We report a facile hydrothermal method for the synthesis of niobium pentoxide (Nb2O5) under two different temperatures, 120 °C (Nb2O5-120) and 150 °C (Nb2O5-150). The obtained materials were characterized by structural, optical and morphological techniques. Also, the photocatalytic properties of the Nb2O5 samples were evaluated in two reactions under ultraviolet (UVC) irradiation: degradation of methylene blue (MB) and indigo carmine (IC) dyes; and esterification of free fatty acids (FFA) present in waste cooking oil (WCO). The Nb2O5 was formed at different temperatures of synthesis, and the increase in temperature did not cause significant changes in the structural and optical characteristics, but resulted in an increased surface area of the synthesized materials. Both synthesized materials showed excellent efficiency for dye photodegradation. The sample Nb2O5-150 presented the best performance for the MB photodegradation, with almost 85% of the removal efficiency. In this case, the adsorption of MB molecules on the surface of the material was high due to the favorable electrostatic interaction and also because of its high surface area. For the IC photodegradation, the adsorption was insignificant, and both samples presented approximately 100% of the removal efficiency. These materials were also promising for the reduction of free fat acids in waste oil by photoesterification. NbO Nb O (Nb2O5 12 C Nb2O5120 (Nb2O5-120 15 Nb2O5150. Nb2O5150 .

Abstract This article aims to examine the effects of weekend admission on in-hospital mortality for patients with acute myocardial infarction (AMI) in Brazil. Information from the Hospital Information System of the Unified Health System (SIH/SUS) of urgently admitted patients diagnosed with acute myocardial infarction (AMI) between 2008 and 2018 was used, made available through the Hospital Admission Authorization (AIH). Multivariable logistic regression models, controlling for observable patient characteristics, hospital characteristics and year and hospital-fixed effects, were used. The results were consistent with the existence of the weekend effect. For the model adjusted with the inclusion of all controls, the chance of death observed for individuals hospitalized on the weekend is 14% higher. Our results indicated that there is probably an important variation in the quality of hospital care depending on the day the patient is hospitalized. Weekend admissions were associated with in-hospital AMI mortality in Brazil. Future research should analyze the possible channels behind the weekend effect to support public policies that can effectively make healthcare equitable. inhospital (AMI Brazil SIH/SUS SIHSUS SIH SUS (SIH/SUS 200 201 used AIH.

Abstract Introduction: Chronic kidney disease is usually asymptomatic, and its diagnosis depends on laboratory tests, with emphasis on serum creatinine and proteinuria. Objective: To assess knowledge on the role of serum creatinine as a biomarker of kidney function in a sample of the Brazilian population. Method: Cross-sectional observational study conducted in São Paulo (SP, Brazil), in which a random adult population was interviewed. Results: A total of 1138 subjects were interviewed, with a median age of 36 years old (27–52); 55.1% were female. Regarding the “creatinine” biomarker, 40.6% stated they had never performed such a test. When asked about their knowledge on the usefulness of this exam, only 19.6% knew its function. The other responses were “I don’t know” (71.6%), evaluating heart function (0.9%) and liver function (7.8%). Of those who reported they had already taken a creatinine test, only 29.4% correctly identified the role of creatinine. When dividing the groups into “knows” and “does not know” the function of creatinine, a statistically significant difference (p < 0.05) was observed regarding level of education, female sex, being a healthcare student/worker, having ever measured creatinine, knowing someone with kidney disease and older age. In the multivariate analysis, the main variable related to knowing the creatinine role was having previously taken the test (OR 5.16; 95% CI 3.16–8.43, p < 0.001). Conclusion: There is a significant lack of knowledge about creatinine and its use in checkups. The results indicate that greater efforts are needed from healthcare professionals to raise awareness on the role of serum creatinine.

