Resumen El mejoramiento genético de los cultivares de soja a lo largo de los años se ha centrado en aumentar la capacidad productiva y la tolerancia a algunos factores abióticos y bióticos. Sin embargo, durante la transferencia de genes de interés, algunos genes responsables de una menor tolerancia a los herbicidas pueden integrarse en el genoma del nuevo cultivar. El objetivo de este estudio fue evaluar la selectividad de las asociaciones de herbicidas apli cadas en la post-emergencia de tres cultivares de soja. El diseño experimental utilizado fue un bloque completamente al azar, con cuatro repeticiones. Los cultivares seleccionados fueron M7110 IPRO®, Foco IPRO® y Bônus IPRO®. Los herbicidas y las respectivas dosis (g a.i. ha-1) utilizados fueron: glyphosate (1176), glyphosate + bentazon (1176 + 600), glyphosate + fomesafen (1176 + 175), glyphosate + lactofen (1176 + 120), glyphosate + imazethapyr (1176 + 100), glyphosate + chlorimuron (1176 + 10), glyphosate + cloransulam (1176 + 39,5), y un control sin aplicación de herbicida. Se hizo una nota visual de intoxicación para cada tratamiento. Los componentes de crecimiento y rendimiento evaluados fueron: altura, rodal, peso de cien granos y rendimiento. La aplicación de herbicidas en post-emergencia no alteró la masa vegetal de los cultivares de soja. Además, estos herbicidas no redujeron el rendimiento de los cultivares M7110 IPRO® y Foco IPRO®. Tanto el glifosato aislado como mezclado con lactofen o imazethapyr redujeron el rendimiento del cultivar Bônus IPRO®.

Abstract The genetic improvement of soybean cultivars over the years has focused on increasing the yield potential and tolerance to some abiotic and biotic factors. However, during the transfer of genes of interest, some genes responsible for a lower tolerance to herbicides can be integrated into the genome of the new cultivar. Thus, the objective of this study was to evaluate the selectivity of herbicide associations applied in the postemergence period of three soybean cultivars. The experiment was conducted in a randomized completely block design, with four replications. The selected cultivars were M7110 IPRO®, Foco IPRO®, and Bônus IPRO®. The herbicides and the respective doses (g a.i. ha-1) used were glyphosate (1176), glyphosate + bentazon (1176 + 600), glyphosate + fomesafen (1176 + 175), glyphosate + lactofen (1176 + 120), glyphosate + imazethapyr (1176 + 100), glyphosate + chlorimuron (1176 + 10), glyphosate + cloransulam (1176 + 39.5), and a control without herbicide application. The visual note of intoxication was evaluated for each treatment. The components of growth and yield evaluated were height, stand, weight of one hundred grains, and yield. The application of postherbicide herbicides did not alter the plant stands of soybean cultivars. Additionally, these herbicides did not reduce the yield of the M7110 IPRO® and Foco IPRO® cultivars. Glyphosate isolated and in association with lactofen or imazethapyr reduced the grain yield of the Bônus IPRO® cultivar.

Abstract Objective: To evaluate acute and chronic changes seen on angiographic and histopathological studies of porcine rete mirabile, comparing those treated with the Menox liquid embolic system (LES) and those treated with the Onyx LES. Materials and Methods: Five pigs, each weighing approximately 35 kg, were submitted to rete mirabile embolization under general anesthesia and fluoroscopic guidance, with the Menox LES or Onyx LES. Four animals were treated with the Menox LES and underwent cerebral angiography, followed by euthanasia, at 1, 30, 60, and 90 days after embolization. One animal was treated with the Onyx LES underwent the same procedures at 30 days after embolization. In a subsequent histopathological analysis, we compared the Menox LES and Onyx LES in terms of the acute and chronic changes observed. Results: We observed no significant changes in blood pressure, heart rate, or electrocardiographic parameters that could be attributed to the super-selective infusion of dimethyl sulfoxide or the Menox embolic agent. Fluoroscopy showed adequate material opacity, appropriate progression to the center of the rete mirabile and complete unilateral embolization. Microcatheters were uneventfully detached from the embolized nidus. We observed mild to moderate intravascular and extravascular inflammatory responses, without histological evidence of necrotizing arteritis. There were no adverse neurovascular events. Conclusion: The Menox LES appears to be safe and effective, as well as being apparently equivalent to the Onyx LES in terms of the postprocedure angiographic and histopathological findings.

