Effects of Low Intensity Focused Ultrasound on Liposomes Containing Channel proteins [PDF]

Scientific Reports, 2018
AbstractThe ability to reversibly and non-invasively modulate region-specific brain activity in vivo suggests Low Intensity Focused Ultrasound (LIFU) as potential therapeutics for neurological dysfunctions such as epilepsy and Parkinson’s disease. While in vivo studies provide evidence of the bioeffects of LIFU on neuronal activity, they merely hint at

Low‐Intensity Focused Ultrasound‐Responsive Ferrite‐Encapsulated Nanoparticles for Atherosclerotic Plaque Neovascularization Theranostics

Advanced Science, 2021
Pathological angiogenesis is a crucial factor that causes atherosclerotic plaque rupture. Sinoporphyrin sodium‐mediated sonodynamic therapy (DVDMS‐SDT) induces regression of plaque neovascularization in humans without causing obvious side effects ...

Autonomic modulation by low-intensity focused ultrasound stimulation of the vagus nerve

Journal of Neural Engineering, 2022
Abstract Objective. Our previous study has shown that low-intensity focused ultrasound stimulation (FUS) of the vagus nerve could modulate blood pressure (BP), but its underlying mechanisms remain unclear. We hypothesized that low-intensity FUS of the vagus nerve would regulate autonomic function and thus BP. Approach.

Sonication of the anterior thalamus with MRI-Guided transcranial focused ultrasound (tFUS) alters pain thresholds in healthy adults: A double-blind, sham-controlled study

Brain Stimulation, 2020
Background: Transcranial focused ultrasound (tFUS) is a noninvasive brain stimulation method that may modulate deep brain structures. This study investigates whether sonication of the right anterior thalamus would modulate thermal pain thresholds in ...

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
