DRL-17822 is a novel selective cholesteryl ester transfer protein inhibitor that showed an increased exposure, including an increase of >20-fold of maximum concentration and area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration, following a high-fat breakfast using a nanocrystal formulation. To reduce this effect of food, we generated an amorphous solid dispersion formulation. In this study, we compared the food effect of both formulations of DRL-17822 in a 2-part randomized, open-label, 4-way crossover study involving healthy adult males 18-45 years of age. In both parts of the study, 12 subjects received both formulations of DRL-17822 in both the fasted and fed states; a low-fat breakfast was provided in the first part and a high-fat breakfast in the second part. Compared to the nanocrystal formulation, the amorphous solid dispersion formulation substantially increased DRL-17822 exposure in the fasted state, including increased maximum concentration, area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration, and area under plasma concentration-time curve from time zero to infinity. Following a high-fat breakfast, DRL-17822 exposure was increased to a lesser extent in the amorphous solid dispersion formulation compared to the nanocrystal formulation (P < .001). Moreover, compared to the nanocrystal formulation the amorphous solid dispersion formulation caused a more pronounced increase in high-density lipoprotein in the fasted state. Consuming breakfast increased the effect of DRL-17822 on high-density lipoprotein. Taken together, our results indicate that by improving its formulation, DRL-17822 has a favorable exposure profile and therefore a more predictable food effect profile. Show less

Cholesteryl ester transfer protein (CETP) plays an important role in lipoprotein metabolism. Previous studies have suggested that the CETP TaqI B1/B2 allele is associated with the risk of venous thrombosis (VT). To investigate the associations between genetically determined CETP concentrations and 22 hemostatic factors in healthy individuals, and the risk of a first VT event, in a large VT case-control study. Analyses were performed in the Multiple Environmental and Genetic Assessment of Risk Factors for Venous Thrombosis (MEGA) case-control study. CETP unweighted/weighted genetic risk scores (GRSs) were derived from three single-nucleotide polymorphisms that were identified from a recent genome-wide association study on serum CETP concentrations. The associations between CETP GRSs and 22 hemostatic factors (procoagulant/anticoagulant and fibrinolytic factors) were assessed by linear regression from an additive model in controls (n = 2813). The associations between CETP GRSs and the risk of a first VT were assessed by logistic regression analyses in 3950 VT cases and 4765 controls. In the controls (median age, 49 years; 53% women), both unweighted and weighted GRSs showed that factor VII activity was negatively associated with the genetically determined CETP concentration (weighted GRS β -3.08 IU/dL per μg/mL genetically determined CETP, 95% confidence interval -5.73 to -0.42). No association was observed with the risk of a first VT. Genetically determined CETP concentrations only showed a weak negative association with factor VII activity. However, this did not lead to an association with the risk of a first VT. Show less

To describe the surgical placement of a continuous extraluminal tracheal prosthesis (CETP) and report the subsequent postoperative clinical outcomes in dogs with tracheal collapse. Retrospective case series. Fifty-four dogs. Medical records of dogs in which cervical and/or thoracic inlet tracheal collapse was diagnosed and treated by placement of a CETP between 2010 and 2017 were reviewed to evaluate postoperative complications, changes in respiratory function, and survival. Histological examinations of tracheal tissues performed in 2 dogs at 51 and 57 months after surgery were also reviewed. Fifty-three (98%) dogs survived to discharge. Postoperative complications included laryngeal paralysis (1 dog), disseminated intravascular coagulation (1 dog), and recurrent tracheal collapse (2 dogs). None of the dogs exhibited clinical evidence of tracheal necrosis. Preoperative dry, harsh cough resolved in 87% of the dogs after surgery. Goose honking cough was resolved in 25 of 26 (96%) dogs. Median follow-up time was 30 months (range, 16 days to 76 months). The survival rate at 36 months was 86% (CI: 75%-96%). On histological examination in 2 dogs, the tracheal tissue surrounding the prosthesis was well preserved and without evidence of chronic inflammation. Continuous extraluminal tracheal prosthesis placement in dogs with tracheal collapse resulted in low postoperative complication rates and good long-term outcomes. Continuous extraluminal tracheal prosthesis placement provides a viable alternative surgical option for managing dogs with tracheal collapse. Show less

