The application of toxic triphenylmethane dyes such as crystal violet (CV) in various industrial processes leads to large amounts of dye-contaminated sludges that need to be detoxified. Specific bacteria residing in wastewater treatment plants (WWTPs) are able to degrade triphenylmethane dyes. The objective of this work was to gain insights into the genetic background of bacterial strains capab...
BACKGROUND Signet ring cell carcinoma of the colon and rectum is rare, and most cases are detected at an advanced stage. We present a case of primary signet ring cell carcinoma detected at an early stage by magnifying endoscopy with narrow-band imaging (NBI) and crystal violet staining. CASE PRESENTATION A 73-year-old man visited our hospital for screening colonoscopy. Six years previously, h...
Abstract The demand for clean water free of pollution has become an urgent priority humanity. Gd 2 Zr O 7 nanoparticles were successfully synthesized via sol–gel auto combustion as a type pyrochlore to be used in the dye phytoremediation using Fenton-like approach. have been prepared auto-combustion strategy. annealing process was performed furnace at 1100 °C h form defect-fluorite structured w...
this paper reports on synthesis of a magnetic adsorbent for wastewater treatment purposes. in this regard, platanus orientalis waste leaves were chosen as a cheap material for preparing the magnetic adsorbent by loading magnetite nanoparticles on it. the synthesized adsorbent was characterized using scanning electron microscope and x-ray diffractometer. then, it was used for magnetic solid phas...
