BACKGROUND/AIMS Disappearance of gallbladder stones after shock-wave lithotripsy combined with bile acid therapy depends on mechanical evacuation and dissolution of fragments. Many patients with gallstones have impaired gallbladder emptying and may show delayed stone clearance after lithotripsy. METHODS The effect of gallbladder emptying on gallstone(More)
The CRESST cryogenic direct dark matter search at Gran Sasso, searching for WIMPs via nuclear recoil, has been upgraded to CRESST-II by several changes and improvements. The upgrade includes a new detector support structure capable of accommodating 33 modules, the associated multichannel readout with 66 SQUID channels, a neutron shield, a calibration source(More)
BACKGROUND Although it has been shown that chronic administration of ursodeoxycholic acid increases gallbladder fasting and residual volume, it is unknown whether ursodeoxycholic acid exerts an acute effect on gallbladder volume. We therefore evaluated the effect of a single oral dose of ursodeoxycholic acid on gallbladder volume in healthy volunteers. (More)
The frequency of individual genetic mutations conferring drug resistance (DR) to Mycobacterium tuberculosis has not been studied previously in Central America, the place of origin of many immigrants to the United States. The current gold standard for detecting multidrug-resistant tuberculosis (MDR-TB) is phenotypic drug susceptibility testing (DST), which(More)
The CRESST experiment monitors 300 g CaWO 4 crystals as targets for particle interactions in an ultra low background environment. In this paper, we analyze the background spectra that are recorded by three detectors over many weeks of data taking. Understanding these spectra is mandatory if one wants to further reduce the background level, and allows us to(More)
Scintillating CaWO 4 single crystals are a promising multi-element target for rare-event searches and are currently used in the direct dark matter experiment CRESST (Cryogenic Rare Event Search with Superconducting Thermometers). The relative light output of different particle interactions in CaWO 4 is quantified by quenching factors (QFs). These are(More)
Intermetallic TiAl alloys with a significant volume fraction of the body-centered cubic β-phase at elevated temperatures have proven to exhibit good processing characteristics during hot-working. Being a strong β stabilizer, Mo has gained importance as an alloying element for so-called β/γ-TiAl alloys. Unfortunately, the effect of Mo on the appearing phases(More)
CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) is an experiment located at the Gran Sasso underground laboratory and aimed at the direct detection of dark matter in the form of WIMPs. The setup has just completed a one year commissioning run in 2007 and is presently starting a physics run with an increased target mass. Scintillating(More)
