BACKGROUND The stimulation of nerve or cortical tissue by magnetic induction is a relatively new tool for the non-invasive study of the brain and nervous system. Transcranial magnetic stimulation (TMS), for example, has been used for the functional mapping of the motor cortex and may have potential for treating a variety of brain disorders. METHODS AND RESULTS A new method of stimulating acti...

INTRODUCTION Ultrasound and electric stimulation are known therapies for the treatment of chronic ulcerations. Combined modulated ultrasound and electric field stimulation (CUSEFS) have never been studied as a single modality. The authors evaluate the results of CUSEFS (BRH Medical Ltd, Jerusalem, Israel) on a variety of wound types in a number of clinics. METHODS This retrospective analysis ...

objective: this study presents an efficient, cost-effective method to improve proliferation and colonization of spermatogonial stem cells (sscs) in vitro. methods: isolated sscs from neonate mice were cultured in dmem culture medium with 10% fetal bovine serum (fbs). in the first phase of the study, the temperature was controlled by low intensity pulsed ultrasound stimulation (lipus) of the pla...

BACKGROUND Current techniques of brachial plexus block are "blind," and nerve localization can be frustrating and time consuming. Previous studies on ultrasound-assisted brachial plexus blocks are mostly performed with scanning probes of 10 MHz or less. The authors tested the usefulness of a state-of-the-art, high-resolution ultrasound probe (up to 12 MHz) in identifying the brachial plexus in ...

Elastography is capable of noninvasively detecting hepatic fibrosis by imposing mechanical stress and measuring the viscoelastic response in the liver. Magnetic resonance elastography (MRE) relies on time-harmonic vibrations, while most dynamic ultrasound elastography methods employ transient stimulation methods. This study attempts to benefit from the advantages of time-harmonic tissue stimula...

biophysical profile (bpp) test is the most commonly used antenatal test of fetal well-being. purpose of this study is determining the influence of acoustic stimulation (as) on bpp testing time. about 55 pregnant women at 35 to 42 weeks who referred to department of obstetric & gynecology at university of medical sciences, tabriz, iran, were selected randomly. we used abdominal ultrasound guidan...

It has recently been shown that a few fish species, including American shad (Alosa sapidissima; Clupeiformes), are able to detect sound up to 180 kHz, an ability not found in most other fishes. Initially, it was proposed that ultrasound detection in shad involves the auditory bullae, swim bladder extensions found in all members of the Clupeiformes. However, while all clupeiformes have bullae, n...
