| 1 | Studies on the spray dried lactose as carrier for dry powder inhalation显示文摘The purpose of this study was to investigate the spray dried lactose as carrier for dry powder inhalation(DPI).The lactose particles were prepared by spray drying,then the particle size,shape and crystal form were characterized by laser diffraction,scanning electron microscopy(SEM),X-ray diffraction(XRD)and differential scanning calorimetry(DSC).The spray dried lactose particles were spherical and amorphous,but would transfer to crystal form when storage humidity was above 32%.Thus,the humidity of the storage environment should be controlled below 30%strictly in order to maintain the amorphous nature of spray dried lactose which is a great benefit to DPI development. | Linna Wu Xu Miao Ziyun Shan Ying Huang Lu Li Xin Pan Qinghe Yao Ge Li Chuanbin Wu | 2014 | Asian Journal of Pharmaceutical Sciences2014，9，6： | 1 |
| 2 | A preliminary investigation into critical thinking of urban Xi'an high school students显示文摘本文是对中国西安市城镇高中生批判性思维的调查。通过应用《加利福尼亚批判性思维倾向问卷》和《加利福尼亚批判性思维技能测验》测查发现:高中生在批判性思维倾向上总体处于中等水平;在批判性思维技能上总体水平较低;文科生与理科生在批判性思维倾向上没有显著差异,而在批判性思维技能上有显著差异;重点班学生与非重点班学生在批判性思维倾向和技能上均有显著差异;男生与女生在批判性思维倾向和技能上没有显著差异。 | ZHOU Qing WANG Xiang YAO Linna | 2007 | Frontiers of Education in China2007，2，3： | 0 |
| 3 | Isoliquiritigenin inhibits Ishikawa endometrial carcinoma cells proliferation and promotes apoptosis显示文摘Endometrial cancer is the fourth most frequent neoplasia i women worldwide,and the molecular mechanisms involved in the etiology and pathogenesis continue to be investigated.Isoliquiritigenin(ISL),an important flavonoid isolated from Glycyrrhizae radix,possesses a wide range of pharmacological properties such as antioxidant,antiinflammatory,antitumor and immunoreg ulatory activities.This study aimed to investigate the molecular mechanisms of ISL on the proliferation and apoptosis resistance of Ishikawa endometrial carcinoma cells. | Yao Lijie Jiang Yang Ma Yong Guo Linna Jin Haifeng | 2021 | 解剖学杂志2021，44，S01： | 0 |
| 4 | Separation of cortical arteries and veins in optical neurovascular imaging显示文摘Separation of arteries and veins in the cerebral cortex is of significant importance in the studies of cortical hemodynamics,such as the changes of cerebral blood flow,perfusion or oxygen con-centration in arteries and veins under different pathological and physiological conditions.Yet the cerebral vessel segmentation and vessel-type separation are challenging due to the complexity of cortical vessel characteristics and low spatial signal-to-noise ratio.In this work,we presented an effective full-field method to differentiate arteries and veins in cerebral cortex using dual-modal optical imaging technology including laser speckle imaging(LSI)and optical intrinsic signals(OIS)imaging.The raw contrast images were acquired by LSI and processed with enhanced laser speckle contrast analysis(eLASCA),algorithm.The vascular pattern was extracted and seg-mented using region growing algorithm from the eLASCA-based LSI.Meanwhile,OIS imageswere acquired altermatively with 630 and 870 nm to obtain an oxy hemoglobin concentration mapover cerebral cortex.Then the separation of arteries and veins was accomplished by Otsuthreshold segmentation algorithm based on the OIS information and segmentation of LSI.Finally,the segmentation and separation performances were assessed using area overlap measure(AOM).The segmentation and separation of cerebral vessels in cortical optical imaging have great potential applications in full-field cerebral hemodynamics monitoring and pathological study of cerebral vascular diseases,as well as in clinical intraoperative monitoring. | Linna Zhao Yao Li Hongyang Lu Lu Yuan Shanbao Tong | 2014 | Journal of Innovative Optical Health Sciences2014，7，3： | 0 |
| 5 | 锂氧电池中基于自支撑Ag/δ-MnO_(2)纳米花正极的可逆LiOH化学显示文摘因放电产物对有机电解液具有高攻击性,使得锂-氧电池能量效率低和循环稳定性差的问题一直限制着其实际应用.与典型放电产物过氧化锂相比,氢氧化锂(LiOH)具有更好的化学和电化学稳定性.本文通过在碳纸上原位生长嵌有纳米银的花状二氧化锰作为锂-氧电池的正极(Ag/δ-MnO_(2)@CP),并证明了它能催化LiOH的可逆生成和分解.原位拉曼测试和理论计算表明Ag/δ-MnO_(2)催化放电中间体LiO2*与水分子解离的H+反应最终生成LiOH.以Ag/δ-MnO_(2)@CP为正极的锂-氧电池在潮湿氧气环境下表现出更高的比容量和放电平台.在电流密度为200 mA g^(−1)时,锂-氧电池的过电位仅为0.5 V,在500 mA h g^(−1)的限制比容量下可循环867圈.该工作为研究固相催化剂在锂-氧电池中的作用提供了新的思路,并将促进基于LiOH放电产物的锂-氧电池的实际应用. | Linna Dai Qing Sun Yuqing Yao Huanhuan Guo Xiangkun Nie Jianwei Li Pengchao Si Jingyu Lu Deping Li Lijie Ci | 2022 | Science China Materials2022，65，6： | 0 |
