A new species of Pseudopaludicola Miranda-Ribeiro, 1926 (Anura: Leiuperidae) from the state of Mato Grosso, Brazil, with comments on the geographic distribution of Pseudopaludicola canga Giaretta & Kokubum, 2003.

A new species of Pseudopaludicola is described from the state of Mato Grosso, western Brazil. The new species inhabits the transition zone between Brazilian Cerrado and Amazon rainforest in northern Mato Grosso, and is characterized by its medium size (snout-vent length 12-17 mm), lack of T-shaped terminal phalanges, toe tips not expanded laterally, presence of two antebrachial tubercles, and smooth upper eyelids. The advertisement call of the new species consists of a series composed of 11-74 non-pulsed notes. Mean dominant frequency is 3938 Hz. Each note presents a slight ascendant frequency modulation in its first half, and another ascendant modulation in its last half. We also present new data on the distribution and conservation status of Pseudopaludicola canga.

Abnormal evening vertical plasma drift and effects on ESF and EIA over Brazil-South Atlantic sector during the 30 October 2003 superstorm

Equatorial F region vertical plasma drifts, spread F and anomaly responses, in the south American longitude sector during the superstorm of 30 October 2003, are analyzed using data from an array of instruments consisting of Digisondes, a VHF radar, GPS TEC and scintillation receivers in Brazil, and a Digisonde and a magnetometer in Jicamarca, Peru. Prompt penetrating eastward electric field of abnormally large intensity drove the F layer plasma up at a velocity ∼1200 ms -1 during post dusk hours in the eastern sector over Brazil. The equatorial anomaly was intensified and expanded poleward while the development of spread F/plasma bubble irregularities and GPS signal scintillations were weaker than their quiet time intensity. Significantly weaker F region response over Jicamarca presented a striking difference in the intensity of prompt penetration electric field between Peru and eastern longitudes of Brazil. The enhanced post dusk sector vertical drift over Brazil is attributed to electro-dynamics effects arising energetic particle precipitation in the South Atlantic Magnetic Anomaly (SAMA). These extraordinary results and their longitudinal differences are presented and discussed in this paper. Copyright 2008 by the American Geophysical Union.

Circulation of Different Lineages of Dengue Virus 2, Genotype American/Asian in Brazil: Dynamics and Molecular and Phylogenetic Characterization

The American/Asian genotype of Dengue virus type 2 (DENV-2) was introduced into the Americas in the 80′s. Although there is no data showing when this genotype was first introduced into Brazil, it was first detected in Brazil in 1990. After which the virus spread throughout the country and major epidemics occurred in 1998, 2007/08 and 2010. In this study we sequenced 12 DENV-2 genomes obtained from serum samples of patients with dengue fever residing in São José do Rio Preto, São Paulo (SJRP/SP), Brazil, in 2008. The whole open reading frame or envelope sequences were used to perform phylogenetic, phylogeographic and evolutionary analyses. Isolates from SJRP/SP were grouped within one lineage (BR3) close to isolates from Rio de Janeiro, Brazil. Isolates from SJRP were probably introduced there at least in 2007, prior to its detection in the 2008 outbreak. DENV-2 circulation in Brazil is characterized by the introduction, displacement and circulation of three well-defined lineages in different times, most probably from the Caribbean. Thirty-seven unique amino acid substitutions were observed among the lineages, including seven amino acid differences in domains I to III of the envelope protein. Moreover, we dated here, for the first time, the introduction of American/Asian genotype into Brazil (lineage BR1) to 1988/89, followed by the introduction of lineages BR2 (1998-2000) and BR3 (2003-05). Our results show a delay between the introduction and detection of DENV-2 lineages in Brazil, reinforcing the importance and need for surveillance programs to detect and trace the evolution of these viruses. Additionally, Brazilian DENV-2 differed in genetic diversity, date of introduction and geographic origin and distribution in Brazil, and these are important factors for the evolution, dynamics and control of dengue. © 2013 Drumond et al.

Occupational mobility and income differentials: The experience of Brazil between 2002 and 2010

Since the start of the twenty-first century, the Brazilian economy has experienced a growth cycle with characteristics unlike those of its previous historical experience, combining growth, macroeconomic stability and distributive progress. In this context, the study aims to analyse the factors and distributive effects of occupational mobility in Brazil, based on data obtained from the Monthly Employment Survey. The results suggest that: (i) mobility has been used in Brazil as a way to raise wages, even when it involves a drop in socio-occupational status; (ii) nonetheless, the wage increase obtained by changing job or occupational segment is smaller for poorer workers than for wealthier ones; and (iii) consequently, mobility helps to increase income, but it also tends to widen wage gaps.

Epidemiological aspects of retrovirus (HTLV) infection among Indian populations in the Amazon Region of Brazil

O HTLV foi descrito inicialmente associado a uma leucemia no Japão e a uma doença neurológica presente no Caribe. Logo foi evidenciado que o HTLV-II era endêmico entre Ameríndios e, particularmente, entre Índios brasileiros. A Amazônia brasileira é a maior área endêmica para o vírus e dessa forma, permitiu que fossem realizados vários estudos relacionados com a sua biologia, a busca de doença, informações epidemiológicas que incluíram uma bem definida distribuição geográfica, a definição dos modos de transmissão e manutenção do vírus em comunidades pequenas, epidemiologicamente fechadas, assim como contribuições para o diagnóstico laboratorial da infecção. Um novo subtipo molecular, denominado HTLV-IIc, foi adicionalmente descrito baseando-se no sequenciamento genético do vírus e na análise filogenética. Esse subtipo está presente em outras áreas do país, indicando que o HTLV também funciona como um marcador precioso das migrações humanas nas Américas no passado e um provável marcador dos costumes das populações atuais. O outro retrovírus humano, o HIV, ainda não é prevalente nas comunidades indígenas, apesar de que elas podem ser facilmente alcançadas em virtude das inúmeras facilidades de transmissão para o vírus.

