Conventional Arti cial Intelligence and cognitive science have been argueing the emergence of intelligence by completely separating the system from its environment. In this paper, we will intensively investigate and analyze the role of the system-environment interaction through the comparison between the information processing and embodied cognitive approaches. By taking account of this interac...

The electronic absorption spectrum of 3-hydroxyflavone (3HF) in various solvents exhibits a long-wavelength (LW) band, whose origin has been debated. The excited-state dynamics of neutral and basic solutions of 3HF in alcohols upon excitation in this LW band has been investigated using a combination of fluorescence up-conversion and transient electronic and vibrational absorption spectroscopies...

Mononuclear manganese(II) and iron(III) flavonolates were synthesized as synthetic enzyme-substrate complexes, and their oxygenation reactions as biomimetic functional models with relevance to flavonol 2,4-dioxygenases are briefly described.

The polymeric title complex, [Co(C(8)H(8)O(5))(H(2)O)(2)](n) was synthesized by reaction of cobalt acetate with 7-oxabicyclo-[2,2,1]heptane-2,3-dicarb-oxy-lic anhydride. The Co(II) ion is six-coordinated in a distorted octa-hedral environment, binding to two water O atoms, to the ether O atom of the bicyclo-heptane unit, to two carboxyl-ate O atoms from two different carboxyl-ate groups of the ...

In the present study, we investigated the effect of Ginkgo biloba extracts and some of its individual constituents on the catalytic activity of human cytochrome P450 enzymes CYP1B1, CYP1A1, and CYP1A2. G. biloba extract of known abundance of terpene trilactones and flavonol glycosides inhibited 7-ethoxyresorufin O-dealkylation catalyzed by human recombinant CYP1B1, CYP1A1, and CYP1A2, and human...

Four known compounds, 5-Hydroxyflavone (1), 2’-Hydroxyflavanone (2), Paeonol (3) and bergenin (4), were isolated from the methanolic extract of the stem bark of Garcinia malaccensis for the first time through combination of vacuum and radial chromatography techniques. The structures of the secondary metabolites (1-4) were elucidated on the basis of their spectroscopic evidence and comparison wi...
