Photodynamic inactivation of planktonic cultures of Streptococcus mutans using erythrosine irradiated by LEDInativação fotodinâmica de culturas planctônicas de Streptococcus mutans usando eritrosina irradiada por LED
(2020-04-01)
Objective: The aim of this in vitro study was to evaluate the efficacy of photodynamic inactivation (PDI) with erythrosine (E), using a light-emitting diode (LED) on planktonic cultures of Streptococcus mutans. Material ...
Photodynamic inactivation of a multispecies biofilm using curcumin and LED light
(2016-07-01)
This study evaluated the potential of curcumin-mediated antimicrobial photodynamic inactivation (API) on multispecies biofilms of Candida albicans, Candida glabrata, and Streptococcus mutans of different ages. Acrylic ...
Photodynamic inactivation of Candida albicans and Candida tropicalis with aluminum phthalocyanine chloride nanoemulsion
(2019-01-01)
The in vitro susceptibilities of Candida albicans and Candida tropicalis to Antimicrobial Photodynamic Treatment with aluminum phthalocyanine chloride in nanoemulsion (ClAlPc/NE) were investigated. PS concentration- and ...
Photodynamic inactivation of clinical isolates of Candida using Photodithazine
(2013-09-20)
This study evaluated the photodynamic inactivation (PDI) mediated by Photodithazine® (PDZ) against 15 clinical isolates of Candida albicans, Candida glabrata and Candida tropicalis. Each isolate, in planktonic and biofilm ...
Photodynamic inactivation mediated by methylene blue or chlorin e6 against Streptococcus mutans biofilm
(2020-09-01)
Background: An appropriate photosensitizer (PS) for photodynamic inactivation should have a pronounced antimicrobial efficacy but low dark toxicity. The aim of this study is to investigate the concentration-dependent ...
Photodynamic inactivation of Streptococcus mutans and Streptococcus sanguinis biofilms in vitro
(2013-05-01)
The purpose of this study was to evaluate specific effects of photodynamic inactivation (PDI) using erythrosine (ER) and Rose Bengal (RB) photosensitizers and a blue light-emitting diode (LED) on the viability of Streptococcus ...
Synthesis, spectroscopic properties and photodynamic activity of porphyrin–fullerene C60 dyads with application in the photodynamic inactivation of Staphylococcus aureus
(Elsevier Masson, 2014-07)
A covalently linked porphyrin–fullerene C60 dyad 5 was synthesized by 1,3-dipolar cycloaddition using 5-(4-formylphenyl)-10,15,20-tris[3-(N-ethylcarbazoyl)]porphyrin, N-methylglycine and fullerene C60. Methylation of 5 was ...
Photodynamic inactivation in the expression of the Candida albicans genes ALS3, HWP1, BCR1, TEC1, CPH1, and EFG1 in biofilms
(2018-09-01)
The objective of this study was to evaluate the effects of photodynamic inactivation (PDI) on Candida albicans biofilms, evaluating its effects on gene expression of ALS3, HWP1, BCR1, TEC1, CPH1, and EFG1 by yeast. Three ...
The influence of photodynamic therapy parameters on the inactivation of Candida spp: in vitro and in vivo studies
(Iop Publishing Ltd, 2014-04-01)
The influence of parameters of photodynamic therapy (PDT), such as pre-irradiation time (PIT), on the inactivation of Candida spp. was assessed in vitro and in vivo. Suspensions of Candida albicans, Candida tropicalis, ...
Photodynamic inactivation mechanism of Streptococcus mitis sensitized by zinc(II) 2,9,16,23-tetrakis[2-(N,N,N-trimethylamino) ethoxy]phthalocyanine
(Elsevier, 2013-06)
Photoinactivation of Streptococcus mitis induced by zinc(II) 2,9,16,23-tetrakis[2-(N,N,N-trimethylamino)ethoxy]phthalocyanine (ZnEPc4+) was studied under different experimental condition in order to obtain information about ...
