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.

In an attempt to further decrease restenosis in the vessel, stents containing a drug (e.g., sirolimus or paclitaxel) that is emitted over a few days to a few weeks are now being used. After implantation, the stent becomes covered with cells after two to three weeks, becoming a permanent part of the blood vessel wall.
