An inert atmosphere is, in some cases, important for the performing of experiments where substances are toxic and/or sensitive to oxygen. However, the high cost and accessibility of an equipment to work under these conditions, results in the fact that most laboratories do not have this kind of equipment. In this paper, we present a simple and efficient project to build a cheap glove box for processes that require an inert atmosphere. The proposed glove box is made using medium density fiberboard (MDF), an acrylic lid, hinges, air valves, PVC gloves and other materials that can be found easily in local stores or on the internet. Tests to verify the quality of the nitrogen atmosphere were performed using the lighter test and niobium pentachloride (NbCl5), which is a moisture/ oxygen sensitive material. The results demonstrated that the equipment is able to maintain an inert atmosphere for several hours, does not permit lighter to function and maintains the NbCl5 stable.

RESUMO O feijão-caupi [Vigna unguiculata (L.) Walp.] é uma importante cultura socioeconomicamente, principalmente na região nordeste e, mais recentemente no centro-oeste do Brasil. Podridão cinzenta do caule causada pelo fungo Macrophomina phaseolina (Tassi) Goid, é importante em regiões semiáridas, onde as condições edafoclimáticas são favoráveis para o desenvolvimento da doença. O objetivo deste estudo foi avaliar a reação de 100 linhagens de feijão-caupi à dois isolados de M. phaseolina. Os experimentos foram conduzidos em delineamento inteiramente casualizado com cinco repetições (duas plantas por parcela). As principais variáveis analisadas foram comprimento da lesão e crescimento relativo a testemunha. Entre os acessos avaliados, 15% das linhagens foram resistentes ao isolado 59 e 11% foram resistentes ao isolado CMM 2106 de M. phaseolina. Portanto, os acessos podem ser utilizados como fontes de resistência a M. phaseolina pelos agricultores diretamente como cultivares ou em futuros cruzamentos de programas de melhoramento genético do feijão-caupi.

ABSTRACT Cowpea [Vigna unguiculata (L.) Walp.] is an important socioeconomic crop in Brazil, mainly in the Northeast and more recently in the Midwest of Brazil. Charcoal rot caused by Macrophomina phaseolina (Tassi) Goid, is an important disease in semiarid regions, where edaphoclimatic conditions are favorable to the development of disease. The aim of this study was to evaluate the response of 100 cowpea lines to two isolates of M. phaseolina. The experiments were conducted in a completely randomized design, with five replications (two plants per pot). The main variables evaluated were lesion length and relative growth compared to control (RGCC). Among the evaluated accessions, 15% of the lines were resistant to isolate 59 and 11% of the lines were resistant to isolate CMM 2106 of M. phaseolina. Therefore, these accessions can be used as a source of resistance to M. phaseolina by farmers directly as new cultivars or in future hybridizations of cowpea genetic breeding programs.

Resumo A necessidade de recorrer ao gestor público de saúde para efetivar o direito ao acesso a medicamentos caracteriza a via administrativa. O estudo analisou as percepções dos usuários que acionaram a via administrativa sobre as barreiras para o acesso a medicamentos no setor público de saúde de uma capital brasileira. Foi realizado estudo de método misto com grupo focal, questionário com demandantes e descrição dos medicamentos demandados pela via administrativa. Os resultados apontam a interdependência da assistência farmacêutica com as áreas de interfaceamento para a garantia do acesso. As barreiras relativas aos indivíduos refletem o comprometimento do desenvolvimento da cidadania, justificando o custo do medicamento motivar a demanda. As barreiras à prestação dos serviços contemplam disponibilidade irregular dos medicamentos, insuficiência de recursos e qualidade insatisfatória dos serviços. A dificuldade para conseguir consultas médicas e a exigência da prescrição originada no setor público são barreiras ao setor saúde. As barreiras acima do setor saúde são cumprimento dos procedimentos administrativos, corrupção e clientelismo. A via administrativa intensifica as iniquidades no acesso à saúde no Brasil.

