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

Quasi diabatic CASSCF state functions

A new method to determine quasi diabatic (QD) CASSCF states is presented. The adiabatic states are subjected to a unitary transformation resulting from diagonalization of a state-selection operator. The latter is constructed from the overlap of the adiabatic states with a suitable set of reference states. The multi-state (MS) CASPT2 method is used to account for the dynamical correlation effects i

Biochar from cookstoves reduces greenhouse gas emissions from smallholder farms in Africa

Biochar produced in cookstoves has the potential to contribute to negative carbon emissions through sequestration of biomass carbon while also providing other benefits for sustainable development, including provision of clean renewable energy and increased yields in tropical agriculture. The aim of the reported research was to estimate effects on food production, household energy access and life c

Ny definition av palliativ vård med fokus på lidande

Palliative care was initially developed for patients with a cancer diagnosis and severe symptoms. Despite the ambition to broaden the palliative care approach to include other groups, patients with cancer are still a majority in specialised palliative care. The broader view and development of palliative care has led to an intense debate on existing definitions. Following a request from The Lancet

Long-term risk factors for suicide in suicide attempters examined at a medical emergency in patient unit : results from a 32-year follow-up study

OBJECTIVES: The overall aim of this study is to gain greater knowledge about the risk of suicide among suicide attempters in a very long-term perspective. Specifically, to investigate possible differences in clinical risk factors at short (≤5 years) versus long term (>5 years), with the hypothesis that risk factors differ in the shorter and longer perspective. DESIGN: Prospective study with regist

Cognitive Therapy for PTSD in Children and Adolescents

Children and adolescents exposed to traumatic events are at high risk of developing posttraumatic stress disorder (PTSD). With the rare exception of very young children, their PTSD presentations at the symptom level are similar to those of trauma-exposed adults, as are their patterns of psychiatric comorbidity, particularly for adolescents. Untreated, at least a significant proportion will carry o

Social media in the context of development : A case study of Dutch NGOs

This paper presents views of six Dutch development NGOs on possibilities and threats of social media for their work. A systematic analysis of the literature and the systematic analysis of the interviews yield an interesting theoretical framework in which social media characteristics are cross-referenced with NGO organisational characteristics. The resulting preliminary framework of emerging themes

Acoustic trapping based high throughput isolation and characterization of pathogen activated platelet derived extracellular vesicles from plasma

We present the use of a high capacity and high throughput acoustic trapping platform for phenotypic characterization and functional studies of extracellular vesicles (EVs) from pathogen activated platelets. Platelet rich plasma was stimulated with bacterial M1 protein isolated from S. Pyogenes, which is known to activate platelets. The subsequently released platelet EVs were isolated from 400 μL p

No title

In Denmark, the incidence of carbapenemase-producing organisms (CPO) is increasing, and a coordinated national strategy is needed. We describe a case story of a 40-year-old woman transferred to a Danish hospital with severe complications after cosmetic surgery in the Middle East. She had an intra-abdominal infection with three different CPO, one of them co-resistant to colistin, one of the few rem

Site selection for nature-based solutions for stormwater management in urban areas : An approach combining GIS and multi-criteria analysis

In recent years, particularly following the definition of the UN Sustainable Development Goals (SDGs) for 2030, Nature-Based Solutions (NBS) have gained considerable attention, capturing the interest of both the scientific community and policymakers committed to addressing urban environmental issues. However, the need for studies to guide decision-makers in identifying suitable locations for NBS i

Flow and noise investigations of a separate flow exhaust system

A major component of aircraft noise is the jet noise created by the high velocity hot stream exhausting from a jet engine, interacting with itself and with the surrounding cold air. In the present paper the flow and acoustic fields that are generated by two coaxial jets are considered. Numerically, the problem is divided into a flow related part (Navier-Stokes system of equation) and an acoustic p

Endothelium-specific ablation of PDGFB leads to pericyte loss and glomerular, cardiac and placental abnormalities

Platelet-derived growth factor-B (PDGFB) is necessary for normal cardiovascular development, but the relative importance of different cellular sources of PDGFB has not been established. Using Cre-lox techniques, we show here that genetic ablation of Pdgfb in endothelial cells leads to impaired recruitment of pericytes to blood vessels. The endothelium-restricted Pdgfb knockout mutants also develop

Traffic conflicts analyses for 2+1 road sections

The additional passing lanes and 2+1 roads improve significant road safety. Studies indicate sections with additional passing lanes (relief or alternately), which may cause reduction in the number of accidents by 50%. However, how geometric design affects the safety performance of such sections is not in depth investigated. Previous studies are carried out with two approaches, i.e. the most often,
