CRISPR/Cas9 is a versatile genome-editing technology that is widely used for studying the functionality of genetic elements, creating genetically modified organisms as well as preclinical research of genetic disorders. However, the high frequency of off-target activity (≥50%)-RGEN (RNA-guided endonuclease)-induced mutations at sites other than the intended(More)
Dysregulated microRNA (miRNA) expression has a critical role in tumor development and metastasis. However, the mechanism by which miRNAs control melanoma metastasis is unknown. Here, we report reduced miR-98 expression in melanoma tissues with increasing tumor stage as well as metastasis; its expression is also negatively associated with melanoma patient(More)
Signal transducer and activator of transcription 3 (STAT3) is usually constitutively activated in a variety of malignancies. Thus, STAT3 may be a promising target for treatment of tumor cells. Recently, Tanshinone IIA (Tan IIA), a major active constituent from the root of Salvia miltiorrhiza Bunge, was reported to have apoptosis inducing effects on a large(More)
Tea is one of the most consumed beverages worldwide. The healthy effects of tea are attributed to a wealthy of different chemical components from tea. Thousands of studies on the chemical constituents of tea had been reported. However, data from these individual reports have not been collected into a single database. The lack of a curated database of(More)
We demonstrate that the combination of simply contracted basis functions and the Lanczos algorithm yields an extremely efficient method for computing vibrational energy levels. In this paper we discuss the ideas, and present some results for CH4. The basis functions we use are products of eigenfunctions of reduced-dimension Hamiltonians obtained by freezing(More)
A rationally designed glycyl-glycine derivative containing a light cleaved pyrenylmethyl ester tail was covalently bound onto the surface of quartz template. The interface self-assembly of this dipeptide building block induced the formation of chemically bound vertically aligned nanorods (CBVANs) with light sensitivity on the template.
In this paper, we try to detect and track maneuverable birds in captured videos for further automatic research. To avoid abrupt scene change, videos are captured by pointing the camera upwards and making the image against the sky. Two levels (pixel level and frame level) background update algorithm is used to get the foreground in real time. In frame level,(More)
