The respiratory health effects of acute in vivo diesel and biodiesel exhaust in a mouse modelBiodiesel, a renewable diesel fuel that can be created from almost any natural fat or oil, is promoted as a greener and healthier alternative to commercial mineral diesel without the supporting experimental data to back these claims. The aim of this research was to assess the health effects of acute exposure to two types of biodiesel exhaust, or mineral diesel exhaust or air as a control in mice.

Early moderate prenatal alcohol exposure and maternal diet impact offspring DNA methylation across speciesAlcohol consumption in pregnancy can affect genome regulation in the developing offspring but results have been contradictory. We employed a physiologically relevant murine model of short-term moderate prenatal alcohol exposure resembling common patterns of alcohol consumption in pregnancy in humans.

Effects of human rhinovirus on epithelial barrier integrity and function in children with asthmaThis study demonstrates novel intrinsic differences in tight junctions gene and protein expression between airway epithelial cells of children with and without asthma

Visualisation of Multiple Tight Junctional Complexes in Human Airway Epithelial CellsApically located tight junctions in airway epithelium perform a fundamental role in controlling macromolecule migration through paracellular spaces.

Exposomes and metabolic health through a physical activity lens: a narrative reviewIn 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.

Genome Sequence of a Lytic Staphylococcus aureus Bacteriophage Isolated from Breast MilkWe identified a double-stranded DNA (dsDNA) bacteriophage appearing to belong to Herelleviridae, genus Kayvirus. The bacteriophage, Biyabeda-mokiny 1, was isolated from breast milk using a clinical isolate of Staphylococcus aureus.

Intrauterine Growth Restriction Promotes Postnatal Airway Hyperresponsiveness Independent of Allergic DiseaseIntrauterine 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.

Soy Biodiesel Exhaust is More Toxic than Mineral Diesel Exhaust in Primary Human Airway Epithelial CellsExposure to biodiesel exhaust resulted in significantly greater cell death and a greater release of immune mediators compared to both air controls and ULSD exhaust
