Bisphosphonate Treatment Of Childhood Femoral Head Avascular Necrosis Due To Perthes Disease

Summary
Perthes disease (PD) occurs following loss of blood supply to the hip (femoral head). It is a severe childhood disorder with over 250 new cases per year in Australia. PD results in flattening of the normally round femoral head and painful arthritis. The hip becomes flat because the bone is eaten by cells called osteoclasts. We will test if a medicine aimed at stopping these osteoclasts can prevent hip flattening. This should decrease the risk of arthritis and the need for hip replacement.
Central Aortic Blood Pressure In Children: Establishing A Gold Standard Non-invasive Assessment Of Cardiovascular Risk

Funding Amount
$694,342.00
Summary
The best way of assessing early risk of cardiovascular disease involves measuring blood pressure near the heart (central pressure), but existing devices used in adults for this purpose are inaccurate in children. We will develop a children-specific method and apply it to study early cardiovascular risk in a comprehensive health study of 2000 children Australia-wide. We will also investigate why children with congenital heart disease frequently develop ‘older-adult’ heart disease at a young age.
NDI1 Therapy For NADH-Ubiquinone Oxidoreductase Deficiency

Funding Amount
$575,762.00
Summary
This study will test a new protein therapy that can act as a surrogate for a deficient or defective enzyme called Mitochondrial Complex 1. The deficiency occurs in newborns with defective genes for the proteins that form the enzyme. The defect causes metabolic malfunction in most organs, with patients needing specialist hospital and parental care, but there is no cure yet. We have successfully tested this in the lab but will now test this in our new animal model of the disease.
Evaluation Of Antibody Levels And Function In Otitis-prone And Healthy Australian Children

Funding Amount

Summary
Middle ear infections are the most common reason for a child to see a doctor, receive antibiotics and undergo surgery. We have collected blood and saliva samples from children with and without ear infections to compare their antibody responses to bacteria that cause middle ear infections. We will also investigate whether there is a good host response at the site of inflammation, i.e. the middle ear.
Childhood Lymphatic Malformations: The Mechanism Of Rapamycin In Controlling Growth

Funding Amount

Summary
Lymphatic malformations (also known as cystic hygromas or lymphangiomas) cause deformity and pain which can last lifelong. Current treatments help but do not fix all the symptoms. Rapamycin, a drug used for many years in children and adults with kidney transplants, may be useful for treating children with lymphatic malformations. We aim to understand how the drug works on the cells of lymphatic malformations in culture and in an animal model, to develop new and more effective treatments.
Airway Epithelial Barrier Function, Asthma And Aero-allergen Sensitization.

Summary
There is a strong association between allergy and asthma. This association been almost universally assumed to be causative. However, recent evidence suggests an alternative explanation ie., that the abnormal epithelium in asthma allows or facilitates sensitization to airborne allergens. This project will test this alternative hypothesis using human lung tissue and an animal model.
The Clinical Impact Of Event-based Motion Correction In Paediatric PET-CT Brain Imaging

Funding Amount
$276,104.00
Summary
Movement of the head during PET-CT brain imaging can prevent accurate diagnosis by blurring and distorting the image. The problem is perhaps most acute in paediatric patients, many of whom must be anaesthetized or sedated to avoid motion. This work will establish whether a recently developed motion correction method can improve the clinical utility of PET-CT brain images in young patients, and reduce the need for sedation and anaesthesia during the PET scan.
Systems Biology Of Asthma Development In Early Childhood
Funder
National Health and Medical Research Council
Funding Amount
$763,800.00
Summary
Recent studies have established that both human genetic susceptibility and viral infections during early childhood are important drivers of asthma development. It has also been noted that asthmatics’ airways are colonized with different bacteria to non-asthmatics. In this project we will examine how genetic susceptibility and interactions between bacteria and viruses in children's airways promote the development of allergy and asthma.
This study will follow up a birth cohort for 25 years with the aim of looking at critical periods for bone development including the role of in utero exposures, early infancy, age 8 and age 16.
Human RIPC-derived Regulatory Molecules For Cardioprotection Against Ischemic And Cardiopulmonary Bypass Injury

Funding Amount
$642,083.00
Summary
Our previous work indicates that evoked human blood borne factors confer protection against injury, due to loss of blood flow in heart muscle, when a brief stress is remotely applied to a limb (remote ischemic preconditioning). We have identified these proteins that appear to activate genetic and metabolic regulation of adaptive cell survival processes. We will now test their individual and combined capacity, efficiency and mechanisms of protection in the heart using cell and clinical models.
