Abstract Neuromuscular electrical stimulation (NMES) can be an alternative to conventional exercising. This randomized clinical trial evaluated the effect of NMES in type 2 diabetes patients. Twenty-eight individuals with type 2 diabetes were assigned to NMES (n=14) or NMES-placebo (n=14) applied to knee extensor muscles for 60 minutes. Glucose variability, microvascular function and endothelial function were evaluated through continuous glucose monitoring system, near infrared spectroscopy and flow-mediated dilatation, respectively. Glucose levels (mg/dl) decreased 2h (184 ± 11 vs 223 ±15), 3h (179 ± 12 vs 219 ±14) and 4h (177 ± 12 vs 212 ±12) after NMES, in comparison to NMES-placebo. No differences in glucose variability were found: coefficient of variation (%) at 0-6h (11.4±1.3 vs 11.4±1.2), 6-12h (9.8±1.0 vs 11.6±1.6), 12-18h (15.5±2.0 vs 11.4±2.1), 18-24h (12.8±2.3 vs 10.0±1.6); standard deviation (mg/dl) at 0-6h (21.6±2 vs 24.6±3.5), 6-12h (19.5±1.8 vs 20.3±2.8), 12-18h (29.9±3.5 vs 21.3±2.8),18-24h (22.8±4.1 vs 16.6±2.0) and mean amplitude of glycemic excursions (mg/dl) 54.9±25.0 vs 70.3±35.7. Endothelial and microvascular functions did not change. In conclusion, one acute NMES session was strong enough to trigger glucose reduction in individuals with type 2 DM, but it failed to induce any significant change in glucose variability, endothelial and microvascular functions.

Abstract At high temperatures, concrete may exhibit adverse mechanical behavior that compromises the safety of structures. Thus, it is necessary to study and develop concrete that can obtain greater performance in situations of exposure to high temperatures. In this regard, the present study investigates the replacement of 25% of sand by expanded vermiculite in different types of concrete and its performance when subjected to room temperature and punctual temperatures, of little content in literature, such as 200°C, 400°C and 800°C. This study also innovates by proposing the evaluation of prototypes exposed to high temperatures exclusively according to the perspectives of Brazilian technical standards, without resorting to international guidelines. Thus, the consistencies of the mixtures were determined and analyzed, as well as physical and mechanical tests that were carried out with the produced concrete. Among the results found are: vermiculite reduces the workability of the concrete mixture; vermiculite is not recommended for high-performance concrete, as it can significantly reduce its mechanical properties; in general terms, concrete that has a design strength of 50 MPa benefits from replacing the fines aggregate with vermiculite. From 400°C of exposure, all of the concrete samples showed cracks. The spalling phenomenon was also noticed in some specimens. The developed concrete samples cannot be characterized as lightweight concrete according to Brazilian standards, but o can be recommended as structural concrete given that their apparent specific mass is greater than 2000 kg/m3. structures Thus regard 25 literature 200C C 200 200°C 400C 400 800C 800 800°C standards guidelines analyzed are mixture highperformance properties terms 5 cracks specimens kgm3 kgm kg m3 m kg/m3 2 20 40 80 kg/m 4 8

