AB  - Intensive use of pesticides requires innovative approaches for their removal from the environment. Here we report the method for degradation of dimethoate in water using non-thermal plasma needle and analyze kinetics of dimethoate removal and possible degradation pathways. The effects of dimethoate initial concentration, plasma treatment time, Argon flow rate and the presence of radical promoters on the effectiveness of proposed method are evaluated. With argon flow rate of 0.5 slm (standard litres per minute) 1 × 10−4 M dimethoate can be removed within 30 min of treatment. Using UPLC analysis it was confirmed that one of the decomposition products is dimethoate oxo-analogue omethoate, which is in fact more toxic than dimethoate. However, the overall toxicity of contaminated water was reduced upon the treatment. The addition of H2O2 as a free radical promoter enhances dimethoate removal, while K2S2O8 results with selective conversion to omethoate. Using mass spectrometry in combination with the theoretical calculations, possible degradation pathways were proposed. The feasibility of the proposed method for dimethoate degradation in real water samples is confirmed. The proposed method is demonstrated as a highly effective approach for dimethoate removal without significant accumulation of undesirable toxic products and secondary waste. © 2019 Elsevier Ltd

AB  - In this study we evaluate apoptosis time window of primary fibroblasts treated with cold atmospheric plasma (CAP), power range 0.4-1.4 W, for 30 sec, using γ-H2AX phosphorylation assay and flow cytometry. In contrast to irradiation where maximum of γ-H2AX foci appeared 30 min after irradiation and apoptosis 24 h later irrespective of radiation dose, treatment with CAP (power of 0.4 and 0.6) induces maximum of γ-H2AX foci 2 h after treatment. Apoptosis occurred in a power-dependent manner, with time shift of 2-3 h. Besides power-dependent time shift in apoptosis induction, apoptosis time window is the same and lasts for 2 h. © 2019, Indian Academy of Sciences.

AB  - Undecylprodigiosin pigment (UPP) is reported to display cytotoxic activity towards various types of tumours. Nevertheless, its efficacy in modifying the cellular response to ionising radiation is still unknown. In this study, the radiomodulating effects of UPP were investigated. The effects of UPP were assessed in vitro by treating cultures of human peripheral blood with UPP and ionising radiation using two treatment regimens, the UPP pre-irradiation treatment and UPP post-irradiation treatment. The activity of UPP was investigated evaluating its effects on the radiation-induced micronuclei formation, cell proliferation, and induction of apoptosis. The redox modulating effects of UPP were examined measuring the catalase activity and the level of malondialdehyde, as a measure of oxidative stress. The results showed that UPP effects on cellular response to ionising radiation depend on its concentration and the timing of its administration. At low concentration, the UPP displayed radioprotective effects in. gamma-irradiated human lymphocytes while at higher concentrations, it acted as a radiosensitiser enhancing either mitotic catastrophe or apoptosis depending on the treatment regimen. The UPP modified redox processes in cells, particularly when it was employed prior to gamma-irradiation. Our data highlight the importance of further research of the potential of UPP to sensitize tumour cells to radiation therapy by inhibiting pathways that lead to treatment resistance.

AB  - It is known that some bacterial species are more resilient to different kinds of irradiation due to the naturally developed protective mechanisms and compounds such as pigments. On the other hand, reasoned tissue engineering using plasma remains a critical task and requires very precise control of plasma parameters in order to mitigate its potential detrimental effects. Here we isolated a natural protective agent, microbially produced undecylprodigiosin ((52)-4-methoxy-5-[(5-undecy1-1H-pyrrol2-yl)methylenel-1H,5H-2,2-bipyrrole), and investigated its effects on human blood cells independently and in combination with plasma. Two apprOaches were applied; the first, undecylprodigiosin (UP pigment) was added to the blood cultures, which then were exposed to plasma (pre-treatment); and the second- the blood cultures were exposed to plasma and then treated with pigment (post-treatment). The interactions of plasma and UP pigment with blood cells were investigated by conducting a series of biological tests providing the information regarding their genotoxicity, cytotoxicity and redox modulating activities. The exposure of cells to plasma induced oxidative stress as well as certain genotoxic and cytotoxic effects seen as elevated micronuclei incidence, decreased cell proliferation and enhanced apoptosis. In blood cultures treated with UP pigment alone, we found that both cytotoxic and protective effects could be induced depending on the concentration used. The highest UP pigment concentration increased lipid peroxidation and the incidence of micronuclei by more than 70% with maximal suppression of cell proliferation. On the contrary, we found that the lowest UP pigment concentration displayed protective effects. In combined treatments with plasma and UP pigment, we found that UP pigment could provide spatial shielding to plasma exposure. In the pre-treatment approach, the incidence of micronuclei was reduced by 35.52% compared to control while malondialdehyde level decreased by 36% indicating a significant mitigation of membrane damage induced by plasma. These results open perspectives for utilizing UP pigment for protection against overexposures in the field of plasma medicine. (C) 2016 Elsevier GmbH. All rights reserved.

