Natural grassland productivity, which is based on an individual plant's aboveground biomass (AB) and its interaction with herbivores, can obviously affect terrestrial ecosystem services and the grassland's agricultural production. As plant traits have been linked to both AB and ecosystem success, they may provide a useful approach to understand the changes(More)
Sheepgrass [Leymus chinensis (Trin.) Tzvel] is a valuble forage plant highly significant to regional grassland productivity of Euro-Asia steppes. Although effects of environmental stress including drought have been studied, impact of nutrient deficiency in particular phosphate (Pi), one of the essential macronutrient, is not reported. Here, we investigated(More)
BACKGROUND Topoisomerase 2 alpha (TOP2A) is a key enzyme in DNA replication and a target of various cytotoxic agents including anthracyclines. Previous studies evaluating the predictive and prognostic values of TOP2A in breast cancer are contradictory, likely secondary to the use of both different detection methods and different cutoff thresholds for(More)
