Published: July 2023

The rod photoreceptor synapse is the first synapse of dim-light vision and one of the most complex in the mammalian CNS. The components of its unique structure, a presynaptic ribbon and a single synaptic invagination enclosing several postsynaptic processes, have been identified, but disagreements about their organization remain. Here, we have used EM tomography to generate high-resolution images of 3-D volumes of the rod synapse from the female domestic cat. We have resolved the synaptic ribbon as a single structure, with a single arciform density, indicating the presence of one long site of transmitter release. The organization of the postsynaptic processes, which has been difficult to resolve with past methods, appears as a tetrad arrangement of two horizontal cell and two rod bipolar cell processes. Retinal detachment severely disrupts this organization. After 7 d, EM tomography reveals withdrawal of rod bipolar dendrites from most spherules; fragmentation of synaptic ribbons, which lose their tight association with the presynaptic membrane; and loss of the highly branched telodendria of the horizontal cell axon terminals. After detachment, the hilus, the opening through which postsynaptic processes enter the invagination, enlarges, exposing the normally sequestered environment within the invagination to the extracellular space of the outer plexiform layer. Our use of EM tomography provides the most accurate description to date of the complex rod synapse and details changes it undergoes during outer segment degeneration. These changes would be expected to disrupt the flow of information in the rod pathway.

SIGNIFICANCE STATEMENTRibbon-type synapses transmit the first electrical signals of vision and hearing. Despite their crucial role in sensory physiology, the three-dimensional ultrastructure of these synapses, especially the complex organization of the rod photoreceptor synapse, is not well understood. We used EM tomography to obtain 3-D imaging at nanoscale resolution to help resolve the organization of rod synapses in normal and detached retinas. This approach has enabled us to show that in the normal retina a single ribbon and arciform density oppose a tetrad of postsynaptic processes. In addition, it enabled us to provide a 3-D perspective of the ultrastructural changes that occur in response to retinal detachment.

Held on December 9 and 10, 2021, the meeting was organized by the Quillca program, which is devoted to the study of South American colonial art and housed in the Centro de Estudios sobre Arte, Materia y Cultura of Argentina’s Tres de Febrero University. The Congress, whose opening and closing lectures were given by Ilona Katzew (Los Angeles County Museum of Art) and Felipe Pereda (Harvard University), was an opportunity to study the provocative (that is, “bad”) side of Ibero-American images. The dictionary of the Royal Spanish Academy defines malo (bad) as that which has “valor negativo, falto de las cualidades que cabe atribuirle por su naturaleza, función o destino” (negative value, lacking the qualities that ought to be attributed to it, given its nature, function or purpose).

Cells use noncanonical autophagy, also called conjugation of ATG8 to single membranes (CASM), to label damaged intracellular compartments with ubiquitin‐like ATG8 family proteins in order to signal danger caused by pathogens or toxic compounds. CASM relies on E3 complexes to sense membrane damage, but so far, only the mechanism to activate ATG16L1‐containing E3 complexes, associated with proton gradient loss, has been described. Here, we show that TECPR1‐containing E3 complexes are key mediators of CASM in cells treated with a variety of pharmacological drugs, including clinically relevant nanoparticles, transfection reagents, antihistamines, lysosomotropic compounds, and detergents. Interestingly, TECPR1 retains E3 activity when ATG16L1 CASM activity is obstructed by the Salmonella Typhimurium pathogenicity factor SopF. Mechanistically, TECPR1 is recruited by damage‐induced sphingomyelin (SM) exposure using two DysF domains, resulting in its activation and ATG8 lipidation. In vitro assays using purified human TECPR1‐ATG5‐ATG12 complex show direct activation of its E3 activity by SM, whereas SM has no effect on ATG16L1‐ATG5‐ATG12. We conclude that TECPR1 is a key activator of CASM downstream of SM exposure.
Preferencje w wyborze metod gromadzenia i analizy danych studentów kierunków pedagogicznych – refleksja na przykładzie studentów Uniwersytetu Łódzkiego

Published: July 2023

Methodological preferences play an important role in managing the research process (Szmatka, Lovaglia & Mazur, 1996) and may also significantly determine the substantive choices of the researcher (Van de Walle, 2017). In the context of reports on the low methodological awareness of pedagogy students and the occurrence of secondary methodological illiteracy among them (Duraj-Nowakowa, 1993), it was considered important to address the issue of methodological preferences of students of pedagogy. This article presents the preliminary results of the study of female pedagogy students regarding their methodological preferences. Significant aspects of shaping methodological preferences were indicated and the necessity to consider the education of pedagogical students in the area of data analysis methods was noticed. Moreover, the difficulties of students in acquiring knowledge and skills in the field of research methodology were emphasized. Considerations regarding methodological preferences should be continued, as they are an expression of concern for the improvement of the effectiveness of teaching in the field of methodological subjects, which in turn contributes to the optimization of the process of educating pedagogues (ibidem).

