Pigment-Pigment Interactions and Protein Dynamics in Light-Harvesting Complexes: a Single-Molecule Study
… that the electron-phonon coupling in the B800 pigment pool is very weak. In summary, this thesis demonstrates that low-temperature single-molecule spectroscopy provides a unique method to reveal details of pigment-pigment interactions in the weak to intermediate as well as strong coupling limit …

Carbachol-Induced Pigment Granule Dispersion
The retinal pigment epithelium (RPE) is a monolayer of pigmented, simple cuboidal epithelium with long apical processes that interdigitate with photoreceptors. In teleosts, the RPE aids in light adaptation through pigment granule movements. In the bright light, pigment granules are dispersed into …

Studies on the cone pigment, iodopsin
… have been found against iodopsin and other cone pigments in chicken retina: (1) specifically against iodopsin (cell line of 7D3); (2) against iodopsin and another cone pigment (cell lines of 2D4, 4G2, and 5E3); and (3) against iodopsin and other three cone pigments (cell line of 2C3). One …

Investigating determinants of macular pigment optical density and macular pigment distribution in adults aged 45--73: Can enhanced analytical techniques improve the ability to predict macular pigment status?
… dietary, sex, and biochemical factors to macular pigment optical density (MPOD) and macular pigment (MP) distribution in 108 adults. Dietary assessment tools were evaluated for their ability to predict MP status. Macular pigment was assessed at four foveal sites and one parafoveal site. An average …

Environmental Causes of Pigment Heterogeneity In Phytoplankton Species
… based on the presence of different types of pigments within each cell. Classifying phytoplankton species is important to understand biogeochemical cycles and the pelagic food chain system in the ocean, which could be manipulated by several environmental influences including nutrient …

The Transformation of Human Retinal Pigment Epithelial Cells
… blood-retinal barrier, and inflammation. Retinal pigment epithelial (RPE) cells, a single layer of cuboidal epithelium located at the back of eye behind neural retina, gain access and proliferate in the vitreous during PVR. RPE cells in the vitreous undergo epithelial-mesenchymal transformation …

SOLAR ENERGY HARVESTING WITH PHOTOSYNTHETIC PIGMENT-PROTEIN COMPLEXES
… Central to this process are the photosynthetic pigment-protein complexes that transduce sunlight into biologically useful forms of energy through a photochemical charge separation that has a quantum efficiency close to 100%. Integrating these natural pigment-protein complexes in bio-hybrid …

Studies on the Gecko P521 Cone-Type Pigment
In summary, mutational analysis and molecular approaches were used to identify components of the plant disease resistance pathway. The availability of the dnd mutants may facilitate further study of the control of HR cell death, gene-for-gene resistance, and broad spectrum disease resistance in …

Color vision: Studies on gecko cone visual pigment
Cone visual pigments are responsible for color vision. Although a large amount is known about rod pigments, relatively little is known about cone pigments. This thesis describes the identification and characterization of the photointermediates of gecko cone visual pigment P521: batho (ca. 570 nm), …

Localization of Cytoskeletal Elements in Teleost Retinal Pigment Epithelium
The G.3.5 antigen (Mr = 100,000) has been localized in brain, cerebellum, skeletal, cardiac, and smooth muscle tissues using the G.3.5 mAb, and has been described as an IFAP on the basis of its co-localization and co-isolation with desmin. Through biochemical analysis, the G.3.5 antigen was found …

Impact of macular pigment optical density on photophobia threshold
… they are collectively referred to as macular pigment (MP). By absorbing short-wavelength light, MP may attenuate photophobia (PP)---visual discomfort induced by normal light exposure---for targets composed of short-wavelength light. The aim of this study was twofold: first, to investigate a …

Pigment composition in heterotrophically and photoheterotrophically grown rhodopseudomonas capsulata
… purpose of this research was to investigate the pigment composition of and localisation within the photosynthetic bacterium Rhodopseudomonas capsulata grown aerobically heterotrophically, anaerobically photoheterotrophically and during transference bflween these two states. Nine carotenoids were …

Investigating red pigment production by Penicillium purpurogenum DSM 62866
The production of a diverse range of pigments with variable properties and application potential highlights filamentous fungi as potential sources of pigments in the consumer-driven move toward natural colourant alternatives in food, cosmetic and nutraceutical products. The majority of natural …

New tools for the discovery of pigment gene function
… genes contribute to the vast variation in human pigmentation. Many of these encode proteins that localize to the melanosome, the lysosome-related organelle that synthesizes pigment, but have unclear functions. Here, we describe the MelanoIP method for rapidly isolating melanosomes and profiling …

Evolution of Endothelin Signaling and Diversification of Adult Pigment Patterns
… which drive differences in adult morphology. Pigmentation is an especially tractable trait to study mechanisms of diversification in form. Fishes of the genus Danio exhibit diverse pigment patterns that serve as useful models for understanding the genes and cell behaviors underlying evolution …
