ABSTRACT Medium-density particleboards represent an alternative for the use of lignocellulosic by-products, found in abundance and which causes environmental impacts when improperly disposed of. In this scope, the objective of this research was to evaluate the potential of multilayer particle boards, produced with sugarcane bagasse and polyurethane resin based on castor oil (PU-castor) and compare the results with the requirements established by the Brazilian standard for wood particle board (NBR 14810-2:2018). For that, the physical and mechanical properties and the resistance to humidity of multilayer particle boards with a thickness of 15 mm and medium density (600 and 750 kg.m-3) of agglomerated sugarcane bagasse particles were analyzed. with castor oil PU resin (12% for the inner layer and 15% for the outer layer). The results obtained indicated that the panels with 750 kg.m-3 presented better performance, reaching all the requirements required to classify them, according to the recommendations of the Brazilian standard for wood panels, such as P2 type panels, non-structural use in dry conditions.

RESUMO Os painéis de partículas de média densidade representam uma alternativa para uso dos subprodutos lignocelulósicos, encontrados de forma abundante e que ocasionam impactos ambientais quando descartados de forma inadequada. Nesse escopo, o objetivo desta pesquisa consistiu em avaliar o potencial de painéis de partículas multicamadas, produzidos com bagaço de cana-de-açúcar e resina poliuretana à base de óleo de mamona (PU-mamona) e confrontar os resultados com os requisitos estabelecidos pela norma brasileira de painéis de partículas de madeira (NBR 14810-2:2018). Para tanto, foram analisadas as propriedades físicas e mecânicas e a resistência à umidade, de painéis de partículas multicamadas com espessura de 15 mm e média densidade (600 e 750 kg.m-3) de partículas de bagaço de cana-de-açúcar aglomeradas com resina PU mamona (12% para camada interna e 15% para camada externa). Os resultados obtidos indicaram que os painéis com 750 kg.m-3 apresentaram melhor desempenho, atingindo todos os requisitos exigidos para classificá-los, de acordo com as recomendações da norma brasileira para painéis de madeira, como painéis do tipo P2, uso não estrutural em condições secas.

The mangosteen (Garcinia mangostana, Linn.) is a tropical fruit cultivated in the tropical forests of Southeast Asian countries. It is recognized as the queen of fruits due to its unique color, aroma, and flavor. It has been used for centuries in Southeastern Asian traditional medicine for the treatment of various diseases. Many functional molecules with high medicinal value are obtained from the pericarp of mangosteen fruit, whose major constituent is xanthone α-mangostin. Several studies have been carried out over the last decades to further investigate and understand the pharmacological properties associated with the plant and its main chemical constituents, belonging to the class of xanthones. In addition, numerous in vitro and in vivo studies related to mangosteen have been published, indicating its importance and its potential application in medicinal chemistry. Prenylated xanthones, which include α-mangostin, are secondary metabolites particularly common in plants belonging to the Clusiaceae family. These substances have been intensively investigated for their potential as biologically active agents. This article describes a critical analysis of published data related to the properties of α-mangostin, aiming to provide a more detailed view of its potential as a chemotherapeutic agent for the prevention and treatment of infectious diseases.

Abstract: En | Text: En | PDF: En

Circular chemistry (CC) is an approach for establishing chemical processes to become truly circular and sustainable. It adopts the principles of circular economy (CE), employing life cycle approaches and systems thinking, which help to understand and address the sustainability issues of chemical processes and products. Within this whole context, it is possible to identify some problems of the current lifestyle, such as plastic waste disposal, CO2 emission, e-waste, among others, which need to be addressed accordingly. The reuse provided, well-structured within the context of circular chemistry, can bring benefits in all spheres: social, environmental and economic. Thus, the purpose of this revision is to present CE and CC as the pillars for a sustainable development, bringing discussions about: CE and CC systems; sustainable chemistry; and chemistry 4.0, which embeds digitization, sustainability, and circular economy in industrial chemical processes. Through the knowledge of chemistry, both CC and CE can contribute with innovative methods and processes which maximize benefits, eliminating, or, at least, reducing adverse impacts, thus contributing to construct a mutually beneficial relationship between science and society, its surroundings, and the environment. Therefore, implementing this new model is an opportunity that challenges the human imagination in building a better world.

