Background. The heparin protocols used during cardiopulmonary bypass (CPB) in children undergoing surgical repair for congenital heart disease are extrapolated from adult data. Studies are needed that assess the optimal heparin dosing in these children, whose heparin clearance is increased compared with that in adults. Methods. We assessed the effe...

Thrombin contributes to the pathogenesis of acute myocardial infarction and reocclusion after thrombolysis. Thrombolytic therapy is known to induce a paradoxic increase in thrombin generation. Specific thrombin inhibition enhances thrombolytic therapy in experimental models. The aim of this study was to determine thrombin generation in patients wit...

The laboratory assessment of platelet biology and coagulation has traditionally focused on abnormalities, congenital or acquired, that provide insights for understanding hemostatic defects, unexplained bleeding, and pharmacologic titration of compounds designed to attenuate thrombotic potential. Because atherosclerotic vascular disease is associate...

The diagnosis of the antiphospholipid syndrome (APS) requires both a typical clinical event plus a persistently positive test in an assay for either anticardiolipin (aCL) antibodies or a lupus anticoagulant (LA). Enzyme linked immunosorbent assays (ELISA) specific for autoantibodies against beta(2)-glycoprotein I (beta(2)GPI) or prothrombin are als...

The process of tissue factor initiated blood coagulation is discussed. Reactions of the blood coagulation cascade are propagated by complex enzymes containing a vitamin K-dependent serine protease and an accessory cofactor protein that are assembled on a membrane surface in a calcium-dependent manner.These complexes are 105 109-fold more efficient ...

Diamond-like carbon (DLC) and silicon carbide (SiC) coat- ings are attractive because of low friction coefficient, high hardness, chemical inertness and smooth finish, which they provide to biomedical devices. Silicon wafers (Si and silicone rubber (Si) plates were coated using plasma- enhanced chemical vapour deposition (PE-CVD) tech- niques. This...

This article reviews work performed at the Medical College of Virginia of Virginia Commonwealth University during the development of a whole-blood assay of platelet function. The new assay is capable of assessing platelet function during clotting and thus allows measurement of the contribution of platelets to thrombin generation. Because platelets ...

BackgroundIt is well described that diabetes mellitus is a hypercoagulable state. It is also known that patients with renal dysfunction have impaired platelet aggregation and function. It is not well described how renal dysfunction affects the hypercoagulability associated with diabetes. This post-hoc sub-group analysis compares platelet function, ...

Reliable markers and methods to predict risk for thrombosis are essential to clinical management. Using an integrated approach that defines an individual's comprehensive coagulation phenotype might prove valuable in identifying individuals at risk for experiencing a thrombotic event. Using a numerical simulation model, we generated tissue factor (T...

Recombinant human-activated protein C (rhAPC, Drotrecogin alpha (activated), Xigris) has been shown to reduce organ damage and decrease mortality in severe sepsis. Since protein S (PS) serves as a potentiating cofactor of activated protein C and since PS levels are low in neonatal plasma, we hypothesized that the anticoagulant effect of rhAPC would...
