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 about a third of patients whoâve had angioplasty without a stent, the artery that was opened begins to become narrowed again within months of the procedure. This renarrowing is called restenosis. A stent is a tiny wire mesh tube. It props open an artery and is left there permanently.
