Abstract: Bioelectrodes, methods of making bioelectrodes and methods of using bioelectrodes are provided. The bioelectrodes have an electrically-conductive substrate coated with an electroconductive polymer. The bioelectrode exhibits ohmic behavior over a range of about 1 Hz to about 100 KHz, where ohmic behavior means that the value of the impedance is independent of the signal frequency over the range of interest. The bioelectrode can transmit or receive an electrical signal between the electrically conductive substrate and the biological component through the conductive polymer.

Abstract: Provided are methods of detecting the presence or amount of organified radioiodine, such as radioactive thyroxine, in a sample using mass spectrometry. For example, one aspect of the invention relates to a rapid and sensitive liquid chromatography/tandem mass spectrometry (LC/MS/MS) method for the simultaneous measurement of radioactive thyroxine and non-radioactive thyroxine in human serum/plasma.
Abstract: Methods for detecting exposure to ionizing radiation are provided. In particular, methods for detecting and measuring the exposure of keratin-rich materials to ionizing radiation using optically stimulated luminescence are provided.
Abstract: Methods and systems are provided for a proactive approach for computer forensic investigations. The invention allows organizations anticipating the need for forensic analysis to prepare in advance. Digital representations are generated proactively for a specified target. A digital representation is a digest of the content of the target. Digital representations of a collection of targets indexed and organized in a data structure, such as an inverted index. The searching and comparison of digital representations of a collection of targets allows quick and accurate identification of targets having identical or similar content. Computational and storage costs are expended in advance, which allows more efficient computer forensic investigations. The present invention can be applied to numerous applications, such as computer forensic evidence gathering, misuse detection, network intrusion detection, and unauthorized network traffic detection and prevention.

Abstract: Provided are methods of detecting the presence or amount of a dihydroxyvitamin D metabolite in a sample using mass spectrometry. The methods generally comprise associating an amine with a dihydroxyvitamin D metabolite in a sample, ionizing the adduct, and detecting the amount of the ion to determine the presence or amount of the vitamin D metabolite in the sample.
Abstract: A method for killing malignant brain tumor cells in vivo entails providing replication competent herpes simplex virus vectors to tumor cells. A replication competent herpes simplex virus vector, with defective expression of the ?34.5 gene and the ribonucleotide reductase gene, specifically destroys tumor cells, is hypersensitive to anti-viral agents, and yet is not neurovirulent.
