  • Global REACH 2018: Andean highlanders, chronic mountain sickness and the integrative regulation of resting blood pressure 
    Simpson, Lydia L.; Meah, Victoria L.; Steele, Andrew R.; Gasho, Christopher; Howe, Connor A.; Dawkins, Tony G.; Busch, Stephen A.; Oliver, Samuel J.; Moralez, Gilberto; Lawley, Justin S.; Tymko, Michael M.; Vizcardo-Galindo, Gustavo A.; Figueroa-Mujíca, Rómulo J.; Villafuerte, Francisco C.; Ainslie, Phillip N.; Stembridge, Mike; Steinback, Craig D.; Moore, Jonathan P. (Wiley, 2020)
    NEW FINDINGS: What is the central question of this study? Does chronic mountain sickness (CMS) alter sympathetic neural control and arterial baroreflex regulation of blood pressure in Andean (Quechua) highlanders? What ...
  • Global Reach 2018: Dysfunctional Extracellular Microvesicles in Andean Highlander Males with Excessive Erythrocytosis 
    Brewster, L. Madden; Bain, Anthony R.; Pacheco Garcia, Vinicius; Fandl, Hannah K.; Stone, Rachel; DeSouza, Noah M.; Greiner, Jared J.; Tymko, Michael M.; Vizcardo-Galindo, Gustavo A.; Figueroa-Mujica, Romulo J.; Villafuerte, Francisco C.; Ainslie, Philip N.; DeSouza, Christopher A. (American Physiological Society, 2021)
    High altitude-related excessive erythrocytosis (EE) is associated with increased cardiovascular risk. The experimental aim of this study was to determine the effects of microvesicles isolated from Andean highlanders with ...
  • Global REACH 2018: High Blood Viscosity and Hemoglobin Concentration Contribute to Reduced Flow-Mediated Dilation in High-Altitude Excessive Erythrocytosis 
    Tremblay, Joshua C.; Hoiland, Ryan L.; Howe, Connor A.; Coombs, Geoff B.; Vizcardo-Galindo, Gustavo A.; Figueroa-Mujica, Romulo J.; Bermudez, Daniela; Gibbons, Travis D.; Stacey, Benjamin S.; Bailey, Damian M.; Tymko, Michael M.; MacLeod, David B.; Gasho, Chris; Villafuerte, Francisco C.; Pyke, Kyra E.; Ainslie, Philip N. (Wolters Kluwer Health, 2019)
    Excessive erythrocytosis (EE; hemoglobin concentration [Hb] >/=21 g/dL in adult males) is associated with increased cardiovascular risk in highlander Andeans. We sought to quantify shear stress and assess endothelial ...
  • Global Reach 2018: reduced flow-mediated dilation stimulated by sustained increases in shear stress in high-altitude excessive erythrocytosis. 
    Tremblay, Joshua C.; Coombs, Geoff B.; Howe, Connor A.; Vizcardo-Galindo, Gustavo A.; Figueroa-Mujica, Romulo J.; Bermudez, Daniela; Tymko, Michael M.; Villafuerte, Francisco C.; Ainslie, Philip N.; Pyke, Kyra E. (American Physiological Society, 2019)
    Excessive erythrocytosis [EE; hemoglobin concentration (Hb) >/= 21 g/dL in adult men] is a maladaptive high-altitude pathology associated with increased cardiovascular risk and reduced reactive hyperemia flow-mediated ...
  • Global REACH 2018: Volume regulation in high-altitude Andeans with and without chronic mountain sickness 
    Steele, Andrew R.; Tymko, Michael M.; Meah, Victoria L.; Simpson, Lydia L.; Gasho, Christopher; Dawkins, Tony G.; Williams, Alexandra Mackenzie; Villafuerte, Francisco C.; Vizcardo-Galindo, Gustavo A.; Figueroa-Mujíca, Rómulo J.; Ainslie, Philip N.; Stembridge, Mike; Moore, Jonathan P.; Steinback, Craig D. (American Physiological Society, 2021)
    The high-altitude maladaptation syndrome known as chronic mountain sickness (CMS) is characterized by polycythemia and is associated with proteinuria despite unaltered glomerular filtration rate. However, it remains unclear ...
  • Global Research Expedition on Altitude-related Chronic Health 2018 Iron Infusion at High Altitude Reduces Hypoxic Pulmonary Vasoconstriction Equally in Both Lowlanders and Healthy Andean Highlanders. 
    Patrician, Alexander; Dawkins, Tony; Coombs, Geoff B.; Stacey, Benjamin; Gasho, Christopher; Gibbons, Travis; Howe, Connor A.; Tremblay, Joshua C.; Stone, Rachel; Tymko, Kaitlyn; Tymko, Courtney; Akins, John D.; Hoiland, Ryan L.; Vizcardo-Galindo, Gustavo A.; Figueroa-Mujíca, Rómulo; Villafuerte, Francisco C.; Bailey, Damian M.; Stembridge, Michael; Anholm, James D.; Tymko, Michael M.; Ainslie, Philip N. (Elsevier, 2021)
    BACKGROUND: Increasing iron bioavailability attenuates hypoxic pulmonary vasoconstriction in both lowlanders and Sherpas at high altitude. In contrast, the pulmonary vasculature of Andeans with chronic mountain sickness ...
