To assess the chemical composition of electronic cigarette liquids (e-liquids) sold in Australia, in both their fresh and aged forms. Design, setting: Gas chromatography–mass spectrometry analysis of commercial e-liquids sold in Australia (online and physical stores).

In this study we assessed the effects of antigen exposure in mice pre‐sensitized with allergen following viral infection on changes in lung function, cellular responses and tight junction expression.

High risk for virus-induced asthma exacerbations in children is associated with an IRF7lo immunophenotype, but the underlying mechanisms are unclear. Here, we applied a Systems Biology approach to an animal model comprising rat strains manifesting high versus low susceptibility to experimental asthma, induced by virus/allergen coexposure, to elucidate the mechanism(s)-of-action of the high-risk asthma immunophenotype.

Intrauterine growth restriction (IUGR) is associated with asthma. Murine models of IUGR have altered airway responsiveness in the absence of any inflammatory exposure. Given that a primary feature of asthma is airway inflammation, IUGR-affected individuals may develop more substantial respiratory impairment if subsequently exposed to an allergen. This study used a maternal hypoxia-induced mouse model of IUGR to determine the combined effects of IUGR and allergy on airway responsiveness.

Climate change models predict that atmospheric carbon dioxide [CO2] levels will be between 700 and 900 ppm within the next 80yrs. In this study we aimed to assess the respiratory structure and function effects of long-term exposure to 890ppm CO2 from preconception to adulthood using a mouse model.

Findings provide further proof of concept that pharmacological targeting of airway smooth muscle thickness will be beneficial and may be facilitated by azithromycin

Electronic cigarettes (e-cigarettes) are often perceived to be a less harmful alternative to tobacco cigarettes. Potentially due to this perception, they are used by people with pre-existing respiratory conditions, such as asthma, who otherwise would not smoke. Despite this, there are few studies exploring the health effects of e-cigarette use on pre-existing asthma.

Adverse prenatal conditions can induce intrauterine growth restriction and increase the risk of adulthood metabolic disease. Mechanisms underlying developmentally programmed metabolic disease remain unclear but may involve disrupted postnatal circadian rhythms and kisspeptin signalling. 

There is no clear clinical guidance on the use of alcohol pharmacotherapies in pregnancy due to insufficient safety information. Contraception should therefore be considered for reproductive-aged females receiving alcohol pharmacotherapies not wishing to become pregnant. This study evaluated the concurrent use of alcohol pharmacotherapies with prescription contraception and other medications in Australian females of reproductive age compared to those not receiving an alcohol pharmacotherapy.

Electronic cigarettes ("e-cigarettes") are often marketed as smoking cessation tools and are used by smokers to reduce/quit cigarette smoking. The objective of this study was to assess the health effects of switching to e-cigarettes after long-term smoking in a mouse model and compare these effects with continued smoking, or quitting entirely.
