(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2001)Type-B T cells raised against the immunodominant peptide in hen egg lysozyme (HEL(48-62)) do not respond to whole lysozyme, and this has been thought to indicate that peptide can bind to I-A(k) in different conformations. ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2002)Mucosal surfaces are protected by polymeric immunoglobulins that are transported across the epithelium by the polymeric immunoglobulin receptor (pIgR). Only polymeric IgA and IgM containing a small polypeptide called the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2004)Winter is energetically challenging for small herbivores because of greater energy requirements for thermogenesis at a time when little energy is available. We formulated a model predicting optimal wintering body size, ...

(Master thesis / Hovedoppgave, 2004)1. Sammendrag Toksikogenomikk forener metoder brukt i klassisk toksikologi og metoder fra molekylær biologi. Den nye disiplinen bruker transkripsjonal genprofilering som et ledd i risiko- vurdering for både nye og gamle ...
-
(Master thesis / Hovedoppgave, 2005)SAMMENDRAG Celler er kontinuerlig utsatt for påvirkninger som kan skade dets DNA. Dette inkluderer oksidative DNA-skader, som oppstår via normal oksidativ metabolisme, og fra forbindelser i miljøet. Slike DNA-skader kan ...
-
(Master thesis / Hovedoppgave, 2005)ABSTRACT Cell-based assays are useful and effective for biomonitoring and toxicity screening purposes, and there is a need for fast, routine and simple screening assays. An assay to detect the production of reactive oxygen ...

(Master thesis / Hovedoppgave, 2005)Abstract Juniperus procera is a long-lived quality timber species that is endangered in its entire African distribution and listed as lower risk near threatened (LR-nt) in IUCN Red Data List for Malawi. It is characterized ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2006)The polymeric Ig receptor (pIgR), also called membrane secretory component (SC), mediates epithelial transcytosis of polymeric immunoglobulins (pIgs). J Chain-containing polymeric IgA (pIgA) and pentameric IgM bind pIgR ...
