Distinct Neuromodulatory Effects of Endogenous Orexin and Dynorphin Corelease on Projection-Defined Ventral Tegmental Dopamine Neurons
Authors: Mohammadkhani Aida , Qiao Min , Borgland Stephanie L.
Published: August 2024

Dopamine (DA) neurons in the ventral tegmental area (VTA) respond to motivationally relevant cues, and circuit-specific signaling drives different aspects of motivated behavior. Orexin (ox; also known as hypocretin) and dynorphin (dyn) are coexpressed lateral hypothalamic (LH) neuropeptides that project to the VTA. These peptides have opposing effects on the firing activity of VTADAneurons via orexin 1 (Ox1R) or kappa opioid (KOR) receptors. Given that Ox1R activation increases VTADAfiring, and KOR decreases firing, it is unclear how the coreleased peptides contribute to the net activity of DA neurons. We tested if optical stimulation of LHox/dynneuromodulates VTADAneuronal activity via peptide release and if the effects of optically driven LHox/dynrelease segregate based on VTADAprojection targets including the basolateral amygdala (BLA) or the lateral or medial shell of the nucleus accumbens (lAcbSh, mAchSh). Using a combination of circuit tracing, optogenetics, and patch-clamp electrophysiology in male and female orexincremice, we showed a diverse response of LHox/dynoptical stimulation on VTADAneuronal firing, which is not mediated by fast transmitter release and is blocked by antagonists to KOR and Ox1R signaling. Additionally, where optical stimulation of LHox/dyninputs in the VTA inhibited firing of the majority of BLA-projecting VTADAneurons, optical stimulation of LHox/dyninputs in the VTA bidirectionally affects firing of either lAcbSh- or mAchSh-projecting VTADAneurons. These findings indicate that LHox/dyncorelease may influence the output of the VTA by balancing ensembles of neurons within each population which contribute to different aspects of reward seeking.

Published: August 2024

Objetivo: analisar a evidência científica sobre a influência do suporte social na adesão ao regime terapêutico por pessoas que vivem com HIV/aids. Métodos: revisão integrativa realizada nas bases de dados CINAHL, MEDLINE, Web of Science e SCOPUS, com base no acrônimo PICo, sendo P: pessoa vivendo com HIV/aids; I: suporte social; C: adesão ao regime terapêutico. Resultados: obtiveram-se 364 artigos e 19 foram selecionados. Evidenciaram que a ausência de suporte social por parte dos profissionais de saúde, particularmente do enfermeiro, da família/pessoa significativa, vizinhos, amigos e comunidade resulta na diminuição ou não adesão ao regime terapêutico. Conclusão: as pessoas que vivem com HIV/aids e têm percepção do suporte social e da sua efetividade, apresentam menos sintomas depressivos e comportamentos de risco, e maior adesão ao regime terapêutico. Contribuições para a prática: contribui para que os profissionais de saúde, em especial os enfermeiros que prestam cuidados a pessoas com HIV/aids, reconheçam a relevância de aprofundar o conhecimento sobre as redes de suporte social, de modo a envolvê-las no planejamento de cuidados para melhor adesão ao regime terapêutico e enriquecimento da saúde mental.

Authors: Li Qihang , Li Kai , Yuan Canming
Published: August 2024

To solve the global environmental problem of a shortage of freshwater resources, seawater desalination is considered one of the most promising solutions. In this research, the main novelty of the seawater desalination system lies in its utilization of a reverse osmosis unit as the core process for producing drinking water. By optimizing the pretreatment section in the process flow, a seawater reverse osmosis (SWRO) control system based on Siemens PLC with a high degree of automation was developed, which has the advantages of convenient maintenance and monitoring. In addition, through research on reverse osmosis systems, the results showed that within two years of operation, the total desalination rates of the primary and secondary reverse osmosis systems were not less than 99% and 97.5%, respectively. Furthermore, the water quality after desalination was tested. When the doses of CaCl2, MgCl2 and NaHCO3 were 20 mg/L, 15 mg/L, and 50 mg/L, respectively, high-quality drinking water was obtained. Finally, a reasonable process plan and corresponding estimates were given for the complex water source conditions. Compared with traditional seawater desalination systems, our system has the advantages of easy operation, efficient water production and lower price. Accordingly, this study will help to solve drinking-water problems in some freshwater-scarce regions.

