Cone-beam computed tomography, a new low-dose three-dimensional imaging technique for assessment of bone erosions in rheumatoid arthritis : reliability assessment and comparison with conventional radiography – a BARFOT study

Objectives: To determine the intra- and inter-observer agreement of erosions detected and scored with cone-beam computed tomography (CBCT) of bones in the hands and feet, and to compare CBCT with conventional radiography (CR) for assessment of bone erosions in patients with long-standing rheumatoid arthritis (RA). Method: Thirty patients with long-standing RA from the Better Anti-Rheumatic Pharmac

Low risk for hip fracture and high risk for hip arthroplasty due to osteoarthritis among Swedish farmers

Summary: We aimed to study the risk of hip fracture and risk of hip arthroplasty among farmers in Sweden. Our results indicate that farming, representing an occupation with high physical activity, in men is associated with a lower risk of hip fracture but an increased risk of hip arthroplasty. Introduction: The risks of hip fracture and hip arthroplasty are influenced by factors including socioeco

The contribution of the ARIEL space mission to the study of planetary formation

The study of extrasolar planets and of the Solar System provides complementary pieces of the mosaic represented by the process of planetary formation. Exoplanets are essential to fully grasp the huge diversity of outcomes that planetary formation and the subsequent evolution of the planetary systems can produce. The orbital and basic physical data we currently possess for the bulk of the exoplanet

Simultaneous Conduction and Valence Band Quantization in Ultrashallow High-Density Doping Profiles in Semiconductors

We demonstrate simultaneous quantization of conduction band (CB) and valence band (VB) states in silicon using ultrashallow, high-density, phosphorus doping profiles (so-called Si:P δ layers). We show that, in addition to the well-known quantization of CB states within the dopant plane, the confinement of VB-derived states between the subsurface P dopant layer and the Si surface gives rise to a si

Avfallsförebyggande handlar om effektiv produktion och genomtänkt konsumtion – inte om avfall. : Sju lärdomar från forskningsprojektet från avfallshantering till avfallsförebyggan

Denna rapport sammanfattar de viktigaste lärdomarna från forskningsprojektet ”Från avfallshantering till avfallsförebyggande”. I forskningsprojektet har forskare från Lunds universitet och Göteborgs universitet, men också Umeå Universitet och Kungliga Tekniska Högskolan, studerat avfallsförebyggande.Syftet med projektet har varit att identifiera och förklara svårigheterna med att förverkliga de av

Matrix Metalloproteinase-8 Activity is Increased in Type 1 Diabetes Children with High-Risk Diabetes HLA and Systemic Inflammation

Background: Matrix metalloproteinases (MMPs) and myeloperoxidase (MPO) are colocalized to lipid-laden macrophages, and play a central role in initiation and propagation of chronic vascular diseases including atherosclerosis. Prior cross-sectional studies from our centre on children and adolescents with type 1 diabetes suggested possible propensity conferred by diabetes-risk HLA DQ2/8, particularly

Streptococcus pneumoniae Otitis Media Pathogenesis and How It Informs Our Understanding of Vaccine Strategies.

Purpose of Review This study aimed to review the literature regarding the mechanisms of transition from asymptomatic colonization to induction of otitis media and how the insight into the pathogenesis of otitis media has the potential to help design future otitis media-directed vaccines. Recent Findings Respiratory viruses have long been shown to predispose individuals to bacterial respiratory inf

Thermal tolerance in the keystone species Daphnia magna—a candidate gene and an outlier analysis approach

Changes in temperature have occurred throughout Earth's history. However, current warming trends exacerbated by human activities impose severe and rapid loss of biodiversity. Although understanding the mechanisms orchestrating organismal response to climate change is important, remarkably few studies document their role in nature. This is because only few systems enable the combined analysis of ge

Streptococcus pneumoniae Modulates Staphylococcus aureus Biofilm Dispersion and the Transition from Colonization to Invasive Disease.

Streptococcus pneumoniae and Staphylococcus aureus are ubiquitous upper respiratory opportunistic pathogens. Individually, these Gram-positive microbes are two of the most common causative agents of secondary bacterial pneumonia following influenza A virus infection, and they constitute a significant source of morbidity and mortality. Since the introduction of the pneumococcal conjugate vaccine, r

Taxonomy of the Narcissus Flycatcher Ficedula narcissina complex : An integrative approach using morphological, bioacoustic and multilocus DNA data

The taxonomy of the Narcissus Flycatcher Ficedula narcissina-Yellow-rumped Flycatcher Ficedula zanthopygia complex from East Asia has long been debated. Most authors recognize two species: F. narcissina, with the subspecies narcissina (most of Japan and Sakhalin Island), owstoni (south Japanese islands) and elisae (northeast China) and F. zanthopygia (monotypic), although species status has been p

A European-wide 222radon and 222radon progeny comparison study

Although atmospheric 222radon (222Rn) activity concentration measurements are currently performed worldwide, they are being made by many different laboratories and with fundamentally different measurement principles, so compatibility issues can limit their utility for regional-to-global applications. Consequently, we conducted a European-wide 222Rn ∕ 222Rn progeny comparison study in order to eval
