Migration of the acetabular component after revision with impacted morselized allografts: a radiostereometric 2-year follow-up analysis of 21 cases

In a consecutive series of hip revisions due to mechanical loosening, using impacted morselized allografts and cement, we followed 21 acetabular components by radiostereometric analysis (RSA) during 2 years. All but 1 acetabular component migrated in the proximal direction (median 2.1 (0.5-6.4) mm). 6 components migrated in the medial direction (median 0.8 (0.4-1.2) mm) and 6 in the lateral (media

Interfacial dynamics and structure of surfactant layers

The present article provides current opinion on studies of the interfacial dynamics, adsorption, and structure of surfactant layers. The physical principles and applications of physicochemical methods such as tensiometry, ellipsometry, photon correlation spectroscopy, and neutron reflectivity techniques, as well as relevant theoretical aspects related to the adsorption and desorption kinetics, int

Measuring Personnel through Human Resources Accounting Reports: A Procedure for Management of Learning. The Hospital Sector in Northwest Stockholm

In the beginning of 1990s preparations were underway in Sweden to enact a law aimed at making accounting on personnel in the annual reports compulsory. An official investigation resulted in a special report on how to design and report on it. The expectations and the discussions that followed resulted in considerable voluntary implementation of “personnel economics reports” or “human resources acco

Nyfynd av Heppia lutosa på Öland.

A new find of the rare and red-listed lichen Heppia lutosa was made near Tornrör on the NE part of the Great Alvar during a lichenological excursion to Öland in april 2001. A few weeks later, another find was made on the NW part of the Great Alvar near Lilla Vickleby. Only one other recent find has been made of this species, which in Sweden is only known from the Baltic islands of Öland and Gotlan

Protein Fraction of Barley Spent Grain as a New Simple Medium for Growth and Sporulation of Soil Actinobacteria.

A cheap value-added product, the protein fraction of barley spent grains is proposed as a source of a potential and economical cultivation medium. We showed that medium composed of protein fraction extract allows the isolation of actinobacteria, especially Streptomyces, from soil samples, and enhances the sporulation. It was used for the screening and production of the biologically active substanc

Burnout, empathy and sense of coherence among district nurses before and after systematic clinical supervision.

The relationships between, on the one hand, burnout, empathy and sense of cohoerence (SOC) and, on the other, personality traits were investigated, together with the effects of systematic clinical supervision on these phenomena among Swedish district nurses. The results in the supervisory group (n = 21) were compared with those of a comparison group (n = 12) in a quasi-experimental design. Persona

Sprickbildning i puts på isolering - undersökning av grundläggande mekanismer - del 2

Denna rapport avser redovisning av den undersökning som har gjorts för att identifiera de grundläggande mekanismerna som leder till att putsen spricker. Rapporten är en fortsättning på en tidigare rapport med samma titel av samma författare. Denna rapport redovisar de experimentella parameterstudier som hittills har genomförts inom ett SBUF-projekt. Syftet med parameterstudierna är att skapa en up

The quality of reporting and outcome measures in randomized clinical trials related to upper-extremity disorders.

Purpose Randomized clinical trials can provide strong evidence regarding effective treatment options. The quality of reporting and the type of outcome measures used are important when judging whether results justify change in clinical practice. The aim of this study was to assess the quality of reporting of randomized clinical trials related to treatment of upper-extremity disorders, published in

Frequent finding of the androgen receptor A645D variant in normal population.

Background: The androgen receptor A645D mutation has been described in one patient with ambiguous genitalia and one boy with normal phenotype. Objective: Because of this phenotypic variation, we screened a cohort of men from the general population (n = 293) as well as men with the following disorders of the genital tract for the mutation: men with prostate cancer (n = 89), testicular cancer (n = 8

Integrating DNA data and traditional taxonomy to streamline biodiversity assessment: an example from edaphic beetles in the Klamath ecoregion, California, USA

Conservation and land management decisions may be misguided by inaccurate or misinterpreted knowledge of biodiversity. Non-systematists often lack taxonomic expertise necessary for an accurate assessment of biodiversity. Additionally, there are far too few taxonomists to contribute significantly to the task of identifying species for specimens collected in biodiversity studies. While species level

Non-Hodgkin's lymphoma in systemic lupus erythematosus

Background: Recent evidence supports an association between systemic lupus erythematosus (SLE) and non-Hodgkin's lymphoma (NHL). Objectives: To describe demographic factors, subtypes, and survival of patients with SLE who develop NHL. Methods: A multi-site cohort of 9547 subjects with definite SLE was assembled. Subjects at each centre were linked to regional tumour registries to determine cancer

Lipid metabolism in the pancreatic beta-cell. Implications for insulin secretion.

We have investigated the role of lipid metabolism with regard to beta-cell function and insulin secretion. Lipids are known to play a crucial functional role in the pancreatic beta-cell, where they are essential for adequate hormone release, but may also exert a long-term toxic effect, leading to beta-cell dysfunction. Our studies in mice, where insulin resistance and glucose intolerance was induc

Bose-Einstein correlations in the Lund model

By providing the Lund Model fragmentation process with a quantum-mechanical framework we extend the results of previous work to situations where there are very many identical bosons. We investigate the features of the weight distributions in some detail and in particular exhibit three-particle BE-correlations, the influence on the rho-spectrum and the difference between charged and neutral pion co
