor (VLDLR) has been proposed to play a role in the delivery of fatty acids to peripheral tissues. However, despite reduced adipose tissue mass in VLDLR-deficient (VLDLR(-)(/-)) mice, this has been difficult to substantiate. In the present study, VLDLR-deficient and VLDLR-overexpressing (PVL) mice were cross-bred onto a low density lipoprotein receptor knoc...

Objective: Prediabetes is an insulin resistance (IR) condition. The triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C) ratio and triglyceride-glucose (TyG) index were associated with prediabetes IR condition which are related to cardiovascular disease (CVD). High sensitive-CRP (hs-CRP) a marker of inflammation that closely CVD. aim this study determine the correlation between TG/HDL...

Lipase-modified pH-responsive poly(N-isopropylacrylamide)-based microgels were synthesized. An optical device was subsequently fabricated by sandwiching the enzyme loaded responsive microgels between two thin Au layers, and their response to triolein, a model triglyceride, was investigated. The device's response depended on the triglyceride concentration, demonstrating its potential application...

Sulphated zirconia, one of the most efficient solid acid catalysts, has been explored in present studies for transesterification reaction. The catalyst was synthesized by conventional precipitation method and characterized XRD, TGA, FTIR total acidity. exhibits excellent activity model triglyceride triacetin as well Jatropha oil with high selectivity towards formation monoalkyl esters. Influenc...
