Differentialiy expressed polypeptides in the brain of a BALB/c mouse model infected with scrapie strain 22L were analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The results showed that 21 peptides were down-regulated, with peptides of mass-to-charge ratio 758.772 5 and mass-to-charge ratio 5 432.206 9, demonstrating the most significant decreases. These finding suggest that these peptides are candidate biomarkers and may play an important role in the pathogenesis of prion disease.

作者： Yifan Xing wensen Huang Jinhui Zhao Shenzhen Quantum Wisdom Culture Development Co. Ltd. Shenzhen China Department of Physics The University of Hong Kong Hong Kong China College of Mechanical and Electrical Engineering China Jiliang University Hangzhou China

This paper proposes the continuous controller design method for quantum Shannon entropy, which can continuously drive the entropy to track a desired trajectory. We also analyzed the controllability of Shannon entropy in very short time interval. Simulations are done on five dimensional quantum system, which can verify the validation of the method.

在图像采集过程中,由于拍摄对象运动或相机自身运动造成的图像模糊对于后续的高级视觉任务会产生很不利的影响。针对当前深度学习图像去模糊方法不能兼顾去模糊效果和效率的问题,提出了一种多尺度循环注意力网络,使用深度可分离卷积降低参数量,改进注意力模块合理分配计算资源,对卷积层进行密集型连接提高参数利用效率,引入边缘损失提升生成图像边缘细节信息。经过实验验证,所提方法具有良好的泛化性能和鲁棒性,在Lai数据集和K?hler数据集上的SSIM和PSNR较近年典型方法的最佳效果分别提升了约1.15%、0.86%和0.91%、1.04%,在GoPro数据集上的平均单帧运行速度较同类方法提升约2.5倍。

A Method for Rapid Determination of Polymer Dissolution Time

Journal of Materials Science and Chemical Engineering 2020年第5期8卷 1-9页

作者： Juan Zhao Jian Zhang wensen Zhao Wenjuan Chen Haiyan Guo Quan wang Zhao Hua Guang Yang CNOOC Research Institute Co. Ltd. Beijing China State Key Laboratory of Offshore Oil Exploitation Beijing China Sinopec Shengli Oil Production Plant Oil Production Management Zone 5 Dongying China

In view of the limited space of offshore platform and the large amount of polymer injection, the dissolution time method, solution viscosity method, conductivity method, undissolved filtration method and falling ball method are used as the rapid detection methods of polymer dissolution. The results show that the error of conductivity method is the largest, and that of dissolution time method is the second, and both methods are time-consuming. Solution viscosity method and insolubles filtration method have small error, but they are time-consuming, especially for offshore platforms, which makes detection inconvenient. The drop ball method is simple in operation and has a small error, so it is a promising method for rapid determination of polymer dissolution time.

Tributyrin is more effective than tripropionin in reducing plasma cholesterol in hypercholesterolemic hamsters

引用

Food Science and Human Wellness 2024年

作者： Shouhe Huang Chi Yan Huafang Ding Zixing Chen Hanyue Zhu wensen He Lin Lei Zhen-Yu Chen Food and Nutritional Sciences Program， School of Life Sciences， Faculty of Science， The Chinese University of Hong Kong School of Food Science and Engineering/Guangdong Provincial Key Laboratory of Intelligent Food Manufacturing， Foshan University School of Food and Biological Engineering， Jiangsu University College of Food Science， Southwest University

Propionate and butyrate are proven capable of decreasing plasma cholesterol. However， their undesired odor and unpleasant smell limit their direct application as a dietary supplement. In contrast， their respective triacylglycerols tributyrin (Tb) and tripropionin (Tp) are odorless and can be directly used as healthy supplements. In view that no study has investigated the relative biological potency of Tb and Tp， the present study was designed to compare the effects of Tp and Tb on plasma cholesterol and gut microbiota using hypercholesterolemic hamsters as a model. Male golden hamsters were randomly allocated to 6 groups fed one of the following six diets， namely， low-cholesterol diet (LCD)， high-cholesterol diet (HCD)， HCD + 0.5% Tp (LTp)， HCD + 1%Tp (HTp)， HCD + 0.5%Tb (LTb)， and HCD + 1%Tb (HTb). Results showed that Tb administration at 1% could significantly reduce plasma TC， non-HDL-C， and the ratio of non-HDL-C to HDL-C， whereas Tp supplementation had no effect. Mechanistically， Tb but not Tp could decrease plasma cholesterol by increasing the excretion of fecal bile acids via upregulating gene expression of CYP7A1 and LXRα. In addition， Tb supplementation at 1% could increase the gut microbiota diversity， reduce the ratio of Firmicutes/Bacteroidetes and favorably increase the abundance of beneficial microbial genera Bifidobacterium. In conclusion， dietary Tb supplementation was more effective than Tp in mitigating hypercholesterolemia by increasing the excretion of fecal bile acids and favorably modulating gut microbiota.

CONDUCTIVITY METHOD APPLIED TO THE STUDY OFINTERACTION BETWEEN ADSORBENT AND ADSORBATE Ⅰ. ADSORPTION OF LOW CONCENTRATION OF FREE ACID BY REGENERABLE CHITIN

引用

Chinese Journal of Reactive Polymers 1997年第1期6卷 97-102页

作者： Chen Bingren He Guangping Ling Moyu wang Ruixiang Chen wensen (Department of Chemistry, South China Normal University, Guangzhou, 510631)

The adsorption of low concentration of free acid by regenerable chitin is followed by electric conductance determination. The effect of acid concentration, content of functional amino groups, and ionic strength on adsorption was discussed. Experimental results indicate that the active centre of regenerable chitin is the free amino groups on its surface, and that the rate of adsorption of free acid was found to be affected by two factors: the interaction between the adsorbent and the adsorbate in solution and that between the adsorbate molecules or ions in solution.
