20130202566 | METHOD FOR INDUCING DIFFERENTIATION OF MESENCHYMAL STEM CELLS TO NERVE CELLS USING SOUND WAVES - The present invention relates to a method for differentiation of mesenchymal stem cells. More specifically, the invention relates to a method for differentiating mesenchymal stem cells to neural cells by treating the mesenchymal stem cells with low-frequency sound waves. The differentiation method of the present invention can induce differentiation even with low-cost media rather than induced neural differentiation mediums which are expensive due to addition of growth factors, and the neural cells differentiated according to the present invention may be useful for treatment of neurological diseases. | 08-08-2013 |

20090001485 | Semiconductor Device and Manufacturing Method Thereof - Disclosed is a semiconductor device that can be used as a high voltage transistor. The semiconductor device can include a gate electrode on a semiconductor substrate, drift regions in the substrate at opposite sides of the gate electrode, a source region in one of the drift regions and a drain region in the other of the drift regions, and a shallow trench isolation (STI) region in a portion of the drift region between the gate electrode and the drain region. The portion of the drift region below the STI region can have a doping profile in which the concentration of impurities decreases from the concentration at the lower surface of the STI region, and then increases, and then again decreases. | 01-01-2009 |
