Desarrollo de un sistema de clamp de tensión para el registro de potenciales trans-epiteliales en cámara de Ussing
(Universidad Autónoma de OccidenteIngeniería Electrónica y TelecomunicacionesDepartamento de Automática y ElectrónicaFacultad de Ingeniería, 2020-11-27)
El clamp de tensión es una técnica empleada en el campo de la electrofisiología, para realizar el estudio del comportamiento de los canales iónicos. El estudio de estos canales es de vital importancia dentro del campo ...
Potassium current in mature bovine spermatozoa
(INFORMA HEALTHCARE, 2008)
Ion channels have been assigned a pivotal importance in various sperm functions and are therefore promising targets for contraceptive development. The lack of data on channel functionality and pharmacology has hampered ...
Arachidonic acid activation of BKCa (Slo1) channels associated to the β1-subunit in human vascular smooth muscle cells
(Springer, 2013-12-05)
Arachidonic acid (AA) is a polyunsaturated fatty acid involved in a complex network of cell signaling. It is well known that this fatty acid can directly modulate several cellular target structures, among them, ion channels. ...
CAROTID CHEMOSENSORY NEURONS IN THE PETROSAL GANGLIA ARE EXCITED BY ACH AND ATP
(KLUWER ACADEMIC PUBLISHERS, 2003)
Several molecules have been proposed as excitatory transmitters between carotid body (CB) glomus (type I) cells and petrosal ganglion (PG) neurons (Eyzaguirre and Zapata, 1984; Gonzalez et al. 1994). Recently, experiments ...
Ion channels activated by light in Limulus ventral photoreceptors
(1986)
The light-activated conductance of Limulus ventral photoreceptors was studied using the patch-clamp technique. Channels (40 pS) were observed whose probability of opening was greatly increased by light. In some cells the ...
Properties of voltage-gated Ca2+ currents measured from mouse pancreatic beta-cells in situ
(SOCIEDAD BIOLGIA CHILE, 2006)
We used the single-microelectrode voltage-clamp technique to record ionic currents from pancreatic beta-cells within intact mouse islets of Langerhans at 37 degrees C, the typical preparation for studies of glucose-induced ...