Published: August 2024

Levas Vladimirovas, born on February 27, 1912, is an outstanding authority in the field of modern Soviet library science, as well as the history of books and libraries.
The essential part of Levas Vladimirovas' life and his entire scientific and teaching career is closely linked with Vilnius University. After World War II, he lectured on Marxism-Leninism (1948), the history of the book, and library science (1951). He was the first head of the Department of Library Science (1952-1964) and later the Department of Library and Information Science (1970-1973). Since 1973, Levas Vladimirovas has been the head of the Department of Information Science. Additionally, between the years 1948-1964, he served as the director of the university library.
Between 1964-1970, Levas Vladimirovas was elected director of the UNO Dag Hammarskjöld Library. His contribution to the development of the library is immense. Levas Vladimirovas was also a member of various international library organizations and institutions.
Alongside his many-sided teaching, library, and social activities, Levas Vladimirovas has made significant contributions to science. More than 300 publications in Lithuanian, Russian, English, and other languages are attributed to his pen. The focus of Levas Vladimirovas' research lies in the history of Lithuanian books, libraries, and culture during the feudal and capitalist periods. He was the first to investigate both known and new phenomena in the Lithuanian cultural heritage through the lens of Marxist methodology.
Among his most outstanding works are Essays on the History of the Book and Libraries in Lithuania (XV cent. to 1917) ("Lietuvos bibliotekų ir knygos istorijos bruožai (XV a.-1917 m.)", 1965); publications dedicated to the pioneers of book printing in Vilnius—F. Skorina and I. Fedorov; and works on the history of Vilnius University and its library. L. Vladimirovas' comprehensive work The History of the Book ("Knygos istorija", 1979) provides a broad panorama of world book history, starting with primitive scripts up to the 17th century.
In 1962, for his teaching, scientific, and social activities, Levas Vladimirovas was awarded the title of Honored Art Worker of the Lithuanian SSR. The professor was also among those who were awarded the Lithuanian State Prize for The History of Vilnius University ("Vilniaus universiteto istorija") in three volumes.

Training of information retrieval in the State university of Vilnius: some contential and technological aspects of education in the field of librarianship and bibliography
Authors: Prokopčik Marija
Published: August 2024

The article deals with the problem of professional education of librarians at the University of Vilnius. The changing role of information, which is becoming one of the natural resources of the country, and the rapid development of computer technology reveal new professional demands for librarians. As a result of this tendency, teaching online bibliographical searching has become of great importance in the library education curriculum.
Specific conditions of development and practical needs of libraries and information services, main traits, and opportunities of higher education in Lithuania are revealed. This makes it possible to create an original conception of automated information retrieval training. The problems of information retrieval are studied in subjects such as Librarianship, Bibliography, Information Retrieval Systems, Information, and Technical Aids for Library Work, which are based on a specially created training automated information retrieval system (AIRS).
Three different kinds of connections between the revealed subjects are presented in a scheme and commented upon.
The choice of education technology is discussed. The main forms are various practical studies, realized on the basis of AIRS. These also help overcome the psychological barrier that arises when working with computers.
A methodology of informatics: the role of methodology in improvement of theory
Authors: Voverienė Ona
Published: August 2024

