Repeatability in a multiphase pipe flow case study
Autor: Christian Brekken, Leif Rune Hellevik, Ingelin Steinsland, Paul Roger Leinan, Andreas Strand
Publikováno v: International Journal of Multiphase Flow
A high degree of repeatability is most often an underlying assumption for research and development based on multiphase flow experiments. In this paper repeatability in multiphase flow experiments are studied through an experimental campaign with 28 r

Loss or mislocalization of aquaporin-4 affects diffusion properties and intermediary metabolism in gray matter of mice
Autor: Christian Brekken, Olav Haraldseth, Ole Petter Ottersen, Ursula Sonnewald, Anna E. Thoren, Erlend A. Nagelhus, Tina Pavlin, Asta Håberg, Elvar M. Eyjolfsson
Publikováno v: Neurochemical Research
The first aim of this study was to determine how complete or perivascular loss of aquaporin-4 (AQP4) water channels affects membrane permeability for water in the mouse brain grey matter in the steady state. Time-dependent diffusion magnetic resonanc

Mn-alginate gels as a novel system for controlled release of Mn2+in manganese-enhanced MRI
Autor: Christian Brekken, Ioanna Sandvig, Yrr A. Mørch, Øystein Olsen, Olav Haraldseth, Marte Thuen, Ivan Donati, Gudmund Skjåk-Bræk
Publikováno v: Contrast Media & Molecular Imaging. 7:265-275
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 challenge of achieving optimal

In vivo MRI of olfactory ensheathing cell grafts and regenerating axons in transplant mediated repair of the adult rat optic nerve
Autor: Martin Berry, Ioanna Sandvig, Øystein Olsen, Susan C. Barnett, Axel Sandvig, Olav Haraldseth, Kåre E. Tvedt, Thomas C. P. Sardella, Linh Hoang, Christian Brekken, Marte Thuen
Publikováno v: NMR in Biomedicine. 25:620-631
The purpose of the present study was to use magnetic resonance imaging (MRI) as a tool for monitoring transplant-mediated repair of the adult rat visual pathway. We labelled rat olfactory ensheathing cells (OECs) using micron-sized particles of iron
