Regenerating heart valves
The human heart beats approximately 35 million times every year, pumping blood into the circulation via four different heart valves. In more than four million people each year, heart valves fail for different reasons, including birth defects, age-related deteriorations and infections. At present, clinicians use either artificial prostheses or fixed animal and cadaver-sourced tissue to...
Elite athletes possess extraordinary physical abilities enabling them to reach peak performances and recover quickly. The question is, can we extract information from their biology and use it to boost the performance level and speed up recovery of every-day-athletes? Research in different laboratories over the past years has discovered potential connections between the composition of...
Over 15 million Americans are at risk of anaphylaxis, a severe allergic reaction triggered by exposure to certain foods, materials, medications and insect bites. Every three minutes a food reaction sends someone to the emergency room. In most individuals, anaphylactic shock can be prevented by administering the counteracting drug, epinephrine. Yet, despite effective treatments, death from...
Soft exosuits offer a new way to assist the elderly in maintaining or restoring their gait, in rehabilitating children and adults with movement disorders due to Stroke, Multiple Sclerosis and Parkinson’s Disease, or to ease the physical burden of soldiers, firefighters, paramedics, farmers and others whose jobs require them to carry extremely heavy loads.For decades...
Improving Balance and Gait Control
Balance in humans relies on complex feedback from the senses that govern the body’s mechanical stability. Wyss Institute and Boston University researchers have discovered that random vibrations, too gentle to be felt, can improve the sensory feedback system and may restore stability through a mechanism known as “stochastic resonance”. By incorporating vibrating elements in insoles...
Preventing Infant Apnea
Clinicians and engineers at the Wyss Institute and the University of Massachusetts Medical School have developed a unique and proprietary system that reduces the onset of neonatal apnea in low birth-weight infants in a clinical trial at Beth Israel Deaconess Medical Center. The system makes use of the concept of Stochastic Resonance to reset the...
