Phosphocreatine (PCr) is a natural compound, which can donate high-energy phosphate group to ADP to synthesize ATP, even in the absence of oxygen and glucose. At present, it is widely used in cardiac and renal ischemia-reperfusion (IR) disease. In this study, to examine the protective efficacy of PCr against cerebral IR, disodium creatine phosphate was(More)
For 2D vector maps, obtaining good tamper localization performance and original content recovery with existing reversible fragile watermarking schemes is a technically challenging problem. Using an improved reversible watermarking method and a fragile watermarking algorithm based on vertex insertion, we propose a reversible fragile watermarking scheme that(More)
Coumarins are main active components of Peucedanum praeruptorum Dunn. Among them, methoxylated coumarin compound, such as bergapten, xanthotoxin, and isopimpinellin, has high officinal value and plays an important role in medicinal field. However, major issues associated with the biosynthesis mechanism of coumarins remain unsolved and no corresponding(More)
Surface-amorphous and oxygen-deficient Li3VO4-δsynthesized by simple annealing of Li3VO4 powders in a vacuum shows great enhancements in both reversible capacity and coulombic efficiency for the first discharge/charge without delicate size control and carbon coating. The results are associated with the improved charge-transfer kinetics caused by the(More)
The author regrets that the original version of this article contain four errors. The author did not consider the first vertex and the last vertex of each polygon/polyline during the experiments, the results of proposed method in Table 2, the last column of Tables 7 and 8, and Fig. 5 was wrong. The author, therefore, has corrected errors as follows. The(More)
Dear Editor, Rearrangements involving mixed lineage leukemia (MLL) are common chromosome aberrations in infant, pediatric and adult acute leukemia, which are generally associated with poor prognosis. To date, more than 79 partner genes have been identified [1]. MLL fusion partners can be classified into four groups: nuclear proteins (MLLT3, MLLT10, and(More)
