A new minor polyoxygenated triterpene named glutinolic acid (1) and two new aeginetic acid quinovosides (2, 3) were isolated from the roots of Rehmannia glutinosa LIBOSCH. (Scrophulariaceae) cultivated in Gunwi-gun, Korea. The structures of these compounds were established as 3α,19α,20β,24,30-pentahydroxyurs-12-en-28-oic acid (1, glutinolic acid), aeginetic acid 5-O-β-D-quinovoside (2) and aegi...

and Applied Analysis 3 At resonance levels, ur should be arbitrary, and then we are deducing a nonlinear equation g ur−1 · · ·u0, φ · · · 0. If the equation f implies g, then the compatibility condition is unconditionally satisfied. An equation for which these three steps can be carried out consistently and unambiguously passes the Painlevé test. Equation 1.3 is called the truncated Painlevé ex...

Glycogen synthase kinase-3 (Gsk-3) is a key regulator of multiple signal transduction pathways. Recently we described a novel role for Gsk-3 in the regulation of DNA methylation at imprinted loci in mouse embryonic stem cells (ESCs), suggesting that epigenetic changes regulated by Gsk-3 are likely an unrecognized facet of Gsk-3 signaling. Here we extend our initial observation to the entire mou...

To determine the magnitude of Plasmodium vivax relapsing malaria in rural Amazonia, we carried out a study in four sites in northeastern Peru. Polymerase chain reaction-restriction fragment length polymorphism of PvMSP-3α and tandem repeat (TR) markers were compared for their ability to distinguish relapse versus reinfection. Of 1,507 subjects with P. vivax malaria, 354 developed > 1 episode du...

Dynamic Voltage Scaling techniques allow the processor to set its speed dynamically in order to reduce energy consumption. It was shown that if the processor can run at arbitrary speeds and uses power s when running at speed s, the online heuristic AVR has a competitive ratio (2α)/2. In this paper we first study the online heuristics for the discrete model where the processor can only run at d ...
