Dissolved organic carbon (DOC) concentrations in 22 UK upland waters have increased by an average of 91% during the last 15 years. Increases have also occurred elsewhere in the UK, northern Europe and North America. A range of potential drivers of these trends are considered, including temperature, rainfall, acid deposition, land-use, nitrogen and CO2(More)
Several hypotheses have been proposed to explain recent, widespread increases in concentrations of dissolved organic carbon (DOC) in the surface waters of glaciated landscapes across eastern North America and northern and central Europe. Some invoke anthropogenic forcing through mechanisms related to climate change, nitrogen deposition or changes in land(More)
To complement the evidence-based practice paradigm, the authors argued for a core outcome measure to provide practice-based evidence for the psychological therapies. Utility requires instruments that are acceptable scientifically, as well as to service users, and a coordinated implementation of the measure at a national level. The development of the(More)
BACKGROUND An acceptable, standardised outcome measure to assess efficacy and effectiveness is needed across multiple disciplines offering psychological therapies. AIMS To present psychometric data on reliability, validity and sensitivity to change for the CORE-OM (Clinical Outcomes in Routine Evaluation--Outcome Measure). METHOD A 34-item self-report(More)
Bone marrow mesenchymal stem cells (BM-MSCs) and adipose-derived progenitor cells (ADPCs) are potential alternatives to autologous chondrocytes for cartilage resurfacing strategies. In this study, the chondrogenic potentials of these cell types were compared by quantifying neo-tissue synthesis and assaying gene expression and accumulation of extracellular(More)
Eight lake sites in central and south-west Scotland, north-west England and north Wales, forming part of the UK Acid Waters Monitoring Network (UKAWMN), have been studied with regard to the influence of marine ions on surface water chemistry. Since monitoring began in 1988 these sites have exhibited large and long-term variation in Cl concentration, which(More)
BACKGROUND Many women may suffer psychological symptoms after stillbirth and in the subsequent pregnancy. Stillbirth has not been demonstrated previously to be a stressor for post-traumatic stress disorder (PTSD). AIMS To assess incidence, correlates and predictors of PTSD during and after the pregnancy following stillbirth. METHOD A cohort study of(More)
We report a novel technology for the rapid healing of large osseous and chondral defects, based upon the genetic modification of autologous skeletal muscle and fat grafts. These tissues were selected because they not only possess mesenchymal progenitor cells and scaffolding properties, but also can be biopsied, genetically modified and returned to the(More)
