| 1 | The Ozone Component of Global Change:Potential Effects on Agricultural and Horticultural Plant Yield,Product Quality and Interactions with Invasive Species显示文摘The productivity,product quality and competitive ability of important agricultural and horticultural plants in many regions of the world may be adversely affected by current and anticipated concentrations of ground-level ozone(O3).Exposure to elevated O3 typically results in suppressed photosynthesis,accelerated senescence,decreased growth and lower yields.Various approaches used to evaluate O3 effects generally concur that current yield losses range from 5% to 15% among sensitive plants.There is,how-ever,considerable genetic variability in plant responses to O3.To illustrate this,we show that ambient O3 concentrations in the eastern United States cause substantially different levels of damage to otherwise similar snap bean cultivars.Largely undesirable effects of O3 can also occur in seed and fruit chemistry as well as in forage nutritive value,with consequences for animal production.Ozone may alter herbicide efficacy and foster estab-lishment of some invasive species.We conclude that current and projected levels of O3 in many regions worldwide are toxic to sensitive plants of agricultural and horticultural significance.Plant breeding that incorporates O3 sensitivity into selection strategies will be increasingly necessary to achieve sustainable production with changing atmospheric composition,while reductions in O3 precursor emissions will likely benefit world food pro-duction and reduce atmospheric concentrations of an important greenhouse gas. | Fitzgerald Booker Russell Muntifering Margaret McGrath Kent Burkey Dennis Decoteau Edwin Fiscus William Manning Sagar Krupa Arthur Chappelka David Grantz | 2009 | Journal of Integrative Plant Biology2009，51，4： | 18 |
| 2 | 我对贾樟柯电影的一些看法显示文摘贾樟柯生于1970年,山西汾阳人,1997年毕业于北京电影学院文学系电影理论专业。他是中国新生代电影导演群体的中坚,“故乡三部曲”之《小武》《站台》和《任逍遥》成为新生代电影的重要代表。同时他身体力行,参与并引导了中国新兴的青年DV电影创作活动。从某种意义上说,关注“贾樟柯现象”其实就是对中国新生代电影研究关键词的一种梳理,如边缘化、平民视角、现实主义、都市化、新DV运动和美学转型等等。本期的四篇论文中,美国明尼苏达大学JasonMcGrath教授的论文《我对贾樟柯电影的一些看法》从比较电影研究的视角,强调贾樟柯早期影片创作在新纪实运动的影响下逐渐显露出独特的现实主义风格,这种“如其所是”的现实影像不同于政治现实主义和第五代的寓言式电影,从而表现出国际艺术片普遍具有的世界性美学特征。林少雄教授《贾樟柯影像的文化意蕴》从身份认同观念、视像书写意识、时间感悟体验与空间建构意识等方面,探讨中国新生代导演全新的“影像本体”美学的建构过程。刘志荣博士《漫谈贾樟柯的“故乡三部曲”》从切实的感性实感出发,指出贾樟柯电影是从日常生活中升腾起来的“无邪”之诗,这源于导演本人对于生活世界保持的开放态度以及对文化之根的溯求。王卓慈副教授《修复失忆的影像表达》 | Jason McGrath 聂伟 | 2005 | 杭州师范学院学报(社会科学版)2005，27，2： | 11 |
| 3 | Freezing osteoblast cells attached to hydroxyapatite discs and glass coverslips: Mechanisms of damage显示文摘Damage mechanisms for osteoblast cells (OBs) attached to hydroxyapatite (HA) discs and glass coverslips were comprehensively investigated. Cell-cell, cell-matrix interaction altered the cryobiological properties of cells. Attached cells were sub- ject to more severe mechanical damage than isolated cells because attached cells had larger contacting area with ice and the three dimensional movements of iso- lated cells made them more flexible than attached cells that could only deform in one dimension. Results showed that the viability of attached OB cells decreased significantly compared with the viability of isolated OB cells under the same cryo- preservation procedure. Extracellular ice, differential thermal contraction, and mechanical stresses were the major damaging factors for OB cells attached to HA discs and glass coverslips. | McGRATH John | 2007 | Science China(Technological Sciences)2007，50，2： | 9 |

| 5 | 脉压对颈动脉壁重构的影响——探讨Laplace定律对大血管重构的作用显示文摘目的:血管壁的增厚和功能指数正越来越多的被用作评价心血管疾病的重要指标。然而大血管的结构、功能、压力的相互关系在活体上还没有很好的确定。我们研究组对一组正常和高血压病人进行了大血管的结构-功能-压力的相互关系的交叉研究。方法:307例正常和高血压的人群被选择到此研究,其中男110例,女197例。年龄49~75岁。颈动脉内膜和中层厚度(Intima-media wall thickness,IMT)和内腔直径(Lumen diameter,LD)用Diasonic(DRF400)高分辨率超声来确定。血管壁环状压(Circumferential stress,Cs)是依据LAPLACE定律(δ=P×r/h)计算。其中压力(Pressure,P)用平均压和脉压两种方法计算。此动脉的结构和功能指数用年龄、身高和心率来校正。颈动脉压用无创压力感受器测定。结果:共有70例高血压(BP>140/90)患者。用年龄、身高和心率校正后的内中膜厚度和内腔直径在高血压组显著增加。而且IMT随着脉压的增大而增大(r=0.39,P<0.001)。内腔半径与内中膜厚度比值(R/IMT,R=LD/2)和环状压在高血压组明显增加。但是不管高血压或正常人群的R/IMT比值与脉压呈负相关关系(r=0.38,P<0.001),而与平均压无关。结论:在高血压状态下颈动脉壁重构是服从LAPLACE定律的,但颈动脉壁重构不足以抵销高血压状态下的血管壁环状压的增加。 | 梁雨露 Cameron J McGrath BP | 2002 | 中国医药导刊2002，4，1： | 4 |
