With climate change and increasing world population, the competition for water available for crop irrigation has increased. The main methods employed to meet the existing food needs are addition of fertilizers to soil and genetic engineering of plants. However, the short-and long-term impacts of these techniques on health and environment are of major concern. The study presented here demonstrates that nonthermal plasma (NTP) treatment of water may address these challenges without the addition of chemicals. Plasma produces a wide variety of metastable radicals, predominantly reactive oxygen and reactive nitrogen species (ROS, RNS) that have been previously proven to activate plant defense responses and to accelerate growth. In this work, NTP was used to treat deionized water for irrigation of Arabidopsis thaliana plants for 7 weeks. Plasma treatment decreased overall water consumption for irrigation, simultaneously enhancing plant growth and yield. We suggest that the reactive nitrogen species (NO3-N) generated by the plasma is responsible for the increased fecundity of plants. © 2015 by Begell House, Inc.

Plasma has been shown to be effective against cancer cells both in vitro and in vivo. Several studies have documented the selectivity of plasma against cancer cells with minimal or reduced damage to normal cells. However, complete remission of cancer following plasma treatment has not been achieved yet. In the body, the immune system plays a vital role in the prevention and control of cancer. Presence of cells of the adaptive immune system in the tumor microenvironment is usually an indicator of good prognosis.[1] Since immune cell migration is a key initial step towards defense against diseases, it is important to evaluate the influence of plasma treatment on such cellular functions. Here we show that treatment with nanosecond-pulsed non-thermal dielectric barrier discharge enhances migration of macrophages in vitro. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
