  自内标荧光超灵敏检测 mtDNA 评估母系遗传缺陷水平

  摘要：

  线粒体DNA（mtDNA）是一种以母系遗传为特征的独特遗传物质。它具有缺乏组蛋白保护的圆形结构，并且细胞丰度较低，这对其在活细胞水平上的灵敏和选择性检测提出了巨大的挑战。在这里，我们设计了三种具有不同接头长度的双萘酰亚胺探针（NANn-OH，n = 0,2,6），促进在自由状态下形成不同的扭曲或折叠分子构象。这些探针发射约 627 nm 的红色荧光，具有不同的荧光量子产率（Φ NAN0-OH = 0.0016、Φ NAN2-OH = 0.0136 和 Φ NAN6-OH = 0.0125）。当遇到 mtDNA (0.4–3.4 μg/mL) 时，这些探针会根据所附着的 C 链长度发生构象变化，并在 453 nm 附近表现出逐渐增强的荧光信号。荧光强度分别增加至13.5倍、1.9倍和8.2倍。值得注意的是，627 nm 附近的红色荧光强度在整个过程中保持恒定，从而作为比例荧光信号增强的固有校正机制，以提高选择性和灵敏度。

  outstanding guest responsive morphology transition properties. The morphology tuning studies was efficiently achieved with the addition of competitive guest molecules G1 and G2 by various self-assembly mechanisms. C3-PLT itself displays nanofiber morphology through H-type π-π stacking, and this nanofiber morphology can be completely transformed into spherical vesicles by host-guest interaction G1,

  摘要成功合成了基于苯-1,3,5-三甲苯酰胺（BTA）的星形桥接柱[5]芳烃三聚体（C3-PLT），其表现出优异的客体响应形态学转变特性。通过各种自组装机制，通过添加竞争性客体分子G1和G2，可以有效地完成形态调整研究。C3-PLT本身通过H型π-π堆叠显示出纳米纤维形态，并且这种纳米纤维形态可以通过宿主-客体相互作用G1完全转化为球形囊泡，而在通过“外壁”将G2添加到C3-PLT中时在电子转移相互作用中，可以观察到薄片的上层结构。SEM，1H NMR，DOSY，荧光光谱和粘度已验证了两个客体的超分子聚合物的形成和C3-PLT之间的形态学转变。

  A wholly aromatic polyester composition comprising (a) 100 parts by weight of a wholly aromatic polyester containing as a main component at least one compound selected from the group consisting of aromatic dicarboxylic acids, aromatic dihydroxy compounds and aromatic hydroxycarboxylic acids, and (b) from 5 to 300 parts by weight of a low-molecular-weight compound being substantially non-reactive with the wholly aromatic polyester and having a boiling point of at least about 200°C under atmospheric pressure and a molecular weight of not more than 1.000. The wholly aromatic polyester composition is produced advantageously by polycondensing in the molten state the polyester-forming starting mixture in the presence of the low-molecular-weight compound. A film-like or fibrous article of a wholly aromatic polyester may be produced by extracting the low-molecular-weight compound from a film-like or fibrous article of the wholly aromatic polyester composition.

  A process for producing a film-like or fibrous structure of an aromatic polyester, which comprises (1) forming an unstretched film-like or fibrous structure by melt-shaping a blend comprising 100 parts by weight of (A) an aromatic polyester having a high degree of polymerization derived from an aromatic dicarboxylic acid as a main acid component and an aliphatic diol and/or an alicyclic diol as a main glycol component and (B) 3 to 300 parts by weight of a low-molecular-weight compound being substantially non-reactive with the aromatic polyester (A) and having a boiling point of at least about 200°C under atmospheric pressure and a molecular weight of not more than 1,000, (2) stretching the resulting film-like or fibrous structure, (3) extracting at least a major portion of the low-molecular-weight compound from the stretched film-like or fibrous structure by using an organic solvent which does not substantially dissolve the aromatic polyester under the extracting conditions, and (4) if desired, heat-setting the film-like or fibrous structure after the stretching step (2) and/or the extracting step (3). The film-like or fibrous structure of an aromatic polyester prepared by the process substantially contains no low-molecular-weight compound or contains the low-molecular-weight compound in an amount of up to about 1 part by weight at most per 100 parts by weight of the aromatic polyester.

  New low molecular weight organic materials with a strong tendency towards glass formation and glass temperatures above room temperature were synthesized. These materials consist of twin molecules where two bulky groups, i.e. carbazole (Ca), 3,6-dibromocarbazole (DBrCa), 2,3-benzocarbazole (BC), 1,2-benzo-3,4-dihydrocarbazole (BCDH), phenothiazine (Ph), 1,8-naphthalic acid anhydride (NI), and pyrene-l-aldehyde (PY) have been linked by flexible or semiflexible aliphatic or aromatic central units. Their structure-glass temperature relationship and some relations between thermodynamic parameters and amorphous properties are discussed.