AB  - WO3/TiO2 and TiO2 coatings were prepared on titania substrates using facile and cost-effective plasma electrolytic oxidation process. The coatings were characterized by X-ray diffraction, scanning electron microscopy, Raman, UV vis diffuse reflectance spectroscopy, and X-ray photoelectron spectroscopy. With increasing duration of PEO process, the monoclinic WO3 phase became dominant and new monoclinic WO2.95 phase appeared. The optical absorption edge in the WO3/TiO2 samples, enriched with WO3/WO2.96 phase, was shifted to the visible region. The photocatalytic efficiency of WO3/TiO2 and pure TiO2 samples was evaluated by performing the photodegradation experiments in an aqueous solution of Rhodamine 6G and Mordant Blue 9 under the visible and UV light. The WO3/TiO2 catalysts are much more efficient than pure TiO2 under visible light and slightly better under UV light. The improvement of photocatalytic activity in the visible region is attributed to better light absorption, higher adsorption affinity and increased charge separation efficiency.

In our previous work we have optimized plasma needle parameters to efficiently sterilize E. Coli and S. Aureus in planktonic samples without causing damage to the peripheral blood mesenchymal stem cells used as a model for surrounding tissue [3]. Plasma treatments of human periodontal ligament mesenchymal stem cells have led to a promotion of osteogenic differentiation without affecting cell viability [4]. These results can be important for dentistry, especially for possible support or alternative to conventional regenerative procedures, such as guided tissue regeneration, the use of bone replacement grafts, and application of exogenous growth factors or proteins. Besides the promising short term effects of atmospheric non-thermal plasma on cells, it is necessary to study the long term effects, like for example DNA damage in order to prevent undesirable effects.

AB  - We use human primary fibroblasts for comparing plasma and gamma rays induced DNA damage. In both cases, DNA strand breaks occur, but of fundamentally different nature. Unlike gamma exposure, contact with plasma predominantly leads to single strand breaks and base-damages, while double strand breaks are mainly consequence of the cell repair mechanisms. Different cell signaling mechanisms are detected confirming this (ataxia telangiectasia mutated - ATM and ataxia telangiectasia and Rad3 related - ATR, respectively). The effective plasma doses can be tuned to match the typical therapeutic doses of 2Gy. Tailoring the effective dose through plasma power and duration of the treatment enables safety precautions mainly by inducing apoptosis and consequently reduced frequency of micronuclei.

AB  - This study discusses the possibility of using a corona discharge at atmospheric pressure and air RF plasma at low pressure for the cotton fibre activation prior to deposition of colloidal TiO2 nanoparticles in order to enhance antibacterial, UV protective and self-cleaning properties. X-ray photoelectron spectroscopy (XPS) analysis confirmed the presence of TiO2 nanoparticles on the surface of cotton fibres. XPS elemental mapping indicated that TiO2 nanoparticles were more evenly distributed across the surface of untreated and corona pre-treated cotton fabrics in comparison with RF plasma pre-treated fabric. Atomic absorption spectroscopy measurements revealed that the equivalent total content of TiO2 in the cotton fabrics pre-treated by corona and RF plasma was 31% higher than in the fabric that did not undergo any treatment prior to loading of TiO2 nanoparticles. In order to achieve maximum bacteria (Gram-negative bacteria Escherichia coli) reduction, untreated cotton fabric had to be loaded with colloidal TiO2 nanoparticles twice, but only once following corona or RF plasma pre-treatment. Deposition of TiO2 nanoparticles onto cotton fabrics provided maximum UV protective rating of 50+. Extraordinary photocatalytic activity of TiO2 nanoparticles deposited onto cotton fabrics was proved by self-cleaning of blueberry juice stains and photodegradation of methylene blue in aqueous solution under UV illumination.

AB  - The potential application of low-temperature radio frequency (RF) plasma for fiber surface activation in order to enhance the binding efficiency of colloidal silver nanoparticles onto the polyester fabrics and improve the stability of antibacterial effects was studied. Antibacterial activity and laundering durability were tested against gram-negative bacterium Escherichia coli and gram-positive bacterium Staphylococcus aureus. Plasma treatment positively affected the loading of silver nanoparticles as well as antibacterial activity and laundering durability of these textile nanocomposite materials. In spite of good laundering durability after five washing cycles, it was found that silver leached from the fabric into the bath during washing. Released silver from the washing effluent was efficiently removed by recycled wool-based nonwoven sorbent modified with hydrogen peroxide and biopolymer alginate.

AB  - The aim of this study was to highlight the possibility of using the air RF plasma for fiber surface activation that can facilitate the deposition of silver nanoparticles from colloid onto the polyester fabrics and thus, enhance their antibacterial properties. The deposition of silver nanoparticles caused significant morphological changes as well as the color change of polyester fabrics. Untreated polyester fabrics and polyester fabrics activated by air RF plasma, both, subsequently modified by silver nanoparticles exhibited excellent antibacterial properties against Gram-negative bacterium E. coli and Gram-positive bacterium S. aureus. However, polyester fabrics activated by plasma provided better laundering durability of achieved effects.
