Abstract The paper aimed to analyse the scientific productions in the Arts field within strictu sensu Postgraduate programs at the master level in Roraima. It utilized a primarily qualitative approach, through documentary research in the academic portals of six Postgraduate programs of the state. After the collection, twenty-three theses produced between 2018 and 2022 were analysed. The analysis revealed gaps to be explored, the need for the creation of a postgraduate program specific in Arts in Roraima, besides the importance of the conducting and disseminating research that deconstructs stereotypes about the region, and the artistic and cultural richness of the state.
Single-layer woven carbon fibers improved the thermal and mechanical properties of epoxy resin
Authors: Reyes-Mayer Adriana , Romo-Uribe Angel
Published: February 2025

Epoxy EPON 828 was reinforced with a single layer of carbon fiber fabrics and exhibited significant increase of thermal and mechanical properties. Two fabric types, twill 2/2 and 4-harness satin (4HS), were investigated. Epoxy of diglycidyl ether of bisphenol-A/epichlorohydrin, EPON 828 was cross-linked with 4,4’-diaminodiphenylmethane. The thermal decomposition temperature, Tdec, and the glass transition temperature, Tg, of the composites were increased relative to the neat epoxy, and the 4HS fabric increased Tdec and Tg over 60 K. The twill fabric increased fourfold the tensile Young’s modulus E and twofold the flexural modulus E’. In contrast, when adding a nonwoven glass fiber fabric, the tensile modulus only increased twofold, thus highlighting the unique reinforcement effect of woven carbon fibers. Scanning electron microscopy showed that the epoxy resin was well dispersed within the carbon fiber fabrics and the absence of matrix–fiber debonding indicated an efficient stress transfer between epoxy and carbon fibers. Dynamic mechanical analysis showed a shift to higher temperatures of the α mechanical relaxation, and the intensity of the mechanical damping was attenuated denoting restricted macromolecular motions, and this may explain the enhanced thermal and mechanical properties.

Authors: Myers Holly , Toglia Daphne
Published: February 2025

This protocol details index matching for delipidated whole mouse brain samples in ethyl cinnamate solution to prepare for lightsheet imaging. Upon completion of this protocol, the delipidated mouse brain should be a light amber color and appear translucent when immersed in ethyl cinnamate. This index matching protocol may be paired with a modified iDISCO delipidation protocol: Whole Mouse Brain Delipidation - Dichloromethane. Ethyl cinnamate is an inexpensive, effective, and lower-toxicity index matching option that may be used in place of index matching reagents typically paired with this delipidation protocol (Hildebrand et al, 2019).
MODELING OF PERSONAGE’S FICTIONAL CONSCIOUSNESS IN DRAMA L. STARYTSKA-CHERNYAKHIVSKA “ON THE EVE”
Authors:   National Center "Junior Academy of Sciences of Ukraine", Kyiv, Ukraine, Atamanchuk Viktoriia
Published: February 2025

The article is devoted to the study of means of artistic construction of the personages’ consciousness in the play “On the Eve” by L. Starytska-Chernyakhivska. The parameters of modeling the personage’s fictional consciousness as a phenomenon that changes external circumstances, affects the essence of internal experiences, which contribute to the formation of new levels of understanding of the personages, are analyzed; the correlations between personages’ fictional consciousness and the external fictional world is traced through the understanding of new meanings as a basis for the formation of new contexts and forecasts. It was determined that the fictional consciousness of the main character constructs the development of events in the drama, as the character formulates ideas that significantly influence the worldview of other actors in the drama. It is proved that in the drama fictional consciousness of a maim hero is constructed through the character’s awareness of his own individuality, caused by his creative self-expression, as a fact of his own existence and vocation. Shevchenko’s artistic works resonate with the mood of jther personages and become an artistic expression of feelings of the protagonists. The reactions of each of the participants to Shevchenko’s words, with the help of which the author constructs the fictional consciousness of the heroes, are mutually reinforced. It was determined that the fictional consciousness of the main character turns out to be the center of focusing, understanding and artistic reproduction of the most important problems of the day in the drama “On the Eve”, it acts as a determining factor in the formation of the artistic structure of the play. The appearance of the poet crystallizes previously defined meanings and gives new impulses to the unfolding of the dramatic action. Episodes of the highest intensity, which direct the actors to the realization of the most important truths and determine the states of deep insights, are directly related to the image of Taras Shevchenko. The phenomena and processes of objective reality, reflected in Shevchenko’s consciousness, acquire symbolic meaning through the highlighting and strengthening of deep patterns that the great poet makes clear to others.

Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, DYACHENKO Svitlana , REDCHYTS Iryna ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: February 2025

Background . Participatory budgeting is an innovative tool for public engagement that contributes to the democratization of local financial management. In Ukraine, this mechanism is considered an important element of strengthening local democracy and transparency in the decision-making process. However, despite positive trends, the development of participatory budgeting remains limited due to the fragmented regulatory framework, lack of consistency in its implementation, and low level of public awareness. The article presents an analysis of the current regulatory framework for the budget participation in Ukraine, key problems were identified and ways to solve them were proposed, taking into account international experience.

Methods . The research was conducted using qualitative and quantitative analysis of the regulatory acts governing participatory budgeting in Ukraine. A case-study method was employed, specifically analyzing participatory budgeting models in Brazil, Poland, and other countries. The assessment of the strengths and weaknesses of the regulations was based on expert surveys of local government officials, non-governmental organizations, and researchers. A crucial research tool was the review of literature, international recommendations, and reports on the implementation of participatory budgeting.

Results . The analysis showed that Ukraine lacks a special profile law that would regulate the participatory budgeting process. Instead, various subordinate regulations operate, which cause heterogeneity of practices in different regions. International experience demonstrates that successful participatory budgeting systems are based on clear legislative norms and active public involvement. Among the strengths of the current system in Ukraine, initiative at the local level can be highlighted, while among the weaknesses is the lack of a systemic approach and uncertainty about responsibility for project implementation.

Conclusions . For the effective implementation of participatory budgeting in Ukraine, it is necessary to adopt a separate law that clearly defines the rights and responsibilities of all stakeholders. Increasing public awareness and utilizing digital technologies to ensure transparency and engagement are also crucial. The adoption of best practices from international experience will enable Ukraine to build a sustainable and inclusive system of participatory budgeting

Published: February 2025

Além do consumo de matérias-primas não renováveis, o crescimento no setor da construção civil provoca uma elevada geração de resíduos, danosos ao meio ambiente no contexto do descarte irregular. Mirando um desenvolvimento sustentável pautado na redução de tais impactos, tecnologias como a reciclagem de resíduos de construção e demolição foram desenvolvidas de maneira tal a possibilitar a substituição dos agregados naturais do concreto por agregados reciclados. As diferentes características e propriedades desses materiais, no entanto, sugerem também mudanças de comportamento. Sendo assim, a presente pesquisa propõe comparar os efeitos da corrosão acelerada em concretos convencionais e concretos com substituições, em seu traço, de 25% e 50% de agregados graúdos naturais por graúdos reciclados. Inicia-se o trabalho na caracterização físico-química dos componentes utilizados na fabricação dos concretos a fim de identificar suas propriedades, determinação realizada mediante ensaios normatizados. As massas especifica e unitária do agregado reciclado apresentaram valores menores, porém a absorção de água foi, aproximadamente, 47 vezes maior que a do agregado natural. Obtidas as características, foi possível determinar o traço a ser utilizado conforme o método de dosagem ABCP/ACI. Definido o traço, corpos de prova com substituições realizadas por massa foram moldados e, então, submetidos a ensaios de compressão e absorção de água por imersão. O método de corrosão acelerada por imersão modificada foi utilizado para comparar a perda de massa no aço pela ação de íons cloreto. Enfim, a análise dos resultados obtidos demonstrou comportamentos mecânicos semelhantes para ambas as formulações, sendo os concretos de agregados reciclados menos suscetíveis à corrosão acelerada.

Published: February 2025

This article explores the integration of pedagogical and philosophical principles into the water resources classification framework, with a specific focus on the concept of the "River We Want." The study presents a real case conducted by the Interdisciplinary Center for Environmental Sanitation Studies (NIESA), in collaboration with the Public Prosecutor’s Office of the State of Mato Grosso (MPMT) and the “Alto Rio Cuiabá Basin Committee” (CBH Alto Rio Cuiabá), where an approach based on the ethics of community participation and the construction of participatory knowledge was applied with the aim of defining the desired water uses in the UPG-P4 basin, involving relevant stakeholders to support alternative classifications in the regions of Cuiabá, Barão de Melgaço, and Nobres. The methodology involved educational presentations on the conceptual aspects of water resources classification, the availability of supporting material on the NIESA website, and interactive in-person sessions where participants were guided to use basin maps and stickers representing different water uses to express their desired future scenarios. The results reveal the influence of users' socioeconomic interests on their desired water uses for the rivers in their respective regions. The study discusses how the applied methodology promoted collective socio-environmental awareness and responsibility among users regarding the multiple uses of water resources. The article concludes by reflecting on the implications of this approach for future water resources classification initiatives.

