求高人解答:fluctuate的用法!

用fluctuate between and。不过这不是主要问题……你的句子显得比较累赘,而且语序不太对。下面这样写能好一点:The electricity consumption fluctuates between 30000 and 50000 units in winter and between 13000 and 20000 units in summer.看起来“and”有点多,不过你坚持用fluctuate between and的话就只好这样了,不会引起歧义。像季节这样的限定一般跟在后面,跟汉语习惯不同。另外respectively是用在所有对应的列举都完了的最后,不会像你这样夹在句子中间或者列举的中间。

ROC曲线——相关文献实例、原理和绘制方法

数据分析最让人着迷的一种用途是可以基于现有数据创建能够区分不同类型情景的机器学习预测模型。通过定义明确的模型,可以确定能够预测结果的最重要影响因素,为战略假设开发有价值的洞察力,甚至可以通过友好的用户界面将模型的逻辑实现到软件应用程序中。 首先,我们需要评估构建好的预测模型是否具有良好准确的预测能力!比如,如果我们的电子邮件程序的垃圾邮件分类器只能检测到50%的不需要的电子邮件或请求,我们都会非常愤怒。本文将讨论如何使用经典工具来评估预测模型:接收器操作特性(ROC)曲线。 本文主要分为三个部分整理ROC曲线相关内容,可根据自己的需要进行挑选: 1、使用ROC曲线分析的相关文献实例 2、ROC曲线的原理和历史 3、如何绘制ROC曲线 从一篇SCI出发: Improvement of Insulin Sensitivity after Lean Donor Feces in Metabolic Syndrome Is Driven by Baseline Intestinal Microbiota Composition 这是阿姆斯特丹大学学术医学中心在2017年发表在cell子刊上的文献,其中一个highlight提到:Response to lean donor FMT is driven by baseline fecal microbiota composition,使用了ROC曲线来评估预测模型的好坏。 为了比较异体FMT中菌群与效果之间的关系,首先按照FMT前后Rd值的变化将患者分为responders组和non-responders组,并比较了两组的菌群差异,从菌群多样性变化来看,基于Shannon指数发现,两组的多样性均没有发生显著改变,然而,两组基线时的菌群多样性却又显著差异(图5A),具体表现为non-responders的基线菌群多样性显著高于responders。随后,作者使用了弹性网络算法elastic net algorithm ( Zou and Hastie, 2005 )区分responders和non-responders,为了避免过度拟合,在数据的训练分区(80%)上使用了十折交叉验证,剩下的20%样品用作测试数据集。要选择的参数是 L1,L2范数和正则化阈值之间的比率。稳定性选择采用80% 的随机二次抽样方法进行,共100次。在稳定性选择过程中,计算所有权重系数为非零的特征。这些计数被归一化并转换为稳定系数,对于总是被选择的特征值在1.0之间,对于从未被选择的特征值在0.0之间。通过随机试验评价弹性网络算法所得结果的统计有效性。按照程序将结果变量(例如,同种异体相对于自体或应答者相对于无应答者)随机重组,同时保留相应的微生物谱。重复100次,每次计算受试者-工作特征-曲线下面积(ROC AUC)评分。用于二进制分类任务的性能度量是 ROC AUC。ROC 可以理解为一个正确分类同种异体受试者与自体受试者或有效者与无效者的概率图。数据集中的交叉验证是通过随机隐藏模型中20% 的受试者并评估该组的预测质量来完成的。ROC AUC 评分用0.5 AUC 来衡量分类模型的预测准确性,对应于一个随机结果。定义了一个临界值0.05,并将原始数据集的真实 AUC 与此值进行了比较。 作者通过ROC曲线评估了基线菌群组成预测6周代谢反应的模型,显示AUC=0.88,模型良好。 从这篇文献了解到ROC曲线可用于评估某个寻找biomarkers的预测模型的好坏。再从一篇SCI了解: Alterations in the gut microbiome and metabolism with coronary artery disease severity 这是一篇本课题组与北京协和医学院合作在2019年发表的文章,关注了不同冠状动脉疾病Coronary artery disease (CAD)类型患者的肠道菌群区分差异。其中,作者通过ROC曲线评估了区分不同CAD亚型(稳定型冠状动脉疾病(SCAD) ,不稳定型心绞痛(UA)和心肌梗死(MI))的特征共变化菌群和代谢物随机森林模型,得到比较良好的预测结果。 Subgroup identification and prediction based on CAGs and CAD-associated metabotypes 为了确定肠道菌群中的 CAGs 和代谢产物模块是否可以作为鉴别冠心病不同阶段与正常冠状动脉的生物标志物,根据24个 CAGs 和72个血清代谢类型构建了随机森林模型对冠心病不同阶段进行分类,并利用 ROC曲线(ROC)曲线对分类进行了检验(详情见“材料和方法”一节)。总共构建了5个预测模型(Control vs. CAD, Control vs. SCAD, SCAD vs. UA, SCAD vs. ACS和UA vs. MI)。 随后,作者再通过招募新队列使用该模型进行分类预测,进一步论证该疾病亚型识别模型的潜在分类能力。 小结:从这两篇文献来看,作者均通过某个分类法机器学习预测模型寻找biomarkers,然后使用ROC曲线对模型进行评估。因此,我们可以初步得知,ROC曲线是用于检验构建的预测模型好坏的一种衡量方法。那么除了这种用途,ROC曲线还能做什么呢? 为了进一步了解并应用ROC曲线,我们需要首先了解ROC曲线的原理和过往↓ 关于ROC曲线相关介绍的文章非常多,这里我摘抄出个人认为比较详细,可用性强的文章,加以理解。 一、评估预测模型的方法 首先,我们应该了解到预测模型的类型可以分为回归模型和分类模型(分类模型又有两类算法:分类输出型和概率输出型,这里就不一一赘述),而不同模型的评估度量也是不同的, 如何评估模型好坏 , 机器学习(二十四)——常见模型评估方法 , 分类模型的评估方法简介 首先需要了解自己构建的预测模型类型来决定评估方法,并不局限于使用ROC曲线进行评估。 ROC曲线原理: 关于ROC曲线的概念和意义可参考: ROC曲线的概念和意义 英文比较好的话也可以看看这篇: ROC curves – what are they and how are they used? 为了更直观的理解ROC,也可以看看这个视频: ROC and AUC, Clearly Explained! 受试者工作特征曲线(receiver operator characteristic curve, ROC曲线),最初用于评价雷达性能,又称为接收者操作特性曲线。ROC曲线其实就是从混淆矩阵衍生出来的图形,以真阳性率(灵敏度,Sensitivity)为纵坐标,假阳性率(1-特异度,1-Specificity)为横坐标绘制的曲线。 其自变量(检验项目)一般为连续性变量(如蛋白质因子、菌株、代谢物等的检测丰度或含量),因变量(金标准,如某疾病亚型分类、治疗响应和无响应、患病和未患病)一般为二分类变量。 ROC曲线图形:随着阈值的减小,更多的值归于正类,敏感度和1-特异度也相应增加,所以ROC曲线呈递增趋势。那条45度对角线是一条参照线,也就是说ROC曲线要与这条曲线比较。简单的说,如果我们不用模型,直接随机把客户分类,我们得到的曲线就是那条参照线,然而我们使用了模型进行预测,就应该比随机的要好,所以ROC曲线要尽量远离参照线,越远,我们的模型预测效果越好。 ROC曲线就是用来判断诊断的正确性,最理想的就是曲线下的面积为1,比较理想的状态就是曲线下的面积在0.8-0.9之间,0.5的话对实验结果没有什么影响。 