Resumo As comunidades quilombolas, estão presentes em diversos estados brasileiros, vivendo em condições de saúde mais precárias. Isto ocorre por conta do isolamento geográfico, das limitações de acesso e da falta de qualidade no serviço quando este é prestado. Nesse sentido, o objetivo do estudo foi analisar a qualidade de vida de mulheres de uma comunidade quilombola do nordeste brasileiro. Estudo observacional, transversal e descritivo. Foram entrevistadas 160 mulheres adultas, através de um formulário para a coleta de perfil e do questionário de Qualidade de Vida WHOQOL – bref. Foi observado que as mulheres tinham em média 40,7 anos (±17,25), casadas, autodeclaradas negras, com fundamental incompleto, do lar, sem renda, com moradia de alvenaria, própria, com até 6 cômodos, abastecidas por caixa de água comunitária, tratada. A Qualidade de Vida, apresentou escores medianos nos domínios: físico (3,18), psicológico (3,4), relações sociais (3,45) e meio ambiente (2,59). Com a realização desta pesquisa foi possível caracterizar a comunidade quilombola de Santa Luzia do Norte-AL quanto as dificuldades de acesso a saúde e geração de renda, fatos que repercutem na sua condição de saúde. Os problemas descritos neste estudo podem contribuir para que ações de saúde sejam planejadas e efetivadas com o intuito de melhorar as condições socioeconômicas e de saúde nessa comunidade, considerando-se o contexto social, político e ambiental, valorizando seus saberes e práticas tradicionais.

Abstract Quilombola communities are present in many Brazilian states living in precarious health conditions. This is due to geographic isolation, limitations to the access of the area in which they live in, and the lack of quality in the service when it is needed to be provided. Therefore, the aim of this study was to analyze the quality of life of women from a quilombola community in northeastern Brazil. It is an observational, cross-sectional and descriptive study. 160 adult women were first interviewed through a form to collect a profile and then it was applied the WHOQOL Quality of Life questionnaire – bref. It was observed that the women were on average 40.7 years old (±17.25), married, self-declared black, who did not finish elementary school, housewife, had no income, with their own masonry house, with up to 6 rooms, supplied by a box of community treated water. Quality of Life had median scores in the domains: physical (3.18), psychological (3.4), social relationships (3.45) and environment (2.59). With this research, it was possible to characterize the quilombola community of Santa Luzia do Norte-AL regarding the difficulties of access to health and income generation, issues that affect their health condition. The problems described in this study can contribute to health actions being planned and carried out in order to improve socioeconomic and health conditions in this community, considering the social, political and environmental context, valuing their traditional knowledge and practices.

Resumo O setor florestal brasileiro se destaca pela tecnologia, práticas de manejo florestal, responsabilidade social e ambiental e, principalmente, alta produtividade, mas pragas exóticas podem reduzir isto. O parasitoide Psyllaephagus bliteus (Riek, 1962) (Hymenoptera: Encyrtidae), percevejos predadores e fungos entomopatogênicos como Beauveria bassiana e Metarhizium anisopliae são inimigos naturais usados no controle biológico do psilídeo-de-concha do eucalipto Glycaspis brimblecombei (Moore, 1964) (Hemiptera: Aphalaridae), praga em plantios de eucalipto. A utilização de fungos entomopatogênicos contra pragas exóticas vem aumentando no setor florestal e a prospecção e identificação de isolados fúngicos é importante para o manejo integrado de pragas. O objetivo deste estudo foi o isolamento e identificação molecular de Cordyceps spp. e avaliar a patogenicidade dos isolados de Cordyceps javanica (LCBPF 11) e Cordyceps fumosorosea (LCBPF 12 e LCBPF 63), obtidos de adultos de Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), ao psilídeo-de-concha G. brimblecombei. Os fungos foram isolados de adultos de B. tabaci encontrados em culturas de soja e tomate e identificados molecularmente. Os conídios foram suspensos em solução com Tween 80 (0,1%) na concentração de 1,0 x 108 conídios/mL e pulverizados sobre dez ninfas de G. brimblecombei por folha de Eucalyptus cortada e colocada sobre gel hidrorretentor no interior de placas de Petri por repetição. O número de insetos mortos foi quantificado, diariamente, por sete dias e transferidos para câmaras úmidas. Cordyceps javanica (LCBPF 11) e C. fumosorosea (LCBPF 12 e LCBPF 63) foram identificados por análise molecular e todos os isolados foram patogênicos para os insetos. Isto indica serem importantes para o manejo de G. brimblecombei e confirma relatos de que, normalmente, fungos causam maiores mortalidades em insetos da mesma ordem daquela da qual foram isolados.