Abstract Wine industry by-product (WIB) is rich in bioactive compounds, including phenolics. Since root-knot nematodes are suppressed by phenolic compounds, soil amendment with WIB may control these pathogens. We evaluated the effect of wine industry by-product (WIB) on the management of Meloidogyne javanica in tomato plants in greenhouse. In the first study, potted soil was amended with 0, 5, 10, 15, 20 25 and 30 g of WIB per kg of soil. Increasing doses of WIB increased plant development. Nematode population was reduced by WIB, especially at the dose of 30 g kg-1 of soil. In the second study, a split-root experiment was designed to assess if soil amendment with WIB (30 g kg-1 of soil) induces resistance on tomato against M. javanica. WIB does not induce tomato resistance against M. javanica. This residue controls the nematode by direct contact.

Resumen El subproducto de la industria vitivinícola (SIV) es rico en compuestos bioactivos, incluidos los fenólicos. Dado que los nematodos del nudo de la raíz son suprimidos por compuestos fenólicos, la enmienda del suelo con SIV puede controlar estos patógenos. Evaluamos el efecto del subproducto de la industria vitivinícola (SIV) en el manejo de Meloidogyne javanica en plantas de tomate en invernadero. En el primer estudio, el suelo en macetas se enmendó con 0, 5, 10, 15, 20, 25 o 30 g de SIV por kg. Las dosis crecientes de SIV incrementaron el desarrollo de la planta. El SIV redujo la población de nematodos, especialmente a la dosis de 30 g kg-1 de suelo. En el segundo estudio, se diseñó un experimento de raíces divididas para evaluar si la enmienda del suelo con SIV (30 g kg-1 de suelo) induce resistencia en el tomate contra M. javanica. El SIV no induce resistencia en el tomate contra M. javanica. Este residuo controla el nematodo por contacto directo.

RESUMO Contexto: Não encontramos na literatura estudos sobre a qualidade de vida em pacientes com acalásia chagásica especificamente. Objetivo: Comparar a qualidade de vida de pacientes com acalásia chagásica e a da população em geral. Também, correlacionar a qualidade de vida nestes pacientes com fatores clínicos que possam afetá-la. Métodos: Estudamos 60 pacientes com acalásia chagásica e 50 controles. Todos os pacientes foram submetidos à manometria esofágica para diagnóstico de acalásia e esofagograma técnica padrão para determinar o grau do megaesôfago. Usamos 3 questionários: 1) clínico: foram coletados os seguintes dados: demográficos, história clínica, índice de massa corporal, presença de seis sintomas esofágicos (definimos Escore de Sintomas Esofágicos como o número de sintomas relatados pelos pacientes), duração da disfagia; 2) avaliação sócio-econômico-cultural: sete questões sobre as condições sócio-econômico-culturais foram perguntadas para pacientes e controles; 3) qualidade de vida: foi avaliada pelo questionário SF-36, versão validada para o português-Brasil (licença QM020039). Este é um questionário genérico que mede a qualidade de vida em oito domínios: 3a) quatro físicos: capacidade funcional, aspectos físicos, dor corporal, estado geral de saúde; 3b) quatro mentais: vitalidade, aspectos sociais, aspectos emocionais, saúde mental. Estes oito domínios podem ser compilados em dois escores: Sumário dos Escores Físicos e Sumário dos Escores Mentais. Na análise de fatores clínicos que pudessem afetar a qualidade de vida dos pacientes, avaliamos: escores de sintomas esofágicos, duração da disfagia, índice de massa corporal, graus de megaesôfago e presença/ausência de megacólon. Resultados: Os dois grupos (pacientes e controles) apresentaram semelhantes idade, gênero, história médica e condições socioeconômico-culturais (P>0,05). Todos os pacientes tinham disfagia e megaesôfago. Com relação à qualidade de vida, pacientes com acalásia chagásica apresentaram valores significativamente menores do que os controles em todos os domínios do questionário SF-36 (domínios físicos: P<0,002; domínios mentais: P<0,0027). Os Sumários dos Escores Físicos e Mentais também foram significativamente menores em pacientes do que nos controles (P<0.0062). A análise dos fatores clínicos que poderiam afetar a qualidade de vida nos pacientes mostrou que o Sumário dos Escores Físicos se correlaciona negativamente com o Escores Dos Sintomas Esofágicos (P=0,0011) e positivamente com o índice de massa corporal (P=0,02). Não observamos qualquer outra correlação. Conclusão: Pacientes com Acalásia Chagásica têm pior qualidade de vida que a população em geral, em todos os domínios físicos e mentais. Pacientes que relataram mais sintomas apresentaram pior qualidade de vida nos domínios físicos. Pacientes com valores maiores de índice de massa corporal apresentaram melhor qualidade de vida nos domínios físicos.

