1. Characterization of the complete mitochondrial genome and a set of polymorphic microsatellite markers through next-generation sequencing for the brown brocket deer Mazama gouazoubira
The complete mitochondrial genome of the brown brocket deer Mazama gouazoubira and a set of polymorphic microsatellite markers were identified by 454-pyrosequencing. De novo genome assembly recovered 98% of the mitochondrial genome with a mean coverage of 9-fold. The mitogenome consisted of 16,356 base pairs that included 13 protein-coding genes, two ribosom

2. Assessing paternity in japanese quails (Coturnix japonica) using microsatellite markers - inferences for its mating system and reproductive success
Microsatellite markers were analyzed in Japanese quails, Coturnix japonica, using different methodologies (PAGE and automated genotyping), in order to evaluate their use in paternity testing. Ten animal triplets composed by a female and two males were used to mate and generate an offspring. Paternity was determined in five-day-old embryos, and the data gener

3. Caracterização de cepas de Escherichia coli contendo diferentes alelos rpoS. / Characterization of Escherichia coli strains carrying different rpos alleles.
Escherichia coli can be found in many different habitats and has to be prepared to survive and grow under unfavorable conditions. Bacteria adaptation to different growth conditions requires an efficient control of gene expression. One of the primary forms of gene expression control is the competition between different sigma factors for the binding to the cor

4. Genetic structure and conservation of Mountain Lions in the South-Brazilian Atlantic Rain Forest
The Brazilian Atlantic Rain Forest, one of the most endangered ecosystems worldwide, is also among the most important hotspots as regards biodiversity. Through intensive logging, the initial area has been reduced to around 12% of its original size. In this study we investigated the genetic variability and structure of the mountain lion, Puma concolor. Using

5. Ancestral origin of the ATTCT repeat expansion in spinocerebellar ataxia type 10 (SCA10)
Spinocerebellar ataxia type 10 (SCA10) is an autosomal dominant neurodegenerative disease characterized by cerebellar ataxia and seizures. The disease is caused by a large ATTCT repeat expansion in the ATXN10 gene. The first families reported with SCA10 were of Mexican origin, but the disease was soon after described in Brazilian families of mixed Portuguese

6. Characterization of six microsatellite loci in Myrica faya (Myricaceae) and cross amplification in the endangered endemic M. rivas-martinezii in Canary Islands, Spain
Six novel polymorphic microsatellite markers were isolated from enriched libraries in Myrica faya Ait., recently renamed Morella faya , (fayatree, firetree, or firebush) in order to examine the genetic diversity in natural populations. Also, test cross-specific amplification and genetic diversity in Myrica rivas-martinezii, which is endemic on the Cana

7. Genetic variants of N-acetyltransferase 2, CYP2E1 and Glutathione S-transferase: relation with therapeutic safety in patients with tuberculosis / Variantes genéticas da N-acetiltransferase 2, CYP2E1 e glutationa S-transferase: relação com a segurança terapêutica em pacientes com tuberculose
Polymorphisms in N-acetiltransferase 2 (NAT2), CYP2E1 and glutatione S-transferase (GST) have been associated with differences in response to antituberculosis drugs. The role of the NAT2, CYP2E1 and GSTM1/GSTT1 variants on safety profile of the anti-tuberculosis therapy was evaluated in 99 tuberculosis patients, without co-infection by HIV or hepatitis virus

8. Uso de marcadores microssatélites para avaliação genética de populações de Melipona mandacaia Smith, 1863 (Hymenoptera, Apoidea) no Estado da Bahia / Microssatellites markers applied to genetic evaluation of populations of Melipona mandacaia Smith, 1863 (Hymenoptera, Apoidea) in Bahia State, Brazil
Melipona mandacaia, is an indigenous stingless bee (Meliponini Tribe), an endemic species of the semi-arid of the northeast of Brazil. The original flora of the caatinga has been altered by the human action. This alteration reduces the food resources and the places available for nesting, so this affects the dispersion and the genetic flow of the populations

9. Population genetic structure of the major malaria vector Anopheles darlingi (Diptera: Culicidae) from the Brazilian Amazon, using microsatellite markers
The population genetic structure of Anopheles darlingi, the major human malaria vector in the Neotropics, was examined using seven microsatellite loci from nine localities in central and western Amazonian Brazil. High levels of genetic variability were detected (5-25 alleles per locus; H E = 0.519-0.949). There was deviation from Hardy-Weinberg Equilibrium f

10. Desenvolvimento, caracterizaÃÃo e estimativas de erros de genotipagem de locos microssatÃlites de tabebuia Ãurea (bignoniaceae)
Tabebuia aurea (Bignoniaceae) is a widespread Brazilian Cerrado tree species, pollinated by large-sized bees and dispersed by wind. It is a remarkably important species for the local population of the Brazilian Cerrado, for timber logging and for homemade recipes for medical purposes. The fragmentation of the âCerradoâ vegetation in Brazil and the higher f

11. Esterase-D and chromosome patterns in Central Amazon piranha (Serrasalmus rhombeus Linnaeus, 1766) from Lake Catalão
This study presents additional genetic data on piranha (Serrasalmus rhombeus Linnaeus, 1766) complex previously diagnosed due to the presence of distinct cytotypes 2n = 58 and 2n = 60. Three esterase-D enzyme loci (Est-D1, Est-D2 and Est-D3) were examined and complemented with chromosomal data from 66 piranha specimens collected from Lake Catalão. For all s

12. Desempenho forense de microssatÃlites para a investigaÃÃo da origem de Cannabis sativa no Brasil e no Paraguai
The black market of Cannabis sativa (marijuana) in Brazil is basically supplied by illegal plantations from Paraguay, North and Northeastern Brazil. Without a well established intelligence service is difficult to state the right origin of large and small apprehensions. Any new technology that helps this task will be of inestimable value for the war against t
