The study aims to examine the impact of physical exercise on sleep quality among college students and elucidate the mediating roles of self-efficacy and emotional control in this relationship. Data were obtained from the 2024 China College Students' Physical Activity and Health Tracking Survey (CPAHLS-CS). A sample of 10,970 college students was included. Physical exercise levels were measured using the Physical Activity Rating Scale-3 (PARS-3), sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), self-efficacy was measured using the General Self-Efficacy Scale (GSES), and emotional control was assessed using the Adolescent Psychological Resilience Scale. Regression analysis and Bootstrap mediation analysis were employed to test the hypothesised relationships. (1) The direct effect of physical exercise on sleep quality was not significant (β = 0.011, P > 0.05). However, the total effect was negative (β = -0.056, P < 0.001), indicating that indirect effects comprised the predominant mechanism. (2) Self-efficacy (effect size = -0.024) and emotional control (effect size = -0.022) each independently mediated the relationship between physical exercise and sleep quality. (3) In the pathway through which physical exercise influences sleep quality, self-efficacy, and emotional control functioned as independent mediating variables. Specifically, physical exercise indirectly improved sleep quality by enhancing self-efficacy while positively impacting sleep quality through a distinct mediating mechanism involving strengthening emotional control. This study demonstrates the influence of physical exercise, self-efficacy, and emotional control on sleep quality. The findings suggest that physical exercise indirectly optimises sleep quality through a dynamic and synergistic mechanism involving the enhancement of self-efficacy and emotional control. This study provides theoretical support and practical pathways for sleep quality interventions in college students.

Objective This study aimed to investigate the impact of physical activity (PA) on emotional management ability (EMA) in college students and to analyze the chain mediating roles of psychological resilience (PR) and health literacy (HL) in the relationship between PA and EMA. Methods Demographic information was collected using a stratified, cluster, and multi-stage sampling method. Data on PA, PR, HL, and EMA among college students were collected using an online questionnaire. A total of 13,590 valid questionnaires were obtained. Results A significant positive correlation was found between PA and EMA in college students ( r  = 0.177, P  < 0.01). PR and HL played significant mediating roles in the relationship between PA and EMA. The mediation effect consisted of independent mediation by PR and HL and a chain mediation effect between the two. The values of the independent mediation effects and the chain mediation effect were 0.011, 0.010, and 0.004, respectively. The chain mediation effect was lower than each of the individual mediation effects and showed a statistically significant difference compared to the mediation effect of HL ( P  < 0.05). Conclusion PA significantly enhances college students’ EMA through direct effects and a chain mediation pathway involving PR and HL. Coordinated interventions, including regular exercise, PR training, and health education, are recommended to optimize college students’ psychological health.

Objective This study investigates the relationship between emotional management ability and sleep quality in university students, examining the chain-mediating roles of physical exercise and electronic health literacy. The findings provide a theoretical and practical basis for understanding and addressing sleep problems in this population. Methods Utilizing 2022 data from the China Physical Activity and Health Longitudinal Study - College Students (CPAHLS-CS), this study investigated four applied universities–Nanjing Xiaozhuang University, Yangzhou University, Shangqiu College, and Yangzhou Polytechnic College–through stratified random sampling, ensuring a representative sample from each institution. Emotional Intelligence Scale (EIS), Pittsburgh Sleep Quality Index Scale (PSQI), Physical Activity Rating Scale (PARS-3), and Electronic Health Literacy Scale (eHEALS) were used for measurement. Descriptive statistics, correlation analyses, regression analyses, and chained mediation effects tests were performed using SPSS 26.0 and process plug-ins, controlling for confounding variables such as gender, grade, smoking, and alcohol use. Results Emotional management ability was statistically significantly and negatively correlated with sleep quality ( β = -0.051, p  < 0.001). Physical exercise and electronic health literacy acted as chain mediators between emotional management ability and sleep quality, with a total effect value of -0.042 (95% CI [-0.059, -0.025]), a direct effect value of -0.051 (95% CI [-0.070, -0.031]), and an indirect effect value of 0.009 (95% CI [-0.003, 0.019]). Emotional management ability indirectly improved sleep quality ( β = -0.020, p  < 0.001) through enhanced physical exercise ( β  = 0.430, p  < 0.001) and indirectly promoted sleep quality ( β  = 0.027, p  < 0.001) through enhanced electronic health literacy ( β  = 0.655, p  < 0.001). The chain-mediated pathway’ emotional management ability → physical exercise → electronic health literacy → sleep quality’ had an effect value of 0.0002, suggesting a small but non-negligible effect. Conclusion In several ways, emotional management ability and sleep quality are related among application-oriented university students. There’s a direct negative correlation between them, and it’s also possible that physical exercise and electronic health literacy are mediators in a chain, indirectly affecting sleep quality.