Activated sludge, a microbial ecosystem at industrial wastewater treatment plants, is an active collection of diverse gene pool that creates the intelligence required for coexistence at the cost of pollutants. This study has analyzed one such ecosystem from a site treating wastewater pooled from over 200 different industries. The metagenomics approach used could predict the degradative pathways of more than 30 dominating molecules commonly found in wastewater. Results were extended to design a bioremediation strategy using 4-methylphenol, 2-chlorobenzoate, and 4-chlorobenzoate as target compounds. Catabolic potential required to degrade four aromatic families, namely benzoate family, PAH family, phenol family, and PCB family, was mapped. Results demonstrated a network of diverse genera, where a few phylotypes were seen to contain diverse catabolic capacities and were seen to be present in multiple networks. The study highlights the importance of looking more closely at the microbial community of activated sludge to harness its latent potential. Conventionally treated as a black box, the activated biomass does not perform at its full potential. Metagenomics allows a clearer insight into the complex pathways operating at the site and the detailed documentation of genes allows the activated biomass to be used as a bioresource. Show less

High lipoprotein(a) levels are observationally and causally, from human genetics, associated with increased risk of cardiovascular disease including myocardial infarction and aortic valve stenosis. The European Atherosclerosis Society recommends screening for elevated lipoprotein(a) levels in high-risk patients. Different therapies have been suggested and some are used to treat elevated lipoprotein(a) levels such as niacin, PCSK9 inhibitors, and CETP inhibitors; however, to date, no randomized controlled trial has demonstrated that lowering of lipoprotein(a) leads to lower risk of cardiovascular disease. Synthetic oligonucleotides can be used to inactivate genes involved in disease processes. To lower lipoprotein(a), two antisense oligonucleotides have been developed, one targeting apolipoprotein B and one targeting apolipoprotein(a). Mipomersen is an antisense oligonucleotide targeting apolipoprotein B and thereby reducing levels of all apolipoprotein B containing lipoproteins in the circulation. Mipomersen has been shown to lower lipoprotein(a) by 20-50% in phase 3 studies. AKCEA-APO(a)-L Show less

Low high-density lipoprotein cholesterol (HDL-C) is a major risk factor for cardiovascular diseases (CVDs), the leading cause of global mortality. We aimed to determine the effect of coffee drinking and sex and their interaction, as well as rs1800588 and rs1800775 polymorphisms on HDL-C levels in Taiwanese adults. Data of 4262 men and 4813 women, aged 30-70 years, were retrieved from Taiwan Biobank. The interaction between sex and coffee drinking on HDL-C was significant ( Show less

Experimental and epidemiological studies show that bergamot polyphenolic fraction (BPF) ameliorates the serum lipemic profile, normalizes blood pressure and improves non alcoholic fatty liver disease in patients suffering from metabolic syndrome. Despite this evidence, the molecular mechanisms responsible for these beneficial effects remain unclear. The aim of our study is to clarify the effects of BPF on the lipoprotein assembly and to identify oxidative stress biomarkers correlating hyperlipidaemia and BPF-induced metabolic changes. Male Wistar rats (180-200 g) were randomly assigned to receive a standard diet, a hypercholesterolemic diet or a hypercholesterolemic diet+BPF (20 mg/Kg/rat daily, gavage), respectively, for 90 days. Total cholesterol (tChol), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides (TG) and fasting plasma glucose were evaluated at the baseline as well as at the end of the treatment. To assess the effect of BPF on the Lipid Transfer Protein System, detection of ACAT, LCAT, CETP, PON1, Apo A1 and Apo B have also been carried out. Finally, the lipid peroxidation biomarker (TBARS) and oxyLDL were also measured. BPF prevented tChol, LDL-C, TG and fasting plasma glucose enhancement and improved HDL-C. Treatment of hyperlipæmic rats with BPF significantly restored altered the serum concentration of lipemic biomarkers and the activity of ACAT, LCAT, CETP and PON1, an effect accompanied by the concomitant normalization of Apo A1 and APO B levels. In addition, TBARS levels were reduced significantly by the treatment with BPF. BPF prevents diet-induced alteration of the lipid profile in rats, counteracting oxidative stress and improving the dysregulation of the Lipid Transfer Protein System. These data add new insights into the molecular mechanisms underlying the beneficial role of BPF in the therapy of hyperlipidaemia, thus suggesting a novel approach in the prevention of cardiovascular disease.