Abstract The Brazilian forestry sector stands out for its technology, forestry management practices, social and environmental responsibility and, mainly, for its high productivity and exotic pests can reduce it. The red gum lerp psyllid Glycaspis brimblecombei (Moore, 1964) (Hemiptera: Aphalaridae) is an important pest in Eucalyptus plantations. The parasitoid Psyllaephagus bliteus (Riek, 1962) (Hymenoptera: Encyrtidae), predatory bugs and entomopathogenic fungi such as Beauveria bassiana and Metarhizium anisopliae are the natural enemies and used in the biological control of the red gum lerp psyllid. The use of entomopathogenic fungi against exotic pests is increasing in the forestry sector and the prospecting and identification of fungus isolates is important for integrated pest management. The objective of this work was the isolation and molecular identification of Cordyceps spp. And to evaluate the pathogenicity of isolates, obtained from Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) adults, against to the red gum lerp psyllid G. brimblecombei. The fungi were isolated from B. tabaci adults found in soybean and tomato crops and molecularly identified. The conidia obtained were suspended in solution with Tween 80 (0.1%) at a concentration of 1.0 × 108 conidia/mL and sprayed on ten G. brimblecombei nymphs per Eucalyptus leaf cut and placed on a hydroretentive gel inside per Petri dishes as a replication. The number of dead insects was quantified, daily, for seven days, and transferred to humid chambers. Cordyceps javanica (LCBPF 11) and C. fumosorosea (LCBPF 12 and LCBPF 63) were identified with a molecular analysis and all isolates were pathogenic to the insects and indicates that they could be used to manage G. brimblecombei and adds to reports that, normally, fungi cause greater mortality on insects of the same order as that from which they were isolated.

Resumo Anticarsia gemmatalis Hünber, 1818 é uma das principais espécies desfolhadoras da cultura da soja. Bacillus thuringiensis Berliner, 1915, é uma bactéria utilizada no controle biológico dessa espécie de praga. Populações resistentes e seus efeitos subletais causados pelo uso da bactéria já foram relatados, no entanto, não há estudos sobre a plasticidade fenotípica na idade adulta exposta a subdoses de bioinseticida à base de Bt. Este trabalho teve como objetivo avaliar a morfometria de adultos de A. gemmatalis em condições de laboratório submetidos ao bioinseticida Dipel® ao longo de três gerações. Os segmentos corporais mensuráveis eram largura, comprimento e área das asas anterior e posterior, o peso do tegumento, tórax, abdômen, asas e todo o adulto de machos e fêmeas. Dentre os tratamentos, CL5 na primeira geração e CL10 na segunda geração foram aqueles com limiares mais baixos em relação ao peso do tórax e abdômen, considerando as proporções do corpo menores que as do sexo feminino. O peso da fêmea na idade adulta foi reduzido em 10% em relação aos machos e, apenas na primeira geração. Os machos têm tamanho corporal maior e plasticidade fenotípica mais pronunciada do que as fêmeas. Este estudo demonstra o primeiro estudo avaliando a plasticidade fenotípica de adultos de A. gemmatalis.

