Non-invasive Near-infrared Optical Imaging Of Neurodegeneration

Funding Amount
$312,033.00
Summary
Dementia currently affects over 240,000 Australians with an increasing health cost. A common cause of dementia occurs when proteins in the brain form deposits and brain cells degenerate and die. This project will develop a novel medical imaging method that will facilitate the detection of dying brain cells. This will enable a better understanding of the causes of cell death and the opportunity to identify the best time for meaningful therapeutic intervention.
Molecular Epidemiology And High Resolution Surveillance Of Salmonella Enterica Serovar Typhimurium In Australia
Funder
National Health and Medical Research Council
Funding Amount
$583,180.00
Summary
Salmonella typhimurium is a leading cause of the food-borne disease – salmonellosis. It is responsible for considerable morbidity and has an enormous economic cost. Molecular typing is the key to rapidly identify and control outbreaks. This project will employ next generation sequencing technology to develop a new molecular typing scheme. A surveillance system that integrates molecular typing data and epidemiological data will be developed for outbreak investigation and disease prevention.
Understanding The Roles Of Dendritic Domains In Neuronal Function

National Health and Medical Research Council
Funding Amount
$491,509.00
Summary
We aim to find cellular basis to cognitive function and dysfunction by understanding the input/output characterstics of individual neurons. Since neurons are fundamental computational units in the brain, we aim to understand how synaptic inputs to different dendritic regions are processed prompting the neuron to fire an output. We also aim to seek distinct roles of certain dendritic branches in gating sensory inputs onto the neuron.
Epigenetic Determination Of Neuronal Vulnerability And Neurodegenerative Disease

Funding Amount
$617,857.00
Summary
Neurons are faced with diverse forms of stress everyday. Neural diseases exacerbate this stress, causing interference to genes that normally allow neurons to function correctly. As a result, neurons die, and severe loss can result in diseases such as dementia. We have discovered new molecular factors in neurons that insulate their genes from stress, thereby protecting neuron function and health. The proposed research will exploit these mechanisms to better protect neurons from disease.
Optimising Temporal Genomic Surveillance Of Salmonella Infections In Australia

Funding Amount
$763,447.00
Summary
Salmonella is a leading cause of the food-borne disease – salmonellosis. It is responsible for considerable morbidity and has an enormous economic cost. Molecular typing is the key to rapidly identify and control outbreaks. This project will optimise the use of whole genome sequencing for outbreak investigation and long term epidemiology. A surveillance system that integrates genome sequence and epidemiological data will be highly significant for outbreak investigation and disease prevention.
To Investigate The Role Of ATM Protein In Protecting Against Neurodegeneration

Funding Amount
$953,662.00
Summary
The overall aim of the project is to employ a rat model to investigate neurodegeneration in patients with ataxia-telangiectasia (A-T). Ataxia-telangiectasia is a complex multisystem disorder characterised by progressive neurological impairment, variable immunodeficiency and cancer predisposition. The rat model recapitulates the neurodegeneration in patients and thus this project will provide important insight into the nature of the defect as well as approaches for the treatment of the disorder.
Micro-elastography - A New Tool For Microscopic Intraoperative Tumour Margin Assessment In Breast Cancer

$195,956.00
Summary
In breast cancer surgery, it is vital to completely remove the entire tumour. Unfortunately, in 30% of breast-conserving surgeries, re-excision is required because microscopic analysis after the surgery indicated some tumour had been missed. This has traumatic consequences for the patient and places a huge economic burden on the healthcare system. Using micro-elastography, we will enable the surgeon to detect small regions of tumour during the initial surgery. This probe may significantly reduce ....In breast cancer surgery, it is vital to completely remove the entire tumour.

The Role Chromatin Remodeling Factors In Epigenetic Regulation Of Cardiac Arrhythmia

Funding Amount
$854,135.00
Summary
Cardiovascular diseases kill an Australian every 11 minutes. Arrhythmias are of particular alarm since they can lead to significantly higher risk of serious strokes, heart failure, and overall mortality. We combine fruit fly genetics with next generation human genomics approaches to find and functionally validate new genes and mutations regulating arrhythmia in fruit flies and atrial fibrillation in humans, and this work can rapidly identify new avenues to pursue therapeutic intervention
Functional Dissection Of The Malaria RhopH Complex And Its Contribution To New Permeation Pathways
Funder
National Health and Medical Research Council
Funding Amount
$604,718.00
Summary
The ability of Plasmodium to invade and remodel its host erythrocyte are the most significant contributors to its ability to cause the disease malaria. This project aims to understand how proteins secreted from a specialized rhoptry organelle during erythrocyte invasion help Plasmodium to remodel the erythrocyte so that the parasite can gain access to the vital nutrients it requires for survival. This research will validate whether drugs targeting the rhoptry proteins are viable drug targets.
EEF1A1 Is Critical For HIV-1 Reverse Transcription And Replication

National Health and Medical Research Council
Funding Amount
$521,429.00
Summary
The project will investigate interaction between the AIDS virus, HIV-1, and the human cell it grows in specifically focusing on a human protein called eEF1A. Our research shows eEF1A is required for HIV-1 growth by regulating a step in the virus life cycle called reverse transcription. The goal of this project is investigate how interaction with eEF1A helps HIV-1 reverse transcription and to find drugs that block HIV-1 interaction with eEF1A.
