The men's pace was mundane until the leading pack was reduced after 20 miles.
For example, at 25 μM BPA, maximum pacing frequency was reduced from 15 Hz to 12.8 Hz.
While the level of Myocd mRNA expression was reduced following pacing, Pitx2 and Tbx5 remained statistically unchanged between control and paced groups.
Interestingly, in a small study of dogs with pacing induced heart failure, CFR was reduced with progression of heart failure, but coronary endothelial function was preserved until a late stage of heart failure [ 28].
After 6 hours of pacing, however, Cx43 immunosignal area was reduced specifically at the endocardial region of the LV free wall (6.76 ± 0.60%) in comparison to the endocardium of sham-paced controls (p < 0.05), without a detectable change in epicardial Cx43 signal (6.41 ± 0.30%; Figure 2C and 2D and Figure 2M; data are from n = 6 sham and 6 paced hearts).
In PLM3SA mice, expression of Na/K ATPase was increased and PLM decreased such that net Na/K pump current under quiescent conditions was unchanged (cf. WT myocytes); [Na+]i was increased and forward-mode Na/Ca exchanger was reduced in paced PLM3SA myocytes.
Early after the onset of pacing, the [5-C]glutamate/[2-C]pyruvate ratio was reduced by 51%, to 2.1 ± 0.6%, and stayed at this level throughout disease progression (P < 0.05).
Following his injury, he could not reach his former speed and was reduced to medium pace.
Contractile function was reduced with increasing pacing frequency indicated by significant 'freq' main effects (P<0.001 in Table 4).
As seen in Figure 5F, diastolic sarcomere length was reduced with increasing pacing frequency in both groups and significantly more so in the HG without Zn2+.
Similar results occurred at the shallower depths except that the number of species was reduced at a faster pace.
