Summary
Embryo-based biotechnologies have the potential to improve human reproductive health, notably in treating infertility by In vitro fertilisation (IVF). They are also central to the future use of embryonic stem cells for human tissue replacement. This project investigates the molecular mechanisms controlling one of the earliest differentiations in the growth of the embryo.

They are also central to the future use of embryonic stem cells for human tissue replacement. This project investigates the molecular mechanisms controlling one of the earliest differentiations in the growth of the embryo. Using the mouse as an experimental model it will investigate the importance of several factors in the changes which set up the placenta and fetus as seperate tissues in the very early embryo. A key focus is the supply of glucose to the newly fertilised embryo and how important this glucose supply is for the survival of the embryo. Moreover there is great interest in the possibility that metabolic events in utero can contribute to the development of diseases in later life, notably, coronary heart diease, stroke, high blood pressure and non-insulin dependent diabetes. The results from these studies will contribute to our understanding of why some couples are infertile, lead to improved management of infertility by diet and invitro fertilisation procedures. It will also be of benefit in dietary advice to women with diabetes mellitus, seeking to have children. The adenoviral strategy for gene delivery into early mouse embryos may in the long term also find wide clinical application in the treatment of genetic defects at the very earliest stages in development and as such is of enormous potential benefit in the management of both animal and human reproduction.Read moreRead less
A Media Formulation To Improve Implantation Rates And Pregnancy Outcome Following ART

Summary
Since women are delaying childbearing, ART is increasingly required. 2-3% of births in Australia follow ART. Only 15-40% of embryo transfers in assisted reproduction (ART) result in ongoing pregnancies. The poor success rate is due to the fact that the embryo culture media bear no resemblance to the maternal environment in which they grow normally. The new culture media to be validated in this proposal includes factors that are critical for embryo implantation and will improve ART success.
Osteal Macrophages As Therapeutic Targets For Fracture Repair

Funding Amount

Summary
Fragility fracture associated with osteoporosis is a substantial health problem costing $1.62 billion to treat in 2012 in Australia. There is no approved therapy to improve and accelerate fracture healing to help reduce this increasing health burden. This research will advance understanding of fracture repair in healthy and osteoporotic bone and progress development of a fracture therapy to improve bone repair by promoting specialised immune cells.
Protecting Synaptic Connectivity In Alzheimer's Disease

Summary
In Alzheimer’s disease, connections between neurons (synapses) are progressively damaged. The BACE inhibitor class of drugs entering Phase III clinical trials may slow the pace of neurodegeneration in patients with dementia. However, these drugs may simultaneously have negative effects on synapse function, learning and memory. This study will assess the effect of BACE inhibition on synapse properties and cognition and identify the contribution of key proteins affected by this treatment.
New Insights Into The Mechanisms Of Thrombogenesis In Atrial Fibrillation

Summary
Atrial fibrillation (AF) is the most common heart rhythm disturbance (arrhythmia), which is associated with a high risk of stroke due to clot formation within the left atria. At present we still only have a limited understanding of the mechanism of clot formation in AF. The aim of this study is to determine the critical mechanisms that contribute to clot formation within the left atria in AF. This knowledge is fundamental to the development of more successful interventional approaches.
