Aims: Hyperlipidaemia enhances susceptibility to thrombosis, while platelet oxidixed LDL (oxLDL) binding in acute coronary syndrome (ACS) correlates with activation status. This study explores the platelet lipidome in symptomatic coronary artery disease (CAD) patients and the functional consequences of the chemokine CXCL12 and its receptors CXCR-4/-7 on lipid uptake in platelets. Methods and results: Platelet-oxLDL detected by flow cytometry was enhanced (P = 0...

Hyperlipidaemia and hypercholesterolaemia are risk factors of atherosclerosis and cardiovascular disease. The reference range of lipids during pregnancy has not yet been clearly set. This study sought to measure lipid parameters and pentraxin (PTX) 3 levels in low-risk pregnant women. The participants had serial blood samples taken between their 6th-9th week, 10th-13th week, 14th-19th week, 24th-29th week and 35th-40th week (as long as there were no contractions), during the labour period, and 2 days after delivery...

BACKGROUND: Coronary heart disease (CHD) is an important complication of atherosclerosis. Biomarkers, which associate with CHD development, are potential to predict CHD risk. To determine whether genes showing altered expression in hyperlipidaemia (H) and coronary heart disease (CHD) patients compared with controls could be CHD risk biomarkers. METHODS: Control, H, and CHD groups represented atherosclerosis to CHD development. Gene profiling was investigated in peripheral blood mononuclear cells using DNA microarrays...

OBJECTIVE: Rheumatoid arthritis (RA) portends significant cardiovascular morbidity and mortality. We therefore determined how often rheumatologists screened for and managed cardiovascular risk factors in RA patients, and the barriers to doing so. METHODS: We examined 300 patient charts from 10 university-affiliated rheumatology practices, to ascertain if they had been screened, treated and/or referred over a 3-year period. We subsequently distributed a national survey to Canadian rheumatologists to elucidate challenges in performing optimal cardiovascular risk modification...

OBJECTIVE: Both non-alcoholic fatty liver disease (NAFLD) and the multitarget complexity of microRNA (miR) suppression have recently raised much interest, but the in vivo impact and context-dependence of hepatic miR-target interactions are incompletely understood. Assessing the relative in vivo contributions of specific targets to miR-mediated phenotypes is pivotal for investigating metabolic processes. DESIGN: We quantified fatty liver parameters and the levels of miR-132 and its targets in novel transgenic mice overexpressing miR-132, in liver tissues from patients with NAFLD, and in diverse mouse models of hepatic steatosis...

Gemfibrozil, a peroxisome proliferator-activated receptor α (PPARα) agonist, is widely used for hypertriglyceridaemia and mixed hyperlipidaemia. Drug-drug interaction of gemfibrozil and other PPARα agonists has been reported. However, the role of PPARα in Cytochrome P450 (CYP) induction by fibrates is not well known. In this study, wild-type mice were first fed gemfibrozil-containing diets (0.375%, 0.75% and 1.5%) for 14 days to establish a dose-response relationship for CYP induction. Then, wild-type mice and Pparα-null mice were treated with a 0...

Psoriasis is frequently associated with metabolic comorbidities. Advanced glycation end products (AGEs) are highly oxidant, biologically active compounds that accumulate in tissues in association with hyperglycaemia, hyperlipidaemia and oxidative stress. This is a cross-sectional case-control study involving 80 patients with mild/severe psoriasis and 80 controls matched for age, sex and body mass index (40 with severe eczema, 40 healthy individuals). Patients and healthy individuals with a smoking habit, diabetes, dyslipidaemia, hypercholesterolaemia, hypertension or who were under systemic treatment were excluded from the study...

BACKGROUND: The exact mechanism(s) of atherosclerosis in humans remains elusive, but one theory hypothesizes that this deleterious process results from the oxidative modification of low-density lipoprotein (LDL). Research suggests that foods rich in dietary phenolic compounds with antioxidant activity can mitigate the extent of LDL oxidation in vivo. With regard to the different classes of flavonoids, there appears to be a structure-function relationship between the various moieties/constituents attached to the flavonoids' three ring system and their impact at retarding LDL oxidation...

Background Familial hypercholesterolemia is a common autosomal dominant disease, caused by mutations leading to elevated low-density lipoprotein (LDL) cholesterol and, if untreated, to premature cardiovascular disease. Methods Patients (young adults with a family history of hypercholesterolaemia or premature cardiovascular disease) with LDL cholesterol concentration ≥4.9 mmol/l, after excluding Familial Combined Hyperlipidaemia, were evaluated for causative mutations, Dutch Lipid Clinic Network score calculation and non-invasive ultrasound examination of carotid arteries...