Resumo Objetivo: Avaliar as alterações angiográficas e histopatológicas agudas e crônicas em rete mirabile suína tratadas com o Menox liquid embolic system (LES) e comparar essas alterações com a embolização com Onyx LES. Materiais e Métodos: A embolização da rete mirabile com Menox LES e Onyx LES foi realizada em cinco suínos pesando cerca de 35 kg sob anestesia geral e orientação fluoroscópica. Quatro animais tratados com Menox LES foram submetidos a angiografia cerebral seguida de eutanásia após 1, 30, 60 e 90 dias e um animal tratado com Onix LES foi submetido ao mesmo procedimento após 30 dias. A análise histopatológica subsequente para alterações agudas e crônicas avaliou o desempenho do Menox LES comparado ao Onyx LES. Resultados: Não foram observadas alterações significativas atribuíveis à infusão superseletiva de dimetilsulfóxido ou Menox nos parâmetros de pressão arterial, frequência cardíaca ou eletrocardiograma. A fluoroscopia mostrou opacidade adequada do material, progressão adequada para o centro da rete mirabile e embolização unilateral completa. Os microcateteres foram retirados do nidus embolizado sem complicações. Observou-se resposta inflamatória intravascular e extravascular leve a moderada, sem indício histológico de arterite necrosante. Nenhum dos casos apresentou eventos neurovasculares adversos. Conclusão: A injeção de Menox LES mostrou-se segura e eficaz, além de ser equivalente ao Onyx LES em relação aos achados angiográficos e histopatológicos pós-procedimento.

ABSTRACT The Caatinga biome in Brazil comprises the largest and most continuous expanse of the seasonally dry tropical forest (SDTF) worldwide; nevertheless, it is among the most threatened and least studied, despite its ecological and biogeographical importance. The spatial distribution of volumetric wood stocks in the Caatinga and the relationship with environmental factors remain unknown. Therefore, this study intends to quantify and analyze the spatial distribution of wood volume as a function of environmental variables in Caatinga vegetation in Bahia State, Brazil. Volumetric estimates were obtained at the plot and fragment level. The multiple linear regression techniques were adopted, using environmental variables in the area as predictors. Spatial modeling was performed using the geostatistical kriging approach with the model residuals. The model developed presented a reasonable fit for the volume m3 ha with r2 of 0.54 and Root Mean Square Error (RMSE) of 10.9 m3 ha–1. The kriging of ordinary residuals suggested low error estimates in unsampled locations and balance in the under and overestimates of the model. The regression kriging approach provided greater detailing of the global wood volume stock map, yielding volume estimates that ranged from 0.01 to 109 m3 ha–1. Elevation, mean annual temperature, and precipitation of the driest month are strong environmental predictors for volume estimation. This information is necessary to development action plans for sustainable management and use of the Caatinga SDTF in Bahia State, Brazil.

ABSTRACT Soil compaction negatively impacts soil physical functions, affecting root growth and crop yield. This study aimed to evaluate different soybean cultivars’ agronomic and physiological performance as a function of compaction in Rhodic Ferralsol under no-tillage (NT) with a clay loam texture in the Brazilian Cerrado biome. The experiment was implemented in Rio Verde, Goias state, central Brazil. The experimental design was a randomized block with a 3x2 factorial scheme with six replications. The first factor corresponded to three soybean cultivars from different maturity groups (MG) identified as super-early (MG = 6.2); early (MG = 6.8), and medium (MG = 7.9). The second factor was the cultivation in compacted and uncompacted soil. The experiment evaluated the soil physical properties: bulk density, total porosity, water content at matric potential -6 kPa, aeration capacity and water and air holding capacity in 0.0-0.1 and 0.1-0.2 m layers, agronomic and physiological traits (gas exchange). Soil compaction negatively affected the agronomic traits of soybean cultivars, with better performance of the medium cycle cultivar. Net photosynthesis, stomatal conductance, and transpiration rates were reduced up to 50% under compaction and were not influenced by cultivars. Our findings suggest that soil compaction negatively affected the performance of soybean cultivars with lower maturity groups reflecting in lower plant height, shoot and root dry mass, number of pods and grain yield. The choice of soybean cultivars with a longer cycle can be an alternative to minimize the adverse effects of soil compaction.

