ADDITIONS AND CORRECTIONS Volume 46, No. 19 Measurements of the Effective Diffusion Coefficient of Oxygen in Pancreatic Islets. E. S. Avgoustiniatos, K. E. Dionne, D. F. Wilson, M. L. Yarmush, and C. K. Colton* Page 6157. In the Abstract, the units for oxygen permeability (RtDt) mistakenly appear as “mol/(cm mmHg s)”; they should be “mol/(cm mm Hg s)”. Pages 6158-6162. Because of a production error, the typical pressure units of “mm Hg” were erroneously changed to simply “Hg”. These editing errors appear in the following sections: “Extraction of Kinetic and Diffusion Parameters” (four instances in the first subsection, and six instances in the second subsection); “Results” (four times in the second subsection and once in the final column heading in Table 1); and “Discussion” (pressures are given twice, near the end of the section). The table below indicates the correct appearance for the affected units: parameter

published units

correct units

pressure, p Km solubility coefficient of oxygen in tissue, Rt solubility coefficient of oxygen in medium, Rm oxygen permeability in tissue, RtDt

Hg Hg mol/(cm3 Hg)

mm Hg mm Hg mol/(cm3 mm Hg)

mol/(cm3 Hg)

mol/(cm3 mm Hg)

mol/(cm Hg s)

mol/(cm mm Hg s)

Please note that the pressure units (mm Hg) mentioned in the last paragraph of the “Experimental Procedures” section (page 6158) are correct as published. The staff at Industrial and Engineering Chemistry Research deeply apologize to the authors and readers for the inconvenience that these production errors have caused.
