Bioassay-directed fractionation of the stem bark extract of Erythrina variegata L. has resulted in the isolation of three new isoflavones: 5,4'-dihydroxy-8-(3,3-dimethylallyl)-2''-methoxyisopropylfurano[4,5:6,7]isoflavone (1), 5,7,4'-trihydroxy-6-(3,3-dimethylallyloxiranylmethyl)isoflavone (2),(More)
In order to implement the real-time video compression system, the compression algorithm should be improved and also need a reasonable control framework which brings no additional overhead and efficient to use of the hardware resources. With the perspective of improve the degree of parallelism of the on-chip peripherals and the core, this paper(More)
To investigate the role of p38 MAPK in silicosis, we explored the effects of SB203580 as a specific inhibitor of p38 MAPK in the silicosis model in rats. Rats were exposed to 50mg/ml silica intratracheally. From the first day after instillation, rats were injected with SB203580 1mg/kg/d. Rats were sacrificed at 7 and 15days after exposure of silica. The(More)
Along with expansion of the network scale, much more attention has been paid to the information transmission among nodes in network and the resulted control problem. Therefore, the index of structural controllability is introduced in this paper to characterize the performance indices when network system can be controlled within finite time. Furthermore, an(More)
The main steam temperature is an important parameter to affect the economy and security of the generator. Due to the ultra supercritical units of the large capacity and high parameter, the main steam temperature control must be higher quality. However, main steam temperature of ultra supercritical unit has the characteristics of large time delay and(More)
Pituitary adenomas usually develop temozolomide resistance, which could compromise the anticancer effects of temozolomide. Suppression of hypoxia-inducible factor 1α has been shown to sensitize glioblastoma cells to temozolomide treatment according to previous reports. However, whether and how the suppression of hypoxia-inducible factor 1α could sensitize(More)
In the reference of ISO/IEC 9126 software quality model, this article establishes a comprehensive evaluation system of the software dependability. At the same time, it uses the concept of entropy to combine subjective weights and the entropy of objective weights to determine the weight values of measurements in the evaluation system. On this basis, take(More)
