Summary
Scientific evidence indicates that low concentrations of silver are effective in countering bacteria involved in dental decay, and that solutions of silver fluoride are effective in stopping progression of dental decay. This study aims to determine the effectiveness of low strength silver fluoride solutions in the clinical management of dental decay in children. Such solutions may provide a simplified technique for controlling dental decay in populations which lack traditional resources
Femoroacetabular impingement (FAI) is a common cause of hip pain characterised by extra bone formation at the hip, called a cam-deformity. FAI is thought to create hip joint damage and osteoarthritis. Our 5 year longitudinal study of people with FAI in two (Melbourne and Brisbane) sites will investigate whether factors (such as cam-deformity size, hip contact force, muscle strength and joint range) can predict hip joint damage (measured with magnetic resonance imaging) over two years.
Discrete Simulation Of Powder Dispersion In Pharmaceutical Aerosol Inhalers

Summary
This project seeks to develop fundamental understanding of the dispersion mechanisms of powders as aerosol for inhalation drug delivery. It couples computational simulations using computational fluid dynamics and discrete element method with experimental dispersion analysis. Successful development of this research will lead to a comprehensive understanding of factors controlling inhaler performance and thus maximizes the therapeutic benefits to the patients.

Osteoporosis is a condition in which the skeleton becomes fragile and susceptible to fractures. It is a public health problem that affects both men and women over the age of sixty. Although osteoporosis affects the elderly, the most opportune time to prevent osteoporosis may be during childhood. Physical activity is a lifestyle factor known to affect the strength of the skeleton. Bone density is commonly used as a measure of bone strength because it is easily measured and is related to the break ....Osteoporosis is a condition in which the skeleton becomes fragile and susceptible to fractures. It is a public health problem that affects both men and women over the age of sixty. Although osteoporosis affects the elderly, the most opportune time to prevent osteoporosis may be during childhood. Physical activity is a lifestyle factor known to affect the strength of the skeleton. Bone density is commonly used as a measure of bone strength because it is easily measured and is related to the breaking strength of bones. However changes in the shape of bones can also affect bone strength with or without an increase in bone density. Changes in bone shape in response to exercise in children or adults have rarely been investigated, and little is known about the effects of exercise on bone shape during different stages of growth. This study is the first to investigate how exercise during childhood may affect bone strength by changing bone shape. 45 elite female tennis players aged between 6 to 18 years have completed two years of this study. 90 novice and competitive male tennis players aged between 6 to 20 years and 60 healthy age matched controls will be asked to participate in this study. Measurements will be made annually for three years. The bone shape and density of the dominant and non-dominant arms of the players will be compared with the children who don't play tennis - comparisons will also be made between i) different stages of puberty and ii) girls and boys. The findings of this study are important because the lifestyle of children today may predispose them to a greater risk of osteoporosis late in life. Physical activity may be the most important modifiable protective factor against fragile bones in old age. The findings of this study will be the first to provide insight into whether there is a unique time during growth when exercise will result in the greatest increase in bone strength by changing bone shape.Read moreRead less
BRAIN Training Trial: Balance, Resistance, Or INterval Training Trial: A Randomised Controlled Trial Of Three Exercise Modalities In Mild Cognitive Impairment

Summary
About 10% of older adults have mild changes in memory or thinking (Mild Cognitive Impairment, or MCI) which don’t interfere with daily life, but increase the risk of dementia. Exercise may improve thinking abilities, but the best kind of exercise is not clear. We will randomise 530 older adults with MCI in Australia, Canada, and Israel to weight lifting, high intensity aerobic training or toning exercises for 12 months to see which prescription is best for brain health and overall function.
Effective Strength Training For Walking In Neurological Rehabilitation

Summary
Muscle weakness is the cause of walking problems following neurological problems such as stroke and brain injury. Many studies have used strengthening exercises but few have benefitted. It appears that clinicians have been strengthening the wrong muscle groups and have not used exercises that stimulate the muscles to work the way they do when walking. The aim of this project is to use well established biomechanical and strengthening guidelines to improve walking after neurological injury.
