Primary Porcine Brain Endothelial Cells as In Vitro Model to Study Effects of Ultrasound and Microbubbles on Blood-Brain Barrier Function
(Journal article; Peer reviewed, 2017)Focused ultrasound in the presence of microbubbles transiently and reversibly opens the blood-brain barrier (BBB) in rodents and humans thereby providing a time window for increased drug delivery into brain tissue. To get ... -
Primary Treatment Effects for High-Grade Serous Ovarian Carcinoma Evaluated by Changes in Serum Metabolites and Lipoproteins
(Peer reviewed; Journal article, 2023)High-grade serous ovarian carcinoma (HGSOC) is the most common and deadliest ovarian cancer subtype. Despite advances in treatment, the overall prognosis remains poor. Regardless of efforts to develop biomarkers to predict ... -
Prior statin use and 90-day mortality in Gram-negative and Gram-positive bloodstream infection: a prospective observational study
(Journal article; Peer reviewed, 2014)n several studies on patients with bloodstream infection (BSI), prior use of statins has been associated with improved survival. Gram-positive and Gram-negative bacteria alert the innate immune system in different ways. ... -
A probabilistic function to model the relationship between quality of chest compressions and the physiological response for patients in cardiac arrest
(Peer reviewed; Journal article, 2020)Cardiopulmonary resuscitation quality (CPRQ) parameters can be derived from electric signals obtained during resuscitation. We propose to model a probabilistic relationship between CPRQ parameters and the physiological ... -
Probing tissue microstructure in tumors and surrounding brain: diffusion weighted MRI and beyond
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:230, Doctoral thesis, 2014)Med diffusjonsvektet MR (DMR) kan vi måle vanndiffusjon i biologisk vev, og på tross av at det underliggende mikromiljøet for diffusjon er komplekst sammensatt, har enkle tilnærmingsmodeller for det diffusjonsvektede ... -
The prognostic impact of depressive symptoms on all-cause mortality in individuals with abdominal aortic aneurysm and in the general population. A population-based prospective HUNT study in Norway
(Peer reviewed; Journal article, 2022)Background Abdominal aortic aneurysm (AAA) is a potentially life-threatening disease but the high mortality rate is linked to high age and comorbidity pattern. Depression is associated with increased mortality in the general ... -
Prognostic value of circulating microRNA-210 levels in patients with moderate to severe aortic stenosis
(Journal article; Peer reviewed, 2014)Background: Circulating micro-RNAs have been proposed as a novel class of cardiovascular (CV) biomarkers, but whether they meet analytical requirements and provide additional information to establish risk indices have ... -
Prognostic value of combined MTV and ADC derived from baseline FDG PET/MRI in aggressive non-Hodgkins lymphoma
(Peer reviewed; Journal article, 2022)Purpose The aim of this prospective study was to investigate the prognostic value of metabolic tumor volume (MTV) and apparent diffusion coefficient (ADC) from baseline FDG PET/MRI compared to established clinical risk ... -
Prognostic value of metabolic response in breast cancer patients receiving neoadjuvant chemotherapy
(Journal article; Peer reviewed, 2012)Background Today's clinical diagnostic tools are insufficient for giving accurate prognosis to breast cancer patients. The aim of our study was to examine the tumor metabolic changes in patients with locally advanced breast ... -
Program for terrestrisk naturovervåking - Overvåking av jordvann. Sluttrapport 2000
(Rapport fra skogforskningen;, Research report, 2001)I Program for Terrestrisk Naturovervåking (TOV) ble det samlet inn jordvann fra humussjiktet (5 cm), humusblandet mineraljord (15 cm) og mineraljord i 40 cm dybde på fire overvåkingsflater i 2000. Disse flatene ligger i ... -
A prospective observational study comparing two supraglottic airway devices in out-of-hospital cardiac arrest
(Journal article; Peer reviewed, 2021)Background: Airway management in patients with out of hospital cardiac arrest (OHCA) is important and several methods are used. The establishment of a supraglottic airway device (SAD) is a common technique used during OHCA. ... -
A prospective study of pulmonary outcomes and chest computed tomography in the first year after COVID-19
(Peer reviewed; Journal article, 2023)COVID-19 primarily affects the respiratory system. We aimed to evaluate how pulmonary outcomes develop after COVID-19 by assessing participants from the first pandemic wave prospectively 3 and 12 months following hospital ... -
Prostate-Specific Membrane Antigen PET/Magnetic Resonance Imaging for the Planning of Salvage Radiotherapy in Patients with Prostate Cancer with Biochemical Recurrence After Radical Prostatectomy
(Journal article; Peer reviewed, 2019)Prostate-specific membrane antigen (PSMA) PET/magnetic resonance (MR) imaging can help distinguish between patients with prostate cancer with locoregional recurrence and those with distant metastases, even at low ... -
