Synergistic Roles of FAHD‐1 and PYC‐1 in Mitochondrial Function, Behavior, and Longevity in C. elegans

Advanced Biology, EarlyView.
FAHD‐1 and PYC‐1 catalyze opposing mitochondrial reactions that regulate oxaloacetate homeostasis in Caenorhabditis elegans. Using single and double knockouts, this study reveals that both enzymes shape locomotion, reproduction, respiration, and lifespan.

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Hydrogel dressing containing natural extracts inhibits dual-species biofilms of Staphylococcus aureus and Acinetobacter baumannii in ex vivo wound infection models

Scientific Reports
Wound infections represent a significant cause of delayed wound healing. An active wound dressing was developed by incorporating extracts of Rhodomyrtus tomentosa leaf and Quercus infectoria gall in a carboxymethyl cellulose hydrogel (RQ hydrogel).

Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

Advanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.
