(Journal article, 2012-01-30)Objective: To quantify the separate contributions of menopausal hormone treatment and mammography screening activities on trends in incidence of invasive breast cancer between 1987 and 2008. Design: Population study ... -
Selective serotonin reuptake inhibitors during pregnancy and risk of persistent pulmonary hypertension in the newborn: population based cohort study from the five Nordic countries
(Journal article, 2012-01-12)Objective: To assess whether maternal use of selective serotonin reuptake inhibitors (SSRIs) increases the risk of persistent pulmonary hypertension in the newborn, and whether such an effect might differ between specific ... -
Increased risk of atrial fibrillation among elderly Norwegian men with a history of long-term endurance sport practice
(Journal article; Peer reviewed, 2014)Atrial fibrillation (AF) is the most common cardiac arrhythmia. The prevalence increases with increasing age. In middle-aged men, endurance sport practice is associated with increased risk of AF but there are few studies ... -
Winters are changing: snow effects on Arctic and alpine tundra ecosystems
(Journal article; Peer reviewed, 2022)Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation determines ground temperature, light conditions and moisture availability during winter. It also affects the growing season’s start and ... -
Sperm counts and endocrinological markers of spermatogenesis in long-term survivors of testicular cancer
(Journal article; Peer reviewed, 2012)Background: The objective of this study was to assess markers of spermatogenesis in long-term survivors of testicular cancer (TC) according to treatment, and to explore correlations between the markers and associations ... -
Vinorelbine and gemcitabine vs vinorelbine and carboplatin as first-line treatment of advanced NSCLC. A phase III randomised controlled trial by the Norwegian Lung Cancer Study Group
(Journal article; Peer reviewed, 2012)Background: Platinum-based doublet chemotherapy is the standard first-line treatment for advanced non-small cell lung cancer (NSCLC), but earlier studies have suggested that non-platinum combinations are equally effective ... -

Trade, Traders, and Religion in Gateway-Cities of the Roman East
(Journal article; Peer reviewed, 2021)Long distance merchants occupied socially liminal positions in pre-modern societies, operating across in-groups that were mostly defined by birth. This created a double need for social cohesion within the merchant collective ... -
Relative Spatial Positions of Tryptophan and Cationic Residues in Helical Membrane-active Peptides Determine Their Cytotoxicity
(Journal article; Peer reviewed, 2012)The cytotoxic activity of 10 analogs of the idealized amphipathic helical 21-mer peptide (KAAKKAA)3, where three of the Ala residues at different positions have been replaced with Trp residues, has been investigated. The ... -
