A rapid micropropagation system for Scabiosa tschiliensis Grunning, an ethnic medicinal plant, has been developed. Calluses were induced from leaf and petiole explants on Murashige and Skoog (MS) medium supplemented with 2.0 mg l−1 thidiazuron and 0.5 mg l−1 2,4-dicholorophenoxyacetic acid. In this medium, callus induction rate was about 94.05 %.(More)
OBJECTIVE Endothelin-1 is a potent vasoconstrictor derived from vascular endothelium. Elevated endothelin-1 levels are observed in a host of cardiovascular pathologies including cardiomyopathy. The epigenetic mechanism responsible for endothelin-1 induction in these pathological processes remains elusive. APPROACH AND RESULTS We report here that induction(More)
Transforming growth factor (TGF-β) induced activation of portal fibroblast cells serves as a primary cause for liver fibrosis following cholestatic injury. The underlying epigenetic mechanism is not clear. We studied the role of a transcriptional modulator, megakaryoblastic leukemia 1 (MKL1) in this process. We report here that MKL1 deficiency ameliorated(More)
This paper proposes a new fragile watermarking algorithm which is mainly applied to binary document image based on the wet paper code. In order to improve embedding capacity and locating tampered area, some work is done base on the prior research of fragile in this paper. First, we dynamically adjust the bits which are embedded into image according to the(More)
In order to solve the conflict with robustness and invisibility of video watermark, the algorithms proposed in this paper select certain blocks according to the texture. By using the binary image to deal with logistic chaotic map and error-correction coding as watermarked data can improve the robustness and security. The low frequency signals of the(More)
