Male hamsters (116.5 ± 2.16 g) were fed with the AIN 93G diet containing casein (20%), coconut fat (13.5%) and cholesterol (0.1%). The animals were divided into four groups: normolipidemic control (stan...

Time Trends in Age at Menarche and Related Non-Communicable Disease Risk during the 20th Century in Mexico.

Developed countries have shown a time trend towards a younger age at menarche (AAM), which is associated with increased risk of later obesity and non-communicable diseases. This study aimed to assess whether a time trend in AAM is associated with disease risk in Mexican women ( = 30,826), using data from the Mexican National Health Survey (2000). Linear and log binomial regression was used for nut...

Simvastatin promotes restoration of chondrocyte morphology and phenotype.

In this study we examined whether the action of simvastatin affects re-differentiation of passaged chondrocytes and if so, whether this was mediated via changes in cholesterol or cholesterol intermediates. Bovine articular chondrocytes, of varying passage number, human knee chondrocytes and rat chondrosarcoma chondrocytes were treated with simvastatin and examined for changes in mRNA and protein e...

Inhibition of PRMT3 activity reduces hepatic steatosis without altering atherosclerosis susceptibility in apoE knockout mice.

The nuclear receptor liver X receptor (LXR) impacts on cholesterol metabolism as well as hepatic lipogenesis via transcriptional regulation. It is proposed that inhibition of the protein arginine methyltransferase 3 (PRMT3) uncouples these two transcriptional pathways in vivo by acting as a specific lipogenic coactivator of LXR. Here we validated the hypothesis that treatment with the allosteric P...

Very high high-density lipoprotein cholesterol is associated with increased all-cause mortality in South Koreans.

Our study aimed to investigate the association between high-density lipoprotein cholesterol (HDL-C) and all-cause and cause-specific mortality in Korean adults.

Caveolins; An Assailant or An Ally of Various Cellular Disorders.

Caveolae have impressive morphological highlights of the cytomembrane of mammalian cells which involve in wide diversity of cellular functions involving signaling pathways and cholesterol hastening. Caveolin proteins possess a 'scaffolding' domain which for caveolin-1 and caveolin-3 appear to act a dominant role in signal regulation through caveolae. Caveolin-1 is treated to be protein in the cyto...

Association of total cholesterol with severe acute pancreatitis: A U-shaped relationship.

There is no consensus on relationship between total cholesterol levels and incidence of severe acute pancreatitis (SAP). The aim of this study was to investigate the relation between total cholesterol (TC) and the disease severity of acute pancreatitis.

SLC22A3 is associated with lipoprotein (a) concentration and cardiovascular disease in familial hypercholesterolemia.

Several clinical and genetic factors have been shown to modulate the cardiovascular risk in subjects affected by familial hypercholesterolemia (FH). Genome wide association studies (GWAS) in the general population have identified several single nucleotide polymorphisms (SNPs) significantly associated with the risk of cardiovascular disease (CVD). This include the rs2048327 variant in the SLC22A3 g...

PEO-b-PCL grafted niosomes: The cooperativilty of amphiphilic components and their properties in vitro and in vivo.

Niosomes belong to drug delivery systems and consist mainly of non-ionic surfactants and cholesterol. In this study, we designed and developed systems composed of non-ionic surfactants i.e. Tween 80, Span 80 and cholesterol with and without poly(ethylene oxide)-b-poly(ε-caprolactone) (PEO-b-PCL) block copolymer, using different molar ratios of the above components. The nanosystems were formed by ...

Effects of gemfibrozil on sex hormones and reproduction related performances of Oryzias latipes following long-term (155 d) and short-term (21 d) exposure.

Gemfibrozil, a lipid-regulating pharmaceutical, has been widely used for treating dyslipidemia in humans and detected frequently in freshwater environments. Since plasma cholesterol is a precursor of steroid hormones, the use of gemfibrozil may influence the sex hormone balances. However, its endocrine toxicity following long-term exposure is not well understood. The purpose of the present study i...

Alpha-cyclodextrin inhibits cholesterol crystal-induced complement-mediated inflammation: A potential new compound for treatment of atherosclerosis.

Cholesterol crystal (CC)-induced inflammation is a critical step in the development of atherosclerosis. CCs activate the complement system and induce an inflammatory response resulting in phagocytosis of the CCs, production of reactive oxygen species (ROS) and release of cytokines. The cyclodextrin 2-hydroxypropyl-β-cyclodextrin has been found to reduce CC-induced complement activation and induce...

HDL cholesterol and ASCVD risk stratification: A debate.

This debate is designed to review the usefulness of the cholesterol mass within high-density lipoproteins (HDL-C) to predict the risk of atherosclerotic cardiovascular disease (ASCVD). PRO: There is much current confusion regarding the role of high density lipoproteins (HDLs) in atherosclerotic cardiovascular disease (ASCVD). While it is an established fact that the concentration of HDL cholestero...

Serum TSH level in obese children and its correlations with atherogenic lipid indicators and carotid intima media thickness.

Moderately elevated level of thyroid-stimulating hormone accompanied by normal serum concentrations of free thyroxine, suggesting subclinical hypothyroidism, is the most common hormonal abnormality in obese children. Controversy remains, whether a thyroid dysfunction related to obesity has an influence on the cardiovascular risk factors. The aim of the study was to assess correlation between thyro...

Plasma LDL-Cholesterol Level at Admission is Independently Associated with Infarct Size in Patients with ST-Segment Elevation Myocardial Infarction Treated with Primary Percutaneous Coronary Intervention.

Hypercholesterolemia is a well-known risk factor for developing atherosclerosis and subsequently for the risk of a myocardial infarction (MI). Moreover, it might also be related to the extent of damaged myocardium in the event of a MI. The aim of this study was to evaluate the association of baseline low density lipoprotein-cholesterol (LDL-c) level with infarct size in patients with ST-segment el...

Association of the Serum Total Cholesterol to Triglyceride Ratio with Diabetic Retinopathy in Chinese Patients with Type 2 Diabetes: A Community-Based Study.

The relationship of total cholesterol (TC) or triglyceride (TG) to diabetic retinopathy (DR) has proven difficult to determine. In addition, there is no report of any study of the correlation between the TC/TG ratio and DR. This study was therefore undertaken to investigate the relationship between the TC/TG ratio and DR in Chinese adults with type 2 diabetes mellitus.
