Nanodiscs are self-assembled nanostructures composed of a belt protein and a small patch of lipid bilayer, which can solubilize membrane proteins in a lipid bilayer environment. We present a method for the alignment of a well-defined two-dimensional layer of nanodiscs at the air-water interface by careful design of an insoluble surfactant monolayer at the surface. We used neutron reflectivity to d

The production of nitrogen fertilizers are almost exclusively based on fossil feedstocks such as natural gas and coal. Nitrogen fertilizers are a necessity to maintain the high agricultural production that the world's population currently demands. Ammonia produced from nonfossil-based feedstocks would enable renewable production of ammonia. Renewable feedstocks are one thing, but perhaps even more

Background: To study the diabetes related CVD risk between men and women of different ages. Methods: Hazards ratios (HRs) (95%CI) for acute CHD and ischaemic stroke events were estimated based on data of Finnish and Swedish cohorts of 5111 women and 4167 men. Results: 182 (3.6%) women and 348 (8.4%) men had CHD and 129 (2.5%) women and 137 (3.3%) men ischaemic stroke events. The multivariate adjus

In this overview the technique of accelerator mass spectrometry (AMS) and its use are described. AMS is a highly sensitive method of counting atoms. It is used to detect very low concentrations of natural isotopic abundances (typically in the range between 10(-12) and 10(-16)) of both radionuclides and stable nuclides. The main advantages of AMS compared to conventional radiometric methods are the

The role of nitric oxide (NO) in migraine has been studied in the experimental glyceryl trinitrate (GTN)-infusion headache model. We hypothesized that GTN-induced headache may activate the trigeminovascular system and be associated with increased levels of sensory neuropeptides, including calcitonin gene-related peptide (CGRP). CGRP, vasoactive intestinal peptide (VIP), neuropeptide Y (NPY) and so

Background: Plasma use has increased since studies have suggested that early treatment with blood components in trauma with severe hemorrhage may improve outcome. Plasma is also commonly used to correct coagulation disturbances in non-bleeding patients. Little is known about the effects of plasma transfusion on plasma volume. We report a prospective interventional study in which the plasma volume-

Objective To describe the experiences of people with systemic sclerosis (SSc) in different European countries of functioning and health and to link these experiences to the WHO International Classification of Functioning, Disability and Health (ICF) to develop a common understanding from a bio-psycho-social perspective. Method A qualitative multicentre study with focus-group interviews was perform

The REVEALS model was developed to reconstruct quantitatively regional vegetation abundance (in a 10(4)-10(5) km(2) area) from pollen assemblages in large lakes (>= 100-500 ha). This model corrects for biases in pollen percentages caused by inter-taxonomic differences in pollen productivity and dispersal. This paper presents the first case study to validate REVEALS, using empirical data from south

Objective: To explore the natural course of knee osteoarthritis (OA) in a middle-aged population with chronic knee pain. Methods: A population-based sample of 143 subjects (mean age 45 (range 35-54), 44% women) with knee pain (>3 months) at inclusion was studied. Weightbearing posteroanterior tibiofemoral (TF) radiographs were obtained at baseline and 12 years later, and classified according to Ke

To describe incidence, risk factors, and influence of treatment on occurrence of central nervous system (CNS) relapse or progression in younger patients with aggressive B-cell lymphoma. We analyzed 2210 patients with aggressive B-cell lymphoma treated on various studies for CNS relapse/progression. Treatment consisted of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) +/- etoposi

Increasing precipitation and surface water temperature due to global change may strengthen the salinity gradient in coastal regions, which could influence the behaviour of dinoflagellate migration. We studied diel vertical migration (DVM) behaviour in the dinoflagellates Prorocentrum minimum and Heterocapsa triquetra using vertically stratified laboratory columns with 3 different salinity gradient

Background: To explore the point prevalence of the risk of malnutrition and the targeting of nutritional interventions in relation to undernutrition risk and hospital volume. Methods: A cross-sectional survey performed in nine hospitals including 2 170 (82.8%) patients that agreed to participate. The hospitals were divided into large, middle, and small sized hospitals. Undernutrition risk and over

Persistent severe swallowing dysfunction with aspiration is a common and sometimes overlooked sequelae after treatment for squamous cell carcinoma of the head and neck (SCCHN) and may impact food intake and nutritional status. More knowledge is needed to increase the understanding of severe swallowing dysfunction as a risk factor for persistent nutritional deteriorations in SCCHN survivors. The pu

Purpose - The purpose of this paper is to investigate to what extent male and female PhDs choose academic vs non-academic employment. Further, it analyses gender earnings differences in the academic and non-academic labour markets. Design/methodology/approach - Rich Swedish cross-sectional register data on the stock of PhDs in 2004 is used for investigating differences between male and female PhDs

Hormone-sensitive lipase (HSL), a key enzyme in fatty acid mobilization in adipocytes, has been demonstrated also in skeletal muscle. To gain further insight into the role and importance of HSL in skeletal muscle, a transcriptome analysis of soleus muscle of HSL-null mice was performed. A total of 161 transcripts were found to be differentially expressed. Increased mRNA levels of fructose-1,6-bisp

OBJECTIVE: To determine and analyse the incidence of childhood injuries in Reykjavik 1974-1991. DESIGN: Descriptive, retrospective study. SETTING: Reykjavik City district with a mean number of 88700 inhabitants, of which 23.4% were children under 15 years of age. SUBJECTS: All children 0-14 years old who came to the emergency department at Reykjavik City Hospital because of an injury. MAIN OUTCOME

The objective of the study was to investigate whether spontaneous and iatrogenic preterm births are associated with different paediatric outcomes. A nationwide population-based study comprising 1 010 487 singletons used data from 1991 to 2001 from the Swedish Medical Birth Register and the Swedish Hospital Discharge Register. Intrauterine fetal deaths, unknown type of delivery onset and congenital
