The Yellowstone caldera began a rapid episode of ground uplift in mid-2004, revealed by Global Positioning System and interferometric synthetic aperture radar measurements, at rates up to 7 centimeters per year, which is over three times faster than previously observed inflation rates. Source modeling of the deformation data suggests an expanding volcanic(More)

During the period from 1975 to 1991, 41 patients with 60 visceral artery aneurysms were treated at the Affiliated Hospitals of Emory University. The total included 13 patients in whom 16 aneurysms were treated primarily by transarterial embolization. There were seven hepatic artery aneurysms, three splenic artery aneurysms, three gastroduodenal artery(More)
A total of 601 patients who underwent radical retropubic prostatectomy for localized prostate cancer at our institution was followed with serial prostatic specific antigen (PSA) determinations. Three separate groups were delineated by pathological stage: 293 patients with organ confined disease, 215 with involvement of the capsule or positive margins and 93(More)
The Yellowstone hotspot commonly is thought to result from a stationary mantle plume rooted in the lower mantle over which North America moves. Yet Yellowstone’s initiation and its association with the “backward” propagating Newberry hotspot across eastern Oregon pose difficult questions to those explaining Yellowstone as a simple consequence of a(More)
[1] The movement of the lithosphere over a stationary mantle magmatic source, often thought to be a mantle plume, explains key features of the 16 Ma Yellowstone–Snake River Plain volcanic system. However, the seismic signature of a Yellowstone plume has remained elusive because of the lack of adequate data. We employ new teleseismic P and S wave traveltime(More)
The 3-D P-wave velocity and Pto S-wave velocity ratio structure of the Yellowstone volcanic field, Wyoming, has been determined from local earthquake tomography using new data from the permanent Yellowstone seismic network. We selected 3374 local earthquakes between 1995 and 2001 to invert for the 3-D P-wave velocity (Vp) and Pwave to S-wave velocity ratio(More)
When normal individuals eat 0.33 g protein N/kg body weight (BW)((3/4)) per day, they excrete 10-15 mg urea N/h per kg BW((3/4)). If they now ingest (at 0 h) 0.27 (dose A), 0.40 (dose B), 0.53 (dose C), 0.94 (dose D), or 1.33 (dose E) g protein N/kg BW((3/4)) (in the form of casein, ovalbumin, or lactalbumin), the rate of urea N excretion accelerates within(More)
PURPOSE We determined the prognostic significance of incidentally discovered renal cell carcinoma in the era of increased incidental detection. MATERIALS AND METHODS We reviewed the records of 633 consecutive patients who underwent radical or partial nephrectomy for renal cell carcinoma at our institution between 1987 and 1998. Patients were divided into(More)
The external sphincter spasticity syndrome is described with regard to diagnosis, etiology, pathophysiology and treatment. Use of urodynamic techniques (especially urethral pressure profile and diagnostic pudendal blocks) and adrenolytic agents and diazepam in the treatment of the dysfunction is discussed. We consider this clinical entity to be much more(More)
