The nutritional requirements and environmental conditions for a submerged culture of Streptomyces sp. 8812 were determined. Batch and fed-batch Streptomyces sp. 8812 fermentations were conducted to obtain high activity of secondary metabolites. In the study several factors were examined for their influence on the biosynthesis of the active metabolites-7-hydroxy-6-oxo-2,3,4,6-tetrahydroisoquinoline-3-carboxyl...
Enzymatic activity profiles for two morphotypes of 37 Candida albicans clinical isolates were compared. Yeast and hyphal forms were grown using yeast extract‐peptone‐glucose broth or undiluted human serum, respectively. Both morphotypes were documented under scanning electron microscopy. The api® ZYM (BioMérieux, France) test was used to evaluate the enzymatic activity profiles for particular pleomorphic...
Insecticides have leading role in reduction of population of arthropods, especially vectors of infectious diseases. Efficacy of insecticides is usually proved on biological material and described after adjusting the values of parameters in some “theoretical” function to the experimental results. In the standard approach, such function is described by probit regression. However, in some cases reaction...
The study was performed in 65 patients with HAE and 113 healthy persons. The parameters measured were C1-INH, C4, MBL concentration and MBL/MASP-2 complex activity, and serological markers of H. pylori, HBV, and HCV infection. Scores for the frequency and severity of HAE symptoms were determined. Results: HAE scores were significantly higher in patients whose C1-INH activity did not exceed 10% than...
