A cDNA clone encoding a human B1 bradykinin receptor was isolated from a human embryonic lung fibroblast cDNA library by expression cloning. The photoprotein aequorin was utilized as an indicator of the ability of the B1 receptor agonist [des-Arg10]kallidin to mediate Ca2+ mobilization in Xenopus laevis oocytes injected with RNA. A clone was isolated with a(More)
Bradykinin (BK) B2 receptors in guinea pig ileum were characterized in both membrane and soluble form. [3H]BK bound to a single class of sites with almost identical affinities in membranes prepared from the longitudinal muscle, circular muscle and mucosal layers of the ileum. The pharmacology of the binding in the distinct layers was indistinguishable. The(More)
We report results of a search for weakly interacting massive particles (WIMPS) with the silicon detectors of the CDMS II experiment. This blind analysis of 140.2 kg day of data taken between July 2007 and September 2008 revealed three WIMP-candidate events with a surface-event background estimate of 0.41(-0.08)(+0.20)(stat)(-0.24)(+0.28)(syst). Other known(More)
SuperCDMS is an experiment designed to directly detect weakly interacting massive particles (WIMPs), a favored candidate for dark matter ubiquitous in the Universe. In this Letter, we present WIMP-search results using a calorimetric technique we call CDMSlite, which relies on voltage-assisted Luke-Neganov amplification of the ionization energy deposited by(More)
Kinin B1 receptors on rabbit aorta smooth muscle cells in culture were investigated. [3H]Des-Arg10-kallidin labeled a single site in cells at early passage with an equilibrium dissociation constant of 258 pM and a maximal binding density of approximately 680 sites/cell. Treatment of the same cells for 18 h with epidermal growth factor increased the binding(More)
Dihydropyrimidinones such as compound 12 exhibited high binding affinity and subtype selectivity for the cloned human alpha(1a) receptor. Systematic modifications of 12 led to identification of highly potent and subtype-selective compounds such as (+)-30 and (+)-103, with high binding affinity (K(i) = 0.2 nM) for alpha(1a) receptor and greater than(More)
We report a first search for weakly interacting massive particles (WIMPs) using the background rejection capabilities of SuperCDMS. An exposure of 577 kg days was analyzed for WIMPs with mass <30  GeV/c(2), with the signal region blinded. Eleven events were observed after unblinding. We set an upper limit on the spin-independent WIMP-nucleon cross section(More)
A total of 449 clinical specimens and 199 culture fluids were tested using the Virogen Herpes Slide Test (Wampole Laboratories, Div. Carter-Wallace, Inc., Cranbury, N.J.), a rapid latex agglutination procedure. The results were compared with those obtained with isolation of herpes simplex virus in cell culture followed by identification using(More)
The CDMS low ionization threshold experiment (CDMSlite) uses cryogenic germanium detectors operated at a relatively high bias voltage to amplify the phonon signal in the search for weakly interacting massive particles (WIMPs). Results are presented from the second CDMSlite run with an exposure of 70 kg day, which reached an energy threshold for electron(More)
