Stimulant laxatives are widely used and usually very effective in the short term, but how they work is very poorly understood. Our recent work has shown that they selectively excite sensory pathways from the colon which then trigger defaecation. This points to an undiscovered mechanism that potently affects colonic sensation and motility. This is likely to be a target for new treatments for other colonic disorders such as Irritable bowel syndrome and faecal incontinence.
Irritable Bowel Syndrome (IBS) is one of the leading causes of chronic pain both world-wide and in Australia for which there is a lack of treatments. Chronic pain arises from nerve fibres in the colon wall, which fail to 'reset' back to normal following inflammation. Targeting these nerve endings with drugs is a key advance in IBS treatment. This project will identify selective oxytocin analogues that act in the colon to lower pain in sensory nerves thus providing efficacious pain relief in IBS.
Development And Evaluation Of Novel Anti-inflammatory Products Derived From An Indigenous Medicinal Plant

Summary
This collaborative project between researchers at the University of South Australia and Indigenous traditional owners from Northern Kaanju homelands (Cape York Peninsula, Qld) will develop and evaluate products derived from the Northern Kaanju medicinal plant Dodonaea polyandra. Extracts of the plant and novel compounds isolated from it have anti-inflammatory activity. These have the potential to be used in inflammatory diseases such as dermatitis, arthritis and inflammatory bowel disease.
The emotional construction of self representation. This project develops and defends the novel idea that self representation is an artefact of emotional processing. The account will involve case studies of psychiatric disorder characterised by developmental or acquired problems of self representation such as depersonalisation disorder and personality disorders.
The ownership of minds. This project aims to research the awareness of a conscious state as the subject's own. This is at the heart of a perennial debate about consciousness: whether we are aware of our conscious states as our own, or are merely aware of their occurrence. The project will collaborate internationally and across disciplines and institutions to develop a conceptual distinction between two components of consciousness. It will also provide an analysis of the nature of three mental di ....The ownership of minds. This project aims to research the awareness of a conscious state as the subject's own. This is at the heart of a perennial debate about consciousness: whether we are aware of our conscious states as our own, or are merely aware of their occurrence. The project will collaborate internationally and across disciplines and institutions to develop a conceptual distinction between two components of consciousness. It will also provide an analysis of the nature of three mental disorders in which the two components seem to come apart. These outcomes are expected to constitute a significant innovation in the study of consciousness and, more generally, in the philosophy of mind.Read moreRead less
The truth about false memory. This project is aimed at determining whether reports of long-forgotten episodes of sexual abuse arising during psychotherapy should be regarded as memories or not. This issue hinges on a number of conceptual questions about memory. The project will illuminate the debate on recovered memories of sexual abuse by addressing those questions.
New Methodology for the Stereoselective Construction of Oxygen Heterocycles and Rare Sugar Analogues. The overall goal of this research is to develop new synthetic methods, particularly ones that exhibit high levels of stereocontrol. Current research efforts are directed towards the stereoselective construction of oxygen heterocycles and rare sugar analogues both in their racemic and chiral forms utilising 1,2-dioxines containing tethered hydroxyl moieties as the key chemical precursors. It is e ....New Methodology for the Stereoselective Construction of Oxygen Heterocycles and Rare Sugar Analogues. The overall goal of this research is to develop new synthetic methods, particularly ones that exhibit high levels of stereocontrol. Current research efforts are directed towards the stereoselective construction of oxygen heterocycles and rare sugar analogues both in their racemic and chiral forms utilising 1,2-dioxines containing tethered hydroxyl moieties as the key chemical precursors. It is envisaged that these investigations will lead to the development of simple experimental protocols for the synthesis of new bioactive organics.Read moreRead less
Predicting Drug-drug Interactions Due To Tyrosine Kinase Inhibitors: Inhibition Of Drug Metabolising Enzymes And Transporters

Summary
Tyrosine kinase inhibitors (TKIs) are a new class of anticancer agents. Cancer patients typically receive multiple drugs, for the treatment of cancer and other diseases, increasing the probability of interactions between coadministered drugs. Despite the widespread use of TKIs, their potential to cause drug interactions is poorly understood. Using novel in vitro approaches, this project will identify drug interactions precipitated by TKIs thereby improving drug efficacy and patient safety.
The recovery of Cu from chalcopyrite-pyrite containing concentrates, ores and tailings. Chalcopyrite, a major source of Cu, is often associated in ores with the valueless mineral pyrite. The development of more efficient methods for the retrieval of the Cu is of considerable economic importance to Australian minerals processing companies. We aim to develop methodologies allowing the more efficient :
- separation of chalcopyrite and pyrite;

Chalcopyrite, a major source of Cu, is often associated in ores with the valueless mineral pyrite. The development of more efficient methods for the retrieval of the Cu is of considerable economic importance to Australian minerals processing companies. We aim to develop methodologies allowing the more efficient :
- separation of chalcopyrite and pyrite;
- leaching of Cu from ores and tailing in a heap leach environment and
- leaching of Cu in a concentrated chalcopyrite-pyrite reactor environment.
These aims will be achieved via an integrated surface-solution speciation approach allowing the manipulation of surface properties.
