Cardiac remodeling and arrhythmogenesis are ameliorated by administration of Cx43 mimetic peptide Gap27 in heart failure rats
Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; Lucero, Claudia M.; Toledo, Camilo; Díaz, Hugo S.; Pereyra, Katherin V.; Díaz-Jara, Esteban; Schwarz, Karla G.; Marcus, Noah J.; Retamal, Mauricio A.; Quintanilla, Rodrigo A.; Del Río, Rodrigo (Springer Nature, 2020)Alterations in connexins and specifically in 43 isoform (Cx43) in the heart have been associated with a high incidence of arrhythmogenesis and sudden death in several cardiac diseases. We propose to determine salutary ... -
Heart rate variability alterations in infants with spontaneous hypertonia
Andrade, David C. [Univ Mayor, Ctr Invest Fisiol Ejercicio, Santiago, Chile]; Arce-Alvarez, Alexis; Melipillan, Claudia; Toledo, Camilo; Marcus, Noah J.; Del Rio, Rodrigo (NATURE PUBLISHING GROUP, 2019)BACKGROUND: Hypertonia is characterized by increased resting muscle tone. Previous studies have shown that adult patients with hypertonia displayed autonomic imbalance. However, cardiac sympathovagal control in infants ... -
Revisiting the physiological effects of exercise training on autonomic regulation and chemoreflex control in heart failure: does ejection fraction matter?
Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Santiago, Chile]; Arce-Alvarez, Alexis; Toledo, Camilo; Díaz, Hugo S.; Lucero, Claudia; Quintanilla, Rodrigo A.; Schultz, Harold D.; Marcus, Noah J.; Amann, Markus; Del Rio, Rodrigo (AMER PHYSIOLOGICAL SOC, 2018)Heart failure (HF) is a global public health problem that, independent of its etiology [reduced (HFrEF) or preserved ejection fraction (HFpEF)], is characterized by functional impairments of cardiac function, chemoreflex ... -
Ventilatory and Autonomic Regulation in Sleep Apnea Syndrome: A Potential Protective Role for Erythropoietin?
Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Santiago, Chile]; Haine, Liasmine; Toledo, Camilo; Díaz, Hugo S.; Quintanilla, Rodrigo A.; Marcus, Noah J.; Iturriaga, Rodrigo; Richalet, Jean-Paul; Voituron, Nicolás; Del Rio, Rodrigo (FRONTIERS MEDIA SA, 2018)Obstructive sleep apnea (OSA) is the most common form of sleep disordered breathing and is associated with wide array of cardiovascular morbidities. It has been proposed that during OSA, the respiratory control center (RCC) ...
