Analysis of Stochastic Bifurcation in the Nonlinear Muscular Blood Vessel System
Traditional linear method is, in our opinion, not satisfactory in solving the stochastic response and bifurcation of the intrinsically nonlinear muscular blood vessel system. So we propose nonlinear method and...

Open AccessUp-regulation of miR-224 promotes cancer cell proliferation and invasion and predicts relapse of colorectal cancer
MicroRNAs (miRNAs) are small, non-coding RNAs that can function as oncogenes or tumor suppressors in human cancer. Abnormally expressed miR-224 was found to play a fundamental role in several types of cancer. ...
