Membrane depolarization is a critical component of neural signaling; in recent years there also has been a great deal of evidence that membrane depolarization can regulate neural gene expression. Therefore, excitatory neurotransmission may be an important mechanism of neural plasticity. We have investigated the intracellular pathways and DNA regulatory elements through which membrane depolariza...
Background and Objective: A deficiency of the enzyme pseudo cholinesterase (PChE) leads to slow hydrolysis of drugs having choline ester structure such as succinylcholine. The patients with this enzymatic disturbance should be provided long-term mechanical ventilation support until the return of normal muscle tonicity. Case presentation: The current study was performed on two female patients w...
Dopamine neurons in freely moving rats often fire behaviorally relevant high-frequency bursts, but depolarization block limits the maximum steady firing rate of dopamine neurons in vitro to ∼10 Hz. Using a reduced model that faithfully reproduces the sodium current measured in these neurons, we show that adding an additional slow component of sodium channel inactivation, recently observed in th...
In Arabidopsis suspension cells a rapid plasma membrane depolarization is triggered by abscisic acid (ABA). Activation of anion channels was shown to be a component leading to this ABA-induced plasma membrane depolarization. Using experiments employing combined voltage clamping, continuous measurement of extracellular pH, we examined whether plasma membrane H(+)-ATPases could also be involved i...
Almost all of the depolarization papers in the lidar literature employ a physically inappropriate notation and they use a definition of the depolarization ratio that is not linear in the quantity of interest. This depolarization lidar legacy is misleading and confusing. In particular, subscripts meaning parallel and perpendicular do not apply to atmospheric parameters, such as the volume backsc...
