Converting blood cells to a stem cell state: an interview with Elias Zambidis, M.D., Ph.D.

The primitive stem cell state we created is called an “induced pluripotent stem cell” (iPSC). iPSC are a new, unique, and artificially-created type of stem cell that were first described in 2006 by a Japanese scientist named Shinya Yamanaka.

Morphological changes occur rapidly in response to cardiac injury

Cardiac injury leads to significant structural changes in the heart, including enlargement, excess formation of fibrous growth tissue, and abnormalities of the coronary vasculature. While associated factors have been targeted for therapeutic intervention, the results have been conflicting. Most studies have investigated these changes after six days of injury. However, advanced stages of remodeling have already begun by day seven following injury.

Renal artery stent revascularization reduces blood pressure in patients with severe hypertension

Patients with uncontrolled renovascular hypertension saw a significant improvement in their blood pressure with renal artery stent deployment. The multicenter HERCULES trial, evaluating the safety and effectiveness of the RX Herculink Elite Stent, found that patients with higher blood pressure levels at baseline had the most dramatic reduction in blood pressure following intervention.
