Horizon scanning identifies emerging issues in a given field sufficiently early to conduct research to inform policy and practice. Our group of horizon scanners, including academics and researchers, convened to identify fifteen nascent issues that could affect the conservation of biological diversity. These include the impacts of and potential human(More)
This review describes outcomes of a 2010 horizon-scanning exercise building upon the first exercise conducted in 2009. The aim of both horizon scans was to identify emerging issues that could have substantial impacts on the conservation of biological diversity, and to do so sufficiently early to encourage policy-relevant, practical research on those issues.(More)
Long-term regular haemodialysis for chronic renal failure is associated with amyloidosis. In this condition excess amounts of the unexcretable plasma protein beta-microglobulin are laid down in tendons, joints and bones. Amyloidosis presents with various musculoskeletal disorders only after several years of dialysis. We reviewed 83 patients who had been(More)
Microbial manganese oxidation was demonstrated at high Mn concentrations (5 g/liter) in bacterial cultures in the presence of a microalga. The structure of the oxide produced varied depending on the bacterial strain and mode of culture. A nonaxenic, acid-tolerant microalga, a Chlamydomonas sp., was found to mediate formation of manganite (gamma-MnOOH).(More)
A Greek male with acute myeloid leukaemia (AML) developed a pyrexial illness while neutropenic and Trichosporon beigelii was isolated from his skin, blood and urine. This infection appeared to resolve with a rising neutrophil count, but recurred in the next episode of neutropenia. T. beigelii was isolated from an aspirate from an inflamed knee. Despite a(More)
Microorganisms and algae have potential as agents for removing inorganic pollutants from wastewaters. Metal ion uptake mechanisms function either by passive chemical adsorption or by metabolically driven processes. Ion selective uptake processes are being sought in algae to facilitate purification of valuable metal ions for recycling. Sessile macroalgae(More)
In the presence of unicellular microalgae, bacterial manganese oxidation was increased by up to ten times the rate produced by bacterial oxidation alone. Azide-poisoned controls demonstrated that the manganese-oxidizing bacteria were active in the algal-bacterial oxidation of manganese. Scanning electron microscopy showed that oxide formation occurred in a(More)
