Summary
Increasing the daily intake of water is well known to reduce the risk of developing kidney stones but there is growing evidence that it may also benefit other kidney diseases, particularly autosomal dominant polycystic kidney disease (ADPKD). This study will determine if adequate hydration can slow the progression of ADPKD, and could provide a relatively simple and cheap treatment for preventing the onset of kidney failure due to this disease.

Summary
Chronic kidney disease (CKD) is a major public health problem affecting over 1.5 million Australians and is associated with increased risk of death, heart disease and progression to end-stage kidney disease (ESKD). Current treatments to slow progression to ESKD are limited. The CKD-FIX trial aims to find out whether treatment with allopurinol, a commonly used drug for gout prevention, safely and effectively slows CKD progression. This could lead to significant health and economic benefits.

Summary
Respiratory disease is an important child health issue with long term implications into adulthood. The evaluation of small airways involvement in disease processes, using an accurate sensitive measures of function, such as forced oscillation technique and multiple breath washout, potentially facilitates not only early detection of disease, but instigation of earlier treatment, better assessment of response to treatment, and ultimately better outcome.
Metabolically Reprogramming The Stroma To Starve Pancreatic Tumours

Summary
Pancreatic cancer claims five Australian lives every day. Despite aggressive treatment regimes, there has been no improvement in patient survival in the last decade. Evidence suggests that targeting cancer cells alone is not enough. Pancreatic tumours are surrounded by an extensive scar tissue reaction (stroma). This intense stromal reaction inhibits drug delivery and increases tumour growth. Thus, decreasing the stroma is a potential therapeutic strategy and is the focus of this proposal.
Understanding The Origins Of Diabetes And Kidney Disease In Aboriginal Children And Their Mothers

Summary
Kidney disease is 10 times higher for Indigenous compared to non-Indigenous Australians. Treatment involves many losses (time, functioning, role and disconnection from family and country). This study is the first to explore effectiveness of a culturally adapted electronic mental health intervention – The AIMhi Stay Strong App for improving wellbeing, quality of life and treatment adherence for Indigenous patients on haemodialysis. Cost effectiveness of the intervention is also assessed.
Vascular And Neurogenic Determinants Of Hypertension In Chronic Kidney Disease

Summary
You are as old as your arteries, and people with kidney disease have arteries that age fast. They also have overactive sympathetic nerves, and it is not clear if the blood vessels or nerves are responsible for the high blood pressure that puts strain on the heart and other organs of these patients. We will use an animal model to determine if therapy for hypertension reduces the stiffness of blood vessels or elevated nerve activity. Our results will enable better treatments for kidney failure.
Stress During Pregnancy And The Developmental Origins Of Renal Disease In Aboriginal Australians

Funding Amount
$866,044.00
Summary
There is an epidemic of renal failure in Aboriginal people who also have high rates of premature birth of small babies. This project aims to understand the causes of kidney failure in Aboriginal people through testing if stress during pregnancy leads to the birth of preterm, small babies with small poorly formed kidneys that lead to kidney failure in later life. The effect of stressors impacting on pregnant women including infections, exposure to smoking and social stressors will be examined.

Summary
The thin layer of fluid covering the surface of the air passages acts to protect the airway surface from drying. This fluid also allows the hair-like projections, or cilia, on the top of the airway cells to beat more effectively. The volume and composition of this fluid is determined by the movement of salt and water across the mucous membranes of the air passages. The importance of this fluid is shown by the problems that occur in Cystic Fibrosis (CF), the most common lethal inherited disease a ....The thin layer of fluid covering the surface of the air passages acts to protect the airway surface from drying. This fluid also allows the hair-like projections, or cilia, on the top of the airway cells to beat more effectively. The volume and composition of this fluid is determined by the movement of salt and water across the mucous membranes of the air passages. The importance of this fluid is shown by the problems that occur in Cystic Fibrosis (CF), the most common lethal inherited disease affecting Australians. In CF, altered salt transport causes drying of the airway surface which impairs the working of the cilia. This leads to retention of mucous in the airway with repeated bacterial infections damaging the lungs. Simple tests have been designed to directly measure the movement of salt across the surface of the nasal passage using a fine soft rubber tube. Movement of mucous in the nose is measured using other simple techniques that are currently used diagnostically. Together, these tests in the nose provide vital information about how the surface of normal human airway moves salt, water and mucous. Any differences found in CF patients will then give us a good idea of the problems found in the CF lung. We will study the interactions between calcium, sodium and chloride in the fluid lining the airways, measuring changes in salt and mucous movement. A range of testing procedures will be used in human volunteers, anaesthetised mice and isolated tissues from sheep. We have already demonstrated important links between the fluid lining the airways and salt movement, and we expect that this may lead to the development of new treatments for Cystic Fibrosis. This therapy will focus on treating the lung problems of CF patients, the major cause of disability. We anticipate that this preventative therapy may offer real benefits in the fight to cure CF.Read moreRead less

Summary
One of the most important evolutionary changes that has occurred is the development of intracellular compartments. All eukaryotic cells possess numerous membrane-encased structures which provide the basis for intracellular specialisation. For example, in order to degrade unwanted components cells have developed degradative enzymes. It is vital for the cell that these enzymes are sequestered away from other cellular components to avoid destruction of valuable molecules.

All eukaryotic cells possess numerous membrane-encased structures which provide the basis for intracellular specialisation. For example, in order to degrade unwanted components cells have developed degradative enzymes. It is vital for the cell that these enzymes are sequestered away from other cellular components to avoid destruction of valuable molecules. In addition, the cell has developed a complex assembly line of modifications that are added to proteins in a specific order as they travel to their final destination within the cell. This necessitates the accurate passage of molecules between compartments, a process known as vesicle transport. To orchestrate the complex network of vesicular transport steps between all of the various intracellular compartments it is necessary to employ complex machinery to guide and check that these steps occur with high fidelity. The goal of our research proposal is to define the function of one of the molecules involved in this control process, the so-called Sec1p proteins. The strength of our proposal lies in the diversity of our approach. We intend to explore the molecular advantages of a relatively simple eukaryotic organism, a yeast cell, and apply the findings obtained from this cell to a more complex but highly related vesicular transport process; that of the insulin-regulated movement of a glucose transporter in mammalian fat and muscle cells. While we intend to apply our findings to the treatment of patients with diabetes, it is our ultimate goal to be able to learn more about this fundamental cell biological process so that we can apply our knowledge to understanding many different disease states.Read moreRead less