Resumen La aplicación de herbicidas preemergentes es una estrategia de control de malezas, sin embargo, estos productos deben presentar residualidad para el control de diferentes flujos germinativos. Este estudio tuvo como objetivo evaluar la eficacia de herbicidas preemergentes en diferentes flujos de germinación de Merremia aegyptia, Mucuna aterrima y Ricinus communis, cuando se aplican sobre diferentes cantidades de paja y diferentes períodos secos simulados. El experimento se realizó en un diseño factorial 4 × 2 × 2 con cuatro repeticiones, el tratamiento incluye cuatro períodos secos (0, 30, 60 y 90), dos cantidades de paja (0 y 10 t ha-1) y dos flujos de germinación. Los herbicidas amicarbazona (1225 g ha-1); imazapic (147 g ha-1), sulfentrazona (800 g ha-1) y tebuthiuron (900 g ha-1), se aplicaron para el control de malezas antes de la emergencia, y los flujos de flujo de germinación se evaluaron a los 7, 14, 21, 28 y 35 días después de la emergencia de especies (DAE), mientras se verifica la masa seca. La amicarbazona presentó una reducción del control para todas las especies en los periodos secos más prolongados y presencia de paja. La amicarbazona mostró menos del 80% de control para todas las especies a los 90 días del período seco en presencia de paja. Imazapic no presentó residuo control para ninguna de las especies analizadas. Para sulfentrazona, la cantidad de paja no afectó el control de las malezas en diferentes flujos de germinación, mostrando el mismo patrón de control independientemente de la cantidad de paja, porcentajes de control superiores al 80% independientemente de la cantidad de paja. Los herbicidas asociados a cantidades de paja y periodos secos tienen impacto sobre las especies de malezas M.aegyptia, M.aterrima y R. communis.

Abstract Preemergent herbicides are a frequent weed control strategy. Considering different crop germinative fluxes, these products must present long-lasting weed control. This study evaluated preemergent herbicides in different germination fluxes of Merremia aegyptia, Mucuna aterrima and Ricinus communis when applied to different quantities of straw and different simulated dry periods. The experiment was conducted in a 4 × 2 × 2 factorial design with four replications. The treatments included four dry periods (0, 30, 60, and 90 days), two straw quantities (0 and 10 t ha-1), and two germination fluxes. The herbicides amicarbazone (1225 g ha-1), imazapic (147 g ha-1), sulfentrazone (800 g ha-1), and tebuthiuron (900 g ha-1) were applied for preemergence weed control, and germination flush fluxes were evaluated at 7, 14, 21, 28, and 35 days after emergence (DAE) while verifying plant dry mass. Amicarbazone controlled less than 80% of the studied species at the 90-day dry period in the presence of straw. Imazapic did not present control residue for any of the species analyzed. Sulfentrazone showed the same control pattern at all germination fluxes, regardless of the amount of straw. Tebuthiuron successfully controlled all species in the first germination flush, exceeding 80% regardless of the amount of straw. Herbicides associated with straw quantities and dry periods have a significant impact on M. aegyptiaca, M. aterrima and R. communis.

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 BACKGROUND: Considering the ability of the health and self-management in diabetes questionnaire (HASMID-10) to verify the impact of self-management on diabetes, we highlight its relevance to scientific research and clinical applicability. However, to date, no study has been conducted to scientifically support its use in other languages. OBJECTIVE: To translate, cross-culturally adapt, and validate the HASMID-10 into the Brazilian Portuguese. DESIGN AND SETTING: A translation, cross-cultural adaptation, and validation study conducted at Ceuma University. METHODS: Study was conducted in accordance with the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and Consensus-based Standards for the Selection of Health Measurement Instruments. We included participants of both sexes diagnosed with diabetes, aged between 18 and 64 years, and without cognitive deficits or any other limitations that would prevent them from answering the questionnaire. We assessed participants using the problem areas in diabetes (PAID) scale and HASMID-10. We assessed reliability using a test-retest model with a 7-day interval between assessments. We used intraclass correlation coefficient (ICC), 95% confidence interval (CI), standard error of measurement (SEM), minimum detectable difference (MDD), Spearman correlation coefficient, and floor and ceiling effects. RESULTS: Sample comprised 116 participants, most of whom were women, overweight, non-practitioners of physical activity, and nonsmokers. We observed significant correlations (P = 0.006; rho = −0.256) between the HASMID-10 and PAID, adequate reliability (ICC = 0.780) and internal consistency (Cronbach's alpha = 0.796). No ceiling or floor effects were observed. CONCLUSION: HASMID-10 has adequate measurement properties and may be used for Brazilians.

