Abstract: Provided are an ionomer composition including silica particles which satisfy a specific equation and are acidic in an aqueous solution state and an ionomer film produced therefrom. The ionomer composition has excellent miscibility, and when a film is produced using the composition, surface appearance such as transparency is well-improved, and wear resistance, coefficient of friction, and the like of the film are significantly improved.

Abstract: The present disclosure relates to an ionomer composition containing a masterbatch and a glass laminate produced using the same. The masterbatch may be obtained by melt-kneading a zinc ionomer and a coupling agent, such that a crosslinking side reaction, which has been a problem in the related art, may be effectively suppressed, and as a result, an ionomer composition and a glass laminate that have significantly improved transparency, processability, and an adhesive strength to glass may be produced.

Abstract: Proposed is an all-solid-state battery including a self-standing sheet layer positioned on a negative electrode current collector. The all-solid-state battery may include the negative electrode current collector, the self-standing sheet layer positioned on the negative electrode current collector, a solid electrolyte layer positioned on the sheet layer, a positive electrode active material layer positioned on the solid electrolyte layer, and a positive electrode current collector positioned on the positive electrode active material layer. The sheet layer contains carbon nanotubes.

Abstract: A recombinant lentiviral vector includes a gene encoding a hepatocyte growth factor (HGF) protein. And a cell that is transfected with the lentivirus produced by using the vector is provided. The recombinant lentivirus includes a gene encoding a HGF protein, and a host cell transfected with the lentivirus maintains a high cell proliferation rate. Thus, a mesenchymal stem cell expressing HGF by being transfected with the lentivirus may be usefully employed as a cell therapeutic agent.

Abstract: A recombinant lentiviral vector containing a gene encoding a TRAIL protein and a CD protein; and a cell that is transfected with the lentivirus produced by using the vector. A host cell transfected with the recombinant lentivirus maintains a high cell proliferation rate and overexpresses a TRAIL protein and a CD protein. Thus, a mesenchymal stem cell transfected with the lentivirus may be usefully employed as a cell therapeutic agent.

Abstract: The present invention relates to a method for preparation of an immortalized stem cell line that has an immortalizing gene introduced thereinto and retains an expression potential of the introduced gene while being restrained from proliferation so that the immortalized stem cell line can be used as a cell therapeutic agent, and to a use thereof. The immortalized stem cell line of the present invention, which has undergone a radiation process, cannot proliferate while maintaining the expression of the introduced foreign protein at a certain level or higher and as such, can be advantageously used as clinical samples such as various cell therapeutic agents.

Abstract: The present invention relates to; a recombinant lentivirus comprising a gene encoding brain-derived neurotrophic factor (BDNF) protein; and a mesenchymal stem cell transformed with the lentivirus; and a method for mass-producing a cell therapeutic agent expressing BDNF protein using the same. The mesenchymal stem cell transformed with the recombinant lentivirus of the present invention can regulate the timing of expression of BDNF protein, maintain a high cell proliferation rate and overexpress a BDNF protein, and are excellent in safety. Therefore, a mesenchymal stem cells transfected with the lentivirus may be used for the treatment of various neurological diseases as a stein cell therapeutic agent capable of being mass-produced and maintaining the same effect.
