In this work, we present a novel approach which demonstrates nontrivial cancer-inhibiting capabilities of spontaneous pattern-forming self-organization at the interface between atmospheric pressure glow discharge plasma and liquid media. A pronounced cancer depressing activity towards at least two kinds of human cancer cells, namely breast cancer MDAMB-231 and human glioblastoma U87 cancer lines, was demonstrated. After a short treatment at the thinly stratified selforganized plasma-liquid interface pattern, the cancer inhibiting media demonstrate well pronounced depression and apoptosis activities towards tumor cells, not achievable without interfacial stratification of plasma jet to thin (of several μm) current filaments, which therefore play a pivotal (yet still not completely clear) role in building up the cancer inhibition properties. Moreover, thinly stratified, self-organized interfacial discharge is capable to efficiently control the ROS and RNS concentrations in the cancerinhibiting media, and in particular, abnormal ROS/RNS ratios not achievable in discharges which do not form stratified thin-filament patterns could be obtained [2, 3]. These results were explained in terms of interaction of thin plasma filaments of the self-organized pattern with gas and liquid, where the unusual interaction conditions (i.e., high surface-to-volume ratios etc.) cause accumulation of ROS, RNS and other species in unusual ratios and concentrations, thus forming potentially efficient anti-cancer cocktail. Our funding could be extremely important for handling the cancer proliferation problem, and hence, it should be brought to light to attract due attention of the researchers and explore the possible potential of this approach in tackling the challenging problem of high cancer-induced mortality and rising morbidity trends.","PeriodicalId":145705,"journal":{"name":"2017 IEEE International Conference on Plasma Science (ICOPS)","volume":"56 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114036973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it has not been researched, especially stagnation and re-strike of the arc. In this paper, the process of arc moving affected by external magnetic field in magnetic driven arc is elucidated. Specifically, the behavior of magnetic driven arc with external magnetic field is measured by using the oscilloscope and HSVC (High Speed Video Camera). And an external magnetic field (1, 2, 3 mT) was applied by helmholtz coil. As a result, the arc mean moving speed increases with increasing the external magnetic field. The arc of re-strike time increases and stalemate time decreases with increasing the external magnetic field. Therefore, the anode spot moving speed increases 8 times because arc of re-strike occurs easily with the external magnetic field. Thus, the erosion of electrodes decreases and the arc moving becomes the smooth. However, the distance of re-strike decreases with increasing the external magnetic field because re-strike point is affected by cathode jet. The anode restrikes on the extension of the cathode jet. Therefore, the direction of cathode jet contributes to the process of arc moving.","PeriodicalId":145705,"journal":{"name":"2017 IEEE International Conference on Plasma Science (ICOPS)","volume":"26 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126905573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The heterogeneous composition of non-thermal atmospheric plasma offers the opportunity to intervene numerous signaling pathways that control tumor cells. Subsequently, the array of non-thermal atmospheric plasma generated products has limited the identification of the mechanisms of action on tumor cells. In this work, we will present the results of non-thermal plasma jet treated on neuroblastoma cells using a murine neuroblastoma line derived from AJ mice and cultured in D10 media. The goal of this work is to determine the cell death response of neuroblastoma cells by using a non-thermal plasma jet. The effect of variable treatment dosage levels of non-thermal plasma was tested in neuroblastoma cells. The number of viable cells was evaluated, while apoptosis and necrosis was assessed. Our observations indicate that increased treatment dosage levels of non-thermal plasma jet caused varied results from no significant changes to apoptotic characteristics to induction of necrosis at extended dosages. Overall the results suggest that non-thermal plasma jet can be of significant application to the treatment of neuroblastoma cancer cells.","PeriodicalId":145705,"journal":{"name":"2017 IEEE International Conference on Plasma Science (ICOPS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123356712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
