A multicenter comparison of [18F]flortaucipir, [18F]RO948, and [18F]MK6240 tau PET tracers to detect a common target ROI for differential diagnosis

Purpose: This study aims to determine whether comparable target regions of interest (ROIs) and cut-offs can be used across [18F]flortaucipir, [18F]RO948, and [18F]MK6240 tau positron emission tomography (PET) tracers for differential diagnosis of Alzheimer’s disease (AD) dementia vs either cognitively unimpaired (CU) individuals or non-AD neurodegenerative diseases. Methods: A total of 1755 partic

Low-quality carbon and lack of nutrients result in a stronger fungal than bacterial home-field advantage during the decomposition of leaf litter

Decomposition of litter is a key biochemical process that regulates the rate and magnitude of CO2 fluxes from biosphere to atmosphere and determines soil nutrient availability. Although several studies have shown that plant litter decomposition accelerated in their native compared to a foreign environment, that is, a home-field advantage (HFA) for litter degradation, to date HFA has only been cons

Thromboembolism in Muscle-Invasive Bladder Cancer. A Population-based Nationwide Study

BACKGROUND: Routine VTE prophylaxis within 30 days of radical cystectomy (RC) for urinary bladder cancer (UBC) is used to protect from venous thromboembolism (VTE). However, randomized studies and nationwide population-based studies are lacking. OBJECTIVE: To study VTE and risk factors for VTE in muscle-invasive UBC in a nationwide population-based series, with a focus on the association with RC w

The genetic base for peanut height-related traits revealed by a meta-analysis

Peanut (Arachis hypogaea L.) is an important oilseed crop worldwide, and peanut height has been shown to be closely related to yield, therefore a better understanding of the genetic base of plant height-related traits may allow us to have better control of crop yield. Plant height-related traits are quantitative traits that are genetically controlled by many genes, and distinct quantitive trait lo

Ease or excitement? Exploring how concept stores contribute to a retail portfolio

Purpose: The study aims to explore how concept stores (theoretically) differ from other experience-based retail formats, and hence, how they (practically) contribute to a diversified retail store portfolio. Design/methodology/approach: Case study based on semi-structured, qualitative interviews with seven IKEA retail managers, three industry experts and 26 customers of IKEA concept stores in Londo

The lichen genus Villophora (Teloschistaceae, Ascomycota)

The Southern Hemisphere lichen genus Villophora in subfamily Teloschistoideae is analyzed based on DNA sequence data. Six species are described, five of which are new to science: V. darwiniana and V. wallaceana grow on lignum and bark in southern Patagonia and Tierra del Fuego; V. onas and V. patagonica are lichenicolous or saxicolous on rocks in southern Patagonia; V. rimicola is saxicolous in An

Visual Symptoms and Risk Assessment Using Visual Ergonomics Risk Assessment Method (VERAM)

A visual environment impaired by e.g. glare can cause eyestrain, visual symptoms and musculoskeletal strain. A Visual Ergonomics Risk Assessment Method (VERAM) consisting of both a subjective questionnaire and an objective risk assessment, have been used at 217 workplaces, mainly computer work. VERAM can be used to examine and prevent deficiencies and increase wellbeing as well as detecting risks

Psychometric properties of the Norwegian translation of the Tinnitus Handicap Inventory (THI-NOR)

Objective: To assess the psychometric properties of a Norwegian translation of the Tinnitus Handicap Inventory (THI-NOR). Design: A survey was sent by post to patients referred with tinnitus as their main complaint to an audiology department. Patients completed a Norwegian version of the Tinnitus Handicap Inventory (THI-NOR), a Norwegian translation of two revised subscales of the Abbreviated prof

‘Too many mice make no lining for their nest’ : Reasons and effects of parallel governmental structures for disaster risk reduction and climate change adaptation in Southern Africa

Many African countries face escalating challenges of increasing disaster risk and anticipated impacts of climate change. Although disaster risk reduction (DRR) and climate change adaptation (CCA) are tightly linked and comprising virtually identical practices in vulnerable countries in Southern Africa, research has identified parallel governance structures across the region. This study applied com

Climate change and energy performance of European residential building stocks : A comprehensive impact assessment using climate big data from the coordinated regional climate downscaling experiment

In recent years, climate change and the corresponding expected extreme weather conditions have been widely recognized as potential problems. The building industry is taking various actions to achieve sustainable development, implement energy conservation strategies, and provide climate change mitigation. In addition to mitigation, it is crucial to adapt to climate change, and to investigate the po

General Trends in Core-Shell Preferences for Bimetallic Nanoparticles

Surface segregation phenomena dictate core-shell preference of bimetallic nanoparticles and thus play a crucial role in the nanoparticle synthesis and applications. Although it is generally agreed that surface segregation depends on the constituent materials' physical properties, a comprehensive picture of the phenomena on the nanoscale is not yet complete. Here we use a combination of molecular d

Dags att i grunden förändra vår relation till havet

Debatt: Med djup oro ser vi dramatiska förändringar med konsekvenser för både människor och djur. Nu behöver vi alla på ett fundamentalt sätt förändra vårt förhållande till havet. Det skriver 78 forskare, som i dag vill uppmärksamma Världshavsdagen och FN:s årtionde för havsforskning för hållbar utveckling.
