Lung‐Penetrating Biomimetic Extracellular Vesicle Spherical Nucleic Acids for Pulmonary Fibrosis Therapy Through ROS Scavenging and Anti‐Inflammatory Effects

Aggregate, EarlyView.
This work describes a biomimetic extracellular vesicle‐spherical nucleic acid (BEV‐SNA) platform for idiopathic pulmonary fibrosis (IPF) therapy. BEV‐SNA is composed of mechanically extruded BEVs from primary MSCs and cholesterol‐modified ssDNA that are assembled through hydrophobic interactions.

Analysis of the Navigation of Magnetic Microrobots through Cerebral Bifurcations for Targeted Drug Delivery

Advanced Intelligent Systems, EarlyView.
The motion of magnetic microrobots through cerebral bifurcations depends on various parameters such as the microrobots size, the blood velocity, and the imposed magnetic field gradients, among others. This work presents an in‐depth analysis of the effects of these parameters and equations predicting the required magnetic gradients based on the ...

Mesenchymal stromal cells reduce inflammation and improve lung function in a mouse model of cystic fibrosis lung disease

Scientific Reports
Mesenchymal stromal cells (MSCs) are multipotent adult stem cells which possess immunomodulatory and repair capabilities. In this study, we investigated whether MSC therapy could modulate inflammation and lung damage in the lungs of Scnn1b-transgenic ...

Mast-cell infiltration of airway smooth muscle in asthma.

New England Journal of Medicine, 2002
BACKGROUND Asthma and eosinophilic bronchitis are characterized by similar inflammatory infiltrates in the submucosa of the lower airway. However, eosinophilic bronchitis differs from asthma in that there is no variable airflow obstruction or airway ...

A Magnetically Transformable Twisting Millirobot for Cargo Delivery at Low Reynolds Number

Advanced Intelligent Systems, EarlyView.
Herein, a soft millirobot, TwistBot, that transforms from a flat shape to a helical shape to propel in fluids at low Reynolds number is reported. Its geometry is optimized by numerical simulation and validated by experiments to effectively propel and deliver solid cargos.

PM2.5 Induced Nasal Mucosal Barrier Dysfunction and Epithelial–Mesenchymal Transition to Promote Chronic Rhinosinusitis Through IL4I1-AhR Signaling Pathway

Toxics
Environmental pollutants like PM2.5 contribute to chronic rhinosinusitis (CRS). The aryl hydrocarbon receptor (AhR), a contaminant sensor linked to tryptophan metabolites, is regulated by IL4I.

Design, Modeling, and Control of a Soft Robotic Diaphragm‐Assist Device in a Respiratory Simulator

Advanced Intelligent Systems, EarlyView.
A soft robotic diaphragm‐assist device using fabric‐based pneumatic actuators with a 2‐step control system to optimize synchronization and support is introduced. This system can detect the initiation of breathing to trigger assistance and regulate pressures to provide the correct level of inhalation augmentation. Validation and testing are completed on
