D - gal 属于己醛糖的一种,它与葡萄糖是同分 异构体。在机体的代谢过程中转变为葡萄糖供机体 使用,但若供给过多,则会使体内糖代谢紊乱,细胞渗 透压发生改变,导致细胞肿胀。同时 D - gal 在代谢 过程中还会生成大量的自由基,自由基在体内堆积, 进而损伤机体,加速机体衰老[8 - 10]。本试验结果表 明,一定剂量的 D - gal 能成功制造免疫衰老模型,为 衰老和抗衰老研究提供理论依据。
2 月龄健康昆明小鼠随机分为 2 组,每组 10 只, 雌雄各半,分别为青年对照组和衰老模型组。2 岁龄 健康小鼠为自然衰老组。购进后先饲喂 1 周减少应 激,适应环境后开始试验。青年对照组和自然衰老组 在颈背部注射生理盐水; 模型衰老组在颈背部注射 D - gal( 125 mg / kg) 制造衰老模型。持续 45 d。 2. 2 小鼠行为学检测( 跳台检测)
由表 2 可知: 衰老模型组与青年对照组比较,胸 腺、脾脏脏器指数降低,差异极显著( P < 0. 01) ; 衰老 模型组与自然衰老组比较,脾脏脏器指数差异不显著 ( P > 0. 05) ,胸腺脏器指数差异显著( P < 0. 05) 。 3. 3 生化指标检测结果

替罗非班桥接双抗治疗醒后卒中的疗效及安全性研究
【摘要】目的探讨早期应用替罗非班桥接阿司匹林和氯吡格雷双抗治疗超时间窗的醒后卒中患者的安全性及有效性。
方法选取潍坊医学院附属医院2018-01—2020-01收治的醒后卒中患者112例为研究对象,依据随机数表法分为对照组和观察组,对照组(n =56)接受氯吡格雷和拜阿司匹林治疗,观察组(n =56)接受替罗非班桥接双抗治疗,比较2组患者治疗前后神经功能评分(采用美国国立卫生研究院卒中量表评分)、评价预后功能的改良Rankin 量表(mRS )评分及不良事件(出血及死亡)。
结果2组治疗后NIHSS 评分较治疗前下降,治疗组下降更明显,差异有统计学意义(P <0.05);观察组的预后良好比例(mRS ≤2.0)较对照组明显增多,差异有统计学意义(P <0.05);观察组总有效率较对照组明显增高,差异有统计学意义(P <0.05);在出血、死亡等不良反应方面,2组相比差异无统计学意义(P >0.05)。
结论替罗非班桥接双抗治疗醒后卒中是一种安全有效的治疗策略。

环状rna注释
环状rna注释环状RNA(Circular RNA,circRNA),是一种新兴的内源性非编码RNA,是继microRNA以及long noncoding RNA后非编码RNA 家族中极具研究潜力的新成员。
近年来,随着RNA研究技术的进步,研究者们在多种生物中发现了数量众多的环状RNA,且发现它们具有重要的生物学功能,例如作为天然小RNA海绵体吸附并调控miRNA的活性,与转录调控元件结合或与蛋白互作调控基因的转录等。
已有研究表明,环状RNA与糖尿病、神经系统疾病、心血管疾病和癌症等疾病有关,因此具有重要的研究价值。
此外,环状RNA 的广泛表达和疾病调控机制使其成为多种疾病的功能生物标志物和治疗靶点。
一、环状RNA的生物发生及特征环状RNA是一类特殊的非编码RNA分子,与传统的线性RNA不同,circRNA分子呈封闭环状结构,不受RNA外切酶影响,表达更稳定,不易降解。
环状RNA的生物发生过程包括以下几个阶段:1.转录:环状RNA的转录过程与线性RNA相似,由RNA聚合酶催化合成初级转录本。
2.剪接:初级转录本经过剪切酶的作用,去除内含子,连接外显子,形成环形RNA。
3.稳定化:环状RNA分子在细胞内稳定存在,不易被降解,主要通过抑制RNA外切酶活性来实现。
4.功能调控:环状RNA具有多种生物学功能,例如调控基因表达、作为miRNA海绵体等。
二、环状RNA的鉴定方法随着高通量测序技术的发展,环状RNA的鉴定方法得到了极大的改进。
目前,常用的环状RNA鉴定方法主要包括以下几种:1.高通量测序:通过RNA-seq技术,可大规模地鉴定环状RNA 分子。
