RT-PCR results for eNOS.

<p>There were no same-day differences between control and NEC. n = 4–6 per group. *  =  p<0.05.</p

RT-PCR results for NOX1.

<p>Both control and NEC samples increased from D0 to D1. There were no same-day differences between control and NEC. n = 4–5 per group. *  =  p<0.05.</p

Immunofluorescence for p47^phox and GP91^phox on D1, D2, and D4.

<p>Fig. 8a shows control samples, and Fig. 8b shows NEC samples. The images are of p47^phox (red) GP91^phox (green), and the co-localization of the two proteins (yellow).</p

Effects of inhibitors on NADPH- dependent O₂^•– production on D4 small intestinal homogenates.

<p>n = 6 for control, 5 for NEC. *  =  p<0.05</p

NADPH-dependent O₂^•– production in small intestinal homogenates from D4.

<p>n = 5–7 per group F =  Formula, F/H  =  Formula and hypoxia, F/L  =  Formula and LPS, F/H/L  =  Formula, Hypoxia, and LPS (NEC model). *  =  p<0.05 between NEC and each group.</p

NADPH-dependent O₂^•– production in small intestinal homogenates from D0-4.

<p>Same-condition experimental groups that had significant differences represented by error bars. Both control and NEC samples were significantly different between D0 and D4. In addition, significant differences between control and NEC samples occurred on D0, D3, and D4 (p<0.05). n = 5–6 per group *  =  p<0.05, ** p<0.01.</p
