Chromosome spreading of the (TTAGGG)n repeats in the Pipa carvalhoi Miranda-Ribeiro, 1937 (Pipidae, Anura) karyotype
(2017-01-01)
Pipidae is a clade of Anura that diverged relatively early from other frogs in the phylogeny of the group. Pipids have a unique combination of morphological features, some of which appear to represent a mix of adaptations ...
Assignment of chromosome rearrangements between X chromosomes of human and cattle by laser microdissection and Zoo-FISH
(Springer, 2005-08-01)
Cross-species fluorescence in-situ hybridization (Zoo-FISH) was performed on cattle metaphase spreads using Homo sapiens X chromosome (HSAX) painting probes specific for the p- and q-arms to identify the cytogenetic location ...

Cytogenetic analysis of three sea catfish species (Teleostei, Siluriformes, Ariidae) with the first report of Ag-NOR in this fish family
(Sociedade Brasileira de Genética, 2010-01-01)
Despite their ecological and economical importance, fishes of the family Ariidae are still genetically and cytogenetically poorly studied. Among the 133 known species of ariids, only eight have been karyotyped. Cytogenetic ...

Supernumerary chromosomes, Robertsonian rearrangement and multiple NORs in Corydoras aeneus (Pisces, Siluriformes, Callichthyidae)
(1988-01-01)
Cytogenetic studies in four samples of Corydoras aetteus from tributaries of the Tietê River in the upper Paraná System, Brazil (rivers Araquá, Corumbataí, Capivara and Alambari) evidenced a diploid number of 2n = 60 and ...
Chromothripsis with at least 12 breaks at 1p36.33-p35.3 in a boy with multiple congenital anomalies
(2015-12-01)
Terminal deletion in the short arm of chromosome 1 results in a disorder described as 1p36 deletion syndrome. The resulting phenotype varies among patients including mental retardation, developmental delay, sensorineural ...
Insights into the origin of the high variability of multivalent-meiotic associations in holocentric chromosomes of Tityus (Archaeotityus) scorpions
(2018-02-01)
Scorpions represent an intriguing group of animals characterized by a high incidence of heterozygous chromosomal rearrangements. In this work, we examined six species of Tityus (Archaeotityus) from Brazilian fauna with a ...

Chromosomal instability in chronic myeloid leukemia: Philadelphia breakpoints are independent of spontaneous breakage and fragile sites
(Ferrata Storti Foundation, 2000-10)
Increased frequencies of spontaneous and bromodeoxyuridine induced breakages with a non-random distribution of breakpoints were found in patients with chronic myeloid scientific correspondence 1105 Haematologica vol. ...
