Summary
We will determine how low oxygen levels in the kidney lead to kidney disease. We can now measure the levels of oxygen in kidney tissue in rats 24 hours a day, 7 days a week, in a completely non-invasive way. We will study two common kinds of kidney disease. One, acute kidney injury, can result from administration of contrast agents used in x-ray diagnostic procedures. The other, chronic kidney disease, is common in patients with diabetes or high blood pressure.
Towards Prevention Of Acute Kidney Injury After Cardiac Surgery

Summary
Open heart surgery saves thousands of lives each year in Australia, but often injures the kidney. Kidney oxygen deficiency is a major cause of kidney injury. We propose a new way to manage kidney oxygen levels during heart surgery, by measuring the level of oxygen in the urine in the bladder. We will determine whether low levels of oxygen in the urine during surgery predict later development of acute kidney injury, and whether patient management can be changed to optimize kidney oxygen levels.
This project examines the types of computations used by brain cells to combine two types of sensory information, in a way that allow us to reach better decisions in everyday life. To address this general problem, we will perform experiments that explore the combination of signals from vision and hearing. The ability to combine sensory information is vital to our mental health, and this process is compromised in a range of psychological, psychiatric and neurological disorders.
Does Periodic Fasting Improve Insulin Sensitivity And Metabolic Health In Humans?

Summary
A large body of evidence for the health benefits and life-extending properties of dietary restriction exists. Recent findings suggest that periods of fasting can have beneficial effects, even without an overall reduction in caloric intake. This proposal will compare periodic fasting with and without weight loss, versus daily caloric restriction on metabolic health outcomes in humans and examine mechanisms that may contribute to this effects.
Influence Of In Utero Environment On Diaphragm Structure And Function

Summary
The diaphragm is the major muscle involved in breathing. Normal function of the diaphragm is essential to survival. Preterm babies may be exposed to infection and other agents that interfere with diaphragm development and make breathing efforts weaker after birth, potentially leading to respiratory failure. This study will study diaphragms of preterm lambs to determine how fetal exposure to infection and steroids affect fetal diaphragm development, and if adverse effects are prevented by fetal t ....The diaphragm is the major muscle involved in breathing.
