A Melanin-Related Phenolic Polymer with Potent Photoprotective and Antioxidant Activities for Dermo-Cosmetic Applications

open access: yesAntioxidants, 2020
Eumelanins, the dark variant of skin pigments, are endowed with a remarkable antioxidant activity and well-recognized photoprotective properties that have been ascribed to pigment components derived from the biosynthetic precursor 5,6-dihydroxyindole-2 ...

Melanisation in Boreal Lichens Is Accompanied by Variable Changes in Non-Photochemical Quenching

open access: yesPlants, 2022
Lichens often grow in microhabitats where they absorb more light than they can use for fixing carbon, and this excess energy can cause the formation of harmful reactive oxygen species (ROS).

Quantitative scattering of melanin solutions [PDF]

open access: yes, 2005
The optical scattering coefficient of a dilute, well solubilised eumelanin solution has been accurately measured as a function of incident wavelength, and found to contribute less than 6% of the total optical attenuation between 210 and 325nm.

The First Homozygote Mutation c.499G>T (Asp167Tyr) in the RPE65 Gene Encoding Retinoid Isomerohydrolase Causing Retinal Dystrophy

open access: yesCurrent Issues in Molecular Biology, 2022
RPE65, an abundant membrane-associated protein present in the retinal pigment epithelium (RPE), is a vital retinoid isomerase necessary for regenerating 11-cis-retinaldehyde from all-trans retinol in the visual cycle.

SEARCH PRODUCERS OF POLYPHENOLS AND SOME PIGMENTS AMONG BASIDIOMYCETES [PDF]

open access: yesBiotechnologia Acta, 2014
General content of polyphenols, carotenoids and melanin in basidiomycetes carpophorus was determined. 50 species were studied, 27 of which belong to the Polyporales form and 23 are to the Agaricales form.

Chaga extracts and melanins after plasma treatment of raw material

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2019
The extracts and melanins of chaga (Inonotus obliquus (Pers.) Pil.) obtained by raw material pretreatment with high-frequency capacitive low-pressure plasma (RF-plasma) under different technological conditions were studied.

Mitogen-Activated Protein Kinase Cross-Talk Interaction Modulates the Production of Melanins in Aspergillus fumigatus

open access: yesmBio, 2019
Aspergillus fumigatus is the most important airborne human pathogenic fungus, causing thousands of deaths per year. Its lethality is due to late and often inaccurate diagnosis and the lack of efficient therapeutics.
