B cell receptor ligation induces display of V-region peptides on MHC class II molecules to T cells
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-03)The B cell receptors (BCRs) for antigen express variable (V) regions that are enormously diverse, thus serving as markers on individual B cells. V region-derived idiotypic (Id) peptides can be displayed as pId:MHCII complexes on B cells for recognition by CD4<sup>+</sup> T cells. It is not known if naive B cells spontaneously display pId:MHCII in vivo or if BCR ligation is required for expression, ... -
B Cell Tolerance to Deiminated Histones in BALB/c, C57BL/6, and Autoimmune-Prone Mouse Strains
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-30)Deimination, a posttranslational modification of arginine to citrulline carried out by peptidylarginine deiminases, may compromise tolerance of self-antigens. Patients with connective tissue autoimmunity, particularly rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), or Felty’s syndrome, present with autoantibodies to deiminated histones (dH), which thus form a category of antibodies ... -
B Vitamins and Hip Fracture: Secondary Analyses and Extended Follow-Up of Two Large Randomized Controlled Trials
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-28)Elevated plasma homocysteine levels are associated with increased risk of fractures in observational studies. However, it is unsettled whether homocysteine-lowering treatment affects fracture risk. The aim of this study was to investigate the effect of an intervention with B vitamins on the risk of hip fracture in a secondary analysis of combined data from two large randomized controlled trials ... -
B-1 plasma cells require non-cognate CD4 T cell help to generate a unique repertoire of natural IgM
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023)Evolutionarily conserved, “natural” (n)IgM is broadly reactive to both self and foreign antigens. Its selective deficiency leads to increases in autoimmune diseases and infections. In mice, nIgM is secreted independent of microbial exposure to bone marrow (BM) and spleen B-1 cell–derived plasma cells (B-1PC), generating the majority of nIgM, or by B-1 cells that remain non-terminally differentiated ... -
B12 and F430 models: Metal- versus ligand-centered redox in cobalt and nickel tetradehydrocorrin derivatives
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-23)DFT calculations with the well-tested OLYP and B3LYP* exchange-correlation functionals (along with D3 dispersion corrections and all-electron ZORA STO-TZ2P basis sets) and careful use of group theory have led to significant insights into the question of metal- versus ligand-centered redox in Co and Ni B,C-tetradehydrocorrin complexes. For the cationic complexes, both metals occur in their low-spin ... -
B4GALT family mediates the multidrug resistance of human leukemia cells by regulating the hedgehog pathway and the expression of p-glycoprotein and multidrug resistance-associated protein 1
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)b-1, 4-Galactosyltransferase gene (B4GALT) family consists of seven members, which encode corresponding enzymes known as type II membrane-bound glycoproteins. These enzymes catalyze the biosynthesis of different glycoconjugates and saccharide structures, and have been recognized to be involved in various diseases. In this study, we sought to determine the expressional profiles of B4GALT family ... -
Babymoon Tourism: Co-Creating Well-Being for Traveling Mothers
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-03)This article aims to provide insight into how babymoon tourism can contribute to well-being by using a multimethod approach, combining autoethnography and netnography. The findings show that mothers-to-be experience well-being derived from co-creation and meaning. Participation in activities and everyday-like events at the destination can lead to happiness and improved quality of life. Self-development, ... -
Bachelor studies for nurses organised in rural contexts - a tool for improving health care services in circumpolar region?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012-03-30)<p><i>Objectives:</i> This article is based on a pilot study of Finnmark University College's off-campus bachelor programme (BA) for nurses, organised in rural areas. The objectives were to explore whether these courses had contributed to reduced vacancies; whether the learning outcome of the off-campus courses was the same as the on-campus programme, and how the education had influenced the nurses’ ... -
Bacillus anthracis gamma phage lysis among soil bacteria: An update on test specificity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-16)Background: <br> Bacillus anthracis, which causes anthrax in humans and animals, is enzootic in parts of the U.S. state of Texas where cases are typically reported in animals annually. The gamma phage lysis assay is a common diagnostic method for identifcation of B. anthracis and is based on the bacterium’s susceptibility to lysis. This test has been shown to be 97% specifc for B. anthracis, as ... -

Back to the Future? Revisiting Military Confidence-Building in Europe
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018)The last few years have seen a paradigm shift in European security. NATO and Russia are once again stepping up their military activities and building their military arsenals, as deep mistrust and the fear of unintended military escalation seem to have returned. Over the last few decades, such concerns could be mitigated by an interlocking web of arms control and confidence- and security-building ... -

BacklinkDB: A Purpose-Built Backlink Database Management System
(Master thesis; Mastergradsoppgave, 2023-02-15)In order to compile a list of all the backlinks for a given webpage, we need knowledge about all the outgoing links on the web. Traversing the web and storing all the backlink data in a database allows us to efficiently retrieve the list of backlinks for a web page on demand. However, the web consists of billions of backlinks which translates to terabytes of data. As the web is continuously evolving, ... -
Backpropagation Neural Networks for Facial Recognition
(Master thesis; Mastergradsoppgave, 1991-12)A survey was conducted testing the aptitude of neural networks to recognize human faces. The motivation for this a study is the possibility of designing automatic security systems. Pictures of 511 subjects were collected. The pictures captured both profiles and many natural expressions of the subject. Some of the subjects were wearing glasses, sunglasses or hats in some of the pictures. The images ... -
The Backward-Bending Supply Curve in Fisheries-Revisited
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)This study discusses and estimates the backward-bending supply curve, using data for three years over a six-year time span from the inshore purse seine fishery in Khanh Hoa province, Vietnam. Four different models are developed for estimation based on fisheries data, in the absence of stock survey data. The estimated maximum sustainable yield for the anchovy in south-central Vietnam ranges from ... -
