The safety and efficacy of robotic image-guided radiosurgery system treatment for intra- and extracranial lesions: a systematic review of the literature.

Background: The CyberKnife is a new, frameless stereotactic radiosurgery system. This work reviews its safety and efficacy in the treatment of intra- and extracranial lesions.

Methods: A literature search was made of the Medline, Embase, Pascal Biomed, CINAHL and Cancerlit databases.

Time-resolved fluorescence of DAPI in solution and bound to polydeoxynucleotides.

Fluorescence decay studies, obtained by multifrequency phase-modulation fluorometry, have been performed on DAPI in solution and complexed with natural and synthetic polydeoxynucleotides. DAPI decay at pH 7 was decomposed using two exponential components of 2.8 and 0.
