Selenium reduces high energy shock wave-induced renal injury in rats

Urological Research, 2002
Using an in vitro model with Madin-Darby canine kidney (MDCK) cells, we showed that shock wave-induced renal injury could be ameliorated by selenium. We examined the influence of selenium, a free radical scavenger, in shock wave-induced tubular cell injury in vivo. Male rats were randomly assigned to three groups: 1 control (n= 18), 2 selenium (n = 18),

Effects of High Energy Shock Wave Exposure on Renal Function during Extracorporeal Shock Wave Lithotripsy for Kidney Stones

European Urology, 1990
In order to study the effects of high energy shock wave exposure on the kidney in extracorporeal shock wave lithotripsy (ESWL) using Dornier HM3, renal hemodynamics and renal function before and after ESWL were analyzed by 99mTc-DTPA renoscintigraphy.

Application of High Energy Shock Waves to Single Cells

1989
Extracorporeal shock wave lithotripsy has been in clinical use since 1980 with several hundred thousand patients treated to date. Striking complications, like perirenal hematomas, are rare with a range of approximately 0.5%–1.5%. High dose applications in pigs and dogs have shown devastating effects on renal parenchyma with intrarenal hemorrhage and ...

Transverse shock wave demagnetization of Nd2Fe14B high-energy hard ferromagnetics

Journal of Applied Physics, 2002
The action of transverse shock waves (the shock wave propagates across the magnetization vector M) on the magnetic phase state of a Nd2Fe14B high-energy hard ferromagnetic was investigated experimentally. The design of the ferromagnetic sample, which was made as a hollow cylinder, has made it possible to dramatically reduce the amount of the explosive ...

High-energy extracoporal shock wave therapy in plantar calcaneal spur

Der Unfallchirurg, 1998
Extracorporal shock wave application (ESWA) has been used in the treatment of stones located in kidneys, bile, pancreas and the glandula parotis. In the last 2 years several studies have shown the benefit of the ESWA on the treatment of soft tissue disorders.

Effect of High-Energy Shock Waves on Bony Tissue

1989
The indication for extracorporeal shock-wave lithotripsy (ESWL) in the treatment of lumbar and distal ureteral stones is well established. Ureteral calculi projecting onto the bony structures of the pelvis are not amenable to ESWL. Treatment options would include shock-wave treatment with the patient in a prone position where shock waves would pass ...

High energy laser beam steering with periodic shock waves

SPIE Proceedings, 2010
Atmospheric density gradients bend light as can be seen with naturally occurring mirages. Shock waves also produce density changes that bend or refract light. While a single shock front from a supersonic projectile refracts light only on the order of hundreds of arcseconds, theoretical results indicate that beam deflections of thirty or more degrees ...

Shock-wave production of nanoparticles during high-energy ion sputtering

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2003
Abstract Several previous studies have shown that the size distributions of smaller nanoparticles (n⩽40 where n is the number of atoms in a given cluster) generated by ion sputtering obey an inverse power law, with an exponent varying between −8 and −4, dependent upon the total sputtering yield.

High Energy Shock Waves (HESW) Enhance Paclitaxel Cytotoxicity in MCF-7 Cells

Breast Cancer Research and Treatment, 2003
High energy shock waves (HESW) produced by a piezoelectric generator were studied for their effect on human breast cancer cell (MCF-7) viability and sensitivity to paclitaxel. A dose-dependent impairment of cell viability was observed after HESW treatment (250-2000 shock waves, rate = 4/s, energy flux density = 0.25 mJ/mm2). Single treatment with shock

Reduction of high-energy shock-wave-induced renal tubular injury by selenium

Urological Research, 1999
In shock-wave-induced renal injury cavitation-generated free radicals play an important role. Using an in vitro model with Madin-Darby canine kidney (MDCK) cells, we investigated the influence of selenium, a free radical scavenger, in shock-wave-induced tubular cell injury. Suspensions of MDCK cells (33 x 10(6) cells/ml) were placed in small containers
