A collaborative research study was conducted in order to improve our understanding of the source-to-receptor pathway for ambient fine particulate matter (aerodynamic diameter < or = 2.5 mu m; PM2.5) and subsequently to investigate the identity and sources of toxic components in PM2.5 responsible for adverse health effects in allergic humans. This research(More)
Epidemiological studies have reported that elevated levels of particulate air pollution in urban communities are associated with increases in attacks of asthma based on evidence from hospital admissions and emergency department visits. Principal pathologic features of chronic airway diseases, like asthma, are airway inflammation and mucous hypersecretion(More)
The health effects of ambient fine particulate matter (PM(2.5)) and its potential impact on vascular endothelial function have not been thoroughly investigated. As endothelial dysfunction plays an important role in the pathogenesis of atherosclerosis and its complications, we examined the effects of concentrated fine ambient particles (CAPs) on the plasma(More)
In an experiment with growing Wistar rats of 100 g live weight the N-values and the 15N-frequency of the nitrogen in feces, urine and the experimental carcasses were determined after feeding 15N-labelled wheat. Proceeding from CZARNETZKI's multicompartment model (1969) for N-metabolism in monogastric animals, the measured data were used to calculate the(More)
At least three cultural circumstances have converged to make environmental health information critical, yet highly inaccessible, to many Americans: 1) the declining literacy levels of almost half the population, 2) the growing cultural diversity of the population, and 3) the complexity of environmental health information and science. This paper presents a(More)
The use of intermittently administered doses of vasopressors to correct hypotension in the emergency department (ED), commonly referred to as bolus-dose pressors, push-dose pressors, Neo-sticks, or phenyl sticks, has been widely advocated outside of the traditional printed medical literature. No outcomes data of this practice exist to demonstrate benefits(More)
