many different plant species synthesize triterpenoid saponins as part of their normal programme of growth and development. examples include plants that are exploited as sources of drugs. interest in these molecules stems from their medicinal properties, antimicrobial activity, and their likely role as determinants of plant disease resistance. daisy (bellis perennis l.) accumulates triterpenoid ...

Phylogenetic analyses of nrITS sequences of Asteraceae revealed that the Bellis group is a natural assemblage comprising all the species of Bellis and Bellium, but not Rhynchospermum. In contrast, we propose to include the genera Bellis, Bellium, and Bellidastrum in the subtribe Bellidinae in the interest of circumscribing natural groups. Our results also suggest an early diversification in the...

Thrombocytopenia is a common problem experience by cancer patients, which usually results from the use of conventional chemotherapy and at times is a dose limiting factor for chemotherapy administration. The incidence of thrombocytopenia among solid cancer patients is rather low i.e., ranging betwe...

BACKGROUND The chasmosaurine ceratopsid Chasmosaurus is known from the Upper Cretaceous (Campanian) Dinosaur Park Formation of southern Alberta and Saskatchewan. Two valid species, Chasmosaurus belli and C. russelli, have been diagnosed by differences in cranial ornamentation. Their validity has been supported, in part, by the reported stratigraphic segregation of chasmosaurines in the Dinosaur...
