1Analysis of the phosphatidylinosit ol 3'-kinase signaling pathway in glioblastoma patients in vivo显示文摘Deregulated signaling through the p hosphatidylinositol 3-kinase(PI3K)pathway is common in many types of can cer,including glioblastoma.Dissecting the molecular events associated with activation of this pathway in glioblastoma p atients in vivo presents an important challenge that has implic ations for the development and clini cal testing of PI3K pathway inhibito rs.Using an immunohistochemical analysis appl ied to a tissue microarray,we performed hierarchical clustering and mul tidimensional scaling,as well as univariate and multivariate analyses,to dissect the PI3K pathway in v ivo.We demonstrate that loss of the t umor suppressor protein PTEN,which antagonizes PI3K pathwa y activation,is highly correlated w ith activation of the main PI3K effec tor Akt in vivo.We also show that Akt activation is signific antly correlated with phosphorylation of mammalian target of rapamycin(mTOR),the family of forkhead transcription factors(FOXO1,FOXO3a,and FOXO4),and S6,which are thought to promote its effects.Expression of the mutan t epidermal growth factor receptor vIII is also tightly correlated with phosphorylation of these effectors,d emonstrating an additional route to PI3K pathway activation in glioblastomas in vivo.These results provide the first dissection of the PI3K path way in glioblastoma in vivo and suggest an approach to stratifying patients for targeted kinase inhi bitorChoe G Horvath S Cloughesy TF Crosby K Seligson D Palotie A Inge L Smith BL Sawyers CL Mischel PS 2003癌症2003,22,7:41
2健康领域的文化能力显示文摘1背景 尽管人类对其他社会的兴趣纵贯历史的各个阶段,但是检验不同文化概念对人类健康实践的影响从20世纪才开始,当时是伴随着长期的人类学田野调查产生的,这些田野调查揭露了不同文化之间相关卫生实践的多样性、复杂性和连续性。Napier A D Ancarno C Butler B Calabrese j Chater A Chatterjee H Guesnet F Home R Jacyna S Jadhav S Macdonald A Neuendorf U Parkhurst A Reynolds R Scambler G Shamdasani S Smith S Z Stougaard-Nielsen J Thomson L Tyler N Volkmann A M Walker T Watson J Williams AC Willott C Wilson J Woolf K 2016中国卫生政策研究2016,9,2:5

4Global Wheat Head Detection 2021:An Improved Dataset for Benchmarking Wheat Head Detection Methods显示文摘The Global Wheat Head Detection(GWHD)dataset was created in 2020 and has assembled 193,634 labelled wheat heads from 4700 RGB images acquired from various acquisition platforms and 7 countries/institutions.With an associated competition hosted in Kaggle,GWHD_2020 has successfully attracted attention from both the computer vision and agricultural science communities.From this first experience,a few avenues for improvements have been identified regarding data size,head diversity,and label reliability.To address these issues,the 2020 dataset has been reexamined,relabeled,and complemented by adding 1722 images from 5 additional countries,allowing for 81,553 additional wheat heads.We now release in 2021 a new version of the Global Wheat Head Detection dataset,which is bigger,more diverse,and less noisy than the GWHD_2020 version.Etienne David Mario Serouart Daniel Smith Simon Madec Kaaviya Velumani Shouyang Liu Xu Wang Francisco Pinto Shahameh Shafiee Izzat SATahir Hisashi Tsujimoto Shuhei Nasuda Bangyou Zheng Norbert Kirchgessner Helge Aasen Andreas Hund Pouria Sadhegi-Tehran Koichi Nagasawa Goro Ishikawa Sébastien Dandrifosse Alexis Carlier Benjamin Dumont Benoit Mercatoris Byron Evers Ken Kuroki Haozhou Wang Masanori Ishii Minhajul ABadhon Curtis Pozniak David Shaner LeBauer Morten Lillemo Jesse Poland Scott Chapman Benoit de Solan Frédéric Baret Ian Stavness Wei Guo 2021Plant Phenomics2021,3,1:2

7文化、不平等性与卫生服务提供显示文摘1动态不平等性对基层医疗卫生人力的影响 政治、社会、文化、专业群体皆建立在一致且常规的人类行为之上。当遭受巨大变革和内外压力时,这些群体会变得十分脆弱。尤其在动荡时期,这些群体往往更关注社会和文化的差异性,而非二者的一致性。尽管社会中的个体思维和行为会呈现较大的差异,但对健康的感知具有统一性,并在更广范围人群内尤为突出,这主要归因于文化价值观的作用。广义的文化心态会随着时间和地理位置的不同而不同,就像健康的社会决定因素也会因文化类型的不同而产生差异。Napier A D Ancarno C Butler B Calabrese J Chater A Chatterjee H Guesnet F Horne R Jacyna S Jadhav S Macdonald A Neuendorf U Parkhurst A Reynolds R Scambler G Shamdasani S Smith S Z Stougaard-Nielsen J Thomson L Tyler N Volkmann A M Walker T Watson J Williams A C Willott C Wilson J Woolf K 2016中国卫生政策研究2016,9,3:2

9西双版纳傣族及上海汉族群体HLA-DR2相关的DR/DQ单倍型分析显示文摘对44名西双版纳傣族和9名上海地区汉族DK2阳性个体进行了与其相关的DR/DQ单倍型组合的分析。傣族群体中DRBI-DR2亚型分布以*1602与*1502为最常见,其等位基因频率分别为43.6%与,40.0%和汉族群体中以*1501为主明显不同。傣族群体中共检出10种与DR2相关联的DR/DQ单倍型;最常见的是DRB1*1602、DRB5*0101、DQA1*0102、DQB1*0502(34.5%)与汉族及其他群体明显不同,本研究表明傣族不仅具有高频率的DR2,而且与DR2相关联的DRB1、DRB5、DQA1、DQB1单倍型组合有其独特性。范丽安 杨珏琴 姚芳娟 董建中 许玲娣 陈仁彪 M Sirkong R Vongrathna P Longta S Lekmak D Chandanayingyong A Smith J Hansen 1995中华医学遗传学杂志1995,12,3:2
