Summary
Intestinal mucositis is a serious disorder associated with chemotherapy treatment in cancer patients. Recently, a new strain of probiotic bacteria has been described with the potential to decrease the severity of intestinal mucositis. However, it is not known whether the live probiotic is necessary for this effect. We will compare the live probiotic, dead probiotic and factors sourced from this probiotic for the potential to decrease the severity of intestinal mucositis. Similarly, there have be ....Intestinal mucositis is a serious disorder associated with chemotherapy treatment in cancer patients. Recently, a new strain of probiotic bacteria has been described with the potential to decrease the severity of intestinal mucositis. However, it is not known whether the live probiotic is necessary for this effect. We will compare the live probiotic, dead probiotic and factors sourced from this probiotic for the potential to decrease the severity of intestinal mucositis. Similarly, there have been anecdotal claims of medicinal application for so-called ‘bioactive’ extracts and formulations derived from a range of mammalian, marine and plant sources. Specifically, Lyprinol (an extract derived from the New Zealand Green-Lipped Mussel), Emu Oil (derived from Emu meat) and the herbal extract Iberogast, have been reported to possess antiinflammatory properties. Indeed, these agents are used widely for the adjunctive relief of symptoms associated with arthritis and joint pain. However, these agents have yet to be tested for their potential to treat or prevent intestinal mucositis. For the first time, utilizing proven, controlled animal model systems, the current submission will explore the therapeutic potential of these agents, alone and in combination with indicated probiotics, for their capacity to treat or prevent mucositis. Should efficacy be demonstrated, a potential mechanism of action will be sought by investigating effects on intestinal stem cells.Read moreRead less
The Effects Of The Western Diet On Cognition In Rats

Summary
An unhealthy diet can affect how we think. This project will identify mechanisms by which a western diet impairs cognition, and test ways of intervening to reduce the impact of diet on the brain. We will examine changes in inflammation, and markers of nerve growth in a critical brain region, the hippocampus, in response to different periods of diet. We will also test if the diet and our interventions affect the gut biota.
Mnemonic Segregation: Understanding The Neural Circuitry Of Parkinson’s Disease Dementia.

Summary
To investigate neural circuitry allowing distinct memories to co-exist while minimising interference. Dementia involves a breakdown of this system, where memories are no longer segregated or tagged by environmental features. I also aim to find behavioural techniques which allow memories formed in therapy to generalise to patients’ home environments. By understanding the process of segregating memories we can develop interventions where this fails and manipulate it to improve clinical practice.
