Abstract Aims High-density lipoproteins (HDLs) are circulating micelles that transport proteins, lipids, and miRNAs. HDL-transported miRNAs (HDL-miRNAs) have lately received attention but their effects on vascular cells are not fully understood. Additionally, whether cardiovascular risk factors affect HDL-miRNAs levels and miRNA transfer to recipient cells remains equally poorly known. Here, we have investigated the changes induced by hypercholesterolaemia on HDL-miRNA levels and its effect on recipient endothelial cells (ECs). Methods and results Pigs were kept on a high-fat diet (HC; n = 10) or a normocholesterolaemic chow (NC; n = 10) for 10 days reaching cholesterol levels of 321.0 (229.7–378.5) mg/dL and 74.0 (62.5–80.2) mg/dL, respectively. HDL particles were isolated, purified, and quantified. HDL-miRNA profiling (n = 149 miRNAs) of HC- and NC-HDLs was performed by multipanel qPCR. Cell cultures of porcine aortic ECs were used to determine whether HDL-miRNAs were delivered to ECs. Potential target genes modulated by miRNAs were identified by bioinformatics and candidate miRNAs were validated by molecular analysis. In vivo effects in the coronary arteries of normocholesterolaemic swine administered HC- or NC-HDLs were analysed. Among the HDL-miRNAs, four were found in different amounts in HC- and NC-HDL (P < 0.05). miR-126-5p and -3p and miR-30b-5p (2.7×, 1.7×, and 1.3×, respectively) were found in higher levels and miR-103a-3p and miR-let-7g-5p (−1.6×, −1.4×, respectively) in lower levels in HC-HDL. miR-126-5p and -3p were transferred from HC-HDL to EC (2.5×; P < 0.05), but not from NC-HDL, by a SRB1-mediated mechanism. Bioinformatics revealed that HIF1α was the miR-126 target gene with the highest predictive value, which was accordingly found to be markedly reduced in HC-HDL-treated ECs and in miR126 mimic transfected ECs. In vivo validation confirmed that HIF1α was diminished in the coronary endothelial layer of NC pigs administered HC-HDL vs. those administered NC-HDL (P < 0.05). Conclusion Hypercholesterolaemia induces changes in the miRNA content of HDL enhancing miR126 and its delivery to ECs with the consequent down-regulation of its target gene HIF1α.

Pen Shells (A. pectinata) Is one type of a clam that is mostly consumed, Cholesterol levels included in a category high. Although the high cholesterol levels. Shells also contain levels commonly called ldl cholesterol evil . Having shells also levels of hdl, Cholesterol levels total normal in plasma adults is of 120 until 200 mg/dl. Different from its function at the time of cholesterol levels normal, the higher cholesterol levels in the blood, the greater the risk of atherosclerosis also. The purpose of this research is to get information about ldl levels , hdl and cholesterol contained in shells kampak , as well as to determine the shells kampak who most worthy for consumption. Parameter that observed in this research was ldl , hdl , cholesterol .This study using methods descriptive against the difference levels of low density lipopprotein ( ldl ) and high-density lipoproteins ( hdl ) and cholesterol in any bivalve hatchets the results of catch fishermen in kenjeran surabaya.

AbstractBackgroundFew studies have assessed the performance of stroke prevention clinics. In particular, limited information exists on patient compliance, achievement of therapeutic targets, and related occurrence of vascular events.MethodsWe compared our clinical practice to recommendations from published guidelines in newly referred patients for transient ischemic attack (TIA) or ischemic stroke between 2008 and 2010. We monitored our cohort for at least 1 year and assessed for adequacy of vascular risk factor management, drug adherence, and occurrence of nonlethal vascular outcomes.ResultsOf 408 patients, 57.8% had a stroke and 42.2% a TIA. The mean age was 68±13 years, and 52% male. Average follow-up was 15.8 months. During follow-up, 253 patients (70.3%) completely achieved their blood pressure target, 151 (45.5%) achieved their low-density lipoprotein (LDL) cholesterol target, and 407 (99.8%) were on antithrombotics. Eighty-nine patients (21.8%) attained optimal therapy status, defined as reaching targets for LDL cholesterol, blood pressure, and antithrombotic use. Adherence to drug therapy was associated with attainment of optimal therapy status (p=0.01). Diabetes was associated with lower probability of attaining optimal therapy status (odds ratio [OR], 0.36; 95% confidence interval [CI], 0.20-0.66) and blood pressure targets (OR, 0.09; 95% CI, 0.05-0.17). During follow-up, 52 (12.7%) patients had a nonlethal vascular event.ConclusionOur study shows good attainment of therapeutic goals associated with adherence to drug therapy. However, optimal therapy status and blood pressure targets were more difficult to attain in patients with diabetes; therefore, more intensive preventive efforts may be required for these individuals.

