Summary
Cardiovascular disease (CVD) claims 1 person every 10 min in Australia and causes 1 in 3 deaths worldwide. The molecular and cellular processes underlying atherosclerosis, vascular injury and thrombosis are highly complex and not well understood. A multifaceted approach is needed to effectively address these key challenges. This Program brings together world experts in these areas to interrogate gaps in our basic understanding of CVD, and to develop novel therapies for CVD patients by exploiting ....Cardiovascular disease (CVD) claims 1 person every 10 min in Australia and causes 1 in 3 deaths worldwide.

Summary
Vascular Dementia (VaD) is the second most common cause of dementia after Alzheimer's disease. In fact, it may be a preventable cause of dementia. Yet it has been relatively neglected by researchers until the last decade, which has seen an upsurge of interest in this disorder. There is no consensus on the criteria for dementia. The profile of early cognitive impairment due to vascular factors is still poorly understood, and the longitudinal course of VaD as defined by modern criteria has not bee ....Vascular Dementia (VaD) is the second most common cause of dementia after Alzheimer's disease. In fact, it may be a preventable cause of dementia. Yet it has been relatively neglected by researchers until the last decade, which has seen an upsurge of interest in this disorder. There is no consensus on the criteria for dementia. The profile of early cognitive impairment due to vascular factors is still poorly understood, and the longitudinal course of VaD as defined by modern criteria has not been studied. There have been few studies of the progressive changes in MRI in patients with cerebrovascular disease. The overlap of VaD and Alzheimer's disease (AD) remains a problem for taxonomists and clinicians. One approach to the study of VaD is to examine a high risk group of subjects longitudinally to determine the early features, the risk factors and progressive changes. With this in mind, we began studying a cohort of stroke patients who are at high risk of VaD, in 1997-1999, and are following them longitudinally. The follow-up is now in its third year, and three neuropsychological assessments and two MRI-MRS scans have been performed. We propose to extend the follow-up to 5 years, with repeat neuropsychiatric, neuropsychological and MRI-MRS investigations, and wherever possible to necropsy, to determine the nature of vascular pathology that underlies cognitive impairment. Our cohort of stroke patients is arguably the most comprehensively assessed such cohorts internationally, and presents an excellent opportunity for a long-term follow-up study.Read moreRead less
BioPolymer Fibres For Remodelling Mdx And Damaged Muscle

Summary
This project aims to generate new, smart polymers for use in re-building muscle that has degenerated due to disease and-or trauma damage. The merger of smart polymers with biologically based solutions and cells has great potential to improve outcomes of treatments of damaged muscle in diseases such as Muscular Dystrophy.
The Effects Of Tonic Muscle Pain On The Sympathetic And Somatic Motor Systems In Human Subjects

Summary
The main objective of this proposal is to reveal the effects of nociceptive reflexes in humans, and thus identify their functional and clinical implications. By performing invasive recordings from the nerves that control blood vessels and muscles in healthy volunteers subjected to long-lasting (~1 hour) experimental pain, this work will increase our understanding of the adaptive changes that pain induces and improve treatments to prevent pain from becoming chronic.
Local Sleep In The Awake Brain: An Underlying Cause Of Neurobehavioural Deficits In Sleep Apnea?

Summary
Obstructive sleep apnea (OSA) is a common sleep disorder which significantly impacts daytime functioning leading to excessive sleepiness, and problems with attention and thinking. Currently, the causes for cognitive impairment in OSA (including attentional lapses and performance deficits) are poorly understood. In the awake state, groups of neurons can briefly go “offline” as they do in sleep. These periods of “local sleep” may explain impaired task performance in OSA.
We have discovered a single tumour factor which causes cancer cachexia, a wasting condition that is one of the worst complications of malignancy, for which there is no current effective treatment. We have developed antibodies which effectively block this condition in preclinical models and have produced human/humanised version of this. This application is to characterise these human antibodies to allow us proceed to clinical trials.
Vascular And Neurogenic Determinants Of Hypertension In Chronic Kidney Disease

Summary
You are as old as your arteries, and people with kidney disease have arteries that age fast. They also have overactive sympathetic nerves, and it is not clear if the blood vessels or nerves are responsible for the high blood pressure that puts strain on the heart and other organs of these patients. We will use an animal model to determine if therapy for hypertension reduces the stiffness of blood vessels or elevated nerve activity. Our results will enable better treatments for kidney failure.