ABSTRACT Background: No study has focused on Health-Related Quality of Life (HRQoL) for Chagas Achalasia patients. Objective: To compare HRQoL between Chagas Achalasia patients and the general population; and to correlate HRQoL with clinical factors that can affect it. Methods: Sixty Chagas Achalasia patients and 50 controls were evaluated. All patients underwent esophageal manometry for the diagnosis of achalasia and esophagogram to determine the grade of megaesophagus. Three questionnaires were used: 1) clinical: the following data were collected: demographic, medical history, body mass index, occurrence of six esophageal symptoms (Esophageal Symptom Score: number of symptoms reported by patients), duration of dysphagia; 2) socio-economic-cultural status evaluation: patients and controls answered seven questions about their socio-economic-cultural conditions; 3) HRQoL: the validated Brazilian-Portuguese version of the Short-form Health Survey (SF-36) questionnaire (license QM020039) was used. It measures health in eight domains: 3a) four physical: physical functioning, role limitations relating to physical health, bodily pain, and general health perception; 3b) four mental: vitality, social functioning, role limitations relating to emotional health, and mental health. These domains can be summarized into Physical and Mental Summary scores. We analyzed correlations between SF-36 Physical/Mental Summary Component scores and the following clinical factors: Esophageal Symptom Score, duration of dysphagia, body mass index, grades of megaesophagus (defined by the esophagogram) and presence/absence of megacolon (defined by opaque enema). Results: Patients and controls had similar age, gender, medical history, and socio-economic-cultural lifestyles (P>0.05). All patients had dysphagia and megaesophagus. SF-36 scores were significantly lower in Chagas Achalasia patients than controls for all eight domains (physicals: P<0.002; mentals: P<0.0027). The Physical and Mental Summary Component scores were also lower in Chagas Achalasia patients than controls (P<0.0062). For patients, the Physical Summary score was negatively correlated to Esophageal Symptom Score (P=0.0011) and positively correlated to body mass index (P=0.02). No other correlations were found. Conclusion: Chagas Achalasia patients have an impaired HRQoL in all physical and mental domains. Patients reporting more symptoms had worse physical domains. Patients with higher body mass index had better physical domains.

ABSTRACT Among the fuel sources used nowadays, biofuels stand out for being renewable and biodegradable. In this sense, this work aimed to evaluate the performance and smoke opacity of an agricultural tractor in soil tillage activities, depending on the biodiesel blends and the engine rotation. Were used six blends of soy (S) and murumuru (M) biodiesel and seven engine rotation speeds. The results showed a directly proportional relationship between the drawbar power and the engine rotation decrease. Regarding hourly volumetric and weighted consumption, both presented the same behavior: the lowest consumptions were reached when using the two highest proportions of murumuru biodiesel, yet the highest specific consumption was obtained when using the 90M10S blend. Furthermore, the lowest opacity was emitted when the tractor was fueled with the three blends having the highest proportions of murumuru biodiesel. Blends with more than 80% of murumuru biodiesel promote lower fuel consumption than blends with a higher concentration of soy biodiesel. Regardless of the biodiesel blend, the traction force at the drawbar is directly proportional to an increase in the engine rotation speed. In smoke opacity, mixtures with more than 70% murumuru biodiesel promote less opacity than mixtures with a higher concentration of soy biodiesel.

