Are physical measures good indicators of image quality at low dose levels? A pilot study
(Chapter; Peer reviewed, 2016)Purpose: To evaluate if physical measures of noise predict image quality at high and low noise levels. Method: Twenty-four images were acquired on a DR system using a Pehamed DIGRAD phantom ... -
The Influence of CT Reconstruction Methods on the Accuracy of Monitoring Lung Nodule Diameters at Different Dose Levels
(Chapter; Peer reviewed; Chapter, 2016)Purpose: This study aims to investigate the effect of filtered back projection (FBP) and sinogram-affirmed iterative reconstruction (SAFIRE) on the accuracy of lung nodule diameter measurements at different dose ... -
Risk of breast cancer after false-positive results in mammographic screening
(Journal article; Peer reviewed, 2016)Women with false-positive results are commonly referred back to routine screening. Questions remain regarding their long-term outcome of breast cancer. We assessed the risk of screen-detected breast cancer in women with ... -
LIMT is a novel metastasis inhibiting lncRNA suppressed by EGF and downregulated in aggressive breast cancer
(Journal article; Peer reviewed, 2016)Long noncoding RNAs (lncRNAs) are emerging as regulators of gene expression in pathogenesis, including cancer. Recently, lncRNAs have been implicated in progression of specific subtypes of breast cancer. One aggressive, ... -
Discovery of miRNAs and Their Corresponding miRNA Genes in Atlantic Cod(Gadus morhua): Use of Stable miRNAs as Reference Genes Reveals Subgroups of miRNAs That Are Highly Expressed in Particular Organs
(Peer reviewed; Journal article; Journal article, 2016-04-29)Background Atlantic cod (Gadus morhua) is among the economically most important species in the northern Atlantic Ocean and a model species for studying development of the immune system in vertebrates. MicroRNAs (miRNAs) ... -
The Influence of Source-to-Image Distance on Effective Dose and Image Quality for Mobile Chest X-ray Imaging
(Chapter; Peer reviewed, 2017)Aim: To investigate the effect of source-to-image distance (SID) on effective dose and image quality at a fixed mAs. Furthermore, to determine whether effective dose varies as SID is varied after compensating mAs for ... -
Expression and function of the miR-143/145 cluster in vitro and in vivo in human breast cancer
(Journal article; Peer reviewed, 2017)MicroRNAs (miRNAs) are small non-coding RNAs that function as post-transcriptional regulators of gene expression and are dysregulated in cancer. Studies of miRNAs to explore their potential as diagnostic and prognostic ... -
Optimization of Codman® Hakim® adjustable valve radiography
(Journal article; Peer reviewed, 2017)Purpose Cerebrospinal fluid shunt valves is an important tool in hydrocephalus treatment. Adjustable valves, sensitive to MRI, are onerous. They need be controlled; in case of re-settings. The vendor give advices for ... -
Antimicrobial stewardship: a qualitative study of the development of national guidelines for antibiotic use in hospitals
(Journal article; Peer reviewed, 2017)Background As effective antibiotics are becoming a scarce resource, governmental regulation is needed to promote responsible use. Implementation of antibiotic stewardship and practice guidelines in health care facilities ... -
Use of a Commercially Available Microarray to CharacterizeAntibiotic-Resistant Clinical Isolates of Klebsiella pneumoniae
(Journal article; Peer reviewed, 2017)commercially available microarray (IDENTIBAC AMR-ve) for the detection of antibiotic resistance determinants was investigated for its potential to genotype 30 clinical isolates and two control strains of Klebsiella pneumoniae. ... -
Identification of differentially expressed Atlantic salmon miRNAs responding to salmonid alphavirus (SAV) infection
(Journal article; Peer reviewed, 2017)Background MicroRNAs (miRNAs) control multiple biological processes including the innate immune responses by negative post-transcriptional regulation of gene expression. As there were no studies on the role(s) of miRNAs ... -
Lower attendance rates in immigrant versus non-immigrant women in the Norwegian Breast Cancer Screening Programme
(Journal article; Peer reviewed, 2017)Objective The Norwegian Breast Cancer Screening Programme invites women aged 50-69 to biennial mammographic screening. Although 84% of invited women have attended at least once, attendance rates vary across the country. ... -
