The New South Wales (NSW) Tissue Resource Centre (TRC) has been set up to provide Australian and international researchers with fixed and frozen brain tissue from cases that are well characterised, both clinically and pathologically, for projects related to neuropsychiatric and alcohol-related disorders. A daily review of the Department of Forensic Medicine(More)
Nitric oxide (NO*) is a multifunctional messenger molecule generated by a family of enzymes called the nitric oxide synthases (NOSs). Although NOSs have been identified in skeletal muscle, specifically brain NOS (bNOS) and endothelial NOS (eNOS), their role has not been well clarified. The goals of this investigation were to (1) characterize the(More)
Ataxia-telangiectasia (A-T) is characterised by hypersensitivity to ionising radiation (IR), immunodeficiency, neurodegeneration and predisposition to malignancy. Mutations in the A-T gene (ATM) often result in reduced levels of ATM protein and/or compromise ATM function. IR induced DNA damage is known to rapidly upregulate ATM kinase(More)
A prorenin-angiotensin system (RAS) could, via the (pro)renin receptor (ATP6AP2), have various effects in human intrauterine tissues, either directly by prorenin/ATP6AP2 cell signaling, or indirectly via angiotensin II and/or angiotensin 1-7. Here we describe RAS components in fetal membranes, decidua and placenta collected at elective cesarean section(More)
OBJECTIVE The anastomosis of peripheral nerves is a demanding procedure that has potential complications due to foreign body reactions elicited by sutures. In this study, the sutureless in vivo anastomosis of rat tibial nerves was successfully performed, using for the first time a chitosan-based laser-activated adhesive. The nerve thermal damage caused by(More)
CXCR3 and its ligands are important for the trafficking of activated CD4(+) T(H)1 T cells, CD8(+) T cells, and natural killer cells during inflammation. Recent functional studies demonstrate a more diverse role of CXCR3 in inflammatory diseases of the central nervous system (CNS). We examined the impact of CXCR3 on a less complex interferon-γ-dependent,(More)
AIMS The nm23 gene has been shown to have metastasis suppressing activity and abnormalities of the gene or its expression may be important in tumour progression and dissemination. This study was set out to investigate the possible role of the nm23 in colorectal adenocarcinoma dissemination by examining the level of nm23 protein expression in colorectal(More)
AIMS To determine the variation in p53 protein expression in phyllodes tumours and fibroadenomas of the breast. METHODS AND RESULTS Fifteen phyllodes tumours (six malignant, nine benign) and 20 fibroadenomas were examined for p53 expression by immunohistochemistry. Five of the six malignant phyllodes tumours showed moderate or strong p53 positivity at(More)
Multiple sclerosis (MS) is a chronic neurological disease of the central nervous system (CNS) characterized by demyelination associated with progressive disability. The mechanisms underlying the pathogenesis of MS remain a mystery. The highly pleiotropic syndrome known as ataxia telangiectasia (A-T) overlaps with MS in that it also presents with(More)
AIMS To investigate the effects of conditioned media from mesenchymal stem cells (MSC) on the wound healing activities of corneal stromal fibroblasts. METHODS Cell cycle analysis and early stage activation of apoptosis, chemotactic chambers and fibroblast-populated type I collagen gels were used to assess corneal stromal fibroblast proliferation,(More)
