The National Prevalence of Clinically Diagnosed Psoriatic Arthritis in Sweden in 2017

Objective. Psoriatic arthritis (PsA) prevalence estimates vary across studies; studies based on national data are few. We aimed to estimate the prevalence of clinically diagnosed PsA in Sweden in 2017, overall and stratified by sex, age, education, and geography, and to quantify disease-modifying antirheumatic drug (DMARD) use among those in contact with specialized rheumatology care between 2015

Complexes of Charged-Neutral Block Copolymers and Surfactants : Process-Dependent Features and Long-Term Stability of Their Aqueous Dispersions

Aqueous dispersions of charged-neutral block copolymers (poly(acrylamide)-b-poly(acrylate)) complexed with an oppositely charged surfactant (dodecyltrimethylammonium) have been prepared by different approaches: the simple mixing of two solutions (MS approach) containing the block copolymer and surfactant, with their respective simple counterions, and dispersion of a freeze-dried complex salt prepa

Patients with no preoperative back pain have the best outcome after lumbar disc herniation surgery

Purpose: Most patients with lumbar disc herniations requiring surgery have concomitant back pain. The purpose of the current study was to evaluate the outcome of surgery for lumbar disc herniations in patients with no preoperative back pain (NBP) compared to those reporting low back pain (LBP). Methods: 15,418 patients surgically treated due to LDH with primary discectomy from 1998 until 2020 were

The unhappy chaperone

Chaperones protect other proteins against misfolding and aggregation, a key requirement for maintaining biological function. Experimental observations of changes in solubility of amyloid proteins in the presence of certain chaperones are discussed here in terms of thermodynamic driving forces. We outline how chaperones can enhance amyloid solubility through the formation of heteromolecular aggrega

Block Copolymer Nanolithography for Sub-50 nm Structure Applications

När de kritiska mönsterdimensionerna för högteknologiska enheter fortsätter krympa och mönstertätheten fortsätter öka, behöver även litografin att gå i samma riktning. En lovande teknologi är sampolymerlitografi, som har en upplösning under 10 nm, en mönsterperiodicitet omkring 7-200 nm, och lätt kan skalas upp till större ytor till en låg kostnad. Användandet av sampolymerer där de ingående blockAs high technology device patterns are continuing to move towards decreasing critical dimensions and increasing pattern density, there is a need for lithography to move in the same direction. Block copolymer (BCP) lithography is a promising technique, which has single digit nanometer resolution, has a pattern periodicity of about 7-200 nm, and easily scales up to large area at a low cost. The use

The advantage of laser-capture microdissection over whole tissue analysis in proteomic profiling studies

Laser-capture microdissection (LCM) offers a reliable cell population enrichment tool and has been successfully coupled to MS analysis. Despite this, most proteomic studies employ whole tissue lysate (WTL) analysis in the discovery of disease biomarkers and in profiling analyses. Furthermore, the influence of tissue heterogeneity in WTL analysis, nor its impact in biomarker discovery studies have

Combined Magnetomotive ultrasound, PET/CT, and MR imaging of (68)Ga-labelled superparamagnetic iron oxide nanoparticles in rat sentinel lymph nodes in vivo

Current methods for intra-surgical guidance to localize metastases at cancer surgery are based on radioactive tracers that cause logistical challenges. We propose the use of a novel ultrasound-based method, magnetomotive ultrasound (MMUS) imaging that employ a nanoparticle-based contrast agent that also may be used for pre-operative PET/MRI imaging. Since MMUS is radiation free, this eliminates th

Using a multi-feature paradigm to measure mismatch responses to minimal sound contrasts in children with cochlear implants and hearing aids

Our aim was to explore whether a multi-feature paradigm (Optimum-1) for eliciting mismatch negativity (MMN) would objectively capture difficulties in perceiving small sound contrasts in children with hearing impairment (HI) listening through their hearing aids (HAs) and/or cochlear implants (CIs). Children aged 5–7 years with HAs, CIs and children with normal hearing (NH) were tested in a free-fie

Patchy field sampling biases understanding of climate change impacts across the Arctic

Effective societal responses to rapid climate change in the Arctic rely on an accurate representation of region-specific ecosystem properties and processes. However, this is limited by the scarcity and patchy distribution of field measurements. Here, we use a comprehensive, geo-referenced database of primary field measurements in 1,840 published studies across the Arctic to identify statistically

Experimental and kinetic modelling investigation on NO, CO and NH3 emissions from NH3/CH4/air premixed flames

Ammonia (NH3) is regarded as one of the most viable alternatives to produce carbon-free energy. However, its low flammability and high NOx emissions associated with its combustion inhibit the implementation of pure NH3 as a fuel. Dual-fuel approaches with NH3 and more reactive fuels have been proposed; however, information on pollutant emissions is still scarce. The present work focuses on quantif

Nerve-dependent and -independent tenascin expression in the developing chick limb bud

The extracellular matrix protein, tenascin, appears in a restricted pattern during organ morphogenesis. Tenascin accumulates along developing peripheral nerves as they leave the spinal cord and enter the limb mesenchyme (Wehrle and Chiquet, Development 110, 401-415, 1990). Here we found that most but not all tenascin deposited along growing nerves is of glial origin. By in situ hybridization with

Semen quality in relation to xenohormone and dioxin-like serum activity among inuits and three european populations

BACKGROUND: Semen quality in humans may be influenced by exposure to endocrine-disrupting compounds. OBJECTIVES: We analyzed associations between semen characteristics and serum xenoestrogen receptor (XER), xenoandrogen receptor (XAR), and aryl hydrocarbon receptor (AhR) transactivity. XER and XAR activity were measured in serum samples cleared for endogenous steroid hormones and AhR activity in r

Triglyceride interesterification by lipases. 1. Cocoa butter equivalents from a fraction of palm oil

Twelve commercially available triacylglycerol lipase preparations were screened for their suitability as catalysts in the interesterification of palm oil mid fraction and ethyl stearate to form a cocoa butter equivalent. Five fungal lipase preparations were found to be suitable. The hydrolytic activity of the commercial lipase preparations was tested with sunflower seed oil and was independent of

CRP in Outpatients with Inflammatory Bowel Disease Is Linked to the Blood Microbiota

The circulation is a closed system that has been assumed to be free from bacteria, but evidence for the existence of a low-density blood microbiota is accumulating. The present study aimed to map the blood microbiota of outpatients with Crohn’s disease (CD) or with ulcerative colitis (UC) by 16S metagenomics. A diverse microbiota was observed in the blood samples. Regardless of the type of disease

Railway maintenance windows : Discrepancies between planning and practice in Sweden

Efficient and timely maintenance is essential for the robust operation of infrastructure across all types of transport. In the railway sector, track maintenance presents unique challenges. Specifically, some maintenance tasks require track closures, which can disrupt train schedules. Coordinating these closures with regular train operations makes the scheduling process complicated. To ensure suffi

Volcanic impact on the climate - The stratospheric aerosol load in the period 2006-2015

We present a study on the stratospheric aerosol load during 2006-2015, discuss the influence from volcanism and other sources, and reconstruct an aerosol optical depth (AOD) data set in a resolution of 1° latitudinally and 8 days timewise. The purpose is to include the "entire" stratosphere, from the tropopause to the almost particle-free altitudes of the midstratosphere. A dynamic tropopause of 1
