OBJETIVO: Avaliar experimentalmente a biocompatibilidade de cones de biovidro e biovitrocerâmico em cavidades evisceradas de coelhos. MÉTODOS: Foram utilizados 45 coelhos albinos submetidos à cirurgia de evisceração do olho direito, seguida da inclusão de cones de biovidro e dois tipos de biovitrocerâmicos (chamados de FI e FII) na cavidade escleral. Os animais foram sacrificados em três momentos (7, 90 e 180 dias). Os parâmetros avaliados foram: peso, exame clínico diário, exames bioquímicos, avaliação histológica, exame morfométrico. RESULTADOS: Os animais mantiveram-se saudáveis durante o experimento, não tendo ocorrido extrusão do implante em nenhum animal. O exame morfológico mostrou que houve a formação de pseudocápsula ao redor dos cones, com superioridade dos cones de biovidro e biovitrocerâmico FI, os quais apresentaram menor reação inflamatória e menor formação da pseudocápsula ao redor dos cones que os demais. A reação inflamatória foi mais intensa após 7 dias da colocação dos cones, diminuindo em direção aos 180 dias, sendo menos intensa nos coelhos que receberam cones de biovidro. CONCLUSÃO: Os cones de biovidro e biovitrocerâmico FI e FII podem ser úteis para a reparação da cavidade anoftálmica, com melhor resposta quando se usa cones de biovidro e de biovitrocerâmico FI.

OBJETIVOS: Este estudo visa a analisar os efeitos, a longo prazo, de cinco diferentes tratamentos sobre o controle metabólico de ratos diabéticos aloxânicos. MÉTODOS: Foram analisados 7 grupos experimentais, com 50 ratos cada um, sendo: GN o grupo controle normal; GD o grupo controle diabético, sem tratamento; GI, GA e GIA os grupos tratados, respectivamente, com insulina, acarbose e associação insulina + acarbose; GTIL o grupo tratado com transplante de ilhotas de Langerhans; e o GTPD o grupo tratado com transplante pancreatoduodenal heterotópico. Parâmetros clínicos (peso, ingestão hídrica, ingestão alimentar e diurese) e laboratoriais (glicemia, glicose urinária e insulina plasmática) foram avaliados em todos os animais, no início do experimento, e após 1, 3, 6, 9 e 12 meses de seguimento. RESULTADOS: À exceção do GN, mortalidade foi observada em todos os grupos experimentais no seguimento de 12 meses (GD= 50%; GI= 20%; GA= 26%; GIA= 18%; GTIL= 4%; GTPD= 20%). em GD, GI, GA e GIA os óbitos ocorreram por distúrbios metabólicos ou hidroeletrolíticos e/ou pneumonia, diarréia e caquexia; em GTIL e GTPD todos os óbitos ocorreram por falhas técnicas no pós-operatório até 72h. Animais dos grupos GI, GA e GIA tiveram melhora significativa (p < 0,05) de todos os parâmetros clínicos e laboratoriais observados em ratos diabéticos, sem diferença de efetividade entre os tratamentos. Porém, os resultados observados nestes grupos, biologicamente não foram comparáveis aos observados em GTIL e GTPD, onde observou-se correção completa, aos níveis normais, de todas as variáveis analisadas (p<0,01). CONCLUSÕES: Os tratamentos convencionais com insulina, acarbose e insulina + acarbose melhoraram o estado diabético grave dos ratos tratados, contudo, a eficácia dos tratamentos foi significativamente inferior à oferecida pelo GTIL e GTPD.

Obstructive Sleep Apnea Syndrome (OSAS) is characterized by snoring and / or repetitive pauses in breathing during sleep associated with hypoxemia and hypercapnia. Affects approximately 1-3% of children, especially preschoolers. There is an association of OSAS with negative impact on neurocognitive development. However, there are few studies using protocols to assess cognition and behavioral disorders in children with OSAS. The objective of this study was to analyze the major studies related to the topic within the last two decades. The main studies published between 1995 to 2011 were identified through MEDLINE and LILACS databases. We selected the most relevant for OSAS in children, neurocognitive effects and association between obstructive disorders / OSAS in the target population (children). It was concluded that the studies analyzed showed that there is strong evidence regarding the overlapping of OSAS in children with neurocognitive disorders and that treatment of OSAS has positive impact on neurocognitive development.

This article aims to discuss the role of digital technology in the process of collecting and analyzing data in qualitative research. We present two qualitative studies, with different objectives and contexts, that illustrate how data can be collected using different media and how they may shape the researcher's analysis and the results. Based on a theoretical perspective in which knowledge is seen as being produced by a collective of humans-with-media, as opposed to an individual or collective of humans, we believe that the technology used to produce knowledge and to analyze the data conditions the findings. Thus, technologies play a key role in doing research and the scientific knowledge generated from it.