| 6 | Gastric endoscopic submucosal dissection as a treatment for early neoplasia and for accurate staging of early cancers in a United Kingdom Caucasian population显示文摘AIM To investigate the efficacy of endoscopic submucosal dissection(ESD) at diagnosing and treating superficial neoplastic lesions of the stomach in a United Kingdom Caucasian population.METHODS Data of patients treated with or considered for ESD at a tertiary referral center in the United Kingdom were retrieved for a period of 2 years(May 2015 to June 2017) from the electronic patient records of the hospital. Only Caucasian patients were included. Primary outcomes were curative resection(CR) and were defined as ESD resections with clear horizontal and vertical margin and an absence of lympho-vascular invasion, poor differentiation and submucosal involvement on histological evaluation of the resected specimen. Secondary end-points were reversal of dysplasia at 12 mo endoscopic follow-up and/or at the latest follow up. Change in histological diagnosis pre and post ESD was also analysed.RESULTS Twenty-four patients were initially identified with intention to treat. 19 patients were eligible after mapping gastroscopy and ESD was attempted on a total of 25 ESD lesions, 4 of which failed and had to be aborted mid-procedure. Out of 21 ESD performed, en-bloc resection was achieved in 71.4% of cases. Resection was considered complete on endoscopy in 90.5% of cases compared to only 38.1% on histology. A total of 6 resections were considered curative(28%), 5 noncurative(24%) and 10 indefinite for CR or non-CR(24%). ESD changed the histological diagnosis in 66.6% of cases post ESD. Endoscopic follow-up in the 'indefinite' group and CR group showed that 50% and 80% of patients were clear of dysplasia at the latest follow-up respectively; 2 cases of recurrence were observed in the 'indefinite'group. Survival rate for the entire cohort was 91.7%.CONCLUSION This study provides early evidence for the efficacy of ESD as a therapeutic and diagnostic intervention in Caucasian populations and supports its application in the United Kingdom. | Aisha Sooltangos Matthew Davenport Stephen McGrath Jonathan Vickers Siba Senapati Kurshid Akhtar Regi George Yeng Ang | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，12： | 3 |
| 7 | Mutations in EZH2 are associated with poor prognosis for patients with myeloid neoplasms显示文摘EZH2 is a component of the polycomb repressive complex 2(PRC2),which is a highly conserved histone methyltransferase that methylates lysine 27 of histone 3.EZH2 mutations are associated with oncogenesis and progression of cancers.However,the relationship between the clinical outcome of patients with myeloid malignancies and EZH2 mutations is controversial.Therefore,we performed a meta-analysis of 8 studies(n Z 2243 patients)that evaluates the correlation between EZH2 mutations and overall survival(OS)in patients with myeloid neoplasms.EZH2 mutations were associated with significantly worse OS(hazard ratio[HR]Z 2.37,95%confidential interval(CI),1.48e3.79).In a word,EZH2 mutations indicate a poor prognosis for patients with myeloid neoplasms. | Qi Zhang Qi Han Jie Zi Jinlong Ma Huihui Song Yulu Tian Mary McGrath Chunhua Song Zheng Ge | 2019 | Genes & Diseases2019，6，3： | 3 |
| 8 | High level HIV-1 DNA concentrations in brain tissues differentiate patients with post-HAART AIDS dementia complex or cardiovascular disease from those with AIDS显示文摘Highly active antiretroviral treatment(HAART) has had a significant impact on survival of individuals with acquired immunodeficiency syndrome(AIDS);however,with the longer life-span of patients with AIDS,there is increasing prevalence of AIDS dementia complex(ADC) and other non-AIDS-defining illness,and cardiovascular diseases(CVD) are also common.The influence of these varied disease processes on HIV-1 DNA concentration in brain tissues has not been thoroughly assessed in the post-HAART era.The purpose of the current study is to clarify the impacts of ADC and other complications of HIV disease on the viral load in the brains in AIDS patients with post-HARRT.We examined autopsy specimens from the brains of thirteen patients who died from complications of AIDS with quantitative polymerase chain reaction(QPCR).All but one patient had received HAART prior to death since 1995.Two patients died with severe CVD,multiple cerebrovascular atherosclerosis(CVA) throughout the brain and five patients died with ADC.Six patients had no ADC/CVA.A QPCR was used to measure the presence of HIV-1 DNA in six brain tissues(meninges,frontal grey matter,frontal white matter,temporal subcortex,cerebellum and basal ganglia).In the post-HARRT era,for non-ADC/CVA patients,HIV-1 DNA concentration in brain tissues was statistically higher than that in patients with ADC.In a new finding,two patients who suffered from severe CVD,especially CVA,also had high concentrations of HIV-1 in brain compartments not showing ADC related changes.To our knowledge,this is the first report of a relationship between the CVA and HIV-1 viral burden in brain.The current observations suggest that HAART-resistant HIV reservoirs may survive within ADC lesions of the brain as well as the macrophage rich atherosclerosis,which needs to be confirmed by more AIDS cases with CVA. | GALLIGAN Derek C.
