This study presents experimental data on a combined treatment of cancer cells with cold atmospheric pressure plasma (CAP) and the antitumor drug gemcitabine (GB). Our results indicate a synergistic effect of plasma and gemcitabine, which specifically hits tumor cells more effectively than healthy fibroblasts with identical genetic background.

The effect of precursor carbon double bond unsaturations on the specific plasma deposition rate (k0) and thermal properties of plasma deposited methacrylate-like films is assessed in this work. A significant increase in the plasma deposition rate with increasing number of precursor CC bonds is found. In general, two distinctive thermal characteristics are observed by DSC: a relatively low Tg and a residual reactivity in the first heating of the DSC experiment.

Design of experiments has been used to optimize the plasma conversion of CO2 into CO and oxygen in a dielectric barrier discharge reactor. The importance of different independent process parameters, especially the interactions of these parameters on the plasma conversion of CO2 has been investigated.
- Deposition of Plasma-Polymerized Polyacrylic Acid Coatings by a Non-Equilibrium Atmospheric Pressure Nanopulsed Plasma Jet

Article first published online: 28 SEP 2015 | DOI: 10.1002/ppap.201500080
An acrylic acid plasma polymerization process, for the deposition of plasma-polymerized polyacryilic acid coatings stable upon water contact with high amount of carboxyl groups, by means of a non-equilibrium atmospheric pressure nanopulsed plasma jet is reported. A thorough characterization of the chemical structure of the coatings, jointly to some insights on their morphological characteristics, is presented.
- Histological and Nuclear Medical Comparison of Inflammation After Hemostasis with Non-Thermal Plasma and Thermal Coagulation

In this paper, inflammation after hemostasis with non-thermal plasma (NTP) and thermal coagulation (TC) are compared. In comparison to TC, hemostasis by NTP resulted in an earlier conclusion of both inflammatory cell infiltration and 18F-FDG accumulation at the hemostasis site. Thus, this study indicates that hemostasis by NTP is associated with a shorter period of inflammation than TC hemostasis.
