    • 3-Chloro-N′-(2-hydroxybenzylidene) benzohydrazide: An LSD1-Selective Inhibitor and Iron-Chelating Agent for Anticancer Therapy 

      Sarno, Federica; Papulino, Chiara; Franci, Gianluigi; Andersen, Jeanette hammer; Cautain, Bastien; Melardo, Colombina; Altucci, Lucia; Nebbioso, Angela; Andersen, Jeanette H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-07)
      Despite the discovery and development of novel therapies, cancer is still a leading cause of death worldwide. In order to grow, tumor cells require large quantities of nutrients involved in metabolic processes, and an increase in iron levels is known to contribute to cancer proliferation. Iron plays an important role in the active site of a number of proteins involved in energy metabolism, DNA ...
    • Access to fishing grounds and adaptive strategies. The case of Chorkor and Nungua Fishing Communities of Greater Accra, Ghana 

      Sobang, Nicholas Badidaamet (Master thesis; Mastergradsoppgave, 2014-05-15)
      Artisanal fisheries are increasingly been accepted as the panacea for exploiting marine resources in costal Ghana. However evidence mustered over the years indicate that the local fisher-folk who are engaged in small scale fisheries hardly get full participation in making decision governing these resources. The current study examine the factors that constrain fishers participation in decision making ...
    • Adjuvant activity of fish type I interferon shown in a virus DNA vaccination model 

      Chang, Chia Jung; Sun, Baojian; Robertsen, Børre (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-09)
      There is a need for more efficient vaccines to combat viral diseases of Atlantic salmon and other farmed fish. DNA vaccines are highly effective against salmonid rhabdoviruses, but have shown less effect against other viruses. In the present work we have studied if type I IFNs might be used as adjuvants in fish DNA vaccines. For this purpose we chose a DNA vaccine model based on the hemagglutin ...
    • Adjuvants and immunostimulants in fish vaccines: Current knowledge and future perspectives. 

      Tafalla, C; Bøgwald, Jarl; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Vaccination is the most adequate method to control infectious diseases that threaten the aquaculture industry worldwide. Unfortunately, vaccines are usually not able to confer protection on their own; especially those vaccines based on recombinant antigens or inactivated pathogens. Therefore, the use of adjuvants or immunostimulants is often necessary to increase the vaccine efficacy. Traditional ...
    • Advancing research for the management of long-lived species: A case study on the Greenland Shark 

      Edwards, Jena E.; Hiltz, Elizabeth; Broell, Franziska; Bushnell, Peter G.; Campana, Steven E.; Christiansen, Jørgen Schou; Devine, Brynn M.; Gallant, Jeffrey J.; Hedges, Kevin J.; MacNeil, M. Aaron; McMeans, Bailey C.; Nielsen, Julius; Præbel, Kim; Skomal, Gregory B.; Steffensen, John Fleng; Walter, Ryan P.; Watanabe, Yuuki Y.; VanderZwaag, David L.; Hussey, Nigel E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-02)
      Long-lived species share life history traits such as slow growth, late maturity, and low fecundity, which lead to slow recovery rates and increase a population’s vulnerability to disturbance. The Greenland shark (Somniosus microcephalus) has recently been recognized as the world’s longest-lived vertebrate, but many questions regarding its biology, physiology, and ecology remain unanswered. Here we ...

      Andrade Rodriguez, Hector Antonio (Master thesis; Mastergradsoppgave, 2003-06-05)
      The rose-spotted snapper, Lutjanus guttatus, seems to be sequentially exploited by the shrimp trawler and the artisanal fleet along the Pacific Coast of Guatemala. The growth parameters of the snapper were estimated in the present study with basis on material collected in two fishing harbours. Other biological and fishery information was compiled to simulate stock dynamics with a yield-per-recruit ...
    • Aldri mer 18. april! 

