OBJETIVO: Avaliar a contribuição do hiperandrogenismo para o desenvolvimento da síndrome metabólica (SM) em mulheres obesas com ou sem Síndrome dos Ovários Policísticos (SOP). MÉTODOS: Estudo transversal retrospectivo no qual foram incluídas 60 mulheres obesas com fenótipo clássico da SOP - Consenso de Rotterdam - e 70 obesas sem SOP. A SM foi diagnosticada pelos critérios do NCEP-ATP III. A obesidade foi definida pelo índice de massa corpórea e o hirsutismo, pelo Índice de Ferriman-Gallwey (IFG). As dosagens realizadas foram: testosterona total, sulfato de dehidroepiandrosterona (SDHEA), insulina e glicose, colesterol total, HDL e triglicerídios. A resistência insulínica (RI) foi avaliada pelo HOMA-IR e pelo índice de sensibilidade à insulina de Matsuda e De Fronzo. A analise estatística foi realizada com o teste t de Student, teste do χ² e análise de regressão logística multivariada (p<0,05). RESULTADOS: As obesas com SOP apresentaram significativamente maiores valores de IFG (15,4±6,1), circunferência da cintura (105,6±11,4 cm), testosterona (135,8±71,4 ng/dL), SDHEA (200,8±109,2 µg/dL), HOMA-IR (8,4±8,5) e menores valores de ISI (2,0±1,8) quando comparadas às obesas não SOP (3,2±2,1; 101,4±9,2 cm; 50,0±18,2 ng/dL; 155,0±92,7 µg/dL; 5,1±4,7; 3,3±2,7, respectivamente) (p<0,05). A frequência de SM foi significativamente maior nas obesas com SOP (75%) do que nas obesas não SOP (52,8%) (p=0,01). A análise multivariada não demonstrou contribuição das variávies IFG, testoterona total e SDHEA para o desenvolvimento da SM (p>0,05). CONCLUSÃO: Mulheres obesas com SOP apresentam maior frequência de SM quando comparadas às obesas não SOP. O hiperandrogenismo não mostrou influência nesse grupo de mulheres estudadas.

There are strong uncertainties regarding LAI dynamics in forest ecosystems in response to climate change. While empirical growth & yield models (G&YMs) provide good estimations of tree growth at the stand level on a yearly to decennial scale, process-based models (PBMs) use LAI dynamics as a key variable for enabling the accurate prediction of tree growth over short time scales. Bridging the gap between PBMs and G&YMs could improve the prediction of forest growth and, therefore, carbon, water and nutrient fluxes by combining modeling approaches at the stand level.Our study aimed to estimate monthly changes of leaf area in response to climate variations from sparse measurements of foliage area and biomass. A leaf population probabilistic model (SLCD) was designed to simulate foliage renewal. The leaf population was distributed in monthly cohorts, and the total population size was limited depending on forest age and productivity. Foliage dynamics were driven by a foliation function and the probabilities ruling leaf aging or fall. Their formulation depends on the forest environment.The model was applied to three tree species growing under contrasting climates and soil types. In tropical Brazilian evergreen broadleaf eucalypt plantations, the phenology was described using 8 parameters. A multi-objective evolutionary algorithm method (MOEA) was used to fit the model parameters on litterfall and LAI data over an entire stand rotation. Field measurements from a second eucalypt stand were used to validate the model. Seasonal LAI changes were accurately rendered for both sites (R-2 = 0.898 adjustment, R-2 = 0.698 validation). Litterfall production was correctly simulated (R-2 = 0.562, R-2 = 0.4018 validation) and may be improved by using additional validation data in future work. In two French temperate deciduous forests (beech and oak), we adapted phenological sub-modules of the CASTANEA model to simulate canopy dynamics, and SLCD was validated using LAI measurements. The phenological patterns were simulated with good accuracy in the two cases studied. However, IA/max was not accurately simulated in the beech forest, and further improvement is required.Our probabilistic approach is expected to contribute to improving predictions of LAI dynamics. The model formalism is general and suitable to broadleaf forests for a large range of ecological conditions. (C) 2014 Elsevier B.V. All rights reserved.