Authors: Vaishna T. , Radhakrishnan V.V. , Resmi L.
Published: February 2025

Cowpea is a major legume crop native to Africa and it provides food for man as well as livestock. Even though it is widely cultivated in Africa, a second domestication was probably occurred in Asia. Cowpea can thrive in a range of soil types, pH and temperatures. Besides, changing lifestyle and climate variability have brought in enough scope for its cultivation. Variability studies in cowpea are highly significant in order to identify superior genotypes for the further improvement of the crop. The genetic diversity analysis will help in the identification of potentially distinct genotypes with contrasting traits which can be used to operate effective selection of genetically diverse genotypes for yield improvement as well as nutritional enrichment and climate resilience. Hence, the present review is focused on the studies carried out in different parts of the world to characterize the genetic diversity in cowpea germplasm. This work was done at the Department of Botany, University of Calicut, Kerala. The study reviewed and systematically evaluated the various practices implied to assess the genetic diversity in cowpea. Literature search was done during March, 2023- July, 2024. About 150 Research papers were screened from various data bases like Google scholar, ResearchGate and a total of 79 research papers were used to write this review article. Present review article reveals the significance of cowpea as a food and fodder crop and the characterization of cowpea genotypes as an important genetic resource for developing climate resilient crops. The review also shed light on origin and distribution of cowpea, cowpea breeding, tools for genetic variability assessment among cowpea genotypes, new and improved molecular markers that are utilized in research and future aspects of cowpea improvement for maintaining sustainable nutrition to society.
De Perjura a Guachuchera: apropiación transnacional de una canción romántica del México porfiriano en el Chile del Centenario
Authors: Cornejo Tomás
Published: February 2025

El artículo discute las interpretaciones historiográficas y musicológicas de la canción Perjura, compuesta por Miguel Lerdo de Tejada en 1901, considerada la primera canción romántica mexicana, para lo cual se enfatiza en las condiciones de producción y en el contexto cultural del México porfirista. Se destaca el surgimiento de un mercado de bienes simbólicos centrado en la música, que intentaba llegar a un público socialmente transversal. Desde la historia cultural se rastrea la recepción social de Perjura por medio de su identificación en cancioneros populares impresos y hojas volantes en México y en Chile, donde se analiza la adaptación de su letra y las resignificaciones de que fue objeto, acorde con los cambiantes públicos entre los cuales circuló, destacando aquí el movimiento obrero y el ambiente prostibulario chileno de la década de 1910.
Santiago Londoño Londoño: itinerario ideológico y político de un centenarista liberal en el Viejo Caldas, Colombia
Authors: Martínez-Castillo Héctor Alfonso
Published: February 2025

Por medio del perfil político e ideológico del médico antioqueño Santiago Londoño Londoño (1876-1950), uno de los principales líderes liberales del Viejo Caldas a inicios del siglo pasado, se busca comprender, a escala regional, el clima político de la generación centenarista, las dinámicas asociativas de librepensamiento y las acciones orgánicas partidistas experimentadas en una ciudad de provincia como Pereira. La vida pública de Londoño permite entender su influencia en la configuración ideológica e intelectual de librepensamiento en la ciudad, así como la circulación de ideas, tensiones y prácticas en el marco normativo de la Hegemonía Conservadora. El método biográfico y el análisis discursivo de los enunciados de Londoño con su respectiva contextualización histórica, se acompañan de un abordaje sistemático de prensa, documentación institucional y crónicas de la época donde se rastrea el itinerario políticoideológico del médico. La hipótesis central es que la experiencia política y asociativa de Santiago Londoño permite analizar cómo sus actividades políticas y de asociación pasaron por transformaciones propias del clima político, cultural e intelectual de inicios del siglo XX. Se concluye que Londoño se mantuvo en contacto con el clima político e intelectual de su época a través de las redes de sociabilidad intelectual y partidista, que fueron importantes para que una ciudad de provincia como Pereira experimentara a baja escala su propio clima político e intelectual.

