A simple procedure for the voltammetric detection of antioxidative activity of plant extracts based on the protection from DNA damage at the electrode surface is reported. A disposable electrochemical DNA biosensor fabricated as a carbon-based screen-printed electrode modified by a surface layer of the calf thymus double stranded (ds) DNA was used as a working electrode in combination with a si...

October 2002 Proton Decay 1

We discuss the status of supersymmetric grand unified theories [SUSY GUTs] with regards to the observation of proton decay. In this talk we focus on SUSY GUTs in 4 dimensions. We outline the major theoretical uncertainties present in the calculation of the proton lifetime and then present our best estimate of an absolute upper bound on the predicted proton lifetime. Towards the end, we consider...

Ornithol. Sci. 1: 29–40 (2002)

In this paper, we compare the foraging ecology of five Australian robins (Petroica multicolor, P. goodenovi, Eopsaltria griseogularis, Microeca fascinans, and Melanodryas cucullata) in woodlands of Western Australia. Australian robins are insectivorous and obtain the greatest proportion of their prey by pouncing from a perch to the ground. Data were collected at three different sites in eucalyp...

Cancer Immunity 2:1 (2002) - ARTICLE

Treatment with monoclonal antibodies (mAbs) specific for CD25 (anti-CD25 mAb) has been shown to suppress growth of a variety of different tumours in mice. These studies did not however determine whether or not antiCD25 mAbs facilitate tumour rejection by depletion of regulatory T cells or by binding to tumour-specific effector cells. Using a murine model of melanoma we have found that treatment...
