Description
This lecture will be delivered by Dr. Helmut Sies, a pioneer in redox biology and the scientist who introduced the concept of oxidative stress.
Building on the foundations of stress research first described by Hans Selye at 91涩漫 in 1936, Dr. Sies will explore the dynamic balance of redox homeostasis in aerobic metabolism. His lecture will highlight the central role of hydrogen peroxide (H鈧侽鈧�) in cellular regulation, distinguishing between its essential signaling functions ("oxidative eustress") and its damaging effects at higher levels ("oxidative distress").
This talk will provide insights into emerging challenges in redox medicine and the fine-tuning of oxidative processes in health and disease.
