The photofragmentation of butyrophenone yields benzoate and a propyl radical on oxidized TiO2(110). Oxygen dissociates in native oxygen vacancies to produce reactive oxygen adatoms which react with butyrophenone to create photoactive butyrophenone-O complexes that are sensitive to hole oxidation created upon UV illumination. The same O adatoms also trap one ...

When plants are exposed to stress, generation of reactive oxygen species (ROS) is often one of the first responses. In order to survive, cells attempt to down-regulate the production of ROS, while at the same time scavenging ROS. Photorespiration is now appreciated as an important part of stress responses in ...

Medical professionals initially only had insulin at their disposal when they wished to lower glucose levels pharmacologically in their patients with diabetes. It took over three decades (from the early 1920's to mid-1950's) before the next pharmaceuticals - sulfonylureas - appeared on the horizon to help lower glucose levels. The ...

WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Retrospective data have suggested an increased survival benefit for patients undergoing partial nephrectomy compared to radical nephrectomy, possibly as a result of the avoidance of long-term renalin sufficiency and subsequent sequelae. However, recent level-one evidence has questioned this benefit. ...

Introduction: The introduction of antibodies directed against tumour necrosis factor (anti-TNF) has dramatically changed the concept of treating patients with Crohn's disease (CD). Unfortunately, the long-term efficacy of anti-TNF agents may be hampered by immunogenicity. The availability of more anti-TNF agents in the therapeutic armamentarium would therefore be of great ...
