By Fleshker, Shimrit Preise, Dina; Kalchenko, Vyacheslav; Scherz, Avigdor; Salomon, Yoram ABSTRACT This study hypothesized that success rate assessment of vascular targeted photodynamic therapy (VTP) of solid tumors 24 h posttreatment may allow prompt administration of a second treatment in case of failure, increasing the overall success rate. Here, we show that treatment of luciferase transfected CT26-luc mouse colon carcinoma tumors in BALB/c mice by VTP with WST11 (a Pd-...

The man-made molecular complexes enter cancer cells and, when signaled, deliver killing medicine or cause the cell to change. The new supermolecules have more units that will absorb light "“ providing more control over the range of light frequencies that can be included and excluded as signals and the responses....
