1. Montagem de cariótipos de peixes assistida por computador
RESUMO A obtenção de cariótipos de peixes desempenha um papel importante em estudos de citotaxonomia e evolução cromossômica das espécies. No entanto, poucos sistemas semi ou completamente automatizados para a obtenção de cariótipo de peixes estão disponíveis. Este trabalho propõe e avalia uma ferramenta baseada em imagens que auxilie a montagem

2. Treatment with dasatinib or nilotinib in chronic myeloid leukemia patients who failed to respond to two previously administered tyrosine kinase inhibitors - a single center experience
OBJECTIVE:To evaluate hematological, cytogenetic and molecular responses as well as the overall, progression-free and event-free survivals of chronic myeloid leukemia patients treated with a third tyrosine kinase inhibitor after failing to respond to imatinib and nilotinib/dasatinib.METHODS:Bone marrow karyotyping and real-time quantitative polymerase chain

3. Identifying the similarities and differences between single nucleotide polymorphism array (SNPa) analysis and karyotyping in acute myeloid leukemia and myelodysplastic syndromes
Objective: To standardize the single nucleotide polymorphism array (SNPa) method in acute myeloid leukemia/myelodysplastic syndromes, and to identify the similarities and differ- ences between the results of this method and karyotyping. Methods: Twenty-two patients diagnosed with acute myeloid leukemia and three with myelodysplastic syndromes were studied.

4. Diversity of breakpoints of variant Philadelphia chromosomes in chronic myeloid leukemia in Brazilian patients
Background: Chronic myeloid leukemia is a myeloproliferative disorder characterized by the Philadelphia chromosome or t(9;22)(q34.1;q11.2), resulting in the break-point cluster regionAbelson tyrosine kinase fusion gene, which encodes a constitutively active tyrosine kinase protein. The Philadelphia chromosome is detected by karyotyping in around 90% of chro

5. Genetic evaluation of mesenchymal stem cells by G-banded karyotyping in a Cell Technology Center
OBJECTIVE: To present the initial results of first three years of implementation of a genetic evaluation test for bone marrow-derived mesenchymal stem cells in a Cell Technology Center.METHODS: A retrospective study was carried out of 21 candidates for cell therapy. After the isolation of bone marrow mononuclear cells by density gradient, mesenchymal stem ce

6. Tumor suppressor p53 protein expression: prognostic significance in patients with low-risk myelodysplastic syndrome
BACKGROUND: At the time of diagnosis, more than 50% of patients with myelodysplastic syndrome have a normal karyotype and are classified as having a favorable prognosis. However, these patients often show very variable clinical outcomes. Furthermore, current diagnostic tools lack the ability to look at genetic factors beyond karyotyping in order to determine

7. Análise dos resultados dos procedimentos invasivos para estudo do cariótipo fetal / Fetal maternal results following invasive procedures for fetal kariotype
Objective: The purpose of this study is to characterize the indications of pregnant women who seek the Fetal Medicine Service of Hospital das Clínicas of São Paulo University to perform invasive diagnostic procedures and evaluate the results of fetal karyotypes and their pregnancies from February 2005 to December 2009. Methods: Retrospective observational

8. Cytogenetics, JAK2 and MPL mutations in polycythemia vera, primary myelofibrosis and essential thrombocythemia
BACKGROUND: The detection of molecular and cytogenetic alterations is important for the diagnosis, prognosis and classification of myeloproliferative neoplasms. OBJECTIVE: The aim of this study was to detect the following mutations: JAK2 V617F, JAK2 exon 12 and MPL W515K/L, besides chromosomal abnormalities. Furthermore, molecular and cytogenetic alterations

9. Karyotypic and fluorescent in-situ hybridization study of the centromere of chromosome 7 in secondary myeloid neoplasms
BACKGROUND: Secondary myeloid neoplasms comprise a group of secondary diseases following exposure to myelotoxic agents or due to congenital diseases. The improvement of anticancer agents and immunosuppressive drugs seem to be associated with an increased incidence of secondary myeloid neoplasms. Karyotyping of bone marrow is essential for diagnosis and progn

11. Value of morphotyping for the characterization of Candida albicans clinical isolates
Until recently, morphotyping, a method evaluating fringe and surface characteristics of streak colonies grown on malt agar, has been recommended as a simple and unexpensive typing method for Candida albicans isolates. The discriminatory power and reproducibility of Hunter's modified scheme of Phongpaichit's morphotyping has been evaluated on 28 C. albicans i

12. Investigation of Candida albicans transmission in a surgical intensive care unit cluster by using genomic DNA typing methods.
An apparent outbreak of serious Candida albicans infections (n = 6) occurred in a surgical intensive care unit over a 4-week period. Four patients developed C. albicans bloodstream infections. An additional patient developed catheter-related C. albicans infection; the sixth patient developed an infection of cerebrospinal fluid. C. albicans was isolated from
