Selective schools closures has been considered as a means of reducing transmission between children and hence reducing the number of cases at the peak of an epidemic but new research led by researchers at the University of Warwick shows that limited school closures are ineffective and that only significant widespread school closures would have real effect on the spread of a epidemic and the strain placed on hospital intensive care units.
While the development of therapies designed to block "checkpoints" within the immune system has been one of the most exciting and noteworthy advances in cancer research in recent years, it's also been one of the most puzzling, leaving researchers to ask: Why don't these new therapies work for more patients, and why is their efficacy in controlling cancerous tumors often short-lived? A research team from Roswell Park Cancer Institute has shown that at least one answer -; and an excellent opportunity for unleashing the full potential of these promising immunotherapies -; may lie in the body's "fight or flight" reaction to stressors and in drugs already widely used to control and temporarily disable this stress response.
Photoplethysmography (PPG) is a simple optical technique used to detect volumetric changes in peripheral blood circulation. It's used in smart watches, for example, to monitor pulse and heart rate, but PPG biosensors are also found in millions of smartphones, but without any current clinical applications.
New research helps to explain why some commonly used drugs come with a serious downside: They up your odds of breaking a bone. The drugs in question, glucocorticoids (e.g. cortisone and prednisone) and the insulin sensitizer rosiglitazone work through entirely different mechanisms as therapies for inflammatory diseases and diabetes respectively, and two studies in the June issue of Cell Metabolism now show that they lead to bone loss in different ways too.
