A dual function activity-dependent, muscle-specific enhancer from rat nicotinic acetylcholine receptor δ-subunit gene
(John Wiley & Sons, Inc., 1996-11)
Nicotinic acetylcholine receptors (nAChR) mediate communication between nerve and muscle. The expression of these receptors increases dramatically during muscle development when myoblasts are fusing into multinucleated ...
Histological localization of binding sites of [alpha]-bungarotoxin and of antibodies specific to acetylcholine receptor in goldfish optic nerve and tectum
(Elsevier, 1980-07-21)
Goldfish optic nerve as well as ganglion cell neurites grown in culture selectively bind rhodamine-labeled [alpha]-bungarotoxin following tissue fixation. Binding is competed for by unlabeled bungarotoxin, by carbamylcholine ...
A sequential double-label autoradiographic method that quantifies altered rates of regional glucose metabolism
(Elsevier, 1985-12-30)
An autoradiographic sequential double-label variant of the deoxyglucose method for measurement of local glucose utilization has been developed. This technique takes advantage of the short half-life of the positron emitter, ...
Ornithine decarboxylase activity in retinal explants of goldfish undergoing optic nerve regeneration
(Elsevier, 1981-06)
Retinal explants cultured in the presence of fetal calf serum (FCS) exhibit an increase in the activity of ornithine decarboxylase which is maximal several hours after explanation. The measured activity of this enzyme is ...
Inhibition of polyphosphoinositide phosphodiesterase by aminoglycoside antibiotics
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1985-08)
The calcium-activated phosphodiesteratic hydrolysis of 32 P-labeled phosphatidylinositol 4,5-bisphosphate and phosphatidylinositol 4-phosphate in prelabeled nerve ending membranes is inhibited by the aminoglycosides neomycin ...
Role for calcium from the sarcoplasmic reticulum in coupling muscle activity to nicotinic acetylcholine receptor gene expression in rat
(John Wiley & Sons, Inc., 1998-06-05)
Neurally evoked muscle electrical activity suppresses nicotinic acetylcholine receptor (nAChR) gene expression in extrajunctional domains of adult muscle fibers. It has been proposed that this regulation is mediated by ...
The role of the optic tectum in various visually mediated behaviors of goldfish
(Elsevier, 1977-06-17)
Five visually mediated behaviors were assessed following ablation of one or both lobes of the optic tectum in goldfish. Three of the behaviors disappeared following tectal ablations; optomotor response (swimming with the ...
Visual stimulation increases regional cerebral blood flow and metabolism in the goldfish
(Elsevier, 1979-01-26)
Studies with radioactive antipyrene and deoxyglucose indicate that both blood flow and metabolism are enhanced in the goldfish optic tectum following a brief visual stimulation. It is concluded that the brain of cold-blooded ...
Increased activity of ornithine decarboxylase in goldfish following optic nerve crush
(Elsevier, 1981-06)
Ornithine decarboxylase (ODC) activity increased in goldfish retina, brain, and kidney several days following unilateral intraorbital optic nerve crush. Activity in both retinas followed a similar time course, an elevation ...
Properties of endogenous, membrane-associated sialidase activity (N-acetylneuraminidase) of the goldfish visual system
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1983-01)
The endogenous sialidase (N-acetylneuraminidase) activity of membranes prepared from goldfish retina and optic tectum displays characteristics similar to those reported for neural plasma membrane sialidases of other ...
