All-optical mapping of Ca transport and homeostasis in dendrites.

Calcium mediates many important signals in dendrites. However, the basic transport properties of calcium in dendrites have been difficult to measure: how far and how fast does a local influx of calcium propagate? We developed an all-optical system for simultaneous targeted Ca import and Ca concentration mapping. We co-expressed a blue light-activated calcium selective channelrhodopsin, CapChR2, with a far-red calcium sensor, FR-GECO1c, in cultured rat hippocampal neurons, and used patterned optogenetic stimulation to introduce calcium into cells with user-defined patterns of space and time.

Diminishing neuronal acidification by channelrhodopsins with low proton conduction.

Many channelrhodopsins are permeable to protons. We found that in neurons, activation of a high-current channelrhodopsin, CheRiff, led to significant acidification, with faster acidification in the dendrites than in the soma. Experiments with patterned optogenetic stimulation in monolayers of HEK cells established that the acidification was due to proton transport through the opsin, rather than through other voltage-dependent channels.

Self-efficacy as a prognostic factor and treatment moderator in chronic musculoskeletal pain patients attending pain management programmes: A systematic review.

Objective: Evidence on the effectiveness of pain management programmes (PMPs) for chronic pain patients is mixed. Self-efficacy may be associated with outcome of PMPs. The purpose of this systematic review was to assess the role of self-efficacy as a (i) prognostic factor and (ii) moderator of treatment, in chronic musculoskeletal pain (CMP) patients attending a PMP.

A 5-year evaluation of the emergency contraception enhanced community pharmacy service provided in Wales.

Background: Access to emergency contraception (EC) has been a core component of attempts to address high teenage pregnancy rates in Wales. A national service was commissioned in 2011, allowing supply of EC free of charge from community pharmacies (CPs). This study investigated 5 years of the EC service, to describe its use and investigate changes in the pattern of use over time.

Using Evidence-Based Design to Improve Pharmacy Department Efficiency.

Using a case study of a pharmacy department rebuild in the South West of England, this article examines the use of evidence-based design to improve the efficiency and staff well-being with a new design. This article compares three designs, the current design, an anecdotal design, and an evidence-based design, to identify how evidence-based design can improve efficiency and staff well-being by reducing walking time and distance. Data were collected from the existing building and used to measure the efficiency of the department in its current state.
