Age-dependent downregulation of murine cerebral cortical hemoxygenase-1 gene expression is not due to methylation of a 283 bp CpG island region in the promoter as determined by methylation sensitive polymerase chain reaction.

IL6 induced pulmonary branching by involving the p38-MAPK intracellular signaling pathway in the rat fetus. This may be a mechanism by which chorioamnionitis promotes fetal lung maturation.

High mortality in congenital diaphragmatic hernia is principally due to persistent pulmonary hypertension that is resistant to conventional therapy. Using Pinacidil, a KATP channel opener, and glibenclamide (GLI) a KATP blocker, in-vivo and in-vitro demonstrated that activation of KATP channels reduces the pulmonary vascular tone in fetal lambs with CDH supporting development of other therapeutic targets.

Developmental dysplasia of the hip may precipitate hip osteoarthritis. This investigation supports a role for increased birth weight in altering the course of hip development pre-empting measurable degenerative changes in adulthood.

Gastroschisis was associated with a sub-chronic inflammatory process involving macrophages that secrete ferritin, neopterin and calprotectin, as noted in the amniotic fluid and the fibrous peel covering the bowel.

Ultrasound examination of enuretic children that detected bilateral immature ureteric jet waveforms and markedly thickened bladder wall demonstrated multiple significant urodynamic abnormalities perhaps related to vesico-ureteric junction and detrusor muscle immaturity.
