The compressive sensing algorithm BPDN applied to RCS ISAR measurements is investigated in this paper. It is used to acquire ISAR images from data sets that are incomplete if conventional back projection is used to process images. The aim of the study is to determine if the algorithm can be used to extract accurate RCS values for parts of the measured objects when there are azimuth angle gaps in t
Three-dimensional (3D) solar maps based on Radiance simulations are presented for a future city district in southern Norway. The surface mapping method provides the commercial developer with a practical tool to evaluate the potential for building integrated photovoltaics (BIPV). The solar maps identify the optimum roof and facade areas available for solar energy utilization. The importance of BIPV
Objectives: To assess whether partial meniscectomy is associated with increased risk of radiographic osteoarthritis (ROA) and worsening cartilage damage in the following year. Methods: We studied 355 knees from the Osteoarthritis Initiative that developed ROA (Kellgren-Lawrence grade ≥ 2), which were matched with control knees. The MR images were assessed using the semi-quantitative MOAKS system.
Purpose: To explore the knowledge necessary for adoption and implementation of the Assessment of Learning Powered mobility use (ALP) tool in different practice settings for both adults and children. To consult with a diverse population of professionals working with adults and children, in different countries and various settings; who were learning about or using the ALP tool, as part of exploring
Purpose We compared clinical characteristics and cancer specific mortality in men diagnosed with prostate cancer before vs after age 50 years. Materials and Methods A total of 919 men 35 to 49 years old and 45,098 men 50 to 66 years old who were diagnosed with prostate cancer between 1998 and 2012 were identified in PCBaSe (Prostate Cancer data Base Sweden). Cancer specific mortality was compared
Purpose: The aim of the study was to explore patients’ long-term experience of a congenital hand problem, and the consequences for daily life. Method: Fifteen participants with a median age 24 years (17–55 years), born with thumb hypoplasia/aplasia or thumb duplication were interviewed using a semi-structured interview guide. The interviews were subjected to qualitative content analysis. Results:
Objectives: Pentraxin 3 (PTX3) is a locally produced multifunctional protein involved in inflammation, matrix deposition, and immunity. As patients with seropositive rheumatoid arthritis (RA) have a more severe disease course and higher risk of joint destruction than seronegative patients, the aim of the present study was to examine differences in PTX3 in synovial fluid (SF) (and serum) in seropos
BACKGROUND Both genetic and lifestyle factors contribute to individual-level risk of coronary artery disease. The extent to which increased genetic risk can be offset by a healthy lifestyle is unknown. METHODS Using a polygenic score of DNA sequence polymorphisms, we quantified genetic risk for coronary artery disease in three prospective cohorts - 7814 participants in the Atherosclerosis Risk in
While addition of managed honeybees (Apis mellifera) improves pollination of many entomophilous crops, it is unknown if it simultaneously suppresses the densities of wild insects through competition. To investigate this, we added 624 honeybee hives to 23 fields of oilseed rape (Brassica napus L.) over 2 years and made sure that the areas around 21 other fields were free from honeybee hives. We dem
High-dose melphalan and autologous stem cell transplantation (HDM/ASCT) is widely used in immunoglobulin light chain (AL) amyloidosis, but the benefit is debated mainly because of the high treatment-related mortality (24% in a randomised study comparing HDM/ASCT with oral melphalan/dexamethasone). We report here on the long-term outcome of all patients treated with HDM/ASCT for AL amyloidosis in S
Objective: To determine the true incidence of complete uterine rupture and uterine dehiscence among women delivered by cesarean section after a previous cesarean section. Methods: Medical records of all women who delivered at University Hospital in Malmö, Sweden, during 2005–2009 (n = 21 420) were retrieved from the electronic patient record system (EPRS). After adjustment for inaccuracies, 716 wo
Objective To determine if exercise therapy is superior to arthroscopic partial meniscectomy for knee function in middle aged patients with degenerative meniscal tears. Design Randomised controlled superiority trial. Setting Orthopaedic departments at two public hospitals and two physiotherapy clinics in Norway. Participants 140 adults, mean age 49.5 years (range 35.7-59.9), with degenerative media
Genome-wide association studies (GWASs) have identified 19 susceptibility loci for Alzheimer’s disease (AD). However, understanding how these genes are involved in the pathophysiology of AD is one of the main challenges of the “post-GWAS” era. At least 123 genes are located within the 19 susceptibility loci; hence, a conventional approach (studying the genes one by one) would not be time- and cost
Ternary III–V nanowires (NWs) cover a wide range of wavelengths in the solar spectrum and would greatly benefit from being synthesized as position-controlled arrays for improved vertical yield, reproducibility, and tunable optical absorption. Here, we report on successful selective-area epitaxy of metal-particle-free vertical InxGa1−xP NW arrays using metal–organic vapor phase epitaxy and detail t
Purpose: The interest in measurements of magnetic resonance imaging relaxation times, T1, T2, T2∗, with intention to characterize healthy and diseased lungs has increased recently. Animal studies play an important role in this context providing models for understanding and linking the measured relaxation time changes to the underlying physiology or disease. The aim of this work was to study how th
Background Regenerex is a novel porous titanium construct with a three-dimensional porous structure and biomechanical characteristics close to that of normal trabecular bone. The aim of this study was to compare this novel construct to a well-proven porous plasma sprayed tibial (PPS) implant after total knee arthroplasty. Methods Sixty-one patients scheduled for an uncemented TKA were randomized t
Context: Adhesion G protein-coupled receptor (GPCR)-G1 (ADGRG1) is the most abundant GPCR in human pancreatic islets, but its role in islet function is unclear. Objective: Investigate how ADGRG1 expression and activation by its ligand, collagen III, impacts β-cell function in normal and type 2 diabetic (T2D) islets. Design: Genes associated with the ADGRG1 in human islets was probed by RNA-sequenc
Objectives Regulations heavily control medical technology (MT), which often includes information technology (IT), but staff experiences related to these regulations are unknown. The study aim was to assess Swedish IT/MT staff experiences regarding regulations for medical devices and medical information systems. Methods An anonymous, ten-item, self-report questionnaire was administered to IT and MT
Background: Osteodex (ODX) is a cytotoxic bone-targeting polybisphosphonate, intended for treatment of bone metastasis from castration-resistant prostate cancer (CRPC). The primary objective of this study was to describe the tolerability and toxicity of such treatment by defining its maximum tolerated dose (MTD) and dose-limiting toxicity (DLT). Patients and Methods: Twenty-eight patients with cas
