Antimicrobial Photodynamic Inactivation and Photodynamic Therapy for Infections [PDF]

, 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

In situ photoimmunotherapy is ineffective in treating deeply invasive squamous cell carcinoma

Dermatologica Sinica, 2014
In situ photoimmunotherapy (ISPI) can be a treatment option for selected cutaneous malignancies in patients who are not surgical candidates. We herein report the case of a large, ulcerating poorly differentiated squamous cell carcinoma (SCC) affecting ...

Is the Use of Antimicrobial Photodynamic Therapy or Systemic Antibiotics More Effective in Improving Periodontal Health When Used in Conjunction with Localised Non-Surgical Periodontal Therapy? A Systematic Review

Dentistry Journal, 2019
Periodontal disease can be treated in several ways. This paper reviewed whether antimicrobial photodynamic therapy (aPDT) in addition to scaling and root planing (SRP) produces improved clinical results over systemic antibiotics (ABs) in conjunction with

Photodynamic Inactivation of Human Coronaviruses

Viruses, 2022
Photodynamic inactivation (PDI) employs a photosensitizer, light, and oxygen to create a local burst of reactive oxygen species (ROS) that can inactivate microorganisms.

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

FEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.

Photodynamic Therapy in Gastroenterology

Journal of Gastrointestinal Cancer, 2013
Photodynamic therapy (PDT) is a minimally invasive and promising new modality to combat cancer. Upon illumination and in the presence of oxygen, the tissue-localized nontoxic sensitizer generates cytotoxic reactive oxygen species, and as a result, the selective destruction of a targeted tumor may be achieved.