Abstract Montane ecosystems in South America harbor high levels of endemism typically with species that are often threatened. Here we investigated fruit and seed morphology, germination, and early growth parameters of Crinodendron brasiliense, an endangered and narrow endemic tree species of subtropical montane cloud forests in Southern Brazil. We obtained fruit and seed size and shape, number of lobes and number of seeds per fruit and evaluated germination and early growth parameters in a greenhouse. We tested the effect of different container types and parent plant on seed morphology, germination, and early growth. We also tested whether thermal scarification would improve germination rates. We showed that parent plant significantly influenced fruit and seed morphology as well as early growth rates. The germination rate of the species was extremely low (0.003–0.004 seeds per day), which may be one important underlying cause of its small population size and restricted distribution. Thermal scarification was ineffective to improve the germination of seeds. Unexpectedly, container type significantly affected germination success, as seeds in trays germinated faster and in higher rates than seeds planted in seedbeds. Such result suggests a higher soil moisture could improve germination success. Our study is the first documented propagation of the species and provides essential aspects on the reproductive biology and early development of Crinodendron brasiliense. We highlight the urgent need for further research and collaborative conservation initiatives to prevent the extinction of this species. threatened brasiliense Brazil shape greenhouse 0.003–0.004 00030004 0 003 004 (0.003–0.00 day, day , day) distribution Unexpectedly success seedbeds 0.003–0.00 0003000 00 (0.003–0.0 0.003–0.0 000300 (0.003–0. 0.003–0. 00030 (0.003–0 0.003–0 0003 (0.003– 0.003– 000 (0.003 0.003 (0.00 0.00 (0.0 0.0 (0. 0.

Resumen Investigamos la morfología de frutos y semillas, la germinación y los parámetros del crecimiento inicial de Crinodendron brasiliense, una especie arbórea en peligro de extinción y endémica de los bosques montanos del sur de Brasil. Obtuvimos el tamaño y la forma de frutos y semillas, el número de lóbulos por fruto y el número de semillas por fruto, además de evaluar los parámetros de germinación y crecimiento inicial – desconocidos para la especie. Demostramos que la planta madre influyó significativamente en la morfología de frutos y semillas, así como en las tasas de crecimiento inicial. La tasa de germinación de la especie fue extremadamente baja (0.003–0.004 semillas por día), lo que podría ser una causa importante para explicar su pequeño tamaño poblacional y restringida distribución. La escarificación térmica fue ineficaz para la germinación de semillas. Inesperadamente, el tipo de contenedor afectó significativamente el éxito de la germinación, ya que las semillas plantadas en bandejas germinaron más rápido y en tasas más altas que las semillas plantadas en semilleros. Tal resultado sugiere que una mayor humedad del suelo podría mejorar el éxito de la germinación. Nuestro estudio es el primer registro documentado de la propagación de esta especie y proporciona aspectos esenciales sobre la biología reproductiva y el desarrollo inicial de Crinodendron brasiliense. Destacamos la necesidad urgente de realizar más estudios e iniciativas de conservación colaborativas para evitar la extinción de esta especie. brasiliense Brasil 0.003–0.004 00030004 0 003 004 (0.003–0.00 día, día , día) distribución Inesperadamente semilleros 0.003–0.00 0003000 00 (0.003–0.0 0.003–0.0 000300 (0.003–0. 0.003–0. 00030 (0.003–0 0.003–0 0003 (0.003– 0.003– 000 (0.003 0.003 (0.00 0.00 (0.0 0.0 (0. 0.

Resumo Este artigo mobiliza os fundamentos do referencial teórico da Educação em Direitos Humanos para analisar a relação entre xenofobia e racismo contra estudantes imigrantes, à luz de uma experiência de pesquisa qualitativa realizada em uma escola de educação básica no município de São Paulo com expressiva presença de estudantes imigrantes. A pesquisa permitiu concluir que o racismo associado à xenofobia (denominado xenofobia racializada) determina as probabilidades de integração de estudantes imigrantes na escola pública. Essa desigualdade discriminatória apresenta-se como um grave e urgente desafio à Educação em Direitos Humanos, cobrando uma prática de currículo expressamente comprometido com a superação dessa injustiça nas escolas que recebem estudantes imigrantes. denominado racializada pública apresentase apresenta se

Abstract This study uses the Human Rights Education (HRE) theoretical framework to analyze the relation between xenophobia and racism against immigrant students. A qualitative research experiment was carried out in a municipal elementary school with a significant presence of immigrant students in the city of São Paulo. This research found that racism, associated with xenophobia (here referred to as racialized xenophobia), determines the chances of immigrant students being integrated into public schools. This discriminatory inequality poses a serious and urgent challenge for Human Rights Education, demanding a curricular practice that is expressly committed to overcoming this injustice in schools that receive immigrant students.