ABSTRACT The coffee sector is estimated to have a retail market value in excess of USD 83 billion, and over 125 million jobs have been created in the global coffee chain. The coffee specialty market has recently increased significantly, generating opportunities to certify coffee beans produced by sustainable practices. This avoids practices potentially harmful to the environment. Agroforestry, organic farming, intercropping, and soil conservation strategies are examples of sustainable alternatives in the production of coffee. In this review, we focus on practices for the sustainable management of coffee plantations that can help farmers fight problems caused by global warming. More specifically, we address soil organic matter and microbiota, the use of Urochloa grass as intercrop in coffee plantations, shading systems (including agroforestry), and organic coffee production. We concluded that from the agronomic viewpoint, we already have production techniques that can replace traditional ones with significant advantages accruing to the quality of coffee orchard ecosystems. Nevertheless, we need scientific research efforts to deal with the existing gaps and the engagement of the whole coffee chain as a means of guaranteeing an adequate profit to those smallholders who adopt and maintain sustainable practice and are capable of bringing several positive changes to the coffee crop, including the use of microbia-based commercial products and new organic sources of nutrients to complement chemical fertilizers and improve coffee quality. 8 billion 12 significantly environment Agroforestry farming intercropping review warming specifically microbiota agroforestry, agroforestry , agroforestry) viewpoint ecosystems Nevertheless crop microbiabased microbia based 1

ABSTRACT Several studies have assessed the applicability of the Myofascial Self-Release Technique (MSRT) in the acute improvement of flexibility in various sports and/or different populations. However, its integration into school physical education classes becomes challenging due to the high cost of materials. Therefore, the aim was to investigate the effect of MSRT on schoolchildren using both original foam rollers and rollers made from low-cost adapted materials. Thirty schoolchildren participated in the study and were randomly grouped into: Control Group (CG), Original Roller Group (ORG), and Adapted Roller Group (ARG). Flexibility was evaluated before and after the application of MSRT. MSRT was performed on target muscles once for 30 seconds with intervals of 15 seconds between stimuli. Comparisons in pre- and post-MSRT flexibility were assessed using the Student's t-test, with a significance level adopted of p <0.05. It was found that MSRT in ORG and ARG significantly increased schoolchildren's flexibility by 7.53% and 16.5%, respectively. Therefore, the use of rollers made with alternative (adapted) material for applying MSRT appears to be a more financially accessible way to be used in physical education classes and opens possibilities for its application beyond schools.

RESUMO Diversas pesquisas têm avaliado a aplicabilidade da técnica de auto liberação miofascial (ALM) na melhora aguda da flexibilidade em inúmeros esportes e/ou populações diferentes. No entanto, torna-se difícil sua inserção nas aulas de educação física escolar pelo elevado custo dos materiais. Dessa forma, buscou-se investigar o efeito da ALM em escolares por meio da utilização de rolos de espumas originais e com rolos confeccionados com materiais adaptados de baixo custo. Participaram da pesquisa 30 escolares, que foram aleatoriamente agrupados em: Grupo Controle (GCT), Grupo Rolo Original (GRO) e Grupo Rolo Adaptado (GRA). A flexibilidade foi avaliada antes e após a aplicação da ALM. A ALM foi realizada em músculos alvos uma vez por 30 segundos com intervalos de 15 segundos entre os estímulos. As comparações na flexibilidade pré e pós ALM foram avaliadas utilizando o teste de t student, com nível de significância adotado de p<0,05. Verificou-se que a ALM no GRO e GRA aumentaram agudamente a flexibilidade dos escolares em 7,53 e 16,5%, respectivamente. Assim, a utilização de rolos confeccionados com material alternativo (adaptado) para aplicação da ALM se mostra uma forma mais acessível financeiramente para ser utilizada nas aulas de educação física e abre possibilidades para sua aplicação para além das escolas.

Abstract The objective of this work was to evaluate the effect of the dietary addition of calcium anacardate as a source of phenolic compounds on the reproductive performance and blood antioxidant parameters of New Zealand White female rabbits. Twenty-seven New Zealand White female rabbits were distributed in a randomized complete block design with three treatments and nine replicates, considering one animal as the experimental unit. The treatments consisted of pelleted diets with different inclusion levels of calcium anacardate (0, 0.5, and 1.0%). The inclusion of calcium anacardate in the diets increased the concentration of phenolic compounds and the antioxidant capacity in the blood of lactating female rabbits. Calcium anacardate at the level of 1.0% improves the feed conversion ratio during gestation and increases the phenolic compounds and antioxidant capacity in the blood serum of female rabbits at 21 days of lactation.

