After I plotted a few points on a piece of paper at home, I started to realize that there...

ii To my parents iii Acknowledgement I entered the Ph.D. program five years ago certain that I wanted to do research in communication and equally certain that I did not want to do anything related to control. I finish my Ph.D. uncertain about the distinction between control and communication and wondering why they are taught separately. I would like to express my sincerely gratitude to my advis...

Background: This study aimed to examine the composition of essential oil (EO) of A. millefolium aerial parts wild plant grown in France and evaluate its antioxidant, antibacterial, and antifungal activities. Methods: GC-MS was used to identify the chemical composition of EO. Antioxidant activity (AA) of EO was evaluated by Oxipres method. Antimicrobial activity of EO was evaluated by Agar-well ...

Turkish yarrow (Achillea gypsicola Hub. Mor.) contains medicinally valuable bioactive metabolites. Light plays a key role in many physiological events plants such as the accumulation of phenylpropanoid metabolites, particularly photosynthesis. The aim this study was to determine effects light on biosynthesis metabolites and biomass growth cell suspension cultures. In vitro plantlets obtained fr...

Achillea tenuifolia Lam. (Asteraceae) afforded a methanolic extract from which after fractionation in solvents with different polarities, two known flavones 3', 5- dihydroxy- 4', 6, 7- trimethoxy flavone (eupatorine, compound 3), 5- hydroxy- 3',4', 6, 7- tetramethoxyflavone (compound 4), besides stearic acid (compound 1), lupeol (compound 2), daucosterol (β- sitosterol 3-O- β- D- glucopyranosid...

OBJECTIVE Achillea millefolium (A. millefolium) is known as an orexigenic herb in Iranian traditional medicine. In this study, the possible orexigenic effect of hydro-alcoholic extract of A. millefolium was investigated by measuring plasmaghrelin level. MATERIALS AND METHODS Thirty male Wistar rats were divided into five groups. Control group received water. Treatment groups received 50, 100 ...

The anti-inflammatory activity of Achillea and Ruscus extracts was studied in comparison with diclofenac sodium topical gel (diclosal Emulgel), using the carrageenan induced paw edema model in Albino rats. Gel formulation was prepared containing 6% of each extract in gel base, namely sodium carboxymethylcellulose (NaCMC). The kinetics of drug release from the prepared formulation was studied se...

Achillea wilhelmsii have been used in folk remedies. The relaxant effects of the extract of A. wilhelmsii on tracheal chains of guinea pigs were examined. The relaxant effects of four cumulative concentrations of the extract, theophylline and saline were examined by their relaxant effects on precontracted tracheal chains of guinea pig by KCl (group 1), 10 μM methacholine (group 2), incubated ti...
