1. 16. Pro- and anticoagulant activities of factor V

   Författare :Elisabeth Thorelli; Malmö Klinisk kemi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; activated protein C; protein S; factor VIII; factor V; procoagulant; anticoagulant; Haematology; extracellular fluids; Hematologi; extracellulära vätskor;

   Sammanfattning : Coagulation factor V (FV) is activated by thrombin through proteolytic cleavage at Arg-709, Arg-1018 and Arg-1545. Upon thrombin activation, the active form of factor V (FVa) is formed. FVa functions as a cofactor to factor Xa in the conversion of prothrombin to thrombin during coagulation. LÄS MER

3. 17. Inflammation and Coagulation Activity in Unstable Coronary Artery Disease and the Influences of Thrombin Inhibition

   Författare :Jonas Oldgren; Steen Husted; Uppsala universitet; []
   Nyckelord :Medical sciences; Unstable coronary artery disease; inflammation; coagulation; thrombin inhibition; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; kardiologi; Cardiology;

   Sammanfattning : In patients with unstable coronary artery disease, this study evaluated the degree of inflammation and coagulation activity, relations to myocardial cell damage, prognosis, and influences of randomisation to 72 h infusion with three different doses of inogatran, a direct thrombin inhibitor (n=904), or unfractionated heparin (n=305). Anticoagulant treatment effects were evaluated with aPT time. LÄS MER

4. 18. Familial thrombophilia : Resistance to activated protein C and protein S deficiency

   Författare :Bengt Zöller; Malmö Klinisk kemi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Inherited resistance to activated protein C (APC-resistance) and protein S deficiency are associated with functional impairment of the protein C anticoagulant system, resulting in lifelong hypercoagulability andincreased risk of thrombosis. APC-resistance is the most common genetic cause of thrombosis being present in 20% to 60% of thrombosis patients. LÄS MER

5. 19. Thrombin generation in different cohorts : Evaluation of the haemostatic potential

   Författare :Roza Chaireti; Tomas Lindahl; Elvar Theodorsson; Sven Almer; Per Morten Sandset; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The aim of this thesis is to evaluate thrombin generation in patients with thrombophilia (Paper I), in patients with venous thromboembolism (Paper II), in healthy women during the menstrual cycle (Paper III), in patients with liver disease (Paper IV) and in patients with mild deficiency of factor VII (Paper V).For this purpose, thrombin generation was measured in platelet poor plasma by the calibrated automated thrombogram (CAT®) assay.

7. 20. Early assessment of efficacy and safety of novel anticoagulants as exemplified by direct thrombin inhibitors. Non-clinical pharmacodynamic studies in vitro and in vivo

   Författare :Margareta Elg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; animals; antidote; bleeding; inhibition constant; inogatran; association rate constant; melagatran; thrombin inhibitor; thrombosis; fibrinolysis;

   Sammanfattning : The drawbacks of today's anticoagulants are parenteral use (heparins), a narrow interval between efficacy and bleeding, and the high variability of effect with a consequent need for frequent monitoring (coumarins). The aim of the current studies was to evaluate properties important for efficacy and safety of novel anticoagulants, as exemplified by direct thrombin inhibitors, with non-clinical methods. LÄS MER
