Disease relevance of Cyperus


High impact information on Cyperus

  • Biosynthetic pathway of insect juvenile hormone III in cell suspension cultures of the sedge Cyperus iria [2].
  • One of these compounds, juvenile hormone III (JH III), has also been identified in the sedge Cyperus iria [2].
  • In this study, the uptake of NG and 2,4-DNT from water by three common grasses, yellow nutsedge (Cyperus escalantus), yellow foxtail (Setaria glauca), and common rush (Juncus effusus), was investigated using hydroponic reactors [3].
  • Bioassays showed that both the flavone and cyclohexenone significantly inhibited the growth of weeds Echinochloa crus-galli, Cyperus difformis and Cyperus iris, and the spore germination of fungal pathogens Pyricularia oryzae and Rhizoctonia solani at all tested concentrations [4].
  • Six new sesquiterpenes, cyperusols A(1) (1), A(2) (2), B(1) (3), B(2) (4), C (5), and D (6), together with two monoterpenes and 13 sesquiterpenes were isolated from an Egyptian herbal medicine, the whole plants of Cyperus longus [5].

Biological context of Cyperus


Anatomical context of Cyperus

  • In Xenopus oocytes expressing receptors, using electrophysiological measurement, extracts of rhizomes of Cyperus articulatus (300 microg/ml) inhibited 50% of the EC(50) and EC(80) of glutamate (1.3 and 2.9 microM, respectively) induced inward current through hNMDAR1A/2A receptors [7].

Associations of Cyperus with chemical compounds


Gene context of Cyperus

  • Water extracts from rhizomes of Cyperus articulatus dose-dependently reduced spontaneous epileptiform discharges and NMDA-induced depolarizations in the rat cortical wedge preparation at concentrations at which AMPA-induced depolarizations were not affected [12].
  • Evaluation of resistance in Cyperus difformis populations to ALS inhibiting herbicides [6].

Analytical, diagnostic and therapeutic context of Cyperus

  • Samples of field corn (Zea mays) (n = 111) and chufa (Cyperus esculentus) (n = 20), obtained in 1987, 1988 and 1989 on the Mississippi Sandhill Crane National Wildlife Refuge (MSCNWR) and nearby private lands were analyzed for aflatoxin B1(AB1), ochratoxin A and sterigmatocystin using thin layer chromatography [13].
