| 1 | 人参潜在地理分布以及气候变化对其影响预测显示文摘本文以人参为研究对象,基于人参分布点位数据和22个气候环境因子数据,运用BioMod2平台10个物种分布模型对当前我国东北地区人参潜在生境分布进行预测.以受试者工作特征曲线(ROC)为权重集成10个模型的模拟结果,构建组合模型,并基于该模型预测了IPCC第五次评估报告中RCP 8.5、RCP 6.0、RCP 4.5和RCP 2.6等4种排放情景下21世纪50和70年代人参潜在分布范围.结果表明:在基准气候条件下,人参适宜生境面积占研究区总面积的10.4%,此类地区主要分布于研究区东北部长白山地区以及小兴安岭东南部区域的森林地带.在未来不同的排放情景下研究区人参的适宜生境变化显著,总体上分布范围将有一定程度的缩小.同时参与建模的10种模型在统计学精度、预测结果以及变量权重上都有差异.模型精度计算结果表明,MAXENT模拟效果最好,GAM、RF和ANN次之,SRE模拟精度最低.本文构建的组合模型在一定程度上提高了现有物种分布模型的预测精度,从而使模拟效果更优. | 赵泽芳 卫海燕 郭彦龙 顾蔚 | 2016 | 应用生态学报2016,27,11: | 36 |
| 2 | 基于PacBio平台的全长转录组测序显示文摘当前,绝大多数的转录组数据都是基于以Illumina平台为代表的第二代高通量测序技术获得的,但是第二代测序技术无法提供大量的长转录本并且丢失可变剪接等重要信息,因而大大制约了转录组数据的深度利用.通过以PacBio为代表的第三代测序技术,可以获得更长乃至全长转录组,但由于Pac Bio转录组测序近几年才刚兴起,只有少量的物种基于PacBio平台获得了转录组.PacBio全长转录组测序,在国际上才刚开展但发展很快,其实验与数据分析标准和质量控制方面的研究对于未来的大规模应用至关重要.本研究在国际上首次尝试依据PacBio平台最新试剂(P6/C4)优化实验参数,设计质量控制指标并使全长转录组测序标准化.本文基于一组昆虫(麻皮椿)全长转录组数据,对已取得的部分结果进行报告. | 任毅鹏 张佳庆 孙瑜 吴振峰 阮吉寿 贺秉军 刘国卿 高山 卜文俊 | 2016 | 科学通报2016,61,11: | 17 |

| 5 | Cryogenic Thermophysical Studies for Clinical Medicine显示文摘Cryogenic technology has been widely used in clinical medicine and in pharmaceutics, so thermophysical studies are extremely important to solve problems during freezing and thawing. This paper reports some recent research in clinical medicine, including cryo injury, cryosurgery, and cryopreservation of some important cells and tissues. Microscopic images of the freezing process with a cryomicroscope system show that the dendritic ice growth is affected by the solution concentration, the cooling rate, and the number of embryos. An enthalpy method is used for the freeze thaw analysis of the cryosurgery with a program developed to predict the temperature profile and the interface motion, which compares well with experimental results. A very rapid cooling technique is developed by quenching the samples into subcooled liquid nitrogen for vitrification of cells and tissues. An analytical method developed to prevent the fracture of arteries during freezing has been verified by the electronic microscopic investigation. | 华泽钊 | 2002 | Tsinghua Science and Technology2002,7,2: | 8 |
| 6 | 基于SMRT测序技术的16S rRNA基因全长测序及其分析方法显示文摘被称为第三代测序技术的单分子测序是最近几年发展起来的高通量测序技术。其中,由Pacbio Bio Sciences公司开发的单分子实时测序技术(SMRT)是最先商用的技术。SMRT测序技术通过对模板序列循环测序产生环形一致序列(CCS),成功克服第三代测序技术准确率低的弊病。通过SMRT测序技术,科学家可以更深入准确地探究复杂环境微生物的结构和功能。介绍SMRT测序技术在微生物16S rRNA基因测序中的优势和劣势,并就基于SMRT测序技术所得的全长16S rRNA基因序列的质量控制、错误序列排除、聚类和注释分析等重要分析环节进行概述,同时,提出利用SMRT测序技术研究复杂环境微生物可能存在的问题及其解决方法,期望能为研究人员提供参考。 | 唐勇 刘旭 | 2017 | 生物技术通报2017,33,8: | 8 |
| 7 | 模型及ChemBioOffice在有机化学实验中的应用显示文摘有机化学是药学专业非常重要又较难学习的一门专业基础课,认识有机化合物的结构是学好这门课程的基础,单纯平面教学无法深入地将分子的实际空间结构加以充分展示。通过在有机化学实验课中开设球棍模型搭建及Chem Bio Office软件应用这一内容,利用立体、形象的原子间的相对位置,可以促进学生迅速地理解、掌握化合物的立体结构,把握有机分子构成的基本方式,为后续的教学内容打下良好的基础。 | 陈莉敏 林友文 王津 | 2014 | 广州化工2014,42,21: | 4 |
| 8 | Overview of In—Situ Biodegradation and Enhancement显示文摘Microbial degradation technologies have been developed to restore ground water quality in aquifers polluted by organic contaminants effectively in recent years. However, in course of the degradation, the formation of biofilms in ground water remediation technology can be detrimental to the effectiveness of a ground water remediation project. Several alternatives are available to a remedial design engineer, such as Permeable Reactive Barriers (PRBs) and in -situ bioremediation, Hydrogen Releasing Compounds (HRCs) barrier, Oxygen Releasing Compounds (ORCs) barrier etc. which are efficient and cost- effective technologies. Excessive biomass formation renders a barrier ineffective in degrading the contaminants, Efforts are made to develop kinetics models which accurately determine bio - fouling and bio - filn formation and to control excessive biomass formation. | DONG Jun, Anthony ADZOMANI and ZHAO Yongsheng(College of Environment and Resources, Jilin University, Changchun 130026, P.

