An important signal involved in glucose-stimulated insulin secretion is transduced through the action of a lysosomal acid, glucan 1,4-alpha-glucosidase. We investigated the Ca2+ dependency of this enzyme activity in relation to insulin release. In isolated islets, increased levels of extracellular Ca2+ induced a large increase in acid glucan 1,4-alpha-glucosidase activity accompanied by a similar
IDDM is positively associated with HLA-DQA1*0301-DQB1*0302 (DQ8) and DQA1*0501-DQB1*0201 (DQ2) and negatively associated with DQA1*0102-DQB1*0602 (DQ6). The aim of the present study was to analyze the importance of several polymorphic residues and domains of DQalpha and DQbeta, in addition to residue 52 DQalpha and residue 57 DQbeta, with regard to susceptibility or resistance in new-onset 0- to 1
Phononic and magnetic Raman scattering are studied in La2-x-yNdySrxCuO4 with three doping concentrations: x1/8, y = 0; x1/8, y = 0.4; and x = 0.01, y = 0. We observe strong disorder in the tilt pattern of the CuO6 octahedra in both the orthorhombic and tetragonal phases that persist down to 10 K and are coupled to bond disorder in the cation layers around 1/8 doping independent of Nd concentration
It has been predicted theoretically that for some environments, the capacity of wireless multiple-input multiple-output systems can become very low even for uncorrelated signals; this effect has been termed "keyhole" or "pinhole." In this letter, We present the (to our knowledge) first measurement of this effect. The measurements are done in a controlled indoor environment, with transmitter and re
This paper presents a symbol time offset estimator for coherent orthogonal frequency division multiplexing (OFDM) systems. The estimator exploits both the redundancy in the cyclic prefix and available pilot symbols used for channel estimation. The estimator is robust against frequency offsets and is suitable for use in dispersive channels. We base the estimator on the maximum-likelihood estimator
Review of Bjarne Stoklund (ed.), Kulturens nationalisering. Et etnologisk perspektiv på det nationale, dealing with matters of nationalism.
The refugee families face a complex transition due to the nature of the migration. This exposes them to vulnerability in cohesion and family function. Primary Health Care Nurses (PHCN) and Interpreters in Primary Health Care (PHC) play a vital role in their promotion of health because migrant health care is mainly carried out within PHC. The overall aim of this thesis was to reach a comprehensive
Five intersecting resistivity sections have been measured in glaciofluvial deposits hosting an aquifer of regional importance situated along a heavy traffic highway in Sweden. The winter salt spreading has caused a regular salinity increase through the years. For imaging the transport of saltwater in the aquifer, the sections were measured exactly in the same location before and after winter, and
Background: Passive immunization with orally administered antibodies against specific pathogens has previously been successfully used therapeutically in both animal and human studies. We employed a similar strategy for experimental treatment of mice infected with the gastric pathogen Helicobacter pylori. Methods: An anti-H. pylori bovine colostral hyperimmune immunoglobulin preparation (BIC) was g
The surface of the ocean, and so such quantities as the significant wave height, can be thought of as a random surface in space which develops over time. In this paper, we explore certain types of random fields (in space and time) as models for the significant wave height and fit these models to data obtained from the TOPEX-Poseidon satellite. The data consist of observations along different one-d
We present the first results of a larger study into the stellarabundances and chemical trends in long-lived dwarf stars in the solarneighbourhood that belong to (based on their kinematics) the thin andthick galactic disk, respectively. We confirm that the trends of alpha-elements in the thin and thick disk are distinct (this has previouslybeen shown for Mg by Fuhrmann cite{Fuhrmann}, but e.g. Chen
OBJECTIVE: The aim of the present study was to analyze the long-term outcome of mid-clavicle fractures in adults and to evaluate the clinical importance of displacement and fracture comminution. DESIGN: Two hundred twenty-five mid-clavicular fractures that had been nonsurgically treated at Malmo University Hospital were retrospectively evaluated, both clinically and radiographically, an average of
Clinical techniques for early detection of acute hypotension during conventional hemodialysis treatment are lacking, even though intradialytic hypotension is the most common acute complication. In this article, intradialytic hypotension is identified by means of signal analysis of data recorded at two clinics. The database consists of 30 treatments with concurrently acquired signals: the 12-lead e
