The treatment of hemophilia A patients with inhibitor could be very expensive. Ankaferd blood stopper (ABS) is a unique folkloric medicinal plant extract, which has historically been used in Turkish traditional medicine as a hemostatic agent. In this article, a 16-year-old boy was presented with uncontrolled bleeding, despite the treatment of factor VIII, rVIIa, factor VIII inhibitor bypass act...

venom with serum and platelets resulted in a progressive increase in coagulant activity. Peden & Peacock (1958) found that ox serum was particularly active in potentiating the coagulant activity of the venom, and suggested that the venom acted enzymically on a substrate contained in the serum. The serum factor can be partially purified by adsorption on barium sulphate and elution by 0-2m-citrat...

A new case of combined factor V-VIII deficiency is reported with in vitro studies of factors V and VIII activation by thrombin. The normal activation of factors V and VIII demonstrated in the patient's plasma and the equivalent levels of factor VIII coagulant activity and coagulant antigen support the hypothesis that a quantitative rather than qualitative defect in factors V and VIII is present...

Water scarcity encourages researchers to keep working on natural coagulant agents such as Moringa oleifera seed extract, that could be used even in developing countries. With this scope, this investigation is focused on the optimization of certain parameters affecting the use of this coagulant product in the clarification of real surface water. Acidic pH levels seem to enhance the coagulation p...

1. Human placenta microsomes active in blood coagulation have been prepared by a combination of differential centrifugation, density gradient centrifugation, and extraction with butanol-benzene mixtures. Human brain particles have been prepared from acetone-dried brain by extraction with sodium chloride solutions, differential centrifugation, and extraction with butanol-benzene mixtures. 2. Pla...

Heavy metal, chromium (VI) removal by coagulation using natural coagulant material was investigated in this paper. Chromium occurs naturally in the paint manufacturing industry waste water in many steps of the process. The coagulation and flocculation method is used for chromium removal from waste water using fruits of Opuntia Ficus indica, Fruits of Jatropha gossypifolia and peel of Borassus f...

Abstract: Artificial Neural Network (ANN) techniques are applied to the control of coagulant dosing in a drinking water treatment plant. Coagulant dosing rate is non-linearly correlated to raw water parameters such as turbidity, conductivity, pH, temperature, etc. An important requirement of the application is robustness of the system against erroneous sensor measurements or unusual water chara...

p-Nitrophenyl-p’-guanidinobenzoate is a suitable substrate for the titration of purified bovine Factor X which has been activated by a coagulant protein from Russell’s viper venom. Reaction of Factor Xa with p-nitrophenyl-P’-guanidinobenzoate occurs at the site which is responsible for the clotting activity of Factor Xa. Activation of bovine Factor X by the Russell’s viper venom coagulant prote...
