Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by extracellular accumulation of amyloid-β (Aβ) peptides in the brain. This study demonstrates the direct association of the disposable pipette extraction (DPX) with tandem mass spectrometry (MS/MS) for the analysis of Aβ peptides in cerebrospinal fluid (CSF) samples. Different parameters were optimized in order to improve detectability in the MS/MS including mobile phase percentage of ammonium hydroxide, mobile phase flow rate and acquisition mode. Also, this method used an electrospray ionization (ESI) low-flow probe and direct infusion of an organic solution in the MS/MS. The DPX-MS/MS method showed adequate linearity for determining Aβ peptides in CSF-linearity ranged from 0.1 to 1.5 ng mL 1. The coefficients of determination were higher than 0.99; the precision coefficient of variation (CV) ranged from 0.3 to 12.7%; and the accuracy relative standard deviation (RSD) ranged from -13.6 to 13.2%.

Over the last two decades, metabolomics has emerged as a pivotal tool in multidisciplinary research, providing invaluable insights into metabolome modulations and finding applications across various scientific domains, including medicine and agronomy. Nonetheless, the absence of standardized procedures in sample preparation, data acquisition, and documentation of data quality presents a significant challenge. This review underscores the critical importance of quality assurance and quality control (QA/QC) in untargeted metabolomics, advocating for the establishment of agreed-upon QA/QC reporting standards within the scientific community. We discuss the requisite quality controls at various stages of untargeted metabolomics studies, encompassing blank samples, pooled samples, and the utilization of external quality control samples. Methods for assessing accuracy, reproducibility, and identifying/correcting batch effects are addressed. Furthermore, emphasis is placed on standardizing the description of QA/QC data in scientific publications and repositories to foster reproducibility and transparency. We recommend the publication of QC data alongside studies in appropriate databases to facilitate data comparison and sharing among researchers, thereby enhancing the quality of untargeted metabolomics research. In summary, implementing standardized QA/QC data reporting, along with promoting best practices within the untargeted metabolomics community, is crucial for improving result quality and credibility and advancing research utilizing this powerful technique. decades domains agronomy Nonetheless preparation acquisition challenge QAQC QA (QA/QC agreedupon agreed upon community samples accuracy identifyingcorrecting identifying correcting addressed Furthermore transparency researchers summary technique

RESUMO: O ensino de anatomia vem se modificando ao longo dos anos, introduzindo métodos tecnológicos, principalmente após o período pandêmico. Questiona-se o uso exclusivo da tecnologia em comparação aos métodos tradicionais de dissecação e aulas teóricas presenciais no que diz respeito à aquisição de conhecimento. Este artigo analisou a percepção de conhecimento de alunos de diversos semestres do curso de Medicina Veterinária, comparando alunos que tiveram aulas apenas online com aqueles que tiveram aulas presenciais de Anatomia Descritiva dos Animais Domésticos. Para tanto, questões foram enviadas por meio de formulário, com preenchimento voluntário e anônimo, e posteriormente analisadas estatisticamente. Os resultados indicam que 11,5% dos alunos que cursaram a disciplina remotamente falharam na aplicação dos conhecimentos em outras disciplinas, enquanto nenhum aluno do ensino presencial relatou o mesmo. A maioria dos alunos, tanto dos grupos remotos quanto dos presenciais, lembram-se do assunto, mas revisam o conteúdo com frequência. Em relação ao conhecimento teórico, o grupo online (80,8%) compreendeu melhor à medida que o curso avançava, comparado a 59,6% do grupo presencial. A ligação entre Anatomia e outras disciplinas foi mais destacada pelo grupo presencial (30,8%) em comparação ao online (15,4%). Ambos os grupos concordam que o contacto físico com peças anatômicas é essencial, mas alguns consideram possível ter um primeiro contacto com imagens ou fotografias 3D. Baseado nesse estudo preliminar, conclui-se que as interações iniciais com a área de Anatomia devem incluir técnicas pedagógicas diversificadas com comunicação empática. A utilização de recursos tecnológicos modernos é um aliado do processo de ensino-aprendizagem, e após a abstração dos conteúdos é possível o uso singular da tecnologia na manutenção e atualização do conhecimento anatômico.

