Hypertension is a major risk factor for cardiovascular diseases in China; hence, identifying good serum markers might provide cost benefits in terms of reducing morbidity rates. In this population-based case-control study, participants were recruited from five districts in Hunan province, and 416 cases were matched with an equal number of controls. Markers related to elevated blood pressure were assessed: Body Mass Index, total cholesterol, triglycerides, fasting blood glucose, and creatinine. Three potential serum markers homocysteine (HCY), C-reactive protein (CRP), and alanine aminotransferase (ALT) were dichotomized as normal or high level...

HMG-CoA reductase inhibitors (statins) are the most effective pharmacological means of reducing cardiovascular disease risk. The most common side effect of statin use is skeletal muscle myopathy, which may be exacerbated by exercise. Hypercholesterolemia and training status are factors that are rarely considered in the progression of myopathy. The purpose of this study was to determine the extent to which acute and chronic exercise can influence statin-induced myopathy in hypercholesterolemic (ApoE-/-) mice...

Hyperhomocysteinemia (HHcy) is an independent risk factor for cardiovascular diseases, such as atherosclerosis. HHcy promotes atherogenesis by modifying the histone methylation patterns and miRNA regulation. In this study, we investigated the effects of homocysteine (Hcy) on the expression of enhancer of zeste homolog 2 (EZH2), and tested our hypothesis that Hcy-induced atherosclerosis is mediated by increased EZH2 expression, which is regulated by miR-92a. The levels of EZH2 and H3K27me3 were increased in the aorta of ApoE-/- mice fed a high-methionine diet for 16 weeks, whereas miR-92a expression was decreased...

To elucidate whether Sterol O-acyltransferase (Soat) mediates the absorption and transportation of yolk lipids to the developing embryo, zebrafish soat1 and soat2 were cloned and studied. In the adult zebrafish, soat1 was detected ubiquitously while soat2 mRNA was detected specifically in the liver, intestine, brain and testis. Whole mount in situ hybridization demonstrated that both soat1 and soat2 expressed in the yolk syncytial layer, hatching gland and developing cardiovascular as well as digestive systems, suggesting that Soats may play important roles in the lipid trafficking and utilization during embryonic development...

Low-density lipoproteins (LDLs) having various modifications are known to be atherogenic, i. e., possessing ability of inducing atherosclerosis. Circulating modified LDLs (cmLDLs) were found in blood of patients diagnosed with atherosclerosis confirmed angiographically. They appear to contain 2-3-fold less sialic acid as compared to LDLs in blood of apparently healthy people; cmLDLs differ by their physical properties: having higher density, smaller diameter, and greater electronegativity; by chemical properties: the amount of neutral sugars (N-acetyl-galactosamine, N-acetyl-glucosamine, galactose and glucose) in cmLSLs of patients with atherosclerosis is 1,5-2 times lower than in native lipoproteins, the levels of free and etherified cholesterol and triglycerides, monoglycerides and free fatty acids are higher, cmLDLs are oxidized and contain altered apolipoprotein B...

INTRODUCTION: Cardiovascular (CV) disease is a major cause of reduced life expectancy in type 1 diabetes (T1D). Intensive insulin therapy prevents CV complications but is constrained by hypoglycaemia and weight gain. Adjunct metformin reduces insulin dose requirement and stabilises weight but there are no data on its cardiovascular effects. AIMS: We have initiated an international double-blind, randomized, placebo-controlled trial (REMOVAL: REducing with MetfOrmin Vascular Adverse Lesions in type 1 diabetes) to examine whether metformin reduces progression of atherosclerosis in adults with T1D...

BACKGROUND & OBJECTIVES: Hepatic scavenger receptor class B1 (SR-B1), a high-density lipoprotein (HDL) receptor, is involved in the selective uptake of HDL-associated esterified cholesterol (EC), thereby regulates cholesterol homoeostasis and improves reverse cholesterol transport. Previously, we reported in euglycaemic obese rats (WNIN/Ob strain) that feeding of vitamin A-enriched diet normalized hypercholesterolaemia, possibly through hepatic SR-B1-mediated pathway. This study was aimed to test whether it would be possible to normalize hypercholesterolaemia in glucose-intolerant obese rat model (WNIN/GR/Ob) through similar mechanism by feeding identical vitamin A-enriched diet...

