Signaling properties of the human chemokine receptors CXCR4 and CXCR7 by cellular electric impedance measurements. [PDF]
PLoS ONE, 2017 The chemokine receptor 4 (CXCR4) and 7 (CXCR7) are G-protein-coupled receptors involved in various diseases including human cancer. As such, they have become important targets for therapeutic intervention.

ELECTRIC IMPEDANCE OF SUSPENSIONS OF SPHERES [PDF]
Journal of General Physiology, 1928 A general expression has been derived for the electric impedance of a suspension of spheres each having a homogeneous non-reactive interior and a thin surface layer with both resistance and reactance. The applications and limitations of impedance measurements on such suspensions are discussed.

ELECTRIC IMPEDANCE OF THE FROG EGG [PDF]
Journal of General Physiology, 1942 Electrical impedance measurements were made upon unfertilized and fertilized eggs of the leopard frog, Rana pipiens, over a frequency range of 0.05 to 10 kc. Average values of 170 ohm cm.2 were obtained for the plasma membrane resistance of the egg, 2.0 µf/cm.2 for the plasma membrane capacity, 86° for the phase angle of the membrane, and 570 ohm cm ...

High impedance analysis in recordings of deep brain stimulation surgery
Interdisciplinary Neurosurgery, 2021 Background: Deep brain stimulation (DBS) is used widely today to control many chronic neurological disorders including Parkinson's disease (PD). During surgical procedures, an electric lead wire is inserted to stimulate a specific target of the brain. In

Electrical impedance tomography [PDF]
Annals of Translational Medicine, 2018 Continuous assessment of respiratory status is one of the cornerstones of modern intensive care unit (ICU) monitoring systems. Electrical impedance tomography (EIT), although with some constraints, may play the lead as a new diagnostic and guiding tool for an adequate optimization of mechanical ventilation in critically ill patients.

Limitations of Electric Impedance Plethysmography [PDF]
Circulation Research, 1954 Electric impedance plethysmography has been offered as a substitute for mechanical plethysmography and would be particularly suitable for regions in which the mechanical method cannot be applied. A comparative investigation of mechanical and impedance plethysmograms, taken simultaneously from a finger or a forearm, revealed that, while the normal ...
