1. Food choice in fallow deer – experimental studies of selectivity
Abstract : In this thesis, I experimentally investigate feeding selectivity in fallow deer (Dama dama), with respect to plant secondary compounds, especially tannins, which can decrease the quality of foods. I found that fallow deer avoided foods with higher amounts of tannic acid and Quebracho tannin, even though the deer ate some high-tannin food. READ MORE

3. Cell death and signal transduction pathways in Alzheimer's disease : the role of presenilin 1
Abstract : Mutated presenilins (PSs) may cause familial Alzheimer's disease (FAD) by altering neuronal signal transduction pathways, by increasing AP production or by triggering a number of proapoptotic mechanisms. The present thesis explores mechanisms by which PSs regulate signal transduction and cell death with relevance to AD. READ MORE

5. ATP Dynamics in Pancreatic α- and β-cells
Abstract : Glucose metabolism in pancreatic α- and β-cells is believed to regulate secretion of glucagon and insulin, respectively. In β-cells, ATP links glucose metabolism to electrical activity and insulin secretion. READ MORE
