BACKGROUND: Hutchinson-Gilford progeria syndrome (HGPS) is an ultra-rare, fatal, segmental premature aging syndrome caused by the aberrant lamin A protein, progerin. The protein farnesyltransferase inhibitor, lonafarnib, ameliorates some aspects of cardiovascular and bone disease. STUDY DESIGN: We performed a prospective longitudinal survey of plasma proteins in 24 children with HGPS (an estimated 10% of the world's population at the time) at baseline and on lonafarnib therapy, compared to age and gender-matched controls using a multi-analyte, microsphere-based immune-fluorescent assay...

BACKGROUND: Despite decades have passed since its discovery, accurate biomarkers of Respiratory syncytial virus (RSV) disease activity and effective therapeutic strategies are still lacking. The high mobility group box type 1 (HMGB1) protein has been proposed as a possible link between RSV and immune system, but only limited information is currently available to support this hypothesis. METHODS: Expression of HMGB1 gene and protein were analyzed by quantitative PCR, ELISA, Western blot, immunocytochemistry, and confocal microscopy in immortalized and primary human bronchial epithelial cells, as well as in rat pup lungs...

BACKGROUND: Nasal continuous positive airway pressure (NCPAP) and nasal intermittent positive pressure ventilation (NIPPV), forms of non-invasive ventilation (NIV) for respiratory support, are increasingly being chosen as the initial treatment for neonates with surfactant (SF) deficiency. Our objective was to compare NCPAP with NIPPV with or without SF administration as a primary mode of ventilation. METHODS: Twenty-four newborn piglets with SF-deficient lung injury produced by repetitive bronchoalveolar lavages were randomly assigned to NCPAP or NIPPV, with or without SF administration (InSurE method)...

BACKGROUND: The toll-like receptor 4 (TLR4) has been reported to play an important role in necrotizing enterocolitis (NEC). As an established regulator of TLR4, vitamin D has been demonstrated to be intestinal-protective. This study aims at finding out whether the vitamin D/vitamin D receptor (VDR) pathway ameliorates NEC by regulating TLR4. METHODS: Serum 25(OH)D was tested and compared in 15 preterm infants with NEC, 12 preterm infants without known complications and 20 healthy term infants...

BACKGROUND: Extracellular adenine nucleotides contribute to ischemia-reperfusion injury following infant cardiopulmonary bypass (CPB), while conversion to adenosine may be protective. Alkaline phosphatase (AP), a key enzyme responsible for this conversion, decreases after infant CPB. Indirect evidence suggests that soluble CD73 may simultaneously increase and partially offset this loss of AP. We sought to measure CD73 levels in infants undergoing CPB and determine its association with adenosine production capacity and post-operative support requirements...

BACKGROUND: Globally, approximately 10% of infants are born before full-term. Preterm birth exposes the heart to the demands of postnatal cardiovascular function before cardiac development is complete. Our aim was to examine, in hearts collected from infants at autopsy, the effects of preterm birth on myocardial structure and on cardiomyocyte development. METHODS AND RESULTS: Heart tissue was collected at perinatal autopsies of 16 infants who died following preterm birth between 23-36 weeks gestation, and survived for 1-42 days; the hearts of 37 appropriately grown stillborn infants, aged 20-40 weeks gestation, were used for comparison...

BACKGROUND: Untreated Phenylketonuria (PKU), one of the most common human genetic disorders, usually results in mental retardation. While a protein-restricted artificial diet can prevent retardation, dietary compliance in adults is often poor. In pregnant PKU women, noncompliance can result in maternal PKU syndrome, where high phenylalanine (Phe) levels cause severe fetal complications. Enzyme substitution therapy using phenylalanine ammonia lyase (PAL) corrects PKU in BTBR phenylalanine hydroxylase (Pahenu2) mutant mice, suggesting a potential for maternal PKU syndrome treatment in humans...