Published: July 2023

This study aims to analyze the level of industrial agglomeration using balassa index and spatial analysis. In addition, this study also analyzes the effect of industrial agglomeration, investment, infrastructure, and inequality on economic growth. The data used in this study are secondary data. This study uses panel data regression with a fixed effect model approach, consisting of 34 provinces in Indonesia for the period 2015-2020. The results of this study indicate that industrial agglomeration occurs in 7 provinces in Indonesia (Kepulauan Riau, West Java, Central Java, DI Yogyakarta, East Java, Banten, and Bali) with an average balassa index value of 1.34 and included in low levels. Industrial agglomeration tends to occur on Java Island. The results of the regression analysis in this study indicate that industrial agglomeration, investment, and infrastructure have a positive effect on economic growth in Indonesia, while inequality has a negative effect on economic growth in Indonesia.

Published: July 2023

Nineteen cases of parathyroid carcinoma in patients with multiple endocrine neoplasia type 1 have been reported in the literature, of which 11 carry an inactivating germline mutation in the MEN1 gene. Somatic genetic abnormalities in these parathyroid carcinomas have never been detected. In this paper, we aimed to describe the clinical and molecular characterization of a parathyroid carcinoma identified in a patient with MEN1. A 60-year-old man was diagnosed with primary hyperparathyroidism during the postoperative period of lung carcinoid surgery. Serum calcium and parathyroid hormone levels were 15.0 mg/dL (8.4–10.2) and 472 pg/mL (12–65), respectively. The patient underwent parathyroid surgery, and histological findings were consistent with parathyroid carcinoma. Analysis of the MEN1 gene by next-generation sequencing (NGS) identified a novel germline heterozygous nonsense pathogenic variant (c.978C>A; p.(Tyr326*)), predicted to encode a truncated protein. Genetic analysis of the parathyroid carcinoma revealed a c.307del, p.(Leu103Cysfs*16) frameshift truncating somatic MEN1 variant in the MEN1 gene, which is consistent with MEN1 tumor-suppressor role, confirming its involvement in parathyroid carcinoma etiology. Genetic analysis of CDC73, GCM2, TP53, RB1, AKT1, MTOR, PIK3CA and CCND1 genes in the parathyroid carcinoma DNA did not detect any somatic mutations. To our knowledge, this is the first report of a PC case presenting both germline (first-hit) and somatic (second-hit) inactivation of the MEN1 gene.

Primary aldosteronism (PA) is associated with urolithiasis as it causes hypercalciuria and hypocitraturia. However, the influence of different subtypes of PA on urinary stone formation remains unclear. This study aimed to evaluate the association between aldosterone-producing adenoma (APA) and the burden of urolithiasis in patients with PA. In the present study, we enrolled 312 patients with PA from a prospectively maintained database, of whom 179 had APA. Clinical, biochemical, and imaging data (including the presence, volume, and density of urinary stones on abdominal computed tomography) were compared between groups, with employment of propensity score matching (PSM) analysis to balance possible confounding factors. Kaplan–Meier analysis was used to estimate the acute renal colic event during follow-up. After PSM for age, sex, serum calcium, phosphate, blood urea nitrogen, creatinine, and uric acid, the APA and non-APA groups had 106 patients each. Patients with APA had higher serum intact parathyroid hormone (iPTH) (79.1 ± 45.0 vs 56.1 ± 30.3, P < 0.001) and a higher prevalence of urolithiasis (27.4% vs 12.3%, P = 0.006) than non-APA patients. During follow-up, a higher incidence of acute renal colic events was noted in the APA group than the non-APA group (P = 0.011); this association remained significant (P = 0.038) after adjustment for age and sex in Cox-regression analysis. Our data suggest that APA is associated with a heavier burden of urolithiasis and higher incidence of renal colic events compared to the non-APA subtype of PA.
Decreased programmed cell death ligand 2-positive monocytic myeloid-derived suppressor cells and programmed cell death protein 1-positive T-regulatory cells in patients with type 2 diabetes: implications for immunopathogenesis
Authors: Liu Zhaoxiang , Zhang Mingqiang , Shi Xiaohu , Zhao Wenhui , Cao Chenxiang , Jin Lixia , Wang Yanlei , Xiao Jianzhong
Published: July 2023