Dans ce texte, nous avons abordé l'enseignement des langues selon une approche constructiviste, où le sujet qui apprend et l'objet de connaissance ne se polarisent pas, mais s'articulent. Ceci signifie que personne ni rien ne sort indemne d'un processus de formation : il y a des transformations chez le sujet (apprenant) et l'objet (langues). Nous critiquons par conséquent la conception du langage et donc de la langue en tant qu'instrument de communication.

Jules Laforgue is a French Symbolist poet, he wrote poetry works such as Les complaintes, L’imitation de Notre-Dame, la lune, Le sanglot de la terre. In spite of mostly of symbolist poets write only poetry, he also dedicated himself to prose works such as Moralités Légendaires, a particular work in prose and extreme today as in the nineteenth century, he devoted himself to parody and irony. The novels that make up this book are the work of writing and tone of nuance. They refer to literary genres, without, however, respect their definitions. There are demarcation of famous texts, but that refer more to modes, themes, and aesthetic conventions. Here, the poet makes variations on familiar themes, and explore his Moralités arguments that belong to a cultural background: the myth of Hamlet, approached the novel here mentioned belong to a cultural heritage that an author set for posterity. In other novels, the author makes use of myths Greco-Latin and Judeo-Christian myths rewriting so parodic, ironic, looking for originality, doing the work of Symbolist and modern poet.

The present study aimed to analyze the effects of tooth bleaching with 10% carbamide peroxide (CP) gel on the bond strength of resin composite restorations to dentin. Material and Methods: Twenty cavities were prepared on the buccal surface of bovine teeth. After acid etching and application of bonding agent on dentin and enamel, the cavities were restored with composite resin. The specimens were divided into groups according to treatment on the surface of enamel / restoration: G1 - control (no treatment) and G2 (10% PC gel application for 8h/day during 14 days). After this period, the teeth were cut to produce beams with 0.81 mm2 cross-sectional area, which were subjected to microtensile test. The fractures were examined with a stereomicroscope and classified as cohesive in resin or dentin, adhesive, or mixed. Results: The statistical analysis (ANOVA / χ2) revealed that the factor treatment interfered with the bond strength, which was significantly higher for specimens of G2 (p <0.05). Adhesive fractures occurred in most of specimens of both groups with values ranging from 48.3% to 75%. Mixed fractures were the second more frequent in G1 and cohesive resin failure in G2. Conclusion: It was concluded that tooth bleaching with 10% of PC increased the bond strength of adhesive restorations to dentin.

The purpose of this paper was to evaluate the agreement among different methods used to estimate angular deviation of the body to determine the risk for development of upper limb musculoskeletal disorders in dentistry undergraduates. Materials and Methods: Students (n = 79) enrolled in the final year undergraduate course of the Araraquara School of Dentistry-Sγo Paulo State University-UNESP were evaluated. Photographs were taken of students performing clinical procedures. The work postures adopted by each student were evaluated by means of rapid upper limb assessment (RULA). The basis used to obtain the individual's final risk score is the measurement of the angular deviations in the neutral positions of the regions evaluated. Two methods were used to estimate the angular deviation of the body: Visual exam and Image Tool software. A RULA final risk score was attributed to each procedure the student performed (n = 333). Study of the agreement between the methods about risk of musculoskeletal disorders was conducted by means of Kappa (κ) statistics. The level of significance adopted was 5%. Results: Fair agreement (κ = 0.32) between the evaluated methods was verified. Conclusion: The risk for development of upper limb musculoskeletal disorders by dentistry undergraduates evaluated by using RULA was not in agreement with the results obtained by use of visual exam and Image Tool.
