Static Quark Potentials in Quantum Gravity [PDF]
, 1995 We present potentials between static charges from simulations of quantum gravity coupled to an SU(2) gauge field on $6^{3}\times 4$ and $8^{3}\times 4$ simplicial lattices.

Improved Lattice Actions with Chemical Potential [PDF]
Nucl.Phys. A642 (1998) 275-281, 1998 We give a prescription how to include a chemical potential \mu into a general lattice action. This inclusion does not cause any lattice artifacts. Hence its application to an improved - or even perfect - action at \mu =0 yields an improved resp. perfect action at arbitrary \mu.

Neonatal Guillain-Barre’ Syndrome
Pediatric Neurology Briefs, 1988 A term female infant presenting with generalized hypotonia, paucity of lower limb movements, and diminished DTRs was diagnosed as a case of Guillain-Barre’ syndrome at the Hospital for Sick Children, University of Toronto, Canada.

eLife, 2022 Back-propagating action potentials (bAPs) regulate synaptic plasticity by evoking voltage-dependent calcium influx throughout dendrites. Attenuation of bAP amplitude in distal dendritic compartments alters plasticity in a location-specific manner by ...

Modulation of neural cell membrane conductance by the herbal anxiolytic and antiepileptic drug aswal [PDF]
, 2000 To evaluate the effects of aswal on ionic fluxes and neuronal excitation, we performed extracellular and whole cell patch clamp recordings on CA1 pyramidal neurons of guinea pigs and Long-Evans rats.

American Journal of Physiology. Heart and Circulatory Physiology, 2011 Human-induced pluripotent stem cells (hiPSCs) can differentiate into functional cardiomyocytes; however, the electrophysiological properties of hiPSC-derived cardiomyocytes have yet to be fully characterized.

Action potential solitons and waves in axons [PDF]
arXiv, 2022 We show that the action potential signals generated inside axons are reaction-diffusion solitons or reaction-diffusion waves, refuting the Hodgkin and Huxley hypothesis that action potentials propagate along axons with an elastic wave mechanism. Reaction-diffusion action potential wavefronts and solitons annihilate at collision and boundaries of axons,

Potential biomarker of metformin action [PDF]
Journal of Endocrinology, 2014 Metformin is a first-line, anti-diabetic agent prescribed to over 150 million people worldwide. The main effect of metformin is to suppress glucose production in the liver; however, there is no reliable biomarker to assess the effectiveness of metformin administration. Our previous studies have shown that phosphorylation of CBP at S436 is important for

Intracellular Recording of Action Potentials by Nanopillar Electroporation
Nature Nanotechnology, 2012 Action potentials have a central role in the nervous system and in many cellular processes, notably those involving ion channels. The accurate measurement of action potentials requires efficient coupling between the cell membrane and the measuring ...

On the quadratic action of the Hawking-Turok instanton [PDF]
, 1998 Positive definiteness of the quadratic part of the action of the Hawking-Turok instanton is investigated. The Euclidean quadratic action for scalar perturbations is expressed in terms of a single gauge invariant quantity $q$. The mode functions satisfy a
