Urea is highly concentrated in the mammalian kidney to produce the osmotic gradient necessary for water re-absorption. Free diffusion of urea across cell membranes is slow owing to its high ...

Most interestingly, in the structure the CT domain interacts with the BCCP domain, with biotin and a urea molecule bound at its active site. This structural information and our follow-up biochemical ...

Chronic gastric infection with Helicobacter pylori affects ~50% of the global population and is the leading cause for peptic ulcer disease and stomach cancer 1. Survival of H. pylori in acidic ...

“This suggests that the MXene structure could potentially be fine-tuned to absorb urea by optimizing the chemical composition and interlaminar distance of the material.” In addition to this physical ...