Objectives

The activation of immune cells plays a significant role in the progression of type 2 diabetes. This study aimed to investigate the potential role of myeloid-derived suppressor cells (MDSCs) and T-regulatory cells (Tregs) in type 2 diabetes.

Methods

A total of 61 patients diagnosed with type 2 diabetes were recruited. Clinical characteristics were reviewed and peripheral blood samples were collected. We calculated the percentage of different cells. Frequencies of MDSC subsets refered to the percentage of G-MDSCs (CD15+CD33+CD11b+CD14-HLA-DR-/low) in CD45 positive cells and the percentage of M-MDSCs (CD14+CD15-CD11b+CD33+HLA-DR-/low) in lymphocytes plus monocytes.

Results

Frequencies of programmed cell death ligand 1-positive granulocytic MDSCs (PD-L1+ G-MDSCs), programmed cell death ligand 2-positive monocytic MDSCs (PD-L2+ M-MDSCs), PD-L2+ G-MDSC, and programmed cell death protein 1-positive Tregs (PD-1+Tregs) were decreased in patients with type 2 diabetes. The frequency of PD-1+ Tregs was positively related to PD-L2+ M-MDSCs (r= 0.357, P = 0.009) and negatively related to HbA1c (r = -0.265, P = 0.042), fasting insulin level (r = −0.260, P = 0.047), and waist circumference (r = −0.373, P = 0.005).

Conclusions

Decreased PD-L2+ M-MDSCs and PD-1+ Tregs may promote effector T cell activation, leading to chronic low-grade inflammation in type 2 diabetes. These findings highlight the contribution of MDSCs and Tregs to the immunopathogenesis of type 2 diabetes and suggest their potential as targets for new therapeutic approaches.
Production of aromatic aldehyde by microwave catalytic oxidation of a lignin model compound with La-containing SBA-15/H2O2 systems
Authors: Gu Xiaoli , He Ming , Shi Yijun , Li Zhongzheng
Published: July 2023

A convenient and efficient application of heterogeneous La-containing SBA-15 systems for the microwave assisted oxidation of a lignin model phenolic monomer, 4-hydroxy-1-phenylpropane, is reported. Low-cost and environmentally friendly H2O2 was used as the oxygen atom donor. The catalyst was prepared by immobilizing lanthanum species on the periodic mesoporous channels of siliceous SBA-15. Powder X-ray diffraction data and ICP-AES revealed that the host retains its hexagonal mesoporous structure after immobilization and most of the lanthanum species are better dispersed in the calcined materials. The surface area and pore size of La/SBA-15 was considerably decreased, indicating the intrapore confinement of the Lanthanum species. The activity of the La/SBA-15 was investigated in the oxidation of 4-hydroxy-1-phenylpropane in the presence of hydrogen peroxide as oxidant. 70.5% conversion of 4-hydroxy-1-phenylpropane was obtained after 30 min of reaction under 200W microwave irradiation, compared to a poor 28.1% degradation after 24h under conventional heating. The possibility of recycling the catalyst was studied.
Characterization of key parameters for biotechnological lignocellulose conversion assessed by FT-NIR spectroscopy. Part 2. Quantitative analysis by partial least squares regression
Authors: Krongtaew Chularat , Messner Kurt , Ters Thomas , Fackler Karin
Published: July 2023

