Selenium (Se), an important micronutrient with several biological effects, exhibits improved stability, biocompatibility, and safety through nanoparticle (NP) formulation. We present here a novel approach for producing smaller and structurally stable biogenic selenium nanoparticles (SeNPs) with bioactive coating. Poly(allylamine hydrochloride)-coated SeNPs were synthesized biogenically using Tra
Granskning av språkliga och innehållsliga val och strategier i primärt två översättningar av Axel Wallengrens "fakirtexter" till tyska respektive danska med särskilt fokus på Wallengrens s k alfabetsverser.
This paper presents hitherto unknown finds of baleen whale from Iron Age Scania. Through the peptide-based technique Zooarchaeology by Mass Spectrometry (ZooMS), we provide the first identifications of remains of humpback whale (Megaptera novaeaenglia) and fin whale (Balaenoptera physalus) in Scania and we present the first identification of North Atlantic right whale (Eubalaena glacialis) or bowh
This thesis consists of four self-contained empirical studies on how economic shocks and structural changes shape individual behavior and local outcomes.Paper I examines how military base closures affect young adults’ education and labor market outcomes. The results show that men respond by increasing tertiary education, while women experience improved short-term labor market outcomes, suggesting
As media consumption becomes increasingly individualized, people’s desire for shared cultural experiences remains. Reaction media provides one way to fulfil that need, fostering transnational community (Swan 2018) and a sense of co-presence and immediacy. In their most basic form, reaction media show people filming themselves or being filmed while reacting – viewing, eating, playing, trying out or
Sjunkande tittarsiffror och avtagande samtidsrelevans har fått många att undra om inte dagarna är räknade för tv:s late-night talkshows. Men nu verkar den förmodade nådastöten – motståndet från Trump och Maga-rörelsen – i stället gjuta nytt liv i det amerikanska 50-talsformatet.
Lyme arthritis (LA) is a recognized manifestation of Lyme borreliosis in Sweden, but data on the causative Borrelia species are limited. This study aimed to describe the demographics of LA and identify Borrelia burgdorferi sensu lato (B. burgdorferi s.l.) genospecies present in synovial fluid (SF). Patient data were collected from the test requisition form accompanying consecutive SF samples submi
An animal possessing reversal learning ability is capable of unlearning a previously learnt association between a stimulus and a reward and learning a new contingency. It is a form of behavioural flexibility, which can be advantageous in changing environments. Serial reversal learning occurs when an animal's performance improves over repeated reversals of contingencies. In this study, we tested th
Context. Despite the ever-increasing number of known exoplanets, no uncontested detections have been made of their satellites, known as exomoons. Aims. The quest to find exomoons is at the forefront of exoplanetary sciences. Certain space-born instruments are thought to be suitable for this purpose. We show the progress made with the CHaracterising ExOPlanets Satellite (CHEOPS) in this field using
The Chicxulub impact triggered a massive extinction event marked by the Cretaceous-Paleogene boundary (K-Pg ∼66Ma), ejecting vast amounts of dust, molten, and vaporized materials. While impact spherules are interpreted as products of impactor and target lithologies, their precise composition and distribution remain insufficiently constrained. Although previous studies restrict impactor contaminati
OBJECTIVE: Diabetes significantly increases the risk for atherosclerotic complications, including coronary artery disease (CAD). Previous studies have suggested that adult-onset diabetes can be classified into five different clinical subtypes, including moderate obesity-related diabetes (MOD). The aim of this study was to investigate the genetic associations between the five diabetes subtypes and
Background: We aimed to investigate if early life marine n-3 fatty acids and fish intake, and fatty acid desaturase (FADS) genetic variants, were associated with later risk of celiac disease (CeD).Methods: Among 85,244 children in the prospective Norwegian Mother, Father, and Child Cohort Study, fish and marine fatty acid intakes were estimated from questionnaires to mothers during pregnancy, and
Biodiversity in human-dominated landscapes is declining, but evidence-based conservation targets to guide international policies for such landscapes are lacking. We present a framework for informing habitat conservation policies based on the enhancement of habitat quantity and quality and define thresholds of habitat quantity at which it becomes effective to also prioritize habitat quality. We app
BACKGROUND Clonal hematopoiesis of indeterminate potential (CHIP) and clonal cytopenia of undetermined significance (CCUS) are defined by somatic mutations in genes associated with myeloid neoplasms (MN) at a variant allele fraction (VAF) of 0.02 or greater in the absence and presence of cytopenia, respectively. CHIP/CCUS is highly prevalent in adults, and defining predictors of MN risk would aid
Aims. We aim to refine the fundamental parameters of the TOI-2141 planetary system, which includes a transiting sub-Neptune orbiting a Sun-like star on a relatively long orbit of 18.26 days, by combining new photometric and spectroscopic observations. Methods. We analyzed new space-based photometry from TESS and CHEOPS, as well as 61 radial velocity measurements from HARPS-N. We performed individu
