Abstract: Disclosed is a system and a method for information distribution. The system comprises: a server for generating a group key and its corresponding key deriving parameter, wherein the server encrypts sensitive contents by using the group key to obtain encrypted information; and terminals configured to receive the encrypted information through an open channel, extract the group key, then decrypt the encrypted information by using the group key to obtain the original content. In the group forming process, each terminal encrypts its private identifier using the public key and submits the ciphertext to the server. In information distribution process, the server transmits the ciphertext of sensitive contents and the key deriving parameter to the terminals via open channel Because private information available only to respective group members is required for calculating the group key, this mechanism ensures that the sensitive content can be transmitted securely on the open channel.

Abstract: A therapeutic microporous hydrogel scaffold for use in an animal is disclosed that releases one or more therapeutic agents or drugs. The scaffold uses a drug-releasing microporous annealed particle system that encapsulates drug-loaded nanoparticles into particle building blocks. By modulating nanoparticle hydrophilicity and pre-gel solution viscosity, the particle building blocks were generated with consistent and homogeneous encapsulation of nanoparticles. The scaffold may be used to treat myocardial infarction (MI) using, for example, the drugs forskolin (F) and Repsox (R). The intramyocardial injection of the pre-annealed hydrogel slurry of particles that formed the resultant scaffold improved left ventricular functions, which were further enhanced with increased angiogenesis and reduced fibrosis and inflammatory response.

Abstract: We have discovered a chemical cocktail that selectively induces a robust expansion of myogenic stem cells from readily-obtainable dermal cells and from muscle stromal cells. By differential plating and lineage tracing, we show that Pax7+ cells were the major source for chemical-induced myogenic stem cells (CiMCs). We further performed single-cell RNA sequencing (scRNA-seq) analysis to characterize the transcriptomic profile of CiMCs and demonstrate a specific expansion of myogenic cells from heterogeneous dermal cell population. Upon transplantation into the injured muscle, CiMCs were efficiently engrafted and improved functional muscle regeneration in both adult and aged mice. Furthermore, an in situ therapeutic modality using this cocktail was developed by loading the chemical cocktail into injectable nanoparticles, which enabled a sustained release of the cocktail in injured muscle and a local expansion of resident satellite cells for muscle regeneration in adult and aged mice.
