1-(2-chlorophenyl) ethanol (CpE) is of health and environmental concern due to its toxicity and its use as an inter-mediate in pharmaceutical manufacturing. The current work deals with the catalytic reductive dechlorination and detoxification of CpE by pd/Fe bimetal. CpE was effectively dechlorinated to 1-phenyl ethanol (pE) accompanied by the equivalent release of chloride. The extent of CpE dechlorination increased with temperature,Fe dosage and pd loading. A decrease in solution pH increased CpE dechlorination,resulting presumably from an increase in hydrogen production. Under the specific conditions of 20 g/L pd/Fe,0.10% pd (w/w) and initial pH 5-6,the CpE dechlorination was completed within 145 min. The dechlorination fol-lowed a pseudo-first-order kinetics with an activation energy of 56.7 kJ/mol. The results of toxicity testing showed that CpE was very toxic to Chlorella,whereas pE showed little toxicity. The toxicity of the reaction solution declined gradually and the pro-moting effects on Chlorella intensified consequently with the dechlorination process. Thus,the reductive dechlorination of CpE to pE by pd/Fe was a detoxification process. It may be used to effectively reduce the toxicological effects of CpE-contaminated wastewater,thereby enhancing the performance of subsequent biological processes in wastewater treatment.

In spite of the development of new treatments for late stage prostate cancer, significant challenges persist to match individuals with effective targeted therapies. Genomic classification using high-throughput sequencing technologies has the potential to achieve this goal and make precision medicine a reality in the management of men with castrate-resistant prostate cancer. This chapter reviews some of the most recent studies that have resulted in significant progress in determining the landscape of somatic genomic alterations in this cohort and, more importantly, have provided clinically actionable information that could guide treatment decisions. This chapter reviews the current understanding of common alterations such as alterations of the androgen receptor and pTEN pathway, as well as ETS gene fusions and the growing importance of pARp inhibition. It also reviews recent studies that characterize the evolution to neuroendocrine tumors, which is becoming an increasingly important clinical problem. Finally, this chapter reviews recent innovative studies that characterize the compelling evolutionary history of lethal prostate cancer evidenced by polyclonal seeding and interclonal cooperation between metastasis and the importance of tumor clone dynamics measured serially in response to treatment. The genomic landscape of late stage prostate cancer is becoming better defined, and the prospect for assigning clinically actionable data to inform rationale treatment for individuals with this disease is becoming a reality.
