Among the nine Echinacea species, E. purpurea, E. angustifolia and E. pallida, have been widely used to treat the common cold, flu and other infections. In this study, ethanol extracts of these three Echinacea species and E. paradoxa, including its typical variety, E. paradoxa var. paradoxa, were screened in lipopolysaccharide (LPS)-stimulated macrophage cells to assess potential anti-inflammat...

The Afrotropical butterfly subfamily Pseudopontiinae (Pieridae) was traditionally thought to comprise one species, with two subspecies (Pseudopontia paradoxa paradoxa Felder & Felder and Pseudopontia paradoxa australis Dixey) differing in a single detail of a hindwing vein. The two subspecies also differ in their known geographic distributions (mainly north of versus south of the equator). Unli...

In this study, dual culture, poison agar, and direct methods were used to assess the ability of Trichoderma virens IMI-392430, T. pseudokoningii IMI-392431, T. harzianum IMI-392432, T. harzianum IMI-392433, and T. harzianum IMI-392434 to control Ceratocystis paradoxa, which causes the pineapple disease of sugarcane. The highest percentage inhibition of radial growth (PIRG) values were observed ...

Finding of two undescribed species, closely related to Eresiomera paradoxa (Schultze, 1917) in Liberia and the Democratic Repubic of Congo led the authors to revise the material available in the African Butterfly Reserarch Institute (ABRI), Nairobi. Examination of the material revealed that the placement of E. paradoxa and the related species neither in the genus Eresiomera Clench, 1965, nor in...

One of ultimate human-machine interfaces is anthropomorphic spoken dialog agent which behaves like humans with facial animation and gesture and make speech conversations with humans. Among numerous efforts devoted for such a goal, Galatea Project conducted by 17 members from 12 universities is developing an open-source license-free software toolkit [1] for building an anthropomorphic spoken dia...

We present a computational model of case-based visual problem solving. The Galatea model and the two experimental participants modeled in it show that 1) visual knowledge is sufficient for transfer of some problemsolving procedures, 2) visual knowledge facilitates transfer even when non-visual knowledge might be available, and 3) the successful transfer of strongly-ordered procedures in which n...

The Ceratocystis paradoxa complex accommodates a group of fungal pathogens that have become specialized to infect mostly monocotyledonous plants. Four species currently are recognized in this group, including C. paradoxa, which has a widespread distribution and broad host range. In this study, multigene phylogenetic analyses involving sequences of the ITS, β-tubulin and TEF-1α gene loci, in com...
