Toward Wireless Implantable Robotic Systems Driven by Magnetic Field for Personalized Therapy

Advanced Robotics Research, EarlyView.
Robotic materials are playing an increasingly vital role in enabling sensing and actuation at small scales. This perspective highlights recent advances in magnetic materials and magnetically actuated devices for wireless sensing, actuation, and energy harvesting toward implantable robotic systems for closed‐loop therapy.

Unexpected cause of dyspnea: A case of pleomorphic adenoma in the trachea

Radiology Case Reports
Pleomorphic adenoma (PA) is the most common benign histological form of salivary gland tumors, particularly in the parotid gland, primarily affecting women between the ages of 40 and 60. However, its occurrence in the trachea is very rare.

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia

Advanced Science, EarlyView.
Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.

PVC Nanoplastics Exposure Exacerbates Asthma through R‐Loop Accumulation and Subsequent STING Activation in Macrophages

Advanced Science, EarlyView.
Polyvinyl chloride (PVC) nanoplastics (NPs) are shown to aggravate allergic airway inflammation in asthma by triggering R‐loop accumulation and activating the cGAS‐STING pathway in macrophages. This study reveals a novel immunotoxic mechanism linking environmental plastic exposure to asthma pathogenesis and highlights potential molecular targets for ...

One-dimensional modelling of pulse wave propagation in human airway bifurcations in space-time variables [PDF]

, 2009
Airflow in the respiratory system is complicated as it goes through various regions with different geometries and mechanical properties. Three-dimensional (3-D) simulations are typically limited to local areas of the system because of their high ...

Cationic Peptoids for Systemic In Vivo Cartilage‐Targeting

Advanced Science, EarlyView.
Systemically‐dosed Cy5‐labeled cationic peptoid probe (NlysO)7 (yellow) binds to the cartilage's glycosaminoglycan content in vivo across the entire body of a neonatal mouse imaged by light sheet fluorescence microscopy, revealing fluorescence uptake in generic cartilage as well as the developing and ossifying bones.

Tackling Allergic Airway Inflammation with Organic Sheet‐Like Nanoplatforms by Targeted Elimination of Epithelial Small Extracellular Vesicles

Advanced Science, EarlyView.
In this work, “inorganic‐free” nanosheets, named PNSE are developed using template‐based synthesis technology. The functionalized organic nanosheets exhibit low cytotoxicity, mild protein adsorption, and potent binding efficacy to epithelial sEVs.
