标题:表面活性离子液体和表面活性季铵盐的合成,表征到抗菌特性
摘要:目前的工作为表面活性离子液体 (Sail) 和表面活性季铵盐 (表面活性 Qas) 的持续潜力提供了新的证据.为了实现这一目标,合成了一系列产率为 >=85% 的化合物,并研究了它们的热分析.此外,还研究了对人类病原微生物和土壤微生物的抗菌活性.随后,探索了它们的表面特性,目的是利用 Sail 和表面活性 Qas 作为商业两亲性化合物的替代品.最后,我们分析了不同温度 (5 至 25 OC) 农田中植物叶片表面的润湿性和叶片模型植物膜的润湿性.我们的结果表明,合成的化合物表现出比其商业类似物更高的活性,例如二癸基二甲基氯化铵 (Ddac) 和十二烷基三甲基溴化铵 (C12Tab),它们的 Cmc 值为 2 Mm 和 15 Mm.合成化合物的抗菌性能的有效性取决于其疏水性和截止效应.此外,在 25 °c 时观察到叶片表面的最佳润湿性. 我们的研究对 Sail 和表面活性 Qas 作为多功能化合

摘要:The present invention relates to cationic and polycationic compositions and methods for enhancing synthesis of nucleic acid molecules. In a preferred aspect, the invention relates to inhibition or control of nucleic acid synthesis, sequencing or amplification. Specifically, the present invention discloses cationic and polycationic molecules, compounds, and compositions having affinity for double-stranded and/or single-stranded nucleic acid molecules and/or single-stranded/double-stranded nucleic acid complexes (e.g., primer/template complexes, double-stranded templates, single-stranded templates or single-stranded primers) for use in such enhanced synthesis. The cationic and polycationic molecules, compounds, and compositions of the invention are capable of inhibiting nonspecific nucleic acid synthesis at ambient temperature. Thus, in a preferred aspect, the invention relates to “hot startâ€? synthesis of nucleic acid molecules. Accordingly, the invention prevents non-specific nucleic acid synthesis at low temperatures, for example during reaction set up. The invention also relates to kits for synthesizing, amplifying, reverse transcribing or sequencing nucleic acid molecules comprising one or more of the cationic and polycationic molecules, compounds, and compositions of the invention. The invention also relates to compositions prepared for carrying out the methods of the invention and to compositions made after or during such methods. The invention also generally relates to compositions useful for inhibiting or preventing degradation of various nucleic acid molcules.

标题 :Materials and methods for modulation of tendon healing
发明人：GILCHRIST DEREK STEWART; MILLAR NEAL LINDSAY
权利人:UNIV GLASGOW COURT
摘要:The invention relates to the use of microRNA 29 and precursors and mimics thereof for the modulation of tendon injury and the biomechanical properties of tendon. In particular, the invention derives from the finding that synthesis of type 1 collagen in tenocytes is less sensitive to miR-29 than is synthesis of type 3 collagen, thus enabling the balance between the collagen subtypes to be modulated in favor of type 1 collagen, mitigating reduction in biomechanical properties during healing.
