Soon, the other dancers join him on stage, their robotic movements synchronized to the beat of a heart, transitioning to classical music and a slower, more fluid choreography that hints at life and humanity's beginnings.
We saw that the capacity for PDC to oxidize pyruvate changed dramatically over just 1 week, with no contribution from anaplerosis, as the heart transitioned from compensated cardiomyopathy to decompensated DCM.
However, Scn5a+/− hearts transitioned to discordant alternans at significantly earlier (i.e., larger) BCLs than WT hearts (which, in fact, did not show discordant alternans at all).
Similarly, if results from all regions are pooled, the BCLs at which hearts transitioned from normal APs to concordant alternans in either WT or Scn5a+/− hearts were not significantly different, before or after drug.
Both WT and Scn5a+/− hearts transitioned to discordant alternans significantly earlier in the presence of flecainide (e.g., 92.6 ± 3.5 ms, P = 0.005, n = 8 for RV1 2 in Scn5a+/− hearts).
Figure 6, A C, shows the mean values of BCL at which hearts transitioned from normal APs to concordant alternans, and then to discordant alternans both before drug (A) and after flecainide (B) or quinidine (C).
In Arabidopsis, 250 EMB genes have been confirmed to be required for normal embryo development [ 39], with EMB175 displaying aberrant cell organization and undergoing morphological arrest before the globular-heart transition [ 38].
Black bears commonly elicit defensive posturing and high respiratory rates within seconds of being disturbed, with their hearts transitioning from the quiescent state of hibernation, to supporting bursts of activity [ 18].
