Sentences with phrase «calcium release»

Many intracellular sensors of events like calcium release have been made using fluorescent resonance energy transfer (FRET) probes.
cardiomyocytes exhibit decreased peak shortening and maximal velocity of shortening / relengthening, prolonged time - to - 90 % relengthening, reduced intracellular calcium release upon electrical stimulus associated with a slowed intracellular calcium decay rate, and significantly higher oxygen levelse, and significantly higher oxygen levels
