Summary
Duchenne muscular dystrophy (DMD) is the most common and severe form of muscular dystrophy. Dystrophic muscles are fragile, prone to injury, and regenerate poorly after damage. Defective calcium handling has been implicated in these processes. We have revealed that upregulating levels of stress proteins called _heat shock proteins� (HSPs) can improve calcium regulation in muscular dystrophy. Modulating the HSP response has significant potential to delay the onset or slow the progression of DMD.
Understanding The Human Hand In Grasping And How This Changes After Stroke

Summary
The hand allows remarkable feats of dexterity. But, paralysis of the hand severely limits daily activities and is common after stroke. We will determine key mechanisms that control the hand at the level of the brain and spinal cord. We will assess some limits that develop in the muscle itself. Stroke patients will be tested so that we can better understand the brain�s control of the hand and use this to enhance recovery of hand performance in those with impaired function.
Is Sympathetic Activation Beneficial Or Detrimental In Septic Shock?

Summary
Septic shock is a major cause of death in intensive care units. It is associated with large increases in sympathetic nerve activity to the heart and kidneys, which have both beneficial and harmful effects. This project will determine the responses to the increased sympathetic activity in septic shock, the causes of it and whether blocking this activation has an overall beneficial effect. This knowledge is essential before drugs that block sympathetic activation are examined in clinical studies.
Investigation Of The Influence Preterm Birth On Lung Structure And Function In School Age Children.

Summary
Bronchopulmonary dysplasia (BPD) remains the most significant chronic lung complication of premature birth. While some information on the long term respiratory outcomes in BPD exist there are no comprehensive studies linking lung structure, function and respiratory symptoms and relating these changes to neonatal history. Studies of this kind are essential to ensure future healthcare for these children can be planned accordingly.
The Role Of The Intestinal Epithelium In Gliadin Peptide Influx In Coeliac Disease

Summary
Food products made from cereals such as wheat are part of the staple diet for much of the world but unfortunately they trigger coeliac disease in 1:100 individuals including more than 100,000 Australians. This project aims to determine where the disease inducing proteins cross the cells that line the intestine to enter the body. It also aims at increasing the health of these cells to produce a barrier that can prevent the disease inducing proteins from entering the body.
Cognitive Function And Fatigue In Cancer Patients After Chemotherapy

Summary
Many patients complain of tiredness after chemotherapy and some experience problems with memory, concentration, thinking and other aspects of mental function. Studies have confirmed that some women with breast cancer suffer these effects after chemotherapy and that they can last a long time. Although generally subtle they can affect quality of life and ability to function. Little is known about the causes of these side-effects. Possible causes include blood clotting in small vessels of the brain ....Many patients complain of tiredness after chemotherapy and some experience problems with memory, concentration, thinking and other aspects of mental function. Studies have confirmed that some women with breast cancer suffer these effects after chemotherapy and that they can last a long time. Although generally subtle they can affect quality of life and ability to function. Little is known about the causes of these side-effects. Possible causes include blood clotting in small vessels of the brain and release of molecules called cytokines, as a result of chemotherapy. Hormonal changes and induced menopause might also contribute to these effects in women. Here we propose to evaluate men and women who either receive chemotherapy to prevent recurrence of colorectal cancer, or who are followed without such treatment after surgery. Patients will complete a questionnaire that assesses their level of fatigue and participate in tests of mental functioning, before, during and at intervals after treatment. Possible causes of fatigue and cognitive problems will be studied by measuring products in the blod that indicate blood clotting, levels of cytokine molecules that might cause these symptoms and levels of sex hormones in both men and women. This may lead to further studies to help reduce the burden of fatigue and cognitive impairment from chemotherapy. The goals of our study are to provide comphrehensive information about important side-effects of cancer treatment and to examine the mechanisms that may cause them. This information is important for supporting people living with cancer and for subsequent research to develop interventions that will promote healthy lifestyles during and after treatment for cancer.Read moreRead less