Wheat straw (Triticum aestivum L.) and oat straw (Avena sativa L.) were chemically pretreated at different severities with the purpose of delignification, which in turn leads to a better accessibility of plant cell wall polysaccharides for further biotechnological conversion. Key parameters of these samples, i.e. weight loss, residual lignin content, and hydrolysable sugars serving as precursors for biofuel production were monitored by wet-chemistry analyses. Fourier transform near infrared (FT-NIR) spectra were correlated to these data by means of partial least-squares (PLS) regression. Weight loss (4.0 – 33.5%) of the wheat straw could be predicted (RMSEP = 3.5%, R²test = 0.75) from the entire FT-NIR spectra (10000 – 4000 cm-1). Residual lignin content (7.9 – 20.7%, RMSEP = 0.9%, R²test = 0.94) and amount of reducing sugars based on pretreated wheat straw (128 – 1000 mg g-1, RMSEP = 83 mg g-1, R²test = 0.89) were powerfully evaluated between 6900 and 5510 cm-1, a spectral region where polysaccharides and lignin absorb. All these parameters could be equally predicted with even higher accuracy from pre-treated oat straw samples. Furthermore, some important parameters for anaerobic conversion of wheat straw to biogas – biogas production, total solids, and volatile solids content – could be estimated.
Effect of birch kraft pulp primary fines on bleaching and sheet properties
Authors: Asikainen Sari , Fuhrmann Agneta , Ranua Marjatta , Robertsén Leif
Published: July 2023

By removing the primary fines from an oxygen-delignified mill birch pulp, a fiber fraction was obtained having low metals content and no extractives. After DEDeD bleaching the fiber fraction had somewhat higher brightness and better brightness stability than the birch pulp containing the primary fines. The fines fraction was enriched with lignin, extractives, xylan, and metals. Bleaching the fines fraction in a QQP sequence did not affect the extractives, whereas a ZeQP sequence clearly reduced the extractives content. In a biorefinery concept, the fines fraction could be utilized as a source of xylan, fatty acids, sterols, and betulinol. Another possibility is to use the fines fraction unbleached or separately bleached as a bonding material in various fiber furnishes.

Published: July 2023

Mechanical properties of polyethylene (PE) composites were evaluated as a function of the addition of bacterial cellulose (BC). It was found that BC could improve the mechanical properties of the composites with or without the combination of traditional wood fiber. The improvements were affected by post-treatment. It was confirmed that BC had a significant influence on impact strength. The pellicle form of BC was able to achieve superior impact strength compared to the fluffy form of BC, but had similar effects on the tensile strength in comparison to the composites with fluffy BC.

Published: July 2023

The aim of this study was to investigate the effect of esterification via acetic or propionic anhydride on the surface roughness of eastern cottonwood. Eastern cottonwood (Populous deltoides) was esterified by using acetic or propionic anhydride without using any solvent or catalyst under different conditions. Two different weight percentage gains (WPGs) were obtained for each of the modifying chemicals. Three main surface roughness parameters, namely average roughness (Ra), mean peak to valley height (Rz) and maximum roughess (Rmax) were measured by a stylus method before and after esterification. The surface roughness was significantly increased due to the esterifications. The surface roughness of wood increased with increasing WPG.
New Deformity Outline on the Breast Radiation Therapy for diminishing Absorbed Dose Ratio
Authors: Khorshidi Abdollah , Ashoor Mansour
Published: July 2023

Breast cancer is one of the most common malignant diseases in women. After tumor mass surgery, radiation therapy is regularly taken into account the gold standard for the treatment. Kilo to Mega voltage photons have been suggested due to their characteristic depth dose build-up regime, reducing the dose to the breast skin to a fraction of the maximum dose exposure. During treatment, mean glandular dose is commonly used as a criterion for identifying radiation risks. Here, two outlines in cubic-rectangular (CR) and cylindrical- taper (CT) outlines were modelled together with corresponding assumptions using Monte-Carlo simulation and the recorded absorbed dose ratio (ADR) values were compared via defined a positron source by 511 keV energy. The results showed that the amounts of absorption and scattering cross-sections next to the ADR amount decreased as the height of the CR outline decreased. The average dose ratio amount in the CR outline was reduced by about 96% compared to that in the CT outline. By increasing the positron source distance from the nipple, the ADR amounts decreased for both outlines. The amount of accumulated dose ratio decreased harshly in the CR outline rather than in the CT outline. This study can be useful to examine breast tissue deformity in treatment planning.

Published: July 2023

OBJECTIVES

Bacterial musculoskeletal infections (MSKIs) are challenging to diagnose because of the clinical overlap with other conditions, including Lyme arthritis. We evaluated the performance of blood biomarkers for the diagnosis of MSKIs in Lyme disease–endemic regions.

