An important goal in rehabilitation engineering is to develop technology that allows individuals with severe motor impairment to practice arm movement without continuous supervision from a rehabilitation therapist. This paper describes the development of such a system, called Therapy WREX or ("T-WREX"). The system consists of an orthosis that assists in arm(More)
The magnitude 7.3 Landers earthquake of 28 June 1992 triggered a remarkably sudden and widespread increase in earthquake activity across much of the western United States. The triggered earthquakes, which occurred at distances up to 1250 kilometers (17 source dimensions) from the Landers mainshock, were confined to areas of persistent seismicity and(More)
[1] Seismicity of the Yellowstone volcanic field, northwest Wyoming, is characterized by swarms of earthquakes (M C < 3) within the 0.64-Myr-old, 70 km by 40 km Yellowstone caldera and between the caldera and the eastern end of the 44-km-long rupture of the M S 7.5 1959 Hebgen Lake, Montana, earthquake. Over 3000 earthquakes with M C < 5 were recorded(More)
A total of 230 patients with localized prostate cancer underwent radical retropubic prostatectomy at UCLA (pathological stage T1-3 N0, M0). Classification into groups included 115 patients with organ confined disease (group 1), 82 with invasion into or through the capsule (group 2) and 33 with seminal vesicle involvement (group 3). Median followup was 48(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)
In cranial electrotherapy stimulation (CES), micro-current levels of electrical stimulation are passed across the head via electrodes clipped to the ear lobes. After successful clinical use of CES with fibromyalgia patients in our clinic, it was decided to test these results with a double-blind, placebo-controlled study in which 60 randomly assigned(More)
Retroperitoneal hematoma (RPH) following cardiac catheterization is an infrequent (0.15% incidence) but morbid complication. During a 13-month study period, 11 patients with a significant RPH requiring operative intervention were identified. The mean transfusion requirement was 8.7 units, with two deaths as a consequence of their RPH. Adjunctive cardiac(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 Vascular invasion commonly occurs in renal cell carcinoma and intraoperative thrombus embolization is a known complication of tumor thrombectomy. We reviewed our experience with this complication to determine frequency, mortality, common factors and management strategies. MATERIALS AND METHODS We retrospectively reviewed a prospective database of(More)
The 3-D P-wave velocity and P-to 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 (V p) and P-wave to S-wave velocity(More)
