Published: February 2025

IntroductionThe application of selenium could directly or indirectly modulate the activity of antioxidant enzymes in crops, thereby mitigating the detrimental effects of abiotic and biotic stresses on crop health. However, there are few studies on the effects of nano-selenium fertilizer on potato scab caused by Streptomyces spp., potato yield and tuber quality.MethodsWe aimed to elucidate the impact of nano-selenium fertilizer on potato disease resistance, yield, tuber quality, antioxidant enzyme activity and rhizosphere soil bacterial communities, and to determine the optimal frequency and growth stages of nano-selenium fertilizer spraying.Results and discussionThe application of nano-selenium fertilizer twice during the seedling stage significantly reduced the disease index of potato scab, enhanced potato yield, tuber quality (dry matter, Vitamin C, crude protein, and selenium content), and antioxidant enzyme activity (glutathione peroxidase, peroxidase, polyphenol oxidase, superoxide dismutase, and phenylalanine ammonia lyase). The diversity of the rhizosphere bacterial community of potatoes subjected to selenium fertilizer spraying at the seedling stage increased significantly, and concurrently, the symbiotic network of rhizosphere bacterial microbiome grew more complex. Beneficial microorganisms such as bacteria of the genus Bacillus were enriched in the rhizosphere soil. The current study provided theoretical support for the exploration of a potato selenium-enriched technology system and supplies scientific guidance for the utilization of nano-selenium.

ObjectiveThis study examined the relationships between teacher competency, occupational stress, emotional exhaustion, sense of professional achievement, and work engagement among secondary school physical education teachers. It also investigated demographic differences in these variables and tested the structural invariance of the proposed model across genders.MethodA total of 1,347 secondary school physical education teachers participated in the study, completing validated scales to measure the key constructs and providing demographic information such as gender, age, education level, professional title, and school location. Data were analyzed using descriptive statistics, t-tests, one-way ANOVA, correlation analysis, and structural equation modeling (SEM). Mediation effects were assessed through bootstrapping, and structural invariance was tested using multigroup SEM.ResultsDemographic analyses revealed significant differences. Male teachers reported higher competency, professional achievement, and engagement, while female teachers experienced slightly greater emotional exhaustion. Younger teachers and those with lower professional titles reported higher occupational stress and emotional exhaustion. Rural and urban teachers exhibited comparable levels of most variables, except for urban teachers reporting slightly higher emotional exhaustion. Teacher competency directly influenced work engagement (28.27% of the total effect) and indirectly through occupational stress, emotional exhaustion, and professional achievement, with professional achievement being the strongest mediator (25.97% of the total effect). Sequential mediation pathways involving these factors were significant but weaker in magnitude. Structural invariance analysis confirmed that the model was consistent across genders, demonstrating robust applicability across male and female teacher populations.ConclusionTeacher competency is a key driver of work engagement, operating through both direct and indirect mechanisms, particularly by alleviating occupational stress and enhancing professional achievement. These findings underscore the importance of interventions aimed at fostering teacher well-being, including stress management programs and professional development opportunities, while addressing demographic-specific needs. Future research should employ longitudinal designs and consider additional contextual factors to extend these findings.

Published: February 2025

ObjectivesThis study aimed to investigate the impact of socioeconomic status on survival in Chinese patients with acral melanoma.MethodsWe collected clinical and socioeconomic information of 298 primary acral melanoma patients and performed Kaplan–Meier curves, log-rank tests, Cox proportional hazards models, and Pearson’s chi-squared tests to evaluate the relationships between clinical characteristics, socioeconomic factors, and survival outcomes.ResultsAmong the clinical characteristics, age, gender, stage, Breslow thickness, and primary tumor site significantly impacted survival in acral melanoma patients (p = 0.01, p = 0.05, p &lt; 0.01, p &lt; 0.01, p &lt; 0.01, respectively). Compared to individual socioeconomic factors such as education, occupation, medical insurance, and marital status, the socioeconomic level derived from these four dimensions accurately predicted patient survival. Patients with higher socioeconomic status demonstrated significantly reduced mortality risk (HR = 0.60, 95% CI = 0.40–0.91, p = 0.02). However, socioeconomic level was not found to be an independent prognostic factor for acral melanoma patients after multivariable adjustment. Notably, a negative correlation was observed between socioeconomic level and Breslow thickness.ConclusionSocioeconomic level is associated with survival in Chinese acral melanoma patients. However, this association may be attributable to Breslow thickness rather than socioeconomic status itself.

Published: February 2025

BackgroundWHO grade II oligodendroglioma (OG/II) is a rare primary brain tumor with various outcomes. Our study aims to investigate prognostic factors for postoperative OG/II patients and then evaluate the instructional value of tumor size.MethodsWe retrospectively studied the cases from the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate Cox analyses and Kaplan-Meier survival curves were used to identify and assess prognostic factors. The optimal cut-off value of tumor size was determined by X-tile analysis and verified by multivariate analyses. Subsequently, Subgroup analyses were performed based on tumor size.Result676 OG/II patients were enrolled in our study. Multivariate Cox analyses revealed that age &gt; 60 (HR 3.52), male (HR 1.48), total resection (HR 0.38), and tumor size (HR 2.04) were independent factors in predicting cancer-specific survival (CCS). The optimal cut-off value for tumor size was 60 mm. Patients with tumor size less than 60 mm, age &gt; 60 (HR 3.82), and radiation (HR 1.58) were associated with worse CSS, while total resection (HR 0.35) was associated with better CSS. Lastly, a tumor size-based nomogram was established objectively and accurately.ConclusionOur study identified four crucial prognostic factors related to CSS in postoperative OG/II patients: age, sex, the extent of recession, and tumor size. A tumor size of 60 mm was an optimal cut-off point for dividing patients into low and high-risk groups. Patients in the low-risk group may not benefit from extended resection and radiation. Tumor size can be a valuable factor for making therapeutic schedules.

