Depolarizing Action of Endotoxin

Nature, 1965
RECENTLY we reported that various endotoxins induced hyper-reactivity of pulmonary vasoconstrictor mechanisms to circulating acetylcholine (ACh) in rabbits1,2. This effect was specific for ACh and was not due to inhibition of ACh-esterase. It was abolished by atropine but not by ganglionic blocking agents2.

The depolarizing GABA response

Canadian Journal of Physiology and Pharmacology, 1997
In some situations the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) elicits a hyperpolarizing response (H response) followed by a depolarizing response (D response) on cortical neurons. It has recently been established that the D response on hippocampal pyramidal cells is largely carried by bicarbonate ions (HCO3-).

Depolarization synthesis: understanding the optics of Mueller matrix depolarization

Journal of the Optical Society of America A, 2013
In this paper, we consider the forward problem in depolarization by optical systems. That is, we seek a compact parameterization that allows us to take an arbitrary "pure" optical system (namely one defined by a single Mueller-Jones matrix) and model all possible ways in which that system can depolarize light.

Depolarizing IPSPs and depolarization by GABA of rat neostriatum cells in vitro

Experimental Brain Research, 1982
In neostriatal slices pretreated with sodium pentobarbital (100 microM) and 4-aminopyridine (50 microM), intrastriatal stimulation elicited EPSPs followed by a slowly decaying depolarization which lasted about 200 ms and was associated with a membrane conductance increase and a suppression of spike potentials.

The effect of ketamine upon depolarizing and non-depolarizing neuromuscular blockade in rabbit

Naunyn-Schmiedeberg's Archives of Pharmacology, 1974
The interaction between ketamine and various neuromuscular blocking drugs is presently unclear. Therefore, experiments were carried out on rabbits to determine ketamine's effect upon the neuromuscular blockade produced by succinylcholine (SCh), d-tubocurarine (d-TC), pancuronium and a new short-acting drug, AH 8165, an azobis-arylimidazo-(1,2-a ...

Depolarizing the perceptual magnet effect

The Journal of the Acoustical Society of America, 1998
In recent years there has been a great deal of interest in demonstrations of the so-called “Perceptual-Magnet Effect” (PME). In these studies, AX-discrimination tasks purportedly reveal that discriminability of speech sounds from a single category varies with judged phonetic “goodness” of the sounds.

Depolarization bandwidth of fiber optic passive depolarizers

Optical Engineering, 2001
Several single-mode fiber optic applications benefit from the use of depolarized light. Examples are suppression of polarization hole burning (PHB) in erbium-doped fiber amplifiers (EDFA),1–3 reduction of polarization-dependent loss arising from fiber components (e.g., couplers and wave-division multiplexers),4 reduction of the signal fading in fiber ...

Rotating depolarizer ellipsometry

Applied Optics, 1977
We have built a fully automatic ellipsometer, which is spectroscopic and of the single rotating optical component type but which avoids two serious problems encountered in rotating analyzer ellipsometers.

Succinylcholine: A Depolarizing Relaxant

Archives of Pediatrics & Adolescent Medicine, 1987
Sir .—In the recent article concernin[ill] King's syndrome and malignant hype[ill] thermia (MH), 1 the authors noted tha[ill] MH is induced by "volatile anesthetic and/or nondepolarizing muscle relax[ill] ants, most often halothane and suc[ill] cinylcholine." While these two agent are classically associated with MH succinylcholine, rather than being ...

Neurotrophin Depolarization

Science's STKE, 2002
Neurotrophins are best known for their role in neuron survival and differentiation, effects that are mediated by kinase cascades activated by receptor tyrosine kinases. Brain-derived neurotrophic factor (BDNF) is also able to stimulate rapid depolarization through the activation of a Na + current ( I