Atherosclerosis is the main cause of stroke, and dyslipidemia is the most important risk factor for atherosclerosis. In this paper, pharmacophore and molecular docking models of eight key lipid-lowering targets, namely NPC1 L1, HMG-CoA reductase, SQS, MTP, CETP, PPARα, LXRα and LXRβ, were used to screen out the small molecular database of traditional Chinese medicine(TCM), which was made up of ingredients of thirteen Chinese herbal medicines contained in Xixian Tongshuan Preparation. The screening results indicated that the preparation could showed an effect in regulating lipid on target NPC1 L1, HMG-CoA reductase, LXRβ and SQS through four groups of potential active compounds, namely prupersin A in peach kernel and suffruticoside A in gastrodiaelata, limocitrin-β-D-glucoside in Ligusticum chuanxiong, 2'-(2,3-dihydroxybenzoyl)-sweroside in Pinellia ternate and quercitrin in Panax notoginseng, 4-tert-butyl-2-[(5-tert-butyl-2-hydroxy-phenyl)methoxy-methyl]-6-(hydroxymethyl)phenol in Gastrodia elata. Moreover, the properties and extraction process of the most potentialactive compounds were consistent with the preparation process of Xixian Tongshuan Capsules, which indicated that the capsule had more advantages than the pill in the existing two dosage forms of Xixian Tongshuan Preparation. This study analyzed the pharmacodynamic basis and mechanism of Xixian Tongshuan Capsules in regulating lipid for treating stroke, and provided evidence for its further research and clinical application.

Cholesteryl ester transfer protein (CETP) inhibitor-mediated induction of HDL-cholesterol has no effect on the protection from cardiovascular disease (CVD). However, the mechanism is still unknown. Data on the effects of this class of drugs on subclasses of HDL are either limited or insufficient. In this study, we investigated the effect of evacetrapib, a CETP inhibitor, on subclasses of HDL in patients with atherosclerotic cardiovascular disease or diabetes. Baseline and 3-month post-treatment samples from atorvastatin 40 mg plus evacetrapib 130 mg (n = 70) and atorvastatin 40 mg plus placebo (n = 30) arms were used for this purpose. Four subclasses of HDL (large HDL, medium HDL, small HDL, and preβ-1 HDL) were separated according to their size and quantified by densitometry using a recently developed native polyacrylamide gel electrophoresis (PAGE) system. Relative to placebo, while evacetrapib treatment dramatically increased large HDL and medium HDL subclasses, it significantly reduced small HDL (27%) as well as preβ-1 HDL (36%) particles. Evacetrapib treatment reduced total LDL, but also resulted in polydisperse LDL with LDL particles larger and smaller than the LDL subclasses of the placebo group. Evacetrapib reduced preβ-1 HDL and small HDL in patients with ASCVD or diabetes on statin. Preβ-1 HDL and medium HDL are negatively interrelated. The results could give a clue to understand the effect of CETP inhibitors on cardiovascular outcomes. Show less

Cholesterol ester transfer protein (CETP) is responsible for the transformation of high density lipoprotein (HDL) to low density lipoprotein (LDL) and is a risk factor for atherosclerosis. Our study investigated the association of the rs5883 CETP gene polymorphism with HDL and LDL levels, in 45 coronary artery disease patients and 45 control patients. CETP gene polymorphism was detected using Real Time-Polymerase Chain Reaction (RT-PCR). Lipoprotein levels were measured using Quantimetrix system. There were lack of associaition regarding CETP polymorphism in atherosclerosis and HDL and LDL levels (p>0.05) BMI was higher among coronary artery disease patients (CADP) compared to the control group (28.97±6.38, 26.52±4.39 respectively, p<0.03). Frequency of CADP (82.6 %, n=19) who were taking treatment was higher (17.4 %, n=4) (p<0.00). The frequencies of hypertension and type-2 diabetes were higher among CADP (p<0.00). Families of CADP have more CADP (p<0.02). Small HDL particle levels were higher in the control group (p<0.00). In Turkey, BMI, and frequencies of hypertension and type-2 diabetes were higher among CADP than among healthy controls. Furthermore, the genotypes of the rs5883 CETP gene polymorphism did not differ between CADP and healthy controls. Show less

