Quantitative dual-energy radiographic absorptiometry (DRA) and dual-photon absorptiometry (DPA) were compared to determine the best means of assessing bone density. Both methods were used to evaluate the lumbar spine in 107 women (aged 35-84 years [mean, 64 years]) referred for evaluation of osteoporosis risk. High correlation was documented between(More)
Human immunodeficiency virus (HIV)-specific cytotoxic T lymphocytes (CTL) mediate immunologic selection pressure by both cytolytic and noncytolytic mechanisms. Non cytolytic mechanisms include the release of beta-chemokines blocking entry of R5 HIV-1 strains. In addition, CD8(+) cells inhibit X4 virus isolates via release of as yet poorly characterized(More)
Recent reports have implicated polymorphisms in the brain derived neurotrophic factor (BDNF) gene region in the etiology of several psychiatric phenotypes, including bipolar disorder. Significant disease association has been reported for the G allele at SNP rs6265, which encodes for Valine at position 66 of BDNF (Val66Met), an apparently functional variant(More)
Purpose Understanding individual factors associated with return to work (RTW) post-injury is an important goal of compensation systems research. The aim of the present study was to determine factors associated with time to return to work following acute unintentional injuries. Methods A prospective cohort study was conducted in Victoria, Australia. The(More)
A spectrophone measures absorptivity by sensing thermal expansion in a confined sample gas. Laser source excitation provides sufficient radiation to measure precisely very weak absorptivities at laser wavelengths. This paper describes the theoretical capability, design considerations, and experimental testing of a pulsed ruby laser absorptivity spectrophone(More)
Purpose To examine the frequency, distribution and determinants of a change in recovery expectations following non-life threatening acute orthopaedic trauma to Victorian workers. It is proposed that interventions to modify recovery expectations may reduce the burden associated with injury. However, it is not known whether recovery expectations change over(More)
This communication describes the use of uncoated cellophane (regenerated cellulose films) for the fabrication of microplates, and the use of coated cellophane for the fabrication of open-channel microfluidic devices. The microplates based on uncoated cellophane are particularly interesting for applications that require high transparency in the ultraviolet(More)
Exploiting the distinct excitation and emission properties of concomitant electrochemiluminophores in conjunction with the inherent color selectivity of a conventional digital camera, we create a new strategy for multiplexed electrogenerated chemiluminescence detection, suitable for the development of low-cost, portable clinical diagnostic devices.

BACKGROUND There is limited evidence to support use of local anaesthetic (LA) wound infiltration in breast surgery. This study seeks to examine whether wound infiltration of bupivacaine (0.25%) decreases post-operative pain and analgesic use, without increasing post-operative complications. METHODS A prospective single-blind study was undertaken of 90(More)
A sensitive infrasonic method for measuring the absorption of thin films at laser wavelengths has been demonstrated. A fraction of the heat absorbed from the beam by the film passes through a thin layer of gas to the back wall of the Alphaphone, while the remaining absorbed energy heats the supporting window. The gas temperature and pressure rise is then(More)
