Searches for the neutral Higgs bosons h 0 and A 0 are used to obtain limits on the Type II Two Higgs Doublet Model (2HDM(II)) with no CP–violation in the Higgs sector and no additional particles besides the five Higgs bosons. The analysis combines approximately 170 pb −1 of data collected with the OPAL detector at √ s ≈ 189 GeV with previous runs at √ s ≈ m(More)
Putative receptors for endothelin were localised autoradiographically in frozen sections of rat and human brain using [125I]endothelin as a ligand. In the rat brain the highest densities were in the granular layer of the cerebellum, choroid plexus, hippocampus, and habenular nucleus. Similar brain high densities were found in the human cerebellum and(More)
A1 adenosine receptors were labeled in rat brain sections with the antagonist [3H]8-cyclopentyl-1,3-dipropylxanthine ([3H]DPCPX) and visualized at the light microscopic level using autoradiography. The specific binding of [3H]DPCPX to the sections showed the pharmacological characteristics of A1 adenosine receptors and was accompanied by very low levels of(More)
For the first time, patterned growth of boron nitride nanotubes is achieved by catalytic chemical vapor deposition (CCVD) at 1200 °C using MgO, Ni, or Fe as the catalysts, and an Al 2 O 3 diffusion barrier as underlayer. The as-grown BNNTs are clean, vertically aligned, and have high crystallinity. Near band-edge absorption ∼6.0 eV is detected, without(More)
A1-adenosine receptors were identified in sections of rat brain and guinea pig kidney with the radioiodinated agonist 125I-N6-p-hydroxyphenylisopropyladenosine (125I-HPIA) using in vitro autoradiography. The affinities of adenosine receptor ligands in competing with 125I-HPIA binding to tissue sections were in good agreement with those found in membranes,(More)
OBJECTIVE To investigate the excitability of segmental and suprasegmental systems in patients with primary restless legs syndrome (pRLS) by measuring the cortical silent period (C-SP) and the peripheral silent period (P-SP). BACKGROUND There is some evidence that RLS may be the motor manifestation of normal CNS periodicity that becomes disinhibited under(More)
Measurement of ψ(2S) meson production in pp collisions at √ s = 7 TeV Abstract The differential cross-section for the inclusive production of ψ(2S) mesons in pp collisions at √ s = 7 TeV has been measured with the LHCb detector. The data sample corresponds to an integrated luminosity of 36 pb −1. The ψ(2S) mesons are reconstructed in the decay channels(More)
