  1. 21. Conformational and Dynamical Aspects of Conjugated Polymers and Oligomers of Interest for Photoluminescence

    Författare :Mette Grage; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; femtosecond spectroscopy; conformations; anisotropy; excitation transfer; oligothiophene radical cations; MEH-PPV; Conjugated polymers; polythiophene; resonance Raman spectroscopy.; Chemistry; Kemi; Physics; Fysik;

    Sammanfattning : Transient absorption laser spectroscopy and resonance Raman spectrscopy have been used to study conjugated polymers and oligomers. To extract more information the measurements have been compared to computer simulations and calculations. LÄS MER

  3. 22. Modeling environment effects on spectroscopic properties of biomarkers and catalytic mechanisms in enzymes

    Författare :Camilla Gustafsson; Patrick Norman; Daniel Escudero; KTH; []
    Nyckelord :Computational chemistry; spectroscopy; biocatalysis; water flow; biomarkers; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Sammanfattning : Arguably, humans are in need of both better diagnostic tools to prevent pro- gression of diseases as well as greener catalysts for synthesis of chemicals.Neurodegenerative diseases affecting neurons in the brain leads to demen- tias, where Alzheimer’s disease (AD) is the most prevalent.

  4. 23. Epigenetic and bioelectronic tools to study neural stem cells in health and disease

    Författare :Christina Neofytou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Brain development is a highly controlled, complex, and dynamic process. The mechanisms of its control need to accommodate the constantly changing contexts which, overtime, support the emergence of new neural structures and functions. LÄS MER

  5. 24. The Importance of Macrophages, Lipid Membranes and Seeding in Experimental AA Amyloidosis

    Författare :Aida Vahdat Shariatpanahi; Karin Öllinger; Katarzyna Lundmark; Gunilla Westermark; Elin Esbjörner Winters; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Amyloidosis is a group of protein misfolding diseases caused by tissue deposition of fibrillary protein aggregates termed amyloid. Amyloid A (AA) amyloidosis is a systemic form of amyloidosis that occurs as a complication of chronic inflammatory diseases, such as rheumatoid arthritis, familial Mediterranean fever and chronic infections, such as tuberculosis.

  7. 25. Tissue microbiology : an integrated approach for intravital studies of host-pathogen interactions

    Författare :Ferdinand Xiankeng Choong; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A bacteria infection in the living host is the summation of a myriad of interactions. Reductionistic and sacrificial experiment models cannot replicate this complexity. The Tissue Microbiology approach overcomes this by allowing the live host and pathogen to control all facets of the infection model. LÄS MER
