This study assessed the fitness for purpose of consumables used for the recovery of body-fluids and biological material for subsequent DNA analysis in forensic medical examinations, specifically within Sexual Assault Referral Centres (SARCs). All 55 SARCs in England and Wales participated in this validation exercise by submitting unused critical DNA consumables from their local storage areas. Overall, 261 consumable items identified as forensic DNA grade were assessed for the presence of DNA contamination and 100 % passed testing, demonstrating that consumables purchased under the National Scenes of Crimes Consumables Contract remained fit for purpose, regarding detectable levels of DNA, up to the point of use within the SARCs.

In this article, I review the evidence on the involvement of sleep and consolidation in word learning and processing during language comprehension, focusing on implications for theory. The theoretical basis for the review is a complementary systems account of word learning involving flexible (hippocampal) and stable (cortical) pathways to lexical knowledge. I argue that the accumulated data are consistent with a role for both pathways in both learning and recognition of lexical items, with sleep and consolidation supporting the transfer of recent experience between the pathways.

One way to investigate memory reactivation in sleep is by exposing the sleeping brain to auditory retrieval cues; a paradigm known as targeted memory reactivation. To what extent the acoustic properties of memory cues influence the effectiveness of targeted memory reactivation, however, has received limited attention.

However, whether holistic reinstatement occurs, and whether hippocampal pattern completion continues to drive reinstatement, after a period of consolidation is unclear. Theories of systems consolidation predict either a time-variant or time-invariant role of the hippocampus in the holistic retrieval of episodic events.
