04/2006 | Thrombosis and Haemostasis, SchattauerMany coagulation parameters, such as PT or aPTT, show agedependency. In this study we investigated if the generation of thrombin, possibly better reflecting overall haemostasis, shows an age-dependency...

05/2006 | Thrombosis and Haemostasis, SchattauerBy the use of a fluorogenic thrombin substrate and continuous calibration of each individual sample, it is now possible to obtain a thrombin generation (TG) curve (or thrombogram) in plasma, with or without platelets, in an easy routine procedure at high throughput and with an acceptable experimental error (<5%)...

11/2006 | Thrombosis and Haemostasis, SchattauerThere is currently no validated method to detect a prothrombotic phenotype. The question remains, can tissue factor (TF) induced thrombin generation (TG), as measured with the calibrated automated thrombinography (CAT) technique, according to Hemker et al., recognise a prothrombotic state either as such, or when the activated protein C (APC)-system is boosted with thrombomodulin (TM)? We determined the normal range of CAT-TG TM in a group of 71 healthy blood donors, in 11 healthy women using oral contraceptives (OC), and in 89 patients with a history of venous thromboembolism (VTE), divided into a group of 50 in which a prothrombotic risk factor could be found (VTEprf+) and 39 others (VTEprf-)...

11/2006 | Thrombosis and Haemostasis, SchattauerPlatelet microparticles (PMPs) are small vesicles released from blood platelets upon activation. The procoagulant activity of PMPs has been previously mainly characterized by their ability to bind coagulation factors VIII and Va in reconstructed systems...

03/2007 | Thrombosis and Haemostasis, SchattauerLipopolysaccharide (LPS)-stimulated monocytes are known to have a procoagulant effect. This property is currently explained by the fact that monocytes, in response to LPS, can express tissue factor (TF) and undergo a process of membrane microvesiculation...
