Publication number: 20230033016Abstract: The invention relates to a method for diagnosing or identifying gastric cancer in a subject. The inventors indeed identified three DNA methylation biomarkers that, alone, or preferably in combination, can help diagnosing or following-up gastric cancer patients very specifically, discriminating with other type of cancers. Further, it can be used for determining, and/or adapting a suitable therapeutic regimen for a subject diagnosed for gastric cancer. The present invention also relates to kits comprising primers or probes to detect, diagnose, or identify hypermethylated genes.Type: ApplicationFiled: June 22, 2020Publication date: February 2, 2023Inventors: Shufang Wang-Renault, Valérie Taly, Pierre Laurent-Puig, Aziz Zaanan

Patent number: 11306350Abstract: Specific, accurate, and cost effective primers for performing digital PCR, compositions and kits containing the primer and methods for using and making the same are useful for detecting nucleic acid mutations. A primer useful as a first forward primer in performing digital PCR to detect a target nucleic acid in a sample, includes: a detection portion located upstream to a target sequence binding portion, and including a second forward primer binding portion having a sequence substantially complementary to a second forward primer, and a probe binding portion downstream to the second forward primer binding portion having a sequence substantially complementary to a probe; the target sequence binding portion includes a mismatch portion having a sequence not complementary to the target nucleic acid, and an amplification determinant portion downstream to the mismatch portion having a sequence complementary to a gene allele or a variant thereof encoded by the target nucleic acid.Type: GrantFiled: April 15, 2019Date of Patent: April 19, 2022Assignee: Maccura Biotechnology Co., Ltd.Inventors: Yuhang Zhao, Shufang Wang, Zhiqi Ge

Patent number: 9174183Abstract: The invention provides a fluidized bed polymerization reactor, including: a column, in which a liquid distributor and a gas distributor above the liquid distributor are arranged, so that the reaction zone being divided into a first zone and a second zone through the gas distributor; and a circulating unit for circulating the gas material originated from the top zone of the column into the bottom zone thereof in a form of gas-liquid mixture. The gas-liquid mixture is undergone a gas-liquid separation in the bottom zone, the gas phase portion obtained being fed to the gas distributor and then into the second zone while the liquid phase portion obtained being entered into the first zone through the liquid distributor, so that the temperature in the first zone is lower than that in the second zone. Therefore, polymer with a molecular weight distributed in a relatively wide range can be obtained. The invention further provides a method for preparing polymer.Type: GrantFiled: September 29, 2011Date of Patent: November 3, 2015Assignees: China Petroleum & Chemical Corporation, Zhejiang University, Sinopec Engineering IncorporationInventors: Wenqing Wu, Yongrong Yang, Guanghai Luo, Jingdai Wang, Binbo Jiang, Shufang Wang, Guodong Han
