Do ‘classical’ Or ‘oxidative’ UVR-induced DNA Adducts Drive Melanoma Induction After Ultraviolet Radiation

Summary
There is debate about the mechanisms by which sun exposure influences melanoma development. This leads to difficulties in formulating adequate sunscreens and guidelines for safe levels of exposure. We will elucidate the critical UV-induced DNA adducts that are necessary for MM development. This will introduce experimental evidence into the debate about sun exposure and melanoma. The use of post sunburn creams containing enzymes which rapidly remove the dangerous DNA adducts will be indicated.
Brm And Brg-1 Protect From Ultraviolet Radiation-induced Skin And Ocular Damage

Summary
Ultraviolet radiation within sunlight is the most important environmental hazard to which Australians are exposed. It causes cancers of the skin and eye, in addition to other forms of skin and eye damage. However sunlight also has health benefits such as vitamin D production. To protect our health from the sun we need to understand how it causes damage and the meachanisms involved. We have discovered a new pathway that we plan to study, called Brm and Brg-1, that provides protection from UV.
Improving Skin Cancer Prevention: Motivating Preventive Behaviours Using Knowledge Of Personalised Genomic Risk Of Melanoma

Summary
The aim of our study is to evaluate whether we can improve the Australian public’s skin cancer prevention behaviours, particularly reducing exposure to ultraviolet (UV) radiation, by giving personalised information about melanoma genetic risk. We will also explore the psycho-social, ethical, and economic implications of receiving this information. The results of our study are likely to influence the future of skin cancer prevention in Australia.
The Role Of Vitamin D In Determining Risk Of Developing Juvenile Idiopathic Arthritis

Summary
Juvenile Idiopathic arthritis (JIA) is an autoimmune disease that occurs in up to 1/250 Australian children. Growing evidence suggests that low vitamin D increases risk of autoimmune disease, yet no-one has looked at its effect on JIA. We will compare vitamin D in blood, and also exposure to sun through life, between children with and without JIA. We will also look to see if vitamin D interacts with autoimmune disease risk genes. The outcomes of this study will help to inform policy on the impor ....Juvenile Idiopathic arthritis (JIA) is an autoimmune disease that occurs in up to 1/250 Australian children.

There is a need for a greater understanding of the complex relationship between sun exposure and the production of Vitamin D. This study will expand on the recently-completed AusD study to examine how personal, behavioural, and environmental factors impact on intra-individual seasonality in Vitamin D production. The study findings will guide the development of specific, evidence-based public health recommendation that balance the risks and benefits of sun exposure.
T-follicular Helper Cell Subsets That Induce Protective Anti-Plasmodium Falciparum Antibodies

Summary
Malaria claims at least half a million lives each year, the majority of them in children under the age of 5 years. In order to development effective vaccines malaria it is critically important that we increase our understanding of the key mechanisms governing the induction of protective immune responses in naturally exposed populations. This project will examine the role of one important cell subset - T-follicular helper cells - in the development of immunity against malaria.
Multistage Vaccines For The Prevention Of Tuberculosis

Summary
Almost two million people die from tuberculosis (TB) each year. The current vaccine, BCG, is ineffective at controlling TB and the type of immune response needed to protect against the disease is poorly understood. We have discovered new antigens of the TB bacterium, and we will combine them with novel delivery strategies to develop new TB vaccines. We will also determine the type of immune response needed to protect against TB, which will aid progression of vaccines into clinical trials.
Delayed Loss Of Acoustic Hearing After Cochlear Implantation: Mechanisms And Clinical Identification With New Cochlear Implant Technology

Summary
Natural hearing can be combined with a cochlear implant to improve sound quality and speech understanding. However, natural hearing frequently deteriorates weeks to months after cochlear implantation. This seems to occur when cochlear fluid buildup (hydrops) or fibrosis within the inner ear disrupts cochlear mechanics. We plan to monitor these processes in patients by recording directly from the cochlear implant, and conduct laboratory experiments to find therapies to alleviate their effects.
Nanoengineered Drug Delivery To The Inner Ear To Prevent Progressive Hearing Loss

Funding Amount

Summary
Hearing loss is a common sensory deficit and can get progressively worse over time, eventually requiring a cochlear implant. In this project we will examine the effectiveness of a new technique that uses nanoengineered particles to provide long term and controlled delivery of drugs in order to prevent progressive hearing loss and protect residual hearing following cochlear implantation. We will develop the next generation of nanotechnology to enhance drug delivery in pathological ears.
FluMum: A Prospective Cohort Study Of Mother-infant Pairs Assessing The Effectiveness Of Maternal Influenza Vaccination In Prevention Of Influenza In Early Infancy

Summary
Influenza is a serious illness for young babies. Currently there are no vaccines that can be given to babies under 6 months of age to protect them from infection. This study aims to determine whether influenza vaccine given in pregnancy can prevent infection in babies up to 6 months of age.
