Q: Question: Does postnatal growth restriction augment oxygen-induced pulmonary hypertension in a neonatal rat model of bronchopulmonary dysplasia?
Answer: PNGR induces right ventricular and pulmonary vascular remodeling and augments the effects of oxygen in neonatal rats. This may be a powerful tool to investigate the mechanisms that induce PH in low-birth-weight preterm infants with BPD.
A:
yes
