Simulated daylight versus conventional PDT for mild to moderate actinic keratoses: A randomized controlled trial

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
This single‐centre, randomized controlled trial showed that simulated daylight photodynamic therapy (SDL‐PDT, n = 785 lesions) was less effective than conventional photodynamic therapy (C‐PDT, n = 673 lesions) in treating mild to moderate actinic keratoses with 1‐year clearance rates of 71.0% for SDL‐PDT versus 85.3% for C‐PDT (p < 0.001). However, SDL‐

Assessing Color Inconstancy of CAD/CAM Materials: Influence of CIE White LED Illuminants and Substrate Shade

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To assess how the CIE white LED illuminants and substrate shade impact the color inconstancy of high‐translucency CAD/CAM materials. Materials and Methods From the spectral reflectance factors of Lava Ultimate‐LU, Grandio blocks‐GB, VITA Enamic‐VE, and VITA Mark II‐M specimens (n = 3/material) measured on nine background shades (ND1 ...

The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.

The effects of spectrum, irradiance, and duration of exposure on light‐induced melatonin suppression in healthy adults

open access: yesPhotochemistry and Photobiology, EarlyView.
The left panel reports the measured time course data of melatonin concentration in the blood plasma of 17 BL‐Rs and 15 BL‐NRs at baseline, during a two‐hour stay in the dark, during a one‐hour light exposure to blue light, and again in the dark. The right panel shows the magnitude of melatonin concentration after 60 min of exposure to warm white, cool ...

Use of illuminance as a guide to effective light delivery during daylight photodynamic therapy in the U.K. [PDF]

open access: yesBritish Journal of Dermatology, 2017
Daylight PDT (dPDT) is an effective and nearly painless treatment for field-change actinic keratosis. Measuring the protoporphyrin-IX (PpIX)-weighted exposure dose can give an indication of when conditions are most viable for effective dPDT. It would be advantageous for practitioners if more detailed information of exposure dose and appropriate ...

Moonlight Duration and Intensity Favour Nocturnal Activity in a Diurnal Desert Bird

open access: yesEthology, Volume 132, Issue 9, Page 629-641, September 2026.
Accelerometer data show that Canarian houbara bustards increase nocturnal activity two‐ to fivefold when the moon is visible, with activity rising as moonlit duration and illumination increase. Both display and non‐display behaviours peaked around full moon, reaching up to half of peak daytime levels, with males increasing visual displays during ...

Objective Measurement of Tooth Color Using Spectrophotometry and ICDAS: Quantifying CIELAB Color Changes Across Caries Severity

open access: yesJournal of Esthetic and Restorative Dentistry, Volume 38, Issue 9, Page 1802-1813, September 2026.
ABSTRACT Objective The International Caries Detection and Assessment System (ICDAS) is widely used for early caries detection but relies on visual interpretation. Although spectrophotometry objectively quantifies tooth color, variation across ICDAS categories and its relationship with lesion severity remain unclear. The present in vitro study therefore

Impact of Human Melanopsin Gene (OPN4) Polymorphisms (I394T, P10L) on Nocturnal Melatonin and Daily Rhythms in Young Adults

open access: yesJournal of Pineal Research, Volume 78, Issue 5, September 2026.
ABSTRACT The present study investigates the impact of two missense SNPs in the human melanopsin gene OPN4 ‐I394T (rs1079610) and P10L (rs2675703)‐ on non‐image‐forming (NIF) physiological and behavioural outputs in healthy young adults under real‐world conditions.

The Effects of Suspended Sediments, Dye, and Their Variation on Fish Behavior

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Human activities are affecting the visual environments of freshwater ecosystems by introducing visual pollutants such as artificial dyes and elevated suspended sediment levels. Our research shows that dyes and suspended sediments can have contrasting effects of fish behavior, with dye increasing and sediments decreasing movement.
