OBJECTIVES To screen methanolic leaf extracts of 21 timber-yielding plants for antibacterial activity against nine species of uropathogenic bacteria isolated from clinical samples of a hospital (Enterococcus faecalis, Staphylococcus aureus, Acinetobacter baumannii, Citrobacter freundii, Enterobacter aerogenes, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Pseudomonas aeruginos...

Hall, K.R., Iglesias-Silva, G.A. and Mansoori, G.A., 1993. Quadratic mixing rules for equations of state. Origins and relationships to the virial expansion. Fluid Phase Equilibria, 91: 67-76. Quadratic mixing rules, originally proposed by van der Waals, are used extensively in mixture calculations involving equations of state. Several ways exist to derive such mixing rules from the principles o...

oosting the function of a learning protein jams the brain with too much information, according to Ype Elgersma (Erasmus MC, Rotterdam, Netherlands), Alcino Silva (University of California, Los Angeles, CA), and colleagues. The result is a cautionary tale for those seeking to develop learning drugs. The team created mice lacking two inhibitory phosphorylation sites on CaMKII. Wild-type CaMKII is...

industry, posing an increasing threat to the unique and fearless wildlife studied by Darwin. While the island officially only had 17,000 inhabitants in 2000, many more arrived unrecorded, and some saw the national park as a nuisance and resorted to arson to clear land for their own use. The Galápagos Islands became Unesco's very first World Heritage Site in 1978, attracting yet more visitors. I...

of results: This project extended the framework of timing analysis that we developed under a previous NSF award (MIP-9014058) by adding sufficient functional (logical) content in the models to permit more accurate (less pessimistic) performance estimation while maintaining, or not significantly reducing, the level of coverage and efficiency of the functionless analysis. The most significant res...

A Sociedade Brasileira de Ortopedia e Traumatologia faz 80 anos Practicing medicine is an individual activity, since ethics and professional responsibility are personal. There is no way in which we can share responsibility regarding medical acts, nor can we ascribe ethical responsibility to institutions. On many occasions, situations with consequences that affect physicians but in which their p...
