Abstract Introduction : Electronic devices and communication technologies are increasingly used to provide medical care to patients with high blood pressure. The main objective was to evaluate doctors’ perception on the usefulness of digital technologies in hypertension. The secondary objectives were to evaluate the prevalence of use of digital technologies in the follow-up of patients with hypertension and to identify the barriers perceived by doctors for their implementation in the Argentine Republic. Methods : Observational, cross-sectional, multicenter study, based on a self-administered questionnaire, in the Argentine Republic, and coordinated by the Epidemiol ogy group of the Argentine Society of Arterial Hyper tension. Population: Doctors who care for patients with high blood pressure. Results : 247 responses were obtained, 35.6% were women and 64.4% men; 92.3% indicated that the use of digital technologies was useful to improve therapeutic adherence; 54.7% received blood pressure results at home through some digital means; 41.3% regularly carry out teleconsultations, only 6.1% through specific digital health platforms, 29.1% through non-specific platforms, by telephone 21.9% and by email (asynchronous) 10.9%. The main perceived barriers were: availability, financial remuneration, regulations, connectivity problems and lack of time. Conclusion : The perception of professionals is fa vorable, as they considered these technologies useful to improve therapeutic adherence, which could have a facilitating effect on their implementation, although the perceived barriers are part of organizational issues to be resolved.

RESUMEN: La importancia y relevancia de los cursos e-learning en medicina y ciencias de la salud ha aumentado significativamente en la última década. A pesar de ello, existen pocas experiencias docentes publicadas de cursos de histología e-learning en la literatura a nivel mundial. El curso de histología que diseñamos se estructuró en la plataforma Moodle, y los contenidos se propusieron en formato síncrono (zoom) y asíncrono (grabaciones). También incluimos el uso de herramientas gratuitas de microscopía virtual. Este estudio tuvo como objetivo investigar el impacto de un curso de histología e-learning en la satisfacción y el rendimiento de los estudiantes de medicina, enfermería y obstetricia. La muestra incluyó 424 estudiantes chilenos de medicina, enfermería y obstetricia de dos cohortes. Se aplicó una encuesta tipo Likert al final del curso. Se realizó un análisis exploratorio y una regresión por mínimos cuadrados ordinarios. En este estudio, presentamos una experiencia positiva de un curso de e-learning de histología. El análisis factorial exploratorio reveló tres factores principales relacionados con la "satisfacción sobre el aprendizaje e-learning", "clases presenciales versus clases virtuales" y el "diseño del curso y la calidad de la enseñanza". También encontramos que existía una relación positiva y significativa entre las percepciones de los estudiantes sobre la adaptación del curso de histología tradicional (presencial) a un formato e-learning y su rendimiento académico. Nuestro estudio muestra que los cursos de histología e-learning que integran clases teóricas y sesiones prácticas pueden ser una valiosa herramienta de enseñanza. Los responsables de la elaboración de planes de estudios y los profesores de histología deben tener en cuenta las limitaciones y ventajas de este tipo de enseñanza y sugerimos incorporar estos tres factores al diseño y la evaluación de los cursos de histología en línea.

SUMMARY: The importance and relevance of e-learning courses in medicine and health sciences has increased significantly in the last decade. Despite this, there are few published teaching experiences of e-learning histology courses in the literature worldwide. The histology course we designed was structured on the Moodle platform as a learning management system, and the content was proposed in a synchronous (zoom) and asynchronous (recordings) format. We also included the use of free virtual microscopy tools. This study aimed to investigate the impact of an e-learning histology course on the satisfaction and performance of medical, nursing and midwifery students. The sample included 424 Chilean medical, nursing, and midwifery students from two cohorts. A Likert-type survey was administered at the end of the course. We performed exploratory analysis and ordinary least squares regression. In this study, we present a positive experience of an e-learning histology course. Exploratory factor analysis revealed three main factors related to "e- learning satisfaction", "in-person class activities", and "course design and teaching quality". We also found that there was a positive and significant relationship between students' perceptions of the adaptation of the traditional (face-to-face) histology course into an e-learning format and their academic performance. Our study shows that e-learning histology courses that integrate lectures and practical sessions can be a valuable teaching method for learning histology. Curriculum developers and teachers need to consider the limitations and advantages of this type of teaching and incorporate these three factors into the design and assessment of e-learning histology courses.

