Immobilized photosensitizers for antimicrobial applications [PDF]

open access: yes, 2015
Photodynamic antimicrobial chemotherapy (PACT) is a very promising alternative to conventional antibiotics for the efficient inactivation of pathogenic microorganisms; this is due to the fact that it is virtually impossible for resistant strains to ...

Inactivation of Campylobacter jejuni by exposure to high-intensity 405-nm visible light [PDF]

open access: yes, 2010
Although considerable research has been carried out on a range of environmental factors that impact on the survival of Campylobacter jejuni, there is limited information on the effects of violet/blue light on this pathogen. This investigation was carried

Antimicrobial Photodynamic Inactivation and Photodynamic Therapy for Infections [PDF]

open access: yes, 2010
Photodynamic therapy (PDT) was initially discovered over 100 years ago by its ability to kill microorganisms, but its use to treat infections clinically has not been much developed. However, the present relentless increase in antibiotic resistance worldwide and the emergence of strains that are resistant to all known antibiotics has stimulated research

Absence of a dose-rate effect in the transformation of C3H 10T1/2 cells by α-particles [PDF]

open access: yes, 1987
The findings of Hill et al. (1984) on the greatly enhanced transformation frequencies at very low dose rates of fission neutrons induced us to perform an analogous study with -particles at comparable dose rates. Transformation frequencies were determined

Modulation of 5-Aminolevulinic acid mediated photodynamic therapy induced cell death in a human lung adenocarcinoma cell line [PDF]

open access: yes, 2016
Photodynamic therapy (PDT) is a cancer treatment involving the administration of a photosensitising drug which selectively accumulates in tumor tissue, followed by irradiation with appropriate wavelength light.

Photofrin II as an efficient radiosensitizing agent in an experimental tumor [PDF]

open access: yes, 2001
Background and Objective: The use of ionizing irradiation as radiation therapy (RT) for tumor treatment represents a well-established method. The use of photodynamic therapy (PDT), especially with Photofrin II, for tumor treatment is also known. Chemical

Highly efficient optogenetic cell ablation in C. elegans using membrane-targeted miniSOG. [PDF]

open access: yes, 2016
The genetically encoded photosensitizer miniSOG (mini Singlet Oxygen Generator) can be used to kill cells in C. elegans. miniSOG generates the reactive oxygen species (ROS) singlet oxygen after illumination with blue light.

Photodynamic inactivation of verrucae vulgares. II

open access: yesActa Dermato-Venereologica, 1977
Photodynamic inactivation therapy, consisting of a double-blind, paired comparison treatment schedule, was used in treating 56 patients for recalcitrant, symmetrical verrucae vulgares. 0.1% proflavine in 100% dimethylsulphoxide (DMSO) and 0.1% neutral red in 100% DMSO were used as active dyes, and 1% picric acid in 100% DMSO and 1% color ruber in 100 ...

Halo-fluorescein for photodynamic bacteria inactivation in extremely acidic conditions

open access: yesNature Communications, 2021
Photodynamic inactivation is a common antibacterial method but often fails in extremely acidic environments (pH< 4). Here, the authors demonstrate halogenation of fluorescein for the development of a photodynamic agent which works in extremely acidic ...

Photodynamic inactivation of Candida albicans by hematoporphyrin monomethyl ether [PDF]

open access: yes, 2016
AIM: To evaluate the capacity of hematoporphyrin monomethyl ether (HMME) in the presence of light to cause photodynamic inactivation (PDI) of Candida albicans. MATERIALS & METHODS: HMME photoactivity was evaluated against azole-susceptible and -resistant
