The essential oils obtained by hydrodistillation (HD), steam distillation (SD) and solvent free microwave extraction (SFME) from the stems and flowers of Tanacetum tenuisectum (Boiss.) Podl., which is endemic to Iran,were analyzed by GC and GC/MS.Camphor (26.9 %, 27.2% and 25.5%), borneol (12.6%, 11.5% and 7.6%) and 1, 8-cineole (7.9%, 13.2% and 11.3%) were the main constituents of the HD, SD a...

We investigated whether parthenolide, the principal bioactive component of the herb feverfew (Tanacetum parthenium) induced apoptosis in pre-B acute lymphoblastic leukemia (ALL) lines, including cells carrying the t(4;11)(q21;q23) chromosomal translocation. Parthenolide induced rapid apoptotic cell death distinguished by loss of nuclear DNA, externalization of cell membrane phosphatidylserine, ...

Tanacetum argenteum (Lam.) Willd. subsp. flabellifolium (Boiss. & Heldr.) Grierson of Asteraceae is an endemic species in Turkey. Hydrodistillation of aerial parts using a Clevenger apparatus yielded an essential oil, which was subsequently analyzed by gas chromatography-mass spectroscopy (GC-MS). alpha-Pinene (29%), (E)-sesquilavandulol (16%), and camphor (14%) were found as main constituents....

Mature larva and pupa of Adosomus (s. str.) roridus (Pallas, 1781) (Curculionidae: Lixinae: Cleonini) are described and compared with ten other taxa of Cleonini with known larvae. This weevil is an oligophagous species on the Asteraceae family. From our observations in Slovakia, we found active adults from April to September in dry sunny places within extensively used or fallow vineyards and in...

BACKGROUND Art v 1, Amb a 4, and Par h 1 are allergenic defensin-polyproline-linked proteins present in mugwort, ragweed, and feverfew pollen, respectively. We aimed to investigate the physicochemical and immunological features underlying the different allergenic capacities of those allergens. METHODS Recombinant defensin-polyproline-linked proteins were expressed in E. coli and physicochemic...
