Advanced nanotechnologies for targeting biofilms. This project aims to develop nano-particulate systems based on a single platform technology that can be delivered as an aerosol. The current lack of a suitable formulation and delivery system hinders the eradication of fungal and bacterial biofilms from surfaces. These new systems will have enhanced residency time, penetration properties and effectiveness in biofilms. This project intends to understand the properties that govern the formation and interactions in these systems, and develop in-vitro tools that the wider scientific community can use. The project expects to generate a single platform that can be used for the eradication of biofilms in numerous applications, from healthcare to agriculture.Read moreRead less
A Randomised Controlled Trial Of Interventional Versus Conservative Treatment Of Primary Spontaneous Pneumothorax

Summary
Primary spontaneous pneumothorax (PSP) is a collapsed lung that occurs in otherwise healthy people without underlying lung disease. Current standard treatment is to insert a chest drain into the chest to remove the air around the collapsed lung so that the lung re-inflates rapidly ("interventional treatment"). We will determine whether doing nothing, i.e. letting the lung re-inflate slowly on its own over several weeks ("conservative treatment"), is just as good or even better for patients.
Smartdrops - Shaping the future of particle technology. The aim of this project is to develop a particle engineering technology, based on microfluidics, that results in micro-droplets with controlled geometry and morphology. These Smartdrops will be used to target respiratory macrophages for the delivery of inflammatory suppressants, since their dimensions can be controlled to optimise lung deposition and macrophage recognition. The project aims to develop an aerosol inhaler and a series of phys ....Smartdrops - Shaping the future of particle technology. The aim of this project is to develop a particle engineering technology, based on microfluidics, that results in micro-droplets with controlled geometry and morphology. These Smartdrops will be used to target respiratory macrophages for the delivery of inflammatory suppressants, since their dimensions can be controlled to optimise lung deposition and macrophage recognition. The project aims to develop an aerosol inhaler and a series of physico-chemical and in vitro characterisation tools that will be used to study Smartdrop formation, aerosol properties and their interactions with cells. The outcome of this project is intended to be the development of a technology for treating chronic lung inflammation which could also be utilised for a number of other commercial applications.Read moreRead less
The role of electrostatic charge in airway deposition of aerosols. This project aims to unravel the importance of electrostatic charge in controlling deposition of aerosols in the respiratory tract. The expected outcome is a validated mathematical model for accurately predicting deposition behaviour of charged aerosol particles in human airways. Findings may ultimately be used to underpin novel prevention measures to reduce lung deposition of inhaled hazardous airborne particles to significantly ....The role of electrostatic charge in airway deposition of aerosols. This project aims to unravel the importance of electrostatic charge in controlling deposition of aerosols in the respiratory tract. The expected outcome is a validated mathematical model for accurately predicting deposition behaviour of charged aerosol particles in human airways. Findings may ultimately be used to underpin novel prevention measures to reduce lung deposition of inhaled hazardous airborne particles to significantly reduce health risks and costs. They may also be used to enable the development of new inhalation technologies based on electrostatic charge to improve aerosol drug delivery to the lungs of patients with respiratory diseases.Read moreRead less

How innate lymphoid cells regulate mammalian lung development. This project aims to determine the ability of a subset of lung resident immune cells to promote normal lung development through the regulation of stem cells. The lung is constantly exposed to countless environmental challenges including microbes. Mammals’ local immune systems protect the lung from these challenges. This is particularly important in early-life when the lung is still developing. However, impaired lung development affec ....How innate lymphoid cells regulate mammalian lung development. This project aims to determine the ability of a subset of lung resident immune cells to promote normal lung development through the regulation of stem cells. The lung is constantly exposed to countless environmental challenges including microbes. Mammals’ local immune systems protect the lung from these challenges. This is particularly important in early-life when the lung is still developing. However, impaired lung development affects humans and livestock, costing >$3 billion p.a. The intended outcome is to identify basic biological processes involved in normal mammalian lung development, which may lead to strategies to prevent chronic lung diseases in humans and animals.Read moreRead less
The COVID-19 pandemic has highlighted the risk of closed, indoor settings due to accumulation of aerosols generated from breathing, speaking, coughing or sneezing. Any airborne threat, whether an infectious virus or a chemical agent, will create a higher exposure in indoor settings. To mitigate this risk, using inter-disciplinary expertise, this research will improve preparedness, reduce health impacts of airborne threats, inform worker and occupant safety, building design and healthy futures.
Clinical Impact Of Clonal Pseudomonas Aeruginosa In Cystic Fibrosis

Summary
In patients with cystic fibrosis (CF), the normal defence mechanisms are compromised by an inherent genetic fault which results in an extremely sticky and dehydrated mucus. The respiratory system is unable to eradicate microbes (infection) from the lungs of patients with CF which begin to multiply and cause infection and inflammation. Recurring infections are treated with multiple courses of antibiotics and frequent hospitalisation and eventually result in premature death. This study focuses on ....In patients with cystic fibrosis (CF), the normal defence mechanisms are compromised by an inherent genetic fault which results in an extremely sticky and dehydrated mucus. The respiratory system is unable to eradicate microbes (infection) from the lungs of patients with CF which begin to multiply and cause infection and inflammation. Recurring infections are treated with multiple courses of antibiotics and frequent hospitalisation and eventually result in premature death. This study focuses on the major bacterial problem, Pseudomonas aeruginosa. Several studies from Australia and the UK, including our own have shown that about 30% to 45% of patients share the same strain of Pseudomonas aeruginosa within a centre. We know that two dominant strains of Pseudomonas aeruginosa are found in CF centres on the eastern board of Australia. This is unexpected as this bacterium is usually acquired from the environment. The emergence of these clonal strains is causing increasing anxiety in the CF community. This study is designed to provide vitally needed information on the clinical implications of being infected by an clonal strain of Pseudomonas aeruginosa and the risk factors for the acquisition of an clonal strain. This new information will provide a rationale basis for the need for changes to infection control policies (including patient segregation), better outcome predictors for patients infected with clonal strain of Pseudomonas aeruginosa.Read moreRead less

These proteases have unique yet poorly understood mechanisms of regulation. The aim of the project is to use a novel suite of molecular tools and genetically modified mice to identify the critical regions of transcripts that post-transcriptionally regulate the production and storage of these proteins. The project aims to identify the RNA binding proteins, microRNAs and other novel factors that also regulate them. This is expected to elucidate the post-transcriptional mechanisms of regulation of MC proteases.Read moreRead less
