    • Caracterización del daño mecánico de la aorta en condición de hipoxia. Modelamiento y simulación numérica ... 
      Bezmalinovic Colleoni, Alejandro Slavo; Rivera, Eugenio; García Herrera, Claudio Moisés; Celentano, Diego Javier; González Candia, Alejandro Antonio; Herrera, Emilio A. (Univ Fed Rio de Janeiro, Brazil, 2021)
      Para evaluar de manera fidedigna el riesgo de ruptura de la aorta – junto a los índices de peligrosidad de enfermedades cardiovasculares u otras condiciones extremas y los efectos de posibles tratamientos – se requiere conocer ...
    • Developmental programming of cardiovascular dysfunction by prenatal hypoxia and oxidative stress 
      Giussani, Dino A.; Camm, Emily J.; Niu, Youguo; Richter, Hans G.; Blanco, Carlos E.; Gottschalk, Rachel; Blake, E. Zachary; Horder, Katy A.; Thakor, Avnesh S.; Hansell, Jeremy A.; Kane, Andrew D.; Wooding, F. B.Peter; Cross, Christine M.; Herrera, Emilio A. (2012)
      Fetal hypoxia is a common complication of pregnancy. It has been shown to programme cardiac and endothelial dysfunction in the offspring in adult life. However, the mechanisms via which this occurs remain elusive, precluding ...
    • Evolving in thin air-Lessons from the llama fetus in the altiplano 
      Llanos Mansilla, Jorge; Riquelme, Raquel A.; Herrera, Emilio A.; Ebensperger Darrouy, Germán; Krause, Bernardo; Reyes, Roberto V.; Sanhueza, Emilia M.; Pulgar, Víctor M.; Behn, Claus; Cabello, Gertrudis; Parer, Julian T.; Giussani, Dino A.; Blanco, Carlos E.; Hanson, Mark A. (2007)
      Compared with lowland species, fetal life for mammalian species whose mothers live in high altitude is demanding. For instance, fetal llamas have to cope with the low fetal arterial PO2 of all species, but also the likely ...
    • Long-term exposure to high-altitude chronic hypoxia during gestation induces neonatal pulmonary hypertension ... 
      Herrera, Emilio A.; Riquelme, Raquel A.; Ebensperger Darrouy, Germán; Reyes, Roberto V.; Ulloa, César E.; Cabello, Gertrudis; Krause, Bernardo J.; Parer, Julian T.; Giussani, Dino A.; Llanos Mansilla, Jorge (2010)
      We determined whether postnatal pulmonary hypertension induced by 70% of pregnancy at high altitude (HA) persists once the offspring return to sea level and investigated pulmonary vascular mechanisms operating under these ...
    • Melatonin and vitamin C increase umbilical blood flow via nitric oxide-dependent mechanisms 
      Thakor, Avnesh S.; Herrera, Emilio A.; Serón Ferré, María; Giussani, Dino A. (2010)
      Inadequate umbilical blood flow leads to intrauterine growth restriction, a major killer in perinatal medicine today. Nitric oxide (NO) is important in the maintenance of umbilical blood flow, and antioxidants increase NO ...
    • Role of the α-adrenergic system in femoral vascular reactivity in neonatal llamas and sheep: A comparative ... 
      Moraga, Fernando A.; Reyes, Roberto V.; Herrera, Emilio A.; Riquelme, Raquel A.; Ebensperger Darrouy, Germán; Pulgar, Víctor M.; Parer, Julian T.; Giussani, Dino A.; Llanos Mansilla, Jorge (2011)
      Using an integrative approach at the whole animal, isolated vessels, and molecular levels, we tested the hypothesis that the llama, a species that undergoes pregnancy under the influence of the chronic hypoxia of high ...
    • Toward an integrative understanding of social behavior: New models and new opportunities 
      Blumstein, Daniel T.; Ebensperger, Luis A.; Hayes, Loren D.; Vásquez Salfate, Rodrigo; Ahern, Todd H.; Burger, Joseph Robert; Dolezal, Adam G.; Dosmann, Andy; González-Mariscal, Gabriela; Harris, Breanna N.; Herrera, Emilio A.; Lacey, Eileen A.; Mateo, Jill; McGraw, Lisa A (2010)
      Social interactions among conspecifics are a fundamental and adaptively significant component of the biology of numerous species. Such interactions give rise to group living as well as many of the complex forms of cooperation ...
    • Ω3 supplementation and intermittent hypobaric hypoxia induce cardioprotection enhancing antioxidant mechanisms ... 
      Herrera, Emilio A.; Farías, Jorge G.; González Candia, Alejandro; Short, Stefania E.; Carrasco Pozo, Catalina; Castillo, Rodrigo L. (MDPI, 2015)
      Intermittent hypobaric hypoxia (IH) is linked with oxidative stress, impairing cardiac function. However, early IH also activate cardio-protective mechanisms. Omega 3 fatty acids (Ω3) induce cardioprotection by reducing ...
