BACKGROUND Hypoxia Inducible Factors (HIF1α and HIF2α) are commonly stabilized and play key roles related to cell growth and metabolic programming in clear cell renal cell carcinoma. The relationship of these factors to discretely alter cell metabolic activities has largely been described in cancer cells, or in hypoxic conditions, where other confounding factors undoubtedly compete. These trans...

ATP-binding cassette transporters from several rhizobia and Salmonella enterica serovar Typhimurium, but not secondarily coupled systems, were inhibited by high concentrations (100 to 500 mM) of various osmolytes, an effect reversed by the removal of the osmolyte. ABC systems were also inactivated in isolated pea bacteroids, probably due to the obligatory use of high-osmolarity isolation media....

Group A streptococci of several different M serotypes can cause human plasma to clot in nutrient-poor media. Addition of glucose to the medium prevents clot formation. Once formed, clots are stable for several days and can be lysed on addition of exogenous streptokinase or urokinase. Clot lysis can also be achieved by addition of glucose to a clot containing wild-type group A streptococci but n...

The authors report on experimental results of the coccolithophore Emiliania huxleyi that was grown under nutrient replete (+N) and nitrogen limited (-N) conditions, both under a similar range of pCO2 levels / CO2 concentrations in the culture media. Each set of experiments was subjected to three concentrations of CO2 (corresponding to a "preindustrial" lower-than-modern pCO2 of ∼200-280 μatm, a...

S. griseus isolated from soil samples was screened for production of streptomycin by plate assay. Identification of streptomycin antibiotic was done by paper chromatography using selected strains of bacteria by measuring the zone of inhibition. Among all the bacterial strains studied, the highest zone of inhibition was measured against E. coli whereas lowest was measured against S. aureus after...

Kale is prospective for cultivation because they have a good market. In order to get optimal plant output when growing kale in hydroponic system, care must be taken employ AB Mix nutrients and specific planting media types. This study aim at obtaining the right combination of types on yield growth plants, which were grown substrates hydroponic. The was organized Randomized Complete Block Design...
