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...
Objective: Methanol extract of bran and unpolished grain of two traditional aromatic rice genotypes viz. Kalijira and Chinigura were assayed for their activity on the growth and initiation of crown-gall tumors on potato disks. Materials and Methods: Three Agrobacterium tumefaciens (A. tumefaciens) strain AtSl0105, AtTa0112, and AtAc0114 were used as the tumor forming agent. Collected rice was s...
Abstract Backgraound: Hypoxia is an important determinant for biological behavior of malignant solid tumors. In vitro and in vivo studies have shown that tumor hypoxia is associated with an increased likelihood of local recurrence and distant metastasis, as well as resistance to radiation therapy and certain types of chemotherapy. Studies have shown that some copper-bis thiosemicarbazones es...
Objective(s): Program death 1 (PD-1)/ program death-ligand 1 (PD-L1) pathways, as the main inhibitory checkpoints, induce immunosuppression in the tumor microenvironment (TME). Despite the importance of inhibitor checkpoint receptor (ICR) blockers, their outcomes have been limited by the low immune response rate and induced acquired resistance. Pre-existing tumor-speci...
objective(s):tumor-associated antigen (taa) subunit-based vaccines constitute promising tools for anticancer immunotherapy. however, a major limitation in the development of such vaccines is the poor immunogenicity of peptides when used alone.the aim of this study was to develop an efficient vaccine delivery system and adjuvant to enhance anti-tumor activity of a synthetic her2/neu derived pept...
