摘要:
An integral brush is formed by performing steps of tufts arrangement, tufts insertion into mold, mold turning and closing, and injection molding, thereby forming no gaps between cleaning assembly and handle. The cleaning assembly includes at least one cleaning unit each having a plurality of tufts integrally formed with one of a plurality of bases in the handle. The tufts are spaced apart and an upper portion of each tuft is shaped to form an uneven tip. The brush can increase a contact area between the cleaning assembly and an object so as to effectively clean the object.

A copy protection method includes the steps of providing an optical storage device having a substrate layer and a data structure layer coated on the substrate layer and containing a set of raw data codes; forming on the data structure layer at least one polarizing layer capable of causing a change in a light beam; and forming on the polarizing layer a scratch protection layer. The polarizing layer is located between the data structure layer and an optical reading device to influence a light beam irradiated thereon by the optical reading device, so that the set of raw data codes being optically accessed is conditionally converted into a different set of physical data codes. By providing the polarizing layer on the optical storage device to change the data codes that can be obtained by the optical reading device, it is able to stop illegal copying of the optical storage device.

A novel synthesis method of Glyco-drug radiotracer precursor is revealed. After completing synthesis of Z-Gly-ah (main structure), galactosamine GalNAc(OAc)4 is added to have coupling reaction. Then a product is separated directly from dichloromethane. Thus loss of galactosamine during extraction with liquid chromatography is reduced. Moreover, instead of trifluoroacetyl group, carbobenzoxy (abbreviated as Cbz or Z) is used as a protecting group to ensure uniformity of the phase. The cost and synthesis time are also dramatically reduced.

One embodiment of the present invention provides a system stored on a non-transitory computer-readable storage medium for invoking a plug-in that is dynamically associated with a database operation. During operation, a client sends a request to a database system to perform an operation on the database, wherein the request includes a control-message which specifies a plug-in which needs to be executed. Next, the system executes the plug-in at a plug-in server to obtain a plug-in result. Then, the system determines if the plug-in result is an error identifier. If so, the system sends the error identifier to the client. On the other hand, if the plug-in result is not an error identifier, the system performs the operation to obtain an operation result. The system then sends the operation result to the client.

H3LMN series compounds used as radioactive agents for treatment of liver cancer and a manufacturing method thereof are revealed. 2-thioethylamine hydrochloride is reacted with triphenylmethanol for protection of thiol to obtain 2-[(triphenylmethyl)thio]ethylamine. Then obtain N-[2-((triphenylmethyl)thio)ethyl]chloroacetamide by a transamidation reaction between 2-[(triphenylmethyl)thio]ethylamine and chloroactyl chloride. Next produce a amine-amide-thiol ligand-N-[2-((triphenylmethyl)thio)ethyl][2-((triphenylmethyl)thio)ethylamino]acetamide by a substitution reaction of N-[2-((triphenylmethyl)thio)ethyl]chloroacetamide and 2-[(triphenylmethyl)thio]ethylamine. After respective reaction with 1-bromotetradecane, 1-bromohexadecane and ethyl 16-bromohexadecanoate, H3LMN series compounds are obtained. These amine-amide-dithiols quadridentate ligands can react with MO3+ (M=Tc or Re) to produce electrically neutral complexes. The complexes have high lipophilicity, allowing them soluble in lipiodol to be applied to radiation therapy for liver cancer.

摘要:
A radioactive mixture and a manufacturing method thereof are disclosed. The radioactive mixture (188Re-MN/Lipiodol mixture) is formed by chelating reaction of MN series compounds that are amine-amide-disulfide amine quadric-dentate chelate ligands with TcO4−/or ReO4−, and then dissolved in Lipiodol. Moreover, the 99mTc/or 188Re of the TcO4−/or ReO4− avoids bone marrow injuries caused by free 90Y. By the feature of the Lipiodol that stays in liver tumors for a long period, the radioactive mixture is applied to treat liver cancers by injection so that injuries caused by surgical operations can be prevented. 188Re-MN/Lipiodol is used for liver cancer, breast cancer or other solid tumors treatment. Re-188 MN or Re-188 MN/Lipiodol can be mixed with anticancer drugs, hydrogel, liposome, micelle or other nano-particles to form the multifunctional therapeutic modality.
