The mutagenic potential of Clusia alata (Clusiaceae) extract based on two short-term in vivo assays
Authors: A.C.G. Moura, F.F. Perazzo and E.L. Maistro
We examined the genotoxic and mutagenic effects of a crude extract of Clusia alata (a potential medicinal plant) on peripheral leukocyte and bone marrow cells of mice, using the comet and chromosome aberration assays. Extracts at doses of 1000, 1500 and 2000 mg/kg were administered by gavage, and a positive control, N-nitroso-N-ethylurea (50 mg/kg) was in.. Read More»

Karyotype and spermatogenesis in Triatoma lenti (Hemiptera: Triatominae), a potential Chagas vector
Authors: K.C.C. Alevi P.P. Mendon�§a M. Succi N.P. Pereira J.A. Rosa M.T.V. Azeredo-Oliveira
All species of Triatominae are susceptible to infection by Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae) and consequently, potential insect vectors of Chagas disease. Currently, there are 140 known species of triatomine bugs, which can be grouped into specific species complexes. The species Triatoma lenti (Hemiptera: Triatominae) is found only in B.. Read More»

Molecular sexing of unusually large numbers of Spheniscus magellanicus (Spheniscidae) washed ashore along the Brazilian coast in 2008
Authors: E.C. Reis, R.M. Aires, J.F. Moura, C.A.R. Matias, M. Tavares, P.H. Ott, S. Siciliano and G. L�´bo-Hajdu
There have been few studies on Magellanic penguins (Spheniscus magellanicus). In 2008, these penguins washed ashore along the Brazilian coast in unusually high numbers, some reaching as far as northeast Brazil. As Magellanic penguins show little sexual dimorphism, sex determination by morphological features is not accurate. He.. Read More»

Genotoxicity and mutagenicity of Rosmarinus officinalis (Labiatae) essential oil in mammalian cells in vivo
Authors: E.L. Maistro, S.F. Mota, E.B. Lima, B.M. Bernardes and F.C. Goulart
Rosmarinus officinalis (rosemary) oil is widely used by the cosmetic, food, and pharmaceutical industries as a fragrance component of soaps, creams, lotions, and perfumes. Although it is popular, potential harmful side-effects of the oil have been described. We investigated the genotoxic and mutagenic potential of essential oi.. Read More»

Chromosomes of Gymnothorax funebris and the karyotypical differentiation within Gymnothorax (Anguilliformes: Muraenidae)
Authors: M.A.O. Alves1, J.E. Monteiro-Junior1, C.A.M. Oliveira1, R.M. Silveira1, I.R. Costa1 and R. Maggioni2
Cytogenetic studies in Gymnothorax funebris revealed a diploid chromosome number 2n = 42 (6 metacentrics, 4 submetacentrics, and 32 acrocentrics, FN = 52). The results obtained are novel and similar to those previously described for species belonging to Muraenidae family. The conventional karyotype is also novel and divergent .. Read More»

Spermatogenesis and karyotypes of three species of water striders (Gerridae, Heteroptera)
Authors: M.M.U. Castanhole, L.L.V. Pereira, H.V. Souza and M.M. Itoyama
Although they are of economic importance, there have been few cytogenetic studies of the Gerridae (Heteroptera) in Brazil. We examined spermatogenesis (meiosis and spermiogenesis) and nucleolar behavior in three species of the family Gerridae. Brachymetra albinerva and Halobatopsis platensis were found to have a chromosome com.. Read More»

Karyotype diversity of four species of the incertae sedis group (Characidae) from different hydrographic basins: analysis of AgNORs, CMA3 and 18S rDNA
Authors: M.M. Mendes, R. da Rosa, L. Giuliano-Caetano and A.L. Dias
A large number of genera in the tropical fish family Characidae are incertae sedis. Cytogenetic analysis was made of four of these species: Astyanax eigenmanniorum, Deuterodon stigmaturus, Hyphessobrycon luetkenii, and H. anisitsi, collected from various hydrographic basins: hydrographic system from Laguna dos Patos/RS, Traman..

Different responses to doxorubicin-induced chromosome aberrations in Brazilian deer species
Authors: D.S.F. Vargas-Munar, J.A. Sarria-Perea and J.M.B. Duarte
The tendency toward chromosome fragility is one of the theories that may explain chromosome variation in brocket deer species (genus Mazama). We tested doxorubicin as an inducer of chromosome aberrations in lymphocytes of three brocket deer species, Mazama gouazoubira, M. americana and M. nana, compared to the marsh deer, Blas.. Read More»

Worldwide diversity of the Y-chromosome tetra-local microsatellite DYS464
Authors: F.S.G. Kehdy and S.D.J. Pena
Of all DNA markers on the human Y-chromosome, the tetra-local Y-linked microsatellite DYS464 is the most polymorphic. We genotyped DYS464 in 677 male samples collected worldwide, maintained in the HGDP-CEPH Human Genome Diversity Cell Line Panel. Fourteen different alleles were found, with allele lengths varying from 9 to 23 r.. Read More»

Detection of novel SNPs and mapping of the fatness QTL on pig chromosome 7q1.1-1.4 region
Authors: W.H. Huang, Z.X. Ma, Z.Y. Xu, Y.Z. Xiong and B. Zuo
Many QTLs for fatness traits have been mapped on pig chromosome 7q1.1-1.4 in various pig resource populations. Eight novel markers, including seven SNPs and one insertion or deletion within BTNL1, COL21A1, PPARD, GLP1R, MDFI, GNMT, ABCC10, and PLA2G7 genes, as well as two previously reported SNPs in SLC39A7 and HMGA1 genes, we..
