...er safety features. The hooks of the electrode are fixed within the liver tissue when deployed so no needle movement is possible during RFA, which makes the procedure safer, and no electrode cooling is required during ablation, making the procedure easier and quicker. For the study, the researchers, analyz...Personalized immunosuppression with leading organ transplant therapy may optimize patient care
.... The OptiCept TM study will compare traditional fixed dosing of CellCept with personalized dose adjustment based on measurement of CellCept blood concentrations.
