Summary
The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain ....The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain cells perform specialised functions. In test-tube experiments, IGFBP-3 and IGFBP-5 interact directly with the receptors that regulate the effects of these hormones. If the same thing happens inside the cell, IGFBP-3 and IGFBP-5 could change the way these receptors respond to signals from outside the cell. We will investigate what effect these IGFBPs have in living cells and in whole animals and how this may relate to human disease. If we are able to understand how IGFBP-3 and IGFBP-5 affect the way cells respond to vitamin A and D, then we may be able to develop new ways to treat certain human diseases.Read moreRead less
Aspirin For The Prevention Of Cognitive Decline In The Elderly: A Neuro-Vascular Imaging Study (ENVIS-ion) From ASPREE

Funding Amount
$1,341,232.00
Summary
The ENVIS-ion trial will examine whether Aspirin is effective in delaying the onset of worsening of thinking and memory abilities in healthy older adults. Magnetic resonance imaging (MRI) of brain structure will detect markers of early worsening of thinking and memory abilities. Blood vessels in the back of the eye (retina) share many features with vessels in the brain. We will compare whether aspirin lessens changes over time of features shown with brain MRI and retinal photography.
Ventilation Heterogeneity And Airway Remodelling In Asthma

Summary
Asthma is a common and important as a cause of significant symptoms and even death. Associated with asthma is narrowing and stiffening of the arways which causes uneven ventilation of the lungs and reduced lung function. We have developed a new technique of imaging the lungs, as well as new lung function tests which measure uneven ventilation and stiffening of airways. This will help us design better medications, and help predict those who are at risk or severe asthma and death.
