    Abstract : In the first chapter we test if Purchasing Power Parity, PPP, is empirically valid and when that is not the case we test if productivity growth differences can account for the deviations from PPP by co-integration analysis. Interestingly, the results lend support in favour of PPP in several cases and when PPP is rejected GDP per capita growth rate differences seem to explain the long-run deviations from PPP. READ MORE

  7. 25. Insulin-like growth factor 1 receptor, novel functions and future possibilities

    Author : Ahmed Waraky; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Insulin like growth factor-1 receptor (IGF-1R) has been shown to be important for cancer cell growth and survival, and is often overexpressed in malignant and premalignant tissues. Ligand binding to IGF-1R induces transphosphorylation and activation of the receptor, leading to subsequent activation of the phosphatidyl inositol-3 kinase (PI3K), the mitogen-activated protein kinase (MAPK) and the 14-3-3 pathways.
