abstract guilan is a famous province in growing rice in iran. recently, due to shortage of water, farmers' desire to use groundwater in order to grow rice in northern part of iran has been increasing rapidly. the fact that rice is sensitive to water quality, caused concern about rice cultivation sustainability in the area, especially in drought years. this study was done to investigate the spat...
Purpose: Tumor cells are surrounded by a complex microenvironment. The purpose of our study was to evaluate the role of heterogeneity of the tumor microenvironment in the variability of nanoparticle (NP) delivery and efficacy. Experimental Designs: C3(1)-T-Antigen genetically engineered mouse model (C3-TAg) and T11/ TP53 orthotopic syngeneic murine transplant model (T11) representing human brea...
we report the case of a 54-year-old iranian man who presented with melena from three months prior to admission. esophagogastroduodenoscopy and colonoscopy were normal. double balloon enteroscopy showed a pedunculated tumor located in the jejunum. he underwent laparotomy and resection of a 9.5 cm tumor from the distal jejunum. histopathologic evaluation confirmed the diagnosis of an inflammatory...

background: wilms' tumor is an emberyonal tumor arising from remnants of immature renal tissue. her2/neu is an onco-protein which mediates cellular proliferation, differentiation and survival. methods: in the current study, we analyzed her2/neu expression in 40 wilms' tumors. the clinico-demographic data of 40 patients with wilms' tumor were retrieved. immunohistochemical staining for her2/neu ...
the majority of osseous tumors of the hand are benign. the surgeon who evaluates and treats osseous tumors of the hand has to be familiar with limb anatomy, tumor biology, various presentations of the tumors and the range of treatment possibilities and their limitations. lesions in the hand more often present earlier in their course than those at other sites, just because they are more likely t...
Breast cancer is the second most common worldwide and cause of death for women. Its plasticity variability suggest a multifactorial origin, with powerful influence environmental factors. Current scientific evidence pinpoints food specific nutrients as crucial factors in breast tumor development. More precisely, dietary components can actively participate suppression and/or progression by introd...
The study looked for an optimal set of genes differentiating between papillary thyroid cancer (PTC) and normal thyroid tissue and assessed the sources of variability in gene expression profiles. The analysis was done by oligonucleotide microarrays (GeneChip HG-U133A) in 50 tissue samples taken intraoperatively from 33 patients (23 PTC patients and 10 patients with other thyroid disease). In the...
