Ancient origin and genetic segregation of canine circovirus infecting arctic foxes (Vulpes lagopus) in Svalbard and red foxes (Vulpes vulpes) in Northern Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-12)Canine circovirus (CanineCV) is a relatively new viral species, belonging to the family <i>Circoviridae</i>, whose pathogenic role is still uncertain. Since its first description in one domestic dog in 2011 from the USA, several reports have been documenting its distribution worldwide. Recently, CanineCV was also detected in wild animals such as wolves, foxes and badgers. In order to investigate the ... -
Why does Russia have such high cardiovascular mortality rates? Comparisons of blood-based biomarkers with Norway implicate non-ischaemic cardiac damage
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-15)<p><i>Background - </i>Russia has one of the highest rates of mortality from cardiovascular disease (CVD). At age 35–69 years, they are eight times higher than in neighbouring Norway. Comparing profiles of blood-based CVD biomarkers between these two populations can help identify reasons for this substantial difference in risk. <p><i>Methods - </i>We compared age-standardised mean levels of CVD ... -
Eat or sleep: Availability of winter prey explains mid-winter and spring activity in an Arctic Calanus population
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-25)Copepods of the genus <i>Calanus</i> have adapted to high levels of seasonality in prey availability by entering a period of hibernation during winter known as diapause, but repeated observations of active <i>Calanus</i> spp. have been made in January in high latitude fjords which suggests plasticity in over-wintering strategies. During the last decade, the period of Polar Night has been studied ... -
Physical activity and blood gene expression profiles: the Norwegian Women and Cancer (NOWAC) Post-genome cohort
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-11)<i>Objectives</i> - The influence of physical activity (PA) on the immune system has emerged as a new field of research. Regular PA may promote an anti-inflammatory state in the body, thus contributing to the down-regulation of pro-inflammatory processes related to the onset and progression of multiple diseases. We aimed to assess whether overall PA levels were associated with differences in blood ... -

Protein kinase C isozymes associated with relapse free survival in non-small cell lung cancer patients
(Journal article; Tidsskriftartikkel, 2020-11-25)<i>Introduction</i>: Protein expression is deregulated in cancer, and the proteomic changes observed in lung cancer may be a consequence of mutations in essential genes. The purpose of this study was to identify protein expression associated with prognosis in lung cancers stratified by smoking status, molecular subtypes, and EGFR-, TP53-, and KRAS-mutations.<p> <p><i>Methods</i>: We performed ... -
On Automated Classification of Sea Ice Types in SAR Imagery
(Doctoral thesis; Doktorgradsavhandling, 2021-03-12)With the Arctic sea ice continuously decreasing in both extent and thickness, fast and robust production of reliable ice charts becomes more important to ensure the safety of Arctic operations. This thesis focuses on the development of automated algorithms for the mapping of sea ice from synthetic aperture radar (SAR) images. It presents a thorough background on the topics of sea ice observations ... -
Incident Angle Dependence of Sentinel-1 Texture Features for Sea Ice Classification
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-04)Robust and reliable classification of sea ice types in synthetic aperture radar (SAR) images is needed for various operational and environmental applications. Previous studies have investigated the class-dependent decrease in SAR backscatter intensity with incident angle (IA); others have shown the potential of textural information to improve automated image classification. In this work, we investigate ... -

Processing Code-Switches in the Presence of Others: An ERP Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-26)Code-switching is highly socially constrained. For instance, code-switching is only felicitous when those present are fluent in both languages. This means that bilinguals need to dynamically adjust their language control and expectation of code-switching to the current social situation or context. The aim of the present EEG study was to investigate how and when language control in the comprehension ... -
No Bilingual Benefits Despite Relations Between Language Switching and Task Switching
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-24)Previous research has shown that bilingual children outperform monolinguals on tasks testing cognitive control. Bilinguals’ enhanced cognitive control is thought to be caused by the necessity to exert more language control in bilingual compared to monolingual settings. Surprisingly, between-group research of cognitive effects of bilingualism is hardly ever combined with within-group research that ... -

Determination of the Dielectric Properties of Marine Surface Slicks Using Synthetic Aperture Radar
(Doctoral thesis; Doktorgradsavhandling, 2021-03-03)Over the course of the last three decades, Synthetic Aperture Radar (SAR) has proven itself to be an effective monitoring technology for marine applications. The clear benefits of using SAR as opposed to optical devices is that SAR is insensitive to cloud cover, lighting conditions and can also provide imagery to a high degree of resolution. Given these benefits, there is a large incentive to implement ... -
NADPH oxidase 2 mediates myocardial oxygen wasting in obesity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-19)Obesity and diabetes are independent risk factors for cardiovascular diseases, and they are associated with the development of a specific cardiomyopathy with elevated myocardial oxygen consumption (MVO<sub>2</sub>) and impaired cardiac efficiency. Although the pathophysiology of this cardiomyopathy is multifactorial and complex, reactive oxygen species (ROS) may play an important role. One of the ...
