... cooled from 35 to 15°C. We measured heart ventricle mass, an indicator of O 2 delivery capacity, and mitochondrial respiration in permeabilized skeletal and cardiac muscle to elucidate associated changes in mitochondrial capacities at the cellular level. We examined animals on day 24 of incubation...

In addition, because cardiac tissue must sustain contractile activity even before birth, it may be more physiologically mature at birth...

...) and the systemic circuit via the left aorta (LAo), which continues as the coeliac artery (CA). The subpulmonary conus contains a muscular cog-wheel valve (CWV, made of cartilagenous teeth and surrounded by cardiac muscle), the contraction of which can occlude the entrance to the pulmonary artery. The right aorta...
