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)
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)
We studied epidemiologic and immunologic factors in infants with bronchiolitis caused by influenza virus. The proportion of these infants who were male and who had an immediate family member with a history of asthma was similar to that of a control group of infants with respiratory syncytial virus (RSV) bronchiolitis. In subjects with influenza virus(More)
OBJECTIVE To summarize the risk of occult serious bacterial infection in the youngest febrile infants presenting with either clinical bronchiolitis or respiratory syncytial virus infection. DATA SOURCES We performed a systematic search of the Medline database for studies reporting rates of serious bacterial infection in infants younger than 90 days with(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)
