Stem Cell Bioinformatics For Eye Research: Mapping An Integrative Network Model Of Glaucoma

Summary
Biology has become data-driven, with a huge amount of data available but not enough researchers with bioinformatics skills to analyse it. By studying genetic architecture of eye cells generated from induced pluripotent stem cells of individuals with and without glaucoma, I aim to contribute to a better understanding of the underlying causes of glaucoma and equip myself with new bioinformatics skills to utilise in future eye research in Australia.

Summary
Primary open angle glaucoma is a chronic eye disease and one of the leading causes of visual impairment and blindness worldwide. This study will use cutting-edge genetic methods to look at the entire coding component of the human genome (exome) in 271 individuals from large glaucoma families. Our previous studies have shown that these families carry genetic variants that increase disease risk. In this investigation we aim to identify these genes, with the hope they may offer novel targets for tr ....Primary open angle glaucoma is a chronic eye disease and one of the leading causes of visual impairment and blindness worldwide.

Summary
A 25 fold increase in the risk of going blind on diagnosis of diabetes is one of the most daunting threats that patients face. Most cases of vision impairment in diabetes are due to macular oedema that persists or recurs after laser treatment. There are now a number of uncontrolled, anecdotal reports that intravitreal triamcinolone (IVTA) is highly effective for the treatment of diabetic macular edema which is refractory to conventional laser treatment.

Most cases of vision impairment in diabetes are due to macular oedema that persists or recurs after laser treatment. There are now a number of uncontrolled, anecdotal reports that intravitreal triamcinolone (IVTA) is highly effective for the treatment of diabetic macular edema which is refractory to conventional laser treatment. We commenced the first placebo-controlled, double masked clinical trial of intravitreal triamcinolone for refractory macular oedema in 2002. The 3 month results from this study provide the first scientific proof of principle that intravitreal triamcinolone reduces macular thickness and improves vision. The two year results will be available in March 2005, but confidential interim analysis of efficacy data in September 2004 suggested that the beneficial effect of triamcinolone treatment persisted. Thus it appears that treatment with intravitreal triamcinolone may be the most significant development for the prevention of blindness in people with diabetes since the introduction of laser treatment. It would also be a highly cost-effective intervention that could be administered by general ophthalmologists. The treatment cannot be recommended for routine use, however, until its long term efficacy and safety have been established. Since we already have a well studied group of patients who have received treatment for 2 years, we are in a unique position to extend the study in order to provide the long-term (5-year) safety and efficacy data that does not appear to be forthcoming from any other source. The results of this study will significantly improve knowledge of long-term outcomes of local high dose steroids for diabetic macular oedema, allowing the treatment to be used more rationally. Thus the study is very likely to directly reduce the risk of blindness in people with diabetes.Read moreRead less
AUSTRALASIAN MULTICENTRED PROSPECTIVE RANDOMISED STUDY OF LAPAROSCOPIC VS CONVENTIONAL SURGICAL TREATMENT OF COLON CA
Funder

Funding Amount

Summary
Colon cancer is one of the most common solid tumours in western society. The usual initial treatment is excision of the cancer by an operation done through a cut down the midline of the abdominal wall. Over the past 10 years, minimally invasive technology has changed the approach to many surgical operations. A good example of this is an operation to remove the gall bladder. This is now routinely done using a laparoscope (telescope) which is introduced at the umbilicus.

Over the past 10 years, minimally invasive technology has changed the approach to many surgical operations. A good example of this is an operation to remove the gall bladder. This is now routinely done using a laparoscope (telescope) which is introduced at the umbilicus. An image on a video screen of the gall bladder is then used to guide instruments to remove the gall bladder without making a large incision in the abdominal wall. This is called a laparoscopic cholecystectomy. The safety of a laparoscopic assisted approach in the removal of colon cancer is yet to be determined. This study will compare the long term and short term outcomes of people who have colon cancers removed either by a laparotomy (a cut in the midline of the abdominal wall) or by a laparoscopic assisted approach (telescope).Read moreRead less

New, Efficient Tests That Map Both Central and Peripheral Vision. This project seeks to develop a new, combined approach for quantifying both central and peripheral vision with a single test. Current methods for testing far peripheral vision are not efficient and not fully automated. Yet peripheral vision is important for tasks involving navigation and hazard avoidance such as driving. The project intends to invent and test new approaches to sampling and measuring the spatial extent of vision. T ....New, Efficient Tests That Map Both Central and Peripheral Vision. This project seeks to develop a new, combined approach for quantifying both central and peripheral vision with a single test. Current methods for testing far peripheral vision are not efficient and not fully automated. Yet peripheral vision is important for tasks involving navigation and hazard avoidance such as driving. The project intends to invent and test new approaches to sampling and measuring the spatial extent of vision. The anticipated algorithms will be more accurate and efficient than current tests, will be suitable for older adults, and will enable ready assessment of vision for occupational tasks.Read moreRead less
The Contribution Of Upstream Open Reading Frames To The Eukaryotic Proteome

Funding Amount

Summary
This project will investigate the novel idea that genomes of complex organisms (including human) 'double-dip' with many genes containing information for more than one protein. It will also examine if these small supernumary proteins have cell regulatory functions. If proved, it would significantly alter current views on the information content of higher vertebrate genomes. An understanding of the roles of these novel protein sequences may result in the development of new drugs.
Exploiting high resolution images of the retina to customise vision tests. This project will make vision tests more accurate and faster by using a person's individual eye anatomy to customise the test. The basic understandings discovered in this project are expected to be applied in clinical and research settings thus saving sight, dollars and time.

The project will deliver a general methodology for developing formal logical specifications of the Acts of Parliament for many common systems for counting votes in preferential elections. The project will deliver corresponding computer programs to count votes according to these systems and will deliver formal independently checkable proofs that the programs meet their specification. Such formally verified computer programs provide a legally sound basis for counting votes by computer. The methodology will also allow electoral commissioners to improve the natural language descriptions of the relevant Acts of Parliament which are often woefully out of date with current practice.Read moreRead less
