diffuse large b-cell lymphoma is the most common type of non-hodgkin lymphoma. micrornas (mirnas) are endogenous small rna, which can regulate gene expression at the post-transcriptional level. mirna profiling has shown a great potential as novel diagnostic and prognostic biomarkers. the present study was performed at the nemazee teaching hospital (shiraz, iran) from 2011 to 2013.the aim of thi...

previous series (17); i.e., mean age was 61 years, 70 patients were male, 72 patients were female. All the patients had adenocarcinoma of the large bowel; anal carcinomas were excluded. The specimens were selected only insofar as they were received unfixed and yielded enough tissue to permit immunological testing in tissue culture of the regional lymph node lymphocytes against the primary tumor...

abstract solitary pulmonary nodule (spn) is explained as a separate, well-determined obscurity with the maximum size of 3cm which is enclosed by typical lung tissue and is not related to any other anomalies in the lung or adjacent lymph nodes. among imaging modalities mri has more benefits such as high spatial resolution and usage of nonionizing radiation, however, the efficacy of this imaging ...

a 41 year old woman was referred to our center because of a left breast mass lesion of about two months duration. routine pathologic examination of the mass revealed a .neoplastic tissue composed of large ovoid cells with clear cytoplasm arranged in broad sheets that were separated by thin bundles of connective tissue. immunohistochemically tumor cells express smooth muscle actin, cytokeratin, ...

introduction: sentinel lymph node biopsy is the standard procedure for lymph node staging in intermediate thickness melanoma. in iran, this procedure has not been addressed sufficiently. in this study, we report our experience in this area. methods: ten consecutive patients with intermediate thickness melanoma where included in our study. 1.5 mci of tc-99m antimony sulfide colloid in two divide...

Most Salmonella control programmes are based on serological testing in the slaughterhouse. However, from a point of view of carcass contamination, it is rather the presence of Salmonella spp. in the animal at the time of slaughter that is important. The aim of this cross-sectional study was to investigate the possible discrepancies between the isolation of Salmonella spp. in the mesenteric lymp...

peripheral lymph nodes, located deep in the subcutaneous tissue, clean antigens from the extracellular fluid. generally, a normal sized lymph node is less than one cm in diameter. peripheral lymphadenopathy (lap) is frequently due to a local or systemic, benign, self-limited, infectious disease. however, it could be a manifestation of underlying malignancy. seventy-five percent of all laps are ...
