Modulating the molecular and cellular physiology of ageing skeletal muscle. Understanding the underlying mechanisms of how ageing affects muscle is of increasing importance to the community as the number of older persons in the population continues to escalate and the age of retirement increases. Old muscles are slower and weaker than young muscles, and are more easily injured. This proposal is focussed on developing safe therapies to prevent or reverse these age-related effects.

Understanding the underlying mechanisms of how ageing affects muscle is of increasing importance to the community as the number of older persons in the population continues to escalate and the age of retirement increases. Old muscles are slower and weaker than young muscles, and are more easily injured. This proposal is focussed on developing safe therapies to prevent or reverse these age-related effects. Making old muscles young again, is a research strategy that will promote healthy ageing and enable older Australians to enjoy a better quality of life.Read moreRead less
Estrogen signalling in gonadotropes. Estrogen action is a normal prerequisite for cyclic function of reproduction in the female, but little is known about how this important hormone acts in the relevant cells of the pituitary gland (gonadotropes). In order to gain information on normal function, we will conduct studies on gonadotropes treated with estrogen in a range of paradigms. The information will be valuable in understanding normal reproduction, but will also form the basis of further studi ....Estrogen signalling in gonadotropes. Estrogen action is a normal prerequisite for cyclic function of reproduction in the female, but little is known about how this important hormone acts in the relevant cells of the pituitary gland (gonadotropes). In order to gain information on normal function, we will conduct studies on gonadotropes treated with estrogen in a range of paradigms. The information will be valuable in understanding normal reproduction, but will also form the basis of further studies to investigate the effects of drugs that affect estrogen action and environmental estrogens.

Summary
Hyperpolarised gas functional lung and molecular imaging. This project will produce a polariser to generate magnetised gas for research with magnetic resonance imaging (MRI). This allows imaging of normal and abnormal lung ventilation and circulation in animal and humans. The use of these hyperpolarised gases can also be used to tag specific molecules and increase understanding of lung metabolism.
Role of suppressor of cytokine signalling proteins (SOCS3) in defective muscle repair and ageing. Old muscles are slower and weaker than young muscles, they are injured more easily and they repair less successfully. This proposal investigates the role of SOCS3-signalling in muscle repair, ultimately to improve healing and to promote healthy ageing that will enable older Australians to enjoy a better quality of life.
Dietary sugarcane-derived polyphenols reduce obesity. The Australian Sugar Industry is a billion dollar industry with refined sugar being calorie-rich but nutrition poor. Consumption of refined sugar is a main contributor to the increasing problem of obesity and metabolic syndrome, costing the Australian health system billions of dollars annually. The principal outcomes of this project will be to show that the polyphenols contained in the waste products from sugar refining can be used to reduce ....Dietary sugarcane-derived polyphenols reduce obesity. The Australian Sugar Industry is a billion dollar industry with refined sugar being calorie-rich but nutrition poor. Consumption of refined sugar is a main contributor to the increasing problem of obesity and metabolic syndrome, costing the Australian health system billions of dollars annually. The principal outcomes of this project will be to show that the polyphenols contained in the waste products from sugar refining can be used to reduce body fat and insulin resistance. These outcomes have enormous implications for human health and disease, and for the sugar industry, thus providing a competitive edge in the world sugar market.Read moreRead less
Use of an animal model to understand mechanisms underlying reductions in body weight associated with use of the laparoscopic adjustable gastric band. At least one in ten Australians is classified as morbidly obese and as such are eligible for bariatric surgery. Those undergoing the surgery will achieve an average excess weight loss of up to 60 per cent, they will have reduced or eliminated diabetes and will appreciably improve their prospects of survival. These experiments aimed at understandin ....Use of an animal model to understand mechanisms underlying reductions in body weight associated with use of the laparoscopic adjustable gastric band. At least one in ten Australians is classified as morbidly obese and as such are eligible for bariatric surgery. Those undergoing the surgery will achieve an average excess weight loss of up to 60 per cent, they will have reduced or eliminated diabetes and will appreciably improve their prospects of survival. These experiments aimed at understanding the mechanisms underpinning this success have the potential to further improve surgical approaches and outcomes and provide insights that will better enable weight loss therapies for all overweight and obese Australians.Read moreRead less

Summary
The inability of muscle to utilise sugar from the blood is a major problem that contributes to obesity and Type 2 diabetes. Since the number of people with these diseases will at least double by 2030, we need to find out what causes this problem. We will examine whether two muscle proteins that are impaired in obesity and Type 2 diabetes are also responsible for impaired sugar utilisation. We think that increasing these muscle proteins will fix the _sugar problem�, and remedy these diseases.

Peripheral quantitative computed tomography facility for analysing bone material and structural properties. We aim to establish a facility that allows non-invasive measurement of apparent material and structural properties of small animal and human bone using leading-edge technology, peripheral quantitative computed tomography (pQCT). pQCT measurements, incorporated into our fundamental bone research will improve our understanding of the role of mechanical, environmental and local factors in re ....Peripheral quantitative computed tomography facility for analysing bone material and structural properties. We aim to establish a facility that allows non-invasive measurement of apparent material and structural properties of small animal and human bone using leading-edge technology, peripheral quantitative computed tomography (pQCT). pQCT measurements, incorporated into our fundamental bone research will improve our understanding of the role of mechanical, environmental and local factors in regulating bone and mineral metabolism and altering bone properties. This has implications for maximising bone strength and promoting optimal health throughout life. The facility will be used for a diverse range of multidisciplinary basic bone research and is vital in order to maintain international competitiveness in the field.Read moreRead less
Central Representation of Electroacoustic Stimuli. Cochlear implantation, initially only provided to profoundly deaf individuals, is now routine in people with substantial residual hearing. Although stimulation via a cochlear implant and hearing aid in the same ear has been shown to improve speech understanding, particularly in noise, and to increase the aesthetic quality of sound, almost nothing is known about the physiological mechanisms underlying these benefits. The broad aim of our project ....Central Representation of Electroacoustic Stimuli. Cochlear implantation, initially only provided to profoundly deaf individuals, is now routine in people with substantial residual hearing. Although stimulation via a cochlear implant and hearing aid in the same ear has been shown to improve speech understanding, particularly in noise, and to increase the aesthetic quality of sound, almost nothing is known about the physiological mechanisms underlying these benefits. The broad aim of our project is to address this deficiency by measuring the patterns of neural activity evoked by speech sounds across the tonotopic axis in the inferior colliculus and auditory cortex and assess the extent to which the pattern of neural activity allows discrimination between the different speech sounds.Read moreRead less

There are a number of concerning trends in reproductive health. Women are reporting difficulty conceiving and maintaining pregnancies; while sperm count and quality are declining in men. More concerning is the increase in reproductive cancers. Gonadotropin-releasing hormone (GnRH) antagonist and agonist have been used for decades to treat reproductive cancers (such as breast cancer and prostate cancer), infertility and precocious puberty. Kisspeptin and RF-related peptide may offer more physiological alternatives to GnRH, without detrimental side effects. We will fully explore these two newly defined and major players in reproduction and provide a physiological framework for their progression to clinical use.Read moreRead less
