Therapeutic low-intensity red laser for herpes labialis on plasmid survival and bacterial transformation
Abstract
A low-intensity laser is used in treating herpes labialis based on the biostimulative effect, albeit the photobiological basis is not well understood. In this work experimental models based on Escherichia coli cultures and plasmids were used to evaluate effects of low-intensity red laser on DNA at fluences for treatment of herpes labialis. To this end, survival and transformation efficiency of plasmids in E. coli AB1157 (wild type), BH20 (fpg/mutM−) and BW9091 (xthA−), content of the supercoiled form of plasmid DNA, as well as nucleic acids and
