Intercellular communication between neurons and glial cells via extracellular vesicles（EVs）as a novel mechanism of information transfer has been shown to be involved in regeneration processes within the central nervous system（CNS）（Rajendran et al.,2014）.Hence,to take advantage of EV signaling for therapeutic applications appears to be a completely new approach to promote regeneration.

Currently,we know that neuronal outgrowth during development and regeneration requires a complex interaction of intra-and extracellular molecules such as growth factors,neurotransmitters and extracellular matrix proteins（O’Donnell et al.,2009）.Furthermore,the discovery of a broad spectrum of growth-promoting cues has led to novel concepts for thera-peutic strategies.

BACKGROUND Total hip and knee replacements are being performed in increasing numbers in progressively younger patients with higher activity demands. Many such patients have expectations of returning to athletic activity post-operatively yet are not always able to do so and the reasons behind this have not been extensively examined. We hypothesise that any reasons for a failure to return to athletic activity post-operatively are *** To quantify the return to athletic activity following lower limb joint arthroplasty and understand qualitative reasons for altered activity *** A single centre, single surgeon retrospective questionnaire for hip and knee arthroplasty patients under age 60 years, minimum two years post-surgery with exclusion criteria of multiple degenerative joint involvement and multiple medical co-morbidities. Outcomes were validated joint-specific(Oxford hip and knee) and lifestyle questionnaires [short form 12(SF-12) and University of California, Los Angeles(UCLA)] and an activity questionnaire assessing ability participation in athletic activity post-operatively. Statistical analysis was performed on the validated outcome data, including comparison between hip and knee replacements. Frequency tables were produced to quantify the different athletic activities participated in by *** Responses were received from 64 patients(80% response rate). There was a statistically significant improvement in Oxford hip and knee scores following surgery. SF-12 scores also improved for all patients, but no statistically significant difference was seen between joints(P = 0.88). Mean UCLA scores pre-operatively were 7.67 and at two years post-operatively were 7.69, with no statistically significant change(P = 0.91). All patients reported high satisfaction and improved ability to perform athletic activity at a higher frequency compared to pre-operatively. The most common reasons for changing activity participation were not wa

The calamitous consequences of 2017 Hurricane Maria for the Caribbean island of Dominica highlighted the acute and increasing susceptibility of the region to disasters. Despite increasing international attention to disaster risk reduction, recovery from hazard events can be especially lengthy and difficult for small island developing states. In this article, we build on existing understandings of disaster risk as a physical and social condition, showing that historical processes are fundamental to understanding how conditions of risk emerge and persist over time. We take an integrated approach to analyzing the drivers of risk accumulation, using the example of Dominica, where processes set in motion during the colonial period have shaped the location of people and assets, the degree to which they might be harmed, the societal repercussions of that harm and the prospects for recovery. We focus on the underlying economic vulnerabilities and physical exposure to hazards created by agricultural, economic, and social practices, and successive disaster responses that have constrained recovery. Uncovering these historical drivers and persistent issues, elucidates lessons for pursuing a more resilient development trajectory, including through the promotion of economic restructuring and diversification, and land reform.
