Abstract:
The present invention relates to a method for manufacturing a multi-functional bio-material conjugate, and a multi-functional bio-material conjugate manufactured by means of same, and more specifically, to a method for manufacturing a multi-functional bio-material conjugate used as a biosensor for detecting microorganisms or similar, and a multi-functional bio-material conjugate manufactured by means of same. The method for manufacturing a multi-functional bio-material conjugate comprises: (a) a step for coating protein on a first nano particle having magnetic or fluorescent characteristics; (b) a step for manufacturing a conjugate by adhering a second nano particle having metallic characteristics on the first nano particle, coated with protein; and (c) a step for manufacturing a multi-functional bio-material conjugate by adhering bio-material to the conjugate. By using two kinds of particle, the method for manufacturing a multi-functional bio-material conjugate according to the present invention prevents the precipitation of nano particles, enables bio-material to be easily fixed, and enables the manufacture of a bio-material conjugate having multiple functions. In addition, the multi-functional bio-material conjugate manufactured via said method can be used to detect microorganisms, up to a concentration of 101 cfu.

The composition according to the present invention has the effects of suppressing VEGF expression, reducing tumor cells, reducing MMP-9, and inhibiting oxygen free radicals, among others, thereby having excellent anticancer and antioxidant effects and accelerating treatment when administrated in combination with an anticancer therapeutic agent.
Abstract:
The present invention relates to a pharmaceutical composition containing jetbead extracts as active ingredients for preventing or treating Parkinson's disease, wherein the jetbead extracts are obtained by performing extraction on the stem of the jetbead using an organic solvent. The present invention also relates to food additives which contain jetbead extracts as active ingredients and which exhibit the effects of preventing or treating Parkinson's disease. The jetbead extracts of the present invention may prevent or treat Parkinson's disease without producing any particular side effects, and therefore can be widely used for more safely treating Parkinson's disease.
Abstract:
The present invention relates to a lactic acid bacteria-derived glycoside hydrolase, specifically to a glycoside hydrolase derived from Weissella confuse, Pediococcus pentosaceus, Leuconostoc citreum or Leuconostoc mesenteroides subsp. mesenteroides, and uses thereof.
Abstract:
The present invention relates to a pharmaceutical composition for preventing or treating asthma containing maackiain as an active ingredient. The maackiain of the present invention can be used to advantage as a composition for preventing, treating and alleviating asthma because it has an outstanding effect in suppressing the production of ovalbumin and in particular IgE in serum and bronchoalveolar lavage fluid and in suppressing the expression of Th2 cytokines in the lungs, in addition to suppressing the volume of active oxygen created in the respiratory tract and suppressing the infiltration of inflammatory cells into the bronchi and relieving respiratory-tract hypersensitivity which constitute problems that cause asthma in in-vivo studies.
Abstract:
The present invention relates to an activin receptor type II B (ACVR2B) inhibitor which comprises the delta-like 1 homolog (DLK1) extracellular water-soluble domain. More specifically, the present invention relates to an extracellular soluble domain of DLK1; fragments of the extracellular soluble domain of DLK1; mutants of the extracellular soluble domain of DLK1; a composition for suppressing ligand linkage with the ACVR2B receptor, which includes a fragment of the mutants as an active ingredient; and a pharmaceutical composition for prevention and treatment of diseases which comprises the same. The composition of the present invention competitively binds to the ACVR2B receptor and inhibits the binding of an ACVR2B ligand to the ACVR2B receptor, which inhibits protein signalling associated with such ligands, and will be useful for prevention and treatment of diseases associated therewith.
Abstract:
The present invention relates to an effective differentiation and proliferation method for natural killer cells (NK cells) from cord blood, and more specifically, to a method for effectively differentiating and proliferating natural killer cells from cord blood, comprising the following steps: 1) removing CD3, CD34, CD56 and CD19 positive cells from cord blood-derived monocytes to prepare CD3-CD34-CD56-CD19 cells; 2) removing CD14-negative cells from the CD3-CD34-CD56-CD19 cells to prepare CD3-CD34-CD56-CD19-CD14-positive cells; and 3) mixing the CD3-CD34-CD56-CD19-CD14-positive cells with IL-15 and IL-21 and culturing the mixture. The present invention can obtain NK cells with a high purity within a short time by inducing NK cells from the CD14-positive cells, compared with a method inducing NK cells from hematopoietic stem cells. In addition, the present invention can induce NK cells with an excellent cell killing activity within a short time so as to differentiate the same into NK cells with a cancer cell killing properties, and thus can be useful for treatment of cancer cells.
Abstract:
The present invention relates to a cultivation container for living organisms, and more particularly, to a cultivation container for living organisms which does not become contaminated by external air when cultivating live tissue, and which allows safe and convenient addition or replacement of a medium. The cultivation container for living organisms, according to the present invention, comprises: an outer body, which is provided with an accommodation space having an open top and a coupling protrusion which is formed on the outer circumferential surface; an inner body, which is provided in the accommodation space of the outer body, and has an open top so as to accommodate the medium therein; an inner cover, which couples to the upper portion of the inner body, and is formed with protrusions on the upper surface and a medium insertion hole; and an outer cover, which couples to the upper portion of the outer body, and is formed with a coupling groove that corresponds to the coupling protrusion on the inner circumferential surface and an insertion concave groove that corresponds to the protrusion on the lower surface of the upper portion.
