(1) Analysis of conjugated discharges ACHs showed that they appeared predominantly periodically (87% of cases).
(2) By means of two monoclonal antibodies, which were directed against external and internal acetylcholine (ACh) receptor epitopes, we were able to visualize ACh-receptors on OHCs.
(3) At 100 microM-ACh the apparent open time became shorter probably due to channel blockade by ACh molecules.
(4) ACh released from the vesicular fraction was about 100-fold more than could be accounted for by miniature end-plate potentials; possible causes of this overestimate are discussed.
(5) The nature of the putative autoantigen in Graves' ophthalmopathy (Go) remains an enigma but the sequence similarity between thyroglobulin (Tg) and acetylcholinesterase (ACHE) provides a rationale for epitopes which are common to the thyroid gland and the eye orbit.
(6) The response selectivity, such as orientation and direction selectivities, of cortical cells was not affected by the depletion of ACh.
(7) Acetylcholine (ACh) induces a K+ current in rabbit cardiac Purkinje fibres.
(8) This paper examines the chiral nature of the covalent conjugates formed upon reaction of acetylcholinesterase (AchE) with enantiomeric cycloheptyl, isopropyl, and 3,3-dimethylbutyl methylphosphonyl thiocholines.
(9) The results suggest that AH5183 does not bind to the ACh transporter recognition site on the outside of the vesicle membrane, and thus it might inhibit allosterically.
(10) In the absence of prostigmine, increasing the concentration of ACh in the synaptic cleft did not change the time constant for decay of end-plate currents.
(11) We examined the effect of propentofylline on two adenosine actions in the rat hippocampus; the A2-mediated stimulation of 3H-cAMP accumulation and the A1-mediated inhibition of 3H-ACh release.
(12) Neuromuscular transmission and muscle sensitivity to acetylcholine (ACh) were studied in vitro in soleus and extensor digitorium longus (EDL) from 6 hr to 4 months after the injection of toxin.3.
(13) These results suggest that different molecular factors might mediate the effects on GABA and ACh synthesis.
(14) At the adult neuromuscular junction, acetylcholine (ACh) receptors are highly localized at the subsynaptic membrane, whereas, embryonic myotubes before innervation have receptors distributed over the entire surface.
(15) Nitric oxide (NO) induced tetrodotoxin-resistant NANC relaxation, similar to that induced by electrical stimulation or acetylcholine (ACh).
(16) In senescent rats, however, the proportions of salt-soluble and detergent-soluble AChE may differ from those in young rats.
(17) In addition, in these animals blood AChE and butyrylcholine esterase (BuChE) activities were determined.
(18) Roles of the LHA dopaminergic and cholinergic systems in CTS learning were investigated by electrophoretic application of dopamine (DA) and acetylcholine (ACh), and their antagonists.
(19) The absence of ACh therefore appears to reduce the cortical response to stimulation, while background activity values do not change.
(20) As stimulus rate was decreased, blockade of secretion resulted from fewer stimuli but no difference in ACh content was found between stimulated and unstimulated glands.
Smallage
Definition:
(n.) A biennial umbelliferous plant (Apium graveolens) native of the seacoats of Europe and Asia. When deprived of its acrid and even poisonous properties by cultivation, it becomes celery.
