A novel method for the determination of five carbamate pesticides （metolcarb, carbofuran, carbaryl, isoprocard and diethofencard） in water samples was developed by dispersive liquid-liquid microextraction （DLLME） coupled with high performance liquid chromatography-diode array detector （HPLC-DAD）. Some experimental parameters that influence the extraction efficiency were studied and optimized to obtain the best extraction results. Under the optimum conditions for the method, the calibration curve was linear in the concentration range from 5 to 1000 ng mL^-1 for all the five carbamate pesticides, with the correlation coefficients （r^2） varying from 0.9984 to 0.9994. Good enrichment factors were achieved ranging from 80 to 177- fold, depending on the compound. The limits of detection （LODs）（S/N = 3） were ranged from 0.1 to 0.5 ng mL^-1. The method has been successfully applied to the analysis of the pesticide residues in environmental water samples.

This study aimed to profile the chemical constituents of Zi-Shen pill(ZSP) and its metabolites in plasma, urine, and prostate tissue, after administration into rats. Based on the chromatographic retention behavior, fragmentation patterns of chemical components, published literatures, and literature databases, an UPLC-Q-TOF/MS(LC-TOF/MS) method was established to identify the components of ZSP and its metabolites in biological samples. A total of 101 compounds were identified and tentatively characterized from the ZSP, including alkaloids, xanthones, and timosaponins. Except for 33 prototype components, 22 metabolites were detected in the plasma, urine, and prostate, and mainly came from Phellodendri Amurensis Cortex and Anemarrhenae Rhizoma. It was found that glucuronidation and sulfation were the major metabolic processes of xanthones, while oxidation, demethylation, and glucuronidation were the major metabolic pathways of alkaloids. In summary, the present study provided important chemical information on the metabolism of ZSP, indicating that alkaloids might be able to be absorbed into the prostate. The results provided a basis for further studies of the mechanisms of action for ZSP.

Spinal cord injury necessitates effective rehabilitation strategies, with exercise therapies showing promise in promoting recovery. This study investigated the impact of rehabilitation exercise on functional recovery and morphological changes following thoracic contusive spinal cord injury. After a 7-day recovery period after spinal cord injury, mice were assigned to either a trained group(10 weeks of voluntary running wheel or forced treadmill exercise) or an untrained group. Bi-weekly assessments revealed that the exercise-trained group, particularly the voluntary wheel exercise subgroup, displayed significantly improved locomotor recovery, more plasticity of dopaminergic and serotonin modulation compared with the untrained group. Additionally, exercise interventions led to gait pattern restoration and enhanced transcranial magnetic motor-evoked potentials. Despite consistent injury areas across groups, exercise training promoted terminal innervation of descending axons. In summary, voluntary wheel exercise shows promise for enhancing outcomes after thoracic contusive spinal cord injury, emphasizing the role of exercise modality in promoting recovery and morphological changes in spinal cord injuries. Our findings will influence future strategies for rehabilitation exercises, restoring functional movement after spinal cord injury.

操控原子玻色-爱因斯坦凝聚体在双势阱中的动力学通常是通过改变势阱深度来实现,本文提出了一种基于调节原子有效质量的控制方案,可以在不改变双阱势的前提下操控凝聚体的双阱动力学.利用双模近似,本文解析地导出了超冷原子在双阱势中的隧穿强度和相互作用强度对有效质量的依赖关系,并基于平均场近似数值模拟了在有效质量调节下的凝聚体动力学演化,展示了隧穿振荡和自束缚等典型的双阱动力学行为.此外,本文的研究还发现,借助负有效质量效应,这一方案甚至可以等效地实现对负散射长度原子凝聚体双阱动力学行为的操控.

文章基于支付能力原则提出一种国际差异化协调碳税政策(CEDS),在此政策下一国碳税税率与其人均GDP水平正相关;采用环境版全球贸易分析模型,定量地评估CEDS的减排效果和对不同区域的经济影响。结果表明:相比于碳关税政策,CEDS减排效果更为明显,世界碳泄露较小;与碳关税政策相比,实施全球合作的CEDS政策,世界总的GDP和居民福利均有不同程度的改善;特别的,绝大多数发展中国家福利损失较小;发展中国家基于CEDS在国内减排,也能在一定程度上降低发达国家关于单方面减排措施所导致的竞争力损失的担忧。

新丝绸之路经济带建设是我国政府致力推进的一项重大对外战略。运用全球贸易分析模型定量评估新丝绸之路经济带核心区(即中国与中亚五国)一体化发展的影响,发现推进新丝绸之路能为沿线国家带来不同的经济增长效应和福利改善效果,是一个多方共赢的战略。新丝绸之路经济战略实施,能减少或消除各参与国间贸易壁垒,促进国际贸易往来。量化评估中国与中亚五国经济一体化的影响,在产业方面,较为突出的是纺织业、纤维作物、皮革及其制品、木材制品等。新丝绸之路经济带的推进会给各参与国带来显著的行业分布差异,长期看会引致产业结构改变。有关结论将为我国推进新丝绸之路建设的对外战略提供决策支持。
