    • Carbon monoxide: a novel pulmonary artery vasodilator in neonatal llamas of the Andean altiplano 
      Herrera Videla, Emilio; Reyes, Roberto V.; Giussani, Dino A.; Riquelme González, Raquel; Sanhueza Reinoso, Emilia; Ebensperger Darrouy, Germán; Casanello, Paola; Méndez, Natalia; Ebensperger, Renato; Sepúlveda Kattan, Esteban; Pulgar, Víctor M.; Cabello, Gertrudis; Blanco, Carlos E.; Hanson, Mark A.; Parer, Julian T.; Llanos Mansilla, Jorge (European Society of Cardiology, 2008)
      Aims To study the nitric oxide (NO) and carbon monoxide roles in the regulation of the pulmonary circulation in lowland and highland newborn sheep and llamas. Methods and results We used neonatal sheep (Ovis aries) and ...
    • Cardiovascular function in term fetal sheep conceived, gestated and studied in the hypobaric hypoxia of the ... 
      Herrera Videla, Emilio; Rojas, Rodrigo T.; Krause, Bernardo J.; Ebensperger Darrouy, Germán; Reyes, Roberto V.; Giussani, Dino A.; Parer, Julian T.; Llanos Mansilla, Jorge (WILEY-BLACKWELL, 2016)
      High-altitude hypoxia causes intrauterine growth restriction and cardiovascular programming. However, adult humans and animals that have evolved at altitude show certain protection against the effects of chronic hypoxia. ...
    • Cinaciguat (BAY-582667) modifies cardiopulmonary and systemic circulation in chronically hypoxic and pulmonary ... 
      Beñaldo Fuentes, Felipe Augusto; Araya Quijada, Claudio Enrique; Ebensperger Darrouy, Germán; Herrera Videla, Emilio Augusto; Reyes, Roberto V.; Moraga, Fernando A.; Riquelme Herrera, Alexander Nathan; González Candia, Alejandro; Castillo Galán, Sebastián; Valenzuela, Guillermo J.; Serón Ferré, María Josefa; Llanos, Aníbal J. (Frontiers Media, 2022)
      Neonatal pulmonary hypertension (NPHT) is produced by sustained pulmonary vasoconstriction and increased vascular remodeling. Soluble guanylyl cyclase (sGC) participates in signaling pathways that induce vascular vasodilation ...
    • High-altitude chronic hypoxia during gestation and after birth modifies cardiovascular responses in newborn sheep 
      Herrera Videla, Emilio; Pulgar, Víctor M.; Riquelme González, Raquel; Sanhueza Reinoso, Emilia; Reyes, Roberto V.; Ebensperger Darrouy, Germán; Parer, Julian T.; Valdéz, Enrique A.; Giussani, Dino A.; Blanco, Carlos E.; Hanson, Mark A.; Llanos Mansilla, Jorge (AMER PHYSIOLOGICAL SOC, 2007-06)
      Perinatal exposure to chronic hypoxia induces sustained pulmonary hypertension and structural and functional changes in both pulmonary and systemic vascular beds. The aim of this study was to analyze consequences of ...
    • Melatonin improves cerebrovascular function and decreases oxidative stress in chronically hypoxic lambs 
      Herrera Videla, Emilio; Macchiavello, Roberto; Montt, Camilo; Ebensperger Darrouy, Germán; Díaz Navarrete, Marcela; Ramírez, Santiago; Parer, Julian T.; Serrón Ferré, María; Reyes, Roberto V.; Llanos Mansilla, Jorge (John Wiley & Sons Ltd,, 2014)
      Chronic hypoxia during gestation and delivery results in oxidative stress and cerebrovascular dysfunction in the neonate. We assessed whether melatonin, a potent antioxidant and potential vasodilator, improves the cerebral ...
    • Melatonin reduces oxidative stress in the right ventricle of newborn sheep gestated under chronic hypoxia 
      González Candia, Alejandro Antonio; Arias, Pamela V.; Aguilar, Simón A.; Figueroa, Esteban G.; Reyes, Roberto V.; Ebensperger Darrouy, Germán; Llanos, Aníbal J.; Herrera Videla, Emilio Augusto (MDPI, 2021)
      Pulmonary arterial hypertension of newborns (PAHN) constitutes a critical condition involving both severe cardiac remodeling and right ventricle dysfunction. One main cause of this condition is perinatal hypoxia and oxidative ...
    • Sildenafil Reverses Hypoxic Pulmonary Hypertension in Highland and Lowland Newborn Sheep 
      Herrera Videla, Emilio; Ebensperger Darrouy, Germán; Krause, Bernardo; Riquelme González, Raquel; Reyes, Roberto V.; Capetillo, María; González, Sergio; Parer, Julian T.; Llanos Mansilla, Jorge (International Pediatric Research Foundation, Inc., 2008)
      Perinatal exposure to chronic hypoxia induces sustained hypertension and structural and functional changes in the pulmonary vascular bed. We hypothesized that highland newborn lambs (HLNB, 3600 m) have a higher pulmonary ...
    • Store-operated channels in the pulmonary circulation of high- and low-altitude neonatal lambs 
      Parrau, Daniela; Ebensperger Darrouy, Germán; Herrera Videla, Emilio; Moraga, Fernando; Riquelme González, Raquel; Ulloa, César E.; Rojas, Rodrigo T.; Silva, Pablo; Hernández, Ismael; Ferrada, Javiera; Díaz Navarrete, Marcela; Parer, Marcela; Cabello, Gertrudis; Llanos Mansilla, Jorge; Reyes, Roberto V.
