In this study, we investigated the toxicity and biological activity of a novel triazine ring compound named magnolol derivative 568 (MD568). The LD50 of MD568 was determined in Sprague-Dawley (SD) rats by intraperitoneal injection. Treatment of high fat diet-induced obese rats with MD568 demonstrated that MD568 displayed significant anti-obesity effects. MD568 markedly reduced body weight, blood lipid contents, white adipose tissue (WAT) and liver mass in obese rats. In addition, MD568 modulated lesions in WAT through regulating PPAR-Ɣ, C/EBP-a, SREBP-1c and FABP-4 proteins in the liver through regulating PPAR-α, SREBP-1c and FABP-4...

To study the roles of hypervariable regions (HVRs) in receptor-binding subunit S1 of the spike protein, we manipulated the genome of the IBV Beaudette strain using a reverse genetics system to construct seven recombinant strains by separately or simultaneously replacing the three HVRs of the Beaudette strain with the corresponding fragments from a QX-like nephropathogenic isolate ck/CH/LDL/091022 from China. We characterized the growth properties of these recombinant IBVs in Vero cells and embryonated eggs, and their pathogenicity, tropism, and serotypes in specific pathogen-free (SPF) chickens...

Background: Obesity and metabolic syndrome (MetS) are major risk factors for atherosclerotic diseases; however, a causal link remains elusive. Animal models resembling human MetS and its complications, while important, are scarce. We aimed at developing a porcine model of human MetS. Methods: Forty pigs with familial hypercholesterolemia were fed a high fat + fructose diet for 30 weeks. Metabolic assessments and subcutaneous fat biopsies were obtained at 18 and 30 weeks, and fat distribution was assessed by CT-scans...

Endothelial dysfunction (ED) and oxidative stress are potential new pathomechanisms of cardiovascular diseases in patients with chronic kidney disease (CKD). The aim of the study was to assess the association between endothelial dysfunction, oxidative stress biomarkers, and cardiovascular risk factors in children with CKD. Serum oxidized LDL (oxLDL), protein carbonyl group, urea, creatinine, cystatin C, thrombomodulin, asymmetric dimethylarginine (ADMA), von Willebrand factor, brain natriuretic peptide (BNP), lipids, high sensitivity C-reactive protein, intercellular adhesion molecule-1 levels, and albuminuria were measured...

Background: Little is known about the association of the protein phosphatase 1 regulatory subunit 3B gene ( PPP1R3B ) single nucleotide polymorphisms (SNPs) and serum lipid levels, the risk of coronary artery disease (CAD) and ischemic stroke (IS) in the Chinese populations. This study detected such association in a Southern Chinese Han population. Methods: Genotypes of 4 novel PPP1R3B SNPs (rs12785, rs330910, rs330915 and rs9949) in 1704 Han Chinese (CAD, 556; IS, 531 and control, 617) were determined by the Snapshot technology...

In order to calculated-measure the low-density lipoprotein cholesterol (LDL-C), the Friedewald formula is used. LDL can be calculated by Friedewald formula in this way: total cholesterol (TC) minus high-density lipoprotein (HDL)-cholesterol minus triglycerides (TG)/5 in milligrams per deciliter. In the article entitled "Agmatine protects rat liver from nicotine-induced hepatic damage via antioxidative, antiapoptotic, and antifibrotic pathways" published in the same journal (Vol, 389, pp. 1341-1351), LDL-C has been calculated in this way: LDL-C = TC - [HDL-C - (TG/5)] which is not in accordance with the Friedewald formula and thus the result is false...

BACKGROUND AND AIMS: Limited data is available on the factors influencing the lipid profiles and the prevalence of dyslipidemia in children, adolescents and young adults with type 1 diabetes. We aimed at assessing the influences of metabolic control and ApoE genotypes on lipid profiles and the prevalence of dyslipidemia in children, adolescents and young adults with type 1 diabetes. METHODS: Children, adolescents and young adults with type 1 diabetes from our nationwide cohort attending the annual check-up were prospectively included...

