Photodynamic inactivation of poliovirus

Virology, 1963
Abstract Poliovirus, as usually found in fluids of infected cultures, cannot be inactivated photodynamically in the presence of heterotricyclic dyes. However, if the mature virus is freed of extraneous organic material, dyes can attach to the virus and render it light-sensitive.

PHOTODYNAMIC INACTIVATION OF LYSOZYME BY EOSIN

Photochemistry and Photobiology, 1973
Abstract— It has been demonstrated that singlet oxygen is the major oxidizing entity in the photo‐dynamic inactivation of hen egg white lysozyme by eosin, using D2O to enhance the solvent‐induced decay lifetime, and azide ion as a specific scavenger.

Buckminsterfullerene and photodynamic inactivation of viruses

Reviews in Medical Virology, 1998
The development of new virus inactivation procedures has become an area of growing interest mainly due to increased demands concerning the safety of biological products. Photochemical processes represent the most promising methods for the future to inactivate viruses. In these methods, dyes are the most widely used photosensitising reagents.

PHOTODYNAMIC INACTIVATION OF CHINESE HAMSTER CELLS

Photochemistry and Photobiology, 1983
Abstract— Visible light exposures have been shown to kill acriflavine bound Chinese hamster cells. Such killing was enhanced when (a) dye was present in the medium during irradiation and (b) the pH of the medium was 8.5, instead of the normal 7.5 during the exposure.

Photodynamic inactivation and its repair in mycoplasmas

Biochimica et Biophysica Acta (BBA) - General Subjects, 1978
Photodynamic inactivation is the loss in viability observed when organic dye-treated cells are exposed to visible light and molecular oxygen. The photodynamic inactivation of mycoplasmas, the smallest free living cells, has been studied. Depending on the extent of inactivation in Acholeplasma laidlawii, photodynamic induced damage can be repaired if ...

Photodynamic inactivation of simian immunodeficiency virus

Journal of Virological Methods, 1989
A photodynamic flow system employing a dihematoporphyrin ether (DHE) was tested for its ability to inactivate the in vitro infectivity of simian immunodeficiency virus (SICMac) at 630 +/- 5 nm with a light fluence of 5 J/cm2. Cell-free SIVMac was inactivated by photoactivated hematoporphyrin derivative in a dose-dependent fashion.

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 in Experimental Herpetic Keratitis

Archives of Ophthalmology, 1975
The effect of photodynamic inactivation on experimental herpes simplex keratitis in rabbits was investigated using neutral red as a photosensitizing dye followed by exposure to light at 425nm. Combined dye application and light exposure early in the disease (two days following infection) reduced to a minimal extent the severity and duration of the ...
