Carbon dioxide overload, detected in human blood, suggests a potentially toxic atmosphere within 50 years

Anthropogenic activities are increasing the amount of carbon dioxide (CO2) in the atmosphere. There is mounting experimental evidence that lifetime exposure to these increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. However, directly assessing this in humans is very difficult. 

Biodiesel Exhaust Toxicity with and without Diethylene Glycol Dimethyl Ether Fuel Additive in Primary Airway Epithelial Cells Grown at the Air-Liquid Interface

Biodiesel usage is increasing steadily worldwide as the push for renewable fuel sources increases. The increased oxygen content in biodiesel fuel is believed to cause decreased particulate matter (PM) and increased nitrous oxides within its exhaust.

The influence of moving walls on respiratory aerosol deposition modelling

This work initially examines particle deposition in a Weibull-type geometry, comparing traditional computational fluid dynamics approaches with a novel...

In utero exposure to low dose arsenic via drinking water impairs early life lung mechanics in mice

All alterations to lung mechanics following in utero arsenic exposure were recovered by adulthood.

The mechanism of deep inspiration-induced bronchoprotection: Evidence from a mouse model

In healthy individuals, deep inspirations (DIs) taken prior to a bronchial challenge reduce the bronchoconstrictor response, which is termed...

Acute diesel exhaust particle exposure increases viral titre and inflammation associated with existing influenza

Exposure to diesel exhaust particles (DEP) is thought to exacerbate many pre-existing respiratory diseases.

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.

Physiological and inflammatory responses in an anthropomorphically relevant model of acute diesel exhaust particle exposure are sex and dose-dependent

Diesel exhaust particles (DEP) are an important contributor to suspended particulate matter (PM) in urban areas. While epidemiological evidence exists for a...

Respiratory Health Effects of In Vivo Sub-Chronic Diesel and Biodiesel Exhaust Exposure

Biodiesel, which can be made from a variety of natural oils, is currently promoted as a sustainable, healthier replacement for commercial mineral diesel despite little experimental data supporting this. The aim of our research was to investigate the health impacts of exposure to exhaust generated by the combustion of diesel and two different biodiesels.

Electronic Cigarette Usage Patterns and Perceptions in Adult Australians

Despite their increasing popularity, and Australia's unique regulatory environment, how and why Australian adults use e-cigarettes and their perceptions of their safety, efficacy and regulation have not been extensively reported before. In this study, we screened 2217 adult Australians with the aim of assessing these questions in a sample of current or former e-cigarette users.
