Quantitative Analysis of Membrane Potentials
Methods in molecular biology, 2009The changes that occur in electrochemical gradients across biological membranes provide us with invaluable information on physiological responses, pathophysiological processes and drug actions/toxicity. This chapter aims to provide researchers with sufficient information to carry out a quantitative assessment of mitochondrial energetics at a single ...

Membrane potential and Donnan potential
Biophysical Chemistry, 1988The Nernst-Planck-Poisson equations for the potential profile across a membrane are exactly solved without recourse to the assumption of constant field within the membrane. It is assumed that the membrane core of thickness dc is covered by a surface layer of thickness ds in which the membrane-fixed charges are distributed at a uniform density N.

Electrostatic potentials in membrane systems [PDF]
Bulletin of Mathematical Biology, 1983 A membrane with an arbitrary distribution of fixed charges inside and on its surfaces is considered. A procedure for calculating the local electrostatic potential at an arbitrary point of the system is described and its validity discussed. This procedure is based on the linearization of the 3-dimensional Poisson-Boltzmann equation around an exact 1 ...

Membrane potential of bipolar membranes
Journal of Electroanalytical Chemistry, 1996Abstract The membrane potential of a bipolar membrane composed of a cation-exchange layer in series with an anion-exchange layer is analyzed theoretically and experimentally. The theoretical approach is based on an extension of the Nernst-Planck equations of monopolar charged membranes to the case of the two ion-exchange layers in series and the ...

Synthetic chloride channel regulates cell membrane potentials and voltage-gated calcium channels.
Journal of the American Chemical Society, 2009Synthetic ion channels are of great interest in mimicking the biological functions of natural ion channels. Although many synthetic ion channels could selectively mediate ion transport across lipid bilayer membranes, the biological roles played by these ...

The nucleus accumbens (NAc) is a forebrain area in the mesocorticolimbic dopamine (DA) system that regulates many aspects of drug addiction. Neuronal activity in the NAc is modulated by different subtypes of DA receptors.

The shifts in membrane potential, caused by the injection of D-glucose into a permeation cell, were obtained theoretically from membrane potential theory and compared to experimental data measured for immobilized (entrapped) glucose oxidase membrane and its lamellar enzyme membranes.

Classically, three classes of neurons in the cerebellar nuclei (CN), defined by different projection targets and content of transmitters, have been distinguished. However, evidence for different types of neurons based on different intrinsic properties is

Membrane potentials for keratin
Journal of Colloid Science, 1947Abstract Measurements of the membrane potentials of keratin membranes have been made using KCl and NaCl and the results show how the selectivity of the membranes can be altered by soaking in suitable buffer solutions. The results support Toerell's theory of membrane behavior in neutral salts, and some membrane potential measurements using HCl ...

The interactions of (macro-)molecules with biological membranes underlies much of cell biology. This paper outlines many of the factors that must be taken into account in order to understand fully the nature of these interactions.
