The role of mitochondrial reactive oxygen species, NO and H2S in ischaemia/reperfusion injury and cardioprotection
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-08)Redox signalling in mitochondria plays an important role in myocardial ischaemia/reperfusion (I/R) injury and in cardioprotection. Reactive oxygen and nitrogen species (ROS/RNS) modify cellular structures and functions by means of covalent changes in proteins including among others S‐nitros(yl)ation by nitric oxide (NO) and its derivatives, and S‐sulphydration by hydrogen sulphide (H<sub>2</sub>S). ... -
The role of MMP-2 and MMP-14 in cell migration and invasion
(Master thesis; Mastergradsoppgave, 2014-02-03)Cancer is becoming a global epidemic in recent times and can affect different organs in the body and even more worrying is that they do not have a common cause. Several factors have been implicated in the onset and spread of cancers, one of which are the metalloproteinases (MMPs). The MMPs utilize the same strategy they employ in normal physiological processes in pathology, thus creating a dilemma ... -
The role of moderating variables on BOLD fMRI response during semantic verbal fluency and finger tapping in active and educated healthy seniors
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-05)Semantic verbal fluency is among the most employed tasks in cognitive aging research and substantial work is devoted to understanding the underlying mechanisms behind age-related differences at the neural and behavioral levels. The present investigation aimed to evaluate the role of moderating variables, such as age, sex, MMSE, and proxies of cognitive reserve (CR) on the hemodynamic response evoked ... -
Role of monocyte procoagulant functions in the pathophysiology of arterial and venous thrombosis
(Doctoral thesis; Doktorgradsavhandling, 2011-12-16)Monocytter, en klasse hvite blodlegemer i blodet, spiller en sentral rolle i kroppens immunforsvar og for blodets evne til å levre seg og danne en blodpropp. De kan ved stimulering, som ved sykelige tilstander, uttrykke vevsfaktor (TF) på celleoverflaten. TF er ansvarlig for å sette i gang blodproppmekanismen. En blodpropp kan dannes i kroppens samleårer (vener – kalles da dyp venøs trombose eller ... -
The role of NADPH oxidases in diabetic cardiomyopathy
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-25)Systemic changes during diabetes such as high glucose, dyslipidemia, hormonal changes and low grade inflammation, are believed to induce structural and functional changes in the cardiomyocyte associated with the development of diabetic cardiomyopathy. One of the hallmarks of the diabetic heart is increased oxidative stress. NADPH-oxidases (NOXs) are important ROS-producing enzymes in the cardiomyocyte ... -
The Role of Need for Cognition in the Association Between Work Demands and Home Outcomes
(Master thesis; Mastergradsoppgave, 2023-04-28)Kjærlighetsrelasjoner er en viktig del av våres liv og forskning viser til at kontekstuelle utfordringer (f.eks., arbeidsmengde), kan negativt påvirke slike relasjoner–et eksempel på jobb–til–liv konflikt. Arbeidet man utfører blir stadig mer komplekst og ansatte må utføre oppgaver som er både ukjente og utfordrende. Selv om slik kvalitativ arbeidsmengde er utbredt blant ansatte, vet vi lite om ... -

Role of Oestrogen α Receptors in Sociosexual Behaviour in Female Rats Housed in a Seminatural Environment
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-28)The present study investigated the role of oestrogen receptor (ER)α in the ventromedial nucleus of the hypothalamus (VMN), the preoptic area (POA), the medial amygdala (MePD) and the bed nucleus of stria terminalis (BNST) in sociosexual behaviour in female rats. This was conducted in two sets of experiments, with the VMN and POA investigated in the first set, and the MePD and BNST in the second set. ... -
The role of ovarian reserve markers in fertility and fertility treatment
(Doctoral thesis; Doktorgradsavhandling, 2021-05-14)Ovarian reserve is a key component influencing reproductive function and fertility. Serum anti-Mullerian hormone (AMH) and antral follicle count (AFC) are established quantitative markers of ovarian reserve. The overall aim of this thesis comprising four work packages was to study the role of AMH and AFC on different aspects of fertility and fertility treatment. Their specific objectives were: 1) To ... -

The Role of Plasma Extracellular Vesicles and Procoagulant Phospholipid Activity in Venous Thromboembolism
(Doctoral thesis; Doktorgradsavhandling, 2021-11-05)Venous thromboembolism (VTE) is the formation of a blood clot in, most commonly, the deep veins of the lower extremities and the pulmonary circulation. VTE is a prevalent disease associated with severe short- and long-term complications. Negatively charged procoagulant phospholipids (PPL), and phosphatidylserine (PS) in particular, are vital to efficient coagulation activation, and found expressed ... -
The Role of Preoperative Inflammatory Markers in Pancreatectomy: a Norwegian Nationwide Cohort Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-15)Background and purpose Preoperative infammatory markers, such as Glasgow prognostic score, modifed Glasgow prognostic score and C-reactive protein to albumin ratio, were shown to be associated with prognosis in patients undergoing pancreatectomy for cancer. However, little is known about their predictive role in a Western population.<p> <p>Methods The Norwegian National Registry for Gastrointestinal ... -

A role of Sp1 binding motifs in basal and large T-Antigen-induced promoter activities of human polyomavirus HPyV9 and its variant UF-1
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-14)Human polyomavirus 9 (HPyV9) was originally detected in the serum of a renal transplant patient. Seroepidemiological studies showed that ~20-50% of the human population have antibodies against this virus. HPyV9 has not yet been associated with any disease and little is known about the route of infection, transmission, host cell tropism, and genomic variability in circulating strains. Recently, the ... -

The role of steroid hormone receptors in prostate cancer. A study of estrogen- and progesterone receptors in adenocarcinoma of the prostate
(Doctoral thesis; Doktorgradsavhandling, 2018-06-15)Steroid hormones and their receptors are vital for numerous physiological processes in the human body, but also related to the development of several malignancies. One such receptor strongly associated with prostate cancer, is the androgen receptor. Other steroid hormone receptors are also implicated in prostate cancer, their role, however, remains to be defined. Using immunohistochemistry and tissue ... -
The Role of Stroke as a Trigger for Incident Venous Thromboembolism: Results from a Population-based Case-Crossover Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-22)Stroke is associated with a short-term increased risk of subsequent venous thromboembolism (VTE). It is unclear to what extent this association is mediated by strokerelated complications that are potential triggers for VTE, such as immobilization and infection. We aimed to investigate the role of acute stroke as a trigger for incident VTE while taking other concomitant VTE triggers into account. ... -
The Role of Surgery as a Trigger for Incident Venous Thromboembolism
(Master thesis; Mastergradsoppgave, 2020-08-30)Background: Venous thromboembolism (VTE) is a collective term for deep vein thrombosis and pulmonary embolism. Surgery is a major and well-established transient risk factor (i.e. trigger) for VTE in the general population. However, the impact of major surgery on the risk of VTE has not been thoroughly investigated when other concomitant VTE triggers are also taken into account. Aim: The aim of ... -
Role of the Complement System in the Pathogenesis of Venous Thromboembolism
(Doctoral thesis; Doktorgradsavhandling, 2019-04-02)Venous thromboembolism (VTE) is a common disease with serious short- and long-term complications. VTE is a collective term for deep vein thrombosis (DVT) and pulmonary embolism (PE) and is the third most common cardiovascular disease, causing significant morbidity and mortality. Despite preventive strategies, the incidence of VTE has been stable or increasing slightly during the last decades, affecting ...
