| 1 | Genetically humanized pigs exclusively expressing human insulin are generated through custom endonuclease-mediated seamless engineering显示文摘Dear Editor,Type1diabetes(T1D)isa lifelong(chronic)disease and a major health problem throughout the world.This disease can be treatedby either insulin injection or islet transplantation.Islet transplantation is considered as a better treatment for T1D patients,because islets can produce and release insulin at the appropriate time,resulting in tight blood glucose control. | Yi Yang Kepin Wang Han Wu Qin Jin Degong Ruan Zhen Ouyang Bentian Zhao Zhaoming Liu Yu Zhao Quanjun Zhang Nana Fan Qishuai Liu Shimei Guo Lei Bu Yong Fan Xiaofang Sun Xiaoping Li Liangxue Lai | 2016 | Journal of Molecular Cell Biology2016，8，2： | 6 |
| 2 | Fabrication of superstable gold nanorod-carbon nanocapsule as a molecule loading material显示文摘In this work, we fabricated a monodisperse nanocomposite by coating gold nanorods(Au NRs) with a layer of biocompatible, stable carbon, obtaining Au NR@Carbon core–shell nanocapsules, which without any functionalization could be used as a molecule loading material due to its high surface areas. In this system, the Au NR core had a high-absorption cross section for conversion of near-infrared light to heat, which could be explored for local hyperthermia. The carbon shell, which was biocompatible and stable even under concentrated acidic and alkaline conditions, was able to adsorb molecules with p–p interactions or electrostatic interactions. In comparison with Au NR@Si O2, Au NR@Carbon nanocapsules demonstrate the following merits:(1) simple and green synthesis method,(2) far more stable with respect to high-temperature stability and(3) larger molecule loading capacity,which indicate great potential in the biomedical applications. | Wei Gao Xuewei Wang Huanhuan Fan Zhiling Song Xiaofang Lai Zhuo Chen Weihong Tan | 2015 | Science Bulletin2015，60，12： | 3 |
| 3 | Stable and unique graphitic Raman internal standard nanocapsules for surface-enhanced Raman spectroscopy quantitative analysis显示文摘Graphitic nanomaterials 有的独特、强壮、稳定的拉曼颤动广泛地在化学和 biomedicine 被使用了。然而,作为内部标准(ISs ) 利用他们改进提高表面的拉曼的精确性光谱学(重量的单位) 分析没被尝试。此处,我们报导设计一唯一是由很多金牌组成的 nanostructure nanoparticles (AuNPs ) 在 multilayered graphitic 上装饰了磁性的 nanocapsules (AGN ) 确定 analyte 并且消除与传统的 ISs 联系的问题。AGN 从 graphitic 部件表明了一个独特拉曼乐队,它在拉曼是局部性的 biomolecules 的沉默区域,没有任何背景干扰,使他们成为理想为量的拉曼分析。是从也显示的 AGN 的信号优异稳定性,甚至在严厉条件下面。与装饰 AuNPs 的改进, AGN nanostructures 极大地改进了重量的单位,特别地量的错误源于收集损失的排除和 analytes 的不一致的分发的量的精确性。AGN 进一步为房间染色和拉曼成像被利用,并且他们在 biomedicine 为应用显示出大诺言。 | Yuxiu Zou Long Chen Zhiling Song Ding Ding Yiqin Chen Yiting Xu Shanshan Wang Xiaofang Lai Yin Zhang Yang Sun Zhuo Chen Weihong Tan | 2016 | Nano Research2016，9，5： | 2 |
| 4 | miR-103-3p regulates the differentiation of bone marrow mesenchymal stem cells in myelodysplastic syndrome显示文摘The pathogenesis of myelodysplastic syndrome(MDS)may be related to the abnormal expression of microRNAs(miRNAs),which could influence the differentiation capacity of mesenchymal stem cells(MSCs)towards adipogenic and osteogenic lineages.In this study,exosomes from bone marrow plasma were successfully extracted and identified.Assessment of miR-103-3p expression in exosomes isolated from BM in 34 MDS patients and 10 controls revealed its 0.52-fold downregulation in patients with MDS compared with controls(NOR)and was downregulated 0.55-fold in MDS-MSCs compared with NOR-MSCs.Transfection of MDS-MSCs with the miR-103-3p mimic improved osteogenic differentiation and decreased adipogenic differentiation in vitro,while inhibition of miR-103-3p showed the opposite results in NOR-MSCs.Thus,the expression of miR-103-3p decreases in MDS BM plasma and MDS-MSCs,significantly impacting MDS-MSCs differentiation.The miR-103-3p mimics may boost MDS-MSCs osteogenic differentiation while weakening lipid differentiation,thereby providing possible target for the treatment of MDS pathogenesis. | NINGYU LI XIAOFANG CHEN SUXIA GENG PEILONG LAI LISI HUANG MINMING LI XIN HUANG CHENGXIN DENG YULIAN WANG JIANYU WENG XIN DU | 2023 | BIOCELL2023，47，1： | 0 |
| 5 | Density Functional Theoretical Study of 5 ,5 '-Azotetrazolate Nonmetallic Salts显示文摘The structures, infrared spectra and cation stability of seven 5,5′-azotetrazolate nonmetallic salts are investigated by using B3LYP method with 6-311+G (d) basis set. The salts are guanidinium (GZT), aminoguanidinium (AGZT), diaminoguanidinium (DAGZT), triaminoguanidinium (TAGZT), azidoformamidinium (AFZT), ammonium (AZT), and hydrazinium (HZT), respectively. The calculated results indicate that the carbon and nitrogen atoms of the cations in seven nonmetallic salts are characterized to be sp2 hybrid atoms, and the ranges of characteristic absorption peaks in IR spectra of the seven nonmetallic salts are approximative consistent. All their cations are stable and their stabilities decrease with the increase in their nitrogen contents. | LAI Weipeng GE Zhongxue LIAN Peng YU Tao CHEN Xiaofang QIU Shaojun WANG Bozhou | 2013 | Defence Technology(防务技术)2013，9，2： | 0 |
| 6 | Development of a Detection Method for Assaying Calf Intestine Alkaline Phosphatase Activity显示文摘[Objective]This study was to develop a detection method for assaying calf intestine alkaline phosphatase activity in scientific research. [Method]By simulating the conditions and buffers for assaying calf intestine alkaline phosphatase used in the scientific research,the parameters influencing substrate concentration,reaction duration,coloration time and buffer p H were optimized. [Result]The activity of alkaline phosphatase detected varied hugely among different buffers,and potassium ferricyanide solution added with boracic acid achieved the stable coloration. The optimal water bath time was determined as 10 min,and the substrate concentration was optimized as 0. 04 mol / L. The increasing temperature did not have a large influence on low temperature enzymatic activity while did on high concentration enzymatic activity. When the buffer p H was 7. 0- 8. 0,the detection stability of alkaline phosphatase could be maintained well. The ion intensity of buffer had little effects on alkaline phosphatase activity. [Conclusion]A detection method for assaying calf intestine alkaline phosphatase activity in scientific research was successfully developed in this study. | Lin Lin Lai Xiaofang Li Yi Liu Yixiong Lan Quanxue Lai Xintian Yang Guowu | 2015 | Animal Husbandry and Feed Science2015，7，3： | 0 |
