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=2fd/, using values for intercellular phase delay () 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.

MVO2 was calculated as the arterial-CS oxygen difference multiplied by mean CBF, and myocardial work (A) was estimated by the triple product (LV systolic pressure times LV dP/dt times heart rate, in millions). Both MVO2 and the triple product increased with exercise in a linear fashion (y=0.11x+5.1; R2=.96) in the normal state. . . . [Full Text of this Article]
