Cartilage oligomeric matrix protein deficiency promotes early onset and the chronic development of collagen-induced arthritis.

ABSTRACT: INTRODUCTION: Cartilage oligomeric matrix protein (COMP) is a homopentameric protein in cartilage. The development of arthritis, like collagen-induced arthritis (CIA), involves cartilage as a target tissue. We have investigated the development of CIA in COMP-deficient mice. METHODS: COMP-deficient mice in the 129/Sv background were backcrossed for 10 generations against B10.Q mice, which

Population pharmacokinetic modeling for dose setting of nonacog beta pegol (N9-GP), a glycoPEGylated recombinant factor IX.

Background: nonacog beta pegol (N9-GP) is a glycoPEGylated recombinant factor IX (rFIX) molecule with a prolonged half-life. Objectives: To provide information on potential dose regimens for N9-GP for phase 3 pivotal and surgery trials. Methods: A population pharmacokinetic model was developed from single-dose data derived from the first human dose trial with N9-GP in hemophilia B patients, and wa

An electromechanically coupled micro-sphere framework: application to the finite element analysis of electrostrictive polymers

The number of industrial applications of electroactive polymers (EAPs) is increasing and, consequently, the need for reliable modelling frameworks for such materials as well as related robust simulation techniques continuously increases. In this context, we combine the modelling of non-linear electroelasticity with a computational micro-sphere formulation in order to simulate the behaviour of EAPs

Covariation of plasma ghrelin and motilin in irritable bowel syndrome.

We have previously shown that ghrelin is mainly localized to the stomach but also occurs, together with the prokinetic hormone motilin, in endocrine cells in the proximal small intestine. This study explored ghrelin and motilin concentrations in plasma in relation to gastrointestinal motility and whether plasma ghrelin is changed in patients with irritable bowel syndrome (IBS). Nine patients with

Young women choosing contraceptives : stories about information literacy practices related to evaluation and use of information sources

I artikeln presenteras delresultat från ett doktorand-projekt om informationskompetenspraktiker i svenskt vardagsliv: unga kvinnors (18-23 år) informations-kompetenspraktiker när de väljer preventivmedel. Syftet är att förstå de unga kvinnornas perspektiv som det kommer till uttryck i deras berättelser om val och värdering av informationskällor om preven-tivmedel.En metod inspirerad av narrativa iResults from a PhD project of information literacy practices in a Swedish everyday life setting are presented; how young women (aged 18-23 years) involve in information literacy practices when choosing a contraceptive. The aim of this article is to understand the young women’s perspective, expressed in stories about their sources and how they evaluated these before making the choice. Method inspir

Seven Categories of Constitutional Critical Judging: An Interpretation of Nordic Case-Law

In Danish literature from the early 1970s, it was suggested that the freedom of speech should have a preferred position in relation to other constitutional rights. In a case from the Norwe-gian Supreme Court in 1976, judicial review of the constitutionality of legislation was divided in three categories. Constitutional rules about the freedom and security of the individual should be supervised mos

Dopamine neuron precursors within the developing human mesencephalon show radial glial characteristics.

Specification and differentiation of neural precursors into dopaminergic neurons within the ventral mesencephalon has been subject to much attention due to the implication of dopaminergic neurons in Parkinson's disease and the perspective of generating sources of therapeutically active cells to be used for cell replacement therapy for the disease. However, despite intensive research efforts, littl

Is cartilage sGAG content related to early changes in cartilage disease? Implications for interpretation of dGEMRIC.

OBJECTIVE: This study investigates sulphated glycosaminoglycans (sGAG) content changes in early osteoarthritis (OA), and whether contrast-enhanced magnetic resonance imaging (MRI) of cartilage in vitro may identify early event of OA pathology. METHOD: Osteochondral plugs from patients with hip OA or femoral neck fracture (reference group) were collected and analysed by 1.5 T MRI with ΔR1 as a me

The Experience of Care at Nurse-Led Rheumatology Clinics.

OBJECTIVE: To describe how people with rheumatoid arthritis (RA) experience the care provided by Swedish nurse-led rheumatology outpatient clinics. METHODS: Eighteen adult people with a diagnosis of RA who had had at least three documented contact sessions with a nurse-led clinic were interviewed. The interviews were analysed with qualitative content analysis. RESULTS: Care was expressed in

Defining targets for complement components C4b and C3b on the pathogenic neisseriae

Complement is a key arm of the innate immune defenses against the pathogenic neisseriae. We previously identified lipooligosaccharide on Neisseria meningitidis as an acceptor for complement C4b. Little is known about other neisserial targets for complement proteins C3 and C4, which covalently attach to bacterial surfaces and initiate opsonization and killing. In this study we demonstrate that N. g

Rationale for multiple risk intervention: the need to move from theory to practice.

Incidence of cardiovascular (CV) and metabolic disease is increasing, in parallel with associated risk factors. These factors, such as low-density lipoprotein (LDL)-cholesterol, elevated blood pressure, obesity, and insulin resistance have a continuous, progressive impact on total CV risk, with higher levels and numbers of factors translating into greater risk. Evaluation of all known modifiable r

Heterogeneity of Collagen VI Microfibrils: Structural Analysis of Non-collagenous Regions.

Collagen VI, a collagen with uncharacteristically large N- and C-terminal non-collagenous regions, forms a distinct microfibrillar network in most connective tissues. It was long considered to consist of three genetically distinct α chains (α1, α2 and α3). Intracellularly heterotrimeric molecules associate to form dimers and tetramers, which are then secreted and assembled to microfibrils. The ide

Anionic Phospholipids Lose their Procoagulant Properties when Incorporated into High-Density Lipoproteins.

Blood coagulation involves a series of enzymatic protein complexes that assemble on the surface of anionic phospholipid. To investigate whether apolipoproteins affect coagulation reactions, they where included during the preparation of anionic phospholipid vesicles using a detergent solubilization-dialysis method. Apolipoprotein components of high-density lipoproteins, especially apolipoprotein A-

Mutant huntingtin causes metabolic imbalance by disruption of hypothalamic neurocircuits.

In Huntington's disease (HD), the mutant huntingtin protein is ubiquitously expressed. The disease was considered to be limited to the basal ganglia, but recent studies have suggested a more widespread pathology involving hypothalamic dysfunction. Here we tested the hypothesis that expression of mutant huntingtin in the hypothalamus causes metabolic abnormalities. First, we showed that bacterial a

SATB2 in Combination With Cytokeratin 20 Identifies Over 95% of all Colorectal Carcinomas.

The special AT-rich sequence-binding protein 2 (SATB2), a nuclear matrix-associated transcription factor and epigenetic regulator, was identified as a tissue type-specific protein when screening protein expression patterns in human normal and cancer tissues using an antibody-based proteomics approach. In this respect, the SATB2 protein shows a selective pattern of expression and, within cells of e

Visible-Uv fluorescence studies of fragments resulting from the relaxation of molecular core hole states

The absorption of soft x-ray radiation induces neutral and ionic core hole states in molecules. The relaxation of such states typically leads to a multi-step process, at the end of which photons in the visible and UV range can also be emitted from fragments. In this paper, we present results on Balmer and Lyman emission that originates from excited H atoms produced at the K-edge of the water, ammo
