Experimental endocarditis induction and platelet aggregation byStreptococcus anginosus,Streptococcus constellatusandStreptococcus intermedius

Antibodies Targeting Hsa and PadA Prevent Platelet Aggregation and Protect Rats against Experimental Endocarditis Induced by Streptococcus gordonii.

Streptococcus gordonii and related species of oral viridans group streptococci (VGS) are common etiological agents of infective endocarditis (IE). We explored vaccination as a strategy to prevent VGS-IE, using a novel antigen-presenting system based on non-genetically modified Lactococcus lactis displaying vaccinogens on its surface. Hsa and PadA are surface-located S. gordonii proteins implica...

Platelet Phagocytosis and Aggregation

The addition of latex particles to native (no anticoagulant) or citrated human platelet-rich plasma (PRP), or to a once-washed platelet suspension causes platelet aggregation. This aggregation is associated with phagocytosis of the latex particles by the platelets and appears to be due to release of adenosine diphosphate (ADP) from the platelets. Adenosine and adenosine monophosphate, which are...

Platelet lipid composition and platelet aggregation

Abnormal plasma lipoproteins in patients with liver disease are associated with an increase in erythrocyte cholesterol concentration and a raised erythrocyte cholesteroVphosphoEpid molar ratio. We hypothesized that their platelets would also have an increased cholesteroVphospholipid ratio and that this might affect aggregation in vitro. Platelet aggregation by adrenaline and ADP was measured in...

Evaluation of anti-platelet aggregation effect of some Allium species

Epidemiologic studies show that the cardiovascular diseases are associated with multiple factors such as raised serum total cholesterol, increased LDL, increased platelet aggregation, hypertension and smoking. In-vitro studies have confirmed the ability of some plants of Allium species to reduce these parameters. Therefore, we evaluated anti-platelet aggregation effect of some Allium species (A...