将RNA-seq数据与参考基因组比对,识别出环状RNA的位置和结构。
2.生物信息学方法:基于环状RNA的特点,开发了一系列生物信息学方法,如find_circ、CIRCexplorer等,用于预测和鉴定环状RNA。
3.实验验证:通过实时荧光定量PCR(qPCR)、Northern blot 等方法,验证环状RNA的表达。
脑底动脉环名词解释
脑底动脉环名词解释脑底动脉环(Circle of Willis)是一个位于大脑底部的循环系统,由五个主要动脉组成,它们彼此相连,形成了一个环状的血管网络。
这个结构在大脑血液循环中起着重要的作用。
脑底动脉环包括以下五个主要组成部分:1. 前交通动脉(Anterior Communicating Artery,ACA):位于脑前部,连接了两侧大脑动脉的前部分。
2. 两侧大脑动脉(Middle Cerebral Arteries,MCA):从颈动脉分支而来,沿着大脑侧面向上延伸,为大脑提供了大部分的供血。
3. 内侧脑动脉(Posterior Communicating Arteries,PCoA):连接前交通动脉与后脑动脉。
4. 两侧后循环脑动脉(Posterior Cerebral Arteries,PCA):从椎动脉分支而来,负责为大脑后部供血,包括颞叶、枕叶和大脑脚。
5. 椎动脉(Vertebral Arteries):从颈椎的脊骨上缘进入颅内,沿着脊髓后外侧走向延伸至脑干的基部,向上延伸到脑底。
椎动脉是大脑血供的两个重要来源之一。
脑底动脉环的主要功能是保证大脑各个部分得到充足的血液供应。
由于大脑的多个动脉互相连接,所以即使某个动脉发生堵塞或者狭窄,血液仍然能够通过其他动脉来继续供应相应区域的脑组织。
这种互相补偿的机制可以减轻由于缺血引起的神经功能缺失。
此外,脑底动脉环还可以调控大脑血管的扩张和收缩,以及调节血压变化。
这有助于维持大脑血流动力学的稳定性,并在某些情况下防止异常血压引起的脑血管破裂。
虽然脑底动脉环在适应血流改变方面具有一定的能力,但它并不是一个完全闭合的环。
一些人可能由于遗传因素或其他原因而缺乏完全形成脑底动脉环的一部分,这会增加他们发生脑血管意外(如脑梗塞、脑出血等)的风险。
总之,脑底动脉环是一个位于大脑底部的血管环状结构,由五个主要动脉组成。
它在大脑血液循环中起着重要的作用,不仅为大脑提供血液供应,还可以补偿某些动脉阻塞或狭窄所导致的血液不足,并且有调节血压变化的功能。
生信环状rna8编号转换
生信环状rna8编号转换
生物信息学中的环状RNA(circRNA)通常以不同的方式进行编号转换,具体取决于你所使用的数据库或工具。
一种常见的方法是使用基因或转录本的Ensembl ID或基因名称来进行编号转换。
你可以使用Ensembl数据库或NCBI的Gene数据库来获取相关信息并进行转换。
另外,一些生物信息学工具和软件也提供了方便的编号转换功能,例如UCSC Genome Browser、circBase和circRNADb等数据库和工具。
这些工具可以帮助你将circRNA的编号从一种格式转换为另一种格式,例如从基因名称到Ensembl ID,或者从Ensembl ID到NCBI Gene ID等。
在进行编号转换时,确保使用最新的数据和信息,以确保准确性和一致性。
同时,要注意不同数据库和工具之间的命名规范和数据格式可能会有所不同,因此在进行转换时要仔细核对和验证结果。
希望这些信息能够帮助你进行circRNA的编号转换工作。
搞懂环状RNA(circRNA),看这篇就够了
搞懂环状RNA(circRNA),看这篇就够了环状RNA的定义是什么?circRNAs(Circular RNAs,环形RNA分子)是一类不具有5' 末端帽子和3' 末端poly(A)尾巴、并以共价键形成环形结构的非编码RNA分子。
环状RNA研究的历史?1971年。
