A kinetic trap is the metastable species that is transiently or constantly produced during the reaction by trapping in a deep energy well. In most cases, the reactivity of kinetically trapped species is relatively low under the reaction conditions. Herein, we report another type of kinetically trapped species that is an incomplete cage (IC) intermediate produced during the self-assembly of a Pd L cage from ditopic ligand (L) and Pd ions with a certain lifetime, although IC has a high enough reactivity to be converted into the cage with the reaction of free L, which was confirmed by the reaction of the isolated IC and L under the self-assembly conditions. IC was kinetically trapped not because IC lies on the bottom of a deep energy well but because the conversion of the intermediates essential for the conversion of IC to the cage preferentially takes place; IC was kinetically trapped independently of the shape of the energy landscape of the self-assembly.

“…The latter represents an upgraded version of the former. Both are lightweight, triaxial accelerometer devices which have shown to be valid in COPD [17,18] and the results are interchangeable. Patients had the device attached to the frontal part of their right thigh and were instructed to keep it for at least 7 days.…”

A more profound investigation about the responses in activity levels following pulmonary rehabilitation (PR) in patients with COPD is needed. We aimed to describe groups of patients with COPD according to patterns of change in physical activity and sedentary behaviour following PR. 90 patients with COPD (60% male; mean age 67 ± 8; median FEV 47 (32-62) %pred) completed a comprehensive PR programme. A triaxial accelerometer was used to assess the time in sedentary behaviour, light activities and moderate-to-vigorous physical activity (MVPA). Additionally, exercise capacity, quality of life, and symptoms of anxiety and depression were assessed before and after PR. Six groups with different patterns of change in physical activity and sedentary behaviour were identified. The two most prevalent patterns were represented by good responders (increase in physical activity and reduction in sedentary behaviour, 34%) and poor responders (decrease in physical activity and increase in sedentary behaviour, 30%). Good responders had greater improvements in six-minute walk distance (6MWD) and symptoms of depression than poor responders (P < 0.05 for all). Strong correlation was found between changes in sedentary behaviour and changes in light activities (r = -0.89; P < 0.0001). Changes in 6MWD correlated fairly with changes in sedentary behaviour (r = -0.26), light activities (r = 0.25), and MVPA (r = 0.24); P < 0.05 for all. Different patterns of change in activity levels following PR can be found in patients with COPD. Focusing on light physical activities might be a potential strategy to make patients less sedentary, but for this to be achieved prior (or at least parallel) improvements in functional capacity seem to be necessary.

“…These outcomes were assessed during free-living conditions with the MOX Activity Monitor (Maastricht Instruments BV), a triaxial accelerometer validated in patients with COPD and in healthy subjects. 21,22 Patients and their loved ones wore their own monitors concomitantly, and the accelerometer data of each patient/loved one dyad were synchronized. Participants had the device attached to the front of the right thigh and were instructed to keep it there for at least 7 days.…”