Resumo: Objetivo Os reservatórios artificiais desencadeiam várias mudanças em seus rios a jusante que dependem das características hidráulicas dos reservatórios. No entanto, seus múltiplos usos também podem fornecer recursos que influenciam os serviços ecossistêmicos que eles fornecem. Este estudo abordou a capacidade potencial de um reservatório Neotropical em capturar espécies químicas, com o objetivo de avaliar o papel desses ecossistemas na mitigação da poluição. Métodos A modelagem da capacidade de retenção foi examinada para um pequeno reservatório subtropical com alto tempo de retenção hidráulica (> 100 dias). As variações temporais de 9 variáveis físicas e químicas da água ao longo de um período de cinco anos foram usados para calcular o balanço de massa e determinar a capacidade retentiva (parâmetro alfa) do reservatório Itupararanga (estado de São Paulo, Brasil). Para explicar o balanço de massa de longo prazo dessas variáveis, foi assumido que o reservatório seja um sistema completamente misturado com uma entrada em degrau. Resultados Os maiores valores de assimilação (i.e., alta capacidade de retenção) ocorreram nos meses úmidos (até 500 mm) para todas as variáveis. Altos coeficientes de reação (k) e baixa descarga hidráulica sugerem que os processos de sumidouro prevalecem sobre os de exportação, principalmente para fósforo total. O padrão de precipitação mostrou menor importância para o aprisionamento dos elementos.

Abstract: Aim Man-made reservoirs lead to several changes in their downstream rivers that depend on the hydraulic characteristics of the reservoirs. However, their multiple uses can also provide facilities that influence the ecosystem services that they provide. This study addressed the potential ability of a Neotropical reservoir to trap chemical species aiming to assess the role of these ecosystems to mitigate pollution. Methods Retention capability modeling was examined for a small subtropical reservoir with high hydraulic retention time (> 100 days). The temporal ranges of 9 physical and chemical water variables over a five-year period were used to calculate the mass balance and to determine the retentive capability (alpha parameter) of the Itupararanga Reservoir (São Paulo State, Brazil). To explain the long-term mass balance of these variables, it was assumed that the reservoir is a completely mixed system with a step input. Results The highest values of parametrized alpha (high retention capability) occurred in wet months (up to 500 mm) for all variables. High reaction rate constants (k) and low hydraulic flushing suggested that sink processes prevail over the export ones, mainly for total phosphorus. The rainfall pattern showed minor importance for trapping elements. Conclusions In the Neotropics, hydraulic characteristics of the ecosystem (e.g., low area:volume ratio) are a tool for pollution management in man-made reservoirs.

Abstract In this article we propose to analyze the construction of time in the Conjunto vacío by Verónica Gerber Bicecci. Framed in the artistic productions of the second generation of post-dictatorship, we consider that the novel seeks to name one of the social and subjective effects of political exile as a result of the last Argentine military dictatorship: the disorder of time. Using the memory of forms elaborated by Didi‒Huberman, we identify those passages where the narrator illuminates the coexistence of heterogeneous times, an element that demonstrates the difficulty of constituting a progressive chronological narrative, while at the same time finding in the writing and the I draw the possibility of symbolically resolving these imbalances, of accompanying the limits of language.