提到ROC曲线,就离不开AUC(ROC曲线下面积),其判定方法为AUC应该大于0.5。ROC曲线是根据与对角线进行比较来判断模型的好坏,但这只是一种直觉上的定性分析,如果我们需要精确一些,就要用到AUC,也就是ROC曲线下面积(AUC)。 从AUC判断分类器(预测模型)优劣的标准: AUC = 1,是完美分类器,采用这个预测模型时,存在至少一个阈值能得出完美预测。绝大多数预测的场合,不存在完美分类器。 0.5 < AUC < 1,优于随机猜测。这个分类器(模型)妥善设定阈值的话,能有预测价值。 AUC = 0.5,跟随机猜测一样(例:丢铜板),模型没有预测价值。 AUC < 0.5,比随机猜测还差;但只要总是反预测而行,就优于随机猜测。 看上图,参考线的面积是0.5,ROC曲线与它偏离越大,ROC曲线就越往左上方靠拢,它下面的面积(AUC)也就越大,这里面积是0.869。我们可以根据AUC的值与0.5相比,来评估一个分类模型的预测效果。 二、ROC曲线的历史和关键值 这里推荐阅读这篇: 机器学习基础(1)- ROC曲线理解 。这里从最初雷达兵使用ROC曲线评估的故事说起,言简意赅。 ROC曲线最初的研究是为了确定美国雷达“接收机操作员”是如何漏掉日本飞机的。在模型预测判断中,会出现真阳、假阳、真阴和假阴的三种情况,而不同雷达兵都可能有自己的一套评判标准,对每个接收的信号是大鸟还是轰炸机,每个雷达兵会给出自己的判断结果,这样每个雷达兵就都能计算出一个ROC曲线上的关键点(一组FPR,TPR值),把大家的点连起来,也就是最早的ROC曲线了。 ROC曲线需要了解几个关键值: 敏感性: 正确识别真阳性的比例。在这种情况下,健康患者的比例由诊断工具正确识别。这有时被称为“召回”。 SN =真阳性/(真阳性+假阴性) 逆(1灵敏度)=  假负率 。未被该工具检测到的健康患者被错误地识别为患有CAD。假阴性也称为II型错误。 特异性: 正确识别真阴性的比例。在这种情况下,通过诊断工具正确识别CAD患者的比例。 SP =真阴性/(真阴性+误报) 逆(1-特异性)=  假阳性率 。CAD患者被错误地识别为无CAD。误报也称为I型错误。 积极预测价值: 该工具报告的阳性比例,实际上是积极的。对于诊断工具报告缺乏CAD的患者组,PPV是实际上没有患病的患者的比例。这有时被称为“精确度”。 PPV =真阳性/(真阳性+误报) 负面预测值: 该工具报告的负面影响的比例,实际上是负面的。对于诊断工具报告存在CAD的患者组,NPV是实际上没有CAD的患者的比例。 NPV =真阴性/(真阴性+假阴性) 这里可以借助混淆矩阵加以理解: TP(True Positive): 真实为0,预测也为0 FN(False Negative): 真实为0,预测为1 FP(False Positive): 真实为1,预测为0 TN(True Negative): 真实为0,预测也为0 三、ROC曲线的主要作用 1、ROC曲线能很容易地查出任意界限值时的对疾病的识别能力。 2、选择最佳的诊断界限值。 3、两种或两种以上不同诊断试验对疾病识别能力的比较。在对同一种疾病的两种或两种以上诊断方法进行比较时,可将各试验的ROC曲线绘制到同一坐标中,以直观地鉴别优劣,靠近左上角的ROC曲线所代表的受试者工作最准确。亦可通过分别计算各个试验的ROC曲线下的面积(AUC)进行比较,哪一种试验的AUC最大,则哪一种试验的诊断价值最佳。 四、交叉验证和过拟合问题 参考: 你真的了解交叉验证和过拟合吗? 机器学习】Cross-Validation(交叉验证)详解 10折交叉验证(10-fold Cross Validation)与留一法(Leave-One-Out)、分层采样(Stratification) 意识到过拟合好像也是个棘手的问题,所以在这里补充一下: 简单来讲,当 train set 误差较小,而 test set 误差较大时,我们即可认为模型过拟合。这句话表达的另一层意思是,模型评估指标的方差(variance)较大,即可认为模型过拟合。另外,无论监督学习还是非监督学习,均存在过拟合的问题。 有一个比喻还不错,这里也摘抄下来: 语文老师 让同学A 解释一个句子:  ‘某鲁迅先生的文章~~~~~~~~" 欠拟合:    差生: 这是个什么鬼东西,比例哔哩哔哩~~~~ 过拟合:    语文老师的解释: ‘表面上看是~~~,但其实~~~~,本质上~~~~~~,反映了~~~~心情,烘托了~~~气氛~~~" 正常:        当时鲁迅先生觉得天色晚了,该休息了。 那么,如何才能够在一定程度上避免过拟合呢?这就引出了交叉验证: 最简单的判断模型是否过拟合的方法,就是通过training accuracy 和 test accuracy 数值大小,直观的判断模型是否过拟合。例如,训练集的准确率为90%,而测试集的准确率为70%,那么我们可以认为模型过拟合。不过,这种方法没有明确的判断标准,完全靠个人的主观判断——“感觉训练和测试的误差相差有点大,有可能过拟合”。 如何利用交叉验证避免过拟合? 避免模型过拟合的方法,总结大概以下几点:     - 重新清洗数据(删除稀疏特征、对噪声数据进行处理(删除/替换))   - 重新采样(改变采样方法等)   - 增加训练数据   - 采用交叉验证训练模型   - 重新筛选特征   - 降低模型复杂度(增加正则项:L1,L2)   - dropout(神经网络中,让神经元一定的概率不工作) 这里探讨如何利用交叉验证来避免模型过拟合: 第一个作用是对模型的性能进行评估 。当我们通过一次划分样本对模型进行训练和测试时,由于样本划分的偶然性,会导致我们对模型的评估不准确。因此,可以采用交叉验证对模型进行评估(一般采用5折或10折,sklearn默认采用的是3折),以 n 折交叉验证结果的均值,作为模型的性能评估。 第二个作用就是用来避免过拟合 。例如当我们进行10折交叉验证时,训练了10次,得到了10个模型,每个模型的参数也是不同的,那么我们究竟用哪个模型作为我们最终的模型呢?答案是: 一个都不用!我们要利用全量数据重新训练出一个最终模型! 关于实现ROC曲线的绘制,可通过多种途径进行,这里列出一些可操作平台和方法: 1、SPSS: 如何用SPSS做ROC曲线分析?看这1篇就够了! 2、R语言: R语言逻辑回归、ROC曲线和十折交叉验证                     ROC曲线基于R语言-(pROC包)                     R语言pROC包绘制ROC曲线 3、Python: 机器学习基础(1)- ROC曲线理解                     ROC原理介绍及利用python实现二分类和多分类的ROC曲线 4、Matlab: Matlab绘图——ROC曲线绘制(官方demo)                      ROC曲线详解及matlab绘图实例 ROC曲线的初步学习就到这里,我们初步了解到ROC曲线最初是用来评估雷达兵判断的轰炸机信号准确性的方法,随后沿用到了医学指标的判定上,在生活中应用广泛。ROC曲线可用于查出任意界限值时的对疾病的识别能力,选择最佳的诊断界限值,还可以用在评估机器学习预测模型的好坏上(目前好像这方面用的比较多)。当然,还有一些问题值得讨论,比如,何时需要使用ROC曲线,S折交叉验证平均ROC曲线如何绘制,等等。在机器学习模型构建过程中,训练集和测试集的建立,模型的交叉验证和ROC曲线评估的结合,还需要继续学习。 Kootte RS, Levin E, Salojärvi J, Smits LP, Hartstra AV, Udayappan SD, Hermes G, Bouter KE, Koopen AM, Holst JJ, Knop FK, Blaak EE, Zhao J, Smidt H, Harms AC, Hankemeijer T, Bergman JJGHM, Romijn HA, Schaap FG, Olde Damink SWM, Ackermans MT, Dallinga-Thie GM, Zoetendal E, de Vos WM, Serlie MJ, Stroes ESG, Groen AK, Nieuwdorp M.

