Variability in Resting-State Functional Magnetic Resonance Imaging: The Effect of Body Mass, Blood Pressure, Hematocrit, and Glycated Hemoglobin on Hemodynamic and Neuronal Parameters
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-13)Introduction: Replicability has become an increasing focus within the scientific communities with the ongoing ‘‘replication crisis.’’ One area that appears to struggle with unreliable results is resting-state functional magnetic resonance imaging (rs-fMRI). Therefore, the current study aimed at improving the knowledge of endogenous factors that contribute to inter-individual variability. Methods: ... -
Zooplankton assemblages along the North American Arctic: Ecological connectivity shaped by ocean circulation and bathymetry from the Chukchi Sea to Labrador Sea
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-09)We defined mesozooplankton biogeography in the North American Arctic to elucidate drivers of biodiversity, community structure, and biomass of this key component of the Arctic marine ecosystem. A multivariate analysis identified four mesozooplankton assemblages: Arctic-oceanic, Arctic-shelf, Coastal-Hudson, and Labrador Sea. Bathymetry was a major driver of the distribution of these assemblages. ... -

Translucency and Color Stability of a Simplified Shade Nanohybrid Composite after Ultrasonic Scaling and Air-Powder Polishing
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-15)We aimed to assess the influence of professional dental prophylaxis on the translucency and color stability of a novel simplified shade nanohybrid composite material. Sixty composite disks (5 mm in diameter and 2 mm thick) of light (n = 30) and dark (n = 30) shades were prepared. The specimens were randomly divided into the following three groups (n = 10) according to the prophylaxis procedure ... -
Disruption of marine habitats by artificial light at night from global coastal megacities
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-01)Half of globally significant megacities are situated near the coast, exposing urban marine ecosystems to multiple stressors such as waste-water discharge containing a host of organic and inorganic pollutants, air and noise pollution. In addition to these well recognized sources, artificial light at night (ALAN) pollution is inseparable from cities but poorly quantified in marine ecosystems to date. ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-01)Sex differences in chronic pain are well established with documented predominance in women. This study assessed relationships between age at menarche and chronic pain, site-specific chronic pain, pain characteristics, and chronic widespread pain (CWP). We used data from the Tromsø Study conducted in 2007 to 2008 and 2015 to 2016 (Tromsø 6 and Tromsø 7 waves) including participants aged 30 to 99 ... -
Should SVGp12 Be Used for JC Polyomavirus Studies? Comment on Prezioso et al. COS-7 and SVGp12 Cellular Models to Study JCPyV Replication and MicroRNA Expression after Infection with Archetypal and Rearranged-NCCR Viral Strains. Viruses 2022, 14, 2070
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-29)A recent paper in Viruses investigates the impact of the JC polyomavirus (JCPyV) microRNA on the replication of different JCPyV strains. Unfortunately, one of the cell lines used, the human fetal glial cell line SVGp12, is productively infected by the closely related BK polyomavirus (BKPyV), which may confound results. Scientists need to take this into account and the potential pitfalls. -
Omicron Variant Generates a Higher and More Sustained Viral Load in Nasopharynx and Saliva Than the Delta Variant of SARS-CoV-2
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-31)The Omicron variant of SARS-CoV-2 spreads more easily than earlier variants, possibly as a result of a higher viral load in the upper respiratory tract and oral cavity. Hence, we investigated whether the Omicron variant generates a higher viral load than that of the Delta variant in saliva and nasopharynx. Both specimens were collected from 52 Omicron and 17 Delta cases at two time points one week ... -
Stable cerebrospinal fluid neurogranin and β-site amyloid precursor protein cleaving enzyme 1 levels differentiate predementia Alzheimer's disease patients
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-24)Cerebrospinal fluid (CSF) β-site amyloid precursor protein cleaving enzyme 1 (BACE1), neurogranin and the neurogranin/BACE1 ratio are proposed markers for Alzheimer’s disease. BACE1 is also a drug target. However, CSF levels may differ between early-stage amyloid plaque formation (A) and later stage downstream tau-tangle pathology (T) and neurodegeneration (N) and may be expressed as an A/T/N stage ... -
Theoretical Basis for a Group Intervention Aimed at Preventing High School Dropout: The Case of ‘Guttas Campus’
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-18)School dropout may have important negative consequences for the individual as well as for society. It is therefore important to help students stay in school. Group interventions have been developed to reduce dropout, but the theoretical underpinnings of such programs are not always obvious. This study focuses on the Norwegian dropout-prevention program named ‘Guttas Campus’ (The Boys’ Camp). We draw ... -
Improved bycatch reduction in the mixed demersal trawl fishery for Norway pout (Trisopterus esmarkii)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-22)In this study, we compared the bycatch reduction capacity of a trawl fitted with a standard rigid sorting grid with that of a trawl fitted with a newly developed, flexible system called the Excluder. We conducted the fishing trials in the Norway pout (Trisopterus esmarkii) small-meshed trawl fishery in the North Sea. Catch data were analysed by species and length using the catch comparison and catch ... -
Escape, discard and landing probability of Nephrops norvegicus in the Mediterranean Sea creel fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-22)Size selection in creel fishery consists of two processes: the first taking place in the creel on the seabed and the second made by the fisher on the vessel. However, no study has ever considered both processes when assessing the size selection in creel fisheries. This study presents a framework for including both and demonstrates it to predict the effect of mesh size and shape on the creel fishery ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-12)Background - Aboriginal women and their infants experience significant disadvantage in health outcomes compared to their non-Aboriginal counterparts. Access to timely, effective, and appropriate maternal and child health care can contribute to reducing these existing health disparities. This research sought to explore factors that contribute to continuity of care for Aboriginal women and their infants ... -
Pharmacodynamic properties for inhibition of cAMP- and cGMP elimination by pentoxifylline remain unaltered in vitro during hypothermia
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-15)Background - Rewarming from hypothermia is associated with severe complications, one of which is hypothermia-induced cardiac dysfunction. This condition is characterized by decreased cardiac output accompanied by increased total peripheral resistance. This contributes to mortality rate approaching 40%. Despite this, no pharmacological interventions are recommended for these patients below 30 °C. ... -

Evidence that heat acclimation training may alter sleep and incidental activity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-10)This randomized cross-over study tested the hypothesis that heat acclimation training would detrimentally affect sleep variables and alter incidental physical activity compared to a thermoneutral training control condition. Eight recreationally trained males (V̇ O2peak 49±4.9 mL. kg<sup>-1</sup>.min<sup>-1</sup>) completed two separate interventions separated by at least 31 days: 5 consecutive day ...