The article has a propounding character. Based on methodological literature, the essence of the concept "methodology" is revealed, explaining the role of scientific methods in knowledge and the role of methodology in improving theory and research work in some fields of knowledge. The results of the literature analysis are considered a starting point for investigating the methodology of informatics.
Currently, there is no developed system of philosophical, scientific, and general-theoretical principles that determine the program and methods for investigating the theory and methodology of informatics. Additionally, there is no established theory of method and scientific approach to the objective evaluation of practice. The absence of methodology is a major cause and effect of the crisis in contemporary information theory.
We can only discuss the methods used in research work in the field of informatics. Special methods in informatics—such as statistical analysis of scientific documents, statistical analysis of references, and the method of ranking—are characterized. The main laws of informatics are discovered using these methods. A definition of the methodology of informatics and its main aims is put forward for discussion.

Published: August 2024

ABSTRACT Objectives: to investigate the influence of the leukoreduction moment (preor post-storage) of blood components on the clinical outcomes of patients transfused in the emergency department. Methods: retrospective cohort study of patients aged 18 years or older who received preor post-storage leukoreduced red blood cell or platelet concentrate in the emergency department and remained in the institution for more than 24 hours. A generalized mixed-effects model was applied in the analyses. Results: in a sample of 373 patients (63.27% male, mean age 54.83) and 643 transfusions (69.98% red blood cell), it was identified that the leukoreduction moment influenced the length of hospital stay (p<0.009), but was not dependent on the transfused blood component (p=0.124). The leukoreduction moment had no effect (p>0.050) on transfusion reactions, healthcare-associated infections, or mortality. Conclusions: patients who received pre-storage leukoreduced blood components in the emergency department had a shorter length of hospital stay.
Pensar lo humano desde transepistemes en la decolonialidad planetaria-complejidad

Published: August 2024

Resumen: Los epistemes de los seres humanos entran en crisis con la práctica de estos. Dejan en evidencia su incapacidad de haberse conocido; en tanto su complejidad expedita es: naturaleza-cuerpo-mente-alma-espíritu-Dios. Como objetivo de investigación sustentamos transepistemes para pensar los seres humanos en la decolonialidad planetaria-complejidad. El prefijo trans hereda concepciones del legado de Enrique Dussel. Investigamos en medio de transmetodologías maravillosas, en las líneas de investigaciones tituladas: decolonialidad planetaria-complejidad en re-ligaje; transmetodologías complejas y los transmétodos decoloniales planetarios-complejos. Con el transmétodo la deconstrucción rizomática conseguimos transepistemes como: los seres humanos son creación de Dios, transepisteme raíz de todos; el espíritu deviene del soplo de vida de la creación dada por Dios al barro en Adán; el ser humano es político, gregario y él puede reformar su pensamiento. La demencia, la maldad, falta de solidaridad no forman parte de la creación, sino deviene del pecado; que se incita en el humanismo, transhumanismo y el ataque a la naturaleza de la creación con el apoyo de la inteligencia artificial.
ENSINO ENCANTADO DE CIÊNCIAS: APORTES DECOLONIAIS DAS MACUMBAS E ENCRUZILHADAS
Authors: REBELLO THIAGO JOSÉ JESUS , LIMA ROGERIO MENDES DE , MEIRELLES ROSANE MOREIRA SILVA DE
Published: August 2024

RESUMO: O conceito de colonialidade repercute a presença dos padrões racistas de poder do colonialismo na realidade contemporânea. Tendo por base a Epistemologia das Macumbas e a Pedagogia das Encruzilhadas - pensadas por Luiz Rufino e Luiz Antônio Simas -, propomos o ensino encantado de ciências: uma possibilidade de transgressão da colonialidade por meio do ensino de ciências. Primeiro, posicionamos a obra de Simas e Rufino dentro do pensamento decolonial. Em seguida, discutimos os fundamentos da Epistemologia das Macumbas e da Pedagogia das Encruzilhadas, com destaque para os conceitos de encantamento e cruzo. Como conclusão, propomos o ensino encantado de ciências como projeto pautado na crítica à ocidentalidade e na construção da interculturalidade a partir das macumbas brasileiras.
PÚBLICO-PRIVADO NO FINANCIAMENTO DA EDUCAÇÃO ESPECIAL: QUEM GANHA E QUEM PERDE NO MERCADO DA BENEMERÊNCIA?
Authors: NUNES LORRANA OLIVEIRA , RODRIGUES ANA CLÁUDIA DA SILVA
Published: August 2024

