Partial quantification of pigments extracted from the zooxanthellate octocoral Sinularia flexibilis at varying irradiances [PDF]
, 2010 Chlorophyll-a (chl-a) and carotenoid pigments of the zooxanthellate octocoral Sinularia flexibilis were analyzed using high performance liquid chromatography following exposure to three light intensities for over 30 days. From the coral fragments located

Bat eyes have ultraviolet-sensitive cone photoreceptors [PDF]
, 2009 Mammalian retinae have rod photoreceptors for night vision and cone photoreceptors for daylight and colour vision. For colour discrimination, most mammals possess two cone populations with two visual pigments (opsins) that have absorption maxima at short

Spectral tuning and deactivation kinetics of marine mammal melanopsins.
PLoS ONE, 2021 In mammals, the photopigment melanopsin (Opn4) is found in a subset of retinal ganglion cells that serve light detection for circadian photoentrainment and pupil constriction (i.e., mydriasis).

Adult limbal neurosphere cells: a potential autologous cell resource for retinal cell generation [PDF]
, 2014 The Corneal limbus is a readily accessible region at the front of the eye, separating the cornea and sclera. Neural colonies (neurospheres) can be generated from adult corneal limbus in vitro.

Absorption Spectra of the LWS Pigments Evaluated by the Dark–Light Difference Spectra
, 2013 The LWS pigments were reconstituted from (A) H allele with A1 retinal, (B) L allele with A1 retinal, (C) H allele with A2 retinal, and (D) L allele with A2 retinal. The λmax values are indicated with their standard errors.

Stabilization of the retinal vascular network by reciprocal feedback between blood vessels and astrocytes [PDF]
, 2005 Development of the retinal vasculature is controlled by a hierarchy of interactions among retinal neurons, astrocytes and blood vessels. Retinal neurons release platelet-derived growth factor (PDGFA) to stimulate proliferation of astrocytes, which in ...

Retinal-Based Proton Pumping in the Near Infrared
, 2017 Proteorhodopsin (PR) and Gloeobacter rhodopsin (GR) are retinal-based light-driven proton pumps that absorb visible light (maxima at 520–540 nm). Shifting the action spectra of these proton pumps beyond 700 nm would generate new prospects in optogenetics,
