BACKGROUND AND OBJECTIVE With advances in mammographic equipment and techniques, more and more nonpalpable breast lesions have been detected. This study was to investigate the application of methylene blue dye for localized biopsy to diagnose nonpalpable breast lesions. METHODS In total 138 patients with suspicious malignant, nonpalpable breast lesions between August 2002 and October 2006 wer...

This study examines the sorption of methylene blue on the cheap unconventional bio sorbents, citrus fruits: oranges and lemons. Bio sorbents which was used was: orange and lemon peel, seeds and pulp. The results are compared with results of sorption to mineral sorbents, zeolite clinoptilolite, Pyrolox and Birm. Sorption kinetics and the influence of pH on the sorption of methylene blue on orang...

Methylene blue has been shown to be neuroprotective in multiple experimental neurodegenerative disease models. However, the mechanisms underlying the neuroprotective effects have not been fully elucidated. Previous studies have shown that macroautophagy has multiple beneficial roles for maintaining normal cellular homeostasis and that induction of macroautophagy after myocardial ischemia is pro...

The objective of this study was to elucidate the mechanisms associated with the reciprocal relation between magnesium and calcium on vascular smooth muscle tone in bovine pulmonary artery and vein. Rapid removal of magnesium from Krebs-bicarbonate medium used to bathe isolated rings of precontracted artery or vein caused transient endotheliumand calciumdependent relaxation and cyclic GMP accumu...

PURPOSE To report a case of autonomic, neurological and neuromuscular instability following methylene blue infusion for parathyroidectomy; to advance the argument for a diagnosis of serotonin syndrome; and to consider this diagnosis in previous, unexplained reports of adverse reactions amongst patients undergoing parathyroidectomy using methylene blue. CLINICAL FEATURES Methylene blue was adm...

Surface enhanced Raman scattering (SERS) and molecular fluorescence are used to probe the structure of a methylene blue monolayer adsorbed onto a sulfur-modified polycrystalline gold electrode. Changes in the wavelength of fluorescence for methylene blue on the gold electrode as compared to dilute solution indicate that the dye molecules' state of aggregation and electronic structure have been ...

This reaserch aims at functionalizing magnetic mesoporous silica with methacrylic acid-3-aminopropyltriethoxysilane (Fe3O4@MCM-41@MAA-APTES) applied for removal of methylene blue from aqueous solution. Several variables (such as pH, dye concentration, adsorbent amount and contact time) have been investigated. Under optimum conditions, maximum capacity of 87.71 mg g-1 of MB was obtained for the ...

This case report highlights an unusual case where a foreign body in the parotid gland was initially thought to be sialolithiasis based on CT scans. The foreign body was safely retrieved from the parotid gland without formal superficial parotidectomy using methylene blue and an image intensifier to localize the lesion. Diagnosis and management of foreign bodies in the parotid gland are reviewed,...
