Measurement of breathing in patients with post-COVID-19 using structured light plethysmography (SLP)

BMJ Open Respiratory Research, 2021
Introduction COVID-19 pandemic has had a huge impact on global health to date, with 5.6 million cases in the UK since its emergence. The respiratory symptoms largely mimic those of pneumonia’ with symptoms ranging from mild to severe.

Automated Estimation of Total Lung Volume using Chest Radiographs and Deep Learning [PDF]

, 2021
Total lung volume is an important quantitative biomarker and is used for the assessment of restrictive lung diseases. In this study, we investigate the performance of several deep-learning approaches for automated measurement of total lung volume from chest radiographs.

The value of high-resolution computed tomography (HRCT) to determine exercise ventilatory inefficiency and dynamic hyperinflation in adult patients with cystic fibrosis

Respiratory Research, 2019
Introduction In Cystic Fibrosis (CF), exercise ventilatory inefficiency and dynamic hyperinflation (DH) cause exercise limitation and induce poor exercise tolerance.

Cardiac mechanics and reverse remodelling under mechanical support from left ventricular assist devices

Frontiers in Cardiovascular Medicine, 2023
In recent years, development of mechanical circulatory support devices has proved to be a new treatment modality, in addition to standard pharmacological therapy, for patients with heart failure or acutely depressed cardiac function.

Concurrent micro- to macro-cardiac electrophysiology in myocyte cultures and human heart slices

Scientific Reports, 2018
The contact cardiac electrogram is derived from the extracellular manifestation of cellular action potentials and cell-to-cell communication. It is used to guide catheter based clinical procedures.

Severe acute respiratory failure due to a multifactorial diffuse alveolar haemorrhage

Respirology Case Reports, 2020
Diffuse alveolar haemorrhage (DAH) is a life‐threatening syndrome caused by infection, coagulation disorders or autoimmune diseases. We here report the case of an 81‐year‐old male subject affected by a multifactorial DAH, in which the bleeding was ...

Partial Mechanical Unloading of the Heart Disrupts L-Type Calcium Channel and Beta-Adrenoceptor Signaling Microdomains

Frontiers in Physiology, 2018
Introduction: We investigated the effect of partial mechanical unloading (PMU) of the heart on the physiology of calcium and beta-adrenoceptor-cAMP (βAR-cAMP) microdomains.

Extracting lung function-correlated information from CT-encoded static textures [PDF]

, 2022
The inherent characteristics of lung tissues, which are independent of breathing manoeuvre, may provide fundamental information on lung function. This paper attempted to study function-correlated lung textures and their spatial distribution from CT.

Regulation of Immunoproteasome Function in the Lung [PDF]

Scientific Reports, 2015
AbstractImpaired immune function contributes to the development of chronic obstructive pulmonary disease (COPD). Disease progression is further exacerbated by pathogen infections due to impaired immune responses. Elimination of infected cells is achieved by cytotoxic CD8+  T cells that are activated by MHC I-mediated presentation of pathogen-derived ...