METHODS

We conducted a secondary analysis of a prospective cohort study of children 1 to 21 years old with monoarthritis presenting to 1 of 8 Pedi Lyme Net emergency departments for evaluation of potential Lyme disease. Our primary outcome was an MSKI, which was defined as septic arthritis, osteomyelitis or pyomyositis. We compared the diagnostic accuracy of routinely available biomarkers (absolute neutrophil count, C-reactive protein, erythrocyte sedimentation rate, and procalcitonin) to white blood cells for the identification of an MSKI using the area under the receiver operating characteristic curve (AUC).

RESULTS

We identified 1423 children with monoarthritis, of which 82 (5.8%) had an MSKI, 405 (28.5%) Lyme arthritis, and 936 (65.8%) other inflammatory arthritis. When compared with white blood cell count (AUC, 0.63; 95% confidence interval [CI], 0.55–0.71), C-reactive protein (0.84; 95% CI, 0.80–0.89; P < .05), procalcitonin (0.82; 95% CI, 0.77–0.88; P < .05), and erythrocyte sedimentation rate (0.77; 95% CI, 0.71–0.82; P < .05) had higher AUCs, whereas absolute neutrophil count (0.67; 95% CI, 0.61–0.74; P < .11) had a similar AUC.

CONCLUSIONS

Commonly available biomarkers can assist in the initial approach to a potential MSKI in a child. However, no single biomarker has high enough accuracy to be used in isolation, especially in Lyme disease–endemic areas.

Published: July 2023

This online antiracist program for children as young as 3 and their parents/caregivers took place in June of 2020 early in the COVID-19 pandemic. Driven by a desire to build change in opposition to racism and unite families during a time of quarantine and isolation, the program fuses family literacy practices to create space for discussions surrounding race, racism, anti-racism and alliance. The model of the program uses children’s literature to make difficult topics accessible to young children, and provides literacy activities which are engaging, age appropriate, and adaptable to materials at hand, interests, abilities and attention spans of each child. This success of this program demonstrates the power of the model to engage with young children and issues of social justice.

Published: July 2023

O estudo objetiva analisar a educação em tempo integral como política indutora de educação integral. Desenvolveu-se por pesquisa bibliográfica e análise documental. O texto dialoga com os estudos teóricos de Arroyo (2015); Azevedo (1997); Cavaliere (2002); Coelho (2005; 2009); Duarte (2008; 2012); Gallo (2002); Maurício (2009); Parente (2021); Santos e Orso (2020); Saviani (2012; 2013; 2019), dentre outros que tratam sobre a temática. Além disso, as discussões foram pautadas pelos marcos legais, como a Constituição Federal (CF) de 1988 (BRASIL, 1988), a Lei de Diretrizes e Bases da Educação Nacional (LDBEN) n. 9.394/96 (BRASIL, 1996), o Plano Nacional de Educação 2014-2024 (BRASIL, 2014) e a Base Nacional Comum Curricular (BNCC). Os resultados demonstraram que no complexo campo de luta e de contradição da sociedade capitalista, movido por forças que expressam diferentes interesses de classe, para que a educação em tempo integral se viabilize como política indutora de educação integral precisa enfrentar desafios e condicionamentos relacionados ao currículo, tempo, espaço, profissionais da educação e financiamento, que demandam um Sistema Nacional de Educação. Ademais, é inegável a importância da escola como espaço de aprendizagem e formação humana e o entendimento que educação e política são práticas distintas, porém inseparáveis.

Published: July 2023

O presente artigo apresenta os resultados de uma pesquisa de abordagem qualitativa e de natureza aplicada, que empregou a pesquisa-ação para analisar a atuação do Conselho Escolar (CE) de uma escola da Rede Municipal de Educação de Santo André. Dentre outros propósitos, buscou identificar a articulação dos representantes do conselho de escola com os diferentes segmentos da escola. Os dados foram obtidos por meio da observação direta da diretora de escola, que é uma das pesquisadoras e de um Grupo Focal, e contou com a participação de 13 representantes do CE. Os resultados mostram que os membros do CE ainda não têm interlocuções efetivas com os seus pares, salvo o segmento dos professores, por terem momentos coletivos nas reuniões pedagógicas semanais. Além disso, ainda é necessário investir em intercâmbios, de modo que seja possível, além de compartilhar as decisões, coletar as contribuições dos professores e demais representantes do CE em prol da implementação da gestão escolar democrática que, na escola investigada, está em vias de consolidação. Isso tem sido possível face ao comprometimento da diretora com uma gestão escolar participativa e democrática. Contudo, ela ainda não consegue incorporar todas as contribuições e proposições do CE na organização e gestão da escola.
Jesuítas e crianças no Brasil: estado da arte nas produções historiográficas
Authors: Borges Felipe Augusto Fernandes , Borges Elenice Alves Dias
Published: July 2023

