The oral microbiome and its effect on exhaled breath volatile analysis–the elephant in the room Open
The rapid transfer of volatiles from alveolar blood into the lungs and then out of the body in exhaled breath leads to the common and natural conclusion that these volatiles provide information on health and metabolic processes, with consi…

Convolutional neural network approach to ion Coulomb crystal image analysis Open
This paper reports on the use of a convolutional neural network methodology to analyze fluorescence images of calcium-ion Coulomb crystals in the gas phase. A transfer-learning approach is adopted using the publicly available RESNET50 mode…

Computed cardiopulmonography: Effects of physical characteristics on lung parameter estimates Open
Computed cardiopulmonography (CCP) is a technique that measures lung volumes (functional residual capacity and deadspace) together with novel parameters reflecting lung inhomogeneities (non‐uniformities in lung inflation and deadspace path…

Selective reagent ion – time-of-flight – mass spectrometric studies of cocaine: investigations of charge and proton transfer reaction processes Open
Investigations are reported for the reactions of H3O+.(H2O)n (n = 0 and 1), NO+ and O2+• with cocaine (C17H21NO4) using a Selective Reagent Ion-Time-of-Flight-Mass Spectrometer (SRI-ToF-MS) covering a range of DC reduced electric field val…

Effects of biologic therapy on novel indices of lung inhomogeneity in patients with severe type-2 high asthma Open
Introduction/Aim Lung inhomogeneity measures obtained using computed cardiopulmonography (CCP) are sensitive to small-airways disease. Here, we assessed changes in lung inhomogeneity in patients with type-2 high asthma treated with biologi…

S94 Computed cardiopulmonography: an innovative assessment of lung function before and after starting biologic therapy for Th-2 high asthma Open
Aim Anti IL5/anti-IL5R biologics are highly effective in asthma by targeting eosinophilic inflammation and reducing exacerbations, but their effects on lung function are less clear. The aim of the study was to explore whether a novel lung …

Accurate real-time F<sub>E</sub>NO expirograms using complementary optical sensors Open
The fraction of exhaled nitric oxide (F E NO) is an important biomarker for the diagnosis and management of asthma and other pulmonary diseases associated with airway inflammation. In this study we report on a novel method for accurate, hi…
