The authors describe a case of histiocyte-rich B-cell lymphoma (HR-BCL), a variant of diffuse large B-cell lymphoma, in a 51-year-old man. The patient presented with large axillary lymphadenopathy. Histopathologic and immunohistochemical examination of lymph node biopsy revealed diffuse effacement of the lymph node architecture by reactive histiocytes and neoplastic CD20 positive B cells. ...

marshmallow is a medicinal plant containing mucilage polysaccharides and various phenolic acids. boron (b) is an essential micronutrient whose necessity for plant growth and development has been attributed to its role in cell wall pectin network and maintenance of integrity and performance of membranes. the present study was aimed to investigate the effects of different concentrations of b (0.0...

background: mesenchymal stem cells (msc) have ability to regulate immune response via proinflamatory cytokines. in this study we aimed to investigate the effect of different mechanism for t cell activation and adjacency on immunoregulatory properties of msc. methods: bone marrow mscs were purchased and t cells were obtained from whole blood sample. t cells were activated by two different mechan...

background: various infectious agents like ebstein barr virus (ebv), htlv-1 and helicobacter pylori have known as etiologic factors in different sub-types of lymphoma. although hepatitis c virus (hcv) has not only been important for its hepatotropism and hepatitis development, but also in recent years its association with some forms of non- hodgkin’s lymphoma (nhl), especially b cell nhl, has r...

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...

conclusions it was demonstrated that the presence of del6q21 in b-cll patients indicates poor prognosis and on the contrary, presence of del17p13 points at the good prognostic value of the disease. results deletion of 17p13 was found in 11 (16.6%) and deletion 6q21 was present in 5 (7.5%). statistical analyses were performed to investigate the correlation of these molecular-cytogenetic findings...

background and objective: approximately half of patients with diffuse large b-cell lymphoma are cured with current chemotherapy regimens. the purpose of this study was to evaluate bax and bcl2 expression and their relationship with the response to chemotherapy. materials and methods this study was a prospective analysis on 44 patients with diffuse large b-cell lymphoma. their specimens were sta...

Background: Acute Lymphoblastic Leukemia (ALL) is the most prevalent cancer in childhood. ALL is a heterogeneous type of malignancy and treatment protocols vary based on the immunological classification of ALL. The critical step for treating ALL is immunological subgroup identification by flow cytometry findings. In this study, for the first time, immunophenotypic information was evaluated in c...
