Light isomerizes the chromophore of rhodopsin, 11-cis retinal (formerly retinene), to the all-trans configuration. This introduces a succession of unstable intermediates—pre-lumirhodopsin,… Expand
THE MOLAR EXTINCTION OF RHODOPSIN
The molar extinction of rhodopsin is 40,600 cm.2 per mole equivalent of retinene; i.e., this is the extinction of a solution of rhodopsin which is produced by, or yields on bleaching, a molar… Expand
Visual Pigments in Single Rods and Cones of the Human Retina
Difference spectra of the visual pigments have been measured in single rods and cones of a parafoveal region of the human retina. Rods display an absorption maximum (λmax) at about 505 m� associated… Expand
The evolving role of strategic management development
- P. Brown
- 1 March 2005
Purpose – To validate conceptual frameworks for strategic management development. Also, to test the hypothesis that the objectives and design of a strategic management development programme need to… Expand
Rhodopsin rotates in the visual receptor membrane.

Dichroism can be photoinduced in a frog retina once it has been fixed with glutaraldehyde. This dichroism is absent in the normal retina because rhodopsin is free to undergo rotational Brownian… Expand
Detection of light‐induced changes of intracellular ionized calcium concentration in Limulus ventral photoreceptors using arsenazo III
1. The metallochromic indicator dye, arsenazo III, was injected intracellularly into Limulus ventral photoreceptor cells to concentrations greater than 1 m M.
The iodopsin system found in the cones of the chicken retina is identical with the rhodopsin system in its carotenoids. It differs only in the protein—the opsin —with which carotenoid combines. The… Expand

The transforming growth factor-ss superfamily cytokine macrophage inhibitory cytokine-1 is present in high concentrations in the serum of pregnant women.
Macrophage inhibitory cytokine-1 (MIC-1) is a recently described divergent member of the transforming growth factor-ss superfamily. MIC-1 transcription up-regulation is associated with macrophage… Expand
