PERCEPÇÃO DO PROFESSOR DE GEOGRAFIA SOBRE O ENSINO DA GEOMORFOLOGIA NA EDUCAÇÃO BÁSICA: UM ESTUDO NAS ESCOLAS PÚBLICAS DE BOA VISTA – RORAIMA

O estudo objetiva analisar a percepção do professor de Geografia sobre a Geomorfologia na Educação Básica, em três escolas públicas localizadas no centro e na zona norte da cidade de Boa Vista/Roraima. A metodologia caracterizou-se por ser exploratória e descritiva, foi realizada investigação in loco através de entrevista estruturada. Os resultados demonstraram que os professores sentem dificuldades em ministrar conteúdos de Geomorfologia, principalmente pela falta de formação continuada

Dificuldades Enfrentadas Pelos Indígenas Durante A Permanência Em Uma Casa De Saúde Indígena Na Região Amazônica/brasil

The National Policy of Health Care to the Indigenous Peoples (PNASI) was established by the Ministry of Health restructuring the Primary Care to Indigenous Health, following the principles and guidelines from the Unified Health System (SUS). This study aims to identify the difficulties faced by the indigenous peoples during the stay in the Indigenous Health Center (Casai) in Santarém (PA), in the Amazon region. It is an exploratory qualitative study, whose approach was through semi-structured interviews, recorded and transcribed, with 15 indigenous people from five ethnic groups, assisted by the Casai (Mawayana, Tunayana, Wai-wai, Tiriyó and Katwena), with help from a translator acquainted with the dialects. We used the content analysis arising from thematic categories: the difficulties faced during the adaptation period in the Casai/Santarém, the feeling about leaving the indigenous land and the perspectives regarding the improvements during the stay. We consider that, despite the increasing changes and advances in indigenous health in Brazil, improvements that can truly meet the health peculiarities of each ethnic group are necessary. © 2016, UNIV SAOPAULO.

Poisoning by Poiretia punctata in cattle and sheep

Poiretia punctata (Willd.) Desv. was associated with cattle and sheep poisoning on nine farms in the State of Sergipe, northeastern Brazil. The animals were found dead or died later after showing clinical signs for up to 18 hours. Two sheep that ingested 40g/kg body weight (g/kg) of fresh P. punctata died three and eight hours after ingestion, respectively. Another sheep that ingested 40g/kg five days after plant collection showed mild clinical signs and recovered after 24 hours. Two sheep that received 20g/kg and another that ingested three daily doses of 20g/kg showed clinical signs, but recovered. Two cattle that ingested 20g/kg of the fresh plant exhibited clinical signs and recovered. The clinical observations of poisoning were depression, ataxia, loss of equilibrium, broad-based stance, head down, falls, mandibular trismus, opisthotonous, nystagmus, and recumbence. Significant gross and histologic lesions were not observed. Samples of P. punctata were analyzed for nitrates, cyanogenic glycosides, and sodium monofluouracetate with negative results. It is concluded that P. punctata is a toxic plant that caused death in cattle and sheep in the State of Sergipe

Classification of antimicrobial resistance using artificial neural networks and the relationship of 38 genes associated with the virulence of Escherichia coli isolates from broilers

Avian pathogenic Escherichia coli (APEC) is responsible for various pathological processes in birds and is considered as one of the principal causes of morbidity and mortality, associated with economic losses to the poultry industry. The objective of this study was to demonstrate that it is possible to predict antimicrobial resistance of 256 samples (APEC) using 38 different genes responsible for virulence factors, through a computer program of artificial neural networks (ANNs). A second target was to find the relationship between (PI) pathogenicity index and resistance to 14 antibiotics by statistical analysis. The results showed that the RNAs were able to make the correct classification of the behavior of APEC samples with a range from 74.22 to 98.44%, and make it possible to predict antimicrobial resistance. The statistical analysis to assess the relationship between the pathogenic index (PI) and resistance against 14 antibiotics showed that these variables are independent, i.e. peaks in PI can happen without changing the antimicrobial resistance, or the opposite, changing the antimicrobial resistance without a change in PI

X chromosome inactivation does not necessarily determine the severity of the phenotype in Rett syndrome patients

Rett syndrome (RTT) is a severe neurological disorder usually caused by mutations in the MECP2 gene. Since the MECP2 gene is located on the X chromosome, X chromosome inactivation (XCI) could play a role in the wide range of phenotypic variation of RTT patients; however, classical methylation-based protocols to evaluate XCI could not determine whether the preferentially inactivated X chromosome carried the mutant or the wild-type allele. Therefore, we developed an allele-specific methylation-based assay to evaluate methylation at the loci of several recurrent MECP2 mutations. We analyzed the XCI patterns in the blood of 174 RTT patients, but we did not find a clear correlation between XCI and the clinical presentation. We also compared XCI in blood and brain cortex samples of two patients and found differences between XCI patterns in these tissues. However, RTT mainly being a neurological disease complicates the establishment of a correlation between the XCI in blood and the clinical presentation of the patients. Furthermore, we analyzed MECP2 transcript levels and found differences from the expected levels according to XCI. Many factors other than XCI could affect the RTT phenotype, which in combination could influence the clinical presentation of RTT patients to a greater extent than slight variations in the XCI pattern
