Funding Amount
$831,581.00
Summary
Early adolescence is a critical period in the life of people with asthma. Some children grow out of their asthma and others acquire the disease for the first time. There are important sex differences in the pattern of change. We believe these changes are related to the passage through puberty. This study will examine changes in the features of asthma and allergy during this period and their relation to early life and current environmental exposures.

Summary
Anxiety disorders [e.g., Post Traumatic Stress Disorder (PTSD)] are the most prevalent type of psychopathology in the industrialised world. They are associated with characteristic behavioural (e.g., heightened startle) and autonomic (e.g., cardiovascular) reactions. These disorders are often characterised as an inability to regulate the emotion of fear. Significant progress has been made in understanding the neural and cellular processes involved in the establishment of fear memories, but relati ....Anxiety disorders [e.g., Post Traumatic Stress Disorder (PTSD)] are the most prevalent type of psychopathology in the industrialised world. They are associated with characteristic behavioural (e.g., heightened startle) and autonomic (e.g., cardiovascular) reactions. These disorders are often characterised as an inability to regulate the emotion of fear. Significant progress has been made in understanding the neural and cellular processes involved in the establishment of fear memories, but relatively little is known about the mechanisms by which fear memories can be inhibited or suppressed. Understanding this latter process is a key to the development of effective treatments for anxiety disorders such as PTSD where the patient suffers from persistent, intrusive, unwanted trauma memories. A common experimental procedure for reducing learned fear is to repeatedly expose the subject to a fear-eliciting stimulus but without any aversive outcome. This procedure leads to a progressive loss, or extinction, of the fear reactions elicited by the stimulus. Historically, the extinction of fear was thought to be due to an erasure of the fear memory. However, recent evidence shows that extinction inhibits, rather than erases, the fear memory. Because the fear memories remain intact, some structure(s) in the brain must inhibit activity in the fear pathway. This project uses extinction of conditioned fear reactions in rat subjects to determine the structure(s) in the brain that inhibit fear memories and their behavioural and cardiovascular expression. It brings together the expertise of four well-established researchers and uses a combination of behavioural, physiological, immunohistochemical, tract tracing, and lesion approaches to achieve this aim. The proposed experiments will reveal the structure(s) in the brain that control the inhibition of fear, as well as the site(s) of this inhibition in the fear pathwayRead moreRead less
Using Health Economics To Strengthen Ties Between Evidence, Policy And Practice In Chronic Disease

Funding Amount
$1,925,648.00
Summary
There is a major shortage of researchers with health economics expertise in Australia. This grant will provide training and development for a team of health economists to research chronic diseases covering issues such as: What is the value for money from investment in different treatments? How do such diseases affect the economic circumstances of families? How do we ensure that strategies to address illness work in practice and can be sustained? How do these issues get put on the policy agenda?
Therapeutic Implications Of A Molecular Link Between Survivin And Telomerase Reverse Transcriptase

Funding Amount
$547,970.00
Summary
A unifying feature of all types of cancer cells is that they are immortal. Our investigations will build upon our recent results that showed the gene survivin is involved in cancer cell immortalisation. We will characterise a molecular link between survivin and the enzyme telomerase, which is central to cancer cell immortality. Furthermore, we will demonstrate the therapeutic potential of turning off both survivin and telomerase as a novel approach to halting the growth of cancer cells.

Summary
Indigenous Australians in remote communities are less healthy and more socially disadvantaged than other Australians. This influences the quality of the intrauterine environment. Babies often suffer malnutrition and recurring infections during infancy which are exacerbated by their less than optimal birth status and contribute to chronic conditions (diabetes, cardiovascular disease, renal failure) in adulthood.

This influences the quality of the intrauterine environment. Babies often suffer malnutrition and recurring infections during infancy which are exacerbated by their less than optimal birth status and contribute to chronic conditions (diabetes, cardiovascular disease, renal failure) in adulthood. Existing health services are costly to Government and do not achieve their potential for promoting health and providing quality care. Evidence suggests redesigned models based on continuity of care, focused, proactive family support and workload reform will improve maternal and infant outcomes. New models need to be developed, costed, implemented and evaluated providing governments with the evidence base to initiate service improvement. Such models will have applicability elsewhere in Australia. Professor Lesley Barclay and her team of researchers from Charles Darwin University will conduct research into developing such a model. The project aims to improve the quality of care for remote dwelling Aboriginal women and infants in the year before, during and the year after birth by providing evidence for, and facilitating changes to, service delivery. This will enhance the potential for the development of resilience and well-being of their children. It will also test if service improvements can improve the health of women and reduce childhood disease and therefore reduce the impact of health conditions occurring in adulthood which have their origins in the early stages of life.Read moreRead less

Summary
Cervical cancer is one of the leading causes of cancer death in women internationally. About 15,000 women are detected in NSW annually as having pre-invasive cervical cancer (cervical intraepithelial neoplasia (CIN) grade I, II or III).

About 15,000 women are detected in NSW annually as having pre-invasive cervical cancer (cervical intraepithelial neoplasia (CIN) grade I, II or III). Infection with certain high risk human papillomaviruses is known to be necessary for the development of cervical cancer. In addition, recent long term exposure to smoking and to hormonal contraception are two new factors considered as independent risk factors for the disease. Hormone replacement therapy (HRT) preparations taken around the menopause are a similar composition to hormonal contraceptives, (oestrogen and progestogen), therefore women on HRT may also be at increased risk. No comprehensive study exists internationally to measure the relative importance of these exogenous hormones on the development of pre-invasive cervical cancer in a way that is of public health relevance (e.g. recent long-term use of oral contraceptives and time since stopped, and among smokers and non-smokers). No Australian data are available on the proportion of women who are current users of hormonal contraceptives or HRT. No local prevalence data on the major high risk HPV subtypes (e.g. 16, 18, 33, 45) are available for Australia to describe its distribution and to inform the cervical screening program and future vaccine initiatives. The NSW Pap Test Register holds the screening history of all women on the cervical screening program, hence this is an ideal source for recruiting a representative sample into a study. We wish to conduct a large study of ~2600 NSW women using the NSW Pap Test Register to measure the relative importance of hormones, smoking and HPV infection on the development of CIN II or III.Read moreRead less
