Fatty acid synthase (FAS) is considered as a novel drug target for the development of anticancer and anti-obesity agents. Bioassay-guided fractionation of a n-hexane-soluble extract prepared from the roots of Salvia miltiorrhiza Bunge (Labiatae), using an in vitro enzyme assay, led to the isolation of five abietane diterpenoids: 15,16-dihydrotanshinone I(More)
Asari Radix, the roots of Asarum heterotropoides F. Maekawa var. manshuricum F. Maekawa or A. sieboldii F. Maekawa, has traditionally been used for the treatment of various infectious diseases. Since its MeOH extract inhibited the growth of Listeria monocytogenes in a preliminary test, the aim of this study was to isolate and identify the anti-listerial(More)
In this paper, in order to improve fairness index of TCP flows, we propose the TSW3CDM_FS(Time Sliding Window Three Color Dynamic Marker with Flow Status) based on average transfer rate estimation. The proposed algorithm is based on dynamic marking policy that allocates band-width in proportion to transmission rate of flows. From simulation results, the(More)
One of the key problems in the application of optical burst switching is the handling of burst contention when two or more incoming burst are directed to the same output line. Various techniques for resolving contention problems have been examined and generally classified as wavelength translation, buffering, and deflection routing. Deflection routing is(More)
