Abstract This article presents a formulation for the optimization problem that minimizes the CO2 emission of pile caps with variations of geometry and pile position. The problem is defined by the design variables: concrete pile cap dimensions, rebar ratio, concrete compressive strength, the number of piles, the diameter, and length. The environmental impact was chosen as the objective function, taking CO2 emission as the main parameter. The design procedure was based on the ABNT NBR 6118:2014 (2014), and by the formulation proposed by Blévot & Frémy (1967). Also, the soil structure interaction between the cap and the piles was considered in the optimization problem. The problem was implemented using MATLAB (2016) and solved via a Genetic Algorithm native to the program. Results obtained from numerical examples were compared with structural designs solutions located in the Grande Vitória metropolitan area, Espírito Santo, Brazil and validated with a commercial software. The analyses indicate that design optimizations of pile caps considering the compressive strength of concrete, the diameter and length of piles and the optimal geometry of the pile caps may lead to significant reductions of material consumption, and consequently, a reduction of environmental impacts.

Resumo Os microRNAs (miRNAs) são reconhecidos como biomarcadores do diabetes mellitus tipo 2 (DM2), úteis para a compreensão do metabolismo da doença, e possuem grande potencial como alvos terapêuticos. O aumento da expressão de BDNF e IGF1 está altamente envolvido nos benefícios as vias de insulina e glicose, porém, são regulados negativamente em condições de resistência à insulina, enquanto seu aumento de expressão está correlacionado com a melhora do metabolismo da glicose e da insulina. Estudos sugerem a regulação desses genes por microRNA em vários contextos diferentes, proporcionando uma nova abordagem de investigação para compreender o metabolismo do DM2 e revelar potenciais alvos terapêuticos. No presente estudo, investigamos em diferentes modelos animais (humanos, ratos e camundongos) miRNAs que têm como alvo BDNF e IGF1 em tecido muscular esquelético com condições fisiológicas de DM2. As análises foram realizadas utilizando ferramentas de bioinformática e bancos de dados para predição de miRNA, homologia molecular, validação experimental de interações, expressão na condição fisiológica estudada e interação em rede. Os resultados mostraram três candidatos a miRNAs para IGF1 (miR-29a, miR-29b e miR-29c) e um para BDNF (miR-206). As avaliações experimentais e a busca pela expressão no músculo esquelético de indivíduos com DM2 confirmaram a interação prevista entre miRNA-mRNA para miR-29b e miR-206 através de modelos humanos, ratos e camundongos. Essa interação foi reafirmada em múltiplas análises de rede. Em conclusão, nossos resultados mostram a relação de regulação entre miR-29b e miR-206 com os genes investigados, em diversos tecidos, sugerindo um padrão de inibição. Contudo, esses dados mostram um grande número de possíveis processos fisiológicos de interação para perspectivas biotecnológicas.

Abstract microRNAs (miRNAs) are recognized as diabetes mellitus type 2 (T2DM) biomarkers useful for disease metabolism comprehension and have great potential as therapeutics targets. BDNF and IGF1 increased expression are highly involved in the benefits of insulin and glucose paths, however, they are down-regulated in insulin resistance conditions, while their expression increase is correlated to the improvement of glucose and insulin metabolism. Studies suggest the microRNA regulation of these genes in several different contexts, providing a novel investigation approach for comprehending T2DM metabolism and revealing potential therapeutic targets. In the present study, we investigate in different animal models (human, rat, and mouse) miRNAs that target BDNF and IGF1 in skeletal muscle tissue with T2DM physiological conditions. Bioinformatics tools and databases were used to miRNA prediction, molecular homology, experimental validation of interactions, expression in the studied physiological condition, and network interaction. The findings showed three miRNAs candidates for IGF1(miR-29a, miR-29b, and miR-29c) and one for BDNF (miR-206). The experimental evaluations and the search for the expression in skeletal muscle from T2DM subjects confirmed the predicted interaction between miRNA-mRNA for miR-29b and miR-206 through human, rat, and mouse models. This interaction was reaffirmed in multiple network analyses. In conclusion, our results show the regulation relationship between miR-29b and miR-206 with the investigated genes, in several tissues, suggesting an inhibition pattern. Nevertheless, these data show a large number of possible interaction physiological processes, for future biotechnological prospects.