Durante la pandemia de COVID-19, las instituciones de educación superior tuvieron que adoptar un formato de aprendizaje diferente al de las clases presenciales. Una de las alternativas fue la llamada Enseñanza Remota de Emergencia (ERL), que transformó la enseñanza presencial tradicional en instrucción remota sincrónica. Este estudio tiene como objetivo obtener información sobre las mejores prácticas de aprendizaje en línea a partir de una encuesta en la que estudiantes de una universidad brasileña respondieron periódicamente a una pregunta abierta sobre su experiencia con ERL durante un período determinado. Los datos se recopilaron en diferentes momentos durante el primer año de la pandemia y abarcaron más de 19.000 respuestas. Las respuestas de los estudiantes a la pregunta abierta se analizaron utilizando el marco de las Comunidades Académicas de Compromiso (ACE). El análisis de las percepciones sobre el período de ERL permitió reflexionar sobre aspectos relevantes del compromiso emocional, cognitivo y conductual de los estudiantes, con posibles aplicaciones en contextos de enseñanza en línea sincrónicos o asincrónicos. Los estudiantes asociaron el aprendizaje remoto con modalidades en línea, expresando agotamiento y dificultades para manejar los estudios, el trabajo y la familia. Los comentarios negativos sobre la tecnología, la metodología y los instructores afectaron las dimensiones cognitivas, emocionales y conductuales. Los datos subrayan que las actividades sincrónicas en línea requieren tecnología accesible, estrategias específicas y métodos que fomenten la colaboración para generar compromiso. Este artículo proporciona contribución significativa sobre la implementación de la enseñanza remota dirigida al aprendizaje y la satisfacción de los estudiantes.

During the COVID-19 pandemic, higher education institutions needed to adopt a different learning format from in-person classes. One of the alternatives was the so-called Emergency Remote Learning (ERL), transforming traditional in-person teaching into synchronous remote instruction. This study aims to gain insights into online learning best practices based on a Brazilian university survey in which students periodically responded to an open-ended question about their experience with ERL over a determined period. Data was collected at different times during the first year of the pandemic and encompassed more than 19,000 responses. Students' responses to the open-ended question were analyzed using the Academic Communities of Engagement (ACE) framework. Analyzing student perceptions of the ERL period allowed for reflection on relevant aspects of students' emotional, cognitive, and behavioral engagement, with potential applications in synchronous or asynchronous online teaching contexts. Students associated remote learning with online modalities, expressing exhaustion and difficulties managing studies, work, and family. Negative comments regarding technology, methodology, and instructors affected cognitive, emotional, and behavioral dimensions. The data underscores that online synchronous activities necessitate accessible technology, specific strategies, and methods that foster collaboration to build engagement. This article gives insights for implementing remote teaching experiences aimed at student learning and satisfaction.

Uma das alternativas foi o chamado Ensino Remoto Emergencial (ERL), transformando o ensino presencial tradicional em ensino remoto síncrono. Este estudo tem como objetivo obter informações sobre as melhores práticas de aprendizagem online com base nas respostas de estudantes de uma universidade brasileira a uma pergunta aberta, aplicada periodicamente em uma pesquisa online, sobre sua experiência com o ERL durante o primeiro ano da pandemia. Os dados foram coletados em diferentes momentos do ano, tendo sido coletadas mais de 19.000 respostas. As respostas à pergunta aberta foram analisadas usando a estrutura das Comunidades Acadêmicas de Engajamento (ACE). A análise das percepções dos estudantes sobre o período de ERL permitiu realizar uma reflexão sobre aspectos relevantes do envolvimento emocional, cognitivo e comportamental dos alunos, com potenciais aplicações em contextos de ensino online síncronos ou assíncronos. Os estudantes associaram o ensino remoto às modalidades online, expressando exaustão e dificuldades de gestão de estudos, trabalho e família. Comentários negativos sobre tecnologia, metodologia e professores afetaram as dimensões cognitiva, emocional e comportamental. Os dados ressaltam que as atividades síncronas online exigem tecnologia acessível, estratégias específicas e métodos que promovam a colaboração para criar engajamento. Este artigo fornece contribuições sobre estratégias para a implementação de experiências de ensino remoto que objetivem o aprendizado e a satisfação dos estudantes.

