Dislocation after total hip arthroplasty (THA) is a common reason for revision. The last decade fostered a significant increase in the use of dual-mobility cups (DMCs). Here we report our study on the short-term survival rate of a cemented DMC reported to the Swedish Hip Arthroplasty Register (SHAR) compared with other cemented designs used in first-time(More)
PURPOSE To evaluate the effect of lipofection, particle size, and surface coating on labeling efficiency of mammalian cells with superparamagnetic iron oxides (SPIOs). MATERIALS AND METHODS Institutional Review Board approval was not required. Different human cell lines (lung and breast cancer, fibrosarcoma, leukocytes) were tagged by using(More)
INTRODUCTION The aim of this study was to test the mechanical stability of LOQTEQ® HTO plate in comparison to the TomoFix™ internal plate fixator. MATERIALS AND METHODS An unstable fracture gap model with two standardized polyoxymethylene (POM) cylinders was used for this study. With this model 5 LOQTEQ® HTO plates and 5 TomoFix™ were cyclically loaded.(More)
PURPOSE To evaluate the signal characteristics of different iliac artery stents in MR angiography (MRA) at 3 T in comparison with 1.5 T. MATERIALS AND METHODS Sixteen iliac artery stents were implanted in plastic tubes filled with a solution of Gd-DTPA and imaged at 3 T and 1.5 T using a T1-weighted 3D spoiled gradient-echo sequence. Image analysis(More)
UNLABELLED Near-infrared imaging such as fluorescence reflectance imaging (FRI) and fluorescence-mediated tomography (FMT) yields high signal-to-noise ratios (SNRs) and should thus be well suited for cell-tracking studies. Extravasation of monocytes or macrophages (Ms) is one of the earliest events in inflammation. The purpose of this study was to assess(More)
Masticatory efficiency, the subjective experience of masticatory performance, and dietary intake were measured for 43 subjects who were provided with new complete dentures. The subjects were tested on three occasions: with the old complete dentures, with the new complete dentures when free from symptoms, and with the new dentures about 4 months after(More)
A commercially available extract of the aerial parts of Hypericum perforatum, LI 160, showed pronounced activity in selected animal bioassays. These include the forced swimming test (FST) and the tail suspension test, used to determine antidepressant activity, and tests indicating activity on the central nervous system, such as body temperature and ketamine(More)
PURPOSE To prospectively investigate steady-state blood volume measurements for early quantitative monitoring of antiangiogenic treatment with ultrasmall superparamagnetic iron oxide (USPIO)-enhanced magnetic resonance (MR) imaging. MATERIALS AND METHODS The institutional animal care committee approved all experiments. HT-1080 fibrosarcoma-bearing nude(More)
PURPOSE Prospective evaluation of diagnostic accuracy of single field-of-view contrast-enhanced MR Angiography (ceMRA) with 1.0M gadobutrol compared to intraarterial DSA in body arteries. MATERIALS AND METHODS In an European multicenter study 179 patients underwent ceMRA and DSA. For each indication five prospectively defined vessel segments were(More)
PURPOSE To compare a spiral gradient-echo sequence with a radial steady-state free precession sequence and to compare these two interactive real-time cardiac magnetic resonance (MR) imaging examinations with harmonic two-dimensional echocardiography (ECHO) for the evaluation of regional myocardial function. MATERIALS AND METHODS Electrocardiographically(More)
