Azul de metileno no tratamento da síndrome vasoplégica em cirurgia cardíaca. quinze anos de perguntas, respostas, dúvidas e certezas
(2009-07-01)
Objective: There is strong evidence that methylene blue (MB), an inhibitor of guanylate cyclase, is an excellent therapeutic option for vasoplegic syndrome (VS) treatment in heart surgery. The aim of this article is to ...
Photocatalytic degradation of methylene blue by TiO2-Cu thin films: Theoretical and experimental study
(Elsevier B.V., 2010-12-15)
In this work the effect of doping concentration and depth profile of Cu atoms on the photocatalytic and surface properties of TiO2 films were studied. TiO2 films of about 200 nn thickness were deposited on glass substrates ...
Reliability of assessing dye penetration along root canal fillings using methylene blue
(Wiley-Blackwell Publishing, Inc, 2009-12-01)
Methylene blue (MB) remains the most frequently used tracer for dye penetration tests of endodontic fillings, despite its chemical reactions with different materials. This study checked whether dye penetration displayed ...
Photodynamic therapy for American cutaneous leishmaniasis: The efficacy of methylene blue in hamsters experimentally infected with Leishmania (Leishmania) amazonensis
(Academic Press Inc. Elsevier B.V., 2011-08-01)
The aim of this study was to investigate the effectiveness of Photodynamic Therapy (PDT) using Methylene Blue (MB) as the photosensitizing compound and a Light-Emitting Diode (LED) in American cutaneous leishmaniasis (ACL). ...
Photosensitization of different Candida species by low power laser light
(Elsevier B.V., 2006-04-03)
The aim of this study was to evaluate the effects of the laser radiation (685 nm) associated with photosensitizers on viability of different species of Candida genus. Suspensions of Candida albicans, Candida dubliniensis, ...
The effect of endodontic materials on the optical density of dyes used in marginal leakage studies
(2008-01-01)
The aim of this study was to determine the effect of the exposure of different endodontic materials to different dye solutions by evaluating the optical density of the dye solutions. Seventy-five plastic tubes were filled ...
Synthesis and Characterization of Methylene Blue-Containing Silica-Coated Magnetic Nanoparticles for Photodynamic Therapy
(Amer Scientific Publishers, 2017)
Superparamagnetic iron oxide nanoparticles (SPIONs), with appropriate surface coating, are commonly used for biomedical applications such as photodynamic therapy (PDT). This work describes the preparation and characterization ...
Study of the interaction between cardiolipin bilayers and methylene blue in polymer-based Layer-by-Layer and Langmuir films applied as membrane mimetic systems
(Elsevier B.V., 2010-11-18)
An increase of the reports involving mimetic systems has been observed. Briefly, these systems use biological phospholipids to exploit specific interactions between membrane-models and drugs. Here, the Layer-by-Layer (LbL) ...
The Methylene Blue Self-aggregation in Water/Organic Solvent Mixtures: Relationship Between Solvatochromic Properties and Singlet Oxygen Production
(Univ Federal Mato Grosso Sul, Dept Quimica, 2017)
In this work is presented a spectrophotometric investigation focused on the solvatochromic effects upon Methylene Blue (MB). Measurements were carried out in four different water/organic solvent mixtures: low polarity ...
