The present study evaluates the performance of three numerical weather forecasting models: Global Forecast System (GFS), Brazilian Regional Atmospheric Modelling System (BRAMS) and ETA Regional Model (ETA), by means of the Mean Error (ME) and the Root Mean Square Error (RMSE), during the most rainy four months period (January to April 2012) on Eastern Amazonia. The models displayed errors of superestimation and underestimation with respect to the observed precipitation, mainly over center-north of Pará and all of Amapá, where the precipitation is higher. Among the analyzed models, GFS shows the best performance, except during January and March, when the model to underestimated precipitation, possibly due to the anomalously high values recorded.

We review the recent progress that have led to the development of porous materials based on cellulose nanostructures found in plants and other resources. In light of the properties that emerge from the chemistry, shape and structural control, we discuss some of the most promising uses of a plant-based material, nanocellulose, in regenerative medicine. Following a brief discussion about the fundamental aspects of self-assembly of nanocellulose precursors, we review the key strategies needed for material synthesis and to adjust the architecture of the materials (using three-dimensional printing, freeze-casted porous materials, and electrospinning) according to their uses in tissue engineering, artificial organs, controlled drug delivery and wound healing systems, among others. For this purpose, we map the structure-property-function relationships of nanocellulose-based porous materials and examine the course of actions that are required to translate innovation from the laboratory to industry. Such efforts require attention to regulatory aspects and market pull. Finally, the key challenges and opportunities in this nascent field are critically reviewed.

AIM： To evaluate the prevalence and clinical characteristics of Nonalcoholic fatty liver disease （NAFLD） among asymptomatic Brazilian adolescents. METHoDS： Transversal observational study included asymptomatic adolescents with central obesity from private and public schools in Salvador-Bahia, northeastern Brazil. The children answered a questionnaire that in- cluded age, gender, race, and medical history, and were submitted to a complete physical exam and abdominal ultrasound. Biochemical exams included： ALT, AST, GGT, C reactive protein （CRP）, fasting glucose, insulin, cholesterol and triglycerides. Criteria for NAFLD included： the presence of steatosis in ultrasound and/or high level of ALT, negative or occasional historic of intake of alcohol （4 140 g/wk）, negative investigation for hepatitis A, B, C, auto-immune hepatitis, Wilson disease and ***： From october, 2005 to october, 2006, the study included 1801 subjects between 11 and 18 years of age and a mean age of 13.7± 2.0 years. one hun- dred ninety-nine had central obesity. The prevalence of NAFLD was 2.3%, most of whom were male and white. Insulin resistance （IR） was observed in 22.9% of them and had positive correlations with ALT and GGT （P 〈 0.05）. Elevated CRP was observed in 6.9% of the cases; however, it was not associated with WC, IR or liver enzymes. CoNCLUSIoN： The prevalence of NAFLD in Brazilian adolescents was low. The ethnicity may have influence this frequency in the population studied, which had a large proportion of African descendents.
