Spontaneous activity of the light-dependent channel irreversibly induced in excised patches from Limulus ventral photoreceptors
(Springer-Verlag, 1992)
We have studied the properties of membrane patches excised from the transducing lobe of Limulus ventral photoreceptors. If patches are excised into an "internal" solution that resembles the ionic composition of the cytoplasm, ...
Actividad rítmica espontánea en vasos de placenta humana: ¿Un marcapaso fisiológico en los vasos sanguíneos?
(Sociedad Médica de Santiago, 2001)
ROLE OF CA2+-DEPENDENT K-CHANNELS IN THE MEMBRANE-POTENTIAL AND CONTRACTILITY OF AORTA FROM SPONTANEOUSLY HYPERTENSIVE RATS
(Stockton Press, 1994-11-01)
1 Contractile responses to KCl and membrane potentials were determined in aortic rings from spontaneously hypertensive rats (SHR), normotensive Wistar rats (NWR) and Wistar Kyoto rats (WKY) both in the absence and in the ...
Metabolism regulates the spontaneous firing of substantia nigra pars reticulata neurons via KATP and nonselective cation channels
(Society for Neuroscience, 2014-12-03)
Neurons use glucose to fuel glycolysis and provide substrates for mitochondrial respiration, but neurons can also use alternative fuels that bypass glycolysis and feed directly into mitochondria. To determine whether ...
THE RELATION BETWEEN THE AXON INITIAL SEGMENT WITH SPONTANEOUS AND DRIVEN FIRING OF SUBSTANTIA NIGRA DOPAMINERGIC NEURONSThe relatión between the axon initial segment with spontaneous and driven firing of substantia nigra dopaminergic neurons
(2017)
The axonal region most proximal to soma is the axon initial segment. This region is enriched in voltage-gated sodium channels as well as scaffolding proteins such as ankyrin-G, which allow to this structure to initiate ...
Diverse levels of an inwardly rectifying potassium conductance generate heterogeneous neuronal behavior in a population of dorsal cochlear nucleus pyramidal neurons
(AMER PHYSIOLOGICAL SOCBETHESDA, 2012)
Leao RM, Li S, Doiron B, Tzounopoulos T. Diverse levels of an inwardly rectifying potassium conductance generate heterogeneous neuronal behavior in a population of dorsal cochlear nucleus pyramidal neurons. J Neurophysiol ...
Novel model of calcium and inositol 1,4,5-trisphosphate regulation of InsP3 receptor channel gating in native endoplasmic reticulum
(Sociedad de Biología de Chile, 2004)
Coordinated gating of TRP-dependent channels in rhabdomeral membranes from Drosophila retinas
(Society for Neuroscience, 2000)
Using a newly developed dissociation procedure, we isolated the specialized rhabdomeral membranes from Drosophila retinal photoreceptors. From these membranes, we have recorded spontaneous active currents in excised patch, ...
Upregulation of intermediate calcium-activated potassium channels counterbalance the impaired endothelium-dependent vasodilation in stroke-prone spontaneously hypertensive rats
(ELSEVIER SCIENCE INC, 2009)
Endothelial dysfunction has been linked to a decrease in nitric oxide (NO) bioavailability and attenuated endothelium-derived hyperpolarizing factor (EDHF)-mediated relaxation. The small (SK(Ca)) and intermediate (IK(Ca)) ...
