Photodynamic inactivation using a chlorin-based photosensitizer with blue or red-light irradiation against single-species biofilms related to periodontitis
(2020-09-01)
Chlorin-e6 (Ce6), as a photosensitizer (PS), has demonstrated significant reduction of microorganisms’ viability when irradiated by red light. However, the main absorption peak of this PS is located at blue light spectrum, ...
Photodynamic properties and photoinactivation of Candida albicans mediated by brominated derivatives of triarylmethane and phenothiazinium dyes
(Elsevier Science, 2014-04)
The photodynamic activity of brominated derivatives of New Fuchsin and Azure B was studied in solution and in cell suspensions of Candida albicans. The spectroscopic and photodynamic properties of these photosensitizers ...
Photodynamic inactivation of clinical isolates of Candida using Photodithazine®
(Taylor and FrancisAbingdon, 2013)
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 ...
Curcumin-mediated photodynamic inactivation of Candida albicans in a murine model of oral candidiasis
(2013-04-01)
In vitro investigations of curcumin-mediated photodynamic therapy (PDT) are encouraging, but there is a lack of reliable in vivo evidence of its efficacy. This study describes the photoinactivation of Candida albicans in ...
Comparative study between photodynamic and antibiotic therapies for treatment of footpad dermatitis (bumblefoot) in Magellanic penguins (Spheniscus magellanicus)
(Elsevier B.V., 2015-03-01)
Background: Bumblefoot, referring to bed-sore-like foot lesions, is one of the most important clinical complications in captive birds and has a multifactorial etiology. Photodynamic therapy has been proposed as an alternative ...
Clinical Comparison of Two Photosensitizers for Oral Cavity Decontamination
(2017-02-01)
Objective: In this study, we aim to compare the photodynamic inactivation (PDI) effects of two different photosensitizers (PS), Photogem® and Natural Curcumin, irradiated with light-emitted diodes (LED) at 630 and 450 nm, ...
Assessment of chitosan-based hydrogel and photodynamic inactivation against propionibacterium acnes
(2018-01-01)
Chitosan (CH) is a biopolymer that exhibits a number of interesting properties such as anti-inflammatory and antibacterial activity and is also a promising platform for the incorporation of photosensitizing agents. This ...
Photodynamic Inactivation of Cariogenic Pathogens Using Curcumin as Photosensitizer
(2017-05-01)
Objective: This investigation assessed the susceptibility of Streptococcus mutans and Lactobacillus acidophilus to Photodynamic Therapy (PDT) when grown simultaneously in dentine carious lesions. Background data: PDT is a ...
In vivo evaluation of photodynamic inactivation using Photodithazine (R) against Candida albicans
(Royal Soc Chemistry, 2015-01-01)
This study describes the photoinactivation of Candida albicans in a murine model of oral candidosis, mediated by Photodithazine (R) (PDZ). Six-week-old female Swiss mice were immunosuppressed, and inoculated with C. albicans ...
Photodynamic potential of curcumin in bioadhesive formulations: Optical characteristics and antimicrobial effect against biofilms
(2021-09-01)
Background: Although Curcumin (CUR) has great potential as a photosensitizer, the low solubility in water impairs its clinical performance in photodynamic inactivation (PDI). This study sought to establish an effective ...
