Defective paracrine signalling by TGF beta in yolk sac vasculature of endoglin mutant mice: a paradigm for hereditary haemorrhagic telangiectasia

Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant disorder in humans that is characterised by multisystemic vascular dyplasia and recurrent haemorrhage. Germline mutations in one of two different genes, endoglin or ALK1 can cause HHT. Both are members of the transforming growth factor (TGF) beta receptor family of proteins, and are expressed primarily on the surface of endothel

The vasorelaxant effect of adrenomedullin, proadrenomedullin N-terminal 20 peptide and amylin in human skin

In this study we aimed to assess in vivo, the vasodilator effects of adrenomedullin, proadrenomedullin N-terminal 20 peptide (PAMP) and amylin in human skin vasculature and compare the responses to the effects mediated by the endogenenous neuropeptides calcitonin gene-related peptide (CGRP) and substance P and to examine the mRNA expression of calcitonin receptor-like receptor (CL-R) and receptor-

Densities and viscosities of mono(ethylene glycol) plus 2-amino-2-methyl-1-propanol plus Water

The densities and viscosities of ternary mixtures of mono(ethylene glycol) (MEG) + 2-amino-2-methyl-1-propanol (AMP) + water have been measured at temperatures of 25 to 40 degreesC. The water content varied in the range 1.4 to 15.6 mol %, and the amine concentration varied from 0 to 11.8 mol %. The excess volumes were calculated from the experimental data and fitted to a simple Redlich-Kister type

Muscle strength, functional performance, and self-reported outcomes four years after arthroscopic partial meniscectomy in middle-aged patients.

Objective. To examine thigh muscle strength, functional performance, and self-reported outcome in patients with nontraumatic meniscus tears 4 years after operation, and to study the impact of a strength deficit on self-reported outcome and evaluate the feasibility of 3 performance tests in this patient group. Methods. The study group comprised 45 patients (36% women, mean age 46.7) who had an arth

Bayesian inference of evolutionary history from chloroplast microsatellites in the cosmopolitan weed Capsella bursa-pastoris (Brassicaceae)

Besides showing an extraordinary degree of phenotypic variability, Capsella bursa-pastoris (Brassicaceae) is also one of the world's most common plant species and a serious weed in many countries. We have employed a coalescent-based Bayesian analysis of chloroplast microsatellite data to infer demographic and evolutionary parameters of this species. Two different demographic models applied to data

Observed parental needs during their child’s hospitalization

Hospitalization involves that parents are in an unfamiliar environment and their parental role changes. The purpose of this study was to study parental needs during the course of events when their child is hospitalized. Thirty-five parents of 24 children (aged 5 months to 18 years) were followed by observers during their child's hospitalization at a pediatric department in Sweden. Field notes were

Infection prevention at day-care centres: Feasibility and possible effects of intervention

Objective. To study the effect of an educationally oriented intervention programme, with the recommendations from the National Board of Health and Welfare as a base. Design. A prospective intervention study. Setting. Six day-care centres in Vaxjo, Sweden. Three centres comprised the intervention group and three constituted the control group. Subjects and main outcome measures. The parents and pers

Endothelial P2Y receptors induce hyperpolarisation of vascular smooth muscle by release of endothelium-derived hyperpolarising factor

The effects of P2Y receptor agonists on smooth muscle membrane potential in isolated ring segments of rat mesenteric artery were examined by intracellular microelectrodes. In the presence of inhibitors of nitric oxide-synthase and cyclo-oxygenase, the selective P2Y1 receptor agonist adenosine 5'-O-thiodiphosphate (ADPbetaS) induced endothelium-dependent membrane hyperpolarisations, which were abol

CHOP is superior to CNOP in elderly patients with aggressive lymphoma while outcome is unaffected by filgrastim treatment: results of a Nordic Lymphoma Group randomized trial

This study was designed to test the hypothesis that administration of granulocyte colony-stimulating factor (G-CSF; filgrastim) during induction chemotherapy with CHOP (cyclophosphamide, vincristine, doxorubicin, prednisone) or CNOP (doxorubicin replaced with mitoxantrone) in elderly patients with aggressive non-Hodgkin lymphoma (NHL) improves time to treatment failure (TTF), complete remission (C

Malaria primes the innate immune response due to interferon-gamma induced enhancement of toll-like receptor expression and function

Malaria-induced sepsis is associated with an intense proinflammatory cytokinemia for which the underlying mechanisms are poorly understood. It has been demonstrated that experimental infection of humans with Plasmodium falciparum primes Toll-like receptor (TLR)-mediated proinflammatory responses. Nevertheless, the relevance of this phenomenon during natural infection and, more importantly, the mec

Analysis of dose distribution in the 'Rind' - a volume outside the PTV - in 3-dimensional conformal radiation therapy of non-small cell lung cancer

Background and purpose: Appropriate planning target volume (PTV) definition is critical for local disease eradication in the treatment of non-small cell lung cancer (NSCLC). When margins are added to the gross tumour volume (GTV) in the standard way, the PTV formed may be too large to facilitate dose escalation due to normal tissue tolerance. To increase the feasibility of dose escalation with 3-d

Correlation spectroscopy of excitons and biexcitons on a single quantum dot

We report the observation of antibunched emission from single self-assembled InAs quantum dots under various conditions. We have measured the correlation function of the photon emission pertaining to single emission lines from single quantum dots under continuous and pulsed laser excitation, as well as under continuous white light excitation. The measurements were performed under different excitat

Confirming the three-factor structure of the Disgust Scale-Revised in eight countries

The current study evaluates the factor structure of the Disgust Scale-Revised (DS-R) in eight countries: Australia, Brazil, Germany, Italy, Japan, the Netherlands, Sweden, and the United States (N = 2,606). Confirmatory factor analysis is used to compare two different models of the DS-R and to investigate the invariance of the factor structure of the DS-R across countries and gender. A three-facto

Platinum group elements and Os-187/Os-188 in a purported impact ejecta layer near the Eifelian-Givetian stage boundary, Middle Devonian

A global faunal crisis close to the Eifelian-Givetian stage boundary in the mid-Devonian has been purported to be related to the impact of one or two major extraterrestrial bodies. This was based on unusual mineralogical and chemical features within a distinct composite marl bed, at a level c. 40 cm below the Global Stratotype Section and Point (GSSP) for the Eifelian-Givetian boundary at Jebel Me

Osteopenia in alcoholics after tibial shaft fractures

A marked reduction of 40-70% in regional bone mineral density (BMD) has been reported after fractures of long bones, and this post-traumatic osteopenia may to some extent persist for several years, perhaps lifelong. In this cross-sectional study, we investigated whether prolonged alcohol abuse had any effect on the degree of post-traumatic osteopenia after isolated tibia shaft fractures, the ratio

Ontologies and construals in lexical semantics

The purpose of this paper is to propose a framework of lexical meaning, broadly along the lines of Cognitive Semantics (Langacker 1987). Within the proposed model, all aspects of meaning are to be explained in terms of properties of ontologies in conceptual space, i.e. properties of content ontologies and schematic ontologies and construals which are imposed on the conceptual structures on the occ
