Photosensitizing Antivirals [PDF]

open access: yesMolecules, 2021
Antiviral action of various photosensitizers is already summarized in several comprehensive reviews, and various mechanisms have been proposed for it. However, a critical consideration of the matter of the area is complicated, since the exact mechanisms ...

Effect of Photosensitization on Inactivation of Aspergillus flavus in Maize

open access: yesProceedings, 2020
Mycotoxins are naturally occurring toxins produced by certain types of fungi thatcontaminate food and feed, posing serious health risks to human and livestock. Photosensitizationis a light-based technique, which has emerged as a novel and promising green

Ibuprofen and ketoprofen potentiate UVA-induced cell death by a photosensitization process [PDF]

open access: yesScientific Reports, 2017
Nonsteroidal 2-arylproprionic acids are widely used, over-the-counter, anti-inflammatory drugs. Photosensitivity is a commonly overlooked adverse effect of these drugs.

Incidence of Photosensitization in Husbandry Animals: A Meta-Study on the Effects of Feed Diversity and Feed Choice

open access: yesAgriculture
As this is a meta-study, we examined whether plant species diversity in the feed and the possibility of feed choice would influence the number of cases of photosensitization in farm animals.

Inactivation of Possible Fungal Food Contaminants by Photosensitization [PDF]

open access: yesFood Technology and Biotechnology, 2005
Photosensitization is based on the interaction of two nontoxic, nonmutagenic and noncarcinogenic agents – photosensitizer, accumulated in the microorganism, and visible light.

PHOTOSENSITIZATION WITH BACTERIOCHLORINS

open access: yesPhotochemistry and Photobiology, 1993
Abstract— Biophysical and photobiological properties of a group of bacteriochlorins were compared with efficacy of these products for photodynamic therapy of murine tumors. Predictive factors for selective photosensitization in vivo include affinity binding to lipoproteins greater than albumin, extinction coefficient at the wavelength of irradiation ...

New Approach to Inactivation of Harmful and Pathogenic Microorganisms by Photosensitization [PDF]

open access: yesFood Technology and Biotechnology, 2005
Photosensitization is a treatment involving the administration of a photoactive compound that selectively accumulates in the target cells or microorganisms and is followed by irradiation with visible light.

Quantum effects in photosensitization: The case of singlet oxygen generation by thiothymines [PDF]

open access: yes, 2022
Photosensitization is the indirect electronic excitation of a molecule with the aid of a photosensitizer and is a bimolecular nonradiative energy transfer.

Overlooked Transformation of Nitrated Polycyclic Aromatic Hydrocarbons in Natural Waters: Role of Self-Photosensitization

open access: yes, 2023
Photochemical transformation is an important process that involves trace organic contaminants (TrOCs) in sunlit surface waters. However, the environmental implications of their self-photosensitization pathway have been largely overlooked.
