This was the beginning of modern confirmation that we are not alone in the universe. The story involves the recovery of bodies, secrecy, and death threats. Dozens of witnesses have sworn and testified to what they saw.
Numerous experimental observations suggest that local factors play a major role in the pathophysiology of restenosis. Angioplasty is invariably associated with arterial injury that provides a potent stimulus for both platelet adhesion and platelet aggregation.umerous experimental observations suggest that local factors play a major role in the pathophysiology of restenosis.

1 Enhanced Healing Factors: Vascular endothelial growth factor (VEGF) promotes healing of the vasculature. 2  In the context of stents, this would heal the implantation site and reduce platelet sequestration due to injury related chemotaxis. 3  Nitrous oxide donor compounds may also replicate this effect.rug types used in drug eluting stents. The drugs that may be useful in preventing in-stent restenosis (ISR) fall into four major categories; anti-neoplastics, immunosupressives, migration inhibitors, and enhanced healing factors.
