Summary
Healing of deep burns, unlike that of superficial injuries, often resolves with scarring. Scarring is reduced with rapid closure of burns. The CIs have discovered and patented novel growth factor complexes that stimulate the growth and migration of keratinocytes, cells derived from skin. Hence these complexes hold therapeutic potential for wounds that require rapid closure such as deep burns. This application will provide pre-clinical, proof-of-principle data to facilitate future patient trials.

Summary
Treatment of infertility using IVF technology has been enormously successful. However, there are major concerns regarding the high incidence of multiple pregnancies (caused by the transfer of more than one embryo) and the potential adverse health outcome of adults conceived from this technology. Multiple pregnancies place both mother and infant at enormous risks, with increased obstetrics care, prematurity, increased neonatal care and neurological disorders such as cerebral palsy.

However, there are major concerns regarding the high incidence of multiple pregnancies (caused by the transfer of more than one embryo) and the potential adverse health outcome of adults conceived from this technology. Multiple pregnancies place both mother and infant at enormous risks, with increased obstetrics care, prematurity, increased neonatal care and neurological disorders such as cerebral palsy. This can be overcome simply by the transfer of a single embryo. However, patient and clinical expectations are that single embryo transfer should be achieved with little to no reduction in pregnancy rate, and currently this is not possible because our methods for culturing embryos are inadequate. Studies in animals suggest that laboratory growth of mammalian embryos can lead to small-for-gestational age babies (even when the effect of multiple births is taken into consideration). This backed by recent studies which agree that babies born from IVF are smaller than expected. This might lead to health problems in later life, as smallness at birth is associated with higher risks of cardiovascular disease and diabetes, especially as age progresses beyond 40 years. However, the oldest IVF child is currently 23 years of age. Previously we have shown that a protein growth factor, called granulocyte-macrophage colony-stimulating factor (GM-CSF), found normally in the reproductive tract, has dramatic beneficial effects on human and mouse embryos grown in the laboratory. Furthermore, we have shown in mice that embryo exposure to GM-CSF alleviates the detrimental side effects of in vitro culture on foetal growth and body structure after birth. Our research is now focussed on understanding why this protein is beneficial to embryo growth and to test if we can increase pregnancy rates and produce normal healthy infants from the transfer of single embryos treated with GM-CSF.Read moreRead less

Summary
Infertility comes at an enormous social and financial cost to Australian society. The aim of this proposal is to improve the success rate of an innovative technology that matures eggs in the laboratory and so eliminates the need for the hormones normally used in IVF. To achieve this a newly discovered egg-secreted protein first has to be produced in the laboratory.

Summary
Infertility comes at an enormous social and financial cost to Australian society; infertility is a major psychological burden on young couples and the technologies used to treat infertility, such as in vitro fertilisation (IVF), require expensive drugs to stimulate the ovary.

The cost of these drugs to Medicare is expected to exceed $100 million p.a. over the next decade. A reproductive technology, which has always shown great potential to elevate some of this burden, is oocyte (egg) in vitro maturation (IVM), which drastically reduces the use-cost of drugs and the stress to patients. However, oocyte IVM has been slow to live up to its potential and the technology is still not in widespread clinical practice, mainly due to disappointing success rates in women. We have been studying oocyte IVM in animals for many years, and have recently made a significant technological breakthrough, improving success rates by ~50%. In this field, a 50% increase in efficiency is substantial and has significant clinical and commercial application. Currently, we are the only group worldwide with this technology. Over the course of this 2-year project we will conduct follow-up experiments to refine this discovery and investigate the feasibility of using this approach to treat human infertility. We are already in negotiations with two medical device manufacturers to licence this technology. We expect that this project will lead to a series of products and technologies that will enter a clinical trial for the treatment of infertility within 2-3 years.Read moreRead less

Summary
Swelling of tissue due to fluid accumulation, known as oedema, is one of the earliest signs of diseases such as kidney failure, burn injury or lymphedema. All of these are not uncommon conditions. Lymphedema, for example, is a common sequela of radiotherapy or surgery in the treatment of malignancies such as breast, uterine, and prostatic carcinoma. It is reported to occur in up to 40% of patients depending on the type of surgery and whether or not the patient received radiotherapy.

All of these are not uncommon conditions. Lymphedema, for example, is a common sequela of radiotherapy or surgery in the treatment of malignancies such as breast, uterine, and prostatic carcinoma. It is reported to occur in up to 40% of patients depending on the type of surgery and whether or not the patient received radiotherapy. It is estimated that at any time 100000 women are suffering from post- mastectomy lymphedema in Australia alone. Treatment of breast cancer alone therefore, given the incidence of the disease, produces a large at-risk population. Add to this other causes of oedema and the magnitude of the problem becomes clearly apparent. The presence of chronic oedema is often a disfiguring and disabling disorder, usually accompanied by pain, recurrent infection, reduced mobility and impaired function. In acute oedema the problem often resolves with recovery from the underlying pathology. In chronic oedema, progression may be arrested by early intervention including complex physical therapy (exercise regimen, compression bandaging, and massage) which is effective in reducing limb volume, in improving the quality of life, function and body image of patients. Although the assessment of oedema is clearly of clinical importance, relatively few objective and accurate techniques for its measurement exist. Research conducted over the past decade by the applicants has pioneered the Use of Bioelectrical Impedance Analysis for the assessment of lymphedema. This study aims to translate this basic research into clinical practice. Sensitivity and specificity studies will establish normative and threshold values for impedance measurements that can be used as presumptive indicators of oedema. User friendly technology and equipment suitable for clinical use will be developed which should improve treatment therapies.Read moreRead less

Summary
Preterm birth (ie birth before the 37th week of gestation) is the most significant problem facing contemporary clinical obstetrics in the developed world and occurs in approximately 5% to 12% of all deliveries. Being born too early is the major cause of perinatal morbidity and mortality. Data from Australia indicate that each year, more than 17,000 babies will be born prematurely. Of these infants, over 10,000 will suffer respiratory complications and about 1300 will die during the first 21 days ....Preterm birth (ie birth before the 37th week of gestation) is the most significant problem facing contemporary clinical obstetrics in the developed world and occurs in approximately 5% to 12% of all deliveries. Being born too early is the major cause of perinatal morbidity and mortality. Data from Australia indicate that each year, more than 17,000 babies will be born prematurely. Of these infants, over 10,000 will suffer respiratory complications and about 1300 will die during the first 21 days of life. The sickest and most premature of these infants require admission to a Neonatal Intensive Care Unit in a tertiary hospital. Aside from the medical implications of premature delivery, there is also a considerable fiscal challenge to society. While treatments for the prevention of labour have improved considerably over the past decade, current screening tests of preterm labour (ie Fetal Fibronectin test) are unreliable and have poor positive predictive values. The principal objective of this project is to develop and deliver a multiplex assay for the prediction and diagnosis of human preterm labour. Through the successful application of our own proteomic discovery programmes using both ovine and human cervico-vaginal fluid samples, we have identified several new protein markers of labour. Having completed this Phase 1 biomarker trial and established proof-of-concept, we are now well positioned to initiate a Phase 2 biomarker trial to determine reliable estimates of assay sensitivity and specificity. This project targets the development of a new diagnostic to meet a recognised market gap. Delivery of such a test will create a new market in pregnancy-based clinical diagnostics and significantly impact on improving health care and quality of life for many preterm babies. Should the project be completed as detailed and mitigate some of the risk of commercial development, it would then be realistic to seek substantial funding from the private sector.Read moreRead less
