The response of terrestrial vegetation to a globally changing environment is central to predictions of future levels of atmospheric carbon dioxide. The role of tropical forests is critical because they are carbon-dense and highly productive. Inventory plots across Amazonia show that old-growth forests have increased in carbon storage over recent decades,(More)
An unusual microscopic abnormality has been identified in the lobectomy specimens removed surgically from the brains of 10 epileptic patients. The abnormality could seldom be identified by palpation or with the naked eye. Histologically, it consisted of congregations of large, bizarre neurones which were littered through all but the first cortical layer. In(More)
We report above-ground biomass (AGB), basal area, stem density and wood mass density estimates from 260 sample plots (mean size: 1.2 ha) in intact closed-canopy tropical forests across 12 African countries. Mean AGB is 395.7 Mg dry mass ha⁻¹ (95% CI: 14.3), substantially higher than Amazonian values, with the Congo Basin and contiguous forest region(More)
OBJECTIVE In previous reports of transoral robotic surgery (TORS) for the treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS), patients underwent routine tracheotomy. We aim to assess the feasibility of performing robotically assisted partial glossectomy without tracheotomy and to assess efficacy by comparing OSAHS outcomes with those of(More)
The National Institute for Health and Clinical Excellence (NICE) has been asked by the Department of Health to develop guidance on 'the most appropriate means of generic and specific intervention to support attitude and behaviour change at population and community levels'. This review, undertaken by The School of Pharmacy, University of London, was, with(More)
Medication errors are an important cause of patient morbidity and mortality, of which there have been few reports in psychiatry, especially in the UK. Our aim was to examine the nature, frequency and potential severity of prescribing errors in UK mental health units in a prospective, 1 week survey of errors detected by pharmacy staff in nine NHS trusts.(More)
The aura experience of 88 patients with temporal lobe epilepsy was recorded, classified and analysed. Despite the great richness of the 215 experiences described, correlations with left or right brain, nature of lesion, age of onset, etc. were only apparent when a classification into three aura groups was used. "Simple primitive" auras as sole auras were(More)
Increasing use of metallic nanomaterials is likely to result in release of these particles into aqueous environments; however, it is unclear if these materials present a hazard to aquatic organisms. Because some dissolution of metal particles will occur, it is important to distinguish effects of nanoparticulates from dissolved metals. To address this issue,(More)
