Methods: We measured inflammatory mediators, antibodies to the SARS-CoV-2 spike and nucleocapsid proteins, and spike peptide-induced release of interferon gamma in whole blood in 51 double-vaccinated individuals infected with Omicron, in 14 infected with Delta, and in 18 healthy controls. The median time points for the first and second samples were 7 and 14 days after symptom onset, respectively.
Findings: Infection with Omicron or Delta led to a rapid and similar increase in antibodies to the receptor-binding domain (RBD) of Omicron protein and spike peptide-induced interferon gamma in whole blood. Both the Omicron- and the Delta-infected patients had a mild and transient increase in inflammatory parameters.

Viridans gruppe streptokokker – inflammatorisk respons i en blodmodell
Broback, Bjørn Martin (Master thesis; Mastergradsoppgave, 2022-05-31)Bakgrunn: Viridans gruppe streptokokker (VGS) er en heterogen gruppe med bakterier som er sett på som opportunistiske bakterier. De har nå blitt en vanligere årsak til alvorlig sepsis hos nyfødte og immunsupprimerte barn. Formålet med denne studien er å sammenligne immunresponsen til en VGS bakterie (Streptococcus mitis) mot en gruppe B streptokokk (GBS) og Staphylococcus haemolyticus i en ex vivo ... -
Prognostic Impacts of Angiopoietins in NSCLC Tumor Cells and Stroma : VEGF-A Impact Is Strongly Associated with Ang-2
Andersen, Sigve; Dønnem, Tom; Al-Shibli, Khalid Ibrahim; Al-Saad, Samer; Stenvold, Helge; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)Angiopoietins and their receptor Tie-2 are, in concert with VEGF-A, key mediators in angiogenesis. This study evaluates the prognostic impact of all known human angiopoietins (Ang-1, Ang-2 and Ang-4) and their receptor Tie-2, as well as their relation to the prognostic expression of VEGF-A. 335 unselected stage I-IIIA NSCLC-patients were included and tissue samples of respective tumor cells and ... -
The Temporomandibular Joint in Juvenile Idiopathic Arthritis, focusing on Quality of Life, Oral Microbiome and Intervention
Frid, Paula (Doctoral thesis; Doktorgradsavhandling, 2020-10-02)The temporomandibular joint (TMJ) is commonly involved in juvenile idiopathic arthritis (JIA), and may lead to impaired mouth opening, pain and facial growth disturbances. Asymptomatic TMJ arthritis may be diagnosed late in the disease course, thus management is challenging. The overall objectives of this thesis were to provide new knowledge on quality of life (QoL), the oral microbiome and interventions ...
