Summary
This proposal is aimed at determining the three dimensional structure of Thyroid Peroxidase, a protein found in the human thyroid gland that is important in the production of the hormone thyroxine. Thyroxine is involved in controlling the rate of metabolic processes in the body and influencing physical development.

Summary
Patients with early heart disease often present with shortness of breath with exercise, as myocardial reserve at that stage is usually sufficient to maintain normal function at rest . Indeed, much myocardial dysfunction may originate from the modern lifestyle, including inactivity, obesity, the metabolic syndrome and type II diabetes. The potential benefits of making a definitive early diagnosis are large, because it seems more likely that an impact can be made on the disease process (and theref ....Patients with early heart disease often present with shortness of breath with exercise, as myocardial reserve at that stage is usually sufficient to maintain normal function at rest . Indeed, much myocardial dysfunction may originate from the modern lifestyle, including inactivity, obesity, the metabolic syndrome and type II diabetes. The potential benefits of making a definitive early diagnosis are large, because it seems more likely that an impact can be made on the disease process (and therefore, outcome) than with late stage disease. Current treatment strategies are expensive and because they are directed at end-organ damage (heart failure, heart attacks etc), rather ineffective. This multispecialty, multidisciplinary group will undertake a series of unique studies aimed at identifying early cardiovascular disease. The strategy will involve detection of abnormal filling behaviour at stress echocardiography, with randomization into longterm and short-term trials to examine various therapeutic strategies. Sensitive new cardiovascular imaging techniques will be used to detect preclinical abnormalities in the structure and function of the heart and vasculature, facilitating a mechanistic understanding of the process of increasing filling pressure with exercise.Read moreRead less

Summary
Cardiovascular disease (CVD) is the major cause of death and disability in Australia and worldwide. This burden will increase without new knowledge. We will address knowledge gaps that delay more effective prevention and control. Our team has a strong track record of influencing clinical practice of CVD prevention, treatment and technology transfer. For many, the first indication of a heart problem is sudden heart attack or death. By understanding mechanisms we aim to develop new tests and treat ....Cardiovascular disease (CVD) is the major cause of death and disability in Australia and worldwide. This burden will increase without new knowledge. We will address knowledge gaps that delay more effective prevention and control. Our team has a strong track record of influencing clinical practice of CVD prevention, treatment and technology transfer. For many, the first indication of a heart problem is sudden heart attack or death. By understanding mechanisms we aim to develop new tests and treatments that prevent heart attack, heart failure and other serious consequences of atherosclerosis.Read moreRead less
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.

Summary
Lung cancer is the most common cause of cancer deaths in men and women in the world and the incidence in Australia is rising with our aging population. Survival rates for lung cancer are very poor. We have discovered a new gene that is produced by lung cancer cells and may contribute to the aggressive nature of this disease. We will investigate this gene to determine if it could be a useful target for new therapies for lung cancer and it determine its utility as a biomarker for the severity of t ....Lung cancer is the most common cause of cancer deaths in men and women in the world and the incidence in Australia is rising with our aging population.
