A preparation for administering isotope-labelled urea together with acid in a solid form that is influenced by activity of Helicobacter pylori in the stomach only, avoiding any non-Helicobacter (unspecific) urease activity in the oral cavity and the pharynx. The preparation dissolves very quickly in the stomach. The preparation is used to show increased urease activity in the stomach in association with an ongoing Helicobacter pylori infection.

A peritoneal-based artificial kidney processes peritoneal fluid without need for additional fluids. Spent dialysate is separated into a protein-rich stream and a protein-free stream. The protein-rich stream is regenerated using a sorbent assembly, and its protein composition can be modified by removal of selected protein(s). Alternatively, the spent dialysate is first processed in a sorbent assembly and then separated into the protein-rich and protein-free streams. Immobilization of urease allows more protein rich fluid to be regenerated and re-circulated into the peritoneal cavity for toxin removal and allows practicable development of portable and wearable artificial kidneys.
