| 1 | 一氧化氮在神经退行性疾病中的作用:非类固醇性抗炎药的治疗前景(英文)显示文摘一氧化氮(nitric oxide, NO)是一类胞内信使。研究表明,神经退行性病人脑组织中催化合成NO的酶的表达水平显著提高,提示NO与神经退行性疾病密切相关。此外,在这些组织中还检测到硝化的蛋白,提示NO在这些组织中具有生物活性。在神经免疫应答中,神经元和胶质细胞(包括小胶质细胞和星形胶质细胞)内都发生了NO水平的改变。很多神经退行性疾病都伴随有神经炎症,抑制神经炎症的信号通路能延迟这些疾病的发展。因此,NO及其释放通路已逐渐成为神经退行性疾病研究领域的热点,对它们的理解能帮助我们找到合适的方案来预防、减缓或者治愈这些疾病。 | Gayle Helane Doherty | 2011 | Neuroscience Bulletin2011，27，6： | 4 |

| 3 | Synthesis of LiSm_(0.01)Mn_(1.99)O_4 by molten salt technique显示文摘Samarium substituted lithium manganese oxide powders were successfully prepared by molten-salt synthesis(MSS) using eutectic mixture of LiCl,SmCl3.6H2O and MnO2 salt at 700 °C.The synthesis was carried out in open atmosphere.The crystalline powders were characterized for their phase identification using X-ray diffraction(XRD) analysis.The physico-chemical properties of the samarium substituted lithium manganese oxide powders were investigated by thermal analysis(TGA/DTA),FT-IR spectroscopy,EDAX,electron paramagnetic resonance spectroscopy(EPR) and scanning electron microscopy(SEM).This investigation showed the possible methodology for obtaining pure LiSm0.01Mn1.99O4 at low temperature. | M Helan L John Berchmans | 2010 | Journal of Rare Earths2010，28，2： | 2 |
| 4 | Unsupervised Nonlinear Adaptive Manifold Learning for Global and Local Information显示文摘In this paper,we propose an Unsupervised Nonlinear Adaptive Manifold Learning method(UNAML)that considers both global and local information.In this approach,we apply unlabeled training samples to study nonlinear manifold features,while considering global pairwise distances and maintaining local topology structure.Our method aims at minimizing global pairwise data distance errors as well as local structural errors.In order to enable our UNAML to be more efficient and to extract manifold features from the external source of new data,we add a feature approximate error that can be used to learn a linear extractor.Also,we add a feature approximate error that can be used to learn a linear extractor.In addition,we use a method of adaptive neighbor selection to calculate local structural errors.This paper uses the kernel matrix method to optimize the original algorithm.Our algorithm proves to be more effective when compared with the experimental results of other feature extraction methods on real face-data sets and object data sets. | Jiajun Gao Fanzhang Li Bangjun Wang Helan Liang | 2021 | Tsinghua Science and Technology2021，26，2： | 2 |

| 18 | A novel breathable flexible metallized fabric for wearable heating device with flame-retardant and antibacterial properties显示文摘Currently,there is an imperative demand for developing a novel flexible heater with high adhesion,breathability,and extreme condition resistance,such as ultra-high temperatures and even fire.Herein,a high-adhesion,flame-retardancy,and anti-bacteria copper nanoparticles networks/nylon 6 woven fabric(CNNs/NWF)wearable heater with a“sandwich-like”structure has been designed and fabricated based on phatic acid/aminopropyltriethoxysilane(PA/APTES)hybrid coating.On the one hand,the CNNs/NWF wearable heater exhibited superb electrothermal behavior working at a peak temperature of 208.8℃powered with 2.0 V,better than that of wearable heaters in the recently reported literature.On the other hand,the vertical burning test showed that the heater possesses splendid flame retardancy.Furthermore,the PA/APTES coating could deposit a nanoscale porous protective film on the surface of CNNs/NWF,which imparts the heater with relatively excellent oxidation resistance and breathability.In addition,the antibacterial efficiency against Escherichia coli(E.coli)and Staphylococcus aureus(S.aureus)still reached100%after 50 times of standard washing and being electrified at 2.0 V for 5 min,keeping humans away from the threat of bacterial infections.We think that the heater in this research could be extended to wearable heating devices. | Peibo Du Jinping Zhang Zhiguang Guo Helan Wang Zhenmeng Luo Zhiying Fan Bo Li Zaisheng Cai Fengyan Ge | 2022 | Journal of Materials Science & Technology2022，，27： | 1 |
