Ancient mitochondrial DNA connects house mice in the British Isles to trade across Europe over three millennia.

Background: The earliest records in Britain for the western European house mouse (Mus musculus domesticus) date from the Late Bronze Age. The arrival of this commensal species in Britain is thought to be related to human transport and trade with continental Europe. In order to study this arrival, we collected a total of 16 ancient mouse mandibulae from four early British archaeological sites, ranging from the Late Bronze Age to the Roman period.

Nicotine preloading for smoking cessation: the Preloading RCT.

Background: Nicotine preloading means using nicotine replacement therapy prior to a quit date while smoking normally. The aim is to reduce the drive to smoke, thereby reducing cravings for smoking after quit day, which are the main cause of early relapse. A prior systematic review showed inconclusive and heterogeneous evidence that preloading was effective and little evidence of the mechanism of action, with no cost-effectiveness data.

A randomised, double-blind controlled trial of intranasal midazolam for the palliation of dyspnoea in patients with life-limiting disease.

Purpose: Anxiety is a major component of breathlessness and is often palliated with benzodiazepines. Midazolam is a short-acting water-soluble benzodiazepine with a rapid onset of action and short half-life. Intranasal midazolam had been shown to be of marked clinical benefit in an uncontrolled pilot study for the control of dyspnoea.
