Environmental factors can lead individuals down different developmental pathways giving rise to distinct phenotypes (phenotypic plasticity). The production of winged or unwinged morphs in aphids is an example of two alternative developmental pathways. Dispersal is paramount in aphids that often have a metapopulation structure, where local subpopulations frequently go extinct, such as the specia...

Background and objective: Epilepsy one the most prevalent neurological illness which affects behavioral statuses like anxiety, depression and balance. Based on the anti-inflammatory and antioxidant properties of Tanacetum polycephalum, its effect on anxiety and depression caused by pentylenetetrazole (PTZ)-kindling in rats was investigated. Methods : In order to prepare the required extract, ae...

Ecological Role of Altitude on Quantitative Characteristics Caucasian Oak (Quercus macranthera Fisch. & C.A.Mey. ex Hohen.) Stands in Arasbaran Forest

OBJECTIVE Feverfew (Tanacetum parthenium L.) is a popular herbal remedy often advocated for the prevention of migraine. The aims of this systematic review are to update the evidence from rigorous clinical trials for or against the efficacy of feverfew for migraine prevention and to provide a safety profile of this herbal remedy. DESIGN Literature searches were performed using the following da...

Introduction: Tanacetum sonbolii (Asteraceae) is an endemic species in Iran. In the present study, we examined the effects of Tanacetum sonbolii hydroalcoholic extract on the formalin test in mice. Methods: 126 Swiss albino mice weighing 230-280g were used as subjects. The formalin test was performed on two control groups (marked as intact and saline groups n = 6 in each group) and an experimen...

Examination of type species of Calisius pallipes Stål 1860 from Brazil and Calisius ghiliani (A.Costa 1864) from Europe has revealed essential morphological differences warranting their placement into different genera. Stål's pallipes is the genotype of Calisius, and ghiliani that of Aradosyrtis A.Costa, whose generic status is revived. A neotype is designated for Aradosyrtis ghiliani A.Costa 1...

Objective: To explore whether Rhaponticum uniflorum (R. uniflorum) had anti-tumor effects in oral cancer and investigate the molecular mechanisms involved in these anti-tumor effects. Methods: Chemical compositions of R. uniflorum ethyl acetate (RUEA) extracts were detected by ultra-performance liquid chromatography-Q/time-of-flight mass spectrometry (UPLC-Q/TOF-MS), followed by pharmacology-ba...

The stereospecificity of the oxidation of trans-hex-2-en-l-01 and ethanol was determined for alcohol oxidases from Tanacetum vulgare leaves and from the yeast Candida boidinii. It was found that both enzymes remove the pro-1R hydrogen. The enzyme from Candida boidinii also removes the pro-1S hydrogen but t!o a much lesser degree.

The natural pyrethrins from the daisy-like flower, Tanacetum or Chrysanthemum cinerariifolium, are nonpersistent insecticides of low toxicity to mammals. Synthetic analogs or pyrethroids, evolved from the natural compounds by successive isosteric modifications, are more potent and stable and are the newest important class of crop protection chemicals. They retain many of the favorable propertie...
