(Master thesis / Masteroppgave, 2014)Lumbar disc herniation may affect the spinal nerve roots through mechanical pressure, but may also induce a local inflammatory response. Therefore, in an animal model mimicking the clinical situation after intervertebral ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Intimin and Invasin are prototypical inverse (Type Ve) autotransporters and important virulence factors of enteropathogenic Escherichia coli and Yersinia spp. respectively. In addition to a C‐terminal extracellular domain ...
-
Intra-colony venom diversity contributes to maintaining eusociality in a cooperatively breeding ant (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Background Eusociality is widely considered to evolve through kin selection, where the reproductive success of an individual’s close relative is favored at the expense of its own. High genetic relatedness ...
-
(Master thesis / Masteroppgave, 2020)Fish farming is the most common form of aquaculture. Its production contributes close to 50% of total global fish production, and is estimated to increase to 62% by year 2030. Piscirickettsiosis and francisellosis are two ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The Fungi are a diverse kingdom, dominating terrestrial environments and driving important ecologies. Although fungi, and the related Opisthosporidia, interact with photosynthetic organisms on land and in freshwater as ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Ricin can be isolated from the seeds of the castor bean plant (Ricinus communis). It belongs to the ribosome-inactivating protein (RIP) family of toxins classified as a bio-threat agent due to its high toxicity, stability ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Tumor progression is a complex process consisting of several steps characterized by alterations in cellular behavior and morphology. These steps include uncontrolled cell division and proliferation, invasiveness and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Cuticular hydrocarbons (CHCs) cover the cuticle of insects and serve as desiccation barrier and as semiochemicals. While the main enzymatic steps of CHC biosynthesis are well understood, few of the underlying genes have ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)Hybridization increases genetic variation, hence hybrid species may have greater evolutionary potential once their admixed genomes have stabilized and incompatibilities have been purged. Yet, little is known about how such ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Seoul hantavirus (SEOV) has recently raised concern by causing geographic range expansion of hemorrhagic fever with renal syndrome (HFRS). SEOV infections in humans are significantly underestimated worldwide and epidemic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Understanding the drivers (internal and external) that determine the productivity of marine ecosystems is challenging. For example, the correct estimate of recruitment is essential to estimate fish stock abundance. In this ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract To understand how species evolve and adapt to changing environments, it is important to study gene flow and introgression due to their influence on speciation and radiation events. Here, we apply a novel ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The Invariant chain (Ii, CD74) is a multifunctional regulator of adaptive immune responses and responsible for sorting MHC-I, MHC-II and other Ii-associated molecules to a specific endosomal pathway. When Ii is expressed, ...
-
(Master thesis / Masteroppgave, 2022)Genomic variation is the key to speciation and evolution. Genomic variants underlie how species change, adapt, and evolve and range from single-point mutations to large chromosomal rearrangements. Inversions are an example ...
-
(Master thesis / Masteroppgave, 2021)Rapid climatic changes already affect ecosystems all over the globe. Trichaptum abietinum has a wide geographic distribution covering large climatic gradients, which could indicate adaptation to local environments in ...
-

-
(Master thesis / Masteroppgave, 2020)Character displacement has been a process discussed by biologist ever since Darwin visited the Galapagos in the 19th century. Similar species occurring together will sometimes diverge in characters to avoid hybridization ...

Investigating the cellular mechanism of muscle memory in female mice subjected to testosterone treatmentRestricted Access (Master thesis / Masteroppgave, 2021)
-
(Master thesis / Masteroppgave, 2020)The surface of Gram-negative bacteria is perforated by β-barrel proteins called outer membrane proteins (OMPs). These β-barrels are integral to the outer membrane (OM) and are essential for the viability of the bacterial ...
