Software Process Improvement (SPI) became known in the last twenty years. SPI is crucial to augment software process capabilities in software companies to face present demanding and global market. There were numerous published studies in United States, Europe, Australia and North America. Yet, there was still being short of research and published studies on SPI in Malaysia. This research attemp...

Spi-C is an E26 transformation-specific family transcription factor that is highly related to PU.1 and Spi-B. Spi-C is expressed in developing B cells, but its function in B cell development and function is not well characterized. To determine whether Spi-C functions as a negative regulator of Spi-B (encoded by Spib), mice were generated that were germline knockout for Spib and heterozygous for...

Interleukin-1 beta (IL-1 beta) is produced primarily by stimulated monocytes, suggesting that the IL1B gene, which codes for this protein, depends upon at least one cell-type-specific factor. Our previous characterization of the IL1B promoter indicated that the region between -131 and +12 is sufficient to direct cell-type-specific expression of a reporter gene (F. Shirakawa, K. Saito, C.A. Bona...

Salmonella enterica serotype Typhi (S. Typhi) is a causative organism of typhoid fever. A number of Salmonella serovars express a capsular polysaccharide antigen known as Vi, the biosynthetic and export proteins of which are encoded within the viaB locus of Salmonella Pathogenicity Island -7 (SPI-7). SPI-7 is inserted between two partially duplicated copies of tRNA -pheU gene. We have investiga...

The purpose of this study was to determine the mechanism of action of SPI-0211 (lubiprostone), a novel bicyclic fatty acid in development for the treatment of bowel dysfunction. Adult rabbit intestine was shown to contain mRNA for ClC-2 using RT-PCR, Northern blot analysis, and in situ hybridization. T84 cells grown to confluence on permeable supports were shown to express ClC-2 channel protein...

Infections due to seafood associated Salmonella serovars are a great risk to public health. It is known that genes involved in pathogenesis of Salmonella spp. are clustered within Salmonella pathogenicity islands. Therefore, this study was aimed at detecting the prevalence of 12 different virulence associated genes coded by 4 pathogenicity islands, namely, SPI-1, SPI-2, SPI-3 and SPI-5, among 3...

The social amoeba Dictyostelium discoideum has proven to be a useful model for studying relevant aspects of the host-pathogen interaction. In this work, D. discoideum was used as a model to study the ability of Salmonella Typhimurium to survive in amoebae and to evaluate the contribution of selected genes in this process. To do this, we performed infection assays using axenic cultures of D. dis...

BACKGROUND Living kidney donors (LKDs) experience reduction in kidney function, however serum phosphate (sPi) levels are lower compared to patients with chronic kidney disease matched for reduced kidney function. Mineral metabolism adaptations that occur in LKDs have not been adequately investigated. To evaluate the effect of nephrectomy on markers of mineral metabolism in LKDs compared to heal...

Fis, one of the most important nucleoid-associated proteins, functions as a global regulator of transcription in bacteria that has been comprehensively studied in Escherichia coli K12. Fis also influences the virulence of Salmonella enterica and pathogenic E. coli by regulating their virulence genes, however, the relevant mechanism is unclear. In this report, using combined RNA-seq and chromati...

drought is the one of the repeating phenomenon in all areas with high rainfall and low rainfall climates and is known as a natural disaster. iran is one of the countries those involved with this phenomenon in different parts of it especially in river basins. tehran province due to its importance in terms of social and political faced with growing population that it would contributes to the redu...
