Published: January 2025

De que modo o trato docente com a consciência fonológica, explorada no contexto da “loa de maracatu”, pode colaborar para o aprendizado do sistema de escrita alfabética? Esse questionamento impulsiona este artigo, cujo objetivo é o de analisar estratégias didáticas direcionadas para o desenvolvimento da consciência fonológica, no âmbito do gênero textual “loa de maracatu”, vivenciadas no contexto da Educação de pessoas Jovens, Adultas e Idosas (EJAI) de uma escola da Rede Municipal localizada na Zona da Mata Norte de Pernambuco.  Aportadas nos estudos de Morais (2010; 2012; 2019) e Soares (2018), destaca-se, nas atividades analisadas, a identificação de palavras com as sílabas iniciais parecidas (aliteração); as semelhanças nas sílabas finais das palavras (rimas), assim como a relação entre a pauta sonora e a escrita. Os dados foram tratados sob um prisma qualitativo (Minayo, 2012), a partir de elementos da técnica de análise de conteúdo categorial (Bardin, 1977). O cenário revelou um trabalho significativo, o trato com a consciência fonológica, aos moldes abordados, oportunizou o envolvimento dos/as alunos/as com o gênero em questão, possibilitou atividades favoráveis a apropriação do sistema de escrita alfabética, ao mesmo tempo em que enalteceu a cultura de um grupo que milita por espaço e valorização.

Published: January 2025

O presente estudo, de natureza qualitativa e caráter teórico e documental, traz resultados parciais de pesquisa de doutorado realizada na Universidade Federal do Rio Grande do Norte. Partimos da premissa de que a problemática da alfabetização no Brasil é atual, pois está marcada por interesses políticos que envolvem a construção de um projeto de nação. Além disso, compreendida neste trabalho como um processo discursivo, a alfabetização engloba uma complexidade de fatores psicológicos, sociais, culturais, econômicos e metodológicos. O objetivo do presente artigo é discutir criticamente sobre a história da alfabetização no Brasil, com ênfase nos métodos de alfabetização e sua relação com algumas políticas públicas. Do ponto de vista teórico, o corpus de discussão e análise está fundamentado em Marcilio (2016) e Mortatti (2006). No que tange ao aspecto documental, o escopo é constituído por dispositivos normativos que versam sobre as políticas de alfabetização nos primeiros anos de escolarização, especialmente voltadas à infância. O estudo aponta que a história da alfabetização está marcada por tensões, disputas e interesses políticos e econômicos que reverberam nos métodos de alfabetização que ‘eclodem’ no país em determinados momentos históricos.

Lipidomics and temporal-spatial distribution of organelle lipid
Authors: Qian Wenjuan , Tang Huiru , Yao Hongyan
Published: January 2025

Background: Lipids are crucial signaling molecules or cellular membrane components orchestrating biological processes. To gain insights into lipid functions and the communication between organelles, it is essential to understand the subcellular localization of individual lipids. Advancements in lipid quantification techniques, improvements in chemical and spatial resolution for detecting various lipid species, and enhancements in organelle isolation speed have allowed for profiling of the organelle lipidome, capturing its temporal-spatial distribution. Objective: This review examined approaches used to develop organelle lipidome and aimed to gain insights into cellular lipid homeostasis from an organelle perspective. In addition, this review discussed the advancements in lipid-mediated inter-organelle communication within complex physiological and pathological processes. Conclusion: With the advancement of lipidomic technologies, more detailed explorations of organelle structures and the specific lipid-mediating functions they perform are feasible.

Published: January 2025

Objectives

Circular RNAs (circRNAs) are known to be associated with cardiovascular diseases. At present, an ideal biomarker for the early diagnosis of coronary heart disease (CHD) is still lacking.

Methods

We screened differentially expressed circRNAs (DEcircRNAs) in the peripheral blood monocytes (PBMCs) of patients with CHD, using the microarray technology in comparing the transcriptome. We identified upregulated and downregulated circRNAs. At the same time, we collected the patient clinical medical records and the PBMCs, the above results were analyzed and validated by quantitative reverse transcription-polymerase chain reaction (qRT-PCR), using 374 patients.

