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.

Chlorophyll and Chlorophyll Derivatives Interfere with Multi-Drug Resistant Cancer Cells and Bacteria

open access: yesMolecules, 2019
Multidrug resistance (MDR) causes challenging tasks in medicine. Human cancer cells, as well as microorganisms, can acquire multiresistance due to the up-regulation of efflux pumps (ABC transporters) and are difficult to treat.

An Approach to Developing Cyanines with Upconverted Photosensitive Efficiency Enhancement for Highly Efficient NIR Tumor Phototheranostics

open access: yesAdvanced Science, 2022
Upconverted reactive oxygen species (ROS) photosensitization with one‐photon excitation mode is a promising tactic to elongate the excitation wavelengths of photosensitive dyes to near‐infrared (NIR) light region without the requirement of coherent high ...

Spontaneous and experimental poisoning by Myrocarpus frondosus in cattle

open access: yesPesquisa Veterinária Brasileira
: An outbreak of photosensitization in Holstein and Jersey cattle occurred after the passage of an extratropical cyclone in Southern Brazil. On that occasion, several trees fell, including some of the species Myrocarpus frondosus (Fabaceae family ...

Potent Virucidal Activity In Vitro of Photodynamic Therapy with Hypericum Extract as Photosensitizer and White Light against Human Coronavirus HCoV-229E

open access: yesPharmaceutics, 2022
The emergent human coronavirus SARS-CoV-2 and its high infectivity rate has highlighted the strong need for new virucidal treatments. In this sense, the use of photodynamic therapy (PDT) with white light, to take advantage of the sunlight, is a potent ...

Persistence of Photosensitivity [PDF]

open access: yesEpilepsia, 1997
Summary: Purpose: One hundred patients with photosensitive epilepsy were investigated as part of an ongoing follow‐up study. Average duration of follow‐up was 14 years; mean age at follow‐up was 27 years. Methods: All patients were EEG investigated using a standard technique of intermittent photic stimulation (IPS).
