Summary
Prisoner populations are characterised by poor health status including infectious diseases, injury, risk taking behaviours (eg. smoking and self-harm), mental illness, and substance abuse. Serosurveys of blood borne viruses such as hepatitis C and hepatitis B conducted in Australian and overseas prison settings have found that over one third of inmates have been exposed to these viruses with higher rates detected in injecting drug users and female inmates. Few attempts have been made to examine ....Prisoner populations are characterised by poor health status including infectious diseases, injury, risk taking behaviours (eg. smoking and self-harm), mental illness, and substance abuse. Serosurveys of blood borne viruses such as hepatitis C and hepatitis B conducted in Australian and overseas prison settings have found that over one third of inmates have been exposed to these viruses with higher rates detected in injecting drug users and female inmates. Few attempts have been made to examine the causes of mortality among prisoners following release from detention. Most interest has focused on overdoses in the period immediately following release; the aim of this study will examine all causes of death among individuals exposed to the correctional environment and compare these to death rates for NSW. Correctional centres house a largely male (94% in NSW) population with backgrounds of disadvantage in all areas, including Indigenous Australians, people of lower socio-economic status, those with a mental illness, and the intellectually disabled. There are currently over 21,000 (June 2001) prisoners detained in Australian correctional centres with approximately 39% housed in NSW. Fifteen percent of the NSW prisoners are Indigenous but comprise only 2% of the general population. The aims of this project will be to: (1) Identify all causes of death among ex-prisoners in NSW for the period 1985 to 2001; (2). Compare death rates in the study group with those in the NSW community; (3) Correlate pre-release health information contained in medical records with specific causes of death; (4) Compare causes of mortality among various sub-groups eg. injecting drug users, the mentally ill, violent offenders, and the intellectually disabled; (5) Examine causes of mortality between Indigenous and non-Indigenous inmates; and (6) use this information to develop pre-release programmes aimed at reducing excess mortality among this group.Read moreRead less
Targeting TRPV4 Activation Mechanisms To Reveal Novel Pain Therapies

Summary
Pain nerves sense painful chemical and physical stimuli, by opening protein "ion channels" which let small electric currents traverse the cell membrane. This pain signal is transmitted to the spinal cord and then the brain, where it is perceived as pain and elicits a reaction. But we don't know how the ion channels open. This project will investigate how receptors for painful substances open ion channels to cause pain. Understanding this mechanism will help us to make new drugs to treat pain.
The Role Of Phosphorylation And Signalling For Invasion Of Plasmodium Falciparum Into Human Erythrocytes.

Summary
The intracellular signals that govern Plasmodium falciparum malaria invasion of the red blood cell are poorly understood. It is likely calcium dependent phosphorylation leads to recruitment and activation of a cascade of proteins. This study combines a break-through in purification of viable P. falciparum merozoites with proteomic analysis of phosphorylation states to assess intracellular signalling. It is expected the processes identified will be unique to P. falciparum and targetable by drugs.
Examining The Intracellular Pathways Regulated By GM-CSF In Macrophages And The Role In Diseases Such Arthritis.

Summary
A protein, termed GM-CSF, has been shown to be important in inflammatory conditions, like rheumatoid arthritis. GM-CSF can modify the properties of a key white blood cell, the macrophage, causing macrophages to produce factors harmful to host tissue. Various therapies are being developed to block GM-CSF, however discovering other drugs that block the intracellular actions of GM-CSF in macrophages are needed. Therefore the molecular pathways governing these actions need to be defined.
Legionella bacteria are the major cause of Legionnaire’s Disease, a common form of acute pneumonia. Here we will study how the bacteria avoid killing in human cells by establishing an intracellular niche that is sequestered from the normal host cell defence pathways. In particular we hope to understand how the bacteria regulate a major protein modification pathway called ubiquitination.
