Natural history of radiographic features of hand osteoarthritis over 10 years

Objectives: To evaluate the natural history of radiographic hand osteoarthritis (OA) over 10 years. Design: We assessed 118 subjects (30 women) twice (X-ray A and B) with mean (SD) follow-up time of 9.6 (0.4) years. Subjects were of mean (SD) age 52 (10) years at X-ray A and had undergone prior knee meniscectomy. Radiographs of the distal interphalangeal (DIP) and proximal interphalangeal (PIP) jo

Effects of changing exposure to neighbourhood greenness on general and mental health: A longitudinal study.

Green neighbourhood environments have been associated with physical and psychological wellbeing in adults. Access to greenness is potentially more important in vulnerable subgroups. In this study based on longitudinal survey data from southern Sweden the cohort was divided into prognostic groups for good self-reported general (n=8891) and mental (n=9444) health. We used independent survey data to

Computational visual ecology in the pelagic realm.

Visual performance and visual interactions in pelagic animals are notoriously hard to investigate because of our restricted access to the habitat. The pelagic visual world is also dramatically different from benthic or terrestrial habitats, and our intuition is less helpful in understanding vision in unfamiliar environments. Here, we develop a computational approach to investigate visual ecology i

Measurements of normalized differential cross sections for t(t)over-bar production in pp collisions at root(s)=7 TeV using the ATLAS detector

Measurements of normalized differential cross sections for top-quark pair production are presented as a function of the top-quark transverse momentum, and of the mass, transverse momentum, and rapidity of the t (t) over bar system, in proton proton collisions at a center-of-mass energy of root s = 7 TeV. The data set corresponds to an integrated luminosity of 4.6 fb(-1), recorded in 2011 with the

Thermal Fluid-Structure-Interaction - Experimental and Numerical Analysis

In the present paper the thermal fluid-structure-interaction is experimentally and numerically investigated. Therefore, the interaction phenomena is modeled by the Reynolds-averaged Navier-Stokes equations and the nonlinear Fourier heat conduction equation are used for the fluid and the solid phase, respectively. The simulation is performed using a partitioned approach using the finite volume meth

Electrospun carbon nanofibers from polyacrylonitrile blended with activated or graphitized carbonaceous materials for improving anodic bioelectrocatalysis.

The electrospun carbon nanofibers obtained from polyacrylonitrile (PAN) and PAN blends with either activated carbon (PAN-AC) or graphite (PAN-GR) were tested as anodes using Shewanella oneidensis MR-1. Extensive physico-chemical and electrochemical characterization confirmed their formation, their fibrous and porous nature, and their suitability as electrodes. N(2) adsorption measurements revealed

High performance MRI simulations of motion on multi-GPU systems

Background: MRI physics simulators have been developed in the past for optimizing imaging protocols and for training purposes. However, these simulators have only addressed motion within a limited scope. The purpose of this study was the incorporation of realistic motion, such as cardiac motion, respiratory motion and flow, within MRI simulations in a high performance multi-GPU environment. Method

Experiences of a Mental Health First Aid Training Program in Sweden: A Descriptive Qualitative Study.

Restricted mental health literacy and stigma are barriers to treatment of mental disorders. A Mental Health First Aid training program was tested for implementation in Sweden among employees in the public sector. The aim of the present qualitative study was to explore participants' experiences of the program in more depth, in conjunction with a randomized controlled study. Twenty four persons part

Photoinduced Electron Transfer in Organic Solar Cells.

Electron transfer (ET) is the key process in light-driven charge separation reactions in organic solar cells. The current review summarizes the progress in theoretical modelling of ET in these materials. First we give an account of ET, with a description originating from Marcus theory. We systematically go through all the relevant parameters and show how they depend on different material propertie

Convergence and specificity in the Arabidopsis MAPK nexus

Although mitogen-activated protein kinase (MAPK) signal transduction cascades are known regulators of various aspects of plant biology, our knowledge of these systems has been largely restricted to a small subset of the MAPKs. However, global analyses are now revealing that many more of these kinases are probably engaged in modulating developmental and fitness adaptation processes in the plant kin

Soluble urokinase plasminogen activator receptor in plasma is associated with incidence of CVD. Results from the Malmö Diet and Cancer Study.

BACKGROUND: Soluble urokinase plasminogen activator receptor (suPAR) is a highly sensitive marker that reflects increased inflammation and is positively correlated with pro-inflammatory biomarkers. The aim of this study was to explore the relationship between suPAR, cardiovascular disease (CVD) risk factors and incidence of CVD. METHODS: suPAR was assessed in a random sample of participants (N=569

Ethical interruption and the creative process - A reflection on the new

Both organizations and management theory seem obsessed with creativity and 'the new,' but lately, the 'newness' of this so-called 'new' has also been questioned. With this paper, I continue in this critical fashion and point to the peculiar fact that the obsession with the new is accompanied by just as strong a rejection of that which is different. Overcoming this paradox, the paper emphasizes the

Neonatal and maternal outcomes comparing women undergoing two in vitro fertilization (IVF) singleton pregnancies and women undergoing one IVF twin pregnancy

Objective: To compare outcomes for women undergoing two in vitro fertilization (IVF) pregnancies with singletons and women undergoing one IVF twin pregnancy. The concept of single-embryo transfer in IVF has reduced the risks of both maternal and neonatal complications, but there is still a discussion of whether or not twins are a desired outcome of IVF. Design: Registry study. Setting: Not applica

Incidence of fractures causing hospitalisation in prostate cancer patients: Results from the population-based PCBaSe Sweden

Background: Prostate cancer patients have an increased risk of fractures as a consequence of skeletal metastases and osteoporosis induced by endocrine treatment. Data on incidence of fractures and risks in subgroups of men with prostate cancer are sparse. Our aim with this study is to report the risk of fractures among men with prostate cancer in a nationwide population-based study. Patients and m

Synapsins I and II Are Not Required for Insulin Secretion from Mouse Pancreatic beta-cells

Synapsins are a family of phosphoproteins that modulate the release of neurotransmitters from synaptic vesicles. The release of insulin from pancreatic beta-cells has also been suggested to be regulated by synapsins. In this study, we have utilized a knock out mouse model with general disruptions of the synapsin I and II genes [synapsin double knockout (DKO)]. Stimulation with 20 mM glucose increa

Nonsuicidal self-injury in a community sample of adolescents: Subgroups, stability, and associations with psychological difficulties

Patterns of nonsuicidal self-injury (NSSI) and their association with other psychological difficulties were studied in a community sample of young Swedish adolescents, by a 2-wave longitudinal design with a 1-year interval. Hierarchical cluster analysis at T1 identified eight NSSI subgroups in each gender, of which five were clearly replicated at T2. Among these were a subgroup with generalized hi

Tibial coverage, meniscus position, size and damage in knees discordant for joint space narrowing - data from the Osteoarthritis Initiative

Introduction: Meniscal extrusion is thought to be associated with less meniscus coverage of the tibial surface, but the association of radiographic disease stage with quantitative measures of tibial plateau coverage is unknown. We therefore compared quantitative and semi-quantitative measures of meniscus position and morphology in individuals with bilateral painful knees discordant on medial joint

Fast Surface Acoustic Wave-Matrix-Assisted Laser Desorption Ionization Mass Spectrometry of Cell Response from Islets of Langerhans.

A desire for higher speed and performance in molecular profiling analysis at a reduced cost is driving a trend in miniaturization and simplification of procedures. Here we report the use of a surface acoustic wave (SAW) atomizer for fast sample handling in matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) peptide and protein profiling of Islets of Langerhans, for future type
