Photodynamic inactivation of verrucae vulgares. II

Acta 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 ...

Superoxide dismutase is upregulated in Staphylococcus aureus following protoporphyrin-mediated photodynamic inactivation and does not directly influence the response to photodynamic treatment

BMC Microbiology, 2010
Background Staphylococcus aureus, a major human pathogen causes a wide range of disease syndromes. The most dangerous are methicillin-resistant S. aureus (MRSA) strains, resistant not only to all β-lactam antibiotics but also to other antimicrobials.

Antibacterial Efficacy and Mechanisms of Curcumin-Based Photodynamic Treatment against Staphylococcus aureus and Its Application in Juices

Molecules, 2022
Antimicrobial Photodynamic Treatment (aPDT) is a non-thermal sterilization technology, which can inactivate common foodborne pathogens. In the present study, photodynamic inactivation on Staphylococcus aureus (S.

Tuning riboflavin derivatives for photodynamic inactivation of pathogens [PDF]

Scientific Reports, 2021
AbstractThe development of effective pathogen reduction strategies is required due to the rise in antibiotic-resistant bacteria and zoonotic viral pandemics. Photodynamic inactivation (PDI) of bacteria and viruses is a potent reduction strategy that bypasses typical resistance mechanisms.

Sonophotodynamic Inactivation: The power of light and ultrasound in the battle against microorganisms

Journal of Photochemistry and Photobiology, 2021
The inactivation of pathogenic microorganisms that are a threat to the human being is an old challenge that needs to be overcome, mainly because microorganisms are able to develop resistance that leads to the failure of the treatment.

Synergistic effect of hypocrellin B and curcumin on photodynamic inactivation of Staphylococcus aureus

Microbial Biotechnology, 2021
Summary Antimicrobial photodynamic inactivation (aPDI) serves as a new approach to control the growth of foodborne bacteria. It remains elusive if the photodynamic efficacy of hypocrellin B (HB) can be potentiated by joint action with curcumin.

Hypericin-Mediated Photodynamic Inactivation Against the Plant Pathogen Clavibacter michiganensis: Preventative Seed Decontamination Enhanced by Potassium Iodide

Microorganisms
Clavibacter michiganensis causes significant crop losses in tomatoes, and the disease may be transferred by plant seeds. This study evaluates the efficacy of Photodynamic Inactivation (PDI) with a water-soluble hypericin derivative, developed as a ...