ICH-GCP 3.1 Informed Consent(1)

Part 1: What is Informed Consent? Part 2: The Informed Consent DocumentWhen most people hear the phrase “informed consent,” they think of the legal document that explains the study and contains the required dated signatures. However, informed consent is first and foremost a continuing process. This includes a person voluntarily agreeing to participate in a research study after being fully informed about it via verbal discussion with study staff, followed by documentation in a written, signed, and dated informed consent form. A participant"s consent will be continually sought during the course of the study, and the participant will be notified of any changes to the study, along with any other pertinent information that may influence their decision to remain in the study. 当大多数人听到“知情同意”一词时,他们会想到解释该研究并包含所需日期签名的法律文件。然而 ,知情同意首先是一个持续的过程 。这包括通过与研究人员进行 口头讨论 ,并随后以 书面 、 签字 和 注明日期 的知情同意书形式记录, 自愿同意参与 研究的人员。在研究过程中,将 不断征求参与者的同意 ,并将研究的任何变更以及可能影响其继续参与研究决定的任何其他相关信息通知参与者。 While documentation of informed consent is required in most clinical studies, there are occasions when a waiver or alteration of written informed consent is obtained from the Institutional Review Board (IRB) for some or all study participants. The fundamental criteria for waivers and alterations of informed consent are located in 45 CFR 46.116(c) and 45 CFR 46.116(d). Please consult the local IRB for determining when it is appropriate to waive the requirement for written consent. 虽然在大多数临床研究中都需要知情同意书的文件记录, 但在某些情况下,一些或所有研究参与者的书面知情同意书会从机构审查委员会(IRB)处获得弃权或变更。 《美国联邦法规》第45卷第46.116(c)节和第45卷第46.116(d)节规定了放弃和变更知情同意书的基本标准。 请咨询当地IRB,以确定何时适合放弃书面同意的要求。 The informed consent document should contain all of the information that the person needs to make an informed decision about taking part in the study. Many research teams use the consent document to guide the verbal explanation of the study to potential participants. 知情同意书文件应包含患者做出参与研究知情决定所需的所有信息。许多研究团队使用同意书来指导 潜在参与者 对研究进行 口头解释 。 The participant must sign and date the informed consent document before taking part in any study procedures. Signing the consent form is NOT the final step in the informed consent process. The participant may withdraw consent and decline to participate in the study at any time before or after signing the consent document until their participation in the study is completed. 参与任何研究程序前,参与者必须在知情同意书上签字并注明日期。签署同意书并不是知情同意过程的最后一步。参与者可在签署同意书之前或之后的任何时间 撤回同意书 并 拒绝参与研究 ,直至其参与研究完成。 The general requirements for informed consent in federally funded research are spelled out in 45 CFR 46.116 and 21 CFR 50.20 . Some states have enacted requirements for informed consent that go beyond federal regulations. This module reviews the requirements for informed consent that are set out in federal regulations and in the Good Clinical Practice guidelines of the International Council for Harmonization (ICH GCP 4.8.10). It is the principal investigator"s responsibility to know and abide by any additional state requirements. 联邦资助研究中知情同意的一般要求在45 CFR 46.116和21 CFR 50.20中有详细说明。 一些州颁布了超出联邦法规的知情同意要求。 本单元审查联邦法规和国际协调理事会良好临床实践指南(ICH GCP 4.8.10)中规定的知情同意要求。主要调查员有责任了解并遵守任何其他州要求。 All researchers must ensure that the process of obtaining informed consent from study participants not only conforms to federal, state, and local regulations but also respects each individual"s right to make a voluntary, informed decision. 所有研究人员必须确保获得研究参与者知情同意的过程不仅 符合联邦、州和地方法规 ,而且 尊重每个人做出自愿知情决定的权利 。 Part 2 of this module deals with the informed consent document. Part 4 deals with the informed consent process. 本单元第2部分涉及知情同意书。第4部分涉及知情同意程序。The consent document must state (ICH GCP 4.8.10):    i、That the trial involves research.    ii、The purpose of the trial. 同意书必须说明(ICH GCP 4.8.10): (1) 试验涉及研究 。 (2) 试验的目的 。 The consent document must state (ICH GCP 4.8.10):  The trial treatment(s) and the probability for random assignment to each treatment (if a randomized clinical trial). 同意书必须说明(ICH GCP 4.8.10):  试验治疗和随机分配给每个治疗的概率 (如果是随机临床试验)。 The consent document must state (ICH GCP 4.8.10):    i、The trial procedures to be followed, including all invasive procedures.    ii、The participant"s responsibilities.    iii、Those aspects of the trial that are experimental.    iv、The expected duration of the participant"s involvement in the trial. 同意文件必须声明(ICH GCP 4.8.10): (1)应遵循的试验 程序 ,包括所有侵入性程序。 (2)参与者的 责任 。 (3)试验的那些方面是 实验性 的。 (4)受试者参与试验的 预期持续时间 。 The consent document must state (ICH GCP 4.8.10): The reasonably foreseeable risks or inconveniences to the participant and, when applicable, to an embryo, fetus, or nursing infant. 同意书必须说明(ICH GCP 4.8.10):对参与者和(如适用)胚胎、胎儿或哺乳期婴儿的合理可预见风险或不便。 The consent document must state (ICH GCP 4.8.10): The reasonably expected benefits. When there is no intended clinical benefit to the participant, the participant should be made aware of this. 同意文件必须说明(ICH GCP 4.8.10):合理预期的利益。当参与者没有预期的临床益处时,应让参与者意识到这一点。 The consent document must state (ICH GCP 4.8.10): The alternative procedure(s) or course(s) of treatment that may be available to the participant, and their important potential benefits and risks. Points to note: IRBs often want the informed consent document to list other therapies available for the condition under treatment in addition to other treatment options at the facility where the study is being conducted. 同意书必须说明(ICH GCP 4.8.10):参与者可以使用的替代治疗程序或疗程,及其重要的潜在益处和风险。 需要注意的要点: IRB通常希望知情同意书中列出治疗条件下的其他治疗方法,以及正在进行研究的设施中的其他治疗方案。 The consent document must state (ICH GCP 4.8.10):    i、The compensation and/or treatment available to the participant in the event of trial-related injury.    ii、The anticipated expenses, if any, to the participant for participating in the trial. Points to note: When research involves more than minimal risk to the participant, the consent document must describe the treatment and compensation that will be provided in the event that a participant sustains a research-related injury. The language in the consent cannot appear to limit the participant"s rights in seeking damages related to injury in a trial. Federal regulations do not limit the definition of “injury” to a physical injury. An injury may be psychological, social, financial, or of another nature. 同意书必须说明(ICH GCP 4.8.10): (1)在试验相关伤害事件中,参与者可获得的补偿和/或治疗。 (2)参与者参与试验的预期费用(如有)。 注意事项: 当研究对参与者的风险超过最低限度时,同意书必须说明参与者遭受研究相关伤害时将提供的治疗和补偿。同意书中的语言似乎不能限制参与人在审判中要求损害赔偿的权利。 联邦法规没有将“伤害”的定义限制为身体伤害。伤害可能是心理、社会、经济或其他性质的。 The consent document must state (ICH GCP 4.8.10): The anticipated prorated payment, if any, to the participant for participating in the trial. Points to note : Payment to participants for their participation in a research study must never be coercive in either amount or method of distribution. 同意书必须说明(ICH GCP 4.8.10):参与试验的参与者的预期 按比例付款 (如有)。 注意事项 :对参与研究的参与者的付款,无论是在金额上还是在分配方式上,都不能是强制性的。 The consent document must state (ICH GCP 4.8.10):    i、That the participant"s participation in the trial is voluntary and that the participant may refuse to participate or withdraw from the trial, at any time, without penalty or loss of benefits to which the participant is otherwise entitled.    ii、The foreseeable circumstances and/or reasons under which the participant"s participation in the trial may be terminated. 同意书必须说明(ICH GCP 4.8.10): (1)参与者参与试验是 自愿 的,参与者可以在任何时候拒绝参与或退出试验,而不会受到惩罚或损失参与者应有的利益。 (2)参与者可能终止参与试验的 可预见情况和/或原因 。 The consent document must state (ICH GCP 4.8.10):    i、That the monitor(s), the auditor(s), the IRB, and the regulatory authority(ies) will be granted direct access to the participant"s original medical records for verification of clinical trial procedures and/or data, without violating the confidentiality of the participant, to the extent permitted by the applicable laws and regulations and that, by signing a written informed consent form, the participant or the participant"s legal representative is authorizing such access.    ii、That records identifying the participant will be kept confidential and, to the extent permitted by the applicable laws and/or regulations, will not be made publicly available.

