| 3 | 俄罗斯贝加尔湖区伸展构造及与中国东部伸展构造对比显示文摘在晚白垩世—始新世夷平面基础上,由于断裂作用形成了贝加尔裂谷系。断裂作用最大幅度超过10km。在裂谷系中心部位发育的断层长度最大、最深、最早,并以准对称形式向四周扩展。贝加尔裂谷系是在地幔隆起和印度—欧亚大陆碰撞双重作用下形成。贝加尔裂谷系与中国东部新生代断陷盆地和汾渭裂谷系同时形成,并有密切的成因联系。它们的形成不仅受太平洋板块的俯冲和印度—欧亚大陆碰撞的制约和影响,而且位于中国西南部的地幔流发散中心,呈扇状向太平洋区流动,可能是它们在更深层次上的共同场源基础。 | 杨巍然 隋志龙 Mats VD | 2003 | 地球科学进展2003，18，1： | 12 |
| 4 | 多环芳烃污染区域氧化多环芳烃的来源、迁移转化和毒性危害显示文摘本文阐明了在对高浓度多环芳烃污染区域进行风险评估和修复过程中,氧化多环芳烃是不容忽视的重要污染物。我们通过对自己的研究成果和公开发表资料的综合分析,发现在这些地方氧化多环芳烃的量较大,但并未受到足够重视。这些氧化多环芳烃是通过多环芳烃转化而来的,滞留时间也较长。许多修复方法会加速多环芳烃的降解,从而导致在环境中的氧化多环芳烃浓度升高。此外,我们发现尽管氧化多环芳烃与通过诱变和致癌等多环芳烃常见的毒害有区别的方式产生毒性,但他们对人类和环境也是有害的。我们还有数据支持以下假说:在环境中,具有极性的氧化多环芳烃比多环芳烃稳定性差,更易通过受污染地区的地表水和地下水扩散。因此在受多环芳烃污染区域,氧化多环芳烃应该纳入监测项目当中,而其它毒性相关成分如带硝基的多环芳烃和氮杂环芳烃等则不必纳入监洲项目当中。因为氧化多环芳烃有可能在多环芳烃发生降解的时候形成,而且它们的环境行为是完全不同的,也很难通过多环芳烃浓度来预测氧化多环芳烃的含量。 | Staffan Lundstedt Paul A.White Christine L.Lemieux Krista D.Lynes Iain B.Lambert Larsberg Peter Haglund Mats Tysklind 王丽平 | 2007 | AMBIO-人类环境杂志2007，36，6： | 11 |
| 5 | Mitochondrial protection by low doses of insulin-like growth factor-Ⅰin experimental cirrhosis显示文摘AIM: To characterize the mitochondrial dysfunction in experimental cirrhosis and to study whether insulin-like growth factor-Ⅰ(IGF-Ⅰ) therapy (4 wk) is able to induce beneficial effects on damaged mitochondria leading to cellular protection. METHODS: Wistar rats were divided into three groups: Control group, untreated cirrhotic rats and cirrhotic rats treated with IGF-Ⅰtreatment (2 μg/100 g bw/d). Mitochondrial function was analyzed by flow cytometry in isolated hepatic mitochondria, caspase 3 activation was assessed by Western blot and apoptosis by TUNEL in the three experimental groups. RESULTS: Untreated cirrhotic rats showed a mitochon- drial dysfunction characterized by a significant reduction of mitochondrial membrane potential (in status 4 and 3); an increase of intramitochondrial reactive oxigen species (ROS) generation and a significant reduction of ATPase activity. IGF-Ⅰtherapy normalized mitochondrial func-tion by increasing the membrane potential and ATPase activity and reducing the intramitochondrial free radical production. Activity of the electron transport complexes Ⅰand Ⅲ was increased in both cirrhotic groups. In addition, untreated cirrhotic rats showed an increase of caspase 3 activation and apoptosis. IGF-Ⅰtherapy reduced the expression of the active peptide of caspase 3 and resulted in reduced apoptosis. | Raquel Pérez María García-Fernández Matías Díaz-Sánchez Juan E Puche Gloria Delgado Marian Conchillo Jordi Muntané Inma Castilla-Cortázar | 2008 | World Journal of Gastroenterology2008，14，17： | 11 |
| 6 | Effect of Y_2O_3 stabilized ZrO_2 coating with tri-model structure on bi-layered thermally grown oxide evolution in nano thermal barrier coating systems at elevated temperatures显示文摘Bi-layered thermally grown oxide(TGO) layer plays a major role in the spallation of Y2 O3 stabilized ZrO2(YSZ) layer form the bond coat in the thermal barrier coating(TBC) systems during oxidation. On the other hand, bi-layered TGO formation and growth in the TBC systems with nanostructured YSZ have not been deeply investigated during cyclic oxidation. Hence, Inconel 738/NiCrAlY/normal YSZ and Inconel 738/NiCrAlY/nano YSZ systems were pre-oxidized at 1000 °C and then subjected to cyclic oxidation at 1150 °C. According to microstructural observations, nanostructured YSZ layer over the bond coat should have less micro-cracks and pinholes, due to the compactness of the nanostructure and the presence of nano zones that resulted in lower O infiltration into the nanothermal barrier coating system, formation of thinner and nearly continuous mono-layered thermally grown oxide on the bond coat during pre-oxidation, lower spinels formation at the Al2 O3 /YSZ interface and finally, reduction of bi-layered thermally grown oxide thickness during cyclic oxidation. It was found that pre-heat treatment and particularly coating microstructure could influence microstructural evolution(bi-layered TGO thickness) and durability of thermal barrier coating systems during cyclic oxidation. | Mohammadreza Daroonparvar Muhamad Azizi Mat Yajid Noordin Mohd Yusof Hamid Reza Bakhsheshi-Rad Z.Valefi Esah Hamzah | 2014 | Journal of Rare Earths2014，32，1： | 10 |