Reduced cellular response to insulin in skeletal muscle is one of the major components of the development of type 2 diabetes (T2D). Mitochondrial dysfunction involves in the accumulation of toxic reactive oxygen species (ROS) that leads to insulin resistance. The aim of this study was to verify the involvement of mitochondrial DNA damage at ROS generation in skeletal muscle during development of T2D. Wistar rats were fed a diet containing 60% fat over 8 weeks and at day 14 a single injection of STZ (25 mg/kg) was administered (T2D-induced)...

BACKGROUND: Hypertension (HTN), dyslipidemia and hyperglycemia are major risk factors for cardiovascular disease, accounting for the highest morbidity and mortality among the elderly Jordanian population. This study aimed to evaluate serum lipid and glucose profiles of hypertensive patients and normotensive controls, and determine the risk factors for HTN among elderly population in Jordan. METHODS: A cross-sectional study was carried out among 200 participants, including 111 hypertensive patients and 89 normotensive controls from June to October 2017 in North Jordan...

BACKGROUND AND AIMS: Dyslipidemia in HIV-infected patients is unique and pathophysiologically associated with host factors, HIV itself and the use of antiretroviral therapy (ART). The use of nuclear magnetic resonance spectroscopy (NMR) provides additional data to conventional lipid measurements concerning the number of lipoprotein subclasses and particle sizes. METHODS: To investigate the ability of lipoprotein profile, we used a circulating metabolomic approach in a cohort of 103 ART-naive HIV-infected patients, who were initiating non-nucleoside analogue transcriptase inhibitor (NNRTI)-based ART, and we subsequently followed up these patients for 36 months...

Importance: Effects on specific fatal and nonfatal end points appear to vary for low-density lipoprotein cholesterol (LDL-C)-lowering drug trials. Objective: To evaluate whether baseline LDL-C level is associated with total and cardiovascular mortality risk reductions. Data Sourcesand Study Selection: Electronic databases (Cochrane, MEDLINE, EMBASE, TCTMD, ClinicalTrials.gov, major congress proceedings) were searched through February 2, 2018, to identify randomized clinical trials of statins, ezetimibe, and PCSK9-inhibiting monoclonal antibodies...

Gestational diabetes mellitus (GDM) has short- and long- term influence on pregnant women and fetus. Swimming, as an aerobic exercise, can effectively improve the blood glucose level in GDM, but the effect of mild swimming alone was not very substantial. Metformin, as an oral antidiabetic drug, has obvious hypoglycemic effect, and is economic also, but the long-term effect on pregnant women and fetus has not been completely clear. We hypothesize that combined intervention of mild swimming and low dose of metformin, may effectively reduce blood glucose, improve the pregnancy outcomes in GDM dams, but simultaneously avoiding the adverse effects caused by overdose of drug and impotence of mild swimming...

To observe the protective effect of Longxue Tongluo capsule (LTC) on human umbilical vein endothelial cells (EAhy.926 cells) injury induced by oxidized low-density lipoprotein (ox-LDL, 100 mg·L⁻¹). The effect of the cell viability of LTCin alleviating OX-LDL-induced endothelial cell injury was determined by MTT and LDH assay. The effect of LTC on lactic dehydrogenase (LDH), nitric oxide (NO), super oxide dlsmutase (SOD) and malondialdehyde (MDA) levels were detected by corresponding assay kits according to manufacturer's instruction...

The present study investigates the potential therapeutic mechanism underlying the effects of the Chinese herbal formula Hongqijiangzhi Fang (HJF) on nonalcoholic fatty liver disease (NAFLD) in rats. Male Sprague Dawley (SD) rats were randomly divided into 4 groups ( n = 8): control group was fed a normal diet, three other groups were fed high-fat diets (HFD), and the two treatment groups were intragastrically given a compound probiotic or HJF during the molding time. After 16 w, related indices were detected...

PURPOSE: Hypertension and dyslipidemia are 2 risk factors of cardiovascular disease that often present simultaneously. Traditionally, treatment of these multiple conditions required separate medications for each disease, which may result in poor compliance and thus lead to possible treatment failure. Fixed-dose combination (FDC) therapy with a single pill may be a solution in these situations. METHODS: This multicenter, 8-week, randomized, double-blind, Phase III study evaluated the efficacy and safety of FDC treatment with telmisartan (80 mg) and rosuvastatin calcium (20 mg) in Korean patients with mild to moderate hypertension and dyslipidemia...
