Regulation Of Cortical Excitability By GABAB Receptors

Summary
In the brain electrical activity either excites or inhibits nerve cells. Excitation is balanced by inhibition. If these two processes become unbalanced we can become unconscious or go into seizure. These extreme conditions emphasize the importance of the balance between excitation and inhibition in the brain. While there has been much work on the role of excitation, less is known about inhibition. In this project proposal we will investigate how inhibition regulates excitation in the cortex.
Personally Controlled Electronic Health Records For Young Adults With Communication Disabilities: Charting The Course For Successful Child To Adult Health Service Transition.

Funding Amount
$400,665.00
Summary
Adolescents and young adults with chronic health conditions and communication disabilities struggle to communicate their health information with service providers. This causes problems in care when moving from child to adult health services. This study will investigate their use of the Personally Controlled Electronic Health Record as a means to support timely and effective information exchange to improve healthcare for these vulnerable young adults.
Early Indicators Of Noise Injury: Are Decreased Auditory Processing Skills Evident In Noise-exposed Adults Prior To Diagnosis Of Hearing Loss?

Funding Amount
$367,605.00
Summary
Recent research indicates that noise-exposed individuals with similar hearing thresholds to non-noise exposed counterparts are more likely to have diminished temporal and spectral auditory processing abilities. This research aims to determine the relationship between noise exposure levels and auditory processing difficulties; the influence of musical training in ameliorating these difficulties; and a neurological model of causation, operation and possible remediation of these difficulties.
Cochlear Type II Neurons In Contralateral Suppression

Summary
Sound in one ear affects hearing in the other ear. This contralateral suppression is important for hearing attention and protection from noise damage. We will test the hypothesis that cochlear type II sensory neurons provide the sensory input for this process using models where neuronal development is altered, or the neurons are removed. The study addresses hearing disability in society, facilitating cochlear prosthesis development and the understanding of hearing loss.
Cell-specific Regulation Of The MicroRNA/RNAi Pathway

Summary
MicroRNAs are a group of molecules that are critical for controlling the activity of genes. They function in a diverse range of biological systems, such the brain and immune system. Although we know that these molecules are important, how they are made in cells is still poorly understood. Because these molecules have potential therapeutic applications, it is essential that we gain a precise understanding of their biology before we will be able to apply these to medicine.
A Novel Molecular Mechanism Controlling Myelopoiesis

$878,439.00
Summary
The immune system is comprised of many different cell types, each with a specialised function. Many are short-lived and must be continually replenished throughout life. Abnormalities in this process underlie many human diseases, including immunodeficiency, autoimmunity and cancer. We have discovered a novel molecular mechanism that is critical for the production of immune cells. This project will investigate how this mechanism is controlled and the impacts on myelodysplastic syndromes.
The research will investigate the mechanisms by which our brains are able to listen selectively to sounds of interest in competing background noise. This will be investigated in normal hearing subjects, those with partial deafness and in profoundly deaf patients who use a cochlear implant. If deaf patients can learn to use cues to enhance detection of sounds of interest this could have an impact on the effectiveness of hearing aids and cochlear implants in noisy listening situations
MicroRNAs are a group of molecules that are critical for controlling the activity of genes. They function in a diverse range of biological systems, from early embryonic development to adult organs, such as the brain and immune system. Although we know that these molecules are important, there remain major gaps in our understanding of how they are produced. Thus, the goal of our research is to understand how cells make these molecules.
Defining The Role Of RNA Editing In Erythropoiesis

Summary
We are seeking to understand how red blood cells are produced. We have identified that a process called RNA editing may be important in the regulating the production of red blood cells.
Improving Patient Safety In Radiation Therapy With The Watchdog Real-time Treatment Delivery Verification System

Funding Amount
$593,742.00
Summary
Radiation therapy is a highly effective cancer treatment with extremely high doses delivered using very complex treatment machines. Unfortunately errors have occurred resulting in cases of patient death and mistreatment. We have developed a novel method to assess the treatment delivery in real-time to prevent errors. The method uses imaging devices that are already present on the treatment machine meaning that this method could have a major impact on patient safety in modern radiation therapy.
