Brain Development after Neonatal Intermittent Hyperoxia-Hypoxia in the Rat Studied by Longitudinal MRI and Immunohistochemistry
Morken, Tora Sund; Nyman, Axel Karl Gottfrid; Sandvig, Ioanna; Torp, Sverre Helge; Skranes, Jon Sverre; Goa, Pål Erik; Brubakk, Ann-Mari; Widerøe, Marius (Journal article; Peer reviewed, 2013)Background: Neonatal intermittent hyperoxia-hypoxia (IHH) is involved in the pathogenesis of retinopathy of prematurity. Whether similar oxygen fluctuations will create pathological changes in the grey and white matter ... -
Effects of neural stem cell and olfactory ensheathing cell co-transplants on tissue remodelling after transient focal cerebral ischemia in the adult rat
Augestad, Ingrid Lovise; Nyman, Axel Karl Gottfrid; Costa, Alex Ignatius; Barnett, Susan Carol; Sandvig, Axel; Håberg, Asta; Sandvig, Ioanna (Journal article; Peer reviewed, 2017)Effective transplant-mediated repair of ischemic brain lesions entails extensive tissue remodeling, especially in the ischemic core. Neural stem cells (NSCs) are promising reparative candidates for stroke induced lesions, ... -
L-DOPA-Coated Manganese Oxide Nanoparticles as Dual MRI Contrast Agents and Drug-Delivery Vehicles
McDonagh, Birgitte Hjelmeland; Singh, Gurvinder; Hak, Sjoerd; Bandyopadhyay, Sulalit; Augestad, Ingrid Lovise; Peddis, Davide; Sandvig, Ioanna; Sandvig, Axel; Glomm, Wilhelm (Journal article; Peer reviewed, 2016)Manganese oxide nanoparticles (MONPs) are capable of time-dependent magnetic resonance imaging contrast switching as well as releasing a surface-bound drug. MONPs give T2/T2* contrast, but dissolve and release T1-active ... -
Labelling of olfactory ensheathing cells with micron-sized particles of iron oxide and detection by MRI
Sandvig, Ioanna; Hoang, Linh; Sardella, Thomas CP; Barnett, SC; Brekken, Christian; Tvedt, Kåre; Berry, Martin; Haraldseth, Olav; Sandvig, Axel; Thuen, Marte (Journal article; Peer reviewed, 2012)A crucial issue in transplant‐mediated repair of the damaged central nervous system (CNS) is serial non‐invasive imaging of the transplanted cells, which has led to interest in the application of magnetic resonance imaging ... -
Mn-alginate gels as a novel system for controlled release of Mn2+ in manganese-enhanced MRI
Mørch, Yrr Asbjørg; Sandvig, Ioanna; Olsen, Øystein; Donati, Ivan; Thuen, Marte; Skjåk-Bræk, Gudmund; Haraldseth, Olav; Brekken, Christian (Journal article; Peer reviewed, 2012)The aim of the present study was to test alginate gels of different compositions as a system for controlled release of manganese ions (Mn2+) for application in manganese‐enhanced MRI (MEMRI), in order to circumvent the ... -
Synthesis and in vitro cellular interactions of superparamagnetic iron nanoparticles with a crystalline gold shell
Bandyopadhyay, Sulalit; Singh, Gurvinder; Sandvig, Ioanna; Sandvig, Axel; Mathieu, Roland; Kumar, P Anil; Glomm, Wilhelm (Journal article; Peer reviewed, 2014)Fe@Au core–shell nanoparticles (NPs) exhibit multiple functionalities enabling their effective use in applications such as medical imaging and drug delivery. In this work, a novel synthetic method was developed and optimized ... -
The role of olfactory ensheathing cells, MRI, and biomaterials in transplant-mediated CNS repair
Sandvig, Ioanna (Doktoravhandlinger ved NTNU, 1503-8181; 2011:255, Doctoral thesis, 2011)Bruk av olfaktoriske ensheathing celler, MRI og biomaterialer i transplantasjonsmediert reparasjon av CNS skader Den beskrevne studien har brukt en interdisiplinær tilnærming for å evaluere transplantasjons mediert CNS ...
