Aim: Kynurenine metabolites are potential modulators of psychiatric disease. We aimed to develop a highly sensitive biochemical analysis of cerebrospinal fluid (CSF) tryptophan (TRP) metabolites, to investigate the stability of metabolites and to confirm our previous findings of aberrant CSF quinolinic acid (QUIN) and picolinic acid (PIC) in suicide attempters using this method. Methodology &
New rolling technique, i.e. asymmetric rolling combined with cross rolling is adopted to produce Ta sputtering targets in this study. Electron backscatter diffraction (EBSD) analysis suggests that (111) and (100) deformed grains distribute alternately along normal direction in cross rolling (CR) and asymmetric cross rolling (ACR) samples. Misorientation angle distribution indicates that severe ori
Introduction: Lobectomy is the standard curative treatment for non-small cell carcinoma (NSCLC) of the lung. Most studies on lobectomy have focused on short-term outcome and 30-day mortality. The aim of this study was to determine both short-term and long-term surgical outcome in all patients who underwent lobectomy for NSCLC in Iceland over a 24-year period. Material and methods: The study involv
Vertigo is one of the most common complaints in medicine. Despite its high prevalence, patients with vertigo often receive either inappropriate or inadequate treatment. The most important reasons for this deplorable situation are insufficient interdisciplinary cooperation, nonexistent standards in diagnostics and therapy, the relatively rare translations of basic science findings to clinical appli
In this study, a tank-connected food waste disposer system with the objective to optimise biogas production and nutrient recovery from food waste in Malmö was evaluated. The project investigated the source-separation ratio of food waste through waste composition analyses, determined the potential biogas production in ground food waste, analysed the organic matter content and the limiting component
Effective material parameters for diffusion and elastic deformation are calculatedfor porous materials using a continuum theory-based superposition procedure. The theory that is limited to two-dimensional cases, requires that the pores are sufficiently sparse. The methodleads to simple manual calculations that can be performed by, e.g. hospital staff at clinicaldiagnoses of bone deceases that invo
Design and properties are reported for a novel type of multi-channel isothermal microcalorimeter. It is equipped with 48 calorimetric units (channels) and is primarily intended for use as a monitor of the activity of living cells, tissues and small animals. Calorimetric vessels are positioned in a holder with the format of a 48-well microtiter plate. At most, 47 samples can be measured simultaneou
The issue of lag selection in ADF unit root testing is important, even asymptotically, for if the number of lags is not allowed to increase at a certain rate the test might not be correctly sized. However, size control is not the only concern. Indeed, simulations have repeatedly shown how increasing lag lengths tend to be associated with reductions in power, thus adding to the well-known low power
In this work, we have developed for the first time a method to make novel gold and platinum hybrid bimetallic nanostructures differing in shape and size. Au-Pt nanostructures were prepared by electrodeposition in two simple steps. The first step consists of the electrodeposition of nanocoral Au onto a gold substrate using hydrogen as a dynamic template in an ammonium chloride solution. After that,
Context. Determination of absolute parallaxes by means of a scanning astrometric satellite such as Hipparcos or Gaia relies on the short-term stability of the so-called basic angle between the two viewing directions. Uncalibrated variations of the basic angle may produce systematic errors in the computed parallaxes. Aims. We examine the coupling between a global parallax shift and specific variati
Background: The aim of this paper was to review the literature on vacuum-Assisted wound closure and mesh-mediated fascial traction (VAWCM) in open abdomen therapy. It was designed as systematic review of observational studies. Methods: A Pub Med, EMBASE and Cochrane search from 2007/01-2016/07 was performed combining the Medical Subject Headings "vacuum", "mesh-mediated fascial traction", "tempora
AIMS AND OBJECTIVES: To conduct a survey of the clinical nursing practice in European countries in accordance with the European Stroke Strategies (ESS) 2006, and to examine to what extent the ESS have been implemented in stroke care nursing in Europe.BACKGROUND: Stroke is a leading cause of death and disability globally. Optimal organisation of interdisciplinary stroke care is expected to ameliora
Screening for abdominal aortic aneurysm (AAA) has proven to reduce AAA-related mortality, but how the knowledge of having an untreated AAA affects health and daily life requires further clarification. The aim was to investigate the psychosocial consequences and sense of coherence (SOC) in 65-year-old men diagnosed with AAA and participating in a national screening program during a 6-month follow-u
Recently, decreased levels of apolipoprotein M (ApoM) were shown to be associated with higher risk of recurrent venous thromboembolism (VTE) in male patients. However, the role of ApoM in primary VTE is unknown. We aimed in our study to analyze the plasma levels of ApoM in patients with VTE in order to evaluate the diagnostic importance of ApoM in primary VTE. A total of 357 patients with suspecte
Fabless production, meaning manufacturing without owning fabrication facilities, has been suggested as a novelty by the semiconductor industry. However, Ikea, the global furniture company based in Sweden, has successfully been producing their furniture in a fabless fashion since 1955. This paper explores how Ikea manage and control its almost fabless production to reach the company’s targets for s
Routine monitoring of workplace exposure to polycyclic aromatic hydrocarbons (PAHs) is performed mainly via active sampling. However, active samplers have several drawbacks and, in some cases, may even be unusable. Polyurethane foam (PUF) as personal passive air samplers constitute good alternatives for PAH monitoring in occupational air (8 h). However, PUFs must be further tested to reliably yiel
In light of the speedy technological development in society, technical standards are becoming increasingly important. In the early days, the specific tasks delegated to standardization bodies under the New Approach did not attract much political interest. Today, however, politicians and different stakeholders realize that the tasks delegated to the standardization industry are highly important for
A series of comparative studies is suggested, focused on perceptions of outrigger canoes, and aimed at an increased understanding of the relationship between social relations, biodiversity, and sustainable development in Oceanic societies on small islands and in coastal areas undergoing rapid cultural change. After a critique of the recent notion that canoe-building in Polynesia developed as a res
