The effect of various reaction parameters such as concentration of the dye, catalyst dosage, temperature, pH, dissolved oxygen etc. as well as the addition of oxidisers and presence of salts in water on the rate of degradation has been evaluated and optimised. The degradation follows variable kinetics depending on the concentration of the substrate, the order of reaction varying from 1 to 0 with increase in concentration. The reaction proceeds through a number of intermediates and many of them have been identified using GCMS technique. The intermediates do not affect the rate of degradation significantly. The influence of anions such as chloride, sulphate, fluoride, carbonate, bicarbonate, phosphate etc. on the degradation of IC is not consistent and does not follow any predictable pattern. Phosphates and fluorides inhibit the degradation while chloride, sulphate, carbonate and bicarbonate enhance. Adsorption studies of the dye in the absence as well as presence of these anions show that there may not be any direct correlation between the adsorption of the dye on the catalyst and the degradation. Oxidants such as hydrogen peroxide and persulphate enhance the degradation though the combined effect and it is less than the cumulative effect of individual components. COD measurements show that the degradation proceeds to complete mineralisation. The results will be presented and probable mechanism for the degradation will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AOP" title="AOP">AOP</a>, <a href="https://publications.waset.org/abstracts/search?q=COD" title=" COD"> COD</a>, <a href="https://publications.waset.org/abstracts/search?q=indigocarmine" title=" indigocarmine"> indigocarmine</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sonocatalysis" title=" sonocatalysis"> sonocatalysis</a> </p> <a href="https://publications.waset.org/abstracts/62167/sono-and-photocatalytic-degradation-of-indigocarmine-in-water-using-zno" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62167.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">336</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Comparison of the Indocyanine Green Dye Method versus the Combined Method of Indigo Carmine Blue Dye with Indocyanine Green Fluorescence Imaging for Sentinel Lymph Node Biopsy in Breast Conservative Therapy for Early Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nobuyuki%20Takemoto">Nobuyuki Takemoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ai%20Koyanagi"> Ai Koyanagi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masanori%20Yasuda"> Masanori Yasuda</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Yamamoto"> Hiroshi Yamamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Fluorescence imaging (FI) is one of the methods to identify sentinel lymph nodes (SLNs). However, the procedure is technically complicated and requires procedural skills, as SLN biopsy must be conducted in dim light conditions. As an improved version of this method, we introduced a combined method (Combined mixed dye and fluorescence; CMF) consisting of indigo carmine blue dye and FI. The direct visualization of SLNs under shadowless surgical light conditions is facilitated by the addition of the blue dye. We compared the SLN detection rates of CMF with that of the indocyanine green (ICG) dye method (ICG-D). Methods: A total of 202 patients with stage ≤ IIA breast cancer who underwent breast conservative therapy with separate incision from January 2004 to February 2017 were reviewed. Details of the two methods are as follows: (1) ICG-D: 2ml of ICG (10mg) was used and the green-stained SLNs were resected via a 3-4cm axillary incision; (2) CMF: A combination of 1ml of ICG (5mg) and 1-3ml of indigo carmine (4-12mg) was used. Using Photodynamic Eye (PDE), a 1.5-2 cm incision was made near the point of disappearance of the fluorescence and SLNs with intermediate color of blue and green were resected. Results: There were 92 ICG-D and 110 CMF cases. CMF resulted in a significantly higher detection rate than ICG-D (96.4% vs. 83.7%; p=0.003). This difference was particularly notable in those aged ≥ 60 years (98.3% vs. 74.3%) and individuals with BMI ≥ 25kg/m2 (90.3% vs. 58.3%). Conclusion: CMF is an effective method to identify SLNs which is safe, efficient, and cost-effective. Furthermore, radiation exposure can be avoided, and it can be performed in institutes without nuclear medicine facilities. CMF achieves a high SLN identification rate, and most of this procedure is feasible under shadowless surgical light conditions. CMF can reliably perform SLN biopsy even in those aged ≥ 60 years and individuals with BMI ≥ 25 kg/m2. <p class="card-text"><strong>Keywords:</strong> <a
