The milkweed, Calotropis gigantea (L.) W.T. Aiton (Gentianales: Asclepiadaceae) locally known as Akond, is an evergreen, perennial shrub, and is widely distributed in sub-tropical and tropical countries. It has been reported that latices of the milkweeds including C. gigantea contain cardiac glycosides that vary in amount and type between species, between various plant parts of the same species...

Monoclonal antibodies were raised against cystozoites of Sarcocystis muris and characterised. Twelve monoclonal antibodies reacted in the ELISA, Dot-ELISA and IFAT only with homologous antigen. The other twelve showed cross reactions of various degrees with cystozoites of S. gigantea, S. tenella, S. arieticanis, S. capracanis, S. miescheriana and S. suihominis. Proteins of S. arieticanis, S. te...

Chromosome numbers and 2C-values of six Byblis species were determined to investigate the chromosome differentiation genome diversity in this genus. Somatic B. liniflora complex showed diploid tetraploid 2n=16 32. In contrast, number gigantea, which belongs gigantea complex, displayed only 2n=36. The 2C DNA contents across all studied over a three-fold range, from lowest value 2C=0.64 pg rorida...

Background: Calotropis gigantea of family Asclepiadaceae, is traditionally used in ayurveda for its anti-helminthic, anti-pyretic, and anti-malarial activities. The present study was designed to investigate the sub-acute toxic effects of ethanol and methanol extract of Calotropis gigantea latex in mouse model using haematology, serum biochemistry and histopathological changes as toxicity indice...

Creeping bentgrass (Agrostis stolonifera) and redtop (A. gigantea) are introduced turfgrasses that are naturalized throughout the northern U.S. Interest in creeping bentgrass has risen following the 2003 escape of a genetically modified (GM), herbicide-resistant cultivar near Madras, Oregon. The objectives of this study were to characterize the floristic attributes of the plant communities asso...

A motivational model of alcohol involvement (M. L. Cooper, M. R. Frone, M. Russell, & P. Mudar, 1995) was replicated and extended by incorporating social antecedents and motives and by testing this model cross-sectionally and longitudinally in a sample of college students. Participants (N = 388) completed a questionnaire battery assessing alcohol use and problems, alcohol expectancies, sensatio...

Festuca rubra is an abundant supratidal grass on sub-arctic James Bay (Canada) shorelines, forming extensive near-monocultures that are used as forage by nesting and migrating geese. Studies at other, more northern North American locations have shown grubbing by geese can have severe consequences for intertidal and supratidal marshes, but these studies have focussed on plant communities that di...

As part of a scientific appraisal of some of the folkloric and ethnomedical uses of Calotropis gigantea L. (Family: Asclepiadaceae), the present study was designed to evaluate the antitumour activity of the Calotropis gigantea flower against Ehrlich’s ascites carcinoma (EAC) by using a crude ethyl acetate extract from the flower of Calotropis gigantea (designated as EECF) in Swiss mice. EECF wa...

The methanol extracts of three Macaranga species (M. denticulata, M. pruinosa, and M. gigantea) were screened to evaluate their total phenolic contents and activities as cholinesterase inhibitors, nitric oxide (NO) production inhibitors, tyrosinase inhibitors, and antioxidants. The bark of M. denticulata showed the highest total phenolic content (2682 mg gallic acid equivalent (GAE)/100 g) and ...

Market-based, supply-side interventions such as domestication, cultivation, and wildlife farming have been proposed as legal substitutes for wild-collected plants and animals in the marketplace. Based on the literature, we devised a list of the conditions under which supply-side interventions may yield positive conservation outcomes. We applied it to the trade of the orchid Rhynchostylis gigant...
