摘要： An ion beam generating device includes a liquid metal ion source configured to melt metal and emit an ion beam, and an extractor disposed under the liquid metal ion source and configured to extract the ion beam emitted from the liquid metal ion source. The liquid metal ion source includes a storage configured to accommodate the metal, an emitter configured to receive the metal from the storage and emit the ion beam, and a heater configured to heat the emitter or the storage. The heater is configured to directly heat the metal accommodated in the storage to melt the metal into a liquid state, and an amount of the ion beam to be extracted is controlled by a voltage difference that changes based on a distance between the emitter and the extractor.

摘要： The present invention relates to a biomarker for diagnosis of overactive bladder (OAB) disease, and a method for screening a drug using the biomarker. The markers described in the present invention can effectively detect or diagnose the onset of OAB by distinguishing them from normal populations. In particular, OAB-specific protein markers released into urine enable simple and rapid OAB diagnosis in a non-invasive manner. In addition, by selecting an agent that changes, particularly normalizes the expression and activity of the markers selected in the present invention, more effective preventative or therapeutic agents of OAB disease can be screened.

摘要： The present invention relates to a beef-specific age determination marker containing the p21 protein, to an antibody specifically bound to bovine p21 protein, to a beef-specific age determination kit containing the antibody which is specifically bound to the bovine p21 protein, and to a method which involves detecting the bovine p21 protein through an antigen-antibody binding reaction using the antibody which is specifically bound to the bovine p21 protein serving as a beef-specific age determination marker in the muscle tissue of beef, so as to determine the age of the beef. According to the present invention, the p21 protein is significantly greatly expressed in the muscle tissue of beef, the age of which is lower than 30 months, and is hardly expressed in the muscle tissue of beef, the age of which is greater than 30 months, and thus can be valuably used as a beef-specific age determination marker.
