Outcomes in symptomatic preterm infants with postnatal cytomegalovirus infection.

Premature infants are at risk for developing symptomatic postnatal cytomegalovirus (CMV) disease, including sepsis-like syndrome. We performed a retrospective case-control study including infants born before 32 weeks of gestation and diagnosed with symptomatic postnatal CMV infection during the neonatal period. Neurodevelopmental outcome was evaluated using the Kyoto Scale of Psychological Development 2001 at 18 months of corrected age and at 3 years of age.

Factors related to home health-care transition in trisomy 13.

Trisomy 13 (T13) is accompanied by severe complications, and it can be challenging to achieve long-term survival without aggressive treatment. However, recently, some patients with T13 have been receiving home care. We conducted this study to investigate factors related to home health-care transition for patients with T13.

Progressive aortic root and pulmonary artery aneurysms in a neonate with Loeys-Dietz syndrome type 1B.

Loeys-Dietz Syndrome (LDS) is an autosomal dominant aortic aneurysm syndrome with multisystem involvement, caused by heterozygous mutations of transforming growth factor beta receptor type 1 (TGFBR1) or type 2 (TGFBR2) genes. We report on a neonate with the disorder caused by a known TGFBR2 mutation, who developed neonatal-onset progressive dilation of the aortic valve and aneurysms of the aortic root and main pulmonary artery (PA) associated with a large left-to-right shunt via a ventricular septal defect (VSD) and an atrial septal defect. He also had skeletal features (flexion contractures of the fingers, talipes equinovarus, a cleft palate, and joint laxity), mild facial dysmorphisms, and developmental delay.

Water at interfaces.

Electrolyte cations and anions in aqueous solutions are hydrogen bond breaker. We found that most of anions are strong hydrogen bond breaker whereas cations are not. Further, the electro-reduction of Mg(H2O)6(2+) to Mg(OH)2 and the growth of the Mg(OH)2 were observed on Au electrode surface at negative electrode potential.

Methanol oxidation on a Pt(111)-OH/O surface.

The methanol oxidation on a hydroxylated Pt (Pt(111)-OH) surface has been investigated by means of infrared reflection absorption spectroscopy (IRAS) in ultra-high vacuum (UHV) and in acidic solution. The Pt(111)-OH surface in UHV was prepared by introducing water molecules on a Pt(111)-(2 x 2)-O surface and annealed at temperature higher than 160 K. Methanol was then, introduced to the Pt(111)-OH surface to show the dependence of the reaction intermediate on the annealing temperature.

A new structure of water layer on Cu(111) electrode surface during hydrogen evolution.

A layered structure of water molecules formed on a Cu(111) electrode surface during hydrogen evolution in sulfuric acid solution was studied by surface X-ray diffraction and infrared reflection absorption methods. Water molecules in the surface layers take a closest pack-like stacking structure with nearest-neighbor oxygen-oxygen distances in intra-(0.322(5) nm) and inter-(0.

Monomer structures of water adsorbed on p(2 x 2)-Ni(111)-O surface at 25 and 140 K studied by surface X-ray diffraction.

The structures of a monomeric water molecule adsorbed on p(2 x 2)-Ni(111)-O surface were determined by difference Fourier calculations. At temperatures of 25 K, water molecules chemisorb predominantly at 2 x 2 oxygen atom sites, forming an OH---O(ad) (2 x 2) hydrogen bond. A 2 x 2 oxygen atom (O(ad)) is surrounded by one to three monomeric water molecules, which take statistically disordered positions with threefold symmetry.
