Exempel på pigment

• Spectral tuning of pigments underlying red-green color vision.

• Spectral tuning in salamander visual pigments studied with dihydroretinal chromophores.

• Two approaches have been implemented to generate spectral extinction functions for cone pigments.

• Thus, the question is not why hypopigmented animals have elevated thresholds compared to pigmented animals, but rather, what causes their reduction in rhodopsin expression?

• The supernatant was filtered in the presence of polyvinyl polypyrrolidone and activated carbon to eliminate pigments and polyphenols.

• Photosynthetic light-harvesting pigment-protein complexes : toward understanding how and why.

• Photoreceptors recover from pigment adaptation after replacement 11-cis retinal, supplied by pigment epithelial cells, regenerate the visual pigment, and quench opsin's activity.

• The apparent ordering of pigment layers was observed wherever figures overlapped.

• However, the retina shrank only by about 1% relative to the pigment epithelium, so this does not seem to be the case.

• A back-propagation neural network predicts absorption maxima of chimeric human red0green visual pigments.

• The text does not elaborate on the difference between mixtures of pigments and mixtures of spectral light.

• Another potential source of luminance-contrast contamination might have arisen due to the nonuniform distribution of macular pigment within the central macular region.

• Polymorphism in the number of genes encoding long-wavelength-sensitive cone pigments among males with normal color vision.

• Mutually exclusive expression of human red and green visual pigment-reporter transgenes occurs at high frequency in murine cone photoreceptors.

• In this paper we investigate the interrelationships between the mineralization, growth and sheath pigment production.
