We studied selected tissues from ewes and their lambs that were grazing pastures fertilized with either sewage sludge (treated) or inorganic fertilizer (control) and determined concentrations of alkylphenols and phthalates in these tissues. Mean tissue concentrations of alkylphenols were relatively low (< 10-400 microg/kg) in all animals and tissues.(More)
Soil concentrations of dioctyl phthalate (DOP) and the alkyl phenols, octyl phenol (OP) and nonyl phenol (NP), after repeated surface applications of sewage sludge to pastures, were investigated. Liquid sludge was applied at a rate of 2.25 tonnes dry matter (DM) per hectare to each of three treated (T) plots on three occasions during the summer and two(More)
OBJECTIVES To analyse the experiences of participants with Parkinson's disease (PD), who participated in an 8-week mindfulness-based cognitive therapy (MBCT) course. DESIGN AND METHOD Interpretative phenomenological analysis guided the design and method used in this study. A total of twelve participants (seven men and five women) with PD were recruited(More)
OBJECTIVES The study aimed (1) to investigate changes in older adults' emotional wellbeing (specifically depression, anxiety and stress levels) and mindful ability following a mindfulness-based cognitive therapy (MBCT) course; (2) to explore correlations between mindfulness (measured as an overall ability and as individual components; observe, describe, act(More)
There is growing interest in the development of methods capable of non-invasive characterization of stem cells prior to their use in cell-based therapies. Raman spectroscopy has previously been used to detect biochemical changes commensurate with the osteogenic, cardiogenic, and neurogenic differentiation of stem cells. The aim of this study was to(More)
There is an unmet need for the non-invasive characterisation of stem cells to facilitate the translation of cell-based therapies. Raman spectroscopy has proven utility in stem cell characterisation but as yet no method has been reported capable of taking repeated Raman measurements of living cells aseptically over time. The aim of this study was to(More)
Ectomycorrhizal fungi (EcMF) typically colonize nursery seedlings, but nutritional and growth effects of these communities are only partly understood. To examine these effects, Picea glauca seedlings collected from a tree nursery naturally colonized by three dominant EcMF were divided between fertilized and unfertilized treatments. After one growing season(More)
