Summary
Stonemasons who have worked with engineered stone have been shown to develop a rapidly progressive and potentially fatal form of silicosis. This research will use data from affected workers from Victoria, Western Australia and Queensland. The research will comprise a suite of projects to investigate many uncertainties related to radiological screening methods, as well as investigating new methods to assess disease severity and identify indicators of progression to inform future practice.
The Fluid-Particle Mechanics of a Synthetic Jet-based Dry Powder Inhaler. This project aims to untangle the fundamental principles that govern the fluid mechanics and particulate interactions in a novel concept chip-based micro-zero-net-mass-flux (micro-ZNMF) jet-assisted dry powder inhaler (DPI). Respiratory diseases affect 6.2 million Australians. The treatment of these diseases is hampered by the poor efficiency of current delivery systems, with conventional DPI devices exhibiting sub-optimum ....The Fluid-Particle Mechanics of a Synthetic Jet-based Dry Powder Inhaler. This project aims to untangle the fundamental principles that govern the fluid mechanics and particulate interactions in a novel concept chip-based micro-zero-net-mass-flux (micro-ZNMF) jet-assisted dry powder inhaler (DPI). Respiratory diseases affect 6.2 million Australians. The treatment of these diseases is hampered by the poor efficiency of current delivery systems, with conventional DPI devices exhibiting sub-optimum performance, delivering typically less than 20% of the loaded dose to the target site, the lungs. The new fundamental knowledge resulting from this research will enable the engineering of a high-efficiency groundbreaking DPI, with the potential to be fully adaptive user-specific benefiting millions of Australians.

Summary
There is growing interest in the role of microbial-based strategies including faecal microbiota transplantation (FMT) for the treatment of inflammatory bowel disease. This project will develop such strategies into valid treatment options through a combination of clinical & basic science work including (1) characterising viral & fungal factors of importance, (2) evaluation of novel orally-delivered formulations of FMT, and (3) development of better defined, more reproducible microbial treatments.
Adaptation of respiratory chemoreception: role of inhibitory neuropeptides. The project aims to investigate how the retrotrapezoid nucleus (RTN) is involved in respiratory adaptation to hypercapnia. Chemoreceptor neurons in the RTN are crucial for life however, the mechanisms that underlie their basal and stimulated activity, to control breathing, remain to be clarified. This project will investigate the role of galanin in RTN-mediated regulation of breathing.

The project aims to investigate how the retrotrapezoid nucleus (RTN) is involved in respiratory adaptation to hypercapnia. Chemoreceptor neurons in the RTN are crucial for life however, the mechanisms that underlie their basal and stimulated activity, to control breathing, remain to be clarified. This project will investigate the role of galanin in RTN-mediated regulation of breathing. The project looks to determine instructive and multifunctional roles of peptidergic chemosensory neurons and their contribution to local inhibitory control of the respiratory network. New knowledge from the project may in the future assist translational research into respiratory disorders and lead to technological advances.Read moreRead less
Engineering an environmentally-friendly metered dose inhaler. This project aims to deliver a novel simulation framework to accurately predict the behaviour of metered dose inhaler sprays using advanced numerical methods for flash-evaporating turbulent flows developed by the investigators. The project expects to generate new knowledge of the complex physics which occur in these devices through a first of its kind combination of unsteady non-equilibrium thermodynamics, turbulence and spray models. ....Engineering an environmentally-friendly metered dose inhaler. This project aims to deliver a novel simulation framework to accurately predict the behaviour of metered dose inhaler sprays using advanced numerical methods for flash-evaporating turbulent flows developed by the investigators. The project expects to generate new knowledge of the complex physics which occur in these devices through a first of its kind combination of unsteady non-equilibrium thermodynamics, turbulence and spray models. Expected outcomes of this project include a novel ability to predict and optimise the performance of inhalers to suit environmentally-friendly replacement propellants. This will significantly benefit the pharmaceutical sector as it will accelerate the design of next-generation inhalers and propellants.Read moreRead less

Summary
Following basic epidemiology principles, no infectious disease occurs ‘randomly’ and its occurrence follow logical and predictable patterns. The presence of an infectious agent is unlikely sufficient to explain these patterns and most aquatic diseases result from the complex interaction between the agent, the host and its environment. Therefore, the targeted outcome for a POMV control plan is threefold: 1.

The presence of an infectious agent is unlikely sufficient to explain these patterns and most aquatic diseases result from the complex interaction between the agent, the host and its environment. Therefore, the targeted outcome for a POMV control plan is threefold: 1. Decrease transmission between infected and susceptible fish groups – this requires identifying risk factors associated with the introduction, spread, and maintenance of the pathogen within the industry; 2. Decrease the number of susceptible fish – this mainly requires identifying risk factors associated with the susceptibility of the host (e.g. husbandry-related stress) and the development of a safe and effective prophylaxis; 3. Decrease the amount of virus in the environment - this requires detecting infected fish cage(s) early to implement timely control strategies. Diagnostic capacity to confirmed POMV outbreak has been developed and is currently used in routine by the industry. A vaccine against POMV is currently under development at the Tasmanian Aquatic Animal Health and Vaccines Centre of Excellence and will be available in the future. However, little is known about risk factors specific to POMV and about its full economic impact. We define as a ‘risk factor’ any attribute of the agent, the host or its environment that increases the risk and intensity of a disease outbreak. Most of the environmental risk factors (including farming practices) facilitate the introduction, transmission, or maintenance of the pathogen; while the host risk factors affect the susceptibility of the host and its capacity to become diseased. Like the closely related ISAv, the magnitude and occurrence of POMV outbreaks appeared to be highly variable. This supports the existence of additional factors other than the POMV infection that contribute to the intensity of an outbreak. It is anticipated that by identifying and intervening on some of the manageable risk factors, the frequency and the severity of POMV outbreaks can be reduced. Objectives: 1. Describe the occurrence of POMV outbreaks in the Tasmanian salmon industry 2. Quantify the direct financial impact of POMV mortality to the Tasmanian salmon industry 3. Identify potential management, environmental and stock risk factors directly or indirectly increasing the risk and intensity of a POMV outbreaks Read moreRead less

This project aims to elucidate the roles of newly discovered steroid receptors in the functions of mitochondria. The project will characterise their impact on cellular respiration, oxidative stress, and the induction of inflammation. By defining these processes in the healthy state and in response to common environmental challenges of infection and smoke exposure, the project will characterise the fundamental biology of entirely new processes of how normal body hormones and administered steroids may function. This may eventually lead to new and more effective ways to control inflammation that will have significant benefits to mammalian health and improve health care and agriculture outcomes.Read moreRead less