ABSTRACT. The succession of soybean/maize has been largely adopted. Storm damage and crop problems can lead to grain loss, generating maize ear fragments or even whole ears that remain in the soil and still display germination viability, resulting in the occurrence of volunteer plants. In this context, the present study aimed to evaluate the interference of voluntary maize plants on soybean and investigate the susceptibility of maize hybrids to pre-emergence herbicides. In the first step, an experiment was performed evaluating the influence of voluntary maize plant density and spatial distribution on soybean. The experiment was performed in a randomized completely block design (RCBD) with four replications, with treatments disposed in factorial arrangement (2 x 4) + 1. The first factor corresponded to the spatial distribution of maize plants: row or in between soybean rows; while the second factor adopted four infestation densities of maize plants m-2: 4, 8, 12, and 16. The additional treatment consisted of a control without maize plants. For the second step, an experiment was conducted in two locations aiming to determine the efficacy of pre-emergence herbicides in the control of voluntary maize. Both experiments were installed in RCBD in a split-plot scheme with four replications. Fomesafen, lactofen, sulfentrazone, chlorimuron-ethyl, diclosulam, flumetsulam, imazethapyr, clomazone, metribuzin, [sulfentrazone + diuron], [imazethapyr + flumioxazin], and a control without herbicide application were evaluated in the main plot. In each subplot, the maize hybrids DKB310 PRO3™ and DKB390 PRO3™ were evaluated. No influence on the position of voluntary maize on the soybean yield was observed. The presence of the maize population led to a progressive decrease in soybean yield, ranging up to 86%, at 16 plants m-2. DKB390 displayed a stand reduction of 82.88% after the use of diclosulam. Diclosulam led to better results regarding maize plant decreases for both hybrids.

RESUMO Entre as espécies que tem causado maiores prejuízos nos sistemas brasileiros de produção de soja, está o capim-amargoso. Neste contexto, o objetivo deste trabalho foi avaliar o efeito da interferência do capimamargoso na soja cultivada em condições de Cerrado. Para tanto, foram instalados três experimentos à campo, sendo dois simulando área com falhas na dessecação de capim-amargoso na pré-semeadura da soja, com plantas remanescentes desta espécie (E1 e E2) e um no qual simulou a emergência do capim-amargoso ocorreu de forma simultânea a da soja (E3). No E1 e E2, o delineamento utilizado foi o de blocos casualizados (DBC), sendo avaliados cinco tratamentos compostos por densidades crescentes de capim-amargoso (0, 2, 4, 6 e 8 plantas por m2) e quatro repetições. No E3, também foi utilizado o DBC, estando os tratamentos dispostos em arranjo fatorial 2 x 5, com quatro repetições. O primeiro fator foi composto de duas cultivares de soja de ciclo distinto; enquanto que no segundo foram simuladas densidades de capim-amargoso em convivência com a soja, sendo adotadas as mesmas do E1 e E2. O aumento de densidade de capim-amargoso em convivência com a soja proporciona redução na produtividade da cultura, independentemente se estas plantas estavam emergidas na ocasião da semeadura ou se a infestação foi estabelecida após a emergência da soja. A intensidade de redução na produtividade da cultura é maior quando as plantas de capim-amargoso já se encontram entouceiradas na área na ocasião da semeadura da soja, chegando a reduções próximas de 80% na maior densidade de infestação.

