Oesophageal dysmotility, delayed gastric emptying and gastrointestinal symptoms in patients with diabetes mellitus.

Aims Gastroparesis is a common gastrointestinal complication in diabetes mellitus, whereas dysfunction in the other gastrointestinal organs has been less thoroughly investigated. Furthermore, it is not known whether there is any relationship between motility and dysmotility between these organs. The aim of this study was to examine whether diabetic patients with gastrointestinal symptoms also have

Multiparticle-hole States of High Spin in N

High spin states in the nucleus Tc-89 have been studied via the fusion evaporation reaction Ni-58(Ca-40,2 alpha p)Tc-89 at 180 MeV beam energy. The NORDBALL gamma-ray spectrometer equipped with auxiliary detectors for light particle selection was used to measure gamma gamma- and particle-gamma gamma coincidences. Some 60 transitions were placed into a level scheme comprising 38 levels reaching up

Design and Synthesis of New Models for Diiron Biosites

In order to mimic dinuclear active sites of some non-heme diiron proteins, ten new polydentate and potentially dinucleating ligands have been synthesized. Each ligand contains a carboxylate moiety designed to bridge two metal atoms. These central carboxylate moieties are derived from substituted benzoic acids that in turn are linked to terminal nitrogen or oxygen donors by spacers so that framewor

Formation of a region: Source strategies and media images of the Sweden-Danish Oresund Region

The research applies media discourse analysis and late modernity theory to the social construction of the transnational Oresund Region between the South of Sweden and East of Denmark. Based on interviews with PR sources and journalists, analysis of newspaper texts and opinion polls, the study found that despite trans-national aims the region is mainly constructed through Swedish or Danish national

The effect of defects at the steel - concrete interface, exposure regime and cement type on pitting corrosion in concrete

Abstract The effects of defects at the steel-concrete interface, the exposure regime, and the cement type, on the initiation of pitting corrosion in specially designed concrete corrosion cells were investigated. Concrete/mortar corrosion cells with cast-in mild steel electrodes representing the reinforcement were exposed for wetting-drying cycles or submerged in NaCl solution. ParalIei field expos

Structure-function analysis of HAMLET (human alpha-lactalbumin made lethal to tumor cells)

The human genome sequence encodes fewer proteins than expected, suggesting that one protein can have several functions and adjust their structure to meet different structural demands. Changes in tertiary structure have mostly been associated with disease and the most striking example is the prion protein, which changes from a mixed alpha-helical and beta-sheet conformation to the beta-sheet rich,

The HCCI Engine – High Load Performance and Control Aspects

Popular Abstract in Swedish Förbränningsmotorer används på flera platser i samhället där energi behöver göras tillgänglig i form av mekaniskt arbete eller elektrisk energi. Den kanske mest kända tillämpningen är som kraftkälla i en personbil. Förbränningsmotorerna har givetvis ett antal fördelar som bidragit till deras popularitet och omfattande användning - lågt pris, kompakthet, driftsäkerhet ocCurrent combustion engines provide excellent performance for vehicle propulsion and power generation. However, recent demands from society ask for higher efficiencies and lower emissions. These requirements are hard to meet with current technology and call for new solutions. Homogeneous Charge Compression Ignition, HCCI, offers a potential to combine high efficiency with very low emissions. It op

A polar system of intercontinental bird migration

Studies of birdmigration in the Beringia region of Alaska and eastern Siberia are of special interest for revealing the importance of bird migration between Eurasia and North America, for evaluating orientation principles used by the birds at polar latitudes and for understanding the evolutionary implications of intercontinental migratory connectivity among birds as well as their parasites. We use

On dissolution driven crack growth

The formation and growth of a crack in a body subjected to stress driven material dissolution is studied. The rate of material dissolution is proportional to strain energy and curvature of the body surface. The formation of a crack from a plane surface is preceded by an evolving surface roughness. The continued dissolution enhances roughness amplitude resulting in pit formation. As the pit grows d

Bodily mimesisas “the missing link” in human cognitive evolution

It is fairly uncontroversial that there is a large gap between the communicative and cognitive systems of non-human animals and those of human beings. There is much less consensus, however, on what the nature of this gap is, and even less on how it was bridged in evolution.

Binding of immune complexes to erythrocyte CR1 (CD35): difference in requirement of classical pathway components and indication of alternative pathway-mediated binding in C2-deficiency

Deficiency of complement components within the classical pathway is associated with increased risk for immune complex disease. However, C2-deficient individuals often have a mild disease and about 50% are healthy. To study the importance of the different components for immune complex clearance, bovine serum albumin (BSA)/anti-BSA complexes were opsonized in human serum and the binding to erythrocy

Histamine in rheumatoid arthritis

Rheumatoid arthritis (RA) is an autoimmune disease characterized by a persistent inflammation of the synovium, leading to the erosion of articular cartilage and bone. Synovial mast cells and their effector molecule, histamine, receive increased attention as mediators of joint inflammation. The aim of our study was to analyse levels of free histamine in serum and joint fluid of RA patients and to e

Indentation testing of a bone defect filled with two different injectable bone substitutes

Injectable bone substitutes (IBS) based on calcium phosphate (CaP) and/or calcium sulphate (CaS) are used as fillers in bone defects to stimulate bone integration and allow mechanical loading. Two types of IBS, IBS-1 is CaP+20%CaS and IBS-2 is CaS+40% hydroxyapatite, were investigated. The materials were injected into holes in the femur and tibia in rabbits. After 10 weeks the femora were subjecte

Interactions between dendritic cells and epithelial cells in allergic disease

Dendritic cells (DCs) play a crucial role in the sensitisation process. Upon encounter with an allergen, DCs require interactions with other cells and factors for triggering a primary or secondary immune response. Epithelial cells (ECs) express features of accessory cells, Such as expression of HLA-DR, co-stimulatory molecules, functional Fc gamma R, molecules of the antigen-processing machinery,

Singularity formation in the generalized Benjamin-Ono equation

A Fourier-collocation scheme is used to approximate solutions to the generalized Benjamin-Ono equation u(t) + uP(Ux) - Hu(xx) = 0. The numerical simulation suggests that the equation features smooth solutions that become unbounded in finite time.