Results

We identified 183 upregulated and 41 downregulated circRNAs. Among these DEcircRNAs, hsa_circ_0000745/hsa_circRNA_101996 was significantly upregulated in a cohort of 297 patients with CHD and 77 non-CHD controls. Among patients with CHD, hsa_circ_0000745/hsa_circRNA_101996 was significantly upregulated in the unstable angina pectoris (UAP) and acute myocardial infarction (AMI) subgroups compared to the stable angina pectoris (SAP) subgroup. By dividing hsa_circ_0000745/hsa_circRNA_101996 expression into quartiles, we observed that the highest hsa_circ_0000745/hsa_circRNA_101996 expression quartile was a risk factor for CHD compared to the lowest quartile (odds ratio [OR]: 2.709; 95 % confidence interval [CI]: 1.126–6.519, p=0.026), after adjusting for the traditional risk factors (age, sex, body mass index [BMI], smoking, alcohol, C-reactive protein [CRP], small and dense low-density lipoprotein [sdLDL] and lipoprotein-associated phospholipase A2 [LP-PLA2]).

Conclusions

These data suggest that upregulated hsa_circ_0000745/hsa_circRNA_101996 in PBMCs is a risk factor for CHD and could be used as a biomarker of CHD.
Mechanism, models, and influence of heterogeneous factors of the microarc oxidation process: A comprehensive review
Authors: Pecherskaya Ekaterina , Golubkov Pavel , Konovalov Sergey , Gurin Sergey , Novichkov Maksim
Published: January 2025

The shortcomings of the microarc oxidation (MAO) technology are revealed, in accordance with which a range of topical scientific problems that need to be solved is formulated. It is shown that, despite significant progress in this area of research, there are still controversial issues related mainly to the features of the emergence and combustion of microdischarges. In order to develop a scientifically substantiated approach to the choice of the optimal mode for deposition of microarc oxide coatings, regularities in the influence of heterogeneous factors on their properties are systematized. The analysis of scientific works devoted to the mathematical description of the MAO process has been carried out. It is shown that the existing mathematical models have limitations, and are applicable only to certain aspects of coating formation and do not describe the MAO process as a whole. The prerequisites, recommendations, and theoretical provisions that can be used in the development of a complex mathematical model of the MAO process are revealed. Known methods of analytical description of the forming curve are considered. The possibility of using the forming curve for determining the correct choice of technological parameters and predicting the oxide coating properties during their formation is shown.
Complementary Organization of Mouse Driver and Modulator Cortico-thalamo-cortical Circuits
Authors: Cassidy Rachel M. , Macias Angel V. , Lagos Willian N. , Ugorji Chiamaka , Callaway Edward M.
Published: January 2025

Corticocortical (CC) projections in the visual system facilitate hierarchical processing of sensory information. In addition to direct CC connections, indirect cortico-thalamo-cortical (CTC) pathways through the pulvinar nucleus of the thalamus can relay sensory signals and mediate cortical interactions according to behavioral demands. While the pulvinar connects extensively to the entire visual cortex, it is unknown whether transthalamic pathways link all cortical areas or whether they follow systematic organizational rules. Because mouse pulvinar neurons projecting to different areas are spatially intermingled, their input/output relationships have been difficult to characterize using traditional anatomical methods. To determine the organization of CTC circuits, we mapped the higher visual areas (HVAs) of male and female mice with intrinsic signal imaging and targeted five pulvinar→HVA pathways for projection-specific rabies tracing. We aligned postmortem cortical tissue to in vivo maps for precise quantification of the areas and cell types projecting to each pulvinar→HVA population. Layer 5 corticothalamic (L5CT) “driver” inputs to the pulvinar originate predominantly from primary visual cortex (V1), consistent with the CC hierarchy. L5CT inputs from lateral HVAs specifically avoid driving reciprocal connections, consistent with the “no-strong-loops” hypothesis. Conversely, layer 6 corticothalamic (L6CT) “modulator” inputs are distributed across areas and are biased toward reciprocal connections. Unlike previous studies in primates, we find that every HVA receives disynaptic input from the superior colliculus. CTC circuits in the pulvinar thus depend on both target HVA and input cell type, such that driving and modulating higher-order pathways follow complementary connection rules similar to those governing first-order CT circuits.
Mapping the greater southeast Asia, the core part of Asia-Pacific or Indo-Pacific: India’s position in it
Authors: Kayal Arnab
Published: January 2025

