    This article is about Saeb - Sistema de Avaliação da Educação Básica (Basic Education Assessment System), in view of its impact on the (re)formulation of educational public policies in Brazil. As a precursor to students and educational networks performance admeasurement exams, we seek to discuss the official documents that deal with the organization, characteristics and functions of Saeb, through research and documental analysis of the Reference Documents - Version 1.0 (2018). The results indicate that Saeb brings with itself nuances of neoliberal ideology by establishing a pattern of competence to be achieved by students, disregarding the social context in which they are inserted, as well as submitting to the logic of productivity, with a consequent ranking of participating schools. The study points out that evaluation mechanisms must guarantee quality teaching for all, respecting the specific needs of each student and school, as well as quantitative data must be used as decision-making tools for pedagogical practices.Este artículo trata sobre el Sistema de Evaluación de la Educación Básica (Saeb), en vista de su impacto en la (re) formulación de las Políticas Públicas Educativas en Brasil. Como precursor de los exámenes para medir el desempeño de los estudiantes y las redes educativas, se buscó analizar los documentos oficiales que abordan la organización, características y funciones del Saeb, a través del análisis documental de benchmarks - Versión 1.0 (2018), acompañado de una revisión de la literatura. Los resultados indican que el Saeb trae consigo matices de ideología neoliberal al establecer un patrón de competencia a alcanzar por los estudiantes, desconociendo el contexto social en el que se insertan, además de someterse a la lógica de la productividad, con una consecuente clasificación de escuelas participantes. El estudio señala que los mecanismos de evaluación deben garantizar una enseñanza de calidad para todos, respetando las necesidades específicas de cada alumno y escuela, así como los datos cuantitativos deben ser utilizados como toma de decisiones para las prácticas pedagógicas.O presente artigo versa sobre o Sistema de Avaliação da Educação Básica (Saeb), tendo em vista sua incidência na (re)formulação de Políticas Públicas Educacionais no Brasil.

    Teeth with open apices, such as in immature teeth or those with apical root resorption are clinical cases with difficult immediate resolution. With the use of mineral trioxide aggregate (MTA) in dentistry, it was possible to optimize the treatment time of these cases by immediate placement of apical plug and the root canal filling. However, some negative effects can occur if MTA is extruded beyond the apex. To avoid this accident, it has been recommended to use of an apical matrix prior to placement of MTA. This study reports two clinical cases of apical plug placement in teeth with pulp necrosis and open apices. One case had an immature apex due to dental trauma and the other case had apical resorption due to the presence of endodontic infection in the root canal. MTA apical plug with approximately 4 mm thickness, was placed in the apical zone of the root and immediately the canal was obturated with gutta-percha and endodontic sealer. Follow-up evaluations showed clinical and radiographic evidence of success.Keywords: Apex; Collagen; Endodontics; Mineral Trioxide Aggregat

    Renal ischemia and reperfusion (I/R) is the major cause of acute kidney injury in hospitalized patients. Mechanisms underlying reperfusion-associated injury include recruitment and activation of leukocytes and release of inflammatory mediators. In this study, we investigated the renal effects of acute administration of AVE0991, an agonist of Mas, the angiotensin-(1–7) receptor, the angiotensin-(1–7) receptor, in a murine model of renal I/R. Male C57BL/6 wild-type or Mas−/− mice were subjected to 30 min of bilateral ischemia and 24 h of reperfusion. Administration of AVE0991 promoted renoprotective effects, as seen by improvement of function, decreased tissue injury, prevention of local and remote leucocyte infiltration, and release of the chemokine, CXCL1. I/R injury was similar in WT and Mas−/− mice, suggesting that endogenous activation of this receptor does not control renal damage under baseline conditions. In conclusion, pharmacological interventions using Mas receptor agonists may represent a therapeutic opportunity for the treatment of renal I/R injury

    The port of Recife in northeastern Brazil is an important ecological and social area but little is known about its environmental quality. Observations, sampling and measurements of phytoplankton were performed during spring and neap tides in the dry (January-February, 2005) and rainy (June, 2005) seasons to assess the environmental quality of the port of Recife. The area had chlorophyll-a concentrations ranging from 3.30 to 54.40 mg m-3, the highest values occurring at low tide during the dry season. A total of 129 species were identified: 53 of them in the dry season and 97 in the rainy season. Diatoms were the most diverse group and comprised 75.47% of the phytoplankton collected in the dry season and 60.82% of those collected in the rainy season. The dry season was characterized by Coscinodiscus sp. and Helicotheca tamesis; the rainy season by Oscillatoria sp. and Coscinodiscus centralis. Species diversity indices varied from 1.06 to 3.74 bits cel-1. Low indices were related to the dominance of Helicotheca tamesis, Coscinodiscus centralis, Coscinodiscus sp. and Aulacoseira granulata. Seasonal forcing, rather than the estuarine flux, determined the phytoplankton community structure. The area is exposed to seasonally varying negative impacts due to metropolitan degradation and the high level of eutrophication.Para avaliar a qualidade ambiental Porto do Recife (Nordeste do Brasil), uma área ecológica e socialmente importante mas pouco investigada, observações, medições e amostragem do fitoplâncton foram realizadas durante as marés de sizígia e quadratura no período de estiagem (janeiro-fevereiro / 2005) e chuvoso (junho/2005). A área apresentou concentração de clorofila a variando de 3,30 a 54,40 mg m-3, com maiores valores registrados durante a maré baixa no período de estiagem. Um total de 129 espécies foi identificada com 53 espécies durante o período de estiagem e 97 espécies no chuvoso. As diatomáceas formaram o grupo mais diverso, com 75,47% no período de estiagem e 60,82% no chuvoso. Coscinodiscus sp. e Helicotheca tamesis caracterizaram o período de estiagem e Oscillatoria sp. e Coscinodiscus centralis o período chuvoso. A diversidade de espécie variou de 1,06 a 3,74 bits cel-1 . Os baixos índices foram relacionados com a dominância de Helicotheca tamesis, Coscinodiscus centralis, Coscinodiscus sp. e Aulacoseira granulata. A sazonalidade determinou a estrutura da comunidade fitoplanctônica, em vez do fluxo estuarino. A área é exposta sazonalmente a vários impactos negativos, devido à degradação metropolitana e ao elevado nível de eutrofização

    South America holds 30% of the world's avifauna, with the Atlantic Forest representing one of the richest regions of the Neotropics. Here we have compiled a data set on Brazilian Atlantic Forest bird occurrence (150,423) and abundance samples (N = 832 bird species; 33,119 bird individuals) using multiple methods, including qualitative surveys, mist nets, point counts, and line transects). We used four main sources of data: museum collections, on-line databases, literature sources, and unpublished reports. The data set comprises 4,122 localities and data from 1815 to 2017. Most studies were conducted in the Florestas de Interior (1,510 localities) and Serra do Mar (1,280 localities) biogeographic sub-regions. Considering the three main quantitative methods (mist net, point count, and line transect), we compiled abundance data for 745 species in 576 communities. In the data set, the most frequent species were Basileuterus culicivorus, Cyclaris gujanensis, and Conophaga lineata. There were 71 singletons, such as Lipaugus conditus and Calyptura cristata. We suggest that this small number of records reinforces the critical situation of these taxa in the Atlantic Forest. The information provided in this data set can be used for macroecological studies and to foster conservation strategies in this biodiversity hotspot.