Authors: Garzón-Ochoa Edward Aurelio , Rincón-Ramírez Aura V.
Published: February 2025

Este artículo analiza los procesos de monumentalización en El Castillo, Meta-Colombia, realizados por instituciones oficiales, ONGs, defensores de derechos humanos y familiares de víctimas, dentro del marco de la justicia restaurativa. Estos procesos buscan abordar la violencia que ha marcado la región, utilizando el espacio público para narrar eventos históricos recientes que van desde la colonización hasta la influencia de la Unión Patriótica, abarcando también la militarización y paramilitarización del área, con graves consecuencias como asesinatos, desplazamientos y desapariciones forzadas.
Se adoptó un enfoque cualitativo, que incluyó diálogos de saberes, análisis de archivos, entrevistas semiestructuradas y recorridos por los monumentos, además de observación participante. Estas herramientas permitieron comprender las percepciones y el impacto de los procesos de monumentalización, resaltando cómo las iniciativas comunitarias promueven un sentido de pertenencia y reivindican valores éticos, educativos y políticos del pasado. El estudio contrasta estas iniciativas con proyectos como el Parque y la Casa de la Memoria, diseñados e impuestos por agentes externos, incluyendo arquitectos, artistas, abogados e ingenieros, lo que ha generado discrepancias en el diseño y desconexión con las comunidades destinatarias. Esta situación se manifiesta en el deterioro de estos espacios y resalta el incumplimiento de una verdadera reparación integral.

Published: February 2025

This study presents the complexity and sensitivity of chaotic system dynamics in the case of the double pendulum. It applied detailed numerical analyses of the double pendulum in multiple computing platforms in order to demonstrate the complexity in behavior of the system of double pendulums. The equations of motion were derived from the Euler-Lagrange formalism, in order to capture the system's dynamics, which is coupled nonlinearly. These were solved numerically using the efficient Runge-Kutta-Fehlberg method, implemented in Python, R, GNU Octave, and Julia, while runtimes and memory usage were extensively benchmarked across these environments. Time series analyses, including the calculation of Shannon entropy and the Kolmogorov - Smirnov test, quantified the system's unpredictability and sensitivity to infinitesimal perturbations of the initial conditions. Phase space diagrams illustrated the intricate trajectories and strange attractors, as further confirmation of the chaotic nature of the double pendulum. All the findings have a clear indication of the importance of accurate measurements of the initial condition in a chaotic system, contributing to an increased understanding of nonlinear dynamics. Future research directions are faster simulations using Numba and GPU computing, stochastic effects, chaotic synchronization, and applications in climate modeling. This work will be useful for understanding chaos theory and efficient computational approaches in complex systems of dynamical nature.

Abstract
Introduction: Coronavirus disease (COVID-19) is a newly discovered infectious disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which can affect individuals of all ages. The high positive number of COVID-19 cases in Surabaya and the proportion of teenagers in society is quite large. This study examined the knowledge of teenagers in Surabaya about COVID-19 and prevention behavior.
Methods: This descriptive study used a cross-sectional design and an online questionnaire (Google Forms). The target sample was teenagers aged 10-19 years old who live in Surabaya. A total of 122 respondents were involved (n=122). Sampling was performed using the consecutive sampling method, and the data was processed using the International Business Machines Corporation (IBM) Statistical Package for Social Sciences (SPSS) version 19.0 using univariate and bivariate analysis (p=0.367).
Results: The results showed that most respondents had good knowledge (72.1%) and good behavior (89.3%) regarding COVID-19. No significant relationship was found between knowledge and behavior to prevent COVID-19 among adolescents who live in Surabaya (p=0.367).
Conclusion: This study revealed that most respondents had good knowledge and prevention behavior. Due to a limited number of samples, a larger sample would have provided a more thorough representation of the population and resulted in more accurate outcomes.
Atherosclerosis and Chronic Apical Periodontitis: Systematic Review and Meta-Analysis
Authors: León-López María , Cabanillas-Balsera Daniel , Martín-González Jenifer , Sánchez-Domínguez Benito , Saúco-Márquez Juan J , Segura-Egea Juan J.
Published: February 2025

