Evaluation of the influence of radiation-induced cohort effect in cell populations receiving different doses.

Purpose: A non-targeted effect called radiation-induced cohort effect, which results in interactions among irradiated neighboring cells through cellular communication, has been reported. In high-precision radiotherapy, the dose is localized to the tumor, and rapid spatial changes occur in dose distribution. However, the effect of irradiating a population of cells with non-uniform doses remains unknown.

Electrochemical Properties and Electrochromism of 6-Aryl-1,3-bis(trimethylsilyl)fulvenes and Their Derivatives.

In this study, we have disclosed intriguing electrochromic properties of 6-aryl-1,3-bissilylfulvenes. The electrolyte solutions (0.1 M -BuNClO in acetonitrile or dichloromethane) of some 6-aryl-1,3-bissilylfulvenes showed notable color changes when superimposed negative voltages were applied to the solutions.
