Cytogenetic evaluation of 20 primary breast carcinomas
(1997-11-03)
Chromosome analysis was performed on samples from 20 Brazilian patients with breast cancer. All the samples were from untreated patients who presented the clinical symptoms for months or years before surgical intervention. ...
Cytogenetic analysis of Phyllomedusa distincta Lutz, 1950 (2n = 2x = 26), P. tetraploidea Pombal and Haddad, 1992 (2n = 4x = 52), and their natural triploid hybrids (2n = 3x = 39) (Anura, Hylidae, Phyllomedusinae)
(2013-08-30)
Background: Natural polyploidy has played an important role during the speciation and evolution of vertebrates, including anurans, with more than 55 described cases. The species of the Phyllomedusa burmeisteri group are ...

Loss of Y-chromosome does not correlate with age at onset of head and neck carcinoma: a case-control study
(Associação Brasileira de Divulgação Científica (ABRADIC), 2012-02-01)
Loss of Y-chromosome has been correlated with older age in males. Furthermore, current evidence indicates that Y-chromosome loss also occurs in several human tumors, including head and neck carcinomas. However, the association ...
First case of sterility associated with sex chromosomal abnormalities in a jenny
(Wiley Blackwell Publishing, Inc, 2016-09)
Chromosomal abnormalities are one of the main causes of genetic infertility in horses. Currently, their detection rate is rising due to the use of new diagnostic tools employ-ing molecular markers linked to the sex chromosome ...

DUPLICATION OF THE SHORT ARM OF THE X-CHROMOSOME IN MOTHER AND DAUGHTER
(Springer, 1993-05-01)
An 11-year-old girl with short stature, mental retardation, and mild dysmorphic features was found to have an inverted duplication of most of the short arm of the X chromosome [dic inv dup(X)(qter --> p22.3 = p22.3 --> ...
