Habitual Physical Activity Preserves Energetically Constrained Mitochondrial Programs During Human Skeletal Muscle Aging

This study demonstrates that habitual physical activity selectively preserves core mitochondrial bioenergetic programs and energetic function in human skeletal muscle and other tissues by counteracting the specific, coordinated proteomic remodeling associated with aging.

Comparative Evaluation of Eye-Tracking and User Experience Across Different Designs of VR Headsets for Behavioral Research

This study compares three eye-tracking-enabled VR headsets for behavioral research and finds that the Meta Quest Pro offers superior practical suitability due to its higher data yield, better usability, and lower cybersickness, despite the HP Reverb G2 Omnicept demonstrating lower angular error in successful sessions.

Genetic Gabrd Deficiency Drives Compensatory Myelination of Inhibitory Axons to Elevate Seizure Thresholds

This study reveals that global Gabrd deficiency triggers a developmentally restricted, compensatory mechanism involving Pleiotrophin-mediated myelination of parvalbumin-positive inhibitory axons, which fortifies seizure resistance and suggests myelination enhancement as a novel therapeutic strategy for refractory epilepsy.

Small-Molecule Mimicry Intercepts PEX5 Recognition by Trypanosomal PEX14 as Revealed by Molecular Dynamics

This study utilizes molecular dynamics simulations to elucidate the structural determinants of the essential PEX5–PEX14 interaction in trypanosomes and identifies SuFEx-derived naphthoquinones as promising small-molecule inhibitors that effectively mimic the native recognition motif to disrupt glycosomal protein import.
