    Get PDF
    A cidade de Montes Claros situa-se estrategicamente no Norte de Minas Gerais, apresentando boas alternativas e possibilidades de investimento; sendo considerada elo de ligação entre as regiões urbanas do país, por isso chamada “Centro Polarizador” no norte-mineiro. Sua posição geográfica, proporciona a ela ser pólo de atração para vários serviços lucrativos, o que tem levado ao aumento das imigrações por parte da população circunvizinha, gerando o êxodorural. Este, pode ser comprovado pelo Bairro Cidade Industrial, que surgiu em 1993 na periferia da cidade. Essa ocupação desmedida acabou por afetar o planejamento urbano daquela região, provocando alterações no espaço geográfico. Neste contexto, têm-se como objetivo o estudo das manifestações e avanços urbano-industriais da cidade de Montes Claros a partir de 1970, enfatizando a origem do Bairro e suas transformações espaciais e sócio-ambientais. Buscou-se embasamento teórico para realização do estudo e, através de elaboração de questionário, realizou-se a parte prática da pesquisa, com posterior tabulação dos dados. Pode-se perceber as transformações urbano-espaciais que marcaram a região, tornando visível a necessidade de se transformar a história daquele lugar com investimentos sócio-econômicos/educacionais que proporcionarão a mudança da qualidade de vida

    Effect of epithelial debridement on human cornea proteoglycans

    Corneal transparency is attributed to the regular spacing and diameter of collagen fibrils, and proteoglycans may play a role in fibrillogenesis and matrix assembly. Corneal scar tissue is opaque and this opacity is explained by decreased ultrastructural order that may be related to proteoglycan composition. Thus, the objectives of the present study were to characterize the proteoglycans synthesized by human corneal explants and to investigate the effect of mechanical epithelial debridement. Human corneas unsuitable for transplants were immersed in F-12 culture medium and maintained under tissue culture conditions. The proteoglycans synthesized in 24 h were labeled metabolically by the addition of 35S-sulfate to the medium. These compounds were extracted by 4 M GuHCl and identified by a combination of agarose gel electrophoresis, enzymatic degradation with protease and mucopolysaccharidases, and immunoblotting. Decorin was identified as the main dermatan sulfate proteoglycan and keratan sulfate proteoglycans were also prominent components. When the glycosaminoglycan side chains were analyzed, only keratan sulfate and dermatan sulfate were detected (~50% each). Nevertheless, when these compounds were 35S-labeled metabolically, the label in dermatan sulfate was greater than in keratan sulfate, suggesting a lower synthesis rate for keratan sulfate. 35S-Heparan sulfate also appeared. The removal of the epithelial layer caused a decrease in heparan sulfate labeling and induced the synthesis of dermatan sulfate by the stroma. The increased deposit of dermatan sulfate proteoglycans in the stroma suggests a functional relationship between epithelium and stroma that could be related to the corneal opacity that may appear after epithelial cell debridement.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de BioquímicaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de OftalmologiaUNIFESP, EPM, Depto. de BioquímicaUNIFESP, EPM, Depto. de OftalmologiaSciEL

    Get PDF
    A Educação Ambiental (EA) tem autonomia suficiente, pelos seus pressupostos, de redefinir o tipo de cidadão que se queira formar e os novos espaços territoriais a serem construídos para a humanidade. Nota-se a necessidade de articular as propostas e os objetivos da EA, no que tange as práticas de ensino aprendizagem em seus diversos níveis e modalidades, formais e informais. É importante também conhecer as particularidades de cada espaço, respeitando sua identidade cultural, ética, socioeconômica de sua população. Diante desse exposto, o objetivo deste trabalho é conhecer as políticas de integração que são desenvolvidas dentro do Presídio Regional de Montes Claros - PRMC4***, tomando como principal vertente a EA e compreender, como esses processos se articulam na humanização e promoção à saúde dos presos. A metodologia empregada foi pautada em uma discussão ampla em diversas referências teóricas de autores e pesquisadores imbuídos na Educação Ambiental, Território, Espaço Geográfico, na Promoção da Saúde e nos Sistemas Prisionais. Em seguida, foi elaborado um estudo de caso no PRMC, com visitas, onde os objetivos foram diagnosticados com maior afinco. A contribuição deste trabalho consiste em fortalecer as práticas da EA - ferramenta fundamental na elaboração de novos paradigmas entre sociedade e ambiente

    Educação ambiental e Geografia: uma contribuição à sociedade em via de possíveis mudanças

    Get PDF
    A sociedade moderna é consumista, mas não alheia às transformações oriundas da globalização e trouxe impactos principalmente ao meio ambiente. Fato este que despertou a sociedade para um possível processo de transição, tornando-a mais consciente de seu papel na coletividade. Isso implica mudança de atitude e de comportamento que podem ser adquiridas com a inserção da Educação Ambiental nas escolas e no cotidiano da população. O que despertou o interesse por este trabalho que tem como objetivo analisar a importância e contribuição da Educação na compreensão da dinâmica sociedade e natureza e sua responsabilidade diante dos atuais problemas ambientais. O procedimento metodológico se deu por pesquisa bibliográfi ca. Neste sentido a Educação Ambiental deve ser implantada como processo educativo e integrada a disciplina de Geografi a que seria um instrumento fundamental para orientar as ações futuras a respeito do Meio Ambiente e sua manutenção. Este deverá ser planejado de forma operacional, almejando novas oportunidades de desenvolvimento sustentável. A partir do estudo realizado é possível inferir que a Geografi a e a Educação Ambiental são apenas possibilidades de acertos e erros, mas, sempre deixando sua contribuição para a construção de conhecimentos e posteriores planejamentos, com vistas a uma nova ética sócio-ambiental

