Effective Removal of Clenbuterol and Ractopamine from Water with a Stable Al(III)-Based Metal-Organic Framework.

Clenbuterol (CLE) and ractopamine (RAC) are two kinds of typical β-adrenergic agonists which pose a serious threat to the health of human beings. In this work, 10 kinds of metal-organic frameworks (MOFs) with high stability and various pore features are screened to assess adsorption performance for CLE and RAC. An Al(III)-MOF (BUT-19) with abundant ethyl groups exhibits exceptional performance in removing CLE and RAC from water.

Analysis of the factors influencing the survival time of patients with sarcomatoid renal cell carcinoma.

The aim of the present study was to identify the factors influencing the survival time of patients with sarcomatoid renal cell carcinoma (SRCC). Between January 2000 and September 2017, a total of 21 patients were enrolled, all of whom were diagnosed with SRCC. In total, eight prognostic factors were analyzed using the Kaplan-Meier estimator, a log-rank test and Cox's proportional hazards model.