Abstract Anticarsia gemmatalis Hünber, 1818 is one of the main defoliating species in the soybean crop. Bacillus thuringiensis Berliner, 1915, is a bacterium used in the biological control of this pest species. Resistant populations and their sublethal effects caused by the use of the bacteria have already been reported; however, there are no studies on phenotypic plasticity in adulthood exposed to Bt-based bioinsecticide sub-doses. This study aimed to evaluate the morphometry of A. gemmatalis adults under laboratory conditions submitted to the Bt-based bioinsecticide Dipel® over the three generations. The body segments mensuread were width, length, and area of the anterior and posterior wings, the weight of the integument, chest, abdomen, wings, and the whole adult of males and females. Among the treatments, LC5 in the first generation and LC10 in the second generation were those with lower thresholds in relation to the weight of the chest and abdomen, considering the proportions of the body smaller than the females. The female’s weight adulthood was reduced by 10% about males, and, only in the first generation. Males have larger body size and more pronounced phenotypic plasticity than females. Here, we demonstrate the first study assessing the phenotypic plasticity of A. gemmatalis adults.

Resumo O conteúdo de dopamina nas estruturas cerebrais tem sido relacionado à excitabilidade neuronal e várias abordagens têm sido utilizadas para estudar este fenômeno durante o período de vulnerabilidade às crises. No presente trabalho, descrevemos os efeitos da depleção de dopamina após a administração de 6-hidroxidopamina (6-OHDA) na região pars compacta da substância negra de ratos submetidos ao modelo de epilepsia com pilocarpina. A susceptibilidade ao estado de mal epiléptico induzido pela pilocarpina, bem como a frequência de crises espontâneas e recorrentes durante o período crônico do modelo foi determinada. Sendo o hipocampo uma das principais estruturas afetadas no desenvolvimento desse modelo experimental de epilepsia, os níveis de dopamina nessa região foram determinados após a administração da droga. No primeiro experimento, 62% (15/24) dos ratos pré-tratados com 6-OHDA e 45% (11/24) daqueles que receberam ácido ascórbico como solução controle evoluíram para crises límbicas motoras e para o estado de mal epiléptico, após a administração de pilocarpina. A gravidade das crises durante o período agudo do modelo foi significativamente maior nos ratos epilépticos experimentais (56,52%) do que nos ratos controle (4,16%). No segundo experimento, não houve diferença significante entre os grupos quanto à frequência de crises na fase crônica do modelo. Nossos dados mostraram que a dopamina pode desempenhar um papel importante na gravidade das crises na fase aguda da pilo, o que parece ser exercido por sua ação inibitória da dopamina sobre a expressão motora das crises.

Abstract The dopamine content in cerebral structures has been related to neuronal excitability and several approaches have been used to study this phenomenon during seizure vulnerability period. In the present work, we describe the effects of dopamine depletion after the administration of 6-hidroxidopamine (6-OHDA) into the substantia nigra pars compacta of male rats submitted to the pilocarpine model of epilepsy. Susceptibility to pilocarpine-induced status epilepticus (SE), as well as spontaneous and recurrent seizures (SRSs) frequency during the chronic period of the model were determined. Since the hippocampus is one of main structures in the development of this experimental model of epilepsy, the dopamine levels in this region were also determined after drug administration. In the first experiment, 62% (15/24) of 6-OHDA pre-treated rats and 45% (11/24) of those receiving ascorbic acid as control solution progressed to motor limbic seizures evolving to SE, after the administration of pilocarpine. Severeness of seizures during the model´s the acute period, was significantly higher in epileptic experimental rats (56.52%), than in controls (4.16%). In the second experiment, the frequency of seizures in the model’s chronic phase did not significantly change between groups. Our data show that dopamine may play an important role on seizure severity in the pilo’s model acute period, which seems to be due to dopamine inhibitory action on motor expression of seizure.

