Spatiotemporal properties of high-speed calcium oscillations in the pedunculopontine nucleus
(American Physiological Society, 2013)
Investigation of the Effects of a1-Adrenoceptor Antagonism and L-Type Calcium Channel Blockade on Ejaculation and Vas Deferens and Seminal Vesicle Contractility In Vitro
(Wiley-Blackwell, 2012-01-01)
Introduction. Premature ejaculation is one of the most common male sexual dysfunctions. Current pharmacological treatments involve reduction in penile sensitivity by local anesthetics or increase of ejaculatory threshold ...

Differential effects of beta 1 and beta 2 subunits on BK channel activity
(ROCKEFELLER UNIV PRESS, 2005-04)
High conductance, calcium- and voltage-activated potassium (BK) channels are widely expressed in mammals. In some tissues, the biophysical properties of BK channels are highly affected by coexpression of regulatory (beta) ...
L-Type calcium channels mediate water intake induced by angiotensin injection into median preoptic nucleus
(Elsevier B.V., 2006-04-01)
Calcium ions are widely accepted as critically important in responses of neurons to a stimulus. We have show previously the central involvement of angiotensin II (ANGII) in water intake. This study determined whether ...

Calcium dependence of ryanodine-sensitive calcium channels from brain cortex endoplasmic reticulum
(Elsevier B.V., 1996)
Endoplasmic reticulum vesicles isolated from rat brain cortex and fused with lipid bilayers displayed ryanodine-sensitive calcium channels, with three cytoplasmic calcium dependences. A: Channels (n = 5) stimulated by Ca2+ ...
Mechanism behind gamma band activity in the pedunculopontine nucleus
(Wiley, 2011-07)
The pedunculopontine nucleus (PPN), part of the reticular activating system, modulates waking and paradoxical sleep. During waking and paradoxical sleep, EEG responses are characterized by low-amplitude, high-frequency ...
Luteinizing hormone (LH) acts through PKA and PKC to modulate T-type calcium currents and intracellular calcium transients in mice Leydig cells
(CHURCHILL LIVINGSTONE, 2011)
LH increases the intracellular Ca(2+) concentration ([Ca(2+)](i)) in mice Leydig cells, in a process triggered by calcium influx through T-type Ca(2+) channels. Here we show that LH modulates both T-type Ca(2+) currents ...
