The Swedish Knee Arthroplasty Registry (SKAR) has recorded knee arthroplasties prospectively in Sweden since 1975. The only outcome measure available to date has been revision status. While questionnaires on health outcome may function as more comprehensive endpoints, it is unclear which are the most appropriate. We tested various outcome questionnaires in order to determine which is the best for

First-principles phase diagrams of bismuth-stabilized GaAs- and InP(100) surfaces demonstrate for the first time the presence of anomalous (2 x 1) reconstructions, which disobey the common electron counting principle. Combining these theoretical results with our scanning-tunneling-microscopy and photoemission measurements, we identify novel (2 x 1) surface structures, which are composed of symmetr

Background and Aims: In a retrospective study using stereotactic body radiotherapy (SBRT) in medically inoperable patients with stage I NSCLC we previously reported a local control rate of 88% utilizing a median dose of 15 Gy x 3. This report records the toxicity encountered in a prospective phase II trial, and its relation to coexisting chronic obstructive pulmonary disease (COPD) and cardiovascu

Magnesium chelatase is the first unique enzyme of the chlorophyll biosynthetic pathway. It is composed of three gene products of which the largest is 150 kD. This protein was recently identified as an abscisic acid receptor in Arabidopsis (Arabidopsis thaliana). We have evaluated whether the barley (Hordeum vulgare) magnesium chelatase large subunit, XanF, could be a receptor for the phytohormone.

Purpose: To compare the ability of Fast Swedish interactive threshold algorithm (SITA) short-wavelength automated perimetry (SWAP), lengthier full-threshold SWAP, and standard automated perimetry (SAP) using the SITA Fast program to detect early glaucomatous visual field loss. Design: Cross-sectional prospective study of perimetric diagnostic sensitivity as defined by reference limits determined i

Background Female circumcision (FC) has remained a common practice in the countries where it has traditionally been performed. Following increased global mobility, it has also become a common medical issue in the predominantly non-Islamic countries where an increasing number of immigrants from regions where FC is still traditional, have settled. Objectives To investigate types of FC found in a gro

Eighteen Dunkin-Hartley guinea pigs and 50 NMRI mice were inoculated with Helicobacter pylori and the infection followed by culture, histopathology, antibody response, and plasma levels of the acute-phase proteins albumin, C3, and transferrin for up to 7 weeks. The immune response to H. pylori surface proteins was studied by an enzyme immunoassay (EIA) and Western immunoblot and the plasma levels

The degree of arthritis of the cervical spine was retrospectively studied in cervical spine radiographs from 400 patients with rheumatoid arthritis. In the same cervical radiographs the arthritic destruction of the temporomandibular joints was measured as diminished ramal height from the mandibular angle to the palato-occipital line. Reduced ramal height was found in 76 patients, 69 women and 7 me

This paper develops a statistical model for daily gross primary production (GPP) in boreal and temperate coniferous forests. The model applies the light use efficiency (LUE) approach, which estimates the conversion efficiency of daily absorbed photosynthetically active radiation (APAR) into daily GPP as a product of potential LUE and modifying factors. The latter were derived from daily total APAR

A mobile lidar (light detection and ranging) system for environmental monitoring is described. The optical and electronic systems are housed in a truck with a retractable rooftop transmission and receiving mirror, connected to a 40-cm-diameter vertically looking telescope. Two injection-seeded Nd:YAG lasers are employed in connection with an optical parametric oscillator-optical parametric amplifi

Ballistic imaging is the name applied to a category of optical techniques that were originally developed for medical applications. Recently, ballistic imaging was adapted to acquire instantaneous images of the liquid core inside atomizing sprays; a region that has been heretofore inaccessible to spray researchers. An important difference between spray research and the medical imaging problem is th

This article argues that the official landscape heritage in Sweden is formed in an interplay between regional and national discourses, and that the national ideology during the last century has promoted the preservation of stereotyped landscapes that partly ignores the conditions under which these landscapes were actually formed. A conclusion is that Skåne's landscape heritage runs the risk of bei

Ventilation/perfusion scintigraphy, a first hand method for diagnosis of pulmonary embolism, PE, is challenged by tomography of the pulmonary arteries, CT. An additional method is based upon dead space analysis. Tomographic ventilation/perfusion scintigraphy, V/PSPECT is superior to planar technique. Important is interpretation criteria based upon pattern recognition and clinical information. With

The Manchester Short Assessment of Quality of Life (MANSA) is a short interview, which has received a recent interest in research investigating quality of life in people with mental illness. In the present study, the Swedish version of MANSA is examined with regard to reliability, in terms of internal consistency and construct validity. Ninety-two persons with severe mental illness were interviewe

Flash-induced chlorophyll fluorescence kinetics from photosystem II in thylakoids from the dark-grown wild type and two site-directed mutants of the D1 protein His190 residue (D1-H190) in Chlamydomonas reinhardtii have been characterized. Induction of the chlorophyll fluorescence on the first flash, reflecting electron transport from YZ to P680+, exhibited a strong pH dependence with a pK of 7.6 i

schaemia/reperfusion (I/R) of the colon is an inflammatory condition that leads to tissue injury where reactive oxygen species play a central role. Rose hip is rich in biologically active polyphenols with antioxidative properties, which may be important in prevention of lipid peroxidation. L. plantarum DSM 9843 possesses enzymatic activity towards polyphenols. The objective of this study was to de

Chlorosis in crops grown on calcareous soil is mainly due to iron (Fe) deficiency and can be alleviated by leaf application of soluble Fe2+ or diluted acids. Whether chlorosis in indigenous plants forced to grow on a calcareous soil is also caused by Fe deficiency has, however, not been demonstrated. Veronica officinalis, a widespread calcifuge plant in Central and Northern Europe, was cultivated

We illustrate the scope of time-dependent density-functional theory for strongly correlated (lattice) models out of equilibrium. Using the exact many-body time evolution, we reverse engineer the exact exchange correlation (xc) potential v_(xc) for small Hubbard chains exposed to time-dependent fields. We introduce an adiabatic local density approximation to v_(xc) for the 1D Hubbard model and comp