International politics is inherently more unstable than national politics, and it has been constantly evolving. Unlike national politics, which often follows more predictable patterns, the dynamics of international relations do not operate through simple, one-dimensional causes. Long-term, fixed policies are unsustainable in the global arena, as alliances and rivalries are fluid; there are no permanent friends or permanent enemies. As we enter the 21st century, international politics has entered a new phase, one that cannot be fully explained by past events. After the Cold War, the center of global political power shifted from Europe to the Asia-Pacific, and more specifically to the Indo-Pacific region. This shift marks what could be called the "Asian Century" or, more precisely, the "Indo-Pacific Century," reflecting the growing influence of powerful nations such as China, Japan, South Korea, the United States, India, and ASEAN countries.

Resource Utilization and Cost in Management of Febrile Infants After the 2021 Clinical Guideline
Authors: Dingle Elena , Pelletier Jonathan H. , Forbes Michael L. , Rajbhandari Prabi
Published: January 2025

OBJECTIVE

The 2021 American Academy of Pediatrics clinical practice guideline (CPG) for well-appearing febrile infants aims to promote evidence-based care, reduce practice variability, enhance care quality, and optimize cost. We aimed to examine the trends in resource utilization and cost associated with the evaluation and management of febrile infants aged 8 to 60 days before and after the CPG’s publication.

METHODS

We performed a retrospective cross-sectional study using the Pediatric Health Information Systems Database, covering the periods of August 2019 to July 2021 (pre-CPG) and August 2021 to July 2023 (post-CPG). We analyzed the use of antibiotics, acyclovir, laboratory studies, lumbar punctures (LPs), and hospitalizations before and after the CPG publication.

RESULTS

We identified 33 736 encounters (12 220 pre-CPG and 21 516 post-CPG). After the CPG, there was a decrease in hospitalization (42.6% vs 34.7%, −7.9% [−9.0% to −6.8%]), antibiotic and acyclovir administration (41.9% vs 33.1%, −8.8% [−9.9% to −7.7%]; 9.7% vs 7.3%, −2.4% [−3.1% to −1.8%]), and LP (31.7% vs 21.8%, −9.9% [−10.9% to −8.9%]). Conversely, the use of C-reactive protein (23.7% vs 32.3%, 8.6% [7.6% to 9.5%]) and procalcitonin (40.1% vs 64.5%, 24.4% [23.3% to 25.5%]) increased. Cost remained unchanged. Age-stratified analysis revealed a significant reduction in hospitalization, antibiotic use, and LP in infants aged older than 22 days, whereas infants younger than 28 days experienced a slight increase in delayed diagnosis of bacteremia and sepsis after the CPG.

CONCLUSIONS

After the CPG, hospitalization, antimicrobial use, and LPs decreased in infants aged older than 22 days, indicating that the CPG may be effective in reducing resource utilization. There was a slight increase in delayed diagnosis of bacteremia and sepsis in infants younger than 28 days.

Pre-service Teachers' Adaptability to Disruptive Technologies in English as a Foreign Language Education
Authors: Casimiro Perlaza Luis Felipe , Vega Rosas Sandra Paola
Published: January 2025

Disruptive technologies encompass a range of technological advances that have the potential to challenge established methods and practices. In the context of English as a Foreign Language (EFL), the use of these technologies offers the possibility of addressing students' needs by placing them at the center of knowledge creation, while also providing teachers the opportunity to adapt to the digital environment by learning and applying new digital tools. The purpose of this study is to identify and characterize the adaptability of EFL pre-service teachers to disruptive technologies in their pedagogical practice, through an analysis of the key areas of their graduate profile. This descriptive, quantitative research aims to collect measurable data for statistical analysis from a sample group. The study involved seven participants aged 22 to 25 years. A four-point Likert scale with 40 items was used to assess the seven evaluations of each participant's lesson plans and classroom performance, yielding a total of 49 evaluations. The results demonstrated a gradual inclusion and integration of four fundamental dimensions—EFL competence, EFL teaching and learning, adequacy of the learning environment, and the integration of disruptive technologies in EFL—ensuring the development of digital teaching competencies. The study concluded that the traditional model of EFL teacher education, which emphasizes professional experience, tends to marginalize technological knowledge in pedagogical practice. As a result, this disconnect represents an area of opportunity for innovation in ILE teacher education.
Morpho-phylogenetic evidence for the first freshwater record of Trichoderma protrudens Samuels & P. Chaverri (Hypocreales, Sordariomycetes)
Authors: Dangallo Bernard Paul S. , Bagacay Jan Felnesh Exe V. , Canto Carr Marlo , Velo Jasmine C. , Calabon Mark S.
Published: January 2025

