Quantifying eradication thresholds for free-ranging dog populations using population viability analysis

This study utilizes population viability analysis to demonstrate that eradicating a free-ranging dog population in Japan requires the sustained annual capture of 45 adult dogs, as adult survival is the primary driver of population growth and must be targeted alongside the reduction of anthropogenic food resources.

Motor Performance and Field Based Physical Fitness Correlates of 505 Change of Direction Performance in 9 to 10 Year Old Children: An Exploratory Cross Sectional Study

This exploratory cross-sectional study of 98 children aged 9 to 10 found that 20 m sprint time was the most consistent predictor of 505 change of direction performance, with back leg strength further explaining variance in boys and visual reaction time in girls, though the resulting models require further validation before clinical or individual use.

Effect of Physical Fitness on Body Mass Index through Artificial Intelligence in South Chinese College Students from 2013 to 2025

This study analyzes data from over 83,000 Chinese college students from 2013 to 2025 to demonstrate that physical fitness indicators are strongly associated with Body Mass Index and that an XGBoost machine learning model can effectively predict BMI, with pull-ups, vital capacity, and long-distance running identified as key predictive features.

Uniparental Disomy Reveals Hidden Genetic Causes of Congenital Heart Disease

By developing the TrioMix-UPD framework and applying it to 3,740 congenital heart disease trios, researchers revealed that uniparental disomy is a significantly enriched and underrecognized genetic cause of the disease, uncovering novel pathogenic variants and candidate genes while linking the condition to meiotic segregation defects and imprinting dysregulation.

Distinct Gut–Liver Adaptations to Dihydromyricetin and Silybin in Middle-aged Mice with Alcohol-associated Liver Injury

This study demonstrates that while both Dihydromyricetin and Silybin partially protect middle-aged mice from alcohol-associated liver injury, they achieve this through distinct gut–liver axis adaptations involving divergent metabolic, epithelial, and microbial remodeling mechanisms, thereby highlighting the critical need for age-stratified intervention strategies.

Influence of Pipe Material on Biofilm Susceptibility to Disinfection in Hospital Greywater Systems

This study demonstrates that while a sustained-action disinfectant effectively reduces bacterial viability in hospital greywater systems, its antibacterial performance varies significantly by pipe material, with rigid PVC showing the greatest efficacy and flexible PVC exhibiting the highest bacterial persistence and residual biofilm structures.

Anthropogenic disturbance shapes plant-herbivore network structure in Brazilian savannas: contrasting holometabolous and hemimetabolous insects

This study reveals that anthropogenic disturbance interacts with insect developmental modes to shape plant-herbivore network structure in Brazilian savannas, where holometabolous insects exhibit high specialization and urban-driven functional decoupling, while hemimetabolous insects maintain modular, low-connectance networks with reduced specialization in urban areas.

Loss of Fragile X Protein Impacts α-Synuclein Homeostasis via Insulin-Degrading Enzyme in Parkinson’s Disease

This study reveals that the loss of fragile X mental retardation protein (FMRP) in Parkinson's disease leads to upregulation of insulin-degrading enzyme (IDE), which normally suppresses α-synuclein aggregation, thereby identifying a novel FMRP-IDE axis that modulates early pathogenic events in Parkinson's disease.
