Research on depolarizing characteristics of a quartz depolarizer

2019 International Conference on Optical Instruments and Technology: Optical Systems and Modern Optoelectronic Instruments, 2020
A depolarizer is usually used to reduce the polarization response of the spectrometer. On the basis of LYOT depolarizer, a depolarizer composed of two quartz crystals with the same wedge angle is designed and developed. Based on the matrix optics theory, this paper studies the relationship between the residual polarization degree of a LYOT depolarizer ...

Depolarization-induced slow potentiation of depolarizing afterpotential

NeuroReport, 1997
Effects of strong membrane depolarization on the excitability of regular spiking (RS) non-pyramidal cells in layer VI of the cat motor cortex were examined in in vitro slice preparations. RS non-pyramidal cells that expressed depolarizing afterpotential (DAP) following spikes displayed either of the two distinct responses: immediate and successive ...

The Depolarization Effect of Wedge Depolarizer for Polychromatic Light

2011 Symposium on Photonics and Optoelectronics (SOPO), 2011
The wedge depolarizer was usually used as a depolarizer for monochromatic light, but the absolute monochromatic light is inexistent. In this paper, the depolarization effect of the depolarizer for polychromatic linearly polarized light with different spectrum types was discussed. The spectrum of incident light included Gauss, Lorentz and Rectangle. The

Depolarizing Neuromuscular Block

Anesthesiology, 1971
Simultaneous recording of tension output and intracellular potentials was made in rat diaphragms contracting isometrically. There were two types of responses to the administration of succinylcholine and decamethonium. An "initial" response characterized by: 1) transient increase in the strength of muscular contractions, 2) 5 to 10 mV depolarization of ...

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 ...