Trichoderma protrudens Samuels & P. Chaverri was originally described from the trunk of Theobroma cacao L. in Kerala, India, in 2008. Morphologically, it is defined by trichoderma‑like conidiophores bearing subulate or lageniform phialides, green subglobose to obovoidal conidia, and the presence of chlamydospores in culture. Multilocus phylogenetic analyses based on ITS, rpb2, and tef1-α sequence data confirmed the iden‑ tity of the isolates from the Philippines as T. protrudens, with robust support values (100% ML, 1.00 BPP) clustering them with the holotype CBS 121320. This study represents the first global record of T. protrudens in a freshwater ecosystem, expanding this species’ known ecological range into aquatic environments. These findings emphasize the ecological versatility of T. protrudens and underscore the importance of further inves‑ tigations into the fungal diversity of freshwater habitats.
Jokowi’s Political Communication: Utilizing Social Media in Winning Gibran as Vice President of Indonesia
Authors: Sutrisno Sutrisno , Tunaerah Linda
Published: January 2025

In the post-Reformasi era, the political dynamic of Indonesia cannot be separated from the role of elites entrenched in various government lines. The 2024 presidential and vice presidential elections also involved political elites, including President Jokowi, especially in winning the eldest son, Gibran. As President, Jokowi has various accesses to socialize with the Prabowo-Gibran work program, which is considered a symbol of the continuity of Jokowi’s program. Using qualitative methods and Roland Barthes’ semiotic theory, this article will analyze the myths in Jokowi’s political communication on social media related to the nomination of Gibran Rakabuming Raka as the 2024 Vice Presidential Candidate. This article produces three main points: denotation, connotation, and myth, and shows Jokowi’s political communication that reflects democracy and neutrality. In addition, the obstacles faced are often transformed into narratives that strengthen his leadership image. This study suggests enhancing the narrative of meritocracy and democracy, transparency in the political process, consistency in national symbols, focus on public issues, and strengthening the image of independent and progressive leadership. This research is expected to provide new insights for political practitioners and researchers in understanding the dynamics of contemporary politics in Indonesia.

Published: January 2025

The wave of science news related to climate change at the global level has become a trending topic of online media coverage during 2022. The purpose of this study is to determine the focus in elaborating science communication through the practice of science journalism in leading online media in the United States and the United Kingdom. The focus of the coverage moved to discuss more specific issues; the phenomenon of heat waves and global carbon. This research was conducted using a quantitative content analysis method. Data was collected through documentation of online media news content throughout 2022. The object of this research is science news articles on climate change issues in the online media The New York Times and The Guardian. The conceptual basis of this research is based on the opinion of Crystle M. Bruno (2020) who classifies the article into three parts; the introduction, the body, and the conclusion. The study found that how information is delivered in online media in the UK and America shows similarities and differences. The root of the equation can be seen in the choice of long-form journalism format. Meanwhile, differences were identified in the variations in preparing the introduction, the body, and the conclusion. More importantly, the direction and development of journalism in America and Britain is moving towards the institutionalization of quality journalism.
Development of antimicrobial bioaerogel based on Zataria multiflora essential oil to extending ground meat shelf life
Authors: Mirmoeini Seyedeh Sahar , Tajik Hossein , Almasi Hadi , Moradi Mehran
Published: January 2025