The study is aimed at better understanding responsiveness of contact universities to technology-assisted education Post-Covid-19 pandemic. The suggestion is that a strong relationship exists between positive technology application in teaching and disciplines acceptance of technology. Without disciplines acceptance of technology, its application in teaching poses a challenge. When compelled, force majeure, to rely on technology to save an academic year, contact universities showed resilience. Students' laptops were hastily organised and synchronous online learning ensued. The application of technology in a particular context and this way is called a factor set 1. Two such factors appear in literature as the first factor set which entails synchronous technology-as-utility factor set 1 (FS-1) and asynchronous technology-as-essence factor set 2 (FS-2). There was, however, a need to develop a framework to better understand how technology is applied within the education context. Furthermore, we employed Peer Conversational Interviews with five teachers with less than five years of teaching experience and those possessing more than fifteen years teaching experience. These data were supplemented with data drawn from exploratory descriptive analysis of literature. These data collection efforts were intended to find out whether contact universities applied technology using FS-1 or FS-2 and implications of such decisions in reimagining contact universities beyond Covid-19 pandemic. Results show a strong relationship between disciplines such as IT and Engineering and the positive application of technology in terms of FS-2. They also show that post-pandemic, students are gradually warming to online teaching offerings. There is a need to provide more support to disciplines that show a lackadaisical attitude towards technology application in their areas.

This article presents the findings of a South African study conducted in a private Higher Education Institution. The aim of the article was to explore teaching strategies suitable for hybrid classrooms, to create an environment to integrate virtual and in-person student groups for optimal learning outcomes. A hybrid classroom requires academic staff to engage both groups in student-centred activities and therefore, this article argues that traditional teaching strategies may not be optimal in achieving integration. This exploratory study employed a practical action research design, to teaching strategies in hybrid classrooms. The data was collected by conducting class observation and two focus groups. The study used Braun and Clarke's (2006) thematic analysis for data analysis. The findings indicated that academic staff have a limited understanding regarding teaching strategies that would bridge the gap between virtual and in-person students. The study emphasised the necessity of an inquiry-based mindset in the hybrid teaching environment. The focus groups unanimously advocated for adopting an "adapted student-centred instructional approach" to address hybrid classroom challenges. This research contributes to understanding student-centred teaching strategies in hybrid classrooms. The key insight was that teacher-centred approaches by academic staff did not equally integrate virtual and in-person student participation. The study underscores the importance of lecturer training in effective student-centred teaching strategies for optimal learning in hybrid classrooms

ABSTRACT Introduction: Scientific and technological developments require continuous nurses' updating. This update would be achieved through continuous training and lifelong learning, which face some obstacles such as the need for reconciliation with personal and family life. The use of massive, online and asynchronous courses allows nurses access to current and targeted content to their needs, enhancing autonomy and learning management. With this study, we aim to assess the ease of use, perceived utility and intention for using a Massive Open Online Course (MOOC) in continuous nursing training. Methodology: Observational, exploratory and descriptive study using a non-probabilistic convenience sample. The study took place in the Department of Internal Medicine of a Central Hospital in the North of Portugal. Results: 141 nurses participated in this study. The results showed high perceived user-friendliness and utility of the learning program, and the nurses' intention for using a MOOC in the future. Discussion: The perceived usefulness, ease and intention are supported by the perceived quality in the contents, by the adequacy to perceived needs, using active pedagogical strategies such as the integration of virtual clinical simulation, and the perceived accessibility to training content. Conclusion: The use of a MOOC, made available from Information and Communication Technologies, has a high potential for acceptance and use in continuing nursing training, contributing not only to the safety and quality of care, but also for an adequate management of nurses' personal and professional lives.

