Summary
The ADVANCE (Action in Diabetes and Vascular Disease) study demonstrasted that intensive control of blood glucose only reduced kidney disease but that control of blood pressure reduced both cardiovascular and kidney disease. This 10-year post-trial follow up study will determine whether intensive control of blood glucose exerts cardiovascular benefits that emerge in the long term in patients with type 2 diabetes.
Type 2 Diabetic Renal Complications And Microvascular Injury: Novel Predictors Of Onset And Progression, Mechanisms Of Association With Cardiovascular Disease And The Benefits Of Fenofibrate.

Summary
We will investigate the mechanisms of diabetic complications related to kidney and blood vessel disease, focusing on identifying people at greater risk and ways to improve or prevent these complications. In addition, we will look at how diabetic kidney disease affects non-kidney related problems like heart disease and examine the benefit of fenofibrate on both. This greater understanding will aid further drug development in kidney and cardiovascular diseases.
This study aims to identify naturally occurring genetic variations between men which modify the impact of testosterone, the major male hormone, on men's health and medical care. This study will examine new factors which determine how much any particular man may gain benefit from testosterone exposure such as in muscle and bone development as well as suffer detrimental effects on cardiovascular and prostate diseases. This may clarify some new aspects of how men's health is determined as well as d ....This study aims to identify naturally occurring genetic variations between men which modify the impact of testosterone, the major male hormone, on men's health and medical care. This study will examine new factors which determine how much any particular man may gain benefit from testosterone exposure such as in muscle and bone development as well as suffer detrimental effects on cardiovascular and prostate diseases. This may clarify some new aspects of how men's health is determined as well as developing new, customized medical treatments for men.Read moreRead less

Diabetes is increasing worldwide and in Australia. The majority of patients with diabetes eventually will develop kidney disease and will die of blood vessel complications such as heart attacks and stroke. Oxidative stress (the generation of free oxygen radicals that react quickly with other proteins in the body causing tissue damage) has been suggested to play an important role in kidney and blood vessel disease observed in diabetic patients.

The majority of patients with diabetes eventually will develop kidney disease and will die of blood vessel complications such as heart attacks and stroke. Oxidative stress (the generation of free oxygen radicals that react quickly with other proteins in the body causing tissue damage) has been suggested to play an important role in kidney and blood vessel disease observed in diabetic patients. This proposal will try to identify and measure specific proteins in the kidney and vessels that are involved in the production of oxidative stress. We aim to define which one of these proteins is the most important. We will assess in detail how these proteins work and which other factors are activated leading to tissue damage. The ultimate goal of these studies is to find new treatment options to decrease the production of harmful molecules in the kidney and blood vessel wall thereby reducing kidney failure, heart attacks, stroke and gangrene in diabetes. In our studies, we will use medications already used in patients to treat high blood pressure in diabetes. In preliminary studies we have shown that these drugs also reduce oxidative stress. Furthermore, we will use novel, more specific treatments that the harmful ptoteins. Through a collaboration with Professor Harald Schmidt and his group from Germany who have recently moved to Monash University in Melbourne we will have access to mice in which specific genes for harmful proteins have been knocked out. These mice when made diabetic will most likely develop less or no kidney and blood vessel damage. Our studies will help to identify the most important oxidative stress producing protein associated with kidney and vessel disease. This knowledge will lead to more effective and more potent treatments for patients with diabetes to prevent, stop or even improve kidney and blood vessel disease thereby reducing disability and death in this high risk group of patients.Read moreRead less
Brown fat protects animals against obesity and diabetes. Humans with abundant brown fat are metabolically healthy. Identification of medication that boosts brown fat function may lead to novel treatment of metabolic disorders. This proposal will examine the role of such a medication, which is modeled on a factor (called FGF21) released from brown fat. The project will also search for other factors released by human brown fat, which may become future targets of obesity treatment.
The effects of therapeutic glucocorticoid doses on carbohydrate and energy metabolism and cardiovascular risk have not been fully clarified. This PhD thesis will be based around two studies aiming to: 1.) Define mechanisms underlying the adverse effects of low dose prednisolone in patients with inflammatory rheumatologic disease and 2.) Improve treatment of prednisolone-induced hyperglycaemia in hospitalized patients.

Summary
Diabetes can cause eye, kidney, heart and nerve damage. The applicant will lead human studies of treatments to prevent complications, improve blood glucose and co-ordinate care. Early outcome prediction would enable better treatment of high-risk people, monitoring of therapy, and development of new treatments. Dr Jenkins also has a network with data and samples from over 35,000 people with diabetes, preliminary data, and a team to measure markers and test new treatments in the lab.

Summary
People with diabetes most commonly die from stroke or heart attack and we need to determine what makes them more prone to these problems. The recently discovered UII system is increased in people with diabetes and has been found in diseased parts of blood vessels. Thus, the aim of this project is to characterise the UII system in the setting of diabetes using 2 unique genetically altered mice and a blocker a to study the effects of high cholesterol, diabetes and a deletion of UII.
Dietary Fats As Drivers Of Obesity-related Inflammation

Summary
Obesity leads to diabetes and heart disease but not all body fat seems to be bad. Increased fat around the waist (especially the visceral fat around the intestine and internal organs) is particularly bad. Visceral fat secretes a lot of inflammatory molecules. This research aims to understand how visceral fat becomes inflamed and how we might use diet and other methods to reduce both the amount of visceral fat and its level of inflammation; thus reducing both obesity and its health consequences.
