Abstract:
A constant temperature agitating device for agitating substances received in a container comprises a base, a container receiving body part and a shaking motion part. The container receiving body part is positioned at an upper part of the base, and includes upper and lower body parts for covering the upper and lower parts of the container so as to receive the container, wherein the inner surfaces of the upper and lower body parts which contact with the container form a container receiving part corresponding to the outer surface of the container. The shaking motion part shakes the container receiving body part against the base. The container receives heat via the inner surface contacting with the container receiving part.
Abstract:
The present invention relates to a production method for an epoxy substrate exhibiting a nanopattern, comprising the stages of: (a) forming a titanium oxide film by anodization of a titanium substrate; (b) obtaining a titanium substrate having a concave shape formed on its surface by removing the titanium oxide film from the titanium substrate on which the titanium oxide film has been formed; (c) coating an epoxy resin onto the titanium substrate on which the concave shape has been formed; and (d) obtaining an epoxy substrate formed with a nanopattern of convex surfaces by removing the titanium substrate. In the production method of the present invention, an epoxy substrate formed with a nanopattern of convex surfaces is produced after anodizing titanium, coating an epoxy resin onto a nanopattern formed with a concave shape on the titanium surface, and removing the titanium substrate. This straightforward process makes it possible to efficiently produce an epoxy resin exhibiting a nanopattern for the measurement of blood coagulation formed with a fine pattern which is uniform and on the nano scale. Further, the epoxy substrate produced by means of the present invention makes it possible to efficiently use an electrochemical technique to ascertain whether or not blood coagulation is present in a blood sample.
Abstract:
The present invention relates to a batroxobin-encoding nucleotide sequence and/or a mutated a-factor secretion signal sequence, and a vector and a transformant using the same. The batroxobin-encoding nucleotide sequence of this invention exhibits an excellent expression efficiency in yeast, particular Pichia pastoris and the recombinant batroxobin is obtained at 4-13 fold higher yield than natural-occurring batroxobin-encoding sequences. The protein expression system which uses the batroxobin-encoding nucleotide sequence as well as mutated a-factor secretion signal peptide sequence of this invention obtains the recombinant batroxobin at about 20-fold higher yield than natural-occurring batroxobin-encoding sequences. In addition, the recombinant batroxobin prepared using the sequence of this invention has a significantly plausible activity and stability compared with natural-occuring batroxobin.
Abstract:
A method for solubilization of curcumin and a water-soluble curcumin prepared by this method are disclosed. The method prepares a water-soluble curcumin by covalent-bonding sugar to the curcumin, thereby making the curcumin, which was insoluble to water, into a water-soluble curcumin. This water-soluble curcumin may be applied to more fields such as food, soluble drugs and dyes.
Abstract:
The present invention relates to liposome complex comprising a novel disintegrin, saxatilin, gene derived from Agkistrodon saxatilis and methods for curing and preventing tumors by transferring the complexes to a living body.
Abstract:
The present invention relates to core-shell nanoparticles comprising: a manganese-containing magnetic nanoparticle (Mn-MNP) multi-core; and a silica shell coating the multi-core. Since the core-shell nanoparticles used in the present invention have high saturation magnetization (Ms) value and transverse relaxivity (R2), a sensor of the present invention using the same can detect analytes with remarkably improved sensitivity. It is possible to detect a trace amount of analytes, for example, a protein or a nucleic acid molecule as an anti-cancer marker in the blood, a chemical material, and the like with the improved sensitivity. Therefore, the core-shell nanoparticles of the present invention can be useful in an effective and practical magnetic nanoparticle system and a magnetic sensing method or a contrast medium using the same due to excellent magnetic characteristics, in vivo non-toxicity, high solubility and easy surface modification.

The present invention relates to a pharmaceutical composition for preventing or treating hyperproliferative vascular disorders, and a pharmaceutical anticancer composition comprising the compound represented by the Formula 1. The present compounds exhibit IC 50 values of less than 0.16 μM for vascular smooth muscle cells and cancer cells to effectively prevent proliferation of vascular smooth muscle cells and cancer cells, thereby ensuring prevention or treatment of hyperproliferative vascular disorders such as arteriosclerosis and restenosis, and cancers.
Abstract:
A recombinant thrombin-like enzyme batroxobin expressed by yeast, a production method thereof, and use of the batroxobin as a hemostatic agent or antithrombotic agent is disclosed. In order to express recombinant thrombin-like enzyme, an expression vector is prepared by inserting cDNA encoding the enzyme, the transformed cell is prepared by introducing the expression vector into the cell, the transformed cell then is incubated and the recombinant thrombin-like enzyme is obtained from the cell. The recombinant thrombin-like enzyme may be usefully used as a hemostatic agent because the enzyme effectively decrease bleeding time and blood coagulation time and does not affect various blood coagulation factors. The recombinant thrombin-like enzyme is also useful for a hemostatic agent or antithrombotic agent comprising the recombinant thrombin-like enzyme as an active component.
