background: studies demonstrated controversial results on subclinical hypothyroidism (sch) regarding lipid profile alteration with or without levothyroxine treatment. the purpose of this study is to investigate the effects of levothyroxine on serum lipids in sch. materials and methods: one hundred patients with sch referred to taleghani hospital in kermanshah were recruited and randomly assigne...
in india, the occurrence of diabetes mellitus is on increase and needs to be addressed properly. herbal remedies are considered most suitable for the management of type 2 diabetes due to their traditional acceptability and availability, low costs, and fewer side effects. traditionally bauhinia tomentosa l. (family- fabaceae) is used in the treatment of diabetes in india. aqueous extract and alc...
These studies were conducted to determine how plasma low density lipoprotein (LDL) cholesterol levels respond to dietary cholesterol, fed in increasing amounts with either corn oil or coconut oil diets, in high as compared to low LDL responding baboons; and to determine how apolipoprotein (apo) B transcription levels are modulated in response to dietary lipids. Eight high and eight low LDL resp...
BACKGROUND Increased nonfasting remnant cholesterol, like increased LDL cholesterol, is causally associated with increased risk for ischemic heart disease (IHD). We tested the hypothesis that extreme concentrations of nonfasting remnant and LDL cholesterol are equal contributors to the risk of IHD, myocardial infarction (MI), and all-cause mortality. METHODS We compared stepwise increasing co...
Incubation of cultured arterial smooth muscle cells with large concentrations of low density lipoproteins (LDL) resulted in a net increase in cell cholesterol and cholesteryl ester mass that was dependent on LDL concentration and time of incubation. Use of an inhibitor of acyl-CoA:cholesterol acyl-transferase (ACAT) reduced the accumulation of cholesteryl ester mass by 40% (range 25% to 50%), s...
Endocytosis of LDL and modified LDL represents regulated and unregulated cholesterol delivery to macrophages. To elucidate the mechanisms of cellular cholesterol transport and egress under both conditions, various primary macrophages were labeled and loaded with cholesterol or cholesteryl ester from LDL or acetylated low density lipoprotein (AcLDL), and the cellular cholesterol traffic pathways...
The mechanism(s) by which polyunsaturated fats reduce low density lipoprotein (LDL) cholesterol and apolipoprotein (apo) B were investigated in 20 cebus monkeys (Cebus albifrons) fed diets containing corn oil or coconut oil as fat (31% of calories) with or without dietary cholesterol (0.1% by weight) for 3 to 10 years. Coconut-oil feeding compared to corn-oil feeding resulted in significant inc...
Alcohol fed to rabbits in a liquid formula at 30% of calories increased plasma cholesterol by 36% in the absence of dietary cholesterol and by 40% in the presence of a 0.5% cholesterol diet. The increase was caused almost entirely by VLDL, IDL, and LDL. Cholesterol feeding decreased the fractional catabolic rate for VLDL and LDL apoprotein by 80% and 57%, respectively, and increased the product...
We have previously shown that in Hep G2 cells and human hepatocytes, as compared with fibroblasts, the low-density lipoprotein (LDL) receptor activity is only weakly down-regulated after incubation of the cells with LDL, whereas incubation with high-density lipoproteins (HDL) of density 1.16-1.20 g/ml (heavy HDL) strongly increased the LDL-receptor activity. To elucidate this difference between...
Using 2-16% gradient gel electrophoresis, we examined low density lipoprotein (LDL) particle size in relation to plasma lipoproteins in 1,168 women and 1,172 men from the Framingham Offspring Study. In addition, we studied the effect of dietary intake on LDL size in a subset of the population. Seven LDL size peaks were identified, with the largest, LDL 1, being found in the density range 1.019-...
