Depolarizing Neuromuscular Block
Anesthesiology, 1971Simultaneous 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, 1965RECENTLY 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.

Depolarization synthesis: understanding the optics of Mueller matrix depolarization
Journal of the Optical Society of America A, 2013In 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.

The effect of ketamine upon depolarizing and non-depolarizing neuromuscular blockade in rabbit
Naunyn-Schmiedeberg's Archives of Pharmacology, 1974The 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 IPSPs and depolarization by GABA of rat neostriatum cells in vitro
Experimental Brain Research, 1982In 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.

SPIE Proceedings, 2005
Several single-valued metrics have been introduced for the assessment of depolarization including the Depolarization Index and the Average Degree of Polarization (obtained by averaging the exiting degree of polarization over all incident polarization states). These metrics are compared then a more complete representation of depolarization is introduced,

Rotating depolarizer ellipsometry
Applied Optics, 1977We 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.

Journal of the Optical Society of America, 1951
Up to the present time no image-forming depolarizing filter has been described which will work for monochromatic light. This paper describes a simple monochromatic depolarizer. This depolarizer consists of two variable wave plates whose axes are separated by an angle of 45°. The retardation of the first wave plate varies from zero to 2π.

Succinylcholine: A Depolarizing Relaxant
Archives of Pediatrics & Adolescent Medicine, 1987Sir .—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 ...

Retrofit Cathodic Protection Design for Depolarized and Partially Depolarized Structure
CORROSION 2005, 2005Abstract Experiments were performed whereby steel specimens in natural sea water were successively cathodically polarized, depolarized or partially depolarized, and then repolarized to simulate the life cycle and retrofit of a galvanic cathodic protection (cp) system on space-frame type offshore structures.
