摘要:
This application relates to monomers of the general formula (I) for the preparation of PNA (peptide nucleic acid) oligomers and provides method for the synthesis of both predefined sequence PNA oligomers and random sequence PNA oligomers: wherein E is nitrogen or C—R′; J is sulfur or oxygen; R′, R1, R2, R3, R4 is independently H, halogen, alkyl, nitro, nitrile, alkoxy, halogenated alkyl, halogenated alkoxy, phenyl or halogenated phenyl, R5 is H or protected or unprotected side chain of natural or unnatural α-amino acid; and B is a natural or unnatural nucleobase, wherein when said nucleobase has an exocyclic amino function, said function is protected by protecting group which is labile to acids but stable to weak to medium bases in the presence of thiol.

The present disclosure provides method, system, and computer readable medium for shared execution of software. The present disclosure relates to method, system, and computer readable recording medium for shared execution of software involving identifying the main modules of a specific software by analyzing its control flow, data flow, and modular structure through a static binary analysis and a runtime profiling, i.e. dynamic analysis, separating the modules from the main software body to store them in a secure environment of a smart card, and storing the main body in a user terminal with the identified modules removed and replaced by an interface code, whereby a co-processing the software at the user's end by the smart card in engagement with the user terminal exclusively enables an execution of the software.
摘要:
The present invention relates to a marker for predicting a gastric cancer prognosis, a composition and a kit for predicting gastric cancer prognosis comprising an agent for measuring the expression level thereof, and a method for predicting gastric cancer prognosis using the marker. According to the present invention, gastric cancer prognosis may be predicted promptly and accurately, and an appropriate treatment plan can be determined based on the predicted prognosis, which has an advantage of contributing to significant reduction of death caused by gastric cancer. Particularly, according to the present invention, the survival rate can be remarkably increased by using the treatment method for a stage III gastric cancer patient to a patient who has been predicted to have a negative prognosis among stage Ib/II gastric cancer patients.
