Medical Xpress / Why CAR T therapy works for some patients but fails for others may be getting clearer
Chimeric antigen receptor (CAR) T-cell therapy is one of oncology's most powerful ideas: Harvest a cancer patient's own immune cells, genetically engineer them to recognize tumor cells, multiply them in a laboratory and reinject ...
Medical Xpress / AI model could warn of cardiac arrest 10 to 15 minutes early
Perelman School of Medicine cardiologist Rajat Deo has been studying electrocardiographic (ECG) data and cardiac rhythms for nearly two decades at Penn. He says that every second, hospitals generate "enormous streams of ECG ...
