Parameters for velocity-pCa fits to the Hill equation.
| VNTF | pCa50 | n |
|---|---|---|
| Control | 6.34 ± 0.07 | 1.89 ± 0.48 |
| IR2 | 6.47 ± 0.13 | 1.27 ± 0.42 |
| IDNR | 6.57 ± 0.04* | 3.46 ± 1.00 |
VNTF indicates native thin filament velocities for filaments isolated from non-ischemic control, ischemia followed by 2 h of reperfusion (IR2) and Ischemia followed by failed resuscitation (IDNR) Values represent mean ± SEM.
*
Indicates significantly (p < 0.05) different from control tissue. The tissue was obtained from one animal for each condition. The data represent the average actin filament velocities from 20 to 30 s videos from control, 19 from IR2 and 16 from IDNR.
