Integrated Proteomic and Phosphoproteomic Profiling Reveals Distinct Disease- and Age-Related Molecular Alterations in the Retina and Hippocampus of APP/PS1/MAPT Mice

This study utilizes synchronized proteomic and phosphoproteomic profiling of APP/PS1/MAPT mice to demonstrate that the retina exhibits earlier and broader Alzheimer's-related molecular alterations than the hippocampus, revealing distinct tissue-specific pathways and shared dysregulated molecules that support the retina as a noninvasive window into early brain pathology.

A novel de novo DNM1L mutation linked to mitochondrial fission dysfunction in a pediatric patient with epileptic encephalopathy and refractory seizures

This study characterizes a novel de novo DNM1L mutation (p.Arg365Gly) in a pediatric patient with epileptic encephalopathy, demonstrating that the variant disrupts DRP1 oligomerization, leading to defective mitochondrial fission, widespread neurodegeneration, and refractory seizures.

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.