ABSTRACT: Anatomy teaching has been changing over the years, introducing technological methods especially after the pandemic period. An ongoing debate revolves around whether exclusive reliance on technology for anatomy classes, as opposed to traditional methods and face-to-face instruction, enhances knowledge acquisition. This study analyzed the knowledge perception of students from various semesters throughout the Veterinary Medicine course, comparing students who only had online classes with those who had face-to-face classes in Gross Anatomy of Domestic Animals. For this purpose, a questionnaire was distributed for voluntary and anonymous completion, and the responses were subsequently analyzed statistically. The results indicated that 11.5% of the students who took Anatomy remotely failed to apply the knowledge in other subjects, while no face-to-face learning student reported the same. Most students, both remote and face-to-face groups, remember the subject but review the content frequently. Regarding theoretical knowledge, the online group (80.8%) understood better as the course progressed, compared to 59.6% of the face-to-face group. The connection between Anatomy and other subjects was more highlighted by the face-to-face group (30.8%) compared to the online group (15.4%). Both groups agree that physical contact with anatomical specimens is essential; however, some believe that initial exposure through 3D images or photographs is feasible. We concluded based on this preliminary study that the initial interactions with the Anatomy field should include diversified pedagogical techniques with empathetic communication. The use of modern technological resources are allies in the teaching-learning process. Furthermore, after abstracting the contents, technology alone can effectively maintain and update anatomical knowledge.

Abstract The shear behavior of reinforced concrete beams, particularly those with steel fiber reinforced concrete (SFRC), remains a challenge for the scientific community, as it involves complex material behavior. However, the advancement of the digital image correlation (DIC) technique has facilitated the acquisition of essential experimental data for modeling the mechanical behavior of SFRC, contributing to a better understanding of the problem and the shear resistance mechanisms. In this study, eight reinforced concrete beams, with and without steel fibers, were evaluated using the DIC technique to quantify the resistance mechanisms, with a focus on models that may represent the contribution of the fibers. The results revealed that the predominant mechanisms in shear behavior were aggregate interlock and the steel fibers. This study also represents a step towards a more rational understanding of shear behavior, while identifying gaps that require further investigation, such as the influence of fibers on all resistance mechanisms and the formulation of the contribution of steel fibers. beams SFRC , (SFRC) community However (DIC investigation (SFRC

Resumo O entendimento do comportamento à força cortante de vigas de concreto armado, especialmente as vigas de concreto reforçado com fibras de aço (CRFA), ainda é um desafio para a comunidade científica, devido à complexidade do comportamento dos materiais. No entanto, a evolução da técnica de correlação por imagem digital (CID) permitiu a obtenção de dados experimentais fundamentais para a modelagem do comportamento mecânico do CRFA, contribuindo para um melhor entendimento do problema e dos mecanismos resistentes à força cortante. Neste sentido, o presente estudo avalia oito vigas de concreto armado, com e sem fibras de aço, utilizando a técnica CID para quantificar os mecanismos resistentes, com foco nos modelos que podem representar a contribuição das fibras. Os resultados revelaram que os mecanismos preponderantes no comportamento à força cortante foram o engrenamento dos agregados e as fibras de aço. Este estudo representa um avanço no entendimento mais racional do comportamento à força cortante, assim como identifica lacunas que requerem estudos mais aprofundados, como a influência das fibras em todos os mecanismos resistentes e a formulação da contribuição das fibras de aço. armado CRFA , (CRFA) científica materiais entanto (CID sentido aprofundados (CRFA

Abstract The aim of the present study was to analyze the influence of caregivers' verbal production on the lexical production of infants (30 to 48 months), through a joint reading task. Method: 249 dyads (caregiver-infant) participated and the units of analysis type (number of different words produced without repetition) and token (total number of words produced) were used. Statistically significant correlations were observed in all grammatical categories produced by the dyads, as well as the effect of the caregiver's verbal production on that of the infant. The results highlight the importance and influence of caregivers on children's verbal production, with adults' verbal production being a significant predictor of the language development of infants between three and four years of age when interacting in joint reading contexts.

Se observaron correlaciones estadísticamente significativas en todas las categorías gramaticales producidas por las diadas, así como el efecto de la producción verbal del cuidador sobre la del infante. Los resultados resaltan la importancia e influencia de los cuidadores sobre la producción verbal infantil, siendo la producción verbal de los adultos un predictor significativo del desarrollo de lenguaje de infantes entre tres y cuatro años cuando interactúan en contextos de lectura conjunta.

Abstract: The curriculum of engineering careers includes training in basic sciences and engineering sciences. This analysis addresses research that applies active methodologies to teaching engineering as a formative ex- perience. The information collected in the Web of Science, Scopus and SciELO databases, under the PRISMA model of systematic literature review, analyzed the active methodologies, evaluation tools and their curricular approach and impact. A total of 646 articles were obtained, of which only 85 were selected according to the inclusion and exclusion criteria. The research focuses on engineering subjects taught through cooperative learning and project-based learning, using data collection techniques such as questionnaires and surveys focused on the experience of innovation. The effects of pedagogical choices are focused on academic achievement and content acquisition. In conclusion, the relationship between the teaching object and the subjects is mediated by learning experiences in which curriculum, didactics, and evaluation interact. This allows students to map a formative experience aimed at subjectivation, that is, reconstructing their vision of the world at both the personal and professional levels.

