There are many ways to acquire and process diffusion MRI (dMRI) data for group studies, but it is unknown which maximizes the sensitivity to white matter (WM) pathology. Inspired by this question, we analyzed data acquired for diffusion tensor imaging (DTI) and diffusion kurtosis imaging (DKI) at 3T (3T-DTI and 3T-DKI) and DTI at 7T in patients with systemic lupus erythematosus (SLE) and healthy c

Climate change substantially affects plant phenology, resulting in earlier vegetation onset across temperate and boreal regions. Phenological shifts caused by warming may alter species interactions across trophic levels because of species-specific responses, and influence the reproductive success of dioecious species if the phenological sensitivity to warming (ST) differs between genders. We used

Water is a finite resource and should be given the attention it deserves to reduce its depletion through leakages in pipe systems. The authors implemented pressure management strategies linked to fixed and variable discharge (FAVAD), the burst and background estimate (BABE), and orifice principle methodologies to analyze a two-phased comparative method for applying optimal pressure management and

Background: Previous studies have reported Blood type O to confer a lower risk of SARS-CoV-2 infection, while secretor status and other blood groups have been suspected to have a similar effect as well. Study design and methods: To determine whether any other blood groups influence testing positive for SARS-CoV-2, COVID-19 severity, or prolonged COVID-19, we used a large cohort of 650,156 Danish b

Timely diagnosis of Alzheimer's disease (AD) is critical for appropriate treatment/patient management. Cerebrospinal fluid (CSF) biomarker analysis is often used to aid diagnosis. We assessed analytical performance of second-generation (Gen II) Elecsys® CSF immunoassays (Roche Diagnostics International Ltd), and adjusted existing cut-offs, to evaluate their potential utility in clinical routine. A

Background: In advanced Parkinson's disease (PD), dyskinesias and non-motor symptoms such as sleep dysfunction can significantly impair quality of life, and high-quality management is an unmet need. Objective: To analyze changes in dyskinesia and non-motor symptoms (including sleep) among studies with levodopa-carbidopa intestinal gel (LCIG) in patients with advanced PD. Methods: A comprehensive l

Background: The K3326X variant in BRCA2 (BRCA2∗c.9976A>T p.Lys3326∗rs11571833) has been found to be associated with small increased risks of breast cancer. However, it is not clear to what extent linkage disequilibrium with fully pathogenic mutations might account for this association. There is scant information about the effect of K3326X in other hormonerelated cancers. Methods: Using weighted lo

INTRODUCTION: Previous studies have shown an increased risk of obstetric complications in pregnancies after oocyte donation (OD). The present study includes all singletons born after OD during 10 years in Sweden.MATERIAL AND METHODS: A retrospective cohort study that included data from all Swedish in vitro fertilization (IVF) clinics between 2003 and 2012 was performed. Data were cross-linked with

Fuel cells, redox flow batteries and some water desalination technologies such as reverse osmosis and electrodialysis require efficient ion exchange membranes to perform in an optimum way. Thus, by enhancing the properties of these membranes there is a possibility to improve this type of applications and technologies. Depending on the specific application, anion or proton exchange membranes with g

Background: Lewy body Dementia (LBD) is a well-known neurocognitive disorder in the elderly. The hallmarks of LBD are Parkinsonism without tremor, recurrent and persistent visual hallucinations often with insight, fluctuating cognition and alertness, rapid eye movement (REM) sleep behavior disorder with vivid dreams and violent movements, but relatively preserved memory functions. Nevertheless, LB

Industrial biotechnology has been defined as the use and application of biotechnology for the sustainable processing and production of chemicals, materials and fuels. It makes use of biocatalysts such as microbial communities, whole-cell microorganisms or purified enzymes. Although biocatalysts are considered advantageous, since they operate under mild conditions regarding temperature and pH and e

This licentiate thesis in industrial design concerns the challenge and opportunity to meet the demographic changes and the future senior market. The aim is to explore how various user-centered design methods can be combined, modified and practiced to create conditions for the design of totally new or improved products. Design is understood as a process to develop solutions with the starting point

Popular Abstract in English The term perceptual alignment is used in various research fields to describe the extent to which individuals share the same perceptions about an object or idea. Perceptual alignment is important since strong corporate brands express associations and ideals that are attractive and appealing to stakeholders. This expression, when aligned, creates a sense of belonging to tThe term perceptual alignment is used in various research fields to describe the extent to which individuals share the same perceptions about an object or idea. Perceptual alignment is important from a corporate branding perspective because strong corporate brands express associations and sources of ideals that are attractive and appealing to the stakeholders related to the organisation. This expr

Background Elite athletes are role models for young sportspersons regarding social media use. Self-objectification, including self-sexualizing, contributes to body dissatisfaction and body shame, especially in young females. For efficient prevention of self-objectification, knowledge is needed about elite athletes’ self-presentation on social media.Objective To compare social media postings indica

Polycystic ovary syndrome (PCOS) is a medical condition with important consequences for women’s well-being and reproductive outcomes. Although the etiology of PCOS is not fully understood, there is increasing evidence of both genetic and environmental determinants, including development in early life. We studied a population of 977,637 singleton women born in in Sweden between 1973 and 1995, follo

Objective: There is an increased risk for cardiovascular disease (CVD) in patients with radiographic axial spondyloarthritis (r-axSpA). In this cross-sectional study, we aimed to, overall and stratified by sex, (i) compare ultrasound derived carotid intima media thickness (cIMT), between patients and controls, and (ii) investigate associations between cIMT, clinical disease activity and inflammati

The agricultural sector in northwestern Iran uses about 95 % of the region's available water resources and nearly 98 % of are aquifer water. Despite the regiońs previous richness in water resources, the supply is now quickly decreasing. The Ghorveh-Dehgolan sub-basin in northwestern Iran consists of three dams as well as three aquifers that supply water resources for agriculture, domestic uses, an

Serum electrophoresis (SPEP) is a method used to analyze the distribution of the most important proteins in the blood. The major clinical question is the presence of monoclonal fraction(s) of antibodies (M-protein/paraprotein), which is essential for the diagnosis and follow-up of hematological diseases, such as multiple myeloma. Recent studies have shown that machine learning can be used to asses
