  • Methylene Blue dye as an alternative to isosulfan Blue dye for sentinel lymph node localization
    Annals of Surgical Oncology, 2003
    Co-Authors: Rache M Simmons, Sarmela Thevarajah, Meghan Brennan, Paul J Christos, Michael P Osborne
    Abstract:

    Background: Our study describes the use of Methylene Blue dye as an alternative to isosulfan Blue dye to identify the sentinel lymph node (SLN). Methods: A retrospective analysis was performed of 112 breast cancer patients (113 axillae) who underwent SLN biopsy (SLNB) with Methylene Blue dye and 99mTc-labeled sulfur colloid for SLN identification. All SLNs were submitted for intraoperative frozen section analysis, hematoxylin and eosin stain, and immunohistochemical evaluation. Patients with a pathologically negative SLN did not undergo further axillary lymph node dissection. Results: Of 112 patients who underwent SLNB, the SLN was identified in 107 (95.5%); 104 (92.8%) were identified by Methylene Blue dye. In a subset of 99 patients with recorded isotope status in relation to Blue nodes, concordant identification with both dye and isotope was observed in 94 (94.9%). Of patients with identified SLNs, 32 (29.9%) of 107 contained metastatic disease, with 31 (96.9%) of 32 identified by Methylene Blue dye. The SLN was the only positive node in 18 (60.0%) of 30 patients. Conclusions: SLNB with Methylene Blue dye is an effective alternative to isosulfan Blue dye for accurately identifying SLNs in breast cancer patients.

  • Methylene Blue dye as an alternative to isosulfan Blue dye for sentinel lymph node localization
    Breast Journal, 2001
    Co-Authors: Rache M Simmons, Sharon Smith, Michael P Osborne
    Abstract:

    Isosulfan Blue dye has been used with increasing frequency in localizing sentinel lymph nodes in breast cancer patients. Few alternative types of dye have been investigated. In a prospective study of 30 patients, Methylene Blue dye was used instead of isosulfan Blue dye to localize the sentinel lymph node. The Methylene Blue dye localization technique was successful in 90% of patients. These results are similar to those for isosulfan Blue dye. This study describes Methylene Blue dye localization as a successful alternative to isosulfan dye in identifying the sentinel node in breast cancer patients. The Methylene Blue dye technique offers a substantial cost reduction.

  • adsorption of Methylene Blue onto bamboo based activated carbon kinetics and equilibrium studies
    Journal of Hazardous Materials, 2007
    Co-Authors: B H Hameed, Azam Mohd T Din, A L Ahmad
    Abstract:

    Abstract Bamboo, an abundant and inexpensive natural resource in Malaysia was used to prepare activated carbon by physiochemical activation with potassium hydroxide (KOH) and carbon dioxide (CO 2 ) as the activating agents at 850 °C for 2 h. The adsorption equilibrium and kinetics of Methylene Blue dye on such carbon were then examined at 30 °C. Adsorption isotherm of the Methylene Blue (MB) on the activated carbon was determined and correlated with common isotherm equations. The equilibrium data for Methylene Blue adsorption well fitted to the Langmuir equation, with maximum monolayer adsorption capacity of 454.2 mg/g. Two simplified kinetic models including pseudo-first-order and pseudo-second-order equation were selected to follow the adsorption processes. The adsorption of Methylene Blue could be best described by the pseudo-second-order equation. The kinetic parameters of this best-fit model were calculated and discussed.

  • removal of Methylene Blue from wastewater using fly ash as an adsorbent by hydrocyclone
    Journal of Hazardous Materials, 2008
    Co-Authors: K Rastogi, J N Sahu, C Meikap, Manindra Nath Iswas
    Abstract:

    The excessive release of color into the environment is a major concern worldwide. Adsorption process is among the most effective techniques for color removal from wastewater and fly ash has been widely used as an adsorbent. Therefore, this study was carried out to understand the adsorption behavior of Methylene Blue from aqueous systems onto fly ash using the continuous mode. Continuous mode sorption experiments were carried out to remove Methylene Blue from its aqueous solutions in hydrocyclone equipment. The experiments were performed at constant temperature and dimensions of hydrocyclone with variation of flows through the equipment, concentrations of Methylene Blue solutions and fly ash concentration, respectively. A maximum removal of 58.24% was observed at adsorbent dosage of 900 mg/l at pH 6.75 for an initial Methylene Blue concentration of 65 mg/l.
