MODIFICATIONS ON DOPAMINERGIC AND CHOLINERGIC SYSTEMS INDUCED BY THE WATER TANK TECHNIQUE - ANALYSIS THROUGH YAWNING BEHAVIOR
(Arch Int Pharmacodynamie, 1990-11-01)
Animals deprived of REM sleep by the water tank technique show an important decrease in frequency of yawning, induced by dopaminergic (apomorphine in low doses) and cholinergic (physostigmine and pilocarpine) agonists, if ...
Electroencephalogram in vitro and Cortical Transmembrane Potentials in the Turtle Chrysemys d’ Orbigny
(Karger Publishers, 1991)
An experimental stable model of an in vitro turtle brain (Chrysemys d'orbigny) was developed in order to compare electrographic activity (EEG) with transmembrane potentials. Two preparations were used: a whole intact ...
EFFECTS of STRESS ON DRUG-INDUCED YAWNING - CONSTANT VS INTERMITTENT STRESS
(Elsevier B.V., 1995-07-01)
Experiment 1 tested whether chronic exposure to immobilization, foot shock or forced swimming would result in suppression of apomorphine, pilocarpine-, and physostigmine-induced yawning. Immobilization caused suppression ...
Thin layer Chromatography-Autography-High resolution mass spectrometry analysis: accelerating the identification of Acetylcholinesterase inhibitors
(Wiley, 2015-11)
Introduction: The prevailing treatment for Alzheimer's disease is the use of acetylcholinesterase (AChE) inhibitors. Natural extracts are the principal source of AChE's inhibitors. However, their chemical complexity demands ...
Functional characterization of acetylcholine receptors and calcium signaling in rat testicular capsule contraction
(Elsevier B.V., 2013-08-15)
The motor activity of mammalian testicular capsule (TC) contributes to male fertility and infertility, but the acetylcholine receptors related to the contractions induced by cholinergic drugs are poorly known. Indeed to ...
Os ajustes termorregulatórios induzidos pela estimulação colinérgica central durante o exercício físico são mediados pelo barorreflexo arterial
(Universidade Federal de Minas GeraisUFMG, 2008-08-08)
The aim of this study was to evaluate if the effects of central cholinergic receptors stimulation on thermoregulation, in untrained rats during exercise, is mediated by arterial baroreceptors. The animals were anesthetized ...
Anticholinesterasic, Nematostatic and Anthelmintic Activities of Pyridinic and Pyrazinic Compounds
(Bentham Science Publ Ltd, 2011-08-01)
In the search for acetylcholinesterase inhibitors as a potential target for the discovery of anthelmintic drugs, a series of 27 pyridinic and pyrazinic compounds have been designed on the basis of molecular hybridization ...
