The authors would like to modify Equations (5a) and (5b) in Section 3.1. Cellular Solute Flux Equations of the published paper [1].

The authors regret printing errors and would like to highlight that these do not occur in the FORTRAN program generating the data of Table 1 and Figures 2–6, which are correctly reproduced in the published paper.

The correct equations read:

\begin{array}{l} J_{N a}^{l m, p u m p} = P_{N a, K}^{l m, p u m p} {(\frac{C_{N a}^{c}}{K_{N a}^{l m, p u m p} + C_{N a}^{c}})}^{3} {(\frac{C_{K}^{l i s}}{K_{K}^{l m, p u m p} + C_{K}^{l i s}})}^{2} [V^{l m} + E^{p u m p}] \\ J_{K}^{l m, p u m p} = - \frac{2}{3} J_{N a}^{l m, p u m p} \\ V_{m}^{l m} = ψ^{c e l l} - ψ^{l i s} \\ I_{N a}^{l m, p u m p} = \frac{F \cdot P_{N a, K}^{l m, p u m p}}{3} {(\frac{C_{N a}^{c}}{K_{N a}^{l m, p u m p} + C_{N a}^{c}})}^{3} {(\frac{C_{K}^{l i s}}{K_{K}^{l m, p u m p} + C_{K}^{l i s}})}^{2} [V^{l m} + E^{p u m p}] \end{array}

(5a)

where F is the Faraday constant. Introducing the pump conductance,

G^{l m, p u m p}

we have:

I_{N a}^{l m, p u m p} = G^{l m, p u m p} [V^{l m} + E^{p u m p}]

G^{l m, p u m p} = \frac{F \cdot P_{N a, K}^{l m, p u m p}}{3} {(\frac{C_{N a}^{c}}{K_{N a}^{l m, p u m p} + C_{N a}^{c}})}^{3} {(\frac{C_{K}^{l i s}}{K_{K}^{l m, p u m p} + C_{K}^{l i s}})}^{2}

(5b)

The dimension of

P_{N a, K}^{l m, p u m p}

is mol∙s⁻¹∙V⁻¹ and that of

G^{l m, p u m p}

is Siemens, both per unit area of apical membrane.

The authors apologize for any inconvenience caused and would like to state that their scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