Como primeira educação formal a ser empreendida em larga escala no Brasil, a educação jesuíta manteve-se como principal agente formador em terras brasílicas por mais de 200 anos, sendo, assim, assunto relevante para a historiografia da educação e da infância brasileiras. O intento deste trabalho foi realizar uma revisão bibliográfica das produções versando sobre as atividades dos padres da Companhia de Jesus no Brasil, envolvendo o ensino e a catequese de crianças, no período de 1549 a 1759. O objetivo é levantar o atual estado da arte, compreender o que foi produzido nos últimos anos a este respeito e, assim, contribuir para delinear novos caminhos de pesquisa. Para tanto, foi realizada uma pesquisa nas bases de dados da Scielo, da Biblioteca Digital Brasileira de Teses e Dissertações, do Portal de Periódicos da Capes e, também, no buscador Google Acadêmico. Foram usadas palavras chave tais como “Companhia de Jesus e crianças”; “Companhia de Jesus e infância”; “Jesuítas e crianças”; “Jesuítas e infância”. O que trazemos neste texto é uma visão panorâmica das produções levantadas, apontando pontos principais ligados à temática estudada. Este trabalho, portanto, espera contribuir no sentido de balizar em que ponto estão as produções a respeito da Companhia de Jesus e sua ação para com as crianças no Brasil e, assim, apontar para novos campos e frentes de pesquisa que podem ser desenvolvidas.

Published: July 2023

O artigo apresenta reflexões acerca das potencialidades de materiais manipuláveis para o desenvolvimento da percepção geométrica na Educação Infantil. A abordagem metodológica se inscreve no campo da pesquisa qualitativa de caráter descritivo-analítica. Os resultados revelaram que há uma variedade e quantidades de materiais que permitem a exploração da criatividade dos professores no tocante a criação de aulas diversificadas e que é possível explorar a percepção geométrica das crianças enquanto direito garantido pela legislação vigente. Nessa perspectiva, portanto, podemos considerar que o trabalho com os materiais manipuláveis oferece às crianças possibilidades de aprender e realizar descobertas, com as suas observações e vivências cotidianas, aproveitando o conhecimento que ela adquiriu antes e dentro da escola.
A comunicação de crianças de pré escola em atividades que envolvem o espaço
Authors: Curi Edda , Fernandes Gisella Carrera
Published: July 2023

Este artigo decorre de uma dissertação de mestrado, que apresenta resultados sobre a competência de comunicação oral, nas aprendizagens de alunos da Educação Infantil, Na Pré-Escola, com a faixa etária entre 5 e 5 anos e 11 meses, da EMEI Professora Cleide Moreira dos Santos, localizada num bairro da Zona Norte de São Paulo, sobre Relações Espaciais. A pesquisa busca investigar as relações das crianças nessa faixa etária com o Espaço Perceptivo e o Espaço Representativo à luz das pesquisas de Piaget e Inhelder (1993) e outros teóricos que estudam sobre o tema. Foram utilizados procedimentos de pesquisa qualitativa, como vídeo filmagens, observações e fotografias. Entre os resultados destacam-se o domínio gradativo do vocabulário espacial, passando do uso de um vocabulário genérico para um vocabulário específico. Mostram que a maioria das crianças desenvolvem a noção de lateralidade e outras estão a caminho. Revelam ainda que as crianças nessa faixa etária, ainda utilizam seu próprio corpo como referência na localização e movimentação de pessoas e objetos. No entanto, algumas delas já evidenciam a percepção de colocar-se na mesma posição do outro para poder indicar o sentido correto de um percurso ou a localização de um objeto.

