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

open access: yesAdvanced 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,

Membrane‐Active Peptide Protects Against Inflammation by Targeting NLRP3 Activation at the Trans‐Golgi Network

open access: yesAdvanced Science, EarlyView.
The membrane‐active peptide Pep19‐2.5 reduces harmful inflammation by blocking activation of the NLRP3 inflammasome at trans‐Golgi network membranes. By targeting key membrane interactions, Pep19‐2.5 suppresses inflammatory IL‐1β production and alleviates allergic airway inflammation in mice, leading to reduced immune cell infiltration and improved ...

Human airway xenograft models of epithelial cell regeneration

open access: yesRespiratory Research, 2000
Regeneration and restoration of the airway epithelium after mechanical, viral or bacterial injury have a determinant role in the evolution of numerous respiratory diseases such as chronic bronchitis, asthma and cystic fibrosis.

Innate Immune Responses of the Airway Epithelium

open access: yesMolecules and Cells, 2010
Barrier epithelia, especially airway epithelial cells, are persistently exposed to micro-organisms and environmental factors. To protect the host from these microbial challenges, many immune strategies have evolved. The airway epithelium participates in the critical innate immune response through the secretion of immune effectors such as mucin ...

Nanometer Layer Coating to Lactose Particles for Optimization of Dexamethasone Pulmonary Delivery

open access: yesAdvanced Science, EarlyView.
Nanometer layer coating (NLC) was investigated and its mechanism illustrated by advanced characterization techniques. The effects and application for the inhalation of dexamethasone (DEX) were demonstrated through in vitro and in vivo evaluation. This approach increased DEX bioavailability and enabled the dose to be reduced to 1/30 of the intravenous ...

Bronchoscopy Robot with Enhanced Flexibility and Stability via Multi‐Segment Variable Stiffness Catheter

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a magnetic bronchoscopy robot with a novel multi‐segment variable stiffness catheter. This catheter can not only move flexibly in the narrow bronchi but also harden according to the need to provide support. Combined with remote wireless magnetic field drive, it provides a more precise and effective solution for biopsy of deep lung ...

Role of KRAS in regulating normal human airway basal cell differentiation

open access: yesRespiratory Research, 2019
Background KRAS is a GTPase that activates pathways involved in cell growth, differentiation and survival. In normal cells, KRAS-activity is tightly controlled, but with specific mutations, the KRAS protein is persistently activated, giving cells a ...

Spectrum of Congenital Anomalies in Myhre Syndrome—Insights Into Effects Brought by Altered TGF‐β Signaling via Gain‐of‐Function Variants in SMAD4

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome is a rare genetic disorder characterized by progressive multisystem involvement. Gain‐of‐function missense heterozygous variants affecting the Ile500 residue and Arg496 residue of the SMAD4 gene are implicated in this condition.

Therapy for Myhre Syndrome: Goals, Misconceptions, and Current Agents

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre Syndrome (MYHRS, MIM #139210) is a rare, multisystem connective tissue disorder caused by recurrent heterozygous gain‐of‐function pathogenic variants in the SMAD4 gene, a key player in TGF‐β signaling and a regulator of extracellular matrix homeostasis.
