1. Muscle can be prepared in the form of a dry powder in which myosin exists in a state similar to that in intact muscle. As in intact muscle, myosin in powdered muscle is soluble and can be caused to rapidly coagulate. 2. Restoring to powdered muscle the quantity of water previously removed causes coagulation of myosin. The rate of coagulation is considerably slower at 0 degrees than at 20 deg...

background: endoscopic therapies can decrease the morbidity of patients with high risk peptic ulcer. the aim of this study was to evaluate the beneficial effects of oral omeprazole therapy in patients with bleeding peptic ulcer who received combined endoscopic treatment (epinephrine injection and argon plasma coagulation). materials and methods: eighty six patients with bleeding from gastric, d...

objective(s): echis carinatus is one of the venomous snakes in iran. the venom of iranian echis carinatus is a rich source of protein with various factors affecting the plasma protein and blood coagulation factor. some of these proteins exhibit types of enzymatic activities. however, other items are proteins with no enzymatic activity.   materials and methods: in order to study the mechanism an...

conclusions based on our results, it seems that there were no cases of obi among chronic hcv-infected patients with thalassemia and bleeding disorders, particularly hemophilia. however, to improve decisions concerning obi screening, especially in transfusion centers, and concerning the use of comprehensive screening methods, more original studies with more precise laboratory techniques and larg...

coagulants exert a significant influence on removing turbidity, tss and cod. this study has examined the effects of poly-aluminium chloride (pac), aluminium sulphate (alum) and ferric chloride on removal of turbidity, tss, cod from greywater in residential complexes of miners working in decorative stone mines. also, a comparison was undertaken with the electrocoagulation system to find out whet...

this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...

infection with human immunodeficiency virus (hiv) is a progressive condition which may cause endothelial dysfunction and liver damage leading to coagulopathy. with adventure of highly active antiretroviral therapy (haart), life expectancy has prolonged in hiv positive patients but several acquired immunodeficiency syndrome (aids)-related conditions such as coagulopathies are responsible for ass...

background: nitrate is an acute and well-known hazardous contaminant, and its contamination of water sources has been a growing concern worldwide in recent years. this study evaluated the feasibility of nitrate removal from water using the traditional coagulants alum and ferric chloride with lower concentrations than those used in the conventional coagulation process. methods: in this research,...
