Resumo As análises da dinâmica de alteração nos padrões de uso e ocupação do solo, que são importantes no planejamento de áreas urbanas, podem ser realizadas de forma indireta por meio de imagens orbitais de sensoriamento remoto. As imagens orbitais têm se revelado importantes ferramentas para medir e monitorar as atividades humanas na Terra. Desse modo, este artigo tem como objetivo mapear as áreas de entorno do Passeio das Águas Shopping, situado na região norte de Goiânia, GO, atribuindo a ele a condição de polo gerador de viagens (PVG). Assim, foi avaliada a dinâmica de alteração de uso e cobertura do solo em seu entorno. A metodologia empregada teve como base o processamento digital de imagens orbitais em ambiente de sistema de informação geográfica (SIG). Os resultados revelaram que, em um intervalo de 10 anos, houve redução da área de vegetação e aumento significativo das áreas pavimentada e construída, a ponto de promover mudanças significativas no padrão de uso do solo após a implementação do PGV. Abstract The analysis of the dynamics of changes in patterns of land use and occupation, which is essential for the planning of urban areas, can be done indirectly through remote sensing orbital images. Orbital images have proven to be important tools for measuring and monitoring human activities on Earth. Thus, this paper aims to map the surrounding areas of Passeio das Águas Shopping Center, located in the northern region of Goiânia, Brazil, assigning to it the condition of Travel Generator (TG). Hence, this study analysed the dynamics of change in land use and cover in its surroundings. The methodology used was based on the digital processing of orbital images in a Geographic Information System (GIS) environment. The results showed that, in a 10-year interval, there was a reduction of the vegetation area, and a significant increase in the paved and built areas, promoting significant changes in the land use pattern after the implementation of the TG.

The spermatic membrane is rich in polyunsaturated fatty acids, which makes it sensitive to the action of reative species of oxygen, which can damage the seminal quality of the scraps. The purpose of this study was to evaluate the effect of the supplementation of two selenium sources at different doses. Third five scraps were allocated in four groups: (INOR30) 0.30 ppm sodium selenite; (COMP30) 0.30 ppm selenium metal-amino acid; (MIXED15+15) 0.15 ppm sodium selenite + 0.15 ppm selenium metal-amino acid and (COMP15) 0.15 ppm selenium metal-amino acid. The ejaculates of the scraps were evaluated over 22 weeks, resulting in 210 samples evaluated for volume, motility, pH, presence of agglutination and morphological changes, and 140 samples for spermatic concentration. The data was analyzed with repeated measures in time in a mixed model with type of selenium supplementation, periods of evaluation (one period of two weeks + five periods of four weeks) and their interactions as fixed effects, and animal and the worker that collected the ejaculates as random effects. Results showed no difference in selenium supplementation with the sources and doses used. In this way, it was possible to verify that the metal amino acid of selenium at the dose of 0.15 ppm promotes the same effect as the diets formulated with 0.30 ppm of sodium selenite.

Resumo A membrana espermática é rica em ácidos graxos poliinsaturados, o que a torna sensível à ação de espécies reativas de oxigênio, que podem prejudicar a qualidade seminal dos cachaços. O objetivo do presente estudo foi avaliar o efeito da suplementação de duas fontes de selênio em diferentes doses. Trinta e cinco cachaços foram distribuídos em quatro grupos: (INOR30) 0,30 ppm de selenito de sódio; (COMP30) 0,30 ppm de metal-aminoácido de selênio; (MISTO15+15) 0,15 ppm de selenito de sódio + 0,15 ppm de metal-aminoácido de selênio e (COMP15) 0,15 ppm de metal-aminoácido de selênio. Os ejaculados dos cachaços foram avaliados durante 22 semanas, resultando em 210 amostras avaliadas para volume, motilidade, pH, presença de aglutinação e alterações morfológicas, e 140 amostras para concentração espermática. Os dados foram analisados com medidas repetidas no tempo em modelo misto, em que o tipo de suplementação de selênio, os períodos de avaliação (um período de duas semanas + cinco períodos de quatro semanas) e suas interações foram os efeitos fixos, e o animal e o funcionário que coletou os ejaculados foram os efeitos aleatórios. Os resultados obtidos demonstraram não haver diferença na suplementação de selênio com as fontes e doses utilizadas. Com isso, foi possível verificar que o metal-aminoácido de selênio na dose de 0,15 ppm promove o mesmo efeito das dietas formuladas com 0,30 ppm de selenito de sódio.