ABSTRACT Objective: The present study aimed to evaluate glucose variability and hormonal responses during and after an aerobic exercise session performed after breakfast in type 2 diabetes patients treated with metformin. Materials and methods: In this quasi-experimental study individuals underwent clinical and laboratory evaluations and maximal exercise test. After two weeks an aerobic exercise session (30 minutes at 60%-70% of the peak heart rate) was performed. At rest, during and after the exercise session, glucose variability (mean amplitude glucose excursions, glucose coefficient of variation, and glucose standard deviation) and levels of plasma glucose, insulin, glucagon, and glucagon-like-peptide-1 were evaluated. Results: Thirteen patients were enrolled in the study. Plasma glucose increased at 15 minutes during the exercise session (244.6 ± 61.9 mg/dL), and decreased at 60 min after exercise (195.6 ± 50.0 mg/dL). Glucose variability did not show any difference before and after exercise. Insulin levels at 15 min [27.1 µU/mL (14.2-42.1)] and 30 min [26.3 µU/mL (14.6-37.4)] during the exercise were higher than those at fasting [11.2 µU/mL (6.7-14.9)] but decreased 60 minutes after exercise (90 minutes) [16.6 µU/mL (8.7-31.7)]. Glucagon levels did not show any difference. GLP-1 levels increased at 30 min [7.9 pmol/L (7.1-9.2)] during exercise and decreased 60 min after exercise (90 minutes) [7.7 pmol/L (6.8-8.5)]. Conclusion: Subjects with type 2 diabetes presented expected changes in insulin, glucagon and GLP-1 levels after breakfast and a single aerobic exercise session, not accompanied by glycemic variability changes.

RESUMO A perda em altura da crista óssea alveolar pós extração dentária torna a reabilitação da maxila posterior desafiadora devido à baixa densidade e atrofia ósseas, além da pneumatização do seio maxilar. A cirurgia sinusal previamente à instalação de implantes viabiliza a reabilitação implantossuportada. Esse estudo teve como objetivo apresentar um relato de caso clínico submetido à cirurgia de levantamento de seio maxilar pela técnica da janela lateral previamente à reabilitação com prótese suportada por implantes dentários, destacando a importância do planejamento para minimizar complicações transoperatórias. Esse é um relato de caso clínico de um paciente do sexo masculino, 59 anos de idade, assistido em uma Instituição de Ensino Superior Privada, com queixa de espaços edêntulos e desejo de reabilitação com implantes. Foi submetido ao planejamento reabilitador incluindo o tratamento cirúrgico de levantamento de seio maxilar bilateral pela técnica da janela lateral. O ganho ósseo foi confirmado pela tomografia computadorizada de feixe cônico após seis meses da abordagem cirúrgica do seio maxilar bilateralmente. O planejamento reabilitador da região posterior da maxila e a execução da cirurgia de levantamento de seio pela técnica da janela lateral de maneira criteriosa consiste em uma opção terapêutica previsível para os casos clínicos com necessidade de ganho ósseo em altura previamente à instalação de implantes dentários. O caso clínico apresentado demonstrou sucesso no ganho de volume ósseo na região posterior de maxila, sem complicações pós-operatórias e o paciente segue satisfeito com o tratamento proposto, aguardando conclusão da reabilitação implantossuportada.

ABSTRACT The loss in height of the alveolar bone crest after tooth extraction makes rehabilitation of the posterior maxilla challenging due to low bone density and atrophy, in addition to pneumatization of the maxillary sinus. Maxillary sinus lift surgery prior to implant placement makes implant-supported rehabilitation feasible. This study aimed to describe a case report of maxillary sinus surgery using the side window technique prior to rehabilitation with a prosthesis supported by dental implants, highlighting the importance of planning to minimize intraoperative complications. This is a clinical case report of a 59-year-old male patient who was assisted at a private higher education institution complaining of edentulous spaces and the desire for rehabilitation with implants. He underwent rehabilitation planning, including the surgical treatment of maxillary sinus lifting using the side window technique. Bone gain was confirmed using cone beam computed tomography six months after the surgical approach to the maxillary sinus. The planning of rehabilitation of the posterior maxilla and careful sinus lift surgery using the side window technique is a predictable therapeutic option for clinical cases with bone gain in height of the posterior region of the maxilla prior to the installation of dental implants. The clinical case presented demonstrated success in the gain of bone volume in the posterior region of the maxilla, without postoperative complications, and the patient was still satisfied with the proposed treatment, awaiting complete implant-supported rehabilitation.