Resumo A busca por herbicidas mais amigáveis ao meio ambiente, visando o controle de pragas agrícolas, aliado a uma menor nocividade à saúde humana e ao meio ambiente tem crescido. Uma alternativa utilizada pelos pesquisadores é a aplicação de produtos do metabolismo secundário de plantas, que são investigados em virtude do seu potencial bioativo. Assim, espécies pertencentes à família Myrtaceae são potenciais nestes estudos, uma vez que esta família é reconhecida por possuir alta atividade biológica. Uma espécie pertencente a este gênero é Psidium cattleyanum, que possui efeito medicinal e seus frutos são utilizados na alimentação humana. Assim, o objetivo desta pesquisa foi avaliar e comparar a fitocitogenotoxicidade de extratos foliares aquosos e etanólicos da espécie P. cattleyanum, a partir de bioensaios vegetais, bem como identificar as principais classes de compostos presentes nos extratos. Para isso, os extratos foram preparados e caracterizados e foram realizados testes biológicos avaliando, em sementes e plântulas de alface e sorgo, as variáveis: porcentagem de germinação, índice de velocidade de germinação, crescimento radicular e crescimento aéreo; em células meristemáticas de alface foram avaliadas as variáveis: fases mitóticas, índice mitótico, alterações nucleares e alterações cromossômicas. Flavonas, flavononas, flavonóis, flavononóis, flavonóides, alcalóides, resinas, xantonas e glicosídeo de antraquinona foram caracterizados no extrato etanólico. Ambos os extratos avaliados, na maior concentração, inibiram o desenvolvimento inicial da planta. Todos os tratamentos causaram alterações nas fases mitóticas e inibiram o índice mitótico. Além disso, os tratamentos promoveram aumento de alterações nucleares e cromossômicas. O mecanismo de ação apresentado foi aneugênico, clastogênico e epigenético. O extrato etanólico foi mais citotóxico, pois teve efeito mais expressivo em menor concentração. Apesar da citotoxicidade dos extratos em estudo, eles promoveram alterações em níveis inferiores ao controle positivo glifosato.

Abstract The search for more environmental friendly herbicides, aiming at the control of agricultural pests, combinated with less harmfulness to human health and the environment has grown. An alternative used by researchers is the application of products of secondary plant metabolism, which are investigated due to their potential bioactivities. Thus, species belonging to the Myrtaceae family are potential in these studies, since this family is recognized for having high biological activity. A species belonging to this genus is Psidium cattleyanum, which has a medicinal effect and its fruits are used in human food. Thus, the objective of this research was to evaluate and compare the phyto-cyto-genotoxicity of aqueous and ethanolic leaf extracts of the specie P. cattleyanum, from plant bioassays, as well as to identify the main classes of compounds present in the extracts. For this, the extracts were prepared, characterized and biological tests were carried out by evaluating, in seeds and seedlings of lettuce and sorghum, the variables: percentage of germination, germination speed index, root growth and aerial growth; and in meristematic lettuce cells the variables: mitotic phases, mitotic index, nuclear alterations and chromosomal alterations. Flavones, flavonones, flavonols, flavononols, flavonoids, alkaloids, resins, xanthones and anthraquinone glycoside were characterized in the ethanolic extract. Both evaluated extracts, in the highest concentration, inhibited the initial plant development. All treatments caused alterations in the mitotic phases and inhibited mitotic index. In addition, the treatments promoted an increase in nuclear and chromosomal alterations. The mechanism of action presented was aneugenic, clastogenic and determined in epigenetic alterations. The ethanolic extract was more cytotoxic, since it had a more expressive effect at a lower concentration. Despite the cytotoxicity of the extracts under study, they promoted alterations at lower levels than the glyphosate positive control.

