The anti-Trypanosoma cruzi activity of extracts from 13 Argentinean Asteraceae species was determined. Dichloromethane and methanol extracts of Acmella bellidioides, Aspilia silphioides, Viguiera tuberosa, Calyptocarpus biaristatus, Hyalis argentea, Helenium radiatum, Gaillardia megapotamica, Verbesina subcordata, Gymnocoronis spilanthoides, Viguiera anchusaefolia, Thelesperma megapotamicum, Ze...

Suspension cultures of Pueraria tuberosa, a woody legume, have been established and using different concentrations of growth regulators, sucrose, ammonium and nitrate nitrogen, attempts have been made to improve their isoflavonoid content. The cell cultures grew well on all the treatments. Up to approximately 8 folds increased isoflavonoids content was recorded in the cultures grown in MS mediu...

Abstract: A methanol extract of the roots of Stemona tuberosa (Stemonaceae) significantly inhibited lipopolysaccharide-induced nitric oxide production in murine BV2 microglial cells. Eight alkaloids tuberostemonine K (1), neotuberostemonine (2), oxotuberostemonine (3), bisdehydroneotuberostemonine (4), epibisdehydrotuberostemonine J (5), bisdehydrotuberostemonine (6), tuberostemoninol (7), and ...

Phlomis tuberosa L. (Lamiaceae) is a flowering perennial plant, native to Eurasia, and sparsely distributed in Bulgaria. The species has been proved accumulate flavonoids, iridoids, phenolic glycosides, as well essential oil. To now, there no information on the chemical content of Bulgarian oil from plant. aim was study composition oils, obtained species. Four different samples were studied – o...

Objective: The current study was planned to investigate the anti-carcinogenic & anti-oxidant property of Ruellia tuberosa L. (Acanthaceae) methanolic leaf extract (MERTL) on HepG2 cell line & RAW 264.7 murine macrophage cell lysate respectively. Methods: The potent cytotoxic activity of MERTL has been studied by cell growth inhibition study & MTT assay on metabolically active HepG2 cells. 1% Ag...

Epigenetic changes are crucial for the generation of immunological memory. Failure to generate or maintain these changes will result in poor memory responses. Similarly, augmenting or stabilizing the correct epigenetic states offers a potential method of enhancing memory. Yet the transcription factors that regulate these processes are poorly defined. We find that the transcription factor Oct1 a...

Coexistence by a great number of species could reflect niche segregation at several resource axes. Differences in the use of a hilltop as mating site for a Eumaeini (Lycaenidae) community were measured to test whether niche segregation exists within this group. Specimens were collected throughout 21 samplings between July-October of 2004 and July-October of 2005. Two environmental variables and...

The isolation of Mycoplasma hyosynoviae from a piglet with severe pneumonia is described. This is the first report of M. hyosynoviae isolation in the country. The lung sample where the isolation was made was severely consolidated, suppurative and pleurisy. The pathogenicity of the M. hyosynoviae isolated has yet to be determined.

Three case studies involving two temperate Australian seagrass species – Pondweed (Ruppia tuberosa) and Ribbon Weed (Posidonia australis) highlight different approaches to their restoration. Seeds rhizomes were used in three collaborative programmes promote new scale up restoration outcomes.