| 9 | Biological therapy in inflammatory bowel diseases:Access in Central and Eastern Europe显示文摘Biological drugs opened up new horizons in the management of inflammatory bowel diseases(IBD).This study focuses on access to biological therapy in IBD patients across 9 selected Central and Eastern European(CEE)countries,namely Bulgaria,the Czech Republic,Estonia,Hungary,Latvia,Lithuania,Poland,Romania and Slovakia.Literature data on the epidemiology and disease burden of IBD in CEE countries was systematically reviewed.Moreover,we provide an estimation on prevalence of IBD as well as biological treatment rates.In all countries with the exception of Romania,lower biological treatment rates were observed in ulcerative colitis(UC)compared to Crohn’s disease despite the higher prevalence of UC.Great heterogeneity(up to 96-fold)was found in access to biologicals across the CEE countries.Poland,Bulgaria,Romania and the Baltic States are lagging behind Hungary,Slovakia and the Czech Republic in their access to biologicals.Variations of reimbursement policy may be one of the factors explaining the differences to a certain extent in Bulgaria,Latvia,Lithuania,and Poland,but association with other possible determinants(differences in prevalence and incidence,price of biologicals,total expenditure on health,geographical access,and cost-effectiveness results)was not proven.We assume,nevertheless,that healthdeterioration linked to IBD might be valued differently against other systemic inflammatory conditions in distinct countries and which may contribute to the immense diversity in the utilization of biological drugs for IBD.In conclusion,access to biologicals varies widely among CEE countries and this difference cannot be explained by epidemiological factors,drug prices or total health expenditure.Changes in reimbursement policy could contribute to better access to biologicals in some countries. | Fanni Rencz Márta Péntek Martin Bortlik Edyta Zagorowicz Tibor Hlavaty Andrzej Sliwczyński Mihai M Diculescu Limas Kupcinskas Krisztina B Gecse László Gulácsi Peter L Lakatos | 2015 | World Journal of Gastroenterology2015,21,6: | 4 |

| 11 | Carbon nanotubes:Evaluation of toxicity at biointerfaces显示文摘Carbon nanotubes (CNTs) are a class of carbon allotropes with interesting properties that make them productive materials for usage in various disciplines of nanotechnology such as in electronics equipments, optics and therapeutics. They exhibit distinguished properties viz., strength, and high electrical and heat conductivity. Their uniqueness can be attributed due to the bonding pattern present between the atoms which are very strong and also exhibit high extreme aspect ratios. CNTs are classified as singlewalled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) on the basis of number of sidewalls present and the way they are arranged spatially. Application of CNTs to improve the performance of many products, especially in healthcare, has led to an occupational and public exposure to these nanomaterials. Hence, it becomes a major concern to analyze the issues pertaining to the toxicity of CNTs and find the best suitable ways to counter those challenges. This review summarizes the toxicity issues of CNTs in vitro and in vivo in different organ systems (bio interphases) of the body that result in cellular toxicity. | Debashish Mohanta Soma Patnaik Sanchit Sood Nilanjan Das | 2019 | Journal of Pharmaceutical Analysis2019,9,5: | 4 |

| 16 | 一种新结构的DM-multipath与动态负载平衡显示文摘对于存储设备,Linux在多路径I/O方面主要有两种类型的解决方案:位于I/O调度器之上的顶层方案(BIO映射器)和位于底层的子系统具体方案(如IDE,SCSI)。因为实施它们的所在存储堆栈中的位置不同,每种方案各有优势。通过与第一种方案比较,介绍具体硬件子系统之上的另一种解决方案,新结构中重点实现移动内核当前多路径层——多路径设备映射器(dm-multipath)到I/O调度层之下,这种方案能够有效地支持动态的负载平衡。 | 阚闯 戚玮玮 | 2008 | 计算机应用2008,28,2: | 2 |
| 17 | Citric acid-assisted synthesis of nano-Ag/BiO Br with enhanced photocatalytic activity显示文摘In this study, silver nano-particles have been anchored in the surface of Bi OBr photocatalysts by a citric acid-assisted photoreduction method. The citric acid was served as a chelating and reductive agent for the preparation of Ag-decorated Bi OBr photocatalysts(named as Ag/Bi OBr-2). The as-synthesized samples were characterized by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), scanning electron microscopy(SEM), transmission electron microscopy(TEM), and UV-Vis diffuse reflection spectroscopy(DRS). The Ag/Bi OBr-2 photocatalyst exhibited excellent and stable photocatalytic activities on MO and phenol degradation under simulated sunlight irradiation. The enhanced photocatalytic activity could be ascribed to the smaller size, rough surface, and the surface plasma resonance(SPR) effect of Ag. Also, the Schottky junction, between the surface of the Bi OBr and silver nanoparticles, accelerated the efficient transfer and separation of photoinduced electron-hole pairs and promoted the photocatalytic performance. The active species tests indicated that the superoxide radical(·O-2) was responsible for the enhanced photocatalytic performance of Ag/Bi OBr-2. Finally, a possible photocatalytic mechanism was proposed. | Xiuli Li Xiaoming Mao Xiaochao Zhang Yunfang Wang Yawen Wang Hui Zhang Xiaogang Hao Caimei Fan | 2015 | Science China Chemistry2015,58,3: | 2 |
