Summary
Women are protected from cardiovascular disease as compared to age-matched men, an effect lost with age. Understanding protective factors that act in females could be used to treat hypertension, heart failure and stroke in males at all ages, and maintain protection in elderly women. Our studies aim to determine if relaxin, an ovarian hormone, can promote cardiovascular health in women.
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.
Multipotent Stem Cells Derived From Postimplantation Mouse Embryos: Evaluation Of Germ Layer Differentiation Potential

Summary
This study of the properties of cells that can differentiate into specific lineages provides useful insights into the cellular and molecular mechanisms for the specification of these progenitors from the pluripotent stem cells. The procurement of tissue-specific precursor cells that are capable of self-renewing and population expansion is a critical pre-requisite for achieving directed differentiation of stem cells into therapeutically useful cells for tissue replacement and regeneration.
Prevention And Treatment Of Bone Infection With CSA-90

Funding Amount
$350,983.00
Summary
Bone infections are a major challenge to treat, especially with the rise of drug resistant “superbugs”. We have access to a new agent, CSA-90, that has dual properties of being anti-microbial (antibiotic) and helps encourage bone growth. This project aims to expand upon our prior research and test CSA-90 for the treatment of chronic bone infections. We will also look at applying this technology to joint replacements and this drug may be particularly useful for coating orthopaedic implants.
Deciphering The Metabolic And Endocrine Profile Of Healthy Adipocytes

Funding Amount
$563,194.00
Summary
Obesity is associated with the development of metabolic diseases, however, it is becoming clear that it is where the excess fat is stored that is more important when predicting the health risks associated with obesity. This project aims to identify whether adipocyte progenitor cells, which eventually become fat cells, are ‘preprogrammed’ and whether differences in these cells explain the generation of either healthy or unhealthy fat in different locations of the body.
Efficacy Of Education And Advice Delivered By Text Message To Aid Smoking Cessation

Funding Amount
$538,395.00
Summary
A high proportion of smokers indicate a desire to stop smoking and report having made attempts to quit. However, most attempts are not successful and new methods are needed to support motivated smokers and improve success rates. This project evaluates the use of text messages to deliver advice and support to smokers motivated to stop smoking. We aim to understand if and how this promosing new intervention helps smokers to quit.
Comparison Of Periodontal Ligament Stem Cells And Induced Pluripotent Periodontal Ligament Stem Cells For Periodontal Regeneration

Funding Amount
$831,955.00
Summary
In the first part of this study we will determine whether induced pluripotent stem cells or adult stem cells from the periodontal ligament are better candidates for periodontal regeneration. Secondly, using CAD/CAM technology we will make tissue engineering scaffolds tailored to fit periodontal defects and seeded with stem cells to improve on current techniques used to regenerate damaged tissues around teeth affected by periodontal disease.
Investigating Human Keratinocyte Stem Cells And Their Microenvironmental Niche

Funding Amount
$570,928.00
Summary
The stem cells in the outer protective layers of the epithelium of the skin (keratinocyte stem cells), possess an intrinsically high capability to regenerate tissue. However, this tissue regenerative ability can be enhanced by interactions with microenvironmental elements i.e. connective tissue cells and proteins. This study seeks to investigate specific keratinocyte-microenvironment interactions which will ultimately be used to improve current methods for generating skin tissue for burns patien ....The stem cells in the outer protective layers of the epithelium of the skin (keratinocyte stem cells), possess an intrinsically high capability to regenerate tissue.

The Role Of Osteocytes In Particle Induced Osteolysis

Funding Amount
$457,196.00
Summary
Hip replacements often fail due to the loss of adjacent bone. Metal or polyethylene particles are produced as the prosthesis bearing surface wears but how do these particles lead to bone loss? Our work suggests involvement of osteocytes within the bone mineral, which are increasingly understood to drive bone physiology and pathology. We will explore the role of the osteocytes by examining their response to particles, which may identify a new target to prevent particle-induced bone loss.
Enhancing Joint Replacement Outcomes Through National Data Linkage

Funding Amount
$776,063.00
Summary
This is an Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) project that involves linking Registry data with state and federal government health datasets. This will help to better understand the complications and factors affecting the rate of complication after hip, knee and shoulder joint replacement. This information will be used to improve outcomes for patients having this surgery.