Resumo Espécies de besouros Scolytinae, em altas populações, podem danificar a madeira e reduzir a produtividade de cultivos florestais. Esses besouros são monitorados com armadilhas iscadas com etanol e o aumento da eficiência das mesmas pode melhorar o manejo integrado desses insetos. O objetivo foi avaliar o aumento da eficiência de captura de Scolytinae com armadilha modelo semifunil, em dois experimentos, um incluindo elementos de madeira e outro aumentando a área de interceptação de voo e correlacionar o número desses besouros coletados com fatores climáticos. No experimento 1, ripas de Eucalyptus urophylla S. T. Blake foram fixadas, diretamente, no frasco coletor e em outro tratamento, além dessas ripas, fitas de Cedrela sp. foram inseridas no interior da mangueira porta isca. No experimento 2, a área de interceptação de insetos na armadilha, originalmente, com 480 cm2, foi ampliada para 1200 cm2 e comparada com a armadilha modelo Pet–Santa Maria com área de interceptação de 550 cm2. Coletas semanais foram realizadas entre maio de 2018 a junho de 2019. Os insetos capturados foram levados ao Laboratório de Biodeterioração da Madeira da Universidade Federal Rural do Rio de Janeiro (UFRRJ) onde foram triados, identificados em nível de família, contados e a abundância correlacionada com fatores climáticos. As análises estatísticas dos dados coletados foram processadas pelo programa BioStat® 5.3. No experimento 1 foram coletados 869 Scolytinae. Os números de besouros coletados por armadilha sem modificação, com ripas de E. urophylla e com ripas de E. urophylla + fita de Cedrela sp. foram semelhantes, 7,3 ± 3,8; 7,8 ± 6,2 e 7,7 ± 5,0 respectivamente. No experimento 2 foram coletados 4398 Scolytinae. O aumento da área de interceptação dos besouros aumentou a eficiência da armadilha semifunil, com 42,7 ± 20,5 Scolytinae coletados por armadilha comparado a semifunil original, 28,6 ± 12,6 e a Pet–Santa Maria, 20,4 ± 10,4. O número de Scolytinae não se correlacionou com os fatores climáticos no experimento 1 e se correlacionou com a temperatura, umidade relativa e velocidade do vento, mas não com a precipitação, no 2. A incorporação de ripas de E. urophylla ou fitas de Cedrela sp. na armadilha semifunil não aumentou o número de besouros coletados, mas, o aumento da área de intercepção de voo e a temperatura, umidade relativa do ar e velocidade do vento se correlacionaram com o número de besouros coletados.

Abstract Scolytinae species that, in high populations, can damage reducing wood production in forest crops. These beetles are monitored with traps baited with ethanol and increasing their efficiency can improve the integrated management of these insects. The objective was to evaluate the increase in the capture efficiency of Scolytinae with a semi-funnel trap model, in two experiments, one including wooden elements and other increasing the flight interception area and to correlate the numbers of these beetles collected with climatic factors. In the experiment 1, Eucalyptus urophylla S. T. Blake slats were directly attached to the collector flask and in another treatment, in addition to these slats, Cedrela sp. strips were inserted inside the bait holding hose. In the experiment 2, the insect interception area in the trap, originally 480 cm2, was expanded to 1,200 cm2 and compared with the model Pet–Santa Maria trap with an interception area of 550 cm2. Weekly collections were carried out between May 2018 and June 2019. The beetles collected were taken to the Wood Biodeterioration Laboratory of the Federal Rural University of Rio de Janeiro (UFRRJ) where they were sorted, identified at family level, counted and their number correlated with climatic factors. Statistical analyzes of the collected data were processed by the BioStat® 5.3 program. In the experiment 1 were collected 869 Scolytinae. The numbers of beetles collected per trap without modification, with E. urophylla slats and E. urophylla slats + Cedrela sp. strips were similar, 7.3 ± 3.8, 7.8 ± 6.2 and 7.7 ± 5.0 respectively. In the experiment 2 were collected 4,398 Scolytinae. Increasing the interception area of the beetles increased the efficiency of the semi-funnel trap, with 42.7 ± 20.5 Scolytinae collected compared to the original semi-funnel trap, 28.6 ± 12.6 and the Pet–Santa Maria, 20.4 ± 10.4, per trap. The number of Scolytinae did not correlate with climatic factors in the experiment 1 and it was correlated with temperature, relative humidity and wind speed, but not with precipitation, in the 2. The incorporation of E. urophylla slats or Cedrela sp. strips in the semi-funnel trap did not increase the number of beetles collected, but, the increase in the flight interception area and the temperature, relative humidity and wind speed were correlated with the number of beetles collected.

