Purpose
Chronic obstructive pulmonary disease (COPD) is characterized by decreasing exercise capacity and deteriorating quality of life (QoL). Recent evidence indicates that combining exercise with manual therapy (MT) delivers greater improvements in exercise capacity than exercise alone in moderate COPD. The aim of this study was to investigate wh...
Chronic obstructive pulmonary disease (COPD) is responsible for an increasing number of deaths worldwide. Smoking is the most reliable predictor for developing COPD later in life. However, women make up the majority of patients with COPD who have never smoked. There is therefore a need to identify other factors that can predict COPD in women. The a...

Urinary tract infections (UTIs) are known to alter the normal urine composition which, in principle, can lead to changes in urine autofluorescence. This paper describes the study of human urine (normal and UTI) by using UV fluorescence excitation/emission matrices and synchronous spectra and proposes a method of diagnosing UTI without any sample pr...
Despite biological variability the spectral characteristics of undiluted human urine show relatively low autofluorescence at short UV (250-300nm) excitation. However with dilution the fluorescence intensity remarkably increases. This paper examines the mechanisms behind this effect, by using excitation-emission matrices. Corrections for the inner f...
A number of predisposing factors are recognised as increasing the risk of developing chronic pulmonary obstructive disease (COPD). There is increasing recognition that COPD may be an inflammatory disease with systemic consequences. However, the trigger for the transition from 'at risk' (stage 0) to COPD state remains unclear. The current approach t...
