The Effects of Low Intensity Ultrasound on Chondrogenic Differentiation of Rabbit Mesenchymal Stem Cells In Vivo
In this study of using a low-intensity ultrasound (LIUS), investigated the effects of LIUS on chondrogenic differentiation of bone marrow-derived mesenchymal stem cells (BM-MSCs). The hypothesis is that LIUS may be a non-invasively effective stimulant to a biological system in vivo by turning on …

Advancing Transcranial Focused Ultrasound for Noninvasive Neuromodulation of Human Cortex
Ultrasound waves are mechanical undulations above the threshold for human hearing, and have been used widely in both the human body and brain for diagnostic and therapeutic purposes. Ultrasound can be controlled using specially designed transducers into a focus of a few millimeters in diameter. Low …

Analyses and predictions of ultrasound interactions with model biomembrane systems via two-state transition model
Low intensity ultrasound (approximately 10$\sp{-6}$ W/cm$\sp2$) in the frequency range of 0.5 MHz to 5.0 MHz was employed to investigate biomembrane structural relaxation kinetics via absorption and velocity dispersion spectroscopy. The multilamellar vesicles utilized in this investigation were …

Transcranial Administration of Nano Pulse Laser Therapy for Blast Induced Neurotrauma
… light and therapeutic optoacoustically generated low intensity ultrasound waves, as a prophylactic for high-risk populations. Our previous research has shown a reduction in neuronal death and microglial activation in a rat model of focal TBI. Our current work aims to determine the viability of …

Ultrasound-enhanced Fibrinolysis Pro-fibrinolytic and Non-beneficial Effects Of Ultrasound Exposure
… in ischemic organs, during exposure to pulsed ultrasound. This was accomplished by studies of the effects of different intensities of pulsed ultrasound exposure on the fibrinolytic properties of streptokinase and reteplase. Measurements were performed both following pre-exposure of the drugs …

Diverse roles of cyclooxygenase in the central nervous system and the periphery
… with cyclic feedback. In this study, using low intensity ultrasound (LIUS), I demonstrated relevance of COX-2 to arthritis resolution. Complete Freund’s adjuvant (CFA)-induced edema and synovial membrane hyperplasia in the ipsilateral joint were diminished by LIUS. The inflammatory …

Einfluss von niederenergetischem gepulsten Ultraschall auf das Proliferations- und Differenzierungsverhalten osteoblastärer Zellen in vitro
Niederenergetischer gepulster Ultraschall wird seit mehreren Jahren erfolgreich zur Therapie von verzögert heilenden Frakturen und Pseudarthrosen eingesetzt. Die Wirksamkeit wurde anhand verschiedener klinischer Studien demonstriert, die genauen Wirkmechanismen sind weniger gut verstanden. Ziel …

Low-Intensity Ultrasonic Neuromodulation of the Rat Hippocampus
… to the brain. </p> <p>Transcranial focused ultrasound stimulation (tFUS) possesses many of the characteristics desirable from a neuromodulation approach: non-invasiveness, a spatial resolution in the order of millimeters, the ability to penetrate deep brain regions even through a large …
