AIM To evaluate the association of glutathione S-transferases gene polymorphisms with the risk of gastric cancer, with reference to smoking and Helicobacter pylori infection. METHODS We conducted a 1:1 matched case-control study with 410 gastric cancer cases and 410 cancer-free controls. Polymorphisms of GSTM1, GSTT1 and GSTP1 were determined using(More)
The multiple small-scale association studies of candidate genes for type 2 diabetes mellitus in the Chinese Han population have shown inconsistent results. Here, we performed a meta-analysis to evaluate the contribution of five candidate genes to the pathogenesis of type 2 diabetes in the Chinese Han population. We searched for relevant published papers and(More)
CF (cystic fibrosis) is a recessive genetic disease caused by mutations of the CFTR (cystic fibrosis transmembrane conductance regulator), a cAMP-activated anion channel, exhibiting a multitude of clinical manifestations including lung inflammation/infection, pancreatic insufficiency/diabetes, intestinal obstruction and infertility in both sexes. While(More)
One of the challenging scheduling problems in Cloud datacenters is to take the allocation and migration of reconfigurable virtual machines into consideration as well as the integrated features of hosting physical machines. We introduce a dynamic and integrated resource scheduling algorithm (DAIRS) for Cloud datacenters. Unlike traditional load-balance(More)
Gliomas, with a poor clinical course, account for 30% to 40% of all intracranial tumors. Immunotherapy with monoclonal antibodies has emerged as a promising area of investigation and recently it has been shown that antibodies utilize complementarity-determining regions (CDRs) of their variable domains to bind to antigens with high affinity and specificity.(More)
AIM An epidemiological study was conducted based on an esophageal cancer patient's cohort to investigate the association of folate intake and MTHFR C677T polymorphism with the prognosis of esophageal cancer in a Chinese population. METHODS 167 patients aged 37-75 years who had histological confirmed diagnosis of esophageal squamous cell cancer were(More)
Planning of Tracking and data relay satellite is a important problem which focuses much attention recently. Based on the analysis of operation planning for tracking and data relay satellite (TDRS), a new approach of modeling of operation planning based on state and action models is proposed, which has powerful representation capabilities compared with(More)
Establishing high performance cooperation and estimating the nodes’ risk in mobile ad hoc networks (MANETS) is currently fundamental and challenging due to the inherent characteristics of MANETS, such as highly dynamic topology and absence of an effective security mechanism. Trust based assessment methods were recently put forward but presumed(More)
