Summary
Cardiovascular disease is the major source of death in developed countries. In Australia it accounts for more deaths than cancer and is associated with considerable economic cost. The use of antioxidant vitamin supplements for reduction of heart disease risk is now discouraged because several large studies with vitamin E (containing one form of vitamin E called alpha-tocopherol) have shown no benefit. However, there remains a major discrepancy between intervention studies using pure alpha-tocoph ....Cardiovascular disease is the major source of death in developed countries. In Australia it accounts for more deaths than cancer and is associated with considerable economic cost. The use of antioxidant vitamin supplements for reduction of heart disease risk is now discouraged because several large studies with vitamin E (containing one form of vitamin E called alpha-tocopherol) have shown no benefit. However, there remains a major discrepancy between intervention studies using pure alpha-tocopherol and population studies showing a benefit of diet derived antioxidants. We believe that this project will help clarify this discrepancy and provide data which may provide evidence for functional foods enriched with another form of vitamin E called gamma-tocopherol. Gamma-tocopherol is common in some foods and it may have different properties compared to alpha-tocopherol. We have already established that supplementation for six weeks with gamma-tocopherol leads to a marked increase in blood and tissue levels of gamma-tocopherol. Dietary gamma-tocopherol has potential antiinflammatory activity. This project will study how gamma-tocopherol may work as an antiinflammatory agent which could help to protect against heart disease. The project will clarify the potential role of dietary gamma-tocopherol in cardiovascular disease and strengthen the recommendation for mixed dietary 'antioxidants' in place of pure supplements such as alpha-tocopherol.Read moreRead less
The Microenvironmental Drivers Of T Cell Regulation In Metastatic Breast Cancer

Summary
COX2 inhibitors are drugs commonly used by cancer patients to relieve pain and inflammation. Using human breast cancer samples and mouse models of breast cancer, we show that pathways targeted by these drugs provide an immunological brake that prevents T cells being activated as strongly as they could be, and which has not been studied. This project is expected to yield important anti-cancer targets that could be used to develop a new class of cancer drugs.
A Multicentre Randomised Clinical Trial Of Physical Activity For The Treatment Of Patients With Alzheimers Disease

Summary
The number of older adults living with Alzheimer's disease (AD) will increase from 26.6 million to 106.2 million by 2050. In the absence of curative treatment options it is important to focus on non-pharmacological interventions such as physical activity. We propose to investigate whether a home-based physical activity program of 24 weeks for patients with AD can successfully decrease the rate of cognitive and functional declince and improve quality of life and psychological well-being.
Studies Of Metabolites Of Synthetic Flavonols For The Treatment Of Cardiovascular Disease

Summary
Cardiovascular disease, including heart attack and stroke, is the leading killer of Australians. A promising new drug, NP202, can reduce the amount of tissue damaged from a heart attack; however, its mechanism of action remains obscure. NP202 is metabolized to a range of compounds, one of which is partly responsible for its beneficial effects. In this project we will identify other metabolites of NP202 and characterize their biological activity to gain insight into its mechanism of action.
Physical Activity Coaching For Adults With Physical Disabilities: A Pragmatic Randomised Controlled Trial.

Funding Amount
$1,371,185.00
Summary
People with impaired mobility can achieve substantial benefits from appropriate physical activities but face many barriers to being active so require targeted interventions and health professional support. This trial (n=600) will test the effectiveness and cost-effectiveness of an enhanced physical activity coaching intervention (home-visit from a physiotherapist, phone coaching, technology) with phone coaching alone and with no intervention.