Published: February 2025

ObjectivesTo examine cancer mortality rates in Colombia by ethnic groups (Indigenous, Rom, Raizal, Afro-Colombian, and Mestizo) and assess trends from 2011 to 2022.MethodsNational vital statistics from death certificates and the Colombian census data were used. Crude and direct age-standardized mortality rates were determined by ethnicity for the study period, by year, sex, and cancer type and Joinpoint analysis was conducted to examine trends.ResultsAge-standardized cancer mortality of Mestizos (60.1 per 100,000 population) was lower than in Rom and Raizales (557.3 and 77.7 per 100,000), and higher than for Afro-Colombians and Indigenous (37.2 and 20.0 per 100,000). Indigenous people in Colombia had greater proportions of individuals under 45 dying of cancer than Mestizos (18.7% vs. 9.7%, p-value = &lt;0.01). Compared to the Mestizo population, Raizales and Afro-Colombians experienced disproportionately higher age-standardized mortality rates due to prostate cancer (26.6/100,000 and 8.6/100,000 vs. 8.1/100,000), and for Raizales and Rom breast cancer (14.0/100,000 and 103.2/100,000 vs. 9.1/100,000).ConclusionThe disparities in cancer mortality in ethnic minorities in Colombia call for investigating cancer etiology and access to care among the Rom and the Raizal populations.

Le folklore breton, aux sources du romanesque de Paul Féval
Authors: Rivasson Félicité de 
Published: February 2025

Cet article explore comment l’œuvre de Paul Féval intègre et transforme les légendes et croyances populaires bretonnes pour façonner un imaginaire romanesque distinctif. Féval, né à Rennes en 1816, a été marqué par les traditions orales de sa région natale. Il a puisé dans ce riche patrimoine culturel pour créer des œuvres mêlant fantastique, merveilleux et romantisme, telles que la Femme blanche des marais, les Belles-de-nuit, et la Fée des Grèves. Ces récits illustrent une hybridation entre des éléments de folklore authentique et des réinterprétations littéraires influencées par le romantisme européen. Féval s’intéresse particulièrement aux figures féminines légendaires liées à l’eau et à l’Autre Monde, telles que la Femme blanche des marais, un spectre protecteur des Malestroit, ou encore les Belles-de-nuit, revenantes pleurant leur destin tragique. Ces personnages ne se contentent pas d’enrichir l’arrière-plan poétique  : ils participent activement à l’intrigue et cristallisent l’introduction du merveilleux moderne, où le surnaturel surgit dans un cadre réaliste et provoque fascination et trouble. Le romancier explore également la figure de la fée, comme dans la Fée des Grèves, où cette créature aquatique romantique, à la fois protectrice et ambiguë, traverse des seuils symboliques entre vie et mort, terre et mer. La fée, souvent associée à des forces naturelles et parfois christianisée, reflète l’imaginaire breton en perpétuelle transformation. En outre, cet article met en lumière la manière dont Féval utilise les légendes pour répondre aux attentes d’un public élargi, avide d’un merveilleux accessible et enraciné dans une réalité géographique et historique. Ce processus inclut l’adaptation des récits traditionnels pour les rendre compatibles avec le roman-feuilleton, genre qui valorise intrigue et mystère. Enfin, cet article souligne la fonction idéologique de ces récits  : réenchanter un monde moderne perçu comme désenchanté par l’industrialisation et la montée du matérialisme. Les légendes retravaillées deviennent ainsi un outil narratif et poétique permettant à Féval de célébrer un passé empreint de spiritualité et de mystère, tout en critiquant une société en pleine mutation.

Published: February 2025

Abstract
Convex and concave channel structures are formed due to the increase in the number of layers of 3D NAND flash, along with the limitations of the technology to etch holes in the channel. Program, interference, and retention characteristics of convex and concave structures are investigated. The program and interference characteristics are improved in the convex structure due to the concentrated E-field in the word line. The retention characteristics are improved in the concave structure due to the dispersed E-field. In addition, various space materials are considered to confirm cell characteristics according to the dielectric constant, and it is found that these characteristics are improved when air space is used.

Published: February 2025

Abstract
Ultrasound cavitation finds diverse applications across biomedical engineering, chemical processes, and industrial systems. Its effects significantly influence the performance of ultrasound imaging and targeted drug delivery. Although microbubbles have been found to enhance cavitation activity, their effect is practically insufficient. To enhance cavitation activity, we introduce a composite structure utilizing chitosan nanoparticles as a stabilizing shell. The relationship between chitosan nanoparticle size and the initial concentrations of chitosan and sodium tripolyphosphate linker is systematically analyzed. The cavitation effect associated with these chitosan nanoparticle-shelled composites is assessed using iodide dosimetry under ultrasonic irradiation at 20 kHz. Composites encapsulated by a positively charged chitosan nanoparticle shell, measuring 23 nm in size, demonstrate significant improvements in hydroxyl radical generation compared to untreated samples, indicating enhanced acoustic cavitation. These findings highlight the potential of combining chitosan nanoparticles with microbubbles for versatile applications ranging from ultrasound imaging to drug delivery.