Active packaging has become increasingly popular in recent years due to its ability to prolong the shelf life of food. This study used a novel bioaerogel composite consisting of Salep and cellulose derived from grape stalk waste as a carrier for loading and then gradually releasing essential oil during storage in active meat packaging. Then the characteristics of two types of aerogels including morphology, density, porosity, water vapor absorption capacity, and viscosity of their precursor hydrogel were investigated. A total of 99.5% of these compounds were identified in Zataria multiflora essential oil (ZMEO). X-ray diffraction and thermogravimetric analysis of cellulose and cellulose-Salep aerogels showed the crystalline structure of cellulose aerogel, with a thermal decomposition temperature of 350 °C. X-ray diffraction analysis of cellulose revealed three prominent peaks at 16°, 22°, and 34°, corresponding to the (110), (200), and (004) crystal planes, respectively. Then, different amounts of ZMEO were loaded on aerogels, and the minimum inhibitory dose (MID) of ZMEO in vapor phase on meat microbiota and Pseudomonas aeruginosa was reported as 256 (µL/Lheadspace). Application of cellulose and cellulose-Salep aerogels with 10 × MID ZMEO per liter headspace of meat package reduced 1.8 and 1.4 log10 CFU/g of total mesophilic bacteria, 2 and 1.6 log10 CFU/g of total psychrotrophic bacteria, and 1.4 and 0.8 log10 CFU/g of total coliform during the 9-day storage in the refrigerator compared to the control samples. Low-value byproducts from renewable resources can be used to produce bioaerogels for packaging applications. These bioaerogels offer cost-effective solution for antimicrobial and antioxidant food packaging.
A COMPETÊNCIA ARTÍSTICA DE PROFESSORES DE ARTES VISUAIS: ESTUDO DE CASO EM PONTA GROSSA (PARANÁ)
Authors: LIMA CAMILA BOURGUIGNON DE , KNOBLAUCH ADRIANE
Published: January 2025

RESUMO: O objetivo deste trabalho é analisar a relação entre a competência artística e os procedimentos didático-metodológicos de professores de Artes Visuais do ensino fundamental II da cidade de Ponta Grossa-PR. Pretende-se refletir, sobretudo, como a apropriação artística dos professores configura a docência em arte no ensino fundamental anos finais. À maneira de Bourdieu, parte-se do pressuposto que a competência artística de professores resulta da combinação entre trajetória social, formação acadêmica e socialização profissional. O estudo de caso é exploratório, com abordagem qualitativa, e busca triangular fontes de ordem bibliográfica, documental e resultantes de aplicação de questionário, observações sistemáticas e entrevista semiestruturadas. O universo compõe-se de quatro escolas periféricas e centrais e os participantes são quatro professores licenciados em Artes Visuais lotados em turmas de 6º ao 9º ano. Constata-se que os esquemas de interpretação dos quais os professores dispõem (o que constitui sua cultura) advém de referências identitárias com a cultura de massa, mas a formação acadêmica é qualificada por uma cifra eurocêntrica que reforça uma concepção hierarquizada da arte (atribuída às tradições da grande/alta cultura). As conclusões apontam que, a despeito dos eixos norteadores para o ensino de arte no Brasil serem de base multicultural, são reservados aos procedimentos didático-metodológicos um modelo de reprodução cultural (dinâmica canônica com artistas e movimentos de expressão iconográfica tradicional europeia e norte americana) e práticas globalmente valorizadas pelo sistema de ensino (culto ao conteúdo, atividades apostiladas e avaliações com finalidade de aplicação direta a vestibulares), contrariando a própria essência artística.
THE ARTISTIC COMPETENCE OF VISUAL ARTS TEACHERS: A CASE STUDY IN PONTA GROSSA (PARANÁ)
Authors: LIMA CAMILA BOURGUIGNON DE , KNOBLAUCH ADRIANE
Published: January 2025

