Eumelanin and pheomelanin are predominant pigments in bumblebee (Apidae: Bombus) pubescence [PDF]
, 2017 Background: Bumblebees (Hymenoptera: Apidae: Bombus) are well known for their important inter- and intra-specific variation in hair (or pubescence) color patterns, but the chemical nature of the pigments associated with these patterns is not fully ...

A Histopathological Exploration of the Madurella mycetomatis Grain [PDF]
, 2013 Although the Madurella mycetomatis grains seem to interfere with the host defense mechanisms and impede the antifungal drugs penetration, yet their histological features are not fully known and hence this study was set out to determine that.

Effect of Melanization on Thallus Microstructure in the Lichen Lobaria pulmonaria
Journal of Fungi, 2022 Lichens often grow in microhabitats where they experience severe abiotic stresses. Some species respond to high UV radiation by synthesizing dark brown melanic pigments in the upper cortex. However, unlike the melanized structures of non-lichenized fungi,

5,6-dihydroxyindole-2-carboxylic acid (DHICA): a First Principles Density-Functional Study
, 2004 We report first principles density functional calculations for 5,6-dihydroxyindole-2-carboxylic acid (DHICA) and several reduced forms. DHICA and 5,6-dihydroxyindole (DHI) are believed to be the basic building blocks of the eumelanins.

Studying grain color diversity in the barley collection of VIR
Труды по прикладной ботанике, генетике и селекции, 2022 Background. Dark color of barley grain (Hordeum vulgare L.) can be caused by the synthesis and accumulation of two types of polyphenolic pigments – anthocyanins and melanins, which perform important functions in plant life, participating in the ...

Adsorption of molybdenum by melanin [PDF]
Environmental Health and Preventive Medicine, 2019 Melanin is detectable in various sense organs including the skin in animals. It has been reported that melanin adsorbs toxic elements such as mercury, cadmium, and lead. In this study, we investigated the adsorption of molybdenum, which is widely recognized as a toxic element, by melanin.Molybdenum level of the mouse skin was measured by inductively ...
