How Much Pigment Should Flowers Have? Flowers With Moderate Pigmentation Have Highest Color Contrast

open access: yesFrontiers in Ecology and Evolution, 2021
Floral pigments are a core component of flower colors, but how much pigment a flower should have to yield a strong visual signal to pollinators is unknown.

Can Multispectral Dermoscopy Help In Distinguishing Blue Color?

open access: yesDermatology Practical & Conceptual, 2023
Introduction: The interpretation of colors is essential in the dermoscopic evaluation of skin lesions. The same blue color on white dermoscopy may indicate blood or pigment deep in the dermis.

A new pigment to be used in combination with zinc dust in zinc-rich anti-corrosive paints [PDF]

open access: yes, 1998
Zinc-rich paints (ZRP) are considered to be an important technological development for corrosion protection. The percentage of zinc corroded during the cathodic protection stage of zinc-rich coatings is relatively small in comparison with the initial ...

Amorphous silica: Prepared by byproduct microsilica in the ferrosilicon production and applied in amorphous silica-TiO2 composite with favorable pigment properties

open access: yesJournal of Materials Research and Technology, 2023
In order to improve the output value of microsilica produced during the ferrosilicon production process as well as to reduce pollution, amorphous silica was prepared from microsilica by calcination, alkali leaching and acid precipitation.

High-performance liquid chromatography of tetrapyrrole pigments [PDF]

open access: yesJournal of Chromatography A, 1978
Abstract Complex mixtures of pheophytins esterified with different C-20 diterpene alcohols have been separated by high-performance liquid chromatography in a reversed-phase system. The isomers of some monomeric and dimeric biliverdins have also been studied. Analytical and semi-preparative work is reported.

Candidate gene study of macular response to supplemental lutein and zeaxanthin. [PDF]

open access: yes, 2013
Supplementation with carotenoids is proposed to protect against age-related macular degeneration. There is, however, considerable variability in retinal macular pigment response, which may be due to underlying genetic variation. The purpose of this study

The Genetic and Evolutionary Drives behind Primate Color Vision

open access: yesFrontiers in Ecology and Evolution, 2017
Primate color vision is based on two to three cone types in the retina, each expressing a different class of visual pigment, making them the only mammals that possess trichromacy.

Efficacy of smartphone applications in high‐risk pigmented lesions [PDF]

open access: yesAustralasian Journal of Dermatology, 2017
AbstractBackground/ObjectivesMelanoma apps are smartphone applications that assess risk of pigmented lesions using a smartphone camera and underlying algorithm. We aimed to assess the capability of melanoma smartphone applications (apps) in making clinical decisions about risk, compared with lesion assessment by specialist trained dermatologists ...
