Summary
MLKL is a protein naturally found inside cells. MLKL is activated by inflammation. Once activated, MLKL relocates to the outer periphery of cells and kills them. Gut cells are especially vulnerable to death-by-MLKL and this problem causes Inflammatory Bowel Disease. Using cutting edge microscopy, we have discovered how MLKL moves to the periphery of cells prior to killing them. We will test if blocking this movement of MLKL to the cell periphery stops gut death and Inflammatory Bowel Disease.

Summary
Chronic visceral pain is a common and debilitating condition arising from numerous diseases that affect our internal organs. There is a desperate need for more information about the mechanisms responsible for signalling chronic visceral pain to provide therapies and potentially find a cure for it. Our research focuses on ?-conotoxins (small peptides from marine cone snail venom) as novel potential therapeutic agents for the treatment of chronic visceral pain.
The Structural Basis For Glutamate Transporter Function

Summary
Glutamate transporters are vacuum cleaners in the brain that suck the neurotransmitter glutamate into cells. When the glutamate vacuum breaks down or becomes blocked, glutamate levels outside cells increase, leading to cell death in the brain. This process underlies the damage in many brain diseases including Alzheimer’s disease and stroke. The aim of this project is to understand the mechanism of the glutamate vacuum cleaner so we can develop therapeutics to fix it when it breaks down.

The loss of hand function will affect every aspect of an individual’s life. This includes the ability to feed and care for themselves and the ability to work and participate in family life. For people recovering from problems such as trauma, burns or surgery affecting the hand, careful management of hand rehabilitation can influence the outcome for the patient significantly.

This includes the ability to feed and care for themselves and the ability to work and participate in family life. For people recovering from problems such as trauma, burns or surgery affecting the hand, careful management of hand rehabilitation can influence the outcome for the patient significantly. In order to reduce the possibility of mobility difficulties occurring, including loss of joint range of motion, muscle and tendon sheath adhesions or non-functional scar tissue formation, continuous passive motion (CPM) is often indicated. Additionally, for people with reduced mobility of the hand due to upper limb paralysis, such as those with cervical spinal cord injury, stroke, cerebral palsy or peripheral nerve injury, disregard for management of the maintenance of the joint range of motion of the effected hand will result in contracture and limited joint range of motion. Such syndromes will reduce hand function, which is already limited by paralysis, and will negatively affect potential outcomes for aggressive rehabilitation techniques, such as tendon transfer surgery and functional neuromuscular stimulation. Therefore, in such cases, CPM is also indicated. Current devices applying CPM have shown to be effective in minimising the syndromes indicated above and these results are summarised in the Background and Research Plan attached to this proposal. Unfortunately, the use of such devices is not always prescribed by clinicians. This is due, mainly, to the limitations of these devices that are in the marketplace. These limitations include lack of secure finger placement, lack of portability, the inability to provide specialised therapy to specific joints and inflexible programming. This proposal introduces an improved device to be developed and these improvements form the proposal aims below. Given such an improved device, which can overcome many of the problems with current CPM machines, it is likely that that the clinical application of CPM will achieve the greater degree of prescription and application in hand rehabilitation. These improvements should overcome the clinical reticence to use these devices and restore a balance by increasing their use to the level that the scientific literature indicates they should have. The overall aim of the proposal is to take the device to a stage where it is ready for clinical trial.Read moreRead less
We will conduct a survey of respiratory symptoms, lung function, smoking status, occupational exposures, and other risk factors among 3200 people aged 40 years and over living in five Australian communities: Melbourne, Sydney, Tasmania, Busselton (WA), and the Kimberley region (WA). In the Kimberley we will survey 400 Aboriginal people and 400 non-Aboriginal people.

In the Kimberley we will survey 400 Aboriginal people and 400 non-Aboriginal people. We will use a survey methodology that has been developed by an international expert panel and has been implemented in many other countries (in North and South America, Asia, and Europe). This study will provide the first nationally-representative information on the burden of chronic obstructive pulmonary disease (COPD) and the opportunities for health gain by improving the management of this illness. In Australia, COPD is a relatively silent and under-recognised disease but nevertheless is the third most important contributor to the burden of disease and the third leading cause of hospital admission as well as being the underlying cause of 4.2% of all deaths. The information we will collect is needed to form a basis for prevention and disease management interventions to reduce the burden of COPD, particularly among population sub-groups who are disproportionately affected, either due to greater exposure to risk factors (mainly tobacco smoking and occupation), greater susceptibility, under-recognition and under-diagnosis, or inadequate disease management. Importantly, the study will serve to raise awareness about the hazards of smoking for all Australians. By identifying target groups, prevalent exposures and management deficiencies, it will lead the way towards policy-relevant randomised controlled trials testing community-based interventions to prevent COPD and-or manage it more effectively. The information collected will help advance knowledge of the prevalence, burden and treatment of COPD that will be relevant to communities throughout the world.Read moreRead less
The Clinical Utility Of Small Airway Function Tests In Paediatric Respiratory Disease

Summary
Respiratory disease is an important child health issue with long term implications into adulthood. The evaluation of small airways involvement in disease processes, using an accurate sensitive measures of function, such as forced oscillation technique and multiple breath washout, potentially facilitates not only early detection of disease, but instigation of earlier treatment, better assessment of response to treatment, and ultimately better outcome.
Targeted Disruption Of Lipoxygenase Enzymes To Prevent Oxidative Stress-mediated Pathologies In The Male Germline

Funding Amount
$408,768.00
Summary
An estimated 80 million individuals suffer from infertility globally with at least 50% of these cases due to defects in sperm function. Unfortunately, due to a severe lack of knowledge surrounding sperm biology and dysfunction, no successful curative or preventative measures have been established. My project will study why sperm cells die and investigate new ways to limit cellular stress so we can develop new therapeutic strategies to mitigate the growing problems in male reproductive health.

Summary
We will investigate the role of the orbitofrontal cortex (OFC) in decision-making, particularly the effect of hyperactivity in the medial vs. ventrolateral orbitofrontal cortex on decision-making. Hyperactivity in these structures has been linked to obsessive compulsive disorder and, in line with the distinct functions of the different regions of OFC, we develop and test a novel hypothesis as to the psychological and neural bases of the obsessions and compulsions distinctive to that disorder.
