BACKGROUND & OBJECTIVE Postmenopausal osteoporosis leads to a significant decline in bone mass. That complicates the treatment outcome. The objective of the present study was to find out the effects of pulsed modulated low level electric field capacitively coupled on bone histology of induced osteoporotic rats, for screening the potential therapy for osteoporosis. METHODS Osteopororosis was i...

Electric fields of repetitively pulsed nanosecond discharges have been measured from electric-field induced Raman scattering by hydrogen molecules. Especially the temporal evolution of the electric field spatial distribution was recorded. With a high-speed optical emission intensity analysis, it has been found that most ionization events take place within a very short period during an ionizatio...

The effect of the application of pulsed electric fields to potato tissue on the diffusion of the fluorescent dye FM1-43 through the cell wall was studied. Potato tissue was subjected to field strengths ranging from 30 to 500 V/cm, with one 1 ms rectangular pulse, before application of FM1-43 and microscopic examination. Our results show a slower diffusion of FM1-43 in the electropulsed tissue w...

We studied the development of surface instabilities leading to the generation of multielectron bubbles (MEBs) in superfluid helium upon the application of a pulsed electric field. We found the statistical distribution of the charge of individual instabilities to be strongly dependent on the duration of the electric field pulse. The rate and probability of generation of these instabilities in re...

The detection and identification of behaviorally relevant signals in the presence of competing signals in the environment is a major challenge of animal sensory systems. In weakly electric fish such as Eigenmannia virescens, the interactions between the autogenous electric field and the electric fields of nearby conspecifics can have profound effects on the perception of other behaviorally rele...

Degenerative skin diseases affect one third of individuals over the age of sixty. Current therapies use various physical and chemical methods to rejuvenate skin; but since the therapies affect many tissue components including cells and extracellular matrix, they may also induce significant side effects, such as scarring. Here we report on a new, non-invasive, non-thermal technique to rejuvenate...

The nature of non-exponential kinetics in microbial cells inactivation by pulsed electric fields (PEF) is discussed. It was demonstrated that possible mechanism of non-exponential kinetics can be related to orientational disorder in suspension of microbial cells of anisotropic form. A numerical studies of spheroidal cell suspensions was carried out. The most pronounced deviations from the expon...
