| 1 | Diagnostic accuracy of endoscopic ultrasound in pancreatic neuroendocrine tumors: A systematic review and meta analysis显示文摘AIM: To detect pancreatic neuroendocrine tumors (PNETs) has been varied. This study is undertaken to evaluate the accuracy of endoscopic ultrasound (EUS) in detecting PNETs.METHODS: Only EUS studies confirmed by surgery or appropriate follow-up were selected. Articles were searched in Medline, Ovid journals, Medline nonindexed citations, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews. Pooling was conducted by both fixed and random effects model). RESULTS: Initial search identified 2610 reference articles, of these 140 relevant articles were selected and reviewed. Data was extracted from 13 studies (n = 456) which met the inclusion criteria. Pooled sensitivity of EUS in detecting a PNETs was 87.2% (95%CI: 82.2-91.2). EUS had a pooled specificity of 98.0% (95%CI: 94.3-99.6). The positive likelihood ratio of EUS was 11.1 (95%CI: 5.34-22.8) and negative likelihood ratio was 0.17 (95%CI: 0.13-0.24). The diagnostic odds ratio, the odds of having anatomic PNETs in positive as compared to negative EUS studies was 94.7 (95%CI: 37.9-236.1). Begg-Mazumdar bias indicator for publication bias gave a Kendall's tau value of 0.31 (P = 0.16), indication no publication bias. The P for χ2 heterogeneity for all the pooled accuracy estimates was > 0.10. CONCLUSION: EUS has excellent sensitivity and specificity to detect PNETs. EUS should be strongly considered for evaluation of PNETs. | Srinivas R Puli Nikhil Kalva Matthew L Bechtold Smitha R Pamulaparthy Micheal D Cashman Norman C Estes Richard H Pearl Fritz-Henry Volmar Sonu Dillon Michael F Shekleton David Forcione | 2013 | World Journal of Gastroenterology2013,19,23: | 14 |
| 2 | Immunogenetic factors driving formation of ultralong VH CDR3 in Bos taurus antibodies显示文摘The antibody repertoire of Bos taurus is characterized by a subset of variable heavy(VH)chain regions with ultralong third complementarity determining regions(CDR3)which,compared to other species,can provide a potent response to challenging antigens like HIV env.These unusual CDR3 can range to over seventy highly diverse amino acids in length and form uniqueβ-ribbon‘stalk’and disulfide bonded‘knob’structures,far from the typical antigen binding site.The genetic components and processes for forming these unusual cattle antibody VH CDR3 are not well understood.Here we analyze sequences of Bos taurus antibody VH domains and find that the subset with ultralong CDR3 exclusively uses a single variable gene,IGHV1-7(VHBUL)rearranged to the longest diversity gene,IGHD8-2.An eight nucleotide duplication at the 3′end of IGHV1-7 encodes a longer V-region producing an extended Fβ-strand that contributes to the stalk in a rearranged CDR3.A low amino acid variability was observed in CDR1 and CDR2,suggesting that antigen binding for this subset most likely only depends on the CDR3.Importantly a novel,potentially AID mediated,deletional diversification mechanism of the B.taurus VH ultralong CDR3 knob was discovered,in which interior codons of the IGHD8-2 region are removed while maintaining integral structural components of the knob and descending strand of the stalk in place.These deletions serve to further diversify cysteine positions,and thus disulfide bonded loops.Hence,both germline and somatic genetic factors and processes appear to be involved in diversification of this structurally unusual cattle VH ultralong CDR3 repertoire. | Thaddeus C Deiss Melissa Vadnais Feng Wang Patricia L Chen Ali Torkamani Waithaka Mwangi Marie-Paule Lefranc Michael F Criscitiello Vaughn V Smider | 2019 | Cellular & Molecular Immunology2019,16,1: | 4 |
| 3 | p53-mediated transcriptional regulation and activation of the actin cytoskeleton regulatory RhoC to LIMK2 signaling pathway promotes cell survival显示文摘响应 DNA 损坏的房间命运的中央仲裁人是 p53,它调整涉及房间周期拘捕,幸存和 apoptosis 的基因的表示。尽管 DNA 损坏开始的许多回答被描绘了,肌动朊细胞骨架管理者的角色大部分是未知的。我们现在显示出那 RhoC 和秘鲁利玛机场之代号 kinase (LIMK2 ) 2 是 genotoxic 代理人导致的直接 p53 目标基因。尽管 RhoC 和 LIMK2 在肌动朊细胞骨架规定有生长得很好的角色,我们的结果显示 LIMK2 的激活也有支持幸存的功能追随者 DNA 损坏。由调停 siRNA 的击倒或选择的药理学封锁的 LIMK 抑制敏化房间到无线电 -- 或化疗,以便当与 LIMK 抑制结合了时,当单身地管理了时,是尚不致命的治疗导致了房间死亡。我们的调查结果建议把 LIMK 禁止者与 genotoxic 治疗相结合能比单个代理人的管理更有效,并且加亮在肌动朊细胞骨架管理者和 DNA 之间的一个新奇连接导致损坏的房间幸存机制。 | Daniel R Croft Diane Crighton Michael S Samuel Filipe C Lourenco June Munro Jenifer Wood Karim Bensaad Karen H Vousden Owen J Sansom Kevin M Ryan Michael F Olson | 2011 | Cell Research2011,21,4: | 3 |

| 5 | Reduced striatal volumes in Parkinson’s disease:a magnetic resonance imaging study显示文摘Background:The presence and extent of structural changes in the brain as a consequence of Parkinson’s disease(PD)is still poorly understood.Methods:High-resolution 3-tesla T1-weighted structural magnetic resonance images in sixty-five PD and 27 age-matched healthy control participants were examined.Putamen,caudate,and intracranial volumes were manually traced in the axial plane of 3D reconstructed images.Striatal nuclei volumes were normalized to intracranial volume for statistical comparison.Disease status was assessed using the Unified Parkinson’s Disease Rating Scale and Hoehn and Yahr scale.Cognitive status was assessed using global status tests and detailed neuropsychological testing.Results:Both caudate and putamen volumes were smaller in PD brains compared to controls after adjusting for age and gender.Caudate volumes were reduced by 11%(p=0.001)and putamen volumes by 8.1%(p=0.025).PD striatal volumes were not found to be significantly correlated with cognitive or motor decline.Conclusion:Small,but significant reductions in the volume of both the caudate and putamen occur in PD brains.These reductions are independent of the effects of age and gender,however the relation of these reductions to the functional loss of dopamine,which is characteristic of PD,remains unclear. | Toni L Pitcher Tracy R Melzer Michael R MacAskill Charlotte F Graham Leslie Livingston Ross J Keenan Richard Watts John C Dalrymple-Alford Tim J Anderson | 2012 | Translational Neurodegeneration2012,1,1: | 2 |