ABSTRACT Introduction: measuring the severity of traumatic injuries is crucial for predicting clinical outcomes. Whereas the Injury Severity Score (ISS) has limitations in assigning scores to injuries at the same site, the New Injury Severity Score (NISS) corrects for this problem by taking into account the three most severe injuries regardless of the region of the body. This study seeks to comprehend the clinical and epidemiological profile of trauma patients while comparing the effectiveness of scales for predicting mortality. Methods: a descriptive, observational and retrospective study using records of patients who underwent thoracotomy at the Hospital das Clínicas of the Federal University of Triângulo Mineiro between 2000 and 2019. Demographic data, mechanisms of injury, affected organs, length of stay and mortality were analyzed. Injury severity was assessed using the ISS and NISS, and statistical analyses were conducted using MedCalc and SigmaPlot. Results: 101 patients were assessed, on average 29.6 years old, 86.13% of whom were men. The average duration of hospitalization was 10.9 days and the mortality rate was 28.7%. The ROC curve analysis revealed a sensitivity of 68.97%, specificity of 80.56% and area under the curve of 0.837 for the ISS, and 58.62%, 94.44% and 0.855 for the NISS, respectively.

RESUMO Introdução: a medição da gravidade das lesões traumáticas é essencial para prever os desfechos clínicos. Enquanto o Injury Severity Score (ISS) tem limitações ao atribuir pontuações às lesões no mesmo local, o New Injury Severity Score (NISS) corrige esse problema ao considerar as três lesões mais graves independentemente da região corporal. Este estudo visa entender o perfil clínico-epidemiológico dos pacientes traumatizados, comparando a eficácia das escalas para prever mortalidade. Métodos: estudo descritivo, observacional e retrospectivo utilizando registros de pacientes submetidos à toracotomia no Hospital das Clínicas da Universidade Federal do Triângulo Mineiro entre 2000 e 2019. Dados demográficos, mecanismos de lesão, órgãos afetados, tempo de internação e mortalidade foram analisados. A gravidade das lesões foi avaliada usando o ISS e NISS, e as análises estatísticas foram conduzidas no MedCalc e SigmaPlot. Resultados: Foram avaliados 101 pacientes, em média com 29,6 anos, sendo 86,13% homens. A média da internação foi de 10,9 dias e a taxa de mortalidade foi de 28,7%. A análise da curva ROC revelou uma sensibilidade de 68,97%, especificidade de 80,56% e área sob a curva de 0,837 para o ISS, e 58,62%, 94,44% e 0,855 para o NISS, respectivamente. O índice de Youden indicou 0,49 para o ISS e 0,53 para o NISS. Conclusão: o estudo demonstrou semelhante eficácia entre o NISS e o ISS na previsão de mortalidade. Esses resultados geram implicações importantes na aplicação dessas escalas no ambiente hospitalar. É essencial que os profissionais conheçam tais escalas para aplica-las adequadamente no contexto de cada paciente.

Abstract This article presents the incorporation of information and communication technologies on the teaching-learning process of geotechnical engineering to improve the quality of education and provide practical knowledge to civil engineering students. The content of this paper is divided into three main modules, which are: Treatment of laboratory tests results, Slope stability and Rock mass stability. For this, some software were used, including 2D limit equilibrium stability analysis, stability analysis of rock wedges and a dynamic mathematics, to obtain and analyze soil shear strength parameters, among others. Furthermore, a digital tool was developed to analyze the results gathered in compaction, one-dimensional consolidation, and direct soil shear tests, in order to clarify the relationship between theoretical concepts and practical results of the tests and analyses and to help students on doubts, in addition to increase their interest and motivation to perform the complete interpretation of the collected data. The activities were conducted in classes of geotechnical disciplines of the undergraduate course in Civil Engineering at the Federal University of Viçosa, aiming to promote active learning and improve teaching quality. Based on the results of an applied feedback questionnaire, it was observed that most students were satisfied with the resources used in the classroom, demonstrating that the implemented digital tools work as a didactic instrument that facilitates learning and comprehension of practical problems, in addition to enabling the resolution of several geotechnical engineering problems much more quickly and efficiently. teachinglearning modules are D mathematics parameters others Furthermore compaction onedimensional one dimensional consolidation doubts data Viçosa questionnaire classroom efficiently

Silver(I) complexes of amantadine (atdH), memantine (mtnH) and rimantadine (rtdH), named Ag-atd, Ag-mtn and Ag-rtd, respectively, were recently synthesized and described in the literature as promising antibacterial agents. In the present study, the cytotoxicity of such complexes was evaluated against cultures of primary epidermal keratinocytes (HaCaT) and murine melanoma tumor cells (B16-F10), and mutagenicity was studied by the Ames test to investigate their abilities to induce gene mutations. The Ames test was performed using Salmonella Typhimurium strains (TA98, TA100, TA102 and TA97a) capable of detecting frameshift and base pair substitution gene mutations, in experiments with and without metabolic activation (microsomal fraction S9). This study revealed significant cytotoxic activity against tumor cells and selectivity of Ag-atd and Ag-rtd complexes when compared to non-tumor human keratinocyte cells. Moreover, the Ag(I) complexes did not induce a significant growth in the number of revertant colonies when comparing with the negative control, both in the experiments without and with metabolic activation, indicating absence of mutagenic activity. The results are encouraging and collaborate in the genotoxicological investigations necessary for understanding the interaction and ability of the silver complexes to induce mutations and contribute to ensure their uses as future antibacterial or antitumor agents.

