Properties of Calcium and Potassium Currents of Clonal Adrenocortical Cells
(1989)
The ionic currents of clonal Y-1 adrenocortical cells were studied using the whole-cell variant of the patch-clamp technique. These cells had two major current components: a large outward current carried by K ions, and a ...

Ionic currents in dispersed chemoreceptor cells of the mammalian carotid body
(1989)
Ionic currents of enzymatically dispersed type I and type II cells of the carotid body have been studied using the whole cell variant of the patch-clamp technique. Type II cells only have a tiny, slowly activating outward ...

Adaptación morfofuncional renal tras nefrectomía unilateral en el adulto
(1989-01-30)
En el presente estudio se analizaron los cambios morfológicos y funcionales del riñón remanente tras la nefrectomía de riñones con patología urológica crónica y baja función en el adulto. Los resultados obtenidos demuestran ...

Canales iónicos de neuronas septales aisladas: Caracterización electrofisiológica y modulación por TRH y LHRH
(1989-10-02)
El presente trabajo continua con una de las líneas de investigación de nuestro grupo que trata del estudio de las propiedades electrofisiológicas de neuronas del sistema nervioso central de mamíferos. Este estudio se inició ...

Currents recorded through small areas of squid axon membrane with an internal virtual ground voltage clamp
(1981)
A new voltage-clamp apparatus for the squid axon has been implemented to enable recording of currents through small areas of axon membrane. The performance of this clamp was tested by recording total sodium currents from ...

Effects of membrane depolarization and divalent-cations on anaphylactic histamine secretion
(1986)
The effects of membrane depolariz.ation and divalent cations on histamine release have been studied in sensitized mast cells. Membrane potential of these cells has been measured with intracellular microelectrodes. Our ...

Depolarizing response of rat parathyroid cells to divalent cations
(1983)
Membrane potentials were recorded from rat parathyroid glands continuously perfused in vitro. At 1 .5 mM external Ca", the resting potential averages -73 ± 5 mV (mean ± SD, n = 66). On exposure to 2.5 mM Ca", the cells ...

Low pO2 selectively inhibits K channel activity in chemoreceptor cells of the mammalian carotid body
(1989)
The hypothesis that changes in environmental O2 tension (pO2) could affect the ionic conductances of dissociated type I cells of the carotid body was tested. Cells were subjected to whole-cell patch clamp and ionic currents ...
