To better determine the history of modern birds, we performed a genome-scale phylogenetic analysis of 48 species representing all orders of Neoaves using phylogenomic methods created to handle genome-scale data. We recovered a highly resolved tree that confirms previously controversial sister or close relationships. We identified the first divergence in(More)
The relationship between glutathione S-transferases (GSTs) M1, T1 genotype and childhood acute lymphoblastic leukemia (ALL) was investigated. GSTM1 and GSTT1 genotypes in genomic DNA from 67 children with ALL and 146 healthy controls were analyzed by using the multiplex polymerase chain reaction (PCR). The frequencies of GSTM1, M1-T1 null genotypes in ALL(More)
The mammalian target of rapamycin is an evolutionarily conserved serine-threonine kinase (mTOR), which controls protein synthesis and catabolism in response to environmental cues. This randomized double-blind clinical trial enrolled 60 abstinent heroin addicts and randomly assigned them to three groups: placebo, 2.5 mg and 5 mg rapamycin. The participants(More)
PURPOSE To assess the value of transcatheter intraarterial methotrexate infusion combined with selective uterine artery embolization (UAE) as a treatment option for cervical pregnancy. MATERIALS AND METHODS Between January 2004 and June 2009, a prospective study was conducted in 20 consecutive patients with cervical pregnancy. The patients were treated(More)
BACKGROUND Determining the evolutionary relationships among the major lineages of extant birds has been one of the biggest challenges in systematic biology. To address this challenge, we assembled or collected the genomes of 48 avian species spanning most orders of birds, including all Neognathae and two of the five Palaeognathae orders. We used these(More)
DA (D-blood group of Palm and Agouti, also known as Dark Agouti) and F344 (Fischer) are two inbred rat strains with differences in several phenotypes, including susceptibility to autoimmune disease models and inflammatory responses. While these strains have been extensively studied, little information is available about the DA and F344 genomes, as only the(More)
In order to solve the realistic problems in the teaching and experiment of computer network courses, a NS2-based demonstration and experiment system for computer network courses has been constructed. This system is made up of two parts, one of which is the demonstration system for teachers to demonstrate in class, and the other is the experiment system for(More)

The objective of this study is to construct an easy operational model to evaluate the performance of the Reverse Logistics management. To fulfill this mission, the main contributions were made as following: a) Defining the indicators of each factors related with performance of the RL management. CSFs (Critical Success Factors) method was employed in this(More)
Pedestrian detection is a key technology in autonomous driving perception system. Although the current vision-based pedestrian detection has obtained very good detection performance, the camera is sensitive to light and shadow. In addition, it is unable to provide precise location information, which is difficult to address autonomous driving problem. To(More)
