Hemophilia A is a bleeding disorder caused by defective production of factor VIII. The main concern associated with the disease is bleeding, especially after trauma and surgeries. Factor VIII replacement therapy is associated with substantial decrease of bleeding events during surgery. However, there have been a number of reports of thromboemblic events in this situ-ation. The present report de...

Factor VIII is tightly noncovalently linked to von Willebrand factor (vWF) in plasma with a stoichiometry of 1:50, and vWF deficiency results in secondary factor VIII deficiency, with accelerated clearance of factor VIII from the circulation. We used a murine model of severe von Willebrand disease (vWF knockout mice) to study the effect of a recombinant vWF/pro-vWF preparation (rpvWF) on factor...

We recently described tolerance induction with factor VIII/IX, cyclophosphamide, and high-dose intravenous IgG in hemophilia A or B patients with coagulation inhibitory antibodies. Circulating noninhibitory antibodies complexed with factor IX have been demonstrated in tolerant hemophilia B patients. Similar findings are now described in six tolerant hemophilia A patients. Complexes between fact...

By macroscopic and microscopic dorsal side observation, it was noted that the IX and X segments of two species each of Panstrongylus and Triatoma terminate in an elongated way, whereas they terminate abruptly in the two species of Rhodnius. Scanning observation of the dorsal, ventral, lateral and posterior sides of the female genitalia of Panstrongylus herreri, Panstrongylus megistus, Rhodnius ...

The Os(VIII) oxo/hydroxido complexes that are abundant in mild to relatively concentrated basic aqueous solutions are Os(VIII)O4, [Os(VIII)O4(OH)](-) and two cis-[Os(VIII)O4(OH)2](2-) species. Os(VIII) complexes that contain water ligands are thermodynamically unfavoured w.r.t. the abovementioned species. Os(VIII)O4 reacts with hydroxide in two, consecutive, elementary coordination sphere expan...

The binding of factor VIII to von Willebrand factor (vWF) is essential for the protection of factor VIII against proteolytic degradation in plasma. We have characterized the binding kinetics of human factor VIII with vWF using a centrifugation binding assay. Purified or plasma vWF was immobilized with a monoclonal antibody (MoAb RU1) covalently linked to Sepharose (Pharmacia LKB Biotechnology, ...

Objective(s): The purpose of the present study was the immunohistochemical evaluation of VEGF and VII factors in dog’s teeth pulp revascularized with MTA and propolis. Materials and Methods: 144 mature and immature two rooted dog’s premolar canals were selected.  Pulp necrosis and infection were established after 2 weeks and the disinfection of the canals was done with copious NaOCl irrigation ...

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...
