Comparative genomic analyses have revealed extensive colinearity in gene orders in distantly related taxa in mammals and grasses, which opened new horizons for evolutionary study. The objective of our study was to assess syntenic relationships of quantitative trait loci (QTL) for disease resistance in cereals by using a model system in which rice and barley(More)
ABSTRACT Bacterial blight, caused by Xanthomonas oryzae pv. oryzae, is a serious disease of rice worldwide. A new dominant gene for bacterial blight resistance in rice, Xa25(t), was identified from Minghui 63, a restorer line for a number of rice hybrids that are widely cultivated in China. This gene conferred resistance to Philippine race 9 (PXO339) of X.(More)
BACKGROUND Hemodynamic monitoring is very important in critically ill patients with shock or acute respiratory distress syndrome(ARDS). The PiCCO (Pulse index Contour Continuous Cardiac Output, Pulsion Medical Systems, Germany) system has been developed and used in critical care settings for several years. However, its impact on clinical outcomes remains(More)
A gas chromatography-mass spectrometric (GC-MS) method was established for the determination of cyromazine and its metabolite, melamine, in animal-derived food. Chicken and tilapia muscle samples were spiked with (15)N(3)-melamine, extracted with an acidic acetonitrile/water solution, and defatted with dichloromethane. Egg and milk samples were directly(More)
Recommendation systems are widely used to cope with the problem of information overload in digital libraries, consequently, many recommendation methods have been successfully applied in the present book recommendation systems, such as collaborative filtering, content-based, association rule mining-based and so on. But they are always lack of user’s(More)
A confirmatory method is presented for the determination of acrylamide in different food products by gas chromatography-mass spectrometry (GC-MS). The method is based on the extraction of acrylamide with and methanol, and purification with Carrez I zinc sulfate) and Carrez II (potassium hexacyanoferrate) solution, followed by bromination onto the acrylamide(More)
Causing potato brown rot, Ralstonia solanacearum (R. solanacearum) strains are reported as one of the most destructive bacteria to potato (Solanum tuberosum L.) in China. In this study, 113 strains were isolated from potato, collected in the four major agroecological zones in China. The study showed that 102 strains belonged to the phylotype IIB sequevar 1(More)
A method for the determination of three coriaria lactone residues in honey was developed using ultra high performance liquid chromatography-high resolution mass spectrometry. The honey samples were extracted with 0.2 mol/L phosphate buffer solution (pH = 7.5), and the extracts were cleaned up with Waters HLB solid phase extraction cartridges. The extracted(More)
A method for the determination of chloramphenicol in propolis was developed by high performance liquid chromatography-tandem mass spectrometry. The flavones were removed with lead acetate solution after the extraction of the sample with water. The extract was cleaned up by liquid-liquid extraction. Internal standard method was used for quantitative(More)
