Evaluation of the effectiveness of kINPen Med plasma jet and bioactive agent therapy in a rat model of wound healing.

Chronic nonhealing wounds, particularly those complicated by multidrug resistant infections, represent a major health and economic challenge. Plasma treatment promotes wound repair due to its antimicrobial, angiogenic, and cell modulating properties. This study investigated the efficacy of the kINPen Med system in promoting healing and assessed if efficacy was enhanced by adding collagen or hyaluronic acid (HA).

Evaluation of the sensitivity of bacterial and yeast cells to cold atmospheric plasma jet treatments.

The focus of this research was first to determine the influence of the atmospheric plasma drive frequency on the generation of atomic oxygen species and its correlation with the reduction of bacterial load after treatment in vitro. The treatments were carried out using a helium-plasma jet source called PlasmaStream™. The susceptibility of multiple microbial cell lines was investigated in order to compare the response of gram-positive and gram-negative bacteria, as well as a yeast cell line to the atmospheric plasma treatment.