ABSTRACT Sourgrass (Digitaria insularis) is one of the main species causing significant losses in Brazilian soybean production systems. Thus, this paper aimed to evaluate sourgrass interference on soybeans grown under Cerrado conditions. Three field experiments were conducted, of which the first two (E1 and E2) simulated sourgrass after pre-sowing burndown, using plants already emerged by the time soybeans were sown; whereas the third (E3) simulated both sourgrass and soybeans emerged simultaneously. Both E1 and E2 were conducted in a randomized complete block design (RCBD) with five treatments based on sourgrass infestation densities (0, 2, 4, 6, and 8 plants m-2) and four replications. In turn, E3 was also carried out in an RCBD but with treatments arranged in a 2 x 5 factorial and four replications. The first factor comprised two soybean cultivars, while the second was sourgrass density levels, just as in E1 and E2. The results showed that increasing sourgrass densities reduced soybean yield regardless of the plant growth stage when the crop was sown. Yield losses were higher when sourgrass plants were already established by the time soybean was sown. Soybean yield losses reached up to 80% under higher sourgrass infestation levels.

Resumo Avaliamos associações da supervisão parental com o comportamento sedentário e a inatividade física em adolescentes brasileiros. Utilizamos dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2015, que avaliou 102.072 escolares do 9° ano. Consideramos sedentários os adolescentes que ficavam ≥3 horas/dia sentados e inativos os que praticaram <60 min/dia de atividade física. A supervisão parental foi avaliada pela frequência (nunca, às vezes, sempre) de atividades com verificar o dever, saber sobre o tempo livre e entender os problemas do adolescente. Foram realizadas análises de regressão logística, ajustadas para variáveis sociodemográficas. Dentre os avaliados, 56,3% eram sedentários e 78,1% inativos. Verificar atividades escolares se associou à menor odds de inatividade e sedentarismo. Ter ciência do que o adolescente fazia no tempo livre e mexer nas coisas do adolescente se associaram a menor odds de inatividade física. A compreensão de problemas pelos responsáveis se associou à menor odds de sedentarismo. Concluímos que maior supervisão parental se associou a menor sedentarismo e menor inatividade física entre adolescentes.

Abstract The scope of this study was to assess the association between parental supervision and sedentary behavior and physical inactivity among Brazilian adolescents. Data of 102,072 students attending 9th grade from public and private school gathered in the 2015 Brazilian National Survey of School Health (PeNSE) were used. Adolescents were sedentary and physical inactive when they spent ≥3 hours/day sitting and practiced less then 60min/day of physical activity, respectively. Frequency of parental supervision (never, sometimes, always) was assessed through checking school homework, knowledge about what the adolescents do in their free time and understanding their problems. Logistic regression was applied and duly adjusted for sociodemographic variables. Among the adolescents, 56.3% were sedentary and 78.1% were inactive. Checking school homework was associated with lower odds of physical inactivity and sedentary behavior. Knowing what adolescents did in their free time and inspecting their belongings was associated with lower odds of physical inactivity. The understanding of problems by parents/guardians was associated with lower odds of sedentary behavior. The conclusion drawn is that greater parental supervision is associated with less physical inactivity and less sedentary behavior.

Abstract INTRODUCTION: Psychosocial aspects need to be discussed in the context of the Covid-19 pandemic. Currently, no studies have investigated the factors associated with social isolation and loneliness among community-dwelling older adults. Therefore, this study analyzed the association of social isolation and loneliness with socioeconomic, clinical, and health characteristics, and Covid-19-related variables, among community-dwelling older adults during the pandemic. METHODS: A cross-sectional study was conducted via a telephone survey of community-dwelling older adults aged ≥60 years in Macapa, Amapa, Brazil. A structured form was used to collect data. Descriptive and inferential analyses were performed using Pearson's correlation test and a linear regression model. RESULTS: Participants comprised 86 community-dwelling older adults with a mean age of 71.78+6.98 years. Among them, 9.3% were diagnosed with Covid-19, of whom 3.5% were hospitalized. Most participants reported no difficulty obtaining food, medicines, or attending routine medical appointments during the pandemic. Furthermore, 23.3% (n=20) were socially isolated, and 20.9% (n=18) reported feelings of loneliness. The mean values for fear, anxiety, and obsession were 19.01±7.25, 1.01±1.90, and 2.84±3.28, respectively. A moderate positive correlation was identified between loneliness and the number of diseases, and a weak positive correlation between loneliness and the number of medications and depressive symptoms and risk for sarcopenia. The linear regression model indicated that higher loneliness scores were associated with a greater number of diseases (β=0.288; p=0.007). CONCLUSIONS: The findings suggest a probable resilience of the older population to Covid-19, despite the association of loneliness with many diseases in times of a pandemic.

