Local lung responses following endobronchial elastase and lipopolysaccharide instillation in sheep

, 2006
Chronic lipopolysaccharide (LPS) exposure may contribute to the pathogenesis of a number of lung diseases including COPD and emphysema. We sought to develop a large-animal model of emphysema using repeated LPS administration into sheep lung segments.

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater

The Journal of Physiology, EarlyView.
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

Changes in elastic fibres in the small airways and alveoli in COPD

, 2008
Small airways are the major site of airflow obstruction in chronic obstructive pulmonary disease (COPD). This is attributed to loss of elastin in alveoli and fibrosis in small airways.

A Novel Low‐Cost Technique for Three‐Dimensional Cardiopulmonary Preservation Using Internal Poly(Vinyl Acetate) (PVAc) Injection

Anatomia, Histologia, Embryologia, Volume 55, Issue 4, July 2026.
ABSTRACT Anatomical preservation is essential for teaching and research; however, conventional formaldehyde‐based techniques present limitations due to toxicity, volatility and environmental impact. Plastination provides excellent morphological quality, but its high cost, reliance on flammable solvents and requirement for specialized equipment limit ...

Flow‐controlled expiration improves gas exchange in anaesthetised horses undergoing orthopaedic surgery

Equine Veterinary Journal, Volume 58, Issue 4, Page 917-924, July 2026.
Abstract Background Flow‐controlled expiration (FLEX) has been shown to significantly enhance oxygenation in horses under laboratory conditions. Objective This study aims to corroborate these findings by evaluating the effects of FLEX on gas exchange in a randomised clinical trial involving a large population of clinical horses undergoing orthopaedic ...
