Background Mediastinum harbors a mixed bag of neoplastic lesions with varied therapeutic and prognostic implications. Distinguishing pulmonary squamous cell carcinoma from thymic carcinoma is a challenging task owing to rather nonspecific clinicoradiological features and a considerable overlap in histomorphological features. Thus, we evaluated the diagnostic utility of cluster of differentiatio...
A total of 97 acute promyelocytic leukemia (APL) patients with adequate flow cytometry (FC) data, bone marrow aspirates and presence of t(15;17)/PML-RARA by cytogenetics and/or FISH studies were analyzed for immunophenotypic pattern. Leukemic cells had the following phenotype: CD11b-, CD11c-, CD13+, CD33+, CD45+, CD64+/-, CD117+, and HLA-DR-. A subset of cases showed also an expression of CD2, ...
Ras guanine nucleotide-releasing protein-4 (RasGRP4) is an evolutionarily conserved calcium-regulated, guanine nucleotide exchange factor and diacylglycerol/phorbol ester receptor. While an important intracellular signaling protein for CD117+ mast cells (MCs), its roles in other immune cells is less clear. In this study, we identified a subset of in vivo-differentiated splenic CD117+ dendritic ...
OBJECTIVE We aimed to review our archives in order to evaluate both the diagnostic and prognostic significance of DOG1 on gastrointestinal stromal tumors (GISTs), and add further insight about those issues to the current literature including some conflicting results. MATERIAL AND METHOD DOG1 was evaluated in 100 cases of GISTs, immunohistochemically. Immunostaining index was counted for each ...
BACKGROUND Hematopoietic progenitor cells (HPC), identified by expression of the CD34 surface antigen, show morphological and phenotypic heterogeneity in bone marrow (BM) and peripheral blood (PB). METHODS CD34+ HPC subpopulations present in 18 PB leukaphereses after high-dose chemotherapy in cancer patients and in 11 BM samples from patients with stage IA lymphoma were characterized. In orde...
Letters to the Editor will be published, if suitable, as space permits. They should not exceed 1000 words (typed double-spaced) in length and may be subject to editing or abridgment. To the Editor: I read with interest the article by Tsuji et al, 1 as well as the related editorial, 2 that appeared recently in Circulation Research. Although the findings and differentiation data of the study were...
background periapical lesions are induced in response to injuries to periapical tissues, which are generally the result of infections within the root canal. mast cells actively participate to the inflammatory infiltration of periapical granulomas and cysts. objectives the aim of this study was to detect and compare the presence of mast cells in inflammatory periapical lesions, including cysts a...
