Small Extracellular Vesicles from Neural Cells: Physiological and Pathological Roles, and Potential in Neurodegenerative Therapy

Advanced Healthcare Materials, EarlyView.
Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...

A Model of Operant Conditioning for Adaptive Obstacle Avoidance [PDF]

, 1996
We have recently introduced a self-organizing adaptive neural controller that learns to control movements of a wheeled mobile robot toward stationary or moving targets, even when the robot's kinematics arc unknown, or when they change unexpectedly during

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

Advanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Engineering Resatorvid‐Loaded Sub‐Microgels of Epigallocatechin‐3‐gallate/Hyaluronic Acid to Treat Acute Lung Injury

Advanced Healthcare Materials, EarlyView.
This study presents HAEP@Res sub‐microgels as a lung‐targeted delivery system integrating antioxidant activity with anti‐inflammatory therapy. The sub‐microgels demonstrate excellent biocompatibility, efficiently scavenge intracellular ROS, and downregulate pro‐inflammatory cytokines and genes in a Bleo‐induced ALI mouse model. These findings highlight
