Abstract:
The present invention relates to a process for optimizing the recoverability of lyophilized microspheres for emboli and to chitosan microspheres to which a drug-containing carrier is bound. More particularly, the present invention relates to a recoverability optimization process for adding trehalose as a lyophilization protectant prior to a lyophilization for the stable storage of microspheres, and swirling the lyophilized microspheres in order to rehydrate the microspheres. The present invention also relates to microspheres in which the quantity of the drug released from the chitosan microspheres having a drug-containing nanocarrier bound thereto is adjusted based on a drug/chitosan ratio, thus enabling precise drug release adjustment. The present invention also relates to a method for preparing the microspheres. The optimization process of the present invention has the advantages of maintaining the physical properties, shape, and the drug release speed of the microspheres even after the lyophilization of the microspheres for emboli. The chitosan microspheres to which a drug-containing carrier is bound according to the present invention may stably cause emboli in blood vessels, and may precisely adjust the release of a drug and therefore can be used in cancer treatment.
Abstract:
The present invention relates to a method for enhancing the production yield of human papillomavirus (HPV) L1 protein, comprising a step of culturing cells expressing HPV L1 protein in a medium containing a high concentration of a total carbon source. According to the culturing method using a medium containing a high concentration of a carbon source, the production yield of HPV L1 protein can be remarkably enhanced, and furthermore, the immunogenicity of the produced L1 protein can be greatly increased.
Abstract:
The present invention relates to the use of the UPR signaling pathway genes IRE1 and HXL1 for treatment of fungal infection and meningitis. In the invention, it was newly found that disruption of Ire1 and Hxl1 (HAC1 and XBP1-Like gene 1) proteins, newly identified in Cryptococcus neoformans, genes encoding the proteins, provides an antifungal effect and a meningitis-treating effect. Based on this finding, a candidate which can show a synergistic effect when being co-administered with an existing antifungal agent or meningitis-treating agent can be screened and a novel pharmaceutical composition having an antifungal effect and a meningitis-treating effect can be provided.
Abstract:
The present invention relates to a construct for expressing rotavirus complex antigens having heterologous virus antigen epitopes, to a vaccine composition comprising the rotavirus complex antigens, to rotavirus-like particles comprising the rotavirus complex antigens, and to a vaccine composition comprising the rotavirus-like particles. According to the present invention, complex antigens comprising both the rotavirus antigens and epitopes of heterologous viruses different from the rotaviruses, and rotavirus-like particles comprising the complex antigens can be mass-produced at low costs. The method of the present invention can be applied to the study and development of novel complex vaccines against rotaviruses and heterologous viruses.
Abstract:
The present invention relates to a method for diagnosing prostate inflammation, and to a kit using the method. More particularly, the present invention relates to a method for diagnosing prostate inflammation by measuring the expression of CAMP (human cathelicidin antimicrobial peptide) in a prostate tissue sample taken from a subject, and to a prostate inflammation diagnostic kit including a primer, probe, or antibody capable of measuring the expression of CAMP. The present invention is based on the correlation between an increase in CAMP expression level in prostate tissue or cells and the occurrence of prostate inflammation. According to the method and kit of the present invention, accurate and quick diagnosis of prostate inflammation can be performed on a large scale using a simple molecular biological analysis.
Abstract:
The present invention provides a signal detection method and apparatus in a spatial multiplexing system. According to the present invention, the signal detection apparatus of a single receiver is formed with a plurality of antennas in a system in which at least one transmitter transmits data streams by a spatial multiplexing method, the signal detection apparatus comprises: a partial linear coefficient generator which generates a linear weight matrix by using the preset algorithm in a channel matrix that is formed between the at least one transmitter and a single receiver; a partial symbol eliminator which generates a first symbol vector by eliminating all transferable symbols of each transmission antenna in all of the data streams received; and a partial symbol detector which generates a transmission symbol candidate vector by using the first symbol vector and the generated linear weight matrix. Thus, according to the present invention, there is no big performance difference of errors between the data streams.
Abstract:
The present invention provides a device and method for transmitting a relay synchronization signal on an LTE-A system based on orthogonal frequency division having a multi-hop relay. In one example of the present invention, the device for transmitting a relay synchronization signal employs a synchronization signal for synchronization between a relay and a base station, and for synchronising one relay and a lower relay, and also for synchronization with a terminal for the purpose of having one relay monitor a neighbouring base station or relay; the synchronization signal being employed in such a way as to generate a relay synchronization signal having low correlation properties and having the same PAPR characteristics as the synchronization signal, and also to generate a frame comprising a relay synchronization signal.
Abstract:
The present invention is related to a composition comprising the extract of Rumex Aquaticus Herba for the prevention and treatment of gastritis disease or ulcer disease and the use thereof. The inventive extract significantly decreasethe area of damaged gastric lesion caused by acute gastritis when the inventive extract of the present invention was orally administrated to indomethacin-induced acute gastritis animal model. The inventive compositions according to the present invention are useful in the prevention and treatment of gastritis disease or ulcer disease.
Abstract:
The present invention relates to a recombinant expression vector for expressing brazzein and to a method for the mass production of brazzein using the vector, in which a brazzein expression system is constructed in Kluyveromyces lactis, which is a lactose-fermenting yeast, and particularly, in which an optimum condition is established to achieve significantly superior expression than conventional E. coli or yeast expression systems, thus enabling the mass production of brazzein. In addition, the present invention relates to a novel biquadratic brazzein variant having greater sweetness, which has the same thermal stability as that of conventional brazzein, and a sweetness that is at least 15 to 50 times higher than that of conventional brazzein. Therefore, the brazzein variant of the present invention can be used together with other sweeteners such as sugar (sucrose), and further less brazzein variant may be used as a substitute for the same amount of sugar, and can be variously used as additives in food production.