Brazil is a country with a high prevalence of infectious diseases such as leprosy and leishmaniasis. However, coinfection of these diseases is still poorly understood. We report a case of a patient who presented with lepromatous leprosy and cutaneous-mucosal leishmaniasis at the same period. After clinical, laboratory, and histopathological diagnosis, the treatment was introduced and the patient showed important clinical improvement. He was followed in our outpatient clinic. Both pathologies play an important role in the immune system. Depending on the immune response profile of the host, diseases may present themselves in different ways. In this case, the patient showed a divergent immune response for each disease. We hypothesized that this response is specific for each pathogen.

The objective of this article was to investigate the perception of esthetic changes in the facial profile of bilateral Class II patients treated with the Modified Thurow Appliance for extraoral treatment. Silhouettes were traced of profiles of patients who initially presented a bilateral Class II molar relationship and who, post-treatment, presented molars in a Class I relationship. Three groups were formed: the first composed of patients with maxillary protrusion (SNA >84°), the second with maxillary retrusion (SNA

Este trabalho objetivou avaliar a "performance" de quatro clones híbridos de Eucalyptus spp., propagados pelas técnicas de estaquia, micropropagação, microestaquia e miniestaquia, quanto às características de crescimento em altura e diâmetro (dap), bem como a produção de biomassa da parte aérea, em teste clonal, instalado em dois locais distintos localizados no norte de Minas Gerais. De acordo com os resultados, pode-se concluir que os efeitos das técnicas de propagação não resultaram em diferenças expressivas no crescimento em altura e dap, nas avaliações aos 4, 8, 16 e 24 meses de idade, dos clones estudados. Em relação à biomassa da parte aérea, os resultados não indicaram uma tendência sobre possíveis efeitos das técnicas de propagação em relação ao comportamento silvicultural dos clones. The objective of the present study was to evaluate the performance of four Eucalyptus spp. hybrid clones, propagated by cutting, micropopagation, microcutting and minicutting techniques. The study evaluated height and diameter growth characteristics, as well as the aerial biomass production, in a clonal test installed in two localities in the north of Minas Gerais State. According to the results, it can be concluded that the effects of propagation techniques did not result in expressive differences in height growth and DBH, at ages 4, 8, 16 and 24 months, for the studied clones. In relation to the aerial biomass, the results did not indicate a tendency for possible effects of the propagation techniques on clone silvicultural performance.

Bone tissue has different models of vascularization, cellular distribution, mineralization and remodeling among mammals species. A variety of dietary habits associated with the mode of locomotion and habitat required from bats the establishment of different flying styles and some skeletal adaptations. This study aimed at examining the microscopic characteristics of mature bone tissue of Glossophaga soricina (Phyllostomidae, Chiroptera). Twelve animals of both genders were used, in which the right humerus were dissected, weighed, decalcified and submitted to routine histological processing. Semi-serial cuts of 5 micrometers were stained with hematoxylin and eosin (H.E.), picrosirius red and silver nitrate 50%. The histological preparations were subjected to histological and histomorphometric analysis. Lacunae density was significantly higher in humerus of females when compared to males (33.96 x 27.80, p = 0.02). Microscopic analysis indicated the presence of parallel collagen fibers distributed in the bone matrix. Lacunes presented various shapes and canaliculi are well distributed and individualized. Few Havers systems and canals were observed. The mature bone tissue of the humerus Glossophaga soricina share microscopic features with other mammals, however, differences in the structural organization are peculiar to this species.
