What was once mere fantasy has evolved into a biotechnological revolution. Groundbreaking research in the field of vision restoration has brought hope to those who are unable to see. While vision impairment— caused by a wide range of conditions including cataracts, degenerative diseases, and accidents—impacts quality of life, research in optoelectronics and retinal prostheses continues to progress in a quest for restoring eyesight.
Heart disease is the leading cause of death in the United States. One of the most common medical interventions performed today is the percutaneous coronary intervention (PCI), which opens clogged or damaged coronary arteries (1). Since its development in 1977, PCI has been a widely used alternative to coronary artery bypass grafting (CABG), and it relieves patients of coronary arterial blockage 90-95% of the time (2, 3).
Perhaps one of the most severe medical emergencies afflicting the world today is stroke. Strokes can result in paralysis, impaired movement, memory loss, pain, behavioral change, or even death (1).
The DUJS talked to Steven Fiering, associate professor in the departments of Microbiology and Immunology, and Genetics at Dartmouth Medical School, to gain insight into his research and the use of biotechnology in scientific investigation.
For centuries, medical researchers and doctors around the world have raced to cure cancer, and they have had some success. Their treatment methods have included surgery, radiation, chemotherapy, hormone therapy, and biological therapy (1). With these treatments, they have helped millions of people go into remission.
