Este trabalho faz uma análise de convergência espacial para o processo de desmatamento em 139 municípios do estado de Mato Grosso durante o período de 2000 a 2008. Primeiramente, realiza-se uma análise exploratória de dados espaciais (Aede), que detecta a presença de autocorrelação espacial entre as taxas de desmatamento dos municípios da referida região. Dessa forma, pode-se considerar que o desmatamento não segue um processo aleatório no estado de Mato Grosso. Após isso, são estimados alguns modelos de β convergência, indicando que o modelo de erro espacial é o que fornece melhores resultados. Contudo, mesmo o coeficiente β sendo estatisticamente significativo para todos os períodos, apresenta sinal positivo, sugerindo que não ocorre convergência, mas sim incremento das disparidades regionais no processo de desmatamento.

Current dental treatments search for alternatives to achieve restablishment of esthetics and function. The increased demand for high esthetic patterns stimulates an interaction between the dental specialties towards a comprehensive treatment in order to solve slinical cases effectively. Knowing the components involved in the dental smile harmony is essential for treatment planning and implementation. It is also important to be aware of the changes that may impair suck harmony and become a patient's complaint. This article addresses a multidisciplinary treatment that involved the integration between Periodontics and Restorative Dentistry. After the surgical-restorative planning, periodontal procedures were performed to obtain an adequate balance between the teeth and soft tiessues.

The development of new dental materials has expanded dental therapeutic modalities ensuring excellence in aesthetic restorative treatments. Thus, the direct restorative procedures have been used in cases of dental reconstruction allowing an effective treatment with a low cost, while preserving healthy tooth structure. However, the clinician must be used to the techniques and the material in order to ensure longevity and success in the direct restorative procedure. The aim of this paper is to descrive, after completion of periodontal surgical procedures, the direct restorative step performed for dental reconstruction and diastema closure. The integration between Restorative Dentistry and periodontics enableb the restoration of a harmonious smile in a conservative manner, ensuring aesthetics and patient stisfaction.

Two experiments were carried out to evaluate the effect of adding glutamine, fish oil or yeast cellular wall to the diet of weaned piglets on the expression of the enzyme ornithine decarboxylase (ODC), the protein content and DNA in small intestine samples and on performance. In the first experiment, 24 weaned piglets were used to measure the performance at the phases prestarter, starter 1 and starter 2. Four diets were tested (T1 -basal diet (BD); T2 -BD + 1% of glutamine; T3 -BD + 0,2% of yeast cellular wall; T4 -BD + 5% of fish oil). At the second experiment 45 weaned piglets were used and distributed in a randomized block design, in factorial outline with four diets and three slaughter ages (on the day of weaning, on the seventh and fourteenth days postweaning). The tested diets did not alter the piglets' performance in none of the phases. There was reduction of the expression of the ODC enzyme, of the protein concentration and of the relationship protein/DNA to the seven days postweaning, with increase of the values on the 14th day, evidencing a state of hypotrophy of the mucous membrane, suggesting that the process of protein synthesis in the small intestine was diminished in the first week after weaning, but it presented recovery signs in the second week.

The aim of this study was to evaluate maternal stress and anxiety and the quality of interaction of 10 mothers and their 0-3-month-old babies with Pierre Robin Sequence hospitalized in a university hospital. We used the Inventory of Stress Symptoms for Adults to evaluate stress and the State-Trait Anxiety Inventory to assess anxiety of the mothers, and a protocol to assess the recording of the mother-infant interaction. The results showed high levels of maternal stress and anxiety. A statistically significant inverse relationship was found: the higher the maternal anxiety and stress, the lower was the mother-infant interaction. The results indicate that work needs to be done to minimize the anxiety and stress of mothers with inpatient babies in order to encourage interaction.