Abstract Before the arrival of the communicative approach in our classrooms, the teaching and the learning of vocabulary was based on memorising lists of words in written form. From then on, students had to learn how to pronounce them. This resulted in correct spelling and poor pronunciation. With the introduction of the communicative approach, the focus has been on oral learning of vocabulary and thus pronunciation has improved, but correct spelling has been lost in many cases. In this paper we present the results of a cross-sectional study of errors and correct productions of nine nouns at the end of primary, compulsory secondary and baccalaureate education. For this purpose, we have used a corpus created in the Canary Islands, representative of the students of the seven islands, which includes a sample of essays written in English. The results show a decrease in errors. In conclusion, we can see that most of the errors are of an intralinguistic type, being mostly writing hypotheses that the pupil uses in order to internalise the process of reading and writing in English.

Resumen Antes de la llegada del enfoque comunicativo a nuestras aulas, la enseñanza y el aprendizaje del vocabulario se basaba en la memorización de listados de palabras en su forma escrita y a partir de ahí el alumnado debía ir aprendiendo a pronunciarlas. Todo ello tenía como consecuencia una correcta ortografía y una pésima pronunciación. Con la introducción del enfoque comunicativo, el objetivo ha sido el aprendizaje oral del vocabulario y con ello se ha mejorado la pronunciación, pero se ha perdido la corrección ortográfica en muchos casos. En este trabajo presentamos los resultados de un estudio transversal de los errores ortográficos y producciones correctas en nueve sustantivos al final de la Educación Primaria, Secundaria Obligatoria y Bachillerato. Para este fin hemos utilizado un corpus creado en Canarias, representativo del alumnado de las siete islas, en el que se recoge una muestra de redacciones escritas en inglés. Los resultados presentan una disminución de errores ortográficos. Como conclusión podemos comprobar que la mayoría de los errores ortográficos son de tipo intralingüístico, pues casi todos son hipótesis de escritura que el alumno utiliza para así ir interiorizando el proceso de lectoescritura inglesa.

Resumen El objetivo de esta investigación cualitativa es identificar los factores que facilitan u obstaculizan la adquisición o el fortalecimiento de competencias culturales en la labor de los profesionales de atención primaria de salud en Chile. Con base en las entrevistas semiestructuradas realizadas a 32 profesionales que trabajan en una comuna de Santiago, se efectuó un análisis de contenido considerando cuatro dimensiones de las competencias culturales: conciencia, conocimiento, habilidades y motivación. Este análisis fue discutido en ocho conversatorios con profesionales de atención primaria, académicos/as e integrantes de colectivos migrantes; esto permitió reconocer los patrones en el trato y en la atención que avalan ciertas prácticas y valores. Se concluye que los factores analizados interpelan a los/as profesionales y constituyen un insumo para estimular los procesos de reflexión individual y de los equipos.

ABSTRACT This research was conducted in the rural areas of Clara and La Hilera, Tacuarembó, Uruguay. The objective was to understand the impact of the COVID-19 pandemic on the food situation of households in these communities with dispersed population characteristics, from a human right to food perspective. A cross-sectional mixed descriptive study was conducted. Data were collected using the ELCSA scale, non-participant observations, semi-structured interviews with adults responsible for household food provision, and in-depth interviews with qualified informants from both areas. The results show that the level of household food insecurity remained the same in half of the households before and after the onset of the pandemic. It is concluded that the pandemic did not cause changes in the acquisition and local availability of food in almost all households.

It also investigates the effects of this immersive environment on students with different proficiency levels, elementary and intermediate levels. Theoretically, the study is based on the assumptions of the Embodied Cognition theory, which considers the mind and our bodily experiences with the external world as central elements in the processing and acquisition of knowledge. In the methodological scope, the Augmented Reality environment used in this research was applied to 15 students of Ensino Técnico Integrado ao Ensino Médio do IFRJ, campus Eng. Paulo de Frontin and the data collected were generated through vocabulary tests and a questionnaire. The results indicate that the Augmented Reality environment can significantly contribute to vocabulary learning in the short and long term, especially for intermediate level students who benefited the most from the tested environment. education ESLEFL ESL EFL longterm term levels Theoretically theory knowledge scope 1 IFRJ Eng questionnaire

