Effects of cromakalim (BRL 34915) on potassium conductances in CA3 neurons of the guinea-pig hippocampus in vitro [PDF]

, 1989
The action of the potassium channel activator, cromakalim (BRL 34915), on membrane potential, input resistance and current-voltage-relationship of CA3 neurons in a slice preparation of the guinea-pig hippocampus was investigated by means of intracellular

Regulation of mitochondrial potassium BKCa channel by naringenin derivatives: application of a new cellular model

European Journal of Medicinal Chemistry Reports
Mitochondrial potassium (mitoK) channels play a crucial role in mitochondrial and cellular physiology. One of the best described mitoK channels is the mitochondrial large-conductance calcium-activated potassium (mitoBKCa) channel.

Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

Advanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

The structure of a voltage gated potassium channel

, 2010
Voltage gated potassium channels (Kv channels) are tetrameric ion channels, responsible for regulating the potassium component of the membrane potential in a large range of cell types ranging from mammalian excitable cells to bacteria. Attempts have been

Distinct Distribution Patterns of Potassium Channel Sub-Units in Somato-Dendritic Compartments of Neurons of the Medial Superior Olive

Frontiers in Cellular Neuroscience, 2019
Coincidence detector neurons of the medial superior olive (MSO) are sensitive to interaural time differences in the range of a few tens of microseconds. The biophysical basis for this remarkable acuity is a short integration time constant of the membrane,

Kv7 and Kv11 channels in myometrial regulation.

, 2013
Ion channels play a key role in defining myometrial contractility. Modulation of ion channel populations is proposed to underpin gestational changes in uterine contractility associated with the transition from uterine quiescence to active labour.
