Abstract Objective. To evaluate the diagnostic utility of single-operator peroral cholangioscopy (SOC) in patients with sclerosing cholangitis. Methods. All patients with sclerosing cholangitis who underwent SOC procedures due to suspicious biliary strictures, in one Swedish and four UK tertiary centers in 2008-2012, were retrospectively enrolled. For each SOC procedure in sclerosing cholangitis,

NA44 uses a 512 channel Si pad array covering 1.5 < eta < 3.3 to study charged hadron production in 158 A GeV Pb+Pb collisions at the CERN SPS. We apply a multiresolution analysis, based on a Discrete Wavelet Transformation, to probe the texture of particle distributions event-by-event, by simultaneous localization of features in space and scale. Scanning a broad range of multiplicities, we look f

Popular Abstract in Swedish Helicobacter pylori är en av de vanligaste infektionerna hos människan. H. pylori framodlades för första gången 1983 av Robin Warren och Barry Marshall. Bakterien ger en kronisk inflammation i magslemhinnan. H. pylori orsakar magsår och möjligheten att behandla sjukdomen med antibiotika har inneburit en revolution inom sjukvården. Hos flertalet sker infektionen i barndoHelicobacter pylori is one of the most common infections in man. The infection is often acquired during childhood and usually results in a chronic life-long inflammation in the gastric mucosa. The aim of our studies was to investigate the association between H. pylori seropositivity and the development of gastric and oesophageal carcinomas. Nested case-control studies were performed in the Malmö P

The transition rates of the intercombination lines 2s2p(3 5)S(2)(0)-->2s(2)2p(2 3)P(1,2) are computed using a systematic configuration interaction method (SCIV3). The calculated lifetime of the upper S-5(2)o, level is in excellent agreement with a recent experiment. The branching ratio of the two lines is very different from earlier, less accurate theoretical values.

An overview of the field of Chiral Lagrangians is given. This includes Chiral Perturbation Theory and resummations to extend, it to higher energies, applications to the muon anomalous magnetic moment, epsilon(1)/epsilon and others.

We present new results on a study of the weak s-process elemental abundances in the M supergiant alpha Ori (M2Iab). We have conducted the abundance analysis through comparison of synthetic with observed spectra in the two infrared spectral regions 0.7 - 1.1 mu m and 2.1 - 2.3 mu m, where the molecular and atomic line densities are less than in the optical region and where many of the relevant elem

This paper concerns a numerical investigation of the heat and fluid flow in V-shaped ribbed ducts. The Navier-Stokes equations and the energy equation are solved in conjunction with a low Reynolds number k-epsilon turbulence model. The Reynolds turbulent stresses are computed with an explicit algebraic stress model (EASM) while the turbulent heat fluxes are calculated with a simple eddy diffusivit
