Prophylaxis of adhesions with low frequency sound.
Despite a multitude of ingenious ideas, a review of the literature has revealed no consistently acceptable results concerning adhesion prophylaxis. While pharmacologic avenues are far from exhausted, presently, there is no acceptable regimen. A double blind experimental study was performed with 130 Sprague-Dawley rats to determine the effect of high intensity low frequency sound on postoperativ...
متن کاملLow-Frequency Sound Propagation in Lipid Membranes
In the recent years, we have shown that cylindrical biological membranes such as nerve axons under physiological conditions are able to support stable electromechanical pulses called solitons. These pulses sharemany similarities with the nervous impulse, for example, thepropagationvelocityaswell as themeasured reversibleheatproductionandchanges in thickness and length that cannot be explained w...
متن کاملLow frequency sound propagation in activated carbon.
Activated carbon can adsorb and desorb gas molecules onto and off its surface. Research has examined whether this sorption affects low frequency sound waves, with pressures typical of audible sound, interacting with granular activated carbon. Impedance tube measurements were undertaken examining the resonant frequencies of Helmholtz resonators with different backing materials. It was found that...

متن کاملUltrastructural Damage of Loligo vulgaris and Illex coindetii statocysts after Low Frequency Sound Exposure
There is a considerable lack of information concerning marine invertebrate sensitivity to sound exposure. However, recent findings on cuttlefish and octopi showed that exposure to artificial noise had a direct consequence on the functionality and physiology of the statocysts, sensory organs, which are responsible for their equilibrium and movements in the water column. Owing to a lack of availa...
