In this paper, a high-performance liquid chromatography coupled with ultraviolet detection and Fourier transform-ion cyclotron resonance mass spectrometry （HPLC-UV/FrICRMS） method was described for the investigation of impurity profile in moxifloxacin （MOX） drug substance and chemical reference substance. Ten impurities were detected by HPLC-UV, while eight impurities were identified by using the high accurate molecular mass combined with multiple-stage mass spectrometric data and fragmentation rules. In addition, to our knowledge, five impurities were founded for the first time in MOX drug substance.

In this paper we consider a single-machine scheduling model with deteriorating jobs and simultaneous learning, and we introduce polynomial solutions for single machine makespan minimization, total flow times minimization and maximum lateness minimization corresponding to the first and second special cases of our model under some agreeable conditions. However, corresponding to the third special case of our model, we show that the optimal schedules may be different from those of the classical version for the above objective functions.

This study aimed to identify the potential metabolic biomarkers of the Badagan constitution(BC) in Mongolian medicine. Serum samples from the participants with BCs(n = 32) and aggregative constitutions(n = 30) were analyzed by using ultrahigh-performance liquid chromatography/mass spectrometry. Meanwhile, principal component analysis and orthogonal partial least squares discriminant analysis were used to characterize the endogenous metabolites and potential biomarkers, respectively. Fifteen of the 18 biomarkers in six metabolic pathways were significantly upregulated,including phosphatidylserine, sphingolipids, tryptophan, riboflavin and glutathione, and three biomarkers were significantly downregulated,including lysophosphatidylcholine(LysoPC)(18:1), LysoPC(16:1), and lysophosphatidylethanolamine(LysoPE)(22:2). This study also implied that sphingolipid metabolism, glycerophospholipid metabolism, and tryptophan metabolism played important roles in the BC. Therefore, metabolomics may improve the diagnostic efficacy of the BC in terms of the accuracy and comprehensiveness of a diagnosis based on this constitution. This result further reveals the mechanism of the constitution type in Mongolian medicine and provides a reference for the treatment of related diseases.

Evaluation of the genetic effect on yield and fiber quality can provide useful information on cotton breeding. Sixteen CSB lines and TM-1 introduced from USDA/ARS were used as male and top-crossed with three elite cultivars and the 51 F1 hybrids, 16 CSB lines, TM-1, and 3 elite cultivars were planted at the Cotton Research Institute of CAAS, Anyang, Henan Province and Xiajin, Shandong Province, China. The yield traits and fiber quality data were obtained and additive and dominance effect on each trait were measured by AD model. Boll weight takes the largest additive proration, whereas boll number takes the least additive proration. The largest and the least dominant proration for lint yield and boll weight were measured, respectively. Fiber length has the additive and dominance effect, and dominance effect was slightly more than additive effect. Larger additive and no dominance effect on uniformity, micronaire, and fiber strength were measured. Significantly, positive additive effect on boll weight of CSB06 and CSB12Sh was observed. CSB14Sh and CSB01 have significantly positive additive effect on 4 and 3 traits of fiber quality, respectively. CSB01 has the greatest dominant effect on lint yield among CSB lines. The dominant effect on fiber length of CSB lines showed positive. It is beneficial to use CSB06 and CSB12Sh as parents to improve boll size, to use CSB14Sh and CSB01 as parents to improve fiber quality. As for hybrid cotton breeding, it is reasonable using CSB01 to improve lint yield traits, and using CSB01, CSB11Sh, and CSB06 to improve fiber length.

Abstract: For investigating the 4Σ- 4Σ- transition in the FO radical to which an observed 268 nm ASE line has been attributed. the potential energy energy of the four lowest-lying 4A2 states of FO have been calculated using the NIRSDCI method. The results indicate that the first 4Σ- (14A2) and the upper 4Σ- (44A2) States are weakly bound and bound states respectively, and the 24A2 and 34A2 States are both repulsive States which are not relevant to the emission. The predicted Te value for the 4Σ-→4Σ- transition is 4.62 eV, which is in excellent agreement with the photon energy value (4.63 eV) of the ASE line. The procedure of our MRSDCI calculations for excited states is described in detail, and the previous calculation results for these States are discussed.

Many studies have focused on soil nutrient heterogeneity and islands of fertility in arid ecosystems. However, few have been conducted on an oasis-desert transitional zone where there is a vegetation pattern changing from shrubs to annual herbs. The goal of the present study was to understand vegetation and soil nutrient heterogenity along an oasis-desert transitional zone in northwestern China. Three replicated sampling belts were selected at 200 m intervals along the transitional zone. Twenty-one quadrats （10 x 10m） at 50m intervals were located along each sampling belt. The vegetation cover was estimated through the quadrats, where both the soil under the canopy and the open soil were sampled simultaneously. The dominated shrub was Haloxylon ammodendron in the areas close to the oasis and Nitraria tangutorum dominated the areas close to the desert. In general, along the transitional zone the vegetation cover decreased within 660 m, increased above 660 m and decreased again above 1 020 m （close to the desert）. The soil nutrients （organic matter, total N, NO3^- and NH4^＋） showed significant differences along the zone. The soil nutrients except the soil NH4^＋ under the canopy were higher than those in open soil, confirming ＂islands of fertility＂ or nutrient enrichment. Only a slight downward trend of the level of ＂islands of fertility＂ for soil organic matter appeared in the area within 900 m. Soil organic matter both under canopy and in interspace showed a positive correlation with the total vegetation cover, however, there was no significant correlation between the other soil nutrients and the total vegetation cover. We also analyzed the relationship between the shrubs and annuals and the soil nutrients along the zone. Similarly, there was no significant correlation between them, except soil organic matter with the annuals. The results implied that annual plants played an important role in soil nutrient enrichment in arid ecosystem.
