AB  - Non-thermal Plasmas (NTP), formed at atmospheric pressure, produce rich gas phase chemistry of Reactive Oxygen and Nitrogen Species (RONS). In a contact with a liquid target, NTPs induce production of different long-lived RONS species inside the liquid. NTPs can be employed for creation of plasma activated water (PAW) or for destruction of pollutants dissolved in water. In recent years both aspects are being developed as parts of a new field of plasma agricultural applications. The way to tailor the RONS concentrations is by adjusting of the plasma chemistry in the gas phase, the type of water and sample vessel properties. We will present results of plasma treatments of distilled and tap water using an atmospheric pressure plasma jet with pin electrode operating with addition of noble gas (He, Ar). The idea was to feature comparison of PAW properties obtained with different plasma system parameters. Produced PAW was used for treatments of different seeds and plants with an attention on linking the plasma properties with effects on treated plant material. On the other hand, the multi-pin jet was used for decontamination of water polluted by organic dyes and pharmaceuticals. This plasma source was designed based on a single-pin unit and obtained results can provide an insight into scaling up the plasma reactivity which is a necessary step for any agricultural application. We also tested variation in the efficiency of the plasma decontamination by adding recirculation of the contaminated sample. The effective treatment surface parameter proved to be significant for regulation of the decontamination level.

AB  - A breakdown in homeostasis of redox-active metals represents an important factor for neurodegeneration. We have used EPR spectroscopy and BMPO spin-trap to investigate the catalytic properties and ligand modulation of redox activity of copper and iron in human cerebrospinal fluid (CSF). In contrast to iron, copper supplementation provoked a statistically significant increase in hydroxyl free radical generation in CSF treated with H(2)O(2). However, in a binary copper/iron containing Fenton system, iron catalytically activated copper. The chelator EDTA, which represents a model of physiological metal ligands, completely prevented copper's redox activity in CSF, while iron chelation led to a significant increase in hydroxyl radical generation, indicating that copper and iron do not only have diverse catalytic properties in the CSF but also that their redox activities are differently modulated by ligands. The application of DDC reduced hydroxyl radical generation in the CSF containing catalytically active metals (free Cu(2+) or Fe(3+)-EDTA complex). We conclude that chelators, such as DDC, are capable of preventing the pro-oxidative activity of both metals and may be suitable for reducing hydroxyl radical formation in certain pathophysiological settings.
