The eyes of crayfish were exposed to lights of known spectral composition, and the course of regeneration was followed in the dark by measuring the content of rhodopsin and metarhodopsin in single rhabdoms isolated at various times after the adaptation, using an assay that is based on the fluorescence of metarhodopsin. Complete recovery requires several days in the dark after intense adaptation...

A blue fluorescent RNA was applied to modular blue fluorescent RNA sensors, wherein a "recognition" event of the target molecule by the aptamer domain is transmitted through a "communication" module, to a "signaling" fluorescent RNA domain, which "lights up".

Reef-building corals inhabit high light environments and are dependent on photosynthetic endosymbiotic dinoflagellates for nutrition. While photoacclimation responses of the dinoflagellates to changes in illumination are well understood, host photoacclimation strategies are poorly known. This study investigated fluorescent protein expression in the shallow-water coral Acropora yongei during a 3...

During the L-malate production through CO2-fixing process by Schizophylium commune, a blue coloration was seldom seen. When the coloration occurred within 6days after inoculation, the malate production was markedly reduced, and at the same time the sugar consumption was somewhate lowered. The more earlier the colora tion occurred, the more marked was the decrease of L-malate pro duciton. The ad...

Abstract A new tool for seismic design is presented, called Yield Displacement Charts (YDC). As with its predecessors, the Point Spectra (YPS) and Frequency (YFS), YDC concept takes advantage of simple features yield displacement ( u y ), to use in a performance-based instead force-based period-dependent approach. self-contained comprehensive approach YPS YFS enabling novel aspect be introduced...

By comparing the published DNA sequences for (a) the genes encoding the human visual color pigments (red, green, and blue) with (b) the genes encoding human, bovine, and Drosophila rhodopsins, a phylogenetic tree for the mammalian pigment genes has been constructed. This evolutionary tree shows that the common ancestor of the visual color pigment genes diverged first from that of the rhodopsin ...
