Novel insecticidal neurotoxins from Australian spider venoms. Insecticidal toxins have considerable potential as novel biopesticides to combat the evolution of widespread insect resistance to classical chemical pesticides. This problem is increasing both in Australia and internationally. This study aims to isolate and pharmacologically characterise potent and selective insecticidal neurotoxins from Australian arachnids. Our laboratories will isolate neurotoxins from spider venoms, determine thei ....Novel insecticidal neurotoxins from Australian spider venoms. Insecticidal toxins have considerable potential as novel biopesticides to combat the evolution of widespread insect resistance to classical chemical pesticides. This problem is increasing both in Australia and internationally. This study aims to isolate and pharmacologically characterise potent and selective insecticidal neurotoxins from Australian arachnids. Our laboratories will isolate neurotoxins from spider venoms, determine their selectivity in insect and mammal bioassays, determine their primary and tertiary structures, and investigate their structure-function relationships by electrophysiological techniques. These functional and structural data will allow the future engineering, by molecular or synthetic procedures, of viral biopesticide analogues with increased potency, stability and selectivity.Read moreRead less

Targeting particulate carriers to epithelial M cells. This project aims to develop and validate an advanced in vitro model of the human intestinal epithelium. The intestine-on-chip model should enable mechanistic studies of the uptake of nano- and micron-size particles by intestinal cells and deliver new insights into the way particulate carriers can be specifically targeted and transported across the intestinal epithelium. Project knowledge and technology are anticipated to generate new commerc ....Targeting particulate carriers to epithelial M cells. This project aims to develop and validate an advanced in vitro model of the human intestinal epithelium. The intestine-on-chip model should enable mechanistic studies of the uptake of nano- and micron-size particles by intestinal cells and deliver new insights into the way particulate carriers can be specifically targeted and transported across the intestinal epithelium. Project knowledge and technology are anticipated to generate new commercialisation opportunities in the oral delivery industry and ultimately, should drive the development of efficient oral formulations for biologics. The model should also reduce the need for animal studies.Read moreRead less

Pharmacological modification of retinal and visual function and relation to control of refractive error. Myopia (short-sightedness) affects many hundreds of millions of people worldwide and can lead to blindness. Drug treatments that prevent myopia are being developed, however there is no efficient way of determining who is at risk of myopia or who will benefit from these treatments. This fundamental research project will determine the retinal and visual effects of pharmacologic agents that inhi ....Pharmacological modification of retinal and visual function and relation to control of refractive error. Myopia (short-sightedness) affects many hundreds of millions of people worldwide and can lead to blindness. Drug treatments that prevent myopia are being developed, however there is no efficient way of determining who is at risk of myopia or who will benefit from these treatments. This fundamental research project will determine the retinal and visual effects of pharmacologic agents that inhibit myopia, with the aim of determining an ocular measure that is related to myopia, which is altered by drugs that are known to slow myopia progression, and that could be used as an indication of an agent's likely effectiveness.Read moreRead less

Effective communication and improved patient safety: Addressing the complexities of managing high risk medications in metropolitan and regional hospitals. Current costs of hospital-related incidents are around AU$2 billion per year, and the most common cause of these incidents is ineffective communication. Medication incidents relating to use of high risk medications are particularly critical because of the increased severity of patient outcomes. High risk medications are administered in busy en ....Effective communication and improved patient safety: Addressing the complexities of managing high risk medications in metropolitan and regional hospitals. Current costs of hospital-related incidents are around AU$2 billion per year, and the most common cause of these incidents is ineffective communication. Medication incidents relating to use of high risk medications are particularly critical because of the increased severity of patient outcomes. High risk medications are administered in busy environments, and involve patients who are cared for by many different health professionals in technologically complex settings. These factors increase the likelihood of more medication incidents. The unique knowledge obtained will inform policies and identify strategies for better communication. Health professionals and patients can adopt these strategies to improve medication safety.Read moreRead less
