BACKGROUND Testing for human papillomavirus (HPV) DNA is reportedly more sensitive than cytology for the detection of high-grade cervical intraepithelial neoplasia (CIN). The effectiveness of HPV testing in primary cervical screening was assessed in the ARTISTIC trial, which was done over two screening rounds approximately 3 years apart (2001-03 and(More)
BACKGROUND Planning for the treatment of infection with the 2009 pandemic influenza A (H1N1) virus through health care systems in developed countries during winter in the Northern Hemisphere is hampered by a lack of information from similar health care systems. METHODS We conducted an inception-cohort study in all Australian and New Zealand intensive care(More)
Plastic production pellets sampled from four beaches along a stretch of coastline (south Devon, SW England) and accompanying, loosely adhered and entrapped material removed ultrasonically have been analysed for major metals (Al, Fe, Mn) and trace metals (Cu, Zn, Pb, Ag, Cd, Co, Cr, Mo, Sb, Sn, U) following acid digestion. In most cases, metal concentrations(More)
BACKGROUND The 9q subtelomeric deletion syndrome (9qSTDS) is clinically characterised by moderate to severe mental retardation, childhood hypotonia and facial dysmorphisms. In addition, congenital heart defects, urogenital defects, epilepsy and behavioural problems are frequently observed. The syndrome can be either caused by a submicroscopic 9q34.3(More)
The distribution, abundance and chemical characteristics of plastic production pellets on beaches of the island of Malta have been determined. Pellets were observed at all locations visited and were generally most abundant (> 1000m⁻² at the surface) on the backshores of beaches with a westerly aspect. Most pellets were disc-shaped or flattened cylinders and(More)
The reliable detection of nanoparticles (NPs) in fish tissue is required to support ecotoxicological research and food safety investigations. Therefore the current work aimed to develop a simple method to determine Ti from TiO2 NPs in fish tissue whilst simultaneously measuring other elements in the sample. Spike recovery tests showed no differences when(More)
Antifouling paint particles (APP) are generated during the maintenance of boats and are shed from abandoned structures and grounded ships. Although they afford a highly visible, colourful reflection of contamination in the vicinity of the source, little systematic study has been undertaken regarding the distribution, composition and effects of APP in the(More)
Fragments of flaking paint have been sampled from eighteen boats (including sailing barges, houseboats, a trawler and a ferry) abandoned on the intertidal mudflats of two estuaries in eastern England and analysed for Cu, Pb and Zn by X-ray fluorescence (XRF) spectrometry. Median concentrations of Pb on each boat ranged from about 350 to 35,000 μg g(-1),(More)
Paint flaking off abandoned vessels or generated during boat repair is hazardous to human health and wildlife. In this study, a means of screening paint fragments using a field portable-X-ray fluorescence (FP-XRF) spectrometer is described. The technique is capable of delivering rapid, surficial measurements of Ba, Cu, Pb and Zn down to concentrations less(More)
