Background & objectives: The release of dyestuff wastewaters produced in textile industry into receiving waters affects both human health and the environment. The aim of this study was to investigate the efficiency of a photocatalytic UV/persulfate process in removal of methylene blue and acid green 3 dyes from aqueous solutions. Methods: The current study was an experimental study, in which t...

In this research, a novel adsorbent, tin sulfide nanoparticles coated on activated carbon [SnS-NP-C] was synthesized by a simple, low cost and efficient procedure for the removal of methylene green from aqueous solutions. Subsequently, this novel material characterization and identification has been completed by different techniques such as TEM, FT-IR, and UV-Vis ...

A 53-year-old-man with prostate cancer underwent prostate brachytherapy one month ago. Since then, he has experienced increased urinary frequency, dysuria, perineal discomfort, reduced urinary stream velocity, and nocturia. The patient was prescribed the following medications to relieve his urinary frequency and dysuria: sulfamethoxazole/trimethoprim, ciprofloxacin, tamsulosin, methylprednisolo...

In this study, citrus pectin-derived, green, and tunable carbon microspheres with superior adsorption capacity and high adsorption rate, as well as good reusability toward methylene blue adsorption, were prepared by a facile hydrothermal method without any hazardous chemicals. The materials hold great potential for the treatment of methylene blue wastewater.

OBJECTIVE To evaluate the value of microarthroscopy in the equine midcarpal joint using the vital stains methylene blue, trypan blue, neutral red, and Janus green B to observe components of the synovial lamina propria, vascular architecture, and synoviocytes. STUDY DESIGN Experimental. ANIMALS Ten horses. METHODS Microarthroscopy of left and right midcarpal joints was performed with and w...

Electrosynthesis can be carried out in emulsions formed in situ via sonication of otherwise immiscible liquid/liquid systems. The basic physical principles underlying these experiments are introduced and illustrated via three examples: the electroreduction of liquid olefins, the Kolbe electrooxidation, and the electrogeneration of leuco-methylene green.

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204986 DESCRIPTION An 85year-old man underwent reversal of loop ileostomy. The integrity of the anastomosis was tested by an injection of methylene blue into the bowel lumen. Postoperatively the patient voided ‘green urine’ and alarmed the nursing staff and junior du...
