It has become increasingly evident that damage to the genetic material in cells (DNA) is a fundamental initiating cause of cancer and accelerated ageing. Furthermore it has been shown recently that moderate deficiencies of certain vitamins and minerals can cause damage to DNA at a level that is observed for carcinogenic doses of radiation and toxic chemicals. In addition studies have shown that supplementation with certain vitamins resulted in a reduction of damage to DNA.

Furthermore it has been shown recently that moderate deficiencies of certain vitamins and minerals can cause damage to DNA at a level that is observed for carcinogenic doses of radiation and toxic chemicals. In addition studies have shown that supplementation with certain vitamins resulted in a reduction of damage to DNA. The aims of this research is to determine whether daily intake of a pill containing certain vitamins and minerals causes a reduction in DNA damage in blood cells. The expected ultimate outcome is a cancer prevention strategy based on reducing the risk of damage to DNA.Read moreRead less
Genotypes And Phenotypes Of Human Primary Non-congenital Antibody Deficiency

Summary
Antibodies represent a key component of the immune system, and a particularly important in defence against bacterial and viral infections. In some individuals, antibody production fails, rendering them more susceptible to infection. In most cases, the mechanism of antibody failure is unknown. This project seeks to determine the genetic and cellular mechanisms of antibody failure. This could improve diagnosis for immune deficiency, and improve our overall understanding of the immune system.
Secretion is an essential step in memory and learning, control of metabolism and reproduction and the functioning of most organs. Secretory dysfunction also underlies many diseases including type 2 diabetes. We plan experiments to test for a new model of control of insulin secretion.
Role For Zinc And ZIP2 In The Action Of Nitric Oxide And In Vascular Protection Against Cigarette Smoke And Cardiovascular Disease

Summary
The NO/cGMP signalling pathway, which is central to cardiovascular physiology and protection against disease, is only fully effective when there are adequate levels of zinc in the vascular endothelium. This is especially important where zinc stores are depleted (elderly, smokers, diabetics and kidney disease). There is an urgent clinical need to implement strategies to monitor vascular Zn status. This application will explore the underlying science and translate these to the clinic.
Defining The Role Of Zinc At The Host-pneumococcal Interface

Funding Amount

Summary
Streptococcus pneumoniae is the world’s foremost bacterial pathogen. In Australia, bacterial infections are responsible for more than 9000 deaths every year, and the economic burden associated with treating diseases arising from pneumococcal infections is more than $1 billion annually. This proposal aims to define the role of the transition metal zinc in innate immune resistance to bacterial infection. This knowledge will reveal new targets for next generation antimicrobial therapeutics.
Defining The Impact Of Universal Iron Interventions In Young Children: A Randomized Controlled Trial In Rural Bangladesh

Funding Amount
$2,794,373.00
Summary
Although nearly half of the world's young children are anaemic, evidence regarding the best approaches to correct this problem are limited. New data even suggests that the conventional approaches (iron supplements, multiple micronutrient powders) may even be harmful. We will perform the definitive trial which will confirm the existence and magnitude of any benefit (and harm) from these interventions in young Bangladeshi children. This trial will inform global policy on anaemia control.
