Indocyanine green fluorescence (ICG) angiography of the choroid gives better visualization of the choroidal vessels than does fluorescein angiography. We found that the detachment of the pigment epithelium seems bigger on ICG than on fluorescein angiograms, and pigmented lesions are more clearly delineated.

The motile, unicellular green alga Heamatococcus has come into prominence in recent years as a possible candidate for mass production for its red pigment, astaxanthin. The present paper summarizes the available information on nomenclature, taxonomy, morphology, life cycle and ultra-structure, which have so far been left out of the many reviews on this interesting alga.

We estimate the mechanical properties of pigment-containing ultra-high-strength cement composites (UHSCCs) and pigment-induced changes in their physical via thermal X-ray diffraction analyses. Hydrates samples are analyzed using thermogravimetry. Additionally, change color expression with UHSCC age is examined Commission Internationale de l’ Éclairage L*a*b* analysis. Correlation analysis perfo...

Diversification of cone pigment spectral sensitivities during evolution is a prerequisite for the development of color vision. Previous studies have identified two naturally occurring mechanisms that produce variation among vertebrate pigments by red-shifting visual pigment absorbance: addition of hydroxyl groups to the putative chromophore binding pocket and binding of chloride to a putative e...

A green method for the synthesis of high-performance diketopyrrolopyrrole pigments using diethyl succinate in the presence of mixture of ionic liquids is reported. Although, alkaline condition is needed in the succinate ester route for synthesis of the pigments, in the present study, the replacement possibility of conventional organic base by mixture of BMIMOH and BMIMBF4 ionic liquids was inve...

PURPOSE This study sought to examine the in vitro interaction of human RPE cells with indocyanine green (ICG). The interaction between ICG and the RPE may have clinical relevance in the interpretation of clinical ICG angiography. METHOD Cultured primary human RPE cells were incubated with ICG. Infrared fluorescence microscopy was used to detect RPE cell ICG fluorescence. The proportions of ce...

PURPOSE To investigate the chemical toxicity of indocyanine green (ICG). METHODS Surface active and precipitating effects of ICG were quantitatively analyzed by determining bovine serum albumin dissolved or precipitated in the presence or absence of salt solutions. The effects of precipitation on serum and cytotoxicity were evaluated by measuring the viability of retinal pigment epithelium (R...

Ashford (1917) noted a faint greenish color in some of the colonies of cultures of Monilia albicars. No other reference to a green pigmentation of Monilia has been found in the literature. Of the 6 species of Monilia described by Martin, Jones, Yao and Lee (1937) and Jones and Martin (1938) it was noticed that Candida stellatoidea2 produced large amounts of green pigment. This was considered of...

The average opening rate of Vicia faba L. stomata was determined over an initial 20-minute light period following darkness. Nonsaturating intensities of broad band red and blue light had similar quantum effectiveness for the promotion of opening, whereas broad band green was about 40% and far red about 5% as effective. The opening rates under saturating red, green, and blue light were the same....