Abstract The need to request public health managers to ensure the right of access to medicines characterizes an administrative case and the method to do so is called the administrative route. This mixed method study aimed to analyze the perceptions of plaintiffs requesting medications by the administrative route about barriers to access medicines in the Brazilian public health sector. Data were gathered through focus groups and questionnaires. The results point to the interdependence of pharmaceutical services with the interfacing areas to ensure access. The barriers related to individuals reflect the commitment to develop citizenship, justifying the cost of the medicine to motivate the demand. Barriers to service provision include irregular availability of medicines, insufficient resources, and unsatisfactory quality of services. The difficulty in obtaining medical consultations and prescriptions originating in the public sector are barriers to the health sector. The barriers above the health sector are compliance with administrative procedures, corruption, and clientelism. The administrative route intensifies inequities in access to healthcare in Brazil.

Abstract Sulfiting agents are added to crustaceans products to prolong their shelf life. However, depending on the concentration, these agents can be toxic to consumers due to the presence of SO2. In this context, a colorimetric indicator label based on starch and iodine was developed to detect SO2 in shrimp, showing whether the product is safe or not for consumers. The incorporation of iodine into the starch matrix resulted in labels with a smooth and homogeneous surface, and reduced water solubility from 9.26% to around 0.12%. In both in vitro and shrimp paste test, a visual detection response was observed in the label containing 0.02% of iodine when evaluated in the presence of 100 to 160 ppm of SO2, with ΔE* values greater than 5 (can be identifiable by the human eye). Therefore, the elaborated label showed potential as an economical and simple method to detect SO2 concentration in shrimp-based foods.

ABSTRACT Understanding soil organic matter (SOM) dynamics in production systems on tropical soils is necessary to guide strategies to increase SOM formation. This study aimed to evaluate soil carbon (C) dynamics by combining applications of different plant residues used on tropical soils. An incubation study was carried out with and without adding millet (Pennisetum americanum) residues combined with six crop residues (legumes and non-legumes); and one additional treatment with only millet residue. Higher C-CO2 fluxes recorded in jack bean, sunflower and velvet bean residues were correlated with high soluble compound contents (49.5, 49.6 and 32.1 %, respectively). Adding millet residues resulted in positive PE for all residue combinations. Soils without millet, except jack bean, had a negative PE. Residues application promoted four times increase in C-POM content (from 1.04 to 4.2 g kg-1 soil). The C-MAOM content had 2.4 times increase, being more expressive due to its high initial content (from 15.3 to 37.3 g kg-1 soil). The comparison between the final C contents in the SOM fractions showed a significant increase of 8.8 times for MAOM in relation to POM, demonstrating the larger dimension of this C reservoir in the soil. Both combinations of legumes + non-legumes and non-legume + non-legume contributed significantly to the conversion of C to MAOM. The results give insight into possible management strategies for significant C increments in the more stable SOM fractions, depending on the residue type (quality) and residue combination.

ABSTRACT Soil tillage systems can influence crop development. In order to evaluate the effects of tillage equipment on soil physics and soybean development, five soil tillage systems were evaluated (mouldboard plow, disc plow, intermediate harrow, scarifier and rotary hoe) and their effect on aggregates of a dystrophic Red Yellow Latosol. A completely randomized design with four replications was used. The tillage systems influenced the average height of the plants in the soybean crop. Soil preparation with disc plows and moldboards cause larger plant sizes compared to the scarifier. Periodic soil tillage systems do not influence the development and productivity of the soybean crop.

