The physical basis of non-Mendelian segregation of a sex-linked marker was studied in sex- chromosome mutant females of eight ASF ('abnormal segregating females') lines in the flour moth, Ephestia kuehniella. Electron microscopical analysis of microspread synaptonemal complexes revealed that in one line, the Z chromosome segment that contained the dz+(More)
Artificial neural networks (ANN) methodology, molecular analyses and comparative morphology of the male postabdomen were used successfully in parallel for species identification and resolution of some taxonomic problems concerning West Palaearctic species of the genus Tachina Meigen, 1803. Supervised feed-forward ANN with back-propagation of errors was(More)
A dose-response analysis of chromosomal aberrations was performed in male progeny of gamma-irradiated males in the flour moth, Ephestia kuehniella. For comparison, several female progeny from each dose level were examined. Aberrations were detected on microspread preparations of pachytene nuclei in the electron microscope and classified according to pairing(More)
Imatinib mesylate (STI 571; Glivec) is a potent and selective tyrosine kinase inhibitor. The introduction of imatinib has chanced the philosophy of mechanisms of cancer therapy and already changed current management of patients with chronic myeloid leukemia (CML). A total of 49 patients with later chronic phase CML in whom previous therapy with interferon(More)
The AML1 gene, located in the chromosomal band 21q22, belongs to the runt domain family of genes and encodes the subunit of the core-binding factor (CBF). AML1 is normally expressed in all hematopoietic lineages and is essential for the transcriptional regulation of a number of hematopoietic specific genes. In acute leukemia three types of abnormality of(More)
The phylogeny of the insect infraorder Bibionomorpha (Diptera) is reconstructed based on the combined analysis of three nuclear (18S, 28S, CAD) and three mitochondrial (12S, 16S, COI) gene markers. All the analyses strongly support the monophyly of Bibionomorpha in both the narrow (sensu stricto) and the broader (sensu lato) concepts. The major lineages of(More)
Chronic myeloic leukemia (CML) is a malignant disease of hematopoietic stem cell characterized by the bcr/abl gene rearrangement. Allogeneic transplantation of stem cells (SCT) is a routinely used treatment method of patients with this diagnosis and remains the only curative mode of treatment. From January 1990 to December 2002, 78 patients with CML(More)
This is the first description of larva and puparium of Oplodontha rubrithorax (Macquart, 1838) from the Oriental Region. Larvae were found at a hot spring in North Thailand. The morphological features and cuticular structures of the larva are documented by drawings and SEM micrographs and the main characters are compared with the European O. viridula(More)
Molecular phylogenetic and traditional morphometric methods were applied to examine six Palaearctic taxa of the taxonomically difficult tachinid fly genus Dinera Robineau-Desvoidy (Diptera: Tachinidae), with particular reference to D. carinifrons (Fallén) and D. fuscata Zhang and Shima. Results of a phylogenetic analysis based on the mitochondrial markers(More)
