Interaction between brain L-type calcium channels and alpha(2)-adrenoceptors in the inhibition of sodium appetite
(Elsevier B.V., 2002-03-22)
Calcium channels mediate the actions of many drugs. The present work investigated whether diltiazem, an L-type calcium channel blocker, alters the inhibition of sodium appetite induced by noradrenaline and the alpha(2)-a ...
Recording gamma band oscillations in pedunculopontine nucleus neurons
(JoVE, 2016-09)
Synaptic efferents from the PPN are known to modulate the neuronal activity of several intralaminar thalamic regions (e.g., the centrolateral/ parafascicular; Cl/Pf nucleus). The activation of either the PPN or Cl/Pf nuclei ...

Effect of amyotrophic lateral sclerosis serum on calcium channels related to spontaneous acetylcholine release
(Elsevier Ireland, 2002-12)
Objectives: The aim of this work was to further investigate the effect of sera from sporadic amyotrophic lateral sclerosis (ALS) patients on miniature end-plate potentials (MEPP) frequency, by the mouse passive transfer ...
Relaxation evoked by extracellular Ca(2+) in rat aorta is nerve-independent and involves sarcoplasmic reticulum and L-type Ca(2+) channell
(ELSEVIER SCIENCE INC, 2009)
The perivascular nerve network expresses a Ca(2+) receptor that is activated by high extracellular Ca(2+) concentrations and causes vasorelaxation in resistance arteries. We have verified the influence of perivascular nerve ...

Correlation between charge movement and ionic current during slow inactivation in Shaker K+ channels
(ROCKEFELLER UNIV PRESS, 1997-11)
Prolonged depolarization induces a slow inactivation process in some Ki channels. We have studied ionic and gating currents during long depolarizations in the mutant Shaker H4-Delta(6-46) K+ channel and in the nonconducting ...
Expression and characterization of LTx2, a neurotoxin from Lasiodora sp effecting on calcium channels
(ELSEVIER SCIENCE INC, 2008)
Here, we described the expression and characterization of the recombinant toxin LTx2, which was previously isolated from the venomous cDNA library of a Brazilian spider, Lasiodora sp. (Mygalomorphae, Theraphosidae). The ...
A Independência da Escolha dos Canais de Marketing nas Rendas dos Produtores Orgânicos Americanos2
(Sociedade Brasileira de Economia e Sociologia Rural, 2017)
One of the issues related to strategies for capturing value in organic production activities is the decision regarding the appropriate product distribution channel. The literature points out the importance of analyzing the ...
