2. 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

4. Monopolar and Bipolar Membranes in Organic Bioelectronic Devices
Abstract : In the 1970s it was discovered that organic polymers, a class of materials otherwise best know as insulating plastics, could be made electronically conductive. As an alternative to silicon semiconductors, organic polymers offer many novel features, characteristics, and opportunities, such as producing electronics at low costs using printing techniques, using organic chemistry to tune optical and electronic properties, and mechanical flexibility.

5. Cell division in Escherichia coli
Abstract : The Gram-negative bacterium Escherichia coli is a model system to describe the biochemistry and cell biology of cell division in bacteria. This process can be divided into three major steps. The first step involves the replication of the DNA, followed by an elongation step in which the cells become twice as long. READ MORE
