Vitamins k is an important fat-soluble vitamin that can be obtained from plants, bacteria and animals necessary for the blood clotting. It plays a key function as cofactor in synthesizing of clotting proteins liver; recently, interest its functions extra-hepatic tissue has increased. Vitamin deficiency usually caused by abnormal absorption rather than lack food. Apart impact on clotting, chroni...

It has been proposed that anticoagulant activity during continuous renal replacement therapy with nafamostat mesilate can be monitored by using intra-circuit activated clotting time. However, it is still unclear whether activated clotting time would be useful for this purpose. We conducted a retrospective study and included 76 patients who required continuous renal replacement therapy using naf...

ASSAY PRINCIPLE: The method is a clotting assay where all the clotting factors are present (constant and in excess, brought by the deficient plasma), excepted for FII, which is brought by the diluted tested plasma, and clotting is triggered with calcium thromboplastin. FII is the limiting factor and clotting time is inversely proportional to the concentration of FII. There is an inverse linear ...

OBJECTIVES To investigate the in vitro effects of Sodium Tetradecyl Sulphate (STS) and Polidocanol (POL) on clotting tests, clotting factors, platelets and microparticles. MATERIALS AND METHODS Platelet rich (PRP) and platelet poor (PPP) plasmas were incubated with varying concentrations of STS and POL. Clotting tests, platelet/plasma turbidity, and microparticle studies were performed. Speci...

milk clotting enzyme (m ce) produced by: rhizomucor miehei was purified and characterized.the enzyme was purified 220.29-fold with specific activity about 14444.2 u/mg protein byultrafiltration, ammonium sulfate fractionation, sephacryl s-300 chromatography. the maximumenzyme activity was at 65°c.the milk clotting activity was decreased steadily as ph is increased and indicated maximumactivity ...
