breast cancer is the second main cause of death among women. the use of medicinal plants has been common in many countries since ancient times. the aim of this study was to evaluate the antioxidant and anti-proliferative potential of achillea millefolium l. the antioxidant activity of the aqueous and hydroalcoholic extracts of achillea millefolium l. leaf and flower was measured by dpph and fra...

background: the aim of this study was to investigate the effect of methanolic extract of achillea millefolium l. (mea) on the antiproliferative activity of bleomycin on human prostate cancer and normal skin cells. materials and methods: human prostate cancer cell (du-145) and human non-malignant fibroblast cell (hfff2) were treated with mea at various concentrations ( 20, 100, 500, 1000 and 200...

there is substantial diversity in achillea biebersteinii plants in iran. it has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. research improvement for medicinal plants depends on the available genetic diversity. the assessment of genetic variability could increase the information for breeding programs. ...

the tenacity of a graph g, t(g), is dened by t(g) = min{[|s|+τ(g-s)]/[ω(g-s)]}, where the minimum is taken over all vertex cutsets s of g. we dene τ(g - s) to be the number of the vertices in the largest component of the graph g - s, and ω(g - s) be the number of components of g - s.in this paper a lower bound for the tenacity t(g) of a graph with genus γ(g) is obtained using the graph's...
