Peritoneal dialysis (PD) solutions can produce changes in the peritoneal membrane and structure which are related to the high glucose concentrations and low pH of these solutions. This study was designed to examine the effects of high glucose (76-214 mM) and low pH (5.3) solutions on human peritoneal mesothelial cells in culture. Changes in mesothelial cell biosynthesis and cell numbers were evident within 2 hours of exposure to unmodified dialysis solutions. In the development of new dialysis solutions, human peritoneal mesothelial cells in culture provide a good in vitro model to determine potential toxicity.

Advancements in xenotransplantation intersecting with modern machine perfusion technology offer promising solutions to patients with liver failure providing a valuable bridge to transplantation and extending graft viability beyond current limitations. Patients facing acute or acute chronic liver failure, post-hepatectomy liver failure, or fulminant hepatic failure often require urgent liver transplants which are severely limited by organ shortage, emphasizing the importance of effective bridging approaches. Machine perfusion is now increasingly used to test and use genetically engineered porcine livers in translational studies, addressing the limitations and costs of non-human primate models.

MXenes, a family of two-dimensional transition metal carbides and nitrides, exhibit exceptional properties such as high electrical conductivity, large surface area, and chemical versatility, making them ideal candidates for various dialysis applications. One prominent application of MXenes lies in the efficient removal of toxic metals and harmful dyes from wastewater. Their unique structure allows for rapid adsorption and selective separation, significantly improving purification processes.

Copper-containing industrial wastewater, characterized by strong acidity, high ionic strength, and various competing metals, presents significant challenges for Cu(II) recovery. To address these issues, an electric field-enhanced ultrafiltration process was developed, assisted with a functional polyelectrolyte with high selectivity for Cu(II). The polyelectrolyte, termed PPEI, was synthesized by grafting picolyl groups onto polyethyleneimine (PEI), enhancing its affinity for Cu(II).

Rationale & Objective: Peritoneal dialysis (PD) solutions provide both clearance of uremic toxins and sodium and water. An intraperitoneal (IP) solution of icodextrin and glucose designed without the requirement for uremic toxin clearance could provide substantially greater sodium and water removal than PD solutions.
Study Design: We examined varying concentrations of icodextrin and dextrose IP solutions in rats.

Baclofen is a gamma-aminobutyric acid agonist that is commonly and widely used for the treatment of muscle spasticity. Given its predominant kidney excretion, patients with reduced kidney function are at particular risk of drug accumulation and toxicity, with neurotoxicity in the form of drowsiness, encephalopathy, seizures, and coma being the most reported clinical features. In addition to the importance of early identification of baclofen toxicity and drug discontinuation, dialysis can effectively accelerate baclofen elimination given its small molecule weight, and the relatively low volume of distribution and weak protein binding.