Recomendaciones claves incluyen, brindar información completa y oportuna a pacientes, conformación de equipos multidisciplinarios, análisis individualizado del paciente para la decisión de tratamiento, estadificación rutinaria de riesgo dinámico para evaluar la respuesta al tratamiento y ajustarlo, minimización de procedimientos fútiles o que aportan poco a la supervivencia y calidad de vida de los pacientes. Conclusión: Se presentan recomendaciones que esperan incidir en la estandarización de la práctica clínica cotidiana de pacientes con CDT y mejores resultados en salud.

ABSTRACT Introduction: Thyroid cancer is a common disease in the world, with a higher prevalence of the differentiated type. Early diagnosis individualized and adaptive management can improve prognosis. Objective: Generate evidence-based recommendations on the treatment and follow-up of adults with differentiated thyroid carcinoma (DTC). Methodology: Clinical practice guideline (CPG) based on systematic literature review (RSL) and consensus of clinical experts. The development group defined the range and four questions that were resolved through a review of evidence from existing CPGs, RSLs, primary studies published in Spanish or English in various sources of information since 2013. The research questions were: 1. What are the indications for active surveillance? How to carry it out? When and how often to carry it out? 2. What is the treatment and its indication in patients with thyroid nodules suspicious for cancer? 3. How and when to follow up patients with CDT according to dynamic risk? 4. What is the current management of iodine refractory patients? Evidence-based recommendations analyzed and discussed by the expert group in asynchronous sessions were proposed. The quality of the evidence was evaluated, and the recommendations were graded as strong or conditional and in favor or against based on the analysis of the quality of the evidence, implementation context (availability and implementation) and clinical expertise. In this document, is developed the first question, referring to active surveillance. Results: 86 recommendations were proposed and agreed upon by the development group, categorized into treatment and follow-up to solve the questions raised. 10 of the recommendations correspond to active surveillance and are included in this document. Key recommendations include providing complete and timely information to patients, develop of multidisciplinary teams, individualized patient analysis for treatment decisions, routine dynamic risk staging to evaluate response to treatment and adjust it, minimization of futile procedures or that contribute little to the survival and quality of life of patients. Conclusion: Recommendations are presented that longs to influence the standardization of the daily clinical practice of patients with DTC and better health outcomes.

ABSTRACT As a result of the 2020 pandemic, an unexpected change occurred in university teaching, which mobilized higher education institutions to make a change in the way in-person teaching was conceived and consequently mobilized institutions towards a new educational paradigm, moving from face-to-face models to hybrid teaching and learning models with synchronous and asynchronous classes. This study aims to describe and analyze the impact of the implementation of evaluation strategies based on the empowerment and active participation of students. The methodology addressed complies with a qualitative approach with case studies. The results obtained show that the commitment of the students, from an evaluation process, which required them to make decisions, has a positive impact showing their expectations of academic achievement. Therefore, it is concluded that the possibility of generating and agreeing with the evaluation students in accordance with the learning results formally established in the program and the syllabus, promoting social justice at the time of evaluation, having each and every possibility to achieve the expected learning, it mobilized them towards a collective commitment among their peers, as well as the confidence of achieving the expected performances. The possibility of going beyond traditional tests, giving space to the generation of other products or evidence that confirms the achievement of learning implied placing students at the center of their own learning.

Visible light communication is a present technology which allows data to be transmitted by modulating information onto a light source. It has many advantages over traditional radio frequency communication and up to 10,000 times larger bandwidth. Many existing research in visible light communication assumes a synchronized channel, however, this is not always easily achieved. This paper proposes a novel synchronized VLC system with the potential to ensure reliable communication in both intra- and inter-vehicle communication. The protocol achieves synchronization at the symbol level using the transistor-transistor logic protocol and achieves frame synchronizations with markers. Consequently, the deployment of the system in both intra- and inter-vehicle communication may present numerous advantages over existing data transmission processes. A practical application where visible light communication is used for media streaming is also previewed. In addition, various regions of possible data transmission are determined to infer forward error correction schemes to ensure reliable communication.