Resumo A lagarta-do-cartucho (Spodoptera frugiperda) é a principal espécie que causa danos à cultura do milho no Brasil. Na perspectiva de estudar alternativas de controle desta praga que preservem os inimigos naturais, o objetivo desta pesquisa foi avaliar a eficiência inseticida dos óleos essenciais de Vanillosmopsis arborea e Lippia microphylla sobre S. frugiperda e verificar a seletividade ao predador Euborellia annulipes. Os bioensaios foram realizados no Laboratório de Entomologia Agropecuária da Universidade Federal da Paraíba, utilizando insetos, de 3º instar de S. frugiperda e E. annulipes, oriundos de criação massal no próprio laboratório. As diluições dos óleos foram realizadas em Tween® 80 nas concentrações de 0, 100, 150 e 200 mg mL-1. 1,0 μL de cada diluição foi aplicado na região protorácica dos insetos. A mortalidade de S. frugiperda foi verificada pelo contato tópico do óleo de V. arborea com LC10 = 74,3 mg mL-1 e LC50 = 172,86 mg mL-1, para L. microphyla, LC10 = 51,26 mg mL-1 e LC50 = 104,52 mg mL-1. As concentrações letais observadas para E. annulipes foram V. arborea LC10 = 71,3 mg mL-1 e LC50 = 160,2 mg mL-1. Enquanto L. microphyla, foram LC10 = 50,3 mg mL-1 e LC50 = 134,67 mg mL-1. Os óleos essenciais de V. arborea e L. microphylla são eficientes no controle de S. frugiperda, mas não são seletivos ao predador E. Annulipes.

Abstract Fall armyworm (Spodoptera frugiperda) is the main species that causes damage to the maize crop in Brazil. In the perspective of studying alternatives of control of this pest that preserve the natural enemies, the aim of this research was to evaluate the insecticidal efficiency of the essential oils of Vanillosmopsis arborea and Lippia microphylla on S. frugiperda and verify the selectivity to the predator Euborellia annulipes. The bioassays were carried out in the Agricultural Entomology Laboratory of the Federal University of Paraiba, using insects, from 3rd instar of S. frugiperda and E. annulipes, originating from mass rearing in the laboratory itself. Dilutions of the oils were performed in Tween® 80 at concentrations of 0, 100, 150 and 200 mg mL-1. 1.0 μL from each dilution was applied to the prothoracic region of the insects. The S. frugiperda mortality was verified by topical contact of V. arborea oil with LC10 = 74.3 mg mL-1 and LC50 = 172.86 mg mL-1, for L. microphyla, LC10 = 51.26 mg mL-1 and LC50 = 104.52 mg mL-1. The observed lethal concentrations for E. annulipes were V. arborea LC10 = 71.3 mg mL-1 and LC50 = 160.2 mg mL-1. While L. microphyla, were LC10 = 50.3 mg mL-1 and LC50 = 134.67 mg mL-1. The essential oils of V. arborea and L. microphylla are efficient in the control of S. frugiperda, but are not selective to the predator E. Annulipes.

Space-time analysis, if considered, may promote the improvement of surveillance and control actions of visceral leishmaniosis.

Resumo Nematoides entomopatogênicos (NEP) das famílias Heterorhabditidae e Steinernematidae são amplamente utilizados no controle de insetos-pragas. No Brasil, os estudos relacionados a caracterização e identificação destes entomopatógenos são recentes e escassos. Nesse sentido, o objetivo deste estudo foi isolar NEP de amostras de solos coletadas em diferentes áreas no estado do Paraná, Brasil. Um isolado Heterorhabditis (UEL 08) detectado em amostra de solo em área de pastagem cultivada com braquiária, localizada em Londrina, Paraná, Brasil (23º34´311´´S, 050º58´298´´W), utilizando o método de “inseto-isca” com lagartas de Galleria mellonella. Para a identificação foram realizados estudos de morfometria e identificação molecular a partir da amplificação da região ITS. Algumas diferenças foram encontradas em termos de morfometria em comparação com a descrição original, entretanto, os dados moleculares demonstraram que a sequência obtida para o isolado UEL 08 é idêntica à sequência de referência de H. amazonensis (DQ665222), com a qual apresentou 100% de similaridade. Os estudos das características biológicas de H. amazonensis (UEL 08) revelaram que o isolado tem dois ciclos de vida distintos, um curto (216 h) e outro longo (288 h), sendo que ocorrem duas gerações em ambos os ciclos. O isolado UEL 08 H. amazonensis foi patogénico e virulento sobre os três hospedeiros avaliados. Notadamente, as larvas de G. mellonella e Alphitobius diaperinus foram consideradas mais susceptíveis do que os adultos do percevejo Dichelops (Diacereus) melacanthus, com percentagens de mortalidade de 100%, 85% e 46% de mortalidade, respectivamente. O ensaio de produção in vivo revelou um rendimento médio diário de 3,4 × 103 juvenis infectantes/g de larva hospedeira.

