Hepatogenous photosensitization by Brachiaria spp. in sheep: first report in Mexico

Brazilian Journal of Veterinary Pathology, 2019
Ruminants are highly susceptible to photosensitization caused by the ingestion of hepatotoxic plants. In two adjacent farms in Colima, Mexico, several sheep exhibited signs of depression and crusting dermatitis involving the ears, periorbital skin ...

Light‐Activatable Nitric Oxide Release via Intramolecular Electron Transfer for Tumor Pyroptosis Induction

Advanced Science, EarlyView.
This work proposes a novel strategy to fabricate unimolecular pyroptosis photoinitiators activated by deep‐red light at low light doses. It relies on a photosensitization mechanism to trigger nitric oxide (NO) release from benzisothiadiazole‐based N‐nitrosanilines without modification of nitro moieties, thereby boosting pyroptosis‐mediated ...

Pediatric photosensitivity [PDF]

Photodermatology, Photoimmunology & Photomedicine, 2012
SummaryPhotosensitivity is a rarely encountered problem in the pediatric population. It may be caused by a diverse group of primary, idiopathic photosensitivity conditions, or may reflect photoexacerbation of an existing dermatosis. In addition, there are several genodermatoses, metabolic disorders, and connective tissue disorders that can present with

Photosensitization of A2E triggers telomere dysfunction and accelerates retinal pigment epithelium senescence

Cell Death and Disease, 2018
Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss in elderly people. AMD is classified as early, intermediate, advanced non-neovascular, and advanced neovascular forms depending on the clinical features. However, the
