BACKGROUND Photodynamic therapy is a therapeutic modality that has consolidated its activity in the photooxidation of organic matter, which arises from the activity of reactive oxygen species. OBJECTIVE To evaluate the effect of red laser 660nm with the photosensitizer methylene blue on Propionibacterium acnes in vitro. METHOD The experimental design was distributed into four groups (1 - co...

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 o...

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...

In this study, N, Scodoped titania photocatalyst was synthesized through an efficient and straight forward method using a single source, ammonium sulfate, as modification agent of titanium isopropoxide (TTIP) precursor. The catalyst was characterized by X-ray powder diffractometer (XRD), element Analysis of carbon, hydrogen, nitrogen (CHN), scanning electron microscopy (SEM), diffuse reflectanc...

About 10 years ago we discovered that bubbling nitric oxide (NO) gas into KrebsRinger bicarbonate solution containing isolated precontracted strips of bovine coronary artery caused a rapid and pronounced, but transient, relaxant response that was antagonized by oxidized hemoproteins, such as methemoglobin, and by methylene blue. NO activated soluble guanylate cyclase prepared from coronary arte...
