These findings were confirmed over a range of pacing rates, in low K+ concentration solutions, and in Scn5a+/Δ KPQ hearts used to model human long QT syndrome.
It then tests the resulting criteria over a range of pacing rates, and under conditions of altered QT interval in low K+ concentration ([K+]) solutions and in Scn5a+/Δ KPQ hearts modeling long QT syndrome.
The Mongols used an "ox-bow" machine to throw bolts which had been dipped in burning pitch, with a range of 2500 paces.
The isolated Ca2+ clock model has been previously investigated in detail (50) and produces a wide range of pacing rates suitable for the rabbit SAN cell model.
We put a range of machines through their paces looking for easy-to-use bits of kit that produced consistently good coffee.
After putting more than 30 cashback sites through their paces for a range of goods, consumer champion and TV money pundit Martin Lewis has come up with a list of top payers on his Moneysavingexpert.com site.
Here, we describe the use of machine learning to comprehensively analyze 17 functional parameters derived from force readouts of hPSC-derived ventricular cardiac tissue strips (hvCTS) electrically paced at a range of frequencies and exposed to a library of compounds.
Although circadian clocks use temperature compensation mechanisms to maintain the same pace over a range of temperatures, they are also capable of synchronizing to daily temperature cycles.
Nevertheless, both regular pacing through a range of frequencies and extrasystolic stimuli demonstrated a progressively increasing tendency to the development of non-sustained, then sustained, arrhythmogenesis, in isolated, Langendorff-perfused RyR2 p/s and RyR2 s/s but not WT hearts.
