Studies on the Thermotolerant Related Genes of Agaricus Bisporus [PDF]

open access: yes, 2013
双孢蘑菇是高经济价值和生态意义的栽培食用菌。在许多因素中,温度是影响其栽培的主要因素。双孢蘑菇02菌株是一株耐热菌株,可在25℃~28℃下栽培;而8213菌株是一株普通菌株,只能在16℃~22℃下栽培。目前02菌株耐热的本质尚不清楚。本实验室通过构建的两个抑制性消减杂交文库I(02热胁迫vs.8213热胁迫)和II(02热胁迫vs.02非热胁迫)获得一批耐热相关基因的EST序列。本文对一些候选EST序列进行了以下研究:首先,通过cDNA末端快速扩增技术克隆EST序列1F6,1F146,First8 ...

A multicentric intermediate‐size B‐cell lymphoma with epitheliotropism in a Freiberger mare

open access: yesVeterinary Dermatology, Volume 35, Issue 5, Page 573-577, October 2024.
This report describes a multicentric intermediate‐size B‐cell lymphoma with epitheliotropism in a Freiberger mare affecting multiple mucous membranes, skin and internal organs. The clonal neoplastic B‐cell population was accompanied by numerous reactive polyclonal small T cells. Differential diagnoses for these unusual findings are discussed.

Construction and preliminary application of human naïve phage antibody library [PDF]

open access: yes, 2004
治疗性抗体在临床的应用已从30年代的抗血清时代经由80年代后的单克隆抗体时代进入到今天的基因工程抗体时代。目前处于各期临床的生物新药中,基因工程抗体是最多的一类,显示出治疗性抗体具有广阔的临床应用前景,而人源抗体是治疗性抗体的发展趋势。人源性噬菌体抗体库技术解决了人源性单抗来源困难、人体杂交瘤系统低效及鼠单抗的动物源性难题,是分子生物学和免疫学领域中一个强有力的研究手段。本研究从20例未经免疫的健康人的外周血中分离出淋巴细胞,提取总RNA并纯化出mRNA,然后反转录成cDNA ...

Preparation of monoclonal antibodies against mouse alpha-fetoprotein and preliminary study on their application [PDF]

open access: yes, 2016
原发性肝癌是我国高发的恶性肿瘤之一,每年新发和死亡患者均占全球总数的一半以上。根据全国肿瘤登记中心最新公布的2015年《肿瘤登记年报》数据,我国肝癌新增病例为46.61万,占所有恶性肿瘤的第4位(10.86%),而死亡病例为42.21万,占所有癌症死亡的第3位(15.00%),仅次于肺癌和胃癌。尽管近年来肝癌的诊断和治疗有了一定的进展,其预后仍然不理想,五年生存率极低。究其原因,大部分肝癌患者往往在疾病的晚期才被诊断出来,有些甚至发生了远端转移,因而错过了最佳治疗时机;此外 ...

Characterization and cloning and expression of Polyphenol Oxidase (PPO) from Canarium album [PDF]

open access: yes, 2016
多酚氧化酶(EC.1.14.18.1)广泛存在于动物、植物和微生物体内,是一种由核基因编码的含铜金属酶。它是果蔬储藏和加工过程中酶促褐变的重要酶类,能够催化酚类物质的氧化。以橄榄(长营)为原料提取多酚氧化酶进行了分离纯化,得到比活力为1834U/mg的多酚氧化酶粗酶液。研究橄榄多酚氧化酶的理化性质,酶的pH和最适温度分别为6.0和30℃,酶在低于60℃和在pH4.0~8.0范围内较稳定;在30℃、pH6.0条件下,多酚氧化酶催化L-DOPA氧化反应的Km为3.884mmol/L ...

摘 要 砷及其衍生物广泛分布自然环境并对人类健康构成危害。虽然流行病学研究已经证实长期的砷暴露能诱发多种癌症,但对砷致癌的确切机制目前远未被阐明,需要进一步深入地探索。砷诱导肿瘤形成是一个长期和复杂的过程,相关研究工作首先需要一个合适的细胞模型。为此,我们以低浓度亚砷酸钠长时间处理正常的大鼠肺上皮细胞系(LECs)诱导其转化,再通过一系列的指标实验验证,成功地建立砷转化细胞模型TLECs(Arsenite-transformedLECs),从而为下一步的研究奠定基础 ...

New Devices for Droplet Generation and Their Application in Single-Molecule Amplification and Single Cell Manipulation [PDF]

open access: yes, 2016
单分子、单细胞是生物体系的最基本单位。分子之间的不同决定了其引发反应的不同,细胞之间的不同决定了生命活动的不同。因此,深入研究单分子和单细胞对人们探索生命活动本质是十分必要的。与传统研究对象不同,单个分子、单个细胞的研究需要更加精准的研究平台,从而避免大背景的干扰,提高信噪比。微流控芯片,是一种将常规反应小型化、集成化新型的技术。其具有反应迅速、反应体积小、信噪比高、通量高、结果精准、试剂节约等特点,这些优点十分符合目前对单分子、单细胞研究的要求。因此在近些年来,微流控芯片技术在单分子 ...