肿瘤突变高灵敏度NGS检测技术:挑战、进展和应用

  Next-generation sequencing (NGS) technologies have come of age as preferred technologies for screening of genomic variants of pathologic and therapeutic potential. Because of their capability for high-throughput and massively parallel sequencing, they can screen for a variety of genomic changes in multiple samples simultaneously. This has made them platforms of choice for clinical testing of solid tumors and hematological malignancies. Consequently, they are increasingly replacing conventional technologies, such as Sanger sequencing and pyrosequencing, expression arrays, real-time PCR, and fluorescence in situ hybridization methods, for routine molecular testing of tumors.   However, one limitation of routinely used NGS technologies is the inability to detect low-level genomic variants with high accuracy . This can be attributed to the frequent occurrence of low-level sequencing errors and artifacts in NGS workflow that need specialized approaches to be identified and eliminated.    In terms of NGS, LOD can be defined as the minor allelic frequency of a variant at which 95% of the samples tested will be detected reliably. In NGS, this can be potentially influenced by several factors. Consequently, it is not surprising that the reported LODs for a variety of NGS assays, including limited gene panels, whole exome sequencing, and whole genome sequencing, range from 2% to 15% variant allelic frequency (VAF).   Cancer is predominantly driven by somatic mutations, which can occur at any level in a sample because of tumor heterogeneity caused by co-existence of multiple mutations in the tumor cell or occurrence of multiple cancerous clones in the same tumor. Consequently, it is challenging to define an LOD as adequate for genomic screening of tumors. Considering that somatic mutations can manifest at any given level in a tumor sample, achieving progressively higher detection sensitivity (or lower LODs) will be crucial to improve tumor mutation screening. Although current NGS platforms routinely identify low-level mutations (<1% VAF), most are not equipped to distinguish them from spurious, low-level sequencing artifacts (false positives) that originate from various steps of NGS workflow.   However, most of the solid organ tumors and bone marrow biopsy samples are formalin fixed and paraffin embedded (FFPE). However, formalin fixation has detrimental effects on the integrity, extraction efficiency, and amplifiability of nucleic acids.   Furthermore, several parameters of formalin fixation and nucleic acid extraction processes have been identified to also adversely affect the quality of nucleic acids, and strategies to minimize them have been proposed.   Another routinely used method for preparation of DNA for NGS is sonication (acoustic shearing), which is used to generate DNA fragments of required size ranges. This process also generates low-level 8-oxoguanine lesions in DNA because of oxidation, resulting in G:C>T:A artifacts that compromise the accuracy and confidence of low-level variant detection.   Although highfidelity polymerases with error rates of one per million base pairs (error rate of 10 -6 ) are routinely used for the NGS workflow, using excessive PCR cycles and low-quality DNA with processing-induced chemical modifications compound the issue, resulting in sequencing artifacts.   In addition, polymerase-induced PCR errors during clonal amplifications of DNA strands (to isolate and amplify each DNA library strand for sequencing) and the actual sequencing by synthesis also contribute additional errors.   Not surprisingly, several studies investigating the role of polymerase fidelity have established improved accuracy of NGS by incorporating higher-fidelity polymerases, albeit to varying extents, depending on the target sequence and applications investigated. Furthermore, GC- and AT-rich genomic regions can also be underrepresented in the PCRdependent workflow, resulting in low sequencing coverage and compromised variant detection, especially gene copy number alterations.   Although all NGS platforms perform massively parallel sequencing, the underlying sequencing technologies are distinct. This results in intrinsic variations in major aspects, such as sequencing run time, sequencing output, read length, and error rates.   This represents a critical step in NGS workflow, which includes digital processing of the voluminous sequencing information generated by the sequencers to obtain meaningful genomic sequences and detect variants. It encompasses consolidation of raw signal information from the sequencer, base calling, elimination of low-quality base calls and sequencing reads using preset quality parameters, and alignment of sequence information obtained to a reference sequence to identify potential sequence variants.   However, this process could also be a source of sequence artifacts, which can originate at various steps involved.   Template tagging is a revolutionary breakthrough approach where each template DNA molecule is tagged by a unique synthetic DNA sequence and used to trace back the strands of origin for the variant detected.   Different studies using UIDs in NGS have reported highconfidence LODs, ranging from 0.01% to 1% VAF, which represents a significant improvement (by at least two orders of magnitude) in comparison to conventional NGS.   This is an improved version of the UID tagging approach, in which the DNA template is tagged by two distinct and random UIDs on either side, tagging both the strands of DNA (+ and - strands). Doing so, the mutations detected can be traced back to each individual strand of duplex DNA template after paired-end sequencing.   The use of UIDs comes with some drawbacks:   To circumvent this, some recent advances have used non-UID methods that can identify lowlevel variants with accuracy.   Although these methods represent significant improvements in non-UID options, their applicability in routine clinical laboratory workflow and performance to the expected standards of a clinical test are yet to be demonstrated.    Eliminating the clonal amplification step would be useful in eliminating these errors and is possible with sequencing technologies, which are referred to as single-molecule sequencing, where each original strand of DNA is sequenced individually.   Minimal residual disease (MRD) is defined as low-level remnant tumor content after complete remission, following surgery or therapeutic intervention, and is undetectable by routine histologic or radiological examinations. MRD represents cells from the original tumor that have not been cleared by treatment approaches and therapy-resistant subclones.   MRD monitoring is more prevalent in hematological cancers because of the ease of obtaining blood samples and is performed using sensitive techniques, like flow cytometry and ASPCR. Consequently, MRD levels are also defined by the LOD of these techniques, which is generally 0.01% (1 tumor cell in the background of 10,000 normal cells). However, these methods are restricted to screening a limited number of known markers and are not helpful in preemptively detecting emergent malignant clones.   NGS with the unique capability to screen multiple markers simultaneously can fulfill this need. In recent years, several studies have established the ability of NGS in MRD detection.74,75 However, routine MRD evaluation by NGS has been hindered because of the difficulties in detecting and authenticating low-level mutations (especially SNVs), cost, and long turnaround time. Consequently, MRD detection by NGS has been recommended for clinical trials only.   Recently developed, error-corrected NGS technologies have made NGS more attractive for routine MRD estimation.   The overall levels of cell-free DNA are also observed to be more in cancer because of the relatively higher cell growth and necrosis in tumors compared with healthy tissues.   Studies have shown concordance of the mutation profiles of ctDNA and tumor along with a direct correlation of ctDNA with the tumor burden and the stage of the tumor. Consequently, isolation and screening of cell-free DNA as a surrogate for DNA directly isolated from tumor tissue is an attractive proposition. This approach is especially valuable for solid tumors, where acquiring a tumor sample requires surgical resection or methods such as core-needle or fine-needle biopsies.

