Publication number: 20130345295Abstract: An oncolytic adenovirus vector and its potential application in cancer treatment and vaccination. The inventive vector (named Ad-TD-hIL12) is derived from the human adenovirus group C type 5, more particularly including deletion of three adenovirus genes E1A-CR2, E1B19K and E3gp-19K, and a fused cDNA sequence of p35 and p40 subunit of human IL12 placed under the control of the E3gp-19K promoter. The invention also includes a method to construct the triple gene-deleted vector (Ad-TD). The Ad-TD-hIL12 and Ad-TD-shIL12 (with a short p40 sequence of human IL 12) vectors can be used as targeted, genetically engineered agents for treatment of various solid tumors, via not only intratumoral injection, and also in intraperitoneal injection, without causing significant side effects, showing a superior antitumor efficacy and safety.Type: ApplicationFiled: September 2, 2013Publication date: December 26, 2013Applicant: Beijing Bio-Targeting Therapeutics Technology Inc.Inventors: Yaohe WANG, Guozhong JIANG, Pengju WANG, Dongling GAO, Nick LEMOINE

Patent number: 7081567Abstract: Disclosed is a method for making a bioreactor comprising a foreign target gene, special selectable markers and Dunaliella Salina as host. It is prepared by the genetic transformation techniques that include introducing a foreign target gene into the cells of Dunaliella Salina and screening the transformed cells of Dunaliella Salina. The bioreactor of the present invention can be used as a safe and cheap production system for proteins of pharmaceutical interest including vaccines, especially oral products, in a large scale, because the cells of Dunaliella Salina are easy of genetic manipulation in preparation of the bioreactor, nontoxic and edible for humans and animals, and harmless to the environment.Type: GrantFiled: November 29, 2001Date of Patent: July 25, 2006Assignees: Zhengzhou UniversityInventors: Lexun Xue, Weidong Pan, Guozhong Jiang, Jianmin Wang

Patent number: 6525694Abstract: A high gain printed loop antenna comprises a first and second loop arranged symmetrically about a feed network, wherein each of the loops include pairs of substantially parallel radiation sections which when excited in phase from the feed network improves the gain of the antenna. Each of the parallel radiation sections are joined by patch elements such that the width of the patch elements is greater than the width of other portions of the loop. Thus, the patch elements allow for an increased variance in the path of a surface current through the loop.Type: GrantFiled: July 25, 2001Date of Patent: February 25, 2003Assignee: Superpass Company Inc.Inventors: Guozhong Jiang, Xifan Chen, Luke Zhu
