background and aims: immunohistochemical tests are one of the most important tests, which are under study to determine the prognosis of the cancers such as transitional cell carcinoma. by the time, flexible cystoscopy and urine cytology are the routine tests for following up the patients with transitional cell carcinoma, which are both operator dependent. on the other hand, cystoscopy is an inv...
gene expression profiling of ovarian carcinoma tissues has shown an increase of four-fold expression of sort1 gene. sortilin 1 (ntr-3) is a 95-100 kda protein normally expressed in heart, brain, placenta, skeletal muscle, spinal cord, thyroid, and testis. however, its expression has never been reported in normal ovary. here, we report expression of sortilin 1 in ovarian carcinoma tissues both a...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
Background and Aim: Cutaneous squamous cell carcinoma (CSCC) is the second most common skin cancer. Mast cells may play a role in tumor progression and metastasis by increasing angiogenesis. The aim of this study was to investigate the role of mast cells by increasing angiogenesis in invasion of head and neck cutaneous squamous cell carcinoma. Materials and Methods: In this cross-sectional stud...
We examined 170 formalin-fixed paraffin-embedded samples from esophageal squamous cell carcinoma patients. All subjects live in Mazandaran province, a region with high incidence rate of esophageal cancer and have become known as the “Asian Esophageal Cancer Belt”. Samples were tested for HPV-DNA by MY09/11 and Gp5+/6+ general primers using nested PCR. Of the 170 ESCC samples, 86 (50.6%) were ma...
Squamous cell carcinoma of the gallbladder is rare and constitutes only 0.5-3% of all malignancies of this organ. Most of the reported cases have had a component of adenocarcinoma. We report a 70-year-old man who presented with acute onset right upper quadrant pain. He operated on based on a presumptive diagnosis of acute cholecystitis according to clinical and ultrasonographic findings. Histop...
Background & Aims: It was aimed to determine the relation between pathological size of renal cell carcinoma on microscopic pathological parameters of radical nephrectomy specimen. Material & Methods: In a retrospective study, we reviewed pathological finding of 76 patients that underwent radical nephrectomy during 2006-2011. We studied the relations between pathological size of tumor with nu...
Introduction : Epithelial cell carcinoma is the most common malignant neoplasm of gallbladder , but squamous cell carcinoma (SCC) is rare. Case Report: Following the diagnosis of hydropsy of gallbladder in a sonography of a 60 years-old woman, cholesistectomy was performed. On macroscopic pathological examination, brownish deformed gallbladder was seen. After opening, on mucosal surface ther...
Introduction: The changes in the level of SEPT9 gene promoter methylation can contribute to the formation of esophageal squamous cell carcinoma. The aim of this study was to evaluate the level of changes in the level of SEPT9 gene promoter methylation in the esophageal squamous cell carcinoma. Methods: In the present case-control study, we collected 75 paraffin blocks of esophageal cancer tiss...
miliary mottling on chest radiography is seen in miliary tuberculosis, certain fungal infections, sarcoidosis, coal miner’s pneumoconiosis, silicosis, hemosiderosis, fibrosing alveolitis, acute extrinsic allergic alveolitis, pulmonary eosinophilic syndrome, pulmonary alveolar proteinosis, and rarely in hematogenous metastases from the primary cancers of the thyroid, kidney, trophoblasts, and so...
