DNA Damage Induced by Ultrasound and Cellular Responses

Ultrasonic technologies pervade the medical field as a long established imaging modality in clinical diagnostics and, with the emergence of targeted high-intensity focused ultrasound, as a means of thermally ablating tumors. Ultrasound (US) causes multiple thermal and non-thermal effects, such as mechanical and chemical stresses, that can result in damage to the cellular membrane and nucleus, l...

Multiple phase changes induced by frustration in randomlyconnected cellular

Frustration is introduced in randomly connected totalistic cellular automata via mixing of rules leading to incompatible periods. As the respective concentration of rules is varied, these cellular automata go through 8 phases many of which with symmetries diierent from the two rules mixed in. The complex phase diagram so created is similar to those seen in frustrated systems in static equilibri...

Zeeman effect induced by intense laser light.

We analyze spectral line shapes of hydrogenlike species subjected to fields of electromagnetic waves. It is shown that the magnetic component of an electromagnetic wave may significantly influence the spectra. In particular, the Zeeman effect induced by a visible or infrared light can be experimentally observed using present-day powerful lasers. In addition, the effect may be used for diagnosti...

Ultrasound-Induced New Cellular Mechanism Involved in Drug Resistance

The acoustic effects in a biological milieu offer several scenarios for the reversal of multidrug resistance. In this study, we have observed higher sensitivity of doxorubicin-resistant uterine sarcoma MES-SA/DX5 cells to ultrasound exposure compared to its parent counterpart MES-SA cells; however, the results showed that the acoustic irradiation was genotoxic and could promote neotic division ...

Epithelial and stromal changes induced by intacs examined by three-dimensional very high-frequency digital ultrasound.

PURPOSE To examine epithelial and stromal layers by three-dimensional very high-frequency (VHF) digital ultrasound scanning before and after implantation of Intacs (intracorneal ring segments [ICRS]). METHODS Three-dimensional scanning was performed in five eyes before and 3 months after Intacs insertion. Digital signal processing techniques provided high-resolution B-scan imaging and I-scan ...
