5Intratumoral dendritic cell vaccin ation elicits potent tumoricidal im munity against malignant glioma in rats显示文摘Dendritic cells(DC)are attractive candidates for innovative cancer immunotherapy by virtu e of their ability to function as powe rful antigen presenting cells and elicit potent antitumor cytotoxic immune r esponses.With the aim of generating antitumor immunity,the authors sought to enhance in vivo tum or antigen presentation by using an i ntratumoral DC vaccination strateg y in the setting of partially irradiated intracranial brain tumo rs.Fisher rats,implanted with 9L gliomas in the right corpus striatum,w ere treated with freshly cultured,unpulsed syngeneic DC inoculated directly into the tumor bed.Intracranially inoculated DCs were found to drain to ipsilateral deep cervical lymph nodes.This was a ssociated with increased local and s ystemic antitumor cytoxicity,as evidenced by robust infiltration of treated tumors with CD4and CD8T ce lls as well as by increased IFN-gamma protein and message levels in in vitr o restimulated splenic lymphocytes.DC therapy resulted in prolonged survival and immunity to s ubsequent intracranial tumor re-ch allenge.These results demonstrate the viability of intratumoral DC vaccination as an effectiv e therapeutic strategy for intracra nial glioma.Ehtesham M Kabos P Gutierrez MA Samoto K Black KL Yu JS 2003癌症2003,22,7:8
6大塑性变形6013铝合金的时效特性与力学性能(英文)显示文摘利用X射线衍射分析(XRD)、差示扫描量热法(DSC)和拉伸试验,研究不同温度等通道转角挤压(ECAP)和常规静态时效处理后6013 Al-Mg-Si铝合金的微观结构、时效行为、析出动力学以及力学性能。XRD测得的ECAP变形后合金的平均晶粒尺寸在66-112 nm范围内,平均位错密度在1.20×10^14-1.70×10^14 m^-2范围内。DSC分析表明,由于ECAP后试样比常规时效处理试样拥有更细小的晶粒和更高的位错密度,因此,ECAP变形后合金的析出动力学更快。与未变形合金相比,ECAP后试样的屈服强度和抗拉强度都得到了显著提高。室温ECAP后试样的强度达到最大,其屈服强度是静态峰时效屈服强度的1.6倍。细晶强化、位错强化以及由于ECAP过程中的动态析出而产生的析出相强化,是ECAP合金获得高强度的几种主要强化机制。刘满平 蒋婷慧 王俊 刘强 吴振杰 Ying-da YU Pl C.SKARET Hans J.ROVEN 2014Transactions of Nonferrous Metals Society of China2014,24,12:8
7Role of stem cell therapies in treating chronic wounds:A systematic review显示文摘BACKGROUND The impairment of cutaneous wound healing results in chronic,non-healing wounds that are caused by altered wound environment oxygenation,tissue injury,and permissive microbial growth.Current modalities for the treatment of these wounds inadequately address the complex changes involved in chronic wound pathogenesis.Consequently,stem cell therapies have emerged as a potential therapeutic modality to promote cutaneous regeneration through trophic and paracrine activity.AIM To investigate current literature regarding use of stem cell therapies for the clinical treatment of chronic,non-healing wounds.METHODS PubMed,EMBASE,Cochrane Library,Web of Science,and Scopus were queried with combinations of the search terms“mesenchymal stem cells,”“adult stem cells,”“embryonic stem cells,”“erythroid precursor cells,”“stem cell therapies,”and“chronic wounds”in order to find relevant articles published between the years of 2000 and 2019 to review a 20-year experience.Reference lists from the articles were reviewed to identify additional pertinent articles.Retrieved manuscripts(reviews,case reports/series,retrospective/prospective studies,and clinical trials)were evaluated by the authors for their depiction of clinical stem cell therapy use.Data were extracted from the articles using a standardized collection tool.RESULTS A total of 43 articles describing the use of stem cell therapies for the treatment of chronic wounds were included in this review.While stem cell therapies have been explored in in vitro and in vivo applications in the past,recent efforts are geared towards assessing their clinical role.A review of the literature revealed that adipose-derived stem cells,bone marrow-derived stem cells,bone marrowderived mononuclear cells,epidermally-derived