Validation of temporal optimization effects for a single fraction of radiation in vitro.

13 Nov 2009 PURPOSE: To experimentally validate how temporal modification of the applied dose pattern within a single fraction of radiation therapy affects cell survival. METHOD AND MATERIALS: Using the linear-quadratic model, we have previously demonstrated ... Read more...

The PPARalpha agonist fenofibrate preserves hippocampal neurogenesis and inhibits microglial activation after whole-brain irradiation.

30 Oct 2009 PURPOSE: Whole-brain irradiation (WBI) leads to cognitive impairment months to years after radiation. Numerous studies suggest that decreased hippocampal neurogenesis and microglial activation are involved in the pathogenesis of WBI-induced brain ... Read more...

Photodynamic treatment of culture medium containing serum induces long-lasting toxicity in vitro.

29 Sep 2009 Photodynamic therapy (PDT) produces singlet oxygen and reactive oxygen species (ROS) that damage tumor cells and the vasculature. The resulting effect is a balance between photo-oxidations through primary or secondary ROS and scavenging activity. ... Read more...
