摘要:
A method of manufacturing ceramics includes: placing, on a base material, a first slurry in which a metal oxide powder is dispersed; applying a magnetic field to the first slurry to solidify the first slurry, thereby forming an under coat layer made of a first compact; placing, on the under coat layer, a second slurry containing a metal oxide powder constituting the ceramics; applying a magnetic field to the second slurry to solidify the second slurry, thereby forming a second compact to obtain a laminated body of the second compact and the under coat layer; and obtaining the ceramics made of the second compact by removing the under coat layer from the laminated body of the second compact and the under coat layer and then sintering the second compact, or sintering the laminated body of the second compact and the under coat layer and then removing the under coat layer.

摘要:
Disclosed are compositions comprising the platelet activation receptor C-type Lectin- like Receptor 2 (CLEC-2), and compositions comprising anti-CLEC-2 antibodies or antibodies that inhibit the interaction of CLEC-2 with podoplanin. Also disclosed are and methods of treating subjects in need thereof, comprising administering to the subject an effective amount of the disclosed compositions. Disclosed are recombinant CLEC-2 polypeptides, nucleic acids, antibodies, and compositions comprising recombinant CLEC-2 polypeptides, nucleic acids and antibodies. CLEC-2, has been found to interact with podoplanin. Recombinant CLEC-2 inhibits platelet aggregation induced by podoplanin- expressing tumor cells or lymphatic endothelial cells. Thus, CLEC-2 is responsible for platelet aggregation induced by endogenously expressed podoplanin on cell surfaces. CLEC- 2 is therefore a physiological target protein of podoplanin and is involved in podoplanin- induced platelet aggregation, tumor metastasis, and other cellular responses related to podoplanin. Disclosed are methods of treating, for instance, platelet aggregation-related disorders by administering effective amounts of the disclosed compositions to subjects in need thereof.