| 7 | 新型PEO/纳米结构ZrO_2镁合金涂层的抗菌活性及腐蚀行为(英文)显示文摘为了增强镁合金的耐腐蚀性和抗菌活性,先采用等离子体电解氧化(PEO)在镁合金上制备一层结合层,再用空气等离子喷涂(APS)制备纳米结构ZrO_2表面涂层。采用电化学试验研究涂层样品的腐蚀行为,采用琼脂扩散法对其进行大肠杆菌病原菌抑菌活性评价,并与无涂层样品进行对比。与PEO涂层和无涂层镁合金相比,PEO/纳米ZrO_2涂层样品的腐蚀电流密度最低,电荷传递阻力最高,相位角和阻抗模量最高。PEO结合涂层被纳米ZrO_2表面涂层完全密封,能够显著延缓侵蚀性离子向镁合金表面迁移,显著提高镁合金在模拟体液(SBF)中的耐蚀性。此外,PEO/纳米ZrO_2涂层的抗菌活性也高于PEO涂层和无涂层镁合金,这是由于ZrO_2纳米颗粒通过作用于细胞膜而降低了大肠杆菌的生长速率。 | Mohammadreza DAROONPARVAR Muhamad Azizi MAT YAJID Rajeev KUMAR GUPTA Noordin MOHD YUSOF Hamid Reza BAKHSHESHI-RAD Hamidreza GHANDVAR Ehsan GHASEMI | 2018 | Transactions of Nonferrous Metals Society of China2018，28，8： | 10 |

| 9 | Investigation of three steps of hot corrosion process in Y_2O_3 stabilized ZrO_2 coatings including nano zones显示文摘Phase transformation of tetragonal ZrO2 to monoclinic phase and also increment of bond coat oxidation kinetic(TGO thickening) can substantially restrict the life time of thermal barrier coating systems(TBCs). So, nanostructured and conventional Y2O3 stabilized ZrO2 coatings were evaluated in fused V2O5-Na2SO4 salts during thermal exposure in air. Microstructural characterization showed lower hot corrosion products(monoclinic zirconia, YVO4 crystals) formation and reduction of TGO thickness in thermal barrier coating system consisting of nanostructured Y2O3 stabilized ZrO2(YSZ) top coat. It was found that inhomogeneities, pores and micro-cracks played a principal role in the molten salts infiltration into the YSZ coating during three steps of hot corrosion process. In the nanostructured YSZ coating with tri-model structure, nano zones which surrounded by fully molten parts could fill the aforementioned defects and could act as barrier for the oxygen and corrosive molten salts penetration into the TBC. | Mohammadreza Daroonparvar Muhamad Azizi Mat Yajid Noordin Mohd Yusof Hamid Reza BakhsheshiRad Esah Hamzah Mohsen Nazoktabar | 2014 | Journal of Rare Earths2014，32，10： | 10 |

| 13 | CRISPR/Cas9: Development and Application in Rice Breeding显示文摘Rice(Oryza sativa L.)is an important staple food crop worldwide due to its adaptability to different environmental conditions.Because of its great economic and social importance,there is a constant requirement for new varieties with improved agronomic characteristics,such as tolerance to different biotic(such as bacterium,fungus,insect and virus)and abiotic stresses(such as salinity,drought and temperature),higher yield and better organoleptic and nutritional value.Among the new genome editing technologies,the clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein(Cas)(CRISPR/Cas)system allows precise and specific edition in a targeted genome region.It is one of the most frequently used techniques for the study of the function of new genes and for the development of mutant lines with enhanced tolerance to biotic and abiotic stresses,herbicide resistance or improved yield.The wide varieties of applications for this technology include simple non-homologous end joining,homologous recombination,gene replacement,and base editing.In this review,we analyzed how some of these applications have been used in rice cultivars to obtain rice varieties better adapted to current environmental conditions and market requirements. | Fernando Matías ROMERO Andrés GATICA-ARIAS | 2019 | Rice science2019，26，5： | 6 |
| 14 | 瑞典森林中不同地区的林下植被情况与氮沉积的关系显示文摘在557块针叶林分中进行调查,以图了解欧洲越桔(Vaccinium myrtillus)、越桔(V.vitis-idaea)和曲芒发草(Deschampsia flexuosa)与氮沉积率的相互联系。欧洲越桔在高氮地区比在低氮地区发生频度、丰富度都较少并且易感染叶部病原(Valdensia heterodoxa),越桔的发生与氮沉积的增加呈明显的负相关,曲芒发草却没有这种趋势。在高氮沉积地区,欧洲越桔在优势种为欧洲赤松的林分中比在挪威云杉为优势种的林分中更为最普遍。在氮沉积较低水平的地区不是这种情形。调查的情况与增施氮素实验的结果一致,氮沉积对植被显示了巨大的效应。数据表明即使是较低的氮沉积也可能减少针叶林分林下植被最优势种的丰富度。 | Joachim Strengbom Mats Walheim Trogny Nsholm Lars Ericson 伍建榕 | 2003 | AMBIO-人类环境杂志2003，32，2： | 5 |