Abstract Objectives To compare LISA with INSURE technique for surfactant administration in preterm with gestational age (GA) < 36 weeks with RDS in respect to the incidence of pneumothorax, bronchopulmonary dysplasia (BPD), need for mechanical ventilation (MV), regional cerebral oxygen saturation (rSO2), peri‑intraventricular hemorrhage (PIVH) and mortality. Methods A systematic search in PubMed, Embase, Lilacs, CINAHL, SciELO databases, Brazilian Registry of Randomized Clinical Trials (ReBEC), Clinicaltrials.gov, and Cochrane Central Register of Controlled Trials (CENTRAL) was performed. RCTs evaluating the effects of the LISA technique versus INSURE in preterm infants with gestational age < 36 weeks and that had as outcomes evaluation of the rates of pneumothorax, BPD, need for MV, rSO2, PIVH, and mortality were included in the meta-analysis. Random effects and hazard ratio models were used to combine all study results. Inter-study heterogeneity was assessed using Cochrane Q statistics and Higgin's I2 statistics. Results Sixteen RCTs published between 2012 and 2020 met the inclusion criteria, a total of 1,944 preterms. Eleven studies showed a shorter duration of MV and CPAP in the LISA group than in INSURE group. Two studies evaluated rSO2 and suggested that LISA and INSURE transiently affect brain autoregulation during surfactant administration. INSURE group had a higher risk for MV in the first 72 h of life, pneumothorax, PIVH and mortality in comparison to the LISA group. Conclusion This systematic review and meta-analyses provided evidence for the benefits of the LISA technique in the treatment of RDS, decreasing CPAP time, need for MV, BPD, pneumothorax, PIVH, and mortality when compared to INSURE.

ABSTRACT Objective: To define a reference chart comparing pressure drop vs. flow generated by a set of arterial cannulae currently utilized in cardiopulmonary bypass conditions in pediatric surgery. Methods: Cannulae from two manufacturers were selected considering their design and outer and inner diameters. Cannula performance was evaluated in terms of pressure drop vs. flow during simulated cardiopulmonary bypass conditions. The experimental circuits consisted of a Jostra HL-20 roller pump, a Quadrox-i pediatric oxygenator (Maquet Cardiopulmonary AG, Rastatt, Germany), and a custom pediatric tubing set. The circuit was primed with lactated Ringer’s solution only (first condition) and with human packed red blood cells added (second condition) to achieve a hematocrit of 30%. Cannula sizes 8 to 16 Fr were inserted into the cardiopulmonary bypass circuit with a “Y” connector. The flow was adjusted in 100 ml/min increments within typical flow ranges for each cannula. Pre-cannula and post-cannula pressures were measured to calculate the pressure drop. Results: Utilizing a pressure drop limit of 100 mmHg, our results suggest a recommended flow limit of 500, 900, 1400, 2600, and 3100 mL/min for Braile arterial cannulae sizes 8, 10, 12, 14, and 16 Fr, respectively. For Medtronic DLP arterial cannulae sizes 8, 10, 12, 14, and 16 Fr, the recommended flow limit is 600, 1100, 1700, 2700, and 3300 mL/min, respectively. Conclusion: This study reinforces discrepancies in pressure drop between cannulae of the same diameter supplied by different manufacturers and the importance of independent translational research to evaluate components’ performance.

