    This study aimed to analyze the evolution and participation of forestry products in the Gross Domestic Product (GDP) of the Brazilian forest-based sector, from 2000 to 2019. To do so, secondary data collected from Instituto Brazilian Geography and Statistics, considering historical series referring to the produced/commercialized quantity in silviculture (m³) and production value in silviculture (Thousand dollars). To obtain the price evolution (P) of each product, the equation was applied, using the quotient between the value of the production and its respective produced quantities. The analysis of the evolution of the GDP, on the other hand, was conducted by calculating the geometric growth rate (GGR). In relation to the real GDP, the decline started in 2011, however in a more moderate way. The real Brazilian GDP presented a positive rate of 3.51%, different from the silviculture rate that was negative for all products, triggering a decline in the forestry sector rate

    INTRODUCTION: Recently a number of studies have been published on quantitative measures mainly for the prominence of digital imaging processing, which is a non-invasive and precisely procedure. This study assessed measures in anterior view before and after surgery of patients who underwent otoplasty using computer analysis of digital images. METHODS: A retrospective study was performed on a consecutive series from February 2014 to April 2015. Measures were done in the upper third, middle and bottom of the ears. RESULTS: Of 103 patients, 47 were men and 56 women. We used the technique of weakening the cartilage by making multiple posterior islands associated with non-absorbable suture in 56 patients, an isolated conchal cartilage resection in 1 patient and combination of all techniques in 47 patients. The result of auricle measure in frontal viewing at previous measured points performed using computer analysis showed a significant mean reduction in the third month after surgery. CONCLUSION: Digital image assessment can estimate auricle measure with high repeatability, corroborating with the use of digital images in noninvasive procedures as less expensive and highly available option in clinical practice. The computed anthropometric analysis of digital images in direct frontal view using images taken before and after surgery is an alternative method for traditional measurements to evaluate results in otoplasties

    Pigeon pea (Cajanus cajan) is a shrub legume with multiple uses. The species has a very well-organized and deep root system, which allows it to resist drought. In addition, pigeon pea can associate with nitrogen-fixing bacteria. These characteristics make pigeon pea a viable alternative in the recovery of degraded soils. As green manure, it guarantees more nutrients for the main crop, thanks to its ability to supply nitrogen to the system. It is a source of food for humans and animals and still adapts well in semi-arid regions. Pigeon pea has shown good results under Cerrado conditions, being an option for diversifying agricultural systems in the region. For the incorporation of this species in agricultural systems, information is needed on the adaptation of the genotypes to the region of cultivation and the destination of the plantation, given the genetic variability and the multiple uses that the species has. However, this information is still scarce and even the existing information needs to reach more farmers and the population in general. In this sense, this review aims to address the main potential use of pigeon pea in the Brazilian cerrado region.O feijão guandu (Cajanus cajan) é uma leguminosa arbustiva que apresenta múltiplos usos. A espécie possui um sistema radicular muito bem organizado e profundo, o que lhe permite resistir a seca. Além disso, o feijão guandu apresenta a capacidade de se associar a bactérias fixadoras de nitrogênio. Essas características fazem com que o guandu seja uma alternativa viável na recuperação de solos degradados. Como adubo verde garante mais nutrientes para a cultura principal, graças a sua capacidade de aportar nitrogênio ao sistema. É fonte de alimento para humanos e animais, e ainda se adapta bem nas regiões semiáridas. O guandu tem apresentado bons resultados nas condições do Cerrado, sendo uma opção para a diversificação dos sistemas agropecuários na região. Para a incorporação dessa espécie em sistemas agropecuários são necessárias informações sobre a adaptação dos genótipos à região de cultivo e sobre a destinação do plantio, visto a variabilidade genética e os múltiplos usos que a espécie possui. Entretanto, essas informações ainda são escassas e mesmo as existentes precisam alcançar mais os agricultores e a população em geral. Neste sentido, essa revisão tem como objetivo abordar as principais potencialidades de uso do feijão guandu na região do cerrado brasileiro

    Okra is a vegetable of high nutritional value, but highly perishable when stored in natura. Cookies are products of great popular acceptance and allow the use of alternative flours. The objective was to evaluate cookies made with partial substitution of wheat flour for okra. Okra fruits were dried to obtain the flour. This was applied in biscuit formulations at concentrations of 0 (A), 5 (B), 10 (C) and 15% (D). The cookies were evaluated for the difference in mass, thermal factor, yield, humidity, ash, fibers, proteins, lipids, carbohydrates, caloric value, presence of Coliforms at 45 ° C, positive coagulase Staphylococcus and Samonella sp., In addition to the sensory evaluation acceptance and purchase intention. The dough, ash content, fiber and protein of the cookies enriched with okra flour were higher. The carbohydrate content and caloric value was higher in formulation A. All cookies are within the microbiological standards required by law. Sensory acceptance and purchase intention were superior in formulations A and B. The differences between the cookies are due to the different composition of the okra and vary according to the concentration in which it is added. Formulation B obtained better nutritional quality without interfering with its good sensory acceptance.Okra is a vegetable of high nutritional value, but highly perishable when stored in natura.

