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 ... -
Early metabolite changes after melatonin treatment in neonatal rats with hypoxic-ischemic brain injury studied by in-vivo 1H MR spectroscopy
Berger, Hester Rijkje; Nyman, Axel Karl Gottfrid; Morken, Tora Sund; Vettukattil, Muhammad Riyas; Brubakk, Ann-Mari; Widerøe, Marius (Journal article; Peer reviewed, 2017)Melatonin is a promising neuroprotective agent after perinatal hypoxic-ischemic (HI) brain injury. We used in-vivo 1H magnetic resonance spectroscopy to investigate effects of melatonin treatment on brain metabolism after ... -
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, ... -
Melatonin treatment for neonatal hypoxic ischemic brain injury: Translational barriers and how to break them
Nyman, Axel Karl Gottfrid (Doctoral theses at NTNU;2021:295, Doctoral thesis, 2021)Norsk sammendrag Hjerneskade i nyfødte (neonatal encefalopati, NE) er en vanlig lidelse med alvorlige konsekvenser for pasientene, deres familier og samfunnet. Den vanligste identifiserbare årsaken til NE er mangel på ... -
Transient effect of melatonin treatment after neonatal hypoxic-ischemic brain injury in rats
Berger, Hester Rijkje; Nyman, Axel Karl Gottfrid; Morken, Tora Sund; Widerøe, Marius (Journal article; Peer reviewed, 2019)Melatonin has potential neuroprotective capabilities after neonatal hypoxia-ischemia (HI), but long-term effects have not been investigated. We hypothesized that melatonin treatment directly after HI could protect against ...
