Background: DNA amplification method has been developed for identifying and discriminating Salmonella serovars, using specific primers at the genus and serovar levels and to identify the S. Enteritidis, S. Dublin, S. Gallinarum and S. Pullorum. Objectives: This study was conducted for molecular identification and discrimination among some important Salmonella serovars. Methods: Fifty isolates o...

We use a network of workstations to compute all pairwise alignments of the 500 bp upstream regions of 6,225 yeast ORFs (Open Reading Frames). We correlate the alignments with DNA microarray expression data from budding yeast cells over an oxidative stress time course. We connrm on a genomic scale that, in general, genes with extremely similar upstream regions have similar activity levels, even ...

the public’s imagination, through the stories of past heroic explorations, the endearing wildlife, the awe-inspiring geography of the Antarctic ice sheets, and the unique modes of human habitation in the Arctic. Outcomes from the forthcoming International Polar Year (IPY) will highlight the scientific importance of the regions, emphasizing their key roles in the global climate system. Over the ...

The poly(A)-binding protein (PABP), in a complex with the 3'poly(A) tail of eukaryotic mRNAs, plays important roles in the control of translation and message stability. All known examples of PABP mRNAs contain an extensive A-rich sequence in their 5' untranslated regions. Studies in mammalian cells undergoing growth stimulation or terminal differentiation indicate that PABP expression is regula...
