    • Evaluation of the performance of two prediction models, the IrisPlex and the novel EC12 model, for eye colour predictions in a Norwegian population. 

      Kjersem, Marianne (Mastergradsoppgave; Master thesis, 2020-06-12)
      Biological material obtained from a crime scene is used to generate DNA-profile by typing short tandem repeat (STR) markers. However, if the STR-profile do not match the DNA profile of suspects or from a crime DNA database, the investigation can go towards typing markers that can estimate externally visible characteristics (EVCs). EVCs can function as a “biological witness” and thus aid a police ...

In nonHodgkin lymphoma (NHL), ASCT is usually performed after relapse with curative intent. Disease progression is often associated with increased angiogenesis, in which endothelial progenitor cells ...
    • Health and diseases of semi-domesticated reindeer in a climate change perspective 

      Tryland, Morten; Åhman, Birgitta; Sanchez Romano, Javier (Chapter; Bokkapittel, 2022-04-21)
      Climate change may affect reindeer herding and the health and disease of reindeer in several ways. One way of mitigating such changes is supplementary feeding, both in corrals and by bringing fodder to the animals on natural pastures. Feeding, when the right feed and feeding regime are used, may compensate for the loss of natural pastures and increase animal welfare. However, feeding may also cause ...

      Gabrielsen, Mari; Ravna, aina westrheim; Kristiansen, kurt; Sylte, Ingebrigt (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-06-14)
      The serotonin (5-HT) transporter (SERT) plays an important role in the termination of 5-HT-mediated neurotransmission by transporting 5-HT away from the synaptic cleft and into the presynaptic neuron. In addition, SERT is the main target for antidepressant drugs, including the selective serotonin reuptake inhibitors (SSRIs). The three-dimensional (3D) structure of SERT has not yet been determined, ...
    • Analysis of 30 Y-chromosomal STR markers in the Norwegian population 

      Støtvig, Ingrid (Mastergradsoppgave; Master thesis, 2019-05-15)
      Autosomal STR-analysis is the standard method of DNA-typing in casework. However, there are forensic sample types that may contain a large fraction of female DNA and a minimal fraction of male DNA. The male fraction may not be successfully amplified using autosomal STR-analysis because it “drowns” in the female fraction. However, the analysis of male-specific YSTR markers may circumvent this obstacle. ...
