Genetic conservation of Brazilian fishes - Present state and perspectives
(Annual Review of Biomedical Sciences, 2004-12-01) [Artigo]
Natural environments have been worldwide affected by the growing impact of anthropogenic actions that promote the reduction or the extinction of several vertebrate species. Aquatic ecosystems represent one of the most ...
Programa difundindo e popularizando a ciência: a pós-graduação abrindo as portas da universidade
(Congresso de Extensão Universitária, 2007) [Trabalho apresentado em evento]
The Development of a Universal In Silico Predictor of Protein-Protein Interactions
(PLOS ONE, 2013-05-31) [Artigo]
Protein-protein interactions (PPIs) are essential for understanding the function of biological systems and have been characterized using a vast array of experimental techniques. These techniques detect only a small proportion ...
Comparative chromosome mapping of repetitive sequences. Implications for genomic evolution in the fish, Hoplias malabaricus
(BMC Genetics, 2009-07-07) [Artigo]
Background: Seven karyomorphs of the fish, Hoplias malabaricus (A-G) were previously included in two major groups, Group I (A, B, C, D) and Group II (E, F, G), based on their similar karyotype structure. In this paper, ...

No presente estudo três espécies de Lutjaninae, Lutjanus analis, L. griseus e L. synagris foram analisadas através da coloração convencional com Giemsa, banda C e coloração com nitrato de prata para identificar as Regiões ...
Identification and description of distinct B chromosomes in Cyphocharax modestus (Characiformes, Curimatidae)
(Genetics and Molecular Biology, 2008-01-01) [Artigo]
Cytogenetic analyses were performed in Cyphocharax modestus, collected at Paranapanema River and Tietê River (São Paulo State, Brazil). A karyotype with 2n = 54 chromosomes was observed in the animals from both Brazilian ...
Physical chromosome mapping of repetitive DNA sequences in Nile tilapia Oreochromis niloticus: Evidences for a differential distribution of repetitive elements in the sex chromosomes
(Micron, 2008-06-01) [Artigo]
Repetitive DNAs have been extensively applied as physical chromosome markers on comparative studies, identification of chromosome rearrangements and sex chromosomes, chromosome evolution analysis, and applied genetics. ...
Chromosomal organization and evolutionary history of Mariner transposable elements in Scarabaeinae coleopterans
(Molecular Cytogenetics, 2013-11-29) [Artigo]
Background: With the aim to increase the knowledge on the evolution of coleopteran genomes, we investigated through cytogenetics and nucleotide sequence analysis Mariner transposons in three Scarabaeinae species (Coprophanaeus ...
Occurrence of ZZ/ZW sex chromosomes in Thoracocharax stellatus fish (Characiformes, Gasteropelecidae) from the Araguaia River, south America
