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

Development and Assessment of Users' Satisfaction with the Systemic Lupus Erythematosus Disease Activity Index 2000 Responder Index-50 Website.

OBJECTIVE: To describe the development of the Systemic Lupus Erythematosus Disease Activity Index 2000 Responder Index-50 (S2K RI-50) Website (www.s2k-ri-50.com) and to assess satisfaction with its training and examination modules among rheumatologists and rheumatology fellows. METHODS: The development of the Website occurred in 3 phases. The first was a deployment phase that consisted of preparin

Large fat and skin necroses after deep subcutaneous injections of a slow-release somatostatin analogue in a woman with acromegaly.

OBJECTIVE: Somatostatin analogues are the most commonly used drugs for treatment of acromegaly. Known side effects include gastrointestinal reactions, cholelithiasis, effects on glucose metabolism, and mild reactions at injection sites. We report a patient who developed fat and skin necroses after injections of a depot somatostatin analogue. SUBJECT: A woman with active acromegaly was given deep s

Influence of Maternal and Paternal Birthweight on Offspring Birthweight - a Population-based Intergenerational Study.

The correlation between infant birthweight and parental birthweight has received substantial interest. However, fewer studies including the birthweight of the father have had access to large sets of population-based data. The objective of this study is to examine the influence of maternal and paternal birthweight on the birthweight of the offspring in the context of other birthweight determinants,

The future of incretin-based therapy: novel avenues-novel targets.

Incretin-based therapy for type 2 diabetes is based on the antidiabetic effects of glucagon-like peptide-1 (GLP-1) and instituted by GLP-1 receptor agonists and dipeptidyl peptidase-4 inhibitors targeting the key islet defects of the disease. The treatment is clinically efficient and safe, and associated with a low risk of adverse events. It can be used both in early and late stages of the disease

Recognition memory for emotional and neutral faces: An event-related potential study

This study examined emotional influences on the hypothesized event-related potential (ERP) correlates of familiarity and recollection (Experiment 1) and the states of awareness (Experiment 2) accompanying recognition memory for faces differing in facial affect. Participants made gender judgments to positive, negative, and neutral faces at study and were in the test phase instructed to discriminate

Extensive dinoflagellate phylogenies indicate infrequent marine-freshwater transitions

We have constructed extensive 18S–28S rDNA dinoflagellate phylogenies (>200 sequences for each marker) using Maximum Likelihood and Bayesian Inference to study the evolutionary relationships among marine and freshwater species (43 new sequences). Our results indicated that (a) marine and freshwater species are usually not closely related, (b) several freshwater species cluster into monophyletic gr

Mercury degassing rate from mineralized areas in the Mediterranean basin

Knowledge of the natural emissions of mercury in the Mediterranean basin, which has large cinnabar anomalies, has particular weight as these deposits could be an important source of atmospheric mercury. Data on the degassing rate of mercury from soils sampled both in mineralized areas (Mt. Amiata, Italy and Almaden, Spain) and rural areas are reported. Measurements were carried out 'in situ' using

Preparation of primary microglia cultures from postnatal mouse and rat brains.

Microglia are the inflammatory cells of the brain and are activated in neuropathological conditions. To study the biology of microglia, these cells can be isolated from the brain and analyzed in terms of pro- and anti-inflammatory cytokine production, involvement of intracellular signaling pathways upon inflammatory stimuli, phagocytosis, and several more biological aspects to understand their rol
