Identifying tear lipids, their deposition onto contact lenses and their role in the development of dry eye. Lipids provide a critical layer in the human tear film that retards evaporation and helps nourish and protect the eye. We will identify the molecules within this essential "oil slick" to better understand dry eye syndrome and the discomfort associated with wearing contact lenses. This may lead to new treatments for dry eye and novel technologies that provide greater comfort for the ~120,00 ....Identifying tear lipids, their deposition onto contact lenses and their role in the development of dry eye. Lipids provide a critical layer in the human tear film that retards evaporation and helps nourish and protect the eye. We will identify the molecules within this essential "oil slick" to better understand dry eye syndrome and the discomfort associated with wearing contact lenses. This may lead to new treatments for dry eye and novel technologies that provide greater comfort for the ~120,000 Australians who wear contact lenses. This collaborative research directly supports the mission of a respected non-profit organisation (Institute for Eye Research) and will train scientists in world-leading analytical technologies that are essential to Australia's emerging biotechnology industries.Read moreRead less

Summary
Unique, state-of-the-art lipidomics infrastructure. The new technologies provided through this grant will significantly enhance our understanding of lipids and their role in normal cell biology and disease. These new insights will be vital in improving our understanding of lipid-related disorders such obesity, type 2 diabetes and cardiovascular disease and helping to improve their treatment and prevention.
Lipidomics Associated with Metabolic Syndrome, Aging and Metabolic Variation between Species. The aim is to apply state-of?the-art mass spectrometry to identify and quantify alterations in membrane lipidomes (i.e. lipid classes, molecular species, structure alterations and by-products) related to two major health problems facing Australia i.e. the Metabolic Syndrome and an Ageing population plus insight into the variation in metabolic rate between organisms. This research offers the opportunity ....Lipidomics Associated with Metabolic Syndrome, Aging and Metabolic Variation between Species. The aim is to apply state-of?the-art mass spectrometry to identify and quantify alterations in membrane lipidomes (i.e. lipid classes, molecular species, structure alterations and by-products) related to two major health problems facing Australia i.e. the Metabolic Syndrome and an Ageing population plus insight into the variation in metabolic rate between organisms. This research offers the opportunity for the development of mass spectrometry based technologies for the early clinical diagnosis of metabolic disorders plus provides a template of information for our Linkage partner (AstraZeneca) to develop pharmaceutical therapies targeting key molecular lipid species identified as critical to particular membrane functions.Read moreRead less
Development of ozone-induced dissociation for lipidomics workflows. An Australian invention (ozone induced dissociation) will be developed in collaboration with a major instrument manufacturer. This project will provide Australian researchers with unique capabilities to investigate the role of lipids (fats) in human disease and will place them at the forefront of lipid research internationally.
New laser and mass spectrometry-based tools for comprehensive structural elucidation of lipids and their biomolecular interactions. Lipid-related disorders such as obesity, diabetes and heart disease are reaching epidemic proportions. We propose the development of specialised instrumentation to identify and quantify lipids (fats) in tissue and culture samples thus providing Australian scientists with unique capabilities to investigate the mechanisms of disease.

Summary
Multiplexed capabilities for surface analysis and imaging by mass spectrometry. This facility will support research aimed at developing rapid and reliable analytical methods for the detection of chemicals directly from biological and man-made materials. The mass spectroscopy methods used at the facility will reveal molecular-level changes in systems ranging from the lens of the human eye to Colorbond steel® and have applications in the detection of chemical and biological hazards.
Developing next generation technologies for unmasking the lipidome. Recent discoveries suggest that the number and structural variety of lipids in nature may be far greater than previously imagined. This complexity arises from the presence of structurally similar, but functionally distinct, lipid isomers that are not readily distinguished using current lipidomics technologies. This project aims to develop unique instrumentation that combines ion mobility and mass spectrometry to enable the rapid ....Developing next generation technologies for unmasking the lipidome. Recent discoveries suggest that the number and structural variety of lipids in nature may be far greater than previously imagined. This complexity arises from the presence of structurally similar, but functionally distinct, lipid isomers that are not readily distinguished using current lipidomics technologies. This project aims to develop unique instrumentation that combines ion mobility and mass spectrometry to enable the rapid separation, identification and quantification of isomeric lipids. These next generation technologies will be deployed in the hope of unmasking the molecular diversity within the lipidomes of two important mammalian cell types, thus providing fundamental new insights into the structure and function of lipids within living systems.Read moreRead less
