Ionic Components of Electric Current at Rat Corneal Wounds
BACKGROUND Endogenous electric fields and currents occur naturally at wounds and are a strong signal guiding cell migration into the wound to promote healing. Many cells involved in wound healing respond to small physiological electric fields in vitro. It has long been assumed that wound electric fields are produced by passive ion leakage from damaged tissue. Could these fields be actively main...
متن کاملIonic currents and ion fluxes in Neurospora crassa hyphae.
Voltage dependence of ionic currents and ion fluxes in a walled, turgor-regulating cell were measured in Neurospora crassa. The hyphal morphology of the model organism Neurospora simplifies cable analysis of ionic currents to determine current density for quantitative comparisons with ion fluxes. The ion fluxes were measured directly and non-invasively with self-referencing ion-selective microe...
متن کاملElectric Current Wound Healing
The authors review the existing physical modalities for treatment of chronic wounds and show the advantages of electric current and electromagnetic field stimulation. Direct currents, low frequency pulsed currents, monophasic high voltage pulses and pulsed electromagnetic fields are compared in respect of their efficiency. Wound healing quantification methods, wound healing dynamics and prognos...
متن کاملLarge currents generate cardiac Ca2+ sparks.
Previous models of cardiac Ca2+ sparks have assumed that Ca2+ currents through the Ca2+ release units (CRUs) were approximately 1-2 pA, producing sparks with peak fluorescence ratio (F/F(0)) of approximately 2.0 and a full-width at half maximum (FWHM) of approximately 1 microm. Here, we present actual Ca2+ sparks with peak F/F(0) of >6 and a FWHM of approximately 2 microm, and a mathematical mo...
متن کاملElectric currents in infinite networks
In this survey, we will present the basic facts about conduction in infinite networks. This survey is based on the work of Flanders [5, 6], Zemanian [17], and Thomassen [14], who developed the theory of infinite networks from scratch. Here we will show how to get a more complete theory by paralleling the well-developed theory of conduction on open Riemann surfaces. Like Flanders and Thomassen, ...
