We used comparative genomic hybridization (CGH) and conventional cytogenetics (CC) to define chromosomal changes and to evaluate the usefulness of CGH in 65 patients having childhood acute lymphoblastic leukemia (ALL). Subsequently, fluorescence in situ hybridization (FISH) was used to evaluate the CGH and cytogenetic results. Comparative genomic(More)
The unsatisfactory results of current anti-cancer therapies require the active search for new drugs, new treatment strategies and a deeper understanding of the host-tumour relationship. From this point of view, the drugs with a capacity to substitute the functions of altered tumour suppressor genes are of prominent interest. Since one of the main functions(More)
Diamond-Blackfan anemia (DBA) is a congenital red blood cell aplasia that is usually diagnosed during early infancy. Apart from defects in red blood cell maturation, the disorder is also associated with various physical anomalies in 40% of patients. Mutations in the ribosomal protein (RP) S19 are found in 25% of patients, while mutations in other proteins(More)
Diamond-Blackfan anemia (DBA) is a rare congenital pure red cell hypoplasia characterized by a selective defect of erythropoiesis with a normochromic macrocytic anemia and reticulocytopenia often accompanied by various congenital anomalies. The critical region responsible for the pathogenesis of DBA has been mapped in some patients to chromosome 19q13.2 (P(More)
The aim of our study was to assess the ERBB2 and TOP2A gene status in breast carcinoma tissue using fluorescence in situ hybridization (FISH) and to compare their amplification with immunohistochemistry assay (IHC) of the ERBB2, resp. topoisomerase IIalpha proteins. TOP2A status is important in tailored treatment as topoisomerase IIalpha is the molecular(More)
BACKGROUND The aim of this review was to summarise the experience on implementation of information technology to support the teaching and learning process in medicine. Particular attention was paid to web-based tutorials, their impact on increasing the effectiveness of medical instruction and motivation of students towards self-directed learning. Most of(More)
In pediatric acute myeloid leukemia (AML), cytogenetic abnormalities are strong indicators of prognosis. Some recurrent cytogenetic abnormalities, such as t(8;16)(p11;p13), are so rare that collaborative studies are required to define their prognostic impact. We collected the clinical characteristics, morphology, and immunophenotypes of 62 pediatric AML(More)
The spread of the internet and the evolution of the Web significantly change the way how we learn. Technology brings enhancements for learning almost on a daily basis. In this paper we discuss the role and importance of content annotations in a domain of web-based learning. We focus on collaboration support, continuous improvements of the content quality(More)
BACKGROUND Inflammatory bowel diseases (IBDs) in adolescents are chronic medical conditions with a substantial influence on the quality of life (QoL) of the families. METHODS A total of 27 adolescents suffering from IBD, 39 healthy adolescents, and their parents were included in the cross-sectional study. The adolescents completed the questionnaires ADOR(More)