RESUMO Com a expansão do plantio de sorgo como cultura de sucessão na segunda safra, os programas de melhoramento precisam ampliar a criação de novas linhagens, visando à produção de híbridos de alto desempenho. O primeiro passo para o processo de seleção consiste na avaliação do desempenho per se das linhagens ou de suas combinações híbridas. O presente trabalho objetivou estimar a capacidade combinatória de linhagens de sorgo granífero em diferentes condições ambientais em plantios na segunda safra. Os ensaios foram conduzidos em sistema de plantio direto, em quatro ambientes: Rio Verde, Sete Lagoas, Teresina e Sinop. Foram avaliados trinta híbridos resultantes dos cruzamentos de seis linhagens restauradoras da fertilidade (R) com cinco linhagens macho-estéreis (A). Foi empregado o delineamento experimental em blocos casualizados, com três repetições. As características avaliadas foram dias para o florescimento, altura das plantas e produtividade de grãos. O ambiente influenciou significativamente nas estimativas de capacidade geral e específica de combinação, e estas sugerem haver importância dos efeitos aditivos e dominantes no controle desses caracteres. As linhagens restauradoras GI.1 e G1.2 contribuíram para aumentar a produtividade de seus híbridos em mais 650 kg.ha-1. Entre as linhagens macho estéreis as melhores para rendimento de grãos foram GII.1 e GII.4 com contribuição acima de 450 kg.ha-1 nos híbridos em que participaram. As combinações híbridas GI.5xGII.3 e GI.1xGII.2 se destacaram por apresentarem potencial de obterem médias altas de produtividade de grãos, associando aspectos favoráveis de dias para o florescimento e altura das plantas.

ABSTRACT The expansion of sorghum as a succession crop, after soybean, has demanded the development of new inbred lines by the breeding programs. The first step in the selection process consists of evaluating the performance per se of the inbred lines or of their hybrid combination. The purpose of this study was to determine the combining ability of sorghum inbred lines under different environment conditions of the crop production areas. The trials were carried out in the second season of 2017, under no-tillage system, in four environments, Rio Verde, Sete Lagoas, Teresina and Sinop. Thirty hybrids, resulting from the crosses of six fertility restoration lines (R) with five male-sterile lines (A) were evaluated. A randomized complete block design with three replicates was used in all experiments. The characteristics evaluated were flowering, plant height and grain yield. The environment significantly influenced the estimates of general and specific combining ability, which suggests that both effects, additive and dominant, are important in the control of these characters. The restoring lines GI.1 and G1.2 contributed to increasing the grain yield of their hybrids by over 650 kg.ha-1. Among the male-sterile lines, the best for grain yield were GII. 1 and GII.4 with contribution above 450 kg.ha-1 in the hybrids in which they participate. The hybrid combinations GI.5xGII.3 and GI.1xGII.2 stood out with potential to obtain high grain yield, associating positive aspects of the other characteristics.

RESUMO O glyphosate é o principal herbicida utilizado no controle de plantas daninhas na cultura da soja Roundup Ready® (RR®), entretanto os diferentes sais e formulações do herbicida disponíveis no mercado podem ocasionar fitointoxicação. Neste cenário, os bioestimulantes surgem como alternativa promissora para mitigar os possíveis efeitos fitotóxicos do glyphosate. Sendo assim, objetivo do trabalho foi avaliar o efeito de doses do bioestimulante MC Extra® associado as formulações de glyphosate nas características agronômicas da cultura da soja tolerante ao herbicida. Conduziram-se dois experimentos nas safras 2015/16 e 2016/17 adotando-se três doses do MC Extra® (0.35; 0.70 e 1.00 kg ha-1) associadas a seis formulações de glyphosate: Glyphotal®, Roundup Original®, Roundup Ready®, Roundup WG®, Roundup Transorb® e Zapp QI®, além de um tratamento adicional sem o uso do herbicida. Em ambos os experimentos foi padronizado o uso da dose de 900 g e. a. ha-1 de glyphosate. Os resultados demonstraram que a maior dose do MC Extra®, em associação às formulações Roundup Original®, Roundup Ready® e Roundup Transorb® e 0.70 kg ha-1 de MC Extra® com Glyphotal® foram as que proporcionaram as maiores produtividades de grãos. Quando usado em conjunto com o herbicida, há a necessidade de aumento da dose do MC Extra® para se ter maiores produtividades de grãos da soja.