Background. Atherosclerosis is a chronic and progressive condition of the arteries, characterized by the thickening and hardening of their walls due to the formation of atherosclerotic plaques. Low-grade inflammation is implicated in the pathogeny of atherosclerosis. Chronic apical periodontitis (CAP), the chronic inflammation around the root apex of infected teeth, is associated with a low-grade inflammatory state, so a connection between atherosclerosis and CAP have been suggested. The aim of this study was to conduct a systematic review with meta-analysis to answer the following PICO question: In adult patients, does the presence or absence of atherosclerosis affect the prevalence of CAP? Methods. The PRISMA guidelines were followed to carry out this systematic review. A bibliographic search was performed in PubMed-MEDLINE, Embase, and Scielo. Inclusion criteria selected the studies presenting data on the prevalence of CAP in patients diagnosed with atherosclerosis and control patients. The statistical analysis was carried out using RevMan software software. Study characteristics and risk ratios with 95% confidence intervals (CIs) were extracted. Random-effects meta-analyses were performed. Risk of bias was assessed using the Newcastle-Ottawa scale, adapted for cross-sectional studies. To estimate variance and heterogeneity between trials, the Higgins I2 test was used. The quality of the evidence was evaluated using GRADE. Results. The search strategy recovered 102 articles, and only five met the inclusion criteria. Meta-analysis showed and overall OR = 2.94 (95% CI = 1.83 – 4.74; p < 0.01) for the prevalence of CAP among patients with atherosclerosis. The overall risk of bias was moderate. The quality of the evidence showed a low level of certainty. Conclusions. Patients with atherosclerosis are almost three times more likely to have CAP. This finding supports the hypothesis that chronic inflammatory processes in the oral cavity could significantly impact cardiovascular health, emphasizing the importance of an integrated approach to oral and systemic health care. This result should be translated to daily clinical practice: the healthcare community should be aware of this association and suspect atherosclerotic pathology in patients who show a high prevalence of CAP. Likewise, patients with atherosclerosis should be monitored in the dental clinic for CAP.

Procedimiento iterativo de integración por partes y la evaluación de su eficacia en el aula
Authors: Macías Díaz Jorge Eduardo , Abreu Terán Miguel Ángel , Román Loera Alejandro
Published: February 2025

En este trabajo se evaluó una estrategia simple para aplicar iterativamente la regla de integración de Leibniz desde cálculo elemental a problemas operativos. La regla de integración de Leibniz (también conocida como “fórmula de integración por partes”) es una fórmula relativamente simple. Sin embargo, algunos problemas típicos de cálculo de antiderivadas requieren aplicar esta fórmula de forma iterativa. Lamentablemente, este proceso provoca soluciones erróneas y que requieren mucho tiempo por las diversas aplicaciones de la regla de Leibniz y la complejidad de los cálculos. La estrategia propuesta en el presente trabajo reduce el tiempo empleado para obtener las soluciones de aquellos problemas iterativos. Además, el procedimiento empleado es simple, fácil de describir algorítmicamente y produce resultados más rápidos. Para mostrar la eficiencia de esta estrategia, se realizó un estudio experimental con un grupo de estudiantes de pregrado de ingeniería en una universidad pública de México. La capacidad de estos estudiantes para utilizar reglas elementales de integración se demostró mediante una prueba preliminar y el grupo se dividió en dos subgrupos, a uno de los cuales se le enseñó la regla tradicional de Leibniz, mientras que el segundo aprendió la estrategia estudiada en este trabajo. Los resultados mostraron que el enfoque actual produce resultados decisivamente más rápidos que el método tradicional.

Colonial Regulation on Education Management of Christianity in Indonesia Before Ethical Policy Period
Authors: Badaruddin Kemas , Zaila Siti , Salsabila Mirrah , Ramadhan Syahrul
Published: February 2025

The field of education in the colonial era is often studied in the context of the implementation of the Ethical Policy, one of which is based on the speech of Queen Wilhelmina in 1901 which emphasized that the Netherlands is a Christian country and is committed to helping the mission of that religion. This research attempts to answer the formulation of questions about political policies in Christian education management prior to the Ethical Politics period. The methodology used is a historical research type by going through literature searches, evaluating, verifying, and synthesizing evidence from the data collected. The results of this study indicate that education management policies have been pursued by the Vereenigde Oostindische Compagnie (VOC) since the early 17th century, where due to the influence of religious wars, this trading partnership also tried to replace Portuguese domination and Catholicism in Indonesia. The form of education in that era was still simple to teach obedience and religious rituals in individual teaching without class levels. Apart from a shortage of experienced educators, Dutch language was less popular than Portuguese and Malay. After the company collapsed in 1799, the Dutch government was neutral towards religious affairs since 1808. This caused many "Zending" (Protestant Evangelism) bodies to spread religion as well as establish a number of educational institutions as happened in Minahasa (since the 1830s) and in Batak lands (since the 1860s).

Published: February 2025

Background:

A lumbosacral hemivertebra (LSHV) presents a complex challenge in treating congenital scoliosis. Previous studies have proven the effectiveness of posterior LSHV resection. However, they have primarily focused on coronal balance, neglecting the sagittal alignment, which is crucial for spinal function. The aim of this retrospective study was to assess preoperative sagittal imbalance in patients with an LSHV and to evaluate the evolution of sagittal alignment following posterior hemivertebra resection and short-segment fusion.