RESUMO Antecedentes: As ataxias espinocerebelares (SCA) são um grupo de doenças neurodegenerativas caracterizadas pela deterioração do equilíbrio e da funcionalidade, que tende a acompanhar a progressão da doença. Não existe uma ligação estabelecida entre os marcadores clínicos formais de gravidade e escores funcionais e de equilíbrio que possam orientar as equipes de reabilitação. Objetivo: Avaliar a relação entre escalas funcionais e de gravidade da ataxia, buscando identificar pontos de corte para a perda funcional relacionados aos escores de gravidade e aos patamares de Risco de Quedas. Métodos: Uma amostra consecutiva de 89 pacientes com diagnóstico molecular de SCA (31-SCA2 e 58-SCA3) foram avaliados para funcionalidade MIF-AVDs (Medida de independência funcional-Atividades da vida diária) e Lawton-AIVDs (Atividades instrumentais da vida diária), equilíbrio (EEB-escala de Equilíbrio de Berg), e gravidade da ataxia (SARA-escala para avaliação e graduação de ataxia). Resultados: Os principais pontos de corte de deficiência foram: com 12 pontos no SARA começa a necessidade de supervisão para MIF-AVDs e com 14 pontos no SARA começa a necessidade de supervisão para Lawton-AIVDs. Os primeiros itens a necessitar de assistência foram “expressão” e “compras”, respectivamente. Com 20 pontos no SARA os pacientes eram dependentes em todos os itens MIF/LAWTON. O item com maior impacto na discriminação entre dependentes e independentes foi “meio de transporte” na Lawton e o domínio “locomoção” na MIF. O escore médio no SARA foi de 9,9 pontos para pacientes classificados com baixo risco na EEB, 17,4 para médio risco e 25,2 para alto risco. Conclusões: A análise da correlação entre a gravidade da ataxia e as escalas funcionais pode ser um importante guia no entendimento da progressão da dependência funcional em indivíduos com SCA.

ABSTRACT Background: Spinocerebellar ataxias (SCAs) are a group of neurodegenerative diseases characterized by deterioration of balance and functionality that tends to follow disease progression. There is no established link between formal clinical markers for severity and functional/balance scores that could guide rehabilitation teams. Objective: To evaluate the relationship between functional scales and ataxia severity in order to identify cutoff landmarks for functional loss and estimate the mean SARA (Scale for Assessment and Rating of Ataxia) score for the risk ratings for falls on the BBS (Berg Balance Scale). Methods: Consecutive patients with a molecular diagnosis of SCA (total 89: 31 with SCA2 and 58 with SCA3) were assessed for functionality FIM-ADL (Functional Independence Measure-activities of daily living and Lawton-IADL (instrumental activities of daily living), balance (BBS) and disease severity (SARA). Results: The main disability cutoff landmarks were that the need for supervision for FIM-ADL starts with 12 points on SARA and the need for supervision for Lawton-IADL starts with 14 points on SARA. The first items to require assistance were “expression” and “shopping”, respectively. At 20 points on SARA, patients were dependent on all FIM and Lawton items. The item with the greatest impact on distinguishing dependents from independents was “means of transport” in Lawton-IADL and the domain “locomotion” in FIM-ADL. The mean SARA score for patients classified as low risk in the BBS was 9.9 points, and it was 17.4 for medium risk and 25.2 for high risk. Conclusions: Analysis on the correlation between the severity of ataxia and functional scales can form an important guide for understanding the progression of functional dependence among individuals with SCAs.

RESUMO Perdas na produção agrícola, causadas principalmente por temperaturas extremas, chuvas e secas, têm exigido a adaptação da agricultura brasileira às mudanças climáticas em curso. Objetivou-se avaliar, por meio de uma revisão integrativa, os efeitos das práticas agrícolas estabelecidas por duas políticas públicas brasileiras (Plano ABC e Planaveg) na resiliência e adaptação dos sistemas agrícolas do país, considerando-se os efeitos no clima local e eventos extremos. Todas as coleções da biblioteca da Embrapa foram utilizadas como fontes principais e o Google Acadêmico como fonte secundária. A busca incluiu publicações de 1998 a abril de 2022 e resultou em 334 dados, extraídos de 51 referências, abrangendo pelo menos um fator e uma prática. A revisão mostrou que as práticas propostas podem contribuir para a resiliência e adaptação dos setores agropecuário e forestal do Brasil às mudanças climáticas nas principais regiões produtoras. Estudos indicam que a incorporação de componente arbóreo nos sistemas de produção pode proporcionar um ambiente mais resiliente a secas, aumento da umidade do ar, redução do impacto da temperatura e dos riscos de incêndio, entre outros benefícios. A adoção das práticas do Plano ABC e Planaveg pelo setor agropecuário é uma opção viável, estratégica e bem alinhada com uma economia de baixo carbono, ao mesmo tempo em que aumenta a resiliência aos impactos presentes e futuros das mudanças climáticas.

