Photochemical and Photophysical Properties of Carotenoids and Reactive Oxygen Species: Contradictions Relating to Skin and Vision

Oxygen, 2023
Molecular mechanisms based on photo-physical processes involving dietary carotenoids, their radicals, and the role of oxygen are discussed and used to suggest explanations of the poorly understood and often contradictory results related to mainly skin ...

Identification of the yellow skin gene reveals a hybrid origin of the domestic chicken. [PDF]

PLoS Genetics, 2008
Yellow skin is an abundant phenotype among domestic chickens and is caused by a recessive allele (W*Y) that allows deposition of yellow carotenoids in the skin.

A Dunaliella salina Extract Counteracts Skin Aging under Intense Solar Irradiation Thanks to Its Antiglycation and Anti-Inflammatory Properties

Marine Drugs, 2022
Glycation, and the resulting buildup of advanced glycation end products (AGEs), is recognized as a key driver of cumulative skin damage and skin aging. Dunaliella salina is a halophile microalga adapted to intense solar radiation through the production ...

Reconstructing Carotenoid-Based and Structural Coloration in Fossil Skin [PDF]

Current Biology, 2016
Evidence of original coloration in fossils provides insights into the visual communication strategies used by ancient animals and the functional evolution of coloration over time [1-7]. Hitherto, all reconstructions of the colors of reptile integument and the plumage of fossil birds and feathered dinosaurs have been of melanin-based coloration [1-6 ...

The Detection of Carotenoid Pigments in Human Skin

Journal of Investigative Dermatology, 1975
Carotenoid pigments were extracted chemically from both epidermis and dermis obtained from non-carotenemic individuals at autopsy. Absorption maxima characteristic of beta-carotene were found in the extracts of specimens of epidermis following cantharidin application in volunteers made carotenemic by the ingestion of beta-carotene (180 mg/day for 10 ...

Non-Invasive Spectroscopic Determination of the Skin and Blood Carotenoids of Term and Preterm Infants in the First Month of Life and the Influence of Free Radical-Mediated Diseases

Life
Postpartum adaptation causes an increased formation of free radicals (FRs) in the organism, which can lead to development of various FR-mediated diseases (FRMDs) in the newborn.