Methods:

A retrospective analysis was performed that included 58 patients with LSHV who underwent posterior LSHV resection between 2010 and 2020 and had a mean follow-up duration of 7.5 years. All patients were Han Chinese, and 30 of the 58 patients were female. The mean age was 7.3 years. Sagittal balance parameters were measured preoperatively and at multiple postoperative time points. Clinical outcomes were assessed with use of the Scoliosis Research Society (SRS)-22 questionnaire.

Results:

Preoperatively, 60.3% of patients presented with sagittal imbalance (defined as a sagittal vertical axis [SVA] of >20 mm). Postoperatively, the mean SVA significantly improved, decreasing to <20 mm at the 1-year follow-up (p = 0.016). The pelvic incidence-lumbar lordosis mismatch (PI-LL) also showed significant improvement at the immediate postoperative time point (p = 0.012) and at the last follow-up (p = 0.013). Patients who underwent anterior column reconstruction demonstrated better postoperative global sagittal balance than those who did not (SVA, p = 0.015; PI-LL, p < 0.001). SRS-22 total, self-image, and satisfaction scores significantly (p < 0.001) improved postoperatively.

Conclusions:

This study highlighted the prevalence of preoperative sagittal imbalance in patients with an LSHV and emphasized the impact of LSHV resection (particularly when accompanied by anterior column reconstruction) in achieving postoperative sagittal balance and in enhancing patient quality of life during the long-term follow-up period.

Entrapment of Extensor Hallucis Longus Tendon Following Closed Fracture of the Lower-Third Tibia in an 11-Year-Old Child
Authors: Gupta Khyati , Bhaskar Atul
Published: February 2025

Case:

An 11-year-old girl presented 8 months after conservative treatment of lower third fracture tibia with inability to extend the great toe. There was no neurovascular deficit. Radiograph showed a liner lucent band in the callus. Magnetic resonance imaging confirmed an entrapped, thinned out, intact extensor hallucis longus (EHL) tendon passing through a tunnel in the lower tibia. Surgical decompression was undertaken and tendon freed from bone.

Conclusion:

This is the first reported case of EHL entrapment following closed distal fracture of the tibia in the pediatric age group. We demonstrate full recovery of extensor at 1 year of review.

Authors: Tse Shannon , Piña Dagoberto , Hisatomi Lauren A. , Shahzad Hania , Khoo Kendrick , Parhar Kanwar , Le Hai V.
Published: February 2025

Case:

We report a 9-month-old girl who was involved in a motor vehicle collision and sustained atlanto-occipital dislocation (AOD), atlantoaxial instability, and a C2 synchondrosis fracture. Initial management with a halothoracic vest for damage control failed to maintain reduction, necessitating definitive posterior occipitocervical fusion.

Conclusion:

Traumatic AOD is a rare injury, most common in children following high-energy trauma. Early diagnosis and timely intervention are imperative for improved clinical outcomes. Even in young patients with small anatomy, with careful preoperative planning, occipitocervical fusion is effective and safe with successful postoperative outcomes.

Although several studies have highlighted the significant role of DMRTA2 in several cancers, its specific function and the underlying mechanisms in glioma remain unclear. CRISPR data was leveraged to identify DMRTA2 as a key candidate. We utilized bulk-tumor, single-cell, and spatial sequencing to explore the role of DMRTA2 in glioma malignancy and its possible mechanisms. Glioma specimens were used to assess DMRTA2 expression. In vitro and in vivo experiments were performed to validate the role of DMRTA2 in glioma malignancy and its possible mechanisms. Drug prediction and molecular docking were also conducted. We found that DMRTA2 was markedly upregulated and was identified as an independent prognostic marker. Moreover, single-cell and spatial sequencing analysis demonstrated that DMRTA2 was mainly localized in glioma cells. We constructed a malignant regulatory network for DMRTA2, with the JAK-STAT pathway as a central bridge. In vitro and in vivo experiments confirmed that DMRTA2 promoted the malignant behavior of glioma cells by activating the JAK2-STAT3 pathway. Additionally, DMRTA2 was significantly correlated with genomic mutation. Drugs potentially targeting DMRTA2 were screened and docked to DMRTA2. Taken together, DMRTA2 promotes the malignant progression of gliomas by activating the JAK2-STAT3 pathway and serves as a prognostic marker.