ABSTRACT Losses in agricultural production, mainly caused by extreme temperature, rainfall and drought, have demanded the adaptation of the Brazilian agriculture to the ongoing climate change. This study aimed to evaluate, through an integrative review, the effects of agricultural practices established by two Brazilian public policies (ABC Plan and Planaveg) on the resilience and adaptation of the country’s agricultural systems, considering the effects on local climate and extreme events. All the Embrapa library collections were used as main sources, and the Google Scholar was used as a secondary source. The search included publications from 1998 to April 2022 and resulted in 334 data, extracted from 51 references, covering at least one factor and one practice. The review showed that the proposed practices may contribute to the resilience and adaptation of the Brazilian agricultural and forestry sectors to climate change in the main production regions. Studies have indicated that the incorporation of the arboreal component into production systems may provide an environment more resilient to droughts, increased air humidity, reduced temperature impact and reduced fire risks, among other benefits. The adoption of the ABC Plan and Planaveg practices by the agricultural sector is an option feasible, strategic and well-aligned with a low-carbon economy, while it increases the resilience to present and future climate change impacts.

ABSTRACT The growing demand for clean energy aimed at reducing greenhouse gas emissions associated with the oil crises has encouraged the search for biofuels, among which biodiesel has stood out in the gradual replacement of diesel. This study aimed to evaluate the performance of an agricultural tractor fueled with four types of biodiesels (peanut, sunflower, soybean, and waste frying oil) added to diesel at five proportions (0, 25, 50, 75, and 100% biodiesel, that is, B0, B25, B50, B75, and B100, respectively). The experiment was carried out at the Laboratory of Biofuel and Machinery Testing at FCAV–UNESP. A Valtra BM100 4×2 FWD tractor with a power of 74 kW (100 hp) was used. The drawbar pull force (DF), displacement velocity (V), drawbar power (DP), volumetric fuel consumption (VC), weight fuel consumption (WC), and specific fuel consumption (SC) were studied. The factors did not influence DF, V, and DP. The proportion factor influenced (p<0.01) the volumetric fuel consumption, in which diesel S50 was 14% more efficient than B100. Weight fuel consumption was influenced by the type of biodiesel in the blend. Diesel had the lowest specific fuel consumption (328 g kW h−1). The biodiesel fraction showed a direct relationship with the consumption parameters, with sunflower showing the lowest WC value in the B75 and B100 blends.

RESUMO Antecedentes: A predisposição genética para a esclerose múltipla (EM) está associada a alelos HLA, principalmente o HLA-DRB1*15:01. Objetivo: Identificar associações entre lesões na ressonância magnética e características genéticas em uma coorte brasileira de pacientes com EM. Métodos: Estudamos retrospectivamente os dados de 95 pacientes consecutivos com EM. Dois observadores independentes que desconheciam os dados clínicos identificaram “black holes” e lesões realçadas pelo contraste nas sequências de ressonância magnética T1 e contaram e mediram as lesões nas sequências T2 e FLAIR (fluid attenuated inversion recovery). Os casos foram classificados de acordo com tamanho, número e volume da lesão. Os alelos HLA-DRB1, HLA-DQB1 e HLA-DQA1 e os polimorfismos de nucleotídeo único rs4774, rs3087456, rs6897932, rs731236 e rs1033182 foram identificados por amplificação de reação em cadeia da polimerase com iniciadores específicos de sequência usando o kit One Lambda Inc., Canoga Park, CA, EUA. Resultados: Os pacientes com alelo HLA-DQA1*04:01 apresentaram carga de lesão (ajustada para idade, sexo e duração da EM) acima da mediana em comparação com outros pacientes com demais alelos HLA-DQA1 (p=0,02). Não houve diferenças entre todos os outros alelos HLA e polimorfismos de nucleotídeo único e carga lesional. Conclusões: A correlação do alelo HLA-DQA1*04:01 com maior carga de lesão nas sequências de RM em T2 sugere que a presença desse alelo pode estar associada ao risco de maior gravidade da EM.

