Type 2 diabetes is characterized by increased plasma triglyceride levels and a fourfold increase in ischemic heart disease, but the mechanism is unclear. CD36 is a receptor/transporter that binds fatty acids of lipoproteins. CD36 deficiency has been linked with insulin resistance. There is strong evidence of in vivo interaction between platelets and atherogenic lipoproteins suggesting that athe...

Ardisia elliptica Thunberg (Myrsinaceae) is a medicinal plant traditionally used for alleviating chest pains, treatment of fever, diarrhoea, liver poisoning and parturition complications. The objectives of the study were to investigate the effect of A. elliptica on collagen induced platelet aggregation and to isolate and purify potential antiplatelet components. Fresh A. elliptica leaves were e...

BACKGROUND Platelet aggregation mediated by inflammation played a critical role in the development of coronary heart diseases (CHD). Our previous clinical researches showed that Th17 cells and their characteristic cytokine IL-17A were associated with the plaque destabilization in patients with acute coronary syndrome (ACS). However, the potent effect of IL-17A on platelets-induced atherothrombo...

preparations of platelet concentrates (pcs) that are stored under blood bank conditions and used for transfusion purposes, appear to be enriched in platelet derived-microparticles (pmps) with high coagulant activity that may change platelet efficacy and safety issues. high shear stress could cause shedding of pmps from the platelet plasma membrane, platelet aggregation, and activation of the co...

AIMS High plasma cholesterol concentration and increased platelet activity are two major risk factors for atherosclerosis. Lovastatin, the lipophilic drug was shown to inhibit platelet aggregation whereas pravastatin, the hydrophilic drug had no such effect. Analysis of the effect of fluvastatin which is both a lipophilic and hydrophilic drug, on platelet aggregation was the goal of the present...

One hundred and seven patients with congestive heart failure, myocardial infarction and arteriosclerotic heart disease were studied by adenosine diphosphate-induced platelet aggregation, fibrinogen levels and ethanol gelation test. Both increases and decreases in platelet aggregation were observed. A significantly high percentage of patients showed a decreased platelet aggregation which was esp...

BACKGROUND After activation, platelets adhere to neutrophils via P-selectin and beta2-integrin. The molecular mechanisms and adhesion events in whole blood exposed to venous levels of hydrodynamic shear in the absence of exogenous activation remain unknown. METHODS AND RESULTS Whole blood was sheared at approximately 100 s(-1). The kinetics of neutrophil-platelet adhesion and neutrophil aggre...

Platelet adhesion to the subendothelial matrix and the subsequent aggregation of the activated platelets is a special case of intercellular adhesion that is highly regulated and for which multiple, possibly redundant adhesive systems exist. The large "adhesive glycoproteins" such as fibrinogen, von Willebrand factor, and fibronectin and their receptors, which participate in platelet adhesion an...

Parthenolide (Ptn), a member of sesquiterpene lactones, isolated from a herb — feverfew (Thanaceum parthenium), has been recently examined as anti-cancer and anti-inflammatory agent. It was also studied in prophylaxis and treatment of the migraine in humans. Some incidental reports suggested also its anti-platelet activity. In this study, we investigated the effect of Ptn and the synthesized 1-...

This study investigated the effects of isotenuifolide and tenuifolide B from the stems of Cinnamomum tenuifolium on adenosine diphosphate (ADP)-induced human platelet aggregation. Treatment of human platelet-rich plasma with isotenuifolide (1 and 2 μg/μL) and tenuifolide B (1, 2 and 4 μg/μL) did not have any significant effect on human platelet aggregation in vitro, however, treatment of human ...