ABSTRACT: This work analyses the relationship between the artistic competence and the didactic-methodological procedures of Visual Arts teachers from secondary schools (students aged 11 to 14) in the city of Ponta Grossa-PR, BR. The aim is to reflect, above all, how the teachers’ artistic appropriation shapes the teaching of art in basic education. In the manner of Bourdieu, it is assumed that the teachers’ artistic competence results from the combination of social trajectory, academic training, and professional socialization. The case study is exploratory, with a qualitative approach, and seeks to triangulate bibliographic and documentary sources resulting from the application of a questionnaire, systematic observations, and semi-structured interviews. The universe is composed of four peripheral and central schools and the participants are four teachers with bachelor’s degrees in Visual Arts working in classes from 6th to 9th grade. It is noted that the interpretation schemes available to teachers (which constitutes their culture) come from identity references with mass culture, but academic training is qualified by a Eurocentric figure that reinforces a hierarchical conception of art (attributed to the traditions of the great/high culture). The conclusions point out that, despite the guiding axes for the teaching of art in Brazil being multicultural, a model of cultural reproduction is reserved for didactic-methodological procedures (canonical dynamics with artists and movements of traditional European and North American iconographic expression) and practices globally valued by the education system (cult of content, textbook activities and tests aimed at direct application to college entrance examinations) contrary to the artistic essence itself.

Published: January 2025

ABSTRACT: The discussion surrounding the body has been a persistent topic across various fields of knowledge, particularly in Physical Education. In Brazil, this debate gained momentum in the 1980s when the field of Physical Education began systematically integrating with the humanities. Within this context, the Brazilian College of Sport Sciences (Colégio Brasileiro de Ciências do Esporte - CBCE) and its main event, the Brazilian Congress of Sport Sciences (Congresso Brasileiro de Ciências do Esporte - CONBRACE), have showcased the research of their participants through Thematic Working Groups (GTTs) since 1997. Therefore, the aim of this research is to analyze the conceptions of the body present in the CONBRACE proceedings from 1997 to 2017. This research employs a quantitative-qualitative approach through document analysis with bibliometric characteristics. To compose the data analysis, the search and selection of texts were based on the presence of the word “body” in the title, abstract, or keywords of the oral communications. The results show that the main conceptions of the body are related to cultural body; existential body; body as machine/organism; body as subject through corporeity; and identity/symbolic body, with a strong alignment of this debate with perspectives from the humanities, social sciences, philosophy, and the arts throughout the investigated period. In conclusion, this study analyzed and presented various trends, which only reality and history, as criteria of truth, will be able to confirm.

Authors: CALBINO DANIEL , NERY DANIELA ALVARES
Published: January 2025

RESUMO: Nos últimos anos, a democracia universitária entrou na agenda dos debates nacionais, em vista das sucessivas intervenções nos sistemas eleitorais das Instituições Federais de Ensino Superior. Estima-se que 45% das universidades federais sofreram algum tipo de ingerência na escolha dos reitores, além de modificações legais em seus processos decisórios. Nesse cenário, marcado pelo enfraquecimento de princípios democráticos, o presente artigo teve por objetivo analisar os impactos das ingerências federais nas práticas de gestão democráticas das universidades federais, entre os anos de 2018 e 2022. Enquanto recorte metodológico, recorreu-se à unidade de análise de 11 universidades mineiras, acompanhadas de pesquisas documentais e questionários com 167 membros de conselhos universitários. Os resultados apontaram que as intervenções, via medidas provisórias e notas técnicas, revogaram práticas democráticas institucionalizadas, como a paridades nas votações internas em universidades. Por outro lado, ainda que a maioria dos conselheiros universitários refutassem a discricionariedade federal para a escolha dos reitores, os discursos da supremacia docente emergiram quando da concordância com as mudanças que reduziram a participação dos discentes e servidores técnico-administrativos nos processos eleitorais. As conclusões apontam para a necessidade de se debater os limites das interferências recentes como também as contradições internas que atravessam historicamente as práticas das universidades, na busca por caminhos mais democráticos.

Abstract Phrynops geoffroanus has a wide distribution in South America, living in aquatic environments such as rivers, streams, and lakes, in natural and urban environments. In this work, the plastron formula and the diversity index associated with the allometric condition are established for the species. For the morphometric analyses, the following were calculated: standard error, class intervals, sample standard deviation, principal component analysis, and allometry. When evaluating the morphometric dependence, r = 0.85 was obtained, which allowed us to verify the allometric classification Y, the growth rate K, and the proportion of growth b for each segment that composes the length of the plastron (LP). Thus, the calculated morphometric set demonstrates that the plastron formula can serve as a diagnostic character for Phrynops geoffroanus. We inferred from this study that the plastron formula can be maintained even in conditions of high environmental degradation.

