Evaluation of the Degradation of Methylene Blue Using Photocatalytic Materials
… organic pollutants, one in-situ and one ex-situ. Methylene blue was chosen as a surrogate contaminant for both studies considering well studied degradation pathway literature. The in-situ method investigates immobilizing titanium dioxide in cement paste by functionalizing it with maleic anhydride …

Use of tissue culture to investigate the effect of methylation on methylene blue cytotoxicity
… three well known, commercially available dyes, methylene blue, toluidine blue-O and Victoria blue-BO. These dyes, exploited traditionally in industry for their powers as photosensitizers, have now attracted interest as possible agents in clinical photodynamic therapy (PDT). PDT is a novel …

A Study of the Effect of Methylene Blue on Lactate Metabolism of the Dog Erythrocyte
… (1) In 1924 reported that the administration of methylene blue to dogs resulted in a hemolytic anemia, He noted that the degree of anemia was proportional to the amount of dye administered (over the dose range used), and that if the dose was quite high, hemoglobinuria and hemoglobinonia occured. …

An investigation as to the inconsistencies of the methylene blue reduction test and means of controlling same
The dissolved oxygen content of market milk fluctuates enough to cause a variation in the test.

Investigation into the potential of methylene blue and its derivatives to be used in the photodynamic therapy of non-pigmented and pigmented cells
… non porphyrin-based compounds, the cationic dye, methylene blue (MB), used traditionally as a nuclear stain in histology, has proved also to be an efficient photosensitizer, with maximum light absorption properties within the therapeutic window for PDT. Its use as a selective stain for tumour …

The Influence of Certain Lytic Agents on the Oxygen Consumption of Dog Erythrocytes
The hemolytic action of methylene blue was reported in 1924 by Huyghabaert. Doge developed anemia following the admlnistration of the dye and methylene blue was shown to produce hemolysis in vitro (l). In 1934, Wendel and Hefley observed the hemolytic property of the dye and suggested its use in …

The electrochemistry of phenothiazine derivatives
Methylene blue derivatives (MBDs) such as methylene blue (MB -), 1-methyl methylene blue (1MMB) and 1,9-dimethyl-methylene blue (DMMB) have potential use as drugs within photodynamic therapy (PDT). Knowing the redox properties of MBDs will help in understanding the way in which MBDs interact with a …

Design and synthesis of chemically-modified biosorbents for the removal of anionic metals and dye: kinetic and thermodynamic studies
… and mechanism of heavy metal chromium (VI) and methylene blue dyes in wastewater adsorbed by natural banana peel and modified banana peel are studied respectively. <br/><br/>The detailed work is as follows:<br/><br/>1 The adsorption properties of two bioadsorbents, natural banana peel and …

Dye sensitized photooxidation of toxic organic wastewaters
… wastewaters. This study investigated the use of methylene blue as a sensitizer to degrade ortho-, meta-, and para-cresol, carbofuran and acrylonitrile. Significant reductions were found when aqueous solutions of the cresol isomers and carbofuran were illuminated and aerated in the presence of …

Escherichia coli Mastitis in the Dairy Bovine
… The first experiment evaluated eosin methylene blue agar as a method of distinguishing E.coli from other gram-negative mastitis pathogens. Escherichia coli will usually produce a green metallic sheen on eosin methylene blue agar. One hundred and twenty-nine milk samples or …

Application of natural dyes in textile industry and the treatment of dye solutions using electrolytic techniques
Anodic oxidation of a commercial dye, methylene blue (MB), from aqueous solutions using an electrochemical cell is reported. Data are provided on the effects of eight different types of supporting electrolytes, concentration of electrolytes, initial dye concentration, current and electrolytic time …

Evaluation and testing of a novel photocatalytic reactor with model water pollutants.
… flow rate. In this work, the batch adsorption of methylene blue from aqueous solution (10ïM) onto the Hombikat-KCO pellet TiO2 catalyst was studied, adsorption isotherms and kinetics were determined from the experimental data. A modest catalyst loading of 30g per 1L TiO2 was choosen for further …

Comparative study of some of the methods of determining the quality of milk
… counts and some other tests, especially the methylene blue reduction test, that the lack of relation was due more to the inadequacy of the plate count method than to inadequacy of the other test. The methylene blue test showed good correlation with the plate count and is especially adapted to …

Discriminative Stimulus Effects of Putative Antipsychotic Drugs
… [SEM = ± 18.91]) to the antimalarial drug methylene blue at the 7.5 mg/kg dose, but not to the antimalarial quinacrine. This study found that the antimalarial drug methylene blue may share some pharmacological similarities or subjective effects with that of clozapine, and further studies …

Η σημασία της κηλογραφίας και της ενδοπεριτοναϊκής εγχύσεως κυανού του μεθυλενίου στην ανάδειξη και ταυτοποίηση κηλών της βουβωνικής χώρας
The technique and the results of 98 methylene-blue herniographies are reported in this study. The patients were divided in three groups. Group A included cases of clinically diagnosed primary inguinal hernia, group Β cases of probable inguinal hernia recurrence and group C cases of obscure groin …

Synthesis, characterization, and photocatalytic activity of tantalum oxide thin films
… of the films was measured using a recirculating methylene blue solution. Above 15 nm, the film thickness did not have an effect on the methylene blue degradation rate. To test the premise of being limited by electron-hole transport, the annealing temperature of the films was varied to increase …

The Development of a Vascularly Implanted Prosthetic Endocrine Pancreas
… of prototype units was studied in vitro using methylene blue, 125I-insulin and islets from lean and obese mice and optimal physical criteria, i.e. flow rate and perfusion pressure were established. Prototype units provided a constant rate of methylene blue release over a period of 7.5 hours at …
