The key projects undertaken at Wal-yan Respiratory Research Centre.

Western Australia Paediatric Bronchiectasis Cohort

Bronchiectasis is a chronic lung disease that impairs quality of life and reduces life expectancy.

Preferred health outcome states following treatment for pulmonary exacerbations of cystic fibrosis

Treatment for pulmonary exacerbations of cystic fibrosis (CF) can produce a range of positive and negative outcomes. Understanding which of these outcomes are achievable and desirable to people affected by disease is critical to agreeing to goals of therapy and determining endpoints for trials.

Exacerbation of chronic cigarette-smoke induced lung disease by rhinovirus in mice

A significant proportion of chronic obstructive pulmonary disease exacerbations are strongly associated with rhinovirus infection (HRV). In this study, we combined long-term cigarette smoke exposure with HRV infection in a mouse model.

In Vitro primary human airway epithelial whole exhaust exposure

The method outlined in this article is a customization of the whole exhaust exposure method generated by Mullins et al. (2016) using reprogrammed primary human airway epithelial cells as described by Martinovich et al. (2017). It has been used successfully to generate recently published data (Landwehr et al. 2021). The goal was to generate an exhaust exposure model where exhaust is collected from a modern engine, real-world exhaust concentrations are used and relevant tissues exposed to assess the effects of multiple biodiesel exposures.

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.

Limited impact of neonatal or early infant schedules of 7-valent pneumococcal conjugate vaccination

Early 7vPCV schedules have limited impact on pneumococcal vaccine type carriage in PNG

Cognition & Neurodevelopment

A child's brain undergoes massive change in the first few years of life, forming millions of new neural connections. They must quickly learn how to function in the world.

Free testosterone levels in umbilical cord blood predict infant head circumference in girls

Fetal androgens influence fetal growth as well as postnatal neurocognitive ability.
