Cutaneous photosensitivity of phototheranostic porphyrin–lipid nanoparticles

open access: yesPhotochemistry and Photobiology, EarlyView.
Porphyrin‐lipid nanoparticles (PORPHYSOMES) exhibit significantly less severe and shorter‐lasting skin photosensitivity to sunlight compared to a therapeutically equivalent dose of porfimer sodium (PHOTOFRIN) in a rat skin model. The difference was due to altered intradermal distribution and faster clearance of PORPHYSOMES from skin after intravenous ...

Grape constituents for protection against photodamage to skin

open access: yesPhotochemistry and Photobiology, EarlyView.
Excessive exposure to solar ultraviolet radiation has a major negative impact on the health of skin. It causes sunburn, photoaging, keratinocyte carcinomas, and melanomas. Current methods of prevention have failed to stem the incidence of these adverse effects. Grapes are natural products that are being investigated as preventive agents that can impede

Erythemal UV radiation exposure during jogging

open access: yesPhotochemistry and Photobiology, EarlyView.
Jogging is one of the most popular recreational sport activities and is done in almost all ages to keep fitness and health. However, little research has been undertaken so far to estimate UVR exposure during jogging. Therefore, we equipped a volunteer with 12 UVR meters across the body on sun‐exposed sites.

Linking the Ultraviolet Index to the “shadow rule” for sun protection: A theoretical model applied with a southern hemisphere example

open access: yesPhotochemistry and Photobiology, EarlyView.
We demonstrate the potential utility of the shadow rule and how it may be understood in relation to the UV Index. The shadow rule indirectly determines the sun's altitude by observing the length of a person's shadow during the course of the day. When the shadow cast by the sun on a horizontal surface is shorter than the height of the person casting the
