Summary
This study will investigate the role of fatty acids (lipids) in schizophrenia. Studies in blood cells and in the brains of patients with schizophrenia have shown that these lipids and related products are altered in schizophrenia. We are now able to measure separate lipid metabolites in the living human brain using a technique called magnetic resonance spectroscopy.

Studies in blood cells and in the brains of patients with schizophrenia have shown that these lipids and related products are altered in schizophrenia. We are now able to measure separate lipid metabolites in the living human brain using a technique called magnetic resonance spectroscopy. Until recently it was only possible to assess lipid metabolites as a group, limiting interpretation. Thanks to a newly available imaging system at the Brain Imaging Research Institute and a new analysis technique, we will be able to measure single lipid metabolites in the living human brain. Simultaneously we will also measure lipids and related enzymes in red blood cells that are responsible for the regulation of these lipids. Preliminary data has shown that there is a strong correlation between these two measures. Furthermore we will investigate the genes that are responsible for the production of these enzymes. By repeating the same tests after 12 weeks we hope to understand how the newer antipsychotic drugs act. Two easy clinical tests (a skin and breath test) will help us to implement the findings in daily clinical practice (diagnostic markers for patients at risk) . With such a multi-level approach we hope to contribute to a new understanding of the origins of schizophrenia going beyond the traditional concepts. The findings might also have direct implications for treatment. Preliminary results are very promising but also contradictory. Therefore it is even more important to carefully investigate the role of these lipids in schizophrenia.Read moreRead less
The Optimization Of Rapid Diagnostic Tests (RDTs) For Malaria

Funding Amount
$44,934.00
Summary
The ability to reliably diagnose malaria infections is key to both the management of individual patients as well as public health efforts to control the disease. Current Rapid Diagnostic Tests (RDTs) for malaria have unacceptable sensitivity. The project will determine the low sensitivity of current malaria RDTs available on the market and help produce a malaria RDT with higher sensitivity and stability. This will bring great health benefits to millions of people.
Development And Prototype Manufacture Of A High-throughput CD4 T-cell Test For Management Of HIV/AIDS Infections

Funding Amount
$163,150.00
Summary
CD4 T-cells are the target of HIV-AIDS infection, and monitoring of HIV-infected patients for these cells is an essential part of disease management. Current CD4 testing methods rely on expensive equipment and reagents and high levels of training, or else they have low throughput that limits their use. This project will develop a standard laboratory assay method for testing CD4 T-cells, increasing the access of patients to CD4 testing, and to HIV therapy, worldwide.

Summary
Our aims are to save the $10 million spent on inappropriate investigations in TBMN each year by the Australian community; to identify and treat individuals with TBMN at risk of renal impairment in order to delay the onset of kidney failure; to understand the underlying disease mechanisms in order to develop specific treatments; and to contribute to the development of a diagnostic assay for TBMN that flags mutations associated with renal impairment and includes a screening test for modifying gene ....Our aims are to save the $10 million spent on inappropriate investigations in TBMN each year by the Australian community; to identify and treat individuals with TBMN at risk of renal impairment in order to delay the onset of kidney failure; to understand the underlying disease mechanisms in order to develop specific treatments; and to contribute to the development of a diagnostic assay for TBMN that flags mutations associated with renal impairment and includes a screening test for modifying genes. The proposed project will change the practice of clinicians by providing evidence for our clinical definition of TBMN and reduce the need for renal biopsies and other investigations thus saving the Australian community up to $10 million annually. demonstrate that a peripheral retinopathy distinguishes between TBMN and X-linked Alport syndrome. This will be a major advance in the diagnosis of Alport syndrome too. determine how often individuals with persistent haematuria who have proteinuria >500 mg-day or renal impairment actually have TBMN. identify the genetic risk factors for renal impairment in TBMN in both the genes directly responsible for TBMN as well as in the modifying genes. determine the mechanisms by which genetic mutations and modifying genes in TBMN cause disease and predispose to renal impairment. Understanding these mechanisms is the first step in the development of specific treatments.Read moreRead less

Summary
This project aims to produce Quality Assurance (QA) algorithms to ensure accurate diagnosis of highly pathogenic avian influenza (HPAI) using serological and molecular techniques.

The project will assess HPAI diagnosis accurately within the setting of other circulating respiratory illnesses, utilising a new HPAI module, ,in combination with existing modules within the Royal College of Pathologists of Australia (RCPA) Serology Quality Assurance Program (SQAP). This will ensure rapid, cost-efficient improvements in diagnostics by utilizing existing infrastructure. The key elements of the project are: Introduction of quality assurance processes to ensure accurate diagnosis and to evaluate existing and developing laboratory testing procedures, test accuracy, and result interpretation; Involvement of human and veterinary laboratories in the QA and development processes; Production of suitable antigenic material through molecular virology as targets for HPAI antibody and molecular diagnostics in QA programs. This will thereby allow large quantities of non-infectious material for HPAI QA assessment of serological and molecular assays around Australia, using baculovirus expressed antigens and cloned gene targets respectively. These projects are designed within a short (<12 month) time frame in order to fulfil the needs of the Australian community in controlling the developing HPAI avian pandemic, and the possible human pandemic. Significant positive outcomes in the next six months are assured by the existence of current QA processes, experience in influenza research already available in the human and animal health laboratories involved, the research records of the groups, and the close existing linkages between the research, QA, diagnostic and avian virology groups.Read moreRead less
