Ever since the description of the t(9;22) as the cytogenetic hallmark in the majority of Chronic Myolegeneous Leukemias (CML), the analysis of chromosomal aberrations has been an important and rewarding tool in oncogenetic research as well as in clinical oncology. Although the Human Genome Project and related efforts have led to the deciphering of the genomic sequence, and although the growing ...
The discovery of genomic abnormalities present in monoclonal plasma cells has diagnostic, prognostic, and disease-monitoring implications in plasma cell neoplasms (PCNs). However, technical and disease-related limitations hamper the detection of these abnormalities using cytogenetic analysis or fluorescence in situ hybridization (FISH). In this study, 28 bone marrow specimens with known PCNs we...
The aim of study is to analyze the clinical and cytogenetic investigation on patients with PDD, MR and BAP from South Indian population. Cytogenetic analysis of 11 patients with PDD, 3 patients with BAP and 12 patients with MR were carried out by using human leukocyte culturing method and clinical analysis were carried out for all the cases with the help of physicians. A significantly higher nu...
The most frequent chromosomal aberrations in B-cell chronic lymphocytic leukemia (B-CLL) are deletions on 13q, 11q, and 17p, and trisomy 12, all of which are of prognostic significance. Conventional cytogenetic analysis and fluorescence in situ hybridization (FISH) are used for their detection, but cytogenetic analysis is hampered by the low mitotic index of B-CLL cells, and FISH depends on acc...
INTRODUCTION The prevalence of somatic chromosomal abnormalities in infertile male individuals has been reported to vary in different literatures. The aim of this study was to investigate the frequency of chromosomal aberrations among infertile men referred to the Cytogenetic Laboratory of Iran Blood Transfusion Organization Research Centre (IBTO). MATERIALS AND METHODS Chromosomal analysis w...
BACKGROUND Chromosomal aberrations identified in acute lymphoblastic leukemia (ALL) have an important role in disease diagnosis, prognosis and management. Information on karyotype and associated clinical parameters are essential to physicians for planning cancer control interventions in different geographical regions. MATERIALS AND METHODS In this study, we present the overall frequency and d...
PURPOSE Accumulating evidence indicates that intratumor heterogeneity is prevalent in multiple myeloma and that a collection of multiple, genetically distinct subclones are present within the myeloma cell population. It is not clear whether the size of clonal myeloma populations harboring unique cytogenetic abnormalities carry any additional prognostic value. EXPERIMENTAL DESIGN We analyzed t...
Lymphoma is the most frequently diagnosed hematopoietic malignancy in dogs. Untreated, the survival times are approximately one month. Chemotherapy is the current standard of care and can initiate and temporarily maintain remission, with average remission times of one year. Canine lymphoma is an established model of human non-Hodgkin's lymphoma, and studying this disease in dogs can provide ins...
This study was carried out to determine the chemoprotective potential of a polyherbal aqueous decoction comprised of Nigella sativa (seeds), Hemidesmus indicus (roots), and Smilax glabra (rhizome) against bleomycin induced cytogenetic damage in human lymphocytes. Isolated peripheral blood lymphocytes (PBLs) were exposed to bleomycin at a dose of 40 µg/mL for 2 hrs in the presence or absence of ...
PURPOSE To improve the detection of disseminated tumor cells in bone marrow (BM) and peripheral blood samples of solid tumor patients, a novel computer-assisted scanning system for automatic search, image analysis, and repositioning of these cells was developed. This system allows precise identification and quantification of tumor cells by sequential immunological and molecular cytogenetic anal...
