    • Chemoreflex and endocrine components of cardiovascular responses to acute hypoxemia in the llama fetus 
      Giussani, Dino A.; Riquelme, Raquel A.; Moraga, Fernando A.; McGarrigle, Hugh H.G.; Gaete, Cristián R.; Sanhueza, Emilia M.; Hanson, Mark A.; Llanos Mansilla, Jorge (1996)
      We tested the hypothesis that the llama fetus has a blunted cardiovascular chemoreflex response to hypoxemia by investigating the effects of acute hypoxemia on perfusion pressure, heart rate, and the distribution of the ...
    • Nitric oxide synthase activity in brain tissues from llama fetuses submitted to hypoxemia 
      Galleguillos, Marco; Valenzuela Pedevila, María Antonieta; Riquelme González, Raquel; Sanhueza, Emilia M.; Sánchez, Gina; Figueroa, Jorge P.; Llanos Mansilla, Jorge (ELSEVIER SCIENCE INC, 2001-06)
      The fetal llama (Lama glama; a species adapted to live in chronic hypoxia in the highlands of the Andes) did not increase cerebral blood flow and reduce the brain oxygen uptake during hypoxemia. Although nitric oxide (NO) ...
    • Regional brain blood flow and cerebral hemispheric oxygen consumption during acute hypoxaemia in the Ilama fetus 
      Llanos Mansilla, Jorge; Riquelme, Raquel A.; Sanhueza, Emilia M.; Herrera Videla, Emilio; Cabello, Gertrudis; Giussani, Dino A.; Parer, Julian T. (2002)
      Unlike fetal animals of lowland species, the llama fetus does not increase its cerebral blood flow during an episode of acute hypoxaemia. This study tested the hypothesis that the fetal llama brain maintains cerebral ...
    • The role of neuropeptide Y in the ovine fetal cardiovascular response to reduced oxygenation 
      Sanhueza, Emilia M.; Johansen-Bibby, Anja A.; Fletcher, A. J W; Riquelme, Raquel A.; Daniels, Alejandro J.; Serón Ferré, María; Gaete, Cristián R.; Carrasco, Jorge E.; Llanos Mansilla, Jorge; Giussani, Dino A. (2003)
      This study investigated the role of neuropeptide Y (NPY) in mediating cardiovascular responses to reduced oxygenation in the late gestation ovine fetus by: (1) comparing the effects on the cardiovascular system of an ...