The aim of present investigation was the preparation of dodecylamine template-based hexagonal mesoporous silica (HMS) as a carrier for poorly water-soluble drug (fenofibrate). HMS material has distinctive characteristics such as easy synthesis, high surface area and wormhole pores. These characteristics are highly admirable to make use of it as a carrier in drug delivery system. HMS was prepared by pH and temperature-independent process. Fenofibrate was loaded into the HMS by solvent immersion method using organic solvent...

INTRODUCTION: Nocardia species usually cause opportunistic infections, and the frequency of these infections is increasing owing to the growing population of immunocompromised hosts. However, Nocardia species may sometimes cause an infection disease in immunocompetent hosts. Nocardia mexicana infections are the least common and are very rare. CASE PRESENTATION: Herein, we report the first case of a pulmonary infection with N. mexicana in a 61-year-old Japanese woman with a history of hyperlipidaemia and bronchiectasis and a 6-month history of non-productive hacking cough...

Obesity is a well-established risk factor for atherosclerosis. However, the mechanistic link between accumulation of adipose tissue and development of atherosclerosis is not clear. Adipose tissue comprises various depots including white adipose tissue (WAT), brown adipose tissue (BAT) and thoracic and abdominal perivascular adipose tissue (PVAT). The phenotype of thoracic PVAT resembles BAT, whereas abdominal PVAT is more like WAT. Here, we review the distinct roles of the adipose tissue depots in the development of atherosclerosis with the ultimate aim to understand how these can be targeted to reduce atherosclerosis...

BACKGROUND: A haemostatic technique that maintains radial artery flow ("patent haemostasis") following transradial catheterization reduces rates of radial artery occlusion (RAO) in patients with stable coronary disease. It is unclear whether this benefit extends to patients with an acute coronary syndrome (ACS). METHODS: Patients undergoing inpatient transradial catheterization for an ACS were prospectively enrolled in a consecutive cohort study (n=300). Radial haemostasis was obtained using standard radial compression (cohort 1; n=150) or patent haemostasis (cohort 2; n=150)...

While elevated blood cholesterol has been associated with an increased risk of colorectal cancer (CRC) in observational studies, causality is uncertain. Here we apply a Mendelian randomisation (MR) analysis to examine the potential causal relationship between lipid traits and CRC risk. We used single nucleotide polymorphisms (SNPs) associated with blood levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) as instrumental variables (IV). We calculated MR estimates for each risk factor with CRC using SNP-CRC associations from 9,254 cases and 18,386 controls...

Perivascular spaces that are visible on magnetic resonance imaging (MRI) are a neuroimaging marker of cerebral small vessel disease. Their location may relate to the type of underlying small vessel pathology: those in the white matter centrum semi-ovale have been associated with cerebral amyloid angiopathy, while those in the basal ganglia have been associated with deep perforating artery arteriolosclerosis. As cerebral amyloid angiopathy is an almost invariable pathological finding in Alzheimer's disease, we hypothesized that MRI-visible perivascular spaces in the centrum semi-ovale would be associated with a clinical diagnosis of Alzheimer's disease, whereas those in the basal ganglia would be associated with subcortical vascular cognitive impairment...

Objective Coronary artery dilations (CDs), a subgroup of coronary artery anomalies (CAAs), are relatively rare but important cardiac pathologies. They are considered to be linked to coronary atherosclerosis in most cases. Methods The demographic data, multi-slice computed tomographic coronary angiography data, coronary calcium score, and ascending aortic diameter (AAD) of 1538 patients were reviewed. In total, 197 (12.8%) patients (166 men, 31 women; age 15 - 84 years; mean 55.78 ± 12.32 years) with CAAs were identified, and 81 (5...

Monocytes are heterogeneous effector cells involved in the maintenance and restoration of tissue integrity. Monocytes and macrophages are involved in cardiovascular disease progression, and are associated with the development of unstable atherosclerotic plaques. Hyperlipidaemia can accelerate cardiovascular disease progression. However, monocyte responses to hyperlipidaemia are poorly understood. In the past decade, accumulating data describe the relationship between the dynamic blood lipid environment and the heterogeneous circulating monocyte pool, which might have profound consequences for cardiovascular disease...