英语流利说 Level8 Unit3 Part1:Evolving Our Bodies

Juan Enriquez: What will humans look like in 100 years | TED Talk Here"s a question that matters. Right? Because we"re beginning to get all the tools together to evolve ourselves.  And we can evolve bacteria and we can evolve plants and we can evolve animals,  and we"re now reaching a point where we really have to ask, is it really ethical and do we want to evolve human beings?  And as you"re thinking about that, let me talk about that in the context of prosthetics, prosthetics past, present, future. So this is the iron hand that belonged to one of the German counts.  Loved to fight, lost his arm in one of these battles.  No problem, he just made a suit of armor, put it on, perfect prosthetic.  That"s where the concept of ruling with an iron fist comes from.  And of course these prosthetics have been getting more and more useful, more and more modern. You can hold soft-boiled eggs.  You can have all types of controls, and as you"re thinking about that,  there are wonderful people like Hugh Herr who have been building absolutely extraordinary prosthetics.  So the wonderful Aimee Mullins will go out and say, how tall do I want to be tonight?  Or he will say what type of cliff do I want to climb?  Or does somebody want to run a marathon, or does somebody want to ballroom dance?  And as you adapt these things, the interesting thing about prosthetics is they"ve been coming inside the body.  So these external prosthetics have now become artificial knees. They"ve become artificial hips.  And then they"ve evolved further to become not just nice to have but essential to have. So when you"re talking about a heart pacemaker as a prosthetic,  you"re talking about something that isn"t just, " I"m missing my leg,"  it"s, "if I don"t have this, I can die."  And at that point, a prosthetic becomes a symbiotic relationship with the human body. How have  prosthetics evolved over time? They"ve become more customizable and necessary. Why does Enriquez believe prosthetics have the common ethical issue? They have the ability to radically change the human body. A symbiotic relationship is one in which both sides depend on each other for survival. And four of the smartest people that I"ve ever met -- Ed Boyden, Hugh Herr, Joe Jacobson, Bob Lander -- are working on a Center for Extreme Bionics.  And the interesting thing of what you"re seeing here is these prosthetics now get integrated into the bone. They get integrated into the skin. They get integrated into the muscle.  And one of the other sides of Ed is he"s been thinking about how to connect the brain using light or other mechanisms directly to things like these prosthetics.  And if you can do that, then you can begin changing fundamental aspects of humanity.  So how quickly you react to something depends on the diameter of a nerve.  And of course, if you have nerves that are external or prosthetic, say with light or liquid metal,  then you can increase that diameter and you could even increase it theoretically to the point where,  as long as you could see the muzzle flash, you could step out of the way of a bullet.  Those are the order of magnitude of changes you"re talking about. This is a fourth sort of level of prosthetics. These are Phonak hearing aids,  and the reason why these are so interesting is because they cross the threshold from where prosthetics are something for somebody who is " disabled "  and they become something that somebody who is "normal" might want to actually have,  because what this prosthetic does, which is really interesting, is not only does it help you hear ,  you can focus your hearing, so it can hear the conversation going on over there.  You can have superhearing. You can have hearing in 360 degrees. You can have white noise. You can record, and oh, by the way, they also put a phone into this.  So this functions as your hearing aid and also as your phone.  And at that point, somebody might actually want to have a prosthetic voluntarily. All of these thousands of loosely connected little pieces are coming together ,  and it"s about time we ask the question, how do we want to evolve human beings over the next century or two?  And for that we turn to a great philosopher  who was a very smart man despite being a Yankee fan. And Yogi Berra used to say, of course, that it"s very tough to make predictions, especially about the future.How can prosthetic nerves affect help people to react things? They can be designed to optimize human reaction speed. What role does  Enriquez think prosthetic will have in the future? He isn"t completely sure about their role. When prosthetics become this advanced, somebody might actually want to have one voluntarily.  So instead of making a prediction about the future to begin with, let"s take what"s happening in the present with people like Tony Atala,  who is redesigning 30-some-odd organs.  And maybe the ultimate prosthetic isn"t having something external, titanium. Maybe the ultimate prosthetic is take your own gene code,  remake your own body parts, because that"s a whole lot more effective than any kind of a prosthetic.  But while you"re at it, then you can take the work of Craig Venter and Ham Smith.  And one of the things that we"ve been doing is trying to figure out how to reprogram cells.  And if you can reprogram a cell, then you can change the cells in those organs.  So if you can change the cells in those organs, maybe you make those organs more radiation-resistant. Maybe you make them absorb more oxygen. Maybe you make them more efficient to filter out stuff that you don"t want in your body.  And over the last few weeks, George Church has been in the news a lot  because he"s been talking about taking one of these programmable cells and inserting an entire human genome into that cell.  And once you can insert an entire human genome into a cell, then you begin to ask the question, would you want to enhance any of that genome?  Do you want to enhance a human body?  How would you want to enhance a human body?  Where is it ethical to enhance a human body and where is it not ethical to enhance a human body?  