  1. 11. Studies of Acute Rejection Using Contrast Agents and Magnetic Resonance Imaging

    Författare :Eva Penno; Håkan Ahlström; Cecilia Johnsson; Lars Johansson; Peter Leander; Uppsala universitet; []
    Nyckelord :Radiology; Magnetic resonance imaging; contrast agents; organ transplantation; acute rejection; Radiologisk forskning;

    Sammanfattning : Solid organ transplantation is today an established form of treatment for end-stage organ disease. Monitoring of graft function and pharmacological therapy constitutes a maze of clinical observations and histological evaluations of biopsy specimens; with the biopsy results playing a decisive role.

  3. 12. Static and Dynamic Correlation Effects in Atoms

    Författare :Nils-Erik Dahlen; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic and optical properties; electrical; Condensed matter:electronic structure; relaxation; magnetic resonance; supraconductors; spectroscopy; Kondenserade materiens egenskaper:elektronstruktur; Atom- och molekylärfysik; Atomic and molecular physics; spektroskopi; magnetisk resonans; egenskaper elektriska; supraledare; magnetiska och optiska ; variational energies; double ionization; Electron correlation; laser-atom interaction; Fysicumarkivet A:2002:Dahlen; conserving approximations; Green s functions; GW-approximation;

    Sammanfattning : The thesis considers the effects of electron correlation by studying the two opposite limits of atoms in the ground state and atoms in strong laser pulses. Computational methods and theoretical approaches differ significantly due to the different physical processes that are studied in these two cases. LÄS MER

  4. 13. Development and evaluation of analytical techniques for antibodies and antibody-drug conjugates : From verification of conjugation to stability testing

    Författare :Malin Källsten; Jonas Bergquist; Fredrik Lehmann; Sara Lind; Lucia Kovac; Alain Beck; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antibody-drug conjugates; drug-to-antibody ratio; monoclonal antibody; mass spectrometry; hydrophobic interaction chromatography; sample preparation; aggregation; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Sammanfattning : Antibody-drug conjugates (ADCs) are becoming increasingly important in oncology. ADCs are inherently heterogeneous analytes. For a successful drug candidate to go through to the clinic, extensive characterization and evaluation of the constructs are necessary. LÄS MER

  5. 14. Testing spatial independence using a separable covariance matrix

    Författare :Martin Ohlson; Dietrich von Rosen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : Spatio-temporal processes like multivariate time series and stochastic processes occur in many applications, for example the observations from functional magnetic resonance imaging (fMRl) or positron emission tomography (PET). It is interesting to test independence between k sets of the variables, that is testing spatial independence. LÄS MER

  7. 15. Magnetic Resonance Imaging in Parkinsons's disease and related disoders

    Författare :Yulia Surova; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mr Imaging; DTI; Parkinson s disease; Progressive supranuclear palsy; Multiple system atrophy;

    Sammanfattning : Objectives: To identify diagnostic and prognostic biomarkers in the cerebral white (WM) and the deep grey matter (GM) in patients with Parkinson’s disease (PD) and atypical parkinsonian syndromes (APS) using magnetic resonance imaging (MRI). Methods: Patients with a clinical diagnosis of PD, multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) were included in the study. LÄS MER
