Curcumin-Loaded Nanoparticles with Low-Intensity Focused Ultrasound-Induced Phase Transformation as Tumor-Targeted and pH-Sensitive Theranostic Nanoplatform of Ovarian Cancer

Nanoscale Research Letters, 2020
We have developed a simple and versatile nanoplatform using pH-sensitive ferritin nanocages co-loaded with the anticancer drug curcumin (Cur) and liquid fluorocarbon perfluorohexane (PFH) inside the core and conjugated tumor-targeting molecule FA outside

Selective Ablation of Cancer Cells with Low Intensity Pulsed Ultrasound [PDF]

, 2020
Ultrasound can be focused into deep tissues with millimeter precision to perform noninvasive ablative therapy for diseases such as cancer. In most cases, this ablation uses high intensity ultrasound to deposit nonselective thermal or mechanical energy at

Mathematical Analysis of Ultrafast Ultrasound Imaging [PDF]

, 2016
This paper provides a mathematical analysis of ultrafast ultrasound imaging. This newly emerging modality for biomedical imaging uses plane waves instead of focused waves in order to achieve very high frame rates.

T2-based temperature monitoring in bone marrow for MR-guided focused ultrasound. [PDF]

, 2016
BackgroundCurrent clinical protocols for MR-guided focused ultrasound (MRgFUS) treatment of osseous lesions, including painful bone metastases and osteoid osteomas, rely on measurement of the temperature change in adjacent muscle to estimate the ...

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 ...

A Surgical Perspective on Targeted Therapy of Hepatocellular Carcinoma. [PDF]

, 2015
Hepatocellular carcinoma (HCC), the second leading cause of cancer deaths worldwide, is difficult to treat and highly lethal. Since HCC is predominantly diagnosed in patients with cirrhosis, treatment planning must consider both the severity of liver ...

Noninvasive Monitoring of Tissue Temperature Changes Induced by Focused Ultrasound Exposure using Sparse Expression of Ultrasonic Radio Frequency Echo Signals

Journal of Medical Signals and Sensors
Background: Noninvasive therapies such as focused ultrasound were developed to be used for cancer therapies, vessel bleeding, and drug delivery. The main purpose of focused ultrasound therapy is to affect regions of interest (ROI) of tissues without any ...

Distinct immune signatures in directly treated and distant tumors result from TLR adjuvants and focal ablation. [PDF]

, 2018
Both adjuvants and focal ablation can alter the local innate immune system and trigger a highly effective systemic response. Our goal is to determine the impact of these treatments on directly treated and distant disease and the mechanisms for the ...

Fully automated segmentation and tracking of the intima media thickness in ultrasound video sequences of the common carotid artery [PDF]

, 2013
—The robust identification and measurement of the intima media thickness (IMT) has a high clinical relevance because it represents one of the most precise predictors used in the assessment of potential future cardiovascular events.

Potential applications of focused ultrasound for spinal cord diseases: a narrative review of preclinical studies

Brain and Spine
Focused ultrasound (FUS) technology provides unique advantages as a therapy targeting the central nervous system (CNS). We aimed to investigate and summarize the potential applications of FUS in the context of spinal cord diseases. Search strategies were
