New Phytologist, Volume 247, Issue 5, Page 2086-2097, September 2025.Summary The importance of marine angiosperms, or seagrasses, as foundation species for marine coastal ecosystems is in marked contrast to their low species number of only 70 described taxa. Seagrass species tend to have very similar overall morphologies dictated by hydrodynamic forces of the ocean environment.

Veterinary Dermatology, Volume 36, Issue 3, Page 302-313, June 2025.Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several

Gelatin-siloxane nanoparticles decorated with functional biomolecules as non-viral vectors for in vitro trial on gene expression level [PDF]
, 2010 明胶-硅氧烷纳米粒子（GSNPs）是本课题组之前开发的一种有机-无机杂化纳米粒子。它具有很好的生物相容性以及DNA的包裹和释放能力。先前的研究表明穿膜多肽Tat修饰GSNPs可以提高其进入细胞的效率，因此本文旨在通过其它功能性的生物分子修饰GSNPs从而赋予其在基因及其它治疗性小分子递送方面的多功能作用。具体研究内容包括： （1）将膜融合肽八聚精氨酸（R8）和流感病毒血凝素蛋白亚基HA2修饰到GSNPs表面以提高纳米粒子逃逸溶酶体的效率，从而最终提高其基因转染的效率。通过流式细胞仪比较了R8-GS ...

Cellular traffic and in vitro transfection of functional peptides decorated gelatin–siloxane nanoparticles as non-viral vectors [PDF]
, 2009 基因治疗能够从基因组水平治愈人类疾病。非病毒载体相对病毒载体具有较好的生物相容性，但其基因递送和转染效率都较低。本课题组合成的明胶-硅氧烷纳米粒子是一种新颖的有机-无机纳米杂化材料，具有较好的DNA包封和释放性能。但是有关基于明胶-硅氧烷的纳米粒子作为非病毒基因载体的潜能还缺乏深入系统的研究。本文针对基因治疗中的主要屏障，就基于明胶-硅氧烷的纳米粒子作为理想非病毒载体的可行性，开展了一系列的研究，主要包括： （1）通过MTT实验对明胶-硅氧烷纳米粒子（GSNPs）和Tat修饰的明胶-硅氧烷纳米粒子 ...
