Summary
Prostate cancer is a major health problem in Australia, being the second leading cause of cancer deaths in men. Although there have been improvements in the diagnosis and treatment of prostate cancer, there are no effective treatments for advanced (metastatic) disease that has spread to other parts of the body.

Although there have been improvements in the diagnosis and treatment of prostate cancer, there are no effective treatments for advanced (metastatic) disease that has spread to other parts of the body. Currently, the only therapy for advanced disease involves the reduction in circulating androgens such as testosterone by surgical or medical castration, i.e. androgen ablation. Because prostate cells are dependent on testicular androgens for their growth and survival, surgical or medical castration results in an initial tumour regression. However, tumours inevitably develop resistance to androgen ablation therapy and regrow. In this study we aim to provide the most comprehensive analysis to date of the role of androgen signalling in the initiation and progression of prostate cancer. This will enable us to identify the most effective means of eliminating androgen-dependent prostate tumours and identify tumours with high metastatic potential. Our studies will indicate whether treatments targeting androgen signalling are a more effective strategy to inhibit prostate cancer growth while minimising undesirable side effects.Read moreRead less

Summary
Type 1 diabetes in childhood is a major cause of morbidity with an Australian prevalence of approximately 20 per 100,000 children under 15 years of age. The leading cause of death in type 1 diabetes in children and adolescents is diabetic ketoacidosis complicated by cerebral oedema (brain swelling), the origins of which remain unknown. This research is aimed at providing an insight into changes in the brain of children with diabetic ketoacidosis (DKA) and the relationship of these brain changes ....Type 1 diabetes in childhood is a major cause of morbidity with an Australian prevalence of approximately 20 per 100,000 children under 15 years of age. The leading cause of death in type 1 diabetes in children and adolescents is diabetic ketoacidosis complicated by cerebral oedema (brain swelling), the origins of which remain unknown. This research is aimed at providing an insight into changes in the brain of children with diabetic ketoacidosis (DKA) and the relationship of these brain changes to short and long term neuropsychological functioning. The major aim of this project is to provide an insight into brain changes of children with diabetic ketoacidosis (DKA) and the relationship of these brain changes to subseuqent brain function. This is a study where we will simply observe differences between newly diagnosed type 1 diabetic patients with no ktoacidosis, ketoacidosis or ketoacidosis with brain swelling over 6 months. We will measure brain function using various techniques includiung: magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS), electrophysiology (EEG) and neuropsychological tests. The significance of this project is that it will provide insight into the brain impairment of diabetic patients with and without DKA, and with brain swelling in the context of DKA. By further clarifying the nature of brain impairment we will provide early intervention strategies to improve psychological development of the young patients with diabetes. In addition to this we hope to better understand the origins of brain swelling during DKA and design treatment protocols that will prevent this devastating complication.Read moreRead less
