Abstract (26)

A step forward in the evaluation of platelet function testing: routine, simultaneous measurement of platelet aggregation, serotonin (5-HT) content and secretion by HPLC-electrochemical detection in hemostasis laboratories
GPIb alpha activation mediates platelet tissue factor (TF) phosphorylation, transfer to lipid rafts (LR) and activity. TFPI and protein S, released by other agonists, would assemble the inhibitory complex (TF/FVIIA/TFPI/PS) in LR, dampening FXA activity
Hemostatic disorder of uremia: patients with terminal chronic renal failure (CRF) have increased platelet tissue factor derived intravascular clotting activation with delayed clot lysis time in platelet rich plasma (CLT-PRP)
Revisiting the hemostatic disorder of uremia: patients on peritoneal dialysis (CRF-PD) have normal platelet aggregation and secretion but increased platelet tissue factor activity (TF-PCA), probably the cause of intravascular clotting activation
