Dietary nitrate maintains intestinal epithelia homeostasis in aged mice.

The intestinal tract, which is the primary site of digestion and absorption of nutrients, is one of the most vulnerable organs during aging. Dietary nitrate, which is mainly derived from the diet and absorbed in the intestinal tract, is a key messenger that connecting oral and general health. However, whether dietary nitrate regulates intestinal tract homeostasis remains unclear.

Gel Formed by Self-Assembly of a Urea-Modified Monopyrrolotetrathiafulvalene Derivative Displays Multi-Stimuli Responsiveness and Absorption of Rhodamine B.

A new monopyrrolotetrathiafulvalene-based derivative containing a urea group was designed, synthesized and thoroughly characterized. It proved to be a non-gelator in a single solvent even when heated or sonicated. However, it could self-assemble in a CHCl (CH Cl )/n-hexane mixture to form a thermo-responsive supramolecular organogel.