Mitochondrial dysfunction is increasingly recognized as a central contributor to the pathogenesis of cardiovascular diseases (CVDs), including heart failure, ischemic heart disease, hypertension, and cardiomyopathy. Mitochondria, known as the powerhouses of the cell, play a vital role in maintaining cardiac energy homeostasis, regulating reactive oxygen species (ROS) production and controlling cell death pathways. Dysregulated mitochondrial function results in impaired adenosine triphosphate (ATP) production, excessive ROS generation, and activation of apoptotic and necrotic pathways, collectively driving the progression of CVDs. This review provides a detailed examination of the molecular mechanisms underlying mitochondrial dysfunction in CVDs, including mutations in mitochondrial DNA (mtDNA), defects in oxidative phosphorylation (OXPHOS), and alterations in mitochondrial dynamics (fusion, fission, and mitophagy). Additionally, the role of mitochondrial dysfunction in specific cardiovascular conditions is explored, highlighting its impact on endothelial dysfunction, myocardial remodeling, and arrhythmias. Emerging therapeutic strategies targeting mitochondrial dysfunction, such as mitochondrial antioxidants, metabolic modulators, and gene therapy, are also discussed. By synthesizing recent advances in mitochondrial biology and cardiovascular research, this review aims to enhance understanding of the role of mitochondria in CVDs and identify potential therapeutic targets to improve cardiovascular outcomes.

Alzheimer’s disease (AD) impacts more than half a million people worldwide, with no cure available. The regulatory approval of three anti-amyloid monoclonal antibodies (mAbs), including aducanumab, lecanemab, and donanemab, has established immunotherapy as a therapeutic approach to modify disease progression. Its multifactorial pathology, which involves amyloid-β (Aβ) plaques, tau neurofibrillary tangles, neuroinflammation, and cerebrovascular dysfunction, limits the efficacy of single-target therapies. The restricted blood–brain barrier (BBB) penetration and amyloid-related imaging abnormalities (ARIA), together with small treatment effects, demonstrate the necessity for advanced biologic therapies. Protein engineering advancements have created bispecific antibodies that bind to pathological proteins (e.g., Aβ, tau) and BBB shuttle receptors to boost brain delivery and dual therapeutic effects. This review combines existing information about antibody-based therapy in AD by focusing on bispecific antibody formats and their preclinical and clinical development, as well as biomarker-based patient selection and upcoming combination strategies. The combination of rationally designed bispecific antibodies with fluid and imaging biomarkers could show potential for overcoming existing therapeutic challenges and delivering significant clinical advantages.

Mitochondrial dysfunction represents a pivotal characteristic of numerous neurodegenerative disorders, including Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and amyotrophic lateral sclerosis. These conditions, distinguished by unique clinical and pathological features, exhibit shared pathways leading to neuronal damage, all of which are closely associated with mitochondrial dysfunction. The high metabolic requirements of neurons make even minor mitochondrial deficiencies highly impactful, driving oxidative stress, energy deficits, and aberrant protein processing. Growing evidence from genetic, biochemical, and cellular investigations associates impaired electron transport chain activity and disrupted quality-control mechanisms, such as mitophagy, with the initial phases of disease progression. Furthermore, the overproduction of reactive oxygen species and persistent neuroinflammation can establish feedforward cycles that exacerbate neuronal deterioration. Recent clinical research has increasingly focused on interventions aimed at enhancing mitochondrial resilience—through antioxidants, small molecules that modulate the balance of mitochondrial fusion and fission, or gene-based therapeutic strategies. Concurrently, initiatives to identify dependable mitochondrial biomarkers seek to detect pathological changes prior to the manifestation of overt symptoms. By integrating the current body of knowledge, this review emphasizes the critical role of preserving mitochondrial homeostasis as a viable therapeutic approach. It also addresses the complexities of translating these findings into clinical practice and underscores the potential of innovative strategies designed to delay or potentially halt neurodegenerative processes.

