A recent genome-wide association study revealed a variant (rs2431697) in an intergenic region, between the pituitary tumor-transforming 1 (PTTG1) and microRNA (miR-146a) genes, associated with systemic lupus erythematosus (SLE) susceptibility. Here, we analyzed with a case-control design this variant and other candidate polymorphisms in this region together with expression analysis in order to cla

In the paper we present a research model for evaluating determinants of ERP value in small and medium-size enterprises (SMEs). The model is grounded in the diffusion of innovation (DOI) model and resource-based view of the firm (RBV) theory. The research model links six DOI determinants to explain ‘ERP use’ linked with two additional determinants to explain ‘ERP value’, on which nine hypotheses ar

During the process of biomass gasification tars are formed which exit the gasifier in vapor phase. Tar condensation creates problems like fouling and plugging of after-treatment, conversion and end-use equipment. Gasification tars consist mainly of Polycyclic Aromatic Hydrocarbons (PAHs). Former research has shown the possibilities and difficulties of tar conversion by partial combustion. Basic st

Streptococcus pneumoniae is a leading cause of invasive bacterial infections, with nasal colonization an important first step for disease. While cigarette smoking is a strong risk factor for invasive pneumococcal disease, underlying mechanisms remain unknown. This is partly due to a lack of clinically relevant animal models investigating nasal pneumococcal colonization in the context of cigarette

Pseudomyogenic haemangioendothelioma (PHE) is an intermediate malignant vascular soft tissue tumour primarily affecting children and young adults. The molecular basis of this neoplasm is unknown. We here used chromosome banding analysis, fluorescence in situ hybridization (FISH), mRNA sequencing, RT-PCR and quantitative real-time PCR on a series of morphologically well-characterized PHEs to show t

Buildings are getting taller due to increased urbanisation and densification of cities. More advanced construction methods and the desire to construct impressive buildings is also supporting the trend. Due to their inherent slenderness resulting in low eigenfrequencies, these buildings are susceptible to wind-induced vibrations which can be highly disturbing for occupants. Already barely perceivab

We analyze the convergence rate of the Dirichlet-Neumann iteration for the fully discretized one dimensional unsteady transmission problem. Specifically, we consider the coupling of two linear heat equations on two identical non overlapping intervals. The Laplacian is discretized using finite differences on one interval and finite elements on the other and the implicit Euler method is used for the

The patient is the centre of a web of relationships, and the impact of his/her disease on family members and caregivers must be taken into account. The aim of this study was to identify the specific instruments that measure the impact of a dermatological disease on the quality of life (QoL) of family members, by performing a systematic search of the literature. Fifteen papers were identified, desc

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

Background: The main purpose for measuring urinary free sialic acid (FSA) is to diagnose sialic acid (SA) storage diseases. Elevated amounts of conjugated sialic acid (CSA) are observed in several diseases indicating the need to quantify CSA as well. A LC-MS/MS method for quantification of FSA and total sialic acid (TSA) in urine is developed and validated. Methods: FSA is analyzed directly after

INTRODUCTION: Endovascular thrombectomy (EVT) is a significant improvement in the care of acute ischemic stroke (AIS) patients, but only a small portion of patients receive treatment. Our aim was to analyze EVT implementation in Sweden according to a set of key performance indicators (KPIs) for procedural and implementational effectiveness. METHODS: A nationwide prospective registry-based observ

Purpose: The study aims to advance the understanding of collaborative consumption through the research on the engagement rules, conventions, and norms that govern the practice. The study postulates that it is through the possession of the right competences and meaning that permit insiders to successfully apply the rules of collaborative consumption while deterring outsiders from making an initial

Ett patent är en immateriell rättighet som medför en ensamrätt för patenthavaren att dra affärsmässig nytta av en viss uppfinning under en begränsad tidsperiod. Den som kränker patenthavarens ensamrätt gör sig skyldig till patentintrång. Vid patentintrång tillhandahåller den svenska patentlagen (1967:837) ett antal olika sanktionsmöjligheter. De primära civilrättsliga sanktionsformerna utgörs av pA patent is a kind of intellectual property right that grants the patent holder an exclusive right to profit from a certain invention for a limited time period. Anyone who violates the patent holder's exclusive right is guilty of patent infringement. In cases of patent infringement the Swedish Patent Act (patentlag 1967: 837) provides a number of different sanction options. The primary civil s

De flesta av oss associerar nog kemikalier med något negativt, men sanningen är att kemikalier utgör en förutsättning för mycket av den välfärd som vi ser idag. Tvärtemot vad man kan tro, så är det inte bara i produkter som plast, färg, lösningsmedel, med mera som dessa förekommer, utan även i produkter som räddar liv, till exempel i utrustning inom sjukvården och för vattenrening. Därför är de meThe production and use of chemicals has grown exponentially over the past 50 years. Although the knowledge of hazards and risks associated with chemicals towards humans and the environment has increased, we know frightenedly little about how dangerous these might become when part of finished products. Companies now need to be more concerned about which chemicals exist in their products. For the co

The thesis circles around Social Media, B2B Brand Building and Business Performance Measurements. In the intersection between these a knowledge gap was identified. The following research questions were formed: How should companies go about when implementing Social Media? How should the performance of Social Media engagement be measured? The urgency for answering these questions was identified. Th

Tissue clearing allows 3D-imaging of large biomedical samples, but can be affected by blur effects limiting individual cells detection. Using a structured illumination light sheet we solve this issue, obtaining high-contrast images in turbid samples.

Food additives such as emulsifiers are used in increasing quantities in the food industry. The aim of this study was to compare three different emulsifiers (polysorbate 80 (P80), carboxymethyl cellulose (CMC), and β-lactoglobulin (β-lac) with regards to their effect on the stimulation of immune cells and intestinal permeability. The immune stimulatory effects were studied in the myeloid cell line

Pneumonia is a global cause of mortality, and this provides a strong incentive to improve the mechanistic understanding of innate immune responses in the lungs. Here, we characterized the involvement of the cytokine interleukin (IL)-26 in bacterial lung infection. We observed markedly increased concentrations of IL-26 in lower airway samples from patients with bacterial pneumonia and these correla

The major inhibitor of the cysteine class of proteinases found in human body fluids, such as spinal fluid, milk, and seminal plasma, is cystatin C. In this study we show that human bronchoalveolar fluid also contains cystatin C and examine cystatin C expression by alveolar macrophages in vitro. Immunoprecipitation of extracts of metabolically labeled cells and immunoblotting of cellular extracts a
