It is a widely accepted notion that new and unexpected observations often have difficulty getting published and that there is therefore a delay in making the scientific community aware of new ideas. Recurring translocations are a significant feature of the chromosome aberrations in human leukemia, lymphoma, and some solid tumors. 1 Publication of the very first discovery of a translocation in m...

An adult patient with acute lymphoblastic leukemia associated with a 14q+ marker chromosome is presented. The abnormality resulted from a translocation of material from the long arm of chromosome 11. The leukemic cells were found to be B cells on the basis of surface immunoglobulins, lack of receptors for sheep erythrocytes, and a characteristically low level of adenosine deaminase activity. In...

The aim of this work is to characterize Nephilengys cruentata in relation to the diploid number, chromosome morphology, type of sex determination chromosome system, chromosomes bearing the Nucleolar Organizer Regions (NORs), C-banding pattern, and AT or GC repetitive sequences. The chromosome preparations were submitted to standard staining (Giemsa), NOR silver impregnation, C-banding technique...

Chromosome analyses were performed by isted in the chromosome changes; the nona direct method on bone marrow cells of random occurrence of some chromosome 147 patients with acute leukemia and preabnormalities was revealed, involving leukemia; in 53 chromosomally abnormal most frequently chromosomes No. 8 and cell lines were found. Chromosome abNo. 2 1 . Abnormalities of chromosome No. normaliti...

Background: Constitutional chromosome abnormalities are among the major contributors to the genetic causes of reproductive disorders. Despite all of worldwide efforts have been made so far, the prognosis for mosaic X chromosome aberration below 30% of unemployed has yet to be established. The purpose of this study was to assess the quantity and quiddity of chromosomal aberrations that may negat...

Przewalski's wild horse (E. przewalskii, EPR) has a diploid chromosome number of 2n = 66 while the domestic horse (E. caballus, ECA) has a diploid chromosome number of 2n = 64. Discussions about their phylogenetic relationship and taxonomic classification have hinged on comparisons of their skeletal morphology, protein and mitochondrial DNA similarities, their ability to produce fertile hybrid ...

The development of chromosome banding techniques has made possible the detailed analysis of human chromosomes. A vast body of knowledge has accumulated during the last few years as a result of their application in biology and medicine.
