We tested the hypothesis that targeted transgenic overexpression of human extracellular superoxide dismutase (EC-SOD) would preserve alveolar development in hyperoxia-exposed newborn mice. We exposed newborn transgenic and wild-type mice to 95% oxygen (O2) or air x 7 days and measured bronchoalveolar lavage cell counts, and lung homogenate EC-SOD, oxidized(More)
BACKGROUND Low socioeconomic status is consistently associated with reduced physical and mental health, but the mechanisms remain unclear. Increased levels of urban air pollutants interacting with parental stress have been proposed to explain health disparities in respiratory disease, but the impact of such interactions on mental health is unknown.

Hyperoxia-induced neutrophil infux in neonatal rats may contribute to impaired lung development through oxidative DNA damage. To determine whether blocking neutrophil influx prevents DNA damage, we treated newborn rats with 95% O2 beginning at birth, and at 3 and 4 d with nonimmune immunoglobulin G (IgG) (control) or anti-cytokine-induced neutrophil(More)
