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.

Exposomes and metabolic health through a physical activity lens: a narrative review

In this narrative review, we provide an overview of the role of physical activity as part of differing exposomes (our combined non-genetic exposures from conception onwards) and environmental influences on metabolic health. We discuss 'beneficial' exposomes (green/natural outdoor spaces, sun exposure, healthy diets and features of built environments) that could synergise with physical activity to prevent metabolic dysfunction, particularly that related to lifestyle diseases of obesity, type 2 diabetes and metabolic syndrome.

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...

Respiratory toxicology of e-cigarettes: effect of vapours on lung function and inflammation

Electronic cigarettes (ECs) have been rapidly gaining ground on conventional cigarettes due to their efficiency in ceasing or reducing tobacco consumption,...

Influence of gestational age on dead space and alveolar ventilation in preterm infants ventilated with volume guarantee

Persistent and compartmentalised disruption of dendritic cell subpopulations in the lung following influenza A virus infection

Immunological homeostasis in the respiratory tract is thought to require balanced interactions between networks of dendritic cell (DC) subsets in lung...

Confounding effects of gavage in mice: Impaired respiratory structure and function

It is therefore clear that gavage can have significant impacts on experimental animals in terms of their stress response and overall morbidity and mortality

Mechanical Abnormalities of the Airway Wall in Adult Mice After Intrauterine Growth Restriction

We propose that mechanical abnormalities of the airway wall acquired through disrupted fetal growth impact susceptibility to disease
