To determine the incidence of leukemia-specific rearrangements, 60 cases of childhood acute myeloblastic leukemia and transient myeloproliferative disorder were screened with a novel multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) assay, and the results were correlated with the cytogenetic findings. The RT-PCR assay detects 28 different fusion genes and more than 80 different...
Background: Pancytopenia is a manifestation of a wide range of disorders. The main prognostic factor for predicting outcome and response to treatment is based on the underlying cause. To detect the root cause of this problem, depending on other accompanied signs or symptoms, the need for bone marrow examination and other advanced work ups is different at least at the practical level. This study...
BACKGROUND AND OBJECTIVE Cytogenetic analysis of acute leukemia yields important information which has been demonstrated to be correlated to patient survival. A reference laboratory was created in order to perform karyotype analysis on all cases of acute leukemia enrolled in the AIEOP (Associazione Italiana Emato-Oncologia Pediatrica) protocols. METHODS From January 1990 to December 1995, 111...
Cytogenetic analysis has not only provided important information on the pathogenesis of soft tissue tumors but, by disclosing distinct chromosomal rearrangements in different histopathological entities, has also come to serve as a valuable diagnostic tool. Little is known as yet about the potential prognostic impact of cytogenetic features detected in these tumors. A total of 239 benign and 221...
Great apes are mammals close to humans in their genetic, behavioral, social and evolutionary characteristics and new genomic information is revolutionizing our understanding of evolution in primates. However, all these species are endangered. While there are many global programs to protect these species, the International Union for Conservation of Nature (IUCN) projects that in a near future th...
introduction: most of the hematologic malignancies are heterogenous with regard to morphology, immunophenotype, and genetic rearrangements. multiple recurrent chromosomal aberrations have been identified by conventional cytogenetic analysis, which is now widely recognized as one of the most important diagnostic and prognostic determinants in these patients. patients and methods: bone marrow sam...
BACKGROUND The difference in prognosis of adult and childhood acute lymphoblastic leukemia (ALL) can be attributed largely to variation in cytogenetic abnormalities with age groups. Cytogenetic analysis in acute leukemia is now routinely used to assist patient management, particularly in terms of diagnosis, disease monitoring, prognosis and risk stratification. Knowing about cytogenetic profile...
introduction: fragile x syndrome (fxs) is one of the most prevalent genetic causes of developmental disability, representing the most frequent form of inherited severe cognitive deficit. the present study was undertaken to investigate fxs and its prevalence in moderate mentally retarded people in patients. materials and methods: nineteen people with moderate mental retardation (mr) who were cli...