RESUMO: Este artigo objetiva analisar o jogo de disputas e negociações pelo fundo público entre as parcerias público-privadas no financiamento da educação especial. As discussões derivam da revisão bibliográfica e documental de escritos alinhados ao objetivo eleito e estão sustentadas nos pressupostos teóricos do materialismo histórico-dialético (MARX, 1985). Na análise das fontes consultadas, verificou-se que, no contexto de desoneração do Estado, em relação às políticas sociais, as parcerias público-privadas ganham a disputa no mercado da benemerência, em detrimento ao público-alvo da educação especial, e buscam os recursos do fundo público e a participação nos direcionamentos das políticas educacionais. Evidenciou-se, ainda, que a parceria entre o Estado e o setor privado contribuiu para precarizar o ensino público, alimentar tensões entre os direitos conquistados e os direitos efetivados e descumprir as metas do PNE 2014-2024 e dos pactos firmados entre o Brasil e os organismos internacionais, como a Declaração de Salamanca (1994). Por outro lado, os achados revelaram algumas saídas para combater o apartheid social e educacional, que tem sido disseminado pela classe empresária na saga da disputa pelo fundo público: desenvolver a capacidade de organização, de acesso à informação e de comunicação interna para garantir os investimentos públicos; superar a gestão centralizada nos espaços escolares e fortalecer o controle social por meio da participação social e popular.
EXPANSÃO E MERCANTILIZAÇÃO DOS CURSOS DE PEDAGOGIA: DEFORMAÇÃO EM LARGA ESCALA DE FUTUROS PEDAGOGOS

Published: August 2024

RESUMO: Este artigo traz a análise das características da expansão dos cursos de Pedagogia no Brasil, especialmente na última década, com base em dados do Censo da Educação Superior e do Exame Nacional do Desempenho do Estudante (Enade), do Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep), atualizados até 2021. O processo de expansão do curso de Pedagogia segue duas tendências: em nível macro, tem-se o processo de crescimento da educação privada de nível superior, especialmente concentrada em poucos grupos financeirizados; em nível micro, tem-se um conjunto de induções legais para que a formação de professores ocorra em nível superior e a consolidação do curso de Pedagogia como lugar privilegiado da formação de professores para a Educação Infantil e os anos iniciais do Ensino Fundamental em oposição a outros cursos como o Normal Superior. Os resultados apresentados por este trabalho apontam para o que foi aqui denominado como “deformação em larga escala”, considerando a crescente concentração das matrículas em universidades privadas centradas quase que exclusivamente no ensino (com pouca articulação com pesquisa e extensão), em cursos a distância, com altas taxas de evasão e baixas notas no Enade na comparação com instituições públicas federais e estaduais.
THE NEAR ABSENCE OF THE NATIONAL CURRICULUM GUIDELINES IN THE NATIONAL COMMON CURRICULUM BASE
Authors: MOREIRA ANA SANTANA , SILVA EMERSON PIRES DA , SOUZA WÁRICA SANTOS , ECHEVERRÍA AGUSTINA ROSA
Published: August 2024