    The objective of this study was to evaluate the performance characteristics of the morphometric sheep of the Santa Inês breed, recently-Paris, with their respective Lamb Texel x Santa Inês, a paste, in creep feeding system. For this purpose, 30 Sheeps and theirs and the respective lamb were used for natural breastfeeding for 60 days until weaning. The randomized blocks used, with two Treatments (absence of the presence of the private feeder), with 10 repetitions, being shadow sheep by repetition municipality or relative lamb. In Studies on the termination of two Cordeiro, the bone of heavy animals was measured at the beginning and at the end of the experiments (25 days), using the 30-Cordeiro weaned. The randomized blocks, used with three Treatments (0.400 of 800 g of concentrate / lamb / DIA). There was no difference in weight between the sheep outside of Cordeiro (supplemented or not). There were no two treatments effect on the morphometric characteristics among the sheep outside between the Lamb bone. The use of creep feeding did not provide greater weight gain in recovery to give weight to give infant sheep, nor did it provide greater weight gain, we Lamb supplemented in relation to this not supplemented during breastfeeding, but the supplementary feed 400g / animal / day in the finishing phase it shows better results for I gained two lambs of weight.Brazilian sheep farming has been gaining prominence with the increase in meat production, seeking more efficiency and profitability. Thus, the creation of the Santa Inês breed has stood out, as it is highly adaptable to different types of environments and has potential for meat production. The objective of this study was to evaluate the performance characteristics of the morphometric sheep of the Santa Inês breed, recently-Paris, with their respective lamb Texel x Santa Inês, a paste, in creep feeding system. For this purpose, 30 Sheeps and theirs and the respective lamb were used for natural breastfeeding for 60 days until weaning. The randomized blocks used, with two treatments (absence of the presence of the private feeder), with 10 repetitions, being shadow sheep by repetition municipality or relative lamb. In studies on the termination of two lambs, the bone of heavy animals was measured at the beginning and at the end of the experiments (25 days), using the 30-lambs weaned. The randomized blocks, used with three treatments (0, 400 and 800 g of concentrate/lamb/day). There was no difference in weight between the sheep outside of lamb (supplemented or not). There were no two treatments effect on the morphometric characteristics among the sheep outside between the lamb bone. The use of creep feeding to supplement lambs kept on natural lactation does not provide weight gain in sheep, nor does it provide weight gain in supplemented lambs. Lamb supplementation does not influence the morphometric characteristics of ewes and lambs during lactation. Private supplementation during breastfeeding does not increase lambs’ weight gain until weaning, but food supplementation, via creep feeding with 400 g/animal/day, in the finishing phase presents the best results for weight gain

    The use of an adequate method for evaluation of the adhesion of root canal filling materials provides more reliable results to allow comparison of the materials and substantiate their clinical choice. The aims of this study were to compare the shear bond strength (SBS) test and push-out test for evaluation of the adhesion of an epoxy-based endodontic sealer (AH Plus) to dentin and gutta-percha, and to assess the failure modes on the debonded surfaces by means of scanning electron microscopy (SEM). Three groups were established (n=7): in group 1, root cylinders obtained from human canines were embedded in acrylic resin and had their canals prepared and filled with sealer; in group 2, longitudinal sections of dentin cylinders were embedded in resin with the canal surface smoothed and turned upwards; in group 3, gutta-percha cylinders were embedded in resin. Polyethylene tubes filled with sealer were positioned on the polished surface of the specimens (groups 2 and 3). The push-out test (group 1) and the SBS test (groups 2 and 3) were performed in an Instron universal testing machine running at crosshead speed of 1 mm/min. Means (±SD) in MPa were: G1 (8.8±1.13), G2 (5.9±1.05) and G3 (3.8±0.55). Statistical analysis by ANOVA and Student's t-test (a=0.05) revealed statistically significant differences (p<0.01) among the groups. SEM analysis showed a predominance of adhesive and mixed failures of AH Plus sealer. The tested surface affected significantly the results with the sealer reaching higher bond strength to dentin than to gutta-percha with the SBS test. The comparison of the employed methodologies showed that the SBS test produced significantly lower bond strength values than the push-out test, was skilful in determining the adhesion of AH Plus sealer to dentin and gutta-percha, and required specimens that could be easily prepared for SEM, presenting as a viable alternative for further experiments

    Get PDF
    Objectives: This series of 12 cases intends to raise awareness to Lichen Sclerosus, by illustrating its main clinical characteristics and complications, and by highlighting the importance of its early diagnosis.&nbsp;Methods: All of the patients discussed were attended at the Institute of Gynecology of the Federal University of Rio de Janeiro (UFRJ, Rio de Janeiro, Brazil), after being referred from primary care family medicine facilities. Results:&nbsp;We present 12 cases. The mean ages at the beginning of symptoms and clinical diagnosis were 6 and 9.25 years, respectively. The mean delay for diagnosis was 3.2 years. Vulvar pruritus and hypochromic macules were the most common initial symptoms. Complications included the fusion of&nbsp;the labia minora&nbsp;and&nbsp;clitoris entrapment. Cases with an earlier diagnosis had better responses to treatment with ultra-potent corticosteroids such as Clobetasol propionate ointment 0.05%.&nbsp;Conclusion: Diagnostic delay of LS leads to its progression and long-term physical-psychological consequences. It must be remembered as a differential diagnosis of vulvar pruritus in childhood
