16. Bacterial virulence and adaptation mediated by two-component system signalling
Abstract : One of the most fundamental ways of signal perception and propagation is mediated by the bacterial two-component system (TCS). These types of systems mediate bacterial adaptation that may cause disease in a host due to expression of virulence factors. READ MORE

17. Control of bioluminescence. Operating the light switch in photophores from marine animals
Abstract : Physiologically controlled photocytes, capable of producing bioluminescence, are a common feature in the ocean among animals ranging from cnidarians to fish. The aim of this thesis was to study and compare the nature of this control, in both distantly and closely related species from the groups Teleostei Crustacea, and Cnidaria. READ MORE

18. Thin-fibre signalling in humans: Cortical processing of sensory afference and autonomic efference
Abstract : Thin nerve fibres innervate the entire human body and mediate sensations such as pain, temperature and visceral sensory input. Moreover, a special class of unmyelinated afferents responsive to light touch has recently been found in humans: C-tactile (CT) fibres. READ MORE

19. Protein phosphorylation and proteolysis - regulation and adaptive responses in photosynthesis
Abstract : Just as all other organisms, plants adapt to various environmental conditions. This work focuses on the role of chloroplast light harvesting complex II, LHCII, in adaptation of photosynthesis to changed light conditions. READ MORE

20. Towards quantitative single cell analysis using optical tweezers and microfluidics
Abstract : Experiments on single cells have the potential to uncover information that would not be possible to obtain with traditional biological techniques, which only reflect the average behavior of a population of cells. In the averaging process, information regarding heterogeneity and cellular dynamics, that may give rise to a nondeterministic behavior at the population level, is lost. READ MORE
