The ABC (ATP binding cassette) transporters human P-glycoprotein (ABCB1) and the human MRP5 (ABCC5) are involved in multidrug resistance. Results: In order to elucidate structural and molecular concepts of multidrug resistance, we have constructed a molecular model of the ...
    • Cyanobacterial ribosomal RNA genes with multiple, endonuclease-encoding group I introns 

      Haugen, Peik; Bhattacharya, Debashish; Palmer, Jeffrey D.; Turner, Seán; Lewis, Louise A.; Pryer, Kathleen M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-09-08)
      Background: Group I introns are one of the four major classes of introns as defined by their distinct splicing mechanisms. Because they catalyze their own removal from precursor transcripts, group I introns are referred to as autocatalytic introns. Group I introns are common in fungal and protist nuclear ribosomal RNA genes and in organellar genomes. In contrast, they are rare in all other ...
    • Risikovurdering; import og spredning av tarmpatogene bakterier med krydder og urter 

      Rimstad, Espen; Høiby, E. Arne; Kapperud, Georg; Lassen, Jørgen Fredrik; Lunestad, Bjørn Tore; Nygård, Karin Maria; Olsvik, Ørjan; Nesbakken, Truls; Robertson, Lucy; Tryland, Morten; Tranulis, Michael A.; Vainio, Kirsti; Blom, Hans (Research report; Forskningsrapport, 2007-09-26)
      Forbruket av krydder i Norge øker og ligger per i dag på vel ½ kg per person og år (2006). Forbruket hos oss er imidlertid fortsatt langt lavere enn i enkelte andre industriland (eksempelvis USA med et forbruk på 1,6 kilo per person og år) og vil derfor sannsynligvis fortsatt øke ganske betydelig. Også antall ulike kryddertyper øker, parallelt med økende interesse for ”eksotisk” (ikke minst asiatisk) ...

      Sørensen, Karen K.; Josefsen, Terje D.; Mørk, Torill; Mathiesen, Svein D.; Ryeng, Kathrine A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-09-28)
      Background: In a project to determine the causes of winter mortality in reindeer in Finnmark County, northern Norway, the most frequent diagnosis turned out to be complete emaciation, despite several of the reindeer having been given silage for up to 4 weeks before they died. The present paper describes autopsy results and other findings in these animals. Methods: Autopsies were made of 32 ...
    • Transgenic mice expressing constitutive active MAPKAPK5 display gender-dependent differences in exploration and activity 

      Moens, Ugo; Van Belle, Werner; Gerits, Nancy (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-11-12)
      Background The mitogen-activated protein kinases, MAPKs for short, constitute cascades of signalling pathways involved in the regulation of several cellular processes that include cell proliferation, differentiation and motility. They also intervene in neurological processes like fear conditioning and memory. Since little remains known about the MAPK-Activated Protein Kinase, MAPKAPK5, we constructed ...

    • Use of Complementary and Alternative Medicine Among Patients: Classification Criteria Determine Level of Use 

      Kristoffersen, Agnete Egilsdatter; Fønnebø, Vinjar; Norheim, Arne Johan (Journal article; Tidsskriftartikkel; Peer reviewed, 2008)
      Background and objectives: Self-reported use of complementary and alternative medicine (CAM) among patients varies widely between studies, possibly because the definition of a CAM user is not comparable. This makes it difficult to compare studies. The aim of this study is to present a six-level model for classifying patients' reported exposure to CAM. Prayer, physical exercise, special diets, ...

    • Forty years of allocated seats for Sami medical students : has preferential admission worked? 

      Gaski, Margrete; Abelsen, Birgit; Hasvold, Toralf (Journal article; Tidsskriftartikkel; Peer reviewed, 2008)
      This article examines the effects of a special admission policy for Sami medical students in Norway. In the 1960s, public health and health care were found to be poorer in Sami communities than in the rest of Norway. There were few doctors and none of them spoke Sami. Sami school leavers found it difficult to gain admittance to medical schools. In response to this situation, the medical faculty at ...
