We hypothesized that initiation of ventilation in preterm lambs with high volumes would cause lung injury and decrease the subsequent response to surfactant treatment. Preterm were randomized for 30 min after birth 5 ml/kg (VT5), 10 (VT10), or 20 (VT20) tidal then ventilated approximately achieve arterial PCO2 values 50 Torr 6 h age. VT20 had lower compliances, ventilatory efficiencies, higher recoveries protein, alveolar lavages decreased compliances when tested rabbits than VT5 VT10 lambs....

Chromosomal aneuploidy and specific gene mutations are recognized early hallmarks of many oncogenic processes. However, the net effect these abnormalities has generally not been explored. We focused on transient myeloproliferative disorder (TMD) in Down syndrome, which is characteristically associated with somatic GATA1. To better understand functional interplay between trisomy 21 GATA1 hematopoiesis, we constructed cellular disease models using human induced pluripotent stem cells (iPSCs)...

In newborn screening (NBS), it is important to consider the availability of multiplex assays or other tests that can be integrated into existing systems when attempting implement NBS for new target diseases. Recent developments in innovative testing technology have made possible simultaneously screen severe primary immunodeficiency (PID) and spinal muscular atrophy (SMA) using quantitative real-time polymerase chain reaction (qPCR) assays. We describe our experience optional PID SMA Osaka,...

Mice that are surfactant protein (SP) A deficient [SP-A(-/-)] have no apparent abnormalities in lung function. To understand the contributions of SP-A to surfactant, biophysical properties and functional characteristics from normal [SP-A(+/+)] SP-A(-/-) mice were evaluated. SP-A-deficient had a lower buoyant density, percentage large-aggregate forms, an increased rate conversion small-aggregate forms with surface area cycling, sensitivity inhibition minimum tension by plasma protein, tubular...

Prostaglandin D 2 (PGD) is synthesized by hematopoietic PGD synthase (HPGDS) or lipocalin-type PGDS (L-PGDS), depending on the organ in which it produced, and binds specifically to either DP 1 receptors. We investigated role of pathogenesis hypoxic-ischemic encephalopathy (HIE) neonatal mice at postnatal day 7. In wild-type mice, hypoxia-ischemia increased production brain up 90-fold compared with level sham-operated brains 10 min after cessation hypoxia. Whereas size infarct was not changed...

Chromosome abnormalities induces profound alterations in gene expression, leading to various disease phenotypes. Recent studies on yeast and mammalian cells have demonstrated that aneuploidy exerts detrimental effects organismal growth development, regardless of the karyotype, suggesting aneuploidy-associated stress plays an important role pathogenesis. However, whether how this effect alters cellular homeostasis long-term features human are not fully understood. Here, we aimed investigate...

Human cytomegalovirus (CMV) is a leading congenital infectious agent in developed countries. In the past, incidence of infection has been rather low Japan because high seroprevalence CMV present young women. However, this decreasing recent years, so that Japanese neonates may increase and approach level seen other The method was used for detecting DNA reported by Barbi et al.

Abstract Eukaryotic genomes are organised into complex higher-order structures within the nucleus, and three-dimensional arrangement of chromosomes is functionally important for global gene regulation. The existence supernumerary chromosome 21 in Down syndrome may perturb nuclear architecture at different levels, which normally optimised to maintain physiological balance expression. However, it has not been clearly elucidated whether how aberrant configuration affects activities. To...

Abstract Individuals with Down syndrome (DS) commonly show unique pathological phenotypes throughout their life span. Besides the specific effects of dosage-sensitive genes on chromosome 21, recent studies have demonstrated that gain a exerts an adverse impact cell physiology, regardless karyotype.