ABSTRACT Objective. Chagas disease poses a public health problem in Latin America, and the electrocardiogram is a crucial tool in the diagnosis and monitoring of this pathology. In this context, the aim of this study was to quantify the change in the ability to detect electrocardiographic patterns among healthcare professionals after completing a virtual course. Materials and Methods. An asynchronous virtual course with seven pre-recorded classes was conducted. Participants answered the same questionnaire at the beginning and end of the training. Based on these responses, pre and post-test results for each participant were compared. Results. The study included 1656 participants from 21 countries; 87.9% were physicians, 5.2% nurses, 4.1% technicians, and 2.8% medical students. Initially, 3.1% answered at least 50% of the pre-test questions correctly, a proportion that increased to 50.4% after the course (p=0.001). Regardless of their baseline characteristics, 82.1% of course attendees improved their answers after completing the course. Conclusions. The implementation of an asynchronous online course on electrocardiography in Chagas disease enhanced the skills of both medical and non-medical personnel to recognize this condition.

Resumo Neste estudo, avaliamos a variação nos eventos fenológicos vegetativos e reprodutivos de quatro espécies de plantas filogeneticamente relacionadas submetidas a um ambiente sazonal. Para isso, amostramos 15 indivíduos de cada espécie quinzenalmente, pelo período de um ano, entre janeiro e dezembro de 2017. Para avaliar quando uma determinada fenofase ocorreu de modo mais intenso na população foi utilizado o índice de intensidade de Fournier e a sincronia dos indivíduos da amostra em determinado evento fenológico foi estimada utilizando-se o índice de atividade. O teste de Rayleigh (Z) foi usado para determinar se os eventos fenológicos têm distribuição sazonal. A relação dos fatores abióticos (fotoperíodo, precipitação, temperatura e umidade relativa) com a intensidade das fenofases foi avaliada para cada espécie de planta usando modelos lineares generalizados (GLMs). As fenofases de todas as plantas apresentaram um padrão de distribuição sazonal, bem como variação na sincronia das fenofases e conjuntos específicos de fatores abióticos influenciaram significativamente suas fenofases. Folhas novas, por exemplo, foram produzidas ao longo das estações, com intensa queda de folhas na estação seca. Os períodos de floração, por outro lado, não se sobrepuseram. De fato, as espécies exibiram floração sequencial e floração assíncrona entre os indivíduos. Nossos resultados sugerem que os padrões fenológicos das quatro espécies de plantas simpátricas estão diretamente ligados às variáveis climáticas, mas diferentes fatores abióticos afetaram diferentes fenofases.

Abstract In this study, we evaluated variation in vegetative and reproductive phenological events of four phylogenetically related plant species subjected to a seasonal environment. To this aim, we sampled 15 individuals of each plant species every fortnight for one year, between January and December of 2017. To assess when a given phenophase occurred more intensely in the population, the Fournier intensity index was used and the synchrony of individuals of the sample in a given phenological event was estimated using the activity index. The Rayleigh (Z) test was used to determine whether the phenological events have seasonal distribution. The relationship of abiotic factors (photoperiod, precipitation, relative humidity and temperature) with the intensity of phenophases was evaluated for each plant species using generalized linear models (GLMs). The phenophases of all plants showed a seasonal distribution pattern, as well as variation in synchrony of phenophases and specific sets of abiotic factors significantly influenced their phenophases. New leaves, for example, were produced throughout the seasons, with intense leaf fall in the dry season. Flowering periods, on the other hand, did not overlap. Indeed, species exhibited sequential flowering and asynchronous flowering among individuals. Our results suggest that the phenological patterns of four sympatric plant species are directly linked to climatic variables, but different abiotic factors affected different phenophases.

