Cardiac Alarmins as Residual Risk Markers of Atherosclerosis under Hypolipidemic Therapy
Suica, Viorel I.; Uyy, Elena; Ivan, Luminita; Boteanu, Raluca M.; Cerveanu-Hogas, Aurel; Hansen, Rune; Antohe, Felicia (Peer reviewed; Journal article, 2022)Increased levels of low-density lipoproteins are the main risk factor in the initiation and progression of atherosclerosis. Although statin treatment can effectively lower these levels, there is still a residual risk of ... -

The ... -
Hepatic Alarmins and Mitochondrial Dysfunction under Residual Hyperlipidemic Stress Lead to Irreversible NAFLD
Ivan, Luminita; Uyy, Elena; Suica, Viorel; Boteanu, Raluca; Cerveanu-Hogas, Aurel; Hansen, Rune; Antohe, Felicia (Peer reviewed; Journal article, 2022)Background and Aims: Nonalcoholic fatty liver disease (NAFLD) includes a range of progressive disorders generated by excess lipid accumulation in the liver leading to hepatic steatosis and eventually fibrosis. We aimed to ... -
Intravascular Targets for Molecular Contrast-Enhanced Ultrasound Imaging
Moestue, Siver Andreas; Gribbestad, Ingrid S; Hansen, Rune (Journal article, 2012) -
A multi-pulse ultrasound technique for imaging of thick-shelled microbubbles demonstrated in vitro and in vivo
Berg, Sigrid; Eggen, Siv; Caidahl, Kenneth; Dähne, Lars; Hansen, Rune (Peer reviewed; Journal article, 2022)Contrast enhanced ultrasound is a powerful diagnostic tool and ultrasound contrast media are based on microbubbles (MBs). The use of MBs in drug delivery applications and molecular imaging is a relatively new field of ... -
Multimodal Phantom of Liver Tissue
Chmarra, Magdalena Karolina; Hansen, Rune; Mårvik, Ronald; Langø, Thomas (Journal article, 2013)Medical imaging plays an important role in patients' care and is continuously being used in managing health and disease. To obtain the maximum benefit from this rapidly developing technology, further research is needed. ... -
Nanoparticle-stabilized microbubbles for multimodal imaging and drug delivery
Mørch, Ýrr Asbjørg; Hansen, Rune; Berg, Sigrid; Åslund, Andreas; Glomm, Wilhelm; Eggen, Siv; Schmid, Ruth; Johnsen, Heidi; Kubowicz, Stephan; Snipstad, Sofie; Sulheim, Einar; Hak, Sjoerd; Singh, Gurvinder; McDonagh, Birgitte Hjelmeland; Blom, Hans; Davies, Ruth Catharina de Lange; Stenstad, Per Martin (Journal article; Peer reviewed, 2015)Microbubbles (MBs) are routinely used as contrast agents for ultrasound imaging. The use of ultrasound in combination with MBs has also attracted attention as a method to enhance drug delivery. We have developed a technology ... -
Regulated cell death joins in atherosclerotic plaque silent progression
Uyy, Elena; Suica, Viorel I.; Boteanu, Raluca M.; Cerveanu-Hogas, Aurel; Ivan, Luminita; Hansen, Rune; Antohe, Felicia (Peer reviewed; Journal article, 2022)Non-apoptotic regulated cell death (ferroptosis and necroptosis) leads to the release of damage-associated molecular patterns (DAMPs), which initiate and perpetuate a non-infectious inflammatory response. We hypothesize ... -
Sonopermeation Enhances Uptake and Therapeutic Effect of Free and Encapsulated Cabazitaxel
Snipstad, Sofie; Mørch, Ýrr; Sulheim, Einar; Åslund, Andreas; Pedersen, André; Hansen, Rune; Davies, Catharina de Lange; Berg, Sigrid (Peer reviewed; Journal article, 2021)Delivery of drugs and nanomedicines to tumors is often heterogeneous and insufficient and, thus, of limited efficacy. Microbubbles in combination with ultrasound have been found to improve delivery to tumors, enhancing ... -