Long-term exposure to excess dietary fat leads to obesity and the metabolic syndrome (MetS). The purpose of the present study was to identify global changes in liver gene expression and circulating miRNAs in a humanized mouse model of diet-induced MetS. Male apoE3L.CETP mice received a high-fat diet (HFD) or a low-fat diet (LFD) for different time periods and the progression of MetS pathology was monitored. A separate group of mice was divided into responders (R) or nonresponders (NR) and received HFD for 16 weeks. We found that mice receiving the HFD developed manifestations of MetS and displayed an increasing number of differentially expressed transcripts at 4, 8, and 12 weeks compared with mice receiving the LFD. Significantly changed genes were functionally annotated to metabolic diseases and pathway analysis revealed the downregulation of genes in cholesterol and fatty acid biosynthesis and upregulation of genes related to lipid droplet formation, which was in line with the development of hepatic steatosis. In the serum of the apoE3L.CETP mice we identified three miRNAs that were upregulated specifically in the HFD group. We found that responder mice have a distinct gene signature that differentiates them from nonresponders. Comparison of the two diet intervention studies revealed a limited number of common differentially expressed genes but the expression of these common genes was affected in a similar way in both studies. In conclusion, the characteristic hepatic gene signatures and serum miRNAs identified in the present study provide novel insights to MetS pathology and could be exploited for diagnostic or therapeutic purposes.

Lipoprotein (a) [Lp(a)] has recently emerged as a causal, independent and genetic risk factor for cardiovascular disease and calcific aortic valve disease. Given the high incidence of elevated Lp(a) among the general population, significant gaps in the knowledge of Lp(a) biology, pathophysiology and current therapies affecting Lp(a) reduction exist. As plasma Lp(a) levels are genetically determined and insensible to diet, exercise and lifestyle changes, lipid-lowering therapies seem to be the solution to lower elevated Lp(a) levels. This review summarises the current knowledge of Lp(a) structure, metabolism, catabolism, pathophysiology, and Lp(a) response to statins, lipid apheresis, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, cholesterol esterase transferase protein (CETP) inhibitors and antisense oligonucleotides (ASOs).

The impact of cholesteryl ester transfer protein (CETP) on atherosclerotic development in humans remains unclear. Plasma cholesteryl ester transfer was shown to be associated with carotid intima-media thickness in type 2 diabetic (T2D) patients with adequate metabolic control. Since glycation of CETP may influence cholesteryl ester transfer processes, it is important to determine if plasma cholesteryl ester transfer is still a determinant of carotid intima-media thickness (IMT) in patients with poorly controlled diabetes. The aim of the present study was to determine whether CETP activity influences carotid IMT in T2D patients with poor metabolic control. In 110 individuals with T2D, we measured CETP mass concentration with ELISA, CETP activity with a radioactivity method and carotid intima-media thickness with high-resolution real-time B-mode ultrasonography. The mean HbA1C was 8.8 ± 1.7%. Carotid IMT did not correlate with CETP activity in the total population. In T2D patients with HbA1C < 8% (n = 33), mean HbA1C was 6.9% and the correlation between carotid IMT and CETP activity was not significant (p = 0.09). In a multivariable analysis that included the total population, carotid intima-media thickness was positively associated with diabetes duration (p = 0.02) but not with CETP activity or HbA1C. We observed no correlation between carotid intima-media thickness, a marker of early atherosclerosis, and CETP activity in T2D patients with poor metabolic control. Disease duration, which reflects accumulated metabolic abnormalities, may have blunted the potential effect of CETP on atherosclerosis. Metabolic control appears essential to determine the pro- or anti-atherogenic influence of CETP in patients with T2D. Show less

Reverse Cholesterol Transport (RCTr) is the mechanism by which excess cholesterol from peripheral tissues is transported to the liver for hepatobiliary excretion, thereby inhibiting foam cell formation and the development of atherosclerosis. Exercise affects RCTr, by influencing high-density lipoprotein cholesterol (HDL) through remodeling and by promoting hepatobiliary sterol excretion. The objectives of this systematized review of animal studies is to summarize the literature and provide an overview of the effects of chronic exercise (at least two weeks) on apolipoproteins (Apo A-I, Apo-E), Paraoxonase-1 (PON1), ATP-binding cassette transporters (ABCA1, ABCG1, ABCG4, ABCG5, ABCG8), scavenger receptor class B type I (SR-BI), cholesteryl ester transfer protein (CETP), low-density lipoprotein receptor (LDLr) and cholesterol 7 alpha-hydroxylase (CYP7A1) and Niemann-Pick C1-like 1 (NPC1L1). Three electronic databases (PubMed, Science Direct and Google Scholar) were searched for eligible studies conducted from the earliest available date to August 2018. Most of studies investigate the effects of low to moderate intensity aerobic training on RCTr elements. The majority were on exercised rats undertaking moderate intensity aerobic training. This review highlights that moderate intensity and longer-term training has a greater effect on RCTr elements than low intensity training. There a few studies examining high intensity training which warrants further investigation. Show less

