چکیده
Ultrasound has been a part of clinical practice since sometime back in the 1950's, and remains a popular and evidenced intervention for a range of clinical problems. Shah and Farrow (2012) provide an insight into its current clinical popularity as does the widely cited paper by Pope et al (1995). General (textbook) reviews and explanations can be found in Watson and Young (2008) and Robertson et al (2006) amongst others.

Destructive effects of therapeutic ultrasound and gold nanoparticles on a breast carcinoma tumor model in BALB/c mice
Background: Acoustic cavitation which occurs at high intensities of ultrasound waves can be fatal for tumor cells; however, it can be used to destroy cancer cells as an efficient therapeutic method. On the other hand, it is known that the existence of nanoparticles in a liquid decreases the acoustic cavitation onset threshold. Materials and Methods: In this work, the combined effects of therape...

Objective: The effect of ceftazidime on Pseudomonas aeruginosa, with or without application of 1 MHz therapeutic ultrasound, was studied. Method: An aqueous suspension of microorganisms in a sterile, sealed plate was placed in an ultrasonic tank operating at 1 MHz. Different power outputs were used. After desired time of exposure to the ultrasound, each sample was plated separately and aft...
متن کاملAn overview of therapeutic applications of ultrasound based on synergetic effects with gold nanoparticles and laser excitation
Acoustic cavitation which occurs at high intensities of ultrasound waves can be fatal for tumor cells. The existence of dissolved gases and also the presence of nanoparticles (NPs) in a liquid, irradiated by ultrasound, decrease the acoustic cavitation onset threshold and the resulting bubbles collapse. On the other hand, due to unique capabilities and optical properties of gold nanoparticles (...

متن کاملInduction of a bystander effect after therapeutic ultrasound exposure in human melanoma: In-vitro assay
Background: The induction of bystander effect via ionizing radiation has been well proven. However, few studies have investigated the bystander effect following non-ionizing radiation, such as ultrasound waves. Here, the bystander effect after different sonication times on human melanoma cell line (A375), is evaluated by assessing cell viability and apoptosis. Materials and Methods: The cells w...
