The role of phospholipid transfer protein in lipoprotein-mediated neutralization of the procoagulant effect of anionic liposomes.

Summary Background: Serum has the ability to neutralize the procoagulant properties of anionic liposomes, with transfer of phospholipids (PLs) to both high-density lipoprotein (HDL) and low-density lipoprotein (LDL) particles. Phospholipid transfer protein (PLTP) mediates transfer of PLs between HDL and other lipoproteins and conversion of HDL into larger and smaller particles. Objectives: To exam

Multicomponent Moraxella catarrhalis outer membrane vesicles induce an inflammatory response and are internalized by human epithelial cells.

Moraxella catarrhalis is an emerging human respiratory pathogen in patients with chronic obstructive pulmonary disease (COPD) and in children with acute otitis media. The specific secretion machinery known as outer membrane vesicles (OMVs) is a mechanism by which Gram-negative pathogens interact with host cells during infection. We identified 57 proteins in M. catarrhalis OMVs using a proteomics a

Heart failure diagnostics based on ventilation/perfusion single photon emission computed tomography pattern and quantitative perfusion gradients.

OBJECTIVE: Left heart failure (LHF) is a common and frequently overlooked condition owing to insufficient diagnostic methods. This can potentially delay onset of treatment. Our clinical experience with ventilation/perfusion single photon emission computed tomography (V/P SPECT) indicates that perfusion shows an antigravitational distribution pattern in LHF. The aim of the study was to test the hyp

Thymic stromal lymphopoietin exerts antimicrobial activities.

Thymic stromal lymphopoietin (TSLP) is an interleukin-7-like cytokine expressed by epithelial cells and reported to be involved in allergic diseases and atopic eczema. The presence of several predicted α-helical regions in TSPL, a structure characterizing many classical antimicrobial peptides (AMPs), prompted us to investigate whether TSLP exerts antimicrobial activities. Recombinant human TSLP ex

Metabolic control, healthcare satisfaction and costs 1 month after diagnosis of type 1 diabetes: a randomised controlled trial of hospital-based care vs. hospital-based home care.

Procedures for the initial management of children newly diagnosed with diabetes vary greatly worldwide and the evidence available is insufficient for conclusively determining the best process regarding hospital-based or home-based care. The aim of the study was to compare two different regimens for children with newly diagnosed type 1 diabetes; hospital-based care and hospital-based home care (HBH

Nordic Seniors on the Move : Mobility and Migration in Later Life

"I believe that all people need to move about. Actually, some have difficulties in doing so. They stay in their home neighbourhoods, where they’ve grown up and feel safe. I can understand that, but my wife and I, we didn’t want that. We are more open to new ideas".This anthology is about seniors on the move. In seven chapters, Nordic researchers from various disciplines, by means of ethnographic m

Binding of albumin promotes bacterial survival at the epithelial surface.

Albumin (HSA) is the dominating protein in human plasma. Many bacterial species, especially streptococci, express surface proteins that bind HSA with high specificity and affinity, but the biological consequences of these protein-protein interactions are poorly understood. Group G streptococci (GGS), carrying the HSA-binding protein G, colonize the skin and the mucosa of the upper respiratory trac

Signal transduction pathways of muscarinic receptor mediated activation in the newborn and adult mouse urinary bladder.

OBJECTIVE To study the role of M(2) and M(3) muscarinic receptor subtypes, sources of activator Ca(2+), and mechanisms involved in increased force oscillations in muscarinic contractions in the bladders of newborn and adult mice, as in the adult bladder muscarinic M(3) receptors are considered to mediate the main part of bladder contraction, and this has not been established in the newborn bladder

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

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

Mast-cell-dependent secretion of CXC chemokines regulates ischemia-reperfusion-induced leukocyte recruitment in the colon.

BACKGROUND AND AIMS: Recruitment of leukocytes in the tissue microvasculature is considered to be a rate-limiting step in ischemia-reperfusion (I/R)-induced inflammation. The objective of this study was to examine the role of mast cells in CXC-chemokine- and I/R-provoked leukocyte recruitment in the colon. MATERIALS AND METHODS: Balb/c- and mast-cell-deficient mice were challenged with the CXC che

Three-dimensional inverse scattering: layer-stripping formulas and ill-posedness results

The authors consider the three-dimensional direct and inverse scattering problems for the Schrodinger equation and for the reduced wave equation with variable velocity. The scatterer is probed with either point sources or plane waves of fixed frequency. They ask the question, 'How does the wave field change when the scatterer is truncated?' Simple formulae for the derivative of the wave field with

Amphetamine-induced abnormal movements occur independently of both transplant- and host-derived serotonin innervation following neural grafting in a rat model of Parkinson's disease.

Serotonin has been postulated to play a role in the transplant-induced involuntary movements that occur following intrastriatal grafts of ventral mesencephalic tissue in the treatment of Parkinson's disease. Serotonin innervation of the striatum may be derived from either the donor graft tissue or the normal host projections from the midbrain. In two sets of experiments we study the impact of graf