ABSTRACT Background: The genetic predisposition to multiple sclerosis (MS) is associated with HLA alleles, especially HLA-DRB1*15:01. Objective: To identify associations between findings in magnetic resonance imaging (MRI) and genetic features in a Brazilian cohort of patients with MS. Methods: We retrospectively studied data from 95 consecutive patients with MS. Two independent observers who were blinded to the clinical data identified black holes and enhanced lesions on T1 MRI sequences, and counted and measured contrast-enhanced lesions on T2 and Flair (fluid attenuation inversion recovery) sequences. Cases were classified according to lesion size, number, and volume. The HLA-DRB1, HLA-DQB1, and HLA-DQA1 alleles, and the rs4774, rs3087456, rs6897932, rs731236, and rs1033182 single nucleotide polymorphisms were identified by polymerase chain reaction amplification with sequence-specific primers using the One Lambda Inc. Kit, Canoga Park, CA, USA. Results: Patients with the HLA-DQA1*04:01 allele had lesion load (adjusted for age, sex, and MS duration) above median compared with patients with other HLA-DQA1 alleles (p=0.02). There were no differences among all the other HLA alleles and single nucleotide polymorphisms and lesion load. Conclusions: The correlation of the HLA-DQA1*04:01 allele with a higher lesion load on T2/Flair MRI sequences suggests that the presence of this allele is associated with the risk of greater MS severity.

RESUMO Os canabinoides compreendem os endocanabinoides, fitocanabinoides e os canabinoides sintéticos e desempenham ações no sistema nervoso central e periférico. Uma quantidade enorme de publicações tem sido lançada nos últimos anos, embora a cannabis seja conhecida por milênios. Os Departamentos Científicos da Academia Brasileira de Neurologia descreveram as evidências do uso médico em suas áreas. A literatura está em constantes mudanças e possíveis novas evidências podem surgir nos próximos dias ou meses. A prescrição dessas substâncias deve ser discutida com os pacientes e suas famílias, com conhecimento sobre eventos adversos e sua eficácia.

ABSTRACT Cannabinoids comprehend endocannabinoids, phytocannabinoids, and synthetic cannabinoids, with actions both in the central and peripherical nervous systems. A considerable amount of publications have been made in recent years, although cannabis has been known for over a thousand years. Scientific Departments from the Brazilian Academy of Neurology described evidence for medical use in their areas. Literature is constantly changing, and possible new evidence can emerge in the next days or months. Prescription of these substances must be discussed with patients and their families, with knowledge about adverse events and their efficacy.

RESUMO Nas últimas décadas, o setor de produtos de resina no Brasil está demonstrando uma perspectiva de demanda crescente para os produtores de goma de resina, o que exige avanços na parte técnica dos processos de extração e purificação. Este trabalho teve como objetivo analisar, através de técnicas de planejamento experimental, os processos de lavagem e destilação da oleorresina de Pinus elliottii. A resina natural foi coletada na região costeira do estado do Rio Grande do Sul, Brasil. Os resultados da etapa de lavagem revelaram que as interações lineares de segunda ordem foi o modelo empírico mais adequado para este estudo. Portanto, o teste ideal foi determinado com os seguintes fatores: temperatura de 50ºC, tempo de 20 min e 20% de terebentina utilizada para a diluição. Para o processo de destilação, o melhor modelo foi o linear sem interações, considerando a resposta do Valor Monetário (Real - R$) por 100 g de resina processada. Assim, determinou-se que a região ótima obteve os seguintes fatores: temperatura entre 156 e 170ºC e tempo entre 61 e 100 minutos. Portanto, o uso de técnicas de planejamento experimental permitiu propor ao produtor algumas alternativas no processamento de resina natural, o que consequentemente causou o aumento do valor agregado ao produto comercializado.