And all of a sudden, what we"re doing is we"ve got this multidimensional chess board  where we can change human genetics by using viruses to attack things like AIDS,  or we can change the gene code through gene therapy to do away with some hereditary diseases, or we can change the environment,  and change the expression of those genes in the epigenome and pass that on to the next generations.  And all of a sudden , it"s not just one little bit, it"s all these stacked little bits  that allow you to take little portions of it until all the portions coming together lead you to something that"s very different.Why is  Enriquez  concerned about genetic prosthetics? They could change the human species radically but unpredictably. What is an example of a cell-based prosthetic? changing an organ to make it resistant radiation And a lot of people are very scared by this stuff.  And it does sound scary, and there are risks to this stuff.  So why in the world would you ever want to do this stuff?  Why would we really want to alter the human body in a fundamental way? The answer lies in part with Lord Rees, astronomer royal of Great Britain.  And one of his favorite sayings is the universe is 100 percent malevolent.  So what does that mean? It means if you take any one of your bodies at random, drop it anywhere in the universe, drop it in space, you die.  Drop it on the Sun, you die. Drop it on the surface of Mercury, you die. Drop it near a supernova, you die.  But fortunately, it"s only about 80 percent effective.  So as a great physicist once said, there"s these little upstream eddies of biology that create order in this rapid torrent of entropy.  So as the universe dissipates energy, there"s these upstream eddies that create biological order.  Now, the problem with eddies is, they tend to disappear. They shift. They move in rivers.  And because of that, when an eddy shifts, when the Earth becomes a snowball, when the Earth becomes very hot, when the Earth gets hit by an asteroid,  when you have supervolcanoes, when you have solar flares,  when you have potentially extinction-level events like the next election -- then all of a sudden, you can have periodic extinctions.  And by the way, that"s happened five times on Earth,  and therefore it is very likely that the human species on Earth is going to go extinct someday.  Not next week, not next month, maybe in November, but maybe 10,000 years after that.  As you"re thinking of the consequence of that,  if you believe that extinctions are common and natural and normal and occur periodically,  it becomes a moral imperative to diversify our species.  And it becomes a moral imperative because  it"s going to be really hard to live on Mars if we don"t fundamentally modify the human body. Right?  You go from one cell, mom and dad coming together to make one cell, in a cascade to 10 trillion cells.  We don"t know, if you change the gravity substantially, if the same thing will happen to create your body.  We do know that if you expose our bodies as they currently are to a lot of radiation, we will die.  So as you"re thinking of that, you have to really redesign things just to get to Mars.  Forget about the moons of Neptune or Jupiter. What does Enriquez mean when he says the universe is 100 percent malevolent? Humans can"t survive anywhere other than Earth. According to Enriquez  what is a moral imperative for the human race?  using prosthetics to enhance the human species If human beings want to live on Mars they will need to modify their bodies to survive. And to borrow from Nikolai Kardashev, let"s think about life in a series of scales.  So Life One civilization is a civilization that begins to alter his or her looks.  And we"ve been doing that for thousands of years.  You"ve got tummy tucks and you"ve got this and you"ve got that.  You alter your looks and I"m told that not all of those alterations take place for medical reasons. Seems odd. A Life Two civilization is a different civilization.  A Life Two civilization alters fundamental aspects of the body.  So you put human growth hormone in, the person grows taller, or you put x in and the person gets fatter or loses metabolism or does a whole series of things,  but you"re altering the functions in a fundamental way.  To become an intrasolar civilization, we"re going to have to create a Life Three civilization,  and that looks very different from what we"ve got here.  Maybe you splice in Deinococcus radiodurans so that the cells can resplice after a lot of exposure to radiation.  Maybe you breathe by having oxygen flow through your blood instead of through your lungs.  But you"re talking about really radical redesigns  and one of the interesting things that"s happened in the last decade is we"ve discovered a whole lot of planets out there.  And some of them may be Earth-like.  The problem is, if we ever want to get to these planets, the fastest human objects  -- Juno and Voyager and the rest of this stuff -- take tens of thousands of years to get from here to the nearest solar system.  So if you want to start exploring beaches somewhere else,  or you want to see two-sun sunsets, then you"re talking about something that is very different,  because you have to change the timescale and the body of humans in ways which may be absolutely unrecognizable.  And that"s a Life Four civilization.How does  Enriquez describe a life one civilization? People begin to modify their appearance. What the humans need to do if they want to reach distance planets and solar systems? change how human bodies age over long periods of time In order to develop an intrasolar civilization, humans would have to modify the body to allow long-distance space travel. In a life two civilization, people can use growth hormones to change fundamental aspects of the body . Now, we can"t even begin to imagine what that might look like, but we"re beginning to get glimpses of instruments that might take us even that far.  And let me give you two examples. So this is the wonderful Floyd Romesberg,  and one of the things that Floyd"s been doing is he"s been playing with the basic chemistry of life.

