Forces Determining Ion Permeation

I would like to address two key issues related to the Perspectives on Ion Permeation . The first is the estimate of the size of the physical forces relevant for ion transport. Any good physical model of ion permeation requires the identification of the dominant forces. The second subject concerns a careful definition of the terms “mean field” and “mean field approximation.” Several articles in ...

Letter to the Editor Ion Permeation and Chemical Kinetics

The difficulties with and controversies surrounding the interpretation of electrophysiological data were highlighted in the recent Perspectives on Ion Permeation through membrane-spanning channels. The main issue was whether such data are more appropriately analyzed within the framework of chemical kinetics (Eyring’s Transition State Theory; Eyring, 1935) or the continuum electrodiffusional app...

Dear Editor,

  I read with interest Dr. Yazdani's reply about the article entitled “administration of magnesium sulfate to women with premature labor: The effect on bleeding time”.1 In my review of hematology references, I could not find any reference for determining hemoglobin (Hb) sooner than 24 hrs and Dr. Yazdani had not cited any reference either. However, about the influence of Hb on homeostasis, ther...
