  • Publication number: 20250000807
    Abstract: The present disclosure provides a circCDK13-enriched engineered small extracellular vesicle (E-sEV), and a preparation method and use thereof, and belongs to the technical field of biomedicine. The present disclosure provides a preparation method of the circCDK13-enriched E-sEV. In the present disclosure, human placenta-derived mesenchymal stem cells (hP-MSCs) are infected with a vector overexpressing circCDK13, and a resulting cell supernatant is collected to obtain a small extracellular vesicle (sEV) overexpressing the circCDK13, which is used for wound healing in diabetes mellitus (DM). The E-sEV shows a therapeutic effect on DM wounds that is significantly better than that of natural small extracellular vesicles (N-sEVs) secreted by the hP-MSCs. This product not only exhibits advantages in healing speed, but also has a greater application potential in stimulating skin appendage regeneration and improving the quality of wound healing.

  • Patent number: 6755689
    Abstract: An electrical connector (1) includes a housing (10), four signal contacts (20), a pair of power contacts (30) and a shielding (40, 50). The housing has a forwardly extending mating tongue (12). The mating tongue defines four receiving channels (126) therein in a vertical direction and a pair of side surface (122). A groove (128) is defined in each of the side surfaces of the mating tongue. Each signal contact comprises a mating portion (21) retained in a corresponding receiving channel. Each power contact comprises a mating portion (31) retained in a corresponding groove of the mating tongue. The shielding substantially surrounds the housing. The connector has a small dimension and can be used in a portable electronic device.
