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 ...

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 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.

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 ...

On the elastic membrane in a potential flow
International Journal for Numerical Methods in Engineering, 1998This paper describes a method to reduce the errors of combined calculations of flow and structure. A FEM problem-orientated mesh consisting of improved finite elements is combined with a cosine-spaced vortex lattice. The method is called quasi-continuous-continuous because the discrete forces of the vortex lattice method are transformed into a ...

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 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.