ABSTRACT Glyphosate is the main herbicide used in the Roundup Ready® (RR®) soybean crop. However, the different salt and herbicide formulations available on the market can lead to crop intoxication. In this scenario, biostimulants appear as a promising alternative to mitigate the possible phytotoxic effects of glyphosate. Thus, the objective of this work was to evaluate the effects of different MC Extra® biostimulant doses associated with glyphosate formulations on the agronomic characteristics of a herbicide-tolerant soybean cultivar. Two experiments were conducted in the 2015/16 and 2016/17 seasons with three doses of MC Extra® (0.35, 0.70, and 1.00 kg ha-1) associated with six formulations of glyphosate: Glyphotal®, Roundup Original®, Roundup Ready®, Roundup WG®, Roundup Transorb®, and Zapp QI®, plus additional treatment without the use of the herbicide. In both experiments, we used 900 g e.a. ha-1 of glyphosate. The results showed that the highest dose of MC Extra®, in combination with the Roundup Original®, Roundup Ready®, and Roundup Transorb® formulations and 0,70 kg ha-1 of MC Extra® with Glyphotal® provided the highest grain yields. When used in conjunction with the herbicide, there is a need to increase the dose of MC Extra® to obtain higher soybean yields.

The aim of the present study was to systematically review the results of Brazilian studies that examined the motor development of preschool children using the TGMD-2 test, considering the different regions of Brazil, as well as to analyze the results related to the factors associated with the performance in the test TGMD-2; we reviewed the LILACS and SCIELO databases using the term “TGMD-2” as the descriptor, searching for original published studies from 2007 to 2018, with full text available, in the Portuguese and English languages, which evaluated motor performance in preschool children using TGMD-2; data extraction included items: first author, local, periodical, objectives, design, sample characteristics, test performance results and related factors; quality of the studies was also evaluated. The ten studies included in the review indicated differences in motor performance in different regions. Signs of better motor performance were found in children of private school and who practice physical activity guided by a physical education professional.

RESUMO Objetivo: avaliar o conhecimento, atitude e prática de mulheres sobre o exame preventivo do câncer cervico-uterino e investigar sua associação com as variáveis sociodemográficas. Método: estudo transversal, realizado de julho a setembro de 2015, com 500 mulheres cadastradas nas Unidades Básicas de Saúde do Distrito Sanitário V, do município de Recife-PE. Para a coleta de dados utilizou-se um formulário semiestruturado. Na análise estatística, foi aplicado o teste Qui-Quadrado, Teste Exato de Fisher e, na análise multivariada, o modelo de Poisson e estatística de Wald. Resultados: a prevalência de conhecimento, atitude e prática adequados foi de 35,2%, 98% e 70,6%, respectivamente. O conhecimento adequado foi associado a não ter filhos, ter renda familiar de dois salários mínimos e religião espírita/afro-brasileira. Conclusão: as mulheres realizam o exame, julgam-no necessário, mas não têm conhecimento adequado, o que demonstra a necessidade de ações educativas pelos enfermeiros e demais profissionais de saúde.

ABSTRACT Objective: to evaluate the knowledge, attitude and practice of women on the cervical-uterine cancer screening and to investigate their association with sociodemographic variables. Method: a cross-sectional study, carried out from July to September 2015, with 500 women enrolled in the Basic Health Units of the Health District V, of the city of Recife-PE. For data collection, a semi-structured form was used. In statistical analysis, the Chi-square test and Fisher’s Exact Test were applied and, in the multivariate analysis, the Poisson model and Wald statistic. Results: the prevalence of adequate knowledge, attitude and practice was 35.2%, 98% and 70.6%, respectively. Adequate knowledge was associated with having no children, having a family income of two minimum wages and Spiritist/Afro-Brazilian religion. Conclusion: women carry out the examination, deem it necessary, but do not have adequate knowledge, which demonstrates the need for educational actions by nurses and other health professionals.