求个美国白宫资料,英文的

The White House is the official residence and principal workplace of the President of the United States. Located at 1600 Pennsylvania Avenue NW in Washington, D.C., the house was designed by Irish-born James Hoban,and built between 1792 and 1800 of white-painted Aquia sandstone in the Neoclassical style. It has been the residence of every U.S. President since John Adams. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) expanded the building outward, creating two colonnades that were meant to conceal stables and storage.In 1814, during the War of 1812, the mansion was set ablaze by the British Army in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began almost immediately, and President James Monroe moved into the partially reconstructed house in October 1817. Construction continued with the addition of the South Portico in 1824 and the North in 1829. Because of crowding within the executive mansion itself, President Theodore Roosevelt had all work offices relocated to the newly constructed West Wing in 1901. Eight years later, President William Howard Taft expanded the West Wing and created the first Oval Office which was eventually moved as the section was expanded. The third-floor attic was converted to living quarters in 1927 by augmenting the existing hip roof with long shed dormers. A newly constructed East Wing was used as a reception area for social events; Jefferson"s colonnades connected the new wings. East Wing alterations were completed in 1946, creating additional office space. By 1948, the house"s load-bearing exterior walls and internal wood beams were found to be close to failure. Under Harry S. Truman, the interior rooms were completely dismantled and a new internal load-bearing steel frame constructed inside the walls. Once this work was completed, the interior rooms were rebuilt.Today, the White House Complex includes the Executive Residence, West Wing, Cabinet Room, Roosevelt Room, East Wing, and the Eisenhower Executive Office Building, which houses the executive offices of the President and Vice President.The White House is made up of six stories—the Ground Floor, State Floor, Second Floor, and Third Floor, as well as a two-story basement. The term White House is regularly used as a metonym for the Executive Office of the President of the United States and for the president"s administration and advisers in general. The property is a National Heritage Site owned by the National Park Service and is part of the President"s Park. In 2007, it was ranked second on the American Institute of Architects list of "America"s Favorite Architecture".

