Small scale trial of photodynamic treatment of onychomycosis in São Paulo [PDF]

The use of methylene blue and toluidine blue in the photodynamic treatment of onychomycosis at an ambulatory clinic in São Paulo, Brazil is reported. Local application and illumination of infected nails produced a response in 53 of 62 patients, without ...

Photodynamic inactivation increases cell death rate on persistent Staphylococcus aureus

Photochemistry and Photobiology, EarlyView.
Persistent bacteria have the ability to survive extended periods of antibiotic stress by entering a metabolically dormant state. This study investigated persistence formation in two S. aureus strains and evaluated the effects of PDI using curcumin. Post‐PDI time‐kill assays conducted after metabolic recovery showed a higher rate of bacterial death ...

The role of constitutive nitric‐oxide synthase in regulation of IKKα after ultraviolet irradiation

Photochemistry and Photobiology, EarlyView.
cNOS enhances IKKα expression following UVB exposure by promoting promoter activation, transcriptional elongation, and Ets‐1 stabilization. These actions sustain IKKα levels, reduce UV‐induced skin carcinogenesis, and highlight cNOS as a key protective factor against solar UV damage.

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.

Advantages of horizontal centrifugation of platelet‐rich fibrin in regenerative medicine and dentistry

Periodontology 2000, EarlyView.
Abstract The aim of this comprehensive review was to evaluate comparative studies on horizontal and fixed‐angle centrifugation methods for preparing platelet‐rich fibrin (PRF). Furthermore, additional studies utilizing horizontal PRF (H‐PRF) were systematically investigated.

Novel and emerging antimicrobial strategies in the management of oral infections

Periodontology 2000, EarlyView.
Abstract Background Antibiotics marked a pivotal turning point in human civilization, enhancing social interactions and extending human life expectancy. In addition to their success in treating systemic infectious diseases, they have significantly improved periodontal treatment outcomes as an adjunct therapy.

Cold atmospheric plasma degrades methylene blue and shifts bacterial inactivation during photodynamic therapy

Scientific Reports
Photodynamic therapy (PDT) and cold atmospheric plasma can inactivate bacteria via oxidative stress. Here we examined their combined action against Staphylococcus aureus (S. aureus) using methylene blue (MB)-mediated PDT with a red organic light-emitting

Dyes, flies, and sunny skies: photodynamic therapy and neglected tropical diseases [PDF]

Photodynamic therapy, in its various applications, represents the focused combination of electromagnetic radiation, a chemical (usually a dye) capable of its absorption and conversion, and oxygen to provide cytotoxicity (cell killing).
