Teilchenphysik Pentaquarks - existieren sie wirklich? Für viel Wirbel sorgte vor zwei Jahren die Entdeckung eines Pentaquarks, eines bis dahin unbekannten Teilchens, das aus vier Quarks und einem Antiquark besteht. Seitdem hat es jedoch Experimente gegeben, welche die Messung nicht bestätigen konnten. Auch sie fanden das Pentaquark nicht. Gibt es das Teilchen also gar nicht? Redox Pioneer: Professor Helmut Sies. PubMed Central. Abstract Professor Helmut Sies Dr.
Helmut Sies MD, is recognized as a Redox Pioneer, because he authored five articles on oxidative stress, lycopene, and glutathione, each of which has been cited more than times, and coauthored an article on hydroperoxide metabolism in mammalian systems cited more than times Google Scholar.
In early research, he first identified hydrogen peroxide H2O2 as a normal aerobic metabolite and devised a method to quantify H2O2 concentration and turnover in cells. He first described ebselen, a selenoorganic compound, as a glutathione peroxidase mimic. He contributed a fundamental discovery to the physiology of GSH, selenium nutrition, singlet oxygen biochemistry, and health benefits of dietary lycopene and cocoa flavonoids.
He has published more than articles, of which are cited at least times, and edited 28 books. His h-index is During the last quarter of the 20th century and well into the 21st, he has served as a scout, trailblazer, and pioneer in redox biology. His formulation of the concept of oxidative stress stimulated and guided research in oxidants and antioxidants; his pioneering research on carotenoids and flavonoids informed nutritional strategies against cancer, cardiovascular disease, and aging; and his quantitative approach to redox biochemistry provides a foundation for modern redox systems biology.
Helmut Sies is a true Redox Pioneer. Redox Signal. The joy of exploring the unknown and finding something novel and noteworthy: what a privilege! Bei allen Patienten konnte durch die Kombinationstherapie ein gutes lokales Ansprechen erreicht werden.
