Provided is a method and apparatus for predicting a posttraumatic behavior problem that may predict a posttraumatic violent behavior problem of an individual, in detail, that may determine a biological phenotype of an individual experiencing a traumatic event within a predetermined period after the individual is exposed to the traumatic event, predict a violent symptom presentation probability of the individual based on the biological phenotype of the individual, and suggest an objective basis for preventive intervention in a development of posttraumatic stress disorder (PTSD) of the individual based on a prediction result.
Abstract:
Provided are a composition for diagnosing vascular disease including an agent measuring a level of interleukin 12 receptor β2 protein in the blood, and a kit for diagnosing vascular disease including the same. Further, provided is a method of providing information for diagnosing vascular disease, the method including the step of measuring a level of interleukin 12 receptor β2 protein in a blood sample separated from an individual suspected of having vascular disease. Furthermore, provided are a composition for preventing or treating vascular disease including an interleukin 12 receptor β2 activity inhibitor, and a method of screening a therapeutic agent for vascular disease, the method including the step of treating smooth muscle cells with a test agent for vascular disease treatment and measuring an expression level of interleukin 12 receptor β2. According to the present invention, when interleukin 12 receptor β2 is used as a biomarker for vascular disease, in particular, myocardial infarction or unstable angina, vascular disease, of which diagnosis has been performed only by angiography, can be diagnosed using blood in a rapid non-invasive economic manner. Accordingly, the early diagnosis of vascular disease is possible, since the disease has been diagnosed based on subjective symptoms after the appearance of ischemic symptoms with development of the disease. The promise of early diagnosis, prevention and treatment is realized.
Abstract:
The present invention relates to a method for preparing microsphere1- and microspheres produced by thereby. More particularly, the present invention relates to a method for preparing a polymeric microsphere comprising the steps of: mixing a water-insoluble organic solvent with a dispersion solvent; mixing a polymer compound, a drug and a water-insoluble organic solvent so as to prepare a dispersed phase; mixing the dispersed phase with the dispersion solvent mixed with the water-insoluble organic solvent so as to prepare an emulsion; and adding a base or an acid to the prepared emulsion so as to remove the water-insoluble organic solvent from the emulsion and a polymeric microsphere thereby, and a composition for drug delivery comprising the microspheres. In the inventive preparation method, it is possible to conveniently prepare a drug-containing polymeric microsphere within a short time using a small amount of water, with the generation of a minimized amount of waste solution without a requirement of a conventional solvent-evaporation or solvent-extract ion process. Also, since a low concentration of remaining solvent within a prepared polymeric microsphere can be maintained, it is effective in preparation in sustained-release type medicines.