Introduction: Epidemiological studies suggest a link between plasma high-density lipoprotein (HDL) cholesterol levels and Alzheimer’s disease (AD) risk through mechanisms that are not understood. We hypothesize that HDL protects against AD through actions at the blood-brain-barrier. HDL has vasoprotective functions in large peripheral arteries, however, it is unknown if these functions extend to cerebral vessels to reduce the contribution of cerebrovascular dysfunction in AD pathogenesis. We investigated in vitro interactions between HDL and amyloid beta (Aβ), the toxic peptide known to accumulate in AD, in peripheral and brain-derived endothelial cells (EC). Methods: HDL was isolated by density gradient ultracentrifugation and added to human umbilical vein endothelial cells (HUVEC) or human cerebral microvascular endothelial cells (hCMEC/D3). Cell activation was measured by counting adhered labelled peripheral blood mononuclear cells (PBMC) after stimulation with tumour necrosis factor α (TNFα) or Aβ. Aβ binding and uptake into cells was measured using ELISA and immunofluorescence. All experiments included at least 4 independent replicates. Results: We demonstrate that HDL attenuates Aβ-induced EC activation independent of nitric oxide production, miR-233 and changes in adhesion molecule expression. Rather, HDL acts through scavenger receptor BI to block Aβ uptake into ECs and, in vitro , can maintain Aβ in a soluble state. We validated our results using three dimensional engineered vessels composed of primary human endothelial and smooth muscle cells. Following Aβ addition to the abluminal (brain) side, we demonstrated that HDL circulated within the lumen attenuates EC activation, again independent of intracellular adhesion molecule changes. Conclusions: We show that the anti-inflammatory activities of HDL extend to cerebrovascular endothelial cells and work to suppress Aβ-induced activation through a novel mechanism involving the inhibition of Aβ binding and uptake into cells through SR-BI. The protective role for HDL against Aβ may explain the epidemiological evidence supporting a protective effect of high plasma HDL cholesterol levels against dementia.

Medical approaches to reducing the risk of recurrent stroke following ischaemic stroke or transient ischaemic attack, and other major vascular events, involves a targeted modification of vascular risk factors, including lifestyle factors (e.g. physical inactivity, smoking, and diet), hypertension, and hyperlipidaemia and glycaemic control. The INTERSTROKE study reported that ten potentially modifiable vascular risk factors were associated with about 90% of the population attributable risk for stroke. Modification of lifestyle risk factors remains a cornerstone of stroke prevention, and includes promoting increased physical activity, smoking cessation, adopting healthier dietary patterns, weight reduction in those who are overweight/obese, and avoiding high alcohol intake (and heavy episode alcohol intake). All patients with blood pressure levels greater than or equal to 140/90 mmHg should be treated with antihypertensive therapy (although some suggest a lower threshold in patients with non-cardioembolic stroke), with a recent trial suggesting that patients with small vessel ischaemic stroke may benefit from lowering blood pressure to less than 130/90 mmHg. Statin therapy in patients with elevated low-density lipoprotein is associated with a reduction in major vascular events after ischaemic stroke, with a more aggressive strategy adopted in patients with ischaemic stroke due to large vessel atherosclerosis. While sleep apnoea is a risk factor for stroke, treatment with continuous positive airway pressure did not reduce the risk of stroke in a recent, large clinical trial. The optimal approach to achieve high rates of vascular risk factor targets following stroke has not been identified, but evaluations of community-based interventions are ongoing.
