Redox-active iron generates reactive oxygen species that can cause oxidative organ dysfunction. Thus, the anti-oxidative systems in the body and certain dietary antioxidants, such as anthocyanins, are needed to control oxidative stress. We aimed to investigate the effects of dielectric barrier discharge (DBD) plasma technology in the preparation of Riceberry™ rice flour (PRBF) on iron-induced oxidative stress in mice. PRBF using plasma technology was rich in anthocyanins, mainly cyanidine-3-glucoside and peonidine-3-glucoside. PRBF (5 mg AE/mg) lowered WBC numbers in iron dextran (FeDex)-loaded mice and served as evidence of the reversal of erythrocyte superoxide dismutase activity, plasma total antioxidant capacity, and plasma and liver thiobarbituric acid-reactive substances in the loading mice. Consequently, the PRBF treatment was observed to be more effective than NAC treatment. PRBF would be a powerful supplementary and therapeutic antioxidant product that is understood to be more potent than NAC in ameliorating the effects of iron-induced oxidative stress.

Dielectric barrier discharge (DBD) plasma has been found to uniquely polymerize ribose that is not usually subject to polymerization since molecules that tend to polymerize almost always possess at least a π-bond. The polymer was analyzed via nuclear magnetic resonance (NMR) spectra, matrix-assisted laser desorption ionization time-of-flight (MALDI TOF) mass spectroscopy and Fourier-Transform inferred spectroscopy (FTIR), and it was found that dehydration occurs during polymerization.

In this paper, polypropylene (PP) melt blown non-woven fabric is treated by atmospheric pressure N2 or N2/CO2 dielectric barrier discharge (DBD) plasma. The variation of the surface hydrophilicity of PP sample is experimentally investigated by surface water contact angle, Fourier transform infrared reflectance spectroscopy (FTIR-ATR). The results show that the hydrophilicity of PP sample is considerably improved as long as the very short plasma treatment time (several seconds). However, the treatment effect of atmospheric N2/CO2 plasma is worse than that of atmospheric N2 plasma.

Many studies introduced cold plasma as a novel and effective processing technology for microbial decontamination of food and water as well as for the removal of environmental pollution such as pesticide. However, as there are several types of plasma designs, their efficacy in degrading major pesticide residues, such as chlorpyrifos (as a hazardous chemical), should be explored. This study was conducted to assess the decontamination efficacy of 8 min of arc and dielectric barrier discharge (DBD) plasma on chlorpyrifos pesticide-water samples at a con-centration of 2 mg·L-1. The plasma-treated samples were assessed by liquid chromatography-mass spectrometry (LC-MS) and compared with the control (untreated) sample. In addition, the effects of plasma processes on some physical properties of samples were studied. According to the results, plasma-treated samples showed similar physical characteristics (e.g., refractive index and color values) to those of the untreated samples. While the temperature of the samples remained steady during the DBD plasma treatment, arc plasma changed the temperature of the sample at a rate of about 3.75°C·min–1 and yielded a sample with a final temperature of 60°C. However, contrary to the general belief that plasma is an efficient technique for pesticide degradation, chemical analyses showed high resistance of chlorpyrifos against both arc and DBD plasma under the conditions used in the present study. Therefore, the possibility of high resistance of pesticide pollution to this emerging technology should be considered. Also, further studies on the efficiency of the selected plasma system for removing pesticide pollution (e.g., during water and wastewater treatment) at industrial scale is needed.

We present a method to prepare polyaminophenol from solid-state aminophenol monomers using atmospheric dielectric barrier discharge (DBD) plasma. The polymerizations of o-aminophenol and m-aminophenol are studied. The polymers were analyzed via Fourier-Transform inferred spectroscopy (FTIR) and ultraviolet-visible (UV-vis) spectroscopy. The kinetics of the polymerization reactions were investigated by using UV-vis and the polymerization was found to be first-order for both o-aminophenol and m-aminophenol. The resulting polymer film exhibits a conductivity of 1.0 × 10−5 S/m for poly-o-aminophenol (PoAP) and 2.3 × 10−5 S/m for poly-m-aminophenol (PmAP), which are two orders more conductive than undoped (~10−7 S/m) polyaniline (PANI), The PoAP has a quinoid structure and the PmAP has an open ring keto-derivative structure. The process provides a simple method of preparing conductive polyaminophenol films.

ABSTRACTOxidative stress leads to membrane lipid peroxidation, which yields products causing variable degrees of detrimental oxidative modifications in cells. Reactive oxygen species (ROS) are the key regulators in this process and induce lipid peroxidation inEscherichia coli. Application of nonthermal (cold) plasma is increasingly used for inactivation of surface contaminants. Recently, we reported a successful application of nonthermal plasma, using a floating-electrode dielectric-barrier discharge (FE-DBD) technique for rapid inactivation of bacterial contaminants in normal atmospheric air (S. G. Joshi et al., Am. J. Infect. Control 38:293-301, 2010). In the present report, we demonstrate that FE-DBD plasma-mediated inactivation involves membrane lipid peroxidation inE. coli. Dose-dependent ROS, such as singlet oxygen and hydrogen peroxide-like species generated during plasma-induced oxidative stress, were responsible for membrane lipid peroxidation, and ROS scavengers, such as α-tocopherol (vitamin E), were able to significantly inhibit the extent of lipid peroxidation and oxidative DNA damage. These findings indicate that this is a major mechanism involved in FE-DBD plasma-mediated inactivation of bacteria.
