Summary
This study tests the effectiveness and safety of a potential new treatment for depression, which involves mild stimulation of the brain, given through pads placed on the scalp. There is no anaesthetic or seizure and the treatment is painless. The treatment is given on an outpatient basis, three times per week, for 10 sessions, each session taking approximately half an hour. If found to be effective and safe, this new treatment could be an alternative to antidepressant medication.

Summary
The cause of schizophrenia is uncertain. Several lines of evidence implicate abnormalities of functioning in circuits of nerve cells in the outer brain regions. Chemicals involved in these circuits are important for the capacity to learn and process new information and repeated exposure to stimuli. To date, it has been difficult to directly test the function of these circuits in patients with schizophrenia.

Several lines of evidence implicate abnormalities of functioning in circuits of nerve cells in the outer brain regions. Chemicals involved in these circuits are important for the capacity to learn and process new information and repeated exposure to stimuli. To date, it has been difficult to directly test the function of these circuits in patients with schizophrenia. Transcranial Magnetic Stimulation (TMS) is a non-invasive means of stimulating nerve cells in superficial areas of the brain. During a TMS procedure, an electrical current passes through a coil placed close to the scalp. This current induces a magnetic field that stimulates electrical activity in nerves below the coil. TMS methods can be used to study the functioning of nerve cells in the brain and the way in which they respond to repeated stimuli. These methods will be used in this way to study the functioning of these circuits in patients with schizophrenia. This is likely to provide important information as to the function of these brain areas and may provide information that will guide the development of therapeutic interventions.Read moreRead less

Summary
Prostate cancer is a leading cause of cancer deaths in men in the Western world. Neuroendocrine cells may play an important role in the development of these cancers, but their biology is essentially uncharacterized. Activation of the cell-bound protein gp130 results in neuroendocrine differentiation, growth and chemotherapeutic drug resistance of prostate cancer cells. We will use gp130-dependent differentiation to understand how neuroendocrine cells influence normal and cancerous prostate cells ....Prostate cancer is a leading cause of cancer deaths in men in the Western world. Neuroendocrine cells may play an important role in the development of these cancers, but their biology is essentially uncharacterized. Activation of the cell-bound protein gp130 results in neuroendocrine differentiation, growth and chemotherapeutic drug resistance of prostate cancer cells. We will use gp130-dependent differentiation to understand how neuroendocrine cells influence normal and cancerous prostate cells, and to identify neuroendocrine-cell specific genes that may be of diagnostic or therapeutic benefit in prostate cancer. Gp130 can be activated by a group of hormones called the interleukin-6 type cytokines in the presence of certain cell-bound proteins (receptors). If these receptors are inappropriately expressed in the prostate, inappropriate activation of gp130 could occur resulting in prostate cancer cell growth or neuroendocrine differentiation. If we can determine that these receptors are expressed in prostate cancer, but not in non-cancerous prostate, this would have diagnostic or therapeutic benefit.Read moreRead less

Summary
Treatment Resistant Depression is clearly a major health issue - depression is common, results in marked morbidity and mortality and a large percentage of patients do not respond to, or cannot tolerate standard treatment. The development of new treatments for this condition is undoubtedly required.

The development of new treatments for this condition is undoubtedly required. International efforts are underway to try and establish the efficacy of high frequency left Transcranial Magnetic Stimulation (HFL-TMS) to the point where the technique may be approved by regulatory authorities and clinically introduced. However, clearly the response rate to HFL-TMS is suboptimal for its widespread use. The overall goal of this research program is to develop repetitive TMS (rTMS) methods to the point at which they are highly relevant and applicable to clinical practice. None of the substantial international studies is focusing on novel applications such as sequential bilateral rTMS (SBrTMS). The planned outcome of this study is that it may change the focus of rTMS application and practice nationally and internationally. If we can follow our well received initial study of this technique with a substantial comparative trial as planned here, it will provide enough evidence for the more widespread adoption and testing of SBrTMS as a viable alternative to HFL-TMS. Ultimately, this or a modification of it, may become the rTMS administration method of choice. Additionally, we will have a sufficient sample size to start to explore meaningful predictors of clinical response including biological, psychosocial-personality variable predictors.Read moreRead less
Transcutaneous Electrical Stimulation To Relieve Chronic Constipation In Children

Summary
1 in 300 children suffer from chronic constipation that is not fixed by changing their diet or taking laxatives. They continue to suffer the problem into adulthood. They also have fecal incontinence or soiling that causes problems with socialising and schooling. We are testing a method of electrical stimulation through the skin on the belly to increase the movement of the bowel. Initial results are encouraging, showing that the rate of movement of the bowel is increased and soiling is decreased.

We have a new physiotherapy technique that may overcome constipation and stop soiling in many of these children. In 2003-4, we ran a pilot study to test a technique used by physiotherapists to treat urinary incontinence. We have called the method TESIC (transcutaneous electrical stimulation using interferential current). TESIC uses suction electrodes placed on the belly and back at the level of the belly button. The electrical stimulation is applied using a current (interferential current) that stimulates deep into the abdomen. We tested 8 children and had very encouraging results with improved constipatio in 5-8 and all with soiling stopped. Parents and children are keen to use this technique but first we need to establish that the results are reproducible in a larger group of 70 children. We also need to know if the effect was just a placebo response (due to time spent with the physiotherapists), and how long the effect lasts. We will also measure changes in soiling. Faecal soiling is smelly and antisocial. Relief of soiling has a big impact on a child's ability to fit in at school and to attend normal schooling. We will measure outcomes using daily diaries kept by children, questionnaires, how quickly food moves through the bowel and pressures within the bowel. We have a multidiciplinary team of experienced clinicians and scientists with expertise in these techniques and in constipation and incontinence in children (paediatric surgeon, gastroenterologist, manometry nurse, incontinence paediatrician and physiotherapist, expert in electrical stimulation and gut nervous system scientist). This technique could revolutionise treatment of chronic constipation. Most physiotherapists have TESIC machines, allowing delivery Australia wide. It is non-invasive and should also be able to be used by adults, including the elderly in nursing homes.Read moreRead less
Harnessing Human Motor Cortical Plasticity For Performance And Rehabilitation

Summary
Motor learning allows us to interact with our environment and loss of this ability is catastrophic. The reorganisational capacity of the brain can be used to enhance recovery from brain injury. However, our ability to do so is limited by lack of understanding of the underlying mechanisms. These studies will use novel approaches to investigate how the human brain reorganises during motor skill learning. The outcomes will be important for the development of novel therapeutic approaches.
