Optimized Standard Operating Procedures for the Analysis of Cerebrospinal Fluid Aβ42 and the Ratios of Aβ Isoforms Using Low Protein Binding Tubes

Background: Reduced cerebrospinal fluid (CSF) concentration of amyloid-β1-42 (Aβ1-42) reflects the presence of amyloidopathy in brains of subjects with Alzheimer's disease (AD). Objective: To qualify the use of Aβ1-42/Aβ1-40 for improvement of standard operating procedures (SOP) for measurement of CSF Aβ with a focus on CSF collection, storage, and analysis. Methods: Euroimmun ELISAs for CSF Aβ is

Albumin Turnover in Peritoneal and Hemodialysis

The turnover of albumin is increased in both peritoneal dialysis (PD) and hemodialysis (HD) due to increased external losses, normally leading to compensatory increases in the hepatic albumin synthesis. The normal rate of albumin synthesis is on the order of 12 g/day corresponding to an equally large albumin fractional catabolic rate of ~4% daily. Most albumin catabolism is assumed to occur in the

Physiological variation in left atrial transverse orientation does not influence orthogonal P-wave morphology

Background: It has previously been demonstrated that orthogonal P-wave morphology in healthy athletes does not depend on atrial size, but the possible impact of left atrial orientation on P-wave morphology remains unknown. In this study, we investigated if left atrial transverse orientation affects P-wave morphology in different populations. Methods: Forty-seven patients with atrial fibrillation,

The european hematology association roadmap for european hematology research : A consensus document

The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will hel

Burnout among Swedish school teachers - a cross-sectional analysis

Background: Teachers are at high risk of stress-related disorders. This study aimed to examine the occurrence of burnout in a sample of Swedish school-teachers, to test a combined measure of three burnout dimensions on the individual level, to characterize associations between burnout and factors encountered during work and leisure time, and to explore any differences between the genders. Methods:

Gender in relation to work motivation, satisfaction and use of day center services among people with psychiatric disabilities

Background: Day centres can prepare for open-market employment, and attendees’ work motivation is key in this. Aims: Adopting a gender perspective, this study investigated (1) motivation for day centre attendance, satisfaction with the day centre services, number of hours spent there, and number and type of occupations performed; and (2) whether those factors were related with motivation for open-

Warfarin treatment and risk of stroke among primary care patients with atrial fibrillation

Objective. Our aim was to study the risk of a first ischaemic stroke (IS) in patients with atrial fibrillation (AF) treated in primary healthcare. Design. The study population included all adults (n = 11,517), 45 years and older diagnosed with AF, from 75 primary care centres in Sweden between 2001 and 2007. IS was defined as a hospital care event of stroke between 2001 and 2010. Association betwe

Opting to wear prismatic spectacles was associated with reduced neck pain in dental personnel : A longitudinal cohort study

Background: The aim of this study was to investigate effects on perceived exertion, work ability self-reported neck pain and clinically diagnosed conditions in the neck, of an intervention with prismatic spectacles among dental personnel. Methods: In this cohort study a baseline questionnaire including questions about frequency of neck pain, perceived exertion during work and background informatio

"All is well" : Professionals' documentation of social determinants of health in Swedish Child Health Services health records concerning maltreated children - a mixed method approach

Background: Knowledge about social determinants of health has influenced global health strategies, including early childhood interventions. Some psychosocial circumstances - such as poverty, parental mental health problems, abuse and partner violence - increase the risk of child maltreatment and neglect. Healthcare professionals' awareness of psychosocial issues is of special interest, since they

Multiregion whole-exome sequencing uncovers the genetic evolution and mutational heterogeneity of early-stage metastatic melanoma

Cancer genome sequencing has shed light on the underlying genetic aberrations that drive tumorigenesis. However, current sequencing-based strategies, which focus on a single tumor biopsy, fail to take into account intratumoral heterogeneity. To address this challenge and elucidate the evolutionary history of melanoma, we performed whole-exome and transcriptome sequencing of 41 multiple melanoma bi

Metastasis stimulation by hypoxia and acidosis-induced extracellular lipid uptake is mediated by proteoglycan-dependent endocytosis

Hypoxia and acidosis are inherent stress factors of the tumor microenvironment and have been linked to increased tumor aggressiveness and treatment resistance. Molecules involved in the adaptive mechanisms that drive stress-induced disease progression constitute interesting candidates of therapeutic intervention. Here, we provide evidence of a novel role of heparan sulfate proteoglycans (HSPG) in

Monarchies as corporate brands

This paper explores monarchies through a corporate branding lens. It is based on extensive field interviewing of individuals with knowledge and experience in what we (not they) term “managing the Crown as a brand,” including senior members of the Swedish Royal Court and the Swedish Royal Family. It also draws from literature regarding monarchies across a range of disciplines beyond management; we

City-Scale Localization for Cameras with Known Vertical Direction

We consider the problem of localizing a novel image in a large 3D model, given that the gravitational vector is known. In principle, this is just an instance of camera pose estimation, but the scale of the problem introduces some interesting challenges. Most importantly, it makes the correspondence problem very difficult so there will often be a significant number of outliers to handle. To tackle

Optimization schemes for efficient multiple exciton generation and extraction in colloidal quantum dots

Multiple exciton generation (MEG) is a process in which more than one electron hole pair is generated per absorbed photon. It allows us to increase the efficiency of solar energy harvesting. Experimental studies have shown the multiple exciton generation yield of 1.2 in isolated colloidal quantum dots. However real photoelectric devices require the extraction of electron hole pairs to electric con

Landsbygdsnytta som motiv för stöd till landsbygden

Andelen av befolkningen som bor på landsbygen minskar kontinuerligt samtidigt som det finns en stark politiks önskan att bevara en livskraftig landsbygd. I rapporten identifierar vi samhällsnyttor av att människor lever, bor och verkar på landsbygden med utgångspunkt i begreppet landsbygdsnytta. Vilka av dessa nyttor kan motivera en specifik landsbygdspolitik för att dessa nyttor ska bevaras?

On parametric effects of wettability, surface roughness and porosity on nucleate pool boiling heat transfer

Phase-change heat transfer enhancement is of critical importance to meet high cooling demands. Recently, surface engineering (surface modification) is emerged as a promising heat transfer enhancement method, especially with the development of nanotechnology. Surface parameters such as wettability, surface roughness and porosity are modified by surface engineering. This work aims to discuss the parPhase-change heat transfer enhancement is of critical importance to meet high cooling demands.

Effects of a healthy Nordic diet on gene expression changes in peripheral blood mononuclear cells in response to an oral glucose tolerance test in subjects with metabolic syndrome : A SYSDIET sub-study

Background: Diet has a great impact on the risk of developing features of metabolic syndrome (MetS), type 2 diabetes mellitus (T2DM), and cardiovascular diseases (CVD). We evaluated whether a long-term healthy Nordic diet (ND) can modify the expression of inflammation and lipid metabolism-related genes in peripheral blood mononuclear cells (PBMCs) during a 2-h oral glucose tolerance test (OGTT) in