RESUMO Sistemas de preparo do solo podem influenciar o desenvolvimento das culturas. Com o objetivo de avaliar os efeitos de equipamentos de preparo na física do solo e desenvolvimento da soja, foram avaliados cinco sistemas de preparo do solo (arado de aivecas, arado de discos, grade aradora intermediária, escarificador e enxada rotativa) e seu efeito nos agregados de um Latossolo Vermelho Amarelo distrófico. Foi utilizado o delineamento inteiramente casualizado com quatro repetições. Os sistemas de preparo do solo influenciaram na altura média das plantas na cultura da soja. O preparo do solo com os arados de discos e aivecas ocasionam maior tamanho de plantas em comparação ao escarificador. Os sistemas de preparo periódico do solo não influenciam no desenvolvimento e a produtividade da cultura da soja.

Resumo Introdução: A Competência Parental Percecionada (PSE) tem sido associada a comportamentos parentais positivos e, consequentemente, promotores do bem-estar e desenvolvimento harmonioso da criança. A identificação dos seus potenciais determinantes continua a ser um foco de atenção em saúde mental ao avaliar as perceções e cognições parentais ou ao planear intervenções com os mesmos. Materiais/Métodos: Este foi um estudo transversal com uma amostra clínica de uma Unidade de Pedopsiquiatria da Primeira Infância. Todos os pais de crianças avaliadas pela primeira vez foram incluídos e preencheram o questionário de Sentimento de Competência Parental (Parenting Sense of Competence); tradução portuguesa, α=0.75-0.83) e duas perguntas sobre a perceção de apoio recebido pelo outro progenitor e pela família de origem. Foram corretamente preenchidos 34 questionários. A perceção média de competência parental foi comparada entre ambos os pais e foi testada a correlação com as perceções de apoio. A análise estatística foi efetuada no software SPSS® versão 21 através de análise descritiva e correlação de dados (t-test e Pearson r). Resultados: Um total de 34 questionários foram preenchidos. O Sentimento de Competência Parental não diferiu significativamente entre pai e mãe (73.44 vs 72.24, p=0.533). Os pais percecionam-se como mais apoiados, quer pela família de origem (5.09 vs 4.2, p=0.001), quer pelas mães (4.9 vs 4.09, p=0.011). Foi identificada no pai uma correlação positiva entre o Sentimento de Competência Parental e o Sentimento de Apoio pela Família de Origem (Pearson r=0.639, p<0.01). Conclusão: Entre as mães, as perceções de apoio não se correlacionaram com o sentimento de competência parental. Contudo, a correlação encontrada entre os pais enfatiza como a respetiva família de origem poderá influenciar a tríade relacional. As perceções de apoio parental deverão ser exploradas ao considerar as relações horizontais intrafamiliares como um potencial mecanismo de influência das relações verticais, pela sua associação com a competência parental percecionada.

Abstract Introduction: Perceived parental self-efficacy (PSE) has shown an association with positive parental behavior, highlighting its benefit in promoting child well-being and healthy development. The identification of its potential determinants remains a focus of attention in mental health when assessing parental perceptions and cognitions or planning parental interventions. Material/Methods: This was a cross-sectional study in an Early Childhood Child Psychiatry Unit. All parents of babies and toddlers assessed for the first time were included and completed a Parenting Sense of Competence (PSOC) scale (portuguese translation, α= 0.75-0.83) and two additional questions concerning perceptions of support from the other parent and family of origin. Average PSOC was compared between both parents and correlations with perceptions of support were tested. Statistical analysis was conducted in SPSS® version 21 through descriptive analysis and variable correlation (t-test and Pearson r). Results: A total of thirty-four questionnaires were completed. Average PSOC was similar between father and mothers (73.44 vs 72.24, p=0.533). Fathers perceived themselves as more supported than mothers, either from the family of origin (5.09 vs 4.21, p=0.001), as from the other parent (4.91 vs 4.09, p=0.011). A positive correlation was found between father’s PSOC and perception of support from the family of origin (r=0.639, p <0.01). Conclusions: Among mothers of children followed in this Child Psychiatry Unit, support perceptions did not correlate with perceived parental self-efficacy. However, father’s perceived self-efficacy could relate to perceptions of support, raising clinical attention on how fathers and their family of origin can influence the relational triad. Perceptions of parental support should be explored when considering within-family horizontal relations as a potential mechanism influencing vertical relations through its association with perceived self-efficacy.

