Changes in Current Transport and Regulation of the Microstructure of Graphene/Polyimide Films under Joule Heating Treatment.

The excellent electrical properties of graphene have received widespread attention. However, the difficulty of electron transfer between layers still restricts the application of graphene composite materials to a large extent. Therefore, in this study, graphene/polyimide films were subjected to a Joule heating treatment to improve the electrical conductivity of the film by ~76.

Empagliflozin attenuates inflammation levels in autoimmune myocarditis through the STAT3 pathway and macrophage phenotype transformation.

Objective: To investigate the anti-inflammatory actions and molecular mechanisms of the sodium/glucose cotransporter 2 (SGLT-2) inhibitor empagliflozin on autoimmune myocarditis.

Methods: The experimental autoimmune myocarditis (EAM) mouse model was constructed using peptides, and the therapeutic effects of empagliflozin on cardiac inflammation and fibrosis were observed using hematoxylin and eosin (HE), Sirius red staining, and Masson's trichome staining. Western blotting was used to identify the actions of empagliflozin on the surface marker expression levels of M2 macrophages and inflammatory factors.

Cell Seeding Process Experiment and Simulation on Three-Dimensional Polyhedron and Cross-Link Design Scaffolds.

Cell attachment to a scaffold is a significant step toward successful tissue engineering. Cell seeding is the first stage of cell attachment, and its efficiency and distribution can affect the final biological performance of the scaffold. One of the contributing factors to maximize cell seeding efficiency and consequently cell attachment is the design of the scaffold.
