Bioelectric cell properties have been revealed as powerful targets for modulating stem cell function, regenerative response, developmental patterning, and tumor reprograming. Spatio-temporal distributions of endogenous resting potential, ion flows, and electric fields are influenced not only by the genome and external signals but also by their own intrinsic dynamics. Ion channels and electrical...

Microbes have been able to persist in water distribution systems through the development of multicellular communities known as biofilms. This study evaluated the usefulness of the bioelectric effect for the elimination of water distribution system biofilms from annular reactors. The bioelectric effect did not have any bactericidal action either alone or when coupled with free chlorine.

The submitted paper is a preliminary trial of comparison between two illnesses: depression (or affective disorders) and epilepsy. Despite specific phenotypical differences determining the diagnostic and classification belongings there are a lot of similarities or common elements between both groups of disorders. Special stress was put on the bioelectrical background or phenomena accompanying ep...

We deal with the efficient solution of the so-called bidomain system which is possibly the most complete model for the cardiac bioelectric activity. We study the performance of a non-symmetric structured algebraic multigrid preconditioner on the formulation generally used of the bidomain model, i.e. the one characterized by a parabolic equation coupled with an elliptic one. Our numerical result...

OBJECTIVES Permanent injury to the cranial nerves can often result in a substantial reduction in quality of life. Novel and innovative interventions can help restore form and function in nerve paralysis, with bioelectric interfaces among the more promising of these approaches. The foreign body response is an important consideration for any bioelectric device as it influences the function and ef...

Somatosensory evoked potentials (SEPs) were obtained from 15 rats that were inflected with graded injury using the NYU Impactor. SEPs, in response to stimuli to the nerves in the limbs, were recorded from the cranium. Spectral coherence was used to analyze these signals. Results obtained from the investigation show that this technique is capable of providing a quantitative measure of spinal cor...

Many facets of bioelectric activity have been investigated using both animal and human models. The scope of bioelectric research is wide, ranging from alterations in skin potentials in response to psychological stress and sleep, through to changes in cell membrane potentials in response to external electrical stimulation. In an attempt to establish some order to the breadth of research, an orga...

For maintaining a steady food supply, the trend has been toward developing factorylike production methods in Japan. To date, there has been no indicator that can predict the growth status of crops. We have accordingly focused on the bioelectric potential inside the plant, which could be an indicator of plant growth. However, a few research studies have been conducted on its role in determining ...
