Tanacetum vulgare L. (Tansy) has been extensively used in folk medicine for treatment of a variety of medical disorders. In the present study, we isolated and purified four acidic polysaccharide fractions (designated T-I to T-IV) from Tansy florets by the sequential use of hot-water extraction, ethanol precipitation, ultra-filtration, anion-exchange, and size-exclusion chromatography. The avera...

PREMISE OF THE STUDY We screened 10 microsatellite loci for the dioecious, rainforest tree Aextoxicon punctatum, a species belonging to a monotypic family and genus, endemic to southwestern South America (30-43°S). METHODS AND RESULTS Polymorphisms were evaluated in 108 adult trees from four populations, including the northern and southern extremes of the geographic range of Aextoxicon in Chi...

After several years collecting in the type-localities and studying representative samples of genus Steindachneridion Eigenmann & Eigenmann, 1919 from Brazilian and foreign museums, a taxonomic revision of the Recent species of the genus is presented, including the description of a new species from the rio Iguaçu, above the great falls. Steindachneridion species are large sized fishes, reaching ...

A new type of extracellular fibril is described in the dermis of Bufo marinus, Rana pipiens, and Amblystoma punctatum. It is restricted in distribution to the dermal micropapillae and the region immediately below them in the stratum spongiosum. The fibrils (diameter = 200 to 750 A) are lateral aggregates of fine filaments and have a unique banding pattern characterized by absence of recognizabl...

A taxonomic study on the solitary wasps in the vespid genus Anterhynchium de Saussure, 1863, from Vietnam is presented. One species previously identified as A. (Anterhynchium) abdominale abdominale (Illiger, 1802) is described as new, namely A. punctatum Nguyen, sp. nov. Antechynchium (Dirhynchium) flavolineatum flavolineatum (Smith, 1857) and A. (Dirhynchium) flavomarginatum flavomarginatum (S...

Gene sequence data from the small-subunit ribosomal RNA coding region were used to explore evolutionary relationships among the colonial spumellarian radiolaria (Polycystinea). Representatives from the two spumellarian families known to form colonies were considered including the following taxa: Sphaerozoidae: Collozoum pelagicum; Collozoum serpentinum; Rhaphidozoum acuferum; Sphaerozoum puncta...