ABSTRACT Objective: To discuss remote activities in nursing education in the context of the COVID-19 pandemic and amid the global search for strengthening nursing from the perspective of the “Nursing Now” campaign. Method: Theoretical-reflective study based on literature and critical analysis. Discussion: We reflected on the current contextualization of measures to control the COVID-19 pandemic and suspension of face-to-face classes, the adoption of alternative forms of teaching, especially digital online, and the repercussions on nursing teaching strategies. In this case, we faced difficulties in the quality of education, unequal access, and lack of teacher training. Finial considerations: We highlight prejudices in nurses' education by emergency distance learning, in contrast to the world movement for the valorization of sickness. As the inheritance of this process, we must take advantage of technological resources and incorporate them in learning, having as a certainty that the remote model does not contemplate nursing education in its totality. Keywords: Coronavirus. Pandemics. Education, distance. Education, nursing.

ABSTRACT Objective To discuss remote activities in nursing education in the context of the COVID-19 pandemic for strengthening nursing from the perspective of the “Nursing Now” campaign. Method Theoretical-reflective study based on literature and critical analysis. Discussion Reflection about the measures to control the COVID-19 pandemic and suspend in-person classes, the adoption of alternative forms of teaching, especially online ones, and their repercussions on nursing teaching strategies. There were difficulties regarding the quality of education, unequal access, and lack of knowledge from professors. Final considerations The negative impact that emergency distance teaching had on the education of nurses stands out, in contrast to the world movement for the valuing of nurses. The legacy of this crisis must be taken advantage of through the better use of technological resources and their incorporation in teaching, having as a certainty that the distance teaching model does not encompass the totality of nursing education.

ABSTRACT Background: During de-pulping of açai (Euterpe oleracea) for juice production in the Amazonia, large amounts of fibrous waste are daily discarded, a promising substrate for production of high-value cellulose nanofibrils. Therefore, this study sought to evaluate the modifications of açai surface fibers submitted to chemical pretreatment steps and compare the quality of nanostructured films produced with different cycles of mechanical nanofibrillation. Results: A 2-hour pretreatment (at 5% of NaOH) followed by two NaOH/H2O2 bleaching steps resulted in fibers with increased length and reduced diameter compared to raw fibers while preserving fiber integrity and cellulose I structure. The increase of fibers’ grinding cycles from 3 (minimum to gel point) to 21 (maximum suspension thickness) resulted in nanofibril films with higher crystallinity properties, uniform thickness, compacted morphology, and smoother surface. Nanofibril films formed after different numbers of passages exhibited similar mechanical strength, but distinct barrier properties. Conclusion: Açaí waste films produced with fibers submitted to 3 grinding cycles can be recommended for packaging applications that demand easily dissolving, such as instantaneous food. Oppositely, açaí fibers subjected to 21 cycles in grinder provide films suitable for water-resistant packaging, ideal for secondary coatings of papers and paperboards.

ABSTRACT. The objective of this study was to evaluate the performance and digestibility of diets containing different levels of crude propolis for growing rabbits. Forty-eight New Zealand White rabbits, 43 days old, of both genders, were used, distributed in a completely randomized design. There were four diets with different inclusion levels of crude propolis (0.0; 0.5; 1.0 and 1.5%). There was no statistical difference for performance regarding the inclusion levels of crude propolis (p = 0.85), as well as for the variables dry matter consumption, neutral detergent fiber and acid detergent fiber (p ≥ 0.07). Crude protein consumption showed a statistical difference in relation to gender (p = 0.04): males showed higher consumption. However, final weight, total weight gain, daily weight gain and feed efficiency were not influenced by the addition of crude propolis (p ≥ 0.37). Dry matter digestibility, crude protein, neutral detergent fiber and acid detergent fiber were not influenced by the inclusion levels of crude propolis in the diets (p ≥ 0.12). This study indicates that the inclusion of raw propolis up to 1.5% in the diets does not affect the performance parameters of rabbits.

