..., heterogeneous outcome), emphasizing the possible need to individualize treatment. Objective: We assessed whether PDT clinical outcome and pain during treatment were correlated with protoporphyrin IX fluorescence intensity and photobleaching. Methods: 25 patients were treated by Metvix PDT. The outcome...

...Yasuhiro Fujisawa; Yasuhiro Nakamura; Yasuhiro Kawachi; Fujio Otsuka Background: Recently, indocyanine green (ICG) fluorescence imaging has been reported as new method to detect sentinel lymph nodes (SLNs). However, high introduction costs limit its use. Objective: The purpose of this study...

...Robert Brun We have carried out spectrofluorometric determinations of numerous substances such as drugs, chemicals and plants in order to find out whether there is a correlation between fluorescence data and photosensitization of the skin. A hypothesis on the mechanism of photosensitization...

...T.B. Melø; M. Johnsson The natural fluorescence from Propionibacterium acnes has been investigated in vivo. The fluorescence spectrum can be decomposed into three distinct emission spectra due to the presence of metal-free coproporphyrin, protoporphyrin and uroporphyrin in the bacteria. The amounts...

... and physically sectioning the specimen. The process is slow and subject to sample perturbation, which can result in image misinterpretation. In this study, confocal laser scanning microscopy is used successfully for the imaging of the surface and underlying morphology of unlabelled and fluorescently labelled...

... of these products. How precisely workers apply PC at the workplace can be monitored and quantified by a recently developed fluorescence technique. Objective: The goal of the present study was to use this technique to teach workers in high-risk occupations the proper use of PCs and to compare the benefit...
