1. A multivariate approach to differentiate yerba mate (Ilex paraguariensis) commercialized in the southern Brazil on the basis of phenolics, methylxanthines and in vitro antioxidant activity
Abstract The consumption of yerba mate beverages is related to several health benefits. These desirable properties are mainly due to the bioactive compounds. However, the levels of those compounds are directly affected by factors such as geographical origin. This study aimed to use chemometrics to evaluate the antioxidant compounds of yerba mate (consumed as

2. Schistosomiasis in the Middle Paranapanema river region, state of São Paulo, Brazil: Does it matter today for public health?
Abstract INTRODUCTION: The Middle Paranapanema watershed is known for the transmission of schistosomiasis, and there have been autochthonous cases since 1952. This study aimed to describe this disease in space and time and evaluate its current importance as a public health problem. METHODS: Thematic maps showing the risk areas for transmission of schisto

3. Arranjos regionais de governança do Sistema Único de Saúde: diversidade de prestadores e desigualdade espacial na provisão de serviços
O estudo analisa os arranjos regionais de governança do Sistema Único de Saúde (SUS), segundo esfera jurídica dos prestadores e distribuição espacial da produção de serviços de média e alta complexidade no Brasil. Tais arranjos expressam o modo como a reforma do Estado e do sistema de saúde promoveram a redistribuição de funções entre entes go

4. Distribution of rainfall probability in the Tapajos River Basin, Amazonia, Brazil
Resumo Estudos sobre a probabilidade de chuvas e suas variações espaço-temporais são importantes para o planejamento de recursos hídricos e otimização do calendário de atividades agrícolas. O presente estudo identifica a ocorrência de chuvas pela cadeia de Markov de primeira ordem (CM) e por dois estados da bacia hidrográfica do rio Tapajós (BHRT

5. Novel molecular evidence of population structure in Anopheles (Kerteszia) bellator from Brazilian Atlantic Forest
Anopheles bellator is a primary malaria vector in the Atlantic Forest. Partial sequences of timeless and Clock genes were used to assess the genetic differentiation of five Brazilian populations, which showed strong population structure (e.g. high F ST values and fixed differences) in all pairwise comparisons between Bahia sample and the others from Paraná

6. Serotyping and Genotyping of Salmonella Strains Isolated From Broilers, Chicken Carcasses Before and After Chilling, and Frozen Chicken Breasts Produced in The States of Mato Grosso do Sul and Santa Catarina, Brazil
ABSTRACT The present study investigated the effectiveness of a single Salmonella prevention and control program applied in two different processing plants, located in the states of Mato Grosso do Sul (plant A) and Santa Catarina (Plant B), belonging to the same company, and identified Salmonella strain subtypes isolated from broilers, carcasses before and af

7. Does Size Matter? Electoral Performance of Small Parties in Brazil
What is the impact of small parties on electoral outcomes? This articles aims at contributing to the literature on party systems by proposing a new method to classify political parties. The methodology is applied to Brazil by focusing on the description of the election results of small parties. Cluster analysis is employed to classify political party size ba

8. Reaction of sources of resistance to white mold to microsatellite haplotypes of Sclerotinia sclerotiorum
ABSTRACT White mold caused by the fungus Sclerotinia sclerotiorum is the most yield-limiting disease of common bean in Brazil. To date, there has been no commercial cultivar resistant to this disease. In a greenhouse we evaluated white mold resistance sources (Cornell 605, A195 and G122) against eight isolates of S. sclerotiorum from five Brazilian states. A

9. The Institutional Presidency from a Comparative Perspective: Argentina and Brazil since the 1980s
This paper focuses on the evolution of the institutional presidency – meaning the cluster of agencies that directly support the chief of the executive – in Argentina and Brazil since their redemocratization in the 1980s. It investigates what explains the changes that have come about regarding the size of the institutional presidency and the types of agen

10. El Pensamiento Probabilístico de los Profesores de Biología en Formación
Prospective secondary teachers need training in accordance with the demands of the 21st century. This requires the development of a thought that allows interpreting and addressing the phenomena of random nature. The aim of this work is to determine trends of probabilistic thinking of biology teachers in training from the province of Mendoza, Argentina. We ap

11. Genetic diversity and structure of Atta robusta (Hymenoptera, Formicidae, Attini), an endangered species endemic to the restinga ecoregion
The genetic diversity and structure of the ant Atta robusta were assessed by ISSR (inter-simple sequence repeats) in 72 colonies collected from 10 localities in the Brazilian states of Espírito Santo (48 colonies) and Rio de Janeiro (24 colonies). The ISSR pattern included 67 bands, 51 of them (76.1%) polymorphic. Analysis of molecular variance (AMOVA) reve

12. Morphological and molecular characterization of Fusarium. solani and F. oxysporum associated with crown disease of oil palm
Crown disease (CD) is infecting oil palm in the early stages of the crop development. Previous studies showed that Fusarium species were commonly associated with CD. However, the identity of the species has not been resolved. This study was carried out to identify and characterize through morphological approaches and to determine the genetic diversity of the