研究者在马铃薯纺锤块茎病的研究中,发现类病毒(Viroids)能侵染植株并导致死亡。
与病毒不同的是,类病毒没有蛋白质外壳包被,基因组是单链、闭合、RNA分子。
1979年洛克菲勒大学的Hsu和Coca-Prados在电子显微镜下观察到的真核细胞细胞质中观测到环状RNA的存在。
1993年在小鼠精子决定基因Sry中发现环状转录。
2006年在果蝇中发现来自于Muscleblind的未知环状转录本。
2012年,Salzman通过RNA-Seq方法首次报道了~80个环状RNA。
至此借助于高通量测序技术,环状RNA(circular RNA)验明正身进入科研视界。
大量的circRNA分子被相继发现,Jeck 等在人类成纤维细胞中检测出了高达 25000 多种的circRNA;而Memczak等通过RNA-seq 数据结合人白细胞数据库鉴定出 1950种人类circRNA、1903种小鼠circRNA (其中81种与人类circRNA相同) 和724种线虫circRNA。
虽然circRNA大规模研究时间不长,但重量级文章陆续在NSC等期刊上发表,研究热潮已然升起。
环状RNA主要有哪些类型?目前发现的circRNA主要来源于基因外显子,但多项研究也表明circRNA的类型比想象的要复杂,可以来自基因组上多种基因结构。
同一基因位置可以产生不同类型的环状RNA环状的RNA主要特征有哪些?(1)circRNA由特殊的可变剪切产生,大量存在于真核细胞的细胞质中,但少部分内含子来源的circRNA则存在于核酸内,具有一定的组织、时序和疾病特异性;(2)广泛存在于人体细胞中,有时甚至超过它们线性异构体的10倍之多;(3)与传统的线型RNA(linear RNA,含5'和3'末端)不同,circRNA分子呈封闭环状结构,不易被核酸外切酶RNaseR降解,比线性RNA更稳定;(4)具有高度保守性,部分具有快速的进化性改变;(5)大多数来源于外显子,少部分由内含子直接环化形成;(6)部分circRNA分子含miRNA应答元件(miRNAresponse element,MRE),可充当竞争性内源RNA(competing endogenousRNA,ceRNA),与miRNA结合,在细胞中起到miRNA海绵的作用,进而解除miRNA对其靶基因的抑制作用,上调靶基因的表达水平;(7)可以翻译成蛋白质,但大部分是非编码RNA。

【摘要】三阴乳腺癌(TNBC)是乳腺癌中恶性程度最高的亚型,其特征为不表达雌激素受体、孕激素受体和人表皮生长因子受体2。
TNBC具有易侵袭和转移、预后不良、对常规化疗或靶向治疗效果不佳的临床特点。
研究表明,环状RNA(circRNA)在TNBC组织表达异常,并与TNBC患者的临床病理特征和预后相关。
circRNA可通过调控转录和剪接、作为微小RNA海绵、与蛋白质结合以及作为翻译模板,参与TNBC肿瘤细胞增殖、转移和耐药过程。
因此,circRNA在TNBC的早期诊断、临床治疗和预后监测方面有广泛的应用前景。
本文阐述了circRNA的形成和作用机制,并总结了circRNA在TNBC中的生物学功能和临床意义。

【摘要】环状RNA(CircRNA)广泛参与人类疾病的进程,其突变和失调与许多人类疾病密切相关.因此,建立一个高效准确的CircRNA与疾病之间的预测算法对于提前对疾病的发生做出预防以及发病后的治疗方案具有重要意义.提出了一种新的基于图神经网络和随机森林的算法预测CircRNA-疾病关联算法,在分层网络表示嵌入部分通过构建异构网络,根据网络图的邻近性,对网络图的节点和边缘进行分层,递归地合并原始图中的节点和边,得到若干具有相似特征的较小子网络.子网络规模随着分层的深入而递减,直至得到最小子网络后,使用node2vec网络图游走算法对其进行预处理,然后将全部节点的特征向量输入至随机森林分类器来识别潜在的CircRNA-疾病关联,从而进行预测.