| 17 | 运用卫星数据和来自国家森林清查的野外数据进行全国森林变量估计显示文摘瑞典约有55%的土地面积被森林所覆盖。目前,瑞典的森林覆盖没有统一的和地理学上明晰的描述。现存的独立性数据源是Landsat TM和SPOT HRV卫星数据、地图蒙片(map mask)和森林清查样地。它们在一起,使森林变量(如材积和林分年龄)的计算机估计成为可能。这些估计的精确度在像素水平上是低的,但在林分水平上较高。在规划木材资源应如何加以利用或出于监测目的时,这类基于栅格的森林数据对政府来说是有帮助的。本文描述了以有效成本建立森林变量估计全国数据库的生成流程。我们在林分水平上评价了瑞典西南部某地森林变量估计的精确度。结果表明,总材积估计的整体均方根误差为33%,年龄估计的整体均方根误差为23%。 | Heather Reese Mats Nilsson Tina Granqvist Pahlén Olle Hagner Steve Joyce Ulf Tingelf Mikael Egberth Hkan Olsson 王胜 | 2003 | AMBIO-人类环境杂志2003，32，8： | 4 |

| 19 | Asymmetric photocurrent extraction in semitransparent laminated flexible organic solar cells显示文摘Scalable production methods and low-cost materials with low embodied energy are key to success for organic solar cells.PEDOT(PSS)electrodes meet these criteria and allow for low-cost and all solution-processed solar cells.However,such devices are prone to shunting.In this work we introduce a roll-to-roll lamination method to construct semitransparent solar cells with a PEDOT(PSS)anode and an polyethyleneimine(PEI)modified PEDOT(PSS)cathode.We use the polymer:PCBM active layer coated on the electrodes as the lamination adhesive.Our lamination method efficiently eliminates any shunting.Extended exposure to ambient degrades the laminated devices,which manifests in a significantly reduced photocurrent extraction when the device is illuminated through the anode,despite the fact that the PEDOT(PSS)electrodes are optically equivalent.We show that degradation-induced electron traps lead to increased trap-assisted recombination at the anode side of the device.By limiting the exposure time to ambient during production,degradation is significantly reduced.We show that lamination using the active layer as the adhesive can result in device performance equal to that of conventional sequential coating. | Jonas Bergqvist Thomas Osterberg Armantas Melianas Luis Ever Aguirre Zheng Tang Wanzhu Cai Zaifei Ma Martijn Kemerink Desta Gedefaw Mats R.Andersson Olle InganAs | 2018 | npj Flexible Electronics2018，2，1： | 4 |
| 20 | Genetic barriers in transplantation medicine显示文摘The successful of transplantation is determined by the shared human leukocyte antigens(HLAs) and ABO blood group antigens between donor and recipient. In recent years, killer cell receptor [i.e., killer cell immunoglobulinlike receptor(KIR)] and major histocompatibility complex(MHC) class I chain-related gene molecule(i.e., MICA) were also reported as important determinants of transplant compatibility. At present, several different genotyping techniques(e.g., sequence specific primer and sequence based typing) can be used to characterize blood group, HLA, MICA and KIR and loci. These molecular techniques have several advantages because they do not depend on the availability of anti-sera, cellular expression and have greater specificity and accuracy compared with the antibody-antigen based typing. Nonetheless, these molecular techniques have limited capability to capture increasing number of markers which have been demonstrated to determine donor and recipient compatibility. It is now possible to genotype multiple markers and to the extent of a complete sequencing of the human genome using next generation sequencer(NGS). This high throughput genotyping platform has been tested for HLA, and it is expected that NGS will be used to simultaneously genotype a large number of clinically relevant transplantation genes in near future. This is not far from reality due to the bioinformatics support given by the immunogenetics community and the rigorous improvement in NGS methodology. In addition, new developments in immune tolerance based therapy, donor recruitment strategies and bioengineering are expected to provide significant advances in the field of transplantation medicine. | Hisham A Edinur Siti M Manaf Nor F Che Mat | 2016 | World Journal of Transplantation2016，6，3： | 4 |
