OBJECTIVES To study the demographics, risk behaviours and morbidity of young long-term international travellers (backpackers) attending a sexual health service in Sydney, Australia. METHODS Data on new patients were extracted from the Sydney Sexual Health Centre database for the period 1998 to 2006. The sexual risk behaviours and morbidity of the(More)
The use of primary cultures of astrocytes as indicators of toxic potential was assessed using 20 selected compounds. Multiple endpoints were used to evaluate astrocyte reactions. Trypan blue dye exclusion and total cellular protein content of the cells were used as general indices. EC(50) values from the trypan blue experiments could be used to rank(More)
BACKGROUND Xenotransplantation could provide a solution to the donor shortage that is currently the major barrier to solid-organ transplantation. The ability to breed pigs with multiple genetic modifications provides a unique opportunity to explore the immunologic challenges of pulmonary xenotransplantation. METHODS Explanted lungs from wild-type and 3(More)
Fluorescence microscopy is an important and fundamental tool for biomedical research. Optical microscopy is almost non-invasive and allows highly spatially resolved images of organisms, cells, macromolecular complexes, and biomolecules to be obtained. Generally speaking, the architecture of the observed structures is not significantly modified and the(More)
BACKGROUND Residual forefoot supination is commonly encountered during a flatfoot reconstruction, and a new technique for its treatment is described. Contrary to the standard Cotton osteotomy, a plantar closing wedge osteotomy of the medial cuneiform (PCWOMC) was performed, which has a number of advantages. METHODS We followed 10 feet in 9 patients who(More)
In the absence of a formal in vitro alternative model for neurotoxicity testing, the CellTox Centre, in collaboration with the University of Salford, FRAME and the EEC, has set up an initial pre-validation trial of a three-tiered scheme that was originally proposed in 1989. Using a cell battery of neuroblastomas and primary neural cultures (Tier I) and(More)
