Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well a...

The effect of methylene blue on the disposition of ethanol was studied in rats and humans. Methylene blue increased the metabolism of [(14)C]ethanol to (14)CO(2) in isolated hepatocytes and in intact rats by 75% and 30%, respectively. In healthy volunteers, methylene blue did not affect the pharmacokinetics of ethanol and did not alleviate the ethanol-induced NAD redox changes as reflected by t...

the nano sized tio2 and zno are the most active photocatalysts.  methylene blue was used as a reference molecule for the photocatalytic degradation. the tio2 and zno can totally remove methylene blue dye. the effect of various process parameters like initial concentration, contact time, dose of catalyst and ph on the extent of removal of dye by photocatalysis in presence of tio2 and zno was stu...

1. Methylene blue has no catalytic effect on the oxygen consumption of those normal adult tissues which do not possess aerobic glycolysis. The dye increases the oxygen consumption of these tissues when their respiration has been inhibited by the addition of KCN and their fermentative power thus brought into action. 2. Methylene blue increases the oxygen consumption of normal tissues having aero...

First, in the author’s study methylene blue was administered in a dose of 1–2 mg/kg bolus over 10 min and the median time until a maximum hemodynamic response was 2 h after drug administration. Out of 88 patients who received methylene blue, only 39 (44.3%) showed a positive hemodynamic response to the drug. We believe that if the bolus of methylene blue was followed by a continuous infusion of...

Methylene blue, currently in phase 3 clinical trials against Alzheimer Disease, disaggregates the Tau protein of neurofibrillary tangles by oxidizing specific cysteine residues. Here, we investigated if methylene blue can inhibit caspases via the oxidation of their active site cysteine. Methylene blue, and derivatives, azure A and azure B competitively inhibited recombinant Caspase-6 (Casp6), a...

Preoperative localization is necessary prior to video assisted thoracoscopic surgery for the detection of small or deeply located lung nodules. We compared the localization ability of a mixture of lipiodol and methylene blue (MLM) (0.6 mL, 1:5) to methylene blue (0.5 mL) in rabbit lungs. CT-guided percutaneous injections were performed in 21 subjects with MLM and methylene blue. We measured the...

Purpose To investigate the sustained-attention and memory-enhancing neural correlates of the oral administration of methylene blue in the healthy human brain. Materials and Methods The institutional review board approved this prospective, HIPAA-compliant, randomized, double-blinded, placebo-controlled clinical trial, and all patients provided informed consent. Twenty-six subjects (age range, 22...
