  • Propagation malfunctions due to gap junction dysregulation 

    Rodríguez Cantalapiedra, Inma; Peñaranda Ayllón, Angelina; Echebarría Domínguez, Blas (2014)
    Comunicació de congrés
    Accés obert
    Gap junctions are membrane channels that connect the cytoplasm of adjacent cells allowing the cell-to-cell electrical coupling necessary for action potential propagation. Pathological conditions, such as malformations in ...
  • Multilevel analysis of calcium dynamics in stimulated cultures of cardiomyocytes 

    Vallmitjana Lees, Alex; Hove-Madsen, Leif; Barriga, Montserrat; Benítez Iglesias, Raúl (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We present an automatic method to characterize calcium activity in a culture of cardiac cells from a sequence of microscopy fluorescence images. The approach quantifies both the response of each individual cell in the ...
  • Study of a system to generate electricity on the Moon's surface during the lunar night 

    Torroba, Oscar; Climent, Blai; González Cinca, Ricardo; Ramachandran, Narayanan; Griffin, Michael D. (2012)

  • Nonlinearities due to refractoriness in SR Ca release 

    Peñaranda Ayllón, Angelina; Álvarez Lacalle, Enrique; Rodríguez Cantalapiedra, Inma; Hove-Madsen, Leif; Echebarría Domínguez, Blas (2012)
    Comunicació de congrés

    Calcium alternans is a pro-arrhytmic cardiac dysfunction related to beat-to-beat changes in the amplitude of intracellular calcium transient, that typically occurs at rapid pacing rates. Although oscillations in sarcoplasmic ...
  • Slow pulse due to calcium current induces phase-2 reentry in heterogeneous tissue 

    Peñaranda Ayllón, Angelina; Rodríguez Cantalapiedra, Inma; Echebarría Domínguez, Blas (2010)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Phase-2 reentry is a basic mechanism for the transition to VT and VF in the heart. It is thought to underly many causes of idiopathic ventricular arrhythmias as, for instance, those occurring in Brugada syndrome. ...
  • Calcium alternans produced by increased sarcoplasmic reticulum refractoriness 

    Rodríguez Cantalapiedra, Inma; Lugo, Carlos; Peñaranda Ayllón, Angelina; Echebarría Domínguez, Blas (IEEE Computer Society Publications, 2011)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Despite the important role of electro-mechanical alternans in cardiac arrhythmogenesis, its molecular origin is not well understood. In this paper we want to study alternans that can be associated with alternations in ...
