These input output hemodynamic models were estimated from beat-to-beat data of arterial blood pressure, end-tidal (hbox {CO}_2) and cerebral blood flow velocity measured at the middle cerebral arteries via transcranial Doppler.
Even after 4 weeks incubation with BI 2536 these cells continued normal beating (data not shown).
In this condition we also found that mesoderm formed robustly (as assessed by the expression of Brachyury), but that cardiac differentiation was severely impaired with only a small background of cells expressing the MHCα::GFP reporter and beating (data not shown).
The beat-to-beat data are resampled at 10 Hz to create a uniform timebase.
ICG has the potential to provide continuous (beat-to-beat) data which is less operator-dependent and (potentially) less influenced by patient factors such as body mass index (BMI).
The non-perfect correlation between ICG and echocardiography-derived HR values (R = 0.96-0.98) can be attributed to the different time periods (three consecutive cardiac cycles by echocardiography compared with a continuous measure of 60 seconds of beat-beat data from ICG).
Embryos injected with foxi1e MO did not 'drift' in the culture dish, a characteristic behaviour due to the beating of cilia, and fluorescent beads moved considerably slower over the surface of morphant embryos, suggesting abnormal ciliary beating (data not shown).
