Lateral Ankle sprain (LAS) is a common sports injury associated with recurrent ankle sprain, chronic ankle instability(CAI) and post-traumatic ankle osteoarthritis (PTOA). Platelet Rich Plasma (PRP) has been increasingly used forherapeutic applications in sports-related injuries, and is thought to stimulate tissue healing. We reported a case ofLAS with complete tear of anterior talofibular liga...

In this work, an alternative scenario for the substorm onset process is proposed, based on ideal ballooning stability analysis of the near-Earth plasma sheet during the March 23, 2007 THEMIS substorm event. In this scenario, the ballooning instability is initiated by the magnetic reconnection in the near-Earth plasma sheet, which in turn directly contributes to the trigger of a full onset. Usin...
