There are 140 million contact lens wearers worldwide. Use of contact lenses is associated with ocular inflammation (approximately 2-7% per year). We have developed novel antimicrobial coatings for contact lenses which we have shown in laboratory and animal models can reduce the ability of microbes to adhere to lenses and reduce associated inflammation.

The Impact Of Pseudomonas Aeruginosa Biofilm On Eye Infection And The Development Of Antimicrobial Contact Lenses
Funder

Funding Amount
$328,932.00
Summary
Worldwide, 125 million people correct their vision through the use of contact lenses. Contact lens use predisposes the wearer to sight threatening eye infections. Despite advanced material technology and improved hygiene regimens, the rate of contact lens-related infectious disease has remained constant. This research aims to elucidate how bacteria compromise the ocular immune system in order to develop preventative/therapeutic strategies to combat ocular infections.

Summary
Sunlight is an important environmental health hazard as it causes immunosuppression and cancer. It suppresses our ability to destroy developing cancers. Australia has the highest incidence of skin cancer in the world, 66% of Australians develop skin cancer during their lifetime. The relationship between UV dose, wavelength and cancer in humans is unknown. As this cannot be directly experimentally determined in humans, surrogate biological endpoints such as immunosuppression will help determine t ....Sunlight is an important environmental health hazard as it causes immunosuppression and cancer. It suppresses our ability to destroy developing cancers. Australia has the highest incidence of skin cancer in the world, 66% of Australians develop skin cancer during their lifetime. The relationship between UV dose, wavelength and cancer in humans is unknown. As this cannot be directly experimentally determined in humans, surrogate biological endpoints such as immunosuppression will help determine the damaging wavebands within sunlight. There has been little work on the effect of UVA on health or the mechanisms of action of UVA compared to UVB. A recent consensus UVA working group of 80 international participants convened by the American Academy of Dermatology out of concern about the lack of knowledge of UVA on human health concluded that the action spectrum for photocarcinogenesis and photoageing, particularly the efficacy of UVA in humans remains to be elucidated, and that more funding should be provided for radiation biology research to help elucidate UVA mechanisms of injury. Similarly a recent expert meeting (including Prof. Halliday) convened by the International Agency for Research on Cancer (WHO) on sunscreen protection from skin cancer recommended that studies should be conducted on the effects of exposure to UVA in causing both photoageing and skin cancer which followed from their major recommendation that it is important to understand the nature of the dose-response relationship on risk and the action spectrum for each effect . The studies described in this project will contribute to these recommendations.Read moreRead less
Factor XII Dependent Coagulation, Thrombin And Platelet Glycoprotein 1ba In Arterial Thrombosis And Bleeding Disorders

Summary
Clot formation is the key event underlying heart attacks and strokes. There is new data that Factor XII (FXII) can play an important role in clot formation-thrombosis. We aim to examine the role FXII plays in clot formation, in particular the role of FXII in thrombin generation, which is the central event of clot formation, and its interaction with platelet glycoprotein 1ba (another important molecule in thrombosis). New insights into clotting and new therapies can result from our research.
