Many studies have been made to develop walking anthropomorphic robots able to move in environments well-adapted to human beings and able to cooperate with them. Among the more advanced projects of humanoid robots, one can mention : the Honda robots P2, P3 (Hirai, 1997) (Hirai et al., 1998) and Asimo (Sakagami et al., 2002), the HRP series developed by AIST (Kaneko et al., 1998) (Kajita et al., ...

Atomic force microscopy (AFM), invented in 1986, expanded the application of scanning tunneling microscopy to nonconductive, soft, and live biological samples (Binnig et al., 1986; Hansma et al., 1988; Marti et al., 1988; Drake et al., 1989). AFM has several capabilities, including characterizing topographic details of surfaces from the submolecular level to the cellular level (Radmacher et al....

Osteosarcoma is one of the most common malignant bone tumors in children and adolescents (Meyers et al., 1998; Bacci et al., 2000; Hauben et al., 2003; Chano et al., 2004; Marina et al., 2004; Benassi et al., 2007). The present therapeutic strategies in clinical applications have low efficiency under the current osteosarcoma therapy (Huang et al., 2012; Choeyprasert et al., 2013). Therefore, ne...

Reactive oxygen species (ROS) are versatile molecules mediating a variety of cellular responses in plant cells, including programmed cell death (PCD), development, gravitropism, and hormonesignaling. A picture showing how ROS function in signal transduction networks has started to emerge as the result of recent studies providing genetic, cell biological, and physiological evidence describing ro...
