introduction: spreading depression (sd) is a propagating wave of depolarization followed by depression of the neuroglial activities and can modulate extracellular dopamine concentrations in the neocortex. it has been shown that the dopaminergic system plays a role in migraine. sd has been suggested as a critical phenomenon in the pathophysiology of migraine. the aim of this study was to investi...

iontophoresis of epinephrine for assessment of neuromuscular junction response is a new technique that can improve diagnose of neuromuscular dysfunction. the purpose of this study was to investigate the effects of iontophoresis of epinephrine on neuromuscular junction response. iontophoresis of epinephrine solution (1mg/ml), sodium chloride, calcium gluconate, epinephrine with sodium chloride a...

Above-bandgap femtosecond optical excitation of a ferroelectric/dielectric BaTiO3/CaTiO3 superlattice leads to structural responses that are consequence the screening strong electrostatic coupling between component layers. Time-resolved x-ray free-electron laser diffraction shows response includes net lattice expansion consistent with depolarization-field driven by photoexcited charge carriers....

Abstract When spin rotating devices are used in an electron accelerator ring the stochastic depolarization caused by synchrotron radiation becomes issue. Special design of optics is required order to minimize harmful effect depolarization. Ring adjustments which help called matching. In this lecture formalism for deriving matching conditions presented. Then, derived examples a rotator based on ...
