RadioGenes2: Modelling complex biomolecular interactions in radiated tumours: Towards understanding the genesis of therapeutic radioresistance. About 45% of bladder cancer patients require radiotherapy or surgery. Radiotherapy has a failure rate of ~50%. Surgery (bladder removal) diminishes quality of life considerably.

About 45% of bladder cancer patients require radiotherapy or surgery. Radiotherapy has a failure rate of ~50%. Surgery (bladder removal) diminishes quality of life considerably. Modelling complex gene interactions in radiated cancer cells will provide crucial knowledge on the molecular genesis of radiotherapy-resistance of tumours. Our findings will provide: (i) an accurate mathematical/computational model for diagnosing radiosensitivity; (ii) further insights to be applied in the pharmaceutical sector such as the discovery of novel molecular targets that have the potential to increase radiotherapy success ratios; (iii) a holistic modelling technique applicable to a larger diversity of tumours.Read moreRead less
Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to ....Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to improve radiotherapy treatments in patients with small lesions with sizes of up to a few centimetres. This will lead to an improved outcome for some cancer patients.Read moreRead less
A Phase III Trial Comparing Adjuvant Versus Salvage Radiotherapy For High Risk Patients Post Radical Prostatectomy

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.
Correction of the Effects of Gradient Field Nonlinearity in Magnetic Resonance Imaging - A Complete 3-Dimensional Approach. The outcomes of this research will have direct benefits to various areas of diagnostic and interventional medicine especially in neurological diseases such as Alzheimer's disease, stroke, multiple sclerosis or brain tumors. The techniques developed in this project will in general enable MRI to provide a higher quality service to the community.
There is a need for a greater understanding of the complex relationship between sun exposure and the production of Vitamin D. This study will expand on the recently-completed AusD study to examine how personal, behavioural, and environmental factors impact on intra-individual seasonality in Vitamin D production. The study findings will guide the development of specific, evidence-based public health recommendation that balance the risks and benefits of sun exposure.
Benefit Of 2D-strain Surveillance In Improving Cardiovascular Outcomes In Cancer Patients Undergoing Cardiotoxic Chemotherapy

Summary
Cancer survivors are susceptible to heart failure (HF) caused by heart muscle damage from chemotherapy. The current testing for this problem is based on a measure that cannot identify minor changes of cardiac function. Cardiac strain is a sensitive new marker of cardiac function which is predictive of overt dysfunction & HF. This study seeks to identify whether strain can be used to assign treatments that lead to improved cardiac function and are eventually associated with a reduction in HF.
Identification Of Germline Variation That Predicts Progression Free Survival Following Chemotherapy For Advanced Ovarian Cancer

Funding Amount

Summary
Women diagnosed with ovarian cancer typically undergo surgery, followed by chemotherapy. However, the efficacy of chemotherapy varies widely, with some women responding well, whilst others are exposed to the toxic effects of a treatment that does them little good. We aim to identify the genes which explain why there are differences in response. This will lead to more individualised chemotherapy and improved outcomes for women with ovarian cancer.
Quantification issues in corporate valuation, the cost of capital, and optimal capital structure. An estimate of the firm's cost of capital is probably the most important calculation required in corporate finance. It is used as the discount rate in valuation and capital budgeting decisions and forms the basis of pricing structures for many regulated industries. Corporate finance theory has identified the key inputs used to calculate the cost of capital, but the current literature falls short o ....Quantification issues in corporate valuation, the cost of capital, and optimal capital structure. An estimate of the firm's cost of capital is probably the most important calculation required in corporate finance. It is used as the discount rate in valuation and capital budgeting decisions and forms the basis of pricing structures for many regulated industries. Corporate finance theory has identified the key inputs used to calculate the cost of capital, but the current literature falls short of precisely quantifying and measuring many of these inputs. The outcomes from this project will be a framework to quantify three key aspects of the cost of capital - the value of dividend imputation tax credits, the assessment of the optimal capital structure for the firm (in particular, the quantification of bankruptcy and agency costs associated with debt financing), and the estimation of the firm's marginal tax rate.Read moreRead less

Variations in industry performance within and across nations has resulted in renewed interest in the institutional governance systems that generate national competitive advantage and innovation. There has also been an increased focus on the impact of sustainability and environmental costs on corporations. The significance of this project to the nation and the community is that it develops an understanding of the role played by industry institutions in transforming corporate and industry approaches to sustainability. This study will show how industries and corporations respond to sustainability over time and the impact of these changes on major stakeholders (communities; shareholders; employees).Read moreRead less
Quantifying the impacts of environmental stress on marine microorganisms. Microorganisms underpin marine ecosystem health, yet there is limited understanding of how they will respond to different environmental pressures. This project will resolve this critical knowledge gap by developing a unique molecular platform for deriving quantitative stress thresholds for microbial communities inhabiting key reef habitats (seawater, sediments, invertebrates). Quantifying how reef microorganisms respond to ....Quantifying the impacts of environmental stress on marine microorganisms. Microorganisms underpin marine ecosystem health, yet there is limited understanding of how they will respond to different environmental pressures. This project will resolve this critical knowledge gap by developing a unique molecular platform for deriving quantitative stress thresholds for microbial communities inhabiting key reef habitats (seawater, sediments, invertebrates). Quantifying how reef microorganisms respond to a broad suite of environmental perturbations (temperature, nutrients, contaminants), will generate stress-response data that can be incorporated alongside eukaryotic data in environmental assessments, greatly improving the ecological relevance and reliability of risk and vulnerability assessments.Read moreRead less