ABSTRACT: This article analyzes the near absence of the National Curriculum Guidelines for Basic Education (in Portuguese, DCN) in the Common National Curriculum Framework (BNCC in Portuguese). We conducted a documentary study with a critical approach to the curricular debates anchored in the Historical-Critical Pedagogy theoretical-methodological foundations. The aim is to analyze and reflect on the educational guidelines for groups underrepresented in curricular educational policies to debate the formation processes of the subjects. The categories of analysis were: 1) modalities of education (Indigenous School; Quilombola School; Rural; Special; Youth and Adult; Vocational and Technological Schools); and 2) contemporary thematic axes (Environmental education; Human Rights Education; Education for young people and adults deprived of liberty in penal institutions; Education of Ethnic-Racial Relations and the Teaching of Afro-Brazilian and African History and Culture; School assistance for children, adolescents and young people in itinerant situations). The results indicate a silencing and a setback in the BNCC, concerning some modalities and thematic axes that had their rights guaranteed in the DCN. On the other hand, in the BNCC, though presenting the principles of equality and universality, the subjects are homogenized, disregarding the differences and subjectivities that exist or may exist. We advocate for an education that effectively considers Brazilian society's diversity and profound inequalities, seeking an omnilateral formation of subjects from a social transformation perspective.
SEX EDUCATION IN THE DIFFERENT VERSIONS OF THE COMMON NATIONAL CURRICULUM FRAMEWORK: FROM OPENING TO SILENCING AROUND THE THEME
Authors: VICENTE LUCIANE DA SILVA
Published: August 2024

ABSTRACT: This study aims to analyze how sex education is inserted in the different versions of the National Common Curricular Framework (BNCC) and present teachers' perceptions about the context of narratives and disputes that intermediated its construction. This qualitative study used BNCC as a data source and semi-structured interviews with eight elementary-school teachers. We produced data using the Discourse Analysis technique, guided by the policy cycle formulated by Stephen Ball and Richard Bowe, whose procedures demonstrated that the incisive action of conservative political groups culminated in regressive policies in the field of sexuality, failing to show important dimensions in the final document. We understand that the omission of these issues in the curricular references favors the persistence of intolerance against sexual diversity and weakens the fight against prejudice and discrimination rooted in our society.
THE USE OF INFORMATION AND COMMUNICATION TECHNOLOGIES IN HIGHER EDUCATION DURING COVID-19 PANDEMIC

Published: August 2024

ABSTRACT: The pandemic caused by the new coronavirus has brought several challenges to higher education and education in general. The nationwide lockdown disrupted traditional face-to-face teaching and forced teachers and students to stay home. The closure of all educational institutions led to the need to think about alternatives to continue the teaching-learning process. Thus, the educational field has experienced significant variation in terms of including a range of information and communication technologies (ICTs) tools. This qualitative and exploratory research starts from a universe of 283 online journalistic articles from the first two years of the pandemic that, after selection, resulted in 27 articles for a more detailed analysis. The results converge to three major areas: (1) structural aspects, (2) those concerning the teaching staff, and (3) those on the students. The analysis of the selected materials verified that, as support tools, the ICTs gave the educational system more flexibility, adaptability, and dynamism, allowing the continuity of the teaching process. Though these technologies have brought new and significant possibilities for educational practices, they have faced, and still face, several challenges related to teacher training, educational teams' resistance to changes, educational institutions' structural characteristics, and the need for students' motivation.
OS SABERES DOCENTES NA ÁREA DE ENSINO DE CIÊNCIAS: UMA REVISÃO SISTEMÁTICA

