Regulation of low density lipoprotein (LDL) receptor activity of cultured human skin fibroblasts was studied by measuring 4 degrees C binding of 125I-LDL after cells were incubated at 37 degrees C with medium containing varying lipoprotein and serum compositions. When cells grown on medium containing 10% human whole serum were exposed to medium containing 10% human lipoprotein-deficient serum, ...

APO-B merupakan apolipoprotein terbesar dari fraksi Very Low Density Lipoprotein (VLDL). Hipertrigliseridemia membuat hati memproduksi lebih banyak VLDL dan LDL kaya trigliserida yang akan dihidrolisis untuk menghasilkan padat kecil (sd-LDL) melalui Cholesterol ester transfer protein (CETP) lipase hati. Sekitar 90% adalah LDL, rasio K-LDL/APO-B sebagai indikator partikel LDL. Penelitian ini dil...

High cardiovascular risk conditions are frequently associated with altered plasma lipoprotein profile, such as elevated low-density lipoprotein (LDL) and LDL cholesterol and decreased high-density lipoprotein. There is, however, accumulating evidence that specific subclasses of LDL may play an important role in cardiovascular disease development, and their relative concentration can be regarded...

Results: Significant improvements occurred in blood pressure control for all adults (OR51.44) and those with hypertension (OR51.82), measures of total cholesterol (OR51.10) and high-density lipoprotein cholesterol (OR5 1.27) for all patients, and measure of lowdensity lipoprotein cholesterol (OR52.01) and blood pressure control (OR51.71) for patients with diabetes mellitus. Significant decline ...

Objective: Increased risk of atherosclerotic cardiovascular disease in subjects with type 2 diabetes is linked to elevated levels triglyceride-rich lipoproteins and their remnants. The metabolic effects PCSK9 (proprotein convertase subtilisin/kexin 9) inhibitors on this dyslipidemia were investigated using stable-isotope-labeled tracers. Approach Results: Triglyceride transport the metabolism a...

Background: Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are a new class of potent lipid-lowering drugs. Oxidized low-density lipoprotein (ox-LDL) is the key pathogenic factor leading to atherosclerosis. However, its effect on ox-LDL levels has not been clinically reported. For very high-risk Atherosclerotic cardiovascular disease (ASCVD) patients, guidelines propose stricte...

Small, dense, electronegative low density lipoprotein [LDL(-)] is increased in patients with familial hypercholesterolemia and diabetes, populations at increased risk for coronary artery disease. It is present to a lesser extent in normolipidemic subjects. The mechanistic link between small, dense LDL(-) and atherogenesis is not known. To begin to address this, we studied the composition and dy...

A Clinical Trial will test (1) a Self-Determination Theory (SDT) model of maintained smoking cessation and diet improvement, and (2) an SDT intervention, relative to usual care, for facilitating maintained behavior change and decreasing depressive symptoms for those who quit smoking. SDT is the only empirically derived theory which emphasizes patient autonomy and has a validated measure for eac...

Correlation between coronary heart disease and lipoprotein size and composition is well documented. Within the low-density lipoprotein (LDL) family the small LDL particles are associated with increased risk of coronary heart disease. These particles also have increased apolipoprotein (apo) B content. The appearance of these small LDL particles is the manifestation of complex alteration of plasm...

SUMMARY The cardiac lymphatic system of pigs was found to consist of valved efferent lymph vessels draining into a cardiac lymph node, which is similar to the lymphatic system found in dog and man. The interstitial lipoproteins of the heart were studied by sampling cardiac efferent lymph in anesthetized fasting pigs (n — 4) and dogs (n • • 5). In pigs, the lymph flow rate was 2.0 ± 0.7 ml/hr (m...