Resumo A atividade antioxidante do mel de Tetragonisca angustula (TAH) e seu extrato etanólico (TAEE) foram investigados. Os níveis totais de fenólicos (TPC) e flavonóides (TFC) também foram avaliados. Os resultados para TPC foram 19,91 ± 0,38 e 29,37 ± 1,82 mg GAE g-1 e para TFC 0,20 ± 0,02 e 0,14 ± 0,01 mg QE g-1 de TAH e TAEE, respectivamente. As atividades antioxidantes foram 73,29 ± 0,49% e 93,36 ± 0,27% no ensaio DPPH● e 71,73 ± 4,07% e 97,86 ± 0,35% no ABTS●+ para TAH e TAEE, respectivamente. A atividade redutora total foi determinada pelo método de poder redutor (PR) e íon ferrico (Fe III) e os resultados variaram em PR de 151,7 ± 25,7 e 230,7 ± 25,2 mg GAE L-1, para TAH e TAEE respectivamente e para (Fe III) em EC50 0,284 em TAEE e 0,687 em TAH. A análise química por HPLC-DAD do extrato etanólico (TAEE) revelou a presença de ácido ferúlico como componente majoritário no extrato. A análise de RMN 1H confirmou esta estrutura e mostrou a presença de glicose, ácido cítrico, ácido succínico, prolina e derivados de hidrocarbonetos no TAEE. Além disso, a origem botânica também foi investigada e apresentou característica multifloral, tendo encontrado 19 tipos polínicos com predomínio botânico da família Anacardiaceae, sendo o pólen Tapirira predominante (42,6%) e o Schinus secundário (25,7%). Os resultados mostraram que o mel de T. angustula é uma interessante fonte de compostos fenólicos antioxidantes devido à sua origem floral e pode atuar como protetor da saúde humana quando consumido.

Abstract The antioxidant activity of Tetragonisca angustula honey (TAH) and its ethanolic extract (TAEE) were investigated. The total levels of phenolic (TPC) and flavonoids (TFC) were also evaluated. The results for TPC were 19.91 ± 0.38 and 29.37 ± 1.82 mg GAE g-1 and for TFC 0.20 ± 0.02 and 0.14 ± 0.01 mg QE g-1 of TAH and TAEE, respectively. Antioxidant activities were 73.29 ± 0.49% and 93.36 ± 0.27% in the DPPH● assay and 71.73 ± 4.07% and 97.86 ± 0.35% in ABTS●+ for TAH and TAEE, respectively. The total reducing activity was determined by the method of reducing power (PR) and iron ion (Fe III) and the results varied in PR from 151.7 ± 25.7 and 230.7 ± 25.2 mg GAE L-1, for TAH and TAEE respectively and for (Fe III) in EC50 0.284 in TAEE and 0.687 in TAH. Chemical analysis by HPLC-DAD of the ethanolic extract (TAEE) revealed the presence of ferulic acid as majority phenolic component in the extract. The 1H NMR analysis confirmed this structure and showed the also presence of glucose, citric acid, succinic acid, proline and hydrocarbon derivatives. In addition, the botanical origin was also investigated and showed a multifloral characteristic, having found 19 pollen types with a botanical predominance of the Anacardiaceae family, with Tapirira pollen occurring as predominant (42.6%) and Schinus as secondary (25.7%). The results showed that T. angustula honey is an interesting source of antioxidant phenolic compounds due to its floral origin and can act as a protector of human health when consumed.