Abstract The objective of this article is to analyze the contributions of the Study of Classroom for the reinforcement of the theory/practice relation in the initial formation of teachers during the construction of concepts about exploratory tasks. For this, we collected data in two Lesson Studies remotely, through synchronous and asynchronous participation, carried out in two Supervised Internship II classes in the Degree in Mathematics, with twenty-eight future teachers and two teacher trainers. The results show that the Classroom Study favored the understanding of the exploratory tasks from the analysis of the curriculum and the elaboration and/or adaptation of tasks, thus alternating between theory and practice. We conclude that the Classroom Study carried out during the internship revealed the difficulties of future teachers in preparing or adapting exploratory tasks, justified by the lack of experience with this type of activity, as they did not know other types of tasks in addition to exercises and problems, which highlighted the need for theoretical and practical study of tasks and their contributions to initial training. theorypractice practice remotely participation Mathematics twentyeight twenty eight trainers andor activity problems training

Resumo O objetivo deste artigo é analisar as contribuições do Estudo de Aula para o reforço da relação teoria/prática na formação inicial de professores durante a construção de conceitos sobre tarefas exploratórias. Para isso, coletamos dados em dois Estudos de Aula, de modo remoto, através da participação síncrona e assíncrona, realizados em duas turmas de Estágio Supervisionado II, na Licenciatura em Matemática, de vinte e oito futuros professores e duas professoras formadoras. Os resultados mostram que o Estudo de Aula favoreceu a compreensão das tarefas exploratórias a partir da análise do currículo e da elaboração e/ou adaptação de tarefas, alternando assim entre teoria e prática.

Abstract The description of secretory structures in Malvaceae is controversial, and results in conflicting interpretations. Amid conflicting interpretations, therefore, the present study aims to describe the ontogeny diversity and histochemistry in Ceiba, emphasizing the secretory structures in leaves of C. erianthos, C. jasminodora, C. pentandra, and C. speciosa. All analyzed species present mucilaginous, crystalliferous, and phenolic idioblasts. These structures are randomly arranged in the mesophyll, epidermis, petiole cortex, and parenchymatic tissue of the midrib. However, in C. jasminodora and C. pentandra, secretory structures are only found in the midrib area. The development of mucilaginous idioblasts is asynchronous and, when mature, they coalesce forming large structures full of mucilage. Clavate-type pluricellular glandular trichomes were also detected scattered randomly on both leaf surfaces. Their ontogeny is described, and histochemical tests showed the presence of lipophilic substances. Extrafloral nectaries were observed in the middle third of the midrib, on the abaxial side of the leaflets. They originate from the protoderm and ground meristem of the midrib cortex. It is expected that these results will help consolidate knowledge of secretory structures in Malvaceae, leading, in turn, to the elucidation of phylogenetic relationships. controversial interpretations therefore Ceiba C erianthos pentandra speciosa crystalliferous mesophyll epidermis cortex However area mature mucilage Clavatetype Clavate type surfaces described substances leaflets leading turn relationships

Resumo A descrição das estruturas secretoras em Malvaceae não é consenso e resulta em interpretações conflitantes. Em meio a interpretações conflitantes, o presente estudo tem como objetivo descrever a diversidade ontogenética e histoquímica em Ceiba, enfatizando as estruturas secretoras em folhas de C. erianthos, C. jasminodora, C. pentandra e C. speciosa. Todas as espécies analisadas apresentam idioblastos mucilaginosos, cristalíferos e fenólicos. Tais estruturas estão dispostas aleatoriamente no mesofilo, epiderme, córtex do pecíolo e no tecido parenquimático da nervura central. Porém, em C. jasminodora e C. pentandra, encontram-se apenas na região da nervura central. O desenvolvimento de idioblastos mucilaginosos é assíncrono e quando maduros, coalescem formando grandes estruturas repletas de mucilagem. Tricomas glandulares pluricelulares do tipo clavado também foram detectados distribuídos aleatoriamente em ambas as superfícies foliares. Sua ontogenia é descrita e testes histoquímicos evidenciaram a presença de substâncias lipofílicas. Nectários extraflorais foram observados no terço médio da nervura central, na face abaxial dos folíolos. Estes se originam da protoderme e do meristema fundamental do córtex da nervura central. Espera-se que estes resultados ajudem a consolidar o conhecimento das estruturas secretoras em Malvaceae, levando, por sua vez, à elucidação das relações filogenéticas. conflitantes Ceiba C erianthos speciosa fenólicos mesofilo epiderme central Porém encontramse encontram maduros mucilagem foliares lipofílicas folíolos Esperase Espera levando vez filogenéticas

