OBJECTIVE To determine the incidence of apnea in infants hospitalized with respiratory syncytial virus (RSV) bronchiolitis and identify relevant risk factors from the available literature. STUDY DESIGN A systematic search of available databases for studies reporting the rate of apnea in a consecutive cohort of infants hospitalized with RSV infection was(More)
[1] Particulate organic carbon (POC) export fluxes were estimated in the shelf-slope region of the Chukchi Sea using measurements of 234 Th À238 U disequilibria and the POC/ 234 Th ratio in large (>53-mm) particles. These export fluxes were used in conjunction with rates of primary productivity and benthic carbon respiration to construct a POC budget for(More)
OBJECTIVE To determine whether the use of hypotonic vs isotonic maintenance fluids confers an increased risk of hyponatremia in hospitalized children. STUDY DESIGN A search of MEDLINE (1946 to January 2013), the Cochrane Central Registry (1991 to December 2012), Cumulative Index for Nursing and Allied Health Literature (1990 to December 2012), and(More)
Actin cables of budding yeast are bundles of F-actin that extend from the bud tip or neck to the mother cell tip, serve as tracks for bidirectional cargo transport, and undergo continuous movement from buds toward mother cells [1]. This movement, retrograde actin cable flow (RACF), is similar to retrograde actin flow in lamellipodia, growth cones,(More)
and Daniel Tzabbar for help with data coding, as well as three anonymous reviewers for in-depth comments on methods and theory. ABSTRACT We examined the effects of educational and nationality diversity on work teams' information use. We theorize that some demographic dimensions, such as nationality, trigger social categorization and limit the value of(More)
The ages of the oldest stars in the Galaxy indicate when star formation began, and provide a minimum age for the Universe. Radioactive dating of meteoritic material and stars relies on comparing the present abundance ratios of radioactive and stable nuclear species to the theoretically predicted ratios of their production. The radioisotope 232Th (half-life(More)
Context. The primordial lithium abundance is a key prediction of models of big bang nucleosynthesis, and its abundance in metal-poor dwarfs (the Spite plateau) is an important, independent observational constraint on such models. Aims. This study aims to determine the level and constancy of the Spite plateau as definitively as possible from homogeneous(More)
We have investigated the poorly-understood origin of nitrogen in the early Galaxy by determining N abundances from the NH band at 336 nm in 35 extremely metal-poor halo giants, with carbon and oxygen abundances from Cayrel et al. (2004), using high-quality ESO VLT/UVES spectra (30 of our 35 stars are in the range −4.1 < [Fe/H] < −2.7 and 22 stars have(More)
PURPOSE We analyzed the relative contribution of detrusor instability and difficult arousal from sleep in the genesis of nocturnal enuresis (NE), and evaluate a clinical feature that may prospectively help differentiate patients with monosymptomatic NE (mono NE) from those with diurnal voiding symptoms (DVSs) of urgency and urge incontinence associated with(More)