ABSTRACT Cowpeas are of high socioeconomic importance in the North and Northeast regions of Brazil, whereby the search for alternatives that offer increased productivity with financial returns has become an important challenge. Thus, the objective of this study was to estimate and evaluate the economic indicators of cowpea production in 2015 and 2016 when applying drip irrigation to different depths. Irrigation treatments were based on crop evapotranspiration (ETc). The experiment was laid in a randomized complete blocks design with four treatments (0, 25, 50, and 100% ETc) and six replications. For economic analysis, the results were extrapolated to an area of one hectare. Productivity in 2015 was lower than that in 2016; however, in all treatments, it was always higher when plants were grown under adequate water supply. In both years, the total operating costs were higher under irrigation than under rainfed conditions. The 100% ETc treatment resulted in a greater number of cowpea bags (60 kg) produced and a higher gross revenue than the rainfed treatment by 17 bags ha-1, equivalent to 1,020 kg ha-1 (gross revenue US$ 711.48) and 16 bags ha-1, equivalent to 960 kg ha-1 (gross revenue US$ 867.12), in 2015 and 2016, respectively. Water deficit limited cowpea yield in both years but made cultivation economically unfeasible only in 2015.

RESUMO O feijão-caupi apresenta grande importância socioeconômica nas regiões Norte e Nordeste do Brasil, sendo que a busca por alternativas que ofereçam aumento de produtividade com retorno financeiro tem se tornado um importante desafio. Assim, o objetivo deste trabalho foi estimar e avaliar os indicadores econômicos da produção de feijão-caupi nos anos de 2015 e 2016 quando da aplicação de irrigação por gotejamento em diferentes lâminas. Os tratamentos de irrigação foram baseados na evapotranspiração da cultura (ETc). O experimento foi instalado em blocos ao acaso com quatro tratamentos (0, 25, 50 e 100% da ETc) e seis repetições. Para análise econômica, os resultados foram extrapolados para uma área de um hectare. A produtividade em 2015 foi inferior à de 2016; porém, em todos os tratamentos, a produtividade foi sempre maior quando as plantas foram cultivadas sob irrigação adequada. Em ambos os anos, os custos operacionais totais foram maiores sob irrigação do que sob condições de sequeiro. O tratamento 100% ETc resultou em maior número de sacas de feijão-caupi (60 kg) produzidas e receita bruta superior ao tratamento de sequeiro em 17 sacas ha-1, equivalente a 1.020 kg ha-1 (receita bruta US$ 711,48) e 16 sacas ha-1, equivalente a 960 kg ha-1 (receita bruta US$ 867,12), em 2015 e 2016, respectivamente. A deficiência hídrica limitou a produtividade do feijão-caupi nos dois anos, mas inviabilizou economicamente o cultivo apenas em 2015.

One of the greatest challenges faced by agriculture is the use of agrochemicals and the balance between food production and environmental problems associated with the excessive use of these substances. To overcome this issue, pheromones have been used to trap pests that harm crops. This work reports the use of a layered monocarboxylate, manganese laurate (MnL2), as adsorbing matrix for undecan-2-one (methyl nonyl ketone (MNK)), one of the components of the pheromone of the insect Lobiopa insularis, which is a pest in the strawberry cultivar. The manganese laurate was synthesized by a coprecipitation method and was later characterized using X-ray diffractometry, vibrational spectroscopy, thermogravimetric analysis, and differential scanning calorimetry. The characterization techniques showed that MNK was adsorbed in the manganese laurate structure in a range of 0.08 to 1.13 mg g-1, and this interaction was investigated in a factorial design experiment, in which the variables temperature, time of contact, and matrix:MNK ratio were investigated. A negative effect of increasing temperatures was observed and attributed to substrate volatilization. The adsorption was favored in increasing molar ratios and times of contact, and ideal conditions for the adsorption could be found, indicating that manganese laurate could be applied in controlled-release tests.