Abstract The use of growth regulators (GRs) in a mechanized bench grafting system is essential for the final quality of grafted grapevine plants. In Brazil, the GRs used (commercial waxes) are imported, increasing the production cost for nurseries. This work aimed to test the in vitro callus co-cultivation technique as a strategy for prospecting effective doses and mixtures of GRs for in vivo graft union on grapevines. Two genotypes were used as scions (‘Bordo’ and ‘Riesling Italico’) and two as rootstocks (‘SO4’ and ‘P1103’). Callus from different scion/rootstock combinations were co-cultivated, varying the doses (0.25 to 20 mg l-1) of auxins (DBA, IAA and IBA) and cytokinin (BAP), following the Doehlert design. The best in vitro treatments were validated in vivo, in plants grafted with an ‘omega’ cutter machine. Multivariate and non-parametric methods were applied to integrate the results. In vitro prospecting combined with the in vivo validation strategy allowed us to select effectively the IAA(2.50 mg l-1) plus BAP(1.00 mg l-1) formulation with the potential to induce graft callus union similar to commercial waxes. The induction intensity varied among the genetic combinations but was similar in the in vitro and in vivo conditions.

Resumo A utilização de reguladores de crescimento (RC) no sistema de enxertia de mesa da videira são fundamentais para a qualidade final das mudas. No Brasil, os RC utilizados (ceras comerciais) são importados, aumentando o custo de produção para os viveiristas. Este trabalho teve como objetivo testar a técnica do cocultivo de calos in vitro na prospecção de doses e misturas de RC para indução da enxertia in vivo da videira. Foram utilizados dois genótipos como copas (‘Bordo’ e ‘Riesling Italico’) e dois como porta-enxertos (‘SO4’ e ‘P1103’). Calos das combinações copa/porta-enxerto foram cocultivados, variando-se as doses (0,25 a 20mg l-1) de auxinas (DBA, IAA e IBA) e citocinina (BAP), seguindo o delineamento Doehlert. Os melhores tratamentosin vitro foram validados in vivo, em plantas enxertadas com máquina deenxertia tipo ‘omega’. Métodos multivariados e não paramétricos foram aplicados naintegração dos resultados. A prospecção in vitro combinada com a validação in vivo foi eficaz na seleção da formulação IAA (2,50mg l-1) mais BAP (1,00mg l-1) com potencial parainduzir o calo da enxertia de forma semelhante à cera comercial. A intensidade dessa indução variou entre as combinações genéticas de forma similar tanto na condição in vitro como na in vivo.

Biocomposites have gained attention in the packaging industry due to their potential as sustainable alternatives to conventional synthetic materials. In this study, novel cotton incorporated poly(lactic acid)/thermoplastic starch biocomposites were developed for packaging applications using in short shelf life products the extrusion method. Pelletized samples obtained by extrusion were stamped from plates obtained by compression and were characterized through measurement of density, hardness, contact angle and water absorption, as well as Fourier transform infrared spectroscopy (FTIR), thermal analysis and scanning electron microscopy (SEM). No significant changes in the density results were observed. A slight increase in the hardness of formulations in relation to the PLA was associated with the presence of cotton fiber in biocomposites. The FTIR results revealed physical interaction of PLA, TPS and cotton fiber. By DSC analysis, for all formulations the melting exhibited only one peak, suggesting good homogeneity and interaction among the components, as observed by TG/DTG results, and corroborating SEM analysis. The biocomposite PLA/TPS/Cotton 85/10/5 wt.% displayed greater increase in water absorption than both 95/5/0 and 90/5/5 wt.% formulations, which can be attributed to the increase in starch proportion, confirming the contact angle results. The hydrophilic tendency corroborated the biodegradation process in the packaging end-of-life. materials study polylactic poly lactic acid/thermoplastic acidthermoplastic acid /thermoplastic thermoplastic method FTIR, , (FTIR) SEM. .
