Comparative mineralization of basic red 18 with electrochemical advanced oxidation processes
In this study, the role of electrochemical oxidation processes, including the electro-Fenton, the electro-persulfate (PS), and the electro/FeII/PS processes, in the removal of Basic Red 18 (BR18) from aqueous solutions was investigated. It was found that the electro-PS process successfully removes colour, but after 5 h, it produced only 75 % mineralization. In the same conditions, more effective mineralization was achieved by the electro/FeII/PS process than by the electro-Fenton method. At pH levels of 3.0 and 5.7, very effective mineralization results were produced by the electro/FeII/PS process. Moreover, the maximum mineralization current efficiency values were obtained by the electro/FeII/PS process. The mineralization efficiency of the electro/FeII/PS process was determined to be 97 % under the following conditions: BR18 initial dye concentration of 100 mg L-1, pH of 5.7, contact time of 5 h, PS concentration of 10 mM, Fe2+ concentration of 0.2 mM, and a sodium sulfate concentration of 0.05 M. © 2018 Serbian Chemical Society.

The potential efficacy of survanta® and seprafilm® on preventing intra-abdominal adhesions in rats
PubMedID: 27355746PURPOSE: To investigate the potential efficacy of beractant (Survanta®) and Seprafilm® on the prevention of postoperative adhesions. METHODS: Forty Wistar-albino female rats were used. The rats were randomly allocated into four groups of 10 rats each as control group (CG), beractant group (BG), Seprafilm® group (SG), and combined group (COG). All rats underwent cecal abrasion via midline laparotomy. Before abdominal closure, isotonic saline, beractant, Seprafilm, and combined agents were intraperitoneally administered. Adhesions were classified macroscopically with Canbaz Scoring System on postoperative day 10. Ceacum was resected for histopathological assessment. RESULTS: Macroscopic adhesion scores were significantly lower in BG, SG, and COG than CG (p<0.05); (45%, 15%, 25%, and 15%; respectively). Histopathological assessment revealed a reduced inflammation and fibrosis score in the study groups than CG (p<0.05). In BG, adhesion development, inflammation and fibrosis scores were lower than SG; however, it was not statistically significant. CONCLUSIONS: Intra-abdominal application of beractant is significantly effective for the prevention of adhesion formation with no adverse effect by covering the whole peritoneal mesothelium with excellent gliding properties in a rat model. The combination of both agents is also effective in reducing adhesion formation, however, not superior to single beractant application. © 2016,Sociedade Brasileira para o Desenvolvimento de Pesquisa em Cirurgia.
