Biodiesel exhaust: The need for a systematic approach to health effects research

Biodiesel is a generic term for fuel that can be made from virtually any plant or animal oil via transesterification of triglycerides with an alcohol...

Australian researchers join international project to curb unhealthy lifetime trajectories

Australian researchers join global effort to better understand how events during pregnancy and childhood influence the development of disease later in life.

Respiratory Environmental Health

The Respiratory Environmental Health team conducts research in early life determinants of lung growth and development, respiratory environmental health, and mechanisms of airway dysfunction in asthma and other respiratory disease.

Sensitizing and Th2 Adjuvant Activity of Cysteine Protease Allergens

Here, we report on a model that does not use Th2-skewing adjuvants and yet achieves sensitization solely via the nasal mucosa.

Distribution, composition, and activity of airway-associated adipose tissue in the porcine lung

Patients with comorbid asthma-obesity experience greater disease severity and are less responsive to therapy. We have previously reported adipose tissue within the airway wall that positively correlated with body mass index. Accumulation of biologically active adipose tissue may result in the local release of adipokines and disrupt large and small airway function depending on its anatomical distribution. This study therefore characterized airway-associated adipose tissue distribution, lipid composition, and adipokine activity in a porcine model.

Fuel feedstock determines biodiesel exhaust toxicity in a human airway epithelial cell exposure model

Biodiesel is promoted as a sustainable replacement for commercial diesel. Biodiesel fuel and exhaust properties change depending on the base feedstock oil/fat used during creation. The aims of this study were, for the first time, to compare the exhaust exposure health impacts of a wide range of biodiesels made from different feedstocks and relate these effects with the corresponding exhaust characteristics.

Intrauterine growth restriction promotes hypothalamic circadian dysregulation in adult mouse offspring

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. 

The effects of electronic cigarette aerosol exposure on inflammation and lung function in mice

This study shows, for the first time, that exposure to e-cigarette aerosol during adolescence and early adulthood is not harmless to the lungs and can result in significant impairments in lung function.

Pulmonary microRNA profiles identify involvement of Creb1 and Sec14l3 in bronchial epithelial changes in allergic asthma

In this study, we aimed to use microRNAs-which are critical regulators of signaling cascades-to identify so far uncharacterized asthma pathogenesis pathways