mesenchymal stem cells,fibroblast stem cells,keratinocyte stem cells,placental mesenchymal stem cells,and umbilical cord mesenchymal stem cells have all been employed in the treatment of chronic wounds of various etiologies.Most recently,embryonic stem cells have emerged as a novel stem cell therapy with the capacity for multifaceted germ cell layer differentiation.With the capacity for self-renewal and differentiation,stem cells can enrich existing cell populations in chronic wounds in order to overcome barriers impeding the progression of wound healing.Further,stem cell therapies can be utilized to augment cell engraftment,signaling and activity,and resultant patient outcomes.CONCLUSION Assessing observed clinical outcomes,potential for stem cell use,and relevant therapeutic challenges allows wound care stakeholders to make informed decisions regarding optimal treatment approaches for their patients’chronic wounds.Anjali C Raghuram Roy P Yu Andrea Y Lo Cynthia J Sung Melissa Bircan Holly J Thompson Alex K Wong 2020World Journal of Stem Cells2020,12,7:5
8帕劳国预应力连续箱梁长期下挠分析显示文摘帕劳共和国科罗尔岛-巴伦尔图阿普岛桥(简称KB桥)为主跨241 m的预应力混凝土箱梁,通车后KB桥发生长期下挠,严重影响其正常运营,最后垮塌,其教训值得反思。该桥于1977竣工,运营18年后挠度达到1.61 m,1996年对该桥进行了体外预应力加固,却在加固后3个月发生垮塌。挠度分析结果表明:传统的梁理论与三维空间分析相比,误差高达20%,且宽跨比越大,误差越大。三维有限元空间分析采用多种徐变收缩计算模型:美国ACI模型、日本JSCE模型、CEB-FIP模型和GL模型,其挠度计算值要比(18年后)实测值低50%~70%,预测的变形也与实测不符;预应力损失计算值为22%~24%,远低于实测值50%。唯一基于理论的B3模型,采用经验值参数计算得到预应力损失40%,18年后挠度计算值比实测值低42%。如果根据长期实测值调整输入参数,结果可与实际更符合。对于早期挠度及其预测,B3模型能够合理地考虑因截面厚度差异产生的收缩和干燥徐变的速率差异。此外,B3模型还可考虑温度差异和顶板可能发生的开裂。叶华文 王力武 曲浩博 Bazant Z P Yu Q Li G H 2017中外公路2017,37,5:5
9Human Immunodeficiency Virus Infection-Associated Mortality during Pulmonary Tuberculosis Treatment in Six Provinces of China显示文摘Objective To investigate the risk factors attributable to tuberculosis-related deaths in areas with human immunodeficiency virus(HIV) infection epidemics. Methods A prospective cohort study of newly registered patients in tuberculosis(TB) dispensaries in six representative Chinese provinces was conducted from September 1, 2009 to August 31, 2011. Risk factors for TB-associated death were identified through logistic regression analysis. Results Of 19,103 newly registered pulmonary TB patients, 925(4.8%) were found to be HIV-positive. Miliary TB and acid-fast bacillus smear-negative TB were more common among these patients. Out of a total of 322(1.7%) deaths that occurred during TB treatment, 85(26%) of the patients were co-infected with HIV. Multivariate analysis revealed that HIV infection was the strongest predictor of death [adjusted odds ratio(aO R) 7.86]. Other significant mortality risk factors included presentation with miliary TB(aO R 4.10; 95% confidence interval: 2.14-7.88), ≥35 years of age(aO R 3.04), non-Han ethnicity(aO R 1.67), and farming as an occupation(aO R 1.59). For patients with TB/HIV co-infection, miliary TB was the strongest risk factor for death(aO R 5.48). A low CD4 count(≤ 200 cells/μL)(aO R 3.27) at the time of TB treatment initiation and a lack of antiretroviral therapy(ART) administration(aO R 3.78) were also correlated with an increased risk of death. Conclusion Infection with HIV was independently associated with increased mortality during TB treatment. Offering HIV testing at the time of diagnosis with TB, early TB diagnosis among HIV/acquired immunodeficiency syndrome patients, and the timely provision of ART were identified as the key approaches that could reduce the number of HIV-associated TB deaths.LAI Yu Ji LIU Er Yong WANG Li Ming Jamie P MORANO WANG Ning Kaveh KHOSHNOOD ZHOU Lin CHENG Shi Ming 2015Biomedical and Environmental Sciences2015,28,6:4

