1. A multicenter study of oral health behavior among adult subjects from three South American cities
Abstract The aims of this study were to describe the self-reported oral hygiene habits, dental visit frequency, and gingival bleeding perception in adult populations from three South American cities, and also to assess the association of these variables with sociodemographic data and with the clinical presence of plaque and gingival inflammation. Five-hundre

2. D-loop haplotype diversity in Brazilian horse breeds
Abstract The first horses were brought to Brazil by the colonizers after 1534. Over the centuries, these animals evolved and adapted to local environmental conditions usually unsuitable for exotic breeds, thereby originating locally adapted Brazilian breeds. The present work represents the first description of maternal genetic diversity in these horse breeds

3. The invasive spotted-wing Drosophila (Diptera, Drosophilidae) has been found in the city of São Paulo (Brazil)
The invasive spotted-wing Drosophila (Diptera, Drosophilidae) has been found in the city of São Paulo (Brazil). Drosophila suzukii (Matsumura, 1931), the cherry fly or spotted-wing Drosophila, a pest species from the Oriental and southeastern Palaearctic regions belonging to the melanogaster group, invaded the Nearctic and western countries of the Palaearct

4. Sequence variation in the melanocortin-1 receptor (MC1R) pigmentation gene and its role in the cryptic coloration of two South American sand lizards
In reptiles, dorsal body darkness often varies with substrate color or temperature environment, and is generally presumed to be an adaptation for crypsis or thermoregulation. However, the genetic basis of pigmentation is poorly known in this group. In this study we analyzed the coding region of the melanocortin-1-receptor (MC1R) gene, and therefore its role

5. Levoglucosano e íons solúveis em água no material particulado atmosférico MP10 e MP2,5. caracterização de sítios Sul-Americanos / Levoglucosan and water-soluble ions in atmospheric particulate matter PM10 e PM2,5. Characterization of south american sites
A composição química do material particulado fino (MP2,5) e MP10 foi determinado em três sítios representativos do estado de São Paulo: Cidade Universitária (SPA), Piracicaba (PRB) e São Luis do Paraitinga (MAT); e em duas outras cidades sul-americanas, Bogotá (BOG) e Buenos Aires (BAI). As coletas ocorreram nos anos de 2007, 2008 e 2009. Para carac

6. Análise da dispersão das populações nativas americanas: uma abordagem genético-fisiográfica / Dispersion analysis of the native american populations: a genetic-fisiographyc approach
Until recently, the settlement of the Americas was seen as the product of a \"bow wave\" human expansion from north do south. Under this scenario, the archaeological sites of the first americans should obey a chronological gradient following the same logic, independent of their longitude. Recently, however, specialists began to recognize that certain charact

7. Abiotic factors controlling the establishment and abundance of the invasive golden mussel Limnoperna fortunei.
Limnoperna fortunei (Bivalvia, Mytilidae), a freshwater bivalve native to Southern Asia, has been an invasive species in South America since 1991. It spread upstream in the La Plata basin reaching the Paraguay River in the vicinity of the Pantanal wetland, Brazil, around 1998. The role of abiotic factors in controlling establishment and abundance of this spe

8. Hábito alimentar da rã invasora Lithobates catesbeianus (Shaw, 1802) e sua relação com anuros nativos na Zona da Mata de Minas Gerais, Brasil / Feeding habits of the invasive frog Lithobates catesbeianus (Shaw, 1802) and its relationship with native anurans in the Zona da Mata of Minas Gerais state, Brazil
The American Bullfrog (Lithobates catesbeianus) was introduced into several countries for commercial breeding, settling invasive populations during this process. In Brazil the beginning of its farming occurred on the 1930 s, and currently invasive populations can be found in the South, Southeast and Central-West regions. It has a generalist feeding habit, an

9. Mitochondrial control region haplotypes of the South American sea lion Otaria flavescens (Shaw, 1800)
The South American sea lion, Otaria flavescens, is widely distributed along the Pacific and Atlantic coasts of South America. However, along the Brazilian coast, there are only two nonbreeding sites for the species (Refúgio de Vida Silvestre da Ilha dos Lobos and Refúgio de Vida Silvestre do Molhe Leste da Barra do Rio Grande), both in Southern Brazil.

10. Theoretical paths for the literary reading of subaltern resistance practices. / Caminhos teóricos para a leitura literária de práticas de resistência subalterna.
By recognizing that the voices of subaltern characters were often overlooked in the study of literary texts, we decided to carry out a theoretical work that could assist the student of literature to structure his/her literary analysis by following a decolonized perspective. We wanted the scholar of literature to transcend the focus on the characterization of

12. Karyotype differentiation of four Cestrum species (Solanaceae) revealed by fluorescent chromosome banding and FISH
The karyotypes of four South American species of Cestrum (C. capsulare, C. corymbosum, C. laevigatum and C. megalophylum) were studied using conventional staining, C-CMA/DAPI chromosome banding and FISH with 45S and 5S rDNA probes. The karyotypes showed a chromosome number of 2n = 2x = 16, with metacentric chromosomes, except for the eighth submeta- to acroc
