Ultrafast laser techniques are becoming indispensable in many diverse scientific disciplines. Within the Australian scientific community, there is a great need for enhanced access to sophisticated ultrafast laser instrumentation. The expansion to the femtosecond laser facility through the addition of state-of-the-art laser devices, will enable novel laser spectroscopy measurements and advanced optical microscopy techniques to be applied to investigations of advanced materials and biological systems. Access to such instrumentation is crucial to fields including photoluminescent conductive polymers, nanoparticles, engineered supramolecules for artificial photosynthetic systems, and photoactivated therapy and drug delivery/release technology.Read moreRead less

Characterisation of two-pore domain potassium channels: structure-function studies of the M1-P1 loops of TASK channels. TWIK-related Acid Sensitive K+ (TASK) channels are members of the novel class of two-pore domain potassium channel family. They are potently inhibited by local anaesthetics and have been implicated as having important roles in many pathophysiological conditions such as heart arrythmias, stroke, epilepsy, breast and other cancers. The in depth structural and functional character ....Characterisation of two-pore domain potassium channels: structure-function studies of the M1-P1 loops of TASK channels. TWIK-related Acid Sensitive K+ (TASK) channels are members of the novel class of two-pore domain potassium channel family. They are potently inhibited by local anaesthetics and have been implicated as having important roles in many pathophysiological conditions such as heart arrythmias, stroke, epilepsy, breast and other cancers. The in depth structural and functional characterisation of this class of potassium channels is of great importance as they are interesting targets for new therapeutic developments. Advancement of knowledge in the structure and function of these channels will underpin drug targeting that will aid preventative healthcare, allowing Australians to age well and age productively.Read moreRead less
Parametric Brain Imaging via Modeling and Analysis of Electroencephalographic Signals. Parameters of brain function and physiology will be spatially imaged with high time resolution via their effects on electroencephalographic (EEG) signals, a form of imaging that is impossible with existing methods. This will be achieved by improving existing physiologically-based models of the generation of EEGs and developing analysis tools based on fitting of model predictions to multielectrode EEG data.

This will be achieved by improving existing physiologically-based models of the generation of EEGs and developing analysis tools based on fitting of model predictions to multielectrode EEG data. The results will be used to probe spatiotemporal features of EEGs in normal subjects to explore the underlying fundamental mechanisms and to infer novel parameter variations of practical relevance.Read moreRead less
Electro-active and migratory peptides in lipid bilayers: NMR and biophysical studies. All living things are characterized by the separation of inner space from the surrounding medium by a self-assembling membrane. Selective entry and exit of water, ions and solutes is a defining feature of each type of cell. Some proteins sense the voltage difference across the cell membrane and open or close in response to voltage changes. Others, like bacterial toxins assemble in the membrane as pores, while o ....Electro-active and migratory peptides in lipid bilayers: NMR and biophysical studies. All living things are characterized by the separation of inner space from the surrounding medium by a self-assembling membrane. Selective entry and exit of water, ions and solutes is a defining feature of each type of cell. Some proteins sense the voltage difference across the cell membrane and open or close in response to voltage changes. Others, like bacterial toxins assemble in the membrane as pores, while other peptides migrate across the membrane piggy-backing their peptide cargo. The aim is to understand the molecular mechanisms in examples of these membrane-active peptides and proteins with a view to enabling rational intervention into their operation in situ in normal and disease states.Read moreRead less
NMR studies of membrane proteins and peptides in novel amphiphilic mesophases. Membrane proteins are the next frontier in structural biology. Our goal is the structural and mechanistic characterization of the proteins and peptides from platypus venom and a cardiac potassium ion channel, HERG, that has a particular role in the suppression of cardiac arrhythmias. To do this we will refine and develop methods using amphiphilic mesophases and micelles and state-of-the-art NMR spectroscopy.

To do this we will refine and develop methods using amphiphilic mesophases and micelles and state-of-the-art NMR spectroscopy. Electrophysiological analysis of ion channels and interactions with toxins will relate NMR structures to function. The NMR methodologies we develop will have broad applicability to membrane proteins in general.

The research performed at such a facility is exceedingly diverse, and often the underpinning technology is the only point of contact for users. A vibrant and productive facility requires a transparent interface between the scientist and the technology. This Network will set up the communication channels within the user base, and between the users and the facility development program.Read moreRead less
Nuclear magnetic resonance (NMR) studies of complex cellular responses: isotopomer sub-spaces, 'lost' ATP and 'tunable' anisotropy. Red blood cells (RBCs) transport oxygen around the body but they have other roles that are mediated by complex interconnecting metabolic pathways that generate myriad metabolites including ATP. A longstanding conundrum is the inability to account for ~60% of ATP turnover in human RBCs. Processes that may consume this 'lost' ATP, include autonomous motion of the cel ....Nuclear magnetic resonance (NMR) studies of complex cellular responses: isotopomer sub-spaces, 'lost' ATP and 'tunable' anisotropy. Red blood cells (RBCs) transport oxygen around the body but they have other roles that are mediated by complex interconnecting metabolic pathways that generate myriad metabolites including ATP. A longstanding conundrum is the inability to account for ~60% of ATP turnover in human RBCs. Processes that may consume this 'lost' ATP, include autonomous motion of the cell membrane called 'flickering', and maintenance of the biconcave-disc shape. NMR spectroscopy of quadrupolar nuclei in chiral aligned media, and isotopomer analysis will be used to define the kinetics of metabolism and membrane processes and thus help define the molecular basis of major blood disorders.