Lipids foster energy production and their altered levels have been coupled with metabolic ailments. Indians feature high prevalence of metabolic diseases, yet uncharacterized for genes regulating lipid homeostasis. We performed first GWAS for quantitative lipids (total cholesterol, LDL, HDL, and triglycerides) exclusively in 5271 Indians. Further to corroborate our genetic findings, we investigated DNA methylation marks in peripheral blood in Indians at the identified loci (N = 233) and retrieved gene regulatory features from public domains. Recurrent GWAS loci-CELSR2, CETP, LPL, ZNF259, and BUD13 cropped up as lead signals in Indians, reflecting their universal applicability. Besides established variants, we found certain unreported variants at sub-genome-wide level-QKI, REEP3, TMCC2, FAM129C, FAM241B, and LOC100506207. These variants though failed to attain GWAS significance in Indians, but largely turned out to be active CpG sites in human subcutaneous adipose tissue and showed robust association to two or more lipid traits. Of which, QKI variants showed significant association to all four lipid traits and their designated region was observed to be a key gene regulatory segment denoting active transcription particularly in human subcutaneous adipose tissue. Both established and novel loci were observed to be significantly associated with altered DNA methylation in Indians for specific CpGs that resided in key regulatory elements. Further, gene-based association analysis pinpointed novel GWAS loci-LINC01340 and IQCJ-SCHIP1 for TC; IFT27, IFT88, and LINC02141 for HDL; and TEX26 for TG. Present study ascertains universality of selected known genes and also identifies certain novel loci for lipids in Indians by integrating data from various levels of gene regulation. Show less

Recent genome-wide association studies (GWAS) have identified several genetic variants that influence the risk of dyslipidemia and coronary artery disease (CAD). In this study, we have examined the potential association of five SNPs variants related to lipid pathway, previously identified in GWAS studies (ZNF259 C>G, CETP I405VA/G, LPA C>T, LPLS447X and PSRC1 A>G) with CAD. Two hundred and ninety subjects including 194 patients with coronary artery disease and 96 controls were enrolled, followed by the analyses of anthropometric/biochemical parameters. Genotyping was carried out using Taq-Man real-time PCR based method. The association of the genetic polymorphisms with CAD was determined using univariate and multivariate analyses. CAD patients had a higher (p < 0.05) fasting blood glucose (FBG), total cholesterol (TC), high sensitivity C-reactive protein (hs-CRP), low-density lipoprotein cholesterol (LDL-C) and waist circumference. Results showed that subjects with CETP rs5882 genetic variant, AA&AG genotypes, had a higher risk of developing Coronary artery disease [OR: 2.1, 95% CI (1.2-4.1), p value = 0.015]. Also subjects who carried the G allele of the ZNF259 polymorphism were at an increased the risk of developing CAD [OR 1.86, 95% CI: 1.06-3.25, p value = 0.029] and had an increased TC, LDL and TG levels (p < 0.05). Furthermore, no statistically significant association was found between genetic polymorphisms of PSRC1 A>G, LPL S447X and LPA C>T and CAD. We identified a relationship between a genetic variant in CETP and ZNF259 gene with CAD and CAD and lipid profile, respectively. Further investigation in a larger population may help to investigate the value of emerging marker as a risk stratification marker in CAD and its risk factors. Show less

