Reactivation of photodynamically inactivated lambda phages

Molecular and General Genetics MGG, 1968
UV-irradiated λc phages show a lower survival when plated on rec −-cells as compared to rec +-cells. Photodynamically inactivated λc phages show the lowest survival on hcr −; rec −-cells. The rec-functions do not influence the repair of UV- or photodynamically induced lesions in T1 phages.

Light sources for photodynamic inactivation of bacteria

Lasers in Medical Science, 2008
Bacteria have an important role in human and animal morbidity, and a great number of them have developed antibiotic resistance. In the past recent years a new way of dealing with this problem has been studied: photodynamic inactivation. This method is based on administration of a photosensitizing substance that fixes itself in the bacterial cell ...

Photodynamic inactivation of viruses using upconversion nanoparticles

Biomaterials, 2012
Photodynamic therapy (PDT) is a promising treatment modality that utilizes light of an appropriate wavelength to excite photosensitive materials called photosensitizers, which upon excitation, generate reactive oxygen species (ROS) that are cytocidal and virucidal.

Photodynamic inactivation for controlling Candida albicans infections

Fungal Biology, 2012
Antimicrobial photodynamic therapy (APDT) combines a non-toxic dye, termed photosensitizer, which is activated by visible light of appropriate wavelength which will produce reactive oxygen species (ROS). These ROS will react with cellular components inducing oxidative processes, leading to cell death. A wide range of microorganisms, have already showed

Photodynamic inactivation of someBacillus subtilis bacteriophages

Experientia, 1967
Es wurde die photodynamische Aktivitat von 8 verschiedenen organischen Farben auf zwei Bakteriophagen SP 3 und SP 8, virulent furBacillus subtilis, mittels Inaktivationskonstanten der ersten Ordnung verglichen. Die grosste photodynamische Wirkung zeigt Methylenblau; Neutralrot und Eosin sind praktisch inaktiv.

Conformational Changes in Ribonuclease during Photodynamic Inactivation

Radiation Research, 1972
Bovine pancreatic ribonuclease A was inactivated by photodynamic treatment at pH 8 with eosin Y, FMN and methylene blue as sensitizers.

Photodynamic Inactivation of the Dermatophyte Trichophyton rubrum¶

Photochemistry and Photobiology, 2003
Dermatophytes are fungi that can cause infections (known as tinea) of the skin, hair and nails because of their ability to use keratin. Superficial mycoses are probably the most prevalent of infectious diseases worldwide. One of the most distinct limitations of the current therapeutic options is the recurrence of the infection and duration of treatment.

Photodynamic Inactivation of Herpes Simplex

JAMA, 1973
Herpes simplex virus can be inactivated if exposed to any of several heterotricyclic dyes and irradiated briefly with an ordinary fluorescent light. This finding has been applied in a double-blind study in a group of patients with at least four episodes of recurrent herpes simplex infection per year.
