Evaluation of constitutional chromosome aberrations in hematologic disorders
(Elsevier Science Inc, 2002-04)
We have reviewed 4164 patients with various hematologic disorders cytogenetically studied in our laboratory during the last 25 years to analyze the frequency of constitutional chromosome aberrations (CCA) and to evaluate ...
Chromosomal abnormalities in patients with azoospermia in western Mexico
(2006)
In order to assess the frequency of chromosomal abnormalities in azoospermic males from western Mexico, we carried out a retrospective study in 227 patients. Forty-three (18.9%) cases with an abnormal karyotype were found. ...

The early evolutionary history of neo-sex chromosomes in Neotropical grasshoppers, Boliviacris noroestensis (Orthoptera: Acrididae: Melanoplinae)
(Czech Academy of Science, 2014-07)
Neo-sex chromosomes are an important component of chromosome variation in Orthoptera, particularly South American Melanoplinae species, which have proven to be outstanding experimental model system to study the mechanism ...
DNAs satélites e evolução do sistema sexual neo-XY do gafanhoto Ronderosia bergii: uma abordagem citogenômica
(Universidade Estadual Paulista (Unesp), 2020-02-17)
Uma característica comum da evolução dos cromossomos sexuais é a acumulação de DNAs repetitivos, que estão envolvidos em sua diversificação e degeneração. Em gafanhotos o sistema ancestral dos cromossomos sexuais é o XO, ...
Chromosomal abnormalities in couples with reproductive disorders
(2013)
Optimization approaches, inspired by different metaphors, have recently attracted the interest of the scientist community. On the other hand, circle detection over digital images has received considerable attention from ...
Chromosome homologies of the highly rearranged karyotypes of four Akodon species (Rodentia, Cricetidae) resolved by reciprocal chromosome painting: the evolution of the lowest diploid number in rodents
(SPRINGER, 2009)
Traditionally comparative cytogenetic studies are based mainly on banding patterns. Nevertheless, when dealing with species with highly rearranged genomes, as in Akodon species, or with other highly divergent species, ...
Clinical, Phenotypic, and Demographic Characteristics of Peruvian Children and Neonates with Autosomal and Sex Chromosome Aneuploidies
(AVESTR, 2023-02-28)
"Objective: Autosomal and sex chromosome aneuploidies are associated with multiple risk factors that determine their frequency and their social and health impact. We aimed to determine the clinical, phenotypic,
and ...
