Global levels of reactive nitrogen are predicted to rise in the coming decades as a result of increased deposition from the burning of fossil fuels and the large-scale conversion of nitrogen into a useable form for agriculture. Many plant communities respond strongly to increases in soil nitrogen, particularly in northern ecosystems where nitrogen levels are naturally very low. An experiment in...

Different pharmacological effects of Achillea millefolium including its relaxant effect on smooth muscle have been shown previously. In the present study the stimulatory effect of the plant extract on β-adrenoceptor of tracheal muscle was examined in order to investigate one possible mechanism for its observed relaxant effect. Effect of three concentrations of hydroethanol extract, 10 nM propra...

Miracles have been a perennial source of interest to medieval historians, and in recent years the level of interest has only increased as scholars from a growing range of disciplines have discovered the value of miracle stories as a source for their studies. This diversity of interest is reflected in this volume (developed from a conference held in Cambridge in 2011), which includes historical,...

Skin wound healing especially when it occurs on the face or somewhere important for cosmetic reasons, is very significant physiological procedure. It is quite obvious that promoting this healing is important too. In this study we tried to compare the effects of Achillea millefolium and Zinc oxide on secondary intentioned open-wound healing in rats. Zinc oxide is being used worldwide as an absor...

Two new aphid species of the nominotypical subgenus genus Macrosiphoniella (Aphidinae) are described from Kazakhstan. Both inhabits yarrow (Achillea millefolium L.). kazakhstanica sp. n. most similar to M. silvestrii Roberti, 1954 but differs latter in number secondary rhinaria apterous and alate viviparous females (5–10 24–26 vs 14–25 48–68), proportion processus terminalis base VI antennal se...
