Mice with hemophilia B have been engineered using gene targeting techniques. These animals exhibit severe factor IX deficiency and a clinical phenotype that mirrors the human disease. We have bred the founder animals onto two different strains of mice, C57B1/6 and CD-1, and have sought to determine whether adenoviral vectors expressing human factor IX could correct the bleeding diathesis of mic...

: Risk for thrombotic events with factor IX replacement therapy in patients with haemophilia B remains a concern for patients, those who treat them, and regulatory agencies, based on experience with early use of prothrombin complex concentrates. The current post hoc analysis assessed the incidence of thrombotic events and changes in prothrombin fragment 1 + 2, thrombin-antithrombin complex, and...

This review focuses on selected areas that should interest both the scientist and the clinician alike: polymorphisms within the factor VIII and factor IX genes, their linkage, and their ethnic variation; a general assessment of mutations within both genes and a detailed inspection of the molecular pathology of certain mutations to illustrate the diverse cause-effect relations that exist; a summ...

Human factor VIII from normals and hemophiliacs was partially purified by ethanol and polyethylene glycol precipitations. Final purification was achieved by gel filtration on 2 or 4% agarose or ion exchange chromatography on diethylaminoethyl cellulose. Comparable amounts of highly purified protein were obtained from normal and hemophilic plasma following the agarose chromatography step. Highly...

With the increasing availability and affordability of safe factor concentrate replacement therapy, factor prophylaxis, and comprehensive care, persons with hemophilia (PWH) today should have a normal life expectancy, and more are living beyond age 65 years. However, comorbid complications associated with aging in this population are largely unknown, and background data on the clinical implicati...

background and aims. hemophilic patients are faced with poor oral hygiene due to concerns about their dental care. the present study assessed the knowledge of hemophilic patients about oral hygiene and the effect of oral hygiene instruction in patients referred to iranian hemophilia society. materials and methods. this cross-sectional study was carried out on 30 hemophilic patients randomly sel...
