Evaluation of chitosan gel as antibiotic and photosensitizer delivery
(Informa Healthcare, 2008-01-01)
This work suggests the use of chitosan gel imbued with the photosensitizer Photogem and with the antibiotic Tetraclin as a possible drug delivery system. The results reveal a decrease in the photosensitizer level of toxicity. ...
Progress on holographic techniques to measure real-time phase and amplitude gratings in photosensitive materials
(Iop Publishing Ltd, 2003-09-01)
In this paper we present and demonstrate a technique that allows simultaneous and independent measurement of small changes in the refractive index and the absorption coefficient produced in photosensitive materials during ...
Tooth color change caused by photosensitizers after photodynamic therapy: An in vitro study
(Elsevier B.V., 2016-07-01)
This study aimed to perform an in vitro evaluation of the effect of photosensitizers used in photodynamic therapy (PDT) on tooth color change when used in combination with conventional endodontic treatment. Forty extracted ...
Hepatogenous photosensitization of ruminants by Brachiaria decumbens and Panicum dichotomiflorum in the absence of sporidesmin: Lithogenic saponins may be responsible
(1996-08-01)
As part of a study of plants involved in crystal-associated hepatogenous photosensitization diseases, samples of Brachiaria decumbens and Panicum dichotomiflorum on which cattle and goats had recently been photosensitized ...
Non-homogeneous liver distribution of photosensitizer and its consequence for photodynamic therapy outcome
(ELSEVIER SCIENCE BV, 2010)
Background: Photodynamic therapy is mainly used for treatment of malignant lesions, and is based on selective location of a photosensitizer in the tumor tissue, followed by light at wavelengths matching the photosensitizer ...
Safety assessment of oral photodynamic therapy in rats
(Springer, 2013-02-01)
Photodynamic therapy (PDT) is based on the synergism of a photosensitive drug (a photosensitizer) and visible light to destroy target cells (e.g., malignant, premalignant, or bacterial cells). The aim of this study was to ...
Lethal photosensitization in microbiological treatment of ligature-induced peri-implantitis: a preliminary study in dogs
(2003-03-01)
This pilot study evaluated, by culture testing, the effectiveness of lethal photosensitization for the microbiological treatment of peri-implantitis in dogs. Experimental peri-implantitis was induced by ligature placement ...
Comparative effects of different phenothiazine photosensitizers on experimental periodontitis treatment
(2021-06-01)
Aim: The aim of the present study was to compare the effects of the phenothiazine photosensitizers methylene blue (MB), toluidine blue-O (TBO) and butyl toluidine blue (BuTB) in antimicrobial photodynamic therapy (aPDT), ...
Photosensitivity in antimony based glasses
(Natl Inst Optoelectronics, 2001-06-01)
New glass forming systems based on Sb2O3-SbPO4 has been explored. These glasses present higher thermal stability against devitrification and higher refractive index than chalcogenide glasses. Under irradiation, using ...