Abstract Parkinson’s disease (PD) is characterized by progressive loss of dopaminergic neurons in the substantia nigra pars compacta, which leads to a reduction in the production of dopamine. Medication with levodopa becomes less effective as the disease progresses. Despite the excellent results observed in clinical practice with the medicinal use of Cannabis in the treatment of PD, the level of scientific evidence is still limited due to the small number of studies published in this field. We present the case of a 77-year-old man diagnosed 22 years ago with PD in an advanced stage, with significant bradykinesia, tremor, and rigidity along with the inability to maintain an upright position and walk, exacerbated by a femur fracture. He also had advanced dysphagia, resulting in a gastrostomy. Although lucid, he showed no interest in conversation and tended to become depressed and isolated. He used Prolopa® with no satisfactory therapeutic response. After starting treatment with Cannabis sativa oil, he is now able to walk around the house frequently and eat pasty food regularly without choking or broncho-aspiration episodes. There has also been a significant improvement in non-motor symptoms; he is more active, cheerful, communicative, and attentive to his surroundings. Further studies are needed to elucidate these results and the mechanisms of action of cannabinoids through which they exert possible neuroprotective and neuroreparative effects. These compelling results suggest that cannabis oil may offer a valuable and effective therapeutic option for individuals with Parkinson's disease.

ABSTRACT The purpose of the study was to identify the casuistry of papillary mammary neoplasms in female dogs, describe their epidemiological (age, breed) and morphological characteristics, and determine the survival of patients. Overall survival was estimated using Kaplan-Meier curves and comparisons between groups were performed using the Cox Mantel log-rank test (p < 0.05 were considered significant). A study was carried out between 2005 and 2020 at the Laboratory of Comparative Pathology of the Institute of Biological Sciences of the Federal University of Minas Gerais. The study identified 288 female dogs with 353 papillary neoplasms, 36.93% benign (papilloma, sclerosing papilloma, and papilloma with carcinomatous areas in situ) and 63.06% malignant (non-invasive papillary carcinoma, invasive papillary carcinoma, invasive papillary carcinomas with micropapillary areas and micropapillary areas in situ, and solid papillary carcinoma). Papilloma (53.1%) and invasive papillary carcinoma (46.64%) were the most frequent. Most papillary neoplasms were smaller than 3.0 cm in size and presented no metastases in lymph nodes and no distant metastases. However, the invasive papillary carcinomas’ average size was larger than the papillomas and non-invasive carcinomas. Papillary neoplasms are often associated with other types of mammary neoplasms; thus the survival of most female dogs is difficult to determine.

ABSTRACT Follicular fluid is a haven that provides a microenvironment for the development and maturation of oocytes. It is a medium that provides a means of communication within the follicular cells. The role of follicular fluid in the development and maturation of follicles and oocytes involves the actions of certain genes. Here, we examined the impact of CFF on the gene expression of camel oocytes during (IVM). Hypothetically, IVM medium was enhanced with 2.5% CFF, and we analyzed the expression of several genes including Bax, Bcl-2, P53, Acta2, TGFβ, Cx43, and Tagln. Consequently, the follicular fluid from camels had a substantial effect on the mRNA transcript level of the BCL2 gene, which is related to apoptosis. Acta2 and Tagln genes that relate to cytoskeletal protein “actin” in transforming growth factor beta (TGFβ) pathway were also modulated. However, the follicular fluid increased the expression of TGFβ in camel oocytes. This study showcases the beneficial effects of CFF on camel oocyte Gene Expression and provides a platform for studying the many mechanisms involved in oocyte meiosis, particularly those associated with the TGFβ pathway. We recommend using higher dosage and measuring the expression levels of certain genes involved in programmed cell death and inflammation.

