Cardiovascular effects in patrol officers are associated with fine particulate matter from brake wear and engine emissions
(East Carolina University, 2004-12-09)
Background: Exposure to fine particulate matter air pollutants (PM2.5) affects heart rate variability parameters, and levels of serum proteins associated with inflammation, hemostasis and thrombosis. This study investigated ...
Increased Nonconducted P-Wave Arrhythmias after a Single Oil Fly Ash Inhalation Exposure in Hypertensive Rats
(East Carolina University, 2009-05)
Background: Exposure to combustion-derived fine particulate matter (PM) is associated with increased cardiovascular morbidity and mortality especially in individuals with cardiovascular disease, including hypertension. PM ...
Mechanisms controlling the acquisition of a cardiac phenotype by liver stem cells
(East Carolina University, 2007-03-06)
The mechanisms underlying stem cell acquisition of a cardiac
phenotype are unresolved. We studied early events during the
acquisition of a cardiac phenotype by a cloned adult liver stem cell
line (WB F344) in a cardiac ...
Coarse Particulate Matter (PM2.5 - 10) Affects Heart Rate Variability, Blood Lipids, and Circulating Eosinophils in Adults with Asthma
(East Carolina University, 2007-05)
INTRODUCTION: We investigated whether markers of airway and systemic inflammation, as well as heart rate variability (HRV) in asthmatics, change in response to fluctuations in ambient particulate matter (PM) in the coarse ...
Exposure to Concentrated Coarse Air Pollution Particles Causes Mild Cardiopulmonary Effects in Healthy Young Adults
(East Carolina University, 2009-07)
Background: There is ample epidemiologic and toxicologic evidence that exposure to fine particulate matter (PM) air pollution [aerodynamic diameter ≤ 2.5 μm (PM2.5)], which derives primarily from combustion processes, can ...
Ambient PM Exposure Up-regulates the Expression of Costimulatory Receptors on Circulating Monocytes in Diabetic Individuals
(2011-06)
BACKGROUND:
Exposure of humans to air pollutants such as ozone and particulate matter (PM) may result in airway and systemic inflammation and altered immune function. One putative mechanism may be through modification of ...
Peat Bog Wildfire Smoke Exposure in Rural North Carolina Is Associated with Cardiopulmonary Emergency Department Visits Assessed through Syndromic Surveillance
(2011-10)
Background: In June 2008, burning peat deposits produced haze and air pollution far in excess of National Ambient Air Quality Standards, encroaching on rural communities of eastern North Carolina. Although the association ...
Association of cardiac and vascular changes with ambient PMin diabetic individuals
(2010)
Background and Objective
Exposure to fine airborne particles (PM2.5) has been shown to be responsible for cardiovascular and hematological effects, especially in older people with cardiovascular disease. Some epidemiological ...
Fine Particulate air Pollution is Associated with Higher Vulnerability to Atrial Fibrillation—The APACR Study
(2011-04)
The acute effects and the time course of fine particulate pollution (PM2.5) on atrial fibrillation/flutter (AF) predictors, including P-wave duration, PR interval duration, and P-wave complexity, were investigated in a ...
Acute Effects of Fine Particulate Air Pollution on Cardiac Arrhythmia: The APACR Study
(2011-03)
Background: The mechanisms underlying the relationship between particulate matter (PM) air pollution and cardiac disease are not fully understood.
Objectives: We examined the effects and time course of exposure to fine ...
