“The response of eukaryotic cells to ionising radiation (IR)-induced double-strand DNA breaks is highly conserved and involves a DNA repair mechanism characterised by the early phosphorylation of histone protein H2AX (producing the active form H2AX). Although

the expression of an induced H2AX variant has been detected in Drosophila melanogaster, the expression and radiation response of a H2AX homologue has not been reported in economically important fruit flies. We use Bactrocera tryoni (Diptera: Tephritidae, Queensland fruit fly or Q-fly) to investigate this ACY-738 price response with a view to developing molecular assays to detect/quantify exposure of fruit flies to IR and consequent DNA damage. Deep sequencing confirmed the presence of a H2AX homologue that we have termed H2AvB (i.e. variant Bactrocera) and has an identical sequence to a histone reported from the human disease vector Glossina morsitans. A

linear doseresponse of H2AvB (0400 Gy IR) was observed in whole Q-fly pupal lysates 24h post-IR and was detected at doses as low as 20 Gy. H2AvB signal peaked at similar to 20min after IR exposure and at 24h post-IR the signal remained elevated but declined significantly by 5 days. Persistent and dose-dependent H2AvB signal could be detected and quantified either by western blot or by laser scanning cytometry up to 17 days post-IR exposure in histone extracts or isolated nuclei from adult Q-flies (irradiated as pupae). We conclude that IR exposure in Q-fly leads to persistent H2AvB signals (over a period

of days) that can easily learn more be detected by western blot or quantitative immunofluorescence techniques. These approaches have potential as the basis for assays for detection and quantification of prior IR exposure in pest fruit flies.”
“This short paper is a personal account of the development of techniques to enhance the bioavailability of a series of poorly soluble drugs by particle size reduction to the nanometer size range. This is a nanotechnological approach which has come of age and has had a practical impact on drug delivery. The drug is in effect the nanosystem. (C) 2009 Elsevier B.V. All rights reserved.”
