Disclosed is a method of producing toner. According to the method, a concentration of a dispersion stabilizer, a concentration of an aggregating agent, and a concentration of a hydrogen ion in a reaction solution of an aggregation process are controlled to produce toner particles having a narrow particle size distribution and excellent fixability, and providing a high quality image.

摘要:
Disclosed are a cell line that expresses protein of Seq. No. 1, and a method for screening an anticancer compound of uterine cervical cancer by using the same. The stable cell line that expresses oncoprotein E6 of a human papillomavirus type 16 variant strain is used to determine a difference in amounts of expression of tumor suppressor genes, such as p53, between E6 protein of the reference strain and E6 protein of a variant strain, thereby screening an anticancer compound of uterine cervical cancer, etc. Further, it is possible to develop an anticancer agent of uterine cervical cancer.
摘要:
A novel mutation in the SCN5A gene is associated with loss of cardiac sodium channel function. Analysis of the novel mutation provides an early diagnosis of subjects with cardiac diseases or disorders caused by loss of cardiac sodium channel function, particularly Brugada syndrome. Diagnostic methods include analyzing the sequences of the SCN5A gene or protein of an individual to be tested and comparing them with the sequences of the native, nonvariant SCN5A gene or protein. Pre-symptomatic diagnosis of these syndromes will enable practitioners to treat these disorders using existing medical therapy, e.g., using sodium channel blockers or through electrical stimulation.
