  2. 21. MRI Contrast Enhancement using Gd2O3 Nanoparticles

    Author : Anna Klasson; Maria Engström; Linköpings universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; nanoparticles; gadolinium oxide; magnetic resonance imaging; contrast agent; Medicine; Medicin;

    Abstract : There is an increasing interest for nanomaterials in biomedical applications and in this work, nanoparticles of gadolinium oxide (Gd2O3) have been investigated as a novel contrast agent for Magnetic Resonance Imaging (MRI). Relaxation properties have been studied in aqueous solutions as well as in cell culture medium and the nanoparticles have been explored as cell labeling agents. READ MORE

  4. 22. Evaluation of Repositioning in Pressure Ulcer Prevention

    Author : Ulrika Källman; Margareta Lindgren; Anna-Christina Ek; Maria Engström; Ingalill Rahm-Hallberg; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Introduction: To reduce the risk for pressure ulcers, repositioning of immobile patients is an important standard nursing practice. However, knowledge on how this preventive intervention is carried out among elderly immobile patients is limited and to what extent patients perform minor movements between nursing staff-induced repositionings is largely unknown, but these movements might have implications for the repositioning intervention.

  6. 24. Mechanistic modelling - a BOLD response to the fMRI information loss problem

    Author : Karin Lundengård; Maria Engström; Gunnar Cedersund; Fredrik Elinder; Susanna Walter; Kâmil Uludağ; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Functional Magnetic Resonance Imaging (fMRI) is a common technique for imaging brain activity in humans. However, the fMRI signal stems from local changes in oxygen level rather than from neuronal excitation. READ MORE

  7. 25. On electroconvulsive therapy in depression : Clinical, cognitive and neurobiological aspects
