Delivery of ultrashort pulses of electrical energy serves a promising nonthermal, nonscarring process of inducing controlled cell death in common skin lesions.
To Detect Early Cancer, Bioelectric Signals can be Used
At Tufts University School of Arts and Sciences, biologists have discovered a bioelectric signal that can identify cells that are likely to develop into tumors.

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.
Risk of Skin Cancer High Among Patients Who Complain of Skin Lesions Being Painful or Itchy
A new study reveals that doctors who ask patients if a suspicious skin lesion is painful or itchy can make better decisions on whether the spot is likely to be cancerous.

Treating Precancerous Skin Lesions with Laser Removal may be Beneficial
Carbon dioxide laser ablation (removal) may serve as an alternate in treating common precancerous skin lesion called lentigo maligna in case surgery or radiation therapy is not viable, states report.
