    • Concentrated Ambient Particles Alter Myocardial Blood Flow During Acute Ischemia in Conscious Canines 

      Bartoli, Carlo R.; Wellenius, Gregory A.; Coull, Brent Andrew; Akiyama, Ichiro; Diaz, Edgar; Lawrence, Joy E.; Okabe, Kazunori; Verrier, Richard Leonard; Godleski, John Joseph (National Institute of Environmental Health Sciences, 2008)
      Background: Experimental and observational studies have demonstrated that short-term exposure to ambient particulate matter (PM) exacerbates myocardial ischemia. Objectives: We conducted this study to investigate the effects ...

    • Mechanisms of Inhaled Fine Particulate Air Pollution–induced Arterial Blood Pressure Changes 

      Bartoli, Carlo R.; Wellenius, Gregory A.; Diaz, Edgar; Lawrence, Joy E.; Coull, Brent Andrew; Akiyama, Ichiro; Lee, Lani M.; Okabe, Kazunori; Verrier, Richard Leonard; Godleski, John Joseph (National Institute of Environmental Health Sciences, 2008)
      Background: Epidemiologic studies suggest a positive association between fine particulate matter and arterial blood pressure, but the results have been inconsistent. Objectives: We investigated the effect of ambient particles ...

    • Rapid Increases in the Steady-state Concentration of Reactive Oxygen Species in the Lungs and Heart After Particulate Air Pollution Inhalation. 

      Gurgueira, Sonia A; Lawrence, Joy E.; Coull, Brent Andrew; Murthy, G G Krishna; González-Flecha, Beatriz (The National Institute of Environmental Health Sciences, 2002)
      In vitro studies suggest that reactive oxygen species contribute to the cardiopulmonary toxicity of particulate air pollution. To evaluate the ability of particulate air pollution to promote oxidative stress and tissue ...