Published: July 2023

RESUMEN:El siguiente estudio explora las emociones presentes en la resolución de los problemas del parto en los niños y en la educación infantil, sustentando el uso de la metáfora conceptual como herramienta que permite vislumbrar la construcción y comprensión de los aspectos importantes en el aula de matemáticas: 1 .los significados matemáticos, asociados a la división de objetos, y 2. las emociones de las matemáticas, que nacen de la experiencia de resolver problemas y se exponen a partir de expresiones y acciones desarrolladas por los niños. Este trabajo se enmarca en una metodología cualitativa de tipo fenomenológico consistente con una experiencia de 12 niños y niñas en el aula de matemáticas en la que, si son capaces de resolver los problemas de forma idónea y desarrollan nociones matemáticas correctas sobre la distribución, presentan un obstáculo afectivo en el proceso de aprehensión de este constructo matemático, para desencadenar actitudes, emociones y/o creencias inapropiadas en la solución de problemas por una mala experiencia; evidenciando, además, que el papel del docente es importante como guía de interacción para la reorientación de los mensajes que se presentan para la resolución de problemas en el aula.

Published: July 2023

Objetivo: Avaliar a ação, in vitro, do peróxido de hidrogênio nas concentrações de 1%, 1,5% e 3%, do cloreto de cetilpiridínio, do cloreto de benzalcônio de 1,3% e da clorexidina 0,12% associada ao peróxido de hidrogênio 1,5% sobre cepas padronizadas de microrganismos Enterococcus faecalis; Staphylococcus aureus; Candida albicans e Escherichia coli, aspirando determinar qual é o melhor produto. A clorexidina 0,12% foi utilizada como controle positivo e água destilada estéril como controle negativo. Material e metodos: Suspensões padronizadas dos microrganismos foram vertidas e espalhadas sobre o meio de cultura. Discos de papel estéril de 4 mm foram colocados no ágar semeado e embebidos com 15 microlitros (uL) de cada um dos antissépticos. As placas foram incubadas em estufa bacteriológica a 37º Celsius por 48 horas. Os resultados foram obtidos por meio do halo de inibição do crescimento. Resultado: O E. faecalis foi o microrganismo que apresentou maior resistência aos antissépticos testados, seguido por E. coli e pelo fungo C. albicans, já o S. aureus apresentou sensibilidade ao maior número de antissépticos. Conclusão: A clorexidina 0,12% associada ao peróxido de hidrogênio a 1,5% indicou uma possível ação sinérgica entre os produtos, aumentando a eficácia quando comparada ao uso isolado de cada um, o cloreto de benzalcônio 1,3% também apresentou ação antimicrobiana consideravel, porém antissépticos orais à base de clorexidina associada ao peróxido de hidrogênio e de cloreto de benzalcônio não estão disponíveis comercialmente, indicando que novos estudos possam ser feitos para o emprego destes produtos em soluções de antissepticos bucais.

Published: July 2023

Objetivo: O objetivo do presente estudo foi o de realizar uma Revisão de Literatura acerca dos cimentos reparadores disponíveis no mercado no que diz respeito à essas características esperadas. Metodologia: Foram utilizados artigos indexados nos bancos de dados LILACS, Scielo e PUBMED, nos anos de 1987 a 2017. Resultados: Os artigos da literatura relatam que cimentos reparadores como ProRoot MTA, MTA-Angelus, Endosequence Root Repair Material, Biodentine e Bioaggregate apresentam biocompatibilidade semelhante, oferecendo menor citotoxicidade quando comparados com outros cimentos disponíveis no mercado. A bioatividade desses cimentos baseia-se em induzir a diferenciação celular, inibir reabsorção óssea, liberar íons cálcio e favorecer a formação de depósitos de apatita, característica na qual mais uma vez os materiais apresentam resultados muito próximos. A maioria dos trabalhos confirmou a maior capacidade seladora de cimentos à base de MTA e silicato tricálcico, sendo o Biodentine o que apresentou os melhores resultados. Conclusão: Diante do exposto fica evidente a qualidade e similaridade dos materiais, cabendo ao cirurgião-dentista a opção pelo material com o qual melhor adaptar-se.

