12. NMR Investigations of Peptide-Membrane Interactions, Modulation of Peptide-Lipid Interaction as a Switch in Signaling across the Lipid Bilayer
Abstract : The complexity of multi cellular organisms demands systems that facilitate communicationbetween cells. The neurons in our brains for instance are specialized in this cell-cellcommunication. READ MORE

13. Biophysical investigations of ribonucleotide reductase : Activation and inhibition mechanisms
Abstract : Ribonucleotide reductase (RNR) is the enzyme responsible for de novo synthesis of deoxyribonucleotides, needed for both synthesis and repair of cellular DNA. The RNRs known so far are divided into three distinct classes; I, II and III. The conventional class I enzyme is composed of two separate subunits. READ MORE

14. The Biophysics of Na+,K+-ATPase in neuronal health and disease
Abstract : Na+,K+-ATPase is one of the most important proteins in the mammalian cell. It creates sodium and potassium gradients which are fundamental for the membrane potential and sodium-dependent secondary active transport. READ MORE

15. Automating STED microscopy for functional and structural live-cell imaging
Abstract : Optical microscopy imaging methods are today invaluable tools for studies in life sciences as they allow visualization of biological systems, tissues, cells, and sub-cellular compartments from millimetres down to nanometres. The invention and development of nanoscopy in the past 20 years has pushed fluorescence microscopy down to the nanoscale, reaching beyond the natural diffraction limit of light that does not allow focusing of visible light below sizes of around 200 nm, and into the realm of what was previously only thought possible with electron microscopy.
