If a woman is a carrier there is a 1 in 2 chance that any son will be affected and a 1 in 2 chance that any daughter will be a carrier. If a man with the disease fathers a child, any daughter will be a carrier and any son will be unaffected and will not carry the gene. There is a report of a daughter of a man with the disease who had a factor IX level of 5% and haemarthroses and this was though...
Background: During extrinsic coagulation pathway, a complex is developed between factor VII, calcium and tissue factor (a cell membrane lipoprotein that is exposed after cell injury). Factor VII needs calcium and vitamin K for its biologic activation. Coronary artery disease can be induced by increased level and activity of the coagulation factors VII, VIII and IX. In postmenopausal period, est...
Human plasma–derived factor IX (pdFIX) concentrates are routinely used to treat patients with hemophilia B, an X-linked bleeding disorder that affects 1 in 30 000 males, but concerns remain regarding transmission of blood-borne pathogens. Therefore, the safety and efficacy of recombinant human factor IX (rFIX) were evaluated. A 20-center international trial was conducted in previously treated p...
An investigation of the behavior of protoporphyrin IX, deuteroporphyrin IX, haematoporphyrin IX and coproporphyrin III in aqueous solution revealed extensive and complex aggregation processes. Protoporphyrin appears to be highly aggregated under all conditions studied. At concentrations below 4 muM, aggregation of deutero-, haemato- and coproporphyrin is probably restricted to dimerization. At ...
Glass-contacted human serum infused into animals induces stasis thrombi similar to red thrombi observed in man (1). The activity in glass-contacted human serum initiating these thrombi has been termed serum thrombotic accelerator (STA) activity (2). It can be measured by a rabbit assay (3) and is distinct from tissue thromboplastin, platelets, and thrombin (4, 5). Silicone-processed ("intact") ...
OBJECTIVE The platelet glycoprotein Ib-IX (GP Ib-IX) receptor is a well-characterized adhesion receptor supporting hemostasis and thrombosis via interactions with von Willebrand factor. We examine the GP Ib-IX/von Willebrand factor axis in murine polymicrobial sepsis, as modeled by cecal ligation and puncture (CLP). APPROACH AND RESULTS Genetic absence of the GP Ib-IX ligand, von Willebrand f...
