Publication number: 20070048750Abstract: The present invention discloses a method for rapid assessment of lung cancer therapy efficacy in a few days instead of weeks by conventional imaging methods. This method can also be used to detect relapse of the cancer and to improve the current TNM cancer staging method for more accurate prognosis. The rapid assessment of therapy efficacy is based on detecting circulating cancer cells in body fluid with high positive detection rate. The high positive detection rate is achieved by using PCR amplification of multiple marker genes identified by in silico search of DNA sequence database. This invention also discloses a scoring method to calculate the cancer cell load based on PCR results to correlate the amount of circulating cancer cells in lung cancer patients with their treatment outcomes.Type: ApplicationFiled: December 31, 2005Publication date: March 1, 2007Applicant: NATIONAL HEALTH RESEARCH INSTITUTEInventors: Konan Peck, Yuh-Pyng Sher, Jin-Yuan Shih, Pan-Chyr Yang, Cheng-Wen Wu

Publication number: 20060253723Abstract: A semiconductor memory employs the redundancy memory technique and the error correction code technique and method of correcting errors. The method of correcting errors reads data bits and a checking bit from a predetermined unit of a first memory array such as a main memory array, and the data bits are checked based on the checking bit to determine if there is any error. If there is an error in the data bits, the checking bit is used to correct the error and the data bits together with the checking bit are written back to the predetermined unit. If there is still error in the data bits after the read-check-write process is repeated a predetermined number of times, the predetermined unit is marked as a faulty unit and the data bits together with the checking bit are written to a second memory array such as a redundancy memory array.Type: ApplicationFiled: August 4, 2005Publication date: November 9, 2006Applicant: NATIONAL TSING HUA UNIVERSITYInventors: Cheng-Wen Wu, Chin-Lung Su, Yi-Ting Yeh

Patent number: 6415403Abstract: In the present invention a built in self test (BIST) for an embedded memory is described. The BIST can be used at higher levels of assembly and for commodity memories to perform functional and AC memory tests. A BIST controller comprising a finite state machine is used to step through a test sequence and control a sequence controller. The sequence controller provides data and timing sequences to the embedded memory to provide page mode and non-page mode tests along with a refresh test. The BIST logic is scan tested prior to performing the built in self test and accommodations for normal memory refresh is made throughout the testing. The BIST also accommodates a burn-in test where unique burn-in test sequences can be applied.Type: GrantFiled: June 21, 1999Date of Patent: July 2, 2002Assignee: Global Unichip CorporationInventors: Jing-Reng Huang, Chih-Tsun Huang, Chi-Feng Wu, Cheng-Wen Wu

Patent number: 6218114Abstract: The invention relates to a method of detecting a differentially expressed gene in a first sample of nucleic acids representing a first population of RNA transcripts and a second sample of nucleic acids representing a second population of RNA transcripts. The nucleic acids in the samples are labled with a member of specific binding pair, and the labeled nucleic acids in each sample are then hybridized to an excess of copies of a gene-specific sequence. The hybridized nucleic acids in each sample are further labeled by binding a second member of the specific binding pair to the first member, in which the second member has an activity to convert a chromogenic substrate into a chromogen. As a result of contacting the second member with the chromogenic substrate, the chromogenic substrate is converted into the chromogen. A difference in the amounts of chromogen produced from assaying the two samples indicate that the gene-specific sequence is differentially expressed in the samples.Type: GrantFiled: March 27, 1998Date of Patent: April 17, 2001Assignee: Academia SinicaInventors: Konan Peck, Jeremy J.
