The medication self-management work system of patients and informal carers from a human factors & ergonomics perspective: A scoping review protocol.

Healthcare is increasingly delivered closer to the patients' homes, which increases the level of responsibility that patients and informal carers take for managing their medication-taking, although this is associated with hazards. Medication self-management has been conceptualised as work taking place in non-formal settings ( , households), which are complex systems. Human factors and ergonomics (HFE) models provide a framework for studying such systems.

A simple H NMR based assay of total capsaicinoid levels in Capsicum using signal suppression in non-deuterated solvent.

Background: The heat of Capsicum fruits is routinely assayed using high-performance liquid chromatography (HPLC) to determine capsaicin (CA) and dihydrocapsaicin (DHC) levels. The assay can be time consuming, with each HPLC run typically lasting 10 min. Nuclear magnetic resonance (NMR) is eminently suitable for quantification of fruit extracts, although it has been largely ignored for quantitative chilli analysis.