Zusammenfassung: Ziel dieser quantitativen Studie ist es, die Korrelation zwischen den L2-Lernstrategien von Deutschlernenden und der Beherrschung der Nebensatzsyntax bei deutschen Verben festzustellen. Zur Messung der Lernstrategien wurde die Version 7 des Oxford SILL (Oxford, 2003) verwendet. Die Forced-Choice-Tests von Catasso (2004) wurden verwendet, um die Kenntnisse der Nebensatzsyntax zu beurteilen. Die Probanden an dieser Studie waren 55 Schüler einer deutschen Schule Chiles. Die mit R durchgeführte Analyse zeigt, dass die am häufigsten verwendete Lernstrategie die Kompensationsstrategien waren. Die Daten zeigten, dass keine statistisch signifikante positive Korrelation zwischen häufiger Lernstrategieanwendung und besserer Beherrschung der Verbstellung besteht. Es besteht jedoch eine statistisch signifikante negative Korrelation zwischen dem Einsatz metakognitiver Strategien und der Beherrschung der Nebensatzsyntax bei männlichen Lernenden. Die persönlichen Variablen beim Sprachenlernen könnten positive Auswirkungen haben. In Zukunft wäre es sinnvoll, diese Art von Korrelationsstudien auf andere Aspekte des deutschen Spracherwerbs wie die Deklination auszuweiten.

Abstract: The aim of this quantitative study is to determine the correlation between German learners' L2 learning strategies and their mastery of German verb subordinate clause syntax. To measure learning strategies, version 7 of the Oxford SILL (Oxford, 2003) was used. Catasso's (2004) forced-choice tests were used to assess knowledge of subordinate clause syntax. The subjects in this study were 55 students from a German school in Chile. The analysis carried out with R shows that the most frequently used learning strategy was the compensatory strategies. The data showed that there is no statistically significant positive correlation between frequent learning strategy use and better mastery of verb position. However, there is a statistically significant negative correlation between the use of metacognitive strategies and the mastery of subordinate clause syntax in male learners. Personal variables in language learning could have positive effects. In the future, it would be useful to extend this type of correlational study to other aspects of German language acquisition such as declension.

Abstract As a result of COVID-19, new dynamics emerged in many urban systems, including the acquisition and distribution of food. The pandemic revealed vulnerabilities in the functioning of facilities and intensified problems such as informality, insecurity, and immigration. In order to contribute to the identification and characterization of these dynamics within food markets, a case study methodology was adopted for this article using mixed techniques - a quantitative approach using a survey and a qualitative approach featuring a focus group. Both methods were applied in the San Roque market in the Metropolitan District of Quito, an iconic food market and distribution facility. The results highlight new commercial dynamics and preferences, as in recent years informal trade and the presence of supermarket chains have proliferated; new logistic means have been created; and wholesale trade has intensified. In addition, the pandemic accentuated the vulnerability of the market at the administrative level and the precariousness of some informal jobs, in turn, accelerated changes among traders. It is concluded that these dynamics merit new conceptual, organizational, and spatial approaches in architectural and urban terms, as well as different policies that favor the sustainable management of markets.

Resumen A raíz de la covid-19 se dieron nuevas dinámicas en muchos sistemas urbanos entre las que destaca la de adquisición y distribución de alimentos. La pandemia mostró la vulnerabilidad en el funcionamiento de equipamientos e intensificó problemáticas como la informalidad, la inseguridad y la inmigración. Con el objetivo de aportar a la identificación y caracterización de estas dinámicas dentro de los mercados de alimentos, para el presente artículo se adoptó una metodología de caso de estudio con técnicas mixtas: cuantitativas por medio de una encuesta y cualitativas a partir de un grupo focal. Ambas técnicas se aplicaron en el mercado San Roque en el Distrito Metropolitano de Quito, equipamiento icónico en cuanto a la comercialización y distribución de alimentos. En los resultados sobresalen las nuevas dinámicas y preferencias comerciales, ya que en los últimos años han proliferado el comercio informal y la presencia de cadenas de supermercados, se han creado nuevos medios logísticos y se ha intensificado el comercio mayorista. Además, la pandemia acentuó la vulnerabilidad del mercado a nivel administrativo y la precarización de algunos trabajos informales, a su vez, aceleró un cambio entre el grupo de comerciantes. Se concluye que estas dinámicas ameritan nuevas aproximaciones conceptuales, organizativas y espaciales a escala arquitectónica y urbana, y también distintas políticas que favorezcan la gestión sostenible de los mercados.
