A method of promoting increased cellular hydration in a multicellular organism that is capable of intracellular water permeation includes the step of causing the multicellular organism to ingest an aqueous solution that contains an amount of a carbohydrate clathrate component. There is also a step of enhancing the intracellular permeation. The multicellular organism contains aquaporins, and the causing step involves interaction of the composition with the aquaporins. The cellular hydration promoted and caused by the method is corroborated by a test that uses human-aquaporin-expressed frog oocytes. The test uses single cell Xenopus laevis frog oocytes having expressed human aquaporin AGP1 water channels. There is also a beverage composition that increases lifespan in the multicellular organism, and a beverage composition that promotes cellular hydration when ingested by a multicellular organism.

The invention provides injectable, tough hydrogels that can be crosslinked in situ on demand using minimally-invasive methods, such as visible light exposure is an unmet medical challenge. Among the emerging biopolymers for tissue sealing, gelatin methacryloyl (GelMA), a naturally-derived biopolymer obtained from denatured collagen, has secured a promising role as a result of its excellent bioadhesion, biodegradation, and biocompatibility. To overcome one of the main shortcomings of GelMA, i.e., brittleness, we hybridized it using methacrylate-modified alginate (AlgMA) to impart ion-induced reversible crosslinking that can dissipate energy under strain. The hybrid GelMA-AlgMA hydrogels provide a photocrosslinkable, injectable, and adhesive platform with an excellent toughness that can be engineered using divalent cations, such as calcium. This class of novel hybrid biopolymers with more than 600% improved toughness may set the stage for durable, mechanically-resilient, and cost-effective tissue sealants in minimally invasive procedure, especially for stretchable tissues.