      Finstad, Bjørn-Petter; Holm, Petter (Chronicle; Kronikk, 2013-04-18)
      Den 18. april 1989 er et viktig vendepunkt i norsk fiskerihistorie. Det var den dagen Fiskeridepartementet stoppet kystflåtens fiske etter torsk nord for 62. breddegrad - midt i den tradisjonelle sesongen. Reaksjonene lot ikke vente på seg. Historiens første totalforbud mot å fiske torsk var “et sjokk til dyp ettertanke”, het det i Fiskeribladet.
    • Allocating quotas and limiting access. An approach to management. The case of the Norwegian mackerel fishery 

      Sand, Mona (Master thesis; Mastergradsoppgave, 2002-05-28)
      The mackerel fishery has become the most important pelagic species for export. Prior to 1994 the allocations between the three main fleet groups, the purse seine, the coastal and the trawl fleet was negotiated on an annual basis. 1994, was an important year for the fisheries industry, the price subsidies were no longer appropriate after the implementation of the EEA agreement. A stronger focus ...
    • Allochrony as a potential driver for reproductive isolation in adaptive radiations of European whitefish ecomorphs 

      Bitz-Thorsen, Julie; Häkli, Katja; Bhat, Shripathi; Præbel, Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-29)
      In northern Fennoscandian lakes, monophylogenetic lineages of postglacial fishes are radiating into several adaptive forms, but the speciation process is still at an incipient stage. The speciation process has received increased attention over the years, but the underlying mechanisms and drivers are still debated and poorly understood. European whitefish (<i>Coregonus lavaretus</i> [L.]) is the most ...

    • Analysis of marine aquaculture developments in Namibia. Environmental, economic and legislative considerations 

      Iitembu, Johannes Angala (Master thesis; Mastergradsoppgave, 2005-05-30)
      This multidisciplinary analysis of Namibia marine aquaculture developments has found it to have a good potential. Existing Namibian aquaculture laws are comprehensive in nature controlling aspects such as water, land, public health, sanitation and disease, however they ignore fish welfare. Mean temperature of Namibian marine coastal waters in the150 m water depth strata has averaged at 14.07 oC for ...
    • Analysis of the chokka squid : Loligo reynaudi d`Orbigny, 1845 : log-book data in South Africa 

      Ntola, Busisiwe Precious (Master thesis; Mastergradsoppgave, 2010-05-14)
      The total annual catch from the log-book and Food & Agriculture Organization were compared. Annual catch per unit effort of the Loligo reynaudi was investigated. There were five vessel size groups and eight fishing areas identified. A Simple Analysis of Variance was used to test the effect of the year, quarter, region, area on the CPUE and General Linear Model was used to standardize the CPUE. The ...

      Mensah, Isaac (Master thesis; Mastergradsoppgave, 2010-11-30)
      The tuna fishery is an important sector in Ghana. In 2009, total landing of tuna in Ghana represented about 24% of total catches in the East Atlantic. Canned tuna is Ghana’s most important non-traditional export commodity in terms of foreign exchange earnings. The main focus of this thesis is to analyze the performance of Ghanaian canned tuna export to the EU -27 market. Performance is measured in ...
    • Anti-Cancer Potential of Homemade Fresh Garlic Extract Is Related to Increased Endoplasmic Reticulum Stress 

      Petrovic, Voin; Nepal, Anala; Olaisen, Camilla; Bachke, Siri; Hira, Jonathan; Søgaard, Caroline Krogh; Røst, Lisa Marie; Misund, Kristine; Andreassen, Trygve; Melø, Torun Margareta; Bartosova, Zdenka; Bruheim, Per; Otterlei, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-05)
      The use of garlic and garlic-based extracts has been linked to decreased incidence of cancer in epidemiological studies. Here we examine the molecular and cellular activities of a simple homemade ethanol-based garlic extract (GE). We show that GE inhibits growth of several different cancer cells in vitro, as well as cancer growth in vivo in a syngeneic orthotopic breast cancer model. Multiple myeloma ...

    • Anti-Infective Effect of Adhesive Probiotic Lactobacillus in Fish is Correlated with Their Spatial Distribution in the Intestinal Tissue 

      He, Suxu; Ran, Chao; Qin, Chubin; Li, Shuning; Zhang, Hongling; de Vos, Willem M.; Ringø, Einar; Zhou, Zhigang (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-16)
      In this study, we tested the distribution of 49 Lactobacillus strains in the mucus and mucosa of the intestine tissue of zebrafish. We observed a progressive change in the spatial distribution of Lactobacillus strains, and suggested a division of the strains into three classes: mucus type (>70% in mucus), mucosa type (>70% in mucosa) and hybrid type (others). The hybrid type strains were more efficient ...
