Entoepidemiology of Chagas disease in the Western region of the State of S�£o Paulo from 2004 to 2008, and cytogenetic analysis in Rhodnius neglectus (Hemiptera, Triatominae)
Authors: K.C.C. Alevi, L.A.C Rodas, E. Tartarotti, M.T.V. Azeredo-Oliveira and M.M. Guirado
To complement the epidemiological data and assist in the prophylaxis of Chagas disease in the State of São Paulo, we examined entomological lifting conducted in 40 municipalities of the Western region of the state from 2004 to 2008, highlighted the main vector species in this region, and reanalyzed the cytogenetic characteristics of Rhodnius neglec..

Cytogenetic studies in Brazilian marine Sciaenidae and Sparidae fishes (Perciformes)
Authors: I.V. Accioly and W.F. Molina
Fishes from the families Sciaenidae and Sparidae, the former comprising coastal species associated with shallow waters on the continental shelf and the latter composed of typically marine species, are of significant economic value. Karyotypic data are available for about 20% of the total number of species in these groups. In t.. Read More»

Mitotic behavior in root tips of Brachiaria genotypes with meiotic chromosome elimination during microsporogenesis
Authors: M.F. Felismino, N. Silva, M.S. Pagliarini and C.B. Valle
Three accessions of Brachiaria brizantha, three of B. humidicola, and two interspecific hybrids between B. ruziziensis and B. brizantha were analyzed with regard to their mitotic behavior in root tips. All these genotypes revealed chromosome elimination or lack of chromosome affinity in previous analyses of microsporogenesis. .. Read More»

Cytogenetic analysis in the spermatogenesis of Triatoma melanosoma (Reduviidae; Heteroptera)
Authors: V.B. Bardella, M.T.V. Azeredo-Oliveira and E. Tartarotti
Triatomines are of great concern in public health because they are vectors of Chagas’ disease. This study presents an analysis of the species Triatoma melanosoma. The cytogenetic characteristics of triatomines include holocentric chromosomes, post-reductional meiosis in the sex chromosomes and nucleolar fragmentation in .. Read More»

Simultaneous presence of bovine papillomavirus and bovine leukemia virus in different bovine tissues: in situ hybridization and cytogenetic analysis
Authors: A. Yaguiu, M.L.Z. Dagli, E.H. Birgel Jr., B.C.A. Alves Reis,O.P. Ferraz, E.M. Pituco6, A.C. Freitas, W. Be�§ak and R.C. Stocco
Bovine papillomavirus (BPV) DNA sequences were detected in different tissues, in addition to epithelium. Cytogenetic abnormalities were observed in blood lymphocytes. The presence of more than one virus in a single tissue is a difficult aspect to evaluate,especially when the DNA sequences are detected in tissues that are not s.. Read More»

Subtelomeric region of chromosome 2 in patients with autism spectrum disorders
Authors: A. Barbosa-Gon�§alves, C.B. Vendrame-Goloni, A.L.B. Martins and A.C. Fett-Conte
Autism spectrum disorders are severe psychiatric diseases commonly identified in the population. They are diagnosed during childhood and the etiology has been much debated due to their variations and complexity. Onset is early and characterized as communication and social interaction disorders and as repetitive and stereotyped.. Read More»

Philadelphia-negative chromosomal evolution during treatment for chronic myeloid leukemia
Authors: H.-H. Hsiao, Y.-C. Liu, C.-P. Lee, C.-S. Chang and S.-F. Lin
Chromosome evolution is one of the major mechanisms of disease progression and resistance in chronic myeloid leukemia (CML) patients. However, the clinical significance of chromosomal evolution in the Philadelphia (Ph)-negative clone during therapy is not fully understood. We evaluated 94 CML patients in the chronic phase of C..

Chromosome number and cytogenetics of Euphorbia heterophylla L.
Authors: J.R. Aarestrup, D. Karam and G.W. Fernandes
Euphorbia heterophylla L. (Euphorbiaceae) is a herbaceous species of great economic importance due to its invasive potential and consequent damage to agriculture and pasture land. For the first time, we provide information on its chromosome number, morphology, and behavior of mitotic chromosomes. Seeds were germinated and subm.. Read More»

Chromosomal characteristics and karyotype evolution of Oxyopidae spiders (Araneae, Entelegynae)
Authors: L.M. St�¡vale, M.C. Schneider, A.D. Brescovit and D.M. Cella
We made a cytogenetic analysis of four species of Oxyopidae and compared it with the karyotype data of all species of this family. In Hamataliwa sp, the mitotic cells showed 2nâÃ?Â?Ã?Â? = 26+X1X2 and telocentric chromosomes. The 2nâÃ?Â?Ã?Â? = 28, which has been described for only one oxyopid spider, is the highest .. Read More»

A genetic linkage study in Brazil identifies a new locus for persistent developmental stuttering on chromosome 10
Authors: C.E.F. Domingues, C.M.C. Olivera, B.V. Oliveira, F.S. Juste,C.R.F. Andrade4, C.M. Giacheti, D. Moretti-Ferreira and D. Drayna
Although twin, adoption, and family studies demonstrate that genetic factors are involved in the origins of stuttering, the mode of transmission of the disorder in families is not well defined and stuttering is considered a genetically complex trait. We performed a genome-wide linkage scan in a group of 43 Brazilian families, each containing multiple case.. Read More»
