Ultrasound and DNA repair

[TheAlkemist]

Is there any SCIENTIFIC evidence of the effect of ultrasound on chemical repair of DNA? As in, is there peer-reviewed research in this?

Thanks.

This atricle shows that a chemotherapy-resistant ovarian cancer cell line ( because of DNA repair) becomes less resistant on exposure to ultrasound.

I couldn't read the whole article, just the abstract, but it doesn't make any sense. Ultrasound (MHz) has wavelengths in the millimeter range- how can targeted subcellular damage occur?

The abstract also did not mention the incident energy level, but I suspect it's much lower than occurs with UV damage.

Thanks for the link Jim. I can't access the full article, but if you can, could you address Andy's question? I'm curious.
Thanks :)

The abstract also did not mention the incident energy level, but I suspect it's much lower than occurs with UV damage. According to the introduction the ultrasound treatment leads to increased intracellular drug levels, I haven't read the study so I can't comment on the validity.
