New photoinitiators and polymers for tack-free LED cured surface coatings. This project aims to develop surface coatings curable by energy from Light Emitting Diodes (LEDS) by overcoming existing hurdles, while improving workplace health and safety.
The project expects to achieve this by developing a new class of photoinitiator molecules, with enhanced reactivity, via a unique understanding of synthesis, photochemistry and commercial coatings formulation.

The project aims to address a growing problem of increasing energy consumption by storing intermittent energy from the sun in affordable and efficient flow batteries. The project expects to generate new knowledge in the areas of materials science and battery research by using innovative theoretical chemistry approaches to studying electrochemical properties of nitroxide radicals in ionic media. The project aims to develop radical organic flow batteries by utilising ionic liquids to stabilise radicals. Intended outcomes of the project include improved efficiency of flow batteries that can store energy from widely used solar panels. This should provide significant benefits to Australia’s effort to switch to renewable energy technologies. Read moreRead less
The role of hypohalous acids and related oxidants in the oxidative damage of biological systems: a computational investigation. The aim of this project is to decipher the molecular mechanisms of key reactions involved in oxidative damage to biomolecules. The study will lead to a better understanding of oxidative stress in biological systems and its role in chronic inflammatory disease, heart disease, and cancer.

A Phase III Trial Comparing Adjuvant Versus Salvage Radiotherapy For High Risk Patients Post Radical Prostatectomy

Funding Amount

Summary
About half of all patients Treated with an operation to remove their prostate cancer have a high chance of the cancer coming back. Giving immediate radiotherapy to all patients will improve cure rates but does not benefit all men and can cause significant side effects. This study explores whether it is safe to wait and only give radiotherapy when there is a rising PSA after surgery indicating active cancer. A total of 470 men from Australasia will enter this study comparing the two approaches.
Role Of Transition Metal Ions And Redox Activity In The Development Of Atherosclerotic Plaques

Summary
Metal ions such as iron and copper have been reproted to be present in the lesions present in diseased human arteries and it has been suggested that these metal ions contribute to the development of atherosclerosis (hardening of the arteries) via their ability to catalyse the formation of highly reactive molecualr fragments called free radicals. Though metal ions are known to catalyse such reactions in test-tube experiments, both the presence of metal ions in diseased arteries and their ability ....Metal ions such as iron and copper have been reproted to be present in the lesions present in diseased human arteries and it has been suggested that these metal ions contribute to the development of atherosclerosis (hardening of the arteries) via their ability to catalyse the formation of highly reactive molecualr fragments called free radicals. Though metal ions are known to catalyse such reactions in test-tube experiments, both the presence of metal ions in diseased arteries and their ability to generate free radicals is controversial. This study will employ a novel, minimally-invasive, technique to assess the nature and quantity of metal ions present in well-defined human and animal lesions at different stages of lesion development. The ability of these metal ions to catalyse free radical formation from components present in the artery wall will also be assessed. The release of these metal ions from the artery wall to added organic molecules will be assessed as this might minimise their potential to cause damage, and provide a possible therapeutic strategy. These studies will therefore provide valuable information as to the significance and role of reactive metal ions in the development of human artery disease and the possible prevention, or minimisation, of such processes.Read moreRead less

Summary
The goal of the proposed research is to understand how dynamic changes to the chromatin genome packaging network, interact with the DNA damage response and gene expression machinery, to repair damaged DNA and the impact this has on cancer biology. To do so we are combining cutting edge molecular biology techniques with innovative novel microscopy methods developed by our research team, that far exceed the spatiotemporal resolution currently used to study chromatin biology.
Contribution Of Disturbed Blood Flow And Cerebral Metabolism To White Matter Damage In The Perinatal Brain

Summary
It has been known for some time that the white matter regions of the developing brain are particularly vulnerable to damage. These regions are deep in the brain near the ventricles, and are rich in myelin sheaths wrapped around the nerve fibres running from cell-rich areas in the outer layers of the brain to other regions, and down into the spinal cord. Damage to white matter usually leads to behavioural, learning and motor problems in the newborn infant - in its severest form, seen as cerebral ....It has been known for some time that the white matter regions of the developing brain are particularly vulnerable to damage. These regions are deep in the brain near the ventricles, and are rich in myelin sheaths wrapped around the nerve fibres running from cell-rich areas in the outer layers of the brain to other regions, and down into the spinal cord. Damage to white matter usually leads to behavioural, learning and motor problems in the newborn infant - in its severest form, seen as cerebral palsy. Such outcomes are often associated with the presence of asphyxia and infection during pregnancy, leading to the belief that the damage first arises while the baby is still in utero. In this application we suggest that asphyxia and-or infection during pregnancy cause prolonged disturbances in the regulation of blood flow and integrity of the blood-brain barrier in the developing brain, together with changes in metabolism that result in accumulation of prostaglandins and the toxic hydroxyl radical, leading irreversibly to cell death. If this series of events proves to be true, we have suggested and will test several protocols for protecting the fetal brain, which should be readily translatable to clinical practice.Read moreRead less
How Replication Stress Activates The Mitotic Telomere DNA Damage Response To Kill Cancer Cells

Funding Amount

Summary
We discovered a novel mechanism linking stress during DNA replication to difficulties with the cell division process, and identified how this turns on DNA damage response signals from the chromosome ends (i.e. “telomeres”). We have further identified that we can exploit this mechanism to kill cancer cells. In this project we will explore this newly discovered mechanism and identify how it can be targeted for therapeutic purposes.
Long-term Nerve Damage In Cancer Survivors: Identification Of Risk Factors And Optimal Assessment Strategies

Funding Amount

Summary
Nerve damage following chemotherapy treatment leads to early treatment cessation and long-lasting disability, developing with commonly used chemotherapies. There is a critical need to understand the mechanisms, optimize clinical assessment and develop interventions to prevent nerve damage. This project is designed to detect the impact of long-term nerve damage in cancer survivors and develop a risk profile based on clinical, neurophysiological and genetic factors.