Published: August 2024

RESUMO: Neste trabalho realizamos uma revisão sistemática da literatura com os intuitos de compreender como os saberes docentes têm sido investigados na área de Ensino de Ciências no Brasil e de discutir as principais contribuições e limitações dessas investigações. Realizamos nossas buscas no Banco de Teses e Dissertações da CAPES e no Portal de Periódicos da CAPES, a partir de um recorte temático, mas não temporal. Com base nos critérios de inclusão e exclusão definidos, obtivemos um total de 64 trabalhos (teses, dissertações e artigos). Por meio desses trabalhos, identificamos e caracterizamos cinco eixos de investigação: saberes mobilizados por professores de Ciências; saberes docentes e a identidade profissional; processos de construção e desenvolvimento dos saberes docentes; contribuições de cursos e programas de formação na constituição dos saberes docentes; outros focos. Observamos que prevalecem as pesquisas que buscam apenas identificar os saberes docentes sob uma perspectiva individual de análise ao priorizarem, principalmente, métodos de categorização e análise de conteúdo. Limitações como essa apontam para a necessidade de que um esforço seja realizado no sentido de ampliar o escopo das investigações sobre a temática de forma a incluir e considerar, sob uma perspectiva etnográfica, a análise desses saberes docentes como fenômeno social, que se constrói na interação do professor com seus alunos, com seus pares e demais membros da comunidade educacional.
TEACHING KNOWLEDGE IN THE AREA OF SCIENCE EDUCATION: A SYSTEMATIC REVIEW

Published: August 2024

ABSTRACT: In this work, we carried out a systematic review of literature aiming to understand how teaching knowledge has been investigated in the area of Science Teaching in Brazil and to discuss the main contributions and limitations of these investigations. We’ve done our research on the Bank of Thesis and Dissertations of CAPES and on the Portal for Periodicals of CAPES, using a thematic, but not temporal, approach. Based on the defined criteria of inclusion and exclusion we’ve obtained a total of 64 works (theses, dissertations, and articles). Through these works we’ve identified and characterized five axes of investigation: knowledge mobilized by teachers of Science; teaching knowledge and the professional identity; processes of construction and development of the teaching knowledge; contributions of courses and formation programs on the constitution of teaching knowledge; other focuses. We’ve observed that the researches that seek only to identify the teaching knowledge under an individual analysis perspective are the ones which prevail, especially methods of categorization and content analysis. Limitations such as that point out the need for an effort to amplify the scope of the investigations on the thematic of form and to include and consider, under an ethnographical perspective, the analysis of theses teaching knowledge as a social phenomenon, which is constructed on the interaction between teacher and student, with his peers and the other members of the educational community.

ABSTRACT: This study was conducted with the aim of analyzing the implications of removing the parameters from the mathematical model on the results of path analysis, with oats grown in different years and agricultural scenarios (with and without fungicide). For this, two field trials were conducted in southern Brazil, in five years of growth. The experimental design used in trial I (with fungicide application) was randomized complete blocks (RCB), in a 22 × 4 bifactorial arrangement, characterized by twenty-two oat cultivars and four fungicide applications. For trial II (without fungicide application) the RCB design was used, and the treatments were characterized by twenty-two oat cultivars, with three replications. The traits measured were panicle length, panicle mass, number of spikelets, number of grains, grain mass, and grain yield. For each year, data group, and scenario, the correlation coefficients between the explanatory variables and grain yield were calculated. The diagnosis of multicollinearity indicated violation of the statistical assumption, so it was necessary to proceed with a path analysis under multicollinearity (ridge). The removal of parameters from the mathematical model caused changes in the linear relationships between the oat yield traits, with the maintenance of the linear correlation coefficients in 3.30% and 20% of the situations, for the scenarios with and without fungicide application, respectively. Regarding the path coefficients, it was observed that the direct effects were maintained in 3.30% and 30% and indirect effects in 7.33% and 24.67% of the situations, for the scenarios with and without fungicide application, respectively.

ABSTRACT: In traditional sheep production systems in tropical regions, the evaluation and monitoring of animal growth are not commonly practiced. This is primarily attributed to the limited adoption of technology and the high costs associated with acquiring livestock scales. The present study developed equations to predict body weight of Pelibuey ewe lambs using a Body Volume (BV) formula. BW and BV were obtained from 85 ewe lambs. The models evaluated were as follows: 1) linear, 2) quadratic, 3) cubic, 4) allometric, 5) exponential and 6) logarithmic. In addition, the models’ predictive ability for BW was assessed by k-fold (k=10) cross-validation. The BW and BV were 20.60 ± 8.73 kg and 17.54 ± 7.89 dm3, respectively. The quadratic model showed the highest r2 and the lowest values of mean square error, root mean square error, and bayesian information criterion, while the k-fold cross-validation technique also had the highest r2 and the lowest values of mean squared prediction error and mean absolute error. The quadratic model was the best performing mathematical model for predicting BW of growing Pelibuey ewe lambs using BV.