商务英语写作格式

商务英语写作格式   现在许多公司都有外贸的生意,所以对商务英语写作息息相关。以下列举了商务英语写作的格式,希望你可以引以为戒:   1、 切忌主客不分或模糊。例子: Deciding to rescind the earlier estimate, our report was updated to include $40,000 for new equipment. 应改为 Deciding to rescind our earlier estimate, we have updated our report to include $40,000 for new equipment. (是We 来decide, 不是report.)   2、句子不要零碎。例子: He decided not to audit the last ten contracts, because of our previous objections about compliance. 应该连在一起.   3、对称的结构比较容易让人理解。例子: The owner questioned the occupant"s lease intentions and the fact that the contract had been altered with ink markings. 应改为: The owner questioned the occupant"s lease intentions and ink alterations of the contract.   4、 单复数不要搞乱,不然会好刺眼,看着不舒服。例如: An authorized person must show that they have security clearance.   5、 动词主词要呼应。 想想这两个分别:   1). This is one of the public-relations functions that are under budgeted.   2). This is one of the public-relations functions, which are under budgeted.   6、 时态和语气不要转变太多。看商务英语已经是苦事,不要浪费人家的精力啊。   7、标点要准确。例如: He did not make repairs, however, he continued to monitor the equipment.改为: He did not make repairs; however, he continued to monitor the equipment.   8、选词要正确,像affect和effect,operative和operational等等就要弄清楚才好用啦。   9、拼写要正确,有电脑拼字检查功能后,就更加不能偷懒。也许一笔好买卖就因为你的`一个错字飞掉了哦!   10、 大小写要注意。非必要不要整个字都是大写,除非要骂人。例如: MUST change to OS immediately. 外国人就觉得不礼貌和喝令人一样。要强调的话,用底线,斜字,粗体就可以了。   学会商务英语写作对于与外国人沟通也有关系的,因为商务英语写作是根据外国人的习惯来写的。 ;

关于电视带来的不良影响的英语作文

这是一篇电脑对儿童脑部影响的素材Watching too much television can change the structure of a child"s brain in a damaging way, according to a new study.Researchers found that the more time a child spent viewing TV, the more profound the brain alterations appeared to be.The Japanese study looked at 276 children aged between five and 18, who watched between zero and four hours TV per day, with the average being about two hours.MRI brain scans showed children who spent the most hours in front of the box had greater amounts of grey matter in regions around the frontopolar cortex - the area at the front of the frontal lobe.But this increased volume was a negative thing as it was linked with lower verbal intelligence, said the authors, from Tohoku University in the city of Sendai.They suggested grey matter could be compared to body weight and said these brain areas need to be pruned during childhood in order to operate efficiently.‘These areas show developmental cortical thinning during development, and children with superior IQs show the most vigorous cortical thinning in this area," the team wrote.They highlighted the fact that unlike learning a musical instrument, for example, programmes we watch on TV ‘do not necessarily advance to a higher level, speed up or vary".‘When this type of increase in level of experience does not occur with increasing experience, there is less of an effect on cognitive functioning," they wrote.Children who watch the most TV have the most profound changes to their brain structureThe authors said the impact of watching TV on the ‘structural development" of the brain has never before been investigated.‘In conclusion, TV viewing is directly or indirectly associated with the neurocognitive development of children," they wrote.‘At least some of the observed associations are not beneficial and guardians of children should consider these effects when children view TV for long periods of time."The children in the study were an almost even split between girls and boys.The findings, published in the journal Cerebral Cortex, highlighted an association between TV viewing and changes in the brain but do not prove that TV definitely caused the changes.Scientists also cannot be sure whether missing out on activities such as reading, playing sports or interacting with friends and family as a result of watching TV could be behind the findings, rather than TV being directly to blame.But they did say that the frontopolar cortex area of the brain has previously been associated with ‘intellectual abilities".

简答:血尿屏障的结构和功能

Blood–urine barrier, which is formed during differentiation of superficial urothelial cells, is the tightest and most impermeable barrier in the body. In the urinary bladder, the barrier must accommodate large changes in the surface area during distensions and contractions of the organ. Tight junctions and unique apical plasma membrane of superficial urothelial cells play a critical role in the barrier maintenance. Alterations in the blood–urine barrier function accompany most of the urinary tract diseases. In this review, we discuss recent discoveries on the role of tight junctions, dynamics of Golgi apparatus and post-Golgi compartments, and intracellular membrane traffic during the biogenesis and maintenance of blood–urine barrier. 徐涵 摘自Protoplasm 2010 Review ArticleFormation and maintenance of blood–urine barrier in urothelium By: Mateja Erdani Kreft, Samo Hudoklin, Kristijan Jezernik and Rok Romih

Daddy is ill.我很着急,我爸爸病了。3) 用作定语:She had a worried look on her face. 他满面愁容。4) 构成复合宾语:She wanted the work finished by Friday. 他要求这工作星期五前完成。5) 作状语:Aroused by the crash, he leapt to his feet. 他被撞击声惊醒,一跃站起身来。过去分词只有一种形式,在大多数时候下都有被动的意思。2、过去分词作表语编辑本段回目录 1) 过去分词作表语的时候很多(其中有很多已变成形容词):He was amazed and enchanted at the sight. 看到这情景他感到惊异着迷。She was annoyed at your saying that. 你这样讲她很不高兴。We were so bored that we couldn"t help yawning. 我们烦得要命禁不住打哈欠。They were very pleased with the girl. 他们很喜欢这姑娘。I am afraid I"m slightly drunk. 可能我有一点醉了。I"m obliged to you for all you"ve done for us. 我很感激你为我们所做的一切。The couple were devoted to each other. 这对夫妻十分恩爱。2)这种结构和被动语态是有差别的,“be+表语”结构表示一种状态,而被动语态表示一个动作,比较下面句子:be+表语结构(表示状态) 被动语态(表示动作)the shop is closed now. it"s usually closed at 8 o"clock.The town is surrounded by hills.
