    • Calcium Alternans is Due to an Order-Disorder Phase Transition in Cardiac Cells 

      Álvarez Lacalle, Enrique; Echebarría Domínguez, Blas; Spalding, Jon; Shiferaw, Yohannes (2015-03-12)
      Article
      Accés obert
      Electromechanical alternans is a beat-to-beat alternation in the strength of contraction of a cardiac cell, which can be caused by an instability of calcium cycling. Using a distributed model of subcellular calcium we show ...

    • Cardiac tissue engineering by electrical stimulation with subcutaneous and cardiac adipose-tissue derived progenitor cells (ATDPCs) 

      Bayés-Genís, Antoni; Llucià-Valldeperas, Aida; Sánchez Terrones, Benjamín; Soler-Botija, C.; Roura, S.; Prat-Vidal, C.; Gálvez-Montón, C.; Rosell Ferrer, Francisco Javier; Bragós Bardia, Ramon (Fundació 'La Caixa', 2011)

      A major challenge of cardiac tissue engineering is directing cells to establish the physiological structure and function of the myocardium being replaced. In native heart, pacing cells generate electrical stimuli that ...

    • Low density lipoproteins promote unstable calcium handling accompanied by reduced SERCA2 and connexin-40 expression in cardiomyocytes 

      Barriga, Montserrat; Cal, Roi; Cabello, Nuria; Llach, Anna; Vallmitjana Lees, Alexander; Benítez Iglesias, Raúl; Badimón, Lina; Cinca, J.; Llorente-Cortés, Vicenta; Hove-Madsen, Leif (2013-03-13)
      Article
      Accés obert
      The damaging effects of high plasma levels of cholesterol in the cardiovascular system are widely known, but little attention has been paid to direct effects on cardiomyocyte function. We therefore aimed at testing the ...

    • Stochastic coupled map model of subcellular calcium cycling in cardiac cells 

      Romero Castañeda, Luis; Álvarez Lacalle, Enrique; Shiferaw, Yohannes (Institute of Physics (IOP), 2019-02-01)
      Article
      Accés obert
      In this study, we analyze a nonlinear map model of intracellular calcium (Ca) and voltage in cardiac cells. In this model, Ca release from the sarcoplasmic reticulum (SR) occurs at spatially distributed dyadic junctions ...
