Establishment of rapid and non-invasive protocols to identify b-carrying individuals of psalidodon paranae
(2021-01-01)
Supernumerary, or B, chromosomes are present in several eukaryotes, including characid fish of the genus Psalidodon. Notably, Psalidodon paranae carries the most studied B chromosome variant, a macro-B chromosome. The ...
High-throughput analysis unveils a highly shared satellite DNA library among three species of fish genus Astyanax
(2017-12-01)
The high-throughput analysis of satellite DNA (satDNA) content, by means of Illumina sequencing, unveiled 45 satDNA families in the genome of Astyanax paranae, with repeat unit length (RUL) ranging from 6 to 365 bp and ...
Delimiting the Origin of a B Chromosome by FISH Mapping, Chromosome Painting and DNA Sequence Analysis in Astyanax paranae (Teleostei, Characiformes)
(Public Library Science, 2014-04-15)
Supernumerary (B) chromosomes have been shown to contain a wide variety of repetitive sequences. For this reason, fluorescent in situ hybridisation (FISH) is a useful tool for ascertaining the origin of these genomic ...
Out of patterns, the euchromatic B chromosome of the grasshopper Abracris flavolineata is not enriched in high-copy repeats
(2021-01-01)
In addition to the normal set of standard (A) chromosomes, some eukaryote species harbor supernumerary (B) chromosomes. In most cases, B chromosomes show differential condensation with respect to A chromosomes and display ...
The repetitive DNA element BncDNA, enriched in the B chromosome of the cichlid fish Astatotilapia latifasciata, transcribes a potentially noncoding RNA
(Springer, 2017-03-01)
Supernumerary chromosomes have been studied in many species of eukaryotes, including the cichlid fish, Astatotilapia latifasciata. However, there are many unanswered questions about the maintenance, inheritance, and ...
Prenatal diagnosis of i(18q) and dup(18q) cases by quantitative fluorescent PCR
(2013-09)
Particular sonographic fetal malformations are common in chromosome 18 aberrations, requiring invasive prenatal tests to confirm the diagnosis. Karyotyping is the gold standard assay in these cases, although it is a high ...

Síndrome de Klinefelter con deficiencia parcial de hormona de crecimiento
(Universidad Peruana Cayetano Heredia. Facultad de Medicina "Alberto Hurtado", 1999)
New case of non-mosaic tetrasomy 9p in a severely polymalformed newborn girl
(2003)
The phenotypic expression of an additional chromosome 9 causes a very broad clinical spectrum of anomalies. The prognosis for infants with non-mosaic tetrasomy 9p is poor, and they usually die at a very early age. CASE: ...
Single cell chromosome rearrangements in individuals with reproductive failure
(1999)
Single cell chromosome rearrangements (SCCR) are incidental findings in cell cultures. Nevertheless, some authors have implicated them in habitual abortion. Ninety individuals classified in four groups were prospectively ...
