Shade variability and stability in interim and definitive tooth‐colored resin‐based restorative materials: Comparing manufacturer‐claimed shades to a universal shade guide

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the shade variability and stability of interim and definitive tooth‐colored restorative materials by comparing manufacturer‐claimed shades to a universal shade guide before and after thermocycling. Materials and Methods Eight commercially available tooth‐colored restorative materials were tested, including conventional ...

Interventional human ocular safety experiments for 222‐nm far‐ultraviolet‐C lamp irradiation

open access: yesPhotochemistry and Photobiology, Volume 101, Issue 2, Page 517-526, March/April 2025.
To directly assess the ocular safety of 222‐nm far‐ultraviolet‐C (UVC) irradiation in humans, five subjects were exposed to 222‐nm UVC at doses of 22, 50, and 75 mJ/cm2. The findings indicate that far‐UVC irradiation does not cause “clinically significant photokeratitis” or long‐term ocular damage, though it may induce temporary discomfort.

Hydroxyaldehyde and formyl photoproducts of protoporphyrin IX formed under photodynamic diagnosis and therapy irradiation conditions

open access: yesPhotochemistry and Photobiology, EarlyView.
Photoproducts of the photosensitizer protoporphyrin IX (PpIX) may have diagnostic and therapeutic relevance in photodynamic diagnosis (PDD) and photodynamic therapy (PDT). These photoproducts possess fluorescence and photosensitizing properties and could serve as a complementary dosimetry index alongside photosensitizer photobleaching. The formation of

Cytologic Characteristics of the Feline Ovary at Different Sexual Stages

open access: yesVeterinary Clinical Pathology, EarlyView.
ABSTRACT Background Cytology is a valuable diagnostic tool in veterinary medicine, allowing rapid and minimally invasive diagnosis. However, its application in the reproductive tracts of small animals is limited, primarily used to assess mammary masses and stage the estrous cycle.

Gastrocnemius muscle properties in children with cerebral palsy: An exploratory cross‐sectional study of variability in gastrocnemius properties

open access: yesExperimental Physiology, EarlyView.
Abstract Muscle strength is a key predictor of physical functioning, yet the influence of patient and treatment factors on muscle properties in young people with cerebral palsy is not fully known. We explored whether medial gastrocnemius properties vary by age, ambulatory status and spasticity treatment (botulinum toxin or selective dorsal rhizotomy ...