Compreende-se que o sistema carcerário de um modo geral, é palco para vários desafios, principalmente quando é citado mulheres em período gestacional. Objetivou-se analisar como a atuação da enfermagem seguindo dos seus cuidados no pré-natal pode influenciar na saúde dessa mulher e do seu bebê. Trata-se de uma revisão integrativa da literatura em bases de dados, com inclusão de artigos entre 2016 e 2021, na língua portuguesa, inglesa e espanhola. Foram encontrados 76 artigos e selecionados 21 que atendiam os critérios de inclusão. Considerando seus eixos temáticos, foram criadas três categorias: barreiras no serviço; percepção/atuação do profissional de saúde; e percepção das usuárias. Destaca-se a importância e a necessidade de uma equipe de enfermagem qualificada e apta para prestar uma assistência de qualidade, direcionada às mulheres que se encontram encarceradas e gestantes.
BRIDGING THE GAP: A SEQUENTIAL MIXED-METHODS STUDY OF TRUST NETWORKS IN GRADUATE APPLICATION, ADMISSIONS, AND ENROLLMENT
Authors: Villarreal Cynthia , Posselt Julie R. , Hernandez Theresa E. , Rudolph Alexander L.
Published: July 2023

Undergraduate education in the U.S. is racially/ethnically stratified, and there is limited mobility for
Black and Latinx BS recipients in STEM majors into the PhD programs from which faculty hiring disproportionately occurs. Bridge programs are proliferating as a means of increasing minoritized students' enrollment in STEM graduate programs, but little social science examines mechanisms of their impact or how impacts depend on the graduate programs to which students seek access. This sequential mixed-methods study of the Cal-Bridge program analyzed trust networks and mechanisms of relational trust as factors in graduate school application, admissions, and enrollment decisions. First, using social network analysis, we examined patterns in the graduate programs to which seven cohorts
of Cal-Bridge scholars applied, were admitted, and chose to enroll. Then, we conducted an in-depth
case study of the organization in the Cal-Bridge network with the highest centrality: University of California, Irvine's physics and astronomy PhD program. We find the positive admission and enrollment outcomes at UC Irvine were due to intentional, institutional change at multiple organizational levels. Change efforts complemented the activities of the Cal-Bridge program, creating conditions that cultivated lived experiences of mutual, relational trust between bridge scholars and their faculty advisors
and mentors. Findings illustrate mechanisms and antecedents of trust in the transition to graduate education. We use these findings to propose a framework that may inform the design of future research and practical efforts to account for the role of trust in inequities and creating more equitable cultures in STEM.
THE DOMESTIC VIOLENCE ACT 116 OF 1998: OFFENCES, DEFENCES, ECONOMIC ABUSE, IMMINENT HARM AND THE CRIME OF DOMESTIC ABUSE– WHAT IS NEW?
Authors: Sibisi Siyabonga
Published: July 2023

Recent tragedies relating to gender-based violence have drawn attention to the current state of our relevant law. This article focuses on domestic violence – a species of gender-based violence. It assesses the current state of the Domestic Violence Act 116 of 1998; in particular, it focuses on the offences and defences, as well as on the definition of economic abuse and the concept of imminent harm in relation to domestic abuse. The proposals to amend the definition of these concepts have culminated in the passing of the Domestic Violence Amendment Act 14 of 2021. The bulk of the amendments have not commenced. Nevertheless, this article also comments on the impact that these amendments will have on the thesis of this article. It also sheds some light on the proposed stand-alone crime of domestic abuse.

Published: July 2023

Objectives

Several Canadian provinces and territories have reformed their health systems by centralizing power, resources, and responsibilities. Our study explored motivating factors and perceived impacts of centralization reforms on public health systems and essential operations.

Methods

A multiple case study design was used to examine three Canadian provinces that have undergone, or are in the process of undergoing, health system reform. Semi-structured interviews were conducted with 58 participants within public health at strategic and operational levels, from Alberta, Ontario, and Québec. Data were analyzed using a thematic analytical approach to iteratively conceptualize and refine themes.

Results

Three major themes were developed to describe the context and impacts of health system centralization reforms on public health: (1) promising “value for money” and consolidating authority; (2) impacting intersectoral and community-level collaboration; and (3) deprioritizing public health operations and contributing to workforce precarity. Centralization highlighted concerns about the prioritization of healthcare sectors. Some core public health functions were reported to operate more efficiently, with less duplication of services, and improvements in program consistency and quality, particularly in Alberta. Reforms were also reported to have diverted funding and human resources away from core essential functions, and diminished the public health workforce.

Conclusion

Our study highlighted that stakeholder priorities and a limited understanding about public health systems influenced how reforms were implemented. Our findings support calls for modernized and inclusive governance, stable public health funding, and investment in the public health workforce, which may help inform future reforms.
