Substantial neurologic morbidity occurs in survivors of premature birth. Premature infants are exposed to partial oxygen pressures that are fourfold higher compared to intrauterine conditions, even if no supplemental oxygen is administered. Here we report that short exposures to nonphysiologic oxygen levels can trigger apoptotic neurodegeneration in the(More)
OBJECTIVE To investigate the growth of children from pregnancies with gestational diabetes mellitus (GDM) and its association with antenatal maternal, fetal, and recent anthropometric parameters of mother and father. RESEARCH DESIGN AND METHODS In 324 pregnancies of Caucasian women with GDM, BMI before pregnancy, maternal glycemic values, and measurements(More)
Glutamate antagonists limit the growth of human cancers in vitro. The mechanism of anticancer action of NMDA antagonists is not known, however. In this article, we report that the NMDA antagonist dizocilpine inhibits the extracellular signal-regulated kinase 1/2 pathway, an intracellular signaling cascade that is activated by growth factors and controls the(More)
Fatal congenital nonlysosomal cardiac glycogenosis has been attributed to a subtype of phosphorylase kinase deficiency, but the underlying genes and mutations have not been identified. Analyzing four sporadic, unrelated patients, we found no mutations either in the eight genes encoding phosphorylase kinase subunits or in the two genes encoding the muscle(More)
Pharmacological blockade of NMDA receptor function induces apoptotic neurodegeneration in the developing rat brain. However, the use of NMDA receptor antagonists as anesthetics and sedatives represents a difficult-to-avoid clinical practice in pediatrics. This warrants the search for adjunctive neuroprotective measures that will prevent or ameliorate(More)
Introduction: Hypoxia induces transcription of vascular endothelial growth factor (VEGF) and erythropoietin (EPO) genes. We set up the hypothesis that elevated intracranial pressure in patients with hydrocephalus triggers release of VEGF and EPO into cerebrospinal fluid (CSF). Methods and results: VEGF and EPO concentrations, measured in 57 CSF aliquots(More)
Necrotising enterocolitis (NEC) is the predominant immaturity-associated disease of the bowel in the preterm neonate and leads to substantial mortality and long-term morbidity. Diagnostic features of NEC include, apart from the clinical presentation, laboratory and radiological parameters. Pneumatosis intestinalis (PI) on abdominal radiographs is regarded(More)
Pulmonary surfactant is essential to maintain alveolar patency, and invariably fatal neonatal lung disease has been recognized to involve mutations in the genes encoding surfactant protein-B or ATP-binding cassette transporter family member ABCA3. The lipid transporter ABCA3 targets surfactant phospholipids to lamellar bodies that are lysosomal-derived(More)
IMPORTANCE Treatment of respiratory distress syndrome in premature infants with continuous positive airway pressure (CPAP) preserves surfactant and keeps the lung open but is insufficient in severe surfactant deficiency. Traditional surfactant administration is related to short periods of positive pressure ventilation and implies the risk of lung injury.(More)
Interleukin (IL)-18 is a potent inflammatory cytokine of the IL-1 family. It is synthesized as an inactive precursor (pro-IL-18), which is cleaved into its functionally active form by caspase-1. Resident cells of the CNS express IL-18 and caspase-1 constitutively, thus providing a local IL-18-dependent immune response. Recent studies have highlighted a(More)
