Female sex hormones and subtypes of breast cancer
(Doctoral thesis; Doktorgradsavhandling, 2025-02-20)Bakgrunn: Det er gode holdepunkter for at kvinnelige kjønnshormoner har en avgjørende rolle i utviklingen av brystkreft. Subtyper av brystkreft utgjør distinkte sykdomsentiteter og har ulik etiologi, risikofaktorer og prognoser. Disse subtypene er ofte klassifisert som luminal A-lignende, luminal B-lignende, HER2-positiv og trippel-negativ brystkreft (TNBC) basert på immunhistokjemisk undersøkelse. ... -

However, whether the hypothalamic-pituitary-adrenal (HPA) axis-immune regulation is disrupted in SZ and BD, is yet to be determined.<p> <p>Methods - Cortisol and C-reactive protein (CRP) were measured in blood samples collected at or before 10 am in ... -
Non-Standard Errors
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-17)In statistics, samples are drawn from a population in a data‐generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence‐generating process (EGP). We claim that EGP variation across researchers adds uncertainty—nonstandard errors (NSEs). We study NSEs by letting 164 teams test the same ... -
Long Covid: a global health issue - a prospective, cohort study set in four continents
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-21)Introduction - A proportion of people develop Long Covid after acute COVID-19, but with most studies concentrated in high-income countries (HICs), the global burden is largely unknown. Our study aims to characterise long-term COVID-19 sequelae in populations globally and compare the prevalence of reported symptoms in HICs and low-income and middle-income countries (LMICs).<p> <p>Methods - A ... -
Agent-based modeling: Insights into consumer behavior, urban dynamics, grid management, and market interactions
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-01-03)A future sustainable energy system is expected to be digital, de-central, de-carbonized, and democratized. As the transition unfolds, new and diverse actors of various sizes will emerge in different segments. Thereby, the future energy system could shift its attention to the actors’ behavior than finding an optimum based on the physical system. Agent based modeling tools can reflect decisions from ... -
Extracellular traps in skin lesions infected with lymphocystis disease virus in black rockfish (Sebastes schlegelii)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-18)The lymphocystis disease (LCD), caused by Lymphocystis disease virus (LCDV), is a benign and self-limiting disease described in a many freshwater and marine fish species. Hypertrophic fibroblasts and extensive aggregation of inflammatory cells are characteristics of LCD. In the present study, small animal imaging and ultrastructural investigations were carried out on the lymphocystis nodules of black ... -
Effects of prolonged application of peracetic acid-based disinfectant on recirculating aquaculture systems stocked with Atlantic salmon parr
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-07)The use of recirculating aquaculture systems (RAS) for Atlantic salmon (Salmo salar) production has become increasingly common. RAS water disinfection plays a crucial role on its biosecurity. Peracetic acid (PAA) is a promising disinfectant due to its powerful oxidative properties, broad antimicrobial spectrum, and rapid degradation into no harmful compounds. This study focused on assessing the ... -
Ontogeny of myeloperoxidase (MPO) positive cells in flounder (Paralichthys olivaceus)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-10)Neutrophils represent an important asset of innate immunity. Neutrophils express myeloperoxidase (MPO) which is a heme-containing peroxidase involved in microbial killing. In this study, by using real-time quantitative PCR and Western blot analysis, the flounder MPO (PoMPO) was observed to be highly expressed in the head kidney, followed by spleen, gill, and intestine during ontogeny – during ... -

Browning events in Arctic ecosystems: Diverse causes with common consequences
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-01-27)Arctic ecosystems are experiencing extreme climatic, biotic and physical disturbance events that can cause substantial loss of plant biomass and productivity, sometimes at scales of >1000 km2. Collectively known as browning events, these are key contributors to the spatial and temporal complexity of Arctic greening and vegetation dynamics. If we are to properly understand the future of Arctic ... -
Giant viruses inhibit superinfection by downregulating phagocytosis in Acanthamoeba
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-03)In the context of the virosphere, viral particles can compete for host cells. In this scenario, some viruses block the entry of exogenous virions upon infecting a cell, a phenomenon known as superinfection inhibition. The molecular mechanisms associated with superinfection inhibition vary depending on the viral species and the host, but generally, blocking superinfection ensures the genetic supremacy ...
