Dye tracing of upward brine migration in snow
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-19)Salt is often present in the snow overlying seasonal sea ice, and has profound thermodynamic and electromagnetic effects. However, its provenance and behaviour within the snow remain uncertain. We describe two investigations tracing upward brine movement in snow: one conducted in the laboratory and one in the field. The laboratory experiments involved the addition of dyed brine to the base of ... -
A novel clinical prediction model for hip fractures: a development and validation study in the total population of Sweden
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-05)Background - Low bone density and osteoporosis are indications for bone-specific treatment. However, given the limited availability of bone density data in clinical practice and the fact that most patients with hip fracture do not have osteoporosis, accurate prediction of hip fracture risk in the absence of bone density data would be crucial.<p> <p>Methods - This development and validation study ... -

Elucidating the power of arginine restriction: taming type I interferon response in breast cancer via selective autophagy
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-18)Background - Type I interferons (IFN-I) are potent alarm factors that initiate cancer cell elimination within tumors by the immune system. This critical immune response is often suppressed in aggressive tumors, thereby facilitating cancer immune escape and unfavorable patient outcome. The mechanisms underpinning IFN-I suppression in tumors are incompletely understood. Arginase-1 (ARG1)-expressing ... -
Linking metabolism and histone acetylation dynamics by integrated metabolic flux analysis of Acetyl-CoA and histone acetylation sites
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-19)Objectives - Histone acetylation is an important epigenetic modification that regulates various biological processes and cell homeostasis. Acetyl-CoA, a hub molecule of metabolism, is the substrate for histone acetylation, thus linking metabolism with epigenetic regulation. However, still relatively little is known about the dynamics of histone acetylation and its dependence on metabolic processes, ... -
Instruction-guided deidentification with synthetic test cases for Norwegian clinical text
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024)Deidentification methods, which remove directly identifying information, can be useful tools to mitigate the privacy risks associated with sharing healthcare data. However, benchmarks to evaluate deidentification methods are themselves often derived from real clinical data, making them sensitive themselves and therefore harder to share and apply. Given the rapid advances in generative language ... -
A systematic survey of 200 systematic reviews with network meta-analysis (published 2020-2021) reveals that few reviews report structured evidence summaries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-26)Objectives - To map whether and how systematic reviews (SRs) with network meta-analysis (NMA) use presentation formats to report (a) structured evidence summaries – here defined as reporting of effects estimates in absolute effects with certainty ratings and with a method to rate interventions across one or more outcome(s) – and (b) NMA results in general.<p> <p>Study Design and Setting - We ... -
The long non-coding RPPH1 is decreased in leukocytes and increased in plasma from women developing pre-eclampsia†
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-30)Previous studies show differentially expressed long non-coding RNA present in the placenta from women with pre-eclampsia, potentially playing a vital role in the pathogenesis of the complication. In a published microarray study, Ribonuclease P RNA component H1 was decreased in leukocytes from women that later developed pre-eclampsia. We hypothesized that Ribonuclease P RNA component H1 decreased ... -
Summer and polar night diets of polar cod Boreogadus saida and Atlantic cod Gadus morhua in Kongsfjorden, Svalbard, Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-17)Rapid Atlantification of marine ecosystems in the Svalbard Archipelago (Norway) is posing a threat to the local polar cod (Boreogadus saida) population. In Kongsfjorden, the decreasing population of polar cod is experiencing a shift in their prey community from Arctic to Atlantic zooplankton and fish. Simultaneously, the abundance of Atlantic cod Gadus morhua is increasing. In this study, we explore ... -
Family health care needs in a paediatric population 6 months after moderate and severe physical trauma
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-29)Background: Traumatic injury is a leading cause of death and disability in children and young adults. There is a lack of evidence-based literature and guidelines on supporting families after severe child injury. This study aimed to assess the family needs and factors associated with those needs. Methods: A prospective multicenter follow-up study conducted at two Norwegian trauma centers involving ... -
The Sámi Pathfinders: Addressing the Knowledge Gap in Norwegian Mainstream Education
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-02)For at least two decades, lack of knowledge about the Sámi in Norway has been recognised as a reason for the perpetuation of stereotypes and discriminatory acts and hate speech towards them. Education about the Sámi, their lifeways, culture and rights is posited as a means of closing this gap, with the intention of influencing the majority Norwegian society’s attitudes towards the Sámi. The ... -
A new species of Lysinoe (Gastropoda: Helicoidea) from the Oligocene of Mexico
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-27)In her 1945 study on the Tertiary fossil mollusks of northeastern Mexico, Gardner listed only 2 taxa of land snails: Holospira eva Gardner, 1945 and “Helix” sp. The latter is recognized here as a new species of Lysinoe Adams & Adams, 1855 (Helicoidea, Xanthonychidae). The new species can be diagnosed from its congeners by its flattened shell profile, a lower body whorl with a faint angulation on ... -
The Relative Prevalence of Wave Packets and Coherent Structures in the Inertial and Kinetic Ranges of Turbulence as Seen by Solar Orbiter
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-08-16)The Solar Orbiter (SO) mission provides the opportunity to study the evolution of solar wind turbulence. We use SO observations of nine extended intervals of homogeneous turbulence to determine when turbulent magnetic field fluctuations may be characterized as: (i) wave packets and (ii) coherent structures (CSs). We perform the first systematic scale-by-scale decomposition of the magnetic field ... -
“Without IPS I Think I Would Really Fall Apart”: Individual Placement and Support as Experienced by People With Mental Illness—Phenomenological Peer Research Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-21)Having a job is an important component of recovery from mental illness and a source of economic, social, and health benefits. Most people experiencing severe mental illness (SMI) want to work but are excluded from employment opportunities. Employment specialists (ESs) working in individual placement and support (IPS) teams help persons struggling with SMI obtain competitive employment. This study ... -

Incidence angle dependency and seasonal evolution of L and C-band SAR backscatter over landfast sea ice
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-02)We estimate sea-ice type specific incidence angle (IA) dependencies for dual polarized (HH/HV) L and C-band synthetic aperture radar (SAR) for the winter, melt onset and advanced melt seasons for level and deformed ice, using time-series of Advanced Land Observing Satellite-2 (ALOS-2) and Sentinel-1 imagery off the north-east coast of Greenland. The IA dependencies are used to radiometrically ... -
Relative fluid stretching and rotation for sparse trajectory observations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-03)As most mathematically justifiable Lagrangian coherent structure detection methods rely on spatial derivatives, their applicability to sparse trajectory data has been limited. For experimental fluid dynamicists and natural scientists working with Lagrangian trajectory data via passive tracers in unsteady flows (e.g. Lagrangian particle tracking or ocean buoys), obtaining material measures of ... -
