Analysis of IgM sub-variants related to ancestral tetraploidy in salmonid fish
(Doctoral thesis, 2013-03-21)Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) possess two paralogous IgM heavy chain (μ) genes related to ancestral tetraploidy. Accordingly, IgM subpopulations of Atlantic salmon and brown trout can be ... -
Analysis of immunoglobulin and T cell receptor gene expression in ballan wrasse (Labrus bergylta) revealed an extraordinarily high IgM expression in the gut
(Peer reviewed; Journal article, 2019)The serum IgM concentration of ballan wrasse is relatively high, estimated to approximately 13 mg/ml in adult wild fish of 800 g. The present study revealed an unusual high abundance of IgM mRNA in the gut of ballan wrasse. ... -
Analysis of reproductive traits reveals complex population dynamics on a small geographical scale in Atlantic herring
(Journal article; Peer reviewed, 2023-02-01)Atlantic herring (Clupea harengus) has a complex population structure and displays a variety of reproductive strategies. Differences in reproductive strategies among herring populations are linked to their time of spawning, ... -
Analysis of sequencing data in environmental genomics. Exploring the diversity of the microbial biosphere
(Doctoral thesis, 2013-04-12)Most life on this planet is microbial and for the last two decades, environmental genomics has contributed to reveal an impressive biodiversity of this microbial life. This approach applies DNA sequencing to environmental ... -
Analysis of transcription factor complexes and their associated chromatin interactions during erythropoiesis
(Doctoral thesis, 2014-01-17)Cis-regulatory elements can control gene transcription over large distances. Studying the association between cis-regulatory elements and the mechanism of gene regulation is important since the disruption in the transcriptional ... -
Anorectic role of high dietary leucine in farmed Atlantic salmon (Salmo salar L.): Effects on feed intake, growth, amino acid transporters and appetite-control neuropeptides
(Journal article; Peer reviewed, 2023)Leucine has been identified to modulate feed intake and energy homeostasis in fish as in other vertebrates. Under allostatic conditions, energy expenditure may change, and adjustments to the processes that govern the energy ... -
Anoxybacillus karvacharensis sp. nov., a novel thermophilic bacterium isolated from the Karvachar geothermal spring in Nagorno-Karabakh
(Journal article; Peer reviewed, 2021)Twelve thermophilic Anoxybacillus strains were isolated from sediment and water samples from a Karvachar hot spring located in the northern part of Nagorno-Karabakh. Based on phenotypic, chemotaxonomic and phylogenetic ... -
The antecedents and consequences of students´ autonomous motivation. The relation between need-support, motivation, and academic achievement
(Doctoral thesis, 2018-02-16)Higher education has traditionally rested on teacher-centred education. Recently, there has been a shift towards learner-centred education. Innovative teaching tools, active teaching methods, and teachers that encourages ... -
Anthropogenic disturbance modifies long-term changes of boreal mountain vegetation under contemporary climate warming
(Journal article; Peer reviewed, 2021)Aims Accelerating high-latitude climate warming drives shrub expansion in open landscapes and alters species distributions and compositions of plant communities. Simultaneously, various land use practices cause disturbance ... -
Anthropogenically impacted lake catchments in Denmark reveal low microplastic pollution
(Journal article; Peer reviewed, 2022)Microplastics have been detected in lake environments globally, including in remote regions. Agricultural and populated areas are known to congregate several inputs and release pathways for microplastic. This study ... -
Antibacterial treatment of lumpfish (Cyclopterus lumpus) experimentally challenged with Vibrio anguillarum, atypical Aeromonas salmonicida and Pasteurella atlantica
(Journal article; Peer reviewed, 2021)Lumpfish is a novel farmed species used as cleaner fish for the removal of lice from farmed salmon. As often with new, farmed species, there are challenges with bacterial infections. The frequency of prescription of ... -
Antibiotic sensitivity screening of Klebsiella spp. and Raoultella spp. isolated from marine bivalve molluscs reveal presence of CTX-M-producing K. pneumoniae
(Journal article; Peer reviewed, 2020-11)Klebsiella spp. are a major cause of both nosocomial and community acquired infections, with K. pneumoniae being responsible for most human infections. Although Klebsiella spp. are present in a variety of environments, ... -
Antibiotic uptake by cultured Atlantic cod leucocytes and effect on intracellular Francisella noatunensis subsp. noatunensis replication
(Peer reviewed; Journal article, 2014-02-04)The granuloma disease caused by Francisella noatunensis subsp. noatunensis in farmed Atlantic cod has not been successfully treated by use of antibacterials, even when antibacterial resistance testing indicates a sufficient ... -
Anticancer activity in Planctomycetes
(Peer reviewed; Journal article, 2019-01-07)There is a strong need to develop new drugs against many severe diseases. Therapy resistance is a major problem, for instance, in infectious diseases and cancer. Drug discovery has again turned to nature to search for ... -
