Rupturas e transições na trajetória acadêmica de licenciado(a)s em música em contexto pandêmico
The situation imposed by the COVID-19 pandemic, with the suspension of face-to-face classes indefinitely, led to the implementation of Emergency Remote Teaching (ERT) in all educational institutions in the country. This study sought to understand how the dynamics of the transition from face-to-face to remote teaching and from the later to the former took place, in the Teaching Training Music Course at IFPE Campus Belo Jardim, focusing on learning the musical instrument. We adopted the theoretical-methodological assumption of Semiotic Cultural Psychology, in particular, we resorted to the concepts of rupture and transition and to the three levels of meanings
(semantic, pragmatic, and existential) proposed to understand learning as meaning making. This longitudinal study used two online questionnaires applied at different times: during remote teaching and when returning to face-to-face teaching. The analysis was carried out in an interpretative way, in the light of cultural psychology. Through the mapped meanings, it was possible to identify the tensions and fears experienced by students in the transition periods from face-to-face teaching to remote teaching and from remote back to face-to-face teaching. Also, the meanings built on the facilities and difficulties faced in the transition processes. We also suggested new studies that explore what would have been the learnings built-in remote teaching that was incorporated into post-pandemic face-to-face teaching.A situação imposta pela pandemia da COVID-19, com a suspensão das aulas presenciais por tempo indefinido, trouxe a implantação do Ensino Remoto Emergencial (ERE) em todas as instituições de ensino do país. Este estudo buscou compreender como se deu a dinâmica da transição do ensino presencial para o remoto e deste para o
presencial, no curso de Licenciatura em Música do IFPE Campus Belo Jardim, focalizando a aprendizagem do instrumento musical. Adotamos o pressuposto teórico-metodológico da Psicologia Cultural Semiótica, em especial recorremos aos conceitos de ruptura e transição e aos três níveis de significados (semântico, pragmático e existencial) propostos para compreender a aprendizagem como construção de significados. Este estudo, de caráter longitudinal, utilizou dois questionários online aplicados em tempos distintos: durante o ensino remoto e no retorno ao ensino presencial de música. A análise foi feita de forma interpretativa, à luz do referencial teórico da psicologia cultural. Através dos significados mapeados, foi possível identificar as tensões e medos experiencia dos pelos estudantes nos períodos de transição do ensino presencial para o ensino remoto e do remoto de volta ao presencial. Também os significados construídos sobre as facilidades e dificuldades enfrentadas nos processos de transição. Novos estudos que explorem quais teriam sido os aprendizados construídos no ensino remoto que foram incorporados ao ensino presencial pós-pandemia foram sugeridos

Rainfall in the urban area and its impact on climatology and population growth
Due to the scarcity of studies linking the variability of rainfall and population growth in the capital cities of Northeastern Brazil (NEB), the purpose of this study is to evaluate the variability and multiscale interaction (annual and seasonal), and in addition, to detect their trends and the impact of urban growth. For this, monthly rainfall data between 1960 and 2020 were used. In addition, the detection of rainfall trends on annual and seasonal scales was performed using the Mann–Kendall (MK) test and compared with the phases of El Niño-Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO). The relationship between population growth data and rainfall data for different decades was established. Results indicate that the variability of multiscale urban rainfall is directly associated with the ENSO and PDO phases, followed by the performance of rain-producing meteorological systems in the NEB. In addition, the anthropic influence is shown in the relational pattern between population growth and the variability of decennial rainfall in the capitals of the NEB. However, no capital showed a significant trend of increasing annual rainfall (as in the case of Aracaju, Maceió, and Salvador). The observed population increase in the last decades in the capitals of the NEB and the notable decreasing trend of rainfall could compromise the region’s water security. Moreover, if there is no strategic planning about water bodies, these changes in the rainfall pattern could be compromising
Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Curcumin and Quercetin-Loaded Lipid Nanocarriers: Development of Omega-3 Mucoadhesive Nanoemulsions for Intranasal Administration
Curcumin (CUR) and quercetin (QU) are potential compounds for treatment of brain diseases such as neurodegenerative diseases (ND) because of their anti-inflammatory and antioxidant properties. However, low water solubility and poor bioavailability hinder their clinical use. In this context, nanotechnology arises as a strategy to overcome biopharmaceutical issues. In this work, we develop, characterize, compare, and optimize three different omega-3 (omega-3) fatty acids nanoemulsions (NEs) loaded with CUR and QU (negative, cationic, gelling) prepared by two different methods for administration by intranasal route (IN). The results showed that formulations prepared with the two proposed methods exhibited good stability and were able to incorporate a similar amount of CUR and QU. On the other side, differences in size, zeta potential, in vitro release kinetics, and permeation/retention test were observed. Considering the two preparation methods tested, high-pressure homogenization (HPH) shows advantages, and the CQ NE- obtained demonstrated potential for sustained release. Toxicity studies demonstrated that the formulations were not toxic for Caenorhabditis elegans. The developed omega-3 fatty acid NEs have shown a range of interesting properties for the treatment of brain diseases, since they have the potential to increase the nose-to-brain permeation of CUR and QU, enabling enhanced treatments efficiency
Chronic total occlusion percutaneous coronary intervention in Latin America
Objectives To report clinical, angiographic characteristics, outcomes, and predictors of unsuccessful procedures in patients who underwent chronic total occlusion (CTO) percutaneous coronary interventions (PCI) in Latin America. Background CTO PCI has been increasingly performed worldwide, but there is a lack of information in this region. Methods An international multicenter registry was developed to collect data on CTO PCI performed in centers in Latin America. Patient, angiographic, procedural and outcome data were evaluated. Predictors of unsuccessful procedures were assessed by multivariable analysis. Results We have included data related to 1,040 CTO PCIs performed in seven countries in Latin America (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, and Puerto Rico). The mean age was 64 +/- 10 years, and CTO PCI was performed mainly for angina control (81%) or treatment of a large ischemic area (30%). Overall technical success rate was 82.5%, and it was achieved with antegrade wire escalation in 81%, antegrade dissection/re-entry in 8% and with retrograde techniques in 11% of the successful procedures. Multivariable analysis identified moderate/severe calcification, a blunt proximal cap and a previous attempt as independent predictors of unsuccessful procedures. In-hospital major adverse cardiovascular events (MACE) occurred in 3.1% of the cases, death in 1% and cardiac tamponade in 0.9% Conclusions CTO PCI in Latin America has been performed mainly for ischemia relief. Procedures were associated with a success rate above 80% and low incidence of MACE. Predictors of unsuccessful procedures were similar to those previously reported in the literature.Brazilian Society of Interventional Cardiolog
