Abstract
We hypothesize that the hemostatic potential (HP) of freshly thawed (FFP-0) was superior to plasma stored for 5 days (FFP-5).
FFP from 30 single donors were thawed at 37°C and kept at 1°C to 6°C for 5 days. HP was evaluated at day 0 and 5 by measuring kinetics of thrombin generation (TG), kinetic...

Abstract
We prospectively followed 343 patients after a first episode of objectively proven VTE. We excluded all patients with VTE at unusual sites, older than 70 years old, with neoplasia, liver or renal chronic disease and antiphospholipid syndrome. Predictors for recurrence were evaluated by Cox model. Th...

Abstract
We studied 46 hemostatic parameters in 566 participants: 280 patients with mucocutaneous bleeding and 286 controls. The F12 -4T allele, associated with reduced levels of FXII (P < 0.001), also significantly delayed the activated partial thromboplastin time (aPTT) expressed as aPTTr (ratio sample pla...

Abstract
We hypothesize that soluble clotting factors released during a mechanical thrombectomy procedure may be responsible for creating a localized hypercoagulable state and could be one of the underlying causes of recurrent thrombosis.
Blood samples were obtained from 20 participants with no history of hy...

Abstract
SUMMARY: Despite major advances in diagnosis and treatment, the management of patients with mild haemophilia (MH) remains a major challenge. Mild haemophilia is defined by factor levels between 0.05 and 0.40 IU mL(-1). The bleeding associated with mild haemophilia is most frequently episodic, occurr...

Abstract
SUMMARY: The rationale for long-term prophylaxis in more severe forms of von Willebrand's disease (VWD) is obvious, as mucosal bleeding and haemophilia-like joint bleeds resulting in chronic morbidity may occur. However, the experience with prophylactic treatment in this group is scanty. An internat...

Abstract
We show that the adenoviral-associated humoral and innate cytokine immune responses are significantly reduced when HAdV-5 vector carrying human bovine chimeric fibers (HAdV-5-F2/BAdV-4) is intravenously injected into mice. Fiber pseudotyping modified its interaction with blood coagulation factors, a...

We investigated the exact location of these two cleavages, by substitution of arginines by glutamine within the R(x1)-region (R501, R505 or R510) and the R(x2)-region (R313, R316, R317 or R321). Immunoblot and kinetic analyses of the inactivation of activated R(x1)-mutants by APC revealed that using...

Pregnant women required a mean UFH dose of 236.9 units/kg/day to achieve the targeted antifactor Xa level of 0.1-0.3 unit/ml. The required UFH doses correlated with patient weight, and most antifactor Xa levels were within the desired target range. These findings may assist clinicians in more precis...
