c-Jun N-terminal kinase (JNK) is located in focal adhesion plaque (FAP). JNK is necessary to growth, morphogenesis, and differentiation of cells; especially JNK1 has a close relation with tumors. In this study, we silenced JNK1 by using short hairpin RNA (shRNA) and examined the effect on migration and invasion of mouse hepatocellular carcinoma (HCC) cell(More)
Purpose: To set up a molecular method (i.e. RT-PCR) that can be used to detect disseminated tumor cells (DTCs) in regional lymph nodes (LNs) in patients with lung cancer and to evaluate its clinical significance. Methods: Cytokeratin 19 (CK19) was used as marker. Serial dilution study for LC-5 cells (a lung squamous cell line) was performed to detect(More)
In this paper, we propose a data hiding scheme with high capacity in steganography. First of all, we improve the data hiding technique based one neighbor mean interpolation for increasing the image quality of a stego-image without losing any capacity. A stego-image is derived from a cover image which has embedded the secret data. A cover image is generated(More)
This paper proposes a novel visible watermarking scheme that is based on dynamic images and preserves context integrity. In our approach, the watermark is divided into many sub-watermarks, and then we utilize the visible watermark method to hide the sub-watermarks into difference images. When the dynamic image with the hidden watermark is done, the human(More)
User authentication over the Internet has long been an issue for Internet service providers and users. A good authentication protocol must provide high security and mutual authentication on both sides. In addition, it must balance security and usability, which has been shown in the literature to be a difficult problem. To solve this problem, we propose a(More)
