Factor IX concentrates have been widely advocated in the treatment of haemophilic patients with factor VIII inhibitors. Five such patients were given the 'activated' factor IX concentrate--factor VIII inhibitor bypassing activity (Feiba)--for 14 separate bleeding episodes. In six of the episodes, including two with external blood loss, bleeding progressed in spite of treatment. In none of the o...

In this research, a method for producing gum tragacanth (GT) fibers is presented. Ribbon type GT of Astragalus Gummifer species were obtained from local production lands. The gum was treated with alkali to increase its process ability, and allowed to stand for a period of time to reach the proper viscosity and/or to "ripen". Samples with different ripening times were prepared and their viscosit...

Endothelium provides a specific binding site for Factor IX/IXa which can propagate activation of coagulation by promoting Factor IXa-VIII-mediated activation of Factor X. In this report the endothelial cell Factor IX/IXa binding site has been identified and the coagulant function of the receptor blocked. Studies using [3H]Factor IX derivatized with the photoaffinity labeling agent N-succinimidy...

The research aimed to apply the Taguchi method for techno-economical evaluation of Cr+6 removal using the electro-coagulation process with the aid of two different coagulants (FeCl3 and PAC). Taguchi orthogonal array L27 (313) was applied for analyzing the effect of four variables including initial pH, reaction time, current density and coagulant types in an attempt to improve the chromium remo...

Integrally-skinned asymmetric Polyetherimide/Poly (vinyl alcohol) (PEI/PVA) hollow fber membranes for pervaporation dehydration were fabricated by non-solvent induced phase inversion. PVA inside the PEI matrix could be crosslinked to provide membrane performance stability during long term operation. The effects of different PEI/PVA blend ratio, external coagulant type and...

Nonfat (0% fat), reduced-fat (11% fat), and control (19% fat) mozzarella cheeses were made using direct acidification to test the influence of three levels (0.25X, 1X, and 4X) of coagulant concentration on proteolysis, meltability and rheological properties of cheeses during 60 d of storage at 5 degrees C. Changes in meltability, level of intact alpha(s1)-casein and beta-casein (by capillary el...

This paper examines the use of chemical or electrocoagulation treatment process followed by ion-exchange process of the textile dye effluent. The dye effluent was treated using polymeric coagulant (cationic dye-fixing agent) or electrocoagulation (iron and aluminum electrode) process under various conditions such as various current densities and effect of pH. Efficiencies of COD reduction, colo...

the opuntia ficus indica mucilage was an abundant and a low cost product. in the presentpaper, it was tested as an eco-friendly flocculants for textile waste water treatment. its performance asflocculants in decolorization, cod removal and turbidity abatement was checked. the natural product wascharacterized using uv-vis and infra-red spectroscopy. the study of the effect, followed by an optimi...

Ferrate(VI) is a green and efficient water treatment agent for drinking wastewater. It widely used in because it has multi-functional uses such as oxidation, algae removal, disinfection, adsorption flocculation. does not cause secondary pollution to the environment. This paper compares ferrate(VI) with other agents discusses three methods of preparing ferrate(VI). The adsorption, control organi...