There are several researches on evaluation of urban public space, but not all establish a relationship between the configuration of spaces with the thermal environment, ergonomics and environmental behavior of users. To understand this relationship, the aim of this paper is to present the model DEPAN (Design for Permanence and Attractiveness in niches open spaces of conviviality), based on graphical meshes, which were designed to evaluate the influence of design and ergonomics of open public spaces in the human thermal comfort and the ways in which users appropriate the space. Its applicability is demonstrated through a case study conducted in a park in the city of Bauru-SP. To perform this evaluation public space niches were chosen. They were formed by morphological elements and street furniture and defined by their spatial arrangements. The collected data were incorporated into a Geographic Information System (GIS), which allowed the overlay of meshes. The results indicate that the DEPAN model allows the verification of the spatial characteristics, thermal quality and ergonomic design generated by spaces, as well as the evaluation of the influence of these aspects in the way of using the spaces. The model allows the generation of a classification for every niche and set a value for the level of service offered.

The study presents the application of an ergonomic method based on graphical mesh, created to analyze the attributes of public open space and that influence on their usability. It was based on DePAN method, created to classify the service level offered by niches present in open relationship spaces. However, this method adopted Geographical Information System (GIS ) to make maps that represent the space attributes. This study proposed an adaptation of this method, which replaces GIS by AutoCAD software to generate maps . The goal is to test the feasibility and efficiency of producing maps in AutoCAD software to represent the service niches level. An relashionship area on a college campus for data collecting in graphical meshes and maps confection. By applying the graphical mesh the attributes of that space were evaluated to help promote people permanence on site. Although the process through AutoCAD seems to be harder by being mechanical it guarantees a satisfactory result for analysis, resembling images generated by GIS. Therefore, it is concluded that it’s possible to represent graphically the riches service level.

Objective: to describe technical complaints and adverse drug events reported in a sentinel hospital in São Paulo state in 2009 and 2010. Methods: This is a descriptive study. Information was obtained from the sentinel hospital Risk Management database. Results: we found 199 reports related to drugs: 70.0% were technical complaints, 21.0% ineffective therapy and 9.0% adverse reaction to medication. The pharmacological groups with highest number of reports were: drugs that act on alimentary tract and metabolism (25.1%), the nervous system (25.1%) and anti-infective drugs for systemic use (22.1%). Conclusion: technical complaints and adverse drug events were frequent, despite recognized underreporting. The characterization of these events could inform the adoption of control measures and permanent educational actions in health services in order to prevent their occurrence.

Labdane diterpenes exhibit important bioactivities such as cardiovascular effects in rats as well as effects in the treatment of autoimmune diseases and Alzheimer syndrome. Recently, the labdane diterpenes ent-13-epi-manoil oxide, ribenone and ribenol were isolated from Croton palanostigma. The computational method DFT/B3LYP/cc-pVDZ was used to optimize the structures of these diterpenes and to calculate infrared data. Chemical shifts (δH and δC) of the minimum energy structures (local minimum) were calculated and compared with the experimental data. Comparison of the NMR data by simple linear regression (SLR) showed satisfactory statistical results with a correlation coefficient (R2) and predictive ability (Q2) of over 98%. The predicted NMR data were used to confirm the δH values that have not been published.

Laurencia dendroidea shows high inter- and intrapopulation variability in the amount of the sesquiterpene elatol, caused by genetic variation as well as environmental factors. To test the independent effect of physical and nutritional conditions, the growth and the levels of elatol in L. dendroidea clones were evaluated under different conditions of temperature, salinity, irradiance, and culture medium in the laboratory. Growth of L. dendroidea was clearly affected by all these factors, but elatol levels were influenced only by temperature and salinity. Better conditions for growth did not produce a similar effect on elatol production in L. dendroidea, contradicting the carbon/nutrient balance and growth/differentiation balance models. On the contrary, severe conditions of temperature and salinity promoted a decrease in elatol levels, as predicted by the environmental stress model. Our results using clones indicated that abiotic factors clearly take part in fostering chemical variations observed in natural populations, in addition to genetic factors, and can promote differential susceptibility of plant specimens to natural enemies.

The broad goals of verifiable visualization rely on correct algorithmic implementations. We extend a framework for verification of isosurfacing implementations to check topological properties. Specifically, we use stratified Morse theory and digital topology to design algorithms which verify topological invariants. Our extended framework reveals unexpected behavior and coding mistakes in popular publicly available isosurface codes.