Abstract: Aim This study evaluates the reproduction and fecundity of Leporinus lacustris in upper Paraná River floodplain environments with the objectives to (i) recognize the germ cells of folliculogenesis and oogenesis; (ii) characterize reproductive phases; (iii) investigate oocyte diameter and evaluate if this species has group synchronous or asynchronous oocyte development and if spawning is total or batch; (iv) estimate batch fecundity; (v) establish the relationship between fecundity/ovary weight, standard length, and total weight; (vi) verify the reproductive areas of this species in the upper Paraná River floodplain. Methods Sampling was carried out using gillnets in rivers, and open and closed lagoons, in March, June, September, and December 2013, 2014, 2015, 2016, 2018, and 2019 and March and September 2017. A total of 442 females were sampled and 111 subsampled, each of which had an ovary removed and fixed in Bouin solution. A subsample of 20 ovaries in the spawning capable phase were fixed in a 4% buffered formaldehyde solution to estimate the diameter of the oocytes and fecundity. The ovaries were dehydrated, embedded in historesin, cut, stained, and evaluated as regards folliculogenesis, oogenesis, development phases, and reproduction areas. Results The germ cells recorded were differentiated oogonia, primary and secondary growth oocytes, fully-grown and mature oocytes, and post-ovulatory follicles that permitted the recognition of the reproductive phases. Oocyte diameter information revealed that the species has group synchronous oocyte development, determinate fecundity and batch spawning, and eliminates an average of 38,490 oocytes. Conclusions The fact that Leporinus lacustris is reproductively successful in the Baía River and in the Fechada, Guaraná, Patos, Garças, Ventura and Ressaco do Pau Véio lagoons strengthens the importance of the areas of environmental protection of the islands and lowlands of the Paraná River, Ilha Grande National Park and Ivinheima River State Park.

Resumo: Objetivo Este estudo avaliou a reprodução e fecundidade de L. lacustris em ambientes da planície de inundação do alto rio Paraná, com os objetivos de: (i) reconhecer as células germinativas da foliculogênese e oogênese; (ii) caracterizar as fases reprodutivas; (iii) investigar o diâmetro dos oócitos e avaliar se esta espécie tem o desenvolvimento dos oócitos sincrônico em grupo ou assincrônico e se a desova é total ou parcelada; (iv) estimar a fecundidade do lote; (v) estabelecer a relação entre fecundidade/peso do ovário, comprimento padrão e peso total e (vi) verificar as principais áreas de reprodução desta espécie na planície de inundação do alto rio Paraná. Métodos As amostragens foram realizadas em rios, lagoas abertas e fechadas no alto rio Paraná, com redes de espera nos meses de março, junho, setembro e dezembro de 2013, 2014, 2015, 2016, 2018 e 2019 e março e setembro de 2017. Foram amostradas 442 fêmeas e subamostradas 111, das quais foi retirada uma subamostra do ovário e fixada em solução de Bouin. Uma subamostra de 20 ovários na fase apta a desova foi fixada em solução de formaldeído tamponado a 4%, para posteriormente, estimar o diâmetro dos oócitos e fecundidade. Resultados As células germinativas registradas foram: oogônias diferenciadas, oócitos de crescimento primário e secundário, oócitos de crescimento completo e maduros, e folículos pós-ovulatórios que permitiram reconhecer as fases reprodutivas. As informações do diâmetro dos oócitos revelou que a espécie tem desenvolvimento dos oócitos sincrônico em grupo, fecundidade determinada e desova parcial, e elimina no período de desova em média 38.490 oócitos. Conclusões Leporinus lacustris reprodutivamente bem sucedido no rio Baía e nas lagoas Fechada, do Guaraná, dos Patos, das Garças, do Ventura e do Ressaco do Pau Véio reforçando a importância das áreas de proteção ambiental das ilhas e várzeas do rio Paraná, Parque Nacional da Ilha Grande e Parque Estadual do rio Ivinheima.
