Renewed interest in the neovascularity of atherosclerotic plaques has followed the work of Imparato et al., which confirmed the importance of carotid intraplaque hemorrhage in the production of symptomatic extracranial vascular disease. We have studied the detailed histology of 91 carotid atheromatous plaques with particular regard to hemorrhage and(More)
We present observations of L1014, a dense core in the Cygnus region previously thought to be starless, but data from the Spitzer Space Telescope shows the presence of an embedded source. We propose a model for this source that includes a cold core, heated by the interstellar radiation field, and a low-luminosity internal source. The low luminosity of the(More)
BACKGROUND A retrospective case-control study was conducted to investigate risk factors for endophthalmitis following routine intraocular surgery. METHODS A review was performed of consecutive cases of endophthalmitis from three teaching hospitals in the western Sydney region and matched controls from the same institutions between 1996 and 1998. RESULTS(More)
OBJECTIVES The aim of this study was to examine the suitability of nurse practitioners for assessing and managing urgent clinical problems presenting in primary care. METHODS Patients registered at a suburban group practice presenting with acute medical problems were offered the choice of seeing a GP or a nurse practitioner. The outcomes of 1000(More)
We propose that inward, subsonic flows arise from the local dissipation of turbulent motions in molecular clouds. Such " turbulent cooling flows " may account for recent observations of spatially extended inward motions toward dense cores. These pressure-driven flows may arise from various types of turbulence and dissipation mechanisms. For the example of(More)
We present observations of the star formation region NGC 7129 taken with the Multiband Imaging Photometer for Spitzer (MIPS). A significant population of sources, likely pre-main sequence members of the young stellar cluster, is revealed outside the central photoionization region. Combining with Infrared Array Camera (IRAC) and ground-based near-infrared(More)
We present the first Spitzer Infrared Spectrograph 11 observations of the disks around classical T Tauri stars: spectra in the 5.2-30 µm range of six stars. The spectra are dominated by emission features from amorphous silicate dust, and a continuous component from 5 to 8 µm that in most cases comprises an excess above the photosphere throughout our(More)