ABSTRACT The improvement of carbon (C) accumulation in soils has been one of the main purposes of the conservation systems in agricultural production. This study aimed to assess the long-term effect of conventional tillage (CT) and no-tillage (NT) combined with winter cover crops, black oat and oilseed radish, and fallow on C accumulation and stabilization in a very clayey Oxisol in Southern Brazil. Soil samples were collected in the 0-0.05, 0.05-0.10 and 0.10-0.20 m layers of a 26-year-old experiment. Distribution of size-class aggregates, C stock in aggregates, total C stock, and C stocks in the physical fractions, free particulate organic matter (free-POM), occluded particulate organic matter (occluded-POM) and mineral-associated organic matter (min-OM) were assessed. NT had a higher percentage of macroaggregates and C stock in this size-class, and also higher C stock in bulk soil, free-POM and occluded-POM fractions than CT in 0-0.05 m (Tukey’s test p < 0.05), due to higher input of biomass and minimum soil mobilization in NT. Oat and radish had higher C stock in macroaggregates than fallow in 0.05-0.10 m (Tukey’s test p < 0.05). Radish had the highest C stock in the free-POM (0-0.05 m). Fallow decreased the stabilization of macroaggregates and C accumulation in free-POM, due to the lower C input from aboveground biomass over the years. In conclusion, NT after 26 years improved C accumulation and stabilization, mainly in the superficial layer and in POM fractions, and winter cover crops favored the formation and stability of macroaggregates.

Resumo Pesquisas indicam a disseminação, pelo jornalismo industrial, de estereótipos e visões discriminatórias que tendem a não favorecer políticas de afirmação de direitos dos povos originários no Brasil. Nota-se, no entanto, a escassez de estudos sobre como os povos originários têm explorado as tecnologias para se comunicar e enfrentar tais visões. Este artigo busca contribuir para suprir essa lacuna, ao apresentar os resultados de um estudo sobre o tema, que teve o objetivo de produzir conhecimento científico sobre a presença na rede social Instagram do coletivo de indígenas Mídia Índia, por meio da metodologia de análise da narrativa aplicada sobre 31 postagens selecionadas de 2019 que dialogam com estereótipos e visões pejorativas hegemônicas. Os resultados sugerem que o movimento se diferencia por dialogar de forma criativa com estereótipos, questionando-os de modo a suscitar reflexões e desconstruções.

Abstract Studies show that the dissemination of discriminatory views and stereotypes by commercial media do not go towards defending the rights of native peoples in Brazil. However, there are few studies on how native peoples use technologies to communicate and deal with such discrimination. This article looks to fill this gap by presenting the results of a study on the subject, aimed at producing scientific knowledge about the indigenous network known as Mídia India and their presence on Instagram. We achieved this by conducting a narrative analysis of 31 posts from 2019 in response to stereotypes and hegemonic degrading views. The results suggest that this network differs itself by holding constructive dialogues about stereotypes and questioning them in order to generate serious thought and deconstruct the stereotypes.

Se observa, sin embargo, la falta de estudios sobre cómo los pueblos originarios han explorado las tecnologías para comunicarse y enfrentar tales visiones. Este artículo busca contribuir para rellenar ese vacío, al presentar los resultados de un estudio sobre el tema, produciendo conocimiento científico sobre la presencia en la red social Instagran del colectivo de indígenas Mídia Índia, por medio de la metodología de análisis de la narrativa aplicada sobre 31 publicaciones de 2019 que dialogan con estereotipos y visiones despectivas hegemónicas. Los resultados indican que el movimiento se diferencia por dialogar de forma creativa con estereotipos, cuestionándolos de modo a promover reflexiones y deconstrucciones.

