Carboxymethylcellulose ameliorates high-fat diet-associated colitis through the reduction of deoxycholic acid and restoration of mitochondrial complex I in macrophages

Carboxymethylcellulose (CMC) ameliorates high-fat diet-associated colitis by suppressing *Bacteroides acidifaciens*-mediated deoxycholic acid production, which restores mitochondrial complex I function in macrophages and inhibits their M1 polarization.

Tuning siRNA packing order in lipid nanoparticles modulates oligonucleotide functional delivery

This study demonstrates that tuning lipid nanoparticle composition to favor less compact, low-order siRNA packing enhances endosomal fusion and cargo release, thereby significantly improving the functional delivery and silencing potency of siRNA therapeutics.

Distinct roles of IDR and CCD domains control PABPN1 aggregation and enable therapeutic rescue

This study elucidates how the intrinsically disordered and coiled-coil domains of PABPN1 differentially regulate its aggregation and function in oculopharyngeal muscular dystrophy, and demonstrates that a naturally occurring, non-aggregating truncated isoform (trPAB) can restore protein activity and serve as a promising therapeutic strategy for the disease.

Oxidative Stress Resistance of the Extended Longevity Phenotype of Drosophila Under Paraquat Exposure Is Heritable: Influence of Maternal Genotype on the Offspring

This study demonstrates that oxidative stress resistance, a key determinant of extended longevity in *Drosophila melanogaster*, is heritable and largely additive, with a pronounced and persistent maternal effect that enhances offspring survival, locomotor performance, and antioxidant defenses across generations.

Autistic Traits and Social-Context-Dependent Prefrontal Hemodynamic Responses: An fNIRS Gameplay Study

This study demonstrates that higher subclinical autistic traits are associated with attenuated prefrontal hemodynamic responses and reduced neural differentiation between social and non-social contexts during live competitive gameplay, suggesting that dimensional autistic variation specifically impacts brain activity during reciprocal human interaction.
