In the mature nervous system, changes in synaptic strength correlate with neuronal structure. Members of Nogo-66 receptor family have been implicated regulating morphology. 1 (NgR1) supports binding myelin inhibitors Nogo-A, MAG (myelin-associated glycoprotein), and OMgp (oligodendrocyte is important for growth cone collapse response to acutely presented vitro. After injury corticospinal tract, NgR1 limits axon collateral sprouting but not blocking long-distance regenerative vivo. Here, we...

Living in greener areas, or close to green and blue spaces (GBS; eg, parks, lakes, beaches), is associated with better mental health, but longitudinal evidence when GBS exposures precede outcomes less available. We aimed analyse the effect of living moving areas more space access on subsequent adult health over time, while explicitly considering inequalities.A cohort people Wales, UK (≥16 years; n=2 341 591) was constructed from electronic record data sources Jan 1, 2008 Oct 31, 2019,...
Abstract Background Exposure to green space can protect against poor health through a variety of mechanisms. However, there is heterogeneity in methodological approaches exposure assessments which makes creating effective policy recommendations challenging.

In Britain, sexual health clinics (SHCs) are the most common location for STI diagnosis but many people with risk behaviours do not attend. We estimate prevalence of SHC attendance and how this varies by sociodemographic behavioural factors (including unsafe sex) describe hypothetical service preferences those reporting sex.Complex survey analyses data from Britain's third National Survey Sexual Attitudes Lifestyles, a probability 15 162 aged 16-74 years, undertaken 2010-2012.Overall, recent...
Natural environments can promote well-being through multiple mechanisms. Many studies have investigated relationships between residential green/blue space (GBS) and well-being, fewer explore with actual use of GBS. We used a nationally representative survey, the National Survey for Wales, anonymously linked spatial GBS data to investigate associations both time in nature (N = 7631). Both spent were associated subjective well-being. Higher green-ness was lower counter hypotheses (predicting...