Abstract Background: The association between Diabetes Mellitus (DM) and Infective Endocarditis (IE) is controversial in the literature, since many controversial results have been published. However, when evaluating specifically the evidence on IE and individuals with DM using insulin, we found only two observational studies that considered this variable, with discordant results regarding the prognosis and prevalence of Staphylococcus sp in insulin users compared to non-users. Despite the lack of evidence, in clinical practice the insulin use could be interpreted as minor criteria "injection drug use", using the modified Duke criteria for IE diagnosis. Objectives: To compare the microbiological and valvar profile, as well as the outcome of non-diabetic and diabetic patients with IE who were insulin users or not. Methods: This was an observational, analytical and retrospective study of patients diagnosed with IE between 2003 and 2015 in three tertiary care centers. A total of 211 patients were included, of which 17 were diabetics and 9 were insulin users. Patients were compared using the Shapiro-Wilk normality test and Fisher's exact test, with a significance level of 5%. Results: The mortality from IE in diabetic individuals was higher than that of non-diabetic patients, but with no statistical significance (35.29% vs. 21.1%; p = 0.221), even when the groups were divided into insulin-user diabetic, non-insulin user diabetic and non-diabetic patients (33.3% vs. 37.5% vs. 21.1%, p = 0.229). There was a difference regarding the prevalence of IE caused by S. aureus (57.1% vs. 14.3% vs. 17.4%, p = 0.029) and the involvement of the tricuspid valve (33.3% vs. 0.00% vs. 10.0%, p = 0.034) among insulin users. Conclusion: In our sample, insulin use or the presence of DM did not mean higher in-hospital mortality from IE. It is not possible to generalize the microbiological and valvar findings due to the lack of studies evaluating insulin users in IE; however, particularities have been previously reported and may indicate a different behavior of IE in these patients. New studies considering the insulin use variable are required to elucidate the association between DM and IE.

A bananeira, uma das frutíferas tropicais mais cultivadas, é uma espécie suscetível ao déficit hídrico e apresenta considerável resposta fisiológica à escassez de água. Dessa forma, este estudo objetivou avaliar o comprometimento ecofisiológio de mudas de duas cultivares de banana sob diferentes níveis de estresse hídrico. O experimento foi conduzido na Universidade Estadual do Maranhão, em delineamento inteiramente casualizado, em esquema fatorial 2 x 3 com quatro repetições. Os tratamentos consistiram de duas cultivares de bananeira: Pacovan Ken e Fhia 18 e três regimes hídricos (0%, 67% e 100% CC), totalizando seis tratamentos. A cultivar Pacovan Ken mostrou ser melhor adaptada às condições do estresse hídrico aplicado, com danos mais tardios à integridade do aparato fotossintético das plantas, o que pode estar relacionado ao fato dessa cultivar apresentar maior capacidade de refrigeração do dossel.

Banana is one of the most cultivated fruits in tropical countries, however, the banana tree is susceptible to water deficit, with considerable physiological responses. Thus, the objective of this work was to evaluate ecophysiological parameters of seedlings of two banana cultivars grown in different water stress levels. The experiment was conducted at the State University of Maranhão in a completely randomized design with four replications, using a 2×3 factorial arrangement consisting of two banana cultivars (Pacovan-Ken, and Fhia-18) and three water regimes (0%, 67%, and 100% of the field capacity). The cultivar Pacovan-Ken showed better adaptation to the water stress conditions, and presented less damages to the photosynthetic apparatus of the plants, which may be related to the higher canopy cooling capacity of plants of this cultivar.
