The Subcellular Origin of Bioluminescence in Noctiluca miliaris
The light emitted by Noctiluca has its origin in 1 to 5 x 10(4) organelles ("microsources") which are scattered throughout the perivacuolar cytoplasm, and which appear to be the elementary functional units of bioluminescence. Microscopical techniques, image intensification, and microphotometry were employed in their investigation. Microsources are fluorescent, strongly phase-retarding, and rang...
متن کاملShort Communication Distribution of Ion Channels in the Membrane of the Dinoflagellate Noctiluca Miliaris
Noctiluca miliaris, a marine dinoflagellate, exhibits spontaneous flexion of its tentacle. The movement of the tentacle is always accompanied by perturbations of membrane potential, termed the 'tentacle regulating potentials' (TRPs) (Eckert and Sibaoka, 1967). Though the waveform of the TRPs is liable to variation, it consists of four successive basic components: (1) a Na-dependent depolarizing...
متن کاملCorrelation between membrane potential responses and tentacle movement in the dinoflagellate Noctiluca miliaris.
Membrane potential responses and tentacle movement of the marine dinoflagellate Noctiluca miliaris were recorded simultaneously and their time relationships were examined. The food-gathering tentacle of Noctiluca exhibited slow extension-flexion movements in association with the spontaneously recurring membrane potential responses termed the tentacle regulating potentials (TRPs). The flexion of...
متن کاملLupus miliaris disseminatus faciei*
Lupus miliaris disseminatus faciei is a rare inflammatory dermatosis of unknown etiology that primarily affects young adults. Clinically, it is characterized by an asymptomatic papular eruption mainly involving the central face, typically on and around the eyelids. Characteristic histopathological features include dermal epithelioid cell granulomas with central necrosis and surrounding lymphocy...