ABSTRACT Peach palm (Bactris gasipaes) is a native tree from Brazil widely used for obtaining palm heart. Due to the increasing interest in palm heart, plantations are expanding to the Brazilian South and Southeast regions. Peach palm processing generates high amounts of solid wastes, which are inadequately disposed of and have no consolidated use. Proposing potential utilizations for the valorization of these lignocellulosic matrices requires knowing their chemical composition. This work aimed to determine the chemical composition (at mineral, nutritional, and macromolecular levels) of the three by-products (internal sheath, external sheath, and basal portion) generated during the processing of the peach palm, to characterize their semi-volatile compounds, and to compare them to the edible palm heart. The by-products represent 83.6% (w/w) of the biomass in the peach palm processing and have a high dietary fiber content (59.2 - 68.1%). Internal sheath and basal portion showed high protein content (8.40 - 11.8%) according to Brazilian legislation and several bioactive compounds such as myo-inositol and organic acids (succinic, gallic, and linoleic acids), indicating their nutraceutical properties and potential to be used as food additives or ingredients in food formulation. Besides, the external sheath had high cellulose content (39.6%) that could be extracted and applied in material science. All by-products have compounds of interest to the industry and a high potential to be employed in the development of products with higher added value.

ABSTRACT Wild lettuce (Lactuca aff. canadensis L.), belonging to the Asteraceae family, occurs subspontaneously in Brazil and may originate from Africa, Asia, Europe and North America. Popularly known as Canada lettuce, it is an unconventional leafy vegetable. Studies on this species are scarce in Brazil, and its scientific name is debated among experts. It has high morphological variability and controversial botanical classification. This study characterized the stomata, organized the karyotype, and determined the nuclear DNA content of four morphotypes of wild lettuce to facilitate correct classification. The genetic material used was acquired from the non-conventional vegetable germplasm in UFLA. The leaves of wild lettuce morphotypes are hypoamphiestomatic with a greater number of stomata in the abaxial epidermis. There were similarities between the morphotypes (green and purple) and between the smooth purple types (narrow leaf and broad leaf) for the number and size of stomata. No variation was found in the number of chromosomes (2n = 18) or DNA content among the four morphotypes. The separation of the morphotypes of wild lettuce did not match the morphological classification or the karyological data. The four morphotypes evaluated were placed under the same species, and the results obtained when compared to other studies led us to infer that the four morphotypes of wild Lactuca belonged to the species L. indica and not L. canadensis as previously assumed. Further investigation may provide insights into the evolutionary history of this species.

ABSTRACT Kale is one of the most widely cultivated leafy vegetables in Brazil, but its breeding genetic is still limited. Therefore, it is crucial to develop research that explores the genetic diversity of the available germplasms, aiming to establish promising crosses in the studied populations. The present study aimed to evaluate the genetic divergence between half-sibling progenies of kale, obtained through recurrent selection, using multivariate methods to select the most promising progenies for forming a recombinant population. The plants obtained from the seeds of 25 pre-selected half-sibling progenies and three commercial cultivars were evaluated as treatment groups. These seeds were produced in 2018 by subjecting the clones of the progenies to recombination, followed by the selection of appropriate seeds from plants with superior agronomic performance. In the present study, plants in each plot were evaluated for twelve quantitative and fifteen qualitative traits. Genetic divergence was studied based on canonical variables to obtain quantitative data. The UPGMA method was applied to the quantitative, qualitative, and combined data, and Mahalanobis genetic distance was adopted. The first three canonical variables explained 73.75% of the total cumulative variation compared to the commercial cultivars and 55.29% when considering the half-sibling progenies exclusively. The half-sibling progenies P1, P2, P3, P4, P5, P9, P11, P15, P16, P18, P20, P22, P23, P24, and P25 were the most divergent and should, therefore, be prioritized when composing the recombinant population for the third cycle of recurrent selection because, in addition to genetic variation, these progenies also present characteristics of interest to the kale genetic breeding program. The commercial cultivars exhibited the most divergent genotypes and should, therefore, be included in the next recombination cycle.

