Summary
The NO/cGMP signalling pathway, which is central to cardiovascular physiology and protection against disease, is only fully effective when there are adequate levels of zinc in the vascular endothelium. This is especially important where zinc stores are depleted (elderly, smokers, diabetics and kidney disease). There is an urgent clinical need to implement strategies to monitor vascular Zn status. This application will explore the underlying science and translate these to the clinic.

Summary
Zinc is an essential dietary component that serves a number of functions in the lungs. It is both an anti-oxidant and anti-inflammatory agent. Some airway inflammatory diseases such as emphysema may involve a critical loss of lung zinc. We believe that cigarette smoke causes the loss of zinc and this prevents the lung macrophages from working properly to clear bacteria and dead cells. This will provide a foundation for our long term goals of better clinical management of emphysema.
Airway Epithelial IAPs And Their Interaction With Zn Ions

Summary
The air we breathe contains a variety of harmful substances. Damage to the lining involves death of the ciliated cells that line the airways. We have shown that zinc protects these cells from premature death. This application focuses on a family of proteins called IAPs which bind zinc and regulate cell death in other tissues. This project focusses on how the IAPs and Zn may act together to mainitain healthy airways and how abnormalities of these may occur in people with asthma.

Summary
This project will use a panel of Zinquin-derived Zn fluorophores developed in our laboratory, as well as probes for the mammalian family of vesicular ZnT transporters, to carry out a study of the normal physiology of Zn in the respiratory system and potential abnormalities of this in patients with chronic inflammatory respiratory disease (asthma, COPD, chronic smoking). Chronic inflammatory diseases of the respiratory tract affect a significant proportion of the Australian community.

Chronic inflammatory diseases of the respiratory tract affect a significant proportion of the Australian community. For example, asthma affects 12% of adults and amongst these, 15% waken weekly or more often with their asthma while 6% are hospitalized annually. There is a need to understand the basic mechanisms underlying these diseases so that new strategies can be developed to modify bronchocondtriction and inflammation. The project will provide new knowledge concerning the physiology of Zn in the respiratory epithelium and interactions between Zn deficiency and oxidants on injury in the respiratory tract. The usefulness of easily accessible nasal epithelial cells as a measure of Zn and Zn transporter levels deeper in the respiratory tract will be assessed. The project encompasses a number of fields and utilizes in vitro cellular and animal models, as well as tissues from human subjects.Read moreRead less
Solid Oxide Electrolysis Cells with Novel Perovskite-based Cathode. The electrochemical reduction of CO2 and steam to value-added fuels in a high-temperature solid oxide electrolysis cell (SOEC) is practically promising, but technologically challenging. This project aims to develop next generation SOECs using a perovskite-based cathode and scale-up engineering for rapid, bulk production of H2, CO and syngas fuels. Expected outcomes include material engineering, new knowledge on energy conversion ....Solid Oxide Electrolysis Cells with Novel Perovskite-based Cathode.
