Background: Neuropathological studies have linked tau aggregates to neuronal loss. To describe the spatial distribution of neurofibrillary tangle pathology in post-mortem tissue, Braak staging has been used. The aim of this study was to examine in vivo associations between tau pathology, quantified with [18F]flortaucipir PET in regions corresponding to Braak stages, and atrophy across the Alzheime

Background: Infarct evolution rate and response to acute reperfusion therapy may differ between patients, which is important to consider for accurate management and treatment of patients with ST-elevation myocardial infarction (STEMI). The aim of this study was therefore to investigate the association of infarct size and myocardial salvage with gender, smoking status, presence of diabetes or histo

Background: In 2006 and 2007 we performed double lung transplantation with marginal donor lungs assessed and reconditioned by Ex Vivo Lung Perfusion (EVLP), using a technique developed by Professor Stig Steen. Here we present a 10-year follow-up comparing the outcomes of lung transplantations performed at our clinic using EVLP lungs vs. conventional lungs. Method: Between 2006 and 2007, 21 patient

Objectives. To examine faecal calprotectin (F-calprotectin) levels and presence of anti-Saccharomyces cerevisiae antibodies (ASCA) and their associations with disease subtype and current status in axial SpA (axSpA). Methods. F-calprotectin and ASCA in serum were compared between consecutive patients with a clinical axSpA diagnosis, classified as non-radiographic axSpA (nr-axSpA; n = 40) or AS (n =

Behavioral adaptations play an important role in predator–prey interactions as they reduce predation risk. Prey organisms have therefore evolved a tremendous variability in behavioral adaptations. In case of small crustaceans of the genus Daphnia, which are common and important herbivores transferring energy from primary producers to higher trophic levels, such as predatory fish, and insects, alte

The main objective for this article is to explore how users of psychoactive drugs experience time and the role psychoactive drugs play in the management and construction of time. The data in this study consists of different kinds of written documents such as anecdotal accounts and scientific articles and reports which was collected using a purposeful sampling technique.

AIMS: This nationwide study aimed to analyse the first 2 years of routine clinical use of cangrelor in all Swedish patients undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS: This observational Swedish Coronary Angiography and Angioplasty Registry (SCAAR) study identified 915 cangrelor-treated patients. As 899 were ST-segment elevation myocardial infarction (STEMI)-patients

We investigate the relation between large negative house price co-movements in the cross-section of US cities and the national business cycle. The occurrences of large negative house price co-movements across cities cluster over time and these clusters are closely linked to NBER recession dates. A simple co-movement measure that aggregates large negative city-level house price returns reliably pre

Electron density determination based on structure factors obtained through powder X-ray diffraction has so far been limited to high-symmetry inorganic solids. This limit is challenged by determining high-quality structure factors for crystalline urea using a bespoke vacuum diffractometer with imaging plates. This allows the collection of data of sufficient quality to model the electron density of

Advanced preservation injury (PI) after intestinal transplantation has deleterious short-and long-term effects and constitutes a major research topic. Logistics and costs favor rodent studies, whereas clinical translation mandates studies in larger animals or using human material. Despite diverging reports, no direct comparison between the development of intestinal PI in rats, pigs, and humans is

Production studies show that anaphoric reference is bimodal. Speakers can introduce a referent in speech by also using a localizing gesture, assigning a specific locus in space to it. Referring back to that referent, speakers then often accompany a spoken anaphor with a localizing anaphoric gesture (i.e., indicating the same locus). Speakers thus create visual anaphoricity in parallel to the anaph

Quantum dots (QDs) can serve as near perfect energy filters and are therefore of significant interest for the study of thermoelectric energy conversion close to thermodynamic efficiency limits. Indeed, recent experiments in [Nat. Nano. 13, 920 (2018)1748-338710.1038/s41565-018-0200-5] realized a QD heat engine with performance near these limits and in excellent agreement with theoretical predictio

Background: Sentinel lymph node biopsy (SLNB) is standard staging procedure for nodal status in breast cancer, but lacks therapeutic benefit for patients with benign sentinel nodes. For patients with positive sentinel nodes, individualized surgical strategies are applied depending on the extent of nodal involvement. Preoperative prediction of nodal status is thus important for individualizing axil

Objective To investigate the contemporary presentation of pituitary metastases. Patients Thirty-eight patients diagnosed with pituitary metastases from 1996 to 2018 in Sweden. Methods Pituitary metastases were confirmed by histopathology (n = 27) or considered highly likely according to radiological findings, including rapid tumor progression (n = 11). Medical records were reviewed and sellar imag
