Abstract: A method for chromium removal from post-tanning wastewater includes the following steps: (a) mixing pretreated post-tanning wastewater with an induction reagent to allow an induction reaction; and (b) adjusting a pH of a mixture obtained after the induction reaction to higher than 7.0 for precipitation; where the induction reagent includes a soluble metal salt. In the treatment method of the present disclosure, pretreated post-tanning wastewater is mixed with an induction reagent, a small amount of neutral chromium complexes remaining in the wastewater are converted into cationic chromium complexes under the action of the induction reagent (that is, a charge property of the chromium complex is changed), and then a pH is adjusted for precipitation to remove chromium, which greatly improves the removal efficiency of chromium in wastewater.

Abstract: A BMP2 surrogate protein is provided comprising two different antigen binding regions (ABR), which can be configured as immunoglobulin “single variable domains” (ISV). A first ISV specifically binds to a first BMP2 receptor, e.g. BMPR1a; and a second ISV specifically binds to a second BMP2 receptor, e.g. BMPR2. In some embodiments the first and second ISV are joined by a cleavable linker that is susceptible to proteases selectively expressed in monocytic cells or macrophages, relative to skeletal stem cells.

Abstract: Provided are innovative compositions for tethering blocking an inactivating of airborne respiratory infectious viruses. The compositions comprise bispecific proteins with two different antigen binding regions (ABR), which are typically configured as immunoglobulin “single variable domains” (ISV). A first ISV binds to a surface protein found on an airborne infectious virus. A second ISV binds to a mucin protein, e.g. a mucin protein present on ocular, nasopharyngeal, tracheal and/or oral surfaces of a mammal. The two ISV are joined by a polypeptide linker.