ABSTRACT In the last decades, the resin product sector in Brazil is demonstrating a growing demand perspective for resin gum producers, what requires advances in the technical part of the extraction and purification processes. This work aimed to analyze, through experimental design techniques, the washing and distillation processes of the Pinus elliottii oleoresin. The natural resin was collected in the coastal region of Rio Grande do Sul state, Brazil. The results of the washing step revealed that the linear with second-order interactions was the empirical model that best suited for this study. Therefore, the optimal test was determined with the following factors: temperature of 50ºC, time of 20 min, and 20% turpentine used for dilution. For the distillation process, the best model was the linear without interactions taking into account the Monetary Value (Real - R$) response per 100 g of processed resin. Thus, it was determined that the optimum region obtained the following factors: temperature between 156 and 170 ºC and time between 61 and 100 min. Therefore, the use of experimental design techniques enabled to propose some alternatives on the processing of natural resin to the producer, what consequently caused the increase in its added value to the marketed product.

Resumo Objetivo Analisar a concordância, em relação ao percentil 90, das medidas ultrassonográficas da circunferência abdominal (CA) e peso fetal estimado (PFE), entre as tabelas da Organização Mundial de Saúde (OMS) e do International Fetal and Newborn Growth Consortium for the 21st Century integrowth-21st, bem como em relação ao peso ao nascer em fetos/recém-nascidos de mães diabéticas. Métodos Estudo retrospectivo com dados de prontuários de 171 gestantes diabéticas, com gestações únicas, seguidas entre Janeiro de 2017 e Junho de 2018. Foram analisados dados da CA e do PFE na admissão (a partir de 22 semanas) e no pré-parto (até 3 semanas). Essas medidas foram classificadas em relação ao percentil 90. O coeficiente Kappa foi utilizado para analisar a concordância entre as tabelas da OMS e Intergrowth-21st, assim como, por tabela de referência, entre as medidas e o peso ao nascer. Resultados O estudo da OMS relatou 21,6% dos recém nascidos grandes para a idade gestacional (GIG) enquanto que o estudo do intergrowth-21st relatou 32,2%. Ambas as tabelas tiveram fortes concordâncias na avaliação da CA inicial e final e PFE inicial (Kappa= 0,66, 0,72 e 0,63, respectivamente) e concordância quase perfeita em relação ao PFE final (Kappa= 0,91).Emrelação ao peso ao nascer, asmelhores concordâncias foram encontradas para aCAinicial (OMS: Kappa= 0,35; intergrowth-21st: Kappa= 0,42) e como PFE final (OMS: Kappa = 0,33; intergrowth-21st: Kappa= 0,35). Conclusão A CA inicial e o PFE final foram os parâmetros de melhor concordância em relação à classificação do peso ao nascer. As tabelas da OMS e intergrowth-21st mostraram alta concordância na classificação das medidas ultrassonográficas em relação ao percentil 90. Estudos são necessários para confirmar se alguma dessas tabelas é superior na previsão de resultados negativos a curto e longo prazo no grupo GIG.

Abstract Objective To analyze the agreement, in relation to the 90th percentile, of ultrasound measurements of abdominal circumference (AC) and estimated fetal weight (EFW), between the World Health Organization (WHO) and the International Fetal and Newborn Growth Consortium for the 21st Century (intergrowth-21st) tables, as well as regarding birth weight in fetuses/newborns of diabetic mothers. Methods Retrospective study with data from medical records of 171 diabetic pregnant women, single pregnancies, followed between January 2017 and June 2018. Abdominal circumference and EFW data at admission (from 22 weeks) and predelivery (up to 3 weeks) were analyzed. These measures were classified in relation to the 90th percentile. The Kappa coefficient was used to analyze the agreement of these ultrasound variables between the WHO and intergrowth-21st tables, as well as, by reference table, these measurements and birth weight. Results The WHO study reported 21.6% large-for-gestational-age (LGA) newborns while the intergrowth-21st reported 32.2%. Both tables had strong concordances in the assessment of initial AC, final AC, and initial EFW (Kappa = 0.66, 0.72 and 0.63, respectively) and almost perfect concordance in relation to final EFW (Kappa = 0.91). Regarding birth weight, the best concordances were found for initial AC (WHO: Kappa = 0.35; intergrowth-21st: Kappa= 0.42) and with the final EFW (WHO: Kappa = 0.33; intergrowth- 21st: Kappa = 0.35). Conclusion The initial AC and final EFW were the parameters of best agreement regarding birth weight classification. The WHO and intergrowth-21st tables showed high agreement in the classification of ultrasound measurements in relation to the 90th