14Dissociation behavior of “dry water” C_3H_8 hydrate below ice point:Effect of phase state of unreacted residual water on a mechanism of gas hydrates dissociation显示文摘The results on a dissociation behavior of propane hydrates prepared from 'dry water' and contained unreacted residual water in the form of ice inclusions or supercooled liquid water(water solution of gas) were presented for temperatures below 273 K.The temperature ramping or pressure release method was used for the dissociation of propane hydrate samples.It was found that the mechanism of gas hydrate dissociation at temperatures below 273 K depended on the phase state of unreacted water in the hydrate sample.Gas hydrates dissociated into ice and gas if the ice inclusions were in the hydrate sample.The samples of propane hydrates with inclusions of unreacted supercooled water only(without ice inclusions) dissociated into supercooled water and gas below the pressure of the supercooled water-hydrate-gas metastable equilibrium.Andrey O Drachuk Vladimir P Melnikov Nadezhda S Molokitina Anatoliy N Nesterov Lev S Podenko Aleksey M Reshetnikov Andrey Yu Manakov 2015Journal of Energy Chemistry2015,24,3:2

17Structure and property of metal melt Ⅲ—Relationship between kinematic viscosity and size of atomic clusters显示文摘The method of crucible rotating oscillation damping was employed to measure the kinematic viscosity of aluminum melt,and the curve of viscosity v versus temperature T from 935 to 1383 K was obtained.Besides,based on the calculation model of the evolution behavior of atomic clusters in liquid structure,the curve of atomic clusters size d versus temperature was obtained,and the calculated results are in good agreement with the experimental values.By analyzing experimental data,it was found that both the viscosity and the size of atomic clusters of aluminum melt are monodrome functions of temperature,and the relation between v(T) and d(T) is a linear function,i.e.,v = v 0 + K·d(T).This relation indirectly verifies the calculation model of the structural information of metal melt,which is of great significance for studying the relation between melt microstructure and macro-physical properties.POPEL P S KONSTANTINOVA N Yu 2010Science China(Physics,Mechanics & Astronomy)2010,53,11:2

19Fluorescence and SEM correlative microscopy for nanomanipulation of subcellular structures显示文摘Nanomanipulation under scanning electron microscopy(SEM)enables direct interactions of a tool with a sample.We recently developed a nanomanipulation technique for the extraction and identification of DNA contained within sub-nuclear locations of a single cell nucleus.In nanomanipulation of sub-cellular structures,a key step is to identify targets of interest through correlating fluorescence and SEM images.The DNA extraction task must be conducted with low accelerating voltages resulting in low imaging resolutions.This is imposed by the necessity of preserving the biochemical integrity of the sample.Such poor imaging conditions make the identification of nanometer-sized fiducial marks difficult.This paper presents an affine scale-invariant feature transform(ASIFT)based method for correlating SEM images and fluorescence microscopy images.The performance of the image correlation approach under different noise levels and imaging magnifications was quantitatively evaluated.The optimal mean absolute error(MAE)of correlation results is 68634 nm under standard conditions.Compared with manual correlation by skilled operators,the automated correlation approach demonstrates a speed that is higher by an order of magnitude.With the SEM-fluorescence image correlation approach,targeted DNA was successfully extracted via nanomanipulation under SEM conditions.Zheng Gong Brandon K Chen Jun Liu Chao Zhou Dave Anchel Xiao Li Ji Ge David P Bazett-Jones Yu Sun 2014Light(Science & Applications)2014,3,1:2