BACKGROUND & OBJECTIVES: The genesis of atherosclerotic lesions, a major cardiovascular risk factor starts in the early stage of life. If the premature development of cardiovascular risk factors can be anticipated during childhood, cardiovascular events can be prevented effectively by taking appropriate measures. This study was carried out to assess the role of in utero malnutrition in cardiovascular disease development by comparing cord blood lipid profiles and serum insulin levels between small-for-gestational-age (SGA) and appropriate-for-gestational-age (AGA) term newborns...

Special functionalization of semiconducting polymer dots (Pdots) is highly desired to expand their applications in chemo/biosening. Herein, carboxyl-functionalized poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-(1,4-benzo-{2,1',3}-thiadiazole)] dots covalently tagged with aminated β-cyclodextrin (NH2-CD) have been designed to construct a ratiometric sensor for cholesterol (Cho). Using CD-Pdots as energy donors with rhodamine B (RB) as energy acceptors, a fluorescence resonance energy transfer (FRET) pair has been built because the host-guest interaction between RB and CD attached to Pdots brings donors and acceptors into close proximity...

Omega-O-acylceramides (acylCer), a subclass of sphingolipids with an ultralong N-acyl chain (from 20 to 38 carbons, most usually 30 and 32 carbons), are crucial components of the skin permeability barrier. AcylCer are involved in the formation of the long periodicity lamellar phase (LPP, 12-13 nm), which is essential for preventing water loss from the body. Lower levels of acylCer and LPP accompany skin diseases, such as atopic dermatitis, lamellar ichthyosis, and psoriasis. We studied how the concentration and structure of acylCer influence the organization and permeability barrier properties of model lipid membranes...

The detailed structure of a nanogel formed by self-association of cholesterol-bearing pullulans (CHPs) was determined by contrast variation small-angle neutron scattering. The decomposition of scattering intensities into partial scattering functions of each CHP nanogel component, i.e., pullulan, cholesterol, and the cross-term between the pullulan and the cholesterol, allows us to investigate the internal structure of the nanogel. The effective spherical radius of the skeleton formed by pullulan chains was found to be 8...

We have developed a high resolution correlative method involving cryo-soft X-ray tomography (cryo-SXT) and stochastic optical reconstruction microscopy (STORM), which provides information in three dimensions on large cellular volumes at 70 nm resolution. Cryo-SXT morphologically identified and localized aggregations of carbon-rich materials. STORM identified specific markers on the desired epitopes, enabling colocalization between the identified objects, in this case cholesterol crystals, and the cellular environment...

Sulfated steroids can act as a latent form of active free steroids, coexisting with them in biological specimens. To evaluate the metabolic significance of free and sulfated steroid species, a simultaneous analysis of eight free steroids [cholesterol, pregnenolone, 17α-hydroxypregnenolone, progesterone, 17α-hydroxyprogesterone, dehydroepiandrosterone (DHEA), testosterone, and 17β-estradiol] and four biologically relevant sulfated steroids was developed and validated, using selected-ion and multiple-reaction monitoring modes coupled to polarity-switching liquid chromatography/mass spectrometry (LC/MS)...

In order to improve the chemical stability and antioxidant activity of (-)-epigallocatechin gallate (EGCG) in the gastrointestinal tract, niosomes composed of Tween-60 and cholesterol were developed to encapsulate EGCG in this investigation. EGCG loaded niosomes with encapsulation efficiency around 76% exhibited a small Z-average diameter about 60 nm. Compared to free EGCG, the EGCG remaining in dialysis tubes was significantly improved for niosomes at pH 2 and 7.4. Meanwhile, the residual EGCG for niosomes increased from 3% to 49% after 2 h incubation in simulated intestinal fluid (SIF)...
