Role of platelets in regulating activated coagulation factor XI activity. Activated factor XI increases the procoagulant activity of the extrinsic pathway by inactivating tissue factor pathway inhibitor. Model for a factor IX activation complex on blood platelets: dimeric confor...

Cellulofine, we have isolated a novel blood coagulation factor X-binding protein with anticoagulant activity from the venom of Trimeresurus ...
The prolongation of both conditions was not corrected by a mixing test and factor V activity was reported to be 2%. Quantified titers of inhibitors were increased from 3.5 Bethesda unit to 8.4 Bethesda unit during follow-up analysis. In spite of the treatment with steroids and intravenous ...

Conservative mutations in the C2 domains of factor VIII and factor V alter phospholipid binding and cofactor activity. Blood 120, 1923–1932 (2012). 31. Jacquemin, M. et al. A novel cause of mild/moderate hemophilia A: mutations scattered in the factor VIII C1 domain reduce factor VIII ...
Hemophilia B can be detected prenatally by measuring FIX activity in fetal blood samples obtained at 20 weeks of gestation by fetoscopy, but the presence of maternal FIX in amniotic fluid complicates the assessment. In addition, the procedure carries a high risk of complications, with a risk of...
