We investigated the impacts of sarA and agr on fnbA expression and fibronectin-binding capacity in Staphylococcus aureus in vitro and in experimental endocarditis. Although sarA up-regulated and agr down-regulated both fnbA expression and fibronectin binding in vitro and in vivo, fnbA expression was positively regulated in the absence of both global regulators. Thus, additional regulatory loci ...

Xara is the working name for a new version of SARA, the `SGML aware retrieval application' originally developed for use with the British National Corpus (BNC) in 1994. The system has been completely rewritten as a general purpose tool for searching large XML corpora, with a particular focus on the needs of corpus linguists, with close attention to new XML-based encoding standards, and with the ...

This trial was designed in order to evaluate the incidence of subacute rumen acidosis (SARA) during early lactation and to investigate the possibilities for its prevention by use of a buffering mineral mixture. On the beginning of the trial it was found that the pH value of rumen fluid in 4 animals was lower than normal (pH < 6.0) and that 20% of animals have had SARA. The control and the exper...

MOTIVATION Aligning RNAs is useful to search for homologous genes, study evolutionary relationships, detect conserved regions and identify any patterns that may be of biological relevance. Poor levels of conservation among homologs, however, make it difficult to compare RNA sequences, even when considering closely evolutionary related sequences. RESULTS We describe SARA-Coffee, a tertiary str...

For those unfamiliar with it, the sci.math newsgroup hierarchy is a collection of thread-based bulletin boards dealing with all aspects of mathematics. Of that hierarchy, the group sci.math is devoted to the discipline in general. On any given day, topics posted there might be by high school or college students looking for help with homework, people suggesting solutions to classical conjectures...
