Background: Urinary tract infection (UTI) is a common syndrom in community, especially in females. The object of this study is to determine the prevalence of most common Bacteria causing UTI and Antibiogram pattern respectively in Ahwas population. Materials & methods: In this retrospective descriptive study we gathered all urine culture results from lab centers. Results: From 48850 cases, ...

background and objectives : economic constraint of diseases arising from salmonella typhimurium causes the study of this zoonotic organism more important. most studies on identification and characterization of s. typhimurium are conducted at dna level. flagellin genes (flic and fljb genes encoding phase-1 and phase-2 flagella, respectively) are useful as a model system for studying genetic diff...

Cellular and tissue activities highly depend on environmental pH. Murine lung tissue, when cultured properly in-vitro, is a potent producer of hematopoietic growth factors. We have studied the effect of pH on the production of hematopoietic growth factors and protein synthesis by the murine lung in-vitro. Various concentrations of NaHC03 were used to adjust the pH of the culture medium unde...

A computer-assisted pattern-recognition system (ADAPT) designed to elucidate structure-activity relationships was applied to a set of retinoids, potentially useful inhibitors of carcinogenesis. A data set of 67 retinoids was used as input to the ADAPT system; their structures were entered, and their 3-dimensional configurations were optimized by a molecular modelling algorithm. Forty of these r...

Background: Human Wharton’s jelly mesenchymal stem cells (HWJMSCs) express liver-specific markers such as albumin, alpha-fetoprotein, cytokeratin-19, cytokeratin-18, and glucose-6-phosphatase. Therefore, they can be considered as a good source for cell replacement therapy for liver diseases. This study aimed to evaluate the effects of various culture systems on the hepatocyte-specific gene expr...

Glycosaminoglycan synthesis and secretion by primate arterial smooth muscle have been examined in cell culture. Mass cultures of diploid primate arterial smooth muscle cells were either double labeled with [35S]sulfate and [3H]acetate or single labeled with [3H]glucosamine for 24 h and glycosaminoglycans were extracted and isolated from the culture medium. Incorporation of labeled precursors in...

Acquiring abundant and high-purity cancer stem cells (CSCs) is an important prerequisite for CSC research. At present, researchers usually gain high-purity CSCs through flow cytometry sorting and expand them by short-term sphere culture. However, it is still uncertain whether we can amplify high-purity CSCs through long-term sphere culture. We have proposed a mathematical model using ordinary d...

To shed light on the oncogenic nature of mutant b-catenin, we introduced a form of the cDNA that lacked an entire exon 3 into L cells derived from murine s.c. tissue. Aberrant b-catenin protein accumulated in the cytoplasm and nuclei of these cells (designated L-MT), whereas in L cells transfected with wild-type b-catenin (designated L-N), normal b-catenin protein was expressed at a level simil...
