Air pollution modifies colonisation factors in beneficial symbiont Snodgrassella and disrupts the bumblebee gut microbiome.

Particulate air pollutants, a major air pollution component, are detrimental to human health and a significant risk to wildlife and ecosystems globally. Here we report the effects of particulate pollutant black carbon on the beneficial gut microbiome of important global insect pollinator, the buff-tailed bumblebee (Bombus terrestris). Our data shows that exposure to black carbon particulates alters biofilm structure, gene expression and initial adhesion of beneficial bee gut coloniser, Snodgrassella alvi.

Membrane-bound model of the ternary complex between factor VIIa/tissue factor and factor X.

Formation of the extrinsic complex (EC) on cell surfaces is the event that triggers the coagulation cascade. Tissue factor (TF) and factor VIIa (FVIIa) form the EC together with factor X (FX) on phosphatidylserine-containing membranes, leading to FX activation by TF:FVIIa. This lipid dependence has made experimental characterization of the EC structure challenging.

Optimisation of coumaric acid production from aromatic amino acids in Kluyveromyces marxianus.

Yeasts are attractive hosts for the production of heterologous products due to their genetic tractability and relative ease of growth. While the baker's yeast Saccharomyces cerevisiae is a powerful workhorse of the biotechnology industry, the species has metabolic limitations and it is critical that we develop alternative platforms that will facilitate the development of bioprocesses that rely on sustainable feedstocks. In this study, we used synthetic biology tools to construct coumaric acid-producing strains of Kluyveromyces marxianus, a yeast whose physiological traits render it attractive for biotechnology applications.

Preventing cardiovascular disease in at-risk patients: Results of a pilot behavioural health programme in general practice.

Background: The 'High-Risk Prevention Programme' (HRPP) involved a six-week health behaviour change programme based in general practices and aimed to address cardiovascular disease (CVD) risk in disadvantaged Irish communities.

Objectives: This pilot study aimed to establish the HRPP's likely effectiveness and acceptability to inform the development of a future definitive trial.

Methods: The HRPP was conducted at six general practices in disadvantaged areas in the Ireland East region.
