Bradykinin-Induced Shock Increase Exhaled Nitric Oxide, Complement Activation and Cytokine Production in Pigs
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-04)Bradykinin is an important mediator in blood pressure regulation, ischemic precondition and capillary leakage, allergy, anaphylaxis, inflammation, and nociception, at least partly via the generation of nitric oxide (NO). Macrophages are particularly abundant in the porcine lung circulation. Upon bradykinin binding macrophages release cytokines and endothelial ... -
Iohexol plasma clearance for measuring glomerular filtration rate in clinical practice and research: a review. Part 2: Why to measure glomerular filtration rate with iohexol?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-09)A reliable assessment of glomerular filtration rate (GFR) is of paramount importance in clinical practice as well as epidemiological and clinical research settings. It is recommended by Kidney Disease: Improving Global Outcomes guidelines in specific populations (anorectic, cirrhotic, obese, renal and non-renal transplant patients) where estimation equations are unreliable. Measured GFR is the ... -
Iohexol plasma clearance for measuring glomerular filtration rate in clinical practice and research: a review. Part 1: How to measure glomerular filtration rate with iohexol?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-23)While there is general agreement on the necessity tomeasure glomerular filtration rate (GFR) inmany clinical situations, there is less agreement on the bestmethod to achieve this purpose.As the gold standardmethod for GFR determination, urinary (or renal) clearance of inulin, fades into the background due to inconvenience and high cost, a diversity of filtrationmarkers and protocols compete to ... -
Associations between Common and Rare Exonic Genetic Variants and Serum Levels of 20 Cardiovascular-Related Proteins: The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-21)Background—Genetic variation can be used to study causal relationships between biomarkers and diseases. Here, we identify new common and rare genetic variants associated with cardiovascular-related protein levels (protein quantitative trait loci [pQTLs]). We functionally annotate these pQTLs, predict and experimentally confirm a novel molecular interaction, and determine which pQTLs are associated ... -
A retrospective comparison of ultrasound-assisted catheter-directed thrombolysis and catheter-directed thrombolysis alone for treatment of proximal deep vein thrombosis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016)Background: Recent studies have suggested that catheterdirected thrombolysis (CDT) reduces development of postthrombotic syndrome (PTS). Ultrasound-assisted CDT (USCDT) might enhance the efficiency of thrombolysis. We aimed to compare USCDT with CDT on efficacy, safety, development of PTS, and quality of life after longterm follow-up. <p>Methods: We describe a retrospective case series of 94 ... -

Lack of association between cluster headache and PER3 clock gene polymorphism
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-02-29)Background Cluster headache (CH) is regarded as a chronobiological disorder. The hypothalamic biological clock may thus be involved in the pathophysiology, but few studies have actually investigated this in CH patients. A variable number tandem repeat (VNTR) polymorphism of the PER3 clock gene has been associated to preferred daily rhythm (chronotype) in several studies. We aimed to study the ... -
Mesenchymal stromal cells from human umbilical cords display poor chondrogenic potential in scaffold-free three dimensional cultures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-27)Many researchers world over are currently investigating the suitability of stromal cells harvested from foetal tissues for allogeneic cell transplantation therapies or for tissue engineering purposes. In this study, we have investigated the chondrogenic potential of mesenchymal stromal cells (MSCs) isolated from whole sections of human umbilical cord or mixed cord (UCSCs-MC), and compared them with ... -

The assessment of serum-mediated phagocytosis of necrotic material by polymorphonuclear leukocytes to diagnose and predict the clinical features of systemic lupus erythematosus: An observational longitudinal study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-02-10)Background: Serum-mediated phagocytosis of antibody- and complement-opsonized necrotic cell material (NCM) by polymorphonuclear leukocytes can be quantified by using a flow cytometry–based assay. The phagocytosis of necrotic cell material (PNC) assay parallels the well-known lupus erythematosus cell test. In this study, we aimed to investigate the diagnostic accuracy of the assay and the relationship ... -
An examination of the language construct in NIMH's research domain criteria: Time for reconceptualization!
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-10)The National Institute of Mental Health’s Research Domain Criteria (RDoC) Initiative “calls for the development of new ways of classifying psychopathology based on dimensions of observable behavior.” As aresult of this ambitious initiative, language has been identifi d as an independent construct in the RDoC matrix. In this article, we frame language within an evolutionary and neuro- ... -

Assessing and Improving EHRs Data Quality through a Socio-technical Approach
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-21)The implementation of Electronic Health Records (EHRs) in developing countries is considered a means for improving data quality and high quality care. However, existing research, indicate that EHRs have recorded greater quantity of bad data instead of improving the quality of data. The reasons for this is not exactly clear. Accordingly, this paper takes a broader socio-technical approach to explore ... -
Concepts of ‘self’ in delusion resolution
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-04)The concept of ‘self’ has a pivotal role in psychotic symptoms (Conrad, 1958), but its utility in the treatment process has been limited. Since perceptions of ‘self’ – and of ‘others’ – change as symptoms evolve and resolve (Parnas andHandest, 2003), if appropriately assayed this concept provides a unique entry-point through which the congruity between delusions and illness can be examined. The ... -
The Association Between Adiponectin, Serum Uric Acid and Urinary Markers of Renal Damage in the General Population: Cross-Sectional Data from the Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-14)Background/Aims: Uric acid may cause renal damage, whereas adiponectin in some studies has been reported to have renoprotective properties. The renoprotective role of adiponectin under the influence of hyperuricemia has not been explored. We assessed the cross-sectional association between adiponectin, serum uric acid (SUA) and urinary biomarkers of glomerular and tubular damage (albumin-creatinine ... -
