Role of Prdm genes in ectodermal and non-ectodermal neurogenesis in Nematostella vectensis
(Doctoral thesis, 2021-03-04)The origin and evolution of the nervous system is a long-standing question in biology to understand the complexity observed today. Developmentally, the nervous system arises from the outer germ layer: the ectoderm. ... -
Role of the class I PI3K p110ß and PtdIns(3,4,5)P3 in rRNA transcription in the nucleolus
(Master thesis, 2018-06-26)The phosphoinositide 3-kinase (PI3K) signalling pathway is one of the most altered pathways in human cancer. It is a complex pathway, when considering that ubiquitously expressed isoforms regulate different routes with ... -
Role of the kidneys in acid-base regulation and ammonia excretion in freshwater and seawater fish: implications for nephrocalcinosis
(Journal article; Peer reviewed, 2023)Maintaining normal pH levels in the body fluids is essential for homeostasis and represents one of the most tightly regulated physiological processes among vertebrates. Fish are generally ammoniotelic and inhabit diverse ... -
Roles of M-phase cell cycle regulatory paralogs in the urochordate Oikopleura dioica
(Doctoral thesis, 2018-11-16)Cell cycle progression is controlled by a series of regulators with complex spatialtemporal dynamics, ensuring faithful transitions of different phases. The urochordate Oikopleura has systemically employed diverse cell ... -
Roles of three putative salmon louse (Lepeophtheirus salmonis) prostaglandin E2 synthases in physiology and host–parasite interactions
(Journal article; Peer reviewed, 2021)Background The salmon louse (Lepeophtheirus salmonis) is a parasite of salmonid fish. Atlantic salmon (Salmo salar) exhibit only a limited and ineffective immune response when infested with this parasite. Prostaglandins ... -
Rotavirus Infection of Cells in Culture Induces Activation of RhoA and Changes in the Actin and Tubulin Cytoskeleton
(Peer reviewed; Journal article, 2012-10-17)Rotavirus infection induces an increase in [Ca2+]cyto, which in turn may affect the distribution of the cytoskeleton proteins in the infected cell. Changes in microfilaments, including the formation of stress fibers, were ... -
SAF-A/hnRNP U binds polyphosphoinositides via a lysine rich polybasic motif located in the SAP domain
(Journal article; Peer reviewed, 2023)Polyphosphoinositides (PPIn) play essential functions as lipid signalling molecules and many of their functions have been elucidated in the cytoplasm. However, PPIn are also intranuclear where they contribute to chromatin ... -
Safety and Reverence: How Roman Catholic Liturgy Can Respond to the COVID-19 Pandemic
(Journal article; Peer reviewed, 2021)The current COVID-19 pandemic is a major challenge for many religious denominations. The Roman Catholic Church strongly depends on physical communal worship and sacraments. Disagreements grow concerning the best balance ... -
Safety assessment of the functional feed additive phenylcapsaicin in a commercial broiler diet
(Journal article; Peer reviewed, 2023)Introduction: Intestinal colonisation of Salmonella is a major concern in the poultry industry, and a low dose of the high-purity synthetic capsaicin analogue phenylcapsaicin (PheCap) has the potential to be a phytobiotic ... -
Salamonid alphavirus (SAV) - genetic characterisation of a new subtype, SAV3, and implementation of a novel diagnostic method
(Doctoral thesis, 2006-12-13) -
Salmon lice as models for understanding life history evolution of parasites under intensive farming
(Doctoral thesis, 2017-06-20)Human activities are drastically changing ecological conditions for living organisms and this leads to evolutionary changes. One example is the appearance and spread of resistance against drugs and antibiotics, but we also ... -
Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
(Peer reviewed; Journal article, 2019)Atlantic salmon Salmo salar aquaculture is based on the use of open-pen sea cages, with the consequence that farmed fish are both recipients and sources of pathogens from surrounding waters. Currently, the parasitic salmon ... -
Salmon lice survive the straight shooter: A commercial scale sea cage trial of laser delousing
(Journal article; Peer reviewed, 2020)Ectoparasitic salmon louse (Lepeophtheirus salmonis) infestations are costly for Atlantic salmon (Salmo salar) farmers in Norway. As a result, there is a strong desire for solutions to prevent and control infestations, and ... -
The salmon louse genome: Copepod features and parasitic adaptations
(Journal article; Peer reviewed, 2021)Copepods encompass numerous ecological roles including parasites, detrivores and phytoplankton grazers. Nonetheless, copepod genome assemblies remain scarce. Lepeophtheirus salmonis is an economically and ecologically ... -
Salmon louse labial gland enzymes: implications for host settlement and immune modulation
(Journal article; Peer reviewed, 2024)Salmon louse (Lepeophtheirus salmonis) is a skin- and blood-feeding ectoparasite, infesting salmonids. While feeding, labial gland proteins from the salmon louse may be deposited on the Atlantic salmon (Salmo salar) skin. ... -
The salmon louse larval black box: evaluating fecundity and enumerating planktonic stages with an aquaculture management perspective
(Doctoral thesis, 2022-06-17)Modern salmon aquaculture began in 1970 with the innovation of at-sea fish pens which precipitated a rapid growth in production. The expansion of the industry and increased number of farmed fish concentrated within the ... -
The salmon louse Lepeophtheirus salmonis (Copepoda: Caligidae) life cycle has only two chalimus stages
(Peer reviewed; Journal article, 2013-09-12)Each year the salmon louse (Lepeophtheirus salmonis Krøyer, 1838) causes multi-million dollar commercial losses to the salmon farming industry world-wide, and strict lice control regimes have been put in place to reduce ... -
Salmonid fish: model organisms to study cardiovascular morphogenesis in conjoined twins?
(Peer reviewed; Journal article, 2016-07-16)Background: There is a gap in knowledge regarding the cardiovascular system in fish conjoined twins, and regarding the cardiovascular morphogenesis of conjoined twins in general. We examined the cardiovascular system in a ... -
