Fibril formation of islet amyloid polypeptide (IAPP) is associated with cell death of the insulin-producing pancreatic beta-cells in patients with Type 2 Diabetes Mellitus. A likely cause for the cytotoxicity of human TAPP is that it destroys the barrier properties of the cell membrane. Here, we show by fluorescence confocal microscopy on lipid vesicles that the process of hIAPP amyloid formation

The hybodont form genus Lissodus is taken under revision and found to comprise a number of lineages. Twelve species, stratigraphically extended from the Scythian, Lower Triassic to the Albian, Lower Cretaceous, are retained in Lissodus s.s. Thirteen other species can be included in Lonchidion, here considered as a justified genus, ranging from the Ladinian in the Middle Triassic to the Maastrichti

Popular Abstract in Swedish En ny mätuppställning har utvecklats och tillämpats på öronproppar (hörselproppar). Mätuppställning gör det möjligt att skatta de akustiska egenskaperna i form av en så kallad tvåport. För objektiva mätningar på hörselskydd använder man normalt sett någon form av artificiellt huvud eller öra, med vars hjälp man mäter insättningsdämpningen. Denna insättningsdämpning beskIn this study an experimental setup for measurements of high impedance objects in ducts, yielding the acoustical Two-Port properties of the object, is applied to earplugs. A frequently used experimental setup for measuring objective acoustical properties of earplugs is that of artificial ears. Great effort is spent on duplicating the human ear. The acoustical properties of the earplug are thought

This article reports a literature review which draws together findings targeting families' needs when a child is long-term ill. The databases PubMed and CINHAL were searched from 1999 to 2003 during February 2004. The search terms were child health care, family caregivers, and needs and combinations of these. The search was limited to articles published in English and the Scandinavian languages. T

Background - Mitral annuloplasty is the most common surgical procedure performed for ischemic mitral regurgitation (MR). Surgical mitral annuloplasty is limited by morbidity, mortality, and MR recurrence. We evaluated the safety and feasibility of a transvenous catheter-delivered implantable device to provide a percutaneous alternative to surgical mitral annuloplasty. Methods and Results - Five pa

Accessibility is an important factor in land-use planning and several methods have been developed to calculate and to predict it. Nevertheless, it is seldom applied in planning situations, maybe because many land-use planners and elected officials lack the knowledge and resources needed to use traffic models. Consequently, accessibility is often used as a concept and a goal in daily planning, but

Coherent anti-Stokes Raman spectroscopy (CARS) is an established technique for gas-phase thermometry in combustion. In this work, rotational CARS in the dual-broadband approach has been investigated for flame thermometry in the product gas of ethylene/air flames in a wide range of equivalence ratios (0.5 < phi < 2.5). The nitrogen lines dominated the rotational CARS spectra in the whole equivalenc

Mass-propagation of the spruce bark beetle, Ips typographus, following windfalls and drought is a serious threat to mature spruce forests. Climate change will affect the population dynamics of I. typographus directly as the swarming activity and development rate are mainly controlled by temperature, and indirectly via changes in availability of brood trees. Today, I. typographus is in general univ

Subchondral hematomas have been found with arthroscopy in one third of patients with dislocated distal radial fractures. The aim of the present, prospective study was to determine whether these hematomas might cause radiographic osteoarthrosis. We studied 41 patients (age 20-57 years, 22 women) with a dislocated distal radial fracture. At the time of fracture, 12 patients had subchondral hematomas

The NA44 experiment has measured single-particle inclusive spectra for charged pions, kaons, and protons as a function of transverse mass near midrapidity in 158A GeV/c Pb+Pb collisions. From the particle mass dependence of the observed m(T) distributions, we are able to deduce a value of about 120 MeV for the temperature at thermal freeze-out. From the observed ratios of the rapidity densities, w

Steam-pretreated willow has been found to be a suitable substrate for ethanol production in Sweden. The production of Trichoderma reesei cellulases on steam-pretreated willow (SPW) of varying cellulose content has been studied. Batch fermentations were performed in shake flasks, and in 4- and 22-l fermenters. SPW was found to be a suitable carbon source for cellulase production. At an initial soli

Using a postal questionnaire the prevalence of hand eczema was determined in a general population of 11 798 individuals aged 20 - 77 years who were randomly drawn from the population records. The response rate was 78.1%. One-year prevalence of hand eczema among women varied between 1.9% and 10.8%, with the highest figure among those aged 30 - 39 years. The corresponding figures for men were 2.3% a

We describe affinity partitioning as a preparative method for membranes and membraneous structures such as organelles, cells, and viruses. Biospecific affinity partitioning is carried out in aqueous polymer two- phase systems, commonly with polyethylene glycol and dextran as phase polymers, in an environment compatible with membrane structures. Ideally, two-phase conditions are chosen to partition

Popular Abstract in Swedish Denna avhandling beskriver olika metoder att förbättra motorstabilitet och minska skadliga avgasutsläpp från naturgasmotorer. Gasflöden inuti cylindern mättes med laserdiagnostik, även cylindertryck och avgassammansättning mättes. Sex olika förbränningsrum utvärderades med ovan angivna metoder. Ett högturbulent (brinner snabbt) förbränningsrum visade sig fungera bäst meThe objective of this thesis was to find ways to improve combustion and reduce emissions from supercharged natural gas engines. In-cylinder flow measurements were made with laser doppler velocimetry, LDV, heat release was calculated from cylinder pressures and emissions were measured at various locations. The original combustion chamber was a low turbulence-generating geometry, resulting in an ove
