Popular Abstract in Swedish Miljontals fåglar lämnar Sverige varje höst för att övervintra på sydligare breddgrader och återvänder nästkommande vår för att föda upp sina ungar på de enorma mängder insekter som finns här tack vare det tempererade klimatet. Småfåglar genomför sin flytt etappvis genom att flyga ett antal dagar eller nätter i sträck, beroende på om fågeln är en dag- eller nattsträckarSongbird migrants use stopovers between flight bouts to rest and refuel for the upcoming flights. Behaviours affecting where, when and how long to stay at stopover sites will affect how successful the overall migration will be, which has significant consequences for the overall fitness and mortality of the birds. The main purpose of this work was to investigate stopover behaviours in free-flying m

Objectives In an acute heart failure (AHF) setting, proenkephalin A 119-159 (penKid) has emerged as a promising prognostic marker for predicting worsening renal function (WRF), while bioactive adrenomedullin (bio-ADM) has been proposed as a potential marker for congestion. We examined the diagnostic value of bio-ADM in congestion and penKid in WRF and investigated the prognostic value of bio-ADM a

In the last decade, organoid technology has filled the gap generated by the poor accessibility and unique features of the human brain. Organoids present several advantages in comparison with two-dimensional culturing, since they recapitulate cytoarchitecture in space and functionality of the tissue. Therefore, they mimic the unique features of human brain better than animal models. Although signif

Background: Since long travel times to reach health facilities are associated with worse outcomes, geographic accessibility is one of the six core global surgery indicators; this corresponds to the second of the “Three Delays Framework,” namely “delay in reaching a health facility.” Most attempts to estimate this indicator have been based on geographical information systems (GIS) algorithms. The a

Objective To estimate, using numerical calculations, the depth of tissue damage in the uterus following balloon thermal endometrial destruction. Design A parameter, therapeutic depth, was defined. This was the maximum depth into the uterine myometrium, from the uterine cavity, at which a predefined temperature was reached after a certain time and with a constant intracavitary temperature. Setting

The central challenge tackled in this thesis is the development of an optical imaging approach capable of multidimensional image capture of dynamic samples. Many conventional optical imaging approaches, which can obtain dimensional information such as spectral, polarisation, or volumetric, to name a few, about samples either employ sequential image capture or parallelised detector arrangements. Du

Background: Limited scientific evidence for prevention and treatment of diabetic foot ulcers in elderly with comorbidities. Aim: To explore patient-related factors and outcomes in patients ≥75 years with diabetes and a foot ulcer. Method: Sub-analysis of consecutively presenting patients ≥75 years (N = 1008) from a previous study on 2,480 patients with diabetic foot ulcer treated in a multidiscipl

Novel approach for membrane modification to improve separation performance and antifouling stability was proposed. It involves using of 0.1–0.3 wt.% aqueous solutions of Praestol 859 (cationic polyelectrolyte based on copolymer of acrylamide and 2-acryloxyethyltrimethylammonium chloride) as coagulants upon membrane preparation via non-solvent induced phase separation. It was shown that the additio

Semiconductor nanowires in wrapped, gate-all-around transistor geometry are highly favorable for future electronics. The advanced nanodevice processing results in strain due to the deposited dielectric and metal layers surrounding the nanowires, significantly affecting their performance. Therefore, non-destructive nanoscale characterization of complete devices is of utmost importance due to the sm

Field-based thermal infrared cameras provide surface temperature information at very high spatial and temporal resolution and could complement existing phenological camera and spectral sensor networks. Since temperature is one of the main drivers of ecosystem respiration (ER), field-based thermal cameras offer a new opportunity to model and upscale ER in unprecedented detail. We present such an ap

The cholinergic hypothesis of geriatric memory dysfunction suggests that the learning and memory deficits representing the cardinal symptoms of dementia in the aged and in patients suffering from Alzheimer's disease may be attributable to a decline in the function of the cholinergic projection systems of the basal forebrain. Although many studies have addressed the issue of a causal relationship b

The Drosophila gene ten-m is the first pair-rule gene not encoding a transcription factor, but an extracellular protein. We have characterized a highly conserved chicken homologue that we call teneurin-1. The C-terminal part harbors 26 repetitive sequence motifs termed YD-repeats. The YD-repeats are most similar to the core of the rhs elements of Escherichia coli. Related repeats in toxin A of Clo

Titanium dioxide (TiO2) is a unique material for biosensing applications due to its capability of hosting enzymes. For the first time, we show that TiO2 can accumulate reactive oxygen species (ROS) under daylight irradiation and can support the catalytic cycle of horseradish peroxidase (HRP) without the need of H2O2 to be present in the solution. Phenolic compounds, such as hydroquinone (HQ) and 4

Objective:The objective of this review was to assess associations between Individual Placement and Support (IPS), employment, and personal and clinical recovery among persons with severe mental illness at 18-month follow-up.Methods:A systematic literature search identified randomized controlled trials (RCTs) comparing IPS with services as usual. Outcomes were self-esteem, empowerment, quality of l

Introduction: The purpose of this study was to investigate neurological disorder as a risk factor for dislocation following arthroplasty for acute hip fractures. We also analysed medical and surgical adverse events (AE), readmission, reoperation, revision, and mortality as secondary outcomes. Methods: A longitudinal cohort study using prospectively collected and aggregated data from the Swedish Hi

The first great ruler to encourage the adoption of Western culture and technology throughout Siam was King Narai, who also had a passion for astronomy. He showed this by encouraging French and other Jesuit missionaries, some with astronomical interests and training, to settle in Siam from the early 1660s. One of these was Father Antoine Thomas, and he was the first European known to have carried o
