Herein, for the first time, a system of ultrasound-treated CoS2-x mixed with Fe2+ is constructed to sustainably release singlet oxygen (1 O2 ) for the effective degradation of various organic pollutants, including dyes, phenols, and antibiotics. Ultrasonic treatment produces defects on the surface of CoS2 which promote the production of ROSs and the circulation of Fe3+ /Fe2+ . With the help of Co4+ /Co3+ exposed on the surface of CoS2-x , the directional conversion of superoxide radical (. O2- ) to 1 O2 is realized. The CoS2-x /Fe2+ system can degrade organic pollutants efficiently for up to 30 days, which is significantly better than the currently recognized CuPx system ( less then 3 days). Therefore, CoS2-x provides a new choice for the long-term remediation of organic pollutants in controlling large area river pollution.PBX1 encodes the pre-B cell leukemia homeobox transcription factor, a three amino acid loop extension (TALE) homeodomain transcription factor, which forms nuclear complexes with other TALE class homeodomain proteins that ultimately regulate target genes controlling organ patterning during embryogenesis. Heterozygous de novo pathogenic variants in PBX1 resulting in haploinsufficiency are associated with congenital anomalies of the kidneys and urinary tract, most commonly renal hypoplasia, as well as anomalies involving the external ear, branchial arch, heart, and genitalia, and they cause intellectual disability and developmental delay. Affected individuals described thus far have had de novo variants. Here, we report three related individuals with an inherited pathogenic intragenic PBX1 deletion with variable clinical features typical for this syndrome.Melatonin, a molecule first discovered in animal tissues, plays an important role in multiple
