Rigid Hollow Microparticles for Enhanced Focused Ultrasound Treatment Under Optoacoustic Guidance

Advanced Science, EarlyView.
By combining focused ultrasound (FUS) and acoustically active hollow borosilicate microparticles (HBMPs), we demonstrate tunable control over interparticle dynamics and their localized thermal energy deposition. Modulation of acoustic frequency and particle concentration tailors the energy delivery, allowing adaptive, material‐based regulation of ...

Microglial Fkbp5 Impairs Post‐Stroke Vascular Integrity and Regeneration by Promoting Yap1‐Mediated Glycolysis and Oxidative Phosphorylation

Advanced Science, EarlyView.
A post‐stroke perivascular niche of microglia characterized by low expression of M2 markers and elevated glycolysis, oxidative phosphorylation (OXPHOS), and phagocytic activity is identified, which is termed stroke‐activated vascular‐associated microglia (stroke‐VAM).

NIR‐Triggered Upconversion‐Perovskite Heterostructures for Non‐Genetic, Implant‐Free Optoelectronic Neuromodulation

Advanced Science, EarlyView.
The Single‐Nanostructured Optoelectronic Vehicle for neuromodulation Activation (SNOVA) establishes a paradigm for non‐genetic, implant‐free neuromodulation. By integrating NIR‐excitable UCNPs with broadband‐absorbing perovskite QDs, SNOVA efficiently converts deeply penetrating light into localized electric fields that modulate neuronal ion dynamics ...

Dose-dependent effects of transcranial alternating current stimulation on spike timing in awake nonhuman primates

Science Advances, 2019
Transcranial alternating current stimulation increases neural spike entrainment and burstiness in the awake primate brain. Weak extracellular electric fields can influence spike timing in neural networks.

Magnetically Responsive Piezoelectric Nanocapacitors Enhance Neural Recovery Following Spinal Cord Injury via Targeted Spinal Magnetic Stimulation

Advanced Science, EarlyView.
This study presents a novel “in vivo–in vitro” therapeutic strategy for spinal cord injury by leveraging magnetically responsive piezoelectric nanomaterials. These nanomaterials enable targeted delivery of localized electrical stimulation at the injury site through noninvasive external magnetic actuation, thereby promoting axonal regeneration and ...

Efficacy and Safety of Transcranial Direct Current Stimulation for Treating Negative Symptoms in Schizophrenia: A Randomized Clinical Trial.

JAMA psychiatry, 2020
Importance Negative symptoms represent a substantial burden in schizophrenia. Although preliminary studies have suggested that transcranial direct current stimulation (tDCS) is effective for some clusters of symptoms, the clinical benefits for negative ...

Data‐Driven Feedback Identifies Focused Ultrasound Exposure Regimens for Improved Nanotheranostic Targeting of the Brain

Advanced Science, EarlyView.
ABSTRACT The blood‐brain barrier (BBB) renders the delivery of nanomedicine in the brain ineffective and the detection of circulating disease‐related DNA from the brain unreliable. Here, we demonstrate that microbubble‐enhanced focused ultrasound (MB‐FUS) mediated BBB opening, supported by large‐data models predict sonication regimens for safe and ...
