The kidneys of infants born preterm continue to develop after birth. However, preterm infants are exposed to high oxygen levels which may impact on ongoing development. In a rodent model of oxygen exposure, the blood vessels of the kidney and the numbers of stem cells will be assessed; additionally, further stem cells will be administered in order to try and prevent any impairment. It is expected that the findings of this study will help to explain the effects of preterm birth on the kidney.
Sperm Methylation Status Predicts Embryo And Pregnancy Outcomes In Male Obesity

Summary
The incidence of male obesity in reproductively age men is epidemic and continually rising with close to 70% of men of reproductive age classified as overweight or obese. Male obesity is not only associated with sub fertility but also changes to pregnancy outcomes and influencing child health. This project will try to uncover the molecular changes in sperm, providing potential mechanisms for the abnormal foetal and pregnancy health seen as a result of male obesity.
Identifying And Preventing Inflammation-induced Brain Injury In Preterm Infants

Summary
Exposure to infection/inflammation around the time of birth is one of the most common factors associated with long-term disability. There is no effective treatment. My studies will use world-class techniques for measuring brain structure and function to improve our understanding of how infection/inflammation impacts on development of the preterm brain and determine whether blocking key inflammatory pathways in the brain will help restore normal brain growth and development in preterm infants.
The Consequences Of Innate Anti-viral Effector Responses On Reproductive Outcomes In Placental Mammals

Summary
The mother's immune system can tolerate the growth of an ostensibly foreign fetus during pregnancy. We will investigate whether exposure to viral infections either just before or during pregnancy can result in reduced fertility and whether it may affect fetal growth and development. These results will contribute in designing effective interventions to limit any potential detrimental outcomes.
Translating Advances In Cell-free Fetal Nucleic Acids Into Better Perinatal Care

Summary
My overall aim is to translate advances in biotechnology into better care for pregnant women. My first aim is to study brain development by analyzing the fluid that surrounds the unborn baby. This work may provide more information to women about their baby’s expected outcome. My second aim is to evaluate the impact of new DNA technologies on the detection of genetic conditions in the baby before birth. This work will confirm if this new generation of tests is fulfilling our high expectations.
Improving Neurodevelopmental Outcomes Of Preterm Infants

Summary
In Australia over 20,000 babies are born preterm each year. Preterm babies are at risk of long term developmental problems including movement, learning and behavioural impairments. This research will examine both neurodevelopment and brain development of very preterm (born <30 weeksÍ gestation) and late preterm (32-36 weeksÍ gestation) babies from birth to into early childhood so that we can understand how gestational age at birth relates to development, brain growth and interventions.
Creatine Supplementation In Pregnancy: Utilising Cells’ “Built-In” Energy Buffering System

Funding Amount
$318,768.00
Summary
Through pregnancy, the placenta transfers oxygen and nutrients from the mother to the baby. When a placenta doesn’t function properly a baby’s health is compromised. This can lead to morbidity or death. Creatine is the “back-up generator” of all cells and could help the failing placenta increase nutrient and oxygen delivery to the baby. This study will develop creatine as a potential new therapeutic, to improve the survival of babies of complicated pregnancies.
Improving The Fetal To Neonatal Transition In Compromised Newborns; Towards Better Outcomes For Babies Born Too Soon Or With Under-developed Lungs

Funding Amount

Summary
The birth of a compromised infant affects 13 million pregnancies worldwide annually and is the greatest cause of neonatal death, disability and chronic disease. I will identify mechanisms to greatly improve the fetal to neonatal transition in premature babies and babies with under-developed lungs. This research is urgently required to provide the necessary evidence to target interventions in the delivery room to reduce the short- and long-term burden of disease in compromised newborns.
Novel Molecular Pathways Of The Placental Renin Angiotensin System In Preeclampsia

Funding Amount

Summary
Preeclampsia (PE) is a common and potentially life-threatening pregnancy disorder of pregnancy which originates in the early placenta. We will look into new interactions between molecules that determine how early cells establish a functioning placenta. Detection and early treatment of abnormal placental function can prevent PE before serious complications develop.
The Potential Of Cord Blood Stem Cells To Reduce Neuroinflammation

Funding Amount

Summary
Cerebral palsy (CP) is the most common cause of physical disability in children and it is well recognised that the brain injury that underlies CP occurs during pregnancy or around the time of birth. Stem cells isolated from umbilical cord blood offer a promising new therapy for children with CP. This proposal will explore the mechanism of how cord blood stem cells can reduce brain inflammation and damage caused by hypoxia-ischemia, an event known to lead to cerebral palsy.
