Does muscle contribute to the maintenance of vitamin D status in winter? This project aims to test the mechanism by which vitamin D status is maintained in winter when input is low. The long half-life in blood of the vitamin D metabolite, 25-hydroxyvitamin D [25(OH)D], maintains an adequate vitamin D status over winter, when sunlight, which produces vitamin D in skin, is reduced. From preliminary data in sheep and mice, this project proposes that skeletal muscle, not fat, stores vitamin D. This ....Does muscle contribute to the maintenance of vitamin D status in winter?

From preliminary data in sheep and mice, this project proposes that skeletal muscle, not fat, stores vitamin D. This project will test this hypothesis in sheep, cultured muscle cells and in transgenic mice. The project will confirm whether the processes identified in skeletal muscle contribute to the maintenance of vitamin D status, and identify ways of enhancing this process.Read moreRead less

Summary
Hyperpolarised gas functional lung and molecular imaging. This project will produce a polariser to generate magnetised gas for research with magnetic resonance imaging (MRI). This allows imaging of normal and abnormal lung ventilation and circulation in animal and humans. The use of these hyperpolarised gases can also be used to tag specific molecules and increase understanding of lung metabolism.
Microparticles as effectors of microvascular alterations in brain inflammation. Cerebral malaria (CM) kills many children worldwide, but we do not understand why their small blood vessels in the brain become obstructed. We found that tiny elements detached from cell membranes, called microparticles (MP), are dramatically elevated in the blood during CM. Our results strongly suggest that these MP are important in CM development. We have found that some drugs block the release of MP and the stick ....Microparticles as effectors of microvascular alterations in brain inflammation. Cerebral malaria (CM) kills many children worldwide, but we do not understand why their small blood vessels in the brain become obstructed. We found that tiny elements detached from cell membranes, called microparticles (MP), are dramatically elevated in the blood during CM. Our results strongly suggest that these MP are important in CM development. We have found that some drugs block the release of MP and the stickiness of malaria parasites to blood vessels. Our project will tackle the conditions of MP production and define new drugs to prevent it. It also will explain how the brain becomes affected by high numbers of MP. Our results will cast new light on why the brain functions abnormally when its blood vessels become modified.Read moreRead less

Returning WA Rapid Acquisition Fluorescent Microscopy to the cutting edge. The equipment proposal aims to establish West Australia's only super-rapid-speed, high throughput confocal microscopy facility. The technology will provide researchers in biotechnology, medicine, environmental biology and agriculture with contemporary state-of-art opportunities to analyse living cells and/or large-area tissue specimens in three-dimensions with the highest possible speed and high-resolution. West Australia ....Returning WA Rapid Acquisition Fluorescent Microscopy to the cutting edge. The equipment proposal aims to establish West Australia's only super-rapid-speed, high throughput confocal microscopy facility. The technology will provide researchers in biotechnology, medicine, environmental biology and agriculture with contemporary state-of-art opportunities to analyse living cells and/or large-area tissue specimens in three-dimensions with the highest possible speed and high-resolution. West Australia hosts 1 twelve-year old historic rapid-acquisition confocal microscope that is heavily subscribed, no longer manufactured and prone to regular, prolonged, costly breakdowns. Accessing high-speed confocal systems in other states is not a viable option putting WA-based researchers at a significant disadvantage.Read moreRead less
Establishing evidence for the functional properties of a whole grain in weight management. The successful development of functional foods relies on communicating proven effects. This project aims to prove that the food containing the satiety properties of a whole grain (OG) may help in weight management. We will conduct basic research investigating the link between consumption of OG-containing foods and the regulatory mechanisms of satiety, and test whether the satiety properties can be used to ....Establishing evidence for the functional properties of a whole grain in weight management. The successful development of functional foods relies on communicating proven effects. This project aims to prove that the food containing the satiety properties of a whole grain (OG) may help in weight management. We will conduct basic research investigating the link between consumption of OG-containing foods and the regulatory mechanisms of satiety, and test whether the satiety properties can be used to prevent, reduce and correct body weight gain in the early, middle and late stages of obesity. We will then apply this understanding in a human trial of mildly and long term overweight subjects, to aid the formulation of statements on the potential health benefits from consuming OG.Read moreRead less
Vocal Quality, Projection and Perception. This project will quantify the vocal features of projection and loudness in experienced operatic soloists and actors and will examine how these features relate to emotional expression and how each of these qualities are perceived by the performers and by others. We will determine which respiratory and laryngeal techniques are associated with the ability to communicate emotional connection and to produce certain sound qualities, in particular associated ....Vocal Quality, Projection and Perception. This project will quantify the vocal features of projection and loudness in experienced operatic soloists and actors and will examine how these features relate to emotional expression and how each of these qualities are perceived by the performers and by others. We will determine which respiratory and laryngeal techniques are associated with the ability to communicate emotional connection and to produce certain sound qualities, in particular associated with the performer's ability to project a powerful voice unamplified within a large theatre, as well as over an orchestra.Read moreRead less
