Huang et al. investigated the role of Tolllike receptor 2 in a pneumococcal otitis media mouse model. See the article on p. 891.

De Vis et al. describe newly available noninvasive methods for investigating brain hemodynamics in newborns and discuss results obtained using these techniques. See the article on p. 641.

Aranda et al. studied the combined effects of caffeine and ketorolac on oxygen-induced retinopathy in rats. See the article on page 554. Cover design by Erin Dewalt.

Kim and colleagues investigated whether attenuation of hyperoxic lung injury with intratracheal transplantation of human umbilical cord blood–derived mesenchymal stem cells could mitigate brain damage in neonatal rats. See the article on page 415. Cover design by Erin Dewalt.

Schüller et al. investigated the immunostimulatory action of the novel Toll-like receptor–specific agonists R-848 and CpG-B on neonatal antigen-presenting cells. See the article on page 311. Cover design by Erin Dewalt.

Merhar et al. hypothesized that infants with perinatal brain injury would have lower brain activation during a visual functional MRI task and reduced connectivity as compared with healthy controls. See the article on page 43. Cover design by Erin Dewalt.
