I den epidemiologiske delen har vi brukt data fra den fjerde og den femte Tromsø undersøkelsen. Vi fant at kroppsmasseindeks (KMI) var nært knyttet til røykestatus og at personer som røkte 5–10 sigaretter per dag hadde lavest KMI. Vi fant også at personer med høyt nivå av parathyroideahormon (PTH, er sentralt hormon i kalkstoffskiftet) hadde lavere beintetthet og større fettmasse enn personer med normalt nivå av PTH. Disse sammenhengene mellom PTH, KMI og bentetthet ble kun funnet hos ikke-røykere. I intervensjonsstudien ble to ulike doser av D vitamin (20.000 IU og 40.000 IU per uke) sammenlignet med placebo (narremedisin) i en gruppe på 445 overvektige personer der hovedendemålet var vektreduksjon etter ett år. Ved studiens slutt var det ingen forskjell i vekt mellom de tre gruppene og vi finner det lite sannsynlig at tilskudd av D vitamin er av betydning for vektreduksjon hos ellers friske overvektige personer.

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 ...
