Summary
The aim of the project is to understand how some blood clotting factors may be involved with the regulation of the extracellullar matrix (the material that exists between cells) and angiogenesis (new blood vessel formation). New blood vessel growth occurs in a wide variety of situations including: healing of a flesh wound, the healing phase following a heart attack, development of the eye disease associated with sugar diabetes, in and around a cancerous growth, in the uterus during the normal me ....The aim of the project is to understand how some blood clotting factors may be involved with the regulation of the extracellullar matrix (the material that exists between cells) and angiogenesis (new blood vessel formation). New blood vessel growth occurs in a wide variety of situations including: healing of a flesh wound, the healing phase following a heart attack, development of the eye disease associated with sugar diabetes, in and around a cancerous growth, in the uterus during the normal menstrual cycle, and for the normal growth and development of the placenta and a new baby. The processes by which these new blood vessels form and the factors contributing to the maintenance of their structure are incompletely understood. However, it is known that the interaction of cells and the surrounding extracellular matrix is critical for normal cell function and in particular for new blood vessel formation. Studies in this project will seek to define a relationship between some of the factors which regulate blood clotting, and those that regulate turnover of the extracellular matrix and new blood vessel formation. In particular, how blood clotting factors may be invovled in the regulation of the extracellular matrix will be studied in a rapidly developing tissue, the mouse placenta. The role of blood clotting factors in regulation of new blood vessel formation into an artificial avascular tissue will also be examined. These studies will employ some of the new genetic techniques to understand new roles for proteins which have been traditionally thought to act in only one way. This research has the potential to provide new insights into how blood vessels are formed and are subsequently maintained. This increased understanding will provide the knowledge required for the development of new therapeutic strategies to correct the process when it goes wrong, is unwanted or underdeveloped in human disease.Read moreRead less
Factor XII Dependent Coagulation, Thrombin And Platelet Glycoprotein 1ba In Arterial Thrombosis And Bleeding Disorders

Summary
Clot formation is the key event underlying heart attacks and strokes. There is new data that Factor XII (FXII) can play an important role in clot formation-thrombosis. We aim to examine the role FXII plays in clot formation, in particular the role of FXII in thrombin generation, which is the central event of clot formation, and its interaction with platelet glycoprotein 1ba (another important molecule in thrombosis). New insights into clotting and new therapies can result from our research.
Acute Traumatic Coagulopathy- Mechanisms And Measurement

Funding Amount
$188,226.00
Summary
Acute traumatic coagulopathy (ATC) refers to impaired blood clotting post major trauma and is associated with high, early mortality. Inability to predict this disorder and poor knowledge regarding its detailed biochemical mechanism has hindered development of evidence based guidelines to manage patients with ATC. This project aims to correlate early biochemical disorders with clinical management and outcomes post trauma to determine mechanisms leading to ATC and determine management strategies.
This research is directed by a team of medical and basic scientists with expertise in mechanisms of inflammation relevant to human disease. The program will investigate the molecular and cellular events that are responsible for inflammation in the kidneys, joints and blood vessels which lead to diseases such as glomerulonephritis, arthritis and atherosclerosis. The aim of the research is to find new therapeutic targets which may be specific to certain organs or disease processes, in order to dev ....This research is directed by a team of medical and basic scientists with expertise in mechanisms of inflammation relevant to human disease. The program will investigate the molecular and cellular events that are responsible for inflammation in the kidneys, joints and blood vessels which lead to diseases such as glomerulonephritis, arthritis and atherosclerosis. The aim of the research is to find new therapeutic targets which may be specific to certain organs or disease processes, in order to develop more effective and selective treatments ofchronic inflammatory disease in humans.Read moreRead less
Safety And Quality Of Life Of Peri-operative Transdermal Estradiol Continuation During Gender Affirmation Surgery In Transgender Women: A Randomised Placebo-controlled Trial
Funder

Funding Amount
$92,335.00
Summary
Despite no clear evidence, transgender women are told to stop their feminising estrogen treatment several weeks before gender surgery, but this causes severe 'menopausal symptoms' with hot flushes, depression and distress compounding an already stressful preparation for and recovery from major surgery. This trial will establish if continuing estrogen gel around the time of surgery is safe and effective at improving 'menopausal symptoms'.
A Novel Point Of Care (PoC) Device For Predicting And Monitoring Bleeding And Clotting (haemostasis)

Funding Amount
$608,979.00
Summary
Manipulating the bleeding/clotting system is a critical but expensive part of modern medicine, eg some people need blood thinners while others can bleed too much. Thrombin generation is the ideal overall test for the bleeding/clotting of blood, but current methods have major problems. We developed and patented a test that deals with most of the problems. This proposal will create an assay that is easy for doctors to perform without a specialised laboratory.
Elimination of the transplant waiting list is the ultimate goal of research into pigto-human xenotransplantation. The prospect of success has been improved recently by refinements in technology used to introduce genetic modifications in the pig, although the genes that will need to be expressed or deleted are still undecided. What is clear is that intravascular thrombosis, a critical mediator of rejection of pig xenografts, must be overcome.

What is clear is that intravascular thrombosis, a critical mediator of rejection of pig xenografts, must be overcome. This project aims to investigate the use of anticoagulant gene expression to prevent intravascular thrombosis associated with xenograft rejection.Read moreRead less
