Abstract:
PURPOSE: A bone cement composition is provided to secure biocompatible stiffness instead of overly high stiffness. CONSTITUTION: A bone cement composition includes: a powder part containing silk fibroin hydrolysate powder, polyacrylo-nitrile PMMA, and polymerization initiator; and a fluid part containing acrylic monomer, polymerization accelerator, and polymer inhibitor. The powder part and fluid part are mixed with each other. The silk fibroin hydrolysate powder has molecular weight 0.1-100 kDa.
Abstract:
PURPOSE: A bone graft material is provided to rapidly regenerate a damaged and lost part of bone by applying the bone graft material to the damaged and lost part of bone. CONSTITUTION: A bone graft material includes silk fibroin peptide as an active ingredient. The silk fibroin peptide has average molecular weight of 100-4,000 Da and is prepared by removing sericin by treating silk with alkaline solution and hydrolyzing the silk with acid. The silk fibroin peptide improves the expression of alkaline phosphatase, collagen type I-alpha 1, fibronectin, or transforming growth factor(TGF)-beta 1.
Abstract:
PURPOSE: An AMP-activated protein kinase fusion protein is provided to suppress inflammation by intracellular concentration-dependent and time-dependent introduction. CONSTITUTION: A cell permeable AMP-activated protein kinase fusion protein has a protein transport domain which is bound to at least one terminal of the AMP-activated protein kinase. The protein transport domain is PEP-1 peptide. The AMP-activated protein kinase has an amino acid of sequence number 7. A cosmetic composition contains the AMP-activated protein kinase as an active ingredient. A pharmaceutical composition for treating inflammation including type 2 diabetes, obesity, skin cancer, and atopic inflammation contains the AMP-activated protein kinase as an active ingredient and pharmaceutically acceptable carrier.
Abstract:
PURPOSE: A silk/hydroxyapatite complex nanofiber supporter for osteanagenesis is provided to promote a cell growth promotion effect and to remove cytotoxin. CONSTITUTION: A silk/hydroxyapatite complex nanofiber supporter for osteanagenesis constituted as follows. In the nanofiber supporter, hydroxyapatite is coated on the surface thereof and silk nanofiber having the diameter of tens or hundreds nanometers is three-dimensionally arranged. The silk nanofiber maintains the form of a strand of fiber without conglomeration or entanglement thereof.
Abstract:
PURPOSE: Provided are a nucleotide sequence of cDNA coding protein disulfide isomerase(PDI) isolated from the cultured cell of a silkworm, and an amino acid sequence thereof, thereby increasing the expression of useful proteins and consequently mass-producing them economically. CONSTITUTION: The nucleotide sequence of cDNA coding protein disulfide isomerase(PDI) isolated from the cultured cell of a silkworm, is represented by the SEQ ID NO:1, and its amino acid sequence is represented by the SEQ ID NO:2.
