With the self-emulsifying aqueous polyurethane containing polymeric double bond in the lateral chain acted as macromolecular emulsor and reactant for acrylate monomer polymerization, controlling the reaction amount of polymeric double bond so that adjusting the chemical bond linkage degree between polyurethane and acrylate, core-shell type interpenetrating polymer network structural aqueous acrylate polyurethane hybrid dispersion was synthesized, which is now a new type molecular composite technology for aqueous polyurethane.

利用侧链含可聚双键的自乳化聚氨酯水分散体作为丙烯酸酯单体聚合反应的高分子乳化剂和反应物，通过控制聚氨酯水分散体侧链上参与共聚的双键数目，调节聚氨酯和丙烯酸酯的化学键合程度，制备得到核壳型互穿网络结构丙烯酸聚氨酯杂合水分散体是一种新颖的复合改性技术。

In this paper, PCR primers were designed based on the sequence of a single copy in atp6 gene. A 500bp fragment was amplified, and then the PCR products were digested with restriction enzym BglII.

根据atp6的基因序列设计特异扩增引物，以瓣化型胡萝卜核质互作雄性不育系H05A及其保持系H05B为试材，扩增获得了1条约500bp的特异扩增片段。

High-level nuclear β-catenin staining serves as a useful diagnostic tool for desmoid-type fibromatosis. The high expression of ER-β in desmoid-type fibromatosis provides a biological mechanism for the antiestrogenic compounds to treat fibromatosis.

高水平β-catenin核阳性表达可用于辅助韧带样型纤维瘤病诊断以及与其它梭形细胞肿瘤的鉴别诊断。

The strongest evidence for linkage in 147 families with late-onset PD was on chromosome 17 near the tau gene -- previously shown to be involved in other neurodegenerative diseases including frontotemporal dementia with parkinsonism and progressive supranuclear palsy.

147个患有迟发型帕金森氏症的家庭在遗传研究中被发现，该病与17号染色体上的tau基因有关联。以前tau基因被认为与其它的神经变性疾病有关，如伴有震颤麻痹的额颞型痴呆以及进行性核上性麻痹有关。

During conjugation, the complementary mating type cells unite pairwise undergo meiosis, exchange gametic nuclei and separate again.

在接合生殖期间，交配型互补的细胞相互识别配对，进行减数分裂、交换配子核，然后分开。

Results: More digestion of nucleus collagens, especially type I 、 II collagens, were observed through low speed guttatim epidural injection of collagenase.

In this study, Mono-nuclear cells containing hematopoietic stem/progenitor cells were isolated from umbilical cord blood of normal full-term deliveries, healthy adult and heterocellular HPFH patient bone marrow by density gradient centrifugation. After simple purification and expansion in vitro, MNCs were induced to erythroid cell differentiation using different culture systems and cytokines including Epo, IL-3 and GM-CSF.

本研究首先利用密度梯度离心方法，从正常成人和异细胞型遗传性胎儿血红蛋白持续存在综合症家系患者的骨髓组织、健康足月正常分娩胎儿脐带血中分离得到了含有造血干／祖细胞的单个核细胞(Mono-Nuclear Cell，MNC)，进行初步纯化及体外扩增后，组合使用Epo、IL-3、GM-CSF等细胞因子，将造血干／祖细胞向红系方向进行诱导培养。

Results indicated that suppression of malignancy was observed in the hybrid cells, they became differentiated morphologically and functionally by:(1) changes in histochemical staining, nucleus-cytoplasm in ratio, and increase in cell size and nucleal heterochromation, but decrese in cell surface microvilli and number of nucleoli;(2) decrease of growth rate, mitotic index and DNA synthesis rate;(3) loss of the ability to growth in soft agar medium, and non-tumorigenic under heterotransplantation to nude mice;(4) reduction of chromosome number mainly of rat derivative and decrease in chromosomal aberration rate.

实验结果表明：（1）杂交细胞出现瘤细胞与网织红细胞杂交同样的表型逆转及去恶性化特征，主要表现在细胞体积增大、核质比例减小；DNA合同速率降低、分裂指数下降，细胞生长显著减慢；在软琼脂中不形成集落，在裸鼠体内失去了长瘤能力。
