Shear wave Dispersion Ultrasound Vibrometry (SDUV), is an acoustic radiation force based technique that measures tissue shear viscoelasticity by characterizing shear wave speed dispersion. One of the potential applications of this technique is the non-invasive measurement of liver viscoelasticity to stage liver fibrosis. In this study, a Philips' iU22 ultrasound system was modified to allow for the...
This paper presents preliminary efforts by agencies managing California’s water resources to incorporate climate change research into their planning and management tools. Projected increases in air temperature may lead to changes in the precipitation patterns, runoff timing and volume, sea level rise, and changes in the amount of irrigation water needed due to modified evapotranspiration rates. Historical...
We tested the hypothesis that a single 24-hour urine sample for stone risk analysis would be sufficient for the simplified medical evaluation of urolithiasis. We retrospectively analyzed stone risk profile data on 24-hour urine samples obtained during random and restricted diets in 225 patients with recurrent urolithiasis. In 2 random samples we noted no significant difference in urinary calcium,...
