1. One-click away from higher contrast : Improvements to peripheral clearance for same-day immunoPET in Alzheimer’s disease
Sammanfattning : The brain is a challenging target for antibody-based positron emission tomography (immunoPET) to image amyloid-beta (Aβ). Antibodies detect pathology with high sensitivity, but due to their size and biological half-life, they cause a high background radiation, if radiolabelled. LÄS MER
2. Preclinical PET imaging of Alzheimer's disease progression
Sammanfattning : Amyloid PET imaging with [11C]PIB enabled detection of Aβ for the first time in vivo. However, [11C]PIB is a small molecule that binds only the insoluble Aβ plaque. Rather, the soluble Aβ aggregates are considered the cause of Alzheimer’s disease (AD). LÄS MER
3. Genetic code expansion in neurons for studying pathogenic mechanisms of Alzheimer disease
Sammanfattning : Every three seconds a new patient is diagnosed with Alzheimer disease (AD). The primary risk factor for this irreversible, progressive brain disorder is old age. It is a growing health concern, not only for the patients, but also for their relatives and society, because the number of affected people is expected to double every 20 years. LÄS MER
4. Quantum chemical calculations of non-linear optical absorption
Sammanfattning : This thesis represents a quantum chemical treatise ofvarious types of interactions between radiation and molecularsystems, with special emphasis on the nonlinear opticalprocesses of Multi-Photon Absorption and Excited StateAbsorption. Excitation energies, transition dipole moments,two-photon and three-photon tensor elements have beencalculated from different approaches; density functional theoryandab-initiotheory, employing different orders ofcorrelation treatment with the purpose to provide accuratevalues as well as evaluate the quality of the lower ordermethods.
