The disease causes substantial human morbidity and mortality worldwide, and is endemic in Australia. Currently available drugs are poorly effective against the parasite and treatment of the disease relies mainly on surgical removal of often large parasitic cysts, where this is possible. Blood tests to identify people who are infected rely on the use of parasite samples obtained from animals, which leads to difficulties with adequate supply of material and quality control. Research in this laboratory discovered that the hydatid parasite produces a protein that binds the drug cyclosporin A and that specific antibodies are made to this protein in hydatid patients. Preliminary research by others found that cyclosporin A had anti-parasitic effects on hydatid disease in an animal model system. This research project will examine in detail the characteristics of the cyclophilin protein and related proteins, in the hydatid parasite, their interaction with cyclosporin A, the effects of cyclosporin A on the parasite in defined culture conditions, the mechanism by which cyclosporin A exerts anti-parasitic effects and the prospects for use of cyclophilin in tests for the diagnosis of human hydatid disease. The research will contribute to a better understanding of the basic biology of this pathogen and may identify improved methods for the chemotherapy and diagnosis of infection.Read moreRead less

Summary
Chlamydia is a common sexually transmitted infection (STI) caused by the bacterium, Chlamydia trachomatis (CT). Annually, 50 million new cases of chlamydia are estimated to occur worldwide which if untreated, can lead to serious complications such as pelvic inflammatory disease and infertility in women and epididymitis in men. Over the past decade, there has been a sharp increase in diagnoses of chlamydia in Australia, coinciding with a reported upsurge in sexual risk behaviour (increased partne ....Chlamydia is a common sexually transmitted infection (STI) caused by the bacterium, Chlamydia trachomatis (CT). Annually, 50 million new cases of chlamydia are estimated to occur worldwide which if untreated, can lead to serious complications such as pelvic inflammatory disease and infertility in women and epididymitis in men. Over the past decade, there has been a sharp increase in diagnoses of chlamydia in Australia, coinciding with a reported upsurge in sexual risk behaviour (increased partner numbers and-or practices of unprotected sex), particularly among men who have sex with men (MSM). In addition, there are current outbreaks of an invasive CT strain, causing lymphogranuloma venereum (LGV), throughout Western Europe, with cases now reported in the USA. LGV can lead to severe anogenital ulcers, which can increase transmission of HIV, hepatitis C, and other STIs. With growing international travel, the likelihood of LGV outbreaks in Australia, particularly in MSM, is increased. Recently, isolated cases of LGV have been noted in MSM attending Sydney and Melbourne Sexual Health Centres, indicating LGV is possibly already in circulation. Since we know little about circulating CT types in Australia it would be difficult to assess the burden of an LGV outbreak. Due to increasing CT infections and likely risk of increased HIV transmission, particularly with LGV strains, surveillance of CT genotypes in Australia, especially in MSM, is important. The purpose of this study is to type CT strains in our population by looking at their genetic makeup. CT-positive specimens from Melbourne and Sydney will be used to identify CT types in circulation and to assess if LGV types are present. The knowledge obtained from this study will be novel and invaluable, and could contribute considerably to the development of improved disease prevention and intervention strategies, including the design of vaccines.Read moreRead less

The project is divided into three parts. In the first part of the project, the research team will identify further novel disease genes, some of which they are already close to finding. In the second part of the project the team will determine how the mutations they have identified in the disease genes actually cause the diseases. The aim of this work is to discover targets that may ultimately lead to new therapies for these muscle diseases. In the third and final part of the project, the team will pursue one possible therapeutic approach, which is based upon the understanding of the diseases the researchers have gained from their previous studies. There are currently no cures for these muscle diseases, though symptoms can be treated. The team will determine whether heart actin can replace muscle actin in skeletal muscle and thus might treat the muscle disease.Read moreRead less

Summary
Skin cancer is the most common cancer in Australia, with an estimated 375,000 people being treated for some skin cancer in Australia in 2002, and 1462 dying from the disease (mainly from melanoma) in 2001. Australia has the highest rate of skin cancer, both melanoma and non-melanoma is the world. However, if detected early, skin cancer is curable, and the focus of current treatment programs internationally is to detect the disease before it progresses to an advanced stage.

Australia has the highest rate of skin cancer, both melanoma and non-melanoma is the world. However, if detected early, skin cancer is curable, and the focus of current treatment programs internationally is to detect the disease before it progresses to an advanced stage. A large proportion of skin cancers are first detected by the non-medical community. However, due to the two-tiered medical system in Australia, a person first seeks medical opinion from a general practitioner (GP), who acts as a gatekeeper for further treatment from a specialist. Therefore the ability of GPs to be able to discern which lesions require further treatment is crucial, both for the patient, and the financial burden on the health system. A recent development has been the establishment of dedicated primary skin care clinics, which offer open access consultations to the community for the diagnosis and treatment of skin cancers and pigmented lesions. The emergence of these clinics has created much debate in the medical media. Concern has been expressed about the skills of practitioners in these clinics, whilst others argue that sub-specialisation in primary care will lead to improvements in the management of patients. As there is currently no data on the volume, casemix and diagnostic accuracy of these clinics it is difficult to assess the diagnostic ability of skin cancer clinics. This will be the first project to quantify the role of skin clinics in the diagnosis of skin cancer in the community, and in particular their case volume, casemix and diagnostic accuracy, and assess these measures in relation to a comparable sample of general practitioners. Queensland is an ideal location for a study of this type due to its high incidence of both types of skin cancer.Read moreRead less

Summary
The next generation of medical diagnostics and discovery in disease research will involve the marriage of PCR, a tool used to amplify large amounts of DNA from small starting quantities, and �next generation� sequencing, a way to sequence lots and lots of DNA on a single instrument run. This study aims to describe methods which allow scientists to screen hundreds of disease genes in hundreds of people simultaneously with high accuracy and high efficiency.

A brain biopsy is usually needed to make a definite diagnosis and may cause sequelae or not be possible if the lesion is in certain areas of the brain. Magnetic resonance imaging (MRI) has increased our ability to detect brain lesions but cannot unequivocally diagnose the disease process. Magnetic resonance spectroscopic (MRS) methods report on the chemical composition of lesions and can provide a simultaneous picture of the location of the lesion and the pathology of the disease process. Brain biopsies may therefore be avoided in a significant number of cases where drainage or decompression of lesions are not needed as part of therapy. Identification of specific fingerprints for the different diseases will provide a rapid, robust, automated diagnosis, which will expedite management decisions and improve patient outcomes. It should also be possible to monitor the efficacy of drug treatments using MRS methods. Each of these outcomes would constitute a major medical advance.Read moreRead less

Summary
We will use ocular motor technology to investigate motor dysfunction in autism and Asperger's disorder, to advance our understanding of the neurobiological bases of these disorders. This will help clarify whether neural networks are differentially disrupted in these disorders, as our previous clinical research suggests. This dissociation and the subsequent development of an ocular motor clincal screen may improve diagnosis, and potentially treatment, of these devastating conditions.
