Recently, the detection of occult cancer cells in peripheral blood has received a great deal of attention regarding the prediction of postoperative cancer recurrence and for novel strategies of adjuvant therapy. The aim of this study was to establish a new molecular diagnostic method of detecting circulating tumor cells. Gastric cancer SGC-7901 cells in 2(More)
OBJECTIVE The goal of our study was to investigate whether DRD4 gene DNA methylation played an important role in the susceptibility of Han Chinese SCZ. METHODS Using the bisulphite pyrosequencing technology, DNA methylation levels of 6 CpG dinucleotides in DRD4 CpG island were measured among 30 paranoid SCZ patients, 30 undifferentiated SCZ patients, and(More)
BACKGROUND The GCK gene encodes hexokinase 4, which catalyzes the first step in most glucose metabolism pathways. The purpose of our study is to assess the contribution of GCK methylation to type 2 diabetes (T2D). METHODS AND RESULTS GCK methylation was evaluated in 48 T2D cases and 48 age- and gender-matched controls using the bisulphite pyrosequencing(More)
OBJECTIVE TP53 K351N mutation is associated with acquired cisplatin resistance in ovarian cancer cells following exposure to cisplatin. We investigated the effect of TP53 K351N mutation on outcome in patients with epithelial ovarian cancer (EOC) who received platinum-based chemotherapy. METHODS We assessed TP53 K351N mutations by allele specific real-time(More)
Finding top-K influential nodes in social networks has many important applications. Previous work only considered that one node in the network can influence other nodes with a uniform probability, which doesn't take user preferences into account and greatly affects the accuracy of results. We propose a two-stage mining algorithm (GAUP) for mining most(More)
A low power 4-bit 2 GS/s flash ADC is presented. To enhance the speed, the analog part of the ADC is fully pipelined; reset switches are inserted into preamplifiers and comparators for fast overdrive recovery. Post-simulation results show that the peak DNL and INL are 0.04 LSB and 0.06 LSB, respectively. With 970.2 MHz input, the SFDR and ENOB achieve 33.2(More)
Piwi-interacting RNAs (piRNAs), new non-coding small RNAs, are association with chromatin organization, messenger RNA stability and genome structure. However, the roles of piRNA in carcinogenesis are not clearly defined. By using real-time reverse transcription-polymerase chain reaction technology, we found that the expression level of piR-823 in gastric(More)
This study aims to investigate the oxidative stress and hepatocellular injury induced by Cr(3+) in chicken. Different doses of CrCl3 solutions (50% LD50 , 25% LD50 , and 12.5% LD50) and equivalent water were orally administered to chicken. Chicken liver samples were measured for the activities of antioxidant enzymes, the contents of glutathione, total(More)
BACKGROUND Piwi-interacting RNAs (piRNAs) are a novel class of non-coding single strand RNAs. They are involved in germline development, in silencing of selfish DNA elements, and in maintaining germline DNA integrity. The relationship between piRNAs and carcinogenesis has not been shown yet. METHODS The relationship between piRNAs and carcinogenesis was(More)
This study aimed to evaluate the effects of adding chromic chloride (CrCl3) in the drinking water of chickens. Hyland brown male chickens were randomly divided into four groups. Three groups orally received 1/2 LD50, 1/4 LD50, and 1/8 LD50 CrCl3mgkg(-1) body weight daily for 42d. The fourth group was treated with water. The chickens were sacrificed at 14,(More)
