External losses in photoemission from strongly correlated quasi-two-dimensional solids

Expressions are derived for photoemission, which allow experimental electron energy loss data to be used for estimating losses in photoemission. The derivation builds on new results for dielectric response and mean free paths of strongly correlated systems of two-dimensional layers. Numerical evaluations are made for Bi2Sr2CaCu2O8 (Bi2212) by using a parametrized loss function. The mean free path

A comparison of the Nottingham Health Profile and Short Form 36 Health Survey in patients with chronic lower limb ischaemia in a longitudinal perspective

BACKGROUND: Different generic quality of life instruments such as the Nottingham Health Profile (NHP) and the Short Form 36 Health Survey (SF-36) have revealed conflicting results in patients with chronic lower limb ischaemia in psychometric attributes in short-term evaluations. The aim of this study was to compare the NHP and the SF-36 regarding internal consistency reliability, validity, respons

Investigations of human EEG response to viewing fractal patterns.

Owing to the prevalence of fractal patterns in natural scenery and their growing impact on cultures around the world, fractals constitute a common feature of our daily visual experiences, raising an important question: what responses do fractals induce in the observer? We monitored subjects’ EEG while they were viewing fractals with different fractal dimensions, and the results show that significa

Parental participation in pediatric surgical care

Hospitalization and surgery are stressful experiences for children and their parents. In recent years, pediatric health care has shifted toward family-centered care that is based on close and continuous involvement of the child's family members. To shape and improve how pediatric care is delivered, health care providers need to know what children and parents need, expect, and experience. Such know

Preferential conduction patterns along the coronary sinus during atrial fibrillation in humans and their modification by pulmonary vein isolation.

INTRODUCTION: Correlation function analysis applied to endocardial electrograms has earlier been used for analysis of agreement between signals and direction of activation during atrial fibrillation (AF). This study was aimed at evaluating whether preferential activation patterns along the coronary sinus (CS) exist in patients with AF. METHODS: Twenty-seven patients (57 ± 10 years old) admitted fo

Lower gastrointestinal bleeding: incidence, etiology, and outcomes in a population-based setting.

OBJECTIVES: To investigate the incidence and outcomes of acute lower gastrointestinal bleeding (ALGIB) in a population-based setting and examine the role of drugs potentially associated with GIB. METHODS: The study was prospective and population based. The cohort included all patients who underwent colonoscopy during the year 2010 at the National University Hospital of Iceland. Indications for

α 1-antitrypsin enhances insulin secretion and prevents cytokine-mediated apoptosis in pancreatic β-cells.

α1-antitrypsin (AAT) is a serine protease inhibitor, which recently has been shown to prevent type 1 diabetes (T1D) development, to prolong islet allograft survival and to inhibit β-cell apoptosis in vivo. It has also been reported that T1D patients have significantly lower plasma concentrations of AAT suggesting the potential role of AAT in the pathogenesis of T1D. We have investigated whether pl

The Swedish Spine Register: development, design and utility.

The Swedish Spine Register enables monitoring of surgical activities focusing on changes in trends over time, techniques utilized and outcome, when implemented in general clinical practice. Basic requirements for a prosperous register are unity within the profession, mainly patient-based documentation and a well functioning support system. This presentation focuses on the development and design of

Nonhormonal drug use and its relation to androgens in perimenopausal women: a population-based study of Swedish women. The Women's Health in the Lund Area Study.

OBJECTIVE:: To outline the prevalence of nonhormonal drug use in middle-aged women and to assess plausible associations between serum androgen levels and variables associated to health such as drug use and planned visits to healthcare units. METHODS:: This was a population-based study of women aged 50 to 59 years (n = 6,893). Women were divided into three groups according to their menopause status

Genetics of Type 2 Diabetes.

BACKGROUND: Type 2 diabetes (T2D) is a complex disorder that is affected by multiple genetic and environmental factors. Extensive efforts have been made to identify the disease-affecting genes to better understand the disease pathogenesis, find new targets for clinical therapy, and allow prediction of disease. CONTENT: Our knowledge about the genes involved in disease pathogenesis has increased su

Characterisation and utility of thiopurine methyltransferase and thiopurine metabolite measurements in autoimmune hepatitis.

BACKGROUND & AIMS: Corticosteroids alone or in conjunction with azathioprine (AZA) is the standard treatment in autoimmune hepatitis (AiH). Individual variations in thiopurine (TP) metabolism may affect both drug efficacy and toxicity. Our aim was to investigate the utility of thiopurine methyltransferase (TPMT) as well as thioguanine nucleotide (TGN) and methylthioinosine monophosphate (meTIM

How transfer of R&D to emerging markets nurtures global innovation performance

In the context of global R&D, we connect literature on knowledge management to a network-based theoretical framework helpful to analyse and explain the impact of globalisation of R&D on innovation performance. This framework is applied to two case companies, both global leaders within their respective industries, in order to analyse the extent to which their strategic globalisation of R&am

RIFM fragrance ingredient safety assessment, Linalyl isovalerate, CAS Registry Number 1118-27-0.

The use of this material under current use conditions is supported by the existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential, as well as, environmental safety. Reproductive toxicity was based on the Threshold of Toxicological Concern (TTC)

Soluble urokinase plasminogen activator receptor and incidence of venous thromboembolism.

Raised plasma levels of the soluble urokinase plasminogen activator receptor (suPAR) have been associated with increased incidence of cardiovascular diseases. Whether suPAR is associated with venous thromboembolism (VTE) is largely unknown. The purpose of the present study was to investigate the relationship between suPAR and incidence of VTE in a cohort study. suPAR was measured in 5,203 subjects
