Background and objectives: Silymarin is a unique flavonoid complex with documented hepatoprotective properties. Silybum  marianum hairy root culture as a source for producing silymarin has been an important strategy for study the cell signaling pathway. In the present investigation Trichoderma strains- Silybum marianum hairy root cultures interactions have been studie...

Successful adoption of new teaching and learning technologies in higher education requires the consensus of two sub-cultures, namely the technologist sub-culture and the academic sub-culture. This paper examines trends in adoption of open source software (OSS) for teaching and learning by comparing the results of a 2009 survey of 285 Chief Academic Officers and Chief Information Officers with t...

We studied adenosine triphosphate (ATP) synthesized by bacteria in tube dilution cultures to devise a rapid antibacterial susceptibility test. The ATP level was determined with a firefly (Photinus pyralis) luciferin/luciferase bioluminescence assay, which allows a direct quantifying of bacteria above 10,000 CFU/ml. At sub-MIC, total bacterial ATP levels were paralleled by increased viable bacte...

Sustained H 2 photoproduction by green alga Chlamydomonas reinhardtii is achieved under pulse-illumination superimposed on continuous low background light. Pulse-illuminated algae act as biocatalysts producing via direct water biophotolysis.

The rate of chromatid breaks was studied in cows with a history of sub-fertility by means of a test based on measurement of the average of breaks induced in lymphocytes of peripheral blood cultures. Fourteen female specimens were divided into two groups: fertile and sub-fertile. Peripheral blood lymphocytes were cultured and prepared for cytogenetic analysis. Two types of culture were establish...

The pharmacodynamic effects of subinhibitory concentrations of different beta-lactam antibiotics were investigated. A postantibiotic effect (PAE) was induced for different bacterial species by exposure to 10x MIC of several beta-lactam antibiotics for 2 h in vitro. The antibiotic-bacterial combinations used in this study were imipenem-Pseudomonas aeruginosa, benzylpenicillin-Streptococcus pneum...
