The activity of therapeutic molecular cluster Ag5 is dependent on oxygen level and HIF-1 mediated signalling.

Regions of hypoxia occur in most solid tumours and are known to significantly impact therapy response and patient prognosis. Ag5 is a recently reported silver molecular cluster which inhibits both glutathione and thioredoxin signalling therefore limiting cellular antioxidant capacity. Ag5 treatment significantly reduces cell viability in a range of cancer cell lines with little to no impact on non-transformed cells.

Report on the current status of the use of real-world data (RWD) and real-world evidence (RWE) in drug development and regulation.

Radically expanding use of real-world data (RWD) and real-world evidence (RWE) holds the potential to substantially impact drug development, pharmaceutical regulation, and payment within health care systems. Central to this is the reconfiguration of data gathering and transformation of data to information, which can be used as evidence for decision making. We discuss applications of this paradigm in the light of recent developments in both the United States and Europe on RWD and RWE.

Response of protein S100B to playing American football, lifting weights, and treadmill running.

Objective: To determine if serum S100B increases similarly as a result of playing American football compared to exercise alone.

Methods: Serum S100B was measured in division III collegiate football players before and after every home game during a single football season. Serum S100B was also measured before and after subjects walked on a treadmill for 30 minutes at a leisurely pace, ran on a treadmill while wearing and not wearing a football helmet at 6 mph for 8 minutes, and performed low-, moderate-, or high-intensity resistance exercise.
