ConclusionsOur results demonstrated that ddPCR could be used in detecting BRAF V600E mutation from FNA fluid samples with higher sensitivity and accuracy than ARMS.
Introduction: The use of transcranial, low intensity focused ultrasound (FUS) is an emerging neuromodulation technology that shows promise for both therapeutic and research applications. Key technical advantages include high lateral resolution of stimulation and deep penetration depth. However, empirically observed effects in vivo are diverse, and at a fundamental level, it is unclear how FUS alters the function of neural circuits at the site of sonication.
Introduction: Focused ultrasound thalamotomy (FUS-T) is an FDA approved for the treatment of Essential Tremor (ET). We have previously reported improved safety by prospectively identifying the ventral intermediate nucleus (VIM) using tractography thus reducing the need for extensive mapping. The durability of tremor improvement with this approach is unknown. Here we report for the first time the outcomes up to two years in a cohort of 9 patients with essential tremor who underwent FUS-T as a part of the FDA continued access trial.
Introduction: Peripheral neuropathies and nerve compression syndromes due to disease, repetitive injury, accidents, and toxins affect 20 million Americans with high costs, long-lasting pain, and sub-optimal outcomes from surgery, drugs, and other therapies. Ultrasound diathermy has been used extensively in physical medicine and physical therapy to treat neuropathic pain. These ultrasound methods are unfocused, use very low power levels, and do not act to modulate the activity of inflamed nerves carrying pain information to the brain.
Introduction: MR-guided focused ultrasound (MRgFUS) in conjunction with intravenous microbubbles can induce temporary blood-brain barrier (BBB) opening. This modality is well suited for noninvasive targeted therapeutic delivery, with robust preclinical safety data.
Background: It has been confirmed that ultrasound can penetrate the skull and excite or inhibit neuronal activity in brain slices, rodents and nonhuman primates. The regulation of body temperature is one of the most critical functions of the nervous system. However, whether transcranial pulsed ultrasound can regulate body temperature in mice has not been studied. Therefore, the objective of this study was to examine the effect of ultrasound stimulation of the ventral part of the lateral preoptic nucleus (vLPO) on regulation of body temperature in mice.
Background: Epilepsy is a common neurological disorder that affects more than 50 million people worldwide. It is characterized by recurrent seizures resulting from excessive excitation or inadequate inhibition of neurons Previous studies demonstrated that low-intensity pulsed ultrasound (LIPUS) could suppress the number of epileptic signal bursts observed in electroencephalographic (EEG) recordings in rodents. However, whether ultrasound can inhibit epileptiform discharges in nonhuman primates is unclear.
Background, Motivation and Objective: As a non-invasive method, ultrasound can pass through the intact skull and activate deep brain neurons, gaining increasing attention. Fundamental mechanisms of ultrasound neuro-modulation, however, have not been elucidated clearly. The nematode Caenorhabditis elegans (C. elegans) is an excellent model organism and has been widely used in the neurobiology research. Our previous work has shown that mechanical effects of the ultrasound enable to initiate reversal behaviour and activate ASH neurons of C.
Focused transcranial ultrasound (FUS) has shown neuromodulatory effects, but less research has been performed using unfocused array transducers designed for diagnostic imaging. Here we examined whether a Philips CX50 imaging ultrasound device could modulate behavior on a task that requires inhibition.
Transcranial Ultrasound Stimulation (TUS) is an emerging neuromodulatory technique that uses ultrasonic waves to noninvasively stimulate the brain. Most experiments utilize transcranial focused ultrasound (TFUS) due to high spatial resolution and deep focal penetration. Diagnostic ultrasound (dUS), typically used in medical imaging, holds important advantages over TFUS for the purpose of neuromodulation, including well-established parameters for safety, widespread availability, and ease of use. With these features in mind, we investigated the possibility of altering cortical excitability with TUS using a diagnostic system.
