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
As women age, the quality of their eggs decline and their chance of having a healthy baby plummets. The accumulation of DNA damage within the egg, and the reduced ability to repair this damage, may be one cause of compromised reproductive success in older women. This project will investigate the ability of eggs to repair DNA damage during maternal aging and will explore the importance of DNA repair to fertility and the transmission of high quality genetic material to their offspring.

Characterisation Of Eurl, A Novel Gene Implicated In The Etiology Of Abnormal Brain Development And Intellectual Disability

Summary
Intellectual disability affects around one per cent of Australians, and can arise from genetic abnormalities during fetal life, such as through abnormal regulation of gene expression. We have identified a novel gene, known as eurl, which controls brain assembly as well as the ability of neurons to form functional connections within the brain. We will investigate how this novel gene controls brain development, and characterise eurl as a potential therapeutic target for learning and memory.
Investigating A Theoretical Model Of Cognitive Control In Children With Attention Deficit Hyperactivity Disorder (ADHD): Informing Our Approach To Cognitive Training.

Funding Amount

Summary
ADHD is the most common childhood developmental disorder, characterised by inattentive and/or hyperactive behaviours. Cognitive control has been highlighted as a potential mediator of ADHD symptoms. This program will i) delineate the relationship between cognitive control and ADHD symptoms, ii) develop a cognitive training intervention to target the underlying mechanisms identified as mediators of ADHD symptoms and iii) evaluate the program in a gold-standard clinical trial.
Regulation Of Neural Progenitor Cell Self-renewal By The RNA-binding Protein ZFP36L1 During Development And Disease

Funding Amount
$345,401.00
Summary
The timely differentiation of neural stem cells is critical during development, and the unrestrained proliferation of neural stem cells in the adult can lead to deadly brain cancers such as glioma. At present our understanding of the key molecules that regulate neural stem cell behaviour during these processes remains limited. In this proposal we will investigate the molecular determinants underpinning neural stem cell biology, both within the developing brain, and within glioma.
Early career teacher induction: Supporting precarious teachers.

This project aims to investigate the ways in which Australian induction policies support precariously employed early career teachers to effectively manage student classroom behaviour. This project expects to generate new knowledge of workforce development and induction experiences of early career teachers employed on casual and short-term contracts. Expected outcomes of this project include alternative policy and practice recommendations to support the transition of insecure replacement teachers within the profession. The benefits of this research include, improving teachers’ classroom management practices; the retention of new teachers; improving teacher workforce development; and building a healthier education system.

Investigating the effectiveness of teacher education for early career teachers in diverse settings: a longitudinal study. This project investigates the effectiveness of teacher education programs in Victoria and Queensland in preparing teachers for the variety of school settings in which they begin their careers. The findings will inform state and national policy, as well as the work of professional regulation authorities and teacher education providers.

The mucosal surfaces are the entry site for many pathogens (eg. cholera, rotaviruses, helicobacter, SARS and sexually transmitted diseases including HIV infections). The ideal vaccine would elicit both systemic and mucosal immune response, enhancing immunity at this first line of defence.

The ideal vaccine would elicit both systemic and mucosal immune response, enhancing immunity at this first line of defence. The oral route has formidable barriers to antigen uptake such as digestive enzymes, commensal microbes, mucous layers and gastric acid. Our strategy targets the vascular addressin found in immune tissues of the gut (called MAdCAM) so that the vaccine is linked to an antibody against MAdCAM. Thus for the first time we believe that a parenteral vaccine ie. injected im or iv (bypassing the oral barriers) can induce mucosal immunity.Read moreRead less
Intercultural understanding in primary and secondary schools. What facilitates or impedes intercultural understanding in children, adolescents and schools? How can this be addressed? How can we know what makes a difference? This project answers these questions at the individual, school and national level using a novel cultural systems approach and methodological and technological innovations.
