  • Patent number: 11655512
    Abstract: Provided in the present application are a rare-earth microalloyed steel and a control process. The steel has a special microstructure, and the microstructure comprises a rare earth-rich nanocluster having a diameter of 1-50 nm. The nanocluster has the same crystal structure type as a matrix. The rare earth-rich nanocluster inhibits the segregation of the elements S, P and As on a grain boundary, and obviously improves the fatigue life of the steel. In addition, a rare-earth solid solution also directly affects a phase change dynamics process so that the diffusion-type phase change starting temperature in the steel changes at least to 2° C., and even changes to 40-60° C. in some kinds of steel, thereby greatly improving the mechanical properties thereof, and providing a foundation for the development of more kinds of high-performance steel.

  • Publication number: 20150258168
    Abstract: The present invention relates generally to the use of modulators of podoplanin (PDPN) mediated platelet activation. For example, an agonist or mimic of podoplanin (PDPN)/C-type lectin-like receptor 2 (CLEC-2) signaling may be used to inhibit vascular leakage or promote vascular integrity. Alternatively, an antagonist of podoplanin (PDPN)/C-type lectin-like receptor 2 (CLEC-2) signaling may be used to inhibit platelet activation.

  • Patent number: 8633021
    Abstract: A method of in vitro fucosylation of selectin ligands on cord blood-derived hematopoietic stem cells for bone marrow transplantation is disclosed. In this method, an effective amount of an ?1,3-fucosyltransferase, e.g., ?1,3-fucosyltransferase VI, is used in vitro to treat cord blood-derived hematopoietic stem cells to convert non-functional PSGL-1 or other ligands on the cell surface into functional forms that bind selectins, especially P-selectin or E-selectin. The treated cells have enhanced effectiveness in reconstituting bone marrow in patients in need of such therapy.