Abstract Entomopathogenic nematodes (EPNs) from Heterorhabditidae and Steinernematidae families are extensively used to control insect pests. In Brazil, however, relatively few studies have identified and characterized these entomopathogens. The objective of this study was to identify and characterize an EPN isolate obtained from soil samples collected in the state of Paraná, Brazil. An isolate (UEL 08) of Heterorhabditis was detected in a soil sample collected from a pasture area cultivated with Brachiaria grass in Londrina, state of Paraná, Brazil (23°34ʹ311ʹʹS, 050°58ʹ298ʹʹW), using the insect-baiting technique with Galleria mellonella larvae as hosts. The nematode was identified through morphometric studies and molecular analyses based on amplification of the rDNA ITS region. Although we identified certain morphometric differences compared with the original description, the molecular data indicated that the ITS sequence obtained for the UEL 08 isolate is identical to the reference sequence of H. amazonensis (DQ665222) and presented 100% similarity. Thus, the findings of our morphological and molecular studies confirmed that the isolated nematode is H. amazonensis, which is the first time this species has been registered in Paraná. Study of the biological characteristics of H. amazonensis (UEL 08) revealed that the isolate has two distinct life cycles – one short (216 h) and the other long (288 h) – and produces two generations in both cycles. We observed that H. amazonensis (UEL 8) was pathogenic and virulent to the three evaluated hosts, although with different virulence against these hosts. The larvae of G. mellonella and Alphitobius diaperinus were more susceptible than adult Dichelops (Diacereus) melacanthus, with 100%, 85%, and 46% mortality, respectively. Furthermore, an in vivo production assay revealed a mean daily yield of 3.4 × 103 infective juveniles/g host larvae.

Abstract Objective Evaluate autonomic function and low-grade inflammation and characterize the correlation between these variables in schoolchildren with obesity living in the Brazilian northeast region. Methods 84 children with obesity and 41 with normal weight were included in this cross-sectional study. Anthropometry, body composition, blood pressure (BP), inflammatory biomarkers, and heart rate variability (HRV) indexes were analyzed in children aged 7 to 11 years. Results children with obesity had increased systolic (p= 0.0017) and diastolic (p= 0.0131) BP and heart rate (p= 0.0022). The children with obesity displayed significantly lower SDNN, RMSSD, NN50, HF (ms), HF (nu), SD1, SD2, and higher LF (ms), LF (nu), LF/HF, SD1/SD2, DFA-α1, and DFA-α2, compared to normal weight. A lower and higher capacity for producing IL-10 (p= 0.039) and IL-2 (p= 0.009), respectively, were found in children with obesity compared to children with normal weight. Although IL-2, IL-4 and IL17A did not correlate with HRV parameters, IL-6 was positively correlated with SDNN, LF (ms) and SD2, TNF-α was positively correlated with LF/HF and SD1/SD2 ratio, and IFN-γ was positively correlated with SDNN, RMMSSD, NN50, LF (ms), HF (ms), SD1, and SD2. Conclusions The findings suggest that children with obesity have impaired autonomic function and systemic low-grade inflammation compared to children within the normal weight range, the inflammatory biomarkers were correlated with HRV parameters in schoolchildren living in the northeastern region of Brazil.

