In the article by Ying et al, “Ca2+ waves in lung capillary endothelium” (Circ Res. 1996;79:898-908), on page 903, the paragraph headed “Wave Velocity” should read “We calculated a propagation velocity (v) of the intercellular Ca2+ wave of 5±2 μm/s (n=9) from the wave-velocity equation v=2πfd/Δθ, using values for intercellular phase delay (Δθ) of the dominant wave component at frequency f and internuclear distance d, between adjoining cells.” (Emphasis added.) Also, the first sentence of the legend for Figure 5 should read as follows: “Endothelial [Ca2+]i profiles for a single lung capillary are shown during periods of capillary perfusion with blood or with Ca2+-free dextran-Ringer (dextran in Ca2+-free buffer containing 0.5 mmol/L EGTA).” (Emphasis added.) The concentration was stated correctly in the text.
In the article by Bernstein et al, “Function and production of nitric oxide in the coronary circulation of the conscious dog during exercise” (Circ Res. 1996;79:840-848), on page 846, two x-axis labels for Figures 3 and 4 were omitted by printer error. The figures are correctly reproduced below.
