A thiol-functionalized zirconium metal-organic cage for the effective removal of Hg from aqueous solution.

The mercury ions in waste water have threatened public health and environmental protection. In this sense, novel materials with outstanding performances for removal of Hg are imperative. Herein, we demonstrate a thiol-functionalized zirconium metal-organic cage (MOC-(SH)) with excellent dispersion displays ideal properties for Hg capture.

Stem cell-like circulating tumor cells indicate poor prognosis in gastric cancer.

Circulating tumor cells (CTCs), which have stem cell-like characteristics, might play a crucial role in cancer metastasis. CD44 has been identified as gastric cancer (GC) stem cell (CSC) marker. Here, the prognostic significance of CD44-positive CTCs in GC patients was investigated.
