Abstract: A method for evaluating an efficacy of a chemoradiotherapy against squamous cell carcinoma comprises the following steps (a) to (c): (a) detecting an expression level of at least one gene selected from a SIM2 gene and genes co-expressed with the SIM2 gene in a squamous cell carcinoma specimen isolated from a subject; (b) comparing the expression level detected in the step (a) with a reference expression level of the corresponding gene; and (c) determining that an efficacy of a chemoradiotherapy against squamous cell carcinoma in the subject is high if the expression level in the subject is higher than the reference expression level as a result of the comparison in the step (b).

Abstract: A mounting bed integral with a hammer bank is disposed parallel to a counter balancer composed of a counter balancer constituting member and a yoke. The mounting bed and the yoke are provided with solenoid coils opposed to a permanent magnet provided on the frame, and a pair of bearings are arranged between the mounting bed and the counter balancer constituting member. A position sensor for the mounting bed and the counter balancer is provided. A controller is provided to control a current and direction of the solenoid coil by a detection signal from the position sensor. The mounting bed integral with the hammer bank and the counter balancer are shuttle-operated in opposite directions by the controller.
