Current medical therapies are insufficient or associated with side-effects and many women instead choose surgery (hysterectomy). The overall aim of our research is to elucidate the molecular mechanisms responsible for heavy menstrual bleeding and to determine how medical therapies can be better directed at individual women.Read moreRead less
Pesonalised Risk Prediction For Severe Treatment-related Gastrointestinal Toxicity In Paediatric Cancer Patients Using Pre-treatment Gut Microbiome Analysis

Funding Amount

Summary
The gut is home to trillions of good and bad bacteria, critical to human health. Each person has a different balance of bacteria, unique to their gut, which shapes their immune system and susceptibility to disease. I will investigate how the unique gut bacteria, in children with blood cancer, can be used to predict which children will develop severe gut side effects (diarrhoea) from their chemotherapy. This will identify high-risk children, enable personalised treatment and improve survival.

Summary
Menstrual bleeding problems are a common cause of pain and discomfort for women and often are satisfactorily treated only by hysterectomy. Despite this, little is known about the processes causing menstruation. Recently, we and others have demonstrated a role for a family of biological catalysts (enzymes) which break down the structure of the tissue lining the uterus (the endometrium) and are thought to cause menstrual bleeding. However, the mechanisms regulating their production during the norm ....Menstrual bleeding problems are a common cause of pain and discomfort for women and often are satisfactorily treated only by hysterectomy. Despite this, little is known about the processes causing menstruation. Recently, we and others have demonstrated a role for a family of biological catalysts (enzymes) which break down the structure of the tissue lining the uterus (the endometrium) and are thought to cause menstrual bleeding. However, the mechanisms regulating their production during the normal menstrual cycle is still largely unknown. Cells which come initially from the blood (leukocytes, particularly neutrophils and eosinophils) dramatically increase in numbers immediately prior to menstruation and these along with other cells, known as mast cells, start to produce a number of factors which we postulate are important for regulation of the enzymes. These cells, are also present in high numbers in endometrium of women with menstrual bleeding problems. This study will demonstrate that both the enzymes, and the leukocytes play a critical role in menstruation and will determine how the leukocytes in the endometrium are regulated. The studies have important implications for understanding and treating menstrual bleeding disorders.Read moreRead less
Negative Symptom Formation In Schizophrenia: An Electrophysiological, Neurophysiological And Computational Modelling Investigation

Funding Amount
$374,508.00
Summary
The Negative and cognitive symptoms of schizophrenia have been recognised as being just as disabling as the more widely recognised positive symptoms such as hallucinations and delusions. Recently it has been proposed that negative symptoms in schizophrenia might be caused by alterations in learning from rewards and punishments. This project will investigate brain activity in people with schizophrenia during reward and punishment based learning tasks while applying computational modelling.
Pubertal Timing, Brain Development And Mental Health In Adolescence

Summary
Early timing of puberty is known to be associated with future mental health problems. This study aims to investigate whether children who go through adrenarche (an earlier phase of maturation) early are at risk for poor mental health during adolescence, and whether abnormal brain development is responsible for linking early adrenarche and mental health outcomes. The results of this research will have implications for the early detection of children at risk for mental health problems.
Protecting The Gut: A Novel Therapeutic Avenue For Reducing The Damaging Consequences Of Obesity

Funding Amount
$570,205.00
Summary
Most patients with obesity develop gut dysfunction. Symptoms including constipation and diarrhoea often present before other common comorbidities like diabetes and heart disease, suggesting that early pathology in obesity may begin in the gut. This research project aims to understand the mechanisms through which gut dysfunction develops in obese mice and human patients, and test a clinically approved compound that has demonstrated gut protective properties for the first time in obesity.
Mood Regulation Using Music: A Community Health Strategy For Improving Quality Of Life In People With Mild Dementia
Funder

Funding Amount
$601,540.00
Summary
This research aims to improve quality of life in people with dementia via community-based strategies for managing depression using music. The impetus comes from my prior research which shows that depression affects both the way people use music and its impact on the listener, a factor not considered in previous studies. Findings will lay the ground for development of an online tool for promoting effective self-regulation of mood with music for use by patients and caregivers in multiple settings.
