Summary
Whilst ambulatory blood pressure monitoring data has been shown to be a good predictor of cardiovascular events, there remains controversy as to its utility in clinical practice. This project will use data from existing population and clinical cohort studies to examine the role of ambulatory blood pressure in risk assessment and hypertension management in Australia and around the globe. The findings are likely to have a major impact on clinical guidelines for hypertension management.

Summary
Brain cells that control the cardiovascular system are thought to have stopped dividing by adulthood. We recently discovered that this is not the case. Our initial findings suggest that these nascent cells might be important for maintaining normal blood pressure. This work will allow us to elucidate the function of these nascent cells and how they integrate into the circuit that controls the cardiovascular system. Our findings will be fundamental for understanding diseases such as hypertension.
A novel sensory neural circuit has been identified innervating the airways and lungs. The anatomical organisation of this circuit has been described to some extent in previous studies, however there is a significant gap in knowledge with respect to its functional importance. This project will develop methods to address this knowledge gap and in doing so the project will firstly describe how this circuit controls breathing under normal conditions and secondly how this becomes dysregulated during
Shared Team Approach Between Nurses And Doctors For Improved Risk Factor Management (STAND FIRM)

Summary
There are many proven treatments for preventing people with stroke from having a recurrent event, e.g. maintaining blood pressure at acceptable levels. However, uptake of therapies is poor. We will assess whether patients receiving individualised management plans, prepared and administered by both doctors and nurses will have risk factors controlled better than those receiving usual care. The plan includes education of patients to help them have more control over their own care.
Neural migration: Which cells advance and which stay behind? This project aims to examine the neural crest cells that colonise the developing gut and to identify why some cells advance while others stay behind to populate a region. Directed cell migration is essential for normal development, including for the nervous system. In most of the migratory cell populations that have been analysed to date, all of the cells migrate as a collective from one location to another. However, there are also mi ....Neural migration: Which cells advance and which stay behind? This project aims to examine the neural crest cells that colonise the developing gut and to identify why some cells advance while others stay behind to populate a region. Directed cell migration is essential for normal development, including for the nervous system. In most of the migratory cell populations that have been analysed to date, all of the cells migrate as a collective from one location to another. However, there are also migratory cell populations that must populate the areas through which they migrate, and thus some cells get left behind while others advance. The planned data are likely to be relevant to other cell populations that also populate the areas through which they migrate, including neural crest-derived melanocytes and Schwann cell precursors.Read moreRead less
Development of sympathetic nerve pathways. The mature nervous system contains many types of neurons connected in precise ways. Developing neurons must make many decisions about what type of neuron to become and what connections to make. This study looks at the mechanisms that guide the developing neurons in these important decisions.
Wiring the gut's nervous system: formation and maturation of synapses. This project aims to determine how nerve circuits controlling intestinal functions develop; specifically how communication between specific nerve cells is established once they appear in the embryonic gut. It will fill a major hole in existing knowledge of mechanisms regulating the development of normal digestive behaviours.
How the brain regulates blood pressure. This project will test whether a group of nerve cells in the rostral ventrolateral medulla generate sympathetic activity in blood vessels. The brain regulates blood pressure through several pathways, including nerves in the sympathetic nervous system that constrict blood vessels and increase the heart rate. Activity of these sympathetic nerves regulates blood pressure, but it is unknown which nerve cells in the brain cause this activity. This information i ....How the brain regulates blood pressure.

The brain regulates blood pressure through several pathways, including nerves in the sympathetic nervous system that constrict blood vessels and increase the heart rate. Activity of these sympathetic nerves regulates blood pressure, but it is unknown which nerve cells in the brain cause this activity. This information is essential to understand how blood pressure is controlled under healthy conditions.Read moreRead less
Optimising Non-invasive Ventilation At Birth For Preterm Infants

Summary
Infants born very premature require respiratory support at birth to make the transition to newborn life. As these infants are very immature and prone to injury, modern respiratory care strategies utilise the least invasive approaches mainly applied using a facemask. However, we have discovered that the larynx is closed at birth and thereby prevents air from entering the lung. This application is focussed on optimising the efficiency of facemask ventilation at birth and stimulating breathing.

Understanding interactions between gut epithelial stem cells and neurons. This project aims to investigate the interaction between gut neurons and the epithelial stem cell compartment, as well as the relationship between age-related loss of enteric neurons and changes in gut epithelial stem cells. This project will include novel co-culturing of organoids and enteric neurospheres, which will identify mechanisms by which nerves influence the epithelia.

This project will include novel co-culturing of organoids and enteric neurospheres, which will identify mechanisms by which nerves influence the epithelia. The outcome of the project will be a better understanding of the biology of the body’s most highly proliferative, long-lived stem cells, intestinal epithelial stem cells. This could have significant long term impact on the quality of life in an ageing population.Read moreRead less