Abstract Objective Children with spina bifida (SB) are at risk for stunting and overweight. However, height and Body Mass Index (BMI) z-score distribution in children and adolescents with SB are unclear. The aim of this study was to examine height and BMI z-score distribution in Brazilian children and adolescents with and without SB. This study further aimed to examine whether height and BMI z-scores differ between individuals with and without SB. Method This study included 101 participants (SB: n= 18; non-SB: n= 83, aged 7-16 years). The World Health Organization (WHO) AnthroPlus software was used to calculate height and BMI z-scores. AnthroPlus z-score distribution graphs were used to examine individual z-scores based on the 2007 WHO normal distribution curve. Effects of the group (SB vs non-SB) on height and BMI z-scores were examined with sequential regression. Results In the WHO distribution graph analysis, height z-scores of participants with SB were slightly left-shifted compared to the WHO normal distribution curve. In the regression analysis, group (SB vs non-SB) was a significant predictor of height z-scores after controlling for sex and age (ΔR2= 0.064, p= 0.010). BMI z-scores of participants with SB were right-shifted compared to the WHO normal curve. However, there was no contribution of the group to BMI z-scores (ΔR2= 0.011, p= 0.301). Conclusions These findings suggest that Brazilian children and adolescents with SB may be at risk for reduced height and increased BMI.

ABSTRACT BACKGROUND: With the increase in the older adult population, it is essential to identify the living and health conditions that can impact the quality of life of these individuals. OBJECTIVES: To identify the domains and factors associated with the quality of life of older adults under the Family Health Strategy program. DESIGN AND SETTING: This was a cross-sectional analytical study was conducted in the municipality of Palmas, Tocantins, Brazil. METHODS: We assessed 449 older adults enrolled in the Family Health Strategy program. Data were collected between April and July, 2018. World Health Organization Quality of Life Assessment (WHOQOL-OLD) was used to assess the quality of life (QoL) and multiple linear regression was used to estimate the factors associated with QoL. RESULTS: The QoL domain with the highest score was death and dying (mean = 70.4), and the lowest score was for sensory functions (mean = 61.0 points). The factors associated with QoL were single marital status (β = -4.55; P = 0.014), level of independence for daily living activities (β = 4.92; P < 0.001), self-assessment of regular health (β = 5.35; P < 0.001), and poor health (β = -8.67; P < 0.001). CONCLUSION: The death and dying domain of QoL presented the highest score. Marital status, impairment in daily activities, and health self-assessment were associated with QoL.

Exploratory Factor Analysis identified a Kaiser-Meyer-Olkin index of 0.901 and Bartlett's Sphericity Test with P < 0.001. We obtained a Cronbach's alpha coefficient of 0.95 and an intraclass correlation coefficient of 0.849. CONCLUSIONS: The Providers Survey, translated and adapted into Portuguese, was named the Work Assessment Instrument for the Recovery of Mental Health. It presented adequate psychometric properties for evaluating work-related practices for the recovery of psychosocial care network users.

ABSTRACT BACKGROUND: Nutritional status and growth curves can affect cognitive development, increase the risk of infection, and contribute to the development of chronic diseases. Its etiology is related to food, socioeconomic, and maternal conditions. However, to date, no data on these parameters exist in the state of Goiás, Brazil. OBJECTIVE: To compare the nutritional status and growth curves of children and adolescents in the city of Goiânia, Goiás, Brazil. DESIGN AND SETTING: This was a cross-sectional study. A total of 529 individuals were recruited from a primary health center in the municipality. METHODS: To assess nutritional status, the sample was divided into three categories: 3–4, 5–10, and 11–19 years, with z-score classification considering body mass index for age. The classification of growth curves was performed considering the median height values for age, assuming two references: (a) young Brazilian population and (b) one recommended for international use. The independent sample T-test was used to compare anthropometric variables. RESULTS: The results showed that the classification of eutrophics represents a predominant percentage between both sexes (men: 03–04 = 55.4%; 05–10 = 57.6%; 11–19 = 53.5 % and women: 03–04 = 53.5%; 05–10 = 63.9%; 11–19 = 56.9%), and growth curves showed differences in specific periods in both sexes. CONCLUSIONS: It can be concluded that children and adolescents from the city of Goiânia present as predominance the eutrophic nutritional status, followed by the risk of overweight, underweight, obesity, and malnutrition of both sexes.

