Alexander disease is a fatal neurodegenerative disorder resulting from missense mutations of the intermediate filament protein, GFAP. The pathological hallmark of this disease is the formation of… Expand
Dynamical Mechanism for Subcellular Alternans in Cardiac Myocytes
Rationale: Cardiac repolarization alternans is an arrhythmogenic rhythm disturbance, manifested in individual myocytes as a beat-to-beat alternation of action potential durations and intracellular… Expand
MinK-dependent internalization of the IKs potassium channel.
AIMS KCNQ1-MinK potassium channel complexes (4alpha:2beta stoichiometry) generate IKs, the slowly activating human cardiac ventricular repolarization current. The MinK ancillary subunit slows KCNQ1… Expand
Non-Linear Dynamics of Cardiac Alternans: Subcellular to Tissue-Level Mechanisms of Arrhythmia
Cardiac repolarization alternans is a rhythm disturbance of the heart in which rapid stimulation elicits a beat-to-beat alternation in the duration of action potentials and magnitude of intracellular… Expand

4D Flow MRI has been used to quantify normal and deranged left ventricular blood flow characteristics on the basis of functionally distinct flow components. However, the application of this technique… Expand
Genetic modifiers of the Kvβ2‐null phenotype in mice
Shaker‐type potassium (K+) channels are composed of pore‐forming α subunits associated with cytoplasmic β subunits. Kvβ2 is the predominant Kvβ subunit in the mammalian nervous system, but its… Expand
Extra-cardiac manifestations of adult congenital heart disease.
Advancement in correction or palliation of congenital cardiac lesions has greatly improved the lifespan of congenital heart disease patients, resulting in a rapidly growing adult congenital heart… Expand

A 54-year-old man with nonischemic cardiomyopathy and recurrent ventricular tachycardia (VT) refractory to quinidine, sotalol, mexiletine, and amiodarone; 4 prior ablation procedures; and bilateral… Expand
Mechanism and magnitude of bipolar electrogram directional sensitivity: characterizing underlying determinants of bipolar amplitude.
BACKGROUND The amplitude of bipolar electrograms (EGMs) is directionally sensitive, decreasing when measured from electrode pairs oriented oblique to a propagating wavefront. OBJECTIVE Use… Expand
