The genus Stapelia belongs to the family Asclepiadaceae, which comprises a group of some 50 species, which have been used in medicine for their anti-inflammatory and antiarithritic properties . The presence of alkaloids in the genus Stapelia was first reported by Keller , where hordenine was isolated from the aerial part of S. gigantea. In addition, Meyer et al. reported the detection of N -met...

introduction: the main agents of sarcocystosis in cattle as an intermediate host include s. cruzi, s. hominis and s. hirsuta. a sensitive and specific tool such as molecular-based techniques would be necessary to identify the species. case report: after collection of beef sample from yazd slaughterhouse, dna extraction was done with salting out method. the 18srrna gene as a specific target gene...

BACKGROUND Leaves of Lomatia hirsuta are used in traditional medicine in Chile under the common name of "radal". A tea of radal is traditionally used for treatment of cough, bronchial troubles, and asthma. In a preliminary screening, extracts of the leaves revealed antifungal activity, and the present phytochemical study was undertaken to explain this activity and support the traditional use. ...

Introduction of the Sym plasmid pRL1JI into the cured Rhizobium leguminosarum bv. trifolii strain RCR5 resulted in a strain, designated RBL5523, that was expected to nodulate plants of the pea cross-inoculation group. However, effective nodulation occurred only on Vicia sativa plants, not on V. hirsuta or Pisum sativum. After random Tn5 mutagenesis, a derivative of RBL5523 was isolated that eff...

The genus Xiruana Brescovit, 1997 is currently composed of four South American species: X. gracilipes (Keyserling) from Brazil, Bolivia and Argentina, X. affinis (Mello-Leitão) from Brazil, X. hirsuta (Mello-Leitão) from Venezuela, Brazil, Paraguay, Argentina and Uruguay, and X. tetraseta (Mello-Leitão) from Venezuela, Brazil and Paraguay. Of these, the last three are redescribed in this paper,...

In this paper, a facile and green approach for the synthesis of silver oxide nanoparticles Ag2O NPs was performed using extract wild plant Herniaria hirsuta (H. hirsuta). Different spectral methods were used characterization biosynthesized NPs, ultraviolet-visible (UV-Vis) spectroscopy gave surface plasmon resonance (SPR) peak is 430 nm, estimation direct indirect forbidden gap bands are respec...

Hoplitis bees of the Palaearctic subgenus Stenosmia (Megachilidae) inhabit deserts and semideserts between southern Spain and eastern Asia. They nest in excavated burrows in the soil and collect pollen from plant taxa that typically grow in desert areas, such as Frankenia (Frankeniaceae), Peganum (Nitrariaceae), Tamarix (Tamaricaceae) or Zygophyllum (Zygophyllaceae). The taxonomic revision of t...
