Currently, the study of fibrinolysis is beset by problems of methodology (1 ). Disadvantages of many of the present methods for measurement of clot lysisincluding lysis time for the dilute blood clot, thromboelastography, euglobulin clot lysis, fibrin plate method, and caseinolytic assay (1 )-are imprecision of results and time required to perform the test (2). The electromechanical lysis timer...

Hypercholesterolemia may render atherosclerotic plaques prone to rupture. To test this hypothesis, catheters with matrix-covered balloons were implanted into the aorta of rabbits fed standard or 0. 5% cholesterol chow (n=70). In 1 month, fibrous plaques developed around the balloon. Time-dependent accumulation of cholesteryl esters and free cholesterol was detected in the plaques of the cholest...

Biochemical and enzymatic characterization for extracellular protease isolated from Cordyceps militaris cultivated on rice bran medium was investigated. C militaris produced proteolytic enzymes from 10 days after inoculation, maximum enzyme production was found at 25 days. The optimum temperature and pH of proteases production was at 25C and pH 7.0, respectively. The protease activity was obser...

Tuberculosis (TB) is a serious infectious disease caused by a bacterial pathogen. Mortality from tuberculosis was estimated at 1.5 million deaths worldwide in 2013. Development of new TB drugs is needed to not only to shorten the medication period but also to treat multi-drug resistant and extensively drug-resistant TB. Mycobacterium tuberculosis (Mtb) grows slowly and only multiplies once or t...

After our previous purificational and optimisational studies on alkaline protease from a mutant of B. licheniformis Bl8, Characterisation of the purified enzyme was done from the culture supernatant by employing various parameters. The optimum pH and temperature for the activity of alkaline protease was previously found to be 10 and 50 0 C and stable in the pH range 5.0-12.0. The thermo stabili...

The aim of this work was to study some biochemical characteristics of crude alkaline protease extracts from the viscera of goby (Zosterisessor ophiocephalus), thornback ray (Raja clavata), and scorpionfish (Scorpaena scrofa), and to investigate their applications in the deproteinization of shrimp wastes. At least four caseinolytic proteases bands were observed in zymogram of each enzyme prepara...