    Fish protein hydrolysates (FPH) obtained from industrial processing residues are sources of bioactive peptides. The enzymatic hydrolysis process is essential in obtaining specific bioactivities such as inhibition of the enzyme acetylcholinesterase (AChE). In this study the effect of different hydrolysis conditions on the properties of FPH to inhibit the enzyme acetylcholinesterase. A chemometric evaluation, based on a central composite rotatable design and principal component analysis, was applied to select hydrolysis conditions with best yield, degree of hydrolysis and acetylcholinesterase inhibition. Experimental design results for AChE inhibition were between 10.51 and 40.45% (20, 30 and 50 mg.mL-1 of FPH), and three hydrolysis conditions were selected based on PCA evaluation. The amino acids profile, FTIR and AChE inhibition kinetics were evaluated. Results showed a mixed type of inhibition behavior and, the docking molecular analyzes suggest that the inhibition AChE occurred due to the basic amino acids, mainly by arginine.Authors thank to CNPq (Chamada Universal– MCTI/CNPq N◦ 28/2018, Process 421541/2018-0) and Fundação Araucária (convênios 40/2016, 53/2019 and 039/2019) for the financial support.

    OBJECTIVE: Low birth weight children are unusual among well-off families. However, in Brazil, low birth weight rate was higher in a more developed city than in a less developed one. The study objective was to find out the reasons to explain this paradox. METHODS: A study was carried out in two municipalities, Ribeirão Preto (Southeastern Brazil) and São Luís (Northeastern Brazil), which low birth weight rates were 10.7% and 7.6% respectively. Data from two birth cohorts were analyzed: 2,839 newborns in Ribeirão Preto in 1994 and 2,439 births in São Luís in 1997-1998. Multiple logistic regression analysis was performed, adjusted for confounders. RESULTS: Low birth weight risk factors in São Luís were primiparity, maternal smoking and maternal age less than 18 years. In Ribeirão Preto, the associated variables were family income between one and three minimum wages, maternal age less than 18 and equal to or more than 35 years, maternal smoking and cesarean section. In a combined model including both cohorts, Ribeirão Preto presented a 45% higher risk of low birth weight than São Luís. When adjusted for maternal smoking habit, the excess risk for low birth weight in Ribeirão Preto compared to São Luís was reduced by 49%, but the confidence interval was marginally significant. Differences in cesarean section rates between both cities contributed to partially explain the paradox. CONCLUSIONS: Maternal smoking was the most important risk factor for explaining the difference in low birth weight between both cities. The other factors contributed little to explain the difference in low birth weight rates.OBJETIVO: O baixo peso ao nascer é incomum em recém-nascidos de maior nível socioeconômico. Contudo, no Brasil, a taxa de baixo peso ao nascer foi maior em cidade mais desenvolvida do que em município menos desenvolvido. O objetivo do estudo foi buscar razões para explicar este paradoxo. MÉTODOS: O estudo foi realizado em Ribeirão Preto (SP) e em São Luís (MA), cujas taxas de baixo peso ao nascer eram 10,7% e 7,6%, respectivamente. Foram analisados dados de duas coortes de nascimentos: 2.839 recém-nascidos em Ribeirão Preto em 1994 e 2.439 em São Luís em 1997/98. Foi realizada análise de regressão logística múltipla, ajustada para efeito de confusão. RESULTADOS: Os fatores de risco associados em São Luís foram primiparidade, idade materna menor que 18 anos e tabagismo materno. Em Ribeirão Preto, os fatores de risco foram: renda familiar entre um e três salários-mínimos, idade materna menor que 18 e igual ou maior que 35 anos, tabagismo materno e parto cesáreo. Em modelo conjunto incluindo ambas as coortes, Ribeirão Preto apresentou risco 45% maior para em relação a São Luís. Quando ajustado para tabagismo materno, o excesso de risco em Ribeirão Preto, reduziu-se em 49%, mas o intervalo de confiança esteve marginalmente significante. Diferenças nas taxas de cesárea entre as duas cidades contribuíram para explicar uma porção adicional desse paradoxo. CONCLUSÕES: O tabagismo materno foi o fator de risco mais importante capaz de explicar a diferença no baixo peso ao nascer entre as duas cidades. Os outros fatores pouco contribuíram para explicar a diferença nas taxas de baixo peso ao nascer
