... far induced luminescence in two other ophiuroid species, Ophiopsila aranea and Ophiopsila californica. The aim of this work was thus to investigate the putative involvement of two biogenic amines, tryptamine and octopamine, in light emission of three ophiuroid species. A. filiformis responds to both...

... and digitonin stimulated luminescence in a Ca 2+ -dependent manner in the absence of mechanical stimulation. Mechanically sensitive luminescence was strongly inhibited by the intracellular Ca 2+ chelator BAPTA-AM[1,2-bis( o -aminophenoxy)ethane- N,N,N′,N′ -tetraacetic acid acetoxymethyl ester]; there was only...

...N. De Bremaeker; F. Baguet; M. C. Thorndyke; J. Mallefet ABSTRACT Amphipholis squamata is a polychromatic luminescent ophiuroid. The effects of amino acids ( γ-aminobutyric acid, GABA, taurine, glycine and glutamate), N -methyl-D-aspartate (NMDA) and the invertebrate neuropeptides Antho-RFamide...

... pretreatment modified the time course of the two phases of adrenaline-induced luminescence; an increase in oxygen consumption was observed during the fast phase of light production but a decrease occurred during the slow phase of luminescence. Pretreatment of isolated photophores with 5.5mmol l −1 glucose...

... radiobinding assays were developed to identify and characterize β-adrenergic binding in membrane preparations from this species, using the two β-antagonists [3H]dihydroalprenolol and [3H]CGP12177 as tracers. In addition, the effect of various β-adrenergic agents on luminescence was examined. Binding...

Crabs move away from luminescent and mechanical stimuli and this behavior is well correlated with the cardiac responses. Therefore, cardiac response ratios can be used...

...J. F. Rees; F. Baguet ABSTRACT Isolated photophores of the epipelagic fish Porichthys notatus become spontaneously luminescent after a few hours in saline at 20°C. This luminescence is not significantly affected by the adrenergic antagonists propranolol and phentolamine. The addition of glucose...

...B. Christophe; F. Baguet ABSTRACT A fast transient peak of light, followed by a slow luminescence, was produced by isolated photophores of Porichthys notatus when exposed to 1 m m -epinephrine, norepinephrine or phenylephrine, an α -adrenergic agonist. Only a slow luminescence was induced by 1 m m...
