Long Chain Omega-3 Polyunsaturated Fatty Acids and Heart Health in Humans. The primary aims of the project is to assess the effect of DHA rich tuna oil on cholesterol carrying lipoproteins and to determine a quicker method in assessing someone's omega-3 status. The expected outcomes include the determination of: 1) the most appropriate blood sample and a rapid test and for evaluating the omega-3 status; 2) the minimum dose of tuna oil required which will not only improve a person's omega-3 statu ....Long Chain Omega-3 Polyunsaturated Fatty Acids and Heart Health in Humans. The primary aims of the project is to assess the effect of DHA rich tuna oil on cholesterol carrying lipoproteins and to determine a quicker method in assessing someone's omega-3 status. The expected outcomes include the determination of: 1) the most appropriate blood sample and a rapid test and for evaluating the omega-3 status; 2) the minimum dose of tuna oil required which will not only improve a person's omega-3 status but also improve their plasma lipid profile and hence reduce their overall risk for cardiovascular disease (CVD); and 3) the use of the Omega-3 Index by medical practitioners. The significance is the increased knowledge of the health benefits of DHA rich tuna oil and that a new CVD risk marker will be generally accepted.Read moreRead less

This proposal focuses on translating nanotechnology to ultrasensitive molecular monitoring for biomedicine. We will apply a new tool, amplified fluorophores to proteomics where they will provide an improved method for early detection and understanding of diseases through molecular fingerprints. The project will also generate an ultra-sensitive, rapid technology that can be used for personalized point-of-care diagnostics. The applications can include the detection of disease markers, pathogens or the determination of protein content in a clinical sample. These technologies will be applicable across a spectrum or of diseases all of which will benefit the broader community.Read moreRead less

Chemical synthesis of cancer-associated glycoproteins. Glycosylation of proteins is an extremely common event which plays an important role in a variety of biological processes. Aberrant glycosylation and over-production of glycoproteins is associated with numerous cancer types (including breast, prostate, ovarian and small lung) and are recognised as promising agents for disease diagnosis and vaccine development.

Glycosylation of proteins is an extremely common event which plays an important role in a variety of biological processes. Aberrant glycosylation and over-production of glycoproteins is associated with numerous cancer types (including breast, prostate, ovarian and small lung) and are recognised as promising agents for disease diagnosis and vaccine development. A range of cancer-associated glycoproteins will be synthesised in this research program using a number of novel chemical technologies. These glycoproteins will be used to develop cancer vaccines and diagnostics. Cancer is a severe burden on the Australian community and on the economy, therefore this research will be of significant benefit to Australia.Read moreRead less

Improving the sensitivity and availability of in-vitro immuno-diagnostic tests is a critical goal towards developing real time efficient tools for the detection of infectious diseases, cancers, allergies and auto-immune diseases. The goal is to increase the sensitivity of these tests by reducing background noise that has been a feature of the commonly used ELISA technology. This will be achieved by developing a novel optical integrated waveguide array supporting a large range of distributed tests, including several based on a novel multi-colour detection scheme. This massively parallel approach will underpin a new generation of low-cost, efficient diagnostic tests.Read moreRead less
