Determinants of fractal motor activity regulation: insights from a large community-dwelling multi-ethnic population

This study analyzes a large multi-ethnic cohort to demonstrate that fractal motor activity regulation is significantly influenced by age, sex, physical activity levels, and race/ethnicity, with distinct patterns observed across different demographic groups that could enhance early Alzheimer's disease detection.

Chuangyu Liquid promotes wound healing by modulating an AKT1‑centered regulatory network based on network pharmacology and molecular docking

This study demonstrates that Chuangyu Liquid promotes cutaneous wound healing by modulating an AKT1-centered regulatory network, a mechanism identified through network pharmacology, molecular docking, and validated by in vivo experiments showing increased Akt1 mRNA and AKT protein levels.

The wheat immune receptor Yr28 recognises a highly conserved effector from stripe rust

This study identifies the highly conserved effector AvrYr28-01 as the target of the wheat immune receptor Yr28, explaining its broad-spectrum and potentially durable resistance against stripe rust despite the presence of unrecognized paralogous variants and age-dependent resistance suppression.

Optimal Control of SEIVZ Epidemic Model with Holling IV Incidence and Information Intervention

This paper proposes an optimal control strategy for an SEIVZ epidemic model incorporating Holling-IV incidence and information intervention, demonstrating that while the disease-free equilibrium is stable when R0≤1R_0 \le 1 with a backward bifurcation at R0=1R_0 = 1, the combined application of information and treatment controls effectively mitigates disease spread while minimizing associated costs.

Spectral characterization of different indoor lighting systems and electronic devices with backlit screens and analysis of their potential to suppress melatonin levels in humans

This study characterizes the spectral irradiance of various indoor lighting systems and backlit electronic devices, revealing that their blue-rich emissions can suppress human melatonin levels significantly within minutes to hours, thereby posing a substantial risk to circadian rhythms in typical professional and educational environments.

From Evidence to Action: Physical Activity, Attention, and Cognitive Aging—A Systematic Review and Future Directions

This systematic review of 29 studies involving adults aged 60 and older demonstrates that physical activity, particularly aerobic, resistance, and open-skill exercises, significantly enhances attentional functions and supports broader cognitive health in aging populations, offering a scalable strategy to mitigate cognitive decline.
