The most common source of nosocomial infection is the urinary tract, especially if they it is drained with a urethral catheter. Catheter-associated urinary tract infections account for at least 80% of all complicated urinary tract infections and are the most common type of hospital-acquired infection. Intestinal microflora plays the leading role in the pathogenesis of catheter-associated urinary tract infections, whereas the most important risk factor for their development is the long duration of urinary catheter drainage...

Epithelial cell adhesion molecule EpCAM is a transmembrane glycoprotein that is dynamically expressed in human and murine renal epithelia during development. The levels of EpCAM in the renal epithelium are upregulated both during regeneration after ischemia/reperfusion injury and in renal-derived carcinomas. The role of EpCAM in early kidney development, however, has remained unclear. The zebrafish pronephros shows a similar segmentation pattern to the mammalian metanephric nephron, and has recently emerged as a tractable model to study the regulatory programs governing early nephrogenesis...

This paper studies the peristaltic transport of a viscoelastic fluid (with the fractional second-grade model) through an inclined cylindrical tube. The wall of the tube is modelled as a sinusoidal wave. The flow analysis is presented under the assumptions of long wave length and low Reynolds number. Caputo's definition of fractional derivative is used to formulate the fractional differentiation. Analytical solutions are developed for the normalized momentum equations. Expressions are also derived for the pressure, frictional force, and the relationship between the flow rate and pressure gradient...