Relações raciais: a pesquisa na pós-graduação em educação no Brasil (2005 – 2010)

A educação é o processo de inserção de homens e mulheres no mundo cultural. E a educação, dentro das sociedades mais complexas como as capitalistas industriais, é uma atividade planejada, que implica a elaboração de objetivos e a indicação de meios para atingi-los. A compreensão das tramas de construção de práticas formalizadas é ligada a agentes que determinam os objetivos da educação e suas intenções educativas sobre Relações Raciais no Brasil. Dediquei-me às atividades de levantamento acadêmico sobre a produção de teses de doutoramento, concluídas entre os anos 2005-2010, e a respeito de pesquisas e estudos sobre Educação e Relações Raciais nos Programas de Pós-Graduação em Educação. Investiguei sobre a circulação da temática relações raciais em espaços de elaboração de políticas educacionais, especificamente programas do Governo Federal que atendam à demanda de inclusão da temática no sistema de ensino no Brasil. Pois, a partir de 2003, a temática passa por uma fase de institucionalização, principalmente pelo conjunto jurídico que estabelece novo marco legal à educação. O objeto pesquisado incluiu a configuração de práticas formalizadas que desenvolvem quadros de agentes especializados sobre relações raciais. Analisar a relação intencional entre as práticas formalizadas sobre relações raciais que prescrevem a formulação de objetivos educacionais nos diferentes níveis e instâncias sociais. Identificar os objetivos do sistema de ensino descritos nos programas do Governo Federal destinados à promoção da educação para igualdade racial. Relacionar as práticas formalizadas no campo da pesquisa em educação às intenções descritas nos programas do Governo Federal. Explicar quais os interesses que movem essas práticas formalizadas a partir das demandas educacionais da temática relações raciais. A escrita da tese pauta-se na defesa de análise em que a obrigatoriedade da temática relações raciais é movida por duas forças antagônicas, uma direcionada à constituição de direito à cidadania movida por intenções de construir uma sociedade para a igualdade racial, de oportunidades de acesso a bens materiais e simbólicos e livre de práticas discriminatórias; outra relacionada aos interesses existentes dentro de um jogo de poder a ponto de converter a educação no centro de tão acerba disputa que desfavorece dissimuladamente a equidade racial no Brasil.

Evaluation of cases of pemphigus vulgaris and pemphigus foliaceus from a reference service in Pará state, Brazil

BACKGROUND: Pemphigusis a bullous, rare and chronic autoimmune disease. There are two major forms of pemphigus: vulgaris and foliaceus. Epidemiological data and clinical outcome in patients diagnosed in the Brazilian Amazon states are still rare. OBJECTIVES: To study the occurrence of the disease during the study period and analyze the epidemiological profile of patients, the most common subtype of pemphigus, and the clinical evolution of patients. METHODS: Retrospective analysis of medical records of hospitalized patients with pemphigus foliaceus and pemphigus vulgaris in the period from 2003 to 2010 in Dermatology Service of Hospital Fundação Santa Casa de Misericórdia do Pará, Belém, Northern Brazil. RESULTS: We found a total of 20 cases of pemphigus during the study period, 8 of which were of foliaceus pemphigus and 12 of vulgaris pemphigus. Pemphigus foliaceus had the predominance of male patients (75%), showed satisfactory clinical evolution, and was characterized by absence of pediatric cases. Pemphigus vulgaris affected more women (66.7%), showed mean hospital stay of 1 to 3 months (50%), and there were three cases of death (25%). The prescribed immunosuppressive drugs included prednisone with or without combination of azathioprine and/or dapsone. Sepsis was associated with 100% of the deaths. CONCLUSIONS: The occurrence of the disease is rare, there are no familiar/endemic outbreaks in the sample. Evolution is usually favorable, but secondary infection is associated with worse prognosis. The choice of best drugs to treat pemphigus remains controversial.

Temporal, diel and spatial variability of decapod larvae from St Paul`s Rocks, an equatorial oceanic island of Brazil

Temporal, spatial and diel variation in the distribution and abundance of organisms is an inherent property of ecological systems. The present study describes these variations and the composition of decapod larvae from the surface waters of St Paul`s Rocks. The expeditions to the archipelago were carried out in April, August and November 2003, March 2004 and May 2005. Surface plankton samples were collected during the morning and dusk periods, inside the inlet and in increasing distances around the archipelago (similar to 150, 700 and 1500 m). The identification resulted in 51 taxa. Seven species, six genera and larvae of the families Pandalidae and Portunidae were identified for the first time in the area. The mean larval density varied from zero to 150.2 +/- 69.6 individuals 100 m(-3) in the waters surrounding the archipelago and from 1.7 +/- 3.0 to 12,827 +/- 15,073 individuals 100 m(-3) inside the inlet. Significant differences on larval density were verified between months and period of the day, but not among the three sites around the archipelago. Cluster and non-metric multidimensional scaling analysis indicated that the decapod larvae community was divided into benthic and pelagic assemblages. Indicator species analysis (ISA) showed that six Brachyura taxa were good indicators for the inlet, while three sergestids were the main species from the waters around the archipelago. These results suggest that St Paul`s Rocks can be divided into two habitats, based on larval composition, density and diversity values: the inlet and the waters surrounding the archipelago.
