Summary
The Polycystic Ovary Syndrome (PCOS) affects up to 10% of women of reproductive age, which translates into around 350,000 women in Australia. It is the most common hormonal disorder in women. The syndrome has far-reaching adverse implications for general and reproductive health, including menstrual disorder, obesity, infertility, miscarriage, pregnancy complications, increased risk of diabetes and possibly heart disease. PCOS also commonly causes cosmetic problems such as excess body hair and ac ....The Polycystic Ovary Syndrome (PCOS) affects up to 10% of women of reproductive age, which translates into around 350,000 women in Australia. It is the most common hormonal disorder in women. The syndrome has far-reaching adverse implications for general and reproductive health, including menstrual disorder, obesity, infertility, miscarriage, pregnancy complications, increased risk of diabetes and possibly heart disease. PCOS also commonly causes cosmetic problems such as excess body hair and acne. The underlying causes of PCOS are not known but are thought to arise during intrauterine (fetal) life and to be modified by aspects of childhood health, particularly overweight and obesity. Using a large and well established cohort of adolescents followed up since fetal life and throughout childhood and currently aged 13-15 years old (the Raine cohort), we will define for the first time the intrauterine and early childhood correlates of PCOS. PCOS will be diagnosed by a specialist gynacologist using current international criteria. We will then utilise extensive existing data from this cohort combined with new measurements on existing samples to determine the contribution of key factors including fetal growth restriction, low birth weight, fetal androgen exposure, rapid postnatal growth, childhood adiposity, elevated fasting glucose and insulin and age at menarche to PCOS. In this way, we will address for the first time the hypothesis that PCOS arises as a result of events during fetal life and is affected by factors during childhood. The results from these studies will improve our understanding of PCOS and eventually improve reproductive and metabolic health for a substantial population of women internationally. It is essential that these studies are conducted as soon as possible or the opportunity will be missed. Girls with persistent menstrual irregularity are likely to be commenced on hormonal treatments which will make the diagnosis of PCOS impossible.Read moreRead less

Summary
Waste recycling is a normal process through which cells clear unwanted material to maintain good health. There are some conditions that are associated with impaired waste recycling in cells (such as dementia), which make this process relevant to lifelong health. We have developed a new test that will, for the first time, enable accurate measurement of the recycling process 'in action' in humans, and may identify people who have poor cellular health.
Limbic Maturational Changes In Adolescence And Young Adulthood (LIMCA) - A Longitudinal Study

Summary
Structural and cognitive changes of the limbic regions have been linked to number psychiatric disorders. A thorough understanding of the dynamics of healthy maturation of these brain areas with age is necessary. The main aim of this research is to longitudinally study and model the neuro-developmental changes of the limbic region during adolescence and young adulthood. These will provide an invaluable template in identifying deviant patterns of limbic development in children with neuropsychiatri ....Structural and cognitive changes of the limbic regions have been linked to number psychiatric disorders.

Summary
Members of the family of enzymes known as glutathione transferases are known to be responsible for the metabolism and detoxification of a wide range of compounds including therapeutic drugs and cancer causing chemicals. Genetic variation in an individual's compliment of glutathione transferases can alter their response to drug treatment or their susceptibility to cancer.

Genetic variation in an individual's compliment of glutathione transferases can alter their response to drug treatment or their susceptibility to cancer. The Omega class of glutathione transferases are important because they are involved in the metabolism of arsenic and because they have been shown to influence the age-at-onset of both Alzheimer s and Parkinson s diseases. The present studies will investigate the structure and function of different Omega class glutathione transferases and determine how they interact with arsenic based drugs. These studies will attempt to determine why the toxicity of arsenic varies between individuals and aims to prevent adverse reactions to arsenic containing drugs used in cancer therapy. These studies will also investigate the mechanism by which the inheritance of certain forms of Omega class glutathione transferase can affect the age at-onset of Alzheimer s disease and Parkinson s disease. The understanding of this mechanism may provide the basis for a therapy that could delay or prevent the onset of these common diseases.Read moreRead less
