The growth requirements of 135 clinical isolates of Neisseria gonorrhoeae and six American Type Culture Collection reference strains were examined by using a simple chemically defined medium known as Wong-Shockley-Johnston medium, WSJM. The simple liquid medium supported growth of gonococci from an inoculum of 2 X 10(6) colony-forming units ml-1 and yielded 10(10) colony-forming units ml-1 in 1...

SITE model was developed to study the response of tropical ecosystems according to environmental conditions for estimating of energy fluxes. This study analyzed the net ecosystem of CO2 exchange (NEE) by ecosystem modeling and field measurements in a semi deciduous forest located at 50 km of Sinop municipal district, Mato Grosso, Brazil. Continuous measurements of canopy CO2 storage and fluxes ...

background: many azoospermic patients with non obstructive azoospermia (noa) are candidate for testicular sperm extraction (tese) and in vitro fertilization. because sperm might be present in some but not all parts of the testes of such men, multiple sampling of testicular tissue are usually necessary to increase the probability of sperm finding. sperm finding can be done by two methods: 1) cla...

Hydrogen can be a renewable energy carrier and is suggested to store mitigate carbon dioxide emissions. Subsurface storage of hydrogen in salt caverns, deep saline formations, depleted oil/gas reservoirs would help overcome imbalances between supply demand energy. Hydrogen, however, one the most important electron donors for many subsurface microbial processes, including methanogenesis, sulfate...
