Melanins: Skin Pigments and Much More—Types, Structural Models, Biological Functions, and Formation Routes

open access: yes, 2014
This review presents a general view of all types of melanin in all types of organisms. Melanin is frequently considered just an animal cutaneous pigment and is treated separately from similar fungal or bacterial pigments.

Flavonoids and Melanins: A Common Strategy across Two Kingdoms

open access: yesInternational Journal on Biological Sciences, 2014
Ultraviolet (UV) radiations alter a number of metabolic functions in vivant. They produce damages to lipids, nucleic acids and proteins, generating reactive oxygen species such as singlet oxygen (O2), hydroxyl radical (HO) and superoxide anion (O2 ...

Locus coeruleus complex of the family Delphinidae [PDF]

open access: yes, 2018
The locus coeruleus (LC) is the largest catecholaminergic nucleus and extensively projects to widespread areas of the brain and spinal cord. The LC is the largest source of noradrenaline in the brain.

Near-Infrared Excited State Dynamics of Melanins: The Effects of Iron Content, Photo-Damage, Chemical Oxidation, and Aggregate Size

open access: yesJournal of Physical Chemistry A, 2014
Ultrafast pump–probe measurements can discriminate the two forms of melanin found in biological tissue (eumelanin and pheomelanin), which may be useful for diagnosing and grading melanoma.

Effects of Melanin-Induced Free Radicals on the Isolated Rat Peritoneal Mast Cells [PDF]

open access: yes, 1930
Pheomelanin from human red hair (RHM) produces considerably more cellular damage in Ehrlich ascites carcinoma cells when subjected to radiations of wavelength 320-700nm than eumelanin from black hair (BHM).
