20140083945 | Reducing Soluble Urokinase Receptor in the Circulation - Focal segmental glomerulosclerosis (FSGS) is a common cause of proteinuric kidney disease, which comprises both native and transplanted kidneys.

Higher pre-transplantation suPAR levels are associated with risk for FSGS recurrence in kidney grafts. Renal disease only develops when suPAR sufficiently activates podocyte β3 integrin. Thus, disease pathogenesis can be stopped or slowed by ex vivo removal of suPAR from a subject's circulation. Removal may be measured by comparing the level (e.g., amount or concentration) of suPAR before and after such treatment. | 03-27-2014 |

20140299546 | NANOFILTRATION PROCESS FOR ENHANCED BRINE RECOVERY AND SULFATE REMOVAL - In a nanofiltration system for removing sulfate impurity from an aqueous brine stream and for recovering the brine, introducing a dilution stream upstream of the feed stream inlet of a nanofiltration module in the system dilutes the feed stream. This increases the amount of brine salt and water obtained in the permeate stream without substantially diluting the concentration of sulfate in the pass stream and hence results in enhanced recovery of brine while efficiently removing sulfate impurity. The system and process is especially suitable for recovering brine and removing sulfate impurity from a brine stream in a brine electrolysis plant. In a conventional system, the heat exchanger typically used to cool the feed stream can be omitted if the dilution stream is provided at a temperature suitably lower than that of the feed stream. | 10-09-2014 |