Abstract In this study, we analyzed associations between vaccination knowledge, vaccination intention, political ideology, and belief in conspiracy theories before and during the 2020 Sars-Cov-2 pandemic in the Brazilian population. It was conducted a longitudinal study into three data collections. Participants responded to the Flexible Inventory of Conspiracy Suspicions (FICS), questionnaires measuring their knowledge, and opinion about vaccines, and sociodemographic data. The results were: the greater the belief in conspiracy theories about vaccines, the lesser the intention to get vaccinated, the vaccine knowledge, and the attitudes towards vaccine investment. Religious, prone to right-wing politics, parents, and older people scored more for FICS than atheists/agnostics, and younger people. From 2019 to 2020 the vaccination intention and vaccination investment did not differ, showing that people did not change their opinion about vaccines regardless of personal experience or the pandemic scenario. The research strengthened the relevance of health education as a milestone for public health and protection from dangerous conspiracy theories.

Abstract Public Health Consortiums (PHC) in Brazil represent a strategy to enhance regionalization in the Public Health Care System (SUS in Portuguese) and State/interstate/intermunicipal cooperation. The establishment of regional polyclinics aims to improve access to services with greater technological concentration and closer to users’ homes. This study specifically aims to analyze the process of creating PHC and regional polyclinics in Bahia State, based on documental analysis, identifying aspects related to entering the political agenda that facilitate and hinder, the role of state administration, specificities of the composition of these PHC and regional polyclinics. A documental analysis was carried out of the minutes of the Comissão Intergestores Bipartite (CIB-BA) [Bipartite Administrative Commission] from 2015 to 2018 and of constitutive documents of the consortiums established in this state. The Ceará State experience inspired the creation of consortiums in Bahia, especially the structuring of polyclinics. Municipal administrators demonstrated a favorable position regarding the potential of consortiums with cooperation among municipalities. The role of the state government proved to be a facilitating condition, whereas the maintenance of the municipal counterpart in finance constituted a hindering element. The consortiums contributed to the regionalization of health in the state as well as expansion of access to specialized care.

Resumo O objetivo foi analisar a distribuição espacial da gravidez em menores de 14 anos e seis meses segundo regiões e municípios brasileiros e características sociodemográficas e de saúde das parturientes e nascidos vivos. Estudo ecológico, analisando o Sistema de Informação sobre Nascidos Vivos (SINASC), 2011-2021, em três grupos etários (<14 anos e 6 meses, 15-19 e 20 anos e mais), segundo variáveis demográficas e do parto. Foram aplicados os Índices Global e Local de Moran. No período foram 127.022 nascidos vivos de meninas 10-14 anos, na maioria negras, 21,1% em união estável ou casadas, com menor proporção de 7 consultas de pré-natal e captação no primeiro trimestre, maior proporção de baixo peso ao nascer e baixo índice de Apgar, residentes nas regiões Norte e Nordeste. A taxa média de nascidos vivos de 10-14 anos mostrou autocorrelação significativa com o espaço, especialmente em municípios do Centro-Oeste e Norte. A gravidez de 10 a 14 revela uma sequência de vulnerabilidades sofridas por essas meninas, pela gravidez em idade precoce, maior frequência entre negras, com implicações na morbimortalidade para ela e seus filhos; e pela violência presumida nesses casos, incluindo o acesso negado ao aborto legal.
