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). Infection with certain high risk human papillomaviruses is known to be necessary for the development of cervical cancer.

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
Preterm birth is a major cause of neonatal death and cerebral palsy. This grant will provide proof-of-concept that a computer program can be developed to predict a pregnant woman�s risk of preterm birth. There is a large market (4M US and 8M Europe), there are no competing technologies. This is a unique collaboration between Biomedical Engineering and an Australian centre with an international reputation in preterm birth, assisted by a pathology company.

Summary
Cardiovascular disease (CVD, heart disease and stroke) is the leading cause of death in women aged 65 and over. Counter-intuitively, androgens may be as, or even more important, than estrogens in determining CVD risk and all-cause mortality in women, but this is yet to be verified. We will document blood levels of androgens in women aged 70+ and determine whether androgens are associated with CVD and death in this large cohort of elderly well women.
Alpha-2-Macroglobulin And The Transport And Uptake Of The Hormone, Hepcidin

Summary
Hepcidin is a peptide hormone that is a major regulator of iron metabolism. It has been suggested that hepcidin is free in the blood. However, we recently identified that hepcidin binds with alpha-2-macroglobulin (a2-M) in the plasma and this increases the efficacy of this peptide. The demonstration that a2-M plays a role in hepcidin biology will lead to a better understanding of hepcidin physiology, the development of methods for its measurement and improved treatment of iron related diseases.
Lungfish Paired Fins and the Origin of Limbs as an Evolutionary Novelty. This project will utilise a uniquely Australian animal, the lungfish, to address a hitherto unresolved problem of considerable scientific significance - how a fish fin evolved into a tetrapod (four-legged animal) limb. The Australian lungfish is the most primitive of the four surviving genera of lobe-finned fish and is recognised as the closest living ancestor to the tetrapods. It is listed as 'vulnerable' in its native ha ....Lungfish Paired Fins and the Origin of Limbs as an Evolutionary Novelty. This project will utilise a uniquely Australian animal, the lungfish, to address a hitherto unresolved problem of considerable scientific significance - how a fish fin evolved into a tetrapod (four-legged animal) limb. The Australian lungfish is the most primitive of the four surviving genera of lobe-finned fish and is recognised as the closest living ancestor to the tetrapods. It is listed as 'vulnerable' in its native habitat. Macquarie University, however, has the only captive breeding population of lungfish in the world. We are thus uniquely placed to address critically important questions concerning the evolution of fish into tetrapods. Read moreRead less

Summary
This project will investigate how the human brain processes a number of important aspects of human jaw muscle pain that are clinically relevant but poorly understood. For example, we do not understand why jaw muscle pain has such different behavioural effects to skin pain. Jaw muscle pain is associated with a significant emotional component not seen in with skin pains. Also, skin pain usually has a sharp or burning quality, is well-localized and is readily treated, while jaw muscle pain is a dee ....This project will investigate how the human brain processes a number of important aspects of human jaw muscle pain that are clinically relevant but poorly understood. For example, we do not understand why jaw muscle pain has such different behavioural effects to skin pain. Jaw muscle pain is associated with a significant emotional component not seen in with skin pains. Also, skin pain usually has a sharp or burning quality, is well-localized and is readily treated, while jaw muscle pain is a deep pain that has a dull, aching quality that may be referred to related sites of the face, head and neck. It is also not known why jaw muscle pain is more common in females in comparison to males. Chronic jaw muscle pain is a major symptom of patients with Temporomandibular Disorders, the most common form of non-dental orofacial pain and that involves pain in or about the jaw joint and-or jaw muscles, and often limitation of jaw movement. Chronic jaw muscle pain can have a severe effect on quality of life but its diagnosis and management is difficult. Despite the widespread prevalence of chronic orofacial pains, we have little information on the central processing of chronic human orofacial pain. This proposal will improve our fundamental understanding of how jaw muscle pain is processed in the brain. The way that the central nervous system processes and represents jaw muscle pain will help explain why these pains present differently in the clinic and should provide important information on the differences between females and males in the representation of jaw muscle pain. This information on the central processing of chronic orofacial pain is crucial to inform the direction of novel or specific management strategies. Our long-term goal is to improve the diagnosis and management of patients with Temporomandibular Disorders, and the present application represents a major new direction of research.Read moreRead less
Linking mutant zebrafish phenotypes with their underlying genetic lesions. Zebrafish mutants have been generated with many interesting abnormalities, but to understand these abnormalities, the defective genes must be identified by positional cloning.

Zebrafish mutants have been generated with many interesting abnormalities, but to understand these abnormalities, the defective genes must be identified by positional cloning. We seek to identify the defective genes underpinning four mutants. Mutant #562 develops a normal nervous system which then undergoes rapid degeneration. The mutant flotte lotte has abnormal gut development. Two mutants with defective early blood formation will be studied. We will establish techniques for several steps that will be useful for all zebrafish mapping projects. We expect the genetic characterization of these mutants to provide new insights into nerve cell survival, gut development, and blood formation.Read moreRead less
