  1. 24 wrz 2020 · Single-cell and single-nucleus RNA sequencing are used to construct a cellular atlas of the human heart that will aid further research into cardiac physiology and disease.

  2. 17 sie 2023 · The cardiac conduction system is a network of specialized cardiac muscle cells that initiate and transmit the electrical impulses responsible for the coordinated contractions of each cardiac cycle.

  3. 1 paź 2023 · Action potentials in ventricular myocytes trigger the calcium (Ca 2+) entry necessary for their contraction. Their synchronicity, characteristic shape and length all help protect these cells against abnormal electrical activity. When these protective mechanisms go wrong, it can be potentially life threatening.

  4. 19 lip 2024 · Key points. The modular structure of heart muscle and the organ-level synchrony of the heartbeat ensure tight reciprocal coupling between the myosin ATPase cycle and the macroscopic cardiac...

  5. 24 sie 2022 · SeisWind® 3D is an evolution of Fugros UUHR seismic service that consists of eight solid custom specification digital streamers, with proprietary sources and decimetre accuracy in-sea positioning systems.

  6. 5 kwi 2022 · This review summarizes known and emerging regulatory mechanisms connecting the human cardiomyocyte sarcomere to cell cycle regulation including structural and signaling mechanisms. Cardiac regeneration could be augmented through targeting the inhibitory effects of the sarcomere on cardiomyocyte proliferation.

  7. 3 lis 2020 · Wigger’s diagram demonstrating the components of the cardiac cycle. See here for a Flash animation. FRANK-STARLING LAW. The Frank–Starling law of the heart states that the stroke volume of the heart increases in response to an increase in the volume of blood filling the heart (the end diastolic volume) when all other factors remain constant.