ABSTRACT The surge in interest in bioactive plant compounds, particularly from grapes (Vitis vinifera L.), has led to this study on phenolic compounds at different ripening stages. Grapes were collected before veraison, at veraison, and during ripening. Phenolic compounds were extracted using 50% acetone and quantified through spectrophotometric assays for total phenolic, flavonoid, flavanol, condensed tannin, and hydrolysable tannin contents. LCMS/MS identified phenolics. Antioxidant activities were assessed via (DPPH), (ABTS), phenanthroline, reducing power, and silver nanoparticle assays. Additionally, anti-tyrosinase activity and photoprotective effects were evaluated. The results indicated that before veraison (BV) stages yielded the highest concentrations of phenolic compounds. The most abundant compounds at the berry veraison stage were catechin (72645.40, Sabel), gallic acid (1130.75, Red Glob), and luteolin (164.44, Cardinal). Antioxidant activities were consistent with phenolic content trends, with significant tyrosinase enzyme suppression and high SPF factor observed. Principal Component Analysis highlighted strong correlations between phenolic profiles and antioxidant activities. This study is the first to examine how grape ripeness affects phenolic content and biological activities in Algerian grape seeds. It identifies optimal harvest times for maximizing bioactive compounds and supports the use of grape seed extract in sunscreens and antioxidants.

Published: January 2025

Abstract How are the Brazilian new research agendas influenced by the contemporary dissemination of theories challenging colonial ontologies and advocating for critical revitalization of Latin American thought? This article investigates the dominant circuits of academic knowledge production in Brazil to comprehend the impact of decolonial perspectives during the first decade of the reception and adoption of this theory in the country’s intellectual production. By examining 246 articles that explored the terms “decolonial” or “decolonials” published up to 2018, we aimed to analyze the various applications this category had within Brazilian research. The aim is to outline the structure of networks involved in decolonial studies through a bibliometric review of this literature, to provide a partial historical overview of the principal themes, authors, and references mobilized in periodicals registered in the Scopus and Web of Science between 2009 and 2018. The findings suggest that studies associated with decolonial perspectives presented as both analytical and political, organized within the field of social sciences but with a noticeable influence on other knowledge domains.
Da (re)produção do conhecimento à prática gerencial de marketing no Brasil: é possível decolonizar o marketing?
Authors: BATISTA KAREN
Published: January 2025

Resumo Este artigo tem como objetivo discutir, sob uma perspectiva decolonial, como é produzido e reproduzido o conhecimento em marketing no Brasil. Buscou-se demonstrar os aspectos históricos que influenciaram a exportação do marketing dos Estados Unidos para o Brasil como um produto cuja função era disseminar a ideologia neoliberal, num período histórico marcado pela disputa por hegemonia mundial: a Guerra Fria. Com base nas reflexões realizadas, foi possível concluir que, mesmo após tantas décadas, o marketing ainda não se desvinculou das ideologias que o formaram e que, até os dias de hoje, o mainstream ignora as questões políticas e sociais que influenciam tanto sua prática gerencial quanto a academia. São apresentadas algumas direções para futuras pesquisas, no intuito de decolonizar o conhecimento de marketing. Espera-se que este estudo possa contribuir para a emancipação da área, de modo que o conhecimento possa se livrar das amarras ideológicas produzidas pelo processo de colonização epistêmica.

This study investigates the impact of low-temperature annealing treatment at 200°C on the wear resistance and mechanical properties of eutectoid pearlitic steel, commonly used in railway applications. This research primarily focused on understanding the microstructural changes and their correlation with mechanical hardness and wear resistance. Microhardness testing indicated that the hardness of the initial pearlitic microstructure increased from 370 HV to 400 HV following the low-temperature annealing treatment. This increase in hardness was linked to a substantial improvement in wear resistance, evidenced by a 27% decrease in wear rate. Additionally, the low-temperature annealed samples demonstrated a yield strength increase of approximately 21%, albeit with a slight reduction in total elongation. High-resolution Transmission Electron Microscopy analysis post-treatment revealed the emergence of nanoscale transition carbides, needle-type transition carbides, with a hexagonal structure, contributed to an increased nano-hardness of the pearlitic structure from 4.16 GPa to 6.78 GPa. The results suggest that the low-temperature annealing process not only enhances the hardness and wear resistance of pearlitic steel but also induces favorable microstructural changes that could significantly extend the service life of railway components.
