Understanding how and why users might use NHS repositories: A mixed methods study.

Background: There is little evidence on the use or potential use of NHS repositories within the UK.

Methods: A mixed methods (quantitative/qualitative) study of two repositories: amber-the home of ambulance service research, and East Midlands Evidence Repository (EMER). A structured online questionnaire was distributed via the repository home page, and promoted via social media, email networks, and lists.

Methods for Studying Motor-Driven Viral DNA Packaging in Bacteriophages phi29, Lambda, and T4 via Single DNA Molecule Manipulation and Rapid Solution Exchange.

Viral DNA packaging is a required step in the assembly of many dsDNA viruses. A molecular motor fueled by ATP hydrolysis packages the viral genome to near crystalline density inside a pre-formed prohead shell in ~5 min at room temperature in vitro. We describe procedures for measuring the packaging of single DNA molecules into single viral proheads with optical tweezers.

Pressure ulcer prevention for people with long-term neurological conditions (LTNCs) who self-manage care and live at home.

Aim: To develop a Theory of Change (ToC) pathway to facilitate the development of a multi-component intervention package supporting pressure Ulcer (PU) risk identification and management, in partnership with people with Long Term Neurological Conditions (LTNC) who self-manage care and live at home, their informal carers and PAs.

Methods: A participatory approach, with extensive input from those whose lives are the focus of the research, was used throughout the 4 interlinked work packages (WP): Iterative data analysis was undertaken with emerging findings from each WP informing subsequent stages of the study.

Findings: Overall, 74 participants contributed across the 4 WPs, incorporating 31 Service Users (SU), 8 carers, 9 Personal Assistants (PAs) and 26 professional stakeholders.

Ligand Chirality Transfer from Solution State to the Crystalline Self-Assemblies in Circularly Polarized Luminescence (CPL) Active Lanthanide Systems.

The synthesis of a family of chiral and enantiomerically pure pyridyl-diamide (pda) ligands that upon complexation with europium [Eu(CFSO)] result in chiral complexes with metal centered luminescence is reported; the sets of enantiomers giving rise to both circular dichroism (CD) and circularly polarized luminescence (CPL) signatures. The solid-state structures of these chiral metallosupramolecular systems are determined using X-ray diffraction showing that the ligand chirality is transferred from solution to the solid state. This optically favorable helical packing arrangement is confirmed by recording the CPL spectra from the crystalline assembly by using steady state and enantioselective differential chiral contrast (EDCC) CPL Laser Scanning Confocal Microscopy (CPL-LSCM) where the two enantiomers can be clearly distinguished.
