The effect of electroconvulsive therapy (ECT) on serum tryptophan metabolites
Aarsland, Tore Ivar Malmei; Leskauskaite, Ieva; Midttun, Øivind; Ulvik, Arve; Ueland, Per Magne; Oltedal, Leif; Erchinger, Vera Jane; Ødegaard, Ketil Joachim; Haavik, Jan; Kessler, Ute (Peer reviewed; Journal article, 2019-05-31)Background: Prior studies suggest that activation of the tryptophan catabolism via the kynurenine pathway by proinflammatory cytokines may be involved in the pathophysiology of depression. Electroconvulsive therapy (ECT) ... -

Converging evidence suggests that electroconvulsive ... -
Feasibility of deep learning-based tumor segmentation for target delineation and response assessment in grade-4 glioma using multi-parametric MRI
Hannisdal, Marianne Hjellvik; Goplen, Dorota; Alam, Saruar; Haász, Judit; Oltedal, Leif; Rahman, Mohummad Aminur; Rygh, Cecilie Brekke; Lie, Stein Atle; Lundervold, Arvid; Enger, Martha (Journal article; Peer reviewed, 2023)Background Tumor burden assessment is essential for radiation therapy (RT), treatment response evaluation, and clinical decision-making. However, manual tumor delineation remains laborious and challenging due to ... -
Sequential bortezomib and temozolomide treatment promotes immunological responses in glioblastoma patients with positive clinical outcomes: A phase 1B study
