Description of Rhodnius marabaensis sp. n. (Hemiptera, Reduviidae, Triatominae) from Pará state, Brazil
No full textRhodnius marabaensis sp. n. was collected on 12 May 2014 in the Murumurú Environmental Reserve in the city of Marabá, Pará State, Brazil. This study was based on previous consultation of morphological descriptions of 19 Rhodnius species and compared to the identification key for the genus Rhodnius. The examination included specimens from 18 Rhodnius species held in the Brazilian National and International Triatomine Taxonomy Reference Laboratory in the Oswaldo Cruz Institute in Rio de Janeiro, Brazil. The morphological characteristics of the head, thorax, abdomen, genitalia, and eggs have been determined. Rhodnius prolixus and R. robustus were examined in more detail because the BLAST analysis of a cyt-b sequence shows they are closely related to the new species, which also occurs in the northern region of Brazil. The most notable morphological features that distinguish R. marabaensis sp. n. are the keel-shaped apex of the head, the length of the second segment of the antennae, the shapes of the prosternum, mesosternum and metasternum, the set of spots on the abdomen, the male genitalia, the posterior and ventral surfaces of the external female genitalia, and the morphological characteristics of the eggs. Rhodnius jacundaensis Serra, Serra & Von Atzingen (1980) nomen nudum specimens deposited at the Maraba Cultural Center Foundation - MCCF were examined and considered as a synonym of R. marabaensis sp. n.6214562CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informaçãoSem informação2010/15386-
Study of risk factors for atopic sensitization, asthma, and bronchial hyperresponsiveness in animal laboratory workers
No full textThe aim of this estudy was to investigate the influence of allergen exposure levels and other risk factors for allergic sensitization, asthma, and bronchial hyperresponsiveness (BHR) in workers exposed to laboratory animals. This was a cross-sectional study performed at two universities, 123 workplaces with 737 subjects. Dust samples were collected from laboratories and animal facilities housing rats, mice, guinea pigs, rabbits, or hamsters and analyzed by enzyme-linked immunosorbent assay (ELISA) to measure allergen concentrations. We also sampled workplaces without animals. Asthma was defined by both symptoms and BHR to mannitol. The concentrations of allergens were tested for association with a skin prick test, respiratory symptoms, spirometry data, and BHR. This multivariate analysis was performed by using Poisson regression to estimate the relative risk (RR) for the exposed group. Our sample comprised students and workers, with 336 subjects in the nonexposed group and 401 subjects in the exposed group. Sixty-nine subjects (17%) had positive results in the skin prick test for animal allergens in the exposed group; in the nonexposed group, 10 subjects had positive results (3%) (p<0.001). Exposure to laboratory animals over 2.8 years was associated with atopic sensitization (RR=1.85; 95% confidence interval: 1.09–3.15; p=0.02). Allergen concentration was not associated with sensitization, asthma, or BHR. Exposure to laboratory animals was associated with atopic sensitization. However, we did not find a cutoff allergen concentration that increased the risk for sensitization. Duration of exposure seems to be more relevant to sensitization than concentration of allergens in dust.581715CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informaçãoSem informaçã
Hip-hop and the reconfiguration of blackness in São Paulo: the influence of african american political and musical movements in the twentieth century
No full textHip-hop arrived in São Paulo, Brazil in the late 1970s. During this time, African Brazilians organized meetings known as ‘Black parties.’ At Black parties, people listened to music, danced and shared Black experiences. The Black parties were greatly influenced by African-American music such as soul, funk and jazz, and contemporary socio-political movements like Civil Rights and the Black Panther Party. African Brazilians disseminated images and symbols about blackness and called for Black pride. Phrases like James Brown's ‘Say It Loud: I'm Black and I'm Proud' were widespread. Today, hip-hop is recognized as an important influence in African-Brazilian history. The cultural exchange between Black youth in São Paulo and New York contributed to the reconfiguration of the Black movement in Brazil and was the vehicle by which African Brazilians acquired knowledge of the African diaspora. This essay will present three important arguments for understanding how hip-hop became a great political movement among Black youth in Brazil. My first argument is that African-American culture has provided a political language to what Paul Gilroy calls the ‘Black universe.’ This was accomplished through the public circulation of images and symbols about Black struggle. Secondly, São Paulo and New York, though structurally different, have similar histories in the areas of urban planning and population growth, and hip-hop had a comparable effect on marginalized communities in both cities. Finally, the cultural exchange between Black youth of São Paulo and New York helped change the Black movement and identity in São Paulo.22216017
