DOI: 10.1148/radiol.2017171519

Abstract: Purpose To identify a prevalent computed tomography (CT) subtype in patients with chronic obstructive pulmonary disease (COPD) by separating emphysematous from nonemphysematous contributions to total gas trapping and to attempt to predict and grade the… read more here.

DOI: 10.1164/rccm.201705-0855oc

Abstract: Rationale: A substantial proportion of subjects without overt airflow obstruction have significant respiratory morbidity and structural abnormalities as visualized by computed tomography. Whether regions of the lung that appear normal using traditional computed tomography criteria… read more here.

DOI: 10.1183/1393003.congress-2017.pa2210

Abstract: Background: Multiple breath nitrogen washout (MBNW) indices provide insight into ventilation heterogeneity globally (LCI) and within the acinar (Sacin) and conducting (Scond) airways. Normal ageing leads to an accelerated deterioration of Sacin and LCI in… read more here.

DOI: 10.2144/000114629

Abstract: Research into cellular metabolism has become more high-throughput, with typical cell-culture experiments being performed in multiwell plates (microplates). This format presents a challenge when trying to collect gaseous products, such as carbon dioxide (CO2), which… read more here.
