Abstract Aggressive epithelial ovarian cancer (EOC) is genetically and epigenetically distinct from normal ovarian surface epithelial cells (OSE) and early neoplasia.Co-expression of epithelial and mesenchymal markers in EOC suggests an involvement of epithelial-mesenchymal transition (EMT) in cancer initiation and progression.This phenomenon is of
Soil seed banks are important to the maintenance and restoration of floras.Extant seed banks exhibit unique characteristics with regard to the distribution of seed size and seed density.Seeds were recovered from the Upper Pennsylvanian Wise Formation in southwest Virginia.Structurally preserved seeds were also examined from coal balls of the Pennsy
An investigation was carried out to understand the effects of Sn on hardness, wear Locking Cable rate and the coefficient of friction of spinodal Cu-Ni-Sn alloys.Alloys of appropriate compositions were melted in a crucible furnace under argon atmosphere and cast into sand moulds.Solution heat treated and aged specimens were tested for hardness, wea
