Multiscale Coupling From Mastication to Retronasal Aroma Perception: The PG‐DTCFN Model and Multiphysics Simulation

Advanced Science, EarlyView.
Using grilled lamb skewers as a model system, this work builds a multiscale coupling framework from oral processing to retronasal aroma perception, reveals dual‐kinetic release patterns and Electroencephalogram‐characterized central encoding features, and proposes an interpretable physics‐guided deep learning model validated by multiphysics simulation,

QRICH1 Disrupts Endoplasmic Reticulum Homeostasis and Amplifies NF‐κB Signaling in Periodontal Ligament Stem Cells to Exacerbate Diabetic Periodontitis

Advanced Science, EarlyView.
QRICH1 has been established as a key factor contributing to impaired osteogenic potential and accelerated apoptosis of PDLSCs in diabetic periodontitis. QRICH1 not only significantly enhances UPR‐associated apoptotic signaling but also amplifies NF‐κB‐mediated inflammatory responses. Its inhibition restores osteogenic capacity and reduces alveolar bone