Coronavirus-19 (COVID-19) caused by SARS-CoV-2 has become a global pandemic. Risk of transmission may occur during endoscopy and the goal is to prevent infection among healthcare professionals while providing essential services to patients. Asia was the first continent to have a COVID-19 outbreak, and this position statement of the Asian Pacific Society for Digestive Endoscopy shares our successful experience in maintaining safe and high-quality endoscopy practice at a time when resources are limited. Sixteen experts from key societies of digestive endoscopy in Asia were invited to develop position statements, including patient triage and risk assessment before endoscopy, resource prioritisation and allocation, regular monitoring of personal protective equipment, infection control measures, protective device training and implementation of a strategy for stepwise resumption of endoscopy services after control of the COVID-19 outbreak.

The incidence of young-onset colorectal cancer (CRC) is reported to be increasing in the Western world. There are no population-based studies assessing the trend across Asia. We performed a multinational cohort study involving four Asian countries/regions, namely Taiwan, Korea, Japan, and Hong Kong. The magnitude and direction of trend in the incidence of young-onset CRC (age < 50) were quantified using Joinpoint Regression Program to estimate average annual percentage change (AAPC). In Taiwan (1995-2014), incidence of young-onset CRC significantly increased in both men (colon cancer: 4.9-9.7 per 100,000; rectal cancer: 4.0-8.3 per 100,000) and women (colon cancer: 5.1-9.7 per 100,000; rectal cancer: 3.8-6.4 per 100,000). In Korea (1999-2014), incidence of young-onset CRC significantly increased in both men (colon cancer: 5.0-10.4 per 100,000; rectal cancer: 4.9-14.0 per 100,000) and women (colon cancer: 4.1-9.6 per 100,000; rectal cancer: 4.1-9.1 per 100,000). The most pronounced change was observed with male rectal cancer, increasing by 3.9% per year in Taiwan (AAPC + 3.9, 95% confidence interval + 3.3 to +4.5, P < 0.05) and 6.0% per year in Korea (AAPC +6.0, 95% confidence interval + 4.5 to +7.6, P < 0.05). Only a significant increase in rectal cancer was noted in Japan (male rectal cancer: 7.2-10.1 per 100,000, female rectal cancer 4.7-6.7 per 100,000) and Hong Kong (male rectal cancer: 4.4-7.0 per 100,000). Increasing trend in young-onset CRC is not limited to the Western world. This finding may have implications on screening program for CRC in these countries/regions.

Nanoparticles-based glues have recently been shown with substantial potential for hydrogel adhesion. Nevertheless, the transformative advance in hydrogel-based application places great challenges on the rapidity, robustness, and universality of achieving hydrogel adhesion, which are rarely accommodated by existing nanoparticles-based glues. Herein, we design a type of nanohesives based on the modulation of hydrogel mechanics and the surface chemical activation of nanoparticles. The nanohesives can form robust hydrogel adhesion in seconds, to the surface of arbitrary engineering solids and biological tissues without any surface pre-treatments. A representative application of hydrogel machine demonstrates the tough and compliant adhesion between dynamic tissues and sensors via nanohesives, guaranteeing accurate and stable blood flow monitoring in vivo. Combined with their biocompatibility and inherent antimicrobial properties, the nanohesives provide a promising strategy in the field of hydrogel based engineering. Achieving rapid, robust, and universal hydrogel adhesion poses challenges for nanoparticle-based glues. Here, the authors present nanohesives that can adhere to diverse surfaces without pre-treatment based on hydrogel mechanics design and interface chemistry modification.
