OBJECTIVES This study was performed to determine the lethal and the inhibitory effects of ethanol extracts of Achillea millefolium (A. millefolium) and Hypericum perforatum (H. perforatum) on Toxoplasma gondii (T. gondii) RH strain tachyzoites in vitro. METHODS The tachyzoites were treated with concentrations of 10, 50, and 100 mg/mL of A. millefolium and H. perforatum extracts within 10, 30,...

Oleander is very frequently planted as an ornamental shrub in urban areas of the Mediterranean. Its most common pest aphid Aphis nerii, and heavy infestations produce aesthetic damage disturbances to citizens, they are sprayed with insecticides order reduce population density. One alternative method conservation biological control which enhanced by provisioning food, refuges, reproduction sites...

The objective of this study was to evaluate the biological activities and chemical fingerprint profiles extracts obtained from twelve Achillea L. species (A. lycaonica, A. biebersteinii (syn: arabica), kotschyi subsp. kotschyi, schischkinii, millefolium millefolium, sintenisii, setacea, teretifolia, wilhelmsii santolinoides wilhelmsii), nobilis, goniocephala, spinulifolia). antioxidant, enzyme ...

The radioprotective effect of Achillea millefolium L (ACM) extract was investigated against genotoxicity induced by ionizing radiation (IR) in human lymphocytes. Peripheral blood samples were collected from human volunteers and incubated with the methanolic extract of ACM at different concentrations (10, 50, 100, and 200 μg/mL) for 2 hours. At each dose point, the whole blood was exposed in vit...

The relationship between respiratory alternative pathway and carbohydrate status was studied in mature leaves of three native representatives of forest and meadow communities of north-east Russia – Ajuga reptans L., Achillea millefolium L. and Calla palustris L. All experiments were carried out on plants growing in natural habitats. The activity of the alternative respiratory pathway was studie...

The evolution of increased competitive ability (EICA) hypothesis predicts that escape from intense herbivore damage may enable invasive plants to evolve higher competitive ability in the invasive range. Below-ground root herbivory can have a strong impact on plant performance, and invasive plants often compete with multiple species simultaneously, but experimental approaches in which EICA predi...