Anacetrapib is an inhibitor of cholesteryl ester transfer protein (CETP), associated with reduction in LDL cholesterol and increase in HDL cholesterol in hypercholesterolemic patients. Anacetrapib was not taken forward into filing/registration as a new drug for coronary artery diease, despite the observation of a ∼9% reduction in cardiovascular risk in a large phase III cardiovascular outcomes trial (REVEAL). Anacetrapib displayed no adverse effects throughout extensive preclinical safety evaluation, and no major safety signals were observed in clinical trials studying anacetrapib, including REVEAL. However, anacetrapib demonstrated a long terminal half-life in all species, thought to be due, in part, to distribution into adipose tissue. We sought to understand the dependence of anacetrapib's long half-life on adipose tissue and to explore potential mechanisms that might contribute to the phenomenon. In mice, anacetrapib localized primarily to the lipid droplet of adipocytes in white adipose tissue; in vitro, anacetrapib entry into cultured human adipocytes depended on the presence of a mature adipocyte and lipid droplet but did not require active transport. In vivo, the entry of anacetrapib into adipose tissue did not require lipase activity, as the distribution of anacetrapib into adipose was-not affected by systemic lipase inhibition using poloaxamer-407, a systemic lipase inhibitor. The data from these studies support the notion that the entry of anacetrapib into adipose tissue/lipid droplets does not require active transport, nor does it require mobilization or entry of fat into adipose via lipolysis.

Transcriptome-wide association studies (TWAS) have recently gained great attention due to their ability to prioritize complex trait-associated genes and promote potential therapeutics development for complex human diseases. TWAS integrates genotypic data with expression quantitative trait loci (eQTLs) to predict genetically regulated gene expression components and associates predictions with a trait of interest. As such, TWAS can prioritize genes whose differential expressions contribute to the trait of interest and provide mechanistic explanation of complex trait(s). Tissue-specific eQTL information grants TWAS the ability to perform association analysis on tissues whose gene expression profiles are otherwise hard to obtain, such as liver and heart. However, as eQTLs are tissue context-dependent, whether and how the tissue-specificity of eQTLs influences TWAS gene prioritization has not been fully investigated. In this study, we addressed this question by adopting two distinct TWAS methods, PrediXcan and UTMOST, which assume single tissue and integrative tissue effects of eQTLs, respectively. Thirty-eight baseline laboratory traits in 4,360 antiretroviral treatment-naïve individuals from the AIDS Clinical Trials Group (ACTG) studies comprised the input dataset for TWAS. We performed TWAS in a tissue-specific manner and obtained a total of 430 significant gene-trait associations (q-value < 0.05) across multiple tissues. Single tissue-based analysis by PrediXcan contributed 116 of the 430 associations including 64 unique gene-trait pairs in 28 tissues. Integrative tissue-based analysis by UTMOST found the other 314 significant associations that include 50 unique gene-trait pairs across all 44 tissues. Both analyses were able to replicate some associations identified in past variant-based genome-wide association studies (GWAS), such as high-density lipoprotein (HDL) and CETP (PrediXcan, q-value = 3.2e-16). Both analyses also identified novel associations. Moreover, single tissue-based and integrative tissuebased analysis shared 11 of 103 unique gene-trait pairs, for example, PSRC1-low-density lipoprotein (PrediXcan's lowest q-value = 8.5e-06; UTMOST's lowest q-value = 1.8e-05). This study suggests that single tissue-based analysis may have performed better at discovering gene-trait associations when combining results from all tissues. Integrative tissue-based analysis was better at prioritizing genes in multiple tissues and in trait-related tissue. Additional exploration is needed to confirm this conclusion. Finally, although single tissue-based and integrative tissue-based analysis shared significant novel discoveries, tissue context-dependency of eQTLs impacted TWAS gene prioritization. This study provides preliminary data to support continued work on tissue contextdependency of eQTL studies and TWAS. Show less

The effects of increasing high-density lipoprotein cholesterol on cardiovascular outcomes remain uncertain. We conducted a meta-analysis to investigate the effects of high-density lipoprotein cholesterol modifiers (niacin, fibrates and cholesteryl ester transfer protein inhibitors) on cardiovascular outcomes. Thirty-one randomized controlled trials (154,601 patients) with a follow-up of 6 months or more and a sample size of 100 or more patients were selected using MEDLINE, EMBASE and CENTRAL database (inception January 2018). High-density lipoprotein cholesterol modifiers had no statistically significant effect on cardiovascular mortality in terms of relative risk (RR) (RR 0.94, 95% confidence interval (CI) 0.89-1.00, P = 0.05, I The use of high-density lipoprotein cholesterol modifying treatments had no significant effect on cardiovascular mortality, stroke or all-cause mortality.

