Quantum Yield Calculations for Strongly Absorbing Chromophores

, 2006
This article demonstrates that a commonly-made assumption in quantum yield calculations may produce errors of up to 25% in extreme cases and can be corrected by a simple modification to the analysis.Comment: 3 pages, 2 figures.

Does the abiotic environment influence the distribution of flower and fruit colors?

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

A UV-Independent Topical Small-Molecule Approach for Melanin Production in Human Skin

Cell Reports, 2017
The presence of dark melanin (eumelanin) within human epidermis represents one of the strongest predictors of low skin cancer risk. Topical rescue of eumelanin synthesis, previously achieved in “redhaired” Mc1r-deficient mice, demonstrated significant ...

Multispectral Laser‐Scanning Photoacoustic Microscopy With SRS‐Generated Wavelengths for Skin Chromophore Characterization

Journal of Biophotonics, Volume 19, Issue 1, January 2026.
Unmixed maps showing vascular oxygen saturation (sO2), relative collagen, and relative melanin distributions. Maps were extracted from multispectral imaging of B6 and SKH1 Nude mouse abdominal skin using the proposed MS‐LS‐PAM system. ABSTRACT We present a single pump‐source, multispectral laser‐scanning photoacoustic microscopy (MS‐LS‐PAM) platform ...

Effect of the MC1R gene on sexual dimorphism in melanin-based colorations. [PDF]

, 2015
Variants of the melanocortin-1 receptor (MC1R) gene result in abrupt, naturally selected colour morphs. These genetic variants may differentially affect sexual dimorphism if one morph is naturally selected in the two sexes but another morph is naturally ...

Radiative Relaxation Quantum Yields for Synthetic Eumelanin^¶

Photochemistry and Photobiology, 2004
ABSTRACTWe report absolute values for the radiative relaxation quantum yield of synthetic eumelanin as a function of excitation energy. These values were determined by correcting for pump beam attenuation and emission reabsorption in both eumelanin samples and fluorescein standards over a large range of concentrations.

International Expert Consensus on Defining Skin of Color and Delivering Equitable Dermatologic Care

International Journal of Dermatology, Volume 65, Issue 1, Page 28-40, January 2026.
Gaps in dermatologic care for patients with skin of color (SOC), impacts and strategies to promote inclusivity. ABSTRACT Dermatological practice faces significant challenges in meeting the needs of populations with skin of color (SOC). Patients with SOC face disparities, including misdiagnoses and inequitable treatment outcomes.