RESUMO O presente artigo teve como objetivo o estudo de argamassa autoadensável com composições de agregado miúdo (areia de rio e areia de britagem) com intuito de reduzir o consumo de areia natural de rio, uma vez que a mesma gera um impacto devido a sua extração. No estado fresco, as argamassas produzidas foram avaliadas quanto à densidade de massa, teor de ar incorporado, fluidez e análise de borda. No estado endurecido foram determinadas as resistências à tração e à compressão; o módulo de elasticidade dinâmico e a densidade de massa aparente. A partir dos resultados obtidos concluiu-se que a substituição de areia natural de rio por areia de britagem diminuiu a demanda de água nas argamassas autoadensáveis, resultando num aumento do consumo de cimento Portland por m3, em um menor volume de pasta para a mesma fluidez, isso devido ao maior módulo de finura da areia de britagem e melhor empacotamento em função da granulometria mais contínua. Com a diminuição da relação água/cimento houve um aumento dos valores de resistência à compressão e à tração e do módulo dinâmico, obtendo valores acima do mínimo exigido por norma. Como o consumo de cimento Portland por m3 também aumentou, evidencia-se a possibilidade de ajuste na composição reduzindo o seu consumo para uma dada resistência. Assim, com o aumento do teor de areia de britagem e de cimento Portland, as argamassas obtiveram um menor índice de intensidade de ligante, assim mais eficientes. extração fresco incorporado borda aparente concluiuse concluiu se autoadensáveis m contínua águacimento norma aumentou evidenciase evidencia Assim ligante eficientes

ABSTRACT This article aimed to study self-compacting mortar with fine aggregate compositions (river sand and crushed sand) in order to reduce the consumption of natural river sand, since it generates an impact due to its extraction. In the fresh state, the mortars produced were evaluated for specific gravity, air entrained content, fluidity and appearance (surface finish). In the hardened state were also determined the tensile and compressive strengths; elasticity modulus and specific gravity. From the results obtained, it was concluded that the replacement of natural river sand by crushing sand reduced the water demand in self-compacting mortars (higher cement consumption), resulting in a lower volume of paste for the same fluidity, due to the greater fineness modulus of sand from crushing and better packing due to more continuous granulometry. The decrease in the water-cement ratio resulting in an increase in the compressive strength, tensile strength and the elasticity modulus, obtaining values above the minimum required by standard specification. However, as the consumption coefficient of Portland cement has also increased, the possibility of adjusting the composition is evident, reducing the consumption coefficient of Portland cement for a given strength. With the increase in the crushing sand and Portland cement content, the mixtures obtained a lower binder intensity index, more efficient. selfcompacting self compacting extraction gravity content surface finish. finish . finish) strengths higher consumption, , consumption) granulometry watercement specification However increased evident index efficient

ABSTRACT Objective To compare the major outcomes of use of metformin and glyburide in treatment of gestational diabetes mellitus. Methods Studies published in English, in the last 10 years, in the databases MEDLINE®, SciELO, LILACS and Cochrane Library were analyzed, and randomized controlled trials were selected. Health Sciences Descriptors were used to compose the search phrase, and the keywords “Gestational diabetes”, “Glyburide”, “Metformin” and their variations were searched in the Medical Subject Headings. PRISMA systematization was used to prepare this review, and a meta-analysis was conducted aiming to mathematically show the results of fasting blood glucose, postprandial blood glucose, birth weight and weight gain during pregnancy after using metformin and glyburide. Results The studies evaluated birth weight, neonatal hypoglycemia, mode of delivery, need for intensive care, Apgar score, macrosomia, fasting glucose, postprandial glucose and weight gain during pregnancy. In 60% of studies, there were no statistically significant differences regarding safety and efficacy of administration of metformin and glyburide. Meta-analysis demonstrated the absence of statistical differences between these drugs in fasting blood glucose (p=0.821), postprandial blood glucose (p=0.217) and birth weight (p=0.194). However, significant differences were shown in weight gain during pregnancy (p=0.036). Conclusion The methods are effective, but the adverse effects of glyburide are more common; therefore, the use of metformin should be recommended, if in monotherapy.