ABSTRACT Managing electrical conductivity levels is one of the fundamentals required to obtain greater production and better quality of vegetables. The aim of this study was to evaluate the effect of electrical conductivity of the nutrient solution on the kohlrabi crop cultivated in semi-hydroponic system. A randomized block design was used with five treatments associated with the electrical conductivity of the nutrient solution (1.31, 1.71, 2.37, 2.98, and 3.75 dS m-1) and four replications. The plants were harvested 78 days after transplanting and evaluated for growth, production, and postharvest quality. Nutrient solution with electrical conductivity (EC) of 1.31 dS m-1 promotes greater production of purple kohlrabi. The increase in EC reduced linearly most of the analyzed variables (leaf area, fresh mass of leaves, bulb and shoot, dry mass of leaves and total, bulb volume and firmness), with more significant losses for the bulb fresh mass (50.54%) and bulb volume (57.37%) variables. The use of nutrient solution with EC between 2.3 and 2.9 dS m-1 increased the vitamin C content and the titratable acidity.

RESUMO O manejo dos níveis de condutividade elétrica é um dos fundamentos necessários para se obter maior produção e melhor qualidade de hortaliças. O objetivo deste trabalho foi avaliar o efeito da condutividade elétrica da solução nutritiva na cultura da couve-rábano cultivada em sistema semi-hidropônico. O delineamento experimental foi em blocos casualizados com cinco tratamentos associados à condutividade elétrica da solução nutritiva (1,31; 1,71; 2,37; 2,98 e 3,75 dS m-1) e quatro repetições. As plantas foram colhidas 78 dias após o transplante e avaliadas quanto ao crescimento, produção e qualidade pós-colheita. Solução nutritiva com condutividade elétrica (CE) de 1,31 dS m-1 proporciona maior produção de couve-rábano roxa. O aumento da CE reduziu linearmente a maioria das variáveis analisadas (área foliar, massa fresca de folhas, bulbos e parte aérea, massa seca de folhas e totais, volume e firmeza de bulbos), com perdas mais expressivas para as variáveis massa fresca de bulbos (50,54%) e volume de bulbos (57,37%). A utilização de solução nutritiva com CE entre 2,3 e 2,9 dS m-1 aumentou o teor de vitamina C e a acidez titulável.

Reuse made by the separation of whey can reduce the waste of human milk. However, the authors are not aware of the literature on treatments in human whey, made available by pasteurization holder, freeze-drying, spray drying, and high hydrostatic pressure. In this context, the present study applied treatments to human whey and evaluated their lipid and immunological quality. Among the results, a different formation in the triacylglycerol profile was evidenced after the application of spray drying and high hydrostatic pressure, while pasteurization and freeze-drying presented ion intensity close to the control human whey. In addition, pasteurization proved to be adequate for lipid nutritional quality and transformation factor-β1 (TGF-β1) concentration, while an increase in interleukin-10 (IL-10) levels was promoted, between 73 and 80%, after freeze-drying, spray drying, and high hydrostatic pressure. Through the principal component analysis, it is noteworthy that the processes presented divergences in terms of the effects caused, with similarity only between pasteurization and freeze-drying in the composition of fatty acids. However, it was observed that all processes were able to maintain the nutrients. Nevertheless, it is relevant to consider individual characteristics presented and the interest in the desired quality, which can be promising as a complementary product to infant feeding.

Carbonyl compounds (CC) can be formed during the craft beer production process, which influence the sensory properties, in addition to their toxicity. The formation of bound CC, in craft beers, is favored by the high reactivity of these substances. This work aimed to quantify 15 carbonyl compounds, in free and bound forms, in craft beers using hydrolysis (bound CC only) and derivatization reactions. Acetaldehyde concentrations ranged from 8.83 to 466.1 µg L-1 (free fraction) and 22.47 to 1665 µg L-1 (bound fraction). Other compounds found were acrolein (free + boundmax.: 2897 µg L-1), benzaldehyde (free + boundmax.: 1326 µg L-1), heptanal (free + boundmax.: 1140 µg L-1) and formaldehyde (free + boundmax.: 97.73 µg L-1). Craft beers showed a proportion of up to 76% for CC in the bound form, which can be related to undesirable flavors in beverages. The consumption of craft beers containing freeand bound-CC (especially acrolein) could pose a risk to the health of frequent consumers.