Progenesis QI (PQI) is a multiplatform bioinformatics tool that facilitates the identification workflow for metabolomics experiments. PQI uses fragmentation data provided by MassBank of North America (MoNA) libraries, among others, for metabolite annotation. However, PQI does not officially support MoNA libraries and other libraries based on structure-data files (.sdf). This paper describes the development and application of a software named MoNA to Progenesis QI Library Converter, allowing PQI and MoNA by correcting the fragmentation data of the library for Progenesis readability. We evaluated several public experimental datasets, including human plasma, plant extracts, cultured cells, bacteria, rat serum, and rat hippocampus. The results showed that it is mandatory to proceed with file conversion of each library to allow PQI to access fragmentation information from .msp (main spectra profile) files. This step is highly recommended to improve the identification level of the metabolites.

Abstract Objective Few studies have addressed the use of sacral nerve stimulation (SNS) in the treatment of patients with multiple pelvic floor dysfunctions (PFD). So, we evaluated the functional outcomes and level of satisfaction with SNS in selected patients with one or multiples PFD. Methods A prospective database was used to collect information on eligible patients treated for PFD with SNS, and severity of symptoms was assessed with scores and satisfaction rates by visual analogue scale (VAS) at baseline and by the end of follow-up. Results We recruited 70 patients, 98.6% of whom responded positively during the evaluation period (Global Response Assessment ≥ 50% for at least one type of PFD), resulting in the implantation of a permanent SNS device. Additionally, 49 of the patients (71%) had a single PFD (fecal incontinence [FI] = 38; constipation/obstructed defecation syndrome [C/ODS] = 11), while 20 (29%) had more than one PFD (double incontinence/n = 12; double incontinence + C/ODS/n = 8). All scores improved significantly between baseline (pre-SNS) and the end of follow-up (post-SNS), as did VAS in all groups (single and multiple PFD). The pre-SNS scores were higher in patients with a single PFD, including FI (Cleveland clinic Florida incontinence score [CCF-FI]) and C/ODS (Cleveland clinic constipation score [C-CCF] and the Renzi ODS score). The pre-SNS impact of VAS scores was similar in all groups (single and multiple PFD), but the VAS (post-SNS) was significantly lower (better response) for FI alone compared with multiple PFD. Conclusion The SNS technique is an effective and safe option for patients with one or more PFD refractory to conservative measures.

RESUMO Objetivou-se avaliar propriedades físicas de grãos de genótipos de feijão-caupi. O estudo foi conduzido no Laboratório de Armazenamento e Beneficiamento de Grãos e Sementes no Instituto Federal do Norte de Minas Gerais, em Januária, MG. Os tratamentos utilizados foram 17 linhagens-elite e 11 cultivares de grãos de feijão-caupi. O delineamento experimental foi em blocos casualizados, com quatro repetições. As características avaliadas foram a densidade aparente, ângulo de repouso, massa de 1.000 grãos, forma (esfericidade e circularidade), tamanho (área projetada) dos grãos, teor de água e porosidade da massa de grãos. Os genótipos conferem diferentes tamanhos aos grãos de feijão-caupi, o que influencia na variação da densidade aparente, ângulo de repouso e massa de mil grãos. Não houve diferença estatística entre as médias para as variáveis teor de água e porosidade da massa, entre os genótipos avaliados.

ABSTRACT The present study aimed to evaluate the physical properties of cowpea genotypes grains. The study was conducted at the Laboratory for Storage and Processing of Grains and Seeds at the North Federal Institute of Minas Gerais (IFNMG) in Januária, MG, Brazil. The treatments were composed of 17 elite lines and 11 cultivars of cowpea. The experimental design was in randomized blocks with four replicates. The properties evaluated were bulk density, angle of repose, 1000-grain weight, shape (sphericity and circularity), size (projected area) of the grains, water content, and porosity of the grain mass. The genotypes give different sizes to cowpea beans, which influences the variation of bulk density, angle of repose, and 1000-grain weight. There was no statistical difference among the cowpea genotypes evaluated for water content and mass porosity.
