Bioelectric Stimulation may Help Clear Skin Lesions

Nano-pulse stimulation (NPS) therapy can help in the treatment or death of common skin lesions, reports a new study. The findings of the study are published in the journal Bioelectricity. NPS specifically targets cells, generating nanometer wide pores that allow small ions to enter to alter the flow of sodium, potassium, and calcium ions in and out of the cells. It can induce cell death in epidermal or dermal lesions, but as it does not affect the dermal collagen, it does not cause scarring.

Dr. Nuccitelli discusses the characteristics of NPS, its effects on normal skin, on epidermal lesions such as seborrheic keratosis, on dermal lesions, and on warts caused by human papillomavirus.

Also of interest in this special issue is the article entitled "Preventing Ethanol-Induced Brain and Eye Morphology Defects Using Optogenetics") by Vaibhav Pai, Tufts University, Medford, MA and Dany Spencer Adams, Tufts University and Ion Diagnostics, Watertown, MA. Exposure of a fetus to alcohol can lead to defects in the brain and eye morphology as part of fetal alcohol spectrum disorder (FASD). This is also true in the developing tadpole. Pai and Adams used this model system to test the use of optogenetics - light-induced energy - to regulate ion channel function and ion fluxes and to rescue tadpoles from the effects of alcohol.

Using controlled membrane voltage modulation, the researchers were able to rescue the ethanol-induced brain and eye defects in the tadpoles. The hyperpolarization effect was required for the full duration of ethanol exposure. Furthermore, the rescue effect acted at a distance, suggesting that bioelectric modulation to treat ethanol-induced brain and eye defects in human embryos might be possible using existing ion channel drugs.