The anaerobic feed of tannery effluent was treated using a new invention of an integrated approach: electrochemical oxidation with aerobic pretreatment, which reduces the chemical oxygen demand (COD) and sulfur/sulfide gas formation. Bacterial consortium was used in the present study isolated from a common effluent treatment plant (CETP). Microbial community analysis of anaerobic feed of tannery effluent (AFTE) was done by next generation sequencing. Under aerobic treatment, 79% and 85% of COD reduction were achieved during 3rd and 5th days of the aerobic process. The electrochemical oxidation process was applied for 60 min to reduce the remaining COD using the current density of 20 mA/cm Show less

The leather industry is a major source of environmental pollution in India. The wastewater generated by leather industries contains very high pollution parameters due to the presence of a complex mixture of organic and inorganic pollutants even after the treatment at a Common Effluent Treatment Plant (CETP) and disturbs the ecological flora and fauna. The nature, characteristics and toxicity of CETP treated wastewater is yet to be fully elucidated. Thus, this study aims to characterize and evaluate the toxicity of CETP treated tannery wastewater collected from the Unnao district of Uttar Pradesh, India. In addition to measuring the physico-chemical parameters, the residual organic pollutants was identified by GC-MS analysis and phytotoxicity, cytotoxicity and genotoxicity of the treated wastewater was evaluated using Vigna radiata L. and Allium cepa L. Results showed that the treated wastewater contained very high pollution parameters (TDS 3850 mg/L, BOD 680 mg/L, COD-1300 mg/L). GC-MS analysis revealed the presence of various types of residual organic pollutants including benzoic acid, 3-[4 Show less

A positive energy balance is considered to be the primary cause of the development of obesity-related diseases. Treatment often consists of a combination of reducing energy intake and increasing energy expenditure. Here we use an existing computational modelling framework describing the long-term development of Metabolic Syndrome (MetS) in APOE3L.CETP mice fed a high-fat diet containing cholesterol with a human-like metabolic system. This model was used to analyze energy expenditure and energy balance in a large set of individual model realizations. We developed and applied a strategy to select specific individual models for a detailed analysis of heterogeneity in energy metabolism. Models were stratified based on energy expenditure. A substantial surplus of energy was found to be present during MetS development, which explains the weight gain during MetS development. In the majority of the models, energy was mainly expended in the peripheral tissues, but also distinctly different subgroups were identified. In silico perturbation of the system to induce increased peripheral energy expenditure implied changes in lipid metabolism, but not in carbohydrate metabolism. In silico analysis provided predictions for which individual models increase of peripheral energy expenditure would be an effective treatment. The computational analysis confirmed that the energy imbalance plays an important role in the development of obesity. Furthermore, the model is capable to predict whether an increase in peripheral energy expenditure - for instance by cold exposure to activate brown adipose tissue (BAT) - could resolve MetS symptoms.

To evaluate cardiovascular (CV) outcomes in outpatients with coronary artery disease (CAD) living alone compared with those living with others. The prospeCtive observational LongitudinAl RegIstry oF patients with stable coronarY artery disease (CLARIFY) included outpatients with stable CAD. CLARIFY enrolled participants in 45 countries from November 2009 to July 2010, with 5 years of follow-up. Living arrangement was documented at baseline. The primary outcome was a composite of major adverse cardiovascular events (MACEs) defined as CV death, myocardial infarction (MI) and stroke. Among 32 367 patients, 3648 patients were living alone (11.3%). After multivariate adjustment, there were no residual differences in MACE among patients living alone compared with those living with others (HR 1.04, 95% CI 0.92 to 1.18, p=0.52); however, there was significant heterogeneity in the exposure effect by sex (P Living alone was not associated with an independent increase in MACE, although significant sex-based differences were apparent. Men living alone may have a worse prognosis from CV disease than women; further analyses are needed to elucidate the mechanisms underlying this difference. ISRCTN43070564. Show less

However, some negative effects increased (abdominal fat (AF) deposition, low feed conversion, etc.) have also been reported. In this study, the gene expression profiles of AF tissue in ovariectomized and sham-operated chickens were determined to identify differentially expressed genes (DEGs) and pathways to explore the molecular mechanisms underlying AF accumulation. Comparing the ovariectomized group and the sham-operated group, the abdominal fat weight (AFW) and abdominal fat percentage (AFP) were increased significantly ( Show less
