A roupa nova do presidente: a politização da imagem pública de Jânio Quadros (1947-1961)

Jânio Quadros public image is often considered deprived of any political meaning either by historians or by collective memory. In most cases he is treated as a demagogue who promoted himself only through his personalism, which could be seen in his public appearances unkempt and with open-necked shirts. Such perspective is deeply related to the way his opponents and enemies represented him in the political debates, and its core has been successful in penetrating the historiography. However in this text I intend to suggest that Jânio's images conveyed an array of political senses during the 1950s and early 1960s, since the beginning of his career till when he disputed presidential elections and ruled Brazil as president. Through his gestures and clothes, among which his Indian slacks deserve more attention, he tried to express his project related to the Christian Democracy and the Independent Foreign Policy. To deal with such hypothesis, the main sources will be the magazines O Cruzeiro and Manchete and others photos and drawings that were considerably widespread at that time.A imagem pública de Jânio Quadros é frequentemente considerada como desprovida de quaisquer significados políticos, seja por historiadores ou pela memória coletiva. Na maioria dos casos, ele é tratado como um demagogo que se promovia apenas através de seu personalismo, exibindo-se em suas aparições públicas despenteado e com camisas abertas no colarinho. Tal perspectiva está profundamente relacionada com a forma pela qual seus oponentes e inimigos o representavam nos debates políticos, e em seu cerne foi bem-sucedida, tendo penetrado na historiografia. Neste texto, porém, pretendo sugerir que, perpassando a década de 1950 e o início da de 1960, desde o início de sua carreira até o momento em que disputou eleições presidenciais e foi o presidente do Brasil, as imagens de Jânio veiculavam um amplo leque de sentidos políticos. Por meio de gestos e roupas, destacando-se aí seus slacks indianos, ele procurou expressar seus projetos relacionados à Democracia Cristã e à Política Externa Independente. Para lidar com essa hipótese, as principais fontes fotográficas e textuais elencadas são as revistas O Cruzeiro e Manchete da época, e outras fotos e ilustrações que então foram bastante difundidas

ATLANTIC-CAMTRAPS: a dataset of medium and large terrestrial mammal communities in the Atlantic Forest of South America

Our understanding of mammal ecology has always been hindered by the difficulties of observing species in closed tropical forests. Camera trapping has become a major advance for monitoring terrestrial mammals in biodiversity rich ecosystems. Here we compiled one of the largest datasets of inventories of terrestrial mammal communities for the Neotropical region based on camera trapping studies. The dataset comprises 170 surveys of medium to large terrestrial mammals using camera traps conducted in 144 areas by 74 studies, covering six vegetation types of tropical and subtropical Atlantic Forest of South America (Brazil and Argentina), and present data on species composition and richness. The complete dataset comprises 53,438 independent records of 83 species of mammals, includes 10 species of marsupials, 15 rodents, 20 carnivores, eight ungulates and six armadillos. Species richness averaged 13 species (±6.07 SD) per site. Only six species occurred in more than 50% of the sites: the domestic dog Canis familiaris, crab-eating fox Cerdocyon thous, tayra Eira barbara, south American coati Nasua nasua, crab-eating raccoon Procyon cancrivorus and the nine-banded armadillo Dasypus novemcinctus. The information contained in this dataset can be used to understand macroecological patterns of biodiversity, community, and population structure, but also to evaluate the ecological consequences of fragmentation, defaunation, and trophic interactions. © 2017 by the Ecological Society of Americ

The Genome of Anopheles darlingi, the main neotropical malaria vector

Anopheles darlingi is the principal neotropical malaria vector, responsible for more than a million cases of malaria per year on the American continent. Anopheles darlingi diverged from the African and Asian malaria vectors ∼100 million years ago (mya) and successfully adapted to the New World environment. Here we present an annotated reference A. darlingi genome, sequenced from a wild population of males and females collected in the Brazilian Amazon. A total of 10 481 predicted protein-coding genes were annotated, 72% of which have their closest counterpart in Anopheles gambiae and 21% have highest similarity with other mosquito species. In spite of a long period of divergent evolution, conserved gene synteny was observed between A. darlingi and A. gambiae. More than 10 million single nucleotide polymorphisms and short indels with potential use as genetic markers were identified. Transposable elements correspond to 2.3% of the A. darlingi genome. Genes associated with hematophagy, immunity and insecticide resistance, directly involved in vectorhuman and vectorparasite interactions, were identified and discussed. This study represents the first effort to sequence the genome of a neotropical malaria vector, and opens a new window through which we can contemplate the evolutionary history of anopheline mosquitoes. It also provides valuable information that may lead to novel strategies to reduce malaria transmission on the South American continent.

Association between Childhood Dental Experiences and Dental Fear among Dental, Psychology and Mathematics Undergraduates in Brazil

The aim of the present study was to evaluate the association between childhood dental experiences and dental fear in adulthood among dentistry, psychology and mathematics undergraduate students. A cross-sectional study of 1,256 students from the city of Belo Horizonte, Brazil, was performed. Students responded to the Brazilian version of the Dental Fear Survey (DFS) and a questionnaire regarding previous dental experiences. Both the DFS and the questionnaire were self-administered. Association was tested using descriptive, bivariate and multivariate linear regression analysis, with a 5% significance level. Dentistry undergraduates reported lower scores than psychology (p < 0.001) and mathematics undergraduates (p < 0.05) for all three dimensions of the DFS. Negative dental experiences in childhood was associated with dimensions of Avoidance (B = 2.70, p < 0.001), Physiological arousal (B = 1.42, p < 0.001) and Fears of specific stimuli/situations (B = 3.44, p < 0.001). The reason for first visit to dentist was associated with dimensions of Physiological arousal (B = 0.76, p < 0.01) and Fears of specific stimuli/situations (B = 1.29, p < 0.01). Dentists should be encouraged to evaluate the dental fear of their patients before treatment. The DFS has been found to be an effective instrument for this purpose

Oxidative metabolism and muscle biochemical profile of polo horses supplemented with an ADE vitamin complex

Horses used for the game of polo experience abrupt and frequent changes in exercise intensity. To meet this variable energy demand, the horses use both aerobic and anaerobic pathways in varying proportions and intensities. In this context, there must be a balance between the formation of reactive oxygen species (ROS) and the action of antioxidants to prevent oxidative stress and its consequences. The effect of supplementation with an ADE vitamin complex on oxidative metabolism was evaluated in 18 crossbred horses randomly divided between a treated group (TG) and a control group (CG). The TG animals received the ADE vitamin complex (1mL/50 kg of body weight) by deep intramuscular injection at 30 and 15 days before the game. The CG horses received 10ml of saline by the same administration route and schedule. During the polo match, the animals played for a total of 7.5 min. Blood samples were collected on the same days as the treatments were administered, and immediately before and at 15, 90 and 180 minutes after the game. The concentrations of creatine phosphokinase (CK), lactate dehydrogenase (LDH), lactate, glucose, aspartate aminotransferase (AST), glutathione (GSH), superoxide dismutase (SOD) and malondialdehyde (MDA) were measured in the blood samples. After the game, the TG demonstrated higher levels of AST, lactate and glucose than the CG, suggesting more efficient energy use by the treated animals. The higher GSH and lower lactate levels in the TG before the game suggest the presence of a greater antioxidant supply in the treated animals. The maintenance of the MDA levels indicates that neither of the groups exhibited oxidative stress
