Neuroimaging changes underpinning improvements in cognition in the elderly. Natural supplements are often used to improve brain and cognitive function, however, we do not know how these supplements work in the brain. Using novel brain imaging scans, the project will investigate whether 12-month administration of two promising natural supplements improves brain markers of ageing and cognitive decline in an elderly population.
How eating patterns interact with activity, sleep and mood. This project aims to understand temporal eating patterns (the timing and distribution of food intake and eating occasions across the day) among adults and how these eating patterns interact with activity and sleep patterns. Eating, activity and sleep patterns form a lifestyle triad which may be important for well-being and productivity. The project will study eating, activity and sleep patterns in daily life, to examine their social dri ....How eating patterns interact with activity, sleep and mood. This project aims to understand temporal eating patterns (the timing and distribution of food intake and eating occasions across the day) among adults and how these eating patterns interact with activity and sleep patterns. Eating, activity and sleep patterns form a lifestyle triad which may be important for well-being and productivity. The project will study eating, activity and sleep patterns in daily life, to examine their social drivers, interactions and effect on mood. This project could enable these behaviours to be targeted, with the potential to promote healthy lifestyles and improve health, quality of life and productivity.Read moreRead less
Identification of Australian-bred apple and plum varieties with enhanced health attributes. Improved prevention could save Australia $4 billion annually in health care costs, mainly in the area of cardiovascular disease. A higher flavonoid intake has been estimated to reduce the risk of cardiovascular disease by about 20%. Apples are important sources of flavonoids in the diet.

Improved prevention could save Australia $4 billion annually in health care costs, mainly in the area of cardiovascular disease. A higher flavonoid intake has been estimated to reduce the risk of cardiovascular disease by about 20%. Apples are important sources of flavonoids in the diet. The proposed project involves collaboration between the Department of Agriculture and Food Western Australia and the University of Western Australia. The aim is to identify progeny of both the apple and plum breeding programs that have elite levels of flavonoids and to demonstrate health benefits of a high-flavonoid apple. This could lead to significant benefits to Australian horticulture and to population health.Read moreRead less
Regulation of principal components of the antioxidant system in table grapes. An expanded ?health-claims? system will likely be enacted by Food Standards Australia New Zealand within two years. Horticultural industries are attracted to the promotional ?point of difference? this offers. Many health-promoting compounds are antioxidants, including polyphenols that are abundant in fruit such as grape and citrus.

An expanded ?health-claims? system will likely be enacted by Food Standards Australia New Zealand within two years. Horticultural industries are attracted to the promotional ?point of difference? this offers. Many health-promoting compounds are antioxidants, including polyphenols that are abundant in fruit such as grape and citrus. Antioxidants are also involved in the plant's defences against abiotic and biotic stress. Here, the WA Table Grape industry has committed funds for an APAI to study regulation of antioxidants in relation to nutritional and postharvest qualities. Effects of preconditioning with mild oxidative stresses will be assayed, postharvest, using molecular and biochemical techniques.Read moreRead less
New Approaches to the Control of Post-Weaning Diarrhoea in Piglets. In Australia, post?weaning diarrhoea (PWD) in piglets is a major constraint to efficient and profitable production. Increasing levels of resistance to dietary antibiotics by gut pathogens such as Escherichia coli, the bacterium implicated in PWD, is a major reason for this problem. This research will identify nutritional means of controlling PWD and increasing production after weaning. This will be achieved by strategic nutritio ....New Approaches to the Control of Post-Weaning Diarrhoea in Piglets. In Australia, post?weaning diarrhoea (PWD) in piglets is a major constraint to efficient and profitable production. Increasing levels of resistance to dietary antibiotics by gut pathogens such as Escherichia coli, the bacterium implicated in PWD, is a major reason for this problem. This research will identify nutritional means of controlling PWD and increasing production after weaning. This will be achieved by strategic nutritional interventions in the pre-weaning and (or) post-weaning periods targeted at reducing bacterial pathogens in the gut. A reduction in PWD will increase the overall efficiency of pig production in Australia and reduce antibiotic use.Read moreRead less
Role of organic matter and soil biota in optimising crop nutrition in sustainable farming systems. Australian grain producers face increasing competition on the world market from countries with cheap production costs (China, Argentina, Brazil). This project will develop biological farming systems based on improving soil health and enhancing soil microflora and nutrient cycling. Western Australia and other states are currently defining certification guidelines for sustainable farming systems (inc ....Role of organic matter and soil biota in optimising crop nutrition in sustainable farming systems. Australian grain producers face increasing competition on the world market from countries with cheap production costs (China, Argentina, Brazil). This project will develop biological farming systems based on improving soil health and enhancing soil microflora and nutrient cycling. Western Australia and other states are currently defining certification guidelines for sustainable farming systems (including biological ones). Selling grain produced in certified biological farming system will attract market premium, therefore enhancing the position of Australian farmers. This project will produce fertiliser recommendation systems incorporating organic fertilisers, thus decreasing costs of production and maintaining clean and healthy environment.Read moreRead less
Modelling spatial and temporal dynamics of rhizosphere exudation. Existing crop root systems are poorly suited to Australian soils with low nutrient availability. Using a simulation model to develop computer-aided design of 3-D root structure and function, tailored to particular environments, this project will enhance breeding for increased nutrient-use efficiency.
Role of nitrogen and sulphur nutrition in determining quantity and quality of oil in canola seed. Canola is the second most important crop in Australia, with exports worth $1 billion a year. However, competitiveness of Australian canola on the world markets is hampered by low and inconsistent oil content. Nitrogen fertilisation increases seed yield and seed protein content, but decreases oil content. This project will elucidate regulation by nitrogen and sulphur (the other important nutrient in ....Role of nitrogen and sulphur nutrition in determining quantity and quality of oil in canola seed. Canola is the second most important crop in Australia, with exports worth $1 billion a year. However, competitiveness of Australian canola on the world markets is hampered by low and inconsistent oil content. Nitrogen fertilisation increases seed yield and seed protein content, but decreases oil content. This project will elucidate regulation by nitrogen and sulphur (the other important nutrient in canola growth) of protein and oil biosynthesis in developing canola grain. The knowledge generated in this project will allow optimisation of canola agronomy and more effective breeding for increased nitrogen- and sulphur-use efficiency, seed yields and oil content in canola, thus enhancing the competitiveness of Australian canola on the world markets.Read moreRead less

Uncle Bens of Australia has a significant share of this market. Development of dog foods based on vegetable proteins offers new market opportunities domestically, and overseas. Numerous vegetable proteins are available, however anti-nutritional factors that reduce digestibility and deteriorate faecal quality might limit their use. To optimise their dietary inclusion, physiological effects in the canine gut must be understood to avoid any negative effects. These may be overcome by enzymes and (or) processing, and would allow cost effective products to be formulated that deliver optimum health and nutrition to consumers.
