aim : the aim of this study was to assess the incidence of irritable bowel syndrome in women undergoing hysterectomy and tubular ligation. background : the results of previous studies have shown an increased incidence of irritable bowel syndrome after gynecological surgeries. patients and methods : participants were patients of alzahra and taleghani university hospitals in tabriz. one hundred a...

polycrystalline mfi zeolite membranes were prepared on α-alumina tubular support by hydrothermal treatments at 413 k. the synthesized zeolite membranes were characterized by xrd, sem and single gas permeation. the influence of hydrothermal treatment steps and the calcination time on the zeolite layer formation were investigated. mfi zeolite membrane prepared by four subsequent hydrothermal trea...

Balkan endemic nephropathy (BEN) is a chronic tubulointerstitial disease of unknown etiology. The main morphological feature is interstitial fibrosis and tubular atrophy with absence of inflammatory infiltration. The pathogenesis of BEN is also obscure. Since tubular epithelial cells in the early phase of disease express vimentin as mesenchymal marker in addition to cytokeratin, we could specul...

support the second possibility [1–6]. It was reported that chemokines produced by proximal tubular cells promoted the infiltration [3,4]. Proximal tubular epithelial cells activate urinary complement proteins in situ and contribute to the mediation of tubulointerstitial injury [6]. The tubular epithelial cell is the major site of M-CSF production within the injured kidney; macrophage accumulati...

the current study conducted a finite element (fe) and experimental investigation on tubular channel angular pressing as a noble severe plastic deformation technique for producing ultrafine grained and nanostructure tubular components. to examine the effects of the tcap process on the strain distribution and deformation behavior, fe simulations were employed. the fe results demonstrated that equ...

in the present work, b-zsm-5 zeolite membranes were synthesized on porous tubular α-alumina supports by several subsequence in situ crystallization hydrothermal treatments. the tio2- bohmite and ɣ- alumina intermediate layers were applied to improve the lattice matching between zeolite layer and the support. the uniform membrane intermediate layers with low permeation resistance were prepared o...

The importance of developing innovative support structure for underground mines has drawn much attention with the depletion shallow resources. This paper presents a hybrid tubular standing consisting an exterior container made polyvinyl chloride (PVC) and fibre-reinforced polymer (FRP) while infill is coal rejects based backfill material. FRP jacket featured high strength-to-weight ratio attach...
