Improving Global Tuberculosis Control With The AuTuMN Platform

Funding Amount
$655,059.00
Summary
Tuberculosis (TB) is the world’s leading infectious killer, with the failure of global control responsible for the vast majority of Australia’s cases. Using our robustly developed software platform, we have performed several country-level studies to predict the future burden of disease and compare the impact of alternative responses to controlling the epidemic. In this project, we will extend our platform to perform simulations at the global level and answer key questions in TB control.
Neural Computations For Predictive Coding In Visual Cortex

Funding Amount
$479,832.00
Summary
The project aims to use the principle of "predictive coding" - a theory that promises to be a unified theory of the brain - to understand how the visual cortex makes predictions about future events, at cellular level. This basic knowledge will not only shed light on how the cerebral cortex functions at the cellular level, but may also clarify the neuronal basis of mental conditions such as schizophrenia and autism.
Neural Control Of Renin Expression By MicroRNA In Hypertension

Funding Amount
$805,972.00
Summary
We identified that mice bred to have high blood pressure have an overactive nervous system that affects a gene that controls a hormone in the kidney that increases blood pressure. The proposal will determine the effects of a novel treatment to alter the gene to reverse the changes in the kidney and thereby normalizing blood pressure. This will lead to new therapy and reduce the major risk factor of cardiovascular disease.
Our overall objective is to significantly improve the efficacy and efficiency of image-guided neurosurgery for brain tumours by including realistic computation of brain deformations, based on a biomechanical model, in a system to improve intra-operative visualisation, navigation and monitoring. The system will create an augmented reality visualisation of the intra-operative configuration of the patient’s brain merged with high resolution pre-operative imaging data.
A Pharmacological Approach To Define The Contribution Of Nav1.7 To Pain Pathways

Summary
Chronic pain is a debilitating condition that affects the life of one in five Australians and has significant socioeconomic impact. Currently available pain killers often do not work, or have intolerable side effects. We have discovered the most selective blocker for a specific type of sodium channel that is a known pain target and will use this novel molecule to gain insight into the mechanisms of pain and to develop new pain killers.
Characterisation Of Eurl, A Novel Gene Implicated In The Etiology Of Abnormal Brain Development And Intellectual Disability

Funding Amount
$597,541.00
Summary
Intellectual disability affects around one per cent of Australians, and can arise from genetic abnormalities during fetal life, such as through abnormal regulation of gene expression. We have identified a novel gene, known as eurl, which controls brain assembly as well as the ability of neurons to form functional connections within the brain. We will investigate how this novel gene controls brain development, and characterise eurl as a potential therapeutic target for learning and memory.
Imaging The Activation Of Sensory Nerve Endings That Detect Pain In The Colorectum

Funding Amount
$570,334.00
Summary
Within the gastrointestinal tract are sensory nerve endings that detect painful stimuli. In this project a new technique has been developed that allows us to monitor and record the activation of the particular sensory nerve endings that detect painful stimuli. This project will determine how these sensory nerve endings detect pain and how drugs might be used to relieve these unpleasant sensations arising from the gut wall.
Improving Patient Safety In Radiation Therapy With The Watchdog Real-time Treatment Delivery Verification System

Funding Amount
$593,742.00
Summary
Radiation therapy is a highly effective cancer treatment with extremely high doses delivered using very complex treatment machines. Unfortunately errors have occurred resulting in cases of patient death and mistreatment. We have developed a novel method to assess the treatment delivery in real-time to prevent errors. The method uses imaging devices that are already present on the treatment machine meaning that this method could have a major impact on patient safety in modern radiation therapy.
Improved Risk Assessment For Drugs Causing Cardiac Arrhythmias
Funder
National Health and Medical Research Council
Funding Amount
$638,166.00
Summary
Fatal heart rhythm disturbances are an all too common side effect of many drugs. Tests that are in place to guard against this are effective, but widely considered too stringent, meaning the development of potentially useful new therapeutics has been hampered. This study will characterise the precise mechanisms by which drugs cause arrhythmias and identify specific patterns on patient ECGs associated with the risk of rhythm disturbances that can be used in more effective clinical testing.
Reducing The Greatest Uncertainty In Radiotherapy.

Funding Amount
$594,197.00
Summary
The weakest link in radiotherapy is defining treatment volumes (contouring). Lack of accuracy and consistency in clinical trial contouring has been shown to result in reduced patient outcomes. Manual review of contouring is resource intensive, expensive and for advanced treatments unachievable in a timely fashion. We will assess an automated approach to contouring assessment using 4 clinical trial datasets, changing practice for future studies and enabling consistent assessment in the clinic.
